Introduction: The aims of the study were to describe the neurodevelopmental outcome of extremely low birth weight (ELBW) infants with parenteral nutrition-associated cholestasis (PNAC) and to assess whether PNAC is associated with adverse neurodevelopmental outcome.

Methods: The study is a secondary analysis of controlled trial (June 2012-October 2017) on PNAC incidence in ELBW infants receiving two different parenteral lipid emulsions (mixed lipid emulsion containing fish oil vs. soybean oil-based). Neurodevelopmental follow-up at 12- and 24-month corrected age was compared in infants with and without PNAC. A machine learning-based regression analysis was used to assess whether PNAC was associated with adverse neurodevelopmental outcome.

Results: For assessment of neurodevelopmental outcome (Bayley-III), 174 infants were available at 12-month (PNAC: n = 21; no PNAC: n = 153) and 164 infants at 24-month (PNAC: n = 20; no PNAC: n = 144) corrected age. The neurodevelopment of ELBW infants with PNAC was globally delayed, with significantly lower cognitive, language, and motor scores at both 12- and 24-month corrected age. Regression analyses revealed that PNAC was associated with an adverse motor outcome.

Conclusion: ELBW infants with PNAC are at increased risk for adverse neurodevelopmental outcome.

Background: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition emerging in early childhood, characterized by core features such as sociocommunicative deficits and repetitive, rigid behaviors, interests, and activities. In addition to these, disruptive behaviors (DB), including aggression, self-injury, and severe tantrums, are frequently observed in pediatric patients with ASD. The atypical antipsychotics risperidone and aripiprazole, currently the only Food and Drug Administration-approved treatments for severe DB in patients with ASD, often encounter therapeutic failure or intolerance.

Developmental and epileptic encephalopathies constitute a group of severe epilepsies, with seizure onset typically occurring in infancy or childhood, and diverse clinical manifestations, including neurodevelopmental deficits and multimorbidities. Many have genetic aetiologies, identified in up to 50% of individuals. Whilst classically considered paediatric disorders, most are compatible with survival into adulthood, but their adult phenotypes remain inadequately understood.

Objective: To investigate the prognosis and co-occurring disorders, including functional neurological symptoms, in adolescents diagnosed with functional tic-like behaviour (FTLB).

Design: This was a single-centre tertiary study in the UK. A structured clinical interview was administered to 43 parents or carers of adolescents assessed with FTLB at their previous outpatient clinic appointment.
