Objective: To describe the results of the home enteral nutrition (HEN) registry of the NADYA-SENPE group in 2011 and 2012. Material and methods: We retrieved the data of the patients recorded from January 1st 2011 to December 31st 2012. Results: There were 3021 patients in the registry during the period from 29 hospitals, which gives 65.39 per million inhabitants. 97.95% were adults, 51.4% male. Mean age was 67.64 ± 19.1, median age was 72 years for adults and 7 months for children. Median duration with HEN was 351 days and for 97.5% was their first event with HEN. Most patients had HEN because of neurological disease (57.8%). Access route was nasogastric tube for 43.5% and gastrostomy for 33.5%. Most patients had limited activity level and, concerning autonomy, 54.8% needed total help. Nutritional formula was supplied from chemist's office to 73.8% of patients and disposables, when necessary, was supplied from hospitals to 53.8% of patients. HEN was finished for 1,031 patients (34.1%) during the period of study, 56.6% due to decease and 22.2% due to recovery of oral intake. Conclusions: Data from NADYA-SENPE registry must be explained cautiously because it is a non-compulsory registry. In spite of the change in the methodology of the registry in 2010, tendencies regarding HEN have been maintained, other than oral route.

Objetivos: Comunicar los datos del Registro del Grupo NADYA SENPE de Nutrición Parenteral Domiciliaria NPD en España del año 2010. Material y métodos: Estudio descriptivo de la base de datos del Registro de ámbito nacional de NPD del grupo NADYA-SENPE (1 de enero de 2010 al 31 de diciembre de 2010). Para el cálculo de prevalencias se utilizó los últimos datos publicados por el Instituto Nacional de Estadística. Resultados: Se registraron 148 pacientes procedentes de 23 hospitales, 86 mujeres (58,11%) y 9 niños (6,08%). La edad media de los 139 pacientes adultos fue de 53,06 ± 15,41 años. La duración media de la NPD fue de 316,97 días/paciente. El diagnóstico más frecuente en los niños (menores de 14 años) fue intestino corto traumático con 5 casos (55,55%) y en los adultos la neoplasia en tratamiento paliativo 29 (19,59%). El motivo de la indicación de la NPD fue el síndrome de intestino corto en 74 ocasiones (47%). La vía de acceso más frecuentemente registrada fue el catéter tunelizado en 36 (22,78%) casos seguido del reservorio en 13 (8,23%) y otras vías en 3 ocasiones (1,90%). Se registraron 23 infecciones relacionadas con el catéter (82,14%), lo que representa 0,49/1000 días de NP y todas ellas ocurrieron en los adultos. A lo largo del año finalizaron 24 episodios de NPD, la causa más frecuente fue el paso a la vía oral en 12 episodios (50%). Se registró que los pacientes tenían una actividad normal en 70 episodios de NPD (44,30%) con una total autonomía en 88 de episodios (55,69%). Se identificaron 39 (24,68%) posibles candidatos para trasplante intestinal. Conclusiones: El número de pacientes registrados es discretamente inferior al del año anterior, aunque el número de hospitales participantes es el mismo. La complicación más frecuente sigue siendo la infección relacionada con el catéter aunque ha disminuido su incidencia respecto a años anteriores, presentándose la tasa más baja desde la creación del registro. Las diferencias en la participación en el registro observadas por Comunidades Autónomas lleva a plantear el desarrollo de estrategias de implementación del registro. Se observa un aumento progresivo de la duración de los días de NPD a lo largo de los años que hace pensar en la cronicidad de algunos pacientes, pero nos obliga a estudiar la existencia de un posible factor de confusión, en el caso de que existiera un olvido de cierre de algún episodio por lo que se hace necesario actualizar el registro con sistemas de alertas periódicas que faciliten la revisión de los pacientes incluidos y optimice la validez del registro.Objectives: To report the Group Registry NADYASENPE data about home parenteral nutrition (HPN) in Spain in 2010. Material and methods: A descriptive study of the database of the national registry of HPN of NADYA-SENPE (December 10, 2009 to December 10, 2010). For the calculation of prevalence the latest data published by the Institute National Statistics Office (01/01/2009) was used. Results: There were registered 148 patients from 23 hospitals, 86 women (58.11%) and 9 children (6.08%). The average age of the 139 patients older than 14 years was 53.06 ± 15.41 years. The average duration of HPN was 316.97 days/patient. The most common diagnosis in those younger than 14 years was short bowel traumatic with 5 cases (55.55%) and in those older than 14 years, palliative care cancer with 29 cases (19.59%). The reason for the indication for HPN was short bowel syndrome in 74 cases (47%). The access via most frequently recorded was tunneled catheter in 36 cases (22.78%) followed by implanted port-catheters in 13 cases (8.23%) and other pathways in 3 cases (1.90%). There were 23 catheterrelated infections (82.14%) which represented 0.49 /1,000 days of PN, all of which occurred in cases older than 14 years. During the year 24 episodes of HPN ended, the most frequent cause was the transition to oral nutrition in 12 episodes (50%). It was reported that patients had a normal activity in 70 episodes of HPN (44.30%) with complete autonomy in 88 episodes (55.69%). Some patients 39 (24.68%) were potential candidates for intestinal transplantation. Conclusions: The number of registered patients is slightly lower than the previous year, although the number of participating hospitals is the same. The most frequent complication remains catheter-related infection but its incidence has decreased from previous years, presenting the lowest rate since the creation of the record. Differences in participation in the registry observed in the Autonomous Communities causes the development of implementation strategies. There is a gradual increase in day length of HPN over the years, which suggests the chronic treatments of some patients and obliges to study the existence of a possible confounding factor, in case there is an oversight of closing an episode. Therefore, it is necessary to update the registry with warning systems that facilitate periodic review of the patients and optimize the validity of registration.

Objetivo: Comunicar los datos del registro de Nutrición Parenteral Domiciliaria (NPD) del grupo de trabajo NADYA-SENPE de los años 2007, 2008 y 2009. Material y métodos: Recopilación de los datos del registro "on-line" introducidos por las Unidades responsables del seguimiento de la NPD desde el 1 de enero de 2007 al 31 de diciembre de 2009 dividido por años naturales. Resultados: Año 2007: Se registraron 133 pacientes con NPD (61 hombres y 72 mujeres), de 21 hospitales. La edad media de los 119 pacientes mayores de 13 años fue de 53,7 ± 14,9 años, y de 3,6 ± 3,6 años la de los 14 pacientes que no los superaban. La patología más frecuente fue la neoplasia (24%) seguida de las alteraciones de la motilidad intestinal y la enteritis posradiación (ambas 14%). En el 43% de los casos el motivo de indicación fue el síndrome de intestino corto, seguido de malabsorción (27%) y obstrucción intestinal (23%). Los catéteres más utilizados fueron los tunelizados (69%) y los reservorios subcutáneos (27%). Las complicaciones mas frecuentes fueron las sépticas relacionadas con el catéter con una tasa de 0,92 infecciones por cada mil días de NPD. La duración de la NPD fue superior a los dos años en el 50% de los casos. Al acabar el año seguía en activo el 71,4% de los pacientes; la muerte fue la principal causa de la finalización de la NPD (57,5%). El 26% de los pacientes se consideraron candidatos al trasplante intestinal. Año 2008: Se registraron 143 pacientes con NPD (62 hombres y 81mujeres), de 24 hospitales. La edad media de los 133 pacientes mayores de 13 años fue de 54,7 ± 13,9 años, y de 3,7 ± 0,6 años la de los 10 pacientes que no los superaban. La patología más frecuente fue la neoplasia (20%) seguida de la enteritis rádica (14%) y las alteraciones de la motilidad intestinal (13%). En el 44% de los casos el motivo de indicación fue el síndrome de intestino corto, seguido de malabsorción (28%) y obstrucción Nutriintestinal (20%). Los catéteres más utilizados fueron los tunelizados (60%) y los reservorios subcutáneos (29%). Las complicaciones mas frecuentes fueron las sépticas relacionadas con el catéter con una tasa de 0,50 infecciones por cada mil días de NPD. La duración de la NPD fue superior a los dos años en el 67% de los casos. Al acabar el año seguía en activo el 71,6% de los pacientes; la muerte fue la principal causa de la finalización de la NPD (52,4%). El 29% de los pacientes se consideraron candidatos al trasplante intestinal. Año 2009: Se registraron 158 pacientes con NPD (62 hombres y 96 mujeres), de 24 hospitales. La edad media de los 149 pacientes mayores de 13 años fue de 55,2 ± 13,0 años. La patología más frecuente fue la neoplasia (25%) seguida de la enteritis rádica (12%) y las alteraciones de la motilidad intestinal (11%). En el 42% de los casos el motivo de indicación fue el síndrome de intestino corto, seguido de malabsorción y obstrucción intestinal (ambas 23%). Los catéteres más utilizados fueron los tunelizados (60%) y los reservorios subcutáneos (36%). Las complicaciones mas frecuentes fueron las sépticas relacionadas con el catéter con una tasa de 0,67 infecciones por cada mil días de NPD. La duración de la NPD fue superior a los dos años en el 58% de los casos. Al acabar el año seguía en activo el 79,2% de los pacientes; el paso a alimentación oral fue la principal causa de la finalización de la NPD (48%). El 23% de los pacientes se consideraron candidatos a trasplante intestinal. Conclusiones: Se observa un aumento progresivo de los pacientes registrados respecto a años anteriores con una prevalencia muy variable según comunidades autónomas. La principal patología sigue siendo la neoplasia, que ocupa el primer lugar desde 2003. Se aprecia una disminución de las complicaciones sépticas relacionadas con el catéter en los dos últimos años, siendo la tasa de 2008 la más baja desde la creación del registro.Objective: To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the years 2007, 2008 and 2009. Methodology: We compiled the data from the on-line registry introduced by the responsible Units for the monitoring of HPN from January 1st 2007 to December 31st 2009. Included fields were: age, sex, diagnosis and reason for HPN, access path, complications, beginning and end dates, complementary oral or enteral nutrition, activity level, autonomy degree, product and fungible material supply, withdrawal reason and intestinal transplant indication. Results: 2007: 133 patients with HPN were registered (61 males and 72 females), belonging to 21 hospitals. Average age for the 119 patients older than 13 years old was 53.7 ± 14.9 years, and 3.6 ± 3.6 y. for the 14 patients under 14 years old. Most frequent pathology was neoplasm (24%), followed by intestinal motility disorders and actinic enteritis (14% both). The reason for HPN provision was short bowel syndrome (43%), malabsorption (27%), and intestinal obstruction (23%). Tunnelled catheters were mostly used (69%), followed by implanted port-catheters (27%). Catheter related infections were the most frequent complications, with a rate of 0.92 episodes/103 HPN days. HPN was provided for more than two years in 50% of the cases. By the end of 2007, 71.4% of the patients remained active; exitus was the most frequent reason to end HPN (57.5%). 26% of the patients were eligible for intestinal transplant. 2008: 143 patients with HPN were registered (62 males and 81 females), belonging to 24 hospitals. Average age for the 133 patients older than 13 years old was 54.7 ± 13.9 years, and 3.7 ± 0.6 y. for the 10 patients under 14 years old. Most frequent pathology was neoplasm (20%), followed by actinic enteritis (14%) and intestinal motility disorders (13% ). The reason for HPN provision was short bowel syndrome (44%), malabsorption (28%), and intestinal obstruction (20%). Tunnelled catheters were mostly used (60%), followed by implanted port-catheters (29%). Catheter related infections were the most frequent complications, with a rate of 0.50 episodes/10³ HPN days. HPN was provided for more than two years in 67% of the cases. By the end of 2008, 71.6% of the patients remained active; exitus was the most frequent reason to end HPN (52.4%). 29% of the patients were eligible for intestinal transplant. 2009: 158 patients with HPN were registered (62 males and 96 females), belonging to 24 hospitals. Average age for the 149 patients older than 13 years old was 55.2 ± 13.0 years. Most frequent pathology was neoplasm (25%), followed by actinic enteritis (12%) and intestinal motility disorders (11%). The reason for HPN provision was short bowel syndrome (42%), malabsorption, and intestinal obstruction (23% both). Tunnelled catheters were mostly used (60%), followed by implanted port-catheters (36%). Catheter related infections were the most frequent complications, with a rate of 0.67 episodes/10³ HPN days. HPN was provided for more than two years in 58% of the cases. By the end of 2009, 79.2% of the patients remained active; full oral nutrition was the most frequent reason to end HPN (48%). 23% of the patients were eligible for intestinal transplant. Conclusions: We observe an increase in registered patients with respect to previous years, with a very different prevalence among regions. Neoplasia remains as the main pathology since 2003. We observe a decrease in catheter-related infections in the last two years, being the 2008 rate the smallest since the register´s beginning.

Introducción: La cirugía bariátrica ha demostrado ser un tratamiento eficaz para la pérdida de peso en pacientes con obesidad severa, recomendándose la aplicación de un protocolo de actuación multidisciplinar. Objetivos: Evaluar la utilidad de la implantación de un protocolo de actuación en cirugía de la obesidad basado en el Documento de consenso español de la SEEDO. Métodos: Estudio restrospectivo comparativo de resultados de pacientes intervenidos previamente (51 pacientes) y tras la implantación del protocolo (66 pacientes). Se recogieron datos de: antropometría , comorbilidades pre y postcirugía, complicaciones nutricionales y quirúrgicas postcirugía, test de Calidad de Vida validado, y hábitos alimentarios. Resultados: Los abandonos (17,6%) y el alcoholismo (5,8%) fueron mayores en pacientes preprotocolo frente postprotocolo (4,5% y 3% respectivamente) con diferencias estadísticamente significativas. La mortalidad fue del 2% en los preprotocolo y del 0% en los postprotocolo. Los hábitos alimentarios fueron mejores en los postprotocolo, presentando mayor porcentaje de trastornos de conducta alimentaria los preprotocolo (5,1%) aunque sin significación estadística. La mejoría de la calidad de vida fue superior en los postprotocolo en todos los items, pero solo con significación estadística en la actividad sexual (p 0,004). El 70,5% de los pacientes preprotocolo tenían más de una complicación nutricional frente al 32,8% de los postprotocolo (p < 0,05). No hubo diferencias en cuanto a porcentaje de sobrepeso perdido a los dos años (superior al 50% en el 81,3% de los casos preprotocolo y en el 74,8% de los postprotocolo) ni evolución de comorbilidades. Conclusiones: La cirugía bariátrica consigue excelentes resultados en: pérdida de peso, comorbilidades y calidad de vida, pero presenta complicaciones nutricionales, quirúrgicas y psiquiátricas que exigen un abordaje multidisciplinar y protocolizado. Nuestro protocolo mejora resultados de tasa de abandonos, trastornos de conducta alimentaria, hábitos alimentarios, complicaciones nutricionales y mejoría de calidad de vida.Introduction: Bariatric surgery has been shown to be an effective therapy for weight loss in patients with severe obesity, and the implementation of a multidisciplinar management protocol is recommended. Objectives: To assess the usefulness of the implementation of a management protocol in obesity surgery based on the Spanish Consensus Document of the SEEDO. Methods: Retrospective comparative study of the outcomes in patients previously operated (51 patients) and after the implementation of the protocol (66 patients). The following data were gathered: anthropometry, pre-and post-surgery comorbidities, post-surgical nutritional and surgical complications, validated Quality of Life questionnaire, and dietary habits. Results: Withdrawals (l7.6%) and alcoholism (5.8%) were higher in patients pre- versus post-implementation of the protocol (4.5% vs. 3%, respectively), the differences being statistically significant. The mortality rate was 2% in the pre-protocol group and 0% in the postprotocol group. The dietary habits were better in the post-protocol group, the pre-protocol group presenting a higher percentage of feeding-behavior disorders (5.1%) although not reaching a statistical significance. The improvement in quality of life was higher in the post-protocol group for all items, but only reaching statistical significance in sexual activity (p = 0.004). In the pre-protocol group, 70.5% of the patients had more than one nutritional complication vs. 32.8% in the post-protocol group (p < 0.05). There were no differences regarding the percentage of weight in excess lost at two years (> 50% in 81.3% in the pre-protocol group vs. 74.8% in the pos-protocol group) or the comorbidities. Conclusions: Bariatric surgery achieves excellent outcomes in weight loss, comorbidities, and quality of life, but presents nutritional, surgical, and psychiatric complications that require a protocol-based and multidisciplinary approach. Our protocol improves the outcomes regarding the withdrawal rates, feeding-behavior disorders, dietary habits, nutritional complications, and quality of life.

Objetivo: Describir las características de la Nutrición Enteral Domiciliaria (NED) en España, registrada por el grupo NADYA-SENPE durante el año 2009. Material y métodos: Recopilación y análisis descriptivo de los datos del registro de NED del grupo NADYA-SENPE desde el 1 de enero al 31 de diciembre de 2009. Resultados: Se registraron 6.540 pacientes, 5,11% más que en el año anterior y 6.649 episodios de NED (3.135 en mujeres, 47,93%) pertenecientes a 32 centros hospitalarios. Siendo 6.238 (95,38%) mayores de 14 años. La edad media en los menores de 14 años fue de 3,67 ± 2,86 y de 72,10 ± 16,89 en los mayores de 14 años. La enfermedad de base que se registró con más frecuencia fue la neurológica en 2.732 (41,77%) ocasiones, seguida de la neoplasia en 1838; 28,10%. La vía de acceso se registró en 1.123 (17,17%) de los episodios, siendo más frecuente la administración por sonda nasogástrica 562 (50,04%). El tiempo medio de tratamiento nutricional fue de 323 días (10,77 meses). Finalizaron 606 episodios de NED, siendo el motivo más frecuentes el fallecimiento del enfermo, lo que aconteció en 295 (48,68%) ocasiones y el paso a alimentación oral en 219 (36,14%). Los pacientes mantenían una actividad normal en 2162 episodios de NED (32,55%) y en 2468 (37,13%) hacían vida "cama-sillón". El grado de dependencia fue "total" en 2598 (39,07%) de los episodios registrado. El suministro de la fórmula nutricional se realizó desde el hospital en 4.183 (62,91%) casos y por la farmacia de referencia en 2.262 (el 34,02%) y el material fungible se suministró desde el hospital en 3.531 (53,11%) de los casos. Conclusiones: El número de pacientes con NED registrados es superior al del año 2008, continuando con el incremento progresivo desde el inicio del registro. Las características de los mismos mantiene el mismo perfil que en años anteriores con pequeñas variaciones.Objective: To describe the Home Enteral Nutrition Characteristics (HEN) recorded by the group NADYA-SENPE during 2009. Material and method: collection and analysis of the data voluntary recorded in the HEN registry from the NADYA-SENPE group from January 1st to December 31st. Results: 6.540 HEN patients were registered, 5.11% more than the previous year and 6,649 episodes (3,135 in women, 47,93%) from 32 different hospitals. 6,238 of them (95,38%) were over 14 years. The mean age of the patients under 14 yr was 3,67 ± 2,86 and it was 72,10 ± 16,89 in those over 14 yr group. The base illness registered more frequently was the neurological disorders in 2,732 (41,77%) patients, followed by cancer patients in 1,838; 28,10%. The enteral access route was registered in 1,123 (17,17%) of the episodes, being more frequent the administration by nasogastric tube 562 (50,04%). The mean length of nutritional treatment by episode was 323 days (10,77 months). 606 episodes of HEN ended, being the principal reasons for discontinuing treatment the patient death in 295 (48,68%) occasions. The transition to oral feeding occurred in 219 (36,14%) cases. Patients maintained normal activity in 2162 (32,55%) HEN episodes and 2,468 (37,13%) cases were living "bed-couch". The level of dependence was "total" in 2,598 (39,07%) of the episodes recorded. The nutritional formula was provided by the hospital in 4,183 (62,91%) cases and by the reference pharmacy in 2,262 (el 34,02%). Consumables were provided by the hospital in 3,531 (53,11%) cases. Conclusions: The number of HEN patients recorded increased from the year 2008, continuing the gradual growth increase since the start of registration. The characteristics of the patients remain in the same profile as in previous years.

Objetivo: Exponer los resultados del registro de nutrición enteral domiciliaria (NED) del año 2008 del Grupo NADYA-SENPE. Material y métodos: Se recopilan los datos introducidosen el registro desde el 1 de enero al 31 de diciembre de 2008. Resultados: Durante este periodo se registraron 6.206 pacientes (51% varones) y un total de 6.279 episodios de NED en 31 hospitales españoles. El 95% de los enfermos tenía más de 14 años. La edad media (± desviación estándar) de los menores de 14 años fue de 4,83 años (± 3,29) y la de los mayores de 70,75 años (± 18,14). Las enfermedades que con más frecuencia motivaron el uso de la NED fueron la patología neurológica (39%) y las neoplasias (27%). La vía de administración más utilizada fue la oral (43,4%), seguida de la sonda nasoenteral (40,4%) y la gastrostomía (14,7%). La duración media del soporte fue de 305,36 días (10 meses). Los motivos más frecuentes de la finalización del tratamiento fueron la muerte del paciente (43%) y el paso a vía oral (40%). El nivel de actividad de los pacientes fue normal sólo en el 33% de ellos y limitado en diverso grado en el resto. La mayoría requería ayuda (parcial 25% o total 38%). El suministro de la fórmula de NE se realizó mayoritariamente en el Hospital (65%) y en el 32 % se efectuó a través de las oficinas de farmacia. La provisión del material fungible se efectuó a través de los hospitales en el 82,4% de los casos y en atención primaria en el 17,2%. Conclusiones: El número de pacientes registrados y su edad aumentan en relación con los años anteriores, pero se mantiene con pequeñas variaciones el resto de las variables analizadas. El aumento de la duración del soporte puede estar artefactado por el tipo de cumplimentación del registro.Aim: To present the results of the Spanish home enteral nutrition (HEN) registry of the year 2008 from the NADYA-SENPE group. Material and methods: We recorded the HEN registry data from January 1st to December 31st 2008. Results: The number of patients registered in this period was 6206 (51% male) with up to 6,279 episodes of HEN, from 31 Spanish hospitals. Most of the patients (95%) were older than 14 yr. Mean age was 4.83 ± 3.29 yr in the children group, and 70.75 ± 18.14 yr in the adult group (older than 14 yr). Neurological disorders (39%) and cancer (27%) were the two most prevalent diagnoses. The oral route was the most frequently used (43,4%), followed by nasogastric tube (40,4%), and gastrostomy tube (14,7%). Mean length of treatment was 305,36 days (10 months). The principal reasons for discontinuing treatment were death (43%) and progress to oral diet (40%). Only 33% of the patients had a normal activity level, being limited in different grades in the rest of the patients. Most of the patients required partial (25%) or total help (38%). The enteral formula was provided by the hospital in 65% of the cases and by private pharmacies in 32%. The disposables were provided by the hospital (82,4%) and primary care services (17,2%). Conclusions: The number and the age of the patients registered have increased comparing to previous years, with little variations in the rest of analyzed variables. The increase in the length of treatment could reflect misreporting of the weaning process in the registry.

Objetivo: Comunicar los resultados obtenidos en el registro de Nutrición Parenteral Domiciliaria (NPD) del grupo NADYA-SENPE en los años 2004-2005. Material y métodos: Recopilación de los datos del nuevo registro "on-line" de NPD del grupo NADYA-SENPE en el período 2004-2005. Resultados: Durante el año 2004 se registraron 70 pacientes con NPD (23 hombres y 47 mujeres) pertenecientes a 14 centros hospitalarios. La edad media de los pacientes mayores de 14 años fue de 53,7 ± 14,87 años (m ± DS) y de 6 ± 2,83 años para los menores de 14 años. La enfermedad de base más frecuente fue la neoplasia (24%) seguida de la isquemia mesentérica (19%). Los catéteres más utilizados fueron los tunelizados (75%). Las complicaciones más frecuentes fueron las sépticas relacionadas con el catéter, con una tasa de 0,98 infecciones/ 103 días. El tiempo de soporte nutricional fue superior a dos años en el 69% de los casos. El suministro de las soluciones de NPD y del material fungible fue proporcionado por las farmacias hospitalarias en el 81% y el 83%, respectivamente. El 54% de los pacientes presentaban un nivel de actividad normal. En la mayoría de los pacientes la causa de finalización de la NPD fue la transición a la dieta oral (41%), o el fallecimiento (28%). Durante el año 2005 se registraron 79 pacientes con NPD (33 hombres y 46 mujeres), pertenecientes a 14 centros hospitalarios. La edad media de los mayores de 14 años fue de 52,39 ± 14,21 años y de 6,5 ± 5,21 años para los menores de 14 años. La enfermedad de base más frecuente fue la neoplasia (22%), seguida de la isquemia mesénterica (15%). El 63% de los pacientes utilizaron catéteres tunelizados. Las complicaciones más frecuentes fueron las sépticas relacionadas con el catéter (1,14 infecciones/ 10³ días). El tiempo de soporte nutricional fue mayor a dos años en un 51% de los pacientes. El suministro de las soluciones de NPD y del fungible fue en el hospital en el 76% y 81%, respectivamente. El nivel de actividad de los pacientes con NPD fue normal en el 50%. Los motivos más frecuentes de finalización del tratamiento fueron la transición a dieta oral/ enteral (41%) y el fallecimiento (31%). Conclusiones: Hemos observado un ligero descenso en el número de pacientes registrados con NPD durante el período 2004-2005, posiblemente en relación con el cambio del registro. Las características generales de los pacientes son similares a las de años anteriores. Se aprecia un aumento en la tasa de complicaciones sépticas relacionadas con el catéter en el año 2005.Objective: To report the results of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group of the years 2004 and 2005. Material y methods: We summarized the data of the new on-line HPN registryof the NADYA-SENPE group for the period 2004-2005. Results: During the year 2004, 70 HPN-patients (23 males and 47 females) were registered from 14 hospitals. Mean age of adults was 53,7 ± 14,87 years (m ± SD) and 6 ± 2,83 years for those younger than 14 years. The most frequent etiologies of the intestinal failure were neoplasia (24%) and mesenteric ischaemia (19%). Tunnelled catheters were used in 75% of the patients. The catheterrelated infections were the most frequent complications, with a rate of 0,98 episodes/103 days. In 69% of the cases the nutritional support was maintained for more than 2 years. HPN solutions and disposables were supplied by the hospital pharmacy in 81% and 83%, respectively. Up to 54% of the patients had a normal activity level. The most frequent reasons to end HPN treatment were the transition to oral intake (41%), or exitus (28%). During the year 2005, 79 patients (33 males and 46 females) were registered from 14 hospitals. Mean age of adults was 52,39 ± 14,21 years and 6,5 ± 5,21 years for those younger than 14 yrs. The most frequent etiologies of the intestinal failure were neoplasia (22%), and mesenteric ischaemia (15%). Tunnelled catheters were used in 63% of the patients. The catheter-related infections were the most frequent complications, with a rate of 1,14 episodes/10³ days. In 51% of the cases the nutritional support was maintained for more than 2 years. HPN solutions and disposables were supplied by the hospital pharmacy in 76% and 81%, respectively. Up to 50% of the patients had a normal activity level. The most frequent reasons to end HPN treatment were the transition to oral/enteral feeding (41%) and exitus (31%). Conclusions: We have observed a mild decrease in the number of HPN patients registered in the period 2004-2005, probably related to the change of the registry. The characteristics of the patients are similar to previous years. We have observed an increase in the septic catheterrelated complications in the year 2005.

Objetivos: La cirugía bariátrica ha demostrado su eficacia en pérdida de peso y reducción de comorbilidades en el obeso mórbido. Los objetivos de nuestro trabajo fueron: evaluar los resultados con las técnicas de Scopinaro y Bypass gástrico, mediante cirugía abierta y laparoscópica. Material y métodos: 78 pacientes con obesidad mórbida intervenidos desde el año 2000 al 2005. 50 pacientes fueron intervenidos por cirugía abierta y 28 por laparoscopia. Se realizó bypass gástrico en 54 pacientes, la técnica Scopinaro en 20 y gastroplastia vertical anillada en 3. El tiempo de seguimiento fue desde 6 y 60 meses. Se recogieron los resultados obtenidos con las diversas técnicas y vías quirúrgicas. Resultados: El porcentaje de pacientes con pérdida de exceso de peso inferior al 50% a los dos años fue del 5% y del 13%, y superior al 75% fue del 55% y del 40% en el bypass gástrico y el Scopiraro respectivamente. Todas las comorbilidades mejoraron significativamente. La estancia media fue inferior (p < 0,001) en el caso de laparoscopia. Las complicaciones no nutricionales fueron en su mayoría superiores en la cirugía abierta destacando las eventraciones (30%), infección de las herida (32%), y complicaciones respiratorias (16%). Las complicaciones nutricionales fueron superiores en la técnica Scopinaro destacando el déficit de vitamina D (50%), Zinc (25%), magnesio (10%) y albúmina (5%). Conclusiones: En nuestra experiencia, la realización del bypass gástrico por laparoscopia, consigue menor estancia media, menores complicaciones nutricionales y quirúrgicas, sin diferencias significativas con respecto al Scopinaro en cuanto a pérdida de peso y reducción de comorbilidades. Sin embargo, para poder defender esta técnica como de elección se requieren estudios de mayor tamaño, controlados y aleatorizados y a más largo plazo, teniendo siempre en cuenta la experiencia de nuestros cirujanos.Objetives: Bariatric surgery has demonstrated its efficacy in weight loss and in reducing the comorbidities in the morbid obesity patient. The objectives of this study were to analyze the effectiveness and complication of the Scopinaro and gastric bypass techniques as well as the results from open surgery verses laparoscopy. Design: Retrospective study from 1999-2005. Subject and methods: 78 patients with morbid obesity were operated. 50 patients underwent open surgery and 28 underwent laparoscopy. Gastric bypass was performed in 54 patients, Scopinaro was performed in 20 patients and Vertical Banded Gastroplasty (VBG) was performed in 3 patients. The follow up time was between 6 and 60 months. The results obtained with Scopinaro and gastric bypass were compared as well as the results from open surgery verses laparoscopy. Results: The percentage of patients with a percent of excess weight loss under 50% in two years was of 5% and 13%, and the excess weight loss over 75% was of 55% ad 40% in the gastric bypass and the Scopinaro technique respectively. All the comorbidities improved.The average stay was decreased in the case of laparoscopy.The non-nutritional complications were increased for most cases in open surgery with the emphasis in eventrations, infections of the wound and respiratory complications. The nutritional complications were superior with Scopinaro´s technique. Conclusions: Based on our study, we would recommend the performance of gastric bypass for laparoscopy due to the reduced average stay and less nutritional and surgical complications. The literature results vary and therefore we consider necessary further control and random studies to correctly establish these comparisons.

La fístula linfática es una complicación con una incidencia considerable en los pacientes sometidos a una disección cervical. Su aparición puede conducir a serios problemas respiratorios y nutricionales. El tratamiento de esta patología ha sido y es en la actualidad debatido entre los diversos especialistas implicados. En las últimas revisiones parece existir consenso en tratar de forma conservadora la mayoría de ellas. Dentro del tratamiento médico conservador, la dieta baja en triglicéridos de cadena larga, es una parte fundamental.Chylous fistula after neck dissection is a welldescribed complication. This pHatology can lead to serious respiratory and nutritional complications. Therapeutical options for chylous fistula remains controversial. On last reviews, there are an agreement on the conservative management. Within of this management, low long-chain triglycerides fat diet is an essential part.

Objetivo: Exponer los resultados del registro de nutrición enteral domiciliaria (NED) del año 2008 del Grupo NADYA-SENPE. Material y métodos: Se recopilan los datos introducidosen el registro desde el 1 de enero al 31 de diciembre de 2008. Resultados: Durante este periodo se registraron 6.206 pacientes (51% varones) y un total de 6.279 episodios de NED en 31 hospitales españoles. El 95% de los enfermos tenía más de 14 años. La edad media (± desviación estándar) de los menores de 14 años fue de 4,83 años (± 3,29) y la de los mayores de 70,75 años (± 18,14). Las enfermedades que con más frecuencia motivaron el uso de la NED fueron la patología neurológica (39%) y las neoplasias (27%). La vía de administración más utilizada fue la oral (43,4%), seguida de la sonda nasoenteral (40,4%) y la gastrostomía (14,7%). La duración media del soporte fue de 305,36 días (10 meses). Los motivos más frecuentes de la finalización del tratamiento fueron la muerte del paciente (43%) y el paso a vía oral (40%). El nivel de actividad de los pacientes fue normal sólo en el 33% de ellos y limitado en diverso grado en el resto. La mayoría requería ayuda (parcial 25% o total 38%). El suministro de la fórmula de NE se realizó mayoritariamente en el Hospital (65%) y en el 32 % se efectuó a través de las oficinas de farmacia. La provisión del material fungible se efectuó a través de los hospitales en el 82,4% de los casos y en atención primaria en el 17,2%. Conclusiones: El número de pacientes registrados y su edad aumentan en relación con los años anteriores, pero se mantiene con pequeñas variaciones el resto de las variables analizadas. El aumento de la duración del soporte puede estar artefactado por el tipo de cumplimentación del registro.

Introduction: Bariatric surgery has been shown to be an effective therapy for weight loss in patients with severe obesity, and the implementation of a multidisciplinary management protocol is recommended. Objectives: To assess the usefulness of the implementation of a management protocol in obesity surgery based on the Spanish Consensus Document of the SEEDO. Methods: Retrospective comparative study of the outcomes in patients previously operated (51 patients) and after the implementation of the protocol (66 patients). The following data were gathered: anthropometry, pre-and post-surgery comorbidities, post-surgical nutritional and surgical complications, validated Quality of Life questionnaire, and dietary habits. Results: Withdrawals (17.6%) and alcoholism (5.8%) were higher in patients pre- versus post-implementation of the protocol (4.5% vs. 3%, respectively), the differences being statistically significant. The mortality rate was 2% in the pre-protocol group and 0% in the post-protocol group. The dietary habits were better in the post-protocol group, the pre-protocol group presenting a higher percentage of feeding-behavior disorders (5.1%) although not reaching a statistical significance. The improvement in quality of life was higher in the post-protocol group for all items, but only reaching statistical significance in sexual activity (p = 0.004). In the pre-protocol group, 70.5% of the patients had more than one nutritional complication vs. 32.8% in the post-protocol group (p < 0.05). There were no differences regarding the percentage of weight in excess lost at two years (> 50% in 81.3% in the pre-protocol group vs. 74.8% in the pos-protocol group) or the comorbidities. Conclusions: Bariatric surgery achieves excellent outcomes in weight loss, comorbidities, and quality of life, but presents nutritional, surgical, and psychiatric complications that require a protocol-based and multidisciplinary approach. Our protocol improves the outcomes regarding the withdrawal rates, feeding-behavior disorders, dietary habits, nutritional complications, and quality of life. [ABSTRACT FROM AUTHOR]

Objetivo: Comunicar los datos del registro de Nutrición Parenteral Domiciliaria (NPD) del grupo de trabajo NADYA-SENPE del año 2006. Material y métodos: Recopilación de los datos del registro "on-line" introducidos desde el 1 de enero al 31 de diciembre de 2006. Resultados: Se registraron 103 pacientes con NPD (47 hombres y 56 mujeres), pertenecientes a 19 centros hospitalarios. Edad media: 53,3 ± 14,9 años (para los 91 pacientes ≥ 14 años, y 2 ± 0 años (para los 12 pacientes > 14 años). Patología más frecuente: neoplasia (29%) seguida de alteraciones de la motilidad intestinal (13%). Motivo de indicación: 40% síndrome de intestino corto, seguido de obstrucción intestinal (22%) y malabsorción (21%). Catéteres más utilizados: tunelizados (45%) y reservorios subcutáneos (32%). Complicaciones mas frecuentes: sépticas relacionadas con el catéter (0,85 infecciones por cada mil días de NPD). Duración de la NPD: > 2 años en el 50% de casos. Al acabar el año seguía en activo el 70,9% de los pacientes; la muerte fue la principal causa de la finalización de la NPD (53%). El 52% de los pacientes recibíeron alimentación oral o enteral complementaria. El 48% de los pacientes tenían un nivel de actividad normal, siendo autónomos el 55% del total. El hospital suministró la formula de NP en el 82% de los casos y el material fungible en el 78%. Se consideraron candidatos a trasplante intestinal el 27% de los pacientes. Conclusiones: Se observa un aumento de los pacientes registrados respecto a años anteriores con una prevalencia muy variable según comunidades autónomas. La principal patología sigue siendo la neoplasia, que ocupa el primer lugar desde 2003. Se aprecia una disminución de las complicaciones sépticas relacionadas con el catéter respecto a 2004 y 2005.Objective: To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the year 2006. Methodology: We compiled the data from the on-line registry introduced by the responsible Units for the monitoring of HPN from January 1st to December 31st 2006. Results: 103 patients with HPN were registered (47 males and 56 females), belonging to 19 hospitals. Average age for the 91 patients older than 14 years old was 53.3 ± 14.9 years old, and that for the 12 patients under 14 years old was 2 ± 0 years old. Most frequent pathology was neoplasm (29%), followed by intestinal motility disorders (13%). The reason for HPN provision was short bowel syndrome (40%), intestinal obstruction (22%), and malabsorption (21%). Tunneled catheters were mostly used (45%), followed by implanted port-catheters (32%). Catheter related infections were the most frequent complications, with a rate of 0.85 episodes / 103 days. HPD was provided for more than two years in 50% of the cases. By the end of 2006, 70.9% of the patients remained active; exitus was the most frequent reason to end HPN (53%). Complementary oral or enteral nutrition was provided to 52% of the patients. 48% of the patients had a normal activity level, and a 55% were autonomous. PN formula was supplied by the hospital in 82% of the cases, while this number was 78% for fungible materials. 27% of the patients were eligible for intestinal transplant. Conclusions: We observe an increase in registered patients with respect to previous years, with a very different prevalence among regions. Neoplasia remains as the main pathology since 2003. We observe a decrease in catheter-related infections with respect to the 2004-2005 period.

Alerts are a common functionality of clinical decision support systems (CDSSs). Although they have proven to be useful in clinical practice, the alert burden can lead to alert fatigue and significantly reduce their usability and acceptance. Based on a literature review, we propose a unified framework consisting of a set of meaningful timestamps that allows the use of state-of-the-art measures for alert burden, such as alert dwell time, alert think time, and response time. In addition, it can be used to investigate other measures that could be relevant as regards dealing with this problem. Furthermore, we provide a case study concerning three different types of alerts to which the framework was successfully applied. We consider that our framework can easily be adapted to other CDSSs and that it could be useful for dealing with alert burden measurement thus contributing to its appropriate management., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

In the adult mammalian brain, most neural stem cells (NSCs) are held in a reversible state of quiescence, which is essential to avoid NSC exhaustion and determine the appropriate neurogenesis rate. NSCs of the mouse adult subependymal niche provide neurons for olfactory circuits and can be found at different depths of quiescence, but very little is known on how their quiescence-to-activation transition is controlled. Here, we identify the atypical cyclin-dependent kinase (CDK) activator RingoA as a regulator of this process. We show that the expression of RingoA increases the levels of CDK activity and facilitates cell cycle entry of a subset of NSCs that divide slowly. Accordingly, RingoA-deficient mice exhibit reduced olfactory neurogenesis with an accumulation of quiescent NSCs. Our results indicate that RingoA plays an important role in setting the threshold of CDK activity required for adult NSCs to exit quiescence and may represent a dormancy regulator in adult mammalian tissues., Competing Interests: The authors declare no competing interests., (© 2023 The Author(s).)

Introduction: Aim: to present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the years 2018 and 2019. Material and methods: from January 1, 2018 to December 31, 2019 the home enteral nutrition registry was recorded, and afterwards a further descriptive and analytical analysis was done. Results: in 2018, 4756 active patients were registered and the prevalence was 101.79 patients per one million inhabitants; in 2019 there were 4633 patients with a prevalence of 98.51 patients per one million inhabitants. They originated in 46 hospitals: 51.3 % were male, and median age was 71.0 years in both periods. The most frequent diagnosis was a neurological disorder that presents with aphagia or severe dysphagia - 58.7 % and 58.2 %, respectively. The main cause of episode termination was death. A total of 116 pediatric patients were registered in 2018 and 115 in 2019. Females represented 57.8 % and 59.1 %, respectively, in each of the periods. Median age at the beginning of HEN was 5 and 7 months. The most commonly recordered diagnostic group (42.2 % and 42.6 %) was included within the other pathologies group, followed by neurological disorders that present with aphagia or severe dysphagia in 41.4 % and 41.7 % of children. The route of administration was gastrostomy in 46.6 % and 46.1 %, respectively, in each of the periods. Conclusions: the NED registry of the NADYA-SENPE group continues to operate uninterruptedly since its inception. The number of registered patients and the number of participating hospitals remained stable in the last biennium analyzed.

Introduction: Aim: to communicate the home parenteral nutrition (HPN) data obtained from the HPN registry of the NADYA-SENPE group (www.nadya-senpe.com) for the year 2019. Material and methods: a descriptive analysis of the data collected from adult and pediatric patients with HPN in the NADYA-SENPE group registry from January 1 to December 31, 2019. Results: a total of 283 patients (51.9 % women), 31 children, and 252 adults from 47 Spanish hospitals were registered, which represents a prevalence rate of 6.01 patients per million inhabitants for year 2019. The most frequent diagnosis in adults was "palliative oncological" and "others" (21.0 %). In children, it was Hirschsprung's disease together with necrotizing enterocolitis, alterations in intestinal motility, and chronic intestinal pseudo-obstruction, with 4 cases each (12.9 %). The first reason for the indication was short-bowel syndrome in both children (51.6 %) and adults (37.3 %). The most used type of catheter was tunnelled both in children (75.9 %) and in adults (40.8 %). Sixty-eight episodes ended, all in adults, and the most frequent cause was death (54.4 %); 38.2 % were switched to oral. Conclusions: the number of collaborating centers and professionals in the NADYA registry is increasing. The main indications and reasons for HPN termination remain stable.

Cell survival in response to stress is determined by the coordination of various signaling pathways. The kinase p38α is activated by many stresses, but the intensity and duration of the signal depends on the stimuli. How different p38α-activation dynamics may impact cell life/death decisions is unclear. Here, we show that the p38α-signaling output in response to stress is modulated by the expression levels of the downstream kinase MK2. We demonstrate that p38α forms a complex with MK2 in nonstimulated mammalian cells. Upon pathway activation, p38α phosphorylates MK2, the complex dissociates, and MK2 is degraded. Interestingly, transient p38α activation allows MK2 reexpression, reassembly of the p38α-MK2 complex, and cell survival. In contrast, sustained p38α activation induced by severe stress interferes with p38α-MK2 interaction, resulting in irreversible MK2 loss and cell death. MK2 degradation is mediated by the E3 ubiquitin ligase MDM2, and we identify four lysine residues in MK2 that are directly ubiquitinated by MDM2. Expression of an MK2 mutant that cannot be ubiquitinated by MDM2 enhances the survival of stressed cells. Our results indicate that MK2 reexpression and binding to p38α is critical for cell viability in response to stress and illustrate how particular p38α-activation patterns induced by different signals shape the stress-induced cell fate., Competing Interests: The authors declare no competing interest.

Antimicrobial Susceptibility Tests (ASTs) are performed in hospitals to detect whether an infectious agent is resistant or susceptible to a set of antimicrobials. When AST results are available, the evaluation of the patient's antimicrobial therapy is a critical task to ensure its effectiveness against the found microorganism. Since not all the available antimicrobials can be tested in ASTs, clinicians rely on their expert knowledge to complement AST results and prescribe the most appropriate antimicrobials for each infection. Our goal is to help physicians in this task by improving the detection of antimicrobial therapies at risk of failure by Clinical Decision Support Systems (CDSSs). With this aim, we have incorporated the EUCAST expert rules in antimicrobial susceptibility testing into a CDSS to improve the results of ASTs. In order to achieve this, we have combined both ontologies and production rules. Furthermore, we have evaluated the impact of EUCAST expert rules on the detection of antimicrobial therapies at risk of failure. We performed a retrospective study with one year of clinical data, obtaining a total of 148 alerts from which 62 (41.9%) were based on the additional expert knowledge. Furthermore, the evaluation of the clinical relevance of 27 alerts resulted in 8 of them (29.7%) being clinically relevant. Of these, 6 were based on expert knowledge. Finally, an alarm fatigue study suggests that waiting between 48 and 72 h from the reception of the AST results can significantly reduce the number of alerts that are unnecessary in our CDSS because they are already being addressed in the hospital's daily workflow. In conclusion, we demonstrate that the incorporation of expert knowledge improves the capabilities of CDSSs as regards detecting the risk of antimicrobial therapy failure, which may improve the institutional outcomes in antimicrobial stewardship., (Copyright © 2019 Elsevier Inc.

Introduction: Objective: to present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the year 2016 and 2017. Material and methods: from January 1st 2016 to December 31st 2017, the HEN registry was recorded and afterwards a further descriptive and analytical analysis was done. Results: in 2016, 4,578 active patients were recorded and prevalence was 98.33 patients per one million inhabitants; in 2017, 4,777 patients were recorded, with a prevalence of 102.57 per one million inhabitants; 50.8% were males in 2016 and 50.5% in 2017. During the period 2016-17, median age was 71.5 years (IIQ 57-83), 1,558 HEN episodes were finished and the main cause was death (793 patients, 50.89%). Adult males were younger than females (65.3 vs. 73.3 years, p-value < 0.001). The most frequent diagnosis was the neurological disorder that presents with aphagia or severe dysphagia (59%). Nasogastric tube was the most frequent administration route (48.3%) and it is the most widely used in elderly patients (p < 0.001). One hundred and twenty-six pediatric patients were registered (57.1% females). Median age at the beginning of HEN in children was four months. "Other disorders" was the most recorded diagnostic group (41.3%), followed by the group of neurological disorder that presents with aphagia or severe dysphagia. Regarding children, 57.6% were fed through gastrostomy and the younger ones were fed through nasogastric tube (p-value 0.001). Conclusions: the number of patients in the registry, as well as the number of participating centers, is progressively increasing. The main characteristics of the patients have not changed. Despite the increase in diagnostic possibilities in the pediatric population, the classification within the group of "Other pathologies" is quite significant.

Breast cancer is the second leading cause of cancer-related death among women. Here we report a role for the protein kinase p38α in coordinating the DNA damage response and limiting chromosome instability during breast tumor progression, and identify the DNA repair regulator CtIP as a p38α substrate. Accordingly, decreased p38α signaling results in impaired ATR activation and homologous recombination repair, with concomitant increases in replication stress, DNA damage, and chromosome instability, leading to cancer cell death and tumor regression. Moreover, we show that pharmacological inhibition of p38α potentiates the effects of taxanes by boosting chromosome instability in murine models and patient-derived xenografts, suggesting the potential interest of combining p38α inhibitors with chemotherapeutic drugs that induce chromosome instability., (Copyright © 2018 Elsevier Inc.

Objective: To present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the years 2014 and 2015. Methods: From January 1st 2014 to December 31st 2015 the HEN registry was recorded and afterwards a further descriptive and analytical analysis was done. Results: In 2014, 3749 patients were recorded, and 4202 in 2015; prevalence was 80.58 patients/one million inhabitants in Spain in 2014 and 90.51 in 2015. There were 49.9% females in 2014 and 50.3% in 2015. Median age was 73 years (IQI 59-83) in 2014 as well as in 2015. 684 episodes finished in 2014 and 631 in 2015, with death as the main cause, in 54.9% and 50.4%, respectively. The ones who were fed through nasogastric tube had a mean age higher than the ones fed by any other route (p-value < 0.001). Sisty-seven paediatric patients were recorded in 2014 (56.7% females) and 77 in 2015 (55.8% females). Median age at the beginning of HEN among children was 5 months in 2014 and 5 months in 2015. The main route of administration was gastrostomy, in 52.5% in 2014 and nasogastric tube in 50.8% in 2015. 7 episodes finished in 2014 and 13 in 2015, having death as the main cause (57.1% in 2014 and 38.5% in 2015). It was found that were younger children the ones who were mainly fed by nasogastric tubes (p-value 0.004 vs. 0.002). Among paediatric patients as well as adults, the main diagnosis leading to HEN was neurological disease which gives aphagia or severe dysphagia. Conclusions: There has been an increase in the number of patients in the registry as well as the participating centers and the number of patients per center, without any significant change in the characteristics of the patients other than longer duration of the episodes.

Aim: To present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the year 2013., Material and Methods: From January 1st to December 31st 2013 data was recorded for the HEN registry and further descriptive and analytical analysis was done., Results: In this period 3 223 patients (50.6% men) and a total of 3 272 episodes of HEN were registered in 33 Spanish hospitals. The rate of prevalence was of 67,11 patients/million habitants/ year 2013. A high percentage of patients (98,24%) were older than 14 years. Adult's mean age was 69,14 years (sd 17,64) and men were younger than women p-value <0,001. Children mean age was 2,38 years (sd 4,35). The most frequent indication for HEN was neurological disease for children (49,1%). and for adults (60,6%). Gastrostomy was the most used administration route for children (51%) while younger ones were fed with NGT (p-value 0,003) also older adults (48%) were fed with this type of tube (p-value <0,001). The most frequent reasons for cessation of treatment was death, 44,4% were children and 54,7% were adults., Conclusions: The number of patients and hospitals registered increased in the last years while the other variables maintain steady. The registry developed allowing contrasted analysis of data in order to get more information., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

Objective: To describe the results of the home enteral nutrition (HEN) registry of the NADYA-SENPE group in 2011 and 2012., Material and Methods: We retrieved the data of the patients recorded from January 1st 2011 to December 31st 2012., Results: There were 3021 patients in the registry during the period from 29 hospitals, which gives 65.39 per million inhabitants. 97.95% were adults, 51.4% male. Mean age was 67.64 ± 19.1, median age was 72 years for adults and 7 months for children. Median duration with HEN was 351 days and for 97.5% was their first event with HEN. Most patients had HEN because of neurological disease (57.8%). Access route was nasogastric tube for 43.5% and gastrostomy for 33.5%. Most patients had limited activity level and, concerning autonomy, 54.8% needed total help. Nutritional formula was supplied from chemist's office to 73.8% of patients and disposables, when necessary, was supplied from hospitals to 53.8% of patients. HEN was finished for 1,031 patients (34.1%) during the period of study, 56.6% due to decease and 22.2% due to recovery of oral intake., Conclusions: Data from NADYA-SENPE registry must be explained cautiously because it is a non-compulsory registry. In spite of the change in the methodology of the registry in 2010, tendencies regarding HEN have been maintained, other than oral route., (Copyright AULA MEDICA EDICIONES 2014.

Objectives: To assess control of blood glucose and other cardiovascular risk factors in diabetic patients monitored at an outpatient endocrinology clinic. To ascertain treatment used and its changes over time., Patients and Methods: A cohort of 424 randomly selected diabetic patients (both type 1 and type 2) was monitored from 2004 to 2008. Final cohort size was 343 patients. Data were collected about epidemiological characteristics, cardiovascular risk factors, chronic complications, glycemic, lipid and blood pressure control, and treatment at baseline and 4 years., Results: After 4 years, the proportion of patients achieving glycosylated hemoglobin levels less than 7% remained stable (type 1: 18.5% in 2004 vs 21.7% in 2008, type 2: 26.6% vs 26.5%). The degree of achievement of lipid and blood pressure (BP) control levels increased in both groups. The complexity of treatment schemes used to achieve these results significantly increased., Conclusions: Stabilization of glycemic control after 4 years of follow-up was a positive result, considering the long course of diabetes, progressive pancreatic function impairment, and complexity of our cohort. Treatment optimization significantly improved BP and lipid control in the study group., (Copyright © 2011 SEEN. Published by Elsevier Espana. All rights reserved.)

Objectives: To report the Group Registry NADYASENPE data about home parenteral nutrition (HPN) in Spain in 2010., Material and Methods: A descriptive study of the database of the national registry of HPN of NADYA-SENPE (December 10, 2009 to December 10, 2010). For the calculation of prevalence the latest data published by the Institute National Statistics Office (01/01/2009) was used., Results: There were registered 148 patients from 23 hospitals, 86 women (58.11%) and 9 children (6.08%). The average age of the 139 patients older than 14 years was 53.06 ± 15.41 years. The average duration of HPN was 316.97 days/patient. The most common diagnosis in those younger than 14 years was short bowel traumatic with 5 cases (55.55%) and in those older than 14 years, palliative care cancer with 29 cases (19.59%). The reason for the indication for HPN was short bowel syndrome in 74 cases (47%). The access via most frequently recorded was tunneled catheter in 36 cases (22.78%) followed by implanted port-catheters in 13 cases (8.23%) and other pathways in 3 cases (1.90%). There were 23 catheterrelated infections (82.14%) which represented 0.49 /1,000 days of PN, all of which occurred in cases older than 14 years. During the year 24 episodes of HPN ended, the most frequent cause was the transition to oral nutrition in 12 episodes (50%). It was reported that patients had a normal activity in 70 episodes of HPN (44.30%) with complete autonomy in 88 episodes (55.69%). Some patients 39 (24.68%) were potential candidates for intestinal transplantation., Conclusions: The number of registered patients is slightly lower than the previous year, although the number of participating hospitals is the same. The most frequent complication remains catheter-related infection but its incidence has decreased from previous years, presenting the lowest rate since the creation of the record. Differences in participation in the registry observed in the Autonomous Communities causes the development of implementation strategies. There is a gradual increase in day length of HPN over the years, which suggests the chronic treatments of some patients and obliges to study the existence of a possible confounding factor, in case there is an oversight of closing an episode. Therefore, it is necessary to update the registry with warning systems that facilitate periodic review of the patients and optimize the validity of registration.

Background and Aims: Differentiated thyroid carcinoma (DTC) is the most common endocrine tumor. DTC has a good prognosis and survival rates higher than 85%. The aim of our study was to assess our current survival rate and to analyze prognostic factors., Patients and Methods: A retrospective analysis was conducted of 308 patients with DTC (93.5% with papillary tumors, 78.8% women). Mean age at diagnosis was 45.4±15.8years, and mean follow-up time was 8.9±6.8years. The whole group was treated and followed up using the same protocol at our hospital. The following data were collected: age at diagnosis, sex, histology, TNM stage, treatments, and date and cause of death. Survival probability was calculated using Kaplan-Meier analyses. Prognostic factors were analyzed using a univariate log rank test and a multivariate Cox regression analysis model., Results: Twenty-six patients died during follow-up, 15 of them (4.9%) from DTC. Thyroid carcinoma-related survival was 92.7% for the whole group. In multivariate analyses, the following parameters were associated to a significantly increased risk of death from DTC: presence of distant metastases, follicular histology, age at diagnosis older than 60years, and extrathyroid invasion., Discussion: Our survival rate is similar to that reported in literature. Assessment of prognostic factors related to an increased risk of death in our patient group, is essential to establish active therapeutic approaches in high risk patients., (Copyright © 2010 SEEN.

Introduction: Bariatric surgery has been shown to be an effective therapy for weight loss in patients with severe obesity, and the implementation of a multidisciplinar management protocol is recommended., Objectives: To assess the usefulness of the implementation of a management protocol in obesity surgery based on the Spanish Consensus Document of the SEEDO., Methods: Retrospective comparative study of the outcomes in patients previously operated (51 patients) and after the implementation of the protocol (66 patients). The following data were gathered: anthropometry, pre-and post-surgery comorbidities, post-surgical nutritional and surgical complications, validated Quality of Life questionnaire, and dietary habits., Results: Withdrawals (l7.6%) and alcoholism (5.8%) were higher in patients pre- versus post-implementation of the protocol (4.5% vs. 3%, respectively), the differences being statistically significant. The mortality rate was 2% in the pre-protocol group and 0% in the postprotocol group. The dietary habits were better in the post-protocol group, the pre-protocol group presenting a higher percentage of feeding-behavior disorders (5.1%) although not reaching a statistical significance. The improvement in quality of life was higher in the post-protocol group for all items, but only reaching statistical significance in sexual activity (p = 0.004). In the pre-protocol group, 70.5% of the patients had more than one nutritional complication vs. 32.8% in the post-protocol group (p < 0.05). There were no differences regarding the percentage of weight in excess lost at two years (> 50% in 81.3% in the pre-protocol group vs. 74.8% in the pos-protocol group) or the comorbidities., Conclusions: Bariatric surgery achieves excellent outcomes in weight loss, comorbidities, and quality of life, but presents nutritional, surgical, and psychiatric complications that require a protocol-based and multidisciplinary approach. Our protocol improves the outcomes regarding the withdrawal rates, feeding-behavior disorders, dietary habits, nutritional complications, and quality of life.

Objective: To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the years 2007, 2008 and 2009., Methodology: We compiled the data from the on-line registry introduced by the responsible Units for the monitoring of HPN from January 1st 2007 to December 31st 2009. Included fields were: age, sex, diagnosis and reason for HPN, access path, complications, beginning and end dates, complementary oral or enteral nutrition, activity level, autonomy degree, product and fungible material supply, withdrawal reason and intestinal transplant indication., Results: 2007: 133 patients with HPN were registered (61 males and 72 females), belonging to 21 hospitals. Average age for the 119 patients older than 13 years old was 53.7 ± 14.9 years, and 3.6 ± 3.6 y. for the 14 patients under 14 years old. Most frequent pathology was neoplasm (24%), followed by intestinal motility disorders and actinic enteritis (14% both). The reason for HPN provision was short bowel syndrome (43%), malabsorption (27%), and intestinal obstruction (23%). Tunnelled catheters were mostly used (69%), followed by implanted port-catheters (27%). Catheter related infections were the most frequent complications, with a rate of 0.92 episodes/103 HPN days. HPN was provided for more than two years in 50% of the cases. By the end of 2007, 71.4% of the patients remained active; exitus was the most frequent reason to end HPN (57.5%). 26% of the patients were eligible for intestinal transplant. 2008: 143 patients with HPN were registered (62 males and 81 females), belonging to 24 hospitals. Average age for the 133 patients older than 13 years old was 54.7 ± 13.9 years, and 3.7 ± 0.6 y. for the 10 patients under 14 years old. Most frequent pathology was neoplasm (20%), followed by actinic enteritis (14%) and intestinal motility disorders (13% ). The reason for HPN provision was short bowel syndrome (44%), malabsorption (28%), and intestinal obstruction (20%). Tunnelled catheters were mostly used (60%), followed by implanted port-catheters (29%). Catheter related infections were the most frequent complications, with a rate of 0.50 episodes/10³ HPN days. HPN was provided for more than two years in 67% of the cases. By the end of 2008, 71.6% of the patients remained active; exitus was the most frequent reason to end HPN (52.4%). 29% of the patients were eligible for intestinal transplant. 2009: 158 patients with HPN were registered (62 males and 96 females), belonging to 24 hospitals. Average age for the 149 patients older than 13 years old was 55.2 ± 13.0 years. Most frequent pathology was neoplasm (25%), followed by actinic enteritis (12%) and intestinal motility disorders (11%). The reason for HPN provision was short bowel syndrome (42%), malabsorption, and intestinal obstruction (23% both). Tunnelled catheters were mostly used (60%), followed by implanted port-catheters (36%). Catheter related infections were the most frequent complications, with a rate of 0.67 episodes/10³ HPN days. HPN was provided for more than two years in 58% of the cases. By the end of 2009, 79.2% of the patients remained active; full oral nutrition was the most frequent reason to end HPN (48%). 23% of the patients were eligible for intestinal transplant., Conclusions: We observe an increase in registered patients with respect to previous years, with a very different prevalence among regions. Neoplasia remains as the main pathology since 2003. We observe a decrease in catheter-related infections in the last two years, being the 2008 rate the smallest since the register's beginning.

Objective: To describe the Home Enteral Nutrition Characteristics (HEN) recorded by the group NADYA-SENPE during 2009., Material and Method: collection and analysis of the data voluntary recorded in the HEN registry from the NADYA-SENPE group from January 1st to December 31st., Results: 6.540 HEN patients were registered, 5.11% more than the previous year and 6,649 episodes (3,135 in women, 47,93%) from 32 different hospitals. 6,238 of them (95,38%) were over 14 years. The mean age of the patients under 14 yr was 3,67 ± 2,86 and it was 72,10 ± 16,89 in those over 14 yr group. The base illness registered more frequently was the neurological disorders in 2,732 (41,77%) patients, followed by cancer patients in 1,838; 28,10%. The enteral access route was registered in 1,123 (17,17%) of the episodes, being more frequent the administration by nasogastric tube 562 (50,04%). The mean length of nutritional treatment by episode was 323 days (10,77 months). 606 episodes of HEN ended, being the principal reasons for discontinuing treatment the patient death in 295 (48,68%) occasions. The transition to oral feeding occurred in 219 (36,14%) cases. Patients maintained normal activity in 2162 (32,55%) HEN episodes and 2,468 (37,13%) cases were living "bed-couch". The level of dependence was "total" in 2,598 (39,07%) of the episodes recorded. The nutritional formula was provided by the hospital in 4,183 (62,91%) cases and by the reference pharmacy in 2,262 (el 34,02%). Consumables were provided by the hospital in 3,531 (53,11%) cases., Conclusions: The number of HEN patients recorded increased from the year 2008, continuing the gradual growth increase since the start of registration. The characteristics of the patients remain in the same profile as in previous years.

Background: Appropriate maternal intake of iodine during pregnancy is essential for maternal thyroxine production and thyroid status of the fetus. It should be possible to enhance iodine intake during pregnancy by using iodine fortified salt or taking iodine supplements. In the present report we determined the status of iodine nutrition in pregnant women who were stratified on the basis of their history of taking or not taking iodized salt or iodine supplements. The study was performed in Toledo (Spain), a region in which prior studies have noted borderline iodine sufficiency. Iodine nutrition was assessed by measuring urinary iodine concentration (UIC) and neonatal thyrotropin (TSH)., Methods: UIC was measured in 525 pregnant women. They were grouped according to their history of iodine intake. Diet Group 1 patients (n = 69) did not take iodized salt or iodine supplements during pregnancy. Diet Group 2 patients (n = 75) took iodized salt but not iodine supplements during pregnancy. Diet Group 3 patients (n = 381) took iodine supplements during pregnancy. Plasma determinations included TSH, free thyroxine, thyroid peroxidase antibody, and thyroglobulin antibody. UIC was measured in a single urine sample from all the pregnant women. Neonatal TSH was measured in capillary spot blood from all the neonates as part of a screening for congenital metabolic abnormalities., Results: The median UIC in all subjects was 164 μg/L (interquartile range [IR]: 116-245). The median UICs in Diet Groups 1, 2, and 3 were 134.5 (IR: 90-196), 146 (IR: 103-205), and 183 (IR: 124-261) μg/L, respectively (p = not significant [NS] for Diet Group 1 vs. 2; p < 0.01 for Diet Group 2 vs. 3; all other comparisons NS). The median (IR) TSH of the neonates in all Diet Groups was 1.0 (IR: 0.7-1.6) μU/mL. Only 2 neonates had blood TSH concentrations >5 mU/L. Neonatal blood TSH concentrations were similar in all Diet Groups., Conclusions: In a region with a history of borderline iodine deficiency the UICs were below 150 μg/L in a substantial percentage of pregnant women who did not take iodine supplements, regardless of whether or not they took iodized salt. Our results support the use of iodine supplements from the start of the pregnancy, or even before pregnancy in women who live in regions with a history of even small degrees of iodine deficiency. In addition, neonate TSH screening is not the best tool to assess whether the iodine status in populations is ideal.

Aim: To present the results of the Spanish home enteral nutrition (HEN) registry of the year 2008 from the NADYA-SENPE group., Material and Methods: We recorded the HEN registry data from January 1st to December 31st 2008., Results: The number of patients registered in this period was 6206 (51% male) with up to 6,279 episodes of HEN, from 31 Spanish hospitals. Most of the patients (95%) were older than 14 yr. Mean age was 4.83±3.29 yr in the children group, and 70.75±18.14 yr in the adult group (older than 14 yr). Neurological disorders (39%) and cancer (27%) were the two most prevalent diagnoses. The oral route was the most frequently used (43,4%), followed by nasogastric tube (40,4%), and gastrostomy tube (14,7%). Mean length of treatment was 305,36 days (10 months). The principal reasons for discontinuing treatment were death (43%) and progress to oral diet (40%). Only 33% of the patients had a normal activity level, being limited in different grades in the rest of the patients. Most of the patients required partial (25%) or total help (38%). The enteral formula was provided by the hospital in 65% of the cases and by private pharmacies in 32%. The disposables were provided by the hospital (82,4%) and primary care services (17,2%)., Conclusions: The number and the age of the patients registered have increased comparing to previous years, with little variations in the rest of analyzed variables. The increase in the length of treatment could reflect misreporting of the weaning process in the registry.

Solea senegalensis is a commercial flat fish traditionally farmed in earth ponds in coastal wetlands that might also become important to more intensive aquaculture. Gas bubble disease (GBD) is a potential risk for outdoor fish farming, particularly in certain periods of the year, related to improper management leading to macroalgae blooms. Physical-chemical conditions inducing hyperoxia, including radiation, temperature, and high levels of dissolved oxygen, have been monitored in fish affected by GBD together with observed symptoms. Exophthalmia, subcutaneous emphysemas, obstruction of gill lamellae, hemorrhages, and anomalous swimming were the main effects of oxygen supersaturation. A proteomic study was carried out for the first time under aquaculture conditions and protein expression changes are described for fish that were subject to hyperoxic conditions. Proteins identified in gill of GBD-affected fish are related to oxidative alteration of cytoskeleton structure/function (beta-tubulin, beta-actin), motility (light myosin chain, alpha-tropomyosin), or regulatory pathways (calmodulin, Raf kinase inhibitor protein), reflecting the central role of gill in oxygen exchange. Hepatic proteins identified are related to protein oxidative damages (beta-globin, FABPs), protection from oxidative stress (DCXR, GNMT), and inflammatory response (C3), in agreement with the predominant metabolic role of liver. Comparison of protein expression patterns and protein identification are suggested as potentially specific hyperoxia biomarkers that would facilitate prevention of GBD outbreaks.

Objective: To report the results of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group of the years 2004 and 2005., Material and Methods: We summarized the data of the new on-line HPN registry of the NADYA-SENPE group for the period 2004-2005., Results: During the year 2004, 70 HPN-patients (23 males and 47 females) were registered from 14 hospitals. Mean age of adults was 53,7 +/- 14,87 years (m +/- SD) and 6 +/- 2,83 years for those younger than 14 years. The most frequent etiologies of the intestinal failure were neoplasia (24%) and mesenteric ischaemia (19%). Tunnelled catheters were used in 75% of the patients. The catheter-related infections were the most frequent complications, with a rate of 0,98 episodes/10(3) days. In 69% of the cases the nutritional support was maintained for more than 2 years. HPN solutions and disposables were supplied by the hospital pharmacy in 81% and 83%, respectively. Up to 54% of the patients had a normal activity level. The most frequent reasons to end HPN treatment were the transition to oral intake (41%), or exitus (28%). During the year 2005, 79 patients (33 males and 46 females) were registered from 14 hospitals. Mean age of adults was 52,39 +/- 14,21 years and 6,5 +/- 5,21 years for those younger than 14 yrs. The most frequent etiologies of the intestinal failure were neoplasia (22%), and mesenteric ischaemia (15%). Tunnelled catheters were used in 63% of the patients. The catheter-related infections were the most frequent complications, with a rate of 1,14 episodes/10(3) days. In 51% of the cases the nutritional support was maintained for more than 2 years. HPN solutions and disposables were supplied by the hospital pharmacy in 76% and 81%, respectively. Up to 50% of the patients had a normal activity level. The most frequent reasons to end HPN treatment were the transition to oral/enteral feeding (41%) and exitus (31%)., Conclusions: We have observed a mild decrease in the number of HPN patients registered in the period 2004-2005, probably related to the change of the registry. The characteristics of the patients are similar to previous years. We have observed an increase in the septic catheter-related complications in the year 2005.

Objectives: Bariatric surgery has demonstrated its efficacy in weight loss and in reducing the comorbidities in the morbid obesity patient. The objectives of this study were to analyze the effectiveness and complication of the Scopinaro and gastric bypass techniques as well as the results from open surgery verses laparoscopy., Design: Retrospective study from 1999-2005., Subject and Methods: 78 patients with morbid obesity were operated. 50 patients underwent open surgery and 28 underwent laparoscopy. Gastric bypass was performed in 54 patients, Scopinaro was performed in 20 patients and Vertical Banded Gastroplasty (VBG) was performed in 3 patients. The follow up time was between 6 and 60 months. The results obtained with Scopinaro and gastric bypass were compared as well as the results from open surgery verses laparoscopy., Results: The percentage of patients with a percent of excess weight loss under 50% in two years was of 5% and 13%, and the excess weight loss over 75% was of 55% ad 40% in the gastric bypass and the Scopinaro technique respectively. All the comorbidities improved. The average stay was decreased in the case of laparoscopy. The non-nutritional complications were increased for most cases in open surgery with the emphasis in eventrations, infections of the wound and respiratory complications. The nutritional complications were superior with Scopinaro's technique., Conclusions: Based on our study, we would recommend the performance of gastric bypass for laparoscopy due to the reduced average stay and less nutritional and surgical complications. The literature results vary and therefore we consider necessary further control and random studies to correctly establish these comparisons.

Chylous fistula after neck dissection is a well-described complication. This pHatology can lead to serious respiratory and nutritional complications. Therapeutical options for chylous fistula remains controversial. On last reviews, there are an agreement on the conservative management. Within of this management, low long-chain triglycerides fat diet is an essential part.

Objectives: To assess the concordance between corporal self-perception and BMI calculated in a population of volunteers., Secondary Objectives: to know the percentage of overweight, normoweight and obese individuals in this population., Subjects: The study includes 160 volunteers recruited at the Gómez Ulla and Severo Ochoa Hospitals in Madrid during the 4th edition of the "Obesity Day"., Actions: A total of 160 interviews were carried out, comprising a first group of 10 questions about how obesity is understood, how they classify themselves by self-perception (obese, overweight or normoweight individuals), the incidence of obesity in the family, living habits and the number of previous failed attempts to lose weight. In the case of a positive response to the last question, the survey is extended to 19 questions, analyzing the reasons, prescriptors, methods used, and weight loss results obtained., Results: The mean Body Mass Index (BMI) of the interviewees was 26.2 +/- 4.97 kg/m2, with 27.45 +/- 5.4 kg/m2 for males and 25.76 +/- 4.7 kg/m2 for women. Overweight men represented 32.5%, with 27.3% overweight women, while obese men accounted for 25.6% and obese women amounted to 20.6%. The differences were not significant between sexes, normoweight, overweight and obesity groups. The concordance between self-perception and BMI using the kappa index was 0,464 for the total sample, 0.229 for males and 0.527 for women, and according to the valuation scale proposed by Landis and Koch, it would correspond to a moderate degree of agreement for the population in general, medium for men and moderate for women., Conclusions: Overweight and obesity affect a high percentage of the Spanish population (almost 50%). Women show greater concern about being overweight, are more likely to participate in prevention campaigns, and present a corporal perception more in line with their true weight. Preventive campaigns should be implemented to reach the male population better, taking into account that this population presents a greater cardiovascular risk. It is important to place the problem of obesity in the right terms, without any "obesophobia" leading to disorders of the eating behaviour, while indicating the importance of the risk attributable to obesity and excess weight.
