概括
修改的老年营养风险指数 (mGNRI) 准确地预测了全关节整形术 (TJA) 后的术后并发症. 患有低mGNRI得分的患者面临感染,伤口问题和重新手术的风险显著增加.
科学领域:
- 整形外科手术 整形外科手术
- 营养科学 营养科学
- 生物统计学 生物统计学
背景情况:
- 手术前营养不良是全关节整形术 (TJA) 后并发症的危险因素.
- 有限的研究比较营养指数来预测TJA结果.
- 这项研究评估了马斯特里赫特指数,奥诺德拉的PNI,GNRI和一个新的mGNRI.
研究的目的:
- 为了比较四个营养指数对TJA后术后并发症的预测效用.
- 为了确定TJA患者风险分层的最准确的营养指数.
- 评估营养状况与PJI,WCs,再接收和重新操作等结果之间的关联.
主要方法:
- 对1575名TJA患者 (2016-2021) 的回顾性队列研究.
- 收集了手术前的白蛋白,白蛋白前和淋巴细胞计数.
- 使用Youden指数,ROC曲线和多变量逻辑回归来分析结果和混因素 (BMI,年龄,CCI).
主要成果:
- 修改的老年营养风险指数 (mGNRI) 在预测不良结果方面表现出最高的准确性 (AUC=0.633).
- 低mGNRI (≤92.8) 患者的PJI,WCs,再入院和重新手术率显著更高.
- 低mGNRI独立预测增加了PJI (6.61x),WC (3.04x),再入院 (2.25x) 和重新手术 (2.75x) 的几率,在调整混因素后.
结论:
- mGNRI是一种简单,有效的工具,用于预测TJA后的术后并发症.
- 在预测准确度方面,mGNRI的表现优于其他营养指数 (马斯特里赫特,奥诺德拉的PNI,GNRI).
- 对于MGNRI低于92.8.8的TJA患者,应考虑营养优化.

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

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...
