Background and objective: Damages to the oromaxillofacial region, if not diagnosed and treated in a timely manner, will cause permanent, serious clinical problems because of the characteristics of this anatomical region. Accordingly, the present study was performed on a 5-year investigation of epidemiology of oromaxillofacial fractures in patients admitted to Shahid Madani Hospital, Karaj, Iran.
Material And Methods: In this descriptive cross-sectional study, 235 medical files of patients with damages to the oromaxillofacial region available in the archive of Shahid Madani Hospital, Karaj from 2013 to 2018 were chosen as census and examined. Demographic variables including site and cause of fracture were recorded for each patient on information forms. The collected data were analyzed by SPSS 17 software and presented as descriptive statistics.
Results: In this study, out of 235 patients with oromaxillofacial fractures, 178 (75.7%) were male and 97 (41.3%) were female, respectively. The mean age of the patients was 30.96 ± 14.91 years. The main affected anatomical regions were as follows: Mandible 269 cases (49.17%), maxilla 117 cases (21.39%), and cheekbone 51 cases (9.32%). Accidents occuring with motor vehicles was the main cause of these fractures in 132 patients (56.2%).
Conclusion: The results of the present study indicated that the fractures of oromaxillofacial regions were more common in men, young people, and middle-aged individuals, and mostly occurred in the mandible, maxilla, and cheekbone, with the main cause of these fractures being accidents happening with motor vehicles.

Background and Objective: Musculoskeletal disorders are considered the primary health problem among military pilots. Thus, the aim of this study was to investigate the relationship between temperament, Somatotype and some anthropometric variables and prevalence of musculoskeletal injuries in military pilots.
Material and Methods: In this cross-sectional study which was conducted in 2020, in Tehran, 100 military pilots from selected Air Force bases were participated. Prediction of injury was assessed by functional movement screen test. The pilots’ temperaments were determined by the standard natural temperament questionnaire. Somatotype was calculated using the Heath-Carter method. Anthropometric data were also collected. The relationship between variables was evaluated by Pearson correlation coefficient and multiple linear regression and the difference between different temperaments in the values of variables was evaluated by one-way ANOVA (P < 0.05).
Results: The mean age, weight and functional movement screen score of the pilots were 34.36±5.94, 84.68±8.55 and 17.99±1.59, respectively. Between cold and wet temperament (P = 0.01), endomorphic component of somatotype (P = 0.001), weight (P = 0.001), Body mass index (P = 0.001), waist (P = 0.001), hip (P = 0.001), flexed arm (P = 0.004) and calf (P = 0.006) circumference had a significant negative relationship with functional movement screen test score. Functional movement screen test showed a significant positive relationship only with ectomorphic component (P = 0.001). There was no significant difference between different temperaments in functional movement screen test score (P = 0.64). Multiple linear regression showed a significant negative relationship only between functional movement screen test score and endomorphic component (P = 0.01).
Conclusion: According to the results, it can be concluded that cold and wet temperament, weight, body mass index and endomorphic component of somatotype as individual characteristics are important factors that inversely related to functional movement screen test score of military pilots that should be considered.

Background and Objective: Aging is the major risk factor for the development of cardiovascular diseases as aging increases plasma levels of pro-inflammatory mediators and endothelial dysfunction. Physical exercise and spirulina improve the endothelial dysfunction and chronic inflammation that accompanies aging. This study aimed to evaluate the effects of Aerobic Exercise (AT), with blue-algae Spirulina Supplementation (SP) on the indicators of endothelial dysfunction and insulin resistance in overweight adult men.
Material and Methods: In this clinical trial study, 40 overweight adult men (age 57.50±4.84 years, Body mass index: BMI 26.90±2.85 kg/m2) were selected from Bandar-e-Anzali and randomly allocated into five groups; including Control-Normal (CN), Overweight (OW), Overweight-Aerobic Training (OWAT), Overweight-Spirulina (OWSP) and Overweight-Aerobic Training -Spirulina (OWATSP). Training groups participated in an aerobic exercise program for eight weeks, five sessions per week (with an intensity of 65 to 85% of peak heart rate, 40 minutes). The OWSP and OWATSP groups were provided with two 500 mg SP tablets daily in the morning and evening. Data were analyzed using an independent t-test and ANCOVA at a significance level of
P <0.05.
Results: The levels of endothelin-1(ET-1), Intercellular Adhesion Molecule 1 (ICAM-1), Selectin-E, and HOMA-IR index in the OW group were higher than CN (P≤0.05). AT and SP significantly reduced ET-1, ICAM-1, Selectin-E, and HOMA-IR (P≤0.05). In the OWATSP group, the levels of ET-1, ICAM-1, Selectin-E, and HOMA-IR were significantly lower than OW and OWSP (P≤0.05). NO levels significantly decreased in OWATSP and OWAT (P≤0.05).
Conclusion: Aerobic training and spirulina supplementation could improve the endothelial function in overweight adult men, by altering the levels of ET-1, ICAM-1, Selectin-E, and NO. However, the simultaneous effect of AT with SP on these indices was better. Improved endothelial function was associated with an improvement in insulin resistance index.
