The Relationship between Self-Efficacy,Functional Exercise Capacity and Physical Activity in People with COPD: A Systematic Review and Meta-Analyses

Abstract

The purpose of this study was to investigate the strength of the relationships between self-efficacy and (i) functional exercise capacity and (ii) physical activity in chronic obstructive pulmonary disease (COPD), and whether self-efficacy assessment type (i.e., COPD symptoms, exercise-task, exercise-barrier, general, falls) and physical activity assessment type (i.e., self-report vs. objective) are moderators. A systematic search of COPD and self-efficacy concepts was conducted using eight databases from inception to 23 January 2019. Studies were included if they provided correlation coefficients of the relationship between self-efficacy and functional exercise capacity or physical activity, were conducted in adults diagnosed with COPD, and were published in English-language journals. A total of 14 correlation coefficients were included in the self-efficacy and functional exercise capacity meta-analysis, and 16 in the self-efficacy and physical activity meta-analysis. Data were screened, reviewed, and extracted independently by two reviewers, with discrepancies resolved by a third reviewer. Stronger self-efficacy was associated with better functional exercise capacity (weighted r?=?0.38, 95%CI [0.25, 0.50]), and greater physical activity (weighted r?=?0.25, 95%CI [0.17, 0.34]). Exercise-task self-efficacy had the strongest relationship to functional exercise capacity (weighted r?=?0.64, 95% CI [0.51, 0.73]). For physical activity, the type of self-efficacy most strongly related was inconclusive. In COPD, self-efficacy has a relationship to functional exercise capacity and physical activity, the strength of which is influenced by the choice of self-efficacy measure. An understanding of these relationships will assist clinicians in selecting the self-efficacy measure most closely related to the outcome of interest.

Differential diagnosis of leg ulcers

In Germany about 0.7 % of the adult population have a chronic leg ulcer. Although chronic venous insufficiency accounts for at least 80 % of all chronic leg ulcers, knowledge of the relevant differential diagnostic considerations is of crucial importance, in particular for patients who are refractory to therapy. In addition to vascular disease, other causes include neuropathic, metabolic, hematologic and exogenous factors as well as neoplasias, infections, drugs, genetic defects and some primary skin disorders. For the long‐term successful treatment of patients with chronic leg ulcers, it is necessary to identify all relevant factors, in order to enable a pathogenesis‐oriented, interdisciplinary therapeutic approach.     

延边地区农村朝、汉族肥胖与慢性病危险因素关系分析

目的：分析延边农村地区朝、汉族肥胖与慢性病危险因素关系。方法：随机抽取延边地区农村50～60岁朝、汉族常驻人群447名，采用面对面询问法进行问卷调查，观察不同民族体质指数（BMI）、腰围（WC）水平与慢性病危险因素-血清总胆固醇（TC）、高密度脂蛋白胆固醇（HDI—C）、甘油三醋（TG）、收缩压（SBP）、舒张压（DBP）及血糖（FBG）的关系。结果：不同民族居民WC、SBP、DBP、FBG及HDL—C分布特征存在差异。不同民族BMI、WC与慢性病危险因素的相关性存在差异。结论：制定延边地区慢性病防治策略和措施时应考虑民族与肥胖种类的因素。     

慢性肾衰竭急性加重的临床特征及相关因素分析

目的：探讨慢性肾衰竭（CRF）急性加重因素及其治疗措施对预后的影响。方法：对2001年1月～2005年6月住院治疗的CRF急性加重患者42例，按其加重原因、基础疾病、治疗方式和疗效进行回顾性总结。结果：CRF急性加重因素依次为各种感染（45．2％）、原发病加重（19．0％）、高血压未控制（14．3％）、水电解质紊乱（11．9％）、肾毒性药物（11．9％）、心功能不全（9．5％）、尿路梗阻（4．8％）、血高粘滞状态（2．4%），7例同时存在≥2种上述病因（16．7％）。CRF急性加重原发病以慢性肾小球肾炎（52．4％）和糖尿病肾病（11．9％）为主。积极治疗后肾功能恢复达到或接近原来水平者40例，死亡2例，死亡2例的年龄均在60岁以上。结论：对于CRF肾功能急剧恶化的患者，应积极寻找其加重因素，并采取非透析和透析相结合治疗，改善肾功能，降低病死率，延长患者生命。

Discrimination of idiopathic pain syndromes from neurogenic pain syndromes and healthy volunteers by means of clinical rating,personality traits,monoamine metabolites in CSF,serum cortisol,platelet MAO and urinary melatonin

Summary The aim of the present study was to investigate the discriminative power of a series of variables (including determination of depressive symptomatology by means of a visual analogue scale, determination of personality traits by means of the Karolinska Scales of Personality, determination of monoamine metabolites in CSF, platelet MAO activities, serum cortisol before and after dexamethasone suppression and urinary melatonin) in differentiating (a) chronic pain patients from healthy subjects, and (b) patients with idiopathic pain syndromes from patients with neurogenic pain syndromes. Separately each of the measures gave a significant but often low contribution to the discrimination, while a combination of several measures gave a complete discrimination both between healthy subjects and patients with chronic pain syndromes and between patients with idiopathic and neurogenic pain syndromes, respectively.Supported in part by grants from the Swedish Medical Research Council (grants no. 3371, 4145 and 5740) and by a grant from Stiftelsen Söderström-Königska Sjukhemmet
