Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

open access: yesExperimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

open access: yesExperimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Thermoregulatory and plasma neurobiomarker responses to heat tolerance assessment in exertional heat illness and matched controls

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise in the heat and elevated tissue temperature are associated with neuronal stress and changes in blood–brain barrier (BBB) function. More severe thermal insult may manifest as exertional heat illness (EHI) and complication by central nervous system (CNS) dysfunction may persist post‐EHI.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Kinematic‐calcium loops unravel impaired excitation–contraction coupling in MELAS‐affected cardioids

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Representation of kinematic and calcium transient loop with respect to traditional time coplotting. Abstract Impaired Ca2+ handling, and in particular leakage from the sarcoplasmic reticulum, is a critical mechanism in metabolic diseases affecting the heart.

“If You're Not Careful It'll Kill You”: Extreme Heat and Thermal Labor in Imperial Valley, California

open access: yesJournal for the Anthropology of North America, Volume 30, Issue 1, Spring 2027.
ABSTRACT Imperial Valley, California is among the poorest and hottest regions in the state, with summer temperatures routinely exceeding 100°F. For the 1000s of outdoor workers employed in agriculture, construction, and roofing, extreme heat poses a serious and often deadly risk. Climate change is projected to further intensify occupational heat stress,
