Late Extraction of Micra AV and Implantation of Right Atrial Leadless Pacemaker

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Tine‐based leadless pacemakers have been commercially implanted over the last 10 years. Retrieval of older devices is rarely discussed and based on rare case reports only. Methods A retrospective review of an extraction case of a Micra AV leadless pacemaker was performed. Internal Review Board approval was obtained.

An experimentally informed computational model of neurovestibular adaptation to altered gravity

open access: yesExperimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Venovenous extracorporeal membrane oxygenation catheter related superior vena cava syndrome without pre-existing stenosis in an adult patient: a case report

open access: yesBMC Pulmonary Medicine
Background The use of venovenous extracorporeal membrane oxygenation (VV ECMO) for severe adult respiratory failure is rapidly increasing worldwide. To date, no studies have documented early-onset superior vena cava (SVC) stenosis caused solely by ECMO ...

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

open access: yesExperimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

An age‐associated decline in the role of the sarcoplasmic reticulum and associated calcium‐handling proteins sets the pace for sinoatrial node function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stable, responsive pacemaking in the sinoatrial node is driven by the activity of the funny current (membrane clock), interplay of calcium cycling and release from the sarcoendoplasmic reticulum with depolarising sodium‐calcium exchange current (calcium clock). With increasing age, key proteins associated with calcium cycling are

Circulating microRNA signatures reveal core and reversible dysregulation in obesity via machine learning

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Machine learning analysis of circulating microRNA (miRNA) profiles identified a minimal set of biomarkers that distinguish individuals with obesity from lean individuals both before and after weight‐loss intervention. Comparative analyses revealed heterogeneous molecular responses to weight reduction, with some miRNAs showing ...

On the adaptive significance of group III/IV muscle afferent feedback for the cardiovascular response during sustained locomotion in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Group III/IV leg muscle afferent feedback has previously been recognized as an important determinant of the cardiovascular response to exercise lasting <5 min. Here we demonstrate that the activity of these neurons is crucial in regulating central and peripheral haemodynamic responses during steady state exercise of longer ...

Evaluation of Large Language Models in the Clinical Management of Patients With Upper Gastrointestinal Bleeding: Insights From Real‐World Patient Data

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
Large language models are evaluated for pre‐endoscopy risk stratification and prediction of endoscopic findings in patients with upper gastrointestinal bleeding. Their performance is compared with validated clinical risk scores, conventional machine learning models, and hybrid approaches.
