Functional Exercise Research Articles

Scientometric analysis of articles of respiratory gas mixtures and their application in emergency medicine

Relevance. In humans, specific respiratory gas mixtures (RGMs) significantly maximize the effect of anesthesia and treatment of certain diseases, as well as enhance body functional reserves and exercise performance. The objective is to identify major research prospects on the RGM capacity to optimize the functional status of humans, as represented in publications by Russian investigators.Methods. In response to the RGMs query, the Scientific Electronic Library search engine generated a dataset of 513 publications by Russian investigators, published from 2006 to 2023. For further analysis of the publications, the VOSviewer 1.6.20 software was implemented for clustering of keywords with a frequency of ≥ 4 presented in ≥ 8 publications either by individual authors or co-authorship networks.Results and discussion. The average annual number of articles was (23 ± 3). The dynamics of increasing publications were revealed. The scientometric analysis of the selected publications revealed that the content was highly demanded among readers. For instance, the average citation number per paper was 3.29, with a substantial self-citation rate of 30.2 %. Journals with the largest number of publications by top scientific networks were identified. The VOSviewer analysis produced 7 keyword clusters: Cluster 1 for xenon anesthesia – 258 papers (35 %) with the total link strength of 29 %; Cluster 2 for hypoxic training – 171 papers (23.2%) with the total link strength of 22.5 %; Cluster 3 for gas composition in confined spaces – 76 papers (10.3 %) and 22 % total link strength; Cluster 4 for oxygen-helium gas mixture – 132 papers (17.9 %) with 16.4 % total link strength; Cluster 5 for the neuroprotective effects of gas mixtures – 32 papers (4.3 %) with 3.6 % total link strength; Cluster 6 for the anti-stress effect of xenon-rich inhalation therapy – 40 papers (5.4 %) with 3.6 % total link strength; Cluster 7 for low-flow anesthesia – 28 papers (3.8 %) with 3.6 % total link strength.Conclusion. Scientometric studies can enhance the data support for scientific research of advanced strategies to optimize human functional status and increasing performance at work for professionals operating in extreme occupational environments.

PROMOÇÃO DA SAÚDE E BEM-ESTAR EM IDOSOS ATRAVÉS DE PROGRAMAS DE EXERCICIOS FUNCIONAL: UMA REVISÃO INTEGRATIVA

This study presents an integrative review on the benefits of functional exercises for elderly health and well-being. With the global aging population and associated public health challenges, it is crucial to explore practices that enhance quality of life (SILVA; SANTOS, 2019). The research analyzed studies that highlight how functional training aids in maintaining physical fitness, autonomy, and disease prevention. Observed benefits include improvements in physical abilities, such as strength and balance, and cognitive function (ALMEIDA; CARDOSO, 2022), as well as a positive impact on social interaction and psychological well-being among the elderly (FREITAS; ALMEIDA, 2021). The study also discusses adapting exercise programs to meet individual needs, considering factors like health conditions and reduced mobility (RODRIGUES; LIMA, 2023)

Feasibility, usability and acceptability of a lifestyle-integrated multicomponent exercise delivered via a mobile health platform in community-dwelling pre-frail older adults: a short-term, mixed-methods, prospective pilot study

BackgroundPre-frailty is a window of opportunity for frailty reversal and can be enhanced by multicomponent exercise. The Lifestyle-integrated Functional Exercise (LiFE) program may be a promising alternative to overcome traditional exercise barriers. The latest advancements in mobile health (mHealth) technology have enabled individuals to retain the advantages of supervised exercise training within group settings while providing exercise programs that can be accessed and completed at home. This study aims to assess the feasibility, acceptability, and primary efficacy of the PF-Life program, which is the Lifestyle-Integrated Functional Exercise program for Pre-Frail supported by an mHealth platform.MethodsSixteen pre-frail adults aged ≥ 65 years were recruited from five community health centers in Fuzhou, China. All participants were prescribed the PF-Life program by geriatricians using the mhealth platform (web-based portal). Participants engaged in the customized exercises program following in-app video instructions and feedback on the mhealth platform (smartphone application). Physical activity (PA) and sedentary behavior (SB) were registered daily through wearable devices. Study endpoints were feasibility (retention rate, compliance rate, adverse events), usability (system usability scale), acceptability (qualitative interviews), changes in physical function (timed up and go (TUG), handgrip strength (HGS), and 30-second chair rise tests), PA and SB.ResultsThe intervention was feasible, 88% of participants adhered completely to the study protocol, and 95% had completed at least 75% of the prescribed experimental duration. System usability was high (85 out of 100 best imaginable). Changes were observed from baseline to follow-up for total HGS (21.41 ± 6.38 vs. 24.12 ± 6.62 kg, P < 0.05, d = 0.714), TUG (8.23 ± 1.33 vs. 7.48 ± 2.01 s, P < 0.01, d = 1.647) and 30-second chair rise test (17.13 ± 4.3 vs. 20.04 ± 4.54 repetitions, P < 0.01, d = 0.94). In addition, SB decreased by a mean of 33 min/day (P < 0.01), and low physical activity increased by 31 min/day (P < 0.01). No adverse events occurred. The majority of participants found the PF-Life program to be straightforward, adaptable, and easily integrable into their daily routines.ConclusionsPreliminary studies have demonstrated that the PF-life program exhibits good compliance, safety, and usability for the pre-frail elderly population. Large-scale randomized controlled trials are required to ascertain its long-term effectiveness.

Impact of various training programs on lower limb biomechanics in adolescent Latin dancers

Latin dance attracts many young dancers globally. While these adolescents exhibit flexibility and imitation skills, their muscular strength and neuromuscular control often fall short, making complex movements challenging. Thus, incorporating functional training methods is essential for enhancing performance and reducing injury risk. This study, a total of 30 adolescent female Latin dancers aged 12–14 years with at least one year of training and competition experience were recruited for this study and randomly divided into two groups: One group of 15 students (average height 154.37 ± 3.82 cm, average weight 45.31 ± 5.29 kg) received traditional Latin dance training, and the other group of 15 students (15 students average height 154.73 ± 4.28 cm, average weight 44.63 ± 4.37 kg) received traditional Latin dance training and based on traditional Latin dance training, functional exercise was carried out for 12 weeks. A Vicon motion capture system, force platform, and electromyography were used to collect biomechanical data. Paired samples t-tests assessed significant differences between groups pre- and post-intervention. The experimental group showed significant improvements post-intervention: in the sagittal plane, ankle joint angles improved by 14.01% to 52.21% (p &lt; 0.001); in the coronal plane, knee joint angles increased by 0% to 31.21% (p &lt; 0.001) and 66.67% to 100% (p &lt; 0.001); in the horizontal plane, hip joint angles improved by 4.99% to 76.00% (p &lt; 0.001). Muscle activation showed significant increases in gastrocnemius lateral (p = 0.016), gluteus maximus (p = 0.001), tibialis anterior (p = 0.014), and rectus femoris (p &lt; 0.001). Functional training enhances joint flexibility, muscle activation, balance, and overall performance in adolescent Latin dancers. Integrating functional training into regular routines can improve athletic performance and lower injury risk, informing the development of targeted training programs.

A Novel Unilateral Bi/Multi-Portal Endoscopic Transforaminal Interbody Fusion Utilizing Uniaxial Spinal Endoscope Instead of Arthroscope: Technical Note and Preliminary Clinical Results.

Currently, traditional UBE surgery, which is based on arthroscope, has been increasingly employed for complex lumbar degenerative diseases. However, this approach is associated with complications such as intraoperative dural sac tears, nerve root injuries, and postoperative epidural hematomas. In response to these challenges, we propose a novel technique utilizing uniaxial spinal endoscope to replace arthroscope-Unilateral Bi/Multi-Portal Endoscopy (UME). This new method has successfully treated complex lumbar disc herniation and spinal stenosis, resulting in improved postoperative outcomes and a reduction in complications. Based on the previous findings, we utilized uniaxial spinal endoscopy as the primary operating method, with the assistance of multi-portal endoscopic techniques (UME-TLIF), to perform transforaminal lumbar interbody fusion. The feasibility and preliminary clinical results have been presented in this paper. A total of 18 patients (8 men and 10 women, aged 52.6 ± 15.29 years) diagnosed with lumbar degenerative diseases, such as giant lumbar disc herniation, severe lumbar spinal stenosis, or lumbar spondylolisthesis, were included in this study from January 2022 to March 2023. Various parameters including operation time, ambulatory time, intraoperative fluoroscopy times, hospitalization days, and complications were recorded during the perioperative period. Clinically relevant symptoms were evaluated and documented 1, 3, 6, and 12 months postoperatively. Visual analogue scale (VAS) scores for lower back pain and leg pain, as well as the Oswestry disability index (ODI), were measured. The extent of lumbar interbody fusion was assessed using lumbar X-ray and CT scans at the 12-months follow-up. MRI was performed to assess the degree of nerve decompression in patients at the same time points. The paired t-test or Wilcoxon signed-rank test were used as statistical methods. The single-segment UME-TLIF procedure had an average operation time of 211 ± 53.3 min, and the average number of X-rays taken during the operation was 11.78 ± 5.32. Patients were able to walk and perform functional exercises approximately 35.11 ± 8.41 h post-surgery, and the average duration of hospital stay was 8.5 ± 2.27 days. The VAS and ODI values at each time point post-surgery were significantly lower than the respective pre-surgery values (p < 0.05). Two patients developed postoperative sensory disturbances which significantly improved with conservative treatment. Furthermore, a follow-up CT scan conducted 12 months post-surgery showed 100% fusion rate of the surgical segments in all patients. UME-TLIF is an endoscopy-assisted fusion procedure that minimizes muscle damage in patients and allows early rehabilitation. This technique broadens the surgical applications of uniaxial spinal endoscope as a surgical tool, particularly benefitingpatients diagnosed with severe lumbar disc herniation and lumbar instability.

The effect of twelve weeks of high-intensity functional training and Ginkgo biloba consumption on the serum levels of some inflammatory cytokines in operational male firefighters of Yazd city

Introduction: functional exercises and consumption of the medicinal plant Ginkgo biloba, a natural source of flavonoids and polyphenolic compounds, have beneficial effects in improving the inflammatory state and physical performance of people exposed to occupational stress. Therefore, the aim of the present study was to investigate the effect of 12 weeks of high-intensity functional training and consumption of Ginkgo biloba extract on the serum levels of interleukin-8 and interleukin-1β in operational male firefighters of Yazd city. Materials and Methods: For this purpose, 48 male firefighters were randomly divided into four groups including high-intensity functional training (HIFT), high-intensity functional training with ginkgo biloba consumption, ginkgo biloba extract consumption, and control-placebo. The training was carried out for 12 weeks and 4 sessions per week. Ginkgo biloba extract (80 mg) was administered as two capsules once a day after breakfast for 12 weeks. Blood samples were taken before and 48 hours after the last training session. Data were analyzed using two-way analysis of variance with SPSS-26 software. Results: The results showed that the interaction effect of exercise and ginkgo biloba extract, as well as the effect of exercise and ginkgo biloba extract alone, caused a significant decrease in the serum levels of interleukin-8 and interleukin-1β (p&lt;0.05). The highest percentage of changes in interleukin-8 and interleukin-1β were obtained following exercise intervention along with the consumption of Ginkgo biloba extract. Conclusion: Performing high-intensity functional exercises with Ginkgo biloba extract had the greatest effect in reducing serum levels of inflammatory indicators and improving oxidative stress conditions in firefighters.

The one-minute sit-to-stand test is an alternative to the 6-minute walk test in patients with atrial fibrillation: A cross-sectional study and ROC curve analysis

BackgroundThe one-minute sit-to-stand test (1STST) is an easy-to-administer, space and time-saving test for determining functional exercise capacity in cardiac disease. This study aimed to investigate the 1STSt-test-retest reliability and convergent validity and compare its physiological responses to the six-minute walk test (6MWT) in patients with Atrial fibrillation (AF). MethodsForty-five patients with AF were included in this study. Functional exercise capacity was evaluated using the 1STST and 6MWT. For assessing test-retest reliability, the intraclass correlation coefficient and Bland-Altman plots were utilised. Convergent validity was determined by correlation analysis 1 STST and 6MWT, age, European Heart Rhythm Association score, ejection fraction, and quality of life. The cut-off point of 1STST was defined using ROC analysis. ResultsWith an intraclass correlation coefficient value of 0.975 [95 % confidence interval (CI) 0.954–0.986], the 1STST demonstrated excellent-test-retest reliability. Physiological responses after tests were similar in the 1STST and 6MWT (p > 0.05). The number of 1STST repetitions was strongly associated with 6MWT distance (r = 0.809; p < 0.001). A cut-off value of ≤13 repetitions in the number of 1STST repetitions was defined as functional impairment related to an increased risk of clinical events [sensitivity: 100 %, specificity: 84.6 %; AUC:0.94; 95 % CI 0.82 to 0.98; p < 0.001]. ConclusionsThe 1STST is a reliable and valid assessment tool that produced comparable hemodynamic responses to the 6MWT in patients with AF. Considering its feasibility and time efficiency, healthcare professionals can use the 1STST rather than the 6MWT test to measure functional exercise status in a constrained environment for this patient group.

Total knee arthroplasty combined with simultaneous open reduction and internal fixation in the treatment of knee osteoarthritis with patellar fracture: a case report and review of the literature

BackgroundPatients with severe knee osteoarthritis combined with patellar fracture are rare, and it is unclear whether single-stage surgery affects the enhanced recovery after surgery.Case presentationThis case report describes two patients of Han nationality. A 69-year-old male patient was previously diagnosed with severe knee osteoarthritis of the left knee joint and was treated conservatively with long-term oral nonsteroidal antiinflammatory drugs and intraarticular injection of sodium hyaluronate. He was hospitalized for acute left knee injury owing to a fall from a height. He was diagnosed with knee osteoarthritis of the left knee joint and patellar fracture. Another 74-year-old female patient was previously diagnosed with severe knee osteoarthritis, long-term oral nonsteroidal antiinflammatory drugs and topical Chinese medicine to relieve the pain. A month ago, she fell down the stairs and fractured the patella in her left knee, she was diagnosed with severe left knee osteoarthritis combined with an old left patella fracture. Both patients were successfully treated by single-stage primary total knee arthroplasty and fixation of the patellar fracture. They both carried out early functional exercise normally and successfully achieved enhanced recovery.ConclusionSuccessful single stage total knee replacement with patella management can not only reduce the number of operations, but also enable patients to achieve rapid postoperative recovery. However, single stage may increase the risk of local surgical complications. Therefore, for most patients, especially those with low risk of anesthesia related complications, standard of treatment remains first fixing the patellar fracture and when the fracture is healed proceed with the total knee arthroplasty.

Long-term course and factors influencing work ability and return to work in post-COVID patients 12 months after inpatient rehabilitation

BackgroundRehabilitation plays a crucial role in restoring work ability and facilitating the reintegration of post-COVID patients into the workforce. The impact of rehabilitation on work ability and return to work (RTW) of post-COVID patients remains poorly understood. This study was conducted to assess the work ability and RTW of post-COVID patients before rehabilitation and 12 months after rehabilitation and to identify physical and neuropsychological health factors influencing RTW 12 months after rehabilitation.MethodsThis longitudinal observational study included 114 post-COVID patients with work-related SARS-CoV-2 infection who underwent inpatient post-COVID rehabilitation with indicative focus on pulmonology and/or psychotraumatology (interval between date of SARS-CoV-2 infection and start of rehabilitation: M = 412.90 days). Employment status, work ability, and the subjective prognosis of employment (SPE) scale were assessed before rehabilitation (T1) and 12 months after rehabilitation (T4). The predictors analysed at T4 were functional exercise capacity, physical activity, subjective physical and mental health status, fatigue, depression, and cognitive function. Longitudinal analyses were performed via the Wilcoxon signed-rank test. Logistic and linear regression analyses identified predictors of work ability and return to work (RTW), whereas mediation analyses examined the relationships between these predictors and work ability.ResultsAt T4, the median of WAI total score indicated poor work ability, which significantly worsened over time (p < 0.001; r = 0.484). The SPE scale significantly increased from T1 to T4 (p = 0.022, r = -0.216). A total of 48.6% of patients had returned to work 12 months after rehabilitation. Fatigue was identified as the main predictor of reduced work ability and RTW, with each unit increase in fatigue severity decreasing the odds of RTW by 3.1%. In addition, physical capacity and subjective health status were significant predictors of perceived work ability.ConclusionsThe findings highlight the significant challenges that post-COVID patients face in regaining work ability and achieving successful RTW 12 months after rehabilitation. Fatigue appears to be an important predictor of work ability and RTW. To optimize recovery and enhance both biopsychosocial health and work ability, it is crucial to develop and implement personalised interventions that address fatigue, improve physical capacity, and support mental health.Trial registrationThis study is registered in the German Clinical Trials Register under DRKS00022928.

The Effects of Health Education Model Based on Goal-setting Theory on lifestyle, Diet and Nutrition, and Psychological Regulation of Thyroid Cancer Patients after Surgery

Objective: The effects of a health education model based on goal-setting theory on lifestyle, diet and nutrition, and psychological regulation of thyroid cancer patients after surgery. Methods: A total of 60 thyroid cancer patients from the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine from January 1, 2020 ~ December 31, 2023 were selected and grouped.They were divided into 30 observation groups and 30 control groups based on the principle that baseline data between groups could be compared. Patients in both groups were given routine postoperative care for thyroid cancer, and on this basis, the control group was given routine health education intervention, and the observation group was given health education intervention based on goal-setting theory. Both groups were intervened until discharge, and both groups were followed up for 1 month after discharge. Before the intervention and one week after the intervention, the self-made disease knowledge questionnaire and the self-management assessment scale of cancer patients were used to evaluate the disease knowledge, self-management ability and quality of life of the two groups. The compliance of patients with rehabilitation exercises, hoarseness, tetany and quality of life before intervention and at the end of follow-up were observed. Results: After 1 month of intervention, there were significant differences between the observation group and the normal control group in terms of disease knowledge knowledge score, self-efficacy, control of daily living habits, treatment of disease symptoms, and management of psychological adjustment (P&lt;0.05). In the process of intervention, the compliance of the observation group was significantly higher than that of the control group, and there was a significant difference, (P&lt;0.05). At the end of the follow-up, the symptoms of hoarseness, tetany and dyspnea in the observation group were significantly lower than those in the control group, and the difference was statistically significant (P&lt;0.05). Finally, the two groups were significantly better than the control group in terms of physiological, psychological, functional exercise and special scores (P&lt;0.05). Conclusion: Health education based on goal-setting theory has high application value in thyroid cancer surgery patients, which can improve patients' awareness of the disease, improve patients' rehabilitation compliance and self-management ability, and promote the recovery and improvement of postoperative living standards.

Optimizing a resistance training program to increase muscle strength: a comprehensive planning approach - a systematic review

Background: Muscle strength is an essential factor in maintaining one's health and quality of life. Resistance training programs have been known to be effective in improving muscle strength. However, their success can be affected by various factors, including exercise variety, volume, intensity, frequency, and duration. To optimize the effects of a resistance training program, a comprehensive planning approach is essential. Study Objective: This study aimed to conduct a systematic review of the literature to explore a comprehensive planning approach in optimizing resistance exercise programs to improve muscle strength. Materials and Methods: A systematic method was used to identify relevant studies from various scientific databases. Inclusion and exclusion criteria were established to select studies that fit the research objectives. Data from the selected studies were extracted and analyzed to evaluate the effectiveness and planning approaches used in resistance exercise programs. Results: The results of this systematic review indicate that a comprehensive planning approach, including individualization of the program, progressive and adaptive, integration of functional exercises, and periodic monitoring and evaluation, are critical factors in optimizing resistance exercise programs. Studies showed differences in the effectiveness of resistance training programs based on these factors. Conclusion: By integrating a comprehensive planning approach, resistance exercise programs can be optimized to achieve maximal muscle strength gains. Practical implications of these findings include relevance to specific populations and application in the context of rehabilitation. Future research should focus more on understanding the interactions between these factors and explore more specific planning approaches to improve the effectiveness of resistance training programs.

Efficacy of specific drug class therapy in pulmonary arterial hypertension associated with HIV, portal hypertension or both: a single Center experience

Abstract Background Pulmonary arterial hypertension (PAH) is a rare complication of both HIV infection (HIV-PAH) and portal hypertension (Po-PAH); it can occur in patients with both diseases (HIV/Po-PAH). The use of the PAH-specific drug classes (prostanoids, endothelin-1 receptor antagonists [ERA] and phosphodiesterase-5 inhibitors [PDE5-i]) is largely justified by retrospective and observational case reports since, to date, there are no randomized clinical trials except for the PORTICO trial which demonstrated the efficacy of macitentan in Po-PAH. Purpose the aim of the study was to evaluate the efficacy of PAH-specific drugs, both monotherapy and dual oral upfront therapy (ERA + PDE5i started within 1 month apart), in patients with Po-PAH, HIV/Po-PAH and HIV-PAH. Methods Between 1998 and 2023 we enrolled patients with Po-PAH, HIV-PAH and HIV/Po-PAH referred to our Center and undergoing monotherapy with prostanoid, ERA and PDE5-I or dual upfront oral therapy. The efficacy of the drugs was assessed by comparing clinical parameters (NYHA functional class), exercise capacity (six-minute walking test) and hemodynamic parameters at baseline and after a treatment period of 3-6 months. The data are expressed as mean and standard deviation and were compared with Student's t-test for paired data. Results 128 patients were enrolled (83 Po-PAH, 23 HIV/Po-PAH and 22 HIV-PAH). 20 were treated with ERA monotherapy, 90 with PDE5-I, 13 with prostanoids and 5 treated with dual oral upfront therapy. Conclusions Prostanoids, ERAs and PDE5-Is, both in monotherapy and as dual upfront oral therapy, are associated with a significant improvement in functional class, exercise capacity and hemodynamic parameters. The effect of such drugs is similar to patients suffering from other forms of PAH.

Moderate intensity exercise training ameliorates the heart failure with preserved ejection fraction phenotype in a preclinical model by improving cardiometabolic fitness

Abstract Introduction and Aim Exercise intolerance is a hallmark feature of patients with heart failure with preserved ejection fraction (HFpEF).While clinical evidence suggests potential benefits of exercise training in HFpEF, its mechanisms remain largely unknown.In this study, we used a translationally relevant murine model of cardiometabolic HFpEF(1) to assess whether moderate intensity continuous training(MICT) can ameliorate the HFpEF phenotype in mice and promote cardiometabolic health. Methods Twenty-five adult, male C57BL/6N were fed with the combination of high fat diet(HFD;D12492,Research diet)and L-NAME(0.5 g/L,in drinking water) for 15 weeks to elicit HFpEF as previously described(1).After the establishment of the HFpEF phenotype, mice were randomized in two groups:sedentary(SED,n= 10) and exercised(MICT,n=15)mice.MICT was carried out according to the protocol:running on 10-degree positive inclination treadmill for 8 consecutive weeks,5 times/week,60 minutes/day,at a speed gradually increasing from 0.1 to 0.2 m/sec on a weekly basis.Morphometry, echocardiography(TTE),isoproterenol-induced stress echocardiography(SE),time domain nuclear magnetic resonance, and treadmill exhaustion tests were performed at the beginning and end of MICT.Additionally, at the end of MICT blood and tissues were collected for proteomics analysis(Fig1).Non-trained male C57BL/6N mice(37w) were used as controls for the HFpEF mice. Results Before randomization, all HFpEF mice were similar in terms of phenotypic characteristics. Compared to SED mice, MICT induced a significantly decrease in body weight driven by a reduction of total fat mass with an increased in lean mass(Fig2A+B).Interestingly, MICT had no impact on skeletal muscle mass for all different muscle groups evaluated (extensor digitorum longus, soleus and tibialis anterior).Importantly, MICT led to a significant improvement in exercise capacity in HFpEF mice, as shown by increased running distance and time, surpassing even the running distance seen in non-HFpEF mice (SED:62.8±18.7,MICT:305.7±13.9,non-HFpEF mice: 129.72±15.2meters,p&amp;lt;0.001).Preclinical surrogate of HFpEF such as pulmonary congestion, evaluated by index lung weights, improved after aerobic training.Following MICT there was a marked improvement in diastolic dysfunction(measured by E/E’ratio) both at rest(SED:36.5±3.3,MICT:23.3±5.09,p&amp;lt;0.001) and after isoproterenol challenge(SED:42.6±15.1,MICT:26.09±3.75,p&amp;lt;0.001)(Fig2C).Moreover, the wet cardiac mass was lower in the MICT group(Fig2A), suggesting potential amelioration in cardiac hypertrophy following aerobic training. Conclusion Eight weeks of supervised MICT on treadmill improves functional status, exercise capacity, and diastolic function in a cardiometabolic HFpEF murine model.The most significant effects were seen on weight loss and fat mass reduction.Our findings suggest a beneficial impact of aerobic exercise in mitigating HFpEF by improving metabolic fitness in the preclinical HFpEF model.Fig1-Study DesignFig2-Characteristics SED vs MICT groups

Improving exercise cardiac reserve assessment using a novel cardiopulmonary and echocardiography testing protocol (CPET-ESE) based on individualised exercise intensity domains

Abstract Background Functional exercise stress echocardiography (ESE) is used to quantify changes in cardiac reserve and can improve early cardiac dysfunction diagnosis and follow-up.[1.2] Current ESE protocols do not account for individual variations in fitness and heart rate response, leading to difficulties in defining normal reference values.[2,3] Physiologically defined exercise intensity domains could be implemented as part of combined cardiopulmonary and ESE testing (CPET-ESE) to address this problem. Purpose We propose that using exercise intensity domains as part of CPET-ESE will result in cardiac reserve values not influenced by individual cardiorespiratory fitness or physical activity (PA) levels. We also hypothesise by matching work-rates and heart rates (HR), respectively, cardiac reserve will be higher in those exercising at the higher exercise intensity domain. Methods A total of 45 healthy adults (mean age 43.8 ± 14.2, range 18-65 y) underwent a CPET followed by a CPET-ESE consisting of two 6-minute stages: 1. Moderate intensity (MOD) at 90% of the work-rate at the gas exchange threshold (GET) and 2. High intensity (HIGH) at 40% of the difference between GET and peak. Global left ventricular and right ventricular free wall (LV and RV) longitudinal strain (Sl), RV fractional area change (RV-FAC), peak LV and RV TDI derived systolic (S’) and diastolic velocities (E’) were measured at each step, including rest. HIGH steps were matched 1-to-n with MOD steps from other participants based on work-rate and HR, respectively. Questionnaire derived PA was classified as low, moderate, and high active. Cardiorespiratory fitness was measured as peak oxygen uptake relative to body mass (mL·kg-1·min-1). Results After adjusting for age and sex, neither higher PA nor peak VO2 were associated with higher cardiac function parameters at either intensity (Table 1). Higher peak VO2 was associated with higher work-rate for HIGH only, while higher PA was associated with lower HR for MOD only (interaction term p&amp;lt;0.05). When paired by matching HR and work-rate, respectively, HIGH was associated with higher cardiac function parameters compared to MOD (all except for LV-S’ and RV-FAC when HR matched, Table 2), despite those matched from HIGH being older, less physically active and having lower peak VO2 (p&amp;lt;0.05 for all). Conclusions Current ESE protocols, which define submaximal exercise intensity using arbitrary work-rate or HR targets,[3] do not account for the complex differences in exercise response between healthy individuals. Cardiac function augmentation during exercise is likely a response to VO2 kinetics and this is not accurately described by either HR or work-rate alone. We derived normal reference values for cardiac reserve from implementing physiologically defined exercise intensity domains within the combined CPET-ESE testing frameworks. These values could be more appropriately used when comparing diverse clinical populations using CPET-ESE.

The effect of functional exercise program on physical functioning in older adults aged 60 years or more: A systematic review and meta-analysis of randomized controlled trials

ObjectiveIn this systematic review and meta-analysis, we assessed the impact of functional exercise training on physical functioning parameters in older adults 60 years and older. MethodDatabases including PubMed, MEDLINE, CINAHL, SPORTDiscus, and Cochrane Library were systematically searched. ResultsSixteen articles were included. Meta-analysis demonstrated that functional training significantly improved Barthel index (p = 0.01), gait speed (p = 0.002), gait cadence (p = 0.0002), Berg Balance Scale (p = 0.0003), Timed Up and Go test (TUG; p = 0.02), step length (p < 0.0001), Five Chair Stand (p < 0.0001) and physical activity questionnaire for the older adults score (p < 0.00001). However, hand grip strength remained unchanged. DiscussionThese findings underscore the significance of incorporating functional exercises in interventions for healthy aging and maintaining independence among older individuals. Further investigation is needed to explore long-term effects and optimal implementation strategies for functional exercise regimens in this populations.

Treatment of proximal phalangeal fracture with miniature combined external fixator

To investigate the clinical effect of limited open reduction treatment of proximal phalangeal fracture with miniature external fixator combined with small incision. Between January 2020 and December 2022, 29 patients with proximal phalangeal fracture were treated with micro external fixator combined with small incision in fracture plane, including 23 males and 6 females, aged from 19 to 62 years old with an average of (36.2±21.0) years old. Five patients with open phalangeal fracture were treated with stageⅠsurgery, 24 cases of closed phalangeal fracture were treated with elective surgery. At the 6 month follow-up, the curative effect was evaluated according to the total active flexion scale (TAFS) of the American Hand Surgery Association. The fracture healing, nail path, local soft tissue healing, and complications were observed. All the 29 patients were followed up for 6 to 10 months with an average of(8.3±2.1) months, 3 patients had delayed fracture healing, 1 patient had distal skin numbness, symptoms were relieved after nutritional nerve treatment, no external fixator broken nails, no infection, the nail path and small incision healing was good, bone healing was achieved at the end of follow-up. Fracture healing time ranged from 10 to 24 with an average of (13.7±3.1) weeks. Six months after operation, according to the TAFS standard, 19 cases (227.68±4.23) were excellent, 7 cases (203.86±14.32) were good, and 3 cases (170.33±7.32) were poor. The micro-combined external fixator combined with limited incision with small incision can be used in the treatment of proximal phalangeal fracture.

A functional exercise program improves pain and health related quality of life in patients with fibromyalgia: a randomized controlled trial

Background/objectiveFibromyalgia is a non-inflammatory syndrome characterized by generalized muscle pain, with other symptoms. Numerous forms of physical training for this population have been studied through high-quality randomized clinical trials involving strength, flexibility, aerobic conditioning and multicomponent exercise interventions. This research evaluated the effectiveness of a functional exercise program at reducing pain, improving functional capacity, increasing muscle strength as well as improving flexibility, balance and quality of life in individuals with fibromyalgia.MethodsEighty-two women with fibromyalgia were randomized into two groups. The functional exercise group performed functional exercises in 45-minute sessions twice per week for 14 weeks. The stretching exercise group performed flexibility exercises with the same duration and frequency. Outcome measures were: visual analog scale for widespread pain; Fibromyalgia Impact Questionnaire for health-related quality of life; Timed Up and Go test for functional performance; one-repetition maximum for muscle strength, Sit and Reach test on Wells bench for flexibility; Berg Balance Scale for balance; SF-36 for general quality of life.ResultsAfter the intervention, the functional exercise group had a statistically significant reduction in pain (interaction p = 0.002), and improvement in health-related quality of life measured by the Fibromyalgia Impact Questionnaire (interaction p < 0.001) and in general health state domain of SF-36 (interaction p = 0.043) compared to the stretching exercise group. No significant differences between groups were found regarding improvements in functional capacity, muscle strength, flexibility or balance.ConclusionFunctional exercise training was effective at reducing pain and improving quality of life in patients with fibromyalgia compared to stretching exercises.Trial registrationClinicalTrials.gov Identifier: NCT03682588 First prospectively registered in March 2018.

Improved functional oral intake and exercise training attenuate decline in aerobic capacity following chemoradiotherapy in patients with esophageal cancer.

To investigate the impact of chemoradiotherapy on the physical fitness of patients with oesophageal cancer, and the clinical factors influencing it. A total of 67 participants successfully completed the study, with 18 of them engaging in supervised, in-hospital aerobic training at moderate intensity for a minimum of 20 sessions. Cardiopulmonary exercise testing, hand grip strength, body composition assessed via bioelectrical impedance analysis, patient-generated subjective global assessment, albumin, and the Functional Oral Intake Scale (FOIS) were evaluated before chemoradiotherapy and 6-8 weeks after its completion. Among the participants, cardiopulmonary fitness, hand grip strength, and phase angle of BC-BIA declined during chemoradiotherapy. Before and after chemoradiotherapy, V̇O2peak was 19.6 ± 4.4 and 17.4 ± 3.9 mL/min/kg respectively. The improvement in FOIS during chemoradiotherapy showed a positive correlation with changes in aerobic capacity. Additionally, exercise training was associated with attenuating the decline in aerobic capacity. Physical fitness deteriorated in patients with oesophageal cancer following chemoradiotherapy. Improvement in dysphagia helps maintain aerobic capacity. Additionally, exercise training has the potential to mitigate the decline. This discovery can serve as a reference for enhancing holistic care for patients with oesophageal cancer.

A clinical study on the effect of axillary approach in the treatment of Ideberg type II scapular glenoid fractures

BackgroundDue to its deep position and complex surrounding anatomy, the scapular glenoid fracture was relatively difficult to deal with especially in cases of severe fracture displacement. Improper treatment may lead to failure of internal fixation and poor fracture reduction, severely affecting the function of the shoulder joint. Inferior scapular glenoid fracture was Ideberg type II fracture, and posterior approach was commonly used to deal with inferior scapular glenoid fracture. However, there are shortcomings of above surgical approach for inferior scapular glenoid fracture, such as insufficient exposure of the operative field, significant trauma, and limited screw fixation direction. This study adopts the axillary approach for surgery, which has certain advantages.MethodsThe clinical data of 13 patients with Ideberg type II scapular glenoid fractures treated from December 2018 to January 2024 were retrospectively analyzed. There were 8 males and 5 females, with an age range of 19 to 58 years and an average age of 38 years. The causes of injury were falls from heights in 7 cases and car accidents in 6 cases. There were 5 cases on the left side and 8 cases on the right side. The time from injury to surgery was 2 to 11 days, with an average of 5.5 days. All cases underwent open reduction and internal fixation through the axillary approach. Postoperative X-ray and CT three-dimensional reconstruction were performed on the next day to evaluate the fracture reduction and the position of internal fixation. During the follow-up period, follow-up examinations were performed every two months in the first half of the year and every three months in the second half. CT scans were performed during the examinations to assess the glenohumeral joint congruence, fracture healing, and position of internal fixation. The shoulder joint function was evaluated at 6 months postoperatively according to the Constant-Murley value score.ResultsThe patients all achieved primary wound healing after surgery, without any complications such as infection or nerve injury. Re-examination on the second day after operation, all fractures obtained excellent reduction, and the internal fixation was in excellent position, and no screw was found to enter the joint cavity. All patients in this group were followed up for 6 to 25 months, with an average follow-up time of 11.7 months. All fractures were bony unioned, and the healing time ranged from 4 to 6 months, with an average healing time of 4.8 months. At 6-month follow-up, according to the Constant-Murley score, 11 cases were excellent and 2 case was good.ConclusionOpen reduction and internal fixation through the axillary approach is an feasible and safe surgical method for the treatment in scapular Ideberg type II glenoid fractures with less stripping of soft tissue, minimal surgical trauma, and the incision is concealed and beautiful. It can provide a strong internal fixation for fractures, so patients can perform functional exercise early after operation, and the clinical results is satisfactory.

A Study on the Development of Information and Communication Technology-Based Oral Functional Rehabilitation Exercise Program Content for Elderly People.

Background/Objectives: This study was conducted to develop information and communication technology (ICT)-based oral functional rehabilitation exercise (OFRE) program content to effectively improve the oral function of the elderly people. Methods: After selecting evidence-based effective OFRE items through systematic review, the final items were constructed through the validity evaluation of detailed items through an expert Delphi survey. The items were composed in a simple content form that can be performed directly and applied to ICT-based mobile applications. Results: The final content items consisted of an oral functional motor-ability measurement, oral Pilates videos, and games. The first is to measure the maximum opening amount before and after exercise, and the opening amount was designed to be measured by eating the fruit displayed on the screen by opening and closing the lips. The second one consisted of eight exercises in the video, and each exercise was to be performed at least three times a day, with a total of two sets. The third is a salivary secretion function exercise that stimulates the salivary glands to stimulate the user's interest and enable them to perform oral movements on their own. It consists of a lip and respiratory muscle exercise that inflates the cheeks and bursts a balloon, and the image disappears when the word in the image presented on the screen is pronounced correctly. It consists of pronunciation exercises. Conclusions: This content development attempt can be expanded into new convergence research linked to ICT and can be used as basic data when developing related content as part of digital care for the elderly in the future.
