Background
South Africa is making tremendous progress in the fight against HIV, however, adolescent girls and young women aged 15–24 years (AGYW) remain at higher risk of new HIV infections. This paper investigates socio-demographic and behavioural determinants of HIV infection among AGYW in South Africa.
Methods
A secondary data analysis was undertaken based on the 2012 population-based nationally representative multi-stage stratified cluster random household sample. Multivariate stepwise backward and forward regression modelling was used to determine factors independently associated with HIV prevalence.
Results
Out of 3092 interviewed and tested AGYW 11.4% were HIV positive. Overall HIV prevalence was significantly higher among young women (17.4%) compared to adolescent girls (5.6%). In the AGYW model increased risk of HIV infection was associated with being young women aged 20–24 years (OR = 2.30,
p
= 0.006), and condom use at last sex (OR = 1.91,
p
= 0.010), and decreased likelihood was associated with other race groups (OR = 0.06,
p
< 0.001), sexual partner within 5 years of age (OR = 0.53,
p
= 0.012), tertiary level education (OR = 0.11,
p
= 0.002), low risk alcohol use (OR = 0.19,
p
= 0.022) and having one sexual partner (OR = 0.43,
p
= 0.028). In the adolescent girls model decreased risk of HIV infection was associated with other race groups (OR = 0.01,
p
< 0.001), being married (OR = 0.07),
p
= 0.016], and living in less poor household (OR = 0.08,
p
= 0.002). In the young women’s models increased risk of HIV infection was associated with condom use at last sex (OR = 2.09,
p
= 0.013), and decreased likelihood was associated with other race groups (OR = 0.17,
p
< 0.001), one sexual partner (OR = 0.6,
p
= 0.014), low risk alcohol use (OR = 0.17,
p
< 0.001), having a sexual partner within 5 years of age (OR = 0.29,
p
= 0.022), and having tertiary education (OR = 0.29,
p
= 0.022).
Conclusion
These findings support the need to design combination prevention interventions which simultaneously address socio-economic drivers of the HIV epidemic, promote education, equity and access to schooling, and target age-disparate partnerships, inconsistent condom use and risky alcohol consumption.

IntroductionWhile improvements have been made across the HIV care continuum in South Africa, gaps remain. Relationship-focused couples-based approaches may be one avenue to improve HIV-related outcomes for men and women. Prior couples-based studies have been found to improve several HIV care and treatment outcomes in this context, but few have considered viral suppression as the primary outcome. We aimed to compare a couples-based motivational-interviewing intervention delivered to couples to similar content delivered to men and women in couples separately. We will test the efficacy of this approach in a randomised controlled trial.Methods and analysisOur goal is to enrol 270 heterosexual couples for this trial, with at least one partner living with HIV. Couples will be randomised into one of two arms, stratified by couples’ HIV status. The intervention arm, Simunye (‘We are one’ in isiZulu), will provide two sessions of motivational information and skills regarding HIV-related behaviours to couples together, along with relationship-focused content and skills. The content is based on Partner Steps (P-steps), a couples-focused adaptation of Life Steps, an evidence-based programme shown to improve adherence and viral suppression. The control group will receive two sessions as individuals, with similar HIV-related information but without relationship-focused content. Participants will be followed up at 6, 12 and 18 months postrandomisation. The baseline questionnaire will include measures of relationship domains such as satisfaction and communication, and measures pertaining to HIV and reproductive health (eg, fertility intentions, HIV knowledge and risk perception, and sexual behaviour), and mental health (eg, depression symptoms). The primary outcome is viral suppression, based on dried blood spots. Secondary outcomes will include other aspects of treatment engagement. We will also examine hypothesised mediators of intervention participation, for example, relationship dynamics. Primary analyses will use a multilevel modelling approach, which will feature planned time-averaged comparisons of postbaseline measurements across the intervention and control groups to test the primary hypothesis. The analysis will account for the dyadic nature of the data, for example, participants nested within couples.Ethics and disseminationThis trial was approved by the Institutional Review Board (IRB) at the Human Sciences Research Council in South Africa, protocol number 2/27/01/21, and the IRB at the University of Michigan (HUM 00203672). Human subjects’ concerns or adverse events will be reported to both IRBs and the Data Safety and Monitoring Board. We will disseminate findings to community members and stakeholders via community meetings, as well as by conference presentations and publications in peer-reviewed journals.Trial registration numberClinicaltrials.gov Protocol Registration NCT05231707 registered on 8 February 2022.

Background
The global increase in the utilization of non - prescribed antibiotics (NPA), is concerning, with high persistence within the low and middle-income countries (LMICs). With a negative impact on the health of individuals and communities the use of NPA paves the way to the propagation of superbugs that potentially predisposes to changes in bacterial resistance patterns, antibiotic resistance (AR) and antimicrobial resistance (AMR). This study aimed at estimating through a systematic review and meta-analysis, the prevalence of NPA utilisation and describe its primary sources in LMICs.
Methods
The study is a systematic review and meta-analysis which study protocol was registered in PROSPERO (CRD42017072954). The review used The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The studies searched in databases were deemed eligible if reported evidence of practices of self-medication with antibiotics (SMA) and the prevalence of NPA utilisation within adult participants from LMICs, published between 2007 to 2017. The pooled analyses were carried out using Meta XL statistical software. The pooled prevalence was calculated with a 95% confidence interval (CI). The risk of bias of the included studies was assessed using the Quality in Prognosis Studies (QUIPS) tool.
Results
The review included a total of 11 cross-sectional studies, involving 5080 participants and conducted in LMICs from Asia (India, Laos, Nepal, Pakistan, Sri Lanka and Yemen), Latin America (Guatemala), Africa (Nigeria). All studies reported existing practices of SMA, with reported prevalence ranging from 50% to 93,8%. The pooled prevalence of SMA was 78% (95% CI: 65–89%). The main sources of NPA were; pharmacies, family and friends, old prescriptions, home cabinet and leftover antibiotics.
Conclusion
This study revealed a high prevalence of utilisation of NPA in the studied LMICs, these were found to be twice as high in women than men and those participants aged between 18 and 40 years old. The review suggests f considering broader qualitative and comprehensive contextuallized research to better understand the nuances of NPA use. These would be benefitial to uncover uncover gray areas, inform decisions, support the (re) design and implementation of multifaceted interventions towards antibiotic stewardship and conservancy in LMICs.

Prescription drug diversion, and misuse has increased over the past decade and is notably in high-income-countries and significantly contributes to the opioid epidemic. People living with HIV (PLWH) are particularly vulnerable to prescription drug diversion, and misuse as most experience chronic pain, mental health problems and HIV-related illnesses. The researchers investigated the prevalence and correlates of prescription drug diversion, and misuse among PLWH in the eThekwini district, KwaZulu-Natal.
A cross-sectional study was conducted among 392 PLWH, conveniently recruited from the public healthcare facilities located in rural, semi-urban and urban areas of the eThekwini district. Participants answered questions about their background, prescription medications, substance use, and prescription drug diversion, and misuse. Descriptive analysis was performed to estimate the prevalence of prescription drug diversion, and misuse. Multivariable logistic regression was used to identify predictors of prescription drug diversion, and misuse.
Overall, 13% of the participants reported lifetime prescription drug diversion. The most common type of diversion was using prescription medication not prescribed by a healthcare provider (11%), followed by sharing of prescription medication (9%) and buying prescription medication without a medical script (5%). Twenty-three per cent of the participants reported prescription drug misuse in the past 90 days, with using prescription medication without a healthcare providers' guidance (9%) and not following the scheduled time periods (8%) being the most common reported types of misuse. Self-medicating was identified as a risk factor for prescription drug misuse. There was no association between ART adherence and prescription drug diversion, and misuse.
The study findings contribute to improving the limited data available on prescription drug diversion, and misuse among PLWH in South Africa. The prevalence underscores a need for urgent interventions when prescribing medications with potential risks. Addressing the risk of self-medicating is imperative for HIV care outcomes and to avert death.

Alcohol Drinking - prevention & control
2026
Background
Dyadic monitoring tools could enhance partner awareness of drinking behaviors and prompt timely communication and supportive responses during alcohol use. We posited that real-time blood alcohol content (BAC) levels combined with motivational interviewing (MI) could facilitate couple communication, communal coping, and support, enabling couples to set joint goals and reduce alcohol consumption. We qualitatively explored the positive and negative experiences of trial participants who received mobile breathalyzer technology with couples MI to reduce unhealthy alcohol use in South Africa.
Methods
Thirty couples (60 individuals) participated in a pilot trial combining couples-based MI with mobile breathalyzers. Index participants reporting unhealthy alcohol use and on antiretroviral therapy were assigned a portable breathalyzer linked to a smartphone app to complete twice-daily BAC tests. Partners received real-time SMS notifications of these BAC results. Both partners engaged in three MI sessions to reflect on drinking patterns and set alcohol reduction goals together. Transcripts from audio-recorded sessions and exit interviews from a subset of 12 individuals were analyzed using framework analysis. The data were coded for positive and negative experiences of using the breathalyzers and dyadic mechanisms of behavior change.
Results
Participants averaged 35.9 years old and had relationships averaging 6.6 years. Most couples (66.7%) had two partners reporting unhealthy drinking. Couples found the mobile breathalyzer technology engaging and enjoyable due to its novelty and social curiosity it sparked. Despite challenges related to connectivity issues, privacy, and technical difficulties, participants generally found workarounds and leveraged study resources like power banks and dedicated navigators. Participants described how the breathalyzers enhanced self-awareness of alcohol consumption, promoted home-based drinking, and fostered partner support and communication, though it sometimes led to tensions over technology allocation and usage, when only one partner received the device.
Conclusions
Couples in a low-resource setting in South Africa successfully used breathalyzers to self-monitor alcohol consumption. Breathalyzers could be used to increase personal motivation to reduce alcohol use, activate partner support, and help partners coordinate efforts to achieve drinking goals. Addressing structural challenges like cellular connectivity, as well as dyadic equity by providing both partners with breathalyzers, will be critical to maximizing breathalyzer uptake and intervention impact in resource-poor settings.

Melasma in people with darker skin types: a scoping review protocol on prevalence, treatment options for melasma and impact on quality of life
2023
Background
Melasma is one of the most encountered dermatoses in dermatology and skin care clinics. It is a challenging chronic, recurrent condition associated with hyperpigmentation. Its aetiology is poorly understood. Melasma affects all races and gender but is more prevalent in women with darker skin types. Being a facial lesion, melasma has a severe impact on quality of life due to its disfigurement. While many modalities of treatment for melasma exists, unfortunately, effectiveness and safety remain a huge concern. Treatment modalities are variable and often unsatisfactory. The objective of this scoping review is to systemically map available evidence from literature regarding melasma on people with darker skin types, garner insight as to how melasma affects the quality of life and begin to investigate and gain understanding on effectiveness of different treatments used for melasma.
Methods
A scoping review guided by Arksey and O’Malley’s framework, the enhancements and recommendations of Levac, Colquhoun and O’Brien, Daudt and associates and the 2015 Johanna Briggs Institute’s guidelines will be conducted. Systematic electronic searches of databases and search engines will include Scopus, PubMed, CINAHL Complete, Cochrane, Science Direct, and Web of Science which will be conducted to attain published peer-reviewed articles of all study designs excluding reviews and grey literature. All literature that meets the inclusion criteria, research question and sub-question will be included in this review. All the retrieved literature will be exported to an Endnote X20 library. Quality appraisal of the included articles will be conducted using the mixed methods appraisal tool (MMAT) 2018 version.
Discussion
We anticipate mapping relevant literature on the melasma, investigating the effectiveness of treatment options of melasma as well as evaluating its association with quality of life in people with darker skin types. This study is likely to reveal research gaps, which could guide future implementation research on melasma treatment interventions.

IntroductionHeavy alcohol use among people living with HIV in sub-Saharan Africa can hinder the success of HIV treatment programmes, impacting progress towards United Nations Programme on HIV/AIDS goals. Primary partners can provide critical forms of social support to reduce heavy drinking and could be included in motivational interviewing (MI) interventions to address heavy drinking; however, few studies have evaluated MI interventions for couples living with HIV in sub-Saharan Africa. We aim to evaluate the feasibility and acceptability of a couple-based MI intervention with mobile breathalyser technology to reduce heavy alcohol use and improve HIV treatment outcomes among HIV-affected couples in South Africa.Methods and analysisWe will employ a three-arm randomised controlled trial to assess the efficacy of couple-based MI (MI-only arm) and in conjunction with mobile breathalysers (MI-plus arm) to address alcohol use and HIV outcomes, as compared with enhanced usual care (control arm). We will enrol heterosexual couples aged 18–49 in a primary relationship for at least 6 months who have at least one partner reporting hazardous alcohol use and on antiretroviral therapy for 6 months. Participants in both MI arms will attend three manualised counselling sessions and those in the MI-plus arm will receive real-time feedback on blood alcohol concentration levels using a mobile breathalyser. Couples randomised in the control arm will receive enhanced usual care based on the South African ART Clinical Guidelines. Feasibility and acceptability indicators will be analysed descriptively, and exploratory hypotheses will be examined through regression models considering time points and treatment arms.Ethics and disseminationThe study was approved by the University of California, San Francisco (HRPP; protocol number 21-35034) and Human Sciences Research Council Research Ethics Committee (REC: protocol number 1/27/20/21). We will disseminate the results at local community meetings, community-level health gatherings and conferences focused on HIV and alcohol use.Trial registration numberNCT05756790.

Background In South Africa, age-disparate to sexual relationships where the age difference between partners is 5 years or greater is an important contributor to the spread of HIV. However, little is known about the predictors of age-disparate sexual relationships. This study investigates factors associated with age-disparate sexual relationships among males and females in South Africa. Methods This analysis used the 2012 nationally representative population-based household survey conducted using multi-stage stratified cluster sampling design. Multivariate multinomial stepwise logistic regression models were used to determine factors associated with age-disparate sexual relationships. Results Of 15,717 participants, who responded to the question on age-disparate sexual relationships, 62% males versus 58.5% females had partners within 5 years older or younger, 34.7% of males versus 2.7% of females had partners at least 5 years younger and 3.3% of males versus 38.8% of females had partners at least 5 years older. Among both males and females predictors of age-disparate sexual relationships were education, employment, socioeconomic status, locality type, age at sexual debut, condom use at last sexual act and HIV status while race was also an additional predictor for among females. Including unprotected sex and risk of HIV infection among adolescent girls and young women with sexual partners 5 years older their age. Conclusions This study suggest that there is a need for reprioritizing the combination of behavioural and structural interventions to address risky sexual behaviours, unprotected sex, poverty, limited education and gender inequitable norms related to age-disparate sexual relationships and HIV.

Melasma is a challenging chronic skin condition associated with hyperpigmentation and unknown aetiology. This scoping review maps evidence of available treatments and their effectiveness in darker skin types. A comprehensive, systematic online search was conducted in Scopus, PubMed, CINAHL Complete, Cochrane, ScienceDirect, and Web of Science Core Collection. All eligible titles were exported to an EndNote20 library (Clarivate analytics, US). Thematic content analysis was performed to summarise data on current melasma treatments for darker skin types. The quality of included articles was appraised using the Mixed Methods Appraisal Tool (MMAT) 2018 version. A total of 2863 articles were retrieved from the databases, and 10 met the eligibility criteria following abstract and full-text screening. Our findings demonstrate that topical treatments, chemical peels, lasers, and tranexamic acid are common treatment modalities used in darker skin types. Although these treatments may be effective in the short term, they bring about undesirable side effects and sometimes worsen or result in reoccurrences of melasma. Based on the evidence mapped, current treatment modalities are not suitable for darker skin types. There are very few studies conducted on individuals of African descent. Further research is necessary to investigate treatment interventions that may be user-friendly when dealing with darker skin types.

Background
Prescription drugs are controlled medicines due to their potential risks of being diverted, misused, and abused. Since the introduction of antiretroviral (ARVs) drugs, HIV is currently regarded as a chronic condition. However, prescription drug diversion, misuse, and abuse might serve as one of the critical barriers for achieving optimal medication adherence among people living with HIV, thereby negatively impacting the HIV care mandate. The primary aim of this scoping review is to gather evidence on the prevalence, practices, risk factors, and motives associated with prescription drug diversion, misuse, and abuse, as well as the evidence on the association between prescription drug diversion, misuse, and abuse with antiretroviral treatment (ART) adherence.
Methods
This review will be guided by Arksey and O’Malley’s framework as well as recommendations by Levac et al. (Implement Sci 5:69, 2010). We will search the following databases for relevant literature meeting our eligibility criteria: PubMed, Google Scholar, EBSCOhost (Academic Search Complete, MEDLINE, and Newspaper Source), World Health Organization, Science Direct, and Open Access Theses and Dissertations. Studies published within the period of January 1996 to June 2019 are eligible. The included studies should report evidence on the prevalence, practices, risk factors, motives, or association between ART adherence and prescription drug diversion, misuse, and abuse. Thematic analysis will be applied to summarize the review findings.
Discussion
We anticipate finding a considerable number of research studies on prescription drug diversion, misuse, and abuse among people living with HIV. Our synthesis of this evidence base is intended to serve as guidance for future research studies. The study findings will be disseminated through the traditional academic platforms, such as peer-reviewed publications and presentations at relevant local and international conferences, symposiums, and seminars.
