Vitamin Supplements Do Not Reduce Cancer Risk, More Evidence

US researchers studying the effect of beta carotene, vitamin C and vitamin E, either singly or in combination, on over 7,000 women found the supplements did not reduce their risk of getting cancer compared to women who did not take the supplements. However an expert who reviewed the study said that while the overall message was there was no link, it uncovered some interesting evidence that should not be overlooked.

EPA Makes Decision To Designate Areas Not Meeting Standards For Fine Particle Pollution, USA

EPA has notified 25 governors and 23 tribal leaders that certain areas in their states and tribal lands do not meet the agency's daily standards for fine particle pollution, also known as PM 2.5. "These designations are an important step in our steady march toward cleaner air," said EPA Administrator Stephen L. Johnson. "We will continue working with our state and tribal partners to meet these air quality standards.

In Lung Cancer, Silencing One Crucial Gene Disrupts Normal Functioning Of Genome

While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism. They say that "silencing" of a single gene in lung cancer led to a general impairment in genome-wide changes in cells, contributing to cancer development and progression. In the January 1, 2009, issue of

Vitamin D Deficiency Associated With Greater Rates Of Cesarean Sections

Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) found that pregnant women who are vitamin D deficient are also at an increased risk for delivering a baby by caesarean section as compared to pregnant women who are not vitamin D deficient. These findings currently appear on-line in the Journal of Clinical Endocrinology & Metabolism.

Cystic Fibrosis Patients’ Self-Assessment Of Health Can Predict Prognosis

Adult Cystic Fibrosis patients can provide important information that helps to predict their prognosis, according to research that asked 223 adult CF patients to assess their own health and well-being. "We wished to see whether patients themselves had clinically relevant insight to their disease, and we found that they did," said lead author of the study, Janice Abbott, Ph.D., of the University of Central Lancashire in England.

Activating The Lung’s Antioxidant Defense By Targeting Nrf2 Inhibits The Development Of Emphysema

Using a molecule similar to one found in an experimental cancer drug, researchers at the Johns Hopkins Bloomberg School of Public Health demonstrated that activation of a key component of the lung's antioxidant defense system, Nrf2, can prevent emphysema in mice. The researchers believe that activation of Nrf2 could be a novel target for therapies to prevent chronic obstructive pulmonary disease (COPD), which comprises emphysema and chronic bronchitis.

Common Food Additive Found To Increase Risk And Speed Spread Of Lung Cancer

New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease. The study also suggests that dietary regulation of inorganic phosphates may play an important role in lung cancer treatment.

Family Members Of Critically Ill Patients Want To Discuss Loved Ones’ Uncertain Prognoses

Critically ill patients frequently have uncertain prognoses, but their families overwhelmingly wish that physicians would address prognostic uncertainty candidly, according to a new study out of the University of San Francisco Medical Center. "Our interviews revealed that caregivers appear to believe that some uncertainty is unavoidable, and just the nature of life," said lead author Douglas White, M.D., M.A.S.

Anti-Fungal Drug Offers Great Benefits To Some With Severe Asthma

Some patients with severe asthma who also have allergic sensitivity to certain fungi enjoy great improvements in their quality of life and on other measures after taking an antifungal drug, according to new research from The University of Manchester in England. The findings were reported in the first issue for January of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
