Background:Futsal is a growing sport with lots of fans in many countries including Iran, but there are few papers in the literature which report injuries in top level futsal.Objectives:The aim of this study is to record and analyze the incidence and characteristics of injuries in Iran futsal national teams from March 2011 to September 2012.Patients and Methods:55 Iranian national futsal players participated in this prospective cohort study. Before entering the study, all players took part in Pre-Competition Medical Assessment (PCMA) in accordance with FIFA protocol. Team physicians recorded the injuries throughout the match and trainings in a special form which was designed for this purpose. Finally, data analysis was done with the SPSS software.Results:The total exposure time for all players was 24326 hours (21138 hours during training and 3188 hours during matches). During the study period, 32 of the 55 national players (58.2%) incurred 54 injuries (incidence rate = 2.22 injuries per 1000 players-hours). The incidence rate of injury in female players was significantly higher than male players (P = 0.001). The majority of injuries (85.2%) were located on the lower extremities. The ankle was the most frequent injury location (40.7%) and sprain was the most frequent type of injury.Conclusions:Injuries are common among futsal players and female players are more prone to injuries than male players. The ankle is the most frequent site and sprain is the most frequent type of injury among futsal players.

Several studies have shown that exercise is directly related to creating negative energy balance and changes in appetite. However, few studies have examined the effect of exercise time during the day on these factors. The aim of the present study was to demonstrate the effect of 6 weeks of morning and evening aerobic exercise on appetite and anthropometric indices. A total of 48 overweight females were recruited to this clinical trial. By the time of exercise, they were divided into two groups (morning or evening) and performed 6 weeks of exercise with a target heart rate on the ventilatory threshold. Appetite change, calorie intake and anthropometric indices were assessed. Consistent changes in appetite scores were not found during the 6 weeks (P > 0.05). Calorie consumption of the morning group decreased significantly more than that of the evening group (P = 0.02) during the 6 weeks. In addition, significant changes in body weight, body mass index, abdominal skin fold thickness and abdominal circumference were seen in the morning group. It appears that moderate- to high-intensity aerobic exercise in the morning could be considered a more effective programme than evening exercise on appetite control, calorie intake and weight loss in inactive overweight women. However, the limitations of the study, such as short-term duration, should be noticed.

Background:Increased reactive oxygen species (ROS) and lipid peroxidation are seen in many dermatologic disorders, for example, atopic dermatitis, psoriasis, vitiligo, acne vulgaris, pemphigus vulgaris (PV), lichen planus, and alopecia areata. ROS has an important role in the inflammation process. In PV, increased production of ROS leads to decline of antioxidants in plasma and red blood cells which results in oxidative stress. We aimed to evaluate the level of these antioxidants in PV patients and compare it to the controls.Materials and Methods:Among patients attending the dermatology clinics, 30 patients with PV, who had never been on treatment, were enrolled to the study. The control group consisted of 30 age- and sex-matched healthy non-smoker individuals. Venous blood was collected from the subjects for the evaluation of plasma levels of glutathione peroxidase, vitamin C, selenium, bilirubin, and uric acid.Results:Age mean and standard deviation of the patients (40.83, 12.74) was comparable to the controls (41.96, 13.08). Mean level of uric acid was significantly lower in PV patients compared to the controls (P = 0.006). Other antioxidants were not different between the two groups. Uric acid of the patients with mucosal involvement was significantly lower than patients with mucocutaneous involvement (P = 0.049).Limitations:The blood level of other antioxidants (e.g. malondialdehyde) was not evaluated.Conclusions:Uric acid as an antioxidant in our study had similar changes to previous studies in the field of other diseases but selenium, bilirubin, and glutathione peroxidase did not differ between patients and controls.
