Background: An aging population in combination with more gentle and less stressful surgical procedures leads to an increased number of operations on older patients. This collectively raises novel challenges due to higher age heavily impacting treatment. A major problem, emerging in up to 50% of cases, is perioperative delirium.

Children with autism and their parents face daily challenges that may be stressful for both. However, little is known about biological stress (hair cortisol concentrations [HCC]) in these families and its connection to children's health outcomes. This study investigates biological stress in children with autism and their parents and its associations with child mental health, eating behavior and BMI.

Brain tumours are one of the most deadly and noticeable types of cancer, affecting both children and adults. One of the major drawbacks in brain tumour identification is the late diagnosis and high cost of brain tumour-detecting devices. Most existing approaches use ML algorithms to address problems, but they have drawbacks such as low accuracy, high loss, and high computing cost.

Nanosecond pulse power has many driving advantages in the dielectric barrier discharge (DBD) application field, including better discharge effect, higher discharge efficiency, and lower electrode temperature. A high-voltage pulse voltage power supply (HV-PVPS) with a multi-turn ratio linear pulse transformer (PT) based on Marx circuit and PT topologies are suitable for most DBD plasma applications with fewer expansion modules, lower cost, smaller volume, and higher reliability comparing with the all-solid-state Marx nanosecond pulse power supply. However, during the process of DBD driven by an HV-PVPS based on Marx and PT topologies, the PT is prone to magnetic core saturation, which limits the application for DBD.
