Posterior fossa meningiomas: perioperative predictors of extent of resection, overall survival and progression-free survival
AbstractBackgroundPosterior fossa meningiomas (PFMs) often represent surgical challenges due to their proximity to neurovascular structures. Factors predicting the extent of resection (EOR), overall survival (OS), and progression-free survival (PFS) were identified and integrated in a prediction tool to offer evidence-based personalized therapeutic strategies.MethodsAll meningiomas managed surgically from 1990 to 2010 from a single-center were reviewed. A classification tree was created using the classification and regression tree recursive partitioning analysis that incorporated patient and tumor data available before surgery in order to predict the rates of gross total resection (GTR).ResultsA total of 198 patients were identified (female-to-male ratio, 2.7; mean age, 59.1 years) and compared with 1271 supratentorial meningiomas (STMs) operated in the same institution during the same time period. GTR was achieved less often (59.6% versus 81.9%;p
In conclusion, BLU-5937 was selected as a drug candidate for the treatment of chronic cough due to its high potency and selectivity for P2X3 homotrimeric receptors, strong anti-tussive effects, excellent tolerability and predicted pharmacokinetic properties in humans.
ConclusionThe SOS presents nearly as good as the SOFA score, to predict mortality among sepsis patients admitted to the ICU. The early warning score is another, alternative tool to use for risk stratification and sepsis screening for ICU sepsis patients.
Conclusions: Echogenicity of a pleural effusion has a low specificity for identifying an underlying exudate, and the echogenic qualities of the fluid should not influence clinical decision-making.Respiration
MRC Laboratory of Molecular Biology researchers reveal atomic structures of the abnormal tau filaments associated with chronic traumatic encephalopathy, a head injury-associated neurodegenerative disease, differ in structure from those seen in Alzheimer’s disease.
ConclusionsThese findings indicate that the neural effects of AUD vary according to severity. Our results emphasize the utility of resting state fMRI as a neuroimaging biomarker for quantitative clinical evaluation of AUD.

Schild, Thomas Klockgether, Henning BoeckerAbstractMany studies have used functional magnetic resonance imaging to unravel the neuronal underpinnings of motor system abnormalities in Parkinson's disease, indicating functional inhibition at the level of basal ganglia-thalamo-cortical motor networks. The study aim was to extend the characterization of functional motor changes in Parkinson's Disease by dissociating between two phases of action (i.e. m...
ConclusionsA clinically relevant model of PTA of venous stenosis in mice was created. PTA-treated vessels had increased lumen vessel area and WSS. The alterations in tissue markers of vascular remodeling, tissue hypoxia, proliferation, and cell death may be implications for future design of drug and device development.
ConclusionWEB shape modification was observed in more than half of cases but with no influence regarding adequate occlusion rate. This quantitative approach of WSM highlights that this phenomenon appears to be early and progressive over time. This supports the hypothesis that WSM could be more probably related to aneurysm healing rather than external compression.
