Distribution of lipid droplets in hippocampal neurons and microglia: impact of diabetes and exercise.

Neuroinflammation, aging, and neurodegenerative disorders are associated with excessive accumulation of neutral lipids in lipid droplets (LDs) in microglia. Type 2 diabetes mellitus (T2DM) may cause neuroinflammation and is a risk factor for neurodegenerative disorders. Here, we show that hippocampal pyramidal neurons contain smaller, more abundant LDs than their neighboring microglia. The density of LDs varied between pyramidal cells in adjacent subregions, with CA3 neurons containing more LDs than CA1 neurons. Within the CA3 region, a gradual increase in the LD content along the pyramidal layer from the hilus toward CA2 was observed. Interestingly, the high neuronal LD content correlated with less ramified microglial morphotypes. Using the db/db model of T2DM, we demonstrated that diabetes increased the number of LDs per microglial cell without affecting the neuronal LD density. High-intensity interval exercise induced smaller changes in the number of LDs in microglia but was not sufficient to counteract the diabetes-induced changes in LD accumulation. The changes observed in response to T2DM may contribute to the cerebral effects of T2DM and provide a mechanistic link between T2DM and neurodegenerative disorders.

Delaying post-exercise carbohydrate intake impairs next-day exercise capacity but not muscle glycogen or molecular responses.

To investigate how delayed post-exercise carbohydrate intake affects muscle glycogen, metabolic- and mitochondrial-related molecular responses, and subsequent high-intensity interval exercise (HIIE) capacity. In a double-blind cross-over design, nine recreationally active men performed HIIE (10 × 2-min cycling, ~94% W˙peak) in the fed state, on two occasions. During 0-3 h post-HIIE, participants drank either carbohydrates ("Immediate Carbohydrate" [IC], providing 2.4 g/kg) or water ("Delayed Carbohydrate" [DC]); total carbohydrate intake over 24 h post-HIIE was matched (~7 g/kg/d). Skeletal muscle (sampled pre-HIIE, post-HIIE, +3 h, +8 h, +24 h) was analyzed for whole-muscle glycogen and mRNA content, plus signaling proteins in cytoplasmic- and nuclear-enriched fractions. After 24 h, participants repeated the HIIE protocol until failure, to test subsequent HIIE capacity; blood lactate, heart rate, and ratings of perceived effort (RPE) were measured throughout. Muscle glycogen concentrations, and relative changes, were similar between conditions throughout (p > 0.05). Muscle glycogen was reduced from baseline (mean ± SD mmol/kg dm; IC: 409 ± 166; DC: 352 ± 76) at post-HIIE (IC: 253 ± 96; DC: 214 ± 82), +3 h (IC: 276 ± 62; DC: 269 ± 116) and + 8 h (IC: 321 ± 56; DC: 269 ± 116), returning to near-baseline by +24 h. Several genes (PGC-1ɑ, p53) and proteins (p-ACCSer79, p-P38 MAPKThr180/Tyr182) elicited typical exercise-induced changes irrespective of condition. Delaying carbohydrate intake reduced next-day HIIE capacity (5 ± 3 intervals) and increased RPE (~2 ratings), despite similar physiological responses between conditions. Molecular responses to HIIE (performed in the fed state) were not enhanced by delayed post-exercise carbohydrate intake. Our findings support immediate post-exercise refueling if the goal is to maximize next-day HIIE capacity and recovery time is ≤24 h.

Evaluation of the single and combined therapeutic effects of individually manufactured earplug therapy in patients with myogenous temporomandibular disorders: A randomized controlled clinical trial

ObjectiveTo evaluate the effect of individually manufactured earplug therapy on pain intensity (PI), symptom severity (SS), and maximum mouth opening (MMO), in patients with myogenous temporomandibular disorders (TMD).MethodsOne-hundred-twenty patients were randomly allocated to six groups: Groups EP (earplug), OS (occlusal splint), EX (exercise), EPO (earplug with occlusal splint), EPE (earplug with exercise), and C (control). Outcomes were PI (assessed with a visual analog scale (VAS)), SS (assessed with the modified Symptom Severity Index Questionnaire (mSSI)), and MMO (evaluated with a digital caliper). Measurements were performed at T0 (before the therapy), T1 (1-month follow-up), and T2 (3-month follow-up). Data were analyzed using one-way analysis of variance (ANOVA), Tukey’s HSD, and chi-square tests (alpha = 0.05).ResultsAt T1 and T2, the greatest VAS and mSSI reduction was detected for the groups EPE (VAS = 5.3 ± 1.05, 3.3 ± 0.7; mSSI = 38.2 ± 2.27, 43.6 ± 3.94) and EPO (VAS = 5.2 ± 0.91, 3.2 ± 0.78; mSSI = 36.3 ± 3.97, 42.2 ± 3.19), respectively (p < 0.05). At T1, occlusal splint groups (groups OS (34.8 ± 2.97 mm) and EPO (33.8 ± 3.49 mm)) gave the highest MMO values, while T2 values did not constitute a significant difference with T1 (p > 0.05).ConclusionsThe short-term use of combined earplug therapy resulted in a decrease in both PI and SS. Improvement in MMO in participants using occlusal splints was observed in the 1st month and was maintained through the 3rd month.Clinical RelevanceEarplug therapy can be applied as a complementary therapy to occlusal splint and exercise treatments to decrease PI and SS in patients with myogenous TMD. To achieve functional recovery such as MMO, its combined use with splints should be taken into consideration by clinicians.

Investigating the effect of aerobic exercise on the neuropathy symptoms caused by chemotherapy

Introduction: Currently, there is no effective method to prevent CIPN; and if aerobic exercise combined with drug treatment is more effective than drug treatment alone, the side effects of the drug can be prevented to an acceptable extent by reducing the dose of the relevant drug. Therefore, in the following study, we tried to investigate and compare the effectiveness of two methods of aerobic exercise and drug treatment on the improvement of neuropathy symptoms caused by chemotherapy. Research materials and methods: In this clinical trial study, the first group of patients received duloxetine (Luxta, Obidi company) at a dose of 30 mg for 6 weeks. The second group received duloxetine at a dose of 30 mg along with aerobic exercise for 6 weeks. At the end of the intervention period, all patients were re-evaluated with EMGMCV of both lower limbs. The study data was analyzed using SPSS version 24 software. Findings: Two groups of cases (50 people) with an average age of 55.56 ± 4.21 years and controls (50 people) with an average age of 53.76 ± 4.57 years participated in this study. The results of EMGMCV improved significantly in both groups after the intervention, but the two groups did not show a statistically significant difference after the intervention (P&lt;0.05). Conclusion: Based on the results of the studies and considering that aerobic exercise therapy is simple and available, since there has been no study related to the determination of the effect of combined aerobic exercise that can determine the best and most effective exercise volume affecting neuropathy. And since the existing researches are mostly focused on the effects of exercise on improving performance and neuro-muscular indicators, more clinical studies are needed in this field.

Exploring the feasibility, acceptability, and safety of a real-time cardiac telerehabilitation and tele coaching programme using wearable devices in people with a recent myocardial infarction.

Cardiac rehabilitation (CR) constitutes the recommended nonpharmacological approach for cardiac patients with cardiovascular disease such as people following a recent (i.e., < 4 week) myocardial infarction (MI). Recent evidence suggests that cardiac telerehabilitation may be as effective as traditional (i.e., in person) CR in people following a recent MI. Nevertheless, the feasibility, acceptability, and safety of such an exercise programme has yet to be examined. Forty-four (11 women, 33 men) people following a recent MI were randomly allocated into two groups (online home-based and gym-based groups). The groups underwent a 24-week CR programme thrice per week. All patients performed the baseline, and 24 weeks follow up measurements where feasibility, acceptability, and safety were assessed. Eligibility and recruitment rates were found to be 61.5% and 42%, respectively. Compliance to the thrice weekly, 24-week exercise programme for the online- and gym-based groups were 91.6% and 90.9%, respectively. There were no dropouts during the exercise programmes, however four participants, two from each group, were lost to follow up at 6 months. The average percentage of peak HR (% HRpeak) for the online group was 66.6% ± 4.5 and for the gym-based group was 67.2% ± 5. The average RPE and affect during exercise was for both groups 12 ± 1 ("somewhat hard") and 3 ± 1 ("good"), respectively. During the 6-month exercise intervention period for both groups, the exercise-induced symptoms were minimal to none. The user suitability evaluation questionnaire revealed that the online real time telerehabilitation and tele coaching programme was enjoyable (4.85 ± 0.37) and did not induce general discomfort (1.20 ± 0.41). Our cardiac telerehabilitation programme seems to be feasible, acceptable, safe, and enjoyable for people with a recent MI. Our participants had an overall positive experience and acceptability of the cardiac telerehabilitation and tele coaching using wearable devices.

Pre-exercise supplementation with curcuma xanthorrhiza roxb has minimal impact on red blood cell parameters but reduces oxidative stress: a preliminary study in rats.

This study examined the effects of longterm pre-exercise Curcuma xanthorriza Roxb supplementation on red blood cell indices along with circulating malondialdehyde (MDA) and superoxide dismutase (SOD) levels in response to endurance exercise to address previously inconsistent findings. Male Wistar rats (Rattus norvegicus; n = 20, aged 12-16 weeks) were divided equally into an exercise-only group (C) and three groups supplemented with Curcuma extract at dosages of 6.75 (T1), 13.50 (T2), and 20.25 mg (T3). Curcuma extract supplementation was administered for 28 d immediately prior to exercise. Following 28 d of exhaustive swimming, the hematocrit and erythrocyte count increased by 15% (p = 0.06). Pre-exercise Curcuma supplementation did not significantly affect mean corpuscular volume or mean corpuscular hemoglobin concentration. Longterm exercise intervention resulted in elevated MDA levels by 41% (p <0.001), while Curcuma supplementation (13.50 mg) attenuated this increase by 16.6% (p = 0.09). Additionally, Curcuma supplementation resulted in a dose-dependent increase in SOD levels, with an 82.6% increase observed at 20.25 mg (p = 0.028). Our preliminary findings indicated that pre-exercise supplementation with Curcuma extract had a negligible effect on changes in red blood cell markers, but it mitigated the increase in oxidative stress induced by exercise training. Our future research direction will involve applying the findings to humans.

Impact of an exercise program combined with dietary advice on avoiding insulin prescription in women with gestational diabetes: a randomized controlled trial

ObjectiveTo assess the effectiveness of an exercise intervention, in addition to standard care, in preventing or delaying insulin prescription in women with gestational diabetes mellitus (GDM).DesignRandomised controlled trial.SettingUniversity hospital.PopulationPregnant women at 25–35 weeks of gestation diagnosed with GDM.MethodsWomen in the intervention group participated in weekly, supervised, 30–45 min exercise sessions and were encouraged to accumulate more than 5000 steps per day, tracked by a pedometer, in addition to receiving usual care. The control group received standard care only.Main outcome measureInsulin prescription.ResultsFrom February 2008 through April 2013, 109 women were randomized into the intervention group (n = 57) or the usual care group (n = 52). Two women in the intervention group were excluded from the analysis (one was randomised in error and one was lost to follow-up). Six women never attended the exercise sessions, and two attended fewer than two sessions. However, two-third of women were considered as compliant to the intervention (attended more than 50% of sessions and/or averaged more than 5000 steps/day). The incidence of insulin prescription did not differ between the groups: 31 women (56%) in the intervention group versus 24 women (46%) in the control group (RR 1.22, 95% CI 0.84 to 1.78). The median time from randomization to insulin prescription was also similar between groups (14 days in the intervention group and 13 days in the control group).ConclusionThis study did not demonstrate that an exercise program reduces or delays insulin prescription in women with GDM. Low adherence to the intervention, a small sample size, and the short duration of the program may explain the lack of observed benefit.RegisteredAt clinicaltrials.gov, NCT03174340, 02/06/2017

Analysis of the Effect of Hypertension Gymnastics on Lowering Blood Pressure in Hypertension Patients in the Tapunggaya Health Center Work Area

Introduction: WHO states that hypertension has attacked 22% of the world's population. While the number of hypertension in Southeast Sulawesi itself reached 26.53% or 314,454. One of the non-pharmacological treatments for hypertension is hypertension exercise and the DASH Diet (Dietary Approaches to Stop Hypertension) is a diet pattern aimed at lowering blood pressure by limiting salt intake, saturated fat, and increasing food intake that contains a lot of potassium, calcium, magnesium and high-fiber foods. This study is to analyze the Effect of Hypertension Exercise on Lowering Blood Pressure in Hypertension Patients in the Tapunggaya Health Center Work Area. Method: This type of research is quantitative with an experimental approach with a pretest-posttest design. The research sample was 284 people using a simple random sampling technique. The data collection tool used a blood measurement observation sheet. The statistical test used was the Paired Sample T-Test. Result: Obtained Results before hypertension exercise treatment on decreasing systolic blood pressure average 148 after treatment average blood pressure 134 mmHg. And the results before treatment diastolic blood pressure average 91 and 96 mmHg after treatment average mmHg. Based on the T-test obtained (P value = 0.00 with alpha &lt;0.05). It can be concluded that there is a significant effect between hypertension exercise on decreasing blood pressure. Conclusion: There is an effect of hypertension exercise therapy to lower blood pressure in hypertension sufferers. It is expected that hypertension sufferers can continue hypertension exercise to lower blood pressure.

Understanding “Fear Of Falling” And How It Impacts Older Persons Motivation To Engage In Fall Prevention Exercise Interventions

Abstract Background Fear of falling can cause older persons to restrict their activities, which drives reduced strength and balance and increases their falls risk. Falls can have a significant effect on older persons in terms of loss of confidence, ongoing falls risk and ultimately, a poorer quality of life (Oliver et al, 2010). Fall prevention exercise interventions can help reduce the risk of falling in older adults by up to 34% (Sherrington et al, 2020). This study aims to explore the prevalence of fear of falling in older adults both before and after attending a community-based fall prevention exercise programme. The programme consisted of an evidence-based Physiotherapy led 10-week strength and balance class, followed by a 16-week exercise instructor led strength and balance class. Methods A 2-part qualitative study. Part 1: Prior to commencing the class each participant completed a rating of their fear of falling measured by ConfBal (a validated 10 item Balance Confidence scale). Part 2: Questionnaire assessing their experience of the classes and corresponding change in balance scores. Results 17 older adults completed the programme. Surveys were returned by 8/17 to date (47%). Mean pre-intervention ConfBal score of 20, mean post intervention score of 15 (8/17 participants to date), average 4-point improvement after intervention was statistically significant (p=0.008). Reported benefits of falls prevention exercise classes include peer-peer discussion of functional ability, gaining confidence by exercising in a group environment, practising functional exercises relating to day-to-day tasks, and building social relationships. Conclusion Fear of falling amongst community dwelling older adults is common but group exercise improves confidence as well as boosting social interactions. Participation in fall prevention exercise programmes can help to better support older people as they age which may influence better health outcomes in our communities.

Effects of exercise interventions on cancer-related fatigue in children with cancer: A meta-analysis.

Cancer-related fatigue (CRF) emerges as a common symptom in pediatric cancer patients during treatment. Exercise interventions are increasingly being used as CRF interventions to improve CRF in children with cancer. The objective of this meta-analysis was to synthesize the best available evidence concerning the effectiveness of exercise interventions for cancer-related fatigue in children with cancer. Six databases were extensively searched from inception to December 2023 to identify relevant randomized controlled trials. The risk of bias and methodological quality were assessed using the Cochrane appraisal tool. Pooled effects were calculated using a random-effects model. Heterogeneity was assessed using the I2 test. Eight trials (n = 465) were finally included. Exercise was statistically more effective than conventional care in improving CRF in children with cancer (SMD = -0.62, 95% CI [-1.21, -0.03]) with high statistical heterogeneity (p = .004; I2 = 86%). The results of the subgroup analysis showed that intervention duration <12 weeks (p < .05), exercise frequency ≥ 3 times/week (p < .05), and exercise duration <45 min/time (p < .05) were more effective in improving CRF in children with cancer. Our results suggest that exercise interventions are effective in reducing CRF in children with cancer. We recommend exercise frequency ≥ 3 times/week, exercise duration <45 min/time, and intervention duration <12 weeks.

Exercise Interventions for the Prevention of Sarcopenia After Bariatric Surgery: A Systematic Review

Abstract Purpose Bariatric surgery is a treatment for severe obesity and its associated conditions, which already has ample evidence of its benefits. In addition to the reduction in body fat mass, the weight loss caused by bariatric surgery includes a significant reduction in skeletal muscle and bone mineral mass, which could negatively affect functional capacity and increase the risk of sarcopenia. The need for prophylactic programs that prevent sarcopenia in bariatric surgery patients seems to be one of the crucial points for the long-term surgical success of bariatric and metabolic surgery. This study aims to review the published literature regarding the effects of physical exercise on the prevention of sarcopenia induced by bariatric surgery. Methods We followed the PRISMA checklist for systematic reviews conducted in PubMed/Medline, EBSCO, Web of Science, and Scopus databases. Randomized controlled, controlled clinical, and other types of experimental studies were considered for inclusion. A total of 356 possibly relevant studies were identified with quality considered reasonable and good. Eight studies were included in the review: six of which were randomized experimental studies, one was a pilot study, and one a quasi-experimental study. Results Structured physical exercise allows significant improvements in body composition, positively affecting functional capacity, muscle strength, cardio-metabolic risk factors, and quality of life in patients with obesity undergoing bariatric surgery, especially when combined exercise is implemented in the initial weeks following surgery. Conclusion A combined, individualized, and supervised exercise program contributes to preventing and reducing sarcopenia after bariatric surgery.

Effect of Taichi Exercise on Blood Pressure in a Family with Hypertension in Banjarsengon Village: A Case Study

Hypertension is a critical global health issue that affects quality of life and increases the risk of cardiovascular disease. The purpose of this case study is to assess the efficacy of Taichi exercise as a nonpharmacological therapy for decreasing blood pressure in the family with hypertension. Mrs. H, a 49-year-old single mother with a history of hypertension lived in Banjarsengon Village, Jember. The Taichi exercise intervention was performed twice a week for three weeks. Following six sessions of Taichi exercise, total systolic blood pressure decreased by 10 mmHg and diastolic by 6 mmHg. Family empowerment through the participation of Mrs. H's children in supporting the implementation of Taichi exercise is key in this therapeutic approach. The results of this study suggest that Taichi exercise has potential as a safe and effective alternative therapy for the management of hypertension. In order for the hypertension management program in families to have maximum impact, it is very necessary to increase family empowerment through health workers in community health centers who are monitored periodically.

Disuse atrophy of articular cartilage can be restored by mechanical reloading in mice

BackgroundModerate mechanical stress generated by normal joint loading and movements helps maintain the health of articular cartilage. Despite growing interest in the pathogenesis of cartilage degeneration caused by reduced mechanical stress, its reversibility by mechanical reloading is less understood. This study aimed to investigate the response of articular cartilage exposed to mechanical reloading after unloading in vivo and in vitro.Methods and resultsDisuse atrophy was induced in the knee joint cartilage of adult mice through hindlimb unloading by tail suspension. For in vivo experiments, mice were subjected to reloading with or without daily exercise intervention or surgical destabilization of the knee joint. Microcomputed tomography and histomorphometric analyses were performed on the harvested knee joints. Matrix loss and thinning of articular cartilage due to unloading were fully or partially restored by reloading, and exercise intervention enhanced the restoration. Subchondral bone density decreased by unloading and increased to above-normal levels by reloading. The severity of cartilage damage caused by joint instability was not different even with prior non-weight bearing. For in vitro experiments, articular chondrocytes isolated from the healthy or unloaded joints of the mice were embedded in agarose gel. After dynamic compression loading, the expression levels of anabolic (Sox9, Col2a1, and Acan) and catabolic (Mmp13 and Adamts5) factors of cartilage were analyzed. In chondrocytes isolated from the unloaded joints, similar to those from healthy joints, dynamic compression increased the expression of anabolic factors but suppressed the expression of catabolic factors.ConclusionThe results of this study indicate that the morphological changes in articular cartilage exposed to mechanical unloading may be restored in response to mechanical reloading by shifting extracellular matrix metabolism in chondrocytes to anabolism.

Identifying Clinically Meaningful Muscle Power Enhancements and Their Functional Correlates in Hospitalized Older Patients.

This study aimed to determine the threshold of muscle power and strength enhancements that lead to functional gains after exercise intervention in an acute care unit. A total of 302 older patients (intervention: 169, control: 133) from 2 randomized clinical trials were included (mean age: 86.7 years). We measured maximal strength (1RM) and muscle power via a velocity transducer during leg press exercise at 30% and 60% of 1RM. A multicomponent exercise program, including power training, balance, and gait exercises performed over 3 to 6 consecutive days, served as the intervention. We used an anchor-based method to correlate muscle function increases with the Short Physical Performance Battery (SPPB) and gait velocity (GVT) to define clinically meaningful improvements. In the intervention group, marked differences were found in maximal power at 30% of 1RM between SPPB responders and nonresponders (relative 83.5% vs 34.8%; absolute 33.0 vs 12.8 W; p < .05) and at 60% of 1RM (relative 61.1% vs 22.4%; p < .05). GVT responders demonstrated significantly greater improvements in both relative and absolute maximal power than nonresponders at both 30% and 60% of 1RM (p < .05), as well as greater absolute 1RM gains (21.2 vs 15.2kg, p < .05). Clinically meaningful improvements for muscle power based on SPPB and GVT ranged from 30.2% to 48.7%, whereas for 1RM, it was 8.2% based on GVT. Muscle power gains were most notable in patients with improvements in the SPPB and GVT, highlighting the critical role of muscle power in functional recovery in these patients.

Aerobic exercise and cognitive function in chronic severe traumatic brain injury survivors: a within-subject A-B-A intervention study

BackgroundFollowing acute and sub-acute rehabilitation from severe traumatic brain injury (TBI), minimal to no efficacious interventions to treat ongoing cognitive deficits are available. Aerobic exercise is a non-invasive behavioral intervention with promise to treat cognitive deficits in TBI populations.MethodsSix individuals, aged 24–62 years, with chronic (> 8 months since injury) severe (Glasgow Coma Scale of 3–8) TBI were recruited from two outpatient rehabilitation centers. In an A-B-A study design, 20-weeks of supervised aerobic exercise interventions were delivered three times per week (phase B) in addition to participants typical rehabilitation schedules (phases A). The effect of phase B was tested on a trail making test part B (primary outcome measure of executive function) as well as objective daily physical activity (PA), using both group level (linear mixed effect models) and single subject statistics.ResultsFive of six participants increased trail-making test part B by more than 10% pre-to-post phase B, with three of six making a clinically meaningful improvement (+ 1SD in normative scores). A significant main effect of time was seen with significant improvement in trail-making test part B pre-to-post exercise (phase B). No significant effects in other planned comparisons were found. Statistically significant increases in daily moderate-to-vigorous PA were also seen during phase B compared to phase A with three of six individuals making a significant behaviour change.ConclusionsThe addition of supervised aerobic exercise to typical rehabilitation strategies in chronic survivors of severe TBI can improve executive set shifting abilities and increase voluntary daily PA levels.Trial registrationRetrospective trial registration on July 11 2024 with trial number: ISRCTN17487462.

Adherence to long-term telemonitoring-supported physical activity in patients with chronic heart failure

Chronic heart failure (CHF) is one of the most common diseases with a prevalence of 1–2% in adults, disproportionately affecting the elderly. Despite consistent drug therapy, physical activity (PA) is an integral part of current guidelines. Yet adherence to regular PA and exercise interventions is poor and potential predictors and barriers to PA remain elusive. We examined the effects of a telemonitoring-based exercise intervention in 699 CHF patients in a prospective, randomized-controlled (1:1), multicenter trial. The study was registered in the German Clinical Trials Register under DRKS00019022 on 28.05.2020. For both, the exercise and control group, self-reported PA (MET*h/week) increased and sedentary behavior declined during the 12-month intervention period. In the exercise group, daily step count as analyzed via activity trackers remained stable (pre: 6459 [4016] steps/day, post: 6532 [3858] steps/day; p = 0.621). The average number of completed exercise instruction videos provided via an online application was 1.50 [1.44] videos/week at the beginning and gradually decreased to 1.00 [1.50] videos/week; p < 0.001). Multivariate regression model revealed that exercise-related PA (MET*h/week) and exercise capacity (Wmax) at baseline, CHF severity, atrial fibrillation and age predicted changes in self-reported exercise-related PA (R2 = 0.396). Furthermore, the BMI and the average number of completed videos per week at baseline were associated with the change in completed videos over the course of the study (R2 = 0.251). Our results show the influence of certain baseline characteristics as barriers and predictors of PA progression. Therefore, exercise programs should pay attention to patients’ individual conditions to set achievable goals, and eventually affect the adherence and sustainability of exercise-focused interventions.

Effects of a Physical Exercise Program on Young People and Adults with Autism Spectrum Disorder-A Study Protocol.

Background/Objectives: Physical exercise (PE) has been shown to have positive effects on the symptoms associated with autism spectrum disorder (ASD). However, there is still no consensus on the most appropriate PE intervention model. With this in mind, we developed a program with the aim of determining the effects of PE on physical fitness, with a view to applying it as a potential treatment. Methods: Using an experimental methodology, this research work will recruit 18 institutionalized young people and adults who will be allocated to one of two groups, namely (i) the youth training group and (ii) the adult training group, using low-cost materials. Both intervention groups will perform 90 min of training per session, twice a week, for 12 weeks. Evaluations will be carried out at baseline and month 3. The impact of the exercise program will be assessed based on the variables of anthropometry, body composition, cardiovascular response, and cardiorespiratory fitness. Results: The results of this study will contribute to the development of more effective strategies, prescription recommendations, and interventions as a guarantee in future programs of better and greater adherence to PE by institutionalized individuals with ASD. Conclusions: In addition, we intend to make the PE program available if it promotes positive effects in the target population.

Neurological Aspects of Sarcopenia: A Comprehensive Update on Pathophysiology, Diagnosis, and Therapeutic Advances

Sarcopenia is an age-related disorder characterized by progressive and generalized loss of skeletal muscle tissue. This condition affects approximately 9.9-40.4% of older adults, 2-34% of outpatients, and about 56% of hospitalized patients. Sarcopenia is classified into primary and secondary types, with primary sarcopenia resulting from the natural aging process and secondary sarcopenia caused by various factors such as sedentary lifestyle, disease, and nutrition. The pathophysiology of sarcopenia involves cellular mechanisms, including genetic alterations, telomere erosion, and proteostasis disruption. Mitochondrial dysfunction, epigenetic modifications, and metabolic factors also contribute to the condition. Neurological aspects, such as motor neuron loss and sodium channel dysfunction, play a crucial role in the development of sarcopenia. Prevention and treatment strategies include exercise interventions, nutritional strategies, and pharmacological interventions. Vitamin D supplementation, testosterone replacement therapy, and selective androgen receptor modulators (SARMs) are among the treatments explored. However, these treatments come with potential

Platycodin D and voluntary running synergistically ameliorate memory deficits in 5 × FAD mice via mediating neuromodulation and neuroinflammation.

Alzheimer's disease (AD) is the leading cause of dementia, and currently, no effective treatments are available to reverse or halt its progression in clinical practice. Although a plethora of studies have highlighted the benefits of physical exercise in combating AD, elder individuals often have limited exercise capacity. Therefore, mild physical exercise and nutritional interventions represent potential strategies for preventing and mitigating neurodegenerative diseases. Our research, along with other studies, have demonstrated that platycodin D (PD) or its metabolite, platycodigenin, derived from the medicinal plant Platycodon grandiflorus, exerts neuroprotective effects against amyloid β (Aβ)-induced neuroinflammation. However, the combined effects of PD and physical exercise on alleviating AD have yet to be explored. The current study aimed to investigate whether combined therapy could synergistically ameliorate memory deficits and AD pathology in 5 × FAD mice. Five-month-old 5 × FAD mice were randomly assigned to four groups, and received either PD (5 mg/kg/day, p.o.), voluntary running, or a combination of both for 47 days. Nest building test, locomotion test, and Morris water maze test were used to evaluate the cognitive function. Immunohistochemical and ELISA analysis was performed to determine Aβ build-up, microglia and astrocytes hyperactivation, and survival neurons in the hippocampus and perirhinal cortex. Real-time quantitative PCR analysis was used to assess the polarization of microglia and astrocytes. HPLC analysis was performed to measure monoamine neurotransmitters in the hippocampus. The combination of PD and voluntary running synergistically restored nest-building behavior, alleviated recognition and spatial memory deficits, and showed superior effects compared to monotherapy. In addition, the PD and voluntary running combination reduced Aβ build-up, decreased hyperactivation of microglia and astrocytes in the hippocampus and perirhinal cortex, promoted the polarization of inflammatory M1 microglia and reactive astrocytes toward beneficial phenotypes, and lowered systemic circulating pro-inflammatory cytokines while increasing anti-inflammatory cytokines in 5 × FAD mice. Furthermore, combined therapy effectively protected neurons and increased levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in the hippocampus of 5 × FAD mice. In conclusion, the combination of PD and voluntary running holds great potential as a treatment for AD, offering promise for delaying onset or progression of AD.
