RESUMO

BACKGROUND: Food and water insecurity are associated with poor health outcomes that may be exacerbated by social marginalization and barriers to health care experienced by sexual and gender minorities (SGM) in resource-limited settings. We explored factors associated with food and water insecurity in SGM with HIV. SETTING: A longitudinal study of 357 men who have sex with men, transgender women, and other gender-identifying people in Lagos, Nigeria. METHODS: Laboratory testing, interviews, food and water assessments, and anthropometry were performed quarterly. Robust Poisson regression with generalized estimating equations was used to evaluate factors potentially associated with food and water insecurity. RESULTS: From 2014 to 2018, 357 SGM with HIV completed either the food or water assessments. At baseline, participants identified as cisgender men who have sex with men 265 (74.2%), transgender women 63 (17.7%), or as nonbinary/other gender 29 (8.1%). Food insecurity and water insecurity were reported by 63/344(18.3%) and 113/357(31.7%), respectively, at any visit. Food and water insecurity each decreased with ongoing study participation. Food insecurity was associated with nonpartnered relationship status, CD4 count <500 cells/mm 3 , and lack of access to piped water. Water insecurity was associated with age 25 years or older, living with a man, transactional sex, and food insecurity. CONCLUSIONS: Food and water insecurity were common among SGM in Nigeria and decreased with continued study participation, suggesting amenability to intervention when SGM are successfully engaged in care. Targeted interventions to support food and water security may improve HIV-related outcomes, such as CD4 count.

RESUMO

Recent outbreaks of viral hemorrhagic fevers (VHFs), including Ebola virus disease (EVD) and Lassa fever (LF), highlight the urgent need for sensitive, deployable tests to diagnose these devastating human diseases. Here we develop CRISPR-Cas13a-based (SHERLOCK) diagnostics targeting Ebola virus (EBOV) and Lassa virus (LASV), with both fluorescent and lateral flow readouts. We demonstrate on laboratory and clinical samples the sensitivity of these assays and the capacity of the SHERLOCK platform to handle virus-specific diagnostic challenges. We perform safety testing to demonstrate the efficacy of our HUDSON protocol in heat-inactivating VHF viruses before SHERLOCK testing, eliminating the need for an extraction. We develop a user-friendly protocol and mobile application (HandLens) to report results, facilitating SHERLOCK's use in endemic regions. Finally, we successfully deploy our tests in Sierra Leone and Nigeria in response to recent outbreaks.

RESUMO

BACKGROUND: Men who have sex with men (MSM) and transgender women (TGW) are disproportionately impacted by HIV and may face barriers to HIV status disclosure with negative ramifications for HIV prevention and care. We evaluated HIV status disclosure to sexual partners, HIV treatment outcomes, and stigma patterns of MSM and TGW in Abuja and Lagos, Nigeria. METHODS: Previously-diagnosed MSM and TGW living with HIV who enrolled in the TRUST/RV368 cohort from March 2013 to August 2018 were asked, "Have you told your (male/female) sexual partners (MSP/FSP) that you are living with HIV?" In separate analyses, robust Poisson regression models were used to estimate risk ratios (RRs) and 95% confidence intervals (95% CIs) for characteristics associated with HIV status disclosure to MSP and FSP. Self-reported stigma indicators were compared between groups. RESULTS: Of 493 participants living with HIV, 153 (31.0%) had disclosed their HIV status to some or all MSP since being diagnosed. Among 222 with FSP, 34 (15.3%) had disclosed to some or all FSP. Factors independently associated with disclosure to MSP included living in Lagos (RR 1.58 [95% CI 1.14-2.20]) and having viral load < 50 copies/mL (RR 1.67 [95% CI 1.24-2.25]). Disclosure to FSP was more common among participants who were working in entertainment industries (RR 6.25 [95% CI 1.06-36.84]) or as drivers/laborers (RR 6.66 [95% CI 1.10-40.36], as compared to unemployed) and also among those married/cohabiting (RR 3.95 [95% CI 1.97-7.91], as compared to single) and prescribed ART (RR 2.27 [95% CI 1.07-4.83]). No differences in self-reported stigma indicators were observed by disclosure status to MSP but disclosure to FSP was associated with a lower likelihood of ever having been assaulted (26.5% versus 45.2%, p = 0.042). CONCLUSIONS: HIV status disclosure to sexual partners was uncommon among Nigerian MSM and TGW living with HIV but was associated with improved HIV care outcomes. Disclosure was not associated with substantially increased experiences of stigma. Strategies to encourage HIV status disclosure may improve HIV management outcomes in these highly-marginalized populations with a high burden of HIV infection.

RESUMO

INTRODUCTION: Snakebite envenoming is a major cause of morbidity and mortality in rural areas of the tropics. Timely administration of effective antivenom remains the mainstay of management. METHODS: The study was a quantitative descriptive study aimed at exploring the causes and effects of delay, distance and time taken to access care on snakebite outcomes in Nigeria. All prospective snakebite victims reporting to Kaltungo General Hospital were enrolled. Data on demography, date and time bitten, date and time admitted, site of bite, circumstances of snakebite, responsible snake, clinical features, 20-minute whole-blood clotting test, antivenom administered and outcome were recorded. Delay arising from use of traditional first aid (TFA), time elapsed from snakebite to presentation and the shortest distance from bite location to the hospital was calculated or obtained using a global positioning system. RESULTS: The association between delay before hospital presentation and poor outcome was not statistically significant, even though there was a 2% higher likelihood of poor outcome among those with a 1-hour delay compared to those without delay (odds ratio 1.02, 95% confidence interval 1.00-1.03). There was no difference in distance from bite location to hospital between those with a poor outcome (74) compared to those with a good outcome (325). Those with a poor outcome had more severe envenomation requiring more antivenoms and longer hospital stays. Given poor access to antivenom therapy at distant locations ≥100 km, victims were more likely to use TFA such as black 'snake' stone, with consequent prolonged delays. Antivenoms should be more readily available at distant places. CONCLUSIONS: Community education on avoiding potentially harmful TFA and prompt access to care is recommended. There is a need to provide snakebite care to multiple peripheral, relatively more rural inaccessible areas.
