Background: The global incidence of syphilis has increased in recent years. Understanding syphilis epidemiology will inform screening and treatment programs. However, such data are lacking in many communities.

The perioperative mortality rate has been suggested as a key quality metric to guide the expansion of care, but there is little information on how to risk-adjust this outcome measure.
Methods: We did a 42-month observational cohort study of surgical operations at a Ugandan secondary referral hospital.
Background: Non-communicable diseases (NCDs) represent a growing health burden in sub-Saharan Africa, especially in Uganda. The COVID-19 pandemic presented significant challenges for the Ugandan healthcare system, though changes in hospital admissions and outcomes for adults with NCDs and without COVID-19 infection remain unknown. We evaluated trends of NCD-related in-hospital mortality among patients without COVID-19 in a large regional referral hospital in Uganda from March 2019 through August 2021.

Background: Lenacapavir, a novel HIV-1 capsid inhibitor, shows promise for treating MDR HIV-1, as well as for pre-exposure prophylaxis (PrEP) in prevention of HIV infection. Its unique mechanism and lack of cross-resistance with other antiretroviral classes make lenacapavir a significant addition to HIV therapy. The clinical trials CALIBRATE and CAPELLA have demonstrated high viral suppression rates in both ART-naive individuals and individuals with MDR HIV-1.

Encrypted, closed group chats delivered via WhatsApp provided peer support and improved communication between adolescents with HIV, their caregivers, and healthcare providers. We randomized 80 South African adolescents ages 15 to 19 years with perinatally-acquired HIV to receive either the intervention (n=40) or standard of care (n=40).

Background: Initiation of ART among people living with HIV (PLWH) having a CD4 count ≤ 350cells/µl, produces poor immunological recovery, putting them at a high risk of opportunistic infections. To mitigate this, PLWH on ART in Uganda frequently use herbal remedies like Artemisia annua and Moringa oleifera, but their clinical benefits and potential antiretroviral (ARV) interactions remain unknown. This study examined the impact of A.

Real-time electronic adherence monitoring involves "smart" pill boxes that record and monitor openings as a proxy for pill taking and may be useful in understanding and supporting PrEP use; however, acceptability and/or feasibility for PrEP users is uncertain. We sought to understand the experiences of using a real-time electronic adherence monitor for PrEP delivery among young women in Kisumu and Thika, Kenya. We used the Wisepill device to monitor PrEP use among 18-24-year-old women for two years.

This study involved the development and pilot testing of My Way-a novel delivery system for PrEP and co-packaged sexual health services.
Methods: My Way was developed in Kisumu, Kenya through a user-centred design process (2020).
Timely initiation of and adherence to antiretroviral therapy (ART) is critical for improving HIV outcomes and reducing HIV transmissibility. Social networks, or the social relationships individuals have with each other, have been linked with positive health outcomes, but less is known about the extent to which social network composition and structure are associated with improved ART adherence among people living with HIV (PLWH). We conducted an ego-centric network study among 828 previously ART-naïve PLWH presenting for ART initiation at 11 clinics in Mbarara, Uganda (rural population) and Gugulethu, South Africa (peri-urban population).

Participants received real-time electronic adherence monitors and were randomized (1:1:1) to: (i) daily SMS (reminders to TB patients and notifications to social supporters sent daily for 3 months, then triggered by late or missed dosing for 3 months); (ii) weekly SMS (reminders to TB patients and notifications to social supporters sent weekly for 3 months, then triggered by late or missed dosing for 3 months); or (iii) control (no SMS). Feasibility was mainly verified by the technical function of the intervention at Month 6.

Yet, few studies have evaluated the combined effects of maternal HIV infection and alcohol use on birth outcomes. We analyzed data from a prospective cohort study of HIV-related placental changes in Ugandan women.

However, one third initiating first-line treatment experience virological failure and the determinants of HRQoL in this key population are unknown. Our study aims to identify determinants of among PWH failing antiretroviral treatment in sub-Saharan Africa.

The COVID-19 pandemic has highlighted disparities in outcomes by social determinants to health. It is unclear how much end-of-life discussions and a patient's decision about code status ("do not resuscitate," do not resuscitate, or "comfort measures only," [CMO] orders) might contribute to in hospital disparities in care, especially given know racial inequities in end-of-life care. Here, we looked at factors associated with code status orders at the end of hospitalization for patients with COVID-19.

We compared multiple adherence measures in a two-year study of young Kenyan women at high risk of HIV acquisition. Among 289 participants, concordance between electronic adherence monitoring (EAM) and tenofovir diphosphate (TFV-DP) in dried blood spots ranged from 57 to 72% depending on selected thresholds.

Background: Incomplete antiretroviral therapy (ART) adherence has been linked to deleterious immunologic, inflammatory, and clinical consequences, even among virally suppressed (<50 copies/mL) persons with human immunodeficiency virus (PWH). The impact of improving adherence in the risk of severe non-AIDS events (SNAEs) and death in this population is unknown.
Methods: We estimated the reduction in the risk of SNAEs or death resulting from an increase in ART adherence by (1) applying existing data on the association between adherence with high residual inflammation/coagulopathy in virally suppressed PWH, and (2) using a Cox proportional hazards model derived from changes in plasma interleukin 6 (IL-6) and D-dimer from 3 randomized clinical trials.
Identifying factors associated with alcohol use changes during pregnancy is important for developing interventions for people with HIV (PWH). Pregnant PWH (n = 202) initiating antiretroviral therapy in Uganda and South Africa completed two assessments, 6 months apart (T1, T2). Categories were derived based on AUDIT-C scores: "no use" (AUDIT-C = 0 at T1 and T2), "new use" (AUDIT-C = 0 at T1, >0 at T2), "quit" (AUDIT-C > 0 at T1, =0 at T2), and "continued use" (AUDIT-C > 0, T1 and T2).

Better understanding the drivers of these disparities is not only critical for COVID-19 care but also to ensure equitable treatment more generally. In this paper, we look at how hospital admission patterns, both to the medical ward and the intensive care unit (ICU), may have differed by race, ethnicity, and social determinants of health.

Methods: We analyzed secondary outcomes from the REVAMP clinical trial: a pragmatic, open label, parallel-arm randomized trial investigating resistance versus viral load testing for individuals failing first-line treatment in South Africa and Uganda. We collected resource data, valued according to local cost data and used the 3-level version of EQ-5D to measure HRQOL at baseline and 9 months.

Background: The burden of non-communicable diseases (NCDs) is high in Malawi. However, resources and training for NCD care remain scarce, especially in rural hospitals. Current care for NCDs in the developing world focuses on the WHO's traditional 4 × 4 set.

Electronic monitors provide detailed adherence information and can enable real-time interventions; however, their use to date has largely been confined to research. This pilot study (NCT03825952) sought to understand feasibility and acceptability a relatively low-cost version of this technology and associated interventions for routine ART delivery in sub-Saharan Africa.

Among 348 women, we selected a three-trajectory adherence model: low and declining (N = 211, 61%), moderate but declining (N = 119, 34%) and steady high adherers (N = 18, 5%). We also identified a two-trajectory HIV risk model based on self-perceived risk in the past week: high and increasing (N = 28, 8%) and steady low (N = 320, 92%) risk.

Of the 199 adolescents who transitioned to adult care, 84 (42%) had viral suppression (< 200 copies/ml) one year after transition. Adolescents on first-line ART, with documented HIV status disclosure, and higher rating on the HIV Adolescent Readiness to Transition Scale had significantly higher odds of viral suppression after transition.
