AbstractStress induces injury in intestinal barrier function in piglets. Long-chain n-3 PUFA have been shown to exhibit potential immunomodulatory and barrier protective effects in animal models and clinical trials. In addition, corticotropin-releasing hormone (CRH)/CRH receptor (CRHR) signalling pathways play an important role in stress-induced alterations of intestinal barrier function. We hypothesised that fish oil could affect intestinal barrier function and CRH/CRHR signalling pathways. In total, thirty-two weaned pigs were allocated to one of four treatments. The experiment consisted of a 2×2 factorial design, and the main factors included immunological challenge (saline or lipopolysaccharide (LPS)) and diet (5 % maize oil or 5 % fish oil). On d 19 of the trial, piglets were treated with saline or LPS. At 4 h after injection, all pigs were killed, and the mesenteric lymph nodes (MLN), liver, spleen and intestinal samples were collected. Fish oil decreased bacterial translocation incidence and the number of translocated micro-organisms in the MLN. Fish oil increased intestinal claudin-1 protein relative concentration and villus height, as well as improved the intestinal morphology. In addition, fish oil supplementation increased intestinal intraepithelial lymphocyte number and prevented elevations in intestinal mast cell and neutrophil numbers induced by LPS challenge. Moreover, fish oil tended to decrease the mRNA expression of intestinal CRHR1, CRH and glucocorticoid receptors. These results suggest that fish oil supplementation improves intestinal barrier function and inhibits CRH/CRHR1 signalling pathway and mast cell tissue density.

Published: April 2016

AbstractIncreased whole-grain (WG) consumption reduces the risk of CVD, type 2 diabetes and some cancers, is related to reduced body weight and weight gain and is related to improved intestinal health. Definitions of ‘WG’ and ‘WG food’ are proposed and used in some countries but are not consistent. Many countries promote WG consumption, but the emphasis given and the messages used vary. We surveyed dietary recommendations of fifty-three countries for mentions of WG to assess the extent, rationale and diversity in emphasis and wording of any recommendations. If present, recommendations were classified as either ‘primary’, where the recommendation was specific for WG, or ‘secondary’, where recommendations were made in order to achieve another (primary) target, most often dietary fibre intake. In total, 127 organisations were screened, including government, non-governmental organisations, charities and professional bodies, the WHO and European Food Safety Authority, of which forty-nine including WHO provide a WG intake recommendation. Recommendations ranged from ‘specific’ with specified target amounts (e.g. x g WG/d), ‘semi-quantitative’ where intake was linked to intake of cereal/carbohydrate foods with proportions of WG suggested (e.g. x servings of cereals of which y servings should be WG) to ‘non-specific’ based on ‘eating more’ WG or ‘choosing WG where possible’. This lack of a harmonised message may result in confusion for the consumer, lessen the impact of public health messages and pose barriers to trade in the food industry. A science-based consensus or expert opinion on WG recommendations is needed, with a global reach to guide public health decision making and increase WG consumption globally.

Published: April 2016

AbstractPeripheral blood mononuclear cells (PBMC) are increasingly used for nutrigenomic studies. In this study, we aimed to identify whether these cells could reflect the development of an obesogenic profile associated with the intake of high-fat (HF) diets. We analysed, by real-time RT-PCR, the dietary response of key genes related to lipid metabolism, obesity and inflammation in PBMC of control rats, rats fed a cafeteria or a commercial HF diet and rats fed a control diet after the intake of a cafeteria diet (post-cafeteria model). Cafeteria diet intake, which resulted in important overweight and related complications, altered the expressions of most of the studied genes in PBMC, evidencing the development of an obesogenic profile. Commercial HF diet, which produced metabolic alterations but in the absence of noticeably increased body weight, also altered PBMC gene expression, inducing a similar regulatory pattern as that observed for the cafeteria diet. Regulation of carnitine palmitoyltransferase I (Cpt1a) mRNA expression was of special interest; its expression reflected metabolic alterations related to the intake of both obesogenic diets (independently of increased body weight) even at an early stage as well as metabolic recovery in post-cafeteria animals. Thus, PBMC constitute an important source of biomarkers that reflect the increased adiposity and metabolic deregulation associated with the intake of HF diets. In particular, we propose an analysis ofCpt1aexpression as a good biomarker to detect the early metabolic alterations caused by the consumption of hyperlipidic diets, and also as a marker of metabolic recovery associated to weight loss.

AbstractThe present study evaluated the effects of dietary microbial phytase on the growth and gut health of hybrid tilapia (Oreochromis niloticus♀×Oreochromis aureus♂), focusing on the effect on intestinal histology, adhesive microbiota and expression of immune-related cytokine genes. Tilapia were fed either control diet or diet supplemented with microbial phytase (1000 U/kg). Each diet was randomly assigned to four groups of fish reared in cages (3×3×2 m). After 12 weeks of feeding, weight gain and feed conversion ratio of tilapia were not significantly improved by dietary microbial phytase supplementation. However, significantly higher level of P content in the scales, tighter and more regular intestinal mucosa folds were observed in the microbial phytase group and the microvilli density was significantly increased. The adhesive gut bacterial communities were strikingly altered by microbial phytase supplementation (0·41<similarity coefficient<0·54). Stimulated intestinal inflammation and stress status were observed in the fish fed diet supplemented with microbial phytase, as indicated by the up-regulated intestinal expressions of the cytokine genes (tnf-αandtgf-β) andhsp70. In addition, the gut microvilli height was significantly decreased in the phytase group. These results indicate that dietary microbial phytase may exert mixed effects on hybrid tilapia, and can guide our future selection of phytases as aquafeed additives – that is, eliminating those that can stimulate intestinal inflammation.

AbstractWe investigated the validity and reproducibility of the FFQ used in the Dutch European Investigation of Cancer and Nutrition cohort, in order to rank subjects according to intakes of fatty acid classes and individual fatty acids. In total, 121 men and women (23–72 years) filled out three FFQ at 6-month intervals between 1991 and 1992. As a reference method, they filled out twelve monthly 24-h dietary recalls (24HDR) during the same year. Intra-class correlation coefficients for the FFQ showed moderate to good reproducibility across all fatty acids (classes and individual) in men (0·56–0·81) and women (0·57–0·83). In men, Spearman’s correlation coefficients (rs) for the FFQ compared with the 24HDR indicated moderate to good relative validity (rs=0·45–0·71) for all fatty acids, except for arachidonic acid and marine PUFA (rs<0·40). In women, relative validity was moderate to good for MUFA andtrans-fatty acids (TFA) and the majority of SFA (rs=0·40–0·66), was fair for the short-chain SFA and lauric acid (rs=0·30–0·33) and was fair to moderate for PUFA (rs=0·22–0·47). Bland–Altman plots showed good agreement between the FFQ and 24HDR, and proportional bias for fatty acids with very low intakes. In conclusion, the FFQ showed good reproducibility for subject ranking based on intakes of fatty acids (classes and individual). The relative validity measures indicated that the FFQ is an adequate tool to rank subjects according to intakes of high-abundant fatty acids, but less for low-abundant fatty acids.

AbstractThe Internet has become a major source of health and nutrition information. Little is known about the type of consulted websites (institutionalv. non-institutional) and the tendency to discuss with a healthcare professional (HCP) the information found on the Internet. The aim of this cross-sectional study was to investigate health- and nutrition-related Internet use in a large French population-based study. Data were collected in 2013 using self-administered, web-based questionnaires from 42 113 participants of the NutriNet-Santé study (mean age=51·2 years, 76 % women). Unconditional multivariate logistic regression analyses andχ2tests were used for comparisons. In total, 85·1 % of the subjects used the Internet to search for health and/or nutrition information, and 23·6 % used the Internet to read or post messages on health/nutrition forums. Only 16·0 % discussed with a HCP the information found online. This proportion was lower in subjects with lower educational level (OR 0·77; 95 % CI 0·72, 0·82) and lower computer skills (OR 0·70; 95 % CI 0·65, 0·76). In total, 8038 health/nutrition websites were cited, with institutional websites representing only 12·9 % of that number. Only one institutional website was present in the top 10. Older subjects (OR 1·49; 95 % CI 1·28–1·74), those with lower educational level (OR 2·08; 95 % CI 1·75, 2·50) and lower nutritional knowledge (OR 1·33; 1·12, 1·59) were more likely to cite non-institutional websites. This large population-based study showed that institutional websites were infrequently accessed and that a few participants discussed the information found online with their HCP. This particular trend was especially visible among individuals who were more vulnerable regarding misleading information. This supports the need to increase awareness of high-quality websites providing reliable health/nutrition information.
Modification of Public Policies by Street-Level Organisations: An Institutional Work Perspective
Authors: BREIT ERIC , ALM ANDREASSEN TONE , SALOMON ROBERT H. 
Published: April 2016

AbstractThe literature on policy implementation is divided with regards to the impact of street-level bureaucrats on the implementation of public policies. In this paper, we aim to add to and nuance these debates by focusing on ‘institutional work’ – i.e. the creation, maintenance and disruption of institutions – undertaken by central authorities and street-level bureaucrats during public reform processes. On the basis of a case study of the organisational implementation of a retirement pension reform in the Norwegian Labor and Welfare Administration, we argue that institutional work is a useful heuristic device for conceptualising the variety of responses available to street-level bureaucrats during public reforms. We also argue that the responses demonstrate the impact of street-level bureaucrats in these reforms in the context of managerial control and regulation. Finally, we argue that the effectiveness of policy change is dependent on the institutional work of street-level bureaucrats and, in particular, on institutional work that supports the institutions created by politicians and public administrations.
How do staff influence the quality of long-term dementia care and the lives of residents? A systematic review of the evidence
Authors: Anderson Katrina , Bird Mike , MacPherson Sarah , Blair Annaliese 
Published: April 2016

ABSTRACTBackground:Research suggests and common sense indicates that there are relationships between staff variables in residential dementia care and the quality of life (QOL) of residents, with poor care due to staff factors increasing resident suffering. Despite these indications, we do not have a coherent picture of these relationships, which variables are important, and where to intervene in order to minimize suffering for people with dementia.Methods:This systematic review examined associations between staff variables, quality of care (QOC), and QOL for residents, using published peer-reviewed literature from the last 20 years. A comprehensive search was conducted using an exhaustive list of search terms, leading to the identification of 33,204 unique papers, which was reduced to 35 on-topic papers.Results:In the main, we were able to provide collective evidence to suggest there are relationships between potentially adjustable staff variables and QOC on to QOL. When staff treat and interact empathetically and humanely in care, there is a relationship with better mood for residents, delayed functional dependence and better food intake. Where staff are more skilled and educated, there is less psychotropic medication use. Unlimited empathy about the risk of residents falling or being in pain is not enough; staff need to know about the dangers of restraint.Conclusions:Confidence in these indicative links is weakened by a lack of high-quality prospective longitudinal studies focusing on potentially adjustable staff variables, with a bias towards cross-sectional studies including only variables that are fixed or unlikely to change.

AbstractPurposeThis study evaluated dosimetric parameters for cervical high-dose-rate (HDR) brachytherapy treatment using varying dose prescription methods.MethodsThis study includes 125 tandem-based cervical HDR brachytherapy treatment plans of 25 patients who received HDR brachytherapy. Delineation of high-risk clinical target volumes (HR-CTVs) and organ at risk were done on original computed tomographic images. The dose prescription point was defined as per International Commission in Radiation Units and Measurements Report Number 38 (ICRU-38), also redefined using American Brachytherapy Society (ABS) 2011 criteria. The coverage index (V100) for each HR-CTV was calculated using dose volume histogram parameters. A plot between HR-CTV and V100was plotted using the best-fit linear regression line (least-square fit analysis).ResultsMean prescribed dose to ICRU-38 Point A was 590·47±28·65 cGy, and to ABS Point A was 593·35±30·42 cGy. There was no statistically significant difference between planned ICRU-38 and calculated ABS Point A doses (p=0·23). The plot between HR-CTV and V100is well defined by the best-fit linear regression line with a correlation coefficient of 0·9519.ConclusionFor cervical HDR brachytherapy, dose prescription to an arbitrarily defined point (e.g., Point A) does not provide consistent coverage of HR-CTV. The difference in coverage between two dose prescription approaches increases with increasing CTV. Our ongoing work evaluates the dosimetric consequences of volumetric dose prescription approaches for these patients.

AbstractPromoting the paracrine effects of human mesenchymal stem cell (hMSC) therapy may contribute to improvements in patient outcomes. Here we develop an innovative strategy to enhance the paracrine effects of hMSCs. In a mouse hindlimb ischaemia model, we examine the effects of hMSCs in which a novel triple-catalytic enzyme is introduced to stably produce prostacyclin (PGI2-hMSCs). We show that PGI2-hMSCs facilitate perfusion recovery and enhance running capability as compared with control hMSCs or iloprost (a stable PGI2analogue). Transplanted PGI2-hMSCs do not incorporate long term into host tissue, but rather they mediate host regeneration and muscle mass gain in a paracrine manner. Mechanistically, this involves long noncoding RNA H19 in promoting PGI2-hMSC-associated survival and proliferation of host progenitor cells under hypoxic conditions. Together, our data reveal the novel ability of PGI2-hMSCs to stimulate host regenerative processes and improve physical function by regulating long noncoding RNA in resident progenitor cells.

Published: April 2016

AbstractThe species variability and potential environmental functions of Taxus rhizosphere microbial community were studied by comparative analyses of 15 16S rRNA and 15 ITS MiSeq sequencing libraries from Taxus rhizospheres in subtropical and temperate regions of China, as well as by isolating laccase-producing strains and polycyclic aromatic hydrocarbon (PAH)-degrading strains. Total reads could be assigned to 2,141 Operational Taxonomic Units (OTUs) belonging to 31 bacteria phyla and 2,904 OTUs of at least seven fungi phyla. The abundance of Planctomycetes, Actinobacteria and Chloroflexi was higher in T. cuspidata var. nana and T. × media rhizospheres than in T. mairei rhizosphere (NF), while Acidobacteria, Proteobacteria, Nitrospirae and unclassified bacteria were more abundant in the latter. Ascomycota and Zygomycota were predominant in NF, while two temperate Taxus rhizospheres had more unclassified fungi, Basidiomycota and Chytridiomycota. The bacterial/fungal community richness and diversity were lower in NF than in other two. Three dye decolorizing fungal isolates were shown to be highly efficient in removing three classes of reactive dye, while two PAH-degrading fungi were able to degrade recalcitrant benzo[a]pyrene. The present studies extend the knowledge pedigree of the microbial diversity populating rhizospheres and exemplify the method shift in research and development of resource plant rhizosphere.

AbstractAvian influenza viruses present an emerging epidemiological concern as some strains of H5N1 avian influenza can cause severe infections in humans with lethality rates of up to 60%. These have been in circulation since 1997 and recently a novel H7N9-subtyped virus has been causing epizootics in China with lethality rates around 20%. To better understand the replication kinetics of these viruses, we combined several extensive viral kinetics experiments with mathematical modelling ofin vitroinfections in human A549 cells. We extracted fundamental replication parameters revealing that, while both the H5N1 and H7N9 viruses replicate faster and to higher titers than two low-pathogenicity H1N1 strains, they accomplish this via different mechanisms. While the H7N9 virions exhibit a faster rate of infection, the H5N1 virions are produced at a higher rate. Of the two H1N1 strains studied, the 2009 pandemic H1N1 strain exhibits the longest eclipse phase, possibly indicative of a less effective neuraminidase activity, but causes infection more rapidly than the seasonal strain. This explains, in part, the pandemic strain’s generally slower growth kinetics and permissiveness to accept mutations causing neuraminidase inhibitor resistance without significant loss in fitness. Our results highlight differential growth properties of H1N1, H5N1 and H7N9 influenza viruses.

AbstractCD4+CD25+FoxP3+ regulatory T cells (Tregs) are exploited by mycobacteria to subvert the protective host immune responses. The Treg expansion in the periphery requires signaling by professional antigen presenting cells and in particularly dendritic cells (DC). However, precise molecular mechanisms by which mycobacteria instruct Treg expansion via DCs are not established. Here we demonstrate that mycobacteria-responsive sonic hedgehog (SHH) signaling in human DCs leads to programmed death ligand-1 (PD-L1) expression and cyclooxygenase (COX)-2-catalyzed prostaglandin E2 (PGE2) that orchestrate mycobacterial infection-induced expansion of Tregs. While SHH-responsive transcription factor GLI1 directly arbitrated COX-2 transcription, specific microRNAs, miR-324-5p and miR-338-5p, which target PD-L1 were downregulated by SHH signaling. Further, counter-regulatory roles of SHH and NOTCH1 signaling during mycobacterial-infection of human DCs was also evident. Together, our results establish that Mycobacterium directs a fine-balance of host signaling pathways and molecular regulators in human DCs to expand Tregs that favour immune evasion of the pathogen.
