PurposeTo evaluate the association between benzodiazepine exposure during early pregnancy and the risk of miscarriage, with a focus on dose-response, half-life, and individual agents.MethodsThis nested case-control study was conducted using…

Abstract Purpose Ovarian clear cell carcinoma (OCCC) is strongly associated with endometriosis and shows geographic variation in incidence. We investigated whether OCCC and adjacent endometriosis exhibit distinct transcriptional states and …

This study investigates the association between parity and type 2 diabetes mellitus (T2DM) in Japanese women, considering the clinical history of gestational diabetes mellitus (GDM) and menopausal status, which are known risk factors for T2…

ObjectivesThis study aimed to investigate the association and population-attributable fraction (PAF) of maternal smoking and secondhand smoke (SHS) exposure during pregnancy with placental abruption.DesignProspective cohort study.Setting15 …

This study investigated the association of parity with hypertension prevalence in Japanese women while considering a clinical history of hypertensive disorders of pregnancy (HDP) and menopausal status. This cross-sectional study included 30…

The initiation of human pregnancy is marked by the implantation of an embryo into the uterine environment; however, the underlying mechanisms remain largely elusive. To address this knowledge gap, we developed hormone-responsive endometrial…

BackgroundGlobal studies exploring the relationship between parity and chronic kidney disease (CKD) are scarce. Furthermore, no study has examined the relationship between parity and CKD in Japan. Therefore, this study aimed to examine the …

OBJECTIVES: Although atypical endometrial hyperplasia (AEH) is considered a precancerous disease, the frequency with which AEH and endometrial cancer (EC) coexist is not low. Broadly, total laparoscopic hysterectomy (TLH) is performed for t…

PurposeTo analyze whether response to the GnRH test is a predictor of empty follicle syndrome (EFS) and to analyze independent risk factors for EFS.MethodsThe GnRH test results of 3765 patients from 2016 to 2018 were used to define the refe…

An 81-year-old man with a history of prostate cancer developed sciatica and underwent L4/5 laminectomy followed by L5/S1 transforaminal lumbar interbody fusion. Postoperatively, pain improved temporarily, then deteriorated. Tumor resection …

This study examines the association between abnormal cervical cytology and subjective health in pregnant women, as an adjunct to the Japan Environment and Children's Study, which cross-sectionally analyzed a subset of the prospective cohort…

PurposeThe purpose of this study was to evaluate the usefulness of turbo spin-echo (TSE) DWI with fusion images in the T-staging compared with T2-weighted imaging (T2WI) alone and conventional echo-planner imaging (EPI) DWI.MethodsIn this p…

Ovarian clear cell carcinoma (OCCC) exhibits distinct phenotypes, such as resistance to chemotherapy, poor prognosis and an association with endometriosis. Biomarkers and imaging techniques currently in use are not sufficient for reliable d…

We studied the whole-genome point mutation and structural variation patterns of 133 tumors (59 high-grade serous (HGSC), 35 clear cell (CCOC), 29 endometrioid (ENOC), and 10 adult granulosa cell (GCT)) as a substrate for class discovery in …

Polypoid endometriosis is a distinctive variant of endometriosis with histological features simulating those of endometrial polyps. Müllerianosis is characterized by the presence of lesions at any site containing admixtures of endosalpingio…

OBJECTIVE: Ovarian clear cell carcinoma (OCCC) frequently presents at an early stage. In stage I OCCC, the prognosis differs according to substage. In particular, predictive biomarkers and new treatment strategies are needed for stage IC2/I…

Previous studies have identified microRNA (miRNA) involvement in human cancers. This study aimed to elucidate potential clinical and biological associations of ovarian cancer-related miRNA gene expression profiles in high-grade serous carci…

When compared with other epithelial ovarian cancers, the clinical characteristics of ovarian clear cell adenocarcinoma (CCC) include 1) a higher incidence among Japanese, 2) an association with endometriosis, 3) poor prognosis in advanced s…

BACKGROUND: Epithelial ovarian cancer (EOC) is the most common cause of gynecological malignancy-related mortality. Ovarian clear cell carcinoma (CCC) has unique clinical characteristics and behaviors that differ from other histological typ…

PurposeThe precise mechanism causing outer retinal damage in acute macular neuroretinopathy (AMN) remains unclear. In this study, choroidal blood flow velocity was quantitatively evaluated using laser speckle flowgraphy (LSFG) in a patient …

We previously reported that indoleamine-2,3-dioxygenase (IDO) is associated with paclitaxel resistance and that IDO serves as a marker of poor prognosis in ovarian serous adenocarcinomas (SA). In this study, to explore the role of IDO in th…

A new efficient screening for ovarian cancer based on a combination of two tumor markers, CA602 and CA546, is reported. These two tumor markers can be detected by a combination immunoenzymometric assay of these two antigens. This combinatio…

Granulosa cell tumors derived from sexcord-stromal cells are thought to be generally estrogen producing neoplasms. However recent reports show that these common epithelial tumors, adenocarcinomas and Brenner tumors, are capable of estrogen …
