	Inflammatory bowel disease patients over the age of 60 often receive older drugs Inflammatory bowel disease is common amongst older people and there are big differences in the choice of treatment for different age groups. Patients over the age of 60 often receive cortisone drugs instead of more modern medicines that target the immune system.

	UA researchers receive grant to study effects of simulated space radiation on gastrointestinal tract The Center for Applied NanoBioscience and Medicine is doing its part to protect the health of astronauts on long-duration missions, including NASA's Journey to Mars.

			New health analysis in India finds increase in non-communicable diseases A new state-by-state health analysis in India finds that over two decades heart- and lung-related conditions, as well as other non-communicable diseases (NCDs), have surpassed infectious diseases, such as diarrhea and tuberculosis, as the nation's leading killers.

			Penn researchers single out bacterial enzyme behind gut microbiome imbalance linked to Crohn’s disease Penn Medicine researchers have singled out a bacterial enzyme behind an imbalance in the gut microbiome linked to Crohn's disease.

			Researcher awarded $1.5 million to study role of tumor necrosis factor in IBD D. Brent Polk, MD, AGAF, an investigator at Children's Hospital Los Angeles, has been awarded $1.5 million by the National Institute of Diabetes and Digestive and Kidney Diseases of the NIH for the study of tumor necrosis factor (TNF) and its role in inflammatory bowel disease (IBD).

	PPI use not linked to increased risk of developing dementia Proton pump inhibitors (PPIs) are medicines commonly prescribed to treat acid-related digestive problems, including gastroesophageal reflux disease (or GERD).

	Small Intestinal Bacterial Overgrowth (SIBO) Pathophysiology Small intestinal bacterial overgrowth (SIBO) is a pathological overgrowth of gut bacteria upwards or rather in a retrograde fashion, into the upper gastrointestinal tract. This has many consequences, which reflect upon both intestinal and extraintestinal homeostasis.

	Small Intestinal Bacterial Overgrowth (SIBO) Signs and Symptoms Small intestinal bacterial overgrowth (SIBO) is a condition in which there are an excessive number of bacteria in the small intestine. It is important as the cause of much gastrointestinal symptomatology, albeit non-specific, as well as systemic features, such as nutritional deficiencies, osteoporosis and significant asthenia. Diarrhea and malabsorption are frequently at the root of these complaints.

	Surgery for Piles Also referred to as hemorrhoids, piles are swollen veins inside the anal canal (internal hemorrhoids) or around the anus (external hemorrhoids). When anal or rectal tissue that has become swollen gets damaged, bleeding and pain may result.

	Risk Factors for Small Intestinal Bacterial Overgrowth Small intestinal bacterial overgrowth (SIBO) is a medical condition in which bacteria in the gut overgrow. This normally does not occur under good health conditions.

	Small Intestinal Bacterial Overgrowth (SIBO) Treatment Small intestinal bacterial overgrowth (SIBO) is a condition in which gut bacteria grow up into the proximal small intestine. It can cause many nonspecific, but distressing conditions, and may lead to malnutrition as well as mucosal inflammation and increased mucosal permeability, both of which exacerbate malabsorption and may cause systemic or local hypersensitivity reactions to various foods.

	Researchers reduce over-prescription of antibiotics by using computer alerts to inform doctors Physicians at Kaiser Permanente in Southern California reduced the odds of prescribing an antibiotic for sinusitis by 22 percent using computer alerts to inform doctors when antibiotics may not be the best course of treatment. The research was published today in the American Journal of Managed Care.

	Liver disease in children with Alagille Syndrome caused by malformations of bile ducts Serious liver and heart problems can affect children with Alagille Syndrome early in life. While there is as yet no cure, researchers at Karolinska Institutet in Sweden have discovered that the liver disease part of the syndrome is caused by specific malformations of the bile ducts.

	FDA approves first adjuvant treatment to reduce risk of kidney cancer recurrence The U.S. Food and Drug Administration today approved Sutent (sunitinib malate) for the adjuvant treatment of adult patients who are at a high risk of kidney cancer (renal cell carcinoma) returning after a kidney has been removed (nephrectomy).

	Women have lower tolerance to alcohol following gastric sleeve surgery, study finds Women who have had gastric sleeve surgery to lose weight may want to consider limiting the number of alcoholic drinks they consume post-surgery.

	WFIRM-led project aims to study health risks astronauts face from exposure to space radiation The Wake Forest Institute for Regenerative Medicine has been selected by NASA to lead a multi-institutional project to better understand the health risks astronauts face from the exposure to galactic cosmic ray (GCR) and solar energetic particle (SEP) radiation that occurs from long-duration missions in deep space, and to develop countermeasures to keep astronauts safe.

	Tulane professor wins Department of Defense grant for research into arteriovenous malformations Tulane University's Stryder Meadows, a cell and molecular biology professor, received a $1.7 million grant from the Department of Defense to study how arteriovenous malformations (AVM), which are defects in arteries, veins and capillaries, form Hereditary Hemorrhagic Telangiectasia (HHT), a genetic disorder that affects about 1 in 5,000 people.

	Genetic diversity of tumor tissues can be barrier to precision medicine in gastric and esophageal cancers A new study focused on describing genetic variations within a primary tumor, differences between the primary and a metastatic branch of that tumor, and additional diversity found in tumor DNA in the blood stream could help physicians make better treatment choices for patients with gastric and esophageal adenocarcinoma.

	MGH researchers identify first effective treatment option for autoimmune small-fiber polyneuropathy An analysis of the medical records of patients treated at Massachusetts General Hospital (MGH) for an often-mysterious condition involving damage to small nerve fibers supports the hypothesis that some cases are caused by autoimmune disease and also identifies the first effective treatment option.

	Research shows how food poisoning bacteria can multiply and spread inside micro-organisms New research by a team from London's Kingston University has shown how the food poisoning bacteria Campylobacter can multiply and spread inside micro-organisms called amoebae- which could lead to a better understanding of how bacteria survive and help efforts to prevent the spread of infection.
