Forage Biomass and Bovine Live Weight Changes within Monospecific and Mixed Prairies over the Dry Season in Tropical México

In the tropical systems of cattle grazing, the limited period of forage production and low forage protein content and digestibility of the same, are the main constraints to increasing live weight gain. Grass-legume pasture improves forage quantity and quality and sowing mixed swards in both the wet and dry tropics is now common practice. However, much less is known if inclusion of a fodder tree as a third component could further improve forage parameters. The aim of this study was to evaluate three types of grasslands, grazed by cattle in the dry season of the dry tropics. Swards were established to compare: grass only (PP), grass-legume (PA) and silvo-pastoral (PSP) pastures on basis of forage on-offer, residual and disappeared and bullock’s daily live-weight gain. Species used were: Andropogon gayanus Kunth, Clitoria ternatea Linn and Morus alba Linn

Gestión clínica de la consulta: previsibilidad y contenido clínico (estudio SyN-PC)

Consulta imprevisible (Ip): no podemos prever su contenido (problemas agudos) y surgen inesperadamente. Engloba la consulta urgente. Consulta administrativa (Ad): tareas burocráticas (recetas, partes de confirmación, certificados). Consulta asistencial (As): prevenir, diagnosticar y tratar la enfermedad, o realizar seguimiento de ésta. Variables del paciente, el centro y la consultaResultadosEl 60% (n=1.809; IC del 95%, 58,69–61,59%) de los motivos fueron previsibles y el 40% (n=1.199; IC del 95%, 36,6–43,12%), imprevisibles. El 50% (n=1.509; IC del 95%, 47,26–53,06%) fueron consultas asistenciales y el 50% (n=1.499; IC del 95%, 46,34–53,39%), administrativas. El 40% (n=1.189; IC del 95%, 37,78–41,28%) fueron previsibles-administrativas y tan sólo un 21% (n=620; IC del 95%, 19,16– 22,06%) resultaron de carácter previsible-asistencial. El 30% (n=889; IC del 95%, 27,92–31,18%) fueron de carácter imprevisible–asistencial y el 10% (n=310; IC del 95%, 9,22– 11,4%), imprevisibles-administrativas. En los pacientes con un único motivo, el 48% (n=577; IC del 95%, 44,25–52,05%) fueron consultas previsibles-administrativas. Los centros docentes o informatizados tienen menos carga de consultas previsibles-administrativas. Éstas aumentan con la edad del paciente y con la presión asistencialConclusionesCasi un 40% de los motivos de consulta son previsibles-administrativos, lo que implica una gestión clínica inadecuada. Sería necesaria una intervención que permitiera liberar tiempo médico consumido en asuntos burocráticos para dedicarlo a la tarea asistencial propiamente dichaObjectivesTo describe care activity as a function of the nature of the consultation (predictability) and the needs of the patients (clinical content). To analyse the relationship of these with the characteristics of the consultation, of the patient and of the centreDesignMulti-centre, descriptive, observational study.SettingPrimary care. Area 17 of the Health Department of the Community of Valencia, with 197 316 inhabitants and 12 health centresParticipantsInformation gathering in real time by outside observer. Stratified randomised sampling of 2051 patients who gave rise to 3008 reasons for medical consultationMain measurementsPredictable consultations (Pr): their content can be foreseen (check-ups, picking up results). Unpredictable consultations (Unp): we cannot predict their content (acute problems may arise unexpectedly). These include urgent consultations. Administrative consultations (Ad): bureaucratic tasks (prescriptions, repeat sick-notes, sick certificates). Care consultations (Car): prevention, diagnosis and treatment of the illness, or monitoring of it. Variables here are the patient, the doctor and the consultationResults60% (1809) (95% CI, 58.69%–61.59%) of the reasons were Pr and 40% (1199) (95% CI, 36.6%–43.12%) were Unp. 50% (1509) (95% CI, 47.26%–53.06%) were Car, and 50% Ad (1499) (95% CI, 46.34%–53.39%). 40% (1189) (95% CI, 37.78%–41.28%) were Pr-Ad and only 21% (620) (95% CI, 19.16%–22.06%) were Pr-Car. 30% (889) (95% CI, 27.92%–31.18%) were Unp–Car, and 10% (310) (95% CI, 9.22%– 11.4%) Unp-Ad. 48% of patients with a single reason for attendance were Pr-Ad (577) (95% CI, 44.25%–52.05). Teaching centres and computerised ones had less Pr-Ad load. Pr-Ad consultations increased with patient´s age and with case-load.ConclusionsAlmost 40% of the reasons for consultation are Pr-Ad, which implies inadequate clinical management. An intervention is needed to free up medical time consumed by bureaucratic questions, so that this time can be devoted fully to health-care task

Using manure as fertilizer for maize could improve sustainability of milk production

This study evaluated the effect of organic or chemical fertilization of maize on cow performance, economic outcomes, and greenhouse gas emission. Each type of maize silage according its different fertilization was used in two rations offered to two different groups of nine Friesian-Holstein cows throughout 4 months. The production cost of the maize silage was 8.8% lower for organic than for chemical fertilization. Both silages had similar nutritive value, except a higher concentration of starch in maize with organic fertilization, which allowed a reduction in the proportion of concentrate in the ration, saving 25.3 eurocents per cow in the daily ration, generating a positive balance of 21.8 eurocents per cow and day. The milk yield and composition were unaffected depending on the type of fertilization, whereas the estimation of CH4 and N2O emissions with chemical fertilization was higher than emissions with organic fertilization. As a result, it is possible to increase the sustainability and profitability of dairy production with reuse and recycling of manure

Results of salt intake restriction monitored with the new sodium control biosensor

Adherence to a low sodium (Na) diet is crucial in patients under hemodialysis, as it improves cardiovascular outcomes and reduces thirst and interdialytic weight gain. Recommended salt intake is lower than 5 g/day. The new 6008 CareSystem monitors incorporate a Na module that offers the advantage of estimating patients' salt intake. The objective of this study was to evaluate the effect of dietary Na restriction for 1 week, monitored with the Na biosensor.A prospective study was conducted in 48 patients who maintained their usual dialysis parameters and were dialyzed with a 6008 CareSystem monitor with activation of the Na module. Total Na balance, pre/postdialysis weight, serum Na (sNa), changes in pre- to post-dialysis sNa (ΔsNa), diffusive balance, and systolic and diastolic blood pressure were compared twice, once after 1 week of patients' usual Na diet and again after another week with more restricted Na intake.Restricted Na intake increased the percentage of patients on a low-sodium diet (<85 Na mmol/day) from 8% to 44%. Average daily Na intake decreased from 149 ± 54 to 95 ± 49 mmol and interdialytic weight gain was reduced by 460 ± 484 g per session. More restricted Na intake also decreased pre-dialysis sNa and increased both intradialytic diffusive balance and ΔsNa. In hypertensive patients, reducing daily sodium by more than 3 g Na/day lowered their systolic blood pressure.The new Na module allowed objective monitoring of Na intake, which in turn could permit more precise personalized dietary recommendations in patients under hemodialysis.S.

Defibrotide inhibits donor leucocyte-endothelial interactions and protects against acute graft-versus-host disease

Altres ajuts: This study has been funded by Josep Carreras Leukaemia Foundation (Grant 11R/2016 and 03R/2019).Allogeneic hematopoietic stem cell transplantation (allo-HCT) is an effective therapy for the treatment of high-risk haematological malignant disorders and other life-threatening haematological and genetic diseases. Acute graft-versus-host disease (aGvHD) remains the most frequent cause of non-relapse mortality following allo-HCT and limits its extensive clinical application. Current pharmacologic agents used for prophylaxis and treatment of aGvHD are not uniformly successful and have serious secondary side effects. Therefore, more effective and safe prophylaxis and therapy for aGvHD are an unmet clinical need. Defibrotide is a multi-target drug successfully employed for prophylaxis and treatment of veno-occlusive disease/sinusoidal obstruction syndrome. Recent preliminary clinical data have suggested some efficacy of defibrotide in the prevention of aGvHD after allo-HCT. Using a fully MHC-mismatched murine model of allo-HCT, we report here that defibrotide, either in prophylaxis or treatment, is effective in preventing T cell and neutrophil infiltration and aGvHD-associated tissue injury, thus reducing aGvHD incidence and severity, with significantly improved survival after allo-HCT. Moreover, we performed in vitro mechanistic studies using human cells revealing that defibrotide inhibits leucocyte-endothelial interactions by down-regulating expression of key endothelial adhesion molecules involved in leucocyte trafficking. Together, these findings provide evidence that defibrotide may represent an effective and safe clinical alternative for both prophylaxis and treatment of aGvHD after allo-HCT, paving the way for new therapeutic approaches
