MRI Can Monitor Transplanted Islets

...t proceeds over time. Monitoring islet survival by noninvasive imaging could give us the ability to detect and measure rates of islet loss under a variety of conditions, which could help develop procedures leading to better therapeutic outcomes." Pancreatic islet transplants are being investigated as a way to ...

Fight Back Against Inherited Sudden-Death Heart Condition

...ough history, physical examination and some simple noninvasive testing, doctors can tell someone with HCM how high their risk of sudden death is — around 1-in-100 each year for most HCM patients, but as high as 6-in-100 per year for others. That risk level will play a part in determining what treatments patients...

Patient’s Individual Cardiologist Best Judge For Deciding Appropriate Treatment In Chronic Coronary Artery Diseas

...one of the three potential treatments: medication, noninvasive angioplasty using balloons and/or stents to open clogged arteries, or coronary artery bypass graft (CABG) surgery to reroute blood through new vessels grafted into place. After the cardiologists made their recommendations, the patients were randoml...

Valve Disease Study Suggests New Public Health Concern

...Mayo Clinic cardiologist. An echocardiogram -- a noninvasive test that uses sound waves to create a moving picture of the heart -- is done to evaluate murmurs or causes of shortness of breath or chest pain or heart failure, and is ideal for detecting or confirming valve diseases, Dr. Nkomo says. Valve disea...

Emergency Heart Patients Do Better With Invasive Approach

Aggresive Therapy Needed for Cervical Spinal Cord Injuries

...tem to slow it down, says Dr. Gyanendra K. Sharma, noninvasive cardiologist and study co-author. With a cervical spinal cord injury, the influence of the sympathetic nervous system – called the fight or flight system because it responds to stress by enabling an increase in heart rate – can be injured or lost ...

Protein holds clue in the spread of bladder cancer

...uld be critical for the passage of a cancer from a noninvasive to an invasive phenotype," says Andrea Morrione, Ph.D., research assistant professor of urology at Jefferson Medical College of Thomas Jefferson University and Jefferson's Kimmel Cancer Center in Philadelphia. In some cases, he notes, proepithelin...

Efforts To Replace Reading Glasses Are In View

...how much or where to cut, he adds. ‘There are no noninvasive or minimally invasive procedures for presbyopia,’ said O'Donnell, 55, who explained that he started research on presbyopia when he began to notice his own near-sight failing. He held up his reading glasses: ‘I got sick of wearing these things.’ The...

Intractable Seizures Can Be Handled By A Three-Stage Brain Operation, Neurosurgeon

...possible to determine where they originated. Other noninvasive imaging techniques cannot accurately pinpoint where seizures begin. To overcome this problem, neurosurgeons place electrodes directly on the brain itself, which requires removing a portion of the bony cranium and cutting through the dura mater, the...

Terahertz Imaging Promises To Revolutionize Breast Cancer Treatments

...archers were able to distinguish both invasive and noninvasive breast carcinomas from healthy tissue. Twenty-two excised breast tissue samples were obtained from 22 women who underwent either wide local excision or mastectomy to remove breast cancer. All samples were first sliced and imaged with terahertz light...

PET Scans Help In Monitoring Progress of Lung Inflammation

...versity School of Medicine in St. Louis say that a noninvasive approach towards assessing lung inflammation could hasten the process of developing drugs for cystic fibrosis and pneumonia. // Positron emission tomography (PET) scans were used to monitor artificially induced inflammation in the lungs of healthy vo...

Positive Airway Pressure the Treatment for Sleep Apnea

..., said that CPAP is the most effective, relatively noninvasive and usually well-tolerated therapy. Epstein said that the treatment consists of a pressurized airflow through a mask that covers a patient's nose during sleep. This prevents pauses in breathing and restores oxygen levels. It also improves self-r...

'Inflatable-pants' heart failure therapy suffers due to lack of evidence.

...tion is called “External counterpulsation”(ECP), a noninvasive therapy to improve blood flow to the heart. This is most commonly used to relieve hard-to-treat chest pain for heart patients who are not candidates for surgery. The Centers for Medicare and Medicaid Services declined to expand its policy on exte...

New Test Identifies Candidates For Cardiac Defibrillator

... uncomfortable, unnecessary, and even dangerous. A noninvasive test has been developed recently to find out which of the patients are likely to benefit from the implantable cardiac defibrillator (ICD). The test was found to be accurate by a study which was sponsored by the NIH with the active participation of...

Measuring Urinary Protein Helps In Detecting Recurrent Bladder Cancer

...and poor sensitivity while interpreting results. A noninvasive urine test’s clinical utility was examined by the Anderson Cancer Center’s H. Barton Grossman. This is a test for the protein NMP22 which helps in detecting recurrent cancer. The study involved 668 patients who had a history of the ailment. The ur...
