Summary
Diaphragmatic ultrasound revealed impaired function in newborns with transient tachypnea (TTN) compared to healthy infants. Diaphragmatic excursion was lower in TTN cases, suggesting pulmonary disease impacts diaphragm activity.
Area of Science:
- Neonatal Medicine
- Respiratory Physiology
- Diagnostic Imaging
Background:
- The role of diaphragmatic function in transient tachypnea of the newborn (TTN) is not well understood.
- Neonates with TTN often require non-invasive ventilation (NIV).
Purpose of the Study:
- To compare diaphragmatic ultrasound parameters between neonates with TTN requiring NIV and healthy neonates.
- To explore relationships between diaphragmatic parameters, gestational age (GA), and birth weight (BW).
- To assess inter-operator reproducibility of measurements.
Main Methods:
- Prospective observational pilot study including neonates with GA ≥ 34 weeks.
- Diaphragmatic and lung ultrasound performed on day 1 (T0) and day 2 (T1).
- Measurements: diaphragmatic thickness (DTi, DTe), diaphragmatic excursion (DE), Lung Ultrasound Score (LUS).
Main Results:
- Forty neonates enrolled (20 TTN, 20 controls).
- Diaphragmatic excursion (DE) was significantly lower in TTN neonates versus controls (p=0.03).
- DE increased in controls from T0 to T1, but not in TTN cases; DE negatively correlated with LUS (p=0.05).
Conclusions:
- Pulmonary disease in TTN may influence diaphragmatic function.
- Integrating lung and diaphragmatic ultrasound can aid in monitoring TTN progression and follow-up.

01:29Reliability and Validity
13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

In a series resistor-inductor (R-L) circuit, closing the switch at the start of the time period simulates a three-phase short circuit, a fault condition where all three phases of an unloaded synchronous machine are short-circuited. When there is no fault impedance and no initial current, the initial voltage is determined by the phase angle of the source voltage.

The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

The concept of real numbers includes all the values that can be represented on a continuous number line. The system began with basic counting values used for enumeration. It later expanded to include values that represent the absence of quantity and opposites of the counting values. When situations required expressing parts of a whole or dividing quantities evenly, values capable of representing such proportions were developed. When written using decimal notation, these values can end or repeat...
