Lead in terrestrial game birds from Spain

[EN] We analysed exposure to Pb and its relationship with lead-based ammunition in seven species of terrestrial game birds-common woodpigeon (Columba palumbus), rock dove (Columba livia), stock dove (Columba oenas), European turtle-dove (Streptopelia turtur), red-legged partridge (Alectoris rufa), Barbary partridge (Alectoris barbara) and common quail (Coturnix coturnix)-from rural and urban areas in different parts of Spain (Valencia, Castilla-La Mancha, Castilla y Leon, Madrid, Islas Canarias and Navarra). A total of 530 liver samples were analysed, and the presence of Pb pellets was studied in the crop, gizzard and intestine; the state and appearance of these organs were also analysed. The number of specimens suspected to have ingested Pb shot was 28 (5.6%), and the geometric mean concentration of hepatic Pb was 0.054 mu g g(-1) (wet weight, ww). A low percentage of samples (4.8%) were above the abnormal exposure threshold (0.65 mu g g(-1) ww), and, in these specimens, renal Pb concentrations were determined. Common woodpigeons and rock doves from Madrid were found to have high concentrations of Pb in their livers, and, so, both species can be considered to be good bioindicators of Pb contamination in rural (common woodpigeons) and urban (rock doves) environments. Partridges bred for hunting may be more prone to ingesting pellets from the environment, a fact that should be taken into account in management decisions.This study was funded by the Spanish Sectoral Federation of Weapons and Ammunition (FSA).

Nitro-fatty acids in plant signaling: Nitro-linolenic acid induces the molecular chaperone network in Arabidopsis

Nitro-fatty acids (NO-FAs) are the product of the reaction between reactive nitrogen species derived of nitric oxide (NO) and unsaturated fatty acids. In animal systems, NO-FAs are considered novel signaling mediators of cell function based on a proven antiinflammatory response. Nevertheless, the interaction of NO with fatty acids in plant systems has scarcely been studied. Here, we examine the endogenous occurrence of nitro-linolenic acid (NO-Ln) in Arabidopsis and the modulation of NO-Ln levels throughout this plant’s development by mass spectrometry. The observed levels of this NO-FA at picomolar concentrations suggested its role as a signaling effector of cell function. In fact, a transcriptomic analysis by RNA-seq technology established a clear signaling role for this molecule, demonstrating that NO-Ln was involved in plant defense response against different abiotic-stress conditions, mainly by inducing heat shock proteins and supporting a conserved mechanism of action in both animal and plant defense processes. Bioinformatics analysis revealed that NO-Ln was also involved in the response to oxidative stress conditions, mainly depicted by HO, reactive oxygen species, and oxygen-containing compound responses, with a high induction of ascorbate peroxidase expression. Closely related to these results, NO-Ln levels significantly rose under several abiotic-stress conditions such as wounding or exposure to salinity, cadmium, and low temperature, thus validating the outcomes found by RNA-seq technology. Jointly, to our knowledge, these are the first results showing the endogenous presence of NO-Ln in Arabidopsis (Arabidopsis thaliana) and supporting the strong signaling role of these molecules in the defense mechanism against different abiotic-stress situations.C.M.-P. thanks the University of Jaén for funding the Ph.D. fellowship.

Cancer Impacts Prognosis on Mortality in Patients with Acute Heart Failure: Analysis of the EPICTER Study

Introduction: Heart failure (HF) and cancer are currently the leading causes of death worldwide, with an increasing incidence with age. Little is known about the treatment received and the prognosis of patients with acute HF and a prior cancer diagnosis. Objective: to determine the clinical characteristics, palliative treatment received, and prognostic impact of patients with acute HF and a history of solid tumor. Methods: The EPICTER study (“Epidemiological survey of advanced heart failure”) is a cross-sectional, multicenter project that consecutively collected patients admitted for acute HF in 74 Spanish hospitals. Patients were classified into two groups according to whether they met criteria for acute HF with and without solid cancer, and the groups were subsequently compared. A multivariable logistic regression analysis was conducted, using the forward stepwise method. A Kaplan–Meier survival analysis was performed to evaluate the impact of solid tumor on prognosis in patients with acute HF. Results: A total of 3127 patients were included, of which 394 patients (13%) had a prior diagnosis of some type of solid cancer. Patients with a history of cancer presented a greater frequency of weight loss at admission: 18% vs. 12% (p = 0.030). In the cancer group, functional impairment was noted more frequently: 43% vs. 35%, p = 0.039). Patients with a history of solid cancer more frequently presented with acute HF with preserved ejection fractiono (65% vs. 58%, p = 0.048) than reduced or mildly reduced. In-hospital and 6-month follow-up mortality was 31% (110/357) in patients with solid cancer vs. 26% (637/2466), p = 0.046. Conclusion: Our investigation demonstrates that in-hospital mortality and mortality during 6-month follow-up in patients with acute HF were higher in those subjects with a history of concomitant solid tumor cancer diagnosis

Evaluación de tres leguminosas como coberturas asociadas con maíz en el trópico subhúmedo

Evaluación de tres leguminosas como coberturas asociadas con maíz en el trópico subhúmedo. El objetivo fue evaluar el potencia l de tres leguminosas como coberturas para mejorar el sistema de producción de maíz. Se evaluaron cuatro tratamie ntos: 1) maíz solo; 2) maíz y Phaseolus lunatus de ciclo corto de semilla blanca 3) maíz y Phaseolus lunatus de ciclo largo de semilla blanca y 4) maíz y frijol terciopelo (Mucuna sp.) en un diseño experimental de bloques al azar, con cuatro réplicas, durante cuatro ciclos de cultivo (1999-2002) en Yucatán, México. Se midió la biomasa de cultivos, pH, N total, mineralización potencia l anaerobia del nitrógeno, evolución del CO 2, potasio (K), fósforo (P) y materia orgánica del suelo, biomasa y frecuencia de arvenses. La cantidad de rastrojo en los tratamie ntos con leguminosas fue: 3436, 3425 y 4018 kg MS /ha para el primero, segundo y tercer año, respectivamente. El nitrógeno aportado por los rastrojos al maíz fue 25,8; 31,9; 52,8 y 43,4 kg/ha para los tratamie ntos 1, 2, 3 y 4, respectivamente. El rendimie nto de grano de maíz fue en promedio 841, 843 y 460 kg MS /ha para el primero, segundo y tercer ciclo, respectivamente; sin diferencia s entre tratamie ntos. En el tercer ciclo, el frijol terciopelo disminuyó la biomasa de arvenses de 126 a 58 g MS /m2. Las coberturas ejercieron poca influencia en las variables de suelo y rendimie nto de grano de maíz

2013. Documento Sevilla de Consenso sobre Alternativas a la Transfusión de Sangre Alogénica. Actualización del Documento Sevilla

La transfusión de sangre alogénica (TSA) no es inocua, y como consecuencia han surgido múltiples alternativas a la misma (ATSA). Existe variabilidad respecto a las indicaciones y buen uso de las ATSA. Dependiendo de la especialidad de los médicos que tratan a los pacientes, el grado de anemia, la política transfusional, la disponibilidad de las ATSA y el criterio personal, estas se usan de forma variable. Puesto que las ATSA tampoco son inocuas y pueden no cumplir criterios de coste-efectividad, la variabilidad en su uso es inaceptable. Las sociedades españolas de Anestesiología y Reanimación (SEDAR), Hematología y Hemoterapia (SEHH), Farmacia Hospitalaria (SEFH), Medicina Intensiva y Unidades Coronarias (SEMICYUC), Trombosis y Hemostasia (SETH) y Transfusiones Sanguíneas (SETS) han elaborado un documento de consenso para el buen uso de la ATSA. Un panel de expertos de las 6 sociedades ha llevado a cabo una revisión sistemática de la literatura médica y elaborado el 2013. Documento Sevilla de Consenso sobre Alternativas a la Transfusión de Sangre Alogénica. Solo se contempla las ATSA dirigidas a disminuir la transfusión de concentrado de hematíes. Se definen las ATSA como toda medida farmacológica y no farmacológica encaminada a disminuir la transfusión de concentrado de hematíes, preservando siempre la seguridad del paciente. La cuestión principal que se plantea en cada ítem se formula, en forma positiva o negativa, como: «La ATSA en cuestión reduce/no reduce la tasa transfusional». Para formular el grado de recomendación se ha usado la metodología Grades of Recommendation Assessment, Development and Evaluation (GRADE)
