背景情况:
- 慢性睡眠障碍导致神经炎症,星细胞功能障碍和神经退行.
- 状纤维酸蛋白 (GFAP) 是一种与阿尔茨海默病 (AD) 睡眠-清醒干扰相关的天体细胞激活标志物.
- 大脑微型血流 (CMB),表明大脑小血管疾病 (CSVD),也会导致睡眠障碍,但它们与GFAP和跨认知阶段的睡眠相互作用尚不清楚.
研究的目的:
- 调查血GFAP,CMB和认知不受损 (CU) 和认知受损 (CI) 个体的睡眠障碍之间的联系.
- 探索这些因素在认知功能的不同阶段如何不同.
主要方法:

- 被归类为CU或CI (包括轻度认知障碍和轻度AD) 的参与者.
- 评估了血GFAP,APOE ε4状态,睡眠质量,以及对CSVD标记物 (CMBs) 的脑成像. 使用ANOVA,相关性和回归分析了相关性.
主要成果:
- 在CU个体中,更高的GFAP与睡眠不良和更长的睡眠延迟的可能性增加相关.
- 在CI患者中,更高的GFAP与睡眠不良和更高的睡眠效率的可能性降低有关.

Chronic Kidney Disease II: Clinical Manifestations
516
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...

Coronary Artery Disease III: Clinical Manifestations
295
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 II: Clinical Features of Infective Endocarditis
358
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 III: Clinical Manifestations
430
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...

Hypertension III: Clinical Manifestations and Diagnostic Studies
433
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...
