Application of enzyme matrix values for energy and nutrients to a wheat-corn-soybean meal-based broiler diet supplemented with a novel phytase, with or without a xylanase-ß-glucanase, achieved a production benefit over a nutritionally adequate unsupplemented diet.

The effect of applying an energy and nutrient matrix to a wheat-corn-soybean meal-based diet supplemented with a novel consensus bacterial 6-phytase variant (PhyG) and xylanase-ß-glucanase on growth performance, bone mineralization, carcass weights, feed costs, and carbon footprint was evaluated. A randomized complete block design (3,300 Ross 308 mixed-sex birds; 60 pens, 12 pens per treatment) tested 5 treatments: 1) a positive control diet (PC), containing 0.92, 0.84, 0.71% Ca and 0.43, 0.38, 0.30% digestible P during 1 to 10, 11 to 21, and 22 to 32 d of age, respectively; 2) a negative control reduced in Ca, digestible P, digestible AA, ME, and Na by phase based on the PhyG dosing regimen (NC1); 3) NC1 supplemented with PhyG at 2,000, 1,500, and 1,000 FTU/kg by phase (NC1+PhyG); 4) as NC1 but additionally reduced in ME (NC2); and 5) NC2 supplemented with PhyG as in 3) plus 1,220 U/kg of xylanase and 152 U/kg of ß-glucanase (NC2+PhyG+XB). Final (d 32) BW, overall (0-32 d of age) ADFI, FCR, d 10 and 32 tibia ash and carcass part weights were reduced or impaired (P < 0.05) in NC1 and NC2 vs. PC (d 32 BW -477 g/bird (23.4%) and -422 g/bird (20.7%), respectively). Growth performance (all measures, all phases) was improved and tibia ash (at 10 and 32 d of age), total carcass thigh, breast and leg weights were increased (P < 0.05) in NC1+PhyG vs. NC1, and NC2+PhyG+XB vs. NC2. Overall growth performance outcomes in NC1+PhyG and NC2+PhyG+XB were not different (P > 0.05) from the PC. Total feed cost and carbon footprint per kilogram BW gain (BWG) were reduced (P < 0.05) vs. PC in NC2+PhyG+XB [-0.052 € and -376 g CO2 eq./kg BWG, respectively] and NC1+PhyG [-0.038 € and -260 g CO2 eq./kg BWG, respectively]. The results validated the nutrient matrices in the test diets and highlighted a potential feed cost and environmental sustainability benefit which was greatest when the enzymes were applied in combination.

¿Es posible predecir la presencia de cáncer colorrectal en el análisis sanguíneo? Método de aproximación probabilística / Is it possible to predict the presence of colorectal cancer in a blood test? A probabilistic approach method

Introducción: la valoración del estado de inmunovigilancia (capacidad del organismo para evitar el desarrollo de neoplasias) en el análisis sanguíneo presenta connotaciones pronósticas de interés en el cáncer colorrectal. Evaluamos un posible carácter predictivo de la enfermedad en el análisis sanguíneo y su cuantificación mediante el diseño de un índice de interacción matemático entre varios parámetros sanguíneos, con capacidad predictiva probabilística de presencia de la enfermedad. Método: estudio casos y controles de análisis comparativo de la distribución de parámetros sanguíneos, sobre 266 pacientes con cáncer colorrectal y 266 pacientes sanos, durante el periodo comprendido entre 2009-2013. Resultados: los sujetos con cáncer colorrectal presentaron, con respecto a los controles, diferencias estadísticamente significativas (p < 0,05) en los niveles de plaquetas, fibrinógeno, leucocitos totales, neutrófilos, índices de inmunovigilancia sistémica (ratio neutrófilo/linfocito y ratio plaqueta/linfocito), hemoglobina, hematocrito y eosinófilos. Estas diferencias permitieron el diseño de un perfil analítico sanguíneo de riesgo de enfermedad, cuantificable mediante la aplicación de una fórmula matemática con capacidad de identificación probabilística de los sujetos con mayor riesgo de presencia de enfermedad (área bajo la curva del espacio ROC = 0,85). Conclusiones: Ante la posible existencia de un carácter predictivo de presencia de cáncer colorrectal en el análisis sanguíneo, mostramos que es posible su cuantificación mediante el diseño de un índice de interacción entre varios parámetros sanguíneos. El diseño y desarrollo de índices de interacción entre parámetros sanguíneos constituye una línea de investigación de interés para el desarrollo y mejora de programas de cribado de la enfermedad (AU)

Introduction: The assessment of the state of immunosurveillance (the ability of the organism to prevent the development of neoplasias) in the blood has prognostic implications of interest in colorectal cancer. We evaluated and quantified a possible predictive character of the disease in a blood test using a mathematical interaction index of several blood parameters. The predictive capacity of the index to detect colorectal cancer was also assessed. Methods: We performed a retrospective case-control study of a comparative analysis of the distribution of blood parameters in 266 patients with colorectal cancer and 266 healthy patients during the period from 2009 to 2013. Results: Statistically significant differences (p < 0.05) were observed between patients with colorectal cancer and the control group in terms of platelet counts, fibrinogen, total leukocytes, neutrophils, systemic immunovigilance indexes (neutrophil to lymphocyte ratio and platelet to lymphocyte ratio), hemoglobin, hematocrit and eosinophil levels. These differences allowed the design of a blood analytical profile that calculates the risk of colorectal cancer. This risk profile can be quantified via a mathematical formula with a probabilistic capacity to identify patients with the highest risk of the presence of colorectal cancer (area under the ROC curve = 0.85). Conclusions: We showed that a colorectal cancer predictive character exists in blood which can be quantified by an interaction index of several blood parameters. The design and development of interaction indexes of blood parameters constitutes an interesting research line for the development and improvement of programs for the screening of colorectal cancer (AU)

Effects and consequences of caring for persons with heart failure: (ECCUPENIC study) a nested case-control study.

AIM: Primary: To report a research protocol to analyse the relationship between the degree of heart failure and the health-related quality of life of patients and their family caregivers. Secondary: To identify the characteristics of heart failure patients and their caregivers and the association between these characteristics and hospital admissions. Moreover, to conduct a longitudinal analysis of the relationship between patients' and that of their family caregivers. BACKGROUND: As heart failure progresses, it reduces the patient's quality of life and progressive functional deterioration requires hospital admission and the provision of healthcare resources. The availability of a family caregiver is a key element in addressing and managing this healthcare problem and some research results have associated this factor with the prognosis for heart failure. DESIGN: Multicentre cohort nested case-control study. METHODS: Exploratory analysis: Descriptive statistics, measures of central tendency and dispersion or percentages. Bivariate analysis: Using Student's t-test and chi-square test, anova and non-parametric tests. Survival analysis: Kaplan-Meier curves. Multivariate analysis: Cox's proportional hazards model. All calculations performed with an alpha level of 0·05. DISCUSSION: Lack of family support for patients with HF or greater duration of care is associated with more hospitalizations and increased depression among caregivers. Further longitudinal studies with a large population sample are required.

[CUN-BAE formula and biochemical factors as predictive markers of obesity and cardiovascular disease in patients before and after sleeve gastrectomy]. / Fórmula CUN-BAE y factores bioquímicos como marcadores predictivos de obesidad y enfermedad cardiovascular en pacientes pre y post gastrectomía vertical.

INTRODUCTION: Body Mass Index (BMI) is one of the most used parameters in bariatric surgery. However, it does not discriminate the weight associated with adiposity. CUN-BAE formula is an equation that calculates Body Fat Percentage or adiposity, based on easily available values (age, sex and BMI). With this new classification many of the subjects that was considered normal weight or overweight (BMI ≤30 kg/m2) really have a higher adiposity and they have comorbidities associated with obesity. The objective of this study is to evaluate the adiposity by formula CUN-BAE as a predictive marker of cardiovascular risk in morbidly obese patients before and after sleeve gastrectomy. MATERIAL AND METHODS: We performed a retrospective observational study of women that were intervened with sleeve gastrectomy, between 2007 and 2012 at the Universitary General Hospital of Elche. The adiposity was calculated by formula CUN-BAE preoperatively and 12 months after surgery. These values were correlated with different metabolic and cardiovascular risk parameters. RESULTS: 50 women were studied. Preoperatively, the mean BMI was 50.4 ± 7 kg/m2 and adiposity 54.8 ± 3%. One year after surgery, the mean BMI was 27.7 ± 3 and adiposity 39.4 ± 4%. The adiposity was significantly correlated with 3 biochemical factors associated with increased cardiovascular risk (cortisol, vitamin D and ratio TG/HDL). CONCLUSION: Adiposity, according to the formula CUNBAE, and biochemical analysis of predictive factors of obesity together represent useful tools for assessing the risk of cardiovascular disease after sleeve gastrectomy.

Introducción: Introducción: El Índice de Masa Corporal (IMC) es uno de los parámetros más utilizados en cirugía bariátrica. Sin embargo, no discrimina el peso asociado a adiposidad. La fórmula CUN-BAE es una ecuación que permite calcular el Porcentaje de Grasa Corporal (PGC) o adiposidad, basándose en valores fáciles de disponer (edad, sexo e IMC). Con esta nueva clasificación muchos de los sujetos considerados con normopeso o sobrepeso (IMC ≤30 kg/m2) en realidad tienen un PGC alto y presentan comorbilidades asociadas a la obesidad. El objetivo de este estudio es evaluar PGC cuantificado mediante fórmula CUN-BAE como marcador predictivo de riesgo cardiovascular en pacientes obesos mórbidos, antes y después de ser sometidos a Gastrectomía Vertical (GV). Material y métodos: Realizamos un estudio observacional retrospectivo de mujeres intervenidas de GV entre 2007 y 2012 en el Hospital General Universitario de Elche, calculando el PGC mediante la fórmula CUN-BAE de forma preoperatoria y 12 meses tras la intervención. Se correlacionaron estos valores con diferentes parámetros metabólicos y de riesgo cardiovascular. Resultados: Se estudiaron 50 mujeres. Preoperatoriamente, el IMC medio de 50,4 ± 7,4 kg/m2 y PGC del 54,8 ± 3%. Al año de la intervención, el IMC medio era de 27,7 ± 2,6 y el PGC 39,4 ± 3,7%. La PGC se correlacionó significativamente con 3 factores bioquímicos asociados con mayor riesgo cardiovascular (cortisol, vitamina D y cociente TG/HDL). Conclusión: la adiposidad, según la fórmula CUN-BAE, y el análisis de factores bioquímicos predictivos de obesidad, de forma conjunta suponen herramientas útiles para valorar el riesgo de enfermedad cardiovascular, después de GV.

[Acute renal failure and chronic diarrhea: McKittrick-Wheelock syndrome]. / Insuficiencia renal aguda y diarrea crónica: síndrome de McKittrick-Wheelock.

In 1954, McKittrick and Wheelock described for the first time a syndrome presenting chronic lost of fluid and electrolytes secondary to chronic diarrhea, associated to large rectal villous adenomas. We report a case of a 75-year-old female who presented chronic diarrhea (3 to 4 depositions per day in the last year), accompanied by acute renal failure. In the rectal tact, we objective the presence of a mass of soft consistency with an irregular surface, occupying approximately two thirds of the circumference, at about 3 cm from the anal margin. It was confirmed by the colonoscopy and the patology was informed as villous adenoma, producing chronic diarrhea or McKittrick-Wheelock syndrome. We decide the surgical approach after the normalization of patient's general status and a proctectomy with coloanal anastomosis was performed. We conclude that we must think about this syndrome in aged patients with chronic diarrhea, alterations of the electrolyte balance and presence of renal failure. Surgery treatment after the replacement of water and electrolytes is the unique curative treatment. The absence of this can cause the death of these patients.

Right trisectionectomy of the liver for intrahepatic cholangiocarcinoma with bile duct invasion in a Jehovah's Witness.

Intrahepatic cholangiocarcinoma (ICC) is well known to have a very poor prognosis. Aggressive surgical strategies in the treatment of ICC, including major hepatectomy, have been reported to afford patients the best chance for significant survival. Recent advancements in surgical techniques concerning live donor liver transplantation have dramatically improved the results of major hepatectomy. However, surgical treatment of biliary malignancy is complex and is known to increase the likelihood of blood transfusion. We describe a Jehovah's Witness patient with ICC and concomitant bile duct invasion who had a successful right trisectionectomy with bile duct resection, lymph node dissection, and Rouxen-Y hepatico-jejunostomy without blood transfusion. A multidisciplinary preparation was crucial in obtaining this positive outcome. Importantly, bloodless liver transection techniques with inflow clamping, meticulous dissection, and hemostasis should be utilized for major hepatectomy in a Jehovah's Witness. The success of this case may alert clinicians to consider a hepatectomy as a possible option in the treatment of ICC in a Jehovah's Witness.
