Introducción: la pandemia originada en 2019 por el SARS-CoV-2 supuso un cambio en los hábitos de alimentación y ejercicio físico por causa de las medidas de confinamiento domiciliario. El seguimiento de pacientes en tratamiento de pérdida de peso mediante una consulta telemática podría ser una herramienta útil para prevenir el fracaso terapéutico. Objetivo: describir la evolución de los parámetros antropométricos de pacientes en seguimiento para pérdida de peso mediante una consulta telemática. Métodos: estudio prospectivo en 2 tiempos (antes y después del confinamiento) de una intervención telemática sobre pacientes adultos en seguimiento habitual por sobrepeso y obesidad. Se analizaron las variables demográficas y los parámetros de composición corporal mediante bioimpendancia. Además se analizaron las diferencias en cuanto a presencia de tratamiento farmacológico adyuvante del tipo de los análogos de la hormona GLP1 (liraglutida o semaglutida). Las variables se estudiaron mediante la prueba de Wilcoxon, la U de Mann-Whitney y la correlación de Spearman. Se consideró la significación si p ¿ 0,05. Resultados: se incluyeron 97 pacientes. Antes del confinamiento, el 42,3 % presentaban sobrepeso (IMC < 30 kg/m2), el 36,1 % tenían obesidad de grado I (IMC = 30-34,9 kg/m2), el 16,4 % la tenían de grado II (IMC = 35-39,9 kg/m2) y el 5,2 % tenían un IMC > 40 kg/m2. El 30,9 % presentaban prediabetes y el 9,3 % tenían diabetes de tipo 2. Entre ambas visitas presenciales, el 81,4 % de los pacientes perdieron un 4,2 ± 3,4 % del peso, con una disminución media significativa de la masa grasa de 3,16 ± 4,4 kg. El grupo en tratamiento farmacológico con análogos de la hormona GLP-1 presentó una pérdida de masa grasa media significativamente superior sin pérdida de masa muscular esquelética significativa. Conclusiones: el seguimiento telemático parece una herramienta útil para prevenir la ganancia de peso en los pacientes con restricción de la movilidad. Una intervención telemática que contenga consejo dietético y ejercicio como refuerzo de la dieta hipocalórica ayuda a conseguir perder peso, predominando el componente graso. La presencia de un tratamiento farmacológico con análogos de la hormona GLP-1 parece ayudar significativamente al mantenimiento de la masa muscular esquelética durante la pérdida de peso.

Featured Application The data from the present study indicate that nutritionists and other healthcare professionals should monitor the quality of life and diet quality of children with celiac disease, especially from the first year of treatment with a gluten-free diet. Maintaining a strict gluten-free diet (GFD) may affect the quality of life of children with celiac disease (CD) and promote a less healthy diet by substituting gluten-containing foods with ultra-processed foods. We aimed to assess the influences of the GFD and ultra-processed food consumption on parents' perception of the quality of life of children with CD. Fifty-eight children (mean age 8.6 +/- 4.1 years) were included. The participants were divided into groups based on the time following a GFD: <6 months (n = 18) versus >= 12 months (n = 37). Their dietary consumption was assessed through a three-day food record. The 20-item Celiac Disease Quality Of Life survey (CD-QOL), which contains four subscales (limitations, dysphoria, health concerns, and inadequate treatment) was used to assess the quality of life. The children who followed a GFD for >= 12 months presented poorer scores in the limitations subscale than those who followed a GFD for <6 months (p = 0.010). The mean % of the energy intake from ultra-processed foods was 47.3 +/- 13.5. Children with CD consuming more than 50% of their total energy from ultra-processed foods showed poorer scores for the limitation and inadequate treatment (both, p = 0.019) subscales than their counterparts. According to parents' perceptions, those children who consumed more than 50% of their energy through ultra-processed foods had more limitations, and their treatment was perceived as less effective.

Objective: A differential diagnosis of thyrotoxicosis is crucial as the treatment of the main causes of this condition can vary significantly. Recently published diagnostic guidelines on thyrotoxicosis embrace the presence of thyrotropin receptor (TSH-R) antibodies (TRAb) as the primary and most important diagnostic step. The application of diagnostic algorithms to aid in the treatment of hyperthyroidism supports using thyroid radionuclide scintigraphy (TRSt) in baffling clinical scenarios, when TRAb are absent or when third-generation TRAb are not available. First-generation TRAb measurement may have limitations. Consequently, patients with thyrotoxicosis and first-generation TRAb results may be misdiagnosed and consequently improperly treated. Our purpose was to compare first-generation TRAb values to TRSt in the differential diagnosis of hyperthyroidism. Methods: We conducted a retrospective study of 201 untreated outpatients with overt or subclinical hyperthyroidism on whom first-generation TRAb and TRSt had been performed at the time of diagnosis. Histological specimens were analysed in patients who had previously undergone thyroid surgery at our centre. SPSS 20.0 was used in statistical analysis. Results: Seventy-three out of 201 (36.3%) patients had positive TRAb. A diffuse uptake was present in 83.5% (61/73), whereas 13.7% (10/73) had a heterogeneous uptake and 2.7% (2/73) had an absent uptake. Thirty out of 91 (33%) patients with diffuse uptake were negative for positive TRAb and were diagnosed with Graves' disease. Analysis of 37 histological specimens indicated that TRSt had greater accuracy (81% vs 75.7%) and specificity (79.2% vs 57.1%) when compared to TRAb in the differential diagnosis of thyrotoxicosis. However, TRSt sensitivity was inferior to TRAb (84.6% vs 92.3%). Conclusions: Our study endorses that initial differential diagnosis of thyrotoxicosis should not be based solely on first-generation TRAb as this approach may leave nearly 20% of the patients misdiagnosed and, consequently, improperly treated. Our results underscore that thyroid scintigraphy should also be performed when only first-generation TRAb assays are available during the initial differential diagnosis of thyrotoxicosis.

Bone mineral density using dual-energy X-ray absorptiometry is the gold standard for the assessment of bone and an important predictor of fracture risk. However, most fragility fractures occur in people without densitometric osteoporosis, especially in endocrinological diseases. Fracture risk estimation tools such as FRAX have improved diagnostic sensitivity but do not include additional skeletal features. Bone microarchitecture research represents an improvement in the treatment of these patients. In this document members of the Mineral and Bone Metabolism Working Group of the Spanish Society of Endocrinology and Nutrition review new advances in dual -energy X-ray absorptiometry and other complex techniques for the study of bone microarchitecture as well as the available data on type 2 diabetes and parathyroid pathology.

Objective: Glucagon-like peptide (GLP)-1 has been proposed as a key candidate in glucose improvements after bariatric surgery. Our aim was to explore the role of GLP-1 in surgically-induced type 2 diabetes (T2D) improvement and its capacity to regulate human adipocyte inflammation. Methods: Basal circulating concentrations of GLP-1 as well as during an oral glucose tolerance test (OGTT) were measured in lean and obese volunteers with and without T2D (n = 93). In addition, GLP-1 levels were determined before and after weight loss achieved by Roux-en-Y gastric bypass (RYGB) (n = 77). The impact of GLP-1 on inflammation signalling pathways was also evaluated. Results: We show that the reduced (p < 0.05) circulating levels of GLP-1 in obese T2D patients increased (p < 0.05) after RYGB. The area under the curve was significantly lower in obese patients with (p < 0.01) and without (p < 0.05) T2D compared to lean volunteers while obese patients with T2D exhibited decreased GLP-1 levels at baseline (p < 0.05) and 120 min (p < 0.01) after the OGTT. Importantly, higher (p < 0.05) pre-operative GLP-1 concentrations were found in patients with T2D remission after RYGB. We also revealed that exendin-4, a GLP-1 agonist, downregulated the expression of inflammation-related genes (IL1B, IL6, IL8, TNF) and, conversely, upregulated the mRNA levels of ADIPOQ in human visceral adipocytes. Furthermore, exendin-4 blocked (p < 0.05) LPS-induced inflammation in human adipocytes via downregulating the expression and secretion of key inflammatory markers. Conclusions: Our data indicate that GLP-1 may contribute to glycemic control and exert a role in T2D remission after RYGB. GLP-1 is also involved in limiting inflammation in human visceral adipocytes.

Background: Current evidence suggests that local anesthetic wound infiltration should be employed as part of multimodal postoperative pain management. There is scarce data concerning the benefits of this anesthetic modality in laparoscopic weight loss surgery. Therefore, we analyzed the influence of trocar site infiltration with bupivacaine on the management of postoperative pain in laparoscopic bariatric surgery. Methods: This retrospective randomized study included 47 patients undergoing primary obesity surgery between January and September 2014. Laparoscopic gastric bypass was performed in 39 cases and sleeve gastrectomy in 8 cases. Patients were stratified into two groups depending on whether preincisional infiltration with bupivacaine and epinephrine was performed (study group, 27 patients) or not (control group, 20 patients). Visual analogue scale (VAS), International Pain Outcomes questionnaire, and rescue medication records were reviewed to assess postoperative pain. Results: VAS scores in the study group and sleeve gastrectomy group were lower than those in the control and gastric bypass groups in the first 4 h postoperatively without reaching statistical significance (p > 0.05). VAS scores did not differ in any other period of time. No statistically significant differences in pain perception were registered according to the patient's pain outcomes questionnaire or the need for rescue medication. Conclusions: The present study did not conclusively prove the efficacy of bupivacaine infiltration by any of the three evaluation methods analyzed. Nevertheless, preincisional infiltration provides good level of comfort in the immediate postoperative period when analgesia is most urgent.
