Insights

New growth standards are needed for preterm infants to improve neonatal care. These standards should be based on healthy infants to ensure accurate monitoring and evidence-based clinical practices.

Area of Science:

  • Neonatology
  • Pediatric Growth Monitoring

Background:

  • Current growth charts for preterm infants may not be appropriate for modern neonatal care.
  • There is a need for updated, robust standards to accurately interpret preterm infant growth.

Purpose of the Study:

  • To propose the development of new international prescriptive growth standards for preterm infants.
  • To establish standards based on a carefully selected population of healthy preterm infants.

Main Methods:

  • Define criteria for selecting preterm infants for new standards: no impaired fetal growth, born to low-risk mothers, precise gestational age dating.
  • Exclude infants with congenital malformations or conditions affecting postnatal growth.
  • Ensure infants receive standardized, evidence-based care and follow current feeding recommendations.

Main Results:

  • The proposed methodology aims to create a population dataset conceptually similar to WHO growth standards.
  • This approach will yield new, evidence-based international standards for preterm infant growth.

Conclusions:

  • Developing new prescriptive growth standards is crucial for advancing the evidence-based care of preterm infants.
  • These standards will enhance the accuracy and appropriateness of growth monitoring in neonatal settings.

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, such as differences...
Nursing Evaluation01:15

Nursing Evaluation

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to exist...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
Guidelines for Writing Outcome01:11

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care evaluation by...
