Lifestyle choices may affect the long-term heart health of childhood cancer survivors

2014-07-28
(Press-News.org) A new study has found that following a healthy lifestyle may lower childhood cancer survivors' risk of developing the metabolic syndrome. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings indicate that children with cancer and adults who had cancer when they were children should receive information about how their lifestyle may influence their long-term health.

Adults who had cancer as children are known to be at increased risk for the metabolic syndrome, a group of risk factors that increases the likelihood of developing heart disease and other health problems such as diabetes and stroke. People with the metabolic syndrome have some combination of factors including high blood pressure, abnormal cholesterol and glucose levels, and increased body fat.

Kirsten Ness, PT, PhD, of St. Jude Children's Research Hospital in Memphis, and her colleagues looked to see if lifestyle habits might affect cancer survivors' risk of developing the metabolic syndrome. The team studied 1598 childhood cancer survivors who were cancer-free for at least 10 years. Questionnaires and tests helped the researchers assess whether the participants followed healthy lifestyle recommendations issued by the World Cancer Research Fund and American Institute for Cancer Research. Those who met at least four of seven recommendations were classified as following the guidelines. "This study is unique because of the large, well characterized population of survivors of various diagnoses that we studied, many years from their original cancer diagnosis," said Dr. Ness.

The metabolic syndrome was present in 31.8 percent of the participants, and 27.0 percent of participants followed the healthy lifestyle guidelines. Females who did not follow the guidelines were 2.4 and males were 2.2 times more likely to have the metabolic syndrome than those who followed the guidelines.

"These findings are important because they indicate that adults who were treated for cancer as children have the opportunity to influence their own health outcomes," said Dr. Ness. "Cancer survivors should not smoke. In addition, adopting a lifestyle that includes maintaining a healthy body weight, regular physical activity, and a diet that includes fruits and vegetables and that limits refined sugars, excessive alcohol, red meat, and salt has potential to prevent development of the metabolic syndrome."

Nicotine found to inhibit DNA-strand break caused by a certain carcinogen in smoke

2014-07-28
A new in vitro study has revealed that nicotine and cotinine, a metabolite of nicotine, can potentially inhibit DNA damage caused by a certain carcinogen in smoke. The carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone or NNK is produced during the curing of tobacco leaves and ultimately ends up in the tobacco smoke. Once inhaled, it is metabolised in the lung and liver, where it is activated by a variety of enzymes called Cytochrome P450 (CYP). Previous research in mice has revealed that nicotine can partially interfere with the activation of NNK, and this has ...

Dinosaurs fell victim to perfect storm of events, study shows

2014-07-28
Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago. They found that in the few million years before a 10km-wide asteroid struck what is now Mexico, Earth was experiencing environmental upheaval. This included extensive volcanic activity, changing sea levels and varying temperatures. ...

Hepatitis C virus genotype 1 is most prevalent worldwide

Hepatitis C virus genotype 1 is most prevalent worldwide
2014-07-28
In one of the largest prevalence studies to date, researchers from the U.K. provide national, regional, and global genotype prevalence estimates for the hepatitis C virus (HCV). Findings published in Hepatology, a journal of the American Association for the Study of Liver Diseases, indicate that genotype 1 is the most prevalent worldwide, with over 83 million patients infected of which one-third reside in East Asia. Genotype 3, at just over 54 million cases, is the next most prevalent, followed by genotypes 2, 4, 6, and 5. Despite efforts to control HCV, it remains one ...

New species of mayfly discovered in India

New species of mayfly discovered in India
2014-07-28
Scientists have discovered a new species of mayfly in the southern Western Ghats, a mountain range along the west coast of India. In fact, this is the first time that any mayfly belonging to the genus Labiobaetis has been collected in peninsular India. The new species, called Labiobaetis soldani, "is named in honor of Dr. T. Soldan for his substantial contribution to the understanding of the Ephemeroptera of Palaearctic and Oriental realms," according to the authors of a study that describes the new mayfly in the Journal of Insect Science. The larvae have light-brown ...

Scientists discover new, noncommittal mechanism of drug resistance

Scientists discover new, noncommittal mechanism of drug resistance
2014-07-27
DURHAM, N.C. -- Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. These permanent mutations were once thought to be the only way for drug-resistant strains to evolve. Now a new study has shown that microorganisms can use a temporary silencing of drug targets -- known as epimutations -- to gain the benefits of drug resistance without the commitment. Though the new mechanism was discovered in a fungus called Mucor circinelloides, it is likely to be employed by other fungi as well as ...

Study: Climate change and air pollution will combine to curb food supplies

2014-07-27
Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution — specifically ozone pollution, which is known to damage crops. A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security. The study looked in detail at global production of four leading food crops — rice, wheat, corn, ...

Drugs used to treat lung disease work with the body clock

2014-07-27
Scientists from The University of Manchester have discovered why medication to treat asthma and pneumonia can become ineffective. The findings, published in Nature Medicine, show that drugs widely used to treat lung diseases work with the body clock. In the UK pneumonia, which is caused by an infection, affects around 1 in 1000 adults each year and is more serious for babies, young children, the elderly, smokers and those with an underlying health condition. More than 5 million people in the UK are affected by asthma and the NHS spends around £1 billion a year ...

New drug target can break down cancer's barrier against treatment

2014-07-27
CANCER RESEARCH UK scientists at Barts Cancer Institute have found that targeting a molecule in blood vessels can make cancer therapy significantly more effective, according to research published in Nature today (Sunday). The team at Barts Cancer Institute, part of Queen Mary University of London, have found that a molecule, called focal adhesion kinase (FAK), signals the body to repair itself after chemotherapy or radiotherapy, which kill cancer cells by damaging DNA. When the researchers removed FAK from blood vessels that grew in melanoma or lung cancer models, both ...

Engineers across the globe have been racing to design smaller, cheaper and more efficient rechargeable batteries to meet the power storage needs of everything from handheld gadgets to electric cars. In a paper published today in the journal Nature Nanotechnology, researchers at Stanford University report that they have taken a big step toward accomplishing what battery designers have been trying to do for decades – design a pure lithium anode. All batteries have three basic components: an electrolyte to provide electrons, an anode to discharge those electrons, and ...

New tools help neuroscientists analyze 'big data'

2014-07-27
In an age of "big data," a single computer cannot always find the solution a user wants. Computational tasks must instead be distributed across a cluster of computers that analyze a massive data set together. It's how Facebook and Google mine your web history to present you with targeted ads, and how Amazon and Netflix recommend your next favorite book or movie. But big data is about more than just marketing. New technologies for monitoring brain activity are generating unprecedented quantities of information. That data may hold new insights into how the brain works ...
