Comparison between the spastic paraplegia rating scale, Kurtzke scale, and Osame scale in the tropical spastic paraparesis/myelopathy associated with HTLV

INTRODUCTION:The objective of this study was to compare Osame's scale of motor incapacity and the expanded scale of the state of incapacity of Kurtzke with the spastic paraplegia rating scale for the clinical evaluation of patients with HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). METHODS: Patients with the diagnosis of infection by HTLV-I/HTLV-II and with the clinical suspicion of HAM/TSP were included in the study. RESULTS: There were 45 patients who were evaluated. When analyzing the results of the scales, the researchers found the following averages of 21.08 points for the spastic paraplegia rating scale, 4.35 points for Osame's scale, and 4.77 points for Kurtzke's scale. The relation between the scale of paraplegia with Osame's was very significant with p < 0.0001, and regarding Kurtzke's scale, there was a similar result of p < 0.0001. When comparing Osame's, Kurtze's, and the spastic paraplegia rating scale with the time of disease, the researchers found a significant result of p = 0.0004 for the scale of spastic paraplegia, p = 0.0018 for Osame's scale, and p < 0.0001 for Kurtzke's scale. CONCLUSION: The spastic paraplegia rating scale has a good relation with Osame's and Kurtzke's scales showing a p index that is very significant that indicates that, although the scale was not initially made to be applied to patients with HAM/TSP because of the infection by HLTV, it showed to be as efficient as Osame's and Kurtzke's scales in evaluating the patients' neurological conditions.

Importância do rating na padronização de debêntures

As debêntures padronizadas possibilitam aos investidores prescindir de complexas análises contratuais e cálculos sofisticados em mercados secundários. Este artigo analisa, com base em contratos de debêntures não padronizados, se, caso as diferenças contratuais fossem controladas estatisticamente, os ratings dessas debêntures seriam suficientes para captar os custos inerentes nas taxas de juros de suas emissões. Para tanto, analisamos uma amostra de 24 emissões de debêntures no período de 1999-2001, e verificamos se houve alguma diferença estatisticamente significativa (distribuição binomial) nas cláusulas contratuais entre as emissões com elevado rating e baixo rating. Concluímos que, para ratings elevados, a padronização afeta as taxas de juros como reflexo de seu rating. Contudo, para ratings baixos, a padronização não capta diferenças contratuais específicas, tais como repactuação programada e garantia.

Validade da versão em português da Clinical Dementia Rating

OBJETIVO: Analisar a validade da versão em português da Clinical Dementia Rating para classificar a função cognitiva de idosos. MÉTODOS: Utilizou-se o instrumento Mini-Mental State Examination para rastreamento de déficit cognitivo em coorte composta por 424 idosos. Foram selecionados todos que obtiveram escores <26 (108 idosos) e 48 idosos com escores >26. Os 156 idosos selecionados foram submetidos a uma avaliação clínica e testes neuropsicológicos para diagnóstico de casos de demência. Tanto os casos como os não-casos foram classificados segundo a versão em português da Clinical Dementia Rating em: normais, casos questionáveis e casos de demência leve, moderada ou grave. RESULTADOS: Entre os 156 avaliados, 122 eram não-casos, destes 62 (51%) foram classificados como normais (CDR=0) e questionáveis 60 (49%) (CDR=0,5). Entre os 34 casos de demência, 17 (50%) foram classificados como demência leve (CDR=1), 8 (23%) moderada (CDR=2) e 6 (18%) grave (CDR=3). Apenas três (9%) dos casos foram considerados questionáveis pelo Clinical Dementia Rating. Sua sensibilidade foi de 91,2% e a especificidade de 100%, com valor preditivo positivo de 100% e negativo de 97,6%. As pontuações no Mini-Mental State Examination declinaram significativamente conforme o grau de demência. CONCLUSÕES: O Clinical Dementia Rating mostrou ser instrumento válido para classificar o grau de demência entre idosos. Quase metade dos não-casos foram casos questionáveis pelo Clinical Dementia Rating e podem corresponder a casos de transtorno cognitivo leve, com maior risco de conversão em demência.

Content validity and reliability of test of gross motor development in Chilean children

ABSTRACT OBJECTIVE To validate a Spanish version of the Test of Gross Motor Development (TGMD-2) for the Chilean population. METHODS Descriptive, transversal, non-experimental validity and reliability study. Four translators, three experts and 92 Chilean children, from five to 10 years, students from a primary school in Santiago, Chile, have participated. The Committee of Experts has carried out translation, back-translation and revision processes to determine the translinguistic equivalence and content validity of the test, using the content validity index in 2013. In addition, a pilot implementation was achieved to determine test reliability in Spanish, by using the intraclass correlation coefficient and Bland-Altman method. We evaluated whether the results presented significant differences by replacing the bat with a racket, using T-test. RESULTS We obtained a content validity index higher than 0.80 for language clarity and relevance of the TGMD-2 for children. There were significant differences in the object control subtest when comparing the results with bat and racket. The intraclass correlation coefficient for reliability inter-rater, intra-rater and test-retest reliability was greater than 0.80 in all cases. CONCLUSIONS The TGMD-2 has appropriate content validity to be applied in the Chilean population. The reliability of this test is within the appropriate parameters and its use could be recommended in this population after the establishment of normative data, setting a further precedent for the validation in other Latin American countries.

Cross-cultural adaptation to Brazil of Medication Adherence Rating Scale for psychiatric patients

Objective The purpose of this research was to make a cross-cultural adaptation of the Medication Adherence Rating Scale (MARS) for psychiatric patients to the Brazilian context. Methods The procedure consisted of four phases: translation of the original scale, back-translation, review by an Expert Committee and Pre-test study with a patients’ sample. Results The Expert Committee corrected the items’ translation when necessary and modified the scale administration format and its instructions from self-report to face-to-face interview form in order to ensure easy understanding by the target population. During Pre-test, the instructions and most of the items were properly understood by patients, with the exception of three of them which had to be changed in order to ensure better understanding. The Pre-test sample was composed by 30 psychiatric patients, with severe and persistent disorders mainly single (46.7%), female (60.0%), with a mean age of 43.8 years old and an average of five years of education. Conclusion The Brazilian version of MARS scale is now adapted to the Brazilian Portuguese language and culture and is easily understood by the psychiatric target population. It is necessary to do further research to evaluate the scale psychometric qualities of validity and reliability in order to use it in Brazil.

Adaptação para a língua portuguesa e validação do Lunney Scoring Method for Rating Accuracy of Nursing Diagnoses

O Lunney Scoring Method for Rating Accuracy of Nursing Diagnoses (LSM) é uma escala de diferencial semântico que foi desenvolvida por Lunney para estimar a acurácia dos diagnósticos de enfermagem. O objetivo deste estudo foi adaptar o LSM para a língua portuguesa e avaliar as sua propriedades psicométricas. A escala original foi traduzida para o português, revertida para o inglês e as duas versões em inglês foram comparadas para ajustar a versão em português que passou a ser denominada Escala de Acurácia de Diagnóstico de Enfermagem de Lunney - EADE. Quatro enfermeiras foram orientadas sobre a EADE e a aplicaram em 159 diagnósticos formulados para 26 pacientes de três estudos primários com base nos registros de entrevista e exame físico de cada paciente. Os índices Kappa de Cohen mostraram ausência de concordância entre as avaliadoras, o que indica que o instrumento adaptado não tem confiabilidade satisfatória. Em virtude desse resultado, não foi realizada estimativa de validade.

Pain intensity among institutionalized elderly: a comparison between numerical scales and verbal descriptors

AbstractOBJECTIVECorrelating two unidimensional scales for measurement of self-reported pain intensity for elderly and identifying a preference for one of the scales.METHODA study conducted with 101 elderly people living in Nursing Home who reported any pain and reached ( 13 the scores on the Mini-Mental State Examination. A Numeric Rating Scale - (NRS) of 11 points and a Verbal Descriptor Scale (VDS) of five points were compared in three evaluations: overall, at rest and during movement.RESULTSWomen were more representative (61.4%) and the average age was 77.0±9.1 years. NRS was completed by 94.8% of the elderly while VDS by 100%. The association between the mean scores of NRS with the categories of VDS was significant, indicating convergent validity and a similar metric between the scales.CONCLUSIONPain measurements among institutionalized elderly can be made by NRS and VDS; however, the preferred scale for the elderly was the VDS, regardless of gender.

Nietzsche and Neo-Kantian historiography: points of contact

In the German academies of Nietzsche's period of writing, the Kantian tradition was largely displaced in favor of two independent schools that have since been labeled "Neo-Kantianism." This paper presents four key theses about philosophy of history from four Neo-Kantian thinkers, how they follow from their adaptation of the Kantian tradition, and how Nietzsche critically engaged the very same issues in the formation of his own historical theory. Although there is little direct influence between orthodox Neo-Kantianism and Nietzsche, their comparison on these points will illuminate their unique adaptations of the Kantian tradition.

Use data from permanent sampling points in growth and yield modeling

This study was carried to evaluate the efficiency of the Bitterlich method in growth and yield modeling of the even-aged Eucalyptus stands. 25 plots were setup in Eucalyptus grandis cropped under a high bole system in the Central Western Region of Minas Gerais, Brazil. The sampling points were setup in the center of each plot. The data of four annual mesurements were colleted and used to adjust the three model types using the age, the site index and the basal area as independent variables. The growths models were fitted for volume and mass of trees. The efficiency of the Bitterlich method was confirmed for generating the data for growth and yield modeling.

Turbidimetry as an alternative method to determine the rating curve of suspended sediments

Understanding hydrosedimental behavior of a watershed is essential for properly managing and using its hydric resources. The objective of this study was to verify the feasibility of the alternative procedure for the indirect determination of the sediment key curve using a turbidimeter. The research was carried out on the São Francisco Falso River, which is situated in the west of the state of Paraná on the left bank of ITAIPU reservoir. The direct method was applied using a DH-48 sediment suspended sampler. The indirect method consisted of the use of a linigraph and a turbidimeter. Based on the results obtained, it was concluded that the indirect method using a turbidimeter showed to be fully feasible, since it gave a power function-type mathematical model equal of the direct method. Furthermore, the average suspended sediment discharge into the São Francisco Falso River during the 2006/2007 harvest was calculated at 7.26 metric t day-1.

Monotonic trend and change points in southern Brazil precipitation

Scientific evidence on climate changes at global level has gained increasing interest in the scientific community in general. The impacts of climate change as well as anthropogenic actions may cause errors in hydro-agricultural projects existent in the watershed under study. This study aimed to identify the presence or absence of trend in total annual precipitation series of the watershed of the Mirim Lagoon, state of Rio Grande do Sul-RS / Brazil / Uruguay (Brazilian side) as well as to detect the period in which they occurred. For that, it was analyzed the precipitation data belonging to 14 weather stations. To detect the existence of monotonic trend and change points, it was used the nonparametric tests of Mann-Kendall and Mann-Whitney, the "t" test of Student for two samples of unpaired data (parametric), as well as the technique of progressive mean. The Weather Station 3152014 (Pelotas) presented changes in the trend in the series of annual precipitation in the period from 1953 to 2007. The methodologies that use subdivided series were more efficient in detecting change in trend when compared with the Mann-Kendall test, which uses the complete series (from 1921 to 2007).

Gross anatomical features of the oropharyngeal cavity of the ostrich (Struthio camelus)

Most descriptions of the ostrich oropharynx and oesophagus are superficial and supply little meaningful morphological data. The aim of this investigation is describe the ostrich oropharingeal cavity, in order to supply the deficiency of macroscopic data about this important animal. Five heads of 12 to 14-month-old ostriches of either sex were anatomically dissected to expose the oropharynx. The ostrich oropharynx was "bell-shaped" composed by the maxillary and mandibular ramphoteca. The roof and floor presented two distinct regions different in colour of the mucosa. The rostral region was pale pink contrasting to creamy-pink coloured caudal region. The median longitudinal ridge extended rostrally from the apex of the choana to the tip of the beak in the roof and it is clearly more prominent and rigid than the homolog in the floor that appeared thin and stretched rostrally, continuing caudally surrounding the tongue and the laryngeal mound eventually merging with the oesophageal mucosa. The floor was formed by the interramal region, tongue and laryngeal mound containing shield-shaped glottis. It can be concluded that the present study, in addition to confirming the basic features of the oropharynx previously described for the ostrich, clarified the contradictory information presented in the literature and also provided new, unreported morphological data, some of which may be important when studying nutrition and health in these birds.

Gross morphology of rhea oropharyngeal cavity

The rhea (Rhea americana americana) is an american bird belonging to Ratite's family. Studies related to its morphology are still scarce. This study aims to describe the macroscopic structures of the oropharyngeal cavity. Five heads (2 to 6 months old) formalin preserved were anatomically dissected to expose the oropharynx. The oropharynx of the rhea was "bell-shaped" composed by the maxillary and mandibular rhamphotheca. The roof and floor presented two distinct regions different in colour of the mucosa. The rostral region was pale pink contrasting to grey coloured caudal region. The median longitudinal ridge extended rostrally from the apex of the choana to the tip of the beak in the roof and it is clearly more prominent and rigid than the homolog in the floor that appeared thin and stretched merely along the rostral portion of the regio interramalis. The floor was formed by the interramal region, (regio interramalis) tongue and laryngeal mound containing glove-shaped glottis. This study confirmed the basic morphology of the oropharinx of the rhea. However, important morphological information not previously described is highlighted and contradictory information present in the literature is clarified.
