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。     

Adaptive treadmill walking encourages persistent propulsion

BackgroundAdaptive treadmills allow real-time changes in walking speed by responding to changes in step length, propulsion, or position on the treadmill. The stride-to-stride variability, or persistence, of stride time during overground, fixed-speed, and adaptive treadmill walking has been studied, but persistence of propulsion during adaptive treadmill walking remains unknown. Because increased propulsion is often a goal of post-stroke rehabilitation, knowledge of the stride-to-stride variability may aid rehabilitation protocol design.Research questionHow do spatiotemporal and propulsive gait variables vary from stride to stride during adaptive treadmill walking, and how do they compare to fixed-speed treadmill walking?MethodsEighteen young healthy subjects walked on an instrumented split-belt treadmill in the adaptive and fixed-speed modes for 10 minutes at their comfortable speed. Kinetic data was collected from the treadmill. Detrended fluctuation analysis was applied to the time series data. Shapiro-Wilk tests assessed normality and one-way repeated measures ANOVAs compared between adaptive, fixed-speed, and randomly shuffled conditions at a Bonferroni-corrected significance level of 0.0055.ResultsStride time, stride length, step length, and braking impulse were persistent (α > 0.5) in the adaptive and fixed-speed conditions. Adaptive and fixed-speed were different from each other. Stride speed was persistent in the adaptive condition and anti-persistent (α < 0.5) in the fixed-speed condition. Peak propulsive force, peak braking force, and propulsive impulse were persistent in the adaptive condition but not the fixed-speed condition (α ≈ 0.5). Net impulse was non-persistent in the adaptive and fixed-speed conditions. All variables were non-persistent in the shuffled condition.SignificanceDuring adaptive treadmill walking, increases in propulsive force and impulse persist for multiple strides. Persistence was stronger on the adaptive treadmill, where increased propulsion translates into increased walking speed. For post-stroke gait rehabilitation where increasing propulsion and speed are goals, the stronger persistence of adaptive treadmill walking may be beneficial.     

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.     

以就业为导向的脊柱相关疾病的推拿教学策略

河南省非订单定向全科住院医师规范化培训结业学员的就业状况及影响因素研究

背景 全科医生数量和质量是人力资源管理的两个重要维度，其中，医生数量的新增、保持和流失，是全科人力动态规划、管理和评价的重要考量，也是全科住院医师规范化培训（简称全科住培）的绩效指标。探讨全科住培学员的就业状况及影响因素，可以为今后住培政策和激励机制的制定提供参考，但目前针对非订单定向全科住培学员的相关研究较为缺乏。 目的 了解河南省非订单定向全科住培学员的就业状况，分析学员结业后未从事全科医学相关工作的原因，从而为完善培训管理和人力资源激励机制提供参考。 方法 于2021年8月，采用分层随机整群抽样法，在河南省选取2014—2017年入培且已结业的非订单定向全科住培学员326例进行问卷调查。问卷由课题组自行设计，主要内容为学员的基本信息、全科住培情况、目前工作情况及结业后从事与未从事全科医学相关工作的原因。问卷通过"问卷星"平台发放，由学员自行填写。 结果 共发放问卷326份，回收有效问卷271份（83.1%）。结业后，从事全科医学相关工作者77例（28.4%），从事非全科医学相关工作者194例（71.6%）。多因素Logistic回归分析结果显示，年龄、文化程度、生源类型、全科住培基地所在区域是学员结业后是否从事全科医学相关工作的影响因素（P<0.05）。与结业后未从事全科医学相关工作的学员相比，结业后从事全科医学相关工作学员注册为全科医学专业的比例更高〔70.1%（54/77）比32.0%（62/194），P<0.05〕，在乡镇卫生院/社区卫生服务中心执业的比例更高〔49.4%（38/77）比6.2%（12/194），P<0.05）〕。194例未从事全科医学相关工作的学员中，从事内科学工作者78例（40.2%），从事急诊及危重症医学工作者33例（17.0%），从事外科学工作者17例（8.8%）。不选择从事全科医学相关工作的前3位原因分别为：单位安排〔34.5%（67/194）〕，所在单位没有全科医学科〔29.9%（58/194）〕，薪酬低〔26.8%（52/194）〕。 结论 非订单定向全科住培学员选择从事全科医学相关工作的比例较低，年龄、文化程度、生源类型及基地所在区域是影响因素。建议加大全科医学理念宣传，加快综合医院全科医学科建设，提高全科医生薪酬待遇，以此增加全科医生的职业吸引力。     

Reporting radiographer academy training model; an evaluation of the impact for trainees and clinical service

IntroductionDemand on imaging services continues to increase on a background of complex issues and barriers to care. Collaborative cross organisational working through the development of imaging networks is recommended to address these issues including managing reporting workloads. Standardisation of reporting practices and collaborative cross region reporting radiographer training has been recommended to be supported by a regional reporting radiographer academy model to achieve these aims. This research explores the perceptions of trainees and their managers/mentor who undertook radiographer academy training model with a view to integrated imaging network formalisation in the region.MethodsAn online questionnaire was designed to capture qualitative and quantitative data with three phases; 1) trainees perception of the academy model, 2) trainees perception of the differences in training models and 3) the perceptions of the managers/mentors related to the academy model.ResultsThere were overwhelmingly positive opinions of the academy training model from both cohorts in this study, with the two main benefits emerging being the protected study time away from clinical departments and minimal disruption to clinical services due to reduced onus on the local mentors. Peer support was also highlighted as a positive aspect of the model which would facilitate future integrated imaging network working.ConclusionThe academy model has been well received by both cohorts in this study with positive outcomes highlighted and the model being seen as promoting and facilitating integrated imaging network working between departments. The small sample size of the study requires consideration when extrapolating the results to wider academy models, however some themes may be applicable.Implications for practiceInvestment in the reporting radiographer academy model is justified and provides a practical alternative to the traditional model.
