Bronchiolitis and Pneumonia Requiring Hospitalization in Young First Nations Children in Northern Ontario, Canada
Bibliographic record
Abstract
BACKGROUND: High rates of lower respiratory tract infection (LRTI), including bronchiolitis and pneumonia, have been reported in Inuit infants living in arctic Canada. We examined rates of LRTI in First Nations Canadian infants living in the Sioux Lookout Zone, in Northern Ontario. METHODS: A retrospective review of hospital admissions for LRTI during a 5-year period, in patients <1 year of age was carried out at the Sioux Lookout Meno Ya Win Health Centre, an acute-care hospital that provides secondary care to 31 mainly isolated communities and the town of Sioux Lookout. Admission rates were compared with those in the province of Ontario, as a whole. RESULTS: One-hundred and seventeen subjects were identified. The annualized rate of admission for nonbacterial LRTI was 44 per 1000 infants <1 year of age per year. This rate was significantly higher than for the whole province (P = 0.011). Admission rates also varied significantly between communities (P < 0.001).Thirteen percent of subjects required transfer to a tertiary care center. A virus was identified in 55% (36/65) of subjects tested for respiratory viruses, and respiratory syncytial virus and parainfluenza virus were identified most often. Of patients who had a blood culture performed, bacteria were found in 10% (6/59) of subjects. Many patients had radiographic evidence of consolidation, consistent with pneumonia. CONCLUSIONS: Rates of LRTI are significantly elevated in First Nations infants living in the Sioux Lookout Zone. Varying rates between communities suggest that environmental factors may be contributing to rates of LRTI in this population.

How this classification was reachedexpand
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.
