Electronic clinical records in primary care for estimating disease burden and management. An example of COPD

Chronic obstructive pulmonary disease (COPD) is a significant health problem in developed countries. We aimed to estimate the prevalence of COPD in a single Spanish healthcare area. We also aimed to assess if there are any differences in prevalence and spirometry use among primary care services by utilizing already registered information. We designed a cross-sectional study to determine the prevalence of COPD and the performance of spirometries in each primary care service. A total of 8,444 patients were diagnosed with COPD, with a prevalence of 2.6% for individuals older than 39 years. The prevalence increased with age and was much higher in men. Significant heterogeneity was found in the prevalence of COPD and spirometry use among primary care services. COPD was underdiagnosed and there was wide variability in spirometry use in our area. Greater efforts are needed to diagnose COPD in order to improve its clinical outcomes and to refine registries so that they can be used as reliable sources of information     

Voluntary ambulation using voluntary upper limb muscle activity and Hybrid Assistive Limb® (HAL®) in a patient with complete paraplegia due to chronic spinal cord injury: A case report

Context: We sought to describe our experience with the Hybrid Assistive Limb® (HAL®) for active knee extension and voluntary ambulation with remaining muscle activity in a patient with complete paraplegia after spinal cord injury.

Findings: A 30-year-old man with complete paraplegia used the HAL® for 1 month (10 sessions) using his remaining muscle activity, including hip flexor and upper limb activity. Electromyography was used to evaluate muscle activity of the gluteus maximus, tensor fascia lata, quadriceps femoris, and hamstring muscles in synchronization with the Vicon motion capture system. A HAL® session included a knee extension session with the hip flexor and voluntary gait with upper limb activity. After using the HAL® for one month, the patient’s manual muscle hip flexor scores improved from 1/5 to 2/5 for the right and from 2/5 to 3/5 for the left knee, and from 0/5 to 1/5 for the extension of both knees.

Conclusion/clinical relevance: Knee extension sessions with HAL®, and hip flexor and upper-limb-triggered HAL® ambulation seem a safe and feasible option in a patient with complete paraplegia due to spinal cord injury.     

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.     

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。

目的 探讨老年慢性病患者常见症状间的相互关系及其对生存质量的影响,以寻找提高其生存质量的护理对策.方法 采用焦虑自评量表、老年人抑郁量表、SF-36量表对230例老年慢性病患者进行常见症状及生存质量调查,并分析各种症状间的关系以及症状与生存质量的相关性.结果 老年慢性病患者生存质量八大项目得分偏低.常见躯体症状包括躯体疼痛、头晕、疲乏、睡眠障碍发生率依次为25.73%、33.80%、25.00%、22.05%.常见心理症状焦虑和抑郁得分为38.35±7.26、8.71±5.21.且各种常见症状之间呈正相关(r=0.80～0.612,P<0.05),各种常见症状与生存质量呈负相关(r=-0.175～-0.623,P<0.05).结论 在老年慢性病患者居家护理过程中,须及时采取积极有效护理措施控制或减轻病人症状,且躯体症状护理与心理护理应并重,措施实施与原因排查应同步,主要症状与次要症状要兼顾,以提高其生存质量.     

Immunohistological identification of cell subsets in human gingival after local treatment for gingivitis or periodontitis

The cellular infiltrate present in human diseased gingiva was analyzed in biopsies from 12 patients with gingivitis or periodontitis. The samples studied had been obtained in the course of surgery at inflammatory sites remaining after institution of periodontal treatment. Histological and immunological techniques were used to identify macrophages, B-cells, plasma-cells, T-cells and T cell subsets, as well as cells expressing class II HLA membrane antigens. T-cells appeared as the predominant population, but plasma-cells were also visualized in nearly all samples. Both OKT4+ and OKT8+ cells were seen in all cases, the latter being more numerous in periodontitis patients. Interdigitating-like cells were observed, positively labelled for class II antigens, as well as macrophages which were more numerous in periodontitis patients. These results suggest the participation of all components of the immune response in gingival disease, in a way resembling chronic recurrent inflammatory diseases.     

Chronic lymphocytic leukaemia and lymphoma in an Iranian fat-tailed sheep: a case report

A 5-year-old Iranian fat-tailed sheep was referred to the Veterinary Clinic of Shiraz University in September 2003 with a history of emaciation, fever, decreased appetite, lethargy and cough. Small cutaneous and subcutaneous nodules were palpable, especially under the ribs on both sides of the thorax. Discrete cutaneous plaques and large scabby lesions were also observed. Very large mammary gland lymph nodes were noticed on palpation. Haematological and serum biochemical values were estimated through standard haematological and biochemical techniques. In this case a normocytic–normochromic anaemia, leukocytosis and lymphocytosis were found. The concentrations of blood urea nitrogen (BUN), creatinine, cholesterol and the activities of aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) were higher than the values reported for sheep. Necropsy findings revealed that the lymph nodes were affected in most organs. Malignant lymphoma in the kidney, heart, spleen, mammary glands, liver and bone marrow was observed. The histopathological appearance of the affected tissues varied considerably, depending upon the degree of tumour infiltration. According to the history, clinical signs, laboratory findings, necropsy findings and histopathological examination the case was diagnosed as chronic lymphocytic leukaemia and lymphoma.
