- 内分泌学 在内分泌学.
- 遗传学 是一个遗传学.
背景情况:
- 冠心病 (CHD) 是主要心血管事件的主要原因,包括急性心肌梗塞.
- 目前关于血清25-基维生素D (25(OH) D) 与心血管疾病之间的联系的研究主要是观察性的,这可能会产生偏见的风险.
- 调查25~OH) D水平与CHD之间的因果关系对于了解心血管健康至关重要.
研究的目的:
- 调查血清25-基维生素D (25(OH) D水平与冠状动脉心脏病 (CHD) 风险之间的潜在因果相互作用.
- 利用门德尔的随机化来克服观察性研究在评估25(OH) D-CHD关系方面的局限性.
主要方法:
- 采用了一种双样,双向的门德尔随机化设计.
- 利用来自芬兰基因数据库的大规模遗传数据,用于心血管疾病病例 (n=21,012) 和对照病例 (n=197,780).
- 采用来自GWAS目录的欧洲人口血清25(OH) D水平的数据 (n=417,580).
主要成果:
- 逆方差加权 (IVW) 分析表明,血清25(OH) D和心脏病风险 (P <0.05) 之间存在统计学上显著的逆关系.
- 血清25(OH) D度的增加与患心脏病的风险降低有关.
- 相反,较高的心脏病风险与较低的血清25(OH) D度有关 (P = 0.04).
结论:
- 血清25-基维生素D度升高似乎是预防冠心病的保护因素.
- 这些发现表明一种潜在的双向关系,其中心血管疾病也可能影响人体血清25...OH) D水平.

Role of Skin in Vitamin D Synthesis
4.9K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Causality in Epidemiology
182
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Genome-wide Association Studies-GWAS
12.2K
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...

Psychoneuroimmunology: Cardiovascular Disease
20
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Hazard Ratio
72
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
