    Insights

    Extrauterine growth restriction (EUGR) in very low birth weight (VLBW) infants can impact long-term health. Aggressive nutrition helps, but optimal growth support for preterm infants requires further research.

    Area of Science:

    • Neonatology
    • Pediatric Nutrition
    • Infant Development

    Background:

    • Extrauterine growth restriction (EUGR) is common in very low birth weight (VLBW) infants.
    • EUGR is linked to adverse neurodevelopmental outcomes and long-term health issues.
    • While nutritional strategies have improved, significant questions about optimal growth remain.

    Purpose of the Study:

    • To examine outstanding issues concerning postnatal growth failure in VLBW infants.
    • To review current practice recommendations for supporting infant growth.
    • To address uncertainties in expected growth rates and measurement for preterm infants.

    Main Methods:

    • Review of current literature on EUGR and infant nutrition.
    • Analysis of existing practice guidelines for VLBW infant care.
    • Discussion of challenges in measuring growth velocity in preterm infants.

    Main Results:

    • Aggressive nutritional interventions have decreased postnatal growth failure incidence.
    • Key questions persist regarding ideal growth velocity and measurement methods.
    • Optimal strategies for supporting growth in very preterm infants are still debated.

    Conclusions:

    • Further research is needed to define optimal growth trajectories for preterm infants.
    • Standardized methods for assessing growth velocity are crucial.
    • Evidence-based guidelines are essential for managing EUGR and improving infant outcomes.

    Molecular Weight of Step-Growth Polymers01:08

    Molecular Weight of Step-Growth Polymers

    Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched polymers.
    As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.

    Birth Control Methods

    Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

    Weighted Mean

    While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
    For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

    Restriction Enzymes01:11

    Restriction Enzymes

    Restriction enzymes are bacterial enzymes used to cut DNA in a sequence-specific manner. To cleave DNA, they bind to specific palindromic sequences called restriction sites. Such palindromic DNA sequences or inverted repeats are commonly found in regions of functional significance, such as the origin of replication, gene operator sites, and regions containing transcription termination signals.
    The host bacteria protect their own genomic DNA from these enzymes by methylating these sites. Some...

    Atomic Weight01:25

    Atomic Weight

    Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...

    Mass and Weight01:19

    Mass and Weight

    Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...
