EuroSCORE II: Current limitations and physiological gaps in risk stratification
Abstract Risk stratification remains critical in cardiac surgery, enabling clinicians to predict adverse outcomes and guide perioperative management. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, introduced in 2011, incorporates 18 key variables to provide an evidence‐based approach to risk assessment.

Abstract Prolonged sitting inherent to long‐haul air travel can acutely decrease lower‐limb blood flow and increase brachial blood pressure. Healthy motion seating (HMS), which passively alters sitting interface pressure and posture, is a promising technology which may attenuate the deleterious effects of long‐haul air travel. The aim of this study was

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

How do physiological networks respond to normobaric hypoxia and isometric exercise?
Abstract The dynamics of physiological systems are impacted by both exercise and hypoxia. Network models can be used to map the interactions between various physiological components in environmental physiology and exercise using the concepts of information theory.

Abstract The magnitude of progressive augmentation (PA) and ventilatory long‐term facilitation (vLTF) are two forms of respiratory plasticity that are enhanced in some humans with obstructive sleep apnoea (OSA). This response might be linked to repeated nocturnal exposure to intermittent hypoxia or other traits connected to OSA.

Abstract Ageing is a risk factor for cardiovascular and neurodegenerative diseases. The myogenic response in resistance arteries is responsible for basal (myogenic) tone and blood flow autoregulation. G‐protein‐coupled receptors and G12/RhoA/Rho kinase are implicated in myogenic tone (MT), and we aimed to clarify their role in pressure sensing and ...

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...
