Is this trial a fit for you?
✓Likely a good fit
Ideal participants are adults (over 18) hospitalized in the surgical/trauma ICU for more than seven days who are receiving enteral or oral feeding and not on prior TPN, plus healthy adult volunteers for the control group.
✕Probably not a fit
Patients under 18, those who were on total parenteral nutrition before ICU admission, those with chronic bowel disease, and relatives or staff of the investigators are excluded and unlikely to benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This trial compares amino acid handling in 15 adult surgical or trauma ICU patients who have been hospitalized for more than seven days with 15 healthy adult volunteers. Participants receive a labeled amino acid tracer injection and researchers measure tracer kinetics to determine rates of amino acid metabolism and muscle protein turnover. The study excludes patients under 18, those previously on total parenteral nutrition, and those with chronic bowel disease, and is conducted at Rabin Medical Center with collaboration from Texas A&M University. Results aim to clarify metabolic changes associated with ICU-acquired weakness and sarcopenia in the fed state.
Why it matters
Potential benefit: If successful, the findings could improve understanding of muscle wasting in critically ill surgical patients and help guide better nutrition or therapy to preserve muscle.
How similar studies have gone: Stable-isotope amino acid tracer studies have been used successfully to measure amino acid kinetics in critically ill and healthy people, though translating metabolic findings into effective clinical treatments has been limited.
