概括
极度肥胖不会显著改变下丘脑-垂体-上腺轴的功能,正如德甲抑制试验 (DST) 所指出的那样. 临床解释肥胖中皮质醇升高的情况应该考虑代谢因素,而不仅仅是体重指数 (BMI).
科学领域:
- 内分泌学 在内分泌学.
- 代谢健康 代谢健康
- 肥胖医学 肥胖医学
背景情况:
- 1mg德克萨米他抑制试验 (DST) 在肥胖方面具有可变的结果.
- 极度肥胖 (BMI ≥50 kg/m2) 对下丘脑-垂体-上腺轴功能的影响尚不清楚.
研究的目的:
- 为了评估不同BMI类别的德克萨米他后皮质醇水平.
- 评估BMI,皮质醇水平和代谢参数之间的关联.
主要方法:
- 对352名肥胖成人 (BMI≥30 kg/m2) 的回顾性分析.
- 分为BMI组的分层:30.0-39.9,40.0-49.9和≥50.0公斤/米2.
- 临床,人体测量和实验室数据的比较,包括1mg夜间DST结果.
主要成果:
- 德克萨米他后的皮质醇水平在BMI类别之间显示了适度的差异 (p=0.038).
- 不充分的皮质醇抑制是罕见的 (1.1%) 并不始终与更高的BMI相关.
- 超肥胖 (BMI ≥50 kg/m2) 与更高的高血压和糖尿病率有关.
结论:
- 肥胖症中德克萨米他后皮质醇升高可能不仅仅是由于体重.
- 需要对真正的高皮质醇症进行评估,并根据代谢表型指导解释.
- 仅仅BMI不应该决定肥胖患者的DST结果的临床解释.

Drug Dosing: Obese Patients
263
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
282
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...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Reduced Mass Coordinates: Isolated Two-body Problem
2.4K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Obesity
1.3K
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...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
