Pharmacokinetics in Pediatric Patients: Drug Metabolism

330
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

4.8K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Cystic Fibrosis: Pathogenesis

1.0K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Pulmonary Hypertension: Classification and Pathogenesis

843
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Area of Science:

  • Cellular Biology
  • Pulmonary Medicine
  • Molecular Biology

Background:

  • Proteostasis maintains cellular health by controlling protein synthesis, folding, and degradation.
  • Dysregulation of proteostasis is increasingly recognized as a key factor in chronic lung diseases.

Purpose of the Study:

  • To introduce the concept of proteostasis.
  • To review the evidence linking proteostasis dysregulation to chronic lung diseases in pediatric and adult populations.

Main Methods:

  • Literature review of proteostasis pathways.
  • Analysis of existing evidence on proteostasis in lung disease pathogenesis.

Main Results:

  • Impaired proteostasis is implicated in both adult and pediatric chronic lung diseases.
  • This includes sporadic conditions and hereditary disorders like cystic fibrosis and alpha-1 antitrypsin deficiency.

Conclusions:

  • Understanding proteostasis pathways provides novel therapeutic strategies for chronic lung diseases.
  • Targeting proteostasis may offer new treatments for lung conditions in young and adult patients.
