Natural History Study
A natural history study is a preplanned intended to track the course of the disease. Its purpose is to identify demographic, genetic, environmental, and other variables (e.g., treatment modalities, concomitant medications) that correlate with the disease’s development and outcomes. Natural history studies are likely to include patients receiving the current standard of care and/or emergent care, which may alter some manifestations of the disease.
Genetically Modified Organism (GMO)
A genetically modified organisme (GMO) is an organism whose genetic material has been altered in a way that does not occur naturally through mating or natural recombination.In the context of biotechnology and agriculture, GMOs are typically created by inserting or deleting genes in the DNA of plants, animals, or microorganisms in order to enhance desirable traits, such as increased resistance to pests or improved nutritional content.The use of GMOs has been controversial due to concerns about the potential risks and unintended consequences of genetically modifying organisms, including the possibility of unintended harm to human health or the environment.In some countries, including the European Union, GMOs are subject to strict regulations, and the use of GMOs in food production is restricted or prohibited. In other countries, such as the United States, GMOs are widely used in agriculture and food production, and are subject to regulatory oversight by agencies such as the FDA and the U.S. Departement of Agriculture (USDA). Overall, the use of GMOs remains a topic of debate and controversy, with proponents and opponents both citing scientific evidence and ethical considerations in support of their respective positions.
