Idiopathic Infantile Arterial Calcification and Persistent Pulmonary Hypertension
Bibliographic record
Abstract
Idiopathic infantile arterial calcification is a rare and usually fatal disorder, which is characterized by widespread vaso-occlusive disease. Presentation is variable, but refractory hypertension is typical, with symptoms of cardiorespiratory failure. Some present in utero with evidence of fetal compromise, which may manifest as hydrops fetalis and premature delivery or stillbirth. Presentation otherwise is usually in the neonatal period with 85% of cases being fatal within the first 6 months. Coronary artery involvement is a poor prognostic feature. The pathophysiology of this disorder is well documented but the underlying etiology remains unknown. An autosomal recessive metabolic disorder is thought likely and this is supported in this case. Pulmonary hypertension has not previously been reported to be a primary feature of this disease. Here we describe such a case in which a newborn underwent extracorporeal membrane oxygenation, and during this time a diagnosis of idiopathic arterial calcification was made.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
