Respiratory morbidity in the first year of life of preterm infants discharged from a neonatal intensive care unit
Bibliographic record
Abstract
OBJECTIVE: The objective of this study was to verify the incidence of respiratory morbidity in the first year of life in very low birth weight preterm infants and also to compare the presence of respiratory morbidity in the first year of life according to neonatal risk factors. METHODS: This is a prospective cohort study. We studied preterm newborn infants weighing less than 1,500 g and with gestational age less than 34 weeks who were born between 1998 and 2000. During the first year of life, the infants received monthly medical follow-up and during each visit we evaluated the patients considering the presence of obstructive airway syndrome and/or pneumonia and/or hospital admission due to respiratory conditions. The incidence rate of respiratory morbidity in the first year of life was measured. Chi-squared test was used to compare proportions. RESULTS: The cohort was constituted of 97 preterm infants with mean birthweight of 1,113 g and mean gestational age of 28 weeks. The incidence rates of obstructive airway syndrome, pneumonia and hospital admission were 28, 36 and 26%, respectively. The incidence rate of respiratory morbidity was 53%. There was a significant difference between the incidence rates of respiratory morbidity among infants who had a prolonged use of oxygen (83%) and those who did not (43%). CONCLUSION: More than 50% of the infants presented respiratory morbidity in the first year of life and there was a high percentage of pneumonia and hospitalization due to respiratory conditions. Infants who had a prolonged use of oxygen presenting with higher respiratory morbidity incidence rate than infants who did not use oxygen for a long period.

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.
