Prevalence and Incidence01:08

Prevalence and Incidence

783
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Assessment of the Gastrointestinal System I: Subjective Data

270
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Gastroesophageal Reflux Disease II: Clinical Features and Management

150
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...

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

14.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

科学分野:

  • 遺伝学とゲノミクス
  • 胃腸科と肝臓科
  • 医療におけるデータサイエンス

背景:

  • ギルバート症候群 (GS) は,UGT1A1酵素欠乏によるビリルビンの値上昇によって特徴づけられる一般的な遺伝疾患である.
  • 臨床的症状には,しばしば黄や薬物反応のリスクが含まれますが,疲労や腹痛などの非特異的な症状が頻繁に報告されています.

研究 の 目的:

  • ギルバート症候群の様々な症状と診断トリガーを調べるため
  • GSの初期指標について 電子医療記録を分析する.

主な方法:

  • イギリスのプライマリーケア電子医療記録 (IQVIA医療研究データベース) を利用し,1100万人以上の患者を対象とした.
  • GS診断前の重要な臨床的特徴を特定するために,特徴の選択のための機械学習によるネストされた症例対照設計を使用した.
  • 性別による縦断分析により,診断のトリガーから持続的な症状が区別されました.

主要な成果:

  • イギリスにおけるGSの推定罹患率は10万人に180.4人であり,男性と若い成人の罹患率はより高い.
  • 機械学習は黄,異常な肝機能検査,腹痛,疲労,腸の変化,睡眠障害を 重要な診断テーマとして特定しました
  • 診断前の1年に主に現れる他の特徴とは異なり,腹痛と疲労は診断前の5年間まで一貫して存在していました.

結論:

  • ギルバート症候群の予想と新しい診断のトリガーを特定しました.
  • 持続的な疲労と腹痛は,GSの認識されていない初期症状を表す可能性があります.
  • データを駆動する方法は,他の診断不足の遺伝疾患の早期徴候を特定するのに役立ちます.
