Electronic cigarettes: many questions, limited research

August 5, 2014 – Electronic cigarettes (ECIGs) are booming in popularity—but there's still only limited evidence on their potential health risks, or their advertised benefits in helping people to quit smoking, according to a research review in the July/August Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine.

Genetic testing of tumor is recommended for colorectal cancer patients

Bethesda, MD (Aug. 5, 2014) — Of the 143,000 patients diagnosed with colorectal cancer annually in the U.S., up to 25 percent have a familial risk of colorectal cancer. A new guideline from the U.S. Multi-Society Task Force on Colorectal Cancer recommends genetic testing of tumors for all newly diagnosed colorectal cancer patients.

Eating more dietary pulses can increase fullness, may help manage weight

TORONTO, Aug. 5, 2014 – Eating about one serving a day of beans, peas, chickpeas or lentils can increase fullness, which may lead to better weight management and weight loss, a new study has found.

A systematic review and meta-analysis of all available clinical trials found that people felt 31 per cent fuller after eating on average 160 grams of dietary pulses compared with a control diet, according to senior author Dr. John Sievenpiper of St. Michael's Hospital's Clinical Nutrition and Risk Factor Modification Centre.

Social networking is key to helping bugs spread, study shows

Fresh discoveries about how bacteria co-operate with each other when causing infection could help scientists identify animal diseases that might transmit to people.

Bugs that can co-operate best with each other are most likely to be able to jump to new species, including humans, a new study shows.

Bacteria interact by releasing molecules to help them adapt to their environment – for example, when killing competing infections in their victim. They co-ordinate these actions by releasing tiny amounts of chemicals as signals.

Smart bacteria help each other survive

The body's assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the person's health.

The bacteria Haemophilus influenzae is a type of bacteria in the respiratory tract that can cause ear infections and worsen the prognosis for COPD patients. In rare cases, it can also lead to meningitis and septicaemia.

Rituals can help older people remember to take their asthma meds

Storing it in the bathroom and making it part of a daily routine may be helpful advice that doctors can give their older asthmatic patients who struggle to remember to take their daily prescribed medication. This advice comes from Alex Federman, Associate Professor of Medicine at the Icahn School of Medicine in New York City, senior author of a study which discusses how elderly asthmatics cope with taking their inhaled corticosteroid medication as prescribed. The findings appear in the Journal of General Internal Medicine, published by Springer.

Clues to the ageing of tendons unlocked for the first time

University of Liverpool scientists have examined the mechanisms that cause ageing in the tendons of horses, opening up the possibility of better treatment for humans.

It has been understood for many years that tendons are highly prone to injury and that this likelihood increases as they age. Why this happens, is currently poorly understood

Surprise discovery could see graphene used to improve health

A chance discovery about the 'wonder material' graphene – already exciting scientists because of its potential uses in electronics, energy storage and energy generation – takes it a step closer to being used in medicine and human health.

Researchers from Monash University have discovered that graphene oxide sheets can change structure to become liquid crystal droplets spontaneously and without any specialist equipment.

With graphene droplets now easy to produce, researchers say this opens up possibilities for its use in drug delivery and disease detection.

Scientists call for increased conservation efforts to save black bears

COLUMBIA, Mo. – Between 1880 and 1920, the Central Interior Highlands (CIH), consisting of Missouri, Oklahoma and Arkansas, saw the height of deforestation that also decreased the habitat for black bears and other forest species. To combat the decline of black bears and repopulate the mountainous region, more than 250 bears from Minnesota and Manitoba were relocated to Arkansas in the 1950s and 1960s.

Researchers determine why tendons break down with age

Scientists at Queen Mary University of London (QMUL) have identified differences in the proteins present in young and old tendons, in new research that could guide the development of treatments to stop tissue breakdown from occurring.

Tendon structure in horses is similar to humans, and both face common injuries. The researchers used a horse model to undertake a thorough analysis of all the proteins and protein fragments present in healthy and injured tendons.

Mammography benefits women over 75

OAK BROOK, Ill. – Mammography-detected breast cancer is associated with a shift to earlier stage diagnosis in older women, subsequently reducing the rate of more advanced, difficult-to-treat cases, according to a new study published online in the journal Radiology. Researchers said the findings lend support to regular mammography screening in women ages 75 and older.

Boost for cancer prevention research

Queen's University scientists are helping to spearhead a new £6 million initiative to find better ways to prevent cancer.The new initiative, led by Cancer Research UK with matching investment from the BUPA Foundation, aims to support cutting-edge research to find better ways to prevent cancer.It is estimated that more than four in ten cancer cases could be prevented by lifestyle changes, such as not smoking, keeping a healthy body weight, cutting back on alcohol, eating a healthy diet, keeping active and staying safe in the sun.Professor Frank Kee, who directs the UKCRC Centre of Excellence

Research explores why interval walking training is better than continuous walking training

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) suggests that training with alternating levels of walking intensity (interval training) could be better than walking at a constant speed to help manage blood sugar in people with type 2 diabetes. The research is by Dr Thomas Solomon, University of Copenhagen, Denmark, and colleagues.

Study predicts hepatitis C will become a rare disease in 22 years

Effective new drugs and screening would make hepatitis C a rare disease by 2036, according to a computer simulation conducted by The University of Texas MD Anderson Cancer Center and the University of Pittsburgh Graduate School of Public Health. The results of the simulation are reported in the August 5 edition of the journal Annals of Internal Medicine.

Scientists uncover combustion mechanism to better predict warming by wildfires

Scientists have uncovered key attributes of so-called "brown carbon" from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material's warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the University of Montana in the journal Nature Geosciences this week.
