Continuous and online analysis of heart rate variability

Spectral analysis of heart rate variability provides a probe to assess the function of the sympathetic and parasympathetic nervous systems. Time-frequency analysis of heart rate variability is useful for investigating autonomic nervous function in patients with syncope or non-sustained ventricular tachycardia, or in anaesthesia, etc. In this paper, we developed an algorithm for continuous and online analysis of heart rate variability. The algorithm was simulated and evaluated in MATLAB, and implemented on the digital signal processor. The electrocardiogram signals from MIT/BIH arrhythmia database and one patient with syncope demonstrate the capability of the proposed method in the continuous and online analysis of heart rate variability.     

Neighborhood walkability,physical activity and changes in glycemic markers in people with type 2 diabetes: The Hoorn Diabetes Care System cohort

Studies investigating neighborhood walkability and physical activity in people with type 2 diabetes (T2D) mainly used self-report measures, and only few studies assessed the association with glycemic control. This study assessed the associations between objectively measured (i.e. GIS based) and subjectively measured (i.e. questionnaire-based) neighborhood walkability and changes in glycemic markers in people with T2D, and whether this association was mediated by device-measured physical activity (PA), in the Diabetes Care System Cohort (n = 1230). Neither objective or subjectively measured walkability was associated with glycemic control. In mediation analyses we observed no overall mediation by PA.     

Longitudinal person-centered measurement: A psychometric evaluation of the Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ)

ObjectiveThe Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ) was previously developed in Swedish to assess patients’ knowledge seeking and sense making capabilities. Aiming to measure preparedness at different phases during the pre-surgery and recovery period, the objectives were to (a) evaluate psychometric properties of the longitudinal PCSQ, (b) establish measurement invariance over time, and (c) describe change in preparedness.MethodsElective colorectal cancer surgery patients completed a questionnaire at five time points from pre-surgery until 6 months post-surgery (n = 250). The longitudinal PCSQ consists of 23 items measuring four domains: Searching for and making use of information, Understanding and involvement in care, Making sense of recovery, Support and access to care. Psychometric analyses, including confirmatory factor analysis, were applied to evaluate internal consistency reliability and ascertain invariance over time of the measurement structure and parameters.ResultsThe psychometric analyses revealed good fit of the measurement models, high internal consistency reliability (≥.94), and support for configural, metric and scalar measurement invariance of the four PCSQ domains. Patients reported lower levels of preparedness after surgery than pre-surgery.ConclusionThe adapted version of the PCSQ can be used for longitudinal analyses.Practice implicationsThe measurement of preparedness is important for evaluating person-centred outcomes before and during recovery from colorectal cancer surgery.

针对性护理模式对冠心病心绞痛患者心率血压及心理状态的影响分析

目的 探讨针对性护理模式在冠心病心绞痛患者临床治疗中的应用效果,结合患者的心率血压及心理状态变化情况进行评价。方法 选取解放军东部战区总医院心血管内科2019年2月至2020年2月期间收治的74例冠心病心绞痛患者作为研究对象,应用随机数字表法,分为观察组37例,进行针对性护理模式,对照组37例,进行常规护理,对比两组患者的护理效果。结果 与对照组相比,观察组患者在护理后的心率(HR)水平[(76.17±4.82)次/min vs.(80.62±3.94)次/min]、收缩压(SBP)水平[(134.42±10.25)mmHg vs.(143.57±11.94)mmHg]、舒张压(DBP)水平[(88.92±7.63)mmHg vs.(44.73±5.05)mmHg]、心绞痛发作频次[(0.52±0.13)次/周vs.(1.47±0.31)次/周]以及焦虑自评量表(SAS)评分[(38.14±4.37)分vs.(93.71±5.09)分]相对更低(P0.05),与对照比,观察组患者的护理满意度相对更高(P0.05)。结论 冠心病心绞痛患者的治疗恢复期间,针对性护理模式的应用,可以有效纠正患者的心率、血压异常,同时改善其心理状态,减少症状的发作,改善患者的预后。
