The Serum Measurements for Nutrition Standard Measures test battery measures the cortisol levels in blood samples obtained from subjects. Cortisol plays a role in several systems in the body including: stress responses, immune system, nervous system, circulatory system, skeletal system, and the breakdown of proteins, fats, and lipids. The purpose of the standard measures project is to populate a repository with data that enables high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes. The Serum Measurements for Nutrition Standard Measures test battery is one of three Standard Measures (SM) test batteries conducted at Russia’s Institute for Biomedical Problems’ (IBMP) Nazemnyy eksperimental’nyy kompleks (NEK) facility. The NEK standard measures will support future, hypothesis-driven research that enables planetary missions by providing an optimized minimal set of measures captured from subjects. These measures will be available to other studies under data sharing agreements as well as undergo analysis to understand risk posture.
Serum cortisol will be assessed pre-flight, in-flight, and post-flight to minimally assess general stress response. The blood collection for this test will be at the same time in the morning for each of the five collections because there are known fluctuations throughout the day in healthy subjects.
The Serum Measurements for Nutrition Standard Measures will be taken during these approximate times frames:
The NEK Standard Measures Test Battery is not a hypothesis-driven study, but rather a collection of data made available to future researchers and for trend analysis. As such, there are no specific hypotheses, outcome measures, or statistical analyses associated with the skeleton of the project. The questionnaire will capture a "snapshot" of optimized data that can be investigated by researchers in the future.
