ABSTRACT
Despite tremendous advances in HIV research, women and gender diverse people-particularly women from racial and ethnic groups under-represented in research, transgender women, and young women-remain disproportionately affected by HIV. Women and gender diverse people face unique challenges and have been under-represented in HIV research. The National Institutes of Health (NIH) is tasked to apply fundamental knowledge about the nature and behaviour of living systems to enhance health, lengthen life, and reduce disability. Rigorous exploration of-and interventions for-the individual, social, biological, structural, and environmental factors that influence HIV prevention, transmission, treatment, and cure is crucial to advance research for women, girls, and gender diverse people across the lifespan. In this Position Paper, we introduce a framework for an intersectional, equity-informed, data-driven approach to research on HIV and women and highlight selected issues for women and gender diverse people, including HIV prevention, HIV cure, ageing with HIV, substance use and misuse, violence, pregnancy, and breastfeeding or chestfeeding. This framework underlines a new HIV and Women Signature Programme from the NIH Office of AIDS Research and Office of Research on Women's Health that advances the NIH vision for women's health, in which all women receive evidence-based HIV prevention, treatment, and care across their lifespan tailored to their unique needs, circumstances, and goals. The time is now to centre the health of women, girls, and gender diverse people across the HIV research continuum.

ABSTRACT: In 2019, approximately 1.2 M persons were living with HIV and an estimated 34,800 new HIV infections occurred in the United States (U.S.). Significant disparities in HIV burden exist among persons of color, those with male-to-male sexual contact, young people, and persons experiencing barriers to consistent uptake of HIV interventions and services. These disparities are the root of major gaps in coverage of HIV testing, linkage to prevention and treatment, adherence, and retention in services in the United States. These gaps help fuel the American HIV epidemic. The Ending the HIV Epidemic in the U.S. Initiative (EHE) is built on 4 decades of federal domestic and international responses to HIV/AIDS. As the largest health research agency in the world, the National Institutes for Health (NIH) funds extensive basic, clinical, translational, and implementation HIV research that is crucial to achieving HIV epidemic control. Addressing the gaps and meeting EHE milestones will be accomplished in part through a combination of adaptation, implementation, and scale-up of existing HIV interventions. New discoveries will also be needed to create improved and novel diagnostics, monitor viral loads, and develop new prevention and treatment tools and approaches. HIV implementation research is essential to demonstrate the most effective strategies to facilitate the adaptation, adoption, and integration of evidence-based HIV interventions in real-world settings. This article outlines current NIH research plans to reduce and identify new HIV infections, improve treatment coverage and outcomes among persons with HIV, and effectively respond to HIV transmission outbreaks in the United States.

BACKGROUND: Mobile HIV testing services (HTS) are effective at reaching undiagnosed people living with HIV. However, linkage to HIV care from mobile HTS is often poor, ranging from 10 to 60%. Point-of-care (POC) CD4 testing has shown to increase retention in health facilities, but little evidence exists about their use in mobile HTS. This study assessed the feasibility of POC CD4 test implementation and investigated linkage to HIV care among clients accepting a POC test at community-based mobile HTS. METHODS: This retrospective study used routinely collected data from clients who utilized community-based mobile HTS in the City of Cape Town Metropolitan district, South Africa between December 2014 and September 2016. A POC CD4 test was offered to all clients with an HIV positive diagnosis during this period, and a CD4 cell count was provided to clients accepting a POC CD4 test. Random effects logistic regression was used to assess factors associated with POC CD4 test uptake and self-reported linkage to care among clients accepting a POC test. Models were adjusted for sex, age, previous HIV test done, tuberculosis status and year of HIV diagnosis. RESULTS: One thousand three hundred twenty-five of Thirty-nine thousand seven hundred ninety clients utilizing mobile HTS tested HIV positive (3%). 51% (679/1325) accepted a POC test. The age group with the highest proportion accepting a POC test was 50+ years (60%). Females were less likely to accept a POC test than males (odds ratio = 0.7, 95%CI = 0.6-0.8). Median CD4 count was 429 cells/µl (interquartile range = 290-584). Among 679 clients who accepted a POC CD4 test, 491 (72%) linked to HIV care. CD4 cell count was not associated with linkage to care. CONCLUSION: Our findings suggest that mobile HTS can identify early HIV infection, and show that a high proportion of clients with a POC test result linked to care. Future research should assess factors associated with POC test acceptance and assess the impact of POC CD4 testing in comparison to alternative strategies to engage HIV positive people in care.

OBJECTIVE: To assess participant experiences and perceptions of removal pain and odor associated with the PrePex device procedure. METHODS: We analyzed data from a PrePex device pilot implementation study of 802 male participants aged 18-49 years at 2 clinics in Botswana, 2013. Study staff administered survey questions on device-related odor and assessed pain using visual analog scale scores categorized as no pain (0), mild (1-4), moderate (5-7), or severe pain (8-10). RESULTS: Mean participant age was 27.7 (range = 18-48) years. Of the 802 participants, 751 (94%) reported to have noticed an unusual or unpleasant odor while wearing the device. Of these, 193 (26%) participants tried something to combat the odor. A total of 84 (10%) participants reported no pain, 655 (82%) mild pain, 48 (6%) moderate pain, and 15 (2%) severe pain at 2 minutes after device removal. Pain reports at 15 minutes after removal were 553 (69%) no pain, 247 (31%) mild pain, and 2 (0.25%) moderate pain, with no report of severe pain at this time point. Of 740 participants interviewed on day 42 after device placement, 678 (92%) were satisfied with the procedure and 681 (92%) would recommend it to another man considering circumcision, including 488 (66%) who would recommend it strongly. CONCLUSIONS: An unusual or unpleasant odor while wearing the PrePex device and mild self-limiting pain at device removal were common, but overall, these did neither seem to impair satisfaction nor deter participants from recommending PrePex to others, which could suggest good prospects for uptake of the device in this setting.

BACKGROUND: South Africa has over 6,000,000 HIV infected individuals and the province of KwaZulu-Natal (KZN) is the most severely affected. As public health initiatives to better control the HIV epidemic are implemented, timely, detailed and robust surveillance data are needed to monitor, evaluate and inform the programmatic interventions and policies over time. We describe the rationale and design of the HIV Incidence Provincial Surveillance System (HIPSS) to monitor HIV prevalence and incidence. METHODS/DESIGN: The household-based survey will include a sample of men and women from two sub-districts of the uMgungundlovu municipality (Vulindlela and the Greater Edendale) of KZN, South Africa. The study is designed as two sequential cross-sectional surveys of 10,000 randomly selected individuals aged 15-49 years to be conducted one year apart. From the cross sectional surveys, two sequential cohorts of HIV negative individuals aged 15-35 years will be followed-up one year later to measure the primary outcome of HIV incidence. Secondary outcomes include the laboratory measurements for pulmonary tuberculosis, sexually transmitted infections and evaluating tests for estimating population-level HIV incidence. Antiretroviral therapy (ART) access, HIV-1 RNA viral load, and CD4 cell counts in HIV positive individuals will assess the effectiveness of the HIV treatment cascade. Household and individual-level socio-demographic characteristics, exposure to HIV programmatic interventions and risk behaviours will be assessed as predictors of HIV incidence. The incidence rate ratio of the two cohorts will be calculated to quantify the change in HIV incidence between consecutive samples. In anticipation of better availability of population-level HIV prevention and treatment programmes leading to decreases in HIV incidence, the sample size provides 84% power to detect a reduction of 30% in the HIV incidence rate between surveys. DISCUSSION: The results from HIPSS will provide critical data regarding HIV prevalence and incidence in this community and will establish whether HIV prevention and treatment efforts in a "real world", non-trial setting have an impact on HIV incidence at a population level. Importantly, the study design and methods will inform future methods for HIV surveillance.

In 2006, Ghana ranked second in Guinea worm disease (GWD) incidence and reported a previously undocumented 20% prevalence of worm breakage. A prospective study was conducted in 2007 to validate and describe worm breakage and determinants. Among 221 patients with known outcomes, the worm breakage rate observed was 46%. After controlling for demographics, worm and wound presentation, and treatment course and provision, worm breakage was associated with narrow-diameter worms (< 2 mm) (adjusted odds ratio [AOR] 2.79; 95% confidence interval [CI] = 1.03-7.53). Protective factors against worm breakage included antibiotic ointment use (AOR 0.31; 95% CI = 0.14-0.70), bandage protocol compliance (AOR: 0.38; 95% CI = 0.16-0.89), intact bandages (AOR 0.27; 95% CI = 0.09-0.82), and bloody compared with dry wounds (AOR 0.09; 95% CI = 0.01-0.7). The high worm breakage rate observed warrants improvement in case management and patient care. Adherence to established treatment protocols should be facilitated through improved provider training and supervision to reduce the disabling consequences of broken worms.

BACKGROUND: Terrorist bombings are an increasing source of violent death and injury worldwide. Injuries in building bombings have been previously reported in descriptive studies, but no comparative analyses have quantitatively assessed factors influencing the severity of nonfatal bombing injuries. The objective of this study was to identify personal and environmental risk factors for injury severity in the Oklahoma City bombing, on April 19, 1995. METHODS: We conducted a retrospective comparative analysis of 509 nonfatally injured occupants of four buildings surrounding the detonation site. The source of data was the 1995 Oklahoma City Bombing database, a registry of all injuries and fatalities related to the bombing. Multivariable logistic regression was used to assess two outcomes: (1) medically-attended injury among injured occupants; and (2) hospital admission among occupants with medically attended injuries. RESULTS: Increased odds of sustaining medically attended injuries were associated with being struck by flying glass (adjusted odds ratio [AOR], 5.3; 95% confidence interval [CI], 1.9-14.8) and location above the first floor of buildings (OR, 4.0; 95% CI, 1.4-11.7) after adjustment for other factors. Adjusted odds of hospital admission were associated with location in the collapsed region (AOR, 43.4; 95% CI, 4.4-434.1), being blown by the blast wind (AOR, 5.3; 95% CI, 2.1-13.8), and being trapped (AOR, 3.1; 95% CI, 1.2-7.7). CONCLUSIONS: The severity of nonfatal injury in the Oklahoma bombing was primarily associated with structural and environmental factors. Improved architectural design may prevent many injuries in building bombings. These finding provide evidence for future injury prevention activities.

INTRODUCTION: Bombings, including the 1995 Oklahoma City bombing, remain an important public health threat. However, there has been little investigation into the impressions of injury risk or protective factors of bombing survivors. OBJECTIVE: This study analyzes Oklahoma City bombing survivors' impressions of factors that influenced their risk of injury, and validates a hazard timeline outlining phases of injury risk in a building bombing. METHODS: In-depth, semi-structured interviews were conducted within a sample of Oklahoma City bombing survivors. Participants included 15 injured and uninjured survivors, who were located in three buildings surrounding the detonation site during the attack. RESULTS: Risk factor themes included environmental glass, debris, and entrapment. Protective factors included knowledge of egress routes, shielding behaviors to deflect debris, and survival training. Building design and health status were reported as risk and protective factors. The hazard timeline was a useful tool, but should be modified to include a lay rescue phase. The combination of a narrative approach and direct questioning is an effective method of gathering the perceptions of survivors. CONCLUSIONS: Investigating survivors' impressions of building bombing hazards is critical to capture injury exposures, behavior patterns, and decision-making processes during actual events, and to identify interventions that will be supported by survivors.

BACKGROUND: Bombings are an increasing threat to the public's health. Descriptive studies of blast injuries have been published, but these injuries have not been studied using analytical epidemiological methods. This study assesses factors associated with fatality risk among individuals exposed to the 1995 Oklahoma City bombing. METHODS: Retrospective case-control analysis using multivariable logistic regression. Odds ratios (OR) of fatality are calculated among occupants of the Alfred P. Murrah Federal Building on April 19, 1995. RESULTS: Of the 348 occupants exposed, 163 (46.8%) were fatally injured. Fatality risk was greatest in the collapsed region of the building (adjusted OR 176.7, 95% confidence interval [CI] 65.9-474.2). Age > or =40 was also associated with a significantly increased risk of fatality (OR 3.7, 95% CI 1.4-9.8). Among people found in the noncollapsed region of the building, employees' status compared to a visitor's or child's status was protective (OR 0.13, 95% CI 0.01-1.3). CONCLUSIONS: Structural collapse is the most important risk factor for fatality in a building bombing. Progressive collapse may be prevented through more supportive building design. Protection of vulnerable building occupants can be improved by placement of relevant facilities in more structurally reinforced areas. Regular evacuation training of personnel and clear egress routes may also reduce fatality in a building bombing.
