Surgery for appendicitis is the most common emergency operation in children. A new study has found that the UK has the highest reported national rate of ‘normal appendicectomy,’ where children undergo surgery for suspected appendicitis but laboratory examination of the removed appendix finds it to be normal. Although most children who are misdiagnosed as having appendicitis improve without…
A study led by scientists from Cornell University provides important new insights into a common and deadly type of gastric cancer. Incidence of this cancer, called gastric squamous-columnar junction (SCJ) cancer, also known as gastroesophageal cancer, rose 2.5 times in the United States between the 1970s and 2000s, while cases of all gastric cancers have decreased by more than 80% since the…
In animals, a vaccine modifying the composition and function of the gut microbiota provides protection against the onset of chronic inflammatory bowel diseases and certain metabolic disorders, such as diabetes and obesity. This research was conducted by the team of Benoît Chassaing, Inserm researcher at Institut Cochin (Inserm/CNRS/Université de Paris), whose initial findings have been…
Researchers from the University of Helsinki developed a novel diagnostic method for the rapid on-site measurement of antibodies from patient samples. Now they have applied this new method for the diagnostics of celiac disease, with promising results. Point-of-care (POC) testing is a rapidly growing sector, bringing medical testing from central laboratories to where the patient is receiving care.…

Now, a 3D solution for gastroscopy and colonoscopy is available, by simply connecting a device to the hospital’s existing flexible endoscopy equipment with a 3D monitor. This solution is presented by MedicalTek (MDTK), a Taiwanese company specialized in the field of medical image…
Researchers at the University of Exeter first identified a gene in the 'hospital bug' Clostridioides difficile responsible for producing a protein that aids in binding the bacteria to the gut of its victims. In collaboration with researchers at Paris-SUD University, they then showed that mice vaccinated with this protein generated specific antibodies to the protein – and that C. diff that did…
Scientists have uncovered a novel antibiotic-free approach that could help prevent and treat one of the most widespread bacterial pathogens, using nanocapsules made of natural ingredients. Helicobacter pylori is a bacterial pathogen carried by 4.4 billion people worldwide, with the highest prevalence in Africa, Latin America and the Caribbean. Although the majority of infections show no symptoms,…
Genetic differences in the immune system shape the collections of bacteria that colonize the digestive system, according to new research by scientists at the University of Chicago. In carefully controlled experiments using germ-free mice populated with microbes from conventionally raised mice, the researchers showed that while the makeup of the microbial input largely determined the resulting…
A little bit of norovirus – the highly infectious microbe that causes about 20 million cases of food poisoning in the United States each year – goes a long way. Just 10 particles of the virus can cause illness in humans. A team of University of Arizona researchers has created a simple, portable and inexpensive method for detecting extremely low levels of norovirus. Jeong-Yeol Yoon, a…
Prebiotics are currently a preferred treatment for certain metabolic disorders, as they can restore the balance of dysfunctional gut microbiota, and improve the body’s metabolism. However, these substances have to be used at high doses, which can result in patients experiencing bloating and flatulence. A research group led by Matteo Serino, Inserm researcher at the Digestive Health Research…
More cancer, more cardiovascular disease: The relaxation of UK industry regulation of salt content in food was – to put it lightly – a very bad idea, say researchers from Imperial College London and the University of Liverpool. They have linked the change in regulation with 9,900 additional cases of cardiovascular disease (CVD), and 1,500 cases of stomach cancer. The researchers analysed the…
Patients with biliary tract cancer have altered genetic architecture in some immune system receptor systems. This has been shown by researchers at Karolinska Institutet in Sweden in a new study published in the journal Gastroenterology. It is hoped that the discovery will lead to new effective immunotherapy for these difficult to treat tumour types. Biliary tract cancers, including…
Changes in certain sections of the genetic material of cancer cells, so-called microsatellites, can provide an important indication of whether immunotherapy may be successful in a patient with stomach or colorectal cancer. Scientists from Uniklinik RWTH Aachen, the German Cancer Research Center (DKFZ), the German Cancer Consortium (DKTK) and the National Center for Tumor Diseases Heidelberg (NCT)…
While the onset of inflammatory bowel disease (ulcerative colitis or Crohn’s disease) in adulthood is tied to a higher mortality, the actual number of deaths has been falling, a Swedish study from Karolinska Institutet published in the journal Gut reports. Now it is a case of ascertaining which of the newer treatments are the most efficacious, say the researchers. Using the Swedish National…
A joint team from Hokkaido University and Keio University has identified a gut protein essential for neonatal mice to fight infections, according to research published in the Journal of Experimental Medicine. The insight could help understand how infants develop their own intestinal immune systems after weaning. The gut is constantly exposed to potentially harmful bacteria that come with food and…
Skype hypnotherapy is an effective treatment for people with severe irritable bowel syndrome, a new study has found. The study of 20 patients who had the treatment via the online communications tool was led by Professor Peter Whorwell from The University of Manchester It is published in the International Journal of Clinical and Experimental Hypnosis. Professor Whorwell is a gastroenterologist at…
The holiday season just wouldn't be the same without delicious Christmas cookies. Impatience in the bakery, however, might be penalized with some unpleasant or even dangerous side-effects. Bruce Ruck, managing director of the New Jersey Poison Control Center at Rutgers University Medical School, talks about the risks associated with eating raw cookie dough: “It’s a potential recipe for food…
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…
Obesity, cancers and other gastrointestinal diseases have digestive systems all over Europe in a chokehold. In a new report, non-profit organisation United European Gastroenterology (UEG) sheds a spotlight on the issues, challenges and inequalities of digestive health - and points out ways to fix the most pressing problems.
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…
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…
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.
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…
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…
