A Program of Life-Style Modification Improved the Body Weight and Micronutrient Status in Obese Patients after Bariatric Surgery.

INTRODUCTION: Bariatric surgery is an efficient approach to rapidly reduce morbid obesity and associated comorbidities. However, approximately one-fourth of patients experience weight and comorbidity recurrence, and both obesity and bariatric surgery can lead to micronutrient deficiencies. Implementing a structured program of lifestyle modification (PLM) might enhance weight loss and improve micronutrient status. METHODOLOGY: A total of 121 severely obese patients underwent Roux-en-Y gastric bypass (RYGB). Among them, 71 adhered to a PLM involving dietary changes (low- and very-low-calorie Mediterranean diets) and physical exercises (aerobic and resistance training) both before and after surgery, while 50 patients followed a conventional protocol. Anthropometric measurements and serological parameter quantifications were conducted throughout the procedures. RESULTS: The obese study population, primarily female (76.9%), with an average age of 47.11 ± 9.68, and a body mass index (BMI) of 44.68 ± 5.08 kg/m2, underwent either RYGB with a PLM or a conventional procedure. Before surgery, the PLM group exhibited significant reductions in body weight (6.3%) and phosphoremia compared to the conventional protocol (0.78%). Post-RYGB, the PLM group demonstrated shortened in-hospital stays and further BMI reductions (-16.12 kg/m2) that persisted for up to 2 years. Furthermore, the PLM group experienced increased plasma vitamin D levels (14.79 ng/mL vs. 1.2 ng/mL) for up to 2 years, as well as elevated folic acid (1.52 vs. -0.29 ng/mL) and phosphorus (0.48 vs. 0.06 mg/dL) levels at 1 month and 1 year after intervention, respectively. Notably, these effects were independent of weight loss. CONCLUSIONS: Initiating a structured PLM from the early stages of patients' preparation for RYGB could enhance and extend the benefits of weight loss and positively impact micronutrient (vitamin D, phosphorus, and folic acid) status in obese patients.

Twenty-five years of home parenteral nutrition outsourcing: the experience at Hospital Universitario La Paz, Madrid.

INTRODUCTION: For the last 20 years, most adult patients following home parenteral nutrition (HPN) under the care of the Clinical Nutrition and Dietetics Dept. of the La Paz University Hospital (Unidad de Nutrición Clínica y Dietética del Hospital Universitario La Paz), Madrid, Spain, have received their nutrition formula via a catering system (Nutriservice) responsible for its preparation and home distribution. AIM: To assess the clinical characteristics, quality of life and degree of satisfaction with the care received, of patients undergoing HPN who received their nutrition formulae via the named catering service. MATERIALS AND METHODS: The characteristics of the patients who received HPN via this service between 1992 and 2013 were retrospectively collected. Those patients still undergoing treatment completed a quality of life questionnaire, plus a survey of their satisfaction with the catering system and the care provided by our department. RESULTS: Seventy eight patients were examined; 57.7% were men. The mean age of the patients was 53.1±14.3 years. The most common underlying disease was cancer, both in advanced stage (33.8% of all cases) and in stages in which active treatment was being provided (34%). The most common indication for HPN was intestinal obstruction (46%). The median duration of HPN treatment was 96 [1-5334] days. The most common complication was catheter infection (72%). For the analysis of the results, the patients were divided depending on disease type: those with advanced stage cancer, those with cancer under active treatment and with a better prognosis, and those with non-oncological disease. The patients undergoing active oncological treatment believed the quality of their lives to have been improved by the Nutriservice catering system, and rated the care received by our department positively. CONCLUSION: In our experience, patients with cancer are those who most commonly receive HPN, especially those with advanced disease. Given the seriousness of their conditions, and the complexity surrounding the use of HPN, catering systems appear to offer a means of improving their quality of life.

Introducción: La mayoría de los pacientes adultos con nutrición parenteral domiciliaria (NPD) que dependen de la Unidad de Nutrición Clínica y Dietética del Hospital Universitario La Paz, reciben desde hace más de 20 años la fórmula de nutrición a través de un sistema de catering que elabora y distribuye directamente al domicilio del paciente. Objetivo: Evaluar las características clínicas, calidad de vida y grado de satisfacción con la atención recibida de los pacientes con nutrición parenteral domiciliaria que recibieron las fórmulas de nutrición mediante el sistema de catering: Nutriservice. Material y métodos: Se recogen retrospectivamente las características de los pacientes que utilizaron fórmulas de nutrición parenteral en su domicilio a través de Nutriservice, desde el año 1992 hasta la actualidad. Los pacientes en tratamiento activo realizaron un cuestionario de calidad de vida y encuesta de satisfacción sobre el sistema de catering y la atención prestada por nuestra Unidad. Resultados: Se registraron 78 pacientes, el 57,7% eran hombres y la edad media 53,1±14,3 años. La patología de base más frecuente fue el cáncer, tanto en estadios avanzados (34%) como en tratamiento activo (34%). El motivo principal de indicación fue la obstrucción intestinal (46%).La duración del soporte nutricional tuvo una mediana de 96 días (1-5334). Las complicaciones más frecuentes fueron las infecciones relacionadas con el catéter (72%). Se analizaron los resultados, clasificando a los pacientes según la enfermedad de base: cáncer en estadio avanzado, cáncer en tratamiento activo y mejor pronóstico y patología no oncológica. Los pacientes en tratamiento activo consideraron afectada su calidad de vida y valoraron positivamente el servicio ofrecido por Nutriservice y la atención recibida de la Unidad de Nutrición. Conclusión: En nuestra experiencia, los pacientes oncológicos son los que con mayor frecuencia tienen nutrición parenteral domiciliaria, siendo muy frecuente su indicación en estadios avanzados de la enfermedad. A la gravedad de la patología de base se une la complejidad de la NPD. Los sistemas de catering podrían ser una alternativa eficaz para mejorar la calidad de vida en algunos de estos pacientes.
