RESUMEN
Introduction: Non-communicable diseases represent a global health burden with increasing prevalence. To prevent or improve this type of diseases, dietary strategies based on healthy foods have been suggested. Cereals are the most consumed foods in the world and preventive effects of whole grains on health have been described. The germ and bran of cereals are abundant in bioactive compounds, including phytochemicals, vitamins, minerals and fibers, and these compounds are effective in preventing and improving non-communicable diseases. This review analyzes the content and distribution of the primary components of whole grains (wheat, barley, oats, rice and black wheat) and their fractions, focusing on the mechanisms by which phenolic acids and dietary fiber contribute to reducing the risk of metabolic and cardiovascular diseases and cancer. There is clear evidence of the broad cellular and physiological effects of bioactive compounds in whole grains, supporting the health value of a diet rich in whole grains.
Introducción: Las enfermedades no transmisibles representan una carga sanitaria mundial con una prevalencia cada vez mayor. Para prevenir o mejorar este tipo de enfermedades se han sugerido estrategias dietéticas basadas en alimentos saludables. Los cereales son los alimentos más consumidos en todo el mundo y se han descrito efectos preventivos de los cereales integrales sobre la salud. El germen y el salvado de los cereales son abundantes en compuestos bioactivos, incluidos fitoquímicos, vitaminas, minerales y fibras, y estos compuestos son eficaces para prevenir y mejorar las enfermedades no transmisibles. En esta revisión se analiza el contenido y distribución de los componentes primarios de los cereales integrales (trigo, cebada, avena, arroz y trigo negro) y sus fracciones, centrándose en los mecanismos por los que los ácidos fenólicos y la fibra dietética contribuyen a disminuir el riesgo de padecer enfermedades metabólicas, cardiovasculares y cáncer. Existen pruebas claras de los amplios efectos celulares y fisiológicos de los compuestos bioactivos de los granos enteros, que respaldan el valor saludable de una dieta rica en cereales integrales.

INTRODUCTION: Holmium laser enucleation of the prostate has rapidly become the gold standard for the surgical treatment of benign prostate hyperplasia, although thulium fiber laser (TFL) has also been postulated as an effective and safe alternative for prostate enucleation. The aim of this study is to describe our initial experience with the TFL for endoscopic enucleation of the prostate. MATERIAL AND METHODS: All patients proposed to TFL prostate enucleation were included in the analysis, regardless their prostate volume, catheter status and severity of symptoms, in 3 centers. Preoperative characteristics, intraoperative times and functional 3-months follow-up variables were collected, along with complications. RESULTS: Fifty-six patients were available, with a mean age of 68.7 years. Enucleation and morcellation efficiencies were 2.04 and 7.47â¯g/min, respectively. Median hospital stay was one day. Comparable functional data, pre and 3-month post-surgery was: mean prostate volume 88.9 vs 21.3â¯g, maximum urinary flow 13.2 vs 27.3â¯ml/s, post-void residual volume 149 vs 7.8â¯ml, prostatic specific antigen level 11.2 vs 1â¯ng/ml, and International Prostate Symptom Score 20.75 vs 3.96. Fourteen out of 56 (25%) patients presented with complications grade ≤2, according to the Clavien-Dindo classification. DISCUSSION: With wider evidence for other urological indications, very recent evidence about the suitability of TFL for prostate enucleation has arisen, since the first case described in 2021. Our results seem to back up these previous successful experiences as long as we obtained good intraoperative and short term follow-up functional results. However, there is still a need of longer follow-up data. CONCLUSIONS: TFL represents a novel technology for prostate enucleation, with a good intraoperative and short follow-up functional results, and a safety profile similar to the observed for those techniques that have been wider used for this indication. Further studies with longer follow-up periods and comparative with these other techniques are necessary.

Objetivo Analizar la información actual sobre la seguridad del láser en la cirugía retrógrada intrarrenal (CRIR), centrándonos en las dos principales tecnologías láser que utilizamos en urología, el láser de holmio:itrio-aluminio-granate (Ho:YAG) y el láser de fibra de tulio (TFL). Métodos Revisión narrativa de los artículos más relevantes publicados en las bases de datos Medline y Scopus sobre este tema. Resultados Los láseres TFL y Ho:YAG con ajustes similares (0,2 J/40 Hz) tienen un aumento de temperatura promedio por volumen similar y la tasa de calentamiento promedio aumenta proporcionalmente a la potencia del láser, especialmente cuando se utilizan frecuencias altas. Datos preclínicos recientes que comparan ambas tecnologías láser con diferentes ajustes del láser coinciden en que cuando la energía suministrada aumenta a expensas de frecuencias más altas, el daño térmico también aumenta. Las frecuencias más altas, a pesar del aumento de temperatura en el medio de irrigación, pueden causar lesiones térmicas accidentales por láser. Conclusiones El uso de ajustes de baja frecuencia y una irrigación adecuada es fundamental para evitar lesiones térmicas en la litotricia endoscópica con láser (LEL). Además, se recomienda el uso de gafas de seguridad láser en la LEL con Ho:YAG y TFL. (AU)
Objective To analyze the current information about laser safety in retrograde intrarenal surgery (RIRS), focusing on the two main laser technologies that we use in urology, the holmium:yttrium-aluminum-garnet (Ho:YAG) laser, and the thulium fiber laser (TFL). Methods Narrative overview of the most relevant articles published in Medline and Scopus databases about this subject. Results TFL and Ho:YAG laser at similar settings (0.2 J/40 Hz) have similar volume-averaged temperature increase and the average heating rate increase proportionally to laser power, especially when high frequencies are used. Recent preclinical data, comparing both laser technologies at different laser settings, agreed that when the delivered energy increases in expenses of higher frequencies, the thermal damage increases too. Higher frequencies, despite of the rise of temperature in the irrigation medium, can cause accidental thermal lasering lesions. Conclusions The use of low frequency settings and a proper irrigation is critical to avoid thermal injury in endoscopic laser lithotripsy (ELL). In addition, the use of laser safety eyeglasses is recommended in Ho:YAG and TFL ELL. (AU)

Los cereales integrales son una categoría de alimentos fundamental para la dieta humana y representan una fuente invaluable de carbohidratos, proteínas, fibras, fitoquímicos, minerales y vitaminas. Muchos estudios han demostrado que el consumo de cereales integrales está relacionado con un menor riesgo de enfermedades crónicas no transmisibles. Sin embargo, varios de sus efectos positivos para la salud parecen desaparecer cuando se refinan los cereales. La pregunta de investigación es cuál sería el efecto de los cereales integrales en la prevención de enfermedades crónicas no transmisibles. Este artículo describe los efectos positivos del consumo de cereales integrales en la prevención de estas enfermedades. Para ello, se realiza una descripción narrativa que revisa los antecedentes disponibles sobre: a) situación epidemiológica en Chile y su relación con la alimentación; b) consumo de cereales integrales en el mundo y en Chile; y c) el efecto del consumo de cereales integrales en la reducción del riesgo de enfermedad cardiovascular. obesidad, diabetes tipo 2 y cáncer. Los antecedentes generales son muy alentadores sobre el efecto positivo del consumo de cereales integrales sobre determinadas enfermedades, especialmente las de origen metabólico. Sin embargo, la incertidumbre de algunas asociaciones negativas merece mayor atención.
Whole grains are a fundamental food category for the human diet and represent an invaluable source of carbohydrates, proteins, fibers, phytochemicals, minerals and vitamins. Many studies have shown that consumption of whole grains is linked to a lower risk of chronic non-communicable diseases. However, several of its positive health effects seem to disappear when grains are refined. The research question is what would be the effect of whole grains in the prevention of Chronic Non-Communicable Diseases. This article describes the positive effects of whole grain consumption in these diseases.To this end, a narrative description is made that reviews the available background on: a) epidemiological situation in Chile and its relationship with diet; b) consumption of whole grains in the world and in Chile; and c) the effect of whole grain consumption on reducing the risk of cardiovascular disease. obesity, type 2 diabetes, and cancer. The general background is very encouraging for a positive effect of whole grain consumption on certain diseases, especially those of metabolic origin. However, the uncertainty of some negative associations deserves further attention.

Este estudo investigou a eficácia biomecânica de infraestruturas de próteses feitas de cobalto-cromo (CoCr) e compósito de fibra de vidro (FVRC), implantadas em mandíbulas edêntulas. A distribuição de densidade foi investigada utilizando um modelo ósseo sintético, equipado com extensômetros, para simular condições anatômicas e biomecânicas humanas. Os implantes de conexão interna cone morse fabricados pela Conexão Sistemas de Próteses, Arujá, São Paulo, Brasil, têm diâmetro e comprimento de 4.0mm e 13mm, respectivamente, e os intermediários protéticos selecionados foram Micro Unit Sólidos da mesma marca para plataforma cone morse, com altura de transmucoso 2,5 mm, foram utilizados para suportar as infraestruturas de próteses híbridas. Por meio de extensometria, mediu-se a deformação óssea sob carga ao redor dos quatro implantes, comparando as performances das infraestruturas CoCr e FVRC. Os resultados revelaram informações importantes sobre a seleção de materiais para infraestruturas de próteses, com foco especiÌfico nas barras de FVRC e CoCr. Os testes "in vitro" e análises estatiÌsticas destacaram que as barras de FVRC produziram menores microdeformações em comparação com as de CoCr sob carga. Essa diferença foi estatisticamente significativa, indicando que a FVRC possui uma capacidade superior de absorver e distribuir carga de maneira mais eficiente. No entanto, ressalta-se a necessidade de estudos futuros, incluindo pesquisas clínicas, para explorar totalmente as implicações desses achados e aprimorar ainda mais as práticas de reabilitação oral com implantes (AU)
This study investigated the biomechanical effectiveness of prosthetic infrastructures made of cobalt-chromium (CoCr) and fiberglass composite (FGC), implanted in edentulous jaws. The density distribution was investigated using a synthetic bone model, equipped with strain gauges, to simulate human anatomical and biomechanical conditions. The morse cone internal connection implants manufactured by Conexão Sistemas de Próteses, Arujá, São Paulo, Brazil, have a length of 4.0mm and 13mm, respectively, and the prosthetic intermediates selected were Micro Unit Solids of the same brand for a morse cone platform, with a transmucosal height of 2.5 mm, were used to support hybrid prosthetic infrastructures. Using extensometry, bone deformation under load around the four implants was measured, comparing with the performance of the CoCr and FGC infrastructures. The results revealed important information about the selection of materials for prosthetic infrastructures, with a specific focus on FGC and CoCr bars. "In vitro" tests and statistical analyzes highlighted that FGC bars produced smaller microdeformations compared to CoCr bars under load. This difference was statistically significant, demonstrating that FGC has a superior capacity to absorb and distribute load more efficiently. However, the need for future studies, including clinical research, is highlighted to fully explore the implications of these findings and further improve oral rehabilitation practices with implants.

Objective: This systematic review aims to compare the clinical longevity of metallic and fiberglass intraradicular posts in teeth with severely compromised crowns, utilizing randomized clinical trials and case reports published in the last eleven years. Material and Methods: The research was conducted on PubMed, Medline, Lilacs, and BBO databases using the first search strategy with the descriptors 'dental posts,' 'longevity,' 'fiberglass-reinforced posts' or 'metallic posts.' The second search strategy involved analyzing the references of articles identified by the first search. Both studies were carried out with stringent inclusion and exclusion criteria. Results: No statistically significant and clinically relevant differences in longevity were observed between metallic and fiberglass posts. Conclusion: The clinical success and durability of the restorative procedure using intraradicular posts primarily depend on the remaining amount around the post (ferrule), the type and position of the tooth in the arch (impacting the masticatory forces exerted on the restored tooth), and the correct application of the cementation technique. It is noteworthy that fiberglass posts offer substantial advantages by presenting a modulus of elasticity similar to dental structure, ensuring a more homogeneous distribution of masticatory forces and reducing the risk of fractures. These findings have practical implications for material selection in restorative procedures involving intraradicular posts.(AU)
Objetivo: Esta revisão sistemática visa comparar a longevidade clínica de pinos intrarradiculares metálicos e de fibra de vidro em dentes com coroas severamente comprometidas, através de estudos clínicos randomizados e relatos de casos, publicados nos últimos onze anos. Material e Métodos: A pesquisa foi conduzida nas bases de dados PubMed, Medline, Lilacs e BBO, utilizando a primeira estratégia de busca com os s 'pinos dentais' e 'longevidade' e 'pinos reforçados com fibra de vidro' ou 'pinos metálicos'. A segunda estratégia de busca consistiu na análise das referências dos artigos identificados pela primeira estratégia. Ambos os estudos foram delineados com critérios rigorosos de inclusão e exclusão. Resultados: Não se constataram diferenças estatisticamente significativas e clinicamente relevantes na longevidade entre pinos metálicos e de fibra de vidro. Conclusão: O êxito clínico e a durabilidade do procedimento restaurador empregando pinos intrarradiculares dependem primordialmente da quantidade de remanescente ao redor do pino (férula), do tipo e posição do dente na arcada (o que impacta nas forças mastigatórias exercidas sobre o dente restaurado) e da aplicação correta da técnica de cimentação.Destaca-se que o pino de fibra de vidro oferece vantagens substanciais ao apresentar módulo de elasticidade similar à estrutura dentária, assegurando uma distribuição mais homogênea das forças mastigatórias e reduzindo o risco de fraturas (AU)

Introducción: La fibra es el tratamiento inicial en el estreñimiento crónico funcional. Sin embargo, su papel en el grupo de pacientes con disinergia defecatoria no está bien establecido. El objetivo del estudio es evaluar la eficacia y la seguridad de la dieta alta en fibra en pacientes con disinergia defecatoria en el tratamiento con biofeedback anorrectal. Pacientes y métodos: Se realizó un ensayo clínico exploratorio, aleatorizado (1:1), doble ciego, controlado add-on, en un centro de referencia en España en pacientes con estreñimiento funcional y disinergia defecatoria de acuerdo con criterios de ROMAIV. Grupo control: tratamiento con biofeedback y dieta baja en fibra (15-20g/día). Grupo experimental: tratamiento con biofeedback y dieta alta en fibra (25-30g/día). Se analizó: respondedor (variable principal), paciente en quien la disinergia defecatoria se había corregido (>20% de reducción de la presión anal durante la maniobra defecatoria y prueba de expulsión del balón normal); parámetros anorrectales (relajación anal, reducción del esfuerzo); seguridad (síntomas abdominales: flatulencia, dolor, borborigmo, distensión). Resultados: Un total de 44 pacientes fueron aleatorizados: 22 por grupo. El porcentaje de respondedores fue del 75% (15/20; IC95%: 53-89%) grupo control y 70% (14/20; IC95%: 48-85%) grupo experimental, p=0,225. Solo se observaron diferencias a favor del grupo control en síntomas abdominales: flatulencias (p=0,028), distensión abdominal (p=0,041) y bienestar digestivo (p=0,043). Conclusión: En pacientes con disinergia defecatoria la dieta alta en fibra no solo no mejora la eficacia del biofeedback anorrectal, sino que se asocia a una pérdida de la mejoría de los síntomas abdominales.

Introduction: Fiber is the initial treatment in chronic functional constipation. However, its role in the group of patients with defecatory dyssynergy is not well established. The objective of the study is to evaluate the efficacy and safety of a high fiber diet in patients with defecatory dyssynergy in the treatment with anorectal biofeedback. Patients and methods: An exploratory, randomized (1:1), double-blind, controlled «add-on» clinical trial was carried out in a reference center in Spain in patients with functional constipation and defecatory dyssynergy according to the ROMEIV criteria. Control group: treatment with biofeedback and low-fiber diet (15-20g/day). Experimental group: treatment with biofeedback and high fiber diet (25-30g/day). Analyzed: responder (primary endpoint), patient whose defecatory dyssynergy had been corrected (>20% reduction in anal pressure during the defecation maneuver and normal balloon expulsion test); anorectal parameters (anal relaxation, reduced straining); safety (abdominal symptoms: flatulence, pain, borborygmus, bloating). Results: A total of 44 patients were randomized: 22 per group. The percentage of responders was 75% (15/20; 95%CI: 53 89%) control group and 70% (14/20; 95%CI: 48-85%) experimental group, P=.225. Differences in favor of the control group were only observed in abdominal symptoms: flatulence (P=.028), abdominal distension (P=.041) and digestive comfort (P=.043). Conclusions: In patients with defecatory dyssynergy, a high-fiber diet not only does not improve the efficacy of anorectal biofeedback but is associated with a loss of improvement in abdominal symptoms.

Abstract The nerve terminal and muscle membrane compose the neuromuscular junction. After opening the voltage-gated calcium channels, action potentials from the motor axons provoke a cascade for the acetylcholine release from synaptic vesicles to the synaptic cleft, where it binds to its receptor at the muscle membrane for depolarization. Low amplitude compound muscle action potential typically presents in presynaptic disorders, increasing by more than 100% after a 10-second effort in the Lambert-Eaton myasthenic syndrome and less in botulism. Needle electromyography may show myopathic motor unit action potentials and morphological instability ("jiggle") due to impulse blocking. Low-frequency repetitive nerve stimulation (RNS) is helpful in postsynaptic disorders, such as myasthenia gravis and most congenital myasthenic syndromes, where the number of functioning acetylcholine receptors is reduced. Low-frequency RNS with a decrement >10% is abnormal when comparing the 4th to the first compound muscle action potential amplitude. High-frequency RNS is helpful in presynaptic disorders like Lambert-Eaton myasthenic syndrome, botulism, and some rare congenital myasthenic syndromes. The high-frequency RNS releases more calcium, increasing the acetylcholine with a compound muscle action potential increment. Concentric needle records apparent single-fiber action potentials (spikes). A voluntary activation measures the jitter between spikes from two endplates. An electrical activation measures the jitter of one spike (one endplate). The jitter is the most sensitive test for detecting a neuromuscular junction dysfunction. Most neuromuscular junction disorders are responsive to treatment.
Resumo O nervo terminal e a membrana muscular compõem a junção neuromuscular. Após a abertura dos canais de cálcio dependentes de voltagem, os potenciais de ação do axônio motor provocam uma cascata de eventos que libera acetilcolina das vesículas para a fenda sináptica, ligando-se ao receptor na membrana muscular para despolarização. O potencial de ação muscular composto de baixa amplitude ocorre nas desordens pré-sinápticas, aumentando em mais de 100% após esforço de 10 segundos na síndrome miastênica de Lambert-Eaton e menos no botulismo. A eletromiografia pode mostrar potenciais de ação da unidade motora miopáticos e instabilidade morfológica ("jiggle") devido ao bloqueio do impulso. Estimulação nervosa repetitiva (ENR) de baixa frequência é útil nos distúrbios pós-sinápticos, como miastenia gravis e a maioria das síndromes miastênicas congênitas, quando há número reduzido de receptores de acetilcolina funcionantes. ENR de baixa frequência com decremento >10% é anormal comparando-se à amplitude do quarto com o primeiro potencial de ação muscular composto. ENR de alta frequência é útil nas doenças pré-sinápticas, como síndrome miastênica de Lambert-Eaton, botulismo e algumas síndromes miastênicas congênitas raras. ENR de alta frequência libera mais cálcio, aumenta acetilcolina, resultando em incremento do potencial de ação muscular composto. O eletrodo de agulha concêntrico registra potenciais de ação aparente de fibra única (PAAFU). Ativação voluntária mede jitter entre dois PAAFUs (duas junções neuromusculares). Ativação elétrica mede jitter de um PAAFU (uma junção neuromuscular). Jitter é o teste mais sensível para detectar disfunção de junção neuromuscular. A maioria dos distúrbios juncionais é responsiva ao tratamento.
RESUMEN
Introducción. La calidad de los carbohidratos consumidos juega un papel importante en la prevención de las enfermedades crónicas no transmisibles (ECNT). Objetivo. Analizar el índice de calidad de los carbohidratos (ICC) en la población urbana costarricense y su relación con las variables sociodemográficas, antropométricas y la calidad y la diversidad de la dieta. Materiales y métodos. Los datos provienen del Estudio Latinoamericano de Nutrición y Salud, en una muestra representativa de 798 personas entre 15 y 65 años que residen en zonas urbanas de Costa Rica (2014- 2015). En una visita domiciliaria se administró un cuestionario para recolectar los datos sociodemográficos y se pesó y midió a los participantes. El consumo dietético se obtuvo mediante dos recordatorios de 24 horas en días no consecutivos. El ICC se calculó mediante el consumo de fibra, el índice glicémico, la relación carbohidratos sólidos/líquidos y la relación granos enteros/granos totales. Se comparó el ICC según el sexo, el grupo de edad, el nivel socioeconómico, el estado nutricional, la circunferencia de cintura y la calidad y diversidad de la dieta de los participantes. Resultados. El ICC se asoció positivamente con un mayor consumo de energía, carbohidratos totales, proteínas, grasas, colesterol, frutas, vegetales y leguminosas (p<0,001). Un mayor ICC se asoció positivamente con un mayor porcentaje de adecuación de micronutrientes y mayor índice de diversidad y calidad de la dieta (p<0,001), así como con un menor índice de masa corporal y una menor circunferencia de cintura al ajustar por sexo y edad (p<0,005). Conclusiones. El presente estudio demostró que un mayor ICC se asocia significativamente con mejores indicadores dietéticos e índice de masa corporal, por lo que resulta fundamental establecer en Costa Rica pautas dietéticas que permitan aumentar la calidad de los carbohidratos de la dieta con el fin de contribuir en la prevención de las ECNT(AU)
Introduction. The carbohydrate quality index (CQI) plays an important role in the prevention of chronic non-communicable diseases (NCD) and adequate macro and micronutrient intake. Objective. To analyze the carbohydrate quality index (CCI) in the Costa Rican urban population and its relationship with sociodemographic and anthropometric variables and the quality and diversity of the diet. Materials and methods. Data come from the Latin American Nutrition and Health Study (ELANS), in a representative sample of 798 people between 15 and 65 years of age who reside in urban areas of Costa Rica (2014-2015). During a home visit, a questionnaire was administered to collect sociodemographic data, and participants were measured and weighed. Dietary intake was obtained through two 24-hour recalls in non- consecutive days. The CQI was calculated using fiber intake, glycemic index, liquid/solid carbohydrate ratio, and whole grain/total grains. CCI was then compared according to sex, age-group, socioeconomic level, nutritional status and diet quality and diet diversity. Results. The CQI was positively associated with energy intake, total carbohydrates, proteins, fats, cholesterol, fruits, vegetables, and legumes (p<0,001). Also, CQI was associated with a higher percentage of micronutrient adequacy and diet quality and diversity (p<0,001), as well as with a lower body mass index and lower waist circumference when adjusting for sex and age (p<0,005). Conclusions. The present study showed that higher CQI is associated with better dietary and body mass index, which shows that it is essential to establish dietary guidelines for public health in Costa Rica that allows increasing the quality of carbohydrates in the diet to contribute to the prevention of chronic NCD(AU)

Objective: this study aimed to evaluate whether low-salt low-protein diet (LPD) supplemented with 10 g of inulin could lower serum toxin levels in patients with chronic kidney disease (CKD), thereby providing evidence for adjusting dietary prescriptions of inhospital patients and outpatient nutrition consultants. Methods: we randomized 54 patients with CKD into two groups. Dietary protein intake compliance was evaluated using a 3-day dietary diary and 24-h urine nitrogen levels. The primary outcomes were indoxyl sulfate (IS) and p-cresyl sulfate (PCS), and secondary outcomes included inflammation marker levels, nutritional status, and renal function. We assessed 89 patients for eligibility, and a total of 45 patients completed the study, including 23 and 22 in the inulin-added and control groups, respectively. Results: PCS values decreased in both groups after intervention: inulin-added group, ∆PCS -1.33 (-4.88, -0.63) μg/mL vs. LPD group, -4.7 (-3.78, 3.69) μg/mL (p = 0.058). PCS values reduced from 7.52 to 4.02 μg/mL (p < 0.001) in the inulin-added group (p < 0.001). Moreover, IS decreased from 3.42 (2.53, 6.01) μg/mL to 2.83 (1.67, 4.74) μg/mL after adding inulin; ∆IS was -0.64 (-1.48, 0.00) μg/mL, and a significant difference was observed compared with the control group (p = 0.004). The inflammation index decreased after intervention. Conclusion: dietary fiber supplementation may reduce serum IS and PCS levels and modulate their inflammatory status in predialysis CKD patients.(AU)

SUMMARY: The preserved form of all components of the nerve fiber is a prerequisite for the proper conduction of the nerve impulse. various factors can change the shape of nerve fibers. In everyday practice, qualitative histological analysis is the gold standard for detecting changes in shape. Geometric morphometry is an innovative method that objectively enables the assessment of changes in nerve fibers' shape after local anesthetics action. A total of sixty sciatic nerves were used as material, which was intraneural injected with saline solution in the control group (n=30), and a solution of 1.33 % liposomal bupivacaine (n=30) in the test group. After the animals were sacrificed, nerve samples were taken and histological preparations were made. The preparations were first described and examined using a qualitative histological method, after which digital images were made. The images were entered into the MorphoJ program and processed using the method of geometric morphometry. Qualitative histological examination revealed no differences in nerve fibers after intraneurally applied physiological solution and liposomal bupivacaine. Using the method of geometric morphometry, a statistically significant change in the shape of axons was found after intraneurally applied saline solution and liposomal bupivacaine (p=0.0059). No significant differences in histological changes were found after the qualitative histological analysis of nerve fiber cross-section preparations. A statistically significant change in the shape of nerve fiber axons was observed after geometric morphometric analysis of digital images after intraneural application of saline and liposomal bupivacaine.
La forma conservada de todos los componentes de la fibra nerviosa es un requisito previo para la conducción correcta del impulso nervioso. Varios factores pueden cambiar la forma de las fibras nerviosas. En la práctica diaria, el análisis histológico cualitativo es el estándar de oro para detectar cambios de forma. La morfometría geométrica es un método innovador que permite evaluar objetivamente los cambios en la forma de las fibras nerviosas después de la acción de los anestésicos locales. Se utilizó como material un total de sesenta nervios ciáticos, que se inyectaron intraneuralmente con solución salina en el grupo control (n=30), y una solución de bupivacaína liposomal al 1,33 % (n=30) en el grupo de prueba. Después de sacrificados los animales, se tomaron muestras de nervios y se realizaron preparaciones histológicas. Primero se describieron y examinaron las preparaciones utilizando un método histológico cualitativo, después de lo cual se tomaron imágenes digitales. Las imágenes fueron ingresadas al programa MorphoJ y procesadas mediante el método de morfometría geométrica. El examen histológico cualitativo no reveló diferencias en las fibras nerviosas después de la aplicación intraneural de solución fisiológica y bupivacaína liposomal. Usando el método de morfometría geométrica, se encontró un cambio estadísticamente significativo en la forma de los axones después de la aplicación intraneural de solución salina y bupivacaína liposomal (p = 0,0059). No se encontraron diferencias significativas en los cambios histológicos después del análisis histológico cualitativo de las preparaciones de secciones transversales de fibras nerviosas. Se observó un cambio estadísticamente significativo en la forma de los axones de las fibras nerviosas después del análisis de morfometría geométrica de imágenes digitales después de la aplicación intraneural de solución salina y bupivacaína liposomal.

En el presente estudio se evalúa la incorporación de cáscaras de zanahoria como ingrediente en galletas en diferentes concentraciones, de esta manera se pueden disminuir los desperdicios además de aprovechar nutrientes, compuestos bioactivos y fibra dietética de las cáscaras. Se recolectaron cáscaras de zanahorias, se lavaron, deshidrataron a 60°C por 24 horas y posteriormente de molieron finamente para obtener harina de cáscara de zanahoria (HCZ). Se desarrollaron galletas con la incorporación de 0, 5, 10 y 20% de HCZ en reemplazo de harina (Muestras CZ0, CZ5, CZ10 y CZ20 respectivamente). Se evaluó la preferencia y aceptabilidad sensorial de las muestras de galletas, mediante prueba de ordenamiento y escala hedónica de 9 puntos por parámetros (apariencia, color, aroma, sabor, textura, aceptabilidad general) respectivamente. También se evaluó la saciedad producida por su consumo mediante "Cociente de Saciedad" (CS) que utiliza la Escala Visual Análoga (EVA) para cuantificar el estado de saciedad en diferentes tiempos. Se determinó el contenido de fibra dietética (FD) en la HCZ y en las muestras de galletas por método enzimático-gravimétrico. Los resultados demostraron que la muestra CZ20 logró la primera preferencia sensorial y la mayor aceptabilidad sensorial en forma significativa (p<0.05). La incorporación de HCZ en galletas produjo aumento del contenido de fibra dietética y del CS. En base a los resultados obtenidos se concluyó que la mejor opción resultó ser la galleta con 20% de HCZ, ya que sensorialmente es la de mayor preferencia y de mayor aceptabilidad, contiene más fibra dietética y provoca más saciedad.
In the present study, the incorporation of carrot peels as an ingredient in cookies in different concentrations is evaluated, in this way, waste can be reduced in addition to taking advantage of nutrients, bioactive compounds, and dietary fiber from the peels. Carrot peels were collected, washed, dehydrated at 60°C for 24 hours, and then finely ground to obtain carrot peel flour (CPF). Cookies were developed with the incorporation of 0, 5, 10, and 20% of CPF in replacement of flour (Samples CZ0, CZ5, CZ10, and CZ20 respectively). The preference and sensory acceptability of the cookies samples were evaluated using an an-Ranking test and a 9-point Hedonic Scale by parameters (appearance, color, aroma, flavor, texture, general acceptability) respectively. The satiety produced by its consumption was also evaluated through the "Satiety Quotient" (SQ) which uses the Visual Analog Scale (VAS) to quantify the state of satiety at different times. The dietary fiber (DF) content in the CPF and in the cookies samples was determined by the enzymatic-gravimetric method. The results showed that the CZ20 sample achieved the first sensory preference and the highest sensory acceptability in a significant way (p<0.05). The incorporation of CPF in cookies produced an increase in the content of dietary fiber and SQ. Based on the results obtained, it was concluded that the best option turned out to be the cookie with 20% CPF, since sensorially it is the most preferred and most acceptable, contains more dietary fiber and causes more satiety than the other samples.

Introduction: Cerebral Palsy (CP) is characterized by a disorder of posture and movement, commonly leading to disabling orthopedic alterations, including muscle shortening, especially in the lower limbs. Stretching methods, performed gradually, are necessary to delay the impairment in function from muscle shortening. The use of serial casting aims to promote proper alignment, and an ideal and stable support base, in addition to better bone and joint health, leading to better posture, mobility, muscle function, and, subsequently, increased fitness and health.Objective: evaluate range of motion, postural control, and motor performance in children with CP, using serial casting, as well as to measure its effect on fitness through the autonomic nervous system (ANS).Methods: Sixty children and adolescents with CP, of both sexes, 3 to 12 years of age, will be divided into three groups: Groups A, B, and C, with 20 individuals each. Group A will use serial casting, Group B will use the orthosis continuously (with removal only allowed for bathing), and Group C will use the orthosis in their daily routine. Range of motion of the ankle of first and second resistance levels (R1 and R2), gross motor function measure (GMFM), and balance (measured by BERG scale) will be used in the initial and final assessments, and after 6 months and one year of follow-up. Timed-up-and-go (TUG), load distribution (baropodometry), motor performance measured through a real basketball game and the virtual MoveHero game, analysis of body angulation with "mydartfish", and cardiac autonomic modulation through heart rate variability will be assessed in three different situations: barefoot, with orthosis, and with casting.Conclusion: Serial casting demonstrates the potential to produce positive results in the treatment of individuals with CP regarding better alignment, with consequent motor and autonomic improvement.
RESUMEN
INTRODUCTION: Fiber is the initial treatment in chronic functional constipation. However, its role in the group of patients with defecatory dyssynergy is not well established. The objective of the study is to evaluate the efficacy and safety of a high fiber diet in patients with defecatory dyssynergy in the treatment with anorectal biofeedback. PATIENTS AND METHODS: An exploratory, randomized (1:1), double-blind, controlled «add-on¼ clinical trial was carried out in a reference center in Spain in patients with functional constipation and defecatory dyssynergy according to the ROMEIV criteria. CONTROL GROUP: treatment with biofeedback and low-fiber diet (15-20g/day). Experimental group: treatment with biofeedback and high fiber diet (25-30g/day). Analyzed: responder (primary endpoint), patient whose defecatory dyssynergy had been corrected (>20% reduction in anal pressure during the defecation maneuver and normal balloon expulsion test); anorectal parameters (anal relaxation, reduced straining); safety (abdominal symptoms: flatulence, pain, borborygmus, bloating). RESULTS: A total of 44 patients were randomized: 22 per group. The percentage of responders was 75% (15/20; 95%CI: 53 89%) control group and 70% (14/20; 95%CI: 48-85%) experimental group, P=.225. Differences in favor of the control group were only observed in abdominal symptoms: flatulence (P=.028), abdominal distension (P=.041) and digestive comfort (P=.043). CONCLUSIONS: In patients with defecatory dyssynergy, a high-fiber diet not only does not improve the efficacy of anorectal biofeedback but is associated with a loss of improvement in abdominal symptoms.

Background: Apple pomace is a by-product of the fruit juice industry and comprises peel, seed, stem, and pulp tissues. This by-product contains dietary fibers, polyphenols, vitamins, and organic acids that can benefit human health and have a high potential as a dietary source. Baked products are well-known food types to humans and have a key role in feeding people worldwide. Nowadays, enriched products such as bread, cakes, and biscuits are available in stores. Different studies worldwide have been done about applying the by-products of the fruit juice industry in the bakery. Objective: This research aimed to evaluate apple peel (APE) and pulp (APU) powders separately as a partial substitute for wheat flour in cake production. Methods: Apple peel and pulp separately produced as the residual wastes of juicing were dried for 3 hours in oven (60°C). The dried pulp and peel were ground and sieved using a 60 µm mesh. In this research, chemical and physicochemical analyses were performed according to AACC (Approved Methods of the American Association of Cereal Chemists) and standard food analysis methods. Textural characteristic was analyzed by a texture analyzer (Brookfield CT3-10 Kg, US) equipped with an aluminum probe. Results: Different levels of APE and APU powders (10%, 20%, and 30 %) were used to enrich the cakes. The ash content, fat content, water adsorption capacity, and oil absorption capacity of the wheat flour were lower than APU and APE, whereas the moisture content, protein content, bulk density, and pH showed a reverse trend. Adding APU and APP to the cake formula increased total dietary fiber (TDF) from 4.14 % in the control sample to 27.71 % in the sample with 30 % apple peel powder (APE-30). The highest a* colorimetric parameter (redness) in the cake core was 3.82 in the APE-30 sample. The addition of APE and APU significantly increased the hardness, gumminess, and chewiness of the samples (p<0.05). APE-10 samples could improve the nutritional properties of the cakes without significant reduction (p>0.05) in overall acceptance compared to the control sample. Conclusion: The results of this research demonstrated that a partial replacement of the wheat flour with apple pulp and peel significantly increased the dietary fibers, especially insoluble dietary fiber, compared to the control sample. Apple pulp and apple peel powders had the potential for use in cake making as a good source of dietary fibers

Este subproducto contiene fibra dietética, polifenoles, vitaminas y ácidos orgánicos que pueden ser beneficiosos para la salud humana y tienen un alto potencial como fuente dietética. Los productos horneados son de tipos de alimentos bien conocidos para los seres humanos y son clave en la alimentación de las personas de todo el mundo. Hoy en día, los productos enriquecidos como pan, pasteles y galletas están disponibles en las tiendas. Se han hecho diferentes estudios en todo el mundo sobre la aplicación del subproducto de la industria del jugo de frutas en la panadería. Objetivo: El propósito de esta investigación fue evaluar los polvos de cáscara de manzana (APE) y pulpa (APU) como sustituto parcial de la harina de trigo en la producción de pasteles. Métodos: Cáscaras de manzana y pulpa producidas por separado como desechos residuales de jugos, se secaron durante 3 horas en el horno (60 °C). La pulpa seca y la cáscara fueron molidas y tamizadas usando una malla de 60 micras. En esta investigación el análisis químico y físico-químico realizado de acuerdo con el AACC (Aprobado Métodos de la Asociación Americana de Químicos del Cereales) y los métodos estándar de análisis de alimentos. La característica textural fue analizada por el analizador de textura (Brookfield CT3-10 Kg, US) equipado con una sonda de aluminio. Resultados: Se utilizaron diferentes niveles de polvos APE y APU (10, 20 and 30 %) para enriquecer los pasteles. La capacidad de absorción de ceniza, grasa, agua y aceite de la harina de trigo fue menor que la APU y APE, mientras que la humedad, la proteína, la densidad a granel y el pH mostraron una tendencia inversa. Además, APU y APE en fórmula de pastel, aumentaron la fibra dietética total (TDF) de 4.14 % en la muestra de control a 27.71 % en la muestra con un 30 % de polvo de pelar de manzana (APE-30). El parámetro más alto a* colorimétrico en núcleo de pastel fue de 3.82 (enrojecimiento) en la muestra APE-30. La adición de APE y APU aumentó significativamente la dureza, gomosidad y masticabilidad de las muestras (p<0.05). Las muestras de APE-10 podrían mejorar las propiedades nutricionales de los pasteles sin reducción significativa (P<0.05) en aceptación general, en comparación con la muestra de control. Conclusión: Los resultados de este estudio demostraron que un reemplazo parcial de la harina de trigo por pulpa de manzana y cáscara aumentó significativamente la fibra dietética especialmente la insoluble, cuando se compara con la muestra de control. La pulpa en polvo y la cáscara de manzana tienen el potencial de uso en la fabricación de pasteles como una buena fuente de fibra dietética.
