Efectividad del aceite de canola en dietas de cerdos para mejorar el perfil lipídico de la carne

The objective of this study was to determine the maximum level of inclusion of canola oil (CO) in diets for finishing pigs, to increase the content of oleic acid and unsaturated fatty acids and improve the Ω6:Ω3 ratio in meat, without affecting the productive performance, carcass characteristics and physicochemical characteristics of the meat. The treatments were: the gradual substitution of soybean oil (6 %) for CO in diets for pigs at finishing stage I and II (0, 2, 4 and 6 % of CO). The experimental units were 48 castrated pigs with initial live weight of 50.00 ± 4.5 kg, evaluated for four weeks at each stage. With the data obtained, an ANOVA was performed, and linear or quadratic trends were detected (P≤0.10). At finishing stage I, the average daily gain decreased with the inclusion of 2 % of CO, although the incorporation of 2 and 4 % of CO had no effect. At finishing stage II, a level between 2-4 % of CO reduced average daily feed intake and improved feed conversion (P≤0.05). The addition of CO did not modify the characteristics of the carcass and did not affect the physicochemical characteristics of the meat (P≥0.10). CO in the diet increased the concentration of monounsaturated fatty acids (MUFAs) and oleic acid (P≤0.05); it reduced linoleic acid (P≤0.03), polyunsaturated fatty acids (P≤0.07) and the Ω6:Ω3 ratio (P≤0.01). In conclusion, the addition of CO (2-6 %) in the diet of finishing pigs gradually increases the content of oleic acid and MUFAs, in addition, it improves the Ω6:Ω3 ratio in pork, without affecting the productive variables and the quality of the meat.El objetivo de este estudio fue determinar el nivel máximo de inclusión de aceite de canola (AC) en dietas para cerdos en finalización, para incrementar el contenido de ácido oleico y ácidos grasos insaturados y mejorar la relación Ω6: Ω3 en la carne, sin afectar el comportamiento productivo, características de la canal y fisicoquímicas de la carne. Los tratamientos fueron: la sustitución gradual de aceite de soya (6%) por AC en dietas para cerdos en etapa de finalización I y II (0, 2, 4 y 6% de AC). Las unidades experimentales fueron 48 cerdos machos castrados con peso vivo inicial de 50.00 ± 4.5 kg, evaluados durante cuatro semanas en cada etapa. Con los datos obtenidos se realizó un ANDEVA y se detectaron tendencias lineales o cuadráticas (P≤0.10). En finalización I la ganancia de peso disminuyó con la inclusión de 2% de AC, aunque la incorporación de 2 y 4% de AC no tuvo efecto. En finalización II, un nivel entre 2-4% de AC redujo el consumo de alimento y mejoró la conversión alimenticia (P≤0.05). La adición de AC no modificó las características de la canal y no afectó las características fisicoquímicas de la carne (P≥0.10). El AC en la dieta aumentó la concentración de ácidos grasos monoinsaturados (AGMI) y ácido oleico (P≤0.05); redujo el ácido linoleico (P≤0.03), ácidos grasos poliinsaturados (P≤0.07) y la relación Ω6:Ω3 (P≤0.01). En conclusión, la adición de AC (2-6%) en la dieta de cerdos en finalización incrementa gradualmente el contenido de ácido oleico y de AGMI, además, mejora la relación Ω6:Ω3 en la carne de cerdo, sin afectar las variables productivas y la calidad de la carne

SARS-CoV-2 viral load in nasopharyngeal swabs is not an independent predictor of unfavorable outcome

The aim was to assess the ability of nasopharyngeal SARS-CoV-2 viral load at first patient’s hospital evaluation to predict unfavorable outcomes. We conducted a prospective cohort study including 321 adult patients with confirmed COVID-19 through RT-PCR in nasopharyngeal swabs. Quantitative Synthetic SARS-CoV-2 RNA cycle threshold values were used to calculate the viral load in log10 copies/mL. Disease severity at the end of follow up was categorized into mild, moderate, and severe. Primary endpoint was a composite of intensive care unit (ICU) admission and/or death (n = 85, 26.4%). Univariable and multivariable logistic regression analyses were performed. Nasopharyngeal SARS-CoV-2 viral load over the second quartile (≥ 7.35 log10 copies/mL, p = 0.003) and second tertile (≥ 8.27 log10 copies/mL, p = 0.01) were associated to unfavorable outcome in the unadjusted logistic regression analysis. However, in the final multivariable analysis, viral load was not independently associated with an unfavorable outcome. Five predictors were independently associated with increased odds of ICU admission and/or death: age ≥ 70 years, SpO2, neutrophils > 7.5 × 103/µL, lactate dehydrogenase ≥ 300 U/L, and C-reactive protein ≥ 100 mg/L. In summary, nasopharyngeal SARS-CoV-2 viral load on admission is generally high in patients with COVID-19, regardless of illness severity, but it cannot be used as an independent predictor of unfavorable clinical outcome

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Comparison of the new risk prediction model (HCM Risk-SCD) and classic risk factors for sudden death in patients with hypertrophic cardiomyopathy and defibrillator.

Hypertrophic cardiomyopathy is one of the main causes of sudden death in young people. Recent clinical practice guidelines include a risk prediction model for sudden death (HCM Risk-SCD), which facilitates the decision of whether to implant a defibrillator. The aim of our study was to ascertain the percentage of events in our series of primary prevention implantable cardioverter-defibrillator recipients with hypertrophic cardiomyopathy and whether HCM Risk-SCD predicts the onset of arrhythmic events. This was an observational, retrospective cohort study, which included 48 primary prevention defibrillator recipient patients with HCM. We compiled their demographic and clinical characteristics, estimated 5-year risk using HCM Risk-SCD, and collected the documentation on arrhythmias during follow-up. The majority was male (66.7%) and mean age at implantation was 44.44 ± 14.46 years. Non-sustained ventricular tachycardia was the most prevalent risk factor (66.67%), followed by a family history of sudden death (47.92%). Mean HCM Risk-SCD was 6.15 ± 5.01%. HCM Risk-SCD was the only factor independently associated with the onset of ventricular tachyarrhythmia, above any other classic risk factor or association [odds ratio = 1.46 (95% confidence interval 1.051-2.013); P = 0.02]. None of the 11 patients estimated as low risk using HCM Risk-SCD suffered any appropriate events (P During an average follow-up of 4 years, 16.67% presented appropriate events (4.16%/year). HCM Risk-SCD predicted the onset of events more suitably than classic risk factors

Chapter Interoperability in a Heterogeneous Team of Search and Rescue Robots

Search and rescue missions are complex operations. A disaster scenario is generally unstructured, time‐varying and unpredictable. This poses several challenges for the successful deployment of unmanned technology. The variety of operational scenarios and tasks lead to the need for multiple robots of different types, domains and sizes. A priori planning of the optimal set of assets to be deployed and the definition of their mission objectives are generally not feasible as information only becomes available during mission. The ICARUS project responds to this challenge by developing a heterogeneous team composed by different and complementary robots, dynamically cooperating as an interoperable team. This chapter describes our approach to multi‐robot interoperability, understood as the ability of multiple robots to operate together, in synergy, enabling multiple teams to share data, intelligence and resources, which is the ultimate objective of ICARUS project. It also includes the analysis of the relevant standardization initiatives in multi‐robot multi‐domain systems, our implementation of an interoperability framework and several examples of multi‐robot cooperation of the ICARUS robots in realistic search and rescue missions
