AI Article Synopsis

  • Evidence-based practice (EBP) challenges traditional methods in speech-language pathology and audiology by promoting a more scientific approach to clinical decision-making.
  • The paper discusses how EBP provides specific criteria for evaluating diagnostic procedures and encourages higher quality research in the field.
  • Learning outcomes include understanding the importance of rigorous studies, identifying EBP evaluation criteria, interpreting diagnostic accuracy measures, and recognizing the limitations of small sample studies.

Article Abstract

Unlabelled: Evidence-based practice (EBP), a framework that originated in clinical medicine, offers a principled means of addressing longstanding questions about clinical practice in communication disorders. However, in several respects EBP represents a radical departure from traditional thinking in speech-language pathology and audiology. In this paper, I first describe some of the ways in which the EBP orientation challenges conventional wisdom. I then describe criteria from the EBP literature to be used in evaluating evidence on diagnostic procedures. Using EBP criteria to design, conduct, and interpret studies will increase the quality of evidence available to support clinical decision-making in communication disorders, and to the credibility of the field as a whole.

Learning Outcomes: (1) Readers will be able to explain why rigorous scientific studies provide a stronger basis for clinical decision-making than do the opinions of authorities. (2) Readers will be able to list five EBP criteria for evaluating a study of diagnosis. (3) Readers will be able to describe and interpret two measures of diagnostic accuracy. (4) Readers will be able to explain the limitations of small-sample studies of diagnostic procedures.

"The Brain is…": A Survey of the Brain's Many Definitions.

Neuroinformatics

January 2025

Department of Psychiatry and Biobehavioral Sciences, University of California, Los Angeles, 760 Westwood Plaza, Los Angeles, CA, 90024, USA.

A reader of the peer-reviewed neuroscience literature will often encounter expressions like the following: 'the brain is a dynamic system', 'the brain is a complex network', or 'the brain is a highly metabolic organ'. These expressions attempt to define the essential functions and properties of the mammalian or human brain in a simple phrase or sentence, sometimes using metaphors or analogies. We sought to survey the most common phrases of the form 'the brain is…' in the biomedical literature to provide insights into current conceptualizations of the brain.

Objectives: It is uncertain what the effects of introducing digital breast tomosynthesis (DBT) in the Dutch breast cancer screening programme would be on detection, recall, and interval cancers (ICs), while reading times are expected to increase. Therefore, an investigation into the efficiency and cost-effectiveness of DBT screening while optimising reading is required.

Materials And Methods: The Screening Tomosynthesis trial with advanced REAding Methods (STREAM) aims to include 17,275 women (age 50-72 years) eligible for breast cancer screening in the Netherlands for two biennial DBT screening rounds to determine the short-, medium-, and long-term effects and acceptability of DBT screening and identify an optimised strategy for reading DBT.

Benign disorders of the mediastinum: a narrative review.

Mediastinum

September 2024

Divisions of Critical Care, Pulmonary and Sleep Medicine, Department of Internal Medicine, McGovern Medical School, The University of Texas Health Science Center (UTHealth), Houston, TX, USA.

Background And Objective: There are several benign processes that affect the mediastinum with considerable morbidity that may range from reactive entities to neoplastic disorders. This review article will focus on non-neoplastic benign mediastinal diseases which include large vessel vasculitis such as Takayasu and giant cell arteritis, mediastinal granulomas, fibrosing mediastinitis and mediastinal infections. These diseases can cause significant morbidity and mortality; therefore, we aim to familiarize readers with the pathophysiology, epidemiology and diagnosis of these mediastinal diseases and provide an update on the treatment options available.

The article focuses on a careful description of literature on stylometry and on its potential use in forensic science. The state of the art of stylometry is summarized to illustrate the history and the scientific foundation of this discipline. However, the study conducted reveals that there are still some key unresolved aspects that require a response from the academic world.
