Knowledge and critical thinking skills are necessary for improving clinical performance and delivering an acceptable midwifery care and critical thinking skills is an educational standard in midwifery education. The aim of this study was comparing the critical thinking skills between first-year and final-year undergraduate midwifery students in Mashhad Nursing and Midwifery School. This descriptive-comparative and cross sectional study was conducted on 44 first-year and 22 final-year undergraduate midwifery students in Mashhad Nursing and Midwifery School in 2010-2011. Data were collected using a demographic form and California Critical Thinking Skills questionnaire and analyzed using SPSS software version 14، t-test، Mann-Whitney، ANOVA، Friedman، Pearson and Spearman correlation coefficient tests. P value less than 0. 05 was considered significant. The mean score of critical thinking skills for first-year and final-year undergraduate midwifery students were 10. 8±2. 5 and 10. 8 ±3. 4، respectively and in the normal range. There was no significant difference between two groups regarding critical thinking skills and its different dimension (p>0. 05). There is no significant difference between critical thinking skills in first-year and final-year undergraduate midwifery students.

Evaluation the factors associated with premenstrual syndrome creates a general approach to management of stress. The aim of this study was determining the relationship between stress and symptoms of premenstrual syndrome in students of Mashhad University of Medical Sciences. This cross sectional study was conducted on 115 student of Mashhad University of Medical Sciences in 2013. Sampling was randomly. Data were collected by Health-Promoting Lifestyle Profile II (HPLP2) questionnaire، a questionnaire of provisional diagnosis of premenstrual syndrome، and daily record form of symptoms of premenstrual syndrome. Data were analyzed using SPSS software version 16 and Spearman correlation coefficient، Mann-Whitney، t-test and Kruskal-Wallis tests. P value less than 0. 05 was considered significant. 65 students were suffering from premenstrual syndrome and severity of symptoms was mild in 24 cases (36. 9%)، moderate in 24 cases (36. 9%)، severe in 10 cases (15. 4%) and very sever in 7 students (10. 8%). The mean score of stress was significantly lower in student with non-premenstrual syndrome symptoms (p<0. 001). There was a direct significant correlation between stress scores and intensity of premenstrual syndrome symptoms in student with premenstrual syndrome symptoms (p<0/001). Students with less stress have lower premenstrual syndrome symptoms.

Recurrent miscarriage is a reproduction problem، experienced by 5% of couples. Considering the relationship between thrombophilia and abortion، the aim of this study was evaluating the relationship between factor XIII gene polymorphism G103T as a factor in the coagulation pathway and recurrent miscarriage. This case control study was done during 2010-2011. Patients were divided into two groups; 105 women with 2 or more miscarriage as case group and 98 healthy women with two or more children and no history of abortion، as controls. DNA was extracted from their leukocytes using salting out method. The status of the G103T variant was determined by PCR-RFLP. Amplifying the corresponding region of genomic DNA followed by treatment with restriction enzyme Dde1. Data were analyzed using SPSS software version 18 and chi-square test. P value less than 0. 05 was considered significant. 84 women (80%) in case group and 31 women (32%) in control group have 103GT/103TT genotypes and the difference was statistically significant (p<0. 001). The allelic frequency for G103T variant also showed significant difference between two groups (p<0. 001). G103T polymorphism can cause miscarriage via coagulation system dysfunction
