Research sheds new light on pancreatic cancer metastasis

With an overall survival rate of 9% for those diagnosed, pancreatic cancer remains exceedingly difficult to treat. However, the patient's primary tumor typically isn't what leads to death - it is the…

Potential trigger of Crohn’s disease found

Potentially game-changing research led by McMaster University scientists may finally bring relief to millions of people worldwide living with Crohn’s disease. Investigator Brian Coombes said his team identified a strain of adherent-invasive E-coli (AIEC) that is strongly implicated in the condition and is often found in the intestines of people with Crohn’s disease. “If you examine the gut…

Intrahepatic cholangiocarcinoma

A new approach for treating bile duct cancer

Intrahepatic cholangiocarcinoma (ICC) develops within the liver. With one to two cases per 100,000 inhabitants in Germany, ICC is one of the rare diseases overall, but it is the second most common liver cancer. The aggressive bile duct tumour remains clinically inconspicuous for a long time, so that it is often only detected late. Because the tumour also only responds to chemotherapy to a limited…

Capsule cameras to test for cancer and diseases

Miniature cameras which patients can swallow to get checked for cancer are being trialled across the NHS. The imaging technology, in a capsule no bigger than a pill, can provide a diagnosis within hours. Known as a colon capsule endoscopy, the cameras are the latest NHS innovation to help patients access cancer checks at home. Traditional endoscopies mean patients need to attend hospital and have…

'Organs-on-a-chip' system sheds light on interactions between gut and brain

In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals such as mice is difficult to do, because their…

Genome study reveals

Blood group affects composition of intestinal microbiome

For several years, scientists worldwide have been investigating the extent to which microorganisms living in and on the human body influence central life processes and thus health and disease. Today they assume that there is a connection between the totality of the microbial colonization in the human body, called the microbiome, and the development of diseases. Chronic inflammatory bowel disease…

New mechanism of cancer formation discovered

A team of scientists at the National University of Singapore (NUS) led by Dr Polly Leilei Chen from the Cancer Science Institute of Singapore and Yong Loo Lin School of Medicine has discovered a previously unknown mechanism of cancer formation, the understanding of which may lead to more effective treatment. Their findings concern a process called RNA editing. The DNA code of a gene gets…

Influence of gut bacteria

How our gut microbiome affects Covid-19 severity

The variety and volume of bacteria in the gut, known as the microbiome, may influence the severity of Covid-19 as well as the magnitude of the immune system response to the infection, suggests research published online in the journal Gut. Imbalances in the make-up of the microbiome may also be implicated in persisting inflammatory symptoms, dubbed ‘long Covid’, the findings suggest. Covid-19…

Connecting our microbiome to breast cancer development

A microbe found in the colon and commonly associated with the development of colitis and colon cancer also may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy. Breast tissue cells exposed to this toxin retain a long-term memory, increasing the…

Ensuring Patient Safety in Endoscopy

Patient safety in endoscopy must be approached from a holistic perspective, through solutions which increase detection rates of abnormalities, increase confidence in the safety of the reprocessing outcome, and control the risk of infection and cross-contamination. With these important benefits in mind, manufacturers should be continuously working to innovate products to establish solutions that…

Gut microbiome: Crohn’s disease bacteria grown in the lab

Several thousand strains of bacteria live in the human gut. Some of these are associated with disease, while others have beneficial effects on human health. Figuring out the precise role of each of these bacteria can be difficult, because many of them can’t be grown in lab studies using human tissue. This difficulty is especially pronounced for species that cannot live in oxygen-rich…

‘Pill on a string’ test could transform oesophageal cancer diagnosis

A ‘pill on a string’ test can identify ten times more people with Barrett’s oesophagus than the usual GP route, a new study shows. The test, which can be carried out by a nurse in a GP surgery, is also better at picking up abnormal cells and potentially early-stage cancer. Barrett’s oesophagus is a condition that can lead to oesophageal cancer in a small number of people. It’s usually…

IBD: The late repercussions of early antibiotics use

Disruption of gut bacteria by antibiotics soon after birth can affect the maturation of the immune system, say researchers at Rutgers University-New Brunswick. Even short, single antibiotic courses given to young animals can predispose them to inflammatory bowel disease (IBD) when they are older, according to their research. The study, published in Genome Medicine, provides further evidence…

Improved grading system to predict esophageal cancer survival

A group of researchers led by Osaka University established a new pathological grading system to evaluate the therapeutic effect of neoadjuvant chemotherapy (NAC) for metastatic lymph nodes (LNs) removed in esophageal cancer (EC) surgery, demonstrating that the system predicts recurrence and prognosis in EC patients better than conventional systems. Their research results were published in Annals…

Gut flora could hold the key for new diabetes treatments

An organic compound produced by the gut flora – the metabolite 4-Cresol – is considered to have protective effects against both type 1 and 2 diabetes, notably by stimulating the growth of the insulin-producing pancreatic beta cells. This is according to a new study led by Inserm researcher Dominique Gauguier at the Environmental Toxicology, Therapeutic Targets, Cell Signaling and Biomarkers…
