まとめ
術後早期の血球濃度値は,総関節整形手術 (THA) の輸血需要の重要な予測因子です. また,再手術は輸血リスクを高め,カップの傾きは予測価値が最小限にある.
科学分野:
- 整形外科 整形外科
- アネステシオロジー アネステシオロジー
- 輸血医学とは
背景:
- 術後の輸血管理は,総股関節整形術 (THA) で非常に重要です.
- 輸血予測要因を特定することで,患者の安全性と血液管理戦略を最適化できます.
- この研究では,THAの輸血に関連した独立した手術後の要因を特定しようとしました.
研究 の 目的:
- 選択的プライマリー・トータル・ヒップ・アルトプラスティ (THA) での輸血の独立した手術前予測要因を特定する.
- 輸血のためのカップの傾きと48時間ヘマトクリットの予測値を評価するために.
- 輸血リスクの階層化のための組合せ決定規則の有用性を評価する.
主な方法:
- 選択的なプライマリTHA手順 (2016-2023) の遡及的分析.
- 既定の式を用いて,総および隠された血流の計算.
- 多変数ロジスティック回帰および受容器操作特性 (ROC) 分析により,輸血予測因子を特定します.
主要な成果:
- カップの傾き (OR=0.89),48時間ヘマトクリット (OR ≈5.17×10−48) および再手術 (OR=13.19) は,輸血と独立して関連していました.
- 多変量モデルでは,優れた差別性 (AUC=0.931) を示した.
- 48時間ヘマトクリットは強い予測値 (AUC=0.817) で,値<0.28 L/L;カップの傾きは無視できる予測値 (AUC=0.393) でした.
結論:
- 早期の術後の血球濃度 (hematocrit) は,一次性THA.の輸血リスクの強固で実行可能なマーカーです.
- カップの傾きは,直接の輸血リスクではなく,外科的テクニックを反映しています.
- 再手術は,手術前後の複雑性を暗示する;輸血戦略の傾きベースの値よりも,血圧値に基づく評価が推奨される.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Factors Affecting Solubility
37.3K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Transcription Elongation Factors
14.1K
Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...
