Background and Objective: Asthma is the most prevalent chronic disease during childhood and it is estimated that 4.8 million children involved in asthma all over the world and its prevalence and incidence is increasing. The aim of this study was to identify the peak-flow meter application on quality of life in asthmatic children. Materials and Methods: This clinical trial study was done on 80 asthmatic children between 7 to 15 years old which referred to Shahid Beheshti hospital clinic in Kashan, Iran during 2009. Susan Sylvia questionnaire included 3 parts, was filled for every child. The questions in any section had three options in which there were 5 items in activity limitation, 13 questions in symptoms and 6 questions in emotional functions. Every question had 1 to 3 points and whole questionnaire taken 23 to 69 points. The children were learnt to measure their PEFR (Peak Expiratory Flow Rate) 3 times a day using Peak flow meter device and upon the results, the management procedure was changed. After 3 months the outcome were evaluated and data analyzed by SPSS-15 and paired t-test. Results: Mean age of patients was 8.82±2.75 years old. Thirty three subjects (41.3%) were girl. The average score in emotional functions was 13.1±3.07 before and 14.35±3.7 after using peak-flow meter (P<0.05). The average score in activity limitation was 7.33±1.57 and 8.47±0.67 before and after using peak-flow meter, respectively (P<0.05). The average score in symptoms before and after pek-flow meter was 28.81±5.13 and 32.02±5.62, respectively (P<0.05). Finally total score of quality of life showed significant increase in children after using peak-flow meter (P<0.05). Conclusion: This study showed that the application of pek-flow meter increase emotional functions, decrease limitation of activity and symptoms in asthmatic children.

Background and Objective: Type 2 diabetes is a chronic disease that associated with increased serum glucose and insulin function impairment. Exercise training and saffron supplement are known as two effective factors in the prevention of the complications of type 2 diabetes. The present study aimed to evaluate the impact of eight weeks of aerobic and resistance training with the consumption of saffron aqueous extract on malondialdehyde and glutathione peroxidase in men with type 2 diabetes.
Methods: In this clinical trial study, 36 men suffering from type 2 diabetes were randomly assigned into six groups: placebo, aerobic training, aerobic training with supplement consumption, resistance training, and resistance training with supplement consumption. Aerobic training was performed at 50-70% of maximal heart rate, and the resistance training was performed at 65-70% of the maximum replication for eight weeks. The saffron supplement was consumed at the dosage of 3 mg day-1. The concentration of malondialdehyde and glutathione peroxidase was measured before and after the trial after the 12-hour fasting period.
Results: Level of malondialdehyde significantly reduced in placebo and aerobic training with supplement prior to intervention (P<0.05). Level of glutathione peroxidase were significantly increased in aerobic training with supplement (P<0.05), resistance training (P<0.05) and resistance training with supplement (P<0.05) groups after intervention.
Conclusion: Aerobic and resistance training and their supplementation with saffron consumption can be regarded as an effective method to improve the peroxidase and antioxidant balance.

Background and Objective: Schizophrenia is a chronic disease associated with considerable impairments to personal life and social functions. Since exercise plays an important role in these problems, this study was done to compare the effect of high-intensity interval training (HIIT) and futsal training on body composition, physical fitness, life quality, and negative symptoms in schizophrenics.
Methods: This clinical trial was performed on 42 male patients with paranoid schizophrenia in Rasht Medical Center in north of Iran during 2017. Patients were randomly assigned into three groups of HIIT (n=15), futsal (n=12) and control (n=15) groups. Data were collected before and after 8 weeks of training using quality of life questionnaire, negative symptoms assessment and some factors of physical fitness tests. HIIT program (high-intensity interval training: HIIT) was held three sessions a week with 70 to 85% of maximal heart rate and futsal training lasted three sessions a week for 40 minutes.
Results: Anaerobic power was significantly more in HIIT and futsal groups in compatre to controls (P<0.05), but anaerobic power was not significantly different between HIIT and futsal groups. Lower limb muscle power was significantly higher in the HIIT and futsal groups compared to control group (P<0.05). Lower limb muscle power was higher in the HIIT group compared to the futsal group (P<0.05). Negative symptoms were significantly lower in HIIT and futsal groups in comparison with control group (P<0.05). The quality of life difference in futsal and HIIT groups was not significant in compared to the controls.
Conclusion: It seems that HIIT is more efficient than futsal exercises, but both types of training improve some factors of physical fitness and alleviate the negative symptoms among schizophrenics.

Background and Objective: Physical disability caused by multiple sclerosis (MS) increases MS patients' need for support from others. Medication adherence is one of the main success factors in the treatment of chronic diseases, which is influenced by various factors. This study aimed to determine the relationship between perceived social support and medication adherence in patients with MS.
Methods: This descriptive-analytical study was conducted on 110 patients (70 women and 40 men) aged 39±9 years with MS who visited the 2 medical training centers of Isfahan University of Medical Sciences (Kashani and Al-Zahra), Isfahan, Iran during 2021. After sampling by the systematic random method, the data were collected by interviews and using Zimmet's Perceived Social Support Scale (MSPSS) and the Morisky Medication Adherence Scale (MMAS-8).
Results: The mean and standard deviation of the scores of medication adherence and perceived social support were 6.10±1.72 and 62.83±14.97, respectively. According to the Pearson correlation coefficient, perceived social support did not show any significant relationship with medication adherence (r=0.185, P=0.053). Perceived social support showed a statistically significant relationship with income satisfaction (F=4.54, P=0.01), the pattern of clinical course (F=2.95, P=0.03), difficulty in accessing medical care (t=-2.29, P=0.02), and clinical symptoms, including motor (t=-3.72, P=0.001), balance (t=-3.23, P=0.002), and urinary disorders (t=-2.53, P=0.01).
Conclusion: Perceived social support in patients with MS did not cause medication adherence.
