Money Talk and Conduct from Cowries to Bitcoin
Authors: Agha Asif 
Published: October 2017

AbstractWhat role do forms of money play in social life? What kinds of sociocultural variation do they exhibit? What variety of things do people do with varieties of money? How are activities involving money differentiated into registers of money conduct in specific times and places? How are specific forms of money conduct recognized and differentiated from other cultural routines by those who encounter them? It has long been understood that money is intimately linked to varied forms of discursive semiosis through which distinct forms of money are created and endowed with distinct use characteristics; that specific forms of money are readily linked to (or appropriated by) group-specific interests or ideologies; and that differences in types of money conduct readily differentiate social roles and relationships among persons and groups in social history. Yet the role of discursive semiosis in the existence and use of money is not well understood, a lacuna that links most descriptions of “money” to voicing structures (or discursive positionalities) that are not grasped for what they are by those who offer such descriptions (e.g., “speaking like the State” without knowing it). This article clarifies the role of discursive semiosis in the social life of money. It shows that such clarification is a prerequisite on ethnographic answers to the questions listed at the beginning of this abstract. It presents a comparative framework for reasoning about forms of money in forms of life.
Chronotopic Realignments and the Shifting Semiotics and Politics of Visibility in Brazilian Candomblé Activism
Authors: Hartikainen Elina I. 
Published: October 2017

AbstractThis article examines the shifting semiotics and politics of visibility in Brazilian Candomblé activism in the late 2000s in the city of Salvador. It analyses how the use of publicly salient discourses and signs of peace and antiviolence activism by activists from the African diasporic religion Candomblé reconfigured the religion’s practitioners public image from that of politically passive practitioners of “black magic” and self-sacrificing “black mothers” to that of politically active peace and antiviolence activists. I argue that this transformation was effected by a realignment of the general public’s chronotopic orientation toward the religion and its practitioners from a chronotope of concealment to one of political visibility. This shift in chronotopic orientation not only aligned Candomblé practitioners with the social persona of the politically engaged peace activist but also produced a new social persona of a religiously motivated “black mother of peace.”

Published: October 2017

AbstractThe 2014 Farm Bill required farmers and landowners to make a set of one‐time, irrevocable decisions lasting for the duration of the farm bill. The decisions included the choice between three program alternatives with uncertain payments. To aid in making those decisions, the farm bill funded two key educational efforts: (a) the development of two online decision tools and (b) additional funding to support land grant institutions and extension systems to educate farmers through more traditional extension mediums, particularly in‐person meetings. This paper provides an evaluation of both types of farm bill education through two case studies.
On control strategies for avoiding loss of information in non-destructive testing
Authors: Destuynder Philippe , Fabre Caroline 
Published: October 2017

Abstract
This study takes place in the framework of non-destructive testing. Based on energy invariants, one can derive boundary quantities which could help to detect damages in a structure. Since only a small part of a structure is equipped with sensors, a lot of information may be lost through the boundary where there is no sensor. In this article, we study several control strategies in order to focus most of the information contained in the energy invariant used, to the sensors.

Abstract
Lineage-specific Cre Tg mice are widely used to delineate the functions of genes in a tissue-specific manner. Several T-cell-specific promoter cassettes have been developed; however, the activities of those promoters in non-T cells have not been investigated extensively. Here, we report that CD2-Cre-mediated deletion of Erk proteins by generating CD2-Cre × Erk1–/–Erk2flox/flox (Erk∆CD2-Cre) mice results in abnormal cartilage hyperplasia. Histological analysis revealed that this abnormality is caused by aberrant hyperplasia of chondrocytes. The presence of Erk-deficient T cells is not required for this chondroma formation, as it was similarly observed in the absence of T cells in a CD3ε-deficient background. In addition, adoptive transfer of bone marrow cells from Erk∆CD2-Cre mice to wild-type recipients did not cause chondroma formation, suggesting that Erk-deficient non-immune cells are responsible for this abnormality. By tracing Cre-expressed tissues using a ROSA26-STOP-RFP allele, we found that the chondroma emitted RFP fluorescence, indicating that functional Cre is expressed in hyperplastic chondrocytes in Erk∆CD2-Cre mice. Furthermore, RFP+ chondrocytes were also found in an Erk-sufficient background, albeit without aberrant growth. These results suggest that unexpected expression of CD2-driven Cre in chondrocytes generates Erk-deficient chondrocytes, resulting in hyperplastic cartilage formation. Recently, two independent reports showed that CD4-Cre-mediated Ras-Erk signaling ablation led to similar abnormal cartilage formation (Guittard, G., Gallardo, D. L., Li, W. et al. 2017. Unexpected cartilage phenotype in CD4-Cre-conditional SOS-deficient mice. Front. Immunol. 8:343; Wehenkel, M., Corr, M., Guy, C. S. et al. 2017. Extracellular signal-regulated kinase signaling in CD4-expressing cells inhibits osteochondromas. Front. Immunol. 8:482). Together with these reports, our study suggests that an unexpected link exists between T-like cell and chondrocyte lineages during ontogeny.
A Staged Protocol for Circumferential Minimally Invasive Surgical Correction of Adult Spinal Deformity
Authors: Anand Neel , Kong Christopher , Fessler Richard G 
Published: October 2017

Abstract

BACKGROUND
Minimally invasive surgery (MIS) techniques used for management of adult spinal deformity (ASD) aim to decrease the physiological demand on patients and minimize postoperative complications. A circumferential MIS (cMIS) protocol offers the potential to maximize this advantage over standard open approaches, through the concurrent use of multiple MIS techniques.

OBJECTIVE
To demonstrate through a case example the execution of a cMIS protocol for management of an ASD patient with severe deformity.

METHODS
Thorough preoperative assessment, surgical planning, and medical optimization were completed. Deformity correction was performed over 2 stages. During the first stage, interbody fusion was performed via an oblique lateral approach at all levels of the lumbar spine intended to be included in the final construct. The patient was kept as an inpatient and mobilized postoperatively. They were then re-imaged with standing films. The second stage occurred after 3 d and involved percutaneous instrumentation of all levels. Posterior fusion of the thoracic levels was achieved through decortication of pars and facets. These areas were accessed through the intermuscular plane established by the percutaneous screws. The patient was mobilizing on their first postoperative day.

RESULTS
In a 66-yr-old female with severe sagittal imbalance and debilitating back pain, effective use of this cMIS protocol allowed for correction of the Cobb angle from 52° to 4° correction of spinopelvic parameters and 13 cm of sagittal vertical axis improvement. No complications were identified by 2 yr postoperative.

CONCLUSION
As a systematization of multiple MIS techniques combined, in a specific and staged manner, this cMIS protocol could provide a safe and effective approach to the management of ASD.

Published: October 2017

Abstract

BACKGROUND
Neurosurgical procedures are necessary at all times of day. Other surgical specialties have examined the effect of surgical start time (SST) on morbidity and mortality; however, a similar study has not been performed for neurosurgical procedures.

OBJECTIVE
To perform a retrospective cohort study describing the association between SST and operative morbidity.

METHODS
We analyzed all patients undergoing neurological surgery between January 1, 2007 and August 1, 2014 at our institution. This study included 15 807 patients. A total of 785 complications were identified through the self-reported morbidity and mortality reports created by faculty and resident neurosurgeons. We used multilevel logistic regression to investigate the association of SST with morbidity.

RESULTS
In multilevel logistic regression, our Baseline model demonstrated that the odds of complication increased by more than 50% for start times between 21:01 and 07:00 (odds ratio [OR] 1.53, 95% confidence interval [CI] 1.03-2.29, P = .04). When accounting for the length of the surgery, the odds of a complication were even greater for later time periods 21:01 to 07:00 (OR 2.16, 95% CI 1.44-3.23, P < .001). The only statistically significant factor that predicted severity of the complication was if the operation was emergent compared to elective (OR 1.70, 95% CI 1.11-2.60, P = .02). An SST between 21:01 and 07:00 substantially contributed when severe complications were isolated (OR 1.61, 95% CI 1.50-2.90, P = .08).

CONCLUSION
Patients with SSTs between 21:01 and 07:00 are at an increased risk of developing morbidity compared to patients with an SST earlier in the day.

Abstract

BACKGROUND
Prior studies have observed similar health-related quality of life (HRQL) in revisions and nonrevision (NR) patients following adult spinal deformity (ASD) correction. However, a novel comparison approach may allow better comparisons in spine outcomes groups.

OBJECTIVE
To determine if ASD revisions for radiographic and implant-related complications undergo a different recovery than NR patients.

METHODS
Inclusion: ASD patients with complete HRQL (Oswestry Disability Index, Short-Form-36 version 2 (SF-36), Scoliosis Research Society [SRS]-22) at baseline, 6 wk, 1 yr, 2 yr. Generated revision groups: nonrevision (NR), revised-complete data (RC; with follow-up 2 yr after revision), and revised-incomplete data (RI; without 2-yr follow-up after revision). In a traditional analysis, analysis of variance (ANOVA) compared baseline HRQLs to follow-up changes. In a novel approach, integrated health state was normalized at baseline using area under curve analysis before ANOVA t-tests compared follow-up statuses.

RESULTS
Two hundred fifty-eight patients were included with 50 undergoing reoperations (19.4%). Rod fractures (n = 15) and proximal joint kyphosis (n = 9) were most common. In standard HRQL analysis, comparing RC index surgery and RC revision surgery HRQLS revealed no significant differences throughout the 2-yr follow-up from either the initial index or revision procedure. Using normalized HRQL/integrated health state, RI displayed worse scores in SF-36 Physical Component Score, SRS activity, and SRS appearance relative to NR (P < .05), indicating less improvement over the 2-yr period. RC were significantly worse than RI in SF-36 Mental Component Score, SRS mental, SRS satisfaction, and SRS total (P < .05).

CONCLUSION
ASD patients indicated for revisions for radiographic and implant-related complications differ significantly in their overall 2-yr recovery compared to NR, using a normalized integrated health state method. Traditional methods for analyzing revision patients' recovery kinetics may overlook delayed improvements.
Head and Neck: Skull Base Imaging
Authors: Hudgins Patricia A , Baugnon Kristen L 
Published: October 2017

Abstract
There are a myriad of head and neck pathologies that extend from the extracranial to the intracranial compartment, traversing the skull base, and knowledge of the imaging appearance of this pathology is critical to practicing neurosurgeons. This article reviews some of the important inflammatory or acquired head and neck pathology along the skull base, neoplastic skull base lesions, and the intracranial extension of head and neck malignancy. Focus will be on the relevant anatomy, appropriate imaging protocols to evaluate these processes, as well as the differentiating imaging findings on computed tomography and magnetic resonance imaging.
Novel Findings in Obstetric Brachial Plexus Palsy: A Study of Corpus Callosum Volumetry and Resting-State Functional Magnetic Resonance Imaging of Sensorimotor Network

Published: October 2017

Abstract

BACKGROUND
The response of the brain to obstetric brachial plexus palsy (OBPP) is not clearly understood. We propose that even a peripheral insult at the developmental stage may result in changes in the volume of white matter of the brain, which we studied using corpus callosum volumetry and resting-state functional magnetic resonance imaging (rsfMRI) of sensorimotor network.

OBJECTIVE
To study the central neural effects in OBPP.

METHODS
We performed an MRI study on a cohort of 14 children who had OBPP and 14 healthy controls. The mean age of the test subjects was 10.07 ± 1.22 yr (95% confidence interval). Corpus callosum volumetry was compared with that of age-matched healthy subjects. Hofer and Frahm segmentation was used. Resting-state fMRI data were analyzed using the FSL software (FMRIB Software Library v5.0, Oxford, United Kingdom), and group analysis of the sensorimotor network was performed.

RESULTS
Statistical analysis of corpus callosum volume revealed significant differences between the OBPP cohort and healthy controls, especially in the motor association areas. Independent t-test revealed statistically significant volume loss in segments I (prefrontal), II (premotor), and IV (primary sensory area). rsfMRI of sensorimotor network showed decreased activation in the test hemisphere (the side contralateral to the injured brachial plexus) and also decreased activation in the ipsilateral hemisphere, when compared with healthy controls.

CONCLUSION
OBPP occurs in an immature brain and causes central cortical changes. There is secondary corpus callosum atrophy which may be due to retrograde transneuronal degeneration. This in turn may result in disruption of interhemispheric coactivation and consequent reduction in activation of sensorimotor network even in the ipsilateral hemisphere.
Current State of the Surgical Treatment of Terminal Neuromas

Published: October 2017

Abstract
Painful terminal neuromas resulting from nerve injury following amputation are common. However, there is currently no universally accepted gold standard of treatment for this condition. A comprehensive literature review is presented on the treatment of terminal neuromas. Four categories of terminal neuroma surgical procedures are assessed: epineurial closure; nerve transposition with implantation; neurorrhaphy, and alternate target reinnervation. Significant patient and case studies are highlighted in each section, focusing on surgical technique and patient outcome metrics. Studies presented consisted of a PubMed search for “terminal neuromas,” without year limitation. The current available research supports the use of implantation into muscle for the surgical treatment of terminal neuromas. However, this technique has several fundamental flaws that limit its utility, as it does not address the underlying physiology behind neuroma formation. Regenerative peripheral nerve interfaces and targeted muscle reinnervation are 2 techniques that seem to offer the most promise in preventing and treating terminal neuroma formation. Both techniques are also capable of generating control signals which can be used for both motor and sensory prosthetic control. Such technology has the potential to lead to the future restoration of lost limb function in amputees. Further clinical research employing larger patient groups with high-quality control groups and reproducible outcome measures is needed to determine the most effective and beneficial surgical treatment for terminal neuromas. Primary focus should be placed on investigating techniques that most closely approximate the theoretically ideal neuroma treatment, including targeted muscle reinnervation and regenerative peripheral nerve interfaces.

Abstract
Currently, only presumptive diagnosis of chronic traumatic encephalopathy (CTE) can be made in living patients. We present a modality that may be instrumental to the definitive diagnosis of CTE in living patients based on brain autopsy confirmation of [F-18]FDDNP-PET findings in an American football player with CTE. [F-18]FDDNP-PET imaging was performed 52 mo before the subject's death. Relative distribution volume parametric images and binding values were determined for cortical and subcortical regions of interest. Upon death, the brain was examined to identify the topographic distribution of neurodegenerative changes. Correlation between neuropathology and [F-18]FDDNP-PET binding patterns was performed using Spearman rank-order correlation. Mood, behavioral, motor, and cognitive changes were consistent with chronic traumatic myeloencephalopathy with a 22-yr lifetime risk exposure to American football. There were tau, amyloid, and TDP-43 neuropathological substrates in the brain with a differential topographically selective distribution. [F-18]FDDNP-PET binding levels correlated with brain tau deposition (rs = 0.59, P = .02), with highest relative distribution volumes in the parasagittal and paraventricular regions of the brain and the brain stem. No correlation with amyloid or TDP-43 deposition was observed. [F-18]FDDNP-PET signals may be consistent with neuropathological patterns of tau deposition in CTE, involving areas that receive the maximal shearing, angular–rotational acceleration–deceleration forces in American football players, consistent with distinctive and differential topographic vulnerability and selectivity of CTE beyond brain cortices, also involving midbrain and limbic areas. Future studies are warranted to determine whether differential and selective [F-18]FDDNP-PET may be useful in establishing a diagnosis of CTE in at-risk patients.
Management of Odontoid Fractures in the Elderly: A Review of the Literature and an Evidence-Based Treatment Algorithm
Authors: Iyer Sravisht , Hurlbert R John , Albert Todd J 
Published: October 2017

Abstract
Odontoid fractures are the most common fracture of the axis and the most common cervical spine fracture in patients over 65. Despite their frequency, there is considerable ambiguity regarding optimal management strategies for these fractures in the elderly. Poor bone health and medical comorbidities contribute to increased surgical risk in this population; however, nonoperative management is associated with a risk of nonunion or fibrous union. We provide a review of the existing literature and discuss the classification and evaluation of odontoid fractures. The merits of operative vs nonoperative management, fibrous union, and the choice of operative approach in elderly patients are discussed. A treatment algorithm is presented based on the available literature. We believe that type I and type III odontoid fractures can be managed in a collar in most cases. Type II fractures with any additonal risk factors for nonunion (displacement, comminution, etc) should be considered for surgical management. However, the risks of surgery in an elderly population must be carefully considered on a case-by-case basis. In a frail elderly patient, a fibrous nonunion with close follow-up is an acceptable outcome. If operative management is chosen, a posterior approach is should be chosen when fracture- or patient-related factors make an anterior approach challenging. The high levels of morbidity and mortality associated with odontoid fractures should encourage all providers to pursue medical co-management and optimization of bone health following diagnosis.

Authors: Duan Yifei , Wright James , Wright Christina , Shammassian Berje , Tatsuoka Curtis , Bambakidis Nicholas 
Published: October 2017

Abstract

BACKGROUND
A reliable method to specifically identify low vasospasm risk in aneurysmal subarachnoid hemorrhage (aSAH) patients has not been previously proposed.

OBJECTIVE
To develop a clinical algorithm using admission aSAH clinical severity and subarachnoid blood distribution to identify patients at low risk of clinical vasospasm.

METHODS
Clinical severities, admission noncontrasted head computerized tomography (CT) scan, and incidences of vasospasm among 291 aSAH patients treated at our institution were evaluated. Admission head CTs were assessed for distributions of cisternal and ventricular blood. Patients with the following 4 criteria experienced considerably lower risk of vasospasm: (1) Hunt Hess grade 1 to 2, (2) Lack of thick subarachnoid blood filling 2 adjacent cisterns, (3) Lack of thick interhemispheric blood, and (4) Lack of biventricular intraventricular hemorrhage.

RESULTS
One hundred thirty-three patients (45.7%) developed cerebral vasospasm. Hunt Hess grade greater than 2 (odds ratio [OR] 4.52, 95% confidence interval [CI] 2.74-7.46), adjacent cistern blood (OR 4.1, 95% CI 2.51-6.7), interhemispheric thick blood (OR 5.72, 95% CI 3.41-9.59), and biventricular intraventricular hemorrhage (OR 1.92, 95% CI 1.19-3.02) were significant risk factors. Application of our algorithm yielded a sensitivity of 29%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 54.5%, which was superior compared to metrics from current institutional practice criteria. Inter-rater agreement was substantial at mean kappa = 0.75.

CONCLUSION
Application of our novel clinical algorithm produced successful identification of aSAH patients who experience zero risk of clinical vasospasm. Our algorithm is simple to apply with high reliability and is superior to currently available clinical and radiographic metrics.
