High-fat diet can cause pancreatic cancer – but there's hope

A high-fat diet may promote the growth of pancreatic cancer independent of obesity because of the interaction between dietary fat and cholecystokinin (CCK), a digestive hormone. In addition, blocking CCK may help prevent the spread of pancreatic tumors to other areas of the body (metastases). The new findings are published ahead of print in the American Journal of Physiology—Gastrointestinal…

MAIT cells sense metabolic state of enteric bacteria

A little-explored group of immune cells plays an important role in the regulation of intestinal bacteria. Changing metabolic states of the microbes have an effect on defense cells at different stages of alert or rest, as researchers from the Department of Biomedicine at the University and University Hospital of Basel report in the journal "Mucosal Immunology." It is known that the…

Helicobacter creates immune system blind spot

While gastritis and gastric ulcer disease used to be put down to stress and dietary factors, it was discovered in the 1980s that the actual culprit is infection with a bacterium, H. pylori. This pathogen is now classed as a type I carcinogen by the WHO, as it is the major risk factor for development of gastric carcinoma. Attempts to develop a vaccine against H. pylori have been unsuccessful and…

Can a colonoscopy cause appendicitis?

Although the incidence of appendicitis in the United States has been in decline for many years, the condition still affects approximately seven percent of Americans annually. A research team at the UND School of Medicine and Health Sciences, found that there is evidence to suggest that a colonoscopy can “prompt” appendicitis up to one week after the procedure, in at least certain patients.

Tracing the evolution of E. coli

Bacteria are stealthy organisms. They can multiply in minutes and evolve to survive what we throw at them—including antibiotics. The World Health Organization calls antibiotic resistance “one of the biggest threats to global health, food security, and development today.” Each year, about 2 million people in the United States become infected with antibiotic-resistant bacteria, according to…

Single blood test screens for 8 cancer types

Johns Hopkins Kimmel Cancer Center researchers developed a single blood test that screens for eight common cancer types and helps identify the location of the cancer. The test, called CancerSEEK, is a unique noninvasive, multianalyte test that simultaneously evaluates levels of eight cancer proteins and the presence of cancer gene mutations from circulating DNA in the blood. The test is aimed at…

Experts' discussion

How to tackle parasitic worms

Parasitic worm infections – or helminthiases – affect more than one billion people and have a considerable public health impact in many parts of the world. In December 2017, international experts gather in Basel, Switzerland, to discuss new strategies to control and eliminate parasitic worms. The scientific symposium is hosted by the Swiss Tropical and Public Health Institute. Approximately…

Do common acid reflux medications promote chronic liver disease?

Approximately 10 percent of the general population take a proton pump inhibitor (PPI) drug to block stomach acid secretions and relieve symptoms of frequent heartburn, acid reflux and gastroesophageal reflux disease. That percentage can be as much as seven times higher for people with chronic liver disease. Researchers at University of California San Diego School of Medicine have discovered…

Dieting does not help autistic kids with GI trouble

Many children with autism spectrum disorder experience significant gastrointestinal issues, but the cause of these symptoms is unknown. Professionals in the medical community have suggested a potential link between diet and gastrointestinal issues related to autism. Now, researchers from the University of Missouri School of Medicine have found that diet is not a contributing factor in these…

3D viewing benefits gastroenterology

During many and various 2015 medical congresses 3-D visualisation has been a key topic as the industry continues to introduce improved hardware and software in ever-shorter intervals. Interventional medicine is entering a new dimension, was a popular slogan. The crystal clear, coloured visualisation of body cavities previously only visible in cloudy black and white may be fascinating, but it does…

The role of the microbiota in preventing allergies

The human body is inhabited by billions of symbiotic bacteria, carrying a diversity that is unique to each individual. The microbiota is involved in many mechanisms, including digestion, vitamin synthesis and host defense. It is well established that a loss of bacterial symbionts promotes the development of allergies. Scientists at Helmholtz Zentrum Munich, at the Technical University of Munich…
