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:

  • 神经病理学神经病理学
  • 神经精神病学是一种神经精神病学.
  • 老年医学 老年医学

背景情况:

  • 临主导的与年龄相关的TDP-43脑病变神经病理变化 (LATE-NC) 通常与阿尔茨海默氏症 (AD),莱维体病 (LBD) 和血管病理共同发生.
  • 虽然AD/LATE-NC中神经精神症状的研究越来越多,但它们在混合AD/LBD和LBD中的影响仍未得到充分研究.

研究的目的:

  • 调查和比较AD,LBD和混合AD/LBD,有或没有LATE-NC的个体的神经精神病症状概况.
  • 分析LATE-NC对这些患者群体神经精神病症状的严重程度和进展的影响.

主要方法:

  • 来自UBCH-CARD数据库的尸检确认病例的回顾性队列研究.
  • 42个LATE-NC阳性 (LATE+) 病例与38个LATE-NC阴性 (LATE-) 病例的匹配,基于年龄和神经病理.
  • 使用神经精神病 inventory问卷 (NPI-Q) 评估神经精神病症状,并使用线性混合效应模型对纵向数据进行分析.

主要成果:

  • 在LATE+和LATE-组之间,在整体神经精神病症状严重程度或纵向负担方面没有发现显著差异.
  • 在LATE+组中,冷漠,幻觉和食欲变化不那么严重.
  • 幻觉在LATE+组的频率仍然明显低,即使在调整并存的病理之后.

结论:

  • 晚期NC似乎不会加剧AD和/或LBD患者的整体神经精神病症状负担.
  • 在LATE+组的幻觉频率降低需要进一步的研究,可能与勒维体病理学有关.
  • 对症状进展的纵向建模需要进一步分析,以充分理解LATE-NC的影响.
