Introducción: la resolutividad del primer nivel de atención (PNA) es una cualidad fundamental de los sistemas de salud porque repercute en el funcionamiento de los otros niveles y en los servicios de urgencia. En nuestro país se ha insistido sobre la necesidad de contar con un PNA resolutivo, sustentado en la sobrecarga asistencial que soportan los servicios del segundo nivel de atención (SNA) y las puertas de emergencia de los hospitales o sanatorios, atribuida, entre otros aspectos, a la baja resolutividad del PNA. Objetivos: evaluar las consultas que requirieron traslado a los servicios de emergencia de la Administración de los Servicios de Salud del Estado (ASSE) o de la Corporación Médica de Paysandú (COMEPA), y las referencias realizadas a especialistas del SNA por la Unidad Docente - Asistencial (UDA) N°74 de Paysandú durante 2014. Método: estudio observacional, descriptivo y de corte realizado en cinco servicios del PNA de Paysandú, usando instrumentos de registro específicos. Resultados: de un total de 8.265 consultas realizadas,75 requirieron traslado al servicio de emergencia (0,9%), predominando en adultos jóvenes, en meses de junio y setiembre, debido principalmente a patologías respiratorias, y requiriendo ambulancia en el 49% de los casos. El 5% (n=415) del total de consultas realizadas fueron derivadas al SNA, predominando en adultos mayores de 45 años, y debido a patologías de ojos y anexos, aparato circulatorio y locomotor. Conclusiones: la resolutividad de la UDA de Medicina Familiar y Comunitaria de Paysandú es alta; se valora especialmente las competencias de dicha disciplina en ese sentido, y es posible mejorarla dotando de mayores recursos materiales al PNA (por ejemplo, oftalmoscopio).

Introduction: Alterations in the musculoskeletal system, especially in the lower limbs, limit physical activity and affect balance and walking. Postural impairments in haemophilic preteens could increase the risk of bleeding events and deteriorate the physical condition, promoting the progression of haemophilic arthropathy. Aim: This study aims to evaluate static postural balance in haemophilic children, assessed by means of the Wii Balance Board® (WBB). Methods: Nineteen children with haemophilia and 19 without haemophilia aged 9-10 years, have participated in this study. Postural balance was assessed by performing four tests, each one lasting 15 s: bipodal eyes open (BEO), bipodal eyes closed (BEC), monopodal dominant leg (MD) and monopodal non-dominant leg (MND). Two balance indices, standard deviation of amplitude (SDA) and standard deviation of velocity (SDV) were calculated in the anterior-posterior (AP) and medial-lateral (ML) directions. Results: Index values were higher in haemophilic group and the differences were statistically significant (P < 0.05) in only six (SDAAP in BEO, BEC and MD conditions, SDAML in BEO, SDVAP in BEO and SDVML in MND condition) of 16 parameters analysed. Conclusion: Tests performed indicate a poorer static postural balance in the haemophilic cohort compared to the control group. Accordingly, physiotherapy programmes, physical activity and sports should be designed to improve the postural balance with the aim of preventing joint deterioration and improving quality of life. © 2016 John Wiley & Sons Ltd.

O turismo é um fenômeno cuja importância vem crescendo no mundo contemporâneo. Devido ao seu caráter transversal e complexo, são múltiplos os desafios para o gerenciamento de suas atividades setoriais. Partindo dessas premissas, este artigo analisa de que forma a estrutura organizacional do turismo, da maneira como está configurada, dificulta a sua gestão no caso do estado de Sergipe. Para tanto, utilizou-se pesquisa documental e entrevistas com técnicos e gerentes das três unidades administrativas que compõem o aparato institucional de gestão do turismo. Os resultados revelaram que a estrutura organizacional prejudica a gestão do turismo na medida em que há sobreposições de função tanto intra quanto interorganizacionais, baixa institucionalização dos processos de planejamento, desenvolvimento e marketing turísticos, pouca articulação entre os órgãos.

Num sistema de ensino cada vez mais exigente, a experimentação assume um papel fundamental na aquisição e validação do conhecimento. No ensino da Física, a necessidade de compreender a influência do meio num dado conceito teórico leva a que a experimentação tenha um carácter obrigatório. Neste contexto, surgem três cenários capazes de suportar a aprendizagem dos conceitos teóricos adquiridos. A simulação que faz uso da velocidade e capacidades de cálculo do computador para obter o resultado de uma experiência, a experimentação tradicional em laboratório, na qual o aluno executa, presencialmente, a sua experiência e por último a experimentação remota, que permite a execução de uma experiência real sem a presença física do aluno. Esta dissertação apresenta o projeto de um aparato para experimentação remota do “Lançamento de projéteis”. De forma a providenciar um meio de ensino de Física mais flexível, o aparato desenvolvido permite, aos alunos, a determinação da aceleração da gravidade e o estudo da dependência do movimento de um projétil num conjunto de parâmetros. Este aparato, operado remotamente, é acedido via web, onde primeiramente é reservado um intervalo de tempo. O conjunto de parâmetros (“Bola”, “Altura de lançamento” e “Ângulo de lançamento”) da máquina permite suportar vários cenários de ensino da Física, com diferentes complexidades.

A detailed description of the morphology of the digestive organs of Enteroctopus megalocyathus (Gould, 1852) and Loligo sanpaulensis Brakoniecki, 1984 is given. The mandibles, the crop diverticulum, a doubly coiled caecum, the loop of the medium intestine and the appendages of the digestive gland are first described for E. megalocyathus. The most outstanding finding in L. sanpaulensis is the location of the single posterior salivary gland, wholly embedded in the digestive gland.

The structure of the male reproductive tract was described in Uca uruguayensis Nobili, 1901, by using histological methods, scanning electron microscopy techniques, and stereoscopic observations of fresh material. The aim of this work was to establish the functional changes associated with sexual maturation. The morphology of the first (G1) and second (G2) pair of gonopods was described. The male reproductive tract consists of paired organs: testes, and tubular and convoluted vas deferens (VD) ending with a terminal ampoule (TA).The (VD) is composed of three parts: anterior (AVD), medial (MVD) and posterior (PVD). The AVD and MVD are lined by a single layer of cubical cells. The PVD epithelial cells are columnar with elongated nuclei. The terminal ampoule comprises four interconnecting chambers and is externally surrounded by connective tissue. The study of testes and vas deferens at different times along the year suggests that U. uruguayensis has a single and continuous reproductive season from December to March. The TA has not been described in other brachyurans and this structure is novel to Brachyura.

The prevalence of hyponutrition in cystic fibrosis is high although it may vary according to the different studies. Detection of hyponutrition should be done by combining different methods, depending on their availability. However, the simplest and most validated criterion is to measure at each visit the weight (and height in children) in order to calculate the body mass index and categorizing hyponutrition according to absolute criteria: in adults < 18.5 kg/m(2), and in children as percentiles of the body mass index. Worsening of the nutritional status is directly related with the decrease in lung function parameters and it has been proposed as a morbidity (and even mortality) predictive factor in people with cystic fibrosis, independently of the level of pulmonary dysfunction. Exocrine pancreatic insufficiency is present is approximately 70-90% of the patients with cystic fibrosis and the genotype-phenotype correlation is high. Most of the patients with exocrine pancreatic insufficiency tolerate a high-fat diet provided that they are treated with pancreatic enzymes at appropriate doses. The prevalence of diabetes increases with age, reaching up 40% of the cases in patients older than 30 years. Clinical liver involvement is less prevalent (it approximately affects 1/3 of the patients). Other intestinal complications such as meconial ileus, gastroesophageal reflux, obstruction of the distal intestine, or fibrosing colon disease may also condition malnourishment. In patients with cystic fibrosis, a usual high-fat diet providing 120%-150% of the recommended calories is advised. If the nutritional goals are not achieved or maintained with diet modifications, artificial supplements may be added, although the recommendation for their use has not been endorsed by solid scientific evidences. The most frequently used preparations usually are polymeric or hypercaloric. The indications for enteral (through a tube, especially gastrostomy) or parenteral nutritional support are similar to those used in other pathologies. Dietary and nutritional control should be included in a multidisciplinary program allowing the improvement of the functional capacity and the quality of life and reducing, at least from a theoretical viewpoint, the morbimortality associated to malnourishment in these patients.
