概括
维生素D不足增加了帕克利塔塞尔化学疗法诱导的周围神经病变 (CIPN) 的风险. 这项研究验证了维生素D不足作为CIPN的预测生物标志物,表明有针对性的补充的潜力.
科学领域:
- 在瘤学瘤学.
- 临床药理学 临床药理学
- 营养科学 营养科学
背景情况:
- 以前的研究表明,维生素D不足与与帕克利塔塞尔治疗相关的化疗诱导的周围神经病变 (CIPN) 风险增加之间存在潜在的联系.
- 化疗诱导的周围神经病变是一种显著的剂量限制性毒性,可以损害癌症患者的生活质量.
研究的目的:
- 为了验证维生素D缺乏症作为化学疗法诱导的周围神经病变 (CIPN) 的预测风险因素,在接受帕克利塔塞尔化疗的患者中.
- 调查治疗前维生素D水平与严重感官神经病变的发生率之间的关联.
主要方法:
- 利用了来自前性第三阶段SWOG S0221试验的数据和血清样本,该试验涉及接受帕克利塔塞尔治疗的早期乳腺癌患者.
- 量化预处理25-基维生素D水平使用液体染色学-并联质谱法.
- 采用多重逻辑回归来评估维生素D不足 (≤20 ng/mL) 与等级≥3感官CIPN之间的关联,调整为共变量. 用小鼠模型来评估维生素D缺乏对过敏症的直接影响.
主要成果:
- 在1191名分析患者中,有33.3%的患者在治疗前出现维生素D缺乏症,其中16.4%的患者患有≥3级CIPN.
- 患有维生素D缺乏症的患者表现出明显更高的CIPN等级≥3的发生率 (20.7%对比14.2%;P=.005).
- 在调整了年龄和帕克利塔塞尔治疗方案 (调整的OR,1.65;P=.003) 之后,这种关联仍然显著,而缺乏维生素D的饮食使小鼠对帕克利塔塞尔诱导的过敏敏感.
结论:
- 治疗前的维生素D缺乏被确定为第一个被验证的,潜在的可修改的帕克利塔塞尔诱导的外围神经病变的预测生物标志物.
- 这些发现支持了前性试验的必要性,以评估维生素D补充剂在预防CIPN和改善各种癌症类型的治疗结果方面的有效性.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
14
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care
11
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Peripheral Artery Disease I: Introduction
9
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs but also impacts other areas, such as the arms, thereby impairing overall circulation and organ function.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty deposits inside the arterial...
