Abstract
Background: Noticing the fact that graft survival rate of kidney transplantation from live donors is more than deceased donors, this study was conducted to determine the relationship between the graft survival rate of renal transplantation and the donor source in patients transplanted from March 1999 to March 2009 in Namazi Hospital Transplantation Center of Shiraz. Materials and Methods: In this retrospective cohort study which was designed to determine the relationship between graft survival of kidney transplantation and the donor source (related live donor, unrelated live donor, and deceased donor) in 1356 patients who were transplanted in Shiraz Transplant Center, Namazi Hospital. Kaplan-Meier method was used to determine the survival rate, log-rank test was used to compare survival curves and Cox regression model was used for ruling out the intervening factors. Results: Five-year graft survival rates of renal transplantation from related, unrelated, and deceased donors were 92.4, 92.6 and 82.1%, respectively. Also, a significant relationship was seen between donor source and survival rate of the renal allograft (P>0.001). Conclusion: The findings of this study transplanted patients with kidneys from living donors (related or unrelated) have a higher graft survival rate compared with deceased donors.

Abstract
Human Brucellosis is an infectious disease caused by Brucella bacteria. An average of 150 cases of brucellosis among 330 million people is reported in the USA each year. This bacterium is small, gram-negative rods that grow in phagocytes. They primarily cause diseases among different animals and humans become infected when is in contact with animals or their products. Brucella can cause various symptoms in humans which is similar to human influenza. Brucellosis is diagnosed in a laboratory by finding Brucella organisms in samples of blood or bone marrow or to detect antibodies against the bacteria in two blood samples, collected 2 weeks apart. Depending on severity of illness, recovery may take as long as several months. There is no vaccine available for human except live vaccines and that should be consulted to a health care provider. DNA findings for Brucella species in the index patients focused our attention on revealed human cancers. Also, granalomatous inflammation of testes and medulloblastomas has been linked to chronic Brucellosis infection which could be similar to Helicobacter pylori that is associated with gastric tumor formation. More scientific investigation is needed to properly address the connection of Brucella with other human malignancies.

Abstract
Background: Prevention, control, or eradication of brucellosis in a country or region needs policy-making, decision-making, and possessing accurate epidemiological data and information. Therefore, this study was done to review the epidemiology and some factors affecting the interval between the onset and diagnosis of brucellosis in Markazi Province, Iran.
Materials and Methods: In this cross-sectional study, data on patients diagnosed with brucellosis during 2010-2011 in Markazi Province were studied. Data were analyzed by descriptive statistics as well as chi-square test, Fisher's exact test, t-test, and Kolmogorov-Smirnov test using SPSS software.
Results: Out of all cases (907), the interval between the onset of symptoms and diagnosis was more than a month in 363 cases (41.7%). The interval between the onset and diagnosis was significantly associated with location (urban or rural) (P=0.001), city of residence (P=0.001), career (P=0.002), and type of disease (new or failure case) (P=0.008).
Conclusion: Since the interval time between the onset and diagnosis of brucellosis among rural residents, ranchers, housewives, and farmers is more, greater attention should be paid to this new class.

Abstract
Background: Leukemia is the most common type of cancer in children which its relapse decreases the patients’ survival rate. The aim of this study was to determine the risk factors involved in leukemia relapse in patients in Shahid Faghihi Hospital, Shiraz, during 2004-2009 years.
Materials and Methods: In this retrospective cohort study, 280 patients with acute lymphoblastic leukemia and acute myeloid leukemia were included. Patient characteristics were analyzed with respect to their association with recurrence through Chi-square test, Fisher’s exact test, and logistic regression model using SPSS software version 16 (P-value<0.05).
Results: Logistic regression model revealed a statistically significance relationship between age and recurrence of the disease (odds ratio (OR) = 0.35, 95% confidence interval (CI) = 0.15-0.82), odds ratio of relapse in the 5-10 years old age group was 0.35 times more than the 0-5 years old age group (p=0.01).
Conclusion: Noticing the greater likelihood of relapse in 0-5 years old age group compared with the 5-10 years old age group, more attention and better follow-up for decreasing the side effects of the disease and enhancing the survival rate of the 0-5 y/o age group are recommended.

Abstract
Background: Cataract is the leading cause of blindness and visual impairment. This study was performed to compare effects of two different incision types in cataract surgery on dry eye symptoms and diagnostic test values. Materials and Methods: In this clinical trial, 300 patients with cataract requiring phacoemulsification were studied. The patients were randomly divided into two operative method groups: limbal and clear corneal (anterior to the vascular arcade) incision. A complete set of ophthalmic examinations and tear related tests were done for all of the patients before surgery and one week and one month after surgery. The collected data were analyzed using SPSS and EPI-Info softwares. Results: Overall, 149 men and 151 women were enrolled in this study. On the first postoperative week, the means of symptoms, and TBUT and TMH values in both groups significantly decreased compared with the preoperative values. These values returned to the preoperative levels one month postoperatively which werein contrast to the changes of debri, PEE, corneal and conjnnctival staining. There were statistically significant differences between the results of pre- and post-operative symptoms, PEE, debri, TBUT, conjunctival and corneal staining. Except for TBUT, the results of these tests were not statistically different according to incision location. Conclusion: Phacoemulsification cataract surgery affects dry eye symptoms and diagnostic test values. In addition, except for TBUT, the location of incision had no effect on other test results and symptoms.

Abstract
Background: Prostate cancer is one of the most common cancers in men which its incidence rate and associated mortality and morbidity are on the rise. The aim of this study was to investigate the epidemiology of prostate cancer in Fars province between 2003 and 2008 years. Materials and Methods: In this epidemiological study, using Fars province cancer registry data, the incidence rates were calculated per 100,000 people and age standardized incidence rate (ASR) was measured by direct method using the world standard population. Data were analyzed by SPSS, version 16, and Microsoft Excel, version 2007. Cochrane Armitage Test for linear trend was used for evaluation of the incidence trend by running Winpepi software. Results: Over a 6-year period, 1212 cases were recorded in Fars province. The ASR of prostate cancer in these six years was 4.69, 7.16, 15.09, 14.04, 16.65 and 16.02, respectively, which revealed significantly increasing trends. The highest incidence rate was observed in 80 and upper age group. Conclusion: The ASR of prostate cancer in Fars province is significantly lower than other parts of the world, especially in more developed countries. This can be due to absence of screening programs and/or cancer registry.

Abstract
Background: Subclinical hypothyroidism is the compensatory stage before overt hypothyroidism. In overt hypothyroidism, risk of ischemic heart disease increases due to elevation of lipoprotein (a) as atherogenic agent, but evidence for subclinical hypothyroidism is one of the controversial issues in researches. According to the atherogenic lipoprotein (a) and other serum lipids, this study is conducted to compare the serum lipoprotein (a) and other serum lipids in patients with subclinical hypothyroidism and euthyroidism.
Materials and Methods: In this descriptive - analytic study, 90 persons (60 with subclinical hypothyroidism and 30 euthyroid state) are participated and these referred to Imam Reza and Taleghani Hospitals which are located in Kermanshah. The sampling method is selected with available sampling methods. After differentiating data by age, sex and underlying disease (liver, kidney, drugs), then they were subjected to determination lipoprotein (a) and other serum lipids profile tests.
Results: In both cases and controls, 16/7% were men and 83/3% were women. Based on results, there is no significant difference between serum lipoprotein (a), triglycerides, cholesterol, HDL and LDL in both statistical groups (p>0.05). Also there is no association between lipoprotein (a) and other serum lipids (p>0.05).
Conclusion: Serum levels of lipoprotein (a) and other serum lipids in young patients with normal weight with subclinical hypothyroidism is not increase, thus it can be concluded early treatment is not necessary for them.

Abstract
Background: Nutritional status assessment is a method for nutritional care which aims to determine nutritional needs and to meet nutritional requirements. Pregnant and lactating mothers are considered vulnerable groups. The use of this method, especially for determination of calorie and protein intake has positive effects on growth of neonates. Thus, the purpose of this study is to assess the nutritional status of pregnant women.
Materials and Methods: In this cross-sectional study, 80 pregnant mothers were selected from private and public hospitals in Arak. Data were gathered through a questionnaire including general information concerning pregnant mothers and their nutritional diet. The analysis of dietary intake was done by nutritionist IV software. Data were analyzed using SPSS software.
Results: The average weight gain for pregnant mothers at the end of pregnancy was 10.1kg. The mean of body mass index for the mothers was 22.2 kg/m2, and the average weight for neonates was 2.5 kg. The average energy intakes in mothers were equal compared with RDA, and the average protein intake was greater compared with RDA. There was a significant positive correlation between weight gain during and total body weight at the end of pregnancy (r=0.93) (p<0.01). Also, there was a significant negative correlation between weight of pre pregnancy and percent of weight gain at the end of pregnancy (r=-0.39) (p<0. 01). A significant positive correlation was found between total body weight at the end of pregnancy and birth weight of neonates (r=0.34) (p<0. 01).
Conclusion: Adequate nutritional status of mothers influenced normal body weight in neonates.

Abstract
Background: There is priority for evaluation of micronutrients (vitamin A) in the world, especially in develpoing countries like Iran. Vitamin A has an essentiall role in growth, reproduction, and maintenace of epithelial cells. Vitamin A, especially retinoic acid, acts like a hormone for gene expression. Vitamin A is necessary for growth of bones and immune system. The role of vitamin A in reducing mortality rates of neonates is well recognized. The aim of research is to evaluate this micronutrient (vitamin A) and the rate of transportation from mother to fetus and its positive effects on birth weight.
Materials and Methods: In this descriptive study, 90 pregnant mothers were selected from private and public hospitals in Arak. Data were gathered through a questionnaire including general information concerning pregnant mothers and also their nutritional diet. The analysis of dietary intake was done by Nutritionist IV software. The measurements of serum and cord blood retinol samples were carried with reverse phase HPLC. Data analysis was done by Pearson correlation.
Results: The results indicated a positive and significant correlation between cord blood retinol of mothers and birth weight of neonates (r=0.22) (p&ge0.05). There was not a significant correlation between serum retinol of the mothers and birth weight of the neonates. Also, there was no significant correlation between retinol intakes of the mothers and birth weight of the neonates.
Conclusion: Improvement of the retinol status of mothers has an effective role in normal birth weight of neonates.

Abstract
Background: The prevalence and incidence of cancer in different parts of the world have different patterns. To recognize the frequency of malignancies in different social groups according to climatic conditions is considered as the primary component of prevention programs at different levels. This study was conducted to investigate the epidemiology, survival rates and geographical epidemiology of breast cancer in Markazi province.
Materials and Methods: In this epidemiological study, needed data were obtained from cancer registration program and death registration data. The data were analyzed by using SPSS software version 16 and Winpepi and significant level was 0.05. And to draw a map to show the breast cancer incidence rate in Markazi district, Arc view software was used.
Results: Out of the 400 cases recorded during the 5-year, 8.5% died due to breast cancer. 5-year survival rate was 87% and there was a significant correlation between survival rate and age. Most records were related to the age group 49-40 years and the highest incidence rate was in Arak. The trends of incidence rate was not significant.
Conclusion: The results showed that 5-year breast cancer survival rate is more than some other places which could be due to new and improved methods of treatment and methods of screening and early detection of disease. Other aspects of the epidemiology of the disease is similar to other parts of Iran.

Abstract
Background: Toxoplasma gondii is an important pathogenic protozoan. This parasite can cause severe infection and may lead to abortion. Abnormal levels of cholesterol and other lipids in blood samples of infected persons have raised some questions on the role of these factors in the pathogenesis of Toxoplasma.This study aimed to measure and compare lipid and testosterone levels and the relationship between them among a selected group of men with and without Toxoplasma gondii IgG antibody.
Materials and Methods: This case – control study was conducted on a group of 20 to 29 years old men referred to the pre-marital clinics in Arak city in 2012. After completing a questionnaire, a blood sample (5 ml) was taken from each subject. Then, required diagnostic tests for toxoplasmosis was conducted. According to diagnostic results, 100 men with Toxoplasma antibodies were defined as cases and another group with equal number but without antibodies was defined as controls. Then, levels of testosterone and lipids in serum of these two groups were measured and compared.
Results: Findings showed that testosterone levels were in normal range in both cases and controls, but the hormone level was significantly lower among cases. There was no significant difference in terms of serum lipid levels.
Conclusion: Examination of relationship between blood testosterone and lipids levels among cases and controls showed that there was a significant negative correlation between testosterone and triglyceride levels. Also, there was a significant positive correlation between testosterone and HDL levels.

Abstract
Background: Hydatid disease is a parasitic infestation by a tapeworm of the genus Echinococcus. Man is an intermediate or accidental host of this parasite, and is infested by consuming contaminated plants or vegetables, or by contact with dogs. The larvae travel through the gut wall and 60-75% are filtered by the liver, and a few travel directly to the lungs to produce a hydatid cyst there. Growth of hydatid cysts has been reported in the spleen, muscles, bones, and brain. Hydatid cyst embolism to peripheral limb arteries is extremely rare.
Case: A 41-year-old gravided woman presented with sudden pain, erythema and warming of the olden infra-inguinal mass which existed from 1 year ago. The notable findings at physical examination included 40*20 mm diameter soft mass with warming and erythema in 4 cm below inguinal ligament of right lower limb. She didn’t mentioned any previous history hydatid cyst. Intraoperatively, Percutaneous aspiration of the mass was performed which demonstrate white turbid fluid. after the surgical incision we saw the white colored subcutaneous hydatid cyst and completely remove it and send it to pathological examination which confirmed hydatid cyst diagnosis. further liver ultrasound and chest radiography hasn’t shown any evidence of liver or lung involvement.
Conclusion: Cystic echinococcosis may affect all organs, but mostly settles in the liver and lungs. We do not have data on the means by which the larvae of echinococcosis reach the inguinal area without liver and lung involvement. Considering the anatomy of the groin and its lymphatic tissue, we can make an assumption about how the hydatid cysts settle in the groin space. Although it occurs rarely, larvae in the gastrointestinal tract may pass to the lymphatic circulation, and then settle in the groin space through the rich lymphatic flow of inguinal area.

Abstract
Background: Glaucoma is the second most common cause of blindness and it is one of the main causes of irreversible blindness. Multi-drug regimens usually recommended in reducing intraocular pressure (IOP) in patients with glaucoma. This study was aimed to compare the effect of combination therapy with Timolol and Latanoprost vs. Timolol and Dorzolamide in reducing IOP in patients with open-angle glaucoma.
Materials and Methods: In this blind randomized clinical trial study, 60 eyes with glaucoma were randomly assigned to two treatment groups including Timolol and Latanoprost vs. Timolol and Dorzolamide. Required variables were measured before and 6 weeks after the intervention. The data was analyzed by running the Stata software (version 12) at a significance level of 0.05.
Results: The mean age in groups of Timolol-Latanoprost and Timolol and Dorzolamide was 72.6 and 67.6 years old, respectively. Analysis of the data revealed that there was no significant difference between groups in terms of intraocular pressure (IOP), visual acuity and cup to disc ratio.
Conclusion: According to our findings, there were no statistical significant differences in the IOP lowering effect between both treatments in open angle glaucoma patients.

Abstract
Introduction: Today, with the increase in population, the per capita production of waste materials and the subsequent threat and destruction of the environment is an increasing process, and waste management by the people of a society can play an essential role in reducing this problem. Therefore, the aim of this study was determine of predicting the waste management behaviors of households in Arak city in 2022.
Methods: This is a cross-sectional and analytical study that was carried out on 600 mothers of households in Arak city, who were selected by multi-stage sampling. The data collection tool was a valid and reliable researcher-made questionnaire that included demographic characteristics, knowledge, attitude and behavior of households in the field of waste management. Data were analyzed using SPSS software and t-test, chi-square and regression tests. This study was approved by the research ethics committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1401.040).
Results: The average age of the studied was 39±11 years and the number of family members was 3.6. In terms of type of housing, most of them lived in apartments (44%) and a smaller number lived in complexes (14%). 65 percent of the people had not received the training on the waste separation plan from the source, and among the effective training methods, the majority (38 percent) of the people had overestimated the effectiveness of the training through the Internet. The mean and standard deviation of knowledge was 66±19, attitude was 84±11 and performance was 73±18. The majority of the people studied had a good level of awareness and attitude. The regression analysis model showed that the greatest impact on the waste management behavior of the samples was the age of the people, their knowledge and attitude, which predicted a total of 33% of the waste management behavior.
Conclusions: Considering the favorable state of awareness and attitude of households in Arak city, it seems that for better waste management, other environmental factors should be emphasized, including sources of waste production at the source. Also, based on the prediction model, it is still important to inform and change the attitude of households in Arak city for better performance at younger ages.
