Objectives: Public health risks and anxiety have been increasing since the outbreak of Coronavirus disease 19 (COVID-19). The public expresses questions related to the COVID-19 issue through the web base. The aim of this study was to analyze public perception and sentiments of COVID-19 Pandemic in South Korea. Methods: We collected the text data (questions: 252,181) related to COVID-19 from Naver Knowledge-iN during January 1, 2020 to December 31, 2020. The search keywords included related to COVID-19 using Korean words for “SARS-Cov-2”, “COVID19”, “COVID-19”, “Wuhan pneumonia”, “Coronavirus”, “Corona”. A topic modeling analysis was used to investigate and search trends of public perception.The sentiment analysis was conducted to analyze of public emotions in the questions related to COVID-19. We performed the Pearson’s correlation analysis between daily number of COVID-19 cases and daily proportion of negative sentiment in documents related to COVID-19 by COVID-19 outbreak period. Results: A total of 241,776 documents used in this study. The most frequent words in the documents to appear cough, symptoms, tests, confirmed patients, mask and etc.Twenty topics (COVID-test, Economy, School, Hospital/Diagnose, Travel/Overseas, Health, Social issue, Symptom 1 (respiratory), Relationships, Symptom 2 (e.g., fever), Workplace, Mask/Social distancing, infection/Vaccine, Stimulus Package, Family, Delivery Service, Unclassified, Region, Study/Exam, Worry, Anxiety) were extracted using the topic modeling. There was a positive association between the daily counts of COVID-19 patients and proportion of negative sentiment. By COVID-19 period, Stage 4 had the highest correlation. Conclusion This study identified the South Korean public’s interest and emotions about COVID-19 during the prolonged pandemic crisis.

PURPOSE: The aim of this study was to determine the genotype frequencies of interleukin 10 (IL-10) gene polymorphisms and to investigate their association with the risk of respiratory distress syndrome (RDS) in preterm Korean infants. METHODS: Two hundred fourteen preterm infants born at Ewha Womans University Mok Dong Hospital between November 2003 and July 2008 were studied. The cord blood of preterm neonates and the corresponding maternal blood were analyzed by PCR for IL-10 gene (IL-10 -1082A/G, -819T/C, and -592A/C) polymorphisms. The clinical data of patients were collected retrospectively by chart review. RESULTS: The genotype frequencies of IL-10 genes in Korean mothers with preterm infants differ from other reports. The prevalence of two promoter SNPs of the IL-10 cytokine gene was similar but none had the IL-10-1082GG homozygote. Multiple logistic regression analysis demonstrated the risk of RDS to be significantly lower in the infants of the mothers with an IL-10-592AC/CC genotype than in those with an AA genotype (P= 0.033). The risk of RDS was significantly lower in the mother with an IL-10-819TC/CC genotype than in those with a TT genotype (P=0.030). However, IL-10 polymorphisms in the cord blood were not significantly different in preterm infants with RDS compared with the preterm infants without RDS. When we compared the incidence of RDS and each IL-10 A-1082G/T-819C/A-592C haplotype, the ACC haplotype had a protective effect on RDS (P=0.007). CONCLUSION: We conclude that the maternal IL-10-592A/C and IL-10-819T/C polymorphisms may have a role in the development of the RDS in preterm infants.

BACKGROUND: With the development of information and communication technology, there is a growing number of people looking for health information on the internet. This pilot study was performed to analyze the pattern of pharmacist consultation on the internet portal site. METHODS: Questions and answers posted on the portal site “Naver Jisik-iN” from March 1st to 31th in 2016 were collected. Medications asked were categorized into prescription drugs, nonprescription drugs, sanitary aids, emergency drugs, functional health foods, and others. Medications were subcategorized into 14 according to the anatomical therapeutic chemical classification system. Questions were divided into 10 categories based on Hepler's drug-related problems. RESULTS: Of the 955 cases, females accounted for 59.5% and inquirers from 11 to 40 years old, 89.4%. The number of prescription drugs, nonprescription drugs, sanitary aids, emergency drugs, functional health foods, and others were 428 (44.8%), 328 (34.3%), 31 (3.3%), 2 (0.2%), 122 (12.8%), and 44 (4.6%), respectively. Questions for drugs acting on alimentary tract and metabolism took up 27.4% followed by those on nervous system, 13.6% and anti-infectives for systemic use, 12.2%. Pharmacist consultation regarding drug information, drug interaction, and adverse reaction occupied 47.9%, 15.2%, and 12.3%, respectively. CONCLUSION: Health counseling through online is predicted to increase steadily, so pharmacists should broaden their boundaries beyond off-line pharmacies to meet social needs.

Purpose: This study is to develop an interprofessional education (IPE) program for medical, nursing, and pharmacy students and to analyze the effectiveness. Methods: Subjects consisted of 116 students (41 medical, 46 nursing, and 29 pharmacy students) enrolled in their final year. Subjects were randomly assigned to either the intervention group or the control group, with 58 in each group. A pretest-posttest control group design was used. The program was operated for a single day, and consisted of small-group activities and role-play. We utilized the following tools: Perceptions towards Interprofessional Education (PIPE), Self-Efficacy for Interprofessional Experiential Learning (SEIEL), and Perception towards Interprofessional Competency (PIC). We used t-test and analysis of covariance for analysis. Results: The PIPE tool revealed that the scores of the intervention group were significantly higher than those of the control group (p=0.000). The result was the same when the scores were categorized into the groups medical students (p=0.001), nursing students (p=0.000), and pharmacy students (p=0.005). The SEIEL study also indicated the intervention group scored significantly higher than the control group (p=0.000). However, pharmacy students did not reveal significant (p=0.983). The intervention group scored significantly higher than the control group in the PIC. A concluding survey of the intervention group indicated that most students were satisfied with the IPE program. Conclusion We hope this study will provide useful information for designing and improving IPE programs in other universities.

The majority of South Korean females use sanitary pads, which contain various organic solvents which could be excreted before and during their menstruation. However, they are not provided with findings from studies about the health effects of sanitary pads. Therefore, this study aims to establish a list of potential health hazards of sanitary pads and address the need for further extensive research by pointing out the limitations of the previous literature. A systematic review was adopted to conduct quantitative and qualitative reviews based on the PRISMA (preferred reporting items for systematic reviews and meta-analyses). Studies from electronic databases such as PubMed, RISS, and Google Scholar were retrieved for the final analyses. In accordance with our findings, we proposed a set of limitations of the previous studies. A systematic review revealed that there were effects of sanitary pads on vaginal or vulvar skin, endometriosis, and vaginal microflora. The review also revealed that organic solvents, which sanitary pads are composed of, bring potential harmful effects on pregnancy, autoimmune disease, cardiovascular disease, and neurological development. Social environments such as hygiene use or puberty education also turned out to affect female health. It was inferred that a lack of non-occupational and domestic studies reflecting the distinguishing features of sanitary pads with a reliable sample size remains as an important limitation. This study suggests that organic solvents in sanitary pads may increase some health risks bringing reproductive, autoimmune, cardiovascular, and neurological effects. Due to a lack of studies, a more extensive study can contribute to the public health of South Korean females.

Background: Dickkopf-1 (DKK1) regulates bone formation by inhibiting canonical Wnt/β-catenin pathway signaling, and indirectly enhances osteoclastic activity by altering the expression ratio of receptor activator of nuclear factor-κB ligand (RANKL) relative to osteoprotegerin (OPG). However, it is difficult to explain continued bone loss after allogeneic stem cell transplantation (allo-SCT) in terms of changes in only RANKL and OPG. Few studies have evaluated changes in DKK1 after allo-SCT. Methods: We prospectively enrolled 36 patients with hematologic malignancies who were scheduled for allo-SCT treatment. Serum DKK1, OPG, and RANKL levels were measured before (baseline), and at 1, 4, 12, 24, and 48 weeks after allo-SCT treatment. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry before (baseline) and 24 and 48 weeks after allo-SCT treatment. Results: After allo-SCT treatment, the DKK1 level decreased rapidly, returned to baseline during the first 4 weeks, and remained elevated for 48 weeks (P<0.0001 for changes observed over time). The serum RANKL/OPG ratio peaked at 4 weeks and then declined (P<0.001 for changes observed over time). BMD decreased relative to the baseline at all timepoints during the study period, and the lumbar spine in female patients had the largest decline (–11.3%±1.6% relative to the baseline at 48 weeks, P<0.05). Conclusion Serum DKK1 levels rapidly decreased at 1 week and then continued to increase for 48 weeks; bone mass decreased for 48 weeks following engraftment in patients treated with allo-SCT, suggesting that DKK1-mediated inhibition of osteoblast differentiation plays a role in bone loss in patients undergoing allo-SCT.

Purpose: Exposure to heat and cold stress can negatively affect pregnant women. However, studies on the association between ambient temperature exposure and pregnant women, especially those with diabetes mellitus, are limited. The presence of this disease is likely to affect the woman’s capacity to adapt to the demands of pregnancy, consequently affecting fetal development. We examined the association between exposure to the mean temperature and diabetes mellitus during pregnancy. Methods: Health Insurance Reviews and Assessment Service was used to obtain data on patients hospitalized between January 2015 and August 2022. The association between the number of pregnant patients with diabetes mellitus according to monthly mean temperature and seasonal differences was analyzed using a generalized additive model. The model was adjusted for the treatment date, mean humidity, and mean age of the women. Results: The total number of patients with diabetes mellitus in pregnancy was 651,655 and the mean temperature was 12.87℃±9.89℃. The association between the mean temperature and diabetes mellitus during pregnancy showed a U-shaped nonlinear association. During the entire period, the number of patients with diabetes mellitus in pregnancy significantly increased by 2.82 per 1℃ increase in mean temperature (estimate, 2.82; 95% confidence interval [CI], -2.06 to 7.71). The number of patients significantly increased by 72.12 per 1℃ increase in mean temperature in the summer (estimate, 72.12; 95% CI, 50.36–93.89), but the increase was not statistically significant in the winter. Conclusion Our findings suggest that maternal exposure to mean temperature during pregnancy is associated with diabetes mellitus.

In order to solve the problems of traditional teaching model for medical statistics based on theoretical lecture, we developed new teaching model for medical statistics. The model was consisted of theoretical and practical lecture for 2nd grade of premedical students, Ewha Womans University. For theoretical lecture, we introduced basic concepts of medical statistics, data description and social survey method with questionnaire development. For practical lecture, we introduced the whole process from the selection for research topic to sampling, survey, data analysis, and report writing. Although students participated this class pointed out some trivial problems, they gave positive evaluation, particularly on practical lecture. We think this new model will be a good model and let medical students have ability to do medical research through basic knowledge and practical skill.

PURPOSE: This study was performed to obtain baseline information about the occupational and environmental medicine(OEM) residency programs in Korea. METHODS: We surveyed 39 residents for the present training condition, satisfaction, vision of OEM, the condition and satisfaction after residency programs by self- administered questionnaire. RESULTS: Residents want to get appropriate clinical and practical training to be a medical director in a factory or specialist of the occupational medicine based at a hospital. They report, however, that current system for OEM residency training program is not appropriate. The curricula, duration of the each curriculum, level of training hospital or institute need to be reconsidered. CONCLUSIONS: We need to develop more systematic residency program with support from government and OEM society.
