Chronic Kidney Disease II: Clinical Manifestations01:24

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 II: Clinical Features of Infective Endocarditis01:25

Endocarditis II: Clinical Features of Infective Endocarditis

364
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 Manifestations01:26

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...

Gastroesophageal Reflux Disease II: Clinical Features and Management01:29

Gastroesophageal Reflux Disease II: Clinical Features and Management

652
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

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...

科学领域:

  • 老年学是指老年学的学科.
  • 认知神经科学 认知神经科学
  • 数字健康数字健康

背景情况:

  • 睡眠和日常压力的个体内变化 (IIV) 是已知的主观认知能力下降的相关因子.
  • 使用生态瞬间评估 (EMA) 和智能手表,情绪,身体活动和主观认知的日常波动之间的IIV之间的关系仍然不太被探索.

研究的目的:

  • 研究由EMA和智能手表测量的可修改风险因素 (体力活动,睡眠,压力,情绪) 与主观认知的日常波动的关系.
  • 评估EMA与智能手表衍生的身体活动和睡眠时间指标之间的一致性.

主要方法:

  • 55名老年人 (认知健康或有轻度认知障碍) 参与了这项研究.
  • 参与者佩戴智能手表30天,并每天通过智能手机完成EMA调查.
  • 收集的数据包括睡眠时间,身体活动 (步骤,运动时间),压力,情绪和主观认知.

主要成果:

  • 睡眠持续时间 (EMA) 的更高IIV与主观认知 (p=.045) 和智能手表睡眠持续时间 (p=.041) 的更高IIV相关.
  • 较高的日常压力 (p=.003) 和较高的情绪IIV (p=.012) 与主观认知的IIV增加有关.
  • 增加体力活动 (EMA运动) 与更高的每日步数 (p<.001) 和主观认知的较低的IIV (p=.037) 有关.

结论:

  • 不一致的睡眠,增加的压力,减少的体力活动和情绪变化与主观认知的日复一日更大的波动有关.
  • 欧洲药物管理局和智能手表的测量结果显示,身体活动和睡眠之间存在一致性.
  • 情绪和睡眠的规律性,以及增加的运动,被强调为认知健康的关键可修改因素,并可能减轻认知衰退.
