Study Notes

Medical Research Introduction

Medical research aims to understand and treat diseases, improving human health.
Effective research relies on reliable and valid findings generalizable to the target population.
Critical factors include appropriate sample size and representative participants.
Medical research, also known as health research, uses scientific methods to understand diseases, prevention, treatment, and health promotion.
It encompasses a spectrum from basic research (bench science) to clinical trials and translational research.

History of Medical Research

Clinical trials' history stretches back to biblical accounts (500 BCE).
Early trials involved dietary therapies (e.g., legumes, lemons).
Approaches to clinical trials refined in the 18th century, with advancements in design and statistics.
Ethical and regulatory frameworks evolved alongside clinical trial methodologies.

Pre-James Lind Era (562 BCE - 1537)

The first recorded clinical trial is described in the Book of Daniel (biblical).
Nebuchadnezzar's experiment involved diets and observations on physical health.
Avicenna, in the 11th century, outlined rules for drug testing, suggesting concepts relevant to modern clinical trials.

James Lind and Scurvy Trial (1747)

James Lind conducted a controlled clinical trial for scurvy.
He studied different treatments on sailors, comparing various treatments to identify effective ones.
His trial highlighted the importance of detailed record keeping and standardized protocols in research.
He documented the effectiveness of citrus fruits (oranges and lemons) in treating scurvy.

Arrival of Placebo (1800s)

The concept of a placebo emerged in the 1800s, defined as a treatment with no inherent therapeutic value, used in controlled experiments.

Ethical and Regulatory Framework Evolution

Ethical frameworks for human subject protection developed over time, rooted in ancient principles like the Hippocratic Oath.
Key milestones include the Nuremberg Code (1947) which emphasized voluntary informed consent in research.
Additional milestones include the Declaration of Helsinki (1964) and relevant regulations for clinical testing in different countries..

Evolution of Clinical Trials in India

India has a rich history of traditional medicine that likely involved observational treatments.
The development of modern clinical trials in India reflects the evolving regulatory and ethical frameworks.
Notably, challenges to integrating India's early clinical trials with global standards were discussed related to phases and regulations.

Contemporary Clinical Trials

Contemporary clinical trials use standardized procedures focusing on scientific assessment of drug efficacy, patient safety, and balancing medical progress.
Continuing ethical considerations and regulatory updates are vital aspects of ensuring the responsible conduct of research.
