Regular physical activity (PA) is known to reduce the risk of serious community-acquired infections. We examined association PA with morbidity and mortality resulting from coronavirus disease (COVID-19) infection in South Korean population. Patients who tested positive for severe acute respiratory 2 underwent public health screening between 2014 2017 (

Abstract The major causes of death in patients with abdominal aortic aneurysm (AAA) are cardiovascular disease and cancer. purpose this study was to evaluate the effect AAA on long-term survival lung cancer patients. All patient data degenerative type over 50 years age during period 2009 2018 collected retrospectively from a National Health Insurance Service (NHIS) administrative database matched without by age, sex, metastasis, other comorbidities. Mortality rate compared between groups. A...

Cardiovascular disease (CVD) remains a global health challenge, primarily due to atherosclerosis, which leads conditions such as coronary artery disease, cerebrovascular and peripheral arterial disease. Mitochondrial dysfunction initiates endothelial dysfunction, key contributor CVD pathogenesis, well triggers the accumulation of reactive oxygen species (ROS), energy stress, cell death in cells, are crucial for atherosclerosis development. This review explores role PTEN-induced protein...

We describe two patients, with no previous history of vascular problems but poor lung function, who experienced septic shock due to bowel ischemia.Both were fed an enteral formula rich in fiber using a feeding tube and regular feeding.Surgical finding showed hemorrhagic ischemia the bowel.The pathologic suggests these changes may have been inspissations contents, which put direct pressure on mucosa wall, leading local impairment mucosal submucosal blood flow subsequent necrosis.Bowel...

This study aimed to evaluate the causal relationship between long-term outdoor air pollutants and incidence of peripheral arterial disease (PAD) using Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC) database. We included 292,091 subjects from general population who had previously not been diagnosed with PAD by NHIS-NSC 2008 2014. Hourly pollutant data (particulate gaseous) climate were collected. Correlation analysis collected confirmed pollution incidence. For...

The aim of this study was to analyze anatomical popliteal artery entrapment syndrome (PAES) and individualize the treatment condition according status adjacent structure.A total 35 PAES legs in 23 consecutive patients treated within Asan Medical Center, Seoul, Korea between 1995 2011 were analyzed retrospectively. Anatomical diagnosed by MRI and/or CT scans knee joint, or conventional transfemoral arteriography lower extremities.We noted a type II gastrocnemius medial head (GNM) anomaly, III...

Recent several reports have demonstrated that periodontitis is prevalent and adversely affects the survival in patients with chronic kidney disease (CKD) or end-stage disease. However, its impact on transplant outcomes remains uncertain.This retrospective cohort study included 136 167 patients, respectively, who underwent living donor transplantation (KT) at Seoul National University Hospital from July 2012 to August 2016 Korea April 2008 October 2018. We divided into three groups according...

The purpose of this study was to analyze the link between PTLD incidence and its occurrence time in patients at a single center comparable medical environments after 2000.Retrospectively, total 3305 kidney transplantation data were analyzed. Patients divided into two groups based on period from day diagnosis. Early-onset defined as development within years transplantation, whereas all other cases categorized late-onset PTLD.In early-onset group, young age (0-19 years) confirmed risk factor...

Abstract Background Although recipients and donors in living kidney transplantation experience psychological distress—including depression anxiety—during the pre-operative period, very few studies have evaluated related reactions. This study aimed to determine characteristics correlations of mood states personality (genetically unrelated) transplantations. Methods A total 66 pairs were enrolled from April 2008 June 2019 this study, whom 53 eligible included retrospective analysis their...

Purpose: Endotension is a rare late complication characterized by an increase in sac size without any type of endoleak following endovascular aortic aneurysm repair (EVAR).Due to its rarity, few studies have demonstrated the mechanism behind and management endotension.In this study, we aimed better understand treatment long-term outcome endotension single-center cohort.Materials Methods: This study was designed for retrospective review patients diagnosed with between January 2006 December...

Percutaneous vertebroplasty (PVP) is a minimally invasive surgical treatment for patients with osteoporotic vertebral compression fracture (OVCF) and can rapidly alleviate pain, improve mobility, stabilize the vertebrae.
