Cardiovascular health and wellbeing in Northern Ireland - Literature review

The PHA, supported by the Institute of Public Health in Ireland (IPH) and other agencies and individuals, has completed a health impact assessment (HIA) on the Cardiovascular Service Framework (CVSFW) for Northern Ireland.The CVSFW is the first in a series of service frameworks developed in Northern Ireland to guide HSC provision from prevention and health improvement over early intervention in communities and general practice into hospital and other institutional settings towards rehabilitation, palliative care and end of life.The CVSFW is relevant to everyone who has a part in HSC services for health improvement, hypertension, hyperlipidaemia, diabetes, heart disease, cerebrovascular disease (stroke), peripheral vascular disease and renal disease. This includes patients, carers, families, communities, voluntary and statutory service providers, policy makers and researchers.

What's in your Chinese Takeaway?

The impact that food prepared outside of the home has on the nutrient intakes of adults, has beenstudied previously on the IOI. It was found that food prepared outside the home contains considerably more dietary fat than food prepared within the home and it is also lower in fibre and micronutrients. safefood has commissioned previous nutritional surveys in the takeaway sector.These surveys revealed that certain foods i.e. potato, chicken, pizzas and burgers prepared outside thehome are high in calories, fat and salt. These surveys also reported that there are majordifferences in portion sizes across takeaway outlets on the IOI. Traditional Asian diets are low in fat and high in fruit, vegetables and fibre. However, thesetraditional meals have been adapted to suit Western palates and, in doing so, different ingredients indifferent quantities are added, possibly increasing their fat and salt content. Recent research hasfound that Chinese is the single most popular style of meal across both takeaways and restaurants(excluding pub restaurants) on the IOI. Given the diversity of Chinese dishes available, this surveywas designed to provide an insight into the energy (calorie), total fat, saturated fat, protein and saltcontent of a range of Chinese meals from various Chinese takeaways, and Chinese restaurants with atakeaway service.

Intérêt des faibles doses de rt-PA dans les syndromes inflammatoires et hémorragiques du segment antérieur: étude clinique et revue de la littérature [Treatment of anterior segment fibrinous reactions and hemorrhage with intracameral low dose rt-PA: clinical study and review of the literature].

PURPOSE: to evaluate the efficacy and the safety of low dose intraocular tissue plasminogen activator (rt-PA) in the treatment of traumatic hyphema and postoperative fibrinous membrane. METHODS: Six microg to 10 microg of rt-PA was injected into the anterior chamber to treat severe fibrinous postoperative membranes and total traumatic hyphemae. RESULTS: Thirteen eyes of 13 patients were treated. Four cases of traumatic hyphema and 9 cases of fibrinous membranes were included. Complete fibrinolysis within 24 hours was observed in 4 cases (30.8%). A partial success was noted in 7 eyes (53.8%). No beneficial effect was observed in two cases of traumatic hyphema associated with intravitreal hemorrhage after penetrating trauma. No side effect attributable to rt-PA occurred. CONCLUSION: Low dose intraocular rt-PA appears to be safe and effective in the treatment of postoperative fibrinous membrane and endocular hemorrhage limited to the anterior chamber.

A Review of Harm Reduction Approaches in Ireland and Evidence from the International Literature

This report examines international literature on harm reduction and also presents primary research in health services in Ireland on approaches to harm reduction. The aim of harm reduction efforts is to minimise the risks stemming from shared use of drug-use paraphernalia, such as needle exchange programmes. One of the criticisms of Irish drug services is that the restricted opening hours and limited number of exchange services may contribute to continued sharing of needles among drug users. The report points out that other non-injecting paraphernalia such as spoons are also associated with the risk of contracting diseases, yet services do not as yet focus on them. The report notes that specific risk factors that contribute to risky drug practices include youth, a shorter injecting history, confinement to prison, homelessness and being involved in a sexual relationship with another intravenous drug user. The report suggests that harm reduction practices can be introduced into a prison population without a subsequent increase in drug consumption rates. The provision of consumption rooms and the prescription of heroin are also discussed, with the report noting that legislation would have to altered to implement these new strategies.This resource was contributed by The National Documentation Centre on Drug Use.

Social support group interventions in people with dementia and mild cognitive impairment: a systematic review of the literature

Abstract Despite the large number of studies evaluating social support groups for people with dementia, there are no systematic reviews of current evidence.The aim of this study was to evaluate the effectiveness of social support group interventions for people with dementia and mild cognitive impairment.A systematic review was performed. We searched electronic databases for randomised controlled trials. Two reviewers worked independently to select trials, extract data and assess risk of bias. A total of 546 studies were identified of which two met the inclusion criteria. We were not able to pool data for further analyses, as the interventions tested in the studies meeting the inclusion criteria were too dissimilar in content.The first trial (n = 136) showed a benefit of early-stage memory loss social support groups for depression and quality of life in people with dementia.The second trial (n = 33) showed that post-treatment self-reported self-esteem was higher in the group receiving a multicomponent intervention of social support compared with that in the no intervention control group.Limited data from two studies suggest that support groups may be of psychological benefit to people with dementia by reducing depression and improving quality of life and self-esteem.These findings need to be viewed in light of the small number, small sample size and heterogeneous characteristics of current trials, indicating that it is difficult to draw any conclusions. More multicentre randomised controlled trials in social support group interventions for people with dementia are needed.������������

Characterization of root apoplastic barriers in Arabidopsis thaliana

In vascular plants, the best-known feature of a differentiated endodermal cell is the "Casparian Strip" (CS). This structure refers to a highly localized cell wall impregnation in the transversal and anticlinal walls of the cell, which surrounds the cell like a belt/ring and is tightly coordinated with respect to neighboring cells. Analogous to tight junctions in animal epithelia, CS in plants act as a diffusion barrier that controls the movement of water and ions from soil into the stele. Since its first description by Robert Caspary in 1865 there have been many attempts to identify the chemical nature of the cell wall deposition in CS. Suberin, lignin, or both have been claimed to be the important components of CS in a series of different species. However, the exact chemical composition of CS has remained enigmatic. This controversy was due to the confusion and lack of knowledge regarding the precise measurement of three developmental stages of the endodermis. The CS represent only the primary stage of endodermal differentiation, which is followed by the deposition of suberin lamellae all around the cellular surface of endodermal cells (secondary developmental stage). Therefore, chemical analysis of whole roots, or even of isolated endodermal tissues, will always find both of the polymers present. It was crucial to clarify this point because this will guide our efforts to understand which cell wall biosynthetic component becomes localized in order to form the CS. The main aim of my work was to find out the major components of (early) CS, as well as their spatial and temporal development, physiological roles and relationship to barrier formation. Employing the knowledge and tools that have been accumulated over the last few years in the model plant Arabidopsis thaliana, various histological and chemical assays were used in this study. A particular feature of my work was to completely degrade, or inhibit formation of lignin and suberin biopolymers by biochemical, classical genetic and molecular approaches and to investigate its effect on CS formation and the establishment of a functional diffusion barrier. Strikingly, interference with monolignol biosynthesis abrogates CS formation and delays the formation of function diffusion barrier. In contrast, transgenic plants devoid of any detectable suberin still develop a functional CS. The combination of all these assays clearly demonstrates that the early CS polymer is made from monolignol (lignin monomers) and is composed of lignin. By contrast, suberin is formed much later as a secondary wall during development of endodermis. These early CS are functionally sufficient to block extracellular diffusion and suberin does not play important role in the establishment of early endodermal diffusion barrier. Moreover, suberin biosynthetic machinery is not present at the time of CS formation. Our study finally concludes the long-standing debate about the chemical nature of CS and opens the door to a new approach in lignin research, specifically for the identification of the components of the CS biosynthetic pathway that mediates the localized deposition of cell walls. I also made some efforts to understand the patterning and differentiation of endodermal passage cells in young roots. In the literature, passage cells are defined as a non- suberized xylem pole associated endodermal cells. Since these cells only contain the CS but not the suberin lamellae, it has been assumed that these cells may offer a continued low-resistance pathway for water and minerals into the stele. Thus far, no genes have been found to be expressed specifically in passage cells. In order to understand the patterning, differentiation, and physiological role of passage it would be crucial to identify some genes that are exclusively expressed in these cells. In order to identify such genes, I first generated fluorescent marker lines of stele-expressed transporters that have been reported to be expressed in the passage cells. My aim was to first highlight the passage cells in a non-specific way. In order to find passage cell specific genes I then adapted a two-component system based on previously published methods for gene expression profiling of individual cell types. This approach will allow us to target only the passage cells and then to study gene expression specifically in this cell type. Taken together, this preparatory work will provide an entry point to understand the formation and role of endodermal passage cells. - Chez les plantes vasculaires, la caractéristique la plus commune des cellules différentiées de l'endoderme est la présence de cadres de Caspary. Cette structure correspond à une imprégnation localisée des parties transversales et anticlinales de la paroi cellulaire. Cela donne naissance, autour de la cellule, à un anneau/cadre qui est coordonné par rapport aux cellules voisines. De manière analogue aux jonctions serrées des épithéliums chez les animaux, les cadres de Caspary agissent chez les plantes comme barrière de diffusion, contrôlant le mouvement de l'eau et des ions à travers la racine entre le sol et la stèle. Depuis leur première description par Robert Caspary en 1865, beaucoup de tentatives ont eu pour but de définir la nature chimique de ces cadres de Caspary. Après l'étude de différentes espèces végétales, à la fois la subérine, la lignine ou les deux ont été revendiquées comme étant des composants importants de ces cadres. Malgré tout, leur nature chimique exacte est restée longtemps énigmatique. Cette controverse provient de la confusion et du manque de connaissance concernant la détermination précise des trois stades de développement de l'endoderme. Les cadres de Caspary représentent uniquement le stade primaire de différentiation de l'endoderme. Celui-ci est suivi par le second stade de différentiation, la déposition de lamelles de subérine tout autour de la cellule endodermal. De ce fait, l'analyse chimique de racines entières ou de cellules d'endoderme isolées ne permet pas de séparer les stades de différentiation primaire et secondaire et aboutit donc à la présence des deux polymères. Il est également crucial de clarifier ce point dans le but de connaître quelle machinerie cellulaire localisée à la paroi cellulaire permet l'élaboration des cadres de Caspary. En utilisant les connaissances et les outils accumulés récemment grâce à la plante modèle Arabidopsis thaliana, divers techniques histologiques et chimiques ont été utilisées dans cette étude. Un point particulier de mon travail a été de dégrader ou d'inhiber complètement la formation de lignine ou de subérine en utilisant des approches de génétique classique ou moléculaire. Le but étant d'observer l'effet de l'absence d'un de ces deux polymères sur la formation des cadres de Caspary et l'établissement d'une barrière de diffusion fonctionnelle. De manière frappante, le fait d'interférer avec la voie de biosynthèse de monolignol (monomères de lignine) abolit la formation des cadres de Caspary et retarde l'élaboration d'une barrière de diffusion fonctionnelle. Par contre, des plantes transgéniques dépourvues d'une quantité détectable de subérine sont quant à elles toujours capables de développer des cadres de Caspary fonctionnels. Mises en commun, ces expériences démontrent que le polymère formant les cadres de Caspary dans la partie jeune de la racine est fait de monolignol, et que de ce fait il s'agit de lignine. La subérine, quant à elle, est formée bien plus tard durant le développement de l'endoderme, de plus il s'agit d'une modification de la paroi secondaire. Ces cadres de Caspary précoces faits de lignine suffisent donc à bloquer la diffusion extracellulaire, contrairement à la subérine. De plus, la machinerie de biosynthèse de la subérine n'est pas encore présente au moment de la formation des cadres de Caspary. Notre étude permet donc de mettre un terme au long débat concernant la nature chimique des cadres de Caspary. De plus, elle ouvre la porte à de nouvelles approches dans la recherche sur la lignine, plus particulièrement pour identifier des composants permettant la déposition localisée de ce polymère dans la paroi cellulaire. J'ai aussi fais des efforts pour mettre en évidence la formation ainsi que le rôle des cellules de passage dans les jeunes racines. Dans la littérature, les cellules de passage sont définies comme de la cellule endodermal faisant face aux pôles xylèmes et dont la paroi n'est pas subérisée. Du fait que ces cellules contiennent uniquement des cadres de Caspary et pas de lamelle de subérine, il a été supposé qu'elles ne devraient offrir que peu de résistance au passage de l'eau et des nutriments entre le sol et la stèle. Le rôle de ces cellules de passage est toujours loin d'être clair, de plus aucun gène s'exprimant spécifiquement dans ces cellules n'a été découvert à ce jour. De manière à identifier de tels gènes, j'ai tout d'abord généré des marqueurs fluorescents pour des transporteurs exprimés dans la stèle mais dont l'expression avait également été signalée dans l'endoderme, uniquement dans les cellules de passage. J'ai ensuite développé un système à deux composants basé sur des méthodes déjà publiées, visant principalement à étudier le profil d'expression génique dans un type cellulaire donné. En recoupant les gènes exprimés spécifiquement dans l'endoderme à ceux exprimés dans la stèle et les cellules de passage, il nous sera possible d'identifier le transriptome spécifique de ces cellules. Pris dans leur ensemble, ces résultats devraient donner un bon point d'entrée dans la définition et la compréhension des cellules de passage.

Traumatic mitral valve injury after blunt chest trauma: a case report and review of the literature.

Mitral valve injury after blunt chest trauma is a rare occurrence. We recently admitted a patient with severe traumatic mitral regurgitation who was successfully treated with surgery. Review of the literature aimed at taking an inventory of cases of traumatic nonpenetrating mitral insufficiency that were operated on, since the earliest report in 1964. Eighty-two cases were found and analyzed allowing for a better understanding of the epidemiology, etiology, natural history, pathology, and treatment of this rare condition. The most common lesions reach the papillary muscles (PM), followed by the chordae and then the mitral valve leaflets. Among the 82 cases reported that have been treated with surgery, 57% required a valve replacement. More than half of the patients had a PM injury with a complete or partial rupture. When the rupture is complete, and especially when it involves the anterior PM, the clinical picture is most always acute with clinically important hemodynamic repercussions, often necessitating emergency surgery, most of the time with mitral valve replacement. One must always suspect traumatic mitral injury after blunt chest trauma. The most common mitral lesions affect the PM. The clinical course can be indolent or devastating, and most often requires urgent or delayed surgical treatment, either with mitral valve repair or replacement.

A mi què m'expliques?

Els alumnes i les alumnes de primer cicle d'ESO s'enfronten amb les dificultats de la nova etapa i la necessitat de demostrar les seves competències lingüístiques, quant al redactat i la correcció en l'elaboració de textos diversos. Les noves tecnologies de la informació i la comunicació poden ajudar (i han de propiciar-ho) a desenvolupar aquestes capacitats, i han de ser un element motivador perquè els nois i les noies sentin la necessitat de crear produccions escrites pròpies, adequades lingüísticament, coherents i amb les idees ben organitzades.És necessari, a més, que l'avaluació d'aquestes tasques els serveixi per millorar l'expressió en llengua catalana, gramaticalment i ortogràficament, tot ajudant-los a establir sistemes d'autocorrecció i rectificació d'errors.L'exposició pública (en un mitjà com el d'internet) de les seves obres hauria de reblar l'aspecte de la motivació en la creació d'escrits, de manera que els aporti noves expectatives de comunicació i els animi a participar de l'espai virtual que els ofereix aquesta finestra oberta al món. El meu treball té la intenció de ser un projecte educatiu per aconseguir una millora en l'expressió escrita dels alumnes del primer curs d'ESO amb l'ajuda de les eines de les Tecnologies de la Informació i la Comunicació.

Joan Ramis i La nouvelle Héloïse de Rousseau : una lectura rousseauniana de l'obra dramàtica de Ramis

Aquest estudi es proposa estudiar els vincles que hi ha entre La nouvelle Héloïse (1761) de Jean-Jacques Rousseau i l'obra dramàtica de Joan Ramis i Ramis, especialment la seva Lucrècia (1769), tot i les dificultats que la recepció de Rousseau va tenir en la Menorca il·lustrada. En aquest sentit, el gruix del treball es dedica als elements que tenen en comú les obres de referència, pel que fa al tractament literari dels temes centrals, com ara el que vehicula la sensibilitat preromàntica que irromp en el panorama creatiu de l'Europa del moment, més enllà de les propostes estrictament formals i de contingut del neoclassicisme, i també quant als motius i la intencionalitat dels dos autors.
