Situational factors can influence cognitive performance and should be considered for conducting cognitive assessments. The objective of this project was to develop a checklist for Cognitive Assessment Requirements (CARE) to identify these situational factors before conducting cognitive assessments and account for them. This study employed a four-round Delphi approach involving 22 experts to identify situational factors that can impact cognitive assessment results.

Introduction: The optimal treatment of estrogen receptor-positive (ER +) metastatic breast cancer (MBC) after progression on cyclin-dependent 4/6 kinase inhibitors (CDK4/6i) is unknown.

Methods: We conducted a systematic review and network meta-analysis (NMA) of phase-II/-III randomized trials of ER + MBC post CDK4/6i + ET progression. We calculated the hazard ratio (HR) for progression-free survival (PFS) and overall survival (OS) using generic inverse variance and odds ratios (ORs) using the Mantel-Haenszel method for adverse events (AEs) with Review-Manager version-5.

This column is intended to address the kinds of knotty problems and dilemmas with which many scholars grapple in studying health professions education. In this article, we address the dilemma of engaging with foundational works versus depending on summary articles. We argue that an over-dependence on secondary sources can lead to prejudices and unquestioned assumptions, and limit the constructive development of our field.

Ann Thorac Surg

February 2025

Department of Surgery, University of Ottawa, Ottawa, Ontario, Canada; Division of Thoracic Surgery, The Ottawa Hospital, Ottawa, Ontario, Canada. Electronic address:

Background: In 2007, Cancer Care Ontario created Thoracic Surgical Oncology Standards for the delivery of surgery, including lobectomy, esophagectomy, and pneumonectomy. These standards regionalized thoracic surgery into designated centers and mandated physical and human resources. This analysis sought to identify the impact of these standards, hereafter referred to as "regionalization," on outcomes after thoracic oncology surgery in Ontario, Canada.

Adolescents and young adults (AYAs; ages 15-39 years) are a vulnerable population facing challenges in oncological care, including access to specialized care, transition of care, unique tumor biology, and poor representation in clinical trials. Brain tumors are the second most common tumor type in AYA, with malignant brain tumors being the most common cause of cancer-related death. The 2021 WHO Classification for central nervous system (CNS) Tumors highlights the importance of integrated molecular characterization with histologic diagnosis in several tumors relevant to the AYA population.

Article Synopsis
  • The study aimed to analyze the relationship between the sex of surgeons and the number of days patients spend alive and at home (DAH) after surgery.
  • It found that patients treated by female surgeons had significantly more DAH compared to those treated by male surgeons over all measured time frames (30, 90, and 365 days).
  • The findings suggest that higher DAH associated with female surgeons could lead to lower healthcare costs and better patient quality of life, indicating a need for further research in different healthcare settings.
