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...
Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
CRISPR01:59

CRISPR

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...
Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...
Diabetes Mellitus: Type 2 and Gestational01:22

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...
Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids01:25

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Medicine
  • Pharmacology

Background:

  • Antenatal steroid administration is standard for women at risk of preterm delivery before 32-34 weeks' gestational age.
  • Recent meta-analyses (up to 2007) by the Cochrane Collaboration have summarized benefits, steroid choice, dosing, and repeat doses.
  • Despite established benefits, significant uncertainties persist regarding optimal steroid selection, dosage, and application in specific patient groups.

Purpose of the Study:

  • To review and clarify areas of uncertainty regarding antenatal corticosteroid therapy for preterm delivery.
  • To guide clinical practice on the choice of steroid, optimal dosing strategies, and use in selected high-risk populations.

Main Methods:

  • Literature review focusing on recent meta-analyses and addressing specific clinical questions.
  • Synthesis of available evidence on the benefits, risks, and uncertainties of antenatal corticosteroids.

Main Results:

  • Established benefits of antenatal steroids for fetal lung maturation and reduction of neonatal morbidity and mortality.
  • Identified gaps in knowledge concerning the comparative effectiveness of different corticosteroids (e.g., betamethasone, dexamethasone).
  • Highlighted the need for evidence-based guidelines on repeat dosing and use in diverse maternal and fetal conditions.

Conclusions:

  • While antenatal steroids are beneficial, precise recommendations for specific steroid agents, optimal dosing regimens, and use in nuanced clinical scenarios require further investigation.
  • Further research is needed to refine protocols for antenatal corticosteroid therapy, ensuring maximal benefit and safety for at-risk pregnancies.
  • Addressing these uncertainties will optimize the management of preterm birth and improve neonatal outcomes.
