Galaxy evolution in groups
Authors: Mazzei P. , Marino A. , Rampazzo R. , Plana H. , Rosado M. , Arias L. 
Published: October 2017

Context. Local Group (LG) analogs (LGAs) are galaxy associations dominated by a few bright spirals reminiscent of the LG. The NGC 3447/NGC 3447A system is a member of the LGG 225 group, a nearby LGA. This system is considered a physical pair composed of an intermediate-luminosity late-type spiral, NGC 3447 itself, and an irregular companion, NGC 3447A, linked by a faint, short filament of matter. A ring-like structure in the NGC 3447 outskirts has been emphasised by Galaxy Evolution Explorer (GALEX) observations.
Aims. This work aims to contribute to the study of galaxy evolution in low-density environments, a favourable habitat to highly effective encounters, shedding light on the evolution of the NGC 3447/NGC 3447A system.
Methods. We performed a multi-λ analysis of the surface photometry of this system to derive its spectral energy distribution and structural properties using ultraviolet (UV), Swift UVOT, and optical Sloan Digital Sky Survey (SDSS) images complemented with available far-IR observations. We also characterised the velocity field of the pair using two-dimensional Hα kinematical observations of the system obtained with PUMA Fabry-Perot interferometer at the 2.1 m telescope of San Pedro Mártir (Mexico). All these data are used to constrain smooth particle hydrodynamic simulations with chemo-photometric implementation to shed light on the evolution of this system.
Results. The luminosity profiles, from UV to optical wavelengths, are all consistent with the presence of a disc extending and including NGC 3447A. The overall velocity field does not emphasise any significant rotation pattern, rather a small velocity gradient between NGC 3447 and NGC 3447A. Our simulation, detached from a large grid explored to best-fit the global properties of the system, suggests that this arises from an encounter between two halos of equal mass.
Conclusions. NGC 3447 and NGC 3447A belong to the same halo, NGC 3447A being a substructure of the same disk including NGC 3447. The halo gravitational instability, enhanced by the encounter, fuels a long-lived instability in this dark-matter-dominated disk, driving the observed morphology. The NGC 3447/NGC 3447A system may warn of a new class of “false pairs” and the potential danger of a misunderstanding of such objects in pair surveys that could produce a severe underestimate of the total mass of a system.
Lesbian Pregnancy: Care and Considerations
Authors: Bushe Sierra , Romero Iris 
Published: October 2017

AbstractThe constructs and the provision of preconception and obstetrical care have historically been based on the assumption of heterosexuality, and have often excluded lesbian women. However, due to significant strides in lesbian, gay, bisexual, transgender, and queer (LGBTQ) civil rights, more lesbian women desire to create and expand their families, and lesbian parented families are increasing. This places obstetrical care providers at the forefront of the movement to build inclusive health care environments. Therefore, it is incumbent upon those of us who work in obstetrics to understand, recognize, and respect the unique cultural considerations that pertain to lesbian women and couples seeking parenthood. This review seeks to provide culturally sensitive guidance on the specific concerns and challenges lesbians face, from preconception care to postpartum care, and briefly addresses legal issues and considerations for the nonbiologic mother. The recommendations outlined here are drawn from studies of the experiences of lesbian women with pregnancy. However, the scientific literature is very limited, and there is a clear need for additional obstetrical research focused on this patient group. As professionals committed to assuring optimal outcomes for all obstetrical patients, it is crucial that we promote the inclusion of sexual minority women in our clinical practices and research endeavors.
Vocal Symptoms and Associated Risk Factors between Male and Female University Teachers
Authors: Korn Gustavo , Park Sung , Pontes Antonio , Pontes Paulo 
Published: October 2017

Introduction Many recent studies on teachers warn of the adverse effects that voice problems have on work performance. However, only a few of these studies included university teachers.
Objective To compare the vocal symptoms and risk factors between male and female university teachers in a private institution within the city of São Paulo.
Methods In a cross-sectional survey, a voice self-evaluation form prepared by the Ministry of Labor in Brazil was administered to 846 university teachers at a private institution in the city of São Paulo.
Results The percentage of hoarseness, vocal tract discomfort, neck pain and foreign body sensation was significantly higher in female than in male subjects. A significantly higher percentage of males participated in other professional activities in addition to teaching, reported working in a calm environment compared with working in a moderately or severely tense and stressful environment, and rated themselves as calm, slightly stressed and anxious or moderately stressed and anxious rather than very stressed and anxious. A significantly higher percentage of females spent most of their time teaching compared with performing other professional activities, and rated themselves as chatty or impulsive.
Conclusion Among university teachers, a significantly higher percentage of females than males reported hoarseness, vocal tract discomfort, neck pain and foreign body sensation. Some risk factors related to work organization, workplace environment, voice care and quality of life variables were related to this higher prevalence in females.
Preparing Future Health Professionals for Interprofessional Collaborative Practice Part 2: The Student Experience
Authors: Inzana Rebecca , Cahn Peter , Reidy Patricia , Knab Mary 
Published: October 2017

AbstractResponding to increasing calls for change in systems of care delivery and revisions in the way health professionals are educated, academic programs across the health professions, including speech-language pathology, are placing increased emphasis on interprofessional collaborative practice and interprofessional education. This article provides a foundation for understanding these changes and what is driving them. Using an example from one academic program, it provides a view of the shifting student experience and discusses implications for speech-language pathologists serving as educators and supervisors in external placements. The article concludes with suggestions for integrating competencies for collaborative practice into one's clinical teaching and maximizing effectiveness in fostering student readiness for practice in the complex medical and education environments in which speech-language pathologists practice.
The Natural Growth Rate of Residual Juvenile Angiofibroma
Authors: Rowan Nicholas , Stapleton Amanda , Heft-Neal Molly , Gardner Paul , Snyderman Carl 
Published: October 2017

Objectives Examine the postoperative growth rate of residual juvenile angiofibroma (JA) in a large series of patients relative to pediatric growth parameters and other prognostic factors. Establish an algorithm for postoperative surveillance of patients with JA.
Design Retrospective case series.
Setting Tertiary referral academic center.
Participants Pediatric patients undergoing surgical resection of JA between September 2005 and June 2015.
Main Outcome Measures Postoperative recurrence and tumor growth rates.
Results Thirty-eight patients were identified with a mean follow-up of 24.1 months. Sixty-eight percent (26/34) of patients achieved gross total resection, and 32% (12/38) had persistent postoperative disease. Of those with postoperative residual tumor, all had preoperative skull base involvement and residual blood supply from the internal carotid artery following embolization. Sixty-seven percent (8/12) of patients with postoperative residual tumor demonstrated radiographic stability of disease with scans being completed approximately every 6 months. Radiographic rates of disease progression ranged from 4.1 to 9.22 mm/year.
Conclusions Patients with preoperative skull base involvement and residual vascularity following preoperative embolization are more likely to have residual postoperative disease, and a longer postoperative follow-up is warranted in these patients. Progression of residual disease occurred approximately 7.5 months postoperatively. Younger patients may be more likely to need further intervention for postoperative residual disease, and postoperative imaging at 6-month intervals appears appropriate.
Open vs. Percutaneous Pedicle Screw Insertion for Thoracolumbar Traumatic A3 and A4 AO Fractures - 18-Months Follow-Up
Authors: Romero Flávio , Vieira Rodolfo , Ancheschi Bruno 
Published: October 2017

Purpose To compare the efficacy and safety of the percutaneous screw fixation (PSF) and the open pedicle screw fixation (OPSF) on thoracolumbar (TL) fracture.
Methods Sixty-four adult patients with TL vertebral fractures who underwent open or percutaneous posterior short-segment transpedicular screw fixation between January of 2013 and September of 2015 were retrospectively reviewed. All patients underwent clinical, radiological and quality of life follow-up for at least 18 months.
Results There was no significant difference in age, gender, time between injury and surgery, and preoperative percentage of anterior column height, preoperative sagittal regional Cobb angle, or kyphotic angle of fractured vertebra between these two groups (p > 0.05). There was significantly less intraoperative blood loss in the PSF (87.6 ± 24.6 mL) than in the OPSF group (271.4 ± 142.6 mL) (p < 0.05). The mean surgery time was 62 minutes (range 42–130 minutes) for open and 58 minutes (range 35 to 128 minutes) for percutaneous screw fixation. The surgery time was shorter in the PSF group, but with no statistical significance (p > 0.05). The mean Oswestry disability index (ODI) scores after 18-months were 23.12 ± 8.2 for the PSF and 24.12 ± 9.2 for the OPSF group, without any statistical significance (p > 0.05).
Conclusion Both open and percutaneous screw fixations are safe and effective. The percutaneous techniques significantly reduced the intraoperative blood loss compared with the open techniques.
Nebenwirkungen von Psychopharmaka: Tipps für die Praxis

Published: October 2017

AbstractPsychotropics are highly effective medications that, however, have adverse drug reactions attached to them. They are indispensable for many patients. How to cope with side effects – watchful waiting, dose reduction, change of medication, addition of an “antidote” and behavioural modifications – depends on their nature, severity and finally the patients wish. This review is meant to aid clinician’s and patient’s decisions in case of the occurrence of compromising, frequent adverse drug reactions.
Fallpauschalenabbildung plastischer Rekonstruktionen bei malignen Hauttumoren im Kopf-Hals-Bereich
Authors: Lotter Oliver , Micheel Manuela , Jaminet Patrick 
Published: October 2017

Zusammenfassung
Hintergrund In Deutschland wurden vor nunmehr 13 Jahren Fallpauschalen als medizinisch-ökonomisches Klassifikationssystem eingeführt.
Im Folgenden soll die Abbildung plastischer Rekonstruktionen bei malignen Hauttumoren im Kopf-Hals-Bereich durch Diagnosis Related Groups
(DRG) analysiert werden.
Material und Methoden Vier verschiedene Hauptdiagnosen (Malignes Melanom, Basalzellkarzinom, Plattenepithelkarzinom, Carcinoma in
situ) an bis zu 6 unterschiedlichen Lokalisationen im Kopf-Hals-Bereich wurden mit folgenden Prozeduren kombiniert und mittels DRG-Grouper
untersucht: Exzision mit Primärnaht, Exzision mit temporärer Weichteildeckung, Plastische Deckung durch Eigenhaut, lokale, freie, gestielte
regionale Lappen und Fernlappenplastiken sowie Kombinationsdeckungen.
Ergebnisse Durch 5750 verschlüsselte Diagnose-Prozeduren-Kombinationen wurden 10 unterschiedliche DRGs bestimmt. Bei großflächigen
temporären Weichteildeckungen und Hauttransplantationen dominiert die DRG J22Z (Erlös 2817 €). In 2017 wurden die häufig durchgeführten
lokalen Lappenplastiken hiervon abgewertet und führen aktuell in die DRG J11D (Erlös 1903 €). In diesem Zusammenhang sind
Fallzusammenführungen durch ein zweizeitiges stationäres Vorgehen (Sitzung 1: Exzision, Sitzung 2: Plastische Deckung) von besonderer
Bedeutung. Malignome an der Lippe ergeben eine eher unruhige DRG-Abbildung ohne klar abzuleitende Gruppierungsregeln. Die hochbewertete
Basis-DRG J08 (DRGs J08A, J08B und J08C) kann nahezu ausnahmslos durch einzelne zusätzliche OPS-Ziffern erreicht werden.
Schlussfolgerung Die derzeitige Fallpauschalensituation für plastische Rekonstruktionen im Rahmen maligner Hauttumoren bietet etliche
potentielle Fehlanreize, welche Einfluss auf die Patientenversorgung haben können. Auf der Suche nach einem diversifizierten DRG-Portfolio
bietet sich die Basis-DRG J08 neben der gängigen Kodierpraxis mit entsprechenden Fallpauschalen an. Die Autoren sehen darin die Möglichkeit,
bei aktueller Abwertung auch ressourcenintensive Spezialfälle aufwandgerecht abzubilden. Vor einer unbegründeten und inflationären Anwendung
wird jedoch aufgrund einer fehlenden nachhaltigen Ausrichtung aufgrund von Verwässerung ausdrücklich gewarnt.
Magnifying image-enhanced endoscopy for collagenous colitis
Authors: Kobayashi Masaaki , Hoshi Takahiro , Morita Shin-ich , Kanefuji Tsutomu , Suda Takeshi , Hasegawa Go , Terai Shuji 
Published: October 2017

Abstract
Background and study aims We report a case series of 5 patients with collagenous colitis (CC) presenting with chronic watery diarrhea, who were subjected to magnifying, chromoendoscopy and narrow band imaging (NBI). Magnifying chromoendoscopy revealed whitish-clouded, honeycomb-like appearance at orifices of the crypts. NBI with high magnification revealed irregular caliber variation of the subepithelial capillary network. Presence of these features corresponded with histological characteristics of CC indicated by thickening of the subepithelial collagen layer. We concluded that magnifying image-enhanced endoscopy is a reliable tool to diagnose CC.
„Surgeon-modified“ Stentgrafts für den Notfall – Ergänzung zu „off-the-shelf“ Prothesen für die Versorgung von komplexen abdominellen und thorakoabdominellen Aortenpathologien

Published: October 2017

Zusammenfassung
Hintergrund Die endovaskulären Techniken haben die Therapie von Erkrankungen der abdominellen und thorakoabdominellen Aorta revolutioniert. Für die Versorgung im Bereich der infrarenalen Aorta ist die endovaskuläre Therapie mittlerweile ein Standardverfahren für Elektivfälle und im Notfall. Für komplexe, d. h. die renoviszeralen Gefäße einbeziehende, abdominelle und thorakoabdominelle Aortenpathologien bestehen sowohl offen als auch endovaskulär große technische Herausforderungen. Aufgrund der hohen Mortalität und Morbidität der offenen Chirurgie, insbesondere im Notfall, haben sich auch hier verschiedene endovaskuläre Techniken, insbesondere für Mittel- bis Hochrisikopatienten, zur Versorgung entwickelt.
Ergebnisse Zu den endovaskulären Therapieoptionen zählen grundsätzlich die fenestrierten und gebranchten Stentprothesen, die entsprechend der Anatomie runde Aussparungen („Fenestrierung“) oder Abzweigungen („Branches“) für die renoviszeralen Gefäße haben, sowie die Chimney-Graft-Technik. Im Elektivfall können patientenindividuelle fenestrierte und gebranchte Prothesen („custom-made“) bestellt werden. Planung, Produktion und Lieferung erfordern jedoch eine Wartezeit von bis zu 12 Wochen. Im dringlichen Fall steht aktuell nur eine 4-fach gebranchte und patientenunspezifische, d. h. „off-the-shelf“ („von der Stange“) Stentprothese zur Verfügung, die für nur schätzungsweise 60% der Patientenanatomien mit komplexem abdominellem und thorakoabdominellem Aortenaneurysma passt. Für Patienten ohne passende Anatomie stehen die sog. „surgeon-modified“ oder „vom Chirurgen modifizierten“ Stentprothesen als Alternative zur Verfügung. Hierbei wird eine kommerzielle Prothese direkt präoperativ mit den notwendigen Fenestrierungen modifiziert. Verglichen mit den „off-the-shelf“ Stentprothesen weist die Literatur aktuell für die „surgeon-modified“ Technik ähnliche Ergebnisse bez. Morbidität und Mortalität auf.
Schlussfolgerung Die „surgeon-modified“ Stentprothesen haben ihren Stellenwert bei Hochrisikopatienten mit symptomatischen und gedeckt rupturierten komplexen Aneurysmen. Bis kommerzielle fenestrierte und gebranchte Stentprothesen für alle anatomischen Gegebenheiten als „off-the-shelf“ Prothesen vorhanden sind, stellt die „surgeon-modified“ Technik eine gute Behandlungsoption dar.
Supply and demand drive a critical transition to dysfunctional fisheries

Published: October 2017

Significance
Recent years have witnessed strenuous ongoing debate about the sustainability of many commercial fisheries. Here we apply commonly accepted principles of fishery science to consider the impact of price flexibility on long-term fishery sustainability in an era of increasing demand due to population increase and rising economic expectations. We apply this model to two commercial oceanic fisheries (cod and pollock) to demonstrate that harvest and price statistics that are commonly available for commercial fisheries can be used to diagnose the degree to which a given fishery has been overharvested. More importantly, the same heuristic can also be used to identify plausible targets for fishery rehabilitation and evaluate the effectiveness of alternative policy options to achieve those goals.
Rise and fall of elites: professionals as movers?
Authors: Gulbrandsen Trygve 
Published: October 2017

ABSTRACT
A significant topic within elite research deserving more attention is the issue of the “rise and fall of elites”. This subject addresses changes in the composition of elites, the emergence of new elites and the decline of established ones, and covers questions like: In what ways do particular groups climb to elite power and status? What may explain the rise of new elite groups? In this paper, the focus is upon the role of professionals in the processes of elite ascent (and descent). Most holders of elite positions are professionals. This fact invites to draw on approaches within the professions literature to explain the rise of elites. This paper presents three empirical cases of elite ascent in Norway – the rise of economists, communication practitioners and public accountants. The three historical cases demonstrate that the professionals themselves actively sought to promote their expertise, and to expand their occupational territory. Nonetheless, the professionals’ own efforts to obtain collective advancement contributed to a lesser degree to their elite ascent than more fundamental economic and political changes in the Norwegian society.
3D-MICE: integration of cross-sectional and longitudinal imputation for multi-analyte longitudinal clinical data
Authors: Luo Yuan , Szolovits Peter , Dighe Anand S , Baron Jason M 
Published: October 2017

AbstractObjectiveA key challenge in clinical data mining is that most clinical datasets contain missing data. Since many commonly used machine learning algorithms require complete datasets (no missing data), clinical analytic approaches often entail an imputation procedure to “fill in” missing data. However, although most clinical datasets contain a temporal component, most commonly used imputation methods do not adequately accommodate longitudinal time-based data. We sought to develop a new imputation algorithm, 3-dimensional multiple imputation with chained equations (3D-MICE), that can perform accurate imputation of missing clinical time series data.MethodsWe extracted clinical laboratory test results for 13 commonly measured analytes (clinical laboratory tests). We imputed missing test results for the 13 analytes using 3 imputation methods: multiple imputation with chained equations (MICE), Gaussian process (GP), and 3D-MICE. 3D-MICE utilizes both MICE and GP imputation to integrate cross-sectional and longitudinal information. To evaluate imputation method performance, we randomly masked selected test results and imputed these masked results alongside results missing from our original data. We compared predicted results to measured results for masked data points.Results3D-MICE performed significantly better than MICE and GP-based imputation in a composite of all 13 analytes, predicting missing results with a normalized root-mean-square error of 0.342, compared to 0.373 for MICE alone and 0.358 for GP alone.Conclusions3D-MICE offers a novel and practical approach to imputing clinical laboratory time series data. 3D-MICE may provide an additional tool for use as a foundation in clinical predictive analytics and intelligent clinical decision support.
Impact of Timing of Adjuvant Chemoradiation for Glioblastoma in a Large Hospital Database
Authors: Osborn Virginia W , Lee Anna , Garay Elizabeth , Safdieh Joseph , Schreiber David 
Published: October 2017

Abstract

BACKGROUND
Although the standard of care for glioblastoma remains maximal safe resection followed by chemoradiation, conflicting reports have emerged regarding the importance of the time interval between these 2 treatments.

OBJECTIVE
To assess whether differences in the duration between surgery and initiation of chemoradiation for glioblastoma had an impact on overall survival (OS) in a large hospital-based database.

METHODS
The National Cancer Database was queried to identify patients diagnosed with glioblastoma between 2010 and 2012 treated with surgery followed by chemoradiation. Patients who received biopsy only were excluded. The time from surgery to initiation of radiation therapy was divided into 4 equal quartiles of ≤24, 25 to 30, 31 to 37, and >37 d. Patient characteristics were compared between groups using Pearson Chi Square and Fisher's Exact test. OS was analyzed via the Kaplan–Meier method and compared via the log-rank test. Univariable and multivariable Cox regression were performed to assess for impact of covariables on OS.

RESULTS
A total of 11 652 patients were included in the analysis. Median duration from surgery to radiation was 30 d. On multivariable regression, black race, larger tumor, gross-total resection, methyguanine-methyl transferase (MGMT+), and treatment at an academic facility were associated with a duration >30 d. On multivariable analysis, there were no significant differences when comparing start within 24 d to 25 to 30 d (hazard ratio [HR] 0.96, 95% confidence interval [CI] 0.90-1.01, P = .13) or > 37 d (HR 0.97, 95% CI 0.91-1.03, P = .26), although a small OS improvement was seen if initiated within 31 to 37 d (HR 0.93, 95% CI 0.88-0.99, P = .02).

CONCLUSION
There was no clear association between duration from surgery to initiation of chemoradiation on OS.
