Clinical Course of Patients With Worsening Heart Failure With Reduced Ejection Fraction

Background

Epidemiology of patients with worsening heart failure and reduced ejection fraction (HFrEF) in the real-world setting is not well described.

肉毒毒素注射引起的不良反应

肉毒毒素注射引起的不良反应,是药物本身的组成成分引起的与用药目的无关的有害反应,与医生注射方式和注射技术无关。尽管肉毒毒素生产厂家的药品说明书上也有提示,但其所提供的信息不够全面,也未必能引起医生的足够重视。目前文献上多为散发病例。为此作者对过去20年有关肉毒毒素注射引起的过敏反应、肉瘤样肉芽肿、眼睑水肿、流感样症状等相关不良反应的临床表现、发病机制与治疗方法进行综述。     

The Effect of Residential Aged Care Size,Ownership Model,and Multichain Affiliation on Resident Comfort and Symptom Management at the End of Life

Context

In most resource-rich countries, a large and growing proportion of older adults with complex needs will die while in a residential aged care (RAC) facility.

The use of augmented toys to facilitate play in school-aged children with visual impairments

BackgroundChildren with visual impairments (VIs) face challenges in social play activities, which limits their opportunities to practice social skills.AimsWe investigated whether augmented toys were effective to facilitate play in 52 children with VIs who attended special schools for students with visual impairments and blindness.Methods and procedures52 children with VIs (mean age: 9.22 years, SD = 2.07) played three times with both an augmented and a non-augmented toy. A Playmobil® knight’s castle was augmented with Radio Frequency Identification (RFID) technology, such that each play figure produced audio feedback during play. The RFID-technology could be activated and deactivated. Social and cognitive aspects of play were coded from video and data were analyzed using multilevel logistics.Outcomes and resultsChildren showed less disengagement and more parallel play, but less cooperative play when they used the augmented versus the non-augmented castle. This pattern persisted after repeated play sessions with both toys.ConclusionsThe addition of sounds to physical toys increased shared attention between children with VIs during the exploration of play materials, yet it interfered with social interaction during peer play.     

中药灌洗负压治疗糖尿病足创面的疗效观察

目的:观察中药灌洗负压治疗糖足创面的临床疗效。方法:将60例糖尿病足住院患者随机分为观察组30例和对照组30例。观察组给予常规基础及中药灌洗负压技术治疗,对照组给予常规基础及盐水灌洗负压治疗,疗程为21 d,观察两组患者全血白细胞计数、C反应蛋白、创面面积变化、创面缩小率、换药次数及创面局部各症状积分的变化情况。结果:近期疗效结果表明观察组总有效率96.67%,明显高于对照组的90%(P0.05)。两组患者创面局部各症状积分治疗前后对比,差异有统计学意义(P0.05)。治疗后,观察组WBC、CRP、创面面积及换药次数等观察指标分别为(5.86±1.37)×109/L、(4.59±1.10) mg/L、(5.81±2.01) cm~2、(5.33±0.92)次,均明显低于对照组,治疗后创面缩小率(25.06±5.91)%明显高于对照组。结论:临床上应用中药灌洗负压技术治疗糖尿病足创面,可以明显缩短创面愈合时间,提高愈合率,减少换药次数,减轻患者换药痛苦和医护人员工作量。在治疗上具有自己的特色和优势,值得临床进一步推广应用。     

Exercise Intolerance in Patients With Heart Failure: JACC State-of-the-Art Review

Exercise intolerance is the cardinal symptom of heart failure (HF) and is of crucial relevance, because it is associated with a poor quality of life and increased mortality. While impaired cardiac reserve is considered to be central in HF, reduced exercise and functional capacity are the result of key patient characteristics and multisystem dysfunction, including aging, impaired pulmonary reserve, as well as peripheral and respiratory skeletal muscle dysfunction. We herein review the different modalities to quantify exercise intolerance, the pathophysiology of HF, and comorbid conditions as they lead to reductions in exercise and functional capacity, highlighting the fact that distinct causes may coexist and variably contribute to exercise intolerance in patients with HF.
