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...
Bioavailability Study Design: Healthy Subjects Versus Patients01:15

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,...
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...

Summary

Personalized nutrition aims to tailor diets using nutrigenomics, but individual responses vary due to genetics and environment. Commercial viability requires addressing consumer and market challenges.

Area of Science:

  • Nutritional Science
  • Genomics
  • Personalized Medicine

Background:

  • Population-based dietary studies show variable individual responses to interventions.
  • Understanding inter-individual variation is key for effective disease risk management.
  • Nutrigenomic technologies offer potential for personalized nutrition strategies.

Purpose of the Study:

  • To review the application of nutrigenomic technologies for personalized nutrition.
  • To assess the process of bringing personalized nutrition to the market.
  • To explore challenges in defining optimal individual dietary responses.

Main Methods:

  • Literature review of nutrigenetics and nutrigenomics studies.
  • Evaluation of current approaches to personalized dietary advice.
  • Analysis of factors influencing individual responses to diet.

Main Results:

  • Defining personalized diets based on single gene variations has proven challenging.
  • Limited understanding of optimal health biomarkers hinders response assessment.
  • Both genetic and environmental factors significantly modulate dietary responses.

Conclusions:

  • Nutrigenomics advances will improve understanding of genotype-phenotype-environment interactions for personalized nutrition.
  • Commercialization of personalized nutrition faces hurdles in consumer acceptance, privacy, and market distribution.
