Chemical messenger controls bone growth in embryos, study finds

Researchers have discovered a chemical messenger called fibroblast growth factor 18 (FGF 18) that regulates bone development in growing embryos. FGF 18 appears to coordinate both the lengthening and hardening of bones, which may lead to new understanding of diseases such as achondroplasia and osteoporosis.

High Hep C levels found among young low-income women

A UCSF study found high levels of HCV infection among young low-income women in San Francisco, with injection drug use and HSV-2 co-infection contributing to transmission. The study also highlights the need for public health efforts beyond needle exchange programs to address non-needle drug use and sexually transmitted diseases.

U-M scientists find new genetic marker for prostate cancer

Researchers at the University of Michigan have identified a gene, AMACR, which triggers production of a specific enzyme involved in fat metabolism. The protein is detected in over 95% of localized prostate cancer cells and shows high sensitivity and selectivity ratings for diagnostic purposes.

Cellular link between sleep apnea and atherosclerosis found

A study led by Dr. Lena Lavie found that sleep apnea patients have increased adhesion molecules and free radicals on their white blood cells, which contribute to the development of atherosclerosis. Effective treatment with CPAP may not reverse this process, highlighting the need for further research.

Genetic variants put some patients at risk for particular drug reactions

A study by Dr. David Veenstra at the University of Washington identified two genetic variants associated with an increased risk of severe bleeding incidents in patients taking warfarin. Patients with these variants required longer time to achieve stable dosing, suggesting potential for dose adjustment and closer monitoring.

Low socioeconomic status may influence quality of breast cancer treatment

A recent study found that women with lower incomes and those insured by Medicaid had worse breast cancer treatment outcomes, including later-stage diagnoses, reduced radiation therapy, and higher mortality rates. Socioeconomic factors accounted for most of the disparities in these outcomes.

Hormone replacement therapy may be associated with increased ovarian cancer risk

A new study found that hormone replacement therapy, particularly estrogen alone, may increase the risk of epithelial ovarian cancer in postmenopausal women with an intact uterus. Women who used sequential progestins with estrogens had a higher risk of developing ovarian cancer compared to those who never used HRT.

Primate bushmeat : Populations exposed to simian immunodeficiency viruses

A study found that nearly 800 monkeys in Cameroon were infected with simian immunodeficiency viruses, highlighting the risk of human exposure through hunting and handling primates. The diversity among the viruses suggests a high degree of human exposure to SIVs.

Study links gene to success of a treatment for high blood pressure

A genetic variant in the adducin gene has been found to be associated with a significant reduction in heart attack and stroke risk when patients take low-dose diuretics. The study found that individuals with this variant were twice as likely to avoid cardiovascular events when treated with diuretics.
