概括
代谢功能障碍,而不仅仅是体重过重,预测认知能力下降的速度更快. 早期管理代谢问题是痴呆症预防策略的关键.
科学领域:
- 代谢健康和认知功能
- 慢性疾病的流行病学.
背景情况:
- 代谢性肥胖现象型越来越被认为是严重的健康问题.
- 了解新陈代谢健康,体重和认知衰退之间的联系对公共健康至关重要.
- C-反应蛋白 (CRP) 是一种炎症标志物,可能在这种关联中发挥作用.
研究的目的:
- 调查不同代谢肥胖现象和认知衰退之间的关联.
- 评估C反应蛋白 (CRP) 在这种关系中的潜在调解作用.
主要方法:
- 一项纵向队列研究 (ELSA-巴西) 与12,795名参与者进行了平均8年的随访.
- 根据体重指数 (BMI) 和代谢健康标准 (包括腰比,糖尿病和高血压) 定义了六种代谢表型.
- 通过记忆,口语流和Trail-Making测试来评估全球认知;调解分析探索了CRP的作用.
主要成果:
- 无论BMI如何,新陈代谢不健康的表型显著与更快的认知衰退有关.
- 代谢健康的超重和肥胖与认知能力下降无关.
- 腰部至部比率 (WHR) 与认知能力下降有关,而整体BMI则没有;没有发现CRP中介的证据.
结论:
- 代谢功能障碍是认知能力下降的更强的预测因素,而不是仅仅是体重过重.
- 早期识别和管理所有体重类别的代谢功能障碍是预防痴呆症的建议.

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion
169
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...

Magnetic Declination
413
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...

Genome-wide Association Studies-GWAS
15.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

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...

Cognitive Dissonance
36.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
