CRISPR01:59

CRISPR

53.6K
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...

Teratogenicity

3.2K
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...

Summary
This summary is machine-generated.

Navigating care for extremely preterm infants requires updated data beyond simple survival. Focusing on disability-free survival and long-term outcomes is crucial for informed decisions in the perinatal and postnatal periods.

Area of Science:

  • Neonatal Medicine
  • Perinatal Care
  • Medical Ethics

Background:

  • Clinicians use gestational age at birth for counseling preterm infants, particularly those near the limits of viability.
  • Current methods for estimating gestational maturity, like first-trimester ultrasounds, have limitations in accuracy (±3-7 days).
  • Outcome data for premature infants are often reported by completed gestational weeks, with significant changes near the viability threshold.

Purpose of the Study:

  • To explore the ethical and medical complexities in decision-making for infants born at the margins of viability (less than 25 weeks gestation).
  • To identify knowledge gaps and suggest future research directions for optimizing care.
  • To propose a perspective for collaborative decision-making and care for extremely preterm infants.

Main Methods:

  • Review of contemporary clinical practices and published literature on preterm infant outcomes.
  • Analysis of the shift in focus from survival to disability-free and long-term functional outcomes.
  • Exploration of ethical considerations in perinatal and postnatal care.

Main Results:

  • Decision-making for extremely preterm infants (<25 weeks gestation) is complex, involving survival, disability-free survival, and long-term functional outcomes.
  • Postnatal support requires optimizing growth, nutrition, and organ repair to mitigate risks of preterm birth.
  • Current knowledge has gaps regarding optimal strategies for supporting maturation and long-term well-being.

Conclusions:

  • Ethical and medical challenges persist in managing infants born at the margins of viability.
  • Future research should address knowledge gaps to improve collaborative decision-making and care strategies.
  • A focus on optimizing growth and development alongside life support is essential for extremely preterm infants.
