Association of low muscle mass and obesity with increased all-cause and cardiovascular disease mortality in US adults.

J Cachexia Sarcopenia Muscle

February 2024

Department of Internal Medicine, Hallym University Kangnam Sacred Heart Hospital, Hallym University College of Medicine, Seoul, Korea.

Background: Sarcopenic obesity, defined as the coexistence of low muscle mass and high adiposity, is associated with cardiovascular disease (CVD) and mortality. However, to what extent sarcopenia contributes to these risks independently or in conjunction with other cardiovascular risk factors remains unclear. This study aimed to investigate the association of low muscle mass, central obesity (COB), metabolic abnormalities, and their combinations with CVD and mortality risk.

Vector Borne Zoonotic Dis

January 2024

Department of Veterinary Public Health, College of Veterinary Medicine, Chonbuk National University, Jeonju, Republic of Korea.

This study investigated the IgG-specific humoral immune responses against specific antigen-like whole-cell antigen (WCA), outer membrane protein (OMP), periplasmic protein (PP), and cytoplasmic protein (CP) during the acute and subacute stages of biotype 1 infection in Sprague Dawley (SD) rats. The intraperitoneal method was used to experimentally infect forty-four 6- to 8-week-old SD rats with 1 × 10 colony-forming units (CFUs) of biotype 1. Following inoculation, the rat was serially sampled for serum at 0, 3, 7, 14, 21, 28, 35, 42, 60, 90, and 120 days.

Background: Relapsed or refractory peripheral T-cell lymphomas (r/r PTCLs) are a group of rare and aggressive diseases that lack effective therapies. Constitutive activation of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway is reported to be associated with PTCLs. Golidocitinib is an oral, potent JAK1 selective inhibitor evaluated in a phase I/II multinational study in patients with r/r PTCLs.

Prevalence, incidence, and outcomes of hepatitis E virus coinfection in patients with chronic hepatitis C.

Sci Rep

August 2023

Department of Internal Medicine, Seoul National University College of Medicine, Seoul National University Bundang Hospital, Seongnam, Gyeonggi, Republic of Korea.

This study aimed to elucidate the anti-hepatitis E virus (HEV) immunoglobulin G (IgG) prevalence and incidence of seroconversion and seroreversion as well as its risk factors and to analyze the clinical outcomes of HEV and hepatitis C virus (HCV) coinfected patients compared to those of HCV-monoinfected patients. We prospectively enrolled 502 viremic HCV patients with paired plasma samples (at intervals of ≥ 12 months) from 5 tertiary hospitals.

Identification of the Intestinal Microbes Associated with Locomotion.

Int J Mol Sci

July 2023

Department of Biomedical Sciences and Institute for Medical Science, Chonbuk National University Medical School, Jeonju 54907, Republic of Korea.

Given the impact of the gut microbiome on human physiology and aging, it is possible that the gut microbiome may affect locomotion in the same way as the host's own genes. There is not yet any direct evidence linking the gut microbiome to locomotion, though there are some potential connections, such as regular physical activity and the immune system. In this study, we demonstrate that the gut microbiome can contribute differently to locomotion.

Background: Substantial evidence indicates structural abnormalities in the cerebral cortex of patients with schizophrenia (SCZ), although their clinical implications remain unclear. Previous case-control studies have investigated group-level differences in structural abnormalities, although the study design cannot account for interindividual differences. Recent research has focused on the association between the heterogeneity of the cerebral cortex morphometric features and clinical heterogeneity.

Yonsei Med J

July 2023

Division of Cardiology, Department of Internal Medicine, Heart Vascular Stroke Institute, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea.

Article Synopsis
  • - A study examined the effects of atrial fibrillation (AF) on Korean patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI), focusing on its impact on mortality and pacemaker need after one year.
  • - Among 660 patients analyzed, those with AF had a significantly higher 1-year death rate (16.2%) compared to those in sinus rhythm (6.4%), indicating that AF is a strong predictor of worse outcomes.
  • - A large portion of AF patients (77.8%) received multiple antithrombotic therapies, with aspirin and clopidogrel being the most common combination, suggesting a need for careful management of these patients.

In this study, we investigated the effects of sodium propionate (SP) treatment on intracellular mechanism of murine macrophages and its contribution to host immunity during 544 infection. The intracellular growth assay revealed that SP inhibited replication inside the macrophages. To determine intracellular signaling involved during SP treatment after infection, we analyzed the change of five different cytokines production relevant to SP such as TNF-α, IL-10, IFN-γ, IL-1β, and IL-6, and the results indicated that the boost with IL-10 was apparent throughout the culture period for 48 h as well as IL-1β which was apparent at 24 h post-infection and IFN-γ which was apparent at 24 h and 48 h in comparison to SP untreated groups.

Background: Acute coronary syndromes are commonly caused by the rupture of vulnerable plaque, which often appear angiographically not severe. Although pharmacologic management is considered standard therapy for stabilizing plaque vulnerability, the potential role of preventive local treatment for vulnerable plaque has not yet been determined. The PREVENT trial was designed to compare preventive percutaneous coronary intervention (PCI) plus optimal medical therapy (OMT) with OMT alone in patients with functionally nonsignificant high-risk vulnerable plaques.
