The purpose of this pilot study was to determine the impact of time of day on the acute response to incremental exercise in chronic obstructive pulmonary disease (COPD). Fourteen subjects (nine men) aged 71 ± 7 years with moderate to severe airflow obstruction (FEV1: 58 ± 13% predicted) followed a counterbalanced randomized design, performing three symptom-limited incremental cycling tests at 8:00, 12:00, and 16:00 hours on different days, each preceded by a spirometry. COPD medications were withdrawn prior to testing. No overall time effect was found for peak exercise capacity ( p = 0.22) or pulmonary function (FEV1, p = 0.56; FVC, p = 0.79). However, a large effect size ( f = 0.48) was observed for peak exercise capacity and several pulmonary function parameters. For peak exercise capacity, the average within-subject coefficient of variation was 5.5 ± 3.9% and the average amplitude of change was 7 ± 5W. Seven subjects (50%) showed diurnal changes at levels equal to or beyond the minimal clinically important difference for both peak exercise capacity and pulmonary function. In this sub-group, peak exercise capacity was greatest at 16:00 hours ( p = 0.03, ƒ = 1.04). No systematic time-of-day effect on peak exercise capacity was obtained in COPD patients in the present pilot study. However, based on the observed effect size and on the average amplitude of change and within-subject variations seen across testing times, the guidelines recommendation that time of day be standardized for repeat exercise testing in COPD should be maintained.

Background: Exacerbations are common in chronic obstructive pulmonary disease (COPD) and contribute significantly to COPD morbidity and mortality. COPD is also associated with high levels of psychological distress, which has been shown to be associated with higher exacerbation rates. However, the existing literature on the association between psychological distress and exacerbation risk remains largely misunderstood.Objectives: To critically review the current literature on the association between psychological distress (defined as anxiety and depressive symptoms or anxiety and depressive disorders) and COPD exacerbations in COPD patients, to highlight the limitations of the existing literature, and to provide recommendations for future research.Methods: A critical review of English-language peer-reviewed longitudinal and retrospective studies was conducted. The Ovid portal to Medline, EMBASE, and PsycINFO databases were accessed.Results: Some acceptable evidence suggested that psychological distress confers greater risk for exacerbations, more specifically symptom-based exacerbations or those treated in the patient’s own environment. However, most studies showed an absence of a positive association, especially with exacerbations leading to hospitalization.Conclusions: Methodological weaknesses and the use of a wide range of psychological tools mean that there is an inconsistent association between psychological distress and exacerbations in the current literature. However, psychological distress may confer greater risk for symptom-based rather than event-based defined exacerbations. Further studies are needed to more comprehensively assess the question, particularly in light of the high levels of both anxiety and depression in COPD patients. [ABSTRACT FROM PUBLISHER]

Social policies determine the distribution of factors (e.g. education, cardiovascular health) protecting against the development of dementia in Alzheimer’s disease (AD). However, the association between social policies and the likelihood of AD without dementia (ADw/oD) has yet to be evaluated. We estimated this association in an ecological study using systematic review and meta-analysis. Four reference databases were consulted; 18 studies were included in the final analysis. ADw/oD was defined as death without dementia in people with clinically significant AD brain pathology. The indicators of social policy were extracted from the Organisation for Economic Co-operation and Development database (OECD). The probability of ADw/oD with moderate AD brain pathology was inversely associated with the Gini index for disposable income, poverty rate, and certain public expenditures on healthcare. ADw/oD with advanced AD brain pathology was only associated with public expenditures for long-term care. Social policies may play a role in maintaining and sustaining cognitive health among older people with AD. [ABSTRACT FROM AUTHOR]

Background: People living in precarious socio-economic conditions are at greater risk of developing mental and physical health disorders, and of having complex needs. This places them at risk of health inequity. Addressing social determinants of health (SDH) can contribute to reducing this inequity. Case management in primary care is an integrated care approach which could be an opportunity to better address SDH. The aim of this study is to better understand how case management in primary care may address the SDH of people with complex needs., Methods: A case management program (CMP) for people with complex needs was implemented in four urban primary care clinics. A qualitative study was conducted with semi-structured interviews and a focus group with key informants (n = 24). An inductive thematic analysis was carried out to identify emerging themes., Results: Primary care case managers were well-positioned to provide a holistic evaluation of the person's situation, to develop trust with them, and to act as their advocates. These actions helped case managers to better address individuals' unmet social needs (e.g., poor housing, social isolation, difficulty affording transportation, food, medication, etc.). Creating partnerships with the community (e.g., streetworkers) improved the capacity in assisting people with housing relocation, access to transportation, and access to care. Assuming people provide their consent, involving a significant relative or member of their community in an individualized services plan could support people in addressing their social needs., Conclusions: Case management in primary care may better address SDH and improve health equity by developing a trusting relationship with people with complex needs, improving interdisciplinary and intersectoral collaboration and social support. Future research should explore ways to enhance partnerships between primary care and community organizations., (© 2024. The Author(s).)

Introduction Et Objectif: Une réponse efficace aux crises sanitaires telle la maladie à virus Ebola (MVE) nécessite l'engagement des communautés. Cette étude explore les enjeux psychosociaux influant sur la réponse des communautés congolaises aux épidémies de MVE, et comment la détresse et la résilience communautaire s'intègrent dans l'approche « Une seule santé » selon les perceptions des communautés., Méthodes: Cette étude de cas qualitative inclut des entretiens individuels ( n = 36) avec des informateurs clés et trois groupes de discussion avec des participants ( n = 28) issus de diverses associations locales, Cette étude de cas qualitative menée au Nord-Kivu inclut. Le cadre MATCH de l'engagement communautaire, adapté, structure l'analyse thématique., Résultats: Les participants ont tous reconnu le vécu douloureux - la peur, le rejet, la stigmatisation - des communautés et des professionnels de santé, et le rôle crucial des communautés dans la réponse aux épidémies. Ils ont souligné l'importance d'impliquer ces communautés dans l'élaboration et la mise en œuvre des stratégies pour éviter l'« Ebola business ». Les perceptions face à la maladie des différentes catégories de participants sont influencées par des croyances, les rôles sociaux et des considérations religieuses. Concernant l'approche « Une seule santé », les participants ont reconnu la nécessité d'impliquer toutes les couches sociales de la communauté., Conclusion: Un modèle innovant de gestion des épidémies et urgences de santé publique intègre les essentiels de l'engagement communautaire dont la détresse psychologique., Competing Interests: Conflit d’intérêtsAucun conflit d’intérêts déclaré.

The true extent of school bullying among youth with autism spectrum disorders (ASD) remains an underexplored area. The purpose of this meta-analysis is to: (a) assess the proportion of school-aged youth with ASD involved in school bullying as perpetrators, victims or both; (b) examine whether the observed prevalence estimates vary when different sources of heterogeneity related to the participants' characteristics and to the assessment methods are considered; and (c) compare the risk of school bullying between youth with ASD and their typically developing (TD) peers. A systematic literature search was performed and 17 studies met the inclusion criteria. The resulting pooled prevalence estimate for general school bullying perpetration, victimization and both was 10%, 44%, and 16%, respectively. Pooled prevalence was also estimated for physical, verbal, and relational school victimization and was 33%, 50%, and 31%, respectively. Moreover, subgroup analyses showed significant variations in the pooled prevalence by geographic location, school setting, information source, type of measures, assessment time frame, and bullying frequency criterion. Finally, school-aged youth with ASD were found to be at greater risk of school victimization in general, as well as verbal bullying, than their TD peers.

Little is known about the potential synergistic effect of comorbid psychological distress (PD) and uncontrolled asthma (UA) on productivity loss. We estimated the productivity loss associated with the combination of these two potentially preventable conditions in employed adults with asthma. A population-based random sample of 300 adults with asthma in British Columbia, Canada, was prospectively recruited between Dec 2010 and Aug 2012. PD and productivity loss due to absenteeism and presenteeism was measured using validated instruments, and asthma control was ascertained using 2010 Global Initiative for Asthma management strategy. We used two-part regression models to study the contribution of UA and PD to productivity loss. Compared with reference group (controlled asthma (CA)+noPD), those with UA+noPD had CAD$286 (95%CI $276-297) weekly productivity loss, and those with CA+PD had CAD$465 ($445-485). Those with UA+PD had CAD$449 (437-462) in productivity loss. There was no significant interaction effect of PD with asthma control levels on productivity loss (p=0.22). In patients without PD, uncontrolled asthma was associated with a higher productivity loss than controlled asthma, but this was not the case in patients with PD. This finding can be explained by the fact that the contribution of PD to productivity loss is so large that there is no room for synergy with asthma control. Future studies should assess the impact of interventions that modify PD in patients with asthma., (Copyright ©ERS 2015.)
