Black Medicare patients with ischemic stroke die at a higher rate than white patients

A long-term look at Medicare patients shows that Black patients who have an ischemic stroke (blocked blood flow to the brain) die at a higher rate than white patients, even after accounting for preexisting health conditions, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

Triglyceride-lowering medication may lower stroke risk in people with heart disease

Taking the triglyceride-lowering medication icosapent ethyl cut the risk of stroke by an additional 36% in people at increased risk of cardiovascular disease who already have their bad cholesterol levels under control using statin medications, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

New high-performance, safe MRI contrast agent for 3D vascular mapping

Heart attack and stroke are the first and second leading causes of death in developed countries, respectively. As the disease often results in sudden death with few special prognostic symptoms, early diagnosis is very important.

Lower dose of ketamine is as effective as the standard dose to treat pain in adults

A recent Loyola Medicine study found that reducing the standard dose of IV-administered ketamine in half is as effective as the larger, standard dose in reducing pain in adults.

Simple blood test using nanoparticles could enable earlier detection of acute liver damage

University of Texas at Dallas chemist Dr. Jie Zheng has spent much of his career investigating gold nanoparticles for their potential impact in the field of nanomedicine.

Inter-arm blood pressure differences in children could lead to wrong diagnosis

Blood pressure measurements in children and adolescents should be taken from both arms after new research showed substantial differences could be seen depending on which arm was used.

Organ-on-chip consortium receives huge grant to develop a universal standard for pharmaceutical industry

Scientists are pushing ahead building 'organ-on-chips', small chips with human cells, which are useful, for example, for studying cancerous metastases in the bloodstream or the development of scar tissue, or for testing the effect of drugs or food outside a human body.

Somatic gene mutations in brain cells could contribute to schizophrenia pathology

Schizophrenia is a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. Researchers have long searched for genetic influences in the disease, but genetic mutations have been identified in only a small fraction--fewer than a quarter--of sequenced patients.

Buck scientists develop a predictive model to help identify people at risk for severe COVID-19

Researchers at the Buck Institute analyzed data from the COVID-19 Symptom Tracker app used by 3 million people in the United Kingdom, adding the use of immunosuppressant medication, use of a mobility aid, shortness of breath, fever, and fatigue to the list of symptoms and comorbidities that increase the risk for severe COVID-19.

Study uncovers mechanism to help explain how maternal stress causes idiopathic preterm birth

Preterm birth is a leading cause of infant deaths and illness in the U.S. -- yet its underlying molecular causes remain largely unclear. About 40 to 50% of preterm births, defined as births before 37 weeks of pregnancy, are estimated to be "idiopathic," meaning they arise from unexplained or spontaneous labor.

First smart speaker for contactless monitoring of both regular and irregular heartbeats

Smart speakers, such as Amazon Echo and Google Home, have proven adept at monitoring certain health care issues at home. For example, researchers at the University of Washington have shown that these devices can detect cardiac arrests or monitor babies breathing.
