Cognitive function in pediatric-onset relapsing myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).

Introduction: Myelin oligodendrocyte glycoprotein antibodies are identified in approximately 30-50% of youth with pediatric-onset acquired demyelinating syndromes. Little is known about the cognitive sequelae of relapsing myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) with onset in childhood or adolescence.Overall, adults had 41% more risk than children to relapse over the whole disease course Overall, adults had 41% more risk than children to relapse over the whole disease course OBJECTIVE: To compare cognitive performance in participants with pediatric-onset relapsing MOGAD, pediatric-onset multiple sclerosis (POMS), and age-matched healthy controls.

Memory, processing of emotional stimuli, and volume of limbic structures in pediatric-onset multiple sclerosis.

Objective: The limbic system is involved in memory and in processing of emotional stimuli. We measured volume of the hippocampus, amygdala, and thalamus, and assessed their relative contribution to episodic memory and emotion identification in POMS.

Method: Sixty-five POMS participants (M = 18.

Examining cognitive speed and accuracy dysfunction in youth and young adults with pediatric-onset multiple sclerosis using a computerized neurocognitive battery.

Objective: We evaluated performance on the Penn Computerized Neurocognitive Battery (PCNB), a tool assessing accuracy and response time across four cognitive domains, alongside the Symbol Digit Modalities Test (SDMT), a measure of processing speed commonly used in MS. We determined whether performance decrements are more likely to be detected on measures of accuracy versus response time in pediatric-onset multiple sclerosis (POMS).

Methods: Performance on the SDMT, accuracy on PCNB tests belonging to four domains (executive function, episodic memory, complex cognition, social cognition), and response time on the PCNB were compared for 65 POMS patients (age range: 8-29 years) and 76 healthy controls (HCs) by ANCOVA.

Major difference in clinical outcome and replication of a H3N1 avian influenza strain in young pullets and adult layers.

In this study, we investigated the pathogenicity, replication and tropism of the low pathogenic avian influenza (LPAI) strain A/chicken/Belgium/460/2019(H3N1) in adult SPF layers and young SPF males. The inoculated hens showed 58% mortality and a 100% drop in egg production in the second week post inoculation. The high viral loads in the cloacal samples coincided with the period of the positive immunohistochemistry of the oviduct, acute peritonitis and time of mortality, suggesting that the replication of H3N1 in the oviduct was a major component of the onset of clinical disease and increased level of excretion of the virus.

Impact of a Supervised Twelve-Week Combined Physical Training Program in Heart Failure Patients: A Randomized Trial.

Purpose: The aim of this study was to compare the effects of supervised combined physical training and unsupervised physician-prescribed regular exercise on the functional capacity and quality of life of heart failure patients.

Methods: This is a longitudinal prospective study composed of 28 consecutive heart failure with reduced ejection fraction patients randomly divided into two age- and gender-matched groups: trained group ( = 17) and nontrained group ( = 11). All patients were submitted to clinical evaluation, transthoracic echocardiography, the Cooper walk test, and a Quality of Life questionnaire before and after a 12-week study protocol.
