Insights

Premature infants, like those born small for gestational age (SGA), exhibit reduced insulin sensitivity. This early metabolic abnormality, linked to adverse perinatal environments, may persist into adulthood, increasing disease risk.

Area of Science:

  • Neonatal research
  • Metabolic health
  • Endocrinology

Background:

  • Low birth weight is linked to adult diseases like type 2 diabetes mellitus and insulin resistance.
  • Adverse perinatal environments may cause permanent reductions in insulin sensitivity, impacting adult health.
  • Insulin sensitivity reduction is documented in term, small for gestational age (SGA) individuals from childhood to adulthood.

Purpose of the Study:

  • To investigate metabolic abnormalities in premature infants.
  • To determine if premature infants exhibit similar metabolic issues as term SGA infants.
  • To assess if these abnormalities are independent of gestational age (SGA or AGA).

Main Methods:

  • Analysis of metabolic data from premature infants.
  • Comparison of metabolic profiles between premature and term SGA infants.
  • Evaluation of metabolic status irrespective of SGA or appropriate for gestational age (AGA) classification.

Main Results:

  • Premature infants demonstrate metabolic abnormalities.
  • These abnormalities are comparable to those seen in term SGA children.
  • Metabolic issues in premature infants occur regardless of SGA or AGA status.

Conclusions:

  • Premature birth into an adverse neonatal environment is associated with metabolic abnormalities.
  • These findings suggest early metabolic dysfunction in premature infants, similar to SGA infants.
  • Metabolic health in premature infants warrants further investigation for long-term implications.

Pathophysiology of Diabetes01:20

Pathophysiology 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...
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...

Diabetes 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...

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
Overview of Protein Metabolism01:21

Overview of Protein Metabolism

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...
