Influenza vaccination among multiple sclerosis patients during the COVID-19 pandemic

In the context of the COVID-19 pandemic, the co-circulation of influenza and SARS-CoV-2 viruses may have severe complications for vulnerable populations. For this reason, the World Health Organization pointed to the 2020–2021 anti-influenza campaign as being of special relevance. Our aim was to assess the 2020–2021 influenza vaccination coverage, and its associated factors, among patients in a Spanish multiple sclerosis (MS) unit. A cross–sectional study was conducted. People attending the MS unit of the Clinical Hospital of Zaragoza during 2020 were included. Variables were obtained by reviewing records. Associations with 2020–2021 influenza vaccination were analyzed using bivariate analysis and a multiple logistic regression model. A total of 302 patients were studied; 62.6% were women, whose mean age (standard deviation) was 47.3 (11.5) years. The 2020–2021 influenza vaccination coverage was 55.3% (59.8% in women and 47.8% in men). A total of 89.7% had at least one other indication for vaccination (e.g., immunosuppressive treatment in 225 patients). The variables associated with getting vaccinated were being female (adjusted odds ratio (95% confidence interval) (aOR (95%CI) = 2.12 (1.12–3.99)), having received the 2019–2020 influenza vaccine (aOR (95%CI) = 31.82 (14.71–68.86)) and being born in Spain (aOR (95%CI) = 12.91 (1.07–156.28)). Coverage is moderate compared to other countries. It is necessary to develop strategies to improve it, especially in men and those born outside Spain

Effects of dietary free fatty-acid content and saturation degree on lipid-class composition and fatty-acid digestibility along the gastrointestinal tract in broiler starter chickens

The aim of the present study is to assess the effect of the dietary free fatty acid (FFA) content and dietary fat saturation degree on the fatty-acid (FA) digestibility and lipid-class content along the gastrointestinal tract and excreta in broiler chickens. The 8 experimental diets resulted from replacing crude soybean oil with soybean acid oil from chemical refining, or crude palm oil with palm FA distillate from physical refining. Thus, there were 4 soybean and 4 palm diets with 6% added fat varying in their FFA% (5, 15, 35, and 50%). Samples of digestive content (gizzard, duodenum, jejunum, and ileum) and excreta were collected at 14 D for the determination of the FA digestibility and lipid-class content. The total FA digestibility coefficients reported for the chickens fed S diets in the jejunum, ileum, and excreta were higher than for those fed P diets (P ≤ 0.02). The general greater digestibility of the unsaturated diets was mainly explained by a higher contribution of the ileum to the absorption of saturated FA. The dietary FFA content mainly affected the FA absorption process. The diets with 50% FFA presented lower saturated FA digestibility coefficients in the jejunum and ileum (P ≤ 0.03), and higher content of FFA in the ileum and excreta (P ≤ 0.014), in comparison to the diets with 5% FFA. The 15% FFA diets were not different from the 5% FFA diets, regarding the saturated FA digestibility in the jejunum and excreta, and the FFA content in the ileum and excreta. It was concluded that unsaturated diets with moderate content of dietary FFA (up to 15%) could be used in broiler-chicken starter diets, as they led to similar FA absorption and performance results to the diets with the lowest dietary FFA content. From the present study, it has also been concluded that dietary saturated FA content has a greater impact on FA absorption than the dietary FFA content has

Influenza vaccination coverage among multiple sclerosis patients: evolution over time and associated factors

Our objective was to determine the influenza vaccination rate in a Spanish cohort of multiple sclerosis (MS) patients. A retrospective cohort study was carried out. Patients who attended the MS unit of the Lozano Blesa Hospital of Zaragoza between January 2015 and 2020 were included. The variables were obtained by reviewing the specialized and primary care records. Associations between receiving the vaccine in each flu season and the other variables were analyzed using bivariate analysis and multiple logistic regression models. A total of 260 patients were studied, with a median age of 31 years at the time of diagnosis. A total of 62.3% (162/260) were women. Vaccination coverage ranged from 20.4% in the 2015–2016 and 2016–2017 seasons to 41.5% in the 2019–2020 season (p = 0.000). Having been vaccinated in the previous season (ORa: 16.47–390.22; p = 0.000) and receiving a vaccination recommendation from the hospital vaccination unit (ORa: 2.44–3.96; p < 0.009) were associated with being vaccinated. The coverage is in an intermediate position compared to other countries. It is necessary to improve the referral system of these patients to the hospital vaccination unit because the information obtained by this service contributed to higher vaccination rates

Spanish children's diet: compliance with nutrient and food intake guidelines

OBJECTIVE: To compare the diet of Spanish children against the nutrient and food intake guidelines. To calculate an index of overall diet quality and check its validity against nutrient intake. DESIGN AND SETTING: Cross-sectional study in four cities in Spain, where information on food and nutrient intake was obtained from schoolchildren through a food frequency questionnaire. PARTICIPANTS: The sample included 1112 children (overall response rate of 85%) attending public and private schools and aged 6-7 y. Children were selected through random cluster sampling in schools, and stratified by sex and socioeconomic level. MAIN OUTCOME MEASURES: Mean nutrient intake, number of food servings, and the percentage of children who meet recommended nutrient and food-serving intake levels. The overall dietary quality was assessed using the Healthy Eating Index (HEI). RESULTS: Mean micronutrient intake exceeded 100% of the recommended dietary allowances, except for vitamin B6, which registered a mean intake of 77.1%. For almost all children, intake of saturated fat was above, and that of carbohydrate below, the recommended level, in contrast to the relatively high compliance with the recommendations for poly- and monounsaturated fatty acid, salt and fiber intake (69.7, 43.7, 40.7, and 30.1%, respectively). Consumption of food servings for each of the five American pyramid food groups came close to or exceeded USDA guidelines, with the exception of cereals, with 5.4 servings per day. The mean score obtained in the HEI was 64.6. Children who complied with all the food guide pyramid recommendations registered a higher dietary variety and a healthier nutritional profile. CONCLUSIONS: Children aged 6-7 y show scant compliance with the macronutrient goals for healthy eating. Micronutrient intake is adequate in general, yet there are small groups of children with risk of deficient intake of vitamins B6 and D. While Spanish children's eating habits are reasonably in line with American food guide pyramid guidelines, consumptions of cereals and fruit should be improved.This study was partly funded by grants from the Inter-national Olive Oil Board (Consejo Oleı ́cola Internacional),Comunidad de Madrid, Fundacio ́n Pedro Barrie ́de laMaza, and Fundacio ́n Eugenio Rodrı ́guez Pascua

Food sources of nutrients in the diet of Spanish children: the Four Provinces Study

The aim of the present study was to assess the principal food sources of energy and nutrients among Spanish children. We used a cross-sectional study design, based on results obtained from a food-frequency questionnaire. The sample included 1112 children, aged 6-7 years, from Cadiz, Madrid, Orense and Murcia, Spain. Children were selected through random cluster-sampling in schools. We analysed the percentage contributed by each food item to total energy and nutrient intake. The most important food sources were: white bread in the case of carbohydrate (13.4 %); olive oil in the case of total lipids (18.3 %) and monounsaturated fatty acids (29.2 %); whole milk in the case of protein (10.2 %) and saturated fatty acids (14.9 %); chips (French fried potatoes) in the case of polyunsaturated fatty acids (30.4 %). The greatest proportion of Na, consumed in excess, came from salt added to meals. Ham ranked second as a source of saturated fats. Fruits and green leafy vegetables proved to have great relevance as sources of fibre and vitamins, though with regard to the latter, it was observed that fortified foods (breakfast cereals, dairy products, fruit juices, etc.) had come to play a relevant role in many cases. In conclusion, the nutritional profile of Spanish school-aged children aged 6-7 years could be improved by nutritional policies targeted at limiting their consumption of ham (cured or cooked) and of salt added to meals, replacing whole milk with semi-skimmed milk, encouraging the consumption of products rich in complex carbohydrates already present in children's diets (bread, pasta, rice) and promoting less fatty ways of cooking food.This study was partly funded by grants from the Inter-national Olive Oil Board (Consejo Oleı ́cola Internacional),Madrid Regional Authority (Comunidad de Madrid), PedroBarrie ́de la Maza Foundation and Eugenio Rodrı ́guezPascual FoundationS

Greater dietary variety is associated with better biochemical nutritional status in Spanish children: the Four Provinces Study

BACKGROUND AND AIM: Although dietary variety has been associated with a better nutritional profile, its possible role in obesity raises doubts about its overall health benefits. In this study, we examined the association between dietary variety and anthropometric variables, food intake and various food intake biomarkers in Spanish children. METHODS AND RESULTS: This was a cross-sectional study of 1112 children aged 6-7 years from Cadiz, Murcia, Orense and Madrid, who were selected by means of the random cluster-sampling of schools. Information concerning food and nutrient intake was obtained using a food frequency questionnaire, and a dietary variety index (DVI) was calculated on the basis of the number of different foods consumed more than once a month. The anthropometric variables (weight and height), and plasma lipid and vitamin levels were determined using standardised methods. Our results show that the body mass index (BMI) did not vary substantially as a function of DVI: it was 16.9 in the lowest DVI tertile and 17.2 in the highest (p=0.20). Unlike BMI, the DVI positively correlated (p<0.05) with the plasma levels of alpha and beta-carotene, lycopene, retinol, alpha-tocopherol and vitamin E, with energy intake, and with most of the foods, particularly vegetables, fruit and sausages (respective correlation coefficients of 0.43, 0.26 and 0.23). CONCLUSIONS: Dietary variety is associated with a better food and nutritional profile in Spanish children. Nevertheless, the presence of a positive association between the DVI and energy intake, and the consumption of sausages and pre-cooked products calls for the recommendation of a varied diet of healthy foods, such as cereals (especially whole grains), fruits and vegetables

Transcriptome analyses throughout chili pepper fruit development reveal novel insights into the domestication process

Chili pepper (Capsicum spp.) is an important crop, as well as a model for fruit development studies and domestication. Here, we performed a time-course experiment to estimate standardized gene expression profiles with respect to fruit development for six domesticated and four wild chili pepper ancestors. We sampled the transcriptomes every 10 days from flowering to fruit maturity, and found that the mean standardized expression profiles for domesticated and wild accessions significantly differed. The mean standardized expression was higher and peaked earlier for domesticated vs. wild genotypes, particularly for genes involved in the cell cycle that ultimately control fruit size. We postulate that these gene expression changes are driven by selection pressures during domestication and show a robust network of cell cycle genes with a time shift in expression, which explains some of the differences between domesticated and wild phenotypes

Prevención secundaria tras un síndrome coronario agudo. Resultados a medio plazo de un programa de rehabilitación cardiaca

Introducción Los Programas de Rehabilitación Cardiaca han adquirido gran relevancia como herramienta para mejorar el pronóstico y la calidad de vida de pacientes que han presentado un síndrome coronario agudo. Objetivo Evaluar los resultados de un programa de rehabilitación cardiaca a medio plazo. Materiales y métodos Estudio descriptivo retrospectivo de 121 pacientes que presentaron un síndrome coronario agudo y fueron incluidos en el programa de rehabilitación cardiaca. Se analizaron las características demográficas, antropométricas, analíticas y de capacidad funcional a la inclusión, tras finalizar el programa presencial y a los 12 meses. Resultados La edad media fue 54 ± 7 años. El factor de riesgo cardiovascular más prevalente fue el sobrepeso/obesidad (88, 4%). Tras la finalización del programa de rehabilitación cardiaca disminuyeron significativamente los valores de colesterol LDL (81, 1 ± 28, 7 vs. 76, 5 ± 31, 5 mg/dl; p 0, 03). Un porcentaje significativo de diabéticos alcanzaron objetivos de Hb A1c < 7% (50% vs. 68, 5%; p 0, 01). El perímetro abdominal mostró una disminución estadísticamente significativa (100, 8 ± 12, 8 vs. 99, 5 ± 12, 3 cm; p 0, 004). El 89, 3% de los pacientes mejoraron su capacidad funcional. En la revisión anual la mayoría de los parámetros estudiados mostraron una discreta tendencia negativa. Un 47, 36% de los fumadores a la inclusión mantenían el hábito tabáquico al año. Conclusiones Los programas de rehabilitación cardiaca mejoran el control de los factores de riesgo cardiovascular, cambios de estilo de vida y capacidad funcional en los pacientes que han sufrido un síndrome coronario agudo. Es preciso reforzar las estrategias de control para mantener estos beneficios a medio-largo plazo. Introduction: Cardiac rehabilitation programmes have become a very important tool for improving the prognosis and quality of life of patients that have suffered an acute coronary syndrome. Objective: To evaluate the medium-term results of a cardiac rehabilitation programme. Materials and methods: A descriptive study of 121 patients that presented with an acute coronary syndrome and were included in a cardiac rehabilitation programme. An analysis was performed on the demographic and anthropometric characteristics, as well as laboratory tests and functional capacity on inclusion, after finishing the programme, and at 12 months. Results: The mean age of the patients was 54 ± 7 years. The most prevalent cardiovascular risk factor was overweight / obesity (88.4%). After finishing the cardiac rehabilitation programmes, the LDL Cholesterol values significantly decreased (81.1 ± 28.7 vs. 76.5 ± 31.5 mg/dl; P =.03). A significant percentage of diabetics reached objectives of an Hb A1c < 7% (50% vs. 68.5%; P =.01). The abdominal circumference showed a statistically significant decrease (100.8 ± 12.8 vs. 99.5 ± 12.3 cm; P =.004). An improvement in functional capacity was observed in 89.3% of the patients. In the annual review, the majority of the parameters studied showed a slight negative trend. Just under half (47.36%) of smokers at inclusion maintained the tobacco habit at one year. Conclusions: Cardiac rehabilitation programmes improve the control of cardiovascular risk factors, changes in life style and functional capacity in patients that had suffered an acute coronary syndrome. Control strategies need to be enforced in order to maintain these benefits in the medium-long term

Alpha band disruption in the AD-continuum starts in the subjective cognitive decline stage: a MEG study

The consideration of Subjective Cognitive Decline (SCD) as a preclinical stage of AD remains still a matter of debate. Alpha band alterations represent one of the most significant changes in the electrophysiological profile of AD. In particular, AD patients exhibit reduced alpha relative power and frequency. We used alpha band activity measured with MEG to study whether SCD and MCI elders present these electrophysiological changes characteristic of AD, and to determine the evolution of the observed alterations across AD spectrum. The total sample consisted of 131 participants: 39 elders without SCD, 41 elders with SCD and 51 MCI patients. All of them underwent MEG and MRI scans and neuropsychological assessment. SCD and MCI patients exhibited a similar reduction in alpha band activity compared with the no SCD group. However, only MCI patients showed a slowing in their alpha peak frequency compared with both SCD and no SCD. These changes in alpha band were related to worse cognition. Our results suggest that AD-related alterations may start in the SCD stage, with a reduction in alpha relative power. It is later, in the MCI stage, where the slowing of the spectral profile takes place, giving rise to objective deficits in cognitive functioning.This study was supported by two projects from the Spanish Ministry of Economy and Competitiveness, PSI2009-14415-C03-01 and PSI2012-38375-C03-01, a predoctoral fellowship from the Ministry of Economy and Competitiveness to DLS (PSI2012-38375-C03-01), and three predoctoral fellowships from the Ministry of Education to RB,NS,ICRR (FPU13/06009, FPU14/07164, FPU13/02064)

Saturated fat in the diet of Spanish children: relationship with anthropometric, alimentary, nutritional and lipid profiles

OBJECTIVE: To compare the anthropometric, alimentary, nutritional and lipid profiles and global diet quality of Spanish children according to saturated fat intake. DESIGN: This was a cross-sectional study. Food data were collected using a food-frequency questionnaire. SUBJECTS AND METHODS: The sample included 1112 children of both sexes, aged between 6 and 7 years, selected by means of random cluster sampling in schools. The plasma lipid profile included measurements of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, apolipoprotein A1 (apoA1) and apolipoprotein B (apoB). Global diet quality was evaluated by the Dietary Variety Index (DVI) and the Healthy Eating Index (HEI). RESULTS: Energy intake, DVI and HEI of children from the lower quartile of saturated fat intake (LL) were higher (P<001) than in the remaining children (UL). However, there were no significant differences in average height or weight between groups. The UL children had lower intakes of meat, fish, vegetables, fruits and olive oil and a higher intake of dairy products (P<0.001). The intakes of fibre, vitamins C, D, B6, E and folic acid were higher in the LL children, who had lower intakes of vitamin A and calcium. The ratios LDL-C/HDL-C and apoB/apoA1 were lower (P=0.04) in the LL children (1.87 and 0.52, respectively) than in the UL children (2.02 and 0.54, respectively). CONCLUSIONS: The growth rate of children does not seem to be affected by the level of saturated fat intake. Furthermore, at the levels of intake observed in this study, diets with less saturated fat are associated with better alimentary, nutritional and plasma lipid profiles.This study was partly funded by grants from the Fondo deInvestigacio ́n Sanitaria (FIS 020994, FIS02/3104) and theMinisterio Agricultura Pesca y Alimentacio ́n.
