Multimodality Imaging of Right-Sided (Tricuspid Valve) Papillary Fibroelastoma: Recognition of a Surgically Remediable Disease

Presentation of an increasingly recognized right-sided primary valve tumor of clinical importance: the tricuspid valve papillary fibroelastoma (PF). Early recognition and surgical intervention is emphasized for valvular PF, which carries a significant risk of morbidity and mortality. Newer imaging techniques, including CT and MRI, assist in localizing and differentiating PF from alternative cardiac pathology

Lower sleep variability associated with higher academic performance across the semester in college students

The present study examined associations between physical activity, sleep, and academic outcomes in undergraduate students (N = 52). More consistent sleep throughout the semester (lower sleep variability) was associated with higher homework grades. The interaction between sleep variability and sleep quantity was not significant suggesting that greater sleep overall did not buffer students from the negative effects of sleep variability on grades
