Irisin is a recently discovered myokine that increases adipocyte metabolism, induces further "browning" of white adipose tissue, and enhances glucose metabolism. No study has ever determined how an acute bout of exercise impacts immediate post-exercise irisin concentration using a meta-analytic approach. The purpose of this study is to determine the impact of an acute bout of exercise on the magnitude of post-exercise irisin concentration in adults using meta-analytic procedures. Searches were performed on PubMed, EMBASE, CINAHL, PEDro, SCOPUS, and SPORTDiscus databases. Effect summaries were obtained using random-effects models. Random-effects single and multiple meta-regressions were performed to determine relationships between, and potential confounding effects of, variables of interest. Ten articles were retained for the final meta-analysis, producing 21 study estimates. An acute bout of exercise was accompanied by a post-exercise average increase in irisin concentration of 15.0 (95% CI: 10.8%-19.3%). There was no significant relationship between post-exercise irisin concentration and age, intensity of aerobic exercise, or type of exercise training session (resistance vs aerobic training). Fitness level and body mass index were identified as significant predictive variables for post-exercise irisin concentration. However, a multiple meta-regression model identified fitness level as the single best predictor, with being fit (21.1%±2.2%) associated with a nearly twofold increase in post-exercise irisin concentration, compared with being unfit (11.8%±2.1%). Immediately following an acute bout of exercise, irisin concentration increases substantially in adults, with fitness level as an important modifier for the effect.

Health-related quality of life (HRQOL) is an emerging method to quantify the consequences of pediatric mild traumatic brain injury (mTBI)/concussion in both clinical practice and research. However, to utilize HRQOL measurements to their full potential in the context of mTBI/concussion recovery, a better understanding of the typical course of HRQOL after these injuries is needed. The objective of this study was to summarize current knowledge on HRQOL after pediatric mTBI/concussion and identify areas in need of further research. The following databases from their earliest date of coverage through June 1, 2015 were used: MEDLINE(®), PubMed, Embase, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), SPORTDiscus, Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), and Child Development and Adolescent Studies (CDAS). Studies must have examined and reported HRQOL in a pediatric population after mTBI/concussion, using a validated HRQOL measurement tool. Eight of 1660 records identified ultimately met inclusion criteria. Comprehensive data were extracted and checked by a second reviewer for accuracy and completeness. There appears to be a small but important subgroup of patients who experience poor HRQOL outcomes up to a year or longer post-injury. Potential predictors of poor HRQOL include older age, lower socioeconomic status, or a history of headaches or trouble sleeping. Differing definitions of mTBI precluded meta-analysis. HRQOL represents an important outcome measure in mTBI/concussion clinical practice and research. The evidence shows that a small but important proportion of patients have diminished HRQOL up to a year or longer post-injury. Further study on this topic is warranted to determine the typical longitudinal progression of HRQOL after pediatric concussion.

Objectives:To review and synthesize the currently available research on whether early intervention for psychosis programs reduce the use of inpatient services.Methods:A systematic review was conducted using keywords searches on PubMed, Embase (Ovid), PsycINFO (ProQuest), Scopus, CINAHL (EBSCO), Social Work Abstracts (EBSCO), Social Science Citations Index (Web of Science), Sociological Abstracts (ProQuest), and Child Development & Adolescent Studies (EBSCO). To be included, studies had to be peer-reviewed publications in English, examining early intervention programs using a variant of assertive community treatment, with a control/comparison group, and reporting inpatient service use outcomes. The primary outcome extracted number hospitalized and total N. Secondary outcome extracted means and standard deviations. Data were pooled using random effects models. Primary outcome was the occurrence of any hospitalization during treatment. A secondary outcome was the average bed-days used during treatment period.Results:Fifteen projects were identified and included in the study. Results of meta-analysis supported the occurrence of a positive effect for intervention for both outcome measures (any hospitalization OR: 0.33; 95% CI 0.18–0.63, bed-days usage SMD: −0.38, 95% CI −0.53 to −0.24). There was significant heterogeneity of effect across the studies. This heterogeneity is due to a handful of studies with unusually positive responses.Conclusion:These results suggest that early intervention programs are superior to standard of care, with respect to reducing inpatient service usage. Wider use of these programs may prevent the occurrence of admission for patients experiencing the onset of psychotic symptoms.

BackgroundWe performed a systematic review and meta-analysis to evaluate the efficacy and safety of high-flow oxygen via nasal cannulae (HFNC) compared to non-invasive ventilation (NIV) and/or standard oxygen in patients with acute, hypoxemic respiratory failure.MethodsWe reviewed randomized controlled trials from CENTRAL, EMBASE, MEDLINE, Scopus and the International Clinical Trials Registry Platform (inception to February 2016), conference proceedings, and relevant article reference lists. Two reviewers independently screened and extracted trial-level data from trials investigating HFNC in patients with acute, hypoxemic respiratory failure. Internal validity was assessed in duplicate using the Cochrane Risk of Bias tool. The strength of evidence was assessed in duplicate using the Grading of Recommendations Assessment, Development and Evaluation framework. Our primary outcome was mortality. Secondary outcomes included dyspnea, PaO2:FiO2 ratio, PaCO2, and pH. Safety outcomes included respiratory arrest, intubation, delirium, and skin breakdown.ResultsFrom 2023 screened citations, we identified seven trials (1771 patients) meeting inclusion criteria. All trials were at high risk of bias due to lack of blinding. There was no evidence for a mortality difference in patients receiving HFNC vs. NIV and/or standard oxygen (RR 1.01, 95% CI 0.69 to 1.48, I 2 = 63%, five trials, 1629 patients). In subgroup analyses of HFNC compared to NIV or standard oxygen individually, mortality differences were not observed. Measures of patient tolerability were heterogeneous. The PaO2:FiO2 ratio at 6–12 h was significantly lower in patients receiving oxygen via HFNC compared to NIV or standard oxygen for hypoxemic respiratory failure (MD − 53.34, 95% CI − 71.95 to − 34.72, I 2 = 61%, 1143 patients). There were no differences in pH, PaCO2, or rates of intubation or cardio-respiratory arrest. Delirium and skin breakdown were infrequently reported in included trials.ConclusionsIn patients with acute hypoxemic respiratory failure HFNC was not associated with a difference in mortality compared to NIV or standard oxygen. Secondary outcomes including dyspnea, tolerance, and safety were not systematically reported. Residual heterogeneity and variable reporting of secondary outcomes limit the conclusions that can be made in this review. Prospective trials designed to evaluate the efficacy and safety of HFNC in patients with acute hypoxemic respiratory failure are required.Electronic supplementary materialThe online version of this article (10.1186/s13643-017-0593-5) contains supplementary material, which is available to authorized users.

Background Telemonitoring and telerehabilitation can support home-based pulmonary rehabilitation (PR) and benefit patients with lung diseases or COVID-19. This study aimed to (1) identify which telemonitoring and telerehabilitation interventions (e.g. videoconferencing) are used to provide telehealth care for people with chronic respiratory conditions or COVID-19, and (2) provide an overview of the effects of telemonitoring and telerehabilitation on exercise capacity, physical activity, health-related QoL (HRQoL), and healthcare use in patients with lung diseases or COVID-19. Methods A search was performed in the electronic databases of Ovid MEDLINE, EMBASE, and Cinahl through 15 June 2021. Subject heading and keywords were used to reflect the concepts of telemonitoring, telerehabilitation, chronic lung diseases, and COVID-19. Studies that explored the effect of a telerehabilitation and/or telemonitoring intervention, in patients with a chronic lung disease such as asthma, chronic obstructive pulmonary diseases (COPD), or COVID-19, and reported the effect of the intervention in one or more of our outcomes of interest were included. Excluding criteria included evaluation of new technological components, teleconsultation or one-time patient assessment. Results This scoping review included 44 publications reporting the effect of telemonitoring (25 studies), telerehabilitation (8 studies) or both (11 studies) on patients with COPD (35 studies), asthma (5 studies), COPD and asthma (1 study), and COVID-19 (2 studies). Patients who received telemonitoring and/or telerehabilitation had improvements in exercise capacity in 9 out of 11 (82%) articles, better HRQoL in 21 out of 25 (84%), and fewer health care use in 3 out of 3 (100%) articles compared to pre-intervention. Compared to controls, no statistically significant differences were found in the intervention groups’ exercise capacity in 5 out 6 (83%) articles, physical activity in 3 out of 3 (100%) articles, HRQoL in 21 out of 25 (84%) articles, and healthcare use in 15 out of 20 (75%) articles. The main limitation of the study was the high variability between the characteristics of the studies, such as the number and age of the patients, the outcome measures, the duration of the intervention, the technological components involved, and the additional elements included in the interventions that may influence the generalization of the results. Conclusion Telemonitoring and telerehabilitation interventions had a positive effect on patient outcomes and appeared to be as effective as standard care. Therefore, they are promising alternatives to support remote home-based rehabilitation in patients with chronic lung diseases or COVID-19.
