Pancreatic cancer cachexia promotes cardiac dysfunction through altered adrenergic signalling in the heart

The Journal of Physiology, Volume 604, Issue 15, Page 6281-6301, 1 August 2026.
Abstract figure legend The β1‐adrenergic receptor is the predominant adrenergic subtype expressed on cardiac myocytes. Upon stimulation it activates downstream signalling pathways that increase the heart rate and cardiac output to meet metabolic demands.

Morphological changes in the arterial pressure waveform following hemodynamic therapies in critical care: A clinical proof‐of‐concept study in older adults

Physiological Reports, Volume 14, Issue 15, August 2026.
In 132 cardiac surgery patients, fluid bolus, norepinephrine, and dobutamine each produced a distinct, recognizable pattern in arterial waveform morphology (systolic area/downstroke time, diastolic area/time, augmented pressure), suggesting arterial waveform analysis is a promising tool for bedside hemodynamic decision support.

A 17 Year Old With Developmental Delay Presenting With Increasing Confusion and Imbalance

Annals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1518-1523, July 2026.
ABSTRACT Methylmalonic acidemia is an autosomal recessive genetic disorder primarily caused by defects in methylmalonyl‐CoA mutase and cobalamin (vitamin B12) metabolism. These defects disrupt the tricarboxylic acid cycle and oxidative phosphorylation, leading to the abnormal accumulation of metabolic products such as methylmalonic acid, propionic acid,

Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 104-113, July 1, 2026.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Echocardiography‐Assisted Stenting of the Ductus Venosus in Infracardiac TAPVC: Report of a New Technique and Review of the Literature

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 214-220, July 1, 2026.
ABSTRACT Neonates with infracardiac total anomalous pulmonary venous connection (TAPVC) frequently require urgent treatment. If surgical repair is contraindicated due to extreme prematurity, interventional stenting of the ductus venosus (DV) has been introduced successfully to postpone surgery.
