ABSTRACT
OBJECTIVE@#Coronavirus disease 2019 (COVID-19) has spread worldwide, and several virus variants have emerged. Vaccines are administered to help prevent the infection. In Republic of Korea, most people take herbal medicine. This study investigated the use of herbal medicine to counter the side effects of COVID-19 vaccines.@*METHODS@#This cross-sectional study was conducted using an online survey. Chi-square tests were used to determine differences in the use of herbal medication according to sociodemographic characteristics. Independent two-sample and paired t-tests were performed to examine the effect and satisfaction of herbal medicine use for countering the side effects of COVID-19 vaccines. One-way analysis of variance was used to determine vaccine-related differences.@*RESULTS@#A total of 233 and 181 participants received the first and second doses of COVID-19 vaccines, respectively. The majority of herbal medicine users were in their thirties, had a bachelor's degree, suffered from side effects of vaccination, and received Vaxzevria for their first COVID-19 vaccine dose and Comirnaty for their second dose. The herbal medicine group had a higher satisfaction level of post-vaccination side effects than the non-herbal medicine group (P < 0.0001). The numeric rating scale scores for vaccination side effects were lower among participants who took herbal medication to alleviate those symptoms (P < 0.0001). The most commonly used herbal formula was Shuanghetang.@*CONCLUSION@#A third of participants receiving COVID-19 vaccines used herbal medication to counter the side effects of vaccination. The use of herbal medicine was associated with age, education level, vaccine brand, and whether side effects of vaccination occurred. Herbal medication use was associated with greater satisfaction compared to vaccine recipients not using herbal medication. Please cite this article as: Yoon HC.

ABSTRACT
PURPOSE: This study aimed to understand the experiences of married North Korean women's child-rearing, working lives, and their home and work environment in depth.METHODS: This study adopted van Manen's hermeneutic phenomenological method to qualitatively analyze data. The participants were 8 married North Korean women defectors. Data were collected through in-depth interviews and observations from July 4 to August 20, 2018.RESULTS: Nine essential themes emerged: more personal challenges after overcoming a life-threatening crisis; hopes of firmly settling in this land; the wound from the north, which chased them here; a body that becomes stronger through hardship; being stuck in a past full of anxiety and pain; the present is full of hope; hope for the future; sense of alienation from coworkers that cannot be overcome; and sense of power to endure an exhausting work life.CONCLUSION: This study provided a broader understanding of the life and experiences of married women from North Korea. It highlights the need for nurses to recognize their importance in nursing care. The study also suggests that academic and practical approaches for nursing, and basic data for a nursing intervention for married women from North Korea be provided. The study findings can be used as a basis for preparing a national policy that will help North Korean defectors to find employment and gain stability.

BACKGROUND/OBJECTIVES: North Korean refugees (NKRs) in South Korea are a unique population as they must adapt in a new country with similar cultural traits but different social, political, and economic systems, but little research has been conducted on diet and nutrition in this population. This study examined food security, dietary behaviors, and nutrient intakes among adult NKRs living in South Korea and compared them to those of South Koreans.SUBJECTS/METHODS: The subjects were 139 adult NKRs (25 men, 114 women) living in the Seoul metropolitan area, and 417 age- and sex-matched South Korean controls (SKCs; 75 men, 342 women) selected from the Korea National Health and Nutrition Examination Survey (KNHANES). Food security and dietary behaviors (meal skipping, eating-out, meals with family, nutrition education and counseling, and nutrition label knowledge and utilization) were obtained using self-administered questionnaires. Nutrient intakes were assessed by 24-hr recall. The statistical analysis was performed using IBM SPSS ver. 23.0.RESULTS: In South Korea, food security had improved over the previous 12 months, but remained significantly poorer for NKR women than SKC women. Meal skipping was three times more frequent than for SKCs and eating-out was rare. Average energy intake was 1,509 kcal for NKR men and 1,344 kcal for NKR women, which was lower than those of SKCs (2,412 kcal and 1,789 kcal, respectively). Significantly more NKRs (men 24.0%, women 21.9%) showed simultaneously deficient intake in energy, calcium, iron, vitamin A, and riboflavin than SKCs (men 2.7% (P = 0.003), women 7.0% (P < 0.001)). NKR women had a significantly higher index of nutrient quality (INQ) for some nutrients than SK women.CONCLUSIONS: This study reports significant differences in food security, dietary behaviors, and nutrient intakes between NKRs and SKCs. Generally, NKRs reported lower intakes despite improved food security, but relatively good INQs across nutrients. Further research is needed to understand processes of food choice and consumption among NKRs to provide appropriate support aimed at improving diets.
ABSTRACT
PURPOSE: When it comes to cancer care, the psychological well-being of family caregivers has gotten its deserved attention. However, the specific roles that the family caregivers take have not been examined as much. The current study aimed to investigate the distribution of family caregivers' roles, particularly in a family-oriented culture, Korea. MATERIALS AND METHODS: A sample of 439 participants was recruited from 11 national and regional cancer centers in Korea. The participants who were 60 years old or above went through treatments for their gastric, colorectal, or lung cancer. The individual survey included questions regarding the family type, living arrangement, and the sources of support when it comes to their physical, emotional, financial, and decision-making needs. RESULTS: The responses from the participants showed that cancer caregiving is shared by multiple family caregivers; the major source of support for elderly cancer patients on diverse domains was their spouse; patients' reliance on their daughter(s) increased for emotional support; and patients' reliance on their son(s) stood out for financial support and decision-making support. Also, the older the patients were, the heavier their reliance was on the adult children, including sons, daughters, and daughters-in-law. CONCLUSION: Future support programs for elderly cancer patients are suggested to involve multiple family caregivers to encourage effective and efficient intervention. Also, the limitations of the current study and the suggestions for future research are discussed.

PURPOSE: The role of registered nurses is expanding in scope as the healthcare paradigm shifts from acute, hospital-based care to community and population-based care. Given this paradigm shift, this study explores the legal aspects of the role of a registered nurse.METHODS: We used document analysis for extracting laws and legal orders related to nursing from the entirety of Korean law. Using textualism approach, we examined the contents utilizing a framework that was developed based on the role classification of community nurses by Clark in this study.RESULTS: A total of 119 items related to nursing were derived from 64 laws. Of these, 71.4 % can be performed by people in multiple types of occupations including nurses. As a result of analyzing required qualifications, 45.4% of 119 items required additional qualifications besides registered nurse license. Analysis of workplace and activity type demonstrated that 26.1% of the 119 items were related to medical institutions, with nurses performing mostly “Client-oriented role.” More than half (68.9%) were non-medical institutions, with nurses performing mostly “Delivery-oriented role.” Some, however, did not stipulate the nurse's roles clearly.CONCLUSION: Therefore, to match the enhanced scope and responsibilities of registered nurses and to appropriately recognize, guide, and hold these nurses accountable, laws and policy must reflect these changes. In doing so, these updated laws and policies will ultimately serve as a basis for improving the quality and safety of nursing services.

BACKGROUND: The aim of this study was to identify the painkillers preferred for self-administration by doctors working at general hospitals in the capital of the Republic of Korea.METHODS: We collected data, using a questionnaire, from 224 doctors working at secondary or tertiary hospitals in the capital of the Republic of Korea from July 1, 2017 to August 31, 2017. The questionnaire included questions on the preferred type of painkiller for each type of pain and the frequency of painkiller intake. Further, we evaluated the participants on the Likert scale to analyze the consideration and cognition of self-administration of painkillers.RESULTS: The doctors in this study tended to state the trade name of the painkillers rather than the generic name. They preferred acetaminophen for headache and nonsteroidal anti-inflammatory drugs for gastrointestinal (GI) pain, dysmenorrhea, toothache, and musculoskeletal pain. In the choice of painkiller for self-administration, they set utmost importance on the effectiveness of the medicine, followed by the potential side effects, physician's prescription, and the pharmacy's recommendation, in that order. The side effects attribute GI complications, hepatotoxicity, drug tolerance, and delayed diagnosis to painkiller use. There were some remarkable differences between surgeons and non-surgeons, men and women, and specialists and trainees in the conception of painkillers and pain control.CONCLUSION: This is the first study worldwide on the trait of the self-administration of painkillers by doctors, which can serve as a useful reference in clinical settings.

PURPOSE: Seoul and Busan are the two largest cities in Korea. However, life expectancy (LE) in Busan is shorter than in Seoul and among the total Korean population. This study was conducted to decompose age- and cause-specific contributions to the LE difference between Seoul and Busan. MATERIALS AND METHODS: We obtained population and mortality data for Seoul and Busan between 2015 and 2017 from Statistics Korea. We applied Arriaga's decomposition method to life table data to estimate age- and cause-specific contributions to the LE difference between Seoul and Busan. RESULTS: During 2015–2017, LE in Busan was shorter than in Seoul by 2.22 years. Roughly two-thirds of the LE gap between Seoul and Busan was due to excess mortality among elderly people in Busan. The ≥85 age group alone contributed to approximately 20% of the LE gap, while no meaningful contribution was made by the 1–24 age groups. Cardiovascular disease accounted for over 40% of the total LE gap between Seoul and Busan, and this factor was more prominent in women. The top 15 leading specific causes of deaths explained nearly the entire LE difference between Seoul and Busan. CONCLUSION: The difference in LE between Seoul and Busan was due to higher mortality rate in Busan than in Seoul, especially in the elderly population and from cardiovascular diseases. Information on age- and cause-specific contributions to the LE difference between Seoul and Busan may guide health policy-makers to plan strategies for reducing the gap in LE.

Mortalities from cardiovascular disease in Korea have decreased markedly over the past three decades. The major cardiovascular and metabolic risk factors, however, remain prevalent, and their burden on health is large. The Cardiovascular and Metabolic Diseases Etiology Research Center (CMERC) planned a cohort study in order to identify novel risk factors and to develop evidence-based prevention strategies of cardiovascular and metabolic diseases. The CMERC deliberately designed two prospective cohorts, a community-based general population cohort (the CMERC cohort) and its sister cohort (a hospital-based high-risk patient cohort), covering a broad spectrum of cardiovascular and metabolic diseases. This paper describes the CMERC cohort study of community-dwelling adults aged 30 to 64 years. A total of 8097 adults completed baseline measurement between 2013 and 2018. Baseline measurements assessed socio-demographic factors, medical history, health-related behaviors, psychological health, social network and support, anthropometry, body composition, and resting blood pressure and comprised electrocardiography, carotid artery ultrasonography, fasting blood analysis, and urinalysis. Both active follow-up through an annual telephone survey and a 5-year on-site health examination survey and passive follow-up through secondary data linkage with national databases, such as national death records, have been applied. Researchers interested in collaborative research may contact the corresponding author.

PURPOSE: Conditional survival estimates (CSE) can provide additional useful prognostic information on the period of survival after diagnosis, which helps in counseling patients with cancer on their individual prognoses. This study aimed to analyze conditional survival (CS) for hepatocellular carcinoma (HCC) using a Korean national registry. MATERIALS AND METHODS: Patients with HCC, registered in the Korean cancer registry database, were retrospectively reviewed. Overall survival (OS) was calculated using the Kaplan-Meier method. The 1-year CS at X year or month after diagnosis were calculated as CS₁=OS((X+1))/OS((X)). CS calculations were performed in each Barcelona Clinic Liver Cancer stage, after which patients at stage 0, A, and B underwent subgroup analysis using initial treatment methods. RESULTS: A total of 4,063 patients diagnosed with HCC from January 2008 to December 2010, and 2,721 who were diagnosed from January 2011 to December 2012, were separately reviewed. In 2008-2010, the 1-year CS of 1, 2, 3, 4, and 5-year survivors was 82.9%, 85.1%, 88.3%, 88.0%, and 88.6%, respectively. Patients demonstrated an increase in CSE over time in subgroup analysis, especially in the advanced stages. In 2011-2012, the 1-year CS of 6, 12, 18, 24, 30, and 36 months was 81.5%, 83.8%, 85.3%, 85.5%, 86.5%, and 88.8%, respectively. The subgroup analysis showed the same tendency towards increased CSE in the advanced stages. CONCLUSION: Overall, the CS improved with each additional year after diagnosis in both groups. CSE may therefore provide a more accurate prognosis and hopeful message to patients who are surviving with or after treatment.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

PURPOSE: Results from a post-marketing study to generate evidence on 1-year antibody persistence and safety following vaccination of infants from South Korea with the quadrivalent meningococcal conjugate vaccine MenACWY-CRM. MATERIALS AND METHODS: In this phase IV, open-label, multi-center study (NCT02446691), 128 infants received MenACWY-CRM at ages 2, 4, 6, and 12 months. One-year antibody persistence following the full vaccination course was evaluated (primary objective) for the four meningococcal serogroups (Men) by serum bactericidal activity assay using human or rabbit complement (hSBA/rSBA). Immune responses at 1-month post-vaccination and safety were also assessed. RESULTS: The percentage of children with hSBA titers ≥8 ranged between 94% (MenA) and 100% (MenY/W) 1-month post-vaccination, and from 39% (MenA) to 89% (MenY) 1-year post-vaccination. At least 99% and 92% of children had rSBA titers ≥8 and ≥128 against each meningococcal serogroup, 1-month post-vaccination. One-year post-vaccination, the percentage of children with rSBA titers ≥8 and ≥128 ranged from 54% (MenC) to 99% (MenA) and from 30% (MenC) to 98% (MenA). Geometric mean titers declined from 1-month to 1-year post-vaccination, when they varied between 6.8 (MenA) and 53.6 (MenW) by hSBA and between 17.2 (MenC) and 2,269.5 (MenA) by rSBA. At least one solicited and unsolicited adverse event was reported for 79% and 66% of children. Of 36 serious adverse events reported, none were vaccination-related. CONCLUSION: Antibody persistence (hSBA/rSBA titers ≥8) was determined in 39%–99% of children 1 year after a 4-dose MenACWY-CRM series during infancy, with an acceptable clinical safety profile.

BACKGROUND: The objective of this study was to investigate the prevalence, management, and comorbidities of diabetes among Korean adults aged 30 years and older. METHODS: This study used 2013 to 2016 data from the Korea National Health and Nutrition Examination Survey, a nationally-representative survey of the Korean population. Diabetes was defined as fasting glucose ≥126 mg/dL, current use of antidiabetic medication, a previous history of diabetes, or glycosylated hemoglobin (HbA1c) ≥6.5%. RESULTS: In 2016, 14.4% (approximately 5.02 million) of Korean adults had diabetes. The prevalence of impaired fasting glucose was 25.3% (8.71 million). From 2013 to 2016, the awareness, control, and treatment rates for diabetes were 62.6%, 56.7%, and 25.1%, respectively. People with diabetes had the following comorbidities: obesity (50.4%), abdominal obesity (47.8%), hypertension (55.3%), and hypercholesterolemia (34.9%). The 25.1%, 68.4%, and 44.2% of people with diabetes achieved HbA1c <6.5%, blood pressure <140/85 mm Hg, and low density lipoprotein cholesterol <100 mg/dL. Only 8.4% of people with diabetes had good control of all three targets. CONCLUSION: This study confirms that diabetes is as an important public health problem. Efforts should be made to increase awareness, detection, and comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.

Cysticercosis, a parasitic disease caused by Taenia solium metacestode (TsM), has a major global public health impact in terms of disability-adjusted life years. The parasite preferentially infects subcutaneous tissue, but may invade the central nervous system, resulting in neurocysticercosis (NC). NC is an important neglected tropical disease and an emerging disease in industrialized countries due to immigration from endemic areas. The prevalence of taeniasis in Korea declined from 0.3%–12.7% during the 1970s to below 0.02% since the 2000s. A survey conducted from 1993 to 2006 revealed that the percentage of tested samples with high levels of specific anti-TsM antibody declined from 8.3% to 2.2%, suggesting the continuing occurrence of NC in Korea. Modern imaging modalities have substantially improved the diagnostic accuracy of NC, and recent advances in the molecular biochemical characterization of the TsM cyst fluid proteome also significantly strengthened NC serodiagnosis. Two glycoproteins of 150 and 120 kDa that induce strong antibody responses against sera from patients with active-stage NC have been elucidated. The 150 kDa protein showed hydrophobic-ligand binding activities and might be critically involved in the acquisition of host-derived lipid molecules. Fasciclin and endophilin B1, both of which play roles in the homeostatic functions of TsM, showed fairly high antibody responses against calcified NC cases. NC is now controllable and manageable. Further studies should focus on controlling late-onset intractable seizures and serological diagnosis of NC patients infected with few worms. This article briefly overviews diagnostic approaches and discusses current issues relating to NC serodiagnosis.

PURPOSE: The purpose of this study is to understand nursing college life experiences of North Korean Defectors and identify their meanings. METHODS: The study collected data through individual in-depth interviews among six undergraduates or graduates from nursing colleges, using phenomenological research methodology of Colaizzi-one of qualitative research approaches. RESULTS: Six categories drawn as a result of research include ‘Be bumped against hard reality wall’, ‘Bondage of discrimination and prejudice’, ‘Endure and stand with strength of faith’, ‘Myself grown up along with work’, ‘Becoming one amid differences’, and ‘Stepping towards unification’. CONCLUSION: The result of this study would contribute to understanding academic and interpersonal difficulties North Korean defectors might experience at nursing colleges. And it may also help people to learn that they would play an important role in integration of the nursing fields of South and North Korea as well as the nation's unification. Along the way, the results of the study could be basic data to establish national policy helping North Korean defectors adapt to nursing college life, and develop the supporting system of colleges as well as setting up appropriate supports and measures from the perspective of the nursing field.

PURPOSE: This study was done to estimate supply and demand for nursing workforce to provide community-based primary healthcare in the North Korean region to cost-efficiently narrow the health gap between the two Koreas in case of a Korean reunification. METHODS: To understand the nursing education system and current state of nursing workforce in North Korea, the authors interviewed six North Korean defectors who had worked as nurses in North Korea. Based on the interview results and literature review, the supply and demand for the primary healthcare nursing workforce that would be needed after Korean reunification were estimated RESULTS: Currently, a total of 2,100 to 2,700 North Korean nurses were estimated to have graduated from nursing schools with a 2 year curriculum or completed 6-month military nurse training courses every year. The projected number of nurses in demand to provide primary health care ranged from 84,160 to 105,200 and the shortage would be between 31,586 and 52,626. CONCLUSION: An active utilization of the North Korean nursing workforce to improve the health of North Koreans after reunification will be the best way to reduce the reunification cost which will be inflicted mainly on South Korea.

We analyzed Clonorchis sinensis ancient DNA (aDNA) acquired from the specimens of the Joseon mummies. The target regions were cytochrome C oxidase subunit 1 (CO1), internal transcribed spacer 1 (ITS1), nicotinamide adenine dinucleotide hydrogen (NADH) dehydrogenase subunits 2 (NAD2) and 5 (NAD5). The sequences of C. sinensis aDNA was completely or almost identical to modern C. sinensis sequences in GenBank. We also found that ITS1, NAD2 and NAD5 could be good markers for molecular diagnosis between C. sinensis and the other trematode parasite species. The current result could improve our knowledge about genetic history of C. sinensis.

BACKGROUND: This study addressed town-level mortality rates using the National Health Information Database (NHID) of the National Health Insurance Service in Korea in comparison with those derived from the National Administrative Data (NAD) of the Ministry of Interior and Safety. METHODS: We employed the NHID and NAD between 2014 and 2017. We compared the numbers of population and deaths at the national level between these two data sets. We also compared the distribution of the town-level numbers of population and deaths of the two data sets. Correlation analyses were performed to investigate the relation between the NHID and NAD in the town-level numbers of population and deaths, crude mortality rate, and standardized mortality ratio (SMR). RESULTS: The numbers of population and deaths in the NHID were almost identical to those in the NAD, regardless of gender. The distribution of the town-level numbers of population and deaths was also similar between the two data sets during the entire study period. Throughout the study period, the Pearson correlation coefficients between the two databases for the town-level numbers of population and deaths and the crude mortality rate were 0.996 or over. The correlation coefficients for the SMR ranged from 0.937 to 0.972. CONCLUSION: Town-level mortality showed significant correlation and concordance between the NHID and NAD. This result highlights the possibility of producing future analyses of town-level health-related indicators in Korea, including the mortality rate, using the NHID.
