Abstract Background We aimed to assess the prevalence of Salmonella Typhi through DNA and IgM-antibody detection methods as a prelude to extended surveillance activities at sites in Ghana, Madagascar, and Ethiopia. Methods We performed species-specific real-time polymerase reaction (RT-PCR) to identify bacterial nucleic acid, and enzyme-linked immunosorbent assay (ELISA) for detecting HlyE/STY1498-, CdtB/STY1886-, pilL/STY4539- and Vi-antigens in blood and biopsy specimens of febrile and non-febrile subjects. We generated antigen-specific ELISA proxy cut-offs by change-point analyses,...

Effectiveness of school-based interventions for preventing tobacco smoking initiation among young people in low- and middle-income countries: a systematic review protocol
Divine Darlington Logo, Yeetey Enuameh, George Adjei, Arti Singh, Emmanuel Nakua, Edward Dassah, Felix Boakye Oppong & Ellis Owusu-Dabo
Abstract Background Despite the commendable progress made globally in tobacco control, the world is falling short of achieving a 30% relative reduction in current tobacco use by 2025. The African region remains the least in the efforts in fighting the tobacco epidemic and is most exploited by the tobacco industry. Schools have been continuously used for over three decades as a setting for delivering youth smoking prevention programmes; however, the evidence of the effectiveness of...
