Promoting evidence-based health care in Africa

Charles Shey Wiysonge, Director ofCochane  South Africa, gave an interview to the World Health Organization Bulletin. Here is a re-post , with premission, from their  recent publication.Charles Shey Wiysonge is devoted to encouraging better use of scientific evidence for health policies and programmes in African countries. He is the director of the South African Cochrane Centre, a unit of the South African Medical Research Council, and a professor of epidemiology and biostatistics at the department of Global Health in the Faculty of Medicine and Health Sciences at Stellenbosch University in South Africa. He was Chief Research Officer at the Joint United Nations Programme on HIV/AIDS 2006 –2007 and a Medical Research Council Africa Fellow at the University of Cape Town (UCT) 2004–2006. In Cameroon, he worked for the National Ministry of Public Health 1998–2004. From 1995 to 1998, he was a physician at the University Teaching Hospital in Yaoundé, Cameroon. He is a member of sev eral editorial boards and joined the World Health Organization’s (WHO) Strategic Advisory Group of Experts on immunization in 2016. He graduated in medicine from the University of Yaoundé I in 1995, earned his Master’s degree in epidemiology from Cambridge University in the United Kingdom of Gr eat Britain and Northern Ireland and a Doctor of Philosophy in vaccinology from UCT. Q: How did you become interested in medicine and public health?A: Gro...

Authors: Bergland OU, Søraas CL, Larstorp ACK, Halvorsen LV, Hjørnholm U, Hoffman P, Høieggen A, Fadl Elmula FEM Abstract PURPOSE: The blood pressure (BP) lowering effect of renal sympathetic denervation (RDN) in treatment-resistant hypertension shows variation amongst the existing randomised studies. The long-term efficacy and safety of RDN require further investigation. For the first time, we report BP changes and safety up to 7 years after RDN, compared to drug adjustment in the randomised Oslo RDN study. MATERIALS AND METHODS: Patients with treatment-resistant hypertension, defined...

Authors: Zhang W, Xu JZ, Lu XH, Li H, Wang D, Wang JG Abstract PURPOSE: We hypothesise that dietary sodium intake interacts with serum uric acid to influence blood pressure (BP) in children and adolescents. In the present study, we investigated ambulatory BP in relation to hyperuricaemia, dietary sodium intake and their interaction in children and adolescents with hypertension. MATERIALS AND METHODS:  A total of 616 study participants were 10-24 years old and had primary hypertension diagnosed after admission in a specialised inpatient ward. Ambulatory BP monitoring was performed during hospitalisat...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

Authors: Saavedra J, Reyes JG, Salinas DG Abstract Cytosolic Ca2+ concentration ([Ca2+ ]) has an important role in spermatozoa and hence it regulates fertilization. In male germinal cells, there are indirect evidences that this ion could regulate physiological processes in spermatogenesis. Since little is known about Ca 2+ homeostasis in spermatogenic cells, in this work we propose a mathematical model that accounts for experimental [Ca2+ ] dynamics triggered by blockade of the SERCA transport ATPase with thapsigargin in round rat spermatids, without external Ca2+ and with different extracellular lactate concentrat...

Abstract In this work we present an assessment of mercury (Hg) and methyl mercury (MeHg) bioaccumulation in different species of marine sponges collected off the Northwestern Mediterranean and Northeastern Atlantic coasts. Overall the results showed significant accumulation of Hg in sponges, with the Mediterranean sponge Chondrilla nucula exhibiting the highest total Hg content (up to 0.5 mg kg-1) and bio-concentration factor (BCF) up to 23. A significant inter-species variability of Hg bioaccumulation was observed among species collected at the same site. The sponges, collected in marine environment con...
