Potassium-Sodium Strategy Could Redefine Hypertension Fight
A perspective in The American Journal of Clinical Nutrition argues for a paradigm shift in hypertension prevention: boosting dietary potassium while reducing sodium can more effectively control blood pressure than sodium reduction alone, supported by evidence on potassium’s independent BP-lowering effect and the renal potassium switch; it recommends targeting sodium-to-potassium ratios in food reformulation, expanding education on potassium-rich foods, and policies to improve access to such foods, with potassium-enriched salt substitutes as a near-term option (not for those with kidney disease), while sodium reduction remains foundational.

2026 Guideline Unifies CKM Syndrome Care Across Specialties
The 2026 AHA/ACC/ADA/ASN guideline replaces the 2013 obesity guideline with a living, interdisciplinary framework for cardiovascular-kidney-metabolic (CKM) syndrome, emphasizing early risk detection (PREVENT equations), CKM staging, and routine metabolic and kidney health assessment across cardiology, endocrinology, nephrology, and primary care, with extensive clinician resources and supporting materials.
Living patient bridged by a gene-edited pig liver ahead of human transplant
A 56-year-old man with liver failure was connected to an externally perfused, genetically modified pig liver to keep him alive while awaiting a human liver transplant. The pig organ, engineered with six genetic changes to reduce rejection, functioned as a bridge for a few days; the patient subsequently received a human liver and is recovering. Researchers note the need for more details and that results should be published in a peer-reviewed journal.
Pomegranate Leaves Yield Molecule That Dismantles TTR Amyloid Fibrils
Researchers at Kumamoto University identified 1,2,3,4,6-penta-O-galloyl-β-D-glucose (PGG) from pomegranate leaves and branches that selectively dismantles preexisting transthyretin (TTR) amyloid fibrils in vitro, in vivo, and with patient-derived fibrils ex vivo, reducing deposits and improving healthspan and lifespan in a C. elegans model. Unlike amyloid-β, PGG targets TTR aggregates specifically, suggesting a promising natural lead for treating TTR amyloidosis, though safety and efficacy in humans remain to be established.
Selective CAR-T targets IGHV4-34, sparing healthy immunity in lymphoma mice
A CART4-34 CAR-T therapy targets the IGHV4-34 gene in B-cell cancer, destroying lymphoma cells in mice as effectively as CD19 CAR-T while sparing healthy B cells and avoiding immune suppression; the approach could also be used to treat autoimmune conditions such as lupus, but human trials are needed.
Fibroblast Niches Drive Crohn’s Fistula Formation
This study uses spatial transcriptomics and single-cell analysis to uncover how specialized fibroblast niches, particularly FAS cells, contribute to the formation, progression, and persistence of Crohn's fistulae, highlighting their roles in tissue remodeling, immune regulation, and epithelial regeneration, with implications for targeted therapies.
VEXAS Syndrome: UBA1 Mutations Drive Inflammation and Myeloid Bias
The study investigates how UBA1 mutations in VEXAS syndrome lead to inflammation and myeloid cell bias, revealing mechanisms involving aberrant cell death and ubiquitin pathway defects, and suggesting potential therapeutic targets.
mRNA COVID Vaccines Enhance Cancer Immunotherapy Effectiveness
COVID-19 mRNA vaccines enhance the effectiveness of immune checkpoint inhibitors in cancer treatment by stimulating innate and adaptive immune responses, increasing tumor PD-L1 expression, and potentially restoring immune sensitivity in 'cold' tumors, leading to improved survival outcomes in patients with NSCLC and melanoma.
Innovative Multi-Omics and Mapping Techniques Enhance Lung Cancer Treatment Predictions
This study develops spatial multi-omics and machine learning-based biomarkers to predict immunotherapy outcomes in advanced non-small cell lung cancer, highlighting the roles of immune cell spatial organization, macrophage PD-L1 expression, and gene signatures in resistance and response, validated across multiple cohorts.
Dana-Farber Develops AI-Powered Tool for Rapid Leukemia Classification
The article presents a rapid epigenomic classification method for acute leukemia using nanopore sequencing and machine learning, based on a comprehensive DNA methylation reference cohort, enabling faster and more precise diagnosis that can complement traditional diagnostic workflows.
Advances in Blood Pressure Regulation Post-Spinal Cord Injury Using ONWARD ARC-IM Therapy
The article investigates the neuronal basis of autonomic dysreflexia after spinal cord injury, identifying specific neuronal subpopulations and their reorganization that trigger this life-threatening condition, and explores therapeutic strategies like electrical stimulation to modulate these neural circuits.
