Screening for trisomy 21 provides pregnant women with accurate risk information. Different algorithms are used to screen for trisomy 21 in South Africa (SA). The Fetal Medicine Foundation (FMF) provides software to screen for trisomy 21 in the first trimester by ultrasound or a combination of ultrasound and biochemistry (combined screening), and requires regular and stringent quality control. With αlpha software, first trimester combined screening and screening with biochemistry alone in the first or second trimester are possible. The αlpha screening requires quality control of biochemical tests, but not of ultrasound measurements. Ideally, a screening test should have a high detection and a low screen positive rate. Despite the availability of these screening programmes, only a minority of infants with trisomy 21 are detected prenatally, raising questions about the effectiveness of screening. ⋯ Screening with FMF software has a similar screen positive rate and better detection rate than screening with αlpha software. The low prenatal detection rate of trisomy 21 is mainly due to a low prevalence of screening. More research is needed in the SA setting to explore why screening and confirmatory testing after high-risk results are not performed in many pregnancies.

Biliary atresia (BA) is an obstructive inflammatory disease of the bile ducts. Without intervention, the disease rapidly progresses to liver cirrhosis and fibrosis, with end-stage liver failure and death occurring within the first 3 years of life. It is the most common indication for liver transplantation (LT) in the paediatric population. The management of BA in South Africa (SA) faces multiple challenges, such as late referrals and socioeconomic burdens, with suboptimal outcomes. ⋯ Late presentation, cholangitis and cessation of bile flow after an initial successful KPE, and socioeconomic challenges are issues of concern and had a detrimental influence on the outcome of BA in our study population. Implementing screening measures and education programmes at the primary healthcare level is essential to diagnose and refer BA patients timeously. Establishing support systems to assist socioeconomically disadvantaged patients will enable them to qualify for LT.

Bronstein and Nyachowe recently argued that the conditions for the lawful processing of personal information, as provided in the Protection of Personal Information Act 4 of 2013 (POPIA), do not apply to health research in South Africa. This article critically analyses the authors' interpretation of section 3(2)(b) of POPIA and challenges two of its aspects.
