RESUMO
This paper presents baseline results from the NutriEcoMuscle study, a multicenter observational study conducted in Spain which focused on changes in nutritional status, body composition, and functionality in post-intensive care unit (ICU) COVID-19 patients following a nutritional intervention. Assessments at hospital discharge included Subjective Global Assessment (SGA), Global Leadership Initiative on Malnutrition (GLIM) criteria, the Barthel index, handgrip strength (HGS) and the Timed Up-and-Go test, bioelectrical impedance analysis (BIA), and nutritional ultrasound (US). The study involved 96 patients (71.9% male, mean age 58.8 years, mean BMI 28.8 kg/m2, 36.5% obese). All patients were malnourished at discharge according to GLIM and SGA. Functional status declined from admission up to hospital discharge. A total of 33.3% of patients had a low fat-free mass index (FFMI) and 29.5% had a low phase angle (PhA). Myosteatosis was observed in 83.7% of the population. There was a positive correlation between rectus femoris cross-sectional area, PhA, FFMI, and HGS. In conclusion, post-critically ill COVID-19 patients commonly suffer from malnutrition and reduced muscle mass, causing a loss of independence at hospital discharge. BIA and US could be valuable tools for assessing body composition in these patients. The NutriEcoMuscle study highlights the need for a thorough nutritional and morphofunctional status assessment of post-ICU patients.

Background and aims: The diagnosis of malnutrition in post-critical COVID-19 patients is challenging as a result of the high prevalence of obesity, as well as the variability and previously reported inconsistencies across currently available assessment methods. Bioelectrical impedance vector analysis (BIVA) with phase angle (PhA) and nutritional ultrasound (NU®) are emerging techniques that have been proven successful in assessing body composition with high precision in previous studies. Our study aims to determine the performance and usefulness of PhA and rectus femoris cross-sectional area (RF-CSA) measurements in assessing body composition as part of the full routine morphofunctional assessment used in the clinical setting, as well as their capacity to predict severe malnutrition and to assess complications and aggressive therapy requirements during recent intensive care unit (ICU) admission, in a cohort of post-critically ill COVID-19 outpatients. Methods: This prospective observational study included 75 post-critical outpatients who recovered from severe COVID-19 pneumonia after requiring ICU admission. Correlations between all the morphofunctional parameters, complications, and aggressive therapy requirements during admission were analyzed. Multivariate logistic regression analysis and ROC curves were provided to determine the performance of NU® and PhA to predict severe malnutrition. Differences in complications and aggressive therapy requirements using the cutoff points obtained were analyzed. Results: In total, 54.7% of patients were classified by Subjective Global Assessment (SGA) as SGA-B and 45.3% as SGA-C, while 78.7% met the Global Leadership Initiative of Malnutrition (GLIM) criteria. PhA correlates positively with body cell mass/height (BCM/h) (r = 0.74), skeletal muscle index (SMI) (r = 0.29), RF-CSA (r = 0.22), RF-Y axis (r = 0.42), and handgrip strength (HGS) assessed using dynamometry (r = 0.42) and the Barthel scale (r = 0.29) and negatively with ICU stay (r = -0.48), total hospital stay (r = -0.57), need for invasive mechanical ventilation (IMV) (r = -0.39), days of IMV (r = -0.41), need for tracheostomy (r = -0.51), and number of prone maneuvers (r = -0.20). RF-CSA correlates positively with BCM/h (r = 0.41), SMI (r = 0.58), RF-Y axis (r = 0.69), and HGS assessed using dynamometry (r = 0.50) and the Barthel scale (r = 0.15) and negatively with total hospital stay (r = -0.22) and need for IMV (r = -0.28). Cutoff points of PhA < 5.4° and standardized phase angle (SPhA) < -0.79 showed good capacity to predict severe malnutrition according to SGA and revealed differences in ICU stay, total hospital stay, number of prone maneuvers, need for IMV, and need for rehabilitation, with statistical significance (p < 0.05). An RF-CSA/h < 2.52 cm2/m (for men) and <2.21 cm2/m (for women) also showed good performance in predicting severe malnutrition and revealed differences with statistical significance (p < 0.05) in ICU stay and total hospital stay. Conclusion: More than 75% of the post-critical COVID-19 survivors had malnutrition, and approximately half were obese. PhA, SPhA, RF-CSA, and RF-CSA/h, when applied to the assessment of body composition in post-critical COVID-19 patients, showed moderate-to-high correlation with other morphofunctional parameters and good performance to predict severe malnutrition and to assess complications and aggressive therapy requirements during ICU admission. Besides being readily available methods, BIVA and NU® can help improve the morphofunctional assessment of malnutrition in post-critical COVID-19 survivors; however, more studies are needed to assess the performance of these methods in other populations.
RESUMO
Introduction: Objectives: an expert report is presented on the situation of loss of muscle mass in people with type 2 diabetes mellitus (T2DM), with a proposal of what the clinical approach to this comorbidity should be, based on the evidence from the literature and clinical experience. Method: a qualitative expert opinion study was carried out using the nominal approach. A literature search on diabetes and muscle was made and submitted to a multidisciplinary group of 7 experts who through a face-to-face meeting discussed different aspects of the role of muscle mass in T2DM. Results: muscle mass must be taken into account in the clinical context of patients with T2DM. It has an enormous impact on patient function and quality of life, and is as important as adequate metabolic control of T2DM. Conclusions: in addition to drug therapy and diet adjustments, aerobic and strength activities are essential for maintaining muscle mass and function in diabetic patients. In concrete situations, artificial oral supplementation specific for muscle care could improve the situation of malnutrition and low muscle mass. Measures such as the walking speed test, chair test, or the SARC-F questionnaire, together with the Barthel index, constitute a first step to diagnose relevant impairment requiring intervention in patients with T2DM. This document seeks to answer some questions about the importance, assessment, and control of muscle mass in T2DM.
Introducción: Objetivos: informe de expertos para valorar la realidad de la pérdida de masa muscular en las personas con diabetes mellitus 2 (DM2) y proponer, en base a la evidencia de la bibliografía y la experiencia clínica, cómo debería ser el abordaje clínico de esta comorbilidad. Método: estudio cualitativo de opinión de expertos mediante metodología nominal. Se realizó una búsqueda bibliográfica sobre diabetes y músculos que se remitió a un grupo multidisciplinar de 7 expertos que, en reunión presencial, discutieron sobre diversos aspectos del papel de la masa muscular en la DM2. Resultados: la masa muscular debe tenerse en cuenta dentro del cuadro clínico del paciente con DM2. Repercute enormemente sobre la funcionalidad y la calidad de vida del paciente y es tan importante como el adecuado control metabólico de la DM2. Conclusión: además de la terapia farmacológica y la dieta adaptada, es imprescindible un patrón de actividad física aeróbica y de fuerza para el mantenimiento de la masa y la función muscular en el paciente diabético. En situaciones particulares, una suplementación oral artificial específica para el cuidado del músculo podría mejorar la situación de desnutrición y baja masa muscular. Medidas como el test de la velocidad de marcha, el test de la silla o el cuestionario SARC-F, junto a un índice de Barthel, son un primer paso para diagnosticar un deterioro relevante sobre el que actuar en el paciente DM2. Este documento pretende resolver algunos interrogantes sobre la importancia, la valoración y el control de la masa muscular en la DM2.

INTRODUCTION: In order to develop evidence-based recommendations and expert consensus for the nutritional management of patients with short bowel syndrome (SBS), we conducted a systematic literature search using the PRISMA methodology plus a critical appraisal following the GRADE scale procedures. Pharmacological treatment with antisecretory drugs, antidiarrheal drugs, and somatostatin contributes to reducing intestinal losses. Nutritional support is based on parenteral nutrition; however, oral intake and/or enteral nutrition should be introduced as soon as possible. In the chronic phase, the diet should have as few restrictions as possible, and be adapted to the SBS type. Home parenteral nutrition (HPN) should be individualized. Single-lumen catheters are recommended and taurolidine should be used for locking the catheter. The HPN's lipid content must be greater than 1 g/kg per week but not exceed 1 g/kg per day, and omega-6 fatty acids (ω6 FAs) should be reduced. Trace element vials with low doses of manganese should be used. Patients with chronic SBS who require long-term HPN/fluid therapy despite optimized treatment should be considered for teduglutide treatment. All patients require a multidisciplinary approach and specialized follow-up. These recommendations and suggestions regarding nutritional management in SBS patients have direct clinical applicability.
INTRODUCCIÓN: Con el fin de desarrollar recomendaciones basadas en la evidencia y el consenso de expertos para el manejo nutricional de los pacientes con síndrome de intestino corto (SIC), realizamos una búsqueda bibliográfica sistemática utilizando la metodología PRISMA junto a una valoración crítica siguiendo los procedimientos de la escala GRADE. El tratamiento farmacológico con fármacos antisecretores, antidiarreicos y somatostatina contribuye a reducir las pérdidas intestinales. El apoyo nutricional se basa en la nutrición parenteral; sin embargo, la ingesta oral y/o la nutrición enteral deben introducirse lo antes posible. En la fase crónica, la dieta debe tener las menores restricciones posibles y adaptarse al tipo de SIC. La nutrición parenteral domiciliaria (NPD) debe individualizarse. Se recomiendan catéteres de un solo lumen y se debe utilizar taurolidina para bloquear el catéter. El contenido de lípidos de la HPN debe ser superior a 1 g/kg por semana, pero no debe exceder 1 g/kg por día, y debe reducirse el ácido graso omega-6 (AG ω6). Deben utilizarse viales de oligoelementos con dosis bajas de manganeso. Los pacientes con SIC crónico que requieren NPD/fluidoterapia a largo plazo a pesar del tratamiento optimizado deben considerarse para el tratamiento con teduglutida. Todos los pacientes requieren un abordaje multidisciplinar y un seguimiento especializado. Estas recomendaciones y sugerencias con respecto al manejo nutricional de los pacientes con SIC tienen aplicabilidad clínica directa.

Options for treatment of obesity include dietary approaches and bariatric surgery. Previous studies have shown that weight loss interventions have an impact on gut microbiota. However, a pattern of gut microbiota changes associated with weight loss independently of the type of intervention has not been described yet. This study includes 61 individuals who followed different weight loss strategies in three different trials: 21 followed a hypocaloric Mediterranean diet (MedDiet), 18 followed a very-low-calorie ketogenic diet (VLCKD) and 22 patients underwent sleeve gastrectomy bariatric surgery (BS). Gut microbiota profile was assessed by next-generation sequencing. A common taxon that had significantly changed within the three weight loss interventions could not be find. At the family level, Clostiridiaceae significantly increased its abundance with MedDiet and VLCKD, whilst Porphyromonadacean and Rikenellaceae significantly increased with VLCKD and BS. At genus level, in VLCKD and BS, Parabacteroides and Alistipes significantly increased their abundance whilst Lactobacillus decreased. At the species level, BS and VLCKD produced an increase in Parabacteroidesdistasonis and a decrease in Eubactieriumventriosum and Lactobacillusrogosae, whilst Orodibactersplanchnicus increased its abundance after the BS and MedDiet. Predicted metagenome analysis suggested that most of the changes after VLCKD were focused on pathways related to biosynthesis and degradation/utilization/assimilation, while BS seems to decrease most of the biosynthesis pathways. MedDiet was enriched in several pathways related to fermentation to short-chain fatty acids. Our results show that weight loss is not associated with a specific pattern of gut microbiota changes independently of the strategy used. Indeed, gut microbiota changes according to type of weight loss intervention.
RESUMO
In order to develop evidence-based recommendations and expert consensus for nutrition management of patients undergoing bariatric surgery and postoperative follow-up, we conducted a systematic literature search using PRISMA methodology plus critical appraisal following the SIGN and AGREE-II procedures. The results were discussed among all members of the GARIN group, and all members answered a Likert scale questionnaire to assess the degree of support for every recommendation. Patients undergoing bariatric surgery should be screened preoperatively for some micronutrient deficiencies and treated accordingly. A VLCD (Very Low-Calorie Diet) should be used for 4-8 weeks prior to surgery. Postoperatively, a liquid diet should be maintained for a month, followed by a semi-solid diet also for one month. Protein requirements (1-1.5 g/kg) should be estimated using adjusted weight. Systematic use of specific multivitamin supplements is encouraged. Calcium citrate and vitamin D supplements should be used at higher doses than are currently recommended. The use of proton-pump inhibitors should be individualised, and vitamin B12 and iron should be supplemented in case of deficit. All patients, especially pregnant women, teenagers, and elderly patients require a multidisciplinary approach and specialised follow-up. These recommendations and suggestions regarding nutrition management when undergoing bariatric surgery and postoperative follow-up have direct clinical applicability.

Objective: Treatment of hyperglycemia with insulin is associated with increased risk of hypoglycemia in type 2 diabetes mellitus (T2DM) patients receiving total parenteral nutrition (TPN). The aim of this study was to determine the predictors of hypoglycemia in hospitalized T2DM patients receiving TPN. Methods: Post hoc analysis of the INSUPAR study, which is a prospective, open-label, multicenter clinical trial of adult inpatients with T2DM in a noncritical setting with indication for TPN. Results: The study included 161 patients; 31 patients (19.3%) had hypoglycemic events, but none of them was severe. In univariate analysis, hypoglycemia was significantly associated with the presence of diabetes with end-organ damage, duration of diabetes, use of insulin prior to admission, glycemic variability (GV), belonging to the glargine insulin group in the INSUPAR trial, mean daily grams of lipids in TPN, mean insulin per 10 grams of carbohydrates, duration of TPN, and increase in urea during TPN. Multiple logistic regression analysis showed that the presence of diabetes with end-organ damage, GV, use of glargine insulin, and TPN duration were risk factors for hypoglycemia. Conclusion: The presence of T2DM with end-organ damage complications, longer TPN duration, belonging to the glargine insulin group, and greater GV are factors associated with the risk of hypoglycemia in diabetic noncritically ill inpatients with parenteral nutrition. Abbreviations: ADA = American Diabetes Association; BMI = body mass index; CV% = coefficient of variation; DM = diabetes mellitus; GI = glargine insulin; GV = glycemic variability; ICU = intensive care unit; RI = regular insulin; T2DM = type 2 diabetes mellitus; TPN = total parenteral nutrition.

BACKGROUND: Diabetes and older age are associated with an increased risk of malnutrition and mortality. Recently, the Global Leadership Initiative on Malnutrition (GLIM) provided a 2-step approach for the malnutrition diagnosis. In this study, we aimed to determine whether GLIM nutrition status at admission was associated with long-term survival in elderly patients with type 2 diabetes mellitus (T2DM). Additionally, we aimed to identify which GLIM criteria were more able to become prognostic indicators of early or late death. METHODS: Our study included a convenience sample of 159 patients with T2DM older than 65 years and admitted to the internal medicine wards of different Spanish hospitals: the VIDA-survival cohort. Nutrition status was retrospectively assessed with the new GLIM criteria. The main outcome was long-term mortality in the cohort during an 8-year follow-up. Bivariate tables summarized the variables of interest. Kaplan-Meier survival curves and adjusted Cox regressions were also performed. RESULTS: According to the GLIM criteria, we observed that the 35.8% and 16.3% of the VIDA-survival cohort were categorized as having moderate and severe malnutrition, respectively. Severe malnutrition was associated with increased mortality (hazard ratio [HR] = 2.09; 95% CI, 1.29-3.38), compared with nonmalnourished participants. Moderate malnutrition had a neutral effect on all-cause mortality (HR = 1.30; 95% CI, 0.88-1.92). Low plasma albumin levels, a surrogate marker of inflammation, were strongly associated with early mortality. CONCLUSION: Our study provides evidence that severe malnutrition according to GLIM criteria is associated with increased long-term all-cause mortality among elderly individuals with T2DM.

BACKGROUND: There is no established insulin regimen in T2DM patients receiving parenteral nutrition. AIMS: To compare the effectiveness (metabolic control) and safety of two insulin regimens in patients with diabetes receiving TPN. DESIGN: Prospective, open-label, multicenter, clinical trial on adult inpatients with type 2 diabetes on a non-critical setting with indication for TPN. Patients were randomized on one of these two regimens: 100% of RI on TPN or 50% of Regular insulin added to TPN bag and 50% subcutaneous GI. Data were analyzed according to intention-to-treat principle. RESULTS: 81 patients were on RI and 80 on GI. No differences were observed in neither average total daily dose of insulin, programmed or correction, nor in capillary mean blood glucose during TPN infusion (165.3 ± 35.4 in RI vs 172.5 ± 43.6 mg/dL in GI; p = 0.25). Mean capillary glucose was significantly lower in the GI group within two days after TPN interruption (160.3 ± 45.1 in RI vs 141.7 ± 43.8 mg/dL in GI; p = 0.024). The percentage of capillary glucose above 180 mg/dL was similar in both groups. The rate of capillary glucose ≤70 mg/dL, the number of hypoglycemic episodes per 100 days of TPN, and the percentage of patients with non-severe hypoglycemia were significantly higher on GI group. No severe hypoglycemia was detected. No differences were observed in length of stay, infectious complications, or hospital mortality. CONCLUSION: Effectiveness of both regimens was similar. GI group achieved better metabolic control after TPN interruption but non-severe hypoglycemia rate was higher in the GI group. CLINICAL TRIAL REGISTRY: This trial is registered at clinicaltrials.gov as NCT02706119.

Background: In patients with nutritional risk, the European Society for Clinical Nutrition and Metabolism (ESPEN) recommends nutritional supplements during cancer treatment to prevent weight loss. Objectives: Our goal is to determine the acceptability, compliance and tolerance of a hyperproteic, high-calorie, omega-3 enriched supplement in cancer patients. Methods: Unicentric, prospective observational study in cancer patients with hyperproteic, high-calorie, rich in omega 3 and low volume nutritional supplement. Thirty patients with malnutrition or risk of malnutrition were included. Supplementation lasted six days. Compliance (packaging used), acceptability (Madrid scale), anthropometric variables and gastrointestinal adverse events (AEs) were evaluated. Results: Seventy per cent were men, with an average age of 60 years (range 32-79), with lung (43.3%), ENT (26.7%) and breast neoplasms (13.3%), stage III-IV (56.7%), and treated with radiotherapy (93.3%), chemotherapy (60%) and surgery (16.7%). The product was accepted by all patients. A compliance rate of 100% was observed. Gastrointestinal AE (grade II) related to the supplement was observed in two patients (6.7%). Both subjects had previous gastrointestinal diseases. The median weight, body mass index (BMI) and protein intake increased during supplementation (0.2 kg, 0.1 kg/m2 and 6.2 g). No differences were observed regarding calorie, fat and carbohydrates intake. Conclusion: The high acceptance and compliance with the specific nutritional supplement was associated with an improved nutritional status for cancer patients, and reversed the weight loss without severe gastrointestinal problems, or producing intake displacement.
Introducción: en pacientes con riesgo nutricional, la Sociedad Europea de Clínica y Metabolismo (ESPEN) y Parenteral recomienda suplementos nutricionales durante el tratamiento oncológico para prevenir la pérdida de peso involuntaria. Objetivos: nuestro objetivo es conocer el cumplimiento, la aceptabilidad y la tolerancia de un suplemento hiperproteico, hipercalórico, rico en omega 3 en pacientes oncológicos. Métodos: estudio unicéntrico, observacional y prospectivo en pacientes oncológicos con un suplemento nutricional hiperproteico, hipercalórico, rico en omega 3 y de bajo volumen. Fueron incluidos 30 pacientes con desnutrición o en riesgo de desnutrición. La suplementación duró seis días. Se evaluaron el cumplimiento (envases utilizado), la aceptabilidad (escala Madrid), las variables antropométricas y los acontecimientos adversos (AA) gastrointestinales. Resultados: el 70% fueron hombres, con una edad media de 60 años (rango: 32 a 79) y con neoplasias de pulmón (43,3%), ORL (26,7%) y mama (13,3%), en estadio III-IV (56,7%), tratados con radioterapia (93,3%), quimioterapia (60%) y cirugía (16,7%). El producto fue aceptado por todos los pacientes. Se observó un cumplimiento del 100%. En dos pacientes (6,7%) se observaron AA gastrointestinales (grado II) relacionados con el suplemento; ambos sujetos presentaban patologías gastrointestinales previas. La mediana del peso, índice de masa corporal (IMC) y proteínas ingeridas aumentó durante la suplementación (0,2 kg, 0,1 kg/m2 y 6,2 g). No se observaron diferencias respecto a la ingesta de calorías, lípidos y carbohidratos. Conclusión: la elevada aceptación y cumplimiento del suplemento nutricional específico se asoció con la mejora nutricional de los pacientes oncológicos, pues revirtió la pérdida de peso, sin presentar problemas gastrointestinales severos ni producir desplazamiento de la ingesta.

Introduction: Malnutrition is a problem of high significance in hospitalized patients and it has an impact in patient stay and risk of infections. Diabetic patients represent an important percentage of hospitalized population. VIDA study aims to determine the prevalence of malnutrition in elderly diabetic patients admitted to Spanish hospitals. Aim: The aim of this study is to describe the population of VIDA study including biochemical and anthropometric parameters on admission. Methods: Cross sectional, multicentre study of 1098 diabetic patients above 65 years of age. 35 medical centers were included. Results: Mean age was 78 SD 7.1 years. The most common diagnosis at admission was respiratory tract infection. The duration of diabetes disease was above ten years in 51.2% and 33.09% was under insulin treatment. At admission, 21.22% was malnourished and 39.07% was at risk of malnutrition. The prevalence of malnutrition was higher in women (p < 0.0002). Discussion: VIDA study is the first Spanish multicentre study describing nutritional status of a large sample of elderly inpatients with diabetes mellitus. 21.22% of the 1,098 patients were malnourished. This result depends on age and sex, and can increase mortality rate.
Introducción: la malnutrición es un problema de primer orden en el paciente hospitalizado que prolonga la estancia hospitalaria y la tasa de infecciones. El paciente diabético representa un porcentaje importante de la población hospitalizada. El estudio VIDA tiene como objetivo analizar el estado nutricional de pacientes ancianos con diabetes hospitalizados en España. Objetivo: describir la población del estudio VIDA, incluyendo datos del perfil bioquímico y antropométrico en el momento del ingreso. Métodos: estudio multicéntrico, transversal, observacional llevado a cabo en 1098 pacientes mayores de 65 años. Se incluyeron 35 hospitales españoles. Resultados: la edad media de los pacientes ingresados fue 78 ± 7,1 años. El motivo de ingreso más frecuente fueron las infecciones respiratorias (32,4%). El 51,2% estaban diagnosticados de diabetes desde hacía más de 10 años. Un 33,09% recibía tratamiento con insulina. Un 39,07% presentaba riesgo de malnutrición y un 21,22% estaba mal nutrido en el momento del ingreso. Se encontró mayor prevalencia de malnutrición en el grupo de mujeres (p < 0,0002). Conclusiones: el estudio VIDA es el primero que analiza el estado nutricional de una cohorte de pacientes ancianos diabéticos en España. Enlos resultados de este proyecto se concluye que un 21,2% de la muestra presenta malnutrición. Esta condición es edad y sexo dependiente, y puede empeorar la tasa de mortalidad.

BACKGROUND & AIMS: The European Society for Clinical Nutrition and Metabolism (ESPEN) recently provided new diagnosis criteria of malnutrition and called to confirm those criteria in specific populations. The aims of our study were 1) to determine the prevalence of malnutrition according to the new ESPEN definition in elder hospitalized diabetic patients, and 2) to evaluate whether this new diagnosis of malnutrition predicted clinical outcomes in these patients. METHODS: 1014 hospitalized diabetic patients (≥65 years) from 35 hospitals in Spain were screened for being at risk of malnutrition using the short version of the Mini Nutritional Assessment. Subsequently, at risk individuals were considered malnourished if they met at least one of the two options: 1) body mass index (BMI) < 18.5 kg/m2, or 2) unintentional weight loss >5% of their body weight with reduced BMI (<20 kg/m2 in subjects younger than 70 years or <22 kg/m2 in subjects older than 70 years). RESULTS: The new ESPEN definition, with MNA-SF as initial screening, identified 68 malnourished geriatric individuals with diabetes (6.73% of the cohort). Additionally, malnutrition lengthened the hospital stay, increased 2.7 times the odds of dying in hospital, and decreased to one third the odds of being discharged home. CONCLUSIONS: Our study confirms that the new ESPEN definition for the diagnosis of malnutrition is a reliable tool that is capable of predicting clinical outcomes in a large population of elder hospitalized individuals with diabetes.

Animal studies have revealed the association between stearoyl-CoA desaturase 1 (SCD1) and obesity and insulin resistance. However, only a few studies have been undertaken in humans. We studied SCD1 in visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) from morbidly obese patients and their association with insulin resistance, sterol regulatory element binding protein-1 (SREBP-1) and ATPase p97, proteins involved in SCD1 synthesis and degradation. The insulin resistance was calculated in 40 morbidly obese patients and 11 overweight controls. Measurements were made of VAT and SAT SCD1, SREBP-1 and ATPase p97 mRNA expression and protein levels. VAT and SAT SCD1 mRNA expression levels in the morbidly obese patients were significantly lower than in the controls (P = 0.006), whereas SCD1 protein levels were significantly higher (P < 0.001). In the morbidly obese patients, the VAT SCD1 protein levels were decreased in patients with higher insulin resistance (P = 0.007). However, SAT SCD1 protein levels were increased in morbidly obese patients with higher insulin resistance (P < 0.05). Multiple linear regressions in the morbidly obese patients showed that the variable associated with the SCD1 protein levels in VAT was insulin resistance, and the variables associated with SCD1 protein levels in SAT were body mass index (BMI) and ATPase p97. In conclusion, these data suggest that the regulation of SCD1 is altered in individuals with morbid obesity and that the SCD1 protein has a different regulation in the two adipose tissues, as well as being closely linked to the degree of insulin resistance.

Peroxisome proliferator-activated receptor-gamma (PPARgamma) may play a protective role in the regulation of vascular function, partly mediated by its effects on superoxide dismutase (SOD). The aim of this study was to determine the association between PPARgamma expression in peripheral blood mononuclear cells (PBMCs) and SOD activity in morbidly obese persons with varying degrees of insulin resistance (IR). We studied in 10 morbidly obese persons (five with no IR and five with high IR) the effect of a high-fat meal on the plasma activity of various antioxidant enzymes and the mRNA expression of PPARgamma in PBMC. The high-fat meal resulted in a significant decrease in plasma SOD activity, glutathione reductase (GSH-Rd) activity, and mRNA expression of PPARgamma only in the group of morbidly obese persons with high IR. PPARgamma expression after the high-fat meal correlated with the IR levels (r = -0.803, P = 0.009) and the plasma SOD activity (r = 0.903, P = 0.001). Likewise, the reduction in PPARgamma expression correlated with the increase in free fatty acids (FFA) (r = 0.733, P = 0.016). In conclusion, the decreased expression of PPARgamma in PBMC in morbidly obese persons after a high-fat meal was associated with the state of IR, the plasma SOD activity, and the changes in the concentration of FFA.

BACKGROUND: The physiological role of apelin in obesity and diabetes remains unclear. Although apelin has been studied in persons with different conditions, no studies have yet examined the joint influence of obesity and diabetes on apelin levels. We measured the changes in apelin levels in morbidly obese subjects, with and without diabetes, and in the inverse situation of improvement in carbohydrate metabolism as a result of bariatric surgery. METHODS: The study was undertaken in 54 morbidly obese persons, 16 of whom had type 2 diabetes mellitus, before and 7 months after undergoing bariatric surgery, and in 12 healthy, nonobese persons. Measurements were made of apelin levels and insulin sensitivity by an intravenous glucose tolerance test. RESULTS: The apelin levels in the morbidly obese patients prior to surgery were significantly higher than those of the controls only when the morbidly obese subjects were diabetic (P < 0.005). Apelin levels correlated significantly in the morbidly obese patients with serum triglycerides (r = 0.292, P = 0.032) and glucose (r = 0.337, P = 0.039). Bariatric surgery resulted in a significant decrease in apelin levels only in the morbidly obese subjects with impaired fasting glucose or diabetes. The change in apelin levels correlated significantly in the morbidly obese patients with the changes in serum glucose (r = 0.338, P = 0.038) and insulin sensitivity (r = -0.417, P = 0.043). CONCLUSIONS: This study demonstrates that obesity is not the main determinant of the rise in apelin levels. The association between apelin levels and glucose concentrations and insulin sensitivity provides evidence that apelin may play a role in the pathogenesis of diabetes.

Recent studies suggest that measuring the free-fatty acids (FFA) during an intravenous glucose tolerance test (IVGTT) may provide information about the metabolic associations between serum FFA and carbohydrate and insulin metabolism. We evaluated the FFA profile during an IVGTT and determined whether this test changes the composition and concentration of FFA. An IVGTT was given to 38 severely obese persons before and 7 months after undergoing bariatric surgery and also to 12 healthy, nonobese persons. The concentration and composition of the FFA were studied at different times during the test. The concentration of FFA fell significantly faster during the IVGTT in the controls and in the severely obese persons with normal-fasting glucose (NFG) than in the severely obese persons with impaired-fasting glucose (IFG) or type 2 diabetes mellitus (T2DM) (P < 0.05). Significant differences were found in the time to minimum serum concentrations of FFA (control = NFG < IFG < T2DM) (P < 0.001). These variables improved after bariatric surgery in the three groups. The percentage of monounsaturated and n-6 polyunsaturated FFA in the control subjects and in the obese persons, both before and after surgery, decreased significantly during the IVGTT. In conclusion, during an IVGTT, severely obese persons with IFG or T2DM experienced a lower fall in the FFA than the severely obese persons with NFG and the controls, becoming normal after bariatric surgery.

The postprandial state seems to have a direct influence on oxidative status and insulin resistance. We determined the effect of an increase in plasma triglycerides after a high-fat meal on oxidative stress in severely obese patients with differing degrees of insulin resistance. The study was undertaken in 60 severely obese persons who received a 60-g fat overload with a commercial preparation. Measurements were made of insulin resistance, the plasma activity of various antioxidant enzymes, the total antioxidant capacity (TAC) and the plasma concentration of thiobarbituric acid reactive substances (TBARS). The patients with greater insulin resistance had a lower plasma superoxide dismutase (SOD) activity (P < 0.05) and a greater glutathione peroxidase (GSH-Px) activity (P < 0.05). The high-fat meal caused a significant reduction in SOD activity and an increase in the plasma concentration of TBARS in all the patients. Only the patients with lower insulin resistance experienced a significant increase in plasma catalase activity (2.22 +/- 1.02 vs. 2.93 +/- 1.22 nmol/min/ml, P < 0.01), remaining stable in the patients with greater insulin resistance. These latter patients had a reduction in plasma TAC (6.92 +/- 1.93 vs. 6.29 +/- 1.80 mmol/l, P < 0.01). In conclusion, our results show a close association between the degree of insulin resistance and markers of oxidative stress, both before and after a high-fat meal. The postprandial state causes an important increase in oxidative stress, especially in severely obese persons with greater insulin resistance. However, we are unable to determine from this study whether there is first an increase in oxidative stress or in insulin resistance.

OBJECTIVE: Antioxidized LDL (anti-oxLDL) antibodies have recently been suggested to be protective against the development of diabetes. We measured the changes in anti-oxLDL antibody levels in the inverse situation of improvement in carbohydrate metabolism. RESEARCH DESIGN AND METHODS: The study was undertaken in 73 morbidly obese individuals, 21 of whom had type 2 diabetes, before and 7 months after they underwent bariatric surgery and in 11 healthy, nonobese individuals. Measurements were made of the area under the curve of glucose (AUC(Glu)) by an intravenous glucose tolerance test and of oxidized LDL (oxLDL) and IgG and IgM anti-oxLDL antibodies. RESULTS: The morbidly obese patients with diabetes had significantly higher levels of oxLDL compared with the morbidly obese patients with normal fasting glucose and the control subjects and significantly lower levels of IgM anti-oxLDL antibodies. An inverse correlation was found between the levels of oxLDL and IgM anti-oxLDL antibodies (r = -0.352, P = 0.012). Although the levels of IgG and IgM anti-oxLDL antibodies rose after surgery, this increase was only significant in the diabetic patients, who experienced an improvement in their metabolic profile. Different multiple linear regression models showed that the AUC(Glu) was the main factor explaining the behavior of the levels of oxLDL and anti-oxLDL antibodies. CONCLUSIONS: We found a close association between carbohydrate metabolism and IgM anti-oxLDL antibodies, which were significantly reduced in the morbidly obese patients with diabetes. The improvement in carbohydrate metabolism after bariatric surgery led to a significant increase in the levels of IgG and IgM anti-oxLDL antibodies.

OBJECTIVE: Visfatin has shown to be increased in obesity and in type 2 diabetes. The aim of this study was to determine the change in plasma visfatin in severely obese (SO) persons after weight loss following bariatric surgery in relation to glucose concentration. RESEARCH METHODS AND PROCEDURES: Visfatin and leptin were studied in 53 SO persons (BMI, 54.4 +/- 6.8 kg/m(2)) before and 7 months after bariatric surgery and in 28 healthy persons (BMI, 26.8 +/- 3.8 kg/m(2)). All of the patients underwent bariatric surgery with biliopancreatic diversion or gastric bypass. RESULTS: The pre-surgery levels of visfatin in the SO group were greater than in the control group (55.9 +/- 39.9 vs. 42.9 +/- 16.6 ng/mL, p = 0.024). This increase was significant in the SO group with impaired fasting glucose (63.4 +/- 36.6 ng/mL) and diabetes (60.0 +/- 46.0 ng/mL). SO patients with normal fasting glucose had similar levels of visfatin to the controls. Seven months after surgery, visfatin levels were significantly increased (84.8 +/- 32.8 ng/mL, p < 0.001). This increase was independent of the pre-surgical glucose levels. The type of bariatric surgery had no influence on visfatin levels. Post-surgical visfatin was significantly correlated with the post-surgery plasma concentrations of leptin (r = 0.39, p = 0.014). DISCUSSION: Plasma levels of visfatin in the SO group were increased but only when accompanied by high glucose levels, even in the range of impaired fasting glucose. Bariatric surgery causes an increase in visfatin, which is correlated mainly with the changes produced in the leptin concentration.

BACKGROUND: The family kitchen resembles an uncontrolled laboratory experiment, and some discrepancies in the relation between the risk of hypertension and dietary fat may be partly due to the manipulation to which the fats were subjected. OBJECTIVE: We investigated whether deterioration in the quality of the cooking oils in the family household contributes to the risk of high blood pressure. DESIGN: The study was cross-sectional. Anthropometric measurements were obtained for 1226 persons aged 18-65 y who were selected randomly from the municipal census of Pizarra, Spain. An oral-glucose-tolerance test was given to 1020 of these persons. Samples of the cooking oil being used were taken from the kitchens of a random subset of 538 persons. The concentrations of polar compounds and polymers were used as markers of the deterioration of the oils. The strength of association between variables was measured by calculating the odds ratio from logistic models. RESULTS: Hypertension was strongly associated with obesity and was influenced by sex, diabetes, and age. The presence of excess polar compounds in the cooking oil and the use of sunflower oil were related to the risk of hypertension, whereas the concentration of monounsaturated fatty acids in the serum phospholipids was negatively related to this risk. These associations remained after inclusion in the models of age, sex, obesity, and the presence of carbohydrate metabolism disorder. CONCLUSIONS: The risk of hypertension is positively and independently associated with the intake of cooking oil polar compounds and inversely related to blood concentrations of monounsaturated fatty acids.
