  Problem statement: Modern diets high in Saturated Fatty Acids (SFA) and low in Monounsaturated (MUFA) and Polyunsaturated (PUFA) fatty acids are mostly blamed for the increased incidence of cardiovascular diseases. Since dietary fatty acids are absorbed by monogastric animals and deposited in their tissues without significant modification, considerable potential exists for the manipulation of the fatty acid profile of poultry meat and eggs. In the present study, effects of different sources and levels of supplemental fat to low energy diets on energy and protein intake and efficiency during grower and finisher periods and cholesterol and Triglyceride (TG) contents of breast and thigh meat of broiler chicks were investigated. Approach: One hundred and eighty 1 day old Ross 308 broiler chicks of both sexes were used for 42 days. The chicks were randomly allocated to 15 pens containing 12 chicks each with 3 replicates and assigned to receive one of the 5 dietary treatments of 2 sources (soybean oil and beef tallow) and 2 levels of fat (20 and 40 g kg-1) in a completely randomized design with factorial arrangement. There was also a control treatment (without supplemental fat) in this experiment. All chicks were fed with a commercial starter diet from 1-10 day, where-after fed with isocaloric and isonitrogenous diets. Results: There were significant differences in energy and protein intake and energy and protein efficiency among treatments in all phases of the experiment (p<0.05). Energy and protein intake was significantly higher in the chicks fed with 40 g kg-1 soybean oil that compared to other groups. The effect of different sources and levels of supplemental fat on cholesterol and TG contents of thigh and breast meat of broiler chicks in 42 day of age was significant (p<0.05). Adding 20 g kg-1 soybean oil significantly decrease levels of cholesterol in thigh and breast meat (p<0.05). The highest TG value of breast meat was observed in control chicks compared with other groups (p<0.05). Conclusion: Supplementation of broiler diets with 20 g kg-1 soybean oil improved energy efficiency, decreased cholesterol content of breast and thigh meat of broiler chicks in comparison with other groups.

  This research was conducted to study the efficacy of different growth promotors on the productive performance and carcass yield of broiler chickens. About 840 sexed male ROSS 308 hybrid chickens were used according to completely randomized design in five treatments and one control. Thus, there were six group of chickens, 1) control diet (with out any promotors), 2) control diet + antibiotic, 3) control diet + probiotic, 4) control diet+prebiotic, 5) control diet+phytobiotic and 6) control diet+symbiotic. The productive indicators evaluated were: feed intake, weight gain, Feed Conversion Ratio (FCR). Also, it was determined the carcass yield and the main portions (breast, thigh and abdominal fat). In all over of current study, there wasn’t any significant difference between treatments in body weight gain but all of them had beneficial effect compare to control. Lowest feed conversion ratio was belong to probiotic group and cause more efficient feed intake. Treatments vs. control increased carcass yield significantly but the difference between treatments was not significant. Breast and thigh was not affected by treatments and there wasn’t any significant difference between treatments and control group. Lowest abdominal fat were seen in antibiotic group. According to the results probiotic and symbiotic appeared to be superior compare to other growth promotors. However, more studies are needed to confirm these findings and other aspects of growth promotors in the broiler diets.

  Fatty liver disease in non-alcoholic patients is among diseases causing changes in the body’s metabolism, especially lipid metabolism. Therefore, with changes in the metabolism of fatty liver, uric acid can be expected to rise in the body. This study was conducted to determine the relationship between levels of uric acid and the severity of non-alcoholic fatty liver disease in patients referred to Kermanshah University of Medical Sciences affiliated clinics in 2016. This study was a cross-sectional and analytical research. The subjects included all patients referred to clinics within the city of Kermanshah that their non-alcoholic fatty liver disease diagnosis and grade had been confirmed by ultrasound. By available sampling method, 215 subjects were selected. In a single laboratory, using the same assay kit their uric acid and other blood biochemical tests were evaluated and the resulted data were analyzed using SPSS Version 18. The results showed that the mean blood uric acid level of samples was equal to 6.44±1.55 mg dL–1. The mean values in men and women were as 6.95 and 5.88 mg dL–1, respectively that the difference was statistically significant (p<0.05). The mean value of blood uric acid of the samples would rise according to the non-alcoholic fatty liver grade. The ANOVA and Spearman ranking test showed no significant difference and relationship. The study results showed that high levels of uric acid in patients with fatty liver disease can be strong evidence on the severity of patients’ fatty liver. Therefore, to find out the situation and severity of fatty liver of patients they should be examined and followed up with more accurate methods like ultrasound, biopsy or advanced imaging methods.

  Nicorandil is a cardioprotective agent that improves anginal symptoms through dilatation of the coronary arteries as well as reduction of coronary vascular resistance. To assess the protective effects of short-term use of nicorandil on in-hospital outcome of patients with acute coronary syndrome. In a randomized double-blinded controlled trial, 240 patients suffered from typical chest pain and hospitalized with the final diagnosis of acute coronary syndrome infarction (NSTEMI) were included. The participants were randomly assigned to the intervention group receiving routine anti-thrombotic and anti-platelet drugs plus nicorandil 20 mg–1 bidorally 120 patients or control group receiving only routine cardiovascular drugs (120 patients). The severity of chest pain gradually reduced within 4 days of the study in both interventional and control groups but the decreasing trend in pain score was significantly more downward in former group. The prevalence rate of cardiac arrhythmias was 14.4% within a day after intervention that was significantly lower in intervention group than in control group (19.5 vs. 9.5%, p = 0.031). The occurrence rate of increase cardiac enzyme in the intervention and control groups was 9.9 and 29.7%, respectively with a significant difference (p<0.001). Also, the means level of cardiac enzymes including CK-MB and troponin T were initially lower in intervention group within the first day of assessment but remained similar in the next days. Regarding echocardiography indices, end-diastolic diameter was significantly lower in intervention group than in control group (47.4 vs. 49.7 mm, p = 0.034). Also, mitral insufficiency was significantly less prevalent in the former group (44.0 vs. 72.0%, p<0.001). No differences were observed in length of hospital stay or number of involved coronary arteries.

  Although, cesarean section has a higher rate of complications compared with vaginal delivery, there is a growing trend for cesarean section in Iran. This theory-based study was aimed to investigate the effect of an educational intervention on cesarean intention in nulliparous pregnant women. This study was a randomized controlled study. In total, 146 nulliparous pregnant women in the third trimester of pregnancy were recruited in different health centers in Kermanshah City in 2015. Before intervention, a baseline data collection was done by using a valid and reliable questionnaire on participants in both groups. In addition to routine prenatal care, the intervention group received the educational program designed on the constructs of the social cognitive and planned behavior theories. After 4 weaks of completing the educational program, data were collected in both groups. A SPSS Software version 21 was used for data analysis. Results showed that there were significant differences between the intervention and control groups after the educational intervention in terms of attitudes toward cesarean, outcome expectations, outcome expectancies, perceived behavior control, subjective norms and cesarean intention (p<0.05). The findings indicated that an intervention based on a combination of the constructs of the social cognitive and planned behavior theories can affect cesarean intention in women. Therefore, it seems that conducting such interventions, particularly in nulliparous pregnant women, can decrease cesarean intention.

  Women are likely to be involved in anxiety two times more than men. One of the reasons for this increase is that stressors like pregnancy and labor are specific for women. 70% of primigravidas and 75% of multigravidas experience anxiety during their pregnancy. So, this research was done with the aim of evaluating the effect of group discussion on the level of anxiety during pregnancy in primigravidas referred to Health and Medical Center in Khoram Abad city. The present study was done as a clinical trial on 60 primigavidas 20-25 weeks (30 subjects as intervention group 30 subjects as control group) referred to Health and Medical Center in Khoram Abad city. Data were collected using personal data form and Spiel Berger anxiety Inventory questionnaire. In addition to routine pregnancy care sixth 90 min sessions of group discussion courses were held during 6 weeks (once a week). The control group only received routine pregnancy care anxiety score before the intervention and at the end of the intervention were analyzed in all two groups. Data analysis was done using t-test, tabs analysis. In this study, the mean anxiety scores were not significantly different in the two groups before the intervention but there were significant differences in discussion group after the intervention (p<0/001). There was a decrease in the mean anxiety score in discussion group after the intervention whereas there was a slightly increase in the control group. The results of this study indicated that group discussion could reduce anxiety in primigravidas.

  Clinical competence can have an important effect on job satisfaction among nurses and other health care stuff. This study is a correlation study to determine the relationship between clinical competency and job satisfaction of nurses working in the critical care wards of Kermanshah. Data collection tools included demographic information, job satisfaction JDI and Benner questionnaire of nurse’s clinical competency that its reliability and validity had been confirmed. The questionnaires were distributed among all nurses working in the critical care wards that had conditions to be included in the study and after completing the questionnaires, 262 questionnaires can be evaluated that were analysed using SPSS, Version 18. The 55.3 and 42.4% of research units had high and moderate job satisfaction. Nonparametric tests only showed significance of difference of job satisfaction levels of research units with gender variables and place of their activity and score difference of clinical competence with work shift of research units (p<0.05). Overall, Spearma’s rank correlation coefficient showed a significant correlation between clinical competence and job satisfaction (p<0.05). The results of this study showed that the clinical competence of research units has a significant and direct correlation with their job satisfaction that with increased clinical competence their job satisfaction also increases and vice versa.
