New biological research framework for Alzheimer’s seeks to spur discovery

10.04.2018 Health Problems

The research community now has a new framework toward developing a biologically-based definition of Alzheimer’s disease. This proposed “biological construct” is based on measurable changes in the brain and is expected to facilitate better understanding of the disease process and the sequence of events that lead to cognitive impairment and dementia. With this construct, researchers can study Alzheimer’s, from its […]

Gene test for growth hormone deficiency developed

10.04.2018 Health Problems

A new test developed by University of Manchester and NHS scientists could revolutionise the way children with growth hormone deficiency are diagnosed. Children suspected of having GHD – which cause growth to slow down or stop and other serious physical problems—currently require a test involving fasting for up to 12 hours. The fasting is followed by an intravenous infusion in […]

Study finds how fat tissue shunts energy to tumors

10.04.2018 Health Problems

Obesity is the second-leading preventable cause of cancer and represents one of the greatest threats to global human health. But it has not been clear exactly how whole-body metabolism affects tumor formation. In particular, the molecular mechanisms by which fat cells communicate with tumor tissue remain poorly understood. Sanford Prebys Medical Discovery Institute (SBP) researchers recently addressed this question, revealing […]

Sunshine could hold clues on the timing for a severe form of heart attack, study says

10.04.2018 Health Problems

The sun’s radiation could be a factor in seasonal patterns of a deadly type of heart attack, according to new research that tracked a “summer shift” in their occurrence across seven countries. Previous research has examined how these attacks – called ST-elevation myocardial infarctions, or STEMIs – seem to happen most often in the daytime during the colder winter months, […]

Antibiotic use increases risk of severe viral disease in mice

10.04.2018 Health Problems

People infected with West Nile virus can show a wide range of disease. Some develop life-threatening brain infections. Others show no signs of infection at all. One reason for the different outcomes may lie in the community of microbes that populate their intestinal tracts. A study from Washington University School of Medicine in St. Louis shows that mice are more […]

Study confirms that inflammation during pregnancy is linked to baby’s brain

10.04.2018 Health Problems

Inflammation is a normal part of the body’s response to infection, chronic stress or obesity. In pregnant women, it is believed that heightened inflammation increases the risk of mental illness or brain development problems in children. A study conducted by researchers at OHSU in Portland, Oregon, has established a link between inflammation in pregnant women and the way the newborn […]

Macular degeneration linked to aging immune cells

10.04.2018 Health Problems

As people age, their immune systems age, too. And new research at Washington University School of Medicine in St. Louis suggests that aging immune cells increase the risk for age-related macular degeneration, a major cause of blindness in the United States. Studying mice and cells from patients, the researchers found that as immune cells called macrophages age, they are more […]

Payments to doctors linked to prescription practices for two cancer types

10.04.2018 Health Problems

Physicians who received payment from pharmaceutical companies for meals, talks and travel were more likely to prescribe those companies’ drugs for two cancer types, a University of North Carolina Lineberger Comprehensive Cancer Center-led study has found. The study was published Monday in the Journal of the American Medical Association Internal Medicine. The preliminary findings were presented last year at the […]

CRISPR enhances gene therapy to fight inherited diseases

10.04.2018 Health Problems

Gene therapy has shown promise in treating inherited genetic diseases, but a major issue that has frustrated scientists remains: Replacing a “bad” gene with a healthy one often is a short-lived fix. Typically, the healthy replacement gene works for just a few weeks. Now, scientists at Washington University School of Medicine in St. Louis have combined the gene-editing tool CRISPR […]

Oral sirolimus alters the course of DIPNECH syndrome in three patients

10.04.2018 Health Problems

Sirolimus, which is used to prevent rejection after kidney transplants, has been used to successfully treat three cases of a rare disorder called diffuse idiopathic pulmonary neuroendocrine cell hyperplasia, or DIPNECH syndrome. The syndrome is so rare that there are no clinical recommendations to guide care and, therefore, no proven therapies. The brief case report is published in Annals of […]
