Fracture Risk Among Stroke Survivors According to Poststroke Disability Status and Stroke Type.

BACKGROUND: Stroke survivors face physical and cognitive challenges, leading to an increased dependency and a higher fall risk. We aimed to investigate the impact of poststroke disability and stroke type on fracture risk at various sites compared with matched controls. METHODS: This retrospective cohort study used data from the Korean National Health Insurance System database (2010-2018), including patients with stroke and 1:1 matched controls. Stroke survivors were grouped based on the presence and severity of their poststroke disability and stroke type. The primary outcome was a newly diagnosed fracture, analyzed by Cox proportional hazard regression analyses adjusting for potential confounders. RESULTS: Among 223 358 stroke survivors (mean age, 64.8±10.9 years; 61.2% men), 16 344 fractures occurred during a mean follow-up of 3.7±2.5 years. In matched controls (n=322 161; mean age, 65.4±11.2 years; 61.3% men), 20 398 fractures were identified. Stroke survivors had increased overall fracture risk compared with matched controls (adjusted hazard ratio [aHR], 1.40 [95% CI, 1.37-1.43]). Specifically, hip fracture risk was even greater in stroke survivors (incidence rate per 1000 person-years, 4.7 [95% CI, 4.5-4.8]; aHR, 2.42 [95% CI, 2.30-2.55]) than controls (incidence rate, 2.2 [95% CI, 2.1-2.3]). The risk of vertebral fractures (aHR, 1.29 [95% CI, 1.25-1.34]) and other fractures (aHR, 1.19 [95% CI, 1.15-1.23]) was also higher than that of the control group. Hip fracture risk was the highest among stroke survivors with severe poststroke disability (aHR, 4.82 [95% CI, 4.28-5.42]), although vertebral or other fracture risk was the highest among those with mild poststroke disability. No significant difference in fracture risk was found between hemorrhagic and ischemic stroke survivors when stratified by disability status. CONCLUSIONS: Our findings showed increased subsequent fracture risk among stroke survivors, particularly those with poststroke disability and for hip fracture. Bone health assessment and treatment should be emphasized as an essential part of stroke management.

Association between physical activity changes and risk of incident ischemic stroke following cancer diagnosis: A nationwide retrospective cohort study.

BACKGROUND: Physical inactivity is prevalent after cancer treatment, which could increase ischemic stroke risk in cancer survivors. This study investigated the association between physical activity change from pre- to post-diagnosis and ischemic stroke risk among cancer survivors. METHODS: Using data from the Korean National Health Insurance Service database, 269,943 cancer survivors (mean [SD] age, 56.3 [12.1] years; 45.7% male) with no history of cardiovascular disease were evaluated based on changes in physical activity from pre- to post-diagnosis. Using the Fine-Gray model, subdistribution hazard ratios (sHRs) and 95% confidence intervals (CIs) for ischemic stroke risk were calculated, considering death as a competing risk. RESULTS: After cancer diagnosis, 62.0% remained inactive, 10.1% remained active, 16.6% became active, and 11.4% became inactive. During a mean (SD) follow-up of 4.1 (2.0) years, being active both pre- and post-diagnosis was associated with a 15% decreased risk of ischemic stroke (sHR, 0.85; 95% CI, 0.75-0.96), compared with those who remained inactive. Cancer survivors who became active and inactive post-diagnosis showed a 16% and 11% lower ischemic stroke risk (sHR, 0.84; 95% CI, 0.75-0.93; sHR, 0.89; 95% CI, 0.79-0.99), respectively, than those who remained inactive. Analysis by the primary cancer site did not substantially differ from the main findings. CONCLUSIONS: Physical activity is associated with reduced ischemic stroke risk among cancer survivors. The potential benefits of physical activity are not limited to individuals who were physically active before cancer diagnosis, thus preventive strategies against ischemic stroke should emphasize physical activity throughout the cancer journey.

Glycaemic Status and Risk of Abdominal Aortic Aneurysm: A Nationwide Cohort Study of Four Million Adults using Korean National Health Screening Data.

OBJECTIVE: This retrospective cohort study aimed to confirm the previously reported inverse association between diabetes mellitus (DM) and abdominal aortic aneurysm (AAA) using large population based data. It also investigated the associations between AAA with impaired fasting glucose (IFG) and new onset DM (not yet treated). METHODS: A representative dataset was obtained from the Korean National Health Insurance Service. Participants who were aged ≥ 50 years and received a national health examination in 2009 were included and followed until 31 December 2019. Glycaemic status was defined based on fasting plasma glucose level and the relevant diagnostic codes. AAA was ascertained using records of medical facility usage with relevant diagnostic codes or aneurysm repair surgery. A Cox proportional hazards model was used to examine the association between glycaemic status and AAA, with adjustment for confounders. Additionally, the interactions between glycaemic status and subgroups based on baseline characteristics were examined. RESULTS: The study population comprised 4 162 640 participants. Participants with IFG or DM were significantly more likely to be male, older, and have comorbidities compared with normoglycaemic participants at baseline. The incidence of AAA was lower in participants with IFG or DM compared with normoglycaemic participants. The AAA risk was lower in patients with DM than in patients with IFG, and decreased linearly according to glycaemic status: the adjusted hazard ratio was 0.88 (95% confidence interval [CI] 0.85 - 0.91) for IFG, 0.72 (95% CI 0.67 - 0.78) for newly diagnosed DM, 0.65 (95% CI 0.61 - 0.69) for DM duration < 5 years, and 0.47 (95% CI 0.44 - 0.51) for DM duration ≥ 5 years compared with the normoglycaemia group. Both IFG and DM were related to reduced AAA risk in all subgroups, suggesting an independent association. CONCLUSION: Both IFG and DM, even when not treated with antihyperglycaemic medication, were associated with a lower incidence of AAA. The AAA risk decreased linearly according to DM duration.

Metabolic dysfunction-associated steatotic liver disease and risk of esophageal cancer in patients with diabetes mellitus: a nationwide cohort study.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is closely associated with type 2 diabetes and a developing several cancers including esophageal cancer (EC). However, the association between MASLD and EC in diabetic patients has not been investigated. Therefore, we aimed to investigate the relation between MASLD and developing EC in diabetic patients. This was a population-based retrospective cohort study of data from the Korean National Health Insurance Service (NHIS). A total of 1,904,468 subjects diagnosed with diabetes who underwent NHIS-provided health checkups from 2009 to 2012 were included. We constructed a Cox proportional hazard model for the association of fatty liver index (FLI) and the risk of EC stratified by potential confounders. Over a mean follow-up duration of 6.9 years, the incidence of EC was higher in the high (≥60) FLI group compared to the low (<30) FLI group (14.4 vs. 13.7 event per 100,000 person-years). The risk of EC correlated with the degree of FLI, particularly in older (P = 0.002), female (P = 0.033), non-smoking (P = 0.002), and non-drinking patients (P = 0.025). Among obese patients, the risk of EC was not associated with FLI; however, the risk of EC was higher in the high FLI group in non-obese patients. Lean MASLD patients had the highest risk of EC (adjusted hazard ratio 1.78; 95% confidence interval, 1.5-2.13). MASLD was associated with an increased risk of EC in diabetic patients, and lean MASLD has the highest risk. Further studies are required to determine the causal relationship between MASLD and EC.

Development and effectiveness of a metaverse reality-based family-centered handoff education program in nursing students.

PURPOSE: Effective patient handoffs are vital in pediatric populations. This study aimed to develop and identify the impact of a metaverse-based handoff program using ZEPETO on nursing students' handoff competence, handoff self-efficacy, learning realism, and satisfaction. DESIGN AND METHODS: This study used a non-randomized, pre-post nonequivalent group design to develop, implement, and verify a metaverse-based handoff simulation program in a nursing school in South Korea. We assigned 69 senior nursing students from a university to an experimental group or a control group. We developed a metaverse-based, handoff simulation program of family-centered care by building a pediatric intensive care unit (PICU) using ZEPETO. The program included an online lecture, a metaverse rounding discussion, and a metaverse-based handoff simulation of postoperative care for infants with congenital heart disease. We measured handoff competence, handoff self-efficacy, learning realism, and learning satisfaction pre- and post-program. RESULT(S): The experimental group showed significantly higher handoff self-efficacy than the control group (t = 3.17, p = 0.002). No significant differences were found in handoff competency, learning realism, or learning satisfaction between the groups. CONCLUSION(S): This study confirmed that a family-centered care-based handoff metaverse simulation program based on the experiential learning theory enhanced nursing students' handoff self-efficacy. The program equipped students to conduct safe and effective handoffs in real-world clinical settings by providing an immersive learning experience and emphasizing patient-centered communication. PRACTICAL IMPLICATIONS: Based on these results, family-centered, handoff education programs are recommended to be developed that focus on learning realism and learning satisfaction to enhance nursing students' handoff competence.

Risk of CKD Following Detection of Microscopic Hematuria: A Retrospective Cohort Study.

RATIONALE & OBJECTIVE: Microscopic hematuria is an uncertain risk factor for chronic kidney disease (CKD). We investigated the association between persistent or single episodes of microscopic hematuria and the development of incident CKD, overall and separately among men and women. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: A total of 232,220 Korean adults without CKD at baseline who underwent repeated regular health examinations at Kangbuk Samsung Health Study formed the study cohort. EXPOSURE: Microscopic hematuria was defined by≥5 red blood cells per high-power field. Participants were categorized into 1 of 4 groups according to the presence of hematuria at 2 consecutive examinations: (1) no hematuria at both examinations (reference group); (2) hematuria followed by no hematuria (regressed hematuria group); (3) no hematuria followed by hematuria (developed hematuria group); and (4) hematuria at both examinations (persistent hematuria group). OUTCOME: CKD was defined as an estimated glomerular filtration rate<60mL/min/1.73m2 or proteinuria (1+or more on dipstick examination). ANALYTICAL APPROACH: Semiparametric proportional hazards models were used to estimate hazard ratios. RESULTS: During a 4.8-year median follow-up period, 2,392 participants developed CKD. Multivariable-adjusted hazard ratios for incident CKD, comparing the regressed, developed, and persistent hematuria groups to the no-hematuria group were 1.85 (95% CI, 1.35-2.53), 3.18 (95% CI, 2.54-3.98), and 5.23 (95% CI, 4.15-6.59), respectively. The association between persistent hematuria and incident CKD was stronger in men than women (P for interaction<0.001), although a statistically significant association was observed in both sexes. LIMITATIONS: Lack of albuminuria and inability to consider specific glomerular diseases. CONCLUSIONS: Men and women with microscopic hematuria, especially persistent hematuria, may be at increased risk of CKD.

A Web-Based Decision Aid for Informed Prostate Cancer Screening: Development and Pilot Evaluation.

BACKGROUND: Prostate-specific antigen-based routine screening is not recommended for the general population due to conflicting results with mortality reduction. We aimed to develop a web-based decision aid (DA) for informed decision making for prostate cancer screening. METHODS: Using the International Patient Decision Aid Standards (IPDAS) development process model, we developed our DA based on patient and clinician interviews and multidisciplinary expert discussions. The prototype consisted of predicting individual prostate cancer risk and informed decision-making, including knowledge, risk and benefit, cost, personal value, and decision making. We conducted a pilot study on 101 healthy men, evaluating the effectiveness of DA by measuring knowledge, attitude, and intention to screen before and after using the DA, as well as decisional conflict and usefulness after using the DA. RESULTS: Of the 101 participants (median age 60 [50-69] years), 84% had not undergone screening for prostate cancer in the past two years. After using the DA, knowledge on prostate cancer screening increased (mean score [of 10] before versus after: 6.85 ± 1.03 versus 7.57 ± 1.25; P < 0.001), and intention to not screen increased from 27.7% to 51.5% (P < 0.001), but attitude toward screening did not change (P = 0.564). After use of the DA, 79 participants reported no decisional conflict, and the usefulness score was high (mean score [of 100] 77.35 ± 7.69), with 85% of participants reporting that the DA helped with decision making. CONCLUSION: Our web-based DA yielded increased knowledge, decreased screening intention, and high perceived usefulness. These findings indicate potential clinical relevance, especially among younger individuals.

Factors influencing neonatal intensive care unit nurses' parent partnership development.

BACKGROUND: Neonatal nurses play an important role in the development of effective partnerships, as they have more consistent interactions with the patients' parents and can encourage parental involvement. This study aimed to identify factors influencing neonatal intensive care unit (NICU) nurses' development of partnerships with parents of high-risk infants in South Korea based on King's interacting systems theory. METHODS: We collected data utilizing a structured questionnaire, which included the following variables: developmental supportive nursing competency, empowerment, emotional intelligence, patient-centered communication skills, interpersonal competence, nursing work environment, and nurse-parent partnership. The participants were 140 pediatric nurses with at least one year of NICU experience in South Korea. We used SPSS/WIN 26.0 to analyze the data. FINDINGS: Of the factors evaluated, empowerment (ß = 0.35, p < 0.001), patient-centered communication skills (ß = 0.25, p < 0.01), interpersonal competence (ß = -0.27, p = 0.001), emotional intelligence (ß = 0.25, p = 0.005), age (ß = -0.15, p < 0.01), and gender (ß = 0.12, p = 0.03) explained 62.4% of the total variance of the nurse-parent partnership. Our results identify the factors affecting NICU nurses' development of partnerships with parents of high-risk infants. IMPLICATIONS FOR PRACTICE: Strategies and efforts to enhance the nurse-parent relationship must consider improving nurse empowerment, intelligence, and interpersonal factors.

Weight Change and the Development of Nonalcoholic Fatty Liver Disease in Metabolically Healthy Overweight Individuals.

INTRODUCTION: The study sought to investigate the effect of weight change on hepatic steatosis (HS) incidence with or without liver fibrosis in metabolically healthy overweight or obese individuals. METHODS: A cohort of 14,779 metabolically healthy men and women who were overweight or obese (body mass index ≥23 kg/m2) and free from HS and an intermediate or high probability of fibrosis at baseline were followed for a median of 5.2 years. Metabolic health was defined as freedom from the components of metabolic syndrome and a homeostatic model assessment of insulin resistance <2.5. Weight changes were calculated as differences from baseline at the next subsequent visit. The outcome was HS incidence, with or without liver fibrosis, as assessed by liver ultrasound and 2 noninvasive fibrosis scores. RESULTS: During 76,794.6 person-years of follow-up, 3539 cases of HS incidence were identified. The multivariable adjusted hazard ratios (95% confidence intervals) for HS incidence by weight change group, <-5.0%, -5.0%-1.0%, 1.0%-5.0%, and >5.0%, relative to the no weight change group (-0.9% to 0.9%) were 0.52 (0.44-0.60), 0.83 (0.75-0.92), 1.21 (1.10-1.33), and 1.51 (1.36-1.69), respectively. Clinically relevant weight loss of >5% was also associated with a lowered risk of HS with intermediate or high probability of advanced fibrosis. In mediation analyses, associations remained significant, although adjustment for metabolic risk factors was attenuating. DISCUSSION: Clinically relevant weight loss was associated with a reduced risk of developing nonalcoholic fatty liver disease with or without intermediate or high probability of advanced fibrosis in metabolically healthy overweight or obese individuals.

Factors affecting parent health-promotion behavior in early childhood according to family cohesion: Focusing on the COVID-19 pandemic.

PURPOSE: We investigated and compared the factors influencing parents' promotion of healthy behavior in young children according to their family cohesion level during the COVID-19 pandemic in South Korea. DESIGN AND METHODS: This was a cross-sectional study involving 432 parents of young children (ages 1-6) in six South Korean cities (320 and 112 from the high and low family cohesion groups, respectively). We collected data using self-report questionnaires on parents' health promotion behavior, stress, risk perception due to COVID-19, positive psychological capital, and family cohesion, and analyzed it using stepwise multiple regressions with the SPSS program. RESULTS: The factors influencing parents' health promotion behavior differed across the family cohesion groups. For the high group, family cohesion, positive psychological capital, gender, and stress significantly affected parents' health promotion behavior (adjusted R2 = 0.22, p < 0.001). Meanwhile, for the low group, positive psychological capital, gender, stress and parents' health status significantly affected parents' health promotion behavior (adjusted R2 = 0.19, p < 0.001). Thus, stress, positive psychological capital, and gender were common factors of parents' health promotion behavior overall, regardless of family cohesion. CONCLUSION: Our results are meaningful in finding that parents' health-related behaviors are not only affected by their individual factors, but also by family-related factors in the COVID-19 pandemic. PRACTICE IMPLICATIONS: The study results may act as a base for improving family-centered intervention programs to promote healthy behaviors in both parents and young children based on personal and family cohesion factors.

A structural equation model of developing a partnership between pediatric nurses and parents of children with cancer in South Korea.

PURPOSE: A trust-based cooperative partnership between pediatric nurses and parents of children with cancer is a significant factor in improving parents' coping abilities and reducing their anxiety. We aimed to identify factors and construct a structural equation model of developing a partnership between pediatric nurses and parents of children with cancer in South Korea. The model was based on Lazarus and Folkman's stress-coping-adaptation model. DESIGN AND METHODS: Data were collected utilizing a structured questionnaire, which included the following variables: parental stress, perceived nursing support, empowerment, coping, communication with nurses and nurse-parents partnership. The study participants included 205 parents of children diagnosed with cancer and receiving treatment as either inpatients or outpatients in South Korea. We used SPSS/WIN 26.0 to analyze the data and AMOS 26.0 to conduct the structural equation modeling. RESULTS: Empowerment (ß = 0.536, p = 0.001) and communication with nurses (ß = 0.169, p = 0.021) explained 26.0% of the total variance of nurse-parents partnership. CONCLUSIONS: The final model constructed here was confirmed to be suitable for explaining and predicting parent-nurse partnerships. Our results are meaningful in constructing partnership model between pediatric nurses and parents of children with cancer based on conceptual model. PRACTICAL IMPLICATIONS: Strategies and efforts to enhance communication with nurses and parental empowerment will be helpful for enhancing parent-nurse partnerships as children and parents go through the treatment process.

Association Between Frailty-Related Factors and Depression among Older Adults.

OBJECTIVES: We analyzed the association between individual frailty-related factors and depression in older adults. METHODS: A total of 796 older adults who underwent geriatric assessments were included in this cross-sectional study. The frailty-related factors studied were grip strength, physical activity, walking speed, weight loss, and recurrent falls. Depression was based on the Geriatric Depression Scale. RESULTS: After adjustment for covariates, recurrent falls were associated with depression in males (OR 3.84, 95% CI 1.30-11.35). Among females, weakest grip strength, slow walking speed, and weight loss were associated with depression (OR 2.61, 95% CI 1.52-4.49; OR 1.78, 95% CI 1.02-3.11; and OR 2.52, 95% CI 1.17-5.44, respectively). Having more frailty-related factors was also associated with higher odds of depression. CONCLUSIONS: The associations between individual frailty-related factors and depression differed among males and females. Further prospective studies on depression and individual frailty-related factors by sex may help elucidate specific targets to be prioritized for clinical assessment and intervention. CLINICAL IMPLICATIONS: Older adults affected by depression and frailty may present different clinical manifestations based on sex, and require different treatment approaches. Clinicians should assess both physical and psychological needs for integrated care in frail older adults.

Conditional relative survival and competing mortality in patients who underwent surgery for lung cancer: A nationwide cohort study.

We aimed to investigate the conditional relative survival (CRS) and competing mortality in patients who underwent surgery for newly diagnosed lung cancer. Using a nationwide population-based database, we calculated 5-year CRS on 1 to 5 years survival after surgery. These rates were reported according to age, sex, socioeconomic status, comorbidities and treatment received. We also estimated cause-specific mortality with the consideration of competing risk. We identified 34 349 patients newly diagnosed with primary lung cancer from 2007 to 2013. The 5-year CRS after surgery was 71.7% at baseline improving steadily to 85.4% by 5 years, suggesting evidence of persistent excess mortality risk. Throughout the period, lung cancer was the most common cause of death, contributing to 83.6% mortality 1 year after surgery and 66.3% 5 years after surgery. Other causes of death included cardiovascular disease and respiratory disease, which increased continuously with time after surgery. CRS rates for patients with lung cancer improved over time but did not reach the level of the general population even 5 years after surgery. Although the main cause of death continues to be lung cancer, death from noncancer causes increased with time after surgery. Evidence-based decisions could be made on the dynamic risk profiles of the patients.

Disparities in Liver Cancer Surveillance Among People With Disabilities: A National Database Study in Korea.

GOAL: The goal of this study was to determine disparities in liver cancer surveillance among people with disabilities is the goal of this study. BACKGROUND: Using the linked administrative database in Korea, we sought to investigate (1) whether there are disparities in liver cancer surveillance according to degree and type of disability and (2) temporal trends in liver cancer surveillance among people with disabilities. MATERIALS AND METHODS: We linked national disability registration data with national cancer surveillance data. We analyzed age-standardized participation rates for each year during the 2006-2015 period according to presence, type, and severity of the disability. We also examined factors associated with liver cancer surveillance by multivariate logistic regression using the most current data (2014-2015). RESULTS: The age-adjusted and sex-adjusted surveillance rate for liver cancer in people with disabilities increased from 25.7% in 2006 to 49.6% in 2015; however, during the same period, surveillance rate among people without disabilities increased from 24.9% to 54.5%. As a result, disparities in surveillance for liver cancer increased over time. The surveillance participation rate among people with disabilities was 12% lower than among people without disabilities. Surveillance rates were markedly lower among people with severe disabilities [adjusted odds ratio (aOR)=0.71] and people with renal disease (aOR=0.43), brain injuries (aOR=0.60), ostomy problems (aOR=0.60), and intellectual disabilities (aOR=0.69). CONCLUSIONS: Despite the availability of a national liver cancer surveillance program, a marked disparity was found in liver cancer surveillance participation, especially among people with severe disabilities, renal disease, or brain-related or mental disabilities.

A cross-sectional study of factors associated with influenza vaccination in Korean cancer survivors.

OBJECTIVE: To investigate factors associated with influenza vaccination in cancer survivors. METHODS: Study subjects were 1,945 Korean adult cancer survivors. Through medical record review and self-administered questionnaires, social and medical information was collected. Influenza vaccination was defined as ever having received a flu vaccine between one year before cancer diagnosis and the survey date. Multiple logistic regression analysis was used to evaluate factors associated with influenza vaccination. RESULTS: Overall, 60.8% of study subjects had received an influenza vaccination. Younger survivors had a significantly lower vaccination rate than did the elderly survivors (80.22% vs. 54.73%). In younger survivors, longer time elapsed since cancer diagnosis, lifestyle modification counselling during cancer treatment, adequate physical exercise (≥150 min/week) and complementary medication use were positively associated with vaccination, whereas extra-pulmonary cancers, multimodality (≥3) cancer treatment and higher educational achievement were inversely associated. In elderly survivors, fewer factors had a positive (adequate physical exercise) or inverse (multimodality cancer treatment and current smoking) association with influenza vaccination. CONCLUSION: Influenza vaccination rate was suboptimal, especially among younger cancer survivors. Targeted strategies are necessary to improve influenza vaccination in cancer survivors with consideration of individual characteristics such as age, lifestyle, cancer treatment modality, cancer type and education level.

Health behaviors of caregivers of childhood cancer survivors: a cross-sectional study.

BACKGROUND: Caregiving for childhood cancer survivors may be burdensome for caregivers and affect their physical health and health behaviors. However, studies examining health behaviors in caregivers of childhood cancer survivors are scarce. This study aimed to examine health behaviors of caregivers of childhood cancer survivors by comparing them with those of the general population, and analyze associated factors. METHODS: This study included 326 caregivers of childhood cancer survivors recruited from 3 major hospitals in South Korea and 1304 controls from the Korean National Health and Nutritional Examination Survey matched for age, sex, and education level. We compared health behaviors between the two groups by using conditional logistic regression analyses, and investigated factors associated with unhealthy behaviors in caregivers by using multiple logistic regression analyses. RESULTS: Caregivers were less likely to be physically inactive (aOR: 0.69, 95% CI: 0.51, 0.92) compared to controls, and this was more evident in women (aOR: 0.65, 95% CI: 0.45, 0.94). However, caregivers were more likely to be binge drinkers (aOR: 2.26, 95% CI: 1.73, 2.97), especially if they were men (aOR: 13.59, 95% CI: 8.09, 22.82). Factors associated with unhealthy behaviors in caregivers differed by the type of behavior. Current smoking risk was lower in female caregivers and in those with more comorbidities. Increasing age, female sex, higher education level, and lower household income were associated with lower risk of binge drinking. Higher household income and anxiety were associated with lower risk of physical inactivity, while depression was associated with higher risk of physical inactivity. CONCLUSIONS: Caregivers of childhood cancer survivors were more likely to engage in binge drinking, but less likely to be physically inactive. Strategies to promote adherence to desirable health behaviors in caregivers are needed with consideration of their socioeconomic and clinical factors, such as number of comorbidities.

Disparities in gastric cancer screening among people with disabilities: a national registry-linkage study in South Korea.

BACKGROUND AND AIM: Using the national disability registration linked to the cancer screening database in Korea, we examined (1) trends in the gastric cancer screening rate among people with disabilities over time, and (2) whether gastric cancer screening participation and modalities differed according to presence, severity, and type of disability. METHODS: We examined gastric cancer screening participation rates among individuals with registered disability, from 2006 to 2015. RESULTS: The age- and sex-adjusted rate for gastric cancer screening in people with disabilities increased from 25.9% in 2006 to 51.9% in 2015 (change: + 26.0%). During the same period, screening rates among people without disability improved from 24.7 to 56.5% (change: + 31.8%). Disability was associated with a screening rate [adjusted odds ratio (aOR) 0.89, 95% confidence interval (CI), 0.88-0.89]. Screening rates were markedly lower among people with severe disabilities (aOR 0.58, 95% CI 0.57-0.58) and people with autism (aOR 0.36, 95% CI 0.25-0.52), renal failure (aOR 0.39, 95% CI 0.38-0.39), brain injury (aOR 0.41, 95% CI 0.40-0.41), ostomy problems (aOR 0.53, 95% CI 0.51-0.55), intellectual disabilities (aOR 0.54, 95% CI 0.53-0.54), or mental disorders (aOR 0.55, 95% CI 0.54-0.56). The use of gastroscopy as the initial screening modality in people with disabilities was lower than in people without a disability. CONCLUSIONS: In spite of the availability of national gastric cancer screening program, we found significant disparities in gastric cancer screening participation, especially among people with severe disabilities and those with renal failure or brain-related/mental disabilities.

Association of smoking cessation after atrial fibrillation diagnosis on the risk of cardiovascular disease: a cohort study of South Korean men.

BACKGROUND: While smoking elevates the risk for cardiovascular disease (CVD) among atrial fibrillation (AF) patients, whether smoking cessation after AF diagnosis actually leads to reduced CVD risk is unclear. We aimed to determine the association of smoking cessation after AF diagnosis with subsequent CVD Risk among South Korean men. METHODS: This retrospective cohort study included 2372 newly diagnosed AF male patients during 2003-2012 from the Korean National Health Insurance Service database. Self-reported smoking status within 2 years before and after diagnosis date were determined, after which the participants were divided into continual smokers, quitters (smokers who quit after AF diagnosis), sustained-ex smokers (those who quit prior to AF diagnosis), and never smokers. Participants were followed up from 2 years after AF diagnosis until 31 December 2015 for CVD. Cox proportional hazards regression was used to determine the adjusted hazard ratios (aHRs) and 95% confidence interval (CIs) for CVD according to the change in smoking habits before and after AF diagnosis. RESULTS: The mean (standard deviation, minimum-maximum) age of the study subjects was 62.5 (8.6, 41-89) years. Among AF patients, quitters had 35% reduced risk (aHR 0.65, 95% CI 0.44-0.97) and never smokers had 32% reduced risk (aHR 0.68, 95% CI 0.52-0.90) for CVD compared to continual smokers (p for trend 0.020). Similarly, compared to continual smokers, quitters had 41% risk-reduction (aHR 0.59, 95% CI 0.35-0.99) and never smokers 34% risk-reduction (aHR 0.66, 95% CI 0.46-0.93) for total stroke (p for trend 0.047). Quitters had 50% reduction (aHR 0.50, 95% CI 0.27-0.94), sustained ex-smokers had 36% reduction (aHR 0.64, 95% CI 0.42-0.99), and never smokers had 39% reduction (aHR 0.61, 95% CI 0.41-0.91) in ischemic stroke risk (p for trend 0.047). The risk-reducing effect of quitting on CVD risk tended to be preserved regardless of aspirin or warfarin use. CONCLUSIONS: Smoking cessation after AF diagnosis was associated with reduced CVD, total stroke, and ischemic stroke risk.

Health service utilization, unmet healthcare needs, and the potential of telemedicine services among Korean expatriates.

BACKGROUND: With the significant growth of migration and expatriation, facilitated by increased global mobility, the number of Koreans living abroad as of 2016 is approximately 7.4 million (15% of the Korean population). Healthcare utilization or health problems, especially among expatriates in developing countries, have not been well researched despite the various health risks these individuals are exposed to. Consequently, we identified the health utilization patterns and healthcare needs among Korean expatriates in Vietnam, Cambodia, and Uzbekistan. METHODS: This cross-sectional survey examined 429 Korean expatriates living in Vietnam (n = 208), Cambodia (n = 60), and Uzbekistan (n = 161) who had access to the Internet and were living abroad for at least 6 months. A 67-item questionnaire was used, and feedback was received via an online survey program. Stepwise logistic regression analyses were performed to evaluate factors associated with unmet healthcare needs and preferences of certain type of telemedicine. RESULTS: We found that 45.5% (195/429) of respondents had used medical services in their country of stay. Among those who visited health institutions > 3 times, the most popular choice was general hospitals (39.4%, 15/38); however, they initially visited Korean doctors' or local doctors' offices. The most essential criteria for healthcare service facilities was a "skilled professional" (39.3%, 169/429), 42% wanted a health program for chronic disease management, and 30% wanted specialized internal medicine. A substantial number wanted to access telemedicine services and were willing to pay for this service. They were particularly interested in experts' second opinion (61.5%, 264/429) and quick, 24-h medical consultations (60.8%, 261/429). Having unmet healthcare needs and being younger was strongly associated with all types of telemedicine networks. CONCLUSIONS: Nearly half of the expatriates in developing countries had unmet healthcare needs. Telemedicine is one potential solution to meet these needs, especially in developing countries.

Shared decision-making in the paediatric field: a literature review and concept analysis.

AIM: The concept of shared decision-making is poorly defined and often used interchangeably with related terms. The aim of this study was to delineate and clarify the concept of shared decision-making in the paediatric field. METHOD: Rodgers and Knafl's evolutionary concept analysis was used to delineate and clarify the concept. Following a search of the CINAHL, PubMed and MEDLINE databases and online journals between 1995 and 2016, we included a total of 42 articles that referred to shared decision-making in the paediatric field. RESULTS: The attributes included active participation of the three: parents, children and health professionals; collaborative partnership; reaching a compromise; and common goal for child's health. Antecedents were existing several options with different possible outcomes; substantial decisional conflict; recognising child's health situations that decision-making is needed; and willingness to participate in decision-making. Finally, the consequences included decreased decisional conflict; mutual empowerment; improved child health status; and improved quality of paediatric health care. CONCLUSION: This study provides a theoretical understanding of the concept of shared decision-making in the paediatric field; furthermore, by integrating this concept into paediatric practice, it may help to reduce the gap between theory and practice. The analysis could also provide nursing researchers with insight into paediatric decision-making and establish a foundation to develop future interventions and situation-specific theory for promoting high-quality decision-making in the paediatric field.
