まとめ
微細粒子物質 (PM2.5) に短期間の曝露は,結核 (TB) の発生率の増加と関連しています. 高齢者,女性,農村部住民などの脆弱なグループは,特に寒い時期に,より高いリスクに直面しています.
科学分野:
- 環境疫学環境疫学について
- 公衆衛生は公衆衛生である.
- 空間分析とは,空間分析のことです.
背景:
- 結核 (TB) は,依然として世界的な感染症の脅威である.
- 短期的な微細粒子物質 (PM2.5) 曝露と,粒子の空間レベルで結核の発生率との関連に関する証拠は限られている.
研究 の 目的:
- 短期的なPM2.5曝露と中国の济南で活発な結核発症の間の路面レベルの関連性を調査する.
- 高リスクサブグループと,PM2.5が結核発生率に与える影響の季節的変動を特定する.
主な方法:
- エクストリーム・グラデント・ブースト (XGBoost) モデルとGISを用いて推定された,利用された1日1日のストリートレベルのPM2.5濃度.
- 8,291件のTB症例 (2015-2019) の曝露-反応関係を定量化するために,ベイジアン階層的時空モデルを使用した.
- 年齢,性別,季節,居住地による層別分析を行いました.
主要な成果:
- 3日間の遅れでPM2.5が10μg/m3増加すると,TBの発生率が2%増加した (IRR=1.02,95%CI:1.01-1.03).
- 顕著な効果は6日間の遅れまで続いた (IRR=1.01,95%CI:1.00-1.02).
- 高齢者 (≥65歳),女性,農村部住民,寒い季節 (11月~4月) でリスクが高いことが観察されました.
結論:
- 短期的なPM2.5曝露は,結核発症の重要なリスク因子です.
- 公共衛生の介入は,高リスクサブグループを保護し,寒い季節の汚染制御を実施することを優先すべきである.
- 調査結果は,大気汚染に関連した結核の負担を軽減するためのターゲットを絞った戦略の必要性を強調しています.

Classifying Matter by State
105.0K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.

What is Matter?
104.0K
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...

The Atomic Theory of Matter
130.8K
The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Fineness of Cement
548
The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.
