Most studies on HIV testing among young people in Nigeria are not nationally representative. As such, recent representative data, such as the Multiple Indicator Cluster Survey (MICS), could help assess current level of people, a key target population for prevention country. In this study, we examined coverage and factors associated with adolescents adults (AYA).We used data 14,312 AYA that lifetime from 2017 MCIS. Our outcomes interest were ever tested recently HIV. We association between...
Peer-to-peer (PTP) HIV self-testing (HIVST) distribution models can increase uptake of testing and potentially create demand for treatment pre-exposure prophylaxis (PrEP). We describe the acceptability experiences young women men participating in a cluster randomised trial PTP HIVST antiretroviral/PrEP promotion rural KwaZulu-Natal. Between March September 2019, 24 pairs trained peer navigators were to two approaches distribute packs (kits+HIV prevention information):...
The use of mobile communication technologies (mHealth: health) in chronic disease management has grown significantly over the years. mHealth interventions have potential to decentralize access health care and make it convenient, particularly resource-constrained settings. It is against this backdrop that we aimed codevelop (with users) a new generation phone-connected HIV diagnostic tests Web-based clinical pathways needed for optimal delivery decentralized testing, prevention, low-...
BackgroundEmpagliflozin has been proposed as a treatment for COVID-19 on the basis of its anti-inflammatory, metabolic, and haemodynamic effects. The RECOVERY trial aimed to assess safety efficacy in patients admitted hospital with COVID-19.MethodsIn randomised, controlled, open-label trial, several possible treatments are compared usual care hospitalised COVID-19. In this analysis, we eligible consenting adults who were randomly allocated 1:1 ratio either standard alone or plus oral...
Abstract Background Despite effective biomedical tools, HIV remains the largest cause of morbidity/mortality in South Africa – especially among adolescents and young people. We used community-based participatory research (CBPR), informed by principles social justice, to develop a peer-led biosocial intervention for prevention KwaZulu-Natal (KZN). Methods Between March 2018 September 2019 we CBPR iteratively co-create contextually adap t support prevention. Men women aged 18–30 years were...
Background. The South African (SA) government introduced Implanon NXT, a long-acting subdermal contraceptive implant, in 2014 to expand choice. Following an initial high uptake, its use declined considerably amid reports of early removals and frequent side-effects. We examine providers’ perceptions training attitudes towards as well their views on the causes impact implant service. Objective. To assess healthcare services SA. Methods. In-depth interviews were conducted with eight nurses...
Background. Implanon NXT, a long-acting reversible contraceptive, was introduced in South Africa (SA) early 2014, aiming to expand the method mix and increase its effectiveness. Initial uptake high, but has since declined considerably. In these years after implant’s introduction, it is important identify reasons for decline, remedy gaps services. Objectives. To determine periods of use, use removal implant NXT. Methods. 2016, we recruited 152 women from six clinics City Johannesburg, North...
We investigated two peer distribution models of HIV self-testing (HIVST) in prevention demand creation compared with trained young community members (peer navigators).
Abstract Introduction The uptake of HIV testing and linkage to care remains low among men, contributing high incidence in women South Africa. We conducted the “Home‐Based Intervention Test Start” (HITS) a 2x2 factorial cluster randomized controlled trial one World’s largest ongoing cohorts rural Africa aimed at enhancing both intrinsic extrinsic motivations for testing. Methods Between February December 2018, uMkhanyakude district KwaZulu‐Natal, we randomly assigned 45 communities (clusters)...
The 2015 El Niño-triggered drought in Southern Africa caused widespread economic and livelihood disruption South Africa, imposing multiple physical health challenges for rural populations including people living with HIV (PLHIV). We examined the economic, social demographic impacts of drawing on 27 in-depth interviews two cohorts PLHIV Hlabisa, uMkhanyakude district, KwaZulu-Natal. Thematic analysis revealed how drought-enforced soil water depletion, dried-up rivers, dams culminated a...
People living in rural areas generally experience adverse health outcomes compared to their urban counterparts. They a greater burden of non-communicable diseases including: diabetes, hypertension, stroke, kidney disease, and chronic obstructive pulmonary disease (COPD), have limited access healthcare services, scarcity specialized services. The disproportionately high all-cause mortality experienced by residents has been termed "the penalty". With over 90% the world's population Africa...
Abstract Introduction HIV elimination requires innovative approaches to ensure testing and immediate treatment provision. We investigated the effectiveness of conditional financial incentives on increasing linkage care in a 2×2 factorial cluster randomized controlled trial-Home-Based Intervention Test Start (HITS) - rural South Africa. Methods Of 45 communities uMkhanyakude, KwaZulu-Natal, 16 were randomly assigned arms receive for home-based counseling (HBHCT) within 6 weeks (R50 [US$3]...
With over 200 million people, 50% of Nigeria's population comprises women reproductive age (15-49 years), making Sexual Reproductive Health and Rights (SRHR) invaluable in achieving SDGs 3 5 on health well-being gender equality, respectively. Although indices have improved the past two decades, some critical gaps must be closed. We examined SRHR trends Nigeria using Nigerian DHS data sets spanning 2003-2018. Key indicators included contraceptive prevalence, skilled assistance during...
This study examined the impact of different ultrasonication (USN) times on faba bean starch (FBS). Starch samples were ultrasonicated using an ultrasonic bath for 0, 5, 15, 30, 50, and 60 min. The composition, morphology, structure, pasting properties starches analyzed. Both native modified exhibited high lightness values (93.93-96.02) variable amylose contents (31.59-31.75%). content increased with USN time up to 30 min before declining. did not alter crystallinity pattern (CB-type). Still,...

Abstract Background Post sexual-based violence (SBV) services are crucial for mitigating SBV-induced consequences. However, these reportedly rare and often underutilized, particularly by young women in Sub-Saharan Africa. This study aimed to explore the barriers facilitators accessing post-SBV among (18–24 years) attending higher education institutions Nigeria. Methods An online survey, using a piloted questionnaire, was administered purposive sample of 114 participants recruited from social...
