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...

Summary
This summary is machine-generated.

Neuroimaging markers for dementia, including amyloid and tau deposition, differ by race/ethnicity and gender. Reducing cardiovascular risk may help mitigate these disparities, particularly for women of color.

Area of Science:

  • Neuroimaging
  • Dementia Research
  • Health Disparities

Background:

  • Emerging data shows race/ethnicity and gender influence dementia pathology and cardiovascular risk.
  • This study investigates how these factors impact neuroimaging markers of dementia.

Purpose of the Study:

  • To examine racial/ethnic and gender differences in neuroimaging markers of cerebrovascular disease and neurodegeneration.
  • To determine if cardiovascular risk partially mediates these associations.

Main Methods:

  • Utilized Health and Brain Study-Health Disparities (HABS-HD) data from dementia-free participants.
  • Employed linear and multinomial regression, adjusting for demographic and socioeconomic factors.
  • Incorporated Framingham Risk Score (FRS) to assess mediation by cardiovascular risk.

Main Results:

  • Women of color exhibited higher odds of intermediate/high cardiovascular risk.
  • Black participants showed lower amyloid-beta SUVR, while women of color had greater medial temporal tau SUVR.
  • Black participants had greater white matter hyperintensity volume (WMHV), with partial mediation by FRS in Black women.

Conclusions:

  • Cardiovascular risk and dementia neuroimaging markers are interconnected with race/ethnicity.
  • Women of color may benefit from cardiovascular risk reduction to lessen small vessel disease burden.
