First independent test of proposed subphenotypes of COVID-19-related ARDS

In a new paper published online in the Annals of the American Thoracic Society, researchers have been unable to produce two theorized subphenotypes of COVID-19 related acute respiratory distress syndrome (ARDS).

Disordered gut microbiomes are found in patients with hemorrhagic brain disease

A new study shows that people with a rare genetic disease that causes bleeding in the brain have gut microbiomes distinct from those without the disease.

Blood clotting disorders may explain some of the worst symptoms of COVID-19

The hypothesis that blood clotting disorders may explain some of the worst symptoms of COVID-19, including respiratory failure and pulmonary fibrosis, was suggested in mid-April by researchers in Brazil affiliated with the University of São Paulo's Medical School (FM-USP) via an article accepted for publication by the Journal of Thrombosis.

UZH researchers develop new X-ray contrast agent for high-resolution vascular imaging

Various diseases in humans and animals - such as tumors, strokes or chronic kidney disease - damage the blood vessels. Capillaries, the smallest blood vessels in the body, are particularly affected.

New technique offers high-resolution 3D view inside tumors

Malignant tumors consume nutrients and oxygen faster than healthy cells. To do so, they recruit blood vessels in their environment. Depending on tumor type and genetic profile, there are differences on how tumors look internally.

Novel stimulation pattern helps relieve chronic pain

The vagus nerve plays an important role in our body. It consists of various fibres, some of which connect to the internal organs, but the vagus nerve can also be found in the ear. It is of great importance for various body functions, including the perception of pain.

The eye initiates an immune response in the lens after injury

The lens of the eye is an unusual organ. Unlike most of the body's organs, blood vessels don't reach the lens. If they did, they'd obscure our vision and we wouldn't be able to see.

Inherited genetic variations can alter progression of melanoma, indicates study

Sometimes cancer stays put, but often it metastasizes, spreading to new locations in the body. It has long been suspected that genetic mutations arising inside tumor cells drive this potentially devastating turn of events.

Children with COVID-19 presenting with sudden severe lung disease

Even as the COVID-19 pandemic continues to seek out new victims, puzzling new presentations are further confusing the situation. A new study published online in The Lancet Rheumatology in May 2020 reports a case of severe COVID-19 in a child who rapidly developed acute respiratory distress symptoms without prior respiratory symptoms. This case should alert clinicians to consider this diagnosis in children as well.

Capillary leakage important in COVID-19 respiratory distress

Now, a new study published on the preprint server medRxiv reports the pivotal role played by protein leakage through lung capillaries and promotes the use of serum albumin as a biomarker of disease progression and severity.

Teens develop septic shock due to COVID-19

Since the emergence of the novel coronavirus disease (COVID-19), most people who develop severe illness are older adults, those with underlying medical conditions, and those who are immunocompromised. Though children are mostly spared, some adolescents developed septic shock due to COVID-19, a new study has found.

Study finds evidence of injury in placentas from COVID-19-positive pregnant women

The placentas from 16 women who tested positive for COVID-19 while pregnant showed evidence of injury, according to pathological exams completed directly following birth, reports a new Northwestern Medicine study.

Study evaluates the effectiveness of interferon beta 1b in COVID-19 pneumonia

As the world struggles to overcome the current COVID-19 pandemic with non-pharmacological interventions, in the absence of an effective drug or vaccine, existing immunomodulators are being repurposed. A new study published on the preprint server medRxiv* in May 2020 shows no clinical benefit to the use of one such drug, called interferon beta 1b (IFN beta1b).

New cooling insole helps reduce risk factor for diabetic foot ulcers

A new cooling insole developed by UT Southwestern scientists reduced the foot temperature of patients with diabetic neuropathy by several degrees, diminishing a significant risk factor for diabetic foot ulcers.

Adding an array of spices to a meal may help reduce inflammation

Adding an array of spices to your meal is a surefire way to make it more tasty, but new Penn State research suggests it may increase its health benefits, as well.

Researchers report a new way to stabilize liposomes

For decades, scientists have explored the use of liposomes –– hollow spheres made of lipid bilayers –– to deliver chemotherapy drugs to tumor cells.

New mathematical model to study the behavior of the human heart

Having now reached its third year, Project "iHEART" of Politecnico di Milano, winner of an ERC Advanced Grant of euro 2,350,000, has set itself the ambitious goal of creating a complete mathematical model to study the behavior of the human heart and of its pathologies, a sort of "virtual microscope."

New drug treatment can reduce risk of death from COVID-19 infection

Researchers in the Ludwig Center at the Johns Hopkins Kimmel Cancer Center report they have identified a drug treatment that could--if given early enough--potentially reduce the risk of death from the most serious complication of Coronavirus disease 2019 (COVID-19), also known as SARS-CoV-2 infection.

Texas A&M lab produces 3D-bioprinted bone tissue to benefit bone regeneration

Dr. Akhilesh K. Gaharwar, associate professor, has developed a highly printable bioink as a platform to generate anatomical-scale functional tissues. This study was recently published in the American Chemical Society's Applied Materials and Interfaces.

Synchrotron X-ray imaging reveals more about Ménière's disease

The organ of balance in the inner ear is surrounded by the hardest bone in the body. Using synchrotron X-rays, researchers at Uppsala University have discovered a drainage system that may be assumed to play a major role in the onset of Ménière's disease, a common and troublesome disorder.
