Effects of respiratory muscular training in post-covid-19 patients: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Post-Covid-19 syndrome is defined as non-self-sustaining signs and/or symptoms lasting more than 12 weeks, occurring during or after a Covid-19 infection. The primary outcome was the analysis of the respiratory muscle training (RMT) result in respiratory muscle strength, (maximum inspiratory pressure (MIP) e maximum expiratory pressure (MEP)); and the secondary results were the analysis of lung function, dyspnea, quality of life (QoL), fatigue and functional performance. METHODS: The PICO description for this research was: P: patients diagnosed with post-Covid-19; I: RMT; C: Sham or simulated inspiratory or expiratory muscle training and usual care; O: MIP, MEP, Lung Function, level of dyspnea, QoL and functional performance. On January 15, 2024, the following databases were consulted: PubMed, Lilacs, Cochrane Library, PEDro and EMBASE. Randomized clinical trials were included without restrictions on year of publication or language. The data selection and extraction steps were carried out by two independent reviewers. RESULTS: The search in the databases resulted in a total of 14,216 studies, and after the eligibility process, 7 studies were included with a sample of 527 patients. The MIP results suffered a statistically significant increase, that is, the RMT was favorable to improve the MIP (MD = 29.55cmH2O IC 95%: 7.56cmH2O to 51.54cmH2O, p = 0,00001). For the MEP outcome, the results were statistically significant in favor of RMT (MD = 10.93cmH2O CI 95%: 3.65cmH2O to 18.21cmH2O, p = 0.00001). We also noticed a significant improvement for the group that received the RMT in the distance covered in the 6-Minute Walk Test (6MWT) MD = 40.70 m CI 95%: 18.23 m to 65.17 m%, p = 0.01). CONCLUSION: We noticed that RMT is being used in patients with respiratory diseases, including post-Covid-19. Our systematic review observed that this training provides an increase in inspiratory and expiratory muscle strength, a reduction in dyspnea levels, and an increase in the distance covered in the 6MWT and improved QoL in post-covid patients after intervention.

The usefulness of patient-reported outcome measures in decision making in Chagas cardiomyopathy: a scoping review.

Chagas cardiomyopathy (ChC) presents many biopsychosocial complexities, highlighting the need to have patient self-report questions. This study demonstrates the scope of the use of patient-reported outcome measures (PROMs) in patients with ChC and highlights the main research gaps. This is a scoping review and the search strategy was performed in the Online Medical Literature Analysis and Retrieval System (MEDLINE), Excerpta Medica database (EMBASE), Accumulated Index of Nursing and Allied Health Literature (CINAHL), Cochrane Central, Latin American Literature and Caribbean in Health Sciences (LILACS) and Diagnostic Test Accuracy (DITA). The search identified 4484 studies and 20 studies met the inclusion criteria. The Short-Form of 36 items (SF-36) had potential prognostic value and the ability to identify systolic dysfunction. The Human Activity Profile was able to screen for functional impairment, and the New York Heart Association showed potential prognostic value. The SF-36 and Minnesota Living with Heart Failure Questionnaire were responsive to interventions. The pharmaceutical care affected adherence to treatment as assessed by the Morisky score and also for SF-36. Despite the increased use of PROMs, there are still a large number of gaps in the literature, and further studies using PROMs are needed.

Efficacy and safety of therapeutic strategies for human brucellosis: A systematic review and network meta-analysis.

BACKGROUND: Human brucellosis is a neglected, re-emerging, and endemic zoonosis in many countries. The debilitating and disabling potential of the disease is a warning about its morbidity, generating socioeconomic impact. This review aims to update the current evidence on the efficacy and safety of therapeutic options for human brucellosis using the network meta-analysis (NMA). METHODOLOGY: A systematic search was conducted in four different databases by independent reviewers to assess overall therapy failure, adverse events, and time to defervescence associated with different therapies. Randomized clinical trials (RCTs) evaluating any therapeutic drug intervention were selected, excluding non-original studies or studies related to localized forms of the disease or with less than 10 participants. Data were analyzed by frequentist statistics through NMA by random effects model. The risk of bias and certainty of evidence was assessed, this review was registered at PROSPERO. RESULTS: Thirty-one (31) RCTs involving 4167 patients were included. Three networks of evidence were identified to evaluate the outcomes of interest. Triple therapy with doxycycline + streptomycin + hydroxychloroquine for 42 days (RR: 0.08; CI 95% 0.01-0.76) had a lower failure risk than the doxycycline + streptomycin regimen. Doxycycline + rifampicin had a higher risk of failure than doxycycline + streptomycin (RR: 1.96; CI 95% 1.27-3.01). No significant difference was observed between the regimens when analyzing the incidence of adverse events and time to defervescence. In general, most studies had a high risk of bias, and the results had a very low certainty of evidence. CONCLUSIONS: This review confirmed the superiority of drugs already indicated for treating human brucellosis, such as the combination of doxycycline and aminoglycosides. The association of hydroxychloroquine to the dual regimen was identified as a potential strategy to prevent overall therapy failure, which is subject to confirmation in future studies.

Aquatic exercise for people with asthma: a systematic review with meta-analysis of randomized controlled trials.

INTRODUCTION: Aquatic exercises are among the types of exercise most tolerated by people with asthma. Therefore, the objective of this study was to synthesize the evidence on the effects of aquatic exercise on lung function and quality of life in asthmatic patients. DATA SOURCES: A systematic search encompassing the Medline, CINAHL, Cochrane Library, Embase, AMED, SPORTDiscus, and Physiotherapy Evidence Database databases was conducted to identify randomized controlled trials assessing the impact of aquatic exercise in comparison to control conditions or land-based exercise on lung function and quality of life in individuals diagnosed with asthma. STUDY SELECTIONS: The stages of selection, data extraction and methodological evaluation, and level of evidence of the manuscripts were carried out independently by two authors. RESULTS: Ten studies, comprising a total of 393 participants, were incorporated into this systematic review. Very low-quality evidence was found in favor of aquatic exercise in asthmatic patients for forced expiratory volume in 1 s (MD: 0.20 L, 95% CI: 0.02 L-0.38L N: 91) and for forced vital capacity (MD: 0.32 L, 95% CI: 0.08 L-0.56L N: 80). No effect of aquatic exercise was observed on the FEV1/FVC ratio (MD:1.11L, 95% CI: -1.28 L-3.49L N:80) compared with control. Only one study evaluated the effect of aquatic exercise on patients' quality of life. CONCLUSIONS: Improvements in lung function and quality of life in asthmatic patients undergoing aquatic exercise are not supported by high-quality evidence. The present findings will need to be confirmed by new, methodologically more rigorous clinical trials.

The effect of aquatic exercise on pulmonary function and quality of life in asthma patients is still uncertain.The current quality of evidence for aquatic exercise in asthma patients is low.There is an urgent need for higher-quality studies investigating the effects of aquatic exercise among asthma patients.

Home Based Rehabilitation in Children and Adolescents with Cystic Fibrosis: A Systematic Review with Meta-Analysis and Grade Recommendations.

OBJECTIVE: The objective of this study is to elucidate the effectiveness of home based rehabilitation (HBR) and compare its results with those obtained in conventional rehabilitation (CR) programs, carried out in clinics and/or outpatient clinics. METHODS: Searches were conducted in five databases of randomized clinical trials. Study selection, data extraction, and assessment of the methodological quality of included studies were conducted independently by two reviewers, with discrepancies resolved by a third reviewer. RESULTS: The results demonstrate post-intervention values favorable to the use of HBR when compared to control group in the outcomes of forced expiratory volume in 1 second (FEV1) (MD = 14% CI: 5.42 to 22.58, p = 0.001), forced vital capacity (FVC) (MD = 8.00% CI: 0.83 to 15.17, p = 0.03) and quality of life by the Cystic Fibrosis Questionnaire - revised in the categories (Child version score" (MD= 0.71%CI: 0.15 to 1.27, p = 0.01) and "Parent version score" (MD= 0.67%CI: 0.11 to 1.23, p = 0.02). Furthermore, we noticed an increase in the distance covered in the 6-minute walk test (MD= 34.75%CI: -8.00 to 77.50, p = 0.14), in favor of HBR. CONCLUSIONS: We found that supervised or partially supervised HBR promotes improvements in FEV1, FVC and related quality of life in children and/or adolescents with cystic fibrosis.

Health-Related Quality of Life Reported by Patients With Chagas Disease: A Systematic Review of Qualitative Evidence With GRADE Recommendations.

Patients with Chagas disease have reduced health-related quality of life (HRQoL). Hence, we aimed to identify the factors that mostly affected their HRQoL. This was a systematic review of qualitative studies. The Latin American and Caribbean Health Sciences Literature, Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Web of Science, and SciVerse Scopus databases were searched for relevant studies without language or date restrictions. The search and data analysis were performed by independent reviewers; all qualitative studies that reported the factors that had an impact on the HRQoL of patients with Chagas disease were included. The risk of bias was assessed using the Critical Appraisal Skills Program Qualitative Study Checklist; confidence in the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative approach. Five studies were included in this review: four in Brazil and one in California, United States, with immigrants from Central and South America. The sample consisted of 207 patients with chronic Chagas disease. Stigma, physical limitations, work absenteeism, emotional or mental aspects, fear of treatment, and fear of the future had the strongest impact on the HRQoL. All items showed moderate confidence except for fear of treatment (low confidence). The physical, emotional, mental, and cultural aspects affected the HRQoL of patients with chronic Chagas disease. Identification of these factors is important in the development of strategies aimed at improving the HRQoL of this population.

Plasma levels of soluble TNF receptors are associated with cardiac function in patients with Chagas heart disease.

BACKGROUND: The soluble receptors tumor necrosis factor-alpha (sTNFRs) can lead to an increase in the expression of tumor necrosis factor, increasing its detrimental to systemic inflammatory activation in Chagas cardiomyopathy (ChC). However, the correlation between sTNFRs levels, echocardiographic, and functional levels in patients with ChC remains unknown. This study aimed to verify the correlation between the plasma sTNFRs levels, echocardiographic, and NYHA functional levels in patients with ChC. METHODS: Sixty-four patients with ChD (54 ± 2 years, 44% males, NYHA I-II) were evaluated by anamnesis protocol, echocardiography, and plasma sTNFR1 and sTNFR2 measurement. Linear regression analysis and Student's t-test were used as appropriate. RESULTS: Higher plasma sTNFR1 and sTNFR2 levels were associate with worse systolic function (R2 = 0.10; p = 0.008 and R2 = 0.44; p < 0.001) and cardiac dilation (R2 = 0.13; p = 0.002 and R2 = 0.43; p < 0.001). Patients with systolic dysfunction and cardiac dilatation had higher sTNFRs levels (p < 0.001). There were no significant differences among NYHA functional classes for both sTNFRs. CONCLUSION: Plasma sTNFR1 and sTNFR2 levels are associated with greater cardiac dilation and poor systolic function in ChC patients.
