Sexual behaviours and risk with women in MSM in sub-Saharan Africa

In sub-Saharan Africa (SSA), MSM - a high HIV prevalence group - experience strong social stigma and pressure to have female partners. Accordingly, they could constitute a bridging group for HIV transmission to cisgender women. We developed a multilevel summary of MSM sexual behaviors and risk with women in various SSA regions. Following PRISMA guidelines, we conducted a mixed-method systematic review of data of sex with women in MSM in SSA. We performed meta-analyses on quantitative data (i.e. percent of recent sex and condomless sex with women) for each SSA region (when proportions reported in ≥4 studies). Pooled proportions were calculated using random-effects models. Qualitative data were analyzed using the three-step thematic synthesis methodology. The pooled proportion of MSM who had sex with women was 58% (33-83%) in East Africa (in the previous 3 months), and 27% (13-48%) in Southern Africa and 50% (95% CI 39-62%) in West Africa (in the previous 6 months); 23% (16-32%) of MSM in West Africa had condomless sex with a woman (during the most recent encounter). Approximately one quarter of MSM had recent multiple female partners. MSM reported having sex with women because of heteronormative pressure, erotic/romantic attraction, or financial needs leading to transactional sex. MSM may act as a bridging population to women in SSA, as they commonly practice sex with women and risky sexual behaviors with them. HIV programmes and community-based support for MSM should be adapted to this population to reduce this risk.

Diversity of Glossinidae (Diptera) species in The Gambia in relation to vegetation

Glossina species are known to transmit African Trypanosomiasis, one of the most important infectious diseases for both livestock and humans in sub-Saharan Africa. Therefore, the aim of this study was to characterize trapped Glossina spp. from The Gambia using morphological and molecular techniques in relation to the vegetation cover types. A line transect survey was carried out in all the administrative regions of The Gambia. Tsetse fly trapping was carried out for 14 days during each season using line transect. A total of 220 Glossina spp. specimens (117 F and 103 M) were captured, and DNA was extracted from the legs of 100 randomly selected Glossina spp. Further, DNA samples were tested by a conventional PCR assay. A total of 135/220 (61%; 95% CI: 54.6-67.8%) and 85/220 (39%; 95% CI: 32.2-45.4%) flies were identified as Glossina morsitans submorsitans and Glossina palpalis gambiensis, respectively, with most caught during wet season (53.6%) and more females (53.2%) than males. Results of the morphological identification agreed with those of molecular identification. The type of vegetation cover significantly influenced the caught of tsetse flies. Animals and humans at the various trapping sites are at risk of being bitten by tsetse flies.

Closing the diagnostic gap: Liquid biopsy potential to transform ovarian cancer outcomes in sub-Saharan Africa

Ovarian cancer presents a significant health challenge in sub-Saharan Africa (SSA), where late-stage diagnosis contributes to high mortality rates. This diagnostic gap arises from limited resources, poor healthcare infrastructure, and a lack of awareness about the disease. However, a potential game-changer is emerging in the form of liquid biopsy (LB), a minimally invasive diagnostic method. This paper analyses the current diagnostic gap in ovarian cancer in SSA, highlighting the socio-economic, cultural, and infrastructural factors that hinder early diagnosis and treatment. It discusses the challenges and potential of LB in the context of SSA, emphasizing its cost-effectiveness and adaptability to resource-limited settings. The transformative potential of LB in SSA is promising, offering a safer, more accessible, and cost-effective approach to ovarian cancer diagnosis. This paper provides recommendations for future directions, emphasizing the need for research, infrastructure development, stakeholder engagement, and international collaboration. By recognizing the transformative potential of LB and addressing the diagnostic gap, we can pave the way for early detection, improved treatment, and better outcomes for ovarian cancer patients in SSA. This paper sheds light on a path toward better healthcare access and equity in the region.

Survey of Teleneurology Use by Neurologists in a Low-Middle Income Country

Background Teleneurology has been in existence for decades, and the COVID-19 pandemic has escalated its widespread usage. Neurological conditions are a leading cause of death globally, with sub-Saharan Africa bearing the bulk of the burden. Nigeria has few trained neurologists with the few available concentrated in an urban region. The adoption of teleneurology will help close this treatment gap. Despite evidence of its advantage, the adoption and state of teleneurology in Nigeria are very low. This study aims to determine the state and perception of teleneurology in the care of neurological patients in Nigeria and identify challenges to its wide usage. Methods The primary research method was a descriptive cross-sectional survey among 48 neurologists in Nigeria across the six geo-political zones of the country. Descriptive statistics such as frequency and percentage were used to summarize and present the results. Results A total of 48 neurologists participated, of which 46 (95.8%) specialized in general neurology. Videoconferencing is the most preferred means of telemedicine (24, 50%), followed by phone calls (16, 33.3%) and short messages (6, 12.5%). Three-quarters of the respondents are concerned about legal actions from telemedicine use. The majority (34, 70.9%) are not familiar with telemedicine tools, and 40 (83.3%) indicate low telemedicine seminar attendance. More than 90% (46) of neurologists believe that it is a viable approach and can save time and money. Barriers to telemedicine included the lack of incentive to use the technology (38, 79.2%), poor Internet connectivity (36, 75%), and the lack of exposure to telemedicine (36, 75%). Conclusions It is important to overcome the existing barrier to teleneurology in order to fully harness its potential in addressing the shortage of health professionals in Nigeria as most neurologists are open to using it.

The Rwandan Healthcare System: Can a Shifting Burden of Disease Threaten a Post-war Success Story?

Rwanda is located in Central Africa, bordered by the Democratic Republic of Congo (DRC), Burundi, Tanzania, and Uganda. In 1994, Rwanda was immersed in a brutal war and genocide. Rwanda's subsequent remarkable post-war recovery has been well documented. What this paper aims to do is to explore Rwanda's successes and the vulnerability it faces with the shifting burdens of diseases. This paper seeks to contribute to the global discourse on effective healthcare models in resource-limited, post-conflict settings, even as such countries achieve improved socio-economic conditions and experience associated changes in population disease patterns.

Factors associated with insulin resistance in a longitudinal study of Ugandan youth with and without HIV

Prospective investigations from sub-Saharan Africa on metabolic complications in youth with perinatally acquired HIV (PHIV) are lacking. We investigated the changes in insulin resistance in Ugandan PHIV on ART and uninfected controls and their relationship with inflammation, HIV, and cardiovascular disease (CVD) risk factors. Participants 10-18 years of age were included in a prospective study performed in Kampala, Uganda. We compared baseline and changes in insulin resistance (by HOMA-IR) and in markers of inflammation at baseline and 96 weeks. PHIVs were on ART with HIV-1 RNA level 400 copies/ml or less. Generalized Estimating Equation models were used to assess associations between HOMA-IR, and demographic as well as inflammatory markers. Of the 197 participants recruited at baseline (101 PHIV, 96 HIV-negative), 168 (89 PHIV, 79 HIV-negative) had measurements at 96 weeks. At baseline, median (Q1, Q3) age was 13 years (11,15), 53.5% were women, median CD4 + cell counts were 988 cells/μl (631, 1310). At baseline, HOMA-IR was significantly higher in PHIV than in controls ( P  = 0.03). HOMA-IR did not significantly change by week 96 in either group, and at 96 weeks, was similar between groups ( P  = 0.15). HOMA-IR was not associated with any inflammatory markers, or any specific ART. In longitudinal analysis, age and Tanner stage remained associated with higher HOMA-IR throughout the study period, after adjusting for HIV status. In this longitudinal cohort of virally suppressed PHIV in Uganda, PHIV have decreased insulin sensitivity compared to controls, however this difference does not persist through adolescence. ART and immune activation do not appear to affect glucose homeostasis in this population.

Differences in Breastfeeding Duration by Maternal HIV Status: A Pooled Analysis of Nationally Representative Surveys in Sub-Saharan Africa

BACKGROUND

Breastfeeding improves child survival but is a source of mother-to-child HIV transmission among women with unsuppressed HIV infection. Estimated HIV incidence in children is sensitive to breastfeeding duration among mothers living with HIV (MLHIV). Breastfeeding duration may vary according to maternal HIV status.

SETTING

Sub-Saharan Africa.

METHODS

We analyzed pooled data from nationally representative household surveys conducted during 2003-2019 that included HIV testing and elicited breastfeeding practices. We fitted survival models of breastfeeding duration by country, year, and maternal HIV status for 4 sub-Saharan African regions (Eastern, Central, Southern, and Western).

RESULTS

Data were obtained from 65 surveys in 31 countries. In 2010, breastfeeding in the first month of life ("initial breastfeeding") among MLHIV ranged from 69.1% (95% credible interval: 68-79.9) in Southern Africa to 93.4% (92.7-98.0) in Western Africa. Median breastfeeding duration among MLHIV was the shortest in Southern Africa at 15.6 (14.2-16.3) months and the longest in Eastern Africa at 22.0 (21.7-22.5) months. By comparison, HIV-negative mothers were more likely to breastfeed initially (91.0%-98.7% across regions) and for longer duration (median 18.3-24.6 months across regions). Initial breastfeeding and median breastfeeding duration decreased during 2005-2015 in most regions and did not increase in any region regardless of maternal HIV status.

CONCLUSIONS

MLHIV in sub-Saharan Africa are less likely to breastfeed initially and stop breastfeeding sooner than HIV-negative mothers. Since 2020, UNAIDS-supported HIV estimates have accounted for this shorter breastfeeding exposure among HIV-exposed children. MLHIV need support to enable optimal breastfeeding practices and to adhere to antiretroviral therapy for HIV treatment and prevention of postnatal mother-to-child transmission.

"I Have to Do It in Secrecy": Provider Perspectives on HIV Service Delivery and Quality of Care for Key Populations in Zambia

ABSTRACT

Key populations (KPs) experience suboptimal outcomes along the HIV care and prevention continua, but there is limited study of the challenges service providers encounter delivering HIV services to KPs, particularly in settings like Zambia, where provision of these services remains legally ambiguous. Seventy-seven providers completed in-depth interviews exploring constraints to HIV service delivery for KPs and recommendations for improving access and care quality. Thematic analysis identified salient challenges and opportunities to service delivery and quality of care for KPs, spanning interpersonal, institutional, and structural domains. Limited provider training in KP-specific needs was perceived to influence KP disclosure patterns in clinical settings, impeding service quality. The criminalization of KP sexual and drug use behaviors, coupled with perceived institutional and legal ambiguities to providing HIV services to KPs, cultivated unwelcoming service delivery environments for KPs. Findings elucidate opportunities for improving HIV service delivery/quality, from decentralized care to expanded legal protections for KPs and service providers.

Temporal Trends and Determinants of HIV Testing at Antenatal Care in Sub-Saharan Africa: A Pooled Analysis of Population-Based Surveys (2005-2021)

BACKGROUND

In sub-Saharan Africa (SSA), integrating HIV testing into antenatal care (ANC) has been crucial toward reducing mother-to-child transmission of HIV. With the introduction of new testing modalities, we explored temporal trends in HIV testing within and outside of ANC and identified sociodemographic determinants of testing during ANC.

METHODS

We analyzed data from 139 nationally representative household surveys conducted between 2005 and 2021, including more than 2.2 million women aged 15-49 years in 41 SSA countries. We extracted data on women's recent HIV testing history (<24 months), by modality (ie, at ANC versus outside of ANC) and sociodemographic variables (ie, age, socioeconomic status, education level, number of births, urban/rural). We used Bayesian generalized linear mixed models to estimate HIV testing coverage and the proportion of those that tested as part of ANC.

RESULTS

HIV testing coverage (<24 months) increased substantially between 2005 and 2021 from 8% to 38%, with significant variations between countries and subregions. Two percent of women received an HIV test in the 24 months preceding the survey interview as part of ANC in 2005 and 11% in 2021. Among women who received an HIV test in the 24 months preceding the survey, the probability of testing at ANC was significantly greater for multiparous, adolescent girls, rural women, women in the poorest wealth quintile, and women in West and Central Africa.

CONCLUSION

ANC testing remains an important component to achieving high levels of HIV testing coverage and benefits otherwise underserved women, which could prove instrumental to progress toward universal knowledge of HIV status in SSA.

Mobile health follow-up screening to risk stratify patients in need of further care in a low resource setting: Results from a prospective multisite implementation study

BACKGROUND

Routine in-person follow-up for injured patients after hospital discharge is unfeasible in low- and middle-income countries where trauma morbidity and mortality are the highest. Mobile technology screening may facilitate early detection of complications and timely treatment. In this prospective, multisite implementation study, we cross-validate the performance of a cellphone screening tool developed to risk stratify trauma patients in need of further care after discharge in Cameroon.

METHODS

Between June 2019 and August 2022, research assistants contacted trauma patients by cellphone 2 weeks after discharge to administer a 14-question follow-up survey. All surveyed patients were asked to return for a physical examination. Physicians blinded to survey results categorized patients as low or moderate or high risk (HR) for poor outcomes without further care. Logistic regression tested associations between each survey question and physician examination. Predictive survey questions generated a preliminary model with high sensitivity for identifying patients in need of further care.

RESULTS

Of 1,712 successfully contacted patient households, 96% (1643) participated in telephone triage compared with 33% (560) who returned for physician examination. Physicians designated 39% (220) as being HR. On multiple logistic regression, 8 of 13 candidate triage questions were independently associated with HR. Positive survey response on the resultant eight question screen yielded 89.2% sensitivity for HR with a 10.8% false negative rate. Weighted for variable importance based on triage risk scores, 39% of triaged patients screened as low risk, 39% as moderate risk, and 22% as high risk for HR. Likelihood of HR was significantly greater for patients screening as high (odds ratio, 5.9) or moderate risk (odds ratio, 1.9; both p < 0.01).

CONCLUSION

Cellphone triage provides sensitive risk stratification of patients in need of further care after hospital discharge in Cameroon. Given low in-person return rates, limited resources should highly prioritize efforts to repatriate patients screening as high risk for poor outcomes.

Pneumonia in Sudan: Systematic and Scoping Review of the Literature and Meta-Analysis

In addition to excessive burden of non-communicable diseases, natural and manmade disasters, and internal conflicts, Sudan is predominantly susceptible to communicable diseases, such as malaria, tuberculosis, and pneumonia, which bring about an extra burden of demand for high-quality healthcare. According to the WHO and the Sudan Health Observatory, pneumonia is one of the leading causes of death in Sudan. This study therefore aimed to illustrate pneumonia literature in Sudan, estimate infection prevalence regardless of the cause among Sudanese children and adults, and demonstrate its related risk factors. A systematic and scoping review of the literature was conducted and regulated in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). After abstract and full-text screening, only 15 articles met our inclusion criteria and passed the quality assessment procedure. Seven included studies determined prevalence of pneumonia; the overall pooled prevalence was around 30%. Furthermore, 12 research articles investigated risk factors related to pneumonia among Sudanese population. Further research with larger sample sizes targeting risk factors of pneumonia among Sudanese population is needed to be conducted.

Doxycycline vs Hydroxychloroquine + Azithromycin in the Management of COVID-19 Patients: An Open-Label Randomized Clinical Trial in Sub-Saharan Africa (DOXYCOV)

Objective We aimed to compare the safety and efficacy of a doxycycline-based regimen against Cameroon National Standard Guidelines (hydroxychloroquine plus azithromycin) for the treatment of mild symptomatic COVID-19. Methods We conducted an open-label, randomized, non-inferiority trial in Cameroon comparing doxycycline 100 mg, twice daily for seven days versus hydroxychloroquine 400 mg daily for five days and azithromycin 500 mg at day 1 and 250 mg from day 2 through 5 in mild COVID-19 patients. Clinical recovery, biological parameters, and adverse events were assessed. The primary outcome was the proportion of clinical recovery on days 3, 10, and 30. Non-inferiority was determined by the clinical recovery rate between protocols with a 20-percentage points margin. Results One hundred and ninety-four participants underwent randomization and were treated either with doxycycline (n = 97) or hydroxychloroquine-azithromycin (n = 97). On day 3, 74/92 (80.4%) participants on doxycycline versus 77/95 (81.1%) on hydroxychloroquine-azithromycin-based protocols were asymptomatic (p = 0.91). On day 10, 88/92 (95.7%) participants on doxycycline versus 93/95 (97.9%) on hydroxychloroquine-azithromycin were asymptomatic (p = 0.44). On day 30, all participants were asymptomatic. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) polymerase chain reaction (PCR) test was negative on day 10 in 60/92 (65.2%) participants who were assigned to doxycycline and in 63/95 (66.3%) participants who were assigned to hydroxychloroquine-azithromycin. None of the participants were admitted for worsening of the disease after treatment initiation. Conclusion Doxycycline 100 mg twice daily for seven days proved to be safe and non-inferior in terms of efficacy when compared to hydroxychloroquine-azithromycin for preventing clinical worsening of mild symptomatic or asymptomatic COVID-19 and achieving virological suppression.

Universal HIV Testing and Treatment With Patient-Centered Care Improves ART Uptake and Viral Suppression Among Adults Reporting Hazardous Alcohol Use in Uganda and Kenya

OBJECTIVES

Determine whether patient-centered, streamlined HIV care achieves higher antiretroviral therapy (ART) uptake and viral suppression than the standard treatment model for people with HIV (PWH) reporting hazardous alcohol use.

DESIGN

Community cluster-randomized trial.

METHODS

The Sustainable East Africa Research in Community Health trial (NCT01864603) compared an intervention of annual population HIV testing, universal ART, and patient-centered care with a control of baseline population testing with ART by country standard in 32 Kenyan and Ugandan communities. Adults (15 years or older) completed a baseline Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) and were classified as no/nonhazardous (AUDIT-C 0-2 women/0-3 men) or hazardous alcohol use (≥3 women/≥4 men). We compared year 3 ART uptake and viral suppression of PWH reporting hazardous use between intervention and control arms. We compared alcohol use as a predictor of year 3 ART uptake and viral suppression among PWH, by arm.

RESULTS

Of 11,070 PWH with AUDIT-C measured, 1723 (16%) reported any alcohol use and 893 (8%) reported hazardous use. Among PWH reporting hazardous use, the intervention arm had higher ART uptake (96%) and suppression (87%) compared with control (74%, adjusted risk ratio [aRR] = 1.28, 95% CI: 1.19 to 1.38; and 72%, aRR = 1.20, 95% CI: 1.10 to 1.31, respectively). Within arm, hazardous alcohol use predicted lower ART uptake in control (aRR = 0.86, 95% CI: 0.78 to 0.96), but not intervention (aRR = 1.02, 95% CI: 1.00 to 1.04); use was not predictive of suppression in either arm.

CONCLUSIONS

The Sustainable East Africa Research in Community Health intervention improved ART uptake and viral suppression among PWH reporting hazardous alcohol use and eliminated gaps in ART uptake between PWH with hazardous and no/nonhazardous use. Patient-centered HIV care may decrease barriers to HIV care for PWH with hazardous alcohol use.

Determinants of Preexposure Prophylaxis Cascade Among Sexual and Gender Minorities in Nigeria

BACKGROUND

Preexposure prophylaxis (PrEP) is effective in preventing human immunodeficiency virus (HIV) infection among sexual and gender minorities (SGMs). We evaluated the characteristics associated with engagement in 7 steps of the PrEP cascade among SGMs in Nigeria.

METHODS

Sexual and gender minorities without HIV from the Abuja site of TRUST/RV368 cohort who were surveyed on awareness of and willingness to use PrEP were approached for PrEP initiation upon availability of oral daily PrEP. To understand gaps in the uptake of oral daily PrEP, we categorized the HIV PrEP cascade as (i) education about PrEP, (ii) interest in PrEP, (iii) successful contact, (iv) appointment scheduled, (v) appointment attendance, (vi) PrEP initiation, and (vii) plasma protective levels of tenofovir disoproxil fumarate. Multivariable logistic regression models were used to determine factors associated with each of the 7 steps in the HIV PrEP cascade.

RESULTS

Of 788 participants, 718 (91.1%) showed interest in taking oral daily PrEP every day and/or after a sexual act, 542 (68.8%) were successfully contacted, 433 (54.9%) scheduled an appointment, 409 (51.9%) attended a scheduled appointment, 400 (50.8%) initiated oral daily PrEP, and 59 (7.4%) had protective levels of tenofovir disoproxil fumarate. Of initiators of PrEP, 23 (5.8%) seroconverted at a rate of 13.9 cases/100 person-years. Better social support, larger network density, and higher education were associated with engagement in 4 to 5 components of the cascade.

CONCLUSIONS

Our data highlight a gap between willingness and actual PrEP use. Despite PrEP's effectiveness in preventing HIV, the optimal impact of PrEP for SGMs in sub-Saharan Africa will require multifaceted approaches that combine social support, education, and destigmatization.

Depression-Mediating Pathways From Household Adversity to Antiretroviral Therapy Nonadherence Among Children and Adolescents Living With HIV in Zambia: A Structural Equation Modeling Approach

BACKGROUND

In Zambia, half of children and adolescents living with HIV (CALWH) on antiretroviral therapy (ART) are virologically unsuppressed. Depressive symptoms are associated with ART nonadherence but have received insufficient attention as mediating factors in the relationship between HIV self-management and household-level adversities. We aimed to quantify theorized pathways from indicators of household adversity to ART adherence, partially mediated by depressive symptoms, among CALWH in 2 Zambian provinces.

SETTING

In July-September 2017, we enrolled 544 CALWH aged 5-17 years and their adult caregivers into a year-long prospective cohort study.

METHODS

At baseline, CALWH-caregiver dyads completed an interviewer-administered questionnaire, which included validated measures of recent (past 6 months) depressive symptomatology and self-reported past-month ART adherence (never versus sometimes or often missing medication doses). We used structural equation modeling with theta parameterization to identify statistically significant ( P < 0.05) pathways from household adversities (past-month food insecurity and caregiver self-reported health) to depression (modeled latently), ART adherence, and poor physical health in the past 2 weeks.

RESULTS

Most CALWH (mean age: 11 years, 59% female) exhibited depressive symptomatology (81%). In our structural equation model, food insecurity significantly predicted elevated depressive symptomatology ( ß = 0.128), which was associated inversely with daily ART adherence ( ß = -0.249) and positively with poor physical health ( ß = 0.359). Neither food insecurity nor poor caregiver health was directly associated with ART nonadherence or poor physical health.

CONCLUSIONS

Using structural equation modeling, we found that depressive symptomatology fully mediated the relationship between food insecurity, ART nonadherence, and poor health among CALWH.

Regional Variation in the Tumor Microenvironment, Immune Escape and Prognostic Factors in Breast Cancer in Sub-Saharan Africa

The low overall survival rates of patients with breast cancer in sub-Saharan Africa (SSA) are driven by regionally differing tumor biology, advanced tumor stages at diagnosis, and limited access to therapy. However, it is not known whether regional differences in the composition of the tumor microenvironment (TME) exist and affect patients' prognosis. In this international, multicentre cohort study, 1,237 formalin-fixed, paraffin-embedded breast cancer samples, including samples of the "African Breast Cancer-Disparities in Outcomes (ABC-DO) Study," were analyzed. The immune cell phenotypes, their spatial distribution in the TME, and immune escape mechanisms of breast cancer samples from SSA and Germany (n = 117) were investigated using histomorphology, conventional and multiplex IHC, and RNA expression analysis. The data revealed no regional differences in the number of tumor-infiltrating lymphocytes (TIL) in the 1,237 SSA breast cancer samples, while the distribution of TILs in different breast cancer IHC subtypes showed regional diversity, particularly when compared with German samples. Higher TIL densities were associated with better survival in the SSA cohort (n = 400), but regional differences concerning the predictive value of TILs existed. High numbers of CD163+ macrophages and CD3+CD8+ T cells accompanied by reduced cytotoxicity, altered IL10 and IFNγ levels and downregulation of MHC class I components were predominantly detected in breast cancer samples from Western SSA. Features of nonimmunogenic breast cancer phenotypes were associated with reduced patient survival (n = 131). We therefore conclude that regional diversity in the distribution of breast cancer subtypes, TME composition, and immune escape mechanisms should be considered for therapy decisions in SSA and the design of personalized therapies.

The Evolving Pediatric HIV Epidemic in Rural Southern Zambia: The Beneficial Impact of Advances in Prevention and Treatment at a District Hospital From 2007 to 2019

BACKGROUND

Remarkable progress has been made in expanding access to services addressing the pediatric HIV epidemic, including programs to prevent mother-to-child transmission, early diagnosis and treatment for children living with HIV. Few long-term data are available from rural sub-Saharan Africa to assess implementation and impact of national guidelines.

METHODS

Results from 3 cross-sectional studies and 1 cohort study conducted at Macha Hospital in Southern Province, Zambia from 2007 to 2019 were summarized. For infant diagnosis, maternal antiretroviral treatment, infant test results and turnaround times for results were evaluated by year. For pediatric HIV care, the number and age of children initiating care and treatment, and treatment outcomes within 12 months were evaluated by year.

RESULTS

Receipt of maternal combination antiretroviral treatment increased from 51.6% in 2010-2012 to 93.4% in 2019, and the proportion of infants testing positive decreased from 12.4% to 4.0%. Turnaround times for results returning to clinic varied but were shorter when labs consistently used a text messaging system. The proportion of mothers receiving results was higher when a text message intervention was piloted. The number of children living with HIV enrolled into care and the proportion initiating treatment with severe immunosuppression and dying within 12 months decreased over time.

CONCLUSIONS

These studies demonstrate the long-term beneficial impact of implementing a strong HIV prevention and treatment program. While expansion and decentralization brought challenges, the program succeeded in decreasing the rate of mother-to-child transmission and ensuring that children living with HIV benefit from access to life-saving treatment.

The impact of dietary and lifestyle interventions on blood pressure management in sub-Saharan Africa: a systematic review and metanalysis

OBJECTIVES

Current literature is lacking a comprehensive review of data on dietary interventions in blood pressure (BP) management in sub-Saharan African countries. We assessed the association of dietary and other lifestyle interventions with BP-lowering effects in populations within sub-Saharan Africa.

METHODS

We performed a systematic review and random-effects meta-analysis to determine the impact of dietary and lifestyle interventions on SBP and DBP in sub-Saharan Africa. We searched the MEDLINE, EMBASE, and Web of Science databases. We included intervention studies that were randomized and nonrandomized conducted in Africans residing in sub-Saharan Africa investigating diet and other lifestyle, physical activity, weight loss, tobacco, and alcohol cessation modifications. We determined the effect of diet and other lifestyle interventions on SBP and DBP. We expressed effect size as weighted mean difference and 95% confidence interval (CI).

MAIN RESULTS

: We identified six studies with a total of 1412 individuals, 38% males, mean age of 52.8 years (SD = 11.5). The weighted mean difference of dietary and other lifestyle interventions on SBP and DBP was -7.33 mmHg, (95% CI: -9.90 to -4.76, P  < 0.001) and -2.98 mmHg, (95% CI: -4.28 to -1.69, P  < 0.001), respectively. In the metaregression analyses, the duration of the interventions did not have any effect on changes in SBP and DBP.

PRINCIPAL CONCLUSION

: Dietary modifications showed a beneficial overall improvement in SBP and DBP in Africans. However, aside from low-salt interventions, studies on dietary potassium, healthy dietary patterns, and lifestyle modifications have not been investigated extensively in Africans and are in critical need. In addition, researchers will need to consider the settings (rural, urban, or semiurban) and the predominant existing dietary habits while designing studies on dietary interventions in sub-Saharan Africa.

Early Antiretroviral Therapy Reduces Severity but Does Not Eliminate Neurodevelopmental Compromise in Children With HIV

BACKGROUND

Early antiretroviral therapy (ART) during infancy reduces cognitive impairment due to HIV, but the extent of benefit is unclear.

SETTING

Children were recruited from hospital and health centers providing HIV care and treatment in Nairobi, Kenya.

METHODS

Cognitive, behavioral, and motor outcomes were assessed in children with HIV and early ART (<1 year), children with HIV and late ART (1.5-6 years), and children HIV-unexposed uninfected (CHUU). Domain z scores and odds neurobehavioral impairment (≤15th percentile in CHUU) were compared in adjusted analyses.

RESULTS

Children with HIV initiated ART at median ages 0.4 (early ART) and 3.5 years (late ART). Children were assessed at median ages 6.9 (CHUU, N = 61), 6.9 (early ART, N = 54), and 13.5 (late ART; N = 27) years. Children with late ART vs. children with early ART had significantly lower z scores in 7 domains, specifically global cognition, short-term memory, visuospatial processing, learning, nonverbal test performance, executive function, and motor skills (adjusted mean differences, -0.42 to -0.62, P values ≤ 0.05), and had higher odds impairment in 7 domains (adjusted odds ratios [aORs], 2.87 to 16.22, P values ≤ 0.05). Children with early ART vs. CHUU had lower z scores in 5 domains (global cognition, short-term memory, delayed memory, processing speed, and behavioral regulation [adjusted mean differences, -0.32 to -0.88, P values < 0.05]) and higher impairment for 2 domains (short-term memory [aOR, 3.88] and behavioral regulation [aOR 3.46], P values < 0.05). Children with late ART vs. CHUU had lower z scores in 8 domains (adjusted mean differences, -0.57 to -1.05, P values ≤ 0.05), and higher impairment in 7 domains (aORs 1.98 to 2.32, P values ≤ 0.05).

CONCLUSION

Early ART in the first year of life attenuates but does not eliminate the neurodevelopmental compromise of HIV.

Prevalence, Awareness, Treatment, Control of Hypertension, and Availability of Hypertension Services for Patients Living With Human Immunodeficiency Virus (HIV) in Sub-Saharan Africa (SSA): A Systematic Review and Meta-analysis

Sub-Saharan Africa (SSA) is faced with a dual burden of hypertension and human immunodeficiency virus (HIV). In this review we sought to determine the prevalence, awareness, and control of hypertension among persons living with HIV (PLHIV), and the availability of hypertension services at the HIV care points in SSA. We searched the PubMed, Embase, Scopus, Cochrane library, Global index Medicus, African Journal online, and WHO Institutional Repository for Information Sharing (IRIS) for studies on the epidemiology of hypertension, and hypertension services for PLHIV in SSA. Twenty-six articles were identified for the review, with 150,886 participants; weighted mean of age 37.5 years and female proportion of 62.6%. The pooled prevalence was 19.6% (95% confidence interval [CI], 16.6%, 22.5%); hypertension awareness was 28.4% (95% CI, 15.5%, 41.3%), and hypertension control was 13.4% (95% CI, 4.7%, 22.1%). HIV-related factors like CD4 count, viremia, and antiretroviral therapy regimen were not consistently associated with prevalent hypertension. However, high body mass index (BMI) above 25 kg/m² [odds ratio: 1.64, 95% CI (1.26, 2.02)] and age above 45 years [odds ratio: 1.44, 95% CI (1.08, 1.79)] were associated with prevalent hypertension. Even when PLHIV on ART were more likely to be screened for hypertension and monitored, there was infrequent screening and treatment of hypertension in most HIV clinics. Most studies recommended integrating of HIV and hypertension services. We report a high prevalence of hypertension in a relatively young population of PLHIV with suboptimal screening, treatment, and control of hypertension. We recommend strategies to integrate HIV and hypertension services.

Echocardiographic Correlates of Left Atrial Function Index Among Hypertensive Heart Failure Patients: A Cross-Sectional Study

Background Heart failure contributes to the global burden of cardiovascular diseases, with hypertensive heart failure affecting individuals in their productive age group and leading to high economic losses and disability-adjusted life years. The left atrium, on the other hand, contributes significantly to left ventricular filling in heart failure patients, and the left atrial function index is an excellent tool for assessing left atrial function among heart failure patients. The study aimed to evaluate some parameters of systolic and diastolic function as correlates and potential predictors of the left atrial function index among hypertensive heart failure cohorts. Materials and methods The study was conducted at Delta State University Teaching Hospital, Oghara. Eighty (80) patients with hypertensive heart failure who met the inclusion criteria were enrolled in the cardiology outpatient clinics. The left atrial function index was calculated using the following formula: LAFI = (LAEF x LVOT-VTI)/LAESVI. (LAFI = left atrial function index; LAEF = left atrial emptying fraction; LAESVI = left atrial end-systolic volume index; LVOTVTI = outflow tract velocity time integral). The data were analysed using IBM Statistical Product and Service Solution Version 22. Relationships between variables were determined using analysis of variance, Pearson correlation, and multiple linear regressions. Significance was assessed at p<0.05. Result It was discovered that the left atrial function index correlated with ejection fraction (r = 0.616, p = 0.001), fractional shortening (r = 0.462, p = 0.001), and the ratio of early transmitral flow to early myocardial contractility, E/E' (r = -0.522, p = 0.001). However, there was no correlation with stroke volume (r = 0.38, p = 0.11); the ratio of early transmitral flow to late transmitral flow, E/A (r = -0.10, p = 0.11); isovolumetric relaxation time, IVRT (r = -0.171, p = 0.11); and tricuspid annular plane systolic excursion, TAPSE (r = 0.185, p = 0.10). Of the variables that correlated with left atrial function index, left ventricular ejection fraction and the ratio of early transmitral flow to early myocardial contractility (E/E') were found to be independent predictors of left atrial function index. Conclusion Left ventricular ejection fraction and the ratio of early transmitral flow to early myocardial contractility reflect changes in the left atrial function index, and as such, they should be used as surrogates for its assessment, especially in low- and medium-income countries where left atrial function index estimation is not routinely done.

Hydroxyurea with dose escalation for primary stroke risk reduction in children with sickle cell anaemia in Tanzania (SPHERE): an open-label, phase 2 trial

BACKGROUND

Transcranial Doppler screening with chronic transfusions reduces stroke risk in children with sickle cell anaemia but is not feasible in low-resource settings. Hydroxyurea is an alternative treatment to decrease stroke risk. We aimed to estimate stroke risk in children with sickle cell anaemia in Tanzania and to determine the efficacy of hydroxyurea to decrease and prevent stroke.

METHODS

We did an open-label, phase 2 trial (SPHERE) at Bugando Medical Centre, Mwanza, Tanzania. Children aged 2-16 years with a diagnosis of sickle cell anaemia confirmed by haemoglobin electrophoresis were eligible for enrolment. Participants had transcranial Doppler ultrasound screening by a local examiner. Participants with elevated Doppler velocities, either conditional (170-199 cm/s) or abnormal (≥200 cm/s), received oral hydroxyurea starting at 20 mg/kg once daily and escalated every 8 weeks by 5 mg/kg per day to the maximum tolerated dose. Participants with normal Doppler velocities (<170 cm/s) received usual care from the sickle cell anaemia clinic and were rescreened after 12 months to determine whether they qualified for treatment on trial. The primary endpoint was change in transcranial Doppler velocity from the baseline visit to after 12 months of hydroxyurea treatment, analysed in all patients who had paired baseline and follow-up measurements collected after 12 months of treatment. Safety was analysed in the per-protocol population (all participants who received study treatment). This study is registered with ClinicalTrials.gov, NCT03948867.

FINDINGS

Between April 24, 2019, and April 9, 2020, 202 children were enrolled and had transcranial Doppler screening. Sickle cell anaemia was confirmed by DNA-based testing in 196 participants (mean age 6·8 years [SD 3·5], 103 [53%] were female, and 93 [47%] were male). At the baseline screening, 47 (24%) of 196 participants had elevated transcranial Doppler velocities (43 [22%] conditional, four [2%] abnormal); 45 initiated hydroxyurea at a mean dose of 20·2 mg/kg per day (SD 1·4) with escalation to a mean dose of 27·4 mg/kg per day (5·1) after 12 months. Treatment response was analysed after 12 months (± 1 month; median 11 months, IQR 11-12) and 24 months (±3 months; median 22 months, 22-22). Transcranial Doppler velocities decreased to a mean of 149 cm/s (SD 27) compared with 182 cm/s (12) at baseline, which was significantly lower than baseline (p<0·0001), with an average decline of 35 cm/s (SD 23) after 12 months of treatment in 42 participants with paired results available at baseline and 12 months. No clinical strokes occurred, and 35 (83%) of 42 participants reverted to normal transcranial Doppler velocities. Clinical adverse events were mild, and dose-limiting toxicities were uncommon. The most common grade 3 adverse events were malaria (12 [29%] episodes in 45 patients) and sepsis (13 [32%] episodes). There were three serious adverse events, none of which were treatment-related, and no treatment-related deaths occurred.

INTERPRETATION

Children with sickle cell anaemia in Tanzania have a high baseline stroke risk. Hydroxyurea at the maximum tolerated dose significantly lowers transcranial Doppler velocities and reduces primary stroke risk. Transcranial Doppler screening plus hydroxyurea at the maximum tolerated dose is an effective stroke prevention strategy, supporting wider hydroxyurea access for patients with sickle cell anaemia across sub-Saharan Africa.

The Place of Academia and Industry in the Adoption and Adaptation of Education Technologies (ICT) in the African Education Sector for a post COVID-19 Recovery

The COVID-19 pandemic disrupted livelihoods at different fronts and at varying degrees globally. The global education sector was one of the key sectors that bore the heaviest brunt, particularly in the teaching and learning delivery modes. For instance, digital educational technologies became vital methods for teaching and learning. In responses, a number of initiatives were adopted by countries to lend insight on how to cope with the emergent challenges, as well as how to alleviate the challenges brought about by the pandemic for a post-COVID-19 recovery and growth. In this paper, we explore the contribution of industry and academia on post-COVID-19 recovery and growth, with a special focus on education technologies (ICT)’s adoption and promotion of entrepreneurial efforts in Africa. To attain the paper's objective, we used a scoping review approach to obtain crucial literature from credible and relevant databases to demonstrate and deliver a succinct, stronger, and clear and clarified findings on the areas of focus. Additionally, we visited websites of certain international organizations that supported sub-Saharan Africa (SSA) countries in respond to the COVID-19 pandemic, specifically focusing on responses targeting the education sector. The findings highlighted in this paper reveals that both academia and industry have a significant contribution to building back better efforts for a post-COVID-19 recovery and growth. Such efforts operate within the realms of adoption and adaptation of technology in the education sector, and increased emphasis on involvement in entrepreneurship practices. The paper also offers salient recommendations on how to better improve academia and industry's involvement for a post-COVID-19 recovery and growth efforts.

Transplant: The Success of Renal Transplant Programs

In the absence of malignancy or other severe comorbidity, kidney transplantation offers better survival rates and quality of life than dialysis. Despite this survival advantage, many lower- and upper-middle-income countries do not offer adequate kidney transplant services. This is particularly troubling because end-stage kidney disease often is more common in these countries than in high-income countries and overall is less costly in the life of a patient. We describe the contrasting levels of provision of kidney transplantation in Mexico, India, Nigeria, Ghana, and Zimbabwe, and kidney transplant services for children in Africa.

How trauma patients die in low resource settings: Identifying early targets for trauma quality improvement

BACKGROUND

Injury deaths in sub-Saharan Africa are among the world's highest, but hospital data rarely have sufficient granularity to direct quality improvement. We analyzed clinical care patterns among trauma patients who died in a prospective, multicenter sub-Saharan cohort to pinpoint trauma quality improvement intervention targets.

METHODS

In-hospital trauma deaths in four Cameroonian hospitals between 2017 and 2019 were included. Trauma registry data on patient demographics, injury characteristics, and clinical care were analyzed to identify opportunities for systems improvements.

RESULTS

Among 9,423 trauma patients, there were 236 deaths. Overall, 83% of patients who died in the emergency department were living on arrival (LOA). Among 183 LOA patients, 30% presented with normal vital signs, but 11% had no vital signs taken, often because of lack of equipment (43%). Of LOA patients presenting with a Glasgow Coma Scale score of <9 (56%), few received neurosurgery consults (15%), C-collar placement (9%), or intubation (1%). The most common reason for lack of c-collar placement was failure to recognize that it was indicated (66%). Tracheal deviation, unequal breath sounds, or paradoxical chest movement were present in 63% of LOA patients, but only two patients had chest tubes placed. Hypotension or active bleeding was present in 80% of LOA patients; while crystalloid bolus was given to 96% of these patients, few received transfusion (8%), tourniquet placement for extremity injury (6%), or an operation (4%).

CONCLUSION

Primary survey interventions are underperformed in trauma nonsurvivors in Cameroon. Protocolizing early treatment for head injury, hemorrhagic shock, and chest wall trauma could reduce trauma mortality.

Brief Report: Dapivirine Ring HIV-1 Prevention Effectiveness for Women Engaged in Vaginal and Anal Intercourse: Insights From Mathematical Modeling

BACKGROUND

The dapivirine vaginal ring reduces the risk of HIV-1 acquisition in acts of vaginal intercourse (VI), and although it does not offer HIV-1 protection in acts of anal intercourse (AI), it may provide some overall risk reduction for women for whom most sex acts are vaginal. We estimated the protective effect of the ring among women with high ring adherence engaged in both VI and AI.

METHODS

We developed a microsimulation model using data from the MTN-020/ASPIRE trial. Among women who reported any AI, we estimated the proportion of all sex acts that were AI. Model scenarios varied this proportion among women engaged in both VI and AI from 5% to 30%, including the trial-observed median proportion of 6.3% of all acts being AI. In primary analyses, dapivirine ring efficacy was model-calibrated at 70% for vaginal exposures and assumed to be 0% for anal exposures.

RESULTS

Among highly adherent women for whom 6.3% of sex acts were AI, the ring reduced HIV-1 risk by 53% (interquartile range: 44, 60), with a decline to 26% (interquartile range: 16, 36) among women for whom 30% of acts were AI. Ring effectiveness was less than 40% among women for whom AI accounted for greater than 16% of all sex acts, although this represented less than 5% of all women in the ASPIRE trial.

CONCLUSIONS

For most women, including those who engage in AI, because most HIV-1 risk occurs in acts of vaginal sex, the dapivirine vaginal ring can provide important HIV-1 protection.

Male partner age, viral load, and HIV infection in adolescent girls and young women: evidence from eight sub-Saharan African countries

OBJECTIVE

We aimed to elucidate the role of partnerships with older men in the HIV epidemic among adolescent girls and young women (AGYW) aged 15-24 years in sub-Saharan Africa.

DESIGN

Analysis of Population-based HIV Impact Assessments in Eswatini, Lesotho, Malawi, Namibia, Tanzania, Uganda, Zambia, and Zimbabwe.

METHODS

We examined associations between reported partner age and recent HIV infection among AGYW, incorporating male population-level HIV characteristics by age-band. Recent HIV infection was defined using the LAg avidity assay algorithm. Viremia was defined as a viral load of more than 1000 copies/ml, regardless of serostatus. Logistic regression compared recent infection in AGYW with older male partners to those reporting younger partners. Dyadic analysis examined cohabitating male partner age, HIV status, and viremia to assess associations with AGYW infection.

RESULTS

Among 17 813 AGYW, increasing partner age was associated with higher odds of recent infection, peaking for partners aged 35-44 (adjusted odds ratio = 8.94, 95% confidence interval: 2.63-30.37) compared with partners aged 15-24. Population-level viremia was highest in this male age-band. Dyadic analyses of 5432 partnerships confirmed the association between partner age-band and prevalent HIV infection (male spousal age 35-44-adjusted odds ratio = 3.82, 95% confidence interval: 2.17-6.75). Most new infections were in AGYW with partners aged 25-34, as most AGYW had partners in this age-band.

CONCLUSION

These results provide evidence that men aged 25-34 drive most AGYW infections, but partners over 9 years older than AGYW in the 35-44 age-band confer greater risk. Population-level infectiousness and male age group should be incorporated into identifying high-risk typologies in AGYW.

A Systems-Based Framework for Immunisation System Design: Six Loops, Three Flows, Two Paradigms

Despite massive progress in vaccine coverage globally, the region of sub-Saharan Africa is lagging behind for Sustainable Development Goal 3 by 2030. Sub-national under-immunisation is part of the problem. In order to reverse the current immunisation system's (IMS) underperformance, a conceptual model is proposed that captures the complexity of IMSs in low- and middle-income countries (LMICs) and offers directions for sustainable redesign. The IMS model was constructed based on literature and stakeholder interaction in Rwanda and Kenya. The model assembles the paradigms of planned and emergency immunisation in one system and emphasises the synchronised flows of vaccinee, vaccinator and vaccine. Six feedback loops capture the main mechanisms governing the system. Sustainability and resilience are assessed based on loop dominance and dependency on exogenous factors. The diagram invites stakeholders to share their mental models and. The framework provides a systems approach for problem structuring and policy design.

Weight Gain Among Treatment-Naïve Persons With HIV Receiving Dolutegravir in Kenya

BACKGROUND

Several recent studies have linked integrase strand transfer inhibitors (INSTI) with increased weight gain.

SETTING

The effects of sex on weight gain with dolutegravir (DTG)-based antiretroviral therapy (ART) among treatment-naïve participants in a lower-income, sub-Saharan population with high rates of pre-ART underweight and tuberculosis (TB) coinfection are unknown.

METHODS

Our analysis included treatment-naïve participants in Kenya and starting their first treatment regimen between January 1, 2015, and September 30, 2018. Participants were grouped into 2 cohorts based on the initial treatment regimen [DTG vs. nonnucleoside reverse transcriptase inhibitors (NNRTI)]. We modelled weight changes over time using a multivariable nonlinear mixed-effect model, with participant as a random effect. Logistic regression models were constructed to evaluate the association between different variables with extreme increase in body mass index (≥10% increase).

RESULTS

Seventeen thousand forty-four participants met our inclusion criteria. Sixty-two percent of participants were women, 6% were receiving active TB therapy, and 97% were on NNRTI-based regimens. Participants starting DTG-based regimens were more likely to gain weight when compared with participants starting NNRTI-based regimens. Female participants starting DTG-based regimens experienced the highest weight gain compared with other participants (mean gain of 6.1 kgs at 18 months). Female participants receiving DTG-based regimens, along with participants with lower CD4 cell counts, underweight at baseline, and those receiving active TB therapy were also at higher risk for extreme body mass index increase.

CONCLUSIONS

Our study in a lower-income sub-Saharan African population confirms higher weight gain with DTG-based regimens compared with traditional ART for treatment-naïve patients.

Risk factors and prognostic significance of anemia in children with HIV infection on antiretroviral therapy

OBJECTIVES

To establish the incidence, risk factors and prognostic effect of anemia in children living with HIV (CLWH).

DESIGN

Retrospective nested case-control study of patients 0-18 years in five centers in sub-Saharan Africa, 2004-2014.

METHODS

Incident cases of anemia were identified from electronic records and matched with CLWH without anemia. We calculated the incidence density of anemia and used conditional logistic regression to evaluate its association with risk factors, stratified by severity and type of anemia. We used a Cox proportional hazards model to evaluate the impact of anemia on survival.

RESULTS

Two thousand, one hundred and thirty-seven children were sampled. The incidence density of anemia was 1 per 6.6 CLWH-years. Anemia was moderate in 31.8% and severe in 17.3% of anemia cases, which had 10-year mortality hazards of 3.4 and 4.5, respectively. Microcytic anemia (36% cases) was associated with 2.3-fold hazard of 10-year mortality, and with malnutrition and CD4 + suppression. Normocytic anemia (50.5% cases) was associated with 2.6-fold hazards of 10-year mortality, and with more severe malnutrition, CD4 + suppression, and WHO stage, but inversely associated with lamivudine and nevirapine therapy. Macrocytic anemia (13.5% cases) was neither associated with higher 10-year mortality nor with severe malnutrition or CD4 + suppression but was associated with WHO stage II/III and negatively associated with lamivudine therapy.

CONCLUSION

This large multicountry study of CLWH found a high incidence density of anemia. Higher severity, normocytic and microcytic types of anemia were independently associated with long-term mortality. Laboratory studies are needed to decipher the mechanisms of anemia and how it impacts mortality in CLWH.

Transition to independent care for youth living with HIV: a cluster randomised clinical trial

BACKGROUND

Transitioning youth living with HIV to adult care is a crucial step in the HIV care continuum; however, tools to support transition in sub-Saharan Africa are insufficient. We assessed the effectiveness of an adolescent transition package (ATP) to improve youth readiness for transition to independent HIV care.

METHODS

In this hybrid type 1, multicentre, cluster randomised clinical trial, we assessed the effectiveness of an ATP (administered by routine clinic staff, which included standardised assessments and chapter books to guide discussions at scheduled clinic visits) in four counties in Kenya, with HIV clinics randomly assigned 1:1 to ATP or control (standard-of-care practice). Clinics were eligible to participate if they had at least 50 youth (aged 10-24 years) living with HIV enrolled in care. We used restricted randomisation to achieve cluster balance and an independent biostatistician used computer-generated random numbers to assign clinics. We excluded very large clinics with more than 1000 youth, clinics with fewer than 50 youth, paediatric-only clinics, clinics with logistical challenges, and the smallest clinics in Homa Bay county. Youth were eligible for the transition intervention if they were enrolled in participating clinics, were aged 15-24 years, and were aware of their positive HIV diagnosis. Study staff assessed transition readiness scores overall and by four domains (HIV literacy, self-management, communication, and support) in youth with HIV, which were then compared between groups by use of mixed-effects linear regression models. Analysis was by intention-to-treat and was adjusted for multiple comparisons. This trial is registered with ClinicalTrials.gov, NCT03574129.

FINDINGS

We identified 35 clinics in four counties; of these, ten were assigned to the intervention group and ten to the control group. Of 1066 youth with HIV enrolled between Nov 1, 2019, and March 18, 2020, 578 (54%) were in intervention and 488 (46%) in control sites. Mean baseline transition readiness score was 12·1 (SD 3·4) in ATP sites and 11·4 (3·7) in control sites. At 1 year, adjusting for baseline scores, age, and months since HIV disclosure, participants in the ATP group had significantly higher overall transition readiness scores (adjusted mean difference 1·7, 95% CI 0·3-3·1, p=0·024), and higher scores in HIV literacy domain (adjusted mean difference 1·0, 0·2-1·7, p=0·011). At 12 months, 15 serious adverse events were recorded, none of which were thought to be related to study participation.

INTERPRETATION

Integrating ATP approaches could enhance long-term HIV care in youth with HIV as they age into adulthood.

Cost-effectiveness of single, high-dose, liposomal amphotericin regimen for HIV-associated cryptococcal meningitis in five countries in sub-Saharan Africa: an economic analysis of the AMBITION-cm trial

BACKGROUND

HIV-associated cryptococcal meningitis is a leading cause of AIDS-related mortality. The AMBITION-cm trial showed that a regimen based on a single high dose of liposomal amphotericin B deoxycholate (AmBisome group) was non-inferior to the WHO-recommended treatment of seven daily doses of amphotericin B deoxycholate (control group) and was associated with fewer adverse events. We present a five-country cost-effectiveness analysis.

METHODS

The AMBITION-cm trial enrolled patients with HIV-associated cryptococcal meningitis from eight hospitals in Botswana, Malawi, South Africa, Uganda, and Zimbabwe. Taking a health service perspective, we collected country-specific unit costs and individual resource-use data per participant over the 10-week trial period, calculating mean cost per participant by group, mean cost-difference between groups, and incremental cost-effectiveness ratio per life-year saved. Non-parametric bootstrapping and scenarios analyses were performed including hypothetical real-world resource use. The trial registration number is ISRCTN72509687, and the trial has been completed.

FINDINGS

The AMBITION-cm trial enrolled 844 participants, and 814 were included in the intention-to-treat analysis (327 from Uganda, 225 from Malawi, 107 from South Africa, 84 from Botswana, and 71 from Zimbabwe) with 407 in each group, between Jan 31, 2018, and Feb 17, 2021. Using Malawi as a representative example, mean total costs per participant were US$1369 (95% CI 1314-1424) in the AmBisome group and $1237 (1181-1293) in the control group. The incremental cost-effectiveness ratio was $128 (59-257) per life-year saved. Excluding study protocol-driven cost, using a real-world toxicity monitoring schedule, the cost per life-year saved reduced to $80 (15-275). Changes in the duration of the hospital stay and antifungal medication cost showed the greatest effect in sensitivity analyses. Results were similar across countries, with the cost per life-year saved in the real-world scenario ranging from $71 in Botswana to $121 in Uganda.

INTERPRETATION

The AmBisome regimen was cost-effective at a low incremental cost-effectiveness ratio. The regimen might be even less costly and potentially cost-saving in real-world implementation given the lower drug-related toxicity and the potential for shorter hospital stays.

Findings from a mixed-methods journey map study of barriers to family planning in western Kenya

Our objective was to map and prioritize barriers to high-quality family planning care in western Kenya. We conducted key informant interviews (n = 19); focus group discussions with clients (n = 55); mystery client visits (n = 180); unannounced visitors (n = 120); and direct observation of client-provider interactions (n = 256) at public facilities offering family planning. We synthesized the data into a client and a provider journey map, which we used to facilitate client (n = 9) and provider (n = 12) discussions. For both groups, stockouts were frequent, impactful, and important barriers. Clients also reported male partner resistance, insufficient counseling, and informal fees were priority barriers.

How a Digital Case Management Platform Affects Community-Based Palliative Care of Sub-Saharan African Cancer Patients: Clinician-Users' Perspectives

Background  Symptom control among cancer patients is a Tanzanian public health priority impacted by limited access to palliative care (PC) specialists and resources. Mobile Palliative Care Link (mPCL), a mobile/web application, aims to extend specialist access via shared care with local health workers (LHWs) with the African P alliative care O utcome S cale (POS) adapted for regular, automated symptom assessment as a core feature.

Objective  The aim of the study is to assess clinicians' attitudes, beliefs, and perceptions regarding mPCL usability and utility with their patients within a government-supported, urban Tanzanian cancer hospital setting.

Methods  We used a mixed methods approach including surveys, qualitative interviews, and system usage data to assess clinicians' experience with mPCL in a field study where discharged, untreatable cancer patients were randomized to mPCL or phone-contact POS collection.

Results  All six specialists and 10 LHWs expressed overall satisfaction with mPCL among 49 intervention arm patients. They perceived mPCL as a way to stay connected with patients and support remote symptom control. Timely access to POS responses and medical records were identified as key benefits. Some differences in perceptions of mPCL use and utility were seen between clinician groups; however, both expressed strong interest in continuing app use, recommending it to colleagues, and extending use throughout Tanzania. Primary use was for clinical status communication and care coordination. Pain and other symptom progression were the most frequently reported reasons for provider–patient interactions accounting for 34% ( n  = 44) and 12% ( n  = 15) of reasons, respectively. Usage barriers included time required to create a new clinical record, perceived need for response to non-urgent reminders or alerts, and training. necessary for competent use. System-level implementation barriers included variable patient access to smartphones and SIM cards and unreliable Internet access.

Conclusion  This work demonstrates broad clinician desire for digital health tools to support remote community-based PC among cancer patients, particularly pain management.

Uptake of and adherence to oral pre-exposure prophylaxis among adolescent girls and young women at high risk of HIV-infection in Kampala, Uganda: A qualitative study of experiences, facilitators and barriers

Background

There is limited information on factors that influence oral pre-exposure prophylaxis (PrEP) uptake and adherence among adolescent girls and young women (AGYW). We conducted a qualitative methods study to explore experiences, facilitators and barriers of PrEP uptake and adherence to PrEP among AGYW at risk of Human Immunodeficiency Virus (HIV) infection in Kampala, Uganda.

Methods

This study was nested in a prospective cohort study that offered daily oral PrEP to AGYW. Between April 2019 and October 2020 we conducted in-depth interviews with 26 AGYW aged 14–24 years who had been offered or had been using PrEP for at least 6 months, including PrEP adherers (8), non-adherers (8) and those who had declined PrEP (10). After 12 months, follow-up interviews were conducted with 12 AGYW who had adhered to PrEP and those who had dropped it. Thematic analysis was conducted and data were further examined and categorized into the 5 constructs of the Socio-Ecological Model (SEM).

Results

PrEP uptake and adherence were facilitated by factors including: perceptions that one’s own or partner’s sexual behaviour was high risk, a negative attitude towards condoms, social support and wanting to maintain a negative HIV status after receiving a negative HIV test result. Good adherence to PrEP was enabled by effective counselling, support tools such as alarms and phone reminders and incentives like free treatment for STIs and other illnesses during study visits. Barriers to uptake included: anxiety about the pill burden, perceptions of being too young for PrEP and fear of being labelled `prostitute’ or `HIV positive’. Poor adherence was attributed to doubt over the efficacy of PrEP as a result of beliefs that because HIV was incurable, no medicine could prevent it. Alcohol use, side effects experienced, and mobility all had a negative impact on adherence. The majority of PrEP users reported feeling safe as a result of using PrEP which had both good and negative implications on their sexual behaviour, specifically the number of sexual partners and condom use.

Conclusion

Addressing community misconceptions to maximize uptake of PrEP among AGYW is important. Targeted education messages, and counselling to address misconceptions in ways that capture the attention of AGYW in communities are required.

Feasibility, Acceptability, and Potential Cost-Effectiveness of a Novel Mobile Phone Intervention to Promote Human Immunodeficiency Virus Testing Within Social Networks in Tanzania

ABSTRACT

Among 145 individuals surveyed in Tanzania, 42% indicated willingness to test for human immunodeficiency virus in response to a confidential, phone-based text message. On average, participants were likely to provide contact information for 1.5 members of their social networks, suggesting high feasibility and moderate acceptability of a novel mHealth human immunodeficiency virus testing intervention.

Assisted Partner Services for People Who Inject Drugs: Index Characteristics Associated With Untreated HIV in Partners

BACKGROUND

Assisted partner services (APSs) is a feasible, acceptable, and effective strategy that increases uptake of HIV testing; however, it has not been used widely among people who inject drugs (PWID) in Africa to notify sexual and injecting partners of potential exposures to HIV and provide testing services.

SETTING

Nairobi, Kilifi, and Mombasa counties in Kenya.

METHODS

PWID living with HIV (indexes) were enrolled and asked to provide contact information for sexual and injecting partners who were traced and offered HIV testing. APS efficiency was assessed by the number of indexes needed to interview (NNTI) to find 1 additional partner who was unaware of their HIV status or not on antiretroviral therapy (ART). We defined index participant characteristics associated with greater efficiency, defined as lower NNTIs.

RESULTS

Among 783 indexes, the NNTI to identify one partner unaware of their HIV status was 7.1 and to identify one HIV-positive partner not on ART (regardless of status awareness) was 4.1. APS was provided to 977 partners and was more efficient in identifying partners who were not on ART (n = 201) among indexes who were female (NNTI = 2.9 vs. 5.7, P < 0.001), unaware of their HIV status (NNTI = 2.2 vs. 4.2, P = 0.009), not on ART (NNTI = 2.1 vs. 4.9; P < 0.001), not enrolled in a methadone program (NNTI = 3.3 vs. 10.4, P < 0.001), reported injecting <5 years (NNTI = 3.3 vs. 5.0; P = 0.005), or from Nairobi (NNTI = 3.2 vs. 5.6, P < 0.001).

CONCLUSION

Scaling up APS among PWID living with HIV with certain characteristics could result in more efficient APS and greater partner engagement in HIV care.

Understanding the pathways leading to socioeconomic inequalities in HIV testing uptake in 18 sub-Saharan African countries

OBJECTIVE

To better understand the different pathways linking socioeconomic position and HIV testing uptake in 18 sub-Saharan African countries.

DESIGN

We used cross-sectional population-based surveys between 2010 and 2018.

METHODS

Using a potential outcomes framework and the product method, we decomposed the total effect linking wealth and recent (<12 months) HIV testing into direct effects, and indirect effects, via internal (related to individual's ability to perceive need for and to seek care) or external (ability to reach, pay for and engage in healthcare) mediators to calculate the proportion mediated (PM) by each mediator.

RESULTS

High levels of inequalities were observed in nine and 15 countries among women and men, respectively. The mediator indirect effect varied greatly across countries. The PM tended to be higher for internal than for external mediators. For instance, among women, HIV-related knowledge was estimated to mediate up to 12.1% of inequalities in Côte d'Ivoire; and up to 31.5% for positive attitudes towards people with HIV (PWH) in Senegal. For the four external mediators, the PM was systematically below 7%. Similar findings were found when repeating analyses on men for the internal mediators, with higher PM by attitudes towards PWH (up to 39.9% in Senegal).

CONCLUSIONS

Our findings suggest that wealth-related inequalities in HIV testing may be mediated by internal more than external characteristics, with important variability across countries. Overall, the important heterogeneities in the pathways of wealth-related inequalities in HIV testing illustrate that addressing inequalities requires tailored efforts and upstream interventions.

Industrial mining and HIV risk: evidence from 39 mine openings across 16 countries in sub-Saharan Africa

OBJECTIVES

The aim of this study was to assess the impact of natural resource extraction projects on HIV transmission risks in local communities in sub-Saharan Africa.

DESIGN

Difference-in-differences design using repeated cross-sectional data from around newly opened mines.

METHODS

We combined data on mine openings with HIV data from the Demographic and Health Surveys (DHS). Using logistic regression models, we compared HIV-related indicators between mining (i.e. up to 10 km distance from the mine) and comparison (i.e. 10-50 km) areas before and after mine opening to identify their impact on HIV prevalence, sexual behavior and HIV knowledge.

RESULTS

A total of 33 086 individuals across 39 mine openings were analyzed. Adjusting for baseline differences and temporal trends in the study regions, mine opening increased the odds of HIV infection almost two-fold [odds ratio (OR): 1.93, 95% confidence interval (CI): 1.19-3.14]. Strongest effects were seen in high-prevalence countries and in the 20-29 years age group. In mining communities around operational mines, there was a tendency towards lower HIV knowledge (OR: 0.81, 95% CI: 0.63-1.04). New mine openings increased the odds of risky sexual behaviors, such as having multiple sex partners (OR: 1.61, 95% CI: 1.02-2.55), high-risk sexual partners (OR: 1.45, 95% CI: 1.03-2.05) and unprotected sex with high-risk partners (OR: 1.77, 95% CI: 1.18-2.67).

CONCLUSION

The findings suggest that in our sample of households surrounding industrial mines, HIV infection risks substantially increase upon mine opening. Existing strategies for addressing mining-related risks for HIV transmission seem to be insufficient. Further efforts for mitigating and monitoring impacts of mines are needed.

Trajectories and predictors of perinatal depressive symptoms among Kenyan women: a prospective cohort study

BACKGROUND

There are gaps in understanding longitudinal patterns and predictors of perinatal depressive symptoms in sub-Saharan Africa. This study aimed to explore trajectories of depressive symptoms and associated factors from pregnancy to 9 months post partum among Kenyan women.

METHODS

In this prospective cohort study, we analysed data from the PrEP Implementation for Mothers in Antenatal Care (PrIMA) study in which HIV-negative women were enrolled in pregnancy and followed up to 9 months post partum in 20 public sector maternal-child health clinics in western Kenya. Pregnant women were eligible for enrolment if they were not infected with HIV, aged 15 years or older, and were able to provide consent. Eligible participants were screened and enrolled between Jan 15, 2018, and July 31, 2019, and followed up to 9 months post partum, with the last participant study visit conducted on Jan 15, 2021. Study nurses serially assessed depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CESD-10), intimate partner violence with the Hurt, Insult, Threaten, Scream scale, and social support with the Medical Outcomes Study scale. Generalised estimating equations were used to identify correlates of moderate-to-severe depressive symptoms (CESD-10 score ≥10) and group-based trajectory modelling identified discrete trajectories of perinatal depressive symptoms.

FINDINGS

Among 4447 participants in the main PrIMA study, 3555 had complete depressive symptom data in pregnancy and depressive symptom data post partum and were included in the primary analysis. Median age was 24·0 years (IQR 21·0-28·7), 1330 (38%) participants had low social support, and 278 (8%) reported intimate partner violence in pregnancy. All participants (100%) were female and all (100%) were of African Kenyan ethnicity. Prevalence of moderate-to-severe depressive symptoms was higher in pregnancy than post partum (870 [24·5%; 95% CI 23·1-25·9] vs 597 [6·8%; 15·6-18·1]; p<0·0001). Five patterns of depressive symptoms were identified; persistent moderate-to-severe depressive symptoms in pregnancy and post partum (295 [8·3%]), moderate-to-severe depressive symptoms in pregnancy that resolved post partum (139 [3·9%]), moderate-to-severe depressive symptoms that emerged post partum (40 [1·1%]), chronically mild symptoms (2709 [76·2%]), and no depressive symptoms (372 [10·5%]). Emergent moderate-to-severe depressive symptoms were associated with older age. Emergent, persistent, and resolving moderate-to-severe depressive symptoms were associated with intimate partner violence during pregnancy; and persistent and resolving moderate-to-severe depressive symptoms were associated with low social support and high HIV risk (all p<0·05). Moderate-to-severe depressive symptom risk was significantly increased with intimate partner violence (adjusted odds ratio 2·07 [95% CI 1·81-2·31]; p<0·0001), low social support (1·74 [1·56-1·95]; p<0·0001), and partner HIV-positive status (1·48 [1·22-1·78]; p<0·0001). 23·34% (95% CI 18·77-27·65) of cases of perinatal moderate-to-severe depressive symptoms were attributable to low social support.

INTERPRETATION

One third of women had perinatal moderate-to-severe depressive symptoms; nearly half of these had higher severity phenotypes of resolving, persistent, and emerging moderate-to-severe depressive symptoms that might require tailored interventions. Perinatal women with comorbid psychosocial stressors such as intimate partner violence and previous pregnancy loss should be prioritised for mental health services that augment social support within routine maternal-child health care.

Incident HIV Infection Among Young Men Associated With Female Sexual Partner Types Identified Through Latent Class Analysis, Rakai, Uganda

BACKGROUND

Sexual partner characteristics are important determinants of HIV acquisition, but little is known about partner types of young men in sub-Saharan Africa.

METHODS

Sexually active men aged 15-24 years from 5 rounds (2005-2013) of the Rakai Community Cohort Study in Uganda reported characteristics of up to 4 past-year female partners. Partner types were identified using latent class analysis. HIV incidence rates (IRs) were calculated by partner-type combinations, and individual-level risk adjusted IR ratios (aIRRs) relative to the lowest incidence type were estimated using the Poisson regression with generalized estimating equations.

RESULTS

Young men (N = 1771) reported 4539 past-year female sexual partners. Three partner types were identified: type A: noncohabiting, student, medium duration partnerships; type B: cohabiting, nonstudent, longer duration partnerships; and type C: noncohabiting, nonstudent shorter duration partnerships. Type C partners engaged in the most HIV-related risk behaviors. Many men (29%) had more than 1 partner type/round. IR overall was 9.8/1000 person-years [95% confidence interval (CI): 4.7 to 20.6]. IR was 4.0 (95% CI: 1.2 to 12.7) for men with type A partners alone (41% of men). Relative to them, IR for those with type B partners alone (25%) was not significantly different. Men with type C partners alone (5%) had higher risk (aIRR = 3.2; 95% CI: 1.0 to 9.9), as did men with >1 partner type, including men with both type A and type B partners (12%; aIRR = 6.3; 95% CI: 2.5 to 15.9) and men with type C and other partner types (17%; aIRR = 4.3; 95% CI: 1.7 to 10.8).

CONCLUSIONS

Partner-type combination was strongly associated with HIV incidence; type C partners and having more than 1 partner type were the riskiest patterns.

Results of the Kigali Imbereheza Project: A 2-Arm Individually Randomized Trial of TI-CBT Enhanced to Address ART Adherence and Mental Health for Rwandan Youth Living With HIV

BACKGROUND

Adolescents living with HIV have elevated mental distress and suboptimal antiretroviral therapy (ART) adherence.

SETTING

Two urban clinics in Kigali, Rwanda.

METHODS

A 2-arm individual randomized controlled trial compared Trauma-Informed Cognitive Behavioral Therapy enhanced to address HIV (TI-CBTe) with usual care (time-matched, long-standing, unstructured support groups) with 356 12- to 21-year-old (M = 16.78) Rwandans living with HIV. TI-CBTe included 6 group-based 2-hour sessions led by trained and supervised 21- to 25-year-old Rwandans living with HIV. Participants reported their ART adherence, depression/anxiety, and Post-Traumatic Stress Disorder symptoms at baseline, 6, 12, and 18 months.

RESULTS

ART adherence was relatively high at baseline, and youth reported elevated rates of depression/anxiety and trauma symptoms. There were no differential treatment effects on adherence, but depression/anxiety improved over time. Youth with lower depression/anxiety at baseline seemed to benefit more from TI-CBTe than usual care, whereas women with high baseline distress seemed to benefit more from usual care. Youth were less likely to score in high Post-Traumatic Stress Disorder symptom categories at the follow-up, with no differential treatment effects.

CONCLUSIONS

TI-CBTe did not outperform usual care on ART adherence, possibly reflecting relatively high adherence at baseline, simplified medication regimens over time, a strong comparison condition, or because youth assigned to TI-CBTe returned to their support groups after the intervention. TI-CBTe was more effective for youth with lower depression/anxiety symptoms, whereas youth with high distress benefitted more from the support groups. TI-CBTe was feasible and acceptable, and young adults living with HIV were able to deliver a mental health intervention with fidelity. The powerful nature of the comparison group, ongoing support groups, points to the potential value of locally crafted interventions in low-resource settings.

Evaluating the Jaccard Similarity Index as a Persistence Measure of Multiple Anal Human Papillomavirus Among Nigerian Men Who Have Sex With Men

BACKGROUND

Multiple anal human papillomavirus (HPVs) may increase the risk of anal cancer among men who have sex with men (MSM) living with human immunodeficiency virus (HIV). The Jaccard Similarity Index (JSI) was explored as a measure of multiple HPV persistence.

METHODS

The TRUST/RV368 cohort enrolled MSM living with and without HIV in Abuja and Lagos, Nigeria. Participants with anal swabs at baseline, 3- and 12-month visits were tested for high- and low-risk HPVs using a next-generation sequencing assay. Persistence of the same HPV genotypes over time was calculated using the JSI and categorized into high, medium, and low similarity tertiles. Factors associated with higher versus lower similarity were estimated with multivariable ordinal logistic regression and reported as adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

RESULTS

Of the 225 participants, median age was 25 years (interquartile range, 22-29 years), 62% were living with HIV, median HPVs was 3 (interquartile range, 2-5), and HPV6 (28%), HPV16 (26%), HPV11 (23%), and HPV45 (20%) were most prevalent. Fifty-three percent of participants had highly similar HPVs at 3 months, and the similarity was associated with HIV (aOR, 3.11; 95% CI, 1.6-5.9) and recent receptive sex (aOR, 1.9; 95% CI, 1.0-3.5). By 12 months, 20% had highly similar HPVs, and it was associated with 12 years or longer since anal coital debut (aOR, 6.8; 95% CI, 3.1-5.2), self-reported genital warts (aOR, 3.1; 95% CI, 1.5-6.6), and 200 or less CD4 cells/mm3 (aOR, 13.3; 95% CI, 2.7-65.2) for those living with HIV.

CONCLUSIONS

Studies evaluating the JSI as a predictor of high-grade intraepithelial lesions would further confirm its applicability as a quantitative measure of multiple HPV persistence.

Lower Neurocognitive Functioning in HIV-Exposed Uninfected Children Compared With That in HIV-Unexposed Children

BACKGROUND

Perinatal HIV and antiretroviral therapy exposure may influence neurocognitive outcomes, although evidence is mixed and most studies are limited to outcomes in the first 24 months. We compared neurocognitive outcomes in school-aged children who were HIV exposed uninfected (CHEU) with those in children who were HIV unexposed uninfected (CHUU).

SETTING

Children were recruited from a health center in Nairobi, Kenya.

METHODS

Key inclusion criteria were children aged 5-12 years and confirmed child and maternal HIV status; for CHEU, mothers reported knowing HIV-positive status before or at delivery of the index child. Children underwent a detailed battery of neuropsychological tests and behavioral assessment, and comparisons of scores between CHEU and CHUU were conducted using linear regression.

RESULTS

Among 56 CHEU and 65 CHUU, the median age and sex distributions were 6.8 and 7.0 years (P = 0.8) and 48% and 60% girls (P = 0.2), respectively. In analyses adjusted for child's age and sex and caregiver's age, education, and household rent, CHEU had significantly lower mean z scores for global cognitive ability than CHUU [-0.35, 95% confidence interval (CI): -0.64 to -0.05; P = 0.02], short-term memory (-0.44, 95% CI: -0.76 to -0.12; P = 0.008), delayed memory (-0.43, 95% CI: -0.79 to -0.08; P = 0.02), attention (-0.41, 95% CI: -0.78 to -0.05; P = 0.03), and processing speed (-0.76, 95% CI: -1.37 to -0.16; P = 0.01). Models adjusted for child nutritional status, household food security, and orphanhood yielded similar results.

CONCLUSIONS

Children exposed to HIV had poorer long-term neurocognitive outcomes than CHUU. These data suggest that long-term studies of neurocognitive and educational attainment in CHEU are warranted.

Curable sexually transmitted infections among women with HIV in sub-Saharan Africa

OBJECTIVES

Sexually transmitted infections (STIs) cause significant morbidity among women with HIV and increase HIV transmission. We estimated the prevalence of four STIs among women with HIV in sub-Saharan Africa (SSA) and compared prevalence among women with and without HIV.

DESIGN

Systematic review and meta-analysis.

METHODS

We searched for studies published 1 January 1999 to 19 December 2019 reporting prevalence of gonorrhea, chlamydia, trichomoniasis, or Mycoplasma genitalium among women with HIV in SSA. We excluded studies conducted in high-risk groups (e.g. female sex workers). We extracted data on laboratory-confirmed STIs among women with HIV, and when included, among women without HIV. We estimated pooled prevalence for each STI among women with HIV using inverse variance heterogeneity meta-analysis, compared prevalence to women without HIV, and examined the influences of region, clinical setting, and pregnancy status in subgroup analyses.

RESULTS

We identified 3756 unique records; 67 studies were included in the meta-analysis. Prevalence of gonorrhea, chlamydia, trichomoniasis, and M. genitalium was 3.5, 4, 15.6, and 10.2%, respectively. Chlamydia prevalence was lower in Eastern (2.8%) than in Southern (12.5%) and West/Central (19.1%) Africa combined. Prevalence of chlamydia and trichomoniasis was higher among pregnant (8.1%, 17.6%) than nonpregnant (1.7%, 12.3%) women. All STIs were more prevalent among women with than without HIV (relative risks ranging 1.54-1.89).

CONCLUSION

STIs are common among women with HIV in SSA, and more common among women with than without HIV. Integrated STI and HIV care could substantially impact STI burden among women with HIV, with potential downstream impacts on HIV transmission.

Chronic obstructive pulmonary disease in sub-Saharan Africa

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide and an important cause of death in sub-Saharan Africa (SSA). We conducted a systematic review and meta-analysis on the prevalence of and risk factors for COPD in SSA.METHODS: We conducted a protocol-driven systematic literature search in MEDLINE, EMBASE, CINAHL and Global Health, supplemented by a manual search of the abstracts from thoracic conference proceedings from 2017 to 2020. We did a meta-analysis of COPD prevalence and its association with current smoking.RESULTS: We identified 831 titles, of which 27 were eligible for inclusion in the review and meta-analysis. The population prevalence of COPD ranged from 1.7% to 24.8% (pooled prevalence: 8%, 95% CI 6-11). An increased prevalence of COPD was associated with increasing age, smoking and biomass smoke exposure. The pooled odds ratio for the effect of current smoking (vs. never smoked) on COPD was 2.20 (95% CI 1.62-2.99).CONCLUSION: COPD causes morbidity and mortality in adults in SSA. Smoking is an important risk factor for COPD in SSA, and this exposure needs to be reduced through the combined efforts of clinicians, researchers and policymakers to address this debilitating and preventable lung disease.

Understanding Pre-Exposure Prophylaxis Adherence in Young Women in Kenya

OBJECTIVE

To present detailed analyses of long-term pre-exposure prophylaxis (PrEP) use and associated behaviors and perceptions among young Kenyan women.

DESIGN

Prospective, observational cohort.

METHODS

The Monitoring PrEP among Young Adult women Study involved 18 to 24-year-old women at high HIV risk initiating PrEP in Kisumu and Thika, Kenya. Visits for PrEP counseling and dispensing, HIV testing, and socio-behavioral data collection occurred at Month 1 and quarterly for 2 years. PrEP adherence was measured with pharmacy refill and real-time electronic monitoring, plus tenofovir diphosphate levels in 15% of participants. HIV risk behavior and perception were assessed by self-report in weekly short message service surveys from Months 6-24. Predictors of adherence were assessed with multivariable logistic regression analysis.

RESULTS

Three hundred forty-eight women (median age 21, VOICE risk score 7) were followed for 617 person-years. Pharmacy refills steadily declined from 100% (Month 0-1) to 54% (Months 22-24). Average electronically monitored adherence similarly declined from 65% (Month 0-1) to 15% (Months 22-24). Electronically monitored adherence had moderately high concordance with tenofovir diphosphate levels (67%). High average adherence (5+ doses/week) was seen at 385/1898 (20%) participant-visits and associated with low baseline VOICE risk score, >1 current sexual partner, ≤1-hour travel time to clinic, and the Kisumu site. short message service-reported behavior and risk perception were not associated with adherence. Four women acquired HIV (incidence 0.7/100 person-years).

CONCLUSIONS

PrEP adherence was modest and declined over time. HIV risk was inconsistently associated with adherence; clinic access and site-level factors were also relevant. Relatively low HIV incidence suggests participants may have achieved protection through multiple strategies.

The benefits of virtual learning webinars to both low and high-income countries

The 2019 Covid pandemic has brought about many changes in the relationships between high income countries (HICs) and partner organisations in low or low-middle income countries (LMICs), such as predominate in sub-Saharan Africa. Medicine, surgery and in particular urology is no exception to the changes that Covid-19 has demanded. Urolink represents the British Association of Urological Surgeons (BAUS) on the global urology stage and has been deleteriously impacted by the pandemic. Education, one of the pillars of Urolink's founding philosophies, has conventionally been delivered by face-to face (F2F) teaching, training or mentoring by UK urologists at their host's site outside of the United Kingdom (UK). As a consequence of the inability to travel due to the pandemic, BAUS Urolink has evolved a virtual online webinar package evolved by, and delivered between, urologists in Lusaka, Zambia, and various centres in the United Kingdom. The aim was to deliver curricular-based educational topics to trainees in both countries. This programme has generated a number of live webinars, and archived recordings, during the pandemic that has proven accessible, and educationally acceptable, to trainees in the UK and Zambia. This webinar series has also generated relationships between young urologists on different continents, given each a different view of healthcare delivery outside of their country of origin at no appreciable cost, and would appear to be an educational mechanism that is durable for, and applicable to, a wider participation in the post-pandemic world.

Incidence and correlates of high blood pressure from childhood to adulthood: the Birth to Twenty study

BACKGROUND

There is growing evidence from high-income countries suggesting that hypertension developed in childhood and adolescence persists into adulthood. The objective of this study was to investigate the incidence and risk factors of high blood pressure (BP) in urban black children.

METHODS

We used data from the Birth to Twenty (BT20+) cohort in Johannesburg, South Africa constituting of children born in 1990 and who had their growth, development and blood pressure measured at six follow-up periods over the course of 13 years. High BP was classified as at least 95th percentile for age, sex and height. Incidence rate of high BP was calculated using survival analysis and risk factors were determined by use of Cox proportional hazard regression.

RESULTS

Over a follow-up period of 13 years, the overall incidence rate of high BP was 57 cases per 1000 person-years (95% CI 53.2-61.1). Risk for incident high BP increased with rapid relative weight gain in early childhood (hazard ratio =1.11, 95% CI 1.00-1.22), mid-childhood (hazard ratio = 1.13, 95% CI 1.03-1.24) and adolescence (hazard ratio = 1.21, 95% CI 0.99-1.47). Maternal parity significantly increased the risk for incident high BP (hazard ratio = 1.08, 95% CI 1.01-1.15).

CONCLUSION

Maternal parity and relative weight gain were determinants for incident high blood pressure in urban black South African children and adolescents. To reduce the high incidence and the disease burden of high BP, national programs should focus on promoting healthy lifestyle in early stages of life to prevent rapid weight gain and later cardiovascular disease risk. Further research is required to investigate whether incident high BP in childhood predict clinical outcomes in adulthood.

Reaching for the 'first 95': a cross-country analysis of HIV self-testing in nine countries in sub-Saharan Africa

OBJECTIVES

HIV self-testing (HIVST) offers a promising approach to increase HIV diagnosis and advance progress towards the UNAIDS 95-95-95 targets. We aimed to understand patterns of HIVST awareness and utilization in nine sub-Saharan African (SSA) countries, with the goal of identifying populations to target in disseminating this technology.

DESIGN

A cross-sectional study.

METHODS

We pooled individual-level population-based data from nine Demographic and Health Surveys (DHS) in SSA conducted 2015-2019 (Burundi, Cameroon, Guinea, Malawi, Senegal, Sierra Leone, South Africa, Zambia, Zimbabwe). Primary outcomes were HIVST awareness and utilization. We used logistic regression with survey fixed effects to explore the relationship between sociodemographic characteristics and these outcomes. Models were adjusted for sex, age, rural/urban residence, education, wealth, and marital status. We accounted for complex survey design.

RESULTS

The study sample included 177 572 people (66.0% women, mean age 29 ± 10 years), of whom 86.6% [95% confidence interval (95% CI) 86.4-86.7] were unaware of HIVST, 11.7% (95% CI 11.6-11.9) were aware of but never used HIVST, and 1.7% (95% CI 1.6-1.8) had used HIVST. In adjusted models, women were less likely to be aware of HIVST [odds ratio (OR) 0.75, 95% CI 0.71-0.79], but more likely to have used HIVST (OR 1.17, 95% CI 1.03-1.32) compared with men. Rural residents, those who were least educated, and poorest were less likely to have heard of or used HIVST.

CONCLUSION

HIVST awareness and uptake were low. Rural, less educated, and lower income populations were least likely to have heard of or used HIVST. Efforts to scale-up HIVST in these settings should aim to reach these less advantaged groups.
