Biologics and small molecules: the re-evolution in the treatment of atopic dermatitis in children and adolescents. Current state of the art and future perspectives.

Introduction: In recent years, the understanding of atopic dermatitis (AD) pathogenetic mechanisms has expanded and now it is recognized that Th2 immune axis dysregulation is pivotal to AD pathogenesis. The advent of biological drugs and small molecules have marked a revolution in the treatment of AD. Dupilumab, targeting IL-4 and IL-13, has been the first to demonstrate efficacy in treating moderate to severe AD by modulating type-2 inflammation pathways.

Functional Gastrointestinal Disorders and Childhood Obesity: The Role of Diet and Its Impact on Microbiota.

Introduction Emerging evidence suggests an association between obesity and Functional Gastrointestinal Disorders (FGIDs). Childhood obesity and FGIDs share many common features, such as high prevalence in the pediatric population, risk factors related to diet and lifestyle, gut microbiota impairments, and psychological distress. This narrative review aims to summarize the main evidence regarding FGIDs in childhood obesity, with a specific focus on the role of diet and its impact on the microbiota.

Planetary Health Diet for Childhood Obesity Prevention: Integrating Nutritional Health with Environmental Stewardship.

Background: Childhood obesity is a critical public health challenge with a rising prevalence worldwide, contributing to numerous health risks and long-term societal burdens. Concurrently, climate change and environmental degradation demand sustainable approaches to dietary patterns. The Planetary Health Diet (PHD), initially designed for adults, emphasizes plant-based foods and sustainable practices.

Hypothalamic-pituitary-adrenal axis in anorexia nervosa; an underestimated endocrine dysfunction among adolescents.

In patients affected by anorexia nervosa (AN) different endocrine abnormalities have been described, but, among them, hypothalamic-pituitary-adrenal (HPA) dysfunction, although associated to important side effects, is underestimated and has no therapeutical options. We present a narrative literature review to investigate the HPA axis in patients with AN, in order to highlight HPA dysfunction and its effects. We also described the crucial role of HPA monitoring, and to consider eventual therapeutic and preventive strategies in AN patients.

Comparison of qPCR protocols for quantification of "Candidatus Saccharibacteria", belonging to the Candidate Phyla Radiation, suggests that 23S rRNA is a better target than 16S rRNA.

Background: Candidate Phyla Radiation (CPR) is a large monophyletic group encompassing about 25% of bacterial diversity. Among CPR, "Candidatus Saccharibacteria" is one of the most clinically relevant phyla. Indeed, it is enriched in the oral microbiota of subjects suffering from immune-mediated disorders and it has been found to have immunomodulatory activities.
