Prevalence of indoor air pollutants from First Nation homes in North Central British Columbia, Canada.

Poor indoor air quality poses significant health risks. This study addresses the gap in knowledge regarding the prevalence of indoor air pollutants in remote and rural First Nation communities in north-central British Columbia, Canada. Dust samples from 75 homes were collected and analysed for house dust mites, pet allergens, mould antigens, and bacterial endotoxins. Indoor air quality parameters, including carbon monoxide, carbon dioxide, particulate matter, temperature, and humidity, were measured. A detailed questionnaire on household characteristics and potential pollutant sources was administered. Homes exhibited exposure to multiple pollutants, with wood stove smoke identified as a primary source. Felis domesticus (cat allergen) and Canis familiaris (dog allergen) were prevalent, with detectable levels in 64% and 60% of homes, respectively. Bacterial endotoxins were present in all households. One-third of homes exceeded recommended thresholds for 3 or more pollutants. This study provides critical insights into the prevalence and magnitude of indoor air pollutants, contributing to a broader initiative to characterise respiratory health in First Nations communities. While many homes in First Nations communities had acceptable air quality, one-third of homes exceeded thresholds for 3 or more pollutants. The results can guide ongoing community efforts to address housing concerns and advocate for increased federal funding.

Social support from the physiotherapist and the therapeutic relationship in physiotherapy: bridging theory to practice.

BACKGROUND/PURPOSE: Therapeutic relationship and social support are critical components in physiotherapy that shape patient outcomes. However, defining these constructs, discerning their similarities and differences, and measuring them pose challenges. This article aims to facilitate scientific and clinical advancement on social support and the therapeutic relationship in physiotherapy by (a) providing conceptual clarity, (b) discussing measurement tools, and (c) offering practical recommendations for the deliberate incorporation of these constructs in clinical practice. METHODS: This is a perspective paper drawing on examples from existing research. KEY RESULTS: Assessing the nature and strength of social support and promoting naturally occurring social support networks are practical ways for physiotherapists to foster social support in physiotherapy clinical practice. Physiotherapists can offer direct support, facilitate the development of an individual's social skills, and promote participation in group activities. To strengthen the therapeutic relationship, it is important to maintain good communication, foster connectedness with the patient, demonstrate professional skills, and adopt a reflective practice. Physiotherapists are encouraged to establish clear roles and responsibilities, prioritize individualized patient-centered care, and involve patients in shared decision-making, ensuring congruence in goals and expectations. Willingness to dedicate time and energy within and beyond direct patient-therapist interactions can foster connections. Moreover, using the body - which is the main point of contact with patients - and physical touch can help physiotherapists to connect with patients. Finally, physiotherapists must be prepared to address and mend any conflicts which can impact the relationship's trajectory. CONCLUSION: Social support and therapeutic relationships are complementary aspects of one's health care, and it is crucial to purposefully account for both in physiotherapy practice to optimize person-centered care and rehabilitation outcomes.

A systematic review of exercise studies for individuals hospitalized with an acute exacerbation of chronic obstructive pulmonary disease: Focus on the principles of exercise training.

BACKGROUND: For exercise interventions to be effectively reproduced or applied in a "real world" clinical setting, clinical trials must thoroughly document all components of the exercise prescription and ensure that participants adhere to each component. However, previous reviews have not critically examined the quality of exercise prescription of inpatient Pulmonary Rehabilitation (PR) programs. OBJECTIVE: The objectives of this review were to evaluate the (a) application of the principles of exercise training, (b) reporting of the frequency, intensity, time and type (FITT) components of exercise prescription, and (c) reporting of patient's adherence to the FITT components in intervention studies for patients admitted to hospital for an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: Relevant scientific databases were searched for randomized controlled trials (RCTs) that compared in-hospital PR with usual care for people hospitalized with AECOPD. Title and abstract followed by full-text screening were conducted independently by two reviewers. Data were extracted and synthesized to evaluate the application of the principles of exercise training and the reporting/adherence of the FITT components. RESULTS: Twenty-seven RCTs were included. Only two applied all principles of exercise training. Specificity was applied by 70%, progression by 48%, overload by 37%, initial values by 89% and diminishing returns and reversibility by 37% of trials. Ten trials adequately reported all FITT components. Frequency and type were the components most reported (85% and 81%, respectively), while intensity was less frequently reported (52%). Only three trials reported on the patient's adherence to all four components. CONCLUSIONS: Studies have not adequately reported the exercise prescription in accordance with the principles of exercise training nor reported all the FITT components of the exercise prescription and patient's adherence to them. Therefore, interpretation of the current literature is limited and information for developing exercise prescriptions to individuals hospitalized with an AECOPD is lacking.

Scoping review of telehealth use by Indigenous populations from Australia, Canada, New Zealand, and the United States.

INTRODUCTION: Telehealth has the potential to address health disparities experienced by Indigenous people, especially in remote areas. This scoping review aims to map and characterize the existing evidence on telehealth use by Indigenous people and explore the key concepts for effective use, cultural safety, and building therapeutic relationships. METHODS: A search for published and gray literature, written in English, and published between 2000 and 2022 was completed in 17 electronic databases. Two reviewers independently screened retrieved records for eligibility. For included articles, data were extracted, categorized, and analyzed. Synthesis of findings was performed narratively. RESULTS: A total of 321 studies were included. The most popular type of telehealth used was mHealth (44%), and the most common health focuses of the telehealth interventions were mental health (26%) and diabetes/diabetic retinopathy (13%). Frequently described barriers to effective telehealth use included concerns about privacy/confidentiality and limited internet availability; meanwhile, telehealth-usage facilitators included cultural relevance and community engagement. Although working in collaboration with Indigenous communities was the most frequently reported way to achieve cultural safety, 40% of the studies did not report Indigenous involvement. Finally, difficulty to establish trusting therapeutic relationships was a major concern raised about telehealth, and evidence suggests that having the first visit-in-person is a potential way to address this issue. CONCLUSION: This comprehensive review identified critical factors to guide the development of culturally-informed telehealth services to meet the needs of Indigenous people and to achieve equitable access and positive health outcomes.

Influence of mild pulmonary congestion on diaphragmatic mobility and activities of daily living in chronic kidney disease: An experimental and clinical study.

BACKGROUND: Pulmonary congestion is a strong predictor of mortality and cardiovascular events in chronic kidney disease (CKD); however, the effects of the mild form on functionality have not yet been investigated. The objective of this study was to assess the influence of mild pulmonary congestion on diaphragmatic mobility (DM) and activities of daily living (ADL) in hemodialysis (HD) subjects, as well as compare ADL behavior on dialysis and non-dialysis days. In parallel, experimentally induce CKD in mice and analyze the resulting pulmonary and functional repercussions. METHODS: Thirty subjects in HD underwent thoracic and abdominal ultrasonography, anthropometric assessment, lung and kidney function, respiratory muscle strength assessment and symptoms analysis. To measure ADL a triaxial accelerometer was used over seven consecutive days. Twenty male mice were randomized in Control and CKD group. Thoracic ultrasonography, TNF-α analysis in kidney and lung tissue, exploratory behavior and functionality assessments were performed. RESULTS: Mild pulmonary congestion caused a 26.1% decline in DM (R2=.261; P=.004) and 20% reduction in walking time (R2=.200; P=.01), indicating decreases of 2.23mm and 1.54min, respectively, for every unit increase in lung comet-tails. Regarding ADL, subjects exhibited statistically significant differences for standing (P=.002), walking (P=.034) and active time (P=.002), and number of steps taken (P=.01) on days with and without HD. In the experimental model, CKD resulted in increased levels of TNF-α on kidneys (P=.037) and lungs (P=.02), attenuation of exploratory behavior (P=.01) and significant decrease in traveled distance (P=.034). Thoracic ultrasonography of CKD mice showed presence of B-lines. CONCLUSION: The mild pulmonary congestion reduced DM and walking time in subjects undergoing HD. Individuals were less active on dialysis days. Furthermore, the experimental model implies that the presence of pulmonary congestion and inflammation may play a decisive role in the low physical and exploratory performance of CKD mice.

Safety and Efficacy of Inpatient Pulmonary Rehabilitation for Patients Hospitalized with an Acute Exacerbation of Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-analyses.

Rationale: Pulmonary rehabilitation (PR) during hospitalization for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) occurs during a period of disease instability for the patient, and the safety and efficacy of PR, specifically during the hospitalization period, have not been established. Objective: The purpose of this review is to determine the safety and efficacy of PR during the hospitalization phase for individuals with AECOPD. Methods: Scientific databases were searched up to August 2022 for randomized controlled trials that compared in-hospital PR with usual care. PR programs commenced during the hospitalization and included a minimum of two sessions. Titles and abstracts followed by full-text screening and data extraction were conducted independently by two reviewers. The intervention effect estimates were calculated through meta-analysis using a random-effect model. Results: A total of 27 studies were included (n = 1,317). The meta-analysis showed that inpatient PR improved the 6-minute-walk distance by 105 m (P < 0.001). Inpatient PR improved the performance on the five-repetition sit-to-stand test by -7.02 seconds (P = 0.03). Quality of life (QOL), as measured by the 5-level EuroQoL Group-5 dimension version (EQ-ED-5L) and the St. George's Respiratory Questionnaire, was significantly improved by the intervention. Inpatient PR increased lower limb muscle strength by 33.35 N (P < 0.001). There was no change in the length of stay. Only one serious adverse event related to the intervention was reported. Conclusions: This review suggests that it is safe and effective to provide PR during hospitalization for individuals with AECOPD. In-hospital PR improves functional exercise capacity, QOL, and lower limb strength without prolonging the hospital length of stay.
