Body composition and sexual hormones for the glucose control of autoimmune diabetes in males: are they necessary to predict diabetes-related complications?

Background: Glucose control in diabetes is essential for avoiding diabetes-related complications. Aim: To determine the impact of body composition and sexual hormones in glucose control and diabetes-related complications, in males with autoimmune diabetes. Patients and methods: Thirty-nine patients with autoimmune diabetes and flash glucose monitoring were included. A morphofunctional nutritional evaluation with bioelectrical impedance vector analysis (BIVA), abdominal adipose tissue ultrasound, rectus femoris ultrasound and biochemical parameters, was performed. Results: Strong, positive correlations were observed between body composition parameters, biochemical variables and sexual hormones (p<0.05). Adipose tissue measured by BIVA and ultrasound was more significantly associated with glucose control (including time in range >70%, glucose variability <36% determined by flash glucose monitoring; p<0.05) and the presence of microvascular/macrovascular complications (p<0.05) than lean mass. After adjusting by the duration of diabetes, BMI, abdominal circumference, fat mass and phase angle increased the risk for microvascular complications (OR 1.32(1.00 - 1.73), OR 1.06(1.00 - 1.12), OR 1.14(1.01 - 1.20), 0R 0.3(0.10 - 0.91) respectively; for macrovascular complications: BMI OR 1.38(1.04 - 1.84) and fat mass OR 1.26(1.00 - 1.58)]. Sexual hormone levels did not influence on glucose control or the development of diabetes-related complications. Conclusion: Anthrpometric parameters, especially adipose tissue, were associated with glucose control and variability determined by flash glucose monitoring. Furthermore, changes in fat and lean mass were associated with the presence of microvascular and macrovascular complications. Thus, a comprehensive nutritional evaluation might be useful for the evaluation of males with autoimmune diabetes, in order to identify patients with increased risk of complications.

Mediterranean Diet, Vitamin D, and Hypercaloric, Hyperproteic Oral Supplements for Treating Sarcopenia in Patients with Heart Failure-A Randomized Clinical Trial.

BACKGROUND: Malnutrition and sarcopenia frequently affect patients with heart failure (HF), in which clinical outcomes and survival is decreased. Thus, appropriate nutritional screening and early nutrition support are highly recommended. Currently, nutritional support is not a standard of care in patients with HF, and the use of commercially available oral supplements (OSs) could provide an additional benefit to medical treatment in these patients. AIM: To compare the effect of the Mediterranean diet in combination with hypercaloric, hyperproteic OS in patients with HF. PATIENTS AND METHODS: An open label, controlled clinical study in which patients were randomly assigned to receive a Mediterranean diet (control group) vs. hypercaloric, hyperproteic OS (intervention group) for twenty-four weeks. Thirty-eight patients were included; epidemiological, clinical, anthropometric, ultrasound (muscle echography of the rectus femoris muscle of the quadriceps and abdominal adipose tissue), and biochemical evaluations were performed. All patients received additional supplementation with vitamin D. RESULTS: Baseline malnutrition according to the GLIM criteria was observed in 30% of patients, while 65.8% presented with sarcopenia. Body cell mass, lean mass, and body mass increased in the intervention group (absolute increase of 0.5, p = 0.03, 1.2 kg, p = 0.03, and 0.1 kg, p = 0.03 respectively). In contrast, fat mass increased in the control group (4.5 kg, p = 0.05). According to the RF ultrasound, adipose tissue, muscle area, and circumference tended to decrease in the intervention group; it is probable that 24 weeks was too short a period of time for evaluating changes in muscle area or circumference, as previously observed in another group of patients. In contrast, functionality, determined by the up-and-go test, significantly improved in all patients (difference 12.6 s, p < 0.001), including the control (10 s improvement, p < 0.001) and the intervention group (improvement of 8.9 s, p < 0.001). Self-reported QoL significantly increased in all groups, from 68.7 ± 22.2 at baseline to 77.7 ± 18.7 (p = 0.01). When heart functionality was evaluated, LVEF increased in the whole cohort (38.7 ± 16.6 vs. 42.2 ± 8.9, p < 0.01); this increase was higher in the intervention group (34.2 ± 16.1 at baseline vs. 45.0% ± 17.0 after 24 weeks, p < 0.05). Serum values of NT-proBNP also significantly decreased in the whole cohort (p < 0.01), especially in the intervention group (p = 0.02). After adjusting by age and sex, nutritional support, baseline LVEF, NT-proBNP, and body composition parameters of functionality tests were not associated with mortality or new hospital admissions in this cohort. CONCLUSION: Nutritional support with hypercaloric, hyperproteic OS, Mediterranean diet, and vitamin D supplementation were associated with decreased NT-proBNP and improvements in LVEF, functionality, and quality of life in patients with HF, despite a significant decrease in hospital admissions.

Fish Oil Enriched Intravenous Lipid Emulsions Reduce Triglyceride Levels in Non-Critically Ill Patients with TPN and Type 2 Diabetes. A Post-Hoc Analysis of the INSUPAR Study.

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.

[Nutritional approach in systemic sclerosis: report of a case]. / Abordaje nutricional en esclerodermia: a propósito de un caso.

INTRODUCTION: Background: systemic sclerosis is a rare systemic acquired disease with a complex pathogenesis which compromises multiple organs. The nutritional approach to treat patients with this disease is not clearly stablished due to its low prevalence. Case report: we present the case of a 37-year-old woman diagnosed with systemic sclerosis with gastrointestinal compromise, 40% weight loss since diagnosis and severe anemia. Despite oral supplementation, placement of a gastrostomy feeding tube and medical therapy with octreotide, her nutritional requirements are not achieved, so we suggest home parenteral nutrition to complete the nutritional support. Discussion: the severe intestinal affection in this patient made it necessary to turn to the parenteral access because of the oral intolerance secondary to the intestinal pseudo-obstruction. In these cases, the lack of etiological treatment makes home parenteral nutrition play an important role in the nutritional approach.

INTRODUCCIÓN: Introducción: la esclerodermia es una enfermedad sistémica adquirida poco frecuente, con una patogenia compleja que compromete a numerosos órganos. El abordaje nutricional no está claramente establecido debido a su baja prevalencia. Caso clínico: presentamos el caso de una mujer de 37 años diagnosticada de esclerodermia difusa con amplia afectación gastrointestinal, pérdida de 40% de peso desde el diagnóstico y anemia grave. A pesar de la toma de suplementos orales, la nutrición a través de gastrostomía y el uso de octreótide, no se alcanzan los requerimientos nutricionales, por lo que se plantea el uso de nutrición parenteral domiciliaria junto al resto de tratamientos. Discusión: esta paciente, la progresión de la afectación digestiva debida a la esclerodermia hizo necesario recurrir al aporte parenteral debido a la intolerancia oral a causa de la pseudooclusión intestinal. En estos casos, la ausencia de tratamiento etiológico hace que la nutrición parenteral domiciliaria juegue un papel importante en el soporte nutricional.

[Recommendations of the GARIN group for dietary managing of patient with chronic kidney disease]. / Recomendaciones del grupo GARIN para el tratamiento dietético de los pacientes con enfermedad renal crónica.

INTRODUCTION: Background and objectives: by means of this update, the GARIN working group aims to define its position regarding the dietary treatment of patients with chronic kidney disease (CKD). In this area there are many aspects of uncertainty. Material and methods: bibliographical review and specific questions in advance were discussed and answered at a meeting in the form of conclusions. Results: the therapeutic action must be individualized and taking into account the degree of renal failure that the patient presents and their comorbidities. Regarding nutritional medical therapy, our group proposes three different levels of action, in which the recommendations of protein intake, fiber, fatty acids or potassium are different. In addition, we suggest using the phosphorus/protein ratio concept in adjusting the diet of the patient with CKD. We give recommendations regarding treatment in diabetes and artificial supplementation. Conclusions: these recommendations about dietary issues in patients with CKD can add value to clinical work.

INTRODUCCIÓN: Introducción y objetivos: en el tratamiento dietético de los pacientes con enfermedad renal crónica (ERC) existen muchas áreas de incertidumbre.

Gastrostomía endóscopica percutánea en esclerosis lateral amiotrófica; experiencia en un hospital de tercer nivel / Percutaneous endoscopic gastrostomy in amyotrophic lateral sclerosis, experience in a district general hospital

Introducción: La Esclerosis Lateral Amiotrófica (ELA) es una enfermedad degenerativa neurológica con afectación de la vía piramidal, produciendo trastornos motores progresivos que evolucionan hasta la parálisis. Estos pacientes pueden asociar disfagia, precisando soporte nutricional a través de de sonda nasogástrica o Gastrostomía Endoscópica Percutánea (PEG). La PEG está asociada con aumento de la supervivencia, sin embargo la evidencia acerca del momento óptimo para su colocación es escasa. Objetivo: Analizar las características de los pacientes con ELA en el momento de colocación de la PEG y su evolución. Material y métodos: Estudio descriptivo retrospectivo. Se incluyeron pacientes con diagnóstico de ELA y PEG valorados durante los años 2005-2014 en nuestro hospital. Se analizaron parámetros nutricionales y respiratorios, y evolución de los pacientes. Los resultados se analizaron en el programa SPSS15. Resultados: 37 pacientes fueron incluidos (56,8% hombres, 43,2% mujeres) con una edad media al diagnóstico 60 años, y edad media de colocación de PEG de 63,1 años, el 48,6% debutó con afectación espinal y el 51,4%, con bulbar. El 43,2% de los pacientes recibieron suplementos previa colocación de PEG durante un promedio de 11,3 meses. La capacidad vital forzada (CVF) media al diagnóstico fue del 65,45±13,67%, evolucionando desfavorablemente hasta un 39,47±14,69% en el momento de colocación de la PEG. El 86,5% de los pacientes precisaron soporte respiratorio con ventilación mecánica no invasiva (VMNI). El 86,5% presentaron disfagia, el 64,9% pérdida de peso > 5-10% de su peso habitual, el 8,1% IMC bajo, el 27% parámetros bioquímicos de desnutrición y el 73% empeoramiento de función respiratoria, por tanto, el 100% cumplían criterios de colocación de PEG según nuestro protocolo. La duración de la nutrición enteral fue de 10,1 meses con una mortalidad del 50% en los primeros 6 meses de la colocación de la PEG. Conclusiones: Evidenciamos una demora de 3 años entre el diagnóstico y la colocación de la PEG, con una supervivencia del 50% a los 6 meses de la realización de la misma. Más estudios son necesarios para determinar si una colocación más precoz podría aumentar la supervivencia (AU)

Background: Amyotrophic Lateral Sclerosis (ALS) is a degenerative disorder that affects the pyramidal tract, producing progressive motor dysfunctions leading to paralysis. These patients can present with dysphagia, requiring nutritional support with a nasogastric tube or Percutaneous Endoscopic Gastrostomy (PEG). PEG is associated with increased survival rates. However, the timing of PEG placement remains a significant issue for clinicians. Objective: To analyse the characteristics of ALS patients at the moment of PEG placement and their progression. Methods and materials: Descriptive retrospective study including patients diagnosed with ALS and PEG who were assessed during the 2005-2014 period in our hospital. Nutritional parameters and respiratory function were assessed for all patients, as well as their progression. The data was analysed using SPSS15. Results: 37 patients were included (56.8% men, 43.2% women) with an average age of 60 at diagnosis, and an average age of 63.1 at PEG placement. 48.6% started with spinal affection and 51.4%, with bulbar affection. 43.2% of the patients received oral nutritional supplements prior to PEG placement for a mean period of 11.3 months. The mean forced vital capacity at diagnosis was 65.45±13.67%, with a negative progression up to 39.47±14.69% at the moment of PEG placement. 86.5% of patients required non-invasive positive-pressure ventilation. 86.5% presented with dysphagia, 64.9% with weight loss > 5-10% from their usual weight, 8.1% with low Body Mass Index, 27% with malnutrition and 73% with aworsened breathing function; therefore, 100% met the criteria for PEG placement according to our protocol. The period on enteral feeding was extended for 10.1 months with a mortality of 50% during the first 6 months from PEG placement. Conclusions: There is evidence of a 3-year delay between diagnosis and PEG placement, with a survival rate of 50% at 6 months from PEG insertion. Further studies are required to establish whether an earlier placement might increase survival rates (AU)

[Screening for Cushing's syndrome in obese patients; is it really necessary?]. / Despistaje rutinario de síndrome de Cushing en pacientes con obesidad mórbida: ¿es realmente necesario?

to be more frequent among patients with metabolic syndrome. Previous studies have suggested to perform a routine screening for CS in obese patients; however, more recent reports only recommend a case-finding approach in patients with uncontrolled diabetes and hypertension, despite appropriate treatment. Objective: The aim of this study was to evaluate the prevalence of unsuspected CS in morbidly obese patients in an outpatient's clinic. Patients and methods: Retrospective case-note study. We reviewed the medical records of morbidly obese patients referred to our clinic prior to bariatric surgery between january 2001 and december 2011. All patients had a complete medical history including physical examination, and 399 underwent screening for CS as part of our pre-surgical protocol. As screening for autonomous cortisol secretion, we performed an overnight 1 mg Dexamethasone Suppression Test (DST). Serum cortisol < 1.8 µg/dl was the cut-off point for normal suppression. Results: 399 patients (308 female; mean age 41.9 ± 10.5 years; mean BMI 51.5 ± 8.4 kg/m2). In the retrospective analysis, prediabetes and diabetes mellitus were observed in 10.3% and 27.8% respectively. In 21 of 399 patients, screening was considered to be abnormal. Eight of these 21 patients had subsequent normal 24h Urinary Free Cortisol (UFC) levels (150 µg/24h). In 13 of 20 patients, we repeated an overnight 1mg DST, on suspicion of failing to take the dexamethasone correctly. Three patients failed to suppress their cortisol levels, two of them were on carbamazepine, which was considered to be a false positive result. The other patient with abnormal UFC levels was diagnosed with CS (0.26%), whose cause was a pituitary microadenoma. Conclusion: A low proportion of patients with morbid obesity were found to have CS. Our findings suggest that morbidly obese patients should not be routinely screened for CS.

Introducción: El síndrome de Cushing (SC) es más frecuente en pacientes con síndrome metabólico. Estudios previos han sugerido que es necesario realizar un despistaje de SC en pacientes obesos; sin embargo, estudios más recientes sólo recomiendan el despistaje en pacientes con hipertensión o diabetes mal controlados, a pesar de tratamiento. Objetivo: Evaluar la prevalencia de SC oculto en pacientes con obesidad mórbida. Pacientes y métodos: Estudio observacional retrospectivo en el que se incluyeron 399 pacientes que iban a someterse a cirugía bariátrica. A todos los pacientes se les realizó una historia clínica completa, incluyendo exploración física y test de Nugent, como parte del protocolo precirugía. Resultados: 399 pacientes (308 mujeres, edad media 41,9 ± 10,5 años; IMC medio 51,5 ± 8,4 kg/m2). El 10,3% de los pacientes presentaban prediabetes y el 27,8% diabetes. En 21 de los 399 pacientes, el despistaje fue anormal. En 8 pacientes, medimos cortisol libre en orina de 24 horas (CLU), siendo en todos normal al menos en dos ocasiones (CLU < 150 mcg/24 h), lo que descartaba SC. En 13 pacientes, repetimos el test de Nugent; sólo en 3, el test resultó patológico. Dos de los pacientes estaban en tratamiento con carbamacepina, lo que se consideró un falso positivo. El otro paciente se diagnosticó de Enfermedad de Cushing. Conclusión: La prevalencia de SC fue muy baja en pacientes con obesidad mórbida. Nuestros datos sugieren que no se debería realizarse un despistaje de SC de forma rutinaria.

[Bariatric surgery in inflammatory bowel disease; case report and review of the literature]. / Cirugía bariátrica en enfermedad inflamatoria intestinal; presentación de un caso clínico y revisión de la literatura.

Inflammatory bowel disease (IBD) is rarely associated with obesity, as malabsorption is a common feature of these diseases (1). However, some patients may experience morbid obesity and associated complications refractory to dietary treatment and benefit from bariatric surgery. It has even been postulated that surgery may result in improvement of IBD by reducing inflammatory markers (2). However, patients may experience a higher incidence of complications following surgery in the context of immunosuppressive therapy and prior malabsorption. Therefore, if surgery is performed, careful patient selection and individualization of technique are essential. We present a patient diagnosed with ulcerative colitis who presented severe protein malnutrition after bariatric surgery type bilio-pancreatic diversion and review the available literature.

La Enfermedad Inflamatoria Intestinal (EII) raramente se asocia a obesidad, ya que la malabsorción es una característica frecuente de este grupo de patologías (1). Sin embargo, algunos pacientes pueden padecer obesidad mórbida asociada a complicaciones y refractaria a tratamiento dietético y beneficiarse de la cirugía bariátrica. Incluso se ha postulado que podría producirse una mejoría de la EII al disminuir los marcadores inflamatorios tras la cirugía (2). No obstante, los pacientes pueden experimentar mayor incidencia de complicaciones tras la cirugía en el contexto de terapias inmunosupresoras y agravamiento de la malabsorción previa. Por ello, si se realiza la cirugía, la cuidadosa selección de los pacientes y la individualización de la técnica a realizar son imprescindibles. Presentamos una paciente diagnosticada de Colitis Ulcerosa que presenta desnutrición proteica severa tras cirugía bariátrica tipo derivación bilio-pancreática y realizamos una revisión de la literatura disponible.
