Randomized Controlled Trial
Characteristics and drinking behaviour of patients on antiretroviral therapy who drink and attend HIV clinics in Tshwane, South Africa: Implications for intervention.
Patients on antiretroviral therapy (ART) who drink alcohol are at risk of poor medication adherence and negative health outcomes. ⋯ The high volume of alcohol consumed per occasion by patients on ART, especially beer and spirits drinkers, is a concern. Interventions that address structural drivers of heavy drinking and target HIV patients at risk of heavy drinking are needed.

Vitamin D deficiency (VDD) in pregnant women has been associated with adverse pregnancy and neonatal outcomes. 25-hydroxyvitamin D (25(OH)D) levels are affected by numerous factors, including vitamin D intake, skin pigmentation, latitude and season of the year; they therefore vary by race and country. Vitamin D status in pregnant women and their offspring in South Africa (SA) is not well established. ⋯ Among black SA women delivering in Johannesburg, about one in six mothers and one in three neonates have 25(OH)D levels indicative of VDD. Maternal HIV status appears not to affect levels of 25(OH)D in either the mother or her neonate. Research on the effects of VDD on the outcomes of pregnancy and the best methods to combat the high prevalence of VDD in women of childbearing age in the SA context is required.

When critically ill patients with life-threatening conditions need urgent, expensive, life-sustaining care, admission and triage decision-making may be extremely challenging as critical care practitioners strive to balance these high-stakes, high-stress, time-sensitive decisions against a limited resource. The factors affecting the decision to admit or refuse a patient entry to an intensive care unit (ICU) have not been described in the South African (SA) context. ⋯ A better understanding of factors affecting ICU admission/refusal decisions will allow for a more effective and appropriate referral process and more rational utilisation of scarce ICU resources. Further prospective studies are necessary to elucidate fully the impact of various other factors.

Amiloride is an antagonist of the renal tubular epithelial sodium channel (ENaC). As such, it is a diuretic that is both potassium and magnesium sparing. It is used for the treatment of potassium depletion and hypertension, and is the specific therapy for hypertension due to overactivity of the ENaC (Liddle syndrome and several additional genetic causes of the Liddle phenotype - low renin and low aldosterone). ⋯ The former is likely to result in a significant reduction in cardiovascular, stroke and kidney morbidity and mortality, because of improved BP control. Amiloride is very unlikely to ever be registered in SA, as it was first developed >50 years ago, and SAHPRA regulations prevent widespread prescription of this essential drug. This is a classic Gordian knot that requires a novel approach from authorities to sever the knot and improve the health of many South Africans.

Burnout is a response to prolonged stress and consists of three elements: emotional exhaustion (EE), depersonalisation (DP), and feelings of personal accomplishment (PA). The existence of burnout in doctors is often not acknowledged but has major consequences for personal and professional life. Only limited research has been done on the prevalence of burnout among registrars in South Africa (SA). ⋯ The prevalence of burnout in this study was higher than that reported in the national and international literature. Levels of DP were extremely high and are worrying, as DP affects professionalism and engagement of doctors. In keeping with the literature, no associations were found between sociodemographic factors and burnout, suggesting that the cause of burnout should be sought in the work environment. Efforts to improve autonomy in the workplace, development opportunities and promoting peer collaboration are needed to prevent burnout.
