科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 跨文化研究跨文化研究.
背景情况:
- 阿尔茨海默氏症痴呆症 (ADD) 诊断依赖于认知衰退,但目前的评估缺乏准确性,受到文化影响.
- 当生物标志物不可用或与临床发现相冲突时,临床判断至关重要.
- 诊断工具的跨文化协调是全球准确性所必需的.
研究的目的:
- 评估视觉短期记忆结合测试 (VSTMBT) 和拉丁美洲其他认知评估的跨文化有效性.
- 确定这些测试是否可以在不同文化背景下可靠地检测阿尔茨海默氏症痴呆症 (ADD).
主要方法:
- 从阿根廷,巴西,智利,哥伦比亚,墨西哥和秘鲁招募了426名ADD患者和869名健康对照.
- 进行了包括VSTMBT,工艺故事21测试 (CS21T) 和本森复杂图形测试 (CBFT) 在内的综合性协议.
- 采用通用线性模型 (GLM) 和接收器操作特征 (ROC) 分析来评估组差异和分类准确性,控制混因素.
主要成果:
- VSTMBT在ADD患者中显示出显著的缺陷,特别是在形状-颜色结合中.
- 这三种测试 (VSTMBT,CS21T,CBFT) 均显示,与不同国家的健康对照人群相比,ADD个体的认知缺陷显著.
- 结合三个测试的综合得分显示,在研究的拉丁美洲国家中,ADD检测的分类准确度高 (AUC>0.78).
结论:
- VSTMBT,CS21T和CBFT是评估拉丁美洲不同人口中ADD的可靠工具.
- 尽管观察到的变化,这些测试始终确定了与ADD相关的显著缺陷,独立于混因素.
- 这些发现支持拉丁美洲VSTMBT的跨文化有效性,扩展了欧洲国家的先前发现.

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 (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...

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...
