Summary
Pregnant women adhering to a Mediterranean diet (MD) exhibit distinct metabolic profiles, with lower inflammatory markers. This dietary pattern is linked to specific gut microbial metabolites, offering insights into perinatal health.
Area of Science:
- Nutritional Science
- Metabolomics
- Maternal Health
Background:
- The Mediterranean diet (MD) is associated with positive maternal and offspring health outcomes.
- Inflammatory pathways are potential mediators of the MD's health benefits.
- Understanding the metabolic impact of dietary adherence during pregnancy is crucial for perinatal health.
Purpose of the Study:
- To compare metabolic profiles of pregnant women with high versus low adherence to the MD.
- To investigate the relationship between MD adherence, metabolic phenotypes, and inflammatory markers.
- To identify potential biomarkers for assessing health risks during pregnancy.
Main Methods:
- Utilized the ORIGINS cohort, stratifying 51 pregnant women based on MD adherence.
- Employed 1H Nuclear Magnetic Resonance (NMR) spectroscopy for serum and urine metabolic profiling at 36 weeks gestation.
- Analyzed the correlation between dietary patterns, metabolite profiles, and inflammatory status.
Main Results:
- Significant differences observed in food choices and metabolic profiles between high (HMDA) and low (LMDA) MD adherence groups.
- HMDA group showed higher urinary hippurate and lower creatine, associated with reduced meat and increased vegetable intake.
- HMDA group exhibited lower serum inflammatory biomarkers (GlycA, GlycB) and associations with plant-based nutrients; LMDA group showed associations with branched-chain amino acids and creatine.
Conclusions:
- High MD adherence during pregnancy is associated with a distinct metabolic phenotype, aligning with reported food intake.
- Metabolic differences highlight significant variations in systemic inflammation and gut-microbial metabolites.
- Findings provide novel insights into the mechanisms of perinatal health and identify potential biomarkers for risk assessment.

01:20Pathophysiology of Diabetes
949
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,...

2.4K
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...

01:07Teratogenicity
2.5K
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...

01:20Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

01:19Overview of Carbohydrate Metabolism
1.1K
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

02:27Background and Environment Affect Phenotype
6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
