Utility of abdominal ultrasound for diagnosis of hepatic steatosis in patients with morbid obesity.

Metabolic dysfunction-associated fatty liver disease is the most common cause of liver disease in our environment. The gold standard for diagnosis continues to be liver biopsy, although, since it is an invasive test, the most commonly used test for the initial diagnosis of steatosis is abdominal ultrasound. We present the results on the diagnostic utility of ultrasound for the detection of steatosis in the population of morbidly obese patients who underwent bariatric surgery from 2004 to 2019 in our centre.

Analysis of psychometric questionnaires used in patient selection for bariatric surgery.

INTRODUCTION: In severe forms of obesity there is a high prevalence of psychopathological comorbidity. Psychiatric evaluation is an important component of comprehensive obesity care and contributes to optimizing therapeutic results after bariatric surgery. OBJECTIVE: To assess the effectiveness of psychometric tests used in the protocol for selecting patients for bariatric surgery. MATERIAL AND METHODS: Retrospective naturalistic observational study of 100 patients who were candidates for bariatric surgery. Patients who complete the psychometric protocol and the psychiatric interview between January 2019 and June 2021 are included. Two groups are formed: those considered unfit for any psychopathological reason and those considered fit. To evaluate the effectiveness of the tests used, ROC curves will be used. The sensitivity and specificity values of each test used will be obtained. RESULTS: 97 patients included, aged between 20 and 61 years, 64.9% women. 51.5% had a family history and 38.1% a personal history of any psychiatric disorder. Regarding the area under the curve, the scales that presented a value greater than 0.7 were the YFAS total score (0.771), HADS-D (0.757), the Edinburgh Bulimia total score (0.747), the severity score of YFAS (0.722) and Edinburgh Bulimia Severity Score (0.705). The most frequent diagnoses as a cause of exclusion were Food Addiction 8 (20.5%) and Generalized Anxiety Disorder (GAD) 6 (15.5%). CONCLUSIONS: The YFAS, BITE and HADS-A scales were useful to discriminate those patients considered unsuitable for bariatric surgery for any psychopathological cause.

[Process of medical nutrition therapy]. / Proceso de tratamiento médico nutricional.

Introduction: Medical nutrition therapy is a very useful tool in maintaining and recovering the health of patients with disease-related malnutrition, although its implementation can be complex and is not without risks. Quality processes are understood as sets of activities that are related or interact to transform input elements into results. From the SENPE Management Work Group we present the process of medical nutrition therapy (PMNT), which aims to facilitate the management of clinical nutrition of a multidisciplinary nutrition support team in a hospital setting. This paper describes the seven sub-processes PMNT is comprised of, in addition to a previous nutritional screening sub-process. Each sub-process is divided into a first section with a technical sheet detailing its general aspects, while a second section proposes key objectives, quality indicators, and standards for their evaluation. .

Aetiological diagnosis of hyponatraemia in non-critical patients on total parenteral nutrition: A prospective multicentre study.

BACKGROUND: In patients receiving total parenteral nutrition (TPN), the frequency of hyponatraemia is high. However, the causes of hyponatraemia in TPN have not been elucidated, although diagnosis is required for appropriate therapy. The aim of this study is to describe the aetiology of hyponatraemia in non-critical hospitalised patients receiving TPN. METHODS: Prospective multicentre study in 19 Spanish hospitals. Non-critically hyponatraemic patients receiving TPN and presenting hyponatraemia over a 9-month period were studied. Data collected included sex, age, previous comorbidities, and serum sodium levels (SNa) before and following TPN initiation. Parameters for study of hyponatraemia were also included: clinical volaemia, the presence of pain, nausea, gastrointestinal losses, diuretic use, oedema, renal function, plasma and urine osmolality, urinary electrolytes, cortisolaemia, and thyroid stimulating hormone. RESULTS: 162 patients were included, 53.7% males, age 66.4 (SD13.8) years. Volume status was evaluated in 142 (88%): 21 (14.8%) were hypovolaemic, 96 (67.6%) euvolaemic and 25 (17.6%) hypervolaemic. In 111/142 patients the analytical assessment of hyponatraemia was completed. Hypovolaemic hyponatraemia was secondary to GI losses in 10/111 (9%), and to diuretics in 3/111 (2.7%). Euvolaemic hyponatraemia was due to Syndrome of Inappropriate Antidiuretic Hormone secretion (SIADH) in 47/111 (42.4%), and to physiological stimuli of Arginine Vasopressin (AVP) secretion in 28/111 (25.2%). Hypervolaemic hyponatraemia was induced by heart failure in 19/111 (17.1%), cirrhosis of the liver in 4/111 (3.6%). CONCLUSIONS: SIADH was the most frequent cause of hyponatraemia in patients receiving TPN. The second most frequent cause was physiological stimuli of AVP secretion induced by pain/nausea.

Long-Term Effects of Bariatric Surgery on Gut Microbiota Composition and Faecal Metabolome Related to Obesity Remission.

Obesity is one of the main worldwide public health concerns whose clinical management demands new therapeutic approaches. Bariatric surgery is the most efficient treatment when other therapies have previously failed. Due to the role of gut microbiota in obesity development, the knowledge of the link between bariatric surgery and gut microbiota could elucidate new mechanistic approaches. This study aims to evaluate the long-term effects of bariatric surgery in the faecal metagenome and metabolome of patients with severe obesity. Faecal and blood samples were collected before and four years after the intervention from patients with severe obesity. Biochemical, metagenomic and metabolomic analyses were performed and faecal short-chain fatty acids were measured. Bariatric surgery improved the obesity-related status of patients and significantly reshaped gut microbiota composition. Moreover, this procedure was associated with a specific metabolome profile characterized by a reduction in energetic and amino acid metabolism. Acetate, butyrate and propionate showed a significant reduction with bariatric surgery. Finally, correlation analysis suggested the existence of a long-term compositional and functional gut microbiota profile associated with the intervention. In conclusion, bariatric surgery triggered long-lasting effects on gut microbiota composition and faecal metabolome that could be associated with the remission of obesity.

Nutritional profile of multiple sclerosis / Perfil nutricional de la esclerosis múltiple

Background: multiple sclerosis (MS) is an inflammatory, neurodegenerative disease of the central nervous system. Weight loss and malnutrition are prevalent in advanced stages of MS. Objective: the aim of this study was to define the nutritional profile in moderate-advanced MS (especially by documenting malnutrition) and its evolution. Methods: a case-control study was designed; cross-sectional observational study was complemented by a 12-month prospective longitudinal observational study of MS patients. Nutritional status was evaluated by collecting clinical, anthropometric, dietary and analytical data. Results: one hundred and twenty-four patients with MS and 62 controls were recruited; 8% of the patients were malnourished or at risk of malnutrition. Only MS patients with advanced disability needed nutritional support. During the follow-up, five patients died and four of them received nutritional support. Conclusions: malnutrition was unusual in our sample of patients with moderate-advanced MS. The need for nutritional support is related to dysphagia in patients with advanced neurological disability. The nutritional status of patients with moderate-advanced MS is defined by a tendency to overweight and by the decrease in basal energy expenditure and handgrip strength test in relation to the loss of muscle mass. The deficient intake of polyunsaturated fatty acids, fiber and vitamin D is exacerbated in the evolution of the disease

Introducción: la esclerosis múltiple (EM) es una enfermedad inflamatoria y neurodegenerativa del sistema nervioso central. La pérdida de peso y la malnutrición son frecuentes en fases avanzadas de la EM. Objetivo: el objetivo de este estudio fue definir el perfil nutricional de la EM en estadio moderado-avanzado (especialmente, documentando la malnutrición) y su evolución a 12 meses. Métodos: se realizó un estudio de casos-controles; el estudio observacional transversal se complementó con un estudio observacional longitudinal prospectivo a 12 meses de los pacientes con EM. El estado nutricional se evaluó mediante la recogida de datos clínicos, antropométricos, dietéticos y analíticos. Resultados: se incluyeron en el estudio 124 pacientes con EM y 62 controles. El 8% de los pacientes estaban desnutridos o en riesgo de desnutrición. Solo los pacientes con EM con discapacidad avanzada necesitaban soporte nutricional. Durante el seguimiento, cinco pacientes fallecieron y cuatro de ellos estaban recibiendo soporte nutricional. Conclusiones: la desnutrición es infrecuente en nuestra muestra de pacientes con EM moderada-avanzada. La necesidad de apoyo nutricional está relacionada con la disfagia en pacientes con discapacidad neurológica avanzada. El estado nutricional de los pacientes con EM moderada-avanzada se define por una tendencia al sobrepeso y por valores bajos en el gasto energético basal y en la dinamometría manual en relación con la pérdida de masa muscular. La ingesta deficiente de ácidos grasos poliinsaturados, fibra y vitamina D se acentúa en la evolución de la enfermedad

Development of hyponatremia in non-critical patients receiving total parenteral nutrition: A prospective, multicenter study.

BACKGROUND & AIMS: Hyponatremia is frequent in hospitalized patients, especially in those receiving total parenteral nutrition (TPN). Furthermore, the presence of hyponatremia is associated with increased morbimortality in both groups. The goal of this study is to describe the prevalence of hyponatremia developing during TPN in non-critical patients, and identify risk factors for its appearance. METHODS: This prospective multicenter study involved 19 Spanish hospitals. Noncritically-ill patients prescribed TPN over a 9-month period were studied. Variables analyzed demographic characteristics, prior comorbidities, drug therapy, PN composition, additional iv fluids, and serum sodium levels. RESULTS: A total of 543 patients were recruited, 60.2% males. Age: 67 (IR 57-76). Of 466/543 who were eunatremic when starting TPN, 18% developed hyponatremia (serum sodium < 135 mmol/L) during TPN. Independent risk factors identified by logistic regression analysis: female (OR 1.74 [95% CI = 1.04-2.92], p = 0.036); severe malnutrition (OR 2.15 [95% CI = 1.16-4.35], p = 0.033); opiates (OR 1.97 [95% CI = 1.10-3.73], p = 0.036); and nausea/vomiting (OR 1.75 [95% CI = 1.04-2.94], p = 0.036). CONCLUSIONS: Previously eunatremic patients frequently develop hyponatremia while receiving TPN. In this group, severe malnutrition is an independent risk factor for hyponatremia, as well as previously described risk factors: opiates, nausea/vomiting, and female gender.

Antecedentes: La imprecisión en la terminología dentro de la nutrición clínica puede acarrear malas interpretaciones entre los distintos profesionales. Objetivo: Por esta razón, la Sociedad Española de Endocrinología y Nutrición (SEEN) ha promovido la realización del presente trabajo, el primero sobre terminología y definiciones en nutrición artificial clínica (enteral y parenteral) publicado en castellano. Métodos: Un total de 47 especialistas en Endocrinología y Nutrición expertos en la materia, miembros del Área de Nutrición de la SEEN, han participado entre los meses de abril y septiembre de 2016. Tras una revisión bibliográfica sistematizada fueron propuestos 52 conceptos, ampliándose a 54 por las coordinadoras y finalmente a 57 por el grupo de trabajo: 13 de carácter general, 30 referidos a la nutrición enteral y 14 a la parenteral. En una fase posterior se determinó el grado de acuerdo mediante un proceso Delphi de 2 circulaciones. Finalmente fue ratificado mediante un análisis de consistencia y concordancia. Resultados: En 54 de los 57 términos hubo un acuerdo muy consistente y resultaban concordantes. Solo 3 no presentaron concordancia, de los que 2 eran muy consistentes y uno inconsistente. En conclusión, queda consensuada la definición de 54 términos básicos en la práctica de la nutrición clínica (AU)

Background: Imprecision in terms used in the field of clinical nutrition may lead to misinterpretations among professionals. Objective: For this reason, the Spanish Society of Endocrinology and Nutrition (SEEN) promoted this document on the terms and definitions used in clinical artificial nutrition (enteral and parenteral), establishing an agreement between Spanish experts of this specialty. Methods: Forty-seven specialists in endocrinology and nutrition, members of the Nutrition Area of the SEEN, participated between April and September 2016. After a systematic literature review, 52 concepts were proposed. The coordinators included two additional concepts, and 57were finally selected by the working group: 13 of a general nature, 30 referring to enteral nutrition and 14 to parenteral nutrition. The degree of agreement was subsequently determined using a two-round Delphi process. It was finally ratified by consistency and concordance analysis. Results: Fifty-four of the 57 terms had a very consistent agreement and were concordant. Only three showed no concordance, of whom two were very consistent and one inconsistent. In conclusion, there was consensus in the definition of 54 basic terms in the practice of clinical nutrition (AU)

Disability and its influence in nutritional assessment tools in elderly people living in nursing homes.

INTRODUCTION: Poor nutritional status is associated with increased morbidity and mortality, especially in older people. OBJECTIVE: The aim of this study was to assess nutritional status in elderly nursing home residents with different nutritional test, and to determine which parameters used for nutritional assessment can be carried out in this population, which usually have a high prevalence of functionally dependent residents. METHODS: A cross-sectional study was performed in 383 elderly. The nutritional assessment tools used were the Mini Nutritional Assessment (MNA), the new ESPEN consensus definition of malnutrition, and the tool for Controlling Nutritional Status (CONUT). Moreover, the ability to perform basic activities of daily living was assessed with the Barthel index (BI). RESULTS: According to BI, 78.9% had a total dependence and only 20.9% could be weighed and heighed. The prevalence of malnutrition with MNA, ESPEN and CONUT was 21.3%, 17.6% and 20.7%, respectively. The agreement between MNA vs ESPEN criteria was moderate (kappa = 0.483), but with CONUT was low. CONCLUSIONS: Nursing homes had a high percentage of totally dependent residents. This high degree of functional dependence made difficult to obtain some anthropometric parameters such as weight and height, which are essential to carry out most nutritional tests. MNA, CONUT and the new ESPEN criteria of malnutrition showed a high prevalence of malnutrition and risk of malnutrition in subjects in which they could be performed.

Organization and management of clinical nutrition in Spain. How do we assess the quality of our activities?

INTRODUCTION: Among the objectives of the SENPE Management Working Group is the development of knowledge and tools related to the evaluation of health outcomes. OBJECTIVES: To obtain an approximate profile of clinical nutrition in hospitals in Spain, specifically concerning its organization, endowment, activities and quality indicators. METHODS: A cross-sectional study conducted in 2013 through a structured survey sent to a random sample of 20% of hospitals from the network of the National Health System of Spain, stratified by the number of hospital beds. RESULTS: The overall response rate was 67% (83% in hospitals with over 200 beds). In 65% of hospitals, clinical nutrition is run by a coordinated team or unit, with a doctor working full time in only 50% of centers. Other professionals are often not recognized as part of the team or unit. There is a specialized monographic nutrition clinic in 62% of centers and 72% have more than 40 new inpatient consultations per month (27% with more than 80 per month). Among the centers with a clinical nutrition team or unit, there is a greater tendency to monitor quality indicators related to clinical practice. CONCLUSIONS: There is widespread addition of clinical nutrition teams and units in hospitals in Spain. However, truly multidisciplinary organization is not often found. High workloads are assumed in relation to staffing levels. The existence of well-organized structures may be associated with benefits that directly affect attendance.

Introducción: el Grupo de Trabajo de Gestión de SENPE tiene entre sus objetivos el conocimiento y desarrollo de herramientas para la evaluación de resultados en salud. Objetivos: obtener un perfil aproximado de los equipos de Nutrición Clínica en los hospitales de España, específicamente sobre su organización, dotación, actividad e indicadores de calidad. Métodos: estudio transversal realizado en 2013 mediante una encuesta estructurada remitida a una muestra aleatoria del 20% de hospitales de la red del Sistema Nacional de Salud, estratificada por número de camas de hospitalización. Resultados: la tasa de respuesta global fue del 67% (83% en centros con más de doscientas camas). En el 65% de los centros, la Nutrición Clínica está a cargo de un equipo coordinado o una unidad, con médico a tiempo completo en solo un 50% de centros. Con frecuencia no se reconocen otros profesionales como parte del equipo o unidad. Existen consultas monográficas especializadas en nutrición clínica en un 62% y se atienden más de 40 nuevas consultas mensuales de hospitalización en el 72% de los centros (más de 80 en el 27%). Entre los centros con equipo de Nutrición se observa una mayor tendencia al seguimiento de indicadores de calidad relacionados con la práctica clínica. Conclusiones: la incorporación de equipos y unidades de Nutrición Clínica es amplia en los hospitales de España. No es frecuente una verdadera organización multidisciplinar y se asumen cargas de trabajo elevadas en relación a las dotaciones de personal. La existencia de estructuras bien organizadas puede acompañarse de beneficios que repercuten directamente en la calidad de la asistencia (AU)

Long-term outcome of multimodal therapy for giant prolactinomas.

Giant prolactinomas are rare tumors characterized by their large size, compressive symptoms, and extremely high prolactin secretion. The aim of this study is to describe our experience with a series of 16 giant prolactinomas cases in terms of clinical presentation, therapeutic decisions, and final outcomes. Retrospective analysis of adult patients diagnosed with giant prolactinomas at the endocrine departments of three university tertiary hospitals. We included 16 patients (43.7 % women); mean age at diagnosis: 42.1 ± 21 years. The most frequent presentation was compressive symptoms. The delay in diagnosis was higher in women (median of 150 months vs. 12 in men; p = 0.09). The mean maximum tumor diameter at diagnosis was 56.9 ± 15.5 mm, and mean prolactin levels were 10,995.9 ± 12,157.8 ng/mL. Dopamine agonists were the first-line treatment in 11 patients (mean maximum dose: 3.9 ± 3.2 mg/week). Surgery was the initial treatment in five patients and the second-line treatment in six. Radiotherapy was used in four cases. All patients but one, are still with dopamine agonists. After a mean follow-up of 9 years, prolactin normalized in 7/16 patients (43.7 %) and 13 patients (81 %) reached prolactin levels lower than twice the upper limit of normal. Mean prolactin level at last visit: 79.5 ± 143 ng/mL. Tumor volume was decreased by 93.8 ± 11.3 %, and final maximum tumor diameter was 18.4 ± 18.8 mm. Three patients are actually tumor free. Giant prolactinomas are characterized by a large tumor volume and extreme prolactin hypersecretion. Multimodal treatment is frequently required to obtain biochemical and tumor control.

Insulin resistance and metabolic syndrome are related to non-alcoholic fatty liver disease, but not visceral adiposity index, in severely obese patients.

The visceral adiposity index (VAI) is a marker of visceral fat distribution and dysfunction. Visceral adiposity is related to nonalcoholic fatty liver disease (NAFLD); however, there is some controversy regarding the association between VAI and NAFLD.The aim of this study was to analyse the relationship between VAI and NAFLD and to describe the related factors in severely obese patients. A total of 139 patients who underwent bariatric surgery were included in this cross-sectional study. Liver biopsy was performed during surgery. Univariate and multivariate analysis were conducted to study the features related to VAI. A univariate analysis was conducted to identify which factors were associated with liver histology. In the univariate analysis, steatosis, liver inflammation, non-alcoholic steatohepatitis (NASH) and fibrosis were associated with VAI. In the multivariate analysis, only HOMA (Beta: 0.06; p < 0.01) and metabolic syndrome (Beta: 1.23; p < 0.01) were related to VAI. HOMA, the presence of metabolic syndrome, and waist circumference (WC) were statistically related to the NAFLD activity score (NAS score): HOMA: 0-2: 5.04; 3-4: 7.83; > or = 5: 11,32; p < 0.01; MS: 0-2: 37 %; 3-4: 33.3 %; > or = 5: 76%; p < 0.01; WC: 0-2: 128.7 cm; 3-4: 130.7; > or = 5: 140.6; p < 0.01). For the prediction of NASH (NAS score > or = 5), the AUROC curve were 0.71 (CI 95 %: 0.63-0.79) for VAI and 0.7 (CI 95 %: 0.62-0.78) for WC. In conclusion, HOMA, WC and metabolic syndrome are related to liver histology in patients with severe obesity. In the multivariate analysis, VAI was associated with HOMA and metabolic syndrome, but not with liver histology.
