Relationship between Mediterranean Diet and Phase Angle in a Sample of Patients with Obesity and Metabolic Syndrome.

INTRODUCTION: The potential influence of a Mediterranean diet (MD) on PhA values has been little researched. The aim of this study was to investigate the association between adherence of a MD and PhA on adult sample population with obesity and metabolic syndrome. METHODS: We conducted a cross-sectional study in 331 patients with obesity and metabolic syndrome. Anthropometrics' data (weight, height, body mass index, and waist circumference), bioelectrical bioimpedance (BIA) parameters (resistance reactance, PhA, fat mass [FM], fat-free mass [FFM], skeletal muscle mass [SMM]), and biochemical parameters were recorded. Dietary intakes with a 3-day written food records and MD adherence with a validated 14-item questionnaire were evaluated. Patients were divided into two groups by median value of PhA. RESULTS: Percentage of patients with high MD adherence (score >7) in high PhA group was 77.2% and in low PhA group was 41.4% (odds ratio 1.91, 95% CI = 1.27-3.54; p = 0.01). Total fat intake (saturated, monounsaturated, and polyunsaturated fats), protein intake, and cholesterol intake were higher in high PhA group than low PhA group. Total score of MD was higher in high PhA than low PhA group (3.5 ± 1.1 points; p = 0.04). FFM (3.3 ± 0.9 kg; p = 0.01), FFM index (3.9 ± 1.1 kg/m2; p = 0.01), SMM (4.6 ± 1.2 kg; p = 0.01) and SMM index (3.3 ± 0.7 kg/m2; p = 0.03) were higher in subjects of high adherence of MD group than subjects of low adherence. FM (-3.2 ± 1.1 kg; p = 0.03) was lower in subjects with good adherence to MD. MD score (Beta 1.71, CI 95% 1.06-2.16), FFM (Beta 3.99, CI 95% 1.87-7.16), and SMM (Beta 4.21, CI 95% 1.76-8.19) remained in the multivariate model. CONCLUSION: We concluded that a high adherence to a MD in subjects with obesity and metabolic syndrome is associated with values of PhA.

Prevalence of Risk of Malnutrition and Risk of Sarcopenia in a Reference Hospital for COVID-19: Relationship with Mortality.

INTRODUCTION: Many elderly patients with COVID-19 are at risk of malnutrition. The aim of our study was to evaluate the risk of malnutrition and sarcopenia in elderly COVID-19 patients with the R-MAPP (Remote-Malnutrition APP). MATERIALS AND METHODS: A cross-sectional study of 337 consecutive outpatients ≥65 years who attended the Central Emergency COVID-19 Hospital of Castilla y Leon was conducted. In all patients, the protocol of R-MAPP (Malnutrition Universal Screening Tool [MUST] and Simple Questionnaire to Rapidly Diagnose Sarcopenia [SARC-F]) was realized. RESULTS: The mean age was 86.1 ± 8.7 years, with a sex distribution of 167 males (49.5%) and 170 females (51.5%). According to the MUST test, patients with 0 points have a low nutritional risk (n = 50, 14.8%), 1 point a medium nutritional risk (n = 19, 5.6%), and 2 or more points a high nutritional risk (n = 268, 79.6%). The SARC-F questionnaire generates patients with 4 or more points as predictive of sarcopenia (n = 304, 80.2%) and <4 points without prediction of sarcopenia (n = 33, 9.8%). Global mortality was 24.03% (n = 81). The mortality rate was related to the pathological SARC-F score ≥4 (27.1% vs. 3.1%; p = 0.01) and MUST score ≥2 (26.7% vs. 16.4%; p = 0.04). In the logistic regression analysis, only the SARC-F score ≥4 remained as an independent variable related to mortality; odds ratio was 8.34 (95% CI: 1.1-63.8; p = 0.04), adjusted for age, sex, albumin levels, and MUST test. CONCLUSIONS: During COVID-19 infection, hospitalized patients at risk of sarcopenia have a high risk of mortality and have a poor nutritional status.

Omentin-1 Changes following Biliopancreatic Diversion and Relationship with Cardiovascular Risk Factors.

INTRODUCTION: Omentin-1 might play a role in the pathogenesis of insulin resistance and obesity. The aim of the present study was to evaluate the influence of weight loss after biliopancreatic diversion on serum omentin-1 concentrations. Material and Methods A Caucasian population of 24 morbid obese patients was analyzed before and after 12 months of a biliopancreatic diversion surgery. Biochemical and anthropometric evaluation were realized at basal visit and at 12 months. Body weight, fat mass, waist circumferences, blood pressure, fasting blood glucose, fasting insulin, insulin resistance (HOMA-IR), lipid concentrations and omentin-1 were measured. RESULTS: After bariatric surgery and in both gender groups (males vs. females); BMI, weight, fat mass, waist circumference, blood pressure, glucose , total cholesterol, LDL cholesterol, triglycerides, HOMA-IR and fasting insulin decreased in a statistical manner from basal values. Omentin-1 levels increased after bariatric surgery and in both gender the improvement was similar (males vs. females); (delta: -87.1 ± 19.0 ng/dL; p = 0.02 vs. -93.8 ± 28.1 ng/dL; p = 0.03). In the multiple regression analysis adjusted by age and sex; BMI kg/m2 (Beta -0.32: 95% CI -3.98 to -0.12) and insulin UI/L (Beta -0.41: 95% CI -8.38 to -0.16) remained in the model with basal omentin-1 levels as dependent variable. The regression model with post-surgery omentin-1 levels as dependent variable showed as independent variables BMI kg/m2 (Beta -0.13: 95% CI -7.69 to -0.09) and insulin UI/L (Beta -0.24: 95% CI -5.69 to -0.08), too. CONCLUSION: This study showed a significant increase in omentin-1 levels after weight loss secondary biliopancreatic diversion surgery. A weak negative correlation with BMI and basal insulin levels was detected.

Impact of the rs822393 Variant on Adiponectin Levels and Metabolic Parameters after Weight Loss Secondary to a High-Fat Hypocaloric Diet with Mediterranean Pattern.

INTRODUCTION: The effects of the rs822393 variant of ADIPOQ gene on metabolic parameters such as insulin resistance and adiponectin levels following weight loss through dietary intervention are still uncertain. The aim of this study was to evaluate the role of rs822393 of ADIPOQ gene on adiponectin levels and metabolic parameters after weight loss with a high-fat hypocaloric diet with Mediterranean pattern during 12 weeks. METHODS: A population of 283 patients with obesity was allocated to a dietary intervention trial with a high-fat hypocaloric diet during 12 weeks. Adiposity and biochemical parameters were determined. rs822393 was assessed with a dominant model analysis (CC vs. CT + TT). RESULTS: These patients had three different genotypes: CC (59.0%), CT (33.6%), and TT (7.4%). The allelic frequencies for C and T were 0.89 and 0.20, respectively. Basal and post-intervention HDL cholesterol, adiponectin levels, and adiponectin/leptin ratio were lower in T-allele than non-T-allele carriers. After dietary intervention, BMI, weight, fat mass, waist circumference, systolic blood pressure, insulin, HOMA-IR, leptin, total cholesterol, and LDL cholesterol levels improved significantly in both genotype groups. Moreover, HDL cholesterol (CC vs. CT + TT) (delta: 8.9 ± 1.1 mg/dL vs. 1.7 ± 0.8 mg/dL; p = 0.02), serum adiponectin in non-T-allele carriers (43.1 ± 5.9 ng/dL vs. 2.8 ± 3 0.0 ng/dL; p = 0.01), and adiponectin/leptin ratio (1.37 ± 0.1 units vs. 0.17 ± 0.08 units; p = 0.02) improved only in non-T-allele carriers after weight loss. CONCLUSION: Individuals with obesity and without the T allele of rs822393 experienced improvements in adiponectin levels, adiponectin/leptin ratio, and HDL cholesterol levels after following a high-fat hypocaloric diet with a Mediterranean pattern.

Role of rs2282679 in 25-hydroxyvitamin D levels and insulin resistance after a sleeve gastrectomy.

BACKGROUND & AIMS: Some studies have reported links between 25-hydroxyvitamin D levels and the presence of obesity and some genetic variants. The aim of our design was to evaluate the effects of rs2282679 genetic variant of CG gene on 25-hydroxyvitamin D levels, weight loss and metabolic parameters after a robotic sleeve gastrectomy in premenopausal females with obesity. METHODS: 76 participants were enrolled. 25-hydroxyvitamin D levels, biochemical evaluation and anthropometric parameters were registered before surgery and after 3, 6 and 12 months follow up. Genotype of rs2282679 CG gene was evaluated. RESULTS: The improvements in anthropometric parameters, blood pressure and lipid profile were similar in both genotypes (TT vs TG + GG). Basal insulin levels and HOMA-IR were greater in G allele carriers than non-carriers (Delta: 6.7 ± 1.2 mUI/L; p = 0.01) and (Delta: 1.3 ± 0.1 units; p = 0.02). 25-hydroxyvitamin D levels were lower in G allele carriers than non-carriers (Delta: 8.1 ± 1.1 ng/dl; p = 0.03). The levels of insulin and HOMA-IR remained greater in G allele carriers than non-carriers throughout all the visits. The levels of 25-hydroxyvitamin D remained lower in G allele carriers than non-G allele. The average level of 25-hydroxyvitamin D at 12 months in non-G allele carriers were above 30 ng/dl (36.0 ± 3.1 ng/dl) and the level in G allele carriers were below (24.9 ± 4.9 ng/dl). CONCLUSIONS: rs 2282679 (GC) was related with low 25 hydroxyvitamin D levels and insulin resistance. In addition, the presence of G allele produced a decrease in the improvement of 25-hydroxyvitamin D levels and insulin resistance after weight loss during 12 months.

Weight-adjusted waist index predicts metabolic syndrome in Caucasian patients with obesity.

BACKGROUND AND AIMS: the usefulness of the weight-adjusted waist index (WWI) among persons with metabolic syndrome (MS) has not been previously evaluated. The objective of this study was to evaluate the ability of WWI to predict MS in a Caucasian population with obesity. METHODS: we conducted a cross sectional study in 2162 Caucasian patients with obesity. Anthropometric data (weight, height, body mass index [BMI], waist circumference, [WWI]), bioimpedanciometer parameters (total fat mass [FM], skeletal muscle mass [SMM] and skeletal muscle mass index [SMMi]), blood pressure, presence of MS and biochemical parameters were recorded and compared by tertiles of WWI. RESULTS: a total of 1,176 subjects had MS (54.4 %) and 986 did not show MS (45.6 %). Compared with the lowest WWI category Q1 (< 11.24 cm/√kg), the prevalence of MS increased in the logistic regression model adjusted by sex and age in the Q3 group (OR = 2.53, 95 % CI = 1.71-3.23; p = 0.001). In addition, the prevalence of MS was higher in the Q3 group than in Q2 (OR = 1.65, 95 % CI = 1.25-2.17; p = 0.005). Finally, the prevalence of MS in Q2 was higher than in the Q1 group (OR = 1.21, 95 % CI = 1.06-3.11; p = 0.01). The area under the curve (AUC) to assess the ability of WWI to identify MS showed values of 0.811 (0.687-0.871; p = 0.001). The cut-off point according to the Youden index was 11.59, with sensitivity and specificity of 70 % and 93.4 %, respectively. CONCLUSION: we described a good accuracy of WWI to identify MS an independent association between WWI in Caucasian patients with obesity.

Evaluation of Muscle Mass and Malnutrition in Patients with Colorectal Cancer Using the Global Leadership Initiative on Malnutrition Criteria and Comparing Bioelectrical Impedance Analysis and Computed Tomography Measurements.

OBJECTIVES: The aim of this investigation was to evaluate the discrepancies between bioelectrical impedance analysis (BIA) and computed tomography (CT) in assessing skeletal muscle mass and identifying low muscle mass in patients with colorectal cancer. METHODS: This study recruited 137 patients with colorectal cancer from February 2028 to December 2023. CT scans were analyzed at the Lumbar 3 vertebral level to determine the area of skeletal muscle, which was then utilized to estimate whole-body skeletal muscle mass. [BIA] was also employed to measure skeletal muscle. Both skeletal muscle mass values [kg] were divided by height2 [m2] to calculate the skeletal muscle index [SMI, kg/m2], denoted as SMI-CT and SMI-BIA, respectively. RESULTS: The median age was 69.8 + 9.5 years, with the sex ratio being 88/49 [male/female]. Whereas more than one-third of the patients were classified as malnourished based on the Global Leadership Initiative on Malnutrition GLIM-CT criteria using L3-SMI [n = 36.5%], fewer patients were classified as malnourished based on GLIM-BIA using SMI-BIA [n = 19.0%]. According to the CT analysis [low SMI-L3], 52 [38.0%] patients were diagnosed as having poor muscle mass, whereas only 18 [13.1%] patients were identified as having low muscle mass using BIA [low SMIBIA]. The measured SMI showed a positive association with SMI-CT in all patients [r = 0.63, p < 0.001]. Using Bland-Altman evaluation, a significant mean bias of 0.45 + 1.41 kg/m2 [95% CI 0.21-0.70; p < 0.001] between SMI-BIA and SMI-CT was reported. Receiver operating characteristic (ROC) curves were generated to detect poor muscle mass using SMI-BIA with CT as the gold standard. The area under the curve (AUC) for SMI-BIA in identifying poor muscle mass was 0.714 (95% CI: 0.624-0.824), with a good cut-off value of 8.1 kg/m2, yielding a sensitivity of 68.3% and a specificity of 66.9%. CONCLUSIONS: BIA generally overestimates skeletal muscle mass in colorectal cancer patients when contrasted to CT. As a result, BIA may underestimate the prevalence of poor muscle mass and malnutrition according to the GLIM criteria in this patient population.

Validation of an Artificial Intelligence-Based Ultrasound Imaging System for Quantifying Muscle Architecture Parameters of the Rectus Femoris in Disease-Related Malnutrition (DRM).

(1) Background: The aim was to validate an AI-based system compared to the classic method of reading ultrasound images of the rectus femur (RF) muscle in a real cohort of patients with disease-related malnutrition. (2) Methods: One hundred adult patients with DRM aged 18 to 85 years were enrolled. The risk of DRM was assessed by the Global Leadership Initiative on Malnutrition (GLIM). The variation, reproducibility, and reliability of measurements for the RF subcutaneous fat thickness (SFT), muscle thickness (MT), and cross-sectional area (CSA), were measured conventionally with the incorporated tools of a portable ultrasound imaging device (method A) and compared with the automated quantification of the ultrasound imaging system (method B). (3) Results: Measurements obtained using method A (i.e., conventionally) and method B (i.e., raw images analyzed by AI), showed similar values with no significant differences in absolute values and coefficients of variation, 58.39-57.68% for SFT, 30.50-28.36% for MT, and 36.50-36.91% for CSA, respectively. The Intraclass Correlation Coefficient (ICC) for reliability and consistency analysis between methods A and B showed correlations of 0.912 and 95% CI [0.872-0.940] for SFT, 0.960 and 95% CI [0.941-0.973] for MT, and 0.995 and 95% CI [0.993-0.997] for CSA; the Bland-Altman Analysis shows that the spread of points is quite uniform around the bias lines with no evidence of strong bias for any variable. (4) Conclusions: The study demonstrated the consistency and reliability of this new automatic system based on machine learning and AI for the quantification of ultrasound imaging of the muscle architecture parameters of the rectus femoris muscle compared with the conventional method of measurement.

[Medical nutrition therapy in amyotrophic lateral sclerosis - Do we act or react? A case report and multidisciplinary review]. / Tratamiento médico nutricional en la esclerosis lateral amiotrófica: ¿Actuamos o reaccionamos? Un caso clínico y revisión multidisciplinar.

Introduction: Background: amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with a progressive course. The current prevalence is between 3 and 6 cases/100,000. Malnutrition is closely related to patient prognosis in ALS. The implications of this conditions have been that we should recommend patient care in a multidisciplinary unit. Case report: the case presented shows the evolution of a patient with ALS. The patient was referred to different clinical departments after neurological evaluation and her nutritional, functional and respiratory status were assessed. There was no nutritional deterioration at diagnosis; however, intake was below energy-protein requirements. The clinical evolution of the patient showed a decrease in muscle mass with preservation of weight and fat mass. "Aggressive" measures to control nutritional status such as gastrostomy were rejected in the initial stages of the disease, but had to be carried out after development of dysphagia and associated malnutrition. This situation of progressive morphofunctional deterioration and the development of disease-related complications made essential the participation of different health services and professionals in its control. Dicussion: the management of ALS in a multidisciplinary manner allows to improve the course of the disease and the quality of life of both the patients and their families. Patient follow-up is based on the adjustment and management of complications. The basis of the relationship with these patients includes maintaining an adequate communication with them and their families, and ensuring joint decision-making about their condition.

Introducción: Introducción: la esclerosis lateral amiotrófica (ELA) es una enfermedad neurodegenerativa cuya prevalencia en la actualidad está entre 3 y 6 casos/100.000. La desnutrición está íntimamente relacionada con el pronóstico en el paciente con ELA. Las implicaciones de esta enfermedad hacen que se deba recomendar al paciente la asistencia en una unidad multidisciplinar. Caso clínico: el caso presentado muestra la evolución de una paciente con esclerosis lateral amiotrófica desde el diagnóstico. Tras la valoración por parte de Neurología, se remitió a la paciente a los distintos servicios de seguimiento (Endocrinología, Rehabilitación, Neumología). No se observó deterioro nutricional al diagnóstico; no obstante, la ingesta se encontraba por debajo de los requerimientos. En la progresión de la enfermedad se observó un deterioro de la masa muscular con estabilidad ponderal y de la masa grasa, pero la paciente desarrolló disfagia, síntoma típico de la enfermedad. El planteamiento de medidas "agresivas" para controlar el estado nutricional, como la gastrostomía, fue rechazado al inicio, pero hubo que realizarlas tras la progresión de la disfagia y la desnutrición asociada. Esta situación de deterioro morfofuncional y el desarrollo de complicaciones plantearon la participación de distintos profesionales sanitarios en su control. Discusión: el manejo de la ELA de manera multidisciplinar permite mejorar la evolución de la enfermedad y la calidad de vida del paciente y sus familiares. El seguimiento se basa en el ajuste y el manejo de las complicaciones, en mantener una adecuada comunicación con el paciente y sus familiares, y en tomar de manera conjunta las decisiones sobre su patología.

Effectiveness of High-Protein Energy-Dense Oral Supplements on Patients with Malnutrition Using Morphofunctional Assessment with AI-Assisted Muscle Ultrasonography: A Real-World One-Arm Study.

Background: User-friendly tools for assessing nutrition status and interventions in malnourished patients are crucial. This study evaluated the effectiveness of a personalised nutrition intervention using a novel oral nutritional supplement and AI-supported morphofunctional assessment to monitor clinical outcomes in patients with disease-related malnutrition (DRM). Methods: This prospective observational study involved patients receiving concentrated high-protein, high-calorie ONS (cHPHC-ONS), per usual clinical practice. Comprehensive assessments were performed at baseline (B0) and three months (M3) post-intervention. Results: 65 patients participated in the study. Significant decreases were observed in the percentage weight loss from B0 (-6.75 ± 7.5%) to M3 (0.5 ± 3.48%) (p < 0.01), in the prevalence of malnutrition (B0: 93.4%; M3: 78.9%; p < 0.01), severe malnutrition (B0: 60.7%; M3: 40.3%; p < 0.01), and sarcopenia (B0: 19.4%; M3: 15.5%; p < 0.04). Muscle area increased (p = 0.03), and there were changes in the echogenicity of the rectus femoris muscle (p = 0.03) from B0 to M3. In patients aged ≥60, an increase in muscle thickness (p = 0.04), pennation angle (p = 0.02), and handgrip strength (p = 0.04) was observed. There was a significant reduction in the prevalence of malnutrition (B0: 93.4%; M3: 78.9%; p < 0.01) and severe malnutrition (B0: 60.7%; M3: 40.3%; p < 0.01). Conclusions: In patients with DRM, a personalised intervention with cHPHC-ONS significantly reduces the prevalence of malnutrition, severe malnutrition, and sarcopenia and improves muscle mass and function.

Relationship of circulating resistin levels with muscle mass determined by bioelectrical impedance in females with obesity.

INTRODUCTION: Serum resistin levels have been associated with obesity, visceral fat, and insulin resistance. Its relationship with muscle mass has been less evaluated. OBJECTIVES: to evaluate the relationship between muscle mass determined by electrical bioimpedance and circulating resistin levels in obese women over 60 years of age. METHODS: We conducted a cross-sectional study in 313 obese women. Anthropometric data (weight, height, body mass index (BMI) and waist circumference), BIA parameters (total fat mass (TFM), fat-free mass (FFM), fat-free mass index (FFMI)), skeletal muscle mass (SMM) and skeletal muscle mass index (SMI)), blood pressure and laboratory tests were recorded. RESULTS: Patients were divided into two different groups according to the mean value of SMI (11.93 kg/m2): low SMI versus high SMI. In the low SMI group, the resistin levels were higher than the resistin levels in the high SMI group (delta value: 2.8 + 0.3 ng/dl:p = 0.01). Serum resistin levels are inversely correlated with FFM, FFMI, SMM, and SMI. This adipokine shows a positive correlation with insulin, HOMA-IR and PCR levels. In the model with SMI as the dependent variable, resistin levels explained 12% of the variability in muscle mass (Beta -0.38, 95% CI -0.91 to -0.11). CONCLUSIONS: Serum resistin levels are associated with low skeletal muscle mass in obese women over 60 years of age.

Prevalence of sarcopenia in patients older than 75 years admitted for hip fracture.

BACKGROUND: Hip fracture in the population aged 75 years and older is one of the most disabling pathologies. Likewise, disease related malnutrition (DRM) and sarcopenia are two frequent diagnoses in this age group, whose prevalence may be increased in patients with hip fracture. AIMS: To determine the prevalence of malnutrition and/or sarcopenia in patients admitted for hip fracture and evaluate the existence of malnutrition related to disease and sarcopenia, and the differences between the sarcopenic and non-sarcopenic group. METHODS: 186 patients aged 75 years or over, hospitalised for hip fracture from March 2018 to June 2019 were included. Demographic, nutritional and biochemical variables were collected. Nutritional screening was carried out with the Mini-Nutritional Assessment (MNA), the presence of DRM was established with The Global Leadership Initiative on Malnutrition (GLIM) criteria. For sarcopenia screening, the Strength, Assistance with walking, Rising from a chair, Climbing stairs and Falls (SARC-F) was used and the diagnosis of sarcopenia was made using the criteria from the European Working Group on Sarcopenia in Older People (EWGSOP) reviewed in 2019 (EWGSOP2). Muscle strength was determined by hand-grip strength, body composition by measurement of bioelectrical impedance. RESULTS: The mean age was 86.2 years, most of the patients were women (81.7%). 37.1% of patients were at nutritional risk (MNA 17-23.5) and 16.7% were malnourished (MNA < 17). 72.4% of women and 79.4% of men, were diagnosed with DRM. 77.6% of the women and 73.5% of the men had low muscle strength. The appendicular muscle mass index was below the cut-off points for sarcopenia in 72.4% of the women and 79.4% of the men. Patients with sarcopenia had a lower body mass index, older age, poorer previous functional status and higher disease burden. The relationship between weight loss and hand grip strength (HGS) was significant (p = 0.007). CONCLUSIONS: 53.8% of patients admitted for hip fracture present malnutrition or are at risk after screening with MNA. Sarcopenia and DRM affects at least three out of four patients older than 75 years admitted for hip fracture. Older age, worse functional status, lower body mass index and high number of comorbidities, are associated with these two entities. There is a relationship between DRM and sarcopenia.

[Decreased muscle mass in type-2 diabetes. A hidden comorbidity to consider]. / La masa muscular disminuida en la diabetes de tipo 2. Una comorbilidad oculta que debemos tener en cuenta.

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.

Nutritional Ultrasonography, a Method to Evaluate Muscle Mass and Quality in Morphofunctional Assessment of Disease Related Malnutrition.

Nutritional ultrasonography is an emerging technique for measuring muscle mass and quality. The study aimed to evaluate the relationship between the parameters of body mass and quality of ultrasonography with other parameters of morphofunctional assessment in patients with disease-related malnutrition (DRM). METHODS: A cross-sectional study was developed on 144 patients diagnosed with DRM according to the Global Leadership Initiative on Malnutrition (GLIM) criteria. Morphofunctional evaluation was assessed with anthropometric variables, handgrip strength and bioelectrical impedanciometry (BIA). Nutritional ultrasonography of quadriceps rectus femoris (QRF) was made (muscle mass (Muscle Area of Rectus Femoris index (MARFI)), Y axis and muscle quality (X-Y index and echogenicity). RESULTS: The mean age of patients was 61.4 (17.34) years. The prevalence of sarcopenia in the sample was 33.3%. Patients with sarcopenia (S) had lower values of MARFI [(S: 1.09 (0.39) cm2/m2; NoS: 1.27 (0.45); p = 0.02), Y axis (S: 0.88 (0.27); NoS: 1.19 (0.60); p < 0.01) and X-Y index (S: 1.52 (0.61); NoS: 1.30 (0.53); p < 0.01)]. There was a correlation between BIA parameters (phase angle) and muscle mass ultrasonographic variables (MARFI) (r = 0.35; p < 0.01); there was an inverse correlation between muscle quality ultrasonographic variables (echogenicity) and handgrip strength (r = -0.36; p < 0.01). In the multivariate analysis adjusted by age, the highest quartile of the X-Y index had more risk of death OR: 4.54 CI95% (1.11-18.47). CONCLUSIONS: In patients with DRM and sarcopenia, standardized muscle mass and muscle quality parameters determined by ultrasonography of QRF are worse than in patients without sarcopenia. Muscle quality parameters had an inverse correlation with electric parameters from BIA and muscle strength. The highest quartile of the X-Y index determined by ultrasonography was associated with increased mortality risk.

Metabolic control and satisfaction in a diabetes education programme in flash glucose monitoring through telemedicine in type 1 diabetes.

OBJECTIVE: To evaluate metabolic control and satisfaction with a telemedicine diabetes education programme for the initiation of flash glucose monitoring (FGM) in type 1 diabetes. MATERIAL AND METHODS: Prospective study in 48 patients (52.1% women, 22.9% on insulin pump) who started FGM. They were analysed at baseline and 3 months after the beginning of the FGM. The results were compared with an on-site learning cohort matched by age, sex and HbA1c. RESULTS: At the beginning and 3 months after the MFG, HbA1c improvement was observed (7.9±1.4 vs 7.3±1.1%), p<0.01; with a decrease in time below range - TBR - (4.7±4.9 vs 3.5±3.5%), p<0.05 and number of hypoglycaemic events (9.4±8.7 vs 6.9±5.7/15 days), p<0.05, associated with a worsening in time above range - TAR - (33.5±19.9 vs 37.0±20.9%), p<0.05. No significant differences were observed in the TIR 70-180mg/dl (61.7±18.6 vs 59.4±20.0%), glycemic variability or the use of FGM. Patient satisfaction with telemedicine training was 4.8±0.3 out of 5. No significant differences were observed in the follow-up, either in HbA1c or other glucometer parameters between on-site and online training. In a multivariate analysis adopting the HbA1c at follow-up as the dependent variable, only the TIR (ß=-0.034; p<0.001) and the initial HbA1c (ß=0.303; p<0.001) maintained statistical significance, unrelated to the on-site or online training (ß=0.136; p=ns). CONCLUSIONS: A telemedicine programme is an adequate tool for training in FGM, with results similar to on-site training, and it was associated with a high degree of satisfaction.

[Morphofunctional assessment of nutritional status and connection with Primary Care]. / Valoración morfofuncional del estado nutricional y vinculación con Atención Primaria.

Introduction: Appropriate nutritional assessment and interventions are associated with improved prognosis for hospitalized patients and reduced healthcare expenditure. After discharge, good communication between endocrinology specialists and primary care physicians is necessary to ensure continuity of care. Regarding the primary care provider and the specialist in clinical nutrition, this article summarizes traditional and novel tools for the morphofunctional assessment of nutritional status, with an emphasis on those that can be used in primary care. We also give some key points to improve relationships and communication between specialists in nutrition and primary care physicians.

Evolution of suppressing TSH therapy at diagnosis and in the long-term follow-up in a cohort of differentiated thyroid cancer.

INTRODUCTION: To evaluate the adequacy of TSH suppression therapy (TSHst) at the first disease assessment and the last follow-up visit. METHODS: Retrospective observational study of those patients under follow-up of DTC in a reference hospital. RESULTS: 216 patients (79.2% women) were evaluated, with a mean age 59.0 ±â€¯13.1 years-old and a mean follow-up of 6.9 ±â€¯4.3 years. 88.4% were papillary carcinomas. At diagnosis, 69.2% had a low risk of recurrence (RR) compared to 13.6% with a high RR. Dynamic risk stratification (DRS) classified patients at first disease assessment and the last visit as excellent response (ER) in 60.0% and 70.7%, respectively. Those patients with ER in the first and last follow-up control maintained TSHst in 30.7% and 16.3% of the cases, respectively (p < 0.001). The factors associated with maintaining TSHst at the last control were younger age, higher RR at diagnosis, DRE at follow-up, presence of multifocality and histological vascular invasion (p < 0.05). In a logistic regression analysis adopting tsTSH at follow-up as the dependent variable, exclusively age (ß = -0.062; p < 0.001), RR at diagnosis (ß = 1.074; p < 0.05) and EDR during follow-up (ß = 1.237; p < 0.05) maintained statistical significance. CONCLUSIONS: Despite the current recommendations, 30.7% of patients with low RR and initial ER are under TSHst. This percentage reduced to 16.3% in those patients with ER after a mean follow-up of 6.9 years. Age, baseline RR, and DRE during follow-up were associated to maintaining tsTSH.

[Hyponatremia among patients with total enteral tube feeding: prevalence and associated clinical factors]. / Prevalencia y factores asociados a la hiponatremia en pacientes con nutrición enteral.

Introduction: Introduction: hyponatremia is the most frequent disturbance in hospitalized patients. This situation may influence the therapeutic approach in patients with total enteral tube feeding (TEN). Objective: to study the prevalence of hyponatremia and the clinical factors that are associated with increased risk in a population with TEN. Methods: a retrospective study from January 2014 to January 2020; 1,651 non-critically ill patients receiving TEN were included who were assessed by the Department of Endocrinology and Nutrition. Data collected included sex, age, body mass index (BMI) (kg/m2), and nutritional status by Mini Nutritional Assessment (MNA); main disease diagnosis and development of hyponatremia at onset or during TEN were also included. Results: in all, 53.9 % of the total sample were males aged 76.8 [65.7-85.3] years. Neurological pathology was the most frequent primary diagnosis on admission (37.3 %). We found hyponatremia in 26.1 % -11.0 % at onset and 16.7 % during TEN-. Hyponatremia was more frequent in patients with digestive disease (28.7 %) and infectious disease (27.65 %). According to the MNA questionnaire 41.1 % were malnourished and nutritional status was worse in patients with hyponatremia (76.3 % vs. 55.8 %; p < 0.001). By multivariate analysis, malnutrition was only associated with hyponatremia status; OR, 2.86 [95 % CI: 1.5-4.88]. Conclusions: in this study, hyponatremia was detected in a third of patients. This was up to two more times as common in malnourished patients; however, age, sex, BMI, and baseline pathology were not related.

Introducción: Introducción: la hiponatremia es el trastorno electrolítico más frecuente a nivel hospitalario. En pacientes con nutrición enteral (NE) puede influir en el abordaje terapéutico, así como en la selección del preparado nutricional. Objetivos: describir la prevalencia de la hiponatremia en pacientes con NE y factores asociados. Métodos: estudio retrospectivo de 1651 pacientes no críticos con NE, valorados por el Servicio de Endocrinología y Nutrición desde enero de 2014 hasta enero de 2020. Se recogieron la edad, el sexo, el índice de masa corporal (IMC) (kg/m2), el estado nutricional mediante el cuestionario Mini Nutritional Assessment (MNA), el diagnóstico principal y la presencia de hiponatremia al inicio y durante la NE. Resultados: del total, el 53,9 % fueron hombres, con una mediana de edad de 76,8 [65,7-85,3] años. El diagnóstico principal más frecuente fue la patología neurológica (37,3 %). El 26,1 % de los pacientes presentaron hiponatremia: un 11,0 % al inicio de la NE y el 16,7% durante su administración. La hiponatremia fue más frecuente en aquellos con patología digestiva (28,7 %) e infecciosa (27,65 %). Según el MNA, hasta el 41,1 % presentaron desnutrición y la frecuencia de esta fue estadísticamente superior en los pacientes con que en aquellos sin hiponatremia (76,3 % vs. 55,8 %; p < 0,001). En el análisis multivariante, únicamente la desnutrición se asoció de manera significativa con la presencia de hiponatremia, con una OR de 2,86 [IC 95 %: 1,5-4,88]. Conclusiones: la hiponatremia se detectó en un tercio de los pacientes con NE. Su presencia fue hasta 2 veces más frecuente en los pacientes desnutridos, independientemente de la edad, el sexo, el IMC y la patología basal.

Impact of flash glucose monitoring on quality of life and glycaemic control parameters in adults with type 1 diabetes mellitus⋆.

INTRODUCTION: Flash glucose monitoring (FGM) improves some glycaemic control variables and quality of life parameters. OBJECTIVE: Our aim was to evaluate the quality of life and glycaemic control parameters after initiating FGM in patients with type 1 diabetes (DM1) in clinical practice. MATERIAL AND METHODS: A prospective observational study in DM1 patients that started using FGM between June 2019 and April 2020. We analysed their scores on the Diabetes Quality of Life (DQOL) questionnaire, Diabetes Distress Scale (DDS), Diabetes Treatment Satisfaction Questionnaire (DTSQ) and glycaemic control parameters at baseline and 3 months after the FGM onset. RESULTS: We recruited 114 patients, 56% male, mean age 37.2 (standard deviation, SD 12.4), with 18.7 (SD 11.5) years of DM1, 24.6% of which used continuous subcutaneous insulin infusion. Differences were observed (baseline vs. 3 months) in the DTSQ score (22 [15.5-27] vs. 25 [22-28], P < 0.001) and in the DQOL score (88 [74-104] vs. 84 [70-101], P = 0.017) but not in the DDS score. HbA1c was 7.8% (SD 1.3) vs. 7.4% (SD 1.1) (P < 0.001), without improvement in other glycaemic control variables, except for the mean number of hypoglycaemic events/14 days: 14 (SD 9) at baseline vs. 11.5 (SD 7) at 3 months (P < 0.001). CONCLUSIONS: The initiation of FGM, combined with a structured educational programme, was associated with improvement in quality of life and patient satisfaction in DM1 patients. An improvement in HbA1c and a reduction in the number of hypoglycaemia events was observed, but not in the rest of glycaemic control parameters.
