Study finds more accurate method to diagnose pancreatic cancer Posted: 06 Nov 2013 05:24 PM PST Researchers have found a more accurate laboratory method of diagnosing pancreatic cancer, the fourth leading cause of cancer death in the United States. The method uses identification of four traits found in microscopic biopsies of pancreatic tissue.

Buffet dish sequences may prompt healthier choices Posted: 06 Nov 2013 05:24 PM PST Most people are unaware that food order biases what ends up on their plates: the first food in line is taken the most and biases what else is taken. This influence is so strong that in one study researchers found that two-thirds of an individual's plate is filled with the first three items they encounter, thus food order can be leveraged to encourage selection and intake of healthier foods.

Breastfeeding possible deterrent to autism Posted: 06 Nov 2013 05:24 PM PST The emergence of autism in young children appears to result from dysmyelination of brain neurons, related to inadequate supply of insulin-like growth factor (IGF) in the newborn. The deficiency of IGF in affected infants may be due to a combination of genetic and environmental factors yet to be determined. If this hypothesis is correct, breastfeeding in particular could increase IGF levels, thereby compensating for an inborn deficiency of the growth factor.

Lower education levels linked to unhealthy diets Posted: 06 Nov 2013 05:22 PM PST People with lower levels of education may eat larger amounts of unhealthy, calorically dense food than those with a higher education level, possibly because they are more physically active.

Clear association between ACE inhibitors, acute kidney injury Posted: 06 Nov 2013 05:22 PM PST New research shows clear association between ACE inhibitors -- drugs used to treat high blood pressure and heart disease -- and acute kidney injury. These and similar drugs are the second most prescribed on the National Health Services in England.

New study identifies signs of autism in the first months of life Posted: 06 Nov 2013 10:19 AM PST Researchers have identified signs of autism present in the first months of life. The researchers followed babies from birth until 3 years of age, using eye-tracking technology, to measure the way infants look at and respond to social cues. Infants later diagnosed with autism showed declining attention to the eyes of other people, from the age of 2 months onwards.

New explanation for infection susceptibility in newborns: It is all about helping beneficial bacteria colonize the gut Posted: 06 Nov 2013 10:19 AM PST Cells that allow helpful bacteria to safely colonize the intestines of newborn infants also suppress their immune systems to make them more vulnerable to infections, according to new research. The study could prompt a major shift in how medicine views the threat of neonatal infections -- and how researchers go about looking for new strategies to stop it, said scientists who conducted the study.

Discovery of HIV 'invisibility cloak' reveals new treatment opportunities Posted: 06 Nov 2013 10:19 AM PST Scientists have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural defense systems.

Don't get sick in July Posted: 06 Nov 2013 09:21 AM PST With almost no experience, newly graduated medical students enter teaching hospitals around the country every July, beginning their careers as interns. At the same time, the last year's interns and junior residents take a step up and assume new responsibilities. More experienced physicians share a joke about this changing of the guard: Don't get sick in July.

Postoperative pain may increase risk of temporary problems with learning, memory Posted: 06 Nov 2013 08:41 AM PST The pain caused by a surgical incision may contribute to the risk of postoperative cognitive dysfunction, a sometimes transient impairment in learning and memory that affects a small but significant number of patients in the days following a surgical procedure.

Prognostic value of baseline survival determined for 11 types of cancer Posted: 06 Nov 2013 08:40 AM PST Results of a study point out the prognostic value of baseline recorded health-related quality of life for survival for eleven types of cancer: brain, breast, colorectal, esophageal, head and neck, lung, melanoma, ovarian, pancreatic, prostate, and testicular cancer. For each cancer site, at least one health-related quality of life parameter provided additional prognostic information over and above the clinical and sociodemographic variables.

Reforms urgently needed to streamline road to Alzheimer's Posted: 06 Nov 2013 08:40 AM PST As the burden of Alzheimer's disease escalates worldwide, efforts to develop effective treatments are failing to keep pace because of the high costs and risks associated with developing Alzheimer's drugs.
