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 System01:26

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...

Area of Science:

  • Neuroscience
  • Gerontology
  • Public Health

Background:

  • Alzheimer's disease (AD) is a common neurodegenerative disorder in the elderly.
  • Etiology of AD is not fully understood, necessitating early detection and intervention.
  • Mild Cognitive Impairment (MCI) is a prodromal stage for AD, making it a key focus for research.

Purpose of the Study:

  • To investigate the role of lifestyle and behavioral factors in the progression from MCI to AD.
  • To identify novel predictors of AD transition using advanced statistical methods.
  • To understand how factors like sleep and daily activities influence AD development.

Main Methods:

  • Utilized data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort.
  • Analyzed 848 individuals with MCI, including 336 who converted to AD.
  • Employed survival analysis techniques: Cox proportional hazards models, time-dependent covariates Cox models, and Aalen's additive regression models.

Main Results:

  • Daily functional activity scores and sleep disorders significantly predicted MCI to AD progression.
  • Socio-demographic and lifestyle variables were associated with increased AD risk over time.
  • Survival models identified time-dependent and non-linear effects of predictors.

Conclusions:

  • Behavioral and lifestyle factors are critical in predicting MCI to AD transition.
  • Sleep disorders and daily functional activities are key predictors.
  • Advanced survival analyses offer insights into AD progression dynamics.
