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 ...
The potential to transmit Mycobacterium tuberculosis at a South African tertiary teaching hospital.
OBJECTIVES: To assess the risk of nosocomial transmission by confirmed pulmonary tuberculosis (PTB) patients in a high TB/HIV incidence environment. METHODS: Between November 2006 and April 2007, we carried out a cross-sectional ...
Comparison of two active case-finding strategies for community-based diagnosis of symptomatic smear-positive tuberculosis and control of infectious tuberculosis in Harare, Zimbabwe (DETECTB): A cluster-randomised trial
Background Control of tuberculosis in settings with high HIV prevalence is a pressing public health priority. We tested two active case-finding strategies to target long periods of infectiousness before diagnosis, which ...

Rapid on-site evaluation of transbronchial aspirates: Randomised comparison of two methods
The value of different staining methods for rapid analysis of transbronchial needle aspirates during bronchoscopy has not been explored. In the present study, we compared a Papanicolaou-based rapid stain, prepared by a ...
The S/Z ratio: A simple and reliable clinical method of evaluating laryngeal function in patients after intubation
Objectives: 1. To determine the consequences of prolonged intubation on laryngeal function.2. To evaluate simple clinical criteria or tests that could alert the clinician to potential laryngeal pathology requiring ear, ...
Symptoms of depression and anxiety among a sample of South African patients living with HIV

Characterization of HIV type 1 genetic diversity among South African participants enrolled in the AIDS Vaccine Integrated Project (AVIP) Study
The genetic diversity of HIV-1 strains circulating among HIV-1-infected South Africans was investigated in a cohort of 420 individuals enrolled as part of the AIDS Vaccine Integrated Project (AVIP) study. Representative ...
Time to detection of the growth of Mycobacterium tuberculosis in MGIT 960 for determining the early bactericidal activity of antituberculosis agentsTime to detection of the growth of Mycobacterium tuberculosis in MGIT 960 for determining the early bactericidal activity of antituberculosis agents
Evaluation of early bactericidal activity (EBA) by the determination of a fall in viable colony-forming units (CFU) of Mycobacterium tuberculosis in sputum is a first step in the clinical study of new antituberculosis ...
