Objectives: Diagnostic shifts in first episode psychosis (FEP) are not uncommon. Many studies examining diagnostic stability use structured diagnostic interviews. Less is known about the stability of FEP diagnoses made clinically.
Methods: We conducted a retrospective chart review of patients enrolled in a transdiagnostic FEP clinic. For the 96 patients followed clinically at least 2 years, we compared diagnoses at intake and 24 months.
Results: Diagnostic stability was high for bipolar disorder (89%), schizoaffective disorder (89%), and schizophrenia (82%). Psychosis not otherwise specified (13%) was more unstable, with limited baseline differences that would enable clinicians to predict who would convert to a primary psychotic vs affective psychotic disorder.
Conclusions: Our real-world clinical sample shows that FEP diagnoses, with the exception of unspecified psychosis, are diagnostically stable, even without structured diagnostic interviews.

The relationship between vitamin C nutritional status and inflammation has garnered increasing attention, but studies in younger populations are limited. This study aimed to investigate the association between serum vitamin C and high-sensitivity C-reactive protein (hs-CRP) levels in children and adolescents. A cross-sectional analysis was conducted using data from the National Health and Nutrition Examination Survey (NHANES).

The integration of Electric Vehicles (EVs) into power grids introduces several critical challenges, such as limited scalability, inefficiencies in real-time demand management, and significant data privacy and security vulnerabilities within centralized architectures. Furthermore, the increasing demand for decentralized systems necessitates robust solutions to handle the growing volume of EVs while ensuring grid stability and optimizing energy utilization. To address these challenges, this paper presents the Demand Response and Load Balancing using Artificial intelligence (DR-LB-AI) framework.

For over a century African swine fever (ASF) has been causing outbreaks leading to devastating losses for the swine industry. The current pandemic of ASF has shown no signs of stopping and continues to spread causing outbreaks in additional countries. Currently control relies mostly on culling infected farms, and strict biosecurity procedures.

CD73, an ectoenzyme responsible for adenosine production, is often elevated in immuno-suppressive tumor environments. Inhibition of CD73 activity holds great promise as a therapeutic strategy for CD73-expressing cancers. In this study, we have developed a therapeutic anti-human CD73 antibody cocktail, HB0045.

Maintenance of protein homeostasis is necessary for cell viability and depends on a complex network of chaperones and co-chaperones, including the heat-shock protein 70 (Hsp70) system. In human mitochondria, mitochondrial Hsp70 (mortalin) and the nucleotide exchange factor (GrpEL1) work synergistically to stabilize proteins, assemble protein complexes, and facilitate protein import. However, our understanding of the molecular mechanisms guiding these processes is hampered by limited structural information.
