Associations between fruit and vegetable consumption and psychological distress: results from a population-based study.

BACKGROUND: Several studies observed associations of various aspects of diet with mental health, but little is known about the relationship between following the 5-a-day recommendation for fruit and vegetables consumption and mental health. Thus, we examined the associations of the Swiss daily recommended fruit and vegetable intake with psychological distress. METHODS: Data from 20,220 individuals aged 15+ years from the 2012 Swiss Health Survey were analyzed. The recommended portions of fruit and vegetables per day were defined as 5-a-day (at least 2 portions of fruit and 3 of vegetables). The outcome was perceived psychological distress over the previous 4 weeks (measured by the 5-item mental health index [MHI-5]). High distress (MHI-5 score ≤ 52), moderate distress (MHI-5 > 52 and ≤ 72) and low distress (MHI-5 > 72 and ≤ 100) were differentiated and multinomial logistic regression analyses adjusted for known confounding factors were performed. RESULTS: The 5-a-day recommendation was met by 11.6 % of the participants with low distress, 9.3 % of those with moderate distress, and 6.2 % of those with high distress. Consumers fulfilling the 5-a-day recommendation had lower odds of being highly or moderately distressed than individuals consuming less fruit and vegetables (moderate vs. low distress: OR = 0.82, 95 % confidence interval [CI] 0.69-0.97; high vs. low distress: OR = 0.55, 95 % CI 0.41-0.75). CONCLUSIONS: Daily intake of 5 servings of fruit and vegetable was associated with lower psychological distress. Longitudinal studies are needed to further determine the causal nature of this relationship.

Gut physiology mediates a trade-off between adaptation to malnutrition and susceptibility to food-borne pathogens.

The animal gut plays a central role in tackling two common ecological challenges, nutrient shortage and food-borne parasites, the former by efficient digestion and nutrient absorption, the latter by acting as an immune organ and a barrier. It remains unknown whether these functions can be independently optimised by evolution, or whether they interfere with each other. We report that Drosophila melanogaster populations adapted during 160 generations of experimental evolution to chronic larval malnutrition became more susceptible to intestinal infection with the opportunistic bacterial pathogen Pseudomonas entomophila. However, they do not show suppressed immune response or higher bacterial loads. Rather, their increased susceptibility to P. entomophila is largely mediated by an elevated predisposition to loss of intestinal barrier integrity upon infection. These results may reflect a trade-off between the efficiency of nutrient extraction from poor food and the protective function of the gut, in particular its tolerance to pathogen-induced damage.

Strategy Formulation and Implementation Case of High Tech Instruments

The strategy process is a method for strategy formulation and implementation. The strategy process is commonly used especially within bigger companies. It is important to link the strategy formulation and implementation. The objective of this thesis has been to find out improvement areas for the case company’s strategy process. The theoretical framework based on literature emphasizes on strategy process as a method for strategy formulation and implementation. The theoretical framework, several mainly ad hoc interviews and author’s observation were used as tools to analyze the case company’s strategy process. The hierarchy in between the various corporate levels provides the foundation to formulate and implement the strategies. These strategies include the corporate and strategic business area level strategies. The recommendations to improve the case company’s strategy process were formulated at corporate and strategic business area levels. These recommendations were formulated based on research and experience gained throughout the work. The role of strategic projects to implement the strategies more efficiently and organizational control over distribution were found as potential improvement areas. The resource allocation prioritizing towards the most important strategic projects was also an important improvement area.

Measuring individuals' response quality in self-administered psychological tests : an introduction to Gendre's functional method

The functional method is a new test theory using a new scoring method that assumes complexity in test structure, and thus takes into account every correlation between factors and items. The main specificity of the functional method is to model test scores by multiple regression instead of estimating them by using simplistic sums of points. In order to proceed, the functional method requires the creation of hyperspherical measurement space, in which item responses are expressed by their correlation with orthogonal factors. This method has three main qualities. First, measures are expressed in the absolute metric of correlations; therefore, items, scales and persons are expressed in the same measurement space using the same single metric. Second, factors are systematically orthogonal and without errors, which is optimal in order to predict other outcomes. Such predictions can be performed to estimate how one would answer to other tests, or even to model one's response strategy if it was perfectly coherent. Third, the functional method provides measures of individuals' response validity (i.e., control indices). Herein, we propose a standard procedure in order to identify whether test results are interpretable and to exclude invalid results caused by various response biases based on control indices.

Testing Local Adaptation in a Natural Great Tit-Malaria System: An Experimental Approach.

Finding out whether Plasmodium spp. are coevolving with their vertebrate hosts is of both theoretical and applied interest and can influence our understanding of the effects and dynamics of malaria infection. In this study, we tested for local adaptation as a signature of coevolution between malaria blood parasites, Plasmodium spp. and its host, the great tit, Parus major. We conducted a reciprocal transplant experiment of birds in the field, where we exposed birds from two populations to Plasmodium parasites. This experimental set-up also provided a unique opportunity to study the natural history of malaria infection in the wild and to assess the effects of primary malaria infection on juvenile birds. We present three main findings: i) there was no support for local adaptation; ii) there was a male-biased infection rate; iii) infection occurred towards the end of the summer and differed between sites. There were also site-specific effects of malaria infection on the hosts. Taken together, we present one of the few experimental studies of parasite-host local adaptation in a natural malaria system, and our results shed light on the effects of avian malaria infection in the wild.

Literature report : a review of policy learning in five strands of political science research

This paper reviews the policy learning literature in political science. In recent years, the number of publications on learning in the political realm increased dramatically. Researchers have focused on how policymakers and administrators adapt policies based on learning processes or experiences. Thereby, learning has been discussed in very different ways. Authors have referred to learning in the context of ideas, understood as deeply held beliefs, and, as change and adaptation of policy instruments. Two other strands of literature have taken into consideration learning, namely the diffusion literature and research on transfer, which put forward learning to understand who learns from whom and what. Opposed to these views, political learning emphasizes the adaptation of new strategies by policymakers over the transfer of knowledge or broad ideas. In this approach, learning occurs due to the failure of existing policies, increasing problem pressure, scientific innovations, or a combination of these elements.

Guideline adaptation: a methodology to enhance efficiency in guideline development and improve utilization.

BACKGROUND: Developing and updating high-quality guidelines requires substantial time and resources. To reduce duplication of effort and enhance efficiency, we developed a process for guideline adaptation and assessed initial perceptions of its feasibility and usefulness. METHODS: Based on preliminary developments and empirical studies, a series of meetings with guideline experts were organised to define a process for guideline adaptation (ADAPTE) and to develop a manual and a toolkit made available on a website (http://www.adapte.org). Potential users, guideline developers and implementers, were invited to register and to complete a questionnaire evaluating their perception about the proposed process.

Combining niche modelling and landscape genetics to study local adaptation: A novel approach illustrated using alpine plants

Understanding the factors that shape adaptive genetic variation across species niches has become of paramount importance in evolutionary ecology, especially to understand how adaptation to changing climate affects the geographic range of species. The distribution of adaptive alleles in the ecological niche is determined by the emergence of novel mutations, their fitness consequences and gene flow that connects populations across species niches. Striking demographical differences and source sink dynamics of populations between the centre and the margin of the niche can play a major role in the emergence and spread of adaptive alleles. Although some theoretical predictions have long been proposed, the origin and distribution of adaptive alleles within species niches remain untested. In this paper, we propose and discuss a novel empirical approach that combines landscape genetics with species niche modelling, to test whether alleles that confer local adaptation are more likely to occur in either marginal or central populations of species niches. We illustrate this new approach by using a published data set of 21 alpine plant species genotyped with a total of 2483 amplified fragment length polymorphisms (AFLP), distributed over more than 1733 sampling sites across the Alps. Based on the assumption that alleles that were statistically associated with environmental variables were adaptive, we found that adaptive alleles in the margin of a species niche were also present in the niche centre, which suggests that adaptation originates in the niche centre. These findings corroborate models of species range evolution, in which the centre of the niche contributes to the emergence of novel adaptive alleles, which diffuse towards niche margins and facilitate niche and range expansion through subsequent local adaptation. Although these results need to be confirmed via fitness measurements in natural populations and functionally characterised genetic sequences, this study provides a first step towards understanding how adaptive genetic variation emerges and shapes species niches and geographic ranges along environmental gradients.

Reactive Recruitment of Attentional Control in Math Anxiety: An ERP Study of Numeric Conflict Monitoring and Adaptation

This study uses event-related brain potentials (ERPs) to investigate the electrophysiological correlates of numeric conflict monitoring in math-anxious individuals, by analyzing whether math anxiety is related to abnormal processing in early conflict detection (as shown by the N450 component) and/or in a later, response-related stage of processing (as shown by the conflict sustained potential; Conflict-SP). Conflict adaptation effects were also studied by analyzing the effect of the previous trial"s congruence in current interference. To this end, 17 low math-anxious (LMA)and 17 high math-anxious (HMA) individuals were presented with a numerical Stroop task. Groups were extreme in math anxiety but did not differ in trait or state anxiety or in simple math ability. The interference effect of the current trial (incongruent-congruent) and the interference effect preceded by congruence and by incongruity were analyzed both for behavioral measures and for ERPs. A greater interference effect was found for response times in the HMA group than in the LMA one. Regarding ERPs, the LMA group showed a greater N450 component for the interference effect preceded by congruence than when preceded by incongruity, while the HMA group showed greater Conflict-SP amplitude for the interference effect preceded by congruence than when preceded by incongruity. Our study showed that the electrophysiological correlates of numeric interference in HMA individuals comprise the absence of a conflict adaptation effect in the first stage of conflict processing (N450) and an abnormal subsequent up-regulation of cognitive control in order to overcome the conflict (Conflict-SP). More concretely, our study shows that math anxiety is related to a reactive and compensatory recruitment of control resources that is implemented only when previously exposed to a stimuli presenting conflicting information

Les critères STOPP/START.v2 : adaptation en langue française. [STOPP/START.v2 criteria: Adaptation into French language]

Objectif STOPP/START est un outil de détection de la prescription médicamenteuse potentiellement inappropriée chez la personne de 65 ans ou plus. La version initiale de 2008 vient d'être mise à jour et améliorée par ses auteurs. Nous en présentons l'adaptation et la validation en langue française. Méthodes L'adaptation en français de l'outil STOPP/START.v2 a été réalisée par deux experts, confirmée par la méthode de traduction-inverse, et finalisée d'après les commentaires de neufs évaluateurs francophones, gériatres, pharmaciens cliniciens, et médecin généraliste de quatre pays (France, Belgique, Suisse, Canada). La validation a été complétée par une analyse de concordance inter-juge (CCI) des critères STOPP/START.v2 appliqués à dix vignettes cliniques standardisées. Résultats Les 115 critères de STOPP/START.v2 en français sont, par rapport à la version originale anglaise, identiques par leur classification mais adaptés en termes de présentation (critères START.v2 commençant par la condition clinique, et accompagnés par une justification du caractère inapproprié de l'omission) voire de formulation de certains critères. Cette adaptation en français est validée par (i) la traduction-inverse montrant le respect du sens clinique de la version originale, (ii) l'identification semblable des critères lorsque appliqués à dix vignettes cliniques par les neuf évaluateurs, et (iii) le haut niveau de concordance de ces neuf évaluations tant pour STOPP.v2 (CCI 0,849) que pour START.v2 (CCI 0,921). Conclusion L'adaptation en langue française des critères STOPP/START.v2 fournit aux cliniciens un outil de détection de la prescription médicamenteuse potentiellement inappropriée chez les personnes de 65 ans et plus qui est logique, fiable et facile à utiliser. Objective STOPP/START is a screening tool to detect potentially inappropriate prescribing in persons aged 65 or older. Its Irish authors recently updated and improved the initially published version of 2008. We present the adaptation and validation into French language of this updated tool. Methods STOPP/START.v2 was adapted into French by two experts, then confirmed by a translation-back translation method and finalised according to the comments of nine French-speaking assessors - geriatricians, pharmacologists and a general physician - from four countries (France, Belgium, Switzerland, and Canada). The validation was completed by an inter-rater reliability (IRR) analysis of the STOPP/START.v2 criteria applied to 10 standardized clinical vignettes. Results In comparison to the original English version, the 115 STOPP/START.v2 criteria in French language classify in identical manner, but the presentation has been adjusted (START.v2 first specifies the clinical condition followed by an explanation of the inappropriateness of the prescription or omission). This adaptation into French language was validated by means of (i) the translation/back-translation, which showed that the French version complied with the clinical meaning of the original criteria; (ii) the similar screening results when applied by the nine specialists to the 10 cases; and (iii) the high level of inter-rater reliability of these 9 evaluations, for both STOPP (IRR 0.849) and START.v2 (IRR 0.921). Conclusion The adaptation into French of the STOPP/START.v2 criteria provides clinicians with a screening tool to detect potentially inappropriate prescribing in patients aged 65 and older that is more logical, more reliable and easier to use.

Adaptation of a Gaussia princeps Luciferase reporter system in Candida albicans for in vivo detection in the Galleria mellonella infection model.

For the past 10 years, mini-host models and in particular the greater wax moth Galleria mellonella have tended to become a surrogate for murine models of fungal infection mainly due to cost, ethical constraints and ease of use. Thus, methods to better assess the fungal pathogenesis in G. mellonella need to be developed. In this study, we implemented the detection of Candida albicans cells expressing the Gaussia princeps luciferase in its cell wall in infected larvae of G. mellonella. We demonstrated that detection and quantification of luminescence in the pulp of infected larvae is a reliable method to perform drug efficacy and C. albicans virulence assays as compared to fungal burden assay. Since the linearity of the bioluminescent signal, as compared to the CFU counts, has a correlation of R(2) = 0.62 and that this method is twice faster and less labor intensive than classical fungal burden assays, it could be applied to large scale studies. We next visualized and followed C. albicans infection in living G. mellonella larvae using a non-toxic and water-soluble coelenterazine formulation and a CCD camera that is commonly used for chemoluminescence signal detection. This work allowed us to follow for the first time C. albicans course of infection in G. mellonella during 4 days.

Étude descriptive et corrélationnelle de l'ajustement psychosocial de la personne âgée au diabète de type 2

Problématique. Le diabete de type 2 est la maladie metabolique la plus frequente, sa prevalence ne cesse de croitre et parallelement, la population vieillissante est en constante augmentation. Le diagnostic de diabete de type 2 accroit le risque de syndrome geriatrique. Pour prevenir d'eventuelles complications, le traitement du diabete de type 2 est constitue de differentes composantes incluant des automesures de la glycemie capillaire, une prise reguliere du traitement pharmacologique souvent multiples de l'activite physique et enfin le suivi de recommandations pour une alimentation equilibree. Pour la personne agee diabetique de type 2, l'apprentissage de l'application de ces composantes du traitement signifie qu'elle doit proceder a des ajustements dans sa vie quotidienne. Buts. Les buts de cette etude sont : 1) de decrire l'ajustement psychosocial de la personne agee au diabete de type 2, et 2) d'explorer la presence de relations entre differentes variables sociodemographiques et de sante et l'ajustement psychosocial de personnes agees diabetiques de type 2. Méthodologie. Il s'agit d'une etude descriptive correlationnelle. L'echantillon de convenance est compose de 57 participants ages de plus de 65 ans connus pour un diagnostic de diabete de type 2. Les mesures ont ete effectuees par l'utilisation du questionnaire « The Psychological Adjustement to Illness Scale (PAIS-SR) » developpe par Derogatis (1986). Les donnees ont ete recoltees dans un centre ambulatoire universitaire de consultation en diabetologie en Suisse Romande. La théorie de l'adaptation cognitive lors d'événements menaçants (Taylor, 1983) a servi de cadre theorique a l'etude. Résultats. La majorite des participants a l'etude est de sexe masculin et l'age moyen des participants a l'etude est de 71 ans. Les participants ont un ajustement psychosocial a la maladie positif. Le score des signes depressifs est faible, tandis que davantage de difficultes apparaissent dans le domaine des relations sexuelles. Tous les participants ont des comorbidites ou ont developpe des complications. La moyenne de l'hemoglobine glyquee (HbA1c) correspond aux normes preconisees par les experts. Aucune correlation significative n'a pu etre etablie entre le niveau d'ajustement psychosocial, et les variables sociodemographiques et de sante.Conclusion : Les participants a l'etude ont un controle glycemique optimal et presentent un ajustement psychosocial positif. Malgre le fait qu'aucune correlation n'a pu etre determinee entre les differentes variables, la problematique reste importante a etudier. Les complications et les comorbidites associees au diagnostic de diabete de type 2 rendent cette population particulierement vulnerable, et a risque de declin fonctionnel. Peu d'etudes ont permis de determiner les composantes favorisant le processus d'adaptation d'un etat de sante vers un etat de maladie, et ce dans un contexte de vieillissement. La recherche dans ce domaine permettrait de determiner plus precisement des axes de prise en charge et de favoriser la prevention du declin fonctionnel.
