Pharmacokinetic Models: Comparison and Selection Criterion

Pharmacokinetic Models: Comparison and Selection Criterion

Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.

The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

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...

Renal Drug Clearance: Comparison Between Renal Excretion Methods

Renal Drug Clearance: Comparison Between Renal Excretion Methods

Renal clearance is a critical parameter encompassing kidney filtration, secretion, and reabsorption processes. It is calculated using a specific equation to determine the rate at which the kidneys clear a drug.
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Background:

Radiotherapy (RT) for lung cancer can cause significant toxicities, impacting patient quality of life.
Accurate prediction of RT-induced toxicity is crucial for personalized treatment planning.
Identifying relevant predictive parameters remains a challenge in lung cancer radiotherapy.

Purpose of the Study:

To conduct a scoping review of Feature Selection (FS) methods for predicting RT-induced toxicity in lung cancer patients.
To elucidate the relevance of different parameters in predicting specific toxicities.
To identify optimal FS methods for improving toxicity prediction models.

Main Methods:

A scoping review methodology was employed.
Subsetting-based and Ranking-based FS methods were implemented.
Four advanced classifiers were utilized to predict acute esophagitis, cough, pneumonitis, and dyspnea.
Area Under the Curve (AUC) was used to measure prediction performance.

Main Results:

Various FS methods were evaluated for their effectiveness in identifying predictive parameters for RT-induced toxicities.
The performance of different classifiers in predicting specific toxicities was compared.
The study identified FS approaches that showed promise in enhancing prediction accuracy.

Conclusions:

Feature selection is a vital step in developing accurate predictive models for radiotherapy-induced toxicities.
The choice of FS method can significantly influence the identification of relevant parameters and model performance.
Further research is warranted to optimize FS strategies for personalized lung cancer radiotherapy.
