概括
人工智能心电图 (AI-ECG) 可以预测移植 (KTx) 后新出现的心房动 (AF). 高风险分数可以识别需要更密切监测和干预的患者,以获得更好的结果.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 心脏病学 心脏病学
- 人工智能的人工智能
背景情况:
- 接受移植 (KTx) 的人经常患上心房动 (AF),导致结果较差.
- 人工智能心电图 (AI-ECG) 对KTx患者新发性AF的预测价值尚未得到充分证实.
研究的目的:
- 评估移植前AI-ECG算法的预后效用,以预测KTx受体中发生的AF.
- 评估AI-ECG衍生的风险得分与移植后结果的关联,包括全移植失败和死亡率.
主要方法:
- 对6246名KTx接受者没有先前存在的AF进行了回顾性分析,利用2011-2021年的移植前心电图数据.
- 一个经过验证的AI-ECG算法估计了AF的概率;根据最佳切断分数,患者被分为高风险和低风险组.
- 风险组之间的新发性AF发病率,全移植失败和死亡率的比较.
主要成果:
- 一个AI-ECG的AF概率≥5%被确定为高风险的最佳切线 (灵敏度72%,特异性62%).
- 高风险AI-ECG得分与30天,3年,5年后KTx新发AF发病率的增加有显著的相关性.

Predicting Reaction Outcomes
10.9K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Kidney Transplant I: Introduction
481
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Amyloid Fibrils
12.0K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Kidney Transplant II: Surgical Procedure
419
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Chronic Kidney Disease II: Clinical Manifestations
664
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...

Prevalence and Incidence
1.9K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
