Cognitive function in patients with stable coronary heart disease: Related cerebrovascular and cardiovascular responses. [PDF]

PLoS ONE, 2017
Chronic exercise has been shown to prevent or slow age-related decline in cognitive functions in otherwise healthy, asymptomatic individuals. We sought to assess cognitive function in a stable coronary heart disease (CHD) sample and its relationship to ...

Ventilation onset prior to umbilical cord clamping (physiological-based cord clamping) improves systemic and cerebral oxygenation in preterm lambs. [PDF]

PLoS ONE, 2015
BACKGROUND:As measurement of arterial oxygen saturation (SpO2) is common in the delivery room, target SpO2 ranges allow clinicians to titrate oxygen therapy for preterm infants in order to achieve saturation levels similar to those seen in normal term ...

Sedation agents differentially modulate cortical and subcortical blood oxygenation: evidence from ultra-high field MRI at 17.2 T. [PDF]

PLoS ONE, 2014
Sedation agents affect brain hemodynamic and metabolism leading to specific modifications of the cerebral blood oxygenation level. We previously demonstrated that ultra-high field (UHF) MRI detects changes in cortical blood oxygenation following the ...

Cerebral Oximetry in Syncope and Syndromes of Orthostatic Intolerance

Frontiers in Cardiovascular Medicine, 2019
Cerebral autoregulation is crucial for maintaining cerebral blood flow and perfusion. In recent years, the importance of cerebral oxygenation in syncope and orthostatic intolerance (OI) has received increased attention. Cerebral tissue oxygenation can be

Cerebral oxygenation is highly sensitive to blood pressure variability in sick preterm infants. [PDF]

PLoS ONE, 2012
OBJECTIVES: The significance of blood pressure variability (BPV) for cerebral oxygenation in extremely preterm infants has not been explored, though BPV may well be associated with end organ injury.

Epinephrine’s effects on cerebrovascular and systemic hemodynamics during cardiopulmonary resuscitation

Critical Care, 2020
Background Despite controversies, epinephrine remains a mainstay of cardiopulmonary resuscitation (CPR). Recent animal studies have suggested that epinephrine may decrease cerebral blood flow (CBF) and cerebral oxygenation, possibly potentiating ...

Clinical Application of Near-Infrared Spectroscopy in Neonates [PDF]

Neonatal Medicine, 2019
The incidence of cerebral palsy has not decreased despite advances in neonatal care. Preterm infants are at a high risk of cerebral palsy. Moreover, preterm infants might experience permanent neurological sequelae due to injury in the preterm brain ...

Sleep apnea syndrome caused lowering of cerebral oxygenation in a hemodialysis patient: a case report and literature review

Renal Replacement Therapy, 2018
Background Sleep apnea syndrome (SAS) is a sleep disturbance, which is frequently comorbid in dialysis patients. SAS induces hypoxia, and therefore, systemic and cerebral oxygenation would be low.

Cortical hypoperfusion and reduced cerebral metabolic rate of oxygen in the arcAβ mouse model of Alzheimer’s disease

Photoacoustics, 2018
The effect of cerebral amyloidosis on cerebral hemodynamics was investigated with photoacoustic tomography (PAT) and magnetic resonance imaging (MRI). First, the sensitivity and robustness of PAT for deriving metrics of vascular and tissue oxygenation in
