Preventive chemotherapy with praziquantel (PZQ) is the cornerstone of schistosomiasis control. However, a single dose of PZQ (40 mg/kg) does not cure all infections. Repeated doses of PZQ at short intervals might increase efficacy in terms of cure rate (CR) and intensity reduction rate (IRR). Here, ...we determined the efficacy of a single versus four repeated treatments with PZQ on Schistosoma mansoni infection in school-aged children from Côte d'Ivoire, using two different diagnostic tests.

Yaws is a non-venereal endemic treponemal infection caused by Treponema pallidum sub-species pertenue, a bacterium closely related to Treponema pallidum ssp. pallidum, the agent of venereal syphilis. Yaws predominantly affects children living in tropical regions of the world. It causes lesions of th...e skin, mucous membranes and bones which, without treatment, can become chronic and destructive. There is no widely available test to distinguish yaws from syphilis. Thus, migration of people from yaws-endemic areas to developed countries may present clinicians with diagnostic dilemmas. The other endemic treponemal infections are bejel (endemic syphilis) caused by Treponema pallidum ssp. endemicum and pinta caused by Treponema carateum.

Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteristics, aetiologies, treatment, economic burden and ...outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.

Considérations pour l’assouplissement des mesures sociale et de sante publique (MSSP), y compris le verrouillage dans les États membres de l’Union Afrique
En réponse aux premiers cas de maladie à coronavirus 2019 (COVID-19) signalés sur le continent, de nombreux États membres de l'Union a...fricaine ont rapidement mis en œuvre des mesures sanitaires et sociales (PHSM) à grande échelle. Ces mesures visaient à réduire la transmission et le nombre de nouveaux cas signalés, à protéger les populations les plus vulnérables et à laisser aux pays le temps de mettre en place des services de soins de santé et de diagnostic essentiels. Si ces actions rapides ont permis aux États membres de gagner du temps, les répercussions socio-économiques négatives se font largement sentir, et les pays étudient actuellement la meilleure façon d'assouplir ces mesures tout en continuant à gérer l'épidémie.

HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti...ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

Background: In the “Centre National Hospitalier de Pneumo-Phtisiologie” of Cotonou, Benin, little is known about
the characteristics of patients who have not attended their scheduled appointment, the results of tracing and the
possible b...enefits on improving treatment outcomes. This study aimed to determine the contribution of tracing
activities for those who missed scheduled appointments towards a successful treatment outcome.
Methods: A retrospective cohort study was carried out among all smear-positive pulmonary tuberculosis patients
treated between January and September 2013. Data on demographic and diagnostic characteristics and treatment
outcomes were accessed from tuberculosis registers and treatment cards. Information on those who missed their
scheduled appointments was collected from the tracing tuberculosis register. A univariate analysis was performed
to explore factors associated with missing a scheduled appointment
