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 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 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:

  • 神経科学; 認知心理学; 医療技術

背景:

  • アルツハイマー病（AD）の新たなモノクローナル抗体治療法には、軽度認知障害（MCI）の早期特定が必要である。デジタルTrail Making Test-Part B（dTMT-B）の新しい指標は、MCIと健常認知（NC）を区別する上で有望である。

研究 の 目的:

  • 軽度認知障害（MCI）と健常者（NC）を区別する上での短縮版dTMT-Bの有効性を評価する。短縮版dTMT-Bのパフォーマンスと従来の神経心理学的検査との関係を探る。

主な方法:

  • テストの最初の半分に焦点を当てた短縮版dTMT-Bを開発した。MCIまたはNCに分類された58人の記憶クリニック患者からデータを収集した。ヒット持続時間、距離、速度のプロセス指標を分析した。

主要な成果:

  • MCI患者はNC患者と比較してヒット持続時間が長かった（p < 0.004）。より長いヒット持続時間は、注意、ワーキングメモリ、エピソード記憶検査でのパフォーマンス低下と相関していた。総距離またはペンのストローク速度に有意な差は見られなかった。

結論:

  • 短縮版デジタルTrail Making Test-Part Bは、認知評価のための新しいプロセスベースの指標を提供する。この短縮版は、初期の認知障害のスクリーニングのための多用途なツールを提供する。
