MITA Encourages CMS To Consider Diagnostic Endpoints In Coverage Decision For Beta Amyloid PET Imaging
Date: Feb-05-2013The Medical Imaging & Technology Alliance (MITA) have encouraged the Centers for Medicare & Medicaid Services (CMS) to consider diagnostic endpoints as the basis for its coverage of beta amyloid positron emission tomography (PET) imaging despite Medicare Evidence Development and Coverage Advisory Committee (MEDCAC)'s determination that there is not adequate evidence that the technology improves health outcomes...
Research Game Changer Proves That Breast Cancer Stem Cells Can Be Targeted To Stop The Disease From Returning And Spreading
Date: Feb-05-2013In a significant breakthrough, published last week, scientists prove for the first time that breast cancer stem cells, the driving force of a tumour, can be targeted in cells from patients; an approach that could increase the chances of survival for women with aggressive breast cancers...
Needless Abdominal CT Scans Can Be Avoided In Children, Study Says
Date: Feb-05-2013Researchers identify 7 factors to lessen radiation exposure in young, traumatic injury victims. A study of more than 12,000 children from emergency departments throughout the country in the Pediatric Emergency Care Applied Research Network (PECARN) has identified seven factors that can help physicians determine the need for a computed tomography (CT) scan following blunt trauma to the abdomen. Because CT scans pose radiation hazards for youngsters, the findings may enable doctors to determine which children do not need to be exposed to such tests after a traumatic injury...
Prostate Cancer Treatment Time Shortened By Novel Radiation Therapy Method
Date: Feb-05-2013According to a study in the Journal of the American College of Radiology, the use of volume-modulated arc therapy (VMAT) to deliver intensity-modulated radiation therapy (IMRT) to prostate cancer patients results in an overall reduction in treatment time of approximately 14 percent. The study was performed at Winship Cancer Institute of Emory University in Atlanta. Treatment with IMRT is increasingly standard for prostate cancer...
Measures Needed To Lessen The Adverse Mental Health Effects On Humanitarian Aid Workers In Uganda
Date: Feb-05-2013Latest research points to the high risk for mental health problems among staff working in humanitarian organizations in northern Uganda, due in large part to their work environment. A new study by researchers at Columbia's Mailman School of Public Health examined the mental health of 376 Ugandan workers at 21 humanitarian aid agencies and found that a significant number of the staff at these organizations experienced high levels of symptoms for depression (68%), anxiety disorders (53%), and posttraumatic stress disorder (PTSD) (26%), respectively...
Researchers Develop Automated Breast Density Test Linked To Cancer Risk
Date: Feb-05-2013Researchers at Moffitt Cancer Center and colleagues at the Mayo Clinic in Rochester, Minn., have developed a novel computer algorithm to easily quantify a major risk factor for breast cancer based on analysis of a screening mammogram. Increased levels of mammographic breast density have been shown in multiple studies to be correlated with elevated risk of breast cancer, but the approach to quantifying it has been limited to the laboratory setting where measurement requires highly skilled technicians...
Community Consultation Study Reveals Support For Research To Improve Care For Time-Sensitive Injuries, Exception From Informed Consent Research
Date: Feb-05-2013Traumatic injury - including car accidents, gunshot wounds, and stabbings - is the leading cause of death for people younger than 40 years old in the United States, but despite the toll of these injuries, few emergency medical interventions considered to be the standard of care for these injuries have been rigorously studied in clinical trials, because patients and their families are typically unable to consent to participate in research...
New Methods For Quantifying Antisense Drug Delivery To Target Cells And Tissues
Date: Feb-05-2013Powerful antisense drugs that target disease-associated genes to block their expression can be used to treat a broad range of diseases. Though antisense therapy has been proven effective, challenges remain in ensuring that the drugs reach their intended targets. Two new methods for detecting and measuring the levels of antisense drugs in cells that could accelerate the development of improved antisense drugs are described in an article in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc., publishers...
Wanting To Improve The World Starts With Teens Caring About Their Friends
Date: Feb-05-2013Craig Kielburger was only 12 years old when he travelled to India to see the plight of child laborers first hand. 14-year-old Malala Yousafzai took a stand against the Taliban with her campaign for women's education rights. Alongside these individuals, organizations like Teen Activist and Do Something rally teens to make a difference in their communities and beyond. Of course, it's not every teenager who will step forward and get involved. Under the right conditions, however, the desire to change the world can start early on in life...
Researchers Capture Key Moments In Cell Death
Date: Feb-05-2013Scientists at the Walter and Eliza Hall Institute have for the first time visualised the molecular changes in a critical cell death protein that force cells to die. The finding provides important insights into how cell death occurs, and could lead to new classes of medicines that control whether diseased cells live or die. Cell death, called apoptosis, is important for controlling the number of cells in the body. Defects in cell death have been linked to the development of diseases such as cancer and neurodegenerative conditions...
