Lipid-Lowering Drugs: Statins and Miscellaneous Agents01:20

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

1.7K
Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Lipid-derived Compounds in the Human Body

5.5K
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,...

Lipid Absorption01:24

Lipid Absorption

3.9K
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...

Lipid Digestion01:06

Lipid Digestion

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

Pharmacokinetics in Pediatric Patients: Drug Distribution

554
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,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

967
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Summary
This summary is machine-generated.

Small-quantity lipid-based nutrient supplements (LNS) did not reduce breast milk intake in Malawian infants aged 9-10 months. This finding supports the use of LNS as complementary foods without compromising breastfeeding.

Area of Science:

  • Nutrition Science
  • Infant Health
  • Public Health

Background:

  • Investigating the impact of small-quantity lipid-based nutrient supplements (LNS) on infant growth and development.
  • Concerns exist that LNS may reduce breast milk intake, potentially diminishing its benefits.

Purpose of the Study:

  • To test if breast milk intake is lower in 9- to 10-month-old Malawian infants receiving LNS compared to unsupplemented infants.
  • Hypothesis: LNS supplementation does not decrease breast milk intake.

Main Methods:

  • Substudy of the iLiNS DOSE trial involving infants aged 6-18 months.
  • Infants received 10, 20, or 40 g LNS/d or no LNS.
  • Breast milk intake measured at 9-10 months using the deuterium oxide dilution method.

Main Results:

  • No significant difference in breast milk intake between supplemented and unsupplemented infants.
  • Mean daily breast milk intake for controls was 730 ± 226 g.
  • Supplementation with 10-40 g LNS/d did not lead to a statistically significant reduction in breast milk intake.

Conclusions:

  • Breast milk intake at 9-10 months of age was not reduced by 10-40 g/d of LNS supplementation in rural Malawian infants.
  • LNS can be safely introduced as complementary foods without negatively impacting breastfeeding duration or volume.
