Long-term studies comparing the mechanisms of different bariatric techniques for T2DM remission are scarce. We aimed to compare type 2 diabetes (T2DM) remission after a gastric bypass with a 200-cm biliopancreatic limb (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP), and to assess if the initial secretion of gastrointestinal hormones may predict metabolic outcomes at 5 years. Forty-five patients with mean BMI of 39.4(1.9)kg/m2 and T2DM with HbA1c of 7.7(1.9)% were randomized to mRYGB, SG, or GCP. Anthropometric and biochemical parameters, fasting concentrations of PYY, ghrelin, glucagon, and AUC of GLP-1 after SMT were determined prior to and at months 1 and 12 after surgery. At 5-year follow-up, anthropometrical and biochemical parameters were determined. Total weight loss percentage (TWL%) at year 1 and GLP-1 AUC at months 1 and 12 were higher in the mRYGB than in the SG and GCP. TWL% remained greater at 5 years in mRYGB group − 27.32 (7.8) vs. SG − 18.00 (10.6) and GCP − 14.83 (7.8), p = 0.001. At 5 years, complete T2DM remission was observed in 46.7% after mRYGB vs. 20.0% after SG and 6.6% after GCP, p

There is scant evidence of the long-term effects of bariatric surgery on bone mineral density (BMD). We compared BMD changes in patients with severe obesity and type 2 diabetes (T2D) 5 years after randomization to metabolic gastric bypass (mRYGB), sleeve gastrectomy (SG) and greater curvature plication (GCP). We studied the influence of first year gastrointestinal hormone changes on final bone outcomes. Forty-five patients, averaging 49.4 (7.8) years old and body mass index (BMI) 39.4 (1.9) kg/m2, were included. BMD at lumbar spine (LS) was lower after mRYGB compared to SG and GCP: 0.89 [0.82, 0.94] vs. 1.04 [0.91, 1.16] vs. 0.99 [0.89, 1.12], p = 0.020. A higher percentage of LS osteopenia was present after mRYGB 78.6% vs. 33.3% vs. 50.0%, respectively. BMD reduction was greater in T2D remitters vs. non-remitters. Weight at fifth year predicted BMD changes at the femoral neck (FN) (adjusted R2: 0.3218, p = 0.002), and type of surgery (mRYGB) and menopause predicted BMD changes at LS (adjusted R2: 0.2507, p &lt, 0.015). In conclusion, mRYGB produces higher deleterious effects on bone at LS compared to SG and GCP in the long-term. Women in menopause undergoing mRYGB are at highest risk of bone deterioration. Gastrointestinal hormone changes after surgery do not play a major role in BMD outcomes.

Endobarrier® is a minimally invasive, reversible endoscopic treatment for obesity. It provokes malabsorption along 60 cm of the small intestine, which can contribute to the development of vitamin deficiencies and to changes in bone mineral density (BMD). To determine the prevalence of nutrient deficiencies, changes in body composition and BMD during the first year after Endobarrier® placement. Twenty-one patients with type 2 diabetes met inclusion criteria. Levels of vitamins, micro and macronutrients were assessed prior and at 1, 3 and 12 months post-operatively. DEXA was performed before and 12 months after implant. Nineteen patients completed the 12 months follow-up. Vitamin D deficiency was the most prevalent finding before Endobarrier® implant. The percentage of patients with severe deficiency decreased from 19 to 5% at 12 months after supplementation. Microcytic anaemia was initially present in 9.5% of patients and increased to 26.3% at 12 months. Low ferritin and vitamin B12 levels were observed in 14.2 and 4.8% of patients before the implant and worsened to 42 and 10.5%. Low concentrations of magnesium and phosphorus were also common but improved along the study. A significant but not clinically relevant decrease in BMD of 4.14 ± 4.0% at the femoral neck was observed at 12 months without changes in osteocalcin levels. Vitamin deficiencies are common after Endobarrier® implant. It is therefore important to screen patients prior to and at regular intervals after the implant, and to encourage adherence to diet counselling and supplementation.

Resumen Introduccion Se ha definido un grupo de resecabilidad borderline resectable (APBR) en el adenocarcinoma de pancreas. El objetivo del estudio es evaluar los resultados en el tratamiento quirurgico tras neoadyuvancia del APBR. Metodo Entre 2010 y 2014 incluimos pacientes afectos de APBR en un protocolo de neoadyuvancia y cirugia, estadificados mediante tomografia computarizada multidetector (TCMD). El tratamiento con quimioterapia se baso en gemcitabina y oxaliplatino (GEMOX). Posteriormente, se realizo TCMD para descartar progresion, y se administro 5-FU en infusion y radioterapia concomitante. Se practico TCMD y reseccion en ausencia de progresion. Se realizo un estudio estadistico descriptivo, dividiendo la serie en grupo reseccion (grupo GR) y grupo progresion (grupo PROG). El seguimiento finalizo en febrero de 2016. Resultados Indicamos tratamiento neoadyuvante a 22 pacientes, 11 de ellos fueron finalmente intervenidos. Se realizaron 9 duodenopancreatectomias cefalicas, una duodenopancreatectomia total y una pancreatectomia corporocaudal. De los 11 pacientes, 7 requirieron algun tipo de reseccion vascular; 5 resecciones venosas, uno arterial y otro ambas. No hubo mortalidad postoperatoria, 7 (63%) tuvieron alguna complicacion y 4 fueron reintervenidos. La estancia hospitalaria postoperatoria mediana fue 17 dias (7-75). El estudio patologico evidencio margenes microscopicos libres (R0) en el 63% de los pacientes y ausencia de afectacion adenopatica en 10 pacientes (ypN0). Al cierre del estudio, todos los pacientes habian fallecido, con una supervivencia actuarial mediana de 13 meses (9,6-16,3). La supervivencia actuarial mediana del grupo GR fue superior al grupo PROG (25 vs. 9 meses; p Conclusion El tratamiento neoadyuvante del APBR permite seleccionar un grupo de pacientes en el que la reseccion consigue una supervivencia superior al grupo en el que se observa progresion. La reseccion pancreatica posneoadyuvancia requiere resecciones vasculares en la mayoria de los casos.

Introduction: home parenteral nutrition (NPD) is a complex technique that involves multidisciplinary follow-up. Objectives: descriptive analysis of all patients included in the NPD program. Methods: retrospective study of patients with NPD between 1985 and 2017 in our center, a tertiary university hospital. Results: we analyzed 61 patients (32 men, mean age: 51.2 years). The most common underlying pathology was neoplasia (32.8%), with short bowel syndrome (SIC) being the main indication of NPD (70.5%). Forty-five patients received partial NPD and 16 total. The tunnelled vein catheter was the most common venous access used. 20 patients suspended it for complete oral intake (19 the first 5 years), 26 were deceased (18 the first 5 years) and 15 maintain it. Neoplasia was the most frequent cause of death (46.2%) and in 15.4% liver disease was associated with NPD. The median duration of NPD was 25 months [1-394]; being in 24 patients longer than 5 years (8 dead, only 1 for oncologic cause not related to the NPD). Fifty-four per cent had catheter infections, being isolated 55.2% Staphylococcus coagulase negative, with an infection rate of 1.04 per 1000 days of catheterization. Conclusions: NPD is a useful therapeutic strategy in intestinal failure. The SIC is the most frequent indication in our case study. The underlying pathology, such as neoplasia, will determine the prognosis. Catheter infection is the more frequent complication, so it is necessary to strengthen health education and antiseptic prophylaxis.Introducción: la nutrición parenteral domiciliaria (NPD) es una técnica compleja que implica un seguimiento multidisciplinar. Objetivos: análisis descriptivo de todos los pacientes incluidos en el programa de NPD. Métodos: estudio retrospectivo de los pacientes con NPD entre 1985 y 2017 en nuestro centro, un hospital universitario terciario. Resultados: analizamos 61 pacientes (32 hombres, edad media: 51,2 años). La patología de base más frecuente fue la neoplasia (32,8%), siendo el síndrome de intestino corto (SIC) la principal indicación de NPD (70,5%). Recibieron NPD parcial 45 pacientes y total, 16. El tipo de catéter más empleado fue el venoso tunelizado. Veinte pacientes la suspendieron por ingesta oral completa (19 los primeros cinco años), 26 por exitus (18 los primeros cinco años) y 15 la mantienen. La neoplasia fue la causa de muerte más frecuente (46,2%) y en un 15,4%, la hepatopatía asociada a NPD. La duración mediana de la NPD fue de 25 meses (1-394), siendo en 24 pacientes mayor a cinco años (ocho fallecidos, solo uno de causa oncológica no relacionada con la NPD). Un 54% presentaron infecciones de catéter, aislándose Staphylococcus coagulasa negativo en el 55,2%, con una tasa de infección de 1,04 por 1,000 días de cateterización. Conclusiones: la NPD es una estrategia terapéutica útil en el fracaso intestinal. El SIC es la indicación más frecuente en nuestra casuística. La patología de base, como la neoplasia, determinará el pronóstico. La infección por catéter es la complicación más frecuente, por lo que es necesario reforzar la educación sanitaria y la profilaxis antiséptica.

Altered activity in decision-making neural circuitry may underlie the maladaptive food choices found in obesity. Here, we aimed to identify the brain regions purportedly underpinning risk-taking behavior in individuals with obesity. Twenty-three adult women with obesity and twenty-three healthy weight controls completed the Risky Gains Task during functional magnetic resonance imaging (fMRI). This task allows participants to choose between a safe option for a small, guaranteed monetary reward and risky options with larger rewards. fMRI analyses comparing losing trials to winning trials found that participants with obesity presented decreased activity in the left anterior insula in comparison to controls (p &lt, 0.05, AlphaSim corrected). Moreover, left insula activation during losses vs. wins was negatively correlated with UPPS-P questionnaire sensation seeking scores. During safe vs. risky trials following a loss, the control group exhibited increased activation in the ventromedial prefrontal cortex (vmPFC) (p &lt, 0.05, AlphaSim corrected) in comparison to the OB group. Moreover, vmPFC response in the obesity group during post-loss trials was negatively correlated with risky choices on the task overall. As a whole, our findings support that diminished tuning of the insula towards interoceptive signals may lead to a lack of input to the vmPFC when weighing the costs and benefits of risky choices.

We aimed to explore the relationship between GLP-1 receptor (GLP-1R) expression in adipose tissue (AT) and incretin secretion, glucose homeostasis and weight loss, in patients with morbid obesity and type 2 diabetes undergoing bariatric surgery. RNA was extracted from subcutaneous (SAT) and visceral (VAT) AT biopsies from 40 patients randomized to metabolic gastric bypass, sleeve gastrectomy or greater curvature plication. Biochemical parameters, fasting plasma insulin, glucagon and area under the curve (AUC) of GLP-1 following a standard meal test were determined before and 1 year after bariatric surgery. GLP-1R expression was higher in VAT than in SAT. GLP-1R expression in VAT correlated with weight (r = −0.453, p = 0.008), waist circumference (r = −0.494, p = 0.004), plasma insulin (r = −0.466, p = 0.007), and systolic blood pressure (BP) (r = −0.410, p = 0.018). At 1 year, GLP-1R expression in VAT was negatively associated with diastolic BP (r = −0.361, p = 0.039) and, following metabolic gastric bypass, with the increase of GLP-1 AUC, (R2 = 0.46, p = 0.038). Finally, GLP-1R in AT was similar independently of diabetes outcomes and was not associated with weight loss after surgery. Thus, GLP-1R expression in AT is of limited value to predict incretin response and does not play a role in metabolic outcomes after bariatric surgery.

Maladaptive emotion regulation contributes to overeating and impedes weight loss. Our study aimed to compare the voluntary downregulation of negative emotions by means of cognitive reappraisal in adult women with obesity (OB) and female healthy controls (HC) using a data-driven, multimodal magnetic resonance imaging (MRI) approach. Women with OB (n = 24) and HC (n = 25) carried out an emotion regulation task during functional MRI scanning. Seed-to-voxel resting-state connectivity patterns derived from activation peaks identified by this task were compared between groups. Diffusion tensor imaging (DTI) was used to examine white matter microstructure integrity between regions exhibiting group differences in resting-state functional connectivity. Participants in the OB group presented reduced activation in the ventromedial prefrontal (vmPFC) cortex in comparison to the HC group when downregulating negative emotions, along with heightened activation in the extrastriate visual cortex (p, Instituto de Salud Carlos III (ISCIII) (FIS PI14/00290, PI17/ 01167; PI13/01958) and co-funded by FEDER funds/European Regional Development Fund (ERDF), a way to build Europe.

There are no studies that have specifically assessed the role of intravenous lipid emulsions (ILE) enriched with fish oil in people with diabetes receiving total parenteral nutrition (TPN). The objective of this study was to assess the metabolic control (glycemic and lipid) and in-hospital complications that occurred in non-critically ill inpatients with TPN and type 2 diabetes with regard to the use of fish oil emulsions compared with other ILEs. We performed a post-hoc analysis of the Insulin in Parenteral Nutrition (INSUPAR) trial that included patients who started with TPN for any cause and that would predictably continue with TPN for at least five days. The study included 161 patients who started with TPN for any cause. There were 80 patients (49.7%) on fish oil enriched ILEs and 81 patients (50.3%) on other ILEs. We found significant decreases in triglyceride levels in the fish oil group compared to the other patients. We did not find any differences in glucose metabolic control: mean capillary glucose, glycemic variability, and insulin dose, except in the number of mild hypoglycemic events that was significantly higher in the fish oil group. We did not observe any differences in other metabolic, liver or infectious complications, in-hospital length of stay or mortality., This work was supported by Instituto de Salud Carlos III (ISCIII, co-funded by Fondo Europeo de Desarrollo Regional [FEDER], European Union [EU], Una manera de hacer Europa), Ministerio de Ciencia, Innovacion y Universidades, Gobierno de Espana (PI15/01034), and Sociedad Andaluza de Endocrinologia Diabetes y Nutrition (SAEDYN) 2016 research project.

Introduction Evidence suggests that food addiction (FA) is prevalent among individuals with obesity seeking bariatric surgery (BS), but there is no evidence about whether FA is a predictor of weight loss (WL). We aimed to analyse the prevalence of FA in patients with obesity seeking BS and to examine whether FA could predict WL following dietary intervention before surgery. Method The study included 110 patients with obesity who underwent a dietetic intervention. Assessment included endocrinological variables, a semistructured interview to rule out mental disorders, and Yale Food Addiction Scale version 2.0 (YFAS 2.0). Results In our sample, the prevalence of FA was 26.4%. Those who met YFAS 2.0 criteria showed less WL after dietetic intervention and regain weight during dietary intervention. Conclusions FA appears to be prevalent in obesity. Our findings confirmed a lower WL throughout dietary intervention before surgery in patients who fulfilled baseline criteria for FA. Future interventions should include multidisciplinary intervention to maximize WL before and after BS.

Background Individuals with obesity (OB) often report suffering from addiction-like symptoms. As in addictions, deficits in executive function domains, such as decision-making and sustained attention, are found in OB. No study to date has examined the associations between food addiction, OB, and neuropsychological performance. Method Thirty-three adult women with OB and 36 healthy weight controls completed the Yale Food Addiction Scale Version 2.0, a validated instrument used to assess food-related addictive behaviours. Additionally, participants completed computerized versions of the Iowa Gambling Task (IGT) and Conners' Continuous Performance Test, second edition (CPT-II) to examine decision-making and attentional control, respectively. Results Food addiction criteria were met in 24.2% of the participants with OB and in 2.8% of the control group. In the OB group, food addiction severity levels were negatively correlated with overall scores on the IGT. Participants with OB meeting criteria for food addiction committed more omissions and perseveration errors on the CPT-II compared with those without food addiction. Conclusions Our results point to an association between food addiction severity levels and impairments in decision-making and attentional capacity in individuals with OB. Given the heterogeneity found in OB, it stands to reason that this subset of patients with food addiction could potentially benefit from interventions targeting neuropsychological deficits.

Bariatric surgery (BS) has proven to be the most effective treatment for weight loss and for improving comorbidities in severe obesity. A comprehensive psychological assessment prior to surgery is proposed to prepare patients for a successful post-surgical outcome. Therefore, the main aim of the present study was to assess psychological and personality predictors of BS outcome. The sample comprised 139 severely obese patients who underwent BS. Assessment measures included the Eating Disorders Inventory-2, the Symptom Checklist-Revised and the Temperament and Character Inventory-Revised. Our results show that favourable BS outcome, after 2 years follow up, was associated with younger age, less depression, moderate anxiety symptoms and high cooperativeness levels. Likewise, metabolic improvements were found to be linked to younger age and certain psychopathological factors. In conclusion, our findings suggest that age, baseline body mass index, psychopathological indexes and personality traits predict successful BS outcome.

Introduction: Malnutrition is common in patients admitted to hospital and is associated with morbidity and mortality. We conducted a study to assess the prevalence of nutritional risk, risk factors associated and its consequences in a third-level hospital. Methods: This is a prospective nutritional screening study of hospitalized patients evaluated within the first 72 hours of admission, by Malnutrition Universal Screening Tool (MUST) and Short Nutritional Assessment Questionnaire (SNAQ) screening tests. The variables recorded included demographic, anthropometric, hospitalization and clinical data. Results: Out of 409 patients, 12.7% and 15.3% were nutritionally at risk according to MUST and SNAQ, respectively, with the highest prevalence in critical care units (33.3%; 25.5%), amongst oncologic patients (17.5%; 28.4%) and those with higher Charlson comorbidity indices (CCI). Length of stay (LOS) was longer in patients at severe malnutrition risk (15.4 vs 9.9 days for MUST; 13.3 vs 9.9 days for SNAQ). Mortality was higher in those with high malnutrition risk (66.7% vs 10.9% for MUST; 50.0% vs 14.2% for SNAQ). Multivariate analysis showed that malnutrition was associated with CCI and mortality. Risk factors associated with LOS were admission as emergencies for both MUST and SNAQ tests. Conclusions: The prevalence of malnutrition is high in patients on admission to a third-level hospital, with a higher prevalence in critical care units, amongst oncologic patients and those with a higher CCI. Malnutrition is associated with longer LOS and higher mortality. The systematic clinical use of screening tools enables to detect patients at risk of malnutrition and take appropriate action. Introducción: la desnutrición es común en los pacientes ingresados en el hospital y se asocia a morbi/mortalidad. El objetivo de este estudio es evaluar la prevalencia de riesgo nutricional, factores de riesgo asociados y sus consecuencias en un hospital de tercer nivel. Métodos: estudio prospectivo de cribado nutricional de pacientes hospitalizados evaluados dentro de las primeras 72 horas de ingreso, mediante las herramientas Malnutrition Universal Screening Tool (MUST) y Short Nutritional Assessment Questionnaire (SNAQ). Las variables registradas incluyen datos demográficos, antropométricos, de hospitalización y clínicos. Resultados: de los 409 pacientes entrevistados, 12,7% y 15,3% presentaban riesgo nutricional según MUST y SNAQ, respectivamente, con una mayor prevalencia en la Unidad de Cuidados Intensivos (UCI) (33,3%; 25,5%), pacientes oncológicos (17,5%; 28,4%) y aquellos con mayor índice de comorbilidad de Charlson (ICC). La estancia hospitalaria fue mayor en pacientes en riesgo de desnutrición severa (15,4 vs. 9,9 días para MUST; 13,3 vs. 9,9 días para SNAQ), así como la mortalidad (66,7% vs. 10,9% para MUST; 50,0% vs. 14,2% para SNAQ). El análisis multivariante mostró una asociación entre desnutrición e ICC y mortalidad. Los factores de riesgo asociados con estancia hospitalaria fueron ingreso por urgencias para ambos tests. Conclusiones: la prevalencia de desnutrición en pacientes al ingreso a un hospital de tercer nivel es alta, siendo mayor en las UCI, entre pacientes oncológicos y con mayor ICC. La desnutrición se asocia con mayor estancia hospitalaria y mayor mortalidad. El uso clínico sistemático de herramientas de detección puede ayudar a identificar pacientes en riesgo de desnutrición y tomar las medidas apropiadas.

Introduction A borderline resectable group (APBR) has recently been defined in adenocarcinoma of the pancreas. The objective of the study is to evaluate the results in the surgical treatment after neoadjuvancy of the APBR. Method Between 2010 and 2014, we included patients with APBR in a neoadjuvant and surgery protocol, staged by multidetector computed tomography (MDCT). Treatment with chemotherapy was based on gemcitabine and oxaliplatin. Subsequently, MDCT was performed to rule out progression, and 5-FU infusion and concomitant radiotherapy were given. MDCT and resection were performed in absence of progression. A descriptive statistical study was performed, dividing the series into: surgery group (GR group) and progression group (PROG group). Results We indicated neoadjuvant treatment to 22 patients, 11 of them were operated, 9 pancreatoduodenectomies, and 2 distal pancreatectomies. Of the 11 patients, 7 required some type of vascular resection; 5 venous resections, one arterial and one both. No postoperative mortality was recorded, 7 (63%) had any complications, and 4 were reoperated. The median postoperative stay was 17 (7–75) days. The pathological study showed complete response (ypT0) in 27%, and free microscopic margins (R0) in 63%. At study clossure, all patients had died, with a median actuarial survival of 13 months (9.6–16.3). The median actuarial survival of the GR group was higher than the PROG group (25 vs 9 months; P Conclusion The neoadjuvant treatment of APBR allows us to select a group of patients in whom resection achieves a longer survival to the group in which progression is observed. Post-adjuvant pancreatic resection requires vascular resection in most cases.

Background The purpose of this study was to evaluate the efficacy and safety of Endobarrier® in grade 1 obese T2DM patients with poor metabolic control and the role of gastro-intestinal hormone changes on the metabolic outcomes. Methods Twenty-one patients aged 54.1 ± 9.5 years, diabetes duration 14.8 ± 8.5 years, BMI 33.4 ± 1.9 kg/m2, and HbA1c 9.1 ± 1.3 %, under insulin therapy, were implanted with Endobarrier®. Fasting concentrations of PYY, ghrelin and glucagon, and AUC for GLP-1 after a standard meal test were determined prior to and at months 1 and 12 after implantation. Results Patients lost 14.9 ± 5.7 % of their total body weight. HbA1c decreased 1.3 % in the first month, but at the end of the study, the reduction was 0.6 %. HbA1c ≤ 7 % was achieved in 26.3 % of patients. No differences in GLP-1 AUC values were found before and after implant. Fasting plasma ghrelin and PYY concentrations increased from month 1 to 12. Conversely, fasting plasma glucagon concentrations decreased at month 1 and increased thereafter. Weight (β 0.152) and HbA1c decrease at month 1 (β 0.176) were the only variables predictive of HbA1c values at 12 months (adjusted R 2 for the model 0.693, p = 0.001). Minor adverse events occurred in 14 % of patients and major events in 9.5 %. Conclusions Endobarrier® in T2DM patients with grade I obesity and poor metabolic control is associated with significant weight decrease and moderate reduction in HbA1c at month 12. Our data do not support a role for GLP-1 in the metabolic improvement in this subset of patients.

Objetivo: Comunicar dos casos de metástasis tardías de carcinoma renal de células claras. Métodos: Dos pacientes, hombre y mujer, con historia de nefrectomía previa hacía 17 y 16 años respectivamente, presentaron nuevos tumores en tiroides y páncreas, que se extirparon. Resultados: La histopatología de ambas lesiones correspondió a tumores de células claras y el estudio inmunohistoquímico fue compatible con metástasis de carcinoma renal de células claras. Conclusiones: 1º) Ante nodulos en tiroides o páncreas, en pacientes con historia previa de cualquier tipo de carcinoma, se debe considerar la posibilidad de una metástasis. 2º) Los pacientes con carcinoma renal de células claras y nefrectomía (resección), deben tener un seguimiento de por vida, con una actitud de alerta a la aparición de nódulos en tiroides o en páncreas. 3º) En presencia de un tumor de células claras en tiroides o en páncreas, se debe incluir la posibilidad de un carcinoma renal metastático en el diagnóstico diferencial. 4º) El tratamiento de elección es la resección quirúrgica.
