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:

  • 神経学
  • 神経科学
  • スポーツ医学

背景:

  • 主観的認知苦情（SCC）は、早期アルツハイマー病および関連認知症の兆候となる可能性があります。
  • 反復性頭部外傷（RHI）は、特に元プロアメリカンフットボール選手において、SCCの増加と関連しています。

研究 の 目的:

  • 多様なRHI曝露を持つ個人における参加者および情報提供者によって報告されたSCCを特徴づけること。
  • SCCと神経心理学的測定値の一致を評価すること。
  • RHI曝露を受けた個人におけるSCCに関連する要因を特定すること。

主な方法:

  • RHI（n=172）および非RHI（n=320）群間でSCC（認知変化指数、BRIEF-Aメタ認知指数）を比較しました。
  • 標準化された神経心理学的テストを使用して記憶および実行機能を評価しました。
  • 回帰モデルを使用して、自己/情報提供者SCCと神経心理学的パフォーマンスとの相関を調査しました。

主要な成果:

  • RHI群は非RHI群よりも有意に高いSCC（MI、CCI）を報告しました。
  • 自己/情報提供者SCCは、非RHI群と比較してRHI群でより強い相関を示しました。
  • SCCはRHI群の客観的認知測定値と関連していましたが、非RHI群では関連性が低かったです。

結論:

  • RHIの設定におけるSCCはより頻繁であり、実際の認知変化を反映している可能性があります。
  • SCCの高い発生率は多因子性であり、神経精神医学的要因の影響を受けている可能性が高いです。
  • SCCとその疾患バイオマーカーとの相関を追跡するには、縦断的研究が必要です。
