BACKGROUND Maternal mortality in South Africa is rising, and heart conditions currently account for 41 per cent of indirect causes of deaths. Little is known about the burden of heart disease in pregnant South Africans. METHODS We systematically reviewed the contemporary epidemiology and peripartum outcomes of heart disease in South African women(More)
The South African Government recently set targets to reduce cardiovascular disease (CVD) by lowering salt consumption. We conducted an extended cost-effectiveness analysis (ECEA) to model the potential health and economic impacts of this salt policy. We used surveys and epidemiologic studies to estimate reductions in CVD resulting from lower salt intake. We(More)
SBA is a rare tumour which carries a poor prognosis. Very few data on prognostic factors and treatment outcomes are available. We conducted a retrospective analysis of patients treated for SBA at our institution. Clinico-pathological characteristics, treatments and outcomes of all the SBA patients treated consecutively from 1996 to 2011 were retrospectively(More)
BACKGROUND The burden of cardiovascular disease (CVD) and CVD risk conditions is rapidly increasing in low- and middle-income countries, where health systems are generally ill-equipped to manage chronic disease. Policy makers need an understanding of the magnitude and drivers of the costs of cardiovascular disease related conditions to make decisions on how(More)
Forty cases of endocardial thrombosis of the heart were selected for pathologic study from a total of 9,500 autopsies performed during 1936 to 1951. Widespread focal involvement of the connective tissue throughout the body and particularly in the heart was demonstrated. Although the histopathologic features were similar to those found in the "diffuse(More)
BACKGROUND Rheumatic heart disease (RHD) is the principal cause of acquired heart disease affecting people living largely in poverty and deprived conditions. Sub-Saharan Africa was long thought to be the hotspot of the disease but recent reports suggest that this is no longer the case. South Africa is the leading economic force within this region yet(More)
BACKGROUND Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) persist in many low- and middle-income countries. To date, the cost-effectiveness of population-based, combined primary and secondary prevention strategies has not been assessed. In the Pinar del Rio province of Cuba, a comprehensive ARF/RHD control program was undertaken over(More)
The present study examined the practice of forgiveness in Nepal. A model relating collectivism and forgiveness was examined. Participants (N = 221) completed measures of collectivism, individualism, forgiveness, conciliatory behavior, and motivations for avoidance and revenge toward the offender. Collectivism was positively related to forgiveness.(More)
Oesophagogastric adenocarcinoma (OGA) has a poor prognosis, even for patients with operable disease. However, the optimal surveillance strategy following surgery is unknown. We performed a retrospective review of all patients with OGA who had undergone surgery with radical intent at the Royal Marsden between January 2001 and December 2010. Of the 360(More)
