          Abstract

          Resumen Introducción: la intervención nutricia se ha convertido en un punto crítico para lograr la disminución de la morbimortalidad perioperatoria en el paciente oncológico. Existen distintos factores que jugarán un papel fundamental en la evolución y el pronóstico de esta patología, siendo el estado de nutrición y la dieta una piedra angular en estos aspectos. Objetivos: evaluar el efecto perioperatorio de la proteína aislada de suero de leche (WPI) y el caseinato de calcio (CaCNT) en pacientes oncológicos sometidos a cirugía electiva. Métodos: ensayo clínico controlado aleatorizado con tres grupos: grupo control (n = 15), que consistió en manejo convencional por parte de los servicios de cirugía oncológica, y dos grupos de intervención, uno con suplementación de caseinato de calcio (n = 15) y otro con suplementación con proteína aislada de suero de leche (n = 15) durante seis semanas de forma perioperatoria. Se evaluaron en tiempos preoperatorio y postoperatorio la fuerza de prensión de mano, la caminata de seis minutos y la composición corporal. Resultados: aquellos que fueron suplementados con WPI mantuvieron la fuerza de prensión y mostraron menor cantidad de agua extracelular (p < 0,02); se mostró un incremento en la masa visceral (p < 0,02). Finalmente, se encontró correlación con variables asociadas a la composición corporal y variables de evolución del paciente en comparación con el grupo control. Conclusiones: la suplementación nutricional requiere ser abordada desde el punto de vista funcional y metabólico para identificar factores que impacten favorablemente, así como la distinción entre carcinoma y el tipo de suplementación a implementar.

          Abstract Introduction: the nutritional intervention has become a critical point to achieve the reduction of perioperative morbidity and mortality in cancer patients. There are different factors that will play a fundamental role in the evolution and prognosis of this pathology, being the state of nutrition and diet a cornerstone in these aspects. Objective: to evaluate the perioperative effect of whey protein isolate (WPI) and calcium caseinate (CaCNT) in cancer patients undergoing elective surgery. Methods: randomized controlled clinical trial with three groups: the control group (n = 15), consisting in conventional management by the oncology surgery services, and two intervention groups, one with calcium caseinate supplementation (n = 15) and another one with whey protein isolate supplementation (n = 15) for six weeks perioperatively. Handgrip strength, six-minute walk, and body composition were assessed pre and postoperatively. Results: those who were supplemented with WPI maintained their handgrip strength and showed less extracellular water (p < 0.02); also an increase in visceral mass was shown (p < 0.02). Finally, a correlation was found with variables associated with body composition and patient evolution when compared to the control group. Conclusions: nutritional supplementation needs to be approached from the functional and metabolic point of view to identify factors that have a favorable impact, as well as the distinction between carcinoma and the type of supplementation to be implemented.

          Global cancer surgery: delivering safe, affordable, and timely cancer surgery.

          Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

            Effects of Nutritional Prehabilitation, With and Without Exercise, on Outcomes of Patients Who Undergo Colorectal Surgery: A Systematic Review and Meta-analysis

            Although there have been meta-analyses of the effects of exercise-only prehabilitation on patients undergoing colorectal surgery, little is known about the effects of nutrition-only (oral nutritional supplements with and without counseling) and multimodal (oral nutritional supplements with and without counseling and with exercise) prehabilitation on clinical outcomes and patient function after surgery. We performed a systemic review and meta-analysis to determine the individual and combined effects of nutrition-only and multimodal prehabilitation compared with no prehabilitation (control) on outcomes of patients undergoing colorectal resection.

              Bioelectrical impedance analysis: population reference values for phase angle by age and sex.

              Phase angle is an indicator based on reactance and resistance obtained from bioelectrical impedance analysis (BIA). Although its biological meaning is still not clear, phase angle appears to have an important prognostic role. The aim of this study was to estimate population averages and SDs of phase angle that can be used as reference values. BIA and other methods used to evaluate body composition, including hydrodensitometry and total body water, were completed in 1967 healthy adults aged 18-94 y. Phase angle was calculated directly from body resistance and reactance, and fat mass (FM) was estimated from the combination of weight, hydrodensitometry, and total body water by using the 3-compartment Siri equation. Phase angle values were compared across categories of sex, age, body mass index (BMI), and percentage FM. Phase angle was significantly (P < 0.001) smaller in women than in men and was lower with greater age (P < 0.001). Phase angle increased with an increase in BMI and was significantly inversely associated with percentage fat in men. Phase angle was significantly predicted from sex, age, BMI, and percentage FM in multiple regression models. Phase angle differs across categories of sex, age, BMI, and percentage fat. These reference values can serve as a basis for phase angle evaluations in the clinical setting.
