Authors: Liakopoulos Oliver , Slottosch Ingo , Deppe Antje , Choi Yeong-Hoon , Madershahian Navid , Wahlers Thorsten , Kuhn Elmar 
Published: December 2017

Background Choice of cardioplegic solution plays a pivotal role in special subgroups of patients referred for on-pump cardiac surgery. This retrospective analysis aimed to assess the impact of intermittent warm (Calafiore, Cala) versus intermittent cold blood cardioplegia (Buckberg, Buck) in patients referred to coronary artery bypass graft (CABG) surgery due to acute coronary syndromes (ACS).
Methods From 2008 to 2015, all consecutive patients undergoing urgent on-pump CABG surgery due to ACS (n = 950) were retrospectively analyzed. Intraoperative cardiac arrest was achieved using Buck (n = 273) or Cala (n = 677). Patients were compared regarding clinical outcomes and perioperative myocardial injury (PMI). Propensity score matching was performed to control for differences in preoperative patient characteristics.
Results Prevalences of left main stenosis >50%, COPD, and advanced New York Heart Association (NYHA) class were higher for intermittent warm blood cardioplegia (IWC)-patients while more Buck-patients had preoperative intra-aortic balloon pump (IABP) and redo procedures. Buck-patients needed more intraoperative defibrillations and showed longer cardiopulmonary bypass (CPB) and aortic clamping times. 30-day all-cause mortality (10.6 versus 9.3%), major adverse cardiac events (MACE) (52.7 versus 48.6%), and PMI (50.5 versus 55.7%; all p > 0.05) rates were comparable for Buck- and Cala-patients. Propensity score matching resulted in equal group sizes (n = 212 each) and balanced distribution of preoperative covariates. Although more Buck-patients still needed inotropic support >24 hours postoperatively (25.7 versus 14.7%; p = 0.005) compared with Cala-group, outcome variables of interest did not differ between treatment groups (30-day mortality: 7.5 versus 9.0%; MACE: 49.5 versus 40.6%; PMI: 48.1 versus 37.3%; all p > 0.05).
Conclusion Buckberg and Calafiore cardioplegia offer comparable myocardial protection and similar postoperative results in patients undergoing CABG surgery due to ACS.
Robust processing of the Dutch verb phrase
Authors: Van Eecke Paul 
Published: December 2017

Abstract
The Dutch verb phrase (VP) is notorious for its syntactic intricacies. There are
three main reasons why it is difficult to robustly handle its complexity in a
processing model. First of all, a single VP can contain multiple modal
auxiliaries (‘modal stacking’). Second, perfect auxiliaries can not only take a
past participle as their argument but also a modal auxiliary in the infinitive
form. Finally, there are various word orders in which the verb forms can appear.
The first part of this paper presents a fully operational precision processing
model of the Dutch VP in Fluid Construction Grammar. The model shows that the
aforementioned challenges can be overcome by carefully managing the hierarchical
relations between the elements of the VP. The second part introduces a robust
comprehension method, which can process VPs containing morphological and word
order errors. This method allows in many cases to recover the intended meaning
of an erroneous VP, as well as to correct its form, using a strategy that
exploits the deep semantic analyses and the bidirectional nature of the
model.
The colour of Dutch
Authors: Jaspers Jürgen 
Published: December 2017

AbstractMany studies in recent years identify and discuss Dutch ethnolects. Generally this work takes linguistic phenomena as directly reflective of speakers’ ethnic identity. But if ethnicity is an inherent speaker feature, the absence of white ethnolect descriptions is difficult to explain. In this paper, therefore, I wish to judge the appeal of the notion of ethnolect against itsusefulness for explaining language use. I argue that ethnolect can usefully label everyday ethnicisations of language, but that such evaluations generally compress a more complex reality in which so-called ethnolectal features are recruited for other purposes than (un)marking one’s ascribed ethnicity. Crucial to unpacking this reality is the distinction of an intermediary step, the construction of interactional stance, between the use of linguistic features and their association with common-sense identity categories.
The attrition of Turkish as a third language
Authors: Yildiz Yasemin , Koyuncuoglu Hande 
Published: December 2017

AbstractThis longitudinal study investigates an English-French-Turkish-speaking seven-years-old female child’s repertoire combining two Indo-European languages, English and French, and Turkish, which is an Altaic language. Language attrition has mostly focused on first language (L1) attrition, and to a lesser extent on second language (L2) attrition. Third language (L3) attrition, however, has been mostly overlooked, and more attention has gone to adult language attrition after migration or after institutional language learning. Most research has in addition focused on only a subset of target languages (TL). This paper therefore addresses the attrition of child L3 (Turkish) attrition ‘after remigration’. The findings show selective regression with structurally assigned morphology and confirm the findings of previous studies showing that the younger the informant, the more attrition is likely to occur.
Procedural repetition in task-based interaction among young EFL learners
Authors: Lázaro-Ibarrola Amparo , Hidalgo María Ángeles 
Published: December 2017

Abstract
Interactive tasks are valuable tools for L2 learners and have long made their way into language lessons. Among the different task conditions, only few studies have dealt with procedural repetition, which consists of repeating the same task type with different contents and which is frequently used in schools. In this study we explore the effects of procedural repetition on the oral interactions of ten pairs of English learners (age 11) who had to repeat a task three times. Their negotiation strategies and general performance (accuracy, fluency and complexity) were analysed. Results show that, in the third repetition, the amount of confirmation checks and repetitions decreased significantly and accuracy timidly improved. All other aspects remained unaffected. The pedagogical implications of these results are also discussed.

Authors: Chen Y L , Han L 
Published: December 2017

Abstract
Most of the pipelines of oil and gas pipelines in our country have been for more than 25 years. These pipes are buried underground and was difficult to daily test. In addition, it was vulnerable to environmental, corrosion and natural disasters, So there is a hidden nature of accidents. The rapid development of urbanization, population accumulation, dense building and insufficient safety range are all the reasons for the frequent accidents of oil and gas pipelines. Therefore, to appraise and know the safe condition of the city various regions oil and gas pipelines is vital significant. In order to ensure the safety of oil and gas pipeline city, this paper defines the connotation of oil and gas pipeline city vulnerability according to the previous research on vulnerability. Then from three perspectives of environment, structure and behavior, based on the analytical paradigm of “structure—vulnerability conduct—performance” about oil and gas, the influential indicators of vulnerable oil and gas pipelines were analysed, the vulnerability mechanism framework of Oil and gas pipeline city was also constructed. Finally, the paper proposed the regulating strategy of the vulnerability of the oil and gas pipeline city to decrease its vulnerability index, which can be realize the city’s vulnerability evaluation and provides new ideas for the sustainable development of the city.

Authors: Xiang Xiaoling , An Ruopeng , Oh Hyunsung 
Published: December 2017

Abstract

Objectives
This study aimed to examine the bidirectional relationship between depressive symptoms and homebound status among older adults.

Method
The study sample included 7,603 community-dwelling older adults from the National Health and Aging Trends Study. A bivariate latent state-trait model of depressive symptoms and homebound status was estimated via structural equation modeling.

Results
The model fit the data well (Root Mean Square Error of Approximation = .02, Comparative Fit Index = .97, Standardized Root Mean Square Residual = .06). The relationship between homebound status and depressive symptoms can be decomposed into three parts: a moderate correlation between the stable trait components (r = .56, p &lt;.001); a contemporary association of the state components (b = .17, p &lt;.001); and bidirectional lagged effects between the state components. Change in homebound status was as a stronger predictor of depressive symptoms (b = .19, p &lt; .001) than change in depressive symptoms was of homebound status (b = .06, p &lt; .001; test of difference: Δ scaled χ2(1) = 24.2, p &lt; .001).

Discussion
Homebound status and depressive symptoms form a feedback loop to influence each other. Improving the outdoor mobility of older adults may have immediate benefits for reducing depressive symptoms.
Dose effect of patient–care team communication via secure portal messaging on glucose and blood pressure control
Authors: Price-Haywood Eboni G , Luo Qingyang , Monlezun Dominique 
Published: December 2017

AbstractObjectivesOrganizational strategies for implementing eHealth tools influence patient and provider use of portal technology. This study examines whether the intensity of bidirectional secure portal messaging is associated with improved clinical outcomes.Material and MethodsThis is a retrospective cohort analysis of 101 019 patients with diabetes or hypertension (11 138 active portal users) who received primary care within the Ochsner Health System between 2012 and 2014. Propensity score–adjusted multivariable fixed effects regression panel analysis was used to examine associations between intensity of “medical advice” portal messaging and glucose/blood pressure control.ResultsMost portal users rarely used medical advice messaging. A higher proportion of patients who were age 50 years and older, female, white non-Hispanic, and with co-morbid diabetes and hypertension had higher frequency and intensity of medical advice messaging. Study findings revealed a dose-response effect of the intensity of messaging on glucose control, whereby, compared to nonportal users, each level of messaging among portal users was associated with greater decreases in HbA1c (β estimate [95% CI]: none −0.28 (−0.34 to −0.22); low −0.28 (−0.32 to −0.24); medium −0.41 (−0.52 to −0.31); high −0.43 (−0.60 to −0.27), all P ≤ .001). There was no observed effect on blood pressure.ConclusionsThe digital divide exists not only between portal users and nonusers but also among portal users. Research exploring the relationship between intensity of bidirectional secure messaging and health outcomes for a broader scope of chronic conditions is needed. Future implementation research must also elucidate best practices that enhance not only the use of portals by patients and providers, but how they use portals.
A 2–3 billion year old major merger paradigm for the Andromeda galaxy and its outskirts
Authors: Hammer F , Yang Y B , Wang J L , Ibata R , Flores H , Puech M 
Published: December 2017

Abstract
Recent observations of our neighbouring galaxy M31 have revealed that its disc was shaped by widespread events. The evidence for this includes the high dispersion (V/σ ≤ 3) of stars older than 2 Gyr, and a global star formation episode, 2–4 Gyr ago. Using the modern hydrodynamical code, gizmo, we have performed 300 high-resolution simulations to explore the extent to which these observed properties can be explained by a single merger. We find that the observed M31 disc resembles models having experienced a 4:1 merger, in which the nuclei coalesced 1.8–3 Gyr ago, and where the first passage took place 7–10 Gyr ago at a large pericentre distance (32 kpc). We also show that within a family of orbital parameters, the Giant Stream (GS) can be formed with various merger mass ratios, from 2:1 to 300:1. A recent major merger may be the only way to create the very unusual age–dispersion relation in the disc. It reproduces and explains the long-lived 10 kpc ring, the widespread and recent star formation event, the absence of a remnant of the GS progenitor, the apparent complexity of the 3D spatial distribution of the GS, the NE and G Clumps and their formation process, and the observed slope of the halo profile. These modelling successes lead us to propose that the bulk of the substructure in the M31 halo, as well as the complexity of the inner galaxy, may be attributable to a single major interaction with a galaxy that has now fully coalesced with Andromeda.
Activity of (2060) Chiron possibly caused by impacts?

Published: December 2017

Abstract
The centaur 95P/(2060) Chiron is showing comet-like activity since its discovery, but the mass-loss mechanisms triggering its activity remained unexplained. Although the collision rates in the centaur region are expected to be very low, and impacts are thought not to be responsible for the mass-loss, since the recent indications that Chiron might possess a ring similar to Chariklo's, and assuming that there is debris orbiting around, the impact triggered mass-loss mechanism should not be excluded as a possible cause of its activity. From time series observations collected on Calar Alto Observatory in Spain between 2014 and 2016, we found that the photometric scatter in Chiron's data is larger than a control star's scatter, indicating a possible microactivity, possibly caused by debris falling back to Chiron's surface and lifting small clouds of material. We also present rotational light curves, and measurements of Chiron's absolute magnitudes, which are consistent with the models supporting the presumption that Chiron possesses rings. By co-adding the images acquired in 2015, we have detected an ∼5 arcsec long tail, showing a surface brightness of 25.3 mag(V) arcsec−2.
Treatment of an Anterior Inferior Cerebellar Artery Aneurysm With Microsurgical Trapping and In Situ Posterior Inferior Cerebellar Artery to Anterior Inferior Cerebellar Artery Bypass: Case Report
Authors: Lee Bryan S , Witek Alex M , Moore Nina Z , Bain Mark D 
Published: December 2017

Abstract

BACKGROUND
Anterior inferior cerebellar artery (AICA) aneurysms are rare lesions whose treatment can involve microsurgical and/or endovascular techniques. Such treatment can be challenging and may carry a significant risk of neurological morbidity.

OBJECTIVE
To demonstrate a case involving a complex AICA aneurysm that was treated with a unique microsurgical approach involving trapping the aneurysm and performing in Situ bypass from the posterior inferior cerebellar artery (PICA) to the distal AICA. The nuances of AICA aneurysms and revascularization strategies are discussed.

METHODS
The aneurysm and the distal segments of AICA and PICA were exposed with a retrosigmoid and far lateral approach. A side-to-side anastomosis was performed between the adjacent caudal loops of PICA and AICA. The AICA aneurysm was then treated by trapping the aneurysm-bearing segment of the parent vessel between 2 clips.

RESULTS
A postoperative angiogram demonstrated a patent PICA-AICA bypass and complete occlusion of the AICA aneurysm. There were no complications, and the patient made an excellent recovery.

CONCLUSION
The combination of parent vessel sacrifice and bypass remains an excellent option for certain difficult-to-treat aneurysms. This case involving PICA-AICA bypass to treat an AICA aneurysm serves as an example of the neurosurgeon's ability to develop unique solutions that take advantage of individual anatomy.

Published: December 2017

Objectives:
To determine the clinical characteristics and outcomes of culture-negative septic shock in comparison with culture-positive septic shock.

Design:
Retrospective nested cohort study.

Setting:
ICUs of 28 academic and community hospitals in three countries between 1997 and 2010.

Subjects:
Patients with culture-negative septic shock and culture-positive septic shock derived from a trinational (n = 8,670) database of patients with septic shock.

Interventions:
None.

Measurements and Main Results:
Patients with culture-negative septic shock (n = 2,651; 30.6%) and culture-positive septic shock (n = 6,019; 69.4%) were identified. Culture-negative septic shock compared with culture-positive septic shock patients experienced similar ICU survival (58.3% vs 59.5%; p = 0.276) and overall hospital survival (47.3% vs 47.1%; p = 0.976). Severity of illness was similar between culture-negative septic shock and culture-positive septic shock groups ([mean and sd Acute Physiology and Chronic Health Evaluation II, 25.7 ± 8.3 vs 25.7 ± 8.1]; p = 0.723) as were serum lactate levels (3.0 [interquartile range, 1.7–6.1] vs 3.2 mmol/L [interquartile range, 1.8–5.9 mmol/L]; p = 0.366). As delays in the administration of appropriate antimicrobial therapy after the onset of hypotension increased, patients in both groups experienced congruent increases in overall hospital mortality: culture-negative septic shock (odds ratio, 1.56; 95% CI [1.47–1.66]; p < 0.0001) and culture-positive septic shock (odds ratio, 1.65; 95% CI [1.59–1.71]; p < 0.0001).

Conclusions:
Patients with culture-negative septic shock behave similarly to those with culture-positive septic shock in nearly all respects; early appropriate antimicrobial therapy appears to improve mortality. Early recognition and eradication of infection is the most obvious effective strategy to improve hospital survival.
Predictors of In-Hospital Mortality After Rapid Response Team Calls in a 274 Hospital Nationwide Sample*
Authors: Shappell Claire , Snyder Ashley , Edelson Dana P. , Churpek Matthew M. 
Published: December 2017

Objectives:
Despite wide adoption of rapid response teams across the United States, predictors of in-hospital mortality for patients receiving rapid response team calls are poorly characterized. Identification of patients at high risk of death during hospitalization could improve triage to intensive care units and prompt timely reevaluations of goals of care. We sought to identify predictors of in-hospital mortality in patients who are subjects of rapid response team calls and to develop and validate a predictive model for death after rapid response team call.

Design:
Analysis of data from the national Get with the Guidelines-Medical Emergency Team event registry.

Setting:
Two-hundred seventy four hospitals participating in Get with the Guidelines-Medical Emergency Team from June 2005 to February 2015.

Patients:
282,710 hospitalized adults on surgical or medical wards who were subjects of a rapid response team call.

Interventions:
None.

Measurements and Main Results:
The primary outcome was death during hospitalization; candidate predictors included patient demographic- and event-level characteristics. Patients who died after rapid response team were older (median age 72 vs 66 yr), were more likely to be admitted for noncardiac medical illness (70% vs 58%), and had greater median length of stay prior to rapid response team (81 vs 47 hr) (p < 0.001 for all comparisons). The prediction model had an area under the receiver operating characteristic curve of 0.78 (95% CI, 0.78–0.79), with systolic blood pressure, time since admission, and respiratory rate being the most important variables.

Conclusions:
Patients who die following rapid response team calls differ significantly from surviving peers. Recognition of these factors could improve postrapid response team triage decisions and prompt timely goals of care discussions.
Optimal Cerebral Perfusion Pressure in Centers With Different Treatment Protocols
Authors: Howells Tim , Smielewski Peter , Donnelly Joseph , Czosnyka Marek , Hutchinson Peter J. A. , Menon David K. , Enblad Per , Aries Marcel J. H. 
Published: December 2017

Objectives:
The three centers in this study have different policies regarding cerebral perfusion pressure targets and use of vasopressors in traumatic brain injury patients. The aim was to determine if the different policies affected the estimation of cerebral perfusion pressure which optimizes the strength of cerebral autoregulation, termed “optimal cerebral perfusion pressure.”

Design:
Retrospective analysis of prospectively collected data.

Setting:
Three neurocritical care units at university hospitals in Cambridge, United Kingdom, Groningen, the Netherlands, and Uppsala, Sweden.

Patients:
A total of 104 traumatic brain injury patients were included: 35 each from Cambridge and Groningen, and 34 from Uppsala.

Interventions:
None.

Measurements and Main Results:
In Groningen, the cerebral perfusion pressure target was greater than or equal to 50 and less than 70 mm Hg, in Uppsala greater than or equal to 60, and in Cambridge greater than or equal to 60 or preferably greater than or equal to 70. Despite protocol differences, median cerebral perfusion pressure for each center was above 70 mm Hg. Optimal cerebral perfusion pressure was calculated as previously published and implemented in the Intensive Care Monitoring+ software by the Cambridge group, now replicated in the Odin software in Uppsala. Periods with cerebral perfusion pressure above and below optimal cerebral perfusion pressure were analyzed, as were absolute difference between cerebral perfusion pressure and optimal cerebral perfusion pressure and percentage of monitoring time with a valid optimal cerebral perfusion pressure. Uppsala had the highest cerebral perfusion pressure/optimal cerebral perfusion pressure difference. Uppsala patients were older than the other centers, and age is positively correlated with cerebral perfusion pressure/optimal cerebral perfusion pressure difference. Optimal cerebral perfusion pressure was significantly lower in Groningen than in Cambridge. There were no significant differences in percentage of monitoring time with valid optimal cerebral perfusion pressure. Summary optimal cerebral perfusion pressure curves were generated for the combined patient data for each center. These summary curves could be generated for Groningen and Cambridge, but not Uppsala. The older age of the Uppsala patient cohort may explain the absence of a summary curve.

Conclusions:
Differences in optimal cerebral perfusion pressure calculation were found between centers due to demographics (age) and treatment (cerebral perfusion pressure targets). These factors should be considered in the design of trials to determine the efficacy of autoregulation-guided treatment.
