Using a pacifier for too long may be detrimental to your child's speech. Research published in the open access journal BMC Pediatrics suggests that the use of bottles, pacifiers and other sucking behaviors apart from breast-feeding may increase the risk of subsequent speech disorders in young children.

The proportion of in vitro fertilization (IVF) multiple births was lower in the eight states that provide insurance coverage for couples seeking IVF treatment, primarily due to fewer embryos transferred per cycle, Yale School of Medicine researchers report in an abstract presented at the American Society for Reproductive Medicine meeting in Atlanta, Georgia, October 17-21.

DURHAM, N.C. -- Young men who voted for Republican John McCain or Libertarian candidate Robert Barr in the 2008 presidential election suffered an immediate drop in testosterone when the election results were announced, according to a study by researchers at Duke University and the University of Michigan.

In contrast, men who voted for the winner, Democrat Barack Obama, had stable testosterone levels immediately after the outcome.

Female study participants showed no significant change in their testosterone levels before and after the returns came in.

Molecules that may hold the key to new ways to fight cancer and other diseases have been found to play an important role in regulating circadian rhythm, says Liheng Shi, a researcher in Texas A&M's Department of Veterinary Integrative Biosciences.

Circadian rhythm is the roughly 24-hour cycle of physiological activities of humans, animals and even bacteria, Shi explains.

Twenty years of screening for breast and prostate cancer – the most diagnosed cancer for women and men – have not brought the anticipated decline in deaths from these diseases, argue experts from the University of California, San Francisco and the University of Texas Health Science Center at San Antonio in an opinion piece published in the "Journal of the American Medical Association."

GAINESVILLE, Fla. — You might not know what it's called, but if you've had general anesthesia before surgery, especially after an accident, it is likely you have received Sellick's maneuver. That's when fingers are pressed against a patient's throat to prevent regurgitation and spilling of stomach contents into the airway and lungs while anesthesia is being administered.

Such regurgitation could result in serious lung damage and even death.

Contrary to the findings of some studies, new research indicates that augmenting antidepressant therapy with an omega-3 fatty acid supplement does not result in improvement in levels of depression in patients with coronary heart disease, according to a study in the October 21 issue of JAMA.

Less than one-third of patients hospitalized for heart failure and participating in a quality improvement registry received a guideline-recommended treatment of heart failure, aldosterone antagonist therapy, according to a study in the October 21 issue of JAMA.

A study that includes twins finds that the risk of hip fracture was significantly increased following a diagnosis of cardiovascular disease (CVD), with analysis also suggesting a genetic predisposition to the development of CVD and fractures, according to a study in the October 21 issue of JAMA.

A relative utility curve is a simple method to evaluate risk prediction in a medical decision-making framework, according to a commentary published online October 20 in the Journal of the National Cancer Institute.

Risk prediction models that are based on medical history or the results of tests are becoming common in the cancer literature and are used to provide additional information to those who are involved in making treatment decisions on the basis of estimated risk.

Upton, NY -- An international team of researchers from the United States, Korea, and France has sequenced and analyzed the genomes of two important laboratory strains of E. coli bacteria, one used to study evolution and the other to produce proteins for basic research or practical applications. The findings will help guide future research and will also open a window to a deeper understanding of classical research that is the foundation of our understanding of basic molecular biology and genetics.

Patients with chronic hepatitis C and advanced liver disease who drink three or more cups of coffee per day have a 53% lower risk of liver disease progression than non-coffee drinkers according to a new study led by Neal Freedman, Ph.D., MPH, from the National Cancer Institute (NCI). The study found that patients with hepatitis C-related bridging fibrosis or cirrhosis who did not respond to standard disease treatment benefited from increased coffee intake. An effect on liver disease was not observed in patients who drank black or green tea.

Hepatocellular carcinoma (HCC) or primary liver cancer forms in the epithelial tissue of the liver and is most commonly caused by the hepatitis B virus (HBV) or hepatitis C virus (HCV). In the U.S., the National Cancer Institute (NCI) estimates that 15,000 men and 6,000 women are diagnosed with HCC each year. Worldwide, HCC accounts for 632,000 cases with the highest regions being Western Pacific and Africa according to a 2004 World Health Organization (WHO) report.

A happy youth can influence where a fruit fly chooses to live as an adult, according to new research in the American Naturalist. The study, led by Judy Stamps from the University of California at Davis, provides new insight into how animals choose places to live and raise their young.

A targeted chemotherapy for the treatment of skin cancer is one step closer, after a team of University of Alberta researchers successfully synthesized a natural substance that shows exceptional potential to specifically treat this often fatal disease.

U of A chemistry professor Dennis Hall said after three years of work, his research team has successfully produced the substance called Palmerolide A.
