Using Latent Patient-Centered Fear Extinction Profiles To Guide Treatment In Pediatric Ocd, Katherine M Ingram, Eric A Storch, Daniel A Geller, Brent J Small, Sabine Wilhelm, Joseph F Mcguire

Faculty, Staff and Students Publications

Background: While exposure with response prevention (ERP) is the frontline treatment for pediatric obsessive-compulsive disorder (OCD), not all patients benefit. Impairments in extinction learning are implicated in pediatric OCD's etiology and treatment, with impaired pre-treatment extinction learning associated with worse ERP outcomes. However, available methods for assessing patients' difficulties with fear extinction are costly and underdeveloped. In response, we used person-centered profiles to characterize latent fear extinction patterns among youth with OCD, and investigated the degree to which scores on common rating scales correspond to profile membership.

Methods: Youth with OCD (n=98) completed a diagnostic clinical battery followed by a …

Lactate-derived N-lactoyl-phenylalanine (Lac-Phe) was recently identified as an lactate-derived circulating metabolite that reduces feeding and obesity, but mechanisms that underlie the metabolic benefits of Lac-Phe remain unknown. Here we demonstrated that Lac-Phe directly inhibits hypothalamic neurons that express Agouti-related protein (AgRP), resulting in an indirect activation of anorexigenic neurons in the paraventricular nucleus of the hypothalamus (PVH). We also found that both AgRP inhibition and PVH activation are required to mediate Lac-Phe-induced hypophagia. Further, we show that Lac-Phe inhibits AgRP neurons via activating the ATP-sensitive potassium (KATP) channel, and inhibition of the KATP channel blunts effects of Lac-Phe to suppress …

Succinate Dehydrogenase B (Sdhb) Overexpression With Enzymatic Dysfunction Defines A Distinct Subtype Of Undifferentiated Pleomorphic Sarcoma, Miguel Esperança-Martins, Brian A Van Tine, Alliny C S Bastos, Et Al.

2020-Current year OA Pubs

UNLABELLED: Undifferentiated pleomorphic sarcoma (UPS) remains one of the most clinically aggressive and poorly characterized soft-tissue sarcoma subtypes. To uncover distinctive molecular traits for UPS, a multiomics analysis of UPS compared with leiomyosarcoma (LMS) and liposarcoma (LPS) was performed. Transcriptomic profiling revealed that UPS exhibits overexpression of genes encoding succinate dehydrogenase (SDH) subunits, particularly SDHB, SDHC, and SDHD, distinguishing it from LMS and dedifferentiated LPS. This finding was validated using The Cancer Genome Atlas Sarcoma dataset. High SDHB expression in UPS was significantly associated with shorter overall survival, shorter recurrence-free survival, and shorter overall survival from the date of first …
