TIC en actividad física y parámetros cardiovasculares en mayores: una revisión

IntroductionAgeing is a period of physical and psychological changes. Inactivity is one of the biggest problems among the older adult population increasing the risk of sarcopenia and chronic diseases. Physical activity is an effective intervention to improve health outcomes. In recent years, there has been an increase in the use of technology, with health technology tools (ICT) appearing as an intervention to increase physical activity and improve associated health problems.ObjectiveIn this review, we evaluated the effectiveness of health technology to increase physical activity and to improve cardiovascular parameters in older adults.MethodologyStudies with a great variety of health technology tools to increase physical activity levels, and that evaluated the effect of that increase on cardiovascular parameters were included by searching the main databases.ResultsEleven studies reporting the use of a variety of ICT tools were included in this review. Despite these differences, the effectiveness of health technology tool interventions has been demonstrated in increasing physical activity and reducing cardiovascular parameters.DiscussionThe lack of adherence of older adults to health technology would be a disadvantage, but it has been shown that younger older adults are more familiar with health technology tools and the number using them is increasing.ConclusionHealth technology tools show effectiveness in increasing physical activity in older adults and improving cardiovascular parameters.     

基于移动医疗的妊娠期盆底肌训练对产后尿失禁发生的影响：一项基于随机对照试验设计的探索性研究

背景 孕产妇尿失禁（UI）发病率高，严重影响了女性生活质量。研究表明，盆底肌训练是UI有效的防治手段，本研究前期进行了一项随机对照试验（RCT），结果发现相比于常规宣教，基于移动医疗APP的盆底肌训练并未显现出预防优势，其原因需要进一步深入探讨。 目的 本研究拟对一项基于APP的妊娠期盆底肌训练的干预研究的阴性结果进行探索性分析，旨在探讨产后UI预防效果的影响因素以及获益的亚组人群。 方法 本研究数据来源于前期开展的一项RCT，采用方便抽样法，于2020年6—10月在南方医科大学深圳医院产科门诊招募了126例研究对象，采用随机数字表法分为干预组与对照组，每组各63例。对照组采用常规护理，干预组在此基础上使用"有爱屋"APP进行尿失禁自我管理，干预周期为2个月。产后42 d随访时收集两组产后相关资料，包括产后42 d UI发生情况。以产后是否发生UI为结局指标，将研究对象分为病例组和对照组，采用Logistic回归分析探讨混杂因素及其与干预方式之间的交互作用对产后UI发生的影响。针对Logistic回归分析的结果进行分层分析，探讨是否存在能从APP干预中获益的亚组人群。 结果 病例组和对照组阴道分娩史、入组时存在UI、Broome盆底肌自我效能量表（BPMSES）得分比较，差异均有统计学意义（P<0.05）。Logistic回归分析结果显示，入组时存在UI是产后发生UI的危险因素〔OR=15.897，95%CI（4.724，53.495），P<0.001〕；BPMSES得分与干预方式的交互作用可影响产后UI的发生〔OR=1.034，95%CI（1.017，1.051），P<0.001〕。分层分析结果显示，入组时存在UI症状的孕妇，干预组产后UI发生率低于对照组（χ2=4.18，P=0.041）；入组时不存在UI症状的孕妇，两组产后UI发生率比较，差异无统计学意义（χ2=1.89，P=0.284）。 结论 推荐有UI症状的孕妇使用"有爱屋"APP或许可预防产后UI的发生。而对于妊娠期没有UI症状的人群使用"有爱屋"APP预防产后UI发生的证据尚不充分。另外，不管有无UI症状，盆底肌训练自我效能高的孕妇有望从APP干预中获益。     

适量运动对心房颤动患者预后的影响:系统综述与Meta分析

目的 分析适量运动对于心房颤动(房颤)患者的运动能力以及远期临床预后的影响。方法 通过检索中国知网,万方,维普,Pubmed,OVID,Cochrane Central Register of Controlled Trials (CENTRAL),web of science数据库,纳入对房颤患者进行适量体育活动干预的临床试验。本研究的主要终点为静息心率,最大心率,6 min步行试验,最大运动功率,全因死亡率以及卒中发生率,用以评估适量运动对房颤患者活动耐力以及预后的影响。结果 本研究共纳入7项试验,2 452例患者,试验组为适量运动干预组,对照组为不活跃组。适量运动并不会显著增加患者的静息心率(MD=-1.68,P=0.70)以及最大心率(RD=9.72,P=0.11)。运动训练可显著提高房颤患者的运动能力,明显增加6 min步行距离(MD=59.07,95%CI=11.70-106.44,P<0.05),并且在一定程度上提高运动功率(MD=17.96,95%CI=-6.30-42.22,P=0.15)。适量运动对房颤患者的远期预后不会造成不良影响,适量运动组对比不活跃组,全因死亡率为15.7% vs 14.2%(RD=0.03,95%CI=-0.18-0.25,P=0.75);卒中发生率5.0% vs 2.9%(RD=0.02,95%CI=-0.06-0.09,P=0.69),两组差异无统计学意义。结论 适量运动可在一定程度上提高房颤患的活动耐力,且不增加卒中以及全因死亡率。

MRCS Performance by OMFS trainees: an update and call to action

Completion of the Intercollegiate Membership of the Royal College of Surgeons (MRCS) examination is a prerequisite for completion of specialty surgical training in UK. The aim of this study was to compare MRCS performance of OMFS trainees to trainees in other specialities over the past 13 years. Differential attainment (DA) was noted in MRCS Part A (MCQ) pass rates. There was no statistically significant difference in MRCS Part B pass rates. The reasons for this DA are currently unknown and require further investigation. It has been suggested that this may be due at least in part to competing time, family and financial obligations, which increase over time.     

弹性抗阻运动对慢性阻塞性肺疾病康复疗效的Meta分析

目的 系统评价弹性抗阻运动(弹力带/弹力管)对慢性阻塞性肺疾病(COPD)患者康复疗效的影响。方法 检索Cochrane Library、PubMed、Web of Science、中国知网、维普、万方和生物医学文献数据库中关于弹性抗阻运动治疗COPD患者的临床随机对照试验,检索时限自建库至2020年9月。最后纳入文献11篇,其中英文9篇,中文2篇,共485例患者。采用Cochrane风险偏倚评估工具及物理治疗证据数据库量表进行质量评价,采用RevMan 5.2软件进行分析。这一系统评价在PROSPERO(CRD42020208659)上登记。结果 弹性抗阻运动组与传统抗阻运动组(如举重训练机、体重训练) 6 min步行试验距离(6WMD) (MD = 1.19, 95%CI -7.02~9.39, P = 0.78)、COPD患者自我评估测试(CAT) (MD = -0.43, 95%CI -2.42~1.57, P = 0.68)和肌力(MD = 0.23, 95%CI -1.06~1.52, P = 0.73)无显著性差异,两组间异质性不高。弹性抗阻运动组与非抗阻运动组6MWD (MD = 18.30, 95%CI -8.92~45.52, P = 0.19)和CAT (MD = -0.59, 95%CI -3.78~2.60, P = 0.72)无显著性差异,研究间异质性较高。结论 弹性抗阻运动也许是一种潜在的替代传统抗阻训练的方法,但弹性抗阻运动对运动耐力、生活质量、肺功能的影响尚不明确。
