ADAM33 polymorphisms and susceptibility to allergic rhinitis: a meta-analysis

European Archives of Oto-Rhino-Laryngology - Several polymorphisms in a disintegrin and metalloproteinase 33 (ADAM33) have been implicated in susceptibility to allergic rhinitis (AR), but the...     

In Vivo Kinematics of Functional Ankle Instability Patients and Lateral Ankle Sprain Copers During Stair Descent

Patients with mechanic ankle instability experience increased tibiotalar and subtalar joint laxity. However, in vivo joint kinematics in functional ankle instability (FAI) patients and lateral ankle sprain (LAS) copers, especially during dynamic activities, are poorly understood. Ten FAI patients, 10 LAS copers, and 10 healthy controls were included in this study. A dual fluoroscopic imaging system was used to analyze the tibiotalar and subtalar joint kinematics during stair descent. Five key poses of stair descent were analyzed. Kinematic data from six degrees of freedom were calculated utilizing a solid modeling software. The range of motion and joint positions in each degree of freedom were compared among the three groups. The tibiotalar joints of FAI patients and LAS copers were significantly more inverted than those of healthy controls during the foot strike (p = 0.016, = 0.264). The subtalar joints of FAI patients were significantly more anteriorly translated (pose 2, p = 0.003, = 0.352; pose 3, p < 0.001, = 0.454; pose 4, p = 0.004, = 0.334), inverted (pose 4, p = 0.027, = 0.234; pose 5,p = 0.034, = 0.221), and externally rotated (pose 4, p = 0.037, = 0.217; pose 5; p = 0.004, = 0.331) than those of healthy controls during the mid‐stance and the heel off. The FAI patients showed excessive tibiotalar inversion and subtalar joint hypermobility during stair descent. Meanwhile, the LAS copers maintained subtalar joint stability, and only showed excessive tibiotalar inversion in foot strike. These data provide insight into the mechanisms behind the development of FAI after initial LAS. © 2019 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

深圳市制造企业90后新招产线员工心理弹性、应对方式与心理健康间的关系

目的探讨深圳市3家制造企业新招90后产线员工心理弹性、应对方式和心理健康间是否存在某种关系。方法在深圳市3家制造企业选取入职一周的新招90后产线员工,以其入职日期为单位进行整群抽样。应用心理弹性量表CDRISC、简易应对方式问卷SCSQ以及一般健康问卷GHQ-20三个量表分别测量其心理弹性、应对方式以及心理健康,并利用结构方程模型软件Amos 17.0进行路径分析。结果心理弹性与心理健康呈正相关关系(P<0.01);心理弹性和心理健康与积极应对呈正相关关系(P<0.01);心理弹性和心理健康与消极应对呈负相关关系(P<0.01);结构方程模型结果表明:心理弹性既可以直接影响心理健康,又可以通过积极应对和消极应对的中介作用间接影响心理健康。结论深圳市制造企业新招产线员工的心理弹性、应对方式与心理健康间存在线性相关关系,且心理弹性通过积极应对和消极应对对心理健康起着部分间接的作用。     

苯扎贝特治疗儿童ApoE Tokyo(Arg25Cys)突变型脂蛋白肾病1例

脂蛋白肾病(Lipoprotein glomerulopathy,LPG),1989年首次由日本学者Saito报道,LPG主要累及肾脏,且以肾小球病变为主[1]。几乎所有患者均有不同程度的蛋白尿,多数表现为肾病综合征,少数表现为轻微蛋白尿和镜下血尿,部分患者伴有不同程度的贫血及高血压,血脂异常易被忽略为肾病综合征的低蛋白血症所致。载脂蛋白E(apolipoprotein E,ApoE)增高是LPG血脂改变的主要特点[2-3]。LPG为一种与脂质代谢紊乱密切相关的肾脏疾病,目前世界范围内有报道的病例不足200例,儿童报道仅10余例[2]。本病进展缓慢,临床常误诊为原发性肾病综合征[4]。因此,为增强对LPG的认识,提高诊治水平,现分析1例确诊的儿童LPG临床资料,总结LPG的临床特点、诊断、治疗及预后。     

Hypertension is a risk factor for adverse outcomes in patients with coronavirus disease 2019: a cohort study

Abstract

Background

Comorbidities are commonly seen in patients with coronavirus disease 2019 (COVID-19), but the clinical implication is not yet well-delineated. We aim to characterize the prevalence and clinical implications of comorbidities in patients with COVID-19.
