Bioavailability Study Design: Healthy Subjects Versus Patients

210
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,...

Clinical Trials

11.2K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Clinical Trials: Overview

5.5K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Study Designs in Epidemiology

1.6K
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Integrated Healthcare System

2.6K
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Area of Science:

  • Public Health
  • Nutrition Science
  • Digital Health

Background:

  • Health data collection for college students and graduates in nutrition is essential.
  • Existing methods may be costly, time-consuming, or less accessible.
  • There is a need for efficient and reliable tools for longitudinal health monitoring in this demographic.

Purpose of the Study:

  • To develop and evaluate the e-NutriHS, a web-based system for collecting online health information.
  • To assess the feasibility and reliability of using a digital platform for health data acquisition in a specific cohort.
  • To share the experience of developing and deploying such a system, particularly for middle-income countries.

Main Methods:

  • Development of a web-based system (e-NutriHS) utilizing free programming languages.
  • Integration of six validated and internationally recognized questionnaires covering demographics, lifestyle, and health history.
  • Prototyping, user feedback incorporation from 20 volunteers, and subsequent online deployment.
  • Hosting the system and database on a School of Public Health server.

Main Results:

  • A total of 503 users registered in the e-NutriHS system.
  • The system incorporates validated questionnaires on crucial health indicators.
  • The development process included iterative improvements based on user feedback.

Conclusions:

  • Web-based systems like e-NutriHS provide reliable, user-friendly, cost-effective, and time-efficient health data collection.
  • The experience with e-NutriHS is valuable and transferable, especially to middle-income economies.
  • Digital health platforms are a viable solution for monitoring the health of student and graduate populations.
