AbstractObjectivesThe main objective was to investigate the association between perfectionism and eating behaviour in a non‐clinical sample of adolescents of both genders.Method997 middle and high school students completed the Portuguese versions of the child‐adolescent perfectionism scale (CAPS) and of the eating attitudes test ‐25 (EAT‐ 25).ResultsIn both genders, the perfectionism total score and the sociallyprescribed perfectionism (SPP) score were positive and significantly correlated with the EAT total score and with all EAT dimensions: Drive for Thinness (DT), Bulimic Related Behaviour (BRB), Social Pressure to Eat (SPE). In girls, self‐oriented perfectionism (SOP) was also associated with the EAT total score and its dimensions, whereas in boys it was only associated with EAT total score and DT. In both genders SPP was a useful predictor of the EAT‐25 total score and of all its dimensions. In which respects SOP, there were some gender differences showing that in boys this dimension should not be considered a predictor of eating behaviours.ConclusionThese results confirm that high levels of perfectionism (SOP and SPP) are associated with abnormal eating behaviour in both genders.

AbstractObjectiveThis prospective study examined whether psychological variables related to the transdiagnostic theory of eating disorders measured at admission predicted length of time to reach 85 per cent of ideal body weight (IBW) among underweight adolescents hospitalized for an eating disorder.MethodThirty‐three girls (aged 12–17) weighing below 85 per cent of IBW, admitted to an inpatient and/or partial hospitalization eating disorder programme completed self‐report measures at admission. Cox regression tested whether scores on admission measures predicted time to reach 85 per cent of IBW.ResultsAfter controlling for IBW at admission, higher self‐esteem and lower perfectionism predicted shorter time to reach 85 per cent of IBW, with emotion regulation as a marginally significant predictor.ConclusionSelf‐esteem and perfectionism may be predictors of responsiveness to weight‐gain efforts during hospitalization. Further studies are necessary to determine whether these variables might be appropriate targets for intervention to promote weight gain in underweight girls with eating disorders.

Authors: Zhao Erjun , Wang Jinping , Wu Zhijian 
Published: May 2010

AbstractThe structural stability and phase transition of osmium and ruthenium carbides (OsC and RuC) were investigated by first principles. Nine structures were considered for each carbide. Zinc blende structure has the lowest energy among the considered structures at ambient conditions for both carbides. For OsC at elevated pressures, the most stable phase is zinc blende structure from 0 to 10 GPa, FeSi from 10 to 32 GPa. In these two structures, Os atom is fourfold coordinated. From 32 to 40 GPa, tungsten carbide (WC) and NiAs are energetically competitive with Os atom sixfold coordinated. NiAs becomes energetically the most stable structure above 40 GPa. For RuC, zinc blende structure is the most stable from 0 to 20 GPa. From 20 to 100GPa, WC structure is the most stable. © 2010 Wiley Periodicals, Inc. J Comput Chem 2010

AbstractThe Mental Health Surveillance Study (MHSS) is an ongoing initiative by the Substance Abuse and Mental Health Services Administration (SAMHSA) to monitor the prevalence of serious mental illness (SMI) among adults in the USA. In 2008, the MHSS used data from clinical interviews to calibrate mental health data from the National Survey on Drug Use and Health (NSDUH) for estimating the prevalence of SMI based on the full NSDUH sample. The clinical interview used was the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM‐IV; SCID). NSDUH interviews were administered via audio computer‐assisted self‐interviewing (ACASI) to a nationally representative sample of the population aged 12 years or older. A total of 46 180 NSDUH interviews were completed with adults aged 18 years or older in 2008. The SCID was administered by mental health clinicians to a sub‐sample of 1506 adults via telephone. This paper describes the MHSS calibration study procedures, including information on sample selection, instrumentation, follow‐up, data quality protocols, and management of distressed respondents.

AbstractThe Mental Health Surveillance Study (MHSS) is an ongoing initiative by the Substance Abuse and Mental Health Services Administration to develop and implement methods for measuring the prevalence of serious mental illness (SMI) among adults in the USA. The 2008 MHSS used data from clinical interviews administered to a sub‐sample of respondents to calibrate mental health screening scale data from the National Survey on Drug Use and Health (NSDUH) for estimating the prevalence of SMI in the full NSDUH sample. The mental health scales included the K6 screening scale of psychological distress (administered to all respondents) along with two measures of functional impairment (each administered to a random half‐sample of respondents): the World Health Organization Disability Assessment Schedule (WHODAS) and the Sheehan Disability Scale (SDS). The Structured Clinical Interview for DSM‐IV (SCID) was administered to a sub‐sample of 1506 adult NSDUH respondents within 4 weeks of completing the NSDUH interview. Results indicate that while SMI prediction accuracy of the K6 is improved by adding either the WHODAS or the SDS to the prediction equation, the models with the WHODAS are more robust. The results of the calibration study and methods used to derive prevalence estimates of SMI are presented. Copyright © 2010 John Wiley & Sons, Ltd.
Improving the K6 short scale to predict serious emotional disturbance in adolescents in the USA

Published: May 2010

AbstractEffective screening for emotional and behavioral disorders among youth requires brief screening scales with good validity to identify youth requiring further evaluation and to estimate prevalence of target disorders in populations of interest such as schools or neighborhoods. This paper examines the psychometric properties of a very short (six‐item) screening scale, the K6, to assess serious emotional disturbance (SED) among youth. The K6, which is made up of symptoms of depression and anxiety, has been shown in previous research to be a strong predictor of serious mental illness (SMI) in adults, but no information is available on the ability of the scale to screen for SED among youth. The current report examines the K6 as a screen for SED in a national survey of US adolescents, the National Comorbidity Survey Replication Adolescent Supplement (NCS‐A). The K6 is shown to provide fairly good prediction of SED [area under curve (AUC) = 0.74] that is somewhat higher for internalizing (AUC = 0.80) than behavior (AUC = 0.75) disorders. Based on this result, we augmented the K6 with questions about symptoms of behavior disorders. This improved prediction of SED (from AUC = 0.74 to AUC = 0.83) as well as of SED associated with pure behavior disorders (from AUC = 0.53 to AUC = 0.78). These results show that although the symptoms of depression and anxiety in the K6 are sufficient to detect SMI among adults, high rates of behavior disorders among adolescents require indicators of behavior disorders to be added to the K6 to screen adequately for adolescent SED.

Estimating prevalence of serious emotional disturbance in schools using a brief screening scale

AbstractInformation about the prevalence of serious mental illness (SMI) among adults or serious emotional disturbance (SED) among youth in small domains such as counties, states, or schools is valuable for mental health policy planning purposes, but prohibitively expensive to collect with semi‐structured surveys. Commonly used synthetic estimation methods yield imprecise estimates. An improved method is described here that combines information about socio‐demographic covariates with screening scale scores obtained from a sample of individuals, using a prediction equation derived from a Bayesian multilevel regression model with bivariate outcomes fitted to a larger population survey. This method is illustrated using K6 screening scale scores to predict school‐level prevalence of SED in the sample of 282 schools that participated in the National Comorbidity Survey Replication Adolescent Supplement. Respondents completed a diagnostic interview that was used to define DSM‐IV SED. SED prevalence varied significantly across schools and was strongly correlated with aggregate K6 scores (ρ = 0.70). Calculations suggest that near‐maximum precision of school‐level SED prevalence estimates could be attained with K6 samples of 200 students per school. This modeling approach holds great promise for generating accurate estimates of SMI/SED in small‐area planning units based on K6 scores collected in ongoing health tracking surveys.

Screening for serious mental illness: methodological studies of the K6 screening scale
Authors: Wittchen Hans‐Ulrich 
Published: May 2010

AbstractThe K6 scale is a shortened version of the K10, a 10‐question scale originally developed to provide an efficient population‐level screen for serious mental disorders (SMI) in the USA. Evidence that the six‐item shortened version performed as well as the original 10‐item version, coupled with strong psychometric properties, led to rapid dissemination and replicated validation of the K6 in a number of other countries around the world. Based on these results, the K6 is now often included in large general‐purpose government health tracking surveys in a number of different countries. Until now, though, the scoring rules for the K6 in these surveys were inconsistent. The first paper in this special issue introduces the K6 scale and summarizes the results of a series of investigations to resolve these inconsistencies by providing optimal scoring rules for the K6 in 14 countries. Subsequent papers explore the usefulness of the K6 to screen for serious emotional disturbance among adolescents and report findings from validation efforts based on independent diagnostic assessments as well as of other measures of impairment and disability (World Health organization Disability Assessment Scale). Finally a highly innovative analysis using a Bayesian multilevel modeling approach is presented, designed to estimate the prevalence of SMI in small areas, such as cities, states, or schools, from surveys carried out in a larger population that includes only relatively small samples of respondents in each of the areas in which prevalence estimates are to be made. Taken together, these studies demonstrate that the K6 is an efficient and useful screening tool. The psychometric and methodological explorations will hopefully stimulate additional interest in the use of short screening scales in large‐scale general health surveys to supplement the more in‐depth information obtained in periodic psychiatric epidemiological surveys on the basis of diagnostic interviews.

Steady‐state diffusion‐weighted imaging: theory, acquisition and analysis
Authors: McNab Jennifer A. , Miller Karla L. 
Published: May 2010

AbstractSteady‐state diffusion‐weighted imaging (DWI) has long been recognized to offer potential benefits over conventional spin‐echo methods. This family of pulse sequences is highly efficient and compatible with three‐dimensional acquisitions, which could enable high‐resolution, low‐distortion images. However, the same properties that lead to its efficiency make steady‐state imaging highly susceptible to motion and create a complicated signal with dependence on T1, T2and flip angle. Recent developments in gradient hardware, motion‐mitigation techniques and signal analysis offer potential solutions to these problems, reviving interest in steady‐state DWI. This review offers a description of steady‐state DWI signal formation and provides an overview of the current methods for steady‐state DWI acquisition and analysis.

Measuring the acute effect of insulin infusion on ATP turnover rate in human skeletal muscle using phosphorus‐31 magnetic resonance saturation transfer spectroscopy
Authors: Lim Ee Lin , Hollingsworth Kieren G. , Thelwall Peter E. , Taylor Roy 
Published: May 2010

AbstractMitochondrial dysfunction has been proposed to underlie the insulin resistance of type 2 diabetes. However, the relative time course of insulin action in stimulating ATP turnover rate and glucose uptake in skeletal muscle has not been examined. These two parameters were measured in young healthy subjects using the 31P MRS saturation transfer method in conjunction with the euglycaemic hyperinsulinaemic clamp technique respectively. Glucose infusion rate rose rapidly from 0 to 2.90 ± 0.11 mg/kgffm/min during the first 10 min of insulin infusion and further to 6.17 ± 0.57 mg/kgffm/min between 15 and 45 min. In contrast, baseline ATP turnover rate was 9.0 ± 0.4 µmol/g/min of muscle and did not change during the first 45 min of insulin infusion. Between 50 and 80 minutes ATP turnover rate increased by 8% and remained steady to 150 minutes (9.7 ± 0.5 µmol/g/min of muscle, p = 0.03 vs baseline). The in vivo time course of insulin stimulation of skeletal muscle ATP turnover rate is not consistent with a rate limiting effect upon the initiation of insulin‐stimulated glycogen synthesis.

Published: May 2010

AbstractA new method has been developed to reduce the number of phase‐encoding steps in a multi‐echo spin‐echo imaging sequence allowing fast T2 mapping without loss of spatial resolution. In the proposed approach, the k‐space data at each echo time were undersampled and a reconstruction algorithm that exploited the temporal correlation of the MR signal in k‐space was used to reconstruct alias‐free images. A specific application of this algorithm with multiple‐receiver acquisition, offering an alternative to existing parallel imaging methods, has also been introduced. The fast T2 mapping method has been validated in human brain T2 measurements in a group of nine volunteers with acceleration factors up to 3.4. The results demonstrated that the proposed method exhibited excellent linear correlation with the regular T2 mapping with full sampling and achieved better image reconstruction and T2 mapping with respect to SNR and reconstruction artifacts than the selected reference acceleration techniques. The new method has also been applied for quantitative tracking of injected magnetically labeled breast cancer cells in the rat brain with acceleration factors of 1.8 and 3.0. The proposed technique can provide an effective approach for accelerated T2 quantification, especially for experiments with single‐channel coil when parallel imaging is not applicable.

Statin and NSAID use and prostate cancer risk
Authors: Coogan Patricia F. , Kelly Judith Parsells , Strom Brian L. , Rosenberg Lynn 
Published: May 2010

AbstractPurposeSome studies have reported reduced risks of advanced, but not early, prostate cancer among statin users, and one study found a reduced risk only among statin users who had also used non‐steroidal anti‐inflammatory drugs (NSAIDs). We have previously reported no association between statin use and prostate cancer in our hospital‐based Case Control Surveillance Study. The purpose of the present analyses was to update the findings by cancer stage and to evaluate the joint use of statins and NSAIDs.MethodsCases were 1367 men with prostate cancer and controls were 2007 men with diagnoses unrelated to statin or NSAID use. We used multivariable logistic regression analyses to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for statin use compared with no use, and joint use of statin and NSAIDs compared with use of neither.ResultsThe odds ratio among regular statin users was 1.1 (95%CI 0.9–1.5), and odds ratios were similar among early and late stage cancers. The odds ratio among joint statin and NSAID users was 1.1 (95%CI 0.7–1.6).ConclusionThe present results do not support a protective effect of statin use, or statin and NSAID use, on the risk of advanced prostate cancer.

AbstractWe successfully grew Gallium nitride (GaN) films on MgAl2O4 (111) substrates using low temperature pulsed laser deposition (PLD). X‐ray diffraction rocking curves revealed the high quality of as‐grown GaN with its full width at half maximum (FWHM) along [0002] as small as 0.08°. Atomic force microscopy images showed very smooth surface of as‐grown GaN and indicated a two‐dimensional growth. High‐resolution transmission electron microscopy showed high structural perfection of GaN films. The crystalline structure for MgAl2O4 substrate from its body to its top part adjacent to GaN epitaxy kept constant, and the interface between GaN and MgAl2O4 was atomically abrupt. We attribute the high quality of as‐grown GaN films to the well‐controlled Mg atom evaporation from MgAl2O4 substrate surface owing to the application of low growth temperature in PLD: on the one hand, it avoids the severe interfacial reaction that is very likely to take place in conventional MOCVD or MBE growth, and hence makes the epitaxial growth possible; on the other hand, it conserves the crystalline structure of the substrate surface, and consequently takes good advantage of the small lattice mismatch between GaN and MgAl2O4.

AbstractAtomic layer deposition (ALD) was used to fabricate transparent and conductive thin films of ZnO. Two hundred‐nano metre thick ZnO films were deposited on glass substrates at low growth temperatures varied between 120 and 240 °C. As zinc and oxygen precursors we used diethylzinc (DEZn) and deionized water, respectively. To find optimal film parameters, the structure, surface morphology, optical and electrical measurements were carried on. The films obtained at 200 °C show the highest carrier concentration (∼1020 cm−3) and the lowest resistivity (2 × 10−3 Ω cm). The films exhibit mobilities up to 37 cm2/Vs that we associate to the process technology used. An important point of our approach was that the films studied were not intentionally doped (with Al or other group III elements) but the high electrical conductivity was achieved by playing with the sample stoichiometry and growth conditions.

AbstractIn recent years, Zn1−xMgxO has attracted the attention of many researchers as its physical behaviour can be suitably controlled by varying the Zn/Mg ratio. The superior advantages associated with Zn1−xMgxO make this material as a potential candidate for application in Cu(InGa)Se2‐based solar cells. In the present investigation, Zn1−xMgxO films have been prepared by spray pyrolysis at 300 °C and subsequently annealed in argon and oxygen ambience at temperatures that vary in the range, 100–500 °C. The changes occurred in the physical characteristics of the layers as a function of annealing temperature have been studied. The influence of annealing on the structure, topography, opto‐electronic and photoluminescence properties was found to be significant. The results have been presented and discussed.

Published: May 2010

AbstractThe performance of top‐gate thin film transistors with solution processed zinc oxide (ZnO) channel layer and poly(4‐vinylphenol) (PVP) gate dielectric have been investigated. The transparency of the PVP film was more than 80% in the visible region, indicating that PVP can be used as a potential dielectric layer for transparent electronics. The TFTs with as‐prepared ZnO as the channel layer showed a saturation field effect mobility of 6.4 × 10−3 cm2/Vs with an on/off ratio of 30. The performances of the TFTs were enhanced after oxygen annealing of the ZnO channel layer prior to PVP deposition. The TFTs with 1 h oxygen annealed ZnO as the channel layer showed a saturation mobility of 0.05 cm2/Vs with an on/off ratio of 2.1 × 102. The obtained results are encouraging for fabrication of all solution processed ZnO based TFTs for cost effective technological applications.
