食管癌高、低发区食管鳞癌患者生存及其影响因素分析

目的 探讨食管癌高、低发区食管鳞癌患者的生存状况及其影响因素。方法 收集38 741例经病理学证实为食管鳞癌患者的资料，其中，高发区患者23 273例（60.1%），低发区15 468例（39.9%）。所有患者均行食管癌根治术。运用卡方检验分析不同临床病理特征患者的组间差异，Kaplan-Meier法绘制不同临床病理特征患者的生存曲线并用Log rank进行检验。多因素Cox比例风险回归模型法分析影响生存的主要因素。结果 低发区男性患者所占比例高于高发区（P<0.001），低发区诊断年龄≥50岁食管癌患者所占比例高于高发区（P<0.001）。高发区食管鳞癌患者的整体生存优于低发区患者（P<0.001）。Cox比例风险回归模型综合分析结果表明：高低发区、性别、确诊年龄、肿瘤部位、分化程度、TNM分期和肿瘤家族史均是影响食管鳞癌患者生存的独立因素。结论 高发区食管鳞癌患者整体生存优于低发区；低发区是食管鳞癌患者预后差的独立危险因素。     

万古霉素药物暴露量阈值与肾毒性的相关性分析

目的探讨万古霉素药物暴露量与肾毒性发生的相关性,并确定其上限阈值。方法前瞻性收集2018年5月-2019年1月接受静脉注射万古霉素治疗的成人住院患者信息。使用贝叶斯最大后验概率法计算药时曲线下面积(AUC)并采用分类和回归树(CART)的方法分析和确定万古霉素初始剂量及与肾毒性相关的稳态AUC阈值。通过受试者工作特征(ROC)曲线评估上述方法所得AUC阈值的预测性能及对万古霉素相关肾毒性的诊断价值,并采用多因素logistic回归分析量化肾毒性发生风险因素。结果共纳入患者155例,其中发生肾毒性患者13例(8.39%)。经CART分析得到AUC0-24、AUC24-48、AUCss0-24对肾毒性预测的最佳阈值点分别为622 mg·h/L、617 mg·h/L、578 mg·h/L。经多因素logistic回归分析,AUC超过最佳阈值点时肾毒性发生率显著提高(P≤0.01),联合使用肾毒性药物与肾毒性发生独立相关,会提高约6倍的肾毒性发生率(P<0.01)。结论万古霉素暴露量超过阈值时会大幅提高肾毒性发生风险,提示AUC监测对预测肾毒性发生有很高的临床价值。     

Comparison of dynamic occlusal contacts during chewing between children with primary dentition and normal adult females

ObjectiveInvestigation of dynamic occlusal contacts when food particles are being pulverized during chewing is of interest for many researchers and clinicians. However, measurement of dynamic occlusal contacts during chewing is difficult, and differences between children and adults have not been established. The purpose of this study is to test the hypothesis that dynamic occlusal contacts of children differ from those of adult females.Subjectsand methods: Thirteen healthy children (4–6 years of age; mean age 5 years, 7 months) and thirteen adult females (18–26 years of age; mean age 20 years, 7 months) with normal occlusion participated in this study. Occlusal contact area (OCA) was estimated with a developed measurement system combining 3-D digitization of tooth shape with 3-D tracking of mandibular movements (1) during the closing stroke, (2) at the maximum closing position (MCP), and (3) during the opening stroke. OCA at static maximum intercuspation (ICP) was also estimated.ResultsAt the MCP, the children's OCA was less than 76.4% of the contact area seen at the ICP. The timing of maximum OCA in children was shifted more towards the opening stroke compared with adults, and the OCA remained greater during opening in children than adults. The occurrence of the MCP was less stable in children than in adults, both between subjects and within subjects.ConclusionsWe conclude that both the amount of OCA and the pattern of occlusal contacts during the occlusal phase of chewing completely differ between children and adult females.     

Objective and subjective measures of the neighbourhood environment: Associations with frailty levels

ObjectivesThe aim of this study was to investigate whether perceptions of the neighbourhood environment (NE) and objective measures of the NE were associated with frailty in older adults.MethodsA cross-sectional study in Adelaide, Australia, recruited a sample of 115 community-dwelling adults aged ≥60 years. Respondents’ perceptions of their NEs were assessed using the Neighbourhood Environment Walkability Scale (NEWS). An objective assessment of these NEWS survey questions was conducted using seven variables: residential density, land use mix diversity, street connectivity, accessibility, seasonal persistent green cover, road crash density and crime rate. Frailty was evaluated using the FRAIL (fatigue, resistance, ambulation, illnesses and loss of weight) scale. Multivariable linear regression analyses were employed to assess the associations between NEWS and frailty, and to assess the associations between objective neighbourhood variables and frailty.ResultsFrail and pre-frail older adults were more likely to live in areas with lower residential density, lower density of road crashes, and higher accessibility than robust participants. Additionally, a poorer perception of the overall environment, worse land-use mix and accessibility and worse crime safety were associated with frailty and pre-frailty after adjustment of covariates and objective GIS variables.DiscussionNeighbourhood characteristics, both objective and perceived, are associated with frailty levels in older adults, and that strategies to tackle frailty must consider the impact of the neighbourhood environment.
