Chronic Kidney Disease II: Clinical Manifestations01:24

Chronic Kidney Disease II: Clinical Manifestations

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease III: Clinical Manifestations

299
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis II: Clinical Features of Infective Endocarditis

364
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart Failure III: Clinical Manifestations

436
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Gastroesophageal Reflux Disease II: Clinical Features and Management

652
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

Hypertension III: Clinical Manifestations and Diagnostic Studies

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

科学分野:

  • 人工知能;自然言語処理;医療情報学

背景:

  • アルツハイマー病および関連認知症(ADRD)は公衆衛生上の課題であり、正確な認知機能障害(CI)診断が必要とされている。;電子カルテ(EHR)には、構造化されていない臨床記録内に貴重なCIデータが含まれている。;GPT-4oのような大規模言語モデル(LLM)は、CIの特定とステージングのためのEHRデータの分析に可能性を提供している。

研究 の 目的:

  • 電子カルテデータを用いたCIステージングおよび自動臨床認知症評価(CDR)スコアリングのためのGPT-4o搭載フレームワークを開発・評価すること。;CI分類におけるGPT-4oフレームワークと従来の自然言語処理および埋め込みベースのモデルのパフォーマンスを比較すること。

主な方法:

  • 1002人のメディケア患者を対象に、データクエリ、特徴抽出、分類を含むCIステージングのためのGPT-4oフレームワークを開発した。;GPT-4oは、信頼度レベルとともに、マルチノート要約を生成し、順序CI分類を実行した。;自動CDRスコアリングは、構造化された回答テンプレート、検索拡張生成(RAG)、および信頼度レベルを持つCDRドメインカウントを使用して達成された。

主要な成果:

  • GPT-4oフレームワークは、CIステージングにおいて高い精度を示した(加重コエンのκ=0.95、スピアマン相関=0.93)。;高信頼度の予測において、従来の特徴抽出および埋め込みベースのモデルよりも優れたパフォーマンスを示した。;ドメインカウントを用いた自動CDRスコアリングは、高い精度を達成した(加重コエンのκ=0.83)。

結論:

  • GPT-4oフレームワークは、認知症診断における自動チャートレビューに大きな可能性を示しており、既存のモデルを凌駕している。;臨床展開には、誤分類のリスクを軽減し、安全性を確保するために、人間参加型のアプローチが必要である。;このハイブリッドAI-人間モデルは、AIの診断能力と解釈可能性およびリスク管理のバランスをとる。
