BACKGROUND Tranexamic acid(TXA),a synthetic antifibrinolytic drug,effectively reduces blood loss by inhibiting plasmin-induced fibrin *** is the first study in the United Kingdom to investigate the effectiveness of TXA in the surgical management of isolated spine *** To assess the safety of TXA in isolated spine *** primary and secondary outcomes are to assess the rate of thromboembolic events and to evaluate blood loss and the incidence of blood transfusion,*** This prospective observational study included patients aged≥17 years with isolated spine trauma requiring surgical intervention over a 6-month period at two major trauma centers in the United *** We identified 67 patients:26(39%)and 41(61%)received and did not receive TXA,*** groups were matched in terms of age,gender,American Society of Anesthesiologists grade,and mechanism of injury.A higher proportion of patients who received TXA had a subaxial cervical spine injury classification or thoracolumbar injury classification score>4(74%vs 56%).All patients in the TXA group underwent an open approach with a mean of 5 spinal levels involved and an average operative time of 203 min,compared with 24 patients(58%)in the non TXA group who underwent an open approach with an average of 3 spinal levels involved and a mean operative time of 159 *** patients who received TXA,blood loss was<150 and 150–300 mL in 8(31%)and 15(58%)patients,*** were no cases of thromboembolic events in any patient who received *** Our study demonstrated that TXA is safe for isolated spine *** is challenging to determine whether TXA effectively reduces blood loss because most surgeons prefer TXA for open or multilevel ***,larger studies are necessary to explore the rate,dosage,and mode of administration of TXA.

干旱是广泛影响经济和环境的主要自然灾害之一。因此,有必要采用诸如标准化降雨指数(SPI)等指标来研究干旱的影响,以辨析决策和规划的现实条件。本研究的目的是利用SPI指数分析伊朗南部法尔斯省的干旱空间格局。本文根据法尔斯省42个站点的数据,对1990-2019年间的干旱灾害格局进行了评价。评价模型中使用的干旱危害标准包括:该时期的最严重干旱程度、干旱趋势和连续干旱年的最大数量,最终的干旱灾害图是通过计算干旱强度、连续性和趋势三个指标的算术平均值获得的。三个指标的灾害图和最终灾害脆弱图采用反距离加权法(IDW)插值制图,分为无、轻度、中度、重度和极重度5个危害等级。最终的干旱脆弱性图显示,在研究区南部观察到的中度灾害区域占研究区36%,比在北部和中部观察到的严重和非常严重灾害区(占研究区64%)分布范围更小。
