sFlt-1/PlGF ratio predicts serious outcomes in confirmed early-onset preeclampsia.

Objectives: We aimed to determine whether a high ratio of soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) would be associated with serious negative consequences and shorter pregnancy duration in cases of early-onset preeclampsia (PE).

Study Design: This retrospective cohort study included women (n = 65) diagnosed with PE at <34.0 weeks of gestation and recruited from a single primary and tertiary medical centre in Japan.

Preeclampsia prediction model using demographic, clinical, and sonographic data in the second trimester of Japanese nulliparous women.

Aim: This study aimed to clarify the factors influencing preeclampsia (PE) development in nulliparous Japanese women and to develop a PE prediction model using second trimester sonographic and clinical data readily available to obstetricians.

Methods: This historical cohort study examined the obstetric records of nulliparous women who delivered at Yamanashi Prefectural Central Hospital from January 2019 to May 2023. A model was constructed to predict the PE development rate, with a focus on 796 nulliparous women.

Utility of the angle between the cervical canal and the anatomical conjugate line for predicting pouch of Douglas obliteration in patients with posterior placenta previa.

Aim: Pouch of Douglas obliteration, which prevents exteriorization of the uterus, increases surgical morbidity in patients with placenta previa. We aimed to identify magnetic resonance imaging features that can predict pouch of Douglas obliteration preoperatively.

Methods: We retrospectively assessed 39 women with posterior placenta previa who underwent magnetic resonance imaging for the preoperative assessment of placenta accreta spectrum.

Association between α-defensin 5 and the expression and function of P-glycoprotein in differentiated intestinal Caco-2 cells.

α-Defensin 5 is known to be secreted by Paneth cells in the small intestine and plays an important role in eliminating pathogenic microorganisms. It has been reported that a decrease in α-defensin 5 level in the human small intestine is a risk of inflammatory bowel disease (IBD). Furthermore, P-glycoprotein (P-gp), a member of the ATP-binding cassette transporter superfamily, encoded by the ABCB1/MDR1 gene, plays an important role in the front line of host defense by protecting the gastrointestinal barrier from xenobiotic accumulation and may contribute to the development and persistence of IBD.

A modified transabdominal cervicoisthmic cerclage with the monofilament thread: Its efficacy and safety for women with extremely short cervix due to cervical conization.

Aim: The study aimed to examine the usefulness of modified transabdominal cervicoisthmic cerclage (TAC) using monofilament thread for the prevention of preterm delivery in women with an extremely short cervix after deep conization.

Methods: We devised a monofilament thread for picking up the seromuscular layer of the site that is slightly cephalad to the internal ostium to prevent injury of the vessels around the uterine cervix. From 2017 to 2020, we performed this modified operation in eight women (nine pregnancies) at 12-16 weeks of gestation with a history of deep cervical conization.

Predictive value of the sFlt-1/PlGF ratio for preeclampsia in twin pregnancies: a retrospective study.

: This study aimed to investigate the efficiency of the soluble Fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio in predicting preeclampsia (PE) within 4 weeks in twin pregnancies.: Seventy-eight women with serum angiogenic markers measured at 28 + 0 to 30 + 6 weeks of gestation were enrolled. A receiver-operating characteristic curve was used to determine the sFlt-1/PlGF ratio threshold to predict PE.

Analysis of α-Defensin 5 Secretion in Differentiated Caco-2 Cells: Comparison of Cell Bank Origin.

α-Defensin 5 has a particularly broad antibacterial spectrum; it eliminates pathogenic microorganisms and regulates intestinal flora. Although Caco-2 cells are similar to small intestinal cells, it is unclear whether they secrete α-defensin 5. Therefore, we investigated whether Caco-2 cells secrete α-defensin 5 and determined the secretion mechanism using cells from three cell banks (ATCC, DSMZ, and RIKEN).

Gamma-Aminobutyric Acid (GABA) Attenuates Ischemia Reperfusion-Induced Alterations in Intestinal Immunity.

The aims of this study were to determine the effects of gamma-aminobutyric acid (GABA) on immunoglobulin A (IgA) secretion from Peyer's patch (PP) cells; to assess rat alpha-defensin-5 (RD-5) expression in the rat small intestine; and to determine the effect of GABA on intestinal ischemia reperfusion (I/R) injury-induced intestinal innate immunity. We found that GABA caused an increase in IgA secretion in the presence and absence of lipopolysaccharide (LPS). Moreover, GABA also significantly increased the mRNA levels of RD-5 and superoxide dismutase (Sod) 1, 3.
