Abstract
Background: Today, the high prevalence of diabetes and its complications are one of the most important public health issues worldwide. For this reason, finding relations between diabetes risk factors is very effective in preventing and reducing complications. For discovering these relations, the data mining methods can be used. By extracting association rules, which is one of the data mining techniques, we can discover the relations between a large numbers of variables in a disease.
Materials and Methods: The population of this study was 1046 patients with type 2 diabetes, whose data had recorded between 2011 and 2014 at the Special Clinic for Diabetes in Tehran's Imam Khomeini Hospital. After pre-processing step with SPSS19 software, 573 people entered the analysis phase. The FP-Growth algorithm was applied to the data set to discover the relations between heart attack and other risk factors using Rapid miner5 software. Relations, after extraction, were given to the doctor to confirm clinical validation.
Results: The obtained results of studying these 573 people (Including 292 (51%) women and 281 (49%) men, with age range 27 to 82 years) showed that the lack of blood pressure, creatinine and diastolic blood pressure at its normal level, despite higher systolic blood pressure level than normal, doesn't increase the probability of heart attack.
Conclusion: Using association rules is a good way of identifying relations between the risk factors of a disease. Also, it can provide new hypotheses to do epidemiological studies for researchers.

Abstract
Background and Aim: Exercise aerobic is associated with increased creatine kinase and blood lactate immediately after exercise, leading to increased muscle damage and undesirable changes in many cellular markers including serum creatine kinase. In such situations, consuming nutrients and supplements such as coenzyme Q10 may prevent metabolic stress damage by increasing buffering power. However, comprehensive studies have not been performed on the effects of this nutrient on the index of muscle injury and fatigue caused by exercise.
Methods & Materials: For this purpose, 20 inactive volunteer men were randomly divided into two groups of 10-person Coenzyme Q10 supplement (2.5 mg/kg body weight) and quasi-drug (2.5 mg/kg body weight Dextrose). All subjects participated in the Bruce test exercise contract after 14 days of supplementation. Blood sampling was performed in four stages including baseline, after supplementation, immediately after exercise and two hours after exercise. Creatine kinase, lactate and cortisol indices of both groups were measured during these four stages. Data were analyzed by means of standard deviation and repeated measures ANOVA, Bonferroni post hoc and Independent T-test using SPSS V. 17 at the significant level of 0.05.
Ethical Considerations: This article has been approved by the ethics committee of Tabriz School of Medical Sciences with the ethics code IRCT 201203104663N8.
Results: The results showed that 14 days of Coenzyme Q10 supplementation had a significant effect on cortisol level (P<0.05). In addition, one session of exhausting aerobic activity increased creatinine kinase and lactate (P<0.05). On the other hand, creatinine kinase did not differ significantly after exercise (P>0.05).
Conclusion: According to the results of the present study, 14-day supplementation of Coenzyme Q10 may reduce the cellular damage induced by exhaustive aerobic activity in inactive men and prevent an increase in blood lactate levels.

Abstract
Background and Aim: Obesity is a clinical condition that affects the growth-related hormonal system, especially in adolescents. High-Intensity Intermittent Training (HIIT) might reduce such destructive effects.
Methods & Materials: In this quasi-experimental research, among adolescent boys [age: 13-18 years, height: 154±8 cm, Body Mass Index (BMI): 27.05±1.4 kg/m²], 30 volunteer subjects were selected. The study participants were divided into 3 groups of short-term and long-term periodic exercises as well as controls. The short-term exercise group performed 9 bouts of 30 seconds with 150-second breaks between sessions; the long-term exercise group performed 4 bouts of 150 seconds with 240-second breaks between sessions 3 times a week for 8 weeks. Body composition and blood samples were obtained 48 hours before and after conducting the training protocol to measure the desired parameters. The changes of each index were analyzed by repeated-measures Analysis of Variance (ANOVA) at the significant level of P<0.05.
Ethical Considerations: This study was approved by the Ethics Committee of Tabriz University (Code: IR.TABRIZU.REC.1398.021).
Results: After 8 weeks of HIIT, growth hormone increased and thigh, arm circumference, and fat percentages decreased (P<0.05). However, no changes were detected in the insulin-like growth factor I, BMI, and weight of the examined subjects (P>0.05).
Conclusion: Short- and long-term HIIT have the potential to improve the growth hormone status and body composition of overweight adolescents.

Abstract
Introduction: Considering the importance of urinary tract infections caused by uropathogenic Escherichia coli (UPEC) in the medical field, this study aimed to investigate serogroups O25 and O16 and the pattern of antibiotic resistance among UPEC isolates obtained from hospitalized patients with urinary tract infections (UTIs) in Rasht hospitals.
Methods: A total of 110 urine samples were collected from patients with UTIs referred to selected hospitals in Rasht. The disk diffusion method, as recommended by the CLSI, was used to determine the pattern of antibiotic susceptibility. Serogroups O25 and O16 were detected using specific primers.
Results: Among the studied samples, 36.4% (40/110) were men and 63.6% (70/110) were women. Based on the antibiotic susceptibility pattern, a high level of antibiotic resistance was observed against nalidixic acid (81.8%) and co-trimoxazole (78.2%), while the most effective antibiotics were amikacin (85.5%) and nitrofurantoin (83.6%). In addition, multi-drug resistant phenotype was found in 72.7% (110/80) of UPEC isolates. According to PCR results, the frequency of serogroups O25 and O16 was 36.4% and 17.3%, respectively. Both serogroups had the highest resistance to nalidixic acid and co-trimoxazole, while the lowest resistance in serogroup O25 to nitrofurantoin (20%) and amikacin (14.3%) and in serogroup O16 to imipenem (5.3%) and nitrofurantoin (10.5%).
Conclusions: This study showed that the high prevalence of MDR strains among UPEC strains is very worrying and professionals should be very careful in prescribing antibiotics for patients. Like most studies, the frequency of serogroup O25 was high, and probably, this serogroup can play a role in causing urinary tract infections and antibiotic resistance of UPEC strains.
