NLR May Be Tied to Survival in Patients With NSCLC Brain Metastases

NEW YORK (Reuters Health) – In patients with non-small cell lung cancer brain metastases (NSCLCBM) treated with immune-checkpoint inhibitors (ICIs) and upfront steroids, a low neutrophil-to-lymphocyte ratio (NLR) was associated with lower overall survival in a single-center retrospective analysis. “With widespread implementation of ICIs for treatment of NSCLC, many clinicians have concerns that the immunosuppressive […]

Microrna-29 molecule controls brain maturation in mammals

A team led by scientists at the UNC School of Medicine identified a molecule called microRNA-29 as a powerful controller of brain maturation in mammals. Deleting microRNA-29 in mice caused problems very similar to those seen in autism, epilepsy, and other neurodevelopmental conditions. The results, published in Cell Reports, illuminate an important process in the […]

Study investigates the effects of depression on visual perception

Researchers specialized in psychiatry and psychology at the University of Helsinki investigated the effects of depression on visual perception. The study confirmed that the processing of visual information is altered in depressed people, a phenomenon most likely linked with the processing of information in the cerebral cortex. The study was published in the Journal of […]

Type 2 Diabetes Linked to Increased Risk for Parkinson’s

New analyses of both observational and genetic data have provided “convincing evidence” that type 2 diabetes is associated with an increased risk for Parkinson’s disease. Dr Alastair Noyce “The fact that we see the same effects in both types of analysis separately makes it more likely that these results are real — that type 2 […]
