まとめ
CAR-HEMATOTOX (HTX) や改変されたEASIX (m-EASIX) のような臨床リスクスコアは,再発性/耐性多発性骨髄腫の双特定T細胞エンゲージャー (TCE) を投与している患者の合併症や不良結果を予測することができます.
科学分野:
- 血液学 ヘマトロジ
- 腫瘍学 腫瘍学
- 免疫療法による免疫療法です.
背景:
- ビスペシフィックT細胞エンゲージャー (TCEs) は,再発性/耐性多発性骨髄腫 (RRMM) に対して臨床上の利点を提供しています.
- 重篤な毒性および治療失敗は,TCEの有効性を制限する可能性があります.
- 既存のリスクスコア (CAR-HEMATOTOX,EASIX,m-EASIX) は,CAR T細胞治療には有効ですが,TCE治療には有効ではありません.
研究 の 目的:
- CAR-HEMATOTOX (HTX) と改変されたEASIX (m-EASIX) のスコアが,TCEで治療されたRRMM患者のアウトカムと毒性を予測する有用性を評価する.
- これらのリスクスコアとステップアップ投与中の合併症の関連性,および全般的な治療応答を評価する.
主な方法:
- TCEで治療されたRRMM患者の独立した発見 (n=123) と検証 (n=155) コーホートの分析.
- ベースラインのHTX ≥3またはm-EASIX > 平均スコアと臨床結果との関連性の評価.
- 長期の入院,抗生物質の使用,発熱,細胞減量,重度の感染症,および応答率との相関の評価.
主要な成果:
- HTX ≥3またはm-EASIX > 中位値を有する患者は,ステップアップ投与中に長期入院,抗生物質治療,発熱のリスクが著しく高かった.
- これらのリスクスコアは,介入を必要とするサイトペニアの増加と重症感染症の密度の上昇と関連していました.
- 高いスコアは,より低い客観的な応答率,進行のない生存率,全生存率と相関しています.
結論:
- CAR-HEMATOTOX (HTX) と改変されたEASIX (m-EASIX) のスコアは,RRMMにおけるTCE治療の前にリスクの階層化の可能性を示しています.
- これらのスコアは,毒性および非最適の結果のリスクが高い患者を特定し,積極的な管理を可能にするのに役立ちます.
- これらのスコアをTCE治療戦略の最適化のための臨床実務に統合するために,さらなる検証が必要である.

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

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...

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
