背景情况:
- 与PSEN1-E280A变体相关的自体主导阿尔茨海默病 (ADAD) 早期影响个人.
- 步行速度 (GS) 是潜在的认知衰退的早期指标,年轻人群体的肌肉功能研究越来越多.
研究的目的:
- 调查哥伦比亚PSEN1-E280A自体主导阿尔茨海默病 (ADAD) 队列中步行速度 (GS) 和认知功能之间的关系.
- 探索步行速度作为潜在的早期标志物认知能力下降的年轻人面临ADAD风险.
主要方法:
- 研究了来自PSEN1-E280AADAD家族的134个人 (66名载体,68名非载体).
- 用功能评估分期 (FAST) 尺度和迷你精神状态检查 (MMSE) 评估认知状态.
- 肌肉功能通过单任务步行速度 (GS) 进行评估,并进行单变量和多变量分析.
主要成果:
- 在PSEN1-E280A载体和非载体之间没有发现GS的显著差异.
- 认知障碍的个体与认知正常的个体相比,GS显著较慢 (1.37 m/s vs 1.63 m/s).
- 在GS和MMSE得分之间观察到微弱的正相关性,特别是在受损组.

Chronic 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...

Coronary Artery Disease III: Clinical Manifestations
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 III: Clinical Manifestations
436
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
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...
