High consumption of vitamin E either from diet or vitamin supplements may lower the risk of liver cancer, according to a study published July 17 in the Journal of the National Cancer Institute.

Treating chronic hepatitis C with milk thistle extract does not appear beneficial

CHICAGO – Use of the botanical product silymarin, an extract of milk thistle that is commonly used by some patients with chronic liver disease, did not provide greater benefit than placebo for patients with treatment-resistant chronic hepatitis C virus (HCV) infection, according to a study in the July 18 issue of JAMA.

Mammography screening shows limited effect on breast cancer mortality in Sweden

Breast cancer mortality statistics in Sweden are consistent with studies that have reported that screening has limited or no impact on breast cancer mortality among women aged 40-69, according to a study published July 17 in the Journal of The National Cancer Institute.

Since 1974, Swedish women aged 40-69 have increasingly been offered mammography screening, with nationwide coverage peaking in 1997. Researchers set out to determine if mortality trends would be reflected accordingly.

20-year quest ends as scientists pin down structure of elusive, heart-protective protein

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke. Importantly, the newly found channel strongly improves heart cell survival, demonstrating an essential life-saving role.

Milk thistle, taken by many people for liver disease, ineffective as treatment for hepatitis C

CHAPEL HILL, N.C. – Silymarin or "milk thistle," a popular herbal dietary supplement that many people take for liver ailments, works no better than placebo in patients with chronic hepatitis C infection.

That's the conclusion of a multicenter clinical trial published in the July 18, 2012 issue of the Journal of the American Medical Association.

"Patients ask me about milk thistle all the time," said Michael W. Fried, MD, lead author of the study, a professor in the University of North Carolina School of Medicine and director of the UNC Liver Center.

New roadmap suggests proven routes to ending health disparities

Major disparities exist along racial and ethnic lines in the United States for various medical conditions, but guidance is scarce about how to reduce these gaps. Now, a new "roadmap" has been unveiled to give organizations expert guidance on how to improve health equity in their own patient populations.

Researchers link Kawasaki Disease in childhood with increased risk of adult heart disease

Los Angeles – July 17, 2012 – Cedars-Sinai researchers have linked Kawasaki Disease, a serious childhood illness that causes inflammation of blood vessels throughout the body, with early-onset and accelerated atherosclerosis, a leading cause of heart disease in adults.

Study shows how aging impairs immune response

July17, 2012 — (Bronx, NY) — Researchers at Albert Einstein College of Medicine of Yeshiva University have uncovered one of the mechanisms by which aging may compromise the ability of the immune system to fight infections and respond to vaccines. The study, conducted in aging mice, shows that administering antioxidants may help reverse this loss of immune function. The findings were published online this month in the journal Cell Reports.

Report focuses on sustainability of infectious disease surveillance

ERIE, Pa. - Just as the globalization of trade and travel is rapidly evolving, so is the globalization of infectious diseases and the need for cooperative approaches to detect, prevent and control them, according to Dr. David Dausey, chair of the Mercyhurst University Public Health Department.

The outbreaks of Severe Acute Respiratory Syndrome (SARS) and avian influenza H5N1 in recent years showed how infectious diseases can significantly impact national economies and exposed the need for cooperation in detecting and controlling disease to protect populations and economies.

Study: Children abused by parents face increased cancer risk

WEST LAFAYETTE, Ind. - Frequent abuse by a parent can increase a child's cancer risk in adulthood, and the effects are especially significant when mothers abuse their daughters and fathers abuse their sons, according to new research from Purdue University.

Nanoscale scaffolds and stem cells show promise in cartilage repair

Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age. Reporting online June 4 in the Proceedings of the National Academy of Sciences, investigators produce an important component of cartilage in both laboratory and animal models.

Helping pigs to digest phosphorus

URBANA -- Phosphorus is a vital nutrient for pig growth, but pigs do not always digest it well. Research conducted at the University of Illinois has determined how adding various levels of the enzyme phytase to the diet improves how pigs digest the phosphorus in four different feed ingredients. Improving phosphorus digestibility has positive implications for producers' bottom lines as well as for the environment.

Physical health problems substantially increase use of mental health services, study shows

CORVALLIS, Ore. – People who experience a physical health problem, from diabetes and back pain to cancer or heart disease, are three times more likely to seek mental health care than patients who report having no physical ailment, according to a new study by Oregon State University researchers.

Penn expert addresses ethical implications of testing for Alzheimer's disease risk

VANCOUVER – Diagnostic tests are increasingly capable of identifying plaques and tangles present in Alzheimer's disease, yet the disease remains untreatable. Questions remain about how these tests can be used in research studies examining potential interventions to treat and prevent Alzheimer's disease.

Female money doesn't buy male happiness

Macho men whose partners earn more than they do have worse romantic relationships, in part because the difference in income is a strain for them, according to a new study by Patrick Coughlin and Jay Wade from Fordham University in the US. Conversely, men who are not so traditional in their masculinity do not place as much importance on the difference in income and, as a result, appear to have better quality relationships with their female partner. The work is published online in Springer's journal Sex Roles.
