Job stress and health status of employees are effective on efficiency and quality of their services. Mental health status of midwives is very important in offering health and medical services to two vulnerable groups including mothers and infants; therefore the evaluation of effective factors on this issue seems to be necessary. This study was performed to determine the relationship between mental health and job stress among midwives who were working in hospitals of Kerman، Iran. This cross-sectional study was conducted on 74 midwives who were working in public and private hospitals of Kerman، Iran، 2011. Sampling method was census. Goldberg mental health and Altmeyer job stress standard questionnaires were used to collect data. Data were analyzed using SPSS software version 16 and descriptive statistics، Pearson correlation coefficient، t-test and chi-square test. P value less than 0. 05 was considered significant. There was a statistical significant relationship between mental health and job stress among midwives (p<0. 05). 29 midwives (39. 2%) were mentally healthy. 45 midwives (60. 8%) had some degree of mental disorder and 30 midwives among them (66. 7%) were working in public hospitals and 15 midwives (33. 3%) were working in private hospitals. Also، 1 person (1. 3%) of midwives had mild stress، 60 midwives (81. 1%) had moderate stress and 13 midwives (17. 6%) suffered from severe stress. Job stress can cause mental disorders in midwives. Also، midwives who were working in public hospitals are more exposed to job stress than midwives were working in private hospitals.

The polycystic ovary syndrome (PCOS) is a complex endocrine disorder characterized by reproductive and metabolic disturbance. It is the most common cause of infertility. The aim of this study was investigating the effect of aerobic training on obesity status، insulin resistance and serum levels of anti-mullerian hormone in PCOS patients. This quasi-experimental study was conducted on 22 PCOS women who referred to Kosar clinic in Arak، Iran in 2012. Patients were randomly divided into aerobic training and control groups. The exercise protocol consisted of aerobic training 3 days per week for 8 weeks. At weeks 0 and 8،fasting blood samples and anthropometric measurements were collected. Data were analyzed using SPSS software version 15 and Kolmogorov-Smirnov and dependent t-test. P value less than 0. 05 was considered significant. Body weight (p<0. 002)، body mass index (p<0. 05)، waist circumference (p<0. 001)، total cholesterol and triglyceride levels (p<0. 02) were significantly decreased in training group، whereas VO2 peak increased by exercise (p<0. 05). Changes in serum anti-mullerian levels and insulin resistance index were not significant in either of the groups (p>0. 05). Aerobic training improves metabolic and morphological status in PCOS patients. This beneficial effect is not associated with alteration in serum anti-mullerian hormone levels.

Today، the use of cellular phones has become an inevitable part of people’s life. Some previous studies have shown the harmful effects of radiation of cellular phone on human health. The aim of this study was to determine the effects of electromagnetic radiation of cellular phone on parameters of human semen analysis. This prospective clinical trial was carried out on 50 semen samples of men who referred to Noor laboratory of Ahvaz، Iran in 2013. Before semen analysis، each semen sample was divided into two equal volumes (case and control). A current cellular phone in active mood was placed at a distance of 2. 5 cm from semen samples of case group for 60 minutes. No intervention was performed for samples of control group. After 60 minutes، semen analysis was done for all samples. Sperm count، concentration of motile and functional sperms and sperm morphology were compared in both groups. Data were analyzed using SPSS software version 16، Kolmogorov-Smirnov and t-test. P value less than 0. 05 was considered significant. The differences of sperm morphology (p=0. 11) and total sperm count (p=0. 12) were not significant in both groups. Motile and functional sperms concentration in case group were lower than control group (p=0. 001). It seems that cellular phones have negative effects on human semen analysis and reduces total sperm count and functional sperms.
