Insights

A new developmental model suggests chronic diseases originate from variations in fetal development. Nutrient supply changes during pregnancy permanently alter gene expression, impacting key systems linked to disease.

Area of Science:

  • Developmental biology
  • Chronic disease etiology
  • Epigenetics

Background:

  • Chronic diseases pose a significant global health burden.
  • Current models often focus on postnatal factors.
  • The developmental origins of health and disease (DOHaD) hypothesis suggests early life influences health outcomes.

Purpose of the Study:

  • To introduce and elaborate on a novel

Main Methods:

  • Conceptual model development.
  • Literature synthesis on fetoplacental development and gene expression.
  • Identification of key biological systems affected by developmental programming.

Main Results:

  • Proposes that variations in fetoplacental development alter nutrient supply to the fetus.
  • These alterations permanently modify gene expression through "programming."
  • Programmed changes affect critical systems: immune, antioxidant, inflammatory, and stem cell functions, predisposing to chronic disease.

Conclusions:

  • This developmental model offers a new framework for understanding chronic disease origins.
  • Focuses on normal variations in fetal development as a root cause.
  • Highlights the long-term impact of early-life "programming" on disease susceptibility.

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Concepts of Health and Illness01:29

Concepts of Health and Illness

Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
Lifestyle Factors and Health01:20

Lifestyle Factors and Health

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.

Theoretical Foundations of Nursing Practice

Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
