Survey Indicates Zoomers and Millennials Are Ready for Pharmacies to Play a Bigger Role in Their Primary Care

Demand for low cost, convenient access to doctors and drugs is driving transformation to decentralized medical care, and retail pharmacy chains see opportunity in offering primary care services

Retail pharmacies and pharmacists continue to play a growing role in healthcare as consumer demand for lower cost and convenience pushes the nation’s medical landscape away from centralized healthcare systems. Clinical laboratories have seen this in the increasing trend of consumers seeking vaccinations and home-health tests at their local drug stores.

Results of a pair of surveys dubbed “Pharmacy Next” conducted by Wolters Kluwer Health revealed that 58% of people are now willing to be treated for non-emergency healthcare conditions in non-traditional medical environments, such as retail pharmacies and clinics.

This is a finding that clinical laboratory managers and pathologists should incorporate into their labs’ strategic planning. It portends a shift in care away from the traditional primary care clinic—typically located in the campus around the community hospital—and toward retail pharmacies. Labs will want to capture the test referrals originating from the primary care clinics located in retail pharmacies.

This willingness to access medical care in non-traditional environments is especially true among people in Generation Y (Millennials) and Generation Z (Zoomers)—people born between 1981-1996 (Gen Y) and 1997-2012 (Gen Z), according to Journey Matters.

“As we saw in last year’s survey, primary care decentralization is continuing—the traditional one doctor-one patient, single point of coordination is vanishing, and this is especially evident in younger generations,” said Peter Bonis, MD, Wolters Kluwer’s Chief Medical Officer, in a press release

The online surveys of more than 2,000 US adults was weighted by age, gender, household income, and education to be representative of the entire population of the United States. 

“By preparing for this shift today, providers can work in concert across care sites to deliver the best care to patients,” said Peter Bonis, MD, Wolters Kluwer Health Chief Medical Officer, in a press release. “Likewise, newer care delivery models, like retail pharmacies and clinics, can ensure they’re ready to meet the expectations of healthcare consumers, who will increasingly be turning to them for a growing range of care needs.” Clinical laboratories may find new revenue opportunities working with the primary care clinics operating within local retail pharmacists and clinicians.

Key Findings of the Wolters Kluwer Pharmacy Next Studies

Some key insights of the surveys include:

  • Care is rapidly decentralizing with 58% stating they are likely to visit a local pharmacy for non-emergency medical care.
  • Younger generations are signaling lasting change within the industry as they are more open to non-traditional styles of care.
  • 61% of respondents envision most primary care services being provided at pharmacies, retail clinics, or pharmacy clinics within the next five years. Of the respondents, 70% of Millennials, 66% of Gen Z, 65% of Gen X, and 43% of Baby Boomers believe this transition will occur.
  • Consumers are worried about prescription costs and availability.
  • 92% of respondents said physicians and pharmacists should inform patients of generic options.
  • 59% of surveyed consumers have concerns about drug tampering and theft when it involves mail order or subscription prescription services.
  • One in three respondents believe convenience is more important than credentials in non-emergency situations.

The survey indicates that healthcare consumers across multiple generations are open to a shift in some medical services from doctors to pharmacists. However, there were some notable differences between generations.

Respondents of the Baby Boomer (55%) and Gen X (57%) generations stated they would trust a physician assistant with medication prescriptions, while only 42% of Gen Z and 47% of Millennial respondents felt the same way. 

Additionally, Boomers (57%) and Gen X (67%) said they would feel comfortable with a nurse practitioner issuing their prescriptions, while only 44% of Gen Z and 53% of Millennials said they would. 

Increased Comfort with Genetic Testing at Pharmacies

The surveys also showed that younger generations are more open to the field of pharmacogenomics, which combines pharmacology and genomics to analyze how an individual’s genetic makeup (aka, heredity) affects the efficacy and reactions to certain drugs. This is a key component of precision medicine.

Overall, 68% of individuals polled believe their individual genomic data could guide prescription decisions, with Millennials (77%) and Gen Z (74%) being the primary believers. Additionally, 88% of respondents stated they see an incentive for health insurers to cover genomic testing, and 72% said they would be open to genetic testing for personalized medical care

But pharmacists and clinicians should be aware that advancing pharmacogenomics will require addressing privacy concerns. According to the Wolters Kluwer study, 57% of Gen Z and 53% of Millennials have apprehension surrounding genetic testing due to privacy risks, with 35% of Gen X and Boomers holding that same opinion.

Healthcare Staff Shortages, Drug Cost a Concern

Survey respondents are also concerned about pharmacy staff shortages and expenditures when seeking care at a pharmacy. Half of the participants are worried they will receive the wrong medication, half worry about getting the incorrect dosage, and almost half (47%) fear receiving the wrong directions due to overburdened pharmacy employees.

More people in Gen Z (59%) and Millennials (60%) had these concerns compared to Gen X (44%) and Boomers (38%).

Sadly, a distressing 44% of those surveyed admitted to not filling a prescription due to the costs. That number jumps to a staggering 56% among individuals with no health insurance, compared to 42% for insured patients.

“From hospitals to doctors’ offices, from pharmacies to pharma and beyond, healthcare must move to more affordable and accessible primary care models, adopt innovations that help deliver more personalized care, and address persistent safety and cost concerns that consumers have about their medications,” said Bonis in the press release.

Can Pharmacies Deliver Primary Care as Well as Doctor’s Offices?

Pharmacies may be logical setting for at least some non-emergency health services. According to the Centers for Disease Control and Prevention (CDC), approximately 90% of the US population live within five miles of a pharmacy and about 72% of visits to physician’s offices involve the prescribing and monitoring of medication therapies.

“Pharmacies did step up during the COVID-19 pandemic. The proof is there that pharmacies can do it,” noted Kevin Nicholson, JD, Vice President of Policy, Regulatory, and Legal Affairs for the National Association of Chain Drug Stores (NACDS), during this year’s Healthcare Information and Management Systems Society (HIMSS) in April,  HealthLeaders reported.

“We’re not talking about complicated services. We’re talking low-acuity, very basic care,” said Anita Patel, PharmD, Vice President of Pharmacy Services Development for Walgreens, at the HIMSS conference.

Pharmacies across the country continue to add more healthcare services to their available public offerings. This trend will likely persist into the future as healthcare becomes more expensive, wait times for physician appointments increases, and medical staff shortages rise. Thus, there may be opportunities for clinical laboratories to support pharmacists and doctors working in retail settings.

Kaufman Hall Report Says Hospitals Saw Less Inpatients and Outpatients during Summer as Bad Debt and Charity Care Rose

As a result, health system-based clinical laboratories likely saw a decline in test orders as well a decrease in outreach revenue

Bad financial news continues in the hospital industry. According to an August 2023 National Hospital Flash Report from consulting firm Kaufman Hall, hospitals’ financial performance deteriorated in July, partly due to declines in inpatient and outpatient volumes and rising bad debt and charity care.

The implication from these findings is that hospital-based clinical laboratories saw a drop in test volume and any lab revenue associated with inpatient testing.

In an analysis of data from more than 1,300 hospitals, Kaufman Hall noted a dip in hospitals’ median calendar year-to-date operating margin from 1.4% in June down to 1.3% in July. The data also showed “a greater pullback in volume on the outpatient side, which may be attributed to patients choosing not to pursue elective procedures during the summer,” a Kaufman Hall news release stated.

Kaufman Hall’s National Hospital Flash Report by Erik Swanson, Senior Vice President, Data and Analytics, and Brian Pisarsky, Senior Vice President, Strategic and Financial Planning, is an analysis of actual and budget data—sampled from Syntellis Performance Solutions—which is representative of hospitals of various sizes and areas in the US.

“It’s clear that today’s challenging financial environment is here to stay, and hospital leaders must be proactive in seeking out opportunities to refine their operations and remain competitive,” said Erik Swanson, Senior Vice President, Data and Analytics, Kaufman Hall, in a news release. Clinical laboratory leaders would be wise to follow the same advice. (Photo copyright: Kaufman Hall.)

Expenses Declined, Bad Debt and Charity Care Rose

Here are other national data Kaufman Hall reported for July 2023 as compared to June 2023:

  • Adjusted discharges per calendar day dropped 7%.
  • Operating room minutes per calendar day declined 13%.
  • Emergency department visits per calendar day fell 1%.
  • Bad debt and charity care as a percentage of hospitals’ gross operating revenue was up 7%.
  • Purchased service expense per adjusted discharge was down 3%.
  • Labor expense per adjusted discharge also fell 3%.

Even though expenses slightly declined during July, patient volume decreases “pulled down” the margins, Healthcare Innovation reported, which called the report “a gloomy one.”

Also, the uptick in bad debt and charity care while volumes decreased created a “difficult situation for hospitals,” Medical Economics observed. 

Here are the report’s “key takeaways,” according to Kaufman Hall:

  • All volume indicators were down, but operating margins were still better than 2022.
  • Outpatient volume decreased more than inpatient, possibly due to patients choosing not to have elective procedures during the summer.
  • The decline in expenses was “not enough to offset revenue losses,” and inflation will continue to take its toll on labor expenses.
  • Medicaid has been “disenrolling” members in 30 states during June and July, and bad debt and charity care have increased.  

The report also called out need for improvement in providers’ discharge of patients to skilled nursing facilities. “Hospitals that prioritize care transitions to skilled nursing facilities are performing better than institutions [that] do not,” Swanson said in the news release.

“Identifying steps that can ensure a smooth transition, such as obtaining pre-authorizations and planning discharge early, will help organizations reduce expenses and improve patients’ experience,” he continued.

For Hospitals, 2023 Not as Bad as 2022

MedCity News pointed out that though July’s operating margin index decline followed four months of growth, hospitals are still way ahead of 2022 performance when median operating margins were -0.98% in July 2022.

Still, it appears hospitals are struggling to secure financial footing after 2022, an overall bad financial year for the hospital industry.

In “Tough Times Ahead for Hospitals and Their Labs,” Dark Daily’s sister publication The Dark Report referenced a Fall 2022 Current State of Hospital Finances Report, prepared by Kaufman Hall for the American Hospital Association. The report noted that “under an optimistic scenario, hospitals would lose $53 billion in revenue [in 2022]. The loss would primarily come from a $27 billion decline in outpatient revenue and $17 billion for inpatient as well as $9 billion in emergency department revenue.”

More recently, a 2023 Becker’s Hospital CFO Report compiled a list of 81 hospitals that had cut jobs since the start of the year in response to “financial and operational challenges.”

Included was Tufts Medicine in Burlington, Massachusetts. In August, the hospital “eliminated hundreds of jobs” in an outsourcing of lab outreach services to Labcorp. The Becker’s report noted that “[Tufts] said it will work with Labcorp to have the majority of affected employees transition to a similar position with Labcorp.”

Tips for Clinical Lab Financial Viability

Medical laboratory leaders need to help ensure financial health of their labs as well as quality and efficiency of services. Advice from Kaufman Hall may be applicable.

The report writers advised providers to secure payer authorizations before a “patient comes in the door.” For clinical labs, this is comparable to the need to secure insurance company authorizations for expensive genetic tests before samples are taken and tests performed.

Another tip from Kaufman Hall is to “collect and use data to inform process improvement” and “make change.”  Along those lines, medical laboratories could leverage patient data to guide launch of new services, entry to markets, workflow improvement, and costs reduction.

BioReference Laboratories’ Unique Journey during the COVID-19 Pandemic Described in ‘Swab,’ a New Book by former BRLI CEO Jon Cohen, MD

Certainly every clinical laboratory in the United States has a unique story about dealing with the challenges of the SARS-CoV-2 outbreak, but only BioReference did testing for multiple professional sports leagues and the cruise ship industry

Few would challenge the assertion that the nation’s clinical laboratories (along with public health officials) were caught flat-footed when the SARS-CoV-2 coronavirus reached the United States in the winter of 2021. Even as the federal Centers for Disease Control and Prevention (CDC) and some labs rushed to develop reliable medical laboratory tests for COVID-19 in the early weeks of the outbreak, the demand for tests far outstripped supply in this country for many months.

This was the moment when the pandemic’s need meant lab testing opportunity for medical laboratories across the nation. This was particularly true for Elmwood Park, New Jersey-based BioReference Laboratories, Inc. (BRLI), a division of OPKO, Inc. BioReference found itself in the nation’s first pandemic hot zone—New York City and surrounding counties.

Not only was this lab company geographically in the center of the first overwhelming surge of COVID-19 cases, but its management team had important relationships across government and business. For that reason, its management team was pulled into the earliest planning sessions by government officials at the city, state, and federal level.

Consequently, in the earliest days of the outbreak, BioReference was one of the nation’s first labs to help organize and support drive-through COVID-19 specimen collection centers. Its management team went on to accomplish many notable firsts in the lab’s response to the pandemic. All of this is described in the recently-published book “Swab–Leadership in the Race to Provide COVID Testing to America.”

As CEO of BioReference Laboratories during the time of the COVID-19 pandemic in 2020 and 2021, physician Jon R. Cohen, MD (above), energized his clinical lab’s management team and staff to rise to a series of unique challenges, ranging from helping set up the nation’s first drive-through COVID-19 sampling sites in New York City to performing testing for professional sports leagues, such as the NBA, the NFL, and the NHL. (Photo copyright: New York Foundling, Inc.)

Harnessing the Creativity and Energy of a Clinical Lab Staff

The book’s author is Jon R. Cohen, MD, who was CEO of BioReference Laboratories throughout the course of the pandemic. Cohen is now CEO of Talkspace, a virtual behavioral health company.

“Swab” documents BioReference lab’s response to the SARS-CoV-2 pandemic and tells the tale of how the lab company harnessed the creativity of its managers and lab scientists to speedily build up daily test volumes at a time when automation, analyzers, test kits, collection supplies, and reagents were in short supply.

Clinical laboratory professionals interested in lab management will gain valuable insights from Cohen’s approach to writing “Swab.”

While describing BioReference lab’s many innovative COVID-19 testing services, Cohen also provides readers with the management lessons and insights he used to impart needed skills to the company managers, while also inspiring BioReference Lab’s staff to devote the extra effort necessary to deliver COVID-19 testing in novel ways and in unusual settings.

When New York City hospitals were overwhelmed by cases in the earliest days of the pandemic, Cohen’s personal contacts with political leaders came into play. Just a few years earlier, Cohen had run for statewide office as a Democrat. He had friendships with the New York City Mayor Bill de Blasio, with the New York State Governor Mario Cuomo, and with Senators Charles Schumer and Kirsten Gillibrand.

Cohen’s Lab Had a Seat at Government Planning Tables

As these government officials convened various task forces to address the pandemic, Cohen describes how BioReference had a seat at the table and a voice in viable ways to organize specimen collection and COVID-19 testing literally overnight and on an unprecedented scale.

The pandemic’s early days in late February, March, and April of 2020 were only the first challenges to be overcome by the management at BioReference. “Swab” describes a remarkable progression of innovative SARS-CoV-2 testing programs initiated by Cohen and his team. Each of these testing programs was tailored to the specific needs of different industries. No other clinical laboratory organization in the United States was as successful at serving this range of clients. For example:

  • For the last eight games of the National Basketball Association’s 2020 season and playoffs, BioReference created and managed the NBA’s “biosecure bubble” program at Disney World in Orlando. Over the course of 172 games, 150,000 SARS-CoV-2 tests were performed with zero-positivity.
  • The National Football League watched the NBA play in its bubble that summer. BioReference got the call and worked with NFL management to provide COVID-19 tests. For the 2020 season, in support of 268 games played across the United States, BioReference performed 1.23 million tests for 5,000 players, coaches, and staff, with an infection rate of less than 1%.
  • Along with the NBA and NFL, BioReference provided SARS-CoV-2 testing for professional soccer and hockey, the Winter X Games, and the US men’s and women’s Olympic soccer teams.
  • One of the lab company’s more complex SARS-CoV-2 testing programs involved the cruise ship industry. In 2021, BioReference established sites in 13 ports around the US and the Caribbean. The lab placed staff on as many as 24 cruise ships at one time.
  • Of course, testing for schools, colleges, universities, and employers was part of BRLI’s testing services over the course of the COVID-19 pandemic as well.

Creativity of Clinical Lab Managers and Staff

As the examples above illustrate, “Swab” will give readers a ringside seat in how BioReference Laboratories harnessed the creativity and skills of its management team and staff to address the unprecedented demands for timely, accurate COVID-19 testing from the very beginning of the pandemic through its waning months.

Cohen writes with an accessible style and provides readers with an easy-to-read narrative of his lab company’s journey through the pandemic. Each of the book’s 10 chapters ends with a “Leadership Reflection” that Cohen uses to describe the management methods he utilized to keep BRLI’s thousands of employees on task and on time, so that the end result month after month was “mission accomplished.”

In today’s digital age, the statement “this book is available at a bookstore near you” may not be applicable. What is true is that author Jon R. Cohen’s “Swab–Leadership in the Race to Provide COVID Testing to America” can be ordered at Amazon.com, Alibris.com, and other web-based booksellers.

UK Researchers Create Conductive Thread That Can Be Woven into Clothing to Monitor Key Health Biomarkers

Meet ‘PECOTEX,’ a newly-invented cotton thread with up to 10 sensors that is washable. Its developers hope it can help doctors diagnosis disease and enable patients to monitor their health conditions

Wearable biosensors continue to be an exciting area of research and product development. The latest development in wearable biosensors comes from a team of scientists led by Imperial College London. This team created a conductive cotton thread that can be woven onto T-shirts, textiles, and face masks and used to monitor key biosignatures like heart rate, respiratory rate, and ammonia levels.

Clinical laboratory managers and pathologists should also take note that this wearable technology also can be used to diagnose and track diseases and improve the monitoring of sleep, exercise, and stress, according to an Imperial College London news release.

Should this technology make it into daily use, it might be an opportunity for clinical laboratories to collect diagnostic and health-monitoring data to add to the patient’s full record of lab test results. In turn, clinical pathologists could use that data to add value when consulting with referring physicians and their patients.

The researchers published their findings in the journal Materials Today titled, “PEDOT:PSS-modified Cotton Conductive Thread for Mass Manufacturing of Textile-Based Electrical Wearable Sensors by Computerized Embroidery.”

“Our research opens up exciting possibilities for wearable sensors in everyday clothing,” said Firat Güder, PhD, Principal Investigator and Chief Engineer at Güder Research Group at Imperial College London, in a news release. “By monitoring breathing, heart rate, and gases, they can already be seamlessly integrated, and might even be able to help diagnose and monitor treatments of disease in the future.” (Photo copyright: Wikipedia.)

Ushering in New Generation of Wearable Health Sensors

The researchers dubbed their new sensor thread PECOTEX. It’s a polystyrene sulfonate-modified cotton conductive thread that can incorporate more than 10 sensors into cloth surfaces, costs a mere 15 cents/meter (slightly over 39 inches), and is machine washable.

“PECOTEX is high-performing, strong, and adaptable to different needs,” stated Firat Güder, PhD, Principal Investigator and Chief Engineer at Güder Research Group, Imperial College London, in the press release.

“It’s readily scalable, meaning we can produce large volumes inexpensively using both domestic and industrial computerized embroidery machines,” he added.

The material is less breakable and more conductive than conventional conductive threads, which allows for more layers to be embroidered on top of each other to develop more complex sensors. The embroidered sensors retain the intrinsic values of the cloth items, such as wearability, breathability, and the feel on the skin. PECOTEX is also compatible with computerized embroidery machines used in the textile industry.

The researchers embroidered the sensors into T-shirts to track heart activity, into a face mask to monitor breathing, and into other textiles to monitor gases in the body like ammonia which could help detect issues with liver and kidney function, according to the news release.

“The flexible medium of clothing means our sensors have a wide range of applications,” said Fahad Alshabouna, a PhD candidate at Imperial College’s Department of Bioengineering and lead author of the study in the news release. “They’re also relatively easy to produce which means we could scale up manufacturing and usher in a new generation of wearables in clothing.”

Uses for PECOTEX Outside of Healthcare

The team plans on exploring new applications for PECOTEX, such as energy storage, energy harvesting, and biochemical testing for personalized medicine. They are also seeking partners for commercialization of the product.

“We demonstrated applications in monitoring cardiac activity and breathing, and sensing gases,” Fahad added. “Future potential applications include diagnosing and monitoring disease and treatment, monitoring the body during exercise, sleep, and stress, and use in batteries, heaters, and anti-static clothing.”

In addition to Imperial College London, the research was funded by the Saudi Ministry of Education, the Engineering and Physical Sciences Research Council (EPSRC), Cytiva Life Sciences, the Bill and Melinda Gates Foundation, and the US Army.

Other Wearable Biometric Sensors

Dark Daily has covered the development of many wearable health sensors in past ebriefings.

In “UC San Diego Engineers Develop Microneedle Wearable Patch That Measures Glucose, Alcohol, Muscle Fatigue in Real Time,” we covered how “lab-on-the-skin” multi-tasking microneedle sensors like the one developed at the University of California San Diego’s (UCSD) Center for Wearable Sensors to track multiple biomarkers in interstitial fluid were finding their way into chronic disease monitoring and sample collecting for clinical laboratory testing.

In “Fitbit Receives FDA Approval for a Wearable Device App That Detects Atrial Fibrillation,” we reported how personal fitness technology company Fitbit had received 510(k) clearance from the US Food and Drug Administration (FDA), as well as Conformité Européenne (CE marking) in the European Union, for its Sense smartwatch electrocardiogram app that monitors wearers’ heart rhythms for atrial fibrillation (AFib).

And in “Researchers in Japan Have Developed a ‘Smart’ Diaper Equipped with a Self-powered Biosensor That Can Monitor Blood Glucose Levels in Adults,” we reported how researchers at Tokyo University of Science (TUS) had created a self-powered, glucose-testing diaper that utilizes a biofuel cell to detect the presence of urine and measure its glucose concentration.

Wearable Sensors in Personalized Healthcare

Wearable healthcare devices have enormous potential to perform monitoring for diagnostic, therapeutic, and rehabilitation purposes and support precision medicine.

Further studies and clinical trials need to occur before PECOTEX will be ready for mass consumer use. Nevertheless, it could lead to new categories of inexpensive, wearable sensors that can be integrated into everyday clothes to provide data about an individual’s health and wellbeing.

If this technology makes it to clinical use, it could provide an opportunity for clinical laboratories to collect diagnostic data for patient records and help healthcare professionals track their patients’ medical conditions.

Northwestern University Study Shares News Insights into Aging Guided by Transcriptome, Gene Length Imbalance

Findings could lead to deeper understanding of why we age, and to medical laboratory tests and treatments to slow or even reverse aging

Can humans control aging by keeping their genes long and balanced? Researchers at Northwestern University in Evanston, Illinois, believe it may be possible. They have unveiled a “previously unknown mechanism” behind aging that could lead to medical interventions to slow or even reverse aging, according to a Northwestern news release.

Should additional studies validate these early findings, this line of testing may become a new service clinical laboratories could offer to referring physicians and patients. It would expand the test menu with assays that deliver value in diagnosing the aging state of a patient, and which identify the parts of the transcriptome that are undergoing the most alterations that reduce lifespan.

It may also provide insights into how treatments and therapies could be implemented by physicians to address aging.

The Northwestern University scientists published their findings in the journal Nature Aging title, “Aging Is Associated with a Systemic Length-Associated Transcriptome Imbalance.”

“I find it very elegant that a single, relatively concise principle seems to account for nearly all of the changes in activity of genes that happen in animals as they change,” Thomas Stoeger, PhD, postdoctoral scholar in the Amaral Lab who led the study, told GEN. Clinical laboratories involved in omics research may soon have new anti-aging diagnostic tests to perform. (Photo copyright: Amaral Lab.)

Possible ‘New Instrument’ for Biological Testing

Researchers found clues to aging in the length of genes. A gene transcript length reveals “molecular-level changes” during aging: longer genes relate to longer lifespans and shorter genes suggest shorter lives, GEN summarized.

The phenomenon the researchers uncovered—which they dubbed transcriptome imbalance—was “near universal” in the tissues they analyzed (blood, muscle, bone, and organs) from both humans and animals, Northwestern said. 

According to the National Human Genome Research Institute fact sheet, a transcriptome is “a collection of all the gene readouts (aka, transcript) present in a cell” shedding light on gene activity or expression.

The Northwestern study suggests “systems-level” changes are responsible for aging—a different view than traditional biology’s approach to analyzing the effects of single genes.

“We have been primarily focusing on a small number of genes, thinking that a few genes would explain disease,” said Luis Amaral, PhD, Senior Author of the Study and Professor of Chemical and Biological Engineering at Northwestern, in the news release.

“So, maybe we were not focused on the right thing before. Now that we have this new understanding, it’s like having a new instrument. It’s like Galileo with a telescope, looking at space. Looking at gene activity through this new lens will enable us to see biological phenomena differently,” Amaral added.

In their Nature Aging paper, Amaral and his colleagues wrote, “We hypothesize that aging is associated with a phenomenon that affects the transcriptome in a subtle but global manner that goes unnoticed when focusing on the changes in expression of individual genes.

“We show that transcript length alone explains most transcriptional changes observed with aging in mice and humans,” they continued.

Researchers Turn to AI, RNA Sequencing

According to their published study, the Northwestern University scientists used large datasets, artificial intelligence (AI), and RNA (ribonucleic acid) sequencing in their analysis of tissue derived from:

  • Humans (men and women), age 30 to 49, 50 to 69, and 70 years and older. 
  • Mice, age four months to 24 months.
  • Rats, age six to 24 months.
  • Killifish, age five weeks to 39 weeks.

Scientific American reported the following study findings:

  • In tissues studied, older animals’ long transcripts were not as “abundant” as short transcripts, creating “imbalance.”
  • “Imbalance” likely prohibited the researchers’ discovery of a “specific set of genes” changing.
  • As animals aged, shorter genes “appeared to become more active” than longer genes.
  • In humans, the top 5% of genes with the shortest transcripts “included many linked to shorter life spans such as those involved in maintaining the length of telomeres.”
  • Conversely, the researchers’ review of the leading 5% of genes in humans with the longest transcripts found an association with long lives.
  • Antiaging drugs—rapamycin (aka, sirolimus) and resveratrol—were linked to an increase in long-gene transcripts.

“The changes in the activity of genes are very, very small, and these small changes involve thousands of genes. We found this change was consistent across different tissues and in different animals. We found it almost everywhere,” Thomas Stoeger, PhD, postdoctoral scholar in the Amaral Lab who led the study, told GEN.

In their paper, the Northwestern scientists noted implications for creation of healthcare interventions.

“We believe that understanding the direction of causality between other age-dependent cellular and transcriptomic changes and length-associated transcriptome imbalance could open novel research directions for antiaging interventions,” they wrote.

Other ‘Omics’ Studies

Dark Daily has previously reported on transcriptomics studies, along with research into the other “omics,” including metabolomics, proteomics, and genomics.

In “Spatial Transcriptomics Provide a New and Innovative Way to Analyze Tissue Biology, May Have Value in Surgical Pathology,” we explored how newly combined digital pathology, artificial intelligence (AI), and omics technologies are providing anatomic pathologists and medical laboratory scientists with powerful diagnostic tools.

In “Swiss Researchers Develop a Multi-omic Tumor Profiler to Inform Clinical Decision Support and Guide Precision Medicine Therapy for Cancer Patients,” we looked at how new biomarkers for cancer therapies derived from the research could usher in superior clinical laboratory diagnostics that identify a patient’s suitability for personalized drug therapies and treatments.

And in “Human Salivary Proteome Wiki Developed at University of Buffalo May Provide Biomarkers for New Diagnostic Tools and Medical Laboratory Tests,” we covered how proteins in human saliva make up its proteome and may be the key to new, precision medicine diagnostics that would give clinical pathologists new capabilities to identify disease.

Fountain of Youth

While more research is needed to validate its findings, the Northwestern study is compelling as it addresses a new area of transcriptome knowledge. This is another example of researchers cracking open human and animal genomes and gaining new insights into the processes supporting life.

For clinical laboratories and pathologists, diagnostic testing to reverse aging and guide the effectiveness of therapies may one day be possible—kind of like science’s take on the mythical Fountain of Youth.
