Difference in Cerebral Microembolization With Multielectrode Pentaspline or Variable‐Loop Circular PFA Systems

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is a largely nonthermal modality with myocardial selectivity and collateral damage sparing. Cerebrovascular safety remains an important consideration as catheter design and pulse parameters may influence embolic risk.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Transcranial Doppler ultrasonography to evaluate cerebral hemodynamic changes in neurocysticercosis

Arquivos de Neuro-Psiquiatria
Background Arteritis is a complication of neurocysticercosis (NCC), which is not well known and could trigger strokes. The transcranial Doppler ultrasound (TCD) is a noninvasive method for detecting, staging, and monitoring cerebrovascular ...

The effect of combined treatment with transcranial direct current stimulation on cerebral blood flow in patients with cerebral palsy

Zaporožskij Medicinskij Žurnal, 2017
There is a close link between the activity of the brain and cerebral blood supply. Transcranial direct current stimulation (tDCS) modulates the activity of the cerebral cortex and thus affects the cerebral blood flow.

The Role of Neighborhoods in the Receipt of Transcranial Doppler Screening among Children with Sickle Cell Disease [PDF]

, 2015
Summary: Although transcranial Doppler (TCD) screening assesses the need for stroke prevention efforts among children with sickle cell disease (SCD), screening rates remain low across many parts of the United States.

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.

Assessment of the risk of stroke in children with sickle cell anemia using transcranial doppler ultrasound with imaging in Northwestern Nigeria

Nigerian Journal of Paediatrics, 2023
Background: Stroke is a major cause of morbidity and mortality affecting about 10% of patients with sickle cell anemia (SCA). Transcranial Doppler (TCD) ultrasonography helps to identify children with SCA who are at an increased risk for stroke.

Cerebral blood flow autoregulation is impaired in schizophrenia [PDF]

, 2017
Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear.

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 ...
