Background: Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.

Despite the advances in the hematology field, blood transfusion-related iatrogenesis is still a major issue to be considered during such procedures due to blood antigenic incompatibility. This places pluripotent stem cells as a possible ally in the production of more suitable blood products. The present review article aims to provide a comprehensive summary of the state-of-theart concerning the differentiation of both embryonic stem cells and induced pluripotent stem cells to hematopoietic cell lines. Here, we review the most recently published protocols to achieve the production of blood cells for future application in hemotherapy, cancer therapy and basic research.

目的:分析和比较市售的粗糙表面螺纹种植体与多孔圆柱种植体在兔模型愈合的不同时期骨沉积情况。此外,研究种植体表面形态对变形链球菌粘附的影响。材料与方法:采用粉末冶金技术的新方法,制备有致密核心和多孔表面的钛种植体.以增加种植体骨结合率(BIC)。15只兔中,植入60个种植体。在每只兔子右、左侧胫骨各植入两个实验组和对照组种植体。实验组采用敲击就位,对照组自螺纹就位。术后4周、8周和12周处死动物.脱钙处理,检测种植体骨接触率。此外.在16个种植体(8个实验组,8个对照组)表面培养变形链球菌,评价细菌粘附情况。分别进行方差分析和t检验。结果:两组组织学均显示种植体-骨界面紧密接触.无软组织介入。多孔圆柱型种植体BIC(72.41%±9.47%)高于粗糙螺旋种植体(61.23%±14.12%)(P=O.013).而变形链球菌粘附情况无显著差异(P=O.351)。愈合4周时,两组间差距更明显(P=O.029)。两组间BIC在整个实验周期无显著性差异(P=O.333),但BIC随时间延长而提高。结论:在本研究条件.结果显示:新型种植体增加了BIC,且未增加变形链球菌粘附。

BACKGROUND Superior mesenteric artery syndrome(SMAS)is a rare condition,characterized by duodenal obstruction caused by compression of its third part by the superior mesenteric artery(SMA).Most cases of SMAS are associated with weight loss,and the most frequent clinical manifestations are nausea,vomiting,postprandial fullness,and abdominal *** of SMAS is usually conservative,consisting mainly of adequate nutritional support,but in refractory cases surgery may be necessary,with gastrojejunostomy and duodenojejunostomy being the most commonly performed *** SUMMARY We describe the case of a man in his forties with a pre-existing diagnosis of esophageal stricture due to sodium hydroxide ingestion,who suffered significant weight loss after replacement of his jejunostomy *** was admitted to the hospital due to pain and abdominal distension.A computerized tomography scan showed significant distension of the stomach and duodenum with narrowing of the duodenum at the point at which it is crossed by the superior mesenteric artery,thus establishing the diagnosis of *** to the presence of the esophageal stricture,the patient was incapable of emesis;however,passage of a nasogastric tube for decompression was not *** the risk of gastric perforation due to distention,we opted for surgical treatment in the form of a surgical gastrojejunostomy after which he showed complete resolution of all symptoms and was discharged from the hospital 5 d after the *** Diagnosis of SMAS can be challenging in patients with esophageal stenosis,and risk of gastric perforation may preclude conservative treatment.

加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。
