This study aimed to investigate the safety level of classrooms in Shiraz University of Medical Sciences.<br /> <strong>Methods:</strong> This cross-sectional study was conducted in Shiraz University of Medical Sciences (SUMS) classrooms (n = 63), in the south-west of Iran. Data regarding the safety measures were collected using an audit checklist. Finally, an index called Classroom Safety Requirement Index (CSRI) was introduced in order to calculate percentage of safety measures in the classrooms.<br /> <strong>Results:</strong> The results revealed that the ‘environmental condition’ dimension of the CSRI was in a good level. The ‘building’, ‘equipment’ and ‘electrical’ dimensions were in the medium level, and the ‘fire safety and emergency’ dimension was placed in the poor level. 38.70% of the classes (24 classes) were in the Standard Occupant Load (SOL or degree of overcrowding) and others (61.30% of classrooms) were overcrowded (unacceptable occupant load).<br /> <strong>Conclusion: </strong>The examined classrooms were very poor regarding the ‘fire safety’ and ‘emergency exit’, which requires proper and appropriate measures to improve safety in these areas.https://jhsss.sums.ac.ir/article_46195_73b3416b56981e53ae1787686f1d1446.pdfShiraz University Of Medical SciencesJournal of Health Sciences & Surveillance System2345-22186420181001Design, Construction and Evaluation of Local Exhaust Ventilation System for the Control of Total Dust and Crystalline Silica in a Tile Manufacturing Factory1651724619610.30476/jhsss.2019.83246.1020ENAbdorrezaZareiMSc in Occupational Health, Occupational Health Department, Health Faculty, Qom University of Medical Sciences, Yazd, Iran0000-0002-4649-6676MehdiJahangiriAssistant Professor of Occupational Health, Department of Occupational

The present study aimed to investigate the role of therapeutic alliance and group cohesion in group therapy based on mentalization and dialectical behavior in borderline personality disorder.<br /> <strong>Methods:</strong> This is a single-blind randomized controlled clinical trial conducted on 36 patients diagnosed with BPD (12 in each three groups). They were examined by a semi-structured clinical interview. Data were collected from March 2017 to June 2017. All screening and performance procedures were performed daily in Hefez hospital, Shiraz. Patients were selected through targeted sampling. Data were entered into SPSS, version 21, by using repeated measures and simple regression analysis and analyzed by one who was blind to the groups. The computer method was used for randomization. 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), Working Alliance Inventory (WAI), Group Cohesion Scale (GCS), Beck Anxiety Inventory (BAI), and Beck Depression Inventory-II (BDI-II) questionnaires.<br /> <strong>Results:</strong> After the intervention, therapeutic alliance (p=0.005) and group cohesion (p=0.0001) in both experimental groups had significantly higher scores compared to the control group.<br /> <strong>Conclusion:</strong> The two relationship elements were found to contribute to psychotherapy outcome. Therapeutic alliance and group cohesion had also been estimated to account for at least as much variance in psychotherapy outcome as specific therapeutic interventions.https://jhsss.sums.ac.ir/article_46198_13db1cfb6d1ea8e8f3d6c8697a829f0d.pdfShiraz University Of Medical SciencesJournal of Health Sciences & Surveillance System2345-22186420181001Investigation on the cytotoxicity and apoptosis of citrate based silver nanoparticles, in vitro1901974619910.30476/jhsss.2020.83344.1023ENLayaEbrahimiDepartment of Food Hygiene and Public Health, School of Veterinary Medicine, Shiraz University, Shiraz, Iran0000-0001-5514-5432SaeidHosseinzadehDepartment of Food Hygiene and Public Health, School of Veterinary Medicine, Shiraz University0000-0001-7691-6435MaryamPourmontaseriDepartment of Food Hygiene and Public Health, School of Veterinary Medicine, Shiraz University, Shiraz, Iran.JafarJalaeiDepartment of Food Hygiene and Public Health, School of Veterinary Medicine, Shiraz University, Shiraz, Iran.Journal Article20180706<strong>Background:</strong> 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.<br /> <strong>Methods:</strong> 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.<br /> <strong>Results: </strong>The present study showed a dose-dependent cytotoxicity of the silver nanoparticles with log IC<sub>50</sub> 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.<br /> <strong>Conclusion:</strong> Silver nanoparticles revealed cytotoxic effects on the Vero cells which was associated with the method of synthesis of silver nanoparticles.https://jhsss.sums.ac.ir/article_46199_c7ed36225f7c87073796eb8286193897.pdfShiraz University Of Medical SciencesJournal of Health Sciences & Surveillance System2345-22186420181001Interaction effects of sewage sludge and its biochar on anthracene biological degradation in a Pb polluted soil under sunflower cultivation1982064620010.30476/jhsss.2020.84355.1032ENAmir HosseinBaghaieDepartment of soil science, Arak Branch, Islamic Azad University, Arak, Iran0000-0002-8936-1202MohammadFereydoniDepartment of Soil Science, Arak Branch, Islamic Azad University, Arak, IranJournal Article20180701<strong> </strong><br /> <strong>Background: T</strong>his descriptive study was conducted to evaluate the interaction effects of sewage sludge and its biochar on anthracene biological degradation in a Pb polluted soil under sunflower cultivation<strong> </strong><br /> <strong>Methods</strong>: Treatments consisted of applying three rates of anthracene (0, 12.5 and 25 mg/kg soil), two levels of sewage sludge and its biochar (0 and 30 t/ha) in the presence of Azetobacter bacteria and Piriformospora indica (P. indica) fungus. After 60 days, plants were harvested and plant Pb concentration was measured using atomic absorption spectroscopy. In addition, the soil petroleum hydrocarbons concentration and soil microbial respiration were measured by the method described by Besalatpour et al. (2011). The catalyze enzyme activity was assayed.<br /> <strong>Results</strong>: Plant inoculation with P.indica and Azotobacter significantly increased the degradation of anthracene in soil by 12.8% in the soil treated with 25 mg anthracene/kg soil. In addition, the soil Pb availability was decreased by 14.6% in the mentioned treatment. Applying 30 t/ha sewage sludge and its biochar significantly increased the plant biomass and anthracene degradation in the soil treated by 12.5 mg anthracene /kg soil by 13.5% and 12.6%, respectively.<br /> <strong>Conclusion</strong>: Soil treated with sewage sludge and its biochar had a positive effect on plant resistance to abiotic stresses and degradation of anthracene in the soil. Among this, plant inoculation with P. indica and Azotobacter had also an additive effect on bio-remediation of anthracene in the soil that is a positive point in environmental studies. However, soil pollution with heavy metals had an adverse effect on it.https://jhsss.sums.ac.ir/article_46200_f6e53cb0d85bd220f12a8325976d803a.pdfShiraz University Of Medical SciencesJournal of Health Sciences & Surveillance System2345-22186420181001Assessment of anesthetist’s non-technical skills in Iranian hospitals2072114620110.30476/jhsss.2020.84392.1034ENMiladGholami1- PhD Candidate of Ergonomics, School of Public Health, Shiraz University of Medical Sciences, Shiraz, Iran0000-0002-0742-2631ZahraZamanianShiraz University of medical Sciences0000 0003 2462 2456RezaKalantari1- PhD Candidate of Ergonomics, School of Public Health, Shiraz University of Medical Sciences, Shiraz, Iran0000-0002-8938-2476MehdiHasanshahiDepartment of Operating Room, School of Nursing, Shiraz University of Medical Sciences, Shiraz, IranEsmaeilHosseinzadeh RoknabadiDepartment of Healthcare Management, School of Health Management & Information Sciences, Iran University of medical sciences, Tehran, IranSomayehGheysariDepartment of Operating Room, School of Nursing, Shiraz University of Medical Sciences, Shiraz, IranJournal Article20180720<strong>Background: </strong>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.<br /> <strong>Methods:</strong> 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.<br /> <strong>Results</strong><strong>:</strong> 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.<br /> <strong>Conclusion</strong><strong>:</strong> 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.https://jhsss.sums.ac.ir/article_46201_3e7c5db34302c14b574341cc42117a34.pdfShiraz University Of Medical SciencesJournal of Health Sciences & Surveillance System2345-22186420181001A survey of community knowledge and practices on malaria control with indoor residual spraying in Kazerun, south Iran2122174620210.30476/jhsss.2020.84862.1046ENSeyed AghilJaberhashemi1Department of Medical Entomology and Vector Control, School of Health, Shiraz University of Medical Sciences, Shiraz, Iran0000-0003-1223-5010Mohammad DjaefarMoemenbellah-FardResearch Center for Health Sciences, Institute of Health, Department of Medical Entomology and Vector Control, School of Health, Shiraz University of Medical Sciences, Shiraz, Iran0000-0003-1223-5010MousaKhosravaniDepartment of Medical Entomology and Vector Control, School of Health, Shiraz University of Medical Sciences, Shiraz, IranMojtabaNorouziInfectious Diseases Control Unit, Health Center, Shiraz University of Medical Sciences, Shiraz, Iran0000-0002-3642-4265HadiKalariDepartment of Medical Entomology and Vector Control, School of Health, Shiraz University of Medical Sciences, Shiraz, IranJournal Article20180725Objective: The main aim of this research is to investigate the knowledge, attitude and practice (KAP) on malaria control with respect to indoor residual spraying (IRS) in a community of Southern Iran.<br /> Introduction: Human malaria is an important vector-borne infectious disease in Iran. It remains endemic over most parts of the oriental region of Iran that is still in the pre-elimination phase without considerable drop in the proportion of malaria cases. <br /> Methods: This research was a cross-sectional household survey conducted in Kazerun, Fars province, Iran, to examine he malaria status and identify the parameters that obstruct the progress of the elimination phase. A standard questionnaire with 20 questions was provided to households including knowledge, attitude and practice categories. Sampling was then stratified to choose the samples in three rural foci of Kazerun.<br /> Results: The sex ratio of participants included 192 females (92.3%) and 16 males (7.7%), respectively. This community benefited mostly from acceptable literacy level. A strong association prevailed between the majority of respondents’ (88.5%) knowledge of fever and chills as the main symptoms of malaria and their literacy level. The majority (198, 95.2%) of volunteers declared that malaria disease was transmitted through the mosquito bites. In line with this study, literate persons have raised motivation and attitude to use bednets and keep themselves away from mosquitoes. These individuals cooperate perfectly with healthcare workers in malaria control program strategies (especially IRS).<br /> Conclusion: Comprehensive and synergistic measures are needed to be taken to manage malaria elimination strategy in Iran.https://jhsss.sums.ac.ir/article_46202_383719282b6cefc7ca40d8c1ce581488.pdf
