Postpartum Stroke Study at Mayo Clinic

Posted on February 15th, 2013 by Gina Chiri-Osmond

“Postpartum stroke” is a stroke that occurs within six weeks of giving birth. Strokes are a focal brain problem causing loss of function, which occurs because of occlusion of the blood vessel causing lack of blood flow. As a consequence, that part of the brain stops functioning. This is a permanent problem that can cause disability. Although it is a rare condition, postpartum stroke has increased by as much as 80 percent over the last decade. We are conducting this study because there is a lot we do not understand about this condition, including specific causes of stroke, possible treatments or ways to prevent the stroke from occurring.

Mayo Clinic is conducting a study reviewing the medical notes and actual images of the brain and blood vessels of the brain that were obtained at the time when patients suffered from a postpartum stroke.

If you suffered a stroke within six weeks of delivery and are interested in participating in the study, please contact us at Please note that the comments section below is not the place to indicate your interest in the study. Please email us with your contact information including telephone number, email address, and mailing address, and we will contact you about participation in the study.

National Research Study on Lung Cancer Prevention

Posted on January 11th, 2013 by Gina Chiri-Osmond

Mayo Clinic in Rochester is a member of the Cancer Prevention Network (CPN) and is participating in a national research study on lung cancer prevention. You may be eligible to participate in this research study if you:

  • are age 45–79 .
  • are a current or former heavy smoker.
  • have never had cancer or have been cancer-free for at least 3 years.
  • are currently in good health.

What does this study involve?
This research study involves physical exams, ECGs, bronchoscopies, blood and urine tests, a chest CT scan, and taking the study medication Myo-Inositol (or placebo) twice a day for six months.

What is Myo-Inositol?
Myo-Inositol is a natural substance found in grains, seeds, and fruits.

Are there any risks involved?
If you choose to participate, you will be at risk for side effects from the medication and bronchoscopy procedure. Common side effects following bronchoscopy are coughing, sore throat, small streaks of blood in sputum, and mild elevation of temperature.

Will I get any benefit from being in the study?
If you agree to be in this study, there may or may not be any direct medical benefit to you. We hope what we learn from this study will benefit others at risk for lung cancer in the future.

Who can I contact for more information?
If you have questions, please call 507-538-1887.

This study is funded by the National Cancer Institute and conducted by the Cancer Prevention Network. CPN has more than 35 sites throughout the United States and Canada. Our goal is to learn how to prevent cancer before it starts.

There may be a CPN site close to you, so call now and become involved in a clinical research study today.

Arrival in Nepal: First blog post and photo from Mayo Everest team

Posted on April 19th, 2012 by Admin

From Mayo Everest team member Bryan Taylor, Ph.D.

Mayo team arrives safely in Kathmandu

Abu Dhabi international airport, 7am. Our team is huddled around a small table chugging coffee or alternative caffeinated beverage, eating a random assortment of pastries, and trying to get a WiFi connection to send messages to friends and family back home. Apparently standing waiving your tablet above your head doesn't help.

I didn't sleep too well last night. No one did. It may have had something to do with the long journey. Perhaps even the time change. The fact that Air Berlin had the audacity to land planes about 100 feet from our hotel bedroom window starting at 4:30am didn't help either. We have already played a little friendly game of poker. Those who have had the fortune to rather easily taking my money from me in the past will be surprised to know that I ended up with all the chips.

The airport is busy, bussling, vibrant. Outside, the cluster of dome shapped buildings set with the desert background makes the airport look not too dis-similar to Luke Skywalker's home planet of Tatooine in the Star Wars: A New Hope movie. Inside, above us the ceiling of the departure hall is a beautiful mosaic of oceanic blues and greens. Herds of people are lining up in front of their departure gates. I like to look at the destinations of the departing flights, playing that game of "I have been there!". Turns out I have seen very little of the Arabic nations. I smile at this notion as my mind wanders to potential future adventures.

We are tired but excited. Excited about the prospect of finally stepping foot in Nepal.It's three hours until we leave and I and have many questions about what awaits us on the other side of our short flight to Kathmandu. What will the city look like? Smell like? Sound like? Possiblly more importantly, will all of our reaserch gear be waiting for us unscathed and in tact when we land? Did it survive the journey? Will our North Face and Nat Geo colleagues be there? And what then? Then it's to work. Finally. It feels like the expedition has really started. It has all become rather real.

From Rochester to Abu Dhabi

Autographing the banner

Mayo Clinic On Everest- Plus 1 -   Mayo's Everest Expedition team left Minnesota yesterday with a warm sendoff from friends, family and media. Sporting new haircuts and Mayo baseball caps, they posed for cameras, did interviews and signed the expedition banner which they will take with them to Base Camp. We'll have more images over the next few days. Check out the feature on the youngest team member, Alex Kasak, by his hometown TV station in Austin, MN. The reporting has begun already, with Joel Streed sending back the first message via Twitter this morning:

Mayo Clinic Studies Climbers on Everest to Help Heart Patients at Home

Posted on March 21st, 2012 by Admin

It’s a natural laboratory for studying heart disease, lung problems, muscle loss, sleeping disorders and new medical technologies. It’s also the highest mountain in the world.

Mayo's Everest team: (l-r) Bryan Taylor, Ph.D.; Alex Kasak.; Amine Issa, Ph.D.; Andy Miller; Bruce Johnson, Ph.D.; Doug Summerfield, M.D.; and Joel Streed

Mount Everest’s extreme altitude puts climbers under the same conditions experienced by patients suffering from heart disease, obesity or advanced age. To take advantage of that, Mayo Clinic researchers are joining an expedition to Everest with National Geographic, The North Face and Montana State University. The expedition is funded by National Geographic and The North Face, with support from Montana State.  
The Mayo group will monitor up to nine climbers from base camp for the duration of the climb, which will run from mid-April to mid-May.

Mayo Clinic Heading to Mount Everest

Posted on March 17th, 2012 by Admin

Mayo Clinic will be sending five scientists to monitor a team of climbers attempting to scale Mount Everest this spring. The goal is to learn more about the physiology of humans at high altitude in order to help patients with heart conditions and other ailments. Mayo's team is headed by Bruce Johnson, Ph.D., a veteran researcher who has conducted similar studies at the South Pole and at Mt. Aconcaugua in South America (as covered by this blog and in Discovery's Edge). The climb is sponsored by The North Face, the outdoor equipment company, and National Geographic. Mayo Clinic and Montana State University are collaborating, MSU to study the geology of Everest and Mayo for medical research.

Advancing the Science will become Mayo's headquarters for all information and continuing coverage of the climb and the scientific studies being conducted. Mayo will also be sending its own correspondent, Joel Streed, of the Mayo Clinic News Network, to blog and send video reports from base camp. Several of Mayo's research team will also blog here on their impressions of Nepal and conditions on the mountain. In coming days you will see this site transform as we prepare to keep you informed. We'll be posting updates on the wide range of research projects planned and profiles of Mayo's scientific team. For an overview of the expedition, check out yesterday's NPR broadcast of Science Friday and hear host Ira Flatow interview expedition participants, including Mayo researcher Bryan Taylor, Ph.D.  You will also be able to follow exploits of the Mayo Everest team via Twitter at #MayoClinic #OnEverest.
