A model for emergency medicine education in post-conflict Liberia

AbstractThe specialty of emergency medicine (EM) remains largely underdeveloped in many parts of the world including Africa. Within West Africa the Liberian health care system was presented with incredible challenges in the immediate post conflict years. One significant challenge facing the country was the paucity of health care providers. In 2006, only 122 physicians were practising in Liberia (one for every 26,782 citizens), only 87 of them Liberian national physicians. The public health indicators in post conflict Liberia suffered as a result of the overburdened system. Many indicators placed Liberia as having the worst health survivability in the world. Significantly, morbidity and mortality associated with unaddressed emergent presentations remained high.This article describes a unique paradigm for addressing the deficit in human capacity for emergency health care in the Republic of Liberia. This system was designed and supported by a consortium of academic medical centres in the United States working in conjunction with a local non-governmental organisation, Health Education and Relief Through Teaching (HEARTT). Since 2007, the consortium has delivered virtually uninterrupted emergency medical care and medical education at the largest teaching hospital in Liberia. The Liberian programme objectives included supervising and directing emergency medical care, providing a model for curriculum development, building capacity for medical education, and improving systems-based EM practice. The collaboration of multiple academic institutions in bringing emergency medical services and academic EM teaching to a post-conflict setting remains a unique model for introducing the development of acute care in a developing country

HIV/AIDS, conflict and security in Africa: rethinking relationships

<p>Abstract</p> <p>The effect of conflict on HIV transmission and regional and global security has been the subject of much recent discussion and debate. Many long held assumptions regarding these relationships are being reconsidered. Conflict has long been assumed to contribute significantly to the spread of HIV infection. However, new research is casting doubt on this assumption. Studies from Africa suggest that conflict does not necessarily predispose to HIV transmission and indeed, there is evidence to suggest that recovery in the "post-conflict" state is potentially dangerous from the standpoint of HIV transmission. As well, refugee populations have been previously considered as highly infected vectors of HIV transmission. But in light of new investigation this belief is also being reconsidered. There has additionally been concern that high rates of HIV infection among many of the militaries of sub-Saharan Africa poses a threat to regional security. However, data is lacking on both dramatically elevated prevalence amongst soldiers and a possible negative effect on regional security. Nevertheless, HIV/AIDS remain a serious threat to population health and economic well being in this region. These issues are of vital importance for HIV programming and health sector development in conflict and "post-conflict" societies and will constitute formidable challenges to the international community. Further research is required to better inform the discussion of HIV, conflict, and security in sub-Saharan Africa.</p

Plaque area at carotid and common femoral bifurcations and prevalence of clinical cardiovascular disease

Aim. Different ultrasonic arterial wall measurements have been used as predictors of future myocardial infarction or stroke. The aim of the present study was to determine the relationship of total plaque area (TPA) (the sum of the atherosclerotic plaque area measurements from both carotid and both common femoral arteries) with prevalence of cardiovascular disease in a population-based cross-sectional study and compare it with intima-media thickness (IMT). Methods. Seven hundred sixty-two individuals (47% male) over the age of 40 were screened for cardiovascular risk factors. Results. Evidence of clinical cardiovascular disease was present in 113 (14.8%). Both carotid and both common femoral bifurcations were scanned with ultrasound. After adjustment for conventional risk factors the association of IMT with prevalence of clinical cardiovascular disease was low (P=0.84, OR of upper IMT quintile 1.36; 95% CI 0.56 to 3.26) and of TPA high (P<0.001, OR of upper TPA quintile 8.38; 95% CI 2.57 to 27.32). TPA greater than 42 mm2 (cut-point derived from ROC curve analysis) identified 266 (34.9%) of the population that contained 87/113 (76.9%) of the clinical events (sensitivity: 77%; specificity: 73%; positive predictive value: 33%; negative predictive value: 94%; positive likelihood ratio of 2.79). In contrast, IMT greater than 0.07 mm had a sensitivity, specificity, positive and negative predictive value and positive likelihood ratio of 68%, 60%, 23%, 91% and 1.69 respectively. Conclusion. Total plaque area appears to be more strongly associated with the prevalence of cardiovascular disease than IMT. This finding warrants further prospective studies
