Predicting mortality through analyzing fecal matter
In a groundbreaking development, researchers from the University of Chicago and the University of Amsterdam have created a tool called the Metabolic Dysbiosis Score (MDS) to predict the risk of mortality within 30 days for patients in intensive care units (ICUs).
The MDS is a metric designed to quantify the imbalance of gut microbiota in critically ill patients, particularly those with conditions like sepsis. It focuses on the trait of dysbiosis, an imbalance where harmful bacteria outnumber beneficial ones, which is common in such patients. The MDS achieves this by analysing the concentrations of 13 distinct fecal metabolites.
Sepsis, a condition that affects patients differently, making it challenging to treat effectively, is often a complication for critically ill patients in ICUs. The MDS offers a potential solution to this diagnostic challenge by targeting the metabolic dysbiosis trait rather than the syndrome as a whole.
The MDS predicts the risk of mortality in ICU patients by indicating how disrupted their gut microbiota and metabolic state are, thus reflecting their body's resilience or vulnerability to severe illness. In a study involving 196 ICU patients with respiratory failure or shock, the MDS showed 84% accuracy, 89% sensitivity, and 71% specificity in predicting mortality.
Butyrate, a metabolite included in the MDS, may play a role in mitigating inflammation and supporting immune function. Other metabolites in the score include short-chain fatty acids (SCFAs) like butyrate, propionate, and acetate, bile acids, and tryptophan metabolites.
SCFAs are produced by the "friendly" bacteria in the gut when fiber is eaten. Inulin, found in onions, leeks, wheat, and asparagus, Fructooligosaccharides (FOS), found in onions, asparagus, and many other fruits and vegetables, especially bananas, pectin found in apples, apricots, carrots, and oranges, and arabinoxylan, found in cereal grains, especially in wheat bran, making up about 70% of the total fiber content, are fiber types that can help produce SCFAs.
Propionate, another metabolite in the MDS, supports brain health and may protect against neurodegenerative diseases like Parkinson's. Acetate, another SCFAs, affects gene expression, metabolic regulation, and enzyme activity.
A high MDS suggests significant physiological distress and a reduced capacity to survive acute illness. Critically ill patients often have reduced diversity in their gut microbiota, which correlates with poor outcomes. The MDS uses specific metabolites to gauge this imbalance, offering a potential tool for tailoring treatments based on individual metabolic and microbiome profiles.
With the MDS, doctors may be able to predict which patients are at a higher risk of mortality and tailor their treatments accordingly, potentially improving outcomes for critically ill patients. Further research is needed to confirm these findings and establish the MDS as a standard tool in ICU care.

- Further research is needed to confirm these findings and establish the MDS as a standard tool in ICU care, contributing to workplace wellness and medical-condition monitoring for chronic diseases like chronic kidney disease, respiratory conditions, and mental health issues, as well as personal growth, education-and-self-development, career-development, sports performance, basketball, and sports analysis.
- Beyond gut health, the MDS study reiterates the importance of nutrition, mental health, skin care, and wellness, reinforcing the interconnectedness between various aspects of health and wellness, fitness-and-exercise, therapies-and-treatments, and career development.
