OBJECTIVE: The aim of this study is to find out the effect of delivery mode on newborn’s cord blood parameters particularly hemoglobin and hematocrite values. SETTING: Obstetrics and Gynecology Department, Qena Faculty of Medicine, South Valley University, Egypt. DURATION: From April 2015 to December 2017. STUDY DESIGN: A cross sectional study. METHODS: 900 live born neonates for healthy mothers were included in this study;all cases were delivered at full-term, with birth weight ranged from 2.5 to 3.5 Kg and had APGAR scores above 7 at 1 and 5 minutes. Newborns were divided into three groups (Group I included 300 newborns delivered by vaginal delivery without augmentation of labor, Group II included 300 newborns delivered vaginally with augmentation of labor and Group III included 300 newborns delivered by elective cesarean section). Blood sample was collected from the umbilical vein of each neonate for estimation of hemoglobin, hematocrit, RBCs count, platelets, WBCs count and reticulocytes. RESULTS: Cesarean section delivery had a statistically significant decrease in the level of iron-related hematologic indices including hemoglobin, hematocrit and RBCs count (p value elation among newborns cord blood hemoglobin as regard to head circumference, length and gestational age and negative correlations as regard to maternal age, parity and birth weight with no statistically significance (P value > 0.05). CONCLUSIONS: Cesarean section delivery had a significant decrease in the level of iron-related hematologic indices including hemoglobin, hematocrit and RBCs count and has a non-significant decrease in WBCs and platelets counts in neonatal cord blood, which suggest high prevalence of newborn iron-deficiency anemia among cesarean births particularly in developing communities.

Open Journal of Obstetrics and Gynecology 2019年第3期9卷 353-362页

作者： abd el-naser abd el-gaber ali Mustafa M. Khodry ART Unit of Obstetrics & Gynecology Department Qena Faculty of Medicine South Valley University Qena Egypt

Background: As regard to adjuvant supplementations, nowadays dehydroepiandrosterone (DHEA) is widely used all over the world and is considered to be a potential agent to ameliorate the assisted reproduction technologies outcomes of infertile women with poor ovarian reserve. Objective: To find out the role of DHEA supplementation in improving intracytoplasmic sperm injection (ICSI) outcome for infertile women with expected poor ovarian response in controlled ovarian stimulation. Setting: Assisted reproduction unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt. Duration: From April 2016 to May 2018. Study Design: A randomized double-blinded controlled trial. Methods: One hundred and forty infertile women with expected poor ovarian response prepared for ICSI procedure were included in this study. Patients were divided into two groups;group I (DHEA group) included 70 patients received 25 mg DHEA 12 weeks prior to ICSI cycle and group II (placebo group) included 70 patients received a placebo. Results: There was a highly statistically significant difference in basal AFC at start of ICSI cycle in group I (who received DHEA supplementation for 12 weeks prior to ICSI procedure) than in group II (13.8 ± 5.3 versus 10.7 ± 4.6 respectively) with P ality of retrieved oocytes, increased in endometrial thickness, fertilization rate and embryo quality with p value 0.05). Conclusions & Recommendations: DHEA supplementations improved basal AFC, increased the number & quality of oocytes and increased quality of embryos in infertile patients with expected poor ovarian response in ICSI procedure. So DHEA supplementations could be an important adjuvant for inferti

BACKGROUND: Sub-endometrial junction zone (JZ) plays an important role in most of reproductive functions. OBJECTIVE: To find out the effect of the sub-endometrial JZ thickness assessment by 3-D trans-vaginal ultrasound (TVUS) on intracytoplasmic sperm injection (ICSI) outcomes in patients with unexplained recurrent implantation failure (RIF). SETTING: ART Unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Qena, Egypt. DURATION: From April 2016 to October 2018. STUDY DESIGN: A prospective observational study. METHDS: Fifty couples with history of unexplained RIF in previous ICSI cycles and prepared for another ICSI cycle (group I) and fifty couples with unexplained infertility prepared for ICSI for the first time (group II) had been included in this study. At time of ovum pick up, 3-DTVUS was done for all cases in both groups for assessment of sub endometrial junction zone thickness and correlated with ICSI outcome. RESULTS: There were statistically significant differences between group I and group II in JZ thickness in the 3 uterine regions (fundus, anterior and posterior walls) with p 0.001, but there were mildly statistically significant differences between both groups in chemical and clinical pregnancy rates with p ely correlated with increased embryo implantation rates in ICSI procedures, the thinner the JZ thickness was associated with higher pregnancy rates (both chemical and clinical pregnancy rates).

OBJECTIVE: To assess the effect of vitamin D supplementation on enhancement of embryos implantation rates in intracytoplasmic sperm injection procedures. STUDY DESIGN: A randomized double-blinded controlled trial. SETTING: Assisted Reproduction Unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt. DURATION: From December 1st 2017 to the end of October 2018. SUBJECTS and METHDS: Eighty infertile couples that underwent ICSI procedure were entrapped in this study. Patients were divided into two groups;Group I (Vitamin D group) = 40 patients (received vitamin D supplementation in the form of Vidrop oral drops 600 IU/day starting after ovum pickup) and Group II (placebo group) = 40 patients (received a placebo “normal saline oral drop”). RESULTS: There was a significantly increased embryo implantation rates (53.2% in vitamin D group versus 46.7% in placebo group), there was a mild statistically significant difference in the clinical pregnancy rates (45.9% in vitamin D group versus 39.4% in placebo group) with p-value < 0.05 and there was an improvement in ongoing pregnancy rate as there was a mild statistically significant difference in first trimester miscarriage rates (12.5% in vitamin D group versus 17.5% in placebo group) with p value CONCLUSIONS: Vitamin D supplementation could improve embryos implantation rates and rate of ongoing pregnancy by decline in the first trimester miscarriage rate.
