Purpose:
This study aimed to identify the incidence and related factors of delirium among cancer patients admitted to the general wards of a tertiary hospital.
Methods:
A retrospective analysis was performed on 9,749 adult cancer patients. Patients who screened positive for delirium were assessed using the Korean version of the Nursing Delirium Screening Scale (NuDESC). Data were analyzed using χ² tests, t-tests, and multiple logistic regression.
Results:
The incidence of delirium was 2.5% (n=243) based on screening results. Significant predictors included older age, longer hospital stays, emergency room admission, 90-day readmission, completion of life-sustaining treatment decisions, surgical department admission, altered consciousness (the strongest predictor), elevated white blood cell and blood urea nitrogen levels, and low albumin levels (p<.050).These 10 factors showed high discriminatory power for delirium (AUC=.91, 95% CI: 0.90~0.93).
Conclusion
The Nu-DESC should be actively utilized in clinical practice for early delirium detection. Nursing interventions must prioritize managing modifiable factors such as nutritional status, infection, and dehydration. Furthermore, case-sharing systems and regular education are essential to enhance nursing expertise and ensure patient safety.

Objective:
To examine the risk of cardiovascular disease (CVD) associated with use of tumor necrosis factor inhibitors (TNFi) in patients with ankylosing spondylitis (AS).
Methods:
This study used data from the Korean National Health Insurance database. Patients aged ≥18 years who were newly diagnosed with AS between 2010 and 2018 and did not suffer prior CVD were included. The primary outcome was a composite endpoint of myocardial infarction (MI) or stroke. The secondary outcomes were specific endpoints of MI, stroke, or congestive heart failure. TNFi use was evaluated as a time-dependent variable. Cox proportional hazard regression was used to examine the association between TNFi use and risk of incident CVD.
Results:
Of 19,775 patients (mean age, 36.1 years; 75% male), 5,978 (30.2%) were exposed to TNFi treatment during the study period. During a follow-up of 4.8 (interquartile range, 2.9~7.2) years, 522 events of MI or stroke occurred. TNFi use was associated with a lower risk of MI or stroke than no TNFi use after adjusting for traditional CV risk factors and medications (adjusted hazard ratio [aHR], 0.72; 95% confidence interval [CI], 0.55~0.94). The lower risk of MI or stroke associated with TNFi use was consistently observed across subgroups. Risk of congestive heart failure did not differ between users and non-users of TNFi (aHR, 0.94; 95% CI, 0.75~1.18).
Conclusion
In a real-world AS cohort, TNFi treatment was associated with a reduced risk of atherosclerotic CVD. However, TNFi use was not associated with risk of congestive heart failure.

Journal of Korean Academy of Nursing 2024;54(3):311-328
Purpose:
In this study a systematic review and meta-analysis investigated the impact of non-pharmacological interventions on major adverse cardiac events (MACE) in patients with coronary artery disease who underwent percutaneous coronary intervention (PCI).
Methods:
A literature search was performed using PubMed, Cochrane Library, EMBASE, and Cumulative Index to Nursing & Allied Health Literature databases up to November 2023. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. Effect sizes and 95% confidence intervals were calculated using R software (version 4.3.2).
Results:
Eighteen randomized studies, involving 2,898 participants, were included.Of these, 16 studies with 2,697 participants provided quantitative data. Non-pharmacological interventions (education, exercise, and comprehensive) significantly reduced the risk of angina, heart failure, myocardial infarction, restenosis, cardiovascular-related readmission, and cardiovascular-related death. The subgroup meta-analysis showed that combined interventions were effective in reducing the occurrence of myocardial infarction (MI), and individual and group-based interventions had significant effects on reducing the occurrence of MACE. In interventions lasting seven months or longer, occurrence of decreased by 0.16 times, and mortality related to cardiovascular disease decreased by 0.44 times, showing that interventions lasting seven months or more were more effective in reducing MI and cardiovascular disease-related mortality.
Conclusion
Further investigations are required to assess the cost-effectiveness of these interventions in patients undergoing PCI and validate their short- and long-term effects. This systematic review underscores the potential of non-pharmacological interventions in decreasing the incidence of MACE and highlights the importance of continued research in this area (PROSPERO registration number: CRD42023462690).

Background:
Large-scale studies about epidemiologic characteristics of renal infarction (RI) are few. In this study, we aimed to analyze the incidence and prevalence of RI with comorbidities in the South Korean population.
Methods:
We investigated the medical history of the entire South Korean adult population between 2013 and 2019 using the National Health Insurance Service database (n = 51,849,591 in 2019). Diagnosis of RI comorbidities were confirmed with International Classification of Disease, Tenth Revision, Clinical Modification codes. Epidemiologic characteristics, distribution of comorbidities according to etiologic mechanisms, and trend of antithrombotic agents were estimated.
Results:
During the 7-years, 10,496 patients were newly diagnosed with RI. The incidence rate increased from 2.68 to 3.06 per 100,000 person-years during the study period.The incidence rate of RI increased with age peaking in the 70s with 1.41 times male predominance. The most common comorbidity was hypertension, followed by dyslipidemia and diabetes mellitus. Regarding etiologic risk factor distribution, high embolic risk group, renovascular disease group, and hypercoagulable state group accounted for 16.6%, 29.1%, and 13.7% on average, respectively. For the antithrombotic treatment of RI, the prescription of antiplatelet agent gradually decreased from 17.0% to 13.0% while that of anticoagulation agent was maintained around 35%. The proportion of non-vitamin K antagonist oral anticoagulants remarkably increased from only 1.4% to 17.6%.
Conclusion
Considering the progressively increasing incidence of RI and high prevalence of coexisting risk factors, constant efforts to raise awareness of the disease are necessary. The current epidemiologic investigation of RI would be the stepping-stone to establishing future studies about clinical outcomes and optimal treatment strategies.

A 5-year-old Labrador Retriever presented with a subcutaneous mass on the right scapular region with localized calor. On magnetic resonance imaging (MRI), a heterogeneously hypointense mass was seen on T1-weighted images (WI) and hyperintense on T2WI and fat-suppressed T2WI with marginal contrast enhancement on postcontrast T1WI and invasion into the surrounding tissue. Histopathological examination of the mass confirmed subcutaneous mast cell tumor (MCT) infiltrating to the adjacent subcutaneous fat. This is the first report to describe the MRI findings of subcutaneous MCT in veterinary medicine. This study suggests that MRI may help evaluate the extent of invasion of subcutaneous MCT.

Purpose:
Cancer patients need ongoing care from healthcare providers to maintain continuity of treatment. Much research has been conducted on digital health services for providing continuous management of discharged cancer patients. This review aimed to identify nurse-led digital health interventions for discharged cancer patients.
Methods:
This scoping review was conducted using JBI methodology. The population was post-discharge adult cancer patients, the concept was nurse-led digital health intervention, and the context was open. Databases including PubMed, Embase, CINAHL, Cochrane Library, KoreaMed, and RISS were searched.Data were summarized about the general characteristics of the article, participants, interventions, and outcomes.
Results:
Fifty-seven studies were included, with ten studies that focused on the elderly. One third of the participants included in this review had colorectal cancer (32.7%). Telephone was the most frequently used format, while the others were applications, the internet, and telemonitoring. The nurses’ main roles consisted of counseling, symptom monitoring, and education.
Conclusion
The development of nurseled digital health intervention for the elderly will be necessary, and studies using more diverse technologies will need to be conducted. Digital health interventions for post-discharge colorectal cancer patients could be applied in practice. Nurses should provide emotional support while providing digital health interventions.

Clinics in Orthopedic Surgery 2022;14(4):500-506
Background:
Osteonecrosis of the femoral head (ONFH) involves young or middle-aged adults, and its incidence is increasing along with increasing use of steroids in the management of organ transplantation and adjuvant therapy for malignant neoplasms. To date, no pharmacological agent has been proven to prevent or retard the progression of ONFH, and surgical procedures including joint preservation procedures and hip arthroplasties are main treatments for the disease. Although ONFH is the most common or second most common disease for hip arthroplasty in East Asian countries, the trend of surgical procedures in this region remains unknown. Thus, we evaluated trends in surgical treatment of the disease in South Korea.
Methods:
We identified patients with ONFH from the Korean Health Insurance Review and Assessment (HIRA) database, a nationwide medical claims database of South Korea, between January 2007 and December 2018 and calculated the proportions of following surgical procedures at each year: total hip arthroplasty (THA), hemiarthroplasty (HA), core decompression/multiple drilling, femoral osteotomy, and vascularized bone grafting.
Results:
The total number of procedures increased from 3,824 in 2007 to 6,929 in 2018. Overall, the rate of THA (86%) was far greater than other procedures. From 2007 to 2018, the percentage of THA among the procedures increased from 80% to 91%, while that of joint preservation procedures decreased from 11% to 5%.
Conclusions
The total number of surgical procedures performed for ONFH increased and the percentage of THA increased, while that of joint preservation procedures decreased from 2007 to 2018 in South Korea.

Journal of Korean Medical Science 2021;36(17):e115-
Background:
We performed a prospective survey on the adverse reactions following the first dose of two types of vaccines against coronavirus disease 2019 (COVID-19) in healthcare workers (HCWs) in South Korea.
Methods:
HCWs at a tertiary referral hospital in Seoul, South Korea, received a chimpanzee adenovirus-vectored vaccine (ChAdOx1 nCoV-19) or an mRNA-based vaccine (BNT162b2) between March 5 and March 26, 2021. The HCWs were asked to report adverse reactions through a mobile self-report questionnaire for three days after vaccination.
Results:
A total of 7,625 HCWs received the first dose of ChAdOx1 or BNT162b2 vaccine during the study period. Of them, 5,866 (76.9%) HCWs (ChAdOx1, n = 5,589 [95.3%];BNT162b2, n = 277 [4.7%]) participated at least once in the survey, of whom 77% were female and 86% were younger than 50 years. The overall adverse reaction rate was 93% in the ChAdOx1 group and 80% in the BNT162b2 group (P < 0.001). Both local and systemic reactions were more commonly reported in the ChAdOx1 group, and the difference was larger in systemic reactions such as fever and fatigue. In the ChAdOx1 group, the incidence of adverse reactions was significantly higher in females and those in the younger age groups, while the BNT162b2 group showed such difference according to age.
Conclusion
In our prospective survey, vaccine-associated adverse reactions were more commonly reported in the ChAdOx1 group than in the BNT162b2 group. Females and younger age groups experienced vaccine-associated adverse reactions more frequently.
10.Association of Dietary Quality with Subjective Health-Related Perception and Chronic Diseases According to Age Segmentation of Korean Elderly
Korean Journal of Community Nutrition 2021;26(5):363-381
Objectives:
This study examined the Korean elderly’s dietary intake status, subjective health-related perception and chronic disease prevalence among age groups. Associations of dietary quality with subjective health-related perception and chronic diseases were also examined.
Methods:
Based on data from the 7th National Health and Nutrition Examination Survey, a total of 3,231 elderly were selected and categorized into 4 age groups of ‘65 ~ 69’, ‘70 ~ 74’, ‘75 ~ 79’ and ‘over 80’. Nutrient intakes, proportions of those with insufficient nutrient intakes, Korean Healthy Eating Index (KHEI), some subjective health-related perceptions and prevalence of major chronic diseases were compared according to the age groups. Differences in the subjective health-related perceptions and odds ratios of the chronic diseases according to the quartile levels of KHEI within the same age group were analyzed.
Results:
With the increase of age, several nutrient intakes (P < 0.001) and KHEI scores significantly decreased (P < 0.01). In women, activity restriction increased (P < 0.05), and EQ-5D score decreased with age (P < 0.001). Prevalence of hypertension (P < 0.0001), hypercholesterolemia (P < 0.05) and anemia (P < 0.01) significantly increased, while hypertriglyceridemia (P < 0.01) significantly decreased only in men. Obesity prevalence decreased, while underweight prevalence increased (P < 0.05). Subjective health status, EQ-5D score and PHQ-9 score significantly improved as KHEI score increased in certain age groups of women (P< 0.05). Odds ratio of hypercholesterolemia significantly increased with the increase of KHEI score in 65 ~ 69-year-old women. However, hypertension and anemia significantly decreased with the increase of KHEI score in 75 ~ 79-year-old women (P < 0.05).
Conclusions
The study findings suggest that nutrition management and policy for the Korean elderly need to apply a segmented age standard that can better reflect their dynamic characteristics.
