Comparative efficacy of different exercise methods to improve cardiopulmonary function in stroke patients: a network meta-analysis of randomized controlled trials.

Background: Although some studies have shown that exercise has a good effect on improving the cardiopulmonary function of stroke patients, it still needs to be determined which exercise method does this more effectively. We, therefore, aimed to evaluate the effectiveness of different exercise methods in improving cardiovascular function in stroke patients through a network meta-analysis (NMA), providing a basis to select the best treatment plan for stroke patients. Methods: We systematically searched CNKI, WanFang, VIP, CBM, PubMed, Embase, Web of Science, and The Cochrane Library databases from establishment to 30 April 2023. Randomized controlled trials (RCTS) on exercise improving cardiopulmonary function in stroke patients were included, and we screened the included articles and extracted the relevant data. RevMan (version 5.4) and Stata (version 17.0) were used for data analysis. Results: We included 35 RCTs and a total of 2,008 subjects. Intervention measures included high-intensity interval training (HIIT), aerobic training (AT), resistance training (RT), combined aerobic and resistance exercise (CE), and conventional therapy (CT). In the network meta-analysis, the surface under the cumulative ranking area (SUCRA) ranking result indicated that HIIT improved peak oxygen uptake (VO2peak) and 6 mins walking distance (6MWD) optimally, with rankings of HIIT (100.0%) > CE (70.5%) > AT (50.2%) > RT (27.7%) > CT (1.6%), and HIIT (90.9%) > RT (60.6%) > AT (48.9%) > RT (48.1%) > CT (1.5%), respectively. The SUCRA ranking result showed that CE improved systolic blood pressure (SBP) and diastolic blood pressure (DBP) optimally, with rankings of CE (82.1%) > HIIT (49.8%) > AT (35.3%) > CT (32.8%), and CE (86.7%) > AT (45.0%) > HIIT (39.5%) > CT (28.8%), respectively. Conclusion: We showed that exercise can effectively improve the cardiopulmonary function of stroke patients. HIIT was the most effective in improving VO2peak and 6MWD in stroke patients. CE was the most effective in improving SBP and DBP in stroke patients. However, due to the limitations of existing clinical studies and evidence, larger sample size, multi-center, and high-quality RCTs are needed to verify the above conclusions in the future.

Effect of early stepwise cardiopulmonary rehabilitation on function and quality of life in sepsis patients.

BACKGROUND: Sepsis, as a non-limiting host infection disease, can be accompanied by serious complications such as organ failure, which seriously threatens patient quality of life. AIM: To investigate the effect of early stepwise cardiopulmonary rehabilitation on cardiopulmonary function and quality of life in patients evacuated from mechanical ventilation with sepsis. METHODS: A total of 80 patients with sepsis who were hospitalized in our hospital from January 2021 to January 2022 were selected and divided into the observation group (n = 40) and the control group (n = 40) according to the random number table method. The observation group was treated with early stepwise cardiopulmonary rehabilitation, and the control group was treated with a conventional treatment regimen. Cardiac function indexes (central venous pressure, cardiac troponin I, B-type brain natriuretic peptide), lung function indicators (diaphragmatic mobility, changes in central venous oxygen saturation, oxygenation index), and quality of life (Quality of Life Evaluation Scale) were compared between the two groups after treatment. RESULTS: After treatment, the central venous pressure, diaphragm mobility, central venous oxygen saturation, oxygenation index, and Quality of Life Evaluation Scale scores in the observation group were higher than those in the control group, and the differences were statistically significant (P < 0.05). The observation group was less than that of the control group for other parameters, and the differences were statistically significant (P < 0.05). CONCLUSION: Early stepwise cardiopulmonary rehabilitation can effectively enhance cardiac and pulmonary function and improve the quality of life in patients evacuated from mechanical ventilation with sepsis.

Effect of different intensity exercises on cardiopulmonary function and quality of life of patients with chronic heart failure : A systematic review and meta-analysis.

BACKGROUND: Exercise-based cardiac rehabilitation has positive benefits for patients with chronic heart failure (CHF), but the choice of exercise intensity has been controversial. The aim of this systematic review and meta-analysis was to investigate the effects of different exercise intensities on cardiopulmonary function and quality of life (QoL) of patients with CHF. METHODS: Randomized controlled trials (RCTs) of different exercise intensities applied to patients with CHF were searched in PubMed, Web of Science, the Cochrane Library, and Embase databases from inception to December 2021. Study selection and data extraction were performed simultaneously by two independent reviewers, using the Physiotherapy Evidence Database Scale (PEDro) for quality assessment of the included literature. The weighted mean differences (WMD) or standardized mean difference (SMD) were calculated by employing a fixed or random effects model. Other statistical analyses included subgroup analysis and sensitivity analysis. Quality of evidence was evaluated by the Grade of Recommendation, Assessment, Development, and Evaluation (GRADE) method. RESULTS: Eight RCTs were included. Analyses reported no significant improvement in left ventricular ejection fractions (LVEF; WMD = 0.47, 95% CI [-4.10, 5.03], p = 0.841), peak oxygen uptake (peak VO2) (SMD = 0.38, 95% CI [-0.03, 0.80], p = 0.069) and 6­min walking distance (6MWD) (WMD = 14.10, 95% CI [-9.51, 37.72], p = 0.242). Exercise interventions of varying intensity produced small-to-moderate beneficial effects on QoL (WMD = -4.99, 95% CI [-8.29, -1.68], p = 0.003), which appeared to be attenuated at long-term follow-up (WMD = 2.12, 95% CI [-2.91, 7.16], p = 0.409). CONCLUSION: High-intensity exercise does not have a significant advantage over moderate-intensity exercise in improving cardiopulmonary function and aerobic capacity in patients with CHF. Beneficial changes in QoL from high-intensity exercise also appeared to decrease during long-term follow-up, indicating a cumulative effect of the efficacy of high-intensity exercise.

Effect of a Conical-PEP Mask on Exercise in Subjects With COPD.

BACKGROUND: Dynamic hyperinflation (DH) is a major pathophysiology of COPD that is directly related to dyspnea and exercise intolerance. Positive expiratory pressure (PEP) might reduce DH and dyspnea during exercise, but at present, there is insufficient evidence to conclude whether it is beneficial for DH, dyspnea, and exercise capacity in COPD. METHODS: A randomized crossover trial with concealed allocation was conducted in 37 moderate to very severe subjects with COPD (34 males, age 66.6 ± 7.4 y, FEV1% of predicted 56.3 ± 13.7). The experimental condition was conical-PEP breathing with a PEP of around 5 cm H2O during a spot marching exercise at a constant speed, inducing 71 ± 9% age-predicted maximum heart rate to symptom limit or 25 min. The control condition was usual breathing. Exercise endurance time and end-exercise symptoms were recorded. Inspiratory capacity (IC) was measured pre-exercise and immediately post exercise. Cardiopulmonary function and breathlessness were monitored throughout the test and after 10 min of recovery. RESULTS: There were no complications or adverse effects during exercise with a conical-PEP mask. Conical-PEP showed longer exercise times than control (median 11.0 [interquartile range 7.7-17.0] min vs 8 [6.0-11.5] min, respectively, P < .001). Most stopped exercising because of breathlessness and leg fatigue. At the end of exercise, IC and breathlessness showed non-significant differences between the conditions, but breathlessness was significantly lower in conical-PEP (median 4 [1.5-5.0] than control 5 [3-6] on Borg scale at isotime for control [8 min]). CONCLUSIONS: Breathing with a 5 cm H2O conical-PEP mask improved exercise time (median 27.1% [0.6-52.9]) in subjects with COPD. The improvement in exercise with the conical-PEP mask was associated with slower development of breathlessness, possibly due to delays in DH development.

Exercise for chronic kidney disease: effects on vascular and cardiopulmonary function.

Patients with chronic kidney disease (CKD) have an exacerbated prevalence of cardiovascular disease (CVD). Vascular dysfunction, characterized by impaired endothelial function and arterial stiffness, and markedly low cardiorespiratory fitness levels are hallmark manifestations of the disease that contribute to the CVD burden. Despite advancements in blood pressure and lipid lowering pharmacological therapies, CVD remains markedly prevalent across the spectrum of CKD. This highlights a stagnation in effective clinical strategies to improve cardiovascular health and reinforces the critical need for adjuvant lifestyle strategies such as physical activity and exercise training to be incorporated into routine clinical care. This narrative review provides an overview of the known effects of exercise on vascular and cardiopulmonary function across the spectrum of CKD. The physiological mechanisms of vascular dysfunction that serve as exercise-specific therapeutic targets are highlighted and future perspectives are discussed.

The application value of lung ultrasound scoring in assessing disease severity: Evaluation of small-scale outbreaks of COVID-19.

PURPOSE: This study explored the use of transthoracic lung ultrasound for evaluating COVID-19 patients, compared it with computed tomography (CT), and examined its effectiveness using 8 and 12 lung regions. METHODS: A total of 100 patients with COVID-19 and 40 healthy volunteers were assessed using 12 regions (bilateral upper/lower regions of the anterior/lateral/posterior chest) and simplified 8 zones (bilateral upper/lower regions of the anterior/lateral chest) transthoracic lung ultrasound. The relationships between ultrasound, CT, and clinical indicators were analyzed to evaluate the diagnostic value of ultrasound scores in COVID-19. RESULTS: Increased disease severity correlated with increased 8- and 12-zone ultrasound and CT scores (all p < 0.05). The modified 8-zone method strongly correlated with the 12-zone method (Pearson's r = 0.908, p < 0.05). The 8- and 12-zone methods correlated with CT scoring (correlation = 0.568 and 0.635, respectively; p < 0.05). The intragroup correlation coefficients of the 8-zone, 12-zone, and CT scoring methods were highly consistent (intragroup correlation coefficient = 0.718, p < 0.01). The 8-zone ultrasound score correlated negatively with oxygen saturation (rs = 0.306, p < 0.05) and Ca (rs = 0.224, p < 0.05) and positively with IL-6 (rs = 0.0.335, p < 0.05), erythrocyte sedimentation rate (rs = 0.327, p < 0.05), alanine aminotransferase (rs = 0.230, p < 0.05), and aspartate aminotransferase (rs = 0.251, p < 0.05). The 12-zone scoring method correlated negatively with oxygen saturation (rs = 0.338, p < 0.05) and Ca (rs = 0.245, p < 0.05) and positively with IL-6 (rs = 0.354, p < 0.05) and erythrocyte sedimentation rate (rs = 0.495, p < 0.05). CONCLUSION: Lung ultrasound scores represent the clinical severity and have high clinical value for diagnosing COVID-19 pneumonia. The 8-zone scoring method can improve examination efficiency and reduce secondary injuries caused by patient movement.

The effects of rate pressure product at admission on cardiopulmonary function during hospitalization in patients with acute myocardial infarction.

OBJECTIVE: This study aimed to analyze the correlation between the rate pressure product (RPP) and cardiopulmonary function during hospitalization in patients with acute myocardial infarction (AMI). METHODS: A total of 362 patients with AMI were selected for the study, and the median admission RPP was used as the cutoff point to divide the patients into a low-RPP group (n = 181) and a high-RPP group (n = 181). The relationship between the RPP at admission and the cardiopulmonary function during hospitalization was analyzed. RESULTS: The patients in the high-RPP group had a higher body mass index (BMI) (p = 0.014), a higher prevalence of combined hypertension and diabetes mellitus (p < 0.001), a lower incidence of smoking (p = 0.044), and a higher incidence of oscillatory ventilation (6.1% vs. 1.7%, p = 0.029). The differences in RPP at rest, during warm-up, and within 1 and 4 minutes of recovery were statistically significant between the two groups (p < 0.01 on each occasion), while the differences in anaerobic threshold (AT) and watt max (Max) were not statistically significant (p > 0.05 for both). The patients in the low-RPP group had higher oxygen uptake (VO2 [AT]: 14.9 ± 3.4 vs. 14.2 ± 3.6, p = 0.048) and (VO2peak [Max]:18.2 ± 3.8 vs. 17.3 ± 3.8, p = 0.020). The RPP at admission was negatively correlated with VO2 (AT) and VO2peak (p < 0.05) using the regression Equation VO2peak = 33.682 + (-0.012 * RPP at admission/100) + (-0.105 * Age) + (-0.350 * BMI), while there was no correlation between the RPP at admission and VO2 (AT) (p = 0.149). CONCLUSION: The RPP at admission was negatively correlated with cardiopulmonary function during hospitalization in patients with AMI. Patients with a high RPP were more likely to have a combination of obesity, hypertension, diabetes mellitus, and reduced oxygen uptake during exercise, while a high RPP at admission appeared to affect their cardiovascular response indicators during exercise.

Factors associated with failure of cardiopulmonary function recovery after lung cancer surgery.

BACKGROUND AND OBJECTIVE: This study aimed to evaluate the longitudinal changes in cardiopulmonary function (CPF) and identify predictors of cardiopulmonary recovery failure after lung cancer surgery. METHODS: Data was obtained from a prospective CATCH-LUNG cohort study, where patients were divided into two groups based on 6-min walk distance (6MWD) at baseline and 6 months after surgery. CPF recovery failure was defined as a participant whose 6MWD dropped over 50 m from baseline to 6 months after surgery. Patients with a baseline 6MWD less than 400 m were excluded. The analysis was investigated using mixed effects models, and the relative estimates for the predictors were expressed relative risk (RR) and 95% CI using a Poisson regression. RESULTS: Among 419 patients, 24.1% and 17.7% showed failure of CPF recovery at 6 months and 1 year after surgery, respectively. In the multivariable analysis, baseline step count [RR per 1000 steps lower = 1.05 (95% CI, 1.01-1.09)], baseline dyspnoea [RR per 10 points higher = 1.15(1.07-1.23)], decreased FEV1 % predicted from baseline to 2 weeks after surgery [RR per 10% lower = 1.30(1.10-1.53)] and decreased moderate-to-vigorous physical activity (MVPA) from baseline to 2 weeks [RR = 1.95(1.22, 3.11)] or persistent low MVPA at baseline and 2 weeks after surgery [RR = 1.63(1.04, 2.54)] were significant factors for loss of CPF. CONCLUSION: The inability to recover CPF at 6 months after surgery was linked to reduction of lung function and MVPA from baseline to 2 weeks as well as baseline physical activity (PA) and dyspnoea. These results imply that engagement of perioperative PA is necessary to facilitate recovery of CPF after lung cancer surgery.

A randomized controlled crossover trial of acute intermittent and continuous hypoxia exposure in mild-moderate obstructive sleep apnea: A feasibility study.

In a prospective, randomized, controlled crossover study, we explored the effects of acute intermittent hypoxia and acute continuous hypoxia on patients with mild-moderate obstructive sleep apnea. Over three single-night sessions, subjects were alternately exposed to normoxia, acute continuous hypoxia and acute intermittent hypoxia before sleep. The apnea-hypopnea index and oxygen desaturation index were used to diagnose obstructive sleep apnea and evaluate efficacy. A responder was defined as a participant with a ≥ 50% reduction in apnea-hypopnea index between normoxia and hypoxia exposure. Sixteen participants with mild-moderate obstructive sleep apnea completed the study. Compared with normoxia, the mean apnea-hypopnea index decreased by 8.9 events per hr (95% confidence interval, 4.2-13.6, p = 0.001) with acute intermittent hypoxia and by 4.1 events per hr (95% confidence interval, 0.5-8.8, p = 0.082) with acute continuous hypoxia, equating to a mean decrease in apnea-hypopnea index of 4.8 events per hr (95% confidence interval, 0.1-9.5, p = 0.046) with acute intermittent hypoxia compared with acute continuous hypoxia. Compared with normoxia, the mean oxygen desaturation index decreased by 9.8 events per hr (95% confidence interval, 4.4-15.1, p = 0.001) with acute intermittent hypoxia but did not significantly decrease with acute continuous hypoxia; the mean oxygen desaturation index decreased by 7.2 events per hr (95% confidence interval, 1.8-12.6, p = 0.010) with acute intermittent hypoxia compared with acute continuous hypoxia. Of the 16 participants, 11 responded to acute intermittent hypoxia and four responded to acute continuous hypoxia (p = 0.032), of whom eight of 11 cases and all four cases had oxygen desaturation indexes <5 events per hr, respectively (p = 0.273). All participants tolerated acute intermittent hypoxia and there were no obvious adverse events during acute intermittent hypoxia exposure. In conclusion, acute intermittent hypoxia exposure improved apnea-hypopnea index and oxygen desaturation index in patients with mild-moderate obstructive sleep apnea, suggesting that further prospective validation of intermittent hypoxia exposure in patients with obstructive sleep apnea is needed to establish its clinical feasibility as a therapeutic modality.

Changes in Exercise Tolerance over Time in Patients with Transthyretin Amyloidosis Cardiomyopathy Treated with Tafamidis.

Tafamidis improves the prognosis of patients with transthyretin amyloidosis cardiomyopathy (ATTR-CM). Additionally, it delays the decline in exercise tolerance, as observed in the six-minute walking test. However, the changes in cardiopulmonary function over time based on cardiopulmonary exercise tests are unclear. Thus, this preliminary study investigated the changes in exercise tolerance after one year of tafamidis treatment using cardiopulmonary exercise testing. Eight patients with ATTR-CM (average age: 77 years; male: n = 7) underwent cardiopulmonary exercise testing at baseline and after one year of tafamidis treatment. All eight patients completed a one-year follow-up. At baseline, the anaerobic threshold oxygen uptake (AT VO2: 10.9 ± 1.5) and peak VO2 (14.3 ± 3.0 mL/kg/minute) indicated relatively favorable exercise capacity; however, the minute ventilation/carbon dioxide production (VE/VCO2 slope), which indicates effective ventilation, showed poor performance (33.7 ± 12.8). One year after tafamidis treatment, frailty, as assessed by the Clinical Frailty Scale, had progressed in seven of eight patients (88%) (P < 0.01), and AT VO2 and peak VO2 were significantly reduced (19.2% and 22.3%, respectively; P < 0.05). The VE/VCO2 slope and peak O2 pulse decreased nonsignificantly by approximately 20% (P = 0.47, and P = 0.16, respectively). Further, the structure of the ventricles and atrium and the left ventricle ejection fraction on echocardiography did not change. Thus, exercise tolerance in patients with ATTR-CM was reduced after one year despite tafamidis administration. Not only ATTR-CM progression, but also frailty progression may influence this decrease in exercise tolerance. A comprehensive approach, including tafamidis administration and cardiac rehabilitation, is required for further improvement in the exercise capacity of patients with ATTR-CM.

To Weed or Not to Weed: A Systematic Review Exploring the Potential for Cannabis Use in Cardiovascular Disease, Mental Health and Pain Management.

Despite its historical reputation as a substance of abuse, cannabis use has increased following decriminalization efforts in the United States. It has historically garnered a bad reputation as a substance of abuse, but paradoxically is associated with an improved perception of well-being. We were interested in positive cardiovascular outcomes, both positive and negative mental health outcomes and impact on physical activity of cannabis, both recreational and medical. Databases included PubMed, ResearchGate, Cochrane, Science.gov and ScienceDirect. We were interested in cardiovascular, mental health and physical health in our search. Data included articles published during or after 2017. Our studies showed no cardiovascular benefits, increased risk of documented cardiovascular events and increased mortality associated with cannabis use. Physical benefits derived were largely in patients with chronic pain. With regards to mental health, the impact of the drug appears to be both positive and negative, with no clear benefits as a first-line agent. Route of administration appears to have an impact on the overall extent of side effects. Overall, medical cannabis appears to pose an almost negligible side effect profile compared to recreational. Our findings suggest that while cannabis use may offer benefits for chronic pain management, it is associated with increased cardiovascular risks. Further, medical cannabis appears to have a more favorable side effect profile compared to recreational use.

Effect of large volume red blood cell apheresis on cardiovascular functions in healthy donors.

BACKGROUND: Requirements of blood transfusions rise rapidly in China. Improving the efficiency of blood donation could help maintaining sufficient blood supplement. We conducted a pilot research to investigate the reliability and safety of collecting more units of red blood cell by apheresis. METHODS: Thirty-two healthy male volunteers were randomized into two groups: red blood cell apheresis (RA) (n = 16) and whole blood (WB) donation (n = 16). RA group donated individualized RBC volumes by apheresis according to the volunteers' basal total blood volumes and haematocrit levels, WB group donated 400 mL whole blood. All volunteers were scheduled seven visit times in 8 weeks' study period. The cardiovascular functions were assessed by laboratory examinations, echocardiography and cardiopulmonary functional tests. All results were compared between groups at the same visit time and compared between visit 1(before donation) and other visit times within the same group. RESULTS: The average donated RBC volume in RA group and in WB group was 627.25 ± 109.74 mL and 175.28 ± 8.85 mL, respectively(p < 0.05); the RBC, haemoglobin and haematocrit levels changed significantly between times and between groups (p < 0.05). Cardiac biomarker levels such as NT-proBNP, hs-TnT and CK-MB did not change significantly between times or between groups (p > 0.05). The echocardiographic and cardiopulmonary results did not change significantly between times or between groups during the whole study period(p > 0.05). CONCLUSIONS: We provided an efficient and secure method for RBC apheresis. By harvesting more RBC volumes at one single-time, the cardiovascular functions did not change significantly compared with traditional whole blood donation.

Correlation of fundamental movement skills with health-related fitness elements in children and adolescents: A systematic review.

Objective: To examine the correlations between fundamental movement skills and health-related fitness elements (cardiopulmonary function, flexibility, body composition, muscle strength and endurance) in children and adolescents and investigate the evaluation methods and tools of fundamental movement skills and health-related fitness. Methods: Six electronic databases (Web of Science, PubMed, ProQuest, Scopus, EBSCO and CNKI) were searched, and the research literature on the correlation between children's and adolescents' fundamental movement skills and health-related fitness published since 2002 was collected. The guidelines of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement and the Consolidated Standards of Reporting Trials (CONSORT) statement were used to evaluate the quality of the literature, and the sources, samples, measurement methods, main results and statistical data of the study were analyzed, summarized and discussed. Results: After applying the inclusion and exclusion criteria, 49 studies were included. There were 13 tools for evaluating fundamental movement skills and 4 tools for evaluating comprehensive health-related fitness in the included literature. Sufficient research evidence supports a significant positive correlation between fundamental movement skills and cardiopulmonary function (10, 100%) and muscle strength and endurance (12, 100%), and most studies support the positive correlation between fundamental movement skills and flexibility (4, 66.7%), and the significant negative correlation between fundamental movement skills and body composition (29, 67.4%). Studies used skinfold, AF%, BF%, FM, and FFMI as evaluation methods. They showed a consistently significant negative correlation between body composition and fundamental movement skills (9, 100%), while BMI or waist circumference as evaluation methods showed no consistent significant negative correlation result (20, 58.8%). Moreover, in the sub-item evaluation of fundamental movement skills, object manipulation, locomotor and balance skills were all significantly and positively correlated with cardiopulmonary function and muscle strength and endurance. In contrast, locomotor skills were more closely related to body composition than object manipulation skills. Conclusion: A significant correlation exists between children's and adolescents' fundamental movement skills and health-related fitness elements.

Effects of different exercise modalities on inhibiting left ventricular pathological remodeling in patients with heart failure with reduced ejection fraction: A systematic review and network meta-analysis.

AIMS: To evaluate the effects of different exercise training modalities on inhibiting the left ventricular pathological remodeling in patients with heart failure with reduced ejection fraction (HFrEF) and screen out the optimal exercise modality. METHODS: We performed a network meta-analysis based on the Frequentist model. Random-effect meta-analyses were used to estimate mean differences (MD) and 95 % confidence intervals. KEY FINDINGS: 25 randomized controlled trials (1284 patients) were enrolled in this study. Results revealed that: high-intensity interval training had the best effect in improving left ventricular ejection fraction (p-score = 0.93, MD: 6.44 (3.61 to 9.28)), reducing left ventricular end-diastolic diameter (p-score = 0.97, MD: -6.73 (-10.27 to -3.19)) and left ventricular end-systolic diameter (p-score = 0.97, MD: -9.33 (-14.90 to -3.76)). Combined aerobic training with resistance training and inspiratory muscle training had the best effect in improving maximal oxygen consumption (p-score = 0.90, MD: 5.19 (3.12 to 7.25)). SIGNIFICANCE: Current evidence revealed that exercise training could effectively inhibit left ventricular pathological remodeling in patients with HFrEF. For efficacy, high-intensity interval training may have greater potential.

Therapeutic Effects of Metaverse Rehabilitation for Cerebral Palsy: A Randomized Controlled Trial.

Metaverse physical therapy (MPT), an adjuvant technology for the rehabilitation of children with cerebral palsy (CP), has gained notoriety in the clinical field owing to its accessibility and because it provides motivation for rehabilitation. The aim is to compare the gross motor function and cardiopulmonary function, the activities of daily living, quality of life (QOL), and the perceived risk of coronavirus disease (COVID)-19 transmission between MPT and conventional physical therapy (CPT). A convenience sample of 26 children with CP (mean age, 11.23 ± 3.24 years, 14 females) were randomized into either the MPT or CPT group and received therapy three days/week for four weeks. Clinical outcomes included gross-motor-function measure 66 (GMFM-66), heart rate (HR), Borg-rating perceived exertion (BRPE), functional independence measure (FIM), pediatric QOL, and the risk of COVID-19 transmission. An analysis of variance showed that compared with CPT, MPT exerted positive effects on GMFM, HR, and BRPE. An independent t-test showed that compared with CPT, MPT exerted positive effects on the perceived transmission risk of COVID-19 but not on FIM and QOL. Our results provide promising therapeutic evidence that MPT improves gross motor function, cardiopulmonary function, and the risk of COVID-19 in children with CP.

The Greifswald Post COVID Rehabilitation Study and Research (PoCoRe)-Study Design, Characteristics and Evaluation Tools.

(1) Background: COVID-19 is often associated with significant long-term symptoms and disability, i.e., the long/post-COVID syndrome (PCS). Even after presumably mild COVID-19 infections, an increasing number of patients seek medical help for these long-term sequelae, which can affect various organ systems. The pathogenesis of PCS is not yet understood. Therapy has so far been limited to symptomatic treatment. The Greifswald Post COVID Rehabilitation Study (PoCoRe) aims to follow and deeply phenotype outpatients with PCS in the long term, taking a holistic and comprehensive approach to the analysis of their symptoms, signs and biomarkers. (2) Methods: Post-COVID outpatients are screened for symptoms in different organ systems with a standardized medical history, clinical examination, various questionnaires as well as physical and cardiopulmonary function tests. In addition, biomaterials are collected for the analysis of immunomodulators, cytokines, chemokines, proteome patterns as well as specific (auto)antibodies. Patients are treated according to their individual needs, adhering to the current standard of care. PoCoRe's overall aim is to optimize diagnostics and therapy in PCS patients.

Impact of diabetes on cardiopulmonary function: the added value of a combined cardiopulmonary and echocardiography stress test.

Type 2 diabetes mellitus (T2DM) represents a major health issue worldwide, as patients with T2DM show an excess risk of death for cardiovascular causes, twice as high as the general population. Among the many complications of T2DM, heart failure (HF) deserves special consideration as one of the leading causes of morbidity and reduced life expectancy. T2DM has been associated with different phenotypes of HF, including HF with reduced and preserved ejection fraction. Cardiopulmonary exercise testing (CPET) can evaluate the metabolic and ventilatory alterations related to myocardial dysfunction and/or peripheral impairment, representing a unique tool for the clinician to study the whole HF spectrum. While CPET allows for a thorough evaluation of functional capacity, it cannot directly differentiate central and peripheral determinants of effort intolerance. Combining CPET with imaging techniques could provide even higher accuracy and further insights into the progression of the disease since signs of left ventricular systolic and diastolic dysfunction can be detected during exercise, even in asymptomatic diabetic individuals. This review aims to dissect the alterations in cardiopulmonary function characterising patients with T2DM and HF to improve patient risk stratification.

Inspiratory muscle training improves cardiopulmonary function in patients after transcatheter aortic valve replacement: a randomized clinical trial.

AIMS: Inspiratory muscle training (IMT) can increase the strength or endurance of the diaphragm and accessory muscles of inspiration, yet there is no evidence that endorses the role of IMT in patients of transcatheter aortic valve replacement (TAVR). This study for the first time tested the effects of IMT plus usual cardiac rehabilitation (CR) function in patients after TAVR. METHODS AND RESULTS: A double-blinded, randomized controlled, single-centre clinical trial was undertaken. Participants who had a confirmed diagnosis of valve heart disease and were clinically stable after TAVR were recruited and received a CR programme during the hospital stay. A total of 96 patients were recruited and randomly assigned to the IMT + CR group (n = 48) or the CR group (n = 48) in a 1:1 ratio. The group difference in the primary outcome, the 6-min walk distance at the discharge of the hospital, significantly favoured the IMT + CR group (mean difference -33.52, 95% CI: -64.42 to -2.62, P = 0.034). The significant difference was maintained at the 1-month and 3-month follow-ups (mean difference: 41.51, 95% CI: 1.82-81.21, P = 0.041). In addition, the mean hospital stays of subjects in the IMT + CR group was 11 days, which was significantly shorter than the 12.5 days in the CR group (P = 0.016). Sensitivity analysis using per-protocol analysis supported these findings. No adverse treatment-related events were reported. CONCLUSION: Compared with usual CR, IMT plus CR can effectively improve exercise endurance, pulmonary ventilation function, and inspiratory muscle strength in patients after TAVR and shorten the length of hospital stay.

Effect of high-intensity interval training on cognitive weakness in elderly patients with coronary heart disease / 中国实用护理杂志

Objective:To investigate the effect of high-intensity interval training on cognitive weakness in elderly patients with coronary heart disease.Methods:A randomized controlled study was used. A total of 70 elderly patients with coronary heart disease after discharge from the Cardiology Department, Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from June 2020 to June 2021 were selected and divided into the control group (35 cases) and the observation group (35 cases) by random digits table method. The control group received conventional treatment, and the observation group received high-intensity interval training on the basis of conventional treatment. The changes of peak oxygen intake (PeakVO 2), anaerobic threshold oxygen uptake (ATVO 2), Fried phenotype score, Montreal Cognitive Assessment score, and SF-36 quality of life assessment score before and after 12 weeks of intervention were compared between the two groups. Results:During the intervention, 2 cases fell off in the control group and 2 cases in the observation group. After 12 weeks of intervention, PeakVO 2 and ATVO 2 in the observation group were (23.91 ± 5.88), (20.79 ± 5.19) ml·min -1·kg -1, respectively, higher than those in the control group(20.56 ± 5.81), (17.29 ± 5.36) ml·min -1·kg -1, and the differences were statistically significant ( t = 2.38, 2.69, both P<0.05). The scores of SF-36 quality of life assessment and Montreal Cognitive Assessment in the observation group were (85.33 ± 6.43), (22.64 ± 3.81) points, which were significantly higher than those in the control group (78.72 ± 8.14), (20.67 ± 3.04) points, and the differences were statistically significant ( t = 3.66, 2.32, both P<0.05); the Fried phenotype score in the observation group was (1.36 ± 0.99) points, which was significantly lower than that in the control group (3.03 ± 1.08) points, and the difference was statistically significant ( t = 6.54, P<0.05). Conclusions:High-intensity interval training can improve cardiopulmonary function, aerobic exercise ability, cognitive weakness and quality of life in elderly patients with coronary heart disease.
