Abstract: La hemodiafiltración "on-line" postdilucional es el modo de infusión más eficaz para la eliminación de moléculas de diferentes pesos moleculares; también se ha relacionado con un mejor control de la anemia así como del estado nutricional del paciente, confiriendo una menor morbilidad al paciente en hemodiálisis. Recientemente, se han incorporado importantes avances en la tecnología que permiten la prescripción automática del flujo de infusión lo que podría reducir las cargas de enfermería. El objetivo del presente estudio es evaluar la eficacia de la infusión automática comparada con la manual en la HDF on-line postdilucional, mediante la medición del volumen convectivo final y del aclaramiento de peque as moléculas mediante el Kt. También se evalúan las cargas de enfermería medidas por el número de intervenciones relacionadas con la técnica, la valoración de comodidad y eficacia percibida por el personal de enfermería y si hay diferencias en el confort del paciente a lo largo de la sesión. Se dise a un estudio prospectivo sobre 86 pacientes; tras tres sesiones con cada uno de los modos de reinfusión se aprecian diferencias significativas tanto en el volumen de sustitución (1,5litros) como en la dosis de diálisis administrada medida mediante Kt (1,02 litros), que son superiores en la forma automática. Por otra parte, la valoración subjetiva del personal de enfermería es muy superior en el modo automático frente al manual tanto en eficacia percibida como en comodidad. El paciente también expresa un mayor confort en las sesiones con reinfusión automática al disminuir en número de alarmas acústicas y favorecer el descanso. La reinfusión automática aunque con poca repercusión clínica, se muestra como una buena alternativa sobretodo en lo que respecta a la adaptación de la técnica por parte del personal y del propio paciente.

Abstract: Las técnicas de hemodiafiltración (HDF) con altos volúmenes convectivos, constituyen una interesante forma de depuración por su aproximación a la del ri ón nativo. De entre ellas, la HDF on-line postdilucional es el modo de infusión más eficaz para la eliminación de moléculas de diferentes pesos moleculares. Recientes avances en la tecnología permiten la prescripción automática del flujo de infusión (Qi), resultando al menos tan eficaz como el manual. El objetivo del presente estudio es evaluar si es posible incrementar la eficacia de la infusión automatizada en la HDF on-line postdilucional, incrementando manualmente el Qi inicial, mediante la medición del volumen convectivo final y del Kt. Por otro lado, se evalúan las cargas de enfermería medidas por el número de intervenciones relacionadas con la técnica. En todos los pacientes (n 96) se realizan 3 sesiones de diálisis (ST 5008 Fresenius Medical Care) con reinfusión automática, y seguidamente, otras 3 sesiones con reinfusión automatizada manual incrementando el Qi en 10 ml/min al medido automaticamente. De los resultados obtenidos, se aprecian diferencias significativas (p<0,001) en el volumen de reinfusión, siendo un 6% mayor en la forma automatizada manual (23,01 ± 2,22 litros) que en la automatizada (21,7 ± 2,62 litros). El 75% de los pacientes alcanzan 20 litros o más con la autosustitución, frente al 87,5% con la sustitución automatizada manual (p<0,001). No existen diferencias en cuanto al Qb, Qd, tiempo efectivo de diálisis y Kt. El número de intervenciones por alarmas relacionadas con la técnica del personal de enfermería es superior (p=0,001). Haemodiafiltration (HDF) techniques with high convective volumes are an interesting form of filtering due to their approximation to the native kidney. Among them, post-dilution on-line HDF is the most efficacious form of infusion for eliminating molecules with different molecular weights. Recent advances in technology permit the automatic prescription of the infusion flow (Qi), proving at least as efficacious as manual infusion. The aim of this study is to assess whether it is possible to increase the efficacy of automated infusion in post-dilution on-line HDF by manually increasing the initial Qi by measuring the final convective volume and Kt. The nursing workloads are also assessed, measured by the number of interventions related to the technique. In all patients (n 96) 3 dialysis sessions are carried out (ST 5008 Fresenius Medical Care) with automatic reinfusion, followed by another 3 sessions with manual automated reinfusion increasing the Qi by

Abstract: the dialysis dose affects survival of patients undergoing dialysis, as well as affecting the correction of anaemia, the nutritional state and the control of blood pressure, among others. some authors have indicated the dialysis fluid flow rate as a determining factor in the dialysis dose for patients undergoing high-flow haemodialysis and haemodiafiltration. the aim of this study is to evaluate the impact on the dialysis efficacy of different flow rates of dialysis fluid in patients treated with on-line post-dilution haemodiafiltration and conventional haemodialysis, by measuring the final convective volume and rinse solution volume of small molecules using kt. in all patients, 9 consecutive dialysis sessions were carried out varying the qd: 3 sessions with qd 500 ml/min, 3 sessions with qd 800 ml/min and 2 sessions with autoflow. from the results obtained, kt is shown to be significantly higher with qd 800 ml/min (59.69 ± 6.07 litres) compared to qd 500 ml/min (56.51 ± 6.33 litres, p<0.001) and autoflow (58.02 ± 4.89 litres); and kt in autoflow was found to be higher (p<0.001) than qd 500 ml/min. the increase in flow rate of dialysis fluid means an increase in the dialysis dose in patients treated with online haemodiafiltration. the autoflow achieves an appreciable increase in dose compared to qd of 500 ml/min with a minimum additional cost, and should therefore be considered as a measure in an overall treatment framework, permitting individualization of treatment for each patient.

Abstract: Groups of 6–7 female lactating rabbits maintained with their litters or separated from them for 48 h were killed by decapitation on day 11 post-partum, at 6 different time points throughout a 24-h cycle, starting at 0900 h. Plasma levels of prolactin, FSH and LH were measured by specific double antibody radio-immunoassays.Plasma level of prolactin in control and separated does changed in a similar way throughout the day, showing two maxima, at 0500–0900 h and at 1700–2100 h, respectively. Litter separation significantly augmented plasma FSH and LH and disrupted their 24-h rhythmicity.Since previous studies had shown that litter separation for short periods of time augmented sexual receptivity and fertility of the doe, the changes in FSH and LH reported may influence the massive release of gonadotropin releasing hormone, LH and FSH triggered by mating or artificial insemination in litter-separated mothers.In nursing rabbits, sexual receptivity and fertility achieved after artificial insemination is depressed during the period of lactation, presumably through a hormonal antagonism between prolactin and gonadotropin release [1-3]. Several studies have demonstrated that separation of the doe from its litter for short periods of time, prior to artificial insemination, is very effective in stimulating ovarian activity in the mother [4-6], with endocrine changes that may explain the activation of ovarian function [7-9] Thus, separation of the does from their litters could be an effective procedure to augment breeding efficiency under farm conditions [5-7].It must be noted that the published studies on the endocrine changes taking place in the doe after litter separation have been performed at single time points in the daily cycle, usually in the morning, which is an important drawback in view of the circadian nature of the secretion of the pituitary hormones involved [10,11]. Indeed a number of circadian functions have been examined in rabbits [12-17], but there is no info

Abstract: treatment of toxoplasmosis usually causes secondary effects. it is important to find active substances extracted from natural organisms. in this work we studied some arthropod extracts that have effect against toxoplasma multiplication inside mouse macrophages. after studying 382 extracts, 23 were selected on the basis of the activity and we found that 13 extracts from orders polydesmida, lepidoptera, orthoptera and hymenoptera exerted an important inhibition of toxoplasma multiplication.
