Evolution of nutritional status and survival in patients with cancer on tyrosine kinase inhibitors treatment. / Evolución nutricional y de la supervivencia en un grupo de pacientes oncológicos en tratamiento con inhibidores de tirosina quinasa.

BACKGROUND AND OBJECTIVE: Treatment with oral antineoplastic agents known as tyrosine kinase inhibitors (TKIs) is new and, thus, little is known about their impact on nutritional status (NS), dietary intake, quality of life, and survival. The aim of this study was to provide information on these components in order to guide future nutritional recommendations. PATIENTS AND METHOD: A prospective, observational study in adults who start treatment with TKIs, in whom NS was assessed using the Patient-Generated Subjective Global Assessment (PG-SGA), anthropometric measures, biochemical parameters, and dietary intake (24-hour dietary recall). The EORTC QLQ-C30 was used to assess quality of life. Nonparametric tests were used in statistical analysis, and survival was analyzed using Kaplan-Meier and log-rank curves. RESULTS: Of the overall sample, 21.7% had moderate malnutrition according to PG-SGA, and 74.2% moderate weight loss at 6 months, but no patient had BMI<18.5kg/m2. Patients with moderate malnutrition had lower survival at four years of diagnosis (log-rank=0.015). Energy intake was lower than recommended by the ESPEN 2017 congress, and no patient covered the protein requirements (1.5g protein/kg weight) during follow-up. A worse score on the global health scale of the EORTC QLQ-C30 was related to worse NS. CONCLUSIONS: Treatment with TKIs does not appear to have a significant impact on NS and quality of life after 6 months of follow-up. Malnutrition should be prevented through individualized nutritional advice because it is related to shorter survival.

Clinical and economic impact of the taurolidine lock on home parenteral nutrition.

INTRODUCTION: catheter-related bloodstream infections (CRBSI) are one of the most serious concerns in patients on home parenteral nutrition (HPN) which involve high morbidity and cost for the healthcare system. In the last years, taurolidine lock has proven to be beneficial in the prevention of CRBSI; however, the evidence of its efficiency is limited. OBJECTIVE: to determine if taurolidine lock is a cost-effective intervention in patients on HPN. MATERIALS AND METHODS: retrospective study in patients on HPN with taurolidine lock. We compared the CRBSI rate and cost of its complications before and during taurolidine lock. RESULTS: thirteen patients, six (46%) males and seven (54%) females, with a mean age of 61.08 (SD = 14.18) years received taurolidine lock. The total days of catheterization pre and per-taurolidine were 12,186 and 5,293, respectively. The underlying disease was benign in five patients (38.5%) and malignant in eight (61.5%). The CRBSI rate pre vs per-taurolidine was 3.12 vs 0.76 episodes per 1,000 catheter days (p = 0.0058). When the indication was a high CRBSI rate, this was 9.72 vs 0.39 (p < 0.001) in pre and per-taurolidine period respectively. No differences have been observed in the occlusion rates. None of the patients reported any adverse effects. The total cost of CRBSI in the pre-taurolidine period was 151,264.14 euros vs 24,331.19 euros in the per-taurolidine period. CONCLUSIONS: our study shows that taurolidine lock is a cost-effective intervention in patients on HPN with high risk of CRBSI.

Impact of kitchen organization on oral intake of malnourished inpatients: A two-center study / Impacto de la organización de la cocina hospitalaria en la ingesta del paciente malnutrido: estudio de dos centros

Aim: To determine the impact of the type of hospital kitchen on the dietary intake of patients. Methods: A cross-sectional, two-centre study, of cooking in a traditional kitchen (TK) and in a chilled kitchen (CK). Subjective global assessment (SGA) was used for nutritional diagnosis. Before study start, a dietician performed a nutritional assessment of the menus of each hospital. All dishes were weighed upon arrival to the ward and at the end of the meal. Results: 201 and 41 patients from the centres with TK and CK respectively were evaluated. Prevalence of malnutrition risk was 50.2% at the hospital with TK and 48.8% at the hospital with CK (p=0.328). Forty-eight and 56 dishes were nutritionally evaluated at the hospitals with TK and CK respectively. Intake analysis consisted of 1993 and 846 evaluations in the hospitals with TK and CK respectively. Median food consumption was 76.83% at the hospital with TK (IQR 45.76%) and 83.43% (IQR 40.49%) at the hospital with CK (p<0.001). Based on the prevalence of malnutrition, a higher protein and energy intake was seen in malnourished patients from the CK as compared to the TK hospital, but differences were not significant after adjustment for other factors. Conclusions: Cooking in a chilled kitchen, as compared to a traditional kitchen, may increase energy and protein intake in hospitalized patients, which is particularly beneficial for malnourished patients (AU)

Objetivo: Determinar el impacto de la organización de la cocina hospitalaria en la ingesta dietética del paciente hospitalizado. Metodología: Estudio transversal, realizado en dos centros hospitalarios, uno con cocina tradicional (CT) y otro con cocina en línea fría (CLF). La valoración subjetiva global fue empleada para el diagnóstico nutricional. Una dietista-nutricionista realizó una calibración nutricional de los platos y los menús de cada hospital antes de empezar el estudio. La técnica de valoración de la ingesta fue la pesada de alimentos antes y después de la ingesta, siempre en presencia del paciente. Resultados: Fueron reclutados 201 pacientes del centro con CT y 41 del CLF. La prevalencia de riesgo de desnutrición fue del 50,2% en el CT y de 48,8% en el CLF (p=0,328). En el CT fueron valorados nutricionalmente 48 platos y 56 del CLF. Respecto al análisis de la ingesta, se realizaron 1.993 registros en el centro CT y 846 en el centro CLF. La mediana de ingesta en el CT fue de 76,83% (RIC 45,76%) y 83,43% (RIC 40,49%) en el CLF (p<0,001). Teniendo en cuenta la prevalencia de malnutrición, se observó una mayor ingesta proteica y energética en pacientes malnutridos en el CLF en comparación con el CT, aunque estas diferencias no fueron significativas tras ajustarlas a diferentes factores de confusión. Conclusiones: Cocinar en una cocina en línea fría podría mejorar la ingesta calórica y proteica del paciente hospitalizado, especialmente en pacientes malnutridos (AU)

Ingesta dietética de pacientes adultos con esofagitis eosinofílica que siguen una dieta de exclusión de seis grupos de alimentos / Dietary intake for adult eosinophilic esophagitis patients following a six-food-groups elimination diet

Introducción: la esofagitis eosinofílica (EEo) es una enfermedad inmunoalérgica crónica emergente en adultos. Surge como respuesta disfuncional frente a los antígenos de los alimentos y se caracteriza por síntomas recurrentes de disfunción esofágica e inflamación. El tratamiento farmacológico y dietético se basa en su patogénesis y debe ser individualizado. Uno de los posibles abordajes dietéticos se basa en la eliminación empírica de alimentos que con mayor frecuencia causan EEo. Objetivo: evaluar la ingesta dietética de los pacientes con EEo que siguen la dieta de exclusión de los seis grupos de alimentos (DESGA) y conocer sus posibles carencias nutricionales. Métodos: estudio transversal descriptivo en un grupo de pacientes con EEo que inició tratamiento con DESGA durante el periodo de marzo del 2013 hasta marzo del 2015. Se evaluó la ingesta mediante registro de 72 h. Se compararon los resultados con las referencias para población adulta sana española Moreiras, 2013. Para el análisis estadístico se usaron los test de Mann-Whitney, Krhuskall-Wallis y chi cuadrado. Signifi cación p < 0,05. Resultados: se incluyeron en el estudio 14 pacientes. En algunos de ellos, la ingesta dietética siguiendo DESGA fue deficitaria en energía, proteínas y fibra. Tampoco consiguieron cubrir las ingestas de micronutrientes de calcio, zinc, magnesio, ácido fólico, niacina y vitaminas B2 y D, teniendo en cuenta edad y sexo, el 60% de la muestra. Conclusiones: el abordaje terapéutico mediante DESGA, teniendo en cuenta las características de la dieta, debe acompañarse de una evaluación periódica del estado nutricional, que incluya micronutrientes y una pauta de suplementación específica (AU)

Introduction: Eosinophilic esophagitis (EoE) is an emerging chronic immune/antigen mediated inflammatory disease in adults. It develops as a dysfunctional response to food antigens and is characterized by recurrent symptoms of esophageal dysfunction and inflammation. Drug and dietary treatment are based on its pathogenesis and should be individualized. One of the possible dietary approaches is based on empirical elimination of foods which most commonly cause EoE. Objective: To evaluate dietary intake of patients who follow the diet consisting of the exclusion of six food groups (DESGA) and to know its potential nutritional deficiencies. Methods: Cross-sectional study of patients who started treatment with DESGA diet between March 2013 and March 2015. A 72 h dietary record was completed. The results were compared with the references for the Spanish healthy adult population Moreiras, 2013. Statistical analysis included Mann-Whitney, Kruskal-Wallis and Chi-square tests. Significance was set at p < 0.05. Results: The study included 14 patients. For some of them, the DESGA diet was defi cient inenergy, protein and fiber. Taking into account age and sex, sixty percent of the sample did not get adequate amount of calcium, zinc, magnesium, folic acid, niacin, vitamin B2 and vitamin D. Conclusions: Considering the characteristics of the DESGA diet, this therapeutic approach must be accompanied by a periodic assessment of nutritional status, including micronutrients and a pattern of specific supplementation (AU)

Ingesta dietética y estado nutricional de pacientes oncológicos que inician tratamiento con inhibidores tirosina quinasa / Dietary intake and nutritional status in oncology patients who start treatment with tyrosine kinase inhibitors

Introducción: la investigación sobre nuevos antineoplásicos orales sigue avanzando en los últimos años mientras que su repercusión sobre la ingesta dietética y el estado nutricional (EN) no progresa de la misma forma. Objetivos: evaluar la ingesta dietética y EN de pacientes que inician tratamiento con inhibidores tirosina quinasa (ITK) y valorar el impacto que tienen sobre ellos. Métodos: estudio observacional y prospectivo de seis meses en el que se incluyeron pacientes que iniciaban tratamiento con ITK. La ingesta se evaluó con: recuerdo 24 h y cuestionario de frecuencia de consumo. El EN se valoró con: medidas antropométricas y cuestionario de valoración subjetiva global generada por el paciente (VSGGP); los resultados se compararon con las referencias SENC-semFYC, 2007 y Moreiras O., 2013. Para el análisis estadístico se utilizaron: Test de Friedman, χ2, Wilcoxon, Kruskall-Wallis y Mann-Whitney. Significación p< 0,05. Resultados: se incluyeron 22 pacientes (54,5% hombres). Al inicio del tratamiento, el 73,9% tenía un EN adecuado según VSG-GP. No se produjeron pérdidas de peso significativas, pese a que un porcentaje elevado no cubrió los requerimientos energéticos y proteicos. El número de comidas se relacionó positivamente con la ingesta calórica. La ingesta y los patrones de frecuencia de consumo por grupos de alimentos tampoco variaron durante el tratamiento. Conclusión: la ingesta dietética al inicio del tratamiento no alcanza los requerimientos nutricionales. Los ITK no parecen afectar la ingesta ni el estado nutricional de los pacientes. El estudio de estos parámetros antes de comenzar el tratamiento evitaría futuras complicaciones y guiaría el consejo dietético (AU)

Background: in recent years, researching about new oral antineoplastics has progressed while its impact on dietary intake and nutritional status (NS) hasn’t developed enough yet. Objectives: dietary intake and NS assessment in patients who start treatment with tyrosine kinase inhibitors (TKI) and evaluate its impact on them. Methods: an observational, prospective-six-months study, in which were included patients starting treatment with TKI. The intake was evaluated by a 24 h dietary record and a food frequency questionnaire. The NS was evaluated by anthropometric measurements and the patient-generated Global Subjective Assessment (PG-GSA); the results were compared with the Spanish references (SENC-semFYC, 2007 and O. Moreiras, 2013). Friedman test, χ2, Wilcoxon, Kruskal-Wallis and Mann-Whitney were used in the statistical analysis. Significance p< 0.05. Results: 22 patients (54.5% male) were included. At baseline, NS was adequate in 73.9% of patients according PG-GSA. Weight loss was no significant, although a high percentage of the energy and protein requirements hadn´t been reached. The caloric intake was positively related with the number of meals. Dietary habits did not change during treatment. Conclusion: dietary intake did not reach nutritional requirements at baseline. The TKI don´t seem to affect the patient´s intake and nutritional status. The research about these parameters before starting treatment could prevent future complications and it would guide the dietary advice (AU)

Implantación de un sistema de gestión de calidad en una unidad de nutrición según la norma UNE-EN-ISO 9001: 2008 / Implementation of a quality management system in a nutrition unit according to ISO 9001: 2008

Introducción: la implantación de sistemas de gestión de calidad (SGC) en el sector sanitario ha presentado un gran avance en los últimos años, siendo una herramienta clave para la gestión y la mejora de los servicios ofrecidos a los pacientes. Objetivo: describir el proceso de implantación de un SGC según la Norma ISO 9001:2008 en una unidad de nutrición. Material y métodos: el proceso comenzó en octubre de 2012. Se contó con la asesoría del servicio de medicina preventiva y gestión de calidad (MPGC) del hospital. Al inicio se realizaron sesiones formativas sobre SGC y normas ISO para el personal. Se instauró un comité de calidad (CC) con representación del personal facultativo y de enfermería. Semanalmente, se reunían los miembros del CC y del servicio de MPGC para definir los procesos, los procedimientos y los indicadores de calidad. Antes de validarlos se probaron durante dos meses. Resultados: se identificaron y documentaron un total de 4 procesos (Valoración del estado nutricional, Indicación de tratamiento nutricional, Seguimiento del tratamiento nutricional y Planificación y control de la alimentación oral) y 13 procedimientos operativos donde quedó recogida toda la actividad de la unidad. Las interacciones entre ellos quedaron definidas en el mapa de procesos. En cada uno de los procesos se identificaron indicadores de calidad para medir el estado del SGC y detectar oportunidades de mejora. Se desarrollaron todos los documentos asociados a requerimientos de la Norma ISO 9001:2008: política de calidad, objetivos de calidad, manual de calidad, procedimiento de control de la documentación y registros, de auditoría interna, de no conformidad y de acciones correctivas y preventivas. La unidad obtuvo la certificación de AENOR en abril de 2013. Conclusiones: la implantación de un SGC supone hacer una reflexión sobre las actividades que realiza la unidad con el objetivo de satisfacer las expectativas de los usuarios que demandan nuestros servicios. Documentar dichas actividades asegura un mejor entendimiento de la organización, define las responsabilidades de todo el personal y provoca una mejor gestión del tiempo y los recursos. También mejora la comunicación interna y supone un elemento motivador. Explorar la satisfacción y expectativas de los pacientes permite incluir su punto de vista en el diseño de los procesos asistenciales (AU)

Introduction: the implementation of quality management systems (QMS) in the health sector has made great progress in recent years, remains a key tool for the management and improvement of services provides to patients. Aim: to describe the process of implementing a quality management system (QMS) according to the standard ISO 9001:2008 in a Nutrition Unit. Methods: the implementation began in October 2012. Nutrition Unit was supported by Hospital Preventive Medicine and Quality Management Service (PMQM). Initially training sessions on QMS and ISO standards for staff were held. Quality Committee (QC) was established with representation of the medical and nursing staff. Every week, meeting took place among members of the QC and PMQM to define processes, procedures and quality indicators. We carry on a 2 months follow-up of these documents after their validation. Results: a total of 4 processes were identified and documented (Nutritional status assessment, Nutritional treatment, Monitoring of nutritional treatment and Planning and control of oral feeding) and 13 operating procedures in which all the activity of the Unit were described. The interactions among them were defined in the processes map. Each process has associated specific quality indicators for measuring the state of the QMS, and identifying opportunities for improvement. All the documents associated with requirements of ISO 9001:2008 were developed: quality policy, quality objectives, quality manual, documents and records control, internal audit, nonconformities and corrective and preventive actions. The unit was certified by AENOR in April 2013. Conclusion: the implementation of a QMS causes a reorganization of the activities of the Unit in order to meet customer’s expectations. Documenting these activities ensures a better understanding of the organization, defines the responsibilities of all staff and brings a better management of time and resources. QMS also improves the internal communication and is a motivational element. Explore the satisfaction and expectations of patients can include their view in the design of care processes (AU)

Prevalence of diabetes, prediabetes, and stress hyperglycemia: insulin therapy and metabolic control in patients on total parenteral nutrition (prospective multicenter study).

OBJECTIVE: The prevalence of carbohydrate metabolism disorders in patients who receive total parenteral nutrition (TPN) is not well known. These disorders can affect the treatment, metabolic control, and prognosis of affected patients. The aims of this study were to determine the prevalence in noncritically ill patients on TPN of diabetes, prediabetes, and stress hyperglycemia; the factors affecting hyperglycemia during TPN; and the insulin therapy provided and the metabolic control achieved. METHODS: We undertook a prospective multicenter study involving 19 Spanish hospitals. Noncritically ill patients who were prescribed TPN were included, and data were collected on demographic, clinical, and laboratory variables (glycated hemoglobin, C-reactive protein [CRP], capillary blood glucose) as well as insulin treatment. RESULTS: The study included 605 patients. Before initiation of TPN, the prevalence of known diabetes was 17.4%, unknown diabetes 4.3%, stress hyperglycemia 7.1%, and prediabetes 27.8%. During TPN therapy, 50.9% of patients had at least one capillary blood glucose of >180 mg/dL. Predisposing factors were age, levels of CRP and glycated hemoglobin, the presence of diabetes, infectious complications, the number of grams of carbohydrates infused, and the administration of glucose-elevating drugs. Most (71.6%) patients were treated with insulin. The mean capillary blood glucose levels during TPN were: known diabetes (178.6 ± 46.5 mg/dL), unknown diabetes (173.9 ± 51.9), prediabetes (136.0 ± 25.4), stress hyperglycemia (146.0 ± 29.3), and normal (123.2 ± 19.9) (P<.001). CONCLUSION: The prevalence of carbohydrate metabolism disorders is very high in noncritically ill patients on TPN. These disorders affect insulin treatment and the degree of metabolic control achieved.

[Nutritional assessment and quality of life of oncology outpatients initiating treatment with tyrosine­kinase inhibitors]. / Seguimiento del estado nutricional y calidad de vida de pacientes que inician tratamiento con inhibidores tirosin kinasa.

BACKGROUND AND OBJECTIVE: The consumption of oral antineoplastics -and more particularly of tyrosine-kinase inhibitors (TKI)- has increased in recent years. These therapies show a better tolerance but still, the nutritional alterations related to their daily and chronic clinical use are under investigation. This study assesses the effects of TKI on the intake, nutritional status and micronutrients as well as the patients quality of life. METHODS: A prospective longitudinal study was conducted including adult patients having started some TKI treatment from July 2012 to June 2013, and a 6 month follow-up period was established. Demographic pharmacotherapeutic, nutritional and biochemical variables were collected and also a EORTC-QLQ30 questionnaire at baseline, first, third and sixth month of treatment. RESULTS: 31 patients were included in the study. The percentage of weight loss at treatment baseline was statistically matched to the results on the patient-generated Global Subjective Assessment. Appetite decreased after one month of treatment, and so did the calorie consumption; 62.1% of the patients lost weight, 55.5% on the third month and 70.6% on the sixth month. 6-17% of the patients suffered from malnutrition to some degree during the follow-up period and a decrease of calcium, phosphate and magnesium plasma levels was detected. The emotional scale was the one with a lowest score in EORTC QLQ-30, and fatigue and lack of appetite were the most common symptoms at treatment baseline, progressively increasing those of nausea, vomits and diarrhea. DISCUSSION: Patients treated with TKI did not show a relevant malnutrition. Considering the results, it is important to take into account weight loss at treatment baseline; it is also important to control calcium and phosphate levels during treatment, to advise and counsel the patient on the GI effects (nausea, vomits and diarrhea) and emotionally reinforce the patient.

Introducción y objetivo: El consumo de antineoplásicos orales y concretamente de inhibidores tirosin kinasa (ITK) se ha incrementado en los últimos años. Son terapias mejor toleradas y, sin embargo, las alteraciones nutricionales relativas a su uso clínico diario y crónico están aún en estudio. El presente estudio valora la repercusión de los ITK sobre la ingesta, estado nutricional y micronutrientes y valora la calidad de vida de estos pacientes. Métodos: Se realizó un estudio prospectivo y longitudinal en el que se incluyeron aquellos pacientes adultos que iniciaron tratamiento con algún ITK de julio 2012 a junio 2013 con un periodo de seguimiento de 6 meses. Se recogieron variables demográficas, farmacoterapéuticas, nutricionales, bioquímicas y el cuestionario EORTC-QLQ30 al inicio, primer, tercer y sexto mes de tratamiento. Resultados: Se incluyeron 31 pacientes. El porcentaje de pérdida de peso al inicio del tratamiento se relacionó estadísticamente con la clasificación de la Valoración Subjetiva Global-generada por el paciente. Tras un mes de tratamiento descendió el apetito, las calorías consumidas y un 62,1% de los pacientes perdió peso, 55,5% al tercer mes y 70,6% al sexto mes. Entre un 6-17% de los pacientes sufría algún grado de desnutrición durante el seguimiento y se detectó una disminución de los niveles plasmáticos de calcio, fosfato y magnesio. En el EORTC QLQ-30, la escala emocional fue la peor puntuada y los síntomas más comunes al inicio de tratamiento fueron la fatiga y pérdida de apetito, aumentando progresivamente las náuseas, vómitos y la diarrea. Discusión: Los pacientes tratados con ITK no presentaron una desnutrición importante. A la vista de los resultados es importante valorar la pérdida de peso al inicio de tratamiento, monitorizar los niveles de calcio y el fosfato durante el tratamiento, aconsejar y prevenir al paciente sobre los efectos gastrointestinales (náuseas, vómitos y diarrea) y reforzar emocionalmente al paciente.

N-3 fatty acids, cancer and cachexia: a systematic review of the literature.

Use of n-3 fatty acids (FA) has been reported to be beneficial for cancer patients. We performed a systematic review of the literature in order to issue recommendations on the clinical use of n-3 FA in the cancer setting. A systematic search was performed in MEDLINE, EMBASE, Cochrane and Healthstar databases. We selected clinical trials or prospective observational studies including patients with cancer and life expectancy >2 months, in which enteral supplements with n-3 FA were administered. Parameters evaluated individually were clinical (nutritional status, tolerance, survival and hospital stays), biochemical (inflammatory mediators), and functional (functional status, appetite and quality of life (QoL)). Seventeen studies met the inclusion criteria; eight were of high quality. The panel of experts established the following evidence: (1) oral supplements with n-3 FA benefit patients with advanced cancer and weight loss, and are indicated in tumours of the upper digestive tract and pancreas; (2) the advantages observed were: increased weight and appetite, improved QoL, and reduced post-surgical morbidity; (3) there is no defined pattern for combining different n-3 FA, and it is recommended to administer > 1.5 g/day; and (4) better tolerance is obtained administering low-fat formulas for a period of at least 8 weeks. All the evidences were grade B but for 'length of treatment' and 'advantage of survival' it was grade C. Our findings suggest that administration of n-3 FA (EPA and DHA) in doses of at least 1.5 g/day for a prolonged period of time to patients with advanced cancer is associated with an improvement in clinical, biological and QoL parameters.
