Abstract Objective To determine the frequency of radiographic changes in the temporomandibular joint, in a representative population of patients with Juvenile Idiopathic Arthritis (JIA) and to compare with findings in healthy controls matched by sex and age. Patients and Methods One hundred and thirty-seven panoramic radiographies (PR) from JIA patients of a pediatric rheumatology outpatient clinic were prospectively evaluated and compared to 137 PR from healthy individuals. Results 102 (74.5%) JIA patients and 47 (34.3%) controls showed at least one radiological alteration (p < 0.001). The following radiographic alterations were more frequently observed in JIA patients than in controls: erosion (p < 0.001), altered condylar morphology (p < 0.001), disproportion between condylar process and the coronoid process (p < 0.001) and accentuated curve in the antegonial notch (p = 0.002). Twenty patients (14.6%) presented the four radiographic alterations simultaneously compared to only two controls (1.5%) (p < 0.001). Conclusion Due to the difference in the frequency of findings in the PR of patients and controls, we concluded that PR has value as a screening tool. In the presence of major changes in the mandible head in the PR of patients with a confirmed diagnosis of JIA, MRI should be considered to detect an active inflammatory process in this joint. joint (JIA age thirtyseven thirty seven (PR 13 individuals 10 74.5% 745 74 5 (74.5% 4 34.3% 343 34 3 (34.3% p 0.001. 0001 0.001 . 0 001 0.001, , 0.002. 0002 0.002 002 0.002) 14.6% 146 14 6 (14.6% 1.5% 15 1 (1.5% tool 74.5 7 (74.5 34.3 (34.3 000 0.00 00 14.6 (14.6 1.5 (1.5 74.

Abstract UVB-irradiation increases the risk of various skin disorders, therefore leading to inflammation and oxidative stress. In this sense, antioxidant-rich herbs such as Rosmarinus officinalis may be useful in minimizing the damage promoted by reactive oxygen species. In this work, we report the efficacy of a R. officinalis hydroethanolic extract (ROe)-loaded emulgel in preventing UVB-related skin damage. Total phenols were determined using Folin-Ciocalteu assay, and the main phytocomponents in the extract were identified by UHPLC-HRMS. Moreover, in vitro sun protection factor (SPF) value of ROe was also assessed, and we investigated the in vivo protective effect of an emulgel containing ROe against UVB-induced damage in an animal model. The ROe exhibited commercially viable SPF activity (7.56 ± 0.16) and remarkable polyphenolic content (24.15 ± 0.11 mg (Eq.GA)/g). HPLC-MS and UHPLC-HRMS results showcased that the main compounds in ROe were: rosmarinic acid, carnosic acid and carnosol. The evaluation of the in vitro antioxidant activity demonstrated a dose-dependent effect of ROe against several radicals and the capacity to reduce iron. Therefore, we demonstrated that topical application of the formulation containing ROe inhibited edema formation, myeloperoxidase activity, GSH depletion and maintained ferric reducing (FRAP) and ABTS scavenging abilities of the skin after UVB exposure.

Resumen Objetivo: El objetivo primario fue conocer la actual aplicación de instrumentos de evaluación de competencias quirúrgicas en las residencias acreditadas por la AAOT. Como objetivos secundarios, se describieron los tipos de herramientas utilizadas, el conocimiento de los diferentes instrumentos de evaluación y qué tipo de evaluación se utiliza para la promoción de año. Se analizó si existen diferencias en las características entre las residencias que evalúan las competencias quirúrgicas y las que no. Materiales y Métodos: Se realizó un estudio descriptivo, para lo cual se diseñó una encuesta enfocada en mostrar cuántas residencias evalúan las competencias quirúrgicas con una herramienta formal. Además, a través de ella, se logró responder a los objetivos secundarios. La encuesta se envió a los responsables docentes de las 123 residencias acreditadas por la AAOT. Resultados: Se obtuvieron 105 (85,4%) respuestas, el 59% utiliza algún tipo de herramienta para evaluar las competencias quirúrgicas. Solo el 12,9% de las herramientas utilizadas evalúan las competencias quirúrgicas en forma específica y el resto lo hace con un puntaje general. Un 61% conoce las herramientas disponibles. Para la promoción de año, la mayoría utiliza evaluaciones periódicas múltiples para competencias clínicas y quirúrgicas (63,8% y 67,6%, respectivamente). No hubo diferencias significativas en las características de las residencias que evalúan las competencias quirúrgicas y las que no. Conclusión: El 59% de las residencias implementa algún puntaje o formulario para evaluar las competencias quirúrgicas, solo el 12,9% las evalúa en forma específica, y el resto lo hace con un puntaje subjetivo global.

Abstract Objective: The primary objective was to evaluate the current application of surgical competency (SC) assessment tools in residences accredited by the AAOT. There was also interest in knowing the types of assessment tools used, the knowledge of the different evaluation instruments and what type of evaluation they use for the promotion of the year. We analyzed whether there were differences in the characteristics between the residences that evaluate the SCs and those that do not. Materials and Methods: A descriptive study was carried out, for which a survey was developed focused on assessing how many residences evaluate the SCs with a formal tool. In addition, through the survey it was possible to answer the secondary objectives. It was sent to the chief of residency of the 123 accredited residencies. Results: 105 (85.4%) responses were obtained, 59% (62) used some type of tool for the evaluation of the SC. Only 12.9% (8/62) of the tools used evaluate the SC in a specific way but the majority assed them with a general score. 61% (64/105) know the tools available. For the promotion of the year, the majority use multiple periodic evaluations for clinical and surgical competencies (63.8% and 67.6% respectively). No significant differences were found in the characteristics of the residences that evaluate SC and those that do not. Conclusions: 59% of the residences implement some score or tool for the evaluation of SC, the majority perform the evaluation with a subjective global score. Only the 12.9% evaluate the SC specifically.

Platonia insignis fruit, popularly known as bacuri, is traditionally used in folk medicine for its anti-inflammatory and antioxidant properties. Therefore, this study determined the chemical composition and biological activities of the bacuri’s shell and seeds extracts, considered residues from its consumption and industrial uses. Four biflavonoids (GB-2a, GB-1a, morelloflavone, and volkensiflavone) were identified in the extracts by high-performance liquid chromatography-diode array detection (HPLC-DAD), liquid chromatography tandem mass spectrometry (LC-MS/MS), and liquid chromatography-solid phase extraction-nuclear magnetic resonance (LC-SPE-NMR) techniques. Morelloflavone was identified as the main compound in the shell ethyl acetate extract, being responsible for the high in vitro antioxidant (50% effective concentration (EC50) ranging from 8.0-10.5 µg mL−1 in different protocols), anti-glycant (80%), and moderate inhibition of nitric oxide (1.56 µg mL−1 for > 90% cell viability) activities. This extract showed promising in vivo anti-inflammatory activity evaluated through the paw edema protocol after its incorporation into a liquid-crystalline drug carrier system, reducing the edema by up to 31%. The results demonstrated the potential of the fruit for the development of drugs of natural origin and corroborated to add economic value to these discarded residues.

This study verified the effects of respiratory muscle training (RMT) on hemodynamics, heart rate (HR) variability, and muscle morphology in rats with streptozotocin-induced diabetes mellitus (DM). Thirty-six male Wistar rats were randomized into 4 groups and 34 completed the study: i) sham-sedentary (Sham-ST; n=9); ii) sham-RMT (Sham-RMT; n=9); iii) DM-sedentary (DM-ST; n=8); and iv) DM-RMT (DM-RMT; n=8). Hemodynamics were assessed by central cannulation, and R-R intervals were measured by electrocardiogram. In addition, the effects of RMT on the cross-sectional area of the diaphragm, anterior tibial, and soleus muscles were analyzed. The induction of DM by streptozotocin resulted in weight loss, hyperglycemia, reduced blood pressure, and attenuated left ventricular contraction and relaxation (P<0.05). We also observed a decrease in root mean square of successive differences between adjacent RR intervals (RMSSD) index and in the cross-sectional area of the muscles assessed, specifically the diaphragm, soleus, and anterior tibial muscles in diabetic rats (P<0.05). Interestingly, RMT led to an increase in RMSSD in rats with DM (P<0.05). The induction of DM produced profound deleterious changes in the diaphragmatic and peripheral muscles, as well as impairments in cardiovascular hemodynamics and autonomic control. Nevertheless, RMT may beneficially attenuate autonomic changes and improve parasympathetic modulation.

Resumo Justificativa: A sepse é uma disfunção orgânica fatal com características clínicas inespecíficas que podem imitar outras condições clínicas com quadro hipermetabólico, como a hipertermia maligna. Os cenários são extremamente desafiadores para a anestesia perioperatória e requerem intervenção urgente. Objetivo: Ilustrar a necessidade de intervenção e consulta precoces para uma assistência adicional na abordagem e exclusão de hipertermia maligna e outras possíveis causas durante tal cenário. Relato de caso: Paciente do sexo masculino, 63 anos, submetido à cistoscopia eletiva com cistoscópio flexível e biópsia transretal da próstata guiada por ultrassom sem intercorrências. No pós-operatório, o paciente desenvolveu sintomas que levantaram a suspeita de hipertermia maligna. O protocolo de hipertermia maligna foi imediatamente iniciado, inclusive a administração de dantrolene e uma consulta pela linha direta da associação de hipertermia maligna, juntamente com outros diagnósticos e manejos intervencionistas com vistas ao aprimoramento do paciente. Enquanto a administração precoce de dantrolene ajudou na estabilização hemodinâmica do paciente, a consulta com outros anestesistas e com a Associação de Hipertermia Maligna, juntamente com repetidos exames físicos e laboratoriais, ajudou a excluir a hipertermia maligna como o possível diagnóstico. O paciente recuperou-se mais tarde na unidade de terapia intensiva, onde recebeu tratamento para a bacteremia detectada em suas hemoculturas. Conclusões: A sepse compartilha sintomas clínicos que mimetizam a hipertermia maligna. Enquanto a sepse progride rapidamente para lesões secundárias, a hipertermia maligna é uma ameaça à vida. Proporcionar o tratamento ideal requer um bom julgamento clínico e um alto nível de suspeita quanto aos cuidados oportunos e apropriados, como a administração precoce de dantrolene e a consulta pela linha direta da Associação de Hipertermia Maligna para assistência adicional, que podem resultar em desfechos positivos.

Abstract Background: Sepsis is a life-threatening organ dysfunction with non-specific clinical features that can mimic other clinical conditions with hyper metabolic state such as malignant hyperthermia. Perioperatively anesthesia providers come across such scenarios, which are extremely challenging with the need for urgent intervention. Objective: To illustrate the need for early intervention and consultation for added assistance to approach and rule out malignant hyperthermia and other possible causes during such a scenario. Case report: A 63-year-old male underwent an uneventful elective flexible cystoscopy and transrectal ultrasound-guided prostate biopsy. Postoperatively he developed symptoms raising suspicion for malignant hyperthermia. Immediately malignant hyperthermia protocol was initiated that included administration of dantrolene and consultation of malignant hyperthermia association hotline along with other diagnostic and interventional management aimed at patient optimization. While early administration of dantrolene helped in hemodynamically stabilizing the patient, the consultation with other providers and malignant hyperthermia association hotline along with repeated examinations and lab works helped in ruling out malignant hyperthermia as the possible diagnosis. The patient later recovered in the intensive care unit where he was treated for the bacteremia that grew in his blood cultures. Conclusions: Sepsis shares clinical symptoms that mimic malignant hyperthermia. While sepsis rapidly progresses to secondary injuries, malignant hyperthermia is life threatening. Providing ideal care requires good clinical judgment and a high level of suspicion where timely and appropriate care such as early administration of dantrolene and consultation of malignant hyperthermia association hotline for added assistance can influence positive outcomes.

From the comparative analysis of different scenarios in the simultaneous production of sugar and alcohol, where all the vinasse produced is concentrated at 35ºBrix, energy optimization is feasible, if the composition of the fermented must is solved by a mixture of treated juice, syrup and final molasses, achieving in the latter the maximum concentration of non-sugar solids and low purity. The supply of missing sugars was carried out with the other currents mentioned in order to minimize the dilution to obtain a worth capable of producing the expected product with the maximum concentration of alcohol possible.

A partir del análisis comparativo de diferentes escenarios en la producción simultanea de azúcar y alcohol, donde la totalidad de la vinaza producida es concentrada a 35ºBrix, la optimización energética pudo ser factible al resolverse la composición del mosto fermentado mediante una mezcla de jugo tratado, melado y miel final, logrando en esta última la máxima concentración de sólidos no azúcares y una baja pureza. El aporte de azúcares faltantes se realizó con las otras corrientes mencionadas, de manera tal de minimizar la dilución para lograr un mosto capaz de producir el producto previsto con la máxima concentración de alcohol posible.

Sugar produced for direct consumption or as a raw material for the production of other foods is subject to the control, mainly of the international food industry, of various heavy metals, including iron. The local regulation (Argentine Food Code) do not establish a maximum concentration allowed for it, but its presence in values higher than the specifications of the most demanding buyers may limit the export of such products. On the other hand, the presence of iron in the different points of the process confirms the occurrence of the corrosion phenomenon, responsible for the breakage and wear of equipment, pipes and accessories, sometimes generating unscheduled stops in production. Monitoring at different points of the sugar manufacturing process (defibrated cane, first pressure juice, bagasse, mixed juice, clear juice, lime, sugar liquour and molasses) in a sugar mill of the province of Tucumán during a harvest period, through the iron determination by photocolorimetry, allowed to solve a mass balance for the factory under study, corresponding to a daily milling of 12,000 t of cane, distributing the materials according to the historical values corresponding to the last 5 harvests. For a better interpretation, the sugar scheme was divided into three blocks: juice extraction, physical-chemical treatment and evaporation and vacuum pans, in order to evaluate the changes occurred in each of them and at a general level of the iron contents during sugar cane process. The result of this study, expressed as the difference between the iron contained at system input and output flows, showed a negative value that reflects an average contribution to the process output flows of 16.5 g of iron per ton of cane processed. This type of analysis can help define the type of maintenance to be applied, especially during non harvesting period, in order to minimize the presence of the metal under study in the final product and avoid interruptions during processing.

El azúcar producido para consumo directo o como materia prima para la elaboración de otros alimentos está sujeto al control, principalmente de la industria alimenticia internacional, de diversos metales pesados, entre ellos el hierro. La normativa local (Código Alimentario Argentino) no establece una concentración máxima permitida para este elemento, pero su presencia en valores superiores a las especificaciones de los compradores más exigentes puede limitar la exportación de tales productos. Por su parte, la presencia de hierro en los distintos puntos del proceso confirma la ocurrencia del fenómeno de corrosión, responsable de la rotura y desgaste de equipos, cañerías y accesorios, generando en ocasiones paradas no programadas en la producción. El monitoreo en distintos puntos del proceso de fabricación de azúcar (caña desfibrada, jugo de primera presión, bagazo, jugo mixto, jugo claro, cal, melado y melaza) en un ingenio de la provincia de Tucumán durante un período de zafra, mediante la determinación de hierro por fotocolorimetría, permitió resolver un balance de masa para la fábrica en estudio, correspondiente a una molienda diaria de 12.000 t de caña, distribuyendo los materiales de acuerdo a los valores históricos correspondientes a las últimas cinco zafras. Para una mejor interpretación, el esquema azucarero fue particionado en tres bloques: extracción, tratamiento físico-químico y evaporación y cocimiento, de modo de evaluar los cambios ocurridos en cada uno de ellos y a nivel general de los contenidos de hierro durante el procesamiento. El resultado de este estudio, expresado como la diferencia entre el hierro contenido en las entradas y salidas del sistema, arrojó un valor negativo que refleja un aporte promedio a los flujos de salida del proceso de 16,5 g del elemento por tonelada de caña procesada. Este tipo de análisis puede ayudar a definir el tipo de mantenimiento a aplicar, especialmente durante la interzafra, de modo de minimizar la presencia del metal en estudio en el producto final y evitar a su vez interrupciones durante el procesamiento.

Abstract NUMEN proposes cross sections measurements of Heavy-Ion double charge exchange reactions as an innovative tool to access the nuclear matrix elements, entering the expression of the life time of Neutrinoless double beta decay (0νββ). A key aspect of the projectis the use at INFN-Laboratori Nazionali del Sud (LNS) of the Superconducting Cyclotron (CS) for the acceleration of the required high resolution and low emittance heavy-ion beams and of MAGNEX large acceptance magnetic spectrometer for the detection of the ejectiles. The experimental measurements of double charge exchange reactions induced by heavy ions present a number of challenging aspects, since such reactions are characterized by very low cross sections. First experimental results give encouraging indication on the capability to access quantitative information towards the determination of the Nuclear Matrix Elements for 0νββ decay.

Resumen NUMEN propone mediciones de secciones eficaces de reacciones de intercambio de carga doble de iones pesados como una herramienta innovadora para acceder a los elementos de la matriz nuclear, entrando en la expresión del tiempo de vida de la desintegración beta doble sin neutrino (0νββ). Un aspecto clave del proyecto es el uso en INFN-Laboratori Nazionali del Sud (LNS) del ciclotrón superconductor (CS) para la aceleración de los haces de iones pesados de alta resolución y baja emitancia requeridos y del espectrómetro magnético de gran aceptación MAGNEX para la detección de los residuos eyectados. Las mediciones experimentales de reacciones de intercambio de carga doble inducidas por iones pesados presentan una serie de aspectos desafiantes, ya que tales reacciones se caracterizan por secciones eficaces muy bajas. Los primeros resultados experimentales dan una indicación alentadora sobre la capacidad de acceder a información cuantitativa para la determinación de los Elementos de la Matriz Nuclear para la descomposición de 0νββ.

As perturbações de ansiedade são altamente prevalentes entre crianças em idade escolar. Estas perturbações tendem a seguir um curso crónico e interferem significativamente no funcionamento diário dos jovens. O objetivo principal deste estudo foi examinar as propriedades psicométricas da versão Portuguesa da Escala de Interferência da Ansiedade na Vida da Criança - versões para Pais e Crianças (CALIS-P e CALIS-C). Participaram 132 crianças, com idades entre os 7 e 12 anos, com diagnóstico principal de ansiedade, e seus respetivos pais. A análise fatorial da CALIS-P revelou três fatores que coincidem com as subescalas hipotetizadas: Interferência Em Casa, Fora de Casa e na Vida da Família. Para a CALIS-C, a análise fatorial revelou dois fatores que dizem respeito à Interferência nas Relações Próximas e no Desempenho, que não correspondem às subescalas da versão original. Os estudos psicométricos mostraram uma boa consistência interna para as várias subescalas da CALIS e boas qualidades na validade convergente e divergente. Foi observada ainda uma correlação significativa entre os resultados da CALIS e outra medida de interferência. Estes resultados sugerem que a versão portuguesa da CALIS é uma medida confiável e válida para a avaliação do impacto da ansiedade na criança e no funcionamento familiar.

Anxiety disorders are highly prevalent among school-aged children. These disorders become chronic in a substantial proportion of youths and cause significant interference with daily functioning. The purpose of the current investigation was to examine the psychometric properties of the Portuguese version of the Child Anxiety Life Interference Scale - Parent and Child versions (CALIS-P and CALIS-C). The sample consisted of 132 children between the ages of 7 and 12 with a main diagnosis of anxiety disorder and their parents. A factor analysis of the CALIS-P yielded three factors that agreed with the hypothesised subscales of At Home, Outside Home and Parent Life interference. For the CALIS-C, a factor analysis yielded two factors corresponding to Close Relationships and Performance interference that did not match the subscales of the original version. The internal consistency of the various CALIS subscales was good. Finally, evidence was found for both convergent and divergent validity. The CALIS scores were also significantly correlated with another measure of interference. The results provide initial support that the Portuguese version of the CALIS is a reliable and valid measure for the assessment of the impact of anxiety on child and family functioning.

The objective of this analysis is to reflect on more sustainable family and extensive integrated livestock production models, in which the woody component is integrated, contributing to the reduction of greenhouse gases and favoring the mitigation of the climate change. For such purpose, a revision was made referring to the integration of the forestry activity in livestock production, as a viable alternative of production system. A start is made from the criterion that silvopastoral systems (SPSs), within the agroforestry ones, are agroecosystems in which a tree component is associated with a herbaceous (natural or improved pastures) and a farming component (livestock) in the same site, where biological interactions exist among them and land use is maximized. This paper also describes how SPSs are grouped; their opportunities from the economic, productive, social and environmental points of view; and the effects of the interaction among its components. This analysis allows to state that SPSs are a product of the relation among biology, society and culture, and in them there is a large diversity; likewise, they allow the reconversion of the very little productive extensive livestock production into more productive and sustainable systems, as well as the rehabilitation of the areas degraded by this type of livestock production, deforestation and soil depletion.

El objetivo de este análisis es reflexionar acerca de modelos integrados de producción ganadera familiar y extensiva, más estables y sustentables, en los que se integre el componente leñoso, que contribuye a la reducción de gases con efecto invernadero y favorece la mitigación del cambio climático. Para ello se hizo una revisión de conceptos referentes a la integración de la actividad forestal en la ganadería, como alternativa viable de sistema de producción. Se parte del criterio de que los sistemas silvopastoriles (SSP), dentro de los agroforestales, son agroecosistemas en los que se asocia un componente arbóreo con uno herbáceo (pasturas naturales o mejoradas) y otro pecuario (ganado) en un mismo sitio, donde existen interacciones biológicas entre estos y se maximiza el uso de la tierra. También se describe cómo se agrupan los SSP; sus oportunidades desde los puntos de vista económico, productivo, social y ambiental; y los efectos de la interacción entre sus componentes. Este análisis permite plantear que los SSP son producto de la relación entre la biología, la sociedad y la cultura, y en ellos existe una enorme diversidad; asimismo, permiten la reconversión de la ganadería extensiva de muy baja productividad en sistemas más productivos y sostenibles en el tiempo, así como la rehabilitación de las áreas degradadas por ese tipo de ganadería, por la deforestación y por el agotamiento de los suelos.

BACKGROUND: The mechanism by which high-voltage electrical stimulation (HVPC) acts on edema reduction is unknown. OBJECTIVE: To assess the effect of HVPC with negative polarity (-) applied to the ankle of rats with acute joint inflammation. METHOD: Sixty-four rats were divided into four groups (n=16): inflamed+HVPC(-), 0.03 mL application of ι-carrageenan (3%) to the tibiotarsal joint plus HVPC(-); inflamed+HVPC placebo, carrageenan application and HVPC placebo; normal+HVPC(-), HVPC application(-); and normal control, no intervention. The HVPC(-) 100 Hz at a submotor level was applied daily for 45 min on three consecutive days. The variables were pain, hind-foot volume, and serum histamine and albumin assessed before and during the 48 hours following inflammation. The variables were compared using the t test, one-way ANOVA, nested ANOVA for repeated measures, and the post hoc Bonferroni test. Analysis of covariance was applied to adjust the effects of HVPC(-) by measurements of pain, inflammation, albumin, and histamine at 24 h, and the final weight was compared to the other groups. The significance level was set at p<0.05. RESULTS: There were no differences between the inflamed+HVPC(-) and inflamed+HVPC placebo groups in terms of pain or edema (p>0.05). Albumin was reduced in the groups that received the intervention, but there was no differences between them. There was only a 24 hour increase in histamine with the normal+HVPC(-) (p=0.0001) and inflamed+HVPC placebo groups (p=0.01) compared to the normal control group. CONCLUSIONS: The results of the present study suggest that HVPC(-) with the parameters employed did not reduce pain or edema and did not change serum albumin or histamine levels,, which indicates the inability of this resource to have a positive effect when treating treat acute joint inflammation.
