Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Sex‐specific differences in mortality and neurocardiac interactions in the Kv1.1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP)

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The Kcna1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP) exhibits sex‐specific differences in SUDEP risk. Female mice exhibit a lower SUDEP risk than males, despite similar seizure characteristics and interictal cardiac function across sexes.

Cytologic Findings in Esophageal Perforation: An Institutional Experience With Pleural Fluid Specimens

open access: yesDiagnostic Cytopathology, Volume 54, Issue 6, Page 429-435, June 2026.
ABSTRACT Introduction Esophageal perforation (EP) is a rare but life‐threatening condition, and most cases are due to iatrogenic causes. The rest occur spontaneously, due to malignancies, or trauma. The mortality rates can approach 50%, and delayed diagnosis of EP exacerbates patient outcomes.

Perioperative Piperacillin/Tazobactam Reduces Early Onset SSI in Preirradiated Patients Undergoing Microvascular Head and Neck Reconstruction

open access: yesHead &Neck, Volume 48, Issue 6, Page 1519-1528, June 2026.
ABSTRACT Background Preirradiated patients undergoing microvascular head and neck reconstruction for tumor recurrence or osteoradionecrosis (ORN) face surgical site infection (SSI) rates exceeding 30%. The impact of perioperative extended‐spectrum antibiotic coverage remains unclear. This study hypothesizes that calculated prophylaxis with piperacillin/
