まとめ
コンピュータ支援検出 (CADe) は,アデノマ検出率 (ADR) を改善します. しかし,警戒状態の疲労は,その日の後半にCADeの有効性を低下させ,ADRの増加を減少させる可能性があります.
科学分野:
- 胃腸内科 胃腸内科
- メディカルイマージング (医学イメージング)
- エンドスコピーは,内視鏡検査です.
背景:
- コンピュータ支援検出 (CADe) システムは,大腸内視鏡検査中にアデノマ検出率 (ADR) を向上させることを目的としています.
- 継続的なCADeの使用による潜在的警戒疲労は,時間の経過とともに有効性を低下させる可能性があります.
- ADRに対する警戒疲労の影響を理解することは,CADeの実装を最適化するために不可欠です.
研究 の 目的:
- 大腸内視鏡検査中にCADeを使用すると,警戒疲労が発生するかどうかを調査する.
- 覚醒疲労が,エンドスコピストの日常スケジュール全体でADRに影響を及ぼすかを決定するために.
- 実用的な環境でCADeの実用的な効果を評価する.
主な方法:
- 1,700回のコロノスコピー (880回のCADe,820回のCADeなし) の将来的に収集されたコホートの二次分析.
- 大腸内視鏡検査は,内視鏡医の日常スケジュールの順序に基づいて分析されました.
- プライマリアウトカム:離脱時間 (WT) に調整されたADR;二次アウトカム:アデノマによる結腸鏡検査 (APC),日の時間によるADR.
主要な成果:
- CADeは,最初の3つの処置でADRを大幅に増加させました (49.9%),無補助処置 (39.4%) に比べて.
- CADeアシストされた処置におけるADRは,後期の症例 (39.9%) で減少し,無助の手術 (40.9%) よりも利益を示さなかった.
- CADeによるAdenomas per colonoscopy (APC) の増加は,早期に有意であったが,後の処置では消失し,潜在的な警戒疲労による有効性の低下を示唆した.
結論:
- CADeは最初はADRを高めるが,その有効性は後日コロノスコピーで減少する.
- 観察されたADRの減少は,エンドスコピストの警戒疲労がCADeプロンプトに対する応答性を制限することを示唆しています.
- CADeアラート戦略の最適化は,全結腸内視鏡検査手順リストを通じてその利点を維持するために必要かもしれません.

Fatigue
861
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Endoscopic Procedures II: Colonoscopy
773
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Muscle Recovery and Fatigue
4.3K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Fatigue Strength of Concrete
578
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
439
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Detection of Gross Error: The Q Test
7.1K
When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...
