Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

open access: yesExperimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

Effects of a high‐sugar mixed meal on cerebrovascular haemodynamics in young, healthy versus middle‐aged adults with cardiometabolic risk factors

open access: yesExperimental Physiology, EarlyView.
Abstract Consumption of a high‐sugar mixed meal (HSMM) increases both glucose and insulin and elicits mixed vascular effects, with reduced microvascular blood flow but increased conduit artery diameter and blood flow. In this study, we sought to examine: (1) whether an HSMM elicits vascular segment‐specific effects within cerebrovasculature; and (2 ...

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial

open access: yesThe Journal of Physiology, EarlyView.
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 ...

Pulmonary Transit Time Can Be Accurately Quantified From Non‐Arterial Input Function Series in First‐Pass Cardiac Perfusion MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2207-2213, April 2026.
ABSTRACT Purpose Previous studies suggested that arterial‐input‐function (AIF) images are necessary to avoid signal saturation for pulmonary transit time (PTT) measurements. This study challenges that notion by investigating whether PTT can be accurately measured using blood pool signals from myocardial enhancement (non‐AIF) images during resting first‐

Safety of Vortioxetine in Patients With Depression: A Post‐Marketing Surveillance Study of Intracranial Hemorrhage in a Japanese Health Insurance Claims Database

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 1, March 2026.
This real‐world, retrospective cohort study showed that the incidence of intracranial hemorrhage was low in Japanese patients with depression prescribed vortioxetine, and comparable with that observed in patients prescribed selective serotonin reuptake inhibitors (SSRIs).
