Parentral Nutrition: Centeral and Peripheral Parental Nutrition01:27

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Dosage Regimen: Individualization01:24

Dosage Regimen: Individualization

Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...
Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
Chronic Kidney Disease III: Interprofessional Care01:28

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu01:29

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Summary

Genotype-based nutrition shows promise for preventing chronic diseases by linking genetic information to dietary advice. However, small gene variant effects and lack of intervention studies limit its current application.

Area of Science:

  • Nutrigenomics
  • Personalized Nutrition
  • Chronic Disease Prevention

Background:

  • Personalized, genotype-based nutrition aims to prevent chronic diseases by connecting genetic data with specific dietary recommendations.
  • While genetic variations can influence nutrient responses, their impact on complex diseases is often minor and inconsistent.
  • Current understanding of genotype-diet interactions is limited, necessitating further research.

Purpose of the Study:

  • To review the scientific basis of genotype-based nutrition.
  • To discuss the challenges and limitations of implementing personalized nutrition strategies.
  • To identify areas requiring further investigation before widespread adoption.

Main Methods:

  • Literature review of scientific evidence on genotype-based nutrition.
  • Analysis of studies investigating gene-nutrient interactions.
  • Discussion of challenges in predictive precision and causality.

Main Results:

  • Convincing evidence exists for gene variants affecting biological responses to nutrients.
  • Single-gene variant effects on complex disease risk are typically small and inconsistent.
  • Few genotype-response associations have been causally tested in human intervention studies.

Conclusions:

  • Combinations of gene variants may be needed to enhance predictive accuracy in personalized nutrition.
  • More research is required to establish causality and assess potential adverse effects of genotype-guided interventions.
  • Genotyping is not yet a sufficiently validated method for guiding general nutritional recommendations.
