In a new study, researchers have developed updated guidelines for classifying a serious form of skin cancer called invasive melanoma. The American Joint Committee on Cancer, an organization that provides information on “cancer staging,” or the severity of individual cases of cancer, recently updated its guidelines for melanoma. The researchers found that when pathologists used

People going through hard times often find assistance by talking about their problems with others, and the support people receive has documented health benefits. However, the quality of support can vary and what happens during conversations can determine whether or not the support is actually beneficial. In a new three-year project funded by the National

Most people are familiar with A, B, AB and O blood types, but there are hundreds of additional blood group “antigens” on red blood cells—substances that can trigger the body’s immune response—that differ from person to person. Each year, up to 16 deaths reported to the Federal Drug Administration are attributed to mismatches in red

Detail revealed in MRI brain scans can help doctors accurately deduce when a stroke begins, according to new research, allowing treatment for many patients who currently cannot receive it. The findings could help to better treat stroke patients, particularly those who wake up with stroke symptoms. Currently, those patients who do not know when their

Although the genitourinary syndrome of menopause (GSM) is more prevalent in survivors of breast cancer than in other menopausal women, it is commonly undiagnosed and untreated. This led The North American Menopause Society (NAMS) and The International Society for the Study of Women’s Sexual Health (ISSWSH) to form a multidisciplinary Consensus Panel to develop recommendations

The study entitled “Long term extension of a randomised controlled trial of probiotics using electronic health records” led by researchers in the Swansea University Medical School and the College of Human and Health Sciences, was published in Scientific Reports. The findings demonstrate the potential of using anonymised routinely collected electronic health records, such as those

A new report generated by a team at Johns Hopkins Bloomberg School of Public Health suggests we might be fearing the wrong types of viruses. Instead of worrying about Ebola or Zika, the report contends, we should be worrying about airborne infections because they pose a greater risk of pandemic. The media tends to focus

The head of the World Health Organization said Sunday there has been another reported case of Ebola in the Democratic Republic of Congo and that an experimental vaccine to fight the disease is expected to become available in the country this week. Doctor Tedros Adhanom Ghebreyesus, on a two-visit to DR Congo, said the suspected

A stem cell is one with infinite possibilities. So, for decades, scientists have puzzled over how the cell chooses to keep being a stem cell and continue dividing, or specialize into a specific cell type, like a heart or brain cell. The same type of decision is made by HIV. When the virus infects a

The majority of patients eligible for cancer immunotherapy drugs known as checkpoint inhibitors received treatment within a few months of FDA approval, according to a new Yale-led study. The finding suggests that cancer immunotherapies are adopted at a much quicker pace than is typical for newly approved medical treatments, the researchers said. However, patients receiving

Lung cancer is the second most prevalent form of cancer in men and women and the top cancer killer among both sexes. The American Cancer Society (ACS) estimate that in 2018, 154,050 people in the United States will have died from the disease. The World Health Organization (WHO) suggest that 1.69 million deaths are brought

The level of diversity of the ‘good bacteria’ in our digestive systems has been found to be linked to a feature of cardiovascular disease – hardening of the arteries – in new research by experts at the University of Nottingham and King’s College London. The gut microbiome is under increasing scrutiny in medical research as

A brain protein called tau is known to play a key role in the development of Alzheimer’s disease. Our brain cells have a “transport system” made of straight, parallel “roads,” along which food molecules, nutrients, and discarded parts of cells can travel. In a healthy brain, the protein tau helps these tracks to stay straight.

Recent advances in scientific understanding of how posttraumatic stress disorder (PTSD) develops and persists may lead to more effective treatment and even prevention of this debilitating disorder, according to the May/June special issue of Harvard Review of Psychiatry. A growing body of evidence helps psychiatrists to understand the aspects of brain structure and function involved

Two patients with mycosis fungoides (MF) can appear to have identical diseases upon first diagnosis but can have radically different outcomes. MF in an unusual cancer of the T lymphocyte that begins in the skin rather than in the lymph nodes, with the first sign often being a rash. Most patients with MF, the most

Prophylactic mass vaccination programmes are not a realistic option in the battle to prevent new Ebolavirus outbreaks, a University of Kent-led research team has shown. The findings come as the World Health Organisation has announced a new Ebola virus outbreak in the Democratic Republic of Kongo. The team analysed the prospects for various Ebolavirus vaccines

Anxiety has already been shown to take its toll on the human body in many ways, including increased risk for heart disease and gastrointestinal disorders. Now a new study demonstrates how anxiety levels are linked to an increased risk of bone fractures in postmenopausal women. Study results are published online today in Menopause, the journal

We rely on our ears to tell us where sounds—from the chirp of a bird to the call of your name in a crowd—are coming from. Locating and discriminating sound sources is extremely complex because the brain has to process spatial information from many, sometimes conflicting, cues. Using virtual reality and other immersive technologies, researchers

Spinal muscular atrophy (SMA) is a genetic disease that can leave infants with weak muscles and trouble breathing. Many with the disease die before age two. To help these patients, doctors need therapies that target the genetic mutation and stop its progression. Now, scientists at the California Institute for Biomedical Research (Calibr) and The Scripps

How new blood vessels form in mammals, for example, during development or after injury, is imperfectly understood. Scientists at Goethe University have now shed light on this process, showing that single cells in the innermost layer of blood vessels proliferate after injury, and in so doing, make a significant contribution to the formation of new
