The rising rates of food allergies in Australia and other countries prompted a review of infant feeding guidelines, to review the evidence behind the increasing rates of allergies and anaphylaxis. Australia saw a five fold increase in hospitalisation with anaphylaxis between 1995 and 2005, which sadly also saw an increase in the number of fatalities from anaphylaxis. The Australasian Society for Clinical Immunology and Allergy (ASCIA) released new guidelines for the introduction of allergenic foods to infants in 2016, focusing on introducing potentially allergenic foods before the age of 12 months. This is in contrast to the previous recommendations of avoiding these types of foods until the age of 1-3 years.
The new infant feeding guidelines have had very positive results, with many parents and healthcare professionals embracing the change. Recent studies into the prevalence of allergies in infants has explored the rates of peanut allergies in Victorian infants, called the ‘The EarlyNuts Study’. Researchers found that despite concerns parents would not introduce potentially allergenic foods to infants, 89% of infants had consumed peanuts before reaching 12 months. This has seen a 16% decrease in the rates of peanut allergies, which supports the latest guideline updates. Further research in the ongoing ‘Vitality Trial’ is exploring if the use of vitamin D supplements can further reduce the risk of peanut allergies, as infants with peanut allergies have been found to be vitamin D deficient in a number of studies.

Antiseptic Non-Touch Technique (ANTT®) plays a critical role in managing Central Venous Access Devices (CVADs) to prevent infections. While both standard and surgical ANTT approaches aim to maintain asepsis during procedures, they differ significantly in their application and outcomes. Understanding these distinctions ensures healthcare providers optimise infection control and patient safety in wound care and CVAD management.
