Heavy antibiotic use may raise colon cancer risk
Long-term, repeated antibiotic use might increase the risk for colon cancer, possibly by reducing overall bacterial diversity, researchers reported at the American Society of Clinical Oncology annual meeting. Patients who had taken penicillin were more likely to be diagnosed with CRC, and the risk increased as the number of exposures increased. The study backs other research demonstrating that microbiota have an effect on the development of gastrointestinal tract diseases, experts say. Gastroenterology & Endoscopy News (7/2014)

Exposure to microbial diversity tied to lower IBD risk
Researchers in Denmark found that people who were born after 1952 and lived on a livestock farm until age 5 were 50% less likely to develop inflammatory bowel diseases than the oldest people in the survey, likely due to differences in microbial diversity between urban and farm settings. The study supports the "hygiene hypothesis" that a lack of exposure to allergens, infectious pathogens and diverse bacteria suppresses immune system development, making people more susceptible to autoimmune and inflammatory diseases.

Experimental device detects gluten in food
A portable sensor that detects certain food proteins such as gluten is being developed by a California startup company. 6SensorLabs CEO Shireen Taleghani Yates, who has a gluten allergy, said she is trying to make the sensor sleek and convenient to use, and she intends to add capabilities for detecting other food allergens, such as nuts.

Study: Stress tied to fewer calories burned in women
Women who reported being stressed during the previous day burned fewer calories and had higher levels of insulin and lower rates of fat burn, according to a study in the journal Biological Psychiatry. Researchers said the findings may also be applicable to men but warrant further study. LiveScience.com (7/14)

Study: Fecal transplant safe in immunocompromised patients
Fecal transplantation is safe and effective for treating Clostridium difficile infections in immunocompromised patients, researchers report in The American Journal of Gastroenterology. A records review involving 75 adults and five children treated with fecal transplant for C. diff. infection showed an 89% cure rate and no incidents of infection related to fecal transplant, though some inflammatory bowel disease patients had disease flares following transplant.

Study links thiopurine therapy to elevated lymphoma risk
Patients with inflammatory bowel disease who are taking thiopurines have a higher incidence of lymphoma than the general population, but the elevated risk abates after thiopurine therapy is discontinued, a study found. The risk for men was higher than for women. The effect might be due to immunosuppression rather than DNA damage, the researchers wrote. Healio (free registration) (7/14)

Patient's Perspective
Making sacrifices for your health
"The last two summers have been the first years where having an ostomy did not make me angry. I went in the lake for the first time with my ostomy last summer (for a very short time) and saw that it was nice to take a dip but it wasn't worth the potential skin issues that came with laying there with a wet appliance on. But it was okay. My health was most important and if this was what I needed to deal with to be healthy, then it is worth that sacrifice." -- post from Marisa on the blog KeepingThingsInsideIsBadforMyHealth
