Introduction: QT interval prolongation is a risk factor for fatal arrhythmias and other cardiovascular complications. QT interval prolongation in patients on hemodialysis (HD) is not well understood. Hypocalcemia is a suspected, but poorly verified etiology in these patients, and the association between serum phosphorus levels and QT interval prolongation is unknown.

Recently, it was hypothesized that PCOS patients may be at high risk of novel COVID-19 infections and worse clinical presentations during such infections. Here, we evaluated the effects of PCOS on stress responses to bacterial and viral mimetics using dihydrotestosterone-induced PCOS model rats.

To elucidate the clinical implications of SFRPs in uterine sarcoma, SFRP expression levels and their effects on uterine leiomyosarcoma cells were examined. Immunostaining for SFRP4 was performed on uterine smooth muscle, uterine fibroid and uterine leiomyosarcoma tissues.

Activin may therefore be involved in the development and proliferation of endometriotic cells via the SMAD signaling pathway. However, few detailed reports exist on SMAD7 expression in endometriosis.

However, few reports have described the effects of STAT inhibitors on endometriosis, another chronic inflammatory disease. Here, we investigated the intraperitoneal microenvironment and the effects of a STAT inhibitor in a mouse model of endometriosis.

A total of 123 unbiased patients with OC were tested for g and g using next-generation sequencing-based targeted amplicon sequencing. Clinical characteristics of OC patients with and without g status were compared.

Method: The present study included patients who underwent hemodialysis from June 1st 2016 to May 31st 2020.
Although endometrial cancer is extremely rare during pregnancy, the placental metastasis of endometrial cancer is even rarer. The current study presents a case of endometrial carcinoma that was diagnosed through the pathological examination of the placenta. A 35-year-old primipara woman who underwent frozen-thawed embryo transfer at the Keiai Ladies Clinic in Tokushima prefecture (Japan) received regular prenatal check-ups.

Methods: This is a secondary analysis of a previous multicenter retrospective study examining 906 women with stage I-IV UCS who underwent primary hysterectomy. Patient demographics, treatment types, tumor characteristics, and survival were examined across aged ≥80 (n = 82 [9.
Resveratrol, a natural product and peroxisome proliferator-activated receptor (PPAR) agonist, has been reported to exert anti-cancer effects in several tumor models. A previous study by our group reported that prostaglandin J2, a PPARγ ligand, inhibited cell proliferation in a uterine sarcoma cell line. The aim of the present study was to investigate the role of the Wnt signaling pathway in resveratrol-induced apoptosis and inhibition of cell proliferation in the MES-SA human uterine sarcoma cell line.

Objective- Angiogenesis, entire step from endothelial cells (ECs) sprouts to vascular maturation, is a critical response to ischemia. To form functional mature vessels, interactions between ECs and pericytes are essential. Ninj1 (ninjurin1) is an adhesion molecule that contributes to the pathogenesis of neuroinflammation.

We retrospectively evaluated their clinical records and histopathological factors.
View Article and Find Full Text PDFObjective: To examine significance of sarcoma dominance (SD) patterns in uterine carcinosarcoma (UCS).
Methods: This is a secondary analysis of multicenter retrospective study examining women with stages I-IV UCS who underwent primary surgery. SD was defined as >50% of sarcoma component in uterine tumor.
Aim: Type Ⅲ collagen abundantly exists in the cardiovascular system, including the aorta and heart. We prospectively investigated whether serum levels of aminoterminal propeptide of type Ⅲ procollagen (PⅢNP), a circulating biomarker of cardiovascular fibrosis, could predict cardiovascular events in patients undergoing hemodialysis.
Methods: Serum PⅢNP concentrations were measured in 244 patients undergoing maintenance hemodialysis (men, 126; women, 118; mean age, 64±11 years; dialysis duration, 11.
Purpose: To propose a categorization model of uterine carcinosarcoma (UCS) based on tumor cell types (carcinoma and sarcoma) and sarcoma dominance.
Methods: This secondary analysis of a prior multicenter retrospective study examined 889 cases of UCS with available histologic evaluation. Based on survival outcome, cases were clustered into three groups: low-grade carcinoma with nondominant homologous sarcoma [type A, n = 96 (10.
Background: Recent lines of evidence suggest that, as in other countries, sudden cardiac death (SCD) is more common in the Japanese dialysis clinical setting than we previously thought.
Summary: Three specific important findings may underlie the increased incidence of SCD in dialysis patients. Even after successful coronary revascularization, hemodialysis (HD) patients continue to have a higher incidence of SCD than the general population.
Case: Approximately 3%-25% of cases of endometrial carcinoma (EC) or atypical endometrial hyperplasia (AH) occur in women aged <40 years and conservative treatment with high-dose medroxyprogesterone acetate (MPA) is administered to women who wish to preserve their fertility. Here is reported the pregnancy outcomes of patients with EC or AH who received MPA therapy at Tokushima University Hospital, Tokushima, Japan. The frequency of pregnancy and live births among the patients with EC or AH who received conservative treatment, followed by fertility treatment, were analyzed retrospectively.
