The number of people infected with HIV or living with AIDS is increasing at unprecedented rates as various scientists, organizations, and institutions search for innovative solutions to combating and preventing the disease. At the request of the Bill & Melinda Gates Foundation, Methodological Challenges in Biomedical HIV Prevention Trials addresses methodological challenges in late-stage nonvaccine biomedical HIV prevention trials with a specific focus on microbicide and pre-exposure prophylaxis trials. This book recommends a number of ways to improve the design, monitoring, and analysis of late-stage clinical trials that evaluate nonvaccine biomedical interventions. The objectives include identifying a beneficial method of intervention, enhancing quantification of the impact, properly assessing the effects of using such an intervention, and reducing biases that can lead to false positive trial results. According to Methodological Challenges in Biomedical HIV Prevention Trials, the need to identify a range of effective, practical, and affordable preventive strategies is critical. Although a large number of promising new HIV prevention strategies and products are currently being tested in late-stage clinical trials, these trials face a myriad of methodological challenges that slow the pace of research and limit the ability to identify and fully evaluate effective biomedical interventions.

Health is a highly valued, visible, and concrete investment that has the power to both save lives and enhance the credibility of the United States in the eyes of the world. While the United States has made a major commitment to global health, there remains a wide gap between existing knowledge and tools that could improve health if applied universally, and the utilization of these known tools across the globe. The U.S. Commitment to Global Health concludes that the U.S. government and U.S.-based foundations, universities, nongovernmental organizations, and commercial entities have an opportunity to improve global health. The book includes recommendations that these U.S. institutions: increase the utilization of existing interventions to achieve significant health gains; generate and share knowledge to address prevalent health problems in disadvantaged countries; invest in people, institutions, and capacity building with global partners; increase the quantity and quality of U.S. financial commitments to global health; and engage in respectful partnerships to improve global health. In doing so, the U.S. can play a major role in saving lives and improving the quality of life for millions around the world.
Randomized clinical trials are the primary tool for evaluating new medical interventions. Randomization provides for a fair comparison between treatment and control groups, balancing out, on average, distributions of known and unknown factors among the participants. Unfortunately, these studies often lack a substantial percentage of data. This missing data reduces the benefit provided by the randomization and introduces potential biases in the comparison of the treatment groups. Missing data can arise for a variety of reasons, including the inability or unwillingness of participants to meet appointments for evaluation. And in some studies, some or all of data collection ceases when participants discontinue study treatment. Existing guidelines for the design and conduct of clinical trials, and the analysis of the resulting data, provide only limited advice on how to handle missing data. Thus, approaches to the analysis of data with an appreciable amount of missing values tend to be ad hoc and variable. The Prevention and Treatment of Missing Data in Clinical Trials concludes that a more principled approach to design and analysis in the presence of missing data is both needed and possible. Such an approach needs to focus on two critical elements: (1) careful design and conduct to limit the amount and impact of missing data and (2) analysis that makes full use of information on all randomized participants and is based on careful attention to the assumptions about the nature of the missing data underlying estimates of treatment effects. In addition to the highest priority recommendations, the book offers more detailed recommendations on the conduct of clinical trials and techniques for analysis of trial data.
Mother-to-child transmission of HIV-1 afflicts hundreds of thousands of children every year, especially in parts of the world such as sub-Saharan Africa, where HIV infection is prevalent and resources are limited. This tragic reality has spurred researchers to search for an effective, safe, and inexpensive treatment that could reduce the risk of perinatal HIV transmission. The HIVNET 012 trial was designed to provide preliminary information on the comparative safety and efficacy of two relatively simple and inexpensive short courses of oral antiretroviral treatment likely to be feasible in resource-limited settings. The resulting report identified some problems with procedures and documentation, but concluded that these issues did not compromise the results of the study. However, these issues have led to public scrutiny and continued controversy. Review of the HIVNET 012 Perinatal HIV Prevention Study critically and objectively evaluates the study's design and conduct, and assesses the impact of the initial procedural issues on the validity of the overall findings and conclusions of the trial.
At a time when lesbian, gay, bisexual, and transgender individuals-often referred to under the umbrella acronym LGBT-are becoming more visible in society and more socially acknowledged, clinicians and researchers are faced with incomplete information about their health status. While LGBT populations often are combined as a single entity for research and advocacy purposes, each is a distinct population group with its own specific health needs. Furthermore, the experiences of LGBT individuals are not uniform and are shaped by factors of race, ethnicity, socioeconomic status, geographical location, and age, any of which can have an effect on health-related concerns and needs. The Health of Lesbian, Gay, Bisexual, and Transgender People assesses the state of science on the health status of LGBT populations, identifies research gaps and opportunities, and outlines a research agenda for the National Institute of Health. The report examines the health status of these populations in three life stages: childhood and adolescence, early/middle adulthood, and later adulthood. At each life stage, the committee studied mental health, physical health, risks and protective factors, health services, and contextual influences. To advance understanding of the health needs of all LGBT individuals, the report finds that researchers need more data about the demographics of these populations, improved methods for collecting and analyzing data, and an increased participation of sexual and gender minorities in research. The Health of Lesbian, Gay, Bisexual, and Transgender People is a valuable resource for policymakers, federal agencies including the National Institute of Health (NIH), LGBT advocacy groups, clinicians, and service providers.
HIV is spreading rapidly, and effective treatments continue to elude science. Preventive interventions are now our best defense against the epidemicâ€"but they require a clear understanding of the behavioral and mental health aspects of HIV infection and AIDS. AIDS and Behavior provides an update of what investigators in the biobehavioral, psychological, and social sciences have discovered recently about those aspects of the disease and offers specific recommendations for research directions and priorities. This volume candidly discusses the sexual and drug-use behaviors that promote transmission of HIV and reports on the latest efforts to monitor the epidemic in its social contexts. The committee reviews new findings on how and why risky behaviors occur and efforts to develop strategies for changing such behaviors. The volume presents findings on the disease's progression and on the psychosocial impacts of HIV and AIDS, with a view toward intervention and improved caregiving. AIDS and Behavior also evaluates the status of behavioral and prevention aspects of AIDS research at the National Institute of Mental Health, the National Institute on Drug Abuse, and the National Institute on Alcohol Abuse and Alcoholism. The volume presents background on the three institutes; their recent reorganization; their research budgets, programs, and priorities; and other important details. The committee offers specific recommendations for the institutes concerning the balance between biomedical and behavioral investigations, adequacy of administrative structures, and other research management issues. Anyone interested in the continuing quest for new knowledge on preventing HIV and AIDS will want to own this book: policymakers, researchers, research administrators, public health professionals, psychologists, AIDS advocates and service providers, faculty, and students.
In the nineteenth century some scientists argued that women should not be educated because thinking would use energy needed by the uterus for reproduction. The proof? Educated women had a lower birth rate. Today's researchers can only shake their heads at such reasoning. Yet professional journals and the popular press are increasingly criticizing medical research for ignoring women's health issues. Women and Health Research examines the facts behind the public's perceptions about women participating as subjects in medical research. With the goal of increasing researchers' awareness of this important topic, the book explores issues related to maintaining justice (in its ethical sense) in clinical studies. Leading experts present general principles for the ethical conduct of research on womenâ€"principles that are especially important in the light of recent changes in federal policy on the inclusion of women in clinical research. Women and Health Research documents the historical shift from a paternalistic approach by researchers toward women and a disproportionate reliance on certain groups for research to one that emphasizes proper access for women as subjects in clinical studies in order to ensure that women receive the benefits of research. The book addresses present-day challenges to equity in four areas: Scientificâ€"Do practical aspects of scientific research work at cross-purposes to gender equity? Focusing on drug trials, the authors identify rationales for excluding people from research based on demographics. Social and Ethicalâ€"The authors offer compelling discussions on subjectivity in science, the evidence for male bias, and issues related to race and ethnicity, as well as the recruitment, retention, and protection of research participants. Legalâ€"Women and Health Research reviews federal research policies that affect the inclusion of women and evaluates the basis for researchers' fears about liability, citing court cases. Riskâ€"The authors focus on risks to reproduction and offspring in clinical drug trials, exploring how risks can be identified for study participants, who should make the assessment of risk and benefit for participation in a clinical study, and how legal implications could be addressed. This landmark study will be of immediate use to the research community, policymakers, women's health advocates, attorneys, and individuals.
An estimated forty million people carry the human immunodeficiency virus (HIV), and five million more become newly infected annually. In recent years, many HIV-infected patients in wealthy nations have enjoyed significantly longer, good-quality lives as a result of antiretroviral therapy (ART). However, most infected individuals live in the poorest regions of the world, where ART is virtually nonexistent. The consequent death toll in these regionsâ€"especially sub-Saharan Africaâ€"is begetting economic and social collapse. To inform the multiple efforts underway to deploy antiretroviral drugs in resource-poor settings, the Institute of Medicine committee was asked to conduct an independent review and assessment of rapid scale-up ART programs. It was also asked to identify the components of effective implementation programs. At the heart of the committee's report lie five imperatives: Immediately introduce and scale up ART programs in resource-poor settings. Devise strategies to ensure high levels of patient adherence to complicated treatment regimens. Rapidly address human-resource shortages to avoid the failure of program implementation. Continuously monitor and evaluate the programs to form the most effective guidelines and treatment regimens for each population. Prepare to sustain ART for decades.
More than 200,000 people in the United States living with HIV/AIDS do not know they are infected. The Institute of Medicine's Committee on HIV Screening and Access to Care held a workshop and reviewed literature to explore barriers and facilitators to more widespread HIV testing. This book contains the committee's conclusions.
SMART Vaccines--Strategic Multi-Attribute Ranking Tool for Vaccines--is a prioritization software tool developed by the Institute of Medicine that utilizes decision science and modeling to help inform choices among candidates for new vaccine development. A blueprint for this computer-based guide was presented in the 2012 report Ranking Vaccines: A Prioritization Framework: Phase I. Ranking Vaccines: A Prioritization Software Tool,Phase II extends the proof-of-concept presented in the Phase I report, which was based on multi-attribute utility theory. This report refines a beta version of the model developed in the Phase I report and presents its next iteration, SMART Vaccines 1.0. Ranking Vaccines: Phase II discusses the methods underlying the development, validation, and evaluation of SMART Vaccines 1.0. It also discusses how SMART Vaccines should--and, just as importantly, should not--be used. The report also offers ideas for future enhancements for SMART Vaccines as well as for ideas for expanded uses and considerations and possibilities for the future.
Cancer care today often provides state-of-the-science biomedical treatment, but fails to address the psychological and social (psychosocial) problems associated with the illness. This failure can compromise the effectiveness of health care and thereby adversely affect the health of cancer patients. Psychological and social problems created or exacerbated by cancer-including depression and other emotional problems; lack of information or skills needed to manage the illness; lack of transportation or other resources; and disruptions in work, school, and family life-cause additional suffering, weaken adherence to prescribed treatments, and threaten patients' return to health. Today, it is not possible to deliver high-quality cancer care without using existing approaches, tools, and resources to address patients' psychosocial health needs. All patients with cancer and their families should expect and receive cancer care that ensures the provision of appropriate psychosocial health services. Cancer Care for the Whole Patient recommends actions that oncology providers, health policy makers, educators, health insurers, health planners, researchers and research sponsors, and consumer advocates should undertake to ensure that this standard is met.
In recent decades, advances in biomedical research have helped save or lengthen the lives of children around the world. With improved therapies, child and adolescent mortality rates have decreased significantly in the last half century. Despite these advances, pediatricians and others argue that children have not shared equally with adults in biomedical advances. Even though we want children to benefit from the dramatic and accelerating rate of progress in medical care that has been fueled by scientific research, we do not want to place children at risk of being harmed by participating in clinical studies. Ethical Conduct of Clinical Research Involving Children considers the necessities and challenges of this type of research and reviews the ethical and legal standards for conducting it. It also considers problems with the interpretation and application of these standards and conduct, concluding that while children should not be excluded from potentially beneficial clinical studies, some research that is ethically permissible for adults is not acceptable for children, who usually do not have the legal capacity or maturity to make informed decisions about research participation. The book looks at the need for appropriate pediatric expertise at all stages of the design, review, and conduct of a research project to effectively implement policies to protect children. It argues persuasively that a robust system for protecting human research participants in general is a necessary foundation for protecting child research participants in particular.
Breakthroughs in biomedicine often lead to new life-giving treatments but may also raise troubling, even life-and-death, quandaries. Society's Choices discusses ways for people to handle today's bioethics issues in the context of America's unique history and culture--and from the perspectives of various interest groups. The book explores how Americans have grappled with specific aspects of bioethics through commission deliberations, programs by organizations, and other mechanisms and identifies criteria for evaluating the outcomes of these efforts. The committee offers recommendations on the role of government and professional societies, the function of commissions and institutional review boards, and bioethics in health professional education and research. The volume includes a series of 12 superb background papers on public moral discourse, mechanisms for handling social and ethical dilemmas, and other specific areas of controversy by well-known experts Ronald Bayer, Martin Benjamin, Dan W. Brock, Baruch A. Brody, H. Alta Charo, Lawrence Gostin, Bradford H. Gray, Kathi E. Hanna, Elizabeth Heitman, Thomas Nagel, Steven Shapin, and Charles M. Swezey.
