    The objective of this study was to present the computerized structure that enables the use of the Nursing Activities Score (NAS) in mobile technology. It is a project for the development of technology production based on software engineering, founded on the theory of systems development life cycle. The NAS system was built in two modules: the search module, which is accessed using a personal computer (PC), and Data Collection module, which is accessed through a mobile device (Smartphone). The NAS system was constructed to allow other forms, in addition to the NAS tool, to be included in the future. Thus, it is understood that the development of the NAS will bring nurses closer to mobile technology and facilitate their accessibility to the data of the instrument relating to patients, thus assisting in decision-making and in staffing to provide nursing care.

    2013-01-01

    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 ...

  9. Why mental arithmetic counts: brain activation during single digit arithmetic predicts high school math scores.

    Price, Gavin R; Mazzocco, Michèle M M; Ansari, Daniel

    2013-01-01

    Do individual differences in the brain mechanisms for arithmetic underlie variability in high school mathematical competence? Using functional magnetic resonance imaging, we correlated brain responses to single digit calculation with standard scores on the Preliminary Scholastic Aptitude Test (PSAT) math subtest in high school seniors. PSAT math scores, while controlling for PSAT Critical Reading scores, correlated positively with calculation activation in the left supramarginal gyrus and bilateral anterior cingulate cortex, brain regions known to be engaged during arithmetic fact retrieval. At the same time, greater activation in the right intraparietal sulcus during calculation, a region established to be involved in numerical quantity processing, was related to lower PSAT math scores. These data reveal that the relative engagement of brain mechanisms associated with procedural versus memory-based calculation of single-digit arithmetic problems is related to high school level mathematical competence, highlighting the fundamental role that mental arithmetic fluency plays in the acquisition of higher-level mathematical competence.

  11. Schizotypal perceptual aberrations of time: correlation between score, behavior and brain activity.

    Shahar Arzy

    Full Text Available A fundamental trait of the human self is its continuum experience of space and time. Perceptual aberrations of this spatial and temporal continuity is a major characteristic of schizophrenia spectrum disturbances--including schizophrenia, schizotypal personality disorder and schizotypy. We have previously found the classical Perceptual Aberration Scale (PAS scores, related to body and space, to be positively correlated with both behavior and temporo-parietal activation in healthy participants performing a task involving self-projection in space. However, not much is known about the relationship between temporal perceptual aberration, behavior and brain activity. To this aim, we composed a temporal Perceptual Aberration Scale (tPAS similar to the traditional PAS. Testing on 170 participants suggested similar performance for PAS and tPAS. We then correlated tPAS and PAS scores to participants' performance and neural activity in a task of self-projection in time. tPAS scores correlated positively with reaction times across task conditions, as did PAS scores. Evoked potential mapping and electrical neuroimaging showed self-projection in time to recruit a network of brain regions at the left anterior temporal cortex, right temporo-parietal junction, and occipito-temporal cortex, and duration of activation in this network positively correlated with tPAS and PAS scores. These data demonstrate that schizotypal perceptual aberrations of both time and space, as reflected by tPAS and PAS scores, are positively correlated with performance and brain activation during self-projection in time in healthy individuals along the schizophrenia spectrum.

  16. Reliability of Accelerometer Scores for Measuring Sedentary and Physical Activity Behaviors in Persons With Multiple Sclerosis.

    Klaren, Rachel E; Hubbard, Elizabeth A; Zhu, Weimo; Motl, Robert W

    2016-04-01

    This brief research note examined the reliability of scores from an accelerometer as measures of sedentary and physical activity behaviors in persons with multiple sclerosis (MS). The analysis was performed on a combined data set from 2 previous longitudinal investigations of physical activity in MS. We focused on the number of days required to reliably estimate sedentary behavior, based on time spent in sedentary behavior per day and number of sedentary breaks, number of long sedentary bouts, and average length of sedentary bouts per day. We further examined the number of days required to reliably estimate physical activity behavior, based on time spent in light and moderate-to-vigorous physical activity and average length of activity bouts per day. Between 4-6 days of monitoring and 3-7 days of monitoring were necessary for good reliability of scores from all sedentary outcomes and physical activity outcomes, respectively. These results should guide research and practice examining sedentary and physical activity behaviors using accelerometry in persons with MS. PMID:27078272

    2015-09-01

    Full Text Available Introduction: Physical activity has become an important intervention against overweight and obesity cases in the USA and worldwide. One key aspect of physical activity is walking, which has been identified as a component that can easily be incorporated into one’s lifestyle. Recent studies on physical activity have focused on promoting walking as a health enhancing endeavor. In 2010, the proportion of Texas adults who reported no participation in leisure time activity (26.7% was significantly higher than the national average (24.4%. However, many Texans, like most Americans, are sedentary. Purpose: This study examined the walkability of the environments in selected counties in east Texas including Wood, Van Zandt and Smith counties. Methods and material: The data was drawn from the Walkscore.com and was based on all the zip codes in the three counties in east Texas. The community capitals were used a framework for analysis.  Results: Only three (8.82% zip codes had walkable scores between 70 and 89; five (14.71% had scores between 50 and 69; four (11.76% between 25 and 49 and 22 (64.71% had a score below 24. Discussion: The vast majority (26, 76.47% of zip codes are highly dependent on vehicle transport. Conclusions and recommendations: Stakeholders need therefore to focus on causes for the minimal walkability so that practical interventions are generated to enhance the physical activity friendly infrastructure so as to enhance the well-being of the residents in these three east Texas counties.

    Several multi-item activities of daily living (ADL) scales have been developed for assessment of functional status of patients with Alzheimer’s Disease (AD) in the last few decades. A disadvantage of the large number of scales is that scores of different ADL scales cannot be compared directly with each other. ADL scales which are used by McNamee’s (Townsend's disability scale) and Hill’s (Medicare Beneficiary definitions and Katz index of ADL) provide suitable tools for modelling the cost-eff...

  2. Alimentary Habits, Physical Activity, and Framingham Global Risk Score in Metabolic Syndrome

    Metabolic syndrome is a complex disorder represented by a set of cardiovascular risk factors. A healthy lifestyle is strongly related to improve Quality of Life and interfere positively in the control of risk factors presented in this condition. To evaluate the effect of a program of lifestyle modification on the Framingham General Cardiovascular Risk Profile in subjects diagnosed with metabolic syndrome. A sub-analysis study of a randomized clinical trial controlled blind that lasted three months. Participants were randomized into four groups: dietary intervention + placebo (DIP), dietary intervention + supplementation of omega 3 (fish oil 3 g/day) (DIS3), dietary intervention + placebo + physical activity (DIPE) and dietary intervention + physical activity + supplementation of omega 3 (DIS3PE). The general cardiovascular risk profile of each individual was calculated before and after the intervention. The study included 70 subjects. Evaluating the score between the pre and post intervention yielded a significant value (p < 0.001). We obtained a reduction for intermediate risk in 25.7% of subjects. After intervention, there was a significant reduction (p < 0.01) on cardiovascular age, this being more significant in groups DIP (5.2%) and DIPE (5.3%). Proposed interventions produced beneficial effects for reducing cardiovascular risk score. This study emphasizes the importance of lifestyle modification in the prevention and treatment of cardiovascular diseases

  3. Disease activity score in rheumatoid arthritis with or without secondary fibromyalgia

    Objective: To correlate disease activity score (DAS-28) in the patients with rheumatoid arthritis (RA) with and without secondary fibromyalgia. Study Design: Comparative cross-sectional study. Place and Duration of Study: Department of Rheumatology, Pakistan Institute of Medical Sciences, Islamabad, from November 2011 to April 2012. Methodology: Patients aged above 16 years diagnosed to have rheumatoid arthritis according to ACR/EULAR criteria 2010 were included in the study. Fibromyalgia (FM) was diagnosed by ACR 1990 criteria. Patients of other autoimmune diseases or psychiatric illnesses were excluded. DAS was determined and compared using t-test with significance at p < 0.05. Results: The mean age of study subjects was 42.9 years. Thirty one out of total 138 patients had fibromyalgia (22.4%). Female gender was predominant (92.0%); being 96.8% in patients with and in 88.2% without fibromyalgia. The average DAS score was high (5.3 + 1.5) in fibromyalgia patients compared to those without fibromyalgia (3.9 + 1.2); this difference in mean value was statistically significant (p = < 0.001). Conclusion: DAS-28 is a useful tool for assessing rheumatoid arthritis disease status in outpatient setting, however, increased disease activity must be assessed for possible co-existence of fibromyalgia which can spuriously give high DAS value and adversely affect treatment decision.

  7. Evaluation of Crohn's disease activity: Initial validation of a magnetic resonance enterography global score (MEGS) against faecal calprotectin

    To develop an MRI enterography global score (MEGS) of Crohn's disease (CD) activity compared with a reference standard of faecal calprotectin (fC), C-reactive protein (CRP) and Harvey-Bradshaw index (HBI). Calprotectin, CRP and HBI were prospectively recorded for 71 patients (median age 33, male 35) with known/suspected CD undergoing MRI enterography. Two observers in consensus scored activity for nine bowel segments, grading mural thickness, T2 signal, mesenteric oedema, T1 enhancement and pattern, and haustral loss. Segmental scores were multiplied according to disease length. Five points each were added for lymphadenopathy, comb sign, fistulae and abscesses to derive the MEGS. A previously validated MRI CD activity score (CDAS) was also calculated. MRI scores were correlated with clinical references using Spearman's rank. A logistic regression diagnostic model was built to discriminate active (fC > 100 μg/g) from inactive disease. MEGS and CDAS were significantly correlated with fC (r = 0.46, P < 0.001) and (r = 0.39, P = 0.001) respectively. MEGS correlated with CRP (r = 0.39, P = 0.002). The model for discriminating active from inactive disease achieved an area under the receiver-operating curve of 0.75 and 0.66 after leave-one-out analysis. A magnetic resonance enterography global score (MEGS) of CD activity correlated significantly with fC levels. (orig.)

    Full Text Available Estudou-se a aplicação do conceito de "risco" na área materno-infantil, partindo da proposta da Organização Mundial de Saúde relativa ao "enfoque de risco" na organização dos serviços de saúde. O estudo concentrou-se no desenvolvimento de instrumentos de identificação de grupos de alto risco de óbito infantil, seja no período neonatal, seja no período pós-neonatal, e baseou-se em estudo de caso-controle. O grupo de casos correspondeu a óbitos registrados de menores de um ano de idade, ocorridos nos anos de 1984 e 1985, de pais residentes nos municípios de Cotia e Vargem Grande Paulista, SP (Brasil, totalizando 149 óbitos (casos. O grupo controle foi formado por uma amostra probabilística de 216 crianças nascidas em 1984, filhas de pais residentes nos municípios estudados e que sobreviveram ao primeiro ano de vida, As mães de ambos os grupos responderam a um questionário, aplicado em entrevistas domiciliarias, para a identificação de variáveis independentes associadas ao óbito infantil. As variáveis que mostraram associação estatisticamente significante foram agrupadas em quatro escalas de risco: para uso em pré-natal; para uso por ocasião do parto; para uso no período neonatal; e para uso em puericultura após o período neonatal. As variáveis participaram nas escalas ponderadas pelos valores das razões dos produtos cruzados. As escalas apresentaram diferentes pontos de corte e a cada um destes correspondeu uma dada sensibilidade, especificidade e poder preditivo.The application of the concept of "risk" to maternal and child health was studied, the starting point being the World Health Organization's proposal for a "risk approach" in health services.

    Conclusion The circulating IL-18 and IL-10 concentrations were significantly elevated in SLE patients and correlated with the SLEDAI score. The study emphasized that there exists an upregulated proinflammatory as well as anti-inflammatory responses in patients with active SLE; however, the anti-inflammatory response is not enough to suppress the active disease. Identifying the exact contribution of the currently studied cytokines might provide future insights for targeted therapeutic strategies in SLE.

    Full Text Available Indirect immunofluorescence (IIF has been used to identify and measure autoantibody levels in pemphigus vulgaris but data about relationship between clinical severity of disease and antibody titers by IIF have been conflicting. We conducted this cross-sectional study to correlate the severity of oral and/or cutaneous involvement in patients with pemphigus vulgaris based on Pemphigus Area and Activity Score with IIF titers. Sixty-one new pemphigus vulgaris patients were included in this study. Human prepuce was used as substrate for IIF and assessment of disease severity was based on Pemphigus Area and Activity Score. The mean±SD age was 44.04±30.46 years, with a range of 18 to 79 years. IIF was positive in 56 (91.8% patients. There was a significant relationship between total disease score and IIF titers ((P<0.001. Also a significant relationship was found between skin score (P=0.04 and mucosal score (P=0.04 with IIF titers. Our results show that there is a significant relationship between disease activity based on Pemphigus Area and Activity Score and antibody titers by IIF. Further studies are recommended to determine the usefulness of this technique for monitoring disease.

    Full Text Available Background. Prostate cancer is the most common noncutaneous cancer and second leading cause of cancer-related mortality in men in the US. Growing evidence suggests that oxidative stress is involved in prostate cancer. Methods. In this study, thioredoxin 1 (Trx 1, an enzyme and subcellular indicator of redox status, was measured in prostate biopsy tissue from 55 men from the North Carolina-Louisiana Prostate Cancer Project. A pathologist blindly scored levels of Trx 1. The association between Trx 1 and the Gleason score, erythrocyte antioxidant enzyme activity, and dietary antioxidant intake was determined using Fisher’s exact test. Results. Trx 1 levels in benign prostate tissue in men with incident prostate cancer were positively associated with the Gleason score (P=0.01 and inversely associated with dietary antioxidant intake (P=0.03. In prostate cancer tissue, Trx 1 levels were associated with erythrocyte glutathione peroxidase activity (P=0.01. No association was found for other erythrocyte enzymes. Greater Gleason score of malignant tissue corresponds to a greater difference in Trx 1 levels between malignant and benign tissue (P=0.04. Conclusion. These results suggest that the redox status of prostate tissue is associated with prostate cancer grade and both endogenous and exogenous antioxidants.

    Pathologists provide diagnoses relevant to the disease state of the patient and identify specific tissue characteristics relevant to response to therapy and prognosis. As personalized medicine evolves, there is a trend for increased demand of tissue-derived parameters. Pathologists perform increasingly complex analyses on the same 'cases'. Traditional methods of workload assessment and reimbursement, based on number of cases sometimes with a modifier (eg, the relative value unit (RVU) system used in the United States), often grossly underestimate the amount of work needed for complex cases and may overvalue simple, small biopsy cases. We describe a new approach to pathologist workload measurement that aligns with this new practice paradigm. Our multisite institution with geographically diverse partner institutions has developed the Automatable Activity-Based Approach to Complexity Unit Scoring (AABACUS) model that captures pathologists' clinical activities from parameters documented in departmental laboratory information systems (LISs). The model's algorithm includes: 'capture', 'export', 'identify', 'count', 'score', 'attribute', 'filter', and 'assess filtered results'. Captured data include specimen acquisition, handling, analysis, and reporting activities. Activities were counted and complexity units (CUs) generated using a complexity factor for each activity. CUs were compared between institutions, practice groups, and practice types and evaluated over a 5-year period (2008-2012). The annual load of a clinical service pathologist, irrespective of subspecialty, was ∼40,000 CUs using relative benchmarking. The model detected changing practice patterns and was appropriate for monitoring clinical workload for anatomical pathology, neuropathology, and hematopathology in academic and community settings, and encompassing subspecialty and generalist practices. AABACUS is objective, can be integrated with an LIS and automated, is reproducible, backwards compatible

    The investigation of the complex processes involved in cellular differentiation must be based on unbiased, high throughput data processing methods to identify relevant biological pathways. A number of bioinformatics tools are available that can generate lists of pathways ranked by statistical significance (i.e. by p-value), while ideally it would be desirable to functionally score the pathways relative to each other or to other interacting parts of the system or process. We describe a new computational method (Network Activity Score Finder - NASFinder) to identify tissue-specific, omics-determined sub-networks and the connections with their upstream regulator receptors to obtain a systems view of the differentiation of human adipocytes. Adipogenesis of human SBGS pre-adipocyte cells in vitro was monitored with a transcriptomic data set comprising six time points (0, 6, 48, 96, 192, 384 hours). To elucidate the mechanisms of adipogenesis, NASFinder was used to perform time-point analysis by comparing each time point against the control (0 h) and time-lapse analysis by comparing each time point with the previous one. NASFinder identified the coordinated activity of seemingly unrelated processes between each comparison, providing the first systems view of adipogenesis in culture. NASFinder has been implemented into a web-based, freely available resource associated with novel, easy to read visualization of omics data sets and network modules.

  19. Effects of type of physical exercise and leisure activities on the depression scores of obese Brazilian adolescent girls

    2005-11-01

    Full Text Available Several studies have indicated that depressive states may lead to hypokinesia with diminished metabolic rate and energy use. Hypokinesia associated with certain eating behaviors may lead to an unfavorable energy balance that can contribute to the emergence and prevalence of obesity among children and adults. The purpose of the present study was to examine the possibility of reducing depression inventory scores in female adolescents with third-degree obesity while testing the effectiveness of different exercise programs in reducing anxiety and depression scores. The sample consisted of 40 female subjects (mean age 16 ± 1.56 years divided into 4 groups (aerobic training, anaerobic training, leisure activities, and control. Subjects had a body mass index of 95% or more in relation to the 50th percentile. The aerobic program consisted of three ergometric bicycle sessions per week over a 3-month period (12 weeks and the activities were prescribed after determining the anaerobic ventilatory threshold (VO2 threshold. Anaerobic training was based on the Wingate anaerobic power test. The leisure program consisted of a varied range of activities (games, exercises, etc.. A nutritionist interviewed the members of these two groups and the control group every week in order to adapt them to the nutritional guidelines proposed for the study. The study showed that all three programs (aerobic exercise, anaerobic exercise and leisure activities were effective in reducing body mass. However, we found a significant reduction when analyzing the depression scores only for aerobic exercise (18.9 ± 9.33 to 10.6 ± 9.56 or 43.9% but no significant alterations for anaerobic exercise (11.36 ± 5.23 to 9.63 ± 4.78 or 15.22% and leisure (17.28 ± 7.55 to 15.07 ± 7.54 or 12.78%, thus indicating that in principle this type of activity could be included to improve emotional well-being of obese adolescent girls.

  1. Two new atom centered fragment descriptors and scoring function enhance classification of antibacterial activity.

    2014-04-01

    Classification of pharmacologic activity of a chemical compound is an essential step in any drug discovery process. We develop two new atom-centered fragment descriptors (vertex indices)--one based solely on topological considerations without discriminating atom or bond types, and another based on topological and electronic features. We also assess their usefulness by devising a method to rank and classify molecules with regard to their antibacterial activity. Classification performances of our method are found to be superior compared to two previous studies on large heterogeneous data sets for hit finding and hit-to-lead studies even though we use much fewer parameters. It is found that for hit finding studies topological features (simple graph) alone provide significant discriminating power, and for hit-to-lead process small but consistent improvement can be made by additionally including electronic features (colored graph). Our approach is simple, interpretable, and suitable for design of molecules as we do not use any physicochemical properties. The singular use of vertex index as descriptor, novel range based feature extraction, and rigorous statistical validation are the key elements of this study. PMID:24664120

    To develop an MRI enterography global score (MEGS) of Crohn's disease (CD) activity compared with a reference standard of faecal calprotectin (fC), C-reactive protein (CRP) and Harvey-Bradshaw index (HBI). Calprotectin, CRP and HBI were prospectively recorded for 71 patients (median age 33, male 35) with known/suspected CD undergoing MRI enterography. Two observers in consensus scored activity for nine bowel segments, grading mural thickness, T2 signal, mesenteric oedema, T1 enhancement and pattern, and haustral loss. Segmental scores were multiplied according to disease length. Five points each were added for lymphadenopathy, comb sign, fistulae and abscesses to derive the MEGS. A previously validated MRI CD activity score (CDAS) was also calculated. MRI scores were correlated with clinical references using Spearman's rank. A logistic regression diagnostic model was built to discriminate active (fC > 100 μg/g) from inactive disease. MEGS and CDAS were significantly correlated with fC (r = 0.46, P < 0.001) and (r = 0.39, P = 0.001) respectively. MEGS correlated with CRP (r = 0.39, P = 0.002). The model for discriminating active from inactive disease achieved an area under the receiver-operating curve of 0.75 and 0.66 after leave-one-out analysis. A magnetic resonance enterography global score (MEGS) of CD activity correlated significantly with fC levels. (orig.)

    2013-06-01

    Full Text Available Objective: To assess whether changes in dietary intake and physical activity pattern are associated with the annual body mass index (BMI z-score change among adolescents. Methods: The study was conducted in public schools in the city of Piracicaba, Sao Paulo, Brazil, with a probabilistic sample of 431 adolescents participating in wave I (2004 (hereafter, baseline and 299 in wave II (2005 (hereafter, follow-up. BMI, usual food intake, physical activity, screen time, sexual maturation and demographic variables were assessed twice. The association between annual change in food intake, physical activity, screen time, and annual BMI z-score changes were assessed by multiple regression. Results: The study showed a positive variation in BMI z-score over one-year. Among variables related to physical activity pattern only playing videogame and using computer increased over the year. The intake of fruits and vegetables and sugar-sweetened beverages increased over one year, while the others variables showed a reduction. An increased consumption of fatty foods (β = 0.04, p = 0.04 and sweetened natural fruit juices (β = 0.05, p = 0.03 was positively associated with the rise in BMI z-score. Conclusions: Unhealthy dietary habits can predict the BMI z-score gain more than the physical activity pattern. The intake of fatty foods and sweetened fruit juices is associated with the BMI z-score over one year.

  14. Activated TLR signaling in atherosclerosis among women with lower Framingham risk score: the multi-ethnic study of atherosclerosis.

    Chiang-Ching Huang

    Full Text Available BACKGROUND: Atherosclerosis is the leading cause of cardiovascular disease (CVD. Traditional risk factors can be used to identify individuals at high risk for developing CVD and are generally associated with the extent of atherosclerosis; however, substantial numbers of individuals at low or intermediate risk still develop atherosclerosis. RESULTS: A case-control study was performed using microarray gene expression profiling of peripheral blood from 119 healthy women in the Multi-Ethnic Study of Atherosclerosis cohort aged 50 or above. All participants had low (100 and carotid intima-media thickness (IMT >1.0 mm, whereas controls (N = 71 had CAC<10 and IMT <0.65 mm. We identified two major expression profiles significantly associated with significant atherosclerosis (odds ratio 4.85; P<0.001; among those with Framingham risk score <10%, the odds ratio was 5.30 (P<0.001. Ontology analysis of the gene signature reveals activation of a major innate immune pathway, toll-like receptors and IL-1R signaling, in individuals with significant atherosclerosis. CONCLUSION: Gene expression profiles of peripheral blood may be a useful tool to identify individuals with significant burden of atherosclerosis, even among those with low predicted risk by clinical factors. Furthermore, our data suggest an intimate connection between atherosclerosis and the innate immune system and inflammation via TLR signaling in lower risk individuals.

    2015-01-01

    The Annett Hand Preference Questionnaire (AHPQ) as modified by Briggs and Nebes was administered along with Carver and White's behavioural inhibition system (BIS) and behavioural activation system (BAS) scale and a shortened form of the Big Five personality questionnaire to 92 university students. After eliminating the data from five respondents who reported having changed handedness and one outlier, there was a significant sex difference in mean BIS scores, with females (n = 43) scoring higher than males (n = 43). Replicating the results of Wright, Hardie and Wilson, non-right-handers (n = 36) had significantly higher mean BIS score than right-handers (n = 50). Controlling for sex of participant, neuroticism and BAS sub-scale scores in hierarchical regression analyses left this BIS effect substantially unaffected. There was no handedness or sex difference on any of the three BAS sub-scales. Further analyses revealed no association between strength, as distinct from direction, of handedness and BIS (or BAS) scores. The findings are discussed with reference to recent developments in reinforcement sensitivity theory on which BIS/BAS variables are based. PMID:25697855

  19. Orbital magnetic resonance imaging combined with clinical activity score can improve the sensitivity of detection of disease activity and prediction of response to immunosuppressive therapy for Graves' ophthalmopathy

    The aim of this study was to demonstrate that the addition of orbital magnetic resonance (MR) imaging can provide improvement in sensitivity of detection of active disease and the prediction of the response to intravenous glucocorticoid therapy (ivGC), over clinical activity score (CAS) alone. A prospective case series was studied at our institution. Forty eight patients were examined by CAS and orbital MR imaging. The maximum of T2 relaxation times of extraocular muscles (maxT2RT) and other parameters were evaluated by MR imaging. Thirty five of 48 patients underwent ivGC. Twenty of 35 patients, whose CAS was 2 points or less, were evaluated for the response to ivGC. The correlation between CAS and maxT2RT was evaluated. Differentiation of active and inactive Graves' ophthalmopathy (GO) was performed by CAS and orbital MR imaging. The response to ivGC was evaluated by CAS, orbital MR imaging and ophthalmic parameters. As a result, CAS and maxT2RT showed significant positive correlation (r=0.58, p<0.0001), and 15 patients were positive by CAS and orbital MR imaging. However, 20 patients were positive by only MR imaging. In those 20 patients, there was significant improvement after ivGC. We concluded that orbital MR imaging combined with CAS could improve the sensitivity of detection of active disease and the prediction of the response to ivGC. In addition, even if only one parameter of CAS is positive, further examination with orbital MR imaging is advised. (author)

    BACKGROUND/OBJECTIVES Although the association of body mass index (BMI) with metabolic syndrome (MetS) is well documented, there is little knowledge on the independent and joint associations of BMI and physical activity with MetS risk based on a continuous scoring system. This study was designed to explore the effect of physical activity on interactions between excess body weight and continuous metabolic syndrome (cMetS) in a nationwide survey of Iranian children and adolescents. SUBJECTS/METHODS Data on 5,625 school students between 10 and 18 years of age were analyzed. BMI percentiles, screen time activity (STA), leisure time physical activity (LTPA) levels, and components of cMetS risk score were extracted. Standardized residuals (z-scores) were calculated for MetS components. Linear regression models were used to study the interactions between different combinations of cMetS, LTPA, and BMI percentiles. RESULTS Overall, 984 (17.5%) subjects were underweight, whereas 501 (8.9%) and 451 (8%) participants were overweight and obese, respectively. All standardized values for cMetS components, except fasting blood glucose level, were directly correlated with BMI percentiles in all models (P-trend < 0.001); these associations were independent of STA and LTPA levels. Linear associations were also observed among LTPA and standardized residuals for blood pressure, high-density lipoprotein, and waist circumference (P-trend < 0.01). CONCLUSIONS Our findings suggest that BMI percentiles are associated with cMetS risk score independent of LTPA and STA levels. PMID:26244080

Physical inactivity in COPD patients is a crucial risk factor for OP; the COPD assessment test (CAT is the newest assessment tool for the health status and daily activities of COPD patients. This study investigated the relationship among daily physical activity (DPA, CAT scores, and bone mineral density (BMD in COPD patients with or without OP. This study included 30 participants. Ambulatory DPA was measured using actigraphy and oxygen saturation by using a pulse oximeter. BMD was measured using dual-energy X-ray absorptiometry. OP was defined as a T-score (standard deviations from a young, sex-specific reference mean BMD less than or equal to -2.5 SD for the lumbar spine, total hip, and femoral neck. We quantified oxygen desaturation during DPA by using a desaturation index and recorded all DPA, except during sleep. COPD patients with OP had lower DPA and higher CAT scores than those of patients without OP. DPA was significantly positively correlated with (lumbar spine, total hip, and femoral neck BMD (r=0.399, 0.602, 0.438, respectively

  9. Fetal Biophysical Profile Scoring

    H.R. HaghighatKhah

    2009-01-01

    significance. Fetal breathing movements, amniotic fluid volume, and the non-stress test are the most powerful variables. For example, when the biophysical profile score is 2, the perinatal mortality varies between 428/1000 with only fetal movement present to 66/1000 if the non-stress test is reactive and all of the ultrasound parameters are absent (Manning 1990b. Some authors have, therefore, proposed utilization of a modified biophysical profile that incorporates only the non-stress test and amniotic fluid volume (Miller 1996. Although the positive predictive value of these 2 tests is equivalent to a biophysical profile score of 6, the perinatal mortality is still increased over a normal test score of 8 or 10 (Manning 1990b. The false positive rate with the modified biophysical profile score is also substantially higher. "nConclusions: The fetus expresses its well being or compromised status through a number of different biophysical activities that are controlled by different central nervous system centers. The utilization of the biophysical score for antepartum surveillance in high-risk patients has resulted in a reduction in perinatal mortality when compared to historical controls. The appropriate management of the viable fetus with an abnormal biophysical profile score may also decrease long-term neurological morbidity (Manning 1998. "nIt is unlikely that in the future additional variables will be added to the biophysical profile score. However, perhaps the incorporation of the fetal state (i.e., eye movements and Doppler flow studies of specific fetal vessels (umbilical artery, middle cerebral artery, ductus venosus will be incorporated into a complete assessment of the fetal condition "n "nTable 1.

    Objectives To better understand the effectiveness of xylitol in caries prevention in adults, and to attempt improved clinical trial efficiency. Methods As part of the Xylitol for Adult Caries Trial (X-ACT), non-cavitated and cavitated caries lesions were assessed in subjects who were experiencing the disease. The trial was a test of the effectiveness of 5 grams/day of xylitol, consumed by dissolving in the mouth five 1 gram lozenges spaced across each day, compared with a sucralose placebo. For this analysis, seeking trial efficiency, 538 subjects aged 21–80, with complete data for four dental examinations were selected from the 691 randomized into the three year trial, conducted at three sites. Acceptable inter and intra examiner reliability before and during the trial was quantified using the kappa statistic. Results The mean annualized non-cavitated plus cavitated lesion transition scores in coronal and root surfaces, from sound to carious favoured xylitol over placebo, during the three cumulative periods of 12, 24, and 33 months, but these clinically and statistically non-significant differences declined in magnitude over time. Restricting the present assessment to those subjects with a higher baseline lifetime caries experience showed possible but inconsistent benefit. Conclusions There was no clear and clinically relevant preventive effect of xylitol on caries in adults with adequate fluoride exposure when non-cavitated plus cavitated lesions were assessed. This conformed to the X-ACT trial result assessing cavitated lesions. Including non-cavitated lesion assessment in this full scale, placebo controlled, multi site, randomized, double blinded clinical trial in adults experiencing dental caries, did not achieve added trial efficiency or demonstrate practical benefit of xylitol.

  13. Decompositions of Proper Scores

    Bröcker, Jochen

    2008-01-01

    Scoring rules are an important tool for evaluating the performance of probabilistic forecasts. A popular example is the Brier score, which allows for a decomposition into terms related to the sharpness (or information content) and to the reliability of the forecast. This feature renders the Brier score a very intuitive measure of forecast quality. In this paper, it is demonstrated that all strictly proper scoring rules allow for a similar decomposition into reliability and sharpness related terms. This finding underpins the importance of proper scores and yields further credence to the practice of measuring forecast quality by proper scores. Furthermore, the effect of averaging multiple probabilistic forecasts on the score is discussed. It is well known that the Brier score of a mixture of several forecasts is never worse that the average score of the individual forecasts. This property hinges on the convexity of the Brier score, a property not universal among proper scores. Arguably, this phenomenon portends...

    2015-06-01

    Full Text Available Health-related quality of life (HRQL for nursing home residents is important, however, the concept of quality of life is broad, encompasses many domains and is difficult to assess in people with dementia. Basic activities of daily living (ADL are measured routinely in nursing homes using the Resident Assessment Instrument-Minimum Data Set Version 2.0 (RAI-MDS and Functional Independence Measure (FIM instrument. We examined the relationship between HRQL and ADL to assess the future possibility of ADL dependency level serving as a surrogate measure of HRQL in residents with dementia. To assess ADL, measures derived from the RAI-MDS and FIM data were gathered for 111 residents at the beginning of our study and at 6-month follow-up. Higher scores for independence in ADL were correlated with higher scores for a disease-specific HRQL measure, the Quality of Life—Alzheimer’s Disease Scale. Preliminary evidence suggests that FIM-assessed ADL is associated with HRQL for these residents. The associations of the dressing and toileting items with HRQL were particularly strong. This finding suggests the importance of ADL function in HRQL. The RAI-MDS ADL scales should be used with caution to evaluate HRQL.

    2011-04-01

    Full Text Available Cada vez es más necesario disponer de instrumentos de medida en el ámbito de la salud que se puedan utilizar en la práctica clínica e investigación. Para garantizar la calidad de su medición es imprescindible que los instrumentos sean sometidos a un proceso de validación. Este proceso consiste en adaptar culturalmente un instrumento al medio donde se quiere administrar y comprobar sus características psicométricas como: fiabilidad, validez, sensibilidad y factibilidad. Hay instrumentos de medida del ámbito de la salud, disponibles en otros idiomas pero sin validar al español. Además la metodología para validar un instrumento es poco conocida por profesionales sanitarios, lo que explica el uso indiscriminado de instrumentos sólo adaptados o validados de manera poco consistente. El objetivo de esta revisión es realizar una puesta al día del proceso de validación de un instrumento de medida de la salud y en qué consiste de manera práctica. La accesibilidad de instrumentos de evaluación adaptados culturalmente y validados en distintos idiomas facilitará comparar resultados obtenidos con el mismo instrumento y desarrollar estudios internacionales en distintas culturas.

  1. Fingerprinting of music scores

    Irons, Jonathan; Schmucker, Martin

    2004-06-01

    Publishers of sheet music are generally reluctant in distributing their content via the Internet. Although online sheet music distribution's advantages are numerous the potential risk of Intellectual Property Rights (IPR) infringement, e.g. illegal online distributions, disables any innovation propensity. While active protection techniques only deter external risk factors, additional technology is necessary to adequately treat further risk factors. For several media types including music scores watermarking technology has been developed, which ebeds information in data by suitable data modifications. Furthermore, fingerprinting or perceptual hasing methods have been developed and are being applied especially for audio. These methods allow the identification of content without prior modifications. In this article we motivate the development of watermarking and fingerprinting technologies for sheet music. Outgoing from potential limitations of watermarking methods we explain why fingerprinting methods are important for sheet music and address potential applications. Finally we introduce a condept for fingerprinting of sheet music.

  2. Neutrophil-lymphocyte ratio, pain perception, and disease activity score may serve as important predictive markers for sustained remission in rheumatoid arthritis

    Full Text Available The implementation of new treatment strategies based on current recommendations has enabled a greater number of patients with rheumatoid arthritis (RA to achieve remission. However, there are no definite predictors of sustained remission. Moreover, the absence of clear consensus on the time of withdrawal or reduction of treatment further adds to the treatment burden. This pilot study was intended to evaluate the prognostic potential of various RA-related parameters. All the enrolled subjects (n=124 were clinically evaluated on the basis of various parameters including age, gender, duration of illness before the initiation of disease-modifying anti-rheumatic drugs, tender and swollen joints (28 joints, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP, hemoglobin percentage, lymphocyte count, total white-blood cell counts, and neutrophil to lymphocyte ratio (NLR. Student’s t-test and discriminant function analysis were performed. The specificity of all parameters and their best possible cut-off to predict relapse were calculated using the receiver operating characteristic (ROC analysis. A significant difference in terms of pain perception, NLR, tendency to have a significant tender joint count and absolute lymphocyte counts was identified between the patients in sustained remission and those in relapse. The ROC analysis indicated that NLR was consistent in predicting remission. CRP, ESR, and/or disease activity score may not be very effective in differentiating patients with sustainable remission/low disease activity. NLR along with patient’s perception of pain may assist in predicting sustained remission.

    Objectives. To retrospectively compare the results of the MRIA (magnetic resonance index of activity) with a modified MRIA (mMRIA), which was calculated excluding from MRIA formula the data of relative contrast enhancement (RCE). Materials and Methods. MR-E and corresponding endoscopic records of 100 patients were reviewed. MRIA, mMRIA, and SES endoscopic index were calculated for all the patients. Namely, MRIA was calculated as follows: (1.5 × wall thickening + 0.02 × RCE + 5 × intramural edema + 10 × ulcers), while mMRIA was calculated with the modified formula (1.5 × wall thickening + 5 × intramural edema + 10 × ulcers). Results. Mean MRIA and mMRIA values were 19.3 and 17.68, respectively (p < 0.0001). A significant correlation (p < 0.0001) was observed between MRIA and mMRIA scores and between both MR indexes and SES (p < 0.0001). Conclusions. mMRIA was comparable to MRIA in the evaluation of disease activity in Crohn's disease. PMID:26759554

  17. Relationship between the climbing up and climbing down stairs domain scores on the FES-DMD, the score on the Vignos Scale, age and timed performance of functional activities in boys with Duchenne muscular dystrophy

    Lilian A. Y. Fernandes

    2014-12-01

    Full Text Available BACKGROUND: Knowing the potential for and limitations of information generated using different evaluation instruments favors the development of more accurate functional diagnoses and therapeutic decision-making. OBJECTIVE: To investigate the relationship between the number of compensatory movements when climbing up and going down stairs, age, functional classification and time taken to perform a tested activity (TA of going up and down stairs in boys with Duchenne muscular dystrophy (DMD. METHOD: A bank of movies featuring 30 boys with DMD performing functional activities was evaluated. Compensatory movements were assessed using the climbing up and going down stairs domain of the Functional Evaluation Scale for Duchenne Muscular Dystrophy (FES-DMD; age in years; functional classification using the Vignos Scale (VS, and TA using a timer. Statistical analyses were performed using the Spearman correlation test. RESULTS: There is a moderate relationship between the climbing up stairs domain of the FES-DMD and age (r=0.53, p=0.004 and strong relationships with VS (r=0.72, p=0.001 and TA for this task (r=0.83, p<0.001. There were weak relationships between the going down stairs domain of the FES-DMD-going down stairs with age (r=0.40, p=0.032, VS (r=0.65, p=0.002 and TA for this task (r=0.40, p=0.034. CONCLUSION: These findings indicate that the evaluation of compensatory movements used when climbing up stairs can provide more relevant information about the evolution of the disease, although the activity of going down stairs should be investigated, with the aim of enriching guidance and strengthening accident prevention. Data from the FES-DMD, age, VS and TA can be used in a complementary way to formulate functional diagnoses. Longitudinal studies and with broader age groups may supplement this information.

  18. Fatty acid composition in serum correlates with that in the liver and non-alcoholic fatty liver disease activity scores in mice fed a high-fat diet.

    Wang, Xing-He; Li, Chun-Yan; Muhammad, Ishfaq; Zhang, Xiu-Ying

    2016-06-01

    In this study, we investigated the correlation between the serum fatty acid composition and hepatic steatosis, inflammation, hepatocellular ballooning scores, and liver fatty acids composition in mice fed a high-fat diet. Livers were collected for non-alcoholic fatty liver disease score analysis. Fatty acid compositions were analysed by gas chromatography. Correlations were determined by Pearson correlation coefficient. Exposed to a high-fat diet, mice developed fatty liver disease with varying severity without fibrosis. The serum fatty acid variation became more severe with prolonged exposure to a high-fat diet. This variation also correlated significantly with the variation in livers, with the types of fatty acids corresponding to liver steatosis, inflammation, and hepatocellular ballooning scores. Results of this study lead to the following hypothesis: the extent of serum fatty acid variation may be a preliminary biomarker of fatty liver disease caused by high-fat intake. PMID:27179602

    2013-01-01

    Background Subjective assessment tools such as visual analog scales (VAS) or pain scores are commonly used to evaluate the intensity of chronic cancer-induced pain.However,their value is limited in some cases.We measured changes in VAS pain scores and salivary a-amylase (sAA) concentrations in cancer patients receiving radiotherapy for bone metastases to ascertain the correlation between these measures.Methods We enrolled 30 patients with bone metastases attending a single institution from June 2010 to March 2011.All patients with cancer-induced bone pain received radiation therapy (RT) at the same dose (30 Gy) and fractionation (3 Gy/ fraction,5 days/week) for palliative pain relief.We assessed heart rate (HR),systolic and diastolic blood pressures (DBP/SBP) and VAS pain scores before (d0) and after five (d5) and ten fractions (d10) of irradiation,sAA and salivary cortisol (SC)concentrations were measured using a portable analyzer and automated chemiluminescence analyzer,respectively.Results Radiotherapy markedly decreased VAS scores from (82.93±9.29) to (31.43±t16.73) mm (P <0.001) and sAA concentrations from (109.40±26.38) to (36.03±19.40) U/ml (P <0.001).Moreover,there was a significant correlation between these two indices (P <0.01,r=0.541).HR decreased by 6.5% after radiotherapy,but did not correlate with VAS scores (P >0.05).SC concentrations and BP did not change significantly during the study (P >0.05).Conclusions The significant correlation between sAA concentrations and VAS pain scores identified in these preliminary results suggests that this biomarker may be a valuable,noninvasive and sensitive index for the objective assessment of pain intensity in patients with cancer-induced bone pain.

    2007-11-01

    Full Text Available Abstract Background Clinical guidelines for the management of back pain frequently recommend 'manual therapy' as a first line intervention, with psychosocial screening and 'active rehabilitation' for those not improving at 6 weeks post onset. The potential for psychosocial factors to predict treatment response and therefore outcome has not been adequately explored. The purpose of this pilot study was to determine the feasibility of a study to compare manual therapy and active rehabilitation outcomes for subjects with sub-acute/chronic back pain, investigate whether any difference in outcome was related to psychosocial factors, and to inform the design of a main study. Methods A convenience sample of 39 patients with non-specific low back pain referred to the physiotherapy department of an acute NHS Trust hospital was recruited over a nine month period. Patients completed the Linton and Hallden psychological screening questionnaire (LH and were allocated to a low LH (105 or below or high LH (106 or above scoring group. The low or high LH score was used to sequentially allocate patients to one of two treatment groups – Manual Therapy comprising physiotherapy based on manual means as chosen by the treating therapist or Active Rehabilitation comprising a progressive exercise and education programme – with the first low LH scoring patient being allocated to active rehabilitation and the next to manual therapy and so on. Treatment was administered for eight sessions over a four-week period and outcome measures were taken at baseline and at four weeks. Measures used were the Roland Morris Questionnaire (RMQ, two components of the Short Form McGill (total pain rating index [PRI] and pain intensity via visual analogue scale [VAS], and the LH. Results The manual therapy group demonstrated a greater treatment effect compared with active rehabilitation for RMQ (mean difference 3.6, 95% CI 1.1 – 6.2, p = 0.006 and PRI (7.1, 95% CI 2.0 – 12.2, p = 0

    Full Text Available Background. There is a need for tools to assess dependency among persons with severe impairments. Objectives. The aim was to compare the Functional Independence Measure (FIM and the Northwick Park Dependency Score (NPDS, in a sample from in-patient rehabilitation. Material and Methods. Data from 115 persons (20 to 65 years of age with neurological impairments was gathered. Analyses were made of sensitivity, specificity, positive predictive value, and negative predictive value. Agreement of the scales was assessed with kappa and concordance with Goodman-Kruskal’s gamma. Scale structures were explored using the Rank-Transformable Pattern of Agreement (RTPA. Content validation was performed. Results. The sensitivity of the NPDS as compared to FIM varied between 0.53 (feeding and 1.0 (mobility and specificity between 0.64 (mobility and 1.0 (bladder. The positive predictive value varied from 0.62 (mobility to 1.0 (bladder, and the negative predictive value varied from 0.48 (bowel to 1.0 (mobility. Agreement between the scales was moderate to good (four items and excellent (three items. Concordance was good, with a gamma of −.856, an asymptotic error (ase of .025, and P<.000. The parallel reliability between the FIM and the NPDS showed a tendency for NPDS to be more sensitive (having more categories when dependency is high. Conclusion. FIM and NPDS complement each other. NPDS can be used as a measure for severely injured patients who are sensitive when there is a high need of nursing time.

  11. Credit Scoring Modeling

    Siana Halim

    2014-01-01

    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.

  16. A high-resolution computed tomography-based scoring system to differentiate the most infectious active pulmonary tuberculosis from community-acquired pneumonia in elderly and non-elderly patients

    The objective of this study was to use high-resolution computed tomography (HRCT) imaging to predict the presence of smear-positive active pulmonary tuberculosis (PTB) in elderly (at least 65 years of age) and non-elderly patients (18-65 years of age). Patients with active pulmonary infections seen from November 2010 through December 2011 received HRCT chest imaging, sputum smears for acid-fast bacilli and sputum cultures for Mycobacterium tuberculosis. Smear-positive PTB was defined as at least one positive sputum smear and a positive culture for M. tuberculosis. Multivariate logistic regression analyses were performed to determine the HRCT predictors of smear-positive active PTB, and a prediction score was developed on the basis of receiver operating characteristic curve analysis. Of 1,255 patients included, 139 were diagnosed with smear-positive active PTB. According to ROC curve analysis, the sensitivity, specificity, positive predictive value, negative predictive value, false positive rates and false negative rates were 98.6 %, 95.8 %, 78.5 %, 99.8 %, 4.2 % and 1.4 %, respectively, for diagnosing smear-positive active PTB in elderly patients, and 100.0 %, 96.9 %, 76.5 %, 100.0 %, 3.1 % and 0.0 %, respectively, for non-elderly patients. HRCT can assist in the early diagnosis of the most infectious active PTB, thereby preventing transmission and minimizing unnecessary immediate respiratory isolation. (orig.)

    Abarca Araya, Steven

    2013-05-01

    Full Text Available Resumen: El presente ensayo surgió de una revisión bibliográfica que permitió conocer los alcances y las limitaciones de utilizar la Internet y las redes sociales como instrumento de mediación pedagógica. La Internet y las redes sociales han pasado a ocupar un espacio preponderante en la sociedad actual, utilizándose para promover bienes, servicios, entretenimiento y, en algunos casos, como instrumento de mediación pedagógica. Como resultado de la revisión realizada se pudo constatar que la utilización de las redes sociales como instrumento de mediación pedagógica ha permitido identificar sus bondades como mayor cobertura, asincronía en la mediación, aprendizaje colaborativo, aprendizaje autónomo, entre otros. Sin embargo, en contraste con las bondades que presenta, también tiene sus limitación es como la falta de pericia de docentes y estudiantes en el uso de la tecnología, el acceso, mayor inversión de tiempo en la mediación pedagógica, la renuencia de algunas personas al uso de la tecnología, la dificultad para controlar si es realmente el estudiante quien participa en las actividades pedagógicas, entre otros. Se concluye que todavía es muy apresurado hacer conjeturas acerca del futuro que le espera al uso de las redes sociales como instrumento de mediación pedagógica, pues algunos de estos alcances y limitaciones irán desapareciendo conforme vayamos adquiriendo mayor experiencia en su utilización, y su presencia sea cotidiana en nuestro sistema educativo, mientras que otros se seguirán manteniendo o, incluso, se pueden incrementar, por lo que debe analizarse su uso a la luz del contexto y la realidad de cada institución educativa.Abstract: This essay emerged from a literature review that yielded information on the scope and limitations of using the Internet and social media as a tool for teaching mediation.

    Full Text Available Abstract Background Pharmacological and genetic studies suggest the importance of the dopaminergic, serotonergic, and noradrenergic systems in the pathogenesis of Attention Deficit Hyperactivity Disorder (ADHD and Disruptive Behavior Disorder (DBD. We have, in a population-based sample, studied associations between dimensions of the ADHD/DBD phenotype and Monoamine Oxidase B (MAO-B activity in platelets and polymorphisms in two serotonergic genes: the Monoamine Oxidase A Variable Number of Tandem Repeats (MAO-A VNTR and the 5-Hydroxytryptamine Transporter gene-Linked Polymorphic Region (5-HTT LPR. Methods A population-based sample of twins, with an average age of 16 years, was assessed for ADHD/DBD with a clinical interview; Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL. Blood was drawn from 247 subjects and analyzed for platelet MAO-B activity and polymorphisms in the MAO-A and 5-HTT genes. Results We found an association in girls between low platelet MAO-B activity and symptoms of Oppositional Defiant Disorder (ODD. In girls, there was also an association between the heterozygote long/short 5-HTT LPR genotype and symptoms of conduct disorder. Furthermore the heterozygote 5-HTT LPR genotype in boys was found to be associated with symptoms of Conduct Disorder (CD. In boys, hemizygosity for the short MAO-A VNTR allele was associated with disruptive behavior. Conclusion Our study suggests that the serotonin system, in addition to the dopamine system, should be further investigated when studying genetic influences on the development of Disruptive Behavior Disorders.

Para obtener la información se aplicó el instrumento, diseñado por Bonilla y De Reales en al año 2006, conformado por 53 ítems y cuatro dimensiones, la cual cuenta con validez facial, de contenido y confiabilidad a 485 pacientes que cumplían los criterios de inclusión. Al instrumento se le realizó la validez de constructo por medio del análisis factorial de tipo exploratorio para determinar la correlación entre las variables y las cuatro dimensiones, por el método de extracción de componentes principales y rotación varimax con Kaiser. La consistencia interna del instrumento se realizó con los resultados que arrojó el análisis factorial (24 ítems y 4 dimensiones, a través del coeficiente alfa de Cronbach. Los resultados del estudio mostraron que la validez de constructo realizada al instrumento permitió reducir el número de ítems de 53 a 24 a través del análisis factorial, sin afectar las 4 dimensiones del instrumento; el índice de consistencia interna por medio del método del alfa de Cronbach fue de 0,60, lo cual se considera adecuado. Con la exclusión de los 29 ítems se generó una nueva versión del instrumento, que agrupa los 24 ítems en cuatro factores que explican el 45% de la varianza, lo que demostró que las variables se correlacionaban con lo que se pretendía medir, permitiendo sustentar teóricamente el constructo, haciéndolo más práctico en su aplicabilidad para los profesionales de enfermería en diferentes escenarios de cuidado. Esto demuestra que el instrumento es válido y confiable, y se puede aplicar en futuros estudios acerca de la adherencia, a fin de obtener una mejor

    2011-04-01

    Full Text Available A literatura mostra a importância da identificação precoce de sinais de atraso no desenvolvimento infantil e a dificuldade na escolha de instrumentos de avaliação. Os objetivos foram comparar o Denver II e a EDC com uma escala de referência (EEDP quanto à identificação de crianças com atraso de desenvolvimento, verificar diferença nos resultados considerando gênero dos participantes e averiguar a convergência dos resultados das escalas. Participaram 24 bebês de cinco a onze meses, de ambos os sexos, frequentadores de creches municipais. Os instrumentos foram aplicados individualmente e em sequência pré-definida. A análise estatística revelou que a escala EDC e o Denver II não podem ser considerados semelhantes à escala EEDP. Quanto ao gênero, não houve diferença significativa. Não houve convergência de itens falhos segundo as áreas. Assim, é importante ter cautela na escolha de instrumentos para triagem e obter informações de diferentes fontes sobre o desenvolvimento da criança.

    Full Text Available En este artículo nos centraremos en la evaluación neuropsicológica como proceso consistente en la utilización de diversas técnicas clínicas, psicométricas o neurológicas para conocer las peculiaridades del procesamiento en población normal y en personas que presentan algún trastorno, lesión o disfunción en el sistema nervioso. Analizaremos inicialmente qué se entiende por evaluación neuropsicológica, los ámbitos que toda evaluación neuropsicológica debe abarcar y que nos va a permitir obtener un perfil neuropsicológico comprehensivo. En coherencia con los ámbitos de exploración, analizamos los instrumentos que deben ser utilizados. Estos instrumentos pueden ser divididos en dos clases: instrumentos que, no habiéndose creado con una finalidad neuropsicológica, son utilizados en este campo con la intención de conocer el sustrato neurológico subyacente, y baterías de evaluación neuropsicológica propiamente dichas, tomando como referencia de ellas, la batería Luria-DNA.

Se sugiere que estudios futuros sean conducidos con base en el instrumento desarrollado, teniendo en cuenta contribuir para su refinamiento.This study is aimed at both describing the steps of construction of a qualitative instrument to investigate the emotional regulation strategies of Brazilian students, and reporting preliminary results. The sample was composed of 54 third and fourth grade basic education students of a public school in Campinas. The instrument consists of a 24 interview questions grouped into four emotions: sadness, anger, fear and happiness. It also includes eight boards with pictures of children expressing each of the emotions investigated. Students' answers to interview questions were studied through content analysis. A system of categories was developed for each question and the reliability of the coding procedures was evaluated by two independent raters. The percentage of agreement between them was acceptable. The results showed that engagement in pleasant activities was the most frequent strategy to deal with sadness, anger, fear and to keep happiness. Future studies employing this instrument should be carried out to better refine it.

    Full Text Available Abstract Background Many Australian children are insufficiently active to accrue health benefits and physical activity (PA levels are consistently lower among youth of low socio-economic position. PA levels decline dramatically during adolescence and evidence suggests that competency in a range of fundamental movement skills (FMS may serve as a protective factor against this trend. Methods/design The Supporting Children’s Outcomes Using Rewards Exercise and Skills (SCORES intervention is a multi-component PA and FMS intervention for primary schools in low-income communities, which will be evaluated using a group randomized controlled trial. The socio-ecological model provided a framework for the 12-month intervention, which includes the following components: teacher professional learning, student leadership workshops (including leadership accreditation and rewards, e.g., stickers, water bottles, PA policy review, PA equipment packs, parental engagement via newsletters, FMS homework and a parent evening, and community partnerships with local sporting organizations. Outcomes will be assessed at baseline, 6- and 12-months. The primary outcomes are PA (accelerometers, FMS (Test of Gross Motor Development II and cardiorespiratory fitness (multi-stage fitness test. Secondary outcomes include body mass index [using weight (kg/height (m2], perceived competence, physical self-esteem, and resilience. Individual and environmental mediators of behavior change (e.g. social support and enjoyment will also be assessed. The System for Observing Fitness Instruction Time will be used to assess the impact of the intervention on PA within physical education lessons. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA behavior change will be explored. Discussion SCORES is an innovative primary school-based PA and FMS intervention designed to support students attending schools in low-income communities to be more skilled

    Feldman, Michal; Meir, Reshef; Tennenholtz, Moshe

    2011-01-01

    We introduce a measure for the level of stability against coalitional deviations, called \\emph{stability scores}, which generalizes widely used notions of stability in non-cooperative games. We use the proposed measure to compare various Nash equilibria in congestion games, and to quantify the effect of game parameters on coalitional stability. For our main results, we apply stability scores to analyze and compare the Generalized Second Price (GSP) and Vickrey-Clarke-Groves (VCG) ad auctions....

    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.

  4. Correlation of signal intensity ratio on orbital MRI-TIRM and clinical activity score as a possible predictor of therapy response in Graves' orbitopathy - a pilot study at 1.5 T

    This study seeks to describe the predictive value of the signal intensity ratio (SIR) in magnetic resonance imaging-turbo inversion recovery magnitude (MRI-TIRM) in patients with Graves' orbitopathy (GO) with regard to predictability of therapy response. Included in this prospective pilot study were 36 consecutive patients with GO and 25 control subjects. Patients were clinically assessed according to the European Group on Graves' Orbitopathy recommendations with active GO defined by a clinical activity score (CAS) ≥ 3. On magnetic resonance (MR) imaging, muscle inflammation was measured with a region of interest set within the brightest extra-ocular muscle both on coronal turbo inversion recovery magnitude (TIRM) and on fat suppressed gadolinium-enhanced T1-weighted sequences. To calculate the SIR, the measured signal intensity was set in proportion to that of the ipsilateral temporalis muscle. Signal intensity ratio in coronal T2-weighted TIRM sequences in either group ranged from 1.22 to 4.92 (mean 2.04) in patients with GO and from 1.18 to 2.4 (mean 1.63) in controls without GO. The observed differences were significant on the TIRM sequences (right eye p = 0.023; left eye p = 0.022), whereas, no significant differences could be detected on the T1-weighted sequences (right eye p = 0.396; left eye p = 0.498). A cut off value of SIR > 2.5 for a CAS ≥ 4 to discriminate active from inactive patients was statistically calculated. T2 relaxation time is a reliable tool in detecting active GO. The difference in T2-SIR versus T1-SIR is helpful to distinguish inflammatory oedema of the extra ocular muscles from intra-orbital congestion due to reduced venous outflow. (orig.)

    Full Text Available Juridical instruments of pollution control are important components of the public politics related to natural resources and public health. In certain conditions, those instruments can be used to assure the public politics mentioned. The Brazilian juridical system hsa those instruments available to confront the possibility or the occurrence of the pollution for pesticides. Initial analysis of basic notions and terminology involved justify themselves because of the importance of the research activity and its evaluation. Those are used so much in documents, as in another bibliographical source, that it can be understood in many ways. It includes relationship of dates, facts and geopolitics situation concerning about the theme, and it comments, besides the implication with the social reaction to that pollution type. The new interpretations of the parameters of application has to be proposed and defended by the juridical responsability and the pesticide's registration concerning right. Basic references taken to sustainable development approach and the precautionary approach, both inserted in the Brazilian positive juridical system as it bases. It is still recognized in the Brazilian context the lack of control instruments for pesticides pollution that they did not include in the repressive group or control bureaucratic through the licensing. It was verified that the financial mechanismsmotivated the pesticides' employment, as well as rural credit. = Importantes componentes das políticas públicas relacionadas aos recursos naturais e à saúde pública, os instrumentos jurídicos de controle de poluição, em determinadas condições, podem ser utilizados para assegurar a efetivação dessas políticas.

  7. Ligand Identification Scoring Algorithm (LISA)

    Zheng, Zheng; Merz, Kenneth M.

    2011-01-01

    A central problem in de novo drug design is determining the binding affinity of a ligand with a receptor. A new scoring algorithm is presented that estimates the binding affinity of a protein-ligand complex given a three-dimensional structure. The method, LISA (Ligand Identification Scoring Algorithm), uses an empirical scoring function to describe the binding free energy. Interaction terms have been designed to account for van der Waals (VDW) contacts, hydrogen bonding, desolvation effects and metal chelation to model the dissociation equilibrium constants using a linear model. Atom types have been introduced to differentiate the parameters for VDW, H-bonding interactions and metal chelation between different atom pairs. A training set of 492 protein-ligand complexes was selected for the fitting process. Different test sets have been examined to evaluate its ability to predict experimentally measured binding affinities. By comparing with other well known scoring functions, the results show that LISA has advantages over many existing scoring functions in simulating protein-ligand binding affinity, especially metalloprotein-ligand binding affinity. Artificial Neural Network (ANN) was also used in order to demonstrate that the energy terms in LISA are well designed and do not require extra cross terms. PMID:21561101

    2013-06-01

    Full Text Available OBJETIVO: Analisar instrumento de medição da adesão ao tratamento da hipertensão por meio da "Teoria da Resposta ao Item". MÉTODOS: Estudo analítico com 406 hipertensos com complicações associadas, atendidos na atenção básica em Fortaleza, CE, 2011, pela "Teoria da Resposta ao Item". As etapas de execução foram: teste de dimensionalidade, calibração dos itens; tratamento dos dados e construção da escala, analisadas com base no modelo de resposta gradual. Estudo da dimensionalidade do instrumento foi feito pela análise da matriz de correlação policórica e análise fatorial de informação completa. Utilizou-se o software Multilog para calibração dos itens e estimação dos escores. RESULTADOS: Os itens referentes ao tratamento medicamentoso foram os mais diretamente relacionados à adesão, enquanto aqueles referentes ao tratamento não medicamentoso precisam ser reformulados, pois possuíram menor quantidade de informação psicométrica e baixa discriminação. A independência dos itens, o reduzido número de níveis da escala e as baixas variâncias explicadas no ajuste dos modelos mostraram as principais fragilidades do instrumento analisado. A "Teoria da Resposta ao Item" mostrou-se relevante para análise, pois avaliou o respondente quanto à adesão ao tratamento da hipertensão, ao nível de dificuldade dos itens e à sua capacidade de discriminação entre indivíduos com diferentes níveis de adesão, o que gerou maior quantidade de informação. CONCLUSÕES: O instrumento analisado é limitado para medir a adesão ao tratamento da hipertensão, mediante análise pela "Teoria da Resposta ao Item", e necessita de ajustes. A adequada formulação dos itens é importante para medir precisamente o traço latente desejado.

Como resultado de la revisión realizada se pudo constatar que la utilización de las redes sociales como instrumento de mediación pedagógica ha permitido identificar sus bondades como mayor cobertura, asincronía en la mediación, aprendizaje colaborativo, aprendizaje autónomo, entre otros. Sin embargo, en contraste con las bondades que presenta, también tiene sus limitación es como la falta de pericia de docentes y estudiantes en el uso de la tecnología, el acceso, mayor inversión de tiempo en la mediación pedagógica, la renuencia de algunas personas al uso de la tecnología, la dificultad para controlar si es realmente el estudiante quien participa en las actividades pedagógicas, entre otros. Se concluye que todavía es muy apresurado hacer conjeturas acerca del futuro que le espera al uso de las redes sociales como instrumento de mediación pedagógica, pues algunos de estos alcances y limitaciones irán desapareciendo conforme vayamos adquiriendo mayor experiencia en su utilización, y su presencia sea cotidiana en nuestro sistema educativo, mientras que otros se seguirán manteniendo o, incluso, se pueden incrementar, por lo que debe analizarse su uso a la luz del contexto y la realidad de cada institución educativa.

  2. Sobre o uso da sublimação como instrumento para uma "metapsicologia da arte"

    2014-01-01

    Full Text Available Neste artigo investigaremos a noção freudiana de sublimação e seu uso como mecanismo explicativo para os processos artísticos. Notaremos que, pela sua construção, aliás, confusa e carente de formalização conceitual, é impossível separar a sublimação do campo clínico no qual nasce e no qual encontra sua potência, como descrição de uma vicissitude e de uma possibilidade de lidar com a pulsão. Dessa forma, proporemos uma delimitação de qualquer "metapsicologia da arte" como instrumento clínico, antes que como instrumento de análise ou crítica da arte. Não obstante, notaremos a influência recíproca entre a psicanálise e a estética de seu tempo.

    2002-01-01

    Full Text Available Introduction Induction of labor represents initiation of uterine contractions before their spontaneous onset. The aim of the study was to establish the role of Bishop score in prediction of labor induction in routine clinical work. Material and methods The study was a prospective blind, observational one. All patients had a vaginal examination prior to induction, during which Bishop score was evaluated. The mode of induction was either intravenous infusion of oxytocin or endovaginal prostaglandins. The induction was considered successful if vaginal delivery took place within 24 hours from the onset of induction. Results There were 100 patients, and induction was successful in 74% and unsuccessful in 26%. Mean Bishop score in group A was 5.65 (SD 1.40, 95% CI 5.27 - 6.03, and in group B 4.15 (SD 1.04, 95% CI 3.66 - 4.63 (p < 0.01. Statistical analysis of the area under the ROC curve showed that Bishop score is a good and reliable predictor of the outcome of labor induction (0.816, 95% CI od 0.710 - 0.896, with the best statistical performances at the cut-off value of 5 (sensitivity 65.5% specificity 95%, PPV 97.3%, NPV 50%. Conclusion In our study Bishop score proved to be a reliable and good method for prediction of the outcome of pregnancy if a single, experienced operator evaluates it, with best statistical performances at the cut-off value more than 5 (sensitivity 65.5%, specificity 95%, PPV 97.3%, NPV 50%. The next step would be introduction of more operators, of different skills and experience and subsequent further testing of the method in different conditions.

    Traumatic injuries frequently lead to infection, organ failure, and death. Health care providers rely on several injury scoring systems to quantify the extent of injury and to help predict clinical outcome. Physiological, anatomical, and clinical laboratory analytic scoring systems (Acute Physiology and Chronic Health Evaluation [APACHE], Injury Severity Score [ISS]) are utilized, with limited success, to predict outcome following injury. The recent development of techniques for measuring the expression level of all of a person’s genes simultaneously may make it possible to develop an injury scoring system based on the degree of gene activation. We hypothesized that a peripheral blood leukocyte gene expression score could predict outcome, including multiple organ failure, following severe blunt trauma. To test such a scoring system, we measured gene expression of peripheral blood leukocytes from patients within 12 h of traumatic injury. cRNA derived from whole blood leukocytes obtained within 12 h of injury provided gene expression data for the entire genome that were used to create a composite gene expression score for each patient. Total blood leukocytes were chosen because they are active during inflammation, which is reflective of poor outcome. The gene expression score combines the activation levels of all the genes into a single number which compares the patient’s gene expression to the average gene expression in uninjured volunteers. Expression profiles from healthy volunteers were averaged to create a reference gene expression profile which was used to compute a difference from reference (DFR) score for each patient. This score described the overall genomic response of patients within the first 12 h following severe blunt trauma. Regression models were used to compare the association of the DFR, APACHE, and ISS scores with outcome. We hypothesized that patients with a total gene response more different from uninjured volunteers would tend to have poorer

    2015-01-01

    Team performance is a ubiquitous area of inquiry in the social sciences, and it motivates the problem of team selection -- choosing the members of a team for maximum performance. Influential work of Hong and Page has argued that testing individuals in isolation and then assembling the highest-scoring ones into a team is not an effective method for team selection. For a broad class of performance measures, based on the expected maximum of random variables representing individual candidates, we...

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

    Jeffrey J. Steinert

    2007-05-01

    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.

    Full Text Available Durante los 30 últimos años, los mercados financieros han registrado un enorme desarrollo. La introducción de los derivados financieros tales como opciones y futuros sobre subyacentes (títulos, obligaciones, monedas extranjeras, etc han conducido a una nueva cualidad de la seguridad de los riesgos financieros. La idea básica de un derivado financiero es comprar un seguro que cubra los activos arriesgados en el mercado, es decir, encontrar participantes en el mercado que traten de compartir los riesgos y los beneficios de los desarrollos futuros en el mercado en el que están sometidos a la incertidumbre. Una valoración de estos instrumentos financieros está basada en una teoría estadísticomatemática muy avanzada, llamada “Cálculo estocástico aplicado al campo financieroactuarial”. El modelo básico asociado a los precios de los títulos (valores, está expresado mediante el movimiento Browniano y ecuaciones diferenciales estocásticas. La valoración de una opción call Europea por Black, Scholes y Merton en 1973, fue un descubrimiento respecto a la comprensión y valoración de los derivados financieros. Su enfoque ha llegado a ser la base empresarial para las matemáticas financiero-actuariales modernas que utilizan instrumentos tales como la “teoría de martingalas” y “control estocástico” para obtener soluciones adecuadas en lo relativo a la valoración de un amplio campo del creciente número de derivados.

  12. Post-docking virtual screening of diverse binding pockets: comparative study using DOCK, AMMOS, X-Score and FRED scoring functions.

    Pencheva, Tania; Soumana, Oumarou Samna; Pajeva, Ilza; Miteva, Maria A

    2010-06-01

    Most of the benchmark studies on docking-scoring methods reported in the last decade conclude that no single scoring function performs well across different protein targets. In this study a comparison of thirteen commonly used force field and empirical scoring functions as implemented in DOCK, AMMOS, X-Score and FRED is carried out on five proteins with diverse binding pockets. The performance is analyzed in relation to the physicochemical properties of the binding sites. The solvation effects are considered via the Generalized Born/Surface Area (GBSA) solvation method for one of the assessed scoring functions. We examined the ability of these scoring functions to discriminate between active and inactive compounds over receptor-based focused libraries. Our results demonstrated that the employed here empirical scoring functions were more appropriate for the pocket of predominant hydrophobic nature while the force field scoring functions performed better on the mixed or polar pockets.

    Full Text Available AIM: To compare Greek stroke score with available previous two stroke scores for the diagnosis of cerebral ischemia and hemorrhage in acute stroke patients, and validate the Greek stroke score. SETTING: A tertiary hospital in India. MATERIALS AND METHODS: In a prospective study acute stroke patients were evaluated with Greek stroke score, Allen score and Siriraj stroke score. Comparability (Kappa Statistics and validity (sensitivity, specificity, negative predictive value and positive predictive value of the Greek stroke score and previous scores were tested. RESULT: Out of the 91 patients enrolled in the study, 47 patients had cerebral infarction and 44 patients had hemorrhage by CT scan. Allen score was uncertain / equivocal in 39 patients, Siriraj Stroke score in 22 and Greek stroke score in 47 patients. Sensitivity, Specificity, positive predictive value, negative predictive value for Allen score were 0.5(95% CI:0.34,0.58, 0.94(95% CI:0.86,0.98, 0.81(95% CI:0.56,0.95, 0.78(95% CI: 0.71,0.81 for Siriraj score were 0.75(95% CI: 0.63,0.84, 0.81(95% CI: 0.71,0.89, 0.77(95% CI: 0.65,0.86, 0.78(95% CI 0.69,0.86 and for Greek Score were 0.42(95% CI: 0.23,0.53, 0.93(95% CI: 0.87,0.98, 0.71(95% CI:0.39,0.91, 0.81(95% CI:0.75,0.85 respectively. Greek stroke score was compared with previous scores using kappa statistics which revealed substantial strength of agreement between the Allen Score for certain results. CONCLUSION: The overall comparability of Greek stroke score and Allen score was better as compared to Greek stroke score and Siriraj stroke score. Greek Stroke score was more specific in diagnosing hemorrhage as compared to Siriraj score. However, all these stroke scores lack accuracy hence could not be applied safely to guide the physician in management of stroke.

    Full Text Available Highly active antiretroviral therapy (HAART has been associated with dysglycaemia. However, there is scarce data on the risk of developing diabetes mellitus (DM in HIV/AIDS patients in Africa.Primarily to quantify and compare the risk of having diabetes mellitus in HIV/AIDS patients on HAART and HAART-naïve patients in Limbe, Cameroon; and secondarily to determine if there is an association between HAART and increased DM risk.A cross-sectional study was conducted at the Limbe Regional Hospital HIV treatment center between April and June 2013, involving 200 HIV/AIDS patients (100 on first-line HAART regimens for at least 12 months matched by age and gender to 100 HAART-naïve patients. The Diabetes Risk Score (DRS was calculated using a clinically validated model based on routinely recorded primary care parameters. A DRS ≥ 7% was considered as indicative of an increased risk of developing DM.The median DRS was significantly higher in patients on HAART (2.30% than in HAART-naïve patients (1.62%, p = 0.002. The prevalence of the increased DM risk (DRS ≥ 7% was significantly higher in patients on HAART, 31% (95% CI: 22.13-41.03 than in HAART-naïve patients, 17% (95% CI: 10.23-25.82, p = 0.020. HAART was significantly associated with an increased DM risk, the odds ratio of the HAART group compared to the HAART-naïve group was 2.19 (95% CI: 1.12-4.30, p = 0.020. However, no association was found after adjusting for BMI-defined overweight, hypertension, age, sex, family history of DM and smoking (Odds ratio = 1.22, 95% CI: 0.42-3.59, p = 0.708. Higher BMI and hypertension accounted for the increased risk of DM in patients on HAART. Also, more than 82% of the participants were receiving or had ever used Zidovudine based HAART regimens.HIV/AIDS patients on HAART could be at a greater risk of having DM than HAART-naïve patients as a result of the effect of HAART on risk factors of DM such as BMI and blood pressure.

    questionnaires were presented in part I; and, here in part II, one functional questionnaire and two sets of diagnostic criteria. Indices consist of organized forms for assigning scores to signs and symptoms thus obtaining severity degrees. Questionnaires are better employed for epidemiological purposes. Functional questionnaires are better used to assess impact of TMD on daily life activities. There are few specific sets of systematised diagnostic criteria available for diagnosing TMD. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD has been partially translated into Portuguese and had its accuracy and most psychometric properties validated, hence seems the best choice for assessing TMD.

    Introduction: The Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations instrument was developed to implement the conceptual framework of the Chronic Care Model in the Spanish national health system. It has been used to assess readiness to tackle chronicity in health care organisations. In this study, we use self-assessments at macro-, meso- and micro-management levels to (a) describe the two-year experience with the Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations tool in Spain and (b) assess the validity and reliability of this instrument. Methods: The results from 55 organisational self-assessments were included and described. In addition to that, the internal consistency, reliability and construct validity of Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations were examined using Cronbach's alpha, the Spearman–Brown coefficient and factorial analysis. Results: The obtained scores reflect opportunities for improvement in all dimensions of the instrument. Cronbach's alpha ranged between 0.90 and 0.95 and the Spearman–Brown coefficient ranged between 0.77 and 0.94. All 27 components converged in a second-order factorial solution that explained 53.8% of the total variance, with factorial saturations for the components of between 0.57 and 0.94. Conclusions: Instrumento de Evaluación de Modelos de Atención ante la Cronicidad/Assessment of Readiness for Chronicity in Health Care Organisations is an instrument that allows health care organisations to perform self-assessments regarding their readiness to tackle chronicity and to identify areas for improvement in chronic care.

    Assessment of adolescents' dietary habits is challenging. Reliable instruments to monitor dietary trends are required to promote healthier behaviours in this group. The purpose of this cross-sectional study was to assess adolescents' adherence to Norwegian dietary recommendations with a diet score and to report results from, and test-retest reliability of, the score. The diet score involved seven food groups and one physical activity indicator, and was applied to answers from a semi-quantitative food frequency questionnaire (FFQ) administered twice. Reproducibility of the score was assessed with Cohen's Kappa (κ statistics) at an interval of three months. The setting was eight lower-secondary schools in Hordaland County, Norway, and subjects were adolescents (n = 472) aged 14-15 years and their caregivers. Results showed that the proportion of adolescents consistently classified by the diet score was 87.6% (κ = 0.465). For food groups, proportions ranged from 74.0% to 91.6% (κ = 0.249 to κ = 0.573). Less than 40% of the participants were found to adhere to recommendations for frequencies of eating fruits, vegetables, added sugar, and fish. Highest compliance to recommendations was seen for choosing water as beverage and limit the intake of red meat. The score was associated with parental socioeconomic status. The diet score was found to be reproducible at an acceptable level. Health promoting work targeting adolescents should emphasize to increase the intake of recommended foods to approach nutritional guidelines. PMID:27483312

    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, tractio...

    Patients’ reports of their experience with illness are a key health outcome, but scores that measure these reports can be difficult to interpret. Skindex-29 measures skin-related quality of life reliably and validly. In this issue, Prinsen and colleagues compare patients’ responses to “anchor” questions with their Skindex scores to derive clinically meaningful scores for the subscales of Skindex-29. The cutoff scores identify patients whose skin diseases severely affect their quality of life....

    Full Text Available O trabalho analisa o impacto do uso de derivativos e a direção e magnitude do prêmio de cobertura relacionado a cada tipo de instrumento derivativo no valor da firma para uma amostra de empresas brasileiras não financeiras de capital aberto no período de 2004 a 2007. Os resultados indicam que a utilização de derivativos está relacionada a um impacto positivo e significativo sobre o valor de mercado das empresas. As evidências mostram que o uso de derivativos está associado a um “prêmio de cobertura” (hedging premium. Dessa maneira, é possível afirmar que as firmas que fazem uso da gestão de risco com derivativos têm um valor de mercado superior, no mercado brasileiro, quando comparadas a firmas que não utilizam esses instrumentos financeiros (hedging premium. Os resultados também indicam que, quando a análise se concentra no tipo de instrumento utilizado, a gestão de risco com tipos distintos de derivativos gera impacto de magnitude heterogênea no valor da firma. Contratos de swap e futuro/termo apresentam um impacto positivo e estatisticamente significante. Já para as opções, o impacto, embora positivo, não é estatisticamente significativo. Portanto, os resultados obtidos não só confirmam as expectativas de que a utilização de instrumentos derivativos exerce um impacto positivo e estatisticamente significativo sobre o valor da firma, mas também mostram que existe uma diferença relevante no efeito associado a derivativos distintos. Em conjunto, os resultados corroboram o fato de que investidores estão dispostos a pagar um maior valor por firmas que fazem gestão ativa de risco financeiro em ambientes mais voláteis como o Brasil, e essa disposição varia de acordo com o instrumento utilizado e com a eventual combinação de derivativos financeiros. Em pesquisa futura, uma análise das causas do impacto heterogêneo dos distintos instrumentos derivativos deve ser realizada para um melhor entendimento dos

  7. "Score Choice": A Tempest in a Teapot?

    Hoover, Eric

    2009-01-01

    A new option that allows students to choose which of their test scores to send to colleges has generated renewed criticism of the College Board. College Board officials tout the option, called Score Choice, as a way to ease test taker anxiety. Some prominent admissions officials have publicly described Score Choice as a sales tactic that will…

  8. Propuesta para el desarrollo de instrumentos de autoevaluación para programas educativos a distancia

    Full Text Available El presente trabajo expone la etapa inicial de un proyecto conjunto entre la Universidad Juárez Autónoma de Tabasco (UJAT y la Universidad Autónoma de Chiapas (UNACH, México; se trata de una estrategia diseñada para elaborar mecanismos que permitan a los programas virtuales autoevaluarse. La propuesta surge como resultado de la aplicación de un modelo de autoevaluación de programas a distancia diseñado por la Asociación Nacional de Universidades e Instituciones de Educación Superior (ANUIES y tomado como referencia para instrumentar en la UJAT, un ejercicio de autodiagnóstico durante el periodo 2008-2009. Los resultados mostraron la necesidad de pensar en mecanismos de evaluación situados en el contexto regional. La propuesta descansa, principalmente, en la revisión documental y en el panel de expertos elegidos mediante el método Delphi y Método combinado TZ. La estrategia metodológica consta de cuatro etapas: a revisión de modelos de evaluación; b la selección de expertos de dos universidades de los Estados de Tabasco y Chiapas que cuentan desde hace más de diez años con programas virtuales; c el diseño de instrumentos de auto diagnóstico y d la calificación de los instrumentos por los expertos. El reporte describe tres de las cuatro etapas del estudio. El promedio del índice de expertos en la autoevaluación fue similar en las dos universidades; se concluye, por lo tanto, que los expertos comparten un nivel de conocimiento afín, en especial en el diseño de materiales u objetos de aprendizaje, no así en indicadores de calidad estimados para la educación virtual.

  9. El comercio internacional un instrumento para alcanzar el desarrollo de Costa Rica

    Álvaro Martín Parada Gómez

    2011-12-01

    Full Text Available El comercio internacional es un instrumento para la consecución del económico en los países subdesarrollados.  En Costa Rica las ventajas del libre comercio están asociadas a la generación de exportaciones, así como a la mayor producción y generación de nuevas oportunidades de empleo en comparación con las fuentes tradicionales.  No obstante, persisten desventajas asociadas al tamaño del país, la presencia de imperfecciones de mercado, las fuertes distorsiones causadas por la intervención estatal por la excesiva regulación, entre otras causas.  El propósito es explicar las ventajas y desventajas que tienen las empresas y los sectores productivos para competir en el comercio internacional y sugerir lineamientos estratégicos que fortalezcan la posición de las empresas en el mercado internacional.  Las dos principales interrogantes que orientan este trabajo son: ¿cuáles obstáculos enfrentan las empresas de países en desarrollo como Costa Rica para posicionarse exitosamente en los mercados internacionales?, y ¿cuál estrategia podría seguir Costa Rica para competir adecuadamente en esos mercados? La principal conclusión es que los tratados de libre comercio son instrumentos para la consecución del desarrollo económico y, por tanto, no es adecuado poner todos los esfuerzos en ellos como única fuente de superación de las múltiples necesidades sociales y económicas que experimentan las economías en desarrollo. Con seguridad, se requerirá formular políticas adicionales en el campo de la infraestructura, tecnología, salud, educación, entre otros, para posicionar mejor al país en los mercados internacionales.
