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.

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 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...

There are various healthcare agencies in the United States—some of which are managed by religious institutions and others by different government branches.
Parish nursing is a growing specialty nursing profession that focuses on holistic healthcare, health promotion, and illness prevention. It blends professional nursing practice with a health ministry, focusing on health and healing within the context of a Christian community.

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.

Machine learning identified key predictors of high plasma phosphorylated tau-181 (p-tau-181) in Hispanic/Latino adults. Diabetes, employment, and acculturation were significant factors, offering targets for Alzheimer's disease interventions.

Area of Science:

  • Neurology
  • Biomarkers
  • Machine Learning

Background:

  • Plasma phosphorylated tau-181 (p-tau-181) is a reliable blood-based biomarker for Alzheimer's disease (AD), reflecting tau pathology.
  • Elevated p-tau-181 correlates with amyloid deposition, AD progression, and cognitive decline, supporting its use in diagnosis and monitoring.
  • Understanding p-tau-181 predictors is crucial for clinical utility, disease mechanism insights, and targeted interventions, especially in US Hispanic/Latino adults disproportionately affected by AD.

Purpose of the Study:

  • To identify predictors of high p-tau-181 levels in a deeply characterized population of middle-aged and older US-based Hispanic/Latino adults.
  • To leverage machine learning models to analyze life-course risk factors for AD neuropathologic change.
  • To inform targeted intervention strategies for modifying AD-related pathologic processes in this demographic.

Main Methods:

  • Utilized data from the Hispanic Community Health Study/Study of Latinos and its ancillary Study of Latinos-Investigation of Neurocognitive Aging (N=5,175).
  • Employed Random Forest machine learning models to predict high p-tau-181 levels (binary measure: >90th vs. ≤90th percentile).
  • Assessed 33 potential baseline predictors, including life-course risk factors, using permutation techniques for factor importance.

Main Results:

  • The machine learning model demonstrated moderate discriminative performance (AUC=0.73) in predicting high p-tau-181 levels.
  • Top predictors identified included diabetes, employment status, and the language subscale of the Short Acculturation Scale for Hispanics.
  • These findings highlight the influence of cardiometabolic and social determinants on p-tau-181 levels.

Conclusions:

  • Multiple life-course factors predict p-tau-181 levels in middle-aged and older Hispanic/Latino adults.
  • Cardiometabolic risk (e.g., diabetes) and social determinants (e.g., employment, acculturation) are key areas for intervention.
  • Further research will validate these models and expand findings to other Alzheimer's disease biomarkers.
