Enzymopenic Congenital Methemoglobinemia in Children of the Republic of Sakha (Yakutia)
Bibliographic record
Abstract
Type I congenital methemoglobinemia is an autosomal recessive disorder. A high frequency of congenital methemoglobinemia has been reported among Native Americans inhabiting the Yukon-Kuskokwim Delta. Other rare cases of congenital methemoglobinemia of types I and II have been reported in Japan and other countries. In Russia-namely, in Yakutia-a high frequency of type I congenital methemoglobinemia has been reported. In 2009, the Consultation Polyclinic of the Pediatric Center in Yakutsk city established a registry of children with congenital methemoglobinemia. In total, 43 patients were registered between 2005 and 2009. The median methemoglobin level was 13.5% (ranging between 4.2% and 33.9%) and physical examination revealed cyanosis of the skin and mucus membranes. There were significant positive relationships between percentage of methemoglobin and erythrocyte count, hemoglobin concentration, and hematocrit among male patients, consistent with an upregulation of the hypoxic response. The prevalence per 100,000 children ranged from 12.7 to 47.0 in 3 geographic regions of Yakutia. Further research is needed to clarify the clinical consequences of congenital methemoglobinemia in the children of Yakutia and the reasons for the high variability in the prevalence of the condition.

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.
