Parkinson's disease (PD) is a neurodegenerative disorder characterized by both motor and nonmotor symptoms. Although the basal ganglia traditionally primary brain region implicated in this process, limited view ignores roles of cortex cerebellum that are networked with to support cognitive functions. In particular, recent research has highlighted dysfunction supplementary complex (SMC) patients PD. Using PubMed Google Scholar search engines, we identified articles using keywords pertaining...

OBJECTIVE The use of osteobiologics, engineered materials designed to promote bone healing by enhancing growth, is becoming increasingly common for spinal fusion procedures, but the efficacy some these products unclear. authors performed a retrospective, multi-institutional study investigate clinical and radiographic characteristics patients undergoing single-level anterior cervical discectomy with using osteobiologic agent Osteocel, an allograft mesenchymal stem cell matrix. METHODS medical...

The breast is one of the common primary sites brain metastases (BM). Radiotherapy for BM from cancer may include whole radiation therapy (WBRT), stereotactic radiosurgery (SRS), and radiotherapy (SRT), but a consensus difficult to reach because wide varied protocols, indications, outcomes these interventions. Overall, dissemination disease, patient functional status, tumor size are all important factors in decision treatment with WBRT or SRS. Thus far, previous studies indicate that can...

Hypothesis: Intraoperative electrocochleography (ECochG) can differentiate hair cell and neural dysfunction caused by a vestibular schwannoma (VS) help define the site of lesion as peripheral or central to spiral ganglion. Background: Hearing loss in patients with VS be both sensory (cochlear) dysfunction. Methods: Round-window ECochG using low high-frequency tone bursts was performed 49 subjects VS. Responses were analyzed for magnitude, spectrum, shape time waveform. Components examined...

Study Design: Retrospective cohort study. Objective: We aimed to characterize the treatment patterns and associated costs in patients with cerebrospinal fluid (CSF) leak after spine procedures United States. Background: CSF is a common complication spinal procedures. However, there little data regarding national of choice health care resource utilization. Methods: utilized IBM MarketScan Research databases retrospectively analyze adult US diagnosed within 30 days between 2001 2018. Treatment...

Achromobacter xylos strain GSR21 plays a crucial role in bioremediation of fossil fuel contamination, biopharmaceutical, cosmetics, chemical, petroleum refining, petrochemical, food industries and tertiary oil recovery (Microbial enhanced recovery). Response surface quadratic models (RSQM) was applied to reinforce the censorious operating conditions for assembly GSR21. The method (RSM) application determine best degrees cycle factors (Temperature, Concentration, RPM, pH). Central composite...

Background: Painful diabetic peripheral neuropathy (pDPN) is a debilitating complication of long-term diabetes. High-frequency spinal cord stimulation (HF-SCS) was recently shown to be an effective treatment option, but the associated healthcare resource utilization (HCRU) on real-world patient populations with pDPN unknown. Methods: Using IBM MarketScan databases, we identified patients HF-SCS implantation between January 2016 and December 2019 who had diagnosis diabetes or within two years...

INTRODUCTION: Usage of osteobiologics is becoming increasingly common for spinal fusion procedures, but the efficacy certain products unclear. METHODS: The medical record across three centers and seven spine surgeons was retrospectively queried patients undergoing single-level ACDF utilizing Osteocel. Pseudarthrosis determined based on computed tomography (CT) or x-rays cervical spine. Patients were to have radiographic pseudarthrosis if they met any following criteria: 1) lack bridging bone...
