Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability

, 2013
Although the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its ...

Arterial occlusion induces systemic changes in leucocyte composition. [PDF]

, 2011
Background Lack of tissue perfusion because of arterial occlusion can result in mortality and morbidity. In response to local tissue ischaemia, extravasation of leucocytes into the region at risk is initiated to facilitate matrix remodelling and ...

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

HOPE Kids 2: Phase 3, Randomized Trial of Voxelotor in Children With SCD and Conditional Cerebral Blood Flow Velocities

American Journal of Hematology, EarlyView.
ABSTRACT Children with SCD have elevated stroke risk, correlated with cerebral blood flow velocity (CBFV). HOPE Kids 2 was a phase 3, multicenter, double‐blind, placebo‐controlled trial evaluating the effect of voxelotor on CBFV. Participants aged 2 to < 15 years with SCD (HbSS/HbSβ0) and conditional CBFV (170 to < 200 cm/s) were randomized 1:1 to ...

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

1,2‐propanediol reformulation improves tribromoethanol safety and reveals pontine GABRA1 enrichment as a candidate mechanistic correlate of anesthesia

Animal Models and Experimental Medicine, EarlyView.
This study develops a reformulated tribromoethanol (TBE) anesthetic using 1,2‐propanediol as a solvent to overcome solvent‐related toxicity. The novel formulation demonstrates, cardiovascular stability, and survival in prolonged protocols. It provides potent, dose‐dependent anesthesia without strain or sex differences.
