Gene variant boosts risk of fatty liver disease

Researchers at UT Southwestern Medical Center have found that individuals who carry a specific form of the gene PNPLA3 have more fat in their livers and a greater risk of developing liver inflammation.

New tool for early diagnosis of breast cancer

Scientists from Finland, Germany and the ESRF have developed a new X-ray technique for the early detection of breast cancer. This allows a 3D visualization of the breast with a high spatial resolution and is extremely sensitive to alterations in the tissue, such as those generated by cancer. This technique could be used in the next years in hospitals. It may help doctors to detect tumours with greater precision than is possible using current X-ray mammography.

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.
