Among more than 35,000 postmenopausal women surveyed about supplement use, regular fish oil users had a 32 percent lower risk of breast cancer. The reduction appeared limited to invasive ductal breast cancer; other specialty supplements showed no link.

Scientists Find Culprits that Cause Celiac Disease
Researchers at Melbourne's Walter and Eliza Hall Institute say they have identified the specific gluten fragments that trigger celiac disease, after more than 200 patients ate bread, rye muffins or barley and gave blood tested against thousands of fragments.
Obesity
Meat Linked to Obesity
An American Journal of Clinical Nutrition study followed some 374,000 adults in nine European countries for five years and found 250 grams of meat a day tracked with about 2 kg of weight gain. Red meat, poultry and processed meat all showed positive associations.
Cancer
FDA to Determine Avastin's Fate
An FDA oncology panel meets July 20 to weigh whether Avastin keeps its breast cancer indication. The 2008 study behind its accelerated approval showed 5.5 extra months before the disease worsened; later research put the gain at 1 to 2.9 months.
Diabetes
Red meat linked to higher risk of diabetes
Across 75,512 adults in Hawaii followed a mean 14 years, men eating the most red meat were 43 percent more likely to develop diabetes and women 30 percent. For processed red meat the increases were 57 and 45 percent. Fresh poultry showed no link to diabetes risk.
Obesity
Mental Acumen Linked to Body Shape
Northwestern researchers analysing 8,745 postmenopausal women aged 65 to 79 found pear-shaped women, carrying fat around the hips, had more cognitive difficulty than apple-shaped women, and that each one-point rise in BMI matched a one-point drop on a 100-point memory test.
Obesity
Baby's Obesity Risk: What's Mom's Influence?
ARS researcher Kartik Shankar is studying whether a mother's own overweight can permanently alter how her child regulates weight. In his rat work, pups of overweight dams weighed normally at birth but gained markedly more once given unlimited high-fat rations after weaning.
Other Diseases
Less is More When Restraining Calories Boosts Immunity
Forty-six overweight adults aged 20 to 40 followed a 30-percent or 10-percent calorie-restricted diet for six months. Both groups significantly increased their delayed-type hypersensitivity response and T-cell proliferation, markers of cell-mediated immunity, ARS-funded researchers found.
Heart & Blood
MRI: New Gold Standard in Diagnosing Stroke
New American Academy of Neurology guidelines say doctors should use a diffusion MRI rather than a CT scan to diagnose acute ischemic stroke within 12 hours of the first symptom. In one large study reviewed, MRI detected stroke 83 percent of the time against 26 percent for CT.
Heart & Blood
Sleep Apnea Increases Heart Disease Risk
Researchers followed 1,927 men and 2,495 women aged 40 and over who had no heart disease at their baseline sleep study. After eight and a half years they concluded obstructive sleep apnea is associated with higher risk of heart failure in men; the coronary heart disease link was equivocal.
Other Diseases
Link Found Between Obesity Gene and Alzheimer's
A Karolinska Institute study of 1,000 Swedes aged 75 and older links a variant of the obesity-related FTO gene to a 58% higher risk of Alzheimer's and a 48% higher risk of other dementias, apparently independent of diabetes and obesity. The researchers stress more research is needed.
Other Diseases
Tea and Physical Activity Reduce Dementia Risk
Studies presented at the Alzheimer's Association conference in Honolulu tied dementia risk to vitamin D, tea and exercise: people with insufficient vitamin D were 42 percent more likely to develop dementia, and drinking tea one to four times a week was linked to 37 percent lower risk.
Obesity
FDA_to_Review_Weight_Loss_Drugs
The FDA starts reviewing Qnexa, with lorcaserin due in September and Contrave in December. Qnexa, a phentermine-topiramate combination, cut body weight 13 to 15% in trials but had the highest dropout rate over memory and concentration problems. Lorcaserin had fewest side effects and least effect.
Cancer
HPV and Skin Cancer: Facts and Figures
Dartmouth's Margaret Karagas found that testing positive for two or three strains of HPV was associated with a 44 percent higher risk of squamous cell carcinoma, while stressing the link may not be causal. The study compared 663 patients with SCC, 898 with basal cell carcinoma and 805 controls.
Autoimmune Diseases
Renaissance Research in AIDS Prevention
NIAID-led researchers identified two human antibodies that neutralized more than 90 percent of HIV strains in the laboratory, against 30 to 40 percent for the best antibodies found earlier, and showed how they work. The technique could be applied to other infectious diseases.
Obesity
Childhood Obesity Could Lead to GERD, Cancer
Researchers pulled records for 690,321 patients aged 2 to 19 in an integrated health plan and found childhood obesity associated with gastroesophageal reflux disease, a link the authors say may carry risk of further conditions such as esophageal cancer.
Other Diseases
Malaria Drug not Recommended for Leg Cramps
The FDA reviewed adverse event reports from 2005 to 2008 and concluded that Qualaquin, approved to treat malaria, should not be given for leg cramps because its active ingredient, quinine, puts patients at risk of serious blood disorders.
Cancer
Enhanced Milieu Key to Cancer Survival
Ohio State researchers found mice housed in large cages with 18 to 22 others, toys and running wheels developed tumors later and had lesions 43 percent smaller than mice in standard cages. The enriched mice also showed a 90 percent drop in leptin.
