Acute liver injury,acute liver failure and acute on chronic liver failure: A clinical spectrum of poisoning due to Gyromitra esculenta

Gyromitra esculenta, also known as “false morel” is one of the most poisonous mushrooms. This species is found all over the world, growing in coniferous forest in early spring time. Common manifestation of poisoning includes gastrointestinal symptoms which include varied degrees of liver impairment.We describe three cases: acute liver injury, acute liver failure and acute-on-chronic liver failure due to G. esculenta poisoning. At admission patients presented with encephalopathy and features of liver failure. Two of them recovered completely following supportive management while the remaining patient who also had preexisting liver disease developed multiorgan failure and subsequently died.Although a rare occurrence, G. esculenta poisoning should be considered in the differential diagnosis of acute liver failure.     

Respiratory support in children

Respiratory failure is defined by the inability of the respiratory system to adequately deliver oxygen or remove carbon dioxide from the pulmonary circulation resulting in hypoxemia, hypercapnia or both. A wide variety of disease processes can lead to respiratory failure in children. Multiple interventions can support the paediatric patient with respiratory failure, from simple oxygen delivery devices to high frequency oscillatory ventilation and extracorporeal membrane oxygenation. This article will review available devices to improve oxygenation and ventilation, their advantages and disadvantages, and help guide physicians in the management of children with respiratory failure.     

呼吸专科护士慢性呼吸疾病管理现状调查

目的调查呼吸专科护士慢性呼吸疾病管理现状,为提高慢性呼吸疾病的管理水平提供参考。方法依据《中国成人慢性呼吸疾病患者护理管理指南》设计调查问卷,对重庆、四川、贵州、陕西、河北、湖北、海南7省市的205名呼吸专科护士进行问卷调查。结果呼吸专科护士慢性呼吸疾病管理总分为(140.72±23.90)分。慢性呼吸疾病管理得分最低的3个条目有评估工具应用、个性化管理计划的实施、慢阻肺随访的次数及指导哮喘患者使用峰流速仪;呼吸专科护士所在单位慢性呼吸疾病管理平台建设均低于50%。结论呼吸专科护士慢性呼吸疾病管理处于中等偏下水平,评估是慢性呼吸疾病管理的薄弱点。需加强呼吸专科护士专业能力培养,规范慢性呼吸疾病全程管理,强化医院平台建设等,提高慢性呼吸疾病的管理水平。     

沙库巴曲缬沙坦在心力衰竭治疗中的应用

心力衰竭是一种慢性疾病，是心脏无法泵出足够的血液为其他身体器官提供氧气，从而引发呼吸短促、疲劳和水肿等症状。目前其治疗包括病因治疗、一般治疗、药物治疗及非药物治疗等，其中血管紧张素受体脑啡肽酶抑制剂（ARNI）是当前新研发出的一类抗心衰药物，沙库巴曲缬沙坦是其代表药物，具有阻断肾素-血管紧张-醛固酮系统（RAAS）及抑制脑啡肽酶（NEP）的双重作用，新的欧美指南均推荐用于射血分数降低心力衰竭（HFrEF）的治疗。本文现就沙库巴曲缬沙坦在心力衰竭治疗中的作用机理、临床试验、药物安全性作一综述，旨在为该病的临床治疗提供参考。
