まとめ
マルチモダルの大型言語モデル (LLM) は,緊急放射線写真からの骨折の検出において中等から良好な合意を示したが,非移転骨折では苦労した. 専門家のレビューは,整形外傷診断における患者の安全性にとって不可欠です.
科学分野:
- 医療における人工知能
- 放射線解釈技術について
- 整形外傷診断 整形外傷診断
背景:
- 緊急治療室 (ED) での骨折の正確な検出は,高い患者数と時間圧迫のため,診断エラーを増やすことが不可欠です.
- 画像認識を備えたマルチモダル大型言語モデル (LLM) は,臨床的意思決定支援の可能性を秘めているが,ED整形外科画像処理のワークフローにおけるその有用性は十分に定義されていない.
研究 の 目的:
- ED患者の骨折検出のための整形外科医の専門家と比較して,マルチモダルのLLMの診断の正確性と合意を評価する.
- 整形外科のトラウマに対する現実世界の臨床ワークフローにおけるLLMのパフォーマンスを評価する.
主な方法:
- 1136人の連続したED患者で,整形外科に紹介された後の研究.
- 非常用放射線写真と臨床データは,マルチモダルのLLM (2025版) によって処理されました.
- LLMのアウトプットは,コーエンのカッパ,感度,特異性,および精度を使用して,盲目の整形外科医による最終診断と比較されました.
主要な成果:
- LLMは,専門医との診断合意 (71.1%; κ = 0.634) を中等から良好に達成しました.
- 感度は76.9%で,特異性は66.8%で,膝のトラウマの合意が最も高かった.
- 偽陰性症例 (16.2%) は,特に足首と足の部位 (それぞれ30.4%と17.4%のFN率) で,非移転骨折で頻繁に発生しました.
結論:
- マルチモダルのLLMは,ED整形外科イメージングにおける意思決定支援ツールとして有望ですが,まだ信頼性の高いスタンドアロン診断システムではありません.
- LLMの微妙で移動していない骨折を検出する限界は,患者の安全にリスクをもたらし,専門家の通訳の継続的な必要性を強調しています.
- ルーチン的な臨床採用の前に,最適化されたアルゴリズムによるさらなる前向きな,マルチセンター研究が必要である.

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Language
921
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

Improving Translational Accuracy
15.0K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Emerging Adulthood
728
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Acute Pyelonephritis II: Diagnostic Studies and Management
456
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
