Advances in DNA sequencing technologies and computational tools over the past few years have led to vast improvements in the metagenomic analysis of the human microbiota. While this has also significantly improved our understanding of the role of the host-microbiome interaction in health and disease, the current clinical expectation is that testing, particularly of the gastrointestinal biome, can be used to diagnose, manage and treat patients. The authors outline the available technologies and highlight current limitations of these techniques to address this clinical demand. Through understanding the limitations of and need for more research and data collection, one can improve the appropriate utilisation and interpretation, as well as the current rational clinical application of these techniques.

Delays to surgery for acute appendicitis in low- and middle-income countries lead to significant morbidity. ⋯ Delays to surgery beyond 72 hours significantly increased complicated appendicitis, an important risk factor for SSI. Access to facilities with surgical capability and the use of laparoscopic surgery are modifiable risk factors for SSI.

Large cohorts of HIV-1 perinatally infected children with long-term follow-up in developing countries are limited. ⋯ We observed high rates of virological failure and emergence of HIV drug resistance mutations. Despite gains made by SA in the treatment of HIV, such results challenge the country's ability to meet global targets of 90% viral suppression by 2020.

Extracorporeal life support is the utilisation of advanced techniques to sustain circulatory and/or ventilatory functions in critically ill patients when standard therapies fail. It is well established in developed countries. There is increasing literature supporting its application in refractory cardiac arrest with a potential reversible cause, a procedure also known as extracorporeal cardiopulmonary resuscitation (eCPR). ⋯ In both these cases the cardiac arrest was witnessed, occurred in the emergency department, and failed to respond to standard advanced resuscitative measures. Both the patients were discharged neurologically intact. Although it is effective, the benefit of this advanced method of resuscitation in a low- to middle-income country is debated.

An increasing number of girls living with perinatally acquired HIV (PHIV) are reaching adolescence and adulthood and becoming pregnant. Youth living with PHIV (YLPHIV) may have HIV-associated infections/complications, long-term exposure to antiretroviral treatment (ART), drug resistance and increased psychosocial challenges, which may adversely affect pregnancy outcomes. There is a lack of published studies on pregnancy in YLPHIV in sub-Saharan Africa. Objectives. To describe characteristics of pregnant South African (SA) YLPHIV and their pregnancy outcomes. ⋯ In recent years, the number of pregnancies in YLPHIV has increased. A considerable proportion of pregnancies occurred in YLPHIV ≤16 years old. A high proportion of pregnancies was electively terminated. The prevalence of elevated VL and poor immunological status among pregnant YLPHIV is concerning.
