Filter by:Primary purpose of the study: to describe sexual behavior of Prep users, whatever mode of intake, ie continuous or on-demand; it has been shown in some studies, an increase of sexual risks in Prep users, and therefore an similar increase of STIs (sexually transmitted diseases); using a self-questionnaire, we'd like to evaluate sexual behavior before, and 6 months after, starting Prep. Secondary purposes: to describe medical characteristics of Prep users (past medical condition, demographic characteristics, vaccinations, kidney function, serological results, urine and anal/pharyngeal swabs), clinical and biological Prep safety, STIs occurrence, and antibiotic prescriptions, continuous or on-demand intake, Prep indication.
Although coverage for primary childhood immunizations has improved, a significant proportion of young children and pregnant women living in low-resource settings remain inadequately immunized. While young children receive some primary vaccines, many are never fully vaccinated. Progressive decline in immunizations are in large part attributable to poor follow-up and compliance. Major challenges include maintaining immunization records linked to positive identification of the individual child, incentivizing follow-up and return immunizations and efficiently identifying and targeting non-compliant subjects. Mobile-phone costs have decreased dramatically in the developing world with rapid proliferation of web and mobile-phone connectivity. Novel approaches that integrate these modern technologies with existing resources in low and middle income countries can cost-effectively address these challenges. In this proposal, investigators will evaluate a novel software platform, utilizing biometric identification and of subjects, paired with intelligent and subject-aware, mobile-phone reminders and compliance-linked incentives to improve uptake and coverage of primary vaccinations in young children.
