概括
在肥胖儿童中,季节性和年龄因素,而不是脂肪,显著影响维生素D水平. DXA和BIA方法在生理学建模中显示了类似的结果,表明DXA在这个队列中没有比BIA有显著的优势.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 营养科学 营养科学
- 身体组成分析 身体成分分析
背景情况:
- 生物阻抗评估 (BIA) 与双能X射线吸收计 (DXA) 相比,通常低估脂肪度.
- DXA和BIA在生理学建模中的比较实用性,特别是关于肥胖儿童维生素D状况的比较实用性,仍然不清楚.
- 了解这些关系对于管理维生素D缺乏和儿童肥胖症相关代谢并发症至关重要.
研究的目的:
- 为了在肥胖儿童中比较DXA和BIA,模拟肥胖和25(OH) D水平之间的关联.
- 调查脂肪在维生素D和代谢结果之间的关系中的调解作用.
- 用两种脂肪度测量方法评估维生素D-PTH-轴.
主要方法:
- 对165名简单肥胖儿童的横截面分析,不包括那些接受维生素D预防的儿童.
- 通过DXA和BIA测量肥胖度;血清25(OH) D,PTH,,酸盐,葡萄糖,胰岛素,HOMA-IR和脂质进行分析.
- 统计分析包括部分相关性,线性回归,调解模型和布兰德-阿尔特曼分析,根据年龄,性别和季节进行调整.
主要成果:
- DXA显示身体脂肪百分比 (46.6%) 比BIA (36.7%) 高.
- 维生素D水平与脂肪率无异常反向相关,但根据年龄和季节调整后,脂肪率不是一个显著的决定因素.
- 没有通过脂肪性发现维生素D与代谢关联的调解;维生素D-PTH-轴在各种模式中保持一致.
结论:
- 在儿童肥胖症中,季节性和年龄相关因素是25~OH) D变化的主要驱动因素,在这个群体中,肥胖症的贡献很小.
- 维生素D在这个群体中表现出内分泌关联,但没有显著的代谢关联.
- 对于这个同质的儿科肥胖群体的生理建模,DXA对BIA没有明显的优势.

Drug Dosing: Obese Patients
325
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

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...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
287
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

Obesity
1.5K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
