Abstract This study describes a set of recommendations to improve the precision of shear and punching shear capacity predictions for one-way slabs under concentrated loads, regardless of the governing failure mechanism, using the ABNT NBR 6118:2014 code provisions. For this purpose, a database of 143 test results was developed, including one-way slabs with different support conditions and loading layouts and that failed by different shear failure mechanisms: one-way shear, punching shear or a mixed mode. The key parameters influencing the load capacity and failure mechanism of these slabs were considered for the proposed recommendations: load position and slab width. Adjustments to the effective shear width definition and shear resisting control perimeter were described. Arching action for loads close to the support was also considered in both one-way shear and punching shear predictions. Considering the whole database and without separation by the failure mechanism, the ratio between tested and predicted resistances with the one-way shear expressions shows an average value of 1.22 and a coefficient of variation of 18.3%. The respective ratio between tested and predicted resistances with the punching shear expressions reached an average ratio of 1.23 with a coefficient of variation of 21.3%. Therefore, the proposed recommendations allow for reaching enhanced levels of precision in assessing the shear and punching shear capacity of one-way slabs under concentrated loads, regardless of the governing failure mechanism of the slabs.

Resumo Este estudo descreve um conjunto de recomendações para melhorar a precisão nas previsões de resistência ao cisalhamento e à punção de lajes unidirecionais sob cargas concentradas, independentemente do mecanismo governante na ruptura, utilizando as disposições da norma ABNT NBR 6118:2014. Para isso, foi organizado um banco de dados com 143 resultados de ensaios, incluindo lajes unidirecionais com diferentes condições de apoio e configurações de carregamento e que apresentaram diferentes mecanismos de ruptura por cisalhamento. Os principais parâmetros que influenciam a capacidade de carga e o mecanismo de ruptura dessas lajes foram considerados nas recomendações propostas. Ajustes para a definição da largura efetiva de cisalhamento e perímetro de controle resistente ao cisalhamento foram descritos. A ação de arqueamento para cargas próximas ao apoio também foi considerada nas previsões de resistência ao cisalhamento unidirecional e ao puncionamento. Considerando todo o banco de dados, a razão entre as resistências testadas e previstas com as expressões de cisalhamento unidirecional apresenta um valor médio de 1.22 e um coeficiente de variação de 18.3%. A respectiva relação entre as resistências testadas e previstas com as expressões de puncionamento atingiu uma relação média de 1.23 com um coeficiente de variação de 21.3%. Portanto, as recomendações propostas permitem alcançar maiores níveis de precisão na previsão da resistência ao cisalhamento e ao puncionamento de lajes unidirecionais sob cargas concentradas, independentemente do mecanismo de ruptura governante das lajes.

Resumen El presente estudio busca obtener evidencias de validez y confiabilidad de la Escala de Involucramiento Parental: Actividades de cuidado y socialización en una muestra de padres peruanos de niños y niñas preescolares. Para ello, se realizó una traducción y armonización del lenguaje del instrumento a partir de su versión en inglés al español, para luego aplicar la nueva versión a un grupo de 420 padres y 420 madres de niños y niñas de cinco ciudades. La evidencia de la estructura interna se evaluó a través de un análisis factorial confirmatorio multigrupo, utilizando el método de máxima verosimilitud para examinar la estructura de los 26 ítems originales. Durante el análisis, se procedió a la eliminación progresiva de los ítems con bajas cargas factoriales hasta encontrar un modelo con adecuados indicadores de ajuste [x 2(531) = 822.82; p < .001; x 2/gl = 1.550; GFI = .90; CFI = .95; TLI = .94; RMSEA = .036, IC 90 % = (.031-.041), p close = 1.000, SRMR = .05]. El resultado fue una escala de 18 ítems distribuidos en las cinco dimensiones originales, cada una con confiabilidad por consistencia interna alfa de Cronbach entre .66 y .78 y coeficientes omega entre .70 y .75. La confiabilidad entre evaluadores estuvo entre .67 y .88. Los alcances y limitaciones del estudio son discutidos teniendo en cuenta la importancia de contar con instrumentos de medición del involucramiento paterno, relativo al materno, que consideren las perspectivas de padres y madres en el contexto peruano.

Abstract The present study seeks to obtain validity and reliability evidence of the Parental Involvement Scale: Care and socialization activities in a sample of Peruvian parents of preschool children. For this purpose, the instrument was translated and linguistically harmonized from its English version into Spanish and then applied to a group of 420 fathers and 420 mothers of children from five cities. Evidence of the internal structure was evaluated through a multigroup confirmatory factor analysis, using the maximum likelihood method to examine the structure of the original 26 items. Items with low factor loadings were progressively eliminated until a model with adequate fit indicators was found [x 2 (531) = 822.82; p <0,001; x 2 /gl = 1.550; GFI = .90; CFI = .95; TLI = .94; RMSEA = .036, IC del 90% (.031 - .041), p close = 1.000, SRMR = .05]. The result was a18-items scale distributed in the five original dimensions, each with Cronbach's alpha internal consistency reliability between .66 and .78 and Omega coefficients between .70 and .75. Inter-rater reliability was between .67 and .88. The scope and limitations of the study are discussed considering the relevance of having instruments to measure paternal involvement relative to maternal involvement, that consider the perspectives of fathers and mothers in the Peruvian context.

Abstract Objective To evaluate the results obtained from the surgical treatment of malleolar ankle fractures associated with distal tibiofibular syndesmosis (DTFS) injury submitted to conventional surgical procedure for fracture fixation and DTFS fixation by suture button (SB). Methods Forty-nine patients were retrospectively evaluated, with a mean age of 45 years old and a mean follow-up of 34.1 months. Clinical and functional evaluation was based on the visual analogue scale (VAS) and on the American Foot and Ankle Society Score (AOFAS) for ankle and hindfoot, return to routine activities, and return to sport. Results The postoperative mean AOFAS and VAS were, respectively, 97.06 (confidence interval [CI 95%: 95.31-98.81] and 0.16 [CI 95% 0,04 - 0,29]. All patients returned to previous daily activities, and only 12 showed some residual symptom. There was no postoperative instability in any patient. Forty-six patients returned to sports activities and, of these, only 1 did not return to the level prior to the injury. Only two patients presented SB-related alterations. There was no report of dissatisfaction. Conclusion In malleolar fractures of the ankle with DTFS injury, the fixation of syndesmosis with SB demonstrated excellent postoperative results. Level of Evidence IV, retrospective case series.

Abstract Aim: identify the possible economic benefit of implementing the measurement of placental alpha 1 microglobulin in users with suspected Preterm Labor Threat, who access the emergency service of the Hospital de The Women Dr. Adolfo Carit Eva, as a mechanism to impact on maternal and infant mortality and economic resources in the Costa Rican Social Security Fund. Methods: economic study, quantitative-retrospective approach, with cross-sectional design. This study included the consult of secondary sources of the Department of Medical Records and Statistics of the Hospital; where the cost of care for hospitalized patients diagnosed with ICD-10 “False Labor before 37 weeks” is calculated; compared to a hypothetical scenario where the qualitative measurement of placental alpha 1 microglobulin is implemented for this same health event. For the data analysis, both individual and collective costs were determined in diagnostic control tests, as well as hospital and medical treatment costs, which allowed estimating the individual, total and average costs of admission of these users. To calculate the costs of suspected Preterm Labor Treat ruled out, the following scenarios were proposed: hospitalization of all patients in whom a possible Preterm Labor Treat is suspected (n= 60) and use of the qualitative placental alpha1 microglobulin test, taking into account their negative predictive value (97%). Subsequently, the value of the cost/savings ratio is estimated (interpreted as beneficial if it is less than 1 and not beneficial otherwise). Results: An incidence of preterm delivery of 10.1% was reported; the costs derived from the care of patients with suspected preterm delivery come mainly from hospitalization. Therefore, when developing the respective cost analysis, it is evident that the economic benefit of to incorporate qualitative measurement of placental alpha 1 microglobulin is derived mainly from the decrease in hospitalization. A minimum cost per patient of 3,317,071.21 colones is obtained, which translates to 5,593.79 dollars at the exchange rate in force on November 30, 2019 according to the Central Bank of Costa Rica. For its part, a maximum cost of 6,356,780.1 colones is estimated, which translates to 11,219.96 dollars at the exchange rate in effect on November 30, 2019. Therefore, once the assumed scenario of the implementation of the placental alpha1 microglobulin test in patients who consult the Emergencies for suspected Preterm Labor Threat has been determined, there is a potential effective saving of resources. Conclusion: the use of the qualitative measurement of placental alpha 1 microglobulin, as an auxiliary diagnostic test in the management of the suspected threat of preterm delivery, it is recommended, from take the negative predictive value as a reference. However, it is necessary to carry out complementary studies to estimate the positive predictive value and other economic studies to include this test in the care algorithm of the Preterm Labor Threat.

Resumen Objetivo: identificar el potencial beneficio económico de implementar la medición de microglobulina alfa 1 placentaria en las usuarias con sospecha de amenaza de parto pretérmino que acceden al Servicio de Emergencias del Hospital de las Mujeres Dr. Adolfo Carit Eva, como mecanismo para la reducción del impacto en la mortalidad maternoinfantil y optimizar recursos económicos en la Caja Costarricense de Seguro Social. Métodos: estudio económico, de enfoque cuantitativo-retrospectivo, con diseño transversal. Se consultaron fuentes secundarias del Departamento de Registros Médicos y Estadística del Hospital de las Mujeres Dr. Adolfo Carit Eva y se calculó el costo de atención de las pacientes hospitalizadas por diagnóstico de “trabajo de parto falso antes de las 37 semanas completas de gestación”, según la Clasificación Estadística Internacional de Enfermedades y Problemas Relacionados con la Salud, décima revisión (CIE-10), en comparación con el hipotético escenario de que, en el mismo evento de salud, se implemente la medición cualitativa de microglobulina alfa 1 placentaria. Para el análisis de los datos se determinaron los costos tanto individuales como colectivos en pruebas diagnósticas de control, así como el costo hospitalario y de tratamiento médico, lo cual permitió estimar los costos individuales, totales y promedio del ingreso innecesario de estas usuarias. Para el cálculo de costos de sospecha de amenaza de parto pretérmino descartada, se plantearon los siguientes escenarios: internamiento de la totalidad de pacientes con sospecha de una posible amenaza de parto pretérmino (n=60) y la utilización de la prueba cualitativa de microglobulina alfa1 placentaria, tomando en consideración su valor predictivo negativo (97%). Posteriormente, se estimó el valor del cociente costo/ahorro (el cual se interpreta como beneficioso en caso de ser menor a 1 y no beneficioso en caso de ser mayor a 1). Resultados: se reportó una incidencia de parto pretérmino de 10,1%; los costos derivados de la atención a pacientes con sospecha de parto pretérmino provienen principalmente de la hospitalización. Se obtiene un costo mínimo por paciente de ¢3 317 071,21 colones que se traducen a $5 593,79 USD según tipo de cambio vigente el 30 de noviembre del 2019, de acuerdo con el Banco Central de Costa Rica. Por su parte, se estima un costo máximo de 6 356 780, 1 colones, lo que equivale a 11 219,96 USD al tipo de cambio vigente el 30 de noviembre del 2019. Por lo cual, una vez determinado el supuesto escenario de la implementación de la prueba de microglobulina alfa 1 placentaria en las pacientes que consultan a Emergencias por sospecha de amenaza de parto pretérmino, se demuestra que existe un potencial ahorro efectivo de recursos. Conclusión: Se recomienda tomar como referente el valor predictivo negativo de microglobulina alfa 1 placentaria en su medición cualitativa, como prueba diagnóstica auxiliar en el manejo de la sospecha de amenaza de parto pretérmino. Empero, es necesario efectuar estudios complementarios para estimar el valor predictivo positivo y otros estudios económicos para valorar la incorporación de esta prueba en el algoritmo de atención de las amenazas de parto pretérmino.

Resumo Justificativa e objetivos: Na artroscopia de ombro em regime ambulatorial, o paciente necessita de um bom controle da dor pós-operatória, que pode ser conseguido por meio de bloqueios regionais. A dexametasona perineural pode prolongar o efeito desses bloqueios. O objetivo deste estudo foi avaliar o efeito da dexametasona perineural quanto ao prolongamento do bloqueio sensitivo no período pós-operatório para cirurgia artroscópica de ombro em regime ambulatorial. Métodos: Após aprovação do Comitê de Ética em Pesquisa e consentimento informado, foram incluídos no estudo pacientes submetidos a cirurgia artroscópica de ombro sob anestesia geral e bloqueio de plexo braquial interescalênico guiado por ultrassonografia. Eles foram randomizados nos Grupo D - bloqueio com 30 mL de levobupivacaína 0,5% com vasoconstritor e 6 mg (1,5 mL) de dexametasona, e Grupo C - bloqueio com 30 mL de levobupivacaína 0,5% com vasoconstritor e 1,5 mL solução salina. A duração do bloqueio sensitivo foi avaliada em quatro momentos pós-operatórios (0, 4, 12 e 24 horas), assim como a necessidade de analgesia de resgate, incidência de náuseas e vômitos e Escala Visual Analógica de Dor (EVA). Resultados: Setenta e quatro pacientes foram randomizados e 71 completaram o estudo (Grupo C, n = 37; Grupo D, n = 34). Observou-se um prolongamento do tempo médio de bloqueio sensitivo no Grupo D (1440 ± 0 min vs. 1267 ± 164 min; p< 0,001). Pacientes do Grupo C apresentaram maior média de escore de dor de acordo com a EVA (2,08 ± 1,72vs. 0,02 ± 0,17; p< 0,001) e um maior número de pacientes solicitou analgesia de resgate nas primeiras 24 horas (68,4%vs.0%; p< 0,001). A incidência de náuseas e vômitos não foi estatisticamente significante. Conclusão: A dexametasona perineural prolongou significativamente o bloqueio sensitivo da levobupivacaína no bloqueio de plexo braquial interescalênico, reduziu a intensidade de dor e a necessidade de analgesia de resgate pelo paciente no período pós-operatório.

Abstract Background and objectives: In shoulder arthroscopy, on an outpatient basis, the patient needs a good control of the postoperative pain that can be achieved through regional blocks. Perineural dexamethasone may prolong the effect of these blocks. The aim of this study was to evaluate the effect of perineural dexamethasone on the prolongation of the sensory block in the postoperative period for arthroscopic shoulder surgery in outpatient setting. Methods: After approval by the Research Ethics Committee and informed consent, patients undergoing arthroscopic shoulder surgery under general anesthesia and ultrasound-guided interscalene brachial plexus block were randomized into Group D - blockade performed with 30 mL of 0.5% levobupivacaine with vasoconstrictor and 6 mg (1.5 mL) of dexamethasone and Group C - 30 mL of 0.5% levobupivacaine with vasoconstrictor and 1.5 mL of 0.9% saline. The duration of the sensory block was evaluated in 4 postoperative moments (0, 4, 12 and 24 hours) as well as the need for rescue analgesia, nausea and vomiting incidence, and Visual Analog Pain Scale (VAS). Results: Seventy-four patients were recruited and 71 completed the study (Group C, n = 37; Group D, n = 34). Our findings showed a prolongation of the mean time of the sensitive blockade in Group D (1440 ± 0 min vs. 1267 ± 164 min, p < 0.001). It was observed that Group C had a higher mean pain score according to VAS (2.08 ± 1.72 vs. 0.02 ± 0.17, p < 0.001) and a greater number of patients (68.4% vs. 0%, p < 0.001) required rescue analgesia in the first 24 hours. The incidence of postoperative nausea and vomiting was not statistically significant. Conclusion: Perineural dexamethasone significantly prolonged the sensory blockade promoted by levobupivacaine in interscalene brachial plexus block, reduced pain intensity and rescue analgesia needs in the postoperative period.

RESUMO O objetivo do estudo foi avaliar o efeito da fotobiomodulação associada a exercícios na dor e na funcionalidade de pacientes com osteoartrite de joelho. Para isso foram recrutados 20 pacientes com osteoartrite do joelho uni ou bilateral, que foram distribuídos em dois grupos: grupo-controle (GC), que realizou aplicação de fotobiomodulação (FBM) placebo e um protocolo de exercício; e grupo fotobiomodulação (GF), que realizou aplicação ativa da FBM e o protocolo de exercício, sendo esse realizado duas vezes por semana durante oito semanas e consistindo de alongamentos passivos dos músculos de membros inferiores, straight leg raise, treinamento proprioceptivo e exercícios para o controle da marcha. A FBM foi aplicada com o aparelho cluster contendo quatro diodos de 670 nm e cinco diodos de 850 nm, com uma potência de saída de 540 mW, sendo a dose utilizada de 4 J/cm2. Os grupos foram avaliados pré e pós-tratamento com os questionários SF-36, Lequesne, Tinetti, e por meio da Escala Visual Analógica de dor (EVA). Os dados foram analisados com o método Anova, seguido do Bonferroni. Os dados indicaram melhoras significativas para o GF ao fim do tratamento para as avaliações da EVA (2±1,25 vs. 0,7±0,82; p=0,009). Embora ambos os grupos tenham obtido melhoras significativas ao longo do tratamento, não foi possível observar diferenças significativas entre eles para o restante das avaliações ao final do tratamento. Portanto, conclui-se que o uso da FBM associada a exercícios apresentou melhora da dor nos pacientes com osteoartrite de joelho, embora não tenha sido possível observar diferenças significativas no que diz respeito à funcionalidade.

ABSTRACT Our study evaluated the effect of photobiomodulation associated with exercise on pain and functionality of patients with knee osteoarthritis. Twenty patients with unilateral or bilateral knee osteoarthritis were selected and divided into two groups: Control group (CG), which underwent photobiomodulation (PBM) placebo and exercise protocol; and the photobiomodulation group (PG), which performed an active application of the PBM and the exercise protocol - performed twice a week for eight weeks and consisting of passive stretching of the lower extremity muscles, straight leg raise, proprioceptive training and exercises for gait control. PBM was applied through a cluster apparatus containing four diodes of 670 nm and five diodes of 850 nm, with an output power of 540 mW and with a dose of 4J / cm2. The groups were evaluated before and after treatment with the SF-36, Lequesne and Tinetti questionnaires as well as the Visual Analog Pain Scale. Data were analyzed using the Anova method, followed by the post-hoc Bonferroni test. The data indicated significant improvements in the PG at the end of treatment for Visual Analog Pain Scale (2±1.25 vs. 0.7±0.82, p=0.009). Although both groups achieved significant improvements throughout the treatment, we could not observe significant differences between them for the rest of the evaluations at the end of the treatment. Therefore, the use of PBM associated with exercises showed pain improvement in patients with knee osteoarthritis, although it was not possible to observe significant differences in patients’ functionality.

RESUMEN El presente estudio tuvo como objetivo evaluar el efecto de la fotobiomodulación asociada a ejercicios sobre el dolor y la funcionalidad de pacientes con osteoartritis de rodilla. Para ello, se reclutaron a 20 pacientes con osteoartritis de rodilla unilateral o bilateral, que se dividieron en dos grupos: el grupo control (GC), que recibió placebo de fotobiomodulación (FBM) y un protocolo de ejercicio; y el grupo de fotobiomodulación (GF), que recibió la aplicación activa de FBM y el protocolo de ejercicio, el cual se realizó dos veces por semana, durante ocho semanas, y consistió en estiramientos pasivos de los músculos de las extremidades inferiores, straight leg raise, entrenamiento propioceptivo y ejercicios para el control de la marcha. La FBM se aplicó con el dispositivo cluster que contenía cuatro diodos de 670 nm y cinco diodos de 850 nm, con una potencia de salida de 540 mW, y la dosis utilizada fue de 4 J/cm2. Los grupos se evaluaron antes y después del tratamiento por medio de los cuestionarios SF-36, Lequesne, Tinetti y de la Escala Visual Analógica de Dolor (EVA). Los datos se analizaron utilizando el método Anova, seguido del Bonferroni. Los datos apuntaron una mejora significativa en el GF al final del tratamiento mediante las evaluaciones de la EVA (2±1,25 vs. 0,7±0,82; p=0,009). A pesar de que ambos grupos lograron obtener mejoras significativas durante el curso del tratamiento, no fue posible observar diferencias significativas entre ellos en las evaluaciones al final del tratamiento. Por lo tanto, se concluye que el uso de la FBM asociada a ejercicios ocasionó una mejora del dolor en pacientes con osteoartritis de rodilla, aunque no fue posible observar diferencias significativas con respecto a la funcionalidad.

ABSTRACT This work aimed to characterize 20 isolates obtained from upland rice plants, based on phenotypic (morphology, enzymatic activity, inorganic phosphate solubilization, carbon source use, antagonism), genotypic assays (16S rRNA sequencing) and plant growth promotion. Results showed a great morphological, metabolic and genetic variability among bacterial isolates. All isolates showed positive activity for catalase and protease enzymes and, 90% of the isolates showed positive activity for amylase, catalase and, nitrogenase. All isolates were able to metabolize sucrose and malic acid in contrast with mannitol, which was metabolized only by one isolate. For the other carbon sources, we observed a great variability in its use by the isolates. Most isolates showed antibiosis against Rhizoctonia solani (75%) and Sclerotinia sclerotiorum (55%) and, 50% of them showed antibiosis against both pathogens. Six isolates showed simultaneous ability of antibiosis, inorganic phosphate solubilization and protease activity. Based on phylogenetic analysis of the 16S rRNA gene all the isolates belong to Bacillus genus. Under greenhouse conditions, two isolates (S4 and S22) improved to about 24%, 25%, 30% and 31% the Total N, leaf area, shoot dry weight and root dry weight, respectively, of rice plants, indicating that they should be tested for this ability under field conditions.

Abstract: Objective: To report prevalence of severe child functional difficulties and disability (CFD) in a nationally representative sample of 2 to 17 year-old children in Mexico and describe the inequities faced by children with CFD in relation to a set of Sustainable Development Goals (SDG)-related outcomes. Materials and methods: Using data from the National Survey of Children and Women (ENIM 2015) we estimate prevalence with 95% confidence intervals for the selected indicators. We use chi-square test and confidence intervals inspection to report significant differences between children with and without CFD. Results: 8% of children present at least one CFD. CFD is associated with higher prevalence of underweight and child labor and lower prevalence of adequate early child development. Conclusion. Children with CFD present worst outcomes and require targeted efforts to ensure they meet health and wellbeing targets in the frame of the SDGs.

Resumen: Objetivo: Reportar la prevalencia de problemas severos de funcionamiento y discapacidad (CFD) en una muestra representativa de niños y niñas de 2 a 17 años en México y describir las inequidades enfrentadas por los niños y niñas con CFD respecto a un conjunto de indicadores relacionados con los objetivos de desarrollo sustentable (ODS). Material y métodos: A partir de datos de la Encuesta Nacional de Niñas, Niños y Mujeres en México (ENIM 2015), se estiman prevalencias e intervalos de confianza al 95% para indicadores seleccionados. Se usa prueba de ji cuadrada e intervalos de confianza para reportar diferencias significativas entre niños/as con y sin CFD. Resultados: 8% de los niños presentan al menos un CFD. Los CFD se asocian con mayor prevalencia de bajo-peso y trabajo infantil, y con menor prevalencia de desarrollo infantil temprano adecuado. Conclusión: Los niños con CFD presentan resultados desventajosos, y requieren esfuerzos enfocados que garanticen el alcance de las metas de salud y bienestar en el contexto de los ODS.

Objetivo:Correlacionar a obesidade com os parâmetros radiográficos do equilíbrio sagital espinhal e espinopélvico em pacientes submetidos à artrodese da coluna vertebral, além de correlacionar a obesidade com o resultado clínico de tais pacientes.Métodos:Estudo observacional, retrospectivo, que incluiu pacientes submetidos a artrodese da coluna vertebral, com período de seguimento mínimo de três meses. Medimos a circunferência abdominal, assim como a altura e o peso, para o cálculo do índice de massa corporal (IMC) e obtivemos radiografias da coluna total. Os parâmetros clínicos estudados foram: dor pela escala visual analógica (EVA) e o questionário de Oswestry (ODI). Correlacionamos obesidade com os parâmetros radiográficos do equilíbrio sagital e espinopélvico e com os parâmetros clínicos pós-operatórios.Resultados:Foram analisados 32 pacientes. Quanto maior o IMC, maior foi o valor da EVA encontrado, porém sem significância estatística (p = 0,83). Também não houve correlação entre o IMC e o questionário ODI. Analisando a circunferência abdominal, não houve correlação com EVA ou ODI. Não houve correlação entre IMC ou circunferência abdominal e os parâmetros radiográficos do alinhamento sagital e espinopélvico. Quanto ao resultado pós-operatório, não houve correlação entre as médias do IMC e da circunferência abdominal e o resultado pós-operatório pelo ODI e pela EVA (p = 0,75 e p = 0,7, respectivamente).Conclusões:Os resultados clínicos de pacientes submetidos a artrodese da coluna vertebral não foram alterados pelo IMC e pela circunferência abdominal. Também não se observou correlação entre os parâmetros radiográficos do equilíbrio sagital espinhal e espinopélvico com a obesidade em pacientes previamente submetidos a cirurgia de artrodese da coluna vertebral.

Objective:To correlate obesity with radiographic parameters of spinal and spinopelvic balance in patients undergoing spinal arthrodesis, and to correlate obesity with clinical outcome of these patients.Methods:Observational retrospective study including patients who underwent spinal arthrodesis, with minimum follow-up period of three months. We measured waist circumference, as well as height and weight to calculate body mass index (BMI) and obtained radiographs of the total column. The clinical parameters studied were pain by visual analog scale (VAS) and the Oswestry questionnaire (ODI). Obesity correlated with radiographic parameters of the sagittal and spinopelvic balance and postoperative clinical parameters.Results:32 patients were analyzed. The higher the BMI, the greater the value of VAS found, but without statistical significance (p=0.83). There was also no correlation between BMI and the ODI questionnaire. Analyzing the abdominal circumference, there was no correlation between the VAS and ODI. There was no correlation between BMI or waist circumference and the radiographic parameters of global spinopelvic sagittal alignment. Regarding the postoperative results, there was no correlation between the mean BMI and waist circumference and the postoperative results for ODI and VAS (p=0.75 and p=0.7, respectively).Conclusions:The clinical outcomes of patients who undergone spinal fusion were not affected by the BMI and waist circumference. Also, there was no correlation between radiographic parameters of spinal and spinopelvic sagittal balance with obesity in patients previously treated with arthrodesis of the spine.

Objetivo:Correlacionar la obesidad con los parámetros radiográficos del equilibrio sagital vertebral y espinopélvico en pacientes sometidos a artrodesis vertebral y correlacionar la obesidad con la resultado clínico de estos pacientes.Métodos:Estudio observacional y retrospectivo que incluyó pacientes sometidos a la artrodesis de la columna vertebral con un período de seguimiento mínimo de tres meses. Se midió la circunferencia de la cintura, así como la altura y el peso para calcular el índice de massa corporal (IMC) y se obtuvo radiografías de la columna total. Los parámetros clínicos estudiados fueron el dolor mediante la escala visual analógica (EVA) y el cuestionario de Oswestry (ODI). La obesidad fue correlacionada con los parámetros radiográficos del balance sagital y espinopélvico y parámetros clínicos postoperatorios.Resultados:Se analizaron 32 pacientes. Cuanto mayor sea el índice de masa corporal, mayor será el valor de EVA, pero sin significación estadística (p = 0,83). Tampoco hubo correlación entre el IMC y el cuestionario ODI. Analizando la circunferencia abdominal, no hubo correlación con EVA u ODI. No hubo correlación entre el IMC o la circunferencia de la cintura y los parámetros radiográficos de la alineación sagital y espinopélvica. En cuanto el resultado postoperatorio, no hubo correlación entre la media de IMC y la circunferencia de la cintura y los resultados postoperatorios por el ODI o EVA (p = 0,75 y p = 0,7, respectivamente).Conclusiones:Los resultados clínicos de pacientes sometidos a la artrodesis de la columna vertebral no se vieron afectados por el IMC y la circunferencia de la cintura. Además no había correlación entre los parámetros radiográficos del equilibrio sagital de la columna y el espinopélvico con la obesidad en pacientes previamente tratados con artrodesis de la columna vertebral.

Objectives: Determine the adverse effects of intravenous metoclopramide in the acute treatment of migraine attacks. Patients and methods: Were evaluated patients with a confirmed diagnosis of migraine according to the criteria of the International Headache Society, they attended with migraine crisis to emergency or outpatient neurology. Demographic data were collected and pain intensity was determined by visual analog scale (VAS ) from 0 to 10. Each patient was given intravenous metoclopramide diluted. We determined the efficacy in reducing pain intensity and the side effects. Results: 76 patients were evaluated, of 18 to 56 years old, 77,6 % were women. The average baseline VAS was 8,6 , after receiving metoclopramide EV 80,2 % had a reduction in VAS ≥ 50 %. The 92,1 % of patients had any adverse effects, were the most frequent psychomotor restlessness, drowsiness, insomnia and dizziness. Conclusions: Intravenous metoclopramide is an effective treatment in controlling migraine attacks and produces very common side effects such as psychomotor restlessness, drowsiness, insomnia and dizziness; it should be noted prior to administration.
