本研究旨在明确心力衰竭（HE）胸片表现对因呼吸困难急诊住院病人诊断的准确性。运用BASEL次级分析，由2位放射学医师在不知确诊结果的情况下（56％最终诊断为HF），盲法分析227例急性呼吸困难病人的首诊胸片。使用预先定义的HF胸片诊... 详细信息

本研究旨在明确心力衰竭（HE）胸片表现对因呼吸困难急诊住院病人诊断的准确性。运用BASEL次级分析，由2位放射学医师在不知确诊结果的情况下（56％最终诊断为HF），盲法分析227例急性呼吸困难病人的首诊胸片。使用预先定义的HF胸片诊断标准，统计方法包括受试者工作特征（ROC）曲线分析和logistic回归模型计算B型利钠肽（BNP）水平。阅片者的整体印象表明仰卧位及立位胸片诊断HF的ROC曲线下最大面积分别为0．855和0．857。在各种影像表现中，

We performed the optical spectroscopy of 16 classical Be stars in 11 open clusters older than 100 *** is the first spectroscopic study of classical Be stars in open clusters older than 100 *** found that the Hαemission strength of most of the stars is less than 40?,in agreement with previous *** analysis further suggests that one of the stars,[KW97]35–12,might be a weak Hαemitter in nature,showing Hαequivalent width of-0.5?.Interestingly,we also found that the newly detected classical Be star LSⅢ+4737b might be a component of the possible visual binary system LSⅢ+4737,where the other companion is also a classical Be ***,the present study indicates the possible detection of a binary Be ***,it is observed that all 16 stars exhibit a lesser number of emission lines compared to classical Be stars younger than 100 ***,the spectral type distribution analysis of B-type and classical Be stars for the selected clusters points out that the existence of CBe stars can depend on the spectral type distribution of B-type stars present in these clusters.

When caring for children who become suddenly and catastrophically ill, clinicians must simultaneously attend to a complex and rapidly evolving medical situation, as well as to the equally challenging demands of establishing compassionate relationships with family members and communicating well with colleagues. An 18-month-old toddler was brought to the hospital with severe head injury after being struck by a car. Over a period of hours, her condition evolved from prognostic uncertainty to the diagnosis of brain death and considerations of organ *** this medical backdrop, the clinicians successfully established a trusting relationship with family members by careful attention to their emotional, informational, and care needs as they absorbed the devastating prognosis,took in the results of the brain death examination, and considered the option of organ donation. this case illustrates the importance of interdisciplinary communication,the vital role of social workers and other psychosocial providers with expertise in working with families, and the critical significance of mutual care and support for the clinicians who accompany families through these tragiclife events.

微伏级t波电交替(MtWA)被认为是一种识别缺血性心肌病高危患者的有效工具。然而,既往研究提示MtWA的预后预测效用可能仅限于QRS波群时间正常的患者。因此,本研究拟评估MtWA和QRS波群时间>120ms可否独立预测缺血性心肌病患者的死亡率,以及MtWA的预测价值是否因QRS波群时间不同而有所差异。总共768例连续、无室性心律失常病史的缺血性心肌病患者(LVEF≤35%)入选研究,

背景心外手术过程中的高血压常难以控制，并进而影响手术疗效。氯维地平是一种新型的2-氢吡啶L型钙通道阻滞剂，可有效降低动脉压，起效迅速，且半衰期极短。氯维地平治疗围手术期高血压的安全性事件评估研究（evaluation of clevidipine in the perioperative treatment of hypertension assessing safety events trial, ECLIPSE）旨在比较氯维地平（CLV）与硝酸甘油（NtG）、硝普钠（SNP）、尼卡地平（NIC）治疗心外手术患者急性高血压的疗效与安全性。方法我们分析了3项前瞻性、随机、开放性平行对照研究的资料，这些研究由61家医疗中心参与完成，比较了氯维地平与硝酸甘油、硝普钠、尼卡地平在心外手术患者的围手术期应用情况。共选择1964例患者，1512例按临床标准需紧急治疗高血压，符合随机化纳入标准。这些患者按1：1比例随机编入3个平行的对比治疗组。主要结局为30天内的死亡事件、心肌梗死、中风和肾功能不全，次要结局为血压控制的充分性与精确度的评估报告。结果氯维地平组与其他治疗组相比，心肌梗死、中风和肾功能不全的发生率均无显著差异。硝普钠治疗组与氯维地平组相比，死亡例数显著增加（P=0．04）。与硝酸甘油（P=0．0006）和硝普钠（P=0．003）相比，氯维地平能更有效地把血压控制在预定范围内。在控制血压于一个预定范围方面氯维地平与尼卡地平等效，但当预定血压控制范围较窄时，氯维地平较尼卡地平超出范围的幅度更小。结论氯维地平用于治疗心外手术患者的急性高血压安全有效。
