Insights

Screening guidelines for infants small for gestational age (SGA) vary significantly worldwide. This review highlights inconsistencies in SGA hypoglycaemia screening criteria and timing, indicating a need for standardized recommendations.

Area of Science:

  • Neonatal Medicine
  • Pediatric Endocrinology

Background:

  • Hypoglycaemia poses a significant risk to infants born small for gestational age (SGA).
  • Current global screening guidelines for SGA infants exhibit considerable variation.

Purpose of the Study:

  • To review and analyze published hypoglycaemia screening guidelines for SGA infants.
  • To evaluate the characteristic features of hypoglycaemia in SGA infants to assess the relevance of current screening practices.

Main Methods:

  • A narrative review of studies from PubMed and Cochrane Database of Systematic Reviews.
  • Inclusion of government and national healthcare institution guidelines for hypoglycaemia screening in term and near-term SGA infants.

Main Results:

  • Significant discrepancies exist among international guidelines regarding which SGA infants require screening (e.g., <10th percentile vs. <2nd percentile).
  • Variations observed in hypoglycaemia cut-off values and the duration of glucose monitoring (4-24 hours).
  • Reported incidence of hypoglycaemia in SGA infants ranges from 12% to 52%, typically occurring 2-6 hours after birth.

Conclusions:

  • Existing hypoglycaemia screening guidelines for SGA infants lack uniformity.
  • Further research is essential to develop robust and consistent international guidance for managing hypoglycaemia in this vulnerable population.

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

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,...

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...

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Oral Hypoglycemic Agents: Biguanides and Glitazones01:26

Oral Hypoglycemic Agents: Biguanides and Glitazones

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...
