  • Lack of REM sleep may lead to higher risk for dementia
    Spending less time in REM (rapid eye movement) sleep and taking longer to enter REM sleep are separately associated with a higher risk of developing dementia. Read more »
  • Brain activity may be predictor of stress-related cardiovascular risk
    The brain may have a distinctive activity pattern during stressful events that predicts bodily reactions, such as rises in blood pressure that increase risk for cardiovascular disease, according to new proof-of-concept research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

  • Test reveals potential treatments for disorders involving MeCP2
    Having twice the normal amount of the protein MeCP2, a condition called MECP2 duplication syndrome, causes severe progressive neuropsychiatric disorders that include intellectual disability, autism spectrum disorders, motor dysfunction and other medical complications. In animal models, normalization of MeCP2 levels has largely reversed the neurological problems, opening the possibility that a similar approach might lead to treatments for patients with these conditions. In a paper published in Science Translational Medicine, a team of researchers from Baylor College of Medicine, the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital, Stanford University School of Medicine and the University of California, San Francisco has developed a strategy that allows them to identify potential treatments that would restore altered levels of MeCP2.

  • More education linked to better cognitive functioning later in life
    Higher levels of education are tied to later ages of peak cognitive functioning, according to new research published today in the journal PLOS ONE. Read more »
  • New equipment maps brain activity and blood flow in state-of-the-art neuroscience lab
    Using lasers and photodetectors, a new optical brain-imaging tool is providing a never-before-seen look inside your head. The non-invasive tool projects and measures infrared light as it is projected into the brain and the rate at which it exits, painting a picture of brain activity and blood flow at the same time—something that is impossible without this technology.

  • Study finds link between malnutrition, alcoholism and tuberculosis in India
    A new study reveals a striking link between malnutrition, heavy alcohol use and tuberculosis (TB) in southern India. Read more »
  • Scientists discover common obesity and diabetes drug reduces rise in brain pressure
    Research led by the University of Birmingham, published today in Science Translational Medicine, has discovered that a drug commonly used to treat patients with either obesity or Type II diabetes could be used as a novel new way to lower brain pressure. Read more »
  • Few smokers hospitalized with CHD get smoking cessation meds
    (HealthDay)—Few smokers hospitalized for coronary heart disease (CHD) receive smoking cessation pharmacotherapy (SCP), according to a research letter published online Aug. 21 in JAMA Internal Medicine. Read more »
  • Research could treat Type I Diabetes by engineering pancreatic islets outside the body
    Tiny packets of cells called islets throughout the pancreas allow the organ to produce insulin. Type 1 diabetes—also known as juvenile diabetes - tricks the immune system into destroying these islets. Patients must take insulin daily to maintain blood sugar, or too much sugar will build up in the blood stream and lead to hyperglycemia, diabetic ketoacidosis, and, if left untreated, death. Patients must self-regulate their blood sugar for their entire lives, unless there were some way to restore the pancreatic islets. Read more »
  • Researchers develop faster, more accurate test for liver cancer
    It's estimated that about 788,000 people worldwide died of liver cancer in 2015, the second-leading cause of cancer deaths, according to the latest statistics from the World Health Organization. One of the major challenges in combatting this disease is detecting it early because symptoms often don't appear until later stages. Read more »
  • Selecting most effective materials for dental pulp tissue engineering
    To regenerate dental pulp tissue after emptying of a tooth's root canals researchers compared the effectiveness of 3D scaffolds made of natural or customized synthetic materials containing pulpal stem cells and dentin-derived growth factors. The substantial differences in terms of scaffold degradation, cell viability, vascularization, and pulpal tissue formation are reported in Tissue Engineering, Part A. Read more »

  • On the other hand, the immune system can also cause cancer
    Infection with human papillomavirus (HPV) is the primary cause of cervical cancer and a subset of head and neck cancers worldwide. A University of Colorado Cancer Center paper describes a fascinating mechanism that links these two conditions—viral infection and cancer. The link, basically, is a family of enzymes called APOBEC3. These APOBEC3 enzymes are an essential piece of the immune system's response to viral infection, attacking viral DNA to cause disabling mutations. Unfortunately, as the paper shows, especially the action of family member APOBEC3A can spill over from its attack against viruses to induce DNA mutations and damage in the host genome as well. In other words, this facet of the immune system designed to scramble viral DNA can scramble human DNA as well, sometimes in ways that cause cancer. Read more »
  • NT-ProBNP-guided treatment no benefit in high-risk HFrEF
    (HealthDay)—For high-risk patients with heart failure and reduced ejection fraction (HFrEF), an amino-terminal pro-B-type natriuretic peptide (NT-proBNP)-guided treatment strategy does not improve clinical outcomes versus usual care, according to a study published in the Aug. 22/29 issue of the Journal of the American Medical Association.

  • In T2D, glycemic control up with continuous glucose monitoring
    (HealthDay)—Adults with type 2 diabetes receiving multiple daily insulin injections randomized to continuous glucose monitoring (CGM) have improved glycemic control versus usual care, according to a study published online Aug. 22 in the Annals of Internal Medicine. Read more »
  • A pair of medical magnets shows promise as a new tool for creating an anastomosis
    An experimental device that employs a pair of magnets offers surgeons a new safe and simple alternative to standard methods for creating an anastomosis for the first time in nearly 50 years. An anastomosis is a surgical connection between tubular anatomic structures, such as blood vessels, urinary tract, or bowel. In its first proof-of-concept clinical trial in humans, the device was easy for surgeons to use, even with patients who required complicated surgical reconstruction. It also was safe; none of the patients had any complications related to the use of the device or the anastomosis it fashioned. Findings from the clinical trial now appear as an "article in press" on the Journal of the American College of Surgeons website in advance of print. Read more »
