Brain mechanisms behind compulsive behaviors in Parkinson's disease patients

New research unravels the brain mechanisms that underlie the ability of a standard drug treatment for Parkinson's to elicit compulsive behaviors in some patients with the disease. The study, published by Cell Press in the January 14th issue of the journal Neuron, provides fascinating new insight into the brain mechanisms that underlie a predisposition to behavioral addictions, such as pathological gambling and shopping.

Researchers identify new gene variants associated With glucose, insulin levels

A major international study with leadership from Massachusetts General Hospital (MGH) researchers has identified 10 new gene variants associated with blood sugar or insulin levels. Two of these novel variants and three that earlier studies associated with glucose levels were also found to increase the risk of type 2 diabetes. Along with a related study from members of the same research consortium, associating additional genetic variants with the metabolic response to a sugary meal, the report will appear in Nature Genetics and has been released online.

Research article addressing incidental findings in MRI-enterography in patients with CD to be published

MRI is increasingly used in the assessment of small bowel CD. Unlike conventional radiology, MRI enables visualization of disease extension beyond the intestinal wall, i.e., abscesses and fistulas. However, some extra-intestinal findings are unexpected and without relation to CD.

Early diagnosis can cure endometrial cancer

Postmenopausal women who experience vaginal bleeding should see a doctor promptly. According to the January issue of Mayo Clinic Health Letter, vaginal bleeding is a symptom that occurs early in the course of endometrial cancer, when the chance of a complete cure is the greatest. Even one drop of blood is abnormal in postmenopausal women.

More research needed to determine kidney and renal artery abnormalities, says study

Abnormalities in the kidneys and their blood vessels occur in at least 25% of healthy individuals, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). While most of these conditions are not harmful enough to prevent someone from donating a kidney, future studies are needed to determine their impact on long-term health.

CT-guided biopsy: An alternative method for patients with pancreatic masses

It is reasonable to obtain a histological diagnosis before treating patients who have pancreatic masses and are unsuitable or unwilling to undergo surgery. As the pancreas is a deep seated organ surrounded by other vital structures, it is a challenge for the physician to obtain an adequate specimen for histological examination.
