Six-minute walking distance and desaturation-distance ratio in allogeneic stem cell transplantation.

BACKGROUND: Most patients with haematological malignancies who undergo allogeneic haematopoietic stem cell transplant (HSCT) receive chemotherapy before the transplant to control the disease. Certain chemotherapy drugs can cause lung toxicity. Conversely, in patients with chronic respiratory conditions, the 6-min walking test (6MWT) and the desaturation-distance ratio (DDR) have demonstrated prognostic significance. Our objective was to determine whether the 6MWD and DDR, assessed prior to HSCT, have a prognostic impact on survival at 24 months post-HSCT. METHODS: A prospective experimental study was conducted in consecutive patients referred for allogeneic HSCT at Hospital Clinic, Barcelona, Spain. A complete functional respiratory study, including the 6MWT and DDR, was conducted prior to admission. The area under the curve (AUC) and cut-off points were calculated. Data on patients' characteristics, HSCT details, main events, with a focus on lung complications, and survival at 24 months were analysed. RESULTS: One hundred and seventy-five patients (39% women) with mean age of 48 ± 13 years old were included. Before HSCT, forced vital capacity and forced expiratory volume in the first second were 96% ± 13% predicted and 92% ± 14% predicted, respectively; corrected diffusing capacity for carbon monoxide 79% ± 15% predicted; 6MWD was 568 ± 83 m and DDR of .27 (.20-.41). The cut-off points for 6MWD and DDR were 566 m, [.58 95% CI (.51-.64)], p = .024 and .306, [.63 95% CI (.55-.70)], p = .0005, respectively. The survival rate at 24 months was 55%. CONCLUSION: Our results showed that individuals who exhibit a 6MWD shorter than 566 ms or a decline in DDR beyond .306 experienced reduced survival rates at 24 months after HSCT.

Inspiratory muscle training in patients with obesity: a systematic review and meta-analysis.

Introduction: Obesity is a chronic medical condition that affects, among others, the cardiovascular and respiratory systems. Interventions for its treatment focus on sustained weight reduction and general health improvement, leaving respiratory management aside. Our objective was to determine the effects of inspiratory muscle training (IMT) in patients with obesity. Methods: A systematic review was performed in Embase, Cochrane Library (CENTRAL), CINAHL, Web of Science, and PubMed/MEDLINE on June 26, 2023. Randomized clinical trials (RCTs), and quasi-randomized clinical trials investigating the effects of IMT in people with obesity were included. Selected studies were screened by two independent reviewers who extracted data and assessed the quality of the evidence. Results: The initial search returned 705 potential studies were included. Ultimately, eight studies met the criteria for eligibility and were included in the review. IMT improves physical capacity [6-minute walk test (6MWT): 44.5 m, 95% CI: 30.5 to 58.5; p < 0.0001] and the strength of the inspiratory muscles [maximal inspiratory pressure (MIP): -28.4 cm H2O, 95% CI: -41.9 to -14.8; p < 0.0001] compared to the controls, without differences in the pulmonary function, body mass index (BMI) and metabolic parameters. Conclusion: Inspiratory muscle training improves physical capacity and inspiratory muscle strength without significant changes in lung function, BMI, and metabolic parameters.Systematic review registration: PROSPERO, identifier CRD42023439625, https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023439625.

Acupoint Transcutaneous Electrical Nerve Stimulation in Hospitalized COPD Patients with Severe Dyspnoea: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect of acupuncture transcutaneous electrical nerve stimulation (acuTENS) on the reduction of dyspnoea during acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: A multicentric randomized control trial with masked patients and evaluators was carried out. During hospitalization, AECOPD patients received 45 min of acuTENS (experimental group) or sham acuTENS (controls) daily on 5 consecutive days. The trial was conducted at the Hospital del Mar, Barcelona, and Hospital Sant Joan de Déu, Manresa (both in Spain). Dyspnoea and peak expiratory flow were measured daily from the first to fifth days. Length of stay, readmissions at 3 months and adverse events were also analysed. RESULTS: Finally, 19 patients with moderately to severely exacerbated COPD were included. Although some tendencies in dyspnoea during day 1 and length of hospital stay were found favouring acupuncture, no significant differences were shown between groups. CONCLUSIONS: The acuTENS intervention was feasible#well tolerated in AECOPD patients and no important side effects were reported.

Chest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old.

BACKGROUND: Acute bronchiolitis is the leading cause of medical emergencies during winter months in infants younger than 24 months old. Chest physiotherapy is sometimes used to assist infants in the clearance of secretions in order to decrease ventilatory effort. This is an update of a Cochrane Review first published in 2005 and updated in 2006, 2012, and 2016. OBJECTIVES: To determine the efficacy of chest physiotherapy in infants younger than 24 months old with acute bronchiolitis. A secondary objective was to determine the efficacy of different techniques of chest physiotherapy (vibration and percussion, passive exhalation, or instrumental). SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, LILACS, Web of Science, PEDro (October 2011 to 20 April 2022), and two trials registers (5 April 2022). SELECTION CRITERIA: Randomised controlled trials (RCTs) in which chest physiotherapy was compared to control (conventional medical care with no physiotherapy intervention) or other respiratory physiotherapy techniques in infants younger than 24 months old with bronchiolitis. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: Our update of the searches dated 20 April 2022 identified five new RCTs with 430 participants. We included a total of 17 RCTs (1679 participants) comparing chest physiotherapy with no intervention or comparing different types of physiotherapy. Five trials (246 participants) assessed percussion and vibration techniques plus postural drainage (conventional chest physiotherapy), and 12 trials (1433 participants) assessed different passive flow-oriented expiratory techniques, of which three trials (628 participants) assessed forced expiratory techniques, and nine trials (805 participants) assessed slow expiratory techniques. In the slow expiratory subgroup, two trials (78 participants) compared the technique with instrumental physiotherapy techniques, and two recent trials (116 participants) combined slow expiratory techniques with rhinopharyngeal retrograde technique (RRT). One trial used RRT alone as the main component of the physiotherapy intervention. Clinical severity was mild in one trial, severe in four trials, moderate in six trials, and mild to moderate in five trials. One study did not report clinical severity. Two trials were performed on non-hospitalised participants. Overall risk of bias was high in six trials, unclear in five, and low in six trials. The analyses showed no effects of conventional techniques on change in bronchiolitis severity status, respiratory parameters, hours with oxygen supplementation, or length of hospital stay (5 trials, 246 participants).  Regarding instrumental techniques (2 trials, 80 participants), one trial observed similar results in bronchiolitis severity status when comparing slow expiration to instrumental techniques (mean difference 0.10, 95% confidence interval (C) -0.17 to 0.37).  Forced passive expiratory techniques failed to show an effect on bronchiolitis severity in time to recovery (2 trials, 509 participants; high-certainty evidence) and time to clinical stability (1 trial, 99 participants; high-certainty evidence) in infants with severe bronchiolitis. Important adverse effects were reported with the use of forced expiratory techniques.  Regarding slow expiratory techniques, a mild to moderate improvement was observed in bronchiolitis severity score (standardised mean difference -0.43, 95% CI -0.73 to -0.13; I2 = 55%; 7 trials, 434 participants; low-certainty evidence). Also, in one trial an improvement in time to recovery was observed with the use of slow expiratory techniques. No benefit was observed in length of hospital stay, except for one trial which showed a one-day reduction. No effects were shown or reported for other clinical outcomes such as duration on oxygen supplementation, use of bronchodilators, or parents' impression of physiotherapy benefit. AUTHORS' CONCLUSIONS: We found low-certainty evidence that passive slow expiratory technique may result in a mild to moderate improvement in bronchiolitis severity when compared to control. This evidence comes mostly from infants with moderately acute bronchiolitis treated in hospital. The evidence was limited with regard to infants with severe bronchiolitis and those with moderately severe bronchiolitis treated in ambulatory settings. We found high-certainty evidence that conventional techniques and forced expiratory techniques result in no difference in bronchiolitis severity or any other outcome. We found high-certainty evidence that forced expiratory techniques in infants with severe bronchiolitis do not improve their health status and can lead to severe adverse effects. Currently, the evidence regarding new physiotherapy techniques such as RRT or instrumental physiotherapy is scarce, and further trials are needed to determine their effects and potential for use in infants with moderate bronchiolitis, as well as the potential additional effect of RRT when combined with slow passive expiratory techniques. Finally, the effectiveness of combining chest physiotherapy with hypertonic saline should also be investigated.

Experience, facilitators, and barriers to the implementation of a multicomponent programme in older people living in the community, +AGIL Barcelona: A qualitative study.

Introduction: The +AGIL Barcelona programme is a multicomponent care intervention for frail older adults (FOAs) living in the community. To improve the programme, it is essential to investigate the experience of all participants. Our objective was to explore the perspective of FOA and professionals about the barriers, facilitators, and improvement elements of the development of the +AGIL Barcelona programme. Qualitative descriptive approach. Were included FOA and professionals who participated in the +AGIL Barcelona programme. Methods: Three focus groups and four interviews were conducted. These were analyzed following the qualitative method of content analysis. The criteria of scientific rigor of credibility, dependence, and transferability were ensured throughout the study. Results: Three themes and seven sub-themes were developed: facilitators (positive experience and perceived benefits), barriers (self-perceived health status, digital divide, and continuity of the programme at home), and improvements elements (programme continuity and adaptation of technology). All the participants felt satisfied, highlighting aspects such as interpersonal relationships and social contact, face-to-face sessions guided by a physiotherapist, and the functional improvement achieved. Some of the difficulties were the self-perception of frailty, the need for technological support, and continuing the exercise programme at home. Conclusion: The FOA who participated in the +AGIL Barcelona programme perceived direct benefits for their health and physical condition due to the development of self-confidence by being able to perform physical exercise despite their baseline condition, and the professionals experienced an improvement in the quality of care due to work in a multidisciplinary team.

Effectiveness of home-based exercise delivered by digital health in older adults: a systematic review and meta-analysis.

BACKGROUND: regular physical exercise is essential to maintain or improve functional capacity in older adults. Multimorbidity, functional limitation, social barriers and currently, coronavirus disease of 2019, among others, have increased the need for home-based exercise (HBE) programmes and digital health interventions (DHI). Our objective was to evaluate the effectiveness of HBE programs delivered by DHI on physical function, health-related quality of life (HRQoL) improvement and falls reduction in older adults. DESIGN: systematic review and meta-analysis. PARTICIPANTS: community-dwelling older adults over 65 years. INTERVENTION: exercises at home through DHI. OUTCOMES MEASURES: physical function, HRQoL and falls. RESULTS: twenty-six studies have met the inclusion criteria, including 5,133 participants (range age 69.5 ± 4.0-83.0 ± 6.7). The HBE programmes delivered with DHI improve muscular strength (five times sit-to-stand test, -0.56 s, 95% confidence interval, CI -1.00 to -0.11; P = 0.01), functional capacity (Barthel index, 5.01 points, 95% CI 0.24-9.79; P = 0.04) and HRQoL (SMD 0.18; 95% CI 0.05-0.30; P = 0.004); and reduce events of falls (odds ratio, OR 0.77, 95% CI 0.64-0.93; P = 0.008). In addition, in the subgroup analysis, older adults with diseases improve mobility (SMD -0.23; 95% CI -0.45 to -0.01; P = 0.04), and balance (SMD 0.28; 95% CI 0.09-0.48; P = 0.004). CONCLUSION: the HBE programmes carried out by DHI improve physical function in terms of lower extremity strength and functional capacity. It also significantly reduces the number of falls and improves the HRQoL. In addition, in analysis of only older adults with diseases, it also improves the balance and mobility.

Is there a learning effect on 1-min sit-to-stand test in post-COVID-19 patients?

The 1-min sit-to-stand test is a repeatable field test without differences between the first and second tests. Hence, conducting one attempt of the 1-min STST would be enough to evaluate functional capacity in patients recovered from #COVID19. https://bit.ly/3y3ycAP.

Exercise Capacity in Children and Adolescents With Congenital Heart Disease: A Systematic Review and Meta-Analysis.

Background: Congenital heart disease (CHD) entails structural defects in the morphogenesis of the heart or its main vessels. Analyzing exercise capacity of children and adolescents with CHD is important to improve their functional condition and quality of life, since it can allow timely intervention on poor prognostic factors associated with higher risk of morbidity and mortality. Objective: To describe exercise capacity in children and adolescents with CHD compared with healthy controls. Methods: A systematic review was carried out. Randomized clinical trials and observational studies were included assessing exercise capacity through direct and indirect methods in children and adolescents between 5 and 17 years-old. A sensitive analysis was performed including studies with CHD repaired participants. Additionally, it was sub-analyzed by age range (< and ≥ 12 years old). Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of the evidence. Results: 5619 articles were found and 21 were considered for the review. Eighteen articles used the direct exercise capacity measurement method by cardiopulmonary exercise test (CPET). The CHD group showed significant differences in peak oxygen consumption (VO2peak) with a value of -7.9 ml/Kg/min (95% CI: -9.9, -5.9, p = 0.00001), maximum workload (Wmax) -41.5 (95% CI: -57.9, -25.1 watts, p = 0.00001), ventilatory equivalent (VE/VCO2 ) slope 2.6 (95% CI: 0.3, 4.8), oxygen pulse (O2 pulse)-2.4 ml/beat (95% CI: -3.7, -1.1, p = 0.0003), and maximum heart rate (HRmax) -15 bpm (95% CI: -18, -12 bpm, p = 0.00001), compared with healthy controls. Adolescents (≥ 12 yrs) with CHD had a greater reduction in VO2peak (-10.0 ml/Kg/min (95% CI: -12.0, -5.3), p < 0.00001), Wmax (-45.5 watts (95% CI: -54.4, -36.7), p < 0.00001) and HRmax (-21 bpm (95% CI: -28, -14), p<0.00001). Conclusion: Suffering CHD in childhood and adolescence is associated with lower exercise capacity as shown by worse VO2peak, Wmax, VE/VCO2 slope, O2 pulse, and HRmax compared with matched healthy controls. The reduction in exercise capacity was greater in adolescents. Systematic Review Registration: www.crd.york.ac.uk/prospero/display_record.php?RecordID=208963, identifier: CRD42020208963.

Clinical Effects of Rehabilitation on Balance in People With Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

Background: Patients with chronic obstructive pulmonary disease (COPD) have systemic damage secondary to the primary pulmonary impairment, expressed in impaired peripheral musculature and a deficit in postural control compared to healthy subjects. This study aimed to determine the effects of rehabilitation on balance in patients with COPD. Methods: An exhaustive search was conducted in four databases (Pubmed, Cochrane Library, EMBASE, Web of Science). Articles with a population of COPD receiving rehabilitation (therapeutic exercise, pulmonary rehabilitation, or physical therapy modalities) in an outpatient setting were included. Two independent reviewers selected and assessed the study quality. The risk of bias was assessed with the Cochrane Risk of Bias Tool for Randomized Controlled Trials. Results: A total of eight studies involving 284 patients were included in the qualitative synthesis. The meta-analysis showed an overall result in favor of balance training for the Berg Balance Scale (mean difference 3.91 points; 95% CI: 1.51 to 6.31; P = 0.001), Timed Up and Go test (mean difference -1.58 s; 95% CI: -2.63 to -0.53; P = 0.003) and Unipedal stance test (mean difference 3.56 s, 95% CI: 2.58 to 4.54; P). Conclusion: This meta-analysis revealed that rehabilitation improve static and dynamic balance in patients with COPD. Systematic Review Registration: PROSPERO ID: CRD42020218367.

Respiratory Muscle Training in Patients with Obstructive Sleep Apnoea: A Systematic Review and Meta-Analysis.

Background: Effective treatments for obstructive sleep apnoea (OSA) include positive pressure, weight loss, oral appliances, surgery, and exercise. Although the involvement of the respiratory muscles in OSA is evident, the effect of training them to improve clinical outcomes is not clear. We aimed to determine the effects of respiratory muscle training in patients with OSA. Methods: A systematic review was conducted in seven databases. Studies that applied respiratory muscle training in OSA patients were reviewed. Two independent reviewers analysed the studies, extracted the data and assessed the quality of evidence. Results: Of the 405 reports returned by the initial search, eight articles reporting on 210 patients were included in the data synthesis. Seven included inspiratory muscle training (IMT), and one included expiratory muscle training (EMT). Regarding IMT, we found significant improvement in Epworth sleepiness scale in −4.45 points (95%CI −7.64 to −1.27 points, p = 0.006), in Pittsburgh sleep quality index of −2.79 points (95%CI −4.19 to −1.39 points, p < 0.0001), and maximum inspiratory pressure of −29.56 cmH2O (95%CI −53.14 to −5.98 cmH2O, p = 0.01). However, the apnoea/hypopnea index and physical capacity did not show changes. We did not perform a meta-analysis of EMT due to insufficient studies. Conclusion: IMT improves sleepiness, sleep quality and inspiratory strength in patients with OSA.

The Chester Step Test Is a Reproducible Tool to Assess Exercise Capacity and Exertional Desaturation in Post-COVID-19 Patients.

Many people recovering from an acute episode of coronavirus disease (COVID-19) experience prolonged symptoms. Exercise testing is a feasible and cost-effective option for assessing exercise tolerance, fatigue, and dyspnea related to effort. Being that the Chester step test (CST) is a progressive, submaximal test for predicting aerobic capacity, it could be a good option to explore. This study aimed to determine the reproducibility of CST for assessing exertional desaturation and exercise capacity in patients post-COVID-19 disease. A cross-sectional study was conducted on post-COVID-19 patients. Two attempts of the CST were performed. The intraclass correlation coefficient (ICC) was used to assess agreement between the two tests. Forty-two symptomatic post-COVID-19 patients were included, the mean age was 53.8 ± 10.3 years, and 52% were female. There was no significant difference between both tests (p = 0.896). Twenty-four percent of participants (10 cases) had a clinically significant decrease in SpO2 at the first assessment, compared to 30.1% (13 cases) at the second, with no significant difference. An ICC of 0.993 (95% CI: 0.987 to 0.996) was obtained for the total number of steps in the CST.

[Respiratory physiotherapy in post-COVID-19: a decision-making algorithm for clinical practice]. / Fisioterapia respiratoria post-COVID-19: algoritmo de decisión terapéutica.

The outbreak of COVID-19 has posed a great challenge for the healthcare system which has been later aggravated by the need of managing clinical manifestations and potential sequelae in COVID-19 survivors. In this context, respiratory Physiotherapy emerges as a cornerstone in the interdisciplinary management warranted in this population. Given that the implementation and resources available for the interdisciplinary therapeutic interventions in Spain is scarce, it is essential to perform a comprehensive, exhaustive and personalised assessment. This will allow us to establish more accurate selection criteria in order to optimise the use of existing human and material resources. To this end, we propose here a decision-making algorithm for clinical practice to assess the clinical manifestations in people recovered from COVID-19 based on well-established, validated tests and assessment tools. This algorithm can be used at any clinical practice environment (primary care/community or hospital-based), combined with a patient-centered model and the use of community and e-Health resources and its application to improve the Physiotherapy care of these patients in the COVID-19 era.

Effectiveness of a Primary Care Telerehabilitation Program for Post-COVID-19 Patients: A Feasibility Study.

In many health systems, it is difficult to carry out traditional rehabilitation programs as the systems are stressed. We evaluate the effectiveness of a telerehabilitation program conducted in primary care in post-COVID-19 patients. An observational, prospective study was conducted in seven primary care centers in Chile. We included adult patients (>18 years) with a previous SARS-CoV-2 infection. The telerehabilitation program consisted of 24 sessions of supervised home-based exercise training. The efficacy was measured by the 1-min sit-to-stand test (1-min STST), the 36-Item Short Form Health Survey (SF-36), fatigue, and dyspnea symptoms before and after intervention. We included 115 patients (55.4% female) with a mean age of 55.6 ± 12.7 years. Fifty-seven patients (50%) had antecedents of hospitalization, and 35 (30.4%) were admitted to the ICU. The 1-min STST was improved after the intervention from 20.5 ± 10.2 (53.1 ± 25.0%predicted) to 29.4 ± 11.9 (78.2 ± 28.0%predicted) repetitions (p < 0.001). The SF-36 global score improved significantly from 39.6 ± 17.6 to 58.9 ± 20.5. Fatigue and dyspnea improved significantly after the intervention. Although limited by the absence of a control group, this report showed that a telerehabilitation program applied in primary health care is feasible and was effective in improving physical capacity, quality of life and symptoms in adult survivors of COVID-19.

Effects of Exercise in Patients with Obstructive Sleep Apnoea.

Obstructive sleep apnoea (OSA) constitutes a public health problem, with various systemic consequences that can increase cardiovascular morbidity and mortality as well as increase healthcare expenditure. This review discusses the rationale and effects of using general physical exercise, oropharyngeal exercises, and respiratory muscle training as an adjunctive treatment for patients with sleep apnoea. The recommended treatment for OSA is the use of continuous positive airway pressure, which is a therapy that prevents apnoea events by keeping the airways open. In the last decade, coadjuvant treatments that aim to support weight loss (including diet and physical exercise) and oropharyngeal exercises have been proposed to lower the apnoea/hypopnoea index among patients with OSA. Based on the available evidence, health professionals could decide to incorporate these therapeutic strategies to manage patients with sleep apnoea.

Effect of pulmonary hypertension on exercise tolerance in patients with COPD: a prognostic systematic review and meta-analysis.

BACKGROUND: Pulmonary hypertension (PH) is a frequent complication in patients with COPD. OBJECTIVE: To determine if, in patients with COPD, the presence of PH decreases exercise tolerance. METHODS: We included studies that analysed exercise tolerance using a cardiopulmonary exercise test (CPET) in patients with COPD with PH (COPD-PH) and without PH (COPD-nonPH). Two independent reviewers analysed the studies, extracted the data and assessed the quality of the evidence. RESULTS: Of the 4915 articles initially identified, seven reported 257 patients with COPD-PH and 404 patients with COPD-nonPH. The COPD-PH group showed differences in peak oxygen consumption (V'O2peak ), -3.09 mL·kg-1·min-1 (95% CI -4.74 to -1.43, p=0.0003); maximum workload (Wmax), -20.5 W (95% CI -34.4 to -6.5, p=0.004); and oxygen pulse (O2 pulse), -1.24 mL·beat-1 (95% CI -2.40 to -0.09, p=0.03), in comparison to the group with COPD-nonPH. If we excluded studies with lung transplant candidates, the sensitivity analyses showed even bigger differences: V'O2 , -4.26 mL·min-1·kg-1 (95% CI -5.50 to -3.02 mL·kg-1·min-1, p<0.00001); Wmax, -26.6 W (95% CI -32.1 to -21.1 W, p<0.00001); and O2 pulse, -2.04 mL·beat-1 (95% CI -2.92 to -1.15 mL·beat-1, p<0.0001). CONCLUSION: Exercise tolerance was significantly lower in patients with COPD-PH than in patients with COPD-nonPH, particularly in nontransplant candidates.

Prevalence of potential respiratory symptoms in survivors of hospital admission after coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis.

Knowledge on the sequelae of Coronavirus Disease 2019 (COVID-19) remains limited due to the relatively recent onset of this pathology. However, the literature on other types of coronavirus infections prior to COVID-19 reports that patients may experience persistent symptoms after discharge. To determine the prevalence of respiratory symptoms in survivors of hospital admission after COVID-19 infection. A living systematic review of five databases was performed in order to identify studies which reported the persistence of respiratory symptoms in COVID-19 patients after discharge. Two independent researchers reviewed and analysed the available literature, and then extracted and assessed the quality of those articles. Of the 1,154 reports returned by the initial search nine articles were found, in which 1,816 patients were included in the data synthesis. In the pooled analysis, we found a prevalence of 0.52 (CI 0.38-0.66, p < 0.01, I2 = 97%), 0.37 (CI 0.28-0.48, p < 0.01, I2 = 93%), 0.16 (CI 0.10-0.23, p < 0.01, I2 = 90%) and 0.14 (CI 0.06-0.24, p < 0.01, I2 = 96%) for fatigue, dyspnoea, chest pain, and cough, respectively. Fatigue, dyspnoea, chest pain, and cough were the most prevalent respiratory symptoms found in 52%, 37%, 16% and 14% of patients between 3 weeks and 3 months, after discharge in survivors of hospital admission by COVID-19, respectively.

Levels of physical activity in children and adolescents with asthma: A systematic review and meta-analysis.

BACKGROUND: In children and adolescents with asthma, the disease may reduce the perceived capability to participate in physical activity (PA) contributing to an increase in the sedentary lifestyle. The literature is unclear as to whether children and adolescents with asthma differ their PA levels from their healthy peers. OBJECTIVE: Our objective was to describe the different methods and instruments used to measure PA and to compare the PA levels of children and adolescents with asthma with those of their healthy peers. STUDY DESIGN: We conducted a systematic review of five databases. We included studies that compared the PA measured by objective and subjective instruments in children and adolescents with asthma versus controls. Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of evidence. RESULTS: Of the 5966 reports returned by the initial search, 28 articles reporting on 3184 patients were included in the data synthesis. A forest plot showed that both groups had similar values of moderate to vigorous PA (MVPA; mean difference, -0.05 h/day; 95% confidence interval [CI], -0.11-0.01; p = .13), sedentary time (mean difference 0.00 h/day; 95% CI, -0.22-0.23 h/day; p = .99) and steps/day (mean difference 354 steps/day; 95% CI, -563-1270 steps/day; p = .45). CONCLUSION: Children and adolescents with asthma have similar MVPA, steps/day, and sedentary time compared to the controls. The main instruments used were questionnaires and accelerometers.

Physical Activity in Children and Adolescents With Chronic Respiratory Diseases: A Systematic Review and Meta-Analysis.

BACKGROUND: The literature is unclear as to whether children and adolescents with chronic respiratory diseases (CRDs) differ from their healthy peers in physical activity (PA). OBJECTIVE: To determine the PA levels measured through accelerometers in children and adolescents with CRDs. METHODS: The authors conducted a systematic review using five databases. The authors included studies that assessed the PA measured by accelerometers in children and adolescents with CRDs. Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of evidence. RESULTS: From 11,497 reports returned by the initial search, 29 articles reporting on 4381 patients were included. In the sensitivity analysis, the authors found that children and adolescents with CRDs had a moderate-to-vigorous PA (MVPA) of -0.08 hours per day (95% confidence interval [CI], -0.12 to -0.03 h/d; P = .001), which was lower than the healthy controls; the values for sedentary time (mean difference -0.47 h/d; 95% CI, -1.29 to 0.36 h/d; P = .27) and steps/d (mean difference 361 steps/d; 95% CI -385 to 1707 steps/d; P = .45) were similar for both. CONCLUSION: Children and adolescents with CRDs have a slight reduction in MVPA in comparison with healthy controls, but sedentary time and steps/d were similar for both.
