Purpose: We describe trends in psilocybin exposures among adolescents and young adults as reported to US poison centers over the past decade.
Methods: We queried the National Poison Data System for cases involving psilocybin during January 1, 2013-December 31, 2022. Persons aged 13-25 years were included. We examined exposures to psilocybin by demographics, clinical effects, level of care, and medical outcome.
Results: During the 10-year study period, 4,055 psilocybin-involved exposures were reported among adolescents and young adults, 2,667 (65.8%) being single substance exposures. Most single substance cases received medical attention (adolescents: 75.3% [n = 1,176], young adults: 72.1% [n = 797]). We did not find significant change in the number of cases during 2013-2018. Cases started increasing in 2019. In 2022, cases more than tripled among adolescents and more than doubled among young adults, compared to 2018 (p < .0001).
Discussion: Continued national surveillance is critical to determine the impact of psilocybin exposures on youth as it becomes increasingly available.

Purpose: Precision medicine plays an important role in the treatment of patients with advanced melanoma. Despite its high incidence in White patients, advanced melanoma is rare in Asian countries, hampering prospective clinical trials targeting the Asian population. This retrospective study aimed to elucidate the real-world molecular diagnoses and outcomes of Japanese patients with melanoma using comprehensive genome profiling (CGP).

Background And Objectives: Antibodies to proteolipid protein-1 (PLP1-IgG), a major central myelin protein also expressed in the peripheral nervous system (PNS) as the isoform DM20, have been previously identified mostly in patients with multiple sclerosis (MS), with unclear clinical implications. However, most studies relied on nonconformational immunoassays and included few patients with non-MS CNS autoimmune demyelinating disorders (ADDs). We aimed to investigate conformational PLP1-IgG in the whole ADD spectrum.

Background And Objectives: While it is well characterized in adults, little is known about the clinical features of neurofascin 155-IgG4 autoimmune nodopathy (NF155-IgG4 AN) in the pediatric population. In this study, we aimed to describe the clinical features and treatment outcomes in children diagnosed with neurofascin 155-IgG4 autoimmune nodopathy (NF155-IgG4 AN).
Methods: Pediatric and adult patients with NF155-IgG4 AN were identified retrospectively through the Mayo Clinic Neuroimmunology Laboratory database.

Extracellular matrix (ECM) derived from mesenchymal stem cells regulates antioxidant properties and bone metabolism by providing a favorable extracellular microenvironment. However, its functional role and molecular mechanism in mitochondrial function regulation and aged bone regeneration remain insufficiently elucidated. This proteomic analysis has revealed a greater abundance of proteins supporting mitochondrial function in the young ECM (Y-ECM) secreted by young bone marrow-derived mesenchymal stem cells (BMMSCs) compared to the aged ECM (A-ECM).
