Evaluation of performance and acceptability of two rapid oral fluid tests for HIV detection in Mozambique

J. clin. microbiol; 52 (10), 2014
Simplified HIV testing based on oral fluid (OF) may allow the expansion of HIV infection counseling and testing (CT) while reducing the risk due to exposure to needles and blood collection. This study evaluated the performance and acceptability of two OF tests (the OraQuick Advance Rapid HIV-1/2 and the ...

Intermittent preventive treatment of malaria in pregnancy with mefloquine in HIV-negative women: a multicentre randomized controlled trial

PloS med; 11 (9), 2014
Background: Intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) is recommended by WHO to prevent malaria in African pregnant women. The spread of SP parasite resistance has raised concerns regarding long-term use for IPT. Mefloquine (MQ) is the most promising of avai...

PLos ONE; 9 (2), 2014
Background: Co-infection with falciparum malaria and HIV-1 increases the severity and mortality of both infections in unstable malaria-transmission areas. In contrast, in stable transmission areas, HIV co-infection increases the severity of both infections but has not been found to influence malaria mort...
