Though the coronavirus disease COVID-19 so far appears to be largely sparing children, researchers are cautioning that it is critical to understand how the virus affects kids to model the pandemic accurately, limit the disease’s spread and ensure the youngest patients get the care they need. The warning comes from Steven L. Zeichner, MD, PhD, the head of UVA Health’s Division of Pediatric…
Media reporting of suicide, especially celebrity suicides, is associated with increases in suicide in the general population, particularly by the same method as used by the celebrity, finds an analysis of the latest evidence published by The BMJ. The researchers say their findings support the continued use and promotion of guidelines on responsible media reporting of suicide, especially when…
As coronavirus disease COVID-19 continues to jet and alight invisibly around the globe, scientists now report that the virus has mutated to become two strains: the older ‘S-type’ appears milder and less infectious, while the later-emerging ‘L-type’, is more aggressive, spreads more quickly, and currently accounts for about 70 per cent of cases. Worldwide, medical researchers are exploring…
An international team of researchers from the University of Zurich, the University Hospital Zurich, Heidelberg and Glasgow has identified a novel function for the cell death regulating protein MCL1: It is essential in protecting the intestine against cancer development – independent of bacterial-driven inflammation. These findings have implications for the use of MCL1 inhibitors, currently…
Pain researchers around the world have agreed to classify pain in the mouth, jaw and face according to the same system; according to a Danish participant, this means more precise diagnoses and improved treatment.
How long can coronavirus persist on surfaces such as door handles or hospital nightstands? How can the virus be destroyed effectively? A research team from Greifswald and Bochum, Germany, collected the answers scientists can currently offer to these and other pertinent questions and published them in the Journal of Hospital Infection.
Re-using clinical data for research is an academic and organisational challenge, but there is much to gain from this to advance healthcare. During the January Triangle leadership meeting in Madrid, Dr Xavier Pastor, CMIO at Hospital Clínic – Universitat de Barcelona, explained how his institution developed one of Spain’s first programs to promote real world data use in research projects.…
Could the ability of cancer cells to quickly alter their genome be used as a weapon against malignant tumours? Researchers at Uppsala University have succeeded in developing a substance that has demonstrated promising results in experiments on both animal models and human cancer cells. The study is published in the journal Nature Communications.
Unnecessary prostate cancer biopsies could be reduced by 60 per cent thanks to new research from the University of East Anglia (UEA). Researchers have developed new methods to identify biomarkers for prostate cancer by combining information from multiple parts of urine samples. It is hoped that the breakthrough could help large numbers of men avoid an unnecessary initial biopsy.
A growth hormone called insulin-like growth factor-1 (IGF-1) is likely to play a role in the development of breast cancer, according to new research published in the leading cancer journal Annals of Oncology. IGF-1 is already known to encourage the growth and proliferation of cancer cells. Now, two analyses of information from several hundred thousand women enrolled in the UK Biobank study have…
The University of Basel is part of the global search for a drug to fight the rampant coronavirus SARS-CoV-2. Researchers in the Computational Pharmacy group have so far virtually tested almost 700 million substances, targeting a specific site on the virus – with the aim of inhibiting its multiplication.
A population of stem cells with the ability to generate new bone has been newly discovered by a group of researchers at the University of Connecticut (UConn) School of Dental Medicine. In the journal Stem Cells, lead investigator Dr. Ivo Kalajzic, professor of reconstructive sciences, postdoctoral fellows Dr. Sierra Root and Dr. Natalie Wee, and collaborators at Harvard, Maine Medical Research…
Scientists from the German Cancer Research Center (DKFZ) and the Hebrew University in Jerusalem demonstrated in mice that intestinal bacteria reprogram DNA activity in cells of the gut mucosa and thus have a considerable impact on the development of the healthy gut.
Non-alcoholic fatty liver disease (NAFLD) is mostly diagnosed in overweight and obese people. However, severe forms of NAFLD can also be detected in rare genetic diseases such as lipodystrophy or in patients with HIV, putting them at a high risk for developing liver failure, diabetes and cardiovascular diseases. Norbert Stefan and colleagues have now detected a yet unknown cause of NAFLD in lean…
Artificial intelligence (AI) has the potential to improve efficiencies and precision in sleep medicine, resulting in more patient-centered care and better outcomes, according to a new position statement from the American Academy of Sleep Medicine. Published in the Journal of Clinical Sleep Medicine, the position statement was developed by the AASM’s Artificial Intelligence in Sleep Medicine…
Biomedical researchers in Munich have isolated immune cells from human tonsils obtained following routine surgery, and used them to analyze aspects of the immune response and test the effects of anti-inflammatory agents at the cellular level. Human tissues that have been surgically removed from patients are normally treated as waste, especially when they are derived from a ‘dispensable’ organ…
Celiac disease affects 0.3-2.4% of people in most countries world-wide, and approx. 2% in Finland. Celiac patients suffer from a variety of symptoms, typically intestinal complaints, such as diarrhea, but are often symptom-free. Immunologist Tobias Freitag co-developed and tested nanoparticles containing gliadin for the immunomodulatory treatment of celiac disease in Professor Seppo Meri’s…
If chromosomes are unevenly distributed or otherwise altered during cell division, this normally damages the daughter cells and impairs their viability. Not in cancer cells, however, in which chromosome instability can actually confer a growth advantage under certain circumstances. Moreover, as scientists from the German Cancer Research Center have now demonstrated in mice, changes in the…
A University of British Columbia (UBC) researcher is part of an international team working with a biotechnology company on a pilot clinical trial of a potential new treatment for patients with severe coronavirus infections in China. Dr. Josef Penninger, director of UBC’s Life Sciences Institute and Canada 150 Chair in Functional Genetics, is working closely with Vienna-based Apeiron Biologics…
People who have been treated in intensive care commonly suffer from residual cognitive impairment, but the reason for this is unknown. Researchers at Karolinska Institutet now link cognitive impairment with lasting inflammation and a potential treatment target. The results are presented in the scientific journal Intensive Care Medicine.
Cancer cachexia often occurs in cancer patients in an advanced state. This metabolic wasting syndrome leads to severely reduced muscle mass and fat tissue, which cannot be reversed by nutritional support. Furthermore, muscle regeneration is affected during cancer cachexia due to impaired muscle stem cell function. A problem that also occurs often in the aging process. Cancer cachexia is…
Researchers identified a group of small molecules that may open the door to developing new therapies for Duchenne muscular dystrophy (DMD), an as-yet-uncured disease that results in devastating muscle weakening and loss. The molecules tested by the team from the Perelman School of Medicine at the University of Pennsylvania eased repression of a specific gene, utrophin, in mouse muscle cells,…
There has been an increase in deaths and disability due to chronic respiratory (lung) diseases over the past three decades, finds an analysis of data from 195 countries published by The BMJ. The poorest regions of the world had the greatest disease burden. Ageing and risk factors including smoking, environmental pollution, and body weight also play a key role, say the researchers. Chronic…
A protein that helps colorectal cancer cells spread to other parts of the body could be an effective treatment target, researchers from Hokkaido University discovered. Colorectal cancer patients with an immune system-regulating protein called interleukin 6 (IL-6) are more likely to have recurring tumors that can also spread to the liver, according to research published in the journal Cancer…
