The effects of visual information deprivation and feedback balance training on balance in patients with stroke.

Patients with stroke depend on visual information due to balance deficits. Therefore, it is believed that appropriate visual deprivation training could have an impact on improving balance abilities. The purpose of this study was to compare the effects of balance training performed in visual deprivation and feedback conditions on balance in stroke survivors. The 39 participants were randomly assigned to either the Visual Deprivation Group (VDG; n = 13), the Visual Feedback Group (VFG; n = 13), or the Control Group (CG; n = 13). The training sessions were conducted five times a week for three weeks. Participants completed the Berg Balance Scale (BBS), Timed Up and Go test (TUG), Four Square Step Test (FSST), and Limit of Stability (LOS) assessments. The VDG showed significant improvements in BBS, FSST, TUG, and LOS. In VFG, significant improvements were observed in BBS and TUG. There were statistically significant differences among the groups in all variables related to balance. The results of this study suggest that balance training under visual deprivation is effective in improving static and dynamic balance and gait in patients with stroke. In other words, patients with stroke need to reduce their over-reliance on visual information.

Exercise Effects on Maternal Vascular Health and Blood Pressure during Pregnancy and Postpartum: A Systematic Review and Meta-Analysis.

This systematic review aimed to assess the effects of exercise training during pregnancy and the postpartum period on maternal vascular health and blood pressure (BP). The outcome of interest were pulse wave velocity (PWV), flow-mediated dilation (FMD), and BP from pregnancy until 1-year postpartum. Five databases, including Ovid MEDLINE, EMBASE, CINAHL, Web of Science, and Cochrane Library, were systematically searched from inception to August 2023. Studies of randomized controlled trials (RCTs) comparing the effects of prenatal or postpartum exercise to a non-exercise control group were included. The risk of bias and the certainty of evidence were assessed. Random-effects meta-analyses and sensitivity analyses were conducted. In total, 20 RCTs involving 1,221 women were included. Exercise training, initiated from week 8 during gestation or between 6-14 weeks after delivery, with the program lasting for a minimum of 4 weeks up to 6 months, showed no significant impact on PWV and FMD. However, it resulted in a significant reduction in systolic BP (SBP) (MD: -4.37 mmHg; 95% CI: -7.48 to -1.26; p = 0.006) and diastolic BP (DBP) (MD: -2.94 mmHg; 95% CI: -5.17 to -0.71; p = 0.01) with very low certainty. Subgroup analyses revealed consistent trends across different gestational stages, types of exercise, weekly exercise times, and training periods. Exercise training during pregnancy and the postpartum period demonstrates a favorable effect on reducing maternal BP. However, further investigations with rigorous methodologies and larger sample sizes are needed to strengthen these conclusions.

A Pilot Study of the Effectiveness of Cognitive Resilience Training on Anxiety, Depression, and Suicidal Ideation Among Students of a Selected University in Mexico

ABSTRACT Mental distress burdens student populations; meanwhile, intervention-based studies are insufficient. This pilot study examined the effectiveness of cognitive resilience training (CRT) in enhancing students’ mental health. This experimental design study recruited 29 participants (mean age = 21.70; SD = 2.55) from the Autonomous University of Ciudad Juarez (UACJ) in northern Mexico. A questionnaire pack containing the General Anxiety Disorder-2, Patient Health Questionnaire-2, Plutchik Suicide Risk Scale, and Brief Resilience Scale was utilized. At the pretest, there was no significant difference between the experimental group (EG) and the control group (CG). At the posttest, the CG scored higher on anxiety, depression, and suicidal ideation compared to its EG counterparts. However, the EG’s participants exhibited higher resilience, leading to a reduction in mental distress compared to their control group counterparts. The study concluded that CRT is an effective intervention for enhancing students’ mental health. Therefore, it is recommended for use in university clinical settings.

Resistance training and combined resistance and aerobic training as a treatment of depression and anxiety symptoms in young people: A systematic review and meta-analysis.

To determine the treatment effect of resistance training in reducing symptoms of anxiety and depression in young people. We searched MEDLINE, PsychINFO, and PubMed for articles published in English from January 1980 to September 2023 for randomized controlled trials (RCT) that included at least 4 weeks of resistance training, with participants aged 26 years or younger with clinically elevated anxiety and depression symptoms. A random-effects meta-analysis was used to calculate a pooled effect size of resistance training pre-and post-intervention compared to control groups. The quality of evidence was assessed using the Cochrane risk-of-bias 2 (RoB 2) and Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria. Ten RCTs involving 376 participants (209 females and 127 males) across educational, clinical, and community based setting were eligible for inclusion in the analysis. Resistance training was associated with a significant reduction in depressive (Hedge's g = -1.06, 95% CI -1.61 to -0.51, p < .001) and anxiety (Hedge's g = -1.02, 95% CI -1.50 to -0.54, p < .001) symptoms. Substantial heterogeneity was observed in the analysis of depression symptoms (I2 = 79%) and anxiety symptoms (I2 = 66%). Six trials had a low risk of bias, four trials showed some concerns. The GRADE analysis demonstrated a high level of certainty for depressive symptoms and a moderate level for anxiety symptoms. Resistance training is an effective intervention in reducing depression and anxiety symptoms in young people, delivered across a range of settings. Future trials exploring the effect resistance training interventions with long-term follow up are warranted to understand the outcomes.

Effect of Heat Acclimatization, Heat Acclimation, and Intermittent Heat Training on Maximal Oxygen Uptake.

Maximal oxygen uptake (VO2max) is an important determinant of endurance performance. Heat acclimation/acclimatization (HA/HAz) elicits improvements in endurance performance. Upon heat exposure reduction, intermittent heat training (IHT) may alleviate HA/HAz adaptation decay; however, corresponding VO2max responses are unknown. VO2max is maintained after HAz/HA; IHT mitigates decrements in aerobic power after HAz/HA. Interventional study. Level 3. A total of 27 male endurance runners (mean ± SD; age, 36 ± 12 years; body mass, 73.03 ± 8.97 kg; height, 178.81 ± 6.39 cm) completed VO2max testing at 5 timepoints; baseline, post-HAz, post-HA, and weeks 4 and 8 of IHT (IHT4, IHT8). After baseline testing, participants completed HAz, preceded by 5 days of HA involving exercise to induce hyperthermia for 60 minutes in the heat (ambient temperature, 39.13 ± 1.37°C; relative humidity, 51.08 ± 8.42%). Participants were assigned randomly to 1 of 3 IHT groups: once-weekly, twice-weekly, or no IHT. Differences in VO2max, velocity at VO2max (vVO2), and maximal heart rate (HRmax) at all 5 timepoints were analyzed using repeated-measure analyses of variance with Bonferroni corrections post hoc. No significant VO2max or vVO2 differences were observed between baseline, post-HAz, or post-HA (P = 0.36 and P = 0.09, respectively). No significant group or time effects were identified for VO2max or vVO2 at post-HA, IHT4, and IHT8 (P = 0.67 and P = 0.21, respectively). Significant HRmax differences were observed between baseline and post-HA tests (P < 0.01). No significant group or time HRmax differences shown for post-HA, IHT4, and IHT8 (P = 0.59). VO2max was not reduced among endurance runners after HA/HAz and IHT potentially due to participants' similar aerobic training status and high aerobic fitness levels. HAz/HA and IHT maintain aerobic power in endurance runners, with HAz/HA procuring reductions in HRmax.

The accuracy of shooting petanque iron balls: Effectiveness of resistance band training

Background Problems: There is an integration of strategy, calmness, and accuracy in petanque. Various training forms focus on several parts of the arm muscles to increase the stability of the arm muscles and the ability to throw the ball on target, however, no one has developed a training method that can enhance both accuracy and muscular strength. Research Objectives: This research aims to determine the effect of resistance band exercises on shooting accuracy in petanque athletes. Methods: This research employed a quasi-experimental method with a pretest-posttest approach and a control group design. The research subjects were divided into two groups (experimental and control) and given different treatments. The total number of research subjects consisted of 40 athletes with an average age of 21.43  ± 2.48, a weight 56.07  ± 2.33, a height 170.41  ± 5.12, and a BMI 19.86  ± 2.56. Data analysis was tested using a one-way ANOVA to compare the two groups. Findings and Results: The research results indicated that resistance band exercises for 16 weeks had a positive and statistically significant impact on increasing shooting accuracy in the experimental group compared to the control group in petanque athletes. Thus, this research has provided evidence and recommendations for athletes and coaches that specific recommendations to improve throwing accuracy in petanque must be added with the contribution of strength training with resistance bands. Conclusion: The combination of resistance bands with other forms of accuracy training is also recommended for further research so that options for implementing strength training related to throwing accuracy become more varied to help improve petanque performance. This study can be used as a starting point for training variations that are documented in the literature, which can help coaches and athletes develop skills-related fitness components for the purpose of improving shooting accuracy capabilities in petanque.

The effectiveness of strength training and coordination exercises in improving older individuals' autonomy and well being is investigated in this systematic study. This review assesses the effect of these exercise interventions on a range of outcomes, including muscle strength, balance, mobility, fall prevention, and overall quality of life. It does this by thoroughly analysing the body of existing literature, which includes randomized controlled trials, systematic reviews, and meta analyses. Further, the synergistic effects of combining exercises for coordination and strength are examined, along with practical considerations and future areas for research. The results of this analysis demonstrate the substantial benefits of strength training and coordination activities for encouraging healthy aging and enhancing function.

Cardiac Dynamics in Auditory-Motor Synchronization: Roles of Short-Term Training and Rhythm Complexity

ABSTRACT Previous findings suggest that long-term musical training and rhythm complexity may affect performers’ auditory-motor synchrony and their cardiac rhythms. We investigated the effects of short-term training and rhythm complexity on auditory-motor synchronization and cardiac activity as individuals synchronized with auditory rhythms. Forty-two adult participants synchronized their taps with sounded rhythms to form a 2:3 duration ratio (stimulus duration:tap duration) or a 3:2 duration ratio (tap rate held constant across rhythms). Participants received short training with one rhythm and received longer training with the other rhythm. Then, participants completed five experimental trials in which they synchronized their sounded taps with the stimulus rhythm. Cardiac activity was recorded during synchronization. Tapping synchronization was less accurate and more variable for the 3:2 rhythm than the 2:3 rhythm. Linear measures of cardiac activity showed less high-frequency variability during the 3:2 rhythm than the 2:3 rhythm. Behavioral-cardiac correspondences emerged with training: Poorer synchronization was associated with more variable cardiac activity after long training, but not after short training. Finally, there were consistent individual differences in cardiac recurrence and predictability across training conditions. These findings demonstrate both short-term learning effects and rhythm complexity effects on cardiac dynamics during auditory-motor synchronization.

Facebook Challenge: Integration of Breastfeeding for Sick Babies and E-Training to Enhance the Knowledge of Healthcare Workers

Background Although the Thailand Breastfeeding Center has supported breastfeeding for sick babies since 2014, it has been found that breastfeeding in infants is still 40% lower than national targets. Objective This research aimed to test the effectiveness of online breastfeeding training through social media to further the knowledge of healthcare workers. Methods A quasi-experimental research study of a sample group of 60 workers was conducted between the neonatal step-down unit and the postpartum care unit. Research instruments consisted of breastfeeding e-training through a Facebook platform, knowledge testing on the breastfeeding of sick newborns, an online training satisfaction assessment form, data analysis by frequency and percentage, averaging, and testing by t-test, chi-square, and the Fisher exact test. Results The mean and standard deviation of knowledge before training in the experiment and control group were 22.40±2.11and 23.43±3.32, respectively. After the intervention, the experimental group was 31.93±1.98, and the control group was 24.06±2.14. It was found that the average knowledge score pertaining to the breastfeeding of high-risk neonates in the group that had undergone online training was higher than the group that had undergone ordinary supervision (p&lt; 0.001). Conclusion It can be seen that asynchronous e-training may be one alternative for the knowledge development of healthcare workers in promoting breastfeeding for families with sick newborns.

Changes in the hippocampal level of tau but not beta-amyloid may mediate anxiety-like behavior improvement ensuing from exercise in diabetic female rats

BackgroundIn the present study, we investigated the effect of high-intensity interval training (HIIT) on cognitive behaviors in female rats with a high-fat diet + streptozotocin (STZ)-induced type 2 diabetes.MethodsTwenty-four female rats were divided into four groups randomly (n = 6): control (C), control + exercise (Co + EX), diabetes mellitus (type 2) (T2D), and diabetes mellitus + exercise (T2D + EX). Diabetes was induced by a two-month high-fat diet and a single dose of STZ (35 mg/kg) in the T2D and T2D + EX groups. The Co + EX and T2D + EX groups performed HIIT for eight weeks (five sessions per week, running on a treadmill at 80–100% of VMax, 4–10 intervals). Elevated plus maze (EPM) and open field test (OFT) were used for assessing anxiety-like behaviors, and passive avoidance test (PAT) and Morris water maze (MWM) were applied for evaluating learning and memory. The hippocampal levels of beta-amyloid (Aβ) and Tau were also assessed using Western blot.ResultsAn increase in fasting blood glucose (FBG), hippocampal level of Tau, and a decrease in the percentage of open arm time (%OAT) as an index of anxiety-like behavior were seen in the female diabetic rats which could be reversed by HIIT. In addition, T2D led to a significant decrease in rearing and grooming in the OFT. No significant difference among groups was seen for the latency time in the PAT and learning and memory in the MWM.ConclusionsHIIT could improve anxiety-like behavior at least in part through changes in hippocampal levels of Tau.

Purpose: The study aimed to investigate the effect of circuit training on sleep and cognition in collegiate with poor sleep quality. Methods: The present study was conducted among 30 subjects having poor sleep quality, who were randomly allocated via lottery method to either a circuit training group or a control group i.e., a treadmill running group. The intervention was given for 3 weeks, with 3 sessions of 30 minutes per week each. Subjects were assessed for poor sleep and cognition at the beginning and end of the 3rd week. Result: 3 weeks of circuit training showed significant improvement in sleep and also in working memory and attention. Conclusion: Insufficient sleep is prevailing among college students. Due of their accessibility and minimal danger, non-pharmacological methods are advised. Given the findings of the present study, dynamic circuit training should be recommended as a practical approach to improve poor sleep and cognition in collegiate students

Effect of low-volume combined aerobic and resistance high-intensity interval training on vascular health in people with type 2 diabetes: a randomised controlled trial.

We compared the effects of low-volume combined aerobic and resistance high-intensity interval training (C-HIIT), combined moderate-intensity continuous training (C-MICT) and waitlist control (CON) on vascular health after 8-weeks of supervised training, and an additional 10-months of self-directed training, in adults with type 2 diabetes (T2D). Sixty-nine low active adults with T2D were randomised to 8-weeks of supervised C-HIIT (3 times/week, 78-min/week), C-MICT (current exercise guidelines, 4 times/week, 210-min/week) or CON. CON underwent usual care for 8-weeks before being re-randomised to C-HIIT or C-MICT. This was followed by 10-months of self-directed training for participants in C-HIIT and C-MICT. Vascular outcomes were evaluated at baseline, 8-weeks, and 12-months. After 8-weeks, supervised C-HIIT significantly improved relative flow-mediated dilation (FMD) compared with CON (mean difference [MD] 0.8% [0.1, 1.4], p = 0.025). Although not significantly different from CON, the magnitude of change in relative FMD following 8-weeks of supervised C-MICT was similar (MD 0.8% [-0.1, 1.7], p = 0.080). There were no differences in haemodynamic indices, carotid-femoral pulse wave velocity (cfPWV), or aortic reservoir pressure between groups at 8-weeks. After 12-months, there was a significant reduction in haemodynamic indices (time effect, p < 0.05) for both C-HIIT and C-MICT, with no between-group difference. The reduction in cfPWV over 12-months was significantly greater in C-MICT than C-HIIT (group × time effect, p = 0.018). There was no difference in FMD over time or between groups at 12-months. Short-term supervised C-HIIT and C-MICT both increased brachial artery FMD compared with CON. Long-term C-HIIT and C-MICT were beneficial for improving haemodynamic indices, but not brachial artery FMD. C-MICT was superior to C-HIIT for improving cfPWV at 12-months.

A Hybrid Image Augmentation Technique for User- and Environment-Independent Hand Gesture Recognition Based on Deep Learning

This research stems from the increasing use of hand gestures in various applications, such as sign language recognition to electronic device control. The focus is the importance of accuracy and robustness in recognizing hand gestures to avoid misinterpretation and instruction errors. However, many experiments on hand gesture recognition are conducted in limited laboratory environments, which do not fully reflect the everyday use of hand gestures. Therefore, the importance of an ideal background in hand gesture recognition, involving only the signer without any distracting background, is highlighted. In the real world, the use of hand gestures involves various unique environmental conditions, including differences in background colors, varying lighting conditions, and different hand gesture positions. However, the datasets available to train hand gesture recognition models often lack sufficient variability, thereby hindering the development of accurate and adaptable systems. This research aims to develop a robust hand gesture recognition model capable of operating effectively in diverse real-world environments. By leveraging deep learning-based image augmentation techniques, the study seeks to enhance the accuracy of hand gesture recognition by simulating various environmental conditions. Through data duplication and augmentation methods, including background, geometric, and lighting adjustments, the diversity of the primary dataset is expanded to improve the effectiveness of model training. It is important to note that the utilization of the green screen technique, combined with geometric and lighting augmentation, significantly contributes to the model’s ability to recognize hand gestures accurately. The research results show a significant improvement in accuracy, especially with implementing the proposed green screen technique, underscoring its effectiveness in adapting to various environmental contexts. Additionally, the study emphasizes the importance of adjusting augmentation techniques to the dataset’s characteristics for optimal performance. These findings provide valuable insights into the practical application of hand gesture recognition technology and pave the way for further research in tailoring techniques to datasets with varying complexities and environmental variations.

The effect of pelvic floor muscle training in men with benign prostatic hyperplasia and overactive bladder

BackgroundMen with overactive bladder (OAB) and benign prostatic hyperplasia (BPH), will have deterioration in the quality of life.ObjectiveThe aim of this study was to evaluate the effect of combining pelvic floor muscle training with the urgency suppression technique (PFMT-st) and silodosin in comparison with silodosin in men with benign prostatic hyperplasia (BPH) and overactive bladder (OAB) after 12 weeks of treatment.Patients and methodsA total of 158 patients were randomized into two groups. The control group received oral silodosin at a daily dose of 8 mg. The experimental group was administered PFMT-st and silodosin. The evaluation methods included the number of voids and intensity of urgencies over 24 h using a micturition diary, the International Prostate Symptom Score (IPSS), the Overactive Bladder Questionnaire (OAB-q), and the patient global impression of improvement (PGI-I).Results142 of 172 (86.6%) men were assessed (70 in the control group, 72 in the experimental group). The significant changes were in favor of the experimental group (p < 0.001) in the number of voids per 24 h (− 1.95 ± 1.94 vs. − 0.90 ± 1.44), the OAB-q symptom score (− 14.25 ± 10.05 vs. − 9.28 ± 10.60), the intensity of urgencies (− 0.97 ± 0.53 vs. 0.24 ± 0.57), the IPSS (− 4.59 ± 3.00 vs. − 2.30 ± 3.63), and in the PGI-I (2.24 ± 0.79 vs. 3.60 ± 0.92).ConclusionsThe addition of PFMT-st to silodosin treatment significantly improved OAB in men with BPH. This is the first study to confirm that PFMT-st should be the first-choice treatment for OAB in BPH.

Simple Randomised Controlled Trial Comparison of Effect of Suspension Training and Plyometric Training on Dynamic Balance and Vertical Jump in Competitive Basketball Players

Objectives:To assess dynamic balance and vertical jump pre and post Suspension training and Plyometrictraining in competitive basketball players. Methods:24 basketball players aged 18-24 were selected and randomly assigned to threegroups namely Suspension training, Plyometrics and the control group. Supervised sessions were held for 8 weeks, 2 times a week for 45 minutes. Pre and post assessment for dynamic balance and vertical jump was done. Results:  Suspension training and Plyometric training both have shown a positive effect on dynamic balance( p &lt;0.007 ) except for anterior direction and vertical jump (p &lt;0.007) in basketball players. The results of the control group have shown a lot of variability as no specific training was given for dynamic balance and vertical jump. Conclusion:Suspension training and Plyometric training have positive effect on dynamic balance and vertical jump height. However, no training method is found to be more efficient than the other.

Single-Session Cerebellar Transcranial Direct Current Stimulation Improves Postural Stability and Reduces Ataxia Symptoms in Spinocerebellar Ataxia.

Spinocerebellar ataxia (SCA) results in balance and coordination impairment, and current treatments have limited efficacy. Recent evidence suggests that combining postural training with cerebellar transcranial direct current stimulation (ctDCS) can improve these symptoms. However, the combined effects of ctDCS and postural training on individuals with spinocerebellar ataxia remain underexplored. Ten volunteers with (SCA type 3) participated in a triple-blind, randomized, crossover study to receive a single session of ctDCS (2mA for 20min) and a sham ctDCS session separated by at least one week. The Biodex Balance System was used to assess balance at each session, measuring overall stability index, anteroposterior stability index, and medial-lateral stability index. As secondary outcomes, cerebellar ataxia symptoms were evaluated using the 8-item Scale for Assessment and Rating of Ataxia. The assessments were conducted before and after each session. The results indicated that ctDCS enhanced the overall stability index when compared to sham ctDCS (Z = -2.10, p = 0.03), although it did not significantly affect the anteroposterior or medial-lateral stability indices. Compared to the baseline, a single session of ctDCS reduced appendicular symptoms related to cerebellar ataxia, as evidenced by improvements in the nose-finger test (Z = -2.07, p = 0.04), fast alternating hand movements (Z = -2.15, p = 0.03), and heel-to-shin slide (Z = -1.91, p = 0.05). In conclusion, our study suggests that a single session of ctDCS, in combination with postural training, can enhance balance and alleviate ataxia symptoms in individuals with cerebellar ataxia. This study was approved by the local research ethics committee (No. 2.877.813) and registered on clinicaltrials.org (NCT04039048 - https://www.clinicaltrials.gov/study/NCT04039048 ) on 2019-07-28.

Effects of Mindfulness Training on Stress Reduction and Well-being in the Workplace

Purpose: The general objective of this study was to the effects of mindfulness training on stress reduction and well- being in the workplace. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to the effects of mindfulness training on stress reduction and well- being in the workplace. Various studies demonstrated that employees who underwent mindfulness programs reported lower stress levels, improved emotional well-being, increased job satisfaction, and a positive organizational culture. These findings supported the integration of mindfulness practices into workplace wellness initiatives, providing employees with effective tools for managing stress and fostering a healthier work environment. The studies highlighted mindfulness as a valuable intervention for enhancing both individual well-being and organizational outcomes. Unique Contribution to Theory, Practice and Policy: The Self- Determination theory, Conservation of Resources (COR) theory and Job Demands- Resource (JD-R) model may be used to anchor future studies on the effects of mindfulness training on stress reduction and well- being in the workplace. The study made significant contributions to theory, practice, and policy. It validated and expanded theories such as Self-Determination Theory (SDT) and Conservation of Resources (COR) Theory, demonstrating how mindfulness fulfills intrinsic needs and serves as a resource for managing job demands. Recommendations for practice included continuous and tailored mindfulness programs for organizations to integrate into workplace wellness initiatives. Policy implications emphasized the cost-effectiveness of mindfulness interventions and the need for their inclusion in corporate wellness policies. The study also highlighted directions for future research, including longitudinal studies and exploration of the mechanisms through which mindfulness influences organizational factors. Ethical considerations were addressed, emphasizing voluntary participation and privacy. Overall, the study provided a roadmap for organizations to create healthier, more resilient workplaces through mindfulness training.

The effectiveness of virtual reality training on knowledge, skills and attitudes of health care professionals and students in assessing and treating mental health disorders: a systematic review

Background Virtual reality (VR) training can enhance health professionals’ learning. However, there are ambiguous findings on the effectiveness of VR as an educational tool in mental health. We therefore reviewed the existing literature on the effectiveness of VR training on health professionals’ knowledge, skills, and attitudes in assessing and treating patients with mental health disorders.MethodsWe searched MEDLINE, PsycINFO (via Ovid), the Cochrane Library, ERIC, CINAHL (on EBSCOhost), Web of Science Core Collection, and the Scopus database for studies published from January 1985 to July 2023. We included all studies evaluating the effect of VR training interventions on attitudes, knowledge, and skills pertinent to the assessment and treatment of mental health disorders and published in English or Scandinavian languages. The quality of the evidence in randomized controlled trials was assessed with the Cochrane Risk of Bias Tool 2.0. For non-randomized studies, we assessed the quality of the studies with the ROBINS-I tool.ResultsOf 4170 unique records identified, eight studies were eligible. The four randomized controlled trials were assessed as having some concern or a high risk of overall bias. The four non-randomized studies were assessed as having a moderate to serious overall risk of bias. Of the eight included studies, four used a virtual standardized patient design to simulate training situations, two studies used interactive patient scenario training designs, while two studies used a virtual patient game design. The results suggest that VR training interventions can promote knowledge and skills acquisition.ConclusionsThe findings indicate that VR interventions can effectively train health care personnel to acquire knowledge and skills in the assessment and treatment of mental health disorders. However, study heterogeneity, prevalence of small sample sizes, and many studies with a high or serious risk of bias suggest an uncertain evidence base. Future research on the effectiveness of VR training should include assessment of immersive VR training designs and a focus on more robust studies with larger sample sizes.Trial registrationThis review was pre-registered in the Open Science Framework register with the ID-number Z8EDK.

The Effect of Endurance Training with Garlic and Stevia Supplementation on AgRP and α-MSH in Brain Tissue of Obese Wistar Rats

Background: The aim of this study is to investigate the effect of endurance training with garlic and stevia supplementation on AgRP and α-MSH in the brain tissue of obese Wistar rats. Methods: 36 obese male Wistar rats fed with a high-fat diet (24 g fat, 24 g protein, and 41 g carbohydrate/100 g) were divided into six groups, including: 1) sham; 2) stevia supplementation; 3) garlic supplementation; 4) endurance training; 5) stevia supplementation plus endurance training, and 6) garlic supplementation plus endurance training. Moreover, 6 rats were included in the healthy control group to investigate the effects of obesity on the research variable. Training groups performed incremental endurance training for 15-50 minutes at a speed of 15-25 m/min, for eight weeks. Garlic and stevia supplements were added to the diet of the supplementation groups at a dose of 250 mg/kg. Results: Levels of AgRP in stevia supplementation group were significantly higher than endurance training (P=0.019) and endurance training plus stevia supplementation (P=0.018) groups. Levels of α-MSH in the garlic supplementation (P=0.001), endurance training (P=0.002), stevia supplementation plus endurance training (P=0.001), and garlic supplementation plus endurance training (P=0.001) groups were significantly higher than the sham group. In addition, in the endurance training plus stevia supplementation group, the levels were significantly higher than the stevia supplementation group (P=0.002). Conclusion: Endurance training plus garlic supplementation as well as endurance training plus stevia supplementation seem to play a synergistic role in appetite control protein; however, more studies on AgRP changes, following training and garlic and stevia supplementation are needed.
