Article Synopsis
  • - The study aimed to analyze the endodontic anatomy of the dog's maxillary fourth premolar tooth (MxPM4), explore variations in its structure, and discuss its significance for dental treatments.
  • - Using micro-computed tomography (micro-CT), researchers examined ten teeth and found that the shape of the pulp chamber generally reflected the crown's morphology, with distinct pulp horns related to specific tooth structures but with variations found between them.
  • - The findings suggest that the typical method for root canal treatment may be inadequate due to the angulated canals and varying canal orifice locations, highlighting previously undocumented anatomical features in canine teeth.

Orthopedic surgery and surgery for cancer are major risk factors for venous thromboembolism (VTE). Deep vein thrombosis (DVT) can occur in up to 50% of patients after major orthopedic surgery. The rate of VTE after cancer surgery varies according to the type of surgery, with rates as high as those after orthopedic surgery in certain settings.

 The Perioperative Anticoagulation Use for Surgery Evaluation (PAUSE) Study assessed a standardized perioperative management strategy in patients with atrial fibrillation who were taking a direct oral anticoagulant (DOAC) and required an elective surgery or procedure. The aim of this substudy is to analyze the safety of this management strategy across different patient subgroups, according to four presurgical variables: (1) DOAC type and dose, (2) surgery/procedure bleed risk, (3) patient renal function, and (4) age.  Clinical outcomes analyzed included major bleeding (MB), arterial thromboembolism, any bleeding, and any thromboembolism.
