[Associations between Maternal Postpartum Depression and Psychosocial Factors Including Marital Relationship and Social Support].

Objectives: We aimed to investigate the psychosocial factors for postpartum depression as indicated by a high score of the Edinburgh Postnatal Depression Scale (EPDS), including marital relationship and social support. Relevant factors for antenatal depression were also analyzed.

Methods: Thirty-five wife-and-husband pairs who visited University Hospital A for the wife's antenatal health check-up participated in a questionnaire survey using the Japanese version of the EPDS.

A retrospective study of immunotherapy using the cell wall skeleton of Mycobacterium bovis Bacillus Calmette-Guérin (BCG-CWS) for cervical cancer.

Mycobacterium bovis Bacillus Calmette-Guérin (BCG) has the potential to promote adaptive immunity. We sought to examine the synergistic effect of BCG-CWS vaccination on cervical cancer patients undergoing standard treatments including surgery, chemotherapy, and/or radiation. We retrospectively analyzed 103 patients (13 cases administered with BCG-CWS vaccine and 90 controls without BCG-CWS) who underwent a standard treatment for cervical cancer from 2005 to 2021.

Clinical Landscape of PARP Inhibitors in Ovarian Cancer: Molecular Mechanisms and Clues to Overcome Resistance.

The survival of patients with advanced or recurrent ovarian cancer has improved tremendously in the past decade, mainly due to the establishment of maintenance therapy with poly (ADP-ribose) polymerase (PARP) inhibitors (PARPis) after conservative chemotherapies. Despite their superior efficacy, resistance to PARPis has been reported, and patients with resistance have a much worse prognosis. Therefore, the development of novel treatment strategies to overcome PARPi resistance is urgently needed.

Comparison of Aptima and hybrid capture-2 HPV tests and Pap test in the referral population in Japan.

The Aptima human papillomavirus (HPV) test (APTIMA) detects E6-E7 mRNA in abnormal cells in the uterine cervix. To investigate the accuracy of APTIMA for cervical cancer screening in Japan, 423 subjects, mostly referrals with abnormal cytology or being followed up for cervical intraepithelial neoplasia (CIN)1, were screened using two HPV tests, hybrid capture 2 (HC2) and APTIMA, and by the Pap test. Colposcopy was conducted in all subjects with a positive result in either test type.

Single type infection of human papillomavirus as a cause for high-grade cervical intraepithelial neoplasia and invasive cancer in Japan.

To elucidate oncogenic human papilloma virus (HPV) types in Japan, HPV genotyping was performed in 1526 cervical intraepithelial neoplasia (CIN) and 371 invasive cervical cancer (ICC) patients with the novel Genosearch-31+5 HPV test. The HPV-positive rates were 89.3% and 90.

Malignant Transformation of an Ovarian Endometrioma during Endometriosis Treatment: A Case Report.

Dienogest (DNG) is considered to be effective against ovarian endometrioma (OMA). We report a rare case of OMA transformation to ovarian cancer during long-term endometriosis treatment with a periodic administration of a gonadotropin-releasing hormone agonist (Gn-RH agonist) and DNG. The patient was a 41-year-old Japanese woman.

Magnetic Separation of Autophagosomes from Mammalian Cells Using Magnetic-Plasmonic Hybrid Nanobeads.

Developments in subcellular fractionation strategies have provided the means to analyze the protein and lipid composition of organelles by proteomics. Here, we developed ultrasmall magnetic-plasmonic hybrid nanobeads and applied them to the isolation of autophagosomes by applying a magnetic field. The beads were chemically synthesized and comprised an Ag/FeCo/Ag core/shell/shell structure with a mean diameter of 15 nm.

Comparison of the digene hybrid capture 2 and Roche cobas 4800 HPV tests for detection of CIN2+ in a referral population in Japan.

To examine validity of the hybrid capture-2 and cobas 4800 HPV tests, 396 women including 188 women visiting for cancer screening, and 208 referral cases were examined with both HPV tests and the liquid-based cervical Pap test. Concordant results between the HPV assays were observed in 333 cases (coincident rates; 84.1%, kappa value; 0.

Detection of circulating tumor cells in cervical cancer using a conditionally replicative adenovirus targeting telomerase-positive cells.

Circulating tumor cells (CTC) are newly discovered biomarkers of cancers. Although many systems detect CTC, a gold standard has not yet been established. We analyzed CTC in uterine cervical cancer patients using an advanced version of conditionally replicative adenovirus targeting telomerase-positive cells, which was enabled to infect coxsackievirus-adenovirus receptor-negative cells and to reduce false-positive signals in myeloid cells.

Exosomal transfer of functional small RNAs mediates cancer-stroma communication in human endometrium.

Exosomes are small membrane vesicles secreted from a variety of cell types. Recent evidence indicates that human cells communicate with each other by exchanging exosomes. Cancer cells closely interact with neighboring stromal cells, and together they cooperatively promote disease via bidirectional communication.

Concurrent estrogen action was essential for maximal progestin effect in oral contraceptives.

Objective: To investigate the impact of estrogen contained in oral contraceptives (OCs) on the action of progestin on ovarian endometrioma epithelial cells.

Design: Experimental in vitro study and immunohistochemical analysis.

Setting: University hospital.

Molecular characterization of CD133+ cancer stem-like cells in endometrial cancer.

A small subset of cells with CD133 expression is thought to have increased chemoresistance and tumorigenicity, features of cancer stem cells (CSCs); the molecular mechanisms by which these properties arise remain unclear. We characterized CD133+ endometrial cancer cells based on microarray analyses of Ishikawa cells. Of the genes upregulated in CD133+ cells compared with CD133- cells, we noted several key factors involved in the aggressive behavior of cells, including ABCG2 and matrix metalloproteinase (MMP).

Imatinib sensitizes endometrial cancer cells to cisplatin by targeting CD117-positive growth-competent cells.

The use of molecular target therapy has not been established for endometrial cancer. The present study investigated the potential therapeutic strategy of targeting CD117-positive cancer cells as a novel molecular target therapy. FACS-sorted CD117(+) cells isolated from endometrial cancer cell lines (Ishikawa or MFE280 cells) exhibited higher proliferative capacity in vitro and colony forming activity on soft agar, and decreased sensitivity to cisplatin, compared to CD117(-) cells.
