Opposing patterns in self-reported and measured physical activity levels in middle-aged adults

Physical activity brings significant health benefits to middle-aged adults, although the research to date has been focused on late adulthood. This study aims to examine how ageing affects the self-reported and accelerometer-derived measures of physical activity levels in middle-aged adults. We employed the data recorded in the UK Biobank and analysed the physical activity levels of 2,998 participants (1381 men and 1617 women), based on self-completion questionnaire and accelerometry measurement of physical activity. We also assessed the musculoskeletal health of the participants using the dual-energy X-ray absorptiometry (DXA) measurements provided by the UK Biobank. Participants were categorised into three groups according to their age: group I younger middle-aged (40 to 49 years), group II older middle-aged (50 to 59 years), and group III oldest middle-aged (60 to 69 years). Self-reported physical activity level increased with age and was the highest in group III, followed by group II and I (P?<?0.05). On the contrary, physical activity measured by accelerometry decreased significantly with age from group I to III (P?<?0.05), and the same pertained to the measurements of musculoskeletal health (P?<?0.05). It was also shown that middle-aged adults mostly engaged in low and moderate intensity activities. The opposing trends of the self-reported and measured physical activity levels may suggest that middle-aged adults over-report their activity level as they age. They should be aware of the difference between their perceived and actual physical activity levels, and objective measures would be useful to prevent the decline in musculoskeletal health.

物联网技术在医院中的应用现状

物联网(Internet of Things,简称"IoT")技术是当前世界新一轮科技和经济发展的战略制高点之一。物联网是由传感技术感知物体,按照固定的协议实现任何时候物与物之间、人和物之间、人与人之间的互联互通,实现智能化识别、定位、跟踪及管理的网络,是信息技术和传感控制技术两者融合的产物。简单来说,物联网就是可以让人们所关注的事物在任何地方、任何时候都能被监控,其具有全面感知、可靠传递以及智能处理3个特点。物联网的核心是智能化,其在医院中的应用主要是实现对人的智能化医疗和对物的智能化管理工作,例如:实现婴儿防盗、无线输液管理、移动门诊输液管理等功能;用于医疗资产管理、资产定位,提升医疗器械调度效率。     

输尿管部分切除术治疗原发性输尿管癌的长期随访分析

目的:探讨保留肾脏的输尿管部分切除术治疗原发性输尿管癌的长期疗效。方法:回顾性分析1999年3月~2013年2月行保留肾脏的输尿管部分切除术的31例输尿管癌患者临床资料:12例患者行输尿管膀胱再植术,19例行输尿管端端吻合术。随访14~171个月,观察术后尿路肿瘤复发率、患者总体生存率、肿瘤分期及病理分级方面分层生存率等情况。结果:术后尿路肿瘤复发率为19.35%(6/31);总体5年及10年生存率分别为77.41%、58.64%;低肿瘤分期组5年及10年生存率均为86.67%,高肿瘤分期组5年及10年生存率分别为74.93%和54.29%;低病理分级组5年及10年生存率均为76.00%,高病理分级组5年及10年生存率分别为78.26%和48.83%。结论:在严密随访下,输尿管部分切除术可以有效治疗低分期、低分级输尿管癌。     

Pseudocystic pilomatricoma: A new variant and review of the literature

A classic pilomatricoma, which usually presents with an asymptomatic, solitary, firm, subcutaneous nodule in the head, neck, or extremities of the paediatric population, is easily diagnosed based on its characteristic clinical and histopathological features. However, its variants often pose particular diagnostic challenges to clinicians due to their rarity and diverse clinicopathological features. We present a new pseudocystic variant, manifesting as solid lesions floating in a fluid‐filled sac.
