Evaluating the BED capture enzyme immunoassay to estimate HIV incidence among adults in three countries in sub-Saharan Africa
Serological assays for estimating HIV-1 incidence are prone to misclassification, limiting the accuracy of the incidence estimate. Adjustment factors have been developed and recommended for estimating assay-based HIV-1 ...
Can a cumulus cell complex be used to select spermatozoa for assisted reproduction?
Since the onset of intracytoplasmic sperm injection, researchers have intensified the search for the ideal spermatozoa to be used for injection. The aim of this study was to record the functional role of cumulus cell ...

Management of life-threatening haemoptysis in an area of high tuberculosis incidence
BACKGROUND: Emergency admissions with life-threatening haemoptysis in an area of high tuberculosis (TB) incidence at the University of Stellenbosch and Tygerberg Academic Hospital, South Africa. It is unclear if lung ...
Risk factors for recurrence of haemoptysis following bronchial artery embolisation for life-threatening haemoptysis
SETTING: Life-threatening haemoptysis is a frequent and often fatal complication in areas with a high prevalence of tuberculosis (TB). Bronchial artery embolisation remains the standard initial treatment. Subsequent curative ...
Cytokine production in patients with tuberculous pericarditis
SETTING: An academic hospital in the Western Cape, South Africa. OBJECTIVE: To evaluate cytokine production (interferon-gamma [IFN-γ], interleukin-1 [IL-1], interleukin-2 [IL-2], interleukin-6 [IL-6], interleukin-10 [IL-10], ...
