Google DeepMind Says Its New Artificial Intelligence Tool Can Predict Which Genetic Variants Are Likely to Cause Disease

Genetic engineers at the lab used the new tool to generate a catalog of 71 million possible missense variants, classifying 89% as either benign or pathogenic

Genetic engineers continue to use artificial intelligence (AI) and deep learning to develop research tools that have implications for clinical laboratories. The latest development involves Google’s DeepMind artificial intelligence lab which has created an AI tool that, they say, can predict whether a single-letter substitution in DNA—known as a missense variant (aka, missense mutation)—is likely to cause disease.

The Google engineers used their new model—dubbed AlphaMissense—to generate a catalog of 71 million possible missense variants. They were able to classify 89% as likely to be either benign or pathogenic mutations. That compares with just 0.1% that have been classified using conventional methods, according to the DeepMind engineers.

This is yet another example of how Google is investing to develop solutions for healthcare and medical care. In this case, DeepMind might find genetic sequences that are associated with disease or health conditions. In turn, these genetic sequences could eventually become biomarkers that clinical laboratories could use to help physicians make earlier, more accurate diagnoses and allow faster interventions that improve patient care.

The Google engineers published their findings in the journal Science titled, “Accurate Proteome-wide Missense Variant Effect Prediction with AlphaMissense.” They also released the catalog of predictions online for use by other researchers.

“AI tools that can accurately predict the effect of variants have the power to accelerate research across fields from molecular biology to clinical and statistical genetics,” wrote Google DeepMind engineers Jun Cheng, PhD (left), and Žiga Avsec, PhD (right), in a blog post describing the new tool. Clinical laboratories benefit from the diagnostic biomarkers generated by this type of research. (Photo copyrights: LinkedIn.)

AI’s Effect on Genetic Research

Genetic experiments to identify which mutations cause disease are both costly and time-consuming, Google DeepMind engineers Jun Cheng, PhD, and Žiga Avsec, PhD, wrote in a blog post. However, artificial intelligence sped up that process considerably.

“By using AI predictions, researchers can get a preview of results for thousands of proteins at a time, which can help to prioritize resources and accelerate more complex studies,” they noted.

Of all possible 71 million variants, approximately 6%, or four million, have already been seen in humans, they wrote, noting that the average person carries more than 9,000. Most are benign, “but others are pathogenic and can severely disrupt protein function,” causing diseases such as cystic fibrosis, sickle-cell anemia, and cancer.

“A missense variant is a single letter substitution in DNA that results in a different amino acid within a protein,” Cheng and Avsec wrote in the blog post. “If you think of DNA as a language, switching one letter can change a word and alter the meaning of a sentence altogether. In this case, a substitution changes which amino acid is translated, which can affect the function of a protein.”

In the Google DeepMind study, AlphaMissense predicted that 57% of the 71 million variants are “likely benign,” 32% are “likely pathogenic,” and 11% are “uncertain.”

The AlphaMissense model is adapted from an earlier model called AlphaFold which uses amino acid genetic sequences to predict the structure of proteins.

“AlphaMissense was fed data on DNA from humans and closely related primates to learn which missense mutations are common, and therefore probably benign, and which are rare and potentially harmful,” The Guardian reported. “At the same time, the program familiarized itself with the ‘language’ of proteins by studying millions of protein sequences and learning what a ‘healthy’ protein looks like.”

The model assigned each variant a score between 0 and 1 to rate the likelihood of pathogenicity [the potential for a pathogen to cause disease]. “The continuous score allows users to choose a threshold for classifying variants as pathogenic or benign that matches their accuracy requirements,” Avsec and Cheng wrote in their blog post.

However, they also acknowledged that it doesn’t indicate exactly how the variation causes disease.

The engineers cautioned that the predictions in the catalog are not intended for clinical use. Instead, they “should be interpreted with other sources of evidence.” However, “this work has the potential to improve the diagnosis of rare genetic disorders, and help discover new disease-causing genes,” they noted.

Genomics England Sees a Helpful Tool

BBC noted that AlphaMissense has been tested by Genomics England, which works with the UK’s National Health Service. “The new tool is really bringing a new perspective to the data,” Ellen Thomas, PhD, Genomics England’s Deputy Chief Medical Officer, told the BBC. “It will help clinical scientists make sense of genetic data so that it is useful for patients and for their clinical teams.”

AlphaMissense is “a big step forward,” Ewan Birney, PhD, Deputy Director General of the European Molecular Biology Laboratory (EMBL) told the BBC. “It will help clinical researchers prioritize where to look to find areas that could cause disease.”

Other experts, however, who spoke with MIT Technology Review were less enthusiastic.

“DeepMind is being DeepMind,” Insilico Medicine founder/CEO Alex Zhavoronkov, PhD, told the MIT publication. “Amazing on PR and good work on AI.”

Heidi Rehm, PhD, co-director of the Program in Medical and Population Genetics at the Broad Institute, suggested that the DeepMind engineers overstated the certainty of the model’s predictions. She told the publication that she was “disappointed” that they labeled the variants as benign or pathogenic.

“The models are improving, but none are perfect, and they still don’t get you to pathogenic or not,” she said.

“Typically, experts don’t declare a mutation pathogenic until they have real-world data from patients, evidence of inheritance patterns in families, and lab tests—information that’s shared through public websites of variants such as ClinVar,” the MIT article noted.

Is AlphaMissense a Biosecurity Risk?

Although DeepMind has released its catalog of variations, MIT Technology Review notes that the lab isn’t releasing the entire AI model due to what it describes as a “biosecurity risk.”

The concern is that “bad actors” could try using it on non-human species, DeepMind said. But one anonymous expert described the restrictions “as a transparent effort to stop others from quickly deploying the model for their own uses,” the MIT article noted.

And so, genetics research takes a huge step forward thanks to Google DeepMind, artificial intelligence, and deep learning. Clinical laboratories and pathologists may soon have useful new tools that help healthcare provider diagnose diseases. Time will tell. But the developments are certain worth watching.

Might Bacteria be Used to Identify Cancer Cells? Some Researchers Using Synthetic Biology and Genetic Engineering Techniques Say ‘Yes’

Cellular healthcare is an approach that goes beyond clinical laboratory testing to identify the location of specific cancer cells and aid in treatment decisions

Advances in synthetic biology and genetic engineering are leading to development of bacterial biosensors that could eventually aid pathologists and clinical laboratories in diagnosis of many types of cancers.

One recent example comes from researchers at the University of California San Diego (UCSD) who worked with colleagues in Australia to engineer bacteria that work as “capture agents” and bind to tumorous material.

The resulting “bacterial biosensors” go on a “sort of molecular manhunt” to find and capture tumor DNA with mutations in the Kirsten Rat Sarcoma virus (KRAS) gene, according to an article published by the National Cancer Institute (NCI) titled, “Could Bacteria Help Find Cancer?

The KRAS gene is associated with colorectal cancer. The researchers named their development the Cellular Assay for Targeted CRISPR-discriminated Horizontal gene transfer (CATCH). 

CATCH successfully detected cancer in the colons of mice. The researchers believe it could be used to diagnose cancers, as well as infections and other diseases, in humans as well, according to a UCSD news release.

The researchers published their proof-of-concept findings in the journal Science titled, “Engineered Bacteria Detect Tumor DNA.”

Daniel Worthley, PhD

“If bacteria can take up DNA, and cancer is defined genetically by a change in its DNA, then, theoretically, bacteria could be engineered to detect cancer,” gastroenterologist Daniel Worthley, PhD, a cancer researcher at Colonoscopy Clinic in Brisbane, Australia, told MedicalResearch.com. This research could eventually provide clinical laboratories and anatomic pathologists with new tools to use in diagnosing certain types of cancer. (Photo copyright: Colonoscopy Clinic.)

Tapping Bacteria’s Natural Competence

In their Science paper, the researchers acknowledged other synthetic biology achievements in cellular biosensors aimed at human disease. But they noted that more can be done by leveraging the “natural competence” skill of bacteria. 

“Biosensors have not yet been engineered to detect specific extracellular DNA sequences and mutations. Here, we engineered naturally competent Acinetobacter baylyi (A. baylyi) to detect donor DNA from the genomes of colorectal cancer cells, organoids, and tumors,” they wrote.

“Many bacteria can take up DNA from their environment, a skill known as natural competence,” said Rob Cooper, PhD, co-first author of the study and a scientist at US San Diego’s Synthetic Biology Institute, in the news release. A. baylyi is a type of bacteria renowned for success in doing just that, the NCI article pointed out. 

CRISPR Aids CATCH Development

Inside Precision Medicine shared these steps toward creation of the CATCH technique:

  • Researchers engineered bacteria using CRISPR.
  • This enabled them to explore “free-floating DNA sequences on a genomic level.”
  • Those sequences were compared to “known cancer DNA sequences.”
  • A. baylyi (genetically modified) was tested on its ability to detect “mutated and healthy KRAS DNA.”
  • Only bacteria that had “taken up mutated copies of KRAS … would survive treatment with a specific drug.”

“It was incredible when I saw the bacteria that had taken up the tumor DNA under the microscope. The mice with tumors grew green bacterial colonies that had acquired the ability to be grown on antibiotic plates,” said Josephine Wright, PhD, Senior Research Fellow, Gut Cancer Group, South Australian Health and Medical Research Institute (SAHMRI), in the news release. 

Detecting DNA from Cancer Cells In Vitro and in Mice

Findings in vitro and in mice include the following:

  • The engineered bacteria enabled detection of DNA with KRAS G12D from colorectal cancer cells made in the lab, NCI reported.
  • When mice were injected with colorectal cancer cells, the researchers’ technology found tumor DNA, Engadget reported.

The study adds to existing knowledge of horizontal gene transfer from bacteria to bacteria, according to UCSD.

“We observed horizontal gene transfer from the tumor to the sensor bacteria in our mouse model of colorectal cancer. This cellular assay for targeted, CRISPR-discriminated horizontal gene transfer (CATCH) enables the biodetection of specific cell-free DNA,” the authors wrote in Science.

“Colorectal cancer seemed a logical proof of concept as the colorectal lumen is full of microbes and, in the setting of cancer, full of tumor DNA,” gastroenterologist Daniel Worthley, PhD, a cancer researcher at Colonoscopy Clinic in Brisbane, Australia, told MedicalResearch.com.

Finding More Cancers and Treatment

More research is needed before CATCH is used in clinical settings. The scientists are reportedly planning on adapting CATCH to multiple bacteria that can locate other cancers and infections.

“The most exciting aspect of cellular healthcare … is not in the mere detection of disease. A laboratory can do that,” wrote Worthley in The Conversation. “But what a laboratory cannot do is pair the detection of disease (a diagnosis) with the cells actually responding to the disease [and] with appropriate treatment.

“This means biosensors can be programmed so that a disease signal—in this case, a specific sequence of cell-free DNA—could trigger a specific biological therapy, directly at the spot where the disease is detected in real time,” he added.

Clinical laboratory scientists, pathologists, and microbiologists may want to stay abreast of how the team adapts CATCH, and how bacterial biosensors in general continue to develop to aid diagnosis of diseases and improve ways to target treatment.

Data Theft at 23andMe Leaks Genetic and Personal Information for Thousands, Targets Ashkenazi Jews and Chinese

Federal class action lawsuit looms as genetics company searches for what went wrong; a reminder to clinical laboratories of the importance of protecting patient information

Several years ago, security experts warned that biotechnology and genomics company 23andMe, along with other similar genetics companies, would be attacked by hackers. Now those predictions appear to have come true, and it should be a cautionary tale for clinical laboratories. In an October 6 blog post, the genetic testing company confirmed that private information from thousands of its customers was exposed and may be being sold on the dark web.

According to Wired, “At least a million data points from 23andMe accounts appear to have been exposed on BreachForums.” BreachForums is an online forum where users can discuss internet hacking, cyberattacks, and database leaks, among other topics.

“Hackers posted an initial data sample on the platform BreachForums earlier this week, claiming that it contained one million data points exclusively about Ashkenazi Jews,” Wired reported, adding that “hundreds of thousands of users of Chinese descent” also appear to be impacted.

The leaked information included full names, dates of birth, sex, locations, photos, and both genetic and ancestry results, Bleeping Computer reported.

For its part, 23andMe acknowledges the data theft but claims “it does not see evidence that its systems have been breached,” according to Wired.

Anne Wojcicki

Anne Wojcicki (above) is the co-founder and CEO of genetics company 23andMe, which on October 24 told its customers in an email, “There was unauthorized access to one or more 23andMe accounts that were connected to you through DNA Relatives. As a result, the DNA Relatives profile information you provided in this feature was exposed to the threat actor.” Clinical laboratories must work to ensure their patient data is fully secured from similar cyber theft. (Photo copyright: TechCrunch.)

23andMe Claims Data Leak Not a Security Incident

The data leaked has been confirmed by 23andMe to be legitimate. “Threat actors used exposed credentials from other breaches [of other company’s security] to access 23andMe accounts and steal the sensitive data. Certain 23andMe customer profile information was compiled through access to individual 23andMe.com accounts,” a 23andMe spokesperson told Bleeping Computer.

However, according to the company, the leak does not appear to be a data security incident within the 23andMe systems. “The preliminary results of this investigation suggest that the login credentials used in these access attempts may have been gathered by a threat actor from data leaked during incidents involving other online platforms where users have recycled login credentials,” the spokesperson added.

What the genetics company has determined is that compromised accounts were from users choosing the DNA Relative feature on their website as a means to find and connect to individuals related to them. Additionally, “the number of accounts sold by the cybercriminal does not reflect the number of 23andMe accounts breached using exposed credentials,” Bleeping Computer noted.

Price of Private Information

Following the 23andMe data leak, the private genetic information was quickly available online … for a price.

“On October 4, the threat actor offered to sell data profiles in bulk for $1-$10 per 23andMe account, depending on how many were purchased,” Bleeping Computer reported.

Stolen medical records are becoming hotter than credit card information, the experts say. “Stolen records sell for as much as $1,000 each,” according to credit rating agency Experian, Bleeping Computer noted.

In its 2018 Global Security Report, “cybersecurity firm Trustwave pegged the black-market value of medical records at $250 each. Credit card numbers, on the other hand, sell for around $5 each on the dark web … while Social Security numbers can be purchased for as little as $1 each,” Fierce Healthcare reported.

Clinical laboratory managers and pathologists should take note of the value that the dark web places on the medical records of a patient, compared to the credit card numbers of the same individual. From this perspective, hacking a medical laboratory to steal patient health data can be much more lucrative than hacking the credit card data from a retailer.

Inevitable Federal Lawsuit

Regardless of what security measures the 23andMe site boasts, the breach quickly brought a proposed federal class action suit filed on October 9 in the US District Court for the Northern District of California. The suit, “filed by plaintiffs repressing all persons who had personal data exposed,” claims that information from Mark Zuckerberg, Elon Musk, and Sergey Brin were among the leak, Bloomberg Law reported.

“Victims of the breach are now at increased risk of fraud and identity theft, and have suffered damages in the form of invasion of privacy, lost time and out-of-pocket expenses incurred responding to the breach, diminished value of their personal information, and lost benefit of the bargain with 23andMe,” according to court documents.

“The lawsuit brings claims of negligence, breach of implied contract, invasion of privacy/intrusion upon seclusion, unjust enrichment, and declaratory judgment,” Bloomberg Law noted. Additionally, the claim states that 23andMe “failed to provide prompt and adequate notice of the incident.”

Plaintiffs are “seeking actual damages, compensatory damages, statutory damages, punitive damages, lifetime credit-monitoring services, restitution, disgorgement, injunctive relief, attorneys’ fees and costs, and pre-and post-judgment interest,” Bloomberg Law reported.

Preventing Future Data Leaks

Years of experts warning genetics companies like 23andMe that they need more strict data security have proven to be true. “This incident really highlights the risks associated with DNA databases,” Brett Callow, a threat analyst at data security firm Emsisoft, told Wired. “The fact that accounts had reportedly opted into the ‘DNA Relatives’ feature is particularly concerning as it could potentially result in extremely sensitive information becoming public.”

“Callow notes that the situation raises broader questions about keeping sensitive genetic information safe and the risks of making it available in services that are designed like social networks to facilitate sharing. With such platforms come all of the data privacy and security issues that have plagued traditional social networks, including issues related to data centralization and scraping,” Wired noted.

Clinical laboratory databases are full of protected health information (PHI). Wise lab managers will work to ensure that their medical lab’s patient data is secure from today’s cyberthreats.

Microbiome Firm Raises $86.5 Million and Inks Deal to Sell Consumer Test Kits in 200 CVS Pharmacies

Studying gut bacteria continues to intrigue investors, but can the results produce viable diagnostic data for healthcare providers?

Even as microbiologists and clinical pathologists closely watch research into the human microbiome and anticipate study findings that could lead to new medical laboratory tests based on microbiome testing, there are entrepreneurs ready to tout the benefits of microbiome testing to consumers. That’s the impetus behind an announced deal between a microbiome testing company and a national pharmacy chain.

That deal involves health startup Viome Life Sciences, which recently closed a $86.5 million Series C funding round to support research and development of its consumer health at-home test kits, and CVS, which will sell Viome’s Gut Intelligence Test at 200 of the pharmacy company’s retail locations nationwide, according to an August press release.

“Founded seven years ago by serial entrepreneur Naveen Jain, Viome sells at-home kits that analyze the microbial composition of stool samples and provide food recommendations, as well as supplements and probiotics. Viome says it is the first company to sell gut tests at CVS, both online and in-store. The tests will sell for $179,” GeekWire reported.

Investors appear to be intrigued by these types of opportunities. To date, Viome has raised a total of $175 million.

Naveen Jain

“In a world where healthcare has often been reactive, treating symptoms and targeting diseases only after they manifest, Viome is pioneering a transformative shift by harnessing the innate power of food and nutrition,” stated Naveen Jain (above), Founder and CEO of Viome, in a press release. “Our mission is not just to prolong life but to enrich it, enabling everyone to thrive in health and vitality.” But some microbiologists and clinical laboratory scientists would consider that the current state of knowledge about the human microbiome is not well-developed enough to justify offering direct-to-consumer microbiology tests that encourage consumers to purchase nutritional products.

Empowering People to Make Informed Decisions about Their Health

Established in 2016, Bellevue, Washington-based Viome produces and sells, among other tests, its Gut Intelligence at-home test kit, which analyzes the microbial composition of stool samples. This kit relies on RNA sequencing to detect bacteria and other elements present in the gut, such as yeasts and viruses.

The genetic data is then entered into an artificial intelligence (AI) algorithm to provide individuals with information regarding their personal gut health. Viome partnered with Los Alamos National Laboratory to create their AI platform. The company has collected more than 600,000 test samples to date. 

“We are the only company that looks at the gene expression and what these microbes are doing,” said Naveen Jain, Founder and CEO of Viome in the press release.

Viome uses technology combined with science to determine the optimal outcomes for each individual consumer based on his or her unique human and microbial gene expression. The data derived from the microbiome is also utilized to offer nutritional recommendations and supplement advice to test takers.

“At Viome, we’re empowering our customers with an individualized nutrition strategy, cutting through the noise of temporary trends and one-size-fits-all advice,” Jain added. “We’re on a journey to redefine aging itself, and we’re invigorated by the support of our investors and customers. Together, we’re building pathways to wellness that hold the potential to enhance the lives of billions of fellow humans across the globe.”

Manipulating Microbiome through Diet

Some scientists, however, are not sold on the idea of microbiome test kits and the data they offer to healthcare providers for treating illnesses.

“The best thing anybody can do for their microbiome is to eat a healthy diet. That’s the best way of manipulating your microbiome,” David Suskind, MD, a gastroenterologist at Seattle Children’s Hospital and Professor of Pediatrics at the University of Washington, told GeekWire.

“The kit will detect things, but we still don’t know as doctors what to do with this information for clinical practice,” gastroenterologist Elena Verdu, MD, PhD, Associate Director of the Farncombe Family Digestive Health Research Institute at McMaster University in Ontario, Canada.

Verdu, GeekWire reported, added that “there needs to be standardization of protocols and better understanding of microbiome function in health and disease.”

“Recommendations for such commercial kits would have to be based on evidence-based guidelines, which currently do not exist,” she told GeekWire.

Nevertheless, Jain remains positive about the value of microbiome testing. “The future of medicine will be delivered at home, not at the hospital. And the medicines of the future are going to come from a farm, not a pharmacy,” he told GeekWire.  

Other Viome At-home Tests

According to a paper published in the journal Therapeutic Advances in Gastroenterology  titled, “Role of the Gut Microbiota in Health and Chronic Gastrointestinal Disease: Understanding a Hidden Metabolic Organ,” the human gut contains trillions of microbes, and no two people share the exact same microbiome composition. This complex community of microbial cells influences human physiology, metabolism, nutrition and immune function, and performs a critical role in overall health.

CVS currently sells Viome’s “Gut Intelligence Health Insights Plus Personalized Nutrition Plan” on its website for $149.99. Prices may vary from online to in-store. The test is intended for individuals who want to monitor and address gut imbalances or health symptoms, such as:

  • Constipation
  • Diarrhea
  • Stomach pain
  • Bloating
  • Heartburn
  • Itchy skin
  • Trouble maintaining a healthy weight

Viome sells the Gut Intelligence Test for $179 on its own website, as well as the following health tests:

Viome also sell precision probiotics and prebiotics, as well as supplements and oral health lozenges.

Gut microbiome testing kits, such as the one from Viome, typically require the collection of a stool sample. Healthcare consumers have in the past been reluctant to perform such testing, but as more information regarding gut health is published, that reluctance may diminish.

Clinical laboratories also have a stake in the game. Dynamic direct to consumer at-home testing has the potential to generate revenue for clinical laboratories, while helping consumers who want to monitor different aspects of their health. But this would be an adjunct to the primary mission of medical laboratories to provide testing services to local physicians and their patients.

Florida Nurse Practitioner Convicted for Involvement in $200 Million Medicare Fraud Scheme Involving Clinical Laboratory Tests, Other Procedures

Federal prosecutors allege that this nurse practitioner ordered more genetic tests for Medicare beneficiaries than any other provider during 2020

Cases of Medicare fraud involving clinical laboratory testing continue to be prosecuted by the federal Department of Justice. A jury in Miami recently convicted a nurse practitioner (NP) for her role in a massive Medicare fraud scheme for millions of dollars in medically unnecessary genetic testing and durable medical equipment. She faces 75 years in prison when sentenced in December.  

In their indictment, federal prosecutors alleged that from August 2018 through June 2021 Elizabeth Mercedes Hernandez, NP, of Homestead, Florida, worked with more than eight telemedicine and marketing companies to sign “thousands of orders for medically unnecessary orthotic braces and genetic tests, resulting in fraudulent Medicare billings in excess of $200 million,” according to a US Department of Justice (DOJ) news release announcing the conviction.

“Hernandez personally pocketed approximately $1.6 million in the scheme, which she used to purchase expensive cars, jewelry, home renovations, and travel,” the press release noted.

Hernandez was indicted in April 2022 as part of a larger DOJ crackdown on healthcare fraud related to the COVID-19 outbreak.

Luis Quesada

“Throughout the pandemic, we have seen trusted medical professionals orchestrate and carry out egregious crimes against their patients all for financial gain,” said Assistant Director Luis Quesada (above) of the FBI’s Criminal Investigative Division, in a DOJ press release. Clinical laboratory managers would be wise to monitor these Medicare fraud cases. (Photo copyright: Federal Bureau of Investigation.)

Nurse Practitioner Received Kickbacks and Bribes

Federal prosecutors alleged that the scheme involved telemarketing companies that contacted Medicare beneficiaries and persuaded them to request genetic tests and orthotic braces. Hernandez, they said, then signed pre-filled orders, “attesting that she had examined or treated the patients,” according to the DOJ news release.

In many cases, Hernandez had not even spoken with the patients, prosecutors said. “She then billed Medicare as though she were conducting complex office visits with these patients, and routinely billed more than 24 hours of ‘office visits’ in a single day,” according to the news release.

In total, Hernandez submitted fraudulent claims of approximately $119 million for genetic tests, the indictment stated. “In 2020, Hernandez ordered more cancer genetic (CGx) tests for Medicare beneficiaries than any other provider in the nation, including oncologists and geneticists,” according to the news release.

The indictment noted that because CGx tests do not diagnose cancer, Medicare covers them only “in limited circumstances, such as when a beneficiary had cancer and the beneficiary’s treating physician deemed such testing necessary for the beneficiary’s treatment of that cancer. Medicare did not cover CGx testing for beneficiaries who did not have cancer or lacked symptoms of cancer.”

In exchange for signing the orders, Hernandez received kickbacks and bribes from companies that claimed to be in the telemedicine business, the indictment stated.

“These healthcare fraud abuses erode the integrity and trust patients have with those in the healthcare industry … the FBI, working in coordination with our law enforcement partners, will continue to investigate and pursue those who exploit the integrity of the healthcare industry for profit,” said Assistant Director Luis Quesada of the Federal Bureau of Investigation’s Criminal Investigative Division, in the DOJ press release.

Conspirators Took Advantage of COVID-19 Pandemic

Prosecutors alleged that as part of the scheme, she and her co-conspirators took advantage of temporary amendments to rules involving telehealth services—changes that were enacted by Medicare in response to the COVID-19 pandemic.

The indictment noted that prior to the pandemic, Medicare covered expenses for telehealth services only if the beneficiary “was located in a rural or health professional shortage area,” and “was in a practitioner’s office or a specified medical facility—not at a beneficiary’s home.”

But in response to the pandemic, Medicare relaxed the restrictions to allow coverage “even if the beneficiary was not located in a rural area or a health professional shortage area, and even if the telehealth services were furnished to beneficiaries in their home.”

Hernandez was convicted of:

  • One count of conspiracy to commit healthcare fraud and wire fraud.
  • Four counts of healthcare fraud.
  • Three counts of making false statements.

Medscape noted that she was acquitted of two counts of healthcare fraud. The trial lasted six days, Medscape reported.

Hernandez’s sentencing hearing is scheduled for Dec. 14.

Co-Conspirators Plead Guilty

Two other co-conspirators in the case, Leonel Palatnik and Michael Stein, had previously pleaded guilty and received sentences, the Miami Herald reported.

Palatnik was co-owner of Panda Conservation Group LLC, which operated two genetic testing laboratories in Florida. Prosecutors said that Palatnik paid kickbacks to Stein, owner of 1523 Holdings LLC, “in exchange for his work arranging for telemedicine providers to authorize genetic testing orders for Panda’s laboratories,” according to a DOJ press release. The kickbacks were disguised as payments for information technology (IT) and consulting services.

“1523 Holdings then exploited temporary amendments to telehealth restrictions enacted during the pandemic by offering telehealth providers access to Medicare beneficiaries for whom they could bill consultations,” the press release states. “In exchange, these providers agreed to refer beneficiaries to Panda’s laboratories for expensive and medically unnecessary cancer and cardiovascular genetic testing.”

Palatnik pleaded guilty to his role in the kickback scheme in August 2021 and was sentenced to 82 months in prison, a DOJ press release states.

Stein pleaded guilty in April and was sentenced to five years in prison, the Miami Herald reported. He was also ordered to pay $63.3 million in restitution.

These federal cases involving clinical laboratory genetic testing and other tests and medical equipment indicate a commitment on the DOJ’s part to continue cracking down on healthcare fraud.

Rise in Cancer Rates among Young People Contributes to New Phenomenon of ‘Turbo Cancers’ as a Cause for Concern

Clinical laboratories and pathologists should expect to receive increase referrals from oncologists with younger patients

More people are getting serious cases of cancer at younger and younger ages. So much so that some anatomic pathologists and epidemiologists are using the term “Turbo Cancers” to describe “the recent emergence of aggressive cancers that grow very quickly,” Vigilant News reported. 

Cancer continues to be the second leading cause of death in the United States and current trends of the disease appearing in younger populations are causing alarm among medical professionals and scientists.

“Because these cancers have been occurring in people who are too young to get them, basically, compared to the normal way it works, they’ve been designated as turbo cancers,” Harvey Risch, MD, PhD, Professor Emeritus of Epidemiology in the Department of Epidemiology and Public Health at the Yale School of Public Health and Yale School of Medicine, in an interview with Epoch TV’s American Thought Leaders.

It’s anatomic pathologists who receive the biopsies and analyze them to diagnose the cancer. Thus, they are on the front lines of seeing an increased number of biopsies for younger patients showing up with the types of cancers that normally take many years to grow large enough to be discovered by imaging and lumps leading to biopsy and diagnosis. It’s a medical mystery that may have long term effects on younger populations.

Harvey Risch, MD, PhD

“What clinicians have been seeing is very strange things,” said Harvey Risch, MD, PhD (above), Professor Emeritus of Epidemiology at the Yale School of Public Health and Yale School of Medicine, in an Epoch TV interview. “For example, 25-year-olds with colon cancer, who don’t have family histories of the disease—that’s basically impossible along the known paradigm for how colon cancer works—and other long-latency cancers that they’re seeing in very young people.” Epidemiologists and anatomic pathologists are describing these conditions as “turbo cancers.” (Photo copyright: Yale University.)

Early-Onset Cancer Rates Jump Sharply

According to the federal Centers for Disease Control and Prevention (CDC), about 3.3 million Americans died in 2022, and 607,800 of those deaths were attributed to cancer. This statistic translates to approximately 18.4% of US deaths being due to cancer last year. 

An article published in the Journal of the American Medical Association titled, “Patterns in Cancer Incidence among People Younger than 50 Years in the US, 2010 to 2019,” states that the rates of cancer in people under the age of 50 has risen sharply in recent years. The study found that “the incidence rates of early-onset cancer increased from 2010 to 2019. Although breast cancer had the highest number of incident cases, gastrointestinal cancers had the fastest-growing incidence rates among all early-onset cancers.”

The largest increase in cancer diagnoses occurred in people in the 30 to 39-year-old age group. This number represents a jump of almost 20% for the years analyzed for individuals in that demographic. The researchers also found that cancer rates decreased in individuals over the age of 50.

“We are already seeing younger patients,” John Ricci, MD, Chief of Colorectal Surgery at Long Island Jewish Medical Center told US News and World Report. “We used to say 40s was extremely abnormal, but we’re definitely seeing more [cases] in the 30s than we had before.”

Breast cancer, which increased by about 8% in younger people, accounted for the most diagnoses in this age group. However, the biggest increase was 15% for gastrointestinal cancers, including colon, appendix, bile duct, and pancreatic cancer. 

Because cancer can recur or progress, researchers have concerns about what happens to young cancer patients as they grow older and what effect cancer may have on their lives.

“They are at a transitional stage in life,” Chun Chao, PhD, Research Scientist, Division of Epidemiologic Research at Kaiser Permanente, told The Hill. “If you think about it, this is the age when people are trying to establish their independence. Some people are finishing up their education. People are trying to get their first job, just start to establish their career. And people are starting new families and starting to have kids. So, at this particular age, having a cancer diagnosis can be a huge disruption to these goals.”

Sadly, young cancer survivors have a heightened risk of developing a second cancer and a variety of other health conditions, such as cardiovascular diseases and metabolic disorders.

Lifestyle a Factor in Increased Risk for Cancer

“The increase in early-onset cancers is likely associated with the increasing incidence of obesity as well as changes in environmental exposures, such as smoke and gasoline, sleep patterns, physical activity, microbiota, and transient exposure to carcinogenic compounds,” according to the JAMA study.

“Suspected risk factors may involve increasing obesity among children and young adults; also the drastic change in our diet, like increasing consumption of sugar, sweetened beverages, and high fat,” Hyuna Sung, PhD, Cancer Surveillance Researcher at the American Cancer Society, told US News and World Report. “The increase in cancers among young adults has significant implications. It is something we need to consider as a bellwether for future trends.”

“Increased efforts are required to combat the risk factors for early-onset cancer, such as obesity, heavy alcohol consumption, and smoking,” said Daniel Huang, MD, Assistant Professor of Medicine at the National University of Singapore, one of the authors of the study, in the US News and World Report interview.

Other studies also have shown a rise in so-called turbo cancers.

“Cancer as a disease takes a long time to manifest itself from when it starts. From the first cells that go haywire until they grow to be large enough to be diagnosed, or to be symptomatic, can take anywhere from two or three years for the blood cancers—like leukemias and lymphomas—to five years for lung cancer, to 20 years for bladder cancer, or 30 to 35 years for colon cancer, and so on,” Risch told the Epoch Times.

Not the Occurrence Oncologists Expect

“Some of these cancers are so aggressive that between the time that they’re first seen and when they come back for treatment after a few weeks, they’ve grown dramatically compared to what oncologists would have expected,” Risch continued. “This is just not the normal occurrence of how cancer works.”

Risch believes that damage to the immune system is the most likely cause of the rise in turbo cancers. He said the immune system usually recognizes, manages, and disables cancer cells so they cannot progress. However, when the immune system is impaired, cancer cells can multiply to the point where the immune system cannot cope with the number of bad cells.

It is a statistical fact that more people are being diagnosed with serious cases of cancer at younger and younger ages. If this trend continues, clinical laboratories and pathologists can expect to see more oncology case referrals and perform more cancer diagnostic tests for younger patients.
