Development of Immunocompetence01:22

Development of Immunocompetence

778
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Transcytosis of IgG01:15

Transcytosis of IgG

4.0K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Imprinting01:22

Imprinting

10.9K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Feedback Loops01:01

Feedback Loops

63.6K
In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.1K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Immunological Memory01:23

Immunological Memory

15.0K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Summary

Antenatal colostrum expression is safe but offers no proven breastfeeding benefits for low-risk pregnancies. It may help high-risk infants, but routine use is not recommended without more evidence.

Area of Science:

  • Maternal-Fetal Medicine
  • Neonatal Care
  • Lactation Science

Background:

  • Antenatal colostrum expression involves hand-expressing and storing breast milk during late pregnancy.
  • Initially for high-risk newborns (e.g., infants of diabetic mothers), it's now promoted for low-risk pregnancies.
  • Widespread adoption lacks robust population-level evidence.

Purpose of the Study:

  • To evaluate the evidence supporting antenatal colostrum expression.
  • To assess its safety and efficacy in various pregnancy contexts.
  • To inform clinical recommendations regarding its routine use.

Main Methods:

  • Review of randomized controlled trials and clinical evidence.
  • Analysis of maternal and infant outcomes.
  • Assessment of practice implications beyond clinical results.

Main Results:

  • Antenatal colostrum expression is safe for pregnant women with diabetes, with no increased preterm birth risk.
  • No significant improvements in breastfeeding initiation, exclusivity, or duration were observed compared to standard care.
  • Concerns include maternal mastitis, anxiety, and potential infant overfeeding or latch issues.

Conclusions:

  • Antenatal colostrum expression can benefit specific high-risk pregnancies, especially for anticipated neonatal hypoglycemia.
  • Current evidence does not support universal recommendation for all pregnant women.
  • Clinician judgment and individualized counseling should guide its use; it's a supportive tool, not standard prenatal care.
