概括
标准的营养评估显示,在血液性恶性瘤中,预后价值有限. 一个新的工具,血液学标志物-患者生成主观全球评估 (HMPG-SGA),整合生物标志物,显示这些患者的生存预测得到了改善.
科学领域:
- 在瘤学瘤学.
- 营养科学 营养科学
- 生物统计学 生物统计学
背景情况:
- 血液性恶性瘤与代谢失调和营养不良,恶化的结果和生存有关.
- 现有的营养评估工具在血液癌症患者中缺乏验证,造成了证据差距.
- 本研究评估了当前营养工具在这个人群中的预后性能.
研究的目的:
- 系统地评估8种营养评估仪器在患有血液性恶性瘤的患者的预后性能.
- 探索一种新的综合评估框架,反映出这种患者群体特有的代谢特征.
主要方法:
- 来自INSCOC注册表的1067名血液恶性瘤患者的前性队列研究.
- 分析了八个营养评估系统:PG-SGA,mPG-SGA,PG-SGA SF,abPG-SGA,NRS-2002,GLIM,得分-GLIM,以及KPS.
- 使用Kaplan-Meier,Cox回归,线性回归,LASSO回归,AUC和C指数分析来评估预后价值并确定生物标志物.
主要成果:
- 所有八种营养评估工具都显示出与生存的统计学上显著关联,但预后歧视有限 (AUC从0.473到0.561不等).
- 一种新的复合工具,血液学标志物-患者生成主观全球评估 (HMPG-SGA),结合了白蛋白-球蛋白比率 (AGR),证明了改善的预后值 (AUC 0.616,C指数 0.605).
- HMPG-SGA与整体存活率有显著的相关性 (p < 0.001).
结论:
- 传统的营养评估工具对血液性恶性瘤患者的整体生存预后能力有限.
- 该HMPG-SGA,整合营养评估与血液学指标,如AGR,显示初步承诺作为预后工具.
- 进一步验证HMPG-SGA的临床应用在治疗血液恶性瘤时是有必要的.

Bone Marrow Sampling and Transplants
2.2K
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
998
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
