Background: This study aim to compare between middle and high school students on the relationship of high-caffeine drinks and mental health. Methods: This national cross-sectional secondary study used data from the 20th Korea Youth Risk Behavior Survey (2024). The respondents of this study were 54,653 middle and high school students. Descriptive statistics, chi-square analysis, and complex sample logistic regression analysis were performed using IBM SPSS Statistics 25.0. Results: Respondents of ‘much’ perceived stress consumed 1.493 times (P<0.001) more high-caffeine drinks in middle school and 1.699 times (P<0.001) in high school than those of ‘little.’ Respondents of ‘yes’ sadness & despair consumed 1.189 times (P<0.001) more high-caffeine drinks in middle school and consumed 1.142 times (P<0.001) in high school than those of ‘no.’ Suicidal ideation and loneliness variables were statistically significant in middle school, but not in high school. Conclusions It was concluded that middle and high school students who were more stressed and experienced sadness & despair consumed more high-caffeine drinks. However, only middle school students who experienced suicidal ideation and loneliness consumed more high-caffeine drinks. Recognizing each characteristic of middle and high school students, tailored intervention program should be developed based on the community and school.

Objectives: The aim of this study was to provide baseline data for the assessment of exposure to indium and to prevent adverse health effects among workers engaged in the electronics and related industries in Republic of Korea. Methods: Total (n = 369) and respirable (n = 384) indium concentrations were monitored using personal air sampling in workers at the following 19 workplaces: six sputtering target manufacturing companies, four manufacturing companies of panel displays, two companies engaged in cleaning of sputtering components, two companies dedicated to the cleaning of sputtering target, and five indium recycling companies. Results: The level of exposure to total indium ranged from 0.9 to 609.3 μg/m3 for the sputtering target companies; from 0.2 to 2,782.0 μg/m3 for the panel display companies and from 0.5 to 2,089.9 μg/m3 for the indium recycling companies. The level of exposure to respirable indium was in the range of 0.02 to 448.6 μg/m3 for the sputtering target companies; 0.01 to 419.5 μg/m3 for the panel display companies; and 0.5 to 436.3 μg/m3 for the indium recycling companies. The indium recycling companies had the most samples exceeding the exposure standard for indium, followed by sputtering target companies and panel display companies. Conclusions The main finding from this exposure assessment is that many workers who handle indium compounds in the electronics industry are exposed to indium levels that exceed the exposure standards for indium. Hence, it is necessary to continuously monitor the indium exposure of this workforce and take measures to reduce its exposure levels.

In recent da Vinci robot systems (Intuitive Surgical), near-infrared f luorescence imaging (Firef ly technology) has been used. With this technique, it is possible for surgeons to see important structures well beyond the limits of their eyes; hence, surgeons can safely operate and make critical decisions accurately using image-guided surgery. Because parathyroid glands (PTGs) are small and embedded in the surrounding tissues, such as lymph nodes and fat, it is often very hard for surgeons to identify PTGs. To preserve PTGs well, the surgeon must be able to accurately identify PTGs, preserve the vasculature surrounding, and maintain the perfusion to PTGs. Herein, we report an assessment of PTG perfusion using indocyanine green angiography in transoral robotic thyroidectomy.

In the bilateral axillo-breast approach (BABA), the camera is inserted through the areolar incision, and this raises the concern it might be difficult to identify the lymph nodes (LN). The purpose of this study is to evaluate the feasibility of the Firefly for central lymph node dissection (CLND) in robotic thyroidectomy using the BABA. This study evaluated 18 patients who underwent robotic surgery using Firefly between December 2015 and March 2016. For LN mapping, 0.05 ml of ICG was injected into the thyroid 3~4 minutes before CLND. Green-stained LN could be detected easily through a near-infrared camera. The number of retrieved LNs was 7.8±3.0 after CLND using the Firefly, which was higher than the 6.7±0.2 reported in previous surgeries. In addition, it helped to distinguish between the parathyroid and the LNs. The Firefly technology was helpful in identifying the LNs, guiding the CLND and performing a complete CLND.

This study was performed to investigate the changes of oral diet intake during the admission period and identify the factors related with nutritional status in discharging of leukemia patients. This is a retrospective cross sectional study on 46 leukemia patients receiving chemotherapy at the Catholic University of Korea Seoul St. Mary's Hospital from July to September 2009. The patients' charts were surveyed on the general characteristics and factors relating chemotherapy. The calorie count method was used to investigate diet intake during admission period. Multivariate logistic regression analysis was used to identify possible confounding factors. A p < 0.05 was considered statistically significant. The mean age was 42.8 +/- 14.6 years and the average length of stay was 30.4 +/- 7.0 days. The incidence of malnourished patients was 60.9% in discharging. There was a significant difference in chemotherapy sessions and chemotherapy period between well-nourished and malnourished patients. The average energy intake was 1,525.9 kcal in well-nourished patients and 1,143 kcal in malnourished patients, which was significant different. From repeated measures ANOVA test, the changes of oral intake during admission period were significant by groups. In addition, there were significant differences in oral intake according to each period between well-nourished and malnourished patients. In multivariate logistic regression analysis, both the ratio of total oral energy intake to recommended energy intake and chemotherapy sessions were significantly associated with nutritional status in discharging. The results of this study could be used to establish a protocol of nutritional management for leukemia patients receiving chemotherapy.

In June 2022, the first monkeypox case was reported as imported into Korea. The general public asked whether they should get vaccinated against monkeypox because of the recent COVID-19 vaccination experience. As of the current monkeypox outbreak situation, a ring vaccination strategy for the high-risk group is more appropriate than the mass population vaccination with smallpox vaccines. Therefore, identifying the proper target group by available vaccines based on the risk and benefit analysis is a key issue of the vaccination program. In addition, the target group should be reviewed by the epidemiological situation of the jurisdiction along with the updated evidence of the monkeypox virus on transmission dynamics, severity, and fatality.
