RESUMO
Background: The manifestation of bulbar symptoms, especially swallowing, is important for evaluating disease-modifying therapies for spinal muscular atrophy (SMA). Due to the lack of instruments, the topic is still underrepresented in research. Objective: This study aimed to develop a tool to monitor swallowing development in children aged 0 to 24 months with SMA. Methods: The method was guided by the COSMIN guidelines and followed a multi-stage Delphi process. The first step was a rapid review of swallowing outcomes in children with SMA younger than 24 months. In the second step, online group interviews with experts (nâ=â7) on dysphagia in infants were conducted, followed by an anonymous online survey among experts in infants with SMA (nâ=â19). A predefined consensus threshold for nominal scaled voting was set at≥75 % and for 5-point Likert scale voting at 1.25 of the interquartile range. The third step was the pilot test of the instrument, performed with three groups (healthy controls nâ=â8; pre-symptomatic nâ=â6, symptomatic nâ=â6). Results: Based on the multi-level interprofessional consensus, the DySMA comprises two parts (history and examination), ten categories, with 36 items. Implementation and scoring are clearly articulated and easy to implement. The pilot test showed that swallowing development could be recorded in all groups. Conclusion: The DySMA is well suited for monitoring swallowing development in pre-symptomatic and symptomatic treated infants with SMA. It can be performed in a time-efficient and interprofessional manner. The resulting score is comparable to results from other instruments measuring other domains, e.g., motor function.

OBJECTIVES: This prospective multicenter study aimed (1) to examine changes in parent-reported health-related quality of life (HRQOL) of children with short stature and the effects of the children's condition on parents themselves within the first year of human growth hormone (hGH) treatment and (2) to predict effects on parents based on main and interaction effects of children's HRQOL and increase in height. METHODS: A total of 110 parents of children aged 4-18 years, diagnosed with idiopathic growth hormone deficiency, small for gestational age, or idiopathic short stature, were recruited from 11 participating German pediatric endocrinologists and asked to fill out the short stature-specific Quality of Life in Short Stature Youth (QoLISSY) Questionnaire before hGH treatment was initiated and one year later. RESULTS: Negative effects of the children's short stature on the parents decrease over time, independent of diagnosis and treatment status. Furthermore, treatment status and height increase moderated the links between children's improved HRQOL as perceived by their parents and decreased caregiving burden. CONCLUSIONS: Based on the children's improved HRQOL and the parent's decrease in caregiving burden, patient-reported outcomes that consider parental and child's perspectives should be considered when deciding on hGH treatment for children.
