abstract = {OBJECTIVE: Several co-infections have been shown to impact the progression of HIV-1 infection. We sought to determine if treatment of helminth co-infection in HIV-1-infected adults impacted markers of HIV-1 disease progression. DESIGN: To date, there have been no randomized trials to examine the effects of soil-transmitted helminth eradication on markers of HIV-1 progression. METHODS: A randomized, double-blind, placebo-controlled trial of albendazole (400 mg daily for 3 days) in antiretroviral-naive HIV-1-infected adults (CD4 cell count >200 cells/microl) with soil-transmitted helminth infection was conducted at 10 sites in Kenya (Clinical Trials.gov NCT00130910). CD4 and plasma HIV-1 RNA levels at 12 weeks following randomization were compared in the trial arms using linear regression, adjusting for baseline values. RESULTS: Of 1551 HIV-1-infected individuals screened for helminth infection, 299 were helminth infected. Two hundred and thirty-four adults were enrolled and underwent randomization and 208 individuals were included in intent-to-treat analyses. Mean CD4 cell count was 557 cells/microl and mean plasma viral load was 4.75 log10 copies/ml at enrollment. Albendazole therapy resulted in significantly higher CD4 cell counts among individuals with Ascaris lumbricoides infection after 12 weeks of follow-up (+109 cells/microl; 95% confidence interval +38.9 to +179.0, P = 0.003) and a trend for 0.54 log10 lower HIV-1 RNA levels (P = 0.09). These effects were not seen with treatment of other species of soil-transmitted helminths. CONCLUSION: Treatment of A. lumbricoides with albendazole in HIV-1-coinfected adults resulted in significantly increased CD4 cell counts during 3-month follow-up. Given the high prevalence of A. lumbricoides infection worldwide, deworming may be an important potential strategy to delay HIV-1 progression.},

title = {Tolerance of suicide, religion and suicide rates; an ecological and individual-level study in 19 western countries},
abstract = {Background. Negative associations between religion and suicide, in individuals and countries, may be mediated by the degree to which suicide is tolerated. Methods. Linear regression was used to examine ecological associations between suicide tolerance, religion and suicide rates in 19 Western countries in 1989/90. Logistic regression was used to study associations between suicide tolerance and strength of religious belief in 28085 individuals in these countries. The concept of effect modifying function was used to examine whether the strength of the association between suicide tolerance and religious belief in individuals depended on the extent of religious belief in their country. Results. Higher female suicide rates were associated with lower aggregate levels of religious belief and, less strongly, religious attendance. These associations were mostly attributable to the association between higher tolerance of suicide and higher suicide rates. In the 28085 subjects suicide tolerance and the strength of religious belief were negatively associated even after adjustment for other religious and sociodemographic variables and general tolerance levels (odds ratios: men 0·74 (95% CI 0·58--0·94), women 0·72 (95% CI 0·60--0·86)). This negative individual- level association was more pronounced in more highly religious countries but this modifying effect of the religious context was apparent for men only. Conclusions. Ecological associations between religious variables and suicide rates are stronger for women than men, stronger for measures of belief than observance and mediated by tolerance of suicide. In individuals, stronger religious beliefs are associated with lower tolerance of suicide. Personal religious beliefs and, for men, exposure to a religious environment, may protect against suicide by reducing its acceptability.},

abstract = {Admixture mapping is an economical and powerful approach for localizing disease genes in populations of recently mixed ancestry and has proven successful in African Americans. The method holds equal promise for Latinos, who typically inherit a mix of European, Native American, and African ancestry. However, admixture mapping in Latinos has not been practical because of the lack of a map of ancestry-informative markers validated in Native American and other populations. To address this, we screened multiple databases, containing millions of markers, to identify 4,186 markers that were putatively informative for determining the ancestry of chromosomal segments in Latino populations. We experimentally validated each of these markers in at least 232 new Latino, European, Native American, and African samples, and we selected a subset of 1,649 markers to form an admixture map. An advantage of our strategy is that we focused our map on markers distinguishing Native American from other ancestries and restricted it to markers with very similar frequencies in Europeans and Africans, which decreased the number of markers needed and minimized the possibility of false disease associations. We evaluated the effectiveness of our map for localizing disease genes in four Latino populations from both North and South America.},

abstract = {Mixture modeling is a widely applied data analysis technique used to identify unobserved heterogeneity in a population. Despite mixture models' usefulness in practice, one unresolved issue in the application of mixture models is that there is not one commonly accepted statistical indicator for deciding on the number of classes in a study population. This article presents the results of a simulation study that examines the performance of likelihood-based tests and the traditionally used Information Criterion (ICs) used for determining the number of classes in mixture modeling. We look at the performance of these tests and indexes for 3 types of mixture models: latent class analysis (LCA), a factor mixture model (FMA), and a growth mixture models (GMM). We evaluate the ability of the tests and indexes to correctly identify the number of classes at three different sample sizes (n D 200, 500, 1,000). Whereas the Bayesian Information Criterion performed the best of the ICs, the bootstrap likelihood ratio test proved to be a very consistent indicator of classes across all of the models considered.},

The purpose of this paper is to draw the attention to a number of issues relevant for a successful integration of PRO measures into the daily work flow of busy clinical settings. METHODS: The paper summarizes the results from a breakout session held at an ISOQOL special topic conference for PRO measures in clinical practice in 2007. RESULTS: Different methodologies of collecting PROs are discussed, and the support needed for each methodology is highlighted. The discussion is illustrated by practical real-life examples from early adaptors who administered paper-pencil, or electronic PRO assessments (ePRO) for more than a decade. The paper also reports about new experiences with more recent technological developments, such as SmartPens and Computer Adaptive Tests (CATs) in daily practice. CONCLUSIONS: Methodological and logistical issues determine the resources needed for a successful integration of PRO measures into daily work flow procedures and influence significantly the usefulness of PRO data for clinical practice.},

abstract = {There is a growing interest in studying natural variation in human gene expression. Studies mapping genetic determinants of expression profiles are often carried out considering the expression of one gene at a time, an approach that is computationally intensive and may be prone to high false-discovery rate because the number of genes under consideration often exceeds tens of thousands. We present an exploratory method for investigating such data and apply it to the data provided as Problem 1 of Genetic Analysis Workshop 15 (GAW15). In multivariate analysis, canonical correlation analysis is a common way to inspect the relationship between two sets of variables based on their correlation. It determines linear combinations of all variables from each data set such that the correlation between the two linear combinations is maximized. However, due to the large number of genes, linear combinations involving all single-nucleotide polymorphism (SNP) loci and gene expression phenotypes lack biological plausibility and interpretability. We introduce sparse canonical correlation analysis, which examines the relationships of many genetic loci and gene expression phenotypes by providing sparse linear combinations that include only a small subset of loci and gene expression phenotypes. These correlated sets of variables are sufficiently small for biological interpretability and further investigation. Applying this method to the GAW15 Problem 1 data, we identified groups of 41 loci and 150 gene expressions with the highest between-group correlation of 43%.},

abstract = {Gray matter volume and functional abnormalities have been reported in language-related cortex in schizophrenia patients with auditory hallucinations. Such abnormalities might denote abnormal cortical folding development, which can now be investigated using gyrification measures. Anatomic magnetic resonance images (MRIs) were obtained from 30 schizophrenia patients screened for resistant auditory hallucinations and 28 control subjects. We searched for overall gyrification abnormalities in the whole cortex as well as localized abnormalities in language-related cortex, assuming that gyrification is associated with brain sulcation. A fully automated method was applied to MRIs to extract, label and measure the sulcus area in the whole cortex. Gyrification was assessed using both global and local sulcal indices, respectively the ratio between total sulcal area, or area of each labeled sulcus, and outer cortex area. For both hemispheres, the patients had a lower global sulcal index. The local sulcal index decrease was not homogeneous across the whole cortex. It was more significant in the superior temporal sulcus bilaterally, in the left middle frontal sulcus and in the diagonal branch of left sylvian fissure (Broca's area). Findings suggest abnormalities in cortical gyrification in these patients. Sulcal abnormalities in language-related cortex might underlie these patients' particular vulnerability to hallucinations.},

abstract = {OBJECTIVE: In attempting to explain the familial predisposition to panic disorder, most studies have focused on the heritability of physiologic characteristics (e.g., CO2 sensitivity). A heretofore unexplored possibility is that a psychological characteristic that predisposes to panic-anxiety sensitivity-might be inherited. In this study, the authors examined the heritability of anxiety sensitivity through use of a twin group. METHOD: Scores on the Anxiety Sensitivity Index were examined in a group of 179 monozygotic and 158 dizygotic twin pairs. Biometrical model fitting was conducted through use of standard statistical methods. RESULTS: Broad heritability estimate of the Anxiety Sensitivity Index as a unifactorial construct was 45%. Additive genetic effects and unique environmental effects emerged as the primary influences on anxiety sensitivity. There was no evidence of genetic discontinuity between normal and extreme scores on the Anxiety Sensitivity Index. CONCLUSIONS: This study suggests that one psychological risk factor for the development of panic disorder-anxiety sensitivity-may have a heritable component. As such, anxiety sensitivity should be considered in future research on the heritability of panic disorder.},

A sample of 2517 Australian twins aged over 50 between 1993 and 1995 returned completed self-reported measures of Self-directedness, Cooperativeness, and Self-transcendence from Cloninger's Temperament and Character Inventory. Many of these twins had participated in a 1988 study containing Cloninger's temperament measures of Harm Avoidance, Novelty Seeking, Reward Dependence and Persistence. Contrary to theoretical expectations, univariate analyses revealed that familial aggregation for the character dimensions could be entirely explained by additive gene action alone. Although temperament explained 26, 37 and 10% of additive genetic variance in Self-directedness, Cooperativeness and Self-transcendence, respectively, seven genetic factors were required to explain the genetic variance among the TPQ dimensions, and almost all of the non-shared environmental variance was unique to each dimension of character. Our results indicate that the inclusion of all seven dimensions in a taxonomy of personality is warranted.},

title = {Refer efficiently: Use less informative expressions for more predictable meanings},
abstract = {We present the results of a large-scale web experiment inves- tigating comprehenders' ability to guess upcoming referents in an unfolding discourse. Participants were given a text that had been cut off just before a noun phrase, and attempted to guess which previously mentioned referent, if any, would be mentioned next. Our results show that writers are more likely to refer using a pronoun or proper name rather than a full NP when comprehenders have less uncertainty about the upcom- ing referent, and are more likely to use names than pronouns when comprehenders all tend to makes guesses to one or a few incorrect referents. These effects hold beyond other possible influences on the choice of referring expression type. Our results support addressee-oriented accounts of referring form choice (e.g. Brennan {\&} Clark, 1996; Arnold, 2008) and suggest that language is a rational solution to the problem of commu- nication: shorter and less informative expressions are favoured when less information is sufficient to carry the message (e.g. Jaeger, 2006; van Son {\&} Pols, 2003).},

abstract = {Both Multilevel Models (MLM) and Rasch Models (RM) are standard tools for the analysis of latent variables: RM are measure models, MLM are linear models for data nested in a hierarchical structure. More recently some authors have showed the al- gebraic equivalence between RM and Hierarchical Generalized Linear Models (HGLM). The aim of this paper is to compare two different approaches. The first is a two steps approach: RM is used to measure the level of a latent variable and then MLM is used to identify individual and contextual variables that influence the level. The sec- ond approach consider the HGLM with three levels. To illustrate the comparison analy- sis an application with university evaluation data is carried out.},

title = {Testing a model of association between patient identified problems and responses to global measures of health in low back pain patients: a prospective study},
abstract = {BACKGROUND: Self-rated health status has been shown to be related to physical function. Therefore, changes in functional ability should be associated with changes in general health. However, functional needs may vary greatly between individuals. The purpose of this study was to propose and test a model of association between patient identified functional problems and responses to global measures of health in low back pain patients. METHODS: Participants in a low back pain clinical trial were followed up for 12 months. A series of analyses were undertaken using the Jonckheere-Terpstra test and chi-square for trends to determine the associations between two individualised items related to function, and measures of "overall improvement in condition", "general health status" and performance of "usual activities". RESULTS: Significant associations between responses to the five items were found. Performance of usual activities is significantly associated with ratings of general health status (p < 0.001) and overall condition of the back (p < 0.001). The extent to which the patient identified problems influence an individual's perception on multi-task performance is dependent upon the degree of difficulty and level of importance attached to these problems. CONCLUSION: The relationship between patient identified problems and responses to global measures of health is complex. The explanatory model proposed here may improve our understanding of these interactions. TRIAL REGISTRATION: ISRCTN 32765488.},

title = {Adolescent axis I and personality disorders predict quality of life during young adulthood},
abstract = {PURPOSE: To investigate and compare the prospective association of adolescent Axis I mental disorder and personality disorder (PD) with young adult quality of life (QOL) in the general population. METHODS: Seven hundred fifty mothers and youths participating in a prospective longitudinal community-based study were interviewed. Mental disorders were measured at a mean age 16 years. QOL as the outcome indicators were assessed at a mean age 22. RESULTS: Adolescent Axis I disorder predicted elevated negative affect and higher levels of stress some 6 years later. Adolescent PD predicted elevated negative affect and higher levels of stress, and also problems in social support and relationships, and poorer residential, mobility, and financial and health resources in adulthood. Youths with both Axis I disorder and one or more PDs had the worst outcomes with regard to health problems, stressful occupational or educational settings, and resources, net of the effects of adolescent health problems. Nevertheless, some aspects of adult QOL were not significantly related to adolescent disorder, including a positive perspective on the future, own morale in a chosen occupation or educational setting, or the amount of autonomy experienced in that setting. CONCLUSIONS: Among adolescents in the community, PDs during adolescence may have a more adverse impact on young adult QOL than do Axis I disorders. A combination of Axis I and PD may represent a particular risk for new physical health problems and resource inadequacy, including poor access to health care.},

title = {Selection bias in gene extraction on the basis of microarray gene-expression data},
abstract = {In the context of cancer diagnosis and treatment, we consider the problem of constructing an accurate prediction rule on the basis of a relatively small number of tumor tissue samples of known type containing the expression data on very many (possibly thousands) genes. Recently, results have been presented in the literature suggesting that it is possible to construct a prediction rule from only a few genes such that it has a negligible prediction error rate. However, in these results the test error or the leave-one-out cross-validated error is calculated without allowance for the selection bias. There is no allowance because the rule is either tested on tissue samples that were used in the first instance to select the genes being used in the rule or because the cross-validation of the rule is not external to the selection process; that is, gene selection is not performed in training the rule at each stage of the cross-validation process. We describe how in practice the selection bias can be assessed and corrected for by either performing a cross-validation or applying the bootstrap external to the selection process. We recommend using 10-fold rather than leave-one-out cross-validation, and concerning the bootstrap, we suggest using the so-called .632+ bootstrap error estimate designed to handle overfitted prediction rules. Using two published data sets, we demonstrate that when correction is made for the selection bias, the cross-validated error is no longer zero for a subset of only a few genes.},

title = {Quality of life at the end of life},
abstract = {BACKGROUND: Little is known about self-perceived quality of life (QOL) near the end of life, because such information is difficult to collect and to interpret. Here, we describe QOL in the weeks near death and determine correlates of QOL over time, with emphasis on accounting for death and missing data. METHODS: Data on QOL were collected approximately every week in an ongoing randomized trial involving persons at the end of life. We used these data to describe QOL in the 52 weeks after enrollment in the trial (prospective analysis, N = 115), and also in the 10 weeks just prior to death (retrospective analysis, N = 83). The analysis consisted of graphs and regressions that accounted explicitly for death and imputed missing data. RESULTS: QOL was better than expected until the final 3 weeks of life, when a terminal drop was observed. Gender, race, education, cancer, and baseline health status were not significantly related to the number of "weeks of good-quality life" (WQL) during the study period. Persons younger than 60 had significantly higher WQL than older persons in the prospective analysis, but significantly lower WQL in the retrospective analysis. The retrospective results were somewhat sensitive to the imputation model. CONCLUSION: In this exploratory study, QOL was better than expected in persons at the end of life, but special interventions may be needed for persons approaching a premature death, and also for the last 3 weeks of life. Our descriptions of the trajectory of QOL at the end of life may help other investigators to plan and analyze future studies of QOL. Methodology for dealing with death and the high amount of missing data in longitudinal studies at the end of life needs further investigation.},

title = {Effect of Noncompensatory Multidimensionality on Separate and Concurrent estimation in IRT Observed Score Equating},
abstract = {In this article, the results of a simulation study comparing the performance of separate and concurrent estimation of a unidimensional item response theory (IRT) model applied to multidimensional noncompensatory data are reported. Data were simulated according to a two-dimensional noncompensatory IRT model for both equivalent and nonequivalent groups designs. The criteria used were the accuracy of estimating a distribution of observed scores, and the accuracy of IRT observed score equating. In general, unidimensional concurrent estimation resulted in lower or equivalent total error than separate estimation, although there were a few cases where separate estimation resulted in slightly less error than concurrent estimation. Estimates from the correctly specified multidimensional model generally resulted in less error than estimates from the unidimensional model. The results of this study, along with results from a previous study where data were simulated using a compensatory multidimensional model, make clear that multidimensionality of the data affects the relative performance of separate and concurrent estimation, although the degree to which the unidimensional model produces biased results with multidimensional data depends on the type of multidimensionality present.},

abstract = {The multiple regression analysis of twin data in which a cotwin's score is predicted from that of a proband (the member of a twin pair selected because of a deviant score) and the coefficient of relationship provides a powerful test of genetic etiology (DeFries and Fulker: Behav Genet 15:467-473, 1985). Moreover, when an augmented model containing an interaction term is fitted to the same data set, direct estimates of heritability (h2) and the proportion of variance owing to shared environmental influences (c2) are also obtained. In the present paper, the expected partial regression coefficients estimated from these models are derived, and the flexibility of the general approach is illustrated. An extended model is formulated for the analysis of data from combined samples of affected and control twin pairs that yields tests for differential h2 and c2 in the two groups as well as pooled estimates of these parameters. The application of these models is illustrated by an analysis of data from reading-disabled and control twin pairs. Because of the ease, flexibility, and utility of the multiple regression analysis of twin data, it is an appealing alternative to more traditional model-fitting approaches.},

abstract = {OBJECTIVE: The purpose of this study was to test a life span health behavior model in which educational attainment and health behaviors (eating habits, smoking, and physical activity) were hypothesized as mechanisms to account for relations between teacher ratings of childhood personality traits and self-reported health status at midlife. DESIGN: The model was tested on 1,054 members of the Hawaii Personality and Health cohort, which is a population-based cohort participating in a longitudinal study of personality and health spanning 40 years from childhood to midlife. OUTCOME: Childhood Agreeableness, Conscientiousness, and Intellect-Imagination influenced adult health status indirectly through educational attainment, healthy eating habits, and smoking. Several direct effects of childhood traits on health behaviors and health status were also observed. CONCLUSION: The model extends past associations found between personality traits and health behaviors or health status by identifying a life-course pathway based on the health behavior model through which early childhood traits influence adult health status. The additional direct effects of personality traits indicate that health behavior mechanisms may not provide a complete account of relations between personality and health.},

title = {Validation of the NHANES ADL scale in a sample of patients with report of cervical pain: factor analysis, item response theory analysis, and line item validity},
abstract = {BACKGROUND: Few functional outcomes scales have used Item Response Theory (IRT) for validation. IRT allows individual line item validations and offers substantial advantages over classic methods of scale validation or the simplest from of IRT known as Rasch. Rasch analysis reduces data to dichotomous variables thus decreasing the sensitivity of Likert-type data responses. PURPOSE: The purpose of this study was to create an outcome scale associated with the latent trait of functioning and disability, validated using IRT, in a population with report of cervical pain. METHODS: Using the NHANES database, a recently created scale (NHANES ADL scale) was analysed using factor analysis, internal analyses of consistency, IRT, and comparison with internal measures of functioning and disability. RESULTS: The newly created NHANES ADL scale demonstrated uni-dimensionality, was internally reliable, and was correlated to internal measures of functioning and disability. Additionally, the majority of the scale items demonstrate strong discrimination and suitable thresholds. DISCUSSION: The NHANES ADL scale effectively measures physical, social, and emotional disability in patients with a cervical impairment, and may be an efficient measure of perceived limitations from working and generalized daily physical activity. CONCLUSION: The newly created NHANES ADL scale demonstrates internal consistency, unidimensionality, and line item validity. The NHANES ADL scale appears to be a useful instrument in measurement of functioning and disability in patients with report of cervical pain.},

title = {Genotype over-diagnosis in amygdala responsiveness: affective processing in social anxiety disorder},
abstract = {BACKGROUND: Although the amygdala is thought to be a crucial brain region for negative affect, neuroimaging studies do not always show enhanced amygdala response to aversive stimuli in patients with anxiety disorders. Serotonin (5-HT)-related genotypes may contribute to interindividual variability in amygdala responsiveness. The short (s) allele of the 5-HT transporter linked polymorphic region (5-HTTLPR) and the T variant of the G-703T polymorphism in the tryptophan hydroxylase-2 (TPH2) gene have previously been associated with amygdala hyperresponsivity to negative faces in healthy controls. We investigated the influence of these polymorphisms on amygdala responsiveness to angry faces in patients with social anxiety disorder (SAD) compared with healthy controls. METHODS: We used positron emission tomography with oxygen 15-labelled water to assess regional cerebral blood flow in 34 patients with SAD and 18 controls who viewed photographs of angry and neutral faces presented in counterbalanced order. We genotyped all participants with respect to the 5-HTTLPR and TPH2 polymorphisms. RESULTS: Patients with SAD and controls had increased left amygdala activation in response to angry compared with neutral faces. Genotype but not diagnosis explained a significant portion of the variance in amygdala responsiveness, the response being more pronounced in carriers of s and/or T alleles. LIMITATIONS: Our analyses were limited owing to the small sample and the fact that we were unable to match participants on genotype before enrollment. In addition, other imaging techniques not used in our study may have revealed additional effects of emotional stimuli. CONCLUSION: Amygdala responsiveness to angry faces was more strongly related to serotonergic polymorphisms than to diagnosis of SAD. Emotion activation studies comparing amygdala excitability in patient and control groups could benefit from taking variation in 5-HT-related genes into account.},

title = {Efficient Sparse Matrix-Vector Multiplication on CUDA},
abstract = {The massive parallelism of graphics processing units (GPUs) offers tremendous performance in many high-performance computing applications. While dense linear algebra readily maps to such platforms, harnessing this potential for sparse matrix computations presents additional challenges. Given its role in iterative methods for solving sparse linear systems and eigenvalue problems, sparse matrix-vector multiplication (SpMV) is of singular importance in sparse linear algebra.
In this paper we discuss data structures and algorithms for SpMV that are efficiently implemented on the CUDA platform for the fine-grained parallel architecture of the GPU. Given the memory-bound nature of SpMV, we emphasize memory bandwidth efficiency and compact storage formats. We consider a broad spectrum of sparse matrices, from those that are well-structured and regular to highly irregular matrices with large imbalances in the distribution of nonzeros per matrix row. We develop methods to exploit several common forms of matrix structure while offering alternatives which accommodate greater irregularity.
On structured, grid-based matrices we achieve performance of 36 GFLOP/s in single precision and 16 GFLOP/s in double precision on a GeForce GTX 280 GPU. For unstructured finite-element matrices, we observe performance in excess of 15 GFLOP/s and 10 GFLOP/s in single and double precision respectively. These results compare favorably to prior state-of-the-art studies of SpMV methods on conventional multicore processors. Our double precision SpMV performance is generally two and a half times that of a Cell BE with 8 SPEs and more than ten times greater than that of a quad-core Intel Clovertown system.},

title = {Cortical thickness is influenced by regionally specific genetic factors},
abstract = {BACKGROUND: Although global brain structure is highly heritable, there is still variability in the magnitude of genetic influences on the size of specific regions. Yet, little is known about the patterning of those genetic influences, i.e., whether the same genes influence structure throughout the brain or whether there are regionally specific sets of genes. METHODS: We mapped the heritability of cortical thickness throughout the brain using three-dimensional structural magnetic resonance imaging in 404 middle-aged male twins. To assess the amount of genetic overlap between regions, we then mapped genetic correlations between three selected seed points and all other points comprising the continuous cortical surface. RESULTS: There was considerable regional variability in the magnitude of genetic influences on cortical thickness. The primary visual (V1) seed point had strong genetic correlations with posterior sensory and motor areas. The anterior temporal seed point had strong genetic correlations with anterior frontal regions but not with V1. The middle frontal seed point had strong genetic correlations with inferior parietal regions. CONCLUSIONS: These results provide strong evidence of regionally specific patterns rather than a single, global genetic factor. The patterns are largely consistent with a division between primary and association cortex, as well as broadly defined patterns of brain gene expression, neuroanatomical connectivity, and brain maturation trajectories, but no single explanation appears to be sufficient. The patterns do not conform to traditionally defined brain structure boundaries. This approach can serve as a step toward identifying novel phenotypes for genetic association studies of psychiatric disorders and normal and pathological cognitive aging.},

title = {Gene-centric characteristics of genome-wide association studies},
abstract = {BACKGROUND: The high-throughput genotyping chips have contributed greatly to genome-wide association (GWA) studies to identify novel disease susceptibility single nucleotide polymorphisms (SNPs). The high-density chips are designed using two different SNP selection approaches, the direct gene-centric approach, and the indirect quasi-random SNPs or linkage disequilibrium (LD)-based tagSNPs approaches. Although all these approaches can provide high genome coverage and ascertain variants in genes, it is not clear to which extent these approaches could capture the common genic variants. It is also important to characterize and compare the differences between these approaches. METHODOLOGY/PRINCIPAL FINDINGS: In our study, by using both the Phase II HapMap data and the disease variants extracted from OMIM, a gene-centric evaluation was first performed to evaluate the ability of the approaches in capturing the disease variants in Caucasian population. Then the distribution patterns of SNPs were also characterized in genic regions, evolutionarily conserved introns and nongenic regions, ontologies and pathways. The results show that, no mater which SNP selection approach is used, the current high-density SNP chips provide very high coverage in genic regions and can capture most of known common disease variants under HapMap frame. The results also show that the differences between the direct and the indirect approaches are relatively small. Both have similar SNP distribution patterns in these gene-centric characteristics. CONCLUSIONS/SIGNIFICANCE: This study suggests that the indirect approaches not only have the advantage of high coverage but also are useful for studies focusing on various functional SNPs either in genes or in the conserved regions that the direct approach supports. The study and the annotation of characteristics will be helpful for designing and analyzing GWA studies that aim to identify genetic risk factors involved in common diseases, especially variants in genes and conserved regions.},

abstract = {In this paper we propose a new regression interpretation of the Cholesky factor of the covari- ance matrix, as opposed to the well known regression interpretation of the Cholesky factor of the inverse covariance, which leads to a new class of regularized covariance estimators suitable for high-dimensional problems. Regularizing the Cholesky factor of the covariance via this regres- sion interpretation always results in a positive definite estimator. In particular, one can obtain a positive definite banded estimator of the covariance matrix at the same computational cost as the popular banded estimator proposed by Bickel and Levina (2008b), which is not guaranteed to be positive definite. We also establish theoretical connections between banding Cholesky factors of the covariance matrix and its inverse and constrained maximum likelihood estimation under the banding constraint, and compare the numerical performance of several methods in simulations and on a sonar data example.},

abstract = {BACKGROUND: The Montgomery Asberg Depression Rating Scale (MADRS) is a frequently used observer-rated depression scale. In the present study, a telephonic rating was compared with a face-to-face rating in 66 primary care patients with minor or mild-major depression. The aim of the present study was to assess the validity of the administration by telephone. Additional objective was to study the validity of the first item, 'apparent sadness', the only item purely based on observation. METHODS: The present study was a validity study. During an in-person interview at the patient's home a trained interviewer administered the MADRS. A few days later the MADRS was administered again, but now by telephone and by a : Mean total score on the in-person administration was 24.0 (SD = 11.1), and on the telephone administration 23.5 (SD = 10.4). The ICC for the full scale was 0.65. Homogeneity analysis showed that the observation item 'apparent sadness' fitted well into the scale. CONCLUSION: The full MADRS, including the observation item 'apparent sadness', can be administered reliably by telephone.},

title = {Integrating response shift into health-related quality of life research: a theoretical model},
abstract = {Patients confronted with a life-threatening or chronic disease are faced with the necessity to accommodate to their illness. An important mediator of this adaptation process is 'response shift' which involves changing internal standards, values and the conceptualization of quality of life (QOL). Integrating response shift into QOL research would allow a better understanding of how QOL is affected by changes in health status and would direct the development of reliable and valid measures for assessing changes in QOL. A theoretical model is proposed to clarify and predict changes in QOL as a result of the interaction of: (a) a catalyst, referring to changes in the respondent's health status; (b) antecedents, pertaining to stable or dispositional characteristics of the individual (e.g. personality); (c) mechanisms, encompassing behavioral, cognitive, or affective processes to accommodate the changes in health status (e.g. initiating social comparisons, reordering goals); and (d) response shift, defined as changes in the meaning of one's self-evaluation of QOL resulting from changes in internal standards, values, or conceptualization. A dynamic feedback loop aimed at maintaining or improving the perception of QOL is also postulated. This model is illustrated and the underlying assumptions are discussed. Future research directions are outlined that may further the investigation of response shift, by testing specific hypotheses and predictions about the QOL domains and the clinical and psychosocial conditions that would potentiate or prevent response shift effects.},

title = {The Art of Data Augmentation},
abstract = {The term data augmentation refers to methods for constructing iterative optimization or sampling algorithms via the introduction of unobserved data or latent variables. For de- terministic algorithms, the method was popularized in the general statistical community by the seminal article by Dempster, Laird, and Rubin on the EM algorithm for maximizing a likelihood function or, more generally, a posterior density. For stochastic algorithms, the method was popularized in the statistical literature by Tanner and Wong's Data Augmenta- tion algorithm for posterior sampling and in the physics literature by Swendsen and Wang's algorithm for sampling from the Ising and Potts models and their generalizations; in the physics literature, the method of data augmentation is referred to as the method of auxiliary variables. Data augmentation schemes were used by Tanner and Wong to make simulation feasible and simple, while auxiliary variables were adopted by Swendsen and Wang to im- prove the speed of iterative simulation. In general, however, constructing data augmentation schemes that result in both simple and fast algorithms is a matter of art in that successful strategies vary greatly with the (observed-data)models being considered. After an overview ofdataaugmentation/auxiliaryvariablesandsomerecentdevelopmentsinmethodsforcon- structingsuchef􏰯cientdataaugmentationschemes,weintroduceaneffectivesearchstrategy that combines the ideas of marginal augmentation and conditional augmentation, together with a deterministic approximation method for selecting good augmentation schemes.

We provide theoretical and empirical evidence that the resulting algorithms, while requiring similar programming effort, can show dramatic im- provement over the Gibbs samplers commonly used for these models in practice.

There is considerable evidence for the involvement of serotonin in both the learning of these predictions and the inhibitory consequences that ensue, although less for a causal relationship between the two. In the context of a highly simplified model of chains of affectively charged thoughts, we interpret the combined effects of serotonin in terms of pruning a tree of possible decisions, (i.e., eliminating those choices that have low or negative expected outcomes). We show how a drop in behavioral inhibition, putatively resulting from an experimentally or psychiatrically influenced drop in serotonin, could result in unexpectedly large negative prediction errors and a significant aversive shift in reinforcement statistics. We suggest an interpretation of this finding that helps dissolve the apparent contradiction between the fact that inhibition of serotonin reuptake is the first-line treatment of depression, although serotonin itself is most strongly linked with aversive rather than appetitive outcomes and predictions.},

abstract = {BACKGROUND: There is little population-based evidence on ethnic variation in the most common mental disorders (CMD), anxiety and depression. We compared the prevalence of CMD among representative samples of White, Irish, Black Caribbean, Bangladeshi, Indian and Pakistani individuals living in England using a standardized clinical interview. METHOD: Cross-sectional survey of 4281 adults aged 16-74 years living in private households in England. CMD were assessed using the Revised Clinical Interview Schedule (CIS-R), a standardized clinical interview. RESULTS: Ethnic differences in the prevalence of CMD were modest, and some variation with age and sex was noted. Compared to White counterparts, the prevalence of CMD was higher to a statistically significant degree among Irish [adjusted rate ratios (RR) 2.09, 95% CI 1.16-2.95, p = 0.02] and Pakistani (adjusted RR 2.38, 95 % CI 1.25-3.53, p = 0.02) men aged 35-54 years, even after adjusting for differences in socio-economic status. Higher rates of CMD were also observed among Indian and Pakistani women aged 55-74 years, compared to White women of similar age. The prevalence of CMD among Bangladeshi women was lower than among White women, although this was restricted to those not interviewed in English. There were no differences in rates between Black Caribbean and White samples. CONCLUSIONS: Middle-aged Irish and Pakistani men, and older Indian and Pakistani women, had significantly higher rates of CMD than their White counterparts. The very low prevalence of CMD among Bangladeshi women contrasted with high levels of socio-economic deprivation among this group. Further study is needed to explore reasons for this variation.},

title = {Person Fit in Order-Restricted Latent Class Models},
abstract = {Person-fit analysis revolves around fitting an item response theory (IRT) model to respondents' vectors of item scores on a test and drawing statistical inferences about fit or misfit of these vectors. Four person-fit measures were studied in order-restricted latent class models (OR-LCMs). To decide whether the OR-LCM fits an item score vector, a Bayesian framework was adopted and posterior predictive checks were used. First, simulated Type I error rates and detection rates were investigated for the four person-fit measures under varying test and item characteristics. Second, the suitability of the OR-LCM methodology in a nonparametric IRT context was investigated. The result was Type I error rates close to the nominal Type I error rates and detection rates close to the detection rates found in OR-LCMs. This means that the OR-LCM methodology is a suitable alternative for assessing person fit in nonparametric IRT models.},

title = {Shrunken Dissimilarity Measure for Genome-wide SNP Data Classification},
abstract = {Recent development of high-resolution single-nucleotide polymorphism (SNP) arrays allows detailed assessment of genome-wide human genome variations. However, SNP data typi- cally has a large number of SNPs (e.g., 400 thousand SNPs in genome-wide Parkinson disease SNP data) and a few hundred of samples. Conventional classification methods may not be effective when applied to such genome-wide SNP data. In this paper, we propose to develop and use shrunken dis- similarity measure to analyze and select relevant SNPs for classification problems. Examples for HapMap data and Parkinson data are given to demonstrate the effectiveness of the proposed method and illustrate it has the potential to become a useful analysis tool for SNP data sets. In particular, we find some SNPs in chromosome 2 that they contain in some genes which is relevant to Parkinson disease.},

title = {The use of patient reported outcome measures in routine clinical practice: lack of impact or lack of theory?},
abstract = {This paper applies a theory-driven approach to explore why the use of patient-reported outcome (PRO) measures in clinical practice, in particular, health-related quality of life (HRQoL) instruments, has little or no apparent influence on clinical decision making. A theory-driven approach involves combining knowledge of whether and how an intervention works. It is argued that such an approach is currently lacking within the literature evaluating the effectiveness of feeding back HRQoL information to clinicians. The paper identifies a number of mechanisms that might give rise to the expected outcomes that are currently implicit within the design of the intervention and hypotheses specified within the trials evaluating the use of HRQoL measures in clinical practice. It then examines how far current clinical practice matches these mechanisms and in doing so, a number of possible explanations for the lack of impact of HRQoL on clinical decision making are reviewed. The influence of HRQoL information on clinical decision making depends on a large number of factors related to the design of the intervention, patients' and clinicians' desire to discuss HRQoL issues within the consultation and the legitimacy that clinicians give to HRQoL instruments. To date, knowledge of how the feedback of HRQoL information to clinicians might improve doctor-patient communication or clinical decision making has yet to sufficiently inform an assessment of whether these aspects of patient care are improved. The paper concludes by specifying how the feedback of HRQoL information to clinicians might be modified to maximise its impact on clinical decision making.},

abstract = {Many emotional intelligence (EI) scales have been found to overlap with personality scales and it has been argued that EI scales are measuring personality. In the present study it was hypothesised that EI would explain unique variance in life satisfaction beyond that predicted by personality, IQ, and control variables. A community sample (N = 191) aged 18--79 years (M = 35.94, SD = 14.17) was recruited. Because IQ showed no bivariate relationship with life satisfaction, IQ was not used in further analyses. After con- trolling for marital status and income, personality accounted for an additional 34.2% of the variance in life satisfaction, and total EI scores accounted for a further 1.3% (p < 0.05). Further analysis revealed that the additional variance was explained by the EI dimension of Emotional Management. In a competing analy- sis, EI explained 28.3% of the variance at step 2, and personality accounted for a further 8.8% of the var- iance at step 3. It was concluded that EI predicted some unique variance in life satisfaction, and that there was substantial conceptual overlap between EI and personality. However, it is argued that, rather than being redundant, emotional intelligence may offer valuable insights to current conceptions of personality.},

abstract = {Several independent studies and meta-analyses aimed at identifying genomic regions linked to bipolar disorder (BP) have failed to find clear and consistent evidence of linkage regions. Our hypothesis is that combining the original genotype data provides benefits of increased power and control over sources of heterogeneity that outweigh the difficulty and potential pitfalls of the implementation. We conducted a combined analysis using the original genotype data from 11 BP genomewide linkage scans comprising 5,179 individuals from 1,067 families. Heterogeneity among studies was minimized in our analyses by using uniform methods of analysis and a common, standardized marker map and was assessed using novel methods developed for meta-analysis of genome scans. To date, this collaboration is the largest and most comprehensive analysis of linkage samples involving a psychiatric disorder. We demonstrate that combining original genome-scan data is a powerful approach for the elucidation of linkage regions underlying complex disease. Our results establish genomewide significant linkage to BP on chromosomes 6q and 8q, which provides solid information to guide future gene-finding efforts that rely on fine-mapping and association approaches.},

title = {The Sensation Seeking Trait and Substance Use: Research Findings and
Clinical Implications},
abstract = {Sensation seeking (SS) is a personality trait defined by a need to seek novel sensations and experiences, ac- companied by a willingness to take risks for the sake of such experiences. Various measures of SS have been developed and validated, including a scale specifically for children. Among different populations, SS has been associated with the expression of various health-related risk behaviors, most notably substance use and abuse. Evidence from basic research with laboratory animals and from human clinical studies indicates that high sensation seekers may have an overactive mesocorticolimbic dopamine system relative to low sensation seekers. While the precise molecular mechanisms underly- ing SS remain to be elucidated, evidence suggests that low levels of monoamine oxidase activity, as well as altered dopa- mine receptor and dopamine transporter expression and function may play a role. Since altered monoamine function has been implicated in various psychiatric disorders, and since SS has been associated with some of these disorders, clinicians may find that SS offers a useful adjunct in promoting effective patient care and improving patient counseling. This may be especially useful in treating children, adolescents and young adults, as the risk for substance use and abuse is an especially relevant concern during this developmental period.},

Enough of organic behavior is not known to be able to say just how bodily mechanisms do bring about the details of behavior, but it is possible to make rather probable guesses as to what is going on at any given time, and to outline roughly the kind of mechanisms that control activity. The object of this article is to discuss consciousness in the context of behaviorism and to point out that the supposed problem of consciousness does not present insurmountable difficulties to behavioristic treatment. The author of this article concludes that the behaviorist may go his way without fear that his final account will fail of including 'mind' and with the conviction that the inclusion of 'mind' will add nothing to scientific psychology.},

The study sample consisted of 353 participants, the majority of whom were psychiatric patients. Confirmatory factor analysis showed that a one-factor model provided the best fit to the data. All the DSM BPD criteria had moderate or higher item discrimination parameters, indicating that all items contributed meaningful information in assessing BPD. Item information functions revealed that the BPD criteria as a whole were useful for capturing BPD traits in the moderately severe to severe range, but that they performed less well in the less severe range. The general conclusion is that the criteria do represent a coherent syndrome and that further research on the informational value of the individual criteria would be useful.},

abstract = {BACKGROUND: The evaluation of patient-reported outcomes (PROs) in health care has seen greater use in recent years, and methods to improve the reliability and validity of PRO instruments are advancing. This paper discusses the cognitive interviewing procedures employed by the Patient Reported Outcomes Measurement Information System (PROMIS) pediatrics group for the purpose of developing a dynamic, electronic item bank for field testing with children and adolescents using novel computer technology. The primary objective of this study was to conduct cognitive interviews with children and adolescents to gain feedback on items measuring physical functioning, emotional health, social health, fatigue, pain, and asthma-specific symptoms. METHODS: A total of 88 cognitive interviews were conducted with 77 children and adolescents across two sites on 318 items. From this initial item bank, 25 items were deleted and 35 were revised and underwent a second round of cognitive interviews. A total of 293 items were retained for field testing. RESULTS: Children as young as 8 years of age were able to comprehend the majority of items, response options, directions, recall period, and identify problems with language that was difficult for them to understand. Cognitive interviews indicated issues with item comprehension on several items which led to alternative wording for these items. CONCLUSION: Children ages 8-17 years were able to comprehend most item stems and response options in the present study. Field testing with the resulting items and response options is presently being conducted as part of the PROMIS Pediatric Item Bank development process.},

abstract = {Executive function deficits are among the most frequently reported symptoms of autism spectrum disorders (ASDs), however, there have been few functional magnetic resonance imaging (fMRI) studies that investigate the neural substrates of executive function deficits in ASDs, and only one in adolescents. The current study examined cognitive control - the ability to maintain task context online to support adaptive functioning in the face of response competition - in 22 adolescents aged 12-18 with autism spectrum disorders and 23 age, gender, and IQ matched typically developing subjects. During the cue phase of the task, where subjects must maintain information online to overcome a prepotent response tendency, typically developing subjects recruited significantly more anterior frontal (BA 10), parietal (BA 7 and BA 40), and occipital regions (BA 18) for high control trials (25% of trials) versus low control trials (75% of trials). Both groups showed similar activation for low control cues, however the ASD group exhibited significantly less activation for high control cues. Functional connectivity analysis using time series correlation, factor analysis, and beta series correlation methods provided convergent evidence that the ASD group exhibited lower levels of functional connectivity and less network integration between frontal, parietal, and occipital regions. In the typically developing group, fronto-parietal connectivity was related to lower error rates on high control trials. In the autism group, reduced fronto-parietal connectivity was related to attention deficit hyperactivity disorder symptoms.},

abstract = {OBJECTIVE: The objective of this study was to investigate the relationship of biopsychosocial variables to fatigue in patients with chronic hepatitis C (CHC) with the goal of identifying areas of possible intervention. METHOD: Ninety-four patients with CHC not on antiviral therapy completed a demographic questionnaire and measures of fatigue, health-related quality of life, and depression. Fibrosis stage and relevant medical information were obtained from medical records. RESULTS: A stepwise multiple regression analysis revealed that the most significant predictor of fatigue was poor social functioning, followed by poor physical functioning, greater depression, and female gender. Together, these variables accounted for 68% of the total variance in fatigue. DISCUSSION: Study findings suggest that treatment strategies for fatigue in patients with CHC should focus on increasing social functioning in addition to improving physical functioning and decreasing depressive symptoms. Research investigating the effectiveness of interventions targeting social functioning, such as support groups and supportive counseling, is recommended.},

abstract = {This article reviews the results of survey methodological research that illustrate phenomena of potential interest to investigators of memory, and also reviews psychological research designed to explore some of these phenomena under controlled laboratory conditions. We classify the phenomena reviewed into broad categories of remembering what events occurred, remembering when events occurred, and estimation and reconstruction processes used in reporting recurring events. We delineate the contributions of this research for our understanding of memory phenomena and show where this research has revealed gaps in our existing theories and knowledge. These findings present challenges for future collaboration between cognitive psychologists and survey methodologists.},

title = {The Hamilton Depression Rating Scale: has the gold standard become a lead weight?},
abstract = {OBJECTIVE: The Hamilton Depression Rating Scale has been the gold standard for the assessment of depression for more than 40 years. Criticism of the instrument has been increasing. The authors review studies published since the last major review of this instrument in 1979 that explicitly examine the psychometric properties of the Hamilton depression scale. The authors' goal is to determine whether continued use of the Hamilton depression scale as a measure of treatment outcome is justified. METHOD: MEDLINE was searched for studies published since 1979 that examine psychometric properties of the Hamilton depression scale. Seventy studies were identified and selected, and then grouped into three categories on the basis of the major psychometric properties examined-reliability, item-response characteristics, and validity. RESULTS: The Hamilton depression scale's internal reliability is adequate, but many scale items are poor contributors to the measurement of depression severity; others have poor interrater and retest reliability. For many items, the format for response options is not optimal. Content validity is poor; convergent validity and discriminant validity are adequate. The factor structure of the Hamilton depression scale is multidimensional but with poor replication across samples. CONCLUSIONS: Evidence suggests that the Hamilton depression scale is psychometrically and conceptually flawed. The breadth and severity of the problems militate against efforts to revise the current instrument. After more than 40 years, it is time to embrace a new gold standard for assessment of depression.},

title = {Relationship of health-related quality of life to treatment adherence and sustained response in chronic hepatitis C patients},
abstract = {Interferon therapy may exacerbate health-related quality of life (HRQL) deficits associated with hepatitis C virus (HCV) early in the course of therapy. Treatment with polyethylene glycol-modified interferon (peginterferon) alfa-2a (40 kd) provides improved sustained response over interferon alfa-2a, but its effect on HRQL is unknown. The objective of this study was to (1) evaluate the effect of sustained virologic response on HRQL in patients with HCV and (2) determine whether impairment of HRQL during treatment contributes to early treatment discontinuation. Data consisted of a pooled secondary analysis of patients (n = 1,441) across 3 international, multicenter, open-label, randomized studies that compared peginterferon alfa-2a (40 kd) with interferon alfa-2a. ANCOVA was used to examine the effect of sustained virologic response on HRQL. Repeated-measures mixed-models ANCOVA was used to compare Fatigue Severity Scale (FSS) and SF-36 scores during treatment by treatment group. Logistic regression analysis was used to examine the association between changes at baseline in on-treatment HRQL and early treatment discontinuation. Sustained virologic response was associated with marked improvements from baseline to end of follow-up in all subjects, including patients with cirrhosis. During treatment, patients receiving peginterferon alfa-2a (40 kd) had statistically significantly better scores on both the SF-36 and FSS. Baseline
