Efectos del consumo del beta-glucano de la avena sobre el colesterol sanguíneo: una revisión

Elevated total and low density lipoprotein (LDL) cholesterol levels are considered major risk factors for coronary heart disease. Oat is a cereal that is a good source of proteins, fat, minerals and vitamins, as well as soluble fiber, including beta-glucans. Due to the physicochemical characteristics of the beta-glucan, it has been proposed that oats may help reduce blood cholesterol levels and help control postprandial plasma glucose and insulin response. A large body of clinical studies suggests that the consumption of at least 3 g per day of oat betaglucan, as part of a diet low in saturated fat and cholesterol, may reduce the risk of coronary heart disease, which has been approved by several regulatory agencies, as the Food and Drug Administration in the USA and the European Food Safety Authority in Europe.Las cifras sanguíneas de colesterol total y de lipoproteínas de baja densidad (LDL) elevadas se consideran como uno de los más importantes factores de riesgo de enfermedad coronaria. La avena es un cereal rico en proteínas, lípidos, vitaminas, minerales y fibra soluble, entre las que se incluye el beta-glucano. Debido a las características físico-químicas del beta-glucano, se ha propuesto que la avena pudiera contribuir a disminuir las cifras de colesterol sanguíneo, así como a controlar la glucosa plasmática postprandial y la respuesta insulínica. Numerosos estudios señalan que el consumo de un mínimo de 3 g/día de beta-glucano de forma regular, como parte de una dieta con un bajo contenido en grasa saturada y colesterol, puede contribuir a disminuir el riesgo de enfermedad coronaria, tal y como han aprobado diversas agencias reguladoras, como la Food and Drug Administration de Estados Unidos o la Agencia Europea de Seguridad Alimentaria

Association between Neutrophil-to-Lymphocyte Ratio with Abdominal Obesity and Healthy Eating Index in a Representative Older Spanish Population

Poor diet quality and obesity, especially abdominal obesity, have been associated with systemic inflammation. The neutrophil-to-lymphocyte Ratio (NLR) is an available and inexpensive inflammation biomarker. The aim of the present study was to determine the association of dietary patterns and obesity with an inflammatory state. A group of 1747 Spanish noninstitutionalized older adults individuals were included, and a food-frequency questionnaire was applied. The Global Food Score (GFS) and Healthy Eating Index for Spanish population (SHEI) were calculated. Weight, height and waist (WC) and hip circumferences were measured, and BMI, waist-to-height ratio (WHtR), and waist-to-hip ratio (WHR) determined. In addition, body-fat percentage was measured by bioimpedance. NLR was calculated (NLR ≥ p80: 2.6; 2.8 and 2.4 as inflammatory status in the entire population, men and women, respectively). The men with inflammatory status presented significative higher values of WC, WHtR, WHR, and body-fat percentage (101.82 ± 10.34 cm, 0.61 ± 0.06, 0.98 ± 0.06, and 31.68 ± 5.94%, respectively) than those with better inflammatory status (100.18 ± 10.22 cm, 0.59 ± 0.06, 0.97 ± 0.07, and 30.31 ± 6.16%, respectively). Those males with worse inflammatory state had lower scores for protein foods (OR = 0.898 (0.812–0.993); p = 0.037). The women with NLR ≥ 2.4 had higher WHtR and WHR (0.62 ± 0.09 and 0.91 ± 0.09) than those with NLR < 2.4 (0.60 ± 0.08 and 0.90 ± 0.08). In multiple linear regression analysis, NLR was positively related with WHtR and negatively related with SHEI score (β = 0.224 ± 0.094; R 2 = 0.060; p < 0.05 and β = −0.218 ± 0.101; R 2 = 0.061; p < 0.05), adjusting by sex, age, marital status, education level, smoking, hours of sleeping and inflammatory diseases. In women, the higher the SHEI and GFS scores were and the better meeting the aims of cereal and vegetable servings, the less the odds of inflammatory status (OR = 0.970 (0.948–0.992); p = 0.008; OR = 0.963 (0.932–0.995); p = 0.024; OR = 0.818 (0.688–0.974); p = 0.024 and OR = 0.829 (0.730–0.942); p = 0.004, respectively). WHtR and quality of diet is related to the inflammation status in older adults regardless to the sex

Overweight and General and Abdominal Obesity in a Representative Sample of Spanish Adults: Findings from the ANIBES Study

Objective. To analyze the anthropometric parameters from a representative sample of Spanish adults participating in ANIBES study and the prevalence of general and abdominal obesity. Methods. This cross-sectional study focused on 1655 adults aged 18-64 years. Weight, height, and waist circumference (WC) were evaluated, and body mass index (BMI) and waist to height ratio (WHtR) were calculated. A composite index combining BMI and WHtR was designed to establish five groups with different anthropometric status. Results. The prevalence of overweight (OW) was 35.8% and that of obesity was 19.9%. Obesity (OB) was higher among men (OR 1.725, 1.415-2.104; = 0.000) and each year of age increased the risk of obesity (OR 1.054, 1.045-1.064; = 0.000). The prevalence of abdominal obesity (WHtR ≥ 0.5) was 58.4%. Only 36.1% of the population had an optimal anthropometric situation (BMI &lt; 25 kg/m 2 , WHtR &lt; 0.5), whereas 50.1% had weight excess and high WHtR (BMI ≥ 25 kg/m 2 , WHtR ≥ 0.5). Conclusions. More than half of Spanish population has weight excess and cardiometabolic risk. The results of this study provide an understanding of the current anthropometric situation in the Spanish population, as a first step toward planning interventions and assessing their effectiveness in the future

Experience with Sunitinib in metastatic renal cell carcinoma (mRCC) patients: pooled analysis from 3 Spanish observational prospective studies

[Abstract] Background: A pivotal, randomized, phase III trial demonstrated a statistically significant superiority of sunitinib over interferon-α in metastatic renal cell carcinoma (mRCC) patients. Objective: To evaluate the effectiveness and safety of sunitinib in patients with advanced or mRCC in routine clinical practice. Methods: Retrospective pooled analysis of clinical data from three observational and prospective studies carried out between 2007 and 2011 in 33 Spanish hospitals. Tumor response, Progression-free survival (PFS) and overall survival (OS), and main sunitinib-related toxicities were registered. Results: 224 patients were analyzed. Median PFS 10.6 months (95% CI: 9.02–12.25), median OS 21.9 months (95% CI: 17.2–26.6). Objective response rate (ORR) 43.8% (95% CI: 36.8–50.7). Median time to PR was 3.8 months (95% CI: 3.86–5.99) and to CR 8.2 months (95% CI: 4.75–9.77). The most common ≥ grade-3 AEs were asthenia/fatigue (18.7%), hand-foot syndrome (6.2%), hypertension (5.8%) and neutropenia (4.8%). Hand-foot syndrome, diarrhea and mucositis were confirmed as independent predictors for PFS and/or OS in a multivariate analysis (p < 0.05) Conclusions: Outcomes with sunitinib in daily clinical practice resemble those obtained in clinical trials. Long-term benefit with sunitinib is possible in advanced RCC patients but the appropriate management of toxicities is mandatory to enable patients to remain on treatment

Usual Dietary Intake, Nutritional Adequacy and Food Sources of Calcium, Phosphorus, Magnesium and Vitamin D of Spanish Children Aged One to <10 Years. Findings from the EsNuPI Study

Bone problems in the population begin to be establish in childhood. The present study aims to assess the usual calcium, phosphorus, magnesium, and vitamin D intakes, along with the food sources of these nutrients, in Spanish children participating in the EsNuPI (Estudio Nutricional en Población Infantil Española) study. Two 24 h dietary recalls were applied to 1448 children (1 to <10 years) divided into two sub-samples: one reference sample (RS) of the general population [n = 707] and another sample which exclusively included children consuming enriched or fortified milks, here called “adapted milks” (AMS) [n = 741]. Estimation of the usual intake shows that nutrient intake increased with age for all nutrients except vitamin D. Using as reference the Dietary Reference Values from the European Food Safety Authority (EFSA), calcium and magnesium intakes were found to be below the average requirement (AR) and adequate intake (AI), respectively, in a considerable percentage of children. Furthermore, phosphorus exceeded the AI in 100% of individuals and vitamin D was lower than the AI in almost all children studied. The results were very similar when considering only plausible reporters. When analyzing the food sources of the nutrients studied, milk and dairy products contributed the most to calcium, phosphorus, magnesium, and vitamin D. Other sources of calcium were cereals and vegetables; for phosphorus: meat, meat products, and cereals; for magnesium: cereals and fruits; and, for vitamin D: fish and eggs. These results highlight the desirability of improving the intake concerning these nutrients, which are involved in bone and metabolic health in children. The AMS group appeared to contribute better to the adequacy of those nutrients than the RS group, but both still need further improvement. Of special interest are the results of vitamin D intakes, which were significantly higher in the AMS group (although still below the AI), independent of ageThis research was funded by Instituto Puleva de Nutrición (IPN)S

Longer intervals between SARS-CoV-2 infection and mRNA-1273 doses improve the neutralization of different variants of concern

The humoral immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern elicited by vaccination was evaluated in COVID-19 recovered individuals (Rec) separated 1-3 months (Rec2m) or 4-12 months (Rec9m) postinfection and compared to the response in naïve participants. Antibody-mediated immune responses were assessed in 66 participants by three commercial immunoassays and a SARS-CoV-2 lentiviral-based pseudovirus neutralization assay. Immunoglobulin (Ig) levels against SARS-CoV-2 spike were lower in naïve participants after two doses than in Rec after a single dose (p < 0.05). After two doses in Rec, levels of total Ig to receptor-binding domain were significantly increased in Rec9m compared to Rec2m (p < 0.001). The neutralizing potency observed in Rec9m was consistently higher than in Rec2m against variants of concern (VOCs) Alpha, Beta, Delta, and BA.1 sublineage of Omicron with 2.2-2.8-fold increases. Increasing the interval between SARS-CoV-2 infection and the vaccination with messenger RNA-based vaccines to more than 3 months generates a more efficient heterologous humoral immune response against VOCs by allowing enough time to mount a strong recall memory B cell response.This work is funded by Instituto de Salud Carlos III, a Spanish public body assigned to the Ministry of Science and Innovation that manages and promotes public clinical research related to Public Health, by Grants PI19CIII/00004 (José Alcamí and Francisco Díez‐Fuertes) and PI21CIII/00025 (Javier García‐Pérez and Mayte Pérez‐Olmeda), COVID‐19 Fund (Grants COV20/00679 (Javier García‐Pérez, Mayte Pérez‐Olmeda, José Alcamí, and Francisco Díez‐Fuertes) and COV20/00072 (Javier García‐Pérez, Mayte Pérez‐Olmeda, Almudena Ramírez‐García, María Castillo de la Osa, Rocio Layunta Acero, Laura Vicente‐Izquierdo, Cristina Avendaño‐Solá, and José Alcamí), and CIBERINFEC, co‐financed by the European Regional Development Fund (FEDER) “A way to make Europe.”S

Differences in meal patterns and timing with regard to central obesity in the ANIBES (‘Anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles in Spain’) study

OBJECTIVE:To study the association of meal patterns and timing with central obesity to identify the best dietary strategies to deal with the increasing obesity prevalence. DESIGN: A cross-sectional study performed on data from a representative sample of the Spanish population. Height and waist circumference were measured using standardized procedures and waist-to-height ratio (WHtR) was calculated. The sample was divided into those without central obesity (WHtR<0·5) and those with central obesity (WHtR≥0·5). SETTING: ANIBES ('Anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles in Spain') Study. SUBJECTS: Adults aged 18-64 years (n 1655; 798 men and 857 women). RESULTS: A higher percentage of people ate more than four meals daily in the group without central obesity and those with central obesity more frequently skipped the mid-afternoon snack than those without. Breakfasts containing >25 % of total energy intake and lunches containing >35 % of total energy intake were associated with increased likelihood of central obesity (OR=1·874, 95 % CI 1·019, 3·448; P15 % of total energy were associated with decreased likelihood of central obesity (OR=0·477, 95 % CI 0·313, 0·727; P<0·001 and OR=0·650, 95 % CI 0·453, 0·932; P<0·05, respectively). The variety of cereals, wholegrain cereals and dairy was higher in the population without central obesity. CONCLUSIONS: Our results suggest that 'what and when we eat' should be considered dietary strategies to reduce central obesity
