    Role of pediatricians, pediatric associations, and academic departments in ensuring optimal early childhood development globally: Position paper of the international pediatric association

    Early childhood (birth-8 years), particularly the first 3 years, is the most critical time in development because of the highly sensitive developing brain. Providing appropriate developmental care (i.e., nurturing care, as defined by the World Health Organization [WHO]) during early childhood is key to ensuring a child\u27s holistic development. Pediatricians are expected to play a critical role in supporting early childhood development (ECD) through providing developmental services such as developmental monitoring, anticipatory guidance, screening, and referral to medical and/or community-based services when delay is identified. Pediatricians are also expected to serve as advocates within their clinics and communities for improved delivery of ECD services, such as advocating for increasing funding for ECD initiatives, increasing insurance coverage of ECD services, and working to increase other pediatricians\u27 awareness of the principles of ECD and how to deliver developmental services. However, this does not always occur. Typically, pediatricians\u27 training and practice emphasizes treating disease rather than enhancing ECD. Pediatricians are further hindered by a lack of uniformity across nations in guidelines for developmental monitoring and screening. In this article, we present the vision of the International Pediatric Association (IPA) of the roles that pediatricians, academic departments, medical training programs, and pediatric associations should fulfill to help support ECD, including raising ECD to higher levels of priority in routine pediatric care. First, we present the challenges that face these goals in supporting ECD. We then propose, with supportive literature, strategies and resources to overcome these challenges in collaboration with local and international stakeholders, including the IPA, the WHO, UNICEF, and the World Bank

    Alternating hemiplegia of childhood: evolution over time and mouse model corroboration

    Alternating hemiplegia of childhood is a rare neurodevelopmental disorder caused by ATP1A3 mutations. Some evidence for disease progression exists, but there are few systematic analyses. Here, we evaluate alternating hemiplegia of childhood progression in humans and in the D801N knock-in alternating hemiplegia of childhood mouse, Mashlool, model. This study performed an ambidirectional (prospective and retrospective data) analysis of an alternating hemiplegia of childhood patient cohort (n = 42, age 10.24 +/- 1.48 years) seen at one US centre. To investigate potential disease progression, we used linear mixed effects models incorporating early and subsequent visits, and Wilcoxon Signed Rank test comparing first and last visits. Potential early-life clinical predictors were determined via multivariable regression. We also compared EEG background at first encounter and at last follow-up. We then performed a retrospective confirmation study on a multicentre cohort of alternating hemiplegia of childhood patients from France (n = 52). To investigate disease progression in the Mashlool mouse, we performed behavioural testing on a cohort of Mashlool' mice at prepubescent and adult ages (n =11). Results: US patients, over time, demonstrated mild worsening of non-paroxysmal disability index scores, but not of paroxysmal disability index scores. Increasing age was a predictor of worse scores: P< 0.0001 for the non-paroxysmal disability index, intellectual disability scale and gross motor scores. Earliest non-paroxysmal disability index score was a predictor of last visit non-paroxysmal disability index score (P= 0.022), and earliest intellectual disability score was a predictor of last intellectual disability score (P= 0.035). More patients with EEG background slowing were noted at last follow-up as compared to initial (P=0.015). Similar worsening of disease with age was also noted in the French cohort: age was a significant predictor of non-paroxysmal disability index score (P= 0.001) and first and last non-paroxysmal disability index score scores significantly differed (P=0.002). In animal studies, adult Mashlool mice had, as compared to younger Mashlool mice, (i) worse balance beam performance; (ii) wider base of support; (iii) higher severity of seizures and resultant mortality; and (iv) no increased predisposition to hemiplegic or dystonic spells. In conclusion, (i) non-paroxysmal alternating hemiplegia of childhood manifestations show, on average over time, progression associated with severity of early-life non-paroxysmal disability and age. (ii) Progression also occurs in Mashlool mice, confirming that ATP1A3 disease can lead to age-related worsening. (iii) Clinical findings provide a basis for counselling patients and for designing therapeutic trials. Animal findings confirm a mouse model for investigation of underlying mechanisms of disease progression, and are also consistent with known mechanisms of ATP1A3-related neurodegeneration
