Although it is a non-specific procedure that does not identify specific health conditions, it could lead to new biomarkers that clinical laboratories could use for predictive healthcare
Researchers from the Mayo Clinic recently used artificial intelligence (AI) to develop a predictive computational tool that analyzes an individual’s gut microbiome to identify how a person may experience improvement or deterioration in health.
Dubbed the Gut Microbiome Wellness Index 2 (GMWI2), Mayo’s new tool does not identify the presence of specific health conditions but can detect even minor changes in overall gut health.
Built on an earlier prototype, GMWI2 “demonstrated at least 80% accuracy in differentiating healthy individuals from those with any disease,” according to a Mayo news release. “The researchers used bioinformatics and machine learning methods to analyze gut microbiome profiles in stool samples gathered from 54 published studies spanning 26 countries and six continents. This approach produced a diverse and comprehensive dataset.”
“Our tool is not intended to diagnose specific diseases but rather to serve as a proactive health indicator,” said senior study author Jaeyun Sung, PhD (above), a computational biologist at the Mayo Clinic Center for Individualized Medicine: Microbiomics Program in the news release ease. “By identifying adverse changes in gut health before serious symptoms arise, the tool could potentially inform dietary or lifestyle modifications to prevent mild issues from escalating into more severe health conditions, or prompt further diagnostic testing.” For microbiologists and clinical laboratory managers, this area of new knowledge about the human microbiome may lead to multiplex diagnostic assays.

Connecting Specific Diseases with Gut Microbiome
Gut bacteria that resides in the gastrointestinal tract consists of trillions of microbes that help regulate various bodily functions and may provide insights regarding the overall health of an individual. An imbalance in the gut microbiome is associated with an assortment of illnesses and chronic diseases, including cardiovascular issues, digestive problems, and some cancers and autoimmune diseases.
To develop GMWI2, the Mayo scientists provided the machine-learning algorithm with data on microbes found in stool samples from approximately 8,000 people collected from 54 published studies. They looked for the presence of 11 diseases, including colorectal cancer and inflammatory bowel disease (IBS). About 5,500 of the subjects had been previously diagnosed with one of the 11 diseases, and the remaining people did not have a diagnosis of the conditions.
The scientists then tested the efficacy of GMWI2 on an additional 1,140 stool samples from individuals who were diagnosed with conditions such as pancreatic cancer and Parkinson’s disease, compared with those who did not have those illnesses.
The algorithm gives subjects a score between -6 and +6. People with a higher GMWI2 score have a healthier microbiome that more closely resembles individuals who do not have certain diseases.
Likewise, a low GMWI2 score suggests the individual has a gut microbiome that is similar to those who have specific illnesses.
Highly Accurate Results
According to their study, the researchers determined that “GMWI2 achieves a cross-validation balanced accuracy of 80% in distinguishing healthy (no disease) from non-healthy (diseased) individuals and surpasses 90% accuracy for samples with higher confidence,” they wrote in Nature Communications.
Launched in 2020, the original GMWI (Gut Microbiome Wellness Index) was trained on a much smaller number of samples but still showed similar results.
The researchers tested the enhanced GMWI2 algorithm across various clinical schemes to determine if the results were similar. These scenarios included individuals who had previous fecal microbiota transplants and people who had made dietary changes or who had exposure to antibiotics. They found that their improved tool detected changes in gut health in those scenarios as well.
“By being able to answer whether a person’s gut is healthy or trending toward a diseased state, we ultimately aim to empower individuals to take proactive steps in managing their own health,” Sung said in the news release.
The Mayo Clinic team is developing the next version of their tool, which will be known as the Gut Microbiome Wellness Index 3. They plan to train it on at least 12,000 stool samples and use more sophisticated algorithms to decipher the data.
More research and studies are needed to determine the overall usefulness of Mayo’s Gut Microbiome Wellness Index and its marketability. Here is a world-class health institution disclosing a pathway/tool that analyzes the human microbiome to identify how an individual may be experiencing either an improvement in health or a deterioration in health.
The developers believe it will eventually help physicians determine how patients’ conditions are improving or worsening by comparing the patients’ microbiomes to the profiles of other healthy and unhealthy microbiomes. As this happens, it would create a new opportunity for clinical laboratories to perform the studies on the microbiomes of patients being assayed in this way by their physicians.
Results of an earlier study in which locks of Beethoven’s hair underwent genetic analysis showed the composer ‘had a predisposition for liver disease and became infected with hepatitis B’
Here is an example of modern technologies being used with “historical biospecimens” to solve long-standing mysteries or questions about the illnesses of famous historical figures. Clinical laboratory scientists at the Mayo Clinic have used modern-day chemical analysis techniques to answer a 200-year-old question: What caused Ludwig van Beethoven’s deafness and other health problems?
“Such lead levels are commonly associated with gastrointestinal and renal ailments and decreased hearing but are not considered high enough to be the sole cause of death,” the authors wrote.
Beethoven’s death at age 56 has been attributed to kidney and liver disease, CNN reported. Even if the lead concentrations were not the sole cause, they would nevertheless be regarded as lead poisoning, lead study author Nader Rifai, PhD, told CNN.
“If you walk into any emergency room in the United States with these levels, you will be admitted immediately and you will undergo chelation therapy,” he said.
“It is believed that Beethoven died from liver and kidney disease at age 56. But the process of understanding what caused his many health problems has been a much more complicated puzzle, one that even Beethoven himself hoped doctors could eventually solve,” CNN reported, adding, “The composer expressed his wish that his ailments be studied and shared so ‘as far as possible at least the world will be reconciled to me after my death.’” Mayo clinical laboratory scientists are using chemical analysis on authenticated locks of Beethoven’s hair to do just that.

Mass Spectrometry Analysis
Mayo Clinic’s metals laboratory, led by chemist Paul Jannetto, PhD, an associate professor in the Department of Laboratory Medicine and Pathology and Laboratory Director at the Mayo Clinic, performed the analysis on two authenticated locks of Beethoven’s hair, using inductively coupled plasma mass spectrometers.
The researchers found that one lock had 258 micrograms of lead/gram and the other had 380 micrograms. Normally they would expect to find less than four micrograms.
“These are the highest values in hair I’ve ever seen,” Jannetto told The New York Times. “We get samples from around the world and these values are an order of magnitude higher.”
The researchers also found that the composer’s hair had four times the normal level of mercury and 13 times the normal amount of arsenic.
Rifai and other researchers noted that Beethoven drank large amounts of plumbed wine, and at the time it was common to sweeten wine with lead acetate, CNN reported.
The composer also could have been exposed to lead in glassware. He likely absorbed high levels of arsenic and mercury by eating fish caught from the Danube River in Vienna.
David Eaton, PhD, a toxicologist, pharmacologist, and Professor Emeritus, Department of Environmental and Occupational Health Sciences at the University of Washington, told The New York Times that high levels of lead could have impaired Beethoven’s hearing through their effect on the nervous system. Additionally, he said the composer’s gastrointestinal ailments “are completely consistent with lead poisoning.”
Rifai told CNN that he’d like to study locks of hair from other 19th century Vienna residents to see how their lead levels compared with Beethoven’s.
Beethoven’s Genome and Genetic Predisposition for Liver Disease
Additional research published in May built on an earlier genomic analysis of Beethoven’s hair, which appeared in March 2023 in the journal Current Biology.
The international team included geneticists, archeologists, and immunologists who analyzed eight locks of hair attributed to the composer. They determined that five were authentic. One, known as the Stumpff Lock, appeared to be the best preserved. They used this lock to sequence Beethoven’s DNA.
“Although we could not identify a genetic explanation for Beethoven’s hearing disorder or gastrointestinal problems, we found that Beethoven had a genetic predisposition for liver disease,” the authors wrote. “Metagenomic analyses revealed furthermore that Beethoven had a hepatitis B infection during at least the months prior to his death. Together with the genetic predisposition and his broadly accepted alcohol consumption, these present plausible explanations for Beethoven’s severe liver disease, which culminated in his death.”
One surprising discovery was the likelihood of an extramarital affair on the composer’s father’s side, CNN reported. The researchers learned this in part by comparing his genetic profile with those of living relatives.
“Through the combination of DNA data and archival documents, we were able to observe a discrepancy between Ludwig van Beethoven’s legal and biological genealogy,” study coauthor Maarten Larmuseau, PhD, told CNN. Larmuseau is assistant professor, Faculty of Medicine, and head of the Laboratory of Human Genetic Genealogy at KU Leuven in Belgium.
The Mayo Clinic team used two locks authenticated in the 2023 study—the Bermann Lock and Halm-Thayer Lock—to perform their chemical analysis, CNN reported.
Beethoven’s Wishes
The earlier study noted that Beethoven wanted his health problems to be made public. In 1802, he wrote a document known as the Heiligenstadt Testament in which he asked that his physician, surgeon/ophthalmologist Johann Adam Schmidt, MD, discuss his disease after he died.
“For almost two years I have ceased to attend any social functions, just because I find it impossible to say to people: I am deaf,” Beethoven wrote at age 30, The New York Times reported. “If I had any other profession, I might be able to cope with my infirmity, but in my profession, it is a terrible handicap. And if my enemies, of whom I have a fair number, were to hear about it, what would they say?”
The authors of the Current Biology paper wrote, “Genomic sequence data from authenticated locks of Beethoven’s hair provide Beethoven studies with a novel primary source, already revealing several significant findings relating to Beethoven’s health and genealogy, including substantial heritable risk for liver disease, infection with HBV [Hepatitis B], and EPP [extra pair paternity]. This dataset additionally permits numerous future lines of scientific inquiry.
“The further development of bioinformatics methods for risk stratification and continued progress in medical genetic research will allow more precise assessments both for Beethoven’s disease risk and for the genetic inference of additional phenotypes of interest.
“This study illustrates the contribution and further potential of genomic data as a novel primary source in historical biography,” the scientists concluded.
The work of the clinical laboratory professionals at Mayo Clinic also demonstrates how advances in various diagnostic technologies can enable pathologists and lab scientists to participate in solving long-standing health questions about historical figures, especially if their hair or other types of specimens survived and can be used in the analysis.
Speedy DNA sequencing and on-the-spot digital imaging may change the future of anatomic pathology procedures during surgery
Researchers at the Center for Molecular Medicine (CMM) at UMC Utrecht, a leading international university medical center in the Netherlands, have paired artificial intelligence (AI) and machine learning with DNA sequencing to develop a diagnostic tool cancer surgeons can use during surgeries to determine in minutes—while the patient is still on the operating table—whether they have fully removed all the cancerous tissue.
The method, “involves a computer scanning segments of a tumor’s DNA and alighting on certain chemical modifications that can yield a detailed diagnosis of the type and even subtype of the brain tumor,” according to The New York Times, which added, “That diagnosis, generated during the early stages of an hours-long surgery, can help surgeons decide how aggressively to operate, … In the future, the method may also help steer doctors toward treatments tailored for a specific subtype of tumor.”
This technology has the potential to reduce the need for frozen sections, should additional development and studies confirm that it accurately and reliably shows surgeons that all cancerous cells were fully removed. Many anatomic pathologists would welcome such a development because of the time pressure and stress associated with this procedure. Pathologists know that the patient is still in surgery and the surgeons are waiting for the results of the frozen section. Most pathologists would consider fewer frozen sections—with better patient outcomes—to be an improvement in patient care.
“It’s imperative that the tumor subtype is known at the time of surgery,” Jeroen de Ridder, PhD (above), associate professor in the Center for Molecular Medicine at UMC Utrecht and one of the study leaders, told The New York Times. “What we have now uniquely enabled is to allow this very fine-grained, robust, detailed diagnosis to be performed already during the surgery. It can figure out itself what it’s looking at and make a robust classification,” he added. How this discovery affects the role of anatomic pathologists and pathology laboratories during cancer surgeries remains to be seen. (Photo copyright: UMC Utrecht.)
Rapid DNA Sequencing Impacts Brain Tumor Surgeries
The UMC Utrecht scientists employed Oxford Nanopore’s “real-time DNA sequencing technology to address the challenges posed by central nervous system (CNS) tumors, one of the most lethal type of tumor, especially among children,” according to an Oxford Nanopore news release.
The researchers called their new machine learning AI application the “Sturgeon.”
According to The New York Times, “The new method uses a faster genetic sequencing technique and applies it only to a small slice of the cellular genome, allowing it to return results before a surgeon has started operating on the edges of a tumor.”
Jeroen de Ridder, PhD, an associate professor in the Center for Molecular Medicine at UMC Utrecht, told The New York Times that Sturgeon is “powerful enough to deliver a diagnosis with sparse genetic data, akin to someone recognizing an image based on only 1% of its pixels, and from an unknown portion of the image.” Ridder is also a principal investigator at the Oncode Institute, an independent research center in the Netherlands.
The researchers tested Sturgeon during 25 live brain surgeries and compared the results to an anatomic pathologist’s standard method of microscope tissue examination. “The new approach delivered 18 correct diagnoses and failed to reach the needed confidence threshold in the other seven cases. It turned around its diagnoses in less than 90 minutes, the study reported—short enough for it to inform decisions during an operation,” The New York Times reported.
But there were issues. Where the minute samples contain healthy brain tissue, identifying an adequate number of tumor markers could become problematic. Under those conditions, surgeons can ask an anatomic pathologist to “flag the [tissue samples] with the most tumor for sequencing, said PhD candidate Marc Pagès-Gallego, a bioinformatician at UMC Utrecht and a co-author of the study,” The New York Times noted.
“Implementation itself is less straightforward than often suggested,” Sebastian Brandner, MD, a professor of neuropathology at University College London, told The Times. “Sequencing and classifying tumor cells often still required significant expertise in bioinformatics as well as workers who are able to run, troubleshoot, and repair the technology,” he added.
“Brain tumors are also the most well-suited to being classified by the chemical modifications that the new method analyzes; not all cancers can be diagnosed that way,” The Times pointed out.
Thus, the research continues. The new method is being applied to other surgical samples as well. The study authors said other facilities are utilizing the method on their own surgical tissue samples, “suggesting that it can work in other people’s hands.” But more work is needed, The Times reported.
UMC Utrecht Researchers Receive Hanarth Grant
To expand their research into the Sturgeon’s capabilities, the UMC Utrecht research team recently received funds from the Hanarth Fonds, which was founded in 2018 to “promote and enhance the use of artificial intelligence and machine learning to improve the diagnosis, treatment, and outcome of patients with cancer,” according to the organization’s website.
The researchers will investigate ways the Sturgeon AI algorithm can be used to identify tumors of the central nervous system during surgery, a UMC Utrecht news release states. These type of tumors, according to the researchers, are difficult to examine without surgery.
“This poses a challenge for neurosurgeons. They have to operate on a tumor without knowing what type of tumor it is. As a result, there is a chance that the patient will need another operation,” said de Ridder in the news release.
The Sturgeon application solves this problem. It identifies the “exact type of tumor during surgery. This allows the appropriate surgical strategy to be applied immediately,” the news release notes.
The Hanarth funds will enable Jeroen and his team to develop a variant of the Sturgeon that uses “cerebrospinal fluid instead of (part of) the tumor. This will allow the type of tumor to be determined already before surgery. The main challenge is that cerebrospinal fluid contains a mixture of tumor and normal DNA. AI models will be trained to take this into account.”
The UMC Utrecht scientists’ breakthrough is another example of how organizations and research groups are working to shorten time to answer, compared to standard anatomic pathology methods. They are combining developing technologies in ways that achieve these goals.
Research could lead to improvements in gene therapy and antiviral resistance medications while also possibly leading to a new class of clinical laboratory tests
Scientists at the University of Maryland, Baltimore County (UMBC) have discovered what may be the scariest virus of all—the Vampire Virus. It’s a term that may inspire “Walking Dead” level horror in the wake of the COVID-19 pandemic, and though virologists and microbiologists might be tempted to dismiss them as imaginary, they are all too real. Even more apropos to the Dracula saga, the UM scientists found them in a soil sample. Yikes!
Happily, this ghoulish discovery could have positive implications for gene editing, gene therapy, and the development of new antiviral medications, according to The Conversation. In turn, these positive implications may eventually trigger the need to create new diagnostic tests that clinical laboratories can offer to physicians.
The image above, taken from a University of Maryland news release, shows the satellite virus “latched onto its helper virus.” Discovery of vampire-like viruses that attach at the “neck” of other viruses may lead to important discoveries in the development of gene editing and antiviral therapies. Might clinical laboratories one day collect samples for pharmaceutical developers engaged in combating antiviral drug resistance? (Photo copyright: University of Maryland.)
Spotting a Vampire Virus
According to IFLScience, these tiny vampire viruses were first discovered by undergraduates who believed they were looking at sample contamination when analyzing sequences of bacteriophages from environmental soil samples. But upon repeating the experiment they realized it was no mistake.
In the UMBC news release, bioinformatician Ivan Erill, PhD, Professor of Biological Sciences at the University of Maryland, noted that “some viruses, called satellites, depend not only on their host organism to complete their life cycle, but also on another virus, known as a helper.
“The satellite virus needs the helper either to build its capsid, a protective shell that encloses the virus’ genetic material, or to help it replicate its DNA,” he added. “These viral relationships require the satellite and the helper to be in proximity to each other at least temporarily, but there were no known cases of a satellite actually attaching itself to a helper—until now.”
Although scientists have witnessed viruses working together before, this is the first known instance of a virus directly latching onto another virus’ capsid—rather like a vampire going for the neck.
“When I saw it, I was like, I can’t believe this,” said Tagide deCarvalho, PhD, Assistant Director of Natural and Mathematical Sciences at the University of Maryland and first author of the study, in a UM news release, “No one has ever seen a bacteriophage—or any other virus—attach to another virus.”
“Not everyone has a TEM at their disposal. [With the TEM] I’m able to follow up on some of these observations and validate them with imaging. There’s elements of discovery we can only make using the TEM,” said deCarvalho in the UMBC news release.
Using Vampire Viruses to Develop Better Gene Therapies
Spookily, the comparisons to Dracula and his parasitic brethren do not stop with their freeloading tendencies. The researchers found that some viruses without a satellite attached still showed signs of having been leeched onto before. Those viruses had the equivalent of “bite marks” showing evidence of encountering vampiric viruses in the past.
“It’s possible that a lot of the bacteriophages that people thought were contaminated were actually these satellite-helper systems,” said deCarvalho in the ISME paper.
But what does UMBC’s breakthrough mean for the greater scientific and medical community? Do we need to arm host viruses with silver crosses and necklaces of garlic? Jokes aside, this discovery could lead to further development in research of how to genetically alter viruses and deliver therapeutic elements into cells.
According to Healthline, some gene therapy or “gene editing” already involves the use of viruses. Scientists switch out the programming on a virus and trick it into healing, instead of harming the cells it infiltrates. Therefore, UMBC’s discovery could lead to new breakthroughs battling deadly viruses by using their own parasitic tricks to infiltrate other viruses.
Although groundbreaking and extremely interesting, the research is still in early stages. Any developments from this discovery aren’t likely to impact clinical laboratories any time soon. But after the past few years of battling the COVID-19 variants, this exciting discovery could help find new ways to prevent the next pandemic.
Executives and pathologists from many of the nation’s most prominent clinical laboratories are on their way to the Crescent City today to share best practices, hear case studies from innovative labs, and network
NEW ORLEANS—This afternoon, more than 900 lab CEOs, administrators, and pathologists will convene for the 28th Annual Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management conference. Three topics of great interest will center around adequate lab staffing, effective cost management, and developing new sources of lab testing revenue.
Important sessions will also address the explosion in next-generation sequencing and genetic testing, proposed FDA regulation of laboratory-developed tests (LDTs), and innovative ways that clinical laboratories and pathology groups can add value and be paid for that additional value.
All this is happening amidst important changes to healthcare and medicine in the United States. “Today, the US healthcare system is transforming itself at a steady pace,” explained Robert L. Michel, Editor-in-Chief of The Dark Report and Founder of the Executive War College. “Big multi-hospital health systems are merging with each other, and payers are slashing reimbursement for many medical lab tests, even as healthcare consumers want direct access to clinical laboratory tests and the full record of their lab test history.
“Each of these developments has major implications in how clinical laboratories serve their parent organizations, offer services directly to consumers, and negotiate with payers for fair reimbursement as in-network providers,” Michel added. “Attending the Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management equips lab leaders with the tools they’ll need to make smart decisions during these challenging times.”
Now in its 28th year, the Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management convenes April 25-26 in New Orleans. Executive War College extends to a third day with three full-day workshops: LEAN fundamentals for lab leaders, a genetic testing program track, and a digital pathology track.

Challenges and Opportunities for Clinical Laboratories
With major changes unfolding in the delivery and reimbursement of clinical services, clinical laboratory and pathology practice leaders need effective ways to respond to the evolving needs of physicians, patients, and payers. As The Dark Report has often covered, three overlapping areas are a source of tension and financial pressure for labs:
Day-to-day pressures to manage costs in the clinical laboratory or pathology practice.
The growing demand for genetic testing, accompanied by reimbursement challenges.
Evolving consumer expectations in how they receive medical care and interact with providers.
Addressing all three issues and much more, the 2023 Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management features more than 80 sessions with up to 125 lab managers, consultants, vendors, and in vitro diagnostic (IVD) experts as speakers and panelists.
Old-School Lab Rules Have Evolved into New-School Lab Rules
Tuesday’s keynote general sessions (to be reported exclusively in Wednesday’s Dark Daily ebriefing) will include four points of interest for clinical laboratory and pathology leaders who are managing change and pursuing new opportunities:
Positioning the lab to prosper by serving healthcare’s new consumers, new care models, new payment models, and more, with Michel at the podium.
How old-school lab rules have evolved into new-school lab rules and ways to transition the lab through today’s disrupters in healthcare and the clinical laboratory marketplace, with Stan Schofield, Managing Principal of the Compass Group.
Generating value by identifying risk signals in longitudinal lab data and opportunities in big data from payers, physicians, pharma, and bioresearch, with Brad Bostic, Chairman and CEO of hc1.
Wednesday’s keynote sessions (see exclusive insights in Friday’s Dark Daily ebriefing) explore:
Wednesday’s keynotes conclude with a panel discussion on delivering value to physicians, patients, and payers with lab testing services.
Clinical Labs, Payers, and Health Plans Swamped by Genetic Test Claims
Attendees of the 2023 Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management may notice a greater emphasis on whole genome sequencing and genetic testing this year.
As regular coverage and analysis in The Dark Report has pointed out, clinical laboratories, payers, and health plans face challenges with the explosion of genetic testing. Several Executive War College Master Classes will explore critical management issues of genetic and genomic testing, including laboratory benefit management programs, coverage decisions, payer relations, and best coding practices, as well as genetic test stewardship.
This year’s Executive War College also devotes a one-day intensive session on how community hospitals and local labs can set up and offer genetic tests and next-generation sequencing services. This third-day track features more than a dozen experts including:
During these sessions, attendees will be introduced to “dry labs” and “virtual CLIA labs.” These new terms differentiate the two organizations that process genetic data generated by “wet labs,” annotate it, and provide analysis and interpretation for referring physicians.
State of the Industry: Clinical Lab, Private Practice Pathology, Genetic Testing, IVD, and More
For lab consultants, executives, and directors interested in state-of-the-industry Q/A and discussions concerning commercial laboratories, private-practice pathology, and in vitro diagnostics companies, a range of breakout sessions, panels, and roundtables will cover:
Action steps to protect pathologists’ income and boost practice revenue.
Important developments in laboratory legal, regulatory, and compliance requirements.
New developments in clinical laboratory certification and accreditation, including the most common deficiencies and how to reach “assessment ready” status.
An update on the IVD industry and what’s working in today’s post-pandemic market for lab vendors and their customers.
Federal government updates on issues of concern to clinical laboratories, including PAMA, the VALID Act, and more.
Long-time attendees will notice the inclusion of “Diagnostics” into the Executive War College moniker. It’s an important addition, Michel explained for Dark Daily.
“In the recent past, ‘clinical laboratory’ and ‘anatomic pathology’ were terms that sufficiently described the profession of laboratory medicine,” he noted. “However, a subtle but significant change has occurred in recent years. The term ‘diagnostics’ has become a common description for medical testing, along with other diagnostic areas such as radiology and imaging.”
Key managers of medical laboratories, pathology groups, and in vitro diagnostics have much to gain from attending the Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management, now in its 28th year. Look for continued coverage through social media channels, at Dark Daily, and in The Dark Report.
