Expanded access to antiretroviral therapy (ART) offers opportunities to strengthen HIV prevention in resource-limited settings. We invited 27 ART programmes from urban settings in Africa, Asia and South America to participate ...
Temporal changes in programme outcomes among adult patients initiating antiretroviral therapy across South Africa, 2002-2007
Objective: Little is known about the temporal impact of the rapid scale-up of large antiretroviral therapy (ART) services on programme outcomes. We describe patient outcomes [mortality, loss-to-follow-up (LTFU) and retention] ...
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, ...
Evaluation of paradoxical TB-associated IRIS with the use of standardized case definitions for resource-limited settings
Objective: Standardized case definitions have recently been proposed by the International Network for the Study of HIV-associated immune reconstitution inflammatory syndrome (INSHI; [IRIS]) for use in resource-limited ...
Symptoms of depression and anxiety among a sample of South African patients living with HIV
Little systematic research has been conducted on the extent of psychiatric disorders among South African patients in general, and among patients living with HIV in particular. The present study reports on a survey conducted ...
