- 这项研究使用NIH工具箱电机电池 (NIHTB-MB) 调查了种族和诊断群体之间的运动性能差异.
研究的目的:
- 为了检查黑人和白人老年人之间运动性能的种族差异.
- 在正常认知 (NC),aMCI和DAT诊断组中评估运动性能.
- 为了测试黑人运动表现较差的假设和带有认知障碍的线性运动衰退.
主要方法:
- 来自ARMADA研究的557名老年人 (65至99岁) 完成了NIHTB-MB评估.
- 多重线性回归分析了NC参与者的种族差异 (控制年龄,性别).
- 在ANCOVA和后期测试中,研究了诊断组差异 (NC,aMCI,DAT).
主要成果:

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...
