Evaluation of Pregnancy Risks in Women with Subchorionic Hematoma Using Machine Learning Models.

BACKGROUND Subchorionic hematoma (SCH) can lead to blood accumulation and potentially affect pregnancy outcomes. Despite being a relatively common finding in early pregnancy, the effects of SCH on pregnancy outcomes such as miscarriage, stillbirth, and preterm birth remain debated. This study aims to address these gaps by systematically evaluating the influence of SCH-related clinical factors on pregnancy outcomes using robust analytical techniques.

Peri-implantation treatment with TNF-α inhibitor for endometriosis and/or adenomyosis women undergoing frozen-thawed embryo transfer: A retrospective cohort study.

Problem: Endometriosis and adenomyosis have common pathogenesis and close relationship, with multi-factors involved in related infertility and IVF failure. They lead to anatomical changes, ovarian reserve reduction, endocrine abnormalities, altered endometrial receptivity and immunological dysfunction. Collective evidence indicate that abnormal function of immune cells and secretion of cytokines are closely related to reproductive outcomes among the women.

Methods: In this cross-sectional study, 428 female patients who visited the Department of Reproductive Center of Dalian Women and Children's Medical Group with chief complaints of infertility symptoms were recruited using convenience sampling from November 2022 to December 2023. Fertility-related stress and stigma status were examined by the Fertility Problem Inventory (FPI) and Infertility Stigma Scale (ISS), respectively.

Umbilical Cord-Derived Mesenchymal Stem Cells Improve Ornidazole-Induced Asthenozoospermia in Rats via Activation of the AKT/mTOR Pathway.

Mesenchymal stem cells (MSCs) have been highly confirmed for their critical role in the treatment of different diseases. This study focuses on the mechanism of umbilical cord-derived MSCs (UC-MSCs) in the treatment of ornidazole (ORN)-induced asthenozoospermia (AS) in rats via the AKT/mTOR pathway. An animal model of AS was established in ORN-induced rats, followed by treatment of UC-MSCs and rapamycin (autophagy activator) or MK-2206 (AKT inhibitor).

CTNND1 affects trophoblast proliferation and specification during human embryo implantation.

The placenta, serving as the crucial link between maternal and infant, plays a pivotal role in maintaining a healthy pregnancy. Placental dysplasia can lead to various complications, underscoring the importance of understanding trophoblast lineage development. During peri-implantation, the trophectoderm (TE) undergoes differentiation into cytotrophoblast (CTB), syncytiotrophoblast (STB), and extravillous trophoblast (EVT).

Surgical treatment of fallopian tubal pregnancy and interstitial pregnancy has no differential effect on intrauterine pregnancy after in vitro fertilization-embryo transfer.

Background: Due to the specific nature of interstitial pregnancy (IP), there are significant risks to both the mother and the foetus in women with a heterotopic interstitial pregnancy (HIP). IP alone has been analysed as a site-specific ectopic pregnancy (EP) in previous studies; however, according to the latest European Society of Human Reproduction and Embryology criteria, IP is classified as a tubal pregnancy. If IP can be classified as a tubal pregnancy, then there is no difference in the effects of these two methods on intrauterine pregnancies (IUPs).

Ralationship between polymorphisms and diplotypes of HLA-G 3'UTR and fetuses with abnormal chromosomes or unexplained pregnancy loss (UPL).

Objectives: Human leukocyte antigen G (HLA-G) plays a crucial role in pregnancy. Pregnancy loss (PL) is caused by a variety of causes, such as fetal chromosomal abnormalities, maternal hypertension and diabetes, immune causes, spontaneous immune diseases, infections, unknown causes, etc. This study reports on the association of fetal HLA-G 3'UTR polymorphisms and diplotypes with chromosomally abnormal fetuses (CAF) or unexplained pregnancy loss (UPL).

Impact of Omicron Variant Infection on Female Fertility and Laboratory Outcomes: A Self-Controlled Study.

Problem: Investigating the impact of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection on female fertility and laboratory outcomes in patients undergoing assisted reproductive technology (ART) treatment who were initially uninfected but later became infected.

Methods Of The Study: This self-controlled study included 197 patients who underwent repeated oocyte retrieval before and after SARS-CoV-2 infection between March 2021 and April 2023, of which 117 used the same ovarian stimulation protocol within a consistent age range. We evaluated the ovarian reserve, ovarian response, and laboratory outcomes in patients before and after SARS-CoV-2 infection.
