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 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 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...

科学分野:

  • 神経病理学
  • 精神神経医学
  • 老年医学

背景:

  • LATE-NC(辺縁系優位の加齢性TDP-43脳症の神経病理学的変化)は、アルツハイマー病(AD)、レビー小体病(LBD)、および血管性病理と併存することがよくあります。
  • AD/LATE-NCにおける神経精神症状はますます研究されていますが、混合AD/LBDおよびLBDにおけるそれらの影響は十分に調査されていません。

研究 の 目的:

  • AD、LBD、および混合AD/LBDを有する個人で、LATE-NCの有無にかかわらず、神経精神症状プロファイルを調査および比較すること。
  • これらの患者群における神経精神症状の重症度および進行に対するLATE-NCの影響を分析すること。

主な方法:

  • UBCH-CARDデータベースからの剖検で確認された症例の後ろ向きコホート研究。
  • 年齢および神経病理に基づいて、LATE-NC陽性(LATE+)症例42例とLATE-NC陰性(LATE-)症例38例をマッチング。
  • 神経精神症状質問票(NPI-Q)を使用して神経精神症状を評価し、線形混合効果モデルを使用して経時的データを分析しました。

主要な成果:

  • LATE+群とLATE-群の間で、神経精神症状の全体的な重症度または経時的な負担に有意な差は見られませんでした。
  • 無関心、幻覚、食欲の変化はLATE+群でより軽度でした。
  • 共存する病理を調整した後でも、幻覚はLATE+群で有意に頻度が低かったです。

結論:

  • LATE-NCは、ADおよび/またはLBDを有する個人の神経精神症状の全体的な負担を悪化させないようです。
  • LATE+群における幻覚頻度の低下は、レビー小体病理に関連する可能性があり、さらなる調査に値します。
  • 症状進行の経時的モデリングは、LATE-NCの影響を完全に理解するためにさらなる分析が必要です。
