Abstract: Background The magnitude of response to pulmonary rehabilitation (PR) is influenced by the selection of outcomes and measures. Objectives This systematic review aimed to review all outcomes and measures used in clinical trials of PR for individuals with chronic obstructive pulmonary disease (COPD). Methods The review involved a search of Scopus, Web of Knowledge, Cochrane Library, EBSCO, Science Direct and PubMed databases for studies of stable individuals with COPD undergoing PR. Frequency of reporting for each domain, outcome and measure was synthesized by using Microsoft Excel. Results We included 267 studies (43153 individuals with COPD). A broad range of domains (n = 22), outcomes (n = 163) and measures (n = 217) were reported. Several measures were used for the same outcome. The most reported outcomes were exercise capacity (n = 218) assessed with the 6-min walk test (n = 140), health-related quality of life (n = 204) assessed with the Saint George's respiratory questionnaire (n = 99), and symptoms (n = 158) assessed with the modified Medical Research Council dyspnoea scale (n = 56). The least reported outcomes were comorbidities, adverse events and knowledge. Conclusions This systematic review reinforces the need for a core outcome set for PR in individuals with COPD because of high heterogeneity in reported outcomes and measures. Future studies should assess the importance of each outcome for PR involving different stakeholders. PROSPERO ID CRD42017079935

Abstract: A metastable β Ti alloy was additively manufactured by laser powder bed fusion (LPBF). Tensile testing along the build direction of the as-LPBF material (LPBF-0°) revealed significant work softening immediately following yielding with no uniform deformation. By contrast, substantial work hardening and uniform elongation well over 10% were achieved perpendicular to the build direction (LPBF-90°). Similar effects were obtained in the build direction after super transus heat treatment (LPBF-0°+HT) although the strength was slightly lowered. In addition, the yield drop phenomenon observed in both orientations of the as-LPBF materials disappeared after HT. The enhanced work hardening ability, and thus ductility, can be attributed to increased interactions of slip bands/slip bands owing to additional {112} slip systems becoming operative in LPBF-0°+HT and LPBF-90° while LPBF-0° was dominated by {110} only. The other variations after HT may be related to the coarsening of grain structure and removal of specific substructures in the as-LPBF microstructure.

Abstract: Background : The spouse is recognised as the ideal person for providing comprehensive and sustainable support for menopausal women. However, existing validated questionnaires to measure such support are limited. This study developed a new instrument, the Menopausal Spousal Support Questionnaire (MSSQ), for measuring spouses’ support for menopausal women, and validated its psychometric properties. Methods : The MSSQ was developed and then validated using sequential exploratory mixed methods in two phases. In Phase I, the MSSQ was developed based on a literature review, in-depth interviews with 13 menopausal women and discussions within the research team. This was followed by Phase II, in which a two-step validation process was conducted to perform (a) an exploratory factor analysis (EFA) with data from 146 menopausal women and (b) a confirmatory factor analysis (CFA) with data from 431 menopausal women. The results were used to determine the psychometric properties of the newly developed MSSQ. Results : The final MSSQ consisted of 17 items in four domains: appraisal support, intimacy support, emotional support and instrumental support. The modelling results demonstrated a good model fit: root mean square of error approximation (RMSEA) = 0.075, comparative fit index (CFI) = 0.942, Tucker-Lewis Index (TLI) = 0.921, chi-square/degree of freedom (ChiSq/df) = 3.546). The scale also proved to be reliable: composite reliability (CR) > 0.6, average variance extracted (AVE) > 0.5, internal reliability (IR) > 0.93. Conclusions : The MSSQ is psychometrically valid for measuring spousal support for menopausal women and could also serve as a screening tool for healthcare providers.

Abstract: Purpose To compare neurally adjusted ventilatory assist (NAVA), proportional assist ventilation (PAV), adaptive support ventilation (ASV) and Smartcare pressure support (Smartcare/PS) with standard pressure support ventilation (PSV) regarding their effectiveness for weaning critically ill adults from invasive mechanical ventilation (IMV). Methods Electronic databases were searched to identify parallel-group randomized controlled trials (RCTs) comparing NAVA, PAV, ASV, or Smartcare/PS with PSV, in adult patients under IMV through July 28, 2021. Primary outcome was weaning success. Secondary outcomes included weaning time, total MV duration, reintubation or use of non-invasive MV (NIMV) within 48 h after extubation, in-hospital and intensive care unit (ICU) mortality, in-hospital and ICU length of stay (LOS) (PROSPERO registration No:CRD42021270299). Results Twenty RCTs were finally included. Compared to PSV, NAVA was associated with significantly lower risk for in-hospital and ICU death and lower requirements for post-extubation NIMV. Moreover, PAV showed significant advantage over PSV in terms of weaning rates, MV duration and ICU LOS. No significant differences were found between ASV or Smart care/PS and PSV. Conclusions Moderate certainty evidence suggest that PAV increases weaning success rates, shortens MV duration and ICU LOS compared to PSV. It is also noteworthy that NAVA seems to improve in-hospital and ICU survival.
