Asthma and other allergic disorders, such as atopic dermatitis and food allergies, are common chronic health problems in childhood. The rapid rise in the prevalence of these conditions registered over the last few decades has stressed the need to identify the modifiable risk factors associated with the development of these diseases. Breast milk, recognized as the gold standard for healthy growth and development of the newborn, is one of the major factors associated with a lower incidence of allergic and infectious diseases in childhood and young adulthood. Although the underlying mechanisms for these effects are not well understood, breastfeeding leads to immune system maturation. In this narrative review, we summarize existing evidence on breastfeeding and human milk composition in relation to allergic disease prevention or development.

Nutraceuticals, including vitamin D, vitamin A, zinc, lactoferrin, polyphenols coenzyme Q, magnesium, and selenium, are implicated in the modulation of the complex molecular pathways involved in the immune response against viral pathogens. A common element of the activity of nutraceuticals is their ability to enhance the innate immune response against pathogens by acting on the major cellular subsets and inducing the release of pro-inflammatory cytokines and antimicrobial peptides. In some cases, this action is accompanied by a direct antimicrobial effect, as evidenced in the specific case of lactoferrin. Furthermore, nutraceuticals act through complex molecular mechanisms to minimize the damage caused by the activation of the immune system against pathogens, reducing the oxidative damage, influencing the antigen presentation, enhancing the differentiation and proliferation of regulatory T cells, driving the differentiation of lymphocyte subsets, and modulating the production of pro-inflammatory cytokines. In this paper, we review the main molecular mechanisms responsible for the immunomodulatory function of nutraceuticals, focusing on the most relevant aspects for the prevention and treatment of viral infections.

Introduction of complementary feeding, or weaning, is the period where infants are gradually introduced to solid foods, with a progressive reduction of breastfeeding or bottle‐feeding. Weaning represents a crucial nutritional moment in the growth and development of infants, and it can also affect future health. Throughout the years, various weaning strategies have been proposed, ranging from classic to baby‐led weaning. Recently, vegetarian‐/vegan‐based approaches are also being increasingly adopted by young parents. This rostrum aims to critically address the safety profiles of current weaning practices for infants and to highlight the important role of pediatricians in choosing the most advisable weaning approach for their patients.

Asthma is the most common chronic non-communicable disease in children, the pathogenesis of which involves several factors. The increasing burden of asthma worldwide has emphasized the need to identify the modifiable factors associated with the development of the disease. Recent research has focused on the relationship between dietary factors during the first 1000 days of life (including pregnancy)—when the immune system is particularly vulnerable to exogenous interferences—and allergic outcomes in children. Specific nutrients have been analyzed as potential targets for the prevention of childhood wheeze and asthma. Recent randomized controlled trials show that vitamin D supplementation during pregnancy, using higher doses than currently recommended, may be protective against early childhood wheezing but not school-age asthma. Omega-3 fatty acid supplementation during pregnancy and infancy may be associated with a reduced risk of childhood wheeze, although the evidence is conflicting. Data from observational studies suggest that some dietary patterns during pregnancy and infancy might also influence the risk of childhood asthma. However, the quality of the available evidence is insufficient to allow recommendations regarding dietary changes for the prevention of pediatric asthma. This review outlines the available high-quality evidence on the role of prenatal and perinatal nutritional interventions for the primary prevention of asthma in children and attempts to address unmet areas for future research in pediatric asthma prevention.

Carbon monoxide (CO) poisoning during pregnancy is a rare occurrence, associated with high maternal and fetal mortality rates. As CO can cross the placenta, leading to intrauterine hypoxia, CO intoxication can result in neurological sequelae and neurologic complications in fetuses who survive. We report a case of a preterm newborn acutely exposed to CO in-utero and delivered by emergent cesarean section at the 31st week of gestation due to the severe burns suffered by the mother following an indoor boiler explosion. As CO has serious adverse effects both on the mother and fetus, it is important to recognize and treat poisoning in a timely manner. Despite maternal blood CO levels, CO intoxication at critical stage of central nervous system development can lead to hypoxic-ischemic lesions, thus interdisciplinary care and follow up for these patients are mandatory.

Introduction: A recent retrospective study conducted in Tanzania reported that 87.5% of neonatal deaths occur within the first week of life, highlighting a critical opportunity to reduce mortality through improvements in the quality of care. The aim of this study is to describe a distance learning program supported by a newly developed device specifically designed for telesimulation-based training. This program was created to facilitate continuous professional development for healthcare personnel involved in neonatal care. Methods: After identifying sustainable objectives for improving the quality of neonatal care, a cooperative program was established. This initiative involved medical instrumentation providers and neonatologists to support on-site care and clinical coaching. A telesimulation tool, capable of being managed both locally and remotely, was developed and implemented to enhance accessibility and training sustainability. Results: The analysis conducted using an operational checklist applied to neonatal resuscitation simulations revealed a statistically significant improvement in performance, with an average percentage improvement of 38.78% for technical skills and 71.42% for nontechnical skills. Conclusions: This telesimulation tool demonstrated promising outcomes in reinforcing essential neonatal resuscitation knowledge. The innovative advantage of our simulation system lies in its dual-mode operation, functioning both autonomously on-site and under remote supervision. This capability establishes the foundation for a sustainable and continuous training model.
