The Wisconsin Card Sorting Test (WCST) is a popular neuropsychological test that is complicated to score and interpret. In an attempt to make scoring of the WCST simpler, Berry (The Clinical Neuropsychologist 10, 117-121, 1996) developed a diagrammatic scoring procedure, particularly to aid scoring of perseverative responses. We identified key limitations of Berry's diagram, including its unnecessary ambiguity and complexity, use of terminology different from that used in the standardized WCST manual, and lack of distinction between perseverative errors and perseverative responses.

Article Synopsis
  • The study examines the expression of HER2, an important biomarker for identifying and treating several types of cancers, including breast and gastroesophageal cancers, and its emerging relevance in other cancer types.
  • Conducted at a Canadian academic cancer center, the research sampled 499 solid tumors from adult patients between July 2020 and November 2023, excluding standard HER2-targeted malignancies.
  • Results indicated that HER2 expression levels varied across 42 cancer types, with a median turnaround time for test results being 18 days, which aligns with the feasibility for clinical decision-making.

Background: Growing evidence suggests that it is possible to change the retail food environment to enable healthier choices via in-store interventions. It has been difficult to draw clear conclusions as to which interventions are most effective in positively influencing consumer purchasing behaviour given the significant heterogeneity within the food retail research literature. The aim of this study was to (1) summarise current high-quality systematic, scoping, and/or narrative reviews (Part I: overview of reviews); and (2) synthesise high-quality original research, to understand the range, types and effectiveness of strategies implemented in food retail settings (Part II: evaluation of primary studies).

Introduction: People with persistent pain experience problems modifying their cognition and behaviours when task or environmental demands change - abilities otherwise known as . However, limitations and inconsistent results of previous studies raise concerns over the quality of that evidence. We aimed to determine whether people with and without persistent pain differ on two assessments that are commonly used to assess cognitive flexibility.
