Report Details HIV/AIDS Efforts in NYC From 2009 to 2011


Deaths from HIV/AIDS in New York City have declined faster than other causes of death in the city, according to Living Healthy 2009–2011, a report by the NYC Department of Health and Mental Hygiene. They’re down 17.9 percent since 2009 and nearly 55 percent since 2002.

In 2011, the city distributed for free more than 36 million male condoms and more than 1 million female condoms. This free condom distribution is the largest such public program nationwide.

Anti-HIV drug effort in South Africa yields dramatic results

Two studies find that an expensive antiretroviral drug campaign in rural KwaZulu-Natal province has reduced risk and extended life expectancy by more than 11 years.

An intensive campaign to combat HIV/AIDS with costly antiretroviral drugs in rural South Africa has increased life expectancy by more than 11 years and significantly reduced the risk of infection for healthy individuals, according to new research.

The two studies, published Thursday in the journal Science, come as wealthy Western nations are debating how best to stretch limited AIDS funding at a time of economic stress.

With an annual price tag of $500 to $900 per patient, antiretroviral therapy programs have stirred frequent debate. Critics argue that adherence to the drug regimen is low and social stigma prevents some from seeking care until they are very ill and have infected others. Cheaper remedies, such as condom distribution, male circumcision and behavior modification, deserve more attention and funding, they say.

The new economic analysis of a $10.8-million campaign in KwaZulu-Natal province concluded that the drug scale-up there had been highly cost-effective.

The program was administered by nurses in rural health clinics in an impoverished region of about 100,000 people. Treatment consisted primarily of daily doses of antiretroviral therapy, or ART, drugs, which patients take every day for their entire lives. Patients picked up their medication at a rural clinic once a month.

In 2003, the year before the drugs were available, 29% of all residents were infected with HIV and half of all deaths there were caused by AIDS. Life expectancy in the region was just over 49 years.

By 2011, life expectancy had grown to 60 1/2 years — “the most rapid life expectancy gains observed in the history of public health,” said study senior author Till Barnighausen, a global health professor at the Harvard School of Public Health.

Based on that increase in longevity, researchers determined just how many years of life were effectively “gained” among residents as a result of ART intervention. They used that figure and the total expense of the program to calculate a cost-effectiveness ratio of $1,593 per life-year saved.

The World Health Organization considers medical intervention to be “highly cost-effective” if the cost per year of life saved is less than a nation’s per capita gross domestic product. The program’s ratio was well below South Africa’s 2011 per capita GDP of about $11,000.

“It’s really a slam dunk of an intervention,” said study leader Jacob Bor, a graduate student at Harvard. “These investments are worthwhile.”

The research team noted that the study period coincided with the arrival of electric power and clean water for area residents. But those alone could not explain the dramatic increase in longevity, they said.

“While mortality due to HIV declined precipitously, mortality due to other causes flat-lined,” Bor said. “These changes were almost certainly due to ART scale-up.”

In a second study from the same region, researchers followed nearly 17,000 healthy people from 2004 to 2011 to determine HIV infection rates in areas with active ART intervention programs.

Healthy individuals in those areas were 38% less likely to contract HIV than people in areas where ART drugs were not widely available, researchers found. People in extremely rural areas also fared better than those in more closely populated areas clustered around national roads.

Overall HIV prevalence increased 6% during the seven years of the study, probably because the antiretroviral drugs allowed people with the virus to live longer, according to the report.

It’s not clear how the results of the new study would translate to areas where stable, cohabiting couples were not the norm, said lead author Frank Tanser, an epidemiologist at the University of KwaZulu-Natal.

AIDS researchers who weren’t involved in the studies said they provide strong support for maintaining programs like the President’s Emergency Plan for AIDS Relief, begun by PresidentGeorge W. Bush in 2003.

“These papers present truly remarkable data,” said Dr. Douglas Richman, director of the Center for AIDS Research at UC San Diego.

Sex Diseases Cost $16 Billion a Year to Treat, CDC Says

Bloomberg     (02.14.13):: Elizabeth Lopatto

CDC reported that it costs the United States $16 billion annually to treat eight STDs—HIV, syphilis, gonorrhea, hepatitis B, chlamydia, trichomoniasis, herpes, and human papillomavirus (HPV). CDC’s most recent comprehensive data (2008) estimates there are 19.7 million newly diagnosed sexually transmitted infections each year, and that half of these infections occur among young people ages 15 to 24. The most common diagnosis is HPV, which has been linked to throat, cervical, and penile cancers. The report estimates 110 million total sexually transmitted infections among US men and women of all ages.

CDC Epidemiologist Catherine Satterwhite, an author of one of the reports, stated that young people—especially young women—have always been disproportionately affected by STDs because many lack good insurance or easy healthcare access. Satterwhite noted that all STDs are preventable, most are curable, and all have existing treatments. Techniques for preventing STDs include abstinence, condom use, and mutual monogamy for couples. CDC recommends boys and girls have vaccination with Merck’s Gardasil to prevent HPV. In spite of increased incidence of HPV-related cancers, use of HPV vaccine remains low.

HIV is the most expensive STD because it requires life-long treatment. Curable STDs cost $742 million annually. The most common curable STD is chlamydia. To lower prevalence, Satterwhite recommended increased testing, especially for young women, and urged all sexually active people to be tested at least once for HIV.

The full report, “Sexually Transmitted Infections Among US Women and Men: Prevalence and Incidence Estimates, 2008,” was published in the journal Sexually Transmitted Diseases (2013; doi: 10.1097/OLQ.0b013e318286bb53).

The full report, “The Estimated Direct Medical Cost of Selected Sexually Transmitted Infections in the United States, 2008,” was published in the journal Sexually Transmitted Diseases (2013; doi: 10.1097/OLQ.0b013e318285c6d2).

Guidelines for the Use of Antiretroviral Agents in HIV-1-Infected Adults and Adolescents

What’s New in the Guidelines?

(Last updated:2/12/2013; last reviewed:2/12/2013)

Printer-Friendly Files

The following key changes were made to update the March 28, 2012, version of the guidelines.

Drug-Resistance Testing
In persons failing INSTI-based regimens, the panel now recommends that a genotypic assay for INSTI resistance should be performed to determine whether to include a drug from this class in subsequent regimens (AII). Previously, the Panel recommended that INSTI resistance testing should be considered (BIII) in this setting.

Co-Receptor Tropism Assay
A genotypic tropism assay is now commercially available. The assay predicts HIV-1 co-receptor usage based on sequencing of the V3-coding region of HIV-1 env, the principal determinant of co-receptor usage. The Panel recommends that a genotypic tropism assay be used as an alternative to a phenotypic tropism assay before initiation of a CCR5 antagonist-containing regimen (BII).

Initiating ART in Treatment-Naive Patients
The Panel has updated its recommendations on initiation of ART in treatment-naive patients. The Panel’s recommendations are listed below.

  • Antiretroviral therapy (ART) is recommended for all HIV-infected individuals to reduce the risk of disease progression.
    • The strength and evidence for this recommendation vary by pretreatment CD4 cell count: CD4 count <350 cells/mm3 (AI); CD4 count 350 cells/mm3 to 500 cells/mm3 (AII); CD4 count >500 cells/mm3 (BIII).
  • ART also is recommended for HIV-infected individuals for the prevention of transmission of HIV.
    • The strength and evidence for this recommendation vary by transmission risks: perinatal transmission (AI); heterosexual transmission (AI); other transmission risk groups (AIII).
  • Patients starting ART should be willing and able to commit to treatment and understand the benefits and risks of therapy and the importance of adherence (AIII). Patients may choose to postpone therapy, and providers, on a case-by-case basis, may elect to defer therapy on the basis of clinical and/or psychosocial factors.

What to Start: Initial Combination Regimen for Antiretroviral-Naive Patients
The following changes and updates were made to this section:

  • A rilpivirine (RPV)-based regimen is now recommended as an alternative NNRTI-based regimen only in patients with pre-treatment HIV RNA ≤100,000 copies/mL (BI). This is based on results from clinical trials that show that that the proportion of patients who experienced virologic failure at 96 weeks was greater in patients with pre-treatment HIV RNA >100,000 copies/mL than in patients with pre-therapy HIV RNA ≤100,000 copies/mL.
  • Elvitegravir/cobicistat/tenofovir/emtricitabine (EVG/COBI/TDF/FTC) as a fixed-dose combination product is recommended as an alternative regimen for ART-naive patients with pre-treatment creatinine clearance >70 mL/min (BI).
  • The discussion on 3-NRTI regimens was removed from this section because 3-NRTI regimens are no longer recommended regimens for ART-naive patients.
  • Tables 5a, 5b, 6, and 7 were updated to reflect the above changes.

Acute and Recent (Early) HIV Infection

  • The term “early” HIV infection is now used when describing both the acute phase of HIV infection (i.e., immediately after HIV infection and before seroconversion) and recent (i.e., within first 6 months) HIV infection.
  • The recommendation for initiation of ART in patients with early infection was changed from “should be considered optional (CIII)” to “should be offered (BII).”
  • The section was updated to include a summary of recent randomized controlled trials that examined the role of time-limited ART in patients with early HIV infection.

HIV-Infected Women

  • The recommendation on use of efavirenz (EFV) during pregnancy was updated to be in accord with the recommendation in the Perinatal Antiretroviral Guidelines. The key update includes the following statement: “Because the risk of neural tube defects is restricted to the first 5 to 6 weeks of pregnancy and pregnancy is rarely recognized before 4 to 6 weeks of pregnancy, EFV can be continued in pregnant women receiving an EFV-based regimen who present for antenatal care in the first trimester, provided the regimen produces virologic suppression (CIII).”
  • The Panel also recommends that intravenous zidovudine use during labor may be omitted in women who have HIV RNA < 400 copies/mL near delivery (BII). Oral combination ART should be continued during labor.

Drug-Drug Interaction

  • This section includes new information under the heading “Pharmacokinetic (PK) Enhancing.” The additional text describes the roles and mechanisms of ritonavir (RTV) and cobicistat (COBI) as pharmacokinetic enhancers to increase the exposure of antiretroviral drugs.
  • Tables 14–16c have been updated with new pharmacokinetic interaction data, including known and predicted interactions involving EVG/COBI/TDF/FTC and other drugs.

Additional Updates
Minor revisions have also been made to the following sections:

  • Introduction

Obama Seeks 'AIDS-Free Generation' in State of the Union

President Barack Obama included AIDS in his first State of the Union speech after his reelection: “In many places, people live on little more than a dollar a day. So the United States will join with our allies to eradicate such extreme poverty in the next two decades by connecting more people to the global economy; by empowering women; by giving our young and brightest minds new opportunities to serve; and helping communities to feed, and power, and educate themselves; by saving the world’s children from preventable deaths; and by realizing the promise of an AIDS-free generation, which is within our reach.”

CHIPTS Investigator in the News: Social media may prove useful in prevention of HIV, STDs, study shows

By Enrique Rivero February 06, 2013
Facebook and other social networking technologies could serve as effective tools for preventing HIV infection among at-risk groups, new UCLA research suggests.
In a study published in the February issue of the peer-reviewed journal Sexually Transmitted Diseases, researchers found that African American and Latino men who have sex with men voluntarily used health-related Facebook groups, which were created by the study’s investigators, to discuss such things as HIV knowledge, stigma and prevention and ultimately to request at-home HIV testing kits.
“Researchers, policymakers and public health professionals are hoping that social media can be used as a tool for improving health research and solving health and HIV prevention–related issues,” said principal investigator Sean Young, an assistant professor of family medicine at the David Geffen School of Medicine at UCLA. “This study helps direct us toward that goal by suggesting that participants will use social media to learn about HIV prevention and that those who talk about HIV prevention over social networking groups are not just talking about it — they are acting on their words by getting an HIV test.”
The study also demonstrates that social networking can be a useful tool for collecting and analyzing data, added Young, who is a member of the Center for HIV Identification, Prevention and Treatment Services (CHIPTS) at UCLA.
“Having one platform that allows multiple types of data collection and analysis can save money and improve the accuracy of research findings,” he said.
The researchers recruited African American and Latino men who have sex with men, either through banner ads placed on social networking sites such as Facebook and MySpace, through a Facebook fan page with study information, through banner ads and posts on Craigslist, and from venues such as bars, schools, gyms and community organizations in Los Angeles. They also recruited study subjects from other population groups to add diversity to the study group.
African American men who have sex with men have been shown to have a disproportionately high risk of becoming infected with HIV, and Latino men are also at high risk, the researchers said.
In total, 112 participants were recruited, nearly 90 percent of whom were African American or Latino, for the 12-week intervention and one-year follow-up after. The average age was 31.
Participants were randomly assigned on Facebook to either a general health group or a secret HIV-prevention group — one that could not be accessed or searched for by non-group members.
The researchers found that participants in the HIV-prevention group freely discussed HIV-related topics such as prevention, testing, knowledge, stigma and advocacy. Those over the age of 31 were more likely to discuss prevention, testing, stigma and advocacy topics, while younger members were more interested in HIV knowledge–related discussions.
In addition, participants who posted about prevention and testing had over 11 times the odds of requesting an HIV testing kit than participants who did not discuss those topics.
Given that all the study participants were from Los Angeles, the findings may not apply to men from other areas, the researchers noted.
Still, the findings suggest that social networking technologies can help increase HIV and STD-related communication among African American and Latino men who have sex with men.
“Participants frequently and willingly used social networking groups to initiate HIV-related conversations, and HIV/STD prevention–related conversations were associated with increased requests for home-based HIV tests,” the researchers write. “As social networking usage continues to grow among at-risk populations, it becomes important to understand how to use these innovative and engaging social technologies for population-focused STD prevention.”
Devan Jaganath, a medical student at the David Geffen School of Medicine at UCLA,co-authored the study.
The National Institute of Mental Health (1 K01 MH090884) funded the research, with additional support from CHIPTS and the UCLA AIDS Institute.
The UCLA Department of Family Medicine provides comprehensive primary care to entire families, from newborns to seniors. It provides low-risk obstetrical services and prenatal and inpatient care at UCLA Medical Center, Santa Monica, and outpatient care at the University Family Health Center in Santa Monica and the Mid-Valley Family Health Center, located in a Los Angeles County Health Center in Van Nuys, Calif. The department is also a leader in family medicine education, for both medical students and residents, and houses a significant research unit focusing on health care disparities among immigrant families and minority communities and other underserved populations in Los Angeles and California.
The Center for HIV Identification, Prevention, and Treatment Services (CHIPTS) is a collaboration involving researchers from UCLA, Charles Drew University of Medicine and Science, the Friends Research Institute, the RAND Corp. and the broader Los Angeles community. It aims to enhance the collective understanding of HIV research and to promote early detection, effective prevention and treatment programs for HIV. Funded by the National Institute of Mental Health, CHIPTS serves as a bridge among researchers, the government, service providers and people with HIV in responding to changes in the HIV epidemic and in shaping sound public policy. This is accomplished through a range of services, including consultation on the development of new research projects and assistance with obtaining funds for these initiatives. CHIPTS provides technical assistance in HIV program development and evaluation and sponsors an annual conference for researchers to present their work. In addition, the center hosts an annual policy forum for researchers, government officials and the HIV community to discuss emerging HIV policy issues and hosts a research colloquia series.
The UCLA AIDS Institute, established in 1992, is a multidisciplinary think tank drawing on the skills of top-flight researchers in the worldwide fight against HIV and AIDS, the first cases of which were reported in 1981 by UCLA physicians. Institute members include researchers in virology and immunology, genetics, cancer, neurology, ophthalmology, epidemiology, social sciences, public health, nursing and disease prevention. Their findings have led to advances in treating HIV, as well as other diseases, such as hepatitis B and C, influenza and cancer.

AIDS United Announces Investments in 6 Puerto Rico Organizations for HIV Prevention Programs

WASHINGTON.  January 30, 2013 – Thanks to $155K in grant investments from AIDS United, six community-based organizations in Puerto Rico will have expanded capacity for vital HIV prevention services in one of the most disproportionately-affected areas in the United States and its territories.  The support from AIDS United comes from a funding partnership with Johnson & Johnson, H. van Ameringen Foundation, MAC AIDS Fund, Merck Corporation, and Elton John AIDS Foundation.

The projects receiving AIDS United support include peer‐based, in-person education and counseling outreach; syringe services programs; and social media outreach, designed to reach the populations most highly impacted by the epidemic on the island, including injection drug users, women, homeless individuals and youth, particularly young men who have sex with men, (MSM).  According to the Centers for Disease Control and Prevention (CDC), in 2010, Puerto Rico ranked in the top 10 AIDS case rates among all states and territories in 2010; had an HIV death rate higher than any U.S. state or territory; and had a rate of HIV infection of 33.8, compared with the United States’ total rate of HIV infection of 19.7.

“These new investments help further AIDS United’s longstanding commitment to addressing the disproportionate severity of the HIV epidemic in Puerto Rico,” said Michael J. Kaplan, AIDS United President and CEO.  “Through this unique funding pool, more than $675K has been invested since 2008. We are continuously communicating with community‐based organizations and advocates about how we might best meet the HIV prevention programming needs there.  Ensuring that Puerto Rico has the resources and the capacity-building assistance it needs to aggressively respond to HIV brings AIDS United even closer to fulfilling our mission to end the HIV epidemic in the United States.”

The Puerto Rico grantees are:

  • Family Planning Association of Puerto Rico / PROFAMILIA, Ponce, PR
    For a “train-the-trainer” program in the southwestern region of Puerto Rico. The program will educate former participants how to conduct outreach and programming for sexual and reproductive health services and work with vulnerable and resource-deprived communities.
  • Hogar Fortaleza del Caido, Loíza, PR
    To coordinate with community leaders in Loíza and Canóvanas to conduct outreach activities to male and female injection drug users and/or homeless individuals. By providing HIV prevention education and counseling session, the program aims to reduce stigma associated with HIV/AIDS and promote healthy behaviors and lifestyles.
  • Migrant Health Center, Mayagüez, PR
    For a Syringe Exchange Project in the Western region of Puerto Rico that will provide a place for injection drug users to dispose of used syringes and obtain sterile syringes at no cost; related prevention, counseling, and care services will also be provided.
  • Puerto Rico Community Network for Clinical Research on AIDS, San Juan, PR
    In support of a peer outreach program for young men that have sex with men (YMSM) from 13 to 29 years old from the San Juan Metropolitan Area that will use social networking, smart phone apps, LGBTT-oriented forums, and traditional outreach at high-risk venues as recruitment strategies for HIV prevention education and testing.
  • Sistema Universitario Ana G. Mendez – Main Campus, Turabo, PR
    To expand the impact of the MSI Prevention Program (PASOS) Initiative that works to directly increase access to comprehensive, integrated substance abuse (SA), and HIV prevention, and early detection at the University of Turabo’s Main Campus. Graduate students of the Psychology program will offer compulsory HIV prevention modules to all freshman students in their Freshman Seminar Course as part of the health promotion section of the course.
  • Taller Salud, Loíza, PR
    To train youth peer health educators in developing creative strategies that encourage HIV/STI prevention as a real alternative for youth and provide resources that increase young people’s capacity to make responsible decisions when confronted with situations that involve sexuality and HIV/STI risk; venues include local discussion forums, a live webcast, and theater productions.

Health Centers Not Routinely Testing for HIV

 

By David Pittman, Washington Correspondent, MedPage Today

Published: January 15, 2013

WASHINGTON — Only one in five federally funded safety-net health centers reported testing all patients ages 13 to 64 for HIV, despite a 7-year-old CDC recommendation to do so, a government report found.

Another 55% reported targeting high-risk patients for testing, the Department of Health and Human Services Office of Inspector General (OIG) stated in a report issued Monday. The high-risk testing is an approach aligning with recommendations from the U.S. Preventive Services Task Force.

Another 1% of sites reported testing all adults, but not teens. The remaining 24% of sites offered HIV tests only when patients requested it or had HIV symptoms, the report found.

The health centers, all of which received money from the federal Health Resources and Services Administration (HRSA), reported a lack of financial resources from patients and sites as one factor that limited their HIV testing.

“Respondents from one health center site reported that patients who were not eligible for free HIV tests were unlikely to pay for tests, and respondents from another health center site reported that patients had difficulty paying even the small office visit fee, let alone an additional testing fee,” the report said.

For its report, the OIG selected a random 500 health centers from among more than 8,100 sites that were receiving HRSA funding in November 2010. Of those, 149 were excluded because they did not provide primary care, they were no longer in operation, or their contractors did not respond to the OIG’s inquiries.

Of the remaining 351 eligible sites, the OIG received responses from 324. Those sites were surveyed from May 2011 to November 2011 on their compliance with four CDC recommendations from 2006 on HIV testing.

The recommendations significantly changed how primary care providers should provide HIV tests. The recommendations for providers — aimed to reduce the stigma of such testing and increase the number of people who know their status — included:

  • Test all patients age 13 to 64 unless the patient has been previously tested for HIV or the prevalence of undiagnosed HIV is less than 0.1%.
  • Don’t perform prevention counseling for all patients, because it is too time-consuming and causes them to be uncomfortable, which could limit testing.
  • Offer consent for HIV tests in the same way as for other screening and diagnostic tests.
  • Present HIV testing as a standard of practice for all patients unless they decline it, rather than making it an “opt-in” test.

 

A study published in November in Annals of Internal Medicine found that routine HIV screening has the potential to reduce sexual transmission of the virus.

The report also found that 29% of sites adopted the CDC’s recommended practice of not offering prevention counseling. When it came to gaining patient consent for HIV testing as with other tests, 27% adopted the practice, and 15% provided an HIV test as a standard, opt-out test, the report found.

HRSA funds grantees that administer clinics for community health, migrant health, homeless health, and public housing primary care. In 2011, such sites provided care to more than 17 million patients, and, with the CDC estimating one in five people in the U.S. living with HIV doesn’t know his status, HRSA centers can play a critical role in reducing the transmission of the virus, the OIG said.

To spur compliance with the CDC’s recommendations, the OIG recommended that HRSA require its health centers to determine the prevalence of undiagnosed HIV in the patient populations, adding that the agency also should require centers to report on their progress in determining prevalence.

Although the CDC recommends against routine testing if the prevalence is less than 0.1%, few health centers in the report tested enough patients to establish such a benchmark.

While they work to establish their patient populations’ HIV prevalence, health centers should also be required by HRSA to report the number of patients who have tested positive among all those tested at the site, the OIG recommended.

HRSA already requires its centers to report the number of tests provided. “However, HRSA does not collect information about how many of those HIV tests resulted in HIV-positive diagnoses,” Monday’s report noted.

HRSA does require clinics that receive funding through the Ryan White HIV/AIDS program — a HRSA program for HIV-positive patients who can’t afford care — track certain performance measures regarding HIV testing and care. “However, this requirement does not cover health center grantees that do not receive such funding,” the report said.

Predicting survival among those aging with HIV infection

By Helen Dodson
January 28, 201

A new collaborative study led by Yale, the VA Healthcare System, and the North American Cohort Collaboration supports the accuracy of an index used for predicting mortality as patients with HIV age. The study appears in the Journal of Acquired Immune Deficiency Syndromes (JAIDS).

The course of chronic HIV infection has changed with the advent of antiretroviral therapy (ART). Viral suppression is common, the authors write, and there have been reductions in AIDS-related deaths in regions where ART is easily accessible. Yet, the authors say, people with HIV infection continue to experience a higher rate of mortality due not just to HIV-related factors, but because chronic HIV infection appears to exacerbate vulnerability to aging-related organ system injury.

The Veterans Aging Cohort Study (VACS) Index, funded by the National Institutes of Health (NIH), builds upon older indices that measured biomarkers for HIV (the virus that causes AIDS) — such as CD4 cell count, HIV-1 RNA levels, and patient age —  in order to determine mortality risk. The newer VACS Index takes other critical factors into account, such as the increasing role of multi-organ system injury and hepatitis C infection, and the decreasing role of other factors such as CD4 count.

The researchers analyzed data from over 5,000 veterans and over 10,000 non-veterans representing 14 separate cohorts of HIV-infected patients around the country who had had at least a year of exposure to ART. They followed up with those patients for just over three years. Researchers found the new VACS index to be much more accurate and effective than an index restricted to CD4 count, HIV-1 RNA, and age.

According to senior author Dr. Amy Justice, professor of internal medicine at Yale School of Medicine, “The VACS Index accurately estimates risk of mortality among those aging with HIV infection whether they live in Canada or the United States. Further, it is accurate among men and women, those who are older and younger, and white individuals and people of color.” The team has developed an app that allows patients and their providers to use this information in care. It can be accessed online.

Justice is professor of medicine and public health at Yale School of Medicine; she also serves as section chief of general internal medicine in the VA Connecticut Healthcare System and is affiliated with Yale’s Center for Interdisciplinary Research on AIDS.

This study was supported by grants from the National Institutes of Health. Other funding was provided by the Training Program in Environmental Epidemiology, and other grants from the NIH. This work was also supported by the Centers for Disease Control, the Canadian Institutes for Health Research, and the Canadian Trials Network.
