Artificial Intelligence for Computer Vision in Surgery: A Call for Developing Reporting Guidelines

Advances in computing power and the availability of digital data have led to significant progress in artificial intelligence (AI) algorithms. As a result, novel and innovative applications of AI in healthcare continue to surface both in the scientific community and the lay press at a rapid pace. AI is the field of computer science that focuses on the development of algorithms that enable high-level and rational response, interaction, and advanced cognitive and perceptual functions by machines. One area of AI that has particularly bourgeoned over the last decade is computer vision (CV)— an interdisciplinary scientific field that deals with how computers can gain a high-level understanding of digital images or videos and the ability to perform functions, such as object identification and tracking and scene recognition1. Various fields in medicine have had significant success in the development of AI models capable of performing a variety of diagnostic functions using CV (e.g., identifying abnormalities in diagnostic radiology, identifying malignant skin lesions, and interpreting electrocardiograms), and there is potential for similar success in procedural specialties such as surgery. Clinicians and innovators alike have sought to develop AI algorithms capable of improving our ability to provide therapeutic interventions, such as with real-time decision-support and computer-assisted surgery. 计算能力的进步和数字数据的可用性导致了人工智能(AI)算法的重大进展。因此,人工智能在医疗保健领域的新颖和创新的应用继续以很快的速度出现在科学界和非专业媒体上。人工智能是计算机科学的一个领域,其重点是开发算法,使机器能够做出高水平的理性反应、互动以及高级认知和感知功能。在过去十年里,人工智能的一个领域特别蓬勃发展,那就是计算机视觉(CV)–这是一个跨学科的科学领域,涉及到计算机如何获得对数字图像或视频的高层次理解,以及执行功能的能力,如物体识别和跟踪以及场景识别1。医学的各个领域在开发能够使用CV执行各种诊断功能的人工智能模型方面取得了重大成功(例如,在诊断放射学中识别异常,识别恶性皮肤病变,以及解释心电图),并且有可能在外科等程序性专业领域取得类似的成功。临床医生和创新者都在寻求开发能够提高我们提供治疗性干预能力的人工智能算法,如实时决策支持和计算机辅助手术。

新冠复阳的猜想

最近临近春节,COVID-19疫情有了一些反弹。

无论是海外还是本土,都有一些病例是原本确诊的患者,经治疗已康复并经过一段时间的隔离,但是少数还是有复阳的。目前病毒在人体内的定植部位和过程都不清楚,这其实对鼻咽检测的结果提出了挑战,不过没有更适合的大规模低成本的检测方式,也只能先这样应对,北京部分地区还有采用肛门拭子采样检测的。虽然是呼吸感染病毒,但最早可能通过粘膜传播的发现已经提示飞沫可能只是病毒的最便捷传染方式而已,其实只要能穿透生物屏障,即可。而在人体内多个部位定植的可能,说明即便治疗康复的患者,可能因为没有有效的杀灭病毒的治疗手段,在体内仍可能残留定植的病毒,成为未来可能的传染源。所谓的复阳,其实是没有将体内的病毒彻底清除掉。
