OBJECTIVEWith the costs related to the United States medical system constantly rising, efforts are being made to turn traditional inpatient procedures into outpatient same-day surgeries. In this study the authors looked at the various comorbidities and perioperative complications and their impact on readmission rates of patients undergoing outpatient versus inpatient 3- and 4-level anterior cervical discectomy and fusion (ACDF).METHODSThis was a retrospective study of 337 3- and 4- level ACDF procedures in 332 patients (5 patients had both primary and revision surgeries that were included in this total of 337 procedures) between May 2012 and June 2017. In total, 331 procedures were analyzed, as 6 patients were lost to follow-up. Outpatient surgery was performed for 299 procedures (102 4-level procedures and 197 3-level procedures), and inpatient surgery was performed for 32 procedures (11 4-level procedures and 21 3-level procedures). Age, sex, comorbidities, number of fusion levels, pain level, and perioperative complications were compared between both cohorts.RESULTSAnalysis was performed for 331 3- and 4-level ACDF procedures done at 6 different hospitals. The overall 30-day readmission rate was 1.2% (outpatient 3 [1.0%] vs inpatient 1 [3.1%], p = 0.847). Outpatients had increased readmission risk, with comorbidities of coronary artery disease (OR 1.058, p = 0.039), autoimmune disease (OR 1.142, p = 0.006), diabetes (OR 1.056, p = 0.001), and chronic kidney disease (OR 0.933, p = 0.035). Perioperative complications of delirium (OR 2.709, p < 0.001) and surgical site infection (OR 2.709, p < 0.001) were associated with increased risk of 30-day hospital readmission in outpatients compared to inpatients.CONCLUSIONSThis study demonstrates the safety and effectiveness of 3- and 4-level ACDF surgery, although various comorbidities and perioperative complications may lead to higher readmission rates. Patient selection for outpatient 3- and 4-level ACDF cases might play a role in the safety of performing these procedures in the ambulatory setting, but further studies are needed to accurately identify which factors are most pertinent for appropriate selection.

OBJECTIVEIntraspinal anomalies associated with congenital scoliosis (CS) complicate the decision-making process for spinal correction surgery in CS patients. Recently, deformity correction surgery without prior prophylactic neurological intervention has been recognized to be safe in CS patients with intact or stable neurological status. However, no case-control study has identified the surgical outcomes and risks of spinal correction surgery in this patient population. The authors sought to investigate the safety and efficacy of spinal correction surgery for CS associated with untreated intraspinal anomalies (split cord malformation [SCM], tethered cord, and/or syringomyelia) with intact or stable neurological status.METHODSA group of CS patients with intraspinal anomalies (CS+IA) and another group of CS patients without intraspinal anomalies (CS-IA) undergoing 1-stage posterior correction surgery were retrospectively reviewed. The radiographic and clinical outcomes and postoperative complications were compared between the 2 groups.RESULTSThere were 57 patients in the CS+IA group and 184 patients in the CS-IA group. No significant difference was observed in age, sex, spinal curve pattern, main Cobb angle, and flexibility of the main curve between the 2 groups (p > 0.05 for all). The postoperative correction rates of the major curve were comparable between the 2 groups (53.5% vs 55.7% for the CS+IA and CS-IA groups, respectively, p > 0.05). No significant difference was observed in the incidence of either implant-related or neurological complications between 2 groups. No patients in the CS+IA group developed neurological complications, whereas 1 patient in the CS-IA group experienced transient weakness of the left lower extremity after surgery.CONCLUSIONSCoexisting intraspinal anomalies (SCM, tethered cord, and/or syringomyelia) in CS patients with normal or stable neurological status do not significantly increase the risk of neurological complications of correction surgery. Prophylactic neurosurgical intervention for intraspinal anomalies before correction surgery might be unnecessary for these patients.

Published: April 2019

OBJECTIVESagittal imbalance and loss of lumbar lordosis are the main drivers of functional disability in adult degenerative scoliosis. The main limitations of the classic posterior lumbar interbody fusion technique are increased risk of neurological injury and suboptimal correction of the segmental lordosis. Here, the authors describe the radiological results of a modified posterior lumbar interbody fusion and compare the results with a historical cohort of patients.METHODSEighty-two consecutive patients underwent surgical treatment for degenerative scoliosis/kyphosis in a single tertiary referral center for complex spinal surgery. Fifty-five patients were treated using the classic multilevel posterior lumbar interbody fusion (MPLIF) technique and 27 were treated using the modified MPLIF technique to include a release of the anterior longitudinal ligament (ALL) and the annulus. A radiographic review of both series of patients was performed by two independent observers. Functional outcomes were obtained, and patients were registered in the European Spine Tango registry.RESULTSThe mean L4–5 disc angle increased by 3.14° in the classic MPLIF group and by 12.83° in MPLIF plus ALL and annulus release group. The mean lumbar lordosis increased by 15.23° in the first group and by 25.17° in the second group. The L4–S1 lordosis increased on average by 4.92° in the classic MPLIF group and increased by a mean of 23.7° in the MPLIF plus ALL release group when both L4–5 and L5–S1 segments were addressed. There were significant improvements in the Core Outcome Measures Index and EQ-5D score in both groups (p < 0.001). There were no vascular or neurological injuries observed in either group.CONCLUSIONSThe authors’ preliminary results suggest that more correction can be achieved at the disc level using posterior-based ALL and annulus release in conjunction with posterior lumbar interbody fusion. They demonstrate that ALL and annulus release can be performed safely using a posterior-only approach with minimal risk of vascular injury. However, the authors recommend that this approach should only be used by surgeons with considerable experience in anterior and posterior spinal surgery.

OBJECTIVELarge experiences with the treatment of pediatric arteriovenous malformations (AVMs) remain relatively rare, with limited data on presentation, treatment, and long-term functional outcomes. Because of the expected long lifespan of children, caregivers are especially interested in outcome measures that assess quality of life. The authors’ intention was to describe the long-term functional outcomes of pediatric patients who undergo AVM surgery and to identify predictors of sustained neurological deficits.METHODSThe authors analyzed a 21-year retrospective cohort of pediatric patients with intracranial AVMs treated with microsurgery at two institutions. The primary outcome was a persistent neurological deficit at last follow-up. Secondary outcome measures included modified Rankin Scale (mRS) score and independent living.RESULTSOverall, 97 patients (mean age 11.1 ± 4.5 years; 56% female) were treated surgically for intracranial AVMs (mean follow-up 77.5 months). Sixty-four patients (66%) presented with hemorrhage, and 45 patients (46%) had neurological deficits at presentation. Radiologically, 39% of lesions were Spetzler-Martin grade II. Thirty-seven patients (38%) with persistent neurological deficits at last follow-up were compared with those without deficits; there were no differences in patient age, presenting Glasgow Coma Scale score, AVM size, surgical blood loss, or duration of follow-up. Multivariate analysis demonstrated that a focal neurological deficit on presentation, AVM size > 3 cm, and lesions in eloquent cortex were independent predictors of persistent neurological deficits at long-term follow-up. Overall, 92% of the children had an mRS score ≤ 2 on long-term follow-up.CONCLUSIONSPediatric patients with AVMs treated with microsurgical resection have good functional and radiological outcomes. There is a high rate (38%) of persistent neurological deficits, which were independently predicted by preoperative deficits, AVMs > 3 cm, and lesions located in eloquent cortex. This information can be useful in counseling families on the likelihood of long-term neurological deficits after cerebral AVM surgery.

Investigations on maladaptive plasticity in the sensorimotor cortex of unilateral upper limb CRPS I patients
Authors: Pfannmöller J. , Strauss S. , Langner I. , Usichenko T. , Lotze M. 
Published: April 2019

Background: Patients with a complex regional pain syndrome (CRPS) in the upper limb show a sensory and motor impairment of the hand. Decreased intra-cortical-inhibition (ICI) of the motor representation of the affected hand muscle and decreased somatosensory hand representation size were related to maladaptive plasticity. Objective: To achieve new insights about CRPS we examined whether these alterations were present in a single cohort. Methods: We used a multi-modal approach comprising behavioral testing, transcranial magnetic stimulation, and high resolution fMRI combined with a new analysis technique for improved neuronal specificity. Results: We found a decreased pinch-grip performance, two-point discrimination on the fingertips, ICI in the motor cortex, and representation size of the hand in Brodmann Area 3b (BA3b) in the somatosensory cortex. Our analysis further showed that correlations with ICI on the non-affected side were absent on the affected side. Conclusions: This study is the first to gather behavioral, neurophysiologic and imaging measurements for one patient cohort and it therefore enables a comprehensive view of collapsed associations of function and representation focused on the hemisphere contralateral to the affected hand.
Influence of power asymmetry, commitment and trust on sme retailers’ performance
Authors: Setyawan Anton , Susila Ihwan , Anindita Sekar 
Published: April 2019

The purpose of this study is to analyze the effect of power asymmetry, commitment and trust to business performance. In a business relation, the role of power asymmetry, commitment and trust are importance to maintain the quality of a relationship. Business performance is an important factor to decide whether a business relation should be continued or terminated. We conducted a survey with traditional SME retailers in Indonesia as the respondents, which were obtained through purposive sampling methods. This study involved 245 SME retailers who have business relation with modern companies as their supplier. We adopted Morgan and Hunt’s (1994) model of relationship marketing for business to business in order to analyze the relationship among companies in business network. The result shows that power asymmetry, commitment and trust have significant, positive effects on business performance. The implication of this study is: power asymmetry between modern companies and SME potentially accelerates their performance, while commitment and trust will provide firm foundation for the companies involved in the business relation. In overall, power asymmetry has impact for firm with lack of bargaining position in business relation, thus instead of being exploited, SME retailers can increase their business performance due to partner’s pressure and demand to their performance.
A Mean-field Approach to Simulating the Merging of Collisionless Stellar Systems Using a Particle-based Method
Authors: Hozumi Shunsuke , Iwasawa Masaki , Nitadori Keigo 
Published: April 2019

Abstract
We present a mean-field approach to simulating merging processes of two spherical collisionless stellar systems. This approach is realized with a self-consistent field (SCF) method in which the full spatial dependence of the density and potential of a system is expanded in a set of basis functions for solving Poisson’s equation. To apply this SCF method to a merging situation where two systems are moving in space, we assign the expansion center to the center of mass of each system, the position of which is followed by a massless particle placed at that position initially. Merging simulations over a wide range of impact parameters are performed using both an SCF code developed here and a tree code. The results of each simulation produced by the two codes show excellent agreement in the evolving morphology of the merging systems and in the density and velocity dispersion profiles of the merged systems. However, comparing the results generated by the tree code with those obtained with the softening-free SCF code, we found that in large impact parameter cases, a softening length of the Plummer type introduced in the tree code has an effect of advancing the orbital phase of the two systems in the merging process at late times. We demonstrate that the faster orbital phase originates from the larger convergence length to the pure Newtonian force. Other application problems suitable to the current SCF code are also discussed.
Identifying El Niño–Southern Oscillation influences on rainfall with classification models: implications for water resource management of Sri Lanka
Authors: De Silva M. Thushara , Hornberger George M. 
Published: April 2019

Abstract. Seasonal to annual forecasts of precipitation patterns are very
important for water infrastructure management. In particular, such forecasts
can be used to inform decisions about the operation of multipurpose
reservoir systems in the face of changing climate conditions. Success in
making useful forecasts is often achieved by considering climate
teleconnections such as the El Niño–Southern Oscillation (ENSO) and Indian
Ocean Dipole (IOD) as related to sea surface temperature variations. We
present a statistical analysis to explore the utility of using rainfall
relationships in Sri Lanka with ENSO and IOD to predict rainfall to the Mahaweli
and Kelani River basins of the country. Forecasting of rainfall as the classes flood, drought, and normal is helpful
for water resource management decision-making. Results of these models
give better accuracy than a prediction of absolute values. Quadratic
discrimination analysis (QDA) and classification tree models are used to
identify the patterns of rainfall classes with respect to ENSO and IOD
indices. Ensemble modeling tool Random Forest is also used to predict the
rainfall classes as drought and not drought with higher skill. These models
can be used to forecast the areal rainfall using predicted climate indices.
Results from these models are not very accurate; however, the patterns
recognized provide useful input to water resource managers as they plan for
adaptation of agriculture and energy sectors in response to climate variability.
Simulating intersection angles between conjugate faults in sea ice with different viscous–plastic rheologies
Authors: Ringeisen Damien , Losch Martin , Tremblay L. Bruno , Hutter Nils 
Published: April 2019

Abstract. Recent high-resolution pan-Arctic sea ice simulations show
fracture patterns (linear kinematic features or LKFs) that are typical of
granular materials but with wider fracture angles than those observed in
high-resolution satellite images. Motivated by this, ice fracture is
investigated in a simple uni-axial loading test using two different
viscous–plastic (VP) rheologies: one with an elliptical yield curve and a
normal flow rule and one with a Coulombic yield curve and a normal flow rule
that applies only to the elliptical cap. With the standard VP rheology, it is
not possible to simulate fracture angles smaller than 30∘. Further,
the standard VP model is not consistent with the behavior of granular
material such as sea ice because (1) the fracture angle increases with ice
shear strength; (2) the divergence along the fracture lines (or LKFs) is
uniquely defined by the shear strength of the material with divergence for
high shear strength and convergent with low shear strength; (3) the angle of
fracture depends on the confining pressure with more convergence as the
confining pressure increases. This behavior of the VP model is connected to
the convexity of the yield curve together with use of a normal flow rule. In
the Coulombic model, the angle of fracture is smaller (θ=23∘)
and grossly consistent with observations. The solution, however, is unstable
when the compressive stress is too large because of non-differentiable
corners between the straight limbs of the Coulombic yield curve and the
elliptical cap. The results suggest that, although at first sight the large-scale patterns of LKFs simulated with a VP sea ice model appear to be
realistic, the elliptical yield curve with a normal flow rule is not
consistent with the notion of sea ice as a pressure-sensitive and dilatant
granular material.
