Effect of single mannitol bolus in intracerebral hemorrhage
Bibliographic record
Abstract
Because of existing controversy about use of mannitol in intracerebral hemorrhage (ICH) this open exploratory trial with blinded outcome assessment of single mannitol bolus in ICH was undertaken. CT proven primary supratentorial ICH patients having midline shift of > or =3 mm were randomized into 20% mannitol (1.5 g/kg) and control groups. Clinical evaluation included Glasgow coma scale (GCS) score, Canadian Neurological scale (CNS) score, pupils, breathing, extensor posturing and contra-lateral pyramidal signs. On cranial MRI horizontal (HS), superior sagittal sinus to pontomesencephalic junction (SSS-PMJ) distance and edema hematoma complex were measured. Twelve patients each were in mannitol and control groups. The age, sex, GCS score, CNS score, pupillary asymmetry, contra-lateral pyramidal signs, HS and SSS-PMJ distance in mannitol and control groups did not differ significantly. Mannitol infusion resulted clinical improvement in five patients, which lasted for 30-60 min. HS and SSS-PMJ distance in mannitol and control groups did not change at 30 or 60 min from the baseline. The change in HS and SSS-PMJ distance were also not significantly different between the two groups both at 30 and 60 min. Mannitol led to transient clinical improvement in five patients without significant reduction in HS or SSS-PMJ distance at 30 and 60 min.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
