A microRNA that can be found in a blood sample may make it easier to detect gastric cancer and could lead to improved treatment for the disease and others like it that are resistant to common immunotherapies.
Researchers at the University of Cincinnati have identified new clues into ways tobacco use impacts patients with kidney cancer.
Bacteria in the small intestine can deaminate levodopa, the main drug that is used to treat Parkinson's disease. Bacterial processing of the unabsorbed fractions of the drug results in a metabolite that reduces gut motility. These findings were described in the journal BMC Biology on 20 October by scientists from the University of Groningen. Since the disease is already associated with constipation, processing of the drug by gut bacteria may worsen gastrointestinal complications.
Linked color imaging (LCI), a new image-enhanced endoscopy technique that allows users to recognize slight differences in mucosal color, is more effective than conventional white light imaging (WLI) for detecting tumors in the upper gastrointestinal tract. Findings from a randomized controlled trial are published in Annals of Internal Medicine.
According to an article in ARRS' American Journal of Roentgenology (AJR), secondary interpretations of body MRI at tertiary care centers identify a high rate of discrepancies--with primary errors being interpretive in origin--suggesting that subspecialty interpretations should be encouraged, and institutions should provide adequate resources for these interpretations to occur.
A group of three gene variants, commonly inherited together, may provide clues to more successful treatment of pediatric eosinophilic esophagitis (EoE), a chronic inflammation of the food pipe often confused with gastroesophageal reflux disease (GERD). A new study, led by researchers from Nemours Children's Health System and published in Clinical Gastroenterology and Hepatology, identifies genetic variants that help predict which children with EoE may not respond to proton pump inhibitor (PPI) medication therapy as a long-term solution.
A rectangular robot as tiny as a few human hairs can travel throughout a colon by doing back flips, Purdue University engineers have demonstrated in live animal models.
Nearly 1 in 8 commercially insured patients nationwide who underwent an elective colonoscopy between 2012 and 2017 performed by an in-network provider received potential 'surprise' bills for out-of-network expenses, often totaling hundreds of dollars or more. These findings are concerning, as federal regulations eliminate consumer cost-sharing when screening colonoscopies are performed in-network. A brief research report is published in Annals of Internal Medicine.
The study, presented today at UEG Week 2020 Virtual, analysed 1,435,350 patients with concurrent diabetes and obesity over a 20-year period. A total of 10,620 patients within the study had undergone bariatric surgery, an operation that helps patients lose weight by making changes to the digestive system.
Those with IBS at 16 were almost twice as likely to have had asthma at the age of 12 (11.2% vs 6.7%). Almost half of children with IBS at 16 (40.7%) reported food hypersensitivity at 12 years (compared to 29.2% of children without IBS at 16).
