- 肥胖问题研究研究
- 生物医学工程 生物医学工程
背景情况:
- 全球肥胖率的上升使创伤护理复杂化,引发了"肥胖悖论".
- 这种现象需要对其潜在机制进行调查,特别是在严重受伤的患者中.
研究的目的:
- 评估严重受伤的肥胖患者的生物机械保护假设.
- 评估肥胖对初始损伤严重程度和临床结果的影响.
主要方法:
- 对1549名成年创伤患者的回顾性分析 (伤害严重性评分 (ISS) ≥9).
- 患者被分为非肥胖 (BMI <30) 和肥胖 (BMI ≥30) 队列.
- 与ISS的比较,缩短伤害量表 (AIS) 的得分,死亡率,SAPS II和停留时间 (LOS).
主要成果:
- 肥胖患者的整体ISS和区域AIS分数 (头部/部,腹部/骨盆) 较低,支持生物机械保护.
- 肥胖患者患病率较高 (SAPS II,总LOS,ICU LOS),但在医院死亡率相似.

Hypodermis
7.2K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

Obesity
1.1K
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...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
225
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: Obese Patients
202
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 Metabolism and Excretion
161
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...

Physiological Barriers
5.0K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...
