Factors Associated with Shock at Presentation in Kawasaki Disease Versus Multisystem Inflammatory Syndrome in Children Associated with COVID-19.

Background: While clinical overlap between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C) has been evident, information regarding those presenting with shock has been limited. We sought to determine associations with shock within and between diagnosis groups.

Methods: The International KD Registry enrolled contemporaneous patients with either KD or MIS-C from 39 sites in 7 countries from 01/2020 to 01/2023.

Coding-Sequence Evolution Does Not Explain Divergence in Petal Anthocyanin Pigmentation Between Mimulus luteus Var luteus and M. l. variegatus.

Biologists have long been interested in understanding genetic constraints on the evolution of development. For example, noncoding changes in a gene might be favored over coding changes if they are less constrained by pleiotropic effects. Here, we evaluate the importance of coding-sequence changes to the recent evolution of a novel anthocyanin pigmentation trait in the monkeyflower genus Mimulus.

Safety outcomes of suspected cardiac pathology assessed in an ambulatory rapid-access cardiology clinic.

Cardiac pathology contributes to a significant proportion of emergency department (ED) attendances. Many could be managed as urgent outpatients and avoid hospital admission. We evaluated a novel rapidaccess general cardiology clinic to achieve this, implemented during the COVID-19 pandemic.
