Placentas were divided into three equal groups: normal pregnancy (control group), nondiabetic macrosomia group, and macrosomia complicated with GDM (diabetic macrosomia) group. Gross morphological data of placentas were recorded, and placental samples were processed for examination of ultrastructural and stereological changes using transmission electron microscopy. Analysis of variance and chi-squared test were used to examine the differences among the three groups for continuous and categorical variables, respectively.\u0000 \u0000 \u0000 \u0000 The baseline characteristics of mothers and neonates did not differ across the three groups, except for a significantly higher birth weight in the diabetic macrosomia group (4172.00 ± 151.20 vs. 3192.00 ± 328.70, P < 0.001) and nondiabetic macrosomia group (4138.00 ± 115.20 vs. 3192.00 ± 328.70, P < 0.001) compared with control group. Examination of the placentas revealed that placental weight was also highest in the diabetic macrosomia group compared with control group (810.00 ± 15.81 vs. 490.00 ± 51.48, P < 0.001) and nondiabetic macrosomia group (810.00 ± 15.81 vs. 684.00 ± 62.69, P < 0.001), but the ratio of neonatal birth weight to placental weight (BW/PW) was significantly lower in the diabetic macrosomia group compared with that in the control group (5.15 ± 0.19 vs. 6.54 ± 0.63, P < 0.001) and nondiabetic macrosomia group (5.15 ± 0.19 vs. 6.09 ± 0.52, P < 0.001) group. In contrast, the BW/PW ratio in nondiabetic macrosomia did not differ significantly from that in the control group. Distinct ultrastructural changes in terminal villi and stereological alterations in microvilli were observed in the diabetic macrosomia group, including changes in the appearance of cytoplasmic organelles and the fetal capillary endothelium and thickness of the vasculo-syncytial membrane and basal membrane.\u0000 \u0000 \u0000 \u0000 Significant ultrastructural and stereological alterations were discovered in the placentas from pregnant women with macrosomia induced by GDM.

A recent study provides evidence that hampered wound healing results in cesarean scar defects that lead to a failure in the normal process of decidualization and deeper adherence of trophoblasts. Matrix metalloproteinase (MMP) is crucial in every step of wound healing as it alters the wound matrix, facilitating cell migration, as well as tissue remodeling. MMP-9 expression is higher in placental and decidual tissue in cases of placenta accreta. Based on these findings, assessment of MMP-9 expression can shed new light on the etiopathology of placenta accreta spectrum disorder and can be a potential diagnostic marker.","PeriodicalId":53202,"journal":{"name":"Maternal-Fetal Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140745176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the recognition of retinal imaging in cardiometabolic health grows, there is increasing evidence supporting its application in women’s health, particularly during the reproductive age. This review aims to summarize the indications of retinal imaging in women’s health and intergenerational health, where suboptimal retinal imaging has been found to mirror pathological systemic changes, such as suboptimal hemodynamic circulation, inflammation, endothelial dysfunction, oxidative stress, and hypoxia in vivo. Findings from Singapore Growing Up in Singapore Towards Healthy Outcomes and Singapore Preconception Study of Long-Term Maternal and Child Outcomes cohorts have reported serial changes in retinal conventional microvascular features (e.g., retinal arteriolar narrowing, retinal venular widening) and retinal geometric microvascular features (e.g., sparse fractal dimension, enlarged branching angle, and increased curvature tortuosity) during the preconception and antenatal phases. These morphological abnormalities were found to be related to female fertility, maternal antenatal health conditions, postnatal maternal cardiometabolic health, and intergenerational health in the fetus. Given the compelling evidence of the ability to detect microvascular changes through noninvasive methods at an early stage, retinal imaging holds the potential to facilitate timely interventions, mitigate the progression of complications, and prevent adverse pregnancy outcomes. Looking ahead, the convergence of artificial intelligence and advanced imaging techniques heralds a promising era in women’s health research and clinical practice.","PeriodicalId":53202,"journal":{"name":"Maternal-Fetal Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140742263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
