Developing AI algorithms for earlier glioblastoma detection

Novel advanced imaging biomarkers are being developed in a series of studies at several UK centres that may lead to the earlier assessment of treatment response to glioblastoma (GBM) and a better survival rate. Through a number of clinical trials – and the application of artificial intelligence (AI) to retrospective data sets – the aim is to highlight approaches that will enable clinicians to…

Potentials and pitfalls for IB development

Imaging biomarkers: Close surveillance is mandatory

Imaging biomarkers (IB) have advanced tremendously since first described 25 years ago, but many challenges still block their widespread use. During the EuSoMII’s annual meeting in Valencia, Dr Ángel Alberich-Bayarri gave pragmatic solutions to tackle current bottlenecks and explained why close surveillance is mandatory for further development of IB. However, these need close surveillance with…

Lack of sleep might throw off Alzheimer’s test

A preliminary study has found that when young, healthy men were deprived of just one night of sleep, they had higher levels of tau, a biomarker for Alzheimer’s disease, in their blood than when they had a full, uninterrupted night of rest. The study is published in the January 8, 2020, online issue of Neurology, the medical journal of the American Academy of Neurology. Tau is a protein found in…

Simple blood test for early detection of breast cancer

Breast cancer could be detected up to five years before there are any clinical signs of it, using a blood test that identifies the body’s immune response to substances produced by tumour cells, according to new research presented at the 2019 NCRI Cancer Conference. Cancer cells produce proteins called antigens that trigger the body to make antibodies against them – autoantibodies. Researchers…

Respiratory failure and sepsis

Cheap, quick test identifies major risks for pneumonia patients

Spanish researchers in Valencia have identified specific fragments of genetic material that play a role in the development of respiratory failure and sepsis in pneumonia patients. Presenting the research at the European Respiratory Society International Congress, Dr Francisco Sanz said the findings could enable doctors to test quickly for these biological markers when a patient is admitted to…

Biomarker

A real-time MRI method for the early detection of stroke

An international research group at the Max Planck Institute for Biological Cybernetics developed a brain imaging method for improved and early assessment of stroke. Their study presents a methodology which monitors calcium ion fluctuations in the brain using a molecular functional MRI approach.

Fat radiomic profile

Using AI to predict heart attacks

Technology developed using artificial intelligence (AI) could identify people at high risk of a fatal heart attack at least five years before it strikes, according to new research funded by the British Heart Foundation (BHF). The findings are being presented at the European Society of Cardiology (ESC) Congress in Paris and published in the European Heart Journal. Researchers at the University of…

Methylation of microRNA

Is it cancer? New method could tell the difference

Levels of molecules associated with genetic function, such as microRNA, can be an important indicator of abnormal activity associated with cancer. However, little is known about how different molecules are altered in cancerous cells. Now, researchers from Japan have found a new way of distinguishing cancerous from non-cancerous tissues. In a study published in Nature Communications, researchers…

Mortality risk

A new biomarker to predict your lifespan?

Fourteen metabolic biomarkers can predict long term mortality in individuals helping to determine life expectancy in general populations, a new study in the journal Nature Communications reports. In the largest study of its kind, researchers from Leiden University Medical Center in the Netherlands and the University of Surrey investigated predictors of long-term mortality risk. Current predictors…

Brain activity may help predict success of CBT in depression

In a new study, led by the University of Glasgow, scientists show that brain activity recorded using functional magnetic resonance imaging (fMRI) may help predict response to CBT in depression before the treatment commences. The advances could help patients receive the most appropriate treatment for depression in a timely manner.

Cornea restoration: Scientists develop physical biomarker

Our eyes – considered by many to be the windows to the soul – need constant care, and as we age, they sometimes also need significant repair. The panes of these windows – the corneas – are transparent tissues that have been the focus of some of the oldest and most common transplantation surgeries. Now thanks to researchers in Kyoto, some such transplants may become even safer. The team,…

Artificial Intelligence

Allying AI to biomarkers is powerful but validation remains challenging

Using artificial intelligence (AI) to push development of imaging biomarkers shows great promise to improve disease understanding. This alliance could be a game changer in healthcare but, to advance research, clinical validation and variability of results must be factored in, a prominent Spanish radiologist advises. In clinical practice efforts are already ongoing to apply AI to obtain new…

Flow cytometry

Living cells – the essential biomarker

The team of the Heinz Nixdorf Chair of Biomedical Electronics at the Technical University of Munich focuses on innovative diagnostic tools to accelerate the development towards personalized medicine. Therapies tailored to the individual patient – this is the future not only of oncology but of many medical disciplines. “At this point, however,” concedes Professor Dr Oliver Hayden,…

Improvement of cardiac care

Rapid myocardial infarction verification

The use of troponin assays to rule in or rule out myocardial infarction (MI) rapidly is critical on several levels. The quick result can reassure the patient that they have not had a heart attack and can return home safely; or, in the event of MI, the relevant treatment can start very soon. It also ensures that clinicians can make the right decision with confidence. Troponin levels have been the…

Making the invisible visible

New method opens unexplored realms for liquid biopsies

Advancing technology is allowing scientists increasingly to search for tiny signs of cancer and other health issues in samples of patients’ blood and urine. These “liquid biopsies” are less invasive than a traditional biopsy, and can provide information about what’s happening throughout the body instead of just at a single site. Now researchers at the University of Michigan Rogel Cancer…

Post-cancer impairment

'Chemobrain': New biomarkers found

Cognitive impairment associated with cancer, also known as “chemobrain”, has gained recognition as a complication of the disease and its treatment, as it can negatively affect the daily lives of cancer patients and survivors. Chemobrain can be subtle yet persistent, with some cancer patients reporting difficulties related to memory and attention even months after completing their treatment.…

Finding the 'fingerprint' of cardiovascular disease

Forty-two percent of all deaths in the United States are related to cardiovascular disease (CVD). According to the Global Cardiovascular Drugs Market Forecast, by 2030 the number of deaths from CVD will rise to 23.6 million per year in the U.S. alone. Along with increased deaths, spending on drugs to treat CVD as well as related hospital stays, home health care and lost productivity will also…

Flow cytometry rises to new challenges

Flow cytometry has proved an invaluable diagnostic tool for leukaemia and lymphoma for almost three decades. Now, however, this is evolving in applications to seek out residual disease in cases and in fusion with molecular testing to advance its diagnostic potential. However, although recognised as fast, flexible and accurate, flow cytometry suffers from a lack of standardisation, according to…

The enormous potential of liquid biopsy

It is non-invasive, delivers a chance of early diagnosis, prognostic information and sequential monitoring, and, believes Professor Francesco Salvatore, the enormous potential of liquid biopsies has still to be reached. However, the positive results obtained so far have ‘opened the door to a promising new multi-faceted group of tumour markers, at present collectively designated “liquid…
