Authors: Miloslavsky Molly , Galler Marjorie F. , Moawad Iman , Actis Janet , Cummings Brian M. , El Saleeby Chadi M.
Published: May 2017

BACKGROUND AND OBJECTIVES:

There are limited data guiding vancomycin dosing practices in the pediatric population to target the goal troughs recommended by national vancomycin guidelines. In this study, we sought to improve adherence to guideline trough targets through a quality improvement intervention.

METHODS:

A retrospective analysis was first conducted to assess baseline performance. A multidisciplinary team then developed and implemented a standardized dosing algorithm recommending 15 mg/kg per dose for mild and moderate infections (goal trough: 10–15 µg/mL) and 20 mg/kg per dose for severe infections (goal trough: 15–20 µg/mL), both delivered every 6 hours (maximum single dose: 750 mg). The impact of the intervention was evaluated prospectively using standard statistics and quality improvement methodology. The outcome measures included the percentage of patients with an initial therapeutic trough and the time to therapeutic trough.

RESULTS:

A total of 116 patients (49 preintervention, 67 postintervention) were included. Postintervention, there was a significant increase in the percentage of patients with an initial therapeutic trough (6.1% to 20.9%, P = .03) and in the percentage of patients with initial troughs between 10 and 20 µg/mL (8.2% to 40.3%, P < .001). The time to therapeutic trough decreased from 2.78 to 1.56 days (P = .001), with the process control chart showing improved control postintervention. Vancomycin-related toxicity was unchanged by the intervention (6.1% versus 4.5%; P = .70).

CONCLUSIONS:

Using quality improvement methodology with standardized higher initial vancomycin doses, we demonstrated improved adherence to national trough guidelines without noted safety detriment.

Published: May 2017

BACKGROUND AND OBJECTIVES:

Researchers often struggle with the gap between efficacy and effectiveness in clinical research. To bridge this gap, the Community Healthcare for Asthma Management and Prevention of Symptoms (CHAMPS) study adapted an efficacious, randomized controlled trial that resulted in evidence-based asthma interventions in community health centers.

METHODS:

Children (aged 5–12 years; N = 590) with moderate to severe asthma were enrolled from 3 intervention and 3 geographically/capacity-matched control sites in high-risk, low-income communities located in Arizona, Michigan, and Puerto Rico. The asthma intervention was tailored to the participant’s allergen sensitivity and exposure, and it comprised 4 visits over the course of 1 year. Study visits were documented and monitored prospectively via electronic data capture. Asthma symptoms and health care utilization were evaluated at baseline, and at 6 and 12 months.

RESULTS:

A total of 314 intervention children and 276 control children were enrolled in the study. Allergen sensitivity testing (96%) and home environmental assessments (89%) were performed on the majority of intervention children. Overall study activity completion (eg, intervention visits, clinical assessments) was 70%. Overall and individual site participant symptom days in the previous 4 weeks were significantly reduced compared with control findings (control, change of −2.28; intervention, change of −3.27; difference, −0.99; P < .001), and this result was consistent with changes found in the rigorous evidence-based interventions.

CONCLUSIONS:

Evidence-based interventions can be successfully adapted into primary care settings that serve impoverished, high-risk populations, reducing the morbidity of asthma in these high-need populations.

Published: May 2017

Objective: This study evaluated the effect of internal bleaching agents on the bond strength of glass fiber posts to root dentine.Methods: Seventy bovine teeth were divided into 7 experimental groups (n=10) according to the bleaching agent used: SpH – sodium perborate + 20% hydrogen peroxide; SpW – sodium perborate + distilled water; Cp37 – 37% carbamide peroxide; Cp16 – 16% carbamide peroxide; Cp10 – 10% carbamide peroxide; H – 35% hydrogen peroxide; C – no bleaching agent (control). After bleaching, posts were cemented with a self-adhesive resin cement (RelyX U100) and the roots were crosssectioned to obtain two discs from each third. The posts underwent micropush-out testing, and bond strength values (MPa) were analyzed using ANOVA in a split-plot arrangement and the Tukey test (p<0.05). Failure mode was evaluated under confocal microscopy.Results: There were no significant differences between the control and bleaching agent groups. Bond strength was greater in the cervical third of the 16% carbamide peroxide (Cp16) group than in the sodium perborate + 20% hydrogen peroxide (SpH) group. The cervical third had a higher bond strength than the apical third in the 10% carbamide peroxide (Cp10), 16% carbamide peroxide (Cp16) and sodium perborate + distilled water (SpW) groups, and no significant differences in the other groups. Adhesive cement-dentine failure was prevalent in all groups.Conclusion: The use of internal bleaching agents did not decrease the bond strength of glass fiber posts to root dentin.

Objective: to assess the effectiveness of adhesive system in reducing microleakage in Class II amalgam restorations.Methods: The teeth were divided randomly into 3 equal groups: Group I was the control experiment (Copal Vanish); Group II: single Bond Universal 3M-ESPE (with and without acid – 37%); and Group III: All Bond Universal – BISCO (with and without acid – 37%), after the amalgam was condensed. The root apices were then sealed with acrylic resin and stored for 24 hours in 100% humidity. After storage, the specimens were subjected to 500 cycles of thermocycling (5°C and 55°C). The teeth were isolated with cosmetic nail polish and were immersed in 0.5 basic fuchsin dye for 24 hours. The teeth then were sectioned with a diamond disc and observed under a stereomicroscope. Microleakage was assessed using a 0-3 scale of dye penetration. The data was analyzed using the Kruskal-Wallis test (p<0.05).Results: The microleakage scores revealed less leakage in the experimental groups than in the control group. The microleakage for the adhesives without acid conditioning was reduced, although no statistical significance was recorded (p<0.05).Conclusion: The immediate adhesive material acted effectively as a barrier for microleakage when it was applied without acid.

Objective: The purpose of this study was to evaluate, in vitro, the effectiveness of photodynamic therapy and sodium hypochlorite over root canal system infected with Enterococcus faecalis.Methods: The root canals of 45 single-rooted human extracted teeth were enlarged up to a file 60, autoclaved, inoculated with Enterococcus faecalis and incubated for 30 days. The samples were divided into five groups (G1 – n=5; G2-G5 – n=10) according to the protocol of decontamination: G1 (negative control) – no procedure was performed; G2 – distilled water; G3 –  hotodynamictherapy (PDT); G4 – 2.5% sodium hypochlorite (NaOCl); and G5 – 2.5% NaOCl+PDT. Scanning electron microscopy (SEM) were performed to evaluate the effectiveness of proposed treatments. The assessment was made by images of each third at 5000x magnification for the canal wall and 10000x for the exposed tubule area. The presence of bacteria was scored by position ranks from 1 to 45, where the higher the value, the cleanliness of the sample. Data were subjected to one-way ANOVA followed by post-hoc Tukey test (α=0.05).Results: Group 4 (2.5% NaOCl) and 5 (2.5% NaOCl + PDT) had the highest mean of position ranks for all thirds of the root canal in the canal wall, which was statistically different from groups 1, 2 and 3 (p<0.05). Group 3 (PDT), group 4 (2.5% NaOCl) and 5 (2.5% NaOCl+PDT) had the highest mean of position ranks in the exposed tubule area, which was statistically different from groups 1 and 2 (p<0.05).Conclusion: the association of 2.5% sodium hypochlorite + photodynamic therapy can be considered an effective protocol for the elimination of Enterococcus faecalis.

Dauricine is the major bioactive component isolated from the roots of Menispermum dauricum D.C., a bisbenzylisoquinoline alkaloid derivative, and has shown multiple pharmacological properties. In this work, a sensitive and selective ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was developed for determination of dauricine in rat plasma and its application to pharmacokinetic study of dauricine after intravenous and oral administration in rats. After addition of daurisoline as an internal standard (IS), protein precipitation by acetonitrile was used to prepare samples. Chromatographic separation was achieved on a UPLC BEH C18 column (2.1 mm × 50 mm, 1.7 μm) with 0.1% formic acid and acetonitrile as the mobile phase with gradient elution. An electrospray ionization source was applied and operated in positive ion mode; multiple reactions monitoring (MRM) mode was used for quantification. Calibration plots were linear throughout the range 2–600 ng mL−1 for dauricine in rat plasma. Relative standard deviation (RSD) of intra-day and inter-day precision was less than 13%. The accuracy of the method was between 95.8% and 105.9%. Matrix effect of dauricine in rat plasma ranged from 88.0% to 90.3%. Mean recoveries of dauricine in rat plasma ranged from 91.5% to 95.1%. The method was successfully applied to pharmacokinetic study of dauricine after intravenous and oral administration in rats. The bioavailability of dauricine was found to be 55.4% for the first time.

Proposed model for data security protection of cadastral information in Poland
Authors: Mika Monika
Published: May 2017

The paper presents a proposal for the data security model to protect the cadastral information
recorded in the databases of real estate in Poland. The model was developed for the implementa-
tion of multi-purpose cadastral tasks. The problem has been considered from the point of view
of the smooth functioning of the real estate market. Reliability of the real estate market is guar-
anteed by the full, accurate, easily available and current cadastral data. The latter is an important
piece of information about the area or land, essential for the implementation of most of the
real estate management processes. The publication indicates obligatory and optional sources of
cadastral information. The basis for the model of cadastral data security system is the compat-
ibility of the assumptions between the said model and the applicable law. The model contains
four types of disclosure status for cadastral data (confidential information, public information,
incomplete public information, non-confidential information requiring a license). The status
was adjusted to specified groups of users of the multipurpose cadastre. The aforementioned
groups are based on the entities, acting within the real estate market in Poland. The security
model presented herewith assumes a full transition to computer storage media, including the
descriptive information and spatial databases, contained in the multi-purpose cadastre, as well
as full interoperability of the data collected therein.

Published: May 2017

Lithofacies and paleogeographical characteristics of late Pleistocene-Holocene deposits are related to three sedimentary system tracts: Lowstand systems tract (LST) corresponds to the low regressive phase from 50 ka BP to 18 ka BP. The sedimentary accumulative space is situated from the boundary of weathering crust to the 100 m water depth. In Ba Lat rivermouth area, the lowstand systems tract is dominated by the alluvial silty sand facies group (arLST); Transgressive systems tract (TST) in Ba Lat rivermouth area constitutes a lithofacies section including three facies in upward direction as follows: (1) Transgressive alluvial silty - sand facies (atTST). (2) Transgressive estuary sandy - mud facies (amtTST). (3) Lagoonal maximum transgressive greenish clay facies (mtTST); Highstand systems tract (HST) in the downstream Red river delta area constitutes a deltaic plain structure consisting of three parts: High subaerial delta, low subaerial delta and subaqueous delta, which had been formed from 5 ka BP.

Authors: Rosa Eliezer Mazzetti , Silva Fernando Moreira da
Published: May 2017

A existência de hidrantes nas cidades é de suma importância no combate a incêndios, principalmente para garantir o abastecimento de água nos veículos-tanques utilizados pelo corpo de bombeiros. Nesse sentido, o presente estudo teve como objetivo analisar a distribuição desses equipamentos nas zonas administrativas sul, leste e oeste da cidade do Natal, Estado do Rio Grande do Norte (RN). Na primeira etapa, os equipamentos foram localizados através da ferramenta Street View do software Google Earth. As coordenadas geográficas foram obtidas através do modo de visualização Terra e depois conferidas in loco por meio de equipamento de navegação por satélite (GPS - Global Position System). Foram localizados e registrados um total de110 hidrantes nas três regiões. Destes registros, utilizando o software ArcGIS 9.3, foi gerado um arquivo vetorial de pontos e por meio das ortofotocartas na escala 1:2000, a localização geográfica de cada equipamento foi ajustada e convertida para projeção Universal Transversa de Mercator no Datum SAD69 e Zona 25 sul. Como método de análise de distribuição espacial, utilizou-se o estimador de densidade Kernel. O resultado observado foi uma distribuição geometricamente irregular de hidrantes nas três zonas administrativas analisadas, com algumas zonas com grande concentração e outras com ausência total de equipamentos. Assim, o uso desta ferramenta integrada ao Sistema de Informações Geográficas – SIG demonstrou ser útil para a localização espacial dos hidrantes e para nortear o planejamento para a instalação de novos equipamentos em zonas ainda não atendidas, uma vez que se trata de equipamentos essenciais para a segurança humana e proteção do patrimônio público e privado no combate a incêndios.

ECO2SEIA – LOW CARBON GREEN LABEL PRODUCTS: A GREEN MARKETING STUDY CASE
Authors: Paiva Teresa Maria Dias , Garcia Vânea
Published: May 2017

The importance of low carbon products has driven the Municipality of Seia, a small Portuguese town, to promote an eco-label for producers as a way to motivate this type of differentiation and as a means to distinguishing local products. Based on a literature review on sustainability, green marketing and environmental certification, this paper will address the way the community governance has designed its green strategy to launch this eco2SEIA eco-label – Low Carbon Products and how producers and consumers reacted and accepted this challenge. Demonstrating the importance of these actions on promoting the business and region sustainability, this paper also explains that, although the corporate social responsibility is a factor to be taken into account by companies, the investment in the green label as well as the impact on consumers did not meet the expectations. So, what went wrong is a question this paper proposes to answer.

En los últimos años los elevados costos en la molienda han focalizado la atención en el aumento de la eficiencia y en la disminución del consumo de medios de molienda. En esta línea han aparecido en el mercado una nueva serie de inhibidores para la corrosión y colectores para la flotación, bajo el nombre comercial de PETKOM. Estos reactivos son interesantes de estudiar porque disminuyen el consumo de acero y actúan como colectores selectivos,  entregando concentrados de mayor pureza en el caso de cobre. En este estudio se realizaron pruebas de laboratorio en paralelo, con y sin el uso de inhibidor, para determinar el consumo de acero. La densidad de pulpa usada en la prueba estándar fue de 70%, y con inhibidor de 76%, agregando una dosis de SKIK de 30 g/t en el molino. Los resultados mostraron un ahorro en el consumo de bolas de 1,9 % para para el mismo tiempo de molienda y gasto en energía; además el inhibidor permitió moler un porcentaje de mineral adicional de 9%. La eficiencia del SKIK como colector se puso a prueba en flotación, donde se comparó con el reactivo MATCOL (20 g/t), en dosis de 10, 20 y 30 g/t a diferentes pH. Este nuevo reactivo mostró un aumento en la recuperación de 1 a 2% en cobre, 9,2% en oro y 4,9% en plata.

ABSTRACT Objective A large number of psychosocial interventions in dementia are based on music activities and music therapy interventions. We aim at assessing the efficacy of music therapy in the neuropsychiatric symptoms of people with dementia. Methods This systematic review is according to the methodology suggested by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched for articles in PubMed, Web of Knowledge Cross Search, Cochrane Library, Scopus and Lilacs/Bireme databases published from 2005 to 2016. The search keywords included “early onset” and “late onset” combined with “dementia”, “Alzheimer”, “vascular dementia”, “mixed dementia”, “frontotemporal dementia”, “neuropsychiatric symptoms”, “behavioral disturbances”, “behavioral and psychological symptoms of dementia” and “music therapy”. The studies were categorized according to its efficacy on the decline of neuropsychiatric symptoms and improvement of cognitive function, quality of life and well-being. Results We selected 12 out of 257 papers. Music therapy interventions were applied individually or in group setting, using active or receptive technique. In general, studies indicated the efficacy of music therapy on the decline of depression, agitation and anxiety. There were heterogeneity of interventions, methodological design and instruments of evaluation among the studies. Conclusions Although there are reports of the efficacy of music therapy on the decline of neuropsychiatric symptoms of dementia, the area still needs randomized studies aimed at the solution of important methodological problems like the lack of standardized approaches.

Published: May 2017

Abstract The purpose of this study was to evaluate color stability of two dental ceramics cemented with two resin cements, assessing the color difference (ΔE00) by the measurement of L*, a*, b*, c* and h* of transmittance. The combination of two ceramic system (feldspathic and lithium disilicate) and two resin cements - color A3 (RelyX ARC and Variolink II) resulted in 4 groups (n=5). Ten disks-shaped specimens were fabricated for each ceramic system (10x1.5 mm), etched with hydrofluoric acid (10%) and silanized prior to cementation. The color analysis was performed 24 h after cementation of the samples and after 6 months of storage in relative humidity by means of spectrophotometry. The ΔE00 values were analyzed statistically by two-way ANOVA followed by the Tukey test (p<0.05). One-way ANOVA were calculated for the means of individual color coordinates (L*, a*, b*, c* and h*). Two-way ANOVA showed that only the ceramic factor was significant (p=0.003), but there was no difference for the cement factor (p=0.275) nor for the ceramic/cement interaction (p=0.161). The feldspathic ceramic showed the highest values of ΔE00. Variations in L*, a*, b*, c* and h* were more significant for feldspathic ceramic. In conclusion, storage alters similarly the optical properties of the resin cements and feldspathic porcelain was more susceptible to cement color change after aging.

Resumo Os novos materiais restauradores em desenvolvimento devem evitar danos aos tecidos dentários. Portanto, o objetivo deste estudo foi avaliar a biocompatibilidade de uma marca comercial de cimento de ionômero de vidro convencional (CIV) modificado com microfibras de celulose (CIV+MC) ou nanocristais de celulose (CIV+NC) através da implantação de três amostras em tecido subcutâneo na região dorsal de 15 ratos Rattus norvegicus albinus. Cada rato recebeu um exemplar de cada cimento, resultando nos seguintes grupos (n=15): Grupo CIV (controle, n=15), Grupo CIV+MC e Grupo CIV+NC. Nos intervalos de 7, 30 e 60 dias os animais foram sacrificados e os seguintes aspectos foram avaliados histologicamente: tipo de células inflamatórias, fibroblastos, vasos sanguíneos, macrófagos, células gigantes, tipo de reação inflamatória e espessura da cápsula (µm). Estes eventos foram quantitativamente classificados conforme os escores: (-) ausente, (+) suave, (++) moderado e (+++) intenso. Os resultados foram analisados estatisticamente pelo teste Kruskal-Wallis e pós-teste Mann-Whitney. Aos 7 dias, o Grupo CIV+NC demonstrou um nível mais elevado de reparação tecidual porque havia maior quantidade de fibroblastos (p=0,022) e uma menor quantidade de macrófagos (p=0,008) e células mononucleares (p=0,033). Neutrófilos e células gigantes estavam ausentes em todos os períodos experimentais. Aos 60 dias, o Grupo CIV+NC apresentou cápsula de tecido fibroso com espessura mais reduzida (26,72±2,87 µm) em comparação ao Grupo CIV+MC (41,21±3,98 µm (p=0,025). No geral, todos os materiais apresentaram satisfatória biocompatibilidade, no entanto, o cimento de ionômero de vidro modificado com nanocristais de celulose proveu reparação tecidual mais avançada comparativamente aos demais materiais avaliados.

Abstract The aim of this study was to evaluate the effect of different number of thermal cycles on the shear bond strength (SBS) of metallic orthodontic brackets bonded to feldspathic ceramic by a composite resin. Twenty-five ceramic cylinders were etched with 10% hydrofluoric acid for 60 s and received two layers of silane. Brackets were bonded to the cylinders using Transbond XT and assigned to 5 groups (n=5): Group 1 - Control group (without thermal cycling); Group 2 - 500 thermal cycles; Group 3 - 5,000 thermal cycles; Group 4 - 7,000 thermal cycles and Group 5 - 10,000 thermal cycles. Light-activation was carried out by Radii Plus LED. SBS testing was carried out after 24 h of storage in deionized water and thermal cycling (5/55 oC and 30 s dwell time). Five brackets were bonded to each cylinder, totalizing 25 brackets for each group. Data were submitted to one-way ANOVA and Tukey’s test (α=0.05). The Adhesive Remnant Index (ARI) was evaluated at 8× magnification. The SBS (MPa) of control group (9.3±0.8), 500 (9.0±0.7) and 5,000 (8.4±0.9) thermal cycles were significantly higher than those after 7,000 (6.8±0.6) and 10,000 (4.9±1.0) thermal cycles (p<0.05). The ARI showed a predominance of Scores 0 (adhesive failure) prevailed in all groups, as shown by the ARI, with increased scores 1 and 2 (mixed failures) for control group and 500 thermal cycles. In conclusion, thermal fatigue may compromise the bonding integration between metallic brackets and ceramic restorations. For in vitro testing, use of at least 7,000 cycles is advised to result in significant fatigue on the bonding interface.

Different social, biological and behavioral factors compose a network of causal factors for ECC. The aim was to evaluate the association between socioeconomic variables and caries at baseline, and the presence of Streptococcus mutans and Lactobacillus spp. microorganisms with the progression of caries lesions after two years of follow-up in a group of children. At baseline, 163 children (3-4 years old) living in the areas of 12 primary care services of the Hospital Group Conceição (GHC, Porto Alegre, RS, Brazil) were evaluated. After two years, 119 children were re-evaluated. Clinical examinations were conducted by calibrated examiners using the ICDAS criteria. A sociodemographic questionnaire was applied to the children’s parents and saliva samples were collected from the children for microbiological analysis. Descriptive statistics and multivariate Poisson regression analysis were performed in the statistical analysis. The factors associated with the caries progression were marital status of mothers (p=0.040), higher S. mutans counts (p=0.031) and the presence of cavitated lesions at baseline (p<0.001). The caries lesions progression in preschool children enrolled in primary health care was directly associated with marital status, presence of cavitated lesions at baseline and higher S. mutans counts at two-year follow-up.

Resumo O angioleiomioma é uma neoplasia benigna que, a partir da nova classificação da OMS (2013) para os tumores de tecidos moles, deixou de ser considerado um tumor de origem muscular lisa, passando a ser considerado um tumor de origem perivascular. Raramente os angioleiomiomas ocorrem na cavidade oral. A lesão é tratada cirurgicamente, com prognóstico considerado favorável. Este trabalho revisa os casos de angioleiomioma oral relatados na literatura nos últimos 5 anos e descreve esse tumor em um homem de 44 anos que apresentou um nódulo assintomático localizado em lábio superior, com evolução de 6 meses. As hipóteses diagnósticas foram de adenoma pleomórfico e adenoma canalicular. A lesão foi submetida à biópsia e análise histopatológica e imuno-histoquímica (S100, CD34, α-SMA, H-caldesmon e desmina) confirmaram o diagnóstico de angioleiomioma. Destacamos a imuno-histoquímica como um importante método auxiliar no diagnóstico diferencial do angioleiomioma com outras lesões e, principalmente, com o miopericitoma.

Resumo A trombose de veia porta é uma causa rara de abdome agudo vascular e está diretamente relacionada a trombofilias hereditárias ou adquiridas. O caso de um paciente de 60 anos, sexo masculino, com quadro clínico de isquemia mesentérica confirmada por exame de imagem é apresentado. Foi submetido a enterectomia e enteroanastomose e, após esplenoportografia que detectou trombose de veia porta, indicou-se tratamento medicamentoso com infusão contínua de ativador tecidual do plasminogênio recombinante (Alteplase) através de cateterismo seletivo da artéria mesentérica superior. Trata-se de um tratamento inovador. Obteve-se sucesso na recanalização do sistema porta. O paciente evoluiu com quadro de sepse abdominal, necessitando de assistência em terapia intensiva por 25 dias. Evoluiu bem e recebeu alta hospitalar com o uso de anticoagulante. O artigo apresenta uma breve revisão de literatura e discussão do caso clínico.

Resumo Contexto As amputações dos membros inferiores, sejam definidas como maiores ou menores, são um grave problema de saúde, com altos índices de morbimortalidade e de relevante impacto social. Diferentes características clínicas dos pacientes parecem estar relacionadas aos diferentes tipos de amputação realizados. Objetivos Analisar os fatores de risco presentes em pacientes submetidos a amputações de membros inferiores em hospital terciário. Métodos Estudo retrospectivo, transversal, envolvendo 109 pacientes submetidos a amputação de membro inferior em um período de 31 meses, através da análise de gênero e idade, 15 dados clínicos e cinco parâmetros laboratoriais presentes no momento da admissão. Os dados foram submetidos a estatística descritiva e comparativa através do teste t de Student não pareado (para variáveis numéricas), e dos testes de Mann-Whitney e exato de Fisher (para variáveis categóricas). Resultados Das 109 amputações realizadas, 59 foram maiores e 50 menores. A maioria dos pacientes era do gênero masculino (65%), e a média de idade foi de 65 anos (mín. 39, máx. 93). Dentre os fatores de risco observados, idade avançada, acidente vascular encefálico, isquemia, sepse e níveis baixos de hemoglobina e hematócrito estavam estatisticamente mais relacionados às amputações maiores (p < 0,05). Diabetes melito, neuropatia e pulsos distais palpáveis foram fatores mais associados às amputações menores. Conclusões Os níveis das amputações de membros inferiores estão relacionados a diferentes fatores de risco. Os quadros isquêmicos mais graves e de maior morbidade estiveram associados a amputações maiores, enquanto a neuropatia e perfusão preservada, mais relacionados às amputações menores.
On a new species of the genus Simlops (Araneae, Oonopidae) from Guyana, with notes on the bodanus group of species
Authors: Feitosa Níthomas M. , Bonaldo Alexandre B.
Published: May 2017

ABSTRACT A new species of Simlops Bonaldo, Ott & Ruiz, 2014, S. kartabo sp. nov., from Guyana is described. The new species belongs to the putatively basal bodanus species group, sharing with other species of the group a relatively simple embolar distal third. The presence of a filiform accessory process on the conductor, previously evidenced only for S. guatopo Brescovit, 2014 is also identified here for S. bodanus (Chickering, 1968), S. guyanensis Santos, 2014 and S. kartabo sp. nov. and may support the monophyly of the bodanus group.

ABSTRACT The universal goniometer (UG) is the most frequently used tool for measuring range of motion (ROM), with demonstrated reliability. Computerized photogrammetry (CP) is widely used for postural assessment, but its role in the measurement of ROM of hip flexion and abduction has not yet been fully explored. This study aimed to test inter- and intra-rater reliability for measuring ROM of hip flexion and abduction using UG and CP, as well as the reliability between the instruments. Our sample consisted of 40 healthy volunteers (aged from 18 to 28 years). Measurements of ROM were conducted by two independent raters, 15 minutes apart, using UG and CP to assess inter-rater reliability. The procedures were repeated one week later by the first rater (intra-rater reliability). Using UG, inter-rater reliability was excellent for flexion and abduction (ICC=0.92 and 0.91, respectively); using CP, it was rated as very good (ICC=0.77 and 0.80, respectively). Intra-rater reliability using UG was excellent for flexion and abduction (ICC=0.95 and 0.92), and very good using CP (ICC= 0.81 and 0.89). The correlation between the instruments was excellent for flexion and very good for abduction (r=0.92 and r=0.82). Future investigations should seek a more diversified sample and symptomatic patients. Inter- and intra-rater reliability is high when measuring range of motion of hip flexion and abduction using both UG and CP, and the correlation between instruments is excellent for flexion and very good for abduction, meaning that both are valid.

Exploratory and confirmatory factor analysis of the Roteiro de Avaliação da Consciência Fonológica, a phonological awareness test
Authors: SANTOS Acácia Aparecida Angeli dos , LIMA Thatiana Helena de
Published: May 2017

Abstract The objective of this study is to investigate the evidence of construct validity of a phonological awareness instrument. Exploratory factor analysis was carried out on data collected from 510 elementary and middle school students in 2nd and 6th grades attending two different public schools in the city of São Paulo, Brazil; most were males with mean age of 8.4 years. Confirmatory factor analysis was carried out on data collected from 427 students from other four Brazilian states in the same grades; most were females with mean age of 9.3 years. The instrument used was the Roteiro de Avaliação da Consciência Fonológica, a phonological awareness test. The exploratory factor analysis showed a three-factor solution. As for the confirmatory factor analysis, of the two models tested, the one that indicated better model fit indices was composed of three factors. The model found is adequate for the task carried out in this study. However, more studies should be carried out to further refine the instrument.

Published: May 2017

Resumo Este estudo foi realizado na abordagem contemporânea da Estratégia como Prática Social (EPS) com destaque para as práticas discursivas. Esta pesquisa teve como objetivo compreender como as práticas discursivas contribuíram no fazer estratégia de uma Instituição de Ensino Superior comunitária. A literatura apontou que pesquisas em EPS devem utilizar abordagem qualitativa, que foi a perspectiva adotada neste trabalho. Como método, optou-se pelo estudo de caso único e, para a coleta dos dados, foi utilizada a observação sistemática em cinco reuniões do planejamento estratégico, entrevista qualitativa com gestores dos cinco níveis hierárquicos da Universidade e, também, a análise documental. Para analisar os dados, foi utilizada a análise semiótica peirceana-Dias (2015). Dessa análise, verificou-se que contribuíram no fazer estratégia: o contexto histórico-social; a relação de poder entre os estrategistas das áreas acadêmica e meio, que está implícita nas práticas discursivas; as vozes dos praticantes que emergiram dos dados (vozes do líder, gestor e consultor externo); e o processo decisório que, na perspectiva da EPS, pode ter trazido limitações, uma vez que os cento e onze estrategistas não participaram de todas as etapas do planejamento, sobretudo os da área meio.

RESUMO Objetivou-se com este trabalho avaliar e comparar a viabilidade de um sistema agroflorestal a partir dos atributos físicos e hídricos do solo ao longo do tempo, conduzido na cidade de Curitibanos-SC com tratamentos: SAF-Erva Mate (SE), SAF-Frutífera (SF), SAF-Agrícola (SA), e uma área de Vegetação Nativa (VN) como testemunha. Foram abertas trincheiras aleatórias em cada tratamento para coleta das amostras de solo com estrutura preservada e alterada nas profundidades 0,0-0,05 m e 0,05-0,20 m no primeiro semestre de 2014 e 2015. As profundidades foram selecionadas de acordo com análises visuais da estrutura do solo. Foram determinados os atributos físicos e hídricos do solo e o balanço hídrico. A densidade do solo e a microporosidade proporcionaram um aumento significativo de seus atributos no decorrer do tempo. O sistema manteve-se dentro da capacidade de água disponível com balanço hídrico adequado ao desenvolvimento das culturas, o que o torna viável e sustentável.
