Cognitive Functioning Improves After Cochlear Implant

Anyone ever tell you that you should get your hearing tested?  And it’s more than you just choosing to ignore some annoying person 😉?  Then maybe it would pay for you to actually get your hearing tested and get a hearing aid if you need one.  “But I don’t want to wear a hearing aid”.  Then prepared to get dumber.  

Lots of studies support that as sensory inputs start to waiver – poor eyesight, hearing, even taste – the cognitive decline accelerates as you age.  Who wants that?  

If you need a hearing aide – you need to get one (or two, more likely) and WEAR IT!  It might just make you smarter.

Clinically meaningful improvement in older adults at risk for mild cognitive impairment

Cognitive functioning improved 12 months after cochlear implantation for older adults with severe hearing loss and poor cognition, data from a single-center study showed.

Among 21 cochlear implant candidates whose preoperative scores indicated mild cognitive impairment, overall cognitive scores improved 12 months after cochlear implant activation from a median percentile of 5 to 12 (difference of 7, 95% CI 2-12), reported Ellen Andries, MSc, of Antwerp University Hospital in Belgium, and colleagues.

Eight participants' scores improved enough to move them out of the mild cognitive impairment category (16th percentile), Andries and co-authors reported in JAMA Otolaryngology-Head & Neck Surgery.

Speech recognition in noise improved, which was tied to a rise in cognitive abilities.

The study is one of the first to examine cochlear implants among older adults with preoperative poor cognitive functioning, the researchers noted.

"Several large studies have previously demonstrated an improvement of cognitive functioning in severely hearing-impaired older adults after cochlear implantation, but few of these studies specifically analyzed participants achieving poor cognitive outcomes preoperatively," Andries told MedPage Today.

The findings suggest cochlear implantation is not contraindicated in candidates with cognitive decline and should be considered after a multidisciplinary evaluation, she noted.

"The management of modifiable risk factors for dementia, such as hearing loss, is important as there is currently no cure for dementia and its incidence is rising rapidly," Andries added. The top modifiable risk factoropens in a new tab or window for dementia prevention is hearing loss, which accounts for 8.2% of the global dementia burden, according to a recent Lancet Commission report.

The analysis included cochlear implant candidates 55 and older with poor baseline cognitive scores among participants in Antwerp University Hospital's larger prospective cohort study from April 2015 to September 2021. Median age was 72, and 62% were men. Speech processors were activated approximately 4 weeks after cochlear implantation surgery.

All participants had a preoperative total score on the Repeatable Battery for the Assessment of Neuropsychological Status for hearing-impaired patients (RBANS-H) that indicated mild cognitive impairment -- a score at least 1 standard deviation below the mean compared with age-appropriate normative data (16th percentile or lower).

The RBANS-H evaluates five cognitive subdomains: immediate memory, attention, language, visuospatial/constructional, and delayed memory. The test battery has alternate forms A and B; both were used to assess patients 1 month preoperatively and 12 months after speech processor activation.

Speech recognition in noise was measured with the Leuven Intelligibility Sentences Test. Anxiety and depression symptoms were identified using the Hospital Anxiety and Depression Scale (HADS) preoperatively and 12 months after activation.

Most participants (16 of 21) showed improvement in the RBANS-H total percentile 12 months after cochlear implant activation. The RBANS-H percentile remained stable in one participant and decreased in four.

Speech recognition in noise improved after activation (mean score 17.16 vs 5.67 on a scale where lower is better, for a difference of −11.49, 95% CI −14.26 to −8.72). Better speech recognition in noise was associated with significantly better cognitive functioning (rs −0.48).

Other variables, including years of education, sex, RBANS-H version, and depression and anxiety symptoms, were not related to changes in RBANS-H scores.

The findings support the information degradation hypothesisopens in a new tab or window as a potential explanation for the link between hearing loss and cognition, Andries and colleagues observed. "This hypothesis states that older adults with hearing loss need to rely more on cognitive resources to compensate for impaired auditory input, resulting in more mental fatigue and a higher cognitive load, which leads to a reduction of cognitive resources available for other cognitive tasks," they noted.

The study lacked a control group for ethical reasons, the researchers pointed out, and unknown factors like infection, medications, or pain could have influenced cognitive performance.

The small sample size was also a limitation, they acknowledged. "Further longitudinal research including a larger sample of cochlear implant candidates with cognitive decline is therefore recommended," they wrote.

Healthy Eating Linked to Lower Risk of Total Mortality

The headline, of course, is the hook – Health Eating Linked to Lower Risk of Mortality.  Great – eat “what you’re supposed to” and save lives.  Only, as usual, that’s really not the whole story.  So, boatloads of people (75k women, 44k men) over lots of years (up to 36 years) showed a risk reduction of between 14 and 20 percent, which would be good, EXCEPT this compares the “best” eaters against the “worst” eaters. 

Is it worth it to get crazy about your diet? That’s not really fair – the best diet is actually not only tolerable, but good.  It’s not at all a crazy diet,  but I have a different take on all of it (Surprised??).  Before we get to that, there are some other interesting things we should note.  Certain specific categories of disease have very different results – Lung disease (to me, surprisingly) is impacted the most, with a 35-46% risk reduction (that would mean if you have lung disease – PAY ATTENTION TO YOUR DIET!).  On the other hand, Stroke is unaffected, heart disease, cardiovascular disease and cancer deaths are reduced between 6 and 18%.  

What’s my take?  The food supply is screwed up, relatively depleted of nutrition and regardless of how well you adhere to the right plan, there’s more to do.  Whether that be vitamins or other supplements, exercise, stress reduction, etc – really reducing risk of disease and death requires attention and action.   For me, that means getting some data, analyzing the results and doing “stuff” to make a difference.  

Let’s chat to see if there’s something you might want to do to change your health trajectory!

Adhering to healthy eating patterns was associated with lower risk of total and cause-specific mortality, a prospective cohort study with up to 36 years of follow-up showed.

Among 75,230 women from the Nurses' Health Study and 44,085 men from the Health Professionals Follow-up Study, those who scored in the highest quintile for healthy eating patterns recommended by the Dietary Guidelines for Americans (DGAs) had a 14% to 20% lower risk of total mortality versus those in the lowest quintile, reported Frank Hu, MD, PhD, of the Harvard T.H. Chan School of Public Health in Boston, and colleagues in JAMA Internal Medicine.

The pooled multivariable-adjusted hazard ratios of total mortality with four healthy eating patterns were (P<0.001 for trend for all):

  • Healthy Eating Index 2015 (HEI-2015): HR 0.81 (95% CI 0.79-0.84)

  • Alternate Mediterranean Diet (AMED): HR 0.82 (95% CI 0.79-0.84)

  • Healthful Plant-Based Diet Index (HPDI): HR 0.86 (95% CI 0.83-0.89)

  • Alternate Healthy Eating Index (AHEI): HR 0.80 (95% CI 0.77-0.82)

This lower risk was consistent across all racial and ethnic groups.

"This is one of the largest and longest-running studies that examine the associations of dietary scores for four healthy eating patterns recommended by the DGAs with the risk of total and cause-specific mortality in large cohort studies," Hu told MedPage Today.

"Every 5 years, the U.S. Department of Agriculture (USDA) and U.S. Department of Health and Human Services (HHS) release an updated version of the Dietary Guidelines for Americans," he explained. "It is important to evaluate adherence to DGA-recommended eating patterns and health outcomes, especially mortality, so that timely updating of DGAs can be made."

Hu noted that these findings will be valuable for the 2025-2030 Dietary Guidelines Advisory Committee, which is being created by the USDA and HHS to evaluate the current evidence on different eating patterns and health outcomes.

Beyond total mortality, healthier diets were also significantly linked to lower risk of cause-specific mortality.

Across the four different dietary patterns, people in the highest quintile saw a 6% to 13% lower risk of death from cardiovascular disease versus those in the lowest quintile. Likewise, those in the highest quintile saw a 6% to 15% lower risk of death due to heart disease, a 7% to 18% lower risk of cancer-related death, and a 35% to 46% lower risk of respiratory disease-related death.

In addition, those with the highest scores on the AMED and AHEI also saw a modestly lower risk of death due to neurodegenerative disease (HR 0.94, 95% CI 0.90-0.99 and HR 0.93, 95% CI 0.87-0.99, respectively).

"Although previous studies have found an inverse association between healthy eating patterns and mortality, our study provides evidence that healthy eating patterns reduce the risk of cause-specific mortality including cardiovascular disease, cancer, respiratory, and neurodegenerative mortality," said Hu. "The findings on respiratory and neurodegenerative mortality are novel."

However, eating a healthy diet according to any of the four patterns did not appear to be protective against stroke-related deaths.

Hu said clinicians can recommend a "variety of healthy dietary patterns" to patients in order to reduce their risk for chronic diseases and premature death.

"These patterns such as the Mediterranean diet, DASH diet, vegetarian diet, or other versions of healthy diets can be adapted to meet individual health needs, food preferences, and cultural traditions," he noted. "These healthy dietary patterns typically include high amounts of plant foods such as fruits, vegetables, whole grains, nuts, and legumes, and lower amounts of refined grains, added sugars, sodium, and red and processed meats."

"It is also important to balance caloric intake with physical activity to maintain a healthy weight," he added.

Among the women included in the analysis, mean baseline age was 50.2 and 98% were white; for men, mean age was 53.3 and 91% were white. In total, 31,263 women and 22,900 men died during follow-up. The leading cause of death was cancer, followed by cardiovascular disease, heart disease, neurodegenerative disease, respiratory disease, and stroke.

Dietary data were taken from semiquantitative food frequency questionnaires including more than 130 items, which were completed every 2 to 4 years.

Researchers Looking For Long COVID Symptoms Find Only 7

Let's get something clear that I don't think people actually know - COVID is a disease of blood vessels.  As such, it hits everything, hence a constellation of symptoms that covers the universe (get the astronomy reference?).  Also, while the mainstream suggests that there are no clear diagnostic criteria for Long Haul, there is plenty of evidence supporting specific blood tests (that we do) that ties directly to the symptoms and mirrors patients' experience. When you can fix the labs, you can fix the people.  Unfortunately, it can take a while, but it can be done.  Defining the problem remains a problem broadly, but that's why we're not doing mainstream medicine - we need to deliver solutions first.  

FROM FIERCE HEALTHCARE / BY FRANK DIAMOND

The Centers for Disease Control and Prevention’s tally of 19 possible long COVID symptoms comes with the caveat that it's “not a comprehensive list.”

Yale Medicine counts 22 symptoms, while the Mayo Clinic lists 10. And Great Britain’s National Health Service (NHS) puts the number at 16.

These lists can be made even longer. For instance, the NHS has “high temperature, cough, headaches, sore throat and changes to sense of smell or taste” as one symptom. Mayo lists “difficulty thinking or concentrating, headache, sleep problems, dizziness when you stand, pins-and-needles feeling, loss of smell or taste and depression or anxiety” as one symptom.

A major obstacle to helping patients with long COVID is that currently there are no generally agreed-upon diagnostic or treatment guidelines. Narrowing down exactly what symptoms point to long COVID would be a start, and researchers at the University of Missouri (MU) think they’ve done just that by slimming the field of long COVID symptoms down to just seven: fast-beating heart, hair loss, fatigue, chest pain, shortness of breath, joint pain and obesity.

Their study in Open Forum Infectious Diseases said that “understanding the population and subgroup risks for long COVID associated with outcomes, including lingering and chronic never-before-experienced symptoms and new medical diagnoses such as those reported here, is important for clinicians and researchers so that clinical guidelines for treatments and symptom management can be more appropriately developed for the growing number of adults affected by COVID-19.”

Chi-Ren Shyu, Ph.D., the director of the MU Institute for Data Science and Informatics and the corresponding author of the study, tells Fierce Healthcare that “understanding the population and subgroup risks for long COVID associated with outcomes, including lingering and chronic never-before-experienced symptoms and new medical diagnoses such as those reported here, is important for clinicians and researchers, so that clinical guidelines for treatments and symptom management can be more appropriately developed for the growing number of adults affected by COVID-19.”

Shyu and co-authors examined data from 52,461 patients collected in electronic health records at 122 healthcare facilities across the U.S. They identified 47 possible symptoms of long COVID. They compared symptoms in three groups:

  • Individuals who had COVID-19 but didn’t have common viral problems associated with the disease such as influenza or pneumonia.

  • Individuals who didn’t have COVID-19 but did have a different viral respiratory infection.

  • Individuals who had neither COVID-19 nor one of the other infections.

“Previous work has briefly investigated the differences in outcomes between hospitalized COVID-19 and influenza patients,” the study states. “Our work provides additional information on this subject by analyzing a larger and more diverse patient cohort, including other common viral respiratory infections, and examining outcomes in patient cohorts not limited to patients hospitalized for the initial infection.”

The authors said they hope their findings will point out what symptoms clinicians should look for when trying to determine whether somebody has long COVID. “A better recognition of post COVID syndrome or long COVID will help us study the underlying reasons that cause these prolonged abnormalities and also help us develop screening protocols to be used when COVID-19 survivors are seen within the healthcare systems,” says Shyu. “Such recognition also helps in developing focused treatments and rehabilitation strategies to promote recovery.”

Adnan Qureshi, Ph.D., a professor of neurology at the MU School of Medicine and co-author of the study, notes in a press release that the “survivors still have symptoms that are at times disabling and preventing them from going back to work or the activities of their daily life. This is not because the COVID-19 infection is still active, but instead, the infection has caused long-term consequences, or sequelae, in the form of a post-COVID syndrome that could persist for months or even years. Our research was able to identify long-term sequelae that are distinctive to COVID-19 and separate the post-COVID syndrome from other post-viral syndromes.”

One symptom of long COVID that their study found bolsters the findings of previous studies that linked the condition to heart problems.

UnitedHealthcare Tried to Deny Coverage to a Chronically Ill Patient. He Fought Back, Exposing the Insurer’s Inner Workings.

Probably everyone looking at this says “yeah, right”.  I’d bet virtually everyone has a story of their own, or a friend’s where the insurance company said no for some reason that, to the general public would seem absolutely absurd – because it was!  Recently I had a patient with Long Covid who was still suffering from fatigue, brain fog (he just started treatment) who was told by his insurance company that they would no longer be paying his disability so he could limit his work to two days a week.  We had tests that showed his executive function was slowed (he needed to be able to make split-second decisions or people could literally die), and was dependent on his dominant hand whose function also tested as well below normal.  On the limited schedule he could manage to avoid the potential disasters, but they wanted him back full-time.  Appeals didn’t matter.  Ultimately he retired, so the insurance company won all around.  

I have many stories.  Once in a very long while we can win.  But it's a sad state of affairs. 

After a college student finally found a treatment that worked, the insurance giant decided it wouldn’t pay for the costly drugs. His fight to get coverage exposed the insurer’s hidden procedures for rejecting claims.

In May 2021, a nurse at UnitedHealthcare called a colleague to share some welcome news about a problem the two had been grappling with for weeks.

United provided the health insurance plan for students at Penn State University. It was a large and potentially lucrative account: lots of young, healthy students paying premiums in, not too many huge medical reimbursements going out.

But one student was costing United a lot of money. Christopher McNaughton suffered from a crippling case of ulcerative colitis — an ailment that caused him to develop severe arthritis, debilitating diarrhea, numbing fatigue and life-threatening blood clots. His medical bills were running nearly $2 million a year.

United had flagged McNaughton’s case as a “high dollar account,” and the company was reviewing whether it needed to keep paying for the expensive cocktail of drugs crafted by a Mayo Clinic specialist that had brought McNaughton’s disease under control after he’d been through years of misery.

On the 2021 phone call, which was recorded by the company, nurse Victoria Kavanaugh told her colleague that a doctor contracted by United to review the case had concluded that McNaughton’s treatment was “not medically necessary.” Her colleague, Dave Opperman, reacted to the news with a long laugh.

“I knew that was coming,” said Opperman, who heads up a United subsidiary that brokered the health insurance contract between United and Penn State. “I did too,” Kavanaugh replied.

UnitedHealthcare Employees Discuss the Denial of Chris McNaughton’s Claim

David Opperman is an insurance broker who works for UnitedHealthcare. Victoria Kavanaugh is a nurse for United. In this recorded phone call from 2021, the two express relief that a doctor has turned down Penn State student Chris McNaughton’s claim as “not medically necessary.”

Opperman then complained about McNaughton’s mother, whom he referred to as “this woman,” for “screaming and yelling” and “throwing tantrums” during calls with United.

The pair agreed that any appeal of the United doctor’s denial of the treatment would be a waste of the family’s time and money.

“We’re still gonna say no,” Opperman said.

More than 200 million Americans are covered by private health insurance. But data from state and federal regulators shows that insurers reject about 1 in 7 claims for treatment. Many people, faced with fighting insurance companies, simply give up: One study found that Americans file formal appeals on only 0.1% of claims denied by insurers under the Affordable Care Act.

Insurers have wide discretion in crafting what is covered by their policies, beyond some basic services mandated by federal and state law. They often deny claims for services that they deem not “medically necessary.”

When United refused to pay for McNaughton's treatment for that reason, his family did something unusual. They fought back with a lawsuit, which uncovered a trove of materials, including internal emails and tape-recorded exchanges among company employees. Those records offer an extraordinary behind-the-scenes look at how one of America's leading health care insurers relentlessly fought to reduce spending on care, even as its profits rose to record levels.

As United reviewed McNaughton’s treatment, he and his family were often in the dark about what was happening or their rights. Meanwhile, United employees misrepresented critical findings and ignored warnings from doctors about the risks of altering McNaughton’s drug plan.

At one point, court records show, United inaccurately reported to Penn State and the family that McNaughton’s doctor had agreed to lower the doses of his medication. Another time, a doctor paid by United concluded that denying payments for McNaughton’s treatment could put his health at risk, but the company buried his report and did not consider its findings. The insurer did, however, consider a report submitted by a company doctor who rubber-stamped the recommendation of a United nurse to reject paying for the treatment.

United declined to answer specific questions about the case, even after McNaughton signed a release provided by the insurer to allow it to discuss details of his interactions with the company. United noted that it ultimately paid for all of McNaughton’s treatments. In a written response, United spokesperson Maria Gordon Shydlo wrote that the company’s guiding concern was McNaughton’s well-being.

“Mr. McNaughton’s treatment involves medication dosages that far exceed FDA guidelines,” the statement said. “In cases like this, we review treatment plans based on current clinical guidelines to help ensure patient safety.”

But the records reviewed by ProPublica show that United had another, equally urgent goal in dealing with McNaughton. In emails, officials calculated what McNaughton was costing them to keep his crippling disease at bay and how much they would save if they forced him to undergo a cheaper treatment that had already failed him. As the family pressed the company to back down, first through Penn State and then through a lawsuit, the United officials handling the case bristled.

“This is just unbelievable,” Kavanaugh said of McNaughton’s family in one call to discuss his case. ”They’re just really pushing the envelope, and I’m surprised, like I don’t even know what to say.”

The Same Meal Every Day

Now 31, McNaughton grew up in State College, Pennsylvania, just blocks from the Penn State campus. Both of his parents are faculty members at the university.

In the winter of 2014, McNaughton was halfway through his junior year at Bard College in New York. At 6 feet, 4 inches tall, he was a guard on the basketball team and had started most of the team’s games since the start of his sophomore year. He was majoring in psychology.

When McNaughton returned to school after the winter holiday break, he started to experience frequent bouts of bloody diarrhea. After just a few days on campus, he went home to State College, where doctors diagnosed him with a severe case of ulcerative colitis.

A chronic inflammatory bowel disease that causes swelling and ulcers in the digestive tract, ulcerative colitis has no cure, and ongoing treatment is needed to alleviate symptoms and prevent serious health complications. The majority of cases produce mild to moderate symptoms. McNaughton’s case was severe.

Treatments for ulcerative colitis include steroids and special drugs known as biologics that work to reduce inflammation in the large intestine.

McNaughton, however, failed to get meaningful relief from the drugs his doctors initially prescribed. He was experiencing bloody diarrhea up to 20 times a day, with such severe stomach pain that he spent much of his day curled up on a couch. He had little appetite and lost 50 pounds. Severe anemia left him fatigued. He suffered from other conditions related to his colitis, including crippling arthritis. He was hospitalized several times to treat dangerous blood clots.

For two years, in an effort to help alleviate his symptoms, he ate the same meals every day: Rice Chex cereal and scrambled eggs for breakfast, a cup of white rice with plain chicken breast for lunch and a similar meal for dinner, occasionally swapping in tilapia.

His hometown doctors referred him to a specialist at the University of Pittsburgh, who tried unsuccessfully to bring his disease under control. That doctor ended up referring McNaughton to Dr. Edward Loftus Jr. at the Mayo Clinic in Minnesota, which has been ranked as the best gastroenterology hospital in the country every year since 1990 by U.S. News & World Report.

For his first visit with Loftus in May 2015, McNaughton and his mother, Janice Light, charted hospitals along the 900-mile drive from Pennsylvania to Minnesota in case they needed medical help along the way.

Mornings were the hardest. McNaughton often spent several hours in the bathroom at the start of the day. To prepare for his meeting with Loftus, he set his alarm for 3:30 a.m. so he could be ready for the 7:30 a.m. appointment. Even with that preparation, he had to stop twice to use a bathroom on the five-minute walk from the hotel to the clinic. When they met, Loftus looked at McNaughton and told him that he appeared incapacitated. It was, he told the student, as if McNaughton were chained to the bathroom, with no outside life. He had not been able to return to school and spent most days indoors, managing his symptoms as best he could.

McNaughton had tried a number of medications by this point, none of which worked. This pattern would repeat itself during the first couple of years that Loftus treated him.

In addition to trying to find a treatment that would bring McNaughton’s colitis into remission, Loftus wanted to wean him off the steroid prednisone, which he had been taking since his initial diagnosis in 2014. The drug is commonly prescribed to colitis patients to control inflammation, but prolonged use can lead to severe side effects including cataracts, osteoporosis, increased risk of infection and fatigue. McNaughton also experienced “moon face,” a side effect caused by the shifting of fat deposits that results in the face becoming puffy and rounder.

In 2018, Loftus and McNaughton decided to try an unusual regimen. Many patients with inflammatory bowel diseases like colitis take a single biologic drug as treatment. Whereas traditional drugs are chemically synthesized, biologics are manufactured in living systems, such as plant or animal cells. A year’s supply of an individual biologic drug can cost up to $500,000. They are often given through infusions in a medical facility, which adds to the cost.

McNaughton had tried individual biologics, and then two in combination, without much success. He and Loftus then agreed to try two biologic drugs together at doses well above those recommended by the U.S. Food and Drug Administration. Prescribing drugs for purposes other than what they are approved for or at higher doses than those approved by the FDA is a common practice in medicine referred to as off-label prescribing. The federal Agency for Healthcare Research and Quality estimates 1 in 5 prescriptions written today are for off-label uses.

There are drawbacks to the practice. Since some uses and doses of particular drugs have not been extensively studied, the risks and efficacy of using them off-label are not well known. Also, some drug manufacturers have improperly pushed off-label usage of their products to boost sales despite little or no evidence to support their use in those situations. Like many leading experts and researchers in his field, Loftus has been paid to do consulting related to the biologic drugs taken by McNaughton. The payments related to those drugs have ranged from a total of $1,440 in 2020 to $51,235 in 2018. Loftus said much of his work with pharmaceutical companies was related to conducting clinical trials on new drugs.

In cases of off-label prescribing, patients are depending upon their doctor’s expertise and experience with the drug.“In this case, I was comfortable that the potential benefits to Chris outweighed the risks,” Loftus said.

There was evidence that the treatment plan for McNaughton might work, including studies that had found dual biologic therapy to be efficacious and safe. The two drugs he takes, Entyvio and Remicade, have the same purpose — to reduce inflammation in the large intestine — but each works differently in the body. Remicade, marketed by Janssen Biotech, targets a protein that causes inflammation. Entyvio, made by Takeda Pharmaceuticals, works by preventing an excess of white blood cells from entering into the gastrointestinal tract.

As for any suggestion by United doctors that his treatment plan for McNaughton was out of bounds or dangerous, Loftus said “my treatment of Chris was not clinically inappropriate — as was shown by Chris’ positive outcome.”

The unusual high-dose combination of two biologic drugs produced a remarkable change in McNaughton. He no longer had blood in his stool, and his trips to the bathroom were cut from 20 times a day to three or four. He was able to eat different foods and put on weight. He had more energy. He tapered off prednisone.

“If you told me in 2015 that I would be living like this, I would have asked where do I sign up,” McNaughton said of the change he experienced with the new drug regimen.

When he first started the new treatment, McNaughton was covered under his family’s plan, and all his bills were paid. McNaughton enrolled at the university in 2020. Before switching to United’s plan for students, McNaughton and his parents consulted with a health advocacy service offered to faculty members. A benefits specialist assured them the drugs taken by McNaughton would be covered by United.

McNaughton joined the student plan in July 2020, and his infusions that month and the following month were paid for by United. In September, the insurer indicated payment on his claims was “pending,” something it did for his other claims that came in during the rest of the year.

McNaughton and his family were worried. They called United to make sure there wasn’t a problem; the insurer told them, they said, that it only needed to check his medical records. When the family called again, United told them it had the documentation needed, they said. United, in a court filing last year, said it received two calls from the family and each time indicated that all of the necessary medical records had not yet been received.

In January 2021, McNaughton received a new explanation of benefits for the prior months. All of the claims for his care, beginning in September, were no longer “pending.” They were stamped “DENIED.” The total outstanding bill for his treatment was $807,086.

When McNaughton’s mother reached a United customer service representative the next day to ask why bills that had been paid in the summer were being denied for the fall, the representative told her the account was being reviewed because of “a high dollar amount on the claims,” according to a recording of the call.

Misrepresentations

With United refusing to pay, the family was terrified of being stuck with medical bills that would bankrupt them and deprive McNaugton of treatment that they considered miraculous.

They turned to Penn State for help. Light and McNaughton’s father, David, hoped their position as faculty members would make the school more willing to intervene on their behalf.

“After more than 30 years on faculty, my husband and I know that this is not how Penn State would want its students to be treated,” Light wrote to a school official in February 2021.

In response to questions from ProPublica, Penn State spokesperson Lisa Powers wrote that “supporting the health and well-being of our students is always of primary importance” and that “our hearts go out to any student and family impacted by a serious medical condition.” The university, she wrote, does “not comment on students’ individual circumstances or disclose information from their records.” McNaughton offered to grant Penn State whatever permissions it needed to speak about his case with ProPublica. The school, however, wrote that it would not comment “even if confidentiality has been waived.”

The family appealed to school administrators. Because the effectiveness of biologics wanes in some patients if doses are skipped, McNaughton and his parents were worried about even a delay in treatment. His doctor wrote that if he missed scheduled infusions of the drugs, there was “a high likelihood they would no longer be effective.”

During a conference call arranged by Penn State officials on March 5, 2021, United agreed to pay for McNaughton’s care through the end of the plan year that August. Penn State immediately notified the family of the “wonderful news” while also apologizing for “the stress this has caused Chris and your family.”

Behind the scenes, McNaughton’s review had “gone all the way to the top” at United’s student health plan division, Kavanaugh, the nurse, said in a recorded conversation.

Victoria Kavanaugh Complains to a United Contractor That McNaughton’s Coverage Request Is “Insane”

McNaughton had been on the treatment for three years and it had put his disease in remission with no side effects.

The family’s relief was short-lived. A month later, United started another review of McNaughton’s care, overseen by Kavanaugh, to determine if it would pay for the treatment in the upcoming plan year.

The nurse sent the McNaughton case to a company called Medical Review Institute of America. Insurers often turn to companies like MRIoA to review coverage decisions involving expensive treatments or specialized care.

Kavanaugh, who was assigned to a special investigations unit at United, let her feelings about the matter be known in a recorded telephone call with a representative of MRIoA.

“This school apparently is a big client of ours,” she said. She then shared her opinion of McNaughton’s treatment. “Really this is a case of a kid who’s getting a drug way too much, like too much of a dose,” Kavanaugh said. She said it was “insane that they would even think that this is reasonable” and “to be honest with you, they’re awfully pushy considering that we are paying through the end of this school year.”

Victoria Kavanaugh Describes Penn State as a “Big Account for Us”

On a call with an outside contractor, the United nurse claimed McNaughton was on a higher dose of medication than the FDA approved, which is a common practice known as “off-label prescribing.”

MRIoA sent the case to Dr. Vikas Pabby, a gastroenterologist at UCLA Health and a professor at the university’s medical school. His May 2021 review of McNaughton’s case was just one of more than 300 Pabby did for MRIoA that month, for which he was paid $23,000 in total, according to a log of his work produced in the lawsuit.

In a May 4, 2021 report, Pabby concluded McNaughton’s treatment was not medically necessary, because United’s policies for the two drugs taken by McNaughton did not support using them in combination.

Insurers spell out what services they cover in plan policies, lengthy documents that can be confusing and difficult to understand. Many policies, such as McNaughton’s, contain a provision that treatments and procedures must be “medically necessary” in order to be covered. The definition of medically necessary differs by plan. Some don’t even define the term. McNaughton’s policy contains a five-part definition, including that the treatment must be “in accordance with the standards of good medical policy” and “the most appropriate supply or level of service which can be safely provided.”

Behind the scenes at United, Opperman and Kavanaugh agreed that if McNaughton were to appeal Pabby’s decision, the insurer would simply rule against him. “I just think it’s a waste of money and time to appeal and send it to another one when we know we’re gonna get the same answer,” Opperman said, according to a recording in court files. At Opperman’s urging, United decided to skip the usual appeals process and arrange for Pabby to have a so-called “peer-to-peer” discussion with Loftus, the Mayo physician treating McNaughton. Such a conversation, in which a patient’s doctor talks with an insurance company’s doctor to advocate for the prescribed treatment, usually only occurs after a customer has appealed a denial and the appeal has been rejected.

When Kavanaugh called Loftus’ office to set up a conversation with Pabby, she explained it was an urgent matter and had been requested by McNaughton. “You know I’ve just gotten to know Christopher,” she explained, although she had never spoken with him. “We’re trying to advocate and help and get this peer-to-peer set up.”

McNaughton, meanwhile, had no idea at the time that a United doctor had decided his treatment was unnecessary and that the insurer was trying to set up a phone call with his physician.

In the peer-to-peer conversation, Loftus told Pabby that McNaughton had “a very complicated case” and that lower doses had not worked for him, according to an internal MRIoA memo.

Following his conversation with Loftus, Pabby created a second report for United. He recommended the insurer pay for both drugs, but at reduced doses. He added new language saying that the safety of using both drugs at the higher levels “is not established.”

When Kavanaugh shared the May 12 decision from Pabby with others at United, her boss responded with an email calling it “great news.”

Then Opperman sent an email that puzzled the McNaughtons.

In it, Opperman claimed that Loftus and Pabby had agreed that McNaughton should be on significantly lower doses of both drugs. He said Loftus “will work with the patient to start titrating them down” — or reducing the dosage — “to a normal dose range.” Opperman wrote that United would cover McNaughton’s treatment in the coming year, but only at the reduced doses. Opperman did not respond to emails and phone messages seeking comment.

McNaughton didn’t believe a word of it. He had already tried and failed treatment with those drugs at lower doses, and it was Loftus who had upped the doses, leading to his remission from severe colitis.

The only thing that made sense to McNaughton was that the treatment United said it would now pay for was dramatically cheaper — saving the company at least hundreds of thousands of dollars a year — than his prescribed treatment because it sliced the size of the doses by more than half.

When the family contacted Loftus for an explanation, they were outraged by what they heard. Loftus told them that he had never recommended lowering the dosage. In a letter, Loftus wrote that changing McNaughton’s treatment “would have serious detrimental effects on both his short term and long term health and could potentially involve life threatening complications. This would ultimately incur far greater medical costs. Chris was on the doses suggested by United Healthcare before, and they were not at all effective.”

It would not be until the lawsuit that it would become clear how Loftus’ conversations had been so seriously misrepresented.

Under questioning by McNaughton’s lawyers, Kavanaugh acknowledged that she was the source of the incorrect claim that McNaughton’s doctor had agreed to a change in treatment.

“I incorrectly made an assumption that they had come to some sort of agreement,” she said in a deposition last August. “It was my first peer-to-peer. I did not realize that that simply does not occur.”

Kavanaugh did not respond to emails and telephone messages seeking comment.

When the McNaughtons first learned of Opperman’s inaccurate report of the phone call with Loftus, it unnerved them. They started to question if their case would be fairly reviewed.

“When we got the denial and they lied about what Dr. Loftus said, it just hit me that none of this matters,” McNaughton said. “They will just say or do anything to get rid of me. It delegitimized the entire review process. When I got that denial, I was crushed.”

A Buried Report

While the family tried to sort out the inaccurate report, United continued putting the McNaughton case in front of more company doctors.

On May 21, 2021, United sent the case to one of its own doctors, Dr. Nady Cates, for an additional review. The review was marked “escalated issue.” Cates is a United medical director, a title used by many insurers for physicians who review cases. It is work he has been doing as an employee of health insurers since 1989 and at United since 2010. He has not practiced medicine since the early 1990s.

Cates, in a deposition, said he stopped seeing patients because of the long hours involved and because “AIDS was coming around then. I was seeing a lot of military folks who had venereal diseases, and I guess I was concerned about being exposed.” He transitioned to reviewing paperwork for the insurance industry, he said, because “I guess I was a chicken.”

When he had practiced, Cates said, he hadn’t treated patients with ulcerative colitis and had referred those cases to a gastroenterologist.

He said his review of McNaughton’s case primarily involved reading a United nurse’s recommendation to deny his care and making sure “that there wasn't a decimal place that was out of line.” He said he copied and pasted the nurse’s recommendation and typed “agree” on his review of McNaughton’s case.

Dr. Nady Cates, a United Medical Director, Explains That He Copied and Pasted the Text of His Decision to Deny McNaughton’s Care

In the deposition, Cates tells McNaughton’s lawyer that he copied the recommendation of Pamela Banister, a nurse for United, rather than writing his own decision.

Cates said that he does about a hundred reviews a week. He said that in his reviews he typically checks to see if any medications are prescribed in accordance with the insurer’s guidelines, and if not, he denies it. United’s policies, he said, prevented him from considering that McNaughton had failed other treatments or that Loftus was a leading expert in his field.

“You are giving zero weight to the treating doctor’s opinion on the necessity of the treatment regimen?” a lawyer asked Cates in his deposition. He responded, “Yeah.”

Attempts to contact Cates for comment were unsuccessful.

At the same time Cates was looking at McNaughton’s case, yet another review was underway at MRIoA. United said it sent the case back to MRIoA after the insurer received the letter from Loftus warning of the life-threatening complications that might occur if the dosages were reduced.

On May 24, 2021, the new report requested by MRIoA arrived. It came to a completely different conclusion than all of the previous reviews.

Dr. Nitin Kumar, a gastroenterologist in Illinois, concluded that McNaughton’s established treatment plan was not only medically necessary and appropriate but that lowering his doses “can result in a lack of effective therapy of Ulcerative Colitis, with complications of uncontrolled disease (including dysplasia leading to colorectal cancer), flare, hospitalization, need for surgery, and toxic megacolon.”

Unlike other doctors who produced reports for United, Kumar discussed the harm that McNaughton might suffer if United required him to change his treatment. “His disease is significantly severe, with diagnosis at a young age,” Kumar wrote. “He has failed every biologic medication class recommended by guidelines. Therefore, guidelines can no longer be applied in this case.” He cited six studies of patients using two biologic drugs together and wrote that they revealed no significant safety issues and found the therapy to be “broadly successful.”

When Kavanaugh learned of Kumar’s report, she quickly moved to quash it and get the case returned to Pabby, according to her deposition.

In a recorded telephone call, Kavanaugh told an MRIoA representative that “I had asked that this go back through Dr. Pabby, and it went through a different doctor and they had a much different result.” After further discussion, the MRIoA representative agreed to send the case back to Pabby. “I appreciate that,” Kavanaugh replied. “I just want to make sure, because, I mean, it’s obviously a very different result than what we’ve been getting on this case.”

MRIoA case notes show that at 7:04 a.m. on May 25, 2021, Pabby was assigned to take a look at the case for the third time. At 7:27 a.m., the notes indicate, Pabby again rejected McNaughton’s treatment plan. While noting it was “difficult to control” McNaughton’s ulcerative colitis, Pabby added that his doses “far exceed what is approved by literature” and that the “safety of the requested doses is not supported by literature.”

In a deposition, Kavanaugh said that after she opened the Kumar report and read that he was supporting McNaughton’s current treatment plan, she immediately spoke to her supervisor, who told her to call MRIoA and have the case sent back to Pabby for review.

Kavanaugh said she didn’t save a copy of the Kumar report, nor did she forward it to anyone at United or to officials at Penn State who had been inquiring about the McNaughton case. “I didn’t because it shouldn’t have existed,” she said. “It should have gone back to Dr. Pabby.”

When asked if the Kumar report caused her any concerns given his warning that McNaughton risked cancer or hospitalization if his regimen were changed, Kavanaugh said she didn’t read his full report. “I saw that it was not the correct doctor, I saw the initial outcome and I was asked to send it back,” she said. Kavanaugh added, “I have a lot of empathy for this member, but it needed to go back to the peer-to-peer reviewer.”

In a court filing, United said Kavanaugh was correct in insisting that Pabby conduct the review and that MRIoA confirmed that Pabby should have been the one doing the review.

The Kumar report was not provided to McNaughton when his lawyer, Jonathan Gesk, first asked United and MRIoA for any reviews of the case. Gesk discovered it by accident when he was listening to a recorded telephone call produced by United in which Kavanaugh mentioned a report number Gesk had not heard before. He then called MRIoA, which confirmed the report existed and eventually provided it to him.

Pabby asked ProPublica to direct any questions about his involvement in the matter to MRIoA. The company did not respond to questions from ProPublica about the case.

A Sense of Hopelessness

When McNaughton enrolled at Penn State in 2020, it brought a sense of normalcy that he had lost when he was first diagnosed with colitis. He still needed monthly hours-long infusions and suffered occasional flare-ups and symptoms, but he was attending classes in person and living a life similar to the one he had before his diagnosis.

It was a striking contrast to the previous six years, which he had spent largely confined to his parents’ house in State College. The frequent bouts of diarrhea made it difficult to go out. He didn’t talk much to friends and spent as much time as he could studying potential treatments and reviewing ongoing clinical trials. He tried to keep up with the occasional online course, but his disease made it difficult to make any real progress toward a degree.

United, in correspondence with McNaughton, noted that its review of his care was “not a treatment decision. Treatment decisions are made between you and your physician.” But by threatening not to pay for his medications, or only to pay for a different regimen, McNaughton said, United was in fact attempting to dictate his treatment. From his perspective, the insurer was playing doctor, making decisions without ever examining him or even speaking to him.

The idea of changing his treatment or stopping it altogether caused constant worry for McNaughton, exacerbating his colitis and triggering physical symptoms, according to his doctors. Those included a large ulcer on his leg and welts under his skin on his thighs and shin that made his leg muscles stiff and painful to the point where he couldn’t bend his leg or walk properly. There were daily migraines and severe stomach pain. “I was consumed with this situation,” McNaughton said. “My path was unconventional, but I was proud of myself for fighting back and finishing school and getting my life back on track. I thought they were singling me out. My biggest fear was going back to the hell.”

McNaughton said he contemplated suicide on several occasions, dreading a return to a life where he was housebound or hospitalized.

McNaughton and his parents talked about him possibly moving to Canada where his grandmother lived and seeking treatment there under the nation’s government health plan.

Loftus connected McNaughton with a psychologist who specializes in helping patients with chronic digestive diseases.

The psychologist, Tiffany Taft, said McNaughton was not an unusual case. About 1 in 3 patients with diseases like colitis suffer from medical trauma or PTSD related to it, she said, often the result of issues related to getting appropriate treatment approved by insurers.

“You get into hopelessness,” she said of the depression that accompanies fighting with insurance companies over care. “They feel like ‘I can’t fix that. I am screwed.’ When you can’t control things with what an insurance company is doing, anxiety, PTSD and depression get mixed together.”

In the case of McNaughton, Taft said, he was being treated by one of the best gastroenterologists in the world, was doing well with his treatment and then was suddenly notified he might be on the hook for nearly a million dollars in medical charges without access to his medications. “It sends you immediately into panic about all these horrific things that could happen,” Taft said. The physical and mental symptoms McNaughton suffered after his care was threatened were “triggered” by the stress he experienced, she said.

In early June 2021, United informed McNaughton in a letter that it would not cover the cost of his treatment regimen in the next academic year, starting in August. The insurer said it would only pay for a treatment plan that called for a significant reduction in the doses of the drugs he took.

United wrote that the decision came after his “records have been reviewed three times and the medical reviewers have concluded that the medication as prescribed does not meet the Medical Necessity requirement of the plan.”

In August 2021, McNaughton filed a federal lawsuit accusing United of acting in bad faith and unreasonably making treatment decisions based on financial concerns and not what was the best and most effective treatment. It claims United had a duty to find information that supported McNaughton’s claim for treatment rather than looking for ways to deny coverage.

United, in a court filing, said it did not breach any duty it owed to McNaughton and acted in good faith. On Sept. 20, 2021, a month after filing the lawsuit, and with United again balking at paying for his treatment, McNaughton asked a judge to grant a temporary restraining order requiring United to pay for his care. With the looming threat of a court hearing on the motion, United quickly agreed to cover the cost of McNaughton’s treatment through the end of the 2021-2022 academic year. It also dropped a demand requiring McNaughton to settle the matter as a condition of the insurer paying for his treatment as prescribed by Loftus, according to an email sent by United’s lawyer.

The Cost of Treatment

It is not surprising that insurers are carefully scrutinizing the care of patients treated with biologics, which are among the most expensive medications on the market. Biologics are considered specialty drugs, a class that includes the best-selling Humira, used to treat arthritis. Specialty drug spending in the U.S. is expected to reach $505 billion in 2023, according to an estimate from Optum, United’s health services division. The Institute for Clinical and Economic Review, a nonprofit that analyzes the value of drugs, found in 2020 that the biologic drugs used to treat patients like McNaughton are often effective but overpriced for their therapeutic benefit. To be judged cost-effective by ICER, the biologics should sell at a steep discount to their current market price, the panel found.

A panel convened by ICER to review its analysis cautioned that insurance coverage “should be structured to prevent situations in which patients are forced to choose a treatment approach on the basis of cost.” ICER also found examples where insurance company policies failed to keep pace with updates to clinical practice guidelines based on emerging research.

United officials did not make the cost of treatment an issue when discussing McNaughton’s care with Penn State administrators or the family.

Bill Truxal, the president of UnitedHealthcare StudentResources, the company’s student health plan division, told a Penn State official that the insurer wanted the “best for the student” and it had “nothing to do with cost,” according to notes the official took of the conversation.

Behind the scenes, however, the price of McNaughton’s care was front and center at United.

In one email, Opperman asked about the cost difference if the insurer insisted on only paying for greatly reduced doses of the biologic drugs. Kavanaugh responded that the insurer had paid $1.1 million in claims for McNaughton’s care as of the middle of May 2021. If the reduced doses had been in place, the amount would have been cut to $260,218, she wrote.

United was keeping close tabs on McNaughton at the highest levels of the company. On Aug. 2, 2021, Opperman notified Truxal and a United lawyer that McNaughton “has just purchased the plan again for the 21-22 school year.”

A month later, Kavanaugh shared another calculation with United executives showing that the insurer spent over $1.7 million on McNaughton in the prior plan year.

United officials strategized about how to best explain why it was reviewing McNaughton’s drug regimen, according to an internal email. They pointed to a justification often used by health insurers when denying claims. “As the cost of healthcare continues to climb to soaring heights, it has been determined that a judicious review of these drugs should be included” in order to “make healthcare more affordable for our members,” Kavanaugh offered as a potential talking point in an April 23, 2021, email.

Three days later, UnitedHealth Group filed an annual statement with the U.S. Securities and Exchange Commission disclosing its pay for top executives in the prior year. Then-CEO David Wichmann was paid $17.9 million in salary and other compensation in 2020. Wichmann retired early the following year, and his total compensation that year exceeded $140 million, according to calculations in a compensation database maintained by the Star Tribune in Minneapolis. The newspaper said the amount was the most paid to an executive in the state since it started tracking pay more than two decades ago. About $110 million of that total came from Wichmann exercising stock options accumulated during his stewardship.

The McNaughtons were well aware of the financial situation at United. They looked at publicly available financial results and annual reports. Last year, United reported a profit of $20.1 billion on revenues of $324.2 billion.

When discussing the case with Penn State, Light said, she told university administrators that United could pay for a year of her son’s treatment using just minutes’ worth of profit.

“Betrayed”

McNaughton has been able to continue receiving his infusions for now, anyway. In October, United notified him it was once again reviewing his care, although the insurer quickly reversed course when his lawyer intervened. United, in a court filing, said the review was a mistake and that it had erred in putting McNaughton’s claims into pending status.

McNaughton said he is fortunate his parents were employed at the same school he was attending, which was critical in getting the attention of administrators there. But that help had its limits.

In June 2021, just a week after United told McNaughton it would not cover his treatment plan in the upcoming plan year, Penn State essentially walked away from the matter.

In an email to the McNaughtons and United, Penn State Associate Vice President for Student Affairs Andrea Dowhower wrote that administrators “have observed an unfortunate breakdown in communication” between McNaughton and his family and the university health insurance plan, “which appears from our perspective to have resulted in a standstill between the two parties.” While she proposed some potential steps to help settle the matter, she wrote that “Penn State’s role in this process is as a resource for students like Chris who, for whatever reason, have experienced difficulty navigating the complex world of health insurance.” The university’s role “is limited,” she wrote, and the school “simply must leave” the issue of the best treatment for McNaughton to “the appropriate health care professionals.”

In a statement, a Penn State spokesperson wrote that “as a third party in this arrangement, the University’s role is limited and Penn State officials can only help a student manage an issue based on information that a student/family, medical personnel, and/or insurance provider give — with the hope that all information is accurate and that the lines of communication remain open between the insured and the insurer.”

Penn State declined to provide financial information about the plan. However, the university and United share at least one tie that they have not publicly disclosed.

When the McNaughtons first reached out to the university for help, they were referred to the school’s student health insurance coordinator. The official, Heather Klinger, wrote in an email to the family in February 2021 that “I appreciate your trusting me to resolve this for you.”

In April 2022, United began paying Klinger’s salary, an arrangement which is not noted on the university website. Klinger appears in the online staff directory on the Penn State University Health Services webpage, and has a university phone number, a university address and a Penn State email listed as her contact. The school said she has maintained a part-time status with the university to allow her to access relevant data systems at both the university and United.

The university said students “benefit” from having a United employee to handle questions about insurance coverage and that the arrangement is “not uncommon” for student health plans.

The family was dismayed to learn that Klinger was now a full-time employee of United.

“We did feel betrayed,” Light said. Klinger did not respond to an email seeking comment.

McNaughton’s fight to maintain his treatment regimen has come at a cost of time, debilitating stress and depression. “My biggest fear is realizing I might have to do this every year of my life,” he said.

McNaughton said one motivation for his lawsuit was to expose how insurers like United make decisions about what care they will pay for and what they will not. The case remains pending, a court docket shows.

He has been accepted to Penn State’s law school. He hopes to become a health care lawyer working for patients who find themselves in situations similar to his.

He plans to reenroll in the United health care plan when he starts school next fall.

Effect of Food Order on Ghrelin Suppression

Some years back a study was done comparing how one ate the same meal made a difference is your metabolism.  Now a more specific evaluation on one of the components of that metabolism was evaluated and found to be affected in no surprise.  I thought, though, this gave me an opportunity to review the earlier information, because it’s just SO important for everyone to understand.  

You go into a nice Italian restaurant, and they have great bread.  You love the bread, but you figure you’re watching your diet, so you’ll only have the bread – no oil or butter.  WRONG!!  Literally, the worst thing you can do.  Why?  

Restaurants know from years of experience, giving bread before the meal MAKES PEOPLE ORDER MORE FOOD.  Turns out that the carbohydrate load minutes before consuming any other macronutrient (think protein, fat, carbs) will drive up your blood sugar to astronomical heights, and thus driving up insulin levels, and that elevation will persist for hours.  This combination leads to “overeating”.  You’re priming the pump for pre-diabetes.

If start the meal with bread AND butter or olive oil, that fat will actually work in your favor to slow the carbohydrate absorption, blunt your sugar elevation, blunt your insulin response, which results in 40% lower levels and a far lower chance of driving that pre-diabetes story.  

Now, of course, if you eat all the bread, all the food, and the dessert, all bets are off!  But if you want to have a piece of that delicious bread, do yourself a favor – dip it in some olive oil, or if they have really good, yellow butter (like Kerry Gold), go for it!  

Now THAT’S A CRAZY STORY!  (but true 😉)

FROM DIABETES CARE / BY ALPANA P. SHUKLA, ELIZABETH MAUER, LEON I. IGEL, WANDA TRUONG, ANTHONY CASPER, REKHA B. KUMAR, KATHERINE H. SAUNDERS, LOUIS J. ARONNE

Data suggest that the temporal sequence of carbohydrate ingestion during a meal has a significant impact on postprandial glucose 1-3), insulin, and glucagon-like peptide 1 (GLP-1) excursions (4) in type 2 diabetes, while the effects on ghrelin suppression and satiety have not been reported.

The study design and methods have previously been described in detail (4). Briefly, using a crossover design, 16 subjects with overweight/obesity and metformin-treated type 2 diabetes were assigned to consume the same meal on 3 days in random order:

  • Carbohydrate-first meal: carbohydrate (bread and orange juice), followed 10 min later by protein (chicken) and vegetables

  • Carbohydrate-last meal: protein and vegetables, followed 10 min later by carbohydrate

  • Sandwich: all meal components together, each half consumed over 10 min with a 10-min interval in between

Blood was sampled for glucose, insulin, active GLP-1, and total ghrelin measurements at baseline (just before meal ingestion) and at 30-min intervals up to 180 min. Participants rated their hunger and fullness levels using a visual analog scale (VAS) at the same time points.

Baseline glucose, insulin, GLP-1, and ghrelin concentrations, as well as hunger and satiety scores, were similar in the three meal conditions. At 180 min, ghrelin levels remained suppressed following the carbohydrate-last meal order, while the carbohydrate-first meal led to a rebound in ghrelin to preprandial levels (percent ghrelin change from baseline to 180 min −11.45 ± 3.86% vs. 4.13 ± 4.38%; P = 0.003) (Fig. 1). Decremental areas under the curve for 0–180 min were similar in the three meal conditions. There was an inverse correlation between percent change in ghrelin and percent change in glucose from baseline when assessing all participants in the three meal conditions at the evaluated time points (r = −0.204; P < 0.001). We did not observe a significant effect of food order on subjective VAS appetite measures.

Ghrelin percent change from baseline following carbohydrate-first (carbs first), carbohydrate-last (carbs last), and sandwich meal orders. Values are mean ± SEM, n = 16. ¥Statistically significant difference (P = 0.003, linear mixed-effects model) between carbs first and carbs last at 180 min.

We have previously demonstrated that the carbohydrate-last meal pattern reduces postprandial glucose excursions compared with other meal patterns. Controlling for carbohydrate amount, this meal pattern stimulates lower insulin and higher GLP-1 response compared with the carbohydrate-first pattern (4). Taken together with our new findings on ghrelin suppression, this suggests that macronutrient order during a meal modifies the pattern of postprandial insulin and gut hormone secretion that could potentially impact satiety and weight regulation. However, similar to observations in previous studies that have investigated gut hormone excursions to isocaloric meal interventions (5,6), these disparate hormonal responses did not translate into any significant differences in hunger/satiety scores reported by participants in the three meal conditions. This result may reflect both the subjective nature of the VAS tool and the complexity of appetite regulation; ghrelin is the only known orexigenic peptide, whereas GLP-1 is one of several anorexigenic signaling gut hormones. Further study with an extended observation period, assessment of other gut hormones using meals with different macronutrient composition, and more objective measures of satiety is needed.

In conclusion, to our knowledge, this is the first study to demonstrate that manipulation of macronutrient order can impact gut hormone excursions. Its clinical implications for satiety and weight management require further study.

Dementia Tied to Hearing Loss

It’s well known that losing senses translates to increased incidence of dementia.  It seems like losing contact with one’s environment translates into accelerated loss of a functional brain.  Think about kids who don’t get stimulated adequately – they end up being delayed or cognitively impaired.  Same thing ends up happening at the other end – less stimulation ends up in the idea of “use it or lose it”.  Your brain starts to deteriorate at a faster rate if it’s not getting “poked” regularly.  This happens as eyesight fails (cataracts contribute to dementia), social isolation, and hearing loss.  The important finding here, though, is that hearing aids actually drops that risk back to a usual level, and might actually decrease the risk of developing dementia slightly.  You hear what I’m saying? 😉

If you hear yourself saying “what?” a bunch, get your hearing checked and get some hearing aids.  If your vision is failing, get it checked and maybe get your cataracts fixed.  Don’t sit home alone – make some friends!  All these simple things could really save you. 

— Likelihood of developing dementia was lower for older adults who used hearing aids

Moderate-to-severe hearing loss was linked with a higher prevalence of dementia, a cross-sectional study of Medicare beneficiaries showed.

Among 2,413 older adults in the National Health and Aging Trends Study (NHATS), dementia prevalence among people with moderate-to-severe hearing loss was higher than it was among people with normal hearing (prevalence ratio 1.61, 95% CI 1.09-2.38), reported Nicholas Reed, AuD, of the Johns Hopkins Bloomberg School of Public Health in Baltimore, and colleagues.

But among people with moderate-to-severe hearing loss in the study, hearing aid use was associated with a lower prevalence of dementia compared with no hearing aid use (prevalence ratio 0.68, 95% CI 0.47-1.00), they wrote in a JAMA research letter.

The findings support a recent systematic review and meta-analysis that showed treating hearing loss led to cognitive benefits. They also support the availability of over-the-counter hearing aids, which people with mild-to-moderate hearing loss now can purchase directly due to new regulations.

Reed and colleagues used data from the continuous NHATS panel study of Medicare beneficiaries. The NHATS cohort was oversampled for age (53.3% were 80 or older) and race (18.8% were Black). Participant information collected through in-home interviews.

Hearing was assessed with a portable audiometer. Researchers calculated a pure tone average in the better-hearing ear as the mean of four frequencies -- 500, 1,000, 2,000, and 4,000 Hz -- most important for understanding speech.

Normal hearing was defined as a pure tone average of 25 dB or less, mild hearing loss was 26-40 dB, and moderate-to-severe loss was over 40 dB. About a third of participants (33.47%) had normal hearing after weighting; 36.74% had mild hearing loss, and 29.79% had moderate-to-severe loss. People with moderate-to-severe hearing loss tended to be older, male, and white, and had less education than others.

The weighted prevalence of dementia was 10.27% overall. Dementia prevalence rose as severity of hearing loss increased: for normal hearing, it was 6.19%; for mild hearing loss, it was 8.93%; and for moderate-to-severe hearing loss, it was 16.52%.

The study's cross-sectional design was a limitation. In addition, nursing home and residential care residents were excluded from the analysis because the researchers did not have cognitive data about them.

The top modifiable risk factor for dementia prevention is hearing loss, which accounts for 8% of the global dementia burden according to a recent Lancet Commission report.

"This study refines what we've observed about the link between hearing loss and dementia, and builds support for public health action to improve hearing care access," co-author Alison Huang, PhD, also of Johns Hopkins, said in a statement.

How hearing loss is linked to dementia isn't clear and studies point to several possible mechanisms. "Mediation analyses to characterize mechanisms underlying the association and randomized trials to determine the effects of hearing interventions on reducing dementia risk are needed," Reed and colleagues wrote.

Information about hearing loss treatment and cognition from the 3-year randomized ACHIEVE trial is expected later this year.

This 5-Word Sentence Is Killing Your Ability to Be Happy. Everyone Says It

Not if you repeat this mantra.  The very statement tells the story – we get to choose to be happy, it’s not a desire.  It’s a choice.  As most ancient Eastern religions will tell us – pain is part of being human, suffering is not.  Acceptance is key.  The same is true with happiness.  It’s intrinsic to being human; it’s all the stuff we put on ourselves that creates issues that somehow we have to combat.  NO!  Other studies have shown that even goal achievement won’t keep us happy.  The pleasure of the achievement is, by it’s very nature, transient.  We need to keep striving, never fully satisfied.  So, again, that won’t make you happy.  

Take some deep breaths.  View the world as what you have, not what’s missing.  The shift will literally change your whole world.

FROM INC MAGAZINE / BY KELLY MAIN

Here's what science says to say instead to instantly increase your happiness.

We all want to be happy. Yet happiness can often feel fleeting and largely elusive. But as much as the path to happiness remains a mystery, the answer might actually prove surprisingly simple. 

It's not about gratitude, wavering focus, or even diminishing effort. But it does start with a simple, five-word sentence that most of us have muttered at one point or another: 

"I want to be happy." Or perhaps some variation, such as "I want to be happier."

Either way, if you want to be happy, you need to stop saying this well-meaning but devilishly deceptive sentence that plagues us all. Because in a bid to find happiness, it might be the very reason happiness escapes us. 

At one point or another, we've heard that the first step to making meaningful progress is making bold declarations and setting even bolder goals to match. Our culture is riddled with motivational mantras such as, "go big or go home," "go for the gusto," and "shoot for the moon." 

We know that goals should be big-and how much bigger does it get than the goal of happiness? 

Lofty goals are what drive innovation and it's the core of Google's O2-Plus method that fuels massive growth without causing burnout. The path to happiness isn't the same as innovation--yet it does entail another aspect of the strategy: effective goal setting. 

When it comes to learning how to increase your happiness, setting your sights on the big, overarching goal of sheer happiness is adding fuel to the fire and igniting just the opposite result: unhappiness. 

Science, psychology, and philosophy agree: The pursuit of happiness kills happiness

The idea that true happiness comes from within, and that it's not something that can be pursued or attained, is not solely an ancient philosophy. The field of modern science concurs. 

Neuroscience has long since agreed that when it comes to happiness, finding true joy cannot be achieved through seeking it out. Studies have found that the more a person is focused on chasing happiness and contentment, the less likely they are to find it. So much so that studies have found that the pursuit of happiness is actually making us miserable.

What they do find is a lack of time. According to a study published by Science Daily. researchers found that "people who pursue happiness often feel like they do not have enough time in the day, and this paradoxically makes them feel unhappy." 

But that doesn't mean the quest for happiness is a futile pursuit. 

Happiness isn't a goal--it's the byproduct of a goal 

It means it should simply be approached differently. With the use of effective goal-setting, you wouldn't merely declare that you want to be happier. Instead, you would declare that you want to pursue the things that (in turn) make you happy.

This approach to goal-setting is vital to both goal-setting and setting yourself up for successful goal attainment. Rather than having a lofty, overarching goal (e.g., I want to make more money), develop goals that have a clear path to attainment (e.g., I want to grow my business). It's the art of looking not at the "what" (e.g., making more money), but of focusing on the "how" (growing the business). 

In doing so, it provides a clear path to the goal. And the more focused you can make the goal, the more likely you are to achieve not only the goal, but also happiness along the way. 

Set yourself up for happiness

By focusing on smaller, more realistic goals that are within reach, you can make meaningful progress in the pursuit of them. In the process, you'll be more likely to set yourself up for success--and happiness.    

For example, let's say, you want a promotion. But what's the path to it? 

It could be further developing your skills or knowledge in the field, supercharging your productivity, or perhaps strengthening your network and improving your networking skills. All of which can help you get a promotion at work. And if not, it will help position you to get into another organization, and perhaps a higher position within it.

So stop killing your ability to be happy by saying you want to be happier. 

Instead, try making your goal something other than pure happiness, but something that will increase your happiness during the pursuit of it. Try saying things like "I want to become an expert in my field," "I want to finally write that book," "I want to invest in myself and my passions," "I want to spend more time with my family," or "I want to be a better boss/friend/partner/parent."

When we stop making happiness the goal, and instead make our goal something that will contribute to our happiness, we find happiness.

Can Just Minutes of Daily Activity Prolong Life?

Doc, Do I really have to Exercise?  YES - but's not what you think.

Great news for the couch potatoes in all of us.  In a study of over 25,000 sedentary older adults (average age 62, no regular “exercise”) over years , it was found that these individuals had a 39% lower risk of dying if they simply did 3 bouts of vigorous activity for about 2 minutes each during the day.  Vigorous intensity physical activity includes short burst of fast walking (like commuting), or climbing a set of stairs.  Most people did about 5 minutes a day of vigorous activity and 28 minutes of moderate activity, despite doing “no exercise.”

Even doing 1 ½ minutes 3 times a day translated into a 25% reduction.  Of course, if you want to get crazy, doing a total of 16 minutes (11 bouts in a day) topped them all with a 48% reduction!!  There were clear decreases in death specifically from heart disease as well.

On average, 3 1-minute bouts of vigorous activity dropped cardiovascular death by 49%.  The maximum group saw a 65% drop.  Cancer mortality have similar kinds of drops. 

How do we make sure we’re doing enough?  Actually, it’s pretty easy.  Walk a little faster when you’re walking, carry your groceries to the car, park away from the entrance in a lot and walk a little, take the stairs.  You’ve heard all these before – but now we can PROVE there’s a benefit!   GET TO IT!  Live longer, live better.

Benefits included all-cause, heart, and cancer-related mortality risk reduction

Even short bouts of physical activity in an otherwise sedentary lifestyle were associated with a significantly lower risk for dying, researchers reported.

In a study of more than 25,000 older adults who didn't regularly exercise, engaging in a median of just three bouts of vigorous activity for up to 2 minutes each at some point during the day was linked with a 39% lower risk for all-cause mortality versus no activity at all (HR 0.61, 95% CI 0.50-0.74), according to Emmanuel Stamatakis, PhD, of the University of Sydney in Australia, and colleagues.

Even the minimum of 1.5 minute-long bouts of exercise per day reaped mortality benefits compared with not engaging in any activity at all (HR 0.75, 95% CI 0.66-0.85). But those at the top of the range in this cohort -- getting 11 short bursts of vigorous activity daily (about 16 minutes total) -- saw all-cause mortality risk drop by even more (HR 0.52, 95% CI 0.37-0.72).

Beyond all-cause mortality benefits, engaging in just a few minutes of vigorous intermittent lifestyle physical activity (VILPA) throughout the day was also protective against cardiovascular disease-related mortality, the group reported in Nature Medicineopens in a new tab or window.

Engaging in the median frequency of three 1-minute bouts per day was linked with a 49% lower cardiovascular mortality risk (HR 0.51, 95% CI 0.35-0.74). Again, those that engaged in the maximum frequency saw the biggest benefit (HR 0.35, 95% CI 0.15-0.81). But even engaging in the minimum was still significantly protective against heart-related death (HR 0.67, 95% CI 0.52-0.86).

Stamatakis's group also found the same pattern in regards to cancer-related mortality risk.

"We found that as little as 3 to 4 minutes of VILPA per day was associated with substantially reduced mortality risk compared to doing no VILPA," Stamatakis told MedPage Today, noting how these were "very sizeable effect sizes."

"We were not surprised that we detected beneficial associations; we knew that vigorous physical activity is very potent, especially when it is intermittent and repeated," he said. "But the large magnitude of the associations was quite surprising, considering how little daily physical activity we are talking about."

"Interestingly, is not unlikely that participants in this study did not know that they were doing vigorous physical activity," Stamatakis pointed out.

Participants in the study cohort appeared in the U.K. Biobank, including 14,178 women and 11,063 men with an average age of 62. Over the 7-year follow-up period, 852 deaths occurred. The sample was exclusive to those who said they didn't engage in regular exercise. This meant they didn't have a regular fitness routine, didn't participate in sports, and only walked for recreation no more than once per week. All adults wore an accelerometer to track activity.

These short bursts of vigorous-intensity physical activity were considered a part of daily life. They included instances of short bursts of fast walking during a commute or climbing a set of stairs, for example. Those who engaged in three to four bouts of doing 1-minute of vigorous activity accumulated a median of 4.7 minutes per day of vigorous activity and 27.9 minutes of moderate activity per day.

"The world is experiencing an unending pandemic of lifestyle related chronic disease, and physical inactivity is one of its main driving forces," Stamatakis explained. "The healthcare systems have a key role to play. Health professionals are a trusted source of information and advice to help people prevent or delay the onset of chronic disease and increase their health span.

"Most healthcare professionals, however," he said, "are not trained or educated to offer physical activity advice, especially when it comes to encouraging initiation and adherence to a leisure-time exercise program, because the participation bar for leisure time exercise is too high: it demands high levels of motivation, time availability, capacity and willingness to travel to an exercise club or park, and many other conditions that can only be met by a small minority of middle aged and older adults."

But based on these study results, he explained that healthcare professionals can opt to take a different approach to advocating for physical activity.

"For example, what opportunities exist during everyday life for short bursts of VILPA, such as maximizing the walking pace for a minute or 2 during any regular walk, manually carrying groceries from the supermarket to the carpark, using stairs instead of elevators, replacing short car trips -- e.g. less than 1 km [0.62 miles] -- with very fast walking, or parking the car a few hundred meters away and instead walking fast to the final destination," he suggested as tips to provide to patients.

"Provided that this kind of behavior becomes regular and habitual in the long term, there is a good chance it will be followed by health benefits," said Stamatakis.

Rigid In-Hospital Diet Offers No Advantage in Patients After HSCT

When patients get bone marrow transplants their immune systems are wrecked for a while.  As a consequence, they get infected pretty easily.  The thinking has been that we should protect them with a special diet – cook everything to 175 degrees, so nothing alive will get into their system.  The problem is that when you cook everything to 175 degrees, it turns to mush.  Kinda gross, especially if everything you eat looks like that.  Somebody finally asked the question – can these folks eat real food and not get sick(er)?  Turns out that they absolutely can.  If you were as sick as you could possibly be and people told you that you had to eat gruel, you would.  But if you could actually eat real food, that might just be something to look forward to.  In any event, the assumption that the food HAD to be sterilized completely turns out not to make a difference.  But if we don’t ask, we never know.  Lots of things in medicine are assumed for a very long time.  Often the question is never asked.  I think we should ask those questions more.  We might just learn something, and it might just surprise us.

Patients who have neutropenia after undergoing hematopoietic stem cell transplantation (HSCT) do not need to restrict themselves to unpalatable hospital foods, a researcher said here.

A randomized study of over 200 patients with hematologic diseases showed that patients who received a non-restrictive diet -- including fresh fruits and vegetables, cold cuts, and pasteurized honey and yogurt -- after autologous or allogeneic HSCT did not have an increased risk of infection compared with patients who had a restrictive neutropenic diet. The latter only allows foods that have been cooked to about 175° F, reported Federico Stella, MD, of the Università degli Studi di Milano -- Istituto Nazionale dei Tumori in Milan, at the American Society of Hematologyopens in a new tab or window (ASH) annual meeting.

Up to 30 days following autologous HSCT, and 100 days after allogeneic HSCT, infections grade ≥2 were observed in 65% of patients on the protective neutropenic diet and 62% of patients on the non-restrictive diet (relative risk 1.0, 95% CI 0.8-1.3, P=0.8), Stella and colleagues found. They also noted that the incidence of fever of unknown origin, including febrile neutropenia, was comparable between the protective and non-restrictive diet arms at 43% versus 39%, respectively (RR 1.3, 95% CI 0.9-1.7, P=0.2).

And the incidence of sepsis was also similar between protective and non-restrictive diet arms (11% vs 14%, RR 0.7, 95% CI 0.4-1.5, P=0.5).

"The results of this first randomized study investigating the role of diet after allogeneic and autologous stem cell transplant demonstrate that the use of a restrictive diet is an unnecessary burden for patients quality of life," Stella said during an ASH press briefing.

He pointed out that infections are a frequent complication after HSCT. "Among measures applied to prevent infections, the use of a low microbial protective diet is standard of care adopted in more than 90% of bone marrow transplantations," he said, adding that the efficacy of this approach has not been prospectively evaluated.

"I love this [study] because of how it upends the dogma," said press briefing moderator Mikkael Sekeres, MD, MS, of the University of Miami Miller School of Medicine. "For decades, we have been essentially feeding patients gruel in the hospital under the auspices of a neutropenic diet. And the theory is a good one – that we are minimizing the risk of infections in people who are severely immunocompromised. And we do this in bone marrow transplant units and leukemia units where patients are hospitalized for 4 to 6 weeks."

However, relegating these patients to these restrictive diets has never made sense, Sekeres said: "I've never seen a patient die from an infection that was foodborne."

Trial patients were randomized 1:1 to the two arms (112 patients in each). Among all the patients, 37% had lymphomas, 38% multiple myeloma, and 5% acute myeloid leukemia. Most (76%) received autologous HSCT and 21% received allogeneic HSCT. Patients followed their assigned diet from the start of chemotherapy (before transplant) until their white blood cell count recovered after the procedure.

Stella also reported there were no significant differences between the protective diet and non-restrictive diets, respectively, for:

  • Body weight variations: mean -3.6 kg (about 1 lb) vs -3.2 kg (P=0.33)

  • Incidence of nausea: 16% vs 15% (RR 1.1, 95% CI 0.6-1.9, P>0.99)

  • Mucositis: 62% vs 60% (RR 1.05, 95% CI 0.8-1.3, P=0.8)

  • Hospitalization length: mean 21 days vs 22 days (P=0.47)

  • Parenteral nutrition use: 23% vs 26% (RR 0.9, 95% CI 0.4-1.4, P=0.8)

  • Parenteral nutrition duration: mean 6.9 days vs 6.7 days (P=0.8)

  • Acute graft-versus-host disease grade ≥2 in allogeneic-HSCT patients: 17% vs 25% (RR 0.7, 95% CI 0.2-2, P=0.7).

Importantly, Stella observed, "the non-restrictive diet was associated with higher satisfaction in a patient-reported quality of life analysis." Specifically, just 16% of patients on the protective diet reported it did not negatively impact their care and feeding versus 35% in the non-restrictive diet arm (RR 0.5, 95% CI 0.3-0.8, P=0.006).

When asked whether a change in accepted dietary practice for these patients would meet resistance, Sekeres noted that while working at another center, he eliminated the neutropenic diet on the leukemia floor, and that did "face a lot of resistance as you can imagine -- this is decades of people saying we should do this."

He called food an "emotional" issue, and said that patients -- who have so little control over a disease like leukemia -- feel empowered if they at least have control over their food.

Sekeres said he found the study "validating" and suggested that "we should eliminate these silly neutropenic diets and let people eat what they want and give them a much better quality of life when they're in the hospital."

Scientists finally know why people get more colds and flu in winter

The tripledemic is here – worst flu numbers in a decade, RSV in kids never exposed before and, oh yeah, there’s COVID.  So, what’s a person to do?  Some will hibernate as they did recent winters, others will have to get out, whether they like it or not.  The MASK thing is rearing it’s ugly head again.  But is there any real reason to use them?  That continues to be hotly debated in many areas, and I think that if you’re in a tight indoor space for some period of time (not a really long time because whatever’s in the air will eventually make it in) mask wearing is hard to argue against.  Now there’s a study that speaks to WHY it might make a difference in the winter, and it has nothing to do with the particular bug that’s floating around.  While there are limitations to this conclusion, it might just make enough sense to follow.

FROM CNN / BY SANDEE LAMOTTE

A chill is in the air, and you all know what that means — it’s time for cold and flu season, when it seems everyone you know is suddenly sneezing, sniffling or worse. It’s almost as if those pesky cold and flu germs whirl in with the first blast of winter weather.

Yet germs are present year-round — just think back to your last summer cold. So why do people get more colds, flu and now Covid-19 when it’s chilly outside?

In what researchers are calling a scientific breakthrough, scientists behind a new study may have found the biological reason we get more respiratory illnesses in winter. It turns out the cold air itself damages the immune response occurring in the nose.

“This is the first time that we have a biologic, molecular explanation regarding one factor of our innate immune response that appears to be limited by colder temperatures,” said rhinologist Dr. Zara Patel, a professor of otolaryngology and head and neck surgery at Stanford University School of Medicine in California. She was not involved in the new study.

In fact, reducing the temperature inside the nose by as little as 9 degrees Fahrenheit (5 degrees Celsius) kills nearly 50% of the billions of virus and bacteria-fighting cells in the nostrils, according to the study published Tuesday in The Journal of Allergy and Clinical Immunology.

“Cold air is associated with increased viral infection because you’ve essentially lost half of your immunity just by that small drop in temperature,” said rhinologist Dr. Benjamin Bleier, director of otolaryngology translational research at Massachusetts Eye and Ear and an associate professor at Harvard Medical School in Boston.

“it’s important to remember that these are in vitro studies, meaning that although it is using human tissue in the lab to study this immune response, it is not a study being carried out inside someone’s actual nose,” Patel said in an email. “Often the findings of in vitro studies are confirmed in vivo, but not always.”

A hornet’s nest

To understand why this occurs, Bleier and his team and coauthor Mansoor Amiji, who chairs the department of pharmaceutical sciences at Northeastern University in Boston, went on a scientific detective hunt.

A respiratory virus or bacteria invades the nose, the main point of entry into the body. Immediately, the front of the nose detects the germ, well before the back of the nose is aware of the intruder, the team discovered.

At that point, cells lining the nose immediately begin creating billions of simple copies of themselves called extracellular vesicles, or EV’s.

“EV’s can’t divide like cells can, but they are like little mini versions of cells specifically designed to go and kill these viruses,” Bleier said. “EV’s act as decoys, so now when you inhale a virus, the virus sticks to these decoys instead of sticking to the cells.”

Those “Mini Me’s” are then expelled by the cells into nasal mucus (yes, snot), where they stop invading germs before they can get to their destinations and multiply.

“This is one of, if not the only part of the immune system that leaves your body to go fight the bacteria and viruses before they actually get into your body,” Bleier said.

Once created and dispersed out into nasal secretions, the billions of EV’s then start to swarm the marauding germs, Bleier said.

“It’s like if you kick a hornet’s nest, what happens? You might see a few hornets flying around, but when you kick it, all of them all fly out of the nest to attack before that animal can get into the nest itself,” he said. “That’s the way the body mops up these inhaled viruses so they can never get into the cell in the first place.”

A big increase in immune power

When under attack, the nose increases production of extracellular vesicles by 160%, the study found. There were additional differences: EV’s had many more receptors on their surface than original cells, thus boosting the virus-stopping ability of the billions of extracellular vesicles in the nose.

“Just imagine receptors as little arms that are sticking out, trying to grab on to the viral particles as you breathe them in,” Bleier said. “And we found each vesicle has up to 20 times more receptors on the surface, making them super sticky.”

Cells in the body also contain a viral killer called micro RNA, which attack invading germs. Yet EVs in the nose contained 13 times micro RNA sequences than normal cells, the study found.

So the nose comes to battle armed with some extra superpowers. But what happens to those advantages when cold weather hits?

To find out, Bleier and his team exposed four study participants to 15 minutes of 40-degree-Fahrenheit (4.4-degree-Celsius) temperatures, and then measured conditions inside their nasal cavities.

“What we found is that when you’re exposed to cold air, the temperature in your nose can drop by as much as 9 degrees Fahrenheit. And that’s enough to essentially knock out all three of those immune advantages that the nose has,” Bleier said.

In fact, that little bit of coldness in the tip of the nose was enough to take nearly 42% of the extracellular vesicles out of the fight, Bleier said.

“Similarly, you have almost half the amount of those killer micro RNA’s inside each vesicle, and you can have up to a 70% drop in the number of receptors on each vesicle, making them much less sticky,” he said.

What does that do to your ability to fight off colds, flu and Covid-19? It cuts your immune system’s ability to fight off respiratory infections by half, Bleier said.

You don’t have to wear a nose sock

As it turns out, the pandemic gave us exactly what we need to help fight off chilly air and keep our immunity high, Bleier said.

Wearing a mask can protect you from cold air that can reduce your immunity, an expert says.

“Not only do masks prrhinologist Dr. Benjamin Bleierotect you from the direct inhalation of viruses, but it’s also like wearing a sweater on your nose,” he said.

Patel agreed: “The warmer you can keep the intranasal environment, the better this innate immune defense mechanism will be able to work. Maybe yet another reason to wear masks!”

In the future, Bleier expects to see the development of topical nasal medications that build upon this scientific revelation. These new pharmaceuticals will “essentially fool the nose into thinking it has just seen a virus,” he said.

“By having that exposure, you’ll have all these extra hornets flying around in your mucous protecting you,” he added.
