Abstract
This study describes the generation and testing of a reference rainfall product created from field campaign datasets collected during the NASA Global Precipitation Measurement (GPM) mission Ground Validation Iowa Flood Studies (IFloodS) experiment. The study evaluates ground-based radar rainfall (RR) products acquired during IFloodS in the context of building the reference rainfall product. The purpose of IFloodS was not only to attain a high-quality ground-based reference for the validation of satellite rainfall estimates but also to enhance understanding of flood-related rainfall processes and the predictability of flood forecasting. We assessed the six RR estimates (IFC, Q2, CSU-DP, NWS-DP, Stage IV, and Q2-Corrected) using data from rain gauge and disdrometer networks that were located in the broader field campaign area of central and northeastern Iowa. We performed the analyses with respect to time scales ranging from 1 h to the entire campaign period in order to compare the capabilities of each RR product and to characterize the error structure at scales that are frequently used in hydrologic applications. The evaluation results show that the Stage IV estimates perform superior to other estimates, demonstrating the need for gauge-based bias corrections of radar-only products. This correction should account for each product’s algorithm-dependent error structure that can be used to build unbiased rainfall products for the campaign reference. We characterized the statistical error structures (e.g., systematic and random components) of each RR estimate and used them for the generation of a campaign reference rainfall product. To assess the hydrologic utility of the reference product, we performed hydrologic simulations driven by the reference product over the Turkey River basin. The comparison of hydrologic simulation results demonstrates that the campaign reference product performs better than Stage IV in streamflow generation.

Background Older people are at greater risk of both physical impairments and cognitive decline. Although previous studies have examined whether visual and cognitive impairments are associated, findings have been mixed with cognitive performance only crudely assessed. Nonetheless, it remains possible that this association becomes stronger with age. Accordingly, in the present study, we tested the hypothesis that older people with visual impairments have poorer cognitive performance than healthy controls. To this end, we employed validated tools to assess both visual-related and visual-unrelated cognitive skills. Methods A total of 30 older adults (mean age: M = 63.98 years, 30% females) with poor vision (logMAR value 1.0 or higher) and 30 gender- and age-matched healthy controls with no visual impairments (logMAR value 0.2 or lower) took part in this cross-sectional study. After a careful medical and psychiatric examination, participants underwent thorough cognitive testing for working and long-term memory and attention. Results Cognitive performance did not differ between those with and without visual impairments, though better cognitive performance scores were associated with higher educational level. Conclusions Among older people, visual impairment was unrelated to cognitive performance. Rather, cognitive function was related to level of education.

Objective The optimal surgical approach for Siewert type II adenocarcinoma of the esophagogastric junction (AEG) is controversial. In this study, we evaluated the outcomes of total gastrectomy for Siewert type II/III AEG via the left thoracic surgical approach that is used at our center. Methods We identified 41 patients with advanced AEG in our retrospective database and analyzed their 3-year survival rate, upper surgical margin, postoperative complications, and index of estimated benefit from lymph node dissection. Results The 3-year overall survival rate of the whole group was 63%, but no difference was observed between Siewert type II and III AEGs. Esophageal exposure and lymphadenectomy were sufficient. Eight patients developed postoperative complications, but none of the patients developed anastomotic leakage. Dissection of lymph node station Nos. 19 and 110 may be necessary for patients with Siewert type II AEG. Multivariate analysis revealed that the cT category was the only independent risk factor. Conclusions Total gastrectomy via an approach from the abdominal cavity into the thoracic cavity may be an optimal surgical technique for advanced Siewert type II AEG.
Financial leverage and competitive strategy of cross-listing firms
Authors: Yang Chi-Lin , Chiang Min-Hsien , Chen Chien-Wei 
Published: October 2018

This study investigates the relationship between financial leverage and competitive strategies based on the investigation into the cross-listing announcements, through which the financial condition of a firm might shape the competition outcome. The empirical evidence shows that cross-listing announcements normally attract positive market responses to cross-listed firms but incur negative market responses to rival firms, especially upon the strategic substitutes competition. Cross-listed firms obtain more positive market responses if their financial leverage is lower, but the firms have no advantages when they are financially constrained. Less leveraged rival firms could weaken the negative impact and even gain positive market responses upon the strategic complements competition. JEL classification: G14, G32, M16

Published: October 2018

Background Migraine with aura is independently associated with increased risk of ischemic stroke, especially in younger subjects. This association might be related to an impairment of cerebral autoregulation, which normally maintains cerebral blood flow independent of arterial blood pressure variations. Methods Patients aged 30–55, fulfilling ICHD-3 beta criteria for migraine with aura, were prospectively enrolled and compared with gender- and age-matched healthy controls without a history of migraine. Patients and controls with a history of stroke or any disease potentially impairing cerebral autoregulation were excluded. We assessed cerebral autoregulation with two different methods: Transfer function analysis, and the correlation coefficient index Mx. The transfer function phase and gain reflect responses of cerebral blood flow velocities to relatively fast fluctuations of arterial blood pressure, whereas Mx also reflects responses to slower arterial blood pressure fluctuations. Results A total of 22 migraine with aura patients (median age [IQR]: 39.5 [12.5] years) and 22 controls (39 [9.75] years) were included. Transfer function parameters and Mx were not different between patients and controls. However, Mx was inversely correlated with age in patients (ρ = −0.567, p = 0.006) and not in controls (ρ = −0.084, p = 0.509). Mx was also inversely correlated with migraine with aura duration (ρ = −0.617, p = 0.002), suggesting improvement of cerebral autoregulation efficiency with disease duration. Conclusions Cerebral autoregulation did not differ between patients and controls aged 30–55. However, cerebral autoregulation efficiency was strongly correlated with migraine with aura duration. Further studies in younger patients are needed to determine whether cerebral autoregulation is impaired early in the course of disease. Trial Registration NCT02708797.

Purpose: To promote understanding of cognitive impairment in multiple sclerosis (MS), recommend optimal screening, monitoring, and treatment strategies, and address barriers to optimal management. Methods: The National MS Society (“Society”) convened experts in cognitive dysfunction (clinicians, researchers, and lay people with MS) to review the published literature, reach consensus on optimal strategies for screening, monitoring, and treating cognitive changes, and propose strategies to address barriers to optimal care. Recommendations: Based on current evidence, the Society makes the following recommendations, endorsed by the Consortium of Multiple Sclerosis Centers and the International Multiple Sclerosis Cognition Society: Increased professional and patient awareness/education about the prevalence, impact, and appropriate management of cognitive symptoms. For adults and children (8+ years of age) with clinical or magnetic resonance imaging (MRI) evidence of neurologic damage consistent with MS: As a minimum, early baseline screening with the Symbol Digit Modalities Test (SDMT) or similarly validated test, when the patient is clinically stable; Annual re-assessment with the same instrument, or more often as needed to (1) detect acute disease activity; (2) assess for treatment effects (e.g. starting/changing a disease-modifying therapy) or for relapse recovery; (3) evaluate progression of cognitive impairment; and/or (4) screen for new-onset cognitive problems. For adults (18+ years): more comprehensive assessment for anyone who tests positive on initial cognitive screening or demonstrates significant cognitive decline, especially if there are concerns about comorbidities or the individual is applying for disability due to cognitive impairment. For children (<18 years): neuropsychological evaluation for any unexplained change in school functioning (academic or behavioral). Remedial interventions/accommodations for adults and children to improve functioning at home, work, or school.

Purpose: To report on the endovascular management of a patient affected by concomitant left common iliac artery and right superficial femoral artery (SFA) pseudoaneurysms after stent positioning. Case Report: A 77-year-old man affected by severe lower limb atherosclerosis was previously treated with iliac and femoropopliteal Supera stenting procedures; he presented to our emergency department because of bilateral severe claudication recurrence, back pain, and right groin region swelling. Angio-computed tomography (CT) depicted 2 pseudoaneurysms of the left common iliac artery and right SFA, due to stent fracture and stent intussusception, respectively. A 2-step endovascular treatment was planned using bilaterally covered stent-grafts to exclude vascular lesions from blood flow. The devices were successfully deployed without any complication. At 1 month, angio-CT confirmed patency of the implanted stent-grafts showing complete pseudoaneurysm exclusion without leaks. Conclusion: Endovascular approach can be a valid option in the treatment of pseudoaneurysms due to stenting procedure complications.
Systematic review of organizational models for intra-arterial treatment of acute ischemic stroke
Authors: Ciccone Alfonso , Berge Eivind , Fischer Urs 
Published: October 2018

Background Intra-arterial treatment of acute ischemic stroke requires changes to acute stroke services since most hospitals do not have on-site intra-arterial treatment facilities. Aim To identify models for delivery of intra-arterial treatment and to compare process performance and clinical and radiological outcomes of the different models. Methods We systematically searched the literature and contacted experts in the field. We performed a qualitative synthesis to identify models, and a quantitative review and meta-analysis of clinical and radiological outcomes under different organizational models. Summary of review The searches retrieved 148 publications, of which 27 were used for the identification and description of models, and 9 for the comparison of the different models. We identified four main models: the mother-ship, drip-and ship, mobile interventionist, and mobile stroke unit models. There were no randomized-controlled trials of the different models, but non-randomized comparisons were possible using data from 8 observational studies and 1 randomized-controlled trial of intra-arterial therapy, of a total of 4127 patients. Comparison between the mother-ship and drip-and-ship models showed no difference in survival (OR 0.81; 95% CI 0.63–1.03), favorable functional outcome (OR 0.96; 95% CI 0.73–1.25), or arterial patency (OR 0.89; 95% CI 0.73–1.08). Conclusions Different organizational models exist for intra-arterial treatment of acute ischemic stroke, but there is insufficient evidence to recommend a particular, universal model. Until one model can be shown to be superior, the choice of model should depend on local factors and patient characteristics.

Background A core outcome set (COS; an agreed, minimum set of outcomes) was needed to address the heterogeneous measurement of outcomes in aphasia treatment research and to facilitate the production of transparent, meaningful, and efficient outcome data. Objective The Research Outcome Measurement in Aphasia (ROMA) consensus statement provides evidence-based recommendations for the measurement of outcomes for adults with post-stroke aphasia within phases I–IV aphasia treatment studies. Methods This statement was informed by a four-year program of research, which comprised investigation of stakeholder-important outcomes using consensus processes, a scoping review of aphasia outcome measurement instruments, and an international consensus meeting. This paper provides an overview of this process and presents the results and recommendations arising from the international consensus meeting. Results Five essential outcome constructs were identified: Language, communication, patient-reported satisfaction with treatment and impact of treatment, emotional wellbeing, and quality of life. Consensus was reached for the following measurement instruments: Language: The Western Aphasia Battery Revised (WAB-R) (74% consensus); emotional wellbeing: General Health Questionnaire (GHQ)-12 (83% consensus); quality of life: Stroke and Aphasia Quality of Life Scale (SAQOL-39) (96% consensus). Consensus was unable to be reached for measures of communication (where multiple measures exist) or patient-reported satisfaction with treatment or impact of treatment (where no measures exist). Discussion Harmonization of the ROMA COS with other core outcome initiatives in stroke rehabilitation is discussed. Ongoing research and consensus processes are outlined. Conclusion The WAB-R, GHQ-12, and SAQOL-39 are recommended to be routinely included within phases I–IV aphasia treatment studies. This consensus statement has been endorsed by the Collaboration of Aphasia Trialists, the British Aphasiology Society, the German Society for Aphasia Research and Therapy, and the Royal College of Speech Language Therapists.

Background and purpose Computed tomography perfusion (CTP) and multiphase CT angiography (mCTA) help selection for endovascular treatment (EVT) in anterior ischemic stroke (AIS). Our aim was to investigate the ability of perfusion maps and collateral score to predict functional outcome after EVT. Patients and methods Patients with M1-middle cerebral artery occlusion, evaluated by mCTA and CTP and treated with EVT within six hours of onset, were enrolled. Perfusion parametric maps of cerebral blood flow (CBF), cerebral blood volume (CBV) and time to maximum of tissue residue function ( Tmax) were generated; areas of altered perfusion were manually outlined to obtain volumes CBFv, CBVv, [Formula: see text] and [Formula: see text]. Diffusion-weighted imaging (DWI) at 24–36 hours was used to manually outline the ischemic core (volume: DWIv). Collateral vessels were assessed on mCTA considering extent and delay of maximal enhancement (six-point scale). Functional outcome was evaluated by modified Rankin Scale score at three months. Volumes in good and poor outcome groups were compared by Wilcoxon rank-sum test t, and their discriminative ability for outcome was determined by receiver operating characteristic analysis. A logistic regression model, including Tmax, CBF and collaterals, was used to differentiate good and poor outcome. Results Seventy-one patients (mean age 75 ± 11 years, range 45–99 years) were included. [Formula: see text], [Formula: see text], CBVv, CBFv and DWIv were statistically different between the two groups. CBF had the best discriminative value for good and poor outcome (area under the curve (AUC) 0.73; 64.5% sensitivity; 74.4% specificity); the logistic regression model might be promising (AUC 0.79, 64.5% sensitivity, 82.1% specificity). Conclusions In patients with AIS, the combined use of CTP and mCTA predicts functional outcome of EVT and might allow better selection.

BackgroundCardiac rehabilitation improves health-related quality of life (HRQoL) and reduces hospitalizations in patients with heart failure, but international uptake of cardiac rehabilitation for heart failure remains low.Design and methodsThe aim of this multicentre randomized trial was to compare the REACH-HF (Rehabilitation EnAblement in CHronicHeart Failure) intervention, a facilitated self-care and home-based cardiac rehabilitation programme to usual care for adults with heart failure with reduced ejection fraction (HFrEF). The study primary hypothesis was that the addition of the REACH-HF intervention to usual care would improve disease-specific HRQoL (Minnesota Living with Heart Failure questionnaire (MLHFQ)) at 12 months compared with usual care alone.ResultsThe study recruited 216 participants, predominantly men (78%), with an average age of 70 years and mean left ventricular ejection fraction of 34%. Overall, 185 (86%) participants provided data for the primary outcome. At 12 months, there was a significant and clinically meaningful between-group difference in the MLHFQ score of –5.7 points (95% confidence interval –10.6 to –0.7) in favour of the REACH-HF intervention group ( p = 0.025). With the exception of patient self-care ( p < 0.001) there was no significant difference in other secondary outcomes, including clinical events ( p > 0.05) at follow-up compared with usual care. The mean cost of the REACH-HF intervention was £418 per participant.ConclusionsThe novel REACH-HF home-based facilitated intervention for HFrEF was clinically superior in disease-specific HRQoL at 12 months and offers an affordable alternative to traditional centre-based programmes to address current low cardiac rehabilitation uptake rates for heart failure.
The influence of a microprocessor-controlled hydraulic ankle on the kinetic symmetry of trans-tibial amputees during ramp walking: A case series
Authors: McGrath Michael , Laszczak Piotr , Zahedi Saeed , Moser David 
Published: October 2018

Introduction Asymmetrical limb loading is believed to cause health problems for lower limb amputees and is exacerbated when walking on slopes. Hydraulically damped ankle-feet improve ground compliance on slopes compared to conventional prosthetic feet. Microprocessor-controlled hydraulic ankle-feet provide further adaptation by dynamically adjusting viscoelastic damping properties. Method Using a case series design, gait analysis was performed with four trans-tibial amputees. There were two walking conditions (ramp ascent and descent) and two prosthetic foot conditions (microprocessor-control on and off – MPF-on and MPF-off). Total support moment integral ([Formula: see text]) and degree-of-asymmetry were compared across foot conditions. Results During ramp descent, the transition of prosthetic ankle moment from dorsiflexion to plantarflexion occurred earlier in stance phase with MPF-on, slowing the angular velocity of the shank. During ramp ascent, the MPF-on dorsiflexion/plantarflexion moment transition occurred later, meaning less resistance to shank rotation in early stance and increasing walking speed by up to 6%. For both slope conditions, sound limb [Formula: see text] was universally decreased with MPF-on (4–13% descent, 3–11% ascent). Discussion Microprocessor-control of hydraulic ankle-feet reduced the total loading of the sound limb joints, for both walking conditions, for all participants. This may have beneficial consequences for long-term joint health and walking efficiency.
