Clinical Trials: Overview01:11

Clinical Trials: Overview

3.7K
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...

Clinical Trials

9.5K
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...

Preclinical Development: Overview01:28

Preclinical Development: Overview

5.1K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

Exercise and Cardiovascular Response01:20

Exercise and Cardiovascular Response

1.2K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Exercise and Muscle Performance01:27

Exercise and Muscle Performance

1.7K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Exercise Stress Test01:26

Exercise Stress Test

563
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Area of Science:

  • Exercise Oncology
  • Preclinical Research
  • Translational Science

Background:

  • Preclinical studies are vital for developing new cancer treatments.
  • Monitoring cancer-induced complications in preclinical exercise oncology is essential.
  • Bridging the gap between preclinical and clinical exercise oncology is a key challenge.

Purpose of the Study:

  • To review exercise protocol design in preclinical exercise oncology studies.
  • To identify strategies for closing the preclinical-clinical gap in exercise oncology.
  • To examine exercise-responsive outcomes in preclinical versus clinical settings.

Main Methods:

  • A literature search was conducted in PubMed/Medline.
  • Animal studies in exercise oncology were reviewed.
  • English-language studies were screened.

Main Results:

  • Most preclinical exercise protocols have not been clinically tested.
  • Some preclinical outcomes (e.g., cellular adaptation markers) translate to clinical studies.
  • Successful translation depends on suitable and applicable preclinical exercise protocols.

Conclusions:

  • Cancer and treatment complications are often overlooked in preclinical exercise oncology protocols.
  • Preclinical studies must consider clinical limitations for translatable findings.
  • Designing feasible preclinical protocols, considering patient compliance and adverse effects, is key to bridging the gap.
