Exploring self-conscious emotions in individuals with chronic obstructive pulmonary disease:A mixed-methods study

This study aimed to explore the extent to which self-conscious emotions are expressed, to explore any associations with adverse health outcomes, and to compare self-conscious emotions in individuals with chronic obstructive pulmonary disease (COPD) to healthy controls. A two-stage mixed-methods study design was employed. Interviews with 15 individuals with COPD informed the choice of questionnaires to assess self-conscious emotions which were completed by individuals with COPD and healthy controls. Five overarching themes were abstracted: grief, spectrum of blame, concern about the view of others, concealment, and worry about the future. The questionnaires were completed by 70 patients (mean( SD) age 70.8(9.4) years, forced expiratory volume in one second predicted 40.5(18.8), 44% male) and 61 healthy controls (mean( SD) age 62.2(12.9) years, 34% male]. Self-conscious emotions were associated with reduced mastery, heightened emotions, and elevated anxiety and depression (all p &lt; 0.001). Individuals with COPD reported lower self-compassion, higher shame, and less pride than healthy controls (all p ≤ 0.01). There is a need to increase awareness of self-conscious emotions in individuals with COPD. Therapies to target such emotions may improve mastery, emotions, and psychological symptoms. </jats:p

Optimizing nonpharmacological management following an acute exacerbation of chronic obstructive pulmonary disease.

Samantha L Harrison,1 Roger Goldstein,1 Laura Desveaux,1 Verity Tulloch,1 Dina Brooks2 1Department of Respiratory Medicine, West Park Healthcare Centre, Toronto, ON, Canada; 2Department of Medicine Physical Therapy, University of Toronto, Toronto, ON, Canada Abstract: Though the guidelines for the optimal management of chronic obstructive pulmonary disease (COPD) following an acute exacerbation (AE) are well established, issues associated with poor adherence to nonpharmacological interventions such as self-management advice and pulmonary rehabilitation will impact on hospital readmission rates and health care costs. Systems developed for clinically stable patients with COPD may not be sufficient for those who are post-exacerbation. A redesign of the manner in which such interventions are delivered to patients following an AECOPD is necessary. Addressing two or more components of the chronic care model is effective in reducing health care utilization in patients with COPD, with self-management support contributing a key role. By refining self-management support to incorporate the identification and treatment of psychological symptoms and by providing health care professionals adequate time and training to deliver respiratory-specific advice and self-management strategies, adherence to nonpharmacological therapies following an AE may be enhanced. Furthermore, following up patients in their own homes allows for the tailoring of advice and for the delivery of consistent health care messages which may enable knowledge to be retained. By refining the delivery of nonpharmacological therapies following an AECOPD according to components of the chronic care model, adherence may be improved, resulting in better disease management and possibly reducing health care utilization.Keywords: acute exacerbation, chronic obstructive pulmonary disease, pulmonary rehabilitation, self-management, physical activity, oxygen, adherence, chronic care mode

Assessing caregiving experience in COPD: content validity of the Zarit Burden Interview

Caring for a relative with COPD influences multiple dimensions of carers' lives. Several instruments have been used to assess the caregiving experience in COPD,1 e.g. the Zarit Burden Interview (ZBI). This instrument was originally developed for use in carers of people with dementia, however, its applicability in COPD has not been tested. This study explored the content validity of the ZBI in carers of patients with COPD. Ten carers (68.2±6.9yrs, all female) of patients with COPD (74.7±5.3yrs, all male, FEV1=49.2±19.0%pred) participated in cognitive debriefing interviews. They were asked to complete the ZBI and verbalise their thinking process to assess the adequacy of its content and instructions. Interviews were recorded and transcribed for further analysis using the qualitative data analysis software (WebQDA). Responses to the ZBI were also analysed to explore floor/ceiling effects. From the 22 items of the ZBI, 6 items were relevant for all carers and 11 items were not relevant for at least one participant. Five of these 11 items were not relevant for ≥40% of the sample and were related to stress for providing care, embarrassment about patient’s behaviour and impacts on social/leisure time. The remaining 5 items were not consensual. Overall, the ZBI was well-understood although 8 items were less clear for some carers. They suggested: improving questions (n=1) and scoring (n=5); eliminating item 4 (n=2); including 2 questions about the caregiving context (n=1). Responses were mostly distributed in the option ‘Never/Not at all’. The ZBI in its current form should not be used to assess carer experience among those caring for patients with COPD.publishe

Changing and unchanging values in the world of the future, November 8, 9, and 10, 2001

This repository item contains a single issue of the Pardee Conference Series, a publication series that began publishing in 2006 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. This was the Center's Inaugural Conference that took place during November 8, 9, and 10, 2001. Organized by David Fromkin, Director Frederick S. Pardee Center for the Study of the Longer-Range Future. Co-Sponsored by Boston University and Carnegie Council on Ethics and International Affairs.This conference brought together a discussion of different perspectives on what future paradigm shifts will look like – in government, in foreign policy, in what constitutes “classics,” in economic and religious modes, and changes in the interaction between these values. The conference agreed that today’s Western society values democracy, constitutionalism, liberalism, rule of law, open society, and market economy. These are not contingent upon one another and may change. But the “needs and aspirations” of humanity will at their most essential core remain the same. The amount and type of power given to governments is not a fixed thing, and developments in the meaning of democracy and how it is achieved may illustrate this

Effects of exercise training on cognition in chronic obstructive pulmonary disease:A systematic review

Background As exercise may mitigate cognitive decline in individuals with chronic obstructive pulmonary disease (COPD), its effect has been evaluated in a number of clinical trials. The objective of the present systematic review was to describe the impact of exercise training on cognition in COPD. Methods Electronic searches of four databases were performed from inception until March 24, 2015 and last updated 23rd October 2017. Included studies reported on at least one cognitive outcome before and after a formal exercise-training program in individuals with COPD. Two reviewers independently rated study quality using the Downs and Black checklist. The protocol was registered on PROSPERO (CRD42015017884). Results Seven articles, representing six exercise interventions in 293 individuals with COPD (55% males, mean age 67 ± 2 year) were included. Although each study documented a significant pre-post training improvement in at least one cognitive domain, the heterogeneity in study design, exercise intervention and cognitive outcome measures among studies precluded a meta-analysis. The only randomized controlled trial available reported an improvement on a letter verbal fluency task in the exercise group only. Conclusions Exercise training may positively impact cognition in COPD patients, but current evidence is limited by the heterogeneity of study design, exercise intervention and cognitive outcome measures. Future studies should emphasize comprehensive reporting of intervention parameters, including program length, type(s) of exercise, and duration of individual sessions, in order to facilitate applied insights to inform replication and/or program development

Adjusting bone mass for differences in projected bone area and other confounding variables: an allometric perspective.

The traditional method of assessing bone mineral density (BMD; given by bone mineral content [BMC] divided by projected bone area [Ap], BMD = BMC/Ap) has come under strong criticism by various authors. Their criticism being that the projected bone "area" (Ap) will systematically underestimate the skeletal bone "volume" of taller subjects. To reduce the confounding effects of bone size, an alternative ratio has been proposed called bone mineral apparent density [BMAD = BMC/(Ap)3/2]. However, bone size is not the only confounding variable associated with BMC. Others include age, sex, body size, and maturation. To assess the dimensional relationship between BMC and projected bone area, independent of other confounding variables, we proposed and fitted a proportional allometric model to the BMC data of the L2-L4 vertebrae from a previously published study. The projected bone area exponents were greater than unity for both boys (1.43) and girls (1.02), but only the boy's fitted exponent was not different from that predicted by geometric similarity (1.5). Based on these exponents, it is not clear whether bone mass acquisition increases in proportion to the projected bone area (Ap) or an estimate of projected bone volume (Ap)3/2. However, by adopting the proposed methods, the analysis will automatically adjust BMC for differences in projected bone size and other confounding variables for the particular population being studied. Hence, the necessity to speculate as to the theoretical value of the exponent of Ap, although interesting, becomes redundant
