This study aimed at investigating the impact of an educational intervention based on transtheoretical model to increase physical activity and improve metabolic syndrome indicators in women.
In this quasi-experimental study, 142 women with metabolic syndrome were randomly assigned to the case and control group (each group 71 participants). SECQ (Marcus), processes of change (Marcus), decisional balance (Bandura) and self-efficacy (Nigg) questionnaires and International Physical Activities Standard Questionnaire in preintervention, 3 and 6 months after intervention were completed. Furthermore, abdominal obesity, triglycerides (TG), and high-density lipoprotein (HDL) were measured. Physical activity intervention based on transtheoretical model (TTM) was performed in the case group. Finally, data were analyzed by SPSS (16) (SPSS Inc., Chicago, IL, USA) and repeated measure ANOVA, independent t-test and Freidman was used. A two-tailed P value, lower than 0.05, was considered to be statistically significant.
After the intervention, physical activity level increased in the intervention group, and they also progressed in stages of change, but the people in the control group had regressed. All changes in TTM constructs were significant in the intervention group during the time and differences in pros and cons were not significant in the control group. Abdominal obesity and TG has significantly reduced, and HDL has increased in the intervention group. In the control group, there was a significant increase in TGs and a decrease in HDL.
Physical activity training based on TTM can improve physical activity and metabolic syndrome indicators in women.

Depending on the site of irradiation, about 40-80% of patients undergoing radiotherapy (RT) will experience nausea and/or vomiting. The current study aimed to investigate the efficacy of ondansetronas as a single agent and with a combination to aprepitant on preventing RT-induced nausea and vomiting (RINV).
Materials and Methods:
In a clinical randomized controlled trial (from September 2010 to September 2011), conducted in Radiation Oncology Department of Seyed-al-Shohada Hospital, Isfahan University of Medical Sciences, 40 abdominopelvic malignancies cancer patients were allocated into two aliquots using block randomization of size. Patients in the first group (group I) received ondansetron alone while those patients in the remaining group (group II) received ondansetron and aprepitant. Then, developing of RINV and its severity and benefit of adding aprepitant to ondansetron, in comparison with ondansetron as a single drug therapy were evaluated.
The average age of the patients in group I was 61.15 ± 12.27 years while in group II it was 50.1 ± 13.27 years. No statistically significant gender differences were found between the two groups. In patients treated with ondansetron single drug therapy (group I), frequency and grade of RINV were significantly more than the group treated simultaneously by aprepitant and ondansetron (group II) (odds ratio [OR] = 21.2; P < 0.01). Compared with RT alone, the patients whom underwent RT along with chemotherapy showed lower probability of experiencing RINV (OR = 0.13; P < 0.05).
The present study indicated a significant superiority of combination of ondansetron and aprepitant in management of RINV, in patients undergoing RT, compared to ondansetron as a single agent therapy. More accurate follow-up studies are needed for the evaluation of the efficacy of ondansetron with combination to aprepitant on preventing the RINV.

Some personality traits and coping styles could be as risk factors in stressful situations. This study aimed to investigate the association of personality traits and coping styles according to the stress level.
Meterials and Methods:
This cross-sectional study was performed in 2011. A total of 4628 individuals over 20 years were selected by random sampling from nonacademic employees that working in 50 different centers across Isfahan province. Data were collected using 12-item General Health Questionnaire (GHQ-12), Big Five Personality Inventory Short Form and coping strategies scale, and individuals were divided into high and low-stress groups in term of GHQ-12. To analyze the data, a binary logistic regression analysis was conducted.
Mean age of participants was 36.3 ± 7.91 years and 56.26% (2604) of them were female. Neuroticism with adjusting covariates of demographic characteristics and the rest of personality traits was a risk factor for stress level with odds ratios (OR) OR:1.24; but other personality traits were protective. Also, active coping styles were protective factors for OR of stress level with adjusting covariates of demographic characteristics and the rest of coping styles, and positive reinterpretation and growth was the most effective of coping style with OR:0.84.
Some personality traits are associated with passive copings and cause high-stress level. So, it could be concluded that improve and strengthen effective coping strategies in individual with maladaptive traits should be considered as a crucial component of prevention and control programs of stress.

Polycystic ovary syndrome (PCOS) is a polygenic endocrine disorder in women of reproductive age that lead to infertility. The aim of this study was to investigate the effects of probiotic on pancreatic β-cell function and C-reactive protein (CRP) in PCOS patients.
This randomized double-blind placebo-controlled clinical trial was conducted among 72 women aged 15–40 years old diagnosed with PCOS. Participants were randomly assigned to two groups receiving: (1) Probiotic supplements (n = 36), (2) placebo (n = 36) for 8-week. Fasting blood samples were taken at baseline and after 8-week of intervention.
Probiotic supplementation, compare with placebo, reduced fasting blood sugar (−4.15 ± 2.87 vs. 2.57 ± 5.66 mg/dL, respectively P = 0.7), serum insulin levels in crude model (−0.49 ± 0.67 vs. 0.34 ± 0.82 μIU/mL, respectively, P = 0.09), homeostasis model of assessment-insulin resistance score (−0.25 ± 0.18 vs. −0.05 ± 0.18, respectively, P = 0.14) nonsignificantly. Serum insulin levels after adjustment with covariates reduced significantly in probiotic group (P = 0.02). We did not found any significant differences in mean changes of CRP between groups (−0.25 ± 0.18 vs. −0.05 ± 0.18, respectively, P = 0.14).
A 8-week multispecies probiotics supplementation had nonsignificantly beneficial effect on pancreatic β-cell function and CRP in PCOS patients. After adjustment for some covariates, serum insulin changes were significantly different between groups.

Objectives. In current study, the relationships between serum vitamin D3 levels and serum UA concentrations as well as their interaction with severity of PD were evaluated in a sample of Iranian PD patients. Method. In a cross sectional study at the one of the main referral hospitals in central region of Iran, during September to November 2011, 112 patients were recruited. Severity of PD was evaluated sing H&R stages and UPDRS. Results. The Spearman rank correlation coefficient suggests the negative significant association between serum vitamin D3 and UPDRS in patients aged >62 (r = −0.34, P < 0.05). No statistically significant association was observed between the UA levels and severity of PD (represented by H&Y categories) in different levels of serum vitamin D3 not only in total sample but also in separate age and sex groups. The linear regression coefficients suggested positive association between UA and serum vitamin D3 with UPDRSIII scores while negative relationship between UA and serum vitamin D3 interaction with UPDRSIII; however it was only statistically significant in age group ≤62 (P < 0.05). Conclusion. Our study revealed a negative correlation between interaction of serum vitamin D3 and UA with severity of PD; other studies are required to confirm our findings.
The objective of this clinical trial was to assess the effects of probiotic soy milk and soy milk on anthropometric measures and blood pressure (BP) in type 2 diabetic (T2D) patients.
A total of 40 patients with T2D, 35-68 years old, were assigned to two groups in this randomized, double-blind, controlled clinical trial. The patients in the intervention group consumed 200 ml/day of probiotic soy milk containing Lactobacillus planetarium A7 and those in control group consumed 200 ml/day of soy milk for 8 weeks. Anthropometric and BP measurements were performed according to standard protocols. For detecting within-group differences paired-sample t-tests was used and analysis of covariance was used for determining any differences between two groups. (The trial has been registered in the Iranian Registry of Clinical Trials, identifier: IRCT: IRCT201405265062N8).
In this study, we failed to find any significant changes between probiotic soy milk and soy milk in term of body mass index (26.65 ± 0.68 vs. 26.33 ± 0.74, P = 0.300) and waist to hip ratio (1.49 ± 0.08 vs. 1.54 ± 0.1, P = 0.170). Although soy milk did not have any effect on BP, probiotic soymilk significantly decreased systolic (14.7 ± 0.48 vs. 13.05 ± 0.16, P = 0.001) and diastolic BP (10 ± 0.7 vs. 9.1 ± 1, P = 0.031).
In our study, probiotic soy milk in comparing with soy milk did not have any beneficial effects on anthropometric measures in these patients. We need more clinical trial for confirming the effect of probiotic foods on anthropometric measure in diabetic patients. However, probiotic soy milk decreased systolic and diastolic BP significantly.

The present study was designed to evaluate hypertension and dyslipidemia in prediabetic subjects with a family history of type 2 diabetes (first-degree relatives), and they were compared with the normal glucose-tolerance subjects.
Materials and Methods:
Three thousand and eighty-six (788 men and 2298 women) subjects were selected from a consecutive sample of patients with Impaired Glucose Tolerance (IGT), Impaired Fasting Glucose (IFG), and Combined (IFG and IGT), and their first-degree relatives formed the control group. Potential risk factors for diabetes including age, gender, body size, HbA1c, cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, blood pressure (BP), urine microalbumin, and family and personal medical history were assessed.
The studied participants included 300 IGT patients (9.7%), 625 IFG patients (44.9%), 411 combined patients (13.3%), and 1750 (56.7%) normal subjects. Aging led to increase in hypertension. Increase in body mass index (BMI) led to an increase in the prevalence of hypertension significantly in all groups. The mean triglyceride in the normal group was different in comparison with that of the IGT (P < 0.05) and combined (P < 0.001) groups. Differences in total cholesterol were observed in the normal group when compared with the IGT (P < 0.05) and combined (P < 0.001) groups, and of the combined group in comparison with the IGT (P < 0.05) group. The difference in LDL level was related to the combined group in comparison with IGT, marginally (P < 0.1), and normal in comparison with the combined group (P < 0.05).
Prevalence of hypertension was not significantly different between the groups, however, in prediabetic patients it was higher than in the normal group, and prevalence of dyslipidemia in prediabetic subjects was significantly higher than in the normal group.

We aimed to evaluate the effects of Pimpinella anisum (anise) from Apiaceae family on relieving the symptoms of postprandial distress syndrome (PDS) in this double-blind randomized clinical trial.
Materials and Methods:
Totally, 107 patients attending the gastroenterology clinic, aged 18-65 years, diagnosed with PDS according to ROME III criteria and signed a written consent form were enrolled. They were randomized to receive either anise or placebo, blindly, for 4 weeks. Anise group included 47 patients and received anise powders, 3 g after each meal (3 times/day). Control group involved 60 patients and received placebo powders (corn starch), 3 gafter each meal (3 times/day). The severity of Functional dyspepsia (FD) symptoms was assessed by FD severity scale. Assessments were done at baseline and by the end of weeks 2, 4 and 12. Mean scores of severity of FD symptoms and the frequency distribution of patients across the study period were compared.
The age, sex, body mass index, smoking history, and coffee drinking pattern of the intervention and control groups were not significantly different. Mean (standard deviation) total scores of FD severity scale before intervention in the anise and control groups were 10.6 (4.1) and 10.96 (4.1), respectively (P = 0.6). They were 7.04 (4.1) and 12.30 (4.3) by week 2, respectively (P = 0.0001), 2.44 (4.2) and 13.05 (5.2) by week 4, respectively (P = 0.0001), and 1.08 (3.8) and 13.30 (6.2) by week 12, respectively (P = 0.0001).
This study showed the effectiveness of anise in relieving the symptoms of postpartum depression. The findings were consistent across the study period at weeks 2, 4 and 12.

We aimed to assess the effects of anise on quality of life (QOL) of patients with functional dyspepsia (FD) in a double-blind randomized clinical trial.
Materials and Methods:
Of 180 patients attending the gastroenterology clinic, 107 ones with the diagnosis of postprandial distress syndrome according to Rome III criteria were enrolled. They were randomized into two groups, anise and placebo. Anise group involved 47 patients and received anise powders, 3 g after each meal (3 times/day) for 4 weeks. Control group had 60 patients who received placebo powders (cornstarch), 3 g after each meal (3 times/day) for 4 weeks. The QOL was assessed by short-form (SF)-36 questionnaire. Mean scores of eight health domains of the two groups were compared at baseline and at the end of study.
The age, sex, body mass index, smoking history, tea and coffee drinking patterns of the two groups were not significantly different. All domains of SF-36 were similar between the two groups at baseline but were significantly different at week 12. At baseline, mean score of physical component summary was 159 in placebo group and 167 in anise group (P = 0.1). At week 12, the score was 141 in placebo group and 251 in anise group (P = 0.0001). Mean baseline score of mental component summary was 172 and 165 in placebo and anise groups, respectively (P = 0.1). At week 12, the score was 135 in placebo group and 233 in anise group (P = 0.0001).
The current study revealed the effectiveness of anise in improvement of QOL in patients with FD.

Neonatal respiratory distress syndrome (RDS) in premature infants who survived and its complications are a common problem. Due to high morbidity and mechanical ventilation (MV) nowadays researchers in interested minimizing MV. To determine, in very low birth weight (BW) preterm neonates with RDS, if initial treatment with nasal intermittent mandatory ventilation (early NIMV) compared with early nasal continuous positive airway pressure (early NCPAP) obtains more favorable outcomes in terms of the duration of treatment, and the need for endotracheal tube ventilation.
In this single-center randomized control trial study, infants (BW ≤ 1500 g and/or gestational age ≤ 34 weeks) with respiratory distress were considered eligible. Forty-four infants were randomly assigned to receive early-NIMV and 54 comparable infants to early-NCPAP. Surfactants were given, when FIO2 requirement was of >30%. Primary outcomes were failure of noninvasive respiratory support, that is, the need for MV in the first 48 h of life and for the duration of noninvasive respiratory support in each group.
98 infants were enrolled (44 in the NIMV and 54 in the NCPAP group). The Preventive power of MV of NIMV usage (95.5%) was not lower than the NCPAP (98.1%) strength (hazard ratio: 0.21 (95% confidence interval: 0.02-2.66); P: 0.23). The duration of noninvasive respiratory support in the NIMV group was significantly shorter than NCPAP (the median (range) was 24 (18.00-48.00) h versus 48.00 (22.00-120.00) h in NIMV versus NCPAP groups; P < 0.001). Similarly, the duration of dependency on oxygen was less, for NIMV (the median (range) was 96.00 (41.00-504.00) h versus144.00 (70.00-1130.00) h in NIMV versus NCPAP groups; P: 0.009). Interestingly, time to full enteral feeds and length of hospital stay were more favorable in the NIMV versus the NCPAP group.
Initial treatment of RDS with NIMV was safe, and well tolerated. Furthermore, NIMV had excellent benefits such as reduction of the duration of treatment, oxygen dependency period and length of hospital stay. Therefore, the primary mode with NIMV could be a feasible method of noninvasive ventilation in very premature infants.

The impact of honey or vinegar on several metabolic abnormalities has been studied separately, a mixture of these two ingredients known as honey vinegar syrup (HVS) has not been investigated previously so far. The aim of this study was to assess the impact of HVS consumption (Iranian's traditional syrup) on glycemic parameters and lipid profiles in healthy individuals.
We conducted a 4-week, randomized, controlled, parallel study consisting of two groups of nonobese healthy volunteers. All subjects were asked to stay on their normal diet. Intervention group (n = 36) received a cup of HVS daily in the evening snack for 4-week (250 cc syrup contains 21.66 g honey vinegar). Assessments of fasting blood sugar (FBS), insulin, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were conducted at the baseline and after 4-week of study.
We observed no significant effect of HVS on FBS, HOMA-IR, LDL-C and TG. A significant effect of HVS was found on increasing fasting insulin and HOMA-IR and reduction in TC level only in intervention group (Δ =3.39 P = 0.01, Δ =1.65 P = 0.03, Δ = −9.43 P = 0.005, respectively). Changes of FBS, TG and LDL-C were 1.83 mg/dl, −1.53 mg/dl and − 3.99 mg/dl respectively in the intervention group. These changes were not significant. An unfavorable and significant reduction in HDL-C level was also observed between two groups (Δ = −4.82 P < 0.001 in the intervention group).
Honey vinegar syrup increased fasting insulin level and decreased TC level in the intervention group. HVS had an unfavorable effect on HDL-C level. Further prospective investigations are warranted to confirm these findings.

Necrotizing enterocolitis (NEC) is one of the most destructive diseases associated with conditions of neonatal prematurity. Supplementation with enteral prebiotics may reduce the incidence of NEC, especially in infants who fed exclusively with breast-milk. Therefore, we compared the efficacy and safety of enteral supplementation of a prebiotic mixture (short chain galacto-oligosaccharides/long chain fructo-oligosaccharides [SCGOS/LCFOS]) versus no intervention on incidence of NEC in preterm infants.
In a single-center randomized control trial 75 preterm infants (birth weight [BW] ≤1500 g, gestational age ≤34 weeks and were not fed with formula) on 30 ml/kg/day volume of breast-milk were randomly allocated to have enteral supplementation with a prebiotic mixture (SCGOS/LCFOS; 9:1) or not receive any prebiotic. The incidence of suspected NEC, feeding intolerance, time to full enteral feeds, duration of hospitalization were investigated.
Differences in demographic characteristics were not statistically important. SCGOS/LCFOS mixture significantly reduced the incidence of suspected NEC, (1 [4.0%] vs. 11 [22.0%]; hazard ratio: 0.49 [95% confidence interval: 0.29-0.84]; P = 0.002), and time to full enteral feeds (11 [7-21] vs. 14 [8-36] days; P - 0.02]. Also duration of hospitalization was meaningfully shorter in the prebiotic group (16 [9-45] vs. 25 [11-80]; P - 0.004]. Prebiotic oligosaccharides were well tolerated by very low BW (VLBW) infants.
Enteral supplementation with prebiotic significantly reduced the incidence of NEC in VLBW infants who were fed exclusively breast-milk. This finding suggests that it might have been the complete removal of formula which caused a synergistic effect between nonhuman neutral oligosaccharides (prebiotic) and human oligosaccharides.

Appetite lowering characteristics of dairy have attracted scientists to look for its effect on energy intake particularly among children. In the present study, we tried to assess the effect of low-fat milk on total and short-term energy intake among obese boys in a randomized three-way cross-over clinical trial.
A total of 34 obese 10-12-year-old boys were randomized to consume three beverages (low-fat milk, apple juice, or water) with a fixed energy breakfast for two consecutive days, 1 week apart. Ad libitum lunch was provided for subjects 5 h later. The energy intake from breakfast till lunch and total energy intake on intervention days, and 2 days after intervention were compared. Generalized linear model repeated measures procedure in which test beverages were considered as repeated factors.
Energy intake from breakfast till lunch was lower when low-fat milk consumption was included in the breakfast compared with water and apple juice (adjusted mean ± standard error: Low-fat milk = 1484.33 ± 15.30 Kcal, apple juice = 1543.39 ± 20.70 Kcal, water = 1606.6 ± 19.94 Kcal; P < 0.05). The energy intake on a day before interventions, total energy intake on intervention days, and 2 days after intervention was not statistically different between intervention periods (P > 0.05).
One serving of low-fat milk might affect the energy intake in a short-term period. The possible effect of frequent consumption of dairy products on long-term energy intake among children is needed to be examined.

The people with prediabetes have insulin resistance (IR). IR may affect thyroid function, size and nodules. We investigated the effects of metformin on the thyroid gland in prediabetic people.
Materials and Methods:
In a randomized, double-blind placebo-control clinical trial, 89 people with prediabetes, aged 18-65 years were studied for 3 months. They were divided into two, metformin (n = 43) and placebo (n = 46) treated groups. Serum thyroid stimulating hormone (TSH) was measured and thyroid nodules and volume was studied by ultrasonography. The data were compared between and within groups, before and after the study.
Mean of the baseline characteristics in metformin and placebo-treated groups had no statistically significant difference. At the end of the study, serum TSH was not significantly different between the two groups. However, if the TSH range was divided into two low normal (0.3-2.5 μU/ml) and high-normal (2.6-5.5 μU/ml) ranges, significant decrease was observed in metformin-treated group with a high-normal basal serum TSH (P = 0.01). Thyroid volume did not change in metformin-treated group. However, in placebo-treated group, the thyroid was enlarged (P = 0.03). In 53.9% of participants, thyroid nodule was observed. There was just a decrease in the volume of small solid (not mixed) nodules from median of 0.07 ml to 0.04 ml in metformin-treated group (P = 0.01).
In prediabetic people, metformin decreases serum TSH, only, in those people with TSH >2.5 μU/ml and reduces the size of small solid thyroid nodules. It also prevents an increase in the thyroid volume.

Evidences have shown that migraine with aura (MA) is associated with elevated homocysteine levels but, few studies have evaluated the relationship between homocysteine levels and characteristics of migraine attacks such as severity, frequency, duration and headache diary result (HDR). Thus, in this study, we investigated the association between homocysteine levels and characteristics of migraine attacks in patients with MA.
Materials and Methods:
This cross-sectional study was carried out in Isfahan city, Iran, in February 2013. Fasting serum levels of homocysteine were measured in 130 MA patients (31 males and 99 females) aged 15-60 years. Severity, frequency and duration of migraine attacks, as well as HDR, were determined in each patient according to international headache society criteria by a neurologist. Linear and ordinal logistic regression tests were used to evaluate the relationship between serum homocysteine levels and characteristics of migraine attacks.
There is no significant association between serum levels of homocysteine with severity, frequency, duration and HDR. This association was not significant after adjustment of confounding variables such as age, body mass index (BMI) and family history of migraine. However, serum homocysteine levels were significantly associated with HDR among males after adjustment for age, BMI and family history of migraine (P = 0.01).
Significant relationship between homocysteine levels and characteristics of migraine attacks such as severity, frequency, duration and HDR were not found. However, after adjustment of confounding variables, we found a significant positive relationship between homocysteine levels and HDR among men.

Despite exercise is recommended as an adjunct to medication therapy in patients with heart failure (HF), non-adherence to exercise is a major problem. While improving self-efficacy is an effective way to increase physical activity, the evidence concerning the relationship between strategies to enhance self-efficacy and exercise among HF has not been systematically reviewed. The objective of this systematic review is to assess the effect of interventions to change the self-efficacy on exercise in patients with HF.
A systematic database search was conducted for articles reporting exercise self-efficacy interventions. Databases such as PubMed, ProQuest, CINAHL, Scopus, and PsycINFO, and the Cochrane Library were searched with restrictions to the years 2000-June 2014. A search of relevant databases identified 10 studies. Published randomized controlled intervention studies focusing strategies to change self-efﬁcacy to exercise adherence in HF were eligible for inclusion. In addition, studies that have applied self-efficacy-based interventions to improve exercise are discussed.
Limited published data exist evaluating the self-efficacy strategies to improve exercise in HF. Dominant strategies to improve patients’ self-efficacy were performance accomplishments, vicarious experience, verbal persuasion, emotional arousal.
Evidence from some trials supports the view that incorporating the theory of self-efficacy into the design of an exercise intervention is beneficial. Moreover, exercise interventions aimed at integrating the four strategies of exercise self-efficacy can have positive effects on confidence and the ability to initiate exercise and recover HF symptoms. Findings of this study suggest that a positive relationship exists between self-efficacy and initiating and maintaining exercise in HF, especially in the short-term period.

Prediabetes is a high-risk condition for type 2 diabetes mellitus. The growing prevalence of diabetes emphasizes on the necessity of concentrating on various strategies to prediabetes prevention and management. Probiotics as a group of functional foods might exert antidiabetic effects. This study aimed to assess the effects of probiotic administration on blood lipid profile and blood pressure in patients with prediabetes.
This randomized controlled trial consisted of 60 prediabetic patients, aged 25-65 years old, that were randomly assigned to the intervention (receiving 500 mg probiotic capsules, n = 30) or control group (receiving placebo, n = 30) for 8-week period. Demographic and anthropometric data were collected at baseline. Blood samples were collected at baseline and after 8 weeks for biochemical measurements. Blood pressure was measured at the baseline an after 8 weeks of intervention. Data regarding dietary intakes and physical activity were also collected during the study. We used SPSS software version 16 (SPSS Inc. Chicago, USA) for data analyzing.
Probiotic supplementation did not contribute to significant changes in total cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, Triglycerides (TG), TG/LDL and LDL/HDL ratios, after 8 weeks. After adjusting for potential confounders, HDL-cholesterol reduced significantly in the placebo group compared with probiotic group. Percent change in systolic blood pressure was significantly different in the probiotic group in comparison with a placebo group (–3.10 ± 2.22 vs. 3.24 ± 1.96, P = 0.01), although this significance did not exist anymore after adjusting for confounders (P > 0.05).
Our study showed that probiotics did not have significant effects on lipid markers although they had positive effects on systolic blood pressure.

Due to the excessive and pathologic effects of depression and anxiety, it is important to identify the role of protective factors, such as effective coping and social support. This study examined the associations between perceived social support and coping styles with depression and anxiety levels.
Materials and Methods:
This cross sectional study was part of the Study on the Epidemiology of Psychological, Alimentary Health and Nutrition project. A total 4658 individuals aged ≥20 years was selected by cluster random sampling. Subjects completed questionnaires, which were used to describe perceived social support, coping styles, depression and anxiety. t-test, Chi-square test, pearson's correlation and Logistic regression analysis were used in data analyses.
The results of Logistic regression analysis showed after adjusting demographic characteristics for odd ratio of anxiety, active copings such as positive re-interpretation and growth with odds ratios; 95% confidence interval: 0.82 (0.76, 0.89), problem engagement (0.92 [0.87, 0.97]), acceptance (0.82 [0.74, 0.92]) and also among perceived social supports, family (0.77 [0.71, 0.84]) and others (0.84 [0.76, 0.91]) were protective. In addition to, for odd ratio of depression, active copings such as positive re-interpretation and growth (0.74 [0.69, 0.79]), problem engagement (0.89 [0.86, 0.93]), and support seeking (0.96 [0.93, 0.99]) and all of social support types (family [0.75 (0.70, 0.80)], friends [0.90 (0.85, 0.95)] and others [0.80 (0.75, 0.86)]) were protective. Avoidance was risk factor for both of anxiety (1.19 [1.12, 1.27]) and depression (1.22 [1.16, 1.29]).
This study shows active coping styles and perceived social supports particularly positive re-interpretation and family social support are protective factors for depression and anxiety.

After cleft palate repair, oronasal fistula (ONF) formation is one of the considerable and troublesome complications. Conchal cartilage graft is one option that can be used in recurrent fistula correction. The aim of the current study is investigating the recurrence rate of the hard palate ONF or ONF at the junction of hard and soft palate after utilizing conchal cartilage graft and comparing this rate with other methods.
Materials and Methods:
In this observational prospective study, 29 patients suffering from ONF with small, medium and large sizes who were referring to Alzahra university hospital, Isfahan, Iran and Fateme Zahra university hospital, Tehran, Iran between November 2011 and November 2012 were enrolled. All patients had midline cleft palate, 29.6% of them had cleft lip too that was repaired previously. All patients were followed-up for 2 years (every 2 months) after repair.
The mean (range) age of studied samples was 10.7 (2-23) years. 16 patients (55.7%) were female, and reminders were male. During 2 years followup, we detected recurrence of ONF in 6 patients (20.68%) and the success rate was 79.32%. The recurrence rate, after applying the current approach, among who experienced the several times of recurrence was significantly higher than among those who experienced first time of recurrence (33.3% vs. 7.1%; P < 0.001). The mean [±SD] age of failed and successfully repaired patients were 11.3 (±4.5) and 8.4 (±5.25) years, respectively (P > 0.1).
Using of conchal cartilage graft for recurrent ONF with ≤1 cm was safe and efficacious, in ONF >1 cm conchal cartilage graft can be used as a primary method and if recurrence occurred chooses other complex procedure.

Background and Objective. Breast cancer (BC) continues to be a major cause of morbidity and mortality among women throughout the world and in Iran. Lack of awareness and early detection program in developing country is a main reason for escalating the mortality. The present research was conducted to assess the Iranian women's level of knowledge about breast cancer risk factors, early warning signs, and therapeutic and screening approaches, and their correlated determinants.
Methods. In a cross-sectional study, 2250 women before participating at a community based screening and public educational program in an institute of cancer research in Isfahan, Iran, in 2012 were investigated using a self-administered questionnaire about risk factors, early warning signs, and therapeutic and screening approaches of BC. Latent class regression as a comprehensive statistical method was used for evaluating the level of knowledge and its correlated determinants.
Results. Only 33.2%, 31.9%, 26.7%, and 35.8% of study participants had high awareness levels about screening approaches, risk factors, early warning signs and therapeutic modalities of breast cancer, respectively, and majority had poor to moderate knowledge levels. Most effective predictors of high level of awareness were higher educational qualifications, attending in screening and public educational programs, personal problem, and family history of BC, respectively.
Conclusion. Results of current study indicated that the levels of awareness among study population about key elements of BC are low. These findings reenforce the continuing need for more BC education through conducting public and professional programs that are intended to raise awareness among younger, single women and those with low educational attainments and without family history.
The prevalence of prediabetes in the world continues to increase. These patients have elevated the risk of atherosclerosis. The current study was designed to assess the prevalence of peripheral arterial disease (PAD) and its related risk factors in prediabetes patients.
This was the case-control study in which 135 adults in three groups: Diabetes, prediabetes, and normal were studied. We evaluated the prevalence of PAD through the measurement of ankle-brachial index (ABI). All the patients were interviewed about demographic and medical data, including age, sex, disease duration, body mass index, hypertension (HTN), fasting blood glucose, hemoglobin A1C (HbA1C), lipid profile, and medication use.
The prevalence of PAD in diabetes patients was higher than the normal group (8.5%vs. 0.0%) (P < 0.05), but the differences between prediabetes compared with diabetes and normal group were not significant. The mean level of ABI in normal, prediabetes, and diabetes group was (1.11 ± 0.11), (1.09 ± 0.12), and (1.05 ± 0.03) respectively (P < 0.1). There were marginally significant differences of ABI observed between the normal group and the diabetes group. The observed differences between groups in the ABI were significant after adjusting the effects of age and sex (P < 0.05). There was an association observed between ABI and HbA1C in diabetes patients (r = 0.249, P < 0.01) and a significant association seen between PAD and HTN in the prediabetes group (P < 0.01).
Peripheral arterial disease is common in asymptomatic diabetes and prediabetes patients. Management of hypertensive prediabetes patients and early detection of PAD in this group as well as in asymptomatic patients is important.

Previous studies have showed some evidences about the relationship between personality traits particularly neuroticism and extroversion, separately, with psychological stress and anxiety. In the current study, we clarified the magnitude of joint interdependence (co-morbidity) of anxiety (continuous) and Psychological stress (dichotomous) as dependent variables of mixed type with five-factor personality traits as independent variables.
Materials and Methods:
Data from 3180 participants who attended in the cross-sectional population-based “study on the epidemiology of psychological, alimentary health and nutrition” and completed self-administered questionnaires about demographic and life style, gastrointestinal disorders, personality traits, perceived intensity of stress, social support, and psychological outcome was analyzed using shared random effect approach in R Free software.
The results indicated high scores of neuroticism increase the chance of high psychological stress (odds ratio [OR] = 5.1; P < 0.001) and anxiety score (B = 1.73; P < 0.001) after adjustment for the probable confounders. In contrast, those who had higher scores of extraversion and conscientiousness experienced lower levels of anxiety score (B = −0.54 and −0.23, respectively, P < 0.001) and psychological stress (OR = 0.36 and 0.65, respectively, P < 0.001). Furthermore, higher score of agreeableness had significant negative relationship with anxiety (B = −0.32, P < 0.001).
The present study indicated that the scores of neuroticism, extraversion, agreeableness and conscientiousness strongly predict both anxiety and psychological stress in Iranian adult population. Due to likely mechanism of genetic and environmental factors on the relationships between personality traits and psychological disorders, it is suggested to perform longitudinal studies focusing on both genetic and environmental factors in Iranian population.

We assessed the effects of low-dose IV ketamine-midazolam versus morphine on pain control in patients with closed limb fracture(s); and also compared the incidence of adverse events (cardio-pulmonary) between two groups.
Materials and Methods:
This prospective, single-blind, non-inferiority trial randomized consecutive emergency department (ED) patients aged 18-60 years to two groups: Receiving 300-500 mcg/kg ketamine plus 0.03 mg/kg midazolam, or 0.05-0.1 mg/kg morphine. Visual analogue score (VAS) and adverse events were verified during an interval of 30 minutes.
Two hundred and thirty — six patients were selected, among whom 207 were males (87.3%). The average age was 29 ± 2, (range, 18-60 years). The VAS score at T30 (i.e., 30 minutes after initial analgesic dose) was significantly decreased compared with VAS score at T0, in both groups. No statistically significant difference, however, was observed between the two groups (–6.1 ± 1.1 versus –6.2 ± 1.0; P = 0.16). With regard to systolic blood pressure and respiratory rate, however, a meaningful difference was noted between the two groups (1.5 ± 6.4 versus –2.1 ± 6.6; P = 0.000 for SBP, and –0.2 ± 1.1 versus –1.1 ± 6.1; P = 0.048 for RR).
Low-dose intravenous ketamine plus midazolam has the same analgesic effects as morphine on pain control in trauma patients with closed limb fracture(s), in addition to less respiratory adverse events.

Supporting a therapeutic approach and medication therapy management, the pharmacy information system (PIS) acts as one of the pillars of hospital information system. This ensures that medication therapy is being supported with an optimal level of safety and quality similar to other treatments and services.
Materials and Methods:
The present study is an applied, cross-sectional study conducted on the PIS in use in selected hospitals. The research population included all users of PIS. The research sample is the same as the research population. The data collection instrument was the self-designed checklist developed from the guidelines of the American Society of Health System Pharmacists, Australia pharmaceutical Society and Therapeutic guidelines of the Drug Commission of the German Medical Association. The checklist validity was assessed by research supervisors and PIS users and pharmacists.
The findings of this study were revealed that regarding the degree of meeting the standards given in the guidelines issued by the Society of Pharmacists, the highest rank in observing input standards belonged to Social Services hospitals with a mean score of 32.75. Although teaching hospitals gained the highest score both in process standards with a mean score of 29.15 and output standards with a mean score of 43.95, the private hospitals had the lowest mean score of 23.32, 17.78, 24.25 in input, process and output standards, respectively.
Based on the findings, it can be claimed that the studied hospitals had a minimal compliance with the input, output and processing standards related to the PIS.

Excess serum uric acid (UA) accumulation can lead to various diseases. Increasing evidences reveal that UA may have a key role in the pathogenesis of metabolic syndrome. Little is known about the associations of UA levels with cardiometabolic risk factors in prediabetic individuals. This study was designed to evaluate the association between UA and cardiometabolic risk factors in prediabetic subjects with family history of diabetes compared with those with normal glucose tolerance (NGT).
Materials and Methods:
In a cross-sectional setting, a sample containing 643 (302 prediabetic subjects and 341 normal) of the first-degree relatives of diabetic patients aged 35-55-years old were investigated. Samples were assessed in prediabetic and normal groups using glucose tolerance categories. Prediabetes was defined based on American Diabetes Association (ADA) criteria. Body weight and height, systolic and diastolic blood pressure (SBP and DBP), UA, creatinine (Cr), albumin (Alb), fasting blood glucose (FBG), hemoglobin A1c (HbA1c), and lipid profiles were measured and compared between two groups.
Prediabetic persons were older and obese than normal persons. Also, prediabetic persons (5.2 ± 1.3 mg/dl) had significantly higher UA than normal persons (4.9 ± 1.4 mg/dl) (P < 0.05). FBG after 0, 30, 60, and 120 min in prediabetic were higher than normal persons (P < 0.001). With respect to metabolic parameters, the patients in the higher UA quartiles exhibited higher levels of body mass index (BMI), SBP, FBG and triglycerides (TG). The higher quartiles of UA tended to be associated with higher BMI and higher total cholesterol (TC) in females prediabetic persons. Based on logistic regression analysis in different models, UA was positively (odds ratio (OR) >1, P < 0.05) associated with glucose tolerance categories. This association remained statistically significant after adjusting the effects of age and BMI. Also, the association between glucose tolerance categories and UA were positively significant in both genders.
High UA level was associated with some cardiometabolic risk factors in prediabetic individuals compared with normal person. UA level was also a significant predictor for prediabetes condition.
