What Key Laboratory Leaders Will Learn at This Week’s 2023 Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management

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.”

Executive War College

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.
  • The growing trend of clinical laboratory-pharmacy relationships with David Pope, PharmD, CDE, Chief Pharmacy Officer at OmniSYS, XIFIN Pharmacy Solutions.
  • 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.

Clinical laboratories are invited to continue the conversations by joining the Executive War College Discussion Group and The Dark Report Discussion Group on LinkedIn.

Might Phlebotomy Become Fully Automated? Dutch Company Is Working to Develop World’s First Autonomous Blood-drawing Station

Should this AI-driven technology prove viable in clinical settings, it could contribute to easing the shortage of qualitied phlebotomists for medical laboratories worldwide

Could phlebotomists one day be out of a job? If European medical technology company Vitestro has its way, that could someday become a reality in European hospitals and in clinical laboratories worldwide. Headquartered in the Netherlands, the company has raised EUR 12.7 million ($14,057,947.50 US) in Series A financing to bring to market “the world’s first autonomous blood drawing device,” BioWorld Med Tech reported.

According to Vitestro’s website, the “device combines AI-based, ultrasound-guided 3D reconstruction with robotic needle insertion, ensuring accurate and secure blood collection. The procedure is performed fully automatically, from tourniquet to bandage application.”

This is another example of how artificial intelligence companies are finding opportunities in staffing shortages the healthcare industry is experiencing globally. In this case, the novel technology could help address the lack of qualified phlebotomists. And clinical laboratories around the world could become the proving grounds for new AI-driven devices that end up replacing human healthcare workers.

“This financing round marks a new phase of growth for Vitestro which brings the company closer to its mission of improving the venipuncture procedure for hundreds of millions of patients per year,” said Vitestro CEO and co-founder Toon Overbeeke (above), in a press release. “We look forward to growing the business and transforming patient care with Sonder Capital, leveraging their expertise in successfully commercializing medical robotic technologies.” If proven viable, clinical laboratories around the world suffering from shortages of phlebotomists could benefit from AI-driven autonomous blood draw stations.

Next Evolution for Clinical Laboratories

According to the Centers for Disease Control and Prevention (CDC), there are 14 billion clinical laboratory tests ordered annually in the US and 70% of medical decisions depend on laboratory results. One of the more common clinical laboratory procedures—venous blood draws—is pivotal in clinical diagnostics, but a worldwide shortage of skilled phlebotomists is having an impact on this critical testing method. 

With the announcement of its completion of a EUR 12.7-million Series A financing round to bring the “world’s first” autonomous blood draw device to market, Vitestro seems poised to impact both the shortage and the job prospects of existing phlebotomists. This financing round was led by San Carlos, California-based Sonder Capital and included investors with experience in the clinical laboratory and medical technology industries. 

“Automating this ubiquitous procedure is the next evolution for clinical laboratories, allowing them to improve quality of care for patients while building a more sustainable operation,” stated Andy McGibbon, Managing Partner at Sonder Capital in a March press release

According to Investopedia, Series A financing refers to “an investment in a privately-held start-up company after it has shown progress in building its business model and demonstrates the potential to grow and generate revenue. It often refers to the first round of venture money a firm raises after seed and angel investors.”

Vitestro says it will utilize the capital from this financing round to accelerate production development, prepare market authorization in the European Union, and initiate production. 

Vitestro's autonomous blood drawing machine

Vitestro’s autonomous blood drawing device prototype (above) has been tested on more than 1,000 volunteers and patients. Vitestro plans to continue its studies on the device this year and anticipates entering the European market with the device sometime in 2024. Development of this technology is something that phlebotomists and clinical laboratory managers will want to track. (Photo copyright: Vitestro.)

Coming to a Clinical Laboratory Near You

“Medical robotics will make optimal outcomes available to everyone. I strongly believe Vitestro will set the world standard in autonomous blood drawing,” said Fred Moll, MD, Managing Partner of Sonder Capital in the press release. Moll, who has been heralded as the “father of robotic surgery,” was also appointed as a non-executive board member of Vitestro. Moll co-founded Intuitive Surgical, Inc., Hansen Medical, Restoration Robotics, and Auris Health (acquired by Ethicon, a Johnson and Johnson company).

On April 12, Vitestro announced that leading Dutch clinical laboratory OLVG Lab will be the first healthcare provider to begin using their blood-drawing device. A number of hospitals, clinical laboratories, and blood drawing departments are preparing to use the device and OLVG Lab plans to have the system fully operational by late next year, according to a press release. OLVG lab provides laboratory services to hospitals, clinics, and care providers in the greater Amsterdam area. 

“Robotization has become an important topic in diagnostics. Vitestro’s technology will improve the standardization and optimization of the sampling procedure. And it helps solve staff shortages in our blood drawing department,” said Anja Leyte, director of OLVG Lab, in the press release. “But more importantly, the patients are also very positive. Our staff are really enthusiastic as well and can’t wait to start using this breakthrough technology in our healthcare.”

Vitestro’s device is still in the testing phase but could prove to be very beneficial to clinical laboratories and help alleviate the shortage of trained phlebotomists. An automated blood draw machine might also improve the consistency of the blood draw experience for both patients and healthcare professionals.

Federal Prosecutors Seek $878 Million Restitution from Former Theranos Founder/CEO Elizabeth Holmes

New lawsuit contends that the promissory notes Holmes allegedly issued on behalf of defunct clinical laboratory company Theranos are now overdue

Just weeks before Elizabeth Holmes is scheduled to begin her prison term for conviction in the federal investor fraud case related to now-defunct clinical laboratory company Theranos, the long-running legal saga of the former company founder/CEO continues to bring new twists.

This time, news emerged via a lawsuit that Holmes allegedly owes $25 million to Theranos creditors. CNBC obtained a copy of the suit and detailed its contents in a March 17 case update.

Theranos ABC, a company set up on behalf of the creditors, alleged in the lawsuit that “Holmes has not made any payments on account of any of the promissory notes,” CNBC reported. The suit was filed in Superior Court of California Count of Santa Clara.

Holmes lives with Evans and the couple’s two children in the area near San Jose, California. Holmes gave birth to her second baby in February, according to People. In January, Holmes was convicted on three counts of wire fraud and one count of conspiracy. In addition to restitution, Holmes has been ordered to spend up to 11 years and three months in prison. (Photo copyright: Axios.)

Holmes Allegedly Issued Three Promissory Notes

The complaint stated that Holmes allegedly executed the following three promissory notes while she was still CEO at Theranos:

  • August 2011 in the amount of $9,159,333.65.
  • December 2011 in the amount of $7,578,575.52.
  • December 2013 in the amount of $9,129,991.10.

A promissory note is a written promise to pay a party a certain sum of money with a specified due date for the repayment of principal and interest.

“Theranos ABC has demanded payment of promissory note one and promissory note two from Holmes, but Holmes has failed to pay any amounts on account of promissory note,” according to the lawsuit, CNBC reported. The first two notes are overdue, and the third note is due in December.

Elizabeth Holmes’ Prison Term Could Be Delayed

News of the lawsuit, which was filed in December 2022, came to light at a court hearing on March 17. During that hearing, Judge Edward Davila heard arguments about whether Holmes should remain free pending her appeal. She is otherwise scheduled to report to prison on April 27 to begin her sentence after being convicted in January 2022 of defrauding Theranos investors.

Dark Daily covered the ruling in “Disgraced Theranos Founder Elizabeth Holmes to Serve 11 Years, Three Months in Prison, Ending the Latest Chapter in the Story of the Failed Clinical Laboratory Company.”

Davila, who oversaw Holmes’ criminal case, is expected to issue a decision about her freedom during the appeal early this month. The judge is also weighing options for Holmes to pay restitution to her victims.

Prosecutors have asked that she pay back $878 million to Theranos’ former investors and other victims, according to court records reviewed by Dark Daily. The government has argued in court papers that Holmes continues to live a wealthy lifestyle despite her claiming she has no meaningful assets since the collapse of Theranos and her trial.

“Defendant has lived on an estate for over a year where, based upon the monthly cash flow statement defendant provided to the US Probation Office, monthly expenses exceed $13,000 per month,” according to court documents filed by prosecutors ahead of the March 17 hearing. “Defendant asserted that her partner pays the monthly bills rather than her but also listed her significant other’s salary as ‘$0.’”

Holmes’ attorneys argued that the government cannot take an “all or nothing” approach to restitution, and that payments should only be made to investors who testified during the trial, the Associated Press reported.

For Victims, Full Restitution Can Be Rare

The federal Department of Justice (DOJ) acknowledges in its overview of restitution that victims often never collect what they are owed by guilty parties.

“The chance of full recovery is very low,” the DOJ notes. “Many defendants will not have sufficient assets to repay their victims. Many defendants owe very large amounts of restitution to a large number of victims. In federal cases, restitution in the hundreds of thousands or millions of dollars is not unusual. While defendants may make partial payments toward the full restitution owed, it is rare that defendants are able to fully pay the entire restitution amount owed.”

Clinical laboratory professionals will note the irony that one of the biggest convicted fraudsters in US history is now largely attempting to avoid punishments associated with her crimes. If Judge Davila agrees to let Holmes remain free pending her appeal, she could stay out of prison for years and perhaps not have to pay restitution for that length of time as well.

The coming weeks will prove to be pivotal in the final outcome of the case.

Cedars-Sinai Researchers Determine Smartphone App Can Assess Stool Form as Well as Gastroenterologists and Better than IBS Patients

Artificial intelligence performs BSS assessments with higher sensitivity and specificity than human diagnosticians

In a recent study conducted by scientists at Cedars-Sinai Medical Center in Los Angeles, researchers evaluated a smartphone application (app) that uses artificial intelligence (AI) to assess and characterize digital images of stool samples. The app, it turns out, matched the accuracy of participating gastroenterologists and exceeded the accuracy of study patients’ self-reports of stool specimens, according to a news release.

Though smartphone apps are technically not clinical laboratory tools, anatomic pathologists and medical laboratory scientists (MLSs) may be interested to learn how health information technology (HIT), machine learning, and smartphone apps are being used to assess different aspects of individuals’ health, independent of trained healthcare professionals.

The issue that the Cedars Sinai researchers were investigating is the accuracy of patient self-reporting. Because poop can be more complicated than meets the eye, when asked to describe their bowel movements patients often find it difficult to be specific. Thus, use of a smartphone app that enables patients to accurately assess their stools in cases where watching the function of their digestive tract is relevant to their diagnoses and treatment would be a boon to precision medicine treatments of gastroenterology diseases.

The scientists published their findings in the American Journal of Gastroenterology, titled, “A Smartphone Application Using Artificial Intelligence Is Superior to Subject Self-Reporting when Assessing Stool Form.”

Mark Pimentel, MD

“This app takes out the guesswork by using AI—not patient input—to process the images (of bowel movements) taken by the smartphone,” said gastroenterologist Mark Pimentel, MD (above), Executive Director of Cedars-Sinai’s Medically Associated Science and Technology (MAST) program and principal investigator of the study, in a news release. “The mobile app produced more accurate and complete descriptions of constipation, diarrhea, and normal stools than a patient could, and was comparable to specimen evaluations by well-trained gastroenterologists in the study.” (Photo copyright: Cedars-Sinai.)

Pros and Cons of Bristol Stool Scale

In their paper, the scientists discussed the Bristol Stool Scale (BSS), a traditional diagnostic tool for identifying stool forms into seven categories. The seven types of stool are:

  • Type 1: Separate hard lumps, like nuts (difficult to pass).
  • Type 2: Sausage-shaped, but lumpy.
  • Type 3: Like a sausage, but with cracks on its surface.
  • Type 4: Like a sausage or snake, smooth and soft (average stool).
  • Type 5: Soft blobs with clear cut edges.
  • Type 6: Fluffy pieces with ragged edges, a mushy stool (diarrhea).
  • Type 7: Watery, no solid pieces, entirely liquid (diarrhea). 

In an industry guidance report on irritable bowel syndrome (IBS)and associated drugs for treatment, the US Food and Drug Administration (FDA) said the BSS is “an appropriate instrument for capturing stool consistency in IBS.”

But even with the BSS, things can get murky for patients. Inaccurate self-reporting of stool forms by people with IBS and diarrhea can make proper diagnoses difficult.

“The problem is that whenever you have a patient reporting an outcome measure, it becomes subjective rather than objective. This can impact the placebo effect,” gastroenterologist Mark Pimentel, MD, Executive Director of Cedars-Sinai’s Medically Associated Science and Technology (MAST) program and principal investigator of the study, told Healio.

Thus, according to the researchers, AI algorithms can help with diagnosis by systematically doing the assessments for the patients, News Medical reported.

30,000 Stool Images Train New App

To conduct their study, the Cedars-Sinai researchers tested an AI smartphone app developed by Dieta Health. According to Health IT Analytics, employing AI trained on 30,000 annotated stool images, the app characterizes digital images of bowel movements using five parameters:

  • BSS,
  • Consistency,
  • Edge fuzziness,
  • Fragmentation, and
  • Volume.

“The app used AI to train the software to detect the consistency of the stool in the toilet based on the five parameters of stool form, We then compared that with doctors who know what they are looking at,” Pimentel told Healio.

AI Assessments Comparable to Doctors, Better than Patients

According to Health IT Analytics, the researchers found that:

  • AI assessed the stool comparable to gastroenterologists’ assessments on BSS, consistency, fragmentation, and edge fuzziness scores.
  • AI and gastroenterologists had moderate-to-good agreement on volume.
  • AI outperformed study participant self-reports based on the BSS with 95% accuracy, compared to patients’ 89% accuracy.

Additionally, the AI outperformed humans in specificity and sensitivity as well:

  • Specificity (ability to correctly report a negative result) was 27% higher.
  • Sensitivity (ability to correctly report a positive result) was 23% higher.

“A novel smartphone application can determine BSS and other visual stool characteristics with high accuracy compared with the two expert gastroenterologists. Moreover, trained AI was superior to subject self-reporting of BSS. AI assessments could provide more objective outcome measures for stool characterization in gastroenterology,” the Cedars-Sinai researchers wrote in their paper.

“In addition to improving a physician’s ability to assess their patients’ digestive health, this app could be advantageous for clinical trials by reducing the variability of stool outcome measures,” said gastroenterologist Ali Rezaie, MD, study co-author and Medical Director of Cedars-Sinai’s GI Motility Program in the news release.

The researchers plan to seek FDA review of the mobile app.

Opportunity for Clinical Laboratories

Anatomic pathologists and clinical laboratory leaders may want to reach out to referring gastroenterologists to find out how they can help to better serve gastro patients. As the Cedars-Sinai study suggests, AI smartphone apps can perform BSS assessments as good as or better than humans and may be useful tools in the pursuit of precision medicine treatments for patient suffering from painful gastrointestinal disorders.

International Team of Scientists Develop Smart Diaper That Alerts Parents When It Is Soiled and Needs to Be Changed

Not the first smart diaper to come along, but consumers seem unready for diapers that can flag urinary tract infections and other biomarkers usually tested by clinical laboratories

Will wonders never cease? For centuries, parents had only their own senses to determine when infants needed diaper changing. Today, however, caregivers can rely on “smart diapers” to send alerts when a diaper is soiled. Crying, smelly babies may no longer be the gold standard in diaper management. But are smart diapers practical?

Scientists at Penn State University in collaboration with scientists from the Hebei University of Technology and Tianjin Tianzhong Yimai Technology Development Company in China think so.

Funded by the National Institutes of Health (NIH) and the National Science Foundation (NSF), Penn State’s new smart diaper is based on a simple pencil-on-paper design that utilizes an electrode sensor array treated with a sodium chloride solution that detects dampness when urine is present.

The sensor array is “so cheap and simple” it “could clear the way for wearable, self-powered health monitors for use not only in ‘smart diapers’ but also to predict major health concerns like cardiac arrest and pneumonia,” a Penn State new release noted.

However, clinical laboratory managers following similar developments probably know that this is not the first scientific effort to develop a smart diaper that uses some type of sensor to detect a biomarker and issue an alert to the wearer or caregivers.

For example, nine years ago, In “New ‘Smart Diaper’ Tests Baby’s Urine for Urinary Tract Infections, Dehydration, and Kidney Problems—then Alerts Baby’s Doctor,” Dark Daily reported on a digital smart diaper invented by New York startup Pixie Scientific that constantly monitors a baby’s health to detect urinary tract infections, kidney problems, or dehydration before the health issue escalates. That smart diaper also uses a smartphone app to send data to the baby’s doctor.

In this latest research effort, the scientists published their findings in the journal Nano Letters, titled, “Pencil-on-Paper Humidity Sensor Treated with NaCl Solution for Health Monitoring and Skin Characterization.”

Huanyu "Larry" Cheng, PhD

“Our team has been focused on developing devices that can capture vital information for human health,” said Huanyu “Larry” Cheng, PhD (above), the James L. Henderson, Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State in a news release. “The goal is early prediction for disease conditions and health situations, to spot problems before it is too late.” This is yet another example of how researchers are working to take more testing out of clinical laboratories and offer unique assays that can be used as wearables—whether as a diaper, a skin patch, or a smart watch. (Photo copyright: Penn State University.)

This Smart Diaper Is as Simple to Use as Paper and Pencil

The Penn State sensor array takes advantage of how paper naturally reacts to wetness and utilizes the graphite in pencil marking to interact with the water molecules and sodium chloride.

Once the water molecules are absorbed by the paper, the sodium chloride solution becomes ionized and electrons start to stream towards the graphite. This movement sets off the sensor, which is extremely sensitive to humidity. According to the study, the sensor can provide accurate readings over a wide range of humidity levels, from 5.6% to 90%.

“We wanted to develop something low-cost that people would understand how to make and use, and you can’t get more accessible than pencil and paper,” said Li Yang, PhD, a professor in the School of Artificial Intelligence at China’s Hebei University of Technology and one of the authors of the study, in the Penn State news release.

“You don’t need to have some piece of multi-million-dollar equipment for fabrication. You just need to be able to draw within the lines of a pre-drawn electrode on a treated piece of paper. It can be done simply and quickly.”

The diaper is connected to a tiny lithium battery. When the sensor recognizes an increase in humidity the battery powers transmission of the change to a smartphone via Bluetooth technology. This notification informs caregivers that it is time to change the diaper.

“That application was actually born out of personal experience,” explained Huanyu “Larry” Cheng, PhD, James L. Henderson, Jr. Memorial Associate Professor of Engineering Science and Mechanics at Penn State, one of the authors of the study and father to two young children. “There’s no easy way to know how wet is wet, and that information could be really valuable for parents. The sensor can provide data in the short-term, to alert for diaper changes, but also in the long-term, to show patterns that can inform parents about the overall health of their child.”

Do Consumers Want Smart Diapers?

Research into such wearable sensors has been gaining momentum in the scientific community as a novel way to detect and deal with several medical conditions. The Penn State team hopes that devices such as their smart diaper can be used in the future to alert caregivers about the overall health of their children and clients.

“Our team has been focused on developing devices that can capture vital information for human health,” Cheng said. “The goal is early prediction for disease conditions and health situations, to spot problems before it is too late.” 

Previous research teams have had similar smart diaper goals.

In “Researchers in Japan Have Developed a ‘Smart’ Diaper Equipped with a Self-powered Biosensor That Can Monitor Blood Glucose Levels in Adults,” we covered how a team of researchers at Tokyo University of Science (TUS) in Japan had developed a diaper that detects blood glucose levels in individuals living with diabetes, a debilitating illness.

However, these types of products have yet to gain significant popularity with consumers. Regardless, sales projections for smart diapers remain positive.

According to a MarketsandMarkets report, the smart diaper market, estimated to be $646 million (US) in 2021, is expected to surpass $1.5 billion by 2026. The demand for smart diapers, the report notes, is increasing due to:

  • Growing elderly populations,
  • Rising disposable incomes,
  • Increasing personal hygiene awareness,
  • Growing populations in emerging countries, and
  • Expanding preference for advanced technology when it comes to health.

So, it’s uncertain if consumers are now ready for a device in their baby’s diaper telling them it’s time for a change. Regardless, researchers will likely continue developing tools that combine new diagnostics with existing products to help people better understand and monitor their health and the health of their loved ones.

Meanwhile, clinical laboratory managers and pathologists can remain on the alert for future published studies and press releases announcing new wearable items containing sensors, such as smart diapers. The unanswered question is whether both consumers and healthcare professionals will consider these novel inventions useful devices in the care of young and old alike.

With New Daily Monkeypox Cases Now in Single Digits, Can We Declare the Mission Accomplished?

Coordinating at-home testing for monkeypox may provide opportunities for clinical laboratories to add value for their physician clients

Microbiologists and clinical laboratory managers who oversee medical laboratory tests for monkeypox (aka, mpox) will be interested to learn that, according to the US Centers of Disease Control (CDC), cases per day have dropped into the single digits.

The United States led the world in cases during the 2022-2023 outbreak, according to the most recent CDC statistics. As of February 15, the US has reported 30,193 cases of monkeypox with 32 deaths.

Nevertheless, January 31 was the day that the US public health emergency involving monkeypox officially expired. Data from the World Health Organization shows the number of daily monkeypox cases in most countries around the world is declining, although numbers of cases are still increasing in some South American countries.

The global monkeypox outbreak appears to have slowed considerably, but are we out of the woods?

Jonathan Mermin, MD

“There were concerns that there would be ongoing transmission and that ongoing transmission would become endemic in the United States like other STIs: gonorrhea, chlamydia, syphilis. We have not seen that occur,” Jonathan Mermin, MD (above), Director of the National Center for HIV, Viral Hepatitis, STD, and TB Prevention at the CDC, told CNN.” We are now seeing three to four cases a day in the United States, and it continues to decline. And we see the possibility of getting to zero as real.” This decline in monkeypox test corresponds with a similar decline in COVID-19 clinical laboratory testing as well. (Photo Copyright: CDC.)

Untried Vaccine and At-home Testing for Monkeypox

When the monkeypox outbreak began in May of 2022, there were concerns about the US’ level of preparedness for dealing with a second pandemic while also battling COVID-19. But monkeypox was not entirely unknown to the scientific and medical communities.

Monkeypox first appeared in 1958 amongst a colony of monkeys being kept for research. The origin of the disease is not known. According to the CDC, the first reported human case of monkeypox was in 1970. Prior to the 2022 outbreak, most cases were found in central and western African countries. Cases outside of those areas could be traced back to travel from those specific countries.

When cases of monkeypox first appeared in the US, public health officials were concerned about the availability of testing, vaccines, and treatments. As CNN reported, though there was a new vaccine available, its effectiveness against monkeypox had never been tested on humans.

That treatment, known as TPOXX (Tecovirimat), was an antiviral drug approved by the FDA in 2018 to treat smallpox in adults and children, according to an FDA factsheet. The drug was difficult to obtain, and it took until August of 2022 for the federal government to declare monkeypox a public health emergency. That allowed it to deploy emergency funds towards fighting the outbreak.

The US government eventually set up a task force to address the outbreak led by Robert Fenton Jr. from the Federal Emergency Management Agency (FEMA), and Demetre Daskalakis, MD, Director of the CDC’s Division of HIV/AIDS Prevention (DHAP) in the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP).

The demographic found to be at the highest risk of monkeypox infection were men who have sex with other men. According to MedPage Today, “Daskalakis had both pandemic experience as former senior lead on equity in COVID-19 data and engagement for the New York City Department of Health and Mental Hygiene and an ‘in’ with the LGBTQ+ community from his work in HIV prevention and his transparency about being a gay man.”

When comparing monkeypox to HIV, Daskalakis said, “This one [monkeypox], you don’t have to change behaviors for generations; it’s for a few months. Once you build your force field of immunity with vaccines, people can make their own informed decisions about their risk.”

Opportunities for Clinical Laboratories

So, how should clinical laboratories respond if there’s another monkeypox flare up?

Daskalakis advocates for home testing. “People that are going to order home tests are going to be motivated to action in other ways. And so, thinking about HIV home testing, which was the grandparent of COVID-19 home testing, this really shows us how you reach people you’re not going to reach when you have lab-based, provider-only testing … When you look at the HIV home testing data from the CDC, 26% of the people that ordered a home test had never been tested before. That is way higher than what you would expect,” he told MedPage Today.

In “Healthcare Experts Say Consumers Are Ready for Self-Test Flu Kits, but Are Physicians and Clinical Laboratories Ready to Let That Cat Out of the Bag?Dark Daily explored similar opportunities for clinical laboratories to be instrumental in increasing consumers safety by helping patients accurately collect samples, administer tests, and understand test results.

We are not out of the woods in regard to monkeypox, vigilance is still required. But with existing harm reduction measures in the most vulnerable community, at-home testing and advancements in vaccines could help us keep our numbers as low as possible.
