Efficacy and Safety of Subcutaneous Efgartigimod PH20 in Adults With Primary Immune Thrombocytopenia (ADVANCE SC): A Multicenter, Randomized, Double‐Blinded, Placebo‐Controlled, Phase 3 Trial

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Primary autoimmune thrombocytopenia (ITP) is characterized by thrombocytopenia, bleeding, and reduced health‐related quality of life. In the Phase 3 ADVANCE IV study, intravenous efgartigimod induced significant platelet count responses versus placebo in patients with chronic ITP. ADVANCE SC, a Phase 3, multicenter, randomized, double‐blinded,

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...
