概括
在维护血液透析患者中,肥胖与较高的死亡率有关,挑战了肥胖悖论. 与正常体重相比,超重状态并没有显著改变生存率,这表明需要谨慎地解释BMI.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 流行病学 流行病学
- 老年学是指老年学的学科.
背景情况:
- 维护血液透析 (MHD) 患者的肥胖悖论,其中更高的BMI与更好的生存率有关,仍然存在争议.
- 关于东欧血液透析患者,特别是老年人的体重状况和死亡率的数据有限.
研究的目的:
- 描述罗马尼亚MHD队列中的体重分布和心脏代谢并发症.
- 评估BMI类别与该人群中全因死亡率之间的关联.
主要方法:
- 在罗马尼亚八个中心对679名MHD患者进行了回顾性队列研究.
- 分析包括人口统计,临床,实验室和心声回声数据.
- 卡普兰-梅尔曲线和考克斯比例危险模型评估了生存和死亡预测指标.
主要成果:
- 在多变量分析中,肥胖 (BMI ≥30 kg/m2) 独立地与增加全因死亡率 (HR 1.411,p=0.045) 相关.
- 随着BMI (正常体重:7.56年;超重:4.56年;肥胖:3.92年) 的增加,中位生存时间显著降低.
- 超重状态没有显示出比正常体重的生存优势.
结论:
- 根据BMI,肥胖与罗马尼亚MHD患者的死亡率增加有关,这与传统的肥胖悖论相矛盾.
- 这些发现表明,需要对BMI在MHD患者结果中的作用进行更细致的解释.
- 进一步的研究是有必要的,以探索脂肪和透析人群的存活之间的复杂关系.

Drug Dosing: Obese Patients
216
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
233
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...

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 Metabolism and Excretion
164
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...

Chronic Kidney Disease II: Clinical Manifestations
540
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Hemodialysis II: Procedure and Complications
610
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
