まとめ
大規模な外科手術は,感染症につながる可能性のある免疫の変化を引き起こします. 手術後の免疫機能のモニタリングは,感染リスクを予測し,治療を導くのに役立ちます.
科学分野:
- 免疫学 免疫学とは
- 外科腫瘍学外科腫瘍学
- クリティカルケア・メディシン
背景:
- 大規模な手術は,炎症と抑制を含む複雑な免疫反応を誘発します.
- これらの免疫系の変化は,手術後の感染症の合併症のリスクの増加と関連しています.
研究 の 目的:
- 術後の免疫活性化/抑制パターンと術後の感染症の発生との関連を調査する.
- 手術後の感染症合併症を予測する免疫マーカーを特定する.
主な方法:
- 様々な手術を受けた487人の患者を対象とした6つの前向きな研究のプール分析.
- 免疫モニタリングには,血のサイトカインレベル (IL-6,IL-10),ex vivoサイトカイン産生 (TNF,IL-1β),およびプロテオミックプロファイリングが含まれていました.
- 評価された臨床的アウトカムには,手術後の感染,痛み,回復の質が含まれる.
主要な成果:
- 手術により,早期のIL-6とIL-10の増加,続いて抑制されたTNFとIL-1βの生産が起こりました.
- 免疫抑制は,乳房手術患者と比較して,大腸直腸手術患者でより長く持続しました.
- 術後感染症の患者は,術後1日により高いIL-6/TNFを示し,術後3日にEX-VIVOTNFを減少させた.
結論:
- 手術による傷害は早期の炎症と先天性免疫抑制の遅延を引き起こす.
- 術後3日までに先天性免疫機能の回復が遅れた場合,感染のリスクが高くなります.
- 定期手術による免疫プロフィーリングは,早期のリスク分層化に役立ち,免疫調節戦略を伝えることができます.

Factors Affecting the Risk of Infection
14.0K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
