Coronary arterial calcium scans help detect overall death risk in the elderly

Measuring calcium deposits in the heart's arteries can help predict overall death risk in American adults, even when they are elderly, according to a new study published in the July issue of Journal of the American College of Cardiology.

Adult stem cells improve healing of broken bones

Adult stem cells improve healing of broken bones and could eventually serve as a new treatment for the 10 to 20 percent of fractures that fail to heal, according to a new study. The results were presented Monday, June 16, at The Endocrine Society's 90th Annual Meeting in San Francisco, by Froilan Granero-Molto, PhD, research associate of the University of North Carolina.

Combined PET and CT could be valuable noninvasive tool for determining stages of ovarian cancer

Combined positron emission tomography (PET) and computed tomography (CT) scanning of patients in the early stages of ovarian cancer can enable physicians to determine whether the cancer has spread to nearby lymph nodes without having to perform surgery, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

Study recommends development of standards for pediatric doses in nuclear medicine

Results of a recent survey of 13 pediatric hospitals in North America show a lack of universally applied standards for administering radiopharmaceutical doses to children undergoing nuclear medicine examinations, according to an article in the June issue of The Journal of Nuclear Medicine.

Computed tomography lung cancer screening no cure-all for smokers

Screening for lung cancer with computed tomography (CT) may help reduce lung cancer deaths in current and former smokers, but it won't protect them from other causes of death associated with smoking, according to a new study published in the July issue of the journal Radiology.

Physician Gainsharing programs reduce hospital spending

Giving physicians cash payments for reduced hospital spending can help control costs without sacrificing quality or access to care, researchers report in a study released today in the May/June 2008 issue of the journal Health Affairs. The issue is a thematic volume on health reform supported by a grant from the Robert Wood Johnson Foundation.

Researchers find link between altered dopamine activity and social anxiety disorder

Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction.

Effectiveness of decompression surgery in patients with cervical spinal cord injuries

Every year, nearly 12,000 individuals in the United States and Canada, mostly young adults, sustain a spinal cord injury (SCI). According to the Centers for Diseases Control and Prevention (CDC), SCI costs an estimated $9.7 billion each year in the United States alone.

Scans spot hidden tumors in Li-Fraumeni syndrome

Researchers at Dana-Farber Cancer Institute report that full-body PET/CT scanning detected unsuspected, treatable tumors in 3 of 15 patients with Li-Fraumeni syndrome (LFS), a rare genetic cancer syndrome for which no screening tests have been recommended.

New technique improves outcome for living donor liver transplants

The University of Alberta Hospital (UAH) is one of only a few centers in Canada that perform living donor liver transplantation, a surgical procedure developed in the late 1980s that expands the organ donor pool. About 80 liver transplants are done a year in Alberta, 10 of those being living-donor.

Long-term follow-up after percutaneous pulmonary radiofrequency ablation

Radiofrequency ablation (RFA) - an interventional treatment that "cooks" and kills lung cancer tumors with heat - greatly improves survival time from primary or metastatic inoperable lung tumors, according to a study released at the Society of Interventional Radiology's 33rd Annual Scientific Meeting.
