ABSTRACTObjectiveThe aim of this prospective case–control study was to compare the long‐term effects of a residential cognitive‐behavioral treatment (CBT) for weight loss in severely obese patients with and without binge‐eating disorder (BED).MethodsWe assessed weight‐loss outcomes and psychological impairment in 54 severely obese female patients with BED and 54 patients matched by age, gender, and body mass index (BMI) without BED admitted to a residential CBT program. Body weight was measured at baseline and at 6‐month follow‐up and was reported by patients in a telephone interview at 5‐year follow‐up. Depression, eating disorder psychopathology, general psychopathology, and quality of life were assessed using validated instruments at baseline and at 6‐month follow‐up.ResultsObese patients with and without BED had similar weight loss at 6‐month and 5‐year follow‐ups. Although both groups showed improved psychosocial variables, at 6 months the BED group maintained higher psychological impairment. Nevertheless, at 5‐year follow‐up more than half of the BED participants were no longer classifiable as having BED.DiscussionThe presence of BED does not affect weight‐loss outcome in obese patients treated with the residential CBT for weight loss program considered. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:723–730)
Classifying eating disorders based on “healthy” and “unhealthy” perfectionism and impulsivity
Authors: Slof‐Op't Landt Margarita C.T. , Claes Laurence , van Furth Eric F. 
Published: May 2016

ABSTRACTObjectivePerfectionism and impulsivity are associated with eating disorders (EDs). The current study examines whether clinically relevant subgroups of women with EDs can be identified based on “healthy” and “unhealthy” perfectionism and impulsivity.MethodLatent profile analyses (LPA) were performed on data of 844 patients (DSM‐IV diagnosis: 381 anorexia nervosa, 146 bulimia nervosa, 56 binge‐eating disorder, 261 ED not otherwise specified). “Healthy” and “unhealthy” forms of perfectionism and impulsivity were assessed by the Frost Multidimensional Perfectionism Scale and the Dickman Impulsivity Inventory, respectively. The Eating Disorder Examination Questionnaire was completed to assess ED psychopathology. Furthermore, in 229 patients additional ED symptoms, depression, self‐esteem, obsessive‐compulsive symptoms, and personality features were assessed.ResultsThe LPA revealed four profiles; 1. “Healthy Impulsivity” (HI; n = 191), 2. “Unhealthy Impulsivity” (UI; n = 238), 3. “Healthy and Unhealthy Perfectionism” (HP + UP; n = 153), 4. “Healthy Perfectionism” (HP; n = 262). Patients belonging to the “HP + UP” and the “UI” classes reported higher levels of ED psychopathology. More severe comorbid symptoms (depressive, obsessive‐compulsive and self‐esteem) were found in the patients belonging to the “HP + UP” class. Patients from the “HP + UP” and “HP” classes had higher scores for the personality features Harm Avoidance, Persistence and Cooperativeness.DiscussionWomen with EDs could be meaningfully grouped according to perfectionism and impulsivity. These findings can be used to improve treatment matching and intervention strategies. The use of dimensional features, like perfectionism and impulsivity, in ED research, may enable the identification of fundamental underlying mechanisms and provide more insight into potential mechanisms that may drive or maintain disordered eating. © 2016 Wiley Periodicals, Inc.

Investigation of the seismic response of high‐rise buildings supported on tension‐resistant elastomeric isolation bearings
Authors: Lu Xilin , Wang Dong , Wang Shanshan 
Published: May 2016

SummaryIn many applications of seismic isolation, such as in high‐rise construction, lightweight construction, and structures with large height‐to‐width aspect ratios, significant tension forces can develop in bearings, raising concerns about the possible rupture of elastomeric bearings and the uplift of sliding bearings. In this paper, a novel tension‐resistant lead plug rubber bearing (TLRB) with improved tension‐resisting capabilities is developed and experimentally and numerically assessed. This TLRB consists of a common lead plug rubber bearing (LRB) and several helical springs. After describing the theory underlying the behavior of the TLRB, the mechanical properties of reduced‐scale prototype bearings are investigated through extensive horizontal and vertical loading tests. The test results indicate that TLRBs can improve the shear stiffness and tension resistance capacity even under significant tensile loads. A series of shaking table tests on scaled models of high‐rise buildings with different aspect ratios were conducted to investigate the dynamic performance of the TLRB and the seismic responses of base‐isolated high‐rise buildings. Three different cases were considered in the shaking table tests: a fixed base condition and the use of TLRB and LRB isolation systems. The results of the shaking table test show that (a) base‐isolated systems are effective in reducing the structural responses of high‐rise buildings; (b) an isolated structure's aspect ratio is an important factor influencing its dynamic response; (c) TLRBs can endure large tensile stresses and avoid rupture on rubber bearings under strong earthquakes; and (d) the experimental and numerical results of the responses of the models show good agreement.

Efficient approximation of Sparse Jacobians for time‐implicit reduced order models
Authors: Ştefănescu Răzvan , Sandu Adrian 
Published: May 2016

SummaryThis paper introduces a sparse matrix discrete interpolation method to effectively compute matrix approximations in the reduced order modeling framework. The sparse algorithm developed herein relies on the discrete empirical interpolation method and uses only samples of the nonzero entries of the matrix series. The proposed approach can approximate very large matrices, unlike the current matrix discrete empirical interpolation method, which is limited by its large computational memory requirements. The empirical interpolation indices obtained by the sparse algorithm slightly differ from the ones computed by the matrix discrete empirical interpolation method as a consequence of the singular vectors round‐off errors introduced by the economy or full singular value decomposition (SVD) algorithms when applied to the full matrix snapshots. When appropriately padded with zeros, the economy SVD factorization of the nonzero elements of the snapshots matrix is a valid economy SVD for the full snapshots matrix. Numerical experiments are performed with the 1D Burgers and 2D shallow water equations test problems where the quadratic reduced nonlinearities are computed via tensorial calculus. The sparse matrix approximation strategy is compared against five existing methods for computing reduced Jacobians: (i) matrix discrete empirical interpolation method, (ii) discrete empirical interpolation method, (iii) tensorial calculus, (iv) full Jacobian projection onto the reduced basis subspace, and (v) directional derivatives of the model along the reduced basis functions. The sparse matrix method outperforms all other algorithms. The use of traditional matrix discrete empirical interpolation method is not possible for very large dimensions because of its excessive memory requirements. Copyright © 2016 John Wiley & Sons, Ltd.

ObjectivesTo test the interrelation of the naturalistic course of depression in older people with long‐term support received.DesignLongitudinal cohort study.MethodsA sample of 277 adults age 55–85 years participating in the Longitudinal Aging Study Amsterdam, with clinically relevant depressive symptoms at baseline (scores ≥16 on the Center for Epidemiological Studies Depression Scale) were followed up over a period of 13 years. General estimating equations were used to examine the relation between depression course and emotional/instrumental support received over time. In addition, partner status, gender, and age were tested as modifiers.ResultsA 2‐way interaction between depression courses types and time showed significant differences in instrumental support received over time in older people with a late‐life depression. Three‐way interactions showed that associations between depression course and support variables were modified by gender and partner status.ConclusionBoth men and singles, with a chronic course of depression may be at risk to lose emotional and instrumental support over time. Professional attention is needed to prevent a chronic course of late‐life depression, and to preserve personal social networks. Copyright © 2016 John Wiley & Sons, Ltd.

Published: May 2016

ABSTRACTWe present a case of antenatal diagnosis of idiopathic dilatation of the pulmonary artery by three‐dimensional power Doppler imaging (HDliveFlow with silhouette mode). Two‐dimensional sonography clearly demonstrated a 10.4‐mm‐diameter fetal pulmonary artery (PA), whereas the aorta (Ao) diameter was 5.04 mm. HDliveFlow clearly demonstrated the spatial relationships and different sizes of PA and Ao. The PA size returned to normal (8.0 mm) on the 11th day after birth (Ao: 9.0 mm). HDliveFlow may be an adjunctive tool to two‐dimensional sonography to diagnose abnormalities of fetal great vessels. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:121–123, 2017;

ABSTRACTOzone and particle pollution are of concern for the Sydney basin, in particular during warm months (November to March) when pollution levels can exceed national standards. Previous studies on the relationship between synoptic circulation and air quality focused on high pollution days or aggregated air quality conditions over the region as a whole. This study provides both temporal and spatial analyses of the synoptic processes affecting warm‐month ozone and particle pollution in Sydney. A warm‐month synoptic catalogue was developed by applying the self‐organising map method to the NCEP/NCAR geopotential height reanalysis for south‐east Australia. The catalogue was linked to mesoscale meteorological features such as drainage flows and sea breezes, and subsequently to the spatial variability in air quality across the Sydney basin. The typical synoptic types commonly associated with high or low ozone and PM10 levels, as well as variations in visibility, were identified. The results suggest that, due to Sydney's subtropical coastal‐basin environment, the interaction between meso‐ and synoptic‐scale features determine local air quality conditions in the region, rather than the synoptic conditions alone. Emissions from bushfires appear to have considerable impacts on the synoptic modulation to visibility and PM10 levels, with such impacts tending to be more at a local scale. In contrast, no comparable impacts were found for ozone pollution. For ozone and visibility, the probability for an exceedance day under some synoptic types varied considerably over time, implying that there might have been a shift in the role of synoptic modulation to local air quality associated with changes in air emissions profiles. This study provides a leap in our understanding of the relationship between synoptic circulation and air quality in a coastal‐basin environment. The results are useful for improving air quality forecasting in Sydney, with the methodology developed readily applicable to similar regions elsewhere.

Published: May 2016

AbstractBACKGROUNDAlfalfa is considered a potential feedstock for biofuels; co‐products with value‐added uses would enhance process viability. This work evaluated dried alfalfa leaves for protein production and describes the functional properties of the protein.RESULTSDried alfalfa leaves contained 260 g kg−1 dry basis (DB) crude protein, with albumins being the major fraction (260 g kg−1 of total protein). Alkali solubilization for 2 h at 50 °C, acid precipitation, dialysis, and freeze‐drying produced a protein concentrate (600 g kg−1 DB crude protein). Alfalfa leaf protein concentrate showed moderate solubility (maximum 500 g kg−1 soluble protein from pH 5.5 to 10), excellent emulsifying properties (activity 158–219 m2 g−1 protein, stability 17–49 min) and minimal loss of solubility during heating at pH ≥ 7.0.CONCLUSIONSIt is technically feasible to extract protein with desirable emulsifying and heat stability properties from dried alfalfa leaves; however, the dried form may not be a practical starting material for protein production, given the difficulty of achieving high yields and high‐purity protein product. © 2016 Society of Chemical Industry
Environmentally friendly anodising process for structural bonding of titanium
Authors: Rico‐Oller B. , Mertens T. , Kolb M. , Wehr J. , Zheludkevich M. 
Published: May 2016

This paper evaluates the applicability of two wet‐chemical treatments for structural bonding of titanium alloy Ti6Al4V. The anodising processes, NaTESi and N4‐Process, are based on electrolytes containing sodium hydroxide and complexing agents, but while NaTESi process contains ethylenediaminetetraacetic acid, a particularly hazardous chemical, N4‐Process is a REACh compliant electrolyte. Scanning electron microscopy and transmission electron microscopy were employed to evaluate the oxide layer formed after the anodising processes. The long‐term durability and the resultant adhesion properties on titanium were assessed by means of floating‐roller‐peel test. Both investigated anodising processes lead to oxide layers revealing a highly porous nanostructure (thickness between 150–600 nm) according to scanning electron microscopy and transmission electron microscopy analyses. The mechanical tests lead to negligible differences between processes, performing higher peel resistance when compared to only alkaline etched samples, especially after 1000 hours ageing at 50 °C and 95 % relative humidity. The results indicate that N4‐Process is a promising treatment to enhance the long‐term durability of bonded titanium joints, especially under hot and wet conditions.

Published: May 2016

AbstractBackgroundLegalization of the medical use of cannabis for Parkinson's disease (PD) has bypassed the traditional drug‐approval process, leaving physicians with little evidence with which to guide patients.ObjectiveThe goal of this study was to gather data on the cannabis‐related prescribing practices and views regarding potential risks and benefits of cannabis among experts caring for patients with PD.MethodsAn anonymous, 73‐item online survey was conducted through an online service (SurveyMonkey) and included neurologists at all National Parkinson Foundation Centers of Excellence.ResultsFifty‐six responders represented centers across 5 countries and 14 states. 23% reported some formal education on cannabis. Eighty percent of responders had patients with PD who used cannabis, and 95% were asked to prescribe it. Fifty‐two percent took a neutral position on cannabis use with their patients, 9% discouraged use, and 39% encouraged it. Most believed that the literature supported use of cannabis for nausea (87%; n = 48), anxiety (60%; n = 33), and pain (86%; n = 47), but responses were divided with regard to motor symptoms. Most respondents expected that cannabis would worsen motivation (59%; n = 32), sleepiness (60%; n = 31), and hallucinations (69%; n = 37). In addition, most feared negative effects on short‐term memory (75%; n = 42), long‐term memory (55%; n = 31), executive functioning (79%; n = 44), and driving (96%; n = 54). Although many did not believe that cannabis should be recreational (50%; n = 28), most believed that it should be legalized for medicinal purposes (69.6%; n = 39).ConclusionsThis study provides data on the cannabis‐related practices, beliefs, and attitudes of expert PD physicians. There is a lack of consensus that likely reflects a general knowledge gap and paucity of data to guide clinical practice.
Handling boundaries with the one‐dimensional first‐order recursive filter
Authors: Mirouze Isabelle , Storto Andrea 
Published: May 2016

In variational data assimilation, a crucial task is to determine the background‐error covariance matrix B. The effect of B on a field is often modelled through a series of operators among which is a correlation operator. The recursive filter, when properly normalized to ensure the maximum of the solution is 1, is a convenient correlation operator and is widely used as such. Often, multi‐dimensional operators are constructed from the product of one‐dimensional operators. When their coefficients are calculated appropriately, the normalized one‐dimensional first‐order recursive filter applied N times models an autoregressive function of order N.In ocean data assimilation, an extra difficulty is to handle, within the correlation operator, the boundaries formed by the different coastlines or the bathymetry. Handling the east/west wrapping or polar folds in global configurations are also part of the issue. The purpose of this article is to set up a mathematical framework for using the recursive filter in ocean data assimilation and properly accounting for boundaries. Generally, these problems are dealt with by calculating proper normalization factors using costly methods, or extending the grid near boundaries. It is shown that the normalization factors can be calculated inexpensively through an analytical formula with a corrective term to handle properly the boundary when Neumann or Dirichlet boundary conditions are used.In its classical formulation however, the recursive filter uses Robin (third type) boundary conditions. This formulation can be slightly modified in order to account for Neumann, Dirichlet or periodic boundary conditions. To do so, extra coefficients are calculated through a simple recursive formula. In a global 1/4° analysis framework, this new formulation is shown to be less expensive and more accurate than the classical formulation associated with an appropriate grid extension.
Contemporary Review of Risk‐Stratified Management in Acute Uncomplicated and Complicated Diverticulitis

Published: May 2016

AbstractBackgroundAcute colonic diverticulitis is a common clinical condition. Severity of the disease is based on clinical, laboratory, and radiological investigations and dictates the need for medical or surgical intervention. Recent clinical trials have improved the understanding of the natural history of the disease resulting in new approaches to and better evidence for the management of acute diverticulitis.MethodsWe searched the Cochrane Library (years 2004–2015), MEDLINE (years 2004–2015), and EMBASE (years 2004–2015) databases. We used the search terms “diverticulitis, colonic” or “acute diverticulitis” or “divertic*” in combination with the terms “management,” “antibiotics,” “non‐operative,” or “surgery.” Registers for clinical trials (such as the WHO registry and the https://clinicaltrials.gov/) were searched for ongoing, recruiting, or closed trials not yet published.ResultsAntibiotic treatment can be avoided in simple, non‐complicated diverticulitis and outpatient management is safe. The management of complicated disease, ranging from a localized abscess to perforation with diffuse peritonitis, has changed towards either percutaneous or minimally invasive approaches in selected cases. The role of laparoscopic lavage without resection in perforated non‐fecal diverticulitis is still debated; however, recent evidence from two randomised controlled trials has found a higher re‐intervention in this group of patients.ConclusionsA shift in management has occurred towards conservative management in acute uncomplicated disease. Those with uncomplicated acute diverticulitis may be treated without antibiotics. For complicated diverticulitis with purulent peritonitis, the use of peritoneal lavage appears to be non‐superior to resection.
Low Temporal Stability of Excessive Video Game Use in German	Adolescents
Authors: Rothmund Tobias , Klimmt Christoph , Gollwitzer Mario 
Published: May 2016

Abstract. The popularity of digital games among adolescents has raised public and scientific concern about players drifting into excessive or pathological gaming patterns. Among the neglected issues in this area of research is the question of whether excessive gaming reflects a transient phenomenon during adolescence or a temporally stable pathological behavior that requires external intervention. In a correlational panel study with two points of measurement, we investigated the temporal stability of excessive gaming in German adolescents (N = 488; aged 12–17 years at Time 1) over a time lag of 1 year. Among the video game players in our sample, 2.8% were classified as excessive gamers at both points of measurement. The correlation of excessive gaming between T1 and T2 was found to be relatively moderate (r = .54). Detailed inspection revealed even lower stability scores for each single component of excessive gaming such as tolerance or conflict, with the most problematic elements (stealing, borrowing money because of gaming problems) displaying the lowest stabilities (r < .30). Thus, the results indicate that – at least for the large majority of adolescent players – excessive gaming is a transient and not a stable condition. Theoretical and policy implications are discussed.
