Histología testicular y morfología de la vejiga natatoria del pez neotropical Plagioscion magdalenae (Acanthuriformes: Sciaenidae): implicaciones en su taxonomía y distribución / Testicular histology and morphology of the swim bladder of the neotropical fish Plagioscion magdalenae (Acanthuriformes: Sciaenidae): implications in taxonomy and distribution

Introducción: La Pácora (Plagioscion magdalenae) es una especie nativa de Colombia y en categoría de casi amenazada a nivel del país, de la que poco se conoce acerca de las estructuras con aporte etológico en su historia de vida. Objetivo: Analizar el desarrollo gonadal relacionado con la espermatogénesis de P. magdalenae y las implicaciones taxonómicas a partir de la vejiga natatoria. Métodos: Realizamos siete muestreos en dos periodos climáticos: el primero en octubre de 2019 a febrero de 2020 de recolectas bimensuales y la segunda de octubre 2020 a enero 2021 de recolectas mensuales; con el fin de abarcar cada momento del pulso de inundación de la cuenca baja del Magdalena. Describimos la histomorfología testicular y las características macroscópicas de la vejiga natatoria de la especie. Además, analizamos aspectos como relaciones morfométricas, clases de tallas por sexos, la proporción sexual y la época de madurez sexual. Resultados: Analizamos 142 ejemplares y 4 intervalos de tallas fueron establecidos (entre 145 y 575 mm LE), 66 fueron machos y 73 hembras con una proporción sexual global 1.1:0.9 (hembra-macho) sin diferencias. Los machos tienen testículos de tipo tubular, protegidos por el peritoneo que se encuentra recubierto por la musculatura sónica de la vejiga natatoria, la cual posee forma de ''zanahoria'' sin apéndices, con dos bandas laterales de músculos intrínsecos (promedio entre 6.75 cm de largo y 1.48 cm de ancho) unidos por una aponeurosis y que solo se encuentran en machos sexualmente maduros. Conclusión: Los testículos poseen una organización de tipo lobular irrestricto y la espermatogénesis se da en lóbulos seminíferos. La vejiga natatoria de la Pácora es simple y no tiene estructuras accesorias. La distribución geográfica de P. magdalenae se restringe a la cuenca del río Magdalena en Colombia.

Introduction: The Pácora (Plagioscion magdalenae) is a species native to Colombia and in near-threatened category at the country level, of which little is known about the structures with ethological contribution in its life history. Objective: To analyze the gonadal development related to spermatogenesis of P. magdalenae and the taxonomic implications from the swim bladder. Methods: We collected seven samples in two climatic periods: the first from October 2019 to February 2020 of bimonthly collections, and the second from October 2020 to January 2021 of monthly collections; to cover every moment of the flood pulse of the lower Magdalena basin. We described the testicular histomorphology and macroscopic characteristics of the swim bladder of the species. In addition, we analyzed aspects such as morphometric relationships, size classes by sex, sex ratio and time of sexual maturity. Results: We analyzed 142 specimens and established 4 size intervals (between 145 and 575 mm SL), 66 were males and 73 females with an overall sex ratio of 1.1:0.9 (female-male) with no differences. Males have tubular testes protected by the peritoneum covered by the sonic musculature of the swim bladder, which has a ''carrot'' shape without appendages, with two lateral bands of intrinsic muscles (average between 6.75 cm long and 1.48 cm wide) connected by an aponeurosis and found only in sexually mature males. Conclusion: The testes have an unrestricted lobular organization and spermatogenesis occurs in the seminiferous lobes. The swim bladder of the Pácora is simple and has no accessory structures. The geographic distribution of P. magdalenae is restricted to the Magdalena River basin in Colombia.

Variación Morfológica en la Musculatura Cefálica de Diplobatis ommata y Narcine vermiculatus (Chondrychthyes: Narcinidae) / Morphological Variation in the Cephalic Musculature of Diplobatis ommata and Narcine vermiculatus (Chondrychthyes: Narcinidae)

Los trabajos realizados sobre batoideos han demostrado que existen grandes variaciones en la musculatura de la región cefálica ventral, estos cambios están asociados a los diferentes estilos de vida de los organismos y por tanto, a los mecanismos de alimentación. El objetivo de este trabajo fue llevar a cabo un estudio comparativo de la morfología de la musculatura cefálica dorsal y ventral de dos especies de la familia Narcinidae: Narcine vermiculatus y Diplobatis ommata. Se observó que ambas especies comparten un patrón morfológico común. Los músculos que mostraron mayores variaciones en la región dorsal fueron el depresor rostral, el preorbital lateral y el elevador rostral. La diferencia más importante en esta región, entre ambas especies, fue la ausencia del músculo cucularis en D. ommata. En la región ventral las principales diferencias se observaron en los músculos depresor mandibular, preorbital medial, interbranquial y depresor hiomandibular. Este último músculo está formado por dos paquetes en D. ommata, en tanto que en N. vermiculatus por uno. Se puede concluir que la morfología de la musculatura cefálica es constante; sin embargo, se observan diferencias importantes en el grado de desarrollo de los músculos tanto en la región dorsal como en la ventral.

SUMMARY: Works conducted on batoids have revealed large variations in the musculature of the ventral cephalic region, associated to the different lifestyles of these organisms and, therefore, to their feeding mechanisms. This work aimed to conduct a comparative study of the dorsal and ventral cephalic muscular morphology of two species of the family Narcinidae: Narcine vermiculatus and Diplobatis ommata. It was observed that both species share a common morphological pattern. Muscles with larger variations in the dorsal region were the rostral depressor, the lateral preorbital and the rostral elevator. The most relevant difference in this region between both species was the absence of the cucularis muscle in D. ommata. In the ventral region, the main differences were observed in the mandibular depressor, medial preorbital, interbranchial and hyomandibular depressor muscles. In D. ommata, the latter is formed by two packages, and by one in N. vermiculatus. It can be concluded that the cephalic musculature is constant; however, significant differences are observed in the muscle development degree in both the dorsal and the ventral regions.

Effects of disordered eating behaviors and sedentary lifestyle prevention program in male and female Mexican adolescents / Efectos de un programa de prevención de conductas alimentarias de riesgo y sedentarismo en adolescentes mexicanos, hombres y mujeres

Abstract Introduction Adolescents are the group with the highest risk of developing disordered eating behaviors (DEB). Preventing this problem is of the utmost importance due to the physical and psychological consequences. Objective To evaluate the effects of a universal prevention program for disordered eating behaviors (DEB), thin ideal internalization (TII), drive for muscularity (DM), and sedentary lifestyle among Mexican adolescents. Method A quasi-experimental study with repeated measures (pre-test, post-test, six-month, and one-year follow-up) was carried out in a non-probabilistic sample of 523 adolescents (46.7% of females) aged 15-19 years (Mage = 16.07). We worked in two private high schools, one of them was designed as control group (CG), and the other as intervention group (IG). For both, female and male adolescents', data were collected using the Brief Questionnaire for Disordered Eating Behaviors (BQDEB) and the short form of the International Physical Activity Questionnaire (IPAQ). To evaluate TII the Attitudes toward Body Figure Questionnaire was applied in females, while in males Drive for Muscularity Scale (DMS) was used. Results After one-year, repeated measures analyses of variance (ANOVAs) revealed a significant reduction of the mean DEBs scores both in female (p = .01) and male (p = .03) adolescents of the IG with respect to CG. In IG, females decreased significantly the mean TII score as well as the mean DM score in males. Physical Activity increased in IG females from pre-test to posttest; however, the effect was not maintained over time. Discussion and conclusion These findings have important implications for future interventions with Mexican adolescents. We must take sex differences into account to choose activities and strategies that will enhance the effects of the program.

Resumen Introducción Los adolescentes constituyen el grupo con mayor riesgo de desarrollar conductas alimentarias de riesgo (CAR). Prevenirlas es de suma importancia debido a las consecuencias físicas y psicosociales. Objetivo Evaluar los efectos de un programa de prevención universal en conductas alimentarias de riesgo (CAR), interiorización del ideal de delgadez (IID), obsesión por la musculatura (OM) y sedentarismo en adolescentes mexicanos. Método Estudio cuasi-experimental con medidas repetidas (pre-test, post-test, seguimiento a seis meses y un año) en una muestra no probabilística de 523 adolescentes (46.7% mujeres) de 15-19 años de edad (Medad = 16.07). Se trabajó en dos escuelas preparatorias privadas, una como grupo control (GC) y otra como grupo intervenido (GI). Para mujeres y hombres, los datos se recolectaron usando el Cuestionario Breve para Conductas Alimentarias de Riesgo (CBCAR) y la versión corta del Cuestionario Internacional de Actividad Física (IPAQ). Para evaluar el IID en mujeres, se utilizó el Cuestionario de Actitudes hacia la Figura Corporal (CAFC) y en hombres la Escala para Obsesión por la Musculatura (DMS). Resultados Después de un año, el ANOVA de medidas repetidas mostró una reducción significativa en la media de CAR, tanto en mujeres (p = .01) como en hombres (p = .03) del GI respecto al GC. En el GI, la media de IID en mujeres disminuyó significativamente, así como la media de OM en hombres. La actividad física aumentó en las mujeres del GI desde el pre-test hasta el post-test; sin embargo, el efecto no se mantuvo en el tiempo. Discusión y conclusión Estos hallazgos tienen implicaciones para futuras intervenciones con adolescentes mexicanos. Se deben tomar en cuenta las diferencias por sexo para elegir las actividades y las estrategias que potenciarían los efectos del programa.

Tratamiento no farmacológico y su acción sobre la musculatura esquelética en ancianos con sarcopenia / Non pharmacological treatment and its action on the skeletal musculature of elderly with sarcopenia

La sarcopenia es un síndrome geriátrico caracterizado por la pérdida generalizada y progresiva de la masa muscular esquelética, así como disminución de la fuerza muscular y del rendimiento físico. Al respecto, el tratamiento no farmacológico es de gran importancia por su acción en la musculatura esquelética. En este trabajo se precisan los elementos fundamentales para aplicar esta terapia en ancianos, cuya evaluación clínica incluye, entre otros, la valoración de comorbilidades crónicas y agudas y de su funcionalidad física mediante el índice de Katz y la escala de Lawton y Brody, el volumen de actividad física planificada y el diagnóstico de los estadios de sarcopenia por el estado de la masa muscular esquelética, según el European Working Group on Sarcopenia in Older People. También se proponen programas de ejercicios de fuerza y resistencia corroborados en metaanálisis, con una duración, frecuencia e intensidad establecidas, para fortalecer la musculatura esquelética y su acción sobre los cambios fisiopatológicos, a fin de lograr la adaptación muscular y mejorar la funcionalidad física; con ello, se previenen las caídas y fracturas en los ancianos con sarcopenia y se mejora su calidad de vida.

Sarcopenia is a geriatric syndrome characterized by the widespread and progressive loss of the skeletal muscular mass and decrease of the muscular force and physical performance. In this respect, the non-pharmacological treatment is of great importance due to its action in the skeletal musculature. In this work the fundamental elements to apply this therapy in elderly are specified whose clinical evaluation includes, among others, the valuation of chronic and acute comorbidities and of their physical functionality by means of the Katz index and the Lawton and Brody scale, the volume of planned physical activity and the diagnosis of the sarcopenia phases by the condition of the skeletal muscular mass, according to the European Working Group on Sarcopenia in Older People. Programs of force and resistance exercises corroborated in meta-analysis are also suggested, with an established duration, frequency and intensity, to strengthen the skeletal musculature and its action on the pathophysiological changes, in order to achieve the muscular adaptation and improve the physical functionality; with it, falls and fractures are prevented in the elderly with sarcopenia and improve their life quality.

Obsesión por la delgadez y la musculatura en mujeres, un estudio transcultural: Comparación entre Chile y España

RESUMEN Es cada vez más frecuente la exposición de los adultos emergentes a prácticas socioculturales que afectan su salud mental, cumpliendo un papel importante en la manifestación de la obsesión por la delgadez y la musculatura. Por ello, el propósito del estudio fue comparar la obsesión por la delgadez y la musculatura entre mujeres adultas emergentes universitarias de Chile y España respecto a factores socio-culturales, satisfacción corporal y variables psicológicas vinculadas a la imagen corporal. De esta forma, la presente investigación se realizó desde un enfoque cuantitativo, con un diseño no experimental transversal, de alcance correlacional, con una muestra compuesta por 230 participantes (n chilenas= 155; n españolas= 75). Los resultados evidenciaron una diferencia significativa entre ambos grupos en la obsesión por la musculatura, siendo mayor en España. El modelo predictivo de obsesión por la delgadez estuvo compuesto por las variables de perfeccionismo, satisfacción corporal en forma negativa, presión social de la familia, de los medios de comunicación y nacionalidad española, explicando así el 45% de la varianza, mientras que el modelo explicativo para obsesión por la musculatura permite predecir un 16% de su varianza a partir de la nacionalidad española, la obsesión por la delgadez, la presión social de la familia y la actividad física regular. Finalmente, se plantea la necesidad de fomentar indagaciones futuras y profundizar más en las temáticas que permitan prevenir en las jóvenes mujeres con mayor riesgo de padecer alguna de estas problemáticas.

ABSTRACT Exposure of emerging adults to sociocultural practices that affect their mental health is more and more frequent, playing an important role in the manifestation of a drive for thinness and muscularity. The purpose of the study was to compare the drive for thinness and drive for muscularity, among emerging adult university women from Chile and Spain. We evaluated socio-cultural factors, body satisfaction and psychological variables linked to body image using a quantitative approach, with a non-experimental cross-sectional design. We used a correlational-causal scope, with a sample of 230 participants (n Chileans= 155; n Spanish= 75). The results evidenced a significant difference between the two groups in drive for muscularity, being higher in Spain. The predictive model of drive for thinness was made up of the variables of perfectionism, negative body satisfaction, social pressure from the family, the media and Spanish nationality, explaining 45% of the variance. The model for drive for muscularity predicted 16% of the variance based on Spanish nationality, drive for thinness, social pressure from the family and regular physical activity. Finally, there is a need to encourage future inquiries and delve deeper into the issues that allow young women at higher risk of suffering from any of these problems to be prevented.

Manifestaciones pulmonares y sistémicas de la hipertensión arterial pulmonar: Un enfoque panvascular

La hipertensión arterial pulmonar (HAP) es una grave enfermedad cuyo resultado final de la interacción entre el tono vascular y la alteración progresiva de la remodelación de las arterias pulmonares provoca insuficiencia cardíaca derecha y muerte. El remodelado vascular pulmonar es la alteración estructural clave en la hipertensión pulmonar. Este proceso implica cambios en la íntima, media, adventicia y espacio perivascular, a menudo con la interacción de células inflamatorias. Los mecanismos fisiopatológicos de la HAP abarcan una serie de modificaciones vasculares que producen un aumento de la resistencia vascular pulmonar. Las modificaciones vasculares que se producen en la HAP incluyen: la vasoconstricción, la proliferación del músculo liso, la inflamación, la apoptosis endotelial, la proliferación endotelial resistente a la apoptosis, la fibrosis, la trombosis in-situ, y finalmente, las lesiones plexiformes. Hasta hace poco, la HAP se consideraba una enfermedad restringida a la circulación pulmonar. Sin embargo, existe una creciente evidencia de que los pacientes con HAP también exhiben disfunción vascular sistémica, como lo demuestra la alteración de la dilatación mediada por el flujo de la arteria braquial, el flujo sanguíneo cerebral anormal, la miopatía esquelética y la enfermedad renal intrínseca. Los datos recientes apoyan un vínculo con los eventos genéticos y moleculares detrás de la patogénesis de la HAP. Esta revisión sirve de introducción a los principales hallazgos sistémicos en la HAP y la evidencia que apoya un vínculo común con la fisiopatología de la HAP. Sobre la base de la evidencia disponible, proponemos un paradigma en el que las anomalías metabólicas, la lesión genética y la disfunción vascular sistémica contribuyen a las manifestaciones sistémicas de la HAP. Este concepto no sólo abre interesantes posibilidades de investigación, sino que también anima a considerar las manifestaciones extrapulmonares en el tratamiento de los pacientes con HAP, pues la disfunción vascular sistémica contribuiría a las manifestaciones sistémicas de la HAP.

Pulmonary arterial hypertension (PAH) is a serious disease whose end result of the interaction between vascular tone and the progressive alteration of the remodeling of the pulmonary arteries causes right heart failure and death. Pulmonary vascular remodeling is the key structural alteration in pulmonary hypertension. This process involves changes in the intima, media, adventitia, and perivascular space, often with the interaction of inflammatory cells. The pathophysiological mechanisms of PAH include a series of vascular modifications that produce an increase in pulmonary vascular resistance. Vascular modifications that occur in PAH include: vasoconstriction, proliferation of smooth muscle, inflammation, Endothelial apoptosis, apoptosis-resistant endothelial proliferation, fibrosis, in-situ thrombosis, and finally, plexiform lesions. Until recently, PAH was considered a disease restricted to the pulmonary circulation. However, there is growing evidence that patients with PAH also exhibit systemic vascular dysfunction, as evidenced by impaired brachial artery flow-mediated dilation, abnormal cerebral blood flow, skeletal myopathy, and intrinsic kidney disease. Recent data support a link to the genetic and molecular events behind the pathogenesis of PAH. This review serves as an introduction to the main systemic findings in PAH and the evidence supporting a common link with the pathophysiology of PAH. Based on the available evidence, we propose a paradigm in which metabolic abnormalities, genetic injury, and systemic vascular dysfunction contribute to the systemic manifestations of PAH. This concept not only opens up interesting research possibilities, but also encourages consideration of extrapulmonary manifestations in the treatment of patients with PAH, since systemic vascular dysfunction would contribute to the systemic manifestations of PAH.

A hipertensão arterial pulmonar (HAP) é uma doença grave cujo resultado final da interação entre o tônus vascular e a alteração progressiva da remodelação das artérias pulmonares causa insuficiência cardíaca direita e morte. A remodelação vascular pulmonar é a principal alteração estrutural na hipertensão pulmonar. Esse processo envolve mudanças na íntima, média, adventícia e espaço perivascular, muitas vezes com a interação de células inflamatórias. Os mecanismos fisiopatológicos da HAP incluem uma série de modificações vasculares que produzem um aumento na resistência vascular pulmonar. As modificações vasculares que ocorrem na HAP incluem: vasoconstrição, proliferação do músculo liso, inflamação, apoptose endotelial, proliferação endotelial resistente à apoptose, fibrose, trombose in situ e, finalmente, lesões plexiformes. Até recentemente, a HAP era considerada uma doença restrita à circulação pulmonar. No entanto, há evidências crescentes de que os pacientes com HAP também apresentam disfunção vascular sistêmica, conforme evidenciado pela dilatação prejudicada mediada pelo fluxo da artéria braquial, fluxo sanguíneo cerebral anormal, miopatia esquelética e doença renal intrínseca. Dados recentes suportam uma ligação com os eventos genéticos e moleculares por trás da patogênese da HAP. Esta revisão serve como uma introdução aos principais achados sistêmicos em HAP e as evidências que apoiam uma ligação comum com a fisiopatologia da HAP. Com base nas evidências disponíveis, propomos um paradigma em que anormalidades metabólicas, lesão genética e disfunção vascular sistêmica contribuem para as manifestações sistêmicas da HAP. Esse conceito não apenas abre possibilidades interessantes de pesquisa, mas também incentiva a consideração das manifestações extrapulmonares no tratamento de pacientes com HAP, uma vez que a disfunção vascular sistêmica contribuiria para as manifestações sistêmicas da HAP.

Centesimal composition and meat yield of Hoplias malabaricus: association with intestinal parasites / Composição centesimal e rendimento da carne de Hoplias malabaricus: associação com parasitos intestinais

Abstract Hoplias malabaricus is a non-migratory fish commonly found in the Mogi Guaçu River basin, mainly feeding on fish, small crustaceans and insects. It forms part of the diet for humans, birds and some mammals. This fish has great nutritional value, with both good quality and good quantities of essential vitamins and amino acids. Regarding parasitic fauna, this fish can host different species of helminths in its gastrointestinal tract. The aim of the present study was to investigate the possible interference of parasitism in the meat yield from H. malabaricus and the centesimal composition. For this purpose, fish specimens were collected from marginal lagoons of the Mogi Guaçu River (Pirassununga, state of São Paulo, Brazil) using hooks and fishing nets. We found that all specimens of H. malabaricus were parasitized by at least one species, including larvae of Contracaecum sp. (Nematoda: Anisakidae). Parasitism did not have any significant influence on centesimal composition, but meat yield was negatively correlated with the abundance of larvae.

Resumo Hoplias malabaricus é um peixe comumente encontrado na bacia do rio Mogi Guaçu. Não realiza migração e alimenta-se de peixes, pequenos crustáceos e insetos. Faz parte da dieta de seres humanos, aves e outros mamíferos piscívoros. Apresenta grande valor nutricional em relação à quantidade e à qualidade de vitaminas e aminoácidos essenciais. Em relação à fauna parasitária, este peixe pode albergar diferentes espécies de helmintos em seu trato gastrointestinal. O presente estudo teve como objetivo verificar a eventual interferência do parasitismo no rendimento e na composição centesimal da carne do pescado de H. malabaricus. Para isso, foram realizadas coletas por um ano, em lagoas marginais do rio Mogi Guaçu, Pirassununga, estado de São Paulo, Brasil, utilizando-se anzol e rede de espera. Como resultado, todos os exemplares de H. malabaricus estavam parasitados por, pelo menos, uma espécie de parasita, prevalecendo larvas de Contracaecum sp. (Nematoda: Anisakidae). O parasitismo não afetou a composição centesimal da carne do peixe, mas foi encontrada uma correlação negativa forte entre o rendimento da carne e o número de larvas de parasitos.

Evaluation of the applicability of musculoskeletal ultrasonography of the thoracolumbar and lumbar spine segment of healthy dogs / Avaliação da aplicabilidade da ultrassonografia musculoesquelética do segmento toracolombar e lombar da coluna vertebral de cães hígidos

Changes in the spine of dogs are usually detected in clinical and in surgical practice. Few studies exist on musculoskeletal ultrasound anatomy of the thoracolumbar and lumbar segments of the normal spine of dogs. This study aimed to compare the normal musculoskeletal ultrasound anatomy of the T10-S1 vertebral segments with images obtained with magnetic resonance imaging (MRI), computed tomography (CT), and anatomical structures, and to establish the ability to identify structures using these modalities. Ultrasound scans allowed visualization of the muscles of the region, articular processes, spinous process, interspinous ligament, and yellow ligament in the lumbosacral window. Computed tomography images provided better bone details, compared to ultrasound images. Low-field MRI allowed the identification of the same structures identified with ultrasound imaging, and allowed the identification of cerebrospinal fluid, transverse processes, and provided improved detail of the intervertebral discs and spinal cord. Knowledge of ultrasound anatomy of the region may allow the the identification of muscle and ligament injuries. Thus, in cities where CT and MRI are inaccessible, ultrasonography of the region could be a good alternative to identify possible changes not observable with radiographic examination or to complement radiographic examination.(AU)

Alterações na coluna vertebral de cães são comumente encontradas na rotina clínica e cirúrgica veterinária. Existem poucos estudos sobre a anatomia ultrassonográfica musculoesquelética do segmento toracolombar e lombar da coluna vertebral normal de cães. O objetivo deste trabalho foi comparar a anatomia ultrassonográfica musculoesquelética normal dos segmentos vertebrais T10-S1 com imagens obtidas pela ressonância magnética, tomografia computadorizada e peças anatômicas visando demonstrar a sua capacidade de identificação de estruturas. A varredura ultrassonográfica permitiu a visibilização da musculatura da região, processos articulares, processos espinhosos, ligamentos interespinhosos e ligamento amarelo na janela lombossacra. A tomografia computadorizada forneceu imagens com melhor detalhamento ósseo quando comparada ao exame ultrassonográfico. A ressonância magnética de baixo campo permitiu a identificação das mesmas estruturas que o exame ultrassonográfico acrescido da identificação do líquido cerebroespinal, processos transversos e melhor detalhamento dos discos intervertebrais e medula espinhal. Com o conhecimento da anatomia ultrassonográfica da região, acredita-se que lesões musculares e ligamentares possam ser identificadas. Vale salientar que em cidades onde a tomografia computadorizada e a ressonância magnética não estejam acessíveis a ultrassonografia da região pode ser uma boa alternativa para identificar possíveis alterações não visibilizadas ao exame radiográfico, ou complementá-lo.(AU)

Equilíbrio corporal, mobilidade e força muscular respiratória de idosas praticantes do método Pilates / Body balance, mobility and respiratory muscle strength in elderly women practitioners of the method Pilates

Introdução: O Método Pilates é baseado em movimentos do corpo inteiro, respiração, concentração, centralização, precisão e ritmo. Não está claro se a prática desta atividade é superior à manutenção de um estilo de vida ativo. Objetivo: Comparar o equilíbrio corporal, a mobilidade e a força muscular respiratória de mulheres idosas praticantes do Método Pilates e idosas ativas. Métodos: Estudo transversal analítico em 22 idosas, sendo 11 praticantes do Método Pilates (PMP) e 11 idosas ativas (IA). As participantes foram classificadas pelo Perfil de Atividade Humana (PAH) e avaliadas por Timed up and Go (TUG), Escala de Equilíbrio de Berg (EEB) e manovacuometria. Resultados: A idade da amostra foi de 69,36 ± 9,49 anos. A média no TUG das PMP foi de 8,06 ± 4,29 segundos, e das IA de 8,28 ± 2,82 (p>0,05). Na EEB, a média do escore pelas PMP foi 54,63 ± 1,91 e pelas IA foi 52,90 ± 4,01 (p>0,05). Quanto à avaliação da força muscular respiratória, também não houve diferença significativa entre os grupos, mas houve diferença nas IA ao comparar os valores reais (PiMáx = 59,00 cmH2O e PeMáx = 54,00 cmH2O), com os preditivos (PiMáx = 77,12 cmH2O e PeMáx = 74,18 cmH2O), com p<0,05. Conclusão: Manter-se fisicamente ativa ou praticar o Método Pilates parece ter o mesmo efeito sobre o equilíbrio corporal e a mobilidade de mulheres idosas, principalmente entre os 60 e 65 anos. No entanto, idosas que praticam Pilates parecem manter a força muscular respiratória mais adequada à sua idade. (AU)

Introduction: The Pilates Method is based on whole body movements, breathing, concentration, centering, precision and rhythm. It is not clear whether the practice of this activity is superior to maintain an active lifestyle. Objective: To compare the body balance, mobility and respiratory muscle strength of elderly women practicing the Pilates Method and active elderly women. Methods: An analytical cross-sectional study was carried out on 22 elderly women, including 11 Pilates Method Practitioners (PMP) and 11 Active Elderly (AE) women. Participants were classified by the Human Activity Profile (HAP) and evaluated by Timed up and Go (TUG), Berg Balance Scale (BBS) and manovacuometry. Results: The sample was 69.36 ± 9.49 years old. The TUG mean of the PMPs was 8.06 ± 4.29 seconds, and of the AE was 8.28 ± 2.82 (p> 0.05). In BBS, the mean of the PMP score was 54.63 ± 1.91 and the AE was 52.90 ± 4.01 (p> 0.05). Regarding the evaluation of respiratory muscle strength, there was also no significant difference between the groups, but there was a difference in AE when comparing the actual values (PiMax = 59.00 cmH2O and PeMax = 54.00 cmH2O), with the predictive values (PiMax = 77 , 12 cmH 2 O and Pemax = 74.18 cmH 2 O), with p <0.05. Conclusion: Staying physically active or practicing the Pilates Method seems to have the same effect on the body balance and mobility of older women, especially between 60 and 65 years. However, elderly women who practice Pilates seem to maintain respiratory muscle strength more appropriate to their age. (AU)

Relationships between residual feed intake and feedlot performance, profitability, and carcass traits in Brahman cattle / Relações entre consumo alimentar residual e desempenho em confinamento, lucratividade e características de carcaça de bovinos da raça Brahman

The present study aimed to evaluate the feedlot performance, profitability and carcass traits of Brahman bulls classified according to the residual feed intake (RFI). Twenty-four bulls (19-month old, 370±34kg live weight) were housed in individual pens for 54 days and had the daily feed intake (observed dry matter intake, DMIobs; DMI % live weight, LW) and average daily gain (ADG) measured. Ultrasound carcass evaluations were performed at the initial and final weighings, when measurements were taken of Longissimus dorsi area, ratio, Longissimus and Biceps femoris fat thickness. The animals were ranked and divided into high (>+0.5 standard deviation; SD), medium (between ±0.5 SD from the mean), and low (<-0.5 SD) RFI groups. Low-RFI animals had lower DMIobs (P<0.10) and DMI % LW (P<0.05). No significant differences in initial and final weight or ADG were noticed (P>0.05). Low-RFI animals showed lower weight gain cost and higher daily profit (P<0.05). Carcass traits were similar between groups, regardless of evaluation date (P>0.05). Selection for RFI lead to animals with lower feed intake without affecting weight gain or carcass traits, thereby providing increased profitability for beef cattle farming.(AU)

Objetivou-se avaliar o desempenho, o lucro e as características de carcaça de tourinhos Brahman classificados de acordo com o consumo alimentar residual (CAR). Vinte e quatro tourinhos (19 meses de idade e 370±34kg de peso vivo) foram alojados em baias individuais por 54 dias para avaliação do consumo de alimentos (CMSobs; CMS % peso vivo, PV) e ganho de peso diário (GMD). Avaliações de carcaça por ultrassonografia foram realizadas nas pesagens inicial e final, com mensurações da área do Longissimus dorsi, ratio, espessura de gordura sobre o Longissimus e sobre o Biceps femoris. Os animais foram ranqueados e divididos em grupos de alto (>+0,5 desvio-padrão; DP), médio (entre ±0,5 DP da média) e baixo (<-0,5 DP) CAR. Animais de baixo CAR apresentaram menor CMSobs (P<0,10) e menor CMS % PV (P<0,05). Não houve diferença nos pesos inicial e final e GMD (P>0,05). Animais de baixo CAR apresentaram menor custo do ganho de peso e maior lucro diário (P<0,05). As características de carcaça foram semelhantes entre os grupos independentemente da data de avaliação (P>0,05). A seleção para CAR leva a animais de menor consumo, sem afetar o ganho de peso e as características de carcaça, fornecendo maior lucro para a atividade pecuária.(AU)

Cumplimiento de analgesia peridural solicitada versus administrada en partos vaginales, durante el periodo 2014-2016 en el Hospital Hernán Henriquez Aravena / Compliance with epidural analgesia requested versus administered in vaginal deliveries, during the period 2014-2016 at the Hospital Hernán Henriquez Aravena

INTRODUCCIÓN: El dolor que se asocia al trabajo de parto (TDP) afecta a todas las mujeres y puede producir alteraciones tanto maternas como fetales, e incluso interferir con el desarrollo normal del proceso. OBJETIVO: Conocer el grado de cumplimiento de solicitud de analgesia peridural en partos vaginales en el servicio de preparto del Hospital Hernán Henríquez Aravena (HHHA) versus la analgesia administrada. MATERIAL Y MÉTODO: Estudio descriptivo retrospectivo, realizado en base a datos del sistema perinatal del servicio de Ginecología y Obstetricia del HHHA, periodo 2014-2016. RESULTADOS: Del total de partos Vaginales entre los años 2014-2016 solo se solicitó Analgesia Peridural en 56.5% de ellos. De las analgesias solicitadas en éste período se administraron un 98%. CONCLUSIÓN: Basado en los registros clínicos, el grado de cumplimiento es cercano al 100% en las analgesias solicitadas. Se observó un incremento anual entre 2014 y 2016 de solicitud de anestesia en procedimientos de parto, y a pesar de esto la eficiencia del hospital no se ha visto afectada. No obstante, se espera que el porcentaje de solicitudes siga en aumento manteniendo el alto nivel de eficiencia.

INTRODUCTION: Pain associated with labor affects all women and can cause both maternal and fetal alterations and even interfere with the normal development of the process. Objective: to know the degree of compliance with the request for epidural analgesia in vaginal deliveries versus the analgesia administered at the Hernán Henríquez Aravena Hospital (HHHA). Method: Retrospective descriptive study, based on data from the perinatal system of the HHHA Gynecology and Obstetrics Service, period 2014-2016. Results: Of the total number of Vaginal births between 2014-2016 only 56.5% of them were requested for epidural analgesia. Of the analgesia requested in this period, 98% were administered. Conclusion: Based on the clinical records, the degree of compliance is close to 100% in the requested analgesia. There was an annual increase between 2014 and 2016 in the application of anesthesia in childbirth procedures, and despite this, hospital efficiency has not been affected. However, the percentage of applications is expected to continue to increase while maintaining the high level of efficiency. It is pertinent to propose studies to extrapolate this result at regional and national levels.

Fortalecimiento de la musculatura del piso pélvico en gestantes en control en un centro de salud familiar: un estudio experimental / Strengthening of the pelvic floor muscles in control pregnant women in a family health center: an experimental study

ANTECEDENTES: Aunque la presencia de disfunciones del piso pélvico es más prevalente en mujeres adultas de avanzada edad, durante el embarazo o post parto se puede presentar incontinencia urinaria (IU), siendo la de esfuerzo (IUE) la más común en este período. OBJETIVO: Evaluar el efecto del entrenamiento de la musculatura del piso pélvico (EMPP) en gestantes controladas en el Centro de Salud Familiar de la comuna de Yerbas Buenas, durante el año 2016. MATERIAL Y MÉTODO: Estudio piloto cuasi-experimental en gestantes entre 20 y 40 anos, atendidas en Atención Primaria de Salud. Muestra piloto: 20 gestantes (20 a 28 semanas de gestación). Se les evaluó la fuerza de la musculatura pélvica (FMP) mediante Escala de Oxford Modificada al inicio y luego de 8 semanas de EMPP, además se midieron las características socio-bio-demográficas, antecedentes mórbidos y obstétricos, hábitos y la sintomatología urinaria, lo que fue medido utilizando el International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF). RESULTADOS: El 50% de las gestantes refirió IU durante el embarazo, siendo en el 95% IUE. No se relacionó la paridad, tipo de parto y EN con menor FMP. El EMPP mejoró significativamente la FMP de las gestantes (p<0,05) CONCLUSIONES: La IUE fue la DPP más prevalente en las gestantes. Es posible mejorar la FMP en gestantes con el EMPP, por tanto, se debería considerar su incorporación a las prestaciones del sistema público de salud como una acción de promoción de la salud sexual y reproductiva, ya que es una intervención de bajo costo y baja complejidad.

BACKGROUND: Although pelvic floor dysfunctions are more prevalent in older adult women, urinary incontinence may be present during pregnancy or postpartum, with stress incontinence (SUI) being the most common in this period. OBJECTIVE: To evaluate the effect of pelvic floor muscle training on pregnant women attended in a family health center in Yerbas Buenas, Chile, in 2016. MATERIAL AND METHOD: Pilot quasi-experimental study in pregnant women, aged between 20 and 40, attending a primary health care center. Pilot sample: 20 pregnant women (20 to 28 weeks). Pelvic muscle strength was assessed by Modified Oxford Scale at the beginning of the study and then after 8 weeks of exercising. Socio-and bio-demographic characteristics, morbidity and obstetric history, habits, and urinary symptoms were assessed using the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF). RESULTS: 50% of the women presented urinary incontinence during pregnancy, with 95% of them suffering from stress incontinence. Parity, type of delivery and nutritional status did not relate to lower pelvic musculature strength. Pelvic floor muscle training significantly improved the women's pelvic muscle strength (p <0.05). CONCLUSIONS: Stress urinary incontinence was the most prevalent pelvic floor dysfunction in pregnant women. It is possible to improve pelvic muscle strength in pregnant women through pelvic floor muscle training; therefore, their inclusion into the public health system should be considered as an action to promote sexual and reproductive health, since it is a low-cost and low-complexity intervention.

Muscular anatomy of the pectoral girdle and forelimb of Iguana i. iguana (Squamata: Iguanidae) / Anatomia muscular do cíngulo peitoral e membro torácico de Iguana i. iguana (Squamata: Iguanidae)

Green iguana has arboreal and terrestrial habits. It is widely distributed in Central and South America, inhabiting several biomes in Brazil. Some researches were focused on this species, however, morphological information are still limited. With that in sight, we aimed to add data to the anatomical knowledge. Two post mortem specimen of Iguana i. iguana were acquired, donated by a scientific breeding, and dissected. To describe the muscles we refuted the skin and removed the fascias, individualizing the muscles. We identified the following muscles: pectoralis, deltoideus clavicularis, deltoideus scapularis, trapezius, latissimus dorsi, coracobrachialis brevis, coracobrachialis longus, serratus thoracis, levator scapulae, biceps brachii and triceps brachii. Some of them, like coracobrachialis brevis, present conservative anatomy, originating from the ventral surface of the coracoid and inserting onto the proximal humerus. Some, like trapezius and biceps brachii, are similar to other reptile species, trapezius takes its origin from the thoracodorsal fascia and biceps arises by two heads and inserts on the radial tuberosity. Deltoideus clavicularis and deltoideus scapularis share a common insertion tendon. Pectoralis varies its origin and divisions, however, the insertion always occur on the deltopectoral crest. Triceps brachii is comprised of four heads. Its long medial head originates via a tendinous arc, feature described only in crocodilians. We conclude that Iguana i. iguana forelimb musculature is similar to other reptiles, presenting its own characteristics that reflect its habits.

Iguanas verdes tem hábitos arbóreos, terrestres e aquáticos, e são totalmente herbívoras. Tem ampla distribuição na América Central e do Sul, habitando vários biomas no Brasil. Investigações diversas tiveram esta espécie como foco, embora informações morfológicas sejam ainda escassas. Objetivando adicionar dados ao conhecimento anatômico, dois espécimes de Iguana i. iguana foram obtidos post mortem, por doação de um criadouro científico, e dissecados. Os músculos foram individualizados para identificação e descrição das origens, inserções e características. Alguns músculos, como o coracobraquial curto, apresentam morfologia conservativa, sua origem ocorre na superfície ventral do coracóide e inserção na epífise proximal do úmero. O trapézio, o bíceps braquial e o deltóide clavicular se apresentam similares à outros répteis, com a origem do trapézio na fáscia toracodorsal e o bíceps, com duas cabeças, se inserindo no tubérculo do rádio. O deltóide clavicular possui o tendão de inserção unido ao do músculo deltóide escapular. O músculo peitoral apresenta variações em sua origem e divisões, mas a inserção sempre ocorre na crista deltopeitoral. A origem da cabeça longa caudal do tríceps ocorre por meio de arco tendíneo, característica antes descrita apenas em crocodilianos. A musculatura de Iguana i. iguana se apresenta similar à de outros répteis no geral, com características próprias refletindo seus hábitos.

Una opción para restaurar la musculatura intrínseca cubital cuando el nervio interóseo anterior no se encuentra disponible / An option to restore ulnar intrinsic muscles when the anterior interosseus nerve is not available

Resumen: Antecedentes: Las lesiones de nervio periférico, principalmente las traumáticas, tienen efectos devastadores para la función. Tradicionalmente las opciones eran en forma temprana el injerto nervioso y en forma tardía la transferencia tendinosa. Durante los últimos años se han venido realizando transferencias nerviosas cuando la lesión es temprana y la placa motora aún es viable. Los resultados en su mayoría son superiores a los injertos nerviosos y a las transferencias tendinosas. Métodos y resultados: Se presenta el caso de una paciente que sufrió lesión de nervio mediano y cubital en el antebrazo y se utilizaron las ramas redundantes de los músculos extensor carpi ulnaris y extensor digiti quinti. Los resultados fueron buenos a los cuatro años. Conclusión: Cuando existe un déficit de la musculatura intrínseca cubital de la mano, el donador favorito es la rama terminal del nervio interóseo anterior. Cuando éste no se encuentra, debemos tener opciones para restaurar esta función.

Abstract: Background: The peripheral nerve injuries are devastating for the patient; the classic reconstructive options are the Nerve Graft and Tendon Transfers. Lately the Nerve Transfers are being used more and more broadly. They are an excellent option on early injuries and when the motor plate is still alive. The advantages are numerous, because the functional recovery is much better. Methods and results: We report the case of a patient who sustained and injury on the median and ulnar nerve, so the EDQ and ECU branches were used to restore the Ulnar Intrinsic Function. The 4-year follow-up showed good results. Conclusion: The ulnar intrinsic innervations provide dexterity; fine motor function and pinch, which is essential for a functioning hand. The most popular donor to restore the function of the motor branch of the ulnar nerve is the anterior interosseous nerve. When this is unavailable the use of the redundant branches of the EDQ and ECU must be considered.

THE MANDIBULAR MUSCLES OF Puma concolor (MAMMALIA, CARNIVORA, FELIDAE) / Músculos mandibulares de Puma concolor (Mammalia, Carnivora, Felidae)

This manuscript describes the mandibular muscles of the puma (Puma concolor), a widely sparse American carnivorous mammal. The muscles on the right and left side of the head of three specimens -two adult males and one young female- were dissected and photographed. This study increases our knowledge on the mandibular soft tissue and adds important anatomical information to the poorly known and documented musculature of this felid, the largest of the subfamily Felinae.

En este trabajo se describen los músculos mandibulares del puma (Puma concolor), un mamífero carnívoro de amplia distribución en América. Se diseccionaron y fotografiaron los músculos izquierdos y derechos de la cabeza de tres individuos, dos machos adultos y una hembra juvenil. Este estudio incrementa nuestro conocimiento de los tejidos blandos mandibulares y por lo tanto, aporta información anatómica valiosa de la escasamente conocida y documentada musculatura de este félido, el más grande de la subfamilia Felinae.

Morphological study of the iris musculature in diurnal and nocturnal raptors / Estudio morfológico de la musculatura del diafragma en aves rapaces diurnas y nocturnas

In literature it is established that the iris musculature consists of striate muscle fibers in birds while in mammals it consists of smooth muscles. Some authors report the presence of smooth muscle tissue also in the iris of some species of birds. In the present study we report on the iris muscle tissues (type of tissue, direction and mean diameter of muscle fibers or cells) in five species of Accipitriformes (diurnal raptors) and four species of Strigiformes (nocturnal raptors) because they show different way of life depending of their predatory behavior. This morphological study was carried out from raptors died or euthanized at the Wild Life Rescue Centre of Sea and Water birds in Livorno (Italy). From histological examination of iris serial radial sections we find both striated and smooth musculature even if with marked differences among analyzed species, not directly correlated with diurnal or nocturnal lifestyle. Striated fibers are always present, mainly with cross direction, throughout the iris stroma, while the histological differences concern the smooth cells. Indeed, harrier and sparrow hawk (Accipitriformes) and great horned owl and little owl (Strigiformes) show a compact layer of cross smooth muscle cells throughout the iris stroma. In the other species analyzed smooth muscle cells are slightly detectable as scattered or not detectable. Since the cross smooth muscle tissue allows to maintain a myotic state for extended periods of time, our results might be correlated more to the predatory behavior than the taxonomic order.

En la literatura, se establece que la musculatura del iris se compone de fibras musculares estriadas en las aves, mientras que en los mamíferos, la forman los músculos lisos. Algunos autores informan también de la presencia de tejido muscular liso en el iris de algunas especies de aves. El presente estudio informa sobre los tejidos musculares del iris (tipo de tejido, la dirección y diámetro de las fibras musculares o células) en cinco especies de Accipitriformes y cuatro especies de Strigiformes que muestran diferentes hábitos en función de su comportamiento depredador. Este estudio morfológico se realizó en aves rapaces que murieron o fueron eutanasiadas en el Centro de Vida Salvaje de Rescate de Aves Marinas y Acuáticas de Livorno (Italia). El examen histológico de secciones seriadas radiales del iris mostró la presencia tanto de musculatura estriada como lisa, aunque con marcadas diferencias entre las especies analizadas, pero sin correlación directa con el estilo de vida diurna o nocturna. Las fibras estriadas estuvieron siempre presentes, principalmente en dirección transversal a lo largo del estroma del iris, mientras que las diferencias histológicas fueron de las células lisas. Tanto el aguilucho y el gavilán (Accipitriformes) como el buho real y el mochuelo (Strigiformes) mostraron una capa compacta de células musculares lisas transversales en todo el estroma del iris. En las otras especies analizadas, las células musculares lisas fueron ligeramente detectables de manera dispersa o no detectables. Dado que el tejido del músculo liso transversal permite mantener un estado miótico durante largos períodos de tiempo, nuestros resultados podrían estar más correlacionados con el comportamiento depredador, y no con el orden taxonómico.

Compared morphology of the cephalic musculature in five species of genus Urotrygon (Chondrichthyes: Urolophidae) / Morfología comparada de la musculatura cefálica de cinco especies del género Urotrygon (Chondrichthyes: Urolophidae)

This work aims to describe the morphology of dorsal and ventral cephalic musculature in five species of genus Urotrygon. Muscular differences were observed, mainly in the development level. Muscles showing certain degree of variation in the dorsal region were the cucullaris and the ethmoideo-parethmoidalis. In ventral view, higher variation was observed. Muscles showing differences were the depressor rostri, the depressor hyomandibularis, the preorbitalis medial, the coracohioideus, and the depressor mandibularis. Urotrygon aspidurus was the species with the largest differences, as it has no mandibular depressor, and the rostral depressor is quite developed. The shape and arrangement of cephalic musculature in Urotrygon is similar to that reported for genus Urolophus and Dasyatis, however, it is different from that of most specialized myliobatoids.

El presente trabajo tiene por objetivo describir la morfología de la musculatura cefálica dorsal y ventral de cinco especies del género Urotrygon. En los músculos de la región cefálica dorsal y ventral se observaron diferencias, principalmente en el grado de desarrollo. Los músculos que mostraron cierto grado de variación en la región dorsal fueron el cucularis y el etmoideo paraetmoidal. En vista ventral los músculos que mostraron diferencias fueron el depresor rostral, el depresor hiomandibular, el preorbitalis medial, el coracohioideus y el depresor mandibular. Urotrygon aspidurus fue la especie que mostró mayores diferencias ya que no presenta el músculo depresor mandibular, y el depresor rostral está muy desarrollado. La forma y disposición de la musculatura cefálica de Urotrygon es similar a la reportada para especies de los géneros Urolophus y Dasyatis, sin embargo, es diferente a la de los miliobatoideos más especializados.

Bases ósseas e musculares do corte comercial de pescoço de jacaré-do-pantanal (Caimanyacare Daudin, 1802) / Bone and muscular bases of commercial cut from the neck of Yacare Caiman (Caiman yacare Daudin, 1802)

O jacaré-do-pantanal (Caiman yacare) é uma espécie abundante no ecossistema do Pantanal. Sua exploração comercial está regulamentada desde 1990 e se tornou um agronegócio em expansão. Para atender essa demanda, uma unidade processadora instalada em Mato Grosso, vem comercializando carne de jacaré em diferentes cortes, entre os quais o filé de dorso, oriundo do pescoço, nos últimos quatro anos. O objetivo desta pesquisa foi descrever os músculos e correspondentes bases ósseas desse corte. Para a descrição de ossos, utilizaram-se seis carcaças desossadas de exemplares juvenis de jacaré-do-pantanal, além de um exemplar adulto obtido após morte do animal, por doação, do Zoológico da UFMT. Os ossos foram macerados em água corrente, clareados com solução de água oxigenada a 10 volumes, e seus detalhes anatômicos foram descritos. Para descrever o músculo, 24 exemplares juvenis foram obtidos após abate e esfola, conservados em freezer e descongelados quando utilizados, sem qualquer fixação. Após a evisceração, foram dissecados em ambos os antímeros, para verificação de simetria de ocorrência, fixações musculares, relacões de sintopia, forma e arquitetura muscular. Verificou-se que a coluna cervical em C. yacare apresenta nove vértebras cervicais (VC), associadas com as respectivas costelas, que servem de base principal ao filé de dorso, que é constituído pela musculatura cervical, exceto os músculos intertransversais cervicais e intercostais cervicais externos.

The yacare Caiman (Caiman yacare) is an abundant species in the Pantanal ecosystem. Commercial exploitation was regulated in 1990 and has become a thriving business. In order to fulfill this demand, a processing plant settled in Mato Grosso state, Brazil, has been supplying for the last four years different cuts of Pantanal Caiman meat, including the "filé de dorso" (back sirloin) obtained from the neck. The aim of this study was to describe the muscles and corresponding bones related to this cut. To describe the bones, we used six boned carcasses from juvenile yacare Caiman, as well as an adult specimen obtained after animal death, by donation from the Federal University of Mato Grosso Zoo. The bones were macerated in water, bleached with 10 volume-hydrogen-peroxide solution, and their anatomical details were recorded. In order to describe the muscles, 24 juvenile specimens were obtained after slaughter and skinning, preserved in a freezer at -20oC, and thawed at the time of use, without any fixation. After evisceration, the specimens were dissected on both sides to verify symmetry of structures, muscle attachments, sintopy relations, shape, and muscular architecture. The cervical spine of C. yacare features nine cervical vertebrae (CV) associated to their ribs, serving as the main base for the back sirloin cut, which is formed by neck muscles, except for the intertransverse cervical and external intercostal cervical muscles.

Síndrome de Prune Belly: Diagnóstico y manejo

El síndrome de Eagle-Barret o síndrome de Prune Belly también conocido como "síndrome de abdomen en ciruela pasa", es un cuadro cuya etiología aún se desconoce. Se caracteriza por la de ciencia de la musculatura de la pared abdominal, dilatación del tracto urinario y criptorquidia bilateral. La incidencia estimada es de 1 en 35,000 a 1 en 50,000 recién nacidos vivos, ocurriendo aproximadamente más del 95% de los casos en masculinos. Las manifestaciones clínicas de la triada de anormalidades presentes en esta entidad, van desde el defecto muscular presente en la pared abdominal, que consta solamente de piel y peritoneo, razón por la cual el tejido dérmico presenta una serie de estriaciones, que permiten la palpación fácil de las vísceras, asociándose además una alteración del sistema urogenital que se caracteriza por la dilatación de la vejiga como consecuencia de una obstrucción distal, con reflujo vesico-ureteral. Se describe un neonato con Síndrome de abdomen en ciruela pasa, de sexo masculino, nacido de 40 semanas de gestación y pesó 3 050 g al nacer. El examen clínico mostró un neonato con un abdomen globuloso, con redundancia de la piel que huelga a los costados rebosantes, la palpación del abdomen no descubre la tonalidad muscular. No se palpa visceromegalia y hay presencia normal de ruidos hidroaéreos. El examen físico del tórax y cardiovascular no reportó datos patológicos. Examen neurológico normal. La ecografía renal mostró alteraciones en el tracto urinario. Revela además criptorquidia bilateral. Este caso destaca la importancia del diagnóstico temprano y el manejo adecuado del paciente tanto a nivel primario como en el tercer nivel de atención; ya que si ofrecemos el manejo adecuado podemos brindarle a este tipo de pacientes un mejor pronóstico de vida.

Eagle-Barrett syndrome, formerly known as prune-belly syndrome, it's a disease whose etiology is still unknown. It's characterized by deficiency of abdominal wall musculature,a dilated urinary tract,and bilateral cryptorchidism. The estimated incidence is 1 in 35,000 to 1 in 50,000 live births, with more than 95% of cases occurring in males. Clinical manifestations of the triad of abnormalities present in this entity, ranging from muscle defect present in the abdominal wall, consisting only of skin and peritoneum, reason why the dermal tissue presents a series of striations, allowing easy palpation of the viscera, further associating an alteration of the urogenital system characterized by the expanded bladder following a distal obstruction, with vesicoureteral reflux. We report the case of a male neonate born after 40 weeks of gestation with a body weight of 3 050 g with Prune Belly syndrome. The physical examination revealed a distended abdomen with redundant skin that wrinkle like a prune, no visceromegaly was found and normal abdominal sounds were heard. The examination of thorax and cardiovascular systems were normal. The neurologic exam was normal. A renal ultrasound revealed alteration of the urogenital system. Bilateral cryptorchidism was also observed. This case highlights the importance of early diagnosis andappropriatemanagement both in primary health as tertiary,because if we bring the adequate treatment we will be able to o er to this patients a better life prognosis.

Interiorización de ideales estéticos y preocupación corporal en hombres y mujeres usuarios de gimnasio / Internalization of aesthetic ideals and body concern in males and females gym users

Este estudio exploró la interiorización del modelo estético corporal de delgadez y la preocupación por la musculatura y por la delgadez entre cuatro grupos: dos de hombres y dos de mujeres (usuarios y no usuarios de gimnasio). Particularmente, se examinó la presencia de sintomatología de dismorfia muscular en los cuatro grupos; se comparó la preocupación por la delgadez, por la musculatura y la interiorización del ideal de delgadez entre los grupos; y se analizó la relación entre las variables para cada grupo. Participaron 467 hombres y mujeres (169 usuarios de gimnasio y 298 no usuarios de gimnasio) de 13 a 53 años de edad, quienes completaron tres medidas: Cuestionario de Influencias del Modelo Estético Corporal, Cuestionario de Imagen Corporal y Escala de Motivación por la Musculatura. La presencia de sintomatología de dismorfia muscular en varones usuarios de gimnasio fue de 15%, y menor de 3% en mujeres usuarias de gimnasio y participantes no usuarios de gimnasio de ambos sexos. Las usuarias de gimnasio puntuaron más alto en el Cuestionario de Imagen Corporal en comparación con los hombres y se observó una asociación positiva y significativa entre la interiorización de ideales corporales y la preocupación por la delgadez y por la musculatura. La relación entre el Cuestionario de Imagen Corporal y la Escala de Motivación por la Musculatura puede interpretarse como el deseo que existe en los dos grupos de hombres y en el grupo de mujeres usuarias de gimnasio, de tener ambas, musculatura y poca grasa en el cuerpo; las dos vías conducen a la práctica de conductas alimentarias no saludables.

This study explored the internalization of thinness aesthetic body model, and the muscularity and thinness concern, in four groups: two of men and two of women (gym and non-gym users). Specifically, it was explored the presence of symptoms of muscle dysmorphia in four groups, the muscularity -and body shape concern and internalization of thin ideals in the four groups were compared, and the relationship between variables for each group was analyzed. The sample included 467 men and women (169 gym users and 299 non-gym users) from 13 to 53 years-old, who completed three measures: The Influence of the Body Shape Model Questionnaire, the Body Shape Questionnaire, and the Drive for Muscularity Scale. The presence of symptoms of muscle dysmorphia in males gym users was 15% and lower than 3% in women gym users, as well as in -males and females non-gym users. The women gym users scored higher in the Body Shape Questionnaire compared to the men, and a positive and significant association was observed between the internalization of the body ideals, the thinness concern, and drive for muscularity. The relationship between Body Shape Questionnaire and Drive for Muscularity Scale can be interpreted as the desire in both groups of men and in the gym-users women to have both, muscularity and leanness in body; both ways lead to the practice of unhealthy eating behaviors.
