まとめ
ASASの基準は,コロンビアにおける脊椎関節炎 (SpA) の高い感受性を示しているが,いくつかの軸性SPA (axSpA) の症例を誤って分類している. 正確な分類のために,axSpAの入場基準のさらなる評価が必要である.
科学分野:
- リウマトロジ
- 免疫学
- 臨床流行病学
背景:
- 脊椎関節炎 (SpA) の分類には,国際脊椎関節炎評価協会 (ASAS) の基準が標準となっています.
- コロンビアのような 多様な集団における 彼らのパフォーマンスには 検証が必要です
- SpAのサブタイプ (アキシアル SpA - axSpA,ペリフェラル SpA - pSpA) を理解することは,管理に極めて重要です.
研究 の 目的:
- コロンビアの SpA 集団を特徴づけるために
- pSpAに関連する要因を特定する.
- ASASの基準を他の分類 (mNY,ESSG) とリウマチ学者による診断と比較する.
主な方法:
- SpAと診断された461人の患者の横断的な研究.
- 調査,身体検査,画像検査,検査によるデータ収集
- ASAS,ESSG,mNYの基準を用いた分類
主要な成果:
- コホートは主にpSpA (58. 1%) であった.
- axSpAとpSpAの間では,人口統計,症状,イメージングにおいて有意な差異が観察されました.
- ASASの基準では90. 8%の感度を示したが,mNY/ ESSGアンキロージング脊髄炎症例の33%をpSpAとして誤って分類した.
結論:
- コロンビアのSpAコホートは,異なるaxSpAとpSpAの特徴を示しています.
- ASASの基準は高感度だが,xSpAの分類には制限がある.
- ASAS axSpAのエントリー基準の精細化により,分類の精度が向上する可能性があります.

Sputum Studies II: Culture and Sensitivity
580
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

Bias in Epidemiological Studies
671
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Autism Spectrum Disorder
335
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
