New study, led by Penn Medicine, reveals that this genetic cause of heart failure, which is now treatable, is significantly underdiagnosed. A genetic variant in the gene transthyretin (TTR)—which is found in about 3 percent of  individuals of African ancestry—is a more significant cause of heart failure than previously believed, […]

Chemotherapy drugs have been used to treat cancer since the 1950s. While the drugs are often lifesaving for cancer patients, they are also linked to reproductive problems, breast cancer, and other health issues in the medical staff who work with the medications. To help protect health care workers, the University […]

New findings published in the Journal of Clinical Investigation suggest that specific immune T cells from people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) show disruptions in the way they produce energy. The research was supported by the National Institutes of Health. “This research gives us additional evidence for the role […]

New research suggests that physicians evaluating young patients with hip pain should consider more than such patients’ physical health. They also should consider screening those patients for clinical depression and anxiety — impairments that researchers at Washington University School of Medicine in St. Louis have found can have a negative […]

Pancreatic cancer is one of the most aggressive and deadly cancers. Following diagnosis, patients have an average survival of less than 6 months; sadly around 10,000 patients in the UK per year die from this type of cancer. Researchers from the University of Bath have made three new molecules similar […]

Autoimmune disorders such as rheumatoid arthritis, psoriasis, and Crohn’s disease plague tens of millions of Americans and are the result of the body’s immune system, whose role is to fight against disease-causing pathogens, turning against itself. Thankfully, several new drugs designed to fight these diseases are now available. The downside—the […]

New findings could provide doctors with vital clues about how the immune system prevents cancer from recurring. The study from Winship Cancer Institute of Emory University looked at whether immune cells were present in tumor samples removed from patients with kidney and other urologic cancers. For those patients where the […]

New research from the University of Minnesota examines how secondhand smoke might impact children and adolescent cardiovascular health. Published in Pediatric Research, researchers studied the carotid artery in the neck, brachial artery in the upper arm and abdominal aorta right above the belly button in 298 people. All were between the […]

In the last decade, scientists discovered that blocking a key regulator of the immune system helped unleash the body’s natural defenses against several forms of cancer, opening up a new era of cancer immunotherapy. Now Yale scientists have essentially flipped this script and found that when impaired a molecularly similar […]

A shorter course of higher-dose radiation treatment to part of the breast is showing promise in women with early-stage breast cancer who undergo breast conserving surgery, says a study led by Hamilton researchers. Accelerated partial breast irradiation (APBI) sees larger doses of radiation delivered to parts of the breast affected […]

Researchers from Sechenov University (Project 5-100 participant) and University College Cork (Ireland) developed a new method for studying mitochondrial polarisation in live cells and tissues. This approach enables studies of mitochondria in live cells, tissues and organoids and complements existing microscopy methods. The research was published in Cytometry Part A. […]

Members of a polar research expedition have provided researchers from Charité – Universitätsmedizin Berlin and the Max Planck Institute for Human Development with an opportunity to study the effects of social isolation and extreme environmental conditions on the human brain. The researchers found changes to the dentate gyrus, an area […]

Cystic fibrosis is caused by an inherited mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Due to this mutation, the CFTR protein doesn’t embed in cell membranes to form a channel for chlorine ions the way it should. As a result, mucus-producing cells secrete a thicker-than-normal mucus that can create […]

The concept of meaning as it pertains to human lives has been one of the cornerstones of philosophy for millennia. During the past three-or-so decades, however, it has also emerged as an important data point in medical research, especially when it comes to aging populations. As it turns out, far […]

New findings from a clinical trial show that treatment with the immunotherapy drug blinatumomab is superior to standard chemotherapy for children and young adults with high- or intermediate-risk B-cell acute lymphoblastic leukemia (B-ALL) that has relapsed. Those treated with blinatumomab had longer survival, experienced fewer severe side effects, had a […]

Participants who ate a diet high in red and processed meat, fried food, refined grains and high-fat dairy were three times more likely to develop an eye condition that damages the retina and affects a person’s central vision, according to the results of a study from the University at Buffalo. […]

The antibiotic vancomycin alters the gut microbiome in a way that can help prime the immune system to more effectively attack tumor cells after radiation therapy. A new study in mice from researchers at the Abramson Cancer Center of the University of Pennsylvania found giving a dose of the common antibiotic not […]

A new study led by the Sainte-Justine University Hospital Centre and the University of Montreal, along with the Washington University School of Medicine in St. Louis, has found that transfusions using fresh red blood cell units—containing red cells that have spent seven days or less in storage—are no more beneficial […]
