Impact of previous cesarean delivery on pregnancy and neonatal outcomes in subsequent in vitro fertilization/intracytoplasmic sperm injection and single frozen-thawed embryo transfer: a historical cohort study with a large sample size.

Purpose: This study aims to explore the impact of a woman's previous cesarean delivery (CD) on pregnancy and neonatal outcomes for subsequent in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) and single frozen-thawed embryo transfer (FET), compared with vaginal delivery (VD).

Methods: This was a retrospective cohort study that included a total of 5817 patients who desired to transfer a single vitrified-thawed blastocyst from the same oocyte retrieval cycle as their last live birth between January 2011 and January 2021 at a single reproductive medicine center. Patients with a single previous CD were classified in the CD group, while those with a single VD were assigned to the VD group.

No Association of Polycystic Ovary Syndrome with Pancreatic Cancer: A Mendelian Randomization Study.

Unlabelled: Recently, there has been a debate regarding the association between polycystic ovary syndrome (PCOS) and pancreatic cancer (PC). In order to examine the causal relationship between PCOS and PC, we conducted a Mendelian randomization study, which utilized 12 single nucleotide polymorphisms (SNPs) identified from a genome-wide association study (GWAS) meta-analysis that included 10,074 PCOS cases and 103,164 controls of European ancestry as instrumental variables (IVs). The outcome data were obtained from the FinnGen database (including 605 cases and 218,187 controls).

Cold scissors ploughing technique versus electrosurgical excision for hysteroscopic adhesiolysis: a multicenter randomized controlled trial.

Intrauterine adhesions (IUA) may lead to abnormal menstruation, infertility, and pregnancy-related complications. Hysteroscopic separation is the gold standard treatment for IUA and can be performed using a variety of instruments and methods, including cold scissors and electrotomy. However, it is unclear which method is more effective for relieving IUA, restoring uterine anatomy, and improving the pregnancy rate in women of childbearing age.

Can ferroptosis be a target for reproductive health?

Ferroptosis has been implicated in several reproductive disorders, but the underlying mechanisms remain unknown; thus, interventions targeting this pathway are lacking. Here we summarize the emerging findings on ferroptosis in reproductive biology and corresponding disorders, and highlight perspectives and challenges on future ferroptosis research with potential clinical applications.

Bisphenol S impairs oocyte quality by inducing gut microbiota dysbiosis.

Unlabelled: A good quality egg is essential for a successful pregnancy and early embryo development. Oocyte development is vulnerable to environmental exposures. Bisphenol S (BPS) is widely used as a replacement for its analog bisphenol A, but the reproductive toxicity of BPS has been of great concern.

Investigating Aging-Related Endometrial Dysfunction Using Endometrial Organoids.

Ageing of the endometrium is a critical factor that affects reproductive health, yet its intricate mechanisms remain poorly explored. In this study, we performed transcriptome profiling and experimental verification of endometrium and endometrial organoids from young and advanced age females, to elucidate the underlying mechanisms and to explore novel treatment strategies for endometrial ageing. First, we found that age-associated decline in endometrial functions including fibrosis and diminished receptivity, already exists in reproductive age.

Context: Renal function may play a crucial role in the development of gestational diabetes mellitus (GDM). However, prospective studies on this topic are scarce and the mechanisms remain unclear.

Objective: To assess the associations of early-pregnancy renal function with GDM and the mediating role of carnitine metabolites.

Rare cases of a second recurrence of nephroblastoma with MLLT1 gene mutation: case report and literature review.

Nephroblastoma or Wilms tumor is the most common tumor of the urinary system in childhood. The survival rate can reach more than 90% after multidisciplinary treatment, but there is still a certain recurrence rate. In recent years, domestic and foreign scholars have analyzed the gene mutations related to the recurrence of nephroblastoma from the genetics or epigenetics perspective.

S100A11 promotes lipid metabolism and activates the apoptosis in polycystic ovary syndrome.

Apoptosis of ovarian granulosa cells (GCs) affects the development and maturation of oocyte in Polycystic ovary syndrome (PCOS).The objective of our study was to examine the impact of S100A11 on granulosa cells in individuals with polycystic ovary syndrome. We found that the S100A11 level was higher in the ovarian granulosa cells of PCOS patients and ovarian tissue of PCOS mouse models.

Sialidase NEU3 silencing inhibits angiogenesis of EA.hy926 cells by regulating Wnt/β-catenin signaling pathway.

Angiogenesis significantly drives tumor progression, and the functions of vascular endothelial cells are influenced by various factors. Tumor cells are characterized by abnormal sialylation, and their dynamic balance depends on sialyltransferases and sialidases. NEU3 is a plasma membrane-associated sialidase, vital for the regulation of cell surface sialylation.

Screening and verification of differentially expressed serum proteins in children with severe adenovirus pneumonia.

Background: Human adenoviruses are prevalent pathogens that cause severe acute respiratory infections. The clinical presentation of the adenoviral pneumonia is varied; in severe cases, they may cause systemic multi-system damages. Currently, early clinical differential diagnosis is difficult under the existing testing methods, the study identified potential biomarkers by screening and validating differentially expressed proteins (DEPs), and aimed at distinguishing between severe and non-severe adenovirus pneumonia in children aged <14 years.

Embryo Cryopreservation Strategy May Improve Live Birth for Women Underwent In Vitro Maturation After Early Oocyte Retrieval: A Retrospective Cohort Study.

There is limited clinical research investigating the optimal transplantation strategy in early oocyte retrieval cycles. We aimed to assess whether the maturation of oocytes from early oocyte retrieval influenced pregnancy outcomes, and to find the optimal embryo transfer strategy (fresh or frozen-thawed embryo transfers) for patients who had early oocyte retrieval and underwent in vitro maturation (IVM). A retrospective cohort study was conducted in a university-based reproductive medical center.

VIM-AS1, which is regulated by CpG methylation, cooperates with IGF2BP1 to inhibit tumor aggressiveness via EPHA3 degradation in hepatocellular carcinoma.

Early tumor recurrence in hepatocellular carcinoma (HCC) remains a challenging area, as the mechanisms involved are not fully understood. While microvascular invasion is linked to early recurrence, established biomarkers for diagnosis and prognostication are lacking. In this study, our objective was to identify DNA methylation sites that can predict the outcomes of liver cancer patients and elucidate the molecular mechanisms driving HCC aggressiveness.

Monocyte-derived extracellular vesicles, stimulated by Trypanosoma cruzi, enhance cellular invasion in vitro via activated TGF-β1.

During cell invasion, large Extracellular Vesicle (lEV) release from host cells was dose-dependently triggered by Trypanosoma cruzi metacyclic trypomastigotes (Mtr). This lEV release was inhibited when IP-mediated Ca exit from the ER and further Ca entry from plasma membrane channels was blocked, but whilst any store-independent Ca entry (SICE) could continue unabated. That lEV release was equally inhibited if all entry from external sources was blocked by chelation of external Ca points to the major contributor to Mtr-triggered host cell lEV release being IP/store-mediated Ca release, SICE playing a minor role.

Kidney function mediates the effects of four per-and polyfluoroalkyl substances (PFAS) on atherosclerotic cardiovascular disease.

Background: PFAS pose a significant threat to cardiovascular health and increase the risk of atherosclerotic cardiovascular disease (ASCVD). However, there is limited research evidence regarding the mechanisms by which PFAS affect the risk of ASCVD and the exposure-risk (E-R) relationship. The effect of kidney function in the relationship between PFAS and ASCVD risk has not been adequately validated.
