Insights

Maternal smoking and gestational hypertension are key risk factors for intrauterine growth retardation (IUGR). Most infants with IUGR achieved catch-up growth by 12 months, but vigilance for hypoglycemia is crucial.

Area of Science:

  • Neonatalogy
  • Perinatology
  • Pediatric Growth and Development

Background:

  • Intrauterine growth retardation (IUGR) describes fetuses failing to reach their genetic growth potential.
  • Lack of international consensus on IUGR definition complicates research and clinical practice.
  • This study describes a cohort of neonates with restricted growth, focusing on maternal risk factors and neonatal outcomes.

Purpose of the Study:

  • To describe a cohort of neonates with intrauterine growth retardation (IUGR).
  • To identify maternal risk factors associated with IUGR.
  • To evaluate neonatal outcomes, including growth catch-up and neurological development, up to 12 months of age.

Main Methods:

  • Retrospective descriptive study of 73 neonates with birth weight below the 70th percentile.
  • Data collected on maternal and obstetrical risk factors.
  • Neonatal growth and outcomes assessed at 6 weeks, 5 months, and 12 months.

Main Results:

  • Caesarean delivery was common (78%).
  • Maternal risk factors included gestational hypertension (33%), smoking (24%), and placental infarction (17%).
  • 31% of neonates experienced hypoglycemia; 90% achieved catch-up growth by 12 months, with 7% having poor neurological outcomes. No deaths occurred.

Conclusions:

  • Maternal smoking and gestational hypertension are significant IUGR risk factors.
  • Preventing hypoglycemia in IUGR infants requires special attention.
  • A consensus on IUGR definition and follow-up is needed for comparable research.

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...

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...

Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Infertility in Females01:28

Infertility in Females

Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...
