There has been a dramatic increase in medical complications related to synthetic cannabinoid (SC) use either by water pipe or vaping. The legalization of marijuana in an increasing number of states has also resulted in an increase in a number of complications related not just to marijuana, but in particular, to SC. As a result, there have been recent increased reports of acute pulmonary injury related to inhaled SC products. We describe that rarely endotracheal intubation with mechanical ventilation has been required to treat the acute respiratory distress syndrome (ARDS) and the diffuse alveolar hemorrhage (DAH) associated with the acute toxicity of SC inhalation. We describe the second reported case of successful utilization of mechanical ventilation and extracorporeal membrane oxygenation (ECMO) in order to treat acute pulmonary toxicity caused by SC inhalation by a water pipe. While the exact pathophysiology of these interesting and recent pulmonary complications is unknown, the recent increase in exposure to SC via water pipe systems and vaping suggests that there will be many more cases of patients that will require ECMO as a form of life-saving therapy.

进行了一系列室内试验,以验证模拟细沟演变动态过程的数学模型。该模型模拟了细沟水流的动态过程、水力学特性参数的空间变化、细沟中土壤的剥离、运输及沉积过程;模拟了细沟在侵蚀过程中的形态演变,其中包括沟宽、沟深、局部坡度在空间上的差异及其随时间的变化;模拟了细沟侵蚀/泥沙沉积后局部细沟形态的变化对细沟水流反馈效应。试验土壤为砂壤土,采用的坡度为:3%,5%,7%;3个流量:7.6,11.4,15.2L/min。在同一试验条件不同工况下对模型进行了验证,同时对细沟中沿程水流速度和细沟末端的侵蚀产沙量进行了模拟值和试验实测值的对比。结果表明,模型预测值和实测细沟形态演变值具有很好的一致性,模型中提出的侵蚀、沟床形态变化和水力学特性参数间的互反馈环效应可以反映细沟侵蚀的动态演变过程和发展趋势。

Colour-ring wear and loss effects in citizen science mark-resighting studies

Avian Research 2019年第2期10卷 148-162页

Background: Ring wear and loss may have important consequences for mark-recapture studies that aim to estimate survival trends. Our study quantifies the rates of wear and loss from a long-running colour-ringing project of the Eurasian Oystercatcher (Haematopus ostralegus) in the Netherlands. Methods: Our analysis included 8909 colour-ringed oystercatchers with 118,071 resightings, predominantly ringed and observed by citizen scientists. We quantified how ring wear and loss may vary with ring colour and age, and how this may impact resighting probabilities. We then determined how ring loss may impact survival estimates and resighting probabilities of mark-recapture models by simulating four scenarios of how citizen scientists may resight and report birds with lost colour rings. Results: Annual rates of colour ring loss averaged 2.5% compared with 1% for ring wear, but lost rings also had a higher reporting probability (31.2%) than worn rings (10.3%). Lost rings may not directly impact survival estimates since 50% of oystercatchers with lost rings could still be uniquely identified. Ring wear and loss rapidly increased between 10 and 15 years after ringing. Rates of ring loss were comparable amongst ring colours, but the wear rate appeared higher for red and white rings compared to other colours. Rates of ring wear and loss varied significantly amongst different regions in our study, which were characterised as having different habitat features. Differential rates of ring wear may have important implications for studies conducted over large geographical scales or of multiple species. Conclusions: Based on simulations of ring loss in our population, estimates of apparent survival may be 0.3–1.2% lower whilst the impact of ring wear was deemed even lower. We developed a table of recommendations containing advice for ring fitting, data collection, study design, and mark-recapture analyses, so that future colour-ringing studies can benefit from our experiences in collecti
