Luminex single antigen bead (SAB) assays used to detect HLA antibodies may artificially increase sensitisation in highly sensitised patients (HSP). The presence of denatured HLA (dHLA) within the assay enables antibodies specific to cryptic HLA epitopes to bind, such antibodies are not clinically relevant. We sought to exclude dHLA reactivity in a cohort of very HSP, calculated reaction frequency (cRF) 95%-100% and determine the effect upon sensitisation.

The objective of this study was to determine gastrointestinal transit time in first-year health science students with a laboratory practical exercise conducted in two cohorts (classes of 2018 and 2019) of first-year health sciences students at the Health Science Campus in Windhoek, Namibia. All first-year health science students undertaking the Physiology course were invited to take part in the laboratory exercise. The primary outcome was the measurement of gastrointestinal transit time from the amount of time taken for ingested whole-kernel sweetcorn to be eliminated, which was calculated as the time period between ingestion of corn and the time of corn first seen in the stool and the time corn was last seen in the stool.

: The advent of antiretroviral therapy (ART) and early diagnosis of the human immunodeficiency virus (HIV) has resulted in an appreciable reduction in morbidity and mortality among people infected with HIV. However, tenofovir disoproxil fumarate (TDF)-containing ART regimens are associated with a reduction in creatinine clearance (CrCl). No evaluation has been conducted in Namibia to date on the relationship between TDF-containing ART and CrCl among patients with moderate to severe reductions in CrCl to guide future practice.

Training health-care students in settings with high-prevalence HIV and tuberculosis (TB) presents a challenge to reduce the risk of infection during their clinical training while maintaining quality education. We sought to gauge the risk of exposure to HIV and TB and identify associated variables through two cross-sectional surveys of health students at the University of Namibia. In the HIV exposure survey, overall almost one-quarter of students ( = 367) reported exposure to HIV-most often needle-stick injury-with a much higher rate reported in senior years (73% in year 6).
