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.

Awareness of Infectious Disease Screening During Early Pregnancy and Knowledge About its Vertical Transmission in Japan: A Report from the Pregnant Women Health Initiative.

Objectives: We aimed to clarify the accuracy of pregnant women's knowledge and understanding regarding infectious disease screening in early pregnancy and clarify the roles that should be played by health care providers in promoting the health of pregnant women and their children.

Methods: A cross-sectional questionnaire survey was conducted in 25 hospitals across Japan from May 2018 to September 2019. We compared the agreement rates regarding screening results for hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis, human T-cell leukemia virus-1 (HTLV-1), and cervical cytology in the medical records and understanding of their results by pregnant women.

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.

Hysteroscopic resection with temporary balloon catheter occlusion of bilateral internal iliac arteries for managing retained products of conception after spontaneous abortion: Two cases report.

Retained products of conception (RPOC) is a condition in which trophoblastic tissue remains in the uterus after pregnancy, causing massive hemorrhage in some cases. Though RPOC is commonly treated by intrauterine curettage or hysteroscopic resection uterine artery embolization or hysterectomy may be performed in case of massive bleeding. We experienced two cases of RPOC after surgery for missed abortion that failed to respond to conservative treatment and required surgical treatment.

Influence of laparoscopic surgery for endometriosis and its recurrence on perinatal outcomes.

Purpose: It is unknown whether surgery for endometriosis or recurrence of endometriosis affects obstetric outcomes.

Methods: A total of 208 pregnant women with a history of endometriosis were analyzed. Patients who had endometriomas >3 cm and no history of laparoscopic surgery for endometriosis were defined as non-surgery group ( = 60), while those who had a history of surgery for endometriosis ( = 148) were defined as surgery group.

The first case of congenital syphilis diagnosed by 16S ribosome-RNA gene sequence analysis.

Syphilis infection during pregnancy causes perinatal complications and mother-to-child transmission if untreated. A newborn was delivered by emergent cesarean section due to non-reassuring fetal status at 34 weeks of gestation. The mother tested negative for rapid plasma reagin (RPR) and Treponema pallidum hemagglutination (TPHA) in early pregnancy.

Perinatal outcomes associated with the positional relationship between the placenta and the adenomyosis lesion.

Introduction: Although various perinatal complications have been reported to be increased in the pregnant patients with adenomyosis, it is not clear what type of patients with adenomyosis is more likely to cause obstetric complications. In this study, we focused on the positional relationship between the placenta and adenomyosis lesion in evaluating perinatal prognosis of pregnant patients with adenomyosis.

Material And Methods: This retrospective cohort study was carried out between 1 January 2005 and 31 December 2019 in a single institution.

Combination of conservative treatment and temporary bilateral laparoscopic uterine artery clipping with hysteroscopic transcervical resection for cervical pregnancy: A retrospective study.

Materials And Methods: This study is a retrospective clinical case series conducted at Teine Keijinkai Hospital from January 2014 to June 2019. Nine cervical pregnancies among 164 ectopic pregnancies were retrospectively examined.

Analysis of risk factors of postlaparoscopic shoulder pain.

Aim: Postlaparoscopic shoulder pain (SP), mainly caused by pneumoperitoneum with CO , sometimes suffers patients. This study was aimed to analyze the backgrounds of SP after gynecologic laparoscopy to clarify the risk of SP.

Methods: We analyzed answers of questionnaire about the degree of SP from 696 patients undergoing gynecologic laparoscopic surgery since 2014-2018.

Second-Generation -Phenolsulfonic Acid-Formaldehyde Resin as a Catalyst for Continuous-Flow Esterification.

A second-generation -phenolsulfonic acid-formaldehyde resin (PAFR II) catalyst was prepared by condensation polymerization of sodium -phenolsulfonate and paraformaldehyde in an aqueous HSO solution. This reusable, robust acid resin catalyst was improved in both catalytic activity and stability, maintaining the characteristics of the previous generation catalyst (-phenolsulfonic acid-formaldehyde resin). PAFR II was applied in the batchwise and continuous-flow direct esterification without water removal and provided higher product yields in continuous-flow esterification than any other commercial ion-exchanged acid catalyst tested.

This systematic review aimed to investigate complications related to initial trocar insertion among 3 different laparoscopic techniques: Veress needle (VN) entry, direct trocar entry (DTE), and open entry (OE). A literature search was completed, and complications were assessed. Major vessel injury, gastrointestinal injury, and solid organ injury were defined as major complications.

Successful treatment of uterine artery pseudoaneurysm with laparoscopic temporary clamping of bilateral uterine arteries, followed by hysteroscopic surgery.

Surgical strategies for the treatment of uterine artery pseudoaneurysm (UAP) include transarterial embolization and ultrasound-guided low-dose thrombin injection. Such strategies, however, have limitations and include the risk of ischemic damage to the uterus. We report a case of UAP treated with a new hysteroscopic and laparoscopic technique.

Genome-wide association studies identify PRKCB as a novel genetic susceptibility locus for primary biliary cholangitis in the Japanese population.

A previous genome-wide association study (GWAS) performed in 963 Japanese individuals (487 primary biliary cholangitis [PBC] cases and 476 healthy controls) identified TNFSF15 (rs4979462) and POU2AF1 (rs4938534) as strong susceptibility loci for PBC. In this study, we performed GWAS in additional 1,923 Japanese individuals (894 PBC cases and 1,029 healthy controls), and combined the results with the previous data. This GWAS, together with a subsequent replication study in an independent set of 7,024 Japanese individuals (512 PBC cases and 6,512 healthy controls), identified PRKCB (rs7404928) as a novel susceptibility locus for PBC (odds ratio [OR] = 1.

Aim: The present observational study aimed to clarify the effects of sleep disorders on threatened premature delivery, especially preterm uterine contraction.

Methods: The participants included 122 healthy singleton pregnant women. The Pittsburgh sleep quality index was used to evaluate the quality of sleep during the previous month at the initial examination and at 16, 24, and 32 weeks of gestation; scores >5 indicate poor sleep.

P53, hTERT, WT-1, and VEGFR2 are the most suitable targets for cancer vaccine therapy in HLA-A24 positive pancreatic adenocarcinoma.

Cancer vaccine therapy is one of the most attractive therapies as a new treatment procedure for pancreatic adenocarcinoma. Recent technical advances have enabled the identification of cytotoxic T lymphocyte (CTL) epitopes in various tumor-associated antigens (TAAs). However, little is known about which TAA and its epitope are the most immunogenic and useful for a cancer vaccine for pancreatic adenocarcinoma.

Rare case of peritoneal complete hydatidiform mole.

A 23-year-old woman, gravida 1, para 1, was transferred to our hospital with acute lower abdominal pain and vital signs consistent with shock. Her urine concentration of human chorionic gonadotrophin was 8000 mIU/mL. Transvaginal ultrasound revealed an echo-free space with mosaic echo pattern in the right adnexal area and no gestational sac in the uterus.

A case of aggressive angiomyxoma of the vulva.

Aggressive angiomyxoma (AA) is a rare mesenchymal neoplasm of the female pelvis and vulva, which has a tendency for local recurrence. AA is occasionally misdiagnosed as Bartholin's gland cyst or abscess, lipoma, simple labial cyst, or soft tissue tumors. We describe a case of AA on the outside of the left labium majus pudendi in a 28-year-old female.

Genome-wide association study identifies TNFSF15 and POU2AF1 as susceptibility loci for primary biliary cirrhosis in the Japanese population.
