Unilateral Agenesis of Pulmonary Artery
Bibliographic record
Abstract
Isolated unilateral agenesis of pulmonary artery was first defined at 1868. Although the exact prevalance is unknown, in a study it is estimated as 1/200,000. Congenital unilateral agenesis of pulmonary artery is a rare anomaly which is frequently associated with other congenital cardiovascular anomalies such as tetralogy of Fallot or septal defects. In 37% of cases left pulmonary artery is absent while in 63% the right one is absent. Nearly 30% of patients are asymptomatic. When symptomatic, patients may experience chest pain, pleural effusion, recurrent pulmonary infections, dyspnea or limited exertion or hemoptysis. Several methods are used in diagnosis such as computerized tomography, bronchography, perfusion scintigraphy, echocardiography and cardiac catheterisation. Massive hemoptysis, cardiac insufficiency, bronchectasis and necrotizing bronchopnemonia may be included among the complications. The following case report presents a patient who was not diagnosed until adult ages. doi: http://dx.doi.org/10.4021/jmc1428w

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.
