The neonatal skin undergoes significant development in its lipid barrier, which plays a crucial role in protecting the infant from environmental stressors and pathogens. At birth, the lipid barrier is immature, making the skin more vulnerable to irritants and dehydration. Over time, this barrier strengthens, helping to maintain hydration and prevent infections. Understanding this development is vital for providing proper skin care and preventing conditions like eczema and skin infections in newborns.
The first 1,000 days of life, from conception to age two, are critical for a child’s physical, cognitive, and emotional development. Recent advances in preventive paediatrics highlight this period as crucial for fostering lifelong resilience. Early nutrition, responsive caregiving, and safe environments profoundly influence brain development and long-term health outcomes. Interventions during this phase include maternal health optimisation, breastfeeding support, timely immunisations, developmental screenings, and caregiver education. Tackling social factors like poverty, parental mental health, and healthcare access is equally vital. By focusing on early prevention and holistic support, paediatric care is shifting from disease treatment to long-term health promotion. Strengthening resilience in the first 1,000 days lays the foundation for healthier, more adaptable individuals throughout life.
Early-life exposure to antibiotics has been increasingly associated with disruptions in gut microbiota, potentially influencing immune and metabolic development. Epidemiological and experimental studies suggest that antibiotic use in infancy may heighten the risk of atopic conditions such as asthma, eczema, and allergic rhinitis, as well as metabolic disorders including obesity and insulin resistance. The critical window of immune programming during infancy underscores the importance of judicious antibiotic prescribing. Understanding the underlying mechanisms, such as microbial dysbiosis, altered short-chain fatty acid production, and immune modulation, can help inform preventive strategies and promote long-term health outcomes in paediatric populations.
