You can also find out information how to buy cheap viagra online about Extra Help in many different languages. See Medicare Rights Center chart on Extra Help Income and Asset Limits - updated annually You can apply for Extra Help and MSP at the same time through SSA. SSA will forward your Extra Help application data to the New York State Department of Health, who will use that data to assess your eligibility for MSP.

Individuals who apply for LIS through SSA and those who are deemed into how to buy cheap viagra online LIS should receive written confirmation of their Extra Help status through SSA. Of course, individuals who apply for LIS through SSA and are found ineligible are also entitled to a written notice and have appeal rights. Benefits of Extra Help 1) Assistance with Part D cost-sharing The Extra Help program provides a subsidy which covers most (but not all) of beneficiary’s cost sharing obligations.

Extra Help beneficiaries do not have to worry about hitting the “donut hole” – the LIS subsidy continues to how to buy cheap viagra online cover them through the donut hole and into catastrophic coverage. Full Extra Help. LIS beneficiaries with incomes up to 135% FPL are generally eligible for "full" Extra Help -- meaning they pay no Part D deductible, no charge for monthly premiums up to the benchmark amount, and fixed, relatively low co-pays (between $1.30 and $8.95 for 2020 depending on the person's income level and the tier category of the drug.

Medicaid beneficiaries how to buy cheap viagra online in nursing homes, waiver programs, or managed long term care have $0 co-pays). Full Extra Help beneficiaries who hit the catastrophic coverage limit have $0 co-pays. See current co-pay levels here.

Partial Extra how to buy cheap viagra online Help. Beneficiaries between 135%-150% FPL receive "partial" Extra Help, which limits the Part D deductible to $89 (2020 figure - click here for updated chart). Sets sliding scale fees for monthly premiums.

And limits co-pays to 15%, until the beneficiary reaches the catastrophic coverage limit, at which point co-pays are limited to a $8.95 maximum (2020 or see current amount here) or 5% of the drug cost, how to buy cheap viagra online whichever is greater. 2) Facilitated enrollment into a Part D plan Extra Help recipients who aren’t already enrolled in a Part D plan and don’t want to choose one on their own will be automatically enrolled into a benchmark plan by CMS. This facilitated enrollment ensures that Extra Help recipients have Part D coverage.

However, the downside to facilitated enrollment is that the plan may not be the best “fit” for the beneficiary, if it doesn’t cover all his/her drugs, assesses a higher tier level for covered drugs than other comparable how to buy cheap viagra online plans, and/or requires the beneficiary to go through administrative hoops like prior authorization, quantity limits and/or step therapy. Fortunately, Extra Help recipients can always enroll in a new plan … see #3 below. 3) Continuous special enrollment period Extra Help recipients have a continuous special enrollment period, meaning that they can switch plans at any time.

They are not “locked into” the annual open enrollment period (October how to buy cheap viagra online 15-December 7). NOTE. This changed in 2019.

Starting in 2019, those with Extra Help how to buy cheap viagra online will no longer have a continuous enrollment period. Instead, Extra Help recipients will be eligible to enroll no more than once per quarter for each of the first three quarters of the year. 4) No late enrollment penalty Non LIS beneficiaries generally face a premium penalty (higher monthly premium) if they delayed their enrollment into Part D, meaning that they didn’t enroll when they were initially eligible and didn’t have “creditable coverage.” Extra Help recipients do not have to worry about this problem – the late enrollment penalty provision does not apply to LIS beneficiaries.

1) For “deemed” beneficiaries (Medicaid/Medicare Savings Program recipients) how to buy cheap viagra online. Extra Help status lasts at least until the end of the current calendar year, even if the individual loses their Medicaid or Medicare Savings Program coverage during that year. Individuals who receive Medicaid or a Medicare Savings Program any month between July and December keep their LIS status for the remainder of that calendar year and the following year.

Getting Medicaid coverage for how to buy cheap viagra online even just a short period of time (ie, meeting a spenddown for just one month) can help ensure that the individual obtains Extra Help coverage for at least 6 months, and possibly as long as 18 months. TIP. People with a high spend-down who want to receive Medicaid for just one month in order to get Extra Help for 6-18 months can use past medical bills to meet their spend-down for that one month.

There are different rules for using past paid medical bills verses past how to buy cheap viagra online unpaid medical bills. For information see Spend down training materials. Individuals who are losing their deemed status at the end of a calendar year because they are no longer receiving Medicaid or the Medicare Savings Program should be notified in advance by SSA, and given an opportunity to file an Extra Help application through SSA.

2) For “non-deemed” beneficiaries (those how to buy cheap viagra online who filed their LIS applications through SSA) Non-deemed beneficiaries retain their LIS status until/unless SSA does a redetermination and finds the individual ineligible for Extra Help. There are no reporting requirements per se in the Extra Help program, but beneficiaries must respond to SSA’s redetermination request. What to do if the Part D plan doesn't know that someone has Extra Help Sometimes there are lengthy delays between the date that someone is approved for Medicaid or a Medicare Savings Program and when that information is formally conveyed to the Part D plan by CMS.

As a practical matter, this often results in beneficiaries being charged co-pays, premiums and/or deductibles that they can't afford how to buy cheap viagra online and shouldn't have to pay. To protect LIS beneficiaries, CMS has a "Best Available Evidence" policy which requires plans to accept alternative forms of proof of someone's LIS status and adjust the person's cost-sharing obligation accordingly. LIS beneficiaries who are being charged improperly should be sure to contact their plan and provide proof of their LIS status.

If the plan still won't recognize their LIS status, the person or their advocate should file a complaint with the CMS how to buy cheap viagra online regional office. The federal regulations governing the Low Income Subsidy program can be found at 42 CFR Subpart P (sections 423.771 through 423.800). Also, CMS provides detailed guidance on the LIS provisions in chapter 13 of its Medicare Prescription Drug Benefit Manual.

This article was how to buy cheap viagra online authored by the Empire Justice Center.Medicare Savings Programs (MSPs) pay for the monthly Medicare Part B premium for low-income Medicare beneficiaries and qualify enrollees for the "Extra Help" subsidy for Part D prescription drugs. There are three separate MSP programs, the Qualified Medicare Beneficiary (QMB) Program, the Specified Low Income Medicare Beneficiary (SLMB) Program and the Qualified Individual (QI) Program, each of which is discussed below. Those in QMB receive additional subsidies for Medicare costs.

Since April 1, 2008, none of the three MSP programs have resource limits in New York -- which means many Medicare beneficiaries who might not qualify for Medicaid because of excess resources can qualify for an MSP. 1.A.

(No retro for January application). See GIS 07 MA 027. Can Enroll in MSP and Medicaid at Same Time?.

YES YES NO!. Must choose between QI-1 and Medicaid. Cannot have both, not even Medicaid with a spend-down.

2. INCOME LIMITS and RULES Each of the three MSP programs has different income eligibility requirements and provides different benefits. The income limits are tied to the Federal Poverty Level (FPL).

2019 FPL levels were released by NYS DOH in GIS 20 MA/02 - 2020 Federal Poverty Levels -- Attachment II and have been posted by Medicaid.gov and the National Council on Aging and are in the chart below. NOTE. There is usually a lag in time of several weeks, or even months, from January 1st of each year until the new FPLs are release, and then before the new MSP income limits are officially implemented.

During this lag period, local Medicaid offices should continue to use the previous year's FPLs AND count the person's Social Security benefit amount from the previous year - do NOT factor in the Social Security COLA (cost of living adjustment). Once the updated guidelines are released, districts will use the new FPLs and go ahead and factor in any COLA. See 2019 Fact Sheet on MSP in NYS by Medicare Rights Center ENGLISH SPANISH Income is determined by the same methodology as is used for determining in eligibility for SSI The rules for counting income for SSI-related (Aged 65+, Blind, or Disabled) Medicaid recipients, borrowed from the SSI program, apply to the MSP program, except for the new rules about counting household size for married couples.

L. 367-a(3)(c)(2), NYS DOH 2000-ADM-7, 89-ADM-7 p.7. Gross income is counted, although there are certain types of income that are disregarded.

The most common income disregards, also known as deductions, include. (a) The first $20 of your &. Your spouse's monthly income, earned or unearned ($20 per couple max).

(b) SSI EARNED INCOME DISREGARDS. * The first $65 of monthly wages of you and your spouse, * One-half of the remaining monthly wages (after the $65 is deducted). * Other work incentives including PASS plans, impairment related work expenses (IRWEs), blind work expenses, etc.

For information on these deductions, see The Medicaid Buy-In for Working People with Disabilities (MBI-WPD) and other guides in this article -- though written for the MBI-WPD, the work incentives apply to all Medicaid programs, including MSP, for people age 65+, disabled or blind. (c) monthly cost of any health insurance premiums but NOT the Part B premium, since Medicaid will now pay this premium (may deduct Medigap supplemental policies, vision, dental, or long term care insurance premiums, and the Part D premium but only to the extent the premium exceeds the Extra Help benchmark amount) (d) Food stamps not counted. You can get a more comprehensive listing of the SSI-related income disregards on the Medicaid income disregards chart.

As for all benefit programs based on financial need, it is usually advantageous to be considered a larger household, because the income limit is higher. The above chart shows that Households of TWO have a higher income limit than households of ONE. The MSP programs use the same rules as Medicaid does for the Disabled, Aged and Blind (DAB) which are borrowed from the SSI program for Medicaid recipients in the “SSI-related category.” Under these rules, a household can be only ONE or TWO.

18 NYCRR 360-4.2. See DAB Household Size Chart. Married persons can sometimes be ONE or TWO depending on arcane rules, which can force a Medicare beneficiary to be limited to the income limit for ONE person even though his spouse who is under 65 and not disabled has no income, and is supported by the client applying for an MSP.

EXAMPLE. Bob's Social Security is $1300/month. He is age 67 and has Medicare.

His wife, Nancy, is age 62 and is not disabled and does not work. Under the old rule, Bob was not eligible for an MSP because his income was above the Income limit for One, even though it was well under the Couple limit. In 2010, NYS DOH modified its rules so that all married individuals will be considered a household size of TWO.

DOH GIS 10 MA 10 Medicare Savings Program Household Size, June 4, 2010. This rule for household size is an exception to the rule applying SSI budgeting rules to the MSP program. Under these rules, Bob is now eligible for an MSP.

When is One Better than Two?. Of course, there may be couples where the non-applying spouse's income is too high, and disqualifies the applying spouse from an MSP. In such cases, "spousal refusal" may be used SSL 366.3(a).

(Link is to NYC HRA form, can be adapted for other counties). 3. The Three Medicare Savings Programs - what are they and how are they different?.

1. Qualified Medicare Beneficiary (QMB). The QMB program provides the most comprehensive benefits.

Available to those with incomes at or below 100% of the Federal Poverty Level (FPL), the QMB program covers virtually all Medicare cost-sharing obligations. Part B premiums, Part A premiums, if there are any, and any and all deductibles and co-insurance. QMB coverage is not retroactive.

The program’s benefits will begin the month after the month in which your client is found eligible. ** See special rules about cost-sharing for QMBs below - updated with new CMS directive issued January 2012 ** See NYC HRA QMB Recertification form ** Even if you do not have Part A automatically, because you did not have enough wages, you may be able to enroll in the Part A Buy-In Program, in which people eligible for QMB who do not otherwise have Medicare Part A may enroll, with Medicaid paying the Part A premium (Materials by the Medicare Rights Center). 2.

Specifiedl Low-Income Medicare Beneficiary (SLMB). For those with incomes between 100% and 120% FPL, the SLMB program will cover Part B premiums only. SLMB is retroactive, however, providing coverage for three months prior to the month of application, as long as your client was eligible during those months.

3. Qualified Individual (QI-1). For those with incomes between 120% and 135% FPL, and not receiving Medicaid, the QI-1 program will cover Medicare Part B premiums only.

QI-1 is also retroactive, providing coverage for three months prior to the month of application, as long as your client was eligible during those months. However, QI-1 retroactive coverage can only be provided within the current calendar year. (GIS 07 MA 027) So if you apply in January, you get no retroactive coverage.

Q-I-1 recipients would be eligible for Medicaid with a spend-down, but if they want the Part B premium paid, they must choose between enrolling in QI-1 or Medicaid. They cannot be in both. It is their choice.

DOH MRG p. 19. In contrast, one may receive Medicaid and either QMB or SLIMB.

4. Four Special Benefits of MSPs (in addition to NO ASSET TEST). Benefit 1.

Back Door to Medicare Part D "Extra Help" or Low Income Subsidy -- All MSP recipients are automatically enrolled in Extra Help, the subsidy that makes Part D affordable. They have no Part D deductible or doughnut hole, the premium is subsidized, and they pay very low copayments. Once they are enrolled in Extra Help by virtue of enrollment in an MSP, they retain Extra Help for the entire calendar year, even if they lose MSP eligibility during that year.

The "Full" Extra Help subsidy has the same income limit as QI-1 - 135% FPL. However, many people may be eligible for QI-1 but not Extra Help because QI-1 and the other MSPs have no asset limit. People applying to the Social Security Administration for Extra Help might be rejected for this reason.

Recent (2009-10) changes to federal law called "MIPPA" requires the Social Security Administration (SSA) to share eligibility data with NYSDOH on all persons who apply for Extra Help/ the Low Income Subsidy. Data sent to NYSDOH from SSA will enable NYSDOH to open MSP cases on many clients. The effective date of the MSP application must be the same date as the Extra Help application.

Signatures will not be required from clients. In cases where the SSA data is incomplete, NYSDOH will forward what is collected to the local district for completion of an MSP application. The State implementing procedures are in DOH 2010 ADM-03.

Also see CMS "Dear State Medicaid Director" letter dated Feb. 18, 2010 Benefit 2. MSPs Automatically Waive Late Enrollment Penalties for Part B Generally one must enroll in Part B within the strict enrollment periods after turning age 65 or after 24 months of Social Security Disability.

An exception is if you or your spouse are still working and insured under an employer sponsored group health plan, or if you have End Stage Renal Disease, and other factors, see this from Medicare Rights Center. If you fail to enroll within those short periods, you might have to pay higher Part B premiums for life as a Late Enrollment Penalty (LEP). Also, you may only enroll in Part B during the Annual Enrollment Period from January 1 - March 31st each year, with Part B not effective until the following July.

Enrollment in an MSP automatically eliminates such penalties... For life.. Even if one later ceases to be eligible for the MSP.

AND enrolling in an MSP will automatically result in becoming enrolled in Part B if you didn't already have it and only had Part A. See Medicare Rights Center flyer. Benefit 3.

No Medicaid Lien on Estate to Recover MSP Benefits Paid Generally speaking, states may place liens on the Estates of deceased Medicaid recipients to recover the cost of Medicaid services that were provided after the recipient reached the age of 55. Since 2002, states have not been allowed to recover the cost of Medicare premiums paid under MSPs. In 2010, Congress expanded protection for MSP benefits.

Beginning on January 1, 2010, states may not place liens on the Estates of Medicaid recipients who died after January 1, 2010 to recover costs for co-insurance paid under the QMB MSP program for services rendered after January 1, 2010. The federal government made this change in order to eliminate barriers to enrollment in MSPs. See NYS DOH GIS 10-MA-008 - Medicare Savings Program Changes in Estate Recovery The GIS clarifies that a client who receives both QMB and full Medicaid is exempt from estate recovery for these Medicare cost-sharing expenses.

Benefit 4. SNAP (Food Stamp) benefits not reduced despite increased income from MSP - at least temporarily Many people receive both SNAP (Food Stamp) benefits and MSP. Income for purposes of SNAP/Food Stamps is reduced by a deduction for medical expenses, which includes payment of the Part B premium.

Since approval for an MSP means that the client no longer pays for the Part B premium, his/her SNAP/Food Stamps income goes up, so their SNAP/Food Stamps go down. Here are some protections. Do these individuals have to report to their SNAP worker that their out of pocket medical costs have decreased?.

And will the household see a reduction in their SNAP benefits, since the decrease in medical expenses will increase their countable income?. The good news is that MSP households do NOT have to report the decrease in their medical expenses to the SNAP/Food Stamp office until their next SNAP/Food Stamp recertification. Even if they do report the change, or the local district finds out because the same worker is handling both the MSP and SNAP case, there should be no reduction in the household’s benefit until the next recertification.

New York’s SNAP policy per administrative directive 02 ADM-07 is to “freeze” the deduction for medical expenses between certification periods. Increases in medical expenses can be budgeted at the household’s request, but NYS never decreases a household’s medical expense deduction until the next recertification. Most elderly and disabled households have 24-month SNAP certification periods.

Eventually, though, the decrease in medical expenses will need to be reported when the household recertifies for SNAP, and the household should expect to see a decrease in their monthly SNAP benefit. It is really important to stress that the loss in SNAP benefits is NOT dollar for dollar. A $100 decrease in out of pocket medical expenses would translate roughly into a $30 drop in SNAP benefits.

See more info on SNAP/Food Stamp benefits by the Empire Justice Center, and on the State OTDA website. Some clients will be automatically enrolled in an MSP by the New York State Department of Health (NYSDOH) shortly after attaining eligibility for Medicare. Others need to apply.

The 2010 "MIPPA" law introduced some improvements to increase MSP enrollment. See 3rd bullet below. Also, some people who had Medicaid through the Affordable Care Act before they became eligible for Medicare have special procedures to have their Part B premium paid before they enroll in an MSP.

See below. WHO IS AUTOMATICALLY ENROLLED IN AN MSP. Clients receiving even $1.00 of Supplemental Security Income should be automatically enrolled into a Medicare Savings Program (most often QMB) under New York State’s Medicare Savings Program Buy-in Agreement with the federal government once they become eligible for Medicare.

They should receive Medicare Parts A and B. Clients who are already eligible for Medicare when they apply for Medicaid should be automatically assessed for MSP eligibility when they apply for Medicaid. (NYS DOH 2000-ADM-7 and GIS 05 MA 033).

Clients who apply to the Social Security Administration for Extra Help, but are rejected, should be contacted &. Enrolled into an MSP by the Medicaid program directly under new MIPPA procedures that require data sharing. Strategy TIP.

Since the Extra Help filing date will be assigned to the MSP application, it may help the client to apply online for Extra Help with the SSA, even knowing that this application will be rejected because of excess assets or other reason. SSA processes these requests quickly, and it will be routed to the State for MSP processing. Since MSP applications take a while, at least the filing date will be retroactive.

Note. The above strategy does not work as well for QMB, because the effective date of QMB is the month after the month of application. As a result, the retroactive effective date of Extra Help will be the month after the failed Extra Help application for those with QMB rather than SLMB/QI-1.

Applying for MSP Directly with Local Medicaid Program. Those who do not have Medicaid already must apply for an MSP through their local social services district. (See more in Section D.

Below re those who already have Medicaid through the Affordable Care Act before they became eligible for Medicare. If you are applying for MSP only (not also Medicaid), you can use the simplified MSP application form (theDOH-4328(Rev. 8/2017-- English) (2017 Spanish version not yet available).

Either application form can be mailed in -- there is no interview requirement anymore for MSP or Medicaid. See 10 ADM-04. Applicants will need to submit proof of income, a copy of their Medicare card (front &.

Back), and proof of residency/address. See the application form for other instructions. One who is only eligible for QI-1 because of higher income may ONLY apply for an MSP, not for Medicaid too.

One may not receive Medicaid and QI-1 at the same time. If someone only eligible for QI-1 wants Medicaid, s/he may enroll in and deposit excess income into a pooled Supplemental Needs Trust, to bring her countable income down to the Medicaid level, which also qualifies him or her for SLIMB or QMB instead of QI-1. Advocates in NYC can sign up for a half-day "Deputization Training" conducted by the Medicare Rights Center, at which you'll be trained and authorized to complete an MSP application and to submit it via the Medicare Rights Center, which submits it to HRA without the client having to apply in person.

Enrolling in an MSP if you already have Medicaid, but just become eligible for Medicare Those who, prior to becoming enrolled in Medicare, had Medicaid through Affordable Care Act are eligible to have their Part B premiums paid by Medicaid (or the cost reimbursed) during the time it takes for them to transition to a Medicare Savings Program. In 2018, DOH clarified that reimbursement of the Part B premium will be made regardless of whether the individual is still in a Medicaid managed care (MMC) plan. GIS 18 MA/001 Medicaid Managed Care Transition for Enrollees Gaining Medicare ( PDF) provides, "Due to efforts to transition individuals who gain Medicare eligibility and who require LTSS, individuals may not be disenrolled from MMC upon receipt of Medicare.

To facilitate the transition and not disadvantage the recipient, the Medicaid program is approving reimbursement of Part B premiums for enrollees in MMC." The procedure for getting the Part B premium paid is different for those whose Medicaid was administered by the NYS of Health Exchange (Marketplace), as opposed to their local social services district. The procedure is also different for those who obtain Medicare because they turn 65, as opposed to obtaining Medicare based on disability. Either way, Medicaid recipients who transition onto Medicare should be automatically evaluated for MSP eligibility at their next Medicaid recertification.

NYS DOH 2000-ADM-7 Individuals can also affirmatively ask to be enrolled in MSP in between recertification periods. IF CLIENT HAD MEDICAID ON THE MARKETPLACE (NYS of Health Exchange) before obtaining Medicare. IF they obtain Medicare because they turn age 65, they will receive a letter from their local district asking them to "renew" Medicaid through their local district.

See 2014 LCM-02. Now, their Medicaid income limit will be lower than the MAGI limits ($842/ mo reduced from $1387/month) and they now will have an asset test. For this reason, some individuals may lose full Medicaid eligibility when they begin receiving Medicare.

People over age 65 who obtain Medicare do NOT keep "Marketplace Medicaid" for 12 months (continuous eligibility) See GIS 15 MA/022 - Continuous Coverage for MAGI Individuals. Since MSP has NO ASSET limit. Some individuals may be enrolled in the MSP even if they lose Medicaid, or if they now have a Medicaid spend-down.

If a Medicare/Medicaid recipient reports income that exceeds the Medicaid level, districts must evaluate the person’s eligibility for MSP. 08 OHIP/ADM-4 ​If you became eligible for Medicare based on disability and you are UNDER AGE 65, you are entitled to keep MAGI Medicaid for 12 months from the month it was last authorized, even if you now have income normally above the MAGI limit, and even though you now have Medicare. This is called Continuous Eligibility.

EXAMPLE. Sam, age 60, was last authorized for Medicaid on the Marketplace in June 2016. He became enrolled in Medicare based on disability in August 2016, and started receiving Social Security in the same month (he won a hearing approving Social Security disability benefits retroactively, after first being denied disability).

Even though his Social Security is too high, he can keep Medicaid for 12 months beginning June 2016. Sam has to pay for his Part B premium - it is deducted from his Social Security check. He may call the Marketplace and request a refund.

This will continue until the end of his 12 months of continues MAGI Medicaid eligibility. He will be reimbursed regardless of whether he is in a Medicaid managed care plan. See GIS 18 MA/001 Medicaid Managed Care Transition for Enrollees Gaining Medicare (PDF) When that ends, he will renew Medicaid and apply for MSP with his local district.

Individuals who are eligible for Medicaid with a spenddown can opt whether or not to receive MSP. (Medicaid Reference Guide (MRG) p. 19).

Obtaining MSP may increase their spenddown. MIPPA - Outreach by Social Security Administration -- Under MIPPA, the SSA sends a form letter to people who may be eligible for a Medicare Savings Program or Extra Help (Low Income Subsidy - LIS) that they may apply. The letters are.

· Beneficiary has Extra Help (LIS), but not MSP · Beneficiary has no Extra Help (LIS) or MSP 6. Enrolling in MSP for People Age 65+ who do Not have Free Medicare Part A - the "Part A Buy-In Program" Seniors WITHOUT MEDICARE PART A or B -- They may be able to enroll in the Part A Buy-In program, in which people eligible for QMB who are age 65+ who do not otherwise have Medicare Part A may enroll in Part A, with Medicaid paying the Part A premium. See Step-by-Step Guide by the Medicare Rights Center).

This guide explains the various steps in "conditionally enrolling" in Part A at the SSA office, which must be done before applying for QMB at the Medicaid office, which will then pay the Part A premium. See also GIS 04 MA/013. In June, 2018, the SSA revised the POMS manual procedures for the Part A Buy-In to to address inconsistencies and confusion in SSA field offices and help smooth the path for QMB enrollment.

The procedures are in the POMS Section HI 00801.140 "Premium-Free Part A Enrollments for Qualified Medicare BenefiIaries." It includes important clarifications, such as. SSA Field Offices should explain the QMB program and conditional enrollment process if an individual lacks premium-free Part A and appears to meet QMB requirements. SSA field offices can add notes to the “Remarks” section of the application and provide a screen shot to the individual so the individual can provide proof of conditional Part A enrollment when applying for QMB through the state Medicaid program.

Beneficiaries are allowed to complete the conditional application even if they owe Medicare premiums. In Part A Buy-in states like NYS, SSA should process conditional applications on a rolling basis (without regard to enrollment periods), even if the application coincides with the General Enrollment Period. (The General Enrollment Period is from Jan 1 to March 31st every year, in which anyone eligible may enroll in Medicare Part A or Part B to be effective on July 1st).

7. What happens after the MSP approval - How is Part B premium paid For all three MSP programs, the Medicaid program is now responsible for paying the Part B premiums, even though the MSP enrollee is not necessarily a recipient of Medicaid. The local Medicaid office (DSS/HRA) transmits the MSP approval to the NYS Department of Health – that information gets shared w/ SSA and CMS SSA stops deducting the Part B premiums out of the beneficiary’s Social Security check.

SSA also refunds any amounts owed to the recipient. (Note. This process can take awhile!.

!. !. ) CMS “deems” the MSP recipient eligible for Part D Extra Help/ Low Income Subsidy (LIS).

​Can the MSP be retroactive like Medicaid, back to 3 months before the application?. ​The answer is different for the 3 MSP programs. QMB -No Retroactive Eligibility – Benefits begin the month after the month of the MSP application.

18 NYCRR § 360-7.8(b)(5) SLIMB - YES - Retroactive Eligibility up to 3 months before the application, if was eligible This means applicant may be reimbursed for the 3 months of Part B benefits prior to the month of application. QI-1 - YES up to 3 months but only in the same calendar year. No retroactive eligibility to the previous year.

Many athletes have had go to this site their viagra pills for men baseball season shortened or cancelled due to erectile dysfunction treatment. This extra rest can be helpful in decreasing stress on the shoulder and elbow joints, but it can also lead to decreased strength and ROM. Overhead athletes need to keep their bodies strong, and a great way to achieve that is by performing a regular strengthening program. With many gyms remaining closed or viagra pills for men limiting access during social distancing, that can be even more challenging. However, there are many exercises that can be done at home with minimal equipment needs.

A great program to focus on during the off season is the Thrower’s Ten program that was developed with the overhead athlete in mind. These exercises focus on the muscle viagra pills for men groups that matter most for the overhead athlete. We use our entire body to throw a ball and the stress on the shoulder to decelerate the arm is about twice our body weight. Most of this stress gets placed on the rotator cuff and scapular muscles that slow the arm down as we follow through with our throw. Weakness in these muscles can lead to problems with the shoulder viagra pills for men and elbow joints.

Common injuries can be Little League shoulder and elbow or strains to the ulnar collateral ligaments (Tommy John). If you have dealt with pain or injuries in the past, a comprehensive evaluation by a physical therapist (PT) who focuses on treating the overhead athlete can be extremely helpful in identifying areas of concern. Your PT will evaluate your strength with a dynamometer to look at any significant abnormalities viagra pills for men between shoulders. They can also perform a video throwing analysis to look at ways to potentially reduce injury risk and improve performance.

The odds are it’s not available to you, and there is a reason for that viagra pills for men. You may be hearing about how virtual care, often described as telehealth or telemedicine, is beneficial during erectile dysfunction treatment and how health systems are offering virtual access like never before. There’s a reason for that, too. For the past few weeks I’ve seen Facebook posts daily from former nursing colleagues in metro Detroit, one of the hardest hit areas in the country, as they viagra pills for men provide front-line care to patients with erectile dysfunction treatment.

It makes me very proud to call these nurses my friends. As a former emergency department nurse, I recall the feeling of satisfaction knowing that I’ve helped someone on the worst day of their life. One of the best parts of being a nurse is knowing you matter to the only person in health care that viagra pills for men truly matters. The patient. Several years ago I made the difficult decision to no longer perform bedside nursing and become a nurse administrator.

The biggest loss from my transition is the feeling that what I viagra pills for men do matters to the patient. erectile dysfunction treatment has forced a lot of us to rethink the role we play in health care and what the real priority should be. Things that were top priorities three months ago have been rightfully cast aside to either care for patients in a viagra or prepare for the unknown future of, “When is our turn?. € For me, erectile dysfunction treatment has reignited the feeling that what I do matters as virtual care has become a viagra pills for men powerful tool on the forefront of care during this crisis. It has also shown that many of the powerful rules and regulations that limit virtual care are not needed and should be discarded permanently.

When I became the director of virtual care at our organization in 2015 I knew nothing about telehealth. Sure, I had seen a stroke robot in some Emergency Departments, and I had some friends viagra pills for men that told me their insurance company lets them FaceTime a doctor for free (spoiler alert. It’s not FaceTime). I was tech-savvy from a consumer perspective and a tech novice from an IT perspective. Nevertheless, my team and I spent the next few years learning as viagra pills for men we built one of the higher volume virtual care networks in the state of Michigan.

We discovered a lot of barriers that keep virtual care from actually making the lives of patients and providers better and we also became experts in working around those barriers. But, there were two obstacles that we could not overcome. Government regulation viagra pills for men and insurance provider willingness to cover virtual visits. These two barriers effectively cripple most legitimate attempts to provide value-added direct-to-consumer virtual care, which I define as using virtual care technologies to provide care outside of our brick-and-mortar facilities, most commonly in the patient home. The need to social distance, cancel appointments, close provider offices, keep from overloading emergency departments and urgent cares and shelter in place created instant demand for direct-to-consumer virtual care.

In all honesty, I’ve always considered direct-to-consumer virtual care to be the flashy, must-have holiday gift of the year that organizations are viagra pills for men convinced will be the way of the future. If a health system wants to provide on-demand access to patients for low-complexity acute conditions, they will easily find plenty of vendors that will sell them their app and their doctors and put the health system’s logo on it. What a health system will struggle with is to find is enough patient demand to cover the high cost. Remember my friends from earlier that viagra pills for men told me about the app their insurance gave them?. Nearly all of them followed that up by telling me they’ve never actually used it.

I am fortunate that I work for an organization that understands this and instead focuses on how can we provide care that our patients actually want and need from the doctors they want to see. Ironically, this fiscal year viagra pills for men we had a corporate top priority around direct-to-consumer virtual care. We wanted to expand what we thought were some successful pilots and perform 500 direct-to-consumer visits. This year has been one of the hardest of my leadership career because, frankly, http://www.wordsandbones.uni-tuebingen.de/symposium2016/?p=1 up until a month ago I was about to fail on this top priority. With only four months left, we were only about halfway there.

The biggest problem we ran into was viagra pills for men that every great idea a physician brought to me was instantly dead in the water because practically no insurance company would pay for it. There are (prior to erectile dysfunction treatment) a plethora of rules around virtual care billing but the simplest way to summarize it is that most virtual care will only be paid if it happens in a rural location and inside of a health care facility. It is extremely limited what will be paid for in the patient home and most of it is so specific that the average patient isn’t eligible to get any in-home virtual care. Therefore, most good medical uses for direct-to-consumer care would be asking the patient to pay cash or the physician to forgo reimbursement for a visit that viagra pills for men would be covered if it happened in office. Add to that the massive capital and operating expenses it takes to build a virtual care network and you can see why these programs don’t exist.

A month ago I was skeptical we’d have a robust direct-to-consumer program any time soon and then erectile dysfunction treatment hit. When erectile dysfunction treatment started to spread rapidly viagra pills for men in the United States, regulations and reimbursement rules were being stripped daily. The first change that had major impact is when the Centers for Medicare and Medicaid Services (CMS) announced that they would temporarily begin reimbursing for virtual visits conducted in the patient’s home for erectile dysfunction treatment and non-erectile dysfunction treatment related visits. We were already frantically designing a virtual program to handle the wave of erectile dysfunction treatment screening visits that were overloading our emergency departments and urgent cares. We were having plenty viagra pills for men of discussions around reimbursement for this clinic.

Do we attempt to bill insurances knowing they will likely deny, do we do a cash clinic model or do we do this as a community benefit and eat the cost?. The CMS waiver gave us hope that we would be compensated for diverting patients away from reimbursed visits to a virtual visit that is more convenient for the patient and aligns with the concept of social distancing. Realistically we viagra pills for men don’t know if we will be paid for any of this. We are holding all of the bills for at least 90 days while the industry sorts out the rules. I was excited by the reimbursement announcement because I knew we had eliminated one of the biggest direct-to-consumer virtual care barriers.

However, I was quickly brought back to reality when I was reminded that HIPAA (Health Insurance viagra pills for men Portability and Accountability Act) still existed. I had this crazy idea that during a viagra we should make it as easy as possible for people to receive virtual care and that the best way to do that was to meet the patient on the device they are most comfortable with and the application (FaceTime, Facebook, Skype, etc.) that they use every day. The problem is nearly every app the consumer uses on a daily basis is banned by HIPAA because “it’s not secure.” I’m not quite sure what a hacker stands to gain by listening into to my doctor and me talk about how my kids yet again gave me strep throat but apparently the concern is great enough to stifle the entire industry. Sure, not every health viagra pills for men care discussion is as low-key as strep throat and a patient may want to protect certain topics from being discussed over a “non-secure” app but why not let the patient decide through informed consent?. Regulators could also abandon this all-or-nothing approach and lighten regulations surrounding specific health conditions.

The idea that regulations change based on medical situation is not new. For example, in my viagra pills for men home state of Michigan, adolescents are essentially considered emancipated if it involves sexual health, mental health or substance abuse. Never mind that this same information is freely given over the phone by every office around the country daily without issue, but I digress. While my job is to innovate new pathways for care, our lawyer’s job is to protect the organization and he, along with IT security, rightfully shot down my consumer applications idea. A few days later I legitimately screamed out loud in joy when the Department of Health and viagra pills for men Human Services announced that it would use discretion on enforcing HIPAA compliance rules and specifically allowed for use of consumer applications.

The elimination of billing restrictions and HIPAA regulations changed what is possible for health care organizations to offer virtually. Unfortunately both changes are listed as temporary and will likely be removed when the viagra ends. Six days after the HIPAA changes were announced, we launched a centralized virtual clinic for any viagra pills for men patient that wanted a direct-to-consumer video visit to be screened by a provider for erectile dysfunction treatment. It allows patients to call in without a referral and most patients are on-screen within five minutes of clicking the link we text them. They don’t have to download an app, create an account or even be an established patient of our health system.

It saw over 900 patients in the first viagra pills for men 12 days it was open. That is 900 real patients that received care from a physician or advanced practice provider without risking personal exposure and without going to an already overwhelmed ED or urgent care. To date, 70 percent of the patients seen by the virtual clinic did not meet CDC testing criteria for erectile dysfunction treatment. I don’t believe we could have viagra pills for men reached even half of these patients had the consumer application restrictions been kept. A program like this almost certainly wouldn’t exist if not for the regulations being lifted and even if it did, it would have taken six to 12 months to navigate barriers and implement in normal times.

Sure, the urgency of a viagra helps but the impact of provider, patients, regulators and payors being on the same page is what fueled this fire. During the virtual clinic’s viagra pills for men first two weeks, my team turned its attention to getting over 300 providers across 60+ offices virtual so they could see their patients at home. Imagine being an immunocompromised cancer patient right now and being asked to leave your home and be exposed to other people in order to see your oncologist. Direct-to-consumer virtual care is the best way to safely care for these patients and without these temporary waivers it wouldn’t be covered by insurance even if you did navigate the clunky apps that are HIPAA compliant. Do we really think the immunocompromised cancer patient feels any more comfortable every normal flu season? viagra pills for men.

Is it any more appropriate to ask them to risk exposure to the flu than it is to erectile dysfunction treatment?. And yet we deny them this access in normal times and it quite possibly will be stripped away from them when this crisis is over. Now 300 to 400 patients per day in our health system viagra pills for men are seen virtually by their own primary care doctor or specialist for non-erectile dysfunction treatment related visits. Not a single one of these would have been reimbursed one month ago and I am highly skeptical I would have gotten approval to use the software that connects us to the patient. Lastly, recall that prior to erectile dysfunction treatment, our system had only found 250 total patients that direct-to-consumer care was value-added and wasn’t restricted by regulation or reimbursement.

erectile dysfunction treatment has been a viagra pills for men wake-up call to the whole country and health care is no exception. It has put priorities in perspective and shined a light on what is truly value-added. For direct-to-consumer virtual care it has shown us what is possible when we get out of our own way. If a regulation has to be removed to allow for care during a crisis then we must question why it exists in the first place viagra pills for men. HIPAA regulation cannot go back to its antiquated practices if we are truly going to shift the focus to patient wellness.

CMS and private payors must embrace value-added direct-to-consumer virtual care and allow patients the access they deserve. erectile dysfunction treatment has forced this industry forward, we cannot allow it to regress and be forgotten when this is over.

Overhead athletes how to buy cheap viagra online need to keep their bodies strong, and a great how to order viagra way to achieve that is by performing a regular strengthening program. With many gyms remaining closed or limiting access during social distancing, that can be even more challenging. However, there are many exercises that can be done at home with minimal equipment needs. A great program to focus on during the off season is the Thrower’s Ten program how to buy cheap viagra online that was developed with the overhead athlete in mind.

These exercises focus on the muscle groups that matter most for the overhead athlete. We use our entire body to throw a ball and the stress on the shoulder to decelerate the arm is about twice our body weight. Most of how to buy cheap viagra online this stress gets placed on the rotator cuff and scapular muscles that slow the arm down as we follow through with our throw. Weakness in these muscles can lead to problems with the shoulder and elbow joints.

Common injuries can be Little League shoulder and elbow or strains to the ulnar collateral ligaments (Tommy John). If you have dealt with pain or injuries in the past, a comprehensive evaluation by a physical therapist (PT) who focuses on treating the overhead athlete can how to buy cheap viagra online be extremely helpful in identifying areas of concern. Your PT will evaluate your strength with a dynamometer to look at any significant abnormalities between shoulders. They can also perform a video throwing analysis to look at ways to potentially reduce injury risk and improve performance.

This can how to buy cheap viagra online almost always be achieved with only a couple of visits, and the off season is a great time to start addressing areas of concern to be ready for next season or throwing during the winter. Your PT can help you develop a customized home exercise program based on your needs.

Microcirculation Endorsed by Coronary Vasomotor Disorders International Study Group’ by Vijay Kunadian from Newcastle University in the UK, and colleagues.1 While for many years our attention has been focused on coronary stenoses, growing evidence suggests that functional alterations of the coronary circulation play an important role in all clinical manifestations of ischaemic heart disease.2,3 The current contribution is an expert consensus document on ischaemia with non-obstructive coronary arteries (INOCA). Angina pectoris what does female viagra do affects ∼112 million people globally. Up to 70% of patients undergoing invasive angiography do not have obstructive coronary artery disease, more common in women than in men, and a large proportion have INOCA as a cause of their symptoms.

INOCA patients present with a wide what does female viagra do spectrum of symptoms and signs that are often misdiagnosed as non-cardiac, leading to underdiagnosis/investigation and undertreatment. INOCA can result from several mechanism including coronary vasospasm and microvascular dysfunction, and is not a benign condition. Compared with asymptomatic individuals, INOCA is associated with increased incidence of cardiovascular events, repeated hospital admissions, as well as impaired quality of life and associated increased healthcare costs. This document provides a definition of INOCA and guidance to the community on the diagnostic approach and management of INOCA based on existing evidence from research and best available clinical practice, noting what does female viagra do gaps in knowledge and potential areas for investigation.This issue then continues with a focus on acute coronary syndromes (ACS) which represent the most dramatic presentation of ischaemic heart disease.

The abrupt clinical presentation of ACS gives a strong signal of discontinuity in the natural history of atherothrombosis.4,5 While experimental models of atherogenesis have provided a growing body of information about molecular mechanisms of plaque growth, the transition from coronary stability to instability is less well understood. This issue provides novel important information in this fascinating area of cardiovascular medicine.6In a clinical research manuscript entitled ‘Long-term beta-blocker therapy and clinical outcomes after acute myocardial infarction in patients without heart what does female viagra do failure. Nationwide cohort study’, Jihoon Kim from the University School of Medicine in Seoul, South Korea and colleagues investigate the association between long-term beta-blocker therapy and clinical outcomes in patients without heart failure (HF) after acute myocardial infarction (MI).7 Between 2010 and 2015, a total of 28 970 patients who underwent coronary revascularization for acute MI with beta-blocker prescription at hospital discharge, and were event-free from death, recurrent MI, or HF for 1 year were enrolled from Korean nationwide medical insurance data. The primary outcome was all-cause death.

The secondary outcome was a composite of all-cause death, recurrent MI, or hospitalization what does female viagra do for new HF. Outcomes were compared between beta-blocker therapy for ≥1 year (n = 22707) and beta-blocker therapy for <1 year (n = 6263) using landmark analysis at 1 year after the index MI. Compared with patients receiving beta-blocker therapy for <1 year, those receiving beta-blocker therapy for ≥1 year had a significant what does female viagra do 19% lower risk of all-cause death and a significant 18% lower risk of the composite of all-cause death, recurrent MI, or hospitalization for new HF. The lower risk of all-cause death associated with persistent beta-blocker therapy was observed beyond 2 years but not beyond 3 years after MI (Figure 1).

After 3 months of dual antiplatelet therapy (DAPT) with what does female viagra do ticagrelor plus aspirin, 7119 adherent and event-free patients were randomized in a double-blind manner to ticagrelor plus placebo vs. Ticagrelor plus aspirin for 12 months. The primary outcome was Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding, while the composite of all-cause death, MI, or stroke was the key secondary outcome.

Ticagrelor monotherapy significantly reduced BARC 2, 3, or 5 bleeding by a significant 54% among NSTE-ACS patients and by a non-significant 24% among stable what does female viagra do patients (P for interaction 0.03). Rates of all-cause death, MI, or stroke were similar between treatment arms irrespective of clinical presentation.Mehran et al. Conclude that among patients with or without NSTE-ACS who have completed an initial 3-month course of DAPT following PCI with DES, ticagrelor monotherapy reduced clinically meaningful bleeding events without increasing ischaemic risk as compared with ticagrelor what does female viagra do plus aspirin. The benefits of ticagrelor monotherapy with respect to bleeding events were more pronounced in patients with NSTE-ACS.

This manuscript is accompanied by an Editorial by Robert Storey from the University of Sheffield in the UK10 who wonders if one should switch from ticagrelor monotherapy to aspirin monotherapy at 12 months or continue ticagrelor monotherapy long term, and suggests that that part of the journey remains largely unexplored.

Caused by coronary plaque erosion, account for approximately one-third of ACS cases. However, the underlying pathophysiological mechanisms as compared with ACS caused by a ruptured fibrous cap (RFC) remain largely undefined.11–14 In a clinical research article entitled ‘Differential immunological signature at the culprit site distinguishes acute coronary syndrome with intact from acute coronary syndrome with ruptured fibrous cap. Results from the prospective translational OPTICO-ACS study’, David Leistner from the Charite Universitatsmedizin Berlin in Germany and colleagues compared the microenvironment what does female viagra do of culprit lesions (CLs) with IFC vs. Those with RFC.15 The CL of 170 consecutive ACS patients was investigated by optical coherence tomography (OCT) and simultaneous immunophenotyping by flow cytometric analysis as well as by effector molecule concentration measurements across the CL.

Within the study cohort, IFC CLs caused 25% of ACS while RFC CLs caused what does female viagra do the remaining 75%, as determined and validated by two independent OCT core laboratories. IFC CLs were characterized by lower lipid content, less calcification, a thicker overlying fibrous cap, and largely localized near a coronary bifurcation as compared with RFC CLs. The microenvironment of IFC CLs demonstrated selective enrichment in both CD4+ and CD8+ T lymphocytes as compared with RFC CLs. T cell-associated extracellular circulating microvesicles were more pronounced in IFC CLs, and a significantly higher amount of CD8+ T lymphocytes was detectable in thrombi aspirated from IFC CLs as compared with RFC CLs what does female viagra do.

Furthermore, IFC CLs showed significantly increased levels of the T-cell effector molecules granzyme A (+22%), perforin (+59%), and granulysin (+75%) as compared with RFC CLs. Endothelial cells subjected to culture in disturbed laminar flow conditions to simulate coronary flow near a bifurcation demonstrated an enhanced what does female viagra do adhesion of CD8+ T cells. Finally, both CD8+ T cells and their cytotoxic effector molecules caused endothelial cell death, a key potential pathophysiological mechanism in IFC CLs.Thus, the OPTICO-ACS study emphasizes a novel mechanism in the pathogenesis of IFC CLs, favouring participation of the adaptive immune system, particularly CD8+ T cells and their effector molecules. The manuscript is accompanied by an Editorial by Giovanna Liuzzo and colleagues (myself included) from the Catholic University16 who conclude that we are learning a lot about plaque erosion but we should not forget the words of Winston Churchill.

€˜Now this is not what does female viagra do the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning.’Balance between inflammatory and reparative leucocytes allows optimal healing after MI.17 In a clinical research article ‘Molecular imaging-guided repair after acute myocardial infarction by targeting the chemokine receptor CXCR4’, what does female viagra do Annika Hess from the Hannover Medical School in Germany and colleagues aimed to characterize infarct chemokine CXC receptor 4 (CXCR4) expression using positron emission tomography (PET) and establish its relationship to cardiac outcome. The authors tested whether image-guided early CXCR4-directed therapy attenuates chronic dysfunction.18 A total of 180 mice underwent coronary ligation or sham surgery and serial PET imaging over 7 days.

Infarct CXCR4 content was significantly higher over 3 days after MI compared with sham, confirmed by flow cytometry and histopathology. Mice that died of left ventricular (LV) rupture exhibited persistent inflammation at 3 days compared with what does female viagra do survivors. Higher CXCR4 signal at 1 and 3 days independently predicted significantly worse functional outcome at 6 weeks assessed by cardiac magnetic resonance. Following the imaging time-course, mice were treated what does female viagra do with AMD3100, a CXCR4 blocker.

CXCR4 blockade at 3 days significantly lowered LV rupture incidence vs. Untreated MI (8% vs. 25%), and what does female viagra do significantly improved contractile function at 6 weeks. CXCR4 blockade at 7 days failed to improve the outcome.

Flow cytometry analysis revealed lower LV neutrophil what does female viagra do and Ly6C high monocyte content after CXCR4 blockade at 3 days. A total of 50 patients underwent CXCR4 PET imaging and functional assessment early after MI. CXCR4 expression correlated with contractile function.Hess and colleagues conclude that PET imaging identifies early CXCR4 up-regulation which predicts acute rupture and chronic contractile dysfunction. Imaging-guided CXCR4 inhibition accelerates inflammatory resolution and improves what does female viagra do outcome.

This supports a molecular imaging-based theranostic approach to guide therapy after MI. The manuscript is accompanied by an Editorial by Christian Weber from the Ludwig-Maximilians-Universität in what does female viagra do Munich, Germany and colleagues.19 The authors point out that the study of Hess et al. Building on the virtues of molecular PET imaging for non-invasive analysis of biomarker expression within injured tissue, in a pre-clinical as well as in a clinical setting, demonstrates the value of CXCR4 PET imaging in identifying the best time point of anti-inflammatory treatment by CXCR4 antagonism with respect to chronic cardiac function.In a clinical review article entitled ‘Management of non-culprit coronary plaques in patients with acute coronary syndrome’, Rocco Montone from the Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome, Italy, and colleagues (including myself) note that ∼50% of patients with ST-segment elevation myocardial infarction (STEMI) have multivessel coronary artery disease, a condition associated with an increased incidence of recurrent ischaemic events and higher mortality.20,21 Based on recent evidence, a strategy of staged PCI of obstructive non-culprit lesions should be considered the gold standard for the management of these patients.22 However, several issues remain unresolved.

Indeed, what what does female viagra do the optimal timing of staged PCI is has not been completely defined. Moreover, assessment of intermediate non-culprit lesions still represents a clinical conundrum, as pressure-wire indexes do not seem able to correctly identify those patients in whom deferral is safe. Intracoronary imaging may help what does female viagra do to identify untreated non-culprit lesions containing vulnerable plaques that may portend a higher risk of future cardiovascular events. However, there are hitherto no studies demonstrating that preventive PCI of vulnerable plaques or more intensive pharmacological treatment is associated with an improved clinical outcome.

In this review, the authors discuss the recent evolving concepts about management of non-culprit plaques in STEMI patients, proposing a diagnostic and therapeutic algorithm to guide physicians in clinical practice. They also underscore the several knowledge what does female viagra do gaps which need to be addressed in future studies.This issue is also complemented by two Discussion Forum contributions. In a contribution entitled ‘Extracorporeal cardiopulmonary resuscitation in out-of-hospital cardiac arrest in relation to organ donation’, Stefan Roest from the Erasmus MC in Amsterdam, the Netherlands and colleagues comment on the recent publication entitled ‘Extracorporeal cardiopulmonary resuscitation in out-of-hospital cardiac arrest.

Journals.permissions@oup.com.The Ten ‘Commandments’(1) DiagnosisChest discomfort without persistent ST-segment elevation (NSTE-ACS) is the leading symptom initiating the diagnostic and therapeutic cascade. The correlated pathology at the myocardial level is cardiomyocyte necrosis, measured by troponin release, or, less frequently, myocardial ischaemia without cell damage (unstable angina).(2) Troponin assaysHigh-sensitivity troponin assay (hs-cTn) measurements are recommended over less sensitive ones. However, many cardiac pathologies other than MI may also result in cardiac troponin elevations.(3) Rapid ‘rule-in’ and ‘rule-out’ algorithmsIt is recommended to use the 0 h/1 h algorithm (best option) or the 0 h/2 h algorithm. Used in conjunction with clinical and ECG findings, the 0 h/1 h and 0 h/2 h hs-cTn algorithms allow identification of appropriate candidates for early discharge and outpatient management.(4) Ischaemic/bleeding risk assessmentInitial hs-cTn levels add prognostic information in terms of short- and long-term mortality to clinical and ECG variables.

The Global Registry of Acute Coronary Events (GRACE) risk score is superior to (subjective) physician assessment for the occurrence of death or MI. The Academic Research Consortium-High Bleeding Risk may be used to assess the bleeding risk.(5) Non-invasive imagingEven after the rule-out of MI, elective non-invasive or invasive imaging may be indicated according to clinical assessment. Coronary computed tomography angiography or stress imaging may be options based on risk assessment.(6) Risk stratification for an invasive approachAn early routine invasive approach within 24 h of admission is recommended for Non ST segment elevation myocardial infarction (NSTEMI) based on hs-cTn measurements, GRACE risk score >140, and dynamic new or presumably new ST-segment changes. Immediate invasive angiography is required in highly unstable patients according to hemodynamic status, arrhythmias, acute heart failure, or persistent chest pain.

In all other clinical presentations, a selective invasive approach may be performed according to non-invasive testing or clinical risk assessment.(7) Revascularization strategiesRadial access is recommended as the preferred approach in NSTE-ACS patients undergoing invasive assessment. Percutaneous coronary intervention of the culprit lesion is the treatment of choice. In multivessel disease, timing and completeness of revascularization should be decided according to the functional relevance of stenoses, age, general patient condition, comorbidities, and left ventricular function.(8) MINOCAMyocardial infarction with non-obstructive coronary arteries incorporates a heterogeneous group of underlying causes that may involve both coronary and non-coronary pathological conditions. Cardiac magnetic resonance imaging is one of the key diagnostic tools as it allows to identify the underlying cause in the majority of patients.(9) Post-treatment antiplatelet therapyDual antiplatelet therapy consisting of a potent P2Y12 receptor inhibitor in addition to aspirin is generally recommended for 12 months unless there are contraindications.

Dual antiplatelet therapy duration can be shortened (<12 months), extended (>12 months), or modified by switching DAPT or de-escalation depending on individual clinical judgement driven by ischaemic and bleeding risk.(10) Triple antithrombotic therapyNon-vitamin K oral anticoagulants (NOACs) are preferred over vitamin K antagonists in patients undergoing PCI with an indication for long-term oral anticoagulation. Dual antithrombotic therapy with a NOAC and single antiplatelet therapy is recommended as the default strategy up to 12 months after a short period of up to 1 week of TAT. Triple antithrombotic therapy may be prolonged up to 1 month when the ischaemic risk outweighs the bleeding risk..

Microcirculation Endorsed by Coronary Vasomotor Disorders International Study Group’ by Vijay Kunadian from Newcastle University in the UK, and colleagues.1 While for many years our attention has been focused on coronary stenoses, growing evidence suggests that functional alterations of the coronary circulation play an important role in all clinical manifestations of ischaemic heart disease.2,3 The current contribution is an expert consensus document on ischaemia with non-obstructive coronary arteries (INOCA). Angina pectoris affects ∼112 million people globally how to buy cheap viagra online.

Up to 70% of patients undergoing invasive angiography do not have obstructive coronary artery disease, more common in women than in men, and a large proportion have INOCA as a cause of their symptoms. INOCA patients present with a wide spectrum of symptoms and signs how to buy cheap viagra online that are often misdiagnosed as non-cardiac, leading to underdiagnosis/investigation and undertreatment. INOCA can result from several mechanism including coronary vasospasm and microvascular dysfunction, and is not a benign condition.

Compared with asymptomatic individuals, INOCA is associated with increased incidence of cardiovascular events, repeated hospital admissions, as well as impaired quality of life and associated increased healthcare costs. This document provides a definition of INOCA and guidance to the community on the diagnostic approach and management of INOCA based on existing evidence from research and best available clinical practice, noting gaps in knowledge and potential areas for investigation.This issue then continues with a focus on acute coronary how to buy cheap viagra online syndromes (ACS) which represent the most dramatic presentation of ischaemic heart disease. The abrupt clinical presentation of ACS gives a strong signal of discontinuity in the natural history of atherothrombosis.4,5 While experimental models of atherogenesis have provided a growing body of information about molecular mechanisms of plaque growth, the transition from coronary stability to instability is less well understood.

This issue provides novel important information in this fascinating area of cardiovascular medicine.6In a clinical research manuscript entitled how to buy cheap viagra online ‘Long-term beta-blocker therapy and clinical outcomes after acute myocardial infarction in patients without heart failure. Nationwide cohort study’, Jihoon Kim from the University School of Medicine in Seoul, South Korea and colleagues investigate the association between long-term beta-blocker therapy and clinical outcomes in patients without heart failure (HF) after acute myocardial infarction (MI).7 Between 2010 and 2015, a total of 28 970 patients who underwent coronary revascularization for acute MI with beta-blocker prescription at hospital discharge, and were event-free from death, recurrent MI, or HF for 1 year were enrolled from Korean nationwide medical insurance data. The primary outcome was all-cause death.

The secondary outcome was how to buy cheap viagra online a composite of all-cause death, recurrent MI, or hospitalization for new HF. Outcomes were compared between beta-blocker therapy for ≥1 year (n = 22707) and beta-blocker therapy for <1 year (n = 6263) using landmark analysis at 1 year after the index MI. Compared with patients receiving beta-blocker therapy for <1 year, those receiving beta-blocker therapy for ≥1 year had a significant 19% lower risk of all-cause death and a significant 18% lower risk of the how to buy cheap viagra online composite of all-cause death, recurrent MI, or hospitalization for new HF.

The lower risk of all-cause death associated with persistent beta-blocker therapy was observed beyond 2 years but not beyond 3 years after MI (Figure 1).

The manuscript is accompanied by an Editorial by Rafael Harari and Sripal Bangalore from the New York University School of Medicine in the USA, who conclude that a drug that has been widely used clinically for over half a century is now in urgent need of reappraisal from contemporary trials.8In a clinical research article entitled ‘Ticagrelor alone versus ticagrelor plus aspirin following percutaneous coronary intervention in patients with non-ST-segment elevation acute how to buy cheap viagra online coronary syndromes. TWILIGHT-ACS’, Roxana Mehran from Mount Sinai School of Medicine in New York, USA and colleagues determined the effect of ticagrelor monotherapy on clinically relevant bleeding and major ischaemic events in relation to clinical presentation with and without non-ST elevation acute coronary syndromes (NSTE-ACS) among patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES).9 The authors conducted a pre-specified subgroup analysis of The Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention (TWILIGHT) trial, which enrolled 9006 patients with high-risk features undergoing PCI with DES. After 3 months of dual antiplatelet therapy (DAPT) with ticagrelor plus how to buy cheap viagra online aspirin, 7119 adherent and event-free patients were randomized in a double-blind manner to ticagrelor plus placebo vs.

Ticagrelor plus aspirin for 12 months. The primary outcome was Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding, while the composite of all-cause death, MI, or stroke was the key secondary outcome. Ticagrelor monotherapy significantly reduced BARC 2, 3, or 5 bleeding by a how to buy cheap viagra online significant 54% among NSTE-ACS patients and by a non-significant 24% among stable patients (P for interaction 0.03).

Rates of all-cause death, MI, or stroke were similar between treatment arms irrespective of clinical presentation.Mehran et al. Conclude that among patients with or without NSTE-ACS who have completed an initial 3-month course of DAPT following PCI with DES, ticagrelor monotherapy reduced clinically meaningful bleeding events without increasing ischaemic risk as compared how to buy cheap viagra online with ticagrelor plus aspirin. The benefits of ticagrelor monotherapy with respect to bleeding events were more pronounced in patients with NSTE-ACS.

This manuscript is accompanied by an Editorial by Robert Storey from the University of Sheffield in the UK10 who wonders if one should switch from ticagrelor monotherapy to aspirin monotherapy at 12 months or continue ticagrelor monotherapy long term, and suggests that that part of the journey remains largely unexplored.

Since acute coronary syndromes with intact fibrous cap-lesion were often located at bifurcations, endothelial cells were subjected to culture in disturbed laminar flow how to buy cheap viagra online conditions (C), i.e. To simulate coronary flow near a bifurcation, demonstrated an enhanced adhesion of CD8+ T cells.

Finally, both CD8+ T cells and their cytotoxic effector molecules caused endothelial cell death, a key pathophysiological mechanism in acute coronary syndromes with intact fibrous cap (from Leistner DM, Kränkel N, Meteva D, Abdelwahed YS, Seppelt C, Stähli BE, Rai H, Skurk C, Lauten A, Mochmann H-C, Fröhlich G, Rauch-Kröhnert U, Flores E, Riedel M, Sieronski L, Kia S, Strässler E, Haghikia A, Dirks F, Steiner JK, Mueller DN, Volk H-D, Klotsche J, Joner M, Libby P, Landmesser U.

Results from the prospective translational OPTICO-ACS study.

See pages 3549–3560).ACS how to buy cheap viagra online with an intact fibrous cap (IFC), i.e. Caused by coronary plaque erosion, account for approximately one-third of ACS cases. However, the underlying pathophysiological mechanisms as compared with ACS caused by a ruptured fibrous cap (RFC) remain largely undefined.11–14 In a clinical research article entitled ‘Differential immunological signature at the culprit site distinguishes acute coronary syndrome with intact from acute coronary syndrome with ruptured fibrous cap.

Results from the prospective translational OPTICO-ACS study’, David Leistner from the Charite Universitatsmedizin how to buy cheap viagra online Berlin in Germany and colleagues compared the microenvironment of culprit lesions (CLs) with IFC vs. Those with RFC.15 The CL of 170 consecutive ACS patients was investigated by optical coherence tomography (OCT) and simultaneous immunophenotyping by flow cytometric analysis as well as by effector molecule concentration measurements across the CL. Within the study cohort, IFC CLs caused 25% of ACS while RFC CLs caused the remaining 75%, as determined how to buy cheap viagra online and validated by two independent OCT core laboratories.

IFC CLs were characterized by lower lipid content, less calcification, a thicker overlying fibrous cap, and largely localized near a coronary bifurcation as compared with RFC CLs. The microenvironment of IFC CLs demonstrated selective enrichment in both CD4+ and CD8+ T lymphocytes as compared with RFC CLs. T cell-associated extracellular circulating microvesicles were more pronounced in IFC CLs, and a significantly higher amount of CD8+ T lymphocytes was detectable in thrombi aspirated how to buy cheap viagra online from IFC CLs as compared with RFC CLs.

Furthermore, IFC CLs showed significantly increased levels of the T-cell effector molecules granzyme A (+22%), perforin (+59%), and granulysin (+75%) as compared with RFC CLs. Endothelial cells subjected to culture in disturbed laminar flow conditions to simulate coronary flow near a bifurcation demonstrated how to buy cheap viagra online an enhanced adhesion of CD8+ T cells. Finally, both CD8+ T cells and their cytotoxic effector molecules caused endothelial cell death, a key potential pathophysiological mechanism in IFC CLs.Thus, the OPTICO-ACS study emphasizes a novel mechanism in the pathogenesis of IFC CLs, favouring participation of the adaptive immune system, particularly CD8+ T cells and their effector molecules.

It is not even the beginning of the end.

But it is, perhaps, the end of the beginning.’Balance between inflammatory and reparative leucocytes allows optimal healing after MI.17 In a clinical research article ‘Molecular imaging-guided repair after acute myocardial infarction by targeting the chemokine how to buy cheap viagra online receptor CXCR4’, Annika Hess from the Hannover Medical School in Germany and colleagues aimed to characterize infarct chemokine CXC receptor 4 (CXCR4) expression using positron emission tomography (PET) and establish its relationship to cardiac outcome. The authors tested whether image-guided early CXCR4-directed therapy attenuates chronic dysfunction.18 A total of 180 mice underwent coronary ligation or sham surgery and serial PET imaging over 7 days. Infarct CXCR4 content was significantly higher over 3 days after MI compared with sham, confirmed by flow cytometry and histopathology.

Mice that died of how to buy cheap viagra online left ventricular (LV) rupture exhibited persistent inflammation at 3 days compared with survivors. Higher CXCR4 signal at 1 and 3 days independently predicted significantly worse functional outcome at 6 weeks assessed by cardiac magnetic resonance. Following the imaging time-course, mice were treated with AMD3100, how to buy cheap viagra online a CXCR4 blocker.

CXCR4 blockade at 3 days significantly lowered LV rupture incidence vs. Untreated MI (8% vs. 25%), and how to buy cheap viagra online significantly improved contractile function at 6 weeks.

CXCR4 blockade at 7 days failed to improve the outcome. Flow cytometry analysis revealed lower LV neutrophil and Ly6C high how to buy cheap viagra online monocyte content after CXCR4 blockade at 3 days. A total of 50 patients underwent CXCR4 PET imaging and functional assessment early after MI.

CXCR4 expression correlated with contractile function.Hess and colleagues conclude that PET imaging identifies early CXCR4 up-regulation which predicts acute rupture and chronic contractile dysfunction. Imaging-guided CXCR4 inhibition accelerates inflammatory resolution and improves outcome how to buy cheap viagra online. This supports a molecular imaging-based theranostic approach to guide therapy after MI.

The manuscript is accompanied by an Editorial by Christian how to buy cheap viagra online Weber from the Ludwig-Maximilians-Universität in Munich, Germany and colleagues.19 The authors point out that the study of Hess et al. Building on the virtues of molecular PET imaging for non-invasive analysis of biomarker expression within injured tissue, in a pre-clinical as well as in a clinical setting, demonstrates the value of CXCR4 PET imaging in identifying the best time point of anti-inflammatory treatment by CXCR4 antagonism with respect to chronic cardiac function.In a clinical review article entitled ‘Management of non-culprit coronary plaques in patients with acute coronary syndrome’, Rocco Montone from the Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome, Italy, and colleagues (including myself) note that ∼50% of patients with ST-segment elevation myocardial infarction (STEMI) have multivessel coronary artery disease, a condition associated with an increased incidence of recurrent ischaemic events and higher mortality.20,21 Based on recent evidence, a strategy of staged PCI of obstructive non-culprit lesions should be considered the gold standard for the management of these patients.22 However, several issues remain unresolved.

Indeed, what how to buy cheap viagra online the optimal timing of staged PCI is has not been completely defined. Moreover, assessment of intermediate non-culprit lesions still represents a clinical conundrum, as pressure-wire indexes do not seem able to correctly identify those patients in whom deferral is safe. Intracoronary imaging may help to identify untreated non-culprit lesions containing vulnerable plaques that may portend how to buy cheap viagra online a higher risk of future cardiovascular events.

However, there are hitherto no studies demonstrating that preventive PCI of vulnerable plaques or more intensive pharmacological treatment is associated with an improved clinical outcome. In this review, the authors discuss the recent evolving concepts about management of non-culprit plaques in STEMI patients, proposing a diagnostic and therapeutic algorithm to guide physicians in clinical practice. They also how to buy cheap viagra online underscore the several knowledge gaps which need to be addressed in future studies.This issue is also complemented by two Discussion Forum contributions.

Journals.permissions@oup.com.The Ten ‘Commandments’(1) DiagnosisChest discomfort without persistent ST-segment elevation (NSTE-ACS) is the leading symptom initiating the diagnostic and therapeutic cascade. The correlated pathology at the myocardial level is cardiomyocyte necrosis, measured by troponin release, or, less frequently, myocardial ischaemia without cell damage (unstable angina).(2) Troponin assaysHigh-sensitivity troponin assay (hs-cTn) measurements are recommended over less sensitive ones. However, many cardiac pathologies other than MI may also result in cardiac troponin elevations.(3) Rapid ‘rule-in’ and ‘rule-out’ algorithmsIt is recommended to use the 0 h/1 h algorithm (best option) or the 0 h/2 h algorithm.

Used in conjunction with clinical and ECG findings, the 0 h/1 h and 0 h/2 h hs-cTn algorithms allow identification of appropriate candidates for early discharge and outpatient management.(4) Ischaemic/bleeding risk assessmentInitial hs-cTn levels add prognostic information in terms of short- and long-term mortality to clinical and ECG variables. The Global Registry of Acute Coronary Events (GRACE) risk score is superior to (subjective) physician assessment for the occurrence of death or MI. The Academic Research Consortium-High Bleeding Risk may be used to assess the bleeding risk.(5) Non-invasive imagingEven after the rule-out of MI, elective non-invasive or invasive imaging may be indicated according to clinical assessment.

Coronary computed tomography angiography or stress imaging may be options based on risk assessment.(6) Risk stratification for an invasive approachAn early routine invasive approach within 24 h of admission is recommended for Non ST segment elevation myocardial infarction (NSTEMI) based on hs-cTn measurements, GRACE risk score >140, and dynamic new or presumably new ST-segment changes. Immediate invasive angiography is required in highly unstable patients according to hemodynamic status, arrhythmias, acute heart failure, or persistent chest pain. In all other clinical presentations, a selective invasive approach may be performed according to non-invasive testing or clinical risk assessment.(7) Revascularization strategiesRadial access is recommended as the preferred approach in NSTE-ACS patients undergoing invasive assessment.

Percutaneous coronary intervention of the culprit lesion is the treatment of choice. In multivessel disease, timing and completeness of revascularization should be decided according to the functional relevance of stenoses, age, general patient condition, comorbidities, and left ventricular function.(8) MINOCAMyocardial infarction with non-obstructive coronary arteries incorporates a heterogeneous group of underlying causes that may involve both coronary and non-coronary pathological conditions. Cardiac magnetic resonance imaging is one of the key diagnostic tools as it allows to identify the underlying cause in the majority of patients.(9) Post-treatment antiplatelet therapyDual antiplatelet therapy consisting of a potent P2Y12 receptor inhibitor in addition to aspirin is generally recommended for 12 months unless there are contraindications.

Dual antiplatelet therapy duration can be shortened (<12 months), extended (>12 months), or modified by switching DAPT or de-escalation depending on individual clinical judgement driven by ischaemic and bleeding risk.(10) Triple antithrombotic therapyNon-vitamin K oral anticoagulants (NOACs) are preferred over vitamin K antagonists in patients undergoing PCI with an indication for long-term oral anticoagulation. Dual antithrombotic therapy with a NOAC and single antiplatelet therapy is recommended as the default strategy up to 12 months after a short period of up to 1 week of TAT. Triple antithrombotic therapy may be prolonged up to 1 month when the ischaemic risk outweighs the bleeding risk..

Can viagra cause a stroke

IntroductionThere has been considerable interest in elucidating the contribution of genetic factors to the development of common can viagra cause a stroke diseases and using this information http://markolewis.com/ventolin-street-price for better prediction of disease risk. The common disease common variant hypothesis predicts that variants that are common in the population play a role in disease susceptibility.1 Genome-wide association studies (GWAS) using single nucleotide polymorphism (SNP) arrays were developed can viagra cause a stroke as a mechanism by which to investigate these genetic factors and it was hoped this would lead to identification of variants associated with disease risk and subsequent development of predictive tests. Variants identified as associated with particular traits by these studies, for the large part, are SNPs that individually have a minor effect on disease risk and hence, by themselves, cannot be reliably used in disease prediction. Looking at the aggregate impact of these SNPs in the form of a polygenic score can viagra cause a stroke (PGS) appeared to be one possible means of using this information to predict disease.2 It is thought this will be of benefit as our genetic make-up is largely stable from birth and dictates a ‘baseline risk’ on which external influences act and modulate.

Therefore, PGS are a potential mechanism to act as a risk predictor by capturing information on this genetic liability.The use of PGS as a predictive biomarker is being explored in a number of different disease areas, including cancer,3 4 psychiatric disorders,5–7 metabolic disorders (diabetes,8 obesity9) and coronary artery disease (CAD).10 The proposed applications range from aiding disease diagnosis, informing selection of therapeutic interventions, improvement of risk prediction, informing disease screening and, on a personal level, informing life planning. Therefore, genetic risk information in the form of a PGS is considered to have potential in informing both clinical and individual-level decision-making.Recent advances in statistical techniques, improved computational power and the availability of large data sets have led to rapid developments in this area over can viagra cause a stroke the past few years. This has resulted in a variety of approaches to construction of models for score calculation and the investigation of these scores for prediction of common diseases.11 Several review articles aimed at researchers with a working knowledge of this field have been produced.6 11–17 In this article, we provide an overview of the key aspects of PGS construction to assist clinicians and researchers in other areas of academia to gain an understanding of the processes involved in score construction. We also consider the implications of evolving methodologies for the development of applications of PGS in healthcare.Evolution in polygenic model construction methodologiesTerminology with respect to PGS has evolved can viagra cause a stroke over time, reflecting evolving approaches and methodology.

Other terms include PGS, polygenic risk score, polygenic load, genotype score, genetic burden, polygenic hazard score, genetic risk score (GRS), metaGRS and allelic risk score. Throughout this article we use the terms polygenic models to refer to the method used to calculate an output in the form can viagra cause a stroke of a PGS. Different polygenic models can be used to calculate a PGS and analysis of these scores can be used to examine associations with particular markers or to predict an individuals risk of diseases.12Usual practice in calculating PGS is as a weighted sum of a number of risk alleles carried by an individual, where the risk alleles and their weights are defined by SNPs and their measured effects (figure 1).11 Polygenic models have been constructed using a few, hundreds or thousands of SNPs, and more recently SNPs across the whole genome. Consequently, determining which SNPs to include and the disease-associated weighting to assign to SNPs are important aspects of model construction (figure 2).18 These aspects are influenced by available genotype can viagra cause a stroke data and effect size estimates as well as the methodology employed in turning this information into model parameters (ie, weighted SNPs).Polygenic score calculation.

This calculation aggregates the SNPs and their weights selected for a polygenic score. Common diseases are thought to be influenced by many genetic can viagra cause a stroke variants with small individual effect sizes, such that meaningful risk prediction necessitates examining the aggregated impact of these multiple variants including their weightings.

The model that performs best (as determined by one or more measures) is then selected can viagra cause a stroke for validation in the external data set. GWAS, genome-wide association studies.Changes in data availability over time have had an impact on the approach taken in SNP selection and weighting.

Early studies to identify variants associated with common diseases took the form of candidate gene studies can viagra cause a stroke. The small size of candidate gene studies, the limitation of technologies available for genotyping and stringent significance thresholds meant that these studies investigated fewer variants and those that were identified with disease associations had relatively large effect sizes.19 Taken together, this meant that a relatively small number of variants were available for consideration for inclusion in a polygenic model.20 21 Furthermore, weighting parameters for these few variants were often simplistic, such as counts of the number of risk alleles carried, ignoring their individual effect sizes.16The advent of GWAS enabled assessment of SNPs across the genome, leading to the identification of a larger number of disease-associated variants and therefore more variants suitable for inclusion in a polygenic model. In addition, the increasing number of individuals in the association studies meant that the power of these studies increased, allowing for more precise estimates of effect sizes.19 Furthermore, some theorised that lowering stringent significance thresholds set for SNP–trait associations could also identify SNPs that might play a part in disease risk.11 16 This resulted in more options with respect to polygenic model parameters of SNPs to include and weights to assign can viagra cause a stroke to them. However, the inclusion of more SNPs and direct application of GWAS effect sizes as a weighting parameter does not always equate to better predictive performance.4 16 This is because GWAS do not provide perfect information with respect to the causal SNP, the effect sizes or the number of SNPs that contribute to the trait.

Therefore, different methods have can viagra cause a stroke been developed to address these issues and optimise predictive performance of the score. Current common practice is to construct models with different iterations of SNPs and weighting, with assessment of the performance of each to identify the optimum configuration of SNPs and their weights (figure 2).Methods used in SNP selection and weighting assignmentSome methods of model development will initially involve selection of SNPs followed by optimisation of weighting, whereas others may involve optimisation of weightings for all SNPs that have been genotyped using their overall GWAS effect sizes, the linkage disequilibrium (LD) and an estimate of the proportion of SNPs that are expected to contribute to the risk.22LD is the phenomenon where some SNPs are coinherited more frequently with other SNPs due to their close proximity on the genome. Segments with strong LD between SNPs are can viagra cause a stroke referred to as haplotype blocks. This phenomenon means that GWAS often identify multiple SNPs in the same haplotype block associated with disease and the true causal SNP is not known.

As models have started to assess more SNPs, careful consideration is required can viagra cause a stroke to take into account possible correlation between SNPs as a result of this phenomenon. Correlation between SNPs can lead to double counting of SNPs and association redundancy, where can viagra cause a stroke multiple SNPs in a region of LD are identified as being associated with the outcome. This can lead to reduction in the predictive performance of the model. Therefore, processes for filtering SNPs and using one SNP can viagra cause a stroke (tag SNP) to act as a marker in an area of high LD, through LD thinning, were developed.

Through these processes SNPs correlated with other SNPs in a block are removed, by either pruning or clumping. Pruning ignores p value thresholds and ‘eliminates’ SNPs by a process of iterative can viagra cause a stroke comparison between a pair of SNPs to assess if they are correlated, and subsequently could remove SNPs that are deemed to have evidence of association. Clumping (also known as informed pruning) is guided by GWAS p values and chooses the most significant SNP, therefore keeping the most significant SNP within a block.23 This is all done with the aim of pinpointing relatively small areas of the genome that contribute to risk of the trait. Different significance thresholds may be used to select SNPs from this subgroup for inclusion in models.Poor performance of a model can result from imperfect tagging with the underlying causal SNP.16 This is because the causal SNP that is associated with disease might not be in LD with the tag SNP that is in the model can viagra cause a stroke but is in LD with another SNP which is not in the model.

This particularly occurs where the LD and variant frequency differs between population groups.24 An alternate approach to filter SNPs is stepwise regression where SNPs are selected based on how much the SNPs improve the model’s performance. This is a statistical approach and can viagra cause a stroke does not consider the impact of LD or effect size.As described above, early studies used simple weighting approaches or directly applied effect sizes from GWAS as weighting parameters for SNPs. However, application of effect sizes as a weighting parameter directly from a GWAS may not be optimal, due to differences in the population that the GWAS was conducted in and the target population. Also as described above, LD and the fact that not all can viagra cause a stroke SNPs may contribute to the trait mean that these effect sizes from GWAS are imperfect estimates.

Therefore, methods have been developed that adjust effect size estimates from GWAS using statistical techniques which make assumptions about factors such as the number of causal SNPs, level of LD between SNPs or knowledge of their potential function to better reflect their impact on a trait. Numerous statistical methodologies have been developed to improve weighting with a view to enhancing the discriminative power of a PGS.25 26 Examples of some methodological approaches are LDpred,22 winner’s curse correction,23 empirical Bayes estimation,27 shrinkage regression (Lasso),28 linear mixed can viagra cause a stroke models,29 with more being developed or tested. An additional improvement on the methods is to embed non-genetic information (eg, age-specific ORs).6 Determination of which methodology or hybrid of methodologies is most appropriate for various settings and conditions is continuously being explored and is evolving with new statistical approaches developing at a rapid pace.In summary, model development has evolved in an attempt to gain the most from available GWAS data and address some of the issues that arise due to working with data sets which cannot be directly translated into parameters for prediction models. The different approaches taken in SNP selection and weighting, and the impact on the predictive performance of a model are can viagra cause a stroke important to consider when assessing different models.

This is because different approaches to PGS modelling can achieve the same or a similar level of prediction. From a health system implementation perspective, particular approaches may be preferred following practical considerations and trade-offs between obtaining genotype can viagra cause a stroke data, processes for score construction and model performance. In addition, the degree to which these parameters need to be optimised will also be impacted by the input data and validation data set, and the quality control procedures that need to be applied to can viagra cause a stroke these data sets.12Sources of input data for score constructionKey to the development of a polygenic model is the availability of data sets that can provide input parameters for model construction. Genotype data used in model construction can either be available as raw GWAS data or provided as GWAS summary statistics.

Data in the raw can viagra cause a stroke format are individual-level data from a SNP array and may not have undergone basic quality control such as assessment of missingness, sex discrepancy checks, deviation from Hardy-Weinberg equilibrium, heterozygosity rate, relatedness or assessment for outliers.30 31 Availability of raw GWAS data allows for different polygenic models to be developed because of the richness of the data, however computational issues arise because of the size of the data sets. Data based on genome sequencing, as opposed to SNP arrays, could also be used in model construction. There have been limited studies of PGS developed from this form of data due to limitations in data availability, can viagra cause a stroke which is mainly due to cost restraints.15 32 Individual-level genomic data are also often not available to researchers due to privacy concerns.Due to these issues, the focus of polygenic model development has therefore been on using well-powered GWAS summary statistics.33 These are available from open access repositories and contain summary information such as the allele positions, ORs, CIs and allele frequency, without containing confidential information on individuals. These data sets have usually been through the basic quality control measures mentioned above.

There are, however, no standards for publicly available files, meaning some further processing steps may be required, in can viagra cause a stroke particular when various data sets are combined for a meta-analysis. Quality control on summary statistics is only possible if information such as missing genotype rate, minor allele frequency, Hardy-Weinberg equilibrium failures and non-Mendelian transmission rates is provided.12Processing of GWAS data may include additional quality control steps, imputation and filtering of the SNP information, which can be done at the level of genotype or summary statistics data. SNP arrays used in GWAS only have common SNPs represented on them as can viagra cause a stroke they rely on LD between SNPs to cover the entire genome. As described above, one tag SNP on the array can represent many other SNPs.

Imputation of SNPs is common in GWAS and describes the process of predicting genotypes that have not been directly genotyped but are statistically inferred (imputed) based on haplotype blocks from a reference can viagra cause a stroke sequence.33–35 Often association tests between the imputed SNPs and trait are repeated. As genotype imputation requires individual-level data, researchers have proposed summary statistics imputation as a mechanism to infer the association between untyped SNPs and a trait. The performance of imputation has been evaluated and shown that, with certain limitations, summary statistics imputation is an efficient and cost-effective methodology to identify loci associated with traits when compared with imputation done on can viagra cause a stroke genotypes.36An alternative source of input data for the selection of SNPs and their weightings is through literature or in existing databases, where already known trait-associated SNPs and their effect sizes are used as the input parameters in model development. A number of studies have taken this approach37 38 and it is possible to use multiple sources when developing various polygenic models and establishing the preferred parameters to use.Currently, there does not appear to be one methodology that works across all contexts and traits, each trait will need to be assessed to determine which method is the most suitable for the trait being evaluated.

For example, four different polygenic model construction can viagra cause a stroke strategies were explored for three skin cancer subtypes4 by using data on SNPs and their effect sizes from different sources, such as the latest GWAS meta-analysis results, the National Human Genome Research Institute (NHGRI) EBI GWAS catalogue, UK Biobank GWAS summary statistics with different thresholds and GWAS summary statistics with LDpred. In this setting for basal cell carcinoma and melanoma, the meta-analysis and catalogue-derived models were found to perform similarly but that the latter was ultimately used as it included more SNPs. For squamous cell carcinoma the meta-analysis-derived model performed can viagra cause a stroke better than the catalogue-derived model. This demonstrates can viagra cause a stroke how each disease subtype, model construction strategy and data set can have their own limitations and advantages.Knowledge of the sources of input data and its subsequent use in model development is important in understanding the limitations of available models.

Models that are developed using data sets that reflect the population in which prediction is to be carried out will perform better. For example, can viagra cause a stroke data collected from a symptomatic or high-risk population may not be suitable as an input data set for the development of a polygenic model that will be used for disease prediction in the general population. Large GWAS studies were previously focused on high-risk individuals, such as patients with breast cancer with a strong family history or known pathogenic variants in BRCA1 or BRCA2. These studies would not be suitable for the development of PGS for use in the general can viagra cause a stroke population but can inform risk assessment in high-risk individuals.

The source of the data for SNP selection and weighting also has implications for downstream uses and validation. For example, variant frequency and LD patterns can vary between populations and this can translate to poor performance of the polygenic model if the external validation population is different from that of the input data set.39–41 Furthermore, the power and validity of polygenic analyses are can viagra cause a stroke influenced by the input data sources.12 42From a model to a scorePGS can be calculated using one of the methodologies discussed above. The resulting PGS units of measurement depend on which measurement is used for the weighting.12 For example, the weightings may have been calculated based on logOR for discrete traits or linear regression coefficient (β/beta) in continuous traits from univariate regression tests carried out in the GWAS. The resulting scores are then usually transformed to a standard normal distribution to give can viagra cause a stroke scores ranging from −1 to 1, or 0 to 100 for ease of interpretation.

This enables further examination of the association between the score and a trait and the predictive ability of different scores generated by different models. Similar to other biomarker analyses, this involves using the PGS as a predictor of a trait with other covariates (eg, age, smoking, and so on) added, if appropriate, in a target sample can viagra cause a stroke. Examination of differences in the distribution of scores in cases and controls, or by examining differences in traits between different strata of PGS can enable assessment of predictive ability (figure 3). Common practice is for individual-level PGS values to be used to stratify populations into distinct groups of risk based on percentile cut-off or can viagra cause a stroke threshold values (eg, the top 1%).Example distribution of polygenic scores across a population.

Thresholds can be set to stratify risk as low (some), average (most) and high (some)." data-icon-position data-hide-link-title="0">Figure 3 Example distribution of polygenic scores across a population. Thresholds can be set to stratify risk as low (some), average (most) and high (some).Model validationPolygenic model development is reliant on can viagra cause a stroke further data sets for model testing and validation and the composition of these data sets is important in ensuring that the models are appropriate for a particular purpose. The development of a model to calculate a PGS involves refinement of the previously discussed input parameters, and can viagra cause a stroke selection of the ‘best’ of several models based on performance (figure 2). Therefore, a testing/training data set is often required to assess the model’s ability to accurately predict the trait of interest.

This is often can viagra cause a stroke a data set that is independent of the base/input/discovery data set. It may comprise a subset of the discovery data set that is only used for testing and was not included in the initial development of the model but should ideally be a separate independent data set.Genotype and phenotype data are needed in these data sets. Polygenic models are used to calculate PGS for individuals in the training data set and regression analysis can viagra cause a stroke is performed with the PGS as a predictor of a trait. Other covariates may also be included, if appropriate.

This testing can viagra cause a stroke phase can be considered a process for identifying models with better overall performance and/or informing refinements needed. Hence, this phase often involves comparison of different models that are developed using the same input data set to identify those models that have optimal performance.The primary purpose is to determine which model best discriminates between cases and controls. The area under the curve (AUC) or the C-statistic is the most can viagra cause a stroke commonly used measure in assessing discriminative ability. It has been criticised as being an insensitive measure that is not able to fully capture all aspects of predictive ability.

For instance, in some instances, can viagra cause a stroke AUC can remain unchanged between models but the individuals within are categorised into a different risk group.43 Alternative metrics that have been used to evaluate model performance include increase in risk difference, integrated discrimination improvement, R2 (estimate of variance explained by the PGS after covariate adjustment), net classification index and the relative risk (highest percentile vs lowest percentile). A clear understanding on how to interpret the performance within various settings is important in determining which model is most suitable.44As per normal practice when developing any prediction model, polygenic models with the optimal performance in a testing/training data set should be further validated in external data sets. External data sets are critical in validation of models and assessment of can viagra cause a stroke generalisability, hence must also conform to the desired situations in which a model is to be used. The goal is to find a model with suitable parameters of predictive performance in data sets outside of those in which it was developed.

Ideally, external validation requires replication in independent data sets can viagra cause a stroke. Few existing polygenic models have been validated to this extent, the focus being rather on the development of new models rather than evaluation of existing ones. One example where replication has been carried out is in the field of CAD, where the GPSCAD45 and metaGRSCAD10 polygenic models (both developed using UK Biobank data) were evaluated in a Finnish population cohort.46 Predictive ability was found to be can viagra cause a stroke lower in the Finnish population. This is likely to be due to the differences in genetic structure of this population can viagra cause a stroke and the population of the data set used for polygenic model development.

Research is ongoing to evaluate polygenic models in other populations and strategies are being developed to ensure the same performance when used more widely, possibly through reweighting and adjustment of the scores.47Moving towards clinical applicationsPGS are thought to be useful information that could improve risk estimation and provide an avenue for disease prevention and deciding treatment strategies. There are indications from a number of fields that genetic information in the form of can viagra cause a stroke PGS can act as independent biomarkers and aid stratification.11 16 48 However, the clinical benefits of stratification using a PGS and the implications for clinical practice are only just beginning to be examined. The use of PGS as part of existing risk prediction tools or as a stand-alone predictor has been suggested. This latter option may be true for diseases where knowledge or predictive ability with other risk factors is limited, such as in prostate cancer.49 In either case, polygenic models need to be individually examined to determine suitability and applicability for the specific clinical question.50 Despite some commercial companies developing PGS,51 52 can viagra cause a stroke currently PGS are not an established part of clinical practice.Integration into clinical practice requires evaluation of a PGS-based test.

An important concept to consider in this regard is the distinction between an assay and a test. This has been previously discussed with respect to genetic test can viagra cause a stroke evaluation.53 54 It is worth examining this concept as applied to PGS, as their evaluation is reliant on a clear understanding of the test to be offered. As outlined by Zimmern and Kroese,54 the method used to analyse a substance in a sample is considered the assay, whereas a test is the use of an assay within a specific context. With respect to PGS, the process of developing a model to derive a score can be considered the assay, while the use of this model for a particular disease, population and purpose can be considered the test can viagra cause a stroke.

This distinction is important when assessing if studies are reporting on assay performance as opposed to test performance. It is our view that, with respect to can viagra cause a stroke polygenic models, progress has been made with respect to assay development, but PGS-based tests are yet to be developed and evaluated. This can enable a clearer understanding of their potential clinical utility and issues that may arise for clinical implementation.11 18 55 It is clear that this is still an evolving field, and going forward different models may be required for different traits due to their underlying genetic architecture,26 different clinical contexts and needs.Clinical contexts where risk stratification is already established practice are most likely where implementation of PGS will occur first. Risk prediction models based on non-genetic factors have been developed for many conditions and are used in clinical care, for example, in cardiovascular disease over 100 such can viagra cause a stroke models exist.56 In such contexts, how a PGS and its ability to predict risk compared with, or improves on, these existing models is being investigated.3 44 57–61 The extent to which PGS improves prediction, as well as the cost implications of including this, is likely to impact on implementation.Integration of PGS into clinical practice, for any application, requires robust and validated mechanisms to generate these scores.

Therefore, given the numerous models available, an assessment of their suitability as part of a test is required. Parameters or guidelines with respect to aspects can viagra cause a stroke of model performance and metrics that could assist in selecting the model to take forward as a PGS-based test are limited and need to be addressed. Currently, there are different mechanisms to generate PGS and have arisen in response to the challenges in aggregating large-scale genomic data for prediction. For example, a review reported 29 PGS models for breast cancer from 22 publications.62 Due to there being a number of different methodologies to generate a score, numerous models may exist for the same condition and each of the can viagra cause a stroke resulting models could perform differently.

Models may perform differently because the population, measured outcome or context of the development data sets used to generate the models is diverse, for example, a score for risk of breast cancer versus a breast cancer subtype.44 63 This diversity, alongside the lack of established best practice and standardised reporting in publications, makes comparison can viagra cause a stroke and evaluation of polygenic models for use in clinical settings challenging. It is clear that moving the field forward is reliant on transparent reporting and evaluation. Recommendations for best practices on the reporting of polygenic models in literature have been proposed14 64 as well as a database,65 66 which could allow for can viagra cause a stroke such comparisons. Statements and guidelines for risk prediction model development, such as the Genetic Risk Prediction Studies and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD), already exist, but are not consistently used.

TRIPOD explicitly covers the development and validation of prediction models for both diagnosis and prognosis, for all medical domains.One clear issue is generalisability and drop in performance of polygenic models once they are applied in a population group different from the one in which they were developed.22 46 67–70 This is an ongoing challenge in genomics as most GWAS, from which most PGS are being developed, have been conducted in European-Caucasian populations.71 Efforts to improve representation are underway72 and there are attempts to reweight/adjust scores when applied to different population can viagra cause a stroke groups which are showing some potential but need further research.47 Others have demonstrated that models developed in more diverse population groups have improved performance when applied to external data sets in different populations.24 73 It is important to consider this issue when moving towards clinical applications as it may pose an ethical challenge if the PGS is not generalisable.A greater understanding of different complex traits and the impact of pleiotropy is only beginning to be investigated.74 There is growing appreciation of the role of pleiotropy as multiple variants have been identified to be associated with multiple traits and exert diverse effects, providing insight into overlapping mechanisms.75 76 This, together with the impact of population stratification, genetic relatedness, ascertainment and other sources of heterogeneity leading to spurious signals and reduced power in genetic association studies, all impacting on the predictive ability of PGS in different populations and for different diseases.While many publications report on model development and evaluation, often there is a lack of clarity on intended purpose,50 77 leading to uncertainties as to the clinical pathways in which implementation is envisaged. A clear description of intended use within clinical pathways is a central component in evaluating the use of an application with any form of PGS and in considering practical implications, such as mechanisms of obtaining the score, incorporation into health records, interpretation of scores, relevant cut-offs for intervention initiation, mechanisms for feedback of results and costs, among other issues. These parameters will also be impacted by the polygenic model that is taken forward for implementation can viagra cause a stroke. Meaning that there are still some important questions that need to be addressed to determine how and where PGS could work within current healthcare systems, particularly at a population level.78It is widely accepted that genotyping using arrays is a lower cost endeavour in comparison to genome sequencing, making the incorporation of PGS into routine healthcare an attractive proposition.

However, we were unable to find any studies reporting on can viagra cause a stroke the use or associated costs of such technology for population screening. Studies are beginning to examine use case scenarios and model cost-effectiveness, but this has only been in very few, specific investigations.79 80 Costs will also be influenced by the testing technology and by the downstream consequences of testing, which is likely to differ depending on specific applications that are developed and the pathways in which such tests are incorporated. This is particularly the case in screening or primary care settings, where such testing is can viagra cause a stroke currently not an established part of care pathways and may require additional resources, not least as a result of the volume of testing that could be expected. Moving forward, the clinical role of PGS needs to be developed further, including defining the clinical applications as well as supporting evidence, for example, on the effect of clinical outcomes, the feasibility for use in routine practice and cost-effectiveness.ConclusionThere is a large amount of diversity in the PGS field with respect to model development approaches, and this continues to evolve.

There is rapid progress which is being driven by the availability of larger data sets, primarily from GWAS and concomitant developments in statistical can viagra cause a stroke methodologies. As understanding and knowledge develops, the usefulness and appropriateness of polygenic models for different diseases and contexts are being explored. Nevertheless, this can viagra cause a stroke is still an emerging field, with a variable evidence base demonstrating some potential. The validity of PGS needs to be clearly demonstrated, and their applications evaluated prior to clinical implementation..

IntroductionThere has been considerable interest in elucidating the how to buy cheap viagra online contribution of genetic factors to http://markolewis.com/ventolin-street-price the development of common diseases and using this information for better prediction of disease risk. The common disease common variant hypothesis predicts that variants that are common in the population play a role in disease susceptibility.1 Genome-wide association studies (GWAS) using single nucleotide polymorphism (SNP) arrays were developed as a mechanism by which to investigate these genetic factors and it was hoped this would lead to identification of variants associated with disease risk and subsequent development how to buy cheap viagra online of predictive tests. Variants identified as associated with particular traits by these studies, for the large part, are SNPs that individually have a minor effect on disease risk and hence, by themselves, cannot be reliably used in disease prediction. Looking at the aggregate impact of these SNPs in the form of a polygenic score (PGS) appeared to be one possible means of using this information to predict disease.2 It is thought this will be of benefit as our genetic make-up is largely stable from birth and dictates a ‘baseline risk’ on how to buy cheap viagra online which external influences act and modulate.

Therefore, PGS are a potential mechanism to act as a risk predictor by capturing information on this genetic liability.The use of PGS as a predictive biomarker is being explored in a number of different disease areas, including cancer,3 4 psychiatric disorders,5–7 metabolic disorders (diabetes,8 obesity9) and coronary artery disease (CAD).10 The proposed applications range from aiding disease diagnosis, informing selection of therapeutic interventions, improvement of risk prediction, informing disease screening and, on a personal level, informing life planning. Therefore, genetic risk information in the form of a PGS is considered to have potential in informing both clinical and individual-level decision-making.Recent advances in statistical techniques, improved computational power and the availability of large how to buy cheap viagra online data sets have led to rapid developments in this area over the past few years. This has resulted in a variety of approaches to construction of models for score calculation and the investigation of these scores for prediction of common diseases.11 Several review articles aimed at researchers with a working knowledge of this field have been produced.6 11–17 In this article, we provide an overview of the key aspects of PGS construction to assist clinicians and researchers in other areas of academia to gain an understanding of the processes involved in score construction. We also how to buy cheap viagra online consider the implications of evolving methodologies for the development of applications of PGS in healthcare.Evolution in polygenic model construction methodologiesTerminology with respect to PGS has evolved over time, reflecting evolving approaches and methodology.

Other terms include PGS, polygenic risk score, polygenic load, genotype score, genetic burden, polygenic hazard score, genetic risk score (GRS), metaGRS and allelic risk score. Throughout this article we use how to buy cheap viagra online the terms polygenic models to refer to the method used to calculate an output in the form of a PGS. Different polygenic models can be used to calculate a PGS and analysis of these scores can be used to examine associations with particular markers or to predict an individuals risk of diseases.12Usual practice in calculating PGS is as a weighted sum of a number of risk alleles carried by an individual, where the risk alleles and their weights are defined by SNPs and their measured effects (figure 1).11 Polygenic models have been constructed using a few, hundreds or thousands of SNPs, and more recently SNPs across the whole genome. Consequently, determining which SNPs to include and the disease-associated weighting to assign to SNPs are important aspects of model construction (figure 2).18 These aspects are influenced how to buy cheap viagra online by available genotype data and effect size estimates as well as the methodology employed in turning this information into model parameters (ie, weighted SNPs).Polygenic score calculation.

This calculation aggregates the SNPs and their weights selected for a polygenic score. Common diseases are thought to be influenced by many genetic variants with small individual effect sizes, such that meaningful risk prediction necessitates examining how to buy cheap viagra online the aggregated impact of these multiple variants including their weightings.

The model that performs best (as determined by one or more measures) is then selected for validation in the external data set.

The model how to buy cheap viagra online that performs best (as determined by one or more measures) is then selected for validation in the external data set. GWAS, genome-wide association studies.Changes in data availability over time have had an impact on the approach taken in SNP selection and weighting.

Early studies to identify variants associated how to buy cheap viagra online with common diseases took the form of candidate gene studies. The small size of candidate gene studies, the limitation of technologies available for genotyping and stringent significance thresholds meant that these studies investigated fewer variants and those that were identified with disease associations had relatively large effect sizes.19 Taken together, this meant that a relatively small number of variants were available for consideration for inclusion in a polygenic model.20 21 Furthermore, weighting parameters for these few variants were often simplistic, such as counts of the number of risk alleles carried, ignoring their individual effect sizes.16The advent of GWAS enabled assessment of SNPs across the genome, leading to the identification of a larger number of disease-associated variants and therefore more variants suitable for inclusion in a polygenic model. In addition, the increasing number of individuals in the association studies meant that the power of these studies increased, allowing for more precise estimates of effect sizes.19 Furthermore, some theorised that lowering stringent significance thresholds set for SNP–trait associations could also identify SNPs that might play a part in disease risk.11 16 This resulted in more options with respect to polygenic model parameters of SNPs to include and how to buy cheap viagra online weights to assign to them. However, the inclusion of more SNPs and direct application of GWAS effect sizes as a weighting parameter does not always equate to better predictive performance.4 16 This is because GWAS do not provide perfect information with respect to the causal SNP, the effect sizes or the number of SNPs that contribute to the trait.

Therefore, different methods have been developed to address these how to buy cheap viagra online issues and optimise predictive performance of the score. Current common practice is to construct models with different iterations of SNPs and weighting, with assessment of the performance of each to identify the optimum configuration of SNPs and their weights (figure 2).Methods used in SNP selection and weighting assignmentSome methods of model development will initially involve selection of SNPs followed by optimisation of weighting, whereas others may involve optimisation of weightings for all SNPs that have been genotyped using their overall GWAS effect sizes, the linkage disequilibrium (LD) and an estimate of the proportion of SNPs that are expected to contribute to the risk.22LD is the phenomenon where some SNPs are coinherited more frequently with other SNPs due to their close proximity on the genome. Segments with strong LD between SNPs are referred to as haplotype how to buy cheap viagra online blocks. This phenomenon means that GWAS often identify multiple SNPs in the same haplotype block associated with disease and the true causal SNP is not known.

As models have started to assess more SNPs, careful consideration is required to take into account possible correlation between SNPs as a result how to buy cheap viagra online of this phenomenon. Correlation between SNPs can lead to double counting of SNPs and association redundancy, where multiple SNPs how to buy cheap viagra online in a region of LD are identified as being associated with the outcome. This can lead to reduction in the predictive performance of the model. Therefore, processes for filtering SNPs and using one SNP (tag how to buy cheap viagra online SNP) to act as a marker in an area of high LD, through LD thinning, were developed.

Through these processes SNPs correlated with other SNPs in a block are removed, by either pruning or clumping. Pruning ignores p how to buy cheap viagra online value thresholds and ‘eliminates’ SNPs by a process of iterative comparison between a pair of SNPs to assess if they are correlated, and subsequently could remove SNPs that are deemed to have evidence of association. Clumping (also known as informed pruning) is guided by GWAS p values and chooses the most significant SNP, therefore keeping the most significant SNP within a block.23 This is all done with the aim of pinpointing relatively small areas of the genome that contribute to risk of the trait. Different significance thresholds may be used to select SNPs from this subgroup for inclusion in models.Poor performance of a model can result from imperfect tagging with the underlying causal SNP.16 This is because the causal SNP that is associated with disease might not be in LD with the tag SNP that is in the model but is in how to buy cheap viagra online LD with another SNP which is not in the model.

This particularly occurs where the LD and variant frequency differs between population groups.24 An alternate approach to filter SNPs is stepwise regression where SNPs are selected based on how much the SNPs improve the model’s performance. This is a statistical approach and does not consider the impact of LD or effect size.As described above, early studies used simple weighting approaches or directly how to buy cheap viagra online applied effect sizes from GWAS as weighting parameters for SNPs. However, application of effect sizes as a weighting parameter directly from a GWAS may not be optimal, due to differences in the population that the GWAS was conducted in and the target population. Also as described above, LD and the fact that not all SNPs may contribute to how to buy cheap viagra online the trait mean that these effect sizes from GWAS are imperfect estimates.

Therefore, methods have been developed that adjust effect size estimates from GWAS using statistical techniques which make assumptions about factors such as the number of causal SNPs, level of LD between SNPs or knowledge of their potential function to better reflect their impact on a trait. Numerous statistical methodologies have been developed to improve weighting with a view to enhancing the discriminative power of a PGS.25 26 Examples of some methodological how to buy cheap viagra online approaches are LDpred,22 winner’s curse correction,23 empirical Bayes estimation,27 shrinkage regression (Lasso),28 linear mixed models,29 with more being developed or tested. An additional improvement on the methods is to embed non-genetic information (eg, age-specific ORs).6 Determination of which methodology or hybrid of methodologies is most appropriate for various settings and conditions is continuously being explored and is evolving with new statistical approaches developing at a rapid pace.In summary, model development has evolved in an attempt to gain the most from available GWAS data and address some of the issues that arise due to working with data sets which cannot be directly translated into parameters for prediction models. The different approaches taken in SNP selection and weighting, and how to buy cheap viagra online the impact on the predictive performance of a model are important to consider when assessing different models.

This is because different approaches to PGS modelling can achieve the same or a similar level of prediction. From a health system implementation perspective, particular approaches may be preferred following practical considerations and trade-offs between obtaining genotype data, processes for score construction how to buy cheap viagra online and model performance. In addition, the degree to which these parameters need to be optimised will also be impacted by the input data and validation data set, and the quality control procedures how to buy cheap viagra online that need to be applied to these data sets.12Sources of input data for score constructionKey to the development of a polygenic model is the availability of data sets that can provide input parameters for model construction. Genotype data used in model construction can either be available as raw GWAS data or provided as GWAS summary statistics.

Data in the raw format are individual-level data from a SNP array and may not have undergone basic quality control such as assessment of missingness, sex discrepancy checks, deviation from Hardy-Weinberg equilibrium, heterozygosity rate, relatedness or assessment for outliers.30 31 Availability of raw GWAS data allows for different polygenic models to be developed how to buy cheap viagra online because of the richness of the data, however computational issues arise because of the size of the data sets. Data based on genome sequencing, as opposed to SNP arrays, could also be used in model construction. There have been limited studies of PGS developed from this form of data due to limitations in data availability, which is mainly due to cost restraints.15 32 Individual-level genomic data are also often not available to researchers due to privacy concerns.Due to these issues, the focus of polygenic model development has therefore been on using well-powered GWAS summary statistics.33 These are how to buy cheap viagra online available from open access repositories and contain summary information such as the allele positions, ORs, CIs and allele frequency, without containing confidential information on individuals. These data sets have usually been through the basic quality control measures mentioned above.

There are, however, no standards for publicly available files, meaning some further processing steps may be required, how to buy cheap viagra online in particular when various data sets are combined for a meta-analysis. Quality control on summary statistics is only possible if information such as missing genotype rate, minor allele frequency, Hardy-Weinberg equilibrium failures and non-Mendelian transmission rates is provided.12Processing of GWAS data may include additional quality control steps, imputation and filtering of the SNP information, which can be done at the level of genotype or summary statistics data. SNP arrays used in GWAS only have common SNPs represented on them as how to buy cheap viagra online they rely on LD between SNPs to cover the entire genome. As described above, one tag SNP on the array can represent many other SNPs.

Imputation of SNPs is common in how to buy cheap viagra online GWAS and describes the process of predicting genotypes that have not been directly genotyped but are statistically inferred (imputed) based on haplotype blocks from a reference sequence.33–35 Often association tests between the imputed SNPs and trait are repeated. As genotype imputation requires individual-level data, researchers have proposed summary statistics imputation as a mechanism to infer the association between untyped SNPs and a trait. The performance of imputation has been evaluated and shown that, with certain limitations, summary statistics imputation is an efficient and cost-effective methodology to identify loci associated with traits when compared with imputation done on genotypes.36An alternative source of input data for the selection of SNPs and their weightings is through literature or in existing how to buy cheap viagra online databases, where already known trait-associated SNPs and their effect sizes are used as the input parameters in model development. A number of studies have taken this approach37 38 and it is possible to use multiple sources when developing various polygenic models and establishing the preferred parameters to use.Currently, there does not appear to be one methodology that works across all contexts and traits, each trait will need to be assessed to determine which method is the most suitable for the trait being evaluated.

For example, four different polygenic model construction strategies were explored for three skin cancer subtypes4 by using data on SNPs and their effect sizes from different sources, such as how to buy cheap viagra online the latest GWAS meta-analysis results, the National Human Genome Research Institute (NHGRI) EBI GWAS catalogue, UK Biobank GWAS summary statistics with different thresholds and GWAS summary statistics with LDpred. In this setting for basal cell carcinoma and melanoma, the meta-analysis and catalogue-derived models were found to perform similarly but that the latter was ultimately used as it included more SNPs. For squamous cell how to buy cheap viagra online carcinoma the meta-analysis-derived model performed better than the catalogue-derived model. This demonstrates how each disease subtype, model construction strategy and data set can have their own limitations and advantages.Knowledge of the sources of input data and its subsequent use in model development is important in how to buy cheap viagra online understanding the limitations of available models.

Models that are developed using data sets that reflect the population in which prediction is to be carried out will perform better. For example, data collected from a symptomatic or high-risk population may not be suitable as an input data set for the development of a polygenic model how to buy cheap viagra online that will be used for disease prediction in the general population. Large GWAS studies were previously focused on high-risk individuals, such as patients with breast cancer with a strong family history or known pathogenic variants in BRCA1 or BRCA2. These studies would not be suitable for the development of PGS for use in how to buy cheap viagra online the general population but can inform risk assessment in high-risk individuals.

The source of the data for SNP selection and weighting also has implications for downstream uses and validation. For example, variant frequency and LD patterns can vary between populations and this can translate to poor performance of the polygenic model if the external validation population is different from that of the input data set.39–41 Furthermore, the power and validity of polygenic analyses are influenced by the input data sources.12 42From how to buy cheap viagra online a model to a scorePGS can be calculated using one of the methodologies discussed above. The resulting PGS units of measurement depend on which measurement is used for the weighting.12 For example, the weightings may have been calculated based on logOR for discrete traits or linear regression coefficient (β/beta) in continuous traits from univariate regression tests carried out in the GWAS. The resulting scores are then usually transformed to a standard normal distribution to give scores ranging how to buy cheap viagra online from −1 to 1, or 0 to 100 for ease of interpretation.

This enables further examination of the association between the score and a trait and the predictive ability of different scores generated by different models. Similar to other biomarker analyses, this involves using the PGS as a predictor of a trait with other covariates (eg, age, smoking, and so on) added, how to buy cheap viagra online if appropriate, in a target sample. Examination of differences in the distribution of scores in cases and controls, or by examining differences in traits between different strata of PGS can enable assessment of predictive ability (figure 3). Common practice is for individual-level PGS values to be used to how to buy cheap viagra online stratify populations into distinct groups of risk based on percentile cut-off or threshold values (eg, the top 1%).Example distribution of polygenic scores across a population.

Thresholds can be set to stratify risk as low (some), average (most) and high (some)." data-icon-position data-hide-link-title="0">Figure 3 Example distribution of polygenic scores across a population. Thresholds can be set to stratify risk as low how to buy cheap viagra online (some), average (most) and high (some).Model validationPolygenic model development is reliant on further data sets for model testing and validation and the composition of these data sets is important in ensuring that the models are appropriate for a particular purpose. The development of a model to calculate a PGS involves refinement of the previously discussed input parameters, and selection of the ‘best’ of several models based on performance (figure how to buy cheap viagra online 2). Therefore, a testing/training data set is often required to assess the model’s ability to accurately predict the trait of interest.

This is often how to buy cheap viagra online a data set that is independent of the base/input/discovery data set. It may comprise a subset of the discovery data set that is only used for testing and was not included in the initial development of the model but should ideally be a separate independent data set.Genotype and phenotype data are needed in these data sets. Polygenic models are used to calculate PGS for individuals in the training data set and regression analysis is performed with the how to buy cheap viagra online PGS as a predictor of a trait. Other covariates may also be included, if appropriate.

This testing phase can be considered a process for identifying models with better overall performance and/or how to buy cheap viagra online informing refinements needed. Hence, this phase often involves comparison of different models that are developed using the same input data set to identify those models that have optimal performance.The primary purpose is to determine which model best discriminates between cases and controls. The area how to buy cheap viagra online under the curve (AUC) or the C-statistic is the most commonly used measure in assessing discriminative ability. It has been criticised as being an insensitive measure that is not able to fully capture all aspects of predictive ability.

For instance, in some instances, AUC can remain unchanged between models but the individuals within are how to buy cheap viagra online categorised into a different risk group.43 Alternative metrics that have been used to evaluate model performance include increase in risk difference, integrated discrimination improvement, R2 (estimate of variance explained by the PGS after covariate adjustment), net classification index and the relative risk (highest percentile vs lowest percentile). A clear understanding on how to interpret the performance within various settings is important in determining which model is most suitable.44As per normal practice when developing any prediction model, polygenic models with the optimal performance in a testing/training data set should be further validated in external data sets. External data sets are critical how to buy cheap viagra online in validation of models and assessment of generalisability, hence must also conform to the desired situations in which a model is to be used. The goal is to find a model with suitable parameters of predictive performance in data sets outside of those in which it was developed.

Ideally, external how to buy cheap viagra online validation requires replication in independent data sets. Few existing polygenic models have been validated to this extent, the focus being rather on the development of new models rather than evaluation of existing ones. One example where replication has how to buy cheap viagra online been carried out is in the field of CAD, where the GPSCAD45 and metaGRSCAD10 polygenic models (both developed using UK Biobank data) were evaluated in a Finnish population cohort.46 Predictive ability was found to be lower in the Finnish population. This is likely to be due to the differences in genetic structure of this population and the population of the data set used for how to buy cheap viagra online polygenic model development.

Research is ongoing to evaluate polygenic models in other populations and strategies are being developed to ensure the same performance when used more widely, possibly through reweighting and adjustment of the scores.47Moving towards clinical applicationsPGS are thought to be useful information that could improve risk estimation and provide an avenue for disease prevention and deciding treatment strategies. There are indications from a number of fields that genetic information in the form of PGS can act as independent biomarkers and aid stratification.11 16 48 However, the clinical benefits of how to buy cheap viagra online stratification using a PGS and the implications for clinical practice are only just beginning to be examined. The use of PGS as part of existing risk prediction tools or as a stand-alone predictor has been suggested. This latter option may be true for diseases where knowledge or predictive ability with other risk factors is limited, such as in prostate cancer.49 In either case, polygenic models need to be individually examined to determine suitability and applicability for the specific clinical question.50 Despite how to buy cheap viagra online some commercial companies developing PGS,51 52 currently PGS are not an established part of clinical practice.Integration into clinical practice requires evaluation of a PGS-based test.

An important concept to consider in this regard is the distinction between an assay and a test. This has been previously discussed with respect to how to buy cheap viagra online genetic test evaluation.53 54 It is worth examining this concept as applied to PGS, as their evaluation is reliant on a clear understanding of the test to be offered. As outlined by Zimmern and Kroese,54 the method used to analyse a substance in a sample is considered the assay, whereas a test is the use of an assay within a specific context. With respect to PGS, the process of developing a model to derive a score can be considered the assay, while how to buy cheap viagra online the use of this model for a particular disease, population and purpose can be considered the test.

This distinction is important when assessing if studies are reporting on assay performance as opposed to test performance. It is our how to buy cheap viagra online view that, with respect to polygenic models, progress has been made with respect to assay development, but PGS-based tests are yet to be developed and evaluated. This can enable a clearer understanding of their potential clinical utility and issues that may arise for clinical implementation.11 18 55 It is clear that this is still an evolving field, and going forward different models may be required for different traits due to their underlying genetic architecture,26 different clinical contexts and needs.Clinical contexts where risk stratification is already established practice are most likely where implementation of PGS will occur first. Risk prediction models based on non-genetic factors have been developed for many conditions and are used in clinical care, for example, in cardiovascular disease over 100 such models exist.56 In such contexts, how a PGS and its ability to predict risk compared with, or improves on, these existing models is being investigated.3 44 57–61 The extent to which PGS improves prediction, as well as the cost implications of including this, is likely to impact on implementation.Integration of PGS into clinical practice, for any application, requires robust and validated how to buy cheap viagra online mechanisms to generate these scores.

Therefore, given the numerous models available, an assessment of their suitability as part of a test is required. Parameters or guidelines with respect to aspects of how to buy cheap viagra online model performance and metrics that could assist in selecting the model to take forward as a PGS-based test are limited and need to be addressed. Currently, there are different mechanisms to generate PGS and have arisen in response to the challenges in aggregating large-scale genomic data for prediction. For example, a review reported 29 PGS models for breast cancer from 22 publications.62 Due to there being a number of different methodologies to generate a score, numerous models may how to buy cheap viagra online exist for the same condition and each of the resulting models could perform differently.

Models may perform differently because the population, measured outcome or context of the development data sets used to generate the models is diverse, for example, a score for risk of breast how to buy cheap viagra online cancer versus a breast cancer subtype.44 63 This diversity, alongside the lack of established best practice and standardised reporting in publications, makes comparison and evaluation of polygenic models for use in clinical settings challenging. It is clear that moving the field forward is reliant on transparent reporting and evaluation. Recommendations for best practices on the reporting of polygenic models how to buy cheap viagra online in literature have been proposed14 64 as well as a database,65 66 which could allow for such comparisons. Statements and guidelines for risk prediction model development, such as the Genetic Risk Prediction Studies and Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD), already exist, but are not consistently used.

TRIPOD explicitly covers the development and validation of prediction models for both diagnosis and prognosis, for all medical domains.One clear issue is generalisability and drop in performance of polygenic models once they are applied in a population group different from the one in which they were developed.22 46 67–70 This is an ongoing challenge in genomics as most GWAS, from which most PGS are being developed, have been conducted in European-Caucasian populations.71 Efforts to improve representation are underway72 and there are attempts to reweight/adjust scores when applied to different population groups which are showing some potential but need further research.47 Others have demonstrated that models developed in more diverse population groups have improved how to buy cheap viagra online performance when applied to external data sets in different populations.24 73 It is important to consider this issue when moving towards clinical applications as it may pose an ethical challenge if the PGS is not generalisable.A greater understanding of different complex traits and the impact of pleiotropy is only beginning to be investigated.74 There is growing appreciation of the role of pleiotropy as multiple variants have been identified to be associated with multiple traits and exert diverse effects, providing insight into overlapping mechanisms.75 76 This, together with the impact of population stratification, genetic relatedness, ascertainment and other sources of heterogeneity leading to spurious signals and reduced power in genetic association studies, all impacting on the predictive ability of PGS in different populations and for different diseases.While many publications report on model development and evaluation, often there is a lack of clarity on intended purpose,50 77 leading to uncertainties as to the clinical pathways in which implementation is envisaged. A clear description of intended use within clinical pathways is a central component in evaluating the use of an application with any form of PGS and in considering practical implications, such as mechanisms of obtaining the score, incorporation into health records, interpretation of scores, relevant cut-offs for intervention initiation, mechanisms for feedback of results and costs, among other issues. These parameters will also be impacted by the polygenic model that is taken forward for implementation how to buy cheap viagra online. Meaning that there are still some important questions that need to be addressed to determine how and where PGS could work within current healthcare systems, particularly at a population level.78It is widely accepted that genotyping using arrays is a lower cost endeavour in comparison to genome sequencing, making the incorporation of PGS into routine healthcare an attractive proposition.

However, we were unable to find any studies reporting on the use how to buy cheap viagra online or associated costs of such technology for population screening. Studies are beginning to examine use case scenarios and model cost-effectiveness, but this has only been in very few, specific investigations.79 80 Costs will also be influenced by the testing technology and by the downstream consequences of testing, which is likely to differ depending on specific applications that are developed and the pathways in which such tests are incorporated. This is particularly the case in screening or primary care settings, how to buy cheap viagra online where such testing is currently not an established part of care pathways and may require additional resources, not least as a result of the volume of testing that could be expected. Moving forward, the clinical role of PGS needs to be developed further, including defining the clinical applications as well as supporting evidence, for example, on the effect of clinical outcomes, the feasibility for use in routine practice and cost-effectiveness.ConclusionThere is a large amount of diversity in the PGS field with respect to model development approaches, and this continues to evolve.

There is rapid progress which is being driven by the availability of larger data sets, primarily how to buy cheap viagra online from GWAS and concomitant developments in statistical methodologies. As understanding and knowledge develops, the usefulness and appropriateness of polygenic models for different diseases and contexts are being explored. Nevertheless, this how to buy cheap viagra online is still an emerging field, with a variable evidence base demonstrating some potential. The validity of PGS needs to be clearly demonstrated, and their applications evaluated prior to clinical implementation..

How to get viagra over the counter

With its choice of a new leader, the Florida Hospital Association has signaled that seeking how to get viagra over the counter legislative approval to expand Medicaid to http://mpressiv.com/best-price-on-levitra-canada/ nearly 850,000 uninsured adults won't be among its top priorities.In October, Mary Mayhew became the association's CEO. Mayhew, who led the state's Medicaid agency since 2019, has been a vocal critic of the Affordable Care Act's Medicaid expansion adopted by how to get viagra over the counter 38 other states. She has argued that expansion puts states in a difficult position because the federal government is unlikely to keep its financial commitment to pay its share of the costs.

Had Medicaid been expanded in Florida, hospitals there would have gained how to get viagra over the counter thousands of paying patients. But the institutions have how to get viagra over the counter done little in recent years to persuade the Republican-led legislature and Gov. Ron DeSantis, also Republican, who oppose such a move.Mayhew acknowledged in an interview with KHN that expanding Medicaid to cover more uninsured patients could help hospitals financially, especially at a time when facilities have seen demand for services decline as people avoid care for fear of contracting erectile dysfunction treatment.With that in mind, she said, she is now open to the idea of expanding Medicaid.

"We need to how to get viagra over the counter look at all options on the table," she said. "Is it how to get viagra over the counter doable?. Yes."Still, she was quick to point out concerns about whether Florida can afford to expand.Under the ACA, the federal government pays 90% of the costs for newly enrolled Medicaid recipients.

In the traditional Medicaid program — which covers children, people who are disabled and pregnant women — the federal government pays nearly two-thirds of Florida's Medicaid costs."It will be financially how to get viagra over the counter challenging in our state budget as revenues have dropped," Mayhew said, echoing comments of state officials. "That 10% how to get viagra over the counter cost has to come from somewhere."Mayhew's hire worries advocates who have spent more than seven years lobbying lawmakers to expand Medicaid. Without strong support from the hospital industry, they fear they're unlikely to change many votes."It may make it harder," said Karen Woodall, executive director of Florida People's Advocacy Center, a group that lobbies for policies to help low-income citizens.

Marshaling hospital support is important, she said, because of the industry's money and political clout.In many state capitals, hospitals have led the fight how to get viagra over the counter for Medicaid expansion either by lobbying lawmakers or bankrolling ballot initiatives. The latest example was in Missouri, which this summer expanded Medicaid via how to get viagra over the counter a voter initiative. The campaign for the measure was partly funded by hospitals.But in Florida, hospitals appear to have made a calculated decision to avoid pushing an initiative that Republican leaders have said they don't want.

Among the dozen states that have not expanded Medicaid, how to get viagra over the counter Florida is second only to Texas in the number of residents who could gain coverage.Aurelio Fernandez, CEO of Memorial Healthcare System in Hollywood, Florida, who was chair of the hospital association board when it hired Mayhew, said her opposition to Medicaid expansion never came up in the process. The association hired Mayhew due to the "phenomenal job" she did guiding hospitals amid the erectile dysfunction treatment viagra, he said."There is no appetite at this juncture [for the legislature] to expand the Medicaid program with Obamacare," said Fernandez, despite his belief that expansion would help hospitals and patients.Mayhew, sounding more like a state official than a hospital industry spokesperson, said the ultimate decision on expansion will be up to lawmakers, how to get viagra over the counter who must review spending priorities. When states face a financial crunch, lawmakers look to reduce spending in education and Medicaid, which are the biggest parts of the budget, she said."The last thing we want to see is the state budget balanced on the backs of hospitals with deep Medicaid reimbursement cuts," Mayhew said.Mayhew said her previous opposition to expanding Medicaid occurred when she was responsible for balancing the state budget and managing the programs in Florida and, before that, in Maine.

When she ran Maine's program, she said she opposed expanding Medicaid to allow nondisabled adults into the program while there were disabled enrollees already on waiting lists to get care.The Florida Hospital Association, which represents more than 200 hospitals, spent years lobbying state lawmakers to how to get viagra over the counter expand Medicaid. But since DeSantis was elected in 2018, the group has focused on other issues because the governor and Republican lawmakers made clear they would not expand the program.Asked what the association's current position is on Medicaid expansion, Mayhew noted she has been in her job less than a month and "we have not had that policy decision by the board for me to answer that."Miriam Harmatz, executive director of the Florida Health Justice Project, an advocacy group, said Mayhew's hire suggests that hospitals are unlikely to get behind a fledgling effort to put the expansion question to voters in 2022.Others advocating for Medicaid expansion agree."It does not look like they [Florida's hospitals] are on board with helping us expand Medicaid at the moment," said Louisa how to get viagra over the counter McQueeney, program director of Florida Voices for Health, a consumer group helping with the ballot initiative.KHN (Kaiser Health News) is a nonprofit news service covering health issues.
