Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

Beyond the Heart‐Lung Axis: A Review of the Crosstalk Between the Hemodynamic, Neurohormonal, and Immune Systems in Pulmonary Hypertension

open access: yesComprehensive Physiology, Volume 16, Issue 5, October 2026.
Pulmonary hypertension is driven by dynamic crosstalk beyond the physical connection between the heart and lung, involving neurohormonal systems, immune pathways, and peripheral organs. This review highlights how multisystem signaling contributes to disease progression and may reveal new diagnostic and therapeutic targets.

Permanent Cardiac Pacing in Children: A 30‐Year Follow‐Up Retrospective Study in a Single Pediatric Asian Center

open access: yesJournal of Arrhythmia, Volume 42, Issue 5, October 2026.
This 30‐year retrospective study of pediatric permanent pacing found acceptable long‐term device complication rates, with epicardial leads used predominantly. Pacing‐induced cardiomyopathy occurred only in children with congenital heart disease, highlighting the need for individualized pacing strategies in this cohort and long‐term echocardiographic ...

Carcinoma hepatocelular após cirugía de Fontan: relato de caso

open access: yesGalicia Clínica
BACKGROUND: Single ventricle includes various cardiac abnormalities in which either one ventricle is underdeveloped or a ventricular septal wall did not form, leading to the mixing of arterial and venous blood in the heart. The Fontan procedure separates

The Hemi-Fontan operation: A critical overview

open access: yesAnnals of Pediatric Cardiology, 2014
The hemi-Fontan (HF) operation is a staging procedure in the journey towards an ultimate Fontan palliation. Although popular in the Western world, it has found limited application in the developing world.

Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

open access: yesArtificial Organs, Volume 50, Issue 10, Page 1360-1371, October 2026.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

Epicardial cardioverter defibrillator implantation due to post-fontan ventricular tachycardia

open access: yesAnnals of Cardiac Anaesthesia, 2020
Long-term survival of patients submitted to a Fontan procedure is reduced because of arrhythmias. Late post-Fontan ventricular tachycardia is extremely rare, but it can be fatal. Consequently, the implantation of an implantable cardioverter defibrillator

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1342-1354, September 2026.
ABSTRACT Purpose Hemodynamic monitoring is essential for patients with right‐sided congenital heart disease (CHD). Respiration may have an increased impact on pulmonary flow in these patients that cannot be assessed by standard tools including 4D flow MRI. This study uses 5D flow MRI to assess respiratory‐cycle variations in flow energetics in patients
