まとめ
過剰活動性膀 (OAB) は,体内の複数の部位,特に泌尿器系における微生物群の明確な変化と関連しています. これらのシフトは,有益なバクテリアの減少と他のバクテリアの増加を伴い,広範囲にわたるディスバイオシスを示唆しています.
科学分野:
- マイクロバイオームの研究
- 泌尿器科 泌尿器科とは
- 泌尿器生殖器医学とは
背景:
- 膀はもはや不妊とは考えられず,現在では定住する尿道微生物群が認められている.
- 過活動性膀 (OAB) は尿道不活性症と関連しているが,膀微生物の起源と関連性は不明である.
研究 の 目的:
- OABの女性における尿道微生物群のプロフィールを,健康な対照群と比較する.
- 泌尿器および他の微生物群 (陰道,尿道,口腔,便) の関係を評価する.
- 微生物の重複を分析することによって,潜在的な微生物のコロニー化経路を特定します.
主な方法:
- 50人のOABと49人の対照群の女性を対象とした横断研究.
- 尿,尿道,陰道,口腔,便のサンプルを 16S rRNA 遺伝子配列化.
- Rパッケージを用いた多様性,多様性の多様性,微生物の重複の分析.
主要な成果:
- OAB症例は,すべてのサイトで尿道/陰道多様性が高く,ベータ多様性が変化しました.
- OAB尿道にはラクトバシロスが少ないが,バクテロイド,ビフィドバクテリウム,ガーデネレラ,その他が多かった.
- OABの尿道,尿,陰道,口腔では6つの特定の分類が上昇したが,便は上昇しなかった.
結論:
- OABを患っている女性は,特に泌尿器系において,ラクトバチルスの枯渇と他の taxaの濃縮とともに,多部位ディスバイオシスを示します.
- 微生物の重複は,便の微生物群とは異なる泌尿器官の関係性を示唆しています.
- これらの発見は,OABの微生物群の変化と,標的型戦略に関する縦断的な研究の必要性を強調しています.

01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:21Nursing Assessment of the Genitourinary System I: Health History
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...
01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:30Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
01:17Urinary Tract Infection IV: Nursing Management
In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs like...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
