Insights

Obese children show signs of oxidative stress, indicated by higher oxidant capacity and lower antioxidant capacity. Early intervention is crucial to prevent long-term health issues related to free radical damage.

Area of Science:

  • Pediatrics
  • Biochemistry
  • Metabolic Disorders

Background:

  • Obesity is linked to increased free radical production.
  • Uncontrolled free radicals can cause oxidative stress and health complications.
  • The presence of oxidative stress in obese prepubertal children requires investigation.

Purpose of the Study:

  • To evaluate the presence and extent of oxidative stress in obese prepubertal children.
  • To compare oxidative stress markers between obese and nonobese children.

Main Methods:

  • The study included 83 children aged 2-10 years (62 obese, 21 controls).
  • Serum levels of total oxidant capacity (TOC), total antioxidant capacity (TAC), oxidized low-density lipoprotein (ox-LDL), lipids, glucose, and C-reactive protein (CRP) were measured.
  • Oxidative stress index (OSI) was calculated.

Main Results:

  • Obese children exhibited significantly higher TOC and lower TAC compared to controls.
  • The oxidative stress index (OSI) was significantly higher in the obese group.
  • Obese children had higher median CRP and lower HDL cholesterol levels. TAC negatively correlated with ox-LDL, and obesity duration positively correlated with TOC.

Conclusions:

  • Obesity-related oxidative stress is present even in prepubertal children.
  • Early diagnosis and treatment of obesity are vital for preventing free radical damage and associated complications.

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Radical Autoxidation01:20

Radical Autoxidation

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Oxidation of Phenols to Quinones01:17

Oxidation of Phenols to Quinones

In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...
