A randomized trial for combination nicotine replacement therapy for smoking cessation among people with HIV in a low-resourced setting.

Objective: The purpose of this study was to evaluate the efficacy of combination nicotine replacement therapy (c-NRT) for smoking cessation among people with HIV (PWH) in South Africa.

Design: We conducted an open label, individually randomized clinical trial.

Methods: Using a two-armed approach, PWH who smoke were randomized to receive either 1) intensive anti-smoking behavioral counseling (BC) or 2) intensive anti-smoking BC plus c-NRT (nicotine patches augmented by nicotine gum).

Evaluating the accuracy of planar gated blood pool processing software using simulated patient studies.

Planar gated blood pool (GBP-P) radionuclide imaging is a valuable non-invasive technique for assessing left ventricular ejection fraction (LVEF). Serial cardiac imaging can be performed to monitor the potential decline in LVEF among patients undergoing cardiotoxic chemotherapy. Consequently, accurate LVEF determination becomes paramount.

Comparison of QuantiFERON Gold In-Tube Versus Tuberculin Skin Tests on the Initiation of Tuberculosis Preventive Therapy Among Patients Newly Diagnosed With HIV in the North West Province of South Africa (the Teko Study): A Cluster Randomized Trial.

Background: Tuberculosis (TB) preventive therapy (TPT) reduces the risk of TB disease in people with human immunodeficiency virus (HIV), yet uptake has been suboptimal in many countries. We assessed whether QuantiFERON Gold In-Tube (QGIT) during routine HIV care increased TB infection (TBI) testing and TPT prescriptions.

Methods: This parallel-arm, 1:1 cluster-randomized controlled trial compared the standard-of-care tuberculin skin test to QGIT in South Africa.

Intracranial meningiomas at a tertiary hospital: Spectrum of MRI findings with histopathologic correlation.

Background: Intracranial meningiomas consist of a heterogenous group of histological subtypes, some of which are rare. Data that may play an important role in neurosurgical decision-making regarding the incidence and MRI features of these histological subtypes in the South African population groups, are lacking.

Objectives: This study aimed to assess the spectrum of MRI findings and histological subtypes of meningiomas in the South African context, with the goal of improving the paucity of literature on the topic.

Assessing potential drug-drug interactions between clofazimine and other frequently used agents to treat drug-resistant tuberculosis.

Clofazimine is included in drug regimens to treat rifampicin/drug-resistant tuberculosis (DR-TB), but there is little information about its interaction with other drugs in DR-TB regimens. We evaluated the pharmacokinetic interaction between clofazimine and isoniazid, linezolid, levofloxacin, and cycloserine, dosed as terizidone. Newly diagnosed adults with DR-TB at Klerksdorp/Tshepong Hospital, South Africa, were started on the then-standard treatment with clofazimine temporarily excluded for the initial 2 weeks.

Optimizing PSMA scintigraphy for resource limited settings - a retrospective comparative study.

Background: PSMA PET/CT is the most sensitive molecular imaging modality for prostate cancer (PCa), yet much of the developing world has little or no access to PET/CT. [Tc]Tc-PSMA scintigraphy (PS) is a cheaper and more accessible gamma camera-based alternative. However, many resource-constrained departments have only a single camera without tomographic or hybrid imaging functionality, and camera time is frequently in high demand.

Surgical training and capacity development in the South African internship programme.

Medical practitioners in South Africa manage a quadruple burden of disease. Junior doctors, who contribute significantly to the health workforce, must complete 2 years of internship training and 1 year of community service work in state health facilities after graduation to register as an independent medical practitioner. The aim of this article is to give a critical appraisal of the current national internship programme and why it was implemented, and outline suggestions for future changes.

Trans-anal small bowel evisceration in a patient with a perforated rectal prolapse.

An 85-year-old lady with a history of chronic constipation presented with gangrenous small bowel protruding from the anus through a hole in a prolapsed rectum. At surgery, a resection of 125 cm of gangrenous small bowel was performed in the perineum prior to laparotomy, where rectal repair was followed by the creation of a sigmoid loop colostomy and double-barrel ileostomy. This avoided an intrabdominal anastomosis which was felt likely to complicate due to the lady's intraoperative haemodynamic instability requiring inotropic support.

A cross-sectional study of attitudes and behaviors of snuff use and cessation among people with and without HIV in South Africa.

Background: Despite a high (48%) prevalence of snuff use among women with HIV in South Africa, little is known of the attitudes and behaviors of use, strategies for cessation, and potential health risks.

Methods: In a cross-sectional study, a questionnaire was administered to adults (≥18 years) with (HIV+) and without HIV (HIV-) who self-reported current snuff use to collect information on demographics, snuff use and cessation attempts, preferred strategies for cessation, other substance use, history of respiratory illness, and mental health.

Results: 150 (74 HIV+, 76 HIV-) participants were enrolled; 115 (77%) were daily snuff users, 6 (4%) were current smokers, and 17 (11%) former smokers.

The attributable fraction of respiratory syncytial virus among patients of different ages with influenza-like illness and severe acute respiratory illness in a high HIV prevalence setting, South Africa, 2012-2016.

Objectives: The detection of respiratory syncytial virus (RSV) in upper airway samples does not necessarily infer causality of illness. We aimed to calculate the attributable fraction (AF) of RSV in clinical syndromes across age groups.

Methods: Using unconditional logistic regression models, we estimated the AF of RSV-associated influenza-like illness (ILI) and severe acute respiratory illness (SARI) cases by comparing RSV detection prevalence among ILI and SARI cases to those of healthy controls in South Africa, 2012-2016.

Medicine and the Law.

The South African (SA) medical internship training programme model was recently revised to extend training into the primary care platform. In this article, we reflect on the experiences of training under the new model from an intern perspective. We use these reflections to make recommendations to the Health Professions Council of SA on how to further improve the training model by implementing systems that guide and empower the intern doctor practising at a primary level of care.

Effect of HIV on mortality among hospitalised patients in South Africa.

Background: HIV and AIDS continues to impose substantial healthcare challenges in sub-Saharan Africa, but there are limited local data comparing inpatient outcomes between people with HIV (PLWH) and those uninfected.

Objectives: To compare cause-specific mortality among hospitalised adolescents and adults, stratified by HIV-serostatus.

Method: A cross-sectional analysis was performed, analysing cause-specific inpatient mortality data and total admissions, from 01 January 2017 to 30 June 2020, at Tshepong Hospital, North West province, South Africa.

The economic burden of RSV-associated illness in children aged < 5 years, South Africa 2011-2016.

Background: Data on the economic burden of RSV-associated illness will inform decisions on the programmatic implementation of maternal vaccines and monoclonal antibodies. We estimated the cost of RSV-associated illness in fine age bands to allow more accurate cost-effectiveness models to account for a limited duration of protection conferred by short- or long-acting interventions.

Methods: We conducted a costing study at sentinel sites across South Africa to estimate out-of-pocket and indirect costs for RSV-associated mild and severe illness.

Undiagnosed Pulmonary Tuberculosis (TB) and Coronavirus Disease 2019 (COVID-19) in Adults Dying at Home in a High-TB-Burden Setting, Before and During Pandemic COVID-19: An Autopsy Study.

Background: Missing or undiagnosed patients with tuberculosis (TB) or coronavirus disease 2019 (COVID-19) are of concern. Identifying both infections in patients with no diagnosis prior to death contributes to understanding the burden of disease. To confirm reports of global reduction in TB incidence, a 2012 autopsy study of adults dying at home of natural causes in a high-TB-burden setting was repeated, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) assessments after the first COVID-19 surge in South Africa.

The burden of RSV-associated illness in children aged < 5 years, South Africa, 2011 to 2016.

Background: Vaccines and monoclonal antibodies to protect the very young infant against the respiratory syncytial virus (RSV)-associated illness are effective for limited time periods. We aimed to estimate age-specific burden to guide implementation strategies and cost-effectiveness analyses.

Methods: We combined case-based surveillance and ecological data to generate a national estimate of the burden of RSV-associated acute respiratory illness (ARI) and severe acute respiratory illness (SARI) in South African children aged < 5 years (2011-2016), including adjustment for attributable fraction.

Healthcare Resource Utilization in Controlled Versus Uncontrolled Adults Living With Type 1 Diabetes in the South African Public Healthcare Sector.

Objectives: This study aimed to understand the cost implications of managing people living with type 1 diabetes mellitus in the South African public healthcare system.

Methods: A multicenter, noninterventional retrospective chart review study was performed. Data on healthcare resource consumption, demographics, risk factors, clinical history, and acute events were collected.

A Cross-Sectional Analysis of the Nicotine Metabolite Ratio and Its Association with Sociodemographic and Smoking Characteristics among People with HIV Who Smoke in South Africa.

The nicotine metabolite ratio (NMR) is associated with race/ethnicity but has not been evaluated among smokers in the African region. We conducted a cross-sectional analysis of baseline data from a large randomized, controlled trial for smoking cessation among people with HIV (PWH) in South Africa. Urine samples were analyzed for the NMR and evaluated as a binary variable using a cutoff value of the fourth quartile to determine the fastest metabolizers.

Health Care Resource Utilization in Adults Living With Type 1 Diabetes Mellitus in the South African Public Health Sector: Protocol for a 1-Year Retrospective Analysis With a 5-, 10-, and 25-Year Projection.

Background: Type 1 diabetes mellitus (T1DM) is less common than type 2 diabetes mellitus but is increasing in frequency in South Africa. It tends to affect younger individuals, and upon diagnosis, exogenous insulin is essential for survival. In South Africa, the health care system is divided into private and public health care systems.

Risk Factors for Severe Coronavirus Disease 2019 Among Human Immunodeficiency Virus-Infected and -Uninfected Individuals in South Africa, April 2020-March 2022: Data From Sentinel Surveillance.

Background: Data on risk factors for coronavirus disease 2019 (COVID-19)-associated hospitalization and mortality in high human immunodeficiency virus (HIV) prevalence settings are limited.

Methods: Using existing syndromic surveillance programs for influenza-like-illness and severe respiratory illness at sentinel sites in South Africa, we identified factors associated with COVID-19 hospitalization and mortality.

Results: From April 2020 through March 2022, severe acute respiratory syndrome coronavirus 2 was detected in 24.

Coronavirus Host Genomics Study: South Africa (COVIGen-SA).

Host genetic factors are known to modify the susceptibility, severity, and outcomes of COVID-19 and vary across populations. However, continental Africans are yet to be adequately represented in such studies despite the importance of genetic factors in understanding Africa's response to the pandemic. We describe the development of a research resource for coronavirus host genomics studies in South Africa known as COVIGen-SA-a multicollaborator strategic partnership designed to provide harmonised demographic, clinical, and genetic information specific to Black South Africans with COVID-19.
