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

Artificial Organs, EarlyView.
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.

Elevated Serum Neurofilament Light Chain Is Associated With Systemic Inflammation in Very Preterm Infants

Acta Paediatrica, EarlyView.
ABSTRACT Aim Neurofilament light chain (NFL) and glial fibrillary acidic protein (GFAP) are known biomarkers of brain injury in adults, but their significance in very preterm (VPT) infants remains unclear. Given the strong link between inflammation, oxidative stress, and brain injury in this population, we investigated associations between NFL, GFAP ...

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

Pacing and Clinical Electrophysiology, EarlyView.
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 ...

Early exposure, enduring consequences: How do I manage Rh immunoglobulin prophylaxis after Rh‐mismatched transfusions in children?

Transfusion, EarlyView.
Abstract Background RhD mismatched transfusions in RhD negative women have the potential to impact future pregnancies through alloimmunization and development of hemolytic disease of the fetus and newborn (HDFN). As use of RhD positive emergency‐release blood products in pediatric trauma has increased, it has become clear that a significant ...

Association of red blood cell transfusions with periventricular leukomalacia in very preterm infants

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Red blood cell (RBC) transfusions have been associated with retinopathy of prematurity (ROP) and adverse long‐term neurodevelopmental outcomes in very preterm infants. Although lower transfusion thresholds reduce the incidence of ROP, they have not improved neurological outcome. Periventricular leukomalacia (PVL) is a

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Feasibility of superimposed supine cycling and lower body negative pressure as an effective means of prolonging exercise tolerance in individuals experiencing persisting post‐concussive symptoms: Preliminary results

Experimental Physiology, EarlyView.
Abstract To examine the feasibility, utility and safety of superimposed lower body negative pressure (LBNP) and tilt during supine cycling in individuals suffering from persisting post‐concussive symptoms (PPCS). Eleven individuals aged 17–31 (6 females/5 males) participated in two randomized separate visits, 1 week apart.

[The effect of nicergoline on the systemic and cerebral hemodynamics of patients with circulatory encephalopathy and an atherosclerotic lesion of the major cerebral arteries].

Likars'ka sprava, 1993
The Evans blue dilution method and ultrasound dopplerography were used to study the effect of nicergolin on the systemic and cerebral hemodynamics in 31 patients with dyscirculatory encephalopathy against the background of atherosclerotic lesions of the major head arteries.

Effects of the angle of head‐down tilt on dynamic cerebral autoregulation during combined exposure to cephalad fluid shift and mild hypercapnia

Experimental Physiology, EarlyView.
Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...
