Efficacy of Endovascular Thrombectomy in Acute Basilar Artery Occlusion with Low PC-ASPECTS: A Nationwide Prospective Registry-Based Study.

Objective: We evaluated the efficacy of endovascular thrombectomy (EVT) on the functional outcome of patients with acute basilar artery occlusion and low posterior circulation acute stroke prognosis early computed tomography score (PC-ASPECTS).

Methods: We identified patients with acute ischemic stroke due to basilar artery occlusion and PC-ASPECTS of 6 or less, presenting within 24 h between August 2008 and April 2022. The primary outcome was a favorable functional outcome, defined as a modified Rankin Scale (mRS) score of 0-3 at 90 days.

Long-Term Functional Outcome in Patients With Isolated Thalamic Stroke: The KOSCO Study.

Background: Information on the long-term prognosis in patients with isolated thalamic stroke is sparse. We report the functional outcomes of patients with thalamic stroke up to 24 months from the KOSCO (Korean Stroke Cohort for Functioning and Rehabilitation) study.

Methods And Results: Isolated thalamic stroke was defined as the presence of lesions solely in the thalamus, excluding cases with lesions in other brain parenchyma areas apart from the thalamus, as identified by brain magnetic resonance imaging or computed tomography scans.

Association between dementia diagnosis at dialysis initiation and mortality in older patients with end-stage kidney disease in South Korea.

Background: The prevalence of dementia is 2- to 7-fold higher among patients with end-stage kidney disease (ESKD) than among the general population; however, its clinical implications in this population remain unclear. Therefore, this study aimed to determine whether comorbid dementia increases mortality among older patients with ESKD undergoing newly initiated hemodialysis.

Methods: We analyzed data from the Korean Society of Geriatric Nephrology retrospective cohort, which included 2,736 older ESKD patients (≥70 years old) who started hemodialysis between 2010 and 2017.

Cross-cultural validation and measurement invariance of anxiety and depression symptoms: A study of the Brief Symptom Inventory (BSI) in 42 countries.

Background: Depression and anxiety are among the most prevalent mental health issues experienced worldwide. However, whereas cross-cultural studies utilize psychometrically valid and reliable scales, fewer can meaningfully compare these conditions across different groups. To address this gap, the current study aimed to psychometrically assess the Brief Symptomatology Index (BSI) in 42 countries.

Objective: We analyzed adult ADHD symptoms in a cross-cultural context, including investigating the occurrence and potential correlates of adult ADHD and psychometric examination of the Adult ADHD Self-Report Scale (ASRS) Screener.

Method: Our analysis is based on a large-scale research project involving 42 countries =72,627, 57% =32.84; =12.

Brain Frailty and Outcomes of Acute Minor Ischemic Stroke With Large-Vessel Occlusion.

Background And Purpose: The influence of imaging features of brain frailty on outcomes were investigated in acute ischemic stroke patients with minor symptoms and large-vessel occlusion (LVO).

Methods: This was a retrospective analysis of a prospective, multicenter, nationwide registry of consecutive patients with acute (within 24 h) minor (National Institutes of Health Stroke Scale score=0-5) ischemic stroke with anterior circulation LVO (acute minor LVO). Brain frailty was stratified according to the presence of an advanced white-matter hyperintensity (WMH) (Fazekas grade 2 or 3), silent/old brain infarct, or cerebral microbleeds.

Association of serum uric acid Levels with metabolic syndromes in Korean adolescents.

Introduction: The study findings investigated uric acid reference values and their association with a cluster of cardiometabolic risk factors among adolescents using the Korea National Health and Nutrition Examination Survey (KNHANES).

Methods: A retrospective cross-sectional study was conducted using the KNHANES database from 2016 to 2018, involving a total of 2,462 participants aged between 10 and 18 years. Based on age- and sex-specific percentile curves for serum uric acid (SUA) levels from the KNHANES, we examined the correlation between cardiometabolic risk factors and serum uric acid levels.

Sex differences of sequential changes in coronary blood flow and microvascular function in patients with suspected angina.

Aims: This study evaluated the sex differences of sequential changes in coronary blood flows and microvascular function in patients with suspected angina but with no obstructed coronary arteries.

Methods: A total of 202 consecutive patients who experienced chest pain but had no significant coronary artery stenosis and who underwent adenosine stress echocardiography were included in the study. Coronary blood flow (CBF) velocities were measured at 1, 2, and 3 min after adenosine infusion.

Hepatitis B Virus DNA-Level Change is Associated With Tumor Recurrence in Patients With Resected Hepatitis B Virus Hepatocellular Carcinoma.

Introduction: To investigate the significance of perioperative hepatitis B virus (HBV) DNA changes for predicting recurrence in patients with HBV-related hepatocellular carcinoma (HCC) undergoing liver resection (LR).

Methods: From 2013 to 2020, 241 patients with HBV-related HCC who underwent LR in five Hallym university-affiliated hospitals were enrolled. The serum HBV DNA level, together with other clinicopathological variables, was analyzed for association with HCC recurrence.

Moderate-intensity statin plus ezetimibe vs high-intensity statin according to baseline LDL-C in the treatment of atherosclerotic cardiovascular disease: A post-hoc analysis of the RACING randomized trial.

Background And Aims: Whether the effect of a combination strategy rather than increasing doses of one drug to lower low-density lipoprotein cholesterol (LDL-C) levels is consistent across baseline LDL-C levels remains uncertain.

Methods: In the RACING trial, which showed a non-inferiority of moderate-intensity statin with ezetimibe (rosuvastatin 10 mg with ezetimibe 10 mg) to high-intensity statin (rosuvastatin 20 mg) for the primary outcome (3-year composite of cardiovascular death, major cardiovascular event, or stroke), the heterogeneity in treatment effect according to baseline LDL-C levels was assessed for the primary and secondary outcomes (clinical efficacy and safety).

Results: Of 3780 participants, 2817 participants (74.

Photocoagulation Up to Ora Serrata in Diabetic Vitrectomy to Prevent Recurrent Vitreous Hemorrhage.

Purpose: To evaluate the role of performing photocoagulation up to ora serrata during vitrectomy in preventing recurrent vitreous hemorrhage (VH) in patients undergoing pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR).

Methods: This retrospective, nonrandomized study included 60 eyes from 60 patients who had undergone PPV for VH due to PDR. These patients were divided into two groups: group 1, those who underwent photocoagulation up to ora serrata using the scleral indentation technique during surgery; and group 2, those who did not undergo scleral indentation when photocoagulation and underwent photocoagulation up to vortex veins.

Subtypes of Patients with Mild to Moderate Airflow Limitation as Predictors of Chronic Obstructive Pulmonary Disease Exacerbation.

COPD is a heterogeneous disease, and its acute exacerbation is a major prognostic factor. We used cluster analysis to predict COPD exacerbation due to subtypes of mild-moderate airflow limitation. In all, 924 patients from the Korea COPD Subgroup Study cohort, with a forced expiratory volume (FEV1) ≥ 50% and documented age, body mass index (BMI), smoking status, smoking pack-years, COPD assessment test (CAT) score, predicted post-bronchodilator FEV1, were enrolled.

Prevalence and risk factors of low vitamin D levels in children and adolescents with familial hypokalemic periodic paralysis.

Unlabelled: Patients with familial hypokalemic periodic paralysis (HOKPP) experience episodes of reversible immobility and are at an increased risk of limited sunlight exposure, potentially leading to vitamin D deficiency. However, there is a lack of data on vitamin D levels in this population. We investigated serum vitamin D levels and their associated factors in children with HOKPP.
