RESUMO: Os objetivos do presente estudo foram verificar se as temperaturas corpóreas e locais se alteram após exercício de alta intensidade e curta duração (prova de laço em dupla) e se treinamentos distintos podem influenciar nestas alterações. Foram utilizados 12 animais, machos e fêmeas, com idade entre 3 e 6 anos e peso médio de 450kg. Os animais foram divididos em dois grupos: treino regular (GTR) e treino esporádico (GTE). As aferições da temperatura por meio de termografia infravermelha foram feitas por uma câmera termal específica. As medições das temperaturas das regiões ocular, toracolombar, tendíneas distais (membros torácicos e pélvicos) e garupa foram realizadas 30 minutos antes, imediatamente depois, uma, duas, seis e 24 horas após a simulação de competição. No GTR houve aumento de temperatura ocular duas horas após o exercício, retornando ao basal apenas 24 horas depois. No GTE o aumento ocorreu imediatamente após o exercício e retornando ao basal duas horas depois. As temperaturas da região dos tendões dos membros pélvicos e garupa (lado direito) elevaram-se imediatamente após o exercício e não retornaram ao basal após 24 horas. O exercício de laço em dupla aumentou as temperaturas superficiais nas regiões distolateral de membros torácicos e pélvicos, garupa e região toracolombar de ambos os grupos e da temperatura ocular do GTE. A frequência de treinamento influenciou o perfil de temperatura superficial na região distal de membros pélvicos, garupa e toracolombar.

ABSTRACT: This study aimed to verify whether the body and local temperatures change after high-intensity, short-duration exercise (team roping) and whether different pieces of training influence these changes. To this end, twelve animals, males and females, aged 3-6 years, with an average weight of 450 kg, were used. The horses were divided into two groups: regular training (RTG) and sporadic training (STG). The surface temperatures were assessed using a specific thermal camera. Temperatures of the ocular, thoracolumbar, distal tendon (thoracic and pelvic limbs) and croup regions were measured 30 min before, immediately after, and one, two, six and 24 hours after competition simulation. In the RTG, there was an increase in surface eye temperature two hours after exercise, returning to baseline level 24 hours later. In the STG, increase in eye temperature occurred immediately after exercise and returned to baseline level two hours later. Temperature of the pelvic limb tendons and croup (right side) rose immediately after exercise and did not return to baseline level 24 hours later. Team roping exercise increased the surface temperature of the distolateral thoracic and pelvic limb, croup and thoracolumbar regions in both groups and the eye temperature in the STG. Training frequency influenced the surface temperature profile in the distolateral pelvic limb, croup and thoracolumbar regions.

RESUMO: O objetivo desse estudo foi o de avaliar as frações proteicas em secreções colostrais de vacas acometidas por mastite clínica imediatamente após o parto. Para tanto, foram utilizadas 30 vacas da raça Holandesa distribuídas em três grupos, a saber: Grupo I (GI)- 10 vacas pluríparas sadias, Grupo II (GII) 10 vacas pluríparas que pariram com mastite assintomática e Grupo III (GIII) 10 vacas pluríparas que pariram com mastite clínica. Foram avaliadas as concentrações de imunoglobulina a (IgA), lactoferrina (LF), albumina, imunoglobulina G (IgG), β-lactoglobulina (β-Lg) e α-lactoalbumina (α-La) por meio da eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE).Observou-se que a IgG, LF e a albumina variaram entre as glândulas com mastite assintomática e clínica quando comparadas às glândulas sadias, e que a presença de um único microrganismo é capaz de promover alterações no proteinograma, com ou sem manifestações clínicas na glândula mamária.

ABSTRACT: The aim of this study was to evaluate the protein fractions in colostral secretions of cows affected by mastitis immediately after calving. Therefore, 30 Holstein cows were divided into three groups: Group I (GI) composed of ten multiparous cows calving without mastitis; Group II (GII) composed of ten multiparous cows calving with subclinical mastitis, and Group III (GIII) composed of ten multiparous cows calving with mastitis. The concentration of immunoglobulin A (IgA), lactoferrin (LF), albumin, immunoglobulin G (IgG), β-lactoglobulin (β-Lg) and α-lactoalbumin (α-La) was determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). It was found that the IgG, LF and albumin vary among glands of subclinical and clinical mastitis and healthy and that the presence of a bacteria in the mammary gland was the key role for changing of the pattern of serum protein source.

Objectives: Beyond the current economic crisis, the Spanish National Health System (SNHS) has a problem of long-term sustainability that has its roots in changes in the morbidity patterns with the onset of chronic diseases and the acceleration of technological change, and with the rapid incorporation of new and expensive technologies. The aim of this paper is to explore the role of low value technology disinvestment as a strategy for SNHS sustainability. Material and methods: Narrative review and discussion of the relevant features of disinvestment, and disinvestment strategies in several countries. Results: Disinvestment is an explicit process of (partially or completely) withdrawing drugs, devices, practices or procedures with low or questionable clinical value. Very dissimilar healthcare systems such as those in Australia, New Zealand, United Kingdom or United States have launched disinvestment strategies adapted to their different contexts, while in Spain there remains a degree of reluctance to incorporate explicit mechanisms for decision-making on incorporation/disinvestment of health technologies with regard to the SNHS. Discussion: Low value technology disinvestment is complex. Many technologies are only candidates for partial withdrawal, or its value is controversial and, in addition, there are psychological and sociological barriers to disinvestment. Implementation of these strategies requires commitment from professionals and health authorities and cooperation from patients and citizens, which in turn should be carefully managed.

Objetivos: Más allá de la actual crisis económica, el Sistema Nacional de Salud (SNS) tiene un problema de sostenibilidad a largo plazo derivado de los cambios en los patrones de morbilidad con la irrupción de la cronicidad y la aceleración del cambio tecnológico con la rápida incorporación de nuevas tecnologías de elevado precio. El objetivo de este artículo es explorar el papel de la desinversión de tecnologías de bajo valor como estrategia para la sostenibilidad del SNS. Material y método: Revisión narrativa y discusión de las características relevantes de las estrategias de desinversión en varios países. Resultados: La desinversión es un proceso explícito mediante el cual dejan de financiarse de forma parcial o completa medicamentos, dispositivos, aparatos o procedimientos con bajo o dudoso valor clínico. Sistemas sanitarios muy dispares -como los de Australia, Nueva Zelanda, Reino Unido o Estados Unidos- han puesto en marcha estrategias de desinversión diferenciadas adaptadas a su contexto, mientras que en España se mantienen las reticencias a incorporar mecanismos explícitos para la toma de decisiones sobre la incorporación o desinversión de tecnologías sanitarias al SNS. Discusión: Desinvertir en tecnologías de bajo valor es complejo. Muchas tecnologías son sólo candidatas a desinversión parcial o su valor es objeto de controversia y, adicionalmente, existen barreras psicológicas y sociológicas a la desinversión. La implantación de estas estrategias requiere el compromiso de profesionales y administraciones sanitarias y la complicidad de pacientes y ciudadanos, compromiso que debe ser gestionado.

Introduction: Little work has been done on the contents of psychiatric consultancies in prisons. Aims: To explore the sociodemographic, clinical and treatment profile of the patients who were assessed in the psychiatric consultancy of three prisons. Methods: This is a prospective, longitudinal, descriptive and multicenter-based epidemiological study of patients who were assessed in the psychiatric consultacy of three prisons in the Autonomous Community of Valencia from 2009 to 2011. Sociodemographic, clinical and prison data was obtained from each patient. Their frequency was compared with Pearson's Ji² and averages with the ANOVA test or with The Kruskall-Wallis method. The probability of keeping the patients in schedule was calculated with Kaplan-Meier's curves and differences with the Mantel-Haenzsel method (Logrank) were established. A logistic regression model was designed to determine the data linked to frequent users. Results: 786 patients were assessed in 2,006 visits (2.5 visits/patient). 90% were male, 88.2% Spanish and their average age was 36 years. 29.9% suffered from an infectious chronic pathology. 69.5% used some kinds of substance. 59.2% suffered from personality disorder and 11.6% from the spectrum of schizophrenia. The most frequent medical profiles were: 49.1% with anxiety disorder, 20.8% depressive disorder and 11.7% psychotic disorder. These psychotic disorders meant a greater probability of 1.5 times for maintaining in schedule. The most commonly prescribed medications were quetiapine, mirtazapine, pregabalin and diazepam. Conclusion: There is a high prevalence of mental disorders in prisons. It is necessary to improve the available resources to deal with these pathologies in the most effective way.

Introducción: Existen pocos trabajos sobre el contenido de las consultas psiquiátricas en las prisiones. Objetivos: Explorar el perfil sociodemográfico, clínico y de tratamiento de los pacientes valorados en la consulta psiquiátrica de tres centros penitenciarios. Métodos: Estudio epidemiológico multicéntrico, descriptivo, longitudinal, y prospectivo de los pacientes valorados en la consulta psiquiátrica de tres prisiones de la Comunidad Valenciana durante 2009, 2010 y 2011. Se obtuvieron variables clínicas, sociodemográficas y penitenciarias de cada paciente. Las frecuencias se compararon mediante la Ji² de Pearson y las medias por el test de ANOVA o el método de Kruskall-Wallis. Se calculó la probabilidad de mantenerse en agenda psiquiátrica mediante curvas de Kaplan-Meier, estableciéndose las diferencias con el método de Mantel-Haenzsel (Logrank). Se diseñó un modelo de regresión logística para determinar las variables asociadas a hiperfrecuentación. Resultados: Se valoraron 786 pacientes en 2.006 consultas (2,5 visitas/paciente). El 90% eran varones y el 88,2% españoles, con una edad media de 36,0 años. El 29,9% tenían patología infecciosa crónica asociada. El 69,5% consume algún tipo de sustancia. El 59,2% sufría un trastorno de personalidad y el 11,6% del espectro de la esquizofrenia. Los cuadros clínicos más frecuentes fueron; 49,1% cuadros ansiosos, 20,8% depresivos y 11,7% síntomas psicóticos. Los trastornos psicóticos supusieron 1,5 veces más probabilidad (IC 95%; 1,1-1,9) de mantenerse más tiempo en agenda. Los fármacos más prescritos fueron quetiapina, mirtazapina, pregabalina y diacepam. Conclusiones: Los trastornos mentales en prisión son muy prevalentes. Es necesario potenciar los recursos disponibles para una adecuada atención de estas patologías.

Leptopspirosis is a syndrome with different clinical manifestations including the most severe and often fatal forms of pulmonary disease of unknown etiology. Pulmonary injury during the inflammatory process has been associated with the excessive number of alveolar macrophages (AMs) and polymorphonuclear leukocytes stimulated in the lungs and with the production of reactive oxygen and nitrogen intermediates and other inflammatory mediators. The aim of the present work was to evaluate the cellular immune response of AMs or inflammatory cells of hamsters during leptospirosis. The activity of AMs was determined by measuring nitric oxide (NO) and protein production as well as inflammatory cell infiltration in bronchoalveolar lavage (BAL) fluid. Pulmonary activity during infection was monitored by measuring pH, pressure of oxygen (PaO2), and pressure of carbon dioxide (PaCO2) in blood samples. Cellular immune response and its role in the genesis of leptospirosis have been incriminated as the main causes of tissue and pulmonary injuries, which consequently lead to the pulmonary dysfunction in severe cases of leptospirosis. The present results show a low production of NO in both supernatant of alveolar macrophage culture and BAL. In the latter, protein production was high and constant, especially during acute infection. Total and differential cell count values were 2.5X10(6) on day 4; 7.3X10(6) on day 21; and 2.3X10(6) on day 28 after infection, with lymphocytes (84.04%) predominating over neutrophils (11.88%) and monocytes (4.07%). Arterial blood gas analysis showed pulmonary compromising along with the infectious process, as observed in parameter values (mean±SD) evidenced in the infected versus control group: PaO2 (60.47mmHg±8.7 vs. 90.09mmHg±9.18), PaCO2 (57.01mmHg±7.87 vs. 47.39mmHg±4.5) and pH (7.39±0.03 vs. 6.8±1.3). Results indicated that Leptospira infection in hamsters is a good experimental model to study leptospirosis. However, some of the immune parameters showed variations which might be associated with the animal species.

The aim of the present study was to investigate the kinetics of humoral and cellular responses during leptospirosis. We observed that the presence of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) was associated with antibody production and bacterial recovery, and the compromising of both TNF-alpha and IL-6 in the immunopathogenesis of leptospirosis during an experimental infection of BALB/c mice inoculated with Leptospira interrogans serovar Canicola was verified. Results showed higher levels of TNF-alpha and IL-6 in the initial phase of infection, in which the greatest bacterial clearance was observed. However, when the bacterial recovery was compared with the kinetics of the production of antibodies, the results revealed a kinetics proportionally inverted to antibody production. This fact may be related to some inhibitory factor which could be responsible for the selective suppression of the cellular immune response. We concluded that during leptospirosis there was a greater mobilization of the cellular immune response activity, mainly in the initial phase of the infectious process, for posterior involvement of the humoral response, and that both TNF-alpha and IL-6 could be associated with the immunopathogenesis of the disease.

Immune response to leptospirosis is mainly humorally mediated, and involves opsonization of leptospires for phagocytosis by macrophages and neutrophils. However, some aspects are still unknown. For a more detailed analysis of the cellular immune response to leptospirosis infection, trials were carried out in order to determine the hydrogen peroxide and nitric oxide (H2O2 and NO) production stimulated or not by Interferon-gamma. The participation of some specific cytokines, such as Tumor Necrosis Factor-alpha (TNF-alpha); Interferon-gamma (IFN-gamma); Interleukin-6 (IL-6); and Interleukin-4 (IL-4), in the immunopathology of this infection was also investigated. For this purpose, we analyzed the supernatant from peritoneal macrophage cell culture and the splenic cells of mice genetically selected as High (H) and Low (L) antibody producers, and inbred Balb/c mice infected with Leptospira interrogans serovar icterohaemorrhagiae. The IL-6 production varied from release peaks to inhibition in H, L, and Balb/c mice. Similar behavior was observed for IL-4, produced only by H and Balb/c mice. The three strains presented constant and elevated production of TNF-alpha until day 14, suggesting its effective participation in the initial phase of the infection. Meanwhile, all the three strains presented a constant and irregular IFN-gamma production, with release peaks between the 7th and 14th days in L mice. The H and Balb/c mice strains presented a higher tendency to Th2 response pattern, whereas L mice tended towards Th1 response.
