Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

農薬DDT代謝物のDDEの出生前曝露は、アルツハイマー病の主要なバイオマーカーの低下と中年期の認知機能低下に関連していました。これは、DDT/DDE曝露がアルツハイマー病および関連認知症(ADRD)のリスクを高める可能性を示唆しています。

科学分野:

  • 環境健康; 神経科学; 毒物学

背景:

  • 環境への曝露は、アルツハイマー病および関連認知症(ADRD)のリスク因子としてますます認識されています。; 以前の研究では、高濃度の血清DDE(持続性DDT代謝物)がアルツハイマー病のリスク増加および認知機能低下と関連していることが示されました。; 動物実験では、DDT/DDEが認知機能を低下させ、アミロイド病理を増加させることが示されており、これは血漿Aβ 42/40比の低下によって示されます。

研究 の 目的:

  • 出生前のDDE曝露がヒトの血漿アミロイドベータ(Aβ)レベルおよび認知機能に及ぼす影響を調査すること。; 出生前のDDE曝露と中年期の認知パフォーマンスおよびAβ 42/40比との関連を評価すること。

主な方法:

  • 1959年から1963年のChild Health and Development Studies(CHDS)妊娠コホートのデータを利用しました。; 179人の参加者において、数字記号テスト(DSST)を用いて中年期の認知機能を評価し、血漿Aβ 42/40比を測定しました。; アーカイブされた母体血清中の出生前p,p'-DDEレベルを測定し、一般化線形回帰モデルを用いて関連を分析しました。

主要な成果:

  • 出生前のp,p'-DDEレベルは、中年期の血漿Aβ 42/40比の低下と有意に関連していました(β = -0.37、p = 0.03)。; 出生前のp,p'-DDEレベルが高いほど、中年期のDSSTにおけるパフォーマンスの低下と相関していました(β = -0.020、p = 0.02)。; これらの関連は、共変量を調整した後も頑健でした。

結論:

  • p,p'-DDEの出生前曝露は、中年期のAβ 42/40レベルの変化および認知機能の低下と関連しています。; DDT/DDE曝露が高い集団を特定することは、ADRDのリスクが高い個人を特定するのに役立つ可能性があります。; ADRD進行のリスクがある個人に対して、早期介入および予防戦略を開発することができます。
