Risk Factors and Outcomes for Respiratory Syncytial Virus–related Infections in Immunocompromised Children
Bibliographic record
Abstract
BACKGROUND: Respiratory syncytial virus (RSV) is associated with significant morbidity and mortality in immunocompromised children. Data on the risk factors for acquisition and outcomes from RSV infections in this population are limited. METHODS: This cohort study (2006 to 2011) included RSV-positive immunocompromised pediatric inpatients. Nasopharyngeal swabs were tested for RSV by direct immunofluorescence. Purposeful multiple regression was used to assess risk factors associated with community-acquired RSV (CA-RSV) infections and their outcomes compared with nosocomial (N-RSV) infections. Means and medians were compared using Student's t test and a nonparametric test, respectively. Proportions were compared using χ(2) or Fisher's exact test, as appropriate. RESULTS: There were 117 RSV-positive patients of whom 42 (35.9%) presented with (N-RSV) infection. Overall, more than a third presented with lower respiratory tract infections, which resulted in a 28% admission rate to the intensive care unit and a mortality rate of 5%; the latter solely among patients with community-acquired infection. Subjects with CA-RSV presented with more advanced clinical evidence of lower tract disease with respiratory distress (eg, intercostal recession; odds ratio 2.5; 95% confidence interval: 1.1-5.6; P = 0.03) compared with those with N-RSV. Subjects with CA-RSV infections were less likely to have a prolonged hospital admission (odds ratio 0.7; 95% confidence interval: 0.5-0.8; P < 0.0001) relative to those with N-RSV infections. CONCLUSIONS: RSV-related infections in immunocompromised children may result in poor outcomes, including mortality. Differences in mortality rates among those with CA-RSV compared with N-RSV warrant further study, with enhanced opportunities for prevention and early detection of infection.

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.
