The parents' journey: continuing a pregnancy after a diagnosis of Patau's syndrome
Bibliographic record
Abstract
<h3>Abstract</h3> <h3>Objective</h3> To determine if screening of infants for anemia at 9 months in the Cree region of Quebec should continue, by comparing the prevalence of anemia in the initial years of screening (1995 to 2000) with prevalence data from infants screened between 2002 and 2007. <h3>Design</h3> Comparison of anemia prevalence from 2 cross-sectional surveys. Nonoverlapping 95% CIs were used to determine if results were significantly different. <h3>Setting</h3> Nine Quebec Cree communities. <h3>Participants</h3> Infants screened for anemia between 1995 and 2000 (n = 716) or 2002 and 2007 (n = 1325). <h3>Main outcome measures</h3> Anemia was diagnosed based on hemoglobin concentration. An erythrocyte mean cell volume of less than 71 fL was used as a proxy for iron deficiency. <h3>Results</h3> Hemoglobin concentration among infants screened from 2002 to 2007 was, on average, 7 g/L greater than among infants screened from 1995 to 2000 (mean [standard deviation] 121 [11] g/L vs 114 [11] g/L). The prevalence of anemia (hemoglobin < 110 g/L) from 1995 to 2000 was 31.7% (95% CI 28.3% to 35.1%), but from 2002 to 2007 it was significantly lower at 12.5% (95% CI 10.7% to 14.2%). Using a hemoglobin concentration more specific to iron deficiency anemia (IDA) (hemoglobin < 100 g/L), from 1995 to 2000 7.5% (95% CI 5.6% to 9.4%) of infants had IDA, whereas from 2002 to 2007 only 2.0% (95% CI 1.2% to 2.8%) had IDA. The prevalence of iron deficiency based on mean cell volume declined from 18.3% (95% CI 15.5% to 21.1%) from 1995 to 2000 to 4.2% (95% CI 3.1% to 5.3%) from 2002 to 2007. <h3>Conclusion</h3> The 12.5% prevalence of anemia (hemoglobin < 110 g/L) among Cree infants from 2002 to 2007 was much lower than the prevalence from 1995 to 2000 but somewhat higher than among nonaboriginal infants (8.0%). The low anemia prevalence among Quebec Cree infants after 2002 suggests that replacing universal screening with targeted screening of higher-risk infants needs to be considered following studies to identify risk factors for anemia.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
