PURPOSE: The study was done to identify factors influencing Yangsaeng in elders. METHODS: Data were collected by questionnaires from 907 elders in D metropolitan city. Measures were Yangsaeng, perceived health status, self-efficacy, and self esteem. Data were analyzed using frequencies, means and standard deviation, t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression with SPSS/WIN 13.0 version. RESULTS: The mean score for Yangsaeng the participants was 3.56, out of a possible 5. There were significant differences in Yangsaeng according to age, education level, monthly income, marital status, family structure, and periodic health examination. Yangsaeng correlated positively with perceived health status, self-efficacy and self-esteem. According to the research, factors influencing Yangseng in elders were self-esteem, perceived health status, self-efficacy, family structure, and marital status. CONCLUSION: The positive correlation between Yangsaeng and health promotion behavior and perceived health status, self-efficacy, and self-esteem identified in this study can have an impact on strategies to improve the health of Korean elders. Therefore, the results can be used as a reference for future studies.

PURPOSE: As endovascular therapy (EVT) has been approved as a treatment guideline for acute ischemic stroke (AIS), it has been increasing in Korea. We conducted a nationwide survey to evaluate the current status of EVT for patients with AIS in Korea. MATERIALS AND METHODS: An electronic survey was sent to a representative clinician at each hospital where EVT was available in Korea. A Google survey was used to distribute the questionnaires and receive responses from October 2017 to December 2017. RESULTS: Among 120 hospitals in our society, 76 participated in this survey. In 26% of the hospitals, more than 50 annual cases of EVT were performed, and 25–50 annual cases in 37%. Fifty-six hospitals (73.7%) achieved successful recanalization (thrombolysis in cerebral infarction ≥2b) in more than 80% of patients. Computed tomography (CT) angiography was the most common imaging modality for AIS treatment, and magnetic resonance (MR) diffusion, MR-perfusion/diffusion, and perfusion CT were frequently used in order. Non-eligibility criteria for EVT included a National Institutes of Health Stroke Scale < 4 (64.5%), the absence of MR perfusion/diffusion mismatch (52.6%), and a low Alberta Stroke Program Early CT Score (42.1%). For anterior circulation stroke, 60% of Korean hospitals adopted a wider time range of “8 hours” from symptom onset, while 70% of hospitals had a time limitation of 12–24 hours for posterior circulation stroke. The most preferred EVT device was a stentriever (89.4%). In the failed cases due to underlying stenosis, 79% of Korean hospitals performed angioplasty or stenting for revascularization. CONCLUSION: This first nationwide survey showed that most Korean hospitals conducted EVT for AIS patients according to the present guideline in the era of mechanical thrombectomy by integrating the clinical experiences of many medical institutions and specialists.

PURPOSE: Although carotid endarterectomy (CEA) is recommended as a treatment for carotid stenosis rather than carotid artery stenting (CAS), CAS has been preferred in Korea. The aim of this study was to analyze long-term outcomes after CAS compared with CEA using Korean nationwide insurance data. MATERIALS AND METHODS: We obtained all data from the nationwide database of the Health Insurance Review & Assessment Service (HIRA) during the study period using several codes regarding the procedure or operation. We included the HIRA data, which included at least one-year follow-up after the procedures. The outcomes associated with both procedures were death, recurrence of ischemic stroke, and admission for cerebral hemorrhage. RESULTS: A total of 16,065 eligible patients who were treated with CAS or CEA between 1 January 2007 and 31 December 2016 were analyzed. The number of patients with CAS and CEA was 12,173 (75.8%) and 3,892 (24.2%), respectively. 8,976 patients (55.9%) were classified as symptomatic patients. CAS was associated with a higher risk of all-cause mortality (adjusted hazard ratio [HR], 1.282; 95% confidence interval [CI], 1.173–1.400). The adjusted rates for recurrent ischemic stroke and cerebral hemorrhage between CAS versus CEA were 24.9% versus 15.9% (HR, 1.474; 95% CI, 1.325–1.639) and 1.5% versus 0.9% (HR, 2.026; 95% CI, 1.322–3.106), respectively. In young symptomatic patients, there was no statistically significant difference in all-cause mortality and cardiovascular death between CAS and CEA. CONCLUSION: Our study using Korean nationwide insurance data demonstrated similar results to previous studies. Until further evidence of CAS is established through prospective studies, CAS should be performed in selected patients according to current guidelines.

Purpose: The purpose of this study was to evaluate trends in medical costs and prognosis in acute ischemic stroke (AIS) patients in Korea from 2008 to 2017 using medical claims data. Materials and Methods: All data for the past decade was collected from a big data hub provided by the Health Insurance Review & Assessment Service. Using several Korean Standard Classification of Disease codes, we estimated the number of patients, the costs of medical insurance, and prognosis according to the treatment with or without endovascular thrombectomy (EVT) among in-patients with AIS. Results: Since 2014, when EVT was covered by insurance, the number of patients who underwent EVT for AIS has increased significantly. Also, in the past decade, the medical costs following inpatient care for AIS with EVT have increased gradually, and the overall medical costs for the first year post-stroke have also increased. The prognosis of AIS patients with EVT was different according to the time of treatment. Annual trends for both mortality and cerebral hemorrhage after treatment of AIS with EVT have gradually decreased. Conclusion In this study, we found that both inpatient medical costs and 1-year cumulative medical costs have gradually increased, and the prognosis has gradually improved in patients receiving EVT treatment among AIS patients.

A rupture of a femoral pseudoaneurysm is an extremely rare complication of endovascular procedures, but its outcome can be life-threatening. In this report, we present a case of a femoral pseudoaneursym rupture in a patient in their early 90s following intra-arterial mechanical thrombectomy for acute ischemic stroke. Despite receiving medical and surgical interventions, the patient subsequently developed multiple organ failure, ultimately resulting in death. This case emphasizes the critical role of appropriate selection of vascular closure technique and careful post-procedural monitoring, particularly in high-risk patients.

PURPOSE: Clopidogrel is metabolized by the hepatic cytochrome P450 (CYP) system into its active thiol metabolite. CYP3A4 is involved in the metabolism of both clopidogrel and dihydropyridine calcium channel blockers (CCBs). A few reports have suggested an inhibitory interaction between CCBs and clopidogrel. Accordingly, the aim of this study was to determine the effect of CCBs on the antiplatelet activity of clopidogrel by serial P2Y12 reaction unit (PRU) measurements. MATERIALS AND METHODS: We assessed changes in antiplatelet activity in patients receiving both clopidogrel and CCBs for at least 2 months prior to enrollment in the study. The antiplatelet activity of clopidogrel was measured by VerifyNow P2Y12 assay in the same patient while medicated with CCBs and at 8 weeks after discontinuation of CCBs. After discontinuation of the CCBs, angiotensin receptor blockers were newly administered to the patients or dosed up for control of blood pressure. RESULTS: Thirty patients finished this study. PRU significantly decreased after discontinuation of CCBs (238.1+/-74.1 vs. 215.0+/-69.3; p=0.001). Of the 11 patients with high post-treatment platelet reactivity to clopidogrel (PRU> or =275), PRU decreased in nine patients, decreasing below the cut-off value in seven of these nine patients after 8 weeks. Decrease in PRU was not related to CYP2C19 genotype. CONCLUSION: CCBs inhibit the antiplatelet activity of clopidogrel.

PURPOSE: Changes in electroencephalography (EEG) patterns may offer a clue to the cause of altered mental status and suggest the prognoses of patients with such mental status. We aimed to identify the EEG patterns in patients with altered mental status and to correlate EEG findings with clinical prognoses. MATERIALS AND METHODS: We included 105 patients with altered mental status who underwent EEG. EEG and clinical chart reviews with ongoing patient follow-ups were performed to determine the clinical prognosis of the patients. Clinical data were sorted using the Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS). EEG findings were classified according to a method suggested by Scollo-Lavizzari. The EEGs were analyzed to find out whether any correlation existed with the prognoses of patients. RESULTS: Nonconvulsive status epilepticus (NCSE) was detected in only three patients (2.9%). Specific EEG patterns were observed in 28 patients. Twenty-nine (27.6%) patients expired, and 45 (42.9%) patients were in a vegetative state. EEG grade and GCS significantly correlated with GOS. EEG grade alone had a correlation with GCS. Patients with a severe EEG finding had a poor prognosis. CONCLUSION: EEG findings reflect the mental status of patients, and EEG grades are correlated with the clinical prognosis of patients. Although EEG is not frequently performed on patients with altered mental state, it can play a supplemental role in establishing a prognosis. Thus, the use of EEG should be emphasized in clinical setting.

OBJECTIVE: There are two established surgical treatment options for carotid artery stenosis. Carotid endarterectomy (CEA) has been accepted as a gold standard for surgical treatment while carotid artery stenting (CAS) has recently become an alternative option. Each treatment option has advantages and disadvantages for the treatment outcomes. We propose a protocol for selection of a proper surgical treatment option for carotid artery stenosis. MATERIALS AND METHODS: A total of 192 published articles on management of carotid artery stenosis were reviewed. Preoperatively considerable factors which had been repeatedly noted in those articles for the risk/benefits of CEA or CAS were selected. According to those factors, a protocol with four categories was established. RESULTS: CEA or CAS is indicated when the patient has a symptomatic stenosis > or = 50%, or when the patient has an asymptomatic stenosis > or = 80%. Each treatment option has absolute indications and favorable indications. Each absolute indication is scored with three points, and each favorable indication, one point. Based on the highest scores, a proper treatment option (CEA or CAS) is selected. CONCLUSION: We have been treating patients according to this protocol and evaluating the outcomes of our protocol-based decision because this protocol might be helpful in assessment of risk/benefit for selection of a proper surgical treatment option in patients with carotid artery stenosis.
