IMPROVE-BMT: A Pilot Randomized Controlled Trial of Prehabilitation Exercise for Adult Hematopoietic Stem Cell Transplant Recipients.

Background: There is limited evidence on the effects of aerobic and resistance training exercise interventions to improve physical function and patient-reported outcomes prior to autologous and allogeneic hematopoietic stem cell transplant (HSCT). IMPROVE-BMT was a single-site, pilot randomized controlled trial investigating the feasibility, acceptability, and safety of a pragmatic resistance training exercise program prior to HSCT compared to usual HSCT care. Secondary aims included differences in physical function between the exercise group (EX) and usual care control group (UC). Methods: Outcome measurements were assessed: prior to HSCT, on/around day of HSCT admission, +30 days post-HSCT, and +100 days post-HSCT. The exercise intervention was a home-based exercise program that incorporated resistance-band and bodyweight exercises. Results: Acceptability among participants was 83%; exercise adherence averaged at 92%; and there were zero exercise-related adverse or serious adverse events. The average pre-transplant exercise phase was 6.28 weeks (2.71-18.29 weeks). EX (n = 36) demonstrated larger increases in the six-minute walk test distance, short physical performance battery scores, and 30-s chair stands compared to UC (n = 38) and demonstrated significant within-group improvements for the six-minute walk test, the short physical performance battery, the 30-s chair stands, and the timed up-and-go test. Conclusions: IMPROVE-BMT demonstrates that pragmatic exercise is highly feasible for HSCT recipients and can potentially lead to enhanced recovery that may not be achievable in non-exercisers.

Effects of aerobic exercise on children's executive function and academic performance: A systematic review and meta-analysis

ObjectiveTo investigate the effects of exercise on executive function in children, providing an evidence-based foundation to inform future research in school physical education and health education. MethodsWe searched ten databases: Cochrane Library, Scopus, OVID, Web of Science, PubMed, EBSCOhost, SPORTDiscus, PsycINFO, CNKI, WANFANG DATA, VIP, and SinoMed, and eight articles were included. Applying the revised Cochrane Risk of Bias Tool for Randomized Trials (RoB2), funnel plots and Egger regression analysis were integrated with R meta-analysis to screen for publication bias. The quality of the evidence was appraised using the Grading system. ResultsThe included literature contained 2655 participants, with 1308 in the experimental group and 1347 in the control group. The results indicated that the aerobic exercise group considerably improved inhibitory control in children compared to the control group [SMD = 0.29, 95% CI (0.05, 0.54), P = 0.018]; working memory [SMD = 0.25, 95% CI (0.07, 0.42), P = 0.005]; and cognitive flexibility [SMD = 0.36, 95% CI (0.17, 0.54), P < 0.001]. However, the findings indicated that only aerobic exercise interventions extending beyond 50 weeks positively influenced academic performance in children [SMD = 1.19, 95% CI (0.34, 2.04), P = 0.006]. The results of an Egger regression analysis revealed that the p-values for inhibitory control, working memory, cognitive flexibility, and academic performance were more significant than 0.1. The Grade system said that the quality of evidence was all low regarding the level of evidence. ConclusionAerobic exercise enhanced executive function but only aerobic exercise interventions extending beyond 50 weeks demonstrated a significant effect on the academic performance of children. Due to the low quality of evidence presented in this study, additional high-quality randomized controlled trials are needed to confirm these findings.

Inhibition of SPARC signal by aerobic exercise to ameliorate atherosclerosis

Background and aimsInflammation and atherosclerosis (AS) are closely associated to Secreted Protein Acidic and Rich in Cysteine (SPARC) and its related factors. This study attempted to define the role and the potential mechanism of SPARC and its related factors in ameliorating hyperlipidemia and AS by aerobic exercise intervention. MethodsThe AS rat model was established with a high-fat diet plus vitamin D3 intraperitoneal injection. Treadmill exercises training (5 days/week at 14 m/min for 60 min/day) for 6 weeks was carried out for AS rat intervention method. Western blotting and qRT-PCR were used to analyze the mRNA and protein expression of SPARC and its related factors, respectively. H&E staining was applied to evaluate the morphological changes and inflammation damage. Von Kossa staining was used to measure the degree of vascular calcification. Fluorescence immunohistochemistry staining was used to detect the expression and distribution of SPARC signal molecules. ResultsSPARC was highly expressed and co-localization with the smooth muscle marker α-SMC in the AS rat. And its downstream factors, NF-κB, Caspase-1, IL-1β and IL-18 were upregulated (P < 0.05 or P < 0.01), FNDC5 expression was downregulated in AS rat model. However, slight declined body weight, delayed AS progression, decreased hyperlipidemia and favorable morphology of skeletal muscle and blood vessels have been detected in AS rat with aerobic exercise intervention. Moreover, the expression of SPARC and its downstream factors were decreased (P < 0.05 or P < 0.01), while elevated the expression of FNDC5 (P < 0.01) was observed after aerobic exercise intervention. ConclusionsThis study suggested that aerobic exercise ameliorated hyperlipidemia and AS by effectively inhibiting SPARC signal, and vascular smooth muscle cells may contribute greatly to the protection of AS.

Abstract 6290: Effects of a circuit, interval-based exercise program on vascular function among cancer survivors

Abstract Background: Cancer survivors are at an increased risk of cardiovascular comorbidity, including atherosclerosis, hypertension, and heart failure, due to negative impacts of cancer treatments on vascular function. Exercise is recommended in recent cardio-oncology rehabilitation guidelines and has been shown to improve vascular function in clinical populations; however, its effects on vascular function are understudied in clinical oncology settings. Purpose: This pilot study examined whether a circuit, interval-based exercise intervention can improve vascular function, assessed by brachial artery flow-mediated dilation (baFMD) and carotid intima media thickness (cIMT) in breast, prostate, and colorectal cancer survivors. Methods: Overweight or obese (BMI&amp;gt;25.0 kg/m2), sedentary breast, prostate or colorectal cancer survivors were randomized to exercise (n=60) or usual care (n=30). Survivors in the 4-month exercise intervention trained three times/week, in a circuit, interval-based supervised moderate-vigorous aerobic (65-85% of VO2max) and resistance (65-85% of 1-repetition maximum) program. cIMT and baFMD were measured at baseline and post-intervention via an ultrasound. Paired t-tests and repeated-measures analysis of variance were run to assess within- and between-group differences. Results: The study sample included breast (n=38), prostate (n=24), colorectal (n=28) cancer survivors who were 63.2 ± 10.8 years old, completed chemotherapy and/or radiation (75%) and were obese (87%). Post-intervention, baFMD significantly increased in the exercise group compared to the control group (between-group mean difference: 6.3%; 95% CI: [1.9 to 9.3], p=0.001). There was also a significant reduction in cIMT in the exercise group compared to the control group (between-group mean difference: -0.039mm, 95% CI: [-0.080 to -0.009], p=0.002). Conclusions: Our findings in this pilot study support that a circuit, interval-based aerobic and resistance exercise intervention may improve vascular function in breast, prostate, and colorectal cancer survivors. Future studies are recommended to understand how exercise interventions can be utilized clinically to improve cardiovascular disease risk and co-morbidity among cancer survivors.

Aerobic Exercise Modulates Proteomic Profiles in Gastrocnemius Muscle of db/db Mice, Ameliorating Sarcopenia.

Type-2 diabetes mellitus (T2DM)-induced sarcopenia is intertwined with diminished insulin sensitivity and extracellular matrix (ECM) remodeling in skeletal muscle and other organs. Physical activities such as aerobic exercise play a crucial role in regulating blood glucose levels, insulin sensitivity, metabolic pathways, oxidative stress, fibrosis, ECM remodeling, and muscle regeneration by modulating differentially expressed protein (DEP) levels. The objectives of our research were to investigate the effect of six weeks of aerobic exercise on the gastrocnemius and soleus muscle of db/db mice's DEP levels compared to those of sedentary db/db mice. A total of eight db/db mice were divided into two groups (n = 4 per group), namely sedentary mice (SED) and exercise-trained mice (ET), of which the latter were subjected to six weeks of a moderate-intensity aerobic exercise intervention for five days per week. After the exercise intervention, biochemical tests, including analyses of blood glucose and HbA1c levels, were performed. Histological analysis using H & E staining on tissue was performed to compare morphological characters. Gastrocnemius and soleus muscles were dissected and processed for proteomic analysis. Data were provided and analyzed based on the DEPs using the label-free quantification (LFQ) algorithm. Functional enrichment analysis and Ingenuity Pathway Analysis (IPA) were employed as bioinformatics tools to elucidate the molecular mechanisms involved in the DEPs and disease progression. Significantly reduced blood glucose and HbA1c levels and an increased cross-sectional area (CSA) of gastrocnemius muscle fibers were seen in the ET group after the exercise interventions due to upregulations of metabolic pathways. Using proteomics data analysis, we found a significant decrease in COL1A1, COL4A2, ENG, and LAMA4 protein levels in the ET gastrocnemius, showing a significant improvement in fibrosis recovery, ECM remodeling, and muscle regeneration via the downregulation of the TGF-β signaling pathway. Upregulated metabolic pathways due to ET-regulated DEPs in the gastrocnemius indicated increased glucose metabolism, lipid metabolism, muscle regeneration, and insulin sensitivity, which play a crucial role in muscle regeneration and maintaining blood glucose and lipid levels. No significant changes were observed in the soleus muscle due to the type of exercise and muscle fiber composition. Our research suggests that engaging in six weeks of aerobic exercise may have a positive impact on the recovery of T2DM-induced sarcopenia, which might be a potential candidate for mitigation, prevention, and therapeutic treatment in the future.

Exercise positively impacts global longitudinal strain in women at risk of developing cardiovascular disease

AbstractCardiovascular (CV) disease accounts for one third of deaths in females, with hypertension (HTN) and type 2 diabetes mellitus (T2DM) risk factors for its development. Global longitudinal strain (GLS) is a strong prognostic indicator for future CV dysfunction and can be impaired in women with HTN and T2DM. This study aimed to determine if exercise impacts GLS in women with HTN or T2DM. A randomized crossover trial was conducted with 15 women (aged 64.1 ± 4.7) diagnosed with HTN (n = 12) or T2DM (n = 3). Participants completed an 8‐week exercise and 8‐week non‐exercising control period, separated by a 21.6 ± 14.2‐week washout period. Resting echocardiography and exercise testing were performed pre and post each arm to measure GLS and aerobic fitness (VO2peak). GLS (%) improved significantly following exercise (−16.8 ± 1.5 to −18.4 ± 1.8; p ≤ 0.001, d = 0.98), but not control (−17.2 ± 2.0 to −16.9 ± 1.4; p = 0.585, d = −0.14). Similarly, VO2peak (mL/kg/min) increased following exercise (18.0 ± 2.1 to 19.2 ± 2.6; p ≤ 0.001, d = 0.53), but not control (17.5 ± 2.7–17.2 ± 2.7; p = 0.269, d = −0.12). There were significant between‐group differences for GLS (p ≤ 0.001, d = 1.02) and VO2peak (p = 0.011, d = 0.63). Aerobic exercise positively impacts GLS and VO2peak in women with HTN and T2DM. GLS may inform exercise professionals regarding the early effectiveness of an aerobic exercise intervention and infer a reduction in CV disease risk.

Research on adults with subthreshold depression after aerobic exercise: a resting-state fMRI study based on regional homogeneity (ReHo).

Subthreshold depression (StD)/subsyndromal depression refers to a threatening precursor to depression. Aerobic exercise is a promising self-supportive adjunctive intervention and an effective measure for StD. Our study utilizes regional homogeneity (ReHo) to investigate the impact of aerobic exercise on resting-state brain function. A total of 78 subjects, aged between 18 and 48 years, (StD group, n = 44; healthy control (HC) group, n = 34) engaged in moderate-intensity aerobic exercise 3-4 times per week for 8 weeks. Resting-state brain function and structural images were acquired before and after the exercise intervention. The ReHo method was employed to analyze abnormal changes in regional brain function, and a correlation analysis was performed using the Patient Health Questionnaire-9 (PHQ-9) and Self-Rating Anxiety Scale (SAS) scores. The principal observation reveals synchronous abnormalities in the right anterior cingulate gyrus of the brain in StD subjects compared to HCs at baseline, with these differences dissipating after the implementation of aerobic exercise. After completing the aerobic exercise program, the StD group exhibited a difference in the right middle cingulate gyrus, while the left supplementary motor area (SMA) was altered in the HC group. Disparities in neural synchronization are evident between HCs and StD subjects, and the implementation of aerobic exercise intervention can effectively mitigate these distinctions, leading to a significant reduction in depressive symptoms among StD subjects. The primary mechanism of StD symptoms may involve the inhibition of the anterior cingulate gyrus, while the effects of aerobic exercise may be related to the modulation of neural synchronization of emotional reflexes. The discovery of these fMRI evidence findings may offer novel strategies for early detection and intervention in cases of StD.

Acute aerobic exercise at different intensities modulates inhibitory control and cortical excitability in adults with attention-deficit hyperactivity disorder (ADHD)

BackgroundThis study aimed to investigate the effects of different aerobic exercise intensities on inhibitory control and cortical excitability in adults with attention-deficit/hyperactivity disorder (ADHD). MethodsThe study was conducted in a within-subject design. Twenty-four adults with ADHD completed a stop signal task and received cortical excitability assessment by transcranial magnetic stimulation (TMS) before and after a single session of low-, moderate-, high-intensity aerobic exercise or a control intervention. ResultsAcute moderate-, and high-intensity aerobic exercise improved inhibitory control in adults with ADHD. Moreover, the improving effect was similar between moderate-, and high-intensity aerobic exercise conditions. As shown by the brain physiology results, short interval intracortical inhibition was significantly increased following both, moderate- and high-intensity aerobic exercise intervention conditions. Additionally, the alteration of short interval intracortical inhibition and inhibitory control improvement were positively correlated. ConclusionsThe moderate-, and high-intensity aerobic exercise-dependent alterations of cortical excitability in adults with ADHD might partially explain the inhibitory control-improving effects of aerobic exercise in this population.

Effect of aerobic exercise on anthropometric parameters among Indian primary school children.

Childhood obesity is a global public health concern with significant implications for long-term health. This study addresses the rising rates of obesity among school-age children (10-12 years) and investigates the effectiveness of aerobic exercise interventions in improving anthropometric parameters, specifically focusing on BMI and mid-arm circumference (MAC). The study emphasizes the role of schools in shaping children's behaviors and aims to contribute empirical evidence to inform health promotion strategies for this demographic. The research employs a quasi-experimental design, involving 60 school-age children in Visnagar, Gujarat, India. The 12-week aerobic exercise intervention, conducted three times a week, comprises activities like running, jumping jacks, and dance routines. Data collection includes sociodemographic information, BMI, and MAC measurements. The study design, participant criteria, and intervention details are carefully outlined. Socio-demographic variables such as age and monthly family income significantly influence BMI, highlighting the importance of considering these factors in interventions. Pretest results show 80% of children classified as overweight, reducing to 58.3% post-intervention. The mean BMI significantly decreases from 24.41 to 22.84 (p < 0.05), indicating the positive impact of aerobic exercise. The study also explores the association between BMI, MAC, and socio-demographic variables through chi-square tests. Data shows the prevalence of overweight and obesity among school-age children and demonstrates the effectiveness of a 12-week aerobic exercise program in improving BMI. Findings align with existing literature on the positive impact of physical activity on weight management in children.

Cognitive Enhancement Strategies for Older Adults: An Evaluation of Different Training Modalities to Improve Executive Function-A Systematic Review and Meta-Analysis.

(1) Background: The aging population is expected to triple by 2050. Executive functions decline with age, impacting daily tasks, and this is associated with neurodegenerative diseases. Aerobic and resistance exercises positively affect cognitive function in older adults by influencing growth markers. However, the modalities of exercise and the optimal parameters for maximum cognitive benefits remain unclear. (2) Methods: A meta-analysis of randomized clinical trials (RCTs) was conducted. The systematic search was on slowing cognitive decline and performed in the PubMed/MEDLINE and Cochrane Library databases. Articles were included if participants were ≥65 years, healthy, and performing resistance or aerobic exercise, and they were excluded if there was a combination of training and if they have neurological disease or cognitive impairment. (3) Results: The search strategy found a total of 1635 studies. After removing duplicates and assessing the inclusion and exclusion criteria, eight articles were included in the meta-analysis, with a total of 463 healthy older adults analyzed. No significant differences between the intervention groups and the control groups after the aerobic or resistance programs were found. (4) Conclusions: Aerobic exercise interventions improved executive function more than resistance training in older adults, but without statistically significant differences. This can serve as a guide to see, with caution, whether we need a multidisciplinary approach to be more effective in improving the cortical health of older adults.

Alleviating Stress in Parkinson's Disease: Symptomatic Treatment, Disease Modification, or Both?

Psychological stress, a state of mental strain caused by mentally or physically threatening situations, plays a significant role in Parkinson's disease (PD). Motor symptoms worsen during acute stress and common non-motor symptoms in PD, such as anxiety and depression, are linked to chronic stress. Although evidence in humans is lacking, animal models of PD suggest that chronic stress can accelerate dopaminergic cell death. This suggests that stress-reducing interventions have not only symptomatic, but perhaps also disease-modifying effects. Our objective was to identify the most promising strategies for stress-reduction in PD and to analyze their potential value for disease-modification. An unstructured literature search was performed, primarily focusing on papers published between 2020-2023. Several large clinical trials have tested the efficacy of aerobic exercise and mindfulness-based interventions on PD symptoms. The evidence is promising, but not definitive yet: some exercise trials found a reduction in stress-related symptoms, whereas others did not or did not report it. In the majority of trials, biological measures of stress and of disease progression are missing. Furthermore, follow-up periods were generally too short to measure disease-modifying effects. Hence, mechanisms underlying the intervention effects remain largely unclear. These effects may consist of attenuating progressive neurodegeneration (measured with MRI-markers of substantia nigra integrity or cortical thickness), or a strengthening of compensatory cerebral mechanisms (measured with functional neuroimaging), or both. Lifestyle interventions are effective for alleviating stress-related symptoms in PD. They hold potential for exerting disease-modifying effects, but new evidence in humans is necessary to fulfill that promise.

Abstract 121: Improvements in Cardiovascular Fitness Following Forced-Rate Aerobic Cycling in Individuals With Chronic Stroke

Introduction: Declines in cardiovascular function in individuals following stroke result in increased energy costs of movement, restrictions in participation, and increased risk for recurrent stroke and other cardiovascular diseases. We have developed a rehabilitation model that incorporates aerobic exercise training to harness its potential neuroplastic effects. Our aim is to identify the cardiovascular benefits from a forced-rate aerobic exercise (FE) intervention among individuals with chronic stroke compared to an upper extremity repetitive task practice (UE RTP) control group. Hypothesis: We hypothesized that FE would elicit greater improvements in cardiovascular fitness compared to the UE RTP intervention. Methods: A randomized clinical trial was conducted in which participants (N=60) completed 24 sessions over 8 weeks of FE followed by RTP (FE+RTP) or time-matched RTP alone. The FE+RTP group exercised at 60-80% of heart rate reserve on a motorized stationary semi-recumbent cycle ergometer for 45 minutes followed by 45 minutes of RTP. The control group completed 90 minutes of RTP. Metabolic exercise stress tests were conducted at baseline and post-intervention. Outcomes included peak oxygen consumption (peak VO2) and anaerobic threshold (AT). Results: Fifty participants completed the study intervention and pre/post stress tests. The FE+RTP group demonstrated significantly greater improvements in peak VO2 from 16.4±5.7 to 18.3±6.4 mL/min/kg compared to the RTP group (17.0±5.6 to 17.2±5.6 mL/min/kg, p=0.020) and significantly greater improvements in AT from 10.3±2.8 to 11.5±3.6 mL/min/kg compared to the RTP group (10.8±3.9 to 10.4±3.2 mL/min/kg, p=0.020). Conclusions: An aerobic exercise intervention integrated into rehabilitation was effective in eliciting significant and meaningful improvements in cardiovascular fitness. This novel rehabilitation model may be an effective approach to improve motor and cardiovascular function.

Aerobic exercise protects MI heart through miR-133a-3p downregulation of connective tissue growth factor.

To investigate the effect of aerobic exercise intervention to inhibit cardiomyocyte apoptosis and thus improve cardiac function in myocardial infarction (MI) mice by regulating CTGF expression through miR-133a-3p. Male C57/BL6 mice, 7-8 weeks old, were randomly divided into sham-operated group (S group), sham-operated +aerobic exercise group (SE group), myocardial infarction group (MI group) and MI + aerobic exercise group (ME group). The mice were anesthetized the day after training and cardiac function was assessed by cardiac echocardiography. Myocardial collagen volume fraction (CVF%) was analyzed by Masson staining. Myocardial CTGF, Bax and Bcl-2 were detected by Western blotting, and myocardial miR-133a-3p was measured by RT-qPCR. Compared with the S group, miR-133a-3p, Bcl-2 and EF were significantly decreased and CTGF, Bax, Bax/ Bcl-2, Caspase 3, Cleaved Caspase-3, LVIDd, LVIDs and CVF were significantly increased in the MI group. Compared with the MI group, miR-133a-3p, Bcl-2 and EF were significantly increased, cardiac function was significantly improved, and CTGF, Bax, Bax/ Bcl-2, Caspase 3, Cleaved Caspase-3, LVIDd, LVIDs and CVF were significantly decreased in ME group. The miR-133a-3p was significantly lower and CTGF was significantly higher in the H2O2 intervention group compared with the control group of H9C2 rat cardiomyocytes. miR-133a-3p was significantly higher and CTGF was significantly lower in the AICAR intervention group compared to the H2O2 intervention group. Compared with the control group of H9C2 rat cardiomyocytes, CTGF, Bax and Bax/Bcl-2 were significantly increased and Bcl-2 was significantly decreased in the miR-133a-3p inhibitor intervention group; CTGF, Bax and Bax/Bcl-2 were significantly decreased and Bcl-2 was significantly upregulated in the miR-133a-3p mimics intervention group. Aerobic exercise down-regulated CTGF expression in MI mouse myocardium through miR-133a-3p, thereby inhibiting cardiomyocyte apoptosis and improving cardiac function.

Research on the Impact of Breathing Exercises and Aerobic Exercises on Quality of Life in Patients with Bronchial Asthma: A Comparative Study

Background: Asthma is defined as a chronic inflammatory disorder of airways characterized by reversible airflow obstruction causing cough, wheeze, chest tightness and shortness of breath Crompton et al7Asthmatic attacks are set up by exposure to specific allergens such as house dust mite, pollen and animal dander. Some other factors are exercise particularly running, dyes, air pollution, infection, cigarette smoke, dry inhaled air, certain foods such as fish, eggs, yeast, and wheat which presumably reach the bronchi via blood stream. There is noticeable increase in healthcare burden from asthma in several areas of world .The most frequently mentioned aims of breathing exercises are to ‘normalize’ breathing pattern by adopting a slower respiratory rate with longer expiration and reduction of hyperventilation and hyperinflation. Training also frequently involves encouraging nasal breathing and a diaphragmatic breathing pattern.AQLQ AND SF36 questionnaire was used as outcome measure.Methods: The sample size of this study was 30 subjects with 15 subjects in each group. The group A was given breathing exercises interventions and group B was given aerobic exercises intervention. A written consent was taken from each before their participation into the study. Asthma Quality of Life Questionnaire (AQLQ) and SF-36 quality of life Questionnaire of both the groups were taken in 0 week and both groups were assigned treatment interventions and after 3 weeks the AQLQ and SF-36 quality of life questionnaire has been repeated.The independent variables in the study were Aerobic Exercises and Breathing Exercises.Conclusion: The breathing exercise intervention was effective in improving the quality of life in asthmatic patients.The aerobic exercise intervention was also effective in improving the quality of life in asthmatic patients.However, the quantum of reduction in lung obstruction and therefore, the overall improvement in quality of life found to be more significant with the aerobic exercise intervention than breathing exercise intervention. Thus,a combination of the breathing exercises and aerobic exercise should be incorporated into the pulmonary rehabilitation program of the asthmatic patients.

Effects of aerobic exercise or Tai Chi Chuan interventions on problematic mobile phone use and the potential role of intestinal flora: A multi-arm randomized controlled trial

BackgroundProblematic use of mobile phones (PMPU) has been described as a serious public health issue. MethodsThis study was a parallel three-arm randomized controlled trial and has completed registration (ClinicalTrials.gov Identifier: NCT05843591). Ninety college students with PMPU were randomly assigned to the aerobic exercise group (AE group, n = 30), the Tai Chi Chuan group (TCC group, n = 30), or the wait-list control group (WLC group, n = 30). At the end of the intervention, stool samples from the study participants were collected for biological analysis based on 16 S rDNA amplicon sequencing technology. The primary outcome was addiction symptoms assessed by the Smartphone Addiction Scale-Short Version (SAS-SV). The secondary outcomes are emotional symptoms, physical symptoms, and flora species. ResultsCompared with the WLC group, the AE and TCC groups showed reductions in PMPU levels, physical and mental fatigue, but there was no difference between the two groups. Moreover, the effect of increasing self-esteem embodied in the TCC group was not present in the AE group. Compared to the WLC group, the relative abundance of Bacteroidaceae and Bacteroides were lower in the AE group, while the relative abundance of Erysipelotrichaceae and Alistipes were lower in the TCC group. And the relative abundance of Bacteroidaceae, Bacteroides, and Alistipes were significantly and negatively correlated with the decline in PMPU scores. ConclusionAE or TCC is an effective, safe and efficient intervention for college students with PMPU, providing some physiological and psychological benefits and having some impact on their intestinal flora.

Efficacy and feasibility of aerobic exercise interventions as an adjunctive treatment for patients with schizophrenia: a meta-Analysis

Schizophrenia is a chronic mental disorder primarily treated with antipsychotics, which have limited efficacy for negative symptoms. This study aims to evaluate the effectiveness and feasibility of exercise interventions as adjuncts to pharmacotherapy through a meta-analysis, providing valuable insights for rational intervention design. Four databases were searched, and randomized controlled trials with no language restrictions published up to March 27, 2023, were included. The primary outcome indicator was the Positive and Negative Symptom Scale (PANSS) total score along with its three sub-scales. Secondary outcomes included the Scale for Assessment of Negative Symptoms (SANS) and Body Mass Index (BMI), which were used to assess the efficacy of aerobic exercise interventions in patients with schizophrenia. Subgroup analyses were conducted to explore the impact of intervention duration and total weekly exercise time, while treatment feasibility was assessed through adherence rates. A total of 17 publications involving 973 patients with schizophrenia were deemed eligible and included in the analysis. Compared to other forms of adjunctive interventions, the network meta-analysis of 12 PANSS-based studies revealed that adjunctive aerobic exercise interventions were the most effective in reducing overall PANSS scores in patients with schizophrenia, with statistically significant pooled results (MD = −4.84, 95% CI: −5.72, −3.96). Both the PANSS negative symptom subscale (MD = −2.11, 95% CI: −3.26, −0.95) and SANS (MD = −9.11, 95% CI: −11.94, −6.27) indicated that adjunctive aerobic exercise interventions effectively alleviate negative symptoms. Subgroup meta-analysis indicated that 2-3 month interventions involving 100–220 min of exercise per week were the most effective. Additionally, adherence to the adjunctive aerobic exercise regimen was found to be comparable to that of conventional treatment alone. Aerobic exercise interventions, as adjunctive therapy, are an effective measure for reducing PANSS scores in patients with schizophrenia, contributing to the alleviation of both the positive and negative symptoms, and patients demonstrated strong adherence to aerobic exercise.

Effects of different early cardiac rehabilitation exercise treatments on the prognosis of acute myocardial infarction patients receiving percutaneous coronary intervention

ObjectivesExercise rehabilitation is the core of Cardiac Rehabilitation (CR) and will improve the prognosis of patients receiving Percutaneous Coronary Intervention (PCI surgery). The current study retrospectively analyzed the effects of different exercise-based CR strategies on the prognosis of AMI patients receiving PCI treatment. MethodsClinicopathological information from 127 patients was collected and divided into different groups based on the exercise-based CR received, including Continuous Resistance Exercise (COR), Continuous Aerobic Exercise (COA), Interval Resistance Exercise (IVR), Interval Aerobic Exercise (IVA), Inspiratory Muscle Exercises (ITM), and Control. The differences regarding cardio-pulmonary function, hemodynamics, and life quality were analyzed against different CR strategies. ResultsAll the exercise-based CR strategies showed improving effects compared with patients in the Control group regarding cardio-pulmonary parameters, with IVR showing the strongest improving effects (IVR > ITM > COR > IVA > COA) (p < 0.05) at the first recoding point. However, the improving effects of exercise-based CR declined with time. Regarding the effects on hemodynamics parameters, the improving effects of exercise-based CR were only observed regarding LVEF, and the effects of IVR were also the strongest (IVR > COR > ITM > COA > IVA) (p < 0.05). Similar improving effects were also observed for 6MWT and life quality (IVR showing the strongest improving effects) (p < 0.05), which all declined three months after the surgery. ConclusionsThe current study showed that exercise-based CRs had better improving effects than the normal nursing strategy on the prognosis of AMI patients receiving PCI surgery.

Landscape and impact of mind-body, cognitive-behavioral, and physical activity interventions in adolescent and adult brain tumor patients: A systematic review.

The use of mind-body, cognitive-behavioral, and physical activity interventions have shown efficacy for improving symptom burden and functional limitations in other cancers; however, these strategies have not been widely implemented within neuro-oncology. This systematic review describes the current landscape and the impact of these interventions on adolescent and adult patients with brain tumors, which may guide the development of future interventions. A systematic search of PubMed, Embase, and Web of Science was performed using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines with predefined eligibility criteria. Twenty-nine studies met the inclusion criteria and were selected for review. There was promising evidence for the feasibility and efficacy of mind-body and physical activity interventions for improving mood and quality of life, as well as enhanced physical functioning following aerobic and strength-based interventions. Results were mixed for cognitive-behavioral interventions, likely due to underpowered analyses. Interventions tested in pediatric patients also showed improvements in fatigue, mood, and quality of life, though these individuals represented a small proportion of the pooled sample. Findings suggest that mind-body and physical activity interventions can improve both physical and psychological health for patients with brain tumors, though additional well-designed clinical trials are needed to better establish efficacy.

Acute and Chronic Effects of Interval Aerobic Exercise on Hepcidin, Ferritin, and Liver Enzymes in Adolescents With Beta-Thalassemia Major.

This study aimed to determine the acute and chronic effects of interval aerobic exercise on hepcidin, ferritin, and liver enzymes in adolescents with beta-thalassemia major. Twenty-six beta-thalassemia major adolescents referred to the Thalassemia Clinic and Research Center were selected as study participants and randomly divided into control (n = 13) and training (n = 13) groups. Participants performed 3 sessions per week for 45minutes in each session for 8 weeks of aerobic interval exercise with an intensity of 50% to 65% of the heart rate reserve. Blood samples were taken before, immediately after the exercise session, and 48hours after the last training session, and liver enzymes aspartate aminotransferase, alanine aminotransferase (ALT), alkaline phosphatase (ALP), ferritin, and hepcidin were evaluated. The results showed a decrease in aspartate aminotransferase, ALT, ALP, ferritin, and hepcidin levels due to 8 weeks of aerobic interval training (P = .14, P = .97, P = .03, P < .001, P < .001; respectively). Intergroup changes in all variables except ALT and hepcidin were significant (P < .05). Besides, acute aerobic exercise increased levels of aspartate aminotransferase, ALT, ferritin, and hepcidin (P = .04, P = .52, P < .001, P < .001; respectively), whereas ALP levels decreased (P < .001). In addition, changes in ALP and hepcidin levels were significant between the 2 groups (P = .05, P < .001; respectively). Based on the study's results, it can be concluded that 8 weeks of aerobic interval training can decrease ferritin and hepcidin levels, but acute aerobic exercise increases them.
