INTRODUCTION With the advent of new tobacco products, poly-tobacco use among adolescents is increasing. Smoking among adolescents negatively impacts both their physical and mental health. This study aimed to determine poly-tobacco use among adolescents in South Korea and to identify the mental health problems caused by single-, dual-, and poly-tobacco use. METHODS Data from 54948 adolescents in the 2020 Korea Youth Behavior Web-based Survey were included. Mental health variables of our primary outcome were loneliness, anxiety, and depression. Descriptive statistics, Rao-Scott χ² test and complex sample multivariable logistic regression analysis were conducted to determine the association between the type of tobacco product use and mental health. RESULTS Among the subjects, 95.2% were non-tobacco users, followed by single (3.0%), dual (1.1%), and poly users (0.7%). The subjects with poly-tobacco use had significantly higher rates of loneliness (33.2%, p<0.001), anxiety (22.3%, p<0.001), and depression (49.9%, p<0.001) than those who used fewer tobacco products. Subjects who used poly-tobacco products were 2.13 (95% CI: 1.61-2.83) times more likely to report loneliness, 1.52 (95% CI: 1.12-2.07) times more likely to report anxiety, and 2.18 (95% CI: 1.68-2.82) times more likely to report depression than non-tobacco users. CONCLUSIONS Among adolescents, poly-tobacco use is associated with symptoms of loneliness, depression, and anxiety, which are internalized mental health problems. Poly-tobacco use warrants early assessment of high-risk groups, education on the need for tobacco-use cessation, and active intervention for the psychological difficulties that these high-risk groups experience.

INTRODUCTION Tobacco users are categorized as single, dual, and triple users based on the number of tobacco products (cigarettes, e-cigarettes, and heated tobacco products) used. This study addressed a literature gap by examining how adult Korean tobacco users' quit attempts/plans differed based on the user type, and the associated psychosocial and subjective health-related factors. METHODS We used a questionnaire to examine participants' self-reported health, stress, health concerns, health behavior, tobacco addiction, intentions/plans to quit, and demographic characteristics. Data were analyzed using chi-squared tests, one-way analysis of variance, and multiple linear regression. RESULTS Of the 1288 tobacco users, 55.4%, 28.3%, and 16.4% were single, dual, and triple users, respectively. Self-rated health and stress were lowest among single users and highest among triple users. Most user types had intentions/plans to quit, especially triple users. Quit attempts and plans increased with increasing health behaviors and time elapsed before first tobacco use in the morning, but decreased with higher stress and self-rated addiction. CONCLUSIONS Intentions/plans to quit tobacco use varied based on the type of tobacco user. Multiple users had higher self-rated health, plans to quit, and self-reported addiction; they considered themselves healthy or engaged in healthy behaviors to offset problems from tobacco use and used multiple tobacco products to quit smoking. Highly stressed users had fewer plans to quit and used tobacco for stress relief. Thus, the provision of accurate information about tobacco products and stress management is important to promote successful quitting. [ABSTRACT FROM AUTHOR]

INTRODUCTION Heated tobacco products (HTPs) and nicotine vaping products (NVPs) both are legal consumer products in the Republic of Korea. Little is known about perceptions of harmfulness of HTPs and NVPs relative to cigarettes in South Korea among adults who smoke, and how exposure to marketing may be associated with harmfulness perceptions. METHODS This study used data from the 2020 International Tobacco Control (ITC) Korea Survey, and included 3713 adult (aged 19 years) cigarette smokers who were: 1) exclusive smokers (n=1845); 2) dual HTP + cigarette consumers (n=1130); 3) dual NVP + cigarette consumers (n=224); and 4) triple consumers (all three products, n=514). Weighted multinomial regression models were conducted to estimate smokers' perceptions of harmfulness of HTPs and NVPs compared to cigarettes, NVPs to HTPs, and self-reported exposure to HTP/NVP advertising. Analyses compared the perceptions of harmfulness between the four different consumer groups, and tested whether exposure to HTP/NVP advertising was associated with perceptions of lower relative harm. RESULTS Among all respondents, 27.5% believe that HTPs are less harmful than cigarettes and 23.4% believe that NVPs are less harmful than cigarettes. Exclusive cigarettes smokers were significantly less likely to perceive that HTPs and NVPs are less harmful than cigarettes compared to dual HTP + cigarette consumers, dual NVP + cigarette consumers, and triple consumers (all p<0.001). Half of respondents perceive NVPs as equally harmful as HTPs (14.1% perceive NVPs as more harmful than HTPs). Exposure to HTP/NVP advertising was associated with perceiving these products as less harmful than cigarettes. CONCLUSIONS About one-quarter of Korean cigarette smokers perceive HTPs and NVPs as less harmful than cigarettes. Further investigation is required to understand how harm perceptions and HTP/NVP advertising are related to changes in product use, such as switching between products, using multiple products, or discontinuing all product use.

INTRODUCTION This study examined the association between smoking status and death from COVID-19. METHODS This study used nationwide cohort data collected from the Korean National Health Insurance Service, linking to information on all individuals who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The smoking status of subjects who participated twice in national health screenings between 2015 and 2018 was measured. This study investigated death from COVID-19 among those who tested positive from 1 January to 30 May 2020. RESULTS This study included 4259 patients who tested positive for SARS-CoV-2 in Korea. After adjusting for all potential confounding factors, current smokers (adjusted odds ratio, AOR=3.75; 95% CI: 1.23-11.36) and recent quitters (AOR=3.74; 95% CI: 1.12-12.53) were associated with an increased risk of death from COVID-19 compared to never smokers. Compared with current smokers, long-term quitters (AOR=0.33; 95% CI: 0.11-0.95) and never smokers (AOR=0.27; 95% CI: 0.09-0.81) were associated with a reduced risk of death from COVID-19. CONCLUSIONS Smoking was associated with an increased risk of death among patients with COVID-19. Given the lower possibility of death in long-term quitters with COVID-19, continuous smoking cessation among smokers or recent quitters is needed. [ABSTRACT FROM AUTHOR]

introduction Occupational health nurses (OHNs) in South Korea who visit the workplace periodically could play a key role in smoking cessation. It would be helpful to assess their understanding of smoking hazards and smoking cessation methods to encourage them to provide smoking intervention services at the workplace. This study aimed to investigate the knowledge of smoking hazards and perceptions of smoking cessation methods among OHNs. methods We conducted an anonymous self-administered cross-sectional questionnaire survey of 108 OHN nurses employed in an occupational health service outsourcing specialized agency with 19 regional branches in Korea from July to August 2019. We assessed the perceptions of the OHNs about smoking interventions, hazards of smoking, and perceived competence to counsel smokers according to training experience, using chi-squared tests and Fisher's exact tests. results The majority of the nurses underestimated the smoking-attributable fraction for lung cancer (78.7%), chronic obstructive pulmonary disease (64.8%), and mortality (49.0%), regardless of training experience on smoking cessation, while more than half perceived their skill and knowledge to counsel patients concerning smoking as inadequate (56.5%). However, those trained in smoking cessation interventions felt more competent in smoking cessation counselling, with 52.2% and 29.3% in the trained and non-trained groups, respectively (p=0.019). conclusions The OHNs in this study underestimated smoking hazards and perceived themselves as lacking counselling skills regarding smoking cessation interventions. It is necessary to encourage OHNs to promote smoking cessation by increasing their knowledge, skills and competence in smoking cessation interventions. [ABSTRACT FROM AUTHOR]

Background The rising incidence of thyroid cancer (TC) has generated growing concern globally; yet there are no studies examining whether this incidence was followed by a rise in related mortality. We aimed to comprehensively quantify current trends and future projections of TC incidence and mortality, and to explore the association between the TC burden and socioeconomic inequality in different income strata. Methods We obtained incidence and mortality data on TC and population from the 2019 Global Burden of Disease (GBD) study and the United Nations' World Population Prospects 2022. We applied an age-period-cohort (APC) model to estimate the overall annual percentage change (net drift) and age, period, and cohort effects from 1990 to 2019, and also constructed a Bayesian APC model to predict the TC burden through 2030. Results Over a third of global TC cases belonged to the high-income group. From 1990 to 2019, net drifts of TC incidence were >0 in all income groups, while a modest reduction (net drift <0) in mortality was observed in most income groups, except for the lower-middle-income group. Unfavourable age, period, and cohort effects were most notable in Vietnam, China, and Korea. The age-standardised incidence rate (ASIR) is predicted to increase whereas the age-standardized mortality rate (ASMR) is expected to decrease globally between 2020 and 2030, with geographic heterogeneity being detected across income groups. We observed a positive correlation between ASIR and universal health coverage index and health worker density, but a negative one between ASMR and the two indicators, primarily in upper-middle-income and high-income countries. Conclusions Opposite patterns in incidence and mortality of TC raise concerns about overdiagnosis, particularly in upper-middle-income and high-income countries. Discrepancies in the distribution of health service accessibility, including diagnostic techniques and therapeutic care, should be addressed by narrowing health inequalities in the TC burden across countries.

Aims: Global business today usually requires organizations to be present locally in countries where their customers are. To do this successfully, good cooperation with local people is needed. Therefore, this paper focuses on the integration of cultures in the business world. The insights from this study are expected to benefit Slovenian expatriates to foreign companies in South Korea, as well as national culture researchers. The main goals of this research include a comparison of Hofstede's IBM survey results with the researched working environment, and identifying the benefits of merging two national cultures for the working environment. Methods: A questionnaire was distributed to purposive samples within the researched working environments and the collected data analysed used SPSS, where the hypotheses were tested using a chi-square test and t-test for independent samples. Results: The results revealed significant differences between the two national cultures in the working environment, e.g.: fear of expressing disagreement towards superiors, commitment to work, preference of challenges, tendency to avoid conflicts and innovations -- all differed according to nationality. Conclusion: Working together with people from different cultures requires a certain amount of adaptation (learning about another culture, expecting situations that are not usual). If this adaptation is successful, then cooperation between the different cultures can also be successful, leading to a potential output that is even better than cooperation between people from the same culture.

Background/objectives: Sarcopenia, characterized by the progressive loss of muscle mass and strength, poses significant risks to physical health, leading to a reduced quality of life (QoL), increased disability, and higher mortality rates among older adults. Early detection and intervention are crucial to prevent the cascading effects of sarcopenia, including falls, fractures, and hospitalization. This study determined an optimal cut-off point of the SarQoL® score that can serve as an effective screening tool among community-dwelling Korean older adults. Methods: The study involved 451 South Korean older adults, assessing the correlation between SarQoL® scores and sarcopenia as defined by the Asian Working Group for Sarcopenia (AWGS) criteria. Participants completed the Korean version of the SarQoL questionnaire. Results: Findings revealed that individuals diagnosed with sarcopenia had significantly lower SarQoL® scores compared to non-sarcopenic participants, with a cut-off score of ≤58.5 providing good diagnostic accuracy (AUC = 0.768, sensitivity = 69.3%, specificity = 75.2%). Conclusions: These results underscore the questionnaire's reliability and validity in screening for sarcopenia-related QoL impairment and its potential utility as a clinical tool. Implementing the SarQoL® in routine assessments could improve clinical outcomes by enabling earlier and more precise identification of sarcopenia. [ABSTRACT FROM AUTHOR]

This study utilized nationally approved data from the 2022 Long-Term Care Survey of Korea to examine the factors associated with career disruptions and employment status among family caregivers of home-based care recipients. Descriptive statistics, chi-square tests, one-way ANOVA, and multinomial logistic regression analysis were employed to address the research questions. The results indicated that 19.39% of family caregivers of home-based care recipients experienced career disruptions due to informal caregiving. Demographic factors such as gender, age of family caregivers, and their relationship with care recipients predicted their employment status. Gender was a significant explanatory factor, as daughters/daughters-in-law were more likely to be in insecure employment positions than sons. Lower household income and older age were also associated with employment insecurity. Recommendations include coverage expansion, family support programs, and pension credit for family caregivers to meet the needs of care recipients and their families. [ABSTRACT FROM AUTHOR]

This study explored the relationship between depressive symptoms and suicidality among community-dwelling adolescents aged 10–18 years, examining whether self-esteem, somatic symptoms, and self-harm mediate this relationship. Utilizing a pre-existing dataset from a nationwide adolescent mental health survey conducted in Korea in 2021, data were collected using several standardized self-administered instruments: the Korean version of Rosenberg's self-esteem scale, Korean Children's Somatization Inventory, Korean version of the Self-Harm Inventory, Mental Health Screening for Depressive Disorders, and Mental Health Screening for Suicide Risk. A path model was constructed and validated, followed by path analysis to assess the effects. Data from 6689 adolescents, including 5937 students and 752 out-of-school adolescents, revealed that 18.7% were in the suicidality group, 11.8% experienced depressive symptoms, 57.9% exhibited somatic symptoms, and 27.4% engaged in self-harm. Depressive symptoms had a positive direct effect on suicidality (β = 0.166, p < 0.001, 95% confidence interval = 0.159–0.172). Bootstrapping tests showed a statistically significant indirect effect of self-esteem, somatic symptoms, and self-harm on the relationship between depressive symptoms and suicidality (β = 0.021, 95% confidence interval = 0.013–0.029). Our findings suggest that self-esteem, somatic symptoms, and self-harm mediate the relationship between depressive symptoms and suicidality, and comprehensive mental health management strategies addressing these factors are recommended.

This study aimed to determine the effects of virtual reality (VR)-based meditation on the sleep quality, stress, and autonomic nervous system balance of nursing students. Nursing students were categorized into experimental groups I (VR-based meditation) and II (concentration meditation) and a control group. Before the study's initiation, we measured the participants' general characteristics, and a sleep measurement device was used to measure sleep quality. Stress levels and heart rate variability were measured before and after study completion. On the first day, all three groups slept without any intervention. On days 2–6, only experimental groups I and II implemented the intervention before sleeping. We found that the subjective sleep quality, wakefulness after sleep onset, sleep efficiency, deep sleep quality, subjective stress, objective stress, and autonomic nervous system balance of the VR meditation group were significantly better than those of the other groups. Our results reveal that the participants who underwent VR-based meditation experienced better sleep quality, lower stress levels, and improved autonomic nervous system balance compared with those in the concentration meditation and control groups. Thus, VR-based meditation effectively enhances sleep quality, lowers stress levels, and improves autonomic nervous system balance in nursing students. [ABSTRACT FROM AUTHOR]

Objectives: This study investigated the impact of structural isolation within peer relationships on physical activity levels among Korean adolescents, exploring how different types of social isolation within classroom networks influence physical activity. Methods: This study utilized cross-sectional survey data. Specifically, using data from the 8th Korean Children and Youth Happiness Index survey (2016), which included 3356 middle and high school students in Korea, the study employed binary logistic regression and social network analysis to assess the relationship between social isolation and physical activity. Based on types of isolation, adolescents were categorized into social avoidant, actively isolated and socially indifferent groups. Results: The analysis demonstrated significant differences in physical activity based on social isolation status (χ2 = 13.0, p < 0.001) and types of social isolation (χ2 = 18.3, p < 0.001). Key variables such as gender, household subjective economic status, and self-rated health significantly influenced physical activity. The number of physically active friends had a considerable impact on both non-isolated groups (OR = 1.31, p < 0.001) and the actively isolated group (OR = 1.42, p < 0.05). The actively isolated group exhibited the highest explanatory power in the logistic regression models (Nagelkerke R² = 0.230). Conclusions: This study has highlighted that not only social isolation but also the type of isolation significantly influences physical activity among adolescents. Understanding these distinctions and tailoring interventions accordingly are crucial for promoting physical activity among socially isolated adolescents. [ABSTRACT FROM AUTHOR]

Background: We evaluated changes in the smartphone use rate and time among Korean adolescents and their awareness of associated health problems. Methods: This study was a secondary analysis of the Korea Youth Risk Behavior Survey (2020–2023) conducted by the Korean Disease Control and Prevention Agency. The total number of enrolled adolescents aged 12–18 years was 214,526. Results: The weekly smartphone usage rate increased from 96.4% to 97.1% (p = 0.03), with no significant changes observed in weekend usage. The average smartphone use time was 4.7 h on weekdays (p = 0.17) and 6.6 h on weekends (p = 0.37). Middle school adolescents had a higher weekday use rate than high school adolescents, but the average smartphone use time was significantly less. By 2023, the proportion of adolescents with overdependence was 28% (n = 14,672). Additionally, 11.8% (n = 6255) responded that they had experienced health problems due to smartphone use. Conclusions: The longer they used their smartphones for on the weekends, the more likely they considered their health to be worse. In conclusion, our youth population needs to be educated on the proper use of smartphones. [ABSTRACT FROM AUTHOR]

Cognitive frailty, which is characterized by the co-occurrence of physical frailty and cognitive impairment, poses significant risks to the well-being and independence of elderly individuals. Previous research has established that demographic, health-related, and social factors contribute to both physical frailty and cognitive decline. However, the role of social factors in influencing cognitive frailty remains unclear. This study aims to identify the relationship between social factors and cognitive frailty among Korean older adults living in the community. We performed secondary analyses of data from the 2020 Survey on Older Adults. After entering demographic factors and health-related factors into the logistic model as covariates, this study explored the association between cognitive frailty and social factors, including living arrangements, social support, the frequency of engagement in social activities per week, and satisfaction with friends and community. Among participants, approximately 2.9% had cognitive frailty, 3.2% had only physical frailty, and 21.9% had only cognitive decline. Lower levels of satisfaction with friends and the community and infrequent participation in social activities were strongly correlated with cognitive frailty. These findings emphasize the necessity of public health programs that encourage older individuals' social involvement. A supportive social environment can be fostered through initiatives that promote community events, group activities, and volunteerism. Public health policies should prioritize the development and maintenance of social activity centers that offer various programs to prevent progression to cognitive frailty in older adults.

A virtual-reality-simulation-based nursing education program incorporating an information processing model helps nursing students develop their learned knowledge as nursing behavior and develop their ability to cope with complex clinical challenges. The purpose of this study is to develop a nursing education program using an immersive virtual reality simulation app for clinical situations based on an information processing model and identify the effects. A non-quantitative control group pretest–post-test design was employed. The programs were developed using the ADDIE model and an information processing model. In order to verify the effectiveness of the program, six adult nursing learning issues were taught to the experimental group over 6 weeks. The nursing education program in this study provides comprehensive experiential learning through advanced virtual simulation, significantly enhancing nursing students' performance confidence, critical-thinking abilities, and problem-solving skills across a wide range of clinical scenarios. By repeatedly engaging with diverse learning topics related to adult nursing, this program not only equips students with essential practical skills but also contributes to the overall improvement of patient safety and the quality of medical care.

Aims. This study aimed to analyze the effects of the surgery preparation time on patient outcomes. Background. Postoperative complications have a decisive effect on postoperative survival. The anesthesia time is a crucial determinant of such complications. Competent operating room nurses can shorten the surgery preparation time, which is the time from when anesthesia is first administered to the making of the surgical incision. The shortening of this preparation time can shorten the anesthesia time and may reduce postoperative complications. However, discussion of this preparation time is insufficient. Therefore, this study analyzed the effect of the surgery preparation time on patient outcomes. Methods. From electronic health records data, this retrospective cohort study used the data of 1,944 patients who had been immediately admitted to the ICU after their surgery between 2017 and 2020. The patients were divided into two groups: ≥30 minutes preparation time and <30 minutes preparation time groups. We performed chi-squared tests and t-tests to determine differences in preoperation, intraoperation, and postoperation characteristics of the patients and patient outcomes based on the surgery preparation time. Furthermore, we performed a multiple logistic regression by including 12 adjusted variables to determine the influence of the surgery preparation time on patient outcomes. Results. Among the 1,944 patients, 820 were in the ≥30 minutes preparation time group and 1,124 in the <30 minutes preparation time group. The multiple logistic regression analysis showed that the surgery preparation time affects alertness (OR = 1.44; 95% CI: [1.09, 1.90]), ventilator application (OR = 1.32; 95% CI: [1.03, 1.70]), and length of stay in the ICU (OR = 1.69; 95% CI [1.16, 2.47]). Conclusions. The surgery preparation time affects postoperative patient outcomes. The competence of operating room nurses is the most essential aspect of the surgery preparation time. Implications for Nursing Management. It is important to analyze operating room nurses' tasks, standardize the tasks, and educate nurses according to their experience level to reduce the surgery preparation time and improve patient outcomes.

Background: Since 1999, reimbursements for nursing services for inpatients have been paid differentially according to the nurse staffing ratios in Korea. However, differentiated nursing fees are insufficient for nurse staffing; thus, steps have been taken to improve the policy. This study aimed to identify the impact of a policy that changed the method of calculating nurse staffing ratios from the nurse-to-bed ratio to the nurse-to-patient ratio on improving the nurse staffing ratio in medical institutions. Methods: Data were collected from 1,339 medical institutions that continuously provided medical services from 2017 to of 2021, and a prospective cohort was used for analysis. A generalized estimating equation for longitudinal ordered logistic regression was used to identify the impact of this policy change on the nurse staffing ratios in medical institutions. Results: During the cohort study, 59.8% of the first-applied group of medical institutions and 65.6% of the second-applied group of medical institutions improved their nurse staffing ratios. However, only 22.6% of the medical institutions to which the revised calculation method was not applied improved their nurse staffing ratios. A statistically significant difference was found in the improved nurse staffing ratio depending on whether and when the revised calculation method was applied (χ2 = 89.830, p <.001). The analysis of nurse staffing ratios of medical institutions from 2017 to 2021 showed that the likelihood of improving the nurse staffing ratio increased gradually after the revised calculation method was adopted. Also,the likelihood of the nurse staffing ratio improving in the first-applied group was 1.41 times higher (odds ratio = 1.41, 95% confidence interval = 1.04–1.92) than in the non-applied group. The odds ratio for the improvement of nurse staffing ratio in the second-applied group was 2.35 (95% confidence interval = 1.76–3.14). Conclusions: Financial incentives inherent in the new policy can be regarded as the driving force behind improvements in nurse staffing ratios. The revised calculation method should be extended to all medical institutions nationwide, and the law should be revised to secure the minimum number of nurses. [ABSTRACT FROM AUTHOR]

Mobilization with movement (MWM) and myofascial release (MFR) are treatment techniques that increase ankle dorsiflexion range of motion (DFROM). Manual lymphatic drainage (MLD) facilitates waste drainage and improves soft tissue tension in peripheral tissues. To date, no studies have investigated how the combination of MLD, MWM, and MFR influences the human body. The purpose of this study is to determine how the combination of MLD, MWM, and MFR affects DFROM and balance ability. We randomly assigned 16 individuals (26 feet) to one of three groups: MWM-MFR (MR), MWM-MLD (MD), or MWM-MFR-MLD (MRD) intervention. To confirm the intervention effect of each group, DFROM was assessed using a modified lunge test, and dynamic balance was measured using a modified star excursion balance test. In the results, differences were found between the MR and MRD groups in PL and mGCM activities in the 1 section (p = 0.008, p = 0.036) and between the MD and MRD groups in mGCM activity in the 4 and 5 sections (p = 0.049, p = 0.004). We suggest that the application of MRD is the most effective intervention for increasing muscle activation of the PL and mGCM during the modified star excursion balance test. [ABSTRACT FROM AUTHOR]

Individuals with intellectual disabilities have a shorter lifespan and significantly higher prevalence of conditions such as hypertension and cardiovascular diseases than healthy individuals. Thus, assessing the elements that contribute to their physical fitness is crucial. This cross-sectional study examined the relationship between the blood pressure and physical fitness of people with intellectual disabilities in South Korea, considering differences across sexes, age groups, physical attributes, and disability levels. It used data from 8502 individuals with intellectual disabilities aged 20–59 years who participated in a survey of a National Fitness Standard Center (NFSC) between 2018 and 2021. A series of t-tests, one-way analysis of variance, logistic regression, and the four-quartile method were used for data analyses. The results showed differences in physical fitness levels between men and women considering all aspects except for BMI (Body Mass Index), with men showing higher blood pressure levels. Lower grip strength, lower PEI (physical efficiency index) scores, and higher BMI were associated with increased blood pressure. Additionally, individuals with higher levels of disability tended to have lower levels of physical fitness, while higher physical fitness levels were associated with lower blood pressure. Therefore, low fitness levels and hypertension risk may be important health indicators for people with intellectual disabilities. [ABSTRACT FROM AUTHOR]

Context: Gratitude intervention is expectedly an effective intervention to reduce depression and improve the quality of life in schizophrenic patients, but there is a lack of literature on it. Aims: We attempted to develop and test the effectiveness of the gratitude disposition promotion program for chronic schizophrenic patients in Korea. Settings and Design: Nonequivalent control group pre- and post-test design was used in two mental health centers located at Gyeonggi-do in South Korea. Materials and Methods: This paper was a quasi-experimental study and the participants who took part in the gratitude disposition promotion program were 17 of experimental group and 15 of control group. Gratitude disposition (the short gratitude, resentment, and appreciation test), depression (Beck Depression Inventory), and quality of life (developed by Kook) of chronic schizophrenic patients were measured before and after an intervention, as compared to the control. Statistical Analysis: Chi-square test, Fisher's exact test, and t-test were performed for prehomogeneity testing for variables related to the general characteristics. Testing for the effectiveness of gratitude disposition promotion program and hypothesis testing for its effect on depression and quality of life were by ANCOVA and t-test, as verified to significance level of P < 0.05. Results: The participants who received the gratitude disposition promotion program showed significant improvements in gratitude disposition (F = 18.740, P < 0.0001) and in quality of life (F = 9.800, P = 0.004), but no significant difference in depression (F = 3.870, P = 0.059). Conclusions: The gratitude disposition promotion program was an effective clinical intervention program for enhancing gratitude disposition and quality of life of chronic schizophrenic patients in community.

Introduction: Since 2019, the Korean government has implemented a pilot project for integrated care to encourage healthy aging of older adults. This study investigated the changes in hospitalization rates among older adults who participated in the integrated care pilot project. Methods: Administrative survey data collected from 13 local governments and the National Health Insurance Database were used in present study. The participants comprised 17,801 older adults who participated in the pilot project between August 01, 2019 and April 30, 2022 and 68,145 matched controls. A propensity score matching method was employed to select the control group, and this study employed difference-in-differences (DID) approach to examine variations in the hospitalization rate. Results: The DID analysis revealed that the odds ratio for rates of hospitalization among older adults who participated in the pilot project was 0.88 (95% confidence interval [CI] 0.84, 0.91) in comparison to control group. In specifically, as compared to the control group, the odds ratio for hospitalization rates among the pilot project's discharged patients was 0.17 (95% CI 0.15, 0.20). Although not statistically significant, the odds ratio of older adults who utilized LTCI services was 0.93 (95% CI 0.83, 1.05), and the odds ratio of older adults who applied for LTCI but were rejected or were intensive social care was 1.09 (95% CI 0.95, 1.26) compared to the comparison group. Discussion: The findings imply that the discharged patient group had greater medical demands than the other types, and it can be claimed that this is the group that may anticipate greater efficacy while using health services. In addition, the integrated care services provided by the pilot project have the effect of reducing unnecessary hospitalization such as social hospitalization. Conclusion: Participants in the integrated care pilot project showed a lower hospitalization rate than the older adults who did not participate in the project but had similar characteristics. In particular, the admission rate of discharged patients showed a sharp decline. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to examine the health concerns of parents regarding their premature infants and to identify changes in these concerns during perinatal period and after discharge. Methods: This was a retrospective study performed at a single tertiary center that enrolled 119 premature infants who were discharged from the neonatal intensive care unit (NICU) and visited the outpatient pediatrics department between December 2018 and October 2021. Data on the concerns of 176 parents regarding enrolled premature infants' health from before birth to 1 week after NICU discharge were obtained from outpatient records. The t test and with the chi-squared test were used to analyze the data for this study. Results: The consistently greatest focus of parents' health concerns was the respiratory system. The second focus of parents' health concerns before discharge was the central nervous system. However, during the first week after NICU discharge, the gastrointestinal system was the second-most frequent focus of parents' health concerns among parents of infants without diseases related to prematurity and infants with older gestational ages. Conclusion: The results of this study offer insights into the health concerns among parents of premature infants. Parental health concerns about premature infants vary over time, from before birth to post-discharge, necessitating supportive interventions to enhance parental understanding of their child's health status.

Purpose: This study investigated the relationship between allergic diseases, general anxiety disorder, and depressive symptoms among Korean adolescents. Methods: A secondary analysis was conducted on the findings of the 18th Korea Youth Risk Behavior Survey (2022). The study included 51,850 adolescents and analyzed the relationships among allergic diseases, general anxiety disorder, and depressive symptoms using complex samples logistic regression analysis. Results: Among the Korean adolescents, 12.7% experienced general anxiety disorder, while 28.7% experienced depressive symptoms. The prevalence of allergic diseases was 5.7% for asthma, 36.3% for allergic rhinitis, and 22.2% for atopic dermatitis. General anxiety disorder was associated with asthma and allergic rhinitis but not atopic dermatitis. Depressive symptoms were associated asthma, allergic rhinitis, and atopic dermatitis. Conclusion: Examining the correlation among allergic diseases, general anxiety disorder, and depressive symptoms in adolescents underscores the need for implementing suitable strategies. Moreover, when addressing general anxiety disorder and depressive symptoms in adolescents, it becomes crucial to consider the presence of allergic diseases. [ABSTRACT FROM AUTHOR]

Background: As female social participation increases, the importance of femininity in leadership also increases. In Korea in 2021, 26.8% of 132,013 doctors and 35.1% of 3,099 medical students were female. However, no research has been conducted on the gender demographics of medical leaders. This study aims to define Korean medical leadership, investigate the gender ratio, and determine whether the proportion of women leaders differs in the academic and non-academic worlds. Methods: Korean medical leaders were defined as those in director or higher-level positions in organizations affiliated with the Korean Medical Association, 34 organizing societies under the Korean Academy of Medical Sciences (KAMS), and those who held dean and vice dean positions in 40 medical schools. Academic societies comprised KAMS, KAMS-affiliated societies, and medical schools; the rest were classified as non-academic organizations. Data were collected through website, e-mail, or telephonic surveys. Differences in the number of women leaders between academics and non-academics were analyzed using the chi-square test. Results: In total, 1,863 medical leaders were evaluated, with females accounting for 12.6%. The difference in the ratio of female leaders between academic and non-academic societies was not statistically significant (13.1% academic vs. 11.8% non-academic; P=0.445). Conclusion: The proportion of women leaders in the Korean medical field is relatively low compared with that of female doctors and medical students. The number of women in leadership positions and their effect on medical society will be observed periodically. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the effects of neuromuscular electrical stimulation (NMES) with gastrocnemius (GCM) strength exercise on foot morphology in patients with stroke. Herein, 31 patients with chronic stroke meeting the study criteria were enrolled and divided into two groups; 16 patients were randomized to the gastrocnemius neuromuscular electrical stimulation (GCMNMES) group, and 15 patients to the conventional neuromuscular electrical stimulation (CNMES) group. The GCMNMES group conducted GCM-strengthening exercise with NMES. CNMES group conducted NMES at paretic tibialis anterior muscle with ankle dorsiflexion movement. These patients underwent therapeutic interventions lasting 30 min/session, five times a week for 4 weeks. To analyze changes in foot morphology, 3D foot scanning was used, while a foot-pressure measurement device was used to evaluate foot pressure and weight-bearing area. In an intra-group comparison of 3D-foot-scanning results, the experimental group showed significant changes in longitudinal arch angle (p < 0.05), medial longitudinal arch angle (MLAA) (p < 0.01), transverse arch angle (TAA) (p < 0.01), rearfoot angle (RA) (p < 0.05), foot length (FL) (p < 0.05), foot width (FW) (p < 0.05), and arch height index (AHI) (p < 0.01) of the paretic side and in TAA (p < 0.05) and AHI (p < 0.05) of the non-paretic side. The CNMES group showed significant changes in TAA (p < 0.05) and FW (p < 0.05) of the paretic side and TAA (p < 0.05) and AHI (p < 0.05) of the non-paretic side. An inter-group comparison showed significant differences in MLAA (p < 0.05) and RA (p < 0.05) of the paretic side. In an intra-group comparison of foot pressure assessment, the experimental group showed significant differences in footprint area (FPA) (p < 0.05) of the paretic side and FPA symmetry (p < 0.05). The CNMES group showed a significant difference in only FPA symmetry (p < 0.05). An inter-group comparison showed no significant difference between the two groups (p < 0.05). Thus, NMES with GCM-strengthening exercises yielded positive effects on foot morphology in patients with stroke. [ABSTRACT FROM AUTHOR]

This study aimed to develop a problem-based learning program for occupational health nursing using smart learning, and to report the program's effects on occupational health knowledge and nursing professionalism. A quasi-experimental study was performed using a non-equivalent control group pre-test–post-test design. An occupational health nursing problem-based learning program using smart learning was developed, and students produced videos containing problem-solving strategies in groups. The experimental and control groups consisted of 34 and 29 participants, respectively. To collect data, an online survey was conducted before and immediately after the intervention. The experimental and control group's mean scores for occupational health knowledge before the intervention were 5.74 and 7.41, respectively. Additionally, the mean scores for nursing professionalism were 3.45 and 3.66. After the intervention, both the knowledge on occupational health and nursing professionalism score improved to 8.26 and 3.64 in the experimental group. This study reported significant improvements after conducting the occupational health nursing education program. These results demonstrate the need to develop a nursing education program for problem-based learning utilizing smart learning. Moreover, filming videos in cooperation with students can improve the effectiveness of education by improving knowledge. [ABSTRACT FROM AUTHOR]

Purpose: This study investigated palliative care physicians’ attitudes regarding social issues related to opioid use. Methods: An email survey was sent to 674 physicians who were members of the Korean Society for Hospice and Palliative Care (KSHPC). Results: Data from 66 physicians were analyzed (response rate, 9.8%). About 70% of participants stated that their prescribing patterns were not influenced by social issues related to opioid use, and 90% of participants thought that additional regulations should be limited to non-cancer pain. Under the current circumstances, pain education for physicians is urgently needed, as well as increased awareness among the public. Half of the respondents identified the KSHPC as the primary organization responsible for providing pain education. Conclusion: Palliative care physicians’ prescribing patterns were not influenced by social issues related to opioid use, and these issues also should not affect cancer pain control.

Background: Loneliness was found to be a commonly experienced feeling among older adults during the COVID-19 pandemic and is considered to be a high-risk factor for depressive symptoms. Maintaining meaning in life has been found to be a protective resource for mental health among older adults. The purpose of this study was to examine the mediating effects of an individual's meaning in life in the relationship between loneliness and depressive symptoms among older Korean adults. Methods: The data were obtained from a sample of 213 community-dwelling older adults aged over 65. The instruments were the UCLA Loneliness Scale, the Center for Epidemiologic Studies Depression Scale, and the Meaning in Life Questionnaire. Results: Loneliness was positively associated with depressive symptoms and negatively associated with the presence of and search for meaning among older adults. The presence of meaning mediated the relationship between loneliness and depressive symptoms but the search for meaning did not. The search for meaning mediated the relationship between loneliness and depressive symptoms through the presence of meaning. Conclusions: Our study findings suggest that efforts to reduce loneliness and improve meaning in life should be undertaken to prevent depressive symptoms among older adults. [ABSTRACT FROM AUTHOR]

Purposes: This study aimed to examine the discriminatory impacts of two major impairment factors—job presenteeism and attention presenteeism (JP and AP)—in presenteeism on burnout and to verify the multiple mediating effects of organizational and supervisory support in their causal relationship to provide theoretical and practical implications for alleviating burnout among rehabilitation medical workers (RMWs). Methods: Participants were convenience sampled from 23 hospitals and rehabilitation medical institutions in Korea, and 494 datasets were analyzed using the R packages R-studio, Jamovi, and JASP. Results: The significant effects of JP and AP on burnout were investigated; AP (0.609) had a much higher effect than JP (0.170) on burnout among RMWs. Moreover, the multiple mediating effects of organizational support and supervisory support were verified in the JP–AP relationship and burnout among RMWs. Additionally, the absolute effect on burnout was more from AP than JP, and organizational support had a far more significant effect than supervisory support in the process of affecting burnout. Conclusions: The present study contributes to the literature on burnout by examining the relationships between presenteeism and burnout and by extending the current understanding of burnout and presenteeism to RMWs. And it is practically important to understand that the effect of AP was greater than that of JP between the two key sub-factors of presenteeism affecting burnout among RMWs, and Korean RMWs are more affected by support from the organization system than by personal support from their boss. Related theoretical and practical implications are further elaborated. [ABSTRACT FROM AUTHOR]

Background: Many complex factors contribute to suicide in older adults. The suicidal ideation that precedes suicide is an especially direct predictor of suicide. This study aimed to identify the effects between variables affecting suicidal ideation among older adults using the International Classification of Functioning, Disability and Health (ICF) model and understand the causal relationships to systematize complex factors. Methods: This study used data from 9920 community-dwelling older adults who completed a national survey in 2020 to classify predictors of suicidal ideation (e.g., depression, subjective health status, sociodemographic factors, health factors, social support, instrumental activities of daily living (IADL), and social participation) by using the ICF model. To determine the causal relationship between variables, this study examined significance based on the critical ratio (C.R.) and squared multiple correlation (SMC) by using a path model. Results: Gender, education level, economic level, age, IADL, relationship satisfaction with a child, depression, and the number of chronic diseases significantly affected suicidal ideation, while age, employment status, participation in social groups, formal and informal support, satisfaction with a friend/neighbor relationship, and subjective health status did not significantly influence it. Moreover, depression mediated the relationship between each of these variables and suicidal ideation. Conclusions: It was found that depression was the most direct and mediating factor in suicidal ideation among many factors affecting the suicidal ideation of community-dwelling older adults. Additional studies should be conducted to develop community-level strategies based on these factors and understand causal relationships. [ABSTRACT FROM AUTHOR]

This study aimed to develop and validate a scale for measuring the therapeutic communication of nursing students. The scale development and evaluation study was conducted based on the scale development guidelines of DeVellis. A 47-item instrument was developed based on a review of the literature and interviews with 16 experts. Content validity was evaluated by ten nursing scholars, and the number of items was reduced to 35. The scale was administered to 352 nursing students from three regions in South Korea in 2022. Exploratory factor analysis and confirmatory factor analysis were performed on the scale items. Convergent validity, discriminant validity, and internal consistency reliability of the scale were evaluated. The factor analysis resulted in 15 items and two factors: relationship building and problem solving. Confirmatory factor analysis and evaluation of convergent and discriminant validity provided support for the validity of the two-factor Therapeutic Communication Scale in nursing students. The total scale demonstrated good internal consistency, with a McDonald's omega (ω) of 0.89. The Therapeutic Communication Scale is a reliable and valid measure that can be used to assess nursing students' therapeutic communication competence related to patient-centered nursing and provide foundational data to improve such skills.

Previous studies have reported that low levels of physical activity result in sarcopenic obesity (SO). However, the effects of specific intensities of physical activity on SO and the optimal amount of physical activity for lowering the prevalence of SO have not been well studied. This study aimed to identify the effects of physical activity levels and intensity on SO and the optimal amount of physical activity related to a lower prevalence of SO. This cross-sectional study used data from the nationwide Korean Frailty and Aging Cohort Study (KFACS), which included 2071 older adults (1030 men, 1041 women). SO was defined according to the criteria of the European Society for Clinical Nutrition Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO). Multivariate logistic regression analysis was performed to investigate the association between the physical activity level and SO. The high activity group had a significantly lower prevalence of SO than the non-high activity (low and moderate activity) group. On the other hand, moderate-intensity physical activity was associated with a lower prevalence of SO. A total physical activity energy expenditure of > 3032 kcal/week (433 kcal/day) for men and 2730 kcal/week (390 kcal/day) for women was associated with a reduced prevalence of SO. The high physical activity and total physical energy expenditure described above may be beneficial for reducing the prevalence of SO. [ABSTRACT FROM AUTHOR]

This study compared the level of workplace violence experienced by personal healthcare workers in a district in Seoul, Republic of Korea, with those experienced by workers in office or service jobs. We matched 150 personal care workers with 150 office workers and 150 service workers using a propensity score. Workplace violence was categorized into psychological violence and physical violence. Of the surveyed personal care workers, 53.3% reported experiencing psychological violence, and 42.0% reported experiencing physical violence. After adjusting for self-reported work-related symptoms, personal care workers had significantly higher odds of experiencing psychological violence than office workers (OR = 5.01; 95% CI: 2.80–8.97) or service workers (OR = 7.54; 95% CI: 3.93–14.47). The adjusted odds for physical violence were also significantly higher for personal care workers compared with those for office workers (OR = 5.83; 95% CI: 2.96–11.50) and service workers (OR = 6.00; 95% CI: 2.88–12.49). In terms of specific types of workplace violence, personal care workers were 7–10 times more likely to experience unwanted sexual attention, sexual harassment, and physical violence than office or service workers. We found that personal care workers were more prone to workplace violence than office or service workers, with gender-based or physical violence being the most common types. Considering the negative impact of workplace violence on workers' well-being and health services, policy updates and interventions focusing on personal care workers are needed to reduce workplace violence, safeguard workers' rights, and establish a secure working environment.

This study describes the use of a smartphone application based on the Korean version of the Mood Disorder Questionnaire in screening for bipolar spectrum disorders in a large general population. All data were collected between May 2011 and July 2011. A total of 27,159 individuals participated in the survey, using a smartphone application. The prevalence of positive screening results for bipolar spectrum disorders among 27,159 participants using the smartphone Korean Mood Disorder Questionnaire application was 8.2 percent. These results are similar to traditional paper-based results. The Korean Mood Disorder Questionnaire positive group exhibited more frequent occurrences of previous psychiatric treatment than the group with negative results. In a logistic regression analysis involving subjects with past psychiatric history, age group significantly predicted Korean Mood Disorder Questionnaire results. The smartphone application may be a useful screening tool for bipolar spectrum disorders. This study included only individuals who actively participated, and thus, the possibility of a selection bias should be considered. [ABSTRACT FROM AUTHOR]

This study aims to develop and evaluate the effectiveness of nursing practice education using mobile learning or m-learning for nursing students. A nonequivalent control group post-test design was used. Overall, 42 nursing students participated in the study. A three-week nursing practice education program was developed using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model. The course was implemented on the basis of Gagne's nine instructional situations. The findings demonstrated improvements in clinical competency (t = 7.44, p < 0.001) and problem solving (t = 2.29, p = 0.028). Accordingly, the study recommends introducing m-learning in nursing practice education using tablet PCs, as part of a newer nursing practicum training strategy that takes into account the factors identified in this study. It is also suggested that a continuous m-learning approach and development plan for nursing students be prepared to achieve technically advanced nursing practice education. [ABSTRACT FROM AUTHOR]

Older adults engage in online activities for various purposes. An increasing number of studies are establishing connections between the purposes of internet use and their impacts on health outcomes. This study aimed to examine how the purposes of internet use affect self-rated health and depressive symptoms among Korean older adults. A nationally representative survey of community-dwelling older adults in Korea was used in the analysis (n = 5094). Instrumental internet use (using the internet to access various forms of information, services, and other resources) in Korean older adults was as common as interpersonal communication use, and the purposes of internet use were mainly for information seeking for everyday needs and engaging in various activities for enjoyment. Internet use for interpersonal communication and instrumental purposes was significantly associated with depressive symptoms and self-rated health. Internet use for instrumental purposes had a greater impact on self-rated health (β = −0.186) and depressive symptoms (β = −0.160) compared with the impacts of interpersonal communication internet use on self-rated health (β = −0.101) and depressive symptoms (β = −0.047). The findings highlighted the necessity of designing interventions that take into account the different purposes of internet use for older adults in order to maximize its benefits, paying special emphasis for information seeking online.

Purpose: This study aimed to identify the general characteristics and health behaviors of students with non-therapeutic substance use. Methods: This secondary data analysis used data from the 17th Korea Youth Risk Behavior Web-based Survey (2021). Analyses of the 54,848 adolescents used descriptive statisics, the Rao--Scott χ² test, and logistic regression. Results: The risk factors for substance use among students were anxiety, loneliness, living separately from family, suicidal ideation, e-cigarette use, and high stress. Conclusion: The findings help identify the risk factors for non-therapeutic drug use among adolescents. Since South Korea does not have a drug prevention program for its adolescent population, an educational plan based on these findings could help prevent adolescent substance abuse.

Background: This study aimed to evaluate the association between chronic low back pain (CLBP) and chronic diseases, such as hypertension, diabetes, and dyslipidemia. Methods: This study was a retrospective analysis using data from the Korea National Health and Nutrition Examination Survey (KNHANES) between 2010–2012 and included women who answered a questionnaire in the KNHANES asking whether they had low back pain for ≥3 months. Participants were divided into non-CLBP and CLBP groups. For statistical analysis, the Student's t-test, chi-square test, Fisher's exact test, and logistic regression analysis were performed using SPSS. Results: Of 5961 participants, the non-CLBP group comprised 4098 women and the CLBP group comprised 1863. Adjusted logistic regression model revealed that dyslipidemia was positively associated with CLBP (odds ratio, 1.32; 95% confidence interval, 1.140, 1.530; p < 0.001). However, hypertension and diabetes were not associated with CLBP. Conclusions: Our results suggest that proper treatment of dyslipidemia may contribute to lowering the risk of CLBP later in life.

Background: Several studies have investigated the effect of antiemetics on postoperative nausea and vomiting (PONV) in high-risk groups. However, few studies have investigated the effect of antiemetics in patients at low risk of developing PONV. Methods: In this prospective, randomized, double-blinded trial, 177 patients undergoing surgery under general anesthesia were randomly allocated to three groups. Patients allocated to group C (control group) received 2 mL of intravenous 0.9% saline, those allocated to group R (ramosetron group) received 0.3 mg of intravenous ramosetron, and those allocated to group DR (ramosetron plus dexamethasone group) received 5 mg of intravenous dexamethasone and 0.3 mg of intravenous ramosetron. Results: Finally, 174 patients completed the study, and the types of surgeries were orthopedic (n = 80), rhinologic (n = 47), urologic (n = 29), and others (n = 18). The incidence of PONV up to 48 h postoperatively was significantly lower in group DR than in group C. The incidence of PONV up to 0–1 h postoperatively was significantly lower in groups R and DR than in group C. The usage pattern of rescue antiemetics was consistent with the incidence of PONV. The percentage of patients requiring rescue analgesics 0–1 h postoperatively was significantly lower in groups R and DR than in group C. Conclusions: The combination of dexamethasone and ramosetron demonstrated a superior effect in preventing PONV for 48 h after surgery under general anesthesia than saline in patients at low risk of developing PONV. Compared with saline injections, ramosetron injections yielded better outcomes for the incidence of PONV and the use of rescue antiemetics and rescue analgesics 0–1 h postoperatively. Trial registration: Clinical trial registration number: criskorea@korea.kr, KCT0006749. [ABSTRACT FROM AUTHOR]

Since the WHO's 2021 aging redefinition emphasizes "healthy aging" by focusing on the elderly's ability to perform daily activities, sarcopenia, which is defined as the loss of skeletal muscle mass, is now becoming a critical health concern, especially in South Korea with a rapidly aging population. Therefore, we develop a prediction model for sarcopenia by using machine learning (ML) techniques based on the Korea National Health and Nutrition Examination Survey (KNHANES) data 2008–2011, in which we focus on the role of socioeconomic status (SES), social infrastructure, and quality of life (QoL) in the prevalence of sarcopenia. We successfully identify sarcopenia with approximately 80% accuracy by using random forest (RF) and LightGBM (LGB), CatBoost (CAT), and a deep neural network (DNN). For prediction reliability, we achieve area under curve (AUC) values of 0.831, 0.868, and 0.773 for both genders, males, and females, respectively. Especially when using only male data, all the models consistently exhibit better performance overall. Furthermore, using the SHapley Additive exPlanations (SHAP) analysis, we find several common key features, which mainly contribute to model building. These include SES features, such as monthly household income, housing type, marriage status, and social infrastructure accessibility. Furthermore, the causal relationships of household income, per capita neighborhood sports facility area, and life satisfaction are analyzed to establish an effective prediction model for sarcopenia management in an aging population.

This study used the raw data from the Eighth Korea National Health and Nutrition Examination Survey (KNHANES-VIII), conducted under the supervision of the Ministry of Health and Welfare and the Korea Centers for Disease Control and Prevention in 2019. It was conducted to identify a significant correlation between physical activity (PA) and health-related quality of life (HR QOL) in the Korean population. In 2019, the KNHANES-VIII added the Health-related Quality of Life Instrument with 8 items (HINT-8) to assess the HR QOL. The independent variable is related to PA, specifically the presence or absence of PA, type of PA, and the frequency of PA. The dependent variable is HR QOL, measured either as the total score or specific items (e.g., pain, vitality, and memory) using the HINT-8 measurement tool. Demographic characteristics and health status may directly or indirectly influence the relationship between PA and HR QOL, which were used as covariates. A total of 4357 participants were included in the current study. The mean HINT-8 scores were significantly higher in the participants who performed PA on a weekly basis, leisure-related PA or MSPA, as compared with those who did not (p = 0.01 and <0.0001, respectively). In both the unadjusted and adjusted models, the mean HINT-8 scores were significantly higher in the participants who performed ≥500 MET-min/week of leisure-related PA as compared with those who did not (95% CI: 1.017–1.033; p < 0.001 and 95% CI: 1.005–1.02; p = 0.001, respectively). In both the unadjusted and adjusted models, the mean HINT-8 scores were significantly higher (95% CI: 1.015–1.03; p < 0.001 and 95% CI: 1.004–1.018; p = 0.003, respectively) in the participants who performed MSPA for ≥2 days/week as compared with those who did not. The current results confirmed that there is a significant positive correlation between the PA and HR QOL based on the HINT-8 scores. Because the HINT-8 was developed to assess the HR QOL in Koreans, however, further studies are warranted to evaluate its applicability to other ethnic populations. [ABSTRACT FROM AUTHOR]

Simple Summary: Research suggests that a skin condition called atopic dermatitis (AD) and cancer, specifically kidney cancer, might be connected. However, we do not have enough evidence to confirm this link. This study aimed to determine whether the risk is real and whether the severity of AD influences this association. We used a big database of health information from Korea for the investigation and found that people with moderate to severe AD have a higher-than-average chance of getting kidney cancer. This discovery could help doctors better understand these conditions and might lead to more frequent check-ups for kidney cancer in people with AD, especially those with severe disease. Background: Evidence for an association between atopic dermatitis (AD) and cancer is still insufficient. In particular, the association between the risk of renal malignancy and the severity of AD has not been thoroughly investigated. Objective: To investigate the risk of renal malignancy and determine the association between AD severity and cancer risk using data from the Korean National Health Insurance Service (KNHIS) database. Methods: We performed a population-based cohort study using the National Health Claims database from the NHIS in Korea. Results: We found a statistically significant association between AD and overall malignancy (for mild AD, hazard ratio (HR): 1.061, 95% confidence interval (CI): 1.006–1.118; for moderate to severe AD, HR: 1.061, 95% CI: 1.014–1.11) compared with the no AD group. The moderate to severe AD group showed a significantly increased risk for renal malignancy (adjusted HR: 1.533, 95% CI: 1.209–1.944) compared with the no AD group. Limitations: Patient inclusion is solely based on diagnostic codes. We had no data about drug use, genetic factors, or other medical history that could affect the cancer risk. Conclusion: In our large population-based cohort study, moderate to severe AD was associated with increased risk of renal malignancy. Regular check-ups for renal malignancy are recommended in this population. [ABSTRACT FROM AUTHOR]

Aim. This study aimed to (a) examine the relationship between staff nurses' perceptions of patient safety rules and procedures and their patient safety performance and (b) investigate potential mediators of this relationship. Background. Implementation of effective management interventions to improve patient safety requires knowledge of the extent to which nurses' perceptions of a hospital's rules and procedures regarding patient safety affect their patient safety performance. Methods. This correlational study involved a secondary analysis of cross-sectional survey data collected from 1,053 staff nurses in South Korea. Structural equation modeling was employed to test the proposed mediation model. Five standardized measures were used to assess key study variables: patient safety compliance, patient safety participation, nurses' perceptions of patient safety rules and procedures, communication about errors, and coworker support. Cronbach's alpha values for the scales ranged from 0.82 to 0.90. Results. Nurses' perceptions regarding the usefulness and effectiveness of rules and procedures about patient safety were positively related to their patient safety performance, measured in terms of safety compliance and participation behaviors. Communication about errors and coworker support showed significant mediating effects on these relationships. Conclusions. The findings indicate that the implementation of effective and useful rules and procedures for improving patient safety would facilitate error communication and coworker support, enhancing nurses' patient safety performance. Implications for Nursing Management. Hospital administrators and nurse managers should consider how they can foster conditions in which nurses perceive rules and procedures regarding patient safety as useful and effective.

(1) Background: Hospitalists are healthcare providers who focus on hospitalized patients, but research on the roles of pediatric hospitalists is lacking. This study investigates the role of a supervisor-type hospitalist in a pediatric hematology/oncology ward at a tertiary children's hospital, assessing the impact on satisfaction levels among patient caregivers, resident physicians, and nurses. (2) Methods: A retrospective analysis and online surveys were conducted to assess satisfaction levels before and after the introduction of hospitalists in the Department of Pediatric Hematology/Oncology at Seoul National University Children's Hospital in the Republic of Korea. (3) Results: The introduction of hospitalists led to a 19.3% reduction in prescription error interventions over six months. Unexpected transfers to the intensive care unit decreased from 1.4% to 0.7% (p = 0.229). Patient caregivers reported elevated satisfaction levels with physicians (rated 8.47/10), and there was a significant enhancement in overall satisfaction among nurses (increasing from 3.23 to 4.23/5, p < 0.001). The majority of resident physicians (83.3%) expressed contentment with the hospitalist system, with 77% indicating an interest in transitioning to a hospitalist role. However, these resident physicians also expressed concerns regarding job stability. (4) Conclusions: Supervisor-type pediatric hospitalists have the potential to elevate satisfaction levels not only among patient caregivers but also among nurses and resident physicians, showing promise in improving medical care quality. Nonetheless, ensuring favorable perception and securing job stability within the hospitalist system are pivotal for achieving successful implementation. [ABSTRACT FROM AUTHOR]

The effect of Pilates on dysmenorrhea has been little studied. The purpose of this study was to evaluate the effect of Pilates on menstrual pain and symptoms, premenstrual syndrome, and risk factors of dysmenorrhea. Thirty young women with primary dysmenorrhea were randomly assigned into a Pilates group (PG; n = 15) and a waitlist control group (CG; n = 15). The Pilates was performed twice a week for 12 weeks. Menstrual pain and symptoms were measured by visual analogue scale (VAS) and the Cox menstrual symptom scale (CMSS), respectively. Premenstrual syndrome was assessed using the premenstrual symptoms screening tool (PSST). Additionally, back flexibility, hip muscle strength, sleep duration and quality, perceived stress, state-trait anxiety, and depression were evaluated. The VAS, CMSS severity and frequency, and PSST symptoms and functional impairments decreased in the PG compared to the CG (p < 0.001 or p < 0.01) with large effect sizes. Back flexibility and the strength of hip flexors, hip extensors, and hip abductors significantly increased in the PG compared to the CG (all p < 0.01) with large effect sizes. Sleep quality (p < 0.01) and stress (p < 0.05) improved in the PG. Sleep duration, anxiety, and depression did not change in either group. In conclusion, the 12-week Pilates intervention ameliorates dysmenorrhea, partly mediated by improved physical function and sleep quality. [ABSTRACT FROM AUTHOR]

In recent years, there has been a growing trend of obesity and dyslipidemia among young adult men in South Korea. Therefore, we aimed to identify the obesity-related factors of dyslipidemia among young adult men in Korea using 3-year data (2019–2021) from the 8th Korea National Health and Nutrition Examination Survey. We included 1559 eligible men aged 19–39 years and examined the association between dyslipidemia and participants' general characteristics, health-related characteristics, and food intake according to obesity status. Statistical analysis was performed using complex sample analysis with weighted household and individual data. The affecting factors of dyslipidemia included age, body image perception, stress, and waist circumference (WC) in the body mass index (BMI) < 25 kg/m2 group and age and WC in the BMI ≥ 25 kg/m2 group. To prevent and manage dyslipidemia in young adult men, interventions should be developed separately for the normal, underweight, and obese groups. Effective intervention requires measuring WC and focusing on body fat control. Moreover, regular screening of this population should be performed to ensure early diagnosis and management of dyslipidemia. [ABSTRACT FROM AUTHOR]

Objective. To evaluate the effect of mental practice (MP), mirror therapy (MT), and MP+MT on upper extremity function and activities of daily living performance in patients with stroke. Methods: A total of 25 participants were randomly assigned to receive MP (n=8), MT (n=8), or MP+MT (n=9). Outcomes were assessed before, during, and after intervention using the Fugl-Meyer Assessment (FMA) and the Action Research Arm Test (ARAT) for upper extremity function as well as the Korean version of the modified Barthel Index (K-MBI) and the Motor Activity Log (MAL) for activities of daily living performance. Results: After intervention, MP, MT, and MP+MT groups had significant improvement in scores of FMA, ARAT, MBI, MAL (all p<0.05). The improvement in scores of FMA, ARAT, MBI, MAL did not differ significantly among the three groups. Nonetheless, the improvement in scores was largest in the MP+MT group. Conclusion: MP, MT, and MP+MT can improve upper extremity function and activities of daily living performance in patients with stroke. The improvement is largest after MP+MT. [ABSTRACT FROM AUTHOR]

This study aimed to examine the comprehensive impact of five aspects of the nursing work environment as well as supervisory support, nurse characteristics, and burnout on intent to stay (ITS) among Korean hospital nurses. A cross-sectional questionnaire was distributed in seven general hospitals from May to July of 2019. Data were collected from a sample of 631 Korean nurses. The hypothesized model was evaluated using the STATA program for path models. Findings demonstrated that burnout played a mediating role on the relationships between the nursing work environment, supervisory support, nurse characteristics, and ITS. Burnout was the most influential predictor of ITS (β = −0.36, p < 0.001). Nurse participation in hospital affairs (β = 0.10, p = 0.044) and collegial nurse–physician relationships (β = 0.08, p = 0.038) had a direct effect on ITS. Supervisory support had a significant direct effect on ITS (β = 0.19, p < 0.001). Therefore, to increase nurses' ITS, it is necessary to improve their participation in hospital affairs and collegial relationships, as well as strengthen support from supervisors and reduce burnout.

Given the increase in stroke-related social costs, studies on survival and functional prognosis after stroke are urgently needed. Therefore, we investigated the relationship between the frequency of rehabilitation treatments in the acute and subacute phases of stroke and the long-term mortality of stroke survivors with mild-to-moderate disabilities. We performed a retrospective cohort study using data from the Korean National Health Insurance Service database. Our final cohort included 733 patients with national disability registration grades 4–6. The number of special rehabilitation treatment claim codes was used as a proxy for the frequency of rehabilitation treatments. Furthermore, we categorized the rehabilitation frequencies within 24 months of stroke onset as 1–50, 51–200, 201–400, and >400. The dependent variable was all-cause mortality, and it was evaluated from 24 to 84 months after stroke onset. Severe disability was associated with a lower long-term mortality rate in the chronic phase (p < 0.001). In the Cox regression analysis, severe disability, older age, male sex, and chronic kidney disease were independent risk factors for long-term mortality in patients with stroke and mild-to-moderate disabilities. However, the frequency of acute/subacute rehabilitation treatments did not significantly improve long-term mortality. Our results suggest that the association between rehabilitation frequency and lower long-term mortality for patients with mild-to-moderate stroke was inconclusive. Therefore, further study is needed to determine a better-customized rehabilitation treatment system for these patients. [ABSTRACT FROM AUTHOR]

Background: Patients with atrial fibrillation (AF) experience diverse symptoms such as palpitations, dizziness, and fainting that lead to depression, anxiety, and poor quality of life. Management of symptoms is fundamental for AF, and with the increasing prevalence of AF, studies on management of symptoms in patients with AF are needed. Objectives: This study aimed to assess symptom clusters according to symptom severity in patients with atrial fibrillation and evaluate the relationships between symptom cluster groups and the psychological distress and quality of life of these patients. Design: A descriptive survey was used in this study. Methods: A total of 175 patients were included in this study. Data regarding symptoms, psychological distress, and quality of life were obtained using structured questionnaires and analyzed using frequency and percentage, mean and standard deviation, cluster analysis, t-testing, Chi-square testing, Pearson's correlation coefficient, and multiple regression analysis. The Euclidean distance square of the hierarchical cluster was used to form symptom cluster groups. Results: Two groups of symptom clusters were formed based on the seven most common symptoms (i.e., chest palpitations, fatigue/tiredness, dizziness, lack of energy, pulse skipping, insomnia, and heavy breathing) of atrial fibrillation patients. Psychological distress and quality of life showed significant correlations with the symptom cluster groups (p < 0.001). Conclusion: Symptoms of atrial fibrillation increased patients' depression and anxiety, and further affected their quality of life. Therefore, management of symptoms is critical to maintaining a high quality of life. Nursing interventions based on the characteristics of symptom cluster groups must be developed and attempted.
