- エピデミオロジー
背景:
- 胃食道逆流症 (GERD) は,原因がはっきりしない一般的な胃腸疾患です.
- 環境空気の汚染とGERDの発生の間の関連については,さらなる調査が必要である.
研究 の 目的:
- 環境空気の汚染物質への長期的曝露とGERDの発生リスクとの関連を調査する.
- 特定の大気汚染物質と,GERDリスクの増大に関連する脆弱な集団を特定する.
主な方法:
- 英国バイオバンクデータベースを利用したコホート研究.
- PM10,PM2.5-10,PM2.5,NOx,NO2の年間平均濃度は,土地使用回帰モデルを用いて評価された.
- 空気汚染物質の曝露に関連するGERD発生リスクを推定するために,コックスの比例的ハザード回帰法を使用した.
主要な成果:
- 14年間に289,387人の参加者の間で32,413人のGERD症例が診断されました.
- PM10,PM2. 5-10,PM2. 5,NOx,およびNOへの曝露の増加は,より高いGERD発生リスクと関連していました.
- 特に食道炎のないGERDでは線形的な暴露反応が観察され,女性,中年,肥満の個人がより脆弱であった.

01:29Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
493
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

2.8K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

01:21Barrett Esophagus-I: Introduction
201
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

01:30Peptic Ulcer Disease I: Introduction
287
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
