  • Purpose: This study aimed to compare the long-term survival rate and peri-implant marginal bone loss between different types of dental implant-abutment connections. Methods: Implants with external or internal abutment connections, which were fitted at Gangneung-Wonju National University Dental Hospital from November 2011 to December 2015 and followed up for >5 years, were retrospectively investigated. Cumulative survival rates were evaluated for >5 years, and peri-implant marginal bone loss was evaluated at 1- and 5-year follow-up examinations after functional loading. Results: The 8-year cumulative survival rates were 93.3% and 90.7% in the external and internal connection types, respectively (P=0.353). The mean values of marginal bone loss were 1.23 mm (external) and 0.72 mm (internal) (P<0.001) after 1 year of loading, and 1.20 mm and 1.00 mm for external and internal abutment connections, respectively (P=0.137) after 5 years. Implant length (longer, P=0.018), smoking status (heavy, P=0.001), and prosthetic type (bridge, P=0.004) were associated with significantly greater marginal bone loss, and the use of screw-cement-retained prosthesis was significantly associated (P=0.027) with less marginal bone loss. Conclusions: There was no significant difference in the cumulative survival rate between implants with external and internal abutment connections. After 1 year of loading, marginal bone loss was greater around the implants with an external abutment connection. However, no significant difference between the external and internal connection groups was found after 5 years. Both types of abutment connections are viable treatment options for the reconstruction of partially edentulous ridges.

  • Objectives: This study was conducted to reflect Korean Medicine doctors (KMD)' perception of lifestyle management in the process of developing a Korean Medicine (KM) Clinical Practice Guidelines (CPG) of female infertility. Methods: We sent four e-mails containing links to online questionnaires to 25,286 KMD belonging to the Association of Korean Medicine. The questionnaire consisted of sexual intercourse, weight, diet, exercise, drinking, smoking, caffeine intake, stress etc. KMD responded to self-administered questionnaires, and we analyzed 786 responds. Results: KMD put stress first among the infertile women's lifestyle management items, weight and sexual intercourse were next. Also KMD put stress first among the spouses' lifestyle management items, drinking and sexual intercourse were next. In relation to sexual intercourse, 'Recognizing the Fertile Window' was the most important. In relation to stress in the emotional domain, 'Depression' and 'Anxiety' were the most important, and in relation to stress in the relationship domain, 'Deteriorating of marital relationship' was the most important. Conclusions: We surveyed the status of KMD' awareness of infertility lifestyle management for patient education, and reflected it in the modification of the CPG for female infertility.

  • Objectives: This study divided the factors that affect participation in health screenings into individual, household, and regional levels and conducted a multi-level analysis to identify the factors related to participation in health screenings. Methods: Participants from the 2017 Community Health Survey were classified into 2 groups (under 40 and 40 or older). A multi-level logistic regression analysis was conducted to identify the factors that affected participation in health screenings. Results: The screening rate of the participants was 69.7%, and it was higher among participants aged 40 and older (80.3%) than it was among participants younger than 40 (49.8%). At the individual level, the factors that influenced participation in health screenings included age, economic activity, smoking status, physician-diagnosed hypertension, and a moderate or high physical activity level. At the household level, the odds ratio of participation in health screenings was high for participants who lived in single-person households, lived with a spouse, earned a high monthly household income, and were not beneficiaries of national basic livelihood security. At the regional level, the odds ratio at the 95% confidence interval level of participation in health screenings was high for participants who had trust in the local community and lived in an area with a proportionally high social welfare budget. Conclusions: This study analyzed nationalwide data and confirmed that individual, household, and regional characteristics affected participation in health screenings. Therefore, policies that prioritize the improvement of regional level factors and especially household level factors are likely to be the most effective for improving the screening rate.

  • Taking vitamin and mineral supplements is increasingly common with the rapid economic growth. The aim of this study was to determine the prevalence of vitamin and mineral supplement use among adults aged 20 or older from the third Korean National Health and Nutrition Survey data and to explore the effect of sociodemographic and lifestyle factors as well as nutrient intake on taking supplements. People who had participated in both a health questionnaire and a nutritional survey were selected, and 2,871 men and 3,555 women were finally included in this analysis. Both men and women with a higher level of education, those residing in a metropolitan area, and those with higher income were more likely to take supplements. Health behaviors were not significantly associated with taking supplements. Mean nutrient intake of all nutrients except energy intake was not significantly different in men or women taking supplements after adjusting for age, education, marital status, resident area, smoking, and energy intake. Compared to Dietary Reference Intake (DRI) for Koreans, most vitamins and minerals, except vitamin $B_2$ and calcium, were consumed at higher than the Recommended Intake (RI) without supplements. In conclusion, taking supplements such as vitamin $B_2$ and calcium may promote health and prevent disease. However, the type and frequency of other vitamin and mineral supplements consumed should be considered with caution.

  • This study aimed to investigate the relationship between the general characteristics of adolescents and their mental health in relation to experiences of heavy drinking. The research utilized raw data from the 18th Youth Health Behavior Online Survey (2022), focusing on 530 participants who reported experiencing heavy drinking in the past 30 days. The study applied weighted composite sample analysis, incorporating frequency, chi-square test, and logistic regression to examine the data. According to the research findings, experiences of heavy drinking showed statistically significant differences across variables such as gender, academic achievement, economic status, sexual experience, and smoking. Additionally, among the mental health characteristics, stress perception, depression, loneliness, suicidal thoughts, suicide planning, and suicide attempts were identified as influencing factors on heavy drinking experiences. These results underscore the need for prevention programs addressing alcohol consumption habits, considering the mental and physical health of adolescents. Developing programs that take into account the relationship between mental health and drinking habits can contribute to forming healthy lifestyle habits during adolescence.

  • Objectives: The objective of this study was to identify factors associated with adolescent obesity, as well as any new factors that correlated with a change in the rate of obesity over time. Methods: The study used 5-yearly data collected by the Korea Youth Risk Behavior Survey starting from the year 2006 up until 2021 (data from 2nd, 7th, 11th, and 17th surveys were analyzed). Factors such as demographics, dietary factors, health behavioral factors, and mental health factors were studied. All data were analyzed using IBM SPSS 27.0, employing chi-square tests and multiple logistic regression analysis. Results: This study included data from a total of 255,200 participants. Factors contributing to obesity varied with time. Over the survey duration of 15 years, low academic achievement, parents with low levels of education, low frequency of fruit consumption, low frequency of fast food intake, long periods of being seated, and high levels of stress were significantly associated with a high rate of obesity. Factors that showed a new correlation with an increase in obesity rates included living with single parents, low frequency of muscle strengthening exercises, and experiencing intense sadness and despair in the past year. Factors that were correlated with a change in obesity rates over time included household economic status, frequency of carbonated beverage consumption, frequency of intense physical activity, and frequency of alcohol consumption. Breakfast intake and smoking were not significantly associated with obesity rates in the 15-year period. Conclusions: While several factors associated with obesity remained consistent over time, several new factors have emerged in response to social, economic, and environmental changes contributed to a change in obesity rate over time. Therefore, to prevent and manage adolescent obesity, continuous research into the new emergent factors contributing to obesity is needed.

  • Objectives: This study compared serum lipid concentration according to drinking habits. Methods: We analyzed data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII). The study included 8,525 adults (3,651 males and 4,874 females), aged 30 - 59 years. Results: There were differences in age, gender, education level, smoking status, physical activity, and waist circumference between drinkers and abstainers. The serum low-density lipoprotein-cholesterol (LDL-C) level of the drinkers was lower than those of the abstainers (P < 0.05). The serum triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) concentrations were highest in the group that consumed alcohol 'more than twice a week' relative to the other groups (P < 0.001). The LDL-C and atherogenic index (AI) levels were lowest in the 'more than twice a week' drinking group compared to the other groups (P < 0.001). The serum TG and HDL-C concentrations were the highest in the '7 glasses/time' group (P < 0.001). The serum LDL-C concentration was the lowest in the '7 glasses/time' group (P < 0.001). Notably, the higher the frequency of binge drinking (7 glasses or more), the higher the concentration of TG (P < 0.001). The serum HDL-C concentration was significantly higher in the 'no binge' and 'more than once a week' groups compared to the other groups (P < 0.001). The serum LDL-C concentration and AI score were the lowest in the 'more than once a week' group (P < 0.001). Conclusions: As the quantity and frequency of drinking increased, the serum TC concentration increased. Moreover, an increase in the serum HDL-C concentration led to a decrease in AI. The factors exacerbating cardiovascular disease increased simultaneously due to drinking. Our results suggest that for individuals with hypertriglyceridemia and patients with low HDL-cholesterolemia, separate guidelines based on the quantity and frequency of alcohol consumption are warranted.

  • BACKGROUND/OBJECTIVES: Few studies have provided evidence of the association between diet quality and dental caries. This study aimed to examine the association between diet quality and untreated dental caries in a Korean representative population. SUBJECTS/METHODS: The study population included a sample of 13,815 participants, aged ≥ 19 from the Korea National Health and Nutrition Examination Survey during 2013-2015. The explanatory variable was diet quality and the outcome variable was untreated dental caries. Untreated dental caries were defined by the number of decayed teeth recorded according to the criteria established by the World Health Organization. Diet quality was defined by using the Korean Healthy Eating Index (KHEI) through the 24-h recall methods. We assessed the association between diet quality and untreated dental caries while adjusting for age, sex, education, income, smoking status, dental visits, toothbrushing frequencies, obesity, and diabetes mellitus. RESULTS: The mean overall KHEI scores in the untreated dental caries group were significantly lower than those in the group without untreated dental caries. Significant differences were observed in the untreated dental caries group based on the KHEI quartiles (P < 0.001). After adjusting for potential confounders, the quartiles of KHEI scores showed an association with untreated dental caries, demonstrating a dose-effect trend (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.35-1.84 for 1st quartile; OR, 1.38; 95% CI, 1.19-1.59 for 2nd quartile; OR, 1.32; 95% CI, 1.14-1.53 for 3rd quartile; reference quartile highest]). CONCLUSIONS: The findings indicated an inverse association between diet quality and untreated dental caries in Korean adults. Healthcare providers should take into account the significant role of diet quality in preventing and managing oral health.

  • Objective: To identify epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma based on 18F-fluorodeoxyglucose (FDG) PET/CT radiomics and clinical features and to distinguish EGFR exon 19 deletion (19 del) and exon 21 L858R missense (21 L858R) mutations using FDG PET/CT radiomics. Materials and Methods: We retrospectively analyzed 179 patients with lung adenocarcinoma. They were randomly assigned to training (n = 125) and testing (n = 54) cohorts in a 7:3 ratio. A total of 2632 radiomics features were extracted from the tumor region of interest from the PET (1316) and CT (1316) images. Six PET/CT radiomics features that remained after the feature selection step were used to calculate the radiomics model score (rad-score). Subsequently, a combined clinical and radiomics model was constructed based on sex, smoking history, tumor diameter, and rad-score. The performance of the combined model in identifying EGFR mutations was assessed using a receiver operating characteristic (ROC) curve. Furthermore, in a subsample of 99 patients, a PET/CT radiomics model for distinguishing 19 del and 21 L858R EGFR mutational subtypes was established, and its performance was evaluated. Results: The area under the ROC curve (AUROC) and accuracy of the combined clinical and PET/CT radiomics models were 0.882 and 81.6%, respectively, in the training cohort and 0.837 and 74.1%, respectively, in the testing cohort. The AUROC and accuracy of the radiomics model for distinguishing between 19 del and 21 L858R EGFR mutational subtypes were 0.708 and 66.7%, respectively, in the training cohort and 0.652 and 56.7%, respectively, in the testing cohort. Conclusion: The combined clinical and PET/CT radiomics model could identify the EGFR mutational status in lung adenocarcinoma with moderate accuracy. However, distinguishing between EGFR 19 del and 21 L858R mutational subtypes was more challenging using PET/CT radiomics.
