The Association of Vitamin B-12 Plasma Concentration with Stroke Incidence According to Sex.

Background: Previous studies reported that vitamin B-12 deficiency is associated with an increased risk of stroke. However, studies examining the association between excessive vitamin B-12 and stroke risk are limited. Our study aimed to investigate the relationship between excessive vitamin B-12 concentrations and risk of stroke and explore whether this association varies according to sex.

Interaction Effect of Shift Work and Insomnia on Stroke Risk: A 19-Year Prospective Cohort Study in Korea.

Objectives: Our study aimed to investigate the association between shift work and stroke and determine whether this association varies depending on the presence of insomnia.

Methods: Utilizing the KoGES prospective cohort data, our primary exposure variables were shift work and insomnia. The occurrence of stroke was the main outcome of interest.

The current status and outcomes of in-hospital P2Y12 receptor inhibitor switching in Korean patients with acute myocardial infarction.

Background/aims: While switching strategies of P2Y12 receptor inhibitors (RIs) have sometimes been used in acute myocardial infarction (AMI) patients, the current status of in-hospital P2Y12RI switching remains unknown.

Methods: Overall, 8,476 AMI patients who underwent successful revascularization from Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) were divided according to in-hospital P2Y12RI strategies, and net adverse cardiovascular events (NACEs), defined as a composite of cardiac death, non-fatal myocardial infarction (MI), stroke, or thrombolysis in myocardial infarction (TIMI) major bleeding during hospitalization were compared.

Results: Patients with in-hospital P2Y12RI switching accounted for 16.

Simple parameters predicting extrahepatic recurrence after curative hepatectomy for hepatocellular carcinoma.

Extrahepatic recurrence (EHR) after curative hepatectomy for hepatocellular carcinoma (HCC) is associated with a poor prognosis. We investigated the features of EHR and identified its predictive factors. This retrospective study included 398 treatment-naive patients who underwent curative hepatectomy for HCC at two tertiary hospitals.

Endoscopic repair of delayed stomach perforation caused by penetrating trauma: A case report.

Background: Primary endoscopic closure of a perforated gastric wall during endoscopic procedures is mostly effective and well-tolerated; however, there are very few studies on the efficacy of endoscopic management of delayed traumatic gastric perforation. Herein, we report a novel case of a patient who was successfully treated for delayed traumatic stomach perforation using an alternative endoscopic modality.

Case Summary: A 39-year-old woman presented with multiple penetrating traumas in the back and left abdominal cavity.

Serum miR-214 as a novel biomarker for ankylosing spondylitis.

Objective: Serum microRNA (miR) in ankylosing spondylitis (AS) patients has been rarely identified. The objective of this study was to find AS-specific miR in sera of patients with AS.

Methods: Total RNAs were isolated from whole sera of patients with AS, patients with rheumatoid arthritis (RA), and healthy controls (HC) using miRNeasy Serum/Plasma Kit.

Clinical characteristics and outcomes in acute myocardial infarction patients with versus without any cardiovascular risk factors.

Background/aims: Although cardiovascular (CV) risk factors are well established, some patients experience acute myocardial infarction (AMI) even without any risk factors.

Methods: We analyzed total 11,390 patients (63.6 ± 12.

Influence of undernutrition at admission on clinical outcomes in patients with acute myocardial infarction.

Background: Although the effect of overweight or obesity on clinical outcomes in patients with acute myocardial infarction (MI) has been reported, the effect of undernutrition is not as well understood. Therefore, we investigated whether acute MI patients frequently present with undernutrition, and whether this influences poor clinical outcomes.

Methods And Results: Using the Korea Acute Myocardial Infarction Registry database, we screened initial data on acute MI patients admitted within 48h of symptom onset to a tertiary university hospital between November 1, 2011 and May 31, 2015.

Current trend of acute myocardial infarction in Korea (from the Korea Acute Myocardial Infarction Registry from 2006 to 2013).

Although the incidence of acute myocardial infarction (AMI) in Korea has been rapidly changed because of westernization of diet, lifestyle, and aging of the population, the recent trend of the myocardial infarction have not been reported by classification. We investigated recent trends in the incidence and mortality associated with the 2 major types of AMI. We reviewed 39,978 patients registered in the Korea Acute Myocardial Infarction Registry for either ST-segment elevation acute myocardial infarction (STEMI) or non-ST-segment elevation acute myocardial infarction (NSTEMI) from 2006 to 2013.
