Maternal nutrition in twin pregnancy
Acta Geneticae Medicae Et Gemellologiae
|January 1, 1982
Summary
Maternal nutrient intake, including energy, protein, zinc, copper, and iron, shows no significant difference between twin and singleton pregnancies. This finding is unexpected given the increased demands of carrying twins.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Nutritional Science
Background:
- Twin pregnancies present unique physiological demands on maternal nutrition.
- Understanding maternal adaptations in twin gestations is crucial for optimizing outcomes.
Purpose of the Study:
- To compare energy and protein intake between twin and singleton pregnancies.
- To investigate maternal plasma levels of key micronutrients (zinc, copper, iron) in twin versus singleton gestations.
Main Methods:
- Utilized 24-hour urinary nitrogen excretion to assess protein and energy intake.
- Measured plasma concentrations of zinc, copper, and iron in pregnant individuals.
Main Results:
- Urinary nitrogen values, indicative of nutrient intake, were similar in women with twin and singleton pregnancies.
- Plasma levels of dietary zinc, copper, and iron did not differ between the two groups.
- The relationship between urinary nitrogen and nitrogen intake was consistent across both pregnancy types.
Conclusions:
- Maternal nutritional status, in terms of energy, protein, and key micronutrients, appears to adapt similarly in twin and singleton pregnancies despite increased fetal demands.
- Further research is needed to elucidate the specific adaptive mechanisms in twin pregnancies.

00:55Parental 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.
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:15Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

01:20Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

01:28Development 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,...
