Anti-embryonation immunity in murine schistosomiasis japonica (Philippines)

The hypothesis that granuloma modulation and disease abatement in chronic infection with Schistosoma japonicum could be ascribed to antibody-mediated effects on egg maturation and egg viability, arose from studies performed with mice in the Philippines. This novel hypothesis has not yet been integrated into the schistosomiasis literature despite being formulated more than a decade ago. One reason for this is that the phenomenon might be confined to S. japonicum, even S. japonicum (Philippines).

Long-term use and tolerability of irbesartan for control of hypertension.

In this review, we discuss the pharmacological and clinical properties of irbesartan, a noncompetitive angiotensin II receptor type 1 antagonist, successfully used for more than a decade in the treatment of essential hypertension. Irbesartan exerts its antihypertensive effect through an inhibitory effect on the pressure response to angiotensin II. Irbesartan 150-300 mg once daily confers a lasting effect over 24 hours, and its antihypertensive efficacy is further enhanced by the coadministration of hydrochlorothiazide. Additionally and partially beyond its blood pressure-lowering effect, irbesartan reduces left ventricular hypertrophy, favors right atrial remodeling in atrial fibrillation, and increases the likelihood of maintenance of sinus rhythm after cardioversion in atrial fibrillation. In addition, the renoprotective effects of irbesartan are well documented in the early and later stages of renal disease in type 2 diabetics. Furthermore, both the therapeutic effectiveness and the placebo-like side effect profile contribute to a high adherence rate to the drug. Currently, irbesartan in monotherapy or combination therapy with hydrochlorothiazide represent a rationale pharmacologic approach for arterial hypertension and early-stage and late-stage diabetic nephropathy in hypertensive type II diabetics.

Age-period-cohort analysis of oral cancer mortality in Europe: the end of an epidemic?

Over the last decade, mortality from oral and pharyngeal cancer has been declining in most European countries, but it had been increasing substantially in Hungary, Slovakia and a few other countries of central Europe, reaching rates comparable to those of lung cancer in several western European countries in males. To update trends in oral cancer mortality and further analyse the recent epidemic in central Europe, official death certifications for oral and pharyngeal cancer for 37 European countries were derived over the period 1970-2007, and an age-period-cohort model was fitted for selected countries. Male oral cancer mortality continued to decline in most European countries, including the Russian Federation, and, more importantly, it also started to decline in some of the countries with the highest male rates, i.e. Hungary and Slovakia; persisting rises were, however, observed in Belarus, Bulgaria and Romania. Oral cancer mortality rates for women were lower than in men and showed no appreciable trend over recent periods in the EU overall. Estimates from the age-period-cohort analysis for most selected countries showed a fall in effects for the cohorts born after the 1950s. For the period effect displayed a rise for the earlier periods, an inversion in the 1990s and a continuous fall up to the last studied period. Only some former non-market economy countries, like Romania, Ukraine and Lithuania, had rising cohort effect trends up to most recent generations. The major finding of this updated analysis of oral cancer mortality is the leveling of the epidemic for men in most European countries, including Hungary and other central European countries, where mortality from this cancer was exceedingly high. These trends essentially reflect the changes in alcohol and tobacco consumption in various populations.

Assessing ageing of individual T lymphocytes: mission impossible?

Effector T lymphocytes are the progeny of a limited number of antigen-specific precursor cells and it has been estimated that clonotypic human T cells may expand million fold on their way reaching high cell numbers that are sufficient for immune protection. Moreover, memory T cell responses are characterized by repetitive expansion of antigen-specific T cell clonotypes, and limitations in the proliferative capacity could lead to immune senescence. Because telomeres progressively shorten as a function of cell division, telomere length is a powerful indicator of the replicative in vivo history of human T lymphocytes. In this review, we summarize observations made over the last decade on telomere length dynamics of well-defined T cell populations derived from healthy donors and patients with infectious disease or cancer. We focus on T cell differentiation, T cell ageing, and natural and vaccine induced immune responses. We also discuss the scientific evidence for in vivo replicative senescence of antigen-specific T cells, and evaluate the available methods for measuring telomere lengths and telomerase activity, and their potential and limitations to increase our understanding of T cell physiology.

High altitude, a natural research laboratory for the study of cardiovascular physiology and pathophysiology.

High altitude constitutes an exciting natural laboratory for medical research. Although initially, the aim of high-altitude research was to understand the adaption of the organism to hypoxia and find treatments for altitude-related diseases, during the past decade or so, the scope of this research has broadened considerably. Two important observations led the foundation for the broadening of the scientific scope of high-altitude research. First, high-altitude pulmonary edema represents a unique model that allows studying fundamental mechanisms of pulmonary hypertension and lung edema in humans. Second, the ambient hypoxia associated with high-altitude exposure facilitates the detection of pulmonary and systemic vascular dysfunction at an early stage. Here, we will review studies that, by capitalizing on these observations, have led to the description of novel mechanisms underpinning lung edema and pulmonary hypertension and to the first direct demonstration of fetal programming of vascular dysfunction in humans.

Diseño de filtros Bulk Acoustic Wave con topología en escalera de altas prestaciones

Degut als avenços als dispositius de telecomunicacions durant l’última dècada, els filtres integrats en aquests dispositius requereixen de millors prestacions, baix cost i, per sobre de tot, requereixen unes dimensions el més reduïdes possibles. Tot i que avui dia encara s’utilitzen el filtres SAW en aquests dispositius, cada cop més s’estan substituint pels filtres amb tecnologia BAW, ja que tenen millors prestacions. En l’actualitat la topologia BAW més extensa i utilitzada és la topologia en escala. En aquest projecte s’ha portat a terme un estudi en profunditat de les limitacions dels filtres en escala. A partir de les limitacions detectades s’ha presentat una nova estructura de disseny per aquest tipus de filtres que redueix les dimensions d’aquests i millora considerablement algunes de les limitacions de l’estructura convencional. Paral·lelament s’ha desenvolupat una metodologia sistemàtica pròpia pel disseny de la nova estructura.

Analyse des cannabinoïdes par spectrométrie de masse en mode tandem = Analysis of cannabinoids by tandem mass spectrometry

Depuis quelques années, la spectrométrie de masse en tandem (MS/MS) ne cesse de gagner du terrain comme méthode d'analyse en toxicologie forensique, notamment pour le dosage des cannabinoïdes. Couplée à la chromatographie liquide (LC) ou gazeuse (GC), elle permet l'identification fiable et le dosage rapide du THC, de son précurseur acide, et de ses principaux métabolites, y compris les glucuronides. Au cours de ces dix dernières années, un nombre significatif de publications sont parues sur ce sujet. L'objectif de cet article est de passer en revue les analyses par spectrométrie de masse en tandem des cannabinoïdes dans diverses matrices biologiques. In recent years, tandem mass spectrometry (MS/MS) is gaining ground as a reference method of analysis in clinical and forensic toxicology, especially for the determination of cannabinoids. Coupled to liquid chromatography (LC) or gas chromatography (GC), it allows the definitive identification and rapid determination of THC, its acid precursor, and its major metabolites, including the glucuronides. During the past decade, several methods of analysis of cannabinoids in different matrices have appeared on this subject. The aim of this paper is to review the analysis of cannabinoids by tandem mass spectrometry methods in various biological matrices

Defining secretion processes in astrocytes

During the last decade, evidence that release of chemical transmitters from astrocytes might modulate neuronal activity (the so-called "gliotransmission") occurs in situ has been extensively provided. Nevertheless, gliotransmission remains a highly debated topic because of the lack of direct morphological and functional evidence. Here we provided new information supporting gliotransmission, by i) deepen knowledge about specific properties of regulated secretion of glutamatergic SLMVs, and ii) investigating the involvement of astrocytes in the transmission of dopamine, a molecule whose interaction with astrocytes is likely to occur, but it's still not proven.¦VGLUT-expressing glutamatergic SLMVs have been previously identified both in situ and in vitro, but description of kinetics of release were still lacking. To elucidate this issue, we took advantage of fluorescent tools (styryl dyes and pHluorin) and adapted experimental paradigms and analysis methods previously developed to study exo-endocytosis and recycling of glutamatergic vesicles at synapses. Parallel use of EPIfluorescence and total internal reflection (TIRF) imaging allowed us to find that exo-endocytosis processes in astrocytes are extremely fast, with kinetics in the order of milliseconds, able to sustain and follow neuronal signalling at synapses. Also, exocytosis of SLMVs is under the control of fast, localized Ca2+ elevations in close proximity of SLMVs and endoplasmatic reticulum (ER) tubules, the intracellular calcium stores. Such complex organization supports the fast stimulus-secretion coupling we described; localized calcium elevations have been recently observed in astrocytes in situ, suggesting that these functional microdomains might be present in the intact tissue. In the second part of the work, we investigated whether astrocytes possess some of the benchmarks of brain dopaminergic cells. It's been known for years that astrocytes are able to metabolize monoamines by the enzymes MAO and COMT, but to date no clear information that glial cells are able to uptake and store monoamines have been provided. Here, we identified a whole apparatus for the storage, degradation and release of monoamines, at the ultrastructural level. Electron microscopy immunohistochemistry allowed us to visualize VMAT2- and dopamine-positive intracellular compartments within astrocytic processes, i.e. dense -core granules and cisterns. These organelles might be responsible for dopamine release and storage, respectively; interestingly, this intracellular distribution is reminiscent of VMAT2 expression in dendrites if neurons, where dopamine release is tonic and plays a role in the regulation of its a basal levels, suggesting that astrocytic VMAT2 is involved in the homeostasis of dopamine in healthy brains of adult mammals.¦Durant cette dernière décennie, de nombreux résultats sur le relâchement des transmetteurs par les astrocytes pouvant modulé l'activité synaptique (gliotransmission) ont été fournis. Néanmoins, la gliotransmission reste un processus encore très débattu, notamment à cause de l'absence de preuves directes, morphologique et fonctionnelle démontrant ce phénomène. Nous présentons dans nos travaux de nombreux résultats confortant l'hypothèse de la gliotransmission, dont i) une étude approfondie sur les propriétés spatiales et temporelles de la sécrétion régulée du glutamate dans les astrocytes, et ii) une étude sur la participation des astrocytes dans la transmission de la dopamine, une neuromodulateur dont l'interaction avec les astrocytes est fortement probable, mais qui n'a encore jamais été prouvée. L'expression des petites vésicules (SLMVs - Synaptic Like Micro Vesicles) glutamatergiques exprimant les transporteurs vésiculaires du glutamate (VGLUTs) dans les astrocytes a déjà été prouvé tant in situ qu'in vitro. Afin de mettre en évidence les propriétés précises de la sécrétion de ces organelles, nous avons adapté à nos études des méthodes expérimentales conçues pour observer les processus de exocytose et endocytose dans les neurones. Les résolutions spatiale et temporelle obtenues, grâce a l'utilisation en parallèle de l'épi fluorescence et de la fluorescence a onde évanescente (TIRF), nous ont permis de montrer que la sécrétion régulée dans les astrocytes est un processus extrêmement rapide (de l'ordre de la milliseconde) et qu'elle est capable de soutenir et de suivre la transmission de signaux entre neurones. Nous avons également découvert que cette sécrétion a lieu dans des compartiments subcellulaires particuliers où nous observons la présence du reticulum endoplasmique (ER) ainsi que des augmentations rapides de calcium. Cette organisation spatiale complexe pourrait être la base morphologique du couplage rapide entre le stimulus et la sécrétion. Par ailleurs, plusieurs études récentes in vivo semblent confirmer l'existence de ces compartiments. Depuis des années nous savons que les astrocytes sont capables de métaboliser les monoamines par les enzymes MAO et COMT. Nous avons donc fourni de nouvelles preuves concernant la présence d'un appareil de stockage dans les astrocytes participant à la dégradation et la libération de monoamines au niveau ultrastructurelle. Grâce à la microscopie électronique, nous avons découvert la présence de compartiments intracellulaires exprimant VMAT2 dans les processus astrocytaires, sous forme de granules et des citernes. Ces organelles pourraient donc être responsables à la fois du relâchement et du stockage de la dopamine. De manière surprenante, cette distribution intracellulaire est similaire aux dendrites des neurones exprimant VMAT2, où la dopamine est libérée de façon tonique permettant d'agir sur la régulation de ses niveaux de base. Ces résultats, suggèrent une certaine participation des VMAT2 présents dans les astrocytes dans le processus d'homéostase de la dopamine dans le cerveau.¦A de nombreuses reprises, dans des émissions scientifiques ou dans des films, il est avancé que les hommes n'utilisent que 10% du potentiel de leur cerveau. Cette légende provient probablement du fait que les premiers chercheurs ayant décrit les cellules du cerveau entre le XIXème et le XXeme siècle, ont montré que les neurones, les cellules les plus connues et étudiées de cet organe, ne représentent seulement que 10% de la totalité des cellules composant du cerveau. Parmi les 90% restantes, les astrocytes sont sans doute les plus nombreuses. Jusqu'au début des années 90, les astrocytes ont été plutôt considérés peu plus que du tissu conjonctif, ayant comme rôles principaux de maintenir certaines propriétés physiques du cerveau et de fournir un support métabolique (énergie, environnement propre) aux neurones. Grace à la découverte que les astrocytes ont la capacité de relâcher des substances neuro-actives, notamment le glutamate, le rôle des astrocytes dans le fonctionnement cérébral a été récemment reconsidérée.¦Le rôle du glutamate provenant des astrocytes et son impact sur la fonctionnalité des neurones n'a pas encore été totalement élucidé, malgré les nombreuses publications démontrant l'importance de ce phénomène en relation avec différentes fonctions cérébrales. Afin de mieux comprendre comment les astrocytes sont impliqués dans la transmission cérébrale, nous avons étudié les propriétés spatio-temporelles de cette libération grâce à l'utilisation des plusieurs marqueurs fluorescents combinée avec différentes techniques d'imagerie cellulaires. Nous avons découvert que la libération du glutamate par les astrocytes (un processus maintenant appelé "gliotransmission") était très rapide et contrôlée par des augmentations locales de calcium. Nous avons relié ces phénomènes à des domaines fonctionnels subcellulaires morphologiquement adaptés pour ce type de transmission. Plus récemment, nous avons concentré nos études sur un autre transmetteur très important dans le fonctionnement du cerveau : la dopamine. Nos résultats morphologiques semblent indiquer que les astrocytes ont la capacité d'interagir avec ce transmetteur, mais d'une manière différente comparée au glutamate, notamment en terme de rapidité de transmission. Ces résultats suggèrent que le astrocytes ont la capacité de modifier leurs caractéristiques et de s'adapter à leur environnement par rapport aux types de transmetteur avec lequel ils doivent interagir.

'Hearts and bones': the ups and downs of 'plasticity' in stem cell biology.

More than a decade ago, 'plasticity' suddenly became a 'fashionable' topic with overemphasized implications for regenerative medicine. The concept of 'plasticity' is supported by old transplantation work, at least for embryonic cells, and metaplasia is a classic example of plasticity observed in patients. Nevertheless, the publication of a series of papers showing rare conversion of a given cell type into another unrelated cell raised the possibility of using any unaffected tissue to create at will new cells to replace a different failing tissue or organ. This resulted in disingenuous interpretations and a reason not to fund anymore research on embryonic stem cells (ESc). Moreover, many papers on plasticity were difficult to reproduce and thus questioned; raising issues about plasticity as a technical artefact or a consequence of rare spontaneous cells fusion. More recently, reprogramming adult differentiated cells to a pluripotent state (iPS) became possible, and later, one type of differentiated cell could be directly reprogrammed into another (e.g. fibroblasts into neurons) without reverting to pluripotency. Although the latter results from different and more robust experimental protocols, these phenomena also exemplify 'plasticity'. In this review, we want to place 'plasticity' in a historical perspective still taking into account ethical and political implications.

The Last Fifteen Years of Schistosomiasis in Venezuela: Features and Evolution

Control of schistosomiasis in Venezuela has been a topic of major interest and controversy among the metaxenic parasitosis. A small area of transmission of approximately 15,000 km2 was thought to be eradicated some years ago. However, some epidemiological characteristics of our transmission area have limited the success on the way toward eradication. Since 1945, when the Schistosomiasis Control Program started, the prevalence in the endemic area has decreased from 14% in 1943 to 1.4% in 1996. Until 1982, the surveillance of active cases was based on massive stool examination. Since then, the Schistosomiasis Research Group (SRG) recommended the additional use of serologic tests in the Control Program and the selective or massive chemotherapy depending on serological and parasitological prevalence of each community. At present, the real prevalence is underestimated due to the fact that approximately 80% of the individuals eliminate less than 100 eggs/g of feces. Those persons could be responsible for the maintenance of the foci going on and therefore limiting the impact of the control measures. Efforts of the SRG are being oriented toward improvement of immunodiagnostic tests by using defined antigens (enzymes) and chemically synthesized peptides, derived from relevant molecules of the parasite, either for antibodies or antigens search. On the other hand, introduction of snail competitors has been a biological weapon in the control of the intermediate host in certain areas. However, the recent reinfestation of water courses by Biomphalaria glabrata, the increased prevalence in some areas, together with important administrative changes at the Control Program of the Minister of Health, have arisen new questions and doubts, challenging the eradication strategy proposed during the last decade.

Comrades or Culprits? Donor Engagement and Budget Transparency in Aid Dependent Countries

Budget transparency has come to be considered a key aspect of governance. Over the past decade, donors have invested increasing resources in strengthening processes through which budget transparency in developing countries can be enhanced. According to the 2008 Open Budget Index (OBI) Report, however, aid dependency and budget transparency appear to be inversely correlated. This article looks at the role of donor agencies in promoting or preventing budget transparency in aid dependent countries. It analyzes data for a sample of 16 aid-dependent countries included in the OBI, to test some preliminary hypotheses and select six countries for which more detailed findings are then presented. All of these countries have implemented reforms aimed at enhancing budget transparency, with substantial donor support. These, however, often had only limited success, partly because they were not well adapted to the local context, and partly because donors put limited emphasis on improving public access to budget information. Donor efforts were also often offset by other characteristics of donor interventions, namely their fragmentation, lack of transparency, and limited use of program aid modalities such as budget support and pooled sector funding.

Oncology clinicians' defenses and adherence to communication skills training with simulated patients: an exploratory study.

The aim of this exploratory study was to assess the impact of clinicians' defense mechanisms-defined as self-protective psychological mechanisms triggered by the affective load of the encounter with the patient-on adherence to a communication skills training (CST). The population consisted of oncology clinicians (N = 31) who participated in a CST. An interview with simulated cancer patients was recorded prior and 6 months after CST. Defenses were measured before and after CST and correlated with a prototype of an ideally conducted interview based on the criteria of CST-teachers. Clinicians who used more adaptive defense mechanisms showed better adherence to communication skills after CST than clinicians with less adaptive defenses (F(1, 29) = 5.26, p = 0.03, d = 0.42). Improvement in communication skills after CST seems to depend on the initial levels of defenses of the clinician prior to CST. Implications for practice and training are discussed. Communication has been recognized as a central element of cancer care [1]. Ineffective communication may contribute to patients' confusion, uncertainty, and increased difficulty in asking questions, expressing feelings, and understanding information [2, 3], and may also contribute to clinicians' lack of job satisfaction and emotional burnout [4]. Therefore, communication skills trainings (CST) for oncology clinicians have been widely developed over the last decade. These trainings should increase the skills of clinicians to respond to the patient's needs, and enhance an adequate encounter with the patient with efficient exchange of information [5]. While CSTs show a great diversity with regard to their pedagogic approaches [6, 7], the main elements of CST consist of (1) role play between participants, (2) analysis of videotaped interviews with simulated patients, and (3) interactive case discussion provided by participants. As recently stated in a consensus paper [8], CSTs need to be taught in small groups (up to 10-12 participants) and have a minimal duration of at least 3 days in order to be effective. Several systematic reviews evaluated the impact of CST on clinicians' communication skills [9-11]. Effectiveness of CST can be assessed by two main approaches: participant-based and patient-based outcomes. Measures can be self-reported, but, according to Gysels et al. [10], behavioral assessment of patient-physician interviews [12] is the most objective and reliable method for measuring change after training. Based on 22 studies on participants' outcomes, Merckaert et al. [9] reported an increase of communication skills and participants' satisfaction with training and changes in attitudes and beliefs. The evaluation of CST remains a challenging task and variables mediating skills improvement remain unidentified. We recently thus conducted a study evaluating the impact of CST on clinicians' defenses by comparing the evolution of defenses of clinicians participating in CST with defenses of a control group without training [13]. Defenses are unconscious psychological processes which protect from anxiety or distress. Therefore, they contribute to the individual's adaptation to stress [14]. Perry refers to the term "defensive functioning" to indicate the degree of adaptation linked to the use of a range of specific defenses by an individual, ranging from low defensive functioning when he or she tends to use generally less adaptive defenses (such as projection, denial, or acting out) to high defensive functioning when he or she tends to use generally more adaptive defenses (such as altruism, intellectualization, or introspection) [15, 16]. Although several authors have addressed the emotional difficulties of oncology clinicians when facing patients and their need to preserve themselves [7, 17, 18], no research has yet been conducted on the defenses of clinicians. For example, repeated use of less adaptive defenses, such as denial, may allow the clinician to avoid or reduce distress, but it also diminishes his ability to respond to the patient's emotions, to identify and to respond adequately to his needs, and to foster the therapeutic alliance. Results of the above-mentioned study [13] showed two groups of clinicians: one with a higher defensive functioning and one with a lower defensive functioning prior to CST. After the training, a difference in defensive functioning between clinicians who participated in CST and clinicians of the control group was only showed for clinicians with a higher defensive functioning. Some clinicians may therefore be more responsive to CST than others. To further address this issue, the present study aimed to evaluate the relationship between the level of adherence to an "ideally conducted interview", as defined by the teachers of the CST, and the level of the clinician' defensive functioning. We hypothesized that, after CST, clinicians with a higher defensive functioning show a greater adherence to the "ideally conducted interview" than clinicians with a lower defensive functioning.

Evolutionary ecology of learning: insights from fruit flies

Ecologically and evolutionarily oriented research on learning has traditionally been carried out on vertebrates and bees. While less sophisticated than those animals, fruit flies (Drosophila) are capable of several forms of learning, and have an advantage of a short generation time, which makes them an ideal system for experimental evolution studies. This review summarizes the insights into evolutionary questions about learning gained in the last decade from evolutionary experiments on Drosophila. These experiments demonstrate that Drosophila have the genetic potential to evolve substantially improved learning performance in ecologically relevant learning tasks. In at least one set of selected populations the improved learning generalized to another task than that used to impose selection, involving a different behavior, different stimuli, and a different sensory channel for the aversive reinforcement. This improvement in learning ability was associated with reduction in other fitness-related traits, such as larval competitive ability and lifespan, pointing out to evolutionary trade-offs of improved learning. These trade-offs were confirmed by other evolutionary experiments where reduction in learning performance was observed as a correlated response to selection for tolerance to larval nutritional stress or for delayed aging. Such trade-offs could be one reason why fruit flies have not fully used up their evolutionary potential for learning ability. Finally, another evolutionary experiment with Drosophila provided the first direct evidence for the long-standing ideas that learning can under some circumstances accelerate and in other slow down genetically-based evolutionary change. These results demonstrate the usefulness of fruit flies as a model system to address evolutionary questions about learning.

Evolution of the clinical and epidemiological knowledge about Chagas disease 90 years after its discovery

Three different periods may be considered in the evolution of knowledge about the clinical and epidemiological aspects of Chagas disease since its discovery: (a) early period concerning the studies carried out by Carlos Chagas in Lassance with the collaboration of other investigators of the Manguinhos School. At that time the disease was described and the parasite, transmitters and reservoirs were studied. The coexistence of endemic goiter in the same region generated some confusion about the clinical forms of the disease; (b) second period involving uncertainty and the description of isolated cases, which lasted until the 1940 decade. Many acute cases were described during this period and the disease was recognized in many Latin American countries. Particularly important were the studies of the Argentine Mission of Regional Pathology Studies, which culminated with the description of the Romaña sign in the 1930 decade, facilitating the diagnosis of the early phase of the disease. However, the chronic phase, which was the most important, continued to be difficult to recognize; (c) period of consolidation of knowledge and recognition of the importance of Chagas disease. Studies conducted by Laranja, Dias and Nóbrega in Bambuí updated the description of Chagas heart disease made by Carlos Chagas and Eurico Villela. From then on, the disease was more easily recognized, especially with the emphasis on the use of a serologic diagnosis; (d) period of enlargement of knowledges on the disease. The studies on denervation conducted in Ribeirão Preto by Fritz Köberle starting in the 1950 decade led to a better understanding of the relations between Chagas disease and megaesophagus and other visceral megas detected in endemic areas.

IPH response to DHSSPS and Food Standards Agency (NI) Front of Pack Labelling consultation

From 2016, it will be mandatory for most pre-packed food to carry nutrition labelling.  This provides an opportunity to review the provision of additional nutrition labelling that is provided voluntarily on the front of packs.  The Governments across the UK are committed to the provision of nutritional information to help consumers make better informed food choices. Key points from IPH response Obesity and related chronic conditions are already very prevalent and are expected to increase over the next decade, placing greater financial burden on health care services. Helping consumers to make informed choices about their diet is an important aspect of tackling obesity. Providing clear consistent and easy to understand front of pack (FoP) nutrition information is important in helping consumers to make healthy choices. IPH would support FoP nutrition information using the traffic light labelling scheme and High/Medium/Low text. FoP nutrition labelling should be supported by a public information campaign to educate consumers about portion sizes and recommended daily intakes of fat, sugar and salt. IPH would support a nutrition labelling approach which empowers and enables consumers to take responsibility for their own health through informed dietary choices. The FoP traffic light labelling scheme has the potential to encourage healthier product formulation as manufacturers pursue market share. This in turn would contribute to wider availability of healthier products.
