概括

医疗患者估计的每日总能耗 (TDEE) 往往不同于测量TDEE. 肌肉质量显著影响这些差异,这表明它在营养评估中的重要性.

科学领域:

临床营养学临床营养学
代谢研究研究代谢研究
患者评估患者评估

背景情况:

丹麦卫生局 (DHA) 建议为高危住院患者使用估计的每日总能耗 (TDEE) 模型.
对测量TDEE与此估计的准确性进行调查对于有效的患者护理至关重要.

研究的目的:

在医疗住院患者中,使用间接热量计 (IC) 将估计的TDEE (E) 与测量TDEE (M) 进行比较.
为了确定与E和M TDEE之间的差异相关的患者特征.

主要方法:

一项涉及148名医疗患者的横截面研究.
数据收集包括人体测量,间接热量计 (IC) 和医疗记录.
统计分析包括描述性统计,t测试和回归分析.

主要成果:

在总体患者群体中,在估计和测量TDEE之间观察到显著差异 (p < 0.001).
低估发生在BMI<25.0 kg/m2的患者中,而高估发生在BMI25.0-29.9 kg/m2的患者中.
肌肉质量与估计和测量TDEE之间的差异有很强的相关性 (p < 0.001).

结论:

DHA的TDEE估计模型显示出不准确性,特别是在BMI低或高的患者中.
肌肉质量是影响TDEE估计准确性的关键因素.
建议定期测量肌肉质量,特别是在风险患者中,尽管饮食摄入量充足,但体重减轻.

Energy Budgets

Energy Budgets

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Energy Balance

Energy Balance

The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Metabolic Rate

Metabolic Rate

The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

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.
