ABSTRACT

Purpose: Hibiscus sabdariffa (HS) extract has several health benefits and anti-obesogenic effects. The aim of the present study was to assess whether the medicinal properties attributable to HS would prevent or mitigate bladder changes induced by obesity in an experimental model. Methods: Forty-eight male Wistar rats were submitted to one of four different dietary interventions (12 animals each): G1, standard diet and water (controls); G2, standard diet and HS tea; G3, a palatable high-fat diet and water; and G4, high-fat diet diet and HS tea. The animals were monitored for body weight, feed, and water and tea intake, according to the allocated group. After 16 weeks, the animals were euthanized, and the levels of creatinine, inflammatory cytokines, testosterone, cholesterol, triglycerides, and electrolytes were evaluated. In addition, histopathological analysis of the animals' bladder was performed. Results: Groups receiving HS (G2 and G4) showed decreased levels of the pro-inflammatory cytokine interleukin-1α. HS tea was able to reduce low-density lipoprotein and triglyceride levels in the G2 group compared to other groups. Only in the G3 there was a significant increase in the body weight when it was compared the 12th and 16th weeks. Leptin was shown to be elevated in the groups that received a high-fat diet. There was a significant decrease in the muscle fibers thickness and in the total collagen count in G4 bladder when compared with G1 and G3. Conclusions: HS has an anti-inflammatory role, can reverse hyperlipidemia in rats, and reduced deleterious effects of obesity on these animals' bladder.

ABSTRACT

INTRODUCCIÓN: El aumento global de la prevalencia de la diabetes ha generado un interés creciente en terapias alternativas, incluyendo el uso de edulcorantes no nutritivos (ENN) en reemplazo de la sacarosa. En el mercado chileno la sucralosa y la estevia son los más utilizados. OBJETIVO: Describir los efectos de la ingesta de estevia y sucralosa sobre los resultados metabólicos y apetito-saciedad en sujetos con diabetes DM1 y DM2, considerando la evidencia disponible. MÉTODOS: Revisión descriptiva. Se realizó búsqueda en PubMed, WoS y Scopus utilizando los siguientes términos y palabras clave: "stevia rebaudiana", "blood glucose", "insulin", "metabolic processes", "sucralose", "diabetes type 1 and 2", "appetite" o "satiety". El análisis de los estudios seleccionados fue discrecional. RESULTADOS: La evidencia sobre la respuesta glicémica e insulínica es variable, con algunos estudios sugiriendo beneficios en la sensibilidad a la insulina y otros reportando efectos nulos. Además, se identificó que los efectos de los ENN en los receptores de sabor dulce y la respuesta hormonal de incretinas, juegan un papel clave en la homeostasis de la glucosa. En cuanto a apetito-saciedad, los ENN podrían no tener el mismo poder saciante que la sacarosa, potencialmente estimulando el apetito y el consumo excesivo. Es fundamental destacar que la heterogeneidad en la metodología de los estudios revisados, en aspectos como el tamaño muestral, la duración, la dosis y la vía de administración de los edulcorantes, dificulta la obtención de conclusiones firmes. CONCLUSIÓN: Aunque la ingestión de estevia y sucralosa ha revelado efectos beneficiosos en el metabolismo glucídico, se subraya la necesidad de llevar a cabo más investigaciones para comprender más a fondo los efectos metabólicos y sobre el apetito-saciedad, especialmente en la población con diabetes adulta y pediátrica.


INTRODUCTION: The global increase in the prevalence of diabetes has sparked a growing interest in alternative therapies, including the use of non-nutritive sweeteners (NNS) as a substitute for sucrose. In the Chilean market, sucralose and stevia are the most widely used. OBJECTIVE: To describe the effects of stevia and sucralose intake on metabolic outcomes and appetite-satiety in individuals with type 1 (DM1) and type 2 (DM2) diabetes, considering the available evidence. METHODS: Descriptive review. A search was conducted on PubMed, WoS, and Scopus using the following terms and keywords: "stevia rebaudiana," "blood glucose," "insulin," "metabolic processes," "sucralose," "diabetes type 1 and 2," "appetite," or "satiety." The analysis of selected studies was discretionary. RESULTS: Evidence regarding glycemic and insulin response is variable, with some studies suggesting benefits in insulin sensitivity and others reporting null effects. Additionally, it was identified that the effects of NNS on sweet taste receptors and the hormonal response of incretins play a key role in glucose homeostasis. Regarding appetite-satiety, NNS may not have the same satiating power as sucrose, potentially stimulating appetite and excessive consumption. It is crucial to highlight that the heterogeneity in the methodology of reviewed studies, including sample size, duration, dose, and route of administration of sweeteners, complicates drawing firm conclusions. CONCLUSION: Although the ingestion of stevia and sucralose has demonstrated beneficial effects on carbohydrate metabolism, there is a pressing need for further research to better understand the metabolic effects and their impact on appetite-satiety, especially in the adult and pediatric diabetic population.

ABSTRACT

Abstract Inborn errors of metabolism are rare disorders with few therapeutic options for their treatments, which can make patients suffer with complications. Therefore, compounded drugs might be a promising option given that they have the ability of meeting the patient's specific needs, (i) identification of the main drugs described in the literature; (ii) proposal of compounding systems and (iii) calculation of the budgetary addition for the inclusion of these drugs into the Brazilian Unified Health System. The research conducted a literature review and used management data as well as data obtained from official Federal District government websites. The study identified 31 drugs for the treatment of inborn errors of metabolism. Fifty eight percent (58%) (18) of the medicines had their current demand identified, which are currently unmet by the local Health System. The estimated budget for the production of compounded drugs was of R$363,16.98 per year for approximately 300 patients. This estimated cost represents a budgetary addition of only 0.17% from the total of expenditures planned for drug acquirement. There is a therapeutic gap for inborn errors of metabolism and compounding pharmacies show potential in ensuring access to medicine therapy with a low-cost investment.

ABSTRACT

O objetivo deste estudo foi compreender como mulheres adultas (acima de 30 anos) diagnosticadas com transtornos alimentares (TAs) vivenciam o adoecer. Trata-se de um estudo qualitativo, descritivo e exploratório, desenvolvido com base no referencial teórico-metodológico da Análise Fenomenológica Interpretativa (AFI). Participaram seis mulheres, com idades entre 34 e 65 anos, atendidas em um serviço especializado. Os dados foram coletados por meio de entrevista aberta, de inspiração fenomenológica, na modalidade remota. As entrevistas foram audiogravadas, transcritas e analisadas seguindo os passos da AFI. Duas categorias temáticas foram identificadas: "Vivendo antes do adoecer" e "Encontrando-se doente." Constatou-se que os sintomas tiveram início anteriormente à vida adulta e que houve dificuldade na confirmação do diagnóstico. Na perspectiva das participantes, conviver com a sintomatologia ficou mais complicado em função de particularidades de manejo dos sintomas na vida adulta, e a idade é percebida como um fator que impacta e dificulta ainda mais a recuperação. As participantes relataram desesperança em relação ao futuro, apesar de a maioria reconhecer melhoras no quadro clínico ao longo do tempo e de valorizar a relação de confiança estabelecida com a equipe multiprofissional.(AU)


This study aimed to understand the experience of illness of adult women (over 30 years) diagnosed with eating disorders (ED). This is a qualitative, descriptive, and exploratory study, using Interpretative Phenomenological Analysis (IPA) as theoretical and methodological framework. A sample of six women aged 34-64 years, assisted in a specialized service, were recruited to complete a phenomenological in-depth open interview. The data were remotely collected. Interviews were audio-recorded, transcribed and analyzed following the IPA. Two thematic categories were identified: "Living before the illness" and "Finding about the illness." It was found that the symptoms started before adulthood and that there was difficulty establishing the diagnosis. Living with the symptoms became more complicated due to particularities of symptom management in adulthood and age is perceived as a factor that impacts recovery and makes it even more difficult. The participants reported hopelessness about the future, although most recognized improvements in the clinical condition over time and valued the trusting relationship they established with the multiprofessional team.(AU)


El objetivo de este estudio fue comprender las experiencias de las mujeres adultas (mayores de 30 años) diagnosticadas con trastornos alimentarios (TA) respecto a la enfermedad. Se trata de un estudio cualitativo, descriptivo y exploratorio, desarrollado a partir del marco teórico y metodológico del Análisis Fenomenológico Interpretativo (AFI). Participaron seis mujeres, con edades de entre 34 y 65 años, atendidas en un servicio especializado. Los datos se recogieron mediante entrevistas abiertas, de inspiración fenomenológica, en la modalidad a distancia. Las entrevistas fueron grabadas en audio, transcritas y analizadas siguiendo los pasos del AFI. Se identificaron dos categorías temáticas: "Vivir antes de enfermar" y "Encontrarse enfermo." Se constató que los síntomas comenzaron antes de la edad adulta y que hubo dificultades de establecer el diagnóstico. La convivencia con síntomas se complicó debido a las particularidades del manejo de los síntomas en la vida adulta y la edad se percibe como un factor que influye y dificulta aún más la recuperación. Los participantes manifestaron desesperanza sobre el futuro, aunque reconocieron mejoras en el cuadro clínico con el paso del tiempo y valoraron la relación de confianza establecida con el equipo multiprofesional.(AU)

ABSTRACT

Mindfulness has been defined as attention and awareness to the present with an attitude of openness, non-judgment, and acceptance. It is suggested that mindfulness can positively influence experiences in sports and physical activity, increasing adherence to these activities. This study aimed to examine new psychometric properties of the State Mindfulness Scale for Physical Activity (SMS-PA) using classical and modern testing theories among Brazilian sport and exercise practitioners. Two studies were conducted. In the first, with 617 Brazilian sports practitioners, confirmatory factor analysis supported the bifactor structure of the SMS-PA composed of two specific (mental and body mindfulness) and one general factor (state mindfulness), which did not vary among genders. The Rasch Rating Scale Model (RSM) supported essential one-dimensionality indicated by the general factor with good item fit statistics (infit/outfit 0.62-1.27). The model presented a good level of Rasch reliability (0.85), and the items difficulty estimation provided an understanding of the continuum represented by their content. In the second study, with 249 Brazilian exercise practitioners, the structural equation modeling showed that Body Mindfulness was associated with positive outcomes (positive affect and satisfaction with practice). The mediation analysis showed that people with higher levels of Body mindfulness tend to experience greater levels of Positive Affect and, consequently, greater Satisfaction with exercises. The results suggest that the Brazilian version of the SMS-PA is an appropriate measure of the state of mindfulness.(AU)


Mindfulness pode ser definido como atenção e consciência no momento presente com uma atitude de abertura, não julgamento e aceitação. A literatura sugere que o mindfulness pode influenciar positivamente experiências no esporte e atividade física e pode exercer um papel na adesão a essas atividades. Este estudo teve como objetivo investigar novas propriedades psicométricas da State Mindulness Sacale for Physical Activity (SMS-PA) utilizando as teorias clássicas e modernas dos testes em praticantes de exercício físico e esporte brasileiros. Dois estudos foram conduzidos. No primeiro, com 617 brasileiros praticantes de esporte, a Análise Fatorial Confirmatória (AFC) demonstrou adequação à estrutura bifatorial da SMS-PA composta por dois fatores específicos (mindfulness mental e físico) e um fator geral (estado de mindfulness), que apresentou invariância entre sexos. A Rasch Rating Scale Model (RSM) corroborou a unidimensionalidade essencial indicada pelo fator geral com bons índices de ajustes (infit/outfit 0.62 -1.27). O modelo apresentou bom nível de precisão Rasch (.85), e a estimação de dificuldade dos itens possibilitou compreensão do continuum representado pelo conteúdo dos itens. No segundo estudo, com 249 brasileiros praticantes de esporte, a Modelagem de Equações Estruturais demonstrou que o mindfulness físico esteve associado a afetos positivos e satisfação com a prática. A análise de mediação mostrou que pessoas com níveis altos de mindfulness físico tendem a apresentar níveis mais elevados de afeto positivo e, consequentemente, níveis mais elevados de satisfação com a prática. Os resultados sugerem que a versão brasileira do SMS-PA é uma medida apropriada do estado de mindfulness para atividades físicas.(AU)


La atención plena puede definirse como la atención y la conciencia en el momento presente con una actitud de apertura, no juicio y aceptación. La literatura sugiere que el mindfulness puede influir positivamente en las experiencias en el deporte y en la actividad física, además de desempeñar un papel en la adherencia a estas actividades. Este estudio tuvo como objetivo investigar nuevas propiedades psicométricas de la State Mindfulness Scale for Physical Activity (SMS-PA) utilizando las teorías clásicas y modernas de las pruebas en practicantes de ejercicio físico y de deporte en Brasil. Para ello, se realizaron dos estudios. En el primer, participaron 617 practicantes de deporte brasileños, y el análisis factorial confirmatorio (AFC) demostró adecuación en la estructura bifactorial de la SMS-PA, compuesta por dos factores específicos (mindfulness mental y físico) y un factor general (estado de mindfulness), que mostró invarianza entre sexos. El Rasch Rating Scale Model (RSM) corroboró la unidimensionalidad esencial indicada por el factor general con buenos índices de ajuste (infit/outfit 0,62-1,27). El modelo mostró un buen nivel de precisión de Rasch (.85), y la estimación de la dificultad de los ítems permitió comprender el continuo representado por el contenido de estos. En el segundo estudio, con 249 practicantes de deporte, el modelo de ecuaciones estructurales mostró que el mindfulness físico estaba asociado a resultados positivos (afecto positivo y satisfacción con la práctica). El análisis de mediación reveló que las personas con altos niveles de mindfulness físico tendían a tener mayores niveles de afecto positivo y, en consecuencia, mayores niveles de satisfacción con la práctica. Los resultados sugieren que la versión brasileña de la SMS-PA es una medida adecuada de mindfulness.(AU)

ABSTRACT

Pouco se sabe sobre a atuação do psicólogo no Brasil junto a pessoas com Diabetes Mellitus. O objetivo desta pesquisa foi identificar os psicólogos brasileiros que trabalham com essa população e suas ações. Foram convidados a responder a um questionário online psicólogos que atuam ou atuaram junto a pessoas com diabetes. Participaram 79 psicólogos, principalmente da região Sudeste (59,5%). Todos declararam que haviam cursado pósgraduação. Na amostra, predominou o gênero feminino (89,9%), com idade entre 26 e 40 anos (46,8%). A maioria dos que atuam com diabetes declarou-se autônoma ou voluntária, e quase metade trabalhava menos do que 10 horas semanais. Entre aqueles que deixaram de trabalhar com diabetes, apenas uma minoria tinha vínculo empregatício. Além do trabalho com pessoas com diabetes, a maior parte declarou exercer outras atividades profissionais, como atendimentos clínicos em consultórios particulares, sugerindo que esta não é a atividade principal. Majoritariamente, os respondentes declararam não ter conhecimentos suficientes para o atendimento específico às pessoas com diabetes. Discute-se a qualidade da formação profissional dos psicólogos no Brasil, a necessidade de aprimoramento em relação à atuação com pessoas com diabetes e as condições de trabalho.(AU)


Little is known about the practice of psychologists in Brazil caring for people with Diabetes Mellitus. The aim of this research was to identify the Brazilian psychologists who work with this population and describe their actions. Psychologists who work or have worked with people diagnosed with diabetes were invited to answer an online questionnaire. The 79 participants lived mainly in the Southeast Region (59.5%). All of them declared to have a graduate degree, most were female (89.9%), aged 26 to 40 years (46.8%). Most of those working with diabetes declared to be autonomous or voluntary, and almost half had a workload of less than 10 hours a week. Among those who stopped working with diabetes, only a minority had a formal employment contract. In addition, most of them stated that they had other professional activities related to clinical care in private offices, suggesting that working with diabetes is not their main activity. Mostly, respondents stated that they did not have enough knowledge to care for people with diabetes. The quality of professional education of psychologists in Brazil, the need for specific improvement in labor relations and conditions were discussed.(AU)

ABSTRACT

Resumen Introducción: Los protistas del género Labyrinthula causan la denominada "Enfermedad del desgaste" en el pasto marino, Thalassia testudinum. Desde el 2008 los monitoreos en el Caribe colombiano han mostrado variación espacial y temporal en la incidencia de la enfermedad, pero sin la alta mortalidad observada en otras regiones del mundo. Objetivo: Analizar algunos parámetros epidemiológicos en T. testudinum y comparar metabolitos entre plantas sanas e infectadas. Métodos: Registramos la severidad, incidencia y prevalencia de esta enfermedad en el Parque Nacional Natural Tayrona e Isla de Providencia, y analizamos muestras de agua y sedimentos. Además, aplicamos cromatografía líquida y de gases, junto con espectrometría de masas, a extractos metanólicos de muestras de hojas y rizomas de brotes sanos e infectados. Resultados: Las praderas se encontraban en buen estado, a pesar de la escasez de brotes de fanerógamas marinas en Tayrona y una alta incidencia (15 %) y severidad (355 %) de la enfermedad en Providencia. Las plantas infectadas tenían niveles más bajos de fenoles, flavonoides y azúcares. Las flavonas sulfatadas con aglicona luteolina y diosmetina, los esteroles (sitosterol y estigmasterol) y las oxilipinas volátiles se acumularon en las hojas (3-hidroxi-2-isopentanona) y los ácidos isopentanoico y octadecatrienoico en los rizomas. Conclusiones: Estos pastos marinos colombianos tienen producción diferencial de metabolitos. Probablemente como una defensa exitosa, aún a niveles bajos de severidad (0.1 %) e incidencia (1 %) de la enfermedad.


Abstract Introduction: Protists of the genus Labyrinthula cause the so-called "Wasting Disease" in seagrass, Thalassia testudinum. Monitoring in the Colombian Caribbean since 2008 has shown spatial and temporal variation in the disease's incidence, but without the high mortality observed in other regions of the world. Objective: To analyze some epidemiological parameters in T. testudinum and to compare metabolites between healthy and infected plants. Methods: We recorded severity, incidence and prevalence of this disease in Tayrona National Natural Park and Providencia Island, and we analyze water and sediment samples. Additionally, we applied gas and liquid chromatography, coupled with mass spectrometry, to methanolic extracts from leaf and rhizome samples of healthy and infected shoots. Results: The meadows were in good condition, despite the scarce seagrass shoots in Tayrona and a high incidence (15 %) and severity (35.5 %) of the disease in Providencia. Infected plants had lower levels of phenols, flavonoids and sugars. Sulphated flavones with aglycone luteolin and diosmetin, sterols (sitosterol and stigmasterol) and volatile oxylipins are accumulated in leaves (3-hydroxy-2-isopentanone) and isopentaenoic and octadecatrienoic acids in rhizomes. Conclusions: These Colombian seagrasses have differential production of metabolites. Probably as a successful defense, even at low levels of severity (0.1 %) and incidence (1 %) of the disease.

ABSTRACT

Mucopolisacaridosis de tipo III es una enfermedad rara, con una incidencia de 1 en 70 000 nacidos vivos, es la más frecuente dentro del grupo de Mucopolisacaridosis y se produce por un defecto en la vía del metabolismo del heparan sulfato. Se caracteriza por afectar a mayor profundidad el sistema nervioso central, el paciente tiene un desarrollo normal hasta aproximadamente los 1 a 3 años de edad y posteriormente empieza con deterioro progresivo, cursa con retraso del desarrollo, alteración del comportamiento y trastorno del sueño agregándose déficit motor y cuadros infecciosos, culminando en un estado de postración. La esperanza de vida oscila entre los 20 a 30 años, aunque depende del fenotipo y la principal causa de muerte fue la neumonía. El diagnóstico definitivo se consigue mediante pruebas genómicas y ensayo enzimático. No cuenta con tratamiento curativo, únicamente con paliación y soporte ante las complicaciones que va desarrollando


Mucopolysaccharidosis III is a rare disease, with an incidence of 1 in 70 000 live births, it is the most frequent within the group of Mucopolysaccharidosis and is caused by a defect in the heparan sulfate metabolism pathway. It is characterized by affecting the central nervous system in greater depth, the patient has a normal development until approximately 1 to 3 years of age and later begins with progressive deterioration, courses with developmental delay, behavioral alteration and sleep disorder, adding motor deficits and infectious pictures, culminating in a state of prostration. Life expectancy ranges from 20 to 30 years, although it depends on the phenotype, and the main cause of death is pneumonia. Definitive diagnosis is achieved by genomic tests and enzymatic assay. It does not have curative treatment, only palliation and support in the face of the complications that it develops.

ABSTRACT

Living at high altitude increases oxidative stress. Likewise, growth and maturation during adolescence can increase levels of reactive oxygen species (ros). Changes in redox profiles have been evaluated in adults living at high altitudes; however, there are no studies on these changes in peripubertal populations living at moderate altitudes, we determine how living at moderate altitude affects the oxidative and inflammatory status of healthy preadolescents and adolescents. Materials and Methods: A cross-sectional study was conducted in healthy male Colombian preadolescents and adoles-cents (9­18 years old, Tanner scale classification) who lived at low altitude (n = 26) or moderate altitude (n = 26). Plasma oxidative and inflammatory status was assessed via spectrophotometry. Oxidative markers included malondialdehyde, 4-hydroxy-trans-2-nonenal, and carbonyl groups. Antioxidant markers included total antioxidant status, glutathione, catalase, superoxide dismutase, uric acid, and thiols. Inflammatory markers included interleukins-1, -6, and -10 and tumor necrosis factor. Results:Only uric acid levels were higher in adolescents (5.34 and 5.66 mg/dl) compared to preadolescents (3.85 and 4.07 mg/dl) in both moderate and low altitude groups, respectively. Participants who lived at mod-erate altitude presented significantly higher levels of malondialdehyde (4.82 and 3.73 nM/mg protein) and lower level of glutathione and thiols (1.21 and 1.26 µmol/mg protein) than in those at low altitude. Their inflammatory profiles did not differ. Conclusion: Oxidant profiles increased in peripubertal popu-lations residing at moderate altitude; this could be owing to antioxidant consumption by ros and active metabolism during puberty.


vivir en altura es un factor que se asocia con el estrés oxidativo. El crecimiento y la maduración pueden ser un estresor adicional. Es insuficiente la evidencia sobre alteraciones del perfil redox en peripúberes residentes a altitudes moderadas. El propósito fue establecer el efecto de vivir en una altitud moderada sobre el perfil redox e inflamatorio en preadolescentes y adolescentes sanos. Materiales y métodos: estudio transversal en varones preadolescentes y adolescentes sanos (9-18 años) que viven en altitud baja (n = 26) o altitud moderada (n = 26). El estado oxidativo plasmático se evaluó mediante espectrofotometría a través de marcadores de oxidación (malondialdehído e hidroxinonenal y grupos carbonilo) y antioxidantes (estado antioxidante total, glutatión, catalasa, superóxido dismutasa, ácido úrico y tioles). El perfil inflamatorio se midió con interleucinas 1, 6, 10 y factor de necrosis tumoral α. Resultados: solo el ácido úrico fue diferente entre adolescentes (5.34 y 5.66 mg/dl para moderada y baja altitud, respectivamente) y preadolescentes (3.85 y 4.07 mg/dl para moderada y baja altitud, res-pectivamente). El grupo de preadolescentes y adolescentes de moderada altitud presentó niveles más altos de malondialdehído (4.82 y 3.73 nM/mg de proteína, respectivamente) y menor glutatión y tioles (1.21 y 1.26 µmol/mg de proteína), en comparación con sus contrapartes de baja altitud. Conclusión: las poblaciones peripúberes que residen en una altitud moderada presentan un perfil oxidante más alto, lo que puede estar relacionado con la depleción de antioxidantes, por una mayor producción de especies reactivas de oxígeno relacionada con la hipoxia y el metabolismo activo de la pubertad.


viver em grandes altitudes é um fator de estresse associado ao estresse oxidativo. Durante a adolescência, os processos de crescimento e maturação podem aumentar as espécies reativas de oxi-gênio. Alterações no perfil redox foram estudadas em adultos expostos a grandes altitudes, mas não em populações peripubertais vivendo em altitudes moderadas. Nosso objetivo é estabelecer o efeito de viver em uma altitude moderada sobre o estado oxidativo e inflamatório em pré-adolescentes e adolescentes saudáveis. Materiais and métodos: foi realizado um estudo transversal em pré-adolescentes e adolescen-tes colombianos saudáveis (9-18 anos, na escala de classificação de Tanner) que viviam em baixa altitude (n = 26) ou altitude moderada (n = 26). O estado oxidativo e inflamatório do plasma foi avaliado por espectrofotometria: 1) Marcadores de oxidação: grupos Malondialdeído + 4-hidroxi-trans-2-nonenal e carbonila; 2) antioxidantes: estado antioxidante total, glutationa, catalase, superóxido dismutase, ácido úrico e tióis; 3) Marcadores de inflamação: interleucinas 1, 6, 10 e fator de necrose tumoral α. Resultados:apenas o ácido úrico foi maior em adolescentes (5,34 e 5,66 mg/dl) em comparação com pré-adolescentes (3,85 e 4,07 mg/dl) dos grupos de altitude moderada e baixa, respectivamente. A altitude moderada apre-sentou níveis significativamente maiores de Malondialdeído (4,82 e 3,73 nM/mg de proteína), e menores níveis de Glutationa e tióis (1,21 e 1,26 µmol/mg de proteína), em comparação com a baixa altitude. Nenhuma diferença foi detectada no perfil inflamatório. Conclusão: as populações peripubertais que residem em altitude moderada apresentam maior perfil oxidante, o que pode estar relacionado ao con-sumo de antioxidantes devido à maior produção de ros relacionada à hipóxia e ao metabolismo ativo por volta da puberdade.

ABSTRACT

Introducción: la fenilcetonuria (PKU) es el error congénito del metabolismo de las proteínas más frecuente. El tratamiento dietético consiste en un plan de alimentación con una ingesta de proteínas naturales restringida, un sustituto proteico libre o de bajo contenido en fenilalanina (Phe) y el aporte de alimentos muy bajos en proteínas. El objetivo principal de este trabajo fue investigar si es posible aumentar la ingesta de proteína natural (PN) que se indica a los pacientes con PKU manteniendo los dosajes de Phe en sangre en rangos de seguridad. Materiales y método: se buscaron en 6 bases de datos electrónicas artículos publicados. Se identificaron un total de 154 artículos de Pub Med por intervalo de años desde 1999 a 2020. Se eligieron 15 artículos que se adaptaron a los criterios de inclusión y exclusión y respondían al objeto de estudio de esta revisión bibliográfica. Resultados: hay varios factores que pueden influenciar la estimación de la tolerancia de Phe como la severidad del fenotipo del paciente, la edad, el rango de seguridad de Phe en sangre, la prescripción de Phe y la adherencia al sustituto proteico. Si los niveles de Phe en sangre se mantienen en forma constante dentro del rango adecuado y por un período determinado, se debería considerar un incremento de la ingesta de Phe. El aumento de la ingesta de PN deberá ser realizado de manera controlada, individual y evaluando en forma constante el impacto en los dosajes de Phe en sangre. Conclusión: optimizar la ingesta de PN ofrece una mejora en la calidad de vida de pacientes con PKU, facilita la capacidad del paciente para socializar y contribuye a una mejor adherencia a la dieta(AU).


Introduction: phenylketonuria (PKU) is the most frequent inborn error of protein metabolism. The dietary treatment consists of a diet with a restricted natural protein intake, a free or low phenylalanine (Phe) protein substitute, and the intake of low protein food. The main objective of this work is to analyze if it is possible to increase the natural protein (NP) intake prescribed to PKU patients while maintaining blood Phe dosages within safe range. Materials and method: studies published were searched in 6 electronic data- basis. A total of 154 Pub Med articles were identified by range of years from 1999 to 2020. Fifteen articles which met the inclusion and exclusion criteria and responded to the objective of this bibliographic review were chosen. Results: several factors may influence Phe tolerance, such as severity of the patient´s phenotype, age, blood Phe safe range, Phe prescription and adherence to protein substitute. If Phe blood levels remain constantly within safe range and for a certain period, an increase of Phe intake should be considered. Increase of NP intake must be carried out in a controlled manner, individually and constantly evaluating blood Phe levels. Conclusion: optimizing NP intake offers the PKU patient an improvement in quality of life, facilitates the patient´s ability to socialize and contributes to a better adherence to the diet(AU).

ABSTRACT

Abstract Changes in metabolite levels of patients using the long-term drug can be comprehensively demonstrated by pharmacometabolomic studies. In this study, biological alterations induced by the administration of solifenacin succinate were investigated with a pharmacometabolomics approach on rat metabolism. Plasma samples obtained from rats were analyzed by LC-Q- TOF/MS/MS. METLIN and HMDB databases were used to identify metabolites. Data were processed and classified with MATLAB 2017b. 53 m/z values were found to be significantly different between the drug and control groups (p ≤ 0.01 and fold analysis > 1.5) and identified by comparing METLIN and HMDB databases. According to multivariate data analysis, changes in arachidonic acid, thromboxane A2, palmitic acid, choline, calcitriol, histamine phosphate, retinyl ester, l-cysteine, l-leucine, beta-alanine, l-histidine levels were found to be statistically significant compare to the control group. Differences in the biosynthesis of phenylalanine, aminoacyl-tRNA, tyrosine, tryptophan, metabolism of glycerophospholipid, cysteine, methionine, histidine, arachidonic metabolism have been successfully demonstrated by the metabolomics approach. Our study provides important information to explain the efficacy and toxicity of chronic administration of solifenacin succinate

ABSTRACT

ABSTRACT Objective: To analyze potential influences of the R/X genetic polymorphism of the ACTN3 gene, as well as of anthropometric and metabolic characteristics on the functional performance of elderly women assisted in primary health care. Method: One hundred and forty-one elderly women were assessed in terms of anthropometric, metabolic and functional aspects, in addition to clinical, cognitive and demographic characteristics. Allele and genotype frequencies of ACTN3 gene polymorphism were determined. Results: 141 elderly women (68.30 ± 6.18 years) were evaluated. No significant differences (p > 0.05) were observed between the RR and RX/XX genotypes in the elderly women's functional performance, anthropometric or metabolic characteristics. The TUG test completion time showed positive correlations with age, body mass index, waist circumference, and fat percentage (s = 0.315; p < 0.001; s = 0.238; p = 0.005; s = 0.174; p = 0.039; s = 0.207; p = 0.014), respectively. Negative correlations were found between the TUG test with absolute handgrip strength (s = - 0.314; p < 0.001) and relative handgrip strength (s = - 0.380; p < 0.001). Conclusion: In our study, there were no influences from ACTN3 gene polymorphisms on the functional performance of the elderly women, which is influenced by other factors.

ABSTRACT

Resumen La obesidad es reconocida como "la gran epidemia" del siglo XXI. Los primeros tratamientos fueron enfocados en el manejo médico, sin lograr los resultados esperados, por lo cual surge la cirugía bariátrica (CB) como la mejor alternativa. Inicialmente la obesidad se concibe como una figura de poder en el imperio egipcio, luego como enfermedad por Galeno e Hipócrates, reapareciendo más tarde como símbolo de fecundidad en Europa. Las primeras técnicas fueron el bypass yeyuno-colónico por Payne y De Wind modificado luego por Scopinaro, consolidándose más tarde como el bypass actual por Mason, Wittgrove e Higa. Por su parte, la gastrectomía en manga fue concebida por Gagner como puente de la derivación biliopancreática, pero dado sus excelentes resultados se consolida como técnica por sí sola. A su vez, la CB evidencia efectos metabólicos inesperados, posicionándose en la actualidad como el mejor tratamiento tanto para la obesidad como para el síndrome metabólico. En Chile la CB se inicia en 1986 con González del Hospital Van Buren con la experiencia en bypass yeyuno-ileal, continuando con Awad y Loehnert del Hospital San Juan de Dios. Luego se consolida con el desarrollo de la CB moderna tanto en la Universidad Católica como en la Universidad de Chile, llegando en la actualidad a ser un procedimiento ampliamente difundido en todo el país. El objetivo principal de la siguiente revisión es analizar el concepto de obesidad en la historia y la evolución de la CB en Chile y el mundo, rememorando sus inicios y destacando su constante desarrollo.


Obesity is recognized as "the great epidemic" of the 21st century. The first treatments were focused on medical management, failing to achieve the expected results, which is why bariatric surgery (BC) emerges as the best alternative. Obesity was initially conceived as a power figure in the Egyptian empire, later as a disease by Galen and Hippocrates, later reappearing as a symbol of fertility in Europe. The first techniques were the jejuno-colonic bypass by Payne and De Wind, later modified by Scopinaro, to finally consolidate as the current bypass by Mason, Wittgrove and Higa. For its part, sleeve gastrectomy was conceived by Gagner as a bridge for biliopancreatic diversion, but given its excellent results, it is consolidated as a technique by itself. In turn, BC shows unexpected metabolic effects, currently positioning itself as the best treatment for both obesity and metabolic syndrome. In Chile, BC started in 1986 with González at the Van Buren Hospital with his experience in jejuno-ileal bypass, continuing with Awad and Loehnert at the San Juan de Dios Hospital. Later, it was consolidated with the development of modern BC both at the Catholic University and at the University of Chile, currently becoming a widely disseminated procedure throughout the country. The main objective of the following review is to analyze the concept of obesity in history and the evolution of BC in Chile and the world, recalling its beginnings and highlighting its continuous development.

ABSTRACT

Resumen Objetivos: Describir las características clínicas y de laboratorio de los pacientes diabéticos tipo 2 (DM2) en tratamiento con fibrina rica en plaquetas (FRP) en el Hospital Clínico Herminda Martín entre los años 2014 y 2016. Materiales y Método: Se revisaron las fichas clínicas de todos los pacientes tratados con FRP en el policlínico de biomateriales en busca de los valores de HbA1c y glicemia, además de otras variables clínicas y de laboratorio que pudieren estar relacionadas con la evolución de las heridas de pie diabético. Se estableció tres grupos de comparación según el tiempo de cicatrización en cicatrización rápida (tiempo percentil 75). Resultados: De un universo de 147 pacientes con DM2 se reportan resultados de 85 (58%). El promedio de edad fue de 61 años, con una glicemia promedio de 243 g/dL y HbA1c de 9,4%. Presentaron un contaje plaquetario dentro de los parámetros normales (promedio 279 plaquetas/mm3). Se encontraron diferencias estadísticas en la escala de valoración de heridas, específicamente en la valoración del puntaje total, así como los parámetros como extensión, profundidad, y dolor entre los grupos de cicatrización rápida y lenta. No se evidenciaron diferencias en el nivel de HbA1c o glicemia en los grupos de cicatrización rápida o lenta, como tampoco en otras variables como edad, creatinina, recuento de plaquetas. Conclusión: No se encontró una asociación entre la velocidad de cicatrización y el nivel de HbA1c en individuos tratados con FRP.


Aims: To describe the clinical and laboratory characteristics of type 2 diabetic patients (DM2) treated with Platelet Rich Fibrin (FRP) at Hospital Clínico Herminda Martín between 2014 and 2016. Materials and Method: Analytical study that includes information from a secondary database. The clinical records of all patients treated with FRP at the Biomaterials Polyclinic were reviewed to search the HbA1c and glycemia values, as well as other clinical and laboratory variables that could be related to the evolution of diabetic foot wounds. Three comparison groups were established according to the healing time in rapid (time 75th percentile). Results: From a universe of 147 patients with DM2, results of 85 (58%) are reported. The average age in the included patients was 61 years. They had an average glycaemia of 243 g/dL, and HbA1c of 9.4%. They presented a platelet count within normal range (average 279 platelets/mm3). Statistical differences between the fast and slow healing groups were found in the wound assessment scale, specifically in the assessment of the total score, extension, depth, and pain. There were no differences in the HbA1c or glycemia level in the fast or slow healing groups, nor in other variables such as age, creatinine, and platelet count. Conclusion: No association was found between healing speed and HbA1c level in individuals treated with FRP.

ABSTRACT

Abstract Introduction: Dental caries is a disease caused by the interaction of several factors, including diet, since the development of the biological environment that promotes cariogenic bacterial metabolism often depends on it. Objectives: To determine the prevalence of caries in preschool children from Huaura, Peru, and to confirm if there is an association between their salivary pH and body mass index (BMI) and the level of knowledge about oral health of one of their parents. Materials and methods: A non-experimental, correlational, and cross-sectional study was conducted in 126 preschoolers equally distributed in 3 age groups (3, 4, and 5 years old). The association between the presence of caries and the variables considered was determined by means of the chi-square test of independence, with a confidence level of 95% and a type I error of 5%. In addition, a multiple logistic regression analysis was performed to calculate the probability of caries development in relation to each risk factor. Results: The prevalence of caries was 80.2% (95%CI:73.2-87.2); furthermore, salivary pH (p=0.012) and the level of parental knowledge (p<0.001) were significantly associated with caries occurrence. Regarding the multiple regression analysis, an OR=0.12 (95%CI:0.02-0.63) was obtained for pH and an OR=0.50 (95%CI:0.35-0.74) for the level of parental knowledge in relation to the probability of caries development. Conclusion: The level of parental knowledge about oral health and high salivary pH levels of preschoolers were protective factors against caries development in the study population. On the other hand, no association was found between BMI and the presence of caries in 5-year-old preschoolers.


Resumen Introducción. La caries dental es una condición causada por la interacción de múltiples factores, entre ellos la dieta, ya que, con frecuencia, de ella depende el desarrollo del medio biológico propicio para el metabolismo bacteriano cariogénico. Objetivo. Determinar la prevalencia de caries en preescolares de Huaura, Perú, y confirmar si hay una asociación con el pH salival y el índice de masa corporal (IMC) de los preescolares, y con el nivel de conocimiento en salud bucal de uno de sus padres. Materiales y métodos. Estudio no experimental, correlacional y transversal realizado en 126 preescolares distribuidos equitativamente en 3 grupos etarios (3, 4 y 5 años). La asociación entre presencia de caries y las variables consideradas se determinó mediante la prueba de independencia de chi cuadrado, con un nivel de confianza del 95% y error tipo I del 5%; además, se realizó un análisis de regresión logística múltiple para calcular la probabilidad de ocurrencia de caries en relación con cada factor de riesgo. Resultados. La prevalencia de caries fue de 80.2% (IC95%:73.2-87.2); además, el pH salival (p=0.012) y el nivel de conocimiento de los padres (p<0.001) se asociaron significativamente con la ocurrencia de caries. En cuanto al análisis de regresión múltiple, se obtuvo un 0R=0.12 (IC95%:0.02-0.63) para el pH y un 0R=0.50 (IC95%:0.35-0.74) para el nivel de conocimiento de los padres en relación con la probabilidad de presentar caries. Conclusión. El nivel de conocimiento sobre salud bucal de los padres y los niveles altos de pH salival de los preescolares fueron factores protectores frente al desarrollo de caries en la población de estudio. Por otra parte, no se encontró asociación entre IMC y presencia de caries en los preescolares de 5 años.

ABSTRACT

Introducción: La variación del magnesio y de indicadores bioquímicos del metabolismo óseo-mineral según la tasa de filtración glomerular en jóvenes sin enfermedad renal es poco conocida por lo que es necesario considerarla para delimitar lo no atribuible a enfermedad renal crónica. El papel que desempeña el magnesio está en estudio. En la enfermedad renal crónica hay una alteración progresiva del metabolismo óseo-mineral que comienza tempranamente. Objetivos: Evaluar valores séricos de magnesio, calcio, fósforo, fosfatasa alcalina y parathormona, excreciones urinarias de 24 h y excreción fraccional de estos electrolitos según categoría G de tasa de filtración glomerular estimada por clearance de creatinina: G1 (normal a alta) y G2 (levemente disminuida) en estudiantes sin enfermedad renal crónica. Material y métodos: Estudio analítico y corte transversal con una muestra de 55 estudiantes voluntarios sin enfermedad renal en el periodo 2018 a 2019. Los analitos se determinaron en suero y algunos en orina de 24 h. Resultados: Solamente magnesio sérico y excreción fraccional de magnesio excreción fraccional de magnesio mostraron diferencias significativas según la categoría G (p < 0,05). Los valores de magnesio sérico magnesio sérico estuvieron dentro de los valores de referencia para el método. En G2, magnesio sérico, descendido respecto a G1 y excreción fraccional de magnesio aumentada, inversamente relacionados. El magnesio sérico disminuyó en promedio 0,26 mg/dL por unidad de aumento de excreción fraccional de magnesio (p = 0,0502). Conclusiones: Se observaron diferencias en magnesio sérico y excreción fraccional de magnesio al comparar los resultados en G1 y G2. Los demás indicadores bioquímicos estudiados no mostraron diferencias por categoría G. Diseños de corte longitudinal en muestras mayores pueden confirmar o no estos hallazgos. Tales estudios pueden aportar a la comprensión de cambios bioquímicos del metabolismo óseo-mineral en etapas iniciales de disminución de la tasa de filtración glomerular(AU)


Introduction: Not much is known about the variation in magnesium and biochemical indicators of the osseous-mineral metabolism according to glomerular filtration rate testing in young people without kidney disease. This variation should therefore be considered to delimit whatever is not attributable to chronic kidney disease. The role played by magnesium is currently under study. In chronic kidney disease a progressive alteration of the osseous-mineral metabolism starts early. Objectives: Evaluate serum values of magnesium, calcium, phosphorus, alkaline phosphatase and parathormone, 24-hour urinary excretion and fractional excretion of these electrolytes according to category G of the glomerular filtration rate estimated by creatinine clearance: G1 (normal to high) and G2 (slightly reduced) in students without chronic kidney disease. Methods: An analytical cross-sectional study was conducted of a sample of 55 student volunteers without kidney disease in the period 2018-2019. The analytes were determined in serum and some in 24-hour urine. Results: Only serum magnesium and magnesium fractional excretion displayed significant differences according to category G (p < 0.05). Serum magnesium values were within the reference values for the method. In G2, serum magnesium was lower than in G1, whereas magnesium fractional excretion was higher, i.e. an inverse relation is observed. Serum magnesium reduction averaged 0.26 mg/dl per unit of magnesium fractional excretion increase (p = 0.0502). Conclusions: Comparison of G1 and G2 results revealed differences in serum magnesium and magnesium fractional excretion. The remaining biochemical indicators studied did not show any differences in category G. Longitudinal studies with larger samples may or may not confirm these findings, thus contributing to a better understanding of the biochemical changes in osseous-mineral metabolism occurring in the initial stages of glomerular filtration rate reduction(AU)

ABSTRACT

O pirarucu, Arapaima gigas é um peixe carnívoro nativo da bacia amazônica. Como peixes carnívoros possuem baixa atividade de amilase, enzimas exógenas melhoram a digestibilidade de carboidratos em rações para aquacultura. O objetivo deste estudo foi avaliar a digestibilidade de níveis crescentes de complexo enzimático em dietas para juvenis de pirarucu (65,2 ± 0,4 g). O desenho experimental foi randomizado com quatro tratamentos [dietas contendo 0,25, 0,50, 0,75 e 1 g kg-1 de complexo enzimático adicionado (Allzyme® SSF®, EUA)] e um controle, com três réplicas com densidade de cinco peixes por unidade e 30 dias de duração. A digestibilidade aparente da matéria seca, proteína bruta e energia bruta foi calculada por quantificação de nutrientes e óxido de cromo nas dietas e fezes. A atividade enzimática, o glicogênio hepático e a proteína total foram determinados a partir de amostras do fígado e intestino anterior. A dieta com 1 g kg-1 de complexo enzimático resultou em um aumento da digestibilidade aparente de proteina bruta, energia bruta, matéria seca, glicogênio hepático e proteínas totais no fígado e intestino, mostrando a eficácia do complexo enzimático na dieta dos pirarucus. A acumulação mais alta de matéria seca, energia bruta e extrato etéreo na carcaça indicou o aumento de peso dos peixes tratados com complexo enzimático. A redução da atividade enzimática endógena (protease, lipase e amilase) sugeriu um aumento da eficácia do processo digestivo. Nossos resultados indicam que a inclusão de 1 g kg-1 do complexo enzimático na dietas de juvenis de pirarucu pode ser recomendada para obter maior digestibilidade de nutientes e performance produtiva.

ABSTRACT

A presente revisão narrativa explora a relação entre exercício físico, nutrição e ritmo circadiano, e os impactos destes na qualidade do sono. O sistema circadiano endógeno, que inclui um "relógio" central e outros periféricos, além dos clock genes, está envolvido na regulação dos comportamentos sono-vigília, bem como nas principais vias metabólicas. Nutrientes também podem influenciar o ritmo circadiano. Observa-se também que o desempenho atlético, tanto nos exercícios de força como nos de endurance, exibe variações no decorrer do dia e da noite. Mais do que isso, o exercício físico parece se mostrar impactante na qualidade do sono. Realizar uma revisão narrativa sobre os trabalhos que relacionam ritmo circadiano, exercício físico e nutrição e os impactos destes na qualidade do sono. revisão da literatura especializada dos últimos dez anos, na qual foram realizadas buscas por artigos científicos selecionados nas principais bases de busca, através dos descritores: sono, crono nutrição, exercício físico. A busca pelos três principais descritores juntos trouxe dois artigos sobre este tema. Uma revisão mostra a relação da ingestão de alimentos com o horário do dia e seu impacto no metabolismo e no ritmo circadiano, bem como os diferentes efeitos do exercício dependente do horário. O outro trabalho mostra o impacto que nutrientes, em especial o triptofano e os carboidratos, e o exercício físico têm sobre o sono. O exercício físico, a nutrição e os hábitos de vida e rotina, interagem com o ritmo circadiano e podem alterar a qualidade do sono


This narrative review explores the relationship among exercise, nutrition and circadian rhythm, and their impact on sleep quality. The endogenous circadian system, which includes a central "clock" and other peripheral ones, in addition to the clock genes, is involved in the regulation of sleep-wake behaviors, as well as in the main metabolic pathways. Nutrients can also influence circadian rhythms. It is also observed that athletic performance, both in strength and endurance exercises, varies throughout the day and night. More than that, physical exercise seems to have an impact on sleep quality. To carry out a narrative review of studies that relate circadian rhythm, physical exercise and nutrition and their impact on sleep quality. Review of the specialized literature of the last ten years, in which searches were conducted for scientific articles selected in the main scientific databases, using the descriptors: sleep, chrono nutrition, physical exercise. The search for the three main descriptors together brought up two articles on this topic. A review shows the relationship of food intake to the time of day and its impact on metabolism and circadian rhythm, as well as the different effects of time of the day-dependent exercise. The other study shows the impact that nutrients, especially tryptophan and carbohydrates, and exercise have on sleep. Physical exercise, nutrition, lifestyle and routine interact with the circadian rhythm and can change sleep quality

ABSTRACT

O objetivo deste estudo foi avaliar o efeito da aplicação de hormônio do crescimento (Growth Hormone - GH) e treinamento de força (TF) na composição do tecido ósseo de ratos Wistar a partir da Espectroscopia Raman. 40 ratos machos foram distribuídos de forma aleatória em quatro grupos: controle (C [n=10]), controle a aplicação de GH (GHC [n=10]), treinamento de força (T [n=10]) e treinamento de força e aplicação de GH (GHT [n=10]). O treinamento foi composto por quatro séries de 10 saltos aquáticos, realizados três vezes por semana, com sobrecarga correspondente a 50% do peso corpóreo e duração de quatro semanas. O GH foi aplicado na dose de 0,2 UI/Kg em cada animal, três vezes por semana e em dias alternados. Ao final do experimento, os animais foram eutanasiados e coletados os fêmures direitos para realização da análise da composição óssea. A espectroscopia Raman (ER) foi utilizada para observar os seguintes compostos a partir de suas respectivas bandas: colágeno e fosfolipídio (1445 cm-1), colesterol (548 cm-1), glicerol (607 cm-1), glicose (913 cm-1), Pico de carboidrato (931 cm-1 ) e prolina (918 cm-1 ). Para a análise estatística, foram realizados os testes de normalidade de Shapiro-Wilk e análise de variâncias ANOVA one-way, seguida pelo pós-teste de Tukey. Os resultados revelaram aumento nas concentrações de colágeno e fosfolipidio, colesterol, glicerol, glicose, pico de carboidrato e prolina em todos os grupos experimentais, associados ou não à realização do ST e/ou aplicação de GH. Porém, somente o grupo T diferiu significativamente do grupo C (p<0,05). Conclui-se que todas intervenções puderam promover ganho no tecido ósseo, porém, somente o grupo T demonstrou diferença significativa nos compostos minerais analisados. (AU)


The objective of this study was to evaluate the effect of the application of growth hormone (GH) and strength training (TF) on the bone tissue composition of Wistar rats using Raman Spectroscopy. 40 male rats were randomly assigned to four groups: control (C [n = 10]), control the application of GH (GHC [n = 10]), strength training (T [n = 10]) and training of strength and application of GH (GHT [n = 10]). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50% of body weight and lasting four weeks. GH was applied at a dose of 0.2 IU / kg to each animal, three times a week and on alternate days. After four weeks, the animals were euthanized and the right femurs were collected to carry out the analysis of the bone composition. Raman spectroscopy (ER) was used to observe the following compounds from their respective bands: collagen and phospholipid (1445 cm-1), cholesterol (548 cm-1), glycerol (607 cm-1), glucose (913 cm-1), Peak carbohydrate (931 cm-1), proline (918 cm-1). For statistical analysis, the Shapiro-Wilk normality tests and ANOVA One-Way analysis of variances were performed, followed by the Tukey post-test. The results revealed an increase in the concentrations of collagen and phospholipid, cholesterol, glycerol, glucose, peak carbohydrate and proline in all experimental groups, associated or not with the performance of ST and / or application of GH. However, only group T differed significantly from group C (p <0.05). It was concluded that all intervention could promote gain in bone tissue, however, only the T group showed a significant difference in the analyzed mineral compounds. (AU)
