Chronic Kidney Disease II: Clinical Manifestations

516
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

295
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

358
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

430
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...

647
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

433
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
  • 神経精神医学
  • 老年医学

背景:

  • 無関心と抑うつは、神経認知障害(NCD)において頻繁に併存する。
  • 微小血管障害のマーカーである白質高信号(WMH)は、個別に無関心および抑うつと関連している。
  • これらの併存症状の空間的分布と性別特異的なパターン、およびそれらとWMHとの関係については、理解が限られている。

研究 の 目的:

  • NCD患者における併存する無関心と抑うつ(A+D)と白質高信号(WMH)の重症度との関連を調査すること。
  • 無関心、抑うつ、およびWMHの関係における性別特異的な違いを検討すること。

主な方法:

  • 様々なNCDを有する803人の参加者からなるCOMPASS-NDコホートの縦断的データが解析された。
  • 参加者は、無関心のみ(AO)、抑うつ症状のみ(DO)、A+D、無関心も抑うつもない(NAD)の4つのグループに分類された。
  • WMHの重症度は、脳室周囲(PV)および皮質下(SC)領域におけるFazekasスケールを用いて評価された。;順序回帰分析により群間差が検討され、性別特異的パターンについても個別の解析が行われた。

主要な成果:

  • 併存する無関心と抑うつ(A+D)は、脳室周囲白質高信号(PVWMH)の重症度(β=0.508, p=0.01)と有意に関連していたが、皮質下白質高信号(SCWMH)とは関連がなかった。;無関心のみ(AO)または抑うつ症状のみ(DO)は、PVWMHまたはSCWMHとは関連がなかった。;性別特異的解析では、A+Dを有する男性は有意に高いPVWMH重症度を示した(β=0.765, p=0.002)が、女性では有意な関連は見られなかった。

結論:

  • 本研究では、併存する無関心と抑うつ(A+D)と脳室周囲白質高信号(PVWMH)との間に正の関連が見られ、特に男性において顕著であった。
  • WMHの重症度と、孤立した無関心または抑うつ症状との間には関連は見られず、併存症状を有する女性においても同様であった。
  • 本研究の結果は、NCDにおけるWMHと併存する無関心/抑うつとの関係を理解する上で、領域別および性別特異的な解析の重要性を強調しており、治療への応用が期待される。
