  2. Cognitive-perceptual deficits and symptom correlates in first-episode schizophrenia

    Directory of Open Access Journals (Sweden)

    Riaan M. Olivier


    Full Text Available Background: Thought disorder and visual-perceptual deficits have been well documented, but their relationships with clinical symptoms and cognitive function remain unclear. Cognitive-perceptual deficits may underscore clinical symptoms in schizophrenia patients. Aim: This study aimed to explore how thought disorder and form perception are related with clinical symptoms and cognitive dysfunction in first-episode schizophrenia. Setting: Forty-two patients with a first-episode of schizophrenia, schizophreniform or schizoaffective disorder were recruited from community clinics and state hospitals in the Cape Town area. Methods: Patients were assessed at baseline with the Rorschach Perceptual Thinking Index (PTI, the Positive and Negative Syndrome Scale (PANSS and the MATRICS Cognitive Consensus Battery (MCCB. Spearman correlational analyses were conducted to investigate relationships between PTI scores, PANSS factor analysis-derived domain scores and MCCB composite and subscale scores. Multiple regression models explored these relationships further. Results: Unexpectedly, poor form perception (X- % was inversely correlated with the severity of PANSS positive symptoms (r = -0.42, p = 0.02. Good form perception (XA% correlated significantly with speed of processing (r = 0.59, p < 0.01, working memory (r = 0.48, p < 0.01 and visual learning (r = 0.55, p < 0.01. PTI measures of thought disorder did not correlate significantly with PANSS symptom scores or cognitive performance. Conclusions: Form perception is associated with positive symptoms and impairment in executive function during acute psychosis. These findings suggest that there may be clinical value in including sensory-perceptual processing tasks in cognitive remediation and social cognitive training programmes for schizophrenia patients.

  4. Association between unsafe driving performance and cognitive-perceptual dysfunction in older drivers. (United States)

    Park, Si-Woon; Choi, Eun Seok; Lim, Mun Hee; Kim, Eun Joo; Hwang, Sung Il; Choi, Kyung-In; Yoo, Hyun-Chul; Lee, Kuem Ju; Jung, Hi-Eun


    To find an association between cognitive-perceptual problems of older drivers and unsafe driving performance during simulated automobile driving in a virtual environment. Cross-sectional study. A driver evaluation clinic in a rehabilitation hospital. Fifty-five drivers aged 65 years or older and 48 drivers in their late twenties to early forties. All participants underwent evaluation of cognitive-perceptual function and driving performance, and the results were compared between older and younger drivers. The association between cognitive-perceptual function and driving performance was analyzed. Cognitive-perceptual function was evaluated with the Cognitive Perceptual Assessment for Driving (CPAD), a computer-based assessment tool consisting of depth perception, sustained attention, divided attention, the Stroop test, the digit span test, field dependency, and trail-making test A and B. Driving performance was evaluated with use of a virtual reality-based driving simulator. During simulated driving, car crashes were recorded, and an occupational therapist observed unsafe performances in controlling speed, braking, steering, vehicle positioning, making lane changes, and making turns. Thirty-five older drivers did not pass the CPAD test, whereas all of the younger drivers passed the test. When using the driving simulator, a significantly greater number of older drivers experienced car crashes and demonstrated unsafe performance in controlling speed, steering, and making lane changes. CPAD results were associated with car crashes, steering, vehicle positioning, and making lane changes. Older drivers who did not pass the CPAD test are 4 times more likely to experience a car crash, 3.5 times more likely to make errors in steering, 2.8 times more likely to make errors in vehicle positioning, and 6.5 times more likely to make errors in lane changes than are drivers who passed the CPAD test. Unsafe driving performance and car crashes during simulated driving were more

  5. Assessing the reliability and validity of the Revised Two Factor Study Process Questionnaire (R-SPQ2F) in Ghanaian medical students. (United States)

    Mogre, Victor; Amalba, Anthony


    We investigated the validity and reliability of the Revised Two Factor Study Process Questionnaire (R-SPQ2F) in preclinical students in Ghana. The R-SPQ2F was administered to 189 preclinical students of the University for Development Studies, School of Medicine and Health Sciences. Both descriptive and inferential statistics with Cronbach's alpha test and factor analysis were done. The mean age of the students was 22.69± 0.18years, 60.8% (n=115) were males and 42.3% (n=80) were in their second year of medical training. The students had higher mean deep approach scores (31.23±7.19) than that of surface approach scores (22.62±6.48). Findings of the R-SPQ2F gave credence to a solution of two-factors indicating deep and surface approaches accounting for 49.80% and 33.57%, respectively, of the variance. The scales of deep approach (Cronbach's alpha, 0.80) and surface approach (Cronbach's alpha, 0.76) and their subscales demonstrated an internal consistency that was good. The factorial validity was comparable to other studies. Our study confirms the construct validity and internal consistency of the R-SPQ2F for measuring approaches to learning in Ghanaian preclinical students. Deep approach was the most dominant learning approach among the students. The questionnaire can be used to measure students' approaches to learning in Ghana and in other African countries.

  6. La "visión del aura" como experiencia alucinatoria en individuos no-clinicos The aura experience as cognitive perceptual schizotypy in non-clinical population

    Alejandro Parra


    spontaneously see the "aura" or energy field of a person, also tend to exhibit elevated levels of imaginative processing or fantasy proneness. There are some indications that those who have a high capacity for absorption usually also experience different parasomatic shapes, tactile hallucinations and sensations of subtle energies, as well as schizotypical ideation, perceptual error and increased synesthesia. The objective is to calculate the correlations of psychological absorption scores, dissociation, fantasy proneness, intensity of imagination and the schizotypical tendency of people who claim to see auras (N=83, in comparison to a group of people lacking these experiences (N=503. The results indicate a higher level of cognitive perceptual schizotypy than for those who do not have this experience. Possibly, these people have a much more intense imaginative life. This does not necessarily have any psychopathological implications for the individual; people who see auras might simply be sensitive to anomalous perceptual experiences.

  7. Examining the cross-cultural sensitivity of the Revised Two-Factor Study Process Questionnaire (R-SPQ-2F and validation of a Dutch version.

    Directory of Open Access Journals (Sweden)

    Ann Stes

    Full Text Available The Revised Two-Factor Study Process Questionnaire (R-SPQ-2F is used to examine students' study approaches in higher education. The questionnaire assumes to measure two factors: a deep and a surface study approach. Analyses into the validity and reliability of the original English R-SPQ-2F yielded positive results. In this study, we examined the degree to which these positive results can also be found for the Dutch version that we developed. By comparing our results with the results of earlier studies in different cultures, we conclude cross-cultural sensitivity is an important point to be borne in mind when using the R-SPQ-2F. Our research supports the validity and reliability of our Dutch version of the R-SPQ-2F.

No sex or year differences were found in the approaches to learning measured with the ASSIST, yet differences were...

  10. Self-reported symptoms of schizotypal and borderline personality disorder in patients with mood disorders. (United States)

    Baryshnikov, I; Suvisaari, J; Aaltonen, K; Koivisto, M; Näätänen, P; Karpov, B; Melartin, T; Oksanen, J; Suominen, K; Heikkinen, M; Paunio, T; Joffe, G; Isometsä, E


    Distinguishing between symptoms of schizotypal (SPD) and borderline personality disorders (BPD) is often difficult due to their partial overlap and frequent co-occurrence. We investigated correlations in self-reported symptoms of SPD and BPD in questionnaires at the levels of both total scores and individual items, examining overlapping dimensions. Two questionnaires, the McLean Screening Instrument (MSI) for BPD and the Schizotypal Personality Questionnaire Brief (SPQ-B) for SPD, were filled in by patients with mood disorders (n=282) from specialized psychiatric care in a study of the Helsinki University Psychiatric Consortium. Correlation coefficients between total scores and individual items of the MSI and SPQ-B were estimated. Multivariate regression analysis (MRA) was conducted to examine the relationships between SPQ-B and MSI. The Spearman's correlation between total scores of the MSI and SPQ-B was strong (rho=0.616, P<0.005). Items of MSI reflecting disrupted relatedness and affective dysregulation correlated moderately (rφ varied between 0.2 and 0.4, P<0.005) with items of SPQ. Items of MSI reflecting behavioural dysregulation correlated only weakly with items of SPQ. In MRA, depressive symptoms, sex and MSI were significant predictors of SPQ-B score, whereas symptoms of anxiety, age and SPQ-B were significant predictors of MSI score. Items reflecting cognitive-perceptual distortions and affective symptoms of BPD appear to overlap with disorganized and cognitive-perceptual symptoms of SPD. Symptoms of depression may aggravate self-reported features of SPQ-B, and symptoms of anxiety features of MSI. Symptoms of behavioural dysregulation of BPD and interpersonal deficits of SPQ appear to be non-overlapping. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  11. The independence of schizotypy from affective temperaments--a combined confirmatory factor analysis of SPQ and the short TEMPS-A. (United States)

    Preti, Antonio; Corrias, Irene; Gabbrielli, Mersia; Lai, Veronica; Muratore, Tamara; Pintus, Elisa; Pintus, Mirra; Sanna, Sara; Scanu, Rosanna; Tronci, Debora; Vellante, Marcello; Siddi, Sara; Petretto, Donatella Rita; Carta, Mauro Giovanni


    Sparse evidence of a co-aggregation of the risk of schizophrenia and bipolar disorder provides support for a shared but nonspecific genetic etiology of bipolar disorder and schizophrenia. Temperaments are conceptualized as trait sub-syndromic conditions of major pathologies. This study set out to test the hypothesis of a continuum between schizotypy and affective temperaments versus the alternative hypothesis of their independence based on a cross-sectional, survey design involving 649 (males: 47%) college students. The short 39-item TEMPS-A and the SPQ were used as measures of the affective temperaments and of schizotypy, respectively. Confirmatory factor analyses were applied to a unidimensional model, to a standard correlate traits model, to second-order representations of a common latent structure, and to a bifactor model. Confirmatory bifactor modeling provided evidence against a complete independence of the dimensions subsumed by the affective and the schizotypal traits. The best solution distinguished between two sub-domains grouping positive symptoms and negative symptoms as measured by the SPQ subscales, and a sub-domain related to the affective temperaments as measured by the TEMPS-A. Limitations due to the use of subscales from two different tools should be taken into account. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  12. Relationship between lifetime suicide attempts and schizotypal traits in patients with schizophrenia. (United States)

    Patients with schizophrenia are at increased risk for suicide. Various risk factors for suicide have been reported in schizophrenia; however, few studies have examined the association between personality traits and suicidal behavior. We administered the Schizotypal Personality Questionnaire (SPQ) to 87 Japanese patients with schizophrenia (49 males; mean age 38.1 ± 10.6 years) with and without a history of suicide attempts (SA and nSA groups, respectively), and 322 controls (158 males; mean age 40.8 ± 13.9 years). As expected, an analysis of covariance (ANCOVA) controlling for age and sex showed that all SPQ indices (total SPQ score and all three factors, i.e., cognitive-perceptual, interpersonal, and disorganized) were significantly higher in patients with schizophrenia (SA+nSA groups), than controls (psuicide attempts, and that the total SPQ score might be useful to assess the risk of suicide attempt in patients with schizophrenia.

  13. Testing measurement invariance of the schizotypal personality questionnaire-brief scores across Spanish and Swiss adolescents.

    Directory of Open Access Journals (Sweden)

    Javier Ortuño-Sierra

    Full Text Available BACKGROUND: Schizotypy is a complex construct intimately related to psychosis. Empirical evidence indicates that participants with high scores on schizotypal self-report are at a heightened risk for the later development of psychotic disorders. Schizotypal experiences represent the behavioural expression of liability for psychotic disorders. Previous factorial studies have shown that schizotypy is a multidimensional construct similar to that found in patients with schizophrenia. Specifically, using the Schizotypal Personality Questionnaire-Brief (SPQ-B, the three-dimensional model has been widely replicated. However, there has been no in-depth investigation of whether the dimensional structure underlying the SPQ-B scores is invariant across countries. METHODS: The main goal of this study was to examine the measurement invariance of the SPQ-B scores across Spanish and Swiss adolescents. The final sample was made up of 261 Spanish participants (51.7% men; M = 16.04 years and 241 Swiss participants (52.3% men; M = 15.94 years. RESULTS: The results indicated that Raine et al.'s three-factor model presented adequate goodness-of-fit indices. Moreover, the results supported the measurement invariance (configural and partial strong invariance of the SPQ-B scores across the two samples. Spanish participants scored higher on Interpersonal dimension than Swiss when latent means were compared. DISCUSSION: The study of measurement equivalence across countries provides preliminary evidence for the Raine et al.'s three-factor model and of the cross-cultural validity of the SPQ-B scores in adolescent population. Future studies should continue to examine the measurement invariance of the schizotypy and psychosis-risk syndromes across cultures.

  14. Revision Vodcast Influence on Assessment Scores and Study Processes in Secondary Physics (United States)

    Marencik, Joseph J.

    A quasi-experimental switching replications design with matched participants was employed to determine the influence of revision vodcasts, or video podcasts, on students' assessment scores and study processes in secondary physics. This study satisfied a need for quantitative results in the area of vodcast influence on students' learning processes. Thirty-eight physics students in an urban Ohio public high school participated in the study. The students in one Physics class were paired with students in another Physics class through the matching characteristics of current student cumulative test score mean and baseline study process as measured by the Study Process Questionnaire (SPQ). Students in both classes were given identical pedagogic treatment and access to traditional revision tools except for the supplemental revision vodcasts given to the experimental group. After students in the experimental group viewed the revision vodcast for a particular topic, the assessment scores of the students in the experimental group were compared to the assessment scores of the control group through the direct-difference, D, test to determine any difference between the assessment score means of each group. The SPQ was given at the beginning of the experiment and after each physics assessment. The direct-difference method was again used to determine any difference between the SPQ deep approach scores of each group. The SPQ was also used to determine any correlative effects between study process and revision vodcast use on students' assessment scores through descriptive statistics and an analysis of variance (ANOVA) test. Analysis indicated that revision vodcast use significantly increased students' assessment scores (p.05). There were no significant correlative effects of revision vodcast use and study processes on students' assessment scores (p>.05). This study offers educators the empirical support to devote the necessary effort, time, and resources into developing successful

  17. Somatosensory processing and schizophrenia liability: proprioception, exteroceptive sensitivity, and graphesthesia performance in the biological relatives of schizophrenia patients. (United States)

    Chang, Bernard P; Lenzenweger, Mark F


    In the present study, the authors examined somatosensory processing in 30 biological relatives of persons with schizophrenia (hereafter called "schizophrenia relatives"), 30 biological relatives of persons with bipolar affective disorder (psychiatric family control subjects), and 30 healthy control subjects with no family history of psychopathology. All 3 groups completed a weight discrimination task, a 2-point discrimination task, and a complex cognitive somatosensory task (i.e., graphesthesia). The schizophrenia relatives performed significantly worse on all 3 somatosensory tasks compared with both the healthy control subjects and the bipolar relatives. The healthy control subjects and psychiatric family control subjects showed no significant differences on any of the somatosensory tasks. Within the weight discrimination and 2-point discrimination tasks, schizophrenia relatives showed group differences on the d' index, the measure of sensitivity, whereas all 3 groups did not differ on lnbeta, the measure of response bias, suggesting a genuine difference in weight and touch sensitivity. The d' value of the weight discrimination task was significantly associated with both the cognitive-perceptual factor and negative symptom factor of the clinical questionnaire (e.g., Schizotypal Personality Questionnaire; SPQ), whereas the 2-point discrimination d' value and graphesthesia scores were significantly associated only with the cognitive-perceptual factor of the SPQ. Implications for the possible relation between somatosensory task performance and schizophrenia liability are discussed. Copyright (c) 2005 APA, all rights reserved.

Furthermore, there were significant differences in the total score and the interpersonal and disorganized factors between the SA and nSA groups (nSASPQ score of 33.5 was the optimal cut-off value to discriminate the SA group from the nSA group (χ(2[1] = 10.6, p = 0.002, odds ratio: 4.7, 95% confidence interval: 1.8-12.1, sensitivity: 0.70, specificity: 0.67. These results suggest that high schizotypy is associated with lifetime suicide attempts, and that the total SPQ score might be useful to assess the risk of suicide attempt in patients with schizophrenia.

  1. Moderating effect of schizotypy on the relationship between smoking and neurocognition. (United States)

    Hori, H; Matsuo, J; Teraishi, T; Sasayama, D; Kawamoto, Y; Kinoshita, Y; Ota, M; Hattori, K; Kunugi, H


    Smoking rates in schizotypic individuals are shown to be elevated, as in patients with schizophrenia, although findings on the association of smoking with different symptomatology of schizotypy have been mixed. Moreover, possible moderating effects of schizotypy on the relationship between smoking and cognition have not been well documented. The Schizotypal Personality Questionnaire (SPQ) and the full version of the Wechsler Memory Scale-Revised (WMS-R) were administered to 501 healthy adults. Subjects were divided into smokers (n=85) and non-smokers (n=416) based on the presence/absence of current smoking. The analysis of covariance (ANCOVA) on the three factor scores as well as the total score of the SPQ, controlling for age and gender, revealed that cognitive-perceptual factor was significantly associated with an increased rate of smoking (P=0.048). The ANCOVA on the WMS-R indices, with smoking group as a fixed factor and age, gender and total SPQ score as covariates, revealed that the schizotypy-by-smoking interaction was significant for attention/working memory (P=0.029). Positive schizotypy may be associated with more smoking. Schizotypy and smoking could interact with each other to negatively affect attention/working memory. Copyright © 2012 Elsevier Masson SAS.

  2. Interaction Effects of Season of Birth and Cytokine Genes on Schizotypal Traits in the General Population

    Directory of Open Access Journals (Sweden)

    Margarita V. Alfimova


    Full Text Available Literature suggests that the effect of winter birth on vulnerability to schizophrenia might be mediated by increased expression of proinflammatory cytokines due to prenatal infection and its inadequate regulation by anti-inflammatory factors. As the response of the immune system depends on genotype, this study assessed the interaction effects of cytokine genes and season of birth (SOB on schizotypy measured with the Schizotypal Personality Questionnaire (SPQ-74. We searched for associations of IL1B rs16944, IL4 rs2243250, and IL-1RN VNTR polymorphisms, SOB, and their interactions with the SPQ-74 total score in a sample of 278 healthy individuals. A significant effect of the IL4 X SOB interaction was found, p=0.007 and η2=0.028. We confirmed this effect using an extended sample of 373 individuals. Homozygotes CC born in winter showed the highest SPQ total score and differed significantly from winter-born T allele carriers, p=0.049. This difference was demonstrated for cognitive-perceptual and disorganized but not interpersonal dimensions. The findings are consistent with the hypothesis that the cytokine genes by SOB interaction can influence variability of schizotypal traits in the general population. The IL4 T allele appeared to have a protective effect against the development of positive and disorganized schizotypal traits in winter-born individuals.

  4. Relationships between dimensional factors of psychopathy and schizotypy

    Directory of Open Access Journals (Sweden)

    Katie Ann Ragsdale


    Full Text Available Existing research has suggested that comorbid psychopathy may explain one trajectory of violent behavior in a subset of individuals with schizophrenia. However, it remains unclear which specific traits and symptoms are responsible for this relationship and whether it is limited to clinical and/or forensic categories, or if it reflects a dimensional relationship found in the general population. Therefore, the aim of this study was to examine differential relationships between specific factors of psychopathy and schizotypy in a nonpsychiatric and nonforensic sample. 212 undergraduate students (50% female completed the Schizotypal Personality Questionnaire (SPQ and the Psychopathic Personality Inventory-Revised (PPI-R. Correlations revealed that the total SPQ score was positively related to the total PPI-R score and the Self-Centered Impulsivity factor, and negatively related to the Fearless Dominance factor. Self-Centered Impulsivity was positively related to all three SPQ factor scores, with the strongest relationship found with the Cognitive-Perceptual factor. In contrast, Fearless Dominance was negatively related to only the Interpersonal and Disorganized factors of the SPQ, with the strongest relationship found with the Interpersonal factor. Findings suggest that the comorbidity of schizotypy and the self-centered impulsivity aspect of psychopathy is not limited to extreme discrete populations, but exists in a more dimensional manner within a nonpsychiatric sample. In addition, it appears that schizotypy is negatively related to the fearless dominance aspect of psychopathy, which appears to be a novel finding. Results provide preliminary findings that may have implications for developing appropriate prediction, assessment, and treatment techniques for violent behavior in schizophrenia-spectrum disorders.

  5. The influence of schizotypal traits on attention under high perceptual load

    Directory of Open Access Journals (Sweden)

    Hanne Stotesbury


    Full Text Available Schizophrenia Spectrum Disorders (SSD are known to be characterised by abnormalities in attentional processes, but there are inconsistencies in the literature that remain unresolved. This article considers whether perceptual resource limitations play a role in moderating attentional abnormalities in SSD. According to perceptual load theory, perceptual resource limitations can lead to attenuated or superior performance on dual-task paradigms depending on whether participants are required to process, or attempt to ignore, secondary stimuli. If SSD is associated with perceptual resource limitations, and if it represents the extreme end of an otherwise normally distributed neuropsychological phenotype, schizotypal traits in the general population should lead to disproportionate performance costs on dual-task paradigms as a function of the perceptual task demands. To test this prediction, schizotypal traits were quantified via the Schizotypal Personality Questionnaire (SPQ in 74 healthy volunteers, who also completed a dual-task signal detection paradigm that required participants to detect central and peripheral stimuli across conditions that varied in the overall number of stimuli presented. The results confirmed decreasing performance as the perceptual load of the task increased. More importantly, significant correlations between SPQ scores and task performance confirmed that increased schizotypal traits, particularly in the cognitive-perceptual domain, are associated with greater performance decrements under increasing perceptual load. These results confirm that attentional difficulties associated with SSD extend sub-clinically into the general population and suggest that cognitive-perceptual schizotypal traits may represent a risk factor for difficulties in the regulation of attention under increasing perceptual load.

    13). Factor analysis resulted in a 3-factor solution that explained 47.7% of the variance. Factor 1 (disorganized; 10 items) included items related to "odd behavior", "odd speech", as well as "social anxiety", one item of "constricted affect" and one item of "ideas of reference". Factor 2 (interpersonal; 7 items) included items related to "no close friends", "constricted affect", and three of the items of "suspiciousness". Factor 3 (cognitive-perceptual; 5 items) included items related to "ideas of reference", "magical thinking", "unusual perceptual experiences" and one item of "suspiciousness". Coefficient α for the three subscales and total scale were respectively 0.81, 0.81, 0.77 and 0.88. We found no differences in total schizotypy and the three dimensions scores according to age and sex. Factor analysis of the French version of the SPQ-B in a Likert format confirmed the three-factor structure of schizotypy. We found a pure cognitive perceptual dimension including the most representative positive features. As expected, "Suspiciousness" subscale is included in both positive and negative dimensions, but mainly in the negative dimension. Surprisingly, "social anxiety" subscale is included in the disorganized dimension in our analysis. The SPQ-B in a Likert format demonstrated good internal reliability for both total and subscales scores. Unlike previous published results, we did not find any influence of age or gender on schizotypal dimensions. Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS.

  9. Syncope diagnostic scores. (United States)

    Sheldon, Robert


    The diagnosis of syncope poses unique challenges. Syncope has multiple etiologies, with most carrying benign prognoses, and a few less common causes carrying a risk of serious morbidity or death. The history at first glance carries few clues. Faced with this many patients are heavily investigated with tests known to be both useless and expensive. For these reasons considerable emphasis has been placed on developing evidence-based and quantitative histories that might distinguish among the main causes of syncope. Quantitative histories were first developed in populations of several hundred patients with definite diagnoses of various losses of consciousness. Their derivation and use mirror those of experienced clinicians. The first score - the Calgary Syncope Seizures Score - discriminates between epileptic convulsions and syncope with a sensitivity and specificity of about 94%. The second score, the Calgary Syncope Score for normal hearts, discriminates between vasovagal syncope and other causes of syncope with a sensitivity and specificity of about 90%. The third score, the Calgary Syncope Score for Structural Heart Disease, diagnoses ventricular tachycardia with 98% sensitivity and 71% specificity. It also accurately predicts serious arrhythmic outcomes and all cause death. Gaps in the accuracy of the second score have been identified and are being addressed. These scores are proving useful in the clinic, and as entry criteria for observation studies, genetic studies, and randomized clinical trials. A very simple score predicts vasovagal syncope recurrences, based on the number of faints in the preceding year. Work from several centres indicates that scores will distinguish among competing causes of syncope in select populations, such as those with bifascicular heart block, Brugada syndrome, and Long QT syndrome.

  17. Automated Essay Scoring

    Directory of Open Access Journals (Sweden)

    Semire DIKLI


    Full Text Available Automated Essay Scoring Semire DIKLI Florida State University Tallahassee, FL, USA ABSTRACT The impacts of computers on writing have been widely studied for three decades. Even basic computers functions, i.e. word processing, have been of great assistance to writers in modifying their essays. The research on Automated Essay Scoring (AES has revealed that computers have the capacity to function as a more effective cognitive tool (Attali, 2004. AES is defined as the computer technology that evaluates and scores the written prose (Shermis & Barrera, 2002; Shermis & Burstein, 2003; Shermis, Raymat, & Barrera, 2003. Revision and feedback are essential aspects of the writing process. Students need to receive feedback in order to increase their writing quality. However, responding to student papers can be a burden for teachers. Particularly if they have large number of students and if they assign frequent writing assignments, providing individual feedback to student essays might be quite time consuming. AES systems can be very useful because they can provide the student with a score as well as feedback within seconds (Page, 2003. Four types of AES systems, which are widely used by testing companies, universities, and public schools: Project Essay Grader (PEG, Intelligent Essay Assessor (IEA, E-rater, and IntelliMetric. AES is a developing technology. Many AES systems are used to overcome time, cost, and generalizability issues in writing assessment. The accuracy and reliability of these systems have been proven to be high. The search for excellence in machine scoring of essays is continuing and numerous studies are being conducted to improve the effectiveness of the AES systems.

  18. Neuropsychological effects associated with recreational cocaine use. (United States)

    Soar, Kirstie; Mason, Colette; Potton, Anita; Dawkins, Lynne


    Recent evidence suggests that recreational cocaine use is on the increase, with the UK reporting one of the highest levels of use in the EU (EMCDDA 2010). Nevertheless, very few studies have addressed the neuropsychological effects associated with non-dependent recreational cocaine use. The current study aimed to assess whether recreational cocaine users show neuropsychological deficits on a battery of tests, previously shown to be sensitive to cocaine-dependent and psychosis-prone individuals. Schizotypal traits were also measured. Recreational cocaine users (n = 17) were compared with controls (n = 24) on drug use patterns, the General Health Questionnaire, the Brief Schizotypal Personality Questionnaire (SPQ-B) and four neuropsychological tasks: spatial working memory, intra/extra-dimensional set shifting, the Stocking of Cambridge and the rapid visual processing. Relative to controls, recreational cocaine users produced significantly more errors on the intra/extra-dimensional set shift task and completed fewer stages, made significantly more six box stage errors on the spatial working memory task, and made significantly more errors and fewer hits, with overall poorer detection rates on the rapid visual processing task. Recreational cocaine users reported significantly higher scores on the cognitive perceptual and disorganised thinking SPQ-B subscales and total SPQ-B scores compared to controls. Recreational cocaine users displayed impairments on tasks tapping sustained attention, attentional shifting and spatial memory and reported higher schizotypal trait expression. These findings are consistent with the emerging literature suggesting subtle cognitive deficits, putatively reflecting underlying dopaminergic dysfunction, in non-dependent, recreational cocaine users.

  19. Visually scoring hirsutism. (United States)

    Yildiz, Bulent O; Bolour, Sheila; Woods, Keslie; Moore, April; Azziz, Ricardo


    Hirsutism is the presence of excess body or facial terminal (coarse) hair growth in females in a male-like pattern, affects 5-15% of women, and is an important sign of underlying androgen excess. Different methods are available for the assessment of hair growth in women. We conducted a literature search and analyzed the published studies that reported methods for the assessment of hair growth. We review the basic physiology of hair growth, the development of methods for visually quantifying hair growth, the comparison of these methods with objective measurements of hair growth, how hirsutism may be defined using a visual scoring method, the influence of race and ethnicity on hirsutism, and the impact of hirsutism in diagnosing androgen excess and polycystic ovary syndrome. Objective methods for the assessment of hair growth including photographic evaluations and microscopic measurements are available but these techniques have limitations for clinical use, including a significant degree of complexity and a high cost. Alternatively, methods for visually scoring or quantifying the amount of terminal body and facial hair growth have been in use since the early 1920s; these methods are semi-quantitative at best and subject to significant inter-observer variability. The most common visual method of scoring the extent of body and facial terminal hair growth in use today is based on a modification of the method originally described by Ferriman and Gallwey in 1961 (i.e. the mFG method). Overall, the mFG scoring method is a useful visual instrument for assessing excess terminal hair growth, and the presence of hirsutism, in women.

  1. Maxillofacial trauma scoring systems. (United States)

    Sahni, Vaibhav


    The changing complexity of maxillofacial fractures in recent years has created a situation where classical systems of classification of maxillofacial injuries fall short of defining trauma particularly that observed with high-velocity collisions where more than one region of the maxillofacial skeleton is affected. Trauma scoring systems designed specifically for the maxillofacial region are aimed to provide a more accurate assessment of the injury, its prognosis, the possible treatment outcomes, economics, length of hospital stay, and triage. The evolution and logic of such systems along with their merits and demerits are discussed. The author also proposes a new system to aid users in quickly and methodically choosing the system best suited to their needs without having to study a plethora of literature available in order to isolate their choice.

  2. Credit Scoring Modeling

    Directory of Open Access Journals (Sweden)

    Siana Halim


    Full Text Available It is generally easier to predict defaults accurately if a large data set (including defaults is available for estimating the prediction model. This puts not only small banks, which tend to have smaller data sets, at disadvantage. It can also pose a problem for large banks that began to collect their own historical data only recently, or banks that recently introduced a new rating system. We used a Bayesian methodology that enables banks with small data sets to improve their default probability. Another advantage of the Bayesian method is that it provides a natural way for dealing with structural differences between a bank’s internal data and additional, external data. In practice, the true scoring function may differ across the data sets, the small internal data set may contain information that is missing in the larger external data set, or the variables in the two data sets are not exactly the same but related. Bayesian method can handle such kind of problem.

  4. Differences of wells scores accuracy, caprini scores and padua scores in deep vein thrombosis diagnosis (United States)

    Gatot, D.; Mardia, A. I.


    Deep Vein Thrombosis (DVT) is the venous thrombus in lower limbs. Diagnosis is by using venography or ultrasound compression. However, these examinations are not available yet in some health facilities. Therefore many scoring systems are developed for the diagnosis of DVT. The scoring method is practical and safe to use in addition to efficacy, and effectiveness in terms of treatment and costs. The existing scoring systems are wells, caprini and padua score. There have been many studies comparing the accuracy of this score but not in Medan. Therefore, we are interested in comparative research of wells, capriniand padua score in Medan.An observational, analytical, case-control study was conducted to perform diagnostic tests on the wells, caprini and padua score to predict the risk of DVT. The study was at H. Adam Malik Hospital in Medan.From a total of 72 subjects, 39 people (54.2%) are men and the mean age are 53.14 years. Wells score, caprini score and padua score has a sensitivity of 80.6%; 61.1%, 50% respectively; specificity of 80.65; 66.7%; 75% respectively, and accuracy of 87.5%; 64.3%; 65.7% respectively.Wells score has better sensitivity, specificity and accuracy than caprini and padua score in diagnosing DVT.

  5. Playing Music for a Smarter Ear: Cognitive, Perceptual and Neurobiological Evidence (United States)

    Strait, Dana; Kraus, Nina


    Human hearing depends on a combination of cognitive and sensory processes that function by means of an interactive circuitry of bottom-up and top-down neural pathways, extending from the cochlea to the cortex and back again. Given that similar neural pathways are recruited to process sounds related to both music and language, it is not surprising that the auditory expertise gained over years of consistent music practice fine-tunes the human auditory system in a comprehensive fashion, strengthening neurobiological and cognitive underpinnings of both music and speech processing. In this review we argue not only that common neural mechanisms for speech and music exist, but that experience in music leads to enhancements in sensory and cognitive contributors to speech processing. Of specific interest is the potential for music training to bolster neural mechanisms that undergird language-related skills, such as reading and hearing speech in background noise, which are critical to academic progress, emotional health, and vocational success.

  8. D-score: a search engine independent MD-score. (United States)

    Vaudel, Marc; Breiter, Daniela; Beck, Florian; Rahnenführer, Jörg; Martens, Lennart; Zahedi, René P


    While peptides carrying PTMs are routinely identified in gel-free MS, the localization of the PTMs onto the peptide sequences remains challenging. Search engine scores of secondary peptide matches have been used in different approaches in order to infer the quality of site inference, by penalizing the localization whenever the search engine similarly scored two candidate peptides with different site assignments. In the present work, we show how the estimation of posterior error probabilities for peptide candidates allows the estimation of a PTM score called the D-score, for multiple search engine studies. We demonstrate the applicability of this score to three popular search engines: Mascot, OMSSA, and X!Tandem, and evaluate its performance using an already published high resolution data set of synthetic phosphopeptides. For those peptides with phosphorylation site inference uncertainty, the number of spectrum matches with correctly localized phosphorylation increased by up to 25.7% when compared to using Mascot alone, although the actual increase depended on the fragmentation method used. Since this method relies only on search engine scores, it can be readily applied to the scoring of the localization of virtually any modification at no additional experimental or in silico cost. © 2013 WILEY-VCH Verlag GmbH & Co.

    de Mendonça, Vitor Rosa Ramos; Andrade, Bruno Bezerril; Almeida, Alessandro; Barral-Netto, Manoel


    Basic courses in most medical schools assess students' performance by conferring scores. The objective of this work is to use a large score databank for the early identification of students with low performance and to identify course trends based on the mean of students' grades. We studied scores from 2,398 medical students registered in courses over a period of 10 years. Students in the first semester were grouped into those whose ratings remained in the lower quartile in two or more courses (low-performance) and students who had up to one course in the lower quartile (high-performance). ROC curves were built, aimed at the identification of a cut-off average score in the first semesters that would be able to predict low performances in future semesters. Moreover, to follow the long-term pattern of each course, the mean of all scores conferred in a semester was compared to the overall course mean obtained by averaging 10 years of data. Individuals in the low-performance group had a higher risk of being in the lower quartile of at least one course in the second semester (relative risk 3.907; 95% CI: 3.378-4.519) and in the eighth semester (relative risk 2.873; 95% CI: 2.495-3.308). The prediction analysis revealed that an average score of 7.188 in the first semester could identify students that presented scores below the lower quartiles in both the second and eighth semesters (pstudents with low performance may be useful in promoting pedagogical strategies for these individuals. Evaluation of the time trend of scores conferred by courses may help departments monitoring changes in personnel and methodology that may affect a student's performance.

  19. Genetic effect on apgar score

    Directory of Open Access Journals (Sweden)

    Carla Franchi-Pinto


    Full Text Available Intraclass correlation coefficients for one- and five-min Apgar scores of 604 twin pairs born at a southeastern Brazilian hospital were calculated, after adjusting these scores for gestational age and sex. The data support a genetic hypothesis only for 1-min Apgar score, probably because it is less affected by the environment than 4 min later, after the newborns have been under the care of a neonatology team. First-born twins exhibited, on average, better clinical conditions than second-born twins. The former showed a significantly lower proportion of Apgar scores under seven than second-born twins, both at 1 min (17.5% vs. 29.8% and at 5 min (7.2% vs. 11.9%. The proportion of children born with "good" Apgar scores was significantly smaller among twins than among 1,522 singletons born at the same hospital. Among the latter, 1- and 5-min Apgar scores under seven were exhibited by 9.2% and 3.4% newborns, respectively.Os coeficientes de correlação intraclasse foram calculados para os índices de Apgar 1 e 5 minutos após o nascimento de 604 pares de gêmeos em uma maternidade do sudeste brasileiro, depois que esses índices foram ajustados para idade gestacional e sexo. Os dados obtidos apoiaram a hipótese genética apenas em relação ao primeiro índice de Apgar, provavelmente porque ele é menos influenciado pelo ambiente do que 4 minutos depois, quando os recém-nascidos já estiveram sob os cuidados de uma equipe de neonatologistas. Os gêmeos nascidos em primeiro lugar apresentaram, em média, melhor estado clínico que os nascidos em segundo lugar, visto que os primeiros mostraram uma proporção de índices de Apgar inferiores a 7 significativamente menor do que os nascidos em segundo lugar, tanto um minuto (17,5% contra 29,8% quanto cinco minutos após o nascimento (7,2% contra 11,9%.

  1. Interpreting force concept inventory scores: Normalized gain and SAT scores

    Directory of Open Access Journals (Sweden)

    Jeffrey J. Steinert


    Full Text Available Preinstruction SAT scores and normalized gains (G on the force concept inventory (FCI were examined for individual students in interactive engagement (IE courses in introductory mechanics at one high school (N=335 and one university (N=292 , and strong, positive correlations were found for both populations ( r=0.57 and r=0.46 , respectively. These correlations are likely due to the importance of cognitive skills and abstract reasoning in learning physics. The larger correlation coefficient for the high school population may be a result of the much shorter time interval between taking the SAT and studying mechanics, because the SAT may provide a more current measure of abilities when high school students begin the study of mechanics than it does for college students, who begin mechanics years after the test is taken. In prior research a strong correlation between FCI G and scores on Lawson’s Classroom Test of Scientific Reasoning for students from the same two schools was observed. Our results suggest that, when interpreting class average normalized FCI gains and comparing different classes, it is important to take into account the variation of students’ cognitive skills, as measured either by the SAT or by Lawson’s test. While Lawson’s test is not commonly given to students in most introductory mechanics courses, SAT scores provide a readily available alternative means of taking account of students’ reasoning abilities. Knowing the students’ cognitive level before instruction also allows one to alter instruction or to use an intervention designed to improve students’ cognitive level.

  4. Interval Coded Scoring: a toolbox for interpretable scoring systems

    Directory of Open Access Journals (Sweden)

    Lieven Billiet


    Full Text Available Over the last decades, clinical decision support systems have been gaining importance. They help clinicians to make effective use of the overload of available information to obtain correct diagnoses and appropriate treatments. However, their power often comes at the cost of a black box model which cannot be interpreted easily. This interpretability is of paramount importance in a medical setting with regard to trust and (legal responsibility. In contrast, existing medical scoring systems are easy to understand and use, but they are often a simplified rule-of-thumb summary of previous medical experience rather than a well-founded system based on available data. Interval Coded Scoring (ICS connects these two approaches, exploiting the power of sparse optimization to derive scoring systems from training data. The presented toolbox interface makes this theory easily applicable to both small and large datasets. It contains two possible problem formulations based on linear programming or elastic net. Both allow to construct a model for a binary classification problem and establish risk profiles that can be used for future diagnosis. All of this requires only a few lines of code. ICS differs from standard machine learning through its model consisting of interpretable main effects and interactions. Furthermore, insertion of expert knowledge is possible because the training can be semi-automatic. This allows end users to make a trade-off between complexity and performance based on cross-validation results and expert knowledge. Additionally, the toolbox offers an accessible way to assess classification performance via accuracy and the ROC curve, whereas the calibration of the risk profile can be evaluated via a calibration curve. Finally, the colour-coded model visualization has particular appeal if one wants to apply ICS manually on new observations, as well as for validation by experts in the specific application domains. The validity and applicability

  11. PRSice: Polygenic Risk Score software. (United States)

    Euesden, Jack; Lewis, Cathryn M; O'Reilly, Paul F


    A polygenic risk score (PRS) is a sum of trait-associated alleles across many genetic loci, typically weighted by effect sizes estimated from a genome-wide association study. The application of PRS has grown in recent years as their utility for detecting shared genetic aetiology among traits has become appreciated; PRS can also be used to establish the presence of a genetic signal in underpowered studies, to infer the genetic architecture of a trait, for screening in clinical trials, and can act as a biomarker for a phenotype. Here we present the first dedicated PRS software, PRSice ('precise'), for calculating, applying, evaluating and plotting the results of PRS. PRSice can calculate PRS at a large number of thresholds ("high resolution") to provide the best-fit PRS, as well as provide results calculated at broad P-value thresholds, can thin Single Nucleotide Polymorphisms (SNPs) according to linkage disequilibrium and P-value or use all SNPs, handles genotyped and imputed data, can calculate and incorporate ancestry-informative variables, and can apply PRS across multiple traits in a single run. We exemplify the use of PRSice via application to data on schizophrenia, major depressive disorder and smoking, illustrate the importance of identifying the best-fit PRS and estimate a P-value significance threshold for high-resolution PRS studies. PRSice is written in R, including wrappers for bash data management scripts and PLINK-1.9 to minimize computational time. PRSice runs as a command-line program with a variety of user-options, and is freely available for download from or Supplementary data are available at Bioinformatics online. © The Author 2014.

  15. An Objective Fluctuation Score for Parkinson's Disease (United States)

    Horne, Malcolm K.; McGregor, Sarah; Bergquist, Filip


    Introduction Establishing the presence and severity of fluctuations is important in managing Parkinson’s Disease yet there is no reliable, objective means of doing this. In this study we have evaluated a Fluctuation Score derived from variations in dyskinesia and bradykinesia scores produced by an accelerometry based system. Methods The Fluctuation Score was produced by summing the interquartile range of bradykinesia scores and dyskinesia scores produced every 2 minutes between 0900-1800 for at least 6 days by the accelerometry based system and expressing it as an algorithm. Results This Score could distinguish between fluctuating and non-fluctuating patients with high sensitivity and selectivity and was significant lower following activation of deep brain stimulators. The scores following deep brain stimulation lay in a band just above the score separating fluctuators from non-fluctuators, suggesting a range representing adequate motor control. When compared with control subjects the score of newly diagnosed patients show a loss of fluctuation with onset of PD. The score was calculated in subjects whose duration of disease was known and this showed that newly diagnosed patients soon develop higher scores which either fall under or within the range representing adequate motor control or instead go on to develop more severe fluctuations. Conclusion The Fluctuation Score described here promises to be a useful tool for identifying patients whose fluctuations are progressing and may require therapeutic changes. It also shows promise as a useful research tool. Further studies are required to more accurately identify therapeutic targets and ranges. PMID:25928634

  1. Combination of scoring schemes for protein docking

    Directory of Open Access Journals (Sweden)

    Schomburg Dietmar


    Full Text Available Abstract Background Docking algorithms are developed to predict in which orientation two proteins are likely to bind under natural conditions. The currently used methods usually consist of a sampling step followed by a scoring step. We developed a weighted geometric correlation based on optimised atom specific weighting factors and combined them with our previously published amino acid specific scoring and with a comprehensive SVM-based scoring function. Results The scoring with the atom specific weighting factors yields better results than the amino acid specific scoring. In combination with SVM-based scoring functions the percentage of complexes for which a near native structure can be predicted within the top 100 ranks increased from 14% with the geometric scoring to 54% with the combination of all scoring functions. Especially for the enzyme-inhibitor complexes the results of the ranking are excellent. For half of these complexes a near-native structure can be predicted within the first 10 proposed structures and for more than 86% of all enzyme-inhibitor complexes within the first 50 predicted structures. Conclusion We were able to develop a combination of different scoring schemes which considers a series of previously described and some new scoring criteria yielding a remarkable improvement of prediction quality.

    Mehra, A; Baker, D; Disney, S; Pynsent, P B


    Low back pain effects up to 80% of the population at some time during their active life. Questionnaires are available to help measure pain and disability. The Oswestry Disability Index (ODI) is the most commonly used outcome measure for low back pain. The aim of this study was to see if training in completing the ODI forms improved the scoring accuracy. The last 100 ODI forms completed in a hospital's spinal clinic were reviewed retrospectively and errors in the scoring were identified. Staff members involved in scoring the questionnaire were made aware of the errors and the correct method of scoring explained. A chart was created with all possible scores to aid the staff with scoring. A prospective audit on 50 questionnaires was subsequently performed. The retrospective study showed that 33 of the 100 forms had been incorrectly scored. All questionnaires where one or more sections were not completed by the patient were incorrectly scored. A scoring chart was developed and staff training was implemented. This reduced the error rate to 14% in the prospective audit. Clinicians applying outcome measures should read the appropriate literature to ensure they understand the scoring system. Staff must then be given adequate training in the application of the questionnaires.

  3. Forecasting the value of credit scoring (United States)

    Saad, Shakila; Ahmad, Noryati; Jaffar, Maheran Mohd


    Nowadays, credit scoring system plays an important role in banking sector. This process is important in assessing the creditworthiness of customers requesting credit from banks or other financial institutions. Usually, the credit scoring is used when customers send the application for credit facilities. Based on the score from credit scoring, bank will be able to segregate the "good" clients from "bad" clients. However, in most cases the score is useful at that specific time only and cannot be used to forecast the credit worthiness of the same applicant after that. Hence, bank will not know if "good" clients will always be good all the time or "bad" clients may become "good" clients after certain time. To fill up the gap, this study proposes an equation to forecast the credit scoring of the potential borrowers at a certain time by using the historical score related to the assumption. The Mean Absolute Percentage Error (MAPE) is used to measure the accuracy of the forecast scoring. Result shows the forecast scoring is highly accurate as compared to actual credit scoring.

  4. The Mystery of the Z-Score. (United States)

    Curtis, Alexander E; Smith, Tanya A; Ziganshin, Bulat A; Elefteriades, John A


    Reliable methods for measuring the thoracic aorta are critical for determining treatment strategies in aneurysmal disease. Z-scores are a pragmatic alternative to raw diameter sizes commonly used in adult medicine. They are particularly valuable in the pediatric population, who undergo rapid changes in physical development. The advantage of the Z-score is its inclusion of body surface area (BSA) in determining whether an aorta is within normal size limits. Therefore, Z-scores allow us to determine whether true pathology exists, which can be challenging in growing children. In addition, Z-scores allow for thoughtful interpretation of aortic size in different genders, ethnicities, and geographical regions. Despite the advantages of using Z-scores, there are limitations. These include intra- and inter-observer bias, measurement error, and variations between alternative Z-score nomograms and BSA equations. Furthermore, it is unclear how Z-scores change in the normal population over time, which is essential when interpreting serial values. Guidelines for measuring aortic parameters have been developed by the American Society of Echocardiography Pediatric and Congenital Heart Disease Council, which may reduce measurement bias when calculating Z-scores for the aortic root. In addition, web-based Z-score calculators have been developed to aid in efficient Z-score calculations. Despite these advances, clinicians must be mindful of the limitations of Z-scores, especially when used to demonstrate beneficial treatment effect. This review looks to unravel the mystery of the Z-score, with a focus on the thoracic aorta. Here, we will discuss how Z-scores are calculated and the limitations of their use.

    Acute asthmatic attack in children commonly occurs despite the introduction of effective controllers such as inhaled corticosteroids and leukotriene modifiers. Treatment of acute asthmatic attack requires proper evaluation of attack severity and appropriate selection of medical therapy. In children, measurement of lung function is difficult during acute attack and thus clinical asthma scoring may aid physician in making further decision regarding treatment and admission. We enrolled 70 children with acute asthmatic attack with age range from 1 to 12 years (mean ± SD = 51.5 ± 31.8 months) into the study. Twelve selected asthma severity items were assessed by 2 independent observers prior to administration of salbutamol nebulization (up to 3 doses at 20 minutes interval). Decision for further therapy and admission was made by emergency department physician. Three different scoring systems were constructed from items with best validity. Sensitivity, specificity and accuracy of these scores were assessed. Inter-rater reliability was assessed for each score. Review of previous scoring systems was also conducted and reported. Three severity items had poor validity, i.e., cyanosis, depressed cerebral function, and I:E ratio (p > 0.05). Three items had poor inter-rater reliability, i.e., breath sound quality, air entry, and I:E ratio. These items were omitted and three new clinical scores were constructed from the remaining items. Clinical scoring system comprised retractions, dyspnea, O2 saturation, respiratory rate and wheezing (rangeof score 0-10) gave the best accuracy and inter-rater variability and were chosen for clinical use-Siriraj Clinical Asthma Score (SCAS). A Clinical Asthma Score that is simple, relatively easy to administer and with good validity and variability is essential for treatment of acute asthma in children. Several good candidate scores have been introduced in the past. We described the development of the Siriraj Clinical Asthma Score (SCAS) in

  6. Comparative study of four maxillofacial trauma scoring systems and expert score. (United States)

    Chen, Chen; Zhang, Yi; An, Jin-gang; He, Yang; Gong, Xi


    To select a scoring system suitable for the scoring of maxillofacial trauma by comparing 4 commonly used scoring systems according to expert scoring. Twenty-eight subjects who had experienced maxillofacial trauma constituted the study cohort. Four commonly used systems were selected: New Injury Severity Score (NISS), Facial Injury Severity Scale (FISS), Maxillofacial Injury Severity Score (MFISS), and Maxillofacial Injury Severity Score (MISS). Each patient was graded using these 4 systems. From the experience of our trauma center, an expert scoring table was created. After the purpose and scheme of the study had been explained, 35 experts in maxillofacial surgery were invited to grade the injury of the 28 patients using the expert scoring table according to their clinical experience. The results of the 4 scoring systems and expert score were compared. The results of the 4 scoring systems and expert score demonstrated a normal distribution. All results demonstrated significant differences (P expert score was the greatest (0.801). The correlation coefficient between the NISS, FISS, and MISS and the expert score was 0.714, 0.699, and 0.729, respectively. Agreement between the standardized scores and the expert score was evaluated using Bland-Altman plots; the agreement between the standardized MFISS and expert score was the best. Compared with the other 3 scoring systems, the correlation and agreement between the MFISS and expert score was greater. This finding suggests that the MFISS is more suitable for scoring maxillofacial injuries. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

    Strauss, Michael B; Moon, Hojin; Busch, Jeremy A; Jones, Christopher K; Nhan, Lisa; Miller, Stuart; Le, Phi-Nga Jeannie


    The authors describe an innovative wound score and demonstrate its versatility for scoring a variety of wound types in addition to diabetic foot ulcers (DFUs). To further test its merits, they determined its interobserver reliability in a prospective series of patients. The Wound Score system the authors created integrates the most important features of 4 predominantly used wound scoring systems. It utilizes a logical 0 to 10 format based on 5 assessments each graded from 2 (best) to 0 (worst). The versatility and reliability of the Wound Score were studied in a prospective series of 94 patients with lower extremity wounds. The Wound Score was quick to determine, applicable to a variety of wound types and locations, and highly objective for grading the severity of each of the 5 assessments. The Wound Score categorized wound types as "healthy," "problem," or "futile" for evaluation and management. Diabetes was present in 75.9%, with 70% of the DFUs scoring in the "problem" wound range. Interobserver reli- ability was high (r = 0.81). The objectivity, versatility, and reliability of the Wound Score system facilitates making decisions about the management of wounds, whether DFUs or not, and provides quantification for compara- tive effectiveness research for wound management.

  20. Bayesian Model Averaging for Propensity Score Analysis. (United States)

    Kaplan, David; Chen, Jianshen


    This article considers Bayesian model averaging as a means of addressing uncertainty in the selection of variables in the propensity score equation. We investigate an approximate Bayesian model averaging approach based on the model-averaged propensity score estimates produced by the R package BMA but that ignores uncertainty in the propensity score. We also provide a fully Bayesian model averaging approach via Markov chain Monte Carlo sampling (MCMC) to account for uncertainty in both parameters and models. A detailed study of our approach examines the differences in the causal estimate when incorporating noninformative versus informative priors in the model averaging stage. We examine these approaches under common methods of propensity score implementation. In addition, we evaluate the impact of changing the size of Occam's window used to narrow down the range of possible models. We also assess the predictive performance of both Bayesian model averaging propensity score approaches and compare it with the case without Bayesian model averaging. Overall, results show that both Bayesian model averaging propensity score approaches recover the treatment effect estimates well and generally provide larger uncertainty estimates, as expected. Both Bayesian model averaging approaches offer slightly better prediction of the propensity score compared with the Bayesian approach with a single propensity score equation. Covariate balance checks for the case study show that both Bayesian model averaging approaches offer good balance. The fully Bayesian model averaging approach also provides posterior probability intervals of the balance indices.

    Full Text Available In this paper a family of scoring systems for tennis doubles for testing the hypothesis that pair A is better than pair B versus the alternative hypothesis that pair B is better than A, is established. This family or benchmark of scoring systems can be used as a benchmark against which the efficiency of any doubles scoring system can be assessed. Thus, the formula for the efficiency of any doubles scoring system is derived. As in tennis singles, one scoring system based on the play-the-loser structure is shown to be more efficient than the benchmark systems. An expression for the relative efficiency of two doubles scoring systems is derived. Thus, the relative efficiency of the various scoring systems presently used in doubles can be assessed. The methods of this paper can be extended to a match between two teams of 2, 4, 8, …doubles pairs, so that it is possible to establish a measure for the relative efficiency of the various systems used for tennis contests between teams of players.

  5. The quantile score and its decomposition (United States)

    Bentzien, Sabrina; Friederichs, Petra


    Forecast verification for probabilistic weather and climate predictions gain more and more importance due to the increasing number of ensemble prediction systems. The predictive performance of probabilistic forecasts is generally assessed using proper score functions, which are applied to a set of forecast-observation pairs. The propriety of a score guarantees honesty and prevents hedging. A variety of proper scores exist for different types of probabilistic forecasts. Moreover, proper scoring functions can be decomposed into the three parts reliability, resolution, and uncertainty, which describe main characteristics of a forecasting scheme. This decomposition is well known for the Brier score and the continuous ranked probability score. This study expands the pool of verification methods for probabilistic forecasts by a decomposition of the quantile score (QS). Quantiles are suitable probabilistic measures especially for extreme forecast events, since they do not depend on an apriori defined threshold. The QS is a weighted absolute error between quantile forecasts and observations. We derive a decomposition of the QS in reliability, resolution, and uncertainty, and give a brief description of potential biases. A quantile reliability plot is presented. The quantile verification within this framework is illustrated on precipitation forecasts derived from the mesoscale ensemble prediction system COSMO-DE-EPS of the German Meteorological Service.

  6. A comparison between modified Alvarado score and RIPASA score in the diagnosis of acute appendicitis. (United States)

    Singla, Anand; Singla, Satpaul; Singh, Mohinder; Singla, Deeksha


    Acute appendicitis is a common but elusive surgical condition and remains a diagnostic dilemma. It has many clinical mimickers and diagnosis is primarily made on clinical grounds, leading to the evolution of clinical scoring systems for pin pointing the right diagnosis. The modified Alvarado and RIPASA scoring systems are two important scoring systems, for diagnosis of acute appendicitis. We prospectively compared the two scoring systems for diagnosing acute appendicitis in 50 patients presenting with right iliac fossa pain. The RIPASA score correctly classified 88 % of patients with histologically confirmed acute appendicitis compared with 48.0 % with modified Alvarado score, indicating that RIPASA score is more superior to Modified Alvarado score in our clinical settings.

    Good biosecurity procedures are crucial for healthy animal production. The aim of this study was to quantify the level of biosecurity on conventional broiler farms in Europe, following a standardized procedure, thereby trying to identify factors that are amenable to improvement. The current study used a risk-based weighted scoring system (biocheck.ugent ®) to assess the level of biosecurity on 399 conventional broiler farms in 5 EU member states. The scoring system consisted of 2 main categories, namely external and internal biosecurity, which had 8 and 3 subcategories, respectively. Biosecurity was quantified by converting the answers to 97 questions into a score from 0 to 100. The minimum score, "0," represents total absence of any biosecurity measure on the broiler farm, whereas the maximum score, "100," means full application of all investigated biosecurity measures. A possible correlation between biosecurity and farm characteristics was investigated by multivariate linear regression analysis. The participating broiler farms scored better for internal biosecurity (mean score of 76.6) than for external biosecurity (mean 68.4). There was variation between the mean biosecurity scores for the different member states, ranging from 59.8 to 78.0 for external biosecurity and from 63.0 to 85.6 for internal biosecurity. Within the category of external biosecurity, the subcategory related to "infrastructure and vectors" had the highest mean score (82.4), while the subcategory with the lowest score related to biosecurity procedures for "visitors and staff" (mean 51.5). Within the category of internal biosecurity, the subcategory "disease management" had the highest mean score (65.8). In the multivariate regression model a significant negative correlation was found between internal biosecurity and the number of employees and farm size. These findings indicate that there is a lot of variation for external and internal biosecurity on the participating broiler farms

    Andres Ricardo P. Riera


    Full Text Available Scores aimed at contributing to the optimization of exercise testing (ET have been developed and the experience with their application in coronary artery disease (CAD has proven to be favorable1. Although there is debate on the use of scores in clinical practice, those that stand for it argue that they may decrease the rate of undiagnosed CAD, besides reducing the number of patients without disease that undergo highly expensive tests2. Additionally, scores may be helpful, in a more consistent and organized fashion, in prognosis evaluation and in the adoption of an appropriate plan of action for the triage of this disease in the general population.

    Malhotra, Atul; Younes, Magdy; Kuna, Samuel T.; Benca, Ruth; Kushida, Clete A.; Walsh, James; Hanlon, Alexandra; Staley, Bethany; Pack, Allan I.; Pien, Grace W.


    Study Objectives: Manual scoring of polysomnograms (PSG) is labor intensive and has considerable variance between scorers. Automation of scoring could reduce cost and improve reproducibility. The purpose of this study was to compare a new automated scoring system (YST-Limited, Winnipeg, Canada) with computer-assisted manual scoring. Design: Technical assessment. Setting: Five academic medical centers. Participants: N/A. Interventions: N/A. Measurements and Results: Seventy PSG files were selected at University of Pennsylvania (Penn) and distributed to five US academic sleep centers. Two blinded technologists from each center scored each file. Automatic scoring was performed at Penn by a YST Limited technician using a laptop containing the software. Variables examined were sleep stages, arousals, and apnea-hypopnea index (AHI) using three methods of identifying hypopneas. Automatic scores were not edited and were compared to the average scores of the 10 technologists. Intraclass correlation coefficient (ICC) was obtained for the 70 pairs and compared to across-sites ICCs for manually scored results. ICCs for automatic versus manual scoring were > 0.8 for total sleep time, stage N2, and nonrapid eye movement arousals and > 0.9 for AHI scored by primary and secondary American Academy of Sleep Medicine criteria. ICCs for other variables were not as high but were comparable to the across-site ICCs for manually scored results. Conclusion: The automatic system yielded results that were similar to those obtained by experienced technologists. Very good ICCs were obtained for many primary PSG outcome measures. This automated scoring software, particularly if supplemented with manual editing, may increase laboratory efficiency and standardize PSG scoring results within and across sleep centers.

  10. Do MCAT scores predict USMLE scores? An analysis on 5 years of medical student data

    Directory of Open Access Journals (Sweden)

    Jacqueline L. Gauer


    Full Text Available Introduction: The purpose of this study was to determine the associations and predictive values of Medical College Admission Test (MCAT component and composite scores prior to 2015 with U.S. Medical Licensure Exam (USMLE Step 1 and Step 2 Clinical Knowledge (CK scores, with a focus on whether students scoring low on the MCAT were particularly likely to continue to score low on the USMLE exams. Method: Multiple linear regression, correlation, and chi-square analyses were performed to determine the relationship between MCAT component and composite scores and USMLE Step 1 and Step 2 CK scores from five graduating classes (2011–2015 at the University of Minnesota Medical School (N=1,065. Results: The multiple linear regression analyses were both significant (p<0.001. The three MCAT component scores together explained 17.7% of the variance in Step 1 scores (p<0.001 and 12.0% of the variance in Step 2 CK scores (p<0.001. In the chi-square analyses, significant, albeit weak associations were observed between almost all MCAT component scores and USMLE scores (Cramer's V ranged from 0.05 to 0.24. Discussion: Each of the MCAT component scores was significantly associated with USMLE Step 1 and Step 2 CK scores, although the effect size was small. Being in the top or bottom scoring range of the MCAT exam was predictive of being in the top or bottom scoring range of the USMLE exams, although the strengths of the associations were weak to moderate. These results indicate that MCAT scores are predictive of student performance on the USMLE exams, but, given the small effect sizes, should be considered as part of the holistic view of the student.

    Hwang, Bo Kyung; Yoon, Yeo-Jin; Han, Sang Yun; Lee, Soo Jin; Chae, Han


    The Yin-Yang is a pivotal concept of traditional East-Asian medicine, however the stability of Yin-Yang temperament in Sasang Personality Questionnaire (SPQ) over time has not been extensively studied. The purpose of this study was to examine the test-retest validity of SPQ with a large number of participants. SPQ test was conducted two times with three months interval in 247 Korean university students. The structural validity of first SPQ data was examined with Factor analysis and Cronbach's alpha, and the correlation between first and second measure of SPQ was attested with Pearson's correlation. Yang, Uncertain and Yin temperament groups were determined with SPQ total scores, and agreement of temperament group clustering between first and second measures were analyzed with Cohen's Kappa. Three subscales of SPQ explained 55.25% of total variances, and internal consistency of SPQ total score was 0.772. The correlation coefficient between first and second measures of SPQ were 0.851 and 0.888 in male and female, respectively, and the agreement of first and second Yin-Yang temperament group clustering as Cohen's Kappa was 0.536 for male and 0.637 for female. The repeatability of SPQ measuring Yin-Yang temperament at three months of interval was found to be satisfactory. The SPQ would be a reliable clinical measure for the biopsychological studies of traditional East-Asian medicine.

    Three different ways of combining scores are used in the revised formulation. These are arithmetic mean, geometric mean and multiplication with normalisation. Arithmetic mean is used when combining scores that measure similar attributes, e.g. used for combining costs. The arithmetic mean has the property that it is similar to a logical OR, e.g. when combining costs it does not matter what the individual costs are only what the combined cost is. Geometric mean and Multiplication are used when combining scores that measure disparate attributes. Multiplication is similar to a logical AND, it is used to combine ‘must haves.’ As a result, this method is more punitive than the geometric mean; to get a good score in the combined result it is necessary to have a good score in ALL of the inputs. e.g. the different types of survivability are ‘must haves.’ On balance, the revised TPL is probably less punitive than the previous spreadsheet, multiplication is used sparingly as a method of combining scores. This is in line with the feedback of the Wave Energy Prize judges.

    To determine the formula that predicts the injury severity score from parameters that are obtained in the emergency department at arrival. We reviewed the medical records of trauma patients who were transferred to the emergency department of Gunma University Hospital between January 2010 and December 2010. The injury severity score, age, mean blood pressure, heart rate, Glasgow coma scale, hemoglobin, hematocrit, red blood cell count, platelet count, fibrinogen, international normalized ratio of prothrombin time, activated partial thromboplastin time, and fibrin degradation products, were examined in those patients on arrival. To determine the formula that predicts the injury severity score, multiple linear regression analysis was carried out. The injury severity score was set as the dependent variable, and the other parameters were set as candidate objective variables. IBM spss Statistics 20 was used for the statistical analysis. Statistical significance was set at P  Watson ratio was 2.200. A formula for predicting the injury severity score in trauma patients was developed with ordinary parameters such as fibrin degradation products and mean blood pressure. This formula is useful because we can predict the injury severity score easily in the emergency department.

  2. Pharmacophore-based similarity scoring for DOCK. (United States)

    Jiang, Lingling; Rizzo, Robert C


    Pharmacophore modeling incorporates geometric and chemical features of known inhibitors and/or targeted binding sites to rationally identify and design new drug leads. In this study, we have encoded a three-dimensional pharmacophore matching similarity (FMS) scoring function into the structure-based design program DOCK. Validation and characterization of the method are presented through pose reproduction, crossdocking, and enrichment studies. When used alone, FMS scoring dramatically improves pose reproduction success to 93.5% (∼20% increase) and reduces sampling failures to 3.7% (∼6% drop) compared to the standard energy score (SGE) across 1043 protein-ligand complexes. The combined FMS+SGE function further improves success to 98.3%. Crossdocking experiments using FMS and FMS+SGE scoring, for six diverse protein families, similarly showed improvements in success, provided proper pharmacophore references are employed. For enrichment, incorporating pharmacophores during sampling and scoring, in most cases, also yield improved outcomes when docking and rank-ordering libraries of known actives and decoys to 15 systems. Retrospective analyses of virtual screenings to three clinical drug targets (EGFR, IGF-1R, and HIVgp41) using X-ray structures of known inhibitors as pharmacophore references are also reported, including a customized FMS scoring protocol to bias on selected regions in the reference. Overall, the results and fundamental insights gained from this study should benefit the docking community in general, particularly researchers using the new FMS method to guide computational drug discovery with DOCK.

  3. GalaxyDock BP2 score: a hybrid scoring function for accurate protein-ligand docking (United States)

    Baek, Minkyung; Shin, Woong-Hee; Chung, Hwan Won; Seok, Chaok


    Protein-ligand docking is a useful tool for providing atomic-level understanding of protein functions in nature and design principles for artificial ligands or proteins with desired properties. The ability to identify the true binding pose of a ligand to a target protein among numerous possible candidate poses is an essential requirement for successful protein-ligand docking. Many previously developed docking scoring functions were trained to reproduce experimental binding affinities and were also used for scoring binding poses. However, in this study, we developed a new docking scoring function, called GalaxyDock BP2 Score, by directly training the scoring power of binding poses. This function is a hybrid of physics-based, empirical, and knowledge-based score terms that are balanced to strengthen the advantages of each component. The performance of the new scoring function exhibits significant improvement over existing scoring functions in decoy pose discrimination tests. In addition, when the score is used with the GalaxyDock2 protein-ligand docking program, it outperformed other state-of-the-art docking programs in docking tests on the Astex diverse set, the Cross2009 benchmark set, and the Astex non-native set. GalaxyDock BP2 Score and GalaxyDock2 with this score are freely available at

    Full Text Available Background This is a validation study comparing the European System for Cardiac Operative Risk Evaluation (EuroSCORE II with the previous additive (AES and logistic EuroSCORE (LES and the Society of Thoracic Surgeons’ (STS risk prediction algorithm, for patients undergoing valve replacement with or without bypass in Pakistan. Patients and Methods Clinical data of 576 patients undergoing valve replacement surgery between 2006 and 2013 were retrospectively collected and individual expected risks of death were calculated by all four risk prediction algorithms. Performance of these risk algorithms was evaluated in terms of discrimination and calibration. Results There were 28 deaths (4.8% among 576 patients, which was lower than the predicted mortality of 5.16%, 6.96% and 4.94% by AES, LES and EuroSCORE II but was higher than 2.13% predicted by STS scoring system. For single and double valve replacement procedures, EuroSCORE II was the best predictor of mortality with highest Hosmer and Lemmeshow test (H-L p value (0.346 to 0.689 and area under the receiver operating characteristic (ROC curve (0.637 to 0.898. For valve plus concomitant coronary artery bypass grafting (CABG patients actual mortality was 1.88%. STS calculator came out to be the best predictor of mortality for this subgroup with H-L p value (0.480 to 0.884 and ROC (0.657 to 0.775. Conclusions For Pakistani population EuroSCORE II is an accurate predictor for individual operative risk in patients undergoing isolated valve surgery, whereas STS performs better in the valve plus CABG group.

    Full Text Available INTRODUCTION Diabetic foot ulcers vary in their clinical presentation and nature of severity and therefore create a challenging problem to the treating surgeon regarding the prediction of the clinical course and the end result of the treatment. Clinical studies have shown that there are certain risk factors for the progression of foot ulcers in diabetics and it may therefore be possible to predict the course of an ulcer foot at presentation itself, thus instituting proper therapy without delay. Spoken otherwise clinical scoring may tell that this particular ulcer is having highest chance of amputation, then one may be able to take an early decision for the same and avoid the septic complications, inconvenience to the patient, long hospital stay and cost of treatments. AIM OF THE STUDY Aim of the study is to evaluate the above-mentioned scoring system in predicting the course the diabetic foot ulcers. MATERIALS AND METHODS 50 patients with Diabetic Foot attending the OPD of Department of Surgery of Government Hospital attached to Calicut Medical College are included in the present study. After thorough history taking and clinical examination, six risk factors like Age, pedal vessels, renal function, neuropathy, radiological findings and ulcers were observed in the patients by giving certain scoring points to each of them. The total number of points scored by the patients at the time of admission or OPD treatment was correlated with the final outcome in these patients, whether leading to amputation or conservative management. All the data was analysed using standard statistical methods. OBSERVATIONS AND RESULTS There were 12 females and 38 males with a female to male ratio 1:3.1. All were aged above 30 years. Twenty-four (48% of them were between 30-60 years and twenty six (52% were above 60 years. 10 patients were treated conservatively with risk score range: 10 to 35. Six had single toe loss with risk score: 25 to 35. Six had multiple toe loss

  7. WebScore: An Effective Page Scoring Approach for Uncertain Web Social Networks

    Directory of Open Access Journals (Sweden)

    Shaojie Qiao


    Full Text Available To effectively score pages with uncertainty in web social networks, we first proposed a new concept called transition probability matrix and formally defined the uncertainty in web social networks. Second, we proposed a hybrid page scoring algorithm, called WebScore, based on the PageRank algorithm and three centrality measures including degree, betweenness, and closeness. Particularly,WebScore takes into a full consideration of the uncertainty of web social networks by computing the transition probability from one page to another. The basic idea ofWebScore is to: (1 integrate uncertainty into PageRank in order to accurately rank pages, and (2 apply the centrality measures to calculate the importance of pages in web social networks. In order to verify the performance of WebScore, we developed a web social network analysis system which can partition web pages into distinct groups and score them in an effective fashion. Finally, we conducted extensive experiments on real data and the results show that WebScore is effective at scoring uncertain pages with less time deficiency than PageRank and centrality measures based page scoring algorithms.

  8. Disease severity scoring systems in dermatology

    Cemal Bilaç


    Full Text Available Scoring systems have been developed to interpret the disease severity objectively by evaluating the parameters of the disease. Body surface area, visual analogue scale, and physician global assessment are the most frequently used scoring systems for evaluating the clinical severity of the dermatological diseases. Apart from these scoring systems, many specific scoring systems for many dermatological diseases, including acne (acne vulgaris, acne scars, alopecia (androgenetic alopecia, tractional alopecia, bullous diseases (autoimmune bullous diseases, toxic epidermal necrolysis, dermatitis (atopic dermatitis, contact dermatitis, dyshidrotic eczema, hidradenitis suppurativa, hirsutismus, connective tissue diseases (dermatomyositis, skin involvement of systemic lupus erythematosus (LE, discoid LE, scleroderma, lichen planoplaris, mastocytosis, melanocytic lesions, melasma, onychomycosis, oral lichen planus, pityriasis rosea, psoriasis (psoriasis vulgaris, psoriatic arthritis, nail psoriasis, sarcoidosis, urticaria, and vitiligo, have also been developed. Disease severity scoring methods are ever more extensively used in the field of dermatology for clinical practice to form an opinion about the prognosis by determining the disease severity; to decide on the most suitable treatment modality for the patient; to evaluate the efficacy of the applied medication; and to compare the efficiency of different treatment methods in clinical studies.

    Full Text Available Objective: Myelodysplastic syndrome (MDS is a clonal hematopoietic stem cell disease. Patients are at risk of developing cytopenias or progression to acute myeloid leukemia. Different classifications and prognostic scoring systems have been developed. The aim of this study was to compare the different prognostic scoring systems. Materials and Methods: One hundred and one patients who were diagnosed with primary MDS in 2003-2011 in a tertiary care university hospital’s hematology department were included in the study. Results: As the International Prognostic Scoring System (IPSS, World Health Organization Classification-Based Prognostic Scoring System (WPSS, MD Anderson Prognostic Scoring System (MPSS, and revised IPSS (IPSS-R risk categories increased, leukemia-free survival and overall survival decreased (p<0.001. When the IPSS, WPSS, MPSS, and IPSS-R prognostic systems were compared by Cox regression analysis, the WPSS was the best in predicting leukemia-free survival (p<0.001, and the WPSS (p<0.001 and IPSS-R (p=0.037 were better in predicting overall survival. Conclusion: All 4 prognostic systems were successful in predicting overall survival and leukemia-free survival (p<0.001. The WPSS was found to be the best predictor for leukemia-free survival, while the WPSS and IPSS-R were found to be the best predictors for overall survival.

  10. Gambling scores for earthquake predictions and forecasts (United States)

    Zhuang, Jiancang


    This paper presents a new method, namely the gambling score, for scoring the performance earthquake forecasts or predictions. Unlike most other scoring procedures that require a regular scheme of forecast and treat each earthquake equally, regardless their magnitude, this new scoring method compensates the risk that the forecaster has taken. Starting with a certain number of reputation points, once a forecaster makes a prediction or forecast, he is assumed to have betted some points of his reputation. The reference model, which plays the role of the house, determines how many reputation points the forecaster can gain if he succeeds, according to a fair rule, and also takes away the reputation points betted by the forecaster if he loses. This method is also extended to the continuous case of point process models, where the reputation points betted by the forecaster become a continuous mass on the space-time-magnitude range of interest. We also calculate the upper bound of the gambling score when the true model is a renewal process, the stress release model or the ETAS model and when the reference model is the Poisson model.

    Numerous studies have demonstrated a relationship between adherence to Mediterranean diet and prevention of chronic degenerative diseases. The aim of this study was to validate a novel instrument to measure adherence to Mediterranean diet based on the literature (the MEDI-LITE score). Two-hundred-and-four clinically healthy subjects completed both the MEDI-LITE score and the validated MedDietScore (MDS). Significant positive correlation between the MEDI-LITE and the MDS scores was found in the study population (R = .70; p MEDI-LITE evidenced a significant discriminative capacity between adherents and non-adherents to the Mediterranean diet pattern (optimal cut-off point = 8.50; sensitivity = 96%; specificity = 38%). In conclusion, our findings show that the MEDI-LITE score well correlate with MDS in both global score and in most of the items related to the specific food categories.

    Directory of Open Access Journals (Sweden)

    María Jesús Campión


    Full Text Available In this paper, we study different methods of scoring linguistic expressions defined on a finite set, in the search for a linear order that ranks all those possible expressions. Among them, particular attention is paid to the canonical extension, and its representability through distances in a graph plus some suitable penalization of imprecision. The relationship between this setting and the classical problems of numerical representability of orderings, as well as extension of orderings from a set to a superset is also explored. Finally, aggregation procedures of qualitative rankings and scorings are also analyzed.

    Directory of Open Access Journals (Sweden)

    Dong Xiaoxi


    Full Text Available Abstract Background Development of effective scoring functions is a critical component to the success of protein structure modeling. Previously, many efforts have been dedicated to the development of scoring functions. Despite these efforts, development of an effective scoring function that can achieve both good accuracy and fast speed still presents a grand challenge. Results Based on a coarse-grained representation of a protein structure by using only four main-chain atoms: N, Cα, C and O, we develop a knowledge-based scoring function, called NCACO-score, that integrates different structural information to rapidly model protein structure from sequence. In testing on the Decoys'R'Us sets, we found that NCACO-score can effectively recognize native conformers from their decoys. Furthermore, we demonstrate that NCACO-score can effectively guide fragment assembly for protein structure prediction, which has achieved a good performance in building the structure models for hard targets from CASP8 in terms of both accuracy and speed. Conclusions Although NCACO-score is developed based on a coarse-grained model, it is able to discriminate native conformers from decoy conformers with high accuracy. NCACO is a very effective scoring function for structure modeling.

  6. The scoring of movements in sleep. (United States)

    Walters, Arthur S; Lavigne, Gilles; Hening, Wayne; Picchietti, Daniel L; Allen, Richard P; Chokroverty, Sudhansu; Kushida, Clete A; Bliwise, Donald L; Mahowald, Mark W; Schenck, Carlos H; Ancoli-Israel, Sonia


    The International Classification of Sleep Disorders (ICSD-2) has separated sleep-related movement disorders into simple, repetitive movement disorders (such as periodic limb movements in sleep [PLMS], sleep bruxism, and rhythmic movement disorder) and parasomnias (such as REM sleep behavior disorder and disorders of partial arousal, e.g., sleep walking, confusional arousals, night terrors). Many of the parasomnias are characterized by complex behaviors in sleep that appear purposeful, goal directed and voluntary but are outside the conscious awareness of the individual and therefore inappropriate. All of the sleep-related movement disorders described here have specific polysomnographic findings. For the purposes of developing and/or revising specifications and polysomnographic scoring rules, the AASM Scoring Manual Task Force on Movements in Sleep reviewed background literature and executed evidence grading of 81 relevant articles obtained by a literature search of published articles between 1966 and 2004. Subsequent evidence grading identified limited evidence for reliability and/or validity for polysomnographic scoring criteria for periodic limb movements in sleep, REM sleep behavior disorder, and sleep bruxism. Published scoring criteria for rhythmic movement disorder, excessive fragmentary myoclonus, and hypnagogic foot tremor/alternating leg muscle activation were empirical and based on descriptive studies. The literature review disclosed no published evidence defining clinical consequences of excessive fragmentary myoclonus or hypnagogic foot tremor/alternating leg muscle activation. Because of limited or absent evidence for reliability and/or validity, a standardized RAND/UCLA consensus process was employed for recommendation of specific rules for the scoring of sleep-associated movements.

  10. Comparing Computer-Derived and Human-Observed Scores for the Balance Error Scoring System. (United States)

    Caccese, Jaclyn B; Kaminski, Thomas W


    The Balance Error Scoring System (BESS) is the current standard for assessing postural stability in concussed athletes on the sideline. However, research has questioned the objectivity and validity of the BESS, suggesting that while certain subcategories of the BESS have sufficient reliability to be used in evaluation of postural stability, the total score is not reliable, demonstrating limited interrater and intrarater reliability. Recently, a computerized BESS test was developed to automate scoring. To compare computer-derived BESS scores with those taken from 3 trained human scorers. Interrater reliability study. Athletic training room. NCAA Division I student athletes (53 male, 58 female; 19 ± 2 y, 168 ± 41 cm, 69 ± 4 kg). Subjects were asked to perform the BESS while standing on the Tekscan (Boston, MA) MobileMat® BESS. The MobileMat BESS software displayed an error score at the end of each trial. Simultaneously, errors were recorded by 3 separate examiners. Errors were counted using the standard BESS scoring criteria. The number of BESS errors was computed for the 6 stances from the software and each of the 3 human scorers. Interclass correlation coefficients (ICCs) were used to compare errors for each stance scored by the MobileMat BESS software with each of 3 raters individually. The ICC values were converted to Fisher Z scores, averaged, and converted back into ICC values. The double-leg, single-leg, and tandem-firm stances resulted in good agreement with human scorers (ICC = .999, .731, and .648). All foam stances resulted in fair agreement. Our results suggest that the MobileMat BESS is suitable for identifying BESS errors involving each of the 6 stances of the BESS protocol. Because the MobileMat BESS scores consistently and reliably, this system can be used with confidence by clinicians as an effective alternative to scoring the BESS.

  11. The RIPASA score for the diagnosis of acute appendicitis: A comparison with the modified Alvarado score. (United States)

    Díaz-Barrientos, C Z; Aquino-González, A; Heredia-Montaño, M; Navarro-Tovar, F; Pineda-Espinosa, M A; Espinosa de Santillana, I A


    Acute appendicitis is the first cause of surgical emergencies. It is still a difficult diagnosis to make, especially in young persons, the elderly, and in reproductive-age women, in whom a series of inflammatory conditions can have signs and symptoms similar to those of acute appendicitis. Different scoring systems have been created to increase diagnostic accuracy, and they are inexpensive, noninvasive, and easy to use and reproduce. The modified Alvarado score is probably the most widely used and accepted in emergency services worldwide. On the other hand, the RIPASA score was formulated in 2010 and has greater sensitivity and specificity. There are very few studies conducted in Mexico that compare the different scoring systems for appendicitis. The aim of our article was to compare the modified Alvarado score and the RIPASA score in the diagnosis of patients with abdominal pain and suspected acute appendicitis. An observational, analytic, and prolective study was conducted within the time frame of July 2002 and February 2014 at the Hospital Universitario de Puebla. The questionnaires used for the evaluation process were applied to the patients suspected of having appendicitis. The RIPASA score with 8.5 as the optimal cutoff value: ROC curve (area .595), sensitivity (93.3%), specificity (8.3%), PPV (91.8%), NPV (10.1%). Modified Alvarado score with 6 as the optimal cutoff value: ROC curve (area .719), sensitivity (75%), specificity (41.6%), PPV (93.7%), NPV (12.5%). The RIPASA score showed no advantages over the modified Alvarado score when applied to patients presenting with suspected acute appendicitis.

    Sung Uk Chae


    Full Text Available Purpose Although there have been studies emphasizing the re-education of North Korean (NK doctors for post-unification of the Korean Peninsula, study on the content and scope of such re-education has yet to be conducted. Researchers intended to set the content and scope of re-education by a comparative analysis for the scores of the preliminary examination, which is comparable to the Korean Medical Licensing Examination (KMLE. Methods The scores of the first and second preliminary exams were analyzed by subject using the Wilcoxon signed rank test. The passing status of the group of NK doctors for KMLE in recent 3 years were investigated. The multiple-choice-question (MCQ items of which difficulty indexes of NK doctors were lower than those of South Korean (SK medical students by two times of the standard deviation of the scores of SK medical students were selected to investigate the relevant reasons. Results The average scores of nearly all subjects were improved in the second exam compared with the first exam. The passing rate of the group of NK doctors was 75%. The number of MCQ items of which difficulty indexes of NK doctors were lower than those of SK medical students was 51 (6.38%. NK doctors’ lack of understandings for Diagnostic Techniques and Procedures, Therapeutics, Prenatal Care, and Managed Care Programs was suggested as the possible reason. Conclusion The education of integrated courses focusing on Diagnostic Techniques and Procedures and Therapeutics, and apprenticeship-style training for clinical practice of core subjects are needed. Special lectures on the Preventive Medicine are likely to be required also.

    Srinivasan, R.; Kinser, J.; Schamschula, M.; Shamir, J.; Caulfield, H.J. [Center for Applied Optical Sciences, Department of Physics, Alabama A& M University, Normal, Alabama 35762 (United States)


    A novel syntactic approach is introduced to treat particular problems in pattern recognition. The procedure is implemented by the use of optical correlation methods for identifying the various primitives that appear in the input pattern, and their importance is determined by fuzzy relational scoring. Robust pattern recognition with tolerance to normal variations is demonstrated, indicating an efficient new approach for optical pattern recognition. {copyright} {ital 1996 Optical Society of America.}

  19. Resiliency scoring for business continuity plans. (United States)

    Olson, Anna; Anderson, Jamie

    Through this paper readers will learn of a scoring methodology, referred to as resiliency scoring, which enables the evaluation of business continuity plans based upon analysis of their alignment with a predefined set of criteria that can be customised and are adaptable to the needs of any organisation. This patent pending tool has been successful in driving engagement and is a powerful resource to improve reporting capabilities, identify risks and gauge organisational resilience. The role of business continuity professionals is to aid their organisations in planning and preparedness activities aimed at mitigating the impacts of potential disruptions and ensuring critical business functions can continue in the event of unforeseen circumstances. This may seem like a daunting task for what can typically be a small team of individuals. For this reason, it is important to be able to leverage industry standards, documented best practices and effective tools to streamline and support your continuity programme. The resiliency scoring methodology developed and implemented at Target has proven to be a valuable tool in taking the organisation's continuity programme to the next level. This paper will detail how the tool was developed and provide guidance on how it can be customised to fit your organisation's unique needs.

  20. High throughput sample processing and automated scoring

    Directory of Open Access Journals (Sweden)

    Gunnar eBrunborg


    Full Text Available The comet assay is a sensitive and versatile method for assessing DNA damage in cells. In the traditional version of the assay, there are many manual steps involved and few samples can be treated in one experiment. High throughput modifications have been developed during recent years, and they are reviewed and discussed. These modifications include accelerated scoring of comets; other important elements that have been studied and adapted to high throughput are cultivation and manipulation of cells or tissues before and after exposure, and freezing of treated samples until comet analysis and scoring. High throughput methods save time and money but they are useful also for other reasons: large-scale experiments may be performed which are otherwise not practicable (e.g., analysis of many organs from exposed animals, and human biomonitoring studies, and automation gives more uniform sample treatment and less dependence on operator performance. The high throughput modifications now available vary largely in their versatility, capacity, complexity and costs. The bottleneck for further increase of throughput appears to be the scoring.

  1. Scoring ordinal variables for constructing composite indicators

    Directory of Open Access Journals (Sweden)

    Marica Manisera


    Full Text Available In order to provide composite indicators of latent variables, for example of customer satisfaction, it is opportune to identify the structure of the latent variable, in terms of the assignment of items to the subscales defining the latent variable. Adopting the reflective model, the impact of four different methods of scoring ordinal variables on the identification of the true structure of latent variables is investigated. A simulation study composed of 5 steps is conducted: (1 simulation of population data with continuous variables measuring a two-dimensional latent variable with known structure; (2 draw of a number of random samples; (3 discretization of the continuous variables according to different distributional forms; (4 quantification of the ordinal variables obtained in step (3 according to different methods; (5 construction of composite indicators and verification of the correct assignment of variables to subscales by the multiple group method and the factor analysis. Results show that the considered scoring methods have similar performances in assigning items to subscales, and that, when the latent variable is multinormal, the distributional form of the observed ordinal variables is not determinant in suggesting the best scoring method to use.

  2. Modelling the predictive performance of credit scoring

    Directory of Open Access Journals (Sweden)

    Shi-Wei Shen


    Research purpose: The purpose of this empirical paper was to examine the predictive performance of credit scoring systems in Taiwan. Motivation for the study: Corporate lending remains a major business line for financial institutions. However, in light of the recent global financial crises, it has become extremely important for financial institutions to implement rigorous means of assessing clients seeking access to credit facilities. Research design, approach and method: Using a data sample of 10 349 observations drawn between 1992 and 2010, logistic regression models were utilised to examine the predictive performance of credit scoring systems. Main findings: A test of Goodness of fit demonstrated that credit scoring models that incorporated the Taiwan Corporate Credit Risk Index (TCRI, micro- and also macroeconomic variables possessed greater predictive power. This suggests that macroeconomic variables do have explanatory power for default credit risk. Practical/managerial implications: The originality in the study was that three models were developed to predict corporate firms’ defaults based on different microeconomic and macroeconomic factors such as the TCRI, asset growth rates, stock index and gross domestic product. Contribution/value-add: The study utilises different goodness of fits and receiver operator characteristics during the examination of the robustness of the predictive power of these factors.

    de la Portilla, Fernando; Calero-Lillo, Arantxa; Jiménez-Rodríguez, Rosa M; Reyes, Maria L; Segovia-González, Manuela; Maestre, María Victoria; García-Cabrera, Ana M


    To implement a quick and simple test - rapid assessment faecal incontinence score (RAFIS) and show its reliability and validity. From March 2008 through March 2010, we evaluated a total of 261 consecutive patients, including 53 patients with faecal incontinence. Demographic and comorbidity information was collected. In a single visit, patients were administered the RAFIS. The results obtained with the new score were compared with those of both Wexner score and faecal incontinence quality of life scale (FIQL) questionnaire. The patient without influence of the surgeon completed the test. The role of surgeon was explaining the meaning of each section and how he had to fill. Reliability of the RAFIS score was measured using intra-observer agreement and Cronbach's alpha (internal consistency) coefficient. Multivariate analysis of the main components within the different scores was performed in order to determine whether all the scores measured the same factor and to conclude whether the information could be encompassed in a single factor. A sample size of 50 patients with faecal incontinence was estimated to be enough to detect a correlation of 0.55 or better at 5% level of significance with 80% power. We analysed the results obtained by 53 consecutive patients with faecal incontinence (median age 61.55 ± 12.49 years) in the three scoring systems. A total of 208 healthy volunteers (median age 58.41 ± 18.41 years) without faecal incontinence were included in the study as negative controls. Pearson's correlation coefficient between "state" and "leaks" was excellent (r = 0.92, P < 0.005). Internal consistency in the comparison of "state" and "leaks" yielded also excellent correlation (Cronbach's α = 0.93). Results in each score were compared using regression analysis and a correlation value of r = 0.98 was obtained with Wexner score. As regards FIQL questionnaire, the values of "r" for the different subscales of the questionnaire were: "lifestyle" r = -0.87, "coping

    A consecutive series of 103 patients, 58% male with mean age of 62 year (range 40-75 years), admitted with supratentorial stroke in our teaching hospital were studied. All patients had Computer Tomography scan brain done after clinical evaluation and application of Allen stroke score. Computer Tomography Scan confirmed thrombotic stroke in 55 (53%) patients and haemorrhagic stroke in 48 (47%) patients. Out of the 55 patients with definitive thrombotic stroke on Computer Tomography Scan, Allen stroke score suggested infarction in 67%, haemorrhage in 6% and remained inconclusive in 27% of cases. In 48 patients with definitive haemorrhagic stroke on Computer Tomography Scan, Allen stroke score suggested haemorrhage in 60%, infarction in 11% and remained inconclusive in 29% of cases. The overall accuracy of Allen stroke score was 66%. (author)

  10. Best waveform score for diagnosing keratoconus

    Directory of Open Access Journals (Sweden)

    Allan Luz


    Full Text Available PURPOSE: To test whether corneal hysteresis (CH and corneal resistance factor (CRF can discriminate between keratoconus and normal eyes and to evaluate whether the averages of two consecutive measurements perform differently from the one with the best waveform score (WS for diagnosing keratoconus. METHODS: ORA measurements for one eye per individual were selected randomly from 53 normal patients and from 27 patients with keratoconus. Two groups were considered the average (CH-Avg, CRF-Avg and best waveform score (CH-WS, CRF-WS groups. The Mann-Whitney U-test was used to evaluate whether the variables had similar distributions in the Normal and Keratoconus groups. Receiver operating characteristics (ROC curves were calculated for each parameter to assess the efficacy for diagnosing keratoconus and the same obtained for each variable were compared pairwise using the Hanley-McNeil test. RESULTS: The CH-Avg, CRF-Avg, CH-WS and CRF-WS differed significantly between the normal and keratoconus groups (p<0.001. The areas under the ROC curve (AUROC for CH-Avg, CRF-Avg, CH-WS, and CRF-WS were 0.824, 0.873, 0.891, and 0.931, respectively. CH-WS and CRF-WS had significantly better AUROCs than CH-Avg and CRF-Avg, respectively (p=0.001 and 0.002. CONCLUSION: The analysis of the biomechanical properties of the cornea through the ORA method has proved to be an important aid in the diagnosis of keratoconus, regardless of the method used. The best waveform score (WS measurements were superior to the average of consecutive ORA measurements for diagnosing keratoconus.

  11. Scoring function to predict solubility mutagenesis

    Directory of Open Access Journals (Sweden)

    Deutsch Christopher


    Full Text Available Abstract Background Mutagenesis is commonly used to engineer proteins with desirable properties not present in the wild type (WT protein, such as increased or decreased stability, reactivity, or solubility. Experimentalists often have to choose a small subset of mutations from a large number of candidates to obtain the desired change, and computational techniques are invaluable to make the choices. While several such methods have been proposed to predict stability and reactivity mutagenesis, solubility has not received much attention. Results We use concepts from computational geometry to define a three body scoring function that predicts the change in protein solubility due to mutations. The scoring function captures both sequence and structure information. By exploring the literature, we have assembled a substantial database of 137 single- and multiple-point solubility mutations. Our database is the largest such collection with structural information known so far. We optimize the scoring function using linear programming (LP methods to derive its weights based on training. Starting with default values of 1, we find weights in the range [0,2] so that predictions of increase or decrease in solubility are optimized. We compare the LP method to the standard machine learning techniques of support vector machines (SVM and the Lasso. Using statistics for leave-one-out (LOO, 10-fold, and 3-fold cross validations (CV for training and prediction, we demonstrate that the LP method performs the best overall. For the LOOCV, the LP method has an overall accuracy of 81%. Availability Executables of programs, tables of weights, and datasets of mutants are available from the following web page:

  12. Importance of Scoring Systems in Prognosticating Meningococcemia

    Directory of Open Access Journals (Sweden)

    AR Emami Naeini


    Full Text Available Background: Meningococcal diseases occur with a worldwide distribution as endemic or in epidemics with an overall mortality rate of 8% to 10%, mainly in patients with signs and symptoms of meningococcemia. Several investigators have devised scoring systems using clinical and laboratory parameters available at the time of presentation to prognosticate the outcome of the infection. This study was designed to determine the distribution of demographic, clinical and laboratory parameters among our patients and the relative frequency of individual Stiehm and Damrosch components. Methods: This was a prospective descriptive study, performed on patients with definite diagnosis of meningococcal infection admitted to Al-Zahra University hospital (adult and pediatric wards, Isfahan, Iran, between 1997 and 2002. The cases were 140 patients [99(70.7% males and 41(29.3%females] from 1 to 50 years old (25.5±1.32. Data were collected by filling checklists. SSPS software was applied to analyze the data using chi-square test. Results: In this study, the relative frequency of individual Stiehm and Damrosch components were as follows: hypotension (10.7%, peripheral white blood cell count <10,000/mm3 (39.3%, leukopenia (11.5%, ESR<10 mm/hr (19.3%, coma (6.4%, early widespread petechiae (18%, absence of meningitis (13.6%. Overall mortality rate was (10.7%. Conclusion: Meningococci are still killers, they affect men more than women. Teenagers are at more risk than other age groups. Mortality in our study was a little higher than what is suggested (10.7%. we recommend using scoring systems for early separation of poor prognostic patients to provide them with more special care.

  13. Pediatric siMS score: A new, simple and accurate continuous metabolic syndrome score for everyday use in pediatrics.

    Directory of Open Access Journals (Sweden)

    Rade Vukovic

    Full Text Available The dichotomous nature of the current definition of metabolic syndrome (MS in youth results in loss of information. On the other hand, the calculation of continuous MS scores using standardized residuals in linear regression (Z scores or factor scores of principal component analysis (PCA is highly impractical for clinical use. Recently, a novel, easily calculated continuous MS score called siMS score was developed based on the IDF MS criteria for the adult population.To develop a Pediatric siMS score (PsiMS, a modified continuous MS score for use in the obese youth, based on the original siMS score, while keeping the score as simple as possible and retaining high correlation with more complex scores.The database consisted of clinical data on 153 obese (BMI ≥95th percentile children and adolescents. Continuous MS scores were calculated using Z scores and PCA, as well as the original siMS score. Four variants of PsiMS score were developed in accordance with IDF criteria for MS in youth and correlation of these scores with PCA and Z score derived MS continuous scores was assessed.PsiMS score calculated using formula: (2xWaist/Height + (Glucose(mmol/l/5.6 + (triglycerides(mmol/l/1.7 + (Systolic BP/130-(HDL(mmol/l/1.02 showed the highest correlation with most of the complex continuous scores (0.792-0.901. The original siMS score also showed high correlation with continuous MS scores.PsiMS score represents a practical and accurate score for the evaluation of MS in the obese youth. The original siMS score should be used when evaluating large cohorts consisting of both adults and children.

  14. Setting pass scores for clinical skills assessment. (United States)

    Liu, Min; Liu, Keh-Min


    In a clinical skills assessment, the decision to pass or fail an examinee should be based on the test content or on the examinees' performance. The process of deciding a pass score is known as setting a standard of the examination. This requires a properly selected panel of expert judges and a suitable standard setting method, which best fits the purpose of the examination. Six standard setting methods that are often used in clinical skills assessment are described to provide an overview of the standard setting process.

    Monte-Carlo Tree Search (MCTS) is a successful algorithm used in many state of the art game engines. We propose to improve a MCTS solver when a game has more than two outcomes. It is for example the case in games that can end in draw positions. In this case it improves significantly a MCTS solver to take into account bounds on the possible scores of a node in order to select the nodes to explore. We apply our algorithm to solving Seki in the game of Go and to Connect Four.

  17. Scoring Rules for Subjective Probability Distributions

    DEFF Research Database (Denmark)

    Harrison, Glenn W.; Martínez-Correa, Jimmy; Swarthout, J. Todd

    The theoretical literature has a rich characterization of scoring rules for eliciting the subjective beliefs that an individual has for continuous events, but under the restrictive assumption of risk neutrality. It is well known that risk aversion can dramatically affect the incentives to correctly...... report the true subjective probability of a binary event, even under Subjective Expected Utility. To address this one can “calibrate” inferences about true subjective probabilities from elicited subjective probabilities over binary events, recognizing the incentives that risk averse agents have...... reliably elicit most important features of the latent subjective belief distribution without undertaking calibration for risk attitudes providing one is willing to assume Subjective Expected Utility....

  1. High-Throughput Scoring of Seed Germination. (United States)

    Ligterink, Wilco; Hilhorst, Henk W M


    High-throughput analysis of seed germination for phenotyping large genetic populations or mutant collections is very labor intensive and would highly benefit from an automated setup. Although very often used, the total germination percentage after a nominated period of time is not very informative as it lacks information about start, rate, and uniformity of germination, which are highly indicative of such traits as dormancy, stress tolerance, and seed longevity. The calculation of cumulative germination curves requires information about germination percentage at various time points. We developed the GERMINATOR package: a simple, highly cost-efficient, and flexible procedure for high-throughput automatic scoring and evaluation of germination that can be implemented without the use of complex robotics. The GERMINATOR package contains three modules: (I) design of experimental setup with various options to replicate and randomize samples; (II) automatic scoring of germination based on the color contrast between the protruding radicle and seed coat on a single image; and (III) curve fitting of cumulative germination data and the extraction, recap, and visualization of the various germination parameters. GERMINATOR is a freely available package that allows the monitoring and analysis of several thousands of germination tests, several times a day by a single person.

  2. Ripasa score: a new diagnostic score for diagnosis of acute appendicitis

    International Nuclear Information System (INIS)

    Butt, M.Q.


    Objective: To determine the usefulness of RIPASA score for the diagnosis of acute appendicitis using histopathology as a gold standard. Study Design: Cross-sectional study. Place and Duration of Study: Department of General Surgery, Combined Military Hospital, Kohat, from September 2011 to March 2012. Methodology: A total of 267 patients were included in this study. RIPASA score was assessed. The diagnosis of appendicitis was made clinically aided by routine sonography of abdomen. After appendicectomies, resected appendices were sent for histopathological examination. The 15 parameters and the scores generated were age (less than 40 years = 1 point; greater than 40 years = 0.5 point), gender (male = 1 point; female = 0.5 point), Right Iliac Fossa (RIF) pain (0.5 point), migration of pain to RIF (0.5 point), nausea and vomiting (1 point), anorexia (1 point), duration of symptoms (less than 48 hours = 1 point; more than 48 hours = 0.5 point), RIF tenderness (1 point), guarding (2 points), rebound tenderness (1 point), Rovsing's sign (2 points), fever (1 point), raised white cell count (1 point), negative urinalysis (1 point) and foreign national registration identity card (1 point). The optimal cut-off threshold score from the ROC was 7.5. Sensitivity analysis was done. Results: Out of 267 patients, 156 (58.4%) were male while remaining 111 patients (41.6%) were female with mean age of 23.5 +- 9.1 years. Sensitivity of RIPASA score was 96.7%, specificity 93.0%, diagnostic accuracy was 95.1%, positive predictive value was 94.8% and negative predictive value was 95.54%. Conclusion: RIPASA score at a cut-off total score of 7.5 was a useful tool to diagnose appendicitis, in equivocal cases of pain. (author)

  8. [Validation of a diagnostic scoring system (Ohmann score) in acute appendicitis]. (United States)

    Zielke, A; Sitter, H; Rampp, T A; Schäfer, E; Hasse, C; Lorenz, W; Rothmund, M


    A diagnostic scoring system, recently published by Ohmann et al. in this journal, was validated by analyzing the clinicopathological data of a consecutive series of 2,359 patients, admitted for suspicion of acute appendicitis. The results of the scoring system were compared to the results of clinical evaluation by junior (provisional) and senior surgeons (final clinical diagnosis). To assess the diagnostic ability of the score, the accuracy and positive predictive value were defined as the major diagnostic performance parameters; the rate of theoretical negative laparotomies and that of diagnostic errors served as the major procedural performance parameters. Of 2,359 patients admitted for suspected acute appendicitis, 662 were proven to have acute appendicitis by histology, for a prevalence of 28%. The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the provisional clinical diagnosis were 0.50, 0.94, 0.77, 0.83, and 0.82; 0.93, for the score 0.63, 0.93, 0.77, 0.86 and 0.84, and for the final clinical diagnosis 0.90, 0.94, 0.85, 0.96, and 0.93, respectively. Of the main diagnostic performance parameter, the accuracy of the score was significantly better than that of provisional clinical diagnosis (P apendicitis, the score demonstrated a superior performance, with only 6 cases missed (0.9%). However, the number of patients with acute appendicitis, including those with perforated disease, who were not identified by the score, was almost four times that of the final clinical diagnosis (245 vs 63). With regard to the main procedural performance parameter, the score resulted in a significantly smaller number of diagnostic errors than the provisional clinical investigator (P < 0.05, chi 2 test). The results of this study indicate that the diagnostic scoring system might be helpful when experienced investigators or additional diagnostic modalities such as ultrasonography are not available. It may therefore be of value

  12. Prognostic Utility of Clinical Epilepsy Severity Score Versus Pretreatment Hypsarrhythmia Scoring in Children With West Syndrome. (United States)

    Sehgal, Rachna; Gulati, Sheffali; Sapra, Savita; Tripathi, Manjari; Pandey, Ravinder Mohan; Kabra, Madhulika


    This cross-sectional study assessed the impact of clinical epilepsy severity and pretreatment hypsarrhythmia severity on epilepsy and cognitive outcomes in treated children with West syndrome. Thirty-three children, aged 1 to 5 years, with infantile spasms were enrolled if pretreatment EEG records were available, after completion of ≥1 year of onset of spasms. Neurodevelopment was assessed by Development Profile 3 and Gross Motor Function Classification System. Epilepsy severity in the past 1 year was determined by the Early Childhood Epilepsy Severity Score (E-Chess). Kramer Global Score of hypsarrhythmia severity was computed. Kramer Global Score (≤8) and E-Chess (≤9) in the past 1 year were associated with favorable epilepsy outcome but not neurodevelopmental or motor outcome.

  13. Do efficiency scores depend on input mix?

    Asmild, Mette; Hougaard, Jens Leth; Kronborg, Dorte


    In this paper we examine the possibility of using the standard Kruskal-Wallis (KW) rank test in order to evaluate whether the distribution of efficiency scores resulting from Data Envelopment Analysis (DEA) is independent of the input (or output) mix of the observations. Since the DEA frontier...... is estimated, many standard assumptions for evaluating the KW test statistic are violated. Therefore, we propose to explore its statistical properties by the use of simulation studies. The simulations are performed conditional on the observed input mixes. The method, unlike existing approaches...... the assumption of mix independence is rejected the implication is that it, for example, is impossible to determine whether machine intensive project are more or less efficient than labor intensive projects....

    Purpose: We evaluated the reproducibility of three visual scoring methods of emphysema and compared these methods with pulmonary function tests (VC, DLCO, FEV1 and FEV%) among farmer's lung patients and farmers. Material and Methods: Three radiologists examined high-resolution CT images of farmer's lung patients and their matched controls (n=70) for chronic interstitial lung diseases. Intraobserver reproducibility and interobserver variability were assessed for three methods: severity, Sanders' (extent) and Sakai. Pulmonary function tests as spirometry and diffusing capacity were measured. Results: Intraobserver -values for all three methods were good (0.51-0.74). Interobserver varied from 0.35 to 0.72. The Sanders' and the severity methods correlated strongly with pulmonary function tests, especially DLCO and FEV1. Conclusion: The Sanders' method proved to be reliable in evaluating emphysema, in terms of good consistency of interpretation and good correlation with pulmonary function tests.

    International Nuclear Information System (INIS)

    Beslic, S.; Dalagija, F.


    Background. The aim of this study was to evaluate coronary artery calcium scoring and the assessment of the risk factors in patients with myocardial infarction (MI). Methods. During the period of three years, 27 patients with MI were analyzed. The average age of patients was 66.1 years (46 to 81). Coronary arteries calcium was evaluated by multi row detector computed tomography (MTDC) S omatom Volume Zoom Siemens , and, retrospectively by ECG gating data acquisition. Semi automated calcium quantification to calculate Agatston calcium score (CS) was performed with 4 x 2.5 mm collimation, using 130 ml of contrast medium, injected with an automatic injector, with the flow rate of 4 ml/sec. The delay time was determined empirically. At the same time several risk factors were evaluated. Results. Out of 27 patients with MI, 3 (11.1%) patients had low CS (10- 100), 5 (18.5%) moderate CS (101- 499), and 19 (70.4%) patients high CS (>500). Of risk factors, smoking was confirmed in 17 (63.0%), high blood pressure (HTA) in 10 (57.0%), diabetes mellitus in 7 (25.9%), positive family history in 5 (18.5%), pathological lipids in 5 (18.5%), alcohol abuse in 4 (1.8%) patients. Six (22.2%) patients had symptoms of angina pectoris. Conclusions. The research showed high correlation of MI and high CS (>500). Smoking, HTA, diabetes mellitus, positive family history and hypercholesterolemia are significant risk factors. Symptoms are relatively poor in large number of patients. (author)

  20. Prediction of true test scores from observed item scores and ancillary data. (United States)

    Haberman, Shelby J; Yao, Lili; Sinharay, Sandip


    In many educational tests which involve constructed responses, a traditional test score is obtained by adding together item scores obtained through holistic scoring by trained human raters. For example, this practice was used until 2008 in the case of GRE(®) General Analytical Writing and until 2009 in the case of TOEFL(®) iBT Writing. With use of natural language processing, it is possible to obtain additional information concerning item responses from computer programs such as e-rater(®). In addition, available information relevant to examinee performance may include scores on related tests. We suggest application of standard results from classical test theory to the available data to obtain best linear predictors of true traditional test scores. In performing such analysis, we require estimation of variances and covariances of measurement errors, a task which can be quite difficult in the case of tests with limited numbers of items and with multiple measurements per item. As a consequence, a new estimation method is suggested based on samples of examinees who have taken an assessment more than once. Such samples are typically not random samples of the general population of examinees, so that we apply statistical adjustment methods to obtain the needed estimated variances and covariances of measurement errors. To examine practical implications of the suggested methods of analysis, applications are made to GRE General Analytical Writing and TOEFL iBT Writing. Results obtained indicate that substantial improvements are possible both in terms of reliability of scoring and in terms of assessment reliability. © 2015 The British Psychological Society.

Plate imaging approaches using both digital camera and office flatbed scanners are included, along with a protocol for the extraction of colony size measurements from the resulting images. A commonly used genetic interaction scoring method, calculation of the S-score, is discussed. These methods require minimal computer skills, but some familiarity with MATLAB and Linux/Unix is a plus. Finally, an outline for using clustering and visualization software for analysis of resulting data sets is provided. © 2018 Cold Spring Harbor Laboratory Press.

  2. Proportional Distribution of Patient Satisfaction Scores by Clinical Service

    Directory of Open Access Journals (Sweden)

    Michael S Leonard MD, MS


    Full Text Available The Proportional Responsibility for Integrated Metrics by Encounter (PRIME model is a novel means of allocating patient experience scores based on the proportion of each physician's involvement in care. Secondary analysis was performed on Hospital Consumer Assessment of Healthcare Providers and Systems surveys from a tertiary care academic institution. The PRIME model was used to calculate specialty-level scores based on encounters during a hospitalization. Standard and PRIME scores for services with the most inpatient encounters were calculated. Hospital medicine had the most discharges and encounters. The standard model generated a score of 74.6, while the PRIME model yielded a score of 74.9. The standard model could not generate a score for anesthesiology due to the lack of returned surveys, but the PRIME model yielded a score of 84.2. The PRIME model provides a more equitable method for distributing satisfaction scores and can generate scores for specialties that the standard model cannot.

  3. Braden Scale cumulative score versus subscale scores: are we missing opportunities for pressure ulcer prevention? (United States)

    Gadd, Molly M


    Hospital-acquired pressure ulcer incidence rates continue to rise in the United States in the acute care setting despite efforts to extinguish them, and pressure ulcers are a nursing-sensitive quality indicator. The Braden Scale for Predicting Pressure Sore Risk instrument has been shown to be a valid and reliable instrument for assessing pressure ulcer risk. This case study represented 1 patient out of a chart audit that reviewed 20 patients with confirmed hospital-acquired pressure ulcers. The goal of the audit was to determine whether these ulcers might be avoided if preventive interventions based on Braden subscale scores versus the cumulative score were implemented. This case study describes a patient who, deemed at low risk for pressure ulcer development based on cumulative Braden Scale, may have benefited from interventions based on the subscale scores of sensory perception, activity, and mobility. Further research is needed to determine whether interventions based on subscales may be effective for preventing pressure ulcers when compared to a protocol based exclusively on the cumulative score.

    Renal dysfunction (RD) is a serious and common complication in a patient with liver cirrhosis. It provides a poor prognosis. The aim of our study was to evaluate the renal function in liver cirrhosis, also to determine the correlation with the graduation of liver disease assessed by Child-Pugh Score (CPS) and MELD score. This was a cross-sectional study included patients with liver cirrhosis admitted to Adam Malik Hospital Medan in June - August 2016. We divided them into two groups as not having renal dysfunction (serum creatinine SPSS 22.0 was used. Statistical methods used: Chi-square, Fisher exact, one way ANOVA, Kruskal Wallis test and Pearson coefficient of correlation. The level of significance was p<0.05. 55 patients with presented with renal dysfunction were 16 (29.1 %). There was statistically significant inverse correlation between GFR and CPS (r = -0.308), GFR and MELD score (r = -0.278). There was a statistically significant correlation between creatinine and MELD score (r = 0.359), creatinine and CPS (r = 0.382). The increase of the degree of liver damage is related to the increase of renal dysfunction.

    A bacterial infection by Borrelia burgdorferi referred to as Lyme disease (LD) or borreliosis is transmitted mostly by a bite of the tick Ixodes scapularis in the USA and Ixodes ricinus in Europe. Various tests are used for the diagnosis of LD, but their results are often unreliable. We compiled a list of clinically visible and patient-reported symptoms that are associated with LD. Based on this list, we developed a novel scoring system. Nutech functional Score (NFS), which is a 43 point positional (every symptom is subgraded and each alternative gets some points according to its position) and directional (moves in direction bad to good) scoring system that assesses the patient's condition. The grades of the scoring system have been converted into numeric values for conducting probability based studies. Each symptom is graded from 1 to 5 that runs in direction BAD → GOOD. NFS is a unique tool that can be used universally to assess the condition of patients with LD.

  12. Surgically treated spinal metastases: Do prognostic scores have a role? (United States)

    Afsar, Afifa; Qadeer, Mohsin; Sharif, Salman


    The outcome for patients with metastatic disease in spine is difficult to predict. Multiple scoring systems were utilized in this study to determine their effectiveness in predicting long-term prognoses. A retrospective analysis of surgically treated patients of spinal metastasis was performed between 2005 and 2016. Data were collected prospectively during which 8 patients were lost to follow-up. Ultimately, data from 63 patients were reviewed. Treatment and prognoses were analyzed utilizing various scoring systems including the SINS, the Tomita, the modified Tokouhashi and Bauer scores. Records of 63 patients, averaging 54 years of age, were analyzed. The Tomita score was applied in 44 patients, a modified Bauer score was studied in 49 patients, while SINS and modified Tokouhashi scores were calculated in all 63 patients. The hazard ratios for the Tomita score were 1, 0.030, 0.622, and 0.272, respectively. The hazard ratios for the modified Bauer scores were 1, 4.663, and 1.622, respectively. The Tokouhashi ratios were 1, 1.656, and 0.501, respectively. Of interest, the Tomita scores provided the highest statistical significance ( P = 0.000) followed by the Bauer ( P = 0.002) and Tokuhashi scores ( P = 0.003). Notably, the SINS score showed no significant correlation in predicting patient survival. For evaluating the metastatic spine disease, this study evaluated the prognostic efficacy of four widely used scores: the Tomita, score, the modified Tokouhashi and Bauer scores, and the SINS scores. The Tomita scores provided the highest statistical significance, followed by the Bauer, and Tokuhashi scores, while the SINS score showed no significant correlation in predicting patient survival.

  13. Rates of computational errors for scoring the SIRS primary scales. (United States)

    Tyner, Elizabeth A; Frederick, Richard I


    We entered item scores for the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1991) into a spreadsheet and compared computed scores with those hand-tallied by examiners. We found that about 35% of the tests had at least 1 scoring error. Of SIRS scale scores tallied by examiners, about 8% were incorrectly summed. When the errors were corrected, only 1 SIRS classification was reclassified in the fourfold scheme used by the SIRS. We note that mistallied scores on psychological tests are common, and we review some strategies for reducing scale score errors on the SIRS. (c) 2013 APA, all rights reserved.

  15. Use of allele scores as instrumental variables for Mendelian randomization. (United States)

    Burgess, Stephen; Thompson, Simon G


    An allele score is a single variable summarizing multiple genetic variants associated with a risk factor. It is calculated as the total number of risk factor-increasing alleles for an individual (unweighted score), or the sum of weights for each allele corresponding to estimated genetic effect sizes (weighted score). An allele score can be used in a Mendelian randomization analysis to estimate the causal effect of the risk factor on an outcome. Data were simulated to investigate the use of allele scores in Mendelian randomization where conventional instrumental variable techniques using multiple genetic variants demonstrate 'weak instrument' bias. The robustness of estimates using the allele score to misspecification (for example non-linearity, effect modification) and to violations of the instrumental variable assumptions was assessed. Causal estimates using a correctly specified allele score were unbiased with appropriate coverage levels. The estimates were generally robust to misspecification of the allele score, but not to instrumental variable violations, even if the majority of variants in the allele score were valid instruments. Using a weighted rather than an unweighted allele score increased power, but the increase was small when genetic variants had similar effect sizes. Naive use of the data under analysis to choose which variants to include in an allele score, or for deriving weights, resulted in substantial biases. Allele scores enable valid causal estimates with large numbers of genetic variants. The stringency of criteria for genetic variants in Mendelian randomization should be maintained for all variants in an allele score.

  16. Bronchiolitis Score of Sant Joan de Déu: BROSJOD Score, validation and usefulness. (United States)

    Balaguer, Mònica; Alejandre, Carme; Vila, David; Esteban, Elisabeth; Carrasco, Josep L; Cambra, Francisco José; Jordan, Iolanda


    To validate the bronchiolitis score of Sant Joan de Déu (BROSJOD) and to examine the previously defined scoring cutoff. Prospective, observational study. BROSJOD scoring was done by two independent physicians (at admission, 24 and 48 hr). Internal consistency of the score was assessed using Cronbach's α. To determine inter-rater reliability, the concordance correlation coefficient estimated as an intraclass correlation coefficient (CCC) and limits of agreement estimated as the 90% total deviation index (TDI) were estimated. An expert opinion was used to classify patients according to clinical severity. A validity analysis was conducted comparing the 3-level classification score to that expert opinion. Volume under the surface (VUS), predictive values, and probability of correct classification (PCC) were measured to assess discriminant validity. About 112 patients were recruited, 62 of them (55.4%) males. Median age: 52.5 days (IQR: 32.75-115.25). The admission Cronbach's α was 0.77 (CI95%: 0.71; 0.82) and at 24 hr it was 0.65 (CI95%: 0.48; 0.7). The inter-rater reliability analysis was: CCC at admission 0.96 (95%CI 0.94-0.97), at 24 h 0.77 (95%CI 0.65-0.86), and at 48 hr 0.94 (95%CI 0.94-0.97); TDI 90%: 1.6, 2.9, and 1.57, respectively. The discriminant validity at admission: VUS of 0.8 (95%CI 0.70-0.90), at 24 h 0.92 (95%CI 0.85-0.99), and at 48 hr 0.93 (95%CI 0.87-0.99). The predictive values and PCC values were within 38-100% depending on the level of clinical severity. There is a high inter-rater reliability, showing the BROSJOD score to be reliable and valid, even when different observers apply it.

  19. Utility of coronary calcium score in women

    Directory of Open Access Journals (Sweden)

    María C. Trejo


    Full Text Available Coronary artery disease is a major cause of death and disability among women, worldwide, particularly during the postmenopausal state, with the caveat that their presenting symptoms are atypical compared to men. Also, there is conflicting data regarding the ideal method to determine their risk, particularly for primary prevention. During this review, we sought to determine the utility of the coronary calcium score for assessing such risk in asymptomatic women, by reviewing the most representative current data and analyzing additional studies to help improve the understanding of mechanisms of coronary artery calcification and determine better strategies of prevention and treatment in women with a positive CCS. Resumen: La enfermedad arterial coronaria es una causa importante de mortalidad y discapacidad en mujeres en el mundo, especialmente durante la postmenopausia, con la salvedad de que presentan síntomas atípicos comparados con los hombres. Además, existen datos contradictorios en cuanto al método para determinar su riesgo, en particular para la prevención primaria. En esta revisión se busca determinar la utilidad del puntaje de calcio coronario para determinar tal riesgo en mujeres asintomáticas, al revisar los datos actuales más representativos y analizar estudios adicionales para ayudar a mejorar la comprensión de los mecanismos de la calcificación de las arterias coronarias, y definir mejores estrategias de prevención y tratamiento en mujeres con un puntaje de calcio coronario positivo.

  20. Scoring system to preoperatively predict choledocholithiasis. (United States)

    Kamath, Sheshang U; Dharap, Satish B; Kumar, Vineet


    The incidence of common bile duct (CBD) calculi has been reported to be 8 % to 20 % among the patients with cholelithiasis. Failure to detect CBD stones on the part of the surgeon not only fails to relieve symptoms but also subjects them to potentially life-threatening complications such as cholangitis, pancreatitis or obstructive jaundice. Modalities for detection of CBD stones have evolved over time from CBD exploration based on clinical and operative findings to intraoperative cholangiography (IOC), to endoscopic retrograde cholangiopancreaticography (ERCP) and, recently, to magnetic resonance cholangiopancreaticography (MRCP) and endoscopic ultrasonography (EUS). We felt a need for a scoring system to predict a patient population having a higher risk of choledocholithiasis so that these modern interventions can be selectively utilized. This study was performed in a tertiary care medical college hospital in a metropolitan city. This is a prospective observational study. All patients with symptomatic cholelithiasis admitted to the hospital were included. Patients were diagnosed as having choledocholithiasis either by ultrasonography (USG), computed tomography scan, MRCP, EUS or ERCP and were followed up for at least 6 weeks. The prevalence of choledocholithiasis among the 275 patients with symptomatic biliary colic in our study was 18.9 % (n = 77). On bivariate analysis, dilated bile duct on USG (>6 mm), raised total bilirubin, raised alkaline phosphatase (ALP), raised amylase, raised SGPT and SGOT were significantly associated with choledocholithiasis (p choledocholithiasis (p 6 mm), total bilirubin >2 mg/dL, ALP >190 IU/L and SGOT >40 IU/L. A positive predictive value of 3 or more factors was over 95 %, necessitating an endoscopic intervention. A negative predictive value of the absence of any factor was 100 %, which ruled out CBD calculi. If only one or two factors are positive, then further evaluation is recommended preferably using non

  1. Gambling score in earthquake prediction analysis (United States)

    Molchan, G.; Romashkova, L.


    The number of successes and the space-time alarm rate are commonly used to characterize the strength of an earthquake prediction method and the significance of prediction results. It has been recently suggested to use a new characteristic to evaluate the forecaster's skill, the gambling score (GS), which incorporates the difficulty of guessing each target event by using different weights for different alarms. We expand parametrization of the GS and use the M8 prediction algorithm to illustrate difficulties of the new approach in the analysis of the prediction significance. We show that the level of significance strongly depends (1) on the choice of alarm weights, (2) on the partitioning of the entire alarm volume into component parts and (3) on the accuracy of the spatial rate measure of target events. These tools are at the disposal of the researcher and can affect the significance estimate. Formally, all reasonable GSs discussed here corroborate that the M8 method is non-trivial in the prediction of 8.0 ≤M < 8.5 events because the point estimates of the significance are in the range 0.5-5 per cent. However, the conservative estimate 3.7 per cent based on the number of successes seems preferable owing to two circumstances: (1) it is based on relative values of the spatial rate and hence is more stable and (2) the statistic of successes enables us to construct analytically an upper estimate of the significance taking into account the uncertainty of the spatial rate measure.

  2. Nutech functional score: A novel scoring system to assess spinal cord injury patients. (United States)

    Shroff, Geeta; Barthakur, Jitendra Kumar


    To develop a new scoring system, nutech functional scores (NFS) for assessing the patients with spinal cord injury (SCI). The conventional scale, American Spinal Injury Association's (ASIA) impairment scale is a measure which precisely describes the severity of the SCI. However, it has various limitations which lead to incomplete assessment of SCI patients. We have developed a 63 point scoring system, i . e ., NFS for patients suffering with SCI. A list of symptoms either common or rare that were found to be associated with SCI was recorded for each patient. On the basis of these lists, we have developed NFS. These lists served as a base to prepare NFS, a 63 point positional (each symptom is sub-graded and get points based on position) and directional (moves in direction BAD → GOOD) scoring system. For non-progressive diseases, 1, 2, 3, 4, 5 denote worst, bad, moderate, good and best (normal), respectively. NFS for SCI has been divided into different groups based on the affected part of the body being assessed, i . e ., motor assessment (shoulders, elbow, wrist, fingers-grasp, fingers-release, hip, knee, ankle and toe), sensory assessment, autonomic assessment, bed sore assessment and general assessment. As probability based studies required a range of (-1, 1) or at least the range of (0, 1) to be useful for real world analysis, the grades were converted to respective numeric values. NFS can be considered as a unique tool to assess the improvement in patients with SCI as it overcomes the limitations of ASIA impairment scale.

  3. Comparing TACOM scores with subjective workload scores measured by NASA-TLX technique

    Energy Technology Data Exchange (ETDEWEB)

    Park, Jin Kyun; Jung, Won Dea [Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)


    It is a well-known fact that a large portion of human performance related problems was attributed to the complexity of tasks. Therefore, managing the complexity of tasks is a prerequisite for safety-critical systems such as nuclear power plants (NPPs), because the consequence of a degraded human performance could be more severe than in other systems. From this concern, it is necessary to quantify the complexity of emergency tasks that are stipulated in procedures, because most tasks of NPPs have been specified in the form of procedures. For this reason, Park et al. developed a task complexity measure called TACOM. In this study, in order to confirm the validity of the TACOM measure, subjective workload scores that were measured by the NASA-TLX technique were compared with the associated TACOM scores. To do this, 23 emergency tasks of the reference NPPs were selected, and then subjective workload scores for these emergency tasks were quantified by 18 operators who had a sufficient knowledge about emergency operations.

    Gardner, Andrew; Forson, Paa Kobina; Oduro, George; Stewart, Barclay; Dike, Nkechi; Glover, Paul; Maio, Ronald F


    The Kampala Trauma Score (KTS) has been proposed as a triage tool for use in low- and middle-income countries (LMICs). This study aimed to examine the diagnostic accuracy of KTS in predicting emergency department outcomes using timely injury estimation with Abbreviated Injury Scale (AIS) score and physician opinion to calculate KTS scores. This was a diagnostic accuracy study of KTS among injured patients presenting to Komfo Anokye Teaching Hospital A&E, Ghana. South African Triage Scale (SATS); KTS component variables, including AIS scores and physician opinion for serious injury quantification; and ED disposition were collected. Agreement between estimated AIS score and physician opinion were analyzed with normal, linear weighted, and maximum kappa. Receiver operating characteristic (ROC) analysis of KTS-AIS and KTS-physician opinion was performed to evaluate each measure's ability to predict A&E mortality and need for hospital admission to the ward or theatre. A total of 1053 patients were sampled. There was moderate agreement between AIS criteria and physician opinion by normal (κ=0.41), weighted (κ lin =0.47), and maximum (κ max =0.53) kappa. A&E mortality ROC area for KTS-AIS was 0.93, KTS-physician opinion 0.89, and SATS 0.88 with overlapping 95% confidence intervals (95%CI). Hospital admission ROC area for KTS-AIS was 0.73, KTS-physician opinion 0.79, and SATS 0.71 with statistical similarity. When evaluating only patients with serious injuries, KTS-AIS (ROC 0.88) and KTS-physician opinion (ROC 0.88) performed similarly to SATS (ROC 0.78) in predicting A&E mortality. The ROC area for KTS-AIS (ROC 0.71; 95%CI 0.66-0.75) and KTS-physician opinion (ROC 0.74; 95%CI 0.69-0.79) was significantly greater than SATS (ROC 0.57; 0.53-0.60) with regard to need for admission. KTS predicted mortality and need for admission from the ED well when early estimation of the number of serious injuries was used, regardless of method (i.e. AIS criteria or physician opinion

    Reliable and easy to perform functional scales are a prerequisite for future therapeutic trials in cerebellar ataxias. In order to assess the specificity of quantitative functional tests of cerebellar dysfunction, we investigated 123 controls, 141 patients with an autosomal dominant cerebellar ataxia (ADCA) and 53 patients with autosomal dominant spastic paraplegia (ADSP). We evaluated four different functional tests (nine-hole pegboard, click, tapping and writing tests), in correlation with the scale for the assessment and rating of cerebellar ataxia (SARA), the scale of functional disability on daily activities (part IV of the Huntington disease rating scale), depression (the Public Health Questionnaire PHQ-9) and the EQ-5D visual analogue scale for self-evaluation of health status. There was a significant correlation between each functional test and a lower limb score. The performance of controls on the functional tests was significantly correlated with age. Subsequent analyses were therefore adjusted for this factor. The performances of ADCA patients on the different tests were significantly worse than that of controls and ADSP patients; there was no difference between ADSP patients and controls. Linear regression analysis showed that only two independent tests, the nine-hole pegboard and the click test on the dominant side (P functional severity (CCFS) score calculated as follows: [Formula: see text]. The CCFS score was significantly higher in ADCA patients compared to controls (1.12 +/- 0.18 versus 0.85 +/- 0.05, P(c) < 0.0001) and ADSP patients (1.12 +/- 0.18 versus 0.90 +/- 0.08, P(c) < 0.0001) and was correlated with disease duration (P < 0.0001) but independent of self-evaluated depressive mood in ADCA. Among genetically homogeneous subgroups of ADCA patients (Spinocerebellar ataxia 1, 2, 3), SCA3 patients had significantly lower (better) CCFS scores than SCA2 (P(c) < 0.04) and the same tendency was observed in SCA1. Their CCFS scores remained

  5. Score based procedures for the calculation of forensic likelihood ratios - Scores should take account of both similarity and typicality. (United States)

    Morrison, Geoffrey Stewart; Enzinger, Ewald


    Score based procedures for the calculation of forensic likelihood ratios are popular across different branches of forensic science. They have two stages, first a function or model which takes measured features from known-source and questioned-source pairs as input and calculates scores as output, then a subsequent model which converts scores to likelihood ratios. We demonstrate that scores which are purely measures of similarity are not appropriate for calculating forensically interpretable likelihood ratios. In addition to taking account of similarity between the questioned-origin specimen and the known-origin sample, scores must also take account of the typicality of the questioned-origin specimen with respect to a sample of the relevant population specified by the defence hypothesis. We use Monte Carlo simulations to compare the output of three score based procedures with reference likelihood ratio values calculated directly from the fully specified Monte Carlo distributions. The three types of scores compared are: 1. non-anchored similarity-only scores; 2. non-anchored similarity and typicality scores; and 3. known-source anchored same-origin scores and questioned-source anchored different-origin scores. We also make a comparison with the performance of a procedure using a dichotomous "match"/"non-match" similarity score, and compare the performance of 1 and 2 on real data.

  6. Dual-energy X-ray absorptiometry diagnostic discordance between Z-scores and T-scores in young adults.

    LENUS (Irish Health Repository)

    Carey, John J


    Diagnostic criteria for postmenopausal osteoporosis using central dual-energy X-ray absorptiometry (DXA) T-scores have been widely accepted. The validity of these criteria for other populations, including premenopausal women and young men, has not been established. The International Society for Clinical Densitometry (ISCD) recommends using DXA Z-scores, not T-scores, for diagnosis in premenopausal women and men aged 20-49 yr, though studies supporting this position have not been published. We examined diagnostic agreement between DXA-generated T-scores and Z-scores in a cohort of men and women aged 20-49 yr, using 1994 World Health Organization and 2005 ISCD DXA criteria. Four thousand two hundred and seventy-five unique subjects were available for analysis. The agreement between DXA T-scores and Z-scores was moderate (Cohen\\'s kappa: 0.53-0.75). The use of Z-scores resulted in significantly fewer (McNemar\\'s p<0.001) subjects diagnosed with "osteopenia," "low bone mass for age," or "osteoporosis." Thirty-nine percent of Hologic (Hologic, Inc., Bedford, MA) subjects and 30% of Lunar (GE Lunar, GE Madison, WI) subjects diagnosed with "osteoporosis" by T-score were reclassified as either "normal" or "osteopenia" when their Z-score was used. Substitution of DXA Z-scores for T-scores results in significant diagnostic disagreement and significantly fewer persons being diagnosed with low bone mineral density.

  7. A Modification to Angoff and Bookmarking Cut Scores to Account for the Imperfect Reliability of Test Scores (United States)

    MacCann, Robert G.


    It is shown that the Angoff and bookmarking cut scores are examples of true score equating that in the real world must be applied to observed scores. In the context of defining minimal competency, the percentage "failed" by such methods is a function of the length of the measuring instrument. It is argued that this length is largely…

  8. Examining the reliability of ADAS-Cog change scores. (United States)

    Grochowalski, Joseph H; Liu, Ying; Siedlecki, Karen L


    The purpose of this study was to estimate and examine ways to improve the reliability of change scores on the Alzheimer's Disease Assessment Scale, Cognitive Subtest (ADAS-Cog). The sample, provided by the Alzheimer's Disease Neuroimaging Initiative, included individuals with Alzheimer's disease (AD) (n = 153) and individuals with mild cognitive impairment (MCI) (n = 352). All participants were administered the ADAS-Cog at baseline and 1 year, and change scores were calculated as the difference in scores over the 1-year period. Three types of change score reliabilities were estimated using multivariate generalizability. Two methods to increase change score reliability were evaluated: reweighting the subtests of the scale and adding more subtests. Reliability of ADAS-Cog change scores over 1 year was low for both the AD sample (ranging from .53 to .64) and the MCI sample (.39 to .61). Reweighting the change scores from the AD sample improved reliability (.68 to .76), but lengthening provided no useful improvement for either sample. The MCI change scores had low reliability, even with reweighting and adding additional subtests. The ADAS-Cog scores had low reliability for measuring change. Researchers using the ADAS-Cog should estimate and report reliability for their use of the change scores. The ADAS-Cog change scores are not recommended for assessment of meaningful clinical change.

  9. Scoring functions for transcription factor binding site prediction

    Directory of Open Access Journals (Sweden)

    Friberg Markus


    Full Text Available Abstract Background Transcription factor binding site (TFBS prediction is a difficult problem, which requires a good scoring function to discriminate between real binding sites and background noise. Many scoring functions have been proposed in the literature, but it is difficult to assess their relative performance, because they are implemented in different software tools using different search methods and different TFBS representations. Results Here we compare how several scoring functions perform on both real and semi-simulated data sets in a common test environment. We have also developed two new scoring functions and included them in the comparison. The data sets are from the yeast (S. cerevisiae genome. Our new scoring function LLBG (least likely under the background model performs best in this study. It achieves the best average rank for the correct motifs. Scoring functions based on positional bias performed quite poorly in this study. Conclusion LLBG may provide an interesting alternative to current scoring functions for TFBS prediction.

    Borah Bijan J


    Full Text Available Abstract Background Medicare hospital Value-based purchasing (VBP program that links Medicare payments to quality of care will become effective from 2013. It is unclear whether specific hospital characteristics are associated with a hospital’s VBP score, and consequently incentive payments. The objective of the study was to assess the association of hospital characteristics with (i the mean VBP score, and (ii specific percentiles of the VBP score distribution. The secondary objective was to quantify the associations of hospital characteristics with the VBP score components: clinical process of care (CPC score and patient satisfaction score. Methods Observational analysis that used data from three sources: Medicare Hospital Compare Database, American Hospital Association 2010 Annual Survey and Medicare Impact File. The final study sample included 2,491 U.S. acute care hospitals eligible for the VBP program. The association of hospital characteristics with the mean VBP score and specific VBP score percentiles were assessed by ordinary least square (OLS regression and quantile regression (QR, respectively. Results VBP score had substantial variations, with mean score of 30 and 60 in the first and fourth quartiles of the VBP score distribution. For-profit status (vs. non-profit, smaller bed size (vs. 100–199 beds, East South Central region (vs. New England region and the report of specific CPC measures (discharge instructions, timely provision of antibiotics and beta blockers, and serum glucose controls in cardiac surgery patients were positively associated with mean VBP scores (p Conclusions Although hospitals serving the poor and the elderly are more likely to score lower under the VBP program, the correlation appears small. Profit status, geographic regions, number and type of CPC measures reported explain the most variation among scores.

  15. GOCS cohort: children's eating behavior scores and BMI. (United States)

    Sánchez, U; Weisstaub, G; Santos, J L; Corvalán, C; Uauy, R


    In Chile, approximately one in three children under 6 years of age reported overweight/obese, while one in four children in elementary school suffer from obesity. There is a paucity of population-based information on the influence of childhood eating behavior on anthropometric measures related to obesity. To assess the association between eating behavior scores and Body Mass Index (BMI) z-scores in 7-10-year-old Chilean children. We conducted a cross-sectional study in 1058 children aged 7-10 (51% girls) from the 'Growth and Obesity Chilean Cohort Study' (GOCS). Direct measures of weight and height were used to compute BMI z-scores according to World Health Organization (WHO) curves. Children were classified as normal weight (-1obese (⩾2 s.d.). Eating behavior scores were measured through the Child Eating Behavior Questionnaire (CEBQ), previously adapted and validated for Chilean children. Multiple linear regressions were carried out using BMI z-score as the outcome and eating behavior scores as explanatory variables. All models were adjusted by age and gender. BMI z-scores were positively associated with pro-intake scores in the subscales 'enjoyment of food', 'emotional overeating' and 'food responsiveness' (Peating' and 'food-fussiness' scores were negatively associated with BMI z-scores (Peating behavior scores and BMI z-scores in Chilean children, showing that BMI in 7-10-year-old Chilean children is positively associated with pro-intake eating behavior scores and negatively associated with anti-intake eating behavior scores. The identification of specific eating behaviors patterns related to obesity will provide important information for the implementation of prevention programs for this disease.

  17. IW-Scoring: an Integrative Weighted Scoring framework for annotating and prioritizing genetic variations in the noncoding genome. (United States)

    Wang, Jun; Dayem Ullah, Abu Z; Chelala, Claude


    The vast majority of germline and somatic variations occur in the noncoding part of the genome, only a small fraction of which are believed to be functional. From the tens of thousands of noncoding variations detectable in each genome, identifying and prioritizing driver candidates with putative functional significance is challenging. To address this, we implemented IW-Scoring, a new Integrative Weighted Scoring model to annotate and prioritise functionally relevant noncoding variations. We evaluate 11 scoring methods, and apply an unsupervised spectral approach for subsequent selective integration into two linear weighted functional scoring schemas for known and novel variations. IW-Scoring produces stable high-quality performance as the best predictors for three independent data sets. We demonstrate the robustness of IW-Scoring in identifying recurrent functional mutations in the TERT promoter, as well as disease SNPs in proximity to consensus motifs and with gene regulatory effects. Using follicular lymphoma as a paradigmatic cancer model, we apply IW-Scoring to locate 11 recurrently mutated noncoding regions in 14 follicular lymphoma genomes, and validate 9 of these regions in an extension cohort, including the promoter and enhancer regions of PAX5. Overall, IW-Scoring demonstrates greater versatility in identifying trait- and disease-associated noncoding variants.

    Cardiopulmonary exercise test (CPX) responses are strong predictors of outcomes in patients with heart failure. We recently developed a CPX score that integrated the additive prognostic information from CPX. The purpose of this study was to validate the score in a larger, independent sample of patients. A total of 2625 patients with heart failure underwent CPX and were followed for cardiovascular (CV) mortality and major CV events (death, transplantation, left ventricular assist device implantation). Net reclassification improvement (NRI) for the score and each of its components were determined at 3 years. The VE/VCO2 slope was the strongest predictor of risk and was attributed a relative weight of 7, with weighted scores for abnormal heart rate recovery, oxygen uptake efficiency slope, end-tidal CO2 pressure, and peak VO2 having scores of 5, 3, 3, and 2, respectively. A summed score of >15 was associated with an annual mortality rate of 12.2% and a relative risk >9 for total events, whereas a score of NRI compared with peak VO2 (category-free NRI, 0.61-0.77), and the score provided significant NRI above clinical risk factors for both CV events and mortality (NRI, 0.63 and 0.65 for CPX score compared with clinical variables alone). These results validate the application of a simple, integrated multivariable score based on readily available CPX responses.

    Credit scores are the most widely used instruments to assess whether or not a person is a financial risk. Credit scoring has been so successful that it has expanded beyond lending and into our everyday lives, even to inform how insurers evaluate our health. The pervasive application of credit scoring has outpaced knowledge about why credit scores are such useful indicators of individual behavior. Here we test if the same factors that lead to poor credit scores also lead to poor health. Following the Dunedin (New Zealand) Longitudinal Study cohort of 1,037 study members, we examined the association between credit scores and cardiovascular disease risk and the underlying factors that account for this association. We find that credit scores are negatively correlated with cardiovascular disease risk. Variation in household income was not sufficient to account for this association. Rather, individual differences in human capital factors—educational attainment, cognitive ability, and self-control—predicted both credit scores and cardiovascular disease risk and accounted for ∼45% of the correlation between credit scores and cardiovascular disease risk. Tracing human capital factors back to their childhood antecedents revealed that the characteristic attitudes, behaviors, and competencies children develop in their first decade of life account for a significant portion (∼22%) of the link between credit scores and cardiovascular disease risk at midlife. We discuss the implications of these findings for policy debates about data privacy, financial literacy, and early childhood interventions.

    Sinzobahamvya, Nicodème; Photiadis, Joachim; Kumpikaite, Daiva; Fink, Christoph; Blaschczok, Hedwig C; Brecher, Anne Marie; Asfour, Boulos


    Aristotle score is emerging as a reliable tool to measure surgical performance. We estimated the comprehensive Aristotle score for the Norwood procedure, correlated it with survival, and considered its impact on surgical management of hypoplastic left heart syndrome. Comprehensive Aristotle score was retrospectively calculated for 39 consecutive Norwood procedures performed from 2001 to 2004. Survival was estimated by the Kaplan-Meier method. The Aristotle scores ranged from 14.5 to 23.5 (mean, 19.12 +/- 2.52; median, 19.5). The score was 20 or greater in 44% (17 of 39) of cases. The most frequent patient-adjusted factors were aortic atresia (n = 16), interrupted aortic arch (n = 9), mechanical ventilation to treat cardiorespiratory failure (n = 19) and shock resolved at time of surgery (n = 13). Hospital mortality was 58.8% (10 of 17) in case of score of 20 or more and 9.1% (2 of 22) for score less than 20 (p = 0.0014). From 2003 on, all patients with a score less than 20 survived. Actuarial estimate of survival at 1 year is 56.2% +/- 7.9% and there have been no late deaths after 1 year. One-year survival is much lower (p = 0.001) for patients with scores of 20 or greater (29.4% +/- 11.05%) compared with those whose scores were less than 20 (77.3% +/- 8.9%). This study shows significant correlation of comprehensive Aristotle score with hospital mortality and late survival after Norwood palliation. It suggests that operative survival on the order of 90% may be achieved in patients with comprehensive complexity scores of less than 20. Efforts should be devoted to improve survival of high-risk patients (score > or = 20).

  1. Mobile health technology transforms injury severity scoring in South Africa. (United States)

    Spence, Richard Trafford; Zargaran, Eiman; Hameed, S Morad; Navsaria, Pradeep; Nicol, Andrew


    The burden of data collection associated with injury severity scoring has limited its application in areas of the world with the highest incidence of trauma. Since January 2014, electronic records (electronic Trauma Health Records [eTHRs]) replaced all handwritten records at the Groote Schuur Hospital Trauma Unit in South Africa. Data fields required for Glasgow Coma Scale, Revised Trauma Score, Kampala Trauma Score, Injury Severity Score (ISS), and Trauma Score-Injury Severity Score calculations are now prospectively collected. Fifteen months after implementation of eTHR, the injury severity scores were compared as predictors of mortality on three accounts: (1) ability to discriminate (area under receiver operating curve, ROC); (2) ability to calibrate (observed versus expected ratio, O/E); and (3) feasibility of data collection (rate of missing data). A total of 7460 admissions were recorded by eTHR from April 1, 2014 to July 7, 2015, including 770 severely injured patients (ISS > 15) and 950 operations. The mean age was 33.3 y (range 13-94), 77.6% were male, and the mechanism of injury was penetrating in 39.3% of cases. The cohort experienced a mortality rate of 2.5%. Patient reserve predictors required by the scores were 98.7% complete, physiological injury predictors were 95.1% complete, and anatomic injury predictors were 86.9% complete. The discrimination and calibration of Trauma Score-Injury Severity Score was superior for all admissions (ROC 0.9591 and O/E 1.01) and operatively managed patients (ROC 0.8427 and O/E 0.79). In the severely injured cohort, the discriminatory ability of Revised Trauma Score was superior (ROC 0.8315), but no score provided adequate calibration. Emerging mobile health technology enables reliable and sustainable injury severity scoring in a high-volume trauma center in South Africa. Copyright © 2016 Elsevier Inc. All rights reserved.

    We explored the association between Framingham risk score (FRS) and coronary artery calcium score (CACS) in asymptomatic Korean individuals. We retrospectively analyzed 2216 participants who underwent routine health screening and CACS using the 64-slice multidetector computed tomography between January 2010 and June 2014. Relationship between CACS and FRS, and factors associated with discrepancy between CACS and FRS were analyzed. CACS and FRS were positively correlated (p < 0.0001). However, in 3.7% of participants with low coronary event risk and high CACS, age, male gender, smoker, hypertension, total cholesterol, diabetes mellitus, and body mass index (BMI; ≥ 35) were associated with the discrepancy. In the diagnostic prediction model for discrepancy, the receiver operating characteristic curve including factors associated with FRS, diastolic blood pressure (≥ 75 mm Hg), diabetes mellitus, and BMI (≥ 35) showed that the area under the curve was 0.854 (95% confidence interval, 0.819–0.890), indicating good sensitivity. Diabetes mellitus or obesity (BMI ≥ 35) compensate for the weakness of FRS and may be potential indicators for application of CACS in asymptomatic Koreans with low coronary event risk.

  3. Optical Music Recognition for Scores Written in White Mensural Notation

    Directory of Open Access Journals (Sweden)

    Antonio Oliver


    Full Text Available An Optical Music Recognition (OMR system especially adapted for handwritten musical scores of the XVII-th and the early XVIII-th centuries written in white mensural notation is presented. The system performs a complete sequence of analysis stages: the input is the RGB image of the score to be analyzed and, after a preprocessing that returns a black and white image with corrected rotation, the staves are processed to return a score without staff lines; then, a music symbol processing stage isolates the music symbols contained in the score and, finally, the classification process starts to obtain the transcription in a suitable electronic format so that it can be stored or played. This work will help to preserve our cultural heritage keeping the musical information of the scores in a digital format that also gives the possibility to perform and distribute the original music contained in those scores.

  6. Improving personality facet scores with multidimensional computer adaptive testing

    DEFF Research Database (Denmark)

    Makransky, Guido; Mortensen, Erik Lykke; Glas, Cees A W


    Narrowly defined personality facet scores are commonly reported and used for making decisions in clinical and organizational settings. Although these facets are typically related, scoring is usually carried out for a single facet at a time. This method can be ineffective and time consuming when...... personality tests contain many highly correlated facets. This article investigates the possibility of increasing the precision of the NEO PI-R facet scores by scoring items with multidimensional item response theory and by efficiently administering and scoring items with multidimensional computer adaptive...... testing (MCAT). The increase in the precision of personality facet scores is obtained from exploiting the correlations between the facets.

    To determine the effect of a vacuum operator's experience on Apgar scores. A historical cohort study was conducted. All women who delivered by vacuum extraction between January 2003 and December 2007 at Songklanagarind Hospital were recruited. Vacuum operators were divided into two groups: staff doctors and residents. Comparisons of Apgar scores and rates of low Apgar scores (≤7) between the two groups were studied. A multivariate logistic regression analysis was used to control confounding variables for low Apgar scores. The percentages for the procedure performed by the staff doctors and residents were 76.9 and 23.1%. At 1 min, the rates of low Apgar scores in the staff and resident groups were 6.7 and 24.1% (pvacuum operator's experience was an independent risk factor for low Apgar scores. Improvement of the residency training program is mandatory.

  8. The Alvarado score for predicting acute appendicitis: a systematic review (United States)


    Background The Alvarado score can be used to stratify patients with symptoms of suspected appendicitis; the validity of the score in certain patient groups and at different cut points is still unclear. The aim of this study was to assess the discrimination (diagnostic accuracy) and calibration performance of the Alvarado score. Methods A systematic search of validation studies in Medline, Embase, DARE and The Cochrane library was performed up to April 2011. We assessed the diagnostic accuracy of the score at the two cut-off points: score of 5 (1 to 4 vs. 5 to 10) and score of 7 (1 to 6 vs. 7 to 10). Calibration was analysed across low (1 to 4), intermediate (5 to 6) and high (7 to 10) risk strata. The analysis focused on three sub-groups: men, women and children. Results Forty-two studies were included in the review. In terms of diagnostic accuracy, the cut-point of 5 was good at 'ruling out' admission for appendicitis (sensitivity 99% overall, 96% men, 99% woman, 99% children). At the cut-point of 7, recommended for 'ruling in' appendicitis and progression to surgery, the score performed poorly in each subgroup (specificity overall 81%, men 57%, woman 73%, children 76%). The Alvarado score is well calibrated in men across all risk strata (low RR 1.06, 95% CI 0.87 to 1.28; intermediate 1.09, 0.86 to 1.37 and high 1.02, 0.97 to 1.08). The score over-predicts the probability of appendicitis in children in the intermediate and high risk groups and in women across all risk strata. Conclusions The Alvarado score is a useful diagnostic 'rule out' score at a cut point of 5 for all patient groups. The score is well calibrated in men, inconsistent in children and over-predicts the probability of appendicitis in women across all strata of risk. PMID:22204638

    Erdem Öztürk


    Full Text Available Objective: Prostate cancer is the most common malignancy in men and the second cause of cancer-related mortality. Prostate biopsy and the Gleason score guide treatment decisions in prostate cancer. Several studies have investigated the correlation between biopsy scores and radical prostatectomy specimen scores. We also evaluated the correlation of Gleason scores of these specimens in our patient series. Materials and Methods: We retrospectively reviewed the data of 468 men who were diagnosed with prostate cancer and underwent radical prostatectomy between 2008 and 2017. Patients’ age, prostate-specific antigen levels at diagnosis, and prostate biopsy and radical prostatectomy specimen Gleason scores were recorded. Upgrading and downgrading were defined as increase or decrease of Gleason score of radical prostate specimen compared to Gleason score of prostate biopsy. Results: A total of 442 men diagnosed with prostate cancer were included in the study. The mean age of the patients was 62.62±6.26 years (44-84 years and mean prostate specific antigen level was 9.01±6.84 ng/mL (1.09-49 ng/mL. Prostate biopsy Gleason score was 7 in 27 (6.1% men. Radical prostatectomy specimen Gleason score was 7 in 62 (14% men. Gleason correlation was highest in the 240 patients (71.6% with score <7 and was lowest in the 31 (38.75% patients with score =7. Conclusion: This study demonstrated that the discordance rate between Gleason scores of prostate biopsy and radical prostatectomy specimens was 35.7%.

  11. Less is more: the design of early-warning scoring systems affects the speed and accuracy of scoring. (United States)

    Christofidis, Melany J; Hill, Andrew; Horswill, Mark S; Watson, Marcus O


    To evaluate the effect of early-warning scoring system design on the speed and accuracy of scoring. Despite the widespread implementation of early-warning scoring systems in hospitals, the speed and accuracy with which chart-users determine patients' early-warning scores has received minimal research attention. Within-subjects, with scoring-system design as the independent variable. Forty-seven novice chart-users were presented with realistic vital sign observations recorded on charts with three different scoring-system designs. The rows for recording individual vital sign scores were either: (1) grouped together beneath all of the vital sign rows; (2) separated, with each row presented immediately below the corresponding vital sign row; or (3) excluded altogether. Participants' response times and error rates for determining the overall scores were measured for 54 time-points per design. Data were collected in December 2012-January 2013. Contrary to predictions, participants responded fastest and made the fewest errors when using the chart design without individual vital sign scoring-rows. For the other two designs, participants were faster when the rows for scoring individual vital signs were separated (vs. grouped), but accuracy did not differ. For both of these designs, significantly more time-points were affected by scoring errors compared with adding errors. Finally, data for patients with more serious derangements yielded greater response times and error rates on all three charts. Early-warning scoring systems may be more effective without individual vital sign scoring-rows. Even when charts are designed by multi-disciplinary teams of human factors specialists and clinicians, empirical evaluations are essential. © 2015 John Wiley & Sons Ltd.

  12. Walk Score® and Transit Score® and walking in the multi-ethnic study of atherosclerosis. (United States)

    Hirsch, Jana A; Moore, Kari A; Evenson, Kelly R; Rodriguez, Daniel A; Diez Roux, Ana V


    Walk Score® and Transit Score® are open-source measures of the neighborhood built environment to support walking ("walkability") and access to transportation. To investigate associations of Street Smart Walk Score and Transit Score with self-reported transport and leisure walking using data from a large multicity and diverse population-based sample of adults. Data from a sample of 4552 residents of Baltimore MD, Chicago IL, Forsyth County NC, Los Angeles CA, New York NY, and St. Paul MN from the Multi-Ethnic Study of Atherosclerosis (2010-2012) were linked to Walk Score and Transit Score (collected in 2012). Logistic and linear regression models estimated ORs of not walking and mean differences in minutes walked, respectively, associated with continuous and categoric Walk Score and Transit Score. All analyses were conducted in 2012. After adjustment for site, key sociodemographic, and health variables, a higher Walk Score was associated with lower odds of not walking for transport and more minutes/week of transport walking. Compared to those in a "walker's paradise," lower categories of Walk Score were associated with a linear increase in odds of not transport walking and a decline in minutes of leisure walking. An increase in Transit Score was associated with lower odds of not transport walking or leisure walking, and additional minutes/week of leisure walking. Walk Score and Transit Score appear to be useful as measures of walkability in analyses of neighborhood effects. Copyright © 2013 American Journal of Preventive Medicine. Published by Elsevier Inc.

    No ideal and generally accepted prognostic factors and scoring systems exist to determine the prognosis of peritonitis associated with colonic perforation. This study was designed to investigate prognostic factors and evaluate the various scoring systems to allow identification of high-risk patients. Between 1996 and 2003, excluding iatrogenic and trauma cases, 26 consecutive patients underwent emergency operations for colorectal perforation and were selected for this retrospective study. Several clinical factors were analyzed as possible predictive factors, and APACHE II, SOFA, MPI, and MOF scores were calculated. The overall mortality was 26.9%. Compared with the survivors, non-survivors were found more frequently in Hinchey's stage III-IV, a low preoperative marker of pH, base excess (BE), and a low postoperative marker of white blood cell count, PaO2/FiO2 ratio, and renal output (24h). According to the logistic regression model, BE was a significant independent variable. Concerning the prognostic scoring systems, an APACHE II score of 19, a SOFA score of 8, an MPI score of 30, and an MOF score of 7 or more were significantly related to poor prognosis. Preoperative BE and postoperative white blood cell count were reliable prognostic factors and early classification using prognostic scoring systems at specific points in the disease process are useful to improve our understanding of the problems involved.

    Full Text Available The score test proposed by Rao (1947 has been widely used in the recent years for data analysis and model building because of its simplicity. However, at the time of its computation, it has been found that the value of the score test statistic becomes negative. Freedman (2007 discussed some of the theoretical reasons for this inconsistency of the score test and observed that the test was inconsistent when the observed Fisher information matrix was used rather than the expected Fisher information matrix. The present paper is an attempt to demonstrate the inconsistency of the score test in terms of the power function.

    Babak Nakhjavan-Shahraki


    Full Text Available Introduction: Rapid acute physiology score (RAPS and rapid emergency medicine score (REMS are two physiologic models for measuring injury severity in emergency settings. The present study was designed to compare the two models in outcome prediction of trauma patients presenting to emergency department (ED.Methods: In this prospective cross-sectional study, the two models of RAPS and REMS were compared regarding prediction of mortality and poor outcome (severe disability based on Glasgow outcome scale of trauma patients presenting to the EDs of 5 educational hospitals in Iran (Tehran, Tabriz, Urmia, Jahrom and Ilam from May to October 2016. The discriminatory power and calibration of the models were calculated and compared using STATA 11.Results: 2148 patients with the mean age of 39.50±17.27 years were studied (75.56% males. The area under the curve of REMS and RAPS in predicting in-hospital mortality were calculated to be 0.93 (95% CI: 0.92-0.95 and 0.899 (95% CI: 0.86-0.93, respectively (p=0.02. These measures were 0.92 (95% CI: 0.90-0.94 and 0.86 (95% CI: 0.83-0.90, respectively, regarding poor outcome (p=0.001. The optimum cut-off point in predicting outcome was found to be 3 for REMS model and 2 for RAPS model. The sensitivity and specificity of REMS and RAPS in the mentioned cut offs were 95.93 vs. 85.37 and 77.63 vs. 83.51, respectively, in predicting mortality. Calibration and overall performance of the two models were acceptable.Conclusion: The present study showed that adding age and level of arterial oxygen saturation to the variables included in RAPS model can increase its predictive value. Therefore, it seems that REMS could be used for predicting mortality and poor outcome of trauma patients in emergency settings

    Zhang, Xiaozhe; Dong, Xiaosong; Kantelhardt, Jan W; Li, Jing; Zhao, Long; Garcia, Carmen; Glos, Martin; Penzel, Thomas; Han, Fang


    The aim was to evaluate the inter-rater reliability in scoring sleep stages in two sleep labs in Berlin Germany and Beijing China. The subjects consist of polysomnography (PSGs) from 15 subjects in a German sleep laboratory, with 7 mild to moderate sleep apnea hypopnea syndrome (SAHS) patients and 8 healthy controls, and PSGs from 15 narcolepsy patients in a Chinese sleep laboratory. Five experienced technologists including two Chinese and three Germans without common training scored the PSGs following the 2007 AASM manual except the EEG signals included only two EEG leads (C3/A2 and C4/A1). Differences in inter-scorer agreement were analyzed based on epoch-by-epoch comparison by means of Cohen's κ, and quantitative sleep parameters by means of intra-class correlation coefficients. Inter-laboratory epoch-by-epoch agreement comparison between scorers from the two countries yielded a moderate agreement with a mean κ value of 0.57 for controls, 0.58 for SAHS, and 0.54 for narcolepsy. When compared with controls, the inter-scoring agreement is higher for wake and N3 stage scoring in SAHS and N1 and N3 scoring in narcolepsy (p < 0.05). The only sleep stage with lower scoring agreement in both SAHS (κ 0.69 vs. 0.79, p = 0.034) and narcolepsy (0.66 vs 0.79, p = 0.022) was stage REM. Inter-laboratory comparisons showed that the most common combinations of deviating scorings were N1 and N2, N2 and N3, and N1 and wake. A 6.5 % deviating scoring rate of wake and REM and a 13.4 % deviating scoring rate of N1 and REM indicated that inter-laboratory scoring in narcolepsy was about twice as in SAHS and controls confused. This was further confirmed by agreement analysis of quantitative parameters using intra-class correlation coefficients ICC(2,1) indicating REM sleep scoring agreement was lower in narcolepsy than in controls (p < 0.05). Low REM stage scoring agreement exists for narcoleptics and SAHS, indicating the necessity to study sleep stage scoring

  20. The APPLE Score - A Novel Score for the Prediction of Rhythm Outcomes after Repeat Catheter Ablation of Atrial Fibrillation.

    Jelena Kornej

    Full Text Available Arrhythmia recurrences after catheter ablation occur in up to 50% within one year but their prediction remains challenging. Recently, we developed a novel score for the prediction of rhythm outcomes after single AF ablation demonstrating superiority to other scores. The current study was performed to 1 prove the predictive value of the APPLE score in patients undergoing repeat AF ablation and 2 compare it with the CHADS2 and CHA2DS2-VASc scores.Rhythm outcome between 3-12 months after AF ablation were documented. The APPLE score (one point for Age >65 years, Persistent AF, imPaired eGFR (<60 ml/min/1.73m2, LA diameter ≥43 mm, EF <50% was calculated in every patient before procedure.379 consecutive patients from The Leipzig Heart Center AF Ablation Registry (60±10 years, 65% male, 70% paroxysmal AF undergoing repeat AF catheter ablation were included. Arrhythmia recurrences were observed in 133 patients (35%. While the CHADS2 (AUC 0.577, p = 0.037 and CHA2DS2-VASc scores (AUC 0.590, p = 0.015 demonstrated low predictive value, the APPLE score showed better prediction of arrhythmia recurrences (AUC 0.617, p = 0.002 than other scores (both p<0.001. Compared to patients with an APPLE score of 0, the risk (OR for arrhythmia recurrences was 2.9, 3.0 and 6.0 (all p<0.01 for APPLE scores 1, 2, or ≥3, respectively.The novel APPLE score is superior to the CHADS2 and CHA2DS2-VASc scores for prediction of rhythm outcomes after repeat AF catheter ablation. It may be helpful to identify patients with low, intermediate or high risk for recurrences after repeat procedure.

  2. Myelodysplastic syndromes: a scoring system with prognostic significance. (United States)

    Mufti, G J; Stevens, J R; Oscier, D G; Hamblin, T J; Machin, D


    141 patients with MDS were classified according to the FAB criteria and followed up for a period of 4-192 months. It was recognized that patients with RAEBT had a uniformly poor prognosis. However, there was a wide variation in survival among the other subgroups. A score of 1 was assigned to each of the following presenting haematological features: bone marrow blasts greater than or equal to 5%, platelets less than or equal to 100 X 10(9)/l, neutrophils less than or equal to 2.5 X 10(9)/l and Hb less than or equal to 10.0 g/dl. Therefore the score for each patient ranged between 0 and 4. There were no statistically significant differences between those patients who scored 0 or 1, or between those who scored 2 and 3. Therefore patients were put into three groups: Group A (score 0 or 1), Group B (score 2 or 3), Group C (score 4). The differences in survival between each of the three groups are highly significant (P less than 0.00001). This system further separates patients with RA, RAS, RAEB into good and bad prognostic groups. This study also confirms that deaths due to cytopenias are more common than those due to transformation to AML. The use of this scoring system in conjunction with the FAB criteria for MDS should serve as a prognostic tool on which to base treatment.

  3. Pain Scores Are Not Predictive of Pain Medication Utilization

    Directory of Open Access Journals (Sweden)

    Suzanne Galloway


    Full Text Available Objective. To compare Visual Analogue Scale (VAS scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery. Results. The mean age of the 219 participants was 54 (range19 to 94. We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA or RN administered (intravenous or oral medications. We also did not detect any association between the number of VAS scores recorded and mean pain scores. Conclusion. Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery. Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment. Our findings suggest that VAS scores are of limited utility for optimal pain control. Alternative or complimentary methods may improve pain management.

  14. MRI-based semiquantitative scoring of joint pathology in osteoarthritis. (United States)

    Guermazi, Ali; Roemer, Frank W; Haugen, Ida K; Crema, Michel D; Hayashi, Daichi


    The use of MRI techniques to investigate tissue pathology has become increasingly widespread in osteoarthritis (OA) research. Semiquantitative assessment of the joints by expert interpreters of MRI data is a powerful tool that can increase our understanding of the natural history of this complex disease. Several reliable and validated semiquantitative scoring systems now exist and have been applied to large-scale, multicentre, cross-sectional and longitudinal observational epidemiological studies. Such approaches have advanced our understanding of the associations of different tissue pathologies with pain and improved the definition of joint alterations that lead to disease progression. Semiquantitative MRI outcome measures have also been applied in several clinical trials in OA. Indeed, interest in MRI-based semiquantitative scoring systems has led to the development of several novel scoring systems that can be applied to different joints: a knee synovitis scoring system based on contrast-enhanced MRI; the MRI Osteoarthritis Knee Score (MOAKS); the Hip Osteoarthritis MRI Score (HOAMS); and the Oslo Hand Osteoarthritis MRI score (OHOA-MRI). Although these new scoring systems offer theoretical advantages over pre-existing systems, whether they offer actual superiority with regard to reliability, responsiveness and validity remains to be seen.

  9. Quasi-linear score for capturing heterogeneous structure in biomarkers. (United States)

    Omae, Katsuhiro; Komori, Osamu; Eguchi, Shinto


    Linear scores are widely used to predict dichotomous outcomes in biomedical studies because of their learnability and understandability. Such approaches, however, cannot be used to elucidate biodiversity when there is heterogeneous structure in target population. Our study was focused on describing intrinsic heterogeneity in predictions. Because heterogeneity can be captured by a clustering method, integrating different information from different clusters should yield better predictions. Accordingly, we developed a quasi-linear score, which effectively combines the linear scores of clustered markers. We extended the linear score to the quasi-linear score by a generalized average form, the Kolmogorov-Nagumo average. We observed that two shrinkage methods worked well: ridge shrinkage for estimating the quasi-linear score, and lasso shrinkage for selecting markers within each cluster. Simulation studies and applications to real data show that the proposed method has good predictive performance compared with existing methods. Heterogeneous structure is captured by a clustering method. Quasi-linear scores combine such heterogeneity and have a better predictive ability compared with linear scores.

  19. Multiple true-false items: a comparison of scoring algorithms. (United States)

    Lahner, Felicitas-Maria; Lörwald, Andrea Carolin; Bauer, Daniel; Nouns, Zineb Miriam; Krebs, René; Guttormsen, Sissel; Fischer, Martin R; Huwendiek, Sören


    Multiple true-false (MTF) items are a widely used supplement to the commonly used single-best answer (Type A) multiple choice format. However, an optimal scoring algorithm for MTF items has not yet been established, as existing studies yielded conflicting results. Therefore, this study analyzes two questions: What is the optimal scoring algorithm for MTF items regarding reliability, difficulty index and item discrimination? How do the psychometric characteristics of different scoring algorithms compare to those of Type A questions used in the same exams? We used data from 37 medical exams conducted in 2015 (998 MTF and 2163 Type A items overall). Using repeated measures analyses of variance (rANOVA), we compared reliability, difficulty and item discrimination of different scoring algorithms for MTF with four answer options and Type A. Scoring algorithms for MTF were dichotomous scoring (DS) and two partial credit scoring algorithms, PS 50 where examinees receive half a point if more than half of true/false ratings were marked correctly and one point if all were marked correctly, and PS 1/n where examinees receive a quarter of a point for every correct true/false rating. The two partial scoring algorithms showed significantly higher reliabilities (α PS1/n  = 0.75; α PS50  = 0.75; α DS  = 0.70, α A  = 0.72), which corresponds to fewer items needed for a reliability of 0.8 (n PS1/n  = 74; n PS50  = 75; n DS  = 103, n A  = 87), and higher discrimination indices (r PS1/n  = 0.33; r PS50  = 0.33; r DS  = 0.30; r A  = 0.28) than dichotomous scoring and Type A. Items scored with DS tend to be difficult (p DS  = 0.50), whereas items scored with PS 1/n become easy (p PS1/n  = 0.82). PS 50 and Type A cover the whole range, from easy to difficult items (p PS50  = 0.66; p A  = 0.73). Partial credit scoring leads to better psychometric results than dichotomous scoring. PS 50 covers the range from easy to difficult items better than PS 1/n

  20. New scoring schema for finding motifs in DNA Sequences

    Directory of Open Access Journals (Sweden)

    Nowzari-Dalini Abbas


    Full Text Available Abstract Background Pattern discovery in DNA sequences is one of the most fundamental problems in molecular biology with important applications in finding regulatory signals and transcription factor binding sites. An important task in this problem is to search (or predict known binding sites in a new DNA sequence. For this reason, all subsequences of the given DNA sequence are scored based on an scoring function and the prediction is done by selecting the best score. By assuming no dependency between binding site base positions, most of the available tools for known binding site prediction are designed. Recently Tomovic and Oakeley investigated the statistical basis for either a claim of dependence or independence, to determine whether such a claim is generally true, and they presented a scoring function for binding site prediction based on the dependency between binding site base positions. Our primary objective is to investigate the scoring functions which can be used in known binding site prediction based on the assumption of dependency or independency in binding site base positions. Results We propose a new scoring function based on the dependency between all positions in biding site base positions. This scoring function uses joint information content and mutual information as a measure of dependency between positions in transcription factor binding site. Our method for modeling dependencies is simply an extension of position independency methods. We evaluate our new scoring function on the real data sets extracted from JASPAR and TRANSFAC data bases, and compare the obtained results with two other well known scoring functions. Conclusion The results demonstrate that the new approach improves known binding site discovery and show that the joint information content and mutual information provide a better and more general criterion to investigate the relationships between positions in the TFBS. Our scoring function is formulated by simple

  1. Towards automated calculation of evidence-based clinical scores. (United States)

    Aakre, Christopher A; Dziadzko, Mikhail A; Herasevich, Vitaly


    To determine clinical scores important for automated calculation in the inpatient setting. A modified Delphi methodology was used to create consensus of important clinical scores for inpatient practice. A list of 176 externally validated clinical scores were identified from freely available internet-based services frequently used by clinicians. Scores were categorized based on pertinent specialty and a customized survey was created for each clinician specialty group. Clinicians were asked to rank each score based on importance of automated calculation to their clinical practice in three categories - "not important", "nice to have", or "very important". Surveys were solicited via specialty-group listserv over a 3-mo interval. Respondents must have been practicing physicians with more than 20% clinical time spent in the inpatient setting. Within each specialty, consensus was established for any clinical score with greater than 70% of responses in a single category and a minimum of 10 responses. Logistic regression was performed to determine predictors of automation importance. Seventy-nine divided by one hundred and forty-four (54.9%) surveys were completed and 72/144 (50%) surveys were completed by eligible respondents. Only the critical care and internal medicine specialties surpassed the 10-respondent threshold (14 respondents each). For internists, 2/110 (1.8%) of scores were "very important" and 73/110 (66.4%) were "nice to have". For intensivists, no scores were "very important" and 26/76 (34.2%) were "nice to have". Only the number of medical history (OR = 2.34; 95%CI: 1.26-4.67; P calculation. Future efforts towards score calculator automation should focus on technically feasible "nice to have" scores.

  3. Sensitivity, Specificity and Reliability of the RIPASA Score for Diagnosis of Acute Appendicitis in Relation to the Alvarado Score. (United States)

    Arroyo-Rangel, Celerino; Limón, Iván O; Vera, Ángel G; Guardiola, Pedro M; Sánchez-Valdivieso, Enrique A


    In order to avoid delay in the diagnosis of acute appendicitis and reduce the margin of error, the use of scales has been used. The aim of this study was to compare the effectiveness of the Alvarado and RIPASA scores in the clinical diagnosis of acute appendicitis and to correlate with the histopathological results. Prospective, longitudinal, analytical, comparative and observational study. Patients with abdominal pain syndrome suggestive of acute appendicitis and submitted to surgical intervention were included; the Alvarado and RIPASA scores were simultaneously applied. The pathology report was obtained and the efficacy of both scores for the diagnosis of acute appendicitis was compared. One hundred patients were included. It was shown that the RIPASA score demonstrated greater diagnostic accuracy compared to the Alvarado score, with sensitivity of 98,8% and specificity of 71,4% versus 90,7% and 64,3%, respectively. The RIPASA score showed an area under the curve of 0,88 and the Alvarado scale of 0,80. The RIPASA score is a more specific, convenient and accurate system than the Alvarado score for the Mexican population. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U.

    The goal of this study was to develop a simplified radiological score that could assess clinical disease severity in bronchiectasis. The Bronchiectasis Radiologically Indexed CT Score (BRICS) was devised based on a multivariable analysis of the Bhalla score and its ability in predicting clinical parameters of severity. The score was then externally validated in six centers in 302 patients. A total of 184 high-resolution CT scans were scored for the validation cohort. In a multiple logistic regression model, disease severity markers significantly associated with the Bhalla score were percent predicted FEV 1 , sputum purulence, and exacerbations requiring hospital admission. Components of the Bhalla score that were significantly associated with the disease severity markers were bronchial dilatation and number of bronchopulmonary segments with emphysema. The BRICS was developed with these two parameters. The receiver operating-characteristic curve values for BRICS in the derivation cohort were 0.79 for percent predicted FEV 1 , 0.71 for sputum purulence, and 0.75 for hospital admissions per year; these values were 0.81, 0.70, and 0.70, respectively, in the validation cohort. Sputum free neutrophil elastase activity was significantly elevated in the group with emphysema on CT imaging. A simplified CT scoring system can be used as an adjunct to clinical parameters to predict disease severity in patients with idiopathic and postinfective bronchiectasis.

    Full Text Available Mariam Fida,1 Salah Eldin Kassab2 1Department of Molecular Medicine, College of Medicine and Medical Sciences, Arabian Gulf University, Manama, Bahrain; 2Department of Medical Education, Faculty of Medicine, Suez Canal University, Ismailia, Egypt Purpose: The development of clinical problem-solving skills evolves over time and requires structured training and background knowledge. Computer-based case simulations (CCS have been used for teaching and assessment of clinical reasoning skills. However, previous studies examining the psychometric properties of CCS as an assessment tool have been controversial. Furthermore, studies reporting the integration of CCS into problem-based medical curricula have been limited. Methods: This study examined the psychometric properties of using CCS software (DxR Clinician for assessment of medical students (n=130 studying in a problem-based, integrated multisystem module (Unit IX during the academic year 2011–2012. Internal consistency reliability of CCS scores was calculated using Cronbach's alpha statistics. The relationships between students' scores in CCS components (clinical reasoning, diagnostic performance, and patient management and their scores in other examination tools at the end of the unit including multiple-choice questions, short-answer questions, objective structured clinical examination (OSCE, and real patient encounters were analyzed using stepwise hierarchical linear regression. Results: Internal consistency reliability of CCS scores was high (α=0.862. Inter-item correlations between students' scores in different CCS components and their scores in CCS and other test items were statistically significant. Regression analysis indicated that OSCE scores predicted 32.7% and 35.1% of the variance in clinical reasoning and patient management scores, respectively (P<0.01. Multiple-choice question scores, however, predicted only 15.4% of the variance in diagnostic performance scores (P<0.01, while

  9. External validation of the simple clinical score and the HOTEL score, two scores for predicting short-term mortality after admission to an acute medical unit. (United States)

    Stræde, Mia; Brabrand, Mikkel


    Clinical scores can be of aid to predict early mortality after admission to a medical admission unit. A developed scoring system needs to be externally validated to minimise the risk of the discriminatory power and calibration to be falsely elevated. We performed the present study with the objective of validating the Simple Clinical Score (SCS) and the HOTEL score, two existing risk stratification systems that predict mortality for medical patients based solely on clinical information, but not only vital signs. Pre-planned prospective observational cohort study. Danish 460-bed regional teaching hospital. We included 3046 consecutive patients from 2 October 2008 until 19 February 2009. 26 (0.9%) died within one calendar day and 196 (6.4%) died within 30 days. We calculated SCS for 1080 patients. We found an AUROC of 0.960 (95% confidence interval [CI], 0.932 to 0.988) for 24-hours mortality and 0.826 (95% CI, 0.774-0.879) for 30-day mortality, and goodness-of-fit test, χ(2) = 2.68 (10 degrees of freedom), P = 0.998 and χ(2) = 4.00, P = 0.947, respectively. We included 1470 patients when calculating the HOTEL score. Discriminatory power (AUROC) was 0.931 (95% CI, 0.901-0.962) for 24-hours mortality and goodness-of-fit test, χ(2) = 5.56 (10 degrees of freedom), P = 0.234. We find that both the SCS and HOTEL scores showed an excellent to outstanding ability in identifying patients at high risk of dying with good or acceptable precision.

  10. Targeted scoring criteria reduce variance in global impressions. (United States)

    Targum, Steven D; Busner, Joan; Young, Allan H


    This study examined the confounding effect of treatment emergent physical or psychic symptoms on clinical global impression (CGI) ratings in CNS trials and examined the benefit of targeted scoring criteria on clarifying ratings and reducing scoring variance. Twenty-four raters participating in an investigator meeting training session scored a series of scripted CGI scenarios that included treatment emergent symptoms. The addition of treatment emergent gastrointestinal (GI) symptoms or anxiety symptoms significantly changed the rating of clinical global improvement and caused a broad CGI-improvement (CGI-I) scoring variance reflecting scoring ambiguity amongst these raters. Re-rating after a presentation of well-defined criteria that addressed these scoring issues narrowed the variance and significantly improved inter-rater reliability. It is clear that CNS trials must define scoring criteria for global ratings prior to the initiation of a study to assure ratings consistency. The actual definition of global must be study-specific and may depend upon the targeted symptoms of interest and mechanism of drug action. The targeted criteria that define global must be included in all published reports about the trial.

  11. Developing optimal non-linear scoring function for protein design. (United States)

    Hu, Changyu; Li, Xiang; Liang, Jie


    Motivation. Protein design aims to identify sequences compatible with a given protein fold but incompatible to any alternative folds. To select the correct sequences and to guide the search process, a design scoring function is critically important. Such a scoring function should be able to characterize the global fitness landscape of many proteins simultaneously. To find optimal design scoring functions, we introduce two geometric views and propose a formulation using a mixture of non-linear Gaussian kernel functions. We aim to solve a simplified protein sequence design problem. Our goal is to distinguish each native sequence for a major portion of representative protein structures from a large number of alternative decoy sequences, each a fragment from proteins of different folds. Our scoring function discriminates perfectly a set of 440 native proteins from 14 million sequence decoys. We show that no linear scoring function can succeed in this task. In a blind test of unrelated proteins, our scoring function misclassfies only 13 native proteins out of 194. This compares favorably with about three-four times more misclassifications when optimal linear functions reported in the literature are used. We also discuss how to develop protein folding scoring function.

  12. Does the Aristotle Score predict outcome in congenital heart surgery? (United States)

    Kang, Nicholas; Tsang, Victor T; Elliott, Martin J; de Leval, Marc R; Cole, Timothy J


    The Aristotle Score has been proposed as a measure of 'complexity' in congenital heart surgery, and a tool for comparing performance amongst different centres. To date, however, it remains unvalidated. We examined whether the Basic Aristotle Score was a useful predictor of mortality following open-heart surgery, and compared it to the Risk Adjustment in Congenital Heart Surgery (RACHS-1) system. We also examined the ability of the Aristotle Score to measure performance. The Basic Aristotle Score and RACHS-1 risk categories were assigned retrospectively to 1085 operations involving cardiopulmonary bypass in children less than 18 years of age. Multiple logistic regression analysis was used to determine the significance of the Aristotle Score and RACHS-1 category as independent predictors of in-hospital mortality. Operative performance was calculated using the Aristotle equation: performance = complexity x survival. Multiple logistic regression identified RACHS-1 category to be a powerful predictor of mortality (Wald 17.7, p Aristotle Score was only weakly associated with mortality (Wald 4.8, p = 0.03). Age at operation and bypass time were also highly significant predictors of postoperative death (Wald 13.7 and 33.8, respectively, p Aristotle Score was only weakly associated with postoperative mortality in this series. Operative performance appeared to be inflated by the fact that the overall complexity of cases was relatively high in this series. An alternative equation (performance = complexity/mortality) is proposed as a fairer and more logical method of risk-adjustment.

  13. Development of a new Knee Society scoring system. (United States)

    Noble, Philip C; Scuderi, Giles R; Brekke, Adam C; Sikorskii, Alla; Benjamin, James B; Lonner, Jess H; Chadha, Priya; Daylamani, Daniel A; Scott, W Norman; Bourne, Robert B


    The Knee Society Clinical Rating System was developed in 1989 and has been widely adopted. However, with the increased demand for TKA, there is a need for a new, validated scoring system to better characterize the expectations, satisfaction, and physical activities of the younger, more diverse population of TKA patients. We developed and validated a new Knee Society Scoring System. We developed the new knee scoring system in two stages. Initially, a comprehensive survey of activities was developed and administered to 101 unilateral TKA patients (53 women, 48 men). A prototype knee scoring instrument was developed from the responses to the survey and administered to 497 patients (204 men, 293 women; 243 postoperatively, 254 preoperatively) at 15 medical institutions within the United States and Canada. Objective and subjective data were analyzed using standard statistical and psychometric procedures and compared to the Knee Injury and Osteoarthritis Score and SF-12 scores for validation. Based on this analysis, minor modifications led to the new Knee Society Scoring System. We found the new Knee Society Scoring System to be broadly applicable and to accurately characterize patient outcomes after TKA. Statistical analysis confirmed the internal consistency, construct and convergent validity, and reliability of the separate subscale measures. The new Knee Society Scoring System is a validated instrument based on surgeon- and patient-generated data, adapted to the diverse lifestyles and activities of contemporary patients with TKA. This assessment tool allows surgeons to appreciate differences in the priorities of individual patients and the interplay among function, expectation, symptoms, and satisfaction after TKA.

  15. Timing of Emergency Medicine Student Evaluation Does Not Affect Scoring. (United States)

    Hiller, Katherine M; Waterbrook, Anna; Waters, Kristina


    Evaluation of medical students rotating through the emergency department (ED) is an important formative and summative assessment method. Intuitively, delaying evaluation should affect the reliability of this assessment method, however, the effect of evaluation timing on scoring is unknown. A quality-improvement project evaluating the timing of end-of-shift ED evaluations at the University of Arizona was performed to determine whether delay in evaluation affected the score. End-of-shift ED evaluations completed on behalf of fourth-year medical students from July 2012 to March 2013 were reviewed. Forty-seven students were evaluated 547 times by 46 residents and attendings. Evaluation scores were means of anchored Likert scales (1-5) for the domains of energy/interest, fund of knowledge, judgment/problem-solving ability, clinical skills, personal effectiveness, and systems-based practice. Date of shift, date of evaluation, and score were collected. Linear regression was performed to determine whether timing of the evaluation had an effect on evaluation score. Data were complete for 477 of 547 evaluations (87.2%). Mean evaluation score was 4.1 (range 2.3-5, standard deviation 0.62). Evaluations took a mean of 8.5 days (median 4 days, range 0-59 days, standard deviation 9.77 days) to complete. Delay in evaluation had no significant effect on score (p = 0.983). The evaluation score was not affected by timing of the evaluation. Variance in scores was similar for both immediate and delayed evaluations. Considerable amounts of time and energy are expended tracking down delayed evaluations. This activity does not impact a student's final grade. Copyright © 2016 Elsevier Inc. All rights reserved.

  16. Integrating Seasonal Oscillations into Basel II Behavioural Scoring Models

    Directory of Open Access Journals (Sweden)

    Goran Klepac


    Full Text Available The article introduces a new methodology of temporal influence measurement (seasonal oscillations, temporal patterns for behavioural scoring development purposes. The paper shows how significant temporal variables can be recognised and then integrated into the behavioural scoring models in order to improve model performance. Behavioural scoring models are integral parts of the Basel II standard on Internal Ratings-Based Approaches (IRB. The IRB approach much more precisely reflects individual risk bank profile.A solution of the problem of how to analyze and integrate macroeconomic and microeconomic factors represented in time series into behavioural scorecard models will be shown in the paper by using the REF II model.


    Comrey, A L; Duffy, K E


    The Eysenck Personality Inventory, the Cattell 16 PF Inventory, and the Comrey Personality Inventory were administered to 272 volunteers. Eysenck and Cattell factor scores were correlated with scores over homogeneous item groups (FHIDs) which define the Comrey test factors. This matrix was factor analyzed to relate the Eysenck and Cattell factor scores to the factor structure underlying the Comrey test. The Eysenck Neuroticism, Comrey Neuroticism, and Cattell second-order Anxiety factors appeared to match. The Eysenck Introversion and the Comrey Shyness factors also matched. The 16 Cattell primary factors overlapped but did not match with the Comrey factors.

  18. Thrombotic risk assessment in APS: the Global APS Score (GAPSS). (United States)

    Sciascia, S; Bertolaccini, M L


    Recently, we developed a risk score for antiphospholipid syndrome (APS) (Global APS Score or GAPSS). This score derived from the combination of independent risk factors for thrombosis and pregnancy loss, taking into account the antiphospholipid antibodies (aPL) profile (criteria and non-criteria aPL), the conventional cardiovascular risk factors, and the autoimmune antibodies profile. We demonstrate that risk profile in APS can be successfully assessed, suggesting that GAPSS can be a potential quantitative marker of APS-related clinical manifestations. © The Author(s) 2014 Reprints and permissions:

  20. Investigating kindergarteners' number sense and self-regulation scores in relation to their mathematics and Turkish scores in middle school (United States)

    İvrendi, Asiye


    Number sense and self-regulation are considered foundational skills for later school learning. This study aimed to investigate the predictive power of kindergarten children's number sense and self-regulation scores on their mathematics and Turkish language examination scores in the 5th and 6th grades. The participants in this study were 5th grade ( n = 46) and 6th grade ( n = 28) students, whose number sense and self-regulation skills were measured when they were in kindergarten in 2009 and 2010. Data were analyzed through multiple regression. The results showed positive and mid-level correlations. The children's kindergarten number sense and self-regulation scores significantly predicted their 5th and 6th grade mathematics and Turkish language examination scores. Self-regulation was the stronger predictor of mathematics scores, whereas number sense scores were the better predictor of Turkish language examination scores. The findings from this study provide further evidence as to the critical role of children's early skills in middle school mathematics and language achievement.

  1. Predictive Value of Glasgow Coma Score and Full Outline of Unresponsiveness Score on the Outcome of Multiple Trauma Patients. (United States)

    Baratloo, Alireza; Shokravi, Masumeh; Safari, Saeed; Aziz, Awat Kamal


    The Full Outline of Unresponsiveness (FOUR) score was developed to compensate for the limitations of Glasgow coma score (GCS) in recent years. This study aimed to assess the predictive value of GCS and FOUR score on the outcome of multiple trauma patients admitted to the emergency department. The present prospective cross-sectional study was conducted on multiple trauma patients admitted to the emergency department. GCS and FOUR scores were evaluated at the time of admission and at the sixth and twelfth hours after admission. Then the receiver operating characteristic (ROC) curve, sensitivity, specificity, as well as positive and negative predictive value of GCS and FOUR score were evaluated to predict patients' outcome. Patients' outcome was divided into discharge with and without a medical injury (motor deficit, coma or death). Finally, 89 patients were studied. Sensitivity and specificity of GCS in predicting adverse outcome (motor deficit, coma or death) were 84.2% and 88.6% at the time of admission, 89.5% and 95.4% at the sixth hour and 89.5% and 91.5% at the twelfth hour, respectively. These values for the FOUR score were 86.9% and 88.4% at the time of admission, 89.5% and 100% at the sixth hour and 89.5% and 94.4% at the twelfth hour, respectively. Findings of this study indicate that the predictive value of FOUR score and GCS on the outcome of multiple trauma patients admitted to the emergency department is similar.

    We compared children who were positive for Ebola virus disease (EVD) with those who were negative to derive a pediatric EVD predictor (PEP) score. We collected data on all children <13 years of age admitted to 11 Ebola holding units in Sierra Leone during August 2014–March 2015 and performed multivariable logistic regression. Among 1,054 children, 309 (29%) were EVD positive and 697 (66%) EVD negative, with 48 (5%) missing. Contact history, conjunctivitis, and age were the strongest positive predictors for EVD. The PEP score had an area under receiver operating characteristics curve of 0.80. A PEP score of 7/10 was 92% specific and 44% sensitive; 3/10 was 30% specific, 94% sensitive. The PEP score could correctly classify 79%–90% of children and could be used to facilitate triage into risk categories, depending on the sensitivity or specificity required. PMID:29350145

  5. Evaluation of a Lameness Scoring System for Dairy Cows

    DEFF Research Database (Denmark)

    Thomsen, P T; Munksgaard, L; Tøgersen, F A


    Lameness is a major problem in dairy production both in terms of reduced production and compromised animal welfare. A 5-point lameness scoring system was developed based on previously published systems, but optimized for use under field conditions. The scoring system included the words "in most...... cases" in the descriptions of the clinical signs evaluated. This was done to avoid a situation in which cows might not fit into any of the categories. Additionally, a number of clinical signs used in other lameness scoring systems, considered of less importance in relation to lameness, were not included....... Only clinical signs were included that could easily be assessed within a few seconds from a distance. The scoring system was evaluated with intra-and interobserver agreement using kappa statistics. The evaluation was done before and after training 5 observers. Weighted kappa values ranged from 0...

  8. Scoring of nonmetric cranial traits: a methodological approach. (United States)

    Gualdi-Russo, E; Tasca, M A; Brasili, P


    The purpose of the present study was to analyse the replicability of the scoring of discontinuous traits. This was assessed on a sample of 100 skulls from the Frassetto collection (Dipartimento di Biologia Evoluzionistica Sperimentale of Bologna University) analysed through intraobserver comparisons: the discontinuous traits were determined on the same skulls and by the same observer on 3 separate occasions. The scoring was also assessed through interobserver comparisons: 3 different observers performed an independent survey on the same skulls. The results show that there were no significant differences in the discontinuous trait frequencies between the 3 different scorings by the same observer, but there were sometimes significant differences between different observers. Caution should thus be taken in applying the frequencies of these traits to population research. After an indispensable control of material conditions (subject age included), consideration must be given to standardisation procedures between observers, otherwise this may be an additional source of variability in cranial discontinuous trait scoring.

  12. A Human Capital Model of Educational Test Scores

    DEFF Research Database (Denmark)

    McIntosh, James; D. Munk, Martin

    Latent class Poisson count models are used to analyze a sample of Danish test score results from a cohort of individuals born in 1954-55 and tested in 1968. The procedure takes account of unobservable effects as well as excessive zeros in the data. The bulk of unobservable effects are uncorrelated...... with observable parental attributes and, thus, are environmental rather than genetic in origin. We show that the test scores measure manifest or measured ability as it has evolved over the life of the respondent and is, thus, more a product of the human capital formation process than some latent or fundamental...... measure of pure cognitive ability. We find that variables which are not closely associated with traditional notions of intelligence explain a significant proportion of the variation in test scores. This adds to the complexity of interpreting test scores and suggests that school culture, attitudes...

  16. Environmental structure and competitive scoring advantages in team competitions (United States)

    Merritt, Sears; Clauset, Aaron


    In most professional sports, playing field structure is kept neutral so that scoring imbalances may be attributed to differences in team skill. It thus remains unknown what impact environmental heterogeneities can have on scoring dynamics or competitive advantages. Applying a novel generative model of scoring dynamics to roughly 10 million team competitions drawn from an online game, we quantify the relationship between the structure within a competition and its scoring dynamics, while controlling the impact of chance. Despite wide structural variations, we observe a common three-phase pattern in the tempo of events. Tempo and balance are highly predictable from a competition's structural features alone and teams exploit environmental heterogeneities for sustained competitive advantage. Surprisingly, the most balanced competitions are associated with specific environmental heterogeneities, not from equally skilled teams. These results shed new light on the design principles of balanced competition, and illustrate the potential of online game data for investigating social dynamics and competition.

  17. Exact Score Distribution Computation for Similarity Searches in Ontologies (United States)

    Schulz, Marcel H.; Köhler, Sebastian; Bauer, Sebastian; Vingron, Martin; Robinson, Peter N.

    Semantic similarity searches in ontologies are an important component of many bioinformatic algorithms, e.g., protein function prediction with the Gene Ontology. In this paper we consider the exact computation of score distributions for similarity searches in ontologies, and introduce a simple null hypothesis which can be used to compute a P-value for the statistical significance of similarity scores. We concentrate on measures based on Resnik’s definition of ontological similarity. A new algorithm is proposed that collapses subgraphs of the ontology graph and thereby allows fast score distribution computation. The new algorithm is several orders of magnitude faster than the naive approach, as we demonstrate by computing score distributions for similarity searches in the Human Phenotype Ontology.

  3. Towards a contemporary, comprehensive scoring system for determining technical outcomes of hybrid percutaneous chronic total occlusion treatment: The RECHARGE score. (United States)

    Maeremans, Joren; Spratt, James C; Knaapen, Paul; Walsh, Simon; Agostoni, Pierfrancesco; Wilson, William; Avran, Alexandre; Faurie, Benjamin; Bressollette, Erwan; Kayaert, Peter; Bagnall, Alan J; Smith, Dave; McEntegart, Margaret B; Smith, William H T; Kelly, Paul; Irving, John; Smith, Elliot J; Strange, Julian W; Dens, Jo


    This study sought to create a contemporary scoring tool to predict technical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) from patients treated by hybrid operators with differing experience levels. Current scoring systems need regular updating to cope with the positive evolutions regarding materials, techniques, and outcomes, while at the same time being applicable for a broad range of operators. Clinical and angiographic characteristics from 880 CTO-PCIs included in the REgistry of CrossBoss and Hybrid procedures in FrAnce, the NetheRlands, BelGium and UnitEd Kingdom (RECHARGE) were analyzed by using a derivation and validation set (2:1 ratio). Variables significantly associated with technical failure in the multivariable analysis were incorporated in the score. Subsequently, the discriminatory capacity was assessed and the validation set was used to compare with the J-CTO score and PROGRESS scores. Technical success in the derivation and validation sets was 83% and 85%, respectively. Multivariate analysis identified six parameters associated with technical failure: blunt stump (beta coefficient (b) = 1.014); calcification (b = 0.908); tortuosity ≥45° (b = 0.964); lesion length 20 mm (b = 0.556); diseased distal landing zone (b = 0.794), and previous bypass graft on CTO vessel (b = 0.833). Score variables remained significant after bootstrapping. The RECHARGE score showed better discriminatory capacity in both sets (area-under-the-curve (AUC) = 0.783 and 0.711), compared to the J-CTO (AUC = 0.676) and PROGRESS (AUC = 0.608) scores. The RECHARGE score is a novel, easy-to-use tool for assessing the risk for technical failure in hybrid CTO-PCI and has the potential to perform well for a broad community of operators. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

  4. Graz Critical Limb Ischemia Score: A Risk Score for Critical Limb Ischemia in Peripheral Arterial Occlusive Disease. (United States)

    Gary, Thomas; Belaj, Klara; Hafner, Franz; Eller, Philipp; Rief, Peter; Hackl, Gerald; Brodmann, Marianne


    Critical limb ischemia (CLI), a frequently encountered disorder, is associated with a high rate of limb amputation and mortality. To identify patients at high risk for CLI, we developed a simple risk score for peripheral arterial occlusive disease (PAOD).In our cross-sectional study, we first evaluated 1000 consecutive PAOD patients treated at our institution from 2005 to 2007, documenting clinical symptoms, comorbidities, and concomitant medication. We calculated odds ratios (OR) in a binary logistic regression model to find possible risk factors for CLI. We then verified the score in a second step that included the 1124 PAOD patients we treated between 2007 and 2011.In the first patient group, the greatest risk factors for CLI were age ≥75 years (OR 2.0), type 2 diabetes (OR 3.1), prior myocardial infarction (OR 2.5), and therapy with low molecular weight heparins (2.8). We scored 1 point for each of those conditions. One point was given for age between 65 and 75 years (OR 1.6) as well as for therapy with cardiac glycosides (OR 1.9) or loop diuretic therapy (OR 1.5). As statin therapy was protective for CLI with an OR of 0.5, we subtracted 1 point for those patients.In the second group, we could prove that frequency of CLI was significantly higher in patients with a high CLI score. The score correlated well with inflammatory parameters (c-reactive protein and fibrinogen). We were also able to define 3 different risk groups for low (score -1 to 1), intermediate (score 2-4), and high CLI risk (score >4).We developed a simple risk stratification scheme that is based on conditions that can be easily assessed from the medical history, without any laboratory parameters. This score should help to identify PAOD patients at high risk for CLI.

  5. Evaluation of probabilistic forecasts with the scoringRules package (United States)

    Jordan, Alexander; Krüger, Fabian; Lerch, Sebastian


    Over the last decades probabilistic forecasts in the form of predictive distributions have become popular in many scientific disciplines. With the proliferation of probabilistic models arises the need for decision-theoretically principled tools to evaluate the appropriateness of models and forecasts in a generalized way in order to better understand sources of prediction errors and to improve the models. Proper scoring rules are functions S(F,y) which evaluate the accuracy of a forecast distribution F , given that an outcome y was observed. In coherence with decision-theoretical principles they allow to compare alternative models, a crucial ability given the variety of theories, data sources and statistical specifications that is available in many situations. This contribution presents the software package scoringRules for the statistical programming language R, which provides functions to compute popular scoring rules such as the continuous ranked probability score for a variety of distributions F that come up in applied work. For univariate variables, two main classes are parametric distributions like normal, t, or gamma distributions, and distributions that are not known analytically, but are indirectly described through a sample of simulation draws. For example, ensemble weather forecasts take this form. The scoringRules package aims to be a convenient dictionary-like reference for computing scoring rules. We offer state of the art implementations of several known (but not routinely applied) formulas, and implement closed-form expressions that were previously unavailable. Whenever more than one implementation variant exists, we offer statistically principled default choices. Recent developments include the addition of scoring rules to evaluate multivariate forecast distributions. The use of the scoringRules package is illustrated in an example on post-processing ensemble forecasts of temperature.

    Credit scoring allows for the credit risk assessment of bank customers. A single scoring model (scorecard) can be developed for the entire customer population, e.g. using logistic regression. However, it is often expected that segmentation, i.e. dividing the population into several groups and building separate scorecards for them, will improve the model performance. The most common statistical methods for segmentation are the two-step approaches, where logistic regression follows Classificati...

  10. dBBQs: dataBase of Bacterial Quality scores. (United States)

    Wanchai, Visanu; Patumcharoenpol, Preecha; Nookaew, Intawat; Ussery, David


    It is well-known that genome sequencing technologies are becoming significantly cheaper and faster. As a result of this, the exponential growth in sequencing data in public databases allows us to explore ever growing large collections of genome sequences. However, it is less known that the majority of available sequenced genome sequences in public databases are not complete, drafts of varying qualities. We have calculated quality scores for around 100,000 bacterial genomes from all major genome repositories and put them in a fast and easy-to-use database. Prokaryotic genomic data from all sources were collected and combined to make a non-redundant set of bacterial genomes. The genome quality score for each was calculated by four different measurements: assembly quality, number of rRNA and tRNA genes, and the occurrence of conserved functional domains. The dataBase of Bacterial Quality scores (dBBQs) was designed to store and retrieve quality scores. It offers fast searching and download features which the result can be used for further analysis. In addition, the search results are shown in interactive JavaScript chart framework using DC.js. The analysis of quality scores across major public genome databases find that around 68% of the genomes are of acceptable quality for many uses. dBBQs (available at ) provides genome quality scores for all available prokaryotic genome sequences with a user-friendly Web-interface. These scores can be used as cut-offs to get a high-quality set of genomes for testing bioinformatics tools or improving the analysis. Moreover, all data of the four measurements that were combined to make the quality score for each genome, which can potentially be used for further analysis. dBBQs will be updated regularly and is freely use for non-commercial purpose.

  11. Genetic evaluation of hip score in UK Labrador Retrievers.

    Directory of Open Access Journals (Sweden)

    Thomas W Lewis


    Full Text Available Hip dysplasia is an important and complex genetic disease in dogs with both genetic and environmental influences. Since the osteoarthritis that develops is irreversible the only way to improve welfare, through reducing the prevalence, is through genetic selection. This study aimed to evaluate the progress of selection against hip dysplasia, to quantify potential improvements in the response to selection via use of genetic information and increases in selection intensity, and to prepare for public provision of estimated breeding values (EBV for hip dysplasia in the UK. Data consisted of 25,243 single records of hip scores of Labrador Retrievers between one and four years old, from radiographs evaluated between 2000 and 2007 as part of the British Veterinary Association (BVA hip score scheme. A natural logarithm transformation was applied to improve normality and linear mixed models were evaluated using ASREML. Genetic correlations between left and right scores, and total hip scores at one, two and three years of age were found to be close to one, endorsing analysis of total hip score in dogs aged one to three as an appropriate approach. A heritability of 0.35±0.016 and small but significant litter effect (0.07±0.009 were estimated. The observed trends in both mean hip score and mean EBV over year of birth indicate that a small genetic improvement has been taking place, approximately equivalent to avoiding those dogs with the worst 15% of scores. Deterministic analysis supported by simulations showed that a 19% greater response could be achieved using EBV compared to phenotype through increases in accuracy alone. This study establishes that consistent but slow genetic improvement in the hip score of UK Labrador Retrievers has been achieved over the previous decade, and demonstrates that progress may be easily enhanced through the use of EBVs and more intense selection.

As a group, the patient collages had fewer cuttings, tended to lack an overall balance and central theme, and contained fewer pictures of people and more of animals. The results are consistent with those reported by other researchers as well as with general clinical experience, and as such, lend support to the construct validity of the scoring system.

  14. Smartphone Restriction and its Effect on Subjective Withdrawal Related Scores


    Aarestad, Sarah Helene; Eide, Tine Almenning


    Smartphone overuse is associated with a number of negative consequences for the individual and the environment. In the right end of the distribution of smartphone usage, concepts such as smartphone addiction seem warranted. An area that so far lacks research concerns the effect of smartphone restriction generally and specifically on subjective withdrawal related scores across different degrees of smartphone usage. The present study examined withdrawal related scores on the Smartphone Withdraw...

  16. Supersparse Linear Integer Models for Optimized Medical Scoring Systems


    Ustun, Berk; Rudin, Cynthia


    Scoring systems are linear classification models that only require users to add, subtract and multiply a few small numbers in order to make a prediction. These models are in widespread use by the medical community, but are difficult to learn from data because they need to be accurate and sparse, have coprime integer coefficients, and satisfy multiple operational constraints. We present a new method for creating data-driven scoring systems called a Supersparse Linear Integer Model (SLIM). SLIM...

  17. Is MELD really the definitive score for liver allocation? (United States)

    Lladó, Laura; Figueras, Juan; Memba, Roberto; Xiol, Xavier; Baliellas, Carmen; Vázquez, Santiago; Ramos, Emilio; Torras, Jaume; Rafecas, Antoni; Fabregat, Juan; Lama, Carmen; Jaurrieta, Eduardo


    The best system for organ allocation is still a controversial issue. The aim of this study was to study the accuracy of four different scores to predict mortality on the waiting list and, thus, their usefulness to determine organ allocation. We retrospectively compared two groups of patients, those who died on waiting list (group D) and those who successfully underwent transplantation (group T) during the same time period. Four scores, at the time of entering the waiting list and just before liver transplantation or death, were evaluated. The evaluated scores were as follows: (1) the Child-Pugh classification; (2) the Model for End-Stage Liver Disease (MELD) score; (3) the Freeman scale; and (4) the Guardiola et al index. The mortality rate on waiting list was 15.9%. All studied scores, except Freeman scale, were higher in group D at the time of entrance on waiting list (MELD, 17.4 +/- 8 v 12.3 +/- 6, P = .02; Child, 9.9 +/- 2 v 7.7 +/- 2, P = .002; Freeman, 9.7 +/- 4 v 7.3 +/- 3.9, P = .09; Guardiola, 2.6 +/- 0.9 v 1.7 +/- 0.7, P = .001). C-statistics of all scores were similar and in all cases lower than 0.8 (MELD, 0.75; Child, 0.78; Freeman, 0.65; Guardiola, 0.79). None of the studied scores have an excellent accuracy to predict prognosis of patients on waiting list, mainly in case of populations with high proportion of hepatocellular carcinoma. Although the MELD score is rapidly available, standardized, and objective, it does not reflect the severity of patients with cancer or metabolic disorders.

  18. Formation of borrower’s bank credit scoring integrated model

    Directory of Open Access Journals (Sweden)

    O.V. Lysenok


    Full Text Available The article proposes the borrower’s bank credit scoring model that is of particular relevance in an unstable world and Ukrainian financial markets. The essence of this integrated model is the consistent definition of indicators, which analyze the financial and economic situation and development of scoring that allows to calculate overall index, that is, the integral factor of credit scoring level of the bank to calculate which one uses the formed set of factors characterizing riskiness, profitability and liquidity of the banking institution. The author determines the factors according to their functional purpose; the former ones are divided into four groups: capital adequacy, loan portfolio quality, profitability and liquidity. Each group consists of four indicators; each indicator is assigned thresholds to determine the appropriate credit scoring level of the bank for one or another direction. The higher is the value of the integral factor, the more efficient and less risky is the financial and economic activity of banks and the higher is their credit scoring level. The study concludes that the proposed model for bank credit scoring differs with its transparency and clarity due to use in its implementation only public information. The disadvantages include the presence of the subjective factor in assigning a certain number of points based on expert and normative methods.

  19. Assessing Hourly Precipitation Forecast Skill with the Fractions Skill Score (United States)

    Zhao, Bin; Zhang, Bo


    Statistical methods for category (yes/no) forecasts, such as the Threat Score, are typically used in the verification of precipitation forecasts. However, these standard methods are affected by the so-called "double-penalty" problem caused by slight displacements in either space or time with respect to the observations. Spatial techniques have recently been developed to help solve this problem. The fractions skill score (FSS), a neighborhood spatial verification method, directly compares the fractional coverage of events in windows surrounding the observations and forecasts. We applied the FSS to hourly precipitation verification by taking hourly forecast products from the GRAPES (Global/Regional Assimilation Prediction System) regional model and quantitative precipitation estimation products from the National Meteorological Information Center of China during July and August 2016, and investigated the difference between these results and those obtained with the traditional category score. We found that the model spin-up period affected the assessment of stability. Systematic errors had an insignificant role in the fraction Brier score and could be ignored. The dispersion of observations followed a diurnal cycle and the standard deviation of the forecast had a similar pattern to the reference maximum of the fraction Brier score. The coefficient of the forecasts and the observations is similar to the FSS; that is, the FSS may be a useful index that can be used to indicate correlation. Compared with the traditional skill score, the FSS has obvious advantages in distinguishing differences in precipitation time series, especially in the assessment of heavy rainfall.

  20. Transdiagnostic Clinical Global Impression Scoring for Routine Clinical Settings. (United States)

    Dunlop, Boadie W; Gray, Jaclyn; Rapaport, Mark H


    Although there is great interest in the improving the ability to track patients' change over time in routine clinical care settings, no standardized transdiagnostic measure is currently available for busy clinicians to apply. The Clinical Global Impression (CGI) scales are simple measures widely used as outcomes in psychiatric clinical trials. However, the CGI suffers from poorly defined scoring anchors. Efforts to improve the anchors by enhancing the anchor descriptions have proven useful but are limited by being disease-specific, thereby acting as a barrier to the routine clinical adoption of the CGI. To inform the development of more broadly applicable CGI scoring anchors, we surveyed 24 clinical trial investigators, asking them to rank-order seven elements that inform their CGI-Severity (CGI-S) scoring. Symptom severity emerged as the most important element in determining CGI-S scores; the functional status of the patient emerged as a second element. Less importance was given to self-report symptom scores, staff observations, or side effects. Relative rankings of the elements' importance did not differ by investigators' experience nor time usually spent with patients. We integrated these results with published illness-specific CGI anchors to develop the Transdiagnostic CGI (T-CGI), which employs standardized scoring anchors applicable across psychiatric illnesses. Pending validity and reliability evaluations, the T-CGI may prove well-suited for inclusion in routine clinical settings and for incorporation into electronic medical records as a simple and useful measure of treatment efficacy.

    Santos, José L; Ho-Urriola, Judith A; González, Andrea; Smalley, Susan V; Domínguez-Vásquez, Patricia; Cataldo, Rodrigo; Obregón, Ana M; Amador, Paola; Weisstaub, Gerardo; Hodgson, M Isabel


    Inadequate eating behavior and physical inactivity contribute to the current epidemic of childhood obesity. The aim of this study was to assess the association between eating behavior scores and childhood obesity in Chilean children. We recruited 126 obese, 44 overweight and 124 normal-weight Chilean children (6-12 years-old; both genders) according to the International Obesity Task Force (IOTF) criteria. Eating behavior scores were calculated using the Child Eating Behavior Questionnaire (CEBQ). Factorial analysis in the culturally-adapted questionnaire for Chilean population was used to confirm the original eight-factor structure of CEBQ. The Cronbach's alpha statistic (>0.7 in most subscales) was used to assess internal consistency. Non-parametric methods were used to assess case-control associations. Eating behavior scores were strongly associated with childhood obesity in Chilean children. Childhood obesity was directly associated with high scores in the subscales "enjoyment of food" (P food responsiveness" (P Food-avoidant subscales "satiety responsiveness" and "slowness in eating" were inversely associated with childhood obesity (P < 0.001). There was a graded relation between the magnitude of these eating behavior scores across groups of normal-weight, overweight and obesity groups. Our study shows a strong and graded association between specific eating behavior scores and childhood obesity in Chile.

  2. Direct concurrent comparison of multiple pediatric acute asthma scoring instruments. (United States)

    Johnson, Michael D; Nkoy, Flory L; Sheng, Xiaoming; Greene, Tom; Stone, Bryan L; Garvin, Jennifer


    Appropriate delivery of Emergency Department (ED) treatment to children with acute asthma requires clinician assessment of acute asthma severity. Various clinical scoring instruments exist to standardize assessment of acute asthma severity in the ED, but their selection remains arbitrary due to few published direct comparisons of their properties. Our objective was to test the feasibility of directly comparing properties of multiple scoring instruments in a pediatric ED. Using a novel approach supported by a composite data collection form, clinicians categorized elements of five scoring instruments before and after initial treatment for 48 patients 2-18 years of age with acute asthma seen at the ED of a tertiary care pediatric hospital ED from August to December 2014. Scoring instruments were compared for inter-rater reliability between clinician types and their ability to predict hospitalization. Inter-rater reliability between clinician types was not different between instruments at any point and was lower (weighted kappa range 0.21-0.55) than values reported elsewhere. Predictive ability of most instruments for hospitalization was higher after treatment than before treatment (p < 0.05) and may vary between instruments after treatment (p = 0.054). We demonstrate the feasibility of comparing multiple clinical scoring instruments simultaneously in ED clinical practice. Scoring instruments had higher predictive ability for hospitalization after treatment than before treatment and may differ in their predictive ability after initial treatment. Definitive conclusions about the best instrument or meaningful comparison between instruments will require a study with a larger sample size.

  3. A Soft Intelligent Risk Evaluation Model for Credit Scoring Classification

    Directory of Open Access Journals (Sweden)

    Mehdi Khashei


    Full Text Available Risk management is one of the most important branches of business and finance. Classification models are the most popular and widely used analytical group of data mining approaches that can greatly help financial decision makers and managers to tackle credit risk problems. However, the literature clearly indicates that, despite proposing numerous classification models, credit scoring is often a difficult task. On the other hand, there is no universal credit-scoring model in the literature that can be accurately and explanatorily used in all circumstances. Therefore, the research for improving the efficiency of credit-scoring models has never stopped. In this paper, a hybrid soft intelligent classification model is proposed for credit-scoring problems. In the proposed model, the unique advantages of the soft computing techniques are used in order to modify the performance of the traditional artificial neural networks in credit scoring. Empirical results of Australian credit card data classifications indicate that the proposed hybrid model outperforms its components, and also other classification models presented for credit scoring. Therefore, the proposed model can be considered as an appropriate alternative tool for binary decision making in business and finance, especially in high uncertainty conditions.

  4. Risk score for contrast induced nephropathy following percutaneous coronary intervention

    International Nuclear Information System (INIS)

    Ghani, Amal Abdel; Tohamy, Khalid Y.


    Contrast-induced nephropathy (CIN) is an important cause of acute renal failure. Identification of risk factors of CIN and creating a simple risk scoring for CIN after percutaneous coronary intervention (PCI) is important. A prospective single center study was conducted in Kuwait chest disease hospital. All patients admitted to chest disease hospital for PCI from March to May 2005 were included in the study. Total of 247 patients were randomly assigned for the development dataset and 100 for the validation set using the simple random method. The overall occurrence of CIN in the development set was 5.52%. Using multivariate analysis; basal Serum creatinine, shock, female gender, multivessel PCI, and diabetes mellitus were identified as risk factors. Scores assigned to different variables yielded basal creatinine > 115 micron mol/L with the highest score(7), followed by shock (3), female gender, multivessel PCI and diabetes mellitus had the same score (2). Patients were further risk stratified into low risk score ( 1 2). The developed CIN model demonstrated good discriminative power in the validation population. In conclusion, use of a simple risk score for CIN can predict the probability of CIN after PCI; this however needs further validation in larger multicenter trials. (author)

  5. Challenges scoring radiation pneumonitis in patients irradiated for lung cancer. (United States)

    Yirmibesoglu, Eda; Higginson, Daniel S; Fayda, Merdan; Rivera, M Patricia; Halle, Jan; Rosenman, Julian; Xie, Liyi; Marks, Lawrence B


    To quantify uncertainties in scoring radiation pneumonitis. Records of 434 patients irradiated for lung cancer from 2000 to 2010 were retrospectively reviewed; IRB-approved study. From these, 121 received ≥ 60 Gy for non-small cell lung cancer (NSCLC) with ≥ 6 months follow-up. Patients where the physicians were uncertain of the diagnosis due to confounding factors were deemed "hard to score". Subgroups were defined based on lung dosimetric parameters, and frequencies in different subgroups were compared via Fisher's exact test. 21/121 of patients were considered to have pneumonitis; median follow 17 months. Of these, 10/21 were "hard to score"; reasons including acute COPD exacerbation, infection, and tumor progression. "Hard to score" pneumonitis was slightly more common in patients with a COPD history (15%) vs. without COPD (4%) (p=0.05); and with a pre-RT FEV1pneumonitis trended to be non-significantly slightly higher in patients higher mean lung doses, V5, and V30. Radiation pneumonitis occurred in 17% of patients undergoing RT for NSCLC; with diagnostic uncertainty in 48% of these. Poor pre-RT pulmonary function increases the rate of "hard to score" pneumonitis. Dosimetric parameters are slightly better related to "unambiguous" than "hard to score" pneumonitis, as expected.

  6. FRAX® Fracture Risks Are Associated with Coronary Artery Calcification Score

    Directory of Open Access Journals (Sweden)

    Tzyy-Ling Chuang


    Full Text Available Purpose. To examine the association between fracture risk assessment tool (FRAX scores and coronary artery calcification (CAC score in adults. Methods. The medical records of 81 adults who underwent both coronary computed tomography and bone mineral density (BMD studies in a package during their health exams were reviewed at a regional hospital in Southern Taiwan. Data collected included health history, anthropomorphic characteristics, clinical laboratory results, and BMD. Fracture risk was determined using FRAX. Univariate and multivariate linear regression analysis were used to assess the association between CAC score and 10-year probability of hip fracture (HF and major osteoporotic fracture (MOF determined by FRAX. Results. The mean age of the patients was 55.8 years, and 63.0% were male. Univariate linear regression analysis showed that increases in MOF and HF risks, as measured by FRAX, were significantly and positively associated with CAC score. Multiple linear regression analysis adjusting for potential confounders showed that CAC score remained significantly associated with four FRAX indicators, including right MOF (r=0.45, P<0.001, left MOF (r=0.31, P=0.021, right HF (r=0.38, P=0.001, and left HF (r=0.23, P=0.049. Conclusions. Increased risks of MOF and HF as determined by FRAX were significantly and independently associated with CAC score.

  7. Schizophrenia polygenic risk score predicts mnemonic hippocampal activity. (United States)

    The use of polygenic risk scores has become a practical translational approach to investigating the complex genetic architecture of schizophrenia, but the link between polygenic risk scores and pathophysiological components of this disorder has been the subject of limited research. We investigated in healthy volunteers whether schizophrenia polygenic risk score predicts hippocampal activity during simple memory encoding, which has been proposed as a risk-associated intermediate phenotype of schizophrenia. We analysed the relationship between polygenic risk scores and hippocampal activity in a discovery sample of 191 unrelated healthy volunteers from the USA and in two independent replication samples of 76 and 137 healthy unrelated participants from Europe and the USA, respectively. Polygenic risk scores for each individual were calculated as the sum of the imputation probability of reference alleles weighted by the natural log of odds ratio from the recent schizophrenia genome-wide association study. We examined hippocampal activity during simple memory encoding of novel visual stimuli assessed using blood oxygen level-dependent functional MRI. Polygenic risk scores were significantly associated with hippocampal activity in the discovery sample [P = 0.016, family-wise error (FWE) corrected within Anatomical Automatic Labeling (AAL) bilateral hippocampal-parahippocampal mask] and in both replication samples (P = 0.033, FWE corrected within AAL right posterior hippocampal-parahippocampal mask in Bari sample, and P = 0.002 uncorrected in the Duke Neurogenetics Study sample). The relationship between polygenic risk scores and hippocampal activity was consistently negative, i.e. lower hippocampal activity in individuals with higher polygenic risk scores, consistent with previous studies reporting decreased hippocampal-parahippocampal activity during declarative memory tasks in patients with schizophrenia and in their healthy siblings. Polygenic risk scores accounted for

  8. Validating the appropriateness of TACOM measure: Comparing TACOM scores with subjective workload scores quantified by NASA-TLX technique

    Energy Technology Data Exchange (ETDEWEB)

    Park, J.; Jung, W. [Integrated Safety Assessment Div., Korea Atomic Energy Research Inst., P.O.Box 105, Duckjin-Dong, Yusong-Ku, Taejon, 305-600 (Korea, Republic of)


    In this study, the appropriateness of the task complexity (TACOM) measure that can quantify the complexity of emergency tasks was investigated by comparing subjective workload scores with the associated TACOM scores. To this end, based on the NASA-TLX (task load index) technique, 18 operators were asked to subjectively estimate perceived workload for 23 emergency tasks that were specified in the emergency operating procedures of the reference nuclear power plants. As the result of comparisons, it was observed that subjective workload scores increase in proportion to the increase of TACOM scores. Therefore, it is expect that the TACOM measure can be used as a serviceable method to quantify the complexity of emergency tasks. (authors)

  15. Comparison of the Classifier Oriented Gait Score and the Gait Profile Score based on imitated gait impairments. (United States)

    Christian, Josef; Kröll, Josef; Schwameder, Hermann


    Common summary measures of gait quality such as the Gait Profile Score (GPS) are based on the principle of measuring a distance from the mean pattern of a healthy reference group in a gait pattern vector space. The recently introduced Classifier Oriented Gait Score (COGS) is a pathology specific score that measures this distance in a unique direction, which is indicated by a linear classifier. This approach has potentially improved the discriminatory power to detect subtle changes in gait patterns but does not incorporate a profile of interpretable sub-scores like the GPS. The main aims of this study were to extend the COGS by decomposing it into interpretable sub-scores as realized in the GPS and to compare the discriminative power of the GPS and COGS. Two types of gait impairments were imitated to enable a high level of control of the gait patterns. Imitated impairments were realized by restricting knee extension and inducing leg length discrepancy. The results showed increased discriminatory power of the COGS for differentiating diverse levels of impairment. Comparison of the GPS and COGS sub-scores and their ability to indicate changes in specific variables supports the validity of both scores. The COGS is an overall measure of gait quality with increased power to detect subtle changes in gait patterns and might be well suited for tracing the effect of a therapeutic treatment over time. The newly introduced sub-scores improved the interpretability of the COGS, which is helpful for practical applications. Copyright © 2017 Elsevier B.V. All rights reserved.

  17. Patient-reported experiences with hospitals: comparison of proxy and patient scores using propensity-score matching. (United States)

    Bjertnaes, Oyvind


    The objective of this study was to compare patient-experience scores between patients with a proxy response and without a proxy response, using propensity-score matching to maximize the comparability between these two groups. Cross-sectional survey. Hospital inpatient services in Norway. Patients were randomly selected from each of the 61 hospitals in Norway during spring 2011. Postal questionnaires were mailed to 23 420 patients after their discharge from hospital. No intervention. All of the patient respondents (n = 8744) and the matched cases (n = 734) were compared with patients with a proxy response (n = 734) on 12 patient-experience indicators using t-tests. Compared with patient respondents, patients with a proxy response had poorer health, were older and were more often discharged from the hospital to another health-care institution (P proxy response yielded significantly lower patient-experience scores than those without a proxy response for 9 of the 12 indicators. Compared with the matched patient group, patients with a proxy response had significantly lower scores for 3 of the 12 indicators and a significantly higher score for one indicator. Differences in scores between patients with a proxy response and the matched patient sample were small, with the largest difference being 4 on a scale of 0-100. Patients with a proxy response report somewhat poorer experiences than those without a proxy response; however, proxies represent a different patient group than the patient group as a whole, and the results were very similar after controlling for these differences.

  18. Prognostic scores for sorafenib-treated hepatocellular carcinoma patients: A new application for the hepatoma arterial embolisation prognostic score. (United States)

    Edeline, J; Blanc, J-F; Campillo-Gimenez, B; Ma, Y-T; King, J; Faluyi, O; Mathurin, J; Ghazi, S; Palmer, D H; Meyer, T


    No prognostic classification is currently used for patients treated with systemic therapies for Hepatocellular Carcinoma (HCC). We retrospectively analysed data from patients treated with sorafenib for HCC from five centres in France and in the United Kingdom (UK). The training set comprised data from two centres and the validation set from three. Variables independently associated with Overall Survival (OS) in the training set were used to build the SAP (Sorafenib Advanced HCC Prognosis) score. The score was tested in the validation set, then compared with other prognostication systems. The training set and validation set included 370 and 468 patients respectively. In the training set, variables independently associated with OS in multivariable analysis were: performance status (PS) >0, alpha-fetoprotein (AFP) >400 ng/ml, tumour size >7 cm, bilirubin >17 μmol/l and albumin Cancer (BCLC) and albumin-bilirubin (ALBI) scores. However, the hepatoma arterial embolisation prognostic (HAP) score showed greater discriminative abilities than the SAP score. In European patients treated with sorafenib, the HAP was the most discriminant prognostic score and may facilitate stratification in trials and inform clinical decision making.

    Full Text Available BACKGROUND Acute appendicitis is one of the most common cause of acute abdominal pain and emergency appendicectomy is the most common emergency surgery. The diagnosis of appendicitis is confirmed by histopathological examination that is not possible before appendicectomy. The negative exploration remains high in the rate of about 15-30%. 1 Scoring systems based on history, clinical examination and basic investigations are there in aiding the diagnosis of acute appendicitis and decreasing negative exploration. This study compares RIPASA and ALVARADO scoring systems in diagnosing acute appendicitis. 2 MATERIALS AND METHODS A comparative study was done between November 2014 to June 2015. Patients diagnosed as acute appendicitis in Department of General Surgery, Government Royapettah Hospital. 100 of them are to be selected on the basis of nonprobability (purposive sampling method. After considering the inclusion and exclusion criteria, 96 were enrolled into the study. A full history, clinical examination and both scoring systems were done on the patients. RESULTS In 96 patients, 46 patients (48% were male and 50 patients (52% were female. 65 patients underwent emergency appendicectomy based on the clinical decision. The sensitivity and specificity of the RIPASA scoring system was 98.0% and 80.43%, respectively. The sensitivity and specificity of the ALVARADO scoring system was 80.43% and 86.95%, respectively. The PPV (positive predictive value of RIPASA and ALVARADO was 84% and 85%, respectively. The NPP (negative predictive value of RIPASA and ALVARADO was 97% and 71%, respectively. The diagnostic accuracy was 89% for RIPASA and 77% for ALVARADO. CONCLUSION The RIPASA scoring is better than ALVARADO scoring in the diagnosis of acute appendicitis.

    Nguyen, Van Thai; Lehes, Lagle; Truong, Thi Thuy Hang; Hoang, Thi Van Anh; Jagomägi, Triin


    The Nasometer is increasingly being used to complement auditory perceptual assessment of nasality. Nasalance scores which are obtained from the Nasometer vary across languages. Normative nasalance scores have been established for many languages but not for the Vietnamese language. The objective of this study was to obtain the normative nasalance scores for Vietnamese-speaking children. In this study, 102 healthy Vietnamese children speaking in the central regional dialect aged from 7 to 9 years (45 boys, 57 girls; mean age = 7.5 years) at a primary school in Hue, Vietnam participated. Three speech stimuli, which were specific for the Vietnamese language, were designed: oral stimuli (19 words and 18 sentences), oro-nasal stimuli (eight sentences) and nasal stimuli (seven sentences). The children were asked to repeat these stimuli after the examiner. The Nasometer II (model 6450) was used to obtain the nasalance scores. The procedure took about 10 minutes for each child. The mean nasalance scores and the standard deviation of each stimulus were: 13.1 ± 5.8 (oral stimuli), 30.7 ± 6.6 (oro-nasal stimuli) and 56.9 ± 9.2 (nasal stimuli). No significant differences between the genders were found. The normative nasalance scores provide essential reference information for clinicians who deal with nasalance disorders, especially patients with cleft palate. The nasalance scores in this study were established for Vietnamese children speaking in the central regional dialect and can be applied to both genders.

  1. Approximating frustration scores in complex networks via perturbed Laplacian spectra (United States)

    Savol, Andrej J.; Chennubhotla, Chakra S.


    Systems of many interacting components, as found in physics, biology, infrastructure, and the social sciences, are often modeled by simple networks of nodes and edges. The real-world systems frequently confront outside intervention or internal damage whose impact must be predicted or minimized, and such perturbations are then mimicked in the models by altering nodes or edges. This leads to the broad issue of how to best quantify changes in a model network after some type of perturbation. In the case of node removal there are many centrality metrics which associate a scalar quantity with the removed node, but it can be difficult to associate the quantities with some intuitive aspect of physical behavior in the network. This presents a serious hurdle to the application of network theory: real-world utility networks are rarely altered according to theoretic principles unless the kinetic impact on the network's users are fully appreciated beforehand. In pursuit of a kinetically interpretable centrality score, we discuss the f-score, or frustration score. Each f-score quantifies whether a selected node accelerates or inhibits global mean first passage times to a second, independently selected target node. We show that this is a natural way of revealing the dynamical importance of a node in some networks. After discussing merits of the f-score metric, we combine spectral and Laplacian matrix theory in order to quickly approximate the exact f-score values, which can otherwise be expensive to compute. Following tests on both synthetic and real medium-sized networks, we report f-score runtime improvements over exact brute force approaches in the range of 0 to 400 % with low error (<3 % ).

  2. Auditory short-term memory activation during score reading. (United States)

    Simoens, Veerle L; Tervaniemi, Mari


    Performing music on the basis of reading a score requires reading ahead of what is being played in order to anticipate the necessary actions to produce the notes. Score reading thus not only involves the decoding of a visual score and the comparison to the auditory feedback, but also short-term storage of the musical information due to the delay of the auditory feedback during reading ahead. This study investigates the mechanisms of encoding of musical information in short-term memory during such a complicated procedure. There were three parts in this study. First, professional musicians participated in an electroencephalographic (EEG) experiment to study the slow wave potentials during a time interval of short-term memory storage in a situation that requires cross-modal translation and short-term storage of visual material to be compared with delayed auditory material, as it is the case in music score reading. This delayed visual-to-auditory matching task was compared with delayed visual-visual and auditory-auditory matching tasks in terms of EEG topography and voltage amplitudes. Second, an additional behavioural experiment was performed to determine which type of distractor would be the most interfering with the score reading-like task. Third, the self-reported strategies of the participants were also analyzed. All three parts of this study point towards the same conclusion according to which during music score reading, the musician most likely first translates the visual score into an auditory cue, probably starting around 700 or 1300 ms, ready for storage and delayed comparison with the auditory feedback.

  3. Association of Fellowship Training With Otolaryngology Training Examination Scores. (United States)

    Akinboyewa, Ibukun; Cabrera-Muffly, Cristina


    No prior studies have evaluated whether residents who pursue fellowship training achieve higher performance on the Otolaryngology Training Examination (OTE) and whether a specific fellowship will demonstrate a correlation with the corresponding specialty-specific OTE score. To determine whether residents pursuing fellowship training achieve higher performance on the OTE and whether fellowship choice is correlated with higher scores on the related subspecialty section of the OTE. This retrospective analysis included 35 residents training in an academic otolaryngology residency program from July 1, 2003, to June 30, 2014. The OTE scores for postgraduate years 2 through 5 and the type of fellowship were collected for all residents meeting inclusion criteria. Data were collected from September 1 to October 15, 2014, and analyzed from October 16 to December 1, 2014. Residents were divided by whether they pursued fellowship training and by the type of fellowship chosen. Outcome measures included comparison of scores between residents who pursued vs those who did not pursue fellowship training and comparison of subspecialty OTE scores between residents who pursued the corresponding fellowship and those who did not. Of the 35 residents who met the inclusion criteria (24 men and 11 women), 17 (49%) pursued fellowship training. The 3 most common fellowship choices were facial plastic and reconstructive surgery, pediatric otolaryngology, and rhinology (4 residents each [24%]). For all residents, mean scores on the OTE improved each subsequent training year, but this difference was only significant between postgraduate years 2 and 3 (from 60.9% to 68.6% correct; P otolaryngology, 72.9% vs 71.3% [P = .79]; and for rhinology, 72.2% vs 71.2% [P = .91]). Residents who pursued fellowship training did not achieve higher scores on the OTE in any examination year compared with residents who did not pursue fellowship training and did not achieve higher scores within the OTE

  4. Validity and reliability of Nintendo Wii Fit balance scores. (United States)

    Wikstrom, Erik A


    Interactive gaming systems have the potential to help rehabilitate patients with musculoskeletal conditions. The Nintendo Wii Balance Board, which is part of the Wii Fit game, could be an effective tool to monitor progress during rehabilitation because the board and game can provide objective measures of balance. However, the validity and reliability of Wii Fit balance scores remain unknown. To determine the concurrent validity of balance scores produced by the Wii Fit game and the intrasession and intersession reliability of Wii Fit balance scores. Descriptive laboratory study. Sports medicine research laboratory. Forty-five recreationally active participants (age = 27.0 ± 9.8 years, height = 170.9 ± 9.2 cm, mass = 72.4 ± 11.8 kg) with a heterogeneous history of lower extremity injury. Participants completed a single-limb-stance task on a force plate and the Star Excursion Balance Test (SEBT) during the first test session. Twelve Wii Fit balance activities were completed during 2 test sessions separated by 1 week. Postural sway in the anteroposterior (AP) and mediolateral (ML) directions and the AP, ML, and resultant center-of-pressure (COP) excursions were calculated from the single-limb stance. The normalized reach distance was recorded for the anterior, posteromedial, and posterolateral directions of the SEBT. Wii Fit balance scores that the game software generated also were recorded. All 96 of the calculated correlation coefficients among Wii Fit activity outcomes and established balance outcomes were interpreted as poor (r Wii Fit balance activity scores ranged from good (intraclass correlation coefficient [ICC] = 0.80) to poor (ICC = 0.39), with 8 activities having poor intrasession reliability. Similarly, 11 of the 12 Wii Fit balance activity scores demonstrated poor intersession reliability, with scores ranging from fair (ICC = 0.74) to poor (ICC = 0.29). Wii Fit balance activity scores had poor concurrent validity relative to COP outcomes and SEBT

    To determine medical, ophthalmologic, and demographic predictors of cognitive function scores as measured by the Telephone Interview for Cognitive Status (TICS), an adaptation of the Folstein Mini-Mental Status Exam. A secondary objective was to perform an item-by-item analysis of the TICS scores to determine which items correlated most highly with the overall scores. Cross-sectional cohort study. The Glaucoma Consultation Service of the Massachusetts Eye and Ear Infirmary. 472 of 565 consecutive patients age 65 and older who were seen at the Glaucoma Consultation Service between November 1, 1987 and October 31, 1988. Each subject had a standard visual examination and review of medical history at entry, followed by a telephone interview that collected information on demographic characteristics, cognitive status, health status, accidents, falls, symptoms of depression, and alcohol intake. A multivariate linear regression model of correlates of TICS score found the strongest correlates to be education, age, occupation, and the presence of depressive symptoms. The only significant ocular condition that correlated with lower TICS score was the presence of surgical aphakia (model R2 = .46). Forty-six percent (216/472) of patients fell below the established definition of normal on the mental status scale. In a logistic regression analysis, the strongest correlates of an abnormal cognitive function score were age, diabetes, educational status, and occupational status. An item analysis using step-wise linear regression showed that 85 percent of the variance in the TICS score was explained by the ability to perform serial sevens and to repeat 10 items immediately after hearing them. Educational status correlated most highly with both of these items (Kendall Tau R = .43 and Kendall Tau R = .30, respectively). Education, occupation, depression, and age were the strongest correlates of the score on this new screening test for assessing cognitive status. These factors were

    Pemphigus is a rare autoimmune blistering disease with different phenotypes. The evaluation of therapeutic interventions requires a reliable, valid and feasible to use measurement. However, there is no gold standard to measure the disease activity in clinical trials. In this study we aimed to introduce the pemphigus vulgaris activity score (PVAS) measurement and to assess the convergent validity with the experts' opinion of disease activity. In PVAS scoring, the distribution of pemphigus vulgaris antigen expression in different anatomical regions is taking in to account with special consideration of the healing process. PVAS is a 0-18 scale, based on the extent of mucocutaneous involvement, type of lesion and the presence of Nikolsky's sign. The sum of the scores of total number of lesions, number of different anatomic regions involvement and Nikolsky's sign is weighted by the type of lesion. In the present study, PVAS was assessed in 50 patients diagnosed with pemphigus vulgaris by one dermatologist. Independently, five blinded experts scored all the patients through physician's global assessment (PGA). The convergent validity with experts' opinion was assessed. The Spearman coefficient of correlation showed the acceptable value of 0.751 (95%CI: 0.534- 0.876). PVAS is a valid, objective and simple-to-use scoring measurement. It showed a good correlation with PGA of pemphigus disease activity in Iranian patients with pemphigus vulgaris.

  9. Technology Credit Scoring Based on a Quantification Method

    Directory of Open Access Journals (Sweden)

    Yonghan Ju


    Full Text Available Credit scoring models are usually formulated by fitting the probability of loan default as a function of individual evaluation attributes. Typically, these attributes are measured using a Likert-type scale, but are treated as interval scale explanatory variables to predict loan defaults. Existing models also do not distinguish between types of default, although they vary: default by an insolvent company and default by an insolvent debtor. This practice can bias the results. In this paper, we applied Quantification Method II, a categorical version of canonical correlation analysis, to determine the relationship between two sets of categorical variables: a set of default types and a set of evaluation attributes. We distinguished between two types of loan default patterns based on quantification scores. In the first set of quantification scores, we found knowledge management, new technology development, and venture registration as important predictors of default from non-default status. Based on the second quantification score, we found that the technology and profitability factors influence loan defaults due to an insolvent company. Finally, we proposed a credit-risk rating model based on the quantification score.

  10. Digital watermarking for the protection of music scores (United States)

    Schmucker, Martin; Busch, Christoph; Pant, Anoop


    The need for protection mechanisms for multimedia content is widely recognized. In the past digital watermarking algorithms for images have been developed that provide a certain level of protection for colored or gray-scale images. Since classical raster-oriented watermarking algorithms do not satisfy the needs for symbol oriented music score images we present in this paper a solution that should give promising robustness of the watermark at minimal visibility impact. This solution respects the content of binary images and can be considered as a symbolic interpretation and modification of music scores. Some music symbols are used by changing their features for hiding an information string in a music score. The advantage is its robustness and invisibility. Regarding the invisibility a musician should under no circumstances be impeded in reading the music. One must even consider the fact of being influenced unconsciously. For example, it might be more difficult to concentrate on a music sheet if the symbols were changed invisibly. The most probable way of distributing music scores is the analog (paper) form. Music scores are copied and distributed. So watermarks should be readable even after multiple copy procedures. By choosing suitable features a blind detection of the watermark is possible.

    Full Text Available Abstract Background Inadequate eating behavior and physical inactivity contribute to the current epidemic of childhood obesity. The aim of this study was to assess the association between eating behavior scores and childhood obesity in Chilean children. Design and methods We recruited 126 obese, 44 overweight and 124 normal-weight Chilean children (6-12 years-old; both genders according to the International Obesity Task Force (IOTF criteria. Eating behavior scores were calculated using the Child Eating Behavior Questionnaire (CEBQ. Factorial analysis in the culturally-adapted questionnaire for Chilean population was used to confirm the original eight-factor structure of CEBQ. The Cronbach's alpha statistic (>0.7 in most subscales was used to assess internal consistency. Non-parametric methods were used to assess case-control associations. Results Eating behavior scores were strongly associated with childhood obesity in Chilean children. Childhood obesity was directly associated with high scores in the subscales "enjoyment of food" (P Conclusion Our study shows a strong and graded association between specific eating behavior scores and childhood obesity in Chile.

  12. Evaluation of revised trauma score in poly- traumatized patients

    Ahmad, H.N.


    Objective: To determine the prognostic value and reliability of revised trauma score (RTS) in polytraumatized patients. Subjects and Methods: Thirty adult patients of road traffic accidents sustaining multisystem injuries due to high energy blunt trauma were managed according to the protocols of advanced trauma life support (ATLS) and from their first set of data RTS was calculated. Score of each patient was compared with his final outcome at the time of discharge from the hospital. Results: The revised trauma score was found to be a reliable predictor of prognosis of polytraumatized patients but a potentially weak predictor for those patients having severe injury involving a single anatomical region. The higher the RTS the better the prognosis of polytrauma patient and vice versa. Revised trauma score <8 turned out to be an indicator of severe injury with high mortality and morbidity and overall mortality in polytraumatized patients was 26.66%. However, RTS-6 was associated with 50% mortality. Conclusion: The revised trauma score is a reliable indicator of prognosis of polytraumatized patients. Therefore, it can be used for field and emergency room triage. (author)

  13. Dissection videos do not improve anatomy examination scores. (United States)

    Mahmud, Waqas; Hyder, Omar; Butt, Jamaal; Aftab, Arsalan


    In this quasi-experimental study, we describe the effect of showing dissection videos on first-year medical students' performance in terms of test scores during a gross anatomy course. We also surveyed students' perception regarding the showing of dissection videos. Two hundred eighty-seven first-year medical students at Rawalpindi Medical College in Pakistan, divided into two groups, dissected one limb in first term and switched over to the other limb in the second term. During the second term, instruction was supplemented by dissection videos. Second-term anatomy examination marks were compared with first-term scores and with results from first-year medical students in previous years. Multiple linear regression analysis was performed, with term scores (continuous, 0-200) as the dependent variable. Students shown dissection videos scored 1.26 marks higher than those not shown. The relationship was not statistically significant (95% CI: -1.11, 3.70; P = 0.314). Ninety-three percent of students favored regular inclusion of dissection videos in curriculum, and 50% termed it the best source for learning gross anatomy. Seventy-six percent of students did not perform regular cadaver dissection. The most frequent reason cited for not performing regular dissection was high student-cadaver ratio. Dissection videos did not improve performance on final examination scores; however, students favored their use. Copyright © 2011 American Association of Anatomists.

    Livsey, Jacqueline E.; Routledge, Jacqueline; Burns, Meriel; Swindell, Rick; Davidson, Susan E.; Cowan, Richard A.; Logue, John P.; Wylie, James P.


    Background and purpose: To assess the correlation between different general and organ specific quality of life and morbidity scoring methods in a cohort of men treated with radical radiotherapy for prostate cancer. Materials and methods: Men who had been treated with radical radiotherapy (50 Gy in 16 fractions over 21 days) for localized prostate cancer more than 3 years previously and who had no evidence of recurrent disease were invited to take part in the study. A total of 101 of 135 invited patients agreed and completed LENT/SOMA, UCLA Prostate Cancer Index, and 36 item RAND Health survey questionnaires. Results: The patients had comparable results with other published series with respect to the UCLA and SF-36 indices. There was significant correlation between the corresponding parts of the UCLA and LENT/SOMA scales (P<0.0005). However, for the same symptoms, a patient tended to score lower (worse) on the UCLA scale in comparison to LENT/SOMA. The relationship between the average LENT/SOMA score and maximum score was also not straightforward with each set of data revealing different information. Conclusions: The LENT/SOMA questions were, in the main, more wide-ranging and informative than the UCLA index. It is helpful to give both the overall and maximum LENT/SOMA scores to most efficiently use all of the data. There may need to be a further LENT/SOMA question to allow both symptoms of tenesmus and faecal urgency to be fully addressed

    Full Text Available Objective: The World health organization (WHO has accepted Keith Edward scoring system for the diagnosis of childhood tuberculosis (TB. In the present study, we evaluated this scoring system. Methods and Results: We included 53 children with confirmed TB involving different organs, admitted in NB Medical College, during two years period as cases; and 50 randomly selected, age, sex, and organ matched confirmed non-TB cases as controls. We noticed 15.1% false negative and 22% false positive results in our study, and the scoring system had 84.9% sensitivity, 78% specificity, and 80.36% positive predictive value. Likelihood ratio positive (LR+ was 3.86, likelihood ratio negative (LR- was 0.19, and overall agreement was 81.55%. We observed that Keith Edward scoring system was less effective in children suffering from non-TB chronic diseases (false positive rate: 45.5%. We found no significant difference in nutritional status between study and control groups (P = 0.65. We noticed that more than 15-mm indurations for tuberculin test were specific for TB in children. Conclusion: We concluded that Keith Edward scoring system is good for public health purpose, but there is a scope for improvement, and further study is required for this purpose.

    Convers, M; Langeron, A; Sass, C; Moulin, J-J; Augier, A; Varlet, M-N; Seffert, P; Chêne, G


    To describe a validated and multifactorial deprivation score to study the relationship between socioeconomic deprivation and perinatal risks. The index of deprivation EPICES (Evaluation of Precarity and Inequalities in Health Examination Centers) was used to characterize the deprivation status of 234 women in post-partum in comparison with perinatal morbidity. The cutoff value of 30.7 was the threshold to define deprivation. Two hundred and eight patients were included in this retrospective study from whom 48 (23%) had a score of deprivation higher than 30.7. Maternofetal morbidity was more severe in deprived patients. The current results show that the EPICES score could be a useful obstetrical tool for the identification of deprived women during pregnancy. Copyright © 2011 Elsevier Masson SAS.

  17. Background Variables, Levels of Aggregation, and Standardized Test Scores

    Directory of Open Access Journals (Sweden)

    Sharon E. Paulson


    Full Text Available This article examines the role of student demographic characteristics in standardized achievement test scores at both the individual level and aggregated at the state, district, school levels. For several data sets, the majority of the variance among states, districts, and schools was related to demographic characteristics. Where these background variables outside of the control of schools significantly affected averaged scores, and test scores result in high stakes consequences, benefits and sanctions may be inappropriately applied. Furthermore, disaggregating the data by race, SES, limited English, or other groupings ignores the significant confounding and cumulative effects of belonging to more than one disadvantaged group. With these approaches to evaluation being fundamental to the No Child Left Behind mandates, the danger of misinterpretation and inappropriate application of sanctions is substantial.

  18. Perceived Competence, Discrepancy Scores, and Global Self-Worth. (United States)

    Rose, Elizabeth; Larkin, Dawne


    According to Harter (1985a), global self-worth (GSW) can be predicted from the relationship between perceptions of competence and importance ratings. In this study, we employed Harter's (1985b) Importance Rating Scale (IRS) and Self-Perception Profile for Children (SPPC) to examine importance ratings, discrepancy scores, and domain-specific perceptions of competence as predictors of GSW. Children (N = 130, 62 boys and 68 girls) aged 8-12 years were categorized into high (HMC; n = 62) and low motor coordination (LMC; n = 68) groups according to their scores on a motor proficiency battery (McCarron, 1982). Regression analyses using domain-specific perceptions of competence, importance, and discrepancy scores confirmed that self-perception ratings were the best predictors of GSW. For both groups, perceptions of physical appearance, social acceptance, and behavioral conduct contributed significantly to prediction of GSW. By contrast, perceived athletic competence increased prediction of GSW for the HMC group but not the LMC group.

  19. A Study on Text-Score Disagreement in Online Reviews

    DEFF Research Database (Denmark)

    Fazzolari, Michela; Cozza, Vittoria; Petrocchi, Marinella


    In this paper, we focus on online reviews and employ artificial intelligence tools, taken from the cognitive computing field, to help understand the relationships between the textual part of the review and the assigned numerical score. We move from the intuitions that (1) a set of textual reviews...... expressing different sentiments may feature the same score (and vice-versa), and (2) detecting and analyzing the mismatches between the review content and the actual score may benefit both service providers and consumers, by highlighting specific factors of satisfaction (and dissatisfaction) in texts....... To prove the intuitions, we adopt sentiment analysis techniques and we concentrate on hotel reviews, to find polarity mismatches therein. In particular, we first train a text classifier with a set of annotated hotel reviews, taken from the Booking website. Then, we analyze a large dataset, with around 160k...

  20. Splitting the BLOSUM Score into Numbers of Biological Significance

    Directory of Open Access Journals (Sweden)

    Tossi Alessandro


    Full Text Available Mathematical tools developed in the context of Shannon information theory were used to analyze the meaning of the BLOSUM score, which was split into three components termed as the BLOSUM spectrum (or BLOSpectrum. These relate respectively to the sequence convergence (the stochastic similarity of the two protein sequences, to the background frequency divergence (typicality of the amino acid probability distribution in each sequence, and to the target frequency divergence (compliance of the amino acid variations between the two sequences to the protein model implicit in the BLOCKS database. This treatment sharpens the protein sequence comparison, providing a rationale for the biological significance of the obtained score, and helps to identify weakly related sequences. Moreover, the BLOSpectrum can guide the choice of the most appropriate scoring matrix, tailoring it to the evolutionary divergence associated with the two sequences, or indicate if a compositionally adjusted matrix could perform better.

  1. Comparison of five actigraphy scoring methods with bipolar disorder. (United States)

    Boudebesse, Carole; Leboyer, Marion; Begley, Amy; Wood, Annette; Miewald, Jean; Hall, Martica; Frank, Ellen; Kupfer, David; Germain, Anne


    The goal of this study was to compare 5 actigraphy scoring methods in a sample of 18 remitted patients with bipolar disorder. Actigraphy records were processed using five different scoring methods relying on the sleep diary; the event-marker; the software-provided automatic algorithm; the automatic algorithm supplemented by the event-marker; visual inspection (VI) only. The algorithm and the VI methods differed from the other methods for many actigraphy parameters of interest. Particularly, the algorithm method yielded longer sleep duration, and the VI method yielded shorter sleep latency compared to the other methods. The present findings provide guidance for the selection of signal processing method based on sleep parameters of interest, time-cue sources and availability, and related scoring time costs for the study.

  2. Lecture Evaluations by Medical Students: Concepts That Correlate With Scores. (United States)

    Jen, Aaron; Webb, Emily M; Ahearn, Bren; Naeger, David M


    The didactic lecture remains one of the most popular teaching formats in medical education; yet, factors that most influence lecturing success in radiology education are unknown. The purpose of this study is to identify patterns of narrative student feedback that are associated with relatively higher and lower evaluation scores. All student evaluations from our core radiology elective during 1 year were compiled. All evaluation comments were tagged, to identify discrete descriptive concepts. Correlation coefficients were calculated, for each tag with mean evaluation scores. Tags that were the most strongly associated with the highest- versus lowest-rated (> or < 1 SD) lectures were identified. A total of 3,262 comments, on 273 lectures, rated by 77 senior medical students, were analyzed. The mean lecture score was 8.96 ± 0.62. Three tags were significantly positively correlated with lecture score: "interactive"; "fun/engaging"; and "practical/important content" (r = 0.39, r = 0.34, and r = 0.32, respectively; all P < .001). More tags (n = 12) were significantly negatively correlated with score; the three tags with the strongest such correlation were: "not interactive"; "poorly structured or unevenly paced"; and "content too detailed or abundant" (r = -0.44, r = -0.39, and r = -0.36, respectively; all P < .001). Analysis of only the highest- and lowest-rated lectures yielded similar results. Several factors were identified that were strongly associated with lecture score. Among the actionable characteristics, interactive lectures with appropriately targeted content (ie, practical/useful) were the most highly rated. Copyright © 2016 American College of Radiology.

  3. Spinal appearance questionnaire: factor analysis, scoring, reliability, and validity testing. (United States)

    Carreon, Leah Y; Sanders, James O; Polly, David W; Sucato, Daniel J; Parent, Stefan; Roy-Beaudry, Marjolaine; Hopkins, Jeffrey; McClung, Anna; Bratcher, Kelly R; Diamond, Beverly E


    Cross sectional. This study presents the factor analysis of the Spinal Appearance Questionnaire (SAQ) and its psychometric properties. Although the SAQ has been administered to a large sample of patients with adolescent idiopathic scoliosis (AIS) treated surgically, its psychometric properties have not been fully evaluated. This study presents the factor analysis and scoring of the SAQ and evaluates its psychometric properties. The SAQ and the Scoliosis Research Society-22 (SRS-22) were administered to AIS patients who were being observed, braced or scheduled for surgery. Standard demographic data and radiographic measures including Lenke type and curve magnitude were also collected. Of the 1802 patients, 83% were female; with a mean age of 14.8 years and mean initial Cobb angle of 55.8° (range, 0°-123°). From the 32 items of the SAQ, 15 loaded on two factors with consistent and significant correlations across all Lenke types. There is an Appearance (items 1-10) and an Expectations factor (items 12-15). Responses are summed giving a range of 5 to 50 for the Appearance domain and 5 to 20 for the Expectations domain. The Cronbach's α was 0.88 for both domains and Total score with a test-retest reliability of 0.81 for Appearance and 0.91 for Expectations. Correlations with major curve magnitude were higher for the SAQ Appearance and SAQ Total scores compared to correlations between the SRS Appearance and SRS Total scores. The SAQ and SRS-22 Scores were statistically significantly different in patients who were scheduled for surgery compared to those who were observed or braced. The SAQ is a valid measure of self-image in patients with AIS with greater correlation to curve magnitude than SRS Appearance and Total score. It also discriminates between patients who require surgery from those who do not.

    Zook, Heather G; Kharbanda, Anupam B; Flood, Andrew; Harmon, Brian; Puumala, Susan E; Payne, Nathaniel R


    Racial disparities are frequently reported in emergency department (ED) care. To examine racial differences in triage scores of pediatric ED patients. We hypothesized that racial differences existed but could be explained after adjusting for sociodemographic and clinical factors. We examined all visits to two urban, pediatric EDs between August 2009 and March 2010. Demographic and clinical data were electronically extracted from the medical record. We used logistic regression to analyze racial differences in triage scores, controlling for possible covariates. There were 54,505 ED visits during the study period, with 7216 (13.2%) resulting in hospital admission. White patients accounted for 36.4% of visits, African Americans 28.5%, Hispanics 18.0%, Asians 4.1%, and American Indians 1.8%. After adjusting for potential confounders, African American (adjusted odds ratio [aOR] 1.89, 95% confidence interval [CI] 1.69-2.12), Hispanic (aOR 1.77, 95% CI 1.55-2.02), and American Indian (aOR 2.57, 95% CI 1.80-3.66) patients received lower-acuity triage scores than Whites. In three out of four subgroup analyses based on presenting complaints (breathing difficulty, abdominal pain, fever), African Americans and Hispanics had higher odds of receiving low-acuity triage scores. No racial differences were detected for patients with presenting complaints of laceration/head injury/arm injury. However, among patients admitted to the hospital, African Americans (aOR 1.47, 95% CI 1.13-1.90) and Hispanics (aOR 1.71, CI 1.22-2.39) received lower-acuity triage scores than Whites. After adjusting for available sociodemographic and clinical covariates, African American, Hispanic, and American Indian patients received lower-acuity triage scores than Whites.

    The prediction of genetic predispositions to ischemic stroke (IS) may allow the identification of individuals at elevated risk and thereby prevent IS in clinical practice. Previously developed weighted multilocus genetic risk scores showed limited predictive ability for IS. Here, we investigated the predictive ability of a newer method, polygenic risk score (polyGRS), based on the idea that a few strong signals, as well as several weaker signals, can be collectively informative to determine IS risk. We genotyped 13 214 Japanese individuals with IS and 26 470 controls (derivation samples) and generated both multilocus genetic risk scores and polyGRS, using the same derivation data set. The predictive abilities of each scoring system were then assessed using 2 independent sets of Japanese samples (KyushuU and JPJM data sets). In both validation data sets, polyGRS was shown to be significantly associated with IS, but weighted multilocus genetic risk scores was not. Comparing the highest with the lowest polyGRS quintile, the odds ratios for IS were 1.75 (95% confidence interval, 1.33-2.31) and 1.99 (95% confidence interval, 1.19-3.33) in the KyushuU and JPJM samples, respectively. Using the KyushuU samples, the addition of polyGRS to a nongenetic risk model resulted in a significant improvement of the predictive ability (net reclassification improvement=0.151; P<0.001). The polyGRS was shown to be superior to weighted multilocus genetic risk scores as an IS prediction model. Thus, together with the nongenetic risk factors, polyGRS will provide valuable information for individual risk assessment and management of modifiable risk factors. © 2016 The Authors.

    Polovina Snežana


    Full Text Available Background/Aim. The Fracture Risk Assessment Tool (FRAX® score is the 10-year estimated risk calculation tool for bone fracture that includes clinical data and hip bone mineral density measured by dual-energy x-ray absorptiometry (DXA. The aim of this cross-sectional study was to elucidate the ability of the FRAX® score in discriminating between bone fracture positive and negative pre- and post-menopausal women with subclinical hyperthyroidism. Methods. The bone mineral density (by DXA, thyroid stimulating hormone (TSH level, free thyroxine (fT4 level, thyroid peroxidase antibodies (TPOAb titre, osteocalcin and beta-cross-laps were measured in 27 pre- and post-menopausal women with newly discovered subclinical hyperthyroidism [age 58.85 ± 7.83 years, body mass index (BMI 27.89 ± 3.46 kg/m2, menopause onset in 46.88 ± 10.21 years] and 51 matched euthyroid controls (age 59.69 ± 5.72 years, BMI 27.68 ± 4.66 kg/m2, menopause onset in 48.53 ± 4.58 years. The etiology of subclinical hyperthyroisims was autoimmune thyroid disease or toxic goiter. FRAX® score calculation was performed in both groups. Results. In the group with subclinical hyperthyroidism the main FRAX® score was significantly higher than in the controls (6.50 ± 1.58 vs 4.35 ± 1.56 respectively; p = 0.015. The FRAX® score for hip was also higher in the evaluated group than in the controls (1.33 ± 3.92 vs 0.50 ± 0.46 respectively; p = 0.022. There was no correlations between low TSH and fracture risk (p > 0.05. The ability of the FRAX® score in discriminating between bone fracture positive and negative pre- and postmenopausal female subjects (p < 0.001 is presented by the area under the curve (AUC plotted via ROC analysis. The determined FRAX score cut-off value by this analysis was 6%, with estimated sensitivity and specificity of 95% and 75.9%, respectively. Conclusion. Pre- and postmenopausal women with subclinical hyperthyroidism have higher FRAX® scores and thus

  9. Martial arts intervention decreases pain scores in children with malignancy. (United States)

    Bluth, Martin H; Thomas, Ronald; Cohen, Cindy; Bluth, Amanda C; Goldberg, Elimelech


    Martial arts intervention in disease has been mostly limited to adult inflammatory, musculoskeletal, or motor diseases, where a mechanical intervention effects positive change. However, the application and benefit to pain management in childhood malignancy are not well described. Here, we assess the effects of defined martial arts intervention in children with cancer with respect to their pain perception and management. Sixty-four children with childhood malignancies were enrolled in a martial arts program, which encompassed both meditation and movement modalities. Pain scores (0-10) were recorded pre- and post- 1-hour session intervention. Pain scores were crossed by total visits and tabulated by whether participant pain reduced at least 1 unit, stayed the same, or increased in intensity immediately after (post) participation session. Differences in pain scores were further compared by age and sex. Prepain and postpain scale data were measured for 64 participants, 43 males (67.2%) and 21 females (32.8%), ranging from 3 years to 19 years. Preintervention and postintervention data were obtained for 223 individual session visits. Mean number of patient participation visits was 1.8±1.6 (range one to nine visits). Of 116 individual measured sessions where the participants began with a pain score of at least 1, pain intensity reduced ≥1 unit in 85.3% (99/116) of visits, remained the same in 7.8% (9/116), and increased in 6.9% (8/116). For the majority (96.3%; 77/80) of sessions, participants began with a prepain intensity score of at least 5-10 with reduction in pain intensity following the session. The overall mean pain score presession visit was reduced bŷ40% (pre: 5.95±2.64 and post: 3.03±2.45 [95% CI: 2.34-3.50]; P ≤0.001). Median pain intensity scores had greater reductions with increased age of participants (3-6 years [-1], 7-10 years [-2], 11-14 years [-3], and 15-19 years [-4]). Martial arts intervention can provide a useful modality to decrease pain in

  10. Development of the knowledge-based and empirical combined scoring algorithm (KECSA) to score protein-ligand interactions. (United States)

    Zheng, Zheng; Merz, Kenneth M


    We describe a novel knowledge-based protein-ligand scoring function that employs a new definition for the reference state, allowing us to relate a statistical potential to a Lennard-Jones (LJ) potential. In this way, the LJ potential parameters were generated from protein-ligand complex structural data contained in the Protein Databank (PDB). Forty-nine (49) types of atomic pairwise interactions were derived using this method, which we call the knowledge-based and empirical combined scoring algorithm (KECSA). Two validation benchmarks were introduced to test the performance of KECSA. The first validation benchmark included two test sets that address the training set and enthalpy/entropy of KECSA. The second validation benchmark suite included two large-scale and five small-scale test sets, to compare the reproducibility of KECSA, with respect to two empirical score functions previously developed in our laboratory (LISA and LISA+), as well as to other well-known scoring methods. Validation results illustrate that KECSA shows improved performance in all test sets when compared with other scoring methods, especially in its ability to minimize the root mean square error (RMSE). LISA and LISA+ displayed similar performance using the correlation coefficient and Kendall τ as the metric of quality for some of the small test sets. Further pathways for improvement are discussed for which would allow KECSA to be more sensitive to subtle changes in ligand structure.

    Jensen, Peter S; Sorensen, Helge B D; Jennum, Poul


    The aim of this study was to develop a fully automatic sleep scoring algorithm on the basis of a reproduction of new international sleep scoring criteria from the American Academy of Sleep Medicine. A biomedical signal processing algorithm was developed, allowing for automatic sleep depth...... with Parkinson disease or multiple system atrophy. This led to quantification of automatic versus manual epoch-by-epoch agreement rates for both normals and abnormals. Resulting average agreement rates were 87.7% (Cohen's Kappa: 0.79) and 68.2% (Cohen's Kappa: 0.26) in the normal and abnormal group, respectively....... Based on an observed reliability of the manual scorer of 92.5% (Cohen's Kappa: 0.87) in the normal group and 85.3% (Cohen's Kappa: 0.73) in the abnormal group, this study concluded that although the developed algorithm was capable of scoring normal sleep with an accuracy around the manual interscorer...

The ROC MIC values were associated with high degrees of misclassification. Values obtained by the mean change method were considered less reliable because these estimates are derived from subgroups...

  14. Performance of a novel clinical score, the Pediatric Asthma Severity Score (PASS), in the evaluation of acute asthma. (United States)

    Gorelick, Marc H; Stevens, Molly W; Schultz, Theresa R; Scribano, Philip V


    To evaluate the reliability, validity, and responsiveness of a new clinical asthma score, the Pediatric Asthma Severity Score (PASS), in children aged 1 through 18 years in an acute clinical setting. This was a prospective cohort study of children treated for acute asthma at two urban pediatric emergency departments (EDs). A total of 852 patients were enrolled at one site and 369 at the second site. Clinical findings were assessed at the start of the ED visit, after one hour of treatment, and at the time of disposition. Peak expiratory flow rate (PEFR) (for patients aged 6 years and older) and pulse oximetry were also measured. Composite scores including three, four, or five clinical findings were evaluated, and the three-item score (wheezing, prolonged expiration, and work of breathing) was selected as the PASS. Interobserver reliability for the PASS was good to excellent (kappa = 0.72 to 0.83). There was a significant correlation between PASS and PEFR (r = 0.27 to 0.37) and pulse oximetry (r = 0.29 to 0.41) at various time points. The PASS was able to discriminate between those patients who did and did not require hospitalization, with area under the receiver operating characteristic curve of 0.82. Finally, the PASS was shown to be responsive, with a 48% relative increase in score from start to end of treatment and an overall effect size of 0.62, indicating a moderate to large effect. This clinical score, the PASS, based on three clinical findings, is a reliable and valid measure of asthma severity in children and shows both discriminative and responsive properties. The PASS may be a useful tool to assess acute asthma severity for clinical and research purposes.

  15. Antithrombotic drugs and non-variceal bleeding outcomes and risk scoring systems: comparison of Glasgow Blatchford, Rockall and Charlson scores (United States)

    Taha, Ali S; McCloskey, Caroline; Craigen, Theresa; Angerson, Wilson J


    Objectives Antithrombotic drugs (ATDs) cause non-variceal upper gastrointestinal bleeding (NVUGIB). Risk scoring systems have not been validated in ATD users. We compared Blatchford, Rockall and Charlson scores in predicting outcomes of NVUGIB in ATD users and controls. Methods A total of 2071 patients with NVUGIB were grouped into ATD users (n=851) and controls (n=1220) in a single-centre retrospective analysis. Outcomes included duration of hospital admission, the need for blood transfusion, rebleeding requiring surgery and 30-day mortality. Results Duration of admission correlated with all scores in controls, but correlations were significantly weaker in ATD users. Rank correlation coefficients in control versus ATD: 0.45 vs 0.20 for Blatchford; 0.48 vs 0.32 for Rockall and 0.42 vs 0.26 for Charlson (all p<0.001). The need for transfusion was best predicted by Blatchford (p<0.001 vs Rockall and Charlson in both ATD users and controls), but all scores performed less well in ATD users. Area under the receiver operation characteristic curve (AUC) in control versus ATD: 0.90 vs 0.85 for Blatchford; 0.77 vs 0.61 for Rockall and 0.69 vs 0.56 for Charlson (all p<0.005). In predicting surgery, Rockall performed best; while mortality was best predicted by Charlson with lower AUCs in ATD patients than controls (p<0.05). Stratification showed the scores' performance to be age-dependent. Conclusions Blatchford score was the strongest predictor of transfusion, Rockall's had the strongest correlation with duration of admission and with rebleeding requiring surgery and Charlson was best in predicting 30-day mortality. Modifications of these systems should be explored to improve their efficiency in ATD users. PMID:28839866

  16. The variability in Oxford hip and knee scores in the preoperative period: is there an ideal time to score? (United States)

    Quah, C; Holmes, D; Khan, T; Cockshott, S; Lewis, J; Stephen, A


    Background All NHS-funded providers are required to collect and report patient-reported outcome measures for hip and knee arthroplasty. Although there are established guidelines for timing such measures following arthroplasty, there are no specific time-points for collection in the preoperative period. The primary aim of this study was to identify whether there was a significant amount of variability in the Oxford hip and knee scores prior to surgical intervention when completed in the outpatient clinic at the time of listing for arthroplasty or when completed at the preoperative assessment clinic. Methods A prospective cohort study of patients listed for primary hip or knee arthroplasty was conducted. Patients were asked to fill in a preoperative Oxford score in the outpatient clinic at the time of listing. They were then invited to fill in the official outcome measures questionnaire at the preoperative assessment clinic. The postoperative Oxford score was then completed when the patient was seen again at their postoperative follow up in clinic. Results Of the total of 109 patients included in this study period, there were 18 (17%) who had a worse score of 4 or more points difference and 43 (39.4%) who had an improvement of 4 or more points difference when the scores were compared between time of listing at the outpatient and at the preoperative assessment clinic. There was a statistically significant difference (P = 0.0054) in the mean Oxford scores. Conclusions The results of our study suggest that there should be standardisation of timing for completing the preoperative patient-reported outcome measures.

  17. Testing the Validity of Taxonic Schizotypy Using Genetic and Environmental Risk Variables. (United States)

    Morton, Sarah E; O'Hare, Kirstie J M; Maha, Jaimee L K; Nicolson, Max P; Machado, Liana; Topless, Ruth; Merriman, Tony R; Linscott, Richard J


    Meehl regarded schizotypy as a categorial liability for schizophrenia that is the product of genes, environment, and gene-environment interactions. We sought to test whether schizophrenia-related genotypes and environmental risk factors predict membership in classes defined by taxometric analyses of positive (cognitive-perceptual), negative (interpersonal), and disorganized schizotypy. Participants (n = 500) completed the Schizotypal Personality Questionnaire (SPQ) and provided information on the following risk factors: cannabis use, pregnancy and obstetric complications, social adjustment, and family history of psychosis. Saliva samples were obtained so that the frequency of single-nucleotide polymorphism (SNP) alleles associated with risk for developing schizophrenia could be determined. Genotyped SNPs were rs1625579 (MIR137), rs7004633 (MMP16), rs7914558 (CNNM2), and rs12966547 (CCDC68). Sets of SPQ items were subject to multiple coherent cut kinetic (CCK) analyses, including mean-above-minus-below-a-cut, maximum covariance, maximum eigenvalue, and latent modes analyses. CCK analyses indicated latent taxonicity of schizotypy across the 3 item sets. The cognitive-perceptual class had a base rate of 25%, and membership was predicted by the rs7004633 SNP (odds ratio = 2.33, 95% confidence interval = 1.15-4.72 in adjusted analyses). Poor social adjustment predicted memberships in the interpersonal (16%) and disorganized (21%) classes. Classes were found not to be mutually exclusive. Schizotypy is taxonic and schizotypy class membership is predicted by genetic and environmental factors that predict schizophrenia. The findings hold the promise that a more complete understanding of schizotypy as a schizophrenia liability state will come from investigation of other genes and environmental factors associated with schizophrenia. © The Author 2016.

  10. Rating Pregnancy Wheel Applications Using the APPLICATIONS Scoring System. (United States)

    Chyjek, Kathy; Farag, Sara; Chen, Katherine T


    To identify the top-rated pregnancy wheel applications (apps) using a newly developed APPLICATIONS scoring system. A list of pregnancy wheel apps was identified. Consumer-based and inaccurate apps were excluded. The APPLICATIONS scoring system was developed to rate the remaining apps. Application comprehensiveness was evaluated. Objective rating components included price, paid subscription, literature used, in-app purchases, connectivity to the Internet, advertisements, text search field, interdevice compatibility, and other components such as images or figures, videos, and special features. Subjective rating components were ease of navigation and subjective presentation. A complete list of 55 pregnancy wheel apps was created from three sources. Thirty-nine (71%) were consumer-based, inaccurate, or both, leaving 16 (29%) for analysis using the APPLICATIONS scoring system. More than two thirds of pregnancy wheel apps were excluded from our study secondary to being consumer-based, inaccurate, or both. This highlights the importance of identifying systematically, reviewing critically, and rating the thousands of available apps to health care providers to ensure accuracy and applicability. We propose that our APPLICATIONS scoring system be used to rate apps in all specialties with the goal of improving health care provider performance and thereby patient outcomes. III.

    We describe a conceptually simple algorithm for assigning judgement scores to rhythmic gymnastic movements, which could improve scoring objectivity and reduce judgemental bias during competitions. Our method, implemented as a real-time computer vision software, takes a video shot or a live performance video stream as input and extracts detailed velocity field information from body movements, transforming them into specialized spatio-temporal image templates. The collection of such images over time, when projected into a velocity covariance eigenspace, trace out unique but similar trajectories for a particular gymnastic movement type. By comparing separate executions of the same atomic gymnastic routine, our method assigns a quality judgement score that is related to the distance between the respective spatio-temporal trajectories. For several standard gymnastic movements, the method accurately assigns scores that are comparable to those assigned by expert judges. We also describe our rhythmic gymnastic video shot database, which we have made freely available to the human movement research community.

  17. Using Minimum Acceptable GRE Scores for Graduate Admissions Suppresses Diversity (United States)

    Miller, Casey


    I will present data showing that significant performance disparities on the GRE general test exist based on the test taker's race and gender [1]. Because of the belief that high GRE scores qualify one for graduate studies, the diversity issues faced by STEM fields may originate, at least in part, in misuse of the GRE scores by graduate admissions committees. I will quantitatively demonstrate this by showing that the combination of a hard cut-off and the different score distributions leads to the systematic underrepresentation of certain groups. I will present data from USF’s PhD program that shows a lack of correlation between GRE scores and research ability; similar null results are emerging from numerous other programs. I will then discuss how assessing non-cognitive competencies in the selection process may lead to a more enlightened search for the next generation of scientists. [1] C. W.

  1. Semi-automatic sleep EEG scoring based on the hypnospectrogram. (United States)

    Koupparis, Andreas M; Kokkinos, Vasileios; Kostopoulos, George K


    Sleep EEG organization is revealed by sleep scoring, a time-consuming process based on strictly defined visual criteria. We explore the possibility of sleep scoring using the whole-night time-frequency analysis, termed hypnospectrogram, with a computer-assisted K-means clustering method. Hypnograms were derived from 10 whole-night sleep EEG recordings using either standard visual scoring under the Rechtshaffen and Kales criteria or semi-automated analysis of the hypnospectrogram derived from a single EEG electrode. We measured substantial agreement between the two approaches with Cohen's kappa considering all 7 stages at 0.61. A number of existing automated procedures have reached the level of human inter-rater agreement using the standard criteria. However, our approach offers the scorer the opportunity to exploit the information-rich graphic representation of the whole night sleep upon which the automated method works. This work suggests that the hypnospectrogram can be used as an objective graphical representation of sleep architecture upon which sleep scoring can be performed with computer-assisted methods.

  3. Diffusion abnormality maps in demyelinating disease: correlations with clinical scores. (United States)

    Onu, Mihaela; Roceanu, Adina; Sboto-Frankenstein, Uta; Bendic, Robert; Tarta, Eugen; Preoteasa, Florentin; Bajenaru, Ovidiu


    Magnetic resonance imaging (MRI) has been explored as a noninvasive tool to assess pathology in multiple sclerosis (MS) patients. However, the correlation between classical MRI measures and physical disability is modest in MS. The diffusion tensor imaging (DTI) MRI technique holds particular promise in this regard. The present study shows brain regions where FA and individual diffusivities abnormalities are present and check their correlations with physical disability clinical scores. Eight patients and 12 matched healthy controls were recruited. The Multiple Sclerosis Functional Composite was administered. For MR-DTI acquisitions, a Genesis Signa 1.5 T MR system, an EP/SE scanning sequence, 25 gradient directions were used. Tract Based Spatial Statistics (TBSS) group comparisons showed reduced FA and increased individual diffusivities in several brain regions in patients. Significant correlations were found between FA and: EDSS, 9-HPT(NON)DOM and 25 FW score; between λ2 and: P100 (r&l), 9-HPT(NON)DOM and 25 FW; between λ3 and: 9-HPT(NON)DOM and 25 FW score. Fractional anisotropy and individual radial diffusivities proved to be important markers of motor disabilities in MS patients when the disease duration mean and the disability scores values range are relatively high.

(SNL-NM), Albuquerque, NM (United States)


    The purpose of the Scope, Complexity, Options, Risks, Excursions (SCORE) model is to estimate the relative complexity of design variants of future warhead options, resulting in scores. SCORE factors extend this capability by providing estimates of complexity relative to a base system (i.e., all design options are normalized to one weapon system). First, a clearly defined set of scope elements for a warhead option is established. The complexity of each scope element is estimated by Subject Matter Experts (SMEs), including a level of uncertainty, relative to a specific reference system. When determining factors, complexity estimates for a scope element can be directly tied to the base system or chained together via comparable scope elements in a string of reference systems that ends with the base system. The SCORE analysis process is a growing multi-organizational Nuclear Security Enterprise (NSE) effort, under the management of the NA-12 led Enterprise Modeling and Analysis Consortium (EMAC). Historically, it has provided the data elicitation, integration, and computation needed to support the out-year Life Extension Program (LEP) cost estimates included in the Stockpile Stewardship Management Plan (SSMP).

    Irradiation mucositis is defined as an inflammatory-like process of the oropharyngeal mucosa following therapeutic irradiation of patients who have head and neck cancer. Clinically, it is a serious side effect because severe mucositis can cause generalized problems (weight loss, nasogastic tube feedings) and interferes with the well-being of the patient seriously. Grading mucositis is important for the evaluation of preventive and therapeutic measures. The object of this study was to develop a scoring method based on local mucositis signs only. Four clinical local signs of mucositis were used in this score: white discoloration, erythema, pseudomembranes and ulceration. Mucositis of the oral cavity was calcualted during conventional irradiation protocol for 8 distinguishable areas using the 4 signs and their extent. A prospective evaluation of this method in 15 irradiated head and neck cancer patients displayed an S-curve reflecting a symptomless first irradiation week, followed by a rapid and steady increase of white discoloration, erythema and pseudomembranes during the second and third week. Oral candidiasis, generalized symptoms such as weight loss and the highest mucositis scores were seen after 3 weeks irradiation. The novel mucositis scoring method may be of value in studying the effect of hygiene programs, topical application of disinfectans or antibiotics on oral mucositis. (author).

MetS has traditionally been classified based on dichotomous criteria that deny that MetS-related risk likely exists as a spectrum. Continuous MetS scores provide a way to track MetS-related risk over time. We generated MetS severity scores that are sex- and race/ethnicity-specific, acknowledging that the way MetS is manifested may be different by sex and racial/ethnic subgroup. These scores are correlated with long-term risk for type 2 diabetes mellitus and cardiovascular disease. Clinical use of scores like these provide a potential opportunity to identify patients at highest risk, motivate patients toward lifestyle change, and follow treatment progress over time.

    Liu, Feng; Mao, Ji-Ping; Yan, Xiang


    To evaluate the application value of Toronto clinical scoring system (TCSS) and its grading of neuropathy for diabetic peripheral neuropathy (DPN), and to explore the relationship between TCSS grading of neuropathy and the grading of diabetic nephropathy and diabetic retinopathy. A total of 209 patients of Type 2 diabtes (T2DM) underwent TCSS. Taking electrophysiological examination as a gold standard for diagnosing DPN, We compared the results of TCSS score > or = 6 with electrophysiological examination, and tried to select the optimal cut-off points of TCSS. The corresponding accuracy, sensitivity, and specificity of TCSS score > or = 6 were 76.6%, 77.2%, and 75.6%, respectively.The Youden index and Kappa were 0.53 and 0.52, which implied TCSS score > or = 6 had a moderate consistency with electrophysiological examination. There was a linear positive correlation between TCSS grading of neuropathy and the grading of diabetic nephropathy and diabetic retinopathy (P<0.05). The optimal cut-off point was 5 or 6 among these patients. TCSS is reliable in diagnosing DPN and its grading of neuropathy has clinical value.

    Full Text Available BINUS students are supposed to increase their English competence indicated by their TOEFL scores. This paper aims to observe the differences between studens TOEFL scores obtained when they entered BINUS and the scores after they joined TOEFL courses at BINUS for one year. The participants were 121 students. The data for the entrance test were taken from the BINUS data center and the final test data were taken from their final test at English class. The data were analysed using statistics especially the descriptive statistics, comparing means, and correlation. To support the quantative data, a set of questionnaires was distributed to those 121 students. The results show that the students’ TOEFL scores have increased significantly in the final test compared to those in the entrance test. The low achiever students showed a better performance than the higher ones. Students’ motivation and background support their English study. Students proved to have the most problem in listening. The results of the research are expected to be the input for English lecturers to improve their teaching especially the existence of SALLC (Self Access Language Learning Center.

  12. Clinical scoring and instrumental analysis to evaluate skin types. (United States)

    Mercurio, D G; Segura, J H; Demets, M B A; Maia Campos, P M B G


    The biology of the skin is very complex, and there are a number of methods used to classify the different skin types. It is possible to measure or quantify the characteristics of the specific skin types, using a variety of techniques that can objectively evaluate the properties of the skin in a noninvasive manner. To clinically characterize different skin types by dermatological evaluation and biophysical and skin imaging techniques, and to evaluate the relationship between the different characteristics. The study recruited 26 volunteers. Clinical scoring was performed by a dermatologist who classified the volunteers' skin as normal or dry (group 1) and combination or oily (group 2). Objective measurements included skin microrelief, pH, oiliness, water content of the stratum corneum and transepidermal water loss (TEWL). Positive correlations were found between the level of skin oiliness and skin texture obtained from both instrumental analysis and clinical scoring. The combination and oily skin types had higher clinical scores for shine intensity, oiliness and tendency to pigmentation, and also had higher objective scores for sebum secretion, TEWL and roughness. Biophysical and skin imaging techniques are effective tools to help characterize skin type and assist in clinical dermatology. We found that different skin types had different characteristics related to skin microrelief, oiliness and TEWL, and therefore require specific dermatological treatments. © The Author(s) CED © 2013 British Association of Dermatologists.

    DREAM challenges are community competitions designed to advance computational methods and address fundamental questions in system biology and translational medicine. Each challenge asks participants to develop and apply computational methods to either predict unobserved outcomes or to identify unknown model parameters given a set of training data. Computational methods are evaluated using an automated scoring metric, scores are posted to a public leaderboard, and methods are published to facilitate community discussions on how to build improved methods. By engaging participants from a wide range of science and engineering backgrounds, DREAM challenges can comparatively evaluate a wide range of statistical, machine learning, and biophysical methods. Here, we describe DREAMTools, a Python package for evaluating DREAM challenge scoring metrics. DREAMTools provides a command line interface that enables researchers to test new methods on past challenges, as well as a framework for scoring new challenges. As of March 2016, DREAMTools includes more than 80% of completed DREAM challenges.

    The International Parkinson and Movement Disorder Society-sponsored UPDRS (MDS-UPDRS) is a powerful clinical outcome measure. To evaluate the feasibility of various MDS-UPDRS-based composite scores and determine their minimal clinically important difference threshold values. Overall, 1,113 paired investigations of 452 patients were reviewed implementing three different techniques simultaneously. Based on the ordinal regression modeling, the MDS-UPDRS II+III, MDS-UPDRS I+II+III, and the total score of MDS-UPDRS are clinically applicable outcome measures. Any improvement greater than 4.9 points or any worsening more than 4.2 points on MDS-UPDRS II+III represent a minimal, yet clinically meaningful, change. In reference to MDS-UPDRS I+II+III, the smallest changes considered clinically relevant were 6.7 and 5.2 points for improvement and deterioration, respectively. The thresholds for the total score of MDS-UPDRS were 7.1 points for improvement and 6.3 points for worsening. Our findings support the application of various MDS-UPDRS-based composite scores. © 2018 International Parkinson and Movement Disorder Society. © 2018 International Parkinson and Movement Disorder Society.

  20. Correlation of scores on the Eysenck and SONSO Personality inventories. (United States)

    Kentle, R L


    Correlations of scores on the Eysenck Personality Inventory with those of the SONSO Personality Inventory, a test of five factors of personality, were estimated for 300 junior college students. Extraversion and Neuroticism show reasonably close correspondence to the Shyness and Nervousness scales of the SONSO.
