About the Lab

Professor Han Yeong Jeong's research lab specializes in cerebrovascular and metabolic diseases, with a focus on identifying biomarkers and inflammatory pathways linked to cerebral small vessel disease (cSVD), insulin resistance, and stroke outcomes. The lab investigates the role of metabolic markers such as the triglyceride-glucose (TyG) index, homocysteine, and systemic immune-inflammation index (SII) in predicting subclinical and clinical cerebrovascular pathology. They also explore the impact of premorbid nutritional status, particularly via the Geriatric Nutritional Risk Index (GNRI), on stroke prognosis. Their work bridges clinical neurology, metabolic health, and inflammatory biology using large-scale health check-up registries and prospective stroke cohorts.

High triglyceride-glucose index is associated with subclinical cerebral small vessel disease in a healthy population: a cross-sectional study
Ki‐Woong Nam, Hyung‐Min Kwon, Han‐Yeong Jeong, Jin‐Ho Park, Hyuktae Kwon, Su‐Min Jeong
SJR Q1Cardiovascular DiabetologyOA

BACKGROUND: The triglyceride-glucose (TyG) index is a marker of insulin resistance (IR) and has been associated with various metabolic syndromes, cardiovascular diseases, and cerebrovascular diseases. However, limited information is available regarding its association with subclinical cerebral small vessel disease (cSVD). In this study, we evaluated the relationship between the TyG index and cSVD, including silent brain infarcts (SBIs) and white matter hyperintensity (WMH). METHODS: We assessed

SJR Q1PLoS ONEOA

BACKGROUND: Premorbid undernutrition has been proven to have an adverse effect on the prognosis of stroke patients. The evaluation of nutritional status is important, but there is no universally accepted screen methodology. PURPOSE: We aimed to use the geriatric nutritional risk index (GNRI) for evaluating the effect of premorbid undernutrition on short-term outcomes in patients with acute ischemic stroke. METHODS: A total of 1,906 patients were included for analysis. Baseline characteristics we

SJR Q1PLoS ONEOA

BACKGROUND AND PURPOSE: Previous studies have reported that early hospital arrival improves clinical outcomes in patients with acute ischemic stroke; however, whether early arrival is associated with favorable outcomes regardless of reperfusion therapy and the type of stroke onset time is unclear. Thus, we investigated the impact of onset-to-door time on outcomes and evaluated the predictors of pre-hospital delay after ischemic stroke. METHODS: Consecutive acute ischemic stroke patients who arri

BACKGROUND: The research about the influence of triglyceride-glucose index on early prognosis in stroke is lacking. AIMS: In this study, we evaluated the association between triglyceride-glucose index and early neurological deterioration in patients with single subcortical infarctions. METHODS: Consecutive patients with single subcortical infarctions within 72 h of symptom onset between 2011 and 2015. Early neurological deterioration was defined as an increase of ≥2 in the total NIHSS score or ≥

SJR Q1Scientific ReportsOA

Systemic immune-inflammation index (SII) is a novel inflammatory marker based on the composition ratio of blood cell counts. In this study, we evaluated the association between the SII and cerebral small vessel disease (cSVD) in health check-up participants. We evaluated participants from our health check-up registry between 2006 and 2013. The SII was calculated using the following formula: SII = (platelet count × neutrophil count)/lymphocyte count. cSVD was assessed by considering white matter

SJR Q1StrokeOA

BACKGROUND AND PURPOSE: This study aims to investigate the association between insulin resistance (IR) and silent lacunar infarction (SLI) in healthy adults. METHODS: We recruited 2326 healthy Korean adults who took health checkups, including a brain magnetic resonance imaging. SLI was defined as an infarction measuring 0.3 to 1.5 cm in diameter that was localized in the territory of perforating branches of cerebral arteries, as seen in the brain magnetic resonance imaging.

BACKGROUND: The effectiveness of mechanical thrombectomy (MT) in cancer-related stroke (CRS) is largely unknown. This study aims to investigate the clinical and radiological outcomes of MT in CRS patients. We also explored the factors that independently affect functional outcomes of patients with CRS after MT. METHODS: We retrospectively reviewed 341 patients who underwent MT after acute ischemic stroke onset between May 2014 and May 2020. We classified the patients into CRS (n = 34) and control

SJR Q1International Journal of Stroke

Background Lifestyle changes and evolving healthcare practices in Korea have influenced disease patterns and medical care. Since strokes have high disease burden in countries with aging populations, it is necessary to evaluate the associated recent disease characteristics and patient care patterns. The Korean Stroke Registry is a nationwide, multicenter, prospective, hospital-based stroke registry in Korea used to monitor these changes across the population. Aims We aimed to evaluate the recent

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has led to changes in stroke patients' healthcare use. This study evaluated changes in Korean stroke patients' health-seeking behaviors and stroke care services using data from the Korean Stroke Registry (KSR). METHODS: We reviewed data from patients with acute stroke and transient ischemic attack (TIA) during 2019 (before COVID-19 period) and 2020 (COVID-19 period).

Abstract Ambient air pollution is one of the most important global health issues. Although several studies have been reported the associations between air pollution and brain function or structure, impact of the air pollution on cerebral small vessel disease (cSVD) have rarely been explored in Asian adult population. We evaluated the association between exposure to air pollutants and cSVD in Korean asymptomatic adults. This cross-sectional study included 3257 participants of a health screening p
