概括
结肠直肠癌 (CRC) 缓解症会导致显著的骨肌肉损耗,影响身体功能. 这项研究揭示了CRC患有缓冲症的CRC患者的显微和宏观肌肉变化,将这些变化与减少的身体表现和生活质量联系起来.
科学领域:
- 在瘤学瘤学.
- 肌肉生理学 肌肉生理学
- 代谢功能障碍 代谢功能障碍
背景情况:
- 癌症缓解症是一种复杂的综合征,其特点是骨肌肉消耗和代谢功能障碍,在结肠直肠癌 (CRC) 患者中显著恶化结果.
- 在显微和宏观层面上了解骨肌肉的结构变化对于开发有效干预措施至关重要.
- 之前的研究突出了缓解症对身体表现的影响,但需要详细描述CRC肌肉变化的特征.
研究的目的:
- 检查与健康对照组 (HCs) 相比,结直肠癌 (CRC) 患者的微观和宏观骨肌肉纤维特征和肌肉体积,并与有或没有卡赫西亚患者进行比较.
- 探索这些肌肉变化与身体表现,生活质量和整体临床结果之间的关系.
- 为了确定特定的肌肉纤维类型变化和与CRC相关的缓解症相关的肌肉核含量变化.
主要方法:
- 纳入12名患有缓解症的CRC患者,25名没有缓解症的CRC患者和25名HC患者,其缓解症由体重减轻和缓解症分期得分来定义.
- 分析巨大的侧面肌肉和勃起脊柱肌肉活检,使用免疫组织化学分析纤维类型的横截面积 (CSA),分布,肌核含量和毛细血管密度.
- 通过三维超声波和计算机断层扫描分别评估肌肉体积和密度;使用短物理性能电池,手握强度和身体活动量表来评估身体功能;通过36项短形式调查测量生活质量.
主要成果:
- 与HCs和CRC患者没有白血病相比,患有CRC相关的白血病患者在横向巨中表现出II型肌肉纤维CSA减少.
- 与HC相比,没有缓解症的CRC患者显示肌肉纤维转移缓慢至快;在两种癌症组中,肌肉核含量都较低.
- 在患有CRC相关的长症的患者中观察到肌肉体积和密度的减少;肌肉特征,力量,身体表现和生活质量之间发现了积极的相关性.
结论:
- 结肠直肠癌患者,特别是患有白血病的患者,表现出II型肌肉纤维缩,肌核含量降低和身体功能受损.
- 显微 (纤维类型特异性缩,核细胞含量,毛细化) 和宏观 (肌肉体积,质量) 的骨肌肉变化在CRC缓冲症中明显.
- 这些结构性肌肉变化与减少身体功能和生活质量有显著的关联,这强调了有针对性的预康复和康复干预措施的必要性.

Skeletal Muscle Relaxants: Adverse Effects
773
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

Disorders of the Skeletal Muscle
1.7K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Assessment of the Rectum and Anus
1.1K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
