概括
在加拿大,超过一半的慢性乙型肝炎 (CHB) 感染仍然未被诊断,阻碍了消除的努力. 这项研究开发了一个新的框架来估计全国范围内的CHB患病率和未诊断病例.
科学领域:
- 流行病学 流行病学
- 公共卫生 公共卫生
- 数学建模的数学建模
背景情况:
- 慢性乙型肝炎 (CHB) 在加拿大是一个重大的健康挑战,影响着相当一部分人口.
- 无声的,往往无症状的CHB性质使公共卫生干预和到2030年消除的目标变得复杂.
研究的目的:
- 开发和应用一个新的框架来估计加拿大的全国性CHB流行率.
- 量化CHB感染人口中未被诊断的比例.
主要方法:
- 开发了一个数学状态转换模型,反映了CHB的自然历史.
- 该模型使用加拿大公共卫生局和加拿大统计局 (2007-2021) 的国家数据进行校准.
主要成果:
- 2021年加拿大的CHB全国估计患病率为0.483% (95% CI 0.443%-0.535%).
- 估计约有54.3% (95% CI 50.9%-58.9%) 的CHB患者没有被诊断出来.
结论:
- 开发的框架提供了可靠的CHB患病率估计,与之前的血清患病率研究一致.
- 未来的研究可以利用详细的卫生行政数据进行更详细的,省或年龄特定的CHB患病率估计.

01:07Physiological Pharmacokinetic Models: Incorporating Hepatic Transporter-Mediated Clearance
79
Drug transporters are critical in drug absorption, distribution, and excretion processes. They should be included in physiological-based pharmacokinetic (PBPK) models, which help predict human drug disposition. However, predicting this is challenging during drug development, especially when liver transport is involved. However, with a realistic representation of body transport processes, an accurate model may be possible.

01:08Prevalence and Incidence
802
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
