From complex or serious conditions like cancer and heart disease to the latest news on research and wellness, host Dr. Halena Gazelka asks the questions and gets easy-to-understand answers from Mayo Clinic experts
Managing asthma in children
July 30, 2021
In childhood asthma, the lungs and airways become easily inflamed when exposed to certain triggers, such as inhaling pollen or catching a cold or other respiratory infection. Childhood asthma can cause bothersome daily symptoms that interfere with play, sports, school and sleep. In some children, unmanaged asthma can cause dangerous asthma attacks.
Childhood asthma isn't a different disease from asthma in adults, but children face unique challenges. The condition is a leading cause of emergency department visits, hospitalizations and missed school days.
The right treatment can keep symptoms under control and prevent damage to growing lungs.
On the Mayo Clinic Q&A podcast, Dr. Angela Mattke a Mayo Clinic pediatrician and host of "Ask the Mayo Mom" is joined by Dr. Manuel Arteta, a Mayo Clinic pediatric pulmonologist, to discuss managing asthma in children.
Stopping the spiral of the COVID-19 delta variant
July 28, 2021
Transmission of the COVID-19 delta variant is increasing.
“The delta variant is so highly contagious,” he says. “The number of delta viral particles in the upper respiratory system is reportedly 1,000 times higher than with the original COVID-19 virus. If we can't find ways to get people vaccinated, we are going to be in a world of hurt. And I don't say that to be alarmist. I say it to be a realist, based on what’s happening right in front of us.”
But Dr. Poland says the spiral can be stopped by getting higher rates of immunization.
"Getting a COVID-19 vaccine will prevent the development of worse and worse variants. It will prevent severe cases of hospitalization and death, even in the face of a variant,” he says. "The alternative is to lose another 600,000-plus Americans. Only this time it will, unfortunately, involve younger people."
Dr. Poland explains further, "Every time somebody gets infected with the delta variant, there's the opportunity for that virus to mutate and transmit to other people," says Dr. Poland. "This means that immunization rates to control herd immunity will probably have to be in the 85% to 95% range."
In this Mayo Clinic Q&A podcast, Dr. Poland continues to talk about the delta variant, breakthrough infections, booster shots and much more.
Making progress in treating glioblastoma
July 26, 2021
When it comes to malignant tumors in the brain and spinal cord, glioblastoma is the most common. Glioblastoma is an aggressive form of cancer that forms from cells called astrocytes in the brain or the spinal cord. Glioblastoma can occur at any age, but it's more common in older adults. It can cause worsening headaches, nausea, vomiting and seizures.
Glioblastoma can be difficult to treat. Current treatments include surgery, radiation and chemotherapy, but thanks to research and clinical trials, new therapies are being developed.
"We're coming together as a community to treat this," says Dr. Wendy Sherman, a Mayo Clinic neurologist. "We're getting more patients on trial and we're being smarter about our trials. It's an exciting time for our field, and I'm very hopeful that we're going to make progress on this."
A cure is often not possible, but disease management and treatment may slow progression of the cancer and decrease the side effects.
On the Mayo Clinic Q&A podcast, Dr. Sherman discusses glioblastoma diagnosis, treatment, and research.
Telemedicine before and after orthopedic surgery
July 23, 2021
In health care, one of the biggest changes during the COVID-19 pandemic was the expansion of telemedicine. Virtual visits have been used in many specialties, including orthopedics and orthopedic surgery. While the use telemedicine escalated out of necessity during the pandemic, Dr. Shawn O’Driscoll, a Mayo Clinic orthopedic surgeon, believes its use will continue to be used going forward.
"I think that the advantages to patients are really going to be the driving forces behind this," says Dr. O'Driscoll. "I think the key advantages are those that relate to access, convenience and cost."
While orthopedic surgery still requires in person appointments, telemedicine is beneficial for these patients before and after the operation.
"I've been very impressed with the ability to assess patients properly, even new patients, through telemedicine," says Dr. Joaquin Sanchez-Sotelo. a Mayo Clinic orthopedic surgeon. "When they come for surgery, they've already been evaluated, and there are no surprises. And after surgery, they can go home and follow-up care can be done virtually."
On the Mayo Clinic Q&A podcast, Drs. O'Driscoll and Sanchez-Sotelo discuss how telemedicine is helping orthopedics reach patients in new ways.
Tips to stay healthy while working from home
July 21, 2021
The COVID-19 pandemic has forced people to readjust in many ways, including some companies shifting to remote work. Working from a home office has its benefits, but it also comes with quite a few challenges. Virtual offices mean added screen time which can lead to eye strain, ear problems and too much time sitting in one place.
Living and working in the same space also can lead to challenges with setting boundaries and having an appropriate office space within the home.
"I think it's really important that if you are working from home, that you have office time and family time as separated as you can have," says Dr. Clayton Cowl, chair of the Division of Preventative, Occupational and Aerospace Medicine at Mayo Clinic. "And your home office needs to be a room — or at least a part of a room — where it's quiet, the light is appropriate, there's adequate ventilation, and it's set up ergonomically for you."
Occupational medicine is a specialty focused on helping workers stay at work and return to work.
On the Mayo Clinic Q&A podcast, Dr. Cowl, and Dr. Laura Breeher, a Mayo Clinic occupational medicine specialist, discuss tips and tricks for staying healthy while working from home.
Ventricular assist devices aid heart failure patients
July 19, 2021
A ventricular assist device, also known as a VAD, is an implantable mechanical pump that helps pump blood from the lower chambers of your heart, or ventricles, to the rest of your body. Although this device can be placed in the left, right or both ventricles of your heart, it is most frequently used in the left ventricle. When placed in the left ventricle it is called a left ventricular assist device, or LVAD.
A ventricular assist device is used in people who have weakened hearts or heart failure. A VAD may be implanted while the patient waits for a heart transplant or is working to get his or her heart strong enough to effectively pump blood on its own.
"Patients with end-stage heart failure may be out of breath brushing their teeth or sitting in the recliner watching TV," says Dr. John Stulak, a Mayo Clinic cardiovascular surgeon. "When a patient ends up having symptoms at rest, that's the telltale sign that this is end-stage heart failure. What the LVAD does is help the left side of the heart pump and decongest the heart and get all the blood moving forward again. The VAD helps patients get back to basically doing everything they want to do."
On the Mayo Clinic Q&A podcast, Dr. Stulak discusses technological advances in ventricular assist devices and how the therapy is underused.
On the verge of predicted COVID-19 surge with delta variant
July 15, 2021
The delta variant is being blamed for hot spots in the U.S. where cases of COVID-19 are on the rise. These hot spots account for most cases in the U.S. They are also the geographical areas that tend to have the lowest vaccination rates.
"This (delta variant) is the bad actor that we predicted it would be," adds Dr. Poland. "Our seven-day average is getting up to 19,000 cases a day in the U.S. We were down to 3,000. So we're starting to see, just as we predicted, a surge as people took masks off and as restrictions were lifted before we had achieved high rates of immunization."
In this Mayo Clinic Q&A podcast, Dr. Poland expands on how the highly transmissible delta variant continues to spread. He also talks about the possibility of COVID-19 vaccine boosters, explains how the Vaccine Adverse Event Reporting System works, and much more as he answers listener questions.
Be aware of the rare cancer called sarcoma
July 12, 2021
A sarcoma is a rare form of cancer that begins in the bones and in the softer connective tissues in the body. Sarcomas that begin in the bones are called "bone cancer," and sarcomas that forms in the tissues, including muscle, fat, blood vessels, nerves, tendons, and the lining of joints, are called "soft tissue sarcoma."
"These are rare cancers, and in adults, sarcomas comprise less than 1% of new cancers diagnosed every year," says Dr. Brittany Siontis, a Mayo Clinic medical oncologist. "So most people never hear about sarcoma. And that's why we're grateful to have Sarcoma Awareness Month, to try and bring more education to the population about this rare tumor."
Because this form of cancer is rare, it is important to seek care at a center that sees a high volume of sarcoma patients.
"When we're dealing with something that is so rare, it's really important to have a team of folks who are comfortable with these cancers, familiar with how these cancers behave, and know the data to help make the best treatment plan for each patient," says Dr. Siontis.
July is Sarcoma Awareness Month. On the Mayo Clinic Q&A podcast, Dr. Siontis discusses the various forms of sarcoma, treatment options, and research that's underway on new therapies and ways to treat sarcoma.
Working toward more diversity in orthopedic surgery
July 9, 2021
Of all the medical and surgical subspecialties, orthopedic surgery historically has had the lowest percentage of women and minorities. Mayo Clinic’s orthopedic surgery department is working to change that.
This summer, two female medical students are participating in an eight-week clinical and research internship in orthopedic surgery at Mayo Clinic in Rochester, Minnesota. The program was developed by Nth Dimensions, an organization that seeks to bring more women and minorities into the profession.
"I think it's important to have more women, more people of color, and diversity overall in orthopedic surgery for several reasons," says Dr. Kelechi Okoroha, a Mayo Clinic orthopedic surgeon and a graduate of Nth Dimensions. "Our population in America is very diverse. I think our patients deserve an equally diverse group of surgeons who are each equipped naturally with different cultural competencies to help treat them. Additionally, diversity in our surgeons will help decrease some of the inequalities you see in health care and treatment of patients today."
On the Mayo Clinic Q&A podcast, Dr. Okoroha, discusses his journey to becoming an orthopedic surgeon and his work as a mentor at Mayo Clinic.
The new work-life balancing act
July 7, 2021
The COVID-19 pandemic has altered the way people work. As vaccination rates increase, some people are returning to the office. But many companies have opted to keep their employees working from home permanently. This change has positive and negative side effects, including the mental health aspects of working from home.
"Any time there are changes, it can be challenging for people, particularly when you're not used to working from home," says Dr. Greg Couser, a Mayo Clinic psychiatrist and occupational medicine specialist. "I think there's a big issue for people of setting up good boundaries between work and home. So that's a big challenge."
Another challenge for many is missing the in-person contact with co-workers.
"We receive some of our identity from our work," says Dr. Couser. "And so, when we don't have that sort of daily contact with our colleagues, that shifts our identity just a little bit."
On the Mayo Clinic Q&A podcast, Dr. Couser discusses how to cope with the challenges of working from home.
