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.

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.     

亮氨酸氨基肽酶在妊娠妇女血清中的水平变化及其意义

目的:探讨血清亮氨酸氨基肽酶(LAP)在妊娠妇女不同时期血清中的变化规律及其临床意义。方法:选取2011年1月~2013年12月在该院产检的正常妊娠妇女180例,根据孕周分为早期组、中期组和晚期组,每组各60例,另选取60例健康未孕妇女为未孕组;同时选取该院收治的妊娠期高血压疾病妇女33例为妊娠期高血压疾病组、早产孕妇22例为早产组,采用速率法分别检测各组孕妇血清LAP水平并进行比较。结果:未孕组、早期组、中期组、晚期组妇女的血清LAP、血清肝胆酸(CG)、碱性磷酸酶(ALP)、α-L-岩藻糖苷酶(AFU)水平比较,差异有统计学意义(P均<0.05)。妊娠期高血压疾病组的CG、ALP、AFU、LAP水平显著高于早期组、中期组和晚期组(P均<0.05);早产组的CG、ALP、AFU、LAP水平显著高于早期组、中期组(P均<0.05),仅CG水平高于晚期组(P<0.05)。结论:随着妊娠周期的增加,妊娠妇女的血清LAP水平逐步升高,在合并妊娠期高血压疾病时LAP升高更加显著,结合CG、ALP、AFU水平的变化能够对妊娠期高血压疾病的发病情况进行动态监测。
