Monocyte-derived cells of the brain (MDCB) are a diverse group of functional immune cells that are also highly abundant in gliomas. There is growing evidence that MDCB play essential roles in the pathogenesis of gliomas. The aim of this review was to collate and systematize contemporary knowledge about these cells as they relate to glioma progression and antiglioblastoma therapeutic modalities with a view toward improved effectiveness of therapy. ⋯ Elucidating the role of mononuclear-derived cells associated with gliomas is crucial in designing novel immunotherapy strategies. Much progress is needed to characterize markers to identify cell subsets and their specific regulatory roles. Investigation of MDCB can be clinically relevant. Specific MDCB populations potentially can be used for glioma therapy as a target or as cell vehicles that might deliver cytotoxic substances or processes to the glioma microenvironment.

As the aged population is rapidly growing globally, geriatric traumatic brain injury (TBI) becomes an increasing problem. There are higher mortality and poorer functional outcome in the geriatric TBI population (≥65 years) compared with younger groups despite neurosurgical interventions. Therefore, current treatment priorities and cost-effectiveness should be critically examined. We evaluated the benefit of surgical management in the elderly (≥65 years) after TBI. ⋯ We confirmed that age is a major determinant of outcome after TBI. In addition, we found that neurosurgical management is associated with the improvement of the prognosis and a decrease in the rate of mortality in geriatric TBI. However, surgical management was not shown to be an effective treatment in elderly patients with GCS scores of 3-5.

To update outcomes and assess prognostic factors in the modern, multimodality treatment of patients with pineoblastoma. ⋯ Modern, multimodality treatment of pineoblastoma yields a high rate of overall survival, with acceptable short- and long-term toxicity. A greater M-stage at presentation and development of disease recurrence correlate with worse overall survival. Patients who received focal radiation initially experienced a greater rate of disease recurrence compared with those treated to the craniospinal axis.

Metastases to the spine are a common manifestation of breast cancer leading to considerable reduction in the patient's quality of life. Physicians must consider the different treatments available to decrease pain, reduce tumor burden, and ensure spinal stability to prevent neurological compromises. The first objective of this study is to analyze the epidemiology and outcomes of patients with spinal metastases from breast cancer and describe changes over time in these lesions. The second objective is to establish the current treatment of spinal metastases in this type of cancer. ⋯ The survival rate was better in patients with spinal metastases who received specific treatment. The evolution from lytic spinal metastasis to mixed and blastic subtypes is observed with adjunctive therapy for spinal metastases (bisphosphonates, radiotherapy). Increased attention must be given for high-grade breast cancer, as spinal metastases declare faster for these stages. This study provides evidence that a multidisciplinary tumor board specifically focusing on bone metastasis is essential to effectively manage patients with breast cancer and spinal metastasis.

Subthalamic nucleus (STN) deep brain stimulation (DBS) is an established treatment for patients with advanced Parkinson disease. However, some patients feel less satisfied with the outcome of surgery. We sought to study the relationship between expectations, satisfaction, and outcome in STN DBS for Parkinson disease. ⋯ Addressing patients' expectations both preoperatively and postoperatively may play an important role in patient satisfaction, and therefore overall success, of STN DBS surgery for Parkinson disease.
