Medicinal Plant Leaf Extract From Sage and Lemon Verbena Promotes Intestinal Immunity and Barrier Function in Gilthead Seabream (Sparus aurata)
The inclusion of a medicinal plant leaf extract (MPLE) from sage (Salvia officinalis) and lemon verbena (Lippia citriodora), rich in verbascoside and triterpenic compounds like ursolic acid, was evaluated in gilthead seabream (Sparus aurata) fed a low fishmeal-based diet (48% crude protein, 17% crude fat, 21.7 MJ kg-1, 7% fishmeal, 15% fish oil) for 92 days. In particular, the study focused on the effect of these phytogenic compounds on the gut condition by analyzing the transcriptomic profiling (microarray analysis) and histological structure of the intestinal mucosa, as well as the histochemical properties of mucins stored in goblet cells. A total number of 506 differentially expressed genes (285 up- and 221 down-regulated) were found when comparing the transcriptomic profiling of the intestine from fish fed the control and MPLE diets. The gut transcripteractome revealed an expression profile that favored biological mechanisms associated to the 1) immune system, particularly involving T cell activation and differentiation, 2) gut integrity (i.e., adherens and tight junctions) and cellular proliferation, and 3) cellular proteolytic pathways. The histological analysis showed that the MPLE dietary supplementation promoted an increase in the number of intestinal goblet cells and modified the composition of mucinsâ glycoproteins stored in goblet cells, with an increase in the staining intensity of neutral mucins, as well as in mucins rich in carboxylated and weakly sulfated glycoconjugates, particularly those rich in sialic acid residues. The integration of transcriptomic and histological results showed that the evaluated MPLE from sage and lemon verbena is responsible for the maintenance of intestinal health, supporting gut homeostasis and increasing the integrity of the intestinal epithelium, which suggests that this phytogenic may be considered as a promising sustainable functional additive for aquafeeds.info:eu-repo/semantics/publishedVersio
Updating the Food-Based Dietary Guidelines for the Spanish Population: The Spanish Society of Community Nutrition (SENC) Proposal
Diet-related risk factors and physical inactivity are among the leading risk factors for disability and are responsible for a large proportion of the burden of chronic non-communicable diseases. Food-based dietary guidelines (FBDGs) are useful tools for nutrition policies and public health strategies to promote healthier eating and physical activity. In this paper, we discuss the process followed in developing the dietary guidelines for the Spanish population by the Spanish Society of Community Nutrition (SENC) and further explain the collaboration with primary healthcare practitioners as presented in the context of the NUTRIMAD 2018 international congress of SENC. From a health in all policies approach, SENC convened a group of experts in nutrition and public health to review the evidence on diet-health, nutrient intake and food consumption in the Spanish population, as well as food preparation, determinants and impact of diet on environmental sustainability. The collaborative group drafted the document and designed the graphic icon, which was then subject to a consultation process, discussion, and qualitative evaluation. Next, a collaborative group was established to plan a dissemination strategy, involving delegates from all the primary healthcare scientific societies in Spain. A product of this collaboration was the release of an attractive, easy-to-understand publication
Clustering of Dietary Patterns, Lifestyles, and Overweight among Spanish Children and Adolescents in the ANIBES Study
Weight gain has been associated with behaviors related to diet, sedentary lifestyle, and
physical activity. We investigated dietary patterns and possible meaningful clustering of physical
activity, sedentary behavior, and sleep time in Spanish children and adolescents and whether the
identified clusters could be associated with overweight. Analysis was based on a subsample
(n = 415) of the cross-sectional ANIBES study in Spain. We performed exploratory factor analysis
and subsequent cluster analysis of dietary patterns, physical activity, sedentary behaviors, and sleep
time. Logistic regression analysis was used to explore the association between the cluster solutions
and overweight. Factor analysis identified four dietary patterns, one reflecting a profile closer to the
traditional Mediterranean diet. Dietary patterns, physical activity behaviors, sedentary behaviors
and sleep time on weekdays in Spanish children and adolescents clustered into two different groups.
A low physical activity-poorer diet lifestyle pattern, which included a higher proportion of girls, and
a high physical activity, low sedentary behavior, longer sleep duration, healthier diet lifestyle pattern.
Although increased risk of being overweight was not significant, the Prevalence Ratios (PRs) for the
low physical activity-poorer diet lifestyle pattern were >1 in children and in adolescents. The healthier
lifestyle pattern included lower proportions of children and adolescents from low socioeconomic status backgrounds
Lifestyle Patterns and Weight Status in Spanish Adults: The ANIBES Study
Limited knowledge is available on lifestyle patterns in Spanish adults. We investigated
dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, sleep
time, and smoking in Spanish adults aged 18â64 years and their association with obesity. Analysis
was based on a subsample (n = 1617) of the cross-sectional ANIBES study in Spain. We performed
exploratory factor analysis and subsequent cluster analysis of dietary patterns, physical activity,
sedentary behaviors, sleep time, and smoking. Logistic regression analysis was used to explore the
association between the cluster solutions and obesity. Factor analysis identified four dietary patterns,
âTraditional DPâ, âMediterranean DPâ, âSnack DPâ and âDairy-sweet DPâ. Dietary patterns, physical
activity behaviors, sedentary behaviors, sleep time, and smoking in Spanish adults aggregated
into three different clusters of lifestyle patterns: âMixed diet-physically active-low sedentary lifestyle
patternâ, âNot poor diet-low physical activity-low sedentary lifestyle patternâ and âPoor diet-low physical
activity-sedentary lifestyle patternâ. A higher proportion of people aged 18â30 years was classified into
the âPoor diet-low physical activity-sedentary lifestyle patternâ. The prevalence odds ratio for obesity in
men in the âMixed diet-physically active-low sedentary lifestyle patternâ was significantly lower compared
to those in the âPoor diet-low physical activity-sedentary lifestyle patternâ. Those behavior patterns
are helpful to identify specific issues in population subgroups and inform intervention strategies.
The findings in this study underline the importance of designing and implementing interventions
that address multiple health risk practices, considering lifestyle patterns and associated determinants
Effectiveness of a stepped primary care smoking cessation intervention (ISTAPS study): design of a cluster randomised trial
Background: There is a considerable body of evidence on the effectiveness of specific interventions in individuals who wish to quit smoking. However, there are no large-scale studies testing the whole range of interventions currently recommended for helping people to give up smoking; specifically those interventions that include motivational interviews for individuals who are not interested in quitting smoking in the immediate to short term. Furthermore, many of the published studies were undertaken in specialized units or by a small group of motivated primary care centres. The objective of the study is to evaluate the effectiveness of a stepped smoking cessation intervention based on a trans-theoretical model of change, applied to an extensive group of Primary Care Centres (PCC). ethods/Design: Cluster randomised clinical trial. Unit of randomization: basic unit of care consisting of a family physician and a nurse, both of whom care for the same population (aprox. 2000 people). Intention to treat analysis. Study population: Smokers (n = 3024) aged 14 to 75 years consulting for any reason to PCC and who provided written informed consent to participate in the trial. Intervention: 6-month implementation of recommendations of a Clinical Practice Guideline which includes brief motivational interviews for smokers at the precontemplation - contemplation stage, brief intervention for smokers in preparation-action who do not want help, intensive intervention with pharmacotherapy for smokers in preparation-action who want help, and reinforcing intervention in the maintenance stage. Control group: usual care. Outcome measures: Self-reported abstinence confirmed by exhaled air carbon monoxide concentration of †10 parts per million. Points of assessment: end of intervention period and 1 and 2 years post-intervention; continuous abstinence rate for 1 year; change in smoking cessation stage; health status measured by SF-36. Discussion: The application of a stepped intervention based on the stages of a change model is possible under real and diverse clinical practice conditions, and improves the smoking cessation success rate in smokers, besides of their intention or not to give up smoking at baseline
Combined intermittent hypoxia and surface muscle electrostimulation as a method to increase peripheral blood progenitor cell concentration
Background: Our goal was to determine whether short-term intermittent hypoxia exposure, at a level well tolerated by healthy humans and previously shown by our group to increase EPO and erythropoiesis, could mobilizehematopoietic stem cells (HSC) and increase their presence in peripheral circulation. Methods: Four healthy male subjects were subjected to three different protocols: one with only a hypoxic stimulus (OH), another with a hypoxic stimulus plus muscle electrostimulation (HME) and the third with only muscle electrostimulation (OME). Intermittent hypobaric hypoxia exposureconsisted of only three sessions of three hours at barometric pressure 540 hPa (equivalent to an altitude of 5000 m) for three consecutive days, whereas muscular electrostimulation was performed in two separate periods of 25 min in each session. Blood samples were obtained from an antecubital vein on three consecutive days immediately before the experiment and 24 h, 48 h, 4 days and 7 days after the last day of hypoxic exposure. Results: There was a clear increase in the number of circulating CD34+ cells after combined hypobaric hypoxia and muscular electrostimulation. This response was not observed after the isolated application of the same stimuli. Conclusion: Our results open a new application field for hypobaric systems as a way to increase efficiency in peripheral HSC collection
Human Immunodeficiency Virus/Hepatits C Virus Coinfection in Spain: Elimination Is Feasible, but the Burden of Residual Cirrhosis Will Be Significant
Background: We assessed the prevalence of antibodies against hepatitis C virus (HCV-Abs) and active HCV infection in patients infected with human immunodeficiency virus (HIV) in Spain in 2016 and compared the results with those of similar studies performed in 2002, 2009, and 2015. Methods: The study was performed in 43 centers during October-November 2016. The sample was estimated for an accuracy of 2% and selected by proportional allocation and simple random sampling. During 2016, criteria for therapy based on direct-acting antiviral agents (DAA) were at least significant liver fibrosis, severe extrahepatic manifestations of HCV, and high risk of HCV transmissibility. Results: The reference population and the sample size were 38904 and 1588 patients, respectively. The prevalence of HCV-Abs in 2002, 2009, 2015, and 2016 was 60.8%, 50.2%, 37.7%, and 34.6%, respectively (P trend <.001, from 2002 to 2015). The prevalence of active HCV in 2002, 2009, 2015, and 2016 was 54.0%, 34.0%, 22.1%, and 11.7%, respectively (P trend <.001). The anti-HCV treatment uptake in 2002, 2009, 2015, and 2016 was 23.0%, 48.0%, 59.3%, and 74.7%, respectively (P trend <.001). In 2016, HCV-related cirrhosis was present in 7.6% of all HIV-infected individuals, 15.0% of patients with active HCV, and 31.5% of patients who cleared HCV after anti-HCV therapy. Conclusions: Our findings suggest that with universal access to DAA-based therapy and continued efforts in prevention and screening, it will be possible to eliminate active HCV among HIV-infected individuals in Spain in the short term. However, the burden of HCV-related cirrhosis will continue to be significant among HIV-infected individuals.This work was funded by grant Ref. no.

High efficacy of Sofosbuvir plus Simeprevir in a large cohort of Spanish cirrhotic patients infected with genotypes 1 and 4
[Abstract]
Background and Aims. Hepatitis C (HCV) therapy with Sofosbuvir (SOF)/Simeprevir (SMV) in clinical trials and realâworld clinical practice, showed high rates of sustained virological response (SVR) in nonâcirrhotic genotype (GT)â1 and GTâ4 patients. These results were slightly lower in cirrhotic patients. We investigated realâlife effectiveness and safety of SOF/SMV with or without ribavirin (RBV) in a large cohort of cirrhotic patients.
Methods. This collaborative multicentre study included data from 968 patients with cirrhosis infected with HCVâGT1 or 4, treated with SOF/SMV±RBV in 30 centres across Spain between Januaryâ2014 and Decemberâ2015. Demographic, clinical, virological and safety data were analysed.
Results. Overall SVR was 92.3%; the majority of patients were treated with RBV (62%) for 12 weeks (92.4%). No significant differences in SVR were observed between genotypes (GT1a:94.3%; GT1b:91.7%; GT4:91.1%). Those patients with more advanced liver disease (Child B/C, MELDâ„10) or portal hypertension (platelet countâ€100Ă109/L, transient elastographyâ„21 Kpa) showed significantly lower SVR rates (84.4%â91.9%) than patients with less advanced liver disease (93.8%â95.9%, P<.01 in all cases). In the multivariate analysis, the use of RBV, female gender, baseline albuminâ„35 g/L, MELD<10 and lack of exposure to a triple therapy regimen were independent predictors of SVR (P<.05). Serious adverse events (SAEs) and SAEâassociated discontinuation events occurred in 5.9% and 2.6%.
Conclusions. In this large cohort of cirrhotic patients managed in the realâworld setting in Spain, SOF/SMV±RBV yielded to excellent SVR rates, especially in patients with compensated liver cirrhosis. In addition, this combination showed to be safe, with low rates of SAEs and early discontinuations.Instituto de Salud Carlos III; PI15/0015
Novel association of the obesity risk-allele near Fas Apoptotic Inhibitory Molecule 2 (FAIM2) gene with heart rate and study of its effects on myocardial infarction in diabetic participants of the PREDIMED trial
BACKGROUND:
The Fas apoptotic pathway has been implicated in type 2 diabetes and cardiovascular disease. Although a polymorphism (rs7138803; Gâ>âA) near the Fas apoptotic inhibitory molecule 2 (FAIM2) locus has been related to obesity, its association with other cardiovascular risk factors and disease remains uncertain.
METHODS:
We analyzed the association between the FAIM2-rs7138803 polymorphism and obesity, blood pressure and heart rate in 7,161 participants (48.3% with type 2 diabetes) in the PREDIMED study at baseline. We also explored gene-diet interactions with adherence to the Mediterranean diet (MedDiet) and examined the effects of the polymorphism on cardiovascular disease incidence per diabetes status after a median 4.8-year dietary intervention (MedDiet versus control group) follow-up.
RESULTS:
We replicated the association between the FAIM2-rs7138803 polymorphism and greater obesity risk (OR: 1.08; 95% CI: 1.01-1.16; Pâ=â0.011; per-A allele). Moreover, we detected novel associations of this polymorphism with higher diastolic blood pressure (DBP) and heart rate at baseline (Bâ=â1.07; 95% CI: 0.97-1.28 bmp in AA vs G-carriers for the whole population), that remained statistically significant even after adjustment for body mass index (Pâ=â0.012) and correction for multiple comparisons. This association was greater and statistically significant in type-2 diabetic subjects (Bâ=â1.44: 95% CI: 0.23-2.56 bmp; Pâ=â0.010 for AA versus G-carriers). Likewise, these findings were also observed longitudinally over 5-year follow-up. Nevertheless, we found no statistically significant gene-diet interactions with MedDiet for this trait. On analyzing myocardial infarction risk, we detected a nominally significant (Pâ=â0.041) association in type-2 diabetic subjects (HR: 1.86; 95% CI:1.03-3.37 for AA versus G-carriers), although this association did not remain statistically significant following correction for multiple comparisons.
CONCLUSIONS:
We confirmed the FAIM2-rs7138803 relationship with obesity and identified novel and consistent associations with heart rate in particular in type 2 diabetic subjects. Furthermore, our results suggest a possible association of this polymorphism with higher myocardial infarction risk in type-2 diabetic subjects, although this result needs to be replicated as it could represent a false positive
