: Narration is a sensitive tool for the assessment of language in children with high-functioning autism spectrum disorder (HF-ASD) since mild language deficits beyond the sentential level are not always noticeable through the administration of standardized language tests targeting the lexical or sentential level. This study investigated the narrative ability of monolingual Greek-speaking HF-ASD children in comparison to that of their typically developing (TD) peers and explored the associations between narrative variables, ADHD symptomatology, and memory skills in the participants on the autistic spectrum. : The participants were 39 children aged 7 to 12 years, 19 with HF-ASD and 20 age-matched, vocabulary-matched, and cognitively matched TD peers.

Introduction: Maternal infections such as chorioamnionitis could impact fetal lung development by altering cell proliferation and apoptosis. Chorioamnionitis favors the multiple pleiotropic cytokines production such as LIF (leukemia inhibitory factor) and an inflammation-related protein p53. The cytokine production can lead to lung tissue damage and lung disease development.

Aim: Irisin, a newly discovered adipomyokine, has pleiotropic effects in metabolic and energy homeostasis, insulin resistance (IR), and browning of white adipose tissue. The aim of this study was to evaluate irisin levels in children with obesity and also to elucidate possible relationships between irisin with anthropometric obesity indices, parameters of metabolic syndrome (MetS), and intima media thickness (IMT).

Methods: A total of 77 prepubertal children, 4-12 years old, were enrolled in this study, including 44 children with obesity (BMI ≥ 95th percentile) and 33 normal weight controls of matched age and gender.

Kyriakou" Children's Hospital, Athens, Greece. Electronic address:

The orchestration of dynamic epigenetic and epitranscriptomic modifications is pivotal for the fine-tuning of gene expression. However, these modifications are traditionally examined independently. Recent compelling studies have disclosed an interesting communication and interplay between m6A RNA methylation (m6A epitranscriptome) and epigenetic modifications, enabling the formation of feedback circuits and cooperative networks.

Article Synopsis
  • The study investigates the immune response in children with Multisystem Inflammatory Syndrome (MIS-C) following COVID-19, focusing on T-cell cytokine profiles before and after treatment.
  • Researchers compared T-cell markers in four groups of children: those with acute MIS-C, those recovering from MIS-C, post-COVID-19 patients, and healthy controls, using advanced flow cytometry.
  • Results showed significant differences in T-cell expression of IL-17 and IFNγ in children with acute MIS-C, suggesting these markers could serve as biomarkers for identifying the condition.

Article Synopsis
  • Variants in the GNB1 gene are linked to intellectual development disorders and can lead to a range of symptoms including developmental delays, hypotonia, seizures, and psychiatric issues, as well as multisystem disorders affecting hearing, vision, and growth.
  • The study presents two pediatric cases with novel GNB1 gene variants: one 12-year-old girl with a history of hypotonia and obesity, and one 2-year-old girl with severe failure to thrive and congenital hypothyroidism, both showing significant health challenges.
  • The findings suggest that GNB1 gene variations can result in diverse symptoms and may be important in understanding severe early onset obesity and other related metabolic and endocrine disorders.
