Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Revolutionizing Heart Failure Management With Artificial Intelligence: A Narrative Review of Diagnostic, Prognostic, and Therapeutic Innovations

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Heart failure (HF) remains a major global health burden, affecting over 64 million individuals worldwide. Early detection and optimal management are often limited by subjective interpretation of diagnostic tests and variable clinical expertise. Artificial intelligence (AI) has emerged as a transformative technology that can

Exploring heart rate variability as a biomarker for frailty: A narrative review

European Journal of Clinical Investigation, Volume 56, Issue 4, April 2026.
Frailty arises from progressive multisystem dysregulation, prompting interest in biomarkers that capture declining physiological reserve. This review positions heart rate variability (HRV) within this evolving biomarker landscape, outlining its physiological basis, analytical domains and relevance to clinical research.

Evaluating the Effect of a Sleep Prehabilitation Intervention in Patients Awaiting Elective Surgery: Protocol for a Single‐Blind Randomised Trial

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Adequate sleep health is critical for surgical recovery. Disrupted sleep can impede wound healing and cognitive performance and contribute to poor surgical outcomes. Preoperative intervention aimed at improving surgical outcomes is often referred to as prehabilitation and commonly uses exercise, nutrition or psychological intervention.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

Hypoxic Burden in Children With Sleep‐Disordered Breathing: Determinants and Correlates

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Hypoxic burden (HB) is an emerging metric for quantifying intermittent hypoxia associated with sleep apnea, offering potential advantages over traditional measures such as the apnea‐hypopnea index (AHI). This study evaluated the distribution and clinical significance of non‐respiratory event‐specific HB in children and adolescents with ...

Artificial Intelligence in Gastrointestinal Motility Diagnostics: A Systematic Review

Neurogastroenterology &Motility, Volume 38, Issue 4, April 2026.
Artificial Intelligence shows strong potential to improve the accuracy, efficiency, and standardization of gastrointestinal motility diagnostics. In time, this will improve patient care, but for now the referenced studies throughout the GI tract lack the required rigor for clinical implementation. ABSTRACT Background The assessment of gastrointestinal (

Validity and Reliability of the Heart Rate Matching Task: A Novel Measure of Heart Rate Estimation

Psychophysiology, Volume 63, Issue 4, April 2026.
ABSTRACT Sensing and monitoring changes in our heart rate is a key aspect of interoception. We introduce and test the construct validity of the Heart Rate Matching task (HRM), a novel, fast and accessible task designed to assess the ability to estimate heart rate, in both remote (i.e., online) and in‐lab settings.
