In diffuse WHO grade II gliomas (LGG), the extent of resection (EOR) required to achieve significant survival benefits remains elusive. ⋯ Our data support the hypothesis of a continuous relationship of RV and EOR with survival for LGG with superiority seen for GTR. Hence, GTR should be achieved whenever safely feasible, and resections should be maximized whenever tumor has to be left behind to spare function.

Multicenter Study Observational Study
Obese Patients Benefit, but do not Fare as Well as Nonobese Patients, Following Lumbar Spondylolisthesis Surgery: An Analysis of the Quality Outcomes Database.
Given recent differing findings following 2 randomized clinical trials on degenerative lumbar spondylolisthesis (DLS) surgery, there is a need to better define how subsets of patients fare following surgery. ⋯ Obesity is associated with inferior leg pain and quality of life-but similar back pain, disability, and satisfaction-12 mo postoperatively. However, obese patients achieve significant improvements in all PRO metrics at 12 mo.

Comparative Study
A Retrospective Comparative Analysis of Titanium Mesh and Custom Implants for Cranioplasty.
Autologous bone removed during craniectomy is often the material of choice in cranioplasty procedures. However, when the patient's own bone is not appropriate (infection and resorption), an alloplastic graft must be utilized. Common options include titanium mesh and polyetheretherketone (PEEK)-based custom flaps. Often, neurosurgeons must decide whether to use a titanium or custom implant, with limited direction from the literature. ⋯ Infection rates are higher among patients receiving custom implants compared to those receiving titanium meshes. The latter should be informed of potential postsurgical discomfort, which can be managed nonsurgically and is not associated with return to the operating room.

A better understanding of differences in outcomes of mechanical thrombectomy performed within and outside clinical trials will assist in optimal implementation of the procedure for acute ischemic stroke patients in general practice. ⋯ Mechanical thrombectomy performed as part of clinical trials was associated with lower rates of in-hospital mortality and lower rates of moderate to severe disability compared with those performed outside clinical trials.

Dual antiplatelet therapy is typically employed as a means to mitigate thromboembolic complications after deployment of flow diverters, most commonly consisting of aspirin with either clopidogrel, prasugrel, or ticagrelor. Recent studies have demonstrated at least similar efficacy for ticagrelor as compared to clopidogrel in the form of periprocedural complications and angiographic results. Though controversial, systematic reviews of platelet function assay usage have demonstrated greater rates of thrombotic complications in antiplatelet hyporesponders and greater rates of hemorrhagic complications in hyperresponders. Though in its infancy, the management of antiplatelet therapy for acutely ruptured aneurysms treated with flow diversion is not yet standardized, with approaches including intravenous glycoprotein IIb-IIIa inhibitors and subsequent antiplatelet loading vs antiplatelet loading, response assessment, and subsequent treatment.
