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.     

Emotion suppression and reappraisal associated with bullying involvement and other social outcomes in young adults

The ability to regulate emotions appropriately and effectively is important in maintaining positive social interactions and outcomes. The current study investigated the association between the habitual use of suppression and reappraisal, and involvement in bullying in high school. Other social outcomes, such as current social satisfaction and support, were also considered. Two hundred and nine first-year psychology university students (mean age 19.13 years, SD?=?1.523) completed online questionnaires. Results demonstrated that suppression was associated with greater retrospective reports of victimisation during high school and lower current social satisfaction and support, even when controlling for general affect. Reappraisal was mostly found to be unrelated to bullying and social outcomes, with only one association existing between higher reappraisal use and better social satisfaction, which was no longer significant when controlling for affect. The findings extend on previous research by demonstrating a negative association between suppression and involvement in bullying.     

Health-Related Quality of Life in a Low-Socioeconomic Status Public Rental-Flat Population in Singapore

Health-related quality of life (HRQoL) is a well-established measure of health and general well-being. Socioeconomic status (SES) can affect HRQoL. We sought to determine whether there were differences in HRQoL between low versus higher area-SES flat communities in Singapore. Residents in two integrated public housing precincts comprising of rental-flat blocks (low area-SES neighborhood) and neighboring owner-occupied blocks (higher area-SES neighborhood) were asked to rate their self-perceived HRQoL using the EuroQol Group five dimensions (EQ-5D) instrument. The EQ-5D assesses HRQoL in five domains (mobility, self-care, usual activities, anxiety/mood and pain) and with a global visual analogue scale (EQ-VAS). We evaluated differences in HRQoL between the rental and owner-occupied neighborhoods, and factors associated with anxiety/depression in the rental-flat neighborhood using multivariate logistic regression. The participation rate was 89.1% (634/711). In the owner-occupied neighborhood, 56.7% (216/381) were in full health, compared with 54.2% (137/253) in the rental-flat population (OR = 0.90, 95%CI = 0.66–1.24, p = 0.568). Across the five domains, staying in a rental-flat neighborhood was independently associated with anxiety/depression (adjusted odds ratio [aOR] = 1.79, 95%CI = 1.10–2.92, p = 0.019). In the rental-flat population, having anxiety/depression was independently associated with minority ethnicity, problems with self –care, pain/discomfort, difficulty with healthcare costs, and not being on subsidized primary care (p < 0.05). There was no significant difference on the EQ-VAS between the two neighborhoods (p = 0.627). Staying in a low area-SES neighborhood was associated with more mental health problems. In the rental-flat population, self-reported anxiety/depression was associated with minority ethnicity, physical health problems, and financial disadvantage in healthcare.     

“集体主义—个体主义”的差异:来自基因、大脑的证据

文章以"集体主义—个体主义"这一基本文化差异维度为基础,围绕文化、基因和大脑之间的关系,介绍了国内外最新研究进展。研究显示当人类执行各种文化任务时,那些为人类生存提供有力帮助的基因会被选择和保留下来;在自我表征,注意和知觉,决策、情绪和意向推断等心理状态或过程上的"集体主义—个体主义"文化差异都可追溯到脑功能的差异。研究者先后提出社会脑假设、文化—基因协同进化论、神经—文化交互作用模型等理论来解释基因、文化与大脑交互作用的现象。文章分析了当前研究中存在的问题,并对未来的研究进行了展望。     

艾滋病防控中获取患者信息的伦理问题刍议

当前艾滋病获取患者信息中,存在公私观念上的摩擦、相关规定与环节存在疏漏、对信息弱势群体关照不足的伦理难题。问题背后包含着患者为了公共健康的伦理目的却又失去伦理关系的风险,“失德”名声带来的耻感与歧视,遵守政策规范却缺少应有的尊重与保护等矛盾。问题的解决需要在文化背景和利益关系下思量个人身心秩序与社会整体秩序间如何权衡,结合历史、理论与现实维度提出路径。“信”的建立是关键所在,包括公共卫生部门公信力的树立和相应制度措施建设,同时在信息活动中需要给“私”以合理地位,并注重艾滋病治疗相关医学信息的宣传。     

Local and Global Sources of Control in Pigeon Delayed Matching-to-sample Performance

The present study employed a behavioural detection approach to investigate the combined effects of sample duration and sample presentation frequency on delayed matching accuracy of pigeons. Experiment 1 showed that when both samples were exposed at each of the two possible durations within a two-alternative, delayed matching session, discriminability was higher to the longer duration sample than to the short-duration sample, as found when sample duration is varied between sessions. Experiment 2's asymmetrical procedure increased bias toward the more frequent of the two samples but had no influence on discriminability. Initial discriminability was higher to samples exposed for longer durations, irrespective of stimulus presentation frequency. The results suggest qualitatively different effects of the two sources of stimulus control under consideration: Sample duration (a local or within-trial manipulation) exerted its effect on discrimination of the stimuli, whereas sample presentation frequence (a global factor) exerted its major effect on response bias. An interpretation of the data in terms of Blough's (1996) analysis of errors in matching tasks suggests that the amount of behaviour under control of the sample stimulus markedly changed with different sample durations. The analysis also showed that the biasing manipulation exerted most of its effect on the portion of behaviour outside of control by the critical stimulus. We argue that theoretical accounts of delayed matching performance need to consider both local and global factors as determinants of matching accuracy.     

Does Duration of Deregulated Religious Markets Affect Church Attendance? Evidence from 26 Religious Markets in Europe and North America Between 1981 and 2006

This study tests the deregulation hypothesis of religious market theory in 26 European and Northern American countries by examining differences in religious involvement between and within countries. The deregulation hypothesis, which is assumed to be universally valid, predicts that religious involvement is higher in deregulated religious markets. Moreover, countries having deregulated religious markets for a longer period of time are supposed to have higher levels of involvement. Therefore, we test the duration hypothesis. This test is important, as it also has been argued that it may take time for deregulation to have an effect on religious involvement. Multilevel analysis on the stacked European and World Value Surveys of 1981, 1990, 2000, and 2006 show that deregulation fosters church attendance, but duration of deregulation does not increase church attendance. Although the deregulation hypothesis cannot be rejected, we find that modernization corrodes church attendance to a larger extent than deregulation can stimulate church attendance.     

Creativity,Schizotypicality, and Mystical Experience: An Empirical Study

This study examined the commonalities and the differences between creativity and the schizophrenia spectrum. The variables measured were creativity, schizotypy, absorption, mystical experiences, spatial ability, balance, positive and negative presence, and neuroticism. Three community groups were recruited: 31 artists, 10 people with schizophrenia, and 31 comparisons matched for gender and age with the artists. A larger student group, consisting of 102 students, was also recruited to examine the correlations among the same variables within a larger, more normative, group. The largest commonality between the artist and the schizophrenic groups was the propensity to mystical experiences. The greatest differences between them were that the artists were higher in creativity, had better spatial ability, had better balance, had more positive states of presence, and were lower in neuroticism. In the student group, creativity was positively correlated with positive schizotypy, impulsive nonconformity, spatial ability, positive presence, absorption, and mystical experiences, although in the student group, the relation between creativity and mystical experiences was completely mediated by absorption.     

Overall Freedom and Constraint

McDowell's contributions to epistemology and philosophy of mind turn centrally on his defense of the Aristotelian concept of a “rational animal”. I argue here that a clarification of how McDowell uses this concept can make more explicit his distance from Davidson regarding the nature of the minds of non-rational animals. Close examination of his responses to Davidson and to Dennett shows that McDowell is implicitly committed to avoiding the following “false trichotomy”: that animals are not bearers of semantic content at all, that they are bearers of content in the same sense we are, and that they are bearer of “as if” content. Avoiding the false trichotomy requires that we understand non-rational animals as having concepts but not as making judgments. Furthermore, we need to supplement McDowell's distinction between the logical spaces of reasons and of the realm of law with what Finkelstein calls “the logical space of animate life”. Though McDowell has taken some recent steps to embrace a view like this, I urge a more demanding conception than what McDowell has thus far suggested.
