Applications of a robotic stereotactic arm for pediatric epilepsy and neurooncology surgery
Authors: Miller Brandon A. , Salehi Afshin , Limbrick David D. , Smyth Matthew D. 
Published: August 2017

OBJECTIVEThe ROSA device is a robotic stereotactic arm that uses a laser system to register the patient’s head or spine with MR or CT images. In this study, the authors analyze their experience with this system in pediatric neurosurgical applications and present selected cases that exemplify the usefulness of this system.METHODSThe authors reviewed all cases that utilized the ROSA system at their institution. Patient demographics, pathology, complications, electrode placement, laser ablation, and biopsy accuracy were analyzed. Patient disposition and condition at follow-up were also analyzed.RESULTSSeventeen patients underwent 23 procedures using the ROSA system. A total of 87 electroencephalography electrodes were placed, with 13% deviating more than 3 mm from target. Six patients underwent stereotactic needle biopsy, and 9 underwent laser interstitial thermotherapy (LITT). One patient who underwent LITT required a subsequent craniotomy for tumor resection. Another patient experienced an asymptomatic extraaxial hematoma that spontaneously resolved. No patient suffered neurological complications during follow-up. Follow-up from the last procedure averaged 180 days in epilepsy patients and 309 days in oncology patients.CONCLUSIONSThe precision, ease of use, and versatility of the ROSA system make it well suited for pediatric neurosurgical practice. Further work, including long-term analysis of results and cost-effectiveness, will help determine the utility of this system and if its applications can be expanded.
Aux origines du « taylorisme » à la française : Gustave Ply

Published: August 2017

En 1888, le capitaine d’artillerie Gustave Ply publie son « étude sur l’organisation des services techniques dans les manufactures d’armes ». Au-delà du modèle technique proposé, cette étude souligne le rôle joué dans la rationalisation de l’organisation industrielle par l’industrie militaire d’Etat. Elle dévoile également les racines historiques d’un « taylorisme » à la française qui. au moment où il voit le jour, ignore encore ce nom et dont l’impact sur le développement de l’industrie française peut être discuté.
Acoustic reflex measurements and the loudness function in sensorineural hearing loss
Authors: Uliel Sheila 
Published: August 2017

The suprathreshold acoustic reflex responses of forty two ears affected by sensorineural hearing loss of cochlear origin and fifty-eight ears demonstrating normal hearing, were recorded by means of an electro-acoustic impedance meter and attached X-Y recorder. The recordings were done in ascending and descending fashion, at successively increasing and decreasing 5dB intensity levels from 90-120-90 dB HL respectively, for the individual pure-tone frequencies of 500, 1 000, 2 000 and 4 000 Hz. The contralateral mode of measurement was employed. Analysis of these recordings indicated that the acoustic reflex responses could be differentiated into five characteristic patterns of growth, which could be depicted upon a continuum of peaked, peaked-rounded, rounded, rounded-flat, and flat shapes. The peaked and peaked-rounded patterns were found to predominate at all four pure-tone frequencies in the normal ears, while the rounded-fiat and flat patterns were found to predominate only at the higher pure-tone frequencies of 2 000 and 4 000 Hz in the ears affected by sensorineural hearing loss. This latter relationship was also able to be applied to two disorders of the loudness functio— loudness recruitment and hyperacusis. It was concluded that the flattened acoustic reflex patterns at the higher pure-tone frequencies constituted a potential diagnostic cue related to the differential diagnosis of sensorineural hearing loss, and to disorders of the loudness function.
Post-laryngectomy therapy: A communication approach
Authors: Alant Erna 
Published: August 2017

This article deals with the interpretation of post-laryngectomy therapy within the framework of communication. The communication approach towards rehabilitation emphasizes the necessity of incorporating verbal communication and non-verbal communication into the diagnostic and therapy procedures because of the close link between the two modes of communication. Diagnosis and therapy are discussed in terms of communication skills, social and personal sensitivity and tension. Throughout the article, the stress is on the therapist's creative role in the laryngectomy patient's construction of reality.

Published: August 2017

Abstract. In this study we aim to assess the WRF-Chem model capacity to reproduce dust transport over the eastern Mediterranean. For this reason, we compare the model aerosol optical depth (AOD) outputs to observations, focusing on three key regions: North Africa, the Arabian Peninsula and the eastern Mediterranean. Three sets of four simulations have been performed for the 6-month period of spring and summer 2011. Each simulation set uses a different dust emission parametrisation and for each parametrisation, the dust emissions are multiplied with various coefficients in order to tune the model performance. Our assessment approach is performed across different spatial and temporal scales using AOD observations from satellites and ground-based stations, as well as from airborne measurements of aerosol extinction coefficients over the Sahara. Assessment over the entire domain and simulation period shows that the model presents temporal and spatial variability similar to observed AODs, regardless of the applied dust emission parametrisation. On the other hand, when focusing on specific regions, the model skill varies significantly. Tuning the model performance by applying a coefficient to dust emissions may reduce the model AOD bias over a region, but may increase it in other regions. In particular, the model was shown to realistically reproduce the major dust transport events over the eastern Mediterranean, but failed to capture the regional background AOD. Further comparison of the model simulations to airborne measurements of vertical profiles of extinction coefficients over North Africa suggests that the model realistically reproduces the total atmospheric column AOD. Finally, we discuss the model results in two sensitivity tests, where we included finer dust particles (less than 1 µm) and changed accordingly the dust bins' mass fraction.
ROSENZWEIG, SCHELLING ET L’HISTOIRE: QUELQUES APERÇUS
Authors: Bensussan Gérard 
Published: August 2017

Le rapport Rosenzweig / Schelling est le plus souvent, et à bon droit, étudié à partir de l’influence des Âges du monde sur l’écriture de l’Etoile de la rédemption. Le présent texte suggère une autre voie, non exclusive de la première, constituée autour de la dette rosenzweigienne contractée à l’endroit de la pensée schellingienne de l’historicité. Cette étude retrace les contenus et les attendus de cette dette sous quatre registres : 1. L’histoire, chez Schelling, est soumise à sa disposition comme articulation de temporalités sédimentées et coexistantes ; 2. Une véritable pensée de l’histoire peut être ainsi déterminée, très différente d’une « philosophie de l’histoire » : elle accueille l’histoire comme ce par quoi se fait connaître à l’expérience un imprépensable ; 3. Cette histoire « expériencielle » se surprend sans cesse en effectuant l’événement de ce qui ne cesse d’advenir dans sa Wirklichkeit ; 4. L’acte fondatif et inaugural de l’histoire est un mouvement que les hommes ne peuvent reconnaître comme quelque chose qu’ils auraient accompli. L’histoire avance, mais sans voir. Elle s’avance sans se voir selon un « progrès anti-historique ». Le parcours de Rosenzweig refait à sa façon ce chemin. Il va d’une conception néo-hégélienne de l’histoire universelle à l’idée d’une histoire discontinue, et même d’une méta- ou d’une extrahistoricité, c’est-à-dire d’une d’extériorité à l’histoire sans laquelle celle-ci s’aplatirait dans sa pure immanence et ne se laisserait pas penser dans sa concrétude opaque et chaotique.
Procalcitonin Level as a Surrogate for Catheter-Related Blood Stream Infection among Hemodialysis Patients
Authors: Hamada Imam Mahmoud , Gamal Eman 
Published: August 2017

Introduction Catheter-related bloodstream infection (CRBSI) is a frequent complication among hemodialysis patients who usually are presented with nonspecific signs such as fever, rigors, and hypotension. Blood culture will take up to 5 days and antimicrobials will be started. Procalcitonin (PCT) is a valid marker in sepsis. Our goal in this study is to evaluate its usefulness as a diagnostic marker in detecting CRBSI among hemodialysis patients who present with suspected CRBSI. Patients and methods Thirty-one hemodialysis patients with suspected CRBSI were enrolled in this study. PCT level was measured at the time of presentation. Patients were divided into two groups according to blood culture results: positive and negative groups. PCT level and other markers for inflammation: white blood cell count (WBC), C-reactive protein (CRP), and ferritin were compared between the two groups. Statistical analysis of variables was performed using the t-test or Mann-Whitney test together with Spearman correlation test. Results Thirty-one patients had median age 44.7 ± 2.1 years. They comprised 16 males (52%) and 15 females (48%). Sixteen patients had a positive blood culture result while in 15 it was negative. PCT level was significantly higher in the positive blood culture group (40.0 ± -21.9) (95% confidence interval [CI] 28.4-51.8) while its level was 1.1 ± 1 (95% CI 0.54-1.8) in the negative blood culture group [t(15) = -7, p<0.001). In the positive culture group, there was a correlation between CRP and ferritin (r = -0.58, p = 0.01, n = 16), while no correlation between PCT and other markers of inflammation. Conclusions PCT is a useful marker for diagnosis of CRBSI among hemodialysis patients.
Bursting Pressure of Triple-Lumen Central Venous Catheters under Static and Dynamic Loads
Authors: Beckingham Tim , Roberts Andy , St. John Alana , O'Callaghan Gerry 
Published: August 2017

Introduction Central venous catheter (CVC) access is commonplace in intensive care units. Patients undergoing computed tomographic angiography require injection of contrast at high flow rates (4.5 mL/s), often CVC access is not used due to safety concerns. The CVC might rupture at high flow rates, resulting in CVC fragmentation and embolization or contrast extravasation. The objective of this study is to determine the pressure required to burst a CVC under static load and compare this to the pressure generated by injection of contrast at high flow rates (dynamic load) through the distal (16-g) lumen of a triple-lumen CVC. Methods We gathered 16-cm long triple-lumen CVCs (n = 14) from patients with an average dwell time of 5.2 days (±2.7 days). Half the CVCs (n = 7) were subjected to static testing, where the distal lumen was occluded with the guidewire and super glue at the distal end of the catheter. The CVC was then placed into a 10-cm deep water bath at 37°C to simulate in vivo conditions and water was injected until catheter rupture. Dynamic pressure testing was done with the remaining catheters, with radio-contrast injected through the unoccluded distal lumen at flow rates of 4.5 mL/s, then 7 mL/s. Pressures were recorded throughout injection. Results During static testing, 6/7 CVCs burst at the distal lumen where the glue was applied, the remaining CVC burst proximal to the hub. PSI at burst during static testing was 184.2 PSI (95% confidence interval [CI] 174.3-194.1 PSI). During dynamic testing the mean peak pressures at 7 mL/s was 81.1 PSI (95% CI 73-89.2 PSI). At 4.5 mL/s the mean peak pressure was 47.9 PSI (95% CI 42.9-52.9 PSI). Conclusions No CVCs failed under dynamic loading with injection of contrast at flow rates (4.5 and 7 mL/s) high enough to support computed tomographic angiography. This suggests 16-cm triple-lumen CVCs can be used safely.

Published: August 2017

Introduction Children requiring long-term hemodialysis often face significant challenges due to their young age and small-vessel caliber for arteriovenous (AV) access creation. In this study, we report our experience of staged basilic vein transposition (BVT) in pediatric patients. Methods All patients undergoing staged BVT at a tertiary care pediatric hospital from 2003 to 2015 were reviewed. Indications for staged BVT included inadequate cephalic conduit or failed AV fistula using cephalic vein. Pertinent clinical variables were analyzed to determine treatment outcomes. Results Forty-two children (24 males, 57%) underwent 46 staged BVT during the study period. Median age was 12.8 ± 4.8 years (range 3-18). The mean weight was 47 ± 5.1 kg (range, 13-126 kg), with four children (10%) weighing ≤20 kg. Mean operative times for initial brachiobasilic AV fistula and staged BVT were 39 ± 12 minutes and 66 ± 17 minutes, respectively. Mean follow-up period was 5.4 ± 1.8 years. Functional maturation was achieved in 93% of BVTs. Early fistula thrombosis within 30 days following BVT occurred in four patients (10%). Late BVT thrombosis occurred in 13 patients (31%). Primary patency rates at 2 years and 4 years were 78% and 72%, respectively. Secondary patency rates at 2 years and 4 years were 86% and 82%, respectively. Conclusions Staged BVT is a durable and reliable autologous hemodialysis access in children who do not have adequate cephalic venous conduit.

Order Crossover Research: A 60‐Year Retrospective to Highlight Future Research Opportunities
Authors: Saldanha John Patrick , Swan Peter 
Published: August 2017

AbstractWe review the literature spanning 60 years of efforts to model the phenomenon of order crossover. The importance of this research has increased due to today's longer ocean supply chains, with their greater inherent uncertainty. The incidence of order crossover is higher in these supply chains, and ignoring it will result in overestimation of safety stock. The literature is grouped into four areas, which are described separately, and is mapped to reveal gaps. Gaps exist for combinations of lead time distributions, demand distributions, and inventory policies where extant methods do not address order crossover. The effective lead time approach has proven flexible enough to be used in a wide range of periodic review situations. However, our results show that its accuracy is undermined by bimodal skewed lead‐time distributions, especially when lower bounds are nonzero. Future research needs to concentrate on exploring nonparametric methods or similar methods robust to different lead time distribution assumptions to provide a method of setting safety stock in “real world” situations where orders cross.
Applying Theories from Other Disciplines to Logistics and Supply Chain Management: A Systematic Literature Review
Authors: Swanson David , Goel Lakshmi , Francisco Kristoffer , Stock James 
Published: August 2017

AbstractThis systematic literature review focuses on theory‐driven research in logistics and supply chain management (LSCM), giving particular attention to the originating disciplines of theories used. It is important to understand the origin of theory and how it has evolved within the LSCM discipline, because learning the past helps scholars understand the present and presage the future. To fulfill that objective, this research catalogs theories that have been used and also begins to identify how, when, and why borrowed theories have been adapted for LSCM research. The major results include theoretical insights such as trends in theory utilization and the methods and topics where theories are typically used or underused. The top five theories that have been used in LSCM research actually represent five different disciplines—management, economics, mathematics, psychology, and sociology—supporting the multidisciplinary nature of LSCM. To summarize this research, a forward‐looking perspective is taken to identify potential areas for the application of theory for future LSCM research. Comments are also provided on how researchers are employing more theory in the latest period of LSCM development (2011–2015).
Perspective and the future-in-the-past
Authors: Eckardt Regine 
Published: August 2017

The paper investigates the future-in-the-past (FiP) as in Peter would (later) see the Fujiyama. FiP can convey an outlook on events that, as the speaker knows, took place later (“objective sense”). FiP can also convey a past utterance or thought of a protagonist. In this perspective-taking sense, FiP sentences share the uncertainty about the future of present tense will-sentences. Kaufmann’s (2005) semantic treatment of the future is extended to account for shifted senses of the future-in-the-past, leading to the insight that tense scopes differently in non-shifted and shifted future-in-the-past. A final outlook speculates about more radical changes in the analysis of tense and aspect in order to account for this observation. This article is part of the special collection: Perspective Taking
Constraints in contact: Animacy in English and Afrikaans genitive variation – a cross-linguistic perspective
Authors: Rosenbach Anette 
Published: August 2017

This paper builds on the observation that the animacy effects we find in English genitive variation are part of a larger cross-linguistic pattern as reflected in possession splits based on animacy (Koptjevskaja-Tamm 2001, 2002; Stolz et al. 2008), which are an expression of harmonic alignment in the domain of possession (Aissen &amp; Bresnan 2002; Rosenbach 2008). Focussing on English and Afrikaans, a contrastive corpus analysis of genitive variation reveals similar forms of animacy splits in these two languages, though they differ in the strength of the animacy constraint, with the Afrikaans prenominal possessive (the se-genitive) occurring more freely with inanimate possessors than the English s-genitive. In a follow-up experimental study it is then shown that the weaker animacy constraint in Afrikaans carries over to the L2 English of Afrikaans speakers in South Africa. This study emphasizes the importance of a cross-linguistic perspective when looking at genitive variation in English and its varieties (1) to recognize that Englishes form part of a typological continuum of possession splits, and (2) to enable us to identify the possible transfer of constraint strengths from one language to another one in a situation where these languages are in contact, as in the case of English and Afrikaans in South Africa.This article is part of the Special Collection: Probabilistic grammars: Syntactic variation in a comparative perspective
An Analysis of Factors Associated with 25-Hydroxyvitamin D Levels in White and Non-White Canadians
Authors: Brooks Stephen P J , Greene-Finestone Linda , Whiting Susan , Fioletov Vitali E , Laffey Patrick , Petronella Nicholas 
Published: August 2017

Abstract
Vitamin D status was assessed in 19–79 year old whites (8351 participants of European ancestry) and non-whites (1840 participants encompassing allother ancestries) from cycles 1 to 3 (years 2007–2013) of the Canadian Health Measures Survey. Status was assessed using the U.S. Institute of Medicine (IOM) 25-hydroxyvitamin D [25(OH)D] cut point values of 30 and 40 nmol/L. Overall, median 25(OH)D concentrations were significantly higher in whites [58.9 (28.6, 100.1) nmol/L; 5th and 95th percentile] compared with non-whites [43.5 (19.0, 83.2); P &lt; 0.001]. Values were higher in females [58.5 (27.5, 101.3) nmol/L] when compared with males[53.5 (24.2, 92.7) nmol/L] and increased with age. Non-whites were more likely to have 25(OH)D values below IOM established cut points for optimum bone health with 20.1 (16.0, 24.2) and 42.2% (36.8, 47.7) of non-whites having serum 25(OH)D concentrations &lt;30 and &lt;40 nmol/L, respectively. The correspondingvalues for whites were 5.9 (4.6, 7.2) and 16.1% (14.0, 18.3). Values were lower during the first quarterwhen compared with the third quarter. Supplement intake was an important factor in determining 25(OH)D levels, but it did not alone account for the difference in status. Equivalent increases in 25(OH)D levelswere observed in whites and non-whites during the summer months, suggesting there was no functional difference in sun exposure response. It is apparent thata complex interaction of factors affect 25(OH)D values in free-living Canadians.
