The Malaysia DREEM: perceptions of medical students about the learning environment in a medical school in Malaysia.

Background: Students' perceptions of their learning environment, by defining its strengths and weaknesses, are important for continuous improvement of the educational environments and curriculum. Therefore, the aim of this study was to explore students' perceptions of their learning environment, among medical students in Malaysia. Various aspects of the education environment were compared between year levels and sex.

Relationship between hypertension, diabetes and proteinuria in rural and urban households in Yemen.

Little information is available on the meanings of proteinuria in low-resource settings. A population-based, cross-sectional survey was performed in Yemen on 10 242 subjects aged 15-69 years, stratified by age, gender and urban/rural residency. Hypertension is defined as systolic blood pressure (BP) of 140 mm Hg and/or diastolic BP of 90 mm Hg, and/or self-reported use of antihypertensive drugs; diabetes is diagnosed as fasting glucose of 126 mg dl(-1) or self-reported use of hypoglycaemic medications; proteinuria is defined as +1 at dipstick urinalysis.

Epidemiology of hypertension in Yemen: effects of urbanization and geographical area.

Although globalization can contribute to increased blood pressure by spreading unhealthy behaviors, it also provides powerful means to tackle hypertension. The dissemination of information about and advice on cardiovascular prevention and facilitated contact with health services are valuable resources. To investigate the effects of urbanization, geographical area, and air temperature on hypertension burden and kidney damage, a survey was performed in 2008 with a door-to-door approach among urban and rural adult dwellers of three geographic areas (capital, inland, coast) of Yemen.

Impact of one or two visits strategy on hypertension burden estimation in HYDY, a population-based cross-sectional study: implications for healthcare resource allocation decision making.

Context: The prevalence of hypertension in developing countries is coming closer to values found in developed countries. However, surveys usually rely on readings taken at a single visit, the option to implement the diagnosis on readings taken at multiple visits, being limited by costs.

Objective: To estimate more accurately the magnitude and extent of the resource that should be allocated to the prevention of hypertension.
