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...

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
  • 集中治療医学
  • バイオマーカー

背景:

  • 集中治療室（ICU）生存者は、重症病後の神経変性および認知障害の高いリスクに直面する。
  • 神経変性疾患の特徴である星状細胞反応性は、この文脈で関与しているが、十分に理解されていない。

研究 の 目的:

  • 重症病がICU患者における星状細胞反応性、神経変性、および認知機能に及ぼす影響を調査すること。
  • 星状細胞反応性マーカーと死亡率予測スコアとの関係を探求すること。

主な方法:

  • ICU患者（40歳以上）および健常対照群を募集した。
  • SIMOAを用いて、血漿中のグリア線維性酸性タンパク質（GFAP）および神経線維軽鎖（NfL）を測定した。
  • ミニメンタルステート検査（MMSE）およびモントリオール認知評価（MOCA）を用いて認知機能を評価した。

主要な成果:

  • ICU患者は対照群と比較して有意に高いGFAPおよびNfLレベルを示した。
  • GFAPレベルは、死亡率予測因子である急性生理学的スコアIII（SAPS III）と正の相関を示した。
  • 認知スコア（MMSE、MOCA）は群間で異なったが、GFAPまたはNfLレベルとの相関はなかった。

結論:

  • 重症病は、星状細胞反応性および神経変性マーカーに著しく影響を与える。
  • 星状細胞反応性は、集中治療環境における死亡率予測と関連がある。
  • GFAPおよびNfLは、ICU生存者における神経変性管理のためのバイオマーカーとしてさらなる調査に値する。
