Aging influences the diagnosis and treatment of heart attacks in patients over age 75

For people ages 75 and older, age-related changes in general health and in the heart and blood vessels require consideration and likely modifications in how heart attacks and heart disease are treated, according to a new American Heart Association scientific statement published today in the Association's flagship, peer-reviewed journal Circulation.

Study proposes a new concept for treating COVID-19 associated weight loss

Losing too much weight when infected with COVID-19 has been linked to worse outcomes. Now, researchers at Karolinska Institutet in Sweden have discovered that SARS-CoV-2 infection fuels blood vessel formation in fat tissues, thus revving up the body's thermogenic metabolism.

For patients with sickle cell disease, fertility care is about reproductive justice

Teonna Woolford has always wanted six kids. Why six? "I don't know where that number came from. I just felt like four wasn't enough," said Woolford, a Baltimore resident. "Six is a good number."

Study shows how dietary saturated/trans fats promote liver tumorigenesis

Fatty foods harm our health. Prior research has established a link between the consumption of dietary fats and non-alcoholic fatty liver disease, which subsequently leads to inflammation and tumor formation in the liver.

Low-intensity ultrasound therapies may help rebuild stronger knees

Low-intensity ultrasound therapies may one day rebuild stronger knees following injury or surgery, thanks to research by Dr. Anu Subramanian at The University of Alabama in Huntsville (UAH) that's being supported by the National Institutes of Health.

Enrollment in Medicare Advantage not associated with higher rate of heart attack survival

Nearly half of Americans with Medicare now get their health insurance coverage through a private company that takes part in the federal government's Medicare Advantage program.

New approach enables robust intestinal mini-organs to be grown more easily in the lab

Growing human body parts in the lab is a common trope of horror movies and sci-fi books. But growing miniature organ-like tissues in the lab is already within our reach.

New technology could increase scan speeds of three-dimensional MRIs

Nicholas Dwork, PhD, assistant professor in the Department of Biomedical Informatics at the University of Colorado School of Medicine, has filed a provisional patent for a technology that could increase scan speeds of three-dimensional magnetic resonance imaging (MRI).

Research explores how alignment of endothelial cells plays a role in cancer metastasis

Preventing metastasis – the development of cancer cells beyond their original location – remains one of the major goals of current cancer research.

Natural material derived from seaweed can help improve outcomes after heart bypass surgery

Researchers are using a natural material derived from seaweed to promote vascular cell growth, prevent blood clots and improve the performance of synthetic vascular grafts used in heart bypass surgery.

Researchers develop 3D organoid model to advance understanding of gastroesophageal junction cancer

Researchers at Johns Hopkins Medicine say they have created a laboratory-grown three-dimensional "organoid" model that is derived from human tissue and designed to advance understanding about how early stages of cancer develop at the gastroesophageal junction (GEJ) — the point where the digestive system's food tube meets the stomach.

HU begins human trial for promising treatment to reverse paralysis and language disorder after stroke

Hiroshima University started the human trial for a promising treatment that offers hope in potentially reversing paralysis and language disorder after moderate to severe stroke using therapeutically superior mesenchymal stem cells (MSCs) derived from the cranial bone.

Study compares the performance of two most popular AMD drugs

A pilot, "look-back" study of information about 106 patients with "wet" age-related macular degeneration (AMD) treated at the Wilmer Eye Institute at Johns Hopkins Medicine has revealed that nearly half of patients treated with aflibercept could safely stop eye injection therapy after one year without further vision loss.

Stem cell crosstalk with the microenvironment creates a loop of tumor-promoting factors

What drives tumor growth? Is it a few rogue cells imposing their will upon healthy tissue, or diseased tissue bringing out the worst in otherwise peaceable cells? Or is it a back-and-forth, a dialogue between the two?

Powerful imaging tool creates 3D atlas of the spectrum of tuberculous and COVID-19 lung lesions

Gross anatomy reveals three-dimensional shapes of pathology at a large scale. Histology, in contrast, reveals the microscopic anatomy of biological structures. But that magnification comes at a cost -; histology shows only two-dimensional shapes because it studies small, flat slices of stained tissue.

Endogenous system may be responsible for delayed onset of diabetic retinopathy

About one third of patients with diabetes mellitus (DM) develop diabetic retinopathy (DR), a leading cause of blindness in working-age individuals. DR typically develops after many years of DM, and some patients do not develop DR for more than 50 years.
