Signaling defects could cause congenital heart condition

A congenital heart condition known as left ventricular non-compaction (LVNC) - which occurs when muscly projections in the embryonic heart fail to transform into compact heart muscle - could be caused by signaling defects, according to new preclinical research led by Duke-NUS Medical School in Singapore.

Retinal macular damage linked to sleep apnea in diabetes

A new Taiwanese study presented on October 14, 2019, at the Annual Meeting of the American Academy of Ophthalmology, reports that macular edema in diabetes occurs more often in those who have severe sleep apnea.

AI detects over 95 percent of diabetic retinopathy cases

A new study presented at the Annual Meeting of the American Academy of Ophthalmologists (AAO) on October 14, 2019 reports an astonishing 95.% yield when artificial intelligence (AI) is used to screen a real life population for diabetic retinopathy.

Widely available drug could reduce deaths in traumatic brain injury patients, major study shows

A low cost and widely available drug could reduce deaths in traumatic brain injury patients by as much as 20%, depending on the severity of injury, according to a major study published in The Lancet.

Study: More aggressive blood pressure control can improve brain health in older adults

A major UConn School of Medicine study published in the American Heart Association's flagship journal Circulation shows that more aggressively controlling daily blood pressure in older adults can improve brain health.

Study: Automated AI screening system accurately detects diabetic retinopathy 95.5% of the time

New research shows that an automated, artificial intelligence (AI) screening system accurately detects diabetic retinopathy 95.5 percent of the time.

Sleep apnea is a risk factor for developing diabetic macular edema, study shows

New research from Taiwan shows that severe sleep apnea is a risk factor for developing diabetic macular edema, a complication of diabetes that can cause vision loss or blindness. Diabetic macular edema was also more difficult to treat in patients with severe sleep apnea.

Rapid and sensitive tracking of fat molecules in the body

Fats have earned a bad name as the source of all that is wrong with our hearts and blood vessels, not to mention our appearance. The dysfunctional handling of lipids or fats in the body is deeply involved in a multitude of metabolic upsets, such as obesity and cancer.

New study blames vascular rather than nerve injury for concussion

Brain concussion occurs when the soft cottage cheese-like brain tissue is slammed against the hard skull surface, sustaining transient and reversible injury which causes brain dysfunction for a period.

Study shows microbleeds after head injury signal danger to brain function

A new study published in the journal Brain shows that microbleeds appearing after trauma can cause patients with head injury to have poor outcomes. Advanced imaging techniques were used to establish this finding.

Signs of aging detected by a simple walking test at age 45

A new study has shown that the speed at which persons over 45 years of age walk could be an indicator of their brain and body age. The team of researchers from Duke University found that persons who walked slowly were more likely to have “accelerated aging” compared to those who walked faster.

New study could change the way traumatic brain injuries are treated

Traumatic brain injuries, including concussions, can be caused by anything from sports injuries to battlefield trauma.

SOX9 broadly modifies the severity of Alagille syndrome liver disease in mice

Alagille syndrome is a rare pediatric genetic disorder that can affect the liver, heart, kidneys, blood vessels, skeleton and other tissues.

Imaging tumor stiffness could aid delivery of treatment to most challenging cancers

Using a non-invasive imaging technique that measures the stiffness of tissues gives crucial new information about cancer architecture and could aid the delivery of treatment to the most challenging tumors, new research shows.

Blood test can improve diagnosis and monitoring of aortic aneurysms

It is the 'silent killer' that claimed the life of Albert Einstein and affects 1% of men over the age of 65, but researchers at the University of Dundee believe they may be able to reduce the number of fatalities caused by abdominal aortic aneurysms.

New gene therapy for wet age-related macular degeneration is on the horizon

Gene therapy is showing promise for one of the most common causes of blindness. Data presented today shows that six patients with wet age-related macular degeneration have, so far, gone at least six months without the need for continued injections to control a disease that typically requires treatment every four to six weeks.

New microneedle insulin pill avoids injections, applies insulin to gut wall

Quite a few drugs such as insulin are made up of protein and hence can’t be taken internally, as the gut breaks them down, rendering them useless. Thus these have to be administered by injection, and in the case of drugs that have to be taken several times a day this is a definite limitation.

Cell discovery could help fight against liver disease

Scientists have identified new sub-types of cells that, when they interact, accelerate the scarring process in diseased livers.

Dysfunctions in blood vessels contribute to the development of chronic inflammatory bowel diseases

In Germany alone there are around 400,000 patients who suffer from chronic inflammatory bowel diseases. For the first time, researchers at Universitätsklinikum Erlangen have discovered that dysfunctions in blood vessels play a significant role in the development of such diseases.

New understanding of breast cancer metastasis to bone

In breast cancer patients with metastatic disease, bone is the most common site of metastasis and the most common site of first distant relapse, with roughly half (48%) of breast cancer patients developing bone metastases after treatment.
