概括

免疫检查点抑制剂 (ICI) 三合一综合征,一种严重的ICI肌炎形式,在六个月内显著增加死亡率. 隔离ICI肌肉炎的生存率与不发展肌肉炎的患者相似.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
神经学神经学

背景情况:

免疫检查点抑制剂 (ICI) 是关键的癌症疗法.
ICI诱导的肌肉炎是一种罕见但严重的不良事件.
特别严重的是ICI肌肉炎三合体综合征 (肌肉炎,心肌炎,肌痛性肌痛症).

研究的目的:

为了描述ICI肌肉炎的临床特征.
为了确定ICI肌肉炎患者的全因死亡率.
为了比较ICI三位症综合征和孤立的ICI肌炎之间的结果.

主要方法:

美国退伍军人接受ICI治疗的国家回顾性队列研究 (2011年6月-2022年2月).
在临床笔记中,因肌激酶 (CK) 和/或"肌炎"升高而确定的病例.
图表审查将患者分类为ICI三合体综合征或孤立的ICI肌炎.

主要成果:

在29296名接受ICI治疗的退伍军人中,有68人 (0.2%) 患有ICI肌炎 (23人组,45人隔离).
对于ICI三综合征,平均存活时间为2.5个月,而对于单独的肌肉炎,平均存活时间为20.4个月.
三合一综合征的六个月死亡率为60.0%,与孤立肌肉炎的30.2%相比.

结论:

ICI三元综合征与ICI治疗后的前六个月中较高的死亡率和较短的存活率有关.
隔离ICI肌肉炎的死亡率与没有肌肉炎的ICI治疗患者相似.
早期识别和治疗ICI肌炎至关重要.

The Spindle Assembly Checkpoint

The Spindle Assembly Checkpoint

The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

Dark Triad and Person Perception

Dark Triad and Person Perception

Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et...

¹H NMR: Interpreting Distorted and Overlapping Signals

¹H NMR: Interpreting Distorted and Overlapping Signals

Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

Eukaryotic Transcription Inhibitors

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...
