概括
布罗利祖马布与化疗一起改善了三阴性乳腺癌 (TNBC) 的结果. 然而,一种罕见的与免疫相关的不良事件,即获得的脂质变,可能会发生,需要长期监测患者.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 皮肤病学 皮肤病学
背景情况:
- 三阴性乳腺癌 (TNBC) 是一种具有高复发风险的侵袭性亚型.
- 与 pembrolizumab 结合的新辅助化疗已经显示出改善了TNBC的病理完整反应 (pCR) 和生存率.
- 长期免疫相关不良事件 (irAEs) 是免疫疗法的一个问题,即使在治疗环境中.
研究的目的:
- 在TNBC患者的辅助 pembrolizumab 后,报告一种获得性脂质营养不良的病例,一种未被认可的 irAE.
- 突出长期IRAE监测在接受免疫治疗的患者的重要性.
- 提出关于患者实现pCR的潜在免疫疗法降级策略的问题.
主要方法:
- 一名结节阳性TNBC患者的病例报告,该患者接受了新辅助化学免疫疗法和辅助 pembrolizumab 治疗.
- 临床和组织学评估所获得的脂质变.
- 评估治疗反应和不良事件.
主要成果:
- 患者在新辅助疗法后实现了pCR.
- 在辅助 pembrolizumab 治疗后,该患者发展了获得的脂质,其特征是皮下脂肪损失,脂质不良和肝脏脂肪症.
- 组织学证实了脂肪细胞亡与淋巴细胞透.

01:51Mechanisms of Retrovirus-induced Cancers
7.0K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

01:06Scalar and Vector Triple Products
4.5K
Two vectors can be multiplied using a scalar product or a vector product. The resultant of a scalar product is scalar, while with vector products, the resultant is a vector. These rules of the scalar or vector product between two vectors can be applied to multiple vectors to obtain meaningful combinations. The scalar triple product is the dot product of a vector with the cross product of two vectors.

38.5K
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

00:58Positive, Negative, and Zero Work
22.2K
Work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on a body that undergoes a displacement from one position to another. By definition, the work done by a force is the integral of the force with respect to the displacement along its path. Forces can vary as a function of position, and displacements can occur along various paths between two points. The magnitude of a force multiplied by the cosine of the angle that the force makes...

01:30Negative and Cognitive Symptoms of Schizophrenia
557
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
