Combined effects of masking and distance on aerosol exposure potential

The Centers for Disease Control and Prevention (CDC) recommended this week that people vaccinated against COVID-19 resume wearing masks in public indoor spaces in areas of the United States where the virus is spreading. “Appropriate masking in addition to vaccination remain the best methods to help protect individuals from the Coronavirus,” says Gregory Poland, M.D., an infectious disease expert at Mayo Clinic.

20-year Mayo Clinic study suggests return to play is manageable for athletes with most genetic heart diseases

Receiving the diagnosis of a genetic heart disease such as long QT syndrome, which can cause sudden cardiac death, has long been a game-ender for young athletes. But a 20-year study at Mayo Clinic following such athletes who were allowed to return to play suggests that the risks can be managed through a shared decision-making process. The retrospective study findings will be presented at the annual meeting of the Heart Rhythm Society on Tuesday, July 27, and simultaneously published in the Journal of the American College of Cardiology.

A new study by Fergus Couch, Ph.D., of Mayo Clinic Cancer Center, along with collaborators from the CARRIERS consortium, suggests that most women with breast cancer diagnosed over 65 should be offered hereditary cancer genetic testing. The study was published Thursday, July 22, in the Journal of Clinical Oncology.

Monoclonal antibodies help COVID-19 patients avoid hospitalization

In a large observational study, Mayo Clinic researchers have shown that two monoclonal antibodies administered separately helped prevent hospitalization in high-risk patients who became infected with COVID-19. The study also showed more hospitalizations were observed among patients with more comorbidities. The findings appear in The Journal of Infectious Diseases.

Strong immune response underlies acute kidney injury related to COVID-19

Mayo Clinic researchers have found that acute kidney injury associated with COVID-19 resembles sepsis-caused kidney injury, and the immune response triggered by the infection plays a pivotal role.

The findings, published in Mayo Clinic Proceedings, also suggest that mitochondrial dysfunction — a loss of function in cellular energy production — is commonly found in kidney injury related to COVID-19.

Mayo research provides insights into high-risk younger demographics for severe COVID-19

Using data from 9,859 COVID-19 infections, Mayo Clinic researchers have new insights into risk factors for younger populations, some of which differ significantly from their older counterparts. People younger than 45 had a greater than threefold increased risk of severe infection if they had cancer or heart disease, or blood, neurologic or endocrine disorders, the research found. These associations were weaker in older age groups. The study was published in Mayo Clinic Proceedings.

Study may show why MS patients develop progressive disability but those with related diseases do not

Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not.

In a study published in Neurology, Mayo Clinic researchers and colleagues assessed if inflammation leads to permanent scarring in these three diseases:

Monoclonal antibody therapy for COVID-19 safe, effective for transplant patients

Treating transplant patients with mild to moderate cases of COVID-19 with monoclonal antibodies is safe and helps prevent serious illness, according to a Mayo Clinic study recently published in Open Forum Infectious Diseases. These results are especially important because transplant patients who are infected with COVID-19 have a higher risk of severe illness and death.

Senolytics reduce COVID-19 symptoms in preclinical studies

Mayo Clinic researchers and colleagues at the University of Minnesota showed that COVID-19 exacerbates the damaging impact of senescent cells in the body. In preclinical studies, the senolytic drugs discovered at Mayo significantly reduced inflammation, illness, and mortality from COVID infection in older mice. The findings appear in the journal Science.

Remote patient monitoring may reduce need to hospitalize cancer patients

ROCHESTER, Minn. — A study by researchers at Mayo Clinic Cancer Center has found that cancer patients diagnosed with COVID-19 who received care at home via remote patient monitoring were significantly less likely to require hospitalization for their illness, compared to cancer patients with COVID-19 who did not participate in the program. Results of the study were presented Friday, June 4, at the American Society of Clinical Oncology Annual Meeting and published in the Journal of Clinical Oncology.

Mayo Clinic preclinical discovery triggers wound healing, skin regeneration

Difficult-to-treat, chronic wounds in preclinical models healed with normal scar-free skin after treatment with an acellular product discovered at Mayo Clinic. Derived from platelets, the purified exosomal product, known as PEP, was used to deliver healing messages into cells of preclinical animal models of ischemic wounds. The Mayo Clinic research team documented restoration of skin integrity, hair follicles, sweat glands, skin oils and normal hydration.

Ischemic wounds occur when arteries are clogged or blocked, preventing important nutrients and oxygen from reaching the skin to drive repair. This groundbreaking study titled, “TGF-β Donor Exosome Accelerates Ischemic Wound Healing,” is published in Theranostics.

Lack of diversity in genomic databases may affect therapy selection for minority groups

Low representation of minority groups in public genomic databases may affect therapy selection for Black patients with cancer, according to new Mayo Clinic research published in npj Precision Oncology.

The researchers investigated the use of genomic databases and found that tumor mutation burden was significantly inflated in Black patients compared to White patients.

As a result of the study, clinicians who are using public genomic databases need to be aware of the potential for inflated tumor mutation burden values and how that may affect therapy selection and outcomes, especially for patients from underrepresented groups.

Genetic testing proves beneficial in prescribing effective blood thinners

A new research paper funded in part by the National Heart, Lung and Blood Institute (NHLBI) shows a clear advantage of genetic testing in helping health care providers choose the appropriate anti-platelet drug. Testing helps determine if a patient carries genetic variants in CYP2C19 that cause loss of its function. These variants interfere with the body’s ability to metabolize and activate clopidogrel, an anti-platelet medication.
