[ASPEN-FELANPE Clinical Guidelines: Nutrition Support of Adult Patients with Enterocutaneous Fistula]. / Guías Clínicas ASPEN-FELANPE: Terapia Nutricional en Pacientes Adultos con Fístulas Enterocutáneas.

INTRODUCTION: Background: the management of patients with enterocutaneous fistula (ECF) requires an interdisciplinary approach and poses a significant challenge to surgeons, gastroenterologists, intensivists, wound/stoma care specialists, and nutrition support clinicians. Available guidelines for optimizing nutritional status in these patients are often vague, based on limited and dated clinical studies, and typically rely on individual or institutional experience. Specific nutrient requirements, appropriate route of feeding, role of immune-enhancing nutrients, and use of somatostatin analogs in the management of patients with ECF remain a challenge for the clinician. The purpose of this clinical guideline is to develop recommendations for the nutritional care of adult patients with ECF. Methods: a systematic review of the best available evidence to answer a series of questions regarding clinical management of adults with ECF was undertaken and evaluated using concepts adopted from the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group. An anonymous consensus process was used to develop the clinical guideline recommendations prior to peer review and approval by the A.S.P.E.N. and FELANPE Board of Directors. Questions: in adult patients with enterocutaneous fistula: 1) What factors best describe nutritional status? 2) What is the preferred route of nutritional therapy (oral diet, EN or PN)? 3) What protein and energy intake provide best clinical outcomes? 4) Is fistuloclysis associated with better outcomes than standard care? 5) Are immune-enhancing nutrients associated with better outcomes? 6) Does the use of somatostatin provide better outcomes than standard medical therapy? 7) When is home parenteral nutrition support indicated?

INTRODUCCIÓN: Introducción: el manejo de las fístulas enterocutáneas (FEC) es un reto que requiere enfoque interdisciplinario y plantea un desafío importante. Las guías para optimizar el estado nutricional en estos pacientes están basadas en estudios que dependen de la experiencia individual y, ocasionalmente, institucional; que se focalizan en el tratamiento integral de las FEC, centrándose en el manejo médico y quirúrgico, mientras que la terapia nutricional se revisa solo superficialmente. Los requerimientos nutricionales, vía de administración, uso de inmunonutrición y de análogos de la somatostatina en el tratamiento de estos pacientes no están bien definidos. El objetivo de esta guía es desarrollar recomendaciones específicas para la terapia nutricional de los pacientes adultos con FEC. Método: revisión sistemática de la mejor evidencia disponible para responder a una serie de preguntas sobre la terapia nutricional de los adultos con FEC, evaluada utilizando la metodología GRADE. Se utilizó un proceso de consenso anónimo para desarrollar las recomendaciones de la guía clínica antes de la revisión por pares y la aprobación por las Juntas Directivas de ASPEN y FELANPE. Preguntas: 1) ¿Qué factores describen mejor el estado nutricional de los adultos con FEC? 2) ¿Cuál es la mejor vía para administrar la terapia nutricional (oral, nutrición enteral o parenteral)? 3) ¿Qué aporte energético y proteico proporciona mejores resultados clínicos? 4) ¿El uso de la fistuloclisis se asocia a mejores resultados? 5) ¿Las fórmulas inmunomoduladoras se asocian a mejores resultados? 6) ¿El uso de la somatostatina proporciona mejores resultados? 7) ¿Cuándo está indicada la terapia nutricional parenteral domiciliaria?

ASPEN-FELANPE Clinical Guidelines.

BACKGROUND: The management of patients with enterocutaneous fistula (ECF) requires an interdisciplinary approach and poses a significant challenge to physicians, wound/stoma care specialists, dietitians, pharmacists, and other nutrition clinicians. Guidelines for optimizing nutrition status in these patients are often vague, based on limited and dated clinical studies, and typically rely on individual institutional or clinician experience. Specific nutrient requirements, appropriate route of feeding, role of immune-enhancing formulas, and use of somatostatin analogues in the management of patients with ECF are not well defined. The purpose of this clinical guideline is to develop recommendations for the nutrition care of adult patients with ECF. METHODS: A systematic review of the best available evidence to answer a series of questions regarding clinical management of adults with ECF was undertaken and evaluated using concepts adopted from the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group. An anonymous consensus process was used to develop the clinical guideline recommendations prior to peer review and approval by the ASPEN Board of Directors and by FELANPE. QUESTIONS: In adult patients with enterocutaneous fistula: (1) What factors best describe nutrition status? (2) What is the preferred route of nutrition therapy (oral diet, enteral nutrition, or parenteral nutrition)? (3) What protein and energy intake provide best clinical outcomes? (4) Is fistuloclysis associated with better outcomes than standard care? (5) Are immune-enhancing formulas associated with better outcomes than standard formulas? (6) Does the use of somatostatin or somatostatin analogue provide better outcomes than standard medical therapy? (7) When is home parenteral nutrition support indicated?

[Not Available]. / Nutritional assessment of hospitalized patients in Latin America: association with prognostic variables. The ENHOLA study.

BACKGROUND AND AIM: The prevalence of hospital malnutrition (HM) is variable, explained by the variability of patients, the nutritional evaluation method used among others. The aim is to determine the frequency of malnutrition in hospitals in Latin America, and estimate its association with mortality and length of hospital stay. METHODS: This is an analytical, observational cohort study that included 7,973 patients of both genders, 18 and older, who provided their consent. The survey was administered during the first three days of admission. The nutritional status was estimated using Subjective Global Assessment (SGA) and the Nutrition Risk Screening (NRS), body mass index (BMI), percentage of change of weight (PCW) and co-morbidities. Serum albumin was obtained from the clinical chart. Length of stay (LOS) and the survival status at discharge (dead or alive) were also recorded. RESULTS: By SGA: 10.9% had severe malnutrition and 34% moderate malnutrition. By NRS: 36.9% had nutritional risk. Univariate analysis showed that NRS score and serum albumin were prognostic factors for mortality: NRS 3-4 (OR: 2.3, 95% CI: 1.9-2.8), NRS 5-7 (OR: 5.8, 95% CI: 4.9-6.9), serum albumin < 2.5 g/dl, (OR: 2.9, 95% CI: 2.2-3.8). These results were consistent and similar to a multivariate analysis. Both NRS and serum albumin were also independently and clinically associated to LOS. CONCLUSIONS: The prevalence of hospital malnutrition in Latin America is high. Our results show that screening with NRS and serum albumin can identify hospital malnutrition as well as providing clinically relevant prognostic value.

Addressing Disease-Related Malnutrition in Healthcare: A Latin American Perspective.

Alarmingly high rates of disease-related malnutrition have persisted in hospitals of both emerging and industrialized nations over the past 2 decades, despite marked advances in medical care over this same interval. In Latin American hospitals, the numbers are particularly striking; disease-related malnutrition has been reported in nearly 50% of adult patients in Argentina, Brazil, Chile, Costa Rica, Cuba, Dominican Republic, Ecuador, Mexico, Panama, Paraguay, Peru, Puerto Rico, Venezuela, and Uruguay. The tolls of disease-related malnutrition are high in both human and financial terms-increased infectious complications, higher incidence of pressure ulcers, longer hospital stays, more frequent readmissions, greater costs of care, and increased risk of death. In an effort to draw attention to malnutrition in Latin American healthcare, a feedM.E. Latin American Study Group was formed to extend the reach and support the educational efforts of the feedM.E. Global Study Group. In this article, the feedM.E. Latin American Study Group shows that malnutrition incurs excessive costs to the healthcare systems, and the study group also presents evidence of how appropriate nutrition care can improve patients' clinical outcomes and lower healthcare costs. To achieve the benefits of nutrition for health throughout Latin America, the article presents feedM.E.'s simple and effective Nutrition Care Pathway in English and Spanish as a way to facilitate its use.

[Laparoscopic versus open surgery for colorectal cancer. A comparative study]. / Estudio comparativo entre cirugía laparoscópica y cirugía abierta en cáncer colorrectal.

BACKGROUND: Laparoscopic surgery for colorectal cancer is currently accepted and widespread worldwide. However, according tol the surgical experience on this approach, surgical and short-term oncologic results may vary. Studies comparing laparoscopic vs. open surgery in our population are scarce. OBJECTIVE: To determine the superiority of the laparoscopic vs. open technique for colorectal cancer surgery. METHODS: This retrospective and comparative study collected data from patients operated on for colorectal cancer between 1999 and 2011 at the Angeles Lomas Hospital, Mexico. RESULTS: A total of 82 patients were included in this study; 47 were operated through an open approach and 35 laparoscopically. Mean operative time was significantly lower in the open approach group (p= 0.008). There were no significant difference between both techniques for intraoperative bleeding (p= 0.3980), number of lymph nodes (p= 0.27), time to initiate oral feeding (p= 0.31), hospital stay (p= 0.12), and postoperative pain (p= 0.19). Procedure-related complications rate and type were not significantly different in both groups (p= 0.44). Patients operated laparoscopically required significantly less analgesic drugs (p= 0.04) and less need for epidural postoperative analgesia (p= 0.01). CONCLUSIONS: Laparoscopic approach is as safe as the traditional open approach for colorectal cancer. Early oncological and surgical results confirm its suitability according to this indication.

Antecedentes: la cirugía laparoscópica para tratar pacientes con cáncer colorrectal ha sido ampliamente aceptada y difundida en todo el mundo. Sin embargo, dependiendo de la experiencia en este abordaje los resultados quirúrgicos y oncológicos a corto plazo pueden variar. En nuestra población existen pocos estudios que comparan los resultados de esta técnica con los de la cirugía abierta. Objetivos: determinar la superioridad de la técnica laparoscópica o abierta en cirugía de cáncer colorrectal. Material y métodos: estudio retrospectivo y comparativo de pacientes operados con técnica abierta o laparoscópica por cáncer de colon y recto entre 1999 y 2011 en nuestro centro. Resultados: se incluyeron 47 pacientes intervenidos de manera convencional y 35 por laparoscopia. El tiempo operatorio fue menor en el grupo de cirugía abierta (p= 0.008). No se encontraron diferencias en: sangrado intraoperatorio (p= 0.3980), número de ganglios resecados (p= 0.27), inicio de la vía oral (p= 0.31), tiempo de estancia hospitalaria (p= 0.12), y dolor referido por el paciente (p= 0.19). En el grupo de cirugía laparoscópica se requirieron menos dosis de analgésicos (p= 0.04) y menor necesidad de catéter epidural para analgesia postoperatoria (p= 0.01). Las tasas de morbilidad (p= 0.44) y mortalidad (p= 0.39) fueron similares en ambos grupos. Conclusiones: la cirugía laparoscópica es equiparable a la técnica abierta en cuanto a estándares oncológicos y resultados técnicos. Este trabajo demuestra que en nuestro hospital la cirugía laparoscópica en pacientes con cáncer de colon y recto es tan segura como la cirugía abierta.

Introducción y objetivo: la prevalencia de la malnutrición hospitalaria (MH) es variable y puede explicarse por la variabilidad de los pacientes, el método de evaluación nutricional entre otros. El propósito de esta investigación es determinar la frecuencia de malnutrición en hospitales de Latinoamérica y estimar su asociación con mortalidad y estancia hospitalaria. Métodos: es un estudio analítico, observacional de cohorte que incluyó a 7.973 pacientes de ambos géneros, mayores de 18 años y que estuvieron de acuerdo en participar en el estudio. La evaluación fue aplicada durante los primeros tres días de admisión al hospital. El estado nutricional fue estimado usando la evaluación global subjetiva (SGA) y el score de riesgo nutricional (NRS-2002). Se evaluó el índice de masa corporal (IMC), el porcentaje de cambio de peso (PCW) y las comorbilidades. La albúmina sérica se obtuvo del expediente clínico. La estancia hospitalaria (LOS) y las condiciones del egreso (vivo o muerto) fueron también registrados. Resultados: por SGA: 10,9% tuvieron malnutrición severa y 34% malnutrición moderada. Por NRS: 36,9% tuvieron riesgo nutricional. El análisis univariado mostró que el NRS y la albúmina sérica fueron factores pronósticos de mortalidad: NRS 3-4 (OR: 2,3, 95%CI: 1,9-2,8), NRS 5-7 (OR: 5,8, 95% CI: 4,9-6,9), albúmina sérica < 2,5 g/dl, (OR: 2,9, 95% CI: 2,2-3,8); estos resultados fueron coherentes y similares al análisis multivariado. Tanto el NRS y como la albúmina sérica fueron también independientemente y clínicamente asociados a la estancia hospitalaria prolongada. Conclusión: la prevalencia de malnutrición hospitalaria en Latinoamérica es alta. Nuestros resultados muestran que el tamizaje con NRS y la albúmina sérica inicial pueden identificar la malnutrición hospitalaria, así como proporcionar un valor clínico relevante (AU)
