概括
人工智能辅助的胸部X射线查显示了对菲律宾结核病的高度敏感性,但需要仔细的值校准才能在现实世界中得到最佳应用.
科学领域:
- 医学成像
- 医疗保健中的人工智能
- 公共卫生
背景情况:
- 菲律宾面临着高结核病负担,需要有效的护理点查解决方案.
- 使用胸部X射线深度学习的计算机辅助检测 (AI-CAD) 是系统发现结核病例的有希望的方法.
研究的目的:
- 评估AI-CAD在菲律宾的结核病查中的实际性能.
- 将AI-CAD整合到国家结核病消除计划中的精细化.
主要方法:
- 在菲律宾四个地区 (2021年5月至2024年3月) 进行5 740名 (≥15岁) 个体的CXR和分子快速诊断 (mWRD) 测试结果的回顾性分析.
- 评估AI-CAD的诊断准确性,使用固定异常值,使用mWRD作为参考标准.
- 由于数据不平衡,采用了精度回忆 (PRC) 和接收器运行特征 (ROC) 曲线;对于部分验证的情况,采用了"伪敏感性"和"伪特异性".
主要成果:
- 在0. 5的异常值下,AI- CAD表现出高伪敏感性 (95. 6%),但低伪特异性 (28. 1%) 和正预测值 (PPV) (18. 4%).
- 在ROC曲线下的面积为0.820;在PRC曲线下的面积为0.489.
- 将门提高到0.68提高了测试节省率 (42%),但增加了遗漏病例 (10%);性能因人口因素和环境而异.
结论:
- AI-CAD有可能扩大结核病查并推动菲律宾的结核病消除工作.
- 根据当地资源可用性,结核病发病率和计划目标进行准至关重要.
- 在资源有限的环境中,ROC和PRC图片对于评估模型性能和成本效益非常有价值.

Pulmonary Tuberculosis IV
204
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis I
324
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
