The study included 24,111 participants and showed that blood transfusion was associated with nearly four times increased risk for 30-day death.
Running and jumping exercises are most effective for strengthening bones in children, as they stimulate new bone growth where it is needed. Unlike swimming or biking, these activities do not affect longitudinal growth, making them a recommended choice.
Researchers examined the effect of treatment delay on patients treated with external-beam radiation for prostate cancer. The study found that a delay within certain limits does not alter ultimate clinical outcome, but using hormone therapy during this time should be avoided in men with favorable risk factors.
A recent VA study found that rural veterans have lower physical and mental health scores compared to urban veterans. The disparity persists even after adjusting for socioeconomic factors, suggesting access to care may be a key factor. The study's findings support the need for expanded healthcare delivery systems in rural areas.
Researchers analyzed claims for over 1.2 million North Carolina Medicaid enrollees between 1998 and 2000, finding a 22.8% annual rise in prescription drug costs due to increased prescribing of six new medications. The study suggests improving cost-effective prescribing practices to control rising expenditures.
The new center will provide tools for SNP selection, discovery, and analysis, enabling researchers to identify genetic markers associated with diseases. The center aims to make this capability accessible to many biomedical researchers, leading to a better understanding of human genetic variation and its association with disease.
The CHICA system combines patient-relevant pediatrics guidelines with family information to enable tailored care. Pediatricians receive customized clinical reminders, improving health outcomes for 55,000 patients in its first year.
Researchers developed a new technique to predict which proteins are prone to misfold and at what point the folding process breaks down. This could help identify causes of amyloid-related diseases and provide insights into more prevalent conditions like cancer and heart disease.
International society agrees on fat stem cell clinical applications for repairing bone defects, promoting blood vessel growth in tissues and treating cardiac diseases. The best use of this technology is expected to be developing therapies using patients' own cells.

By administering precise doses of radiation at the tumor site, IMRT can spare patients from skin irritation, breakdown, and scarring of the lungs.
A case-control study of 300 bladder cancer patients and 300 control subjects found higher levels of arylamine-hemoglobin adducts in cancer patients than in control subjects. The findings suggest exposure to arylamines is a causal factor for most cases of bladder cancer in humans, with potential non-smoking-related sources identified.
