- クロルヘキシジングルコナートマウスウォッシュを1年間毎日3回使用した57人のCKD患者を含む前向きな研究.
- S. mutansのコロニー形成単位 (CFU) の変化を唾液とタンパク質尿のレベルでモニタリングする.
- 時間の経過とともに,S. mutans数とタンパク質尿との関連を分析する.
主要な成果:
- ベースラインより高いS. mutans CFU (≥10^3/mL) は,タンパク質尿とS. mutansのレベルが時間とともに増加したとの相関関係があります.
- 12ヶ月間マウスウォッシュを使用した後に,S. mutansのカウントとプロテイン尿の両方の有意な減少が観察されました.
- 低S. mutans数 (<10^3 CFU/mL) の患者は,12ヶ月後,タンパク質尿 <0.3 g/gのクレアチニンの割合が著しく高かった.
結論:
- 経口でのS. mutans数とCKD患者におけるタンパク質尿との間に潜在的な関連性がある.

Chronic Kidney Disease I: Introduction
766
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease II: Clinical Manifestations
683
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...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
