概括
营养不良会影响外科手术的结果,这项研究发现男性和女性的身体成分标志物不同. 识别这些特定于性别的成像特征可以帮助预测腹部手术患者的营养不良风险.
科学领域:
- 放射学和成像学 放射学和成像学
- 手术瘤学手术瘤学
- 营养科学 营养科学
背景情况:
- 营养不良是不良外科手术结果的重要预测因素,但在手术前很难确定.
- 现有的研究缺乏详细的调查,以性别为特征的身体组成和营养不良之间的关联.
- 腹部手术患者面临风险,需要更好的术前营养评估工具.
研究的目的:
- 评估前手术成像衍生的身体组成特征和临床营养不良之间的性别特定关联.
- 确定与腹部手术的男性和女性营养不良相关的明显的肌肉和脂肪组成模式.
主要方法:
- 对1143名接受选择性腹部手术的患者进行了截面研究,这些患者接受了手术前的CT扫描.
- 一个深度学习算法从CT扫描中量化了肌肉群和脂肪储存.
- 经注册营养学家诊断的临床营养不良;性别特异的后勤回归分析了相关性.
主要成果:
- 20.2%的患者患有临床营养不良,患病率因程序而异.
- 营养不良与男性和女性肌肉体积的减少有关;肌肉骨病,特别是女性肌肉骨.
- 发现了明显的关联:男性 (psoas, quadratus lumborum体积,直立脊柱减弱),女性 (psoas体积/减弱) 和两性 (增加皮下/内脏脂肪减弱).
结论:
- 男性和女性表现出与临床营养不良相关的独特身体组成特征.
- 对肌肉和脂肪特征的全面分析揭示了这些性别特异性关系.
- 这些发现为开发预测工具提供了基础,以便更早地识别与营养有关的外科风险.

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
343
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
