Peritoneal dialysis is one of the most efficient treatment in ESRD. Peritoneal sclerosis and malnutrition are side effects of peritoneal dialysis. Cancer antigen 125(CA125) is made by peritoneal mesothelial cells and increases during peritoneal inflammation. Peritoneal biopsy s an invasive method using for diagnosis of peritoneal sclerosis but serum CA125 is a noninvasive method used for prediction of peritoneal dialysis recently. The aim of this study was to investigate the relationship between serum CA125 with peritoneal function and malnutrition parameters.
This cross- sectional study was carried out in Yazd 2014. A total of 50 peritoneal dialysis patients were selected by convenience sampling. A questionnaire consists of malnutrition and peritoneal functional parameters and demographic characteristics of patents was completed. SPSS version 20 and T test. Anova, chi -square and logistic regression tests used for data analysis.
In this study, there was a direct association between serum CA125 and serum triglyceride, LDL and invers more association between CA125 and serum albumin but there was no association between CA125 and peritoneal function parameters.

Noise is one of the most common physical harmful agent in the work places with different severity in almost all industries. The noise higher than the standard level can be a potential source for human injuries. The aim of this study was to evaluate noise induce hearing loss among welders.
This cross - sectional study was done in 2013 to 2014 on the welders who referred to occupational medicine centers of Shohadaye Fardis to do occupational medicine checkup. Audiometric test was done in acoustics room for both ear and after data collection, statistical analysis was performed using SPSS software (version 22).
The results showed that among 54 welders (5.17% of all referred persons), 18 persons (33.3%) has hearing problems, 36 persons (66.7%) of persons were healthy. among welders with hearing loss, 6 persons (33%) had unilateral NIHL and 11 persons (66%) had a bilateral NIHL. hearing loss was more in 6000 Hz frequency in the left ear.
Research showed that welders are prone to hearing loss and requires corrective and preventive actions in order to control their hearing system damage.

Pressure ulcers are serious health problems, common but preventable and defined as care quality indicator for health care provider services. Pressure ulcers had negative consequences for patients and healthcare systems. The aim of this study was to determine mortality and length of hospital stay in elderly people with hospital acquired pressure ulcers in Alborz Hospital of Karaj 2012.
132 records belong to elderly people with hospital acquired pressure ulcers of Alborz Hospital in Karaj 1391, through convenience sampling were studied retrospectively. Include criteria was age >65 years, minimum 2-day stay in hospital and hospital acquired pressure ulcers. Data were analysis by descriptive statistics, t-test, ANOVA and chi-square tests.
The findings indicated that 15.2% of elderly patients with hospital acquired pressure ulcers was died. Mortality significantly was associated with hospitalized in intensive wards (p Focus on strategies for the prevention of ulcers, particularly in older adults hospitalized in intensive wards, neurological problems and prevent progression of ulcers can help to reduce length of hospital stay and mortality in these patients.

Plastic surgery intended to beautify has emerged along with modernity. It becomes one of the social norms by majority acceptance and it is considered as one of the individual daily concerns, particularly among women. In this research, it is stressed on the necessity of studying the psychological reasons women; tend to cosmetic surgery.
This study is a survey and the data collection tool are standard Rosenberg self-esteem questionnaire (SES) and self-image questions based on Schilder theory that are filled by 400 people of women living in Shiraz in 1394. Then collected data was analyzed through SPSS16 software by logistic regression, chi-squared test and phi Cramer. The sampling was geographical cluster multistage. With the help of the urban block map, areas were randomly selected and questionnaires were given to the respondents at their homes.
It is found that there is a meaningful relationship between the studied depended variable and income, age and education. A significant relationship between marital status and the rate of cosmetic surgery has been also confirmed.
The existing meaningful relationship between married status and the rate of trend toward cosmetic surgery is denied. The significant relationship between employment and trend rates toward cosmetic surgery is rejected. By increasing the rate of self-esteem and satisfaction of physical image, trend to cosmetic surgery decreases
Modernity has provided a different conditions from before for everyone. It has given the power of choice and power of change to people including changes in body. In this research, which aims to study psychological factors affecting women tendency to cosmetic surgery, the findings are consistent with theoretical social psychology written in this study. But with the recent changes, some thinkers Considered, being a woman is high-risk in this period and they believe that the female body which is approved by others will be defined in a risky culture.

Backgrounds and Mycoplasmas are distinguished phenotypically from other bacteria by their minute size and total lack of a cell wall and are involved in urogenital infections in both male and females. The aim of this study was to evaluate the presence of Mycoplasma genus and Mycoplasma homonis and genitalium in urine samples of athletes and non-athletes.
In this study, urine samples were taken from 50 athlete and non-athlete males and were transported to laboratory. After DNA extraction, PCR was performed using specific primers to identify Mycoplasma genus and species hominis and genitalium.
Among 100 samples, 5 were positive for Mycoplasma genus which all the 5 isolate belonged to non-athlete persons. In 5 positive samples, 3 belonged to Mycoplasma hominis and 2 belonged to Mycoplasma genitalium.
This study showed the presence of Mycoplasma in athletes were less than non-athletes. In addition PCR was a sensitive and precise method to identify Mycoplasma genus and species.

Electrospinning of chitosan/poly ethylene oxide (CS/PEO) and poly caprolactone (PCL)/ CS/ PEO/ solutions with the addition of vancomycin to create nanofibers with antibacterial properties were examined.
Polymeric nanofibers including CS/PEO and PCL /CS/PEO/ vancomycin were produced by electrospinning method. The morphology of electrospun nanofibers was studied with use of scanning electron microscopy (SEM). Moreover, the chemical structures of the nanofibers were evaluated by FT-IR. The drug release of nanofibers was also investigated by UV-Vis spectrophotometry. The antibacterial activity of scaffolds was tested by two type bacteria including Streptococcus pyogenes and Staphylococcus aureus.
The SEM images indicated that the addition of vancomycin as much as 0/8%wt brings about the best nanofiber. Also, the morphology of electrospun nanofiber is dependent on the viscosity of the solution and the ratio of PCL/CS /PEO/vancomycin. According to the results of vancomycin releasing from nanofibers, the best results were obtained in the presence of PCL/ CS/PEO/0/8%wt vancomycin nanofibers as healing sample.
The result of antibacterial activity of nanofiber and drug releasing showed this nanofiber can used as an antibacterial coating to prevent the spread of infections in the wound surface.

Maprotiline hydrochloride is a norepinephrine reuptake inhibitor; that is using for the treatment of depression. In this research, were studied the effect of maprotiline on changes of the testicular tissue and the concentration of testosterone and gonadotropins in newborn male rats from the mothers treated with this drug.
In this experimental study, 40 newborn male rats wistar strain, from pregnant mothers that received 30, 60 and 90 mg/Kg of maprotiline hydrochloride in the three experimental groups orally for pregnancy period that is 21 days. Divided to 5 group of 8 animals. The control group received nothing, and the sham group received solvent. In 22th days after parturition, the newborns weighted and blood samples were taken from the hearts, and concentrations of FSH, LH and testosterone were measured by RIA method. The newborns testes were separated and histological changes were studied.
60 and 90 mg/kg of maprotiline hydrochloride can be reduced significantly testosterone levels while it increased significantly LH levels compare with control group (p 60 and 90 mg/kg of maprotiline hydrochloride decreases significantly the concentration of testosterone and the number of spermatogenic cells and increases LH levels.

The status and role of each country in scientific outputs in specific fields may indicate the potential and its performance in promoting and improving that particular issue. This study aimed to investigate Iranian scientific production in the field of Occupational and Professional Health and determine its level in Region and the World.
This is Survey-Descriptive study with Scientometrics approach. Population study includes 1787 scientific articles and papers in the field of Occupational and Professional health which published and indexed in Scopus database during 2000-2016. We use SPSS, NodeXL and VOSviewer to analysis data and design graphs.
Findings: Finding shows that Iranian scientific outputs in the field of Occupational and Professional Health increase from 3 in 2000 to 266 in 2016 and have 34% growth every year. Also we fended that Tehran University of Medical Science and United States as the most important center and co-worker in publishing scientific production.
Conclusion Although Iranian scientific production in the recent years have an acceptable increasing, but totally Iranian place of scientific production in the field of Occupational and Professional Health were not suitable in the world. Also the quality of published articles was in medium level. Making policy and Tacking good decision related to growth of quality and quantity of scientific papers by increasing level of scientific collaboration and use all internal potential seems necessary.
