Morphofunctional nutritional assessment in clinical practice: A new approach to assessing nutritional status

Producción CientíficaThis Special Issue of Nutrients titled “Morphofunctional Nutritional Assessment in Clinical Practice” is oriented to the diagnosis of disease-related malnutrition (DRM). Disease-related malnutrition is a highly prevalent pathology which has become a great challenge to healthcare systems. This disease has a prevalence between 20 and 50% in hospitalized patients [1,2]. Malnutrition can be associated with other conditions such sarcopenia, defined as a loss of muscle mass and function. [Texto extraído del artículo de Daniel Antonio de Luis Román]

Effect of Wakame and Carob Pod Snacks on Non-Alcoholic Fatty Liver Disease

Snacks combining different functional ingredients could represent a useful therapeutic strategy against NAFLD. The present study aimed to analyze the effect of two snack formulations based on carob and wakame flour in the treatment for NAFLD in rats. For this purpose, metabolic syndrome was induced in 50 adult rats by a high-fat high-fructose diet over eight weeks. After this period, rats were fed either normal calorie diets supplemented or not with snack A (1/50 wakame/carob pod) and snack B (1/5 wakame/carob pod) for four additional weeks. After sacrifice, liver composition and serum parameters were analyzed. Different pathways of triacylglycerol metabolism in liver were studied including fatty acid oxidation, fatty acid synthesis, triglyceride assembly and release, fatty acid uptake and glucose uptake. Oxidative stress was also measured. Snack treatment, and mainly B snack, reduced liver triacylglycerol levels by increasing fat oxidation. Moreover, this snack reduced oxidative stress. Therefore, this snack formulation could represent an interesting tool useful for fatty liver treatment.This study has been supported by the National Institute for Agricultural and Food Research and Technology of Spain (INIA: RTA2014-0037-C02), Instituto de Salud Carlos III (CIBERobn) and Basque Government (IT-572-13)

Combined strategy using high hydrostatic pressure, temperature and enzymatic hydrolysis for development of fibre-rich ingredients from oat and wheat by-products

Producción CientíficaWheat bran (WB) and oat hull (OH) are two interesting undervalued cereal processing sources rich in total dietary fibre (TDF) and other associated bioactive compounds, such as β-glucans and polyphenols. The aim of this study was to optimise a combination chemical (enzymes) and physical (high hydrostatic pressure-temperature) strategies to increase the bioaccessibility of bioactive compounds naturally bound to the bran and hull outer layers. WB and OH were hydrolysed using food-grade enzymes (UltraFloXL and Viscoferm, for WB and OH, respectively) in combination with HPP at different temperatures (40, 50, 60 and 70 °C) and hydrolysis either before or after HPP. Proximal composition, phytic acid, β-glucans, total phenolics (TPs) and total antioxidant activity (TAC) were evaluated to select the processing conditions for optimal nutritional and bioactive properties of the final ingredients. The application of the hydrolysis step after the HPP treatment resulted in lower phytic acid levels in both matrices (WB and OH). On the other hand, the release of β-glucan was more effective at the highest temperature (70 °C) used during pressurisation. After the treatment, the TP content ranged from 756.47 to 1395.27 µmol GAE 100 g−1 in WB, and OH showed values from 566.91 to 930.45 µmol GAE 100 g−1. An interaction effect between the temperature and hydrolysis timing (applied before or after HPP) was observed in the case of OH. Hydrolysis applied before HPP was more efficient in releasing OH TPs at lower HPP temperatures (40–50 °C); meanwhile, at higher HPP temperatures (60–70 °C), hydrolysis yielded higher TP values when applied after HPP. This effect was not observed in WB, where the hydrolysis was more effective before HPP. The TP results were significantly correlated with the TAC values. The results showed that the application of optimal process conditions (hydrolysis before HPP at 60 or 70 °C for WB; hydrolysis after HPP at 70 °C for OH) can increase the biological value of the final ingredients obtained.Ministerio de Ciencia, Innovación y Universidades/Agencia Estatal de Investigación (AEI) y Fondo Social Europeo (FSE)/Unión Europea (UE) - (grant PRE2019-087824

SPECT/TC con análogos de la somatostatina en el diagnóstico de los tumores neuroendocrinos

Owing to the recent introduction of gamma cameras with integrated computed tomography imaging capability, which combine functional and anatomical imaging in one device, the direct acquisition of co-registered images has become possible. Multiple studies have concluded that single photon emission computed tomography/computed tomography (SPECT/CT) provides an important added value to the conventional somatostatin receptor scintigraphy imaging in the diagnosis of neuroendocrine tumours.Debido a la reciente aparición de equipos híbridos SPECT/CT que combinan imágenes de tomografía por emisión de fotón único (SPECT) e imágenes de tomografía computarizada (TC), es posible adquirir imágenes funcionales e imágenes anatómicas en una única sesión. Numerosos estudios han mostrado el valor añadido del SPECT/TC a la gammagrafía de receptores de somatostatina en el diagnóstico de los tumores neuroendocrinos

Role of the rs10401670 variant in the resistin gene on the metabolic response after weight loss secondary to a high‐fat hypocaloric diet with a Mediterranean pattern

Producción CientíficaBackground:The single nucleotide polymorphism (SNP) (rs10401670) of theRETNgene has been associated with metabolic disorder in obese subjects andhas scarcely been evaluated after dietary interventions. The present studyaimed to analyse the effects of thers10401670 RETNgene polymorphismon metabolic changes secondary to weight loss and secondary to a high‐fathypocaloric diet with a Mediterranean dietary pattern.Methods:A Caucasian population comprising 284 obese patients withoutdiabetes mellitus was analysed. Before and after 3 months of a high‐fathypocaloric diet with a Mediterranean pattern, an anthropometric evaluation,an assessment of nutritional intake and a biochemical analysis were per-formed. A statistical analysis was conducted for the combinedCTandTTas agroup and for wild‐typeCCas a second group.Results:Decreases in weight, body mass index (BMI), fat mass, systolic bloodpressure and waist circumference were similar in both genotypes groups. InTallele carriers, insulin, homeostatic model assessment for insulin resistance(HOMA‐IR), triglycerides and C‐reactive protein levels were decreased.The decrease in these parameters was statistically significant for triglycerides(−22.3 ± 9.3 mg dl–1:p= 0.03), C‐reactive protein (−2.8 ± 0.5 mg dl–1:p= 0.03), insulin (−7.4 ± 2.9 mUI L–1:p= 0.03) and HOMA‐IR (−2.4 ± 1.0:p= 0.02). Leptin levels were decreased in both genotypes groups after thehypocaloric diet, as well as the anthropometric parameters BMI, weight, waistcircumference and fat mass. Resistin and adiponectin levels remained un-changed in both groups.Conclusions:In the present study, we have detected a significant associationbetween theTallele of this SNP and a better response of insulin resistance,triglycerides and C‐reactive protein compared to nonTallele carriers afterweight loss with a high‐fat hypocaloric diet and a Mediterranean diet

Role of Beta2 adrenergic receptor polymorphism (rs1042714) on body weight and glucose metabolism response to a meal-replacement hypocaloric diet

Producción CientíficaThe Beta2-adrenergic receptor (ADRB2) is involved in energy balance regulation. The objective of our study was to evaluate the role of rs1042714 genetic variant of ADRB2 gene on weight loss, body composition and metabolic changes secondary to partial Meal replacement (pMR) hypocaloric diet in women with obesity. G allele of rs rs1042714 predicts the magnitude of weight loss resulting from a pMR diet. These adiposity improvements produce a better improvement of insulin resistance and percentage of impaired glucose metabolism in G allele carriers

Predictive value and dynamic risk stratification of high sensitive basal or stimulated thyroglobulin assay in a long-term thyroid carcinoma cohort

Producción CientíficaPurpose: To evaluate the predictive value of the rhTSH thyroglobulin stimulation test (rhTSH-Tg) compared to basal high- sensitive thyroglobulin (hs-Tg) under TSH suppressive therapy at 12 months after the completion of initial treatment to predict the long-term response and Dynamic Risk Stratification (DRS) at the last follow-up visit in a long-term DTC cohort. Methods: Prospective study in 114 DTC patients (77.2% women, mean age 46.4 ± 14.1 years old, median/IQR evolution 6.7[3.1–8.0] years) from 2013 to 2020 undergoing total thyroidectomy and radioiodine ablation in whom hs-Tg and rhTSH- Tg was performed 12 months after completing initial treatment. Pearson correlation, receiving operating characteristics (ROC) and DRS at initial and last follow-up visit were analyzed. Results: hs-Tg and rhTSH-Tg show a strong positive linear correlation (r = 0.864, p < 0.001). The diagnostic performance of initial hs-Tg and rhTSH-Tg levels were evaluated via ROC-AUC as a predictor of excellent response (ER) in the last follow-up visit. Hs-Tg showed a better AUC (0.969, 95%CI = 0.941–0.997) than rhTSH-Tg (0.944, 95%IC = 0.905–0.984; p < 0.001). The hs-Tg and rhTSH-Tg cutoff point of highest sensitivity (S) and specificity (E) was 0.110 and 0.815 ng/dl, respectively. Hs-Tg showed a higher diagnostic accuracy than rhTSH-Tg (S = 100% vs 96.8%, E = 84.3% vs 84.3%, NPV = 100% vs 98.6%, PPV = 70.5% vs 69.7%; p < 0.05). The DRS based on initial hs-Tg showed better ability to predict ER (93.3% vs 86.7%) and biochemical incomplete response (53.3%vs13.3%) in the last follow-up visit compared to rhTSH-Tg. Conclusions: Both initial hs-Th and rhTSH-Tg were good predictors of long-term ER. In patients with hs-Tg, the rhTSH-test did not provide relevant prognosis information. An ER after initial treatment was associated with a very high NPV at subsequent follow-up.Publicación en abierto financiada por el Consorcio de Bibliotecas Universitarias de Castilla y León (BUCLE), con cargo al Programa Operativo 2014ES16RFOP009 FEDER 2014-2020 DE CASTILLA Y LEÓN, Actuación:20007-CL - Apoyo Consorcio BUCL

Vitamin D receptor (VDR) gene polymorphisms modify the response to vitamin D supplementation: A systematic review and meta-analysis

Producción CientíficaThe vitamin D receptor (VDR), a member of the nuclear receptor superfamily of transcriptional regulators, is crucial to calcitriol signalling. VDR is regulated by genetic and environmental factors and it is hypothesised that the response to vitamin D supplementation could be modulated by genetic variants in the VDR gene. The best studied polymorphisms in the VDR gene are Apal (rs7975232), BsmI (rs1544410), Taql (rs731236) and Fokl (rs10735810). We conducted a systematic review and meta-analysis to evaluate the response to vitamin D supplementation according to the BsmI, TaqI, ApaI and FokI polymorphisms. We included studies that analysed the relationship between the response to vitamin D supplementation and the genotypic distribution of these polymorphisms. We included eight studies that enrolled 1038 subjects. The results showed no significant association with the BsmI and ApaI polymorphisms (p = 0.081 and p = 0.63) and that the variant allele (Tt+tt) of the TaqI polymorphism and the FF genotype of the FokI variant were associated with a better response to vitamin D supplementation (p = 0.02 and p < 0.001). In conclusion, the TaqI and FokI polymorphisms could play a role in the modulation of the response to vitamin D supplementation, as they are associated with a better response to supplementation

Adiponectin gene variant rs3774261, effects on lipid profile and adiponectin levels after a high polyunsaturated fat hypocaloric diet with Mediterranean pattern

Producción CientíficaThe role of ADIPOQ gene variants on metabolic improvements after weight change secondary to different hypocaloric diets remained unclear. We evaluate the effect of rs3774261 of ADIPOQ gene polymorphism on biochemical improvements and weight change after high polyunsaturated fat hypocaloric diet with a Mediterranean dietary pattern for 12 weeks. A population of 361 obese subjects was enrolled in an intervention trial with a calorie restriction of 500 calories over the usual intake and 45.7% of carbohydrates, 34.4% of fats, and 19.9% of proteins. The percentages of different fats was; 21.8% of monounsaturated fats, 55.5% of saturated fats, and 22.7% of polyunsaturated fats. Before and after intervention, an anthropometric study, an evaluation of nutritional intake and a biochemical evaluation were realized. All patients lost weight regardless of genotype and diet used. After 12 weeks with a similar improvement in weight loss (AA vs. AG vs. GG); total cholesterol (delta: −28.1 ± 2.1 mg/dL vs. −14.2 ± 4.1 mg/dL vs. −11.0 ± 3.9 mg/dL; p = 0.02), LDL cholesterol (delta: −17.1 ± 2.1 mg/dL vs. −6.1 ± 1.9 mg/dL vs. −6.0 ± 2.3 mg/dL; p = 0.01), triglyceride levels (delta: −35.0 ± 3.6 mg/dL vs. 10.1 ± 3.2 mg/dL vs. −9.7 ± 3.1 mg/dL; p = 0.02), C reactive protein (CRP) (delta: −2.3 ± 0.1 mg/dL vs. −0.2 ± 0.1 mg/dL vs. −0.2 ± 0.1 mg/dL; p = 0.02), serum adiponectin (delta: 11.6 ± 2.9 ng/dL vs. 2.1 ± 1.3 ng/dL vs. 3.3 ± 1.1 ng/dL; p = 0.02) and adiponectin/leptin ratio (delta: 1.5 ± 0.1 ng/dL vs. 0.3 ± 0.2 ng/dL vs. 0.4 ± 0.3 ng/dL; p = 0.03), improved only in AA group. AA genotype of ADIPOQ variant (rs3774261) is related with a significant increase in serum levels of adiponectin and ratio adiponectin/leptin and decrease on lipid profile and C-reactive protein (CRP)
