Purpose:Assess whether ChatGPT 4.0 is accurate enough to perform research evaluations on journal articles to automate this time-consuming ***/methodology/approach:Test the extent to which ChatGPT-4 can assess the quality of journal articles using a case study of the published scoring guidelines of the UK Research Excellence Framework(REF)2021 to create a research evaluation *** was applied to 51 of my own articles and compared against my own quality ***:ChatGPT-4 can produce plausible document summaries and quality evaluation rationales that match the REF *** overall scores have weak correlations with my self-evaluation scores of the same documents(averaging r=0.281 over 15 iterations,with 8 being statistically significantly different from 0).In contrast,the average scores from the 15 iterations produced a statistically significant positive correlation of ***,averaging scores from multiple ChatGPT-4 rounds seems more effective than individual *** positive correlation may be due to ChatGPT being able to extract the author’s significance,rigour,and originality claims from inside each *** my weakest articles are removed,then the correlation with average scores(r=0.200)falls below statistical significance,suggesting that ChatGPT struggles to make fine-grained *** limitations:The data is self-evaluations of a convenience sample of articles from one academic in one *** implications:Overall,ChatGPT does not yet seem to be accurate enough to be trusted for any formal or informal research quality evaluation *** evaluators,including journal editors,should therefore take steps to control its ***/value:This is the first published attempt at post-publication expert review accuracy testing for ChatGPT.

Item-Level Analysis of the Revised Occupational Therapy Fieldwork Performance Evaluation Applied in Practice

引用

Open Journal of Therapy and Rehabilitation 2024年第2期12卷 145-159页

作者： Cynthia L. Sears Brad E. Egan Patricia F. tomsic Craig A. Velozo Graduate College of Health Professions Occupational Therapy Program Hawai&#8217i Pacific University Honolulu HI USA College of Science and Health Occupational Therapy Program DePaul University Chicago IL USA Department of Occupational Therapy Wingate University Wingate NC USA College of Health Professions Department of Rehabilitation Sciences Division of Occupational Therapy Medical University of South Carolina Charleston SC USA

Competency-based assessments for healthcare professionals are critical for safe and effective client outcomes. Rehabilitation clinical skill competency assessments must be validated and revised to produce safe and skilled practitioners. The revised American Occupational Therapy Association (AOTA) Fieldwork Performance Evaluation (FWPE) instrument measures occupational therapy student performance to determine readiness for practice. The assessment includes thirty-seven competencies that address both profession specific clinical skills and general professional behavior skills. The objective of this study was to use Rasch methods to explore the use of the revised FWPE in actual fieldwork practice and to determine the instrument’s psychometric properties when separating the item components into two distinct subdomains: General Health Professions Competences and Occupational Therapy-Specific Competencies. Internal construct validity and test reliability were analyzed using data from 149 occupational therapy students after completing their initial Level II A fieldwork clinical internship. This study examined the item difficulty hierarchy, item fit, person-fit to model, person separation index, person separation reliability coefficient, strata, ceiling and floor effect, and unidimensionality of the FWPE instrument as a whole and as two separate domains. With the exception of not meeting the criteria for unidimensionality, the full FWPE instrument and the Occupational Therapy-Specific Competencies subdomain showed acceptable item-level psychometrics for reliability and precision. While the General Health Professions Competencies subdomain showed good item-level psychometrics, it was below the criterion for reliability and only separated the sample into two strata. Results support the validity, reliability, and clinical use of the revised FWPE full instrument and the Occupational Therapy-Specific Competencies subdomain to measure entry-level clinical skill competencies in pr

Endoscopic ultrasound(EUS)with fine needle aspiration or fine needle biopsy is the gold standard for sampling tissue to diagnose pancreatic cancer and auto-immune pancreatitis or to analyze cyst *** most common reported adverse event of fine needle aspiration and/or fine needle biopsy is acute pancreatitis,which is likely induced by the same pathophysiological mechanisms as after en-doscopic retrograde cholangiopancreatography(ERCP).According to the current European Society of Gastrointestinal Endoscopy guideline,nonsteroidal anti-inflammatory drugs are administered prior to ERCP as a scientifically proven treatment to reduce post-ERCP pancreatitis incidence rate.A single suppository of diclofenac or indomethacin prior to EUS guided tissue acquisition(TA)is harm-less in healthy *** it is associated with low costs and,most important,may prevent a dreadsome complication,we strongly recommend the adminis-tration of 100 mg diclofenac rectally prior to *** will explain this recom-mendation in more detail in this review as well as the risk and pathophysiology of post-EUS TA pancreatitis.

A Rare Etiology of a Life-Threatening Subdural Hematoma: Case Report and Literature Review

引用

Open Journal of Modern Neurosurgery 2024年第2期14卷 108-113页

作者： Ibrahim Dao Hassan Baallal Narcisse mike Wendpuiré Ouédraogo Ousmane Ouattara Department of Neurosurgery University Hospital Souro Sanou Nazi Boni University Bobo Dioulasso Burkina Faso Higher Institute of Health Sciences Nazi Boni University Bobo Dioulasso Burkina Faso Department of Neurosurgery Avicenne Military Teaching Hospital University Caddi Ayyad Marrakech Morocco

Background: Life-threatening subdural hematoma is commonly related to trauma and rarely revealed by neoplasm. Observation: We report a case of a 53-year-old suffering from mild headache and without a history of trauma, was admitted unconscious due to a subdural hematoma on radiological investigations. Beside the left subdural hematoma, there was also alytic lesion of the sphenoid wing and the temporal bone on the same side. An emergent removal of the subdural hematoma and an excision of the bone lesion were performed. Pathological examination diagnosed a cavernous hemangioma of the skull. The postoperative period was uneventful with a dramatic recovery of the patient. Conclusion: A quick worsening of a chronic headache, acute impairment of an uncommon headache deserve prompt investigation and emergent surgical management in case of intracranial hematoma. Any bone and dural abnormalities at the vicinity of a subdural hematoma require total excision with clean border and pathological examination.
