Longitudinal Research02:20

Longitudinal Research

12.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Preclinical Development: Overview

5.3K
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

207
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Area of Science:

  • Animal Welfare Science
  • Laboratory Animal Science
  • Regulatory Science

Background:

  • Ensuring the long-term welfare of research animals is crucial for scientific progress and ethical practice.
  • Limited global guidance exists on cumulative and experimental endpoints for research animals.
  • Current practices for monitoring animal welfare and defining endpoints vary significantly.

Purpose of the Study:

  • To explore current institutional strategies and opinions on cumulative use and endpoints for research animals.
  • To review existing regulations and welfare assessment tools related to animal research.
  • To provide recommendations for assessing the cumulative and lifetime use of research animals.

Main Methods:

  • Conducted a scoping survey of institutions regarding their policies and practices for cumulative use endpoints.
  • Reviewed current national and international regulations pertaining to research animal welfare.
  • Assessed existing welfare assessment tools used in animal research settings.

Main Results:

  • Only 36% of surveyed institutions reported having formal cumulative use endpoint policies, with many being informal or species-specific.
  • A majority of respondents favored clearer guidelines but expressed concerns about rigid policies hindering case-by-case assessments.
  • Significant diversity in research animal use complicates the implementation of uniform policies.

Conclusions:

  • Objective endpoint decisions necessitate standardized and robust welfare assessment tools.
  • Further research is needed to develop efficient welfare assessment tools to support cumulative endpoint planning.
  • Recommendations focus on improving the assessment of cumulative and lifetime use for research and teaching animals.
