Swarms of nanoparticles which are 15,000 times smaller than a pinhead may be able to deliver vital drugs to the brain, offering new hope to patients in the early stages of a stroke. The research, carried out at The University of Manchester, shows that tiny vesicles called liposomes, just 100 nanometres in diameter can translocate through the damaged blood brain barrier following stroke. And that…
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.
Blood clotting is one of the most critical, protective processes in human physiology. When something goes wrong with clotting, either because there is too much clotting, leading to a stroke, or not enough, leading to internal bleeding, the outcome can be catastrophic. Now, University at Buffalo researchers have established an in vitro model of this process that will help clinicians improve…
It appears that an influenza vaccine does not just work when it comes to influenza. A new study shows that elderly people who have been admitted to an intensive care units have less risk of dying and of suffering a blood clot or bleeding in the brain if they have been vaccinated. And this is despite the fact that they are typically older, have more chronic diseases and take more medicine then…
Biotronik announces the market release of its new injectable cardiac monitor (ICM), Biomonitor III, following approval in the CE region. The novel device is designed to help patients with irregular heart rhythms by documenting suspected arrhythmia or unexplained syncope with increased clarity. As the most common type of arrhythmia, 33.5 million patients worldwide suffer from atrial fibrillation…
Cheap and compact instrument based on two near-infrared light techniques diagnoses poor blood flow quickly and noninvasively.
Researchers at The Ohio State University College of Medicine and The Ohio State University Wexner Medical Center have developed a novel stroke therapy that, when tested in mice and dogs, has proven superior to the standard of care therapy now offered to patients suffering a stroke. Findings of the study are published online in Molecular Therapy. “We have shown that our drug, which is completely…
Half of patients prescribed statins in primary care fail to reach ‘healthy’ cholesterol levels after two years of treatment with these drugs, reveals research published online in the journal Heart. The findings back up those of previous studies, and highlight the need for personalised medicine to tackle high cholesterol and lower the significantly increased risks of future heart disease and…
Researchers at Karolinska Institutet have found that type IgG antibodies play an unexpected role in atherosclerosis. A study on mice shows that the antibodies stabilise the plaque that accumulates on the artery walls, which reduces the risk of it rupturing and causing a blood clot. It is hoped that the results, which are published in the journal Circulation, will eventually lead to improved…
Cancel the cheese omelet. There is sobering news for egg lovers who have been happily gobbling up their favorite breakfast since the 2015-2020 Dietary Guidelines for Americans no longer limited how much dietary cholesterol or how many eggs they could eat. A large, new Northwestern Medicine study reports adults who ate more eggs and dietary cholesterol had a significantly higher risk of…
A day case catheter ablation procedure which includes only the bare essentials and delivers the same outcomes could slash waiting lists for atrial fibrillation patients, according to late-breaking results from the AVATAR-AF trial presented today at EHRA 2019, a European Society of Cardiology (ESC) congress. With the simplified protocol, 30% more patients could receive catheter ablation for the…
Atrial fibrillation can be correctly detected using commercially available smartwatches. This is the conclusion of a study by researchers of the German Centre for Cardiovascular Research (DZHK) at the University Medicine Greifswald and researchers from the Basel University Hospital.
White matter on the brain is a difficult subject. Even the terminology is varied, making differential diagnosis complex. An understanding of prevalence and of the tools available to facilitate the diagnosis of individual diseases is important, Dr Gunther Fesl, radiologist at Praxis Radiologie Augsburg, explains.
A new analysis from University College London, King's and the University of Manchester finds an extra 69 lives are being saved every year as a result of further centralisation of services in Greater Manchester. In London, where earlier research had shown that centralising acute stroke services saved an extra 96 extra lives per year, these improvements have been sustained over time.
Obstetricians and midwives often warn new mothers about postpartum depression. They might mention what symptoms women should look out for—such as crying spells or extreme irritability—and where they can turn for help. But people who have strokes may not learn that they, too, are at risk for depression. Post-stroke depression stems from the cardiovascular changes in the brain that lead to a…
Portland State University (PSU) researchers have made a significant breakthrough by developing the 3-D structure of proteins from inside the eye lens that control how cells communicate with each other, which could open the door to treating diseases such as cataracts, stroke and cancer. The PSU research team, led by chemistry professor Steve Reichow, used a multimillion-dollar microscope and a…
A collaborative study led by a neurologist at Rush University Medical Center and an environmental scientist at the University of Illinois at Chicago suggests that weather patterns that cause dramatic changes in barometric pressure may increase the incidence of a type of stroke known as spontaneous intracerebral hemorrhage, that is, the rupture of a blood vessel in the brain. The researchers…
For patients who take medication to treat hypothyroidism, being treated with too much medication can lead to an increased risk of atrial fibrillation, a common heart rhythm disorder associated with stroke, a new study of more than 174,000 patients has found. The findings were presented by researchers from the Intermountain Medical Center Heart Institute in Salt Lake City at the American Heart…
Here at Medica, the Taiwanese start-up Maisense is demonstrating Freescan, its artificial intelligence (AI) based solution to screen for stroke through the early detection of atrial fibrillation (AFib). Speaking of the system’s aims, Maisense summed up this huge health problem. ‘Every four minutes, someone dies of stroke. Thirteen percent of these are classified as haemorrhagic stroke. When…
One in two women and one in three men will likely be diagnosed with dementia, Parkinson's disease, or stroke in their lifetime, estimate Dutch researchers in an observational study
When delegates from around 150 countries converge on Munich for ESC Congress 2018 they will no doubt reflect on what they themselves eat. Yes, nutrition is up for debate, questioning, for example, whether weight loss therapies can also prevent heart attacks and strokes. Results from the CAMELLIA-TIMI 61 trial of 12,000 overweight individuals with established cardiovascular disease or diabetes…
New research, published in the European Heart Journal, has shown deaths from conditions that affect the blood supply to the brain, such as stroke, are declining overall in Europe but that in some countries the decline is levelling off or death rates are even increasing. Cerebrovascular disease includes strokes, mini-strokes, and narrowing, blockage or rupturing of the blood vessels supplying…
Neurologist who coined the phrase "Time is Brain" says message is not so simple anymore. Rather there should be no hard-and-fast rule governing when therapy can be given because strokes progress differently in different patients.
New research shows that for the vast majority of individuals, sodium consumption does not increase health risks except for those who eat more than five grams a day, the equivalent of 2.5 teaspoons of salt. Fewer than five per cent of individuals in developed countries exceed that level. The large, international study also shows that even for those individuals there is good news. However, the…
Transgender individuals may be at higher risk for myocardial infarction and death due to cardiovascular disease, according to several studies. This increased risk may be due to the hormone therapy that transgender patients take for masculinization or feminization. A review authored by Michael S. Irwig, MD, associate professor of medicine at the George Washington University (GW) School of Medicine…
