Diabetes care in Switzerland: good, but perfectible: a population-based cross-sectional survey.

BACKGROUND: While Switzerland invests a lot of money in its healthcare system, little is known about the quality of care delivered. The objective of this study was to assess the quality of care provided to patients with diabetes in the Canton of Vaud, Switzerland. METHODS: Cross-sectional study of 406 non-institutionalized adults with type 1 or 2 diabetes. Patients' characteristics, diabetes and process of care indicators were collected using a self-administered questionnaire. Process indicators (past 12 months) included HbA1C check among HbA1C-aware patients, eye assessment by ophtalmologist, microalbuminuria check, feet examination, lipid test, blood pressure and weight measurement, influenza immunization, physical activity recommendations, and dietary recommendations. Item-by-item (each process of care indicator: percentage of patients having received it), composite (mean percentage of recommended care: sum of received processes of care / sum of possible recommended care), and all-or-none (percentage of patients receiving all specified recommended care) measures were computed. RESULTS: Mean age was 64.4 years; 59% were men. Type 1 and type 2 diabetes were reported by 18.2% and 68.5% of patients, respectively, but diabetes type remained undetermined for almost 20% of patients. Patients were treated with oral anti-diabetic drugs (50%), insulin (23%) or both (27%). Of 219 HbA1C-aware patients, 98% reported ≥ one HbA1C check during the last year. Also, ≥94% reported ≥ one blood pressure measurement, ≥ one weight measurement or lipid test, and 68%, 64% and 56% had feet examination, microalbuminuria check and eye assessment, respectively. Influenza immunization was reported by 62% of the patients.The percentage of patients receiving all processes of care ranged between 14.2%-16.9%, and 46.6%-50.7%, when considering ten and four indicators, respectively. Ambulatory care utilization showed little use of multidisciplinary care, and low levels of participation in diabetes-education classes. CONCLUSIONS: While routine processes-of-care were performed annually in most patients, diabetes-specific risk screenings, influenza immunization, physical activity and dietary recommendations were less often reported; this was also the case for multidisciplinary care and participation in education classes. There is room for diabetes care improvement in Switzerland. These results should help define priorities and further develop country-specific chronic disease management initiatives for diabetes.

A cell-based model of extracellular-matrix-guided endothelial cell migration during angiogenesis.

Angiogenesis, the formation of new blood vessels sprouting from existing ones, occurs in several situations like wound healing, tissue remodeling, and near growing tumors. Under hypoxic conditions, tumor cells secrete growth factors, including VEGF. VEGF activates endothelial cells (ECs) in nearby vessels, leading to the migration of ECs out of the vessel and the formation of growing sprouts. A key process in angiogenesis is cellular self-organization, and previous modeling studies have identified mechanisms for producing networks and sprouts. Most theoretical studies of cellular self-organization during angiogenesis have ignored the interactions of ECs with the extra-cellular matrix (ECM), the jelly or hard materials that cells live in. Apart from providing structural support to cells, the ECM may play a key role in the coordination of cellular motility during angiogenesis. For example, by modifying the ECM, ECs can affect the motility of other ECs, long after they have left. Here, we present an explorative study of the cellular self-organization resulting from such ECM-coordinated cell migration. We show that a set of biologically-motivated, cell behavioral rules, including chemotaxis, haptotaxis, haptokinesis, and ECM-guided proliferation suffice for forming sprouts and branching vascular trees.

Involvement of PPARβ/δ in mesenchymal-epidermal interactions during skin wound healing

SUMMARY : Skin wound repair is a complex and highly coordinated process, where a variety of cell types unite to regenerate the damaged tissue. Several works have elucidated cellular and molecular mechanisms, in which mesenchymal-epidermal interactions play an essential role for the regulation of skin homeostasis and repair. Peroxisome Proliferator-Activated Receptors (PPARs) are ligand-activated transcription factors that belong to the nuclear receptor superfamily. Three related isotypes (PPARα, PPARß/δ and PPARγ) have been found, which exhibit distinct tissue distribution and specific physiological functions. PPARß/δ was identified as a crucial player of skin homeostasis. In the mouse skin, PPARß/δ has been described to control proliferation-differentiation state, adhesion and migration, and survival of the keratinocytes during healing. PPARß/δ has been implicated as well in the development of the hair follicles, in which mesenchymal-secreted hepatocyte growth factor (HGF) is involved. These data suggest that the biological activity of PPARß/δ is modulated by mesenchymal-epidermal interactions and that, in turn, PPARß/δ also modulates some of these signals. The aim of the present work was to elucidate the nature of the signals exchanged between the epidermis and dermis compartments, and more particularly those which are under the control of PPARß/δ. In the first part of the study, we showed that PPARß/8 in dermal fibroblasts down-regulates the mitotic activity of keratinocytes by inhibiting the IL-1 signalling pathway via the production of secreted IL-1 receptor antagonist (sIL-1Ra), a natural antagonist of this signalling. The regulation of IL-1 signalling by PPARß/δ is required for anon-pathological skin wound repair. These findings provide evidence for a novel homeostatic control of keratinocyte proliferation and differentiation mediated by the regulation of IL-1 signalling via dermal PPARß/δ fibroblasts. Proteolysis of the extracellular matrix (ECM) is a key process involved in wound repair and modifications in its activity are often associated with an alteration óf the wound closure. This process implies specific proteinases, as matrix metalloproteinases (MMPs), which are finely modulated by IL-1 signalling. In line with the first results, the second part of the work showed that MMP8 and MMP13, which are two important collagenases involved in mouse skin wound repair, are regulated by PPARß/δ. Their expression is indirectly down-regulated by dermal PPARß/δ, via the production of sIL-1Ra, resulting in the inhibition of IL-1 signalling, known to regulate the expression of numerous MMPs. We suggest that, in absence of PPARß/δ, the positive regulation of these two collagenases could participate to the delay of skin wound healing, which has been observed in mice deleted for PPARßlS. The potential therapeutic role of PPARß/b could be as well extending to inflammatory and hyperproliferative skin diseases involving IL-1 signalling, such as psoriasis or skin cancers. Quite interestingly, MMP1 (analogue of mouse MMP13) plays an essential role in human photoaging, suggesting that PPARß/δ could as well be an attractive target for photoprotection. RESUME : La cicatrisation est un processus complexe et extrêmement organisé, impliquant un grand nombre de cellules qui s'unissent pour régénérer le tissu endommagé. De nombreux travaux nous ont éclairés sur les mécanismes cellulaires et moléculaires, dans lesquels les interactions épidermo-mésenchymateuses détiennent un rôle capital à la fois dans la régulation de l'homéostasie et dans la réparation de la peau. PPAR (Peroxisome proliferatar-activated receptor), qui appartient à la superfamille des récepteurs nucléaires, se définit comme un facteur de transcription activé par des ligands très spécifiques. Trois isotypes (PPARa, PPARß/δ et PPARy) ont été décrits et sont caractérisés par une distribution tissulaire et des fonctions physiologiques clairement définies. PPARß/δ a été identifié comme étant un important acteur dans l'homéostasie de la peau. Chez la souris, il a été décrit comme contrôlant l'état de prolifération et de différenciation, le processus d'adhésion et de migration, ainsi que la survie des kératinocytes au cours de la cicatrisation. PPARßIS a également été défini comme contrôlant le développement des follicules pileux, impliquant la sécrétion par le mésenchyme du facteur de croissance HGF. Ces données suggèrent que l'activité biologique de PPARß/δ est modulée par des interactions épidermo-mésenchymateuses, et qu'en retour, il possède la capacité de moduler certains de ces signaux. L`objectif de ce travail a été d'élucider la nature des signaux échangés entre les compartiments épidermique et dermique, et plus particulièrement ceux qui sont sous le contrôle de PPARß/δ. Dans la première partie de l'étude, nous avons montré que les fibroblastes exprimant PPARß/δ réduisent l'activité mitotique des kératinocytes en inhibant la voie de signalisation IL-1, via la production de sIL-1Ra (secreted IL-1 receptor antagonist), défini comme un antagoniste naturel de cette voie de signalisation. La régulation de cette dernière par PPARß/δ est donc nécessaire pour une cicatrisation de type non pathologique. Ces résultats offrent donc une nouvelle preuve du contrôle de l'homéostasie et de l'état de prolifération/différenciation des kératinocytes par les fibroblastes exprimant PPARß/δ, en régulant la voie de signalisation IL-1. Le mécanisme de dégradation de la matrice extracellulaire (MEC) est une étape essentielle lors du processus de cicatrisation. Ainsi des modifications de cette activité protéolytïque sont souvent associées à une altération de la fermeture de la plaie. Ce processus implique des protéinases, comme les MMPs, qui sont finement modulés par la voie de signalisation IL-1. En accord avec les premiers résultats, la seconde partie des nos travaux a montré que les collagénases MMP8 et MMP13, connues pour être d'importantes molécules impliquées lors de la réparation tissulaire chez la souris, sont modulées par l'activité de PPARß/δ. Leurs expressions sont indirectement régulées par PPARß/δ, via la production. de sIL-1 Ra, entraînant ainsi l'inhibition de la voie de signalisation IL-1, décrite pour réguler l'expression de nombreuses MMPs, Nous suggérons donc qu'en absence de PPARß/δ, la régulation de ces deux collagénases pourrait être impliquée dans le retard de cicatrisation, observé chez les souris déficientes pour PPARß/δ. L'activité biologique de PPARß/δ pourrait être ainsi étendue à des maladies hyperproliferatives et inflammatoires de la peau, impliquant la voie de signalisation IL-1, comme le psoriasis ou certains cancers de la peau, et ce à des fins thérapeutiques. Il est aussi intéressant de relever que chez l'homme, MMP1 (présenté comme l'analogue de MMP13 de la souris} joue un rôle primordial dans le photo-vieillissement, nous suggérons donc que PPARß/δ pourrait ainsi être une cible attrayante concernant la photoprotection.

Turnaround across diverse global supply chains using shared metrics and change methodology: The Case of Amer Sports Corporation

Purpose - The purpose of this paper is to document the outcome of a global three-year long supply chain improvement initiative at a multi-national producer of branded sporting goods that is transforming from a holding structure to an integrated company. The case company is comprised of seven internationally well-known sport brands, which form a diverse set of independent sub-cases, on which the same supply chain metrics and change project approach was applied to improve supply chain performance. Design/methodology/approach - By using in-depth case study and statistical analysis the paper analyzes across the brands how supply chain complexity (SKU count), supply chain type (make or buy) and seasonality affect completeness and punctuality of deliveries, and inventory as the change project progresses. Findings - Results show that reduction in supply chain complexity improves delivery performance, but has no impact on inventory. Supply chain type has no impact on service level, but brands with in-house production are better in improving inventory than those with outsourced production. Non-seasonal business units improve service faster than seasonal ones, yet there is no impact on inventory. Research limitations/implications - The longitudinal data used for the analysis is biased with the general business trend, yet the rich data from different cases and three-years of data collection enables generalizations to a certain level. Practical implications - The in-depth case study serves as an example for other companies on how to initiate a supply chain improvement project across business units with tangible results. Originality/value - The seven sub-cases with their different characteristics on which the same improvement initiative was applied sets a unique ground for longitudinal analysis to study supply chain complexity, type and seasonality.

Food poverty in rural Northern Ireland

“Decent Food for All” (DFfA) was a three-year integrated, partnership-based programme committed to reducing food poverty and addressing inequalities in physical and financial access to safe healthy food in the Armagh and Dungannon area of Northern Ireland. DFfA is led by the Armagh and Dungannon Health Action Zone (ADHAZ) and involves the delivery of a range of programmes and workshops which provide practical community based focused help and advice on food issues and nutrition. A comprehensive research and evaluation programme entitled ‘All-island learning from the Decent Food for All programme’ runs throughout the lifetime of the programme, which ensures effective evaluation, and the sharing of best practices and experiences. The research and evaluation program is coordinated by the Institute of Public Health in Ireland (IPH) with cooperation from ADHAZ. Funding for the research is provided by the Food Safety Promotion Board. To take into account background changes not directly attributable to the DFfA Programme a matched comparison area was selected in the Newry/Mourne area of Co. Down. An accurate measure of the changes that have occurred over the period of the DFfA programme is required. Valid estimates of change are based on measures before and after the programme. Pre-test and post-test community surveys provide a wide range of measures. This fact-book highlights the findings from the pre-test community survey.The aims of the pre-test survey were to:- Provide pre-test measures of the Key Performance Indicators underpinning the Key Expected Outcomes of the DFfA programme;- Identify factors influencing these pre-test measures; and- Contribute to the development of the programmes in DFfA.

Response to the discussion paper on proposed Health Information Bill

The Institute of Public Health in Ireland is an all-island body which aims to improve health in Ireland by working to combat health inequalities and influence public policies in favour of health. The Institute promotes North-South co-operation in research, training, information and policy. The Institute commends the Department of Health and Children for producing the Discussion Paper on Proposed Health Information Bill (June 2008) and welcomes the opportunity to comment on it. The first objective of the Health Information: A National Strategy (2004) is to support the implementation of Quality and Fairness: A Health System for You (2001).The National Health Goals - such as ‘Better health for everyone’, ‘Fair access’ and ‘Responsive and appropriate care delivery’ - are expressed in terms of the health of the public as well as patients. The Discussion Paper focuses on personal information, and the data flows within the health system, that are needed to enhance medical care and maximise patient safety. The Institute believes that the Health Information Bill should also aim to more fully support the achievement of the National Health Goals and the public health function. This requires the development of more integrated information systems that link the healthcare sector and other sectors. Assessment of health services performance - in terms of the public’s health, health inequalities and achievement of the National Health Goals - require such information systems. They will enable the construction of public health key performance indicators for the healthcare services.

Eusociality and cooperation

The evolution of eusociality, here defined as the emergence of societies with reproductive division of labour and cooperative brood care, was first seen as a challenge to Darwin's theory of evolution by natural selection. Why should individuals permanently forgo direct reproduction to help other individuals to reproduce? Kin selection, the indirect transmission of genes through relatives, is the key process explaining the evolution of permanently nonreproductive helpers. However, in some taxa helpers delay reproduction until a breeding opportunity becomes available. Overall, eusociality evolved when ecological conditions promote stable associations of related individuals that benefit from jointly exploiting and defending common resources. High levels of cooperation and robust mechanisms of division of labour are found in many animal societies. However, conflicts among individuals are still frequent when group members that are not genetically identical compete over reproduction or resource allocation.

How to manage a virtual library?

Introduction. The Andalusian Public Health System Virtual Library (Biblioteca Virtual del Sistema Sanitario Público de Andalucía, BV-SSPA) was created in June 2006, after being determined by the II Quality Plan in the key process Guarantee the Knowledge Exchange into the Health System which was established by the Strategy IV, Knowledge Management, 2005-2008. It is a government strategy with its own budget and management with the aim of rationalizing the subscriptions into the Andalusian Health System and democratizing the health professional access to qualify scientific information, regardless of the professional workplace. Andalusia is a wide region with more than 8 million inhabitants, more than 90,000 health professionals for 41 hospitals, 1,500 primary healthcare centres, and 12 centres for non-medical attention purposes, and the Virtual Library was created to cover all this Health Services. Before the creation of the BV-SSPA every centre had its own budget and management decisions concerning scientific resources, with the creation of the BV-SSPA both management and budget were centralized. Objectives. With this work we pretend to analyze if the results after these five years have reached the expectations from an economic point of view and determine if really we can offer a benefit to the Andalusian Professional and Society in general. We will demonstrate the following: - The BV-SSPA supposed a cost reduction. It meant cost-effectiveness. - It resulted in Economics of Scale, as we have every year more resources and services investing a minor proportional amount of money. - In terms of Efficiency it implemented more services than the System had before its creation, we a lower budget. Methods. The BV-SSPA was appointed the only intermediary for contracting electronic resources destined to the Andalusian Health System. This had some consequences which should be analyzed: - Hospitals were not allowed to subscribe any resources. - Services offered for the whole System. - A remote access system was created. - Tools to give more visibility to the Public Health System were developed. - Negotiations techniques changed as the BV-SSPA is stronger than individual hospitals. Results. - The amount of 2,431 electronic reviews, 8 data bases and other scientific information resources at the disposal of the Andalusian Health System Professionals and available worldwide requiring only an internet connection. Before the BV-SSPA, 5,267 titles were subscribed by hospital and 2,967 of them were subscribed repeatedly (by two or more hospitals), this represented more than 55%. The rationalization of the subscription investment has been reached. - The establishment of several important scientific services for the whole territory of Andalusia, not only big hospitals. - The use of appropriate tools through a Web 2.0 and Social Media to be acknowledged by most National Health Professionals. Conclusions. It has been demonstrated that the BV-SSPA has become the Central Unit for purchasing, offering librarian services and a reference for users in terms of knowledge management, but from the point of view of business it has also obtained the following results: - Cost-Effectiveness: Its budget for subscriptions is lower than the hospital former one in a 30% and now more electronic resources are available. - Economics of Scale: Near 95,000 health professionals can access this Virtual Library in 2010. Before its creation Professionals for small hospital and Primary Care centres were not able to access to scientific information subscribed by big hospitals. - Efficiency Besides the central electronic purchasing, services were created for the System, without increasing the expenses: - Remote access to all the library resources independent of the user’s location. The BV-SSPA usage increased in a 147% in 2008, when it was installed. - The Document Supply Service implemented in 2009. - The Institutional Repository which contains the whole intellectual, scientific production generated by the Andalusian Public Health Professionals as a result of their healthcare, research or managing activity. - The creation of an application developed by the BV-SSPA to study the Andalusian Health System Scientific Production. - The visibility of the Andalusian Health System reached thanks to the BV-SSPA, through the numerous events in which it participates and organizes such as the 2nd. European National Digital Libraries of Health Conferences and the National Conference of Health Science Information and Documentation held in Cadiz in 2010; and its profile in social media where it can be contacted by citizens and health professionals all over the world. - Negotiation with electronic resource suppliers is much more advantageous as the BV-SSPA is stronger to deal with them thanks to its consolidated budget, its managing independence and its visibility.
