Meta-analysis of published studies or meta-analysis of individual data? Caesarean section in HIV-positive women as a study case
Very few comparative evaluations of meta-analysis of published data and meta-analysis using individual patient data have appeared in the medical literature. The association between type of delivery and HIV perinatal...
The magnitude of loss to follow-up of HIV-exposed infants along the prevention of mother-to-child HIV transmission continuum of care: A systematic review and meta-analysis
INTRODUCTION: Although prevention of mother-to-child HIV transmission (PMTCT) programs are widely implemented, many children do not benefit from them because of loss to follow-up (LTFU). We conducted a systematic review...
Effects of postnatal interventions for the reduction of vertical HIV transmission on infant growth and non-HIV infections: A systematic review
INTRODUCTION: Guidelines in resource-poor settings have progressively included interventions to reduce postnatal HIV transmission through breast milk. In addition to HIV-free survival, infant growth and non-HIV infections should be considered....
Population-based biomedical sexually transmitted infection control interventions for reducing HIV infection
BACKGROUND: The transmission of sexually transmitted infections (STIs) is closely related to the sexual transmission of human immunodeficiency virus (HIV). Similar risk behaviours, such as frequent unprotected intercourse with different...
A systematic review of the quality of trials evaluating biomedical HIV prevention interventions shows that many lack power
Purpose: Several randomized, controlled trials (RCTs) have tested strategies to prevent sexual acquisition of HIV infection, but their quality has been variable. We aimed to identify, describe, and evaluate the...
Improving the prevention, diagnosis and treatment of TB among people living with HIV: The role of operational research
Operational research is necessary to improve the access to and delivery of tuberculosis prevention, diagnosis and treatment interventions for people living with HIV. We conducted an extensive review of the...
Randomized controlled trials of individual-level, population-level, and multilevel interventions for preventing sexually transmitted infections: What has worked?
BACKGROUND: Previous reviews of interventions to prevent sexually transmitted infections (STIs) focused mostly on human immunodeficiency virus (HIV) infection. We reviewed trials of interventions to prevent sexual transmission of any...
HIV-related stigma as a barrier to achievement of global PMTCT and maternal health goals: A review of the evidence
The global community has set goals of virtual elimination of new child HIV infections and 50 percent reduction in HIV-related maternal mortality by the year 2015. Although much progress has...
Analytic review of modeling studies of ARV Based PrEP interventions reveals strong influence of drug-resistance assumptions on the population-level effectiveness
BACKGROUND: Four clinical trials have shown that oral and topical pre-exposure prophylaxis (PrEP) based on tenofovir may be effective in preventing HIV transmission. The expected reduction in HIV transmission and...
