Insights

A vegan diet during pregnancy and exclusive breastfeeding can lead to severe vitamin deficiencies in infants, impacting development. Early detection and supplementation are crucial for both mother and child.

Area of Science:

  • Pediatrics
  • Nutrition Science
  • Maternal Health

Background:

  • Maternal vegan diets can restrict essential nutrient intake.
  • Exclusive breastfeeding is recommended but requires adequate maternal nutrition.

Observation:

  • A 10-month-old infant exclusively breastfed by a vegan mother presented with failure to thrive, megaloblastic anemia, and delayed psychomotor development.
  • The infant exhibited vitamin B12, vitamin K, and vitamin D deficiencies.
  • The mother showed similar vitamin deficiencies.

Findings:

  • Infant's condition included hematocytopenia and pervasive developmental disorders.
  • Vitamin supplementation led to normalization of biological markers.
  • The infant demonstrated significant weight gain and neurological improvement.

Implications:

  • Vegan diets during pregnancy and lactation necessitate careful monitoring for nutritional deficiencies.
  • Maternal and infant vitamin status must be assessed to prevent adverse health outcomes.
  • Proactive supplementation strategies are vital for infants born to mothers on restrictive diets.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Development of the Oral Microbiota01:28

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,...
Development of Human Microbiota01:30

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...
Parental Care00:55

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
Parentral Nutrition: Centeral and Peripheral Parental Nutrition01:27

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
