Abstract

Abstract Background and Objective: Diarrheal diseases may occur in all age groups, worldwide. Escherichia coli (E. coli O157: H7) is one of the most important bacterial agents causing this disease. The purpose of this study was to assess the prevalence of diarrhea in patients with acute diarrhea caused by this bacterium. Material and Methods: In this study, 214 stool samples were collected from acute diarrheic patients in hospitals and clinical laboratories of Malayer city, Iran. The samples were cultured in rich, differentiation, specific and selective medium. To detect E. coli O157: H7, rapid detection method and antisera were used . Results: In 12.15% of the samples, lactose fermentation was observed and E. coli was afirmed. The results of lactose positive samples showed that 6.54% were negative-β- Glucuronidases and were confirmed as E. coli O157. Finally, by using O157: H7 antisera, 1.87% of 14 samples that were negative- β-Glucuronidases were asserted as E. coli O157. Conclusion: based on the results, the prevalence of E. coli O157: H7 is higher in children and elders than the others. Food and water play a significant role in transferring E. coli.

Abstract

      Background and Objective: High-intensity interval training (HIIT) is a recently proposed exercise protocol, which is time-effective. The aim of this study was to evaluate the effect of HIIT for 8 weeks on the lipid profile, C-reactive protein (CRP), fasting blood sugar (FBS) and anthropometric parameters of young women who do not exercise.

     Methods: In this study, 20 young physically inactive women performed HIIT workouts for 8 weeks and 3 sessions per week. The training protocol consisted of 10-times treadmill running for 15 seconds at maximum effort and then 30 seconds of resting. Blood samples were taken while fasting, a day before and after the training and then the considered parameters were measured. Wilcoxon test was used to compare the obtained data.

      Results: HIIT significantly reduced FBS, cholesterol, low-density lipoprotein, high-density lipoprotein /cholesterol ratio and CRP while increasing the HDL levels. There was a significant difference in the weight, body fat percentage, waist circumference, abdominal circumference and chest circumference of the subjects before and after the training (p <0.05).

      Conclusion: HIIT can improve lipid, inflammatory and anthropometric parameters, thus it can be considered as a suitable alternative to time-consuming exercises, especially for physically inactive women who like to spend less time to achieve optimal physical wellness and body fitness.
