Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

293
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Methods for Studying Drug Absorption: In vitro01:16

Methods for Studying Drug Absorption: In vitro

607
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

Methods for Studying Drug Absorption: In situ

676
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

Exercise and Muscle Performance01:27

Exercise and Muscle Performance

2.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Pathophysiology of Cardiac Performance01:29

Pathophysiology of Cardiac Performance

1.5K
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...

Area of Science:

  • Pediatric Nutrition
  • Developmental Biology
  • Oral Physiology

Background:

  • Assessing masticatory performance in infants and toddlers is crucial for understanding oral development and feeding behaviors.
  • Existing methods like chew-and-spit may be unfeasible for this age group.
  • Early masticatory development influences food texture acceptance and overall nutrition.

Purpose of the Study:

  • To evaluate the feasibility of a novel method for quantifying masticatory performance in infants and toddlers (6-18 months).
  • To assess the relationship between masticatory performance, age, oral processing strategies, and dentition.
  • To provide a practical tool for future research on early food oral processing.

Main Methods:

  • A gel-comminution method using a mesh feeder was employed with 97 healthy children aged 6-18 months.
  • Masticatory performance was assessed by analyzing gel particle size and number after 60s of oral processing.
  • Children's oral processing strategies (sucking vs. biting/chewing) and compliance were recorded via video.

Main Results:

  • Masticatory performance, indicated by increased particle number and area, significantly improved with age.
  • Children's compliance with the feeder averaged 51%, decreasing after 12 months of age.
  • Particle area was associated with sucking behavior, while teeth emergence showed no significant association.

Conclusions:

  • The developed gel-comminution method is a feasible and relevant tool for quantifying masticatory performance development in young children.
  • The method provides objective data on early masticatory abilities, aiding in understanding oral processing and food acceptance.
  • Compliance data offers practical guidance for optimizing the application of this method in future studies.
