Breath Analysis and Malnutrition Study

This research study is looking at how your breath might be connected to your nutritional health. We want to see if specific molecules in your breath, like ammonia, change when you have malnutrition. We'll compare breath samples from people with and without malnutrition, and also look at how breath changes after short periods of eating special nutrition drinks or fasting (not eating, only drinking water). If you join, you'll provide blood and breath samples, answer questions about your health and diet, and have a physical exam. This study aims to find early signs of malnutrition using breath analysis. We are looking for 12 participants aged 18 to 95 years old who have been diagnosed with malnutrition. The study status is currently unclear.

Study design
This is an interventional study, meaning some participants will receive specific interventions like nutrition beverages or fasting. It also includes a cross-sectional part comparing people with and without malnutrition.
What's involved
You will provide blood and breath samples, answer questionnaires about your health, medications, nutritional status, and diet, and have a physical examination. Some participants will also consume study beverages or fast for two days and provide additional breath samples.
Compensation
Not stated in the trial record.
Follow-up
Breath ammonia will be measured upon waking and after the intervention, but before bed on each of the 1-day intervention arms.
