Five hundred and fifty-six pregnant women underwent examinations of FS, Nugent score-a Gram-staining scoring system for the diagnosis of bacterial vaginosis (BV)-and conventional bacterial culture between 8 weeks and 12 gestational weeks. Nugent scores of 0-3, 4-6, and ≥7 were found in 469 (84.

Effect of a FOXO1 inhibitor on trophoblast differentiation from human pluripotent stem cells and ERV-associated gene expression.

Introduction: In human placental development, the trophectoderm (TE) appears in blastocysts on day 5 post-fertilization and develops after implantation into three types of trophoblast lineages: cytotrophoblast (CT), syncytiotrophoblast (ST), and extravillous trophoblast (EVT). CDX2/Cdx2 is expressed in the TE, and Cdx2 expression is upregulated by knockdown of Foxo1 in mouse ESCs. However, the significance of FOXO1 in trophoblast lineage differentiation during the early developmental period remains unclear.

Collagen patches releasing phosphatidylserine liposomes guide M1-to-M2 macrophage polarization and accelerate simultaneous bone and muscle healing.

Bilateral communication between bones and muscles is essential for healing composite bone-muscle injuries from orthopedic surgeries and trauma. However, these injuries are often characterized by exaggerated inflammation, which can disrupt bone-muscle crosstalk, thereby seriously delaying the healing of either tissue. Existing approaches are largely effective at healing single tissues.

Effectiveness of Laparoscopic Adenomyomectomy on Perinatal Outcomes.

Objectives: The objective of this study was to observe the influence of laparoscopic adenomyomectomy on perinatal outcomes.

Materials And Methods: The retrospective cohort study included 43 pregnant cases with adenomyosis who did not undergo laparoscopic surgery before pregnancy (nonsurgery group; 26 cases) and did (surgery group; 17 cases). To evaluate the impact of surgery on perinatal outcomes, nine obstetric complications including preterm delivery, hypertensive disorder of pregnancy, placental malposition, oligohydramnios, gestational diabetes mellitus, uterine rupture, abruptio placentae, and postpartum hemorrhage were selected.

Toxoplasma gondii IgG avidity for the diagnosis of primary infection in pregnant women: Comparison between chemiluminescent microparticle immunoassay and enzyme-linked immunosorbent assay.

Introduction: This study evaluated whether IgG avidity measured by chemiluminescent microparticle immunoassay (CMIA) compared with enzyme-linked immunosorbent assay (ELISA) was useful to detect primary T. gondii infection during pregnancy and to estimate the risk for congenital T. gondii infection.

Association of anti-β2-glycoprotein I/HLA-DR complex antibody with arterial thrombosis in female patients with systemic rheumatic diseases.

Background: β2-glycoprotein I (β2GPI) complexed with human leukocyte antigen DR (β2GPI/HLA-DR) was found to be a major autoantibody target in antiphospholipid syndrome (APS). This study aimed to reveal the association between anti-β2GPI/HLA-DR antibodies and vascular thromboses in women with systemic rheumatic diseases.

Methods: We conducted a retrospective longitudinal study.

Chronic Endometritis and Uterine Endometrium Microbiota in Recurrent Implantation Failure and Recurrent Pregnancy Loss.

The aim of this study was to evaluate whether chronic endometritis (CE) and uterine endometrium microbiota were associated with repeated implantation failures (RIFs) and recurrent pregnancy losses (RPLs). In this prospective study, uterine endometrial specimens were obtained from 24 women with RIF, 27 with RPL, and 29 fertile control women. Immunohistochemical staining of CD138 for CE and 16S ribosomal RNA (rRNA) sequencing analysis for uterine endometrium microbiota were performed simultaneously.

Increased IL-10-competent regulatory B cells in the decidua of early human pregnancy.

Regulatory B cells (Bregs) may play a pivotal role in maintaining human pregnancy. For the first time, to the best of our knowledge, this study noted that cell percentages of CD24CD38 Bregs and CD24CD27 Bregs, which can potentially produce IL-10, are increased in human decidua compared with the mid-luteal phase endometrium. In each case of decidua, the correlation between Bregs and dendritic cell (DC) or natural killer (NK) cell expression was further explored.

Anti-β2-glycoprotein I/HLA-DR Antibody and Adverse Obstetric Outcomes.

Anti-β2-glycoprotein I/HLA-DR (anti-β2GPI/HLA-DR) antibody has been reported to be associated with antiphospholipid syndrome and recurrent pregnancy loss (RPL). We conducted a prospective multicenter cross-sectional study aimed at evaluating whether the anti-β2GPI/HLA-DR antibody is associated with adverse obstetric outcomes and RPL. From 2019 to 2021, serum anti-β2GPI/HLA-DR antibody levels (normal, <73.

Anti-β2-glycoprotein I/HLA-DR antibody in infertility.

To evaluate whether anti-β2-Glycoprotein I/HLA-DR (anti-β2GPI/HLA-DR) antibody is associated with pathophysiology of infertility, 224 women with infertility were enrolled from July 2020 to December 2021 in this prospective study. The serum levels of anti-β2GPI/HLA-DR antibody (normal < 73.3 U) were determined in 224 women with infertility.

The Factors Influencing Pregnant Women's Selection of Media Sources to Obtain Information on COVID-19 in Japan in 2021.

Pregnant women presumably gather information about the coronavirus disease 2019 (COVID-19) from various sources. However, it is difficult for pregnant women who are not medical professionals to source the appropriate information because of the infodemic related to the COVID-19 pandemic. Therefore, the objective of our study was to investigate how pregnant women gathered information about COVID-19 and COVID-19 vaccination.

Influence of Uterine Cavity Breach in Laparoscopic Myomectomy on the Risk of Obstetric Complications.

Objectives: Prepregnancy myomectomy is effective for the treatment of infertility or prevention of obstetric complications and is usually performed with laparoscopy. However, pregnancies following myomectomy have risks of obstetric complications, especially in cases with uterine cavity breaches, but the evidence remains unclear. We investigated how uterine cavity breach in laparoscopic myomectomy influenced the occurrence of obstetric complications.

The Current Challenges in Developing Biological and Clinical Predictors of Congenital Cytomegalovirus Infection.

Congenital cytomegalovirus (CMV) infection may cause severe long-term sequelae. Recent studies have demonstrated that early antiviral therapy for infants with symptomatic congenital CMV (cCMV) infection may improve neurological outcomes; thus, accurate identification of newborns at high risk of cCMV infection may contribute to improved outcomes in affected children. However, maternal serological screening for cCMV infection by diagnosing primary infection during pregnancy, which is a popular screening strategy, is inefficient, because the number of cCMV infections with nonprimary causes, including reactivation of or reinfection with CMV, is larger than that of cCMV infections with primary causes.
