Sleep‐disordered breathing, respiratory patterns during wakefulness and functional capacity in pediatric patients with rapid‐onset obesity with hypothalamic dysfunction, hypoventilation and autonomic dysregulation syndrome
Bibliographic record
Abstract
OBJECTIVE: To characterize the clinical presentation of sleep-disordered breathing and respiratory patterns at rest and during a 6-min walk test (6MWT) in children with rapid-onset obesity, hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) syndrome. METHODS: Retrospective study of children with ROHHAD who had a diagnostic baseline polysomnography, daytime cardiorespiratory monitoring at rest and a 6MWT. Polysomnography data were also compared with body mass index-, age-, and sex-matched controls. RESULTS: Of the eight children with ROHHAD, all eight (100%) had obstructive sleep apnea (OSA) and 2/8 (25%) had nocturnal hypoventilation (NH) on their baseline polysomnography. Comparing the ROHHAD group to the control group, there were no significant differences in the median (interquartile range [IQR]) obstructive apnea-hypopnea index (11.1 [4.3-58.4] vs. 14.4 [10.3-23.3] events/h, respectively; p = .78). However, children with ROHHAD showed a significantly higher desaturation index compared to the control group (37.9 [13.7-59.8] vs. 14.7 [4.3-27.6] events/h; p = .05). While awake at rest, some children with ROHHAD experienced significant desaturations associated with central pauses. During the 6MWT, no significant desaturations were observed, but two children showed moderate functional limitation. CONCLUSIONS: Among children with ROHHAD, respiratory instability may be demonstrated by a significant number and severity of oxygen desaturations during sleep in the presence of OSA, with or without NH, and oxygen desaturations with central pauses at rest during wakefulness. Interestingly, during daily activities that require submaximal effort, children may not experience oxygen desaturations. Early recognition of respiratory abnormalities and targeted therapeutic interventions are important to limit associated morbidity and mortality in ROHHAD.

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.
