RESUMO
Medicinal plants are widely used as a complementary therapy to treat complex diseases, such as nonalcoholic fatty liver disease (NAFLD). Therefore, this study was done to investigate the effect of co-administration of artichoke leaf extract supplement (ALES) with conventional medicines on patients with NAFLD. The clinical trial was based on patients randomly divided into three groups involving metformin-vitamin E (ME), metformin-ALES (MA), and vitamin E-ALES (EA). The effectiveness of treatment in the treated groups was evaluated using liver ultrasonography and biochemical markers. After 12 weeks of treatment, the results showed that the rate of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was significantly reduced within all the study groups (p < .05). Liver ultrasonographic findings revealed that the rate of fat accumulation in liver of patients was decreased significantly within all the study groups and it was increased in the subjects with grade 0 fatty liver (without fat accumulation) in the MA and EA groups by 23.3 and 17.2%, respectively. In summary, the results of the present study showed that the concomitant use of ALES with metformin and vitamin E can have beneficial effects on amelioration of complications in patients with NAFLD. However, larger-scale clinical trial studies are required in this regard.

Organophosphorus pesticides (OPPs) are a group of pesticides that are most widely used in the agricultural sector, and farmers are exposed to these chemicals more than other members of society. In this work, an environmentally friendly, simple, and safe ultrasound-assisted dispersive liquid-liquid microextraction (USA-DLLME) method using alcohol-based hydrophobic deep eutectic solvents (HDESs) followed by gas chromatography-mass spectroscopy (GC-MS) was developed for the extraction and determination of OPPs in the blood of farmers studied in Ravansar cohort. DESs synthesized from thymol as hydrogen bond donor (HBD) and aliphatic alcohols as hydrogen bond acceptor (HBA) have been used as extractants. Under optimal experimental conditions, the reproducibility of the method based on 7 replicate measurements of 10 µg L-1 of OPPs in blood samples was in the range of 1.4-3.8%. The method showed a linearity in the range of 0.01-150 µg L-1. The limits of detection and limits of quantification were between 0.003 and 0.02 µg L-1 and 0.01-0.05 µg L-1, respectively. The matrix effect and accuracy of the method were confirmed by spiking different amounts of OPPs in real blood samples and obtaining relative recoveries in the range of 91-112%. The results showed that the concentration of OPPs in the case group was significantly higher than in the control group, which is because the case group was exposed to OPPs during the spraying of agricultural products.

In this research, an environmental friendly, green and efficient sample preparation method using vortex-assisted microextraction based on a deep eutectic solvent (VAME-DES) followed by graphite furnace atomic absorption spectrometry (GFAAS) was developed for the preconcentration and determination of As(iii)/As(v) and total inorganic arsenic in soil and vegetables irrigated with treated municipal wastewater from Tehran and Kermanshah, Iran. In the proposed method, a novel DES, characterized by its low density, was prepared by mixing choline chloride and citric acid monohydrate at a molar ratio of 1 : 1. Under optimal conditions, the proposed method enabled the achievement of a good enrichment factor of 175. The calibration graph was linear in the range of 0.3-100 µg kg-1 and the limit of detection (LOD) was 0.10 µg kg-1. The repeatability and reproducibility of the method based on seven replicate measurements of 50 µg kg-1 As(iii) in analysed samples were 4.2% and 6.5, respectively. The relative recoveries from soil and vegetables that were spiked with different levels of As(iii) and As(v) were 94.2-104.3 and 91.0-107.0%, respectively. The main advantage of the proposed method is the use of a non-toxic and non-volatile DES instead of volatile organic solvents. The accuracy of the proposed procedure was also assessed by the speciation of arsenic in two standard reference materials (GBW10014 cabbage and GBW10015 spinach). The extraction methodology is simple, rapid, cheap and green, since only small amounts of non-toxic solvents are necessary.
RESUMO
Background. This study investigated the effect of non-surgical periodontal treatment on clinical indices and salivary levels of visfatin, chemerin, and progranulin in diabetic patients with periodontitis. Methods. This interventional clinical trial was performed on 20 patients with type II diabetes mellitus (T2DM) with moderate to severe chronic periodontitis (periodontitis stages II or III according to the new classification of periodontal diseases). Clinical indices, including gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and plaque index (PI), were recorded and visfatin, chemerin, and progranulin adipokines levels were also measured in unstimulated saliva by ELISA technique at baseline and twelve weeks after non-surgical periodontal treatment. Results. GI dropped from 1.92±0.27 to 0.71±0.14 after the intervention (P<0.001). Also, there were significant changes in the PPD and PI (P<0.001). However, no significant changes were observed in the CAL (P<0.05). The concentrations of all three salivary adipokines decreased after treatment, but this change was statistically significant only for progranulin (P<0.05). Conclusion. Non-surgical periodontal therapy resulted in improvements in the clinical indices of GI, PPD, and PI in T2DM patients with periodontitis. Moreover, the significant reduction in the salivary level of progranulin after treatment suggests that it might be considered a target inflammatory marker in periodontal diseases.
RESUMO
Breast cancer is the most common cancer among women. The present study investigated the stage of breast cancer screening adoption and the role of some of the cognitive predictors in a sample of Iranian married women. There were a total of 334 married women clients of eight health centers in Kermanshah city, the west of Iran, were randomly selected to participate voluntarily. Women filled out a self-report questionnaire. Data were analyzed by SPSS version 20 using One-way ANOVA, χ2-test, Fisher's exact test, and bivariate correlations statistical tests at 95% significant level. The mean age was 39.75 years [SD: 7.73]. Nearly 58.4%, 26.9%, 3%, 9.6%, and 2.1% of the respondents were reported pre-contemplation, contemplation, preparation, action, and maintenance of breast cancer screening adoption, respectively. There was a significant association between age (P=0.005), and positive family history of breast cancer (P=0.037), perceived susceptibility (P=0.005), perceived severity (P=0.001) and knowledge of symptoms (P=0.018) with breast cancer stage of screening adoption. Our findings can provide better knowledge for the development and implementing of stage-targeted breast cancer screening adoption promotion programs. We conclude that it seems that the focus of health planner should be to rise to perceived severity; perceived susceptibility and knowledge of symptoms of breast cancer about the promotion of breast cancer screening adoption an Iranian woman.

BACKGROUND: Self-immolation is one of the most violent methods of suicide in developing countries. The objective of the present study was to investigate the survival rate and factors affecting survival of self-immolation patients. METHODS: All people either died or hospitalized for intentional burns were assessed in Kermanshah province between 2010 and 2013. Required information was gathered from two sources, Kermanshah province legal medicine and burn center of Imam Khomeini Hospital. Survival function was assessed through Cox regression. The data were analyzed with Stata 12 software. RESULTS: Between 2010 and 2013 (three years), 446 people attempted self-immolation, of which 370 were females (83%). In general, 276 people (61.8%) died due to severity of the burns. The median of survival time was 47±5 days. The survival rate after one day, one week, and 21 days after accident was 86%, 52%, and 38%, respectively. Multivariate analysis demonstrated that burn was the most powerful risk factor, sothe risk in those with over 70% burns is 17 times more than those with burns less than 30%. CONCLUSION: Burn percentage is the strongest risk factor, those with high burns percentage should be hospitalized quickly and without waste of time.

BACKGROUND: Fitness is a very important goal among young adults that may lead to eating disorders. OBJECTIVES: The aim of this study was to identify the factors influencing fitness intention based on the theory of planned behavior (TPB) and its relationship to eating attitudes. MATERIALS AND METHODS: A cross-sectional study was conducted among 231 female college students during the winter of 2012. Participants were randomly selected in proportion to their distribution among the different faculties at Hamadan University of Medical Sciences. A structured questionnaire was applied for collecting data and data was analyzed by SPSS version 21 using a T-test, ANOVA, bivariate correlations, and linear regression at a 95% significant level. RESULTS: Nearly 21.6% of the participants had abnormal eating attitudes. The TPB variables accounted for 40% of the variation in fitness intention. Bivariate correlations indicated a positive correlation between fitness intention and eating attitude (r = 0.417, P < 0.05). CONCLUSIONS: Based on our results, it seems that designing and implementing educational programs to reduce positive attitudes and encourage subjective norms toward fitness may be useful for preventing abnormal eating attitudes.
RESUMO
BACKGROUNDS: Drug abuse is one of the most serious social problems in many countries. College students, particularly at their first year of education, are considered as one of the at risk groups for drug abuse. The present study aimed to determine cognitive factors related to drug abuse among a sample of Iranian male medical college students based on the social cognitive theory (SCT). METHOD: This cross-sectional study was carried out on 425 Iranian male medical college students who were randomly selected to participate voluntarily in the study. The participants filled out a self-administered questionnaire. Data were analyzed by the SPSS software (ver. 21.0) using bivariate correlations, logistic and linear regression at 95% significant level. RESULTS: Attitude, outcome expectation, outcome expectancies, subjective norms, and self-control were cognitive factors that accounted for 49% of the variation in the outcome measure of the intention to abuse drugs. Logistic regression showed that attitude (OR=1.062), outcome expectancies (OR=1.115), and subjective norms (OR=1.269) were the most influential predictors for drug abuse. CONCLUSIONS: The findings suggest that designing and implementation of educational programs may be useful to increase negative attitude, outcome expectancies, and subjective norms towards drug abuse for college students in order to prevent drug abuse.

BACKGROUND: Substance abuse is one of the most complicated social problems. Understanding socio-demographic characteristics of those who abuse substances could help deal with this problem more efficiently. The main objective of this study was to determine socio-demographic characteristics associated with alcohol drinking, cigarettes smoking and drug abuse among a sample of male medical university students in Iran. METHODS: This cross-sectional study was conducted in 2014 among 425 male medical college students randomly selected with the proportional to size among different faculties in Isfahan and Kermanshah medical universities in Iran. A self-report written questionnaire was applied to collect data. Data were analyzed by the SPSS-20. RESULTS: Mean age of the respondents was 19.9 yr (ranging from 18 to 22 yr). About 19.4%, 3.9%, and 10.1% of the respondents had history of cigarette smoking, drug use, and alcohol drinking during the past three months, respectively. Logistic regression showed that mother's educational level, living place, economic status, and parents' divorce were the most influential predictive factors on substance abuse. CONCLUSIONS: Considering the high prevalence of substance abuse (especially smoking and alcohol drinking), it seems essential to design educational interventions to prevent substance abuse, paying attention to predictive factors mentioned above, among college students.

Ritalin misuse can create powerful stimulant effects and serious health risks. The main aim of present study was compared that two cognitive construct (behavioral intention or behavioral willingness) for predicting Ritalin misuse. This cross-sectional study was conducted among 264 Iranian medical college students; participants selected in random sampling, and data were collected by using self-report questionnaire. Data were analyzed by SPSS version 21 at 95% significant level. Our findings showed, the three predictor variables of (1) attitude, (2) subjective norms, and (3) prototype accounted for 29% of the variation in intention and 25% of the variation in willingness to Ritalin misuse. In addition, behavioral intention was a stronger prediction factor compared to willingness for Ritalin misuse, with odds ratio estimate of 1.607 [95% CI: 1.167, 2.213]. There is some support to use the prototype willingness model to design interventions to improve individuals' beliefs that academic goals are achievable without the misuse of Ritalin.
