Background & Objective: Conflicting results have been reported about the association between vitamin D and preeclampsia. The aim of the current study is to compare the serum levels of vitamin D in preeclamptic, and non-preeclamptic pregnant women admitted to the Ayatollah Mousavi Hospital in Zanjan. Materials & Methods:In this case-control study, 120 pregnant women were selected using convenience sampling in Zanjan in 2018-2019. Then they were divided into two groups, preeclampsia and non-preeclampsia. Both groups were matched one by one. The data were collected using a demographic information questionnaire and a researcher-made checklist. After obtaining consent from participants, blood samples were collected using the peripheral venous catheter. Then the ELISA test was used to measure vitamin D in participants. Data were analyzed by SPSS version 16 using, independent t-test, and Chi-square test (P≤0.05).Results: Of the participants, 64 (53.4 %) were between 20-35 years old, 48 (40%) were older than 35 years, and 8 (6%) were younger than 20 years. Most of the participants' gestational age was between 34 and 39 weeks (89.1%). The Mean (SD) of serum level of vitamin D was significantly higher in healthy pregnant women (19.06 (7.48)) than women with preeclampsia (16.60 (5.87)) (P<0.01). Among those with preeclampsia, the highest vitamin D level (17.17) was observed at 37-39 weeks of gestation. The lowest level (10.8) was for those with less than 34 weeks gestational age. Conclusion:This study demonstrated that vitamin D could be a protective factor for preeclampsia in pregnant women. However, further studies are recommended.

Background There has been several discussion and debates regarding the possible setremental influence of elevated serum progesterone (SP) on the day of human chorionic gonadotropin (hCG) administration. Our study aims to assess progestron to oocyte rates for assessing CPR and live birth rate (LBR) in IVF cycles and review previous articles. Methods In this prospective cohort study, women under ovulation induction through IVF-ICSI using the GnRH-antagonist protocol were studied. Five specific indicators were considered to assess pregnancy outcome. The statistical analysis was done using SPSS software. Results In the present research, 78 patients underwent IVF. The cut-off points for each of the three parameters were 1.2 (with a sensitivity of 65.4% and a specificity of 54%), 6.5 (with a sensitivity of 73.1% and a specificity of 56%), and 0.16 (with a sensitivity of 65.4% and a specificity of 60%, respectively). Only the number of oocytes (area below the curve of 0.64) was able to predict clinical pregnancy. The cut-off point for this parameter was 6.5 (with a sensitivity of 74.1% and a specificity of 66%). On the other hand, none of the parameters were able to predict live birth. Conclusions The findings of this study should assist in the clinical management of patients with high SP on the day of HCG administration. We recommend, that the ratio of SP to oocyte is a useful parameter for refining the criteria of patients who have had embryo freezing of all embryos (by selective freezing) and subsequent transfer of frozen embryos.

Background: Some recent trials have reported high efficacy for nonsteroidal anti-inflammatory drugs (NSAIDs) in relieving medical abortion-related pain. The aim of this study was to determine the beneficial effect of oral NSAIDs (ibuprofen lysine) in reduction of pain and hemorrhage in first-trimester medical abortion. Methods: This randomized triple-blinded clinical trial was performed on 98 pregnant women who were candidate for medical abortion within the first-trimester period (gestational age<12 weeks). The participants were randomly assigned to receive ibuprofen lysine (684 mg orally every 4 hours) or placebo. All patients were initially treated with misoprostol (800 µg every 3 hours). Pain intensity and rate of hemorrhage were assessed every hour up to 15 hours after receiving the first dose of misoprostol by visual analogue scaling (VAS) and pictorial blood loss assessment chart (PBAC), respectively. Results: Assessing the mean pain score within 15 hours of receiving misoprostol showed significantly lower pain intensity within the first 10 hours of assessment in the group receiving NSAID in comparison with the control group (P<0.001). The bleeding rate was also significantly lower in the NSAID group at the fifth (P=0.013) and ninth (P=0.040) hour of receiving misoprostol compared to the control group. We found no difference in abortion-related complication rate between the NSAID and placebo groups (8.3% versus 8.0%, P=0.952). Conclusion: The use of NSAIDs (ibuprofen lysine) is a good pharmacological analgesic option for relieving medical abortionrelated pain and hemorrhage.
