Insights

Low HDL-cholesterol (HDL-C) levels in Brazilian children were linked to inflammation and obesity indicators. High non-HDL-cholesterol (nHDL-C) was associated with abdominal obesity, darker skin color, and higher income.

Area of Science:

  • Pediatric Cardiology
  • Lipid Metabolism
  • Public Health

Background:

  • High-density lipoprotein cholesterol (HDL-C) and non-HDL-cholesterol (nHDL-C) play roles in atherosclerosis.
  • Understanding their distribution in pediatric populations is crucial for early cardiovascular risk assessment.

Purpose of the Study:

  • To determine the distribution of HDL-C and nHDL-C in a Brazilian pediatric sample.
  • To investigate associations between HDL-C and nHDL-C levels and cardiovascular and socio-cultural variables.

Main Methods:

  • Random selection of children and adolescents from Florianopolis.
  • Administration of questionnaires, physical examinations, and blood sample collection.
  • Enzymatic and Direct methods for cholesterol level determination; logistic regression for association analysis.

Main Results:

  • 23% of participants had low HDL-C, and 25% had high nHDL-C.
  • Low HDL-C associated with high C-reactive protein, paternal tobacco use, and high triceps-to-subscapular index.
  • High nHDL-C associated with high waist circumference, black skin color, and high income.

Conclusions:

  • Low HDL-C levels in this pediatric sample were linked to clinical factors like C-reactive protein and a centripetal fat pattern.
  • High nHDL-C levels were associated with abdominal obesity, skin color, and economic class.

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
Lipid Absorption01:24

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
