Timing is Everything: ISB Study Finds Link Between Bowel Movement Frequency and Overall Health

Everybody poops, but not every day. An ISB-led research team examined the clinical, lifestyle, and multi-omic data of more than 1,400 healthy adults. How often people poop, they found, can have a large influence on one’s physiology and health.

Autoimmune Disease and Pregnancy: ISB Study Challenges Prevailing Wisdom, Unveils Nuances

An ISB-led study showed nuanced pregnancy outcomes for pregnant individuals with autoimmune disease. The findings reinforce that there isn’t a one-size-fits-all approach, and provides important new avenues for further investigation.

Lifestyle coaching improves cognitive decline in Alzheimer's disease trial.

Personalized Coaching Decreases Cognitive Decline in Early-Stage Alzheimer’s Disease Patients

Supplementing the standard of treatment for Alzheimer’s disease patients with personalized lifestyle coaching leads to less cognitive decline compared to standard of treatment alone, according to an ISB-led two-year study. The results were published in the Journal of Alzheimer’s Disease.

Building a Better BMI

ISB researchers have constructed biological body mass index (BMI) measures that offer a more accurate representation of metabolic health and are more varied, informative and actionable than the traditional, long-used BMI equation. The work was published in the journal Nature Medicine. 

Risk Factors for Severe COVID-19 in Hospitalized Adults Differ by Age

A just-published study provides new information about which hospitalized COVID-19 patients are most likely to need mechanical ventilation or to die. The ISB-led work shows that vital signs and lab results at the time of hospital admission are the most accurate predictors of disease severity, more so than comorbidities and demographics.

Predicting ‘Long COVID’ At Initial Point of COVID-19 Diagnosis

Researchers have identified several factors that can be measured at the initial point of COVID-19 diagnosis that anticipate if a patient is likely to develop long COVID. They also found that mild cases of COVID-19, not just severe cases, are associated with long COVID. Their findings were published by the journal Cell.

Maternal COVID-19 Infection Increases Risks of Preterm Birth, Low Birth Weight and Stillbirth

An ISB-led study examined the electronic health records of more than 18,000 people with SARS-CoV-2 tests during pregnancy, and found that those who contracted COVID-19 while pregnant were more likely to have poor birth outcomes including preterm birth, small for gestational age, low birth weight, and stillbirth. 

Microbiome and weight loss

Can You Lose Weight? Ask Your Microbiome

The strongest associations with weight loss success or failure – independent of BMI – are found in the genetic capacity of the gut microbiome. These new findings open the door to diagnostic tests that can identify people likely to lose weight with healthy lifestyle changes and those who might need more drastic interventions.

Metabolic Changes in Plasma and Immune Cells Associated with COVID-19 Severity, May Predict Patient Survival

Researchers from Institute for Systems Biology (ISB), Fred Hutchinson Cancer Research Center and other organizations have uncovered underlying metabolic changes that regulate how immune cells react to COVID-19. These findings are associated with COVID-19 severity and may predict patient survival. The work was published in the journal Nature Biotechnology.

COVID-19 Outcome Disparities Across Racial/Ethnic Lines

ISB researchers and their collaborators looked at the electronic health records of nearly 630,000 patients who were tested for SARS-CoV-2, and found stark disparities in COVID-19 outcomes — odds of infection, hospitalization, and in-hospital mortality — between White and non-White minority racial and ethnic groups.

The Aging Microbiome

Gut Microbiome Implicated in Healthy Aging and Longevity

The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. ISB researchers and their collaborators have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals.

Bile Acids Provide More Evidence of the Gut Microbiome’s Effect on Alzheimer’s Disease

ISB researchers and their collaborators are looking beyond the one-drug, one-solution approach that has thus far failed in Alzheimer’s disease research. Instead, they are focusing on other promising research avenues, such as the possible role of the gut microbiome in dementia.

ISB Researchers Identify Signals of Metastatic Cancer Years Prior to Diagnosis

By analyzing blood plasma samples taken at several time points, ISB researchers have identified specific proteins that persistently presented as outliers and signaled metastatic cancer well before patients were diagnosed. The findings were published in the journal Scientific Reports.

ISB Researchers Show Genetic Risk for Disease Often Reflected in Our Blood

Diseases develop gradually over years, sometimes decades, before symptoms appear, and are due to malfunctioning physiological processes brought about by our genes and environment. In research published in the journal Proceedings of the National Academy of Sciences (PNAS), ISB researchers have shown how an individual’s genetic risk for disease is often reflected in their blood.

Bacterial tug of war between prevotella and bacteroides -- gut microbiome

It’s ‘Either/Or’ for Two Common Gut Microbiome Genera, and Switching Teams Is Tougher Than Expected

There is a dichotomy between Bacteroides- and Prevotella-dominated guts — two common gut bacterial genera — and there is a significant barrier when it comes to transitioning from one to the other.

Mysteries of Cell Fate Unlocked with New Measurement and Modeling Techniques 

In the cellular process of differentiation, information about the concentrations of an important class of proteins residing in a cell’s nucleus has been lacking, a missing link needed for scientists to fully understand how the process works. ISB researchers have quantified this important class of proteins that play a key role in the formation of red blood cells.

How Old Are You? Your Body Might Disagree With That Answer

Researchers at ISB harnessed deep molecular and physiological information to determine an individual’s biological age, which they found was reflective of overall health compared to chronological age. The findings were published in the Journals of Gerontology: Series A.

Using Blood to Predict Gut Microbiome Diversity

Predicting the alpha diversity of an individual’s gut microbiome is possible by examining metabolites in the blood. The robust relationship between host metabolome and gut microbiome diversity opens the door for a fast, cheap and reliable blood test to identify individuals with low gut diversity.
