Abstract

fetched live from OpenAlex

AIMS: We investigated the role of metabolic alterations in the development of a maladaptive right ventricular (RV) response in pulmonary arterial hypertension (PAH), which has not previously been undertaken. This study evaluated relationships between glucose and fatty acid metabolism obtained using PET with invasive pulmonary haemodynamics, RV measurements, and RV function to gain insight into the mechanism of RV maladaptation. METHODS AND RESULTS: (r = -0.62, P = 0.019). CONCLUSION: Increased pulmonary arterial pressures are associated with increases in the ratio of FDG/FTHA uptake in the RV. Inverse correlation between the uptake of the metabolic tracers and RV function may reflect a shift towards increased fatty acid oxidation and glycolysis associated with RV failure in maladaptive remodelling.

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.
