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.     

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.

2016至2018年某医院真菌血流感染者流行病学特征及耐药性分析

目的分析真菌性血流感染的病原菌分布以及耐药特征，为真菌血流感染的早期合理用药提供理论依据。 方法回顾性分析武汉大学人民医院2016年1月至2018年12月收治的真菌性血流感染者的菌群、科室分布以及耐药性。 结果入组192例真菌血流感染者的血培养样本中共分离192株真菌，其中白色念珠菌检出率为31.77%（61/192），其次热带念珠菌检出率为18.75%（36/192）；重症医学科检出率最高为33.85%（65/192）。所有菌株均对两性霉素B敏感，对其他抗菌药物耐药率分别为5-氟胞嘧啶4.49%（9/192）、伊曲康唑5.73%（11/192）、氟康唑10.94%（21/192）和伏立康唑11.46%（22/192）；除两性霉素B外，2016至2018年真菌对其他抗菌药物的耐药率均逐年上升，其中2018年所分离192株光滑念珠菌对伊曲康唑耐药菌率达46.7%。 结论真菌血流感染病原菌以念珠菌属为主，对目前抗真菌药物具有较高敏感性，但耐药率逐年上升，加强监测血培养病原菌变化及耐药趋势对指导临床用药至关重要。     

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.
