Protein appears to prevent tumor cells from spreading via blood vessels

Johns Hopkins researchers describe protein regulating key step in cancer metastasis

2021-07-12

(Press-News.org) Researchers have identified a specialized protein that appears to help prevent tumor cells from entering the bloodstream and spreading to other parts of the body.

"We have discovered that this protein, TRPM7, senses the pressure of fluid flowing in the circulation and stops the cells from spreading through the vascular system," said Kaustav Bera, a Johns Hopkins University PhD candidate in chemical and biomolecular engineering and a lead author of the study, which was done with colleagues at the University of Alberta and Universitat Pompeu Fabra.

"We found that metastatic tumor cells have markedly reduced levels of this sensor protein, and that is why they efficiently enter into the circulation rather than turning away from fluid flow," said Bera.

Monitoring proves better than active treatment for low-risk prostate cancer

2021-07-12

Men over 60 with low-risk prostate cancer could spend ten years with no active treatment, have a better sex life as a result, yet still be very unlikely to die from the disease, new research has found. The findings come from two new studies looking at 'active surveillance' of prostate cancer - when the disease is closely monitored but not treated - presented at the European Association of Urology congress, EAU21, today. The first uses data from Sweden's National Prostate Cancer Register, which has information on virtually every man diagnosed with the disease in that country since 1998 - 23,649 of whom went on active surveillance. ...

Care home residents are at risk of COVID-19 even after being fully vaccinated

2021-07-12

Care homes need to be vigilant for outbreaks of COVID-19, even after residents have received two doses of the vaccine, according to new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) held online this year. Long-term care facilities, such as care homes with elderly residents with multiple underlying conditions, are at high risk of COVID-19 outbreaks and many vaccination campaigns have initially focused on care home residents and the staff looking after them. An outbreak in a French care home, however, raises questions about how effective the vaccine is in the elderly. Martin Martinot, of ...

Outbreaks of COVID-19 in French nursing homes traced back to staff

2021-07-12

COVID-19 outbreaks in French nursing homes almost certainly started in staff - and none of measures put in place stopped the virus from taking hold, new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), held online this year, shows. Residents of long-term care facilities represent a small fraction of the general population but account for a disproportionate number of SARS-CoV-2-related deaths in many countries. In France, 5,203 outbreaks (of 1 case or more) were reported in nursing homes during the first wave of COVID-19. In the Auvergne-Rhône-Alpes region, there were 651 outbreaks, 3,885 residents had confirmed COVID-19 infection and 1,772 ...

Flu jab protects against some of the severe effects of COVID-19, including

2021-07-12

The flu vaccine may provide vital protection against COVID-19, new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), held online this year, concludes. An analysis of patient data from around the world strongly suggests that the annual flu shot reduces the risk of stroke, sepsis and DVT in patients with COVID-19. Patients with COVID-19 who had been vaccinated against flu were also less likely to visit the emergency department and be admitted to the intensive care unit (ICU). Immunising the world against COVID-19 is a daunting challenge and, although production and distribution of vaccines increases daily, some countries are not expected to vaccinate large numbers of their population ...

Hepatitis C vaccine could be rolled out within five years, says Nobel Prize winner who discovered virus

2021-07-12

A vaccine to protect against infection with hepatitis C could be in use within 5 years, says Professor Sir Michael Houghton, who won the Nobel Prize for Medicine and Physiology along with three other scientists for discovering the hepatitis C virus (HCV) in 1989. Sir Michael will discuss the development of a vaccine in a special presentation at this year's European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), held online this year. Up to 2 million new HCV infections occur every year around the world, with an estimated 70 million carriers of the virus globally, most of whom are not diagnosed. The virus is estimated to cause some 400,000 deaths annually. Many infected with the virus go on to develop liver cirrhosis and liver cancer. "While the advent of ...

High-tech toilets could spread antibiotic-resistant superbugs in hospitals, Japanese study suggests

2021-07-12

Water-jet nozzles in electric toilets--commonly used in Japan and other parts of Asia--may be reservoirs for multidrug-resistant Pseudomonas aeruginosa (MDRP) in hospitals, increasing the risk of dangerous germ transmission among patients, according to new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) held online this year. "This is the first report of hospital transmissions associated with electric toilets and could have major implications for infection control," says Dr Itaru Nakamura from Tokyo Medical University Hospital ...

New study shows that silver foil could reduce the risk of infection in hospitals

2021-07-12

New research presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) taking place online (9-12 July) shows that covering high-touch (the most regularly touched) surfaces in hospitals with silver-impregnated foil could significantly reduce levels of contamination by clinically important bacterial pathogens. The study by Professor Andreas Widmer and colleagues at the University Hospital Basel, Basel, Switzerland, evaluated the antimicrobial effectiveness of a polyvinyl chloride (PVC) foil containing an integrated silver-based agent containing 2% silver ions. The hospital environment has increasingly been recognised as having critical importance when formulating infection control measures ...

Obesity increases survival in advanced prostate cancer

2021-07-11

Obese patients with a form of advanced prostate cancer survive longer than overweight and normal weight patients, new research has found. The study, presented today at the European Association of Urology congress, EAU21, followed more than 1500 patients over three years. Patients classed as obese - with a BMI over 30 - had a ten percent higher survival rate than thinner patients over 36 months. Although obesity is usually associated with an increased risk of death from many cancers and some other chronic diseases, there is some evidence in a few cancers of a survival advantage for patients with high body mass index. ...

Beautiful VR setting could reduce pain in unpleasant medical procedure

2021-07-11

Being immersed in a stunning 'virtual' Icelandic landscape can reduce the pain caused by uncomfortable medical procedures, new research has found. The study compared patients with and without virtual reality (VR) headsets having rigid cystoscopies, where a rigid telescope is inserted through the urethra into the bladder. The research is being presented today at the European Association of Urology congress, EAU21. Diagnosing and treating bladder cancer usually requires checking the bladder through a cystoscopy, which is perceived by patients as unpleasant and painful. Some patients avoid follow-up and as a result suffer uncontrolled and irreversible development of the disease. It is possible to have a flexible cystoscopy, which is less painful, ...

New concept drug hunts down late-stage prostate cancer

2021-07-11

A new class of drug successfully targets treatment-resistant prostate cancers and prolongs the life of patients. The treatment delivers beta radiation directly to tumour cells, is well tolerated by patients and keeps them alive for longer than standard care, found a phase 3 trial to be presented at the European Association of Urology congress, EAU21, today. Despite progress in medicine in recent years, metastatic castration-resistant prostate cancer remains untreatable and fatal. The new treatment, known as Lu-PSMA-617, takes a new approach, targeting a molecule called PSMA, which is known to be increased on the surfaces of the tumour cells, destroying them and their surrounding microenvironment. Professor Johann de Bono, Professor of Experimental Cancer Medicine at The ...
