A study of 439 U.S. and Mexican-born Latinas seeking pregnancy and postpartum services at public health clinics in San Antonio uncovered elevated levels of depression among the more "Americanized" women, report researchers from The University of Texas School of Public Health and The University of Texas Health Science Center at San Antonio in the most recent online issue of the Maternal and Child Health Journal.

Researchers examine safety of Internet prescriber service providing erectile dysfunction medications
ROCHESTER, Minn. -- Online Internet shopping today offers many benefits. You can research a product in the privacy of your own home and purchase most anything by clicking a mouse. But should we be allowed to buy prescription drugs via the Internet, bypassing a traditional office visit or conversation with a physician?
CSIRO is investigating ways of controlling a devastating new wheat disease strain which could lead to a global wheat production and food supply crisis.
Cornell University in the United States, with funding from the Bill & Melinda Gates Foundation Global Development Program, has subcontracted CSIRO to undertake the research as part of the Durable Rust Resistance in Wheat project to tackle Ug99 – a strain of the fungus, wheat stem rust.
Breast cancer survivors continue to have a substantial risk of disease recurrence after five years of systemic therapy, according to a study published in the August 12 online issue of the Journal of the National Cancer Institute. Among breast cancer patients who were cancer-free five years after initiating systemic therapy, 89 percent remained recurrence-free at five years (approximately 10 years after a woman's initial diagnosis) and 80 percent remained recurrence free at 10 years (approximately 15 years after diagnosis).
Men with early prostate cancer who undergo radical prostatectomy have a lower rate of death due to prostate cancer than men who are followed without treatment, known as watchful waiting, according to a randomized controlled trial published in the August 12 online issue of the Journal of the National Cancer Institute. The benefit from the surgery, with respect to prostate cancer death rates, remained constant beyond 10 years, but the overall death rates in the two groups were not statistically different.
Hepatitis B Genotypes and Mutants May Influence Liver Cancer Risk
Infection with hepatitis B virus (HBV) causes liver cancer in some individuals, but not all strains of the virus are associated with the same degree of risk. If confirmed, the newly reported data could help target chemoprevention strategies in the future.
CHAMPAIGN – A new study of transfer RNA, a molecule that delivers amino acids to the protein-building machinery of the cell, challenges long-held ideas about the evolutionary history of protein synthesis.
In the study, researchers report that the dual functions of transfer RNA (reading the genetic blueprint for a protein, and adding a specific amino acid to the protein as it is formed) appear to have originated independently of one another. The new findings are detailed in the July 30 Public Library of Science (PLoS) ONE.
Adverse events from antibiotics cause an estimated 142,000 emergency department visits per year in the United States, according to a study published in the September 15, 2008 issue of Clinical Infectious Diseases.
"This number is an important reminder for physicians and patients that antibiotics can have serious side effects and should only be taken when necessary," said study author Daniel Budnitz, M.D., at the Centers for Disease Control and Prevention (CDC).
PROVIDENCE, R.I. [Brown University] — The apparent narrowing of the wage gap between working men and women in the last 30 years reflects changes in the type of women in the workforce, rather than in how much they're being paid, according to groundbreaking new research by Brown University economist Yona Rubinstein and Casey Mulligan of the University of Chicago. Rubinstein says the impression that the labor market treats women better today than three decades ago is a "statistical illusion." The findings are published in the August issue of The Quarterly Journal of Economics.
DALLAS – Aug. 12, 2008 – The development and repair of heart tissue and blood vessels is intimately tied to a tiny piece of ribonucleic acid (RNA) that is found nowhere else in the body, researchers at UT Southwestern Medical Center have found.
Because of its specificity to the cardiovascular system, this "microRNA" is an attractive potential target for therapeutic treatment, the researchers said.
Precisely targeted radiation therapy can eradicate all evidence of disease in selected patients with cancer that has spread to only a few sites, suggests the first published report from an ongoing clinical trial.
In the August 15, 2008, issue of Clinical Cancer Research, (published online August 12) researchers from the University of Chicago Medical Center report that targeted radiation therapy had completely controlled all signs of cancer in 21 percent of patients who had five or fewer sites of metastatic disease.
RIVERSIDE, Calif. – To make a discovery and get to name it is just about every scientist's dream. For one graduate student at UC Riverside that dream already has come true.
PHILADELPHIA – A combination of chemotherapy agents that have been tested in other tumor types appears to be a promising alternative to standard treatment for advanced non-small cell lung cancer, according to a report in the August 15 issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.
In a new study published today in PLoS Medicine, Eric Brunner from the Royal Free and University College London Medical School, London, and colleagues, examine the association between levels of C-reactive protein, a marker for inflammation in the blood, and the risk of type 2 diabetes. Previous research has suggested that raised levels of this marker are linked with an increased risk of diabetes but to date it has not been clear whether C-reactive protein actually causes the condition.
In a systematic review of antiepileptic drugs, Philippe Ryvlin (of the Hospices Civils de Lyon, France) and colleagues show that children with drug-resistant partial epilepsy enrolled in trials seem to have a greater response to placebo than adults enrolled in such trials. This finding is an important factor to consider when designing drug trials to be carried out in children with epilepsy.
