Advanced CT scanners reduce patient radiation exposure, study finds

Posted: 21 Jun 2014 06:31 PM PDT

The use of advanced CT scanning equipment is helping to address the important concern of patient exposure to radiation. The study results provide information that will help in setting standards for radiation safety quality control in cardiovascular imaging.

Antidepressant use during pregnancy may lead to childhood obesity, diabetes

Posted: 21 Jun 2014 06:30 PM PDT

Maternal use of a class of antidepressants called selective serotonin reuptake inhibitors, or SSRIs, resulted in increased fat accumulation and inflammation in the liver of the adult offspring, researchers have demonstrated for the first time in an animal model. This raises new concerns about the long-term metabolic complications in children born to women who take SSRI antidepressants during pregnancy.

MA healthcare reform does not have early impact on disparities in cardiovascular care

Healthcare reform in Massachusetts has not yet impacted the likelihood of receiving coronary interventions by gender, race/ethnicity or socioeconomic status, a new research report concludes.

Telephone call is effective support when breast cancer treatment includes weight loss

Posted: 19 Jun 2014 06:59 AM PDT

A series of simple telephone calls can make a profound difference in helping women to meet their treatment goals for breast cancer, according to a randomized trial of women who are also obese. Women who received advice about weight loss from a trained lifestyle coach by telephone achieved weight loss that was still evident after two years, lowering their risk of breast cancer recurrence.

Possible new combination treatment for cancer

Posted: 19 Jun 2014 06:58 AM PDT

A new cancer treatment has been developed that has proved to be effective in mice. The treatment is based on newly discovered properties of the so-called BET bromodomain inhibitors. "The work is challenging, but we believe that the prospects for success with combination treatments are good," says the lead investigator.

Common genetic link in fatal autoimmune skin disease discovered

Posted: 19 Jun 2014 06:19 AM PDT

Autoimmune disease occurs when the body's own natural defense system rebels against itself. One example is pemphigus vulgaris (PV), a blistering skin disease in which autoantibodies attack desmoglein 3 (Dsg3), the protein that binds together skin cells. Researchers recently found a shared genetic link in the autoimmune response among PV patients that provides important new clues about how autoantibodies in PV originate.

Job loss linked with higher incidence of depression in Americans compared with Europeans

While job loss is associated with depressive symptoms in both the USA and Europe, the effects of job loss due to plant closure are much stronger in American workers as compared with European workers, a new study shows.

First Alabamian receives new retrievable, nonsurgical pacemaker

Posted: 18 Jun 2014 07:05 PM PDT

Developed for patients with bradycardia — a heart rate that is too slow — the Nanostim device is designed to be placed directly on the patient's heart without the visible lump, scar and insulated wires, or leads, required for conventional pacemakers.

Portable brain-mapping device allows researchers to 'see' where memory fails

Posted: 18 Jun 2014 03:46 PM PDT

The use of functional near infrared spectroscopy to map brain activity responses during cognitive activities allows researchers to "see" which brain region or regions fail to memorize or recall learned knowledge in student veterans with PTSD.

Primer for doctors' use of clinical genome, exome sequencing

Posted: 18 Jun 2014 03:46 PM PDT

Sooner than almost anyone expected, a new, genome-based technology for demystifying undiagnosed illnesses -- particularly rare childhood diseases -- is moving from research laboratories into general medical practice. Now, two leading scientists have sketched out what doctors need to know in order to use the new technology effectively.

Unintended danger from antidepressant warnings

Posted: 18 Jun 2014 03:46 PM PDT

Following 2003 FDA warnings about a potential danger to young people taking antidepressants, antidepressant use plummeted and attempted suicide by psychotropic drug poisoning increased proportionally by 22 percent. The FDA later revised the warning to recommend that physicians consider both the risk of prescribing the medication and the risk of not prescribing the medication, monitoring patients for thoughts of suicide and treating them as needed.
