Background: The close relationship between diet and disease emphasizes the need for optimal diet evaluation. The aim of this study was to compare the efficiency by which each of Healthy Eating Index (HEI)-2010, Diet Quality Index-International (DQI), Mediterranean Diet Score (MDS), and Diet Diversity Score (DDS) evaluates the diet. Methods: In a cross-sectional design, 438 adults aged 20-50 years were recruited. Dietary intakes were assessed using a semi-quantitative food frequency questionnaire. HEI-2010, DQI, MDS, and DDS were calculated and scored according to their corresponding criteria.Results: Energy (1917 ± 554 kcal to 2898 ± 933 kcal), saturated fats (17.0 ± 6.8 g to 28.1 ± 11.5 g), and cholesterol (244 ± 195 g to 414 ± 343 g) increased across tertiles of DDS and energy (2017 ± 699 kcal to 2621 ± 748 kcal) increased across tertiles of DQI. In contrast, saturated fats decreased (23.9 ± 12.0 g to 20.8 ± 8.1 g for HEI-2010 and 23.7 ± 10.0 g to 20.5 ± 10.4 g for MDS), but energy and cholesterol did not change significantly across tertiles of HEI-2010 and MDS. Other nutrients either did not change or changed appropriately across tertiles of the different indices.Conclusion: DDS and, to a less extent, DQI may not be good indicators of healthy diet especially in terms of obesity and cardiovascular diseases.

Background: The occurrence of heavy metals in the environment is of important concern due to their toxicity and health effects on humans, including cancer. Because metals have been extensively used for centuries in commerce, environmental contamination is widespread; moreover, exposure to metals and metal compounds continues to be a significant public health problem. Electroplating sludge contains heavy metals. Solidification/Stabilization can be used to avoid leaching of these metals to the environment. The aim of this study was evaluating the effectiveness of the application of dicalcium phosphate (DCP) and sodium tripolyphosphate (STPP) on Cd, Co, Cu, Ni, Pb and Zn immobilization in dewatered metal plating sludge.Methods: The ratios of STPP and DCP per dry plating sludge were determined to be 0.1%, 0.2% and 0.5% by weight. Metal leaching from the solidified plating wastes was assessed using the toxicity characteristic leaching procedure (TCLP). The results showed that the concentration of metals in untreated sludge were appropriate to classify this sludge as a hazardous waste as described in The Code of Federal Regulations (CFR) 40 CFR 261.24.Results: DCP and STPP lowered the concentration of metal in the effluent. Increasing DCP concentration from 0.1 to 0.5% decreases the contaminant concentration in the effluent. F or Cd, Pb, Cu and Ni increasing the percentage of STPP in the sludge increases the contaminant’s concentration resulting from TCLP extraction.Conclusion: Immobilization of heavy metals was more effective through application of DCP rather than STPP. Moreover, it may minimize the potential risk of groundwater eutrophication connected with the application of highly soluble phosphate like STPP.

Background: Although sleeping problems are common among all age groups, the elderly suffer a higher prevalence of sleep disorders. The present study aimed to investigate the relationship between sleep quality, self-efficacy, and stages of change among the elderly. Methods: This descriptive-analytical study was conducted on 36 individuals aged 60-75 years selected through simple random sampling in 2013. The data were collected using Pittsburgh Sleep Quality Index (PSQI) and self-made structured questionnaires, including sleep self efficacy scale and stages of sleep behavior change scale. SPSS statistical software, version 19 was used to analyze the data and descriptive and inferential statistics such as independent samples t-test were used. Results: The results of the present study revealed that the mean of sleep quality was 7.91 (SD=4.99). In addition, most of the subjects (69%) had poor sleep quality. Considering the stages of change, the participants were in different stages of sleep behavior change. Moreover, a significant relationship was found between self-efficacy and PSQI total score (P<0.001). Also, significant relationships were observed between self-efficacy and the variables of stages of change (P<0.05), except for the average night sleep. Conclusion: The results of this study showed that most of the elderly had poor sleep quality. Besides, they were in different stages of change in sleep problems. The results also indicated that self-efficacy affected the sleep quality in the elderly. Therefore, measures should be taken based on stages of change and increased self-efficacy to improve sleep quality among the elderly.

Background:Patient satisfaction is an integral component of service quality and obtaining feedback from patients about the quality of primary health care is the best way to extend more patient-centered goals to health care delivery. This study was conducted to measure the level of client satisfaction with Urban Family Physician and Referral System (UFPARS) programMethods: This repeated cross-sectional study was done in Fars province, South of Iran, at two sections. Totally, 5901 patients in two sections (6 and 24 months after the UFPARS startup) were selected using multi-stage random sampling. The participants answered a self-administrated questionnaire. We measured the client satisfaction using 5-point Likert-scaled score and combined the questions; for each component of UFPARS, 6 satisfaction dimensions were made. We compared the participants’ level of satisfaction in two parts, using t-test.Results: Reliability was acceptable, and equal to 85% or more in all domains .In all components of UFPARS, the mean client satisfaction score was higher than 3 out of 5. The lowest client satisfaction scores were seen in the outpatient services. In three components of UFPARS including enrolment, family medicine and para-clinics, the mean satisfaction scores significantly decreased (P<0.001) between the two sections. But other components showed no significant change. Conclusions:The level of satisfaction with UFPARS in Fars province was shown to be relatively medium to high. Low client satisfaction between the two sections could be a bad sign and we recommend that the problems should be tackled gradually. Although family physician program in Iran has some limitations, implementing this plan step by step can lead to a medical reform in Iran. We can develop better programs based on the comments from service recipients, and prompt the project and some program processes.

Backgrounds: Anxiety and depression are found to be the major contributors to irritable bowel syndrome (IBS). The present study aimed to measure the effect of a specifically designed cognitive behavioural therapy (CBT) program on the severity of the symptoms and quality of life of patients with chronic IBS, and also define whether anxiety and depression in patients with IBS at baseline affect their response to CBT. Methods: The participants were randomly allocated to conventional treatment only (n=25, control) or CBT plus conventional treatment (n=25, intervention) group. The intervention group attended an eight session group stress management training course conducted by a psychologist in a meeting room at a gastrointestinal clinic at Yasuj University of Medical Sciences. Pre- and post-interventions and 3-month follow-up visits were scheduled and conducted by an experienced healthcare worker to measure the primary outcomes and levels of depression and anxiety in the patients. The study was conducted on 2011. Results: The Raw Group Difference (RGD) and Standardised Mean Differences (SMD) for the post-treatment scores of the intervention group, when compared with those of the control group, indicated a considerable improvement in the severity of IBS symptoms (RGD=−10.48, SMD=−1.23), anxiety (RGD=−9.90, SMD=−0.725), d epression ( RGD=−9.57, SMD=−0.785) a nd patient’s quality of life (MD=−16.81, SMD=−0.469). No association (and interaction with CBT) was found between anxiety/depression at baseline and post-treatment or follow-up scores of the outcomes. Conclusion: Although CBT improved anxiety, depression, severity of IBS and quality of life of patients with IBS, its effect was independent of the initial level of anxiety and depression of the patients.

Background: Dialectical Behavior Therapy (DBT) and Metalization-based Treatment (MBT) are two approaches to the treatment of Borderline Personality Disorder (BPD). The present study aimed to investigate the clinical outcomes of dialectical behavior group therapy and metallization-based group therapy on reduction of the severity of symptoms in patients with BPD. Methods: This is a single-blind randomized controlled clinical trial conducted on 36 patients diagnosed with BPD by a psychiatrist. They were examined by a semi-structured clinical interview. Data were collected from March 2017 to June 2017. The participants were categorized into intervention and control groups. Before, immediately and two months after the intervention, the participants filled out the Borderline Personality Disorder Severity Index (BPDSI), Beck Anxiety Inventory (BAI), and Beck Depression Inventory-II (BDI-II) questionnaires. Results: The two group therapy based on MBT and DBT were effective in reducing the symptoms of borderline personality disorder equally (p=0.4). Both treatments were more effective than the control group receiving only medication (p <0.001). This improvement was persistent two months after the intervention (p <0.001). Conclusion: The results of the study revealed that group psychotherapy based on metallization and dialectical behavior combined with pharmacotherapy is considerably more effective than treatment with pharmacotherapy. Metallization can be a common factor in any successful treatment of BPD.

Background:Free Living Amoebas, as opportunistic protozoa, can cause more problems such as meningoencephalitis, encephalitis and keratitis in human being. These protozoa have been isolated from many sources in Iran. This study was undertaken to determine the diseases due to these parasites in the south of Iran. Methods: In this cross-sectional study, 200 cerebrospinal fluid (CSF) samples and 15 corneal scrapings were collected from patients admitted in clinics of Shiraz city. The samples were examined by light microscopy, cultivation and molecular methods. Phylogenetic relationship was also conducted among the sequences and various Acanthamoeba spp. based on nucleotide sequences in NCBI GenBank. Results: No infection in CSF samples was seen, while one patient suspected with keratitis was positive to Acanthamoeba sp. infection only by PCR. Using Sequencing technique and Phylogenetic tree, the genotype of the parasite was demonstrated T4. This sample belonged to a 26 year old woman who used a contact lens. Conclusion: Our results indicate that it is necessary to pay attention to the complexity of the free living amoeba infections, especially in soft contact lens wearers. Also, PCR as an appropriate method in diagnosis is recommended for the detection of free living amoebae. However, it is unavoidable to suspect these protozoa as an infectious agent in patients with central nervous system infection due to increased immunodeficiency disorders.

Background: Heavy metals have destructive and irreversible effects on the human, plants and animals. Some industries in Yazd enter industrial wastewater to municipal wastewater collection system. This can lead to high levels of heavy metals in wastewater and in turn in the wastewater treatment plant effluent. Methods: This study was carried out during four months from December 22, 2009 to May 20, 2010. The experiment was performed on the inflow, outlet of anaerobic pond and first and second facultative ponds of wastewater treatment plant and then transferred to the laboratory and measured by atomic absorption spectroscopy. Results: The results of the experiments showed that the average cadmium concentrations in the inflow, anaerobic pond outlet, and first and second facultative pond outlet were 0.0066, 0.0087, 0.0076, and 0.0083μg/l, respectively. The average amounts of chromium in the inflow, anaerobic pond outlet, and first and second facultative pond outlet were 0.0076, 0.0065, 0.0043, and 0.0056 μg/l, respectively. Cadmium concentration in the effluent was higher than standard. Conclusion: The comparison of the obtained data with Iranian standards for wastewater treatment for reuse in irrigation shows that the cadmium concentration exceeded the standard and the chromium concentration was lower than the standard. Therefore, it is not suitable for reuse in the crop farms and aquatic life.

Background: This study aimed to determine the efficiency of the intermittent cycle extended aeration system (ICEAS) and the removal conditions of treating contaminants, especially nitrogen phosphorus from sea shopping center wastewater.Methods: Experiment was carried out on fish distribution center of Bandar Abbas and 30 samples were collected in a 6 month period from the inlet of the market septic tank. The used pilot study carried out consisted of two zones: pre-react and main react zones. They were divided using a baffle wall. Firstly, wastewater enters a pre-react zone and then through the opening at the bottom of the baffle wall it enters the main react zone. The experiment was carried out with three simultaneous cycles per day.Results: The results showed that the mean of BOD5, COD, phosphorus, and nitrate and nitrite removal was 91.5, 86.7, 59.5, 49, and 80.8 percent, respectively.Conclusion: It was shown that the system is able to remove nitrogen and phosphorus almost similar to other proprietary phosphorus removal processes and with lower cost; however, it is not a proprietary process.

Background: Among Alkanes, N-Alkanes with medium chain have been identified as the most important contaminants of the soil. N-hexadecane (C16H34) with low solubility in water also belongs to this group and has been used by many researchers as a model contaminant. The present study aimed to investigate the effect of the external source of carbon (glucose) as co-substrate on removal of hexadecane from the soil.Methods: In this study, a Slurry Sequencing Batch Reactor (SSBR) was used as a pilot by a bacterial consortium, including bacterium Acinetobacter radioresistens, Bacillus subtilis, and Pseudomonas aeruginosa, in order to remove different concentrations of hexadecane (1,4,7, and 10 percent).Sampling was performed four times during the sedimentation step. Then, the samples were analyzed by GC-FID and the results were analyzed statistically.Results: The results showed that hexadecane removal (%) by the microbial consortium was higher in lower initial concentrations in such a way that the biological removal of hexadecane was respectively 45.95%, 38.55%, 34.39%, and 32.40% in the concentrations of 1%, 4%, 7%, and 10% on the third day. Moreover, adding the external carbon source (glucose) on the first day caused a 16% increase in hexadecane removal, which is 1.4 times more than the amount of hexadecane removal in the conditions without co-metabolism.Conclusion: The results showed that SSBR could be used as an exit-situation effective method for hexadecane removal in low concentrations through considering the effective factors in its function, such as dissolved oxygen, pH, and temperature. Also, adding the secondary carbon source could be effective in hexadecane removal from the soil. Yet, this effect might vary on different days.

Background: The present study aimed to investigate the effects of work shifts and mental workload on chronic fatigue among female nurses in Intensive Care Units of selected hospitals in Shiraz. Methods: The participants in this cross-sectional study were 118 female nurses working in Intensive Care Units of three hospitals in Shiraz with an average age of 304.8± years. SP (Samn-Perelli) Mental fatigue scale and NASA task load index were rated for two weeks at the beginning and end of each work shift. The Checklist Individual Strenght (CIS) questionnaire was completed to assess the fatigue during the last two weeks. Results: Mean score of chronic fatigue was 69.2±13. Menal fatigue and mental workload per shift were significantly correlated with work shifts (P=0.001). Mental workload (P=0.006, r=0.24) and mental fatigue caused by work shifts (P=0.001, r=0.42) were also significantly correlated with chronic fatigue. Conclusion: The results of the study showed that mental workload and work shifts influence the nurses’ fatigue in Intensive Care Units. Therefore, using intervention strategies to reduce mental work load and modification of shift work system in this group seems to be necessary.

Background: Among chemical dyes, Azo dyes, as environmental synthetic pollutants, are most commonly used in a bunch of different colors in different industries, especially in textile industry to a large extent. Methods: Due to some limitation and difficulties to remove these pollutants from the environment, the biological filtering method, as the economically and optimal methods, are preferred. Using the Taguchi method and evaluation of such factors in the environment as temperature pH, color density and concentration of salt, we studied the optimal condition of Halomunas PTCC1132 bacteria decolorization in order to compare it with the Aryapress dye removal from aquatic environment. Therefore, 16 experiments were designed according to Array Table in 4 factors and 4 levels. The results were then analyzed using a computer the program named Qualitek-4. Results: The results showed that this salt, loving bacterium Halomonas strain PTCC1714, has the ability of bleaching in a wide range of salts till 20%, pH (5-9) and dye tolerance up to 5 gr/lit (500 ppm), and has the highest rate of decolorization in 100 ppm. Conclusions: According to the results with an optimal growth condition- the temperature of 40c, pH of 7.5, and the salt concentration of 10% up to 93% - the strain was capable of removing the Azo dye Aryapress color with the concentration of 100 ppm which is a considerable amount and can be used in biological treatment of industrial textile sewage.

Background: Today, the quality of life (QoL) studies have an important role in public health care, especially among the old adults suffering from chronic diseases such as diabetes. Diabetes and its complications can widely affect various aspects of QoL. Therefore, the present study aimed to assess diabetic patients’ QoL and identify the factors that affect it. Methods: A cross-sectional study was conducted on 593 randomly selected diabetic patients aged 60 years and above who were admitted in 13 diabetes clinics in Shiraz, Iran, in 2014. Diabetes Quality of Life-Brief Clinical Inventory (DQOL-BCI) questionnaire was used to assess the quality of life in these patients. Univariate and multivariate linear regression analyses were performed, using Stata software, version 12, to identify the predictors of DQoL. Results: The participants’ mean DQoL score was 41.8±6.2 with a mean age of 66.2±6.0 years. Multivariate linear regression analyses revealed that FBS level (115-180 mg/dL: P=0.05; above 180 mg/dL: P=0.02) and duration of diabetes (4-9 years: P=0.06; above 9 years: P=0.002) were two important clinical predictors of DQoL. Conclusion: This study demonstrated a relationship between clinical and socio-demographic factors and diabetic patients’ QoL. Considering these related variables could lead to effective control of diabetes complications and improvement of the patients’ QoL.

During the last two centuries, human being has emitted huge amounts of greenhouse gases to the atmosphere, by providing energy from fossil fuels. The increasing accumulation of these gases in the atmosphere has led to "global warming" and as a result "climate change". This inauspicious phenomenon has such a wide domain that threat the survival of the human around the world. The sharp decline in fresh water sources and strategic agricultural products and severe destruction of environment are just some inevitable adverse effects of climate change. Therefore, it would be a proper ground for breaching some of the most important human rights. The aim of this research is to show effects of climate change on "right to health" and some other related rights, and therefore responsibilities of governments to fight against that. Conclusion: Climate change due to human activities, makes a proper field for breach of human rights globally, and as we see "right to health" is affected absolutely. According to principal of "common but differentiated responsibilities", most of the burdens of combating against climate change are on the shoulders of developed states and developing countries have much less obligations; but at least have common responsibilities. Rather, all of the states have clear international obligations for protecting human rights in their territories. Therefore any state must separately or together with others, take urgent and also long term measures to fight this phenomenon. If climate change continues; negligence of states in performing due diligence in this regard may lead to their international responsibility or even their incapability for governing the state in accordance with "good governance principles".

Background: Although medical errors in the clinical system are a common cause of lawsuits against physicians, ethical violations have been reported at an alarming pace. We conducted this study to determine the frequency of ethical issues related to patientphysician relationships in registered complaints in three teaching hospitals in Kerman, Iran, from 2015 to 2018.Methods: In this cross-sectional study, we extracted data from all complaint cases registered in the complaints offices. The data were categorized according to ethical issues in the physicianpatient relationship including breaching confidentiality, not telling the truth to the patient, not obtaining informed consent, abandoning further treatment, causing unnecessary expenses, violating privacy, and not respecting the patient; then, we compared them according to our objectives using SPSS software.Results: The results showed that 51.7% of the physicians who had been sued were male, and 30.2% of all of them were general surgeons. The most common ethical issues were related to not respecting the patient (49.7%), abandoning further treatment (25.5%), not telling the truth to the patient (14.1%), and not obtaining informed consent (5.4%).Conclusion: The complaints received in three teaching hospitals can reveal the disregard for ethical codes, and irresponsible behavior among healthcare providers may endanger the patients’ safety and increase the likelihood of injury in these hospitals. Further studies are recommended to determine the factors that influence ethical violation in the healthcare setting.

Background: High amount of heavy metals in sludge is one of the major obstacles to its use on farms. The present study aimed to investigate the possibility of leaching heavy metals from wastewater sludge by Fenton method and determine the optimum level of parameters, such as iron, hydrogen peroxide, time, and pH for Fenton reaction. Methods: The effects of various parameters, such as pH (2-9), hydrogen peroxide concentration (0.5-6 g/l), Fe concentration (0.5-4 g/l), and leaching time (5-60 min), were studied. Results: The results showed that the optimal condition for leaching of heavy metals occurred at pH of 2 3, hydrogen peroxide concentration of 3 g/l, iron concentration of 2 g/l, and leaching time of 15 min. Under these optimal conditions, 92% of Zn, 100% of Cd, 100% of Pb, and 80% of Cu were leached from the wastewater sludge. Conclusions: Fenton method can leach heavy metals from wastewater sludge through decomposition of organic materials at H2O2/Fe ratio of 1.5:2.

Background: The Prangos ferulacea (PF)–yogurt is a traditional food in Iran. This study investigated the effects of PF on the microbial, physicochemical and sensory properties of probiotic yoghurt.Methods: Pasteurized low fat milk was heated up to 85°C, cooled to 40°C, and then mixed with conventional and Lactobacillus casei starter cultures incubated at 37°C until pH decreased to 4.6. Then, the cooked PF was added to yogurt and stored at 5°C for 21 days. Acidity, Syneresis, probiotic colony count and sensory evaluation of yoghurt was determined during the storage time. The experiments were replicated for three times. Probiotic yogurt (PY) was examined as the control and probiotic yoghurt containing 10, 20 and 30% Prangos ferulacea (PFY) as the samples.Results: Total titratable acidity of PFYs compared to PY was not significant during 21 days. The syneresis rate of PFY yogurt showed significant differences compared to PY during storage time (P<0.001). Comparison of the mean scores of sensory attributes (taste, odor, syneresis, mouth feel and color) of PFY yogurt showed that there were no significant differences with PY. Enumeration of lactobacillus casei (logCFU/mL) revealed significant differences in PFYs compared to PY in each experimental day (P=0.040). At the end of the storage time (day 21), the highest number of L.casei was observed in PY and PFY 20% and the lowest in PFY30%.Conclusion: Adding Prangos ferulacea (20%) to probiotic yogurt prevented an increase in acidity, a decrease in syneresis rate and an increase in the number of probiotic bacteria during 21 days. Results showed that the highest number of probiotic bacteria was seen in probiotic yogurt containing 20 percent Prangos ferulacea; probably, the existing fiber and some nutrients in Prangos ferulacea promoted the viability of probiotic bacteria.

AbstractBackground: Proper weight gain is essential for the mother’s health and pregnancy. On the other hand, insufficient weight gain is directly related to a decrease in the growth and preterm birth. The present study aimed to determine the relationship between the mother’s Body Mass Index (BMI) and pregnancy and delivery outcomes in mothers referred to Gerash health centers in 2014.Methods: This retrospective, cohort study was conducted on the data from 554 pregnant mothers referred to Gerash health centers to receive pregnancy healthcare from April to November 2014.Results: The mothers’ mean age was 25.9±5.4 years and their mean weight gain was 11.6±4.0 kg. In addition, 62.6% and 37.5% of the babies were born through natural delivery and cesarean section, respectively. About 9% of the children were pre-term, while 91% were term and post-term. Besides, 5.4% and 5.1% of the mothers got gestational diabetes and anemia, respectively. The results of logistic regression analysis showed positive relationships between the type of delivery and BMI (OR: 1.10(95% CI: 1.05-1.14)), history of cesarean section (OR: 0.02(95% CI: 0.01-0.07)), and mother’s age (OR: 1.06(95% CI: 1.03-1.10)) (p<0.05). Moreover, a positive relationship was found between the gestational weight gain and infant’s birth weight (g) (OR: 18.42(95% CI: 8.02 – 28.82)) (p<0.05).Conclusion: According to the finding, it seems that it would be necessary to plan educational and counseling programs before the pregnancy for the mothers. Therefore, the role of health authorities is more important than ever in promoting the general knowledge to reach the proper weight before and during pregnancy.

Introduction: The role of fathers in adolescents’ health is regarded as less important than mothers. This necessitates considering their role more than before. The present study was conducted to investigate the associations between high school students’ demographic profile and their general health with the fatherhood characteristics of their fathers. Methods: This descriptive-analytical and cross-sectional investigation was conducted among 604 girl and boy students in 2015 in Shiraz (Iran). The data collection tools included two self-administered questionnaires and a General Health Questionnaire (GHQ). Two self-administered questionnaires consisted of 5 demographic and 16 fatherhood characteristics questions. They were selected through a simple random sampling method, and the data were analyzed by Pearson correlation and descriptive statistics. The significance level was considered as 5%. Results: The findings showed that 495 students (46.90% girls and 53.10 boys) participated in the present study. They also demonstrated that 382 students were between 15-17 years old (79.20%) and 113 of them (20.80) aged about 18-19. There was significant associations between the mean scores of students general health and some of their fatherhood characteristics (P value=0.01). Some of their demographic information was also correlated to their general health significantly. The mean scores of fatherhood characteristics and students’ general health were, in turn, 38.56 (SD=14.6) and 44.99 (SD=9.69). Conclusion: This study demonstrated the role of fathers in their offspring’s health status. It makes it necessary to educate fathers and reinforce their capabilities to promote their children’s health.

Background: With the advancement of nanotechnology, nanoparticles have been applied in our modern society. However, the hazardous effects of nanoparticles on organisms have not been thoroughly clarified yet. Considering the migration of nanoparticles in food and its subsequent consumption by humans, we have employed normal cell line, the African green monkey kidney cell line (Vero) for evaluation of the cytotoxic activity of the silver nanoparticles. Currently, there are various approaches to perform toxicity tests. In this study, we investigated the effects of citrate-based silver nanoparticles on Vero cells to explore the adverse effects of these nanoparticles. Methods: In an experimental work, to synthetize silver nanoparticles, silver nitrate and citric acid were used. Nanoparticles were further characterized by UV-Visible Spectroscopy, Dynamic Light scattering (DLS) and Scanning Electron Microscopy (SEM). Cells were exposed to various concentrations of the nanoparticles (1.56 to 1000 µg/ml) for 24 h and 48h. The cytotoxic activity and apoptosis were determined using MTT assay and acridine orange/ethidium bromide (AO/EB) staining, respectively. Results: The present study showed a dose-dependent cytotoxicity of the silver nanoparticles with log IC50 values of ~ 10.68 and 2.06 µg/ml for 24 h and 48 h, respectively on Vero cell lines. Analysis by AO/EB staining indicated that the silver nanoparticles induced apoptosis in the cell lines. Conclusion: Silver nanoparticles revealed cytotoxic effects on the Vero cells which was associated with the method of synthesis of silver nanoparticles.

AbstractBackground: The reduction of suicidal attempts as one of the most important goals is improvement of societies’ health status. The present study aimed to assess the epidemiologic aspects of suicide cases in Fars province in 2010-2011.Methods: A total of 9714 suicide cases in Fars province, south of Iran, in 2010-2011 were enrolled in this cross-sectional study through census. The study data were collected using suicide registry forms in the health centers affiliated to Fars province department of health services and analyzed using SPSS, version 17.Results: The rate of suicide attempts was 116.5 per 100,000 population in Fars province (93per 100,000 among men and 141.5 per 100,000 among women). The results showed significant differences between the suicide rates based on sex, age group, place of living, and season of the year (P<0.001). Most of these cases were female (59.4%), single (52.9%), 15-24 years old (56.4%), had high school education (25.8%), lived in urban areas (69.6%) and were female homemakers (30.3%). Based on the data, however, the largest number of suicide deaths resulted from self-immolation (56.7%).Conclusion: The present study findings revealed different rates of suicidal attempts based on sex and age group. Also, the importance of education and mental support, especially among women and singles, and also preventive measures in the context of uncontrolled immigration from the countryside to the large cities seems to essential more than ever. Yet, defects in some findings, particularly information about etiology, suggest that more researches should be conducted and suicide data registry and reporting systems should be improved.

Background/Objective: Musculoskeletal disorders (MSDs) are one of the most common causes of occupational injuries. This study was conducted with the objectives of determination of prevalence rate of MSDs and ergonomics assessment of the risk of MSDs among workers of a petrochemical company. Methods: In this study, 261randomly selected workers in a petrochemical company with at least one year of job tenure participated. Office and operational personnel were studied separately. In office jobs, data were collected using Nordic musculoskeletal disorders questionnaire (NMQ) and ergonomics checklist for assessment of work conditions. In operational jobs, NMQ and QEC (Quick Exposure Check) methods were applied to gather the required data. Data analysis was performed using SPSS software. Results: The most prevalent MSDs symptoms were reported in the lower back (36.2%), upper back (31%), neck (31%) and knees (30.3%). The results showed that the prevalence of MSDs indifferent body regions of the office staff was higher than those of operational workers. Also, in 40.9% of the observed cases, total ergonomics index was in action category 1 (inappropriate working conditions) and 59.9% of the subjects taken in action category 2 (appropriate working conditions). The results of assessment by QEC technique among operational workers showed that in 82.8% of the workers studied, the level of exposure to musculoskeletal risks was high or very high. Conclusions: The prevalence of musculoskeletal disorders in the office staff was higher than that of operational subjects. To improve the working conditions, taking risk factors of the lower back, upper back, neck and knees into consideration seems to be essential.
