Daily stress and anxiety and their relation to daily fluctuations of symptoms in asthma and chronic obstructive pulmonary disease (COPD) patients

Although stress and anxiety have long been assumed to play an exacerbatory role in asthma, no study has systematically documented that daily exacerbations of asthma symptoms are related to stress and/or anxiety. In this study, 24 airways obstruction patients (12 asthmatics and 12 chronic obstructive pulmonary disease patients) were instructed to monitor the severity of daily respiratory symptoms. In addition, subjects recorded their daily anxiety level and the number and perceived impact of daily stressors. The results showed that although there were differences between high- and low-stress days for both groups, there were no differences between groups on symptom severity or between high- and low-anxiety days, as measured by the State-Trait Anxiety Inventory (STAI). Thus, although the number and impact of daily stressors were found to be directly associated with the severity of asthma symptoms, anxiety does not appear to have a direct role in the exacerbation of asthma. The findings failed to support the anxiety theory of asthma but provided an explanation for the poor results obtained in previous treatment studies which employed anxiety management with asthmatics.     

活动性肺结核患者生活废弃物处理现状研究

了解居家治疗的活动性肺结核患者生活废弃物的处理现状及认知态度.本研究采用多阶段随机抽样方法,选取720例居家治疗的活动性肺结核病患者,使用自制调查问卷进行回顾性调查,采用多因素回归对居家治疗活动性肺结核病患者生活废弃物处理的影响因素进行分析.研究发现超过半数患者对生活废弃物处理持积极态度,但仅有19.6％的患者能正确处理生活废弃物.Logistic回归分析发现患者对生活废弃物处理的态度、对督导态度以及是否有专人督导是能否正确处理生活废弃物的影响因素.因此,对患者普及生活废弃物处理的意义及方法,加强对患者督导有助于改善居家治疗活动性肺结核病患者生活废弃处理现状,对于预防结核病传播、实施遏制结核病策略具有重要意义.     

Effects of telephone support on exercise capacity and quality of life in patients with chronic obstructive pulmonary disease: a meta-analysis

The aim of this meta-analysis was to evaluate the effects of disease education or pulmonary rehabilitation programs assisted with telephone support on physical capacity and quality of life (QOL) in chronic obstructive pulmonary disease (COPD) patients. A systematic search of PubMed, Embase, Web of Science and The Cochrane Library was conducted until May 2017. Randomized controlled trials (RCTs) examining the effects of telephone-assisted intervention versus a control group on exercise tolerance and QOL in patients with COPD were included. Two independent authors assessed the methodological quality of the trials using the Cochrane risk of bias tool. A meta-analysis was conducted with the Revman5.3 to quantify the effects of telephone-assisted interventions on walking capacity and QOL. In total, 10 studies involving 1037 participants were included. Due to the effect of telephone-assisted interventions, statistically significant results were found on Saint-George’s Respiratory Questionnaire (SGRQ) symptom scores [standard mean difference (SMD) ?.18, 95% confidence interval (CI) ?.33, ?.03, p-value .02)], SGRQ impact scores [SMD ?.35, 95% CI ?.60, ?.10, p-value .006)], SGRQ activity scores [SMD ?.30, 95% CI ?.45, ?.15, p-value < .0001)], SGRQ total score [SMD ?.36, 95% CI ?.51, ?.21, p-value < .00001)]. The effects on 6-min walk test (6MWT) and all Chronic Respiratory Questionnaire (CRQ) subscales were not significant (p > .05) based on the insufficient evidence. In conclusion, the role of telephone-assisted interventions in the management of COPD remains equivocal. Some encouraging results were seen with regard to SGRQ symptom, SGRQ impact, SGRQ activity and SGRQ total score. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question.     

妊娠合并结核临床诊治的决策

妊娠合并结核是一种对母婴健康危害极大的妊娠期疾病。在妊娠期结核病中,多数患者无明显症状,早期症状与妊娠期某些生理反应相似,加之妊娠与结核病的相互影响,x线、CT等重要的影像学检查受限,致使本病易被误诊或误治。某些抗结核药物对母婴的不良影响,使其治疗难以实施,由于结核病本身及治疗后可能对胎儿的影响,在临床上是否终止妊娠往往难以决策。本文就妊娠合并结核诊治过程中的相关问题进行综述,以期为临床诊治决策提供帮助。     

Tuberculosis detection by giant african pouched rats

In recent years, operant discrimination training procedures have been used to teach giant African pouched rats to detect tuberculosis (TB) in human sputum samples. This article summarizes how the rats are trained and used operationally, as well as their performance in studies published to date. Available data suggest that pouched rats, which can evaluate many samples quickly, are sufficiently accurate in detecting TB to merit further investigation as a diagnostic tool.     

耐多药肺结核患者首次就诊过程调查

了解现阶段耐多药肺结核患者的首次就诊过程,分析医患双方对耐多药肺结核患者就诊过程的影响。在全国选取5个项目市,使用自制调查问卷采取面对面方式对样本人群进行访谈式调查。耐多药肺结核患者以文化水平较低、年龄偏大的农民为主。32.6%的患者初次就诊时有全身乏力或消瘦症状,37.6%的患者初次就诊单位为村卫生室或乡镇卫生院,28.4%的患者初次就诊时被误诊,31.6%的患者发生就诊延迟,79.8%的患者在结核病专科医院或防治机构确诊,33.3%的患者确诊延迟。加大对群众结核病相关知识宣传力度,加强结核病防治机构技术力量尤其是实验室诊断技术,加强对参与结核病防治工作医生尤其是村医的专业培训,针对医疗机构转诊建立适当的激励机制。     

慢性房颤导管消融策略的原则和个体化治疗

目前,慢性房颤导管消融的成功率及复发率均不尽人意。由于缺乏统一术式,慢性房颤消融采用的是肺静脉隔离、电图靶向消融及线性消融等多术式综合策略。在房颤消融策略上,既要坚持肺静脉电隔离原则,又要体现消融术式选择和实施的个体化,阶梯消融综合术式的推出就是这种思维方法的具体运用。     

经皮肺活检对肺部病变的诊断价值

结核患者服药依从性的研究现状

结核病控制是全球卫生工作的一个重点,服药依从性则是其中关键的一环。本文对结核患者服药依从性的重要性、影响因素及提高依从性的措施进行综述,认为实施直接督导短程化疗（DOTS）、强化督导、改善患者对服药依从性的认识、简化给药方案、减轻患者经济负担、设置患者提醒物等可提高服药依从性。
