Project description:BackgroundInfant feeding in the context of human immunodeficiency virus (HIV) poses unique challenges to mothers and healthcare workers in balancing the perceived risks of HIV transmission and nutritional requirements. We aimed to describe the decision-making processes around infant feeding at a rural HIV clinic in Kenya.MethodsWe used a qualitative study design. Between March and August 2011, we conducted in-depth interviews (n = 9) and focus group discussions (n = 10) with purposively selected hospital and community respondents at Kilifi County Hospital, Kenya. These respondents had all experienced of infant feeding in the context of HIV. These interviews were informed by prior structured observations of health care worker interactions with carers during infant feeding counselling sessions.ResultsOverall, women living with HIV found it difficult to adhere to the HIV infant feeding guidance. There were three dominant factors that influenced decision making processes: 1) Exclusive breastfeeding was not the cultural norm, therefore practising it raised questions within the family and community about a mother's parenting capabilities and HIV status. 2) Women living with HIV lacked autonomy in decision-making on infant feeding due to socio-cultural factors. 3) Non-disclosure of HIV status to close members due to the stigma.ConclusionInfant feeding decision-making by women living with HIV in rural Kenya is constrained by a lack of autonomy, stigma and poverty. There is an urgent need to address these challenges through scaling up psycho-social and gender empowerment strategies for women, and introducing initiatives that promote the integration of HIV infant feeding strategies into other child health services.

Project description:We conducted three focus groups to examine African American women's perceptions of factors influencing and proposed strategies for reducing sedentary behavior (SB). QSR NVivo 9 facilitated coding and organization of themes. Although participants ( n = 32, 53.6 ± 6.0 years, 75% obese) were unfamiliar with the term SB prior to focus groups, they described spending large amounts of time in SB at work and home. Participants viewed leisure-time SB as necessary and important but were amenable to decreasing SB at work. Participants also identified personal, social, and environmental factors contributing to SB as well as novel strategies for reducing SB. Results suggest that messages aimed at reducing SB in African American women should be positively framed, viewed within a socioecologic framework, and target nonleisure time SB. SB was viewed as a form of stress reduction; thus, future research might want to emphasize alternative stress management techniques that simultaneously reduce SB.

Project description:HIV-testing algorithms for preexposure prophylaxis (PrEP) should be optimized to minimize the risk of drug resistance, the time off PrEP required to evaluate false-positive screening results, and costs and to expedite the start of therapy for those confirmed to be infected. HIV rapid tests (RTs) for anti-HIV antibodies provide results in less than 1 h and can be conducted by nonlicensed staff at the point of care. In many regions, Western blot (WB) testing is required to confirm reactive RT results. WB testing, however, causes delays in diagnosis and adds expense. The iPrEx study evaluated the safety and efficacy of daily oral emtricitabine-tenofovir disoproxil fumarate among HIV-seronegative men and transgender women who have sex with men: HIV infection was assessed with two RTs plus WB confirmation, followed by HIV-1 plasma viral load testing. During the iPrEx study, there were 51,260 HIV status evaluations among 2,499 volunteers using RTs: 142 (0.28%) had concordant positive results (100% were eventually confirmed) and 19 (0.04%) had discordant results among 14 participants; 11 were eventually determined to be HIV infected. A streamlined approach using only one RT to screen and a second RT to confirm (without WB) would have had nearly the same accuracy. Discrepant RT results are best evaluated with nucleic acid testing, which would also increase sensitivity.

Project description:ObjectiveThe aim of this study was to appropriately plan for rollout and monitor impact of oral preexposure prophylaxis (PrEP). It is important to understand PrEP continuation and come to a consensus on how best to measure PrEP continuation. This study reviews data on PrEP continuation to document how it is reported, and to compare continuation over time and across populations.DesignA systematic review and meta-analysis.MethodsWe searched MEDLINE, Embase and Global Health and reviewed abstracts from HIV conferences from 2017 to 2018 for studies reporting primary data on PrEP continuation. Findings were summarized along a PrEP cascade and continuation was presented by population at months 1, 6 and 12, with random-effects meta-analysis.ResultsOf 2578 articles and 596 abstracts identified, 41 studies were eligible covering 22 034 individuals. Continuation data were measured and reported inconsistently. Results showed high discontinuation at month 1 and persistent discontinuation at later time points in many studies. Pooled continuation estimates were 66% at month 1 [n = 5348; 95% confidence interval (95% CI): 48-82], 63% at month 6 (n = 13 629; 95% CI: 48-77) and 71% at month 12 (n = 14 933; 95% CI: 60-81; higher estimate than previous timepoints due to inclusion of different studies). Adequate data were not available to reliably compare estimates across populations.ConclusionThis review found that discontinuation at one month was high, suggesting PrEP initiations may be a poor measure of effectiveness. Continuation declined further over time in many studies, indicating existing cross-sectional indicators may not be adequate to understand PrEP use patterns. Studies do not measure continuation consistently, and consensus is needed.

Project description:PurposeAtypical hyperplasia (AH) is associated with a nearly 4-fold elevation of lifetime risk for breast cancer, and lobular carcinoma in situ (LCIS) is associated with a 7- to 8-fold risk. Women with AH/LCIS make numerous decisions in the course of treatment, including whether to take a risk-reducing medication, an option relatively few women pursue. We explored women's decision-making processes through patient narratives in an effort to inform decision supports for AH/LCIS.MethodsWe conducted in-depth interviews with 20 English-speaking women with AH/LCIS and no subsequent diagnosis of invasive breast cancer who had enrolled in the Rays of Hope Center for Breast Cancer Research patient registry between April 5, 2012, and March 31, 2016. Interviews were audiotaped, professionally transcribed, and qualitatively analyzed using thematic qualitative content analysis.ResultsWe identified three major narrative themes: 1) experiences with medical care; 2) decision-making; and 3) making sense of AH/LCIS. Each major theme had several subthemes, many of which map onto existing decisional theories and heuristics. Subthemes included the impact of life context on diagnosis meaning, emotional responses, changes in self-concept and body image, and understanding of the risk-benefit of risk-reducing medications.ConclusionsThis narrative analysis offers important insights into how lived experience may influence decision-making for women with AH/LCIS. Decision supports that focus not only on analytic decisional processes, but also patients' subjectivities and decisional heuristics, could prove useful for women and their health care providers.

Project description:Clinical trials of oral preexposure prophylaxis (PrEP) have focused on regimens of tenofovir (TDF) with or without emtricitabine (FTC). However, TDF may be associated with toxicities (renal, bone), and FTC may select for drug resistance. Both are also first-line drugs for HIV treatment. In this review, we discuss agents that might serve as alternatives to TDF/FTC for HIV PrEP.Several drug characteristics are important to consider when selecting agents for PrEP with the most critical being safety, tolerability, adequate penetration into target tissues for prevention of HIV infection, and long-lasting activity with convenient dosing. With these factors in mind, we review five potentially useful agents for PrEP. The first group includes drugs that are already Food and Drug Administration approved (maraviroc, raltegravir) with attributes that make them attractive for PrEP. The second group includes investigational agents with long-lasting activity that are being developed in parenteral form (rilpivirine-long acting, S/GSK1265744, ibalizumab).Future PrEP drugs may give clinicians the flexibility to select agents on the basis of individual patient needs and preferences.

Project description:BackgroundPreexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others.MethodsIn this randomized, double-blind, placebo-controlled trial, we assigned 2120 HIV-negative women in Kenya, South Africa, and Tanzania to receive either a combination of tenofovir disoproxil fumarate and emtricitabine (TDF-FTC) or placebo once daily. The primary objective was to assess the effectiveness of TDF-FTC in preventing HIV acquisition and to evaluate safety.ResultsHIV infections occurred in 33 women in the TDF-FTC group (incidence rate, 4.7 per 100 person-years) and in 35 in the placebo group (incidence rate, 5.0 per 100 person-years), for an estimated hazard ratio in the TDF-FTC group of 0.94 (95% confidence interval, 0.59 to 1.52; P=0.81). The proportions of women with nausea, vomiting, or elevated alanine aminotransferase levels were significantly higher in the TDF-FTC group (P=0.04, P<0.001, and P=0.03, respectively). Rates of drug discontinuation because of hepatic or renal abnormalities were higher in the TDF-FTC group (4.7%) than in the placebo group (3.0%, P=0.051). Less than 40% of the HIV-uninfected women in the TDF-FTC group had evidence of recent pill use at visits that were matched to the HIV-infection window for women with seroconversion. The study was stopped early, on April 18, 2011, because of lack of efficacy.ConclusionsProphylaxis with TDF-FTC did not significantly reduce the rate of HIV infection and was associated with increased rates of side effects, as compared with placebo. Despite substantial counseling efforts, drug adherence appeared to be low. (Supported by the U.S. Agency for International Development and others; FEM-PrEP ClinicalTrials.gov number, NCT00625404.).

Project description:The review describes the evidence for HIV preexposure prophylaxis (PrEP) with daily combined tenofovir disoproxil fumarate and emtricitabine for adolescents and young adults. Current recommendations are described, as are the unique medical, socioeconomic, and legal considerations regarding the use of PrEP for youth.PrEP with daily oral tenofovir disoproxil fumarate-emtricitabine has been shown to help prevent new HIV infection among adults at substantial risk. Evidence suggests a protective benefit of PrEP for youth at risk for HIV, although low adherence is emerging as a barrier to effective use.Effective use of antiretrovirals for PrEP represents a seminal development in HIV prevention efforts. Improving access and adherence to PrEP for youth has the potential to substantially reduce the incidence of HIV in this population.

Project description:BACKGROUND:Non-Invasive Prenatal Testing (NIPT) is a technology which provides information about fetal genetic characteristics (including sex) very early in pregnancy by examining fetal DNA obtained from a sample of maternal blood. NIPT is a morally complex technology that has advanced quickly to market with a strong push from industry developers, leaving many areas of uncertainty still to be resolved, and creating a strong need for health policy that reflects women's social and ethical values. We approach the need for ethical policy-making by studying the use of NIPT and emerging policy in the province of Ontario, Canada. METHODS:Using an adapted version of constructivist grounded theory, we conducted interviews with 38 women who have had personal experiences with NIPT. We used an iterative process of data collection and analysis and a staged coding strategy to conduct a descriptive analysis of ethics issues identified implicitly and explicitly by women who have been affected by this technology. RESULTS:The findings of this paper focus on current ethical issues for women seeking NIPT, including place in the prenatal pathway, health care provider counselling about the test, industry influence on the diffusion of NIPT, consequences of availability of test results. Other issues gain relevance in the context of future policy decisions regarding NIPT, including funding of NIPT and principles that may govern the expansion of the scope of NIPT. These findings are not an exhaustive list of all the potential ethical issues related to NIPT, but rather a representation of the issues which concern women who have personal experience with this test. CONCLUSIONS:Women who have had personal experience with NIPT have concerns and priorities which sometimes contrast dramatically with the theoretical ethics literature. These findings suggest the importance of engaging patients in ethical deliberation about morally complex technologies, and point to the need for more deliberative patient engagement work in this area.
