Altered Neurovascular Coupling Dynamics During Dobutamine‐Induced Acute Stress

Brain and Behavior, Volume 16, Issue 9, September 2026.
ABSTRACT Background Neurovascular coupling (NVC) is essential for regulating brain metabolism and energy supply and may be altered under acute stress. This study aimed to investigate how acute stress induced by dobutamine affects NVC. Materials and methods This study enrolled 38 healthy participants undergoing a resting‐state fMRI scan and an arterial ...

Liver Transplantation Despite Active Intracranial Hemorrhage in Acetaminophen‐Induced Acute Liver Failure: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Acute liver failure with intracranial hemorrhage poses difficult transplant decisions. We report acetaminophen‐induced acute liver failure with cerebral edema and active multifocal hemorrhage successfully managed with emergent liver transplantation and staged neurosurgical intervention.

Posture‐Related Regional Homogeneity Abnormalities in Cerebral Small Vessel Disease: A Multi‐Position MRI Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Patients with CSVD showed higher upright ReHo in anterior cingulate gyrus (ACG) than NCs, and supine‐upright comparison revealed widespread ReHo alterations. Upright ACG ReHo and posture‐related ReHo changes in the hippocampus, putamen, and calcarine cortex were associated with poorer cognition and greater CSVD burden, suggesting that upright imaging ...

Neurocardiology: Brain–Heart Interactions in the Heart

MedComm, Volume 7, Issue 9, September 2026.
The heart and brain maintain systemic homeostasis through bidirectional communication involving neural, biochemical, and mechanical pathways. Dysregulation of these pathways contributes to a spectrum of conditions involving heart–brain interactions, including Takotsubo syndrome, the epileptic heart, stroke–heart syndrome, heart failure, cardiac ...

Oxygenaging: A Physiological Framework for Geroscience

Aging Cell, Volume 25, Issue 9, September 2026.
Mechanisms of aging disrupt oxygen homeostasis through three converging processes: oxygen‐cascade impairment, microvascular dysfunction, and molecular maladaptation. “Oxygenaging” integrates these domains to explain how declining oxygen delivery and utilization drive mitochondrial instability and amplify the effect of the hallmarks of aging.

Worsening of cerebral hyperemia by the administration of terlipressin in acute liver failure with severe hepatic encephalopathy [PDF]

, 2004
There is increasing evidence that terlipressin is useful in patients with cirrhosis and hepatorenal syndrome, but there are no data of its use in patients with acute liver failure (ALF) in whom hepatorenal syndrome is common.

Pediatric Neurosonology in Practice: Bridging Anatomy, Physiology, and Clinical Decision‐Making

Clinical Neuroimaging
Pediatric neurosonology is an important component of non‐invasive brain monitoring. The combination of transcranial and ocular ultrasound enables real‐time assessment of cerebral blood flow velocities, autoregulation, and intracranial dynamics across ...

Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

Artificial Organs, Volume 50, Issue 9, Page 1217-1227, September 2026.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

PFA Under Deep Sedation and Non‐Invasive Monitoring in Atrial Fibrillation Patients With Obstructive Sleep Apnea

Pacing and Clinical Electrophysiology, Volume 49, Issue 9, Page 1395-1402, September 2026.
ABSTRACT Background Clinical data about pulsed field ablation (PFA) under deep sedation among patients with obstructive sleep apnea (OSA) are limited, while the optimal periprocedural monitoring is not established. We report our experience in PFA among patients with atrial fibrillation (AF) and OSA, using a continuous non‐invasive respiratory and ...

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, Volume 111, Issue 9, Page 4223-4234, 1 September 2026.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...
