Role of sleep and white matter in the link between screen time and depression in childhood and early adolescence

JAMA Network
Peer-Reviewed Publication

About The Study: The results of this study show that more screen time in late childhood was associated with more depressive symptoms, potentially due to shorter sleep and worse white matter organization during early adolescence. These findings emphasize the importance of promoting healthy habits and balancing screen time with adequate sleep.

Teen depression? Study finds clues in screen use and sleep quality

University of Pittsburgh
Peer-Reviewed Publication

New research suggests that that association between longer screen use and adolescent depression is driven by shorter sleep and worse organization of the brain white matter.

Alzheimer’s protective mutation works by taming inflammation in the brain

Weill Cornell Medicine
Peer-Reviewed Publication

A rare gene mutation that delays Alzheimer’s disease does so by damping inflammatory signaling in brain-resident immune cells, according to a preclinical study led by investigators at Weill Cornell Medicine. The finding adds to growing evidence that brain inflammation is a major driver of neurodegenerative disorders such as Alzheimer’s—and that it may be a key therapeutic target for these disorders.

SNMMI image of the year: New immuno-pet tracer superior to FDG PET in predicting PD-L1 expression in head and neck cancer

Society of Nuclear Medicine and Molecular Imaging
Peer-Reviewed Publication

A first-in-class peptide-based PET tracer, ¹⁸F-AlF-NOTA-PCP2, can effectively measure PD-L1 expression in patients with head and neck cancers, outperforming the conventional tracer ¹⁸F-FDG. ¹⁸F-AlF-NOTA-PCP2 uptake strongly correlated with PD-L1 levels,highlighting the tracer’s potential to improve patient stratification and guide personalized treatment strategies. This research was presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2025 Annual Meeting, and the grouping of images comparing ¹⁸F-AlF-NOTA-PCP2 and ¹⁸F-FDG uptake has been selected as the 2025 SNMMI Henry N. Wagner, Jr., Image of the Year.
