Clinicians' Views of Educational Interventions for Carers of Patients With Breathlessness Due to Advanced Disease: Findings From an Online Survey.

CONTEXT: Carers' needs in advanced disease, and specifically in relation to breathlessness, are well evidenced. Publications on educational interventions for carers of patients with advanced disease that focus on symptoms are scarce and absent for breathlessness. OBJECTIVES: To establish current education provided by clinicians for carers of patients with breathlessness in advanced disease, views about educating carers about breathlessness, and relevant outcomes for a future randomized controlled trial of an educational intervention for carers. METHODS: An online survey was completed by 365 clinicians: medical, nursing, and allied health professionals from primary care, hospital, and hospice. Descriptive statistics summarized respondent characteristics and survey responses, and the Chi-squared test was applied. Content analysis of free-text comments was conducted. RESULTS: Most clinicians reported educating carers by educating patients at clinical contacts with patients. Carer involvement was largely an 'add-on'; an active carer education strategy, where all carers were invited to attend, was not currently apparent. Clinicians endorsed the importance of educating carers about breathlessness through increasing carer confidence and/or control, helping patients' better self-manage breathlessness and potentially reducing admissions. Joint education with patients, giving practical advice, and strategies for helping patients were advised. To inform a future trial, clinicians identified improvement in patient outcomes, particularly patient quality of life as very important in enhancing clinician adoption of an educational intervention for carers. CONCLUSION: This survey revealed an appetite among clinicians for an educational intervention for carers of patients with breathlessness in advanced disease and provided important insights to underpin a future Phase II randomized controlled trial.This study was supported by a research grant from Dimbleby Cancer Care.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Evidence of perceived psychosocial stress as a risk factor for stroke in adults: a meta-analysis

BackgroundSeveral studies suggest that perceived psychosocial stress is associated with increased risk of stroke; however results are inconsistent with regard to definitions and measurement of perceived stress, features of individual study design, study conduct and conclusions drawn and no meta-analysis has yet been published. We performed a systematic review and meta-analysis of studies assessing association between perceived psychosocial stress and risk of stroke in adults.The results of the meta-analysis are presented.MethodsSystematic searches of MEDLINE, EMBASE, CINAHL, PsycInfo, and Cochrane Database of Systematic Reviews were undertaken between 1980 and June 2014. Data extraction and quality appraisal was performed by two independent reviewers. Hazard ratios (HR) and odds ratios (OR) were pooled where appropriate.Results14 studies were included in the meta-analysis, 10 prospective cohort, 4 case–control design. Overall pooled adjusted effect estimate for risk of total stroke in subjects exposed to general or work stress or to stressful life events was 1.33 (95 % confidence interval [CI], 1.17, 1.50; P  0.0001).A sex difference was noted with higher stroke risk identified for women (HR 1.90 95 % CI, 1.4, 2.56: P

Developing an educational intervention on breathlessness in advanced disease for informal carers

Background & aim: The evidence-base for educational interventions to support informal carers and enhance their caregiving capacity is limited. Our aim was to develop an evidence-based educational intervention on breathlessness in advanced disease for carers. Method: Stage 1: Qualitative in-depth interviews with purposive sample of 25 patient-carer dyads from two disease groups (COPD and cancer) to identify educational needs and intervention preferences. Stage 2: One-day multidisciplinary workshop with 13 clinical experts to identify evidence-based content and acceptability and feasibility of potential delivery modes. Stage 3: Two half-day workshops (one COPD and one cancer) with 10 carers and seven patients to review intervention content, format, and language. Qualitative data analysis used a Framework approach. Results: Carers wanted to learn about breathlessness. Six key topics emerged from patient-carer dyad interviews: understanding breathlessness, de-escalating anxiety and panic, keeping active, living positively, managing infections (in COPD), and knowing what to expect in the future. There was wide variation in how carers wanted to learn, but written resources were less popular than face-to-face, group, video and web-based learning. Carers wanted an intervention that drew on both clinical expertise and peer-carer experience. In general, they wanted to learn with the patient. Building on these findings, the clinical expert workshop identified evidence-based content for the six topics and discussed a potential web-based platform to facilitate multiple modes of access e.g. via clinicians, established support groups, or by carers independently. Carer workshops endorsed the need for the intervention, its content and format, and refined its language and presentation style. Conclusion: Developed with carer, patient and clinician expertise this educational intervention on breathlessness has the potential to be highly relevant and acceptable to carers

Humic substances interfere with detection of pathogenic prion protein

Studies examining the persistence of prions (the etiological agent of transmissible spongiform encephalopathies) in soil require accurate quantification of pathogenic prion protein (PrPTSE) extracted from or in the presence of soil particles. Here, we demonstrate that natural organic matter (NOM) in soil impacts PrPTSE detection by immunoblotting. Methods commonly used to extract PrPTSE from soils release substantial amounts of NOM, and NOM inhibited PrPTSE immunoblot signal. The degree of immunoblot interference increased with increasing NOM concentration and decreasing NOM polarity. Humic substances affected immunoblot detection of prion protein from both deer and hamsters. We also establish that after interaction with humic acid, PrPTSE remains infectious to hamsters inoculated intracerebrally, and humic acid appeared to slow disease progression. These results provide evidence for interactions between PrPTSE and humic substances that influence both accurate measurement of PrPTSE in soil and disease transmission

A CLN6-CLN8 complex recruits lysosomal enzymes at the ER for Golgi transfer

Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER) and transferred to the Golgi complex by interaction with the Batten disease protein CLN8 (ceroid lipofuscinosis, neuronal, 8). Here we investigated the relationship of this pathway with CLN6, an ER-associated protein of unknown function that is defective in a different Batten disease subtype. Experiments focused on protein interaction and trafficking identified CLN6 as an obligate component of a CLN6-CLN8 complex (herein referred to as EGRESS: ER-to-Golgi relaying of enzymes of the lysosomal system), which recruits lysosomal enzymes at the ER to promote their Golgi transfer. Mutagenesis experiments showed that the second luminal loop of CLN6 is required for the interaction of CLN6 with the enzymes but dispensable for interaction with CLN8. In vitro and in vivo studies showed that CLN6 deficiency results in inefficient ER export of lysosomal enzymes and diminished levels of the enzymes at the lysosome. Mice lacking both CLN6 and CLN8 did not display aggravated pathology compared with the single deficiencies, indicating that the EGRESS complex works as a functional unit. These results identify CLN6 and the EGRESS complex as key players in lysosome biogenesis and shed light on the molecular etiology of Batten disease caused by defects in CLN6
