α-Ketoglutarate dehydrogenase is a therapeutic vulnerability in acute myeloid leukemia.

Perturbations in intermediary metabolism contribute to the pathogenesis of acute myeloid leukemia (AML) and can produce therapeutically actionable dependencies. Here, we probed whether alpha-ketoglutarate (aKG) metabolism represents a specific vulnerability in AML. Using functional genomics, metabolomics, and mouse models, we identified the aKG dehydrogenase complex, which catalyzes the conversion of aKG to succinyl CoA, as a molecular dependency across multiple models of adverse-risk AML.

Histamine N-methyltransferase (HNMT) as a potential auxiliary biomarker for predicting adaptability to anti-HER2 drug treatment in breast cancer patients.

Background: Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the efficacy of anti-HER2 drugs is insufficient.

Blood eosinophil count and treatment patterns of chronic obstructive pulmonary disease patients in South Korea using real-world data.

Background/aims: Chronic obstructive pulmonary disease (COPD) management guidelines have increasingly emphasised the importance of exacerbation prevention, and the role of blood eosinophil count (BEC) as a biomarker for inhaled corticosteroids (ICS) response. This study aimed to describe the distribution and stability of BEC and understand real-world treatment patterns among COPD patients in South Korea.

Methods: This was a retrospective database analysis using data obtained from the KOrea COPD Subgroup Study (KOCOSS) registry between January 2012 and August 2018.

Medication Hazards and Outcome Patterns of Pediatric Drug-Associated Liver Injury in Taiwan: An Analysis of 1998-2017 Spontaneous Adverse Drug Reaction Reports.

Background And Objectives: Accumulating pediatric efficacy and safety data on drug use is inherently challenging yet essential. This study aimed to analyze the frequency and compute the odds of pediatric drug-associated liver injury across age groups (early childhood, middle childhood, and adolescence) and therapeutic categories using adverse drug reactions (ADRs) reporting data spanning nearly two decades.

Methods: We analyzed the reports of suspected ADRs occurring in children and adolescents in the Taiwan National Adverse Drug Reaction Reporting System during the period from May 1998 until July 2017.

Echocardiography interpretation training and internal medicine milestones: A pilot study.

Background/purpose: The competency-based Internal Medicine Milestones (IMM) assesses physician training outcomes through six key competencies. This pilot study introduced IMM concepts through an echocardiography report interpretation course for postgraduate students (PGYs) and residents (Rs). We aimed to help young physicians understand and track competency development as they receive cardiovascular training, with a view to expanding IMM usage for all junior physicians.
