1401例超长住院日患者分布与影响因素分析

目的分析超长住院患者分布及影响因素,探讨减少超长住院日的措施。方法从江苏省某三甲医院病案管理系统中调取2020年1月1日-2020年12月31日134016例出院患者的住院病案首页资料,对住院时间≥30天的1401例超长住院患者的分布特征进行统计描述,采用Logistic回归模型分析超长住院日的影响因素。结果2020年全院平均住院日为7.13天,其中超长住院患者平均住院日为41.85天。超长住院患者以60岁以上年龄组最多(39.61%);出院科室主要分布在血液科(42.18%)、普通外科(11.85%)、骨科(7.49%)等;疾病类别主要为肿瘤(47.32%)、影响健康状态和与保健机构接触的因素(10.56%)、循环系统疾病(7.07%)等;多因素Logistic回归结果显示,男性(OR=1.188)、离院方式为非医嘱离院或其他(OR=2.046)和死亡病例(OR=3.362)是超长住院的危险因素。结论控制超长住院日对平均住院日影响显著,医院应加强重点人群、重点科室和重点病种管理提高诊疗管理水平,缩短平均住院日。     

The biomechanical effects of 3D printed and traditionally made foot orthoses in individuals with unilateral plantar fasciopathy and flat feet

BackgroundFoot orthoses (FOs) are used to manage foot pathologies such as plantar fasciopathy. 3D printed custom-made FOs are increasingly being manufactured. Although these 3D-printed FOs look like traditionally heat-moulded FOs, there are few studies comparing FOs made using these two different manufacturing processes.Research questionHow effective are 3D-printed FOs (3D-Print) compared to traditionally-made (Traditional) or no FOs (Control), in changing biomechanical parameters of flat-footed individuals with unilateral plantar fasciopathy?MethodsThirteen participants with unilateral plantar fasciopathy walked with shoes under three conditions: Control, 3D-print, and Traditional. 2 × 3 repeated measures analysis of variance (ANOVAs) with Bonferroni post-hoc tests were used to compare discrete kinematic and kinetic variables between limbs and conditions. Waveform analyses were also conducted using statistical parametric mapping (SPM).ResultsThere was a significant condition main effect for arch height drop (p = 0.01; ηp² =0.54). There was 0.87 mm (95% CI [−1.84, −0.20]) less arch height drop in 3D-print compared to Traditional. The SPM analyses revealed condition main effects on ankle moment (p < 0.001) and ankle power (p < 0.001). There were significant differences between control condition and both 3D-print and Traditional conditions. For ankle moment and power, there were no differences between 3D-print and Traditional conditions.Significance3D-printed FOs are more effective in reducing arch height drop, whist both FOs lowered ankle plantarflexion moment and power compared to no FOs. The results support the use of 3D-printed FOs as being equally effective as traditionally-made FOs in changing lower limb biomechanics for a population of flat-footed individuals with unilateral plantar fasciopathy.     

Visualizing changes in physical activity behavioral patterns after redesigning urban infrastructure

The aim of this study was to explore effects of a major urban reconstruction on physical activity (PA) behavior by comparing PA intensity hotspots before and after the tunneling of a highway with a new infrastructure prioritized for walking and cycling. In total, 126 individuals participated before and after the tunneling. GPS loggers and accelerometers were used to assess location and PA levels. A geographic information system (GIS) was used to perform optimized hotspot analyses on PA data, both on transport and stationary data points. The results showed several changes in PA hotspots on trip data, even if total PA levels did not change. At follow-up, PA intensity hotspots were more connected, with the new infrastructure as a central connection. This was true for higher and lower educated individuals. Therefore, if changes in the built environment do not result in changes on population-level outcomes, this does not imply that they have no impact on behavior.     

三种不同引流方式对食管癌术后颈部吻合口瘘引流效果的研究

目的:探讨三种不同引流方式对食管癌术后颈部吻合口瘘的引流效果。方法:收集从2013年1月到2016年9月在我科行食管癌手术并术后发生颈部吻合口瘘患者，比较入组患者所采用的不同颈部引流方式的优劣。结果:共有83例患者纳入研究，有34例进入A组，行纱布条引流组；28例进入B组，行造瘘袋引流组；21例进入C组，行胃管负压引流组。所有入组患者一般资料和手术资料对比无明显统计学差异（P>0.05）。观察指标对比结果显示，C组患者瘘口愈合时间较其他两组时间短［（15.90±4.18）天vs（14.60±4.41）天vs（9.65±3.80）天］，住院时间较其他两组短［（18.10±4.17）天vs（16.20±3.78）天vs（12.30±3.29）天］，换药次数较其他两组少［（37.55±8.75）天vs（14.5±3.23）天vs（10.00±2.05）天］，抗生素使用时间也较其他组明显减少［（13.10±2.49）天vs（10.85±1.84）天vs（7.20±1.74）天］。结论:颈部放置负压引流有助于食管癌术后颈部吻合口瘘愈合，值得临床推广与进一步研究。     

生物标志物的联合检测对矽肺早期辅助诊断的价值

目的：探讨联合检测生物标志物应用于矽肺早期辅助诊断的灵敏度和特异性。方法：采用立意抽样法，选取65例男性矽肺患者为病例组，以70例接触游离二氧化硅的在岗作业人员为对照组。清晨空腹采集外周血并分离血清，采用比色法测定对照人群和矽肺患者血清中超氧化物歧化酶（SOD）和丙二醛（MDA）水平；酶联免疫吸附法测定白细胞介素-6（IL-6）及肿瘤坏死因子-α（TNF-α）水平，以矽肺I期患者血清中有显著性变化的生物标志物（MDA、IL-6和TNF-α）检测数据为数据集，绘制受试者工作特征曲线（ROC）并建立Logistic回归模型，评估联合检测上述生物标志物对矽肺早期辅助诊断的价值。结果：与对照组相比，矽肺患者血清中SOD表达水平无显著变化（P > 0.05）；矽肺I期及Ⅱ期患者血清中MDA及IL-6表达水平显著升高（P < 0.05）；矽肺I期患者血清中TNF-α表达水平显著升高（P < 0.05）。回归模型结果显示，ROC曲线下面积排序为：3个指标联合检测（0.89） > IL-6（0.86） > MDA（0.81） > TNF-α（0.65）。结论：IL-6、TNF-α和MDA的联合检测可以提高矽肺早期辅助诊断的灵敏度和特异性。     

National level data analysis of facial lacerations in Korea using the National Health Insurance Service (NHIS) database

No national epidemiological investigations have been conducted recently regarding facial lacerations. The study was performed using the data of 3,634,229 people during the 5-year period from 2014 to 2018 archived by the National Health Information Database (NHID) of the Health Insurance Review and Assessment Service. Preschool and children under 10 years old accounted for about one-third of patients. Facial lacerations were concentrated in the “T-shaped” area, which comprised forehead, nose, lips, and the perioral area. The male to female ratio for all study subjects was 2.16:1. Age and gender are significantly related with each other (P < .001). Mean hospital stays decreased, and numbers of outpatient department visits per patient were highest for hospitals and lowest for health agencies. Over the study period, hospital costs per patient in tertiary and general hospitals increased gradually. Preschool and school-aged children are vulnerable to trauma. Male patients outnumbered female patients by a factor of more than 2. The “T-shaped’” area around forehead is vulnerable to injury. Total cost of medical care benefits per patient in tertiary hospitals was about 7 times on average than in health agencies. Regarding functional, behavioral, and aesthetic outcomes, more attention should be paid to epidemiologic data and hospital costs for facial lacerations.
