- 生物标志物 生物标志物
- 认知健康 认知健康
背景情况:
- 轻度认知障碍 (MCI) 涉及大脑低和神经炎症的相互关联过程.
- 这些过程可以产生氧化应激和炎症的循环,导致认知能力下降.
- 独特的认知和血生物标志物概况可以区分MCI的血管和炎症原因.
研究的目的:
- 在东南亚队列中调查不同的认知和血生物标志物概况.
- 在MCI中区分血管 (低输血占主导地位) 和炎症驱动的认知障碍.
- 探索MCI中低输液和神经炎症之间的相互作用.
主要方法:
- 患有MCI的参与者被分为低输液主导 (P+),神经炎症主导 (I+) 和控制 (p-) 组,使用MRI和状纤维酸蛋白 (GFAP) 水平.
- 在这三个组中,认知表现和血生物标志物概况进行了比较.
- 调解分析被用来检查hyperfusion和神经炎症之间的相互作用.
主要成果:
- P+组显示神经纤维光链 (NfL) 水平升高.
- 与P+组相比,I+组的NfL较高,Oligomeric Amyloid-Beta (OAB) 高,Amyloid-Beta 42/40 (Aβ42/40) 比率降低,全球认知表现 (VCAT) 较低.
- 神经炎症调解了低 perfusion 和 NfL 之间的联系,而减少 perfusion 则调解了神经炎症对认知衰退的影响.

01:24Chronic Kidney Disease II: Clinical Manifestations
520
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...

299
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

01:30Hypertension III: Clinical Manifestations and Diagnostic Studies
437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
