RESUMEN
Background: Chronic obstructive pulmonary disease (COPD) is characterized by important extrapulmonary alterations that could affect the performance in dual task (DT) (motor and cognitive tasks executed simultaneously), which is defined as DT interference (DTI). Objective: To compare the performance of DT between individuals with COPD and healthy control subjects (HCSs). Methods: The literature search was conducted in seven databases (Medline, Scopus, Web of Science, PEDro, SciELO, LILACS, and Google Scholar) up to December 2023, including studies published in English, Spanish, or Portuguese. Studies with individuals diagnosed with COPD older than 60 years, who were evaluated with any DT assessment, and compared with HCS were included. The quality of the studies was evaluated using the risk of bias in nonrandomized studies of interventions (ROBINS-I). The meta-analysis was performed with JAMOVI software 5.4. The study protocol was registered on PROSPERO (CRD42023435212). Results: From a total of 128 articles, 5 observational studies were selected in this review, involving 252 individuals aged between 60 and 80 years, from France, Italy, Canada, Turkey, and Belgium. Notable DTI was observed in individuals with COPD compared to HCS (standard mean difference [SMD] = 0.91; 95% confidence interval (CI) 0.06-1.75, p = 0.04). Individuals with COPD had impaired gait speed, balance control, muscle strength, and cognitive interference during DT compared to HCS. DT assessment protocols included different combination of motor and cognitive tasks, using functional test, gait analysis, and muscle strength paired with countdown and verbal fluency tasks. Studies presented low (n = 2), moderate (n = 1), and serious (n = 2) overall risk of bias. Conclusion: Older adults diagnosed with COPD exhibited a significant DTI compared to HCSs, which is characterized by poorer physical and cognitive performance during DT execution. These findings highlight the importance of incorporating DT assessments into clinical practice for individuals with COPD.

Abstract Introduction Resilience is a commonly discussed term describing the ability to overcome, adapt to, or cope with stressful/disruptive events. Although researchers and practitioners define resilience in diverse ways - e.g., psychological or disaster resilience - the concept fundamentally encompasses perseverance through adversity. As experts in the interplay between individuals, environments, and occupations, occupational therapists and occupational scientists have great potential to understand and enable resilience, with some similar concepts appearing in occupational theories (e.g., occupational adaptation). However, there are no published reviews of resilience in the occupation-focused literature. Objective We will explore how resilience is conceptualized and operationalized in the occupational therapy and occupational science research literature. Method Guided by the Joanna Briggs Institute scoping review methodology, we will search library databases and other sources for relevant records. Two team members will screen records for inclusion, with discrepancies settled by a third person. We will include English-language literature (including research papers, editorials, dissertations, etc.) published since 1990 which 1) contains the word root 'resilien*' and 2) is occupation focused, according to our criteria (occupational therapist/occupational scientist co-authors or research participants; and/or published in occupation-focused periodical). We will report key information of included literature, such as methodology and resilience theories discussed. Results Our study is ongoing at the time of publication; this manuscript reports its protocol without results. Conclusion Findings will be useful for clinicians and researchers looking for occupational conceptualizations of resilience. From a social justice perspective, our review may highlight evidence that occupational engagement can foster resilience among marginalized communities.
Resumo Introdução Resiliência é um termo que descreve a habilidade de superar, adaptar ou lidar com eventos estressantes ou perturbadores. Embora pesquisadores e profissionais definam resiliência de diversas maneiras - como resiliência psicológica ou a desastres - o conceito fundamentalmente engloba perseverança no enfrentamento de adversidades. Como especialistas na interação entre indivíduos, comunidades, ambientes e ocupações, terapeutas ocupacionais e cientistas ocupacionais têm potencial para compreender e propiciar a resiliência, com alguns conceitos semelhantes (como adaptação ocupacional). Entretanto, não há nenhuma revisão publicada sobre resiliência na área. Objetivo Explorar como a resiliência é conceituada e operacionalizada na literatura científica de terapia ocupacional e ciência ocupacional. Método Guiados pela metodologia para revisões de escopo proposta pelo Instituto Joanna Briggs, buscou-se por documentos em bases de dados científicas e outras fontes. Dois membros da equipe revisaram documentos para inclusão e as discrepâncias foram resolvidas por uma terceira pessoa. Utilizou-se literatura em inglês (artigos de pesquisa, editoriais, dissertações etc.) publicada desde 1990 que: (1) contenha 'resilien*' e (2) seja focada na ocupação, desde que: terapeutas ocupacionais ou cientistas ocupacionais fossem coautores ou participantes da pesquisa; e/ou publicada em periódico focado em terapia ocupacional/ciência ocupacional. Foram reportadas as principais informações dos documentos incluídos, como a metodologia e as teorias de resiliência. Resultados Este estudo está em andamento; foca-se aqui no protocolo de pesquisa, sem resultados. Conclusão As discussões serão úteis para profissionais na prática clínica e pesquisadores buscando por uma conceituação ocupacional de resiliência. De uma perspectiva de justiça social, essa revisão pode destacar evidências de que o engajamento com ocupações pode promover resiliência entre comunidades marginalizadas.
RESUMEN
We hypothesised that biomass smoke exposure is associated with an airway-predominant chronic obstructive pulmonary disease (COPD) phenotype, while tobacco-related COPD is associated with an emphysema-predominant phenotype. In this cross-sectional study, female never-smokers with COPD and biomass exposure (n=21) and female ex-cigarette smokers with COPD without biomass exposure (n=22) completed computed tomography (CT) at inspiration and expiration, pulmonary function, blood gas, exercise tolerance, and quality of life measures. Two radiologists scored the extent of emphysema and air trapping on CT. Quantitative emphysema severity and distribution and airway wall thickness were calculated using specialised software. Women in the tobacco group had significantly more emphysema than the biomass group (radiologist score 2.3 versus 0.7, p=0.001; emphysema on CT 27% versus 19%, p=0.046; and a larger size of emphysematous spaces, p=0.006). Women in the biomass group had significantly more air trapping than the tobacco group (radiologist score 2.6 and 1.5, respectively; p=0.02) and also scored lower on the symptom, activities and confidence domains of the quality of life assessment and had lower oxygen saturation at rest and during exercise (p<0.05). Biomass smoke exposure is associated with less emphysema but more air trapping than tobacco smoke exposure, suggesting an airway-predominant phenotype.
