Glial Fibrillary Acidic Protein Astrocytopathy Based on a Two‐Center Chinese Cohort Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glial fibrillary acidic protein astrocytopathy (GFAP‐A) is a recently defined nosological form belonging to the class of autoimmune inflammatory disorders affecting the central nervous system (CNS). Here, we report the clinical and MRI characteristics, treatment, and prognosis of a GFAP‐A cohort from two centers in China.

Understanding Mechanisms of Whole Brain and Regional Grey Matter Atrophy in Children With MOGAD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate the mechanisms driving whole brain and regional grey matter (GM) volume changes along with their clinical correlates in paediatric myelin oligodendrocyte glycoprotein antibody (MOG‐Ab)–associated disease (MOGAD). Methods One‐hundred‐nine paediatric MOGAD patients from two UK centres underwent MRI at attack nadir and ...

The Variation in the Diastolic Period with Interventricular Septal Displacement and Its Relation to the Right Ventricular Function in Pulmonary Hypertension: A Preliminary Cardiac Magnetic Resonance Study

open access: yesDiagnostics, 2022
Background: Pulmonary hypertension (PH) is known to alter the biventricular shape and temporal phases of the cardiac cycle. The presence of interventricular septal (IVS) displacement has been associated with the severity of PH.

Preservation of ventricular function by treatment of ventricular fibrillation with phenylephrine

open access: yesJournal of the American College of Cardiology, 1990
Epinephrine promotes resuscitation from ventricular fibrillation because of its peripheral vasoconstrictive effects. However, the beta-adrenergic effects of epinephrine may be detrimental because of the stimulation of myocardial oxygen demand. To test whether functional recovery from fibrillation in hearts treated with a selective alpha-adrenergic ...

Discovery and Treatment of Action Potential‐Independent Myotonia in Hyperkalemic Periodic Paralysis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hyperkalemic periodic paralysis (hyperKPP) is characterized by attacks of transient weakness. A subset of hyperKPP patients suffers from transient involuntary contraction of muscle (myotonia). The goal of this study was to determine mechanisms causing myotonia in hyperKPP.

Efeitos da angiotensina-I e isquemia na recuperação funcional em corações isolados Effects of angiotensin-I and ischemia on functional recovery in isolated hearts

open access: yesArquivos Brasileiros de Cardiologia, 2011
FUNDAMENTO: A ressuscitação de parada cardíaca pode apresentar disfunção miocárdica determinada pelo tempo da isquemia, e a inibição da enzima conversora de angiotensina (ECA) pode reduzir a disfunção cardíaca durante a reperfusão.

Evaluation of myocardial contraction fraction in transcatheter aortic valve replacement

open access: yesHeart Vessels and Transplantation, 2023
Objective: Myocardial contraction fraction (MCF), a costless, easy-to-perform echocardiographic measure, which estimates cardiac function through the volumetric measurement of myocardial shortening, may be a useful prognostic indicator in patients ...
