Review Meta Analysis
Waves of Pain Relief: A Systematic Review of Clinical Trials in Spinal Cord Stimulation Waveforms for the Treatment of Chronic Neuropathic Low-Back and Leg Pain.
In the United States, chronic low back pain affects up to 37% of adults and is a multibillion dollar health care expenditure. Spinal cord simulation (SCS) has been established as an effective treatment alternative for chronic neuropathic low back and leg pain, especially for patients with failed back surgery syndrome or chronic regional pain syndrome. The field of SCS has rapidly advanced such that analgesia can now be achieved through numerous different waveforms, each claiming to offer improved outcomes. ⋯ Of 38 eligible studies reviewed, 13 randomized controlled trials were finally included in our systematic review. We reviewed evidence from randomized controlled trials in the field of SCS that have established paresthesia-based SCS, paresthesia-free high-frequency SCS, burst SCS, and subperception SCS as viable treatment options for chronic neuropathic low back and leg pain. We critically evaluated evidence that claims to support the use of one waveform over another and reviewed the literature on patient preference for different waveforms.

Therapeutic Targeting of the Notch Pathway in Glioblastoma.
Glioblastoma (GBM) is the most common and deadly form of brain tumor. After standard treatment of resection, radiotherapy, and chemotherapy, the 5-year survival is <5%. In recent years, research has uncovered several potential targets within the Notch signaling pathway, which may lead to improved patient outcomes. ⋯ Recent literature suggests targeting the Notch pathway has great potential for future therapies for GBM.

Confirming diagnosis and effective treatment for rare epithelioid glioblastoma variant: an integrated survival analysis of the literature.
Epithelioid glioblastoma (eGBM) is a very rare histologic variant of glioblastoma that has not been studied in isolation and, therefore, its optimal management has been largely assumed, but not confirmed. The aim of this study was to analyze all reported cases describing the presentation and clinical features to better understand the clinical significance of this histologic diagnosis. ⋯ These findings indicate that the histologic diagnosis of eGBM does not deviate from the clinical course of the broader glioblastoma diagnosis, despite being a unique histologic identity. These results argue against the temptation to deviate from the traditional management paradigm of surgery, radiation, and chemotherapy for glioblastoma based on this histology alone.

Aneurysmal subarachnoid hemorrhage (aSAH) is an acute cerebrovascular disease with frequent cerebral vasospasm and delayed cerebral ischemia (DCI). The use of statins for patients with aSAH is controversial. The present study evaluated the efficacy of statins in aSAH-induced vasospasm, DCI, delayed ischemic neurological deficit (DIND), mortality, and other outcomes. ⋯ Statins significantly reduced the incidence of vasospasm, DIND, DCI, and mortality in individuals with aSAH, suggesting its efficacy in aSAH.
