Multicenter Study Observational Study
Safety and efficacy of the Neuroform Atlas for stent-assisted coiling of intracranial aneurysms: A multicenter experience.
Clinical data on the new Neuroform Atlas stent for treatment of intracranial aneurysms is limited. We report our experience in stent-assisted coiling procedures of complex, predominantly wide-necked aneurysms. ⋯ Our results demonstrate that treatment of intracranial aneurysms with the Neuroform Atlas stent is associated with low morbidity and a high aneurysm occlusion rate at mid-term follow-up. Further studies will be necessary to confirm our results.

Multicenter Study Observational Study
COMT Val158Met polymorphism is associated with post-traumatic stress disorder and functional outcome following mild traumatic brain injury.
Mild traumatic brain injury (mTBI) results in variable clinical trajectories and outcomes. The source of variability remains unclear, but may involve genetic variations, such as single nucleotide polymorphisms (SNPs). A SNP in catechol-o-methyltransferase (COMT) is suggested to influence development of post-traumatic stress disorder (PTSD), but its role in TBI remains unclear. ⋯ PTSD emerged as a strong predictor of poorer outcome on GOSE (multivariable OR 0.09, 95% CI [0.03-0.26]), which persists after controlling for age, GCS, and race. When accounting for PTSD in multivariable analysis, the association of COMT genotype and GOSE did not remain significant (multivariable OR 1.73, 95% CI [0.69-4.35]). Whether COMT genotype indirectly influences global functional outcome through PTSD remains to be determined and larger studies in more diverse populations are needed to confirm these findings.

Thirty-day readmission rate and risk factors for patients undergoing single level elective anterior lumbar interbody fusion (ALIF).
Anterior lumbar interbody fusion (ALIF) represents a common interbody fusion technique and is advantageous given reduced risk of damage to the paraspinal muscles, posterior ligaments, and neural elements. In this study, we identified the readmission rate, common causes, and risk factors associated with single level ALIF 30-day readmission. Patients who underwent elective single level ALIF surgery from 2011 to 2013 were identified in the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database. ⋯ Bleeding disorders, anemia, and perioperative blood loss was not associated with 30-day readmission. Limitations include retrospective level 3 data, and missing data. This study represents the first nation-wide descriptive evaluation of 30-day readmission causes and risk factors for patients undergoing an ALIF procedure.

Multicenter Study Clinical Trial
Reducing post-lumbar puncture headaches with small bore atraumatic needles.
Lumbar puncture for testing of Alzheimer's disease pathophysiology for diagnostic confirmation is likely to become more common in the coming years. Minimizing adverse effects from this testing will be essential for clinical practice. ⋯ We assessed PLPH in the Alzheimer's Disease Neuroimaging Initiative cohort and found that PLPH occurrence was reduced only when using a 24 gauge atraumatic needle. We recommend that lumbar punctures for clinical and research purposes in Alzheimer's disease be conducted with 24 gauge atraumatic needles.

Uses and limitations of indocyanine green videoangiography for flow analysis in arteriovenous malformation surgery.
Intra-operative indocyanine green (ICG) videoangiography is a useful addition to cerebrovascular neurosurgery. ICG videoangiography is useful in different phases of arteriovenous malformation (AVM) surgery. Additionally, it can be used to perform semi-quantitative flow analysis. ⋯ Only one patient of 23 (4.3%) showed residual AVM on post-operative digital subtraction angiography or CT angiography despite negative intra-operative ICG. ICG videoangiography is a useful addition to AVM surgery, but it has some limitations. Flow analysis is a new capability that allows for semi-quantitative AVM perfusion analysis.
