概括
计算机辅助检测 (CADe) 在结肠镜检查的早期改善了腺瘤检测率 (ADR). 然而,警觉疲劳可能会在当天晚些时候降低CADe的有效性,从而减少ADR的增加.
科学领域:
- 胃肠病学 胃肠病学
- 医疗成像医学成像
- 内镜检查是指内镜检查.
背景情况:
- 计算机辅助检测 (CADe) 系统旨在提高结肠镜检查期间腺瘤检测率 (ADR).
- 随着时间的推移,持续使用CADe可能导致潜在的警报疲劳可能会降低其有效性.
- 了解警觉疲劳对ADR的影响对于优化CADe实施至关重要.
研究的目的:
- 为了调查是否发生警觉疲劳与CADe在结肠镜检查期间使用.
- 为了确定警觉疲劳如何影响ADR在整个内镜师的日常时间表.
- 在务实的环境中评估CADe的实际有效性.
主要方法:
- 对预期收集的1,700例结肠镜队列 (880例带有CADe,820例没有) 的二次分析.
- 结肠镜检查是根据内镜师日常时间表中的顺序进行分析的.
- 主要结局:根据禁食时间 (WT) 调整后的ADR;次要结局:每次结肠镜检查 (APC) 的腺瘤,按一天的时间进行ADR.
主要成果:
- 与无辅助手术 (39.4%) 相比,CADe在前三项手术中显著增加了ADR (49.9%).
- 在CADe辅助手术中的ADR在后期病例中下降 (39.9%),与无辅助手术 (40.9%) 相比没有益处.
- 结肠镜一次腺瘤 (APC) 与CADe的增长在早期是显著的,但在随后的手术中消失了,这表明由于潜在的警报疲劳,有效性降低了.
结论:
- CADe最初可以增强ADR,但在晚期结肠镜检查中,它的有效性会降低.
- 观察到的ADR下降表明,内镜师的警觉疲劳可能会限制对CADe提示的响应能力.
- 优化CADe预警策略可能是必要的,以维持其在整个结肠镜程序列表中的好处.

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...
