Introduction: Regarding the association between climate, seasons and myocardial infarction, a cross-sectional study was carried out in Shiraz and Bandar Abbas in Iran.Methods: All patients with diagnosis of acute myocardial infarction living in Shiraz and Bandar Abbas were included in the study during 2011-2013. Demographic data were extracted from the patients’ hospital records. Data were analyzed using descriptive statistics, student’s t-test, and Chi-square test with SPSS software.Results: A total of 2626 patients were admitted with acute myocardial infarction of which 1546 were from Shiraz and 1080 from Bandar Abbas. Admission rate due to myocardial infarction was 0.12 in Shiraz and 0.24 in Bandar Abbas. In Shiraz, 35.2% were female and 34% in Bandar Abbas, Mean age of female patients was 65.68 years in Shiraz and 62.46 in Bandar Abbas while mean age of male patients in Shiraz was 60.39 years and 57.22 years in Bandar Abbas. Difference of admissions in 4 seasons was statistically significant in Shiraz, but not significant in Bandar Abbas (P>0.05). Seasonal variation of myocardial infarction had no correlation with gender or age of the patients.Conclusion: Incidence of myocardial infarction in Shiraz was half of the incidence rate in Bandar Abbas. In summer of low altitude humid areas, extra healthcare should be provided to high risk patients with coronary artery diseases, whereas this caution should be taken in high altitude areas with cold winter to minimize incident of myocardial infarction.

Introduction: The aim of this study was to investigate the structural changes of cardiac tissue in response to L-carnitine supplementation and endurance training in Wistar male rats toxicated by steroid anabolic hormone.Methods: 36 male Wistar rats aged 8-12 weeks (weight 195±7.94g) were randomly divided into six groups: Control, Non-treated, Boldenone (5 mg/kg), L-carnitine (100 mg per kg), Endurance Training-L-carnitine and Sham group. Injection was conducted deep in the hamstring once a week on an appointed day. The endurance training Protocol with moderate intensity (50-55% maximal oxygen consumption) was performed for six weeks and five times a week. After anesthesia, autopsy was performed and the cardiac tissue was isolated.Results: The results showed that boldenone causes damage to the heart tissue muscle and heart muscle cells. Also, boldenone caused mild necrosis and congestion in the heart tissue. However, the results showed that L-carnitine supplementation with endurance training can decrease to normal levels and damage the heart tissue muscle and heart muscle cells.Conclusion: According to the findings, it seems that boldenone causes some structural changes in the heart tissue, and possibly endurance training with L-carnitine supplementation can reduce these changes.

Introduction: Acute myocardial infarction (MI) indicates irreversible myocardial injury resulting in necrosis of a significant portion of myocardium. MI is associated with high mortality. The difference between the signs of MI in each gender is unclear. The aim of this study was to describe gender-associated differences in symptom presentation after acute MI.Methods: This analytic-descriptive research was carried out on 102 patients (44 women and 58 men) with MI experience who referring in Shahid Mohamadi hospital and Abolfazl hospital, Hormozgan, Iran. Patients participating in the study were randomly selected. Individual information; the pain characteristics records, electrocardiogram and laboratory results, pain numerical rating scale, were collected.Results: The results showed that chest pain was the most common initial symptom in both men and women (92%) This is while sweating in men (74%) and dyspnea in women (61.4) as the second reported sign. No gender-related differences in other symptoms such as vomiting, nausea, dizziness, palpitations, pallor, epigastric pain, chills and weakness were observed.Conclusion: In this study in patients with MI, women had a worse-risk profile in comparison to men. No significant gender-related differences in symptoms were observed.

Introduction: Despite benefits in the treatment of most autoimmune and inflammatory diseases, glucocorticoids (GCs) have proved side effects including hypertension, diabetes, osteoporosis and lipid disorders. Determining the risk factors for hypertension can facilitate the identification of high-risk individuals and lead to effective control of the side effects. The present study aimed to determine the risk factors for hypertension in individuals receiving high-dose GCs.Methods: This prospective study recruited 140 adults (age>18 years) requiring prednisolone or equivalent more than 30mg daily for at least three months. The participants’ blood pressure was monitored every month and correlations between the incidence of hypertension and variables such as serum calcium levels, weight, underlying diseases, body mass index (BMI), and folic acid use were investigated by repeated measure analysis.Results: While none of the subjects were hypertensive at baseline, 55 patients (39.28%) developed hypertension during the course of the study. Baseline weight and BMI, cumulative GC dose, family history of hypertension, and age were significantly higher in hypertensive patients.Conclusion: High BMI, male gender, elderly, family history of hypertension may have impact on development of hypertension in patients taking GCs.

Introduction: Toxoplasmosis is a widely prevalent zoonotic disease, caused by T. gondii. Chickens, consumed widely in many countries, are considered as one of the most important hosts in the epidemiology of T. gondii infection because they could be a main source of infection for both cats and humans. There was no information regardingT. gondii infection in chickens in this area, therefore, this investigation carried out to determine the prevalence ofT. gondii infections in poultry in Hamadan.Methods: A total of 203 birds including free-ranged, caged chickens and 2 turkeys were studied. The poultries' sera tested by indirect hemagglutination test (IHA) forT. gondii antibody. The birds' brain tissue used for testing forT. gondii tissue cyst. Brain of each bird grinded and suspension were made by normal saline and inoculated to peritoneal cavity of five mice. Peritoneal aspirate examined for tachyzoites after 5-10 days. Data regarding kind of bird, age, gender and raising type were recorded and analyzed.Results: Tissue cyst of T. gondii was detected by bioassay in the brain of 3 out of the 203 samples (one FR and one caged) by peritoneal inoculation (1%). Seropositivity forT.gondiiantibody was 6.1% (12.196). Positive cases were 6 FR hens, 1 caged chicken and 5 roosters. No positive case found in the turkeys.Conclusion: This study indicates that, both FR and caged chickens may have similar risk of infection toT. gondii and can transmit the parasite to humans.

Introduction: Quality and knowledge-based human resources are the most important competitive advantage and the scarcest source in today's knowledge-based economy.Hence, the development of the capabilities, expertise, and commitment of well-trained employees is considered the most important management challenge in our time. The present study was conducted to investigate the role of Management Succession Planning (MSP) in human resources talent identification and empowerment of human capitals in Hormozgan University of Medical Sciences.Methods: The present study is descriptive-analytic. The population studied was all the staff of Hormozgan University of Medical Sciences. Demographic information Mishra and Spritzer's empowerment, and Oehley's talent management questionnaires were used for MSP data. Finally, the data were analyzed using t-test, and regression analysis.Results: The results show a positive and significant correlation between MSP and talent identification of the University of Medical Sciences. There is also a significant and positive correlation between MSP and human capital empowerment of the University of Medical Sciences (0.43). Based on these results, with each unit of change in the variance of talent identification, 0.18 change occurs in the variance of MSP score; and with each unit change in empowerment variance, 0.27 change occurs in the variance of MSP score.Conclusion: It seems that systematic MSP is one of the requirements of the management system of Hormozgan University of Medical Sciences. Potential managers need to work along current experienced managers to take steps in empowering human capitals of the university by establishing a decent performance assessment system.

Introduction: The aim of this study was to evaluate the effects of aerobic exercise and pomegranate extract on antioxidant markers in women postmenopausal with type 2 diabetes.Methods: The statistical population of this study was the postmenopausal diabetic women of Babol City, North of Iran, who were referred to the Diabetes Association of the city.Among them, 33 subjects were selected randomly and divided into four groups: Control-Water (CW), Control-Pomegranate extract (CPE), Training-Water (TW) and Training-Pomegranate extract (TPE). The experimental group training plan consisted of 6-week aerobic exercise training, three times a week for at least 45 minutes per session.Consumer groups of pomegranate extract drank 150 ml of pomegranate extract every day for 6 weeks. Before and after this interventional study, blood sampling was performed from the brachial vein in a sitting position in a fasting state. The antioxidant markers of GPX, SOD, GSH and TAC were measured in the specimens.Results: The results showed that aerobic exercise training with the consumption of pomegranate extract significantly increased the levels of glutathione peroxidase and superoxide dismutase, plasma glutathione and Total Antioxidant Capacity (TAC) in women with type 2 diabetes compared to the control group (P<0.001). Women with type 2 diabetes in Training-Pomegranate extract groups had the highest levels of the antioxidants.Conclusion: Our finding showed that aerobic exercise training associated with the consumption of pomegranate extract improve the body's antioxidant defense system by increasing the levels of plasma antioxidants.

Introduction: Most modern medical issues are inherently complicated and accurate decisions are not always likely to be made based on logical reasons. Furthermore, the huge volume of information relevant to a simple diagnostic area makes this decision making even more troublesome. Hence, with the advent of technology, there is an ever increasing need for the Clinical Decision Support System (CDSS) in hospitals. This study has been conducted in an Iranian hospital with the aim of identifying the most significant barriers for implementing CDSS and suggesting appropriate strategies to remove them.Methods: This qualitative cross-sectional study was conducted in 2015. The sample population of the study included 180 physicians and nurses in Shahid Mohammadi hospital in Bandar Abbas whose performance was changed using CDSS. The participants were selected using stratified sampling from 23 different wards in the hospital. First, the barriers and strategies for implementation of CDSS in other countries were extracted from a review study which was used to make a preliminary model. Then, the results of a questionnaire and Delphi tests in three rounds were included in the final model.Results: The most significant barriers in implementing CDSS were categorized into 6 groups according to the participants. These include barriers from human resources and infrastructures as well as financial, technical, environmental and legal ones. The barriers for them were divided into 5 categories including structural, technical, financial, human and environmental ones.Conclusion: Since the most significant obstacle in implementing CDSS in this hospital was from humans, the hospital can use the barriers provided in 5 categories and better benefit from the system. These barriers are training the human resources before they start working, engaging them in implementation process of the CDSS and using evidence-based scientific databases in CDSS while removing fundamental barriers to the system.
