Preventive anti-clotting therapy does not boost survival of critically ill COVID patients
Although abnormal blood clotting has been identified as one of the primary causes of death from COVID-19, early treatment in an intensive care unit with therapeutic anticoagulation (anti-clotting) for adults who are critically ill with COVID-19 does not appear to improve chances of survival, and could do more harm than good by increasing the risk for major bleeding, a multicenter research group cautions. (2021-02-03)

Subset of COVID-19 patients have increased bleeding risk
A new potential biomarker raises concerns over the current standard for treating COVID-19 induced blood clots with high dose blood thinners. (2021-02-01)

Study identifies noncoding RNA involved in immune response and sepsis
When the body's immune response to an infection gets out of control, the result can be sepsis, a life-threatening condition in which an overwhelming inflammatory response can lead rapidly to failure of multiple organs and death. In a new study, researchers at UC Santa Cruz have identified a long noncoding RNA (lncRNA) molecule that regulates the expression of pro-inflammatory genes in immune system cells called macrophages and affects the susceptibility of mice to septic shock. (2021-02-01)

Latest review shows intensive care mortality from COVID-19 continued to fall in 2020, but improvement is slowing
A meta-analysis of global studies published in Anaesthesia (a journal of the Association of Anaesthetists) shows that intensive care morality from COVID-19 has continued to fall since the start of the pandemic, but the improvement is slowing and may have plateaued. (2021-02-01)

NUS scientists discover a new pathway essential for blood formation
Scientists from the National University of Singapore have discovered how a protein called Tip60 plays a vital role in the renewal of blood cells in the body.

The research results have just been published in the prestigious scientific journal Science Advances. (2021-01-26)

New study: Malaria tricks the brain's defence system
Malaria is one of the most common causes of death in children in Africa. When the parasite builds up in the blood vessels of the brain, it develops into one of the most dangerous forms of the disease, cerebral malaria. Though it wasn't certain if the parasite was able to penetrate the brain tissue, now researchers from the University of Copenhagen have found parasites can do that and have mapped the mechanism they utilise. (2021-01-26)

Anticoagulants reduce the number of brain metastases in mice
Brain metastases can only develop if cancer cells exit the capillaries and enter into the brain tissue. To facilitate this step, cancer cells influence blood clotting, as Heidelberg scientists have now been able to show in mice. The cancer cells actively promote the formation of clots, which helps them to arrest in the brain capillaries and then penetrate through the vessel wall. Drugs that inhibit thrombin were able to reduce the number of brain metastases. (2021-01-05)

UC researcher urges caution using remdesivir to treat COVID-19
Research at the University of Cincinnati, however, contends that this antiviral drug is being used too indiscriminately when treating patients hospitalized with the virus. The study is published in the journal Fundamental & Clinical Pharmacology. (2020-12-29)

A full blood count of COVID-19 patients can predict disease severity
International research led by the Radboud university medical center shows that a full blood count of COVID-19 patients predicts fairly accurately whether the infection will have a complicated course or not. This makes it easier for healthcare providers to estimate the expected clinical picture. This study, conducted in eleven hospitals, has now been published in the scientific journal eLife. (2020-12-21)

Fibrous proteins such as collagen and fibrinogen form a thin solid layer on the surface of an aqueous solution similar to the 'skin' that forms on warm milk, according to a team of Penn State Researchers, who believe this finding could lead to more efficient bioprinting and tissue engineering. (2020-12-17)

COVID-19 patients at higher risk of death, health problems than those with flu
A deep dive into federal data by researchers at Washington University School of Medicine in St. Louis reveals a clearer distinction between COVID-19 and the flu: Among hospitalized patients, COVID-19 was associated with an increased need for ventilators, more admissions into intensive care units, longer hospital stays and nearly five times the risk of death than faced by those with the flu. (2020-12-15)

Study shows endothelial cell targeting could help fight Covid-19 symptoms
For Covid-19 patients with serious lung disease, targeting endothelial cells -cells that comprise the blood vessel wall which regulate oxygen exchange between airways and the bloodstream- may be a novel approach restoring normal lung function. (2020-12-14)

Using light, red blood cells and a honey bee peptide to deliver therapeutic proteins
Protein therapies are often more potent and selective toward their biochemical targets than other types of drugs, particularly small molecules. However, proteins are also more likely to be quickly degraded by enzymes or cleared from blood by the kidneys, which has limited their clinical use. Now, researchers reporting in ACS Central Science have engineered red blood cell (RBC) carriers that release therapeutic proteins when stimulated by light, with the help of a honey bee peptide. (2020-12-09)

New method to boost supply of life-saving stem cells
Researchers at the Centre for Genomic Regulation (CRG) in Barcelona and Columbia University in New York City have found a new method for growing a large quantity of life-saving blood stem cells.

Researchers at Children's Hospital of Philadelphia (CHOP) have found elevated levels of a biomarker related to blood vessel damage in children with SARS-CoV-2 infection, even if the children had minimal or no symptoms of COVID-19. They also found that a high proportion of children with SARS-CoV-2 infection met clinical and diagnostic criteria for thrombotic microangiopathy (TMA). (2020-12-08)

New study debunks blood type diet
A study published in the Journal of the Academy of Nutrition and Dietetics by researchers with the Physicians Committee for Responsible Medicine -- a nonprofit of 12,000 doctors -- debunks the 'blood type diet' by finding that blood type was not associated with the effects of a plant-based diet on body weight, body fat, plasma lipid concentrations, or glycemic control. (2020-12-04)

Researchers from the University of Copenhagen and biotech firm Gubra have developed a new insulin molecule that will make blood sugar regulation both easier and safer for those with type 1 diabetes. (2020-12-03)

Marine mammals' adaptations to low oxygen offer new perspective on COVID-19
When Terrie Williams began hearing about the wide range of symptoms experienced by patients with COVID-19, she saw a connection between the various ways the disease is affecting people and the many physiological adaptations that have enabled marine mammals to tolerate low oxygen levels during dives. In a new review article, Williams explores how the diving physiology of marine mammals can help us understand the effects of COVID-19. (2020-12-03)

Differences in immunity and blood vessels likely protect children from severe COVID-19

Survival protein may prevent collateral damage during cancer therapy
Australian researchers have identified a protein that could protect the kidneys from 'bystander' damage caused by cancer therapies. The 'cell survival protein', called BCL-XL, was required in laboratory models to keep kidney cells alive and functioning during exposure to chemotherapy or radiotherapy. Kidney damage is a common side effect of these widely used cancer therapies, and the discovery has shed light on how this damage occurs at the molecular level. (2020-11-25)

Study: COVID-19 infection combined with blood clots worsen patient outcomes
While respiratory issues continue to be the most common symptom of a COVID-19 infection, new research indicates the disease could also be associated with an increased tendency of the blood to clot, leading to a higher risk of death from COVID-19. (2020-11-23)
