Abstract
Introduction: Preeclampsia is one of the three major causes of death in pregnant women. Researcher believed that consuming proper nutrients can be a solution. In the last few years, the effect of type of fruits and vegetables on prevention of preeclampsia has been investigated, but there are still questions about the proper amount (unit) of fruits and vegetables. Materials and Methods: This case-control study was done on pregnant women referring to Thaleghani hospital in Arak. 35 pregnant women with preeclampsia were selected as case, and 70 healthy pregnant women as control group. The two groups were matched. Data were collected with a questionnaire consisting of two parts, first demographic information and second information about the amount of consumed fruits and vegetables. Each woman was questioned about food consumption 3 month before and during second trimester of her pregnancy. Portion of fruits and vegetables was calculated per week and then compared between the two groups. K-S, Leven, Mann-Whitney, and Chi2 tests were used for analyzing data. Results: In preeclampsia group, 3 month before pregnancy mean consumption of fruits and vegetables was 7.69±16 per week, and in healthy group was 12.43±1.87. There was a significant difference between the two groups (p=0/029). In the second trimester of pregnancy the mean was 11.03±1.6 and 13.95±0.98 in case and control group, respectively. Differences were significant (p=0.03). Incidence of preeclampsia was increased in group with less than 25% consumption of fruits and vegetables before pregnancy (less than 5unit per week) (P=0.05, OR:2.32, 95%CI:1/7, 7/24). This difference was also significant in the second trimester (P<0/03, OR:2.57, 95% CI:1/4, 54/29). Also in women who consume less than 8 units per week, the incidence of preeclampsia was increased. Conclusion: It was concluded that it seems there is relationship between consumption of fruits and vegetables with decreasing occurrence of preeclampsia. So researchers suggest that high risk groups of women be identified and educated to consume fruits and vegetables.

Abstract
Background: Hypertension disorders are the most common medical complication during pregnancy. Preeclampsia is an important cause of mortality. The pathophisiology of it is still unknown. But sex hormon especially testosterone may be has a role in preeclampsia. We were conducted the comparison of serum free testosterone level in preeclamptic with normotensive pregnant women. Methods and Materials: This research was a case-control study included 27 women with singleton pregnancy who were complicated with preeclampsia (11 with severe preeclampsia and 16 with mild preeclampsia) and 62 normotensive pregnant women who were matched for age, body mass index (BMI) and gravity. Serum levels of free testosterone were measured by ELISA method. Results:Serum testosterone level was higher in preeclamptic group (1.66 ng/ml) than in mean of the control group (1.27 ng/ml), but this difference was not significant. Mean of testosterone levels in sever preeclampsia were higher than mild preeclampsia patients, however it was not statistically significant (2.08, 1.37, respectively). Conclusion: It seems that testosterone has not significant role in the pathogenesis of preeclampsia. .

Abstract
Background: Preeclampsia is one of major reasons of mortality in mother and child and its early diagnosis is one of the most important parts of health care during pregnancy. The current study was done to find the relationship between hemoglobin and hematocrit in the first trimester of pregnancy and the incidence of preeclampsia in women referring to Milad Hospital in Tehran in 2009-2010.
Materials and Methods: This prospective cohort study was conducted on 700 pregnant women in the first trimester of pregnancy, selected by convenience sampling. Prenatal tests were run in Milad Hospital and the results were recorded. Then samples were monitored for preeclampsia until delivery. Data were analyzed by SPSS version 18 (P < 0.05).
Results: The highest percentage of research groups suffering from preeclampsia was in hemoglobin ≥12/5% g/dl and hematocrit of ≥38% group. There was a significant relationship between hemoglobin and hematocrit levels during the first trimester of pregnancy and preeclampsia (P<0.001, P=0.002). Hemoglobin of ≥ 12.45 g/dl presented a sensitivity of 85%, the specificity of 43.04%, positive predictive value of 9.63%, and negative predictive value of 97.57%. Hematocrit of ≥ 38% presented the sensitivity of 77.5%, the specificity of 50.71, the positive predictive value of 10.1%, and the negative predictive value of 96.93%.
Conclusion: The presence of high hemoglobin and hematocrit in the first trimester of pregnancy can be a predictive factor for diagnosing preeclampsia

Abstract
Background and Aim Preeclampsia is a common complication of the second half of pregnancy. Sleep disorders can cause high blood pressure by causing oxidative stress and endothelial dysfunction. Therefore, the present study was performed to determine the relationship between sleep disorders and preeclampsia.
Methods & Materials This is a case-control study that was performed on 240 women referred to the affiliated university hospitals in Mashhad. Sampling was performed in the case group of hospitalized women with a definite diagnosis of preeclampsia (n=90) and in the control group (n=150) among pregnant women without preeclampsia referred to the obstetrics clinic. Data collection tools included demographic information questionnaire and gynecological/obstetric records, Pittsburgh Sleep Quality Questionnaire and clinical evaluation form to determine the symptoms and severity of preeclampsia. Data analysis was performed using SPSS statistical software (version 22) and Mann-Whitney, Chi-square and Fisher tests. A P value of less than 0.05 was considered significant.
Ethical Considerations The present paper is the result of a research project approved by the Vice-Chancellor for Research of Mashhad University of Medical Sciences (Code: IR.MUMS.NURSE.REC.1397.042).
Results The mean amount of real sleep at night in the group of healthy individuals (8.4±2.3) was significantly higher than patients (8.0±2.2) (P=0.028). In terms of loud snoring, waking up in the middle of the night was most frequent in the affected group (P<0.001). There was a statistically significant difference between the two groups in terms of sleep quality score level (P<0.001) based on logistic regression test in women with severe sleep problems at risk of preeclampsia (P<0.001, 95% CI 2.9-42.2, OR: 11/11) (11/11) was equal compared to healthy women.
Conclusion The present study showed that sleep disorders in pregnancy are associated with an increased risk of preeclampsia.
