All Age-Related Changes May Not Be Inevitable: Senescent Cells and Anti-Aging

Guest: Nathan K. LeBrasseur, Ph.D., M.S. (@NKLeBRASSEUR) Host: Darryl S. Chutka, M.D. (@ChutkaMD) The effects of aging occur in all our organs. In muscles, there is a reduction in strength and stamina; the brain shows a decrease in cognitive function and the ability to learn new information. Aging causes a reduced ability of the liver to metabolize drugs and the kidney’s ability to eliminate various waste products. Our guest for this podcast is aging researcher Nathan K. LeBrasseur, Ph.D., M.S., the senior author of a study recently published in the journal “Aging Cell.” The authors described significant benefits from exercise on a cellular level which correlated with an improvement in physical changes related to aging. We’ll discuss cellular changes which occur with aging, the significance of senescent cells and how exercise can reduce the impact of aging on both a cellular level as well as clinically. Specific topics: The effects of aging on a cellular level Variability in the rate of aging in individuals Function of senescent cells Effects of exercise on senescent cells Clinical correlations resulting from the elimination of senescent cells Recommendations clinicians can give their patients to reduce the effects of aging

Mayo Clinic Q&A: January Bringing an Omicron Surge

This episode is shared from Mayo Clinic Q&A and was recorded in January 2022 Guest: Gregory A. Poland, M.D. (@drgregpoland) Host: Halena M. Gazelka, M.D. (@hmgazelkamd) The rapid spread of COVID-19 due to the omicron variant continues, and experts expect a January surge across the U.S.  "This is spreading unlike anything we've seen in the U.S.," says Dr. Gregory Poland, head of Mayo Clinic's Vaccine Research Group.  "Over the last seven days, we're now averaging about 400,000 or so new cases a day." While people who are fully vaccinated can get breakthrough infections and spread the virus to others, COVID-19 vaccines effectively prevent severe illness. Mayo Clinic experts urge people to protect themselves by getting vaccinated and wearing a mask. Being fully vaccinated, including getting a booster when eligible, offers the highest protection possible against COVID-19.  "The good news is, for those who are immunized and boosted, we are winning the battle," says Dr. Poland. "Getting immunized is basically a weapon against this virus." On the Mayo Clinic Q&A podcast, Dr. Poland discusses the omicron surge and the importance of vaccines and boosters for COVID-19.

Temporal Arteritis

Guest: Andy Abril, M.D. (@andyabrilMD) Host: Darryl S. Chutka, M.D. (@ChutkaMD) Temporal arteritis is a vasculitis involving medium-sized vessels and typically occurs in those over the age of 50. If diagnosed and treated early, there is an excellent likelihood of recovery. However, temporal arteritis often mimics other health problems and this commonly results in a delay in the diagnosis. If untreated, serious complications can occur, including permanent blindness or stroke. The topic for this podcast is temporal arteritis and our guest is Andy Abril, M.D., Chair of the Division of Rheumatology at the Mayo Clinic in Jacksonville, Florida. We’ll discuss the risk factors, presenting symptoms and complications of temporal arteritis, as well as the recommendations for establishing a diagnosis and initiating appropriate treatment. Specific topics discussed: Risk factors for temporal arteritis Presenting symptoms Complications of untreated temporal arteritis Extra-cranial artery involvement of patients with temporal arteritis Relationship of temporal arteritis and polymyalgia rheumatica Laboratory abnormalities in temporal arteritis Importance of an early temporal artery biopsy in establishing a diagnosis Treatment recommendations Connect with the Mayo Clinic’s School of Continuous Professional Development online at or on Twitter @MayoMedEd.

Lung Cancer Screening

Guest: Sebastian Fernandez-Bussy, M.D. Host: Darryl S. Chutka, M.D. (@ChutkaMD) Lung cancer is the second most common malignancy in both men and women.  Survival rates depend on how early the cancer is discovered, with a survival rate much higher in localized disease than for patients with distant metastases. Therefore, an early diagnosis becomes extremely important. One of the problems with early diagnosis is that until recently, we’ve not had an effective screening test for lung cancer. In this podcast, we’ll be speaking with Sebastian Fernandez-Bussy, M.D., an Interventional Pulmonologist from the Division of Pulmonary and Critical Care at the Mayo Clinic in Jacksonville, Florida, and we’ll discuss proven techniques for lung cancer screening. Specific topics: Benefits in survival in finding lung cancer at an early stage Candidates for screening patients at an increased risk for lung cancer Evidence showing the benefits of lung cancer screening Differences in radiation for chest CT scans used for screening vs. a typical diagnostic chest CT scan Frequency of indeterminate pulmonary nodules found on chest CT Insurance and Medicare coverage for lung cancer screening Connect with the Mayo Clinic’s School of Continuous Professional Development online at or on Twitter @MayoMedEd.
