High Shear Stress Reduces ERG Causing Endothelial-Mesenchymal Transition and Pulmonary Arterial Hypertension.

Arterioscler Thromb Vasc Biol

February 2025

Department of Pediatrics (T.S., J.-R.M., Y.H.C., J.M.S., J. Kaplan, A.C., L.W., D.G., S.T., S.I., M.D., W.Y., A.L.M., M.R.).

Background: Computational modeling indicated that pathological high shear stress (HSS; 100 dyn/cm) is generated in pulmonary arteries (PAs; 100-500 µm) in congenital heart defects causing PA hypertension (PAH) and in idiopathic PAH with occlusive vascular remodeling. Endothelial-to-mesenchymal transition (EndMT) is a feature of PAH. We hypothesize that HSS induces EndMT, contributing to the initiation and progression of PAH.

Pharmacogenomics: DPYD and Prevention of Toxicity.

Clin Oncol (R Coll Radiol)

December 2024

NHS North West Genomic Medicine Service Alliance, UK; Manchester Centre for Genomic Medicine, St Mary's Hospital, Manchester University NHS Foundation Trust, Manchester, UK; The Division of Evolution, Infection and Genomics, School of Biological Sciences, University of Manchester, Manchester, UK.

In 2020, the introduction of pre-emptive DPYD genotyping prior to the administration of systemic fluoropyrimidine-based chemotherapy represented one of the first widespread pharmacogenetic testing programmes to be applied nationally in the United Kingdom. Pharmacogenetic variants in the DPYD gene found in between 3 and 6% of the population are a recognised cause of primary DPD enzyme deficiency and associated increased risk of severe fluoropyrimidine toxicity [1]. Yet, the availability of testing globally is heterogeneous.

Front Immunol

December 2024

The Catholic University Liver Research Center, Department of Biomedicine & Health Sciences, College of Medicine, The Catholic University of Republic of Korea, Seoul, Republic of Korea.

Background: Programmed death-ligand 1 (PD-L1) expression is abundant not only in malignant cells but also in infiltrating cells within the tumor microenvironment (TME) of hepatocellular carcinoma (HCC). This study explored the association between PD-L1 expression in TME and outcomes in HCC patients treated with atezolizumab plus bevacizumab (AB), emphasizing the implications of PD-L1 expression in both malignant and tumor-infiltrating cells.

Methods: This study included 72 patients with HCC who underwent percutaneous core needle liver biopsy before AB treatment between September 2020 and December 2023.

Background And Purpose: The magnetic resonance images (MRIs) ability of lesion detection in epilepsy is crucial for a diagnosis and surgical outcome. Using automated artificial intelligence (AI)-based tools for measuring cortical thickness and brain volume originally developed for dementia, we aimed to identify whether it could lateralize epilepsy with normal MRIs.

Methods: Non-lesional 3-Tesla MRIs of 428 patients diagnosed with focal epilepsy, based on semiology and electroencephalography findings, were analyzed.

Aims: Urinary tract infections are one of the most common reasons for antibiotic prescription. The widespread use of antibiotic treatments contributes to the global health problem of antimicrobial resistance development. To slow down the progression of antimicrobial resistance, it is essential that we explore nonantibiotic preventive treatments for this common condition.

Diagnostic efficacy of body roll test for lateral canal BPPV: A randomized controlled study.

Clin Exp Otorhinolaryngol

December 2024

Department of Otorhinolaryngology-Head and Neck Surgery, Incheon St. Mary's Hospital, College of medicine, The Catholic University of Korea, Seoul, Republic of Korea.

Background: Lateral semicircular canal BPPV (LC-BPPV) is diagnosed by the head roll test (HRT), in which the head is rotated to move particles in the lateral canal, causing nystagmus. The body roll test (BRT) is performed in a rolling position with the body and head together, which has the advantage of safely rotating the head at the correct angle in both directions. This study aims to assess the diagnostic utility of the body roll test (BRT).

Background: This study aimed to investigate the epidemiological characteristics and outcomes of myocarditis/pericarditis after BNT162b2 vaccination in Korean adolescents.

Methods: This was a retrospective cohort analysis of adolescents aged 12-19 years old diagnosed with myocarditis/pericarditis within 42 days of BNT162b2 mRNA vaccination. All reported cases were investigated by city or government epidemiologists and the diagnostic certainty and causality was determined by the Korea Disease Control and Prevention Agency's Adverse Event Following Immunization Expert Advisory Committee according to the modified version of Brighton Collaboration Myocarditis/Pericarditis Working group's case definitions.

Is severe medial knee osteoarthritis a risk factor for dissatisfaction following medial open-wedge high tibial osteotomy in patients 55 years of age or younger?

Orthop Traumatol Surg Res

December 2024

Department of Orthopaedic Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, 222, Banpo-Daero, Seocho-Gu, Seoul, 06591, Republic of Korea. Electronic address:

Introduction: Although previous studies have shown that severe medial knee osteoarthritis (OA) (Kellgren-Lawrence grade IV) is a risk factor for patient dissatisfaction following medial open-wedge high tibial osteotomy (MOWHTO), it is uncommon to perform arthroplasty as a primary surgical option in patients 55 years of age or younger. Thus, the purpose of our study was to evaluate whether severe medial knee OA is a risk factor for dissatisfaction following MOWHTO depending on patient age based on a cutoff of 55 years.

Material And Methods: We retrospectively reviewed the data of 270 consecutive patients who underwent MOWHTO with a minimum of 2 years of follow up.

Background: Complete revascularization has demonstrated better outcomes in patients with acute myocardial infarction (AMI) and multivessel disease. However, in the case of left main (LM) culprit lesion AMI with multivessel disease, there is limited evidence to suggest that complete revascularization is better.

Methods: We reviewed 16,831 patients in the Korea Acute Myocardial Infarction Registry who were treated from July 2016 to June 2020, and 399 patients were enrolled with LM culprit lesion AMI treated with percutaneous coronary intervention.

Integration of bulk and single-cell RNA-seq reveals prognostic gene signatures in patients with bladder cancer treated with immune checkpoint inhibitors.

Cancer Immunol Immunother

December 2024

Division of Biomedical Informatics, Seoul National University Biomedical Informatics (SNUBI), Seoul National University College of Medicine, Seoul, 03080, Republic of Korea.

Immune checkpoint inhibitors have significantly advanced research in oncology and are used to successfully treat patients with bladder cancer (BC). However, as the benefits of programmed death-1/ programmed death-ligand-1 blockade immunotherapy do not extend to all patients with BC, biomarkers are required to improve prognostic stratification. This study aims to identify reliable biomarkers to enhance the prediction of treatment outcomes.
