Identifying N fertilizer management strategies to reduce ammonia volatilization: Towards a site-specific approach.

Concerns about ammonia (NH3) losses from nitrogen (N) mineral fertilizers have forced policymakers to set emission reduction commitments across Europe. Although best available techniques (BATs) have been recommended, large uncertainties still exist due to poorly targeted site-specific approaches that might compromise their effectiveness. Here we proposed and tested a conceptual framework designed to identify most effective BATs that reduce NH3 at the site-specific level. The study was conducted in the Veneto region, northeast Italy. After the mapping of NH3 emission potential areas, BATs and business-as-usual N fertilization scenarios were assessed using a modified version of the DNDC agroecosystem model and compared with urea broadcast distribution under different pedo-climatic conditions. The most promising practices were further tested in a field experiment using a wind tunnel combined with a FTIR gas analyzer. Results showed that closed-slot injection reduced NH3 emissions with any type of mineral or organic fertilizers. Injected application, with ammonium nitrate or organic fertilizers, reduced NH3 loss in maize by 75% and 96%, respectively, and in winter wheat by 87% and 98%, compared to surface broadcast. Injection was the most promising technology to support, being already available to farmers. However, some increase in nitrate leaching was observed, mostly in case of winter wheat (+24% for AN injection; +89% for organic fertilizers). By contrast, urea incorporation with hoeing, the most common technique used by farmers in spring crops, did not show satisfactory results, because the partial burial of urea caused strong NH3 emissions that were even higher compared to surface broadcast. Recommended NH3 reduction techniques should be tailored to local pedo-climatic and management conditions, and evaluated, in a holistic approach, considering all N fluxes in the environment.

Reflexión teórica sobre el arte del cuidado / Theoretical reflection on the art of care / Reflexão teórica sobre a arte do cuidado

Introducción: Con la construcción del estado del arte se identificó la necesidad de conceptualizar el arte del cuidado con la siguiente interrogante: ¿se concibe el arte del cuidado de enfermería como fenómeno de estudio desde la revisión del pensamiento teórico de enfermería? Este análisis contribuye a la fundamentación filosofica estética de la disciplina de enfermería y su resignificación para la enseñanza y la práctica, de tal forma que el cuidado adquiera el sentido humanístico para la autonomía profesional. Desarrollo: Se analiza el cuidado desde la visión de algunos filósofos y teóricas de enfermería para contextualizar el fenómeno de estudio; posteriormente se describen las concepciones del arte del cuidado y conocimiento estético más significativas desde Florence Nightingale hasta Vera Regina Waldow. Para el análisis de los hallazgos se consideran las concepciones del arte como conocimiento, como actividad práctica y como sensibilidad establecidas por Abaggnano. Conclusiones: El arte del cuidado se sustenta según las concepciones fundamentales del arte, principalmente como actividad práctica, asimismo se identifican las acepciones del arte como conocimiento y como sensibilidad. En síntesis, hasta este momento se puede decir que el arte del cuidado se da en una relación intersubjetiva, la enfermera (ro) hace una abstracción de la realidad de la persona y esta hace una autopercepción para objetivar sus necesidades. De esta interacción se derivan las acciones cuidativas basadas en el amor, en el respeto a la dignidad de la persona.

Introduction: Considering the construction of the state of art, the need to conceptualize the art of care was identified through the following question: Is the nursing care art conceived as a phenomenon of study from the perspective of the nursing theoretical thought? This analysis contributes to the philosophical and aesthetical foundations of nursing teaching and practice so that care acquires the humanistic sense for the professional autonomy. Development: Care is analyzed from the vision of some philosophers and theoreticians of nursing in order to contextualize the phenomenon of study; then, the most significant conceptions of the art and aesthetics of care, from Florence Nightingale until Vera Virginia Waldow are described. The Abaggnano conceptions of art as knowledge, practical activity, and sensibility serve as framework to this analysis. Conclusions: The art of care is supported by the fundamental conceptions of art, mainly as a practical activity, but also as knowledge and sensibility. Therefore, it can be expressed that the art of care develops from and into an intersubjective relationship: the nurses abstract the reality of the persons, while the persons self-perceive to objectivize their needs. From these interactions, caring actions based on love, respect, and dignity are developed.

A surveillance system for diseases of companion animals in the Veneto region (Italy).

Experts and international public health organisations stress the lack of surveillance systems for companion animal diseases and the need to implement such surveillance as a priority of the 'One Health' perspective. This paper presents the features of a system for the collection, analysis, interpretation and dissemination of data regarding the health status of pets in the Veneto region (Italy). The system involved the construction of a Web-based database containing the diagnoses of transmissible and non-transmissible diseases of dogs and cats made by veterinarians in their practices, hospitals, kennels and catteries. Each diagnosis constitutes a single record, also containing data on the identification of the individual animal and on several characteristics of epidemiological relevance. The World Health Organization (WHO) 10th revision of the International Classification of Diseases (ICD-10) for human diseases has been adapted to canine and feline diseases to standardise the diagnostic nomenclature. Software has been specifically created for online data entry and data management. The first results show that the main disorders were digestive (21%), dermatological (18%) and cardiovascular (11%) among 1,087 diagnostic records in dogs, and digestive (23%), dermatological (15%) and urinary (14%) among 289 diagnostic records in cats. The main causes of death are represented by cardiovascular (21%) and gastrointestinal (21%) diseases in dogs and by urinary (31%) disorders in cats. At present, no institutional surveillance system for companion animal health exists in Italy, and veterinarians joining this project and sharing the outcomes of their clinical activity are acting on a voluntary basis.

Aussi bien les experts que les organisations internationales oeuvrant dans le domaine de la santé publique soulignent l'absence de systèmes de surveillance dédiés aux maladies des animaux de compagnie, alors que la mise en place de cette surveillance constitue une priorité dans une perspective « Une seule santé ¼. Les auteurs décrivent les caractéristiques d'un système introduit en Vénétie (Italie) pour collecter, analyser, interpréter et diffuser des données sur la situation sanitaire des animaux de compagnie. Le système repose sur une base de données en ligne alimentée par les rapports de diagnostic sur les maladies transmissibles et non transmissibles des chiens et des chats établis par les vétérinaires dans leur cabinet, à l'hôpital ou dans les élevages ou pensions pour chiens et chats. Chaque diagnostic fait l'objet d'une notification spécifique où sont également consignées les données d'identification individuelle de l'animal et les caractéristiques pertinentes au plan épidémiologique. La classification internationale statistique des maladies (ICD­10) de l'Organisation mondiale de la santé (OMS), qui concerne les maladies humaines, a été adaptée aux maladies des chiens et des chats afin d'utiliser une nomenclature standardisée des diagnostics. Un logiciel spécifique a été créé pour la saisie en ligne des données et leur gestion. D'après les premiers résultats, les principales affections diagnostiquées étaient, chez le chien (sur 1 087 rapports de diagnostic), des maladies digestives (21 %), dermatologiques (18 %) et cardio-vasculaires (11 %) et, chez le chat (sur 289 rapports de diagnostic), des maladies digestives (23 %), dermatologiques (15 %) et urinaires (14 %). Les principales causes de mortalité étaient respectivement les maladies cardio-vasculaires (21 %) et gastro-intestinales (21 %) chez le chien et les maladies du système urinaire (31 %) chez le chat. À l'heure actuelle, aucun système institutionnel de surveillance n'est en place en Italie pour les animaux de compagnie, de sorte que les vétérinaires qui participent à ce projet et partagent leurs résultats cliniques le font sur une base volontaire.

Tanto especialistas como organizaciones internacionales dedicadas a temas de salud pública hacen hincapié en la ausencia de sistemas de vigilancia de las enfermedades de los animales de compañía y en la necesidad de instaurar tal vigilancia como elemento prioritario de los planteamientos de «Una sola salud¼. Los autores presentan las características de un sistema destinado a reunir, analizar, interpretar y difundir datos sobre el estado de salud de los animales de compañía en la región italiana del Veneto. Para instituir ese sistema se creó una base de datos en línea que centraliza información sobre los diagnósticos de enfermedades transmisibles y no transmisibles de perros y gatos realizados por veterinarios en el ejercicio de su labor en consultorios, hospitales y residencias caninas y felinas. Cada diagnóstico constituye un registro único, que también contiene datos sobre la identidad del animal en cuestión y sobre una serie de aspectos de importancia epidemiológica. Con objeto de normalizar la nomenclatura de diagnóstico se adaptó a las enfermedades caninas y felinas la Clasificación Internacional de Enfermedades, décima revisión (CIE­10), de la Organización Mundial de la Salud (OMS), que se aplica a las enfermedades humanas. También se crearon programas informáticos destinados específicamente a la introducción de datos en línea y a su gestión. Los primeros resultados muestran que los principales trastornos en los perros, de los 1.087 diagnósticos registrados, fueron los digestivos (21%), seguidos de los dermatológicos (18%) y los cardiovasculares (11%). En el caso de los gatos, con 289 diagnósticos registrados, las dolencias más importantes fueron las digestivas (23%), las dermatológicas (15%) y las urinarias (14%). En el perro, las principales causas de mortalidad fueron las enfermedades cardiovasculares (21%) y gastrointestinales (21%), y en el gato las patologías urinarias (31%). Actualmente no existe en Italia ningún sistema institucional de vigilancia de la salud de los animales de compañía, y los veterinarios que participan en este proyecto y comparten los resultados de su praxis clínica lo hacen con carácter voluntario.

Geranylgeranyl transferase inhibition stimulates anti-melanoma immune response through MHC Class I and costimulatory molecule expression.

Defective antitumor immune responses are frequent consequences of defects in the expression of major histocompatibility complex (MHC) class I and costimulatory molecules. We demonstrated that statins, inhibitors of HMGCoA reductase, enhance mIFN-gamma induced expression of MHC class I antigens on murine B16F10 melanoma. GGTI-298, a geranylgeranyl transferase I inhibitor, but not FTI-277, a farnesyl transferase inhibitor, mimics this effect of statins. This effect is related to peptide transporter protein TAP1 up-regulation. Simultaneously, GGTI-298 induces the expression of CD80 and CD86 costimulatory molecules. C3 exoenzyme, which selectively inactivates Rho proteins, phenocopies the effects of GGTI-298, indicating a role for Rho proteins in these events. Furthermore, the treatment of B16F10 cells with GGTI-298 or C3 exoenzyme associated with mIFN-gamma induces in vivo tumor growth slowing down in immunocompetent but not in nu/nu syngeneic mice. Both in vivo injections and in vitro restimulation of splenocytes with GGTI-298- and mIFN-gamma-treated B16F10 cells induces an enhancement of specific CD8 T lymphocytes labeled by TRP-2/H-2K(b) tetramers. Finally, these effects are not limited to mouse models since they were also reproduced in two human melanoma cell lines. These observations indicate that protein geranylgeranylation as well as Rho protein are critical for costimulatory and IFN-gamma-dependent MHC class I molecule expression in melanoma.

Neuropsychological dysfunction in patients suffering from end-stage chronic obstructive pulmonary disease.

Few studies have examined the neuropsychological sequelae associated with end-stage pulmonary disease. Neuropsychological data are presented for 47 patients with end-stage chronic obstructive pulmonary disease (COPD) who were being evaluated as potential candidates for lung transplantation. Although patients exhibited a diversity of neurocognitive deficits, their highest frequencies of impairment were found on the Selective Reminding Test (SRT). Specifically, over 50% of the patients completing the SRT exhibited impaired immediate free recall and consistent long-term retrieval deficits, while more than 44% of these individuals displayed deficient long-term retrieval. Deficient SRT long-term storage strategies, cued recall, and delayed recall were exhibited by between 26% and 35% of these patients, while more than 32% of this sample displayed elevated numbers of intrusion errors. Over 31% of the patients completing the Wisconsin Card Sorting Test (WCST) failed to achieve the expected number of categories on this measure, while more than 23% of these individuals demonstrated elevated numbers of perseverative errors and total errors. Clinically notable frequencies of impairment (greater than 20% of the sample) were also found on the Trail Making Test (TMT): Part B and the Wechsler Memory Scale-R (WMS-R) Visual Reproduction II subtest. Minnesota Multiphasic Personality Inventory-2 (MMPI-2) personality assessments indicated that patients were experiencing a diversity of somatic complaints and that they may have been functioning at a reduced level of efficiency. These findings are discussed in light of patients' end-stage COPD and factors possibly contributing to their neuropsychological test performances. Implications for clinical practice and future research are also included.
