Effect of a personalized nutritional intervention program on nutritional status, quality of life and mortality in hemodialysis patients / Efecto de un programa de intervención nutricional personalizado en el estado nutricional, calidad de vida y mortalidad en pacientes en hemodiálisis

Objective: dietary advice provided through a nutritional intervention program (NIP) is recommended by renal clinic guidelines to prevent or treat malnutrition, that could improve quality of life (QoL) and survival in hemodialysis (HD) patients. This study set out to evaluate the effect of a personalized NIP on the nutritional status and its impact on QoL and mortality in dialyzed patients. Material and methods: this was a 12-month intervention study with regular follow-up in which nutritional parameters were measured at baseline and after 6 and 12 months. QoL was assessed by the Kidney Disease Quality of Life version 1.2 (KDQOL-SF) at baseline and at the end of the study. All dialyzed patients received individualized consultations with a trained dietitian. The content of the nutritional education program included a personalized meal plan and educational materials addressing nutrition to manage fluids, electrolytes, and vitamin D. Results: a total of 75 patients were included. After the NIP, visceral proteins, phosphorous, potassium and vitamin D levels had improved significantly (p < 0.001). The percentage of well-nourished patients increased by 30 % (p < 0.001). At the end of the study, the well-nourished patients had significantly improved scores on the general summary areas of the KDQOL-SF, reduced worry concerning fluid and dietary restrictions (p < 0.001), and the survival rate was 12 months longer (p < 0.01). Conclusion: the results of this study suggest that personalized NIP contributed to improved nutritional status, QoL and survival in HD patients. (AU)

Expert design thinking workshops to analyze users' perceived applicability of NUTRI-ONCOCARE algorithm to prevent and treat malnutrition in cancer patients under routine clinical practice conditions in Spain: the ALLIANCE study.

PURPOSE: NUTRI-ONCOCARE algorithm has been developed to identify and treat patients with solid tumors who are at risk of malnutrition. The present study is aimed at analyzing users' opinion about this new tool and at assessing whether it is perceived as useful to achieve the behavioral change required for a successful integration of nutritional assessment into routine cancer care. METHODS: Design thinking Double Diamond process was applied. A multidisciplinary team composed of ten potential end-users (four oncologists, three endocrinologists, one nutritionist, and two hospital pharmacists) participated in three different workshops aiming to analyze the different tasks included within the NUTRI-ONCOCARE algorithm. RESULTS: Users agreed on the need to perform nutritional assessment around cancer diagnosis and through the course of the disease using standardized tools included in hospital nutritional protocols and involving healthcare professionals with nutrition expertise. Nutritional evaluation and intervention should be individual and comprehensive, considering not only nutritional parameters but also patients' functional status. According to participants' opinion, the implementation of nutritional screening in routine clinical practice is limited by the lack of time and staff to conduct nutritional assessments, the low level of nutrition expert participation, and the poor support provided by hospital managers, which are often unaware of nutrition's impact in cancer care. CONCLUSIONS: Experts recognized the importance of considering nutritional status in cancer patients and identified the opportunity provided by the NUTRI-ONCOCARE algorithm for this purpose, as it meets main requirements for being used routinely in clinical practice.

Hypovitaminosis D and its relationship with nutritional status and quality of life in patients undergoing haemodialysis / Hipovitaminosis D y su relación con el estado nutricional y la calidad de vida en pacientes incluidos en un programa de hemodiálisis

Objective: to assess the prevalence of hypovitaminosis D in patients undergoing haemodialysis (HD) and to determine its relationship with nutritional status and quality of life (QoL). Material and methods: 120 patients were included in the study. The Malnutrition-Inflammation Score (MIS) was used to detect nutritional risk. QoL was evaluated by Kidney Disease Quality of Life version 1.2 (KDQOL-SF). Patients were stratified into three groups according to their vitamin D status: sufficiency (≥ 30 ng/dl), insufficiency (29-10 ng/dl) and deficiency (< 10 ng/dl). Results: hypovitaminosis D was detected in 71 % of the patients studied. Multiple linear regression analysis showed that vitamin-D deficiency was the most significant predictor of low KDQOL-SF scores. It explained 21 % of the variance in the Kidney Disease Component Summary, 27 % of that in the Physical Component Summary, and 22 % of that in the Mental Component Summary. Multiple logistic regression analysis showed that only vitamin-D deficiency was significantly associated with malnutrition (OR, 14.6, p < 0.001). Conclusion: HD patients frequently present with hypovitaminosis D. There is a significant correlation between vitamin-D deficiency, poorer nutritional status, and worse QoL in dialysed patients.

Material y métodos: un total de 120 pacientes fueron incluidos. La escala de Malnutrición-Inflamación (MIS) se utilizó para la detección del riesgo nutricional. La CV fue evaluada por el cuestionario Kidney Disease Quality of Life versión 1.2 (KDQOL-SF). Los pacientes fueron estratificados en tres grupos de acuerdo con el estado de la vitamina D: suficiencia (≥ 30 ng/dl), insuficiencia (29-10 ng/dl) y deficiencia (< 10 ng/dl). Resultados: se observó hipovitaminosis D en el 71 % de los pacientes. El análisis de regresión lineal múltiple mostró que la deficiencia devitamina D fue el predictor más significativo de peores resultados en el cuestionario KDQOL-SF. La deficiencia de 25(OH)D explicó el 21 % de la varianza en el componente sumatorio de la enfermedad renal, el 27 % en el componente sumatorio físico y el 22 % en el componente sumatorio mental. Cuando evaluamos el estado nutricional, el análisis de regresión logística multivariante mostró que solo la deficiencia de vitamina D presenta un efecto significativo en la desnutrición (OR: 14.6, p < 0,001). Conclusión: de nuestros hallazgos concluimos que la hipovitaminosis D es muy frecuente entre los pacientes en HD y que su deficiencia está asociada un deterioro del estado nutricional y peor percepción de la calidad de vida.

Assessment of the importance of ostomy patients' understanding of dietary and lifestyle recommendations.

Introduction: Objective: the objective of our study was to evaluate the level of understanding of ostomy patients regarding lifestyle, diet, and high output stoma (HOS) management recommendations provided by healthcare professionals. Method: a prospective study to follow up ostomy patients at nutritional consultations was designed. The follow-up process was performed 7-10 days after hospital discharge and again one month later. At the first visit, patients were instructed in the detection and management of HOS. At the second visit, the level of understanding of the training received was assessed using an evaluation questionnaire. A descriptive analysis of the answers to each of the questionnaire's items was performed. Fisher's exact test was used to evaluate differences in the level of understanding recorded with the questionnaire. Results: a total of 35 patients were recruited; 71.4 % did not provide correct answers to all the questions. There were no significant differences in the correctness of the answers to the questionnaire according to education level. Conclusions: many patients do not adequately understand the information provided by healthcare professionals and this could have a negative impact on the incidence of clinical complications.

Introducción: Objetivo: el objetivo de nuestro estudio fue evaluar el nivel de comprensión de los pacientes ostomizados con respecto a las recomendaciones sobre estilo de vida, dieta y manejo de la ostomía de alto débito (OAD) proporcionadas por los profesionales de la salud. Método: se diseñó un estudio prospectivo para el seguimiento de pacientes ostomizados en consulta de nutrición. El seguimiento se realizó 7-10 días después del alta hospitalaria y a continuación un mes después. En la primera visita, se instruyó a los pacientes sobre la detección y el tratamiento de OAD. En la segunda visita se evaluó el nivel de comprensión de la formación recibida mediante un cuestionario de evaluación. Se registraron las respuestas dadas a cada uno de los ítems del cuestionario y se realizó un análisis descriptivo. Para evaluar las diferencias en el nivel de comprensión registrado con el cuestionario se utilizó la prueba exacta de Fisher. Resultados: se reclutaron 35 pacientes. El 71,4 % no respondieron correctamente a todas las preguntas. La exactitud de las respuestas al cuestionario no mostró diferencias significativas según el nivel educativo. Conclusiones: un gran número de pacientes no comprende adecuadamente la información que ofrecen los profesionales sanitarios y esto podría tener un impacto negativo en el desarrollo de complicaciones clínicas.

The impact of nutritional status on health-related quality of life in hemodialysis patients.

Malnutrition is frequent in hemodialysis (HD) patients. Nutritional deficiencies may negatively impact quality of life (QOL). This study examines the utility of the Malnutrition-Inflammation Score (MIS) in detecting nutritional risk (NR) and assesses the correlation between nutritional status and QOL in dialysis patients upon starting a nutritional intervention program (NIP). One hundred and twenty patients were included in this cross-sectional study. The MIS was used to detect NR and the Kidney Disease Quality of Life (KDQOL-SF) instrument version 1.2 was used to assess QOL. 62% of patients were found to be at NR (MIS > 5). Nutritional status was significantly correlated with all generic QOL sub-scales. On a multiple linear regression analysis, malnutrition showed the highest level of explanation in the Kidney Disease Summary Component which explained 28.9% of the variance; the Physical Component Summary which explained 33% of the variance; and the Mental Component Summary which explained 21.5% of the variance. Malnutrition was found to be the most significant predictor of impaired scores on the KDQOL-SF. The use of MIS to identify patients at NR and a nutritional assessment to detect malnutrition in its early stages are important given the effects a NIP can have on improving QOL in HD patients.

Impact of a nutrition consultation on the rate of high output stoma-related readmission: an ambispective cohort study.

The aims of this study were to assess the impact of a follow-up nutrition consultation for ostomy patients on the rate of high output stoma (HOS)-related readmissions, as well as on the detection of poor nutritional status and their management, and to determine the associated economic impact. A single-centre ambispective cohort study was conducted in which all adult patients undergoing intestinal resection and stoma creation were recruited. Two nutrition consultations were established for early follow-up after hospital discharge and patients were prospectively included. Additionally, a retrospective search was carried out to include a control group. In both groups, a 12-month follow-up was conducted to record readmissions associated with high output stoma. A multivariate logistic regression was performed. Statistical significance level was established at p < 0.05. 170 patients were recruited, 85 patients in each cohort. Demographic data and clinical characteristics were recorded. A significant difference was observed in HOS-related readmissions, with readmission rates of 28.6% vs 10.3% in the retrospective and prospective cohort, respectively. At the first follow-up consultation, 50.5% of patients presented some degree of protein-calorie malnutrition. A statistically significant improvement in nutritional status was observed in the second evaluation. The intervention carried out resulted in a total saving of €24,175. Early follow-up of patients after discharge resulted in a significant reduction in the rate of HOS-related readmissions and allowed to identify a high percentage of patients with malnutrition. The cost analysis showed the process to be a cost-effective improvement.

Impact of weight loss on cancer patients' quality of life at the beginning of the chemotherapy.

PURPOSE: Among the prognostic factors relevant to the condition of oncological patients, nutritional status (NS) has the greatest single impact on quality of life (QL). The goals of our study were to evaluate the influence of NS, weight loss (WL), and the presence of cachexia, prior to the initiation of chemotherapy, on the patient's QL. METHODS: Adult patients (aged ≥ 18 years) diagnosed with solid tumours for whom chemotherapy was started between April 2016 and June 2017 were eligible for inclusion in the study. They were asked to complete a QL questionnaire (Functional Assessment of Cancer Treatment (FACT-G)) at the beginning. The presence or absence of cachexia was evaluated at the outset, following the definition proposed by Fearon and nutritional assessment by the Patient-Generated Subjective Global Assessment (PG-SGA) scale. RESULTS: A total of 177 patients completed the FACT-G, the 60% receiving curative therapy. At the start of the treatment, 58.2% of patients had experienced WL, with an average of 4.4 ± 7.4%, and 19% were at risk of malnutrition. Patient who presented cachexia at diagnosis, were treated with palliative intention, had a Nutriscore ≥ 5 points or presented malnutrition in accordance with PG-SGA had a poorer QL (p < 0.05). Greater WL was associated with a worsened QL (p = 0.001). Breast cancer patients presented an inverse correlation between the %WL and the initial score in the FACT-G (r = - 0.304, p = 0.023), whereas no such correlation was observed for the other types of tumour (r = - 0.012, p = 0.892). CONCLUSIONS: These results underline the relation of NS before starting chemotherapy and QL. Greater WL was associated with a worsened QL, especially in women with breast cancer.

Evaluation of a protocol to detect malnutrition and provide nutritional care for cancer patients undergoing chemotherapy.

Patients with cancer frequently experience malnutrition, which is associated with higher rates of morbidity and mortality. Therefore, the implementation of strategies for its early detection and for intervention should improve the evolution of these patients. Our study aim is to design and implement a protocol for outpatients starting chemotherapy, by means of which any malnutrition can be identified and treated at an early stage. Before starting chemotherapy for patients with cancer, a complete assessment was made of their nutritional status, using the Nutriscore screening tool. When nutritional risk was detected, an interventional protocol was applied. Of 234 patients included in the study group, 84 (36%) required an individualised nutritional approach: 27 (32.1%) presented high nutritional risk, 12 had a Nutriscore result ≥ 5 and 45 experienced weight loss during chemotherapy. Among this population, the mean weight loss (with respect to normal weight) on inclusion in the study was - 3.6% ± 8.2. By the end of the chemotherapy, the mean weight gain was 0% ± 7.3 (p < 0.001) and 71.0% of the patients had experienced weight gain or maintenance, with respect to the initial weight. More than a third of cancer patients who start chemotherapy are candidates for early nutritional intervention. This finding highlights the importance of early identification of patients at risk in order to improve the efficacy of nutritional interventions, regardless of the stage of the disease.

Nutritional risk and malnutrition rates at diagnosis of cancer in patients treated in outpatient settings: Early intervention protocol.

OBJECTIVES: Malnutrition is frequent in patients with cancer and is associated with a higher rate of morbidity and mortality. However, a significant number of patients at nutritional risk remain undetected due to the lack of a routine screening procedure during diagnosis. Costa del Sol Hospital in Marbella (Málaga), Spain has implemented a protocol for outpatients with cancer aimed at identifying and treating malnutrition at an early stage. The aim of this study was to determine the prevalence of nutritional risk and the rate of malnutrition when cancer is diagnosed. METHODS: We conducted a complete assessment of the nutritional status of patients with cancer of the upper digestive tract (esophagus, stomach, pancreas, or biliary tract) or head and neck cancer. Using the Nutriscore tool at the first oncology consultation, a screening for nutritional risk was performed for patients with other solid tumors. When nutritional risk was detected, a complete nutritional assessment was conducted. RESULTS: Of 295 consecutive patients, 21.4% were found to be at nutritional risk (Nutriscore ≥5). After complete assessment, a moderate degree of malnutrition was observed in 76% and severe malnutrition in 12%. Among patients with colorectal cancer or tumors of gynecologic origin, only 7.5% presented nutritional risk, but 52.8% presented cachexia. CONCLUSION: The high rate of malnutrition observed and the identification of cachexia at an early stage highlight the importance of obtaining early identification of patients at risk to improve the efficacy of nutritional interventions.

Systematic review of drug bioavailability following gastrointestinal surgery.

PURPOSE: Inter- and intraindividual pharmacokinetics variability in humans affects the way in which drugs act on the body. Gastrointestinal surgery has an impact on this variability and significantly alters the kinetics of drugs in post-surgical patients. The way in which pharmacokinetic profiles are modified depends on the type of operative procedure performed. The extent to which the absorption of different groups of drugs is affected varies according to the site and length of intestinal resections. METHODS: A literature search was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Three databases were searched: MEDLINE, Embase, and the Cochrane Library. For each drug, potential changes in absorption were described, including recommendations extracted from the results of the studies and collected according to authors' criteria as practical conclusions, and grades of recommendation were determined by levels of evidence using the Oxford Centre for Evidence-Based Medicine scale. RESULTS: Sixty-eight articles were collected during the selection process after the bibliographic search. The main outcomes for 60 drugs from the various studies were classified according to each type of surgery. CONCLUSIONS: Modifications in the digestive tract secondary to gastrointestinal surgery may compromise the bioavailability of drugs. Decreased absorption surface, gastric emptying speed, and gastric pH alteration are factors to be taken into account in the management of pharmacological treatment after surgery. Evidence supported by data in clinical practice is scarce, but after studying the pharmacokinetic profile of some molecules, it is possible to offer recommendations for its adaptation to the patient's clinical situation.

Effects of cyclic parenteral nutrition on parenteral-associated liver dysfunction parameters.

INTRODUCTION: One of the most common complications of parenteral nutrition (PN) is liver dysfunction (LD). Therapeutic approaches for LD include, among others, administering cyclic parenteral nutrition (cPN), allowing some hours for metabolic rest. The purpose of this study was to evaluate the effectiveness of cPN in treating PN-associated LD. MATERIALS AND METHODS: A retrospective observational study was carried out at the Costa del Sol Hospital in Spain between 2013 and 2014. The study involved inpatients ≥18 years old prescribed with cPN due to the development of PN-associated LD. The hepatic biochemical parameters measured at baseline and after completion of cPN included aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP) and total bilirubin (TB). Quantitative values (age, biochemical parameters) were compared using matched Student's t-test; the mean change in qualitative variables (sex, indication of PN, hepatic comorbidities, presence of insulin in cPN, infection during cPN, management of LD prior to cPN administrarion) was estimated using Mann-Whitney U test, and bivariate correlation between quantitative variables was determined by Spearman's coefficient of correlation. RESULTS: Thirty-seven patients met inclusion criteria. All hepatic function parameters except ALP improved after the administration of cPN, with statistically significant differences (p < 0.05) in AST GGT and TB. CONCLUSION: cPN improves PN-associated LD by restoring abnormal AST, GGT, and BT levels to normal, and reducing ALT levels close to normal. The results obtained suggest that the administration of cPN is effective in reverting PN-associated LD.

Protocol for the detection and nutritional management of high-output stomas.

INTRODUCTION: An issue of recent research interest is excessive stoma output and its relation to electrolyte abnormalities. Some studies have identified this as a precursor of dehydration and renal dysfunction. A prospective study was performed of the complications associated with high-output stomas, to identify their causes, consequences and management. MATERIALS AND METHODS: This study was carried out by a multidisciplinary team of surgeons, gastroenterologists, nutritionists and hospital pharmacists. High-output stoma (HOS) was defined as output ≥1500 ml for two consecutive days. The subjects included in the study population, 43 patients with a new permanent or temporary stoma, were classified according to the time of HOS onset as early HOS (<3 weeks after initial surgery) or late HOS (≥3 weeks after surgery). Circumstances permitting, a specific protocol for response to HOS was applied. Each patient was followed up until the fourth month after surgery. RESULTS: Early HOS was observed in 7 (16%) of the sample population of 43 hospital patients, and late HOS, in 6 of the 37 (16%) non-early HOS population. By type of stoma, nearly all HOS cases affected ileostomy, rather than colostomy, patients. The patients with early HOS remained in hospital for 18 days post surgery, significantly longer than those with no HOS (12 days). The protocol was applied to the majority of EHOS patients and achieved 100% effectiveness. 50% of readmissions were due to altered electrolyte balance. Hypomagnesaemia was observed in 33% of the late HOS patients. CONCLUSION: The protocol developed at our hospital for the detection and management of HOS effectively addresses possible long-term complications arising from poor nutritional status and chronic electrolyte alteration.

Ostomías de alto débito: detección y abordaje / High output stoma: detection and approach

La ostomía de alto débito es una complicación frecuente en pacientes portadores de ileostomías que está poco identificada y que no suele ser adecuadamente abordada desde el punto de vista clínico. No está descrita de manera consensuada, pudiendo variar entre débitos de 2.000 ml en 24h o alrededor de 1.500 ml en durante 3-5 días, según los autores. Suele presentar graves consecuencias para el paciente tanto a corto como a largo plazo y está asociada a reingresos. Se presenta una revisión de la literatura publicada al respecto sobre los factores relacionados con la resección quirúrgica que influyen en una posterior aparición de esta complicación, las causas que intervienen en su desarrollo, la necesidad de establecer un concepto objetivo y claro de alto débito así como las implicaciones negativas presenta. Así mismo se recoge como debe realizarse el manejo de estos pacientes con respecto al tratamiento y abordaje nutricional (AU)

High output stoma is a frequent complication in patients with ileostomies that is not well identified and is not often properly addressed by clinicians. It has not been described properly, and can vary between debits of 2.000ml in 24 h to 1.500 ml in 3-5 days, according to different authors. Frequently presents both short-term and long-term negative implications for patients and is associated with readmissions. We present a review of published literature focusing in surgical resection-related factors that influence a later appearance of this complication, causes involved in its development, the need to establish a clear and objective concept of high ouput as well as the negative implications it presents. Also we develop how should we the management of these patients regarding treatment and nutritional approach (AU)

[Hypersensibility reaction to parenteral nutrition approach; a case report]. / Abordaje de una posible reacción de hipersensibilidad a nutrición parenteral; a propósito de un caso.

Parenteral nutrition (PN) is essential in the treatment of many hospitalized patients. However, administration of PN is not without potential complications and patients are exposed to related possible adverse reactions such as hypersensitivity. For that reason and because of the complexity of this treatment, PNs are considered by the ISMP (Institute for Safe Medication Practice) a high risk medication. Following is introduced the case of an oncologic patient with severe malnutrition, who after receiving PN for several days, developed a hypersensitivity reaction that could have being associated with intravenous mixture administration. Our aim is to analize the difficulties related with pre-surgery nutrition and to clarify the main possible causes of the reaction.

La nutrición parenteral (NP) constituye un elemento esencial en el tratamiento de muchos pacientes hospitalizados. Sin embargo, su administración no está exenta de complicaciones quedando sujeta a la aparición de reacciones adversas de diversa índole como las de hipersensibilidad, por lo que es considerada por el ISMP (Institute for Safe Medication Practice) como medicación de riesgo. Se presenta el caso de una paciente oncológica con desnutrición severa, que tras recibir NPT durante varios días, desarrolla una reacción de hipersensibilidad que, ante la posibilidad de estar asociada a la administración de la mezcla intravenosa, nos planteo la dificultad de la nutrición preoperatoria y nos llevó a analizar las causas probables de esta reacción.

Since de Tarpon Springs Consensus Conference in 1987, the Bioenterics Intragastric Balloon represents the standard model for obesity treatment with this technique. Nevertheless, over the last 30 years, especially for the last ten years, novel concept of balloons has appeared, as well as new alternative models, which are reviewed in this paper.

Desde la Conferencia de Consenso de Tarpon Spring en 1987, el Balón Intragástrico de Bioenterics se ha impuesto como modelo en el tratamiento de la obesidad con esta técnica. No obstante, a lo largo de los 30 últimos años, y en especial en los 10 últimos, han aparecido nuevos conceptos de balón intragástrico así como modelos alternativos de balón que revisamos en este trabajo.
