AIM: The refinement of assisted reproductive technology, including the development of cryopreservation techniques (vitrification) and ovarian stimulation protocols, makes frozen embryo transfer (FET) an alternative to fresh ET and has contributed to the success of assisted reproductive technology. Compared with fresh ET cycles, FET cycles were associated with better in vitro fertilization outcomes; however, the occurrence of pregnancy-induced hypertension, preeclampsia, and placenta accreta spectrum (PAS) was higher in FET cycles...

AIM: Ovarian surveillance in women with hereditary breast and ovarian cancer who do not undergo risk-reducing salpingo-oophorectomy has been controversial. Therefore, this study aimed to demonstrate the clinical features of ovarian surveillance at our institution using a technique that combines serum cancer antigen 125 measurements, transvaginal ultrasonography, and uterine endometrial cytology. METHODS: We retrospectively examined 65 women, who had not undergone risk-reducing salpingo-oophorectomy diagnosed with hereditary breast and ovarian cancer between 2000 and 2021 at our hospital...

AIM: Some concerns exist that diagnosis of gestational diabetes mellitus (GDM) may be missed when the simplified diagnostic criteria of the Japanese Society of Diabetes and Pregnancy (JSDP) for GDM (published during the COVID-19 pandemic) are used. Moreover, limited data is available regarding how widespread these diagnostic criteria are used when managing GDM during the COVID-19 pandemic. Therefore, this study aimed to determine how GDM diagnosis has changed during the COVID-19 pandemic in Japan...

OBJECTIVE: To investigate the value of ultrasound parameters in assessing the efficacy of transabdominal ultrasound (TAUS)-guided suction curettage alone for cesarean scar pregnancy (CSP). METHODS: Secondary retrospective analysis of a prospective study consisted of 137 women diagnosed with CSP who were performed TAUS-guided suction curettage alone for the first time at Maternity and Child Health Care of Guangxi Zhuang Autonomous Region in China. Prior to surgery, an ultrasound examination was conducted...

Kikuchi-Fujimoto disease (KFD) is rare during pregnancy. It is characterized by necrotizing lymphadenitis and often occurs in young Asian women. We report a case of KFD during pregnancy, which was difficult to diagnose. A 37-year-old pregnant female (gestational week [GW] 7+5 ) was admitted to our hospital because of hyperemesis gravidarum. On the eighth day of hospitalization (GW 8+6 ), she suddenly developed a fever (38.0°C) with skin rash and posterior pharynx redness. Blood tests showed pancytopenia and abnormal liver function...

AIM: The purpose of the study was to compare the ovarian reserve after cystectomy of ovarian endometrioma by bipolar coagulation, suture method, or hemostatic sealants (HSs). METHODS: We performed a meta-analysis of studies in which post-cystectomy serum anti-Müllerian hormone (AMH) values were compared between bipolar coagulation and suture method or between bipolar coagulation and HSs. Through a literature search, we retrieved 14 articles which met inclusion criteria and were eligible for final analysis...

AIM: To investigate the effects of levothyroxine and prednisolone treatment, or in combination, on positive thyroid autoantibodies in infertile patients undergoing in vitro fertilization (IVF) therapy. METHODS: This retrospective study included a total of 190 patients with positive thyroid autoantibodies (anti-T and anti-TPO) who underwent IVF treatment between January 2008 and March 2016. Patients were divided into four groups: group 1-levothyroxine group (n = 50), group 2-prednisolone group (n = 50), group 3-levothyroxine and prednisolone combination (n = 25), group 4-control group (n = 65)...

PURPOSE: To investigate the cost-effectiveness of lenvatinib plus pembrolizumab (LP) compared to chemotherapy as a second-line treatment for advanced endometrial cancer (EC) from the United States and Chinese payers' perspective. METHODS: In this economic evaluation, a partitioned survival model was constructed from the perspective of the United States and Chinese payers. The survival data were derived from the clinical trial (309-KEYNOTE-775), while costs and utility values were sourced from databases and published literature...

BACKGROUND: Ovarian cancer (OVCA) is prevalent in female reproductive organs. Despite recent advances, clinical outcomes remain poor, warranting fresh treatment avenues. Honokiol has an inhibitory effect on proliferation, invasion, and survival of cancer cells in vitro and in vivo. Therefore, this study intended to explore specific molecular mechanism by which honokiol affected OVCA progression. METHODS: Bioinformatics analyzed the drug honokiol that bound to OTU deubiquitinase, ubiquitin aldehyde binding 2 (OTUB2)...

AIM: Methotrexate has demonstrated efficacy in treating ectopic pregnancies. This study explores factors influencing treatment success, focusing on laboratory and ultrasonographic findings, particularly the day 4 to day 1 β-hCG level ratio. METHODS: Retrospective cohort study was conducted within patients diagnosed with tubal ectopic pregnancy. Patients' characteristics, ultrasound findings, laboratory data, and β-hCG levels (days 1, 4, 7), and operation findings were reviewed...

PROBLEM: A comprehensive analysis was conducted to explore the scientific output on immune-related recurrent pregnancy loss (RPL) and its key aspects. Despite the lack of clear explanations for most RPL cases, immune factors were found to play a significant role.

RESULTS: The collected dataset consisted of 2228 articles and reviews, revealing a consistent increase in publications and citations over the past two decades...

AIMS: The underlying mechanism and constitution of spontaneous abortions are complicated and heterogeneous. Many factors, including epigenetic scenarios like micro-ribonucleic acids (miRNAs, MIRs), can additively affect the progression of pregnancy losses. This study aimed to evaluate whether the expression levels of placental inhibitor and/or activator miRNAs had a difference between the numerically abnormal and normal karyotyped spontaneous abortions. METHODS: The case-control study included 100 spontaneous abortion materials consisting of trophoblastic tissues with 42 disomies (controls), 43 aneuploidies (including trisomy 16, 21, 22, and monosomy X), and 15 triploidies...
