Adverse childhood experiences (ACEs) have negative impacts on women with children, including psychosocial and general health problems. However, there is limited research investigating ACEs identifying the characteristics of distinct subgroups according to the frequency of ACEs. Utilizing the national dataset of the Family with Children Life Experience 2017, this study aimed to classify patterns of ACEs based on the total number of types of ACEs and the types of predominant events, and to examine differences in general and psychological characteristics, as well as experiences of violence in adulthood among the classes identified.

Introduction: Cesarean rates are rising, especially for individuals of advanced maternal age (AMA), defined as aged 35 or older. The Robson 10-Group Classification System (TGCS) facilitates assessment and comparison of cesarean rates among individuals in different settings. In midwifery-led care, in which pregnant people are typically healthier and seek a vaginal birth, it is unknown whether individuals of AMA have different antecedents leading to cesarean compared with younger counterparts.

Dysbiosis of the oral microbiota plays an important role in the progression of periodontitis, which is characterized by chronic inflammation and alveolar bone loss, and associated with systemic diseases. Bacterial extracellular vesicles (EVs) contain various bioactive molecules and show diverse effects on host environments depending on the bacterial species. Recently, we reported that EVs derived from Filifactor alocis, a Gram-positive periodontal pathogen, had osteoclastogenic activity.

The differentiation and activity of bone-resorbing osteoclasts are tightly regulated to maintain the homeostasis of healthy bones. In this study, the role of protein tyrosine phosphatase 1B (PTP1B) during osteoclastogenesis was studied in myeloid-specific Ptpn1-deficient (conditional knockout [cKO]) mice. The mRNA and protein expression of PTP1B increased during the formation of mature osteoclasts from mouse bone macrophages on stimulation with macrophage-colony stimulating factor (M-CSF) and receptor activator of nuclear factor κB ligand (RANKL).

Purpose: We evaluated children's cardiometabolic health (CMH) risk indicators and adverse childhood experiences (ACEs) stratified by family structure type (grandparent-headed, two-parent headed, and single-parent headed households). Separately, we assessed whether family structure type and number of ACEs were independently associated with the CMH risk indicators.

Design And Methods: Utilizing data from the 2017-2018 National Survey of Children's Health, we evaluated five CMH risk indicators (obesity, physical activity, secondhand smoke exposure, sleep, and sports participation).

Background: Prostate cancers frequently metastasize to bone, where the best microenvironment for distant colonization is provided. Since osteotropic metastasis of prostate cancer is a critical determinant of patients' survival, searches for preventive measures are ongoing in the field. Therefore, it is important to dissect the mechanisms of each step of bone metastasis, including the epithelial-mesenchymal transition (EMT) and cross-talk between metastatic niches and cancer cells.
