艾滋病儿童神经认知障碍相关因素研究进展

目的 总结艾滋病儿童神经认知障碍影响因素。方法 在PubMed、Web of Science、CNKI、万方和维普数据库，以“艾滋病”、“儿童”、“神经认知障碍”、“脑病”、“影响因素”为主题词或关键词，同时辅以手工检索和文献追溯检索近年相关文献。着重整理影响艾滋病儿童神经认知障碍的因素。对资料进行汇总并撰写综述。结果 检索并阅读相关文献100余篇。艾滋病病毒相关因素（HIV损害中枢神经系统、HIV逃逸及病毒储存库、HIV亚型）、宿主因素（启动抗病毒治疗时机、遗传因素、营养状况及合并其他疾病）、抗病毒治疗药物、社会心理因素等均可影响艾滋病感染儿童神经认知。结论 为了尽可能避免或降低艾滋病儿童神经认知障碍，应当尽早诊断、尽早给予高效的抗逆转录病毒治疗；随访中应重视神经认知发育的观察和筛查，及早识别神经认知障碍，积极寻找多方面的原因并进行有效干预。     

Video-assisted thoracoscopic surgery for thoracic empyema in patients on maintenance hemodialysis

Thoracic empyema in uremic patients on maintenance hemodialysis is a challenging situation. The clinical characteristics are rarely reported, and the surgical outcomes remain unclear. We report our experience with video-assisted thoracoscopic surgery in these patients during 10-year period of time. Between 2005 and 2015, we retrospectively reviewed the clinical characteristics, bacteriological studies, and thoracoscopic surgical results of 23 empyema patients undergoing maintenance hemodialysis. The mean patient age was 67.1 ± 12.9 years. All patients had additional preexisting systemic diseases. The mean duration of hemodialysis was 34.7 ± 25.8 months. The infections causing empyema were pneumonia in 11 (47.8%), blood stream infection in 8 (34.8%), and uremic pleuritis in 4 (17.4%). Among the 22 identified microorganisms, the most common pathogen was methicillin-resistant Staphylococcus aureus (31.8%). After thoracoscopic surgery, 8 patients (34.8%) required additional procedures for complications, including 2 patients who required repeated thoracoscopy for hemothorax and 6 (26.1%) patients who required open drainage for residual empyema. The mean hospital stay was 62.4 days, and 6 patients (26.1%) died in the hospital. Univariate and multivariate analyses revealed that maintenance hemodialysis longer than 5 years was a significant factor associated with in-hospital mortality (odds ratio: 14.8, 95% confidence interval 1.5–151.6; p < 0.0001). While surgical management of thoracic empyema in uremic patients undergoing maintenance hemodialysis is associated with high rates of complication and mortality, thoracoscopic surgery is feasible, especially for patients undergoing hemodialysis for less than 5 years.     

嵌顿痔不同治疗方法疗效分析

目的探讨嵌顿痔不同治疗方法的疗效。方法回顾性分析2009年8月至2012年8月迁西县人民医院确诊为嵌顿痔的160例患者的临床资料,其中采取外剥内扎法的80例患者作为A组,吻合器痔上黏膜环切术(PPH)结合外痔血栓剥除术的80例患者作为B组。对比分析两组患者的手术时间、住院时间、住院费用等指标及临床疗效,对比分析两组术后6个月并发症发生情况。结果B组患者的手术时间、住院时间显著少于A组[(15.4±1.1)min比(38.7±0.5)min,(5.3±0.6)d比(12.4±1.3)d,P<0.01];B组患者的有效率显著高于A组(88.8%比66.3%),而总体并发症发生率及复发率显著低于A组(17.5%比33.8%,5%比18.8%,P<0.05)。结论 PPH结合外痔血栓剥除术临床疗效显著。     

Intravenous Thrombolysis Is Safe and Effective for the Cryptogenic Stroke in China: Data From the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS-China)

Background

The intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) therapy is safe and efficient during the treatment of acute ischemic stroke. Nonetheless, the different outcomes among various stroke subgroups have limited data with regard to the safety and efficacy of cryptogenic stroke (CS). The present study compared the safety and efficacy when IVT with rt-PA was used for the treatment of CS and the other stroke subtypes.

四方联动防跌护理在社区跌倒高危老年人中的应用

目的探讨专科护士-社区护士-个体-家庭四方联动防跌护理模式在社区跌倒高危老年人中的应用与效果。方法选取深圳市龙岗区的2个社区,随机分为观察组和对照组,从两个社区登记建档的跌倒高风险老年居民中分别随机抽选45名进行干预。观察组采用"专科护士-社区护士-个体-家庭"四方联动推进的综合干预方案。对照组接受社区防跌倒常规护理。于干预前及干预后12个月使用修订版社区老年人跌倒危险评估量表、步态和平衡测试量表对两组老年人进行评测,记录两组1年内跌倒发生例次。结果干预期间跌倒发生情况:观察组1人次,对照组6人次。观察组步态和平衡测试得分提高,跌倒危险评估表得分降低,与对照组比较,差异有统计学意义(均P0.01)。结论四方联动的综合干预方案应用于社区居家老年人,能有效降低老年人跌倒风险,提升其防跌能力,对预防社区老年人跌倒的发生有积极作用。     

Entitlement: The big problem in medical education we will not talk about

Abstract

Entitlement is a problem in medical education that has received relatively little attention. First, it is felt by educators, who often feel pressured to conform curricula and evaluations to satisfy learner demands and administrative pressures lest their careers are penalized. Second, entitlement affects the medical system, as entitled physicians are less empathetic and focus more on personal goods rather than patient needs. This shifts the humanistic basis for medicine. Thirdly, entitlement is problematic for learners, as constant accommodations ironically undermine self-reliance and adaptability. Constantly meeting these demands can diminish gratitude and overall happiness. To address this issue, learners must acknowledge the problem and seek remedies to it themselves, as top-down interventions will likely be rebuffed. Rather than focusing solely on the learning environment, solutions should also empower learners to engage their environment in effective and productive ways. This should include correcting cognitive distortions that lead learners to expect administrative interventions in all circumstances perceived as harmful. Other solutions include practicing gratitude and developing work friendships. While certainly not all learners are entitled and some environmental amendments should be made, learners and educators must realize that entitlement is shaping medical culture and collectively take steps to mitigate its negative effects.
