Objectives Indoor air pollution is associated with impaired respiratory health. The pre-dominant indoor air pollutant to which two billion of the world's population is exposed is biomass fuel smoke. We tested the hypothesis that reported smoke exposure in men and women is associated with increased alveolar macrophage uptake of biomass smoke particulates.
Methods Healthy volunteers attending for research bronchoscopy in Malawi completed a questionnaire assessment of smoke exposure. Particulate matter visible in alveolar macrophages (AM) was quantified using digital image analysis. The geometric mean of the percentage area of the cytoplasm occupied by particulates in 50 cover-slip adherent AM was calculated and termed particulate load.
Results In 57 subjects (40 men and 17 women) there was a significant difference between the particulate load in groups divided according to pre-dominant lighting form used at home ( anova P = 0.0009) and type of cooking fuel ( P = 0.0078).
Conclusions Particulate load observed in macrophages is associated with the reported type of biomass fuel exposure. Macrophage function in relation to respiratory health should now be investigated in biomass smoke exposed subjects. 相似文献

The Institute of Medicine's (IOM's) Academy of Science has recommended that medical schools incorporate information on CAM (complementary and alternative medicine) into required medical school curricula so that graduates will be able to competently advise their patients in the use of CAM. The report states a need to study models of systems that integrate CAM and allopathic medicine. The authors present Cuba's health care system as one such model and describe how CAM (or natural and traditional medicine) is integrated into all levels of clinical care and medical education in Cuba. The authors examine the Cuban medical school curriculum in which students, residents, and practicing physicians are oriented in the two paradigms of CAM and allopathic medicine. Only health professionals are permitted to practice CAM in Cuba; therefore, Cuba's medical education curriculum incorporates not only teaching about CAM, but it also teaches basic CAM approaches and clinical skills. Both the theory and practice of CAM are integrated into courses throughout the six-year curriculum. Similarities and differences between the U.S. and Cuban approaches to CAM are examined, including issues of access and cost, and levels of acceptance by the medical profession and by the public at large in both countries. The authors conclude that there is potentially much to learn from the Cuban experience to inform U.S. medical educators and institutions in their endeavors to comply with the IOM recommendations and to incorporate CAM into medical school curricula. 相似文献

We conducted this study to determine the prognostic significance of the platelet count in children with cerebral malaria. We studied children with cerebral malaria admitted to the pediatric research ward at Queen Elizabeth Central Hospital, Malawi. We analyzed 1,811 children with cerebral malaria and compared them with 521 children with bacterial meningitis. There was a significant difference in platelet counts between children with cerebral malaria and those with meningitis. Among children with cerebral malaria, there was no relationship between the platelet count and either the admission coma score or the eventual outcome. Those with malarial retinopathy were more thrombocytopenic than those without. Our results suggest that the platelet count is not prognostic in Malawian children with cerebral malaria. 相似文献

BACKGROUND: Previous prospective studies of bacteremia in African children with severe malaria have mainly included children with cerebral malaria, and no study has examined the impact of human immunodeficiency virus (HIV) infection. We examined the prevalence and etiology of bacteremia and the impact of HIV infection on bacteremia in Malawian children with severe malaria, as well as the impact of bacteremia and HIV infection on outcome. METHODS: From 1996 until 2005, blood for culture was obtained on admission from all children admitted with severe malaria during the rainy season to the Paediatric Research Ward at the Queen Elizabeth Central Hospital in Blantyre, Malawi. HIV testing was performed prospectively from 2001 to 2005 and retrospectively for those admitted from 1996 to 2000. Multivariate regression analysis examined independent risk factors for bacteremia and death. RESULTS: Sixty-four (4.6%) of 1388 children with severe malaria had bacteremia; nontyphoidal Salmonellae (NTS) accounted for 58% of all bacteremias. The prevalence of any bacteremia and of NTS bacteremia was highest in children with severe malarial anemia (11.7% and 7.6%), compared with the prevalence in children with cerebral malaria and severe anemia (4.7% and 3.8%) and in those with cerebral malaria alone (3.0% and 0.9%). HIV infection status was determined in 1119 patients. HIV prevalence was 16% (and was highest in those with severe malaria anemia, at 20.4%), but HIV infection was not significantly associated with bacteremia. Neither bacteremia nor HIV infection was associated with death. CONCLUSIONS: Antibiotics are not routinely indicated for children with severe malaria in this region, in which HIV is endemic. However, antibiotic therapy should be used to treat NTS infection if bacteremia is suspected in children with severe malarial anemia. 相似文献
