Insights

Abnormal early amplitude-integrated electroencephalography (EEG) in premature infants strongly predicts severe brain lesions. This screening tool aids in early detection of neonatal brain abnormalities in very low birth weight infants.

Area of Science:

  • Neonatal neurology
  • Neurophysiology
  • Pediatric imaging

Background:

  • Very low birth weight (VLBW) infants are at high risk for neonatal brain injury.
  • Early detection of brain lesions is crucial for timely intervention in VLBW infants.

Purpose of the Study:

  • To determine the association between abnormal early amplitude-integrated electroencephalography (EEG) and severe brain lesions in VLBW infants.
  • To assess the utility of amplitude-integrated EEG as a screening tool for neonatal brain lesions.

Main Methods:

  • Amplitude-integrated EEG was performed within 48 hours of birth in 70 VLBW infants.
  • Neonatal brain lesions were assessed using magnetic resonance imaging (MRI) and ultrasonography (US).
  • Statistical analyses included the χ² test and analysis of variance; sensitivity, specificity, and positive likelihood ratio were calculated.

Main Results:

  • A significant relationship (P < .001) was found between abnormal amplitude-integrated EEG background and severe MRI/US lesions.
  • Sensitivity and specificity for detecting severe lesions were 100% and 89%, respectively.
  • Adverse outcomes were observed in 6 patients.

Conclusions:

  • Early amplitude-integrated EEG with moderate/severe background abnormalities is linked to severe structural brain lesions in VLBW infants.
  • Amplitude-integrated EEG can serve as an effective auxiliary screening tool for identifying neonatal brain lesions in this vulnerable population.

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...

Pulse amplitude and quality01:17

Pulse amplitude and quality

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Weighted Mean00:57

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...

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...

Apparent Weight01:09

Apparent Weight

True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.
Consider a person standing on a bathroom scale inside an elevator. If the scale is accurate at rest, its reading equals the...
