Efficacy of ultrasound-indicated cerclage without prior preterm birth.

Aim: Our study aimed to evaluate the effectiveness of ultrasound-indicated cerclage in singleton pregnancies with cervical shortening (<25 mm), excluding those with a history of preterm birth (PTB) and infection/inflammation.

Materials And Methods: Among the 1556 women admitted for a cervix measuring <25 mm via transvaginal ultrasound at Juntendo University Urayasu Hospital between January 2001 and December 2023, our study focused on 47 singleton patients with no prior history of PTB. After receiving information on both risks and benefits, 25 patients opted for ultrasound-indicated cerclage (cerclage group), while 22 chose expectant management (expectant management group).

Activation of peripheral leukocyte migration before spontaneous labor at term.

Background: Leukocytes are induced to migrate into the uterus at parturition, releasing cytokines and chemokines that activate it for delivery. A specific chemotactic signal is required for these actions, and published evidence suggests that it comes from the human fetal membranes and has a time-dependent component (ie, cells obtained at term in labor migrate more than cells obtained at term not yet in labor). The hypothesis that the fetal membrane chemoattractants activate the leukocytes to become responsive for migration was tested.

The importance of social oocyte cryopreservation in supporting local municipalities: A prospective study.

Background: With the trend toward late marriages and late childbearing, cryopreservation of oocytes for fertility preservation is attracting attention as a method to counteract the declining birthrate.

Objectives: To examine the impact of social oocyte cryopreservation on local communities by assessing the significance of government assistance for cryofreezing and capturing the participants' subsequent feelings regarding this assistance.

Design: Descriptive study.

Risk factors for resignation from work during pregnancy among Japanese women: a cross-sectional, multicenter questionnaire survey.

This study was to investigate the employment status of pregnant women in Japan and identify risk factors associated with resigning from work during pregnancy. We conducted a cross-sectional survey with 975 postpartum women in Tokyo and its suburbs, focusing on those who were employed during pregnancy. Women who were employed when they became pregnant were selected and divided into two groups: those who did not resign and those who resigned; the groups were analyzed separately.

Low serum carnitine level is associated with increased urinary carnitine excretion in late pregnancy.

Background: Carnitine is essential for fatty acid metabolism. Free carnitine (FCA) is excreted in the urine in the glomerulus, but is partly reabsorbed by a carnitine transporter. The mechanism underlying the decrease in serum carnitine level during pregnancy is unclear.

A Case of a Refractory Bleeding Giant Vaginal Wall Cavernous Hemangioma Successfully Managed with Sclerotherapy.

BACKGROUND Vaginal wall hemangiomas are extremely rare, benign, vascular tumors of the female genitalia. Most cases occur in childhood, but a few cases can be acquired; however, the mechanism of hemangioma formation remains unknown. Most hemangiomas involving female genital organs are small and asymptomatic.

The management of women of childbearing age with rheumatoid arthritis: an expert report.

Introduction: The introduction of biologic therapies and a treat-to-target approach has transformed the management of rheumatoid arthritis (RA), which has led to improved outcomes for women with RA who wish to become pregnant. However, guidelines for the management of reproductive health in female patients with RA are still lacking.

Areas Covered: A task force (Women of Childbearing Age [WoCBA]-Rheumatoid Arthritis in Japan) comprising 10 experts in the fields of rheumatology, obstetrics and orthopedic surgery developed 10 clinical questions (CQ) related to the management of WoCBA with RA.

Lipoprotein lipase concentration in umbilical cord blood reflects neonatal birth weight.

Background: Insulin resistance (IR) is exacerbated during pregnancy via increases in insulin counterregulatory hormones. Maternal lipids are strong determinants of neonatal growth, although triglyceride-rich lipoproteins (TGRLs) cannot be transferred directly to the fetus through the placenta. The catabolism of TGRLs under physiological IR and the reduced synthesis of lipoprotein lipase (LPL) are poorly understood.

Cervical Cerclage to Prevent Intrauterine Balloon Prolapse.

Intrauterine balloon prolapse sometimes occurs, and the intrauterine balloon must be reinserted. Furthermore, intrauterine balloon tamponade (IBT) failure can necessitate additional invasive procedures. We report a case of cervical cerclage with IBT for placenta previa with a cervical dilation.

Distal arthrogryposis in a girl arising from a novel TNNI2 variant inherited from paternal somatic mosaicism.

TNNI2 at 11p15.5 encodes troponin I2, fast skeletal type, which is a member of the troponin I gene family and a component of the troponin complex. Distal arthrogryposis (DA) is characterized by congenital limb contractures without primary neurological or muscular effects.

Guidelines for obstetrical practice in Japan: Japan Society of Obstetrics and Gynecology and Japan Association of Obstetricians and Gynecologists 2020 edition.

The 2017 clinical guidelines for obstetrical practice by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists were revised and published as the 2020 edition (in Japanese). The aim of these guidelines is to present appropriate standard obstetric diagnosis and management procedures that have reached consensus among Japanese obstetricians. The 2020 guidelines include 113 clinical questions and an appendix, followed by answers (CQ&A; originally 112 in the 2017 edition), a discussion, list of references, and some tables and figures presenting common problems and questions encountered in obstetrical practice.

Pathogenic variants detected by RNA sequencing in Cornelia de Lange syndrome.

Recent studies suggest that transcript isoforms significantly overlap (approximately 60%) between brain tissue and Epstein-Barr virus-transformed lymphoblastoid cell lines (LCLs). Interestingly, 14 cohesion-related genes with variants that cause Cornelia de Lange Syndrome (CdLS) are highly expressed in the brain and LCLs. In this context, we first performed RNA sequencing of LCLs from 22 solved (with pathogenic variants) and 19 unsolved (with no confirmed variants) CdLS cases.

An infant of 26 weeks gestation with congenital miliary tuberculosis complicated by chronic lung disease requiring CPAP was diagnosed on Day 104 of life: congenital tuberculosis was confirmed by detection of calcified ovaries in his mother.

Introduction: Early diagnosis of tuberculosis (TB) in infants is important but is commonly missed because the symptoms are often non-specific.

Case Presentation: A Nepalese male infant born at 26 weeks gestation and weighing 1227 g (97th centile) was admitted to the neonatal intensive care unit (NICU) immediately after birth for the management of his prematurity. After extubation on Day 8, his oxygen saturation became unstable and he required nasal continuous positive airway pressure with oxygen for 3 months.

The retrospective study for effectiveness of cervical cerclage in preventing recurrent preterm birth.

Objective: This study aimed to clarify the effectiveness of cervical cerclage in preventing recurrent preterm births.

Materials And Methods: A retrospective study was conducted using the perinatal registration database of the Japan Society of Obstetrics and Gynecology for the Perinatal Center from 2014 to 2016. The efficacies of history-indicated, ultrasound-indicated, and physical examination-indicated cerclage as preventive treatments for women with a history of preterm birth were evaluated by comparing cerclage and non-cerclage cases.

Probiotics including Clostridium butyricum, Enterococcus faecium, and Bacillus subtilis may prevent recurrent spontaneous preterm delivery.

Aim: A large cohort study of Japanese women reported that the rate of recurrent spontaneous preterm delivery (sPTD) in the next pregnancy was 22.3%; therefore, it is important to prevent recurrent sPTD. The present study investigated the rate of recurrent sPTD in pregnant women treated with probiotics.

Chronic active Epstein-Barr virus-associated secondary hemophagocytic lymphohistiocytosis in pregnancy: a case report.

Background: Secondary hemophagocytic lymphohistiocytosis (sHLH) is a rare and fatal disease characterized by uncontrolled immune cell activation that can lead to a cytokine storm. Unfortunately, this condition can occur even during pregnancy, threatening both maternal and fetal lives.

Case Presentation: A 23-year-old nulliparous woman at 26 weeks of gestation presented with continuous fever, coughing, and sore throat.

Fetal growth restriction as the initial finding of preeclampsia is a clinical predictor of maternal and neonatal prognoses: a single-center retrospective study.

Background: Preeclampsia (PE) is a hypertensive disorder specific to pregnancy that can cause severe maternal-neonatal complications. The International Society for the Study of Hypertension in Pregnancy revised the PE criteria in 2018; a PE diagnosis can be established in the absence of proteinuria when organ or uteroplacental dysfunction occurs. The initial findings of PE (IFsPE) at the first diagnosis can vary considerably across patients.

"Step-by-Step" Minimally Invasive Hemostatic Technique Using Intrauterine Double-Balloon Tamponade Combined with Uterine Isthmus Vertical Compression Suture for the Control of Placenta Accreta and Severe Atonic Hemorrhage during a Cesarean Section.

A sudden onset of postpartum hemorrhage (PPH) during a cesarean delivery requires urgent hemostasis procedures, such as the B-Lynch, Hayman, or double-vertical compression sutures, when bimanual compression, uterotonic agent administration, and intrauterine balloon tamponade had failed to achieve sufficient hemostasis. However, after invasive hemostatic procedures, postoperative complications, including subsequent synechiae and infection followed by ischemia, have been reported to occur even in successful cases. To avoid these complications, we devised and performed a minimally invasive combined technique based on a "step-by-step" minimally invasive hemostatic protocol for a case of placenta accreta and severe atonic hemorrhage during a cesarean delivery.
