BACKGROUND: Preexisting cognitive impairment in surgical patients is one of the leading risk factors for adverse cognitive outcomes such as postoperative delirium and postoperative cognitive dysfunction. We developed a self-administered tablet computer application intended to assess the individual risk for adverse postoperative cognitive outcomes. This cross-sectional study aimed to establish normative data for the tool. MATERIALS AND METHODS: Healthy volunteers aged 65 years and above were administered the Mini-Mental State Examination, Geriatric Depression Scale, and Consortium to Establish a Registry for Alzheimer's Disease-Neuropsychological Assessment Battery to assess cognitive health...

BACKGROUND: The Glasgow Coma Scale (GCS) is an essential coma scale in critical care for determining the neurological status of patients and for estimating their long-term prognosis. Similarly, cerebral autoregulation (CA) monitoring has shown to be an accurate technique for predicting clinical outcomes. However, little is known about the relationship between CA measurements and GCS scores among neurological critically ill patients. This study aimed to explore the association between noninvasive CA multimodal monitoring measurements and GCS scores...

The fragile X premutation is characterized by a repeat expansion mutation (between 55 to 200 CGG repeats) in the fragile X mental retardation 1 (FMR1) gene, which leads to RNA toxicity at the cellular level. This may cause patients with the premutation to be particularly susceptible to environmental toxins, which could manifest clinically as new or worsening ataxia and memory loss. Multiple published case reports have also suggested general anesthetics as a potential toxin leading to negative side effects when used in patients with fragile X- associated disorders...

BACKGROUND: Perioperative seizures may affect 1% to 50% of patients undergoing craniotomy and adversely impact outcomes. However, data on intraoperative seizures are limited. This retrospective case-control study investigated the incidence and risk factors for intraoperative seizures during elective supratentorial craniotomy involving evoked potential monitoring. MATERIALS AND METHODS: Patients aged 18 years or above undergoing elective supratentorial craniotomy with evoked potential monitoring who experienced intraoperative seizures at our institution between December 2008 and March 2014 were compared with a control group generated using a random number generator...

BACKGROUND: Patients with a brain tumor are susceptible to the hypnotic effect of anesthetics depending on the tumor's size. We investigated whether intracranial space-occupying lesions (ICSOLs) inducing intracranial hypertension increase isoflurane's effect on electroencephalographic (EEG) results. MATERIALS AND METHODS: After anesthetic induction with isoflurane, 11 swine were studied with regard to isoflurane's effect on EEGs at 0.5% to 2.0% inhalational concentration at sequential stages: baseline 1, ICSOL 1, baseline 2, ICSOL 2, baseline 3...

BACKGROUND: The α2 adrenergic agonist dexmedetomidine (DEX) has huge potential for protecting against cerebral vasospasm, a leading cause of death and disability after subarachnoid hemorrhage (SAH). Biomarker assays for SAH have recently emerged as tools for predicting vasospasm and outcomes. We investigated the effects of DEX on vasospasm and assessed relevant biomarkers in a rat SAH model. METHODS: Male Wistar rats were randomly assigned to sham (n=10), vehicle (n=10), SAH (n=10), or SAH+ DEX (n=10) groups...

BACKGROUND: The association between anesthesia type and outcomes in patients with acute ischemic stroke undergoing endovascular treatment (EVT) remains a subject of ongoing debate. METHODS: This prospective nonrandomized controlled trial included 149 consecutive patients with acute anterior circulation stroke who underwent EVT. The primary outcome was functional independence assessed by the modified Rankin Scale (mRS) after 3 months. RESULTS: A total of 105 (70...

BACKGROUND: The essential branched-chain amino acids (BCAAs) leucine, isoleucine, and valine have recently emerged as a potential novel treatment for medically refractory epilepsy. Blood-derived BCAAs can readily enter the brain, where they contribute to glutamate biosynthesis and may either suppress or trigger acute seizures. However, the effects of BCAAs on chronic (ie, spontaneous recurrent) seizures and epilepsy-associated neuron loss are incompletely understood. MATERIALS AND METHODS: Sixteen rats with mesial temporal lobe epilepsy were randomized into 2 groups that could drink, ad libitum, either a 4% solution of BCAAs in water (n=8) or pure water (n=8)...

BACKGROUND: External ventricular drain (EVD)-associated ventriculitis is a serious complication. Early diagnosis can be difficult particularly in critically ill patients with aneurysmal subarachnoid hemorrhage (aSAH). We examined the diagnostic potential of standard serum and cerebrospinal fluid (CSF) biomarkers to differentiate between EVD-associated infections and aseptic courses in patients with aSAH. MATERIALS AND METHODS: We retrospectively evaluated the levels of inflammatory markers in serum (white blood cell count, percentage of neutrophils [sN%], and procalcitonin) and CSF (total leukocyte count [CSFTLC], CSFglucose, CSF/serumglucose ratio, CSF total protein [CSFTP]) of 63 consecutive patients with aSAH...

BACKGROUND: Decompressive craniectomy (DC) is a life-saving intervention for malignant cerebral venous thrombosis (CVT). Earlier studies have shown increase in cerebral oxygenation after DC in traumatic brain injury but similar studies are lacking in CVT. We hypothesized that regional cerebral (tissue) oxygen saturation (rSO2) on the side of CVT is lower than the contralateral side and improves after DC. MATERIALS AND METHODS: In this prospective cohort study, rSO2 was monitored using near-infrared spectroscopy technique, before and after DC on both cerebral hemispheres...

We provide a synopsis of innovative research, recurring themes, and novel experimental findings pertinent to the care of neurosurgical patients and critically ill patients with neurological diseases. We cover the following broad topics: general neurosurgery, spine surgery, stroke, traumatic brain injury, monitoring, and anesthetic neurotoxicity.
