Introduction: To ensure there is adequate investment into diagnostics, an understanding of the magnitude of impact and return on investment is necessary. We, therefore, sought to understand the health and economic impacts of the molecular diagnostic programme in South Africa, to deepen the understanding of the broad value of diagnostics and guide future healthcare investments.

Methods: We calculated the 10-year (where data were available) total cost and disability-adjusted life-years (DALYs) averted associated with molecular testing for tuberculosis diagnosis (2013-2022), HIV viral load monitoring (2013-2022), early infant diagnosis of HIV infection (2013-2022) and SARS-CoV-2 testing (2020-2022), based on the actual number of molecular tests conducted in South Africa for the respective time periods.

Objective: People living with HIV (PLHIV) are often recruited from primary healthcare clinics (PHC) into clinical trials. On trial completion, they are transferred back to the facility for continued care and support in managing their condition, potentially leading to better health outcomes. Because transferring PLHIV back to PHCs post-clinical trials may result in decreased access to specialised care or resources that were available during the trial, this study explored insights into challenges faced during reintegration from clinical trial settings into PHCs and antiretroviral therapy (ART) adherence post-clinical trials.

Article Synopsis
  • Weight gain is commonly seen after starting antiretroviral therapy, particularly among females, black individuals, and those with low initial CD4 counts, with some medications like tenofovir disoproxil fumarate and efavirenz showing less weight gain.
  • In a study combining data from three clinical trials, it was found that participants experienced weight gain over 96 weeks, particularly those with CD4 counts below 100, with significant predictors being lower CD4 counts, female sex, and certain medications.
  • The results suggest that those with low CD4 counts may experience substantial weight gain, potentially leading to obesity, indicating a need for tailored weight management strategies for these individuals.

Objective: The aim of the study is to identify suitable definitions and patient-reported outcome measures (PROMs) to assess each of the six core outcomes previously identified through the COMMA (Core Outcomes in Menopause) global consensus process relating to vasomotor symptoms: frequency, severity, distress/bother/interference, impact on sleep, satisfaction with treatment, and side effects.

Methods: A systematic review was conducted to identify relevant definitions for the outcome of side-effects and PROMs with acceptable measurement properties for the remaining five core outcomes. The consensus process, involving 36 participants from 16 countries, was conducted to review definitions and PROMs and make final recommendations for the measurement of each core outcome.

Background: Community healthcare worker (CHW) training programs are becoming increasingly comprehensive (an expanded range of diseases). However, the CHWs that the program relies on have limited training. Since CHWs' activities occur largely during household visits, which often go unsupervised and unassessed, long-term, ongoing assessment is needed to identify gaps in CHW competency, and improve any such gaps.

Weight stigma is a well-recognised public health issue affecting many members of society including women during the preconception period. The impacts of preconception weight stigma on women are significant and may result in decreased access to and uptake of healthcare, and mental health concerns. The consequences of this weight stigma may translate to negative maternal outcomes and even intergenerational effects on the child.

The health 'brain drain' (HBD) is an issue of significant global bioethical concern, resulting in severe maldistribution of healthcare workers (HCWs) and gross inequities in health service provision. The ethics of the HBD and its possible mitigation strategies are, however, complex and areas of active ongoing bioethical debate. South Africa faces a dire and worsening HBD crisis, and use a mitigation strategy of compulsory community service, or 'comserve', for most HCWs.

It has long been known that tissue non-specific alkaline phosphatase (TNAP) is essential for the correct formation of bone, as altered expression or function of this enzyme results in hypophosphatasia, a disease characterised by compromised bone structure, density and strength. However, recent evidence strongly suggests that the enzyme also has a role in lipid accrual and adipogenesis, a function that seems far removed from bone formation. Given that mesenchymal stromal cells (MSCs) are progenitors of both osteoblasts and adipocytes, the question arises of how TNAP is regulated to potentially have a different function when MSCs undergo either osteogenesis or adipogenesis.
