Outcomes of X-Linked Agammaglobulinaemia Patients.

Background: X-linked agammaglobulinaemia (XLA), caused by mutations in BTK, is characterised by low or absent peripheral CD19 + B lymphocytes and agammaglobulinaemia. The mainstay of treatment consists of immunoglobulin replacement therapy (IgRT). As this cannot fully compensate for the immune defects in XLA, patients may therefore continue to be at risk of complications.

Local adaptation to climate facilitates a global invasion.

Local adaptation may facilitate range expansion during invasions, but the mechanisms promoting destructive invasions remain unclear. Cheatgrass (), native to Eurasia and Africa, has invaded globally, with particularly severe impacts in western North America. We sequenced 307 genotypes and conducted controlled experiments.

Multisystem Inflammatory Syndrome in Children and Cardiac Involvement: A Quaternary Center Experience.

We prospectively analyzed clinical and laboratory characteristics associated with cardiac involvement and severe presentation in multisystem inflammatory syndrome in children. Of 146 patients, 66 (45.2%) had cardiac dysfunction and 26 (17.

Surgical outcomes of infective endocarditis in pediatrics: Moving the needle to a contemporary, multidisciplinary approach.

Background: Infective endocarditis (IE) is an uncommon disease in children that, when present, is accompanied by significant morbidity and mortality. The presence of congenital heart disease often complicates management. The aim of the present study is to describe the characteristics and outcomes of children undergoing surgery for IE.
