Abstract

fetched live from OpenAlex

Objective: To investigate morphofunctional changes of the neuro-glial-vascular interface in children with metabolic intoxications, particularly in acetonemic syndrome and hyperammonemia. Materials and methods: A systematic literature review with elements of narrative analysis was conducted following PRISMA guidelines. Literature search was performed in PubMed/MEDLINE, Web of Science Core Collection, Scopus, and Cochrane Library for the period 1990-2024. Included studies involved children from birth to 18 years and investigated neurotoxic effects of acetonemic syndrome and hyperammonemia. Study quality was assessed using Newcastle-Ottawa Scale, AMSTAR-2, and SYRCLE tools. Results: Key morphofunctional disorders of the neuro-glial-vascular interface were identified: cytotoxic astrocytic swelling due to glutamine accumulation during ammonia detoxification; blood-brain barrier disruption with decreased expression of tight junction proteins (claudin-5, occludin, ZO-1); impaired energy metabolism due to glycolysis inhibition and mitochondrial dysfunction; excitotoxicity resulting from glutamate-glutamine cycle disruption; microglial activation with increased expression of CD68, Iba1, MHC II, and pro-inflammatory cytokine secretion. Conclusions: Morphofunctional changes of the neuro-glial-vascular interface with acetonemic syndrome and hyperammonemia are characterized by complex disruptions of blood-brain barrier (BBB) structure and function, energy metabolism, neurotransmitter balance, and neuroinflammatory processes. A personalized approach to diagnosis and treatment using biomarkers of BBB damage and neuroinflammation is necessary.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
