Cancer patients taking statin medication has lower risk of suffering a stroke

Cancer patients taking cholesterol-lowering statin medication following radiation therapy of the chest, neck or head had significantly reduced risk of suffering a stroke, and possibly other cardiovascular complications, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Scientists pinpoint cause of fatal respiratory disorder that turns babies' lips and skin blue

Scientists used a gene editing method called CRISPR/Cas9 to generate mice that faithfully mimic a fatal respiratory disorder in newborn infants that turns their lips and skin blue. The new laboratory model allowed researchers to pinpoint the ailment's cause and develop a potential and desperately needed nanoparticle-based treatment.

Healthy blood vessels could help stave off cognitive decline

High blood pressure may affect conditions such as Alzheimer’s disease by interfering with the brain’s waste management system, according to new research in rats published in JNeurosci. Maintaining blood vessel health could therefore help stave off cognitive decline.

Study uncovers potential new way to prevent common pregnancy-related complications

About 1 in 10 pregnant women experience placenta abnormalities that lead to life-threatening preeclampsia (hypertension), preterm labor and fetal growth problems, but finding effective treatments to effectively prevent or reverse these conditions has so far been elusive.

Passive cavitation imaging can estimate a drug’s dose and location in the brain

An ultrasound imaging technique called passive cavitation imaging was able to create an image and estimate the amount of a drug that crossed the blood-brain barrier to reach a specific location in the brain, according to a study by NIBIB-funded bioengineers at Washington University.

One-fifth of U.S. surgeons still 'overusing' riskier method to create kidney dialysis access, study finds

Long-term hemodialysis is a lifesaver for approximately half a million patients in the United States with kidney failure (also known as end-stage renal disease, or ESRD) who are either waiting on or unsuitable for a kidney transplant.

New implant technology safely minimizes injections for people with macular degeneration

In a clinical trial of 220 people with “wet” age-related macular degeneration, Johns Hopkins Medicine researchers, collaborators from many sites across the country, and Genentech in South San Francisco have added to evidence that using a new implant technology that continuously delivers medication into the eyes is safe and effective in helping maintain vision and reduces the need for injections in the eyes.

FAU scientists develop rapid, reliable method to continuously monitor sickle cell disease

Sickle cell disease is a hereditary disorder that affects red blood cells, distorting their natural disc shape into a crescent moon or "sickle" shape. Normal red blood cells move freely through small vessels throughout the body to deliver oxygen.

Study finds lower risk of Type 1 diabetes in children vaccinated against 'stomach flu' virus

Vaccinating babies against a virus that causes childhood "stomach flu" greatly reduces their chance of getting so sick that they need hospital care, a new study shows.

More screening and new treatments needed for sickle cell disease

The promise of new treatments for sickle cell disease, a group of inherited red blood cell disorders, has never been so great, but it will only be realized if there is constant investment in health policies such as programs for screening newborns, especially in sub-Saharan Africa, where most cases occur.

UAMS-developed noninvasive device detects melanoma in earliest stages

A University of Arkansas for Medical Sciences research team led by Vladimir Zharov, Ph.D., D.Sc., has demonstrated the ability to detect and kill circulating tumor cells in the blood using a noninvasive device called Cytophone that integrates a laser, ultrasound and phone technologies.

Saunas induce as much physical strain as moderate exercise

Most people assume that their blood pressure falls after a sauna, which is why this is often thought of as relaxing. This may be true in the long-term, but during the sauna session itself, surprisingly, the blood pressure rises just as if you were having a short moderately strenuous workout, according to a new study. This increases the workload on the heart.

Fibrinogen a key player in health and disease, says new study

A new study from the University of Alberta demonstrated that the blood clotting protein called fibrinogen also regulates MMP-2, an enzyme involved in immunity and in clot formation inside blood vessels. Prolonged MMP-2 inhibition could potentially produce a deficiency state with severe consequences.

UIC researchers describe role of unique pressure-sensing protein in lung edema

Researchers at the University of Illinois at Chicago describe for the first time the role of a unique, pressure-sensing protein in the development of lung edema -- a condition in which chronic high vascular pressure in the lungs causes fluid from the bloodstream to enter the air spaces of the lungs.

Researchers identify macrophages' pathway to nurture PTEN-deficient glioblastoma

A common genetic deficiency empowers glioblastoma to broadcast a molecular message to the wrong type of immune cell, summoning macrophages that protect and nurture the brain tumor instead of attacking it, researchers at The University of Texas MD Anderson Cancer Center report in Cancer Cell.

Promising methods for early detection and treatment of rheumatoid arthritis

Rheumatoid arthritis is a chronic inflammatory autoimmune disorder that leads to significant health issues as well as high treatment costs. In this themed issue of Clinical Therapeutics, published by Elsevier, experts review multiple aspects of RA detection and intervention with the overall goal of moving the field closer to developing effective preventive measures.

AI tool can aid in the diagnosis of brain aneurysms

Doctors could soon get some help from an artificial intelligence tool when diagnosing brain aneurysms - bulges in blood vessels in the brain that can leak or burst open, potentially leading to stroke, brain damage or death.
