概括
一个新的AHANDS评分有效预测癌症患者在诊断后两年内缺血性中风风险. 这种工具有助于为这种高风险人群制定有针对性的中风预防策略.
科学领域:
- 在瘤学瘤学.
- 神经学 神经学
- 心血管医学 心血管医学
背景情况:
- 癌症患者面临着显著增加缺血性中风的风险.
- 现有的癌症患者中风风险预测模型缺乏可靠性.
- 迫切需要准确的工具来识别高风险个体,以便及时干预.
研究的目的:
- 开发和验证癌症患者缺血性中风的新型风险预测模型.
- 在癌症诊断后的早期确定与缺血性中风相关的关键临床因素.
- 为了比较新模型的性能与现有的得分,如Khorana得分.
主要方法:
- 开发和外部验证风险预测模型,使用大阪大学医院和大阪国际癌症研究所的大型癌症患者队列.
- 数据包括患者人口统计,病史 (高血压,心房动),中性粒细胞与淋巴细胞的比率,D-二次数水平和癌症阶段.
- 根据以下因素来得出AHANDS评分:年龄≥75岁,高血压,心房动,中性粒细胞与淋巴细胞的比率,D-二次体,以及癌症第四阶段/转移.
主要成果:
- 在发育队列中,AHANDS得分显示出与Khorana得分相比,缺血性中风的歧视优越 (c-统计0.703对0.54).
- 外部验证证实了AHANDS得分的强表现 (c-统计值为0.75).
- 在两年内,缺血性中风发生率在发展队列中为0.61%,在验证队列中为0.31%.
结论:
- AHANDS评分是预测癌症患者缺血性中风风险的可靠和验证的工具.
- 这个模型可以帮助临床医生根据中风风险对癌症患者进行分层.
- AHANDS评分旨在指导在瘤护理中实施个性化中风预防策略.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
377
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Cancer Survival Analysis
634
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
