A study of nearly 108,000 people has found that people who regularly drink a modest amount of alcohol are at increased risk of atrial fibrillation, a condition where the heart beats in an abnormal rhythm. The study, published in the European Heart Journal, found that, compared to drinking no alcohol at all, just one alcoholic drink a day was linked to a 16% increased risk of atrial fibrillation…
Researchers at the University of Chicago have created the first usable computational model of the entire virus responsible for Covid-19—and they are making this model widely available to help advance research during the pandemic. “If you can understand how a virus works, that’s the first step towards stopping it,” said Prof. Gregory Voth, whose team created the model published in…
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…
In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study, which was published in Immunity, may contribute to future treatments for Covid-19, among other diseases.
So far, little research has been done on the risk of children being seriously affected by Covid-19 when the schools were open. A study from Karolinska Institutet has now shown that one child in 130,000 was treated in an intensive care unit on account of Covid-19 during the period March-June. The study has been published in New England Journal of Medicine.
Non-degradable prostheses for cardiovascular tissues can be used to replace heart valves and blood vessels, but they can’t stay in the body permanently. In two recent papers, researchers at the Eindhoven University of Technology (TU/e) in collaboration with a number of clinical partners, the Dutch Heart Foundation, and TU/e spin-off companies Suprapolix, Xeltis, and STENTiT have shown how…
Before the pandemic, the lab of Stanford University biochemist Peter S. Kim focused on developing vaccines for HIV, Ebola and pandemic influenza. But, within days of closing their campus lab space as part of Covid-19 precautions, they turned their attention to a vaccine for SARS-CoV-2, the virus that causes Covid-19. Although the coronavirus was outside the lab’s specific area of expertise,…
Patients with acute heart failure nearly double their risk of dying if they get Covid-19, according to new research. The small, single centre study highlights the need for patients with heart failure to take extra precautions to avoid catching Covid-19. “Our results support prioritising heart failure patients for Covid-19 vaccination once it is available,” said study lead investigator Dr.…
Brain metastases can only develop if cancer cells first exit the fine blood vessels and enter into the brain tissue. To facilitate this step, cancer cells influence blood clotting, as scientists from the German Cancer Research Center and Heidelberg University Hospital have now been able to show in mice. The cancer cells actively promote the formation of clots, which helps them to arrest in the…
All prediabetes is not the same: in people in the preliminary stages of type 2 diabetes, there are six clearly distinguishable subtypes, which differ in the development of the disease, diabetes risk, and the development of secondary diseases. This is shown in a study by the Institute for Diabetes Research and Metabolic Diseases (IDM) of Helmholtz Zentrum München at the University of Tübingen,…
Reports from Imperial College regarding the spread and the effects of Covid-19 had considerable policy impacts in several European countries. But the models that informed the reports have considerable flaws, and are not sufficient to draw the conclusions that were published. This is according to researchers from universities including Linköping University (LiU), in an article in Nature.
Research conducted at the Health New Orleans Neuroscience Center of Excellence at the Louisiana State University (LSU) reports that a combination of an LSU Health-patented drug and selected DHA derivatives is more effective in protecting brain cells and increasing recovery after stroke than a single drug. The findings are published in Brain Circulation.
The identification of people wearing masks has often presented a unique challenge during the pandemic. A new study by researchers from BGU and York University in Canada reveals the impact of this predicament and its potentially significant repercussions. The findings were just published in the journal Scientific Reports.
Colon cancer stem cells have one weak spot: the enzyme Mll1. An MDC team led by Walter Birchmeier has now shown in Nature Communications that blocking this protein prevents the development of new tumors in the body. Since colonoscopies were introduced in Germany for early cancer detection, the number of diagnoses of advanced cancer every year has decreased, as precancerous lesions can now be…
Cold Spring Harbor Laboratory (CSHL) scientists have discovered a gene-regulating snippet of RNA that may contribute to the spread of many breast cancers. In animal experiments, the researchers could reduce the growth of metastatic tumors with a molecule designed to target that RNA and trigger its destruction. The same strategy, they say, could be used to develop a new breast cancer treatment for…
A recent review study concludes that nanoplastics change the composition and diversity of gut microbiome in vertebrates and invertebrates. The effects of a widespread and prolonged exposure to nanoplastics observed in animal models can be applied to humans.
A new method for visualizing breath that is exhaled while someone is speaking or singing could provide important new insights into how diseases such as Covid-19 spread and the effectiveness of face masks. “Scientists believe the SARS-CoV-2 virus is primarily spread through respiratory droplets that can be carried in the breath or expelled through coughing or sneezing,” said Thomas Moore from…
Scientists from Würzburg and the US have charted the first global atlas of direct interactions between SARS-CoV-2 RNA and human host cells. This may provide a starting point for novel treatments. SARS-CoV-2 infections pose a global threat to human health and a formidable research challenge. One of the most urgent tasks is to gain a detailed understanding of the molecular interactions between the…
Patterns of brain activity can be used to forecast seizure risk in epilepsy patients several days in advance, according to a new analysis of data obtained from clinically approved brain implants by neuroscientists at UC San Francisco, the University of Bern and the University of Geneva.
Nearly twice as many people were admitted to hospital for Covid-19 at the height of the pandemic than were for influenza at the peak of the 2018/2019 flu season, a study of French national data published in The Lancet Respiratory Medicine journal has found (Covid-19, 89,530 patients vs influenza, 45,819 patients).
Like all viruses, the novel coronavirus is dependent on help from the human host cell. Proteins are the functional units of the cell and enable the virus to enter the host cell or help the virus to replicate. Scientists from Charité – Universitätsmedizin Berlin and from the Berlin Institute of Health (BIH), along with colleagues from the United Kingdom, Germany and the United States, have…
Researchers have discovered that microglia cells constantly survey the brain to prevent spontaneous seizures.
The type and abundance of bacteria found in the mouth may be linked to lung cancer risk in non-smokers, finds the first study of its kind, published online in the journal Thorax.
Scientists at Heriot-Watt University have developed a technique that monitors a patient’s vital signs completely touch free. By using a continuous wave radar-based system to sense tiny chest movements, the new method can accurately measure an individual’s heart rate and respiratory rate without the need for wires, probes, wearable technology or other skin attachments. It could also identify…
A new class of epidemiological models based on alternative thinking about how contagions propagate, particularly in the early phases of a pandemic, provide a blueprint for more accurate epidemic modeling and improved disease spread predictions and responses, according to a study published recently in Scientific Reports by researchers at the University of California, Irvine and other institutions.
