马拉维最近的热浪导致连日的高温,这正是茶农们担心的情景。在过去的18个月里,我们与南部地区的小农户和大型茶叶生产商进行了合作,发现茶树被烤焦的风险是一个主要问题。前所未有的热浪根据气候变化和气象服务部的数据,10月下旬的10天里,(姆兰杰)含羞草气象站记录的气温超过35摄氏度,高达40摄氏度。热浪的结果是,被收割的茶树的叶子变成了褐色,枯萎了。

Ultrasound diagnosis of malaria: examination of the spleen, liver, and optic nerve sheath diameter

BACKGROUND: Over 90% of all cases of malaria worldwide occur in Africa. Current methods of diagnosis are time and labor intensive, and could lead to delayed ***: In this study we investigated the effectiveness of measurements of spleen, liver, and optic nerve sheath diameter(ONSD) in identifying patients with malaria or severe malaria through the use of hand-held ultrasound devices. We recruited 40 adult patients with malaria and 16 adult control subjects at two hospitals in Mwanza, Tanzania. Ultrasonographic diagnosis was compared with rapid antigen diagnostic test and peripheral blood smear as the gold standards. An receiver operating characteristic curve test was performed to determine the most optimal diagnostic threshold for malaria and severe malaria, using each of the measurements for liver size, spleen size, and ONSD. The thresholds were determined to be >12 cm for spleen length and >15.1 cm for liver length, whereas ONSD was not signifi cant in this ***: The sensitivities for malaria diagnosis were 66.7% and 58.3% for liver and spleen length respectively, suggesting that these measurements may not be suitable for identifying patients with severe malaria. However, the high specificity of 90.9% for spleen length and the acceptable specifi city of 75.0% for liver length suggest that these measurements can be used as a method to eliminate false-positive diagnoses(i.e. patients who do not have severe malaria but are classifi ed as having it by a test with a high sensitivity), giving a high positive predictive ***: We report a high specifi city for spleen size and a moderate specifi city for liver size in the ultrasonographic diagnosis of severe malaria. Thus when paired with a highly sensitive method of malaria diagnosis, ultrasonographic measurement of spleen and liver size is promising as part of a diagnostic algorithm for malaria. It could be used to stratify risk in patients diagnosed with malaria and assist in their tri

本项研究从定性方面探讨变性人在安大略省乡村医疗保健环境中遇到的障碍,分析了变性人如何克服这些障碍,以及如何加强医疗互动来提升他们个人代理体验的方法。安大略省乡村地区的12名变性者和3名医疗专业人士参与了这项开放式、半结构化的访谈,对访谈内容进行解释现象学和批评话语分析后,让我们深刻认识到了医疗保健互动中侵犯人权,安大略省变性病人在农村面临的挑战,非互惠关系对变性人个体的自我代理、自主性和心理健康体验等方面的影响,以及实现他们整体复原力和赋权的有利因素等问题,还探讨了变性人医疗保健的可行模式和未来研究方向等问题。
