Abstract

fetched live from OpenAlex

BACKGROUND: Although virus-induced wheezing is common in preschool-age children, optimal management remains elusive. We examined the efficacy and safety of preemptive treatment with high-dose fluticasone in reducing the severity of recurrent virus-induced wheezing in children. METHODS: We randomly assigned 129 children who were 1 to 6 years of age to receive 750 microg of fluticasone propionate (ex-valve [manufacturer-measured] dose) or placebo twice daily, beginning at the onset of an upper respiratory tract infection and continuing for a maximum of 10 days, over a period of 6 to 12 months. The primary outcome was rescue oral corticosteroid use. Secondary outcomes included symptoms, use of beta(2)-agonists, acute care visits, hospitalizations, discontinuation of the study drug, change in growth and bone mineral density, basal cortisol level, and adverse events. RESULTS: Over a median period of 40 weeks, 8% of upper respiratory tract infections in the fluticasone group led to treatment with rescue systemic corticosteroids, as compared with 18% in the placebo group (odds ratio, 0.49; 95% confidence interval [CI], 0.30 to 0.83). Children who were treated with fluticasone, as compared with those who were given placebo, had smaller mean (+/-SD) gains from baseline in height (6.23+/-2.62 cm [unadjusted value]; z score, -0.19 +/-0.42 vs. 6.56+/-2.90 cm [unadjusted value]; z score, 0.00+/-0.48; difference between groups in z score from baseline to end point, -0.24 [95% CI, -0.40 to -0.08]) and in weight (1.53+/-1.17 kg [unadjusted value]; z score, -0.15+/-0.48 vs. 2.17+/-1.79 kg [unadjusted value]; z score, 0.11+/-0.43; difference between groups in z score from baseline to end point, -0.26 [95% CI, -0.41 to -0.09]). There were no significant differences between the groups in basal cortisol level, bone mineral density, or adverse events. CONCLUSIONS: In preschool-age children with moderate-to-severe virus-induced wheezing, preemptive treatment with high-dose fluticasone as compared with placebo reduced the use of rescue oral corticosteroids. Treatment with fluticasone was associated with a smaller gain in height and weight. Given the potential for overuse, this preventive approach should not be adopted in clinical practice until long-term adverse effects are clarified. (ClinicalTrials.gov number, NCT00238927.)

Not 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.
