Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

科学领域:

  • 神经学和老年学的神经学和老年学.
  • 生物标志物发现发现
  • 流行病学 流行病学

背景情况:

  • 临床前阿尔茨海默氏症 (AD) 的特点是,在认知不受损的个体中,有AD病理学的生物标志物证据.
  • 目前的诊断方法 (PET扫描,脑脊液采集) 是侵入性的,对于没有认知障碍的人群来说不是标准的.
  • 基于血液的生物标志物 (BBM) 为AD检测提供了一种最小侵入性,可扩展性和成本有效的替代方案.

研究的目的:

  • 估计美国,日本,德国和中国50岁以上临床前AD患有认知衰退最大风险的个体数量.
  • 评估血p-tau217水平在识别高风险的临床前阿尔茨海默病患者群体中的潜在有用性.
  • 为未来的AD干预提供医疗保健基础设施和预算规划的信息.

主要方法:

  • 利用国家特定的人口普查数据和基于文献的痴呆症,MCI和粉样蛋白PET阳性的流行率估计.
  • 应用了最近的发现,将顶端三角质血p-tau217水平与粉样蛋白阳性,认知不受损的个体中临床进展的最高速率联系起来.
  • 通过考虑三分之一的粉样蛋白-PET阳性临床前AD人群来估计高风险的临床前AD人群.

主要成果:

  • 根据粉样蛋白PET阳性估计的临床前AD人群 (50+):美国 (22.0M,18.3%),日本 (11.2M,19.0%),德国 (7.0M,18.5%) 和中国 (90.7M,17.0%).
  • 估计高风险的临床前阿尔茨海默病人群 (顶端三位数p-tau217):美国 (73万,6.1%),日本 (37万,6.3%),德国 (23万,6.2%) 和中国 (3020万,5.7%).

结论:

  • 显著的临床前阿尔茨海默病患者数量凸显了有效查方法的必要性.
  • 像血p-tau217这样的基于血液的生物标志物可以帮助识别高风险个体,可能减少医疗保健负担.
  • 对临床前阿尔茨海默病的血p-tau217患病率的进一步研究对于经济影响评估和治疗规划至关重要.
