Welcome to Advancing the Science.

On Mayo Clinic’s medical research blog we have a wide range of research and research-education content. In addition to stories you won’t find anywhere else, we also collect content from other sources in one easy-to-access spot.

The monthly Research News Roundup is one such aggregator, highlighting and linking to all the research news releases from the previous month. Enjoy, and come back again.

Rose Geranium Lavender herb species as well as coconut and sugar RoseRose geranium oil may help to ease the symptoms of nasal vestibulitis, a common and painful nasal condition linked to cancer drug treatment, according to the results of a small observational study, published online in the journal BMJ Supportive & Palliative Care

“Nasal vestibulitis is a side effect of cancer drug treatment, and is particularly common in people treated with a class of drugs called taxanes,” says lead author Elizabeth Cathcart-Rake, M.D., a Hematology Oncology resident at Mayo Clinic. These drugs stop cell division and stunt the formation of new blood vessels to prevent tumor growth.” Dr. Cathcart-Rake says there are no treatments currently available for this unpleasant side effect of cancer therapy.

On a related note, Mayo Clinic’s Integrative Medicine and Health team helps people use health and wellness practices for physical, emotional, mental and spiritual well-being. Integrative therapies complement rather than replace conventional Western medical care. These integrative practices — sometimes called complementary and alternative medicine — may help people with cancer, persistent pain, chronic fatigue, fibromyalgia and many other conditions.

These findings were presented on Tuesday, Oct. 23, by Mayo Clinic researchers at the 2018 annual meeting of the American Society for Radiation Oncology (ASTRO) in San Antonio.


Researchers at Mayo Clinic have identified three specific gene types that account for a known two-to-three-fold increase in myeloma diagnoses among African-Americans. Researchers also demonstrated the ability to study race and racial admixture more accurately using DNA analysis. The findings were published today in Blood Cancer Journal.

“Myeloma is a serious blood cancer that occurs two to three times more often in African-Americans than Caucasians,” says Vincent Rajkumar, M.D., a hematologist at Mayo Clinic and senior author of the study. “We sought to identify the mechanisms of this health disparity to help us better understand why myeloma occurs in the first place and provide insight into the best forms of therapy.”


An international team of researchers led by Konstantinos Lazaridis, M.D., a Mayo Clinic gastroenterologist, has developed a new tool to help predict outcomes of primary sclerosing cholangitis. The team’s work is published in Hepatology.

Primary sclerosing cholangitis is a disease of the bile ducts, in which persistent inflammation causes scarring, hardening and narrowing of the ducts that eventually may lead to serious liver damage. The disease is commonly associated with inflammatory bowel disease and, usually, ulcerative colitis.


Mayo Clinic announced on Monday, Oct. 8, that it received a $10 million grant from The Louis V. Gerstner Jr. Fund at Vanguard Charitable on the recommendation of Louis V. and Robin L. Gerstner.

The grant will support five initiatives across Mayo Clinic’s Arizona, Florida and Minnesota sites, and continues a long relationship with Mayo Clinic that includes the Gerstner Family Career Development Awards in Mayo Clinic’s Center for Individualized Medicine.

The grant advances research in the use of augmented human intelligence in cardiovascular care, and advances care for arthritis and spine pain using regenerative medicine and data analytics. Also, the grant provides specialized education opportunities for nurse practitioners and physician assistants.


Mayo Clinic researchers have identified the drug estradiol as a potential new treatment for a subset of women with triple-negative breast cancer. Their findings are published in the Proceedings of the National Academy of Sciences of the United States of America.

“Triple-negative breast cancer is a form of breast cancer that lacks expression of estrogen receptor alpha, progesterone receptor, and human epidermal growth factor receptor 2, also known as HER2. And it exhibits high rates of disease recurrence,” says John Hawse, Ph.D., a molecular biologist at Mayo Clinic and senior author. “So far, there have been few drugs other than chemotherapy that appear to work effectively for the treatment of this disease.”


Obese patients who underwent a life-saving liver transplant and weight-loss surgery at the same time were better able to keep the weight off long term and had fewer metabolic complications than those who lost weight on their own before undergoing a liver transplant, Mayo Clinic research shows. The findings were recently published in Hepatology.

“This study shows that the combined approach of liver transplantation and weight-loss surgery is safe and effective over the long term,” says senior author Julie Heimbach, M.D., a transplant surgeon and division chair of Transplant Surgery at Mayo Clinic.

As obesity rates in the U.S. have soared, so have the number of people diagnosed with nonalcoholic fatty liver disease – a range of liver diseases that affects people who drink little to no alcohol and results in too much fat stored in liver cells.


Researchers at Mayo Clinic have developed a new genetics-based prognostic tool for myelodysplastic syndrome. Their findings are published in the October print issue of Mayo Clinic Proceedings.

“Myelodysplastic syndrome is one of the most frequent blood cancers affecting the elderly with annual incidence exceeding 50 cases per 100,000 in people 65 years or older,” says Ayalew Tefferi, M.D., a Mayo Clinic hematologist who is the principal investigator and lead author.

Dr. Tefferi says the average survival for patients with myelodysplastic syndrome is estimated at 2½ years, and survival rates have not improved over the past several decades.  Read more.

Each month, we publish Mayo Clinic’s Research News Roundup. This article includes brief summaries and links to news releases from the preceding month that discuss some of our latest medical research. It also connects readers to related resources.

Read on for recent findings of Mayo Clinic Research:

human body anatomy with the liver highlightedA team of researchers from Mayo Clinic Cancer Center has been awarded a five-year, $11.5-million Specialized Program of Research Excellence (SPORE) grant in liver and biliary tract cancer from the National Cancer Institute (NCI).

Specialized Program of Research Excellence grants are designed to promote interdisciplinary research and help basic research findings move quickly from the laboratory to patient care.

To earn these competitive grants, institutions must demonstrate a high degree of collaboration between top scientists and clinicians and show excellence in translational research projects.


The medical community has long known that patients on long-term opioid therapy often have significantly more health care visits. But adhering to a standardized care process model for opioid prescriptions appears to reduce the overall number of health care visits for these patients while maintaining safety, shows new research published in Mayo Clinic Proceedings.

Controlled substance agreements outline an individualized pain care plan for patients ─ in this case for those needing ongoing opioid therapy.


a portrait of a smiling middle-aged woman, seated, with her chin resting on her handPremenopausal women who have their ovaries surgically removed face an increased risk of developing chronic kidney disease, according to a Mayo Clinic study published on Wednesday, Sept. 19, in the Clinical Journal of the American Society of Nephrology.

“This is the first study that has shown an important link between estrogen deprivation in younger women and kidney damage. Women who have their ovaries surgically removed have an increased long-term risk of chronic kidney disease,” says Walter Rocca, M.D., a Mayo Clinic neurologist and epidemiologist, and senior author.

The research team used data from the Rochester Epidemiology Project to determine these findings.


Zombie cells are the ones that can’t die but are equally unable to perform the functions of a normal cell. These zombie, or senescent, cells are implicated in a number of age-related diseases. And with a new letter in Nature, Mayo Clinic researchers have expanded that list.

In a mouse model of brain disease, scientists report that senescent cells accumulate in certain brain cells prior to cognitive loss. By preventing the accumulation of these cells, they were able to diminish tau protein aggregation, neuronal death and memory loss.


Resident physician burnout in the U.S. is widespread, with the highest rates concentrated in certain specialties, according to research from Mayo Clinic, Oregon Health & Science University and collaborators. The findings appeared on Tuesday, Sept. 18, in the Journal of the American Medical Association. Physician burnout is a dangerous mix of exhaustion and depersonalization that contributes to physicians making mistakes while administering health care.


 

Mayo Clinic physicians Matthew Block, M.D., Ph.D. and Tina Hieken, M.D., have received a Stand up to Cancer (SU2C) Catalyst Award to fund melanoma research and a neoadjuvant clinical trial.

“This study, “Neoactivate”, will test two novel approaches to the treatment of patients with high-risk, stage 3 melanoma guided by specific mutations within the melanoma,” says Dr. Hieken. “Two combinations of immunotherapy and targeted therapy will be given before surgery, and all patients will receive immunotherapy after surgery.”

Thu, Sep 27 6:00am · Research helps play it safe in the ICU

ICU use of PTZ/VAN combo therapy safe for kidneys

Life threatening infections, or sepsis, are one of the most common reasons people end up in the intensive care unit or stay longer in the hospital than originally expected. To combat these infections, physicians can choose from several antibiotics, and often will use a combination of drugs until they are certain of what is causing the infection. However, as with every drug, there are risks. Antibiotics are no exception to this rule, making the choice a difficult one. On one hand, physicians need to treat the serious infection, but on the other hand, risks such as life-threatening kidney damage can occur with some of these drugs.

Recently, Mayo Clinic pharmacy resident Diana Schreier, Pharm.D., R.Ph.; led  a research study to determine the safety of one particular combination of antibiotics for short-term use in the ICU. Published in Clinical Infectious Diseases, the team’s research shows that short-term use of the combination of piperacillin/tazobactam and vancomycin (PTZ/VAN) is no more toxic to the kidneys than other combinations.

This is an important finding, because prior to this research, small studies, mostly in non-ICU patients, indicated that PTZ/VAN can injure kidneys when used over a long period. Learning this, some ICU physicians stopped using this combination, and instead substituted other combinations that have their own risks, including toxicity to the brain or high potential to promote the development of resistant superbugs.

It was after noticing these shifts in practice that Dr. Schreier worried that misapplying these previous studies to broad use in the ICU could lead to loss of this important medication combination in the arsenal for clinicians.

“No one had previously looked at the kidney risk of these short-term treatments with combination PTZ/VAN in a rigorous way,” says Dr. Schreier. “We were seeing this practice shift, but without good evidence of how it applied to our sick ICU patients. We wanted to preserve these essential antibiotic combinations and give clinicians more confidence about the risks and benefits of the choices available to them.”

ICU patients often will receive more than one antibiotic, in an attempt to curb infection while waiting on cultures for a definitive cause.

Over the years, because of widespread antibiotic use and even overuse, organisms have developed resistance to various antibiotics. Both the source of infection and level of resistance can vary between individuals and hospitals, so choosing the right combination of antibiotics becomes something of an art form for physicians.

Dr. Schreier and her colleagues hoped to ease concerns about the PTZ/VAN combination, allowing for continued use of this set of tools in critically ill patients.

“Usually combination therapy is started because we are unsure what organism is causing the patient’s infection,” she says. “In these cases, we are providing two or more antibiotics that cover a wide range of bugs that could be causing the infection. This allows us to treat the patient broadly while we wait for cultures to return and give us the definite cause.”

“The more tools we have in the toolbox in these situations, the better off our patients will be,” she says, “and with antibiotics, this is especially true. PTZ is very effective and covers many types of infections.  Loss of it as a treatment would leave a huge hole that new drugs have yet to fill.”

During their research, the team looked at medical records for 3,299 ICU patients who received 24- to 72-hours of different commonly-used antibiotic combinations including vancomycin (VAN treats resistant staph infections) with piperacillin/tazobactam (PTZ/VAN), cefepime (CEF/VAN), or meropenem (MER/VAN). Overall, about 9 percent of the patients suffered moderate to severe kidney damage which did not differ between the antibiotics selected even after accounting for the many contributors to kidney damage in sick ICU patients. Further, the antibiotic combination chosen did not affect long-term kidney damage.

Because of this research, doctors can continue to rely on this long-used tool as one of the antibiotic options for patients, says Dr. Schreier.

“We are pleased to have been able to show that PTZ/VAN can remain viable for ICU care,” she says. “These new data are reassuring and highlight how important it is to perform large studies in specific high-risk groups before broadly applying information to everyone.”

She and her colleagues plan to continue to look for ways to expand understanding of which drugs work for what conditions, how they work, and ways to make them work better.

Thu, Sep 13 6:00am · The rising tide of nonalcoholic fatty liver disease

Liver disease? Me? I don’t drink. I don’t smoke. Okay, so I don’t exercise that much, and where did all these candy bar wrappers come from?

Anyway, I thought liver disease was just for alcoholics?

These are question many Americans ask when diagnosed with nonalcoholic fatty liver disease. But as its name implies, NAFLD is an umbrella term for a range of liver conditions in people who drink little or no alcohol. In NAFLD, excess fat is stored in the liver, and can lead to inflammation, scarring and potentially liver failure.

NAFLD is a significant and growing public health issue, but until now, we didn’t have a good handle on just how big this wave has grown.

Recently, Alina Allen, M.D., a gastroenterologist and population health researcher at Mayo Clinic, and colleagues, published a paper describing the incidence, as well as the life and death implications of this type of liver disease.

The researchers used the Rochester Epidemiology Project, a collaboration of clinics, hospitals, and other medical and dental facilities in Minnesota and Wisconsin that links together the medical and the dental records for people who have agreed to share their health history for the purpose of research.

The team showed that five times as many people have this type of liver disease now, as compared to 1997.

Alina Allen, M.D.

“This finding was not that surprising,” says Dr. Allen. “NAFLD is a consequence of obesity, and over the last few decades, we’ve observed a steadily rising rate of overweight people.”

She clarifies that improvements in imaging technology and increased awareness among providers may have contributed some to the increased numbers. Regardless, the team discovered that community-wide, people with NAFLD had a significantly higher risk of dying within 10 years of diagnosis, than others without NAFLD.

Dr. Allen also noted:

  • NAFLD contributes to the likely development of other diseases such as diabetes, hypertension and out of whack blood fat levels (cholesterol and triglycerides) called dyslipidemia – all known to hasten death, on their own.
  • But just NAFLD alone doubles the risk of death, and risk of cardiovascular events (for example, a heart attack).

NAFLD reduces life expectancy by about four years, which could cause us to miss a whole lot of moments with loved ones. While we may not be able to prevent the oceans from rising or falling, we can turn this tide.

“The key is maintaining a healthy weight,” Dr. Allen says, “or, for those who are overweight or obese, losing weight before the liver disease advances to cirrhosis.”

“The good news,” she says, “is that we know weight loss can reverse the unwanted consequences in the liver, such as fat, inflammation and even scar tissue. Additionally, adequate control of diabetes, hypertension and dyslipidemia have beneficial impacts on liver disease.”

Weight loss would help with those other conditions too, she notes.

If decreased health and lower life expectancy aren’t alarming enough to stop the rising tide of NAFLD cases, maybe knowing the dollars will. Dr. Allen and her colleagues also looked at the financial burden of this disease. In a related study, using the OptumLabs Data Warehouse, they showed that health care costs for patients diagnosed with NAFLD are significant – regardless of whether they have other metabolic conditions such as diabetes.

The team compared costs for more than 108,000 patients diagnosed with NAFLD, between 2010 – 2014, with those for similar patients lacking only the NAFLD diagnosis. The first years’ care added an average of $7,804 in health care costs; with follow-on care averaging $3,789 additional per year.

This garnered some attention in the news, and Dr. Allen hopes that both of these studies will contribute to patient and family awareness. They offer opportunities for life-changing conversations with health care providers, and may lead to more research to further transform health and the experience of health care. And above all, they may help stem the tide of NAFLD.

This research was made possible by the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery. The OptumLabs Data Warehouse contains deidentified administrative claims data, including medical claims and eligibility information from a large national U.S. health insurance plan, as well as electronic health record data from a nationwide network of provider groups.

Researchers at Mayo Clinic have identified an important new pathway by which HER2 positive breast cancers grow and have discovered that a dietary supplement called cyclocreatine may block the growth of HER2 positive breast cancer. Their findings were published today in Cell Metabolism.

Taro Hitosugi, Ph.D., a pharmacologist at Mayo Clinic, and his colleagues were hoping to find a way to help patients with HER2 positive breast cancer, in whom their cancer is or may become resistant to the typical therapy – trastuzumab. Their strategy was to develop a treatment to target tumor mitochondrial energy metabolism, which is the process cancer cells use to manipulate energy during cell metabolism in order to grow.

The use of mud or wet clay as a topical skin treatment or a poultice is a common practice in some cultures and the concept of using mud as medicine goes back to earliest times. Now Mayo Clinic researchers and their collaborators at Arizona State University have found that at least one type of clay may help fight disease-causing bacteria in wounds, including some treatment-resistant bacteria.

The findings appear in the International Journal of Antimicrobial Agents.

 

A research team led by Fergus Couch, Ph.D., a geneticist at Mayo Clinic, has identified specific genes associated with an increased risk for developing triple-negative breast cancer. Their research was published in the Journal of the National Cancer Institute.

“Triple-negative breast cancer is an aggressive type of cancer that cannot be treated using targeted therapies,” says Dr. Couch. “It accounts for 15 percent of breast cancer in the Caucasian population and 35 percent in the African-American population. It is also associated with a high risk of recurrence and a poor five-year survival rate. Our findings provide the basis for better risk management.”

Read more about their research findings.

Despite increased attention to opioid abuse, prescriptions have remained relatively unchanged for many U.S. patients, research led by Mayo Clinic finds. The research, published in The BMJ, shows that opioid prescription rates have remained flat for commercially insured patients over the past decade. Rates for some Medicare patients are leveling but remain above where they were 10 years ago.

“Our data suggest not much has changed in prescription opioid use since about five years ago,” says Molly Jeffery, Ph.D., lead author, who is the scientific director of the Mayo Clinic Division of Emergency Medicine Research.

Read the full news release.

A preliminary study published in the August issue of Mayo Clinic Proceedings suggests that, for some people, specific activities of gut bacteria may be responsible for their inability to lose weight, despite adherence to strict diet and exercise regimens.

“We know that some people don’t lose weight as effectively as others, despite reducing caloric consumption and increasing physical activity,” says Purna Kashyap, M.B.B.S., a Mayo Clinic gastroenterologist and co-senior author of the study. Dr. Kashyap and his colleagues wondered if there may be other factors at work that prevented these patients from responding to traditional weight-loss strategies.

Read about their findings.

Astronauts intermittently monitor their vital signs in space for experiments, partly because continuous monitoring requires multiple contact points on the body and the use of cumbersome batteries. Now, researchers at Mayo Clinic’s Florida campus are studying a device to be launched into space that is designed to use a small, inexpensive camera fitted with specialized software. This software has the potential to monitor an astronaut’s vital signs continuously and contact-free from feet away, saving precious cargo space and leaving astronauts unencumbered.

A married couple, both of who are physician-researchers at Mayo Clinic, are partnering on this project.

William D. Freeman, M.D., and Michelle Freeman, M.D., discuss the monitoring project.

Thu, Aug 30 6:00am · Knock, knock, the nurse practitioner is here

Burt and Ardis Ramaker were pleased with their experience in the Care Transitions Program, and thankful it helped Burt to recover at home.

When Burt Ramaker left the hospital following a successful hip replacement, he didn’t plan to go back any time soon. He and his wife Ardis imagined they would spend time at a skilled nursing facility to get him back on his feet, and then they’d be back at their waterfront cabin.

Instead, they found themselves in and out of the doctor’s office and the emergency room. Burt was on his way to being readmitted to the hospital. Patients of all ages with multiple chronic conditions are more likely than others to be readmitted to the hospital soon after discharge. However, this risk is especially high for older patients like Burt, especially if they have several chronic health conditions.

But if patients receive the right care, at the right time, and the right place, many of these readmissions could be prevented. And that was why Burt was identified for the program and his doctor recommended Burt sign up for a care management effort called the Care Transitions Program.

Newfangled house calls

At the Rochester, Minnesota, campus, the Care Transitions Program, part of Mayo Clinic’s Department of Employee and Community Health, features a new kind of house call. The program offers services to older adults with complex medical needs when they leave the hospital or skilled nursing facility. The patient-centric program features a home visit from a nurse practitioner within five days of discharge. In addition, patients receive follow-up phone calls from their care team, access to a nurse line for urgent questions or concerns, and additional house calls by the nurse practitioner when necessary.

Supervised by geriatricians – physicians specializing in elder care – the program provides individualized care and support for patients and their families.

Brenda Danielson is an advanced practice registered nurse and certified nurse practitioner at Mayo Clinic in Rochester, Minnesota.

Shortly after Burt enrolled, he and Ardis were visited by Brenda Danielson, a nurse practitioner in the program. She examined Burt, and they sat down to discuss what to do about his newly diagnosed heart failure and severe fluid build-up. Danielson wrote notes for Ardis and Burt, detailing his care plan and what had been discussed.

The Ramakers say Danielson visited monthly for several months – replacing what had been approximately weekly visits to the clinic or emergency room.

“It was great,” says Burt. “It saved me going up to the hospital a number of times, and I thought she [Danielson] was great!” He was unhappy at the nursing facility, he says, and “this program allowed me to come home.”

Danielson and others like her work with patients in the program to provide:

  • Medication reconciliation – both reducing use of high-risk medications, and lessening medication ‘misadventures’
  • Home safety assessments
  • Community resource referrals
  • Continued care for the health problem that led to the patient’s hospitalization, as well as the patient’s chronic health conditions

Burt Ramaker credits the Care Transitions Program as the reason he can step out onto his patio and fill the bird feeder, and engage in a host of other life activities.

The nurse practitioners also work with the patient to determine his or her goals for care, as well as to determine sources of social and other types of support. Together they develop strategies for:

  • Early recognition and management of health issues (before they necessitate an emergency department visit and potential readmission)
  • Patient self-management of chronic diseases
  • Advanced care planning

In Burt and Ardis’s case, Danielson also helped Ardis to understand and fill out insurance paperwork.

“I felt so comfortable asking for help,” says Ardis, “[for] any questions I had.”

Ardis says having the nurse practitioner visit, talk with them and leave detailed notes, helped her. “Knowing that I was doing it right,” she says was a comfort. And Burt got better – which they both say was their biggest benefit.

Patients like them, but do these house calls have other value?

“Bringing care to the patient is not only patient-centered, but can be beneficial to the institution,” says Rozalina McCoy, M.D., a primary care physician at Mayo Clinic who is also part of the Care Transitions Program team. But what seems like a good idea needs to be proven to add value. So the physician-researchers put it to the test.

They report that the program nearly halves unplanned readmissions within 30 days of discharge. Their research also shows better quality of life, fewer visits to the emergency department, decreased risk of death, and other potential benefits, including lower overall care costs for individuals and the health care system.

However, these observations have been broad, and the team is digging in further, to determine ways to predict and prevent readmission for as many people as possible. In addition, some types of readmission really aren’t preventable. Understanding these nuances will help Mayo Clinic provide better care for patients, and further refine the Care Transitions Program and other programs like it.

The latest piece of evidence

Patients enrolled in the program were much less likely to be readmitted than patients receiving usual care.

In their most recent study, led by Dr. McCoy, the researchers examined the program to determine its ability to reduce potentially preventable and non-preventable 30-day readmissions.

Using both a commercially available algorithm and another from the Centers for Medicare and Medicaid Services, Dr. McCoy’s team first determined which readmissions were potentially preventable. Some readmissions, she says, are either planned, or impossible to avoid, regardless of intervention.

Their study group included 365 enrollees in the Mayo Clinic Care Transitions Program, matched to a control group of patients who met enrollment criteria for, but were not enrolled, in the program.

In addition to being a primary care physician, Rozalina McCoy, M.D., is an endocrinologist, and conducts health sciences research at Mayo Clinic.

Overall, they report, patients enrolled in the program were much less likely to be readmitted than patients receiving usual care. However, when examining reasons for readmission, the team found that about two-thirds of all readmissions may still be preventable, both among patients enrolled in the Care Transitions Program and among those not enrolled. So even though the Care Transitions Program prevented more than 4 out of 10 readmissions, there is still a lot of room for further research into specific interventions for program participants.

In addition, readmissions for all causes – not just those related to the reason for the patients’ first hospital stay – seemed to be prevented, suggesting that providing intensive home-based care to high-risk patients may be an effective strategy in general, not just after a hospital admission.

“We believe timely home visits and a coordinated care program can prevent all types of hospitalizations, ED [emergency department] visits, and hospital readmissions,” says Dr. McCoy. “Perhaps not ‘all’ hospitalizations and readmissions, but certainly as we refine our ability to identify patients who are likely to have events or poor health outcomes, and then provide intensive, individualized, home-based transitional care, we expect the numbers to continue to decrease.”

Decreasing hospitalizations is great, of course, for patients and health care in general. But on an individual level, for Burt and Ardis, it means more time together, and more time fishing at the cabin.

In adults over 70, exposure to general anesthesia and surgery is associated with a subtle decline in memory and thinking skills, according to new Mayo Clinic research. The study analyzed nearly 2,000 participants in the Mayo Clinic Study of Aging and found that exposure to anesthesia after age 70 was linked to long-term changes in brain function. The results appear in the British Journal of Anaesthesia.

Golfers’ lapses in play sometimes are blamed on a mysterious twitching condition called “the yips.” But are yips physical or psychological? In a new Mayo Clinic study, published this month in Medicine & Science in Sports & Exercise, researchers combined multiple methods to quantify golfers’ yips and identify those with a neurological cause.
