Study Notes

Thalidomide Disaster and Research Standards

Thalidomide: A medication associated with severe birth defects when taken during pregnancy.
Animal Welfare Principles: Emphasizes the ethical treatment of animals in research through the 3Rs: Reduction, Refinement, Replacement.

Reduction, Refinement, Replacement

Reduction: Utilize optimal sample size calculations to minimize animal use in research.
Refinement: Procedures must aim to minimize harm and distress to animals.
Replacement: Research should demonstrate that no alternative in vitro model can substitute for animal testing.

Clinical Research

Characteristics: Involves epidemiological and behavioral studies to assess disease prevalence, incidence, and health-related decisions.

Clinical Trials

Purpose: Evaluate safety and effectiveness of new drugs, devices, and behavioral interventions on human subjects.
Phases of Clinical Trials:
- Phase 1: Focuses on safety in healthy subjects.

Safety and Ethics

Informed Consent: Essential for protecting participants' rights and welfare during research.
Good Clinical Practice: Certification necessary before conducting clinical studies.
Potential Ethical Concerns: Deliberate infection of patients in vaccine trials to test efficacy raises significant ethical issues.

Scientific Fraud

Definition: Misconduct in research including predatory journals that publish unreviewed studies.
Notable Case: John Bohannon’s investigation highlighted lack of peer review in open-access journals.
Common Examples:
- Copying and pasting from other journals.
- Misrepresentation of authorship.
- Manipulation of statistical results to appear significant.

Ethical Considerations in Human Studies

Human Challenge Studies: Requires weighing benefits against risks, particularly where disease risk is high and incurable.

Five Freedoms in Animal Welfare

Freedom from Thirst, Hunger, and Malnutrition
Freedom from Physical Discomfort and Pain
Freedom from Injury and Disease
Freedom to Conform to Essential Behavior Patterns
Freedom from Fear and Distress

Personalized Medicine

Customization: Personalized approaches are encouraged in medicine, but entail careful consideration of ethical aspects.
