Background: The German cockroach, Blattella germanica L. (Dictyoptera: Blattellidae), has become resistant to many insecticides due to control failures in hospital and student dormitory settings of southern Iran. Objective: This study was thus designed to detect and monitor carbamate resistance in two strains of German cockroach using lethal dose bioassay methods. Methods: Wild dormitory (D) and hospital (H) strains were collected. Adult males were subjected to the jar exposure procedure. A range of concentrations based on the world health organization (WHO) standard concentration of carbamate insecticides (carbaryl, bendiocarb, propoxur) were used. For each insecticide, four to seven different concentrations leading to >0% and propoxur > bendiocarb. The ratio of LD50 in H strain to that of D strain for bendiocarb was about twice that of the other two insecticides indicating that German cockroaches were most susceptible to bendiocarb under both environments. Conclusion: It is concluded that excessive reliance on carbaryl in both D and H settings has led to resistance.

Health care system is organized to achieve more efficiency as well as developing public equity and providing access to the first, second and third levels of services. Family physician is in the first line of the health care system; in other words, family physician is the health system’s goalkeeper. According to classification of health services, gaining access to specialized services becomes possible through the referral system.1 Referral system is a system in which the client should primarily refer to the family physician in order to gain access to health care services and be referred to a specialist if necessary. The specialist refers the patient to the family physician for following treatment modalities after doing necessary medical care and advice and recording the results in the feedback form.2 Despite the different levels of service delivery, the boundaries between these levels are not clear enough and have caused problems in the referral system. Certainly, for better implementation of family physician plan, empowering family physicians, clarifying the referral procedure, and localizing its components are of great importance. One of the life long concerns of the Ministry of Health and Medical Education, especially Shiraz University of Medical Sciences, has been developing clinical guidelines to empower family physicians based on clinical referral system and local conditions of the country. Among effective measures in this field is preparing clinical guidelines, according to the level of services and in line with the referral system. The purpose of developing clinical guidelines is improving the quality of health care and increasing the patient’s satisfaction through the following specific objectives:

Compiling clinical guidelines is one of the requirements of family physician plan and classification of health care services.1 The high prevalence of type 2 diabetes can easily be seen in general practice so that 2.5% of referrals to general practitioners are due to diabetes. More than half of the patients with Type 2 diabetes are left undiagnosed and most of them suffer from its complications at the time of diagnosis. For example, 6.2% of patients suffer from diabetic retinopathy at the time of diagnosis.2 Most patients diagnosed with diabetes take more than one type of medication to treat the complications; about 60% take only oral medications, and 14 percent take oral medications and insulin.3 Although the principles of care for people with Type 2 diabetes is well known, there is a gap between the quality of care in general practice and optimal care so that up to 50% of patients’ condition are weakly controlled.4 Chronic care model for patients with chronic diseases explains the necessary measures to improve the care of people with chronic diseases. These elements include supporting disease management by the patients themselves, patient care, and support teams. Consultation and training are often done in general practice while it is usually a brief consultation about weight, medication or exercise. There is little evidence that mere printed texts are effective in controlling the disease. Extensive training programs are designed to develop self-management skills for diabetes control.4 The implementation of clinical guidelines in medical practice is a challenging task. But, a number of evidences have been shown to accelerate effective clinical guideline implementation and care improvement.5 Management of diabetes mellitus type 2 is shown in Figure 1.

AbstractBackground: Dietary pattern is an effective way of studying the effect of diet on diseases. We investigated the association between dietary patterns and blood pressure (BP) in adults aged 20-50 years.Methods: In a cross-sectional design, 418 individuals were selected through stratified multistage random sampling from households living in different regions of Shiraz. Information on demographic characteristics, anthropometric features, dietary intakes, and systolic (SBP) and diastolic (DBP) blood pressure was gathered. Dietary patterns were determined using a validated food frequency questionnaire.Results: Three dietary patterns were specified: vegetable (high in vegetables and legumes), Western-like (high in meat, sugarsweetened beverages, salty and sweet snacks, refined grains, high-fat dairy), and Mediterranean-like (rich in low-fat dairy, fruit, vegetables, nuts, olive, fish, and low in hydrogenated fats). After adjustment for confounders, Mediterranean-like dietary pattern had an inverse association with SBP (β=-0.24; 95% CI: -5.25, -1.27) and DBP (β=-0.17; 95% CI: -3.65, -0.20) in males but not females. Vegetable and Western-like dietary patterns were not associated with BP in either sex after adjusting for confounders. Positive relationships were observed between BP and body mass index (r=0.28 and 0.33 for SBP and DBP, P<0.001), waist circumference (r=0.51 and 0.45 for SBP and DBP, P<0.001), and waist-to-hip ratio (r=0.54 and 0.44 for SBP and DBP, P<0.001). Dietary energy and carbohydrates were positively and fats inversely associated with BP. Among micronutrients, vitamin E had a significant inverse association with BP.Conclusion: Mediterranean-like dietary pattern may lower the risk of hypertension in Shiraz males.

Background: Complete and fast diagnosis, registry and treatment programs are the main effective strategies for controlling infectious diseases. In addition, an organized and extended infectious disease surveillance system is crucial in designing and monitoring communicable diseases control programs. The quality of the surveillance system can be evaluated by several indices such as timeliness, completeness and sensitivity. This is an evaluation study to measure the mentioned indices for 3 zoonotic diseases (leishmaniasis, brucellosis and rabies) surveillance system. Methods: The indexes such as completeness, timeliness and sensitivity of surveillance system were measured using the data obtained from population based (door to door) interviews and recorded data obtained at each level of health and medical sectors or administrative centers within the diseases reporting system. Interviews were conducted for 5969 participants and the required information was obtained. Results: The total completeness, timeliness and sensitivity of case reporting for leishmaniasis were 26.9%, 103.2 days and 11.1%, respectively. These indexes forbrucellosiswere14.3 %, 58 days, 12.1% and those for suspected rabieswere100%, 83.4 days and 48.2%, respectively. Conclusion: It seems that so called immediate communicable diseases reporting system is not providing reliable, complete and timely information to the health authorities. Program monitoring and personnel training, especially physicians, are recommended to improve the quality of the surveillance system and the related indexes.

Background: Landfills are the most important producers of methane as human source. So, prediction of landfill gas generation is by far the most important concern of scientists, decision makers, and landfill owners as well as health authorities. Almost all the currently used models are based on Monod equation first order decay rate which is experimental while the main purpose of this research is to develop a numerical model. Methods: A real scale pilot landfill with 4500 tons of municipal solid waste has been designed, constructed, and operated for two years. Required measurements have been done to provide proper data on greenhouse gases emitted by the landfill and monitor its status such as internal temperature, leachate content, and its settlement during two years. Afterwards, weighted residual method has been used to develop the numerical model. Then, the newly mathematical method has been verified with data from another landfill. Results: Measurements showed that the minimum and maximum percentages of methane among landfill gas were 22.3 and 46.1%, respectively. These values for velocity of landfill gas are 0.3 and 0.48 meters per second, in that order. Conclusion: Since there is just 0.6 percent error in calculation as compared to real measurements from a landfill in California and most of the models used have ten percent error, this simple empirical numerical model is suggested to be utilized by scientists, decision makers, and landfill owners.

AbstractBackground: Sleep disorders like snoring, mouth breathing, andinsomnia are frequent in pregnancy and studies have shown thatpoor sleep is linked to obstetric complications. Muscle relaxationtechnique is an effective method used for improving sleepquality. The purpose of this study was to determine the effectof muscle relaxation technique on fetal outcomes in complicatedpregnancies with sleep disorders.Methods: This study was performed as a clinical trial on 160pregnant women who suffered from preeclampsia and gestationaldiabetes. The participants filled the Pittsburgh Sleep QualityIndex (PSQI) in order to measure the quality and patterns oftheir sleep. The participants with the total score of 5 or morewere included in the present study. Intervention group were askedto use muscle relaxation technique twice a week at home for 8weeks alongside the routine care. Study variables included sleepquality, Apgar scores, birth weight, levels of Interleukin- 6 (IL-6), as well as umbilical cord PH and PO2.Results: The mean score of PSQI before the intervention was9.28±4.16 and 9.18±3.06 in the intervention and control groupswithout a significant difference (P=0.6), respectively. However,PSQI global score of the experimental group was smaller than thecontrol group at the end of the study (P<0.001). Also, birth weight(P=0.04), Apgar score (P=0.01), and umbilical cord blood po2(P=0.03) and PH (P=0.01) were higher, and IL-6 (P=0.04) wassmaller in the experimental group compared to the control group.Conclusion: The results of this study showed that musclerelaxation, as a simple, inexpensive and safe method, canimprove the fetal outcomes such as birth weight, Apgar score,cord blood po2, and cord blood PH, and also it leads to lowerIL-6 in complicated pregnancies.

Background: Most workers are exposed to a variety of hazards in their workplace. Devising a comprehensive checklist and developing an index for Occupational Safety and Health (OSH) assessment could be useful. This study was conducted in a heavy automotive company with the aim of developing and validating an OSH assessment index.Methods and Materials: We used the experiences and comments of OSH experts to devise a checklist for OSH assessment. Weighting various harmful factors was done using Analytical Hierarchy Process (AHP) technique. Intra-class Correlation Coefficient (ICC) was applied to measure the reliability of the checklist (SPSS version 20). In the studied industry, 150 workstations were assessed using the developed comprehensive checklist. In order to validate the total index, we assessed its correlation with 4 groups of occupational statistics (i.e. accident frequency, severity rates, lost working time rate, and occupational disease incidence rate). A p value of < 0.05 was considered significant.Results: Among 7 sub-indices, sub-indexes of occupational health and the workplace order (w=0.21) and housekeeping (w=0.04) had the highest and the lowest AHP weights, respectively. The mean of ICC was found to be 0.978. The total index (OSHITotal) and the Accident Severity Rate (ASR) had a strong inverse significant correlation (r = -0.774, P=0.002).Conclusion: The developed index covered important occupational hazards. The inter-evaluator reliability for this index was high.

AbstractBackground: In this cross-sectional study, 501 employees of petrochemical companies were selected by simple sampling method.Methods: Data were collected using Swedish Occupational Fatigue Inventory (SOFI-20), Occupational Fatigue/Exhaustion Recovery (OFER-15), and General Health Questionnaire (GHQ-28). To identify the factors associated with fatigue and general health, we used ordinary least squares regression (OLS) and SUR and the results were compared. The analysis showed that satisfaction, mental disorder and sleepiness were the important factors associated with fatigue among these workers. However, the SUR estimator provided higher precision of the estimates than the OLS estimator as the parameters obtained by SUR are characterized by lower standard errors. As the models are intended to predict the fatigue risk factors, we particularly focused on the SUR method because it assesses the precision of the model in predicting fatigue determination. SUR estimators performed consistently better than the OLS estimators since SUR takes the correlation between error terms into account. Results: The findings showed that the study population were young and almost had a low job tenure. The correlation test showed that there was a significant relationship between fatigue and general health with job satisfaction (p=0.05), sleep disorder (p=0.01) and mental disorder (p=0.001). Finally, the analysis showed that fatigue as the result of work was affected by some organizational and individual risk factors, among which "general health status" in general fatigue and "job satisfaction and mental disorders" in mental, physical, shift work, chronic and acute fatigue had the most effect.Conclusion: The prevalence of fatigue among the study population was assessed high. Thus, elimination and reduction of casual risk factors are necessary to reduce the prevalence of fatigue at work environmental.

Introduction: Environmental health is definitely one of the issues and challenges considered by human societies on the eve of the third millennium. Therefore, the present study was conducted to determine the knowledge, attitude and performance of the people of Fasa on segregation of municipal solid wastes in 2017. Method: This cross – sectional study was conducted on 400 residents of Fasa who were selected through cluster sampling. The tool used in this study was a Lickert-spectrum questionnaire, which was essentially a combination of two standard instruments and the researcher’s field studies. The data were analyzed using the SPSS 22 software as well as descriptive statistics, Man-Whitney test and one – way ANOVA test. Results: The results of this study showed that the mean knowledge, attitude and performance of the people were 23.5±5.3, 13.5±3.0, and 21.5±2.6, respectively. 43.7% of the subjects had weak knowledge (188 people), 28.6% had moderate knowledge (123 people) and 27.7% had good knowledge (119 people). Moreover, 36.6% had weak attitude (156 people), 19.3% had moderate (85 people) and 44% had good attitude (189 people). Finally, the performance of 46% of the participants was weak (198 people), that of 30.5% was moderate (131 people), and 23.5% had good performance (101 people). The mean scores of knowledge, attitude and performance of the male and female subjects were not significantly different.

Background: Malaria is one of the most important vector-borne diseases, a major health problem, and a serious cause of mortality around the world. Indoor Residual Spraying (IRS) together with insecticide-treated nets is among the primary methods used for controlling and reducing the burden of malaria. The present study aimed to determine the appropriate time for malaria management based on entomology, vector abundance, temperature, and precipitation data. Methods:The study data were collected using the entomological data existing in Kazerun’s health and treatment network and weather station between 2009 - 2016. The data were analyzed via time series models with monthly time intervals, which included 96 months. The following models were applied: Autoregressive Moving Average (ARMA), Moving Average (MA), Autoregressive (AR), and Autoregressive Integrated Moving Average (ARIMA). Indeed, kriging approach was employed for interpolation of temperature and precipitation in the study points. All analyses were done using Information Technology Service Management (ITSM) software. Results: Temperature followed a similar trend in the six villages under investigation. It was predicted up to 20 months after the observations using MAmodel. Accordingly, the mean of temperature was 30°C.The trend of precipitation showed great fluctuations; thus, the results of the precipitation model were not accredited. The trend of Anopheles abundance was predicted using ARMA in Jahad-Abad, Hakimbashi, Seyed Hossein, and Dadin and using ARMA in Khesht and Jareh. According to the results, Anopheles abundance followed a descending trend in the study regions. Considering the temperature trend and peak of Anopheles abundance in the areas under investigation, the best time for residual spraying was two weeks prior to the peak of Anopheles abundance within the temperature range of 25-30°C. Conclusion: Considering entomology and temperature data, two weeks prior to the peak of Anopheles abundance within the temperature range of 25-30°C was found to be the best time for residual spraying in order to prevent and control malaria. Other preventive and control measures, such as active case detection, timely treatment of patients, and public education should also be intensified at this time.

Background: Several items affect the use of dental services. The objective of this study was to assess the association between socio-economic status (SES) and dental insurance coverage with the use of dental services amongst Iranian adolescents aged 13-15 years old. Methods: In this cross sectional study, we used a researcher-made questionnaire to assess the association between socio-economic status (SES) and dental insurance coverage with the use of dental services in 423 Iranian adolescents aged 13-15 years old. Statistical Package for Social Sciences (SPSS) was used to analyze the data, generate descriptive statistics, and perform multiple logistic regressions. Results: Use of dental services was statistically significant amongst the students with dental insurance and parents with higher income (P<0.001), which was independent of the other socio-economic factors (parent’s age, education and marital status). Conclusion: The results showed that one of the important policies to reduce inequality in dental care is to improve dental insurance coverage.

Background: Safe performance and patient safety are two important issues in the delivery of healthcare services. Non-technical skills are necessary for safe performance of anesthesiologists in the operating room. This study aimed to assess the anesthetists’ non-technical skills in Iranian hospitals. Methods: This cross-sectional study was conducted on 38 anesthetists working in orthopedic surgery wards of two hospitals in 2019. The data were collected using the Anesthetist’s Non-Technical Skills (ANTS) system, which included four domains, namely task management, teamwork, situation awareness, and decision-making. The anesthetists were assessed by a trained observer via observing and recording the events during surgeries. Results: The mean score of ANTS was 10.12±1.66 out of 16. Among the four skills, the highest and lowest mean scores were related to “task management” (2.94 out of 4) and “decision-making” (2.26 out of 4), respectively. Work experience showed a significant positive relationship with “decision-making” (p=0.008, r=0.974). However, higher education level was not associated with improved anesthesiology skills. Conclusion: The quality of non-technical skills was below the acceptable level in the studied anesthetists. Thus, it is recommended that the anesthetists’ skills should be improved through educational and political interventions.

Background: The application of insecticides against vector mosquito larvae is a crucial step to control human malaria. Insecticide resistance is a major impediment to vector control strategies. The main aim of this study was to conduct laboratory and semi-field evaluations on lethal and residual effects of temephos and pyriproxyfen insecticides against malaria mosquito larvae, Anopheles stephensi. Methods: Both susceptibility test and residual bioassay were performed to assess the lethal concentrations of each insecticide on 50% (LC50) of the IV instars larval populations and their activity periods according to standard protocols of WHO. Nine and eleven different concentrations with two sets of control in each case were applied for temephos and pyriproxyfen, respectively. Data were analyzed using probit analysis and SPSS software. Results: The LC50 and LC90 for temephos and pyriproxyfen under laboratory conditions were 0.4 and 0.63, and 1.69 × 10-4 and 4.036 × 10-4 ppm, respectively. Although the field strain of An. stephensi larvae was completely susceptible to pyriproxyfen, there was noticeable resistance (8% mortality at the diagnostic dose) to temephos in Nikshahr County, Southeast Iran. This is the first report of resistance to temephos for this malaria main vector in Iran. Depending on the applied variable doses, the residual effects of temephos and pyriproxyfen under semi-field conditions lasted maximally for 3 and 10 weeks, respectively. Conclusion: The high lethal and residual effects of pyriproxyfen on mosquito larvae confer an unprecedented opportunity in vector control operations leading to elimination of malaria in Iran.

Objective: Individualized Medical Nutrition Therapy (IMNT) is recommended as a part of glycemic control in hospitalized diabetic patients. However, it is provided only for a small number of patients. This study aimed to compare the effects of IMNT and Consistent Carbohydrate Meal-Planning (CCMP) on glycemic control, energy, and carbohydrate and protein intake in hospitalized diabetic patients. Methods: This randomized clinical trial was conducted on 164 hospitalized diabetic patients. The patients were randomly selected from internal wards of Namazi hospital, Shiraz, Iran from September 2016 to October 2017. They were allocated to IMNT or CCMP groups using simple randomization for four days. Blood glucose was measured before each meal and at bedtime. A 24-h food recall was also completed to measure the energy and carbohydrate and protein intake during the study. The data were analyzed using independent sample t-test and repeated measures ANOVA via the SPSS software, version 19. Results: The results showed a significant decrease in the IMNT group compared to the CCMP group regarding the mean blood glucose level measured prior to breakfast, lunch, dinner, and bedtime during the first, second, third, and fourth days of the study (p=0.025, p=0.030, p=0.002, and p=0.011, respectively). Besides, mean peak and nadir of glucose level (p=0.042 and p=0.036, respectively) and the means of energy, carbohydrate, and protein intake were significantly increased in the IMNT group compared to the CCMP group. Conclusion: IMNT could help to control the blood glucose. In addition, it could improve energy and nutrients intake, which might play a role in patient recovery.

Background: Human resources are considered as one of the most important production resources and the basic capital of the organization. This study aimed to investigating the relationship between job motivation and job performance of auxiliary nurses under the coverage Shoush health centers. Methods: This cross-sectional study was carried out on auxiliary nurses under the coverage of Shoush health centers in 2017. Auxilliary nurses were enrolled in the study using census sampling method (150 people). The data collection tools were Herzberg's job motivation questionnaire and Paterson's job performance questionnaire that were completed through the self-report method. Data were analyzed through SPSS-22 software using Pearson correlation and multiple regression tests. Results: Ninety-nine people (66%) were female and 51 (34%) were male. The average motivation and job performance of the subjects were 184.22±14.98 and 42.50±6.26, respectively. According to the results of Pearson correlation test, there was a significant relationship between motivation and job performance (r=-0.223, p=0.006). According to the results of multiple regression, personal relationships with each other and work environment conditions predicted 22 percent of changes in performance of auxiliary nurses. Conclusion: In the present study, according to the relationship between motivation and job performance of health workers, it is suggested that measures should be taken to increase motivation to improve their job performance.

Background and Objectives: Activated carbon is an adsorbent which is mostly employed in order to remove dye from aqueous solutions; however, commercial activated carbon is expensive and this is considered as an obstacle for its usage. Therefore, the present study aimed to use waste paper as an inexpensive precursor to produce activated carbon. Materials and Methods: In the present study, KOH was used for the chemical activation process; in order to prevent the precursor oxidation during the carbonization process, a completely sealed furnace was used. In order to determine the characteristics of the prepared activated carbon texture, N2 gas adsorption and BET isotherm were used. Moreover, Langmuir, Freundlich, Temkin, and Redlich-Peterson isotherm models as well as Pseudo-first order, Pseudo-second order, and intra-particle diffusion kinetic models were used to determine the characteristics of Methylene Blue adsorption on the prepared adsorbent. Results: According to the results, SBET and VTOTAL were 66.01m2/g and 0.063cc/g, respectively. Ferudlich and pseudo-second order models were the best isotherm and kinetic models for prediction of the Methylene Blue adsorption on the produced adsorbent. Furthermore, the qmax constant from the Langmuir model was obtained as 68.03 mg/g. Conclusion: In comparison to other studies, the produced activated carbon in the present study had a desirable surface area and adsorptive capacity for methylene blue adsorption in aquatic environments. Moreover, it seems that preparing activated carbon from waste newspaper is inexpensive, effective, and environment friendly.

Incidence of diabetes is increasing in developing countries as well as Iran. Half of the patients are not aware of their disease so screening of diabetes is necessary. Lifestyle changes in society, high-saturated fat diet and decreased physical activity are the factors that influence the growing rate of diabetes in Iran.1 The need for addressing type 2 diabetes has been clarified for family physicians.2 Diabetes is a common disease that is associated with significant morbidity and mortality. It has an asymptomatic stage that may be present for up to several years before diagnosis.3 Diabetes is the leading cause of kidney disease.4 In a study among patients over 45 years with type 2 diabetes, these results were reported: 22% suffered from retinopathy, 7% had impaired vision, 6% had kidney diseases, 9% had clinical symptoms, and 19.1% were at risk for foot ulcers.5 Early treatment of type 2 diabetes can reduce or delay complications.6 Optimal glycemia and BP are important in the prevention of diabetic chronic kidney disease (CKD).4 Therapeutic goals in patients with complications, such as CKD, include maintaining renal function and stopping the trend of renal deterioration.5 Progression of diabetic nephropathy can be slowed through the use of some medications.4 How to screen and manage chronic kidney disease in patients with type 2 diabetes is shown in Figure 1.

Cardiovascular disease (CVD) due to atherosclerosis is the foremost cause of premature mortality and of disability-adjusted life years (DALYs) in developed and developing countries (1). The associated mortality is preventable through treatment of dyslipidemia (2). Over half of the first CHD events and 3/4 of CHD deaths are preventable by controlling the risk factors, including diet, exercise, weight and blood pressure control; prescription of aspirin and tobacco cessation ; and lowering lipids (3). Dyslipidemia covers the broad spectrum of lipid abnormalities (4). However, elevations of the total cholesterol and low density lipoprotein cholesterol (LDL-C) have received the most attention (4). Epidemiologic data revealed that about 70 million Americans had elevated levels of LDL cholesterol between 2005 and 2008 (5). Abnormalities in lipid components are prevalent in Iran and they are more common among men in urban areas. Urbanization, unhealthy diet and sedentary lifestyle are the underlying reasons for the high prevalence of dyslipidemia in Iran (4). Dyslipidemias may be related to other diseases (secondary dyslipidemias); therefore, secondary causes of abnormal lipid levels should be considered first and treated when appropriate (6).The primary target in treating dyslipidemia has been and will probably continue to be LDL cholesterol because it is the most atherogenic lipoprotein which correlates more closely than other lipids with CHD (7). Statin therapy is likely to continue to be emphasized because they are the most effective lipid-lowering agents for reducing LDL cholesterol concentrations, and their efficacy for lowering the risk for cardiovascular events has been proven (8). Every 1.0 mmol/L (40 mg/dL) reduction in LDL-C is associated with a corresponding 22% reduction in CVD mortality and morbidity (9). Patients with an elevated LDL-cholesterol level should begin the Therapeutic Lifestyle Changes program as well as an individualized program of regular exercise. Lifestyle modifications include diet, aerobic exercise, weight control, smoking cessation, evaluation of alcohol consumption; and a nutritional supplement containing sitostanol ester, a saturated derivative of plants’ seed oil (6). Diet and exercise are the cornerstones of treatment for asymptomatic patients with dyslipidemia (6). Smoking cessation reduces coronary event rate by about 50% within one to two years of stopping. Among the benefits of smoking cessation is a 5-10% increase in HDL-C (3). Clinicians should initiate statin therapy regardless of LDL, in patients with established ASCVD. Statins are the drugs of choice for lowering LDL-cholesterol, and aggressive treatment with statins should be pursued (6). Large scale clinical event trials include lovastatin, pravastatin, simvastatin atorvastatin, and rosuvastatin (3). Statin Dose Intensity is shown in Table 1 (3).

Postpartum blues, as a transient phenomenon of mood changes, generally begins 1 to 3 days after the child birth.1 This phenomenon is accompanied with symptoms such as unstable moods, ranging from euphoria to sadness, high sensitivity, crying for no reason, restlessness, poor concentration, anxiety, irritability, and anger.2 Prevalence of postpartum blues has been estimated 44.3% in Hong- Kong,3 31.3% in Nigeria,2 and 58% in India.4 In Iran, 22.3% of women suffer from weak postpartum blues, 10.8% have medium, and 21.1% suffer from severe postpartum blues.5 Interaction between different biological, psychological and social factors could affect the postpartum blues.6 Some researchers have indicated that there is a reverse relationship between religion related beliefs and spiritual attitudes, participation in religious activities and reduction of pregnancy and postpartum anxiety and depression.7 Also, according to another study, 57% of the doctors believe that praying could enhance the healing effect of treatment.8 However, some other studies reject this idea.9-10 In this cross-sectional study conducted in selected prenatal clinics of Tehran University of Medical Sciences in 2013, 176 healthy pregnant women aged 18-35 years old participated. For assessment of postpartum blues, standard questionnaire of Edinburg Postnatal Depression Scale (EPDS)11 and Religious Attitude Scale (RAS-R) containing 25 questions with a Cronbach’s alpha of 0.954 in Iran were used.12

Abstract Background: The compounds which contain nitrogen entering the environment can cause some problems, such as eutrophication for water resources and potential risk for human health because of methemoglobinemia and cancer. Biological techniques are effective in removing nitrate. The aim of this study was to remove nitrate from groundwater using denitrification. The main objectives of this research were determining the reduction of water nitrate based on different retention time and also the effect of using grape extract as organic matter and electron acceptor in biological nitrate removal from water. Methods: In this experimental study, the effect of heterotrophic Pseudomonas separated from Shiraz wastewater treatment plant on removing nitrate from groundwater was investigated at pilot scale using grape extract as carbon source and filamentous media at constant pH (7±0.1) and temperature (20±1 °C). During this study, 2 pilots were made. Pilot number 1 was used for separation and growth of the above mentioned bacteria (Pseudomonas) that are able to remove nitrate. Pilot number 2 was also used for surveying the removal of nitrate by these bacteria. At least, 13 samples were examined in every retention time and each test was repeated for 2 or 3 times. Statistical analysis was performed in SPSS (ver.19) software using one-way repeated measures ANOVA, and Bonferroni tests. Results: According to the results, nitrate removal rates were 49%, 55%, 67% and, 67% at retention times of 1, 1.5, 2, and 2.5 hours, respectively. The best retention time was 2 hours with 67% removal rate (P<0.05). Conclusion: The results showed that using grape extract as the carbon source and proper growth of bacteria in filamentous media led to a significant increase in the removal rate.

Background: Soft drinks consumption is a major world public health concern. This study investigates the factors which influence the students’ intention to consume fewer amounts of soft drinks, using The Extended Parallel Process Model.Methods: This cross-sectional study was conducted on 320 high schools boys in Yazd, Iran (2014). A 15-item, 5-point Likert-type scale questionnaire was used to measure the participants’ perceived susceptibility, severity, response-efficacy and self-efficacy and intention about soft drinks’ consumption. Internal consistency (Cronbach alpha >0.7 for each construct) and external consistency: r = 0.79, P. =0.01) of questionnaire was approved. Data were analyzed by SPSS 16, using descriptive analysis, bivariate correlation, and stepwise multiple regression analysis. The level of significance was set at 0.05. Results: The participants’ average soft drink consumption was 3±3.4 daily glasses. Danger control processes had more frequency over fear control ones (57.7% vs. 42.3% of participants). The intention of fewer amounts soft drinks consumption was positively correlated with perceived response efficacy, self-efficacy and total efficacy. 16% of the participants’ intention variations were explained by self-efficacy. The odds of intention towards not to consume soft drinks were significantly higher for the high efficacy/ low threat category (OR=1.51, p= 0.04) compared with low efficacy / low threat category. Conclusion:The results revealed that inducing fear is not an effective way to promote healthy drinking behavior and the choice of fear appeals is often a poor choice in this subject. It can be suggested that health educators should move from traditional threatening fear arousal messages to improving their target audience’s self-efficacy.

Abstract Background: The mental workload and cognitive failures are among the factors affecting the human behavior, performance and efficiency, which are both effective on the human error and accidents of the drivers. This study was conducted to examine the relationship between cognitive failure and mental workload of taxi drivers in Shiraz.Methods: This descriptive-analytical and cross-sectional study was conducted on 200 taxi drivers in Shiraz in 2017. In order to measure the mental workload and cognitive failure, NASA-TLX mental workload questionnaire and CFQ cognitive failure questionnaire were used, respectively. Finally, statistical analysis was performed using SPSS version 21. Pearson correlation, T-test and one-way ANOVA tests were used to analyze the data statistically.Results: The taxi drivers' mental workload was reported relatively high in this study and the results showed that a significant relationship was found between mental and temporal workload and nominal memory error of drivers at 5% error level (p <0.05). Also, a significant relationship was observed between temporal pressure and performance and memory and attention, respectively (p<0.05). In general, a significant relationship was observed between total cognitive failure and total mental workload (p<0.05). Also, demographic factors as age had a significant effect on both mental workload and cognitive failure (p<0.05).Conclusion: The results of this study showed a significant relationship between the mental workload and cognitive failure, so that with increasing the mental workload, cognitive failure of taxi drivers also increased and the probability of the human error and consequently driving accidents increased. Therefore, reducing the mental workload with providing ergonomic solutions can greatly prevent the human error in driving as a major contributor to many accidents.

Introduction: Deaths from traffic accidents (RTIs) are a major public health problem in all societies, especially in the low and middle-income countries; the present study was conducted to investigate the epidemiology of fatal road traffic accidents in Ahvaz city. Methods: This is a cross-sectional study which included all deaths from RTIs in Ahvaz province (Southwest Iran) admitted to forensic medicine during 2015-2016. ICD-10 was used as diagnostic criteria. Demographic variables as well as injury circumstance) name, surname, phone number, age, sex, season, month, day, accident location, vehicle type, status of the injured person (were recorded by trained research team in forensic medicine. Descriptive data are reported. SPSS 20 software was used for analysis of data. Results: During years 2015-2016, a total of 50 deaths occurred due to road accidents in Ahvaz province. The mean age was 34.99 ± 19.98 years. The mortality rate was higher in men (79.4%), married subjects (57.4%), illiterate ones (26.2%), self-employed subjects (34.6%) and residents of urban areas (78.8%). There were statistically significant relationships between the accident location and the place of death, and between the trauma spot and the cause of death (P <0.001). Conclusion: The results of this study showed that most of the deceased were male, married and young, so preventive measures such as precise traffic surveillance and enforcement of the regulations for safe driving are considered essential.

Background: The presence of antibiotic residues in milk and other livestock by products is a health hazard that can endanger the public health. Antibiotics are widely used in animal husbandry to treat bacterial infections. In this industry, antimicrobial drugs are being used for decades; as a result, continuous administration of antibiotics to livestock had led to contamination of industrialized dairy farms. Background: This research was conducted to evaluate antibiotic residues in raw milk samples in Sepidan, using ECLIPS 50 kit and TWINE SENSOR kit. Methods: In this cross-sectional study, one hundred raw cow milk samples were randomly collected from different farms and milk factories in Sepidan and Beyza townships from winter 2017 to spring 2018. The ECLIPS 50 and TWINE SENSOR kits were used to monitor antibiotic residues in milk samples. The data were analyzed employing Chi-square test, using SPSS software version 20. The significance level was considered p<0.05. Results: In total, 100 raw milk samples were collected, of which 60 (60%) were from Beyza and 40 (40%) from Sepidan. A total of 95 samples (95%) were antibiotic-free and 5 (5%) contained antibiotic residual. 5 samples (5%) of ECLIPS 50 kit, 5 samples (5%) of TWINE SENSOR kit were shown to be positive, using both kits. Conclusion: There was no difference between ECLIPS 50 kit and TWINE SENSOR kits in detecting antibiotics residue in raw milk samples. The positive samples in the two sets of kits were identical. Furthermore, there was no significant difference between the two types of kits
