Comparison of the efficacy of vaginal micronised progesterone tablet and gel for fertilisation.

Background: Luteal phase support (LPS) with progesterone is a generally accepted practice after controlled ovarian stimulation, although the best protocols for LPS have been debated. We aimed to compare the efficacy of vaginal micronised progesterone tablets and 8% vaginal progesterone gel for LPS using real-world data.

Methods: This retrospective study included 459 fertilisation/intracytoplasmic sperm injection cycles performed at a university hospital from 2005 to 2019.

Planned Immediate Chemotherapy and Cryopreservation of Oocytes or Embryos for Fertility Preservation in Women with Malignancies.

Oocyte and embryo cryopreservation before gonadotoxic treatment are established methods to increase the likelihood of live births. Although several sociodemographic factors were found to be associated with undergoing fertility preservation (FP) treatment, clinical characteristics such as planned immediate chemotherapy were not fully investigated. We aimed to investigate whether the planned immediate chemotherapy is related to the decision to undergo oocyte/embryo cryopreservation for FP with adjustment for other clinical characteristics.

Clinical characteristics and outcome of lung cancer in patients with fibrosing interstitial lung disease.

Background: Lung cancer (LC) is an important comorbidity of interstitial lung disease (ILD) and has a poor prognosis. The clinical characteristics and outcome of each ILD subtype in LC patients have not been sufficiently investigated. Therefore, this study aimed to evaluate the difference between idiopathic pulmonary fibrosis (IPF) and non-IPF ILD as well as prognostic factors in patients with ILD-LC.

Comparison of resumption of ovulation after cessation of oral contraceptives and medroxyprogesterone acetate in women with polycystic ovary syndrome.

Objective: Both oral contraceptive pills (OCPs) and cyclic medroxyprogesterone acetate (MPA) are widely used to control menstrual abnormalities in women with polycystic ovary syndrome (PCOS). We aimed to evaluate the chance of ovulation resumption after cessation of OCPs and MPA in women with PCOS.

Methods: A retrospective study was conducted of women with PCOS who were treated with OCPs or cyclic MPA from September 2015 to March 2019.

Clinical characteristics and prognostic impact of acute exacerbations in patients with interstitial lung disease and lung cancer: A single-center, retrospective cohort study.

Background: Although acute exacerbation (AE) after treatment for lung cancer (LC) is a poor prognostic factor in patients with interstitial lung disease associated with lung cancer (ILD-LC), the risk of AE according to cancer treatment type remains unclear. Therefore, in the present study, we aimed to investigate the association between AE and treatment received for LC in patients with ILD-LC.

Methods: We conducted a retrospective study of patients with ILD-LC who had undergone treatment for LC between January 2018 and December 2022.

Effect of topical estrogen cream compared with observation in prepubertal girls with labial adhesions.

Background: Topical estrogen treatment has been considered the first-line treatment of labial adhesions in prepubertal girls. However, the effect of topical estrogen cream is different according to studies, and no study compared estrogen cream to observation.

Objective: This study aims to investigate the efficacy of topical estrogen cream treatment compared with observation in prepubertal girls with labial adhesions.

Profiles of perceived resources among low-income, rural mothers: Prospective associations with maternal and child outcomes.

Low-income, rural families face significant mental health risks. However, the understanding of resources associated with mental health risks is limited. The present study investigated the associations between perceived resources of low-income, rural mothers, and longitudinal maternal and child outcomes.

Prediction model of persistent ovulatory dysfunction in Korean women with polycystic ovary syndrome.

Aim: There is no validated tool to predict persistent ovulatory dysfunction after medication with oral contraceptives in women with polycystic ovary syndrome (PCOS), which is the most severe subtype of PCOS. We aimed to build a model to predict persistent ovulatory dysfunction after medication of oral contraceptives in women with PCOS.

Methods: A total of 286 patients with PCOS were treated with and without oral contraceptives at a tertiary academic medical center.

A dynamic systems perspective towards executive function development: Susceptibility at both ends for inhibitory control.

In light of the dynamic systems perspective, the current study expanded existing literature by examining the moderating effect of maternal sensitivity on the quadratic association between infant negative reactivity and future executive function development. Using a longitudinal, multimethod design, we addressed executive function development among preschoolers. This study utilized data from the Family Life Project ( = 1292).

Molecular Mechanism and Prevention Strategy of Chemotherapy- and Radiotherapy-Induced Ovarian Damage.

Fertility preservation is an emerging discipline, which is of substantial clinical value in the care of young patients with cancer. Chemotherapy and radiation may induce ovarian damage in prepubertal girls and young women. Although many studies have explored the mechanisms implicated in ovarian toxicity during cancer treatment, its molecular pathophysiology is not fully understood.

Optimal Oocyte Number in Controlled Ovarian Stimulation with Gonadotropin-Releasing Hormone Agonist/Antagonist and Day 3 Fresh Embryo Transfer.

We aimed to investigate the optimal number of oocytes retrieved in normal responders with the gonadotropin-releasing hormone (GnRH) antagonist (GnRHant) protocol in comparison with the GnRH agonist (GnRHa) long protocol. This retrospective study is based on a single-center cohort including 657 fresh cycles with day 3 embryo transfer using the GnRHa long protocol and the GnRHant flexible protocol at the fertility clinic of a university hospital between 2005 and 2019. The rate ratios (RR) of clinical pregnancy were evaluated using log-binomial regression depending on the categories by the number of retrieved oocytes and pituitary suppression methods.

Predictor for supraphysiologic serum estradiol elevation on hCG triggering day of controlled ovarian stimulation using letrozole and gonadotropins in women with estrogen-dependent cancers.

The objective of this study was to evaluate predicting factors for supraphysiologic serum estradiol elevation during controlled ovarian stimulation (COS) with administration of letrozole and gonadotropins in patients with estrogen-dependent cancer. Use of aromatase inhibitors is recommended to prevent the potential effects of elevated serum estradiol levels and recurrence of tumor in patients with estrogen-dependent cancers during COS. Although previous studies reported that letrozole have shown an effective lowering of peak estrogen levels, a part of patients shows supraphysiologic levels of estrogen associated with ovarian stimulation despite the administration of letrozole.

Short- and long-term outcomes of preterm spontaneous twin anemia-polycythemia sequence.

Background In monochorionic twin pregnancy, placental anastomosis and inter-twin blood transfusion can result in specific complications, such as twin-twin transfusion syndrome (TTTS) and twin anemia-polycythemia sequence (TAPS). It is well established that adverse outcomes are increased in TTTS, but reports on the neonatal and long-term outcomes of TAPS are lacking. The objective of this study was to evaluate the neonatal and neurodevelopmental outcomes in spontaneous TAPS.

Red cell distribution width as a potential prognostic biomarker in fetal growth restriction.

Objective: Red cell distribution width (RDW) is a prognostic marker for adverse outcomes in cardiovascular disease. This association has been attributed to the impaired erythropoiesis and abnormal red blood cell survival originating from chronic hypoxic status or poor nutrition. Considering the pathophysiologic association between fetal growth restriction (FGR) and chronic intrauterine hypoxia, which in turn can result in impaired erythropoiesis, RDW could be a biomarker in FGR.

Le Fort partial colpocleisis as an effective treatment option for advanced apical prolapse in elderly women.

Objective: The aim of this study was to evaluate the outcomes of women with advanced apical prolapse who were treated with the obliterative LeFort partial colpocleisis (LFC) procedure.

Materials And Methods: We reviewed the medical records of patients who underwent LFC for advanced apical prolapse. We collected data for baseline patient characteristics, co-morbidities, severity of prolapse, operating time, intraoperative injuries, and postoperative complications.

Adverse symptoms during short-term use of ulipristal acetate in women with uterine myomas and/or adenomyosis.

Aim: To evaluate various adverse symptoms during short-term use of ulipristal acetate in women with uterine myomas (n = 90), adenomyosis (n = 3) or both (n = 7).

Methods: One hundred premenopausal women who received ulipristal acetate for 4-12 weeks during 2016 to 2017 were selected. The medical records were reviewed and the following information was collected; adverse symptoms during medication, presence of menorrhagia or menstrual cramps, blood hemoglobin and liver function test.

A retrospective analysis of the follicle-stimulating hormone starting dose in expected normal responders undergoing their first fertilization cycle: proposed dose versus empiric dose.

Objective: The purpose of this retrospective study was to evaluate the appropriateness of various follicle-stimulating hormone (FSH) starting doses in expected normal responders based on the nomogram developed by La Marca et al.

Methods: A total of 117 first fertilization cycles performed from 2011 to 2017 were selected. All women were expected normal responders and used a recombinant FSH and flexible gonadotropin-releasing hormone antagonist protocol.

Novel signal peptides improve the secretion of recombinant Staphylococcus aureus Alpha toxin in Escherichia coli.

Secretion of heterologous proteins into Escherichia coli cell culture medium offers significant advantages for downstream processing over production as inclusion bodies; including cost and time savings, and reduction of endotoxin. Signal peptides play an important role in targeting proteins for translocation across the cytoplasmic membrane to the periplasmic space and release into culture medium during the secretion process. Alpha toxin (AT) was selected as an antigen for vaccine development against Staphylococcus aureus infections.

Kaposi's sarcoma-associated herpesvirus microRNA single-nucleotide polymorphisms identified in clinical samples can affect microRNA processing, level of expression, and silencing activity.

Kaposi's sarcoma-associated herpesvirus (KSHV) encodes 12 pre-microRNAs that can produce 25 KSHV mature microRNAs. We previously reported single-nucleotide polymorphisms (SNPs) in KSHV-encoded pre-microRNA and mature microRNA sequences from clinical samples (V. Marshall et al.

Mutational analysis of the latency-associated nuclear antigen DNA-binding domain of Kaposi's sarcoma-associated herpesvirus reveals structural conservation among gammaherpesvirus origin-binding proteins.

The latency-associated nuclear antigen (LANA) of Kaposi's sarcoma-associated herpesvirus functions as an origin-binding protein (OBP) and transcriptional regulator. LANA binds the terminal repeats via the C-terminal DNA-binding domain (DBD) to support latent DNA replication. To date, the structure of LANA has not been solved.

Expression and characterization of a novel enantioselective lipase from Acinetobacter species SY-01.

A novel lipase gene, lipase A, of Acinetobacter species SY-01 (A. species SY-01) was cloned, sequenced, and expressed in Bacillus subtilis 168. The deduced amino acid (aa) sequences for the lipase A and its chaperone, lipase-specific chaperone, were found to encode mature proteins of 339 aa (37.
