Nutritional management and clinical outcome of critically ill patients with COVID-19: A retrospective study in a tertiary hospital.

BACKGROUND & AIMS: Severe COVID-19 infection is characterized by an inflammatory response and lung injury that can evolve into an acute respiratory distress syndrome that needs support treatment in intensive care unit. Nutritional treatment is an important component of the management of critically ill patients and should be started in the first 48 h of ICU admission to avoid malnutrition. This study describes the characteristics of the patients treated in a tertiary hospital in Madrid during the months of March-May 2020 (first wave), the medical nutrition treatment employed and its influence in the clinical outcome of these patients. METHODS: This is a retrospective study including COVID-19 patients admitted in ICU that needed medical nutrition treatment (MNT). Collected variables included sex, age, BMI, underlying diseases, time from hospitalisation to ICU admission, type of respiratory support (invasive mechanical ventilation (IMV) or high flow nasal cannula (HFNC) or non-invasive ventilation (non-IMV)), caloric and protein requirements (25 kcal/kg adjusted body weight (ABW), 1.3 g/kg ABW/day), MNT type (enteral nutrition (EN), parenteral nutrition (PN), mixed EN + PN), total calories (including propofol) and proteins administered, percentage of caloric and protein goal in ICU day 4th and 7th, metabolic complications, acute kidney failure (AKF), length of stay (LOS) and mortality. Data are expressed as mean ± SD, median (IQR) or frequencies. Statistical analysis was performed with the IBM SPSS Statistics for Windows, Version 25.0. p < 0.05 were considered statistically significant. RESULTS: A total of 176 patients were included (72.7% male), 60.1 ± 13.5 years, BMI 29.9 ± 5.4 kg/m2. Underlying diseases included 47.4% overweight, 39.8% obesity, 49.1% hypertension, 41.4% dyslipidaemia. 88.6% of patients needed IMV, 89.1% prone position, 2.9% ECMO. Time to ICU admission: 2 (4.75) days. Estimated caloric and protein requirements were 1775 ± 202 kcal and 92.4 ± 10.3 g. Calories and proteins administered at days 4th and 7th were 1425 ± 577 kcal and 66 ± 26 g and 1574 ± 555 and 74 ± 37, respectively. Most of the patients received PN (alone or complementary to EN) to cover nutritional requirements (82.4% at day 4th and 77.9% at day 7th). IVM patients received more calories and proteins during the first week of ICU admission. Complications included 77.8% hyperglycaemia, 13.2% hypoglycaemia, 83.8% hypertriglyceridemia, and 35.1% AKF. ICU LOS was 20.5 (26) days. The mortality rate was 36.4%. CONCLUSIONS: In our series, the majority of patients reached energy and protein requirements in the first week of ICU admission due to the use of PN (total or complementary to EN). Patients with HFNC or non-IMV may be at risk of malnutrition if total or complementary PN to oral diet/ONS/tube feeding is not used to cover nutritional requirements. Therefore, if EN is not possible or insufficient, PN can be safely used in critically ill patients with COVID-19 with a close monitoring of metabolic complications.

The economic costs of home parenteral nutrition: Systematic review of partial and full economic evaluations.

BACKGROUND & AIMS: Home parenteral nutrition (HPN) is indicated in patients with chronic intestinal failure. The aim of the current study was to review existing scientific literature of full or partial economic evaluations associated to HPN. METHODS: A bibliographic database search was undertaken in PubMed (MEDLINE), Embase and Scopus, complemented by a reference list search. We combined search terms regarding HPN and costs/health economics. The inclusion criteria included: a) population: all population and age groups; b) intervention: partial or full HPN; c) comparator: no parenteral nutrition, continued or intermittent hospital based PN, other nutritional interventions or no comparator; d) outcomes: cost outcomes and economic evaluations associated to HPN. A different quality assessment tool was used for each of the different type of economic approach. RESULTS: Twenty-three papers were included in the final review. 21 were partial economic evaluations (16 cost-of-illness studies and 5 cost analyses), and 2 were full economic evaluations, both cost-utility analysis. Most studies investigated costs from a healthcare perspective (n = 18), therefore they included only direct costs. Three studies included personal costs for HPN patient. None of the studies included productivity costs. CONCLUSIONS: Most scientific literature regarding the economic costs of HPN comes from partial economic evaluations, such as cost-of-illness studies and cost analysis. According to them, HPN is an expensive treatment, although cost saving when compared to hospital based parenteral nutrition (PN). Full economic evaluations proved HPN as being cost-effective than hospital based PN, however more research is needed to confirm this in all settings.

Direct costs of a home parenteral nutrition programme.

BACKGROUND & AIMS: Home parenteral nutrition (HPN) is a lifesaving treatment for people with chronic intestinal failure and its cost has been reported to be very high. The purpose of the present paper was to study the direct healthcare and non-healthcare costs associated with the HPN programme managed by a tertiary hospital. METHODS: Observational, retrospective study of all adult patients on HPN from 11.1.2014 to 10.31.2015 treated at Gregorio Marañón University Hospital (Madrid, Spain). An economic evaluation was undertaken to calculate the direct healthcare (HPN provision, outpatient monitoring and management of complications) and non-healthcare costs (transportation process) of the HPN programme. The variables were collected from medical records, the dispensary and the hospital's financial services. The unit costs were taken from official price lists. RESULTS: Thirty-two patients met the inclusion criteria. Total direct healthcare and non-healthcare costs amounted to €13,363.53 per patient (€124.02 per patient per day). The direct healthcare costs accounted for 98.32% of overall costs, while the non-healthcare costs accounted for the remaining 1.68%. HPN provision accounted for the majority of the costs (74.25%), followed by management of complications (21.85%) and outpatient monitoring (2.23%). CONCLUSIONS: The direct healthcare costs accounted for the majority of HPN expenditure, specifically HPN provision was the category with the highest percentage.

Driving the Crystallization of Zeolites.

The synthesis of zeolites with new structures and/or improved properties heavily relies on trial and error efforts that are not entirely blind, as the large empirical background accumulated for the last 7 decades can be, to some extent, rationalized and purposefully used to make new materials. The so-called structure-directing factors may be combined to promote (or frustrate) the crystallization of a particular structure. This personal account opens with the concept of geoinspiration, as suggested by Prof. Ruiz-Hitzky, and its application to zeolite synthesis. We then provide a concise overview of structure-direction in the synthesis of zeolites and detail examples, both new and from the literature, on how they can be combined to drive the crystallization towards (or away from) structures displaying particular features.

Effect of inulin and fructo-oligosaccharide on the prevention of acute radiation enteritis in patients with gynecological cancer and impact on quality-of-life: a randomized, double-blind, placebo-controlled trial.

BACKGROUND/OBJECTIVES: The pathogenesis of enteritis after abdominal radiotherapy (RT) is unknown, although changes in fecal microbiota may be involved. Prebiotics stimulate the proliferation of Lactobacillus spp and Bifidobacterium spp, and this may have positive effects on the intestinal mucosa during abdominal RT. SUBJECTS/METHODS: We performed a randomized, double-blind, placebo-controlled trial involving patients with gynecological cancer who received abdominal RT after surgery. Patients were randomized to receive prebiotics or placebo. The prebiotic group received a mixture of fiber (50 inulin and 50% fructo-oligosaccharide), and the placebo group received 6 g of maltodextrin twice daily from 1 week before to 3 weeks after RT. The number of bowel movements and stool consistency was recorded daily. Diarrhea was evaluated according to the Common Toxicity Criteria of the National Cancer Institute. Stool consistency was assessed using the 7-point Bristol scale. Patients' quality-of-life was evaluated at baseline and at completion of RT using the EORTC-QLQ-C30 (European Organization for Research and Treatment of Cancer quality-of-life Questionnaire C30) test. RESULTS: Thirty-eight women with a mean age of 60.3±11.8 years participated in the study. Both groups (prebiotic (n=20) and placebo (n=18)) were comparable in their baseline characteristics. The number of bowel movements per month increased in both groups during RT. The number of bowel movements per day increased in both groups. The number of days with watery stool (Bristol score 7) was lower in the prebiotic group (3.3±4.4 to 2.2±1.6) than in the placebo group (P=0.08). With respect to quality-of-life, the symptoms with the highest score in the placebo group were insomnia at baseline and diarrhea toward the end of the treatment. In the prebiotic group, insomnia was the symptom with the highest score at both assessments, although the differences were not statistically significant. CONCLUSIONS: Prebiotics can improve the consistency of stools in gynecologic cancer patients on RT. This finding could have important implications in the quality-of-life of these patients during treatment.

[Nutritional support in chronic neurological diseases]. / Manejo nutricional en las enfermedades neurológicas crónicas.

Malnutrition is common in neurodegenerative disorders and is associated with a worse prognosis and an increased risk of complications. Factors leading to malnutrition in these patients are: diseased nutrient intake, due to anorexia, dysphagia and other factors, gastrointestinal symptoms, and energy expenditure alterations. Nutritional evaluation and monitoring is mandatory and should be part of regular clinical evaluation. It will help to identify those patients that need specialized nutritional support. In this paper, relevant aspects regarding nutritional evaluation and support in patients suffering from a neurodegenerative disorder are reviewed, including amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease and dementia.

Manejo nutricional en las enfermedades neurológicas crónicas / Nutritional support in chronic neurological diseases

La desnutrición es frecuente en las enfermedades neurodegenerativas y condiciona un peor pronóstico y un aumento del riesgo de complicaciones. Las causas más frecuentes son la disminución de la ingesta, debido a anorexia, disfagia y otros factores, los síntomas digestivos y las alteraciones del gasto energético. La valoración y monitorización nutricional debe formar parte de la evaluación clínica de estos pacientes y permitirá identificar a los pacientes que puedan precisar un soporte nutricional específico. En este artículo se revisan los aspectos más importantes de la evaluación y el tratamiento nutricional de las enfermedades neurodegenerativas más prevalentes: esclerosis lateral amiotrófica, la esclerosis múltiple, la enfermedad de Parkinson y las demencias (AU)

Nutrición en el paciente con ictus / Nutrition for stroke patients

La desnutrición es frecuente en los pacientes con ictus y se asocia con un aumento de la morbimortalidad y un mayor riesgo de discapacidad. La disminución de la ingesta es uno de los factores etiológicos más importantes de desnutrición en estos pacientes. La disfagia es especialmente frecuente y origina una alteración de la eficacia y la seguridad de la deglución, que da lugar a un mayor riesgo de desnutrición y deshidratación, aspiración, insuficiencia respiratoria y neumonía. La valoración del paciente con ictus requiere una evaluación del riesgo nutricional y de la presencia de disfagia. El soporte nutricional incluye la utilización de dieta oral adaptada, suplementos nutricionales orales o nutrición enteral, modalidad de elección en los pacientes con disfagia grave. En este trabajo se revisan los aspectos más relevantes sobre el riesgo nutricional de los pacientes con ictus, las pautas diagnósticas y las opciones terapéuticas, tanto en la fase aguda como en la rehabilitación (AU)

Malnutrition in common in patients with acute stroke and is associated with higher mortality, poor outcome and disability. Decreased intake is one of the most important factors leading to malnutrition in stroke patients. Dysphagia is especially common and is responsible of a decrease in safety and efficacy of swallowing that gives rise to an increased risk of malnutrition, dehydration, aspiration, pneumonia and respiratory failure. Clinical evaluation of stroke patients includes a nutritional risk and swallowing capacity assessment. Nutritional support may be necessary, with adapted oral diet, oral supplements. Enteral nutrition is needed in patients with severe dyaphagia. This article reviews the most relevant aspects regarding nutritional risk factors in stroke patients, evaluation and diagnosis and nutritional support, both in acute phase and during rehabilitation (AU)

Effect of a mixture of inulin and fructo-oligosaccharide on lactobacillus and bifidobacterium intestinal microbiota of patients receiving radiotherapy; a randomised, double-blind, placebo-controlled trial / Efecto de una mezcla de inulina y fructo-oligosacárido sobre la microflora intestinal de lactobacillus y bifidobacterium de pacientes que reciben radioterapia; un ensayo aleatorio, a doble ciego y controlado con placebo

Background & aims: The pathogenesis of enteritis after abdominal radiotherapy is unknown, although changes in faecal microbiota may be involved. In several studies, Lactobacillus and Bifidobacterium have proven beneficial for the host. Prebiotics stimulate the proliferation of Lactobacillus and Bifidobacterium, and this may have positive effects on the intestinal mucosa during abdominal radiotherapy. Methods: We performed a randomised double-blind, placebo-controlled trial including 31 patients with gynaecological cancer who received radiotherapy (29 sessions, 52.2 Gy) after surgery. Patients were randomised to two groups: prebiotic and placebo. The first group received a mixture of fibre (50% inulin and 50% fructo-oligosaccharide) and the second received 6 g of maltodextrin twice daily from one week before to three weeks after radiotherapy. Lactobacillus and Bifidobacterium counts were determined in faeces samples (day -7 before radiotherapy, day 15 of radiotherapy, at the end of treatment, and three weeks after radiotherapy) by culture in selective media and fluorescent in situ hybridization (FISH) using genus-specific probes. Bacterial counts by FISH were significantly higher than by culture method. Results: There were no differences in baseline microbiota between groups. At the end of radiotherapy, we observed a statistically significant decrease in Lactobacillus and Bifidobacterium counts in both groups. By cultural analysis, we observed higher numbers of Lactobacillus and Bifidobacterium three weeks after radiotherapy in the prebiotic group (5.6 vs. 6.3, p = 0.04 and 5.5 vs. 6 log cfu/g, p = 0.03). Conclusions: Abdominal radiotherapy negatively affects Lactobacillus and Bifidobacterium counts. The prebiotic mixture of inulin and fructoligosaccharide can improve the recovery of both genera after radiotherapy (AU)

Antecedentes y objetivos: Se desconoce la patogenia de la enteritis tras la radioterapia abdominal, si bien podrían estar implicados cambios en la microflora fecal. Diversos estudios han demostrado que los Lactobacillus y Bifidobacterium confieren beneficios al huésped. Los prebióticos estimulan la proliferación de Lactobacillus y Bifidobacterium y esto podría tener efectos positivos sobre la mucosa intestinal durante la radioterapia abdominal. Métodos: Realizamos un estudio de distribución aleatoria, a doble ciego y controlado con placebo que incluyó a 31 pacientes con cáncer ginecológico que recibieron radioterapia (29 sesiones, 52,2 Gy) tras la cirugía. Se distribuyó al azar a las pacientes en dos grupos: prebiótico y placebo. El primer grupo recibió una mezcla de fibra (50% de inulina y 50% de fructo-oligosacárido) y el segundo 6 g de maltodextrina dos veces al día desde una semana antes hasta 3 semanas después de la radioterapia. Se determinaron los recuentos de Lactobacillus y Bifidobacterium en muestras fecales (día 7 antes de la radioterapia, día 15 de radioterapia, al final del tratamiento y tres semanas después de la radioterapia) mediante un cultivo en medios seleccionados y con hibridación in situ fluorescente (FISH) con sondas específicas de la especie. Los recuentos bacterianos con FISH fueron significativamente superiores que por el método de cultivo. Resultados: No hubo diferencias en la microflora basal entre los grupos. Al final de la radioterapia, observamos un descenso estadísticamente significativo en los recuentos de Lactobacillus y Bifidobacterium en ambos grupos. Mediante el análisis de los cultivos, observamos un mayor recuento de Lactobacillus y Bifidobacterium a las tres semanas de finalizar la radioterapia en el grupo con prebiótico (5,6 frente a 6,3, p = 0,04 and 5,5 frente a 6 log ufc/g, p = 0,03). Conclusiones: La radioterapia abdominal afecta de forma negativa los recuentos de Lactobacillus y Bifidobacterium. La mezcla de prebióticos de inulina y fructo-oligo-sacárido puede mejorar la recuperación de ambas especies tras la radioterapia (AU)

[Persistent chylothorax in patient with lymphangioleiomyomatosis]. / Quilotórax persistente en paciente con linfangioleiomiomatosis.

Lymphangioleiomyomatosis (LAM) is a rare disease that affects women in fertile age and presents a systemic progressive evolution, being the lung and the mediastinic lymph nodes the most affected organs. The pulmonary disease is characterized by dyspnea, pleural effusion, hemoptysis and spontaneous pneumothorax, being the chylothorax a frequent complication in the course of this disease, appearing in up to 30% of cases. The treatment of chylothorax is not standardized and it is necessary a multidisciplinary approach: nutritional, pharmacological, respiratory and even surgery. These patients present high risk of malnutrition due to the constant loss of chyle, therefore a suitable nutritional management is essential to avoid more complications.

La linfangioleiomiomatosis (LAM) es una enfermedad poco frecuente que afecta a mujeres en edad fértil y presenta una evolución sistémica progresiva, siendo el pulmón y los ganglios mediastínicos los órganos más afectados. La afectación pulmonar se caracteriza por disnea, derrame pleural, hemoptisis y neumotórax espontáneo, siendo el quilotórax una complicación frecuente en el curso evolutivo de esta enfermedad, produciéndose hasta en el 30% de casos. El tratamiento del quilotórax no está estandarizado y precisa de un manejo multidisciplinar nutricional, farmacológico, respiratorio y en ocasiones quirúrgico. Estos pacientes presentan un alto riesgo de malnutrición debido a la pérdida continua de quilo, por lo que es fundamental un adecuado tratamiento (AU)

Cobertura de vacunación antigripal en niños de Montevideo en el año 2010 / Influenza vaccination coverage in children of Montevideo in 2010

En el año 2006 se realizó una encuesta en Montevideo en niños entre 6 y 23 meses que mostró una muy baja cobertura de vacunación antigripal. El objetivo del presente estudio fue evaluar la cobertura de la misma vacuna durante el año 2010, en niños de Montevideo entre 6 y 23 meses y entre 2 y 5 años. Material y métodos: estudio observacional, descriptivo en población perteneciente a ASSE (sector público) y dos mutualistas de Montevideo (sector privado). Los datos se obtuvieron a través de encuesta realizada a padres y tutores, con formulario anónimo. Se interrogó sobre las razones para vacunar y las razones para no hacerlo. Resultados: se encuestaron responsables de 650 niños, 50.5% del grupo de 6 a 23 meses y 49.5% del grupo de 2 a 5 años. Se vacunaron 453 niños (69.7%), 69% del sector privado y 70.4% del sector público. La principal razón para vacunarse fue la indicación médica y la principal para no hacerlo fue la ausencia de indicación. Discusión: es difícil lograr altas coberturas de vacunación antigripal tanto en nuestro país como en otros. En el grupo en que es posible comparar, se obtuvieron en el año 2010 mejores resultados que en el 2006. Es probable que el temor a la pandemia haya sido factor determinante. Pero siempre la indicación médica tiene un rol preponderante en lograr mejores resultados.

Atrophy of the intestinal villi in a post-gastrectomy patient with severe iron deficiency anemia.

BACKGROUND & AIMS: Iron deficiency anemia is a common complication of gastric surgery that in certain patients can be refractory to treatment with oral iron and needs to be treated parenterally. METHODS: A 48-year woman underwent gastric surgery for a gastric ulcer. She was referred to the nutrition unit for the study and treatment of a 3-year iron deficiency anemia refractory to oral iron supplementation. Blood tests, endoscopy and jejunal biopsy were made to study the case. RESULTS: Intestinal villi atrophy in the absence of celiac disease was the result. She was treated with intravenous iron, resolving the villous atrophy and thus oral iron supplementation could be effective. CONCLUSION: This case illustrates that iron deficiency may cause villous atrophy. In this setting, parenteral iron administration is necessary to correct the haematological and non-hematological alterations associated with this deficiency.

Introducción y objetivos: La anemia ferropénica es una complicación frecuente tras la cirugía gástrica que en algunos pacientes puede ser refractaria al tratamiento con hierro oral, siendo necesaria su administración por vía parenteral. Métodos: Presentamos el caso de una mujer de 48 años intervenida de gastrectomía para tratamiento de una úlcera gástrica. Fue remitida a la unidad de nutrición para estudio y tratamiento de una anemia ferropénica de 3 años de evolución refractaria al tratamiento con hierro oral. Para el estudio del caso se realizó analítica y endoscopia digestiva alta con biopsia yeyunal. Resultados: En el estudio realizado la paciente presentaba atrofia de la mucosa yeyunal en ausencia de enfermedad celíaca. Fue tratada con hierro intravenoso desapareciendo la atrofia intestinal, tras lo cual continuamos con suplementos de hierro por vía oral. Conclusión: Este caso ilustra que la deficiencia de hierro puede producir atrofia intestinal. Si esto ocurre, es necesario la suplementación de este metal por vía parenteral para corregir las alteraciones hematológicas y no hematológicas asociadas a esta deficiencia (AU)

Long-term prevalence of oropharyngeal dysphagia in head and neck cancer patients: Impact on quality of life.

BACKGROUND & AIMS: To determine the prevalence of dysphagia in head and neck cancer patients treated with surgery and radiotherapy or chemoradiotherapy. To study the impact of dysphagia on food habits, nutritional status, and quality of life. METHODS: Retrospective cross-sectional study of 87 head and neck cancer patients treated with surgery and radiotherapy or chemoradiotherapy from January 2000 through May 2005. Time since surgery was 28.5+/-17.8 months. A clinical test was used to detect dysphagia. A nutritional assessment was performed in all patients. A questionnaire was used to evaluate quality of life. RESULTS: Oropharyngeal dysphagia was present in 50.6% of patients, mostly to solid foods (72.4%). Patients with total glossectomy and chemoradiotherapy had the highest rate of dysphagia. Nutritional support was necessary in 57.1% of patients. Malnutrition was present in 20.3% of patients, mainly marasmus (81%). Fifty-one percent of patients reported a decrease in their quality of life due to dysphagia. CONCLUSIONS: We found a high prevalence of dysphagia in head and neck cancer patients treated with surgery and coadjuvant treatment. This problem negatively affects their quality of life. It is important that nutritional surveillance be provided to detect it and to prevent malnutrition.

[Gastric surgery as a nutritional risk factor]. / Cirugía gástrica como factor de riesgo nutricional.

BACKGROUND: The stomach has a role in the digestion and absorption of nutrients, so patients are in nutritional risk after gastric resection. The aim of this work was to study the nutritional status of postgastrectomy outpatients followed in our hospital. METHODS: We retrospectively studied 54 patients (27 M, 27 F) followed more than 12 months postgastrectomy. Mean age was 61 +/- 14 yr and median follow-up was 35 months. The nutritional assessment included anthropometry, biochemical data and measurement of bone mineral density by dual-energy X-ray absorptiometry. The statistical analysis was performed by non-parametric tests. RESULTS: Malignancy was the most frequent indication (85%), 63% of patients had total gastrectomy. Patients were supplemented with iron (43%), B12 (87%), calcium (18%) and vitamin D (17%). 13% of patients had a BMI < 18.5. The incidence of 25 OH vitamin D deficiency and secondary hyperparathyroidism was 45% and 76%, respectively. The incidence of osteoporosis at lumbar spine was 46%. Matched with same age-sex people patients had 85.6% of bone mineral density. CONCLUSIONS: The loss of weight and the metabolic bone disease were the most prevalent impairments after gastric resection. These impairments point to the importance of a nutritional surveillance of patients after gastric resection.

Cirugía gástrica como factor de riesgo nutricional / Gastric surgery as a nutritional risk factor

Objetivo: El estómago tiene un papel importante en la digestión y absorción de nutrientes, por lo que los pacientes con resección gástrica están en riesgo nutricional. El objetivo del estudio fue evaluar el estado nutricional de pacientes gastrectomizados seguidos en una consulta externa de Nutrición de un Hospital General Universitario. Material y métodos: Estudiamos de manera retrospectiva 54 pacientes (27 V, 27 M) con un tiempo mínimo de evolución desde la gastrectomía de 12 meses. La edad media fue 61 ± 14 años y la media de seguimiento 35 meses. La valoración nutricional incluyó antropometría, datos bioquímicos y valoración de la densidad mineral ósea mediante DEXA. El estudio estadístico se realizó con pruebas no paramétricas. Resultados: La indicación principal de la cirugía fue oncológica (85%). El 63% de los pacientes presentaban gastrectomía total. Los pacientes recibieron suplementos de hierro (43%), vitamina B12 (87%), calcio (18%) y vitamina D (17%). El 13% de los pacientes tenían bajo peso (IMC < 18,5). La incidencia de deficiencia de 25 OH vitamina D y de hiperparatiroidismo secundario fue de 45% y 76%, respectivamente. La incidencia de osteoporosis en columna fue del 46%. Comparadas con personas de su misma edad y sexo, los pacientes mantenían el 85,6% de la densidad mineral ósea. Conclusiones: La pérdida de peso y la enfermedad metabólica ósea fueron las complicaciones más prevalentes en nuestros pacientes gastrectomizados. Por ello, creemos que es importante realizar un seguimiento nutricional en los pacientes gastrectomizados
