"Sugar sponges" - diabetes treatment of the future?
Many diabetes patients must inject themselves with insulin, sometimes several times a day, while others take medications orally to control blood sugar. The injections, as well as the side effects from both regimens, can be painful. Now, one team reports in the Journal of the American Chemical Society progress toward an insulin-free diabetes treatment that requires fewer injections.

Tumor induction from a distance
Current view is that cancer development is initiated from cells that acquire initial DNA mutations. These in turn provoke additional defects, and ultimately the affected cells begin to proliferate in an uncontrolled manner to develop primary tumors. These can later spread and create metastases, or secondary tumors, in other parts of the body. However, according to a study by researchers at the…
How does the body process pain? Study sheds new light
Currently available pain medications have limited efficacy and numerous side effects. New research, however, provides deeper insights into how our bodies process pain, paving the way for an innovative, more effective way of targeting chronic pain.

Handheld scanner reveals vascularization in psoriasis patients
A newly developed tissue scanner allows looking under the skin of psoriasis patients. This provides clinically relevant information, such as the structure of skin layers and blood vessels, without the need for contrast agents or radiation exposure. A team of researchers from Helmholtz Zentrum München and the Technical University of Munich (TUM) recently introduced the technology in ‘Nature…

Study provides better understanding of how brain tumors ‘feed’
All cancer tumors have one thing in common – they must feed themselves to grow and spread, a difficult feat since they are usually in a tumor microenvironment with limited nutrients and oxygen. A study at The University of Texas MD Anderson Cancer Center has revealed new details about how an enzyme called acetyl-CoA synthetase 2 (ACSS2) allows brain tumors to grow despite their harsh…

App accelerates deployment of first responders
Point of Care Diagnostics (POCT) has been established for 20 years. Comprehensive smartphone coverage and shareconomy technology are now helping to push the development from previous business models towards a point of patient model. The question is whether medical apps will have the same benefit as those employed for everyday use. Report: Anja Behringer

Scientists identify protein linked to chronic heart failure
Researchers in Japan have identified a receptor protein on the surface of heart cells that promotes chronic heart failure. The study, “Corticotropin releasing hormone receptor 2 exacerbates chronic cardiac dysfunction” suggests that inhibiting this protein could help treat a disease that affects more than 20 million people worldwide.

Our brains detect disease in others even before it breaks out
The human brain is much better than previously thought at discovering and avoiding disease, a new study led by researchers at Karolinska Institutet in Sweden reports. Our sense of vision and smell alone are enough to make us aware that someone has a disease even before it breaks out. And not only aware - we also act upon the information and avoid sick people.

Using machine learning to predict sepsis
A machine-learning algorithm has the capability to identify hospitalized patients at risk for severe sepsis and septic shock using data from electronic health records (EHRs), according to a study presented at the 2017 American Thoracic Society International Conference. Sepsis is an extreme systemic response to infection, which can be life-threatening in its advanced stages of severe sepsis and…

New insights into early cognitive markers of Alzheimer's
New research led by the University of Hertfordshire, may significantly change the understanding of cognitive processes that are most impaired at very early stages of Alzheimer's disease. The findings could potentially be used to detect the condition at an earlier stage and improve diagnostic accuracy, by creating new cognitive tests that are more sensitive to brain pathology than ones currently…

New-found brain pathway has implications for schizophrenia treatment
Neuroscientists at Tufts University School of Medicine have discovered a new signaling pathway that directly connects two major receptors in the brain associated with learning and memory – the N-methyl-D-aspartate receptor (NMDAR) and the alpha 7 nicotinic acetylcholine receptor (a7nAChR) – which has significance for current efforts to develop drugs to treat schizophrenia.

Potential predictor of glaucoma damage identified
Glaucoma, a leading cause of blindness worldwide, most often is diagnosed during a routine eye exam. Over time, elevated pressure inside the eye damages the optic nerve, leading to vision loss. Unfortunately, there’s no way to accurately predict which patients might lose vision most rapidly. Now, studying mice, rats and fluid removed from the eyes of patients with glaucoma, researchers at…
