What are Estimates?01:06

What are Estimates?

8.8K
It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate the mean height or mean weight of the individuals in the sample. This sample data acts as a representative measure of the population parameter. These sample statistics are known as estimates. 
The estimate for the mean of a sample is denoted by ͞x, whereas the mean of the population is designated as μ. Further, parameters such...

One-Compartment Open Model for IV Bolus Administration: Estimation of Elimination Rate Constant, Half-Life and Volume of Distribution

897
The one-compartment open model is a simplified approach used in pharmacokinetics to understand the distribution and elimination of a drug administered through an intravenous bolus. This model assumes rapid drug dispersal throughout the body and elimination using a first-order process. Key pharmacokinetic parameters, such as the elimination rate constant (k), half-life (t1/2), and the apparent volume of distribution (Vd), can be estimated from this model. The elimination rate is calculated...

Estimation of k and VD of Aminoglycosides01:20

Estimation of k and VD of Aminoglycosides

249
Aminoglycosides are a class of antibiotics used to treat various bacterial infections. Clinicians must determine the elimination rate constant (k) and volume of distribution (VD) to optimize therapeutic efficacy and minimize toxicity. The k value represents the rate at which the drug is removed from the body, and the VD reflects the degree to which the drug distributes into body tissues. Accurately estimating these parameters allows healthcare professionals to tailor drug dosing to individual...

Constant Volume Calorimetry02:41

Constant Volume Calorimetry

30.8K
Calorimeters are useful to determine the heat released or absorbed by a chemical reaction. Coffee cup calorimeters are designed to operate at constant (atmospheric) pressure and are convenient to measure heat flow (or enthalpy change) accompanying processes that occur in solution at constant pressure. A different type of calorimeter that operates at constant volume, colloquially known as a bomb calorimeter, is used to measure the energy produced by reactions that yield large amounts of heat and...

Volume of Distribution01:20

Volume of Distribution

1.3K
The apparent volume of distribution (Vd) is a crucial pharmacokinetic parameter representing the hypothetical body fluid volume into which a drug disperses. It is calculated based on the total amount of drug in the body (estimated from the administered dose and bioavailability) divided by the plasma drug concentration. The total amount of drug in the body does not directly refer to the dose given but is derived by accounting for absorption, distribution, metabolism, and excretion processes.

Problem Solving: Volume

77
The volume of a fuel tank mounted on the wing of a jet aircraft can be modeled using the concept of solids of revolution. In this case, the tank is formed by rotating a two-dimensional region, defined by a mathematical function, about the x-axis. The region extends along the axis from zero to two meters, and the resulting three-dimensional shape is symmetric about the axis of rotation. Because the boundary curve lies directly against the axis, the disk method is an appropriate technique for...

Area of Science:

  • Medical imaging
  • Surgical oncology
  • Radiology

Background:

  • Current breast volume measurement methods have limitations due to assumptions of fixed breast shapes.
  • Accurate breast volume estimation is crucial for surgical planning, including oncoplastic breast surgery and breast reduction.

Purpose of the Study:

  • To develop and validate a novel, computer-aided digital method for estimating breast volume.
  • To compare the accuracy of this new method against existing techniques and actual breast volume.

Main Methods:

  • A new digital breast volume estimation technique was developed using mammographic data (craniocaudal and mediolateral oblique views).
  • The method calculates volume based on breast area and dimensions, utilizing AGFA® Impax™6 software.
  • The technique was validated by comparing its estimations with three established methods and, in 15 mastectomy patients, with fresh mastectomy weights.

Main Results:

  • The digital breast volume estimation method showed significant correlation with existing techniques across 50 patients.
  • The craniocaudal (CC) view demonstrated the best correlation with established methods.
  • In mastectomy patients, the digital technique showed good correlation with actual breast volume (mastectomy weight).

Conclusions:

  • A novel, simple, and accurate digital tool for estimating breast volume has been developed.
  • This method has the potential to improve surgical planning for oncoplastic breast cancer surgery and breast reduction procedures.
