Atopic dermatitis (AD) is a significant health concern for infants across the globe. Consequently, experts are prioritizing atopic dermatitis prevention to reduce the long-term psychosocial and financial burden on families. Recent reviews of clinical trials published between 2020 and 2025 suggest that specific interventions during early infancy may offer protective benefits. Specifically, researchers are evaluating the efficacy of moisturizers and probiotics as primary tools for risk reduction.
Moisturizers have historically shown mixed results in preventing eczema. However, new evidence from the 2025 CASCADE trial indicates that daily emollient application from nine weeks of age can significantly reduce AD incidence by two years. Furthermore, this study suggests that even infants not selected for high genetic risk can benefit from regular barrier support. In contrast, earlier meta-analyses warned of potential increases in skin infections, highlighting the need for careful application techniques.
Additionally, probiotics represent a promising \"inside-out\" approach to prevention. Recent systematic reviews demonstrate that oral probiotic supplementation during pregnancy and early infancy may reduce AD risk by approximately 26%. This benefit likely stems from the modulation of the gut-skin axis, which helps regulate the developing immune system. Nevertheless, trial heterogeneity and varying probiotic strains make it difficult to establish a universal protocol for all patients.
While these interventions show potential, firm conclusions remain elusive. Doctors must consider the heterogeneity of trial designs and the varying definitions of AD used in research. Moreover, clinical effects are often relatively small or inconsistent across different populations. Therefore, healthcare providers should personalize prevention strategies based on individual risk factors and family history.
Recent evidence suggests that daily moisturizer use from early infancy may reduce the incidence of AD, particularly by supporting the skin barrier. However, results vary between high-risk and general populations.
Probiotic supplementation during pregnancy and infancy may reduce the risk of developing atopic dermatitis by influencing the gut-skin axis. Current research indicates a potential risk reduction of around 26%.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
