Mayo Clinic Researchers Seek Solutions for Treatment Resistant Depression

Editor’s note: The following post is by Susannah Tye, Ph.D., researcher in Mayo’s Department of Psychiatry and Psychology. She and her team will be presenting at the Society for Neuroscience meeting in Washington, D.C. next week.

Susannah Tye, Ph.D.

An important issue in the treatment of depression is development of new and effective treatments for those patients that do not respond effectively to available antidepressant therapies. Such individuals are diagnosed with treatment resistant depression. Without effective treatment, these individuals can suffer for months or years limited or no relief from their symptoms. Researchers within the Mayo Clinic Depression Center are investigating the reasons why some patients do [...]

Photon counting CT Scanner makes research debut

image

Dr. Cynthia McCollough of Mayo Clinic and Dr. Thomas Flohr of Siemens.

The arrival of a new CT scanner at Mayo Clinic is not usually worthy of a ribbon cutting ceremony, but this isn't your ordinary scanner. Destined solely for research, the first photon-counting-detector-based spectral CT  to be put into service anywhere was recently delivered to Mayo's Radiology Research Division. Obtained through a grant from the National Institutes of Health, the machine provides spatial resolution and material discrimination sensitivity at much lower radiation doses than conventional scanners. Reducing radiation exposure wherever possible has been a major objective for Cynthia McCollough, Ph.D. (sharing the scissors duty here). While the photo counting scanner will [...]

Kidney cancer survivor joins Mayo experts to share the changing treatment of kidney cancer


Cynthia Chauhan joins Winston Tan, M.D., and Al Copland, Ph.D., both from the Mayo Clinic in Florida, for our second blog post in a lengthy series about kidney cancer. Cynthia is a Mayo Clinic patient who is a kidney and breast cancer survivor, leader of a kidney cancer survivor group, and patient advocate. Cynthia would like to share her thoughts on clear cell renal cell carcinoma (ccRCC), the most common form of kidney cancer and the diagnosis that she received over 16 years ago.

Chauhan: ccRCC is an aggressive cancer which, with the exception of high dose IL2, a difficult treatment with efficacy in only seven percent of ccRCC patients, is only treatable not curable when it metastasizes. When kidney cancer kills, [...]

New Sickle Cell Disease Guidelines from the National Heart, Lung and Blood Institute

A team of international experts including M. Hassan Murad, M.D., Mayo Clinic Preventive Medicine and Mayo Clinic Kern Center for the Science of Health Care Delivery, has published new clinical guidelines for treatment of sickle cell disease (SCD) in this week’s Journal of the American Medical Association. Sickle cell disease is an inherited blood disorder — a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout the body, resulting in anemia, infections and pain.

SCD affects nearly 100,000 people in the United States and is associated with many acute and chronic complications requiring immediate medical attention. While two strongly-recommended, effective therapies -- hydroxyurea and long-term blood transfusions -- have been available, they are underused.

Mayo Clinic and Karolinska Institutet Celebrate 20 years

Karolinska

It's been two decades since researchers from Mayo began annual scientific meetings with their counterparts at Karolinska, which is one of the top medical universities in Europe and the world. Beginning with investigators studying  metabolism issues, the relationship grew to include educational exchanges, many other medical disciplines and even organizational and planning sessions. Upwards of 80 delegates are arriving from Stockholm for two days of seminars, presentations and group meetings this week in Rochester. Heading the delegation will be Karolinska's president and vice chancellor, Dr. Anders Hemsten.

Mayo and Karolinska find that they speak the same language - and I don't mean English. It's the ultimate interest in finding answers for [...]
