Gestational diabetes mellitus (GDM) is a serious pregnancy complication in which a woman who has never had diabetes develops chronic hyperglycemia during her pregnancy. Normal placental function is essential for optimal fetal growth. The transport of glucose from the mother to the fetus is critical for fetal nutrient demands and can be stored as glycogen in the placenta. However, the function of this glycogen deposition is unknown: It may well be a source of fuel for a placenta itself or the storage reservoir for the later use by the fetus in times of need. While the significance of the placental glycogen remains unknown, the mounting evidence indicates that the altered glycogen metabolism and/or deposition is associated with many pregnancy complications, such as gestational diabetes, that adversely affect fetal development. The aim of this study is to assess glycogen deposition using Histochemical staining of Periodic Acid Schiff (PAS) stain. The placenta tissue collected from 50 women were enrolled in this study (25 women with no complications) and (25 women with gestational diabetes). The placentas of the two groups were compared in this study based on glycogen deposition with periodic acid-Schiff stain. The results of a histochemical investigation using PAS stain revealed a significant increase in the glycogen deposition (p≤0.001) in diabetic women's placentas within the intervillous core, around fetal vessels, and the basement membranes.
It was observed that embryos from oocytes resulting from well-vascularized follicles had a higher implantation rate than those from oocytes developed in poorly vascularized follicles. Neovascularization was recognized as primary in terms of ovulatory follicles growth and selection. Vascular endothelial growth factor serum level has a positive correlation with perifollicular blood flow. The 2D Color and Pulsed Doppler ultrasounds that allow visual observation of the flux of the blood in a limited part of the wall of the preovulatory follicles can be easily measured. To study the preovulatory follicle's blood flow parameters in infertile women undergoing different ovulation induction protocols. 50 infertile female patients who had undergone Intrauterine Insemination (IUI) procedures were classified into two groups which were letrozole or clomiphene citrate groups as induction protocol. Another ultrasound was performed on cycle day 11, 12, or 13 to evaluate growth follicles, also a Doppler study was done to measure perifollicular blood flow and endometrial thickness at the same time blood sample to measure vascular endothelial growth factor were taken. Human chorionic gonadotropin was injected and then after 36-40 hrs. IUI Procedure is done and follows up with the patient to do a pregnancy test after 14 days. The number of dominant follicles, endometrial thickness at HCG trigger, Perifollicular doppler blood flow vascular endothelial growth factor level, pregnancy rates were all measured in both groups. There were significant differences in Perifollicular RI (p<0.001) but there were no significant differences in Perifollicular PI (p=0.476). Regarding pregnancy rate, the letrozole group has a higher although not significant pregnancy rate (32%), if compared with those using CC (20%).
Node-like receptor pyrin 3 is a tripartite protein composed of an amino-terminal pyrin domin (PYD), nucleotide binding NACHT domine, and a carboxy-terminal leucine-rich repeat (LRR) domine, and consider an intracellular sensor that detects a broad range signal and resulting in the formation and activation the NLRP3 inflammasome. This complex lead to the release of the inflammatory cytokines IL-1β, IL-18 which is important for host defense against invading pathogen. Modern evidence indicates that the NLRP3 inflammasome is involved in gestational hypertension. This study was conducted on fifty pregnant women and divided into two groups: 25 placentas from normotensive mothers having no hypertension before as the control group and 25 from gestational hypertension women as gestational hypertension group, obtained from the Department of Obstetrics and Gynecology in Almosil El Aam Hospital and Alkhanssa Teaching Hospital, Mosul city, Iraq. The placental tissue samples were collected from the central region and processed for an immunohistochemical technique to t h e expression of NLRP3 in placental tissue. The immunohistochemical study of t h e placenta of the gestational hypertension group showed the localization of NLRP3 protein and staining intensity in trophoblast, stroma, and endothelium villi were high quantification compared with placenta from the control group.
The effect of maternal body mass index (BMI) on fertility outcomes in women undergoing in vitro fertilization/intracytoplasmic sperm injection cycles has been extensively evaluated and the results of these studies have shown a lot of controversial issues. Folate is a naturally occurring type of vitamin B9 crucial for reproductive health. 65 infertile couples were subjected to intracytoplasmic sperm injection cycles. Both primary and secondary types of infertility were involved, with different causes. The mean plasma folate of all infertile women was 12.71±6.52, with pregnant 11.60±5.57 and non-pregnant 11.74±8.80; with no significant difference in mean plasma folate between them. Moreover, the means of follicular fluid folate of all infertile women, pregnant women, and non-pregnant women were 8.00±5.39, 7.84±4.68, and 8.39±6.19 respectively. There was no significant statistical difference in mean follicular fluid folate between pregnant and non-pregnant women (p=0.719). Also, both plasma folate and follicular fluid folate were not significantly correlated to oocyte and embryo characteristics. Although plasma folate was higher in obese than normal and overweight women, the difference did not reach statistical significance. It appears that the correlation among maternal BMI, folate level and fertility outcomes in women undergoing intracytoplasmic sperm injection cycles are still controversial and much research work is needed to figure out such complex interaction among these variables.
