まとめ
処置前のアルバミン・ビリルビン (ALBI) スコアは,トランスキャセター大動脈弁インプラント (TAVI) の後の死亡率を予測します. より高いALBIスコアは,短期および長期の死亡リスクの増加を示し,患者のリスクの階層化を高めるために使用することを示唆しています.
科学分野:
- 心臓病学 心臓病学
- ゲリアトリック・メディシン (老年医学)
- 医療診断 医療診断
背景:
- トランスキャテータ大動脈弁の埋め込み (TAVI) は,大動脈狭窄の重要な手順です.
- 正確な処置前のリスクの階層化は,TAVIの結果を最適化するために不可欠です.
- 従来のリスクスコアは,TAVI候補者のシステム脆弱性を完全に捉えることはできません.
研究 の 目的:
- 処置前のアルブミン・ビリルビン (ALBI) スコアの予後値を決定するために.
- TAVI.の短期・長期の結果とALBIスコアの関連性を評価する.
- TAVI患者のリスク層分化の改善におけるALBIスコアの潜在的な役割を調査する.
主な方法:
- TAVIを受けた737人の患者の遡及的分析.
- 処置前のALBIスコアに基づいて,患者様を三位に分類する.
- 臨床,エコーカルディオグラフィ,および実験室の特徴の比較,ALBIテリティルの間で.
- カプラン・マイヤーおよびコックス回帰分析を用いた入院および長期的な全因死亡率の評価.
主要な成果:
- ALBIスコアが高くなった三つ目は,併発症の負担の増加,心室機能の低下,炎症マーカーの上昇と相関していた.
- 病院での死亡率は,ALBIの第三種動物 (5.3%から11.8%) で増加した.
- 長期的な死亡率は,より高いALBIスコアで漸進的に上昇し,60ヶ月の生存率は90%~73%であった.
- ALBIスコアは,慢性腎疾患とTAPSEの減少とともに,長期的な死亡率を独立して予測しました.
結論:
- 処置前のALBIスコアは,TAVI後の短期および長期の死亡率の両方の独立した予測指標です.
- ALBIスコアは,従来のリスク評価モデルでは捉えられていないシステムの脆弱性を反映している可能性があります.
- ALBIスコアを処置前評価に統合することで,TAVI患者に対するリスクの階層化を高めることができます.

Introduction to z Scores
11.3K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...

Lattice Centering and Coordination Number
12.2K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Center of Gravity

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...
