概括
肥胖与COVID后病情 (PCC) 患者的大脑结构变化有关. 较高的体重指数 (BMI) 与thalamus灰质体积 (GMV) 的减少以及PCC的炎症标志物的改变相关.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 公共卫生 公共卫生
背景情况:
- 肥胖是严重COVID-19的独立风险因素,与结构性大脑变化有关.
- 后COVID状态 (PCC) 与结构性大脑异常和免疫学变化有关.
- 这项研究调查了肥胖是否导致PCC患者的神经和免疫学差异.
研究的目的:
- 评估肥胖对PCC患者大脑结构变化的贡献.
- 检查PCC中体重指数 (BMI) 和灰质体积 (GMV) 之间的关系.
- 调查PCC中BMI,GMV和免疫标志物之间的关联.
主要方法:
- 分析了61名PCC患者的队列.
- 基于全脑素的形态测量 (VBM) 用于比较灰质体积 (GMV).

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
