Editorial to Advances in Minimally Invasive Spine Surgery.

Degenerative spinal pathology is a leading cause of morbidity in the United States with a predicted increase in prevalence as the population ages [...

Safety and efficacy of minimally invasive posterior cervical fusion: a single center, single surgeon retrospective review.

Standard posterior cervical fusion is a common surgical technique that utilizes lateral mass screws and rods for fixation. A relatively new, minimally invasive technique involving interfacet decortication and placement of spacers has shown promise in terms of outcomes. We sought to determine fusion rates and complications of this new technique at our institution to bolster current literature.

Safety and timing of early therapeutic anticoagulation therapy after craniotomy.

Background: To date, there are few guidelines and studies to guide the timing of initiation of therapeutic anticoagulation (AC) after craniotomy. The goal of this study was to assess the timing, safety, and outcomes of patients following the administration of therapeutic AC after craniotomy.

Methods: A retrospective case-control study was performed evaluating all craniotomy patients from August 2017 to July 2021.

Arachnoid webs with spinal cord compression: insights from three cases.

Spinal arachnoid webs are intradural bands of abnormally formed arachnoid tissue, located within the subarachnoid space and causing compression of the dorsal aspect of the spinal cord. Arachnoid webs are uncommon and can be difficult to treat. We report 3 patients presenting with a spinal arachnoid web within a 6-month period.

Persistent brainstem abscess requiring repeat microsurgical drainage: case report.

In this paper, we present a patient who was treated for a pontine abscess at our institution. This patient underwent sub-occipital craniotomy for microscopic abscess drainage after which cultures grew . She was treated with antibiotics but failed to show clinical improvement and was taken back to the operating room for repeat abscess drainage.

Low-Dose Intravenous Heparin Infusion After Aneurysmal Subarachnoid Hemorrhage is Associated With Decreased Risk of Delayed Neurological Deficit and Cerebral Infarction.

Background: Patients who survive aneurysmal subarachnoid hemorrhage (aSAH) are at risk for delayed neurological deficits (DND) and cerebral infarction. In this exploratory cohort comparison analysis, we compared in-hospital outcomes of aSAH patients administered a low-dose intravenous heparin (LDIVH) infusion (12 U/kg/h) vs those administered standard subcutaneous heparin (SQH) prophylaxis for deep vein thrombosis (DVT; 5000 U, 3 × daily).

Objective: To assess the safety and efficacy of LDIVH in aSAH patients.

Mechanisms regulating PD-L1 expression on tumor and immune cells.

Background: The PD-1/PD-L1 checkpoint is a central mediator of immunosuppression in the tumor immune microenvironment (TME) and is primarily associated with IFN-g signaling. To characterize other factors regulating PD-L1 expression on tumor and/or immune cells, we investigated TME-resident cytokines and the role of transcription factors in constitutive and cytokine-induced PD-L1 expression.

Methods: Thirty-four cultured human tumor lines [18 melanomas (MEL), 12 renal cell carcinomas (RCC), 3 squamous cell carcinomas of the head and neck (SCCHN), and 1 non-small-cell lung carcinoma (NSCLC)] and peripheral blood monocytes (Monos) were treated with cytokines that we detected in the PD-L1+ TME by gene expression profiling, including IFN-g, IL-1a, IL-10, IL-27 and IL-32g.

Investigating the Gender Pay Gap in Industry Contributions to Academic Neurosurgeons.

Background: A large gender gap exists in industry funding for academic neurosurgeons. Selection criteria for funding distribution remain unclear. However, academic rank, scholarly productivity, and experience have been suggested as determining factors.
