Scripps Green Hospital first to implant world's smallest implantable cardiac monitoring device

Scripps Green Hospital has become the first hospital in the United States to implant the world's smallest implantable cardiac monitoring device. Scripps Clinic cardiologist John Rogers, M.D., successfully completed the first implant of the Reveal LINQ- Insertable Cardiac Monitor (ICM) in 71-year-old San Diego resident Chuck Beal on Saturday.

Neurosurgeons use MRI-guided laser technology to treat deep brain tumor

Using a novel magnetic resonance imaging (MRI)-guided laser technology, neurosurgeons at UC San Diego Health System have successfully treated a malignant tumor deep inside a patient's brain. This is the first time that this FDA-approved laser-based treatment has been performed in California.

New research shows that saturated fat builds more fat, less muscle than polyunsaturated fat

New research from Uppsala University shows that saturated fat builds more fat and less muscle than polyunsaturated fat. This is the first study on humans to show that the fat composition of food not only influences cholesterol levels in the blood and the risk of cardiovascular disease but also determines where the fat will be stored in the body.

iASSIST device improves surgical precision, accuracy in total knee replacements

Each year, approximately 600,000 total knee replacement procedures are performed in the United States, a number that is expected to rise exponentially in the next decade as the population ages. Successful surgeries require precise alignment in the knee, a challenging task made even more daunting by the expected rise in procedures. To help meet this demand, UC San Diego Health System is the first in the nation to use iASSIST, a computer navigation system with Bluetooth-like technology that improves surgical precision and accuracy in total knee replacements, decreasing the need for revision surgery.

New radiation-free MRI test effectively diagnoses cancer in children

A new type of whole-body magnetic resonance imaging test could be an alternative to standard positron emission tomography/computed tomography imaging for assessing cancer in children and young adults, but without exposure to radiation that has been shown to increase the risk of secondary cancers in later life.

Head movement during fMRI may bias sampling toward subjects with lower cognitive ability

Kessler Foundation researchers have shown that discarding data from subjects with multiple sclerosis (MS) who exhibit head movement during functional magnetic resonance imaging (fMRI) may bias sampling away from subjects with lower cognitive ability.

iCAD total revenue for Q4 2013 increases 16.8% to $9.1 million

iCAD, Inc., an industry-leading provider of advanced image analysis, workflow solutions and radiation therapy for the early identification and treatment of cancer, today reported financial results for the three and twelve months ended December 31, 2013.

Researchers develop catheter-based device that provides 3-D imaging from inside heart, blood vessels

Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart, and potentially allow more of patients' clogged arteries to be cleared without major surgery.

Study examines brain activity of alcohol-dependent women

A new Indiana University study that examines the brain activity of alcohol-dependent women compared to women who were not addicted found stark and surprising differences, leading to intriguing questions about brain network functions of addicted women as they make risky decisions about when and what to drink.

Interhemispheric disconnectivity highlighted in bipolar disorder

Research shows that patients with bipolar I disorder have reduced white matter integrity, including in the corpus callosum, which connects the brain’s hemispheres.

Heritable bipolar phenotypes pinned down

A large study has pinpointed brain and behavioural traits that are genetically influenced and associated with bipolar I disorder.

Common mutations produce typical schizophrenia brain changes

Mutations in dopamine-related genes have a dose-response effect on prefrontal activation during emotional response inhibition in healthy adults, a study shows.

Being overweight may cause changes in brain that is crucial to appetite, emotions and memory

Being overweight appears related to reduced levels of a molecule that reflects brain cell health in the hippocampus, a part of the brain involved in memory, learning, and emotions, and likely also involved in appetite control, according to a study performed by researchers at SUNY Downstate Medical Center and other institutions.
