161 Airway colonization in the first year of life of children with CF diagnosed by newborn screening: the experience of a Portuguese centre

Objetivo: A fenilcetonúria é uma das principais causas de deficiência intelectual, e possui tratamento eficaz, se realizado o diagnóstico e tratamento de forma precoce e um acompanhamento por toda vida. O objetivo deste trabalho é levantar a prevalência de recém-nascidos portadores de fenilcetonúria identificados pela triagem neonatal. Métodos: Estudo transversal no qual foi feito um levantamento de dados sobre triagem neonatal para doença fenilcetonúria realizada num Serviço de Referência de Triagem Neonatal, no período de 1 de janeiro de 2010 a 31 de dezembro de 2015. Resultados: Foi encontrado no período de 5 anos, uma prevalência aproximada de fenilcetonúria de 1: 14.700 e de hiperfenilalaninemia permanente é de 1: 54.500 nascidos vivos. Por meio dos resultados obtidos é possível demonstrar a relevância das recoletas e do seguimento no primeiro ano de vida e de amostras alteradas, assim como a gravidade da população feminina portadora de fenilcetonúria e hiperfenilalaninemia benigna, enfatizando o aumento de possíveis danos cerebrais na fase gestacional. Conclusão: A prevalência de fenilcetonúria e hiperfenilalaninemia permanente é alta. As recoletas e o seguimento no primeiro ano de vida das amostras alteradas é de extrema importância, principalmente para a população feminina portadora de fenilcetonúria e hiperfenilalaninemia permanente, enfatizando o aumento de possíveis danos cerebrais na fase gestacional. Palavras chave: Fenilcetonúrias, Fenilalanina, Triagem neonatal ABSTRACT: Abstract Phenylketonuria is one of the main causes of intellectual disability, and it has effective treatment, if the diagnosis and treatment is performed early and a lifelong follow-up. The objective of this study is to determine the prevalence of newborns with phenylketonuria identified by newborn screening. Methods: A cross-sectional study was carried out in which a data collection on newborn screening for phenylketonuria disease was carried out at the Newborn Screening Reference Service from January 1, 2010 to December 31, 2015. Results: It was found in a 5-year period, an approximate prevalence of phenylketonuria of 1: 14,700 and permanent hyperphenylalaninemia is 1: 54,500 newborns. By means of the obtained results, it is possible to demonstrate the relevance of the recollects and the follow-up in the first year of life and of altered samples, as well as the severity of the female population with phenylketonuria and permanent hyperphenylalaninemia, emphasizing the increase of possible brain damages in the gestational phase. Conclusion: The prevalence of phenylketonuria and permanent hyperphenylalaninemia is high. Recollect and follow-up in the first year of life of the altered samples is extremely important, especially for the female population with phenylketonuria and permanent hyperphenylalaninemia, emphasizing the increase of possible brain damage in the gestational phase.

Introduction: Newborn screening (NBS) for cystic fibrosis (CF) was implemented in all US states and DC by 2010. This hypothesis generating study was designed to form the basis of additional research and to plan quality improvement initiatives. The aims were to describe the outcomes of infants with CF born during the first 9 years of universal NBS. Methods: We included participants in the CF Foundation Patient Registry born 2010-2018 with age at first CF event (first sweat test, clinic visit or hospitalization) by age 365 days. We assessed age of center-reported diagnosis, age at first CF event, demographics and outcomes for three consecutive 3-year cohorts born in 2010-2012, 2013-2015, and 2016-2018. Results: In 6354 infants, median age at diagnosis was earlier than median age at first CF event, which decreased from 1st cohort to 3rd cohort. Weight-for-age (WFA) was < 10th percentile in about 40% of infants at the first CF Center visit. Median WFA z-score at 1-2 years was > 0 but height-for-age (HFA) z-score was < 0 through age 5-6 years. The second cohort had a higher HFA z-score than the first cohort at age 5-6 years. Pseudomonas aeruginosa infection rates decreased over time. About 1/3 of infants were hospitalized in the first year of life across cohorts. Conclusion: Over 9 years of CF NBS, median age at first CF event decreased. CF NBS had positive health impacts but improving nutritional deficits and reducing infant hospitalizations remain targets for improvement.

Diagnostic Delays

Pompe disease (PD) is a rare, autosomal-recessively inherited deficiency in the enzyme acid α-glucosidase. It is a spectrum disorder; age at symptom onset and rate of deterioration can vary considerably. In affected infants prognosis is poor, such that without treatment most infants die within the first year of life. To lose a baby in their first year of life to a rare disease causes much regret, guilt, and loneliness to parents, family, and friends. To lose a baby needlessly when there is an effective treatment amplifies this sadness. With so little experience of rare disease in the community, once a baby transfers to their home they are subject to a very uncertain and unyielding diagnostic journey while their symptomology progresses and their health deteriorates. With a rare disease like PD, the best opportunity to diagnose a baby is at birth. PD is not yet included in the current newborn screening (NBS) panel in Australia. Should it be? In late 2018 the Australian Pompe Association applied to the Australian Standing committee on Newborn Screening to have PD included. The application was not upheld. Here we provide an overview of the rationale for NBS, drawing on the scientific literature and perspectives from The Australian Pompe Association, its patients and their families. In doing so, we hope to bring a new voice to this very important debate.

Swallowing Apnea

Abstract Research exists that evaluates the mechanics of swallowing respiratory coordination in healthy children and adults as well and individuals with swallowing impairment. The research program summarized in this article represents a systematic examination of swallowing respiratory coordination across the lifespan as a means of behaviorally investigating mechanisms of cortical modulation. Using time-locked recordings of submental surface electromyography, nasal airflow, and thyroid acoustics, three conditions of swallowing were evaluated in 20 adults in a single session and 10 infants in 10 sessions across the first year of life. The three swallowing conditions were selected to represent a continuum of volitional through nonvolitional swallowing control on the basis of a decreasing level of cortical activation. Our primary finding is that, across the lifespan, brainstem control strongly dictates the duration of swallowing apnea and is heavily involved in organizing the integration of swallowing and respiration, even in very early infancy. However, there is evidence that cortical modulation increases across the first 12 months of life to approximate more adult-like patterns of behavior. This modulation influences primarily conditions of volitional swallowing; sleep and naïve swallows appear to not be easily adapted by cortical regulation. Thus, it is attention, not arousal that engages cortical mechanisms.
