Finding the origins of angiosarcoma

In a new study published in the journal Nature Medicine on February 2020, scientists report some newly discovered reasons for the occurrence of a rare blood vessel wall cancer called angiosarcoma. This could one day help develop better therapies for this aggressive tumor. The project is a striking example of unexpectedly rich findings from a crowd-sourced venture that brings together a scattered group of patients with a rare disease.

Human textiles to replace damaged blood vessels

What if we could replace a patient's damaged blood vessels with brand new ones produced in a laboratory? This is the challenge set by Inserm researcher Nicolas L'Heureux, who is working on the human extracellular matrix - the structural support of human tissues that is found around practically all of the body's cells.

Viagra may cause long lasting visual disturbances finds study

In a new study scientists have reported that Sildenafil or Viagra pills used for erectile dysfunction could lead to longer lasting visual disturbances than known before. The study titled, “Ocular Side Effects of Sildenafil That Persist Beyond 24 h—A Case Series,” was published in the latest issue of the journal Frontiers in Neurology.

Increasing the number of small blood vessels may be helpful for recovering movement

Many health conditions - ranging from disease of particular organs such as heart and lungs, widespread metabolic issues such as diabetes, or following trauma such as spinal cord injury – cause difficulties with movement.

Improved breast reconstruction

Breast reconstruction after removal or mastectomy of the breast for cancer is a common procedure among breast cancer survivors. In a new development, surgeons have developed a process to map out the blood vessels in the tissues of the abdomen that would be used to reconstruct the breast, prior to the mastectomy.

Eating meat linked to poorer health

The seesaw continues with respect to the benefits of meat eating. The latest large new study published in February 2020 in the journal JAMA Internal Medicine reveals that eating red and processed meat is associated with a small but significantly higher risk of heart disease and death. Says researcher Norrina Allen, “It's a small difference, but it's worth trying to reduce red meat and processed meat like pepperoni, bologna and deli meats.”

Blood test can be used to gauge a person's risk for cerebral small vessel disease

A UCLA-led study has found that levels of six proteins in the blood can be used to gauge a person's risk for cerebral small vessel disease, or CSVD, a brain disease that affects an estimated 11 million older adults in the U.S. CSVD can lead to dementia and stroke, but currently it can only be diagnosed with an MRI scan of the brain.

Research identifies link between chronic kidney disease and heart failure

People with chronic kidney disease have a higher risk for heart disease and heart-disease death. Now, for the first time in humans, research led by Navkaranbir Bajaj, M.D., of the University of Alabama at Birmingham, has identified a pathological change that appears to link kidney disease to progressive heart disease.
