We evaluated the association between sleep duration, dental caries, and periodontitis by using representative nationwide data. We examined 8,356 subjects aged ≥19 years who participated in the sixth Korea National Health and Nutrition Examination Survey (2013~2014). Sleep duration were grouped into ≤5, 6, 7, 8, and ≥9 hours. Presence of dental caries was defined as caries in ≥1 permanent tooth on dental examination. Periodontal status was assessed by using the community periodontal index (CPI), and a CPI code of ≥3 was defined as periodontitis. A chi-square test and multiple logistic regression analysis were used to determine statistical significance. Model 1 was adjusted for age and sex, model 2 for household income, educational level, and marital status plus model 1, and model 3 for smoking status, alcohol consumption, blood pressure level, fasting blood glucose level, total cholesterol level, and body mass index plus model 2. The prevalence of dental caries according to sleep duration showed a U-shaped curve of 33.4%, 29.4%, 28.4%, 29.4%, and 31.8% with ≤5, 6, 7, 8, and ≥9 hours of sleep, respectively. In the fully adjusted model 3, the risk of developing dental caries was significantly higher with ≤5 than with 7 hours of sleep (odds ratio, 1.23; 95% confidence interval, 1.06~1.43). The prevalence of periodontitis according to sleep duration showed a U-shaped curve of 34.4%, 28.6%, 28.1%, 31.3%, and 32.5%, respectively. The risk of periodontitis was significantly higher with ≥9 than with 7 hours of sleep in models 1 and 2, whereas the significant association disappeared in model 3. In a nationally representative sample, sleep duration was significantly associated with dental caries formation and weakly associated with periodontitis. Adequate sleep is required to prevent oral diseases such as dental caries and periodontitis.

Purpose: This study aimed to provide basic data for the future development of school-based sexuality education and school nurse placement policies by examining the sexuality education experience in middle schools according to levels of school nurse placement and identifying factors influencing on adolescent sexual risk behaviors. Methods: This study examined data from the 2018 14th Korean Youth Risk Behavior Survey. The raw data from 30,229 middle school students enrolled in 400 schools were analyzed using descriptive statistics, Chi-square test, independent t test, and complex sample logistic regression analysis. Results: It is found that, in Korea, school nurse placement rates varied by region from 37.9% to 114.8%, resulting in different levels of sexuality and alcohol prevention education (p < .001). Sexuality and alcohol prevention education lowered the likelihood of sexual risk behaviors by 0.54 and 0.87 times, respectively. The experience of drinking alcohol increased a student's likelihood of committing sexual risk behaviors by 4.40 and 3.57 times, respectively, whereas the experience of using a drug increased the risk by 9.42 and 5.00 times, respectively. Personal factors (e.g., gender and academic achievement) and socioenvironmental factors (e.g., school type and perceived economic status) were also found to influence on the sexual risk behaviors of adolescents, although, not to the same degree as sexuality education or health risk behaviors. Conclusion To protect students' sex-related health equity, more elaborate support policies are needed to ensure adequate placement of school nurses able to provide professional sexuality and related health education.

BACKGROUND: This study aimed to evaluate the adhesion of Acanthamoeba trophozoites on cosmetic contact lenses (CLs) with and without CL care multipurpose solution (MPS) treatment. METHODS: Acanthamoeba lugdunensis L3a trophozoites were inoculated onto disks trimmed from CLs: 1-day Acuvue moist, 1-day Acuvue define, Acuvue 2, and Acuvue 2 define. After 18-hour inoculation, the number of adherent trophozoites was counted under phase contrast microscopy. The effects of MPS, Opti-Free Express, soaking CLs for 6 hours, on Acanthamoeba adhesion were analyzed. Scanning electron microscopic examination was performed for assessment of Acanthamoeba attached on the lens surface. RESULTS: Acanthamoeba trophozoites showed greater adhesion to cosmetic CL (P = 0.017 for 1-day CL and P = 0.009 for 2-week CL) although there was no significant difference between the types of cosmetic CL. On all lenses, the number of adherent Acanthamoeba was significantly reduced after treatment with MPS (P < 0.001 for 1-day Acuvue moist, P = 0.046 for 1-day Acuvue define, P < 0.001 for Acuvue 2, and P = 0.015 for Acuvue 2 define), but there was still significant difference between conventional and cosmetic CLs (P = 0.003 for 1-day CL and P < 0.001 for 2-week CL, respectively). More attachment of Acanthamoeba was observed on colored area and the acanthopodia of Acanthamoeba was placed on the rough surface of colored area. CONCLUSION: Acanthamoeba showed a greater affinity for cosmetic CL and mostly attached on colored area. Although MPS that contained myristamidopropyl dimethylamine reduced the adhesion rate, there was a significant difference between conventional and cosmetic CLs.

Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality. Twin pregnancy and cesarean delivery are well-known risk factors for PPH. However, few studies have investigated PPH risk factors in mothers who have undergone cesarean delivery for twin pregnancies. Therefore, this study investigated the risk factors associated with severe PPH after cesarean delivery for twin pregnancies. Methods: We searched and reviewed the Korean Health Insurance Review and Assessment Service’s claims data from July 2008 to June 2021 using the code corresponding to cesarean delivery for twin pregnancy. Severe PPH was defined as hemorrhage requiring red blood cell (RBC) transfusion during the peripartum period. The risk factors associated with severe PPH were identified among the procedure and diagnosis code variables and analyzed using univariate and multivariate logistic regressions. Results: We analyzed 31,074 cesarean deliveries for twin pregnancies, and 4,892 patients who underwent cesarean deliveries for twin pregnancies and received RBC transfusions for severe PPH were included. According to the multivariate analysis, placental disorders (odds ratio, 4.50; 95% confidence interval, 4.09– 4.95; P < 0.001), general anesthesia (2.33, 2.18–2.49; P < 0.001), preeclampsia (2.20, 1.99–2.43; P < 0.001), hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome (2.12, 1.22–3.68; P = 0.008), induction failure (1.37, 1.07–1.76; P = 0.014), and hypertension (1.31, 1.18–1.44; P < 0.001) predicted severe PPH. Conclusions: Placental disorders, hypertensive disorders such as preeclampsia and HELLP syndrome, and induction failure increased the risk of severe PPH after cesarean delivery for twin pregnancy

The purpose of this study was to investigate the association among food intake frequency, nutrient intake, anthropometric measurements, and serum lipids in 100 women and 85 men aged 40-74yrs residing in Jeonju City.

In pre-surgical evaluation of pediatric epilepsy, the combined use of multiple imaging modalities for precise localization of the epileptogenic focus is a worthwhile endeavor. Advanced neuroimaging by high field Magnetic resonance imaging (MRI), diffusion tensor images, and MR spectroscopy have the potential to identify subtle lesions. 18F-FDG positron emission tomography and single photon emission tomography provide visualization of metabolic alterations of the brain in the ictal and interictal states. These techniques may have localizing value for patients which exhibit normal MRI scans. Functional MRI is helpful for non-invasively identifying areas of eloquent cortex. These advances are improving our ability to noninvasively detect epileptogenic foci which have gone undetected in the past and whose accurate localization is crucial for a favorable outcome following surgical resection.

PURPOSE: This study aimed to investigate the relationships among job characteristics, knowledge sharing, organizational culture, and organizational commitment in occupational health nurses (OHN) and clinical nurses (CN) to identify factors that might influence organizational commitment. It aimed to contribute to the improvement of knowledge management in health care organizations, including industrial workplaces and hospitals. METHODS: A convenience sample of 188 nurses, specifically 100 OHN and 88 CN, was selected. Data were analyzed with descriptive statistics, t-tests, correlation coefficients, and multiple regression analysis. RESULTS: OHNs had a significantly higher education level and current work experience; higher proportion of participants with contract employment status, day work shift, less turnover experience, good lifestyle; and higher scores on organizational culture (3.3±0.61) and organizational commitment (3.1±0.60). Additionally, the correlations among organizational commitment, job characteristics, knowledge sharing, and organizational culture ware higher (r=.38~.57) among OHNs as compared to those among CNs. Further, the organizational commitment of OHNs was significantly influenced by knowledge sharing, organizational culture, working hours, and salary (R²=.32), while that of CNs was influenced by organizational culture and life event stress (R²=.11). CONCLUSION: There is a need to develop measures to enable nurses to contribute to the improvement of knowledge management in health care organizations as major human resources, by including interventions for the major factors leading to between-group differences in organizational performance.
