This study aimed to evaluate the current oral health status of Korean children and adolescents and investigate the correlation between fasting plasma glucose levels and oral health in individuals with overweight and obesity. A total of 121,682 participants were selected from the Survey of School Health Examination data provided by the Ministry of Education over the last 5 years to assess recent oral health status and related factors. Among them, 18,105 students with overweight or obesity who had their fasting plasma glucose levels measured were assessed for blood glucose-related analysis. Based on fasting blood glucose levels, the participants were categorized into normal, impaired fasting glucose, and diabetes groups. The associations of these groups with dental caries, oral hygiene, and periodontal diseases were investigated. There were significant associations between demographic factors, health-related behaviors, and blood glucose levels with oral health. Increased fasting blood glucose levels were associated with poor oral health. These results suggest that glycemic management is important in enhancing the oral health of overweight and obese children and adolescents.

Objective: Our aim was to determine if the time interval between bowel resection and initiation of adjuvant chemotherapy impacts survival in advanced ovarian cancers. Methods: This was a retrospective cohort study using data from two cancer centers, Princess Margaret Cancer Centre in Toronto, Ontario, Canada and Samsung Comprehensive Cancer Center in Seoul, South Korea. Patients with International Federation of Gynecology and Obstetrics (FIGO) stage III or IV ovarian cancer that underwent large bowel resection during primary cytoreductive surgery (PCS) were included. Results: Ninety-one women were eligible of which the majority (90.1%) were diagnosed with high-grade serous cancer. The median interval from PCS to chemotherapy for all patients was 21 days (7–86 days). Patients were stratified into 3 groups: 1) Interval ≤14 days, 32 (35.2%) patients; 2) Interval between 15–28 days, 27 (29.6%) patients; and 3) Interval between 29–90 days, 32 (35.2%) patients. Surgical procedures and postoperative outcomes were similar between groups. Multivariate analysis indicated that PCS to chemotherapy interval of 2–4 weeks, younger age, and completion of 4 or more adjuvant chemotherapy cycles were independent prognostic factors of favorable overall survival. Conclusion Initiation of adjuvant chemotherapy between 2 to 4 weeks after PCS with bowel resection may improve survival outcomes in women with advanced ovarian cancer by maximizing the benefit of PCS plus adjuvant chemotherapy.

Background: Whole genome sequencing (WGS) is an increasingly useful tool for tuberculosis (TB) diagnosis and disease management. In this study, we evaluated the utility of userfriendly WGS tools in reporting resistance profiles and identifying lineages of clinical TB isolates from South Korea. Methods: Forty clinical samples from TB patients showing discrepancies between their rapid molecular and conventional drug susceptibility tests were used in this study. Among these clinical isolates, 37 strains were successfully evaluated via WGS software, using the GenTB, TB Profiler, PhyResSE, CASTB, and Mykrobe. Results: More accurate and faster susceptibility results could be obtained with isoniazid than with rifampin. Using the phenotypic test as the gold standard, the isoniazid concordance rate between phenotypic drug susceptibility test (DST) and WGS (GenTB: 45.9%, TB profiler: 40.5%, PhyResSE: 40.5%, CASTB: 48.6%, and Mykrobe: 43.2%) was much higher than between phenotypic DST and rapid molecular genotypic DST (18.9%) among the 37 strains.In contrast, the rifampin concordance rate between phenotypic DST and WGS and that between phenotypic DST and rapid molecular genotypic DST was similar (81.1–89.2%). We also found novel mutations associated with INH in katG and ahpC gene region, not covered by the line probe assay. In addition, lineage analysis identified 81.1% of these samples as L2 East Asian lineage strains, and 18.9% as L4 Euro-American lineage strains. Conclusion WGS may play a pivotal role in TB diagnosis and the detection of drug resistance, genetic diversity, and transmission dynamics in the near future because of its accuracy, speed, and extensibility.

The purpose of this study is to evaluate the antibacterial effects of two liquid fluoride materials on Streptococcus mutans (S. mutans). Riva star aqua™ (SDI, Bayswater, Australia), which consists of silver fluoride (AgF, step 1) and potassium iodide (KI, step 2), and Fluor protector® (FP; Ivoclar Vivadent, Liechtenstein) were used for experimental groups. Experimental groups were divided into 4 groups : AgF, KI, AgF + KI and FP. For the positive control (PC) group, ampicillin was used, and the negative control group (NC) did not receive any additional treatment. Each group was divided into 30 and 50 µL groups by volume of liquid and applied to flat-coated S. mutans. The diameter of the zone of inhibition was measured. The PC and AgF groups showed larger diameters than other materials (p < 0.05), and the AgF group showed no significant difference from the PC group in the 50 µL group (p > 0.05). The FP group showed larger diameters than the AgF + KI group in the 30 µL (p = 0.009). The KI group did not show significant difference from the NC group (p > 0.05). AgF is comparable to ampicillin in antibacterial effects on S. mutans, and better than FP.

Purpose: The purpose of this study was to explore the experience of case management for early psychosis and identify factors influencing care management. Methods: We conducted in-depth interviews with 10 mental health professionals who implemented the Social Treatment for Early Psychosis (STEP) program. The collected data were analyzed using qualitative content analysis. Results: The findings consisted of 4 categories and 15 subcategories. Case management should develop expertise considering the desires of young adults, and grew as experts by promoting family cooperation and coping with mental crises. Administrator's support and peer support programs had a positive impact, while the absence of collaborative systems with psychiatric institution were identified as limitations in the operating system of the basic center. Consulting and monitoring of the metropolitan center provided a foundation for case management at the basic center, while the government's support policy is needed to improve of working environment and set up the youth-friendly early intervention system. Conclusion The results suggest that case management for early psychosis requires multilateral and cooperative efforts by strengthening the capabilities of case managers, establishing an integrated case management network of basic and metropolitan centers, and expanding the government's human and physical infrastructure.

The epithelial barrier in the gastrointestinal (GI) tract is a protective interface that endures constant exposure to the external environment while maintaining its close contact with the local immune system. Growing evidence has suggested that the intercellular crosstalk in the GI tract contributes to maintaining the homeostasis in coordination with the intestinal microbiome as well as the tissue-specific local immune elements. Thus, it is critical to map the complex crosstalks in the intestinal epithelial-microbiome-immune (EMI) axis to identify a pathological trigger in the development of intestinal inflammation, including inflammatory bowel disease. However, deciphering a specific contributor to the onset of pathophysiological cascades has been considerably hindered by the challenges in current in vivo and in vitro models. Here, we introduce various microphysiological engineering models of human immune responses in the EMI axis under the healthy conditions and gut inflammation. As a prospective model, we highlight how the human “gut inflammation-on-a-chip” can reconstitute the pathophysiological immune responses and contribute to understanding the independent role of inflammatory factors in the EMI axis on the initiation of immune responses under barrier dysfunction. We envision that the microengineered immune models can be useful to build a customizable patient's chip for the advance in precision medicine.
