    Abstract Background and aims: As the prevalence of nonalcoholic fatty liver disease (NAFLD) is approximately 30% in the general population, it is important to develop a non-invasive biomarker for the diagnosis of nonalcoholic steatohepatitis (NASH). This prospective cross-sectional study aimed to develop a scoring system for NASH diagnosis through multiparametric magnetic resonance (MR) and clinical indicators.
    Methods: Medical history, laboratory tests, and MR parameters of patients with NAFLD were assessed. A scoring system was developed using a logistic regression model. In total, 127 patients (58 with nonalcoholic fatty liver [NAFL] and 69 with NASH) were enrolled. After evaluating 23 clinical characteristics of the patients (4 categorical and 19 numeric variables) for the NASH diagnostic model, an equation for MR elastography (MRE)-based NASH score was obtained using 3 demographic factors, 2 laboratory variables, and MRE.
    Results: The MRE-based NASH score showed a satisfactory accuracy for NASH diagnosis (c-statistics, 0.841; 95% CI 0.772-0.910). At a cut-off MRE-based NASH score of 0.68 for NASH diagnosis, its sensitivity was 0.68 and specificity was 0.91. When an MRE-based NASH score of 0.37 was used as a cut-off for NASH exclusion, the sensitivity was 0.91 and specificity was 0.55. Overall, 35% (44/127) of patients were in the gray zone (between 0.37 and 0.68). Internal validation via bootstrapping also indicated the satisfactory accuracy of NASH diagnosis (optimism-corrected statistics, 0.811).
    Conclusion: MRE-based NASH score is a useful and accurate non-invasive biomarker for diagnosis of NASH in patients with NAFLD.

    Abstract OBJECT Mechanical failure-which is the primary cause of CSF shunt malfunction-is not readily diagnosed, and the specific reasons for mechanical failure are not easily discerned. Prior attempts to measure CSF flow noninvasively have lacked the ability to either quantitatively or qualitatively obtain data. To address these needs, this preliminary study evaluates an ultrasonic transit time flow sensor in pediatric and adult patients with external ventricular drains (EVDs). One goal was to confirm the stated accuracy of the sensor in a clinical setting. A second goal was to observe the sensor's capability to record real-time continuous CSF flow. The final goal was to observe recordings during instances of flow blockage or lack of flow in order to determine the sensor's ability to identify these changes. METHODS A total of 5 pediatric and 11 adult patients who had received EVDs for the treatment of hydrocephalus were studied in a hospital setting. The primary EVD was connected to a secondary study EVD that contained a fluid-filled pressure transducer and an in-line transit time flow sensor. Comparisons were made between the weight of the drainage bag and the flow measured via the sensor in order to confirm its accuracy. Data from the pressure transducer and the flow sensor were recorded continuously at 100 Hz for a period of 24 hours by a data acquisition system, while the hourly CSF flow into the drip chamber was recorded manually. Changes in the patient's neurological status and their time points were noted. RESULTS The flow sensor demonstrated a proven accuracy of ± 15% or ± 2 ml/hr. The flow sensor allowed real-time continuous flow waveform data recordings. Dynamic analysis of CSF flow waveforms allowed the calculation of the pressure-volume index. Lastly, the sensor was able to diagnose a blocked catheter and distinguish between the blockage and lack of flow. CONCLUSIONS The Transonic flow sensor accurately measures CSF output within ± 15% or ± 2 ml/hr, diagnoses the blockage or lack of flow, and records real-time continuous flow data in patients with EVDs. Calculations of a wide variety of diagnostic parameters can be made from the waveform recordings, including resistance and compliance of the ventricular catheters and the compliance of the brain. The sensor's clinical applications may be of particular importance to the noninvasive diagnosis of shunt malfunctions with the development of an implantable device.

    Abstract Objective: Prevertebral soft tissue swelling (PSTS) is a known complication of anterior cervical fusion (ACF). Prior studies have shown that perioperative steroids may reduce PSTS after ACF. We retrospectively evaluated the role of perioperative intravenous (IV) corticosteroid administration in minimizing radiographic PSTS measurements in patients undergoing ACF for degenerative disease.
    Methods: Records of 100 consecutive patients undergoing ACF for degenerative disease (Current Procedural Terminology code 63075) from January 2010 through December 2012 by 2 orthopedic spine fellowship-trained surgeons at a single institution were retrospectively reviewed. Patients were included on the basis of specific criteria. They were then separated into comparison and IV steroid groups. Demographic and surgical data were collected. Last, measurements of PSTS, which included PSTS ratio and PSTS index (PSTSI), were obtained from plain radiographs preoperatively and at 3 postoperative time points.
    Results: Eighty patients were included; 26 received IV steroids at the surgeon's discretion (12 intraoperatively, 11 postoperatively and 3 at both time periods). With the exception of a history of prior anterior cervical spine surgery (3.70% comparison vs. 23.08% IV steroid, P = 0.01), there was no statistically significant demographic characteristic. Furthermore, there was no statistically significant surgical characteristic. Last, there was no statistically significant difference between groups at any time point for either PSTS ratio at any level or PSTSI.
    Conclusions: There does not appear to be a role for perioperative IV steroid administration in minimizing radiographic PSTS in patients undergoing ACF for degenerative disease. The relationship between perioperative IV steroid administration and PSTS requires further investigation.

    Abstract Introduction: Treatments for patients with cauda equina injury are limited.
    Methods: In this study, we first used retrograde labeling to determine the relative contributions of cauda equina motor neurons to intrinsic and extrinsic rat tail muscles. Next, we transected cauda equina ventral roots and proceeded to bridge the proximal and distal stumps with either a type I collagen scaffold coated in laminin (CL) or a collagen-laminin scaffold that was also seeded with Schwann cells (CLSC). Regeneration was assessed by way of serial retrograde labeling.
    Results: After accounting for the axonal contributions to intrinsic vs. extrinsic tail muscles, we noted a higher degree of double labeling in the CLSC group (58.0 ± 39.6%) as compared with the CL group (27.8 ± 16.0%; P = 0.02), but not the control group (33.5 ± 18.2%; P = 0.10).
    Discussion: Our findings demonstrate the feasibility of using CLSCs in cauda equina injury repair. Muscle Nerve 57: E78-E84, 2018.

    Abstract Introduction: The rat tail exhibits functional impairment after cauda equina injury. Our goal was to better understand the innervation and roles of muscles that control the tail.
    Methods: Adult rats received either: (1) ventral root injury; (2) caudales nerve injury; or (3) mapping of sacrococcygeal myotomes. Activation of small muscles within the tail itself (intrinsics) was compared with that of larger lumbosacral muscles acting on the tail (extrinsics). Behavioral testing of tail movement was done 1 week later.
    Results: Rats that received ventral root injury exhibited multiple behavioral deficits, whereas rats with injury to caudales nerves maintained more fully preserved tail movement. Mapping studies revealed much broader overlap of myotomes for extrinsic muscles.
    Conclusions: Extrinsic tail muscles play a greater role in tail movement in the rat than their intrinsic counterparts and are innervated by multiple neurological segments. These findings have major implications for future research on cauda equina injury.

    Abstract Background: Oxiracetam may have a modest effect on preventing cognitive decline. Exercise can also enhance cognitive function. This trial aims to investigate the effect of oxiracetam on post-stroke cognitive impairment and explore whether this effect is modified by exercise. Furthermore, the mechanisms that mediate this effect will be investigated through a neural network analysis.
    Methods: This is a multicenter, randomized, double-blind, placebo-controlled phase IV trial. Patients who complained of cognitive decline 3 months after stroke and had a high risk of cognitive decline were eligible. Patients were randomly assigned to receive either 800 mg of oxiracetam or placebo twice daily for 36 weeks. After randomization, a predetermined exercise protocol was provided to each participant, and the degree of physical activity was assessed using wrist actigraphy at 4, 12, 24, and 36 weeks. Resting-state functional MRI was obtained in baseline and 36-week follow-up. Co-primary endpoints are changes in the Mini-Mental State Examination and Clinical Dementia Rating-Sum of Boxes. Secondary endpoints include changes in the NINDS-CSN VCIHS-Neuropsychology Protocol, Euro QoL, patient's global assessment, and functional network connectivity. If there is a significant difference in physical activity between the two groups, the interaction effect between physical activity and the treatment group will be examined. A total of 500 patients were enrolled from February 2018, and the last patient's final follow-up was completed in September 2022.
    Conclusion: This trial is meaningful not only to prove the efficacy of oxiracetam, but also evaluate whether exercise can modify the effects of medication and how cognitive function can be restored. Trial registrationhttp://cris.nih.go.kr (KCT0005137).

    Abstract Sports-related concussion has gained increased prominence, in part due to media coverage of several well-known athletes who have died from consequences of chronic traumatic encephalopathy (CTE). CTE was first described by Martland in 1928 as a syndrome seen in boxers who had experienced significant head trauma from repeated blows. The classic symptoms of impaired cognition, mood, behavior, and motor skills also have been reported in professional football players, and in 2005, the histopathological findings of CTE were first reported in a former National Football League (NFL) player. These finding were similar to Alzheimer's disease in some ways but differed in critical areas such as a predominance of tau protein deposition over amyloid. The pathophysiology is still unknown but involves a history of repeated concussive and subconcussive blows and then a lag period before CTE symptoms become evident. The involvement of excitotoxic amino acids and abnormal microglial activation remain speculative. Early identification and prevention of this disease by reducing repeated blows to the head has become a critical focus of current research.

    Abstract Background: Prescription opioid medications negatively affect postoperative outcomes after lumbar spine surgery. Furthermore, opioid-related overdose death rates in the United States increased by 200% between 2000 and 2014. Thus, alternatives are imperative. Mindfulness-based stress reduction (MBSR), a mind-body therapy, has been associated with improved activity and mood in opioid-using patients with chronic pain. This study assessed whether preoperative MBSR is an effective adjunct to standard postoperative care in adult patients undergoing lumbar spine surgery for degenerative disease.
    Methods: The intervention group underwent a preoperative online MBSR course. The comparison group was matched retrospectively in a 1:1 ratio by age, sex, type of surgery, and preoperative opioid use. Prescription opioid use during hospital admission and at 30 days postoperatively were compared with preoperative use. Thirty-day postoperative patient-reported outcomes for pain, disability, and quality of life were compared with preoperative patient-reported outcomes. Dose-response effect of mindfulness courses was assessed using Mindful Attention Awareness Scale scores.
    Results: In this pilot study, 24 participants were included in each group. Most intervention patients (70.83%) completed 1 session, and the mean Mindful Attention Awareness Scale score was 4.28 ± 0.71 during hospital admission. At 30 days, mean visual analog scale back pain score was lower in the intervention group (P = 0.004) but other patient-reported outcomes did not differ.
    Conclusions: During hospital admission, no significant dose-response effect of mindfulness techniques was found. At 30 days postoperatively, MBSR use was associated with less back pain. Further research is needed to assess the effectiveness of preoperative MBSR on postoperative outcomes in lumbar spine surgery for degenerative disease.

    Abstract Background: Tuberous sclerosis (TS) is a multiorgan neurocutaneous syndrome. Vascular manifestations are often extracranial. There is a paucity of cases involving TS combined with intracranial aneurysms reported in the literature. As a result, treatment has not been well described.
    Case description: We report the case of a 13-month-old female infant with a prior diagnosis of TS that was found to have new onset of left eye ptosis, anisocoria, and papillary mydriasis indicative of left third cranial nerve palsy. A magnetic resonance angiogram (MRA) of the brain revealed a left internal carotid artery (ICA) aneurysm. Endovascular embolization was determined to be the best option for treatment. After a successful balloon test occlusion with neuromonitoring, the left internal carotid artery was sacrificed via coil embolization.
    Conclusions: This is only the third case report of endovascular coil embolization of an intracranial aneurysm in an infant with TS. We report no complications during the procedure, and the patient was discharged with resolving left third cranial nerve palsy. Neither surgical nor endovascular outcomes have been well described in the literature. Follow-up on this patient will be useful for establishing protocols of treatment.

    Abstract Background Prehospital delay is an important contributor to poor outcomes in both acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We aimed to compare the prehospital delay and related factors between AIS and AMI. Methods and Results We identified patients with AIS and AMI who were admitted to the 11 Korean Regional Cardiocerebrovascular Centers via the emergency room between July 2016 and December 2018. Delayed arrival was defined as a prehospital delay of >3 hours, and the generalized linear mixed-effects model was applied to explore the effects of potential predictors on delayed arrival. This study included 17 895 and 8322 patients with AIS and AMI, respectively. The median value of prehospital delay was 6.05 hours in AIS and 3.00 hours in AMI. The use of emergency medical services was the key determinant of delayed arrival in both groups. Previous history, 1-person household, weekday presentation, and interhospital transfer had higher odds of delayed arrival in both groups. Age and sex had no or minimal effects on delayed arrival in AIS; however, age and female sex were associated with higher odds of delayed arrival in AMI. More severe symptoms had lower odds of delayed arrival in AIS, whereas no significant effect was observed in AMI. Off-hour presentation had higher and prehospital awareness had lower odds of delayed arrival; however, the magnitude of their effects differed quantitatively between AIS and AMI. Conclusions The effects of some nonmodifiable and modifiable factors on prehospital delay differed between AIS and AMI. A differentiated strategy might be required to reduce prehospital delay.
