Short-Term Outcomes After Multisystem Inflammatory Syndrome in Children Treatment.

This is a retrospective chart review of 20 patients treated with a consensus-driven treatment algorithm in multisystem inflammatory syndrome in children patients across a wide clinical spectrum. Their treatments and clinical status are described as well as their favorable return to functional baseline by 30 days post presentation.

Hydroxychloroquine and tocilizumab therapy in COVID-19 patients-An observational study.

Hydroxychloroquine has been touted as a potential COVID-19 treatment. Tocilizumab, an inhibitor of IL-6, has also been proposed as a treatment of critically ill patients. In this retrospective observational cohort study drawn from electronic health records we sought to describe the association between mortality and hydroxychloroquine or tocilizumab therapy among hospitalized COVID-19 patients.

Subacute Aerococcus urinae Infective Endocarditis With Mycotic Aneurysms in a Pediatric Patient: Case Report and Literature Review.

Aerococcus urinae has been found to cause urinary tract infection in elderly patients and has been reported as a rare cause of infective endocarditis associated with significant morbidity and death in adults. However, information regarding its occurrence in children is lacking. We report here the case of a pediatric patient with subacute A urinae infective endocarditis with mycotic aneurysms.

CD8+ cell lines isolated from HIV-1-infected children have potent soluble HIV-1 inhibitory activity that differs from beta-chemokines.

CD8+ cells from human immunodeficiency virus type 1 (HIV-1) infected individuals have been shown to suppress HIV-1 replication both through a major histocompatibility complex (MHC)-restricted cytolytic pathway as well as through a noncytolytic pathway mediated through soluble factors. To characterize this soluble activity and its potential role in disease progression further, we studied the HIV-1 inhibition by supernatants derived from herpesvirus saimiri-transformed CD8+ cells isolated from infected children. Three of the six CD8+ cell lines derived had a phenotype consistent with an unusual natural killer (NK) cells phenotype with low CD3, high CD56, and low CD16.

Perception of acoustic correlates of major phrasal units by young infants.

How might young learners parse speech into linguistically relevant units? Sensitivity to prosodic markers of these segments is one possibility. Seven experiments examined infants' sensitivity to acoustic correlates of phrasal units in English. The results suggest that: (a) 9 month olds, but not 6 month olds, are attuned to cues that differentially mark speech that is artificially segmented at linguistically COINCIDENT as opposed to NONCOINCIDENT boundaries (Experiments 1 and 2); (b) the pattern holds across both subject phrases and predicate phrases and across samples of both Child- and Adult-directed speech (Experiments 3, 4, and 7); and (c) both 9 month olds and adults show the sensitivity even when most phonetic information is removed by low-pass filtering (Experiments 5 and (6).
