Introduction: Exercise plays an important role in promoting cardiovascular function. Also concurrent endurance and resistance training can have different effects on the heart. The purpose of this study was to investigate the effect of endurance, resistance and concurrent resistance and endurance training on the heart structure of healthy middle-aged women. Materials and Methods: Forty healthy middle-aged women (mean age 44. 62± 3. 45 years, height 157. 75± 4. 87 cm and weight 73. 27± 10. 64 kg) were randomly divided into four groups (10 people in each group): Control, Endurance, Strength and Concurrent. The training program was conducted in a period of eight weeks, three sessions per week. Endurance group were running on the treadmill incrementally. The resistance group performed eight exercises incrementally in each session. The concurrent group performed half of both endurance and resistance training in each session. Left ventricular end diastolic and systolic diameters, post-wall thickness, septum wall thickness and left ventricular mass were measured by m-mode and 2-D echocardiography. Results: The end systolic diameter in the concurrent group and end diastolic diameter and left ventricular mass in endurance and concurrent groups were significantly increased compared to pre-training (P≤ 0. 05). The left ventricular mass in the endurance and concurrent group was significantly different from that of the control group (P≤ 0. 05). Conclusion: It can be concluded that concurrent endurance and resistance training is effective in making some structural adaptations of the heart in middle-aged women.

Introduction: The balance between physical activity, medication, and daily food intake helps to regulate blood sugar in people with type 2 diabetes. The aim of this study was to investigate the effect of twelve weeks of combined exercise with Canagliflozin on the development of insulin resistance factors in type 2 diabetic men. Materials and Methods: In this quasi-experimental study, 44 men with type 2 diabetes (mean age 25-40 years) from Tehran city in 2019 were randomly divided into four groups (n=11) of control, drug, exercise and exercise-drug groups. Combined exercises were performed 3 sessions per week, 45 minutes for 12 weeks. Subjects were given 200 mg of canagliflozin for 12 weeks. Blood samples and anthropometric characteristics were obtained before and 24 hours after the intervention at 12-hour fasting. Data were analyzed using two-way ANOVA with repeated measures, t-test and Bonferroni post hoc test at P<0. 05. Results: Results showed that 12-week training-canagliflozin administration significantly decreased leptin and IL-6 levels in type 2 diabetic men (p=0. 001). Also, the levels of leptin (P=0. 002), TNF-α (P=0. 004) and IL-6 (P<0. 001) were significantly lower than the pre-test. Conclusion: Regarding the benefits of canagliflozin as a supplement for diabetic patients, it can have a more effect on the improvement of diabetes and related diseases.

Introduction: Nursing students are consuming fast foods despite studying medical science. Nursingstudents are susceptible to significant micronutrients such as folic acid (folate) due to the high volume oftraining and theoretical courses. The aim of this study was to determine the relationship between fast foodintake and serum folic acid level in nursing undergraduate students of Islamic Azad University, Medical Sciences Tehran Branch. Materials and Methods: The present study was a descriptive correlational study performed that was performed on 100 undergraduate nursing students of Islamic Azad University who were selected throughsimple sampling method. Data were collected through demographic questionnaire, a researcher-made questionnaire on fast food consumption and eating habits and blood test. Data were analyzed with SPSS20 software and descriptive statistics and independent t-test and one-way ANOVA. Results: The results showed that 56% of the subjects were female and 44% male. There was a significant negative relationship between fast food intake (except chicken nuggets, fish and shrimp) and serum folic acid level (p<0. 05). There was no significant relationship between dietary habits of fast food and serumfolic acid level (p=0. 57). Conclusion: The results of the present study showed a low level of serum folic acid and a significant intake of fast foods in nursing students. It is necessary to increase the level of knowledge and attitude towards ready meals, use of folic acid supplements as a result of serum folate test and doctor's order, andreduce the consumption of ready meals in nursing students.

Introduction: Obesity and cardiovascular disease are among the leading causes of mortality in the world. The aim of the present study was to determine the effect of aerobic training on some antioxidant and cardiac oxidative stress in male rats with two types of normal and cholesterol-rich diet. Materials and Methods: 40 male Wistar rats randomly divided into four groups of normal-control, normal-exercise, cholesterol-rich and cholesterol-exercises. The training groups performed 12 weeks (5 days a week) of endurance training. Prior to the beginning of the training period, the cholesterol-rich diet group rats were fed this diet for three months to induce hyperlipidemia and dietary intervention was administered until the end of the training period. 48 hours after the last training session, they were killed and then their heart tissues were separated and the experiments were performed. Results: Between groups analyses indicated a significant difference between groups consuming cholesterol and normal foods in the MDA (P = 0. 001), TAC (P = 0. 004) and glutathione (P = 0. 013). Conclusion: The results of this study showed that moderate-intensity aerobic activity improved oxidative stress indices and increased TAC in the hearts of mice with normal and high cholesterol diet.

Introduction: Diabetes is one of the leading causes of mortality in developing countries. The aim of this study was to investigate The effect of broccoli powder supplementation along with combined exercise training on some cardiovascular risk factors and insulin resistance in men with type 2 diabetes. Materials and Methods: For this purpose, 44 volunteer diabetic men after homogenization based on individual characteristics were randomly divided into 4 groups of 11 individuals including exercisesupplement group, exercise-placebo group (exercise), control-supplement group (supplement), controlplacebo (controls. Combined exercise program included 12 weeks, three sessions per week. Broccoli supplement was also 10 grams per day for 12 weeks. Results: Between analysis showed that there was a significant difference between the groups of control with another groups in fibrinogen (P=0. 008), viscosity (P=0. 029) and insulin resistance (P=0. 007). Significant changes in the measured indices were also observed in the within-group of supplement, exercise and exercise-supplement changes (P <0. 05). Conclusion: The results of this study showed that 12 weeks of combined exercise with broccoli supplement significantly reduced fibrinogen, viscosity, blood glucose and insulin resistance in all three groups of exercise-supplement, exercise and supplement. Therefore, incorporating broccoli into the diet can partially prevent the risky effects of type 2 diabetes.

Introduction: Emotional reactivity has a role in the creation and continuation of many psychological disorders, but the measurement tools of this component are limited. The purpose of this study was to assess the psychometric adequacy of the Persian version of the Emotional Reaction Scale (ERS). Method: This is a descriptive cross-sectional study. The sample consisted of 300 students of Kashan University who were selected by cluster sampling. Instruments used were Emotional Reactivity Questionnaires (ERS), Health Anxiety Inventory (F-SHAI), Anxiety Sensitivity (ASI), and Carver & White Behavioral Inhibition/Inhibition Systems (BAS/BIS). The questionnaire was constructed using Approach and exploratory factor analysis method was investigated. Also, convergent validity was assessed by Health Anxiety Inventory (F-SHAI, ASI Anxiety Sensitivity Questionnaire) and Carver & White Behavioral Inhibition /Inhibition System (BAS/BIS), and the reliability of the test and internal consistency of the questionnaire. Results: The results of the confirmatory factor analysis indicated that the three factor model of the questionnaire was not approved. The results of exploratory factor analysis confirmed the four factors: emotional response speed, emotional intensity, emotional persistence and emotional sensitivity. Also, the convergence credibility of this questionnaire was good with anxiety inventory (0. 33), anxiety sensitivity (0. 41). The correlation of Behavioral Inhibition / Behavioral Inventory Questionnaire (BAS / BIS) was not significant, which indicates a divergent scale validity. The internal consistency and reliability of the test were 0. 92 and 0. 72 respectively. Conclusion: The Emotional Reactivity Scale (ERS) is suitable for measuring the severity, speed, sensitivity and emotional persistence of Iranian adults, and is a suitable instrument with good psychometric qualities.

Introduction: Sexual abuse is one of the phenomena causing significant psychological problems for adolescents. The aim of this study was to determine the effectiveness of integrative acceptance and commitment-cognitive behavioral therapy and parent management training on the depression and anxiety of adolescent boy with sexual abuse. Materials and Methods: The research method was quasi-experimental, and research design was a three group design. 45 male adolescents were selected by purposive sampling method in Isfahan in 2018 and were randomly assigned to two experimental and one control group (each group 15 persons). Data were collected through depression and anxiety questionnaires at three time points before, after and two months later (follow up). The integrative acceptance and commitment-cognitive behavioral therapy and parent management training received treatment in 10 sessions. The data were analyzed through repeated measure analysis of variance and post-hoc Bonferroni test. Results: Results revealed that integrative acceptance and commitment-cognitive behavioral therapy reduces depression by 29% and anxiety by 11% in adolescent boys with sexual abuse (P<0. 01). The results also indicated that parental management training had no significant effect on reducing depression and anxiety in adolescent boys with sexual abuse (P>0. 05). Conclusion: The findings of this study showed that integrative acceptance and commitment-cognitive behavioral therapy is one of the treatments which is effective in reducing the depression and anxiety of adolescent boy with sexual abuse. This reduction in depression and anxiety will increase the mental health of these teenagers.

Introduction: The number of hemodialysis patients is increasing (not in Persian version). Due to the limitations of hemodialysis, these people need a caregiver and the caregivers of hemodialysis patients experience a great deal of caregiving burden which causes physical, mental and social problems for them. The aim of this study was to investigate the caregiving burden in the caregivers of hemodialysis patients in Kerman province and its relationship with some of their demographic variables. Materials and Methods: This descriptive-analytical study was performed on 382 hemodialysis caregivers in hemodialysis centers in Kerman, Sirjan, Rafsanjan, Jiroft and Kahnuj. Subjects were entered into the study through census and data were collected using the Novak Caregiving Questionnaire (24 questions) and analyzed by SPSS software version 20 and statistical tests, ttest, ANOVA, correlation coefficient and linear regression. Results: The results of this study indicated that 88. 2% of participants experience severe and moderate suffering. There was a statistically significant relationship between the mean score of Caregiver Burden with some patient demographic variables including: education level and employment status, patient income, patient's ability to perform personal tasks, dialysis frequency, patient's need for caregiver, renal transplant history, educational level, job status and the age of caregiver (P <0. 05). The results of linear regression analysis showed that variables of patient need for caregiver, patient dialysis frequency per week, patient income, and caregiver education were predictors of caregiver burden score which explained 32% of caregiver burden. Conclusion: Considering the high percentage of caregivers experiencing moderate to severe caregiver burden, it is recommended that caregivers of hemodialysis patients receive psychological and financial support.
