Association between education and quality of diabetes care in Switzerland

PURPOSE: Low socioeconomic status is associated with higher prevalence of diabetes, worse outcomes, and worse quality of care. We explored the relationship between education, as a measure of socioeconomic status, and quality of care in the Swiss context. PATIENTS AND METHODS: Data were drawn from a population-based survey of 519 adults with diabetes during fall 2011 and summer 2012 in a canton of Switzerland. We assessed patients and diabetes characteristics. Eleven indicators of quality of care were considered (six of process and five of outcomes of care). After bivariate analyses, regression analyses adjusted for age, sex, and diabetic complications were performed to assess the relationship between education and quality of care. RESULTS: Of 11 quality-of-care indicators, three were significantly associated with education: funduscopy (patients with tertiary versus primary education were more likely to get the exam: odds ratio, 1.8; 95% confidence interval [CI], 1.004-3.3) and two indicators of health-related quality of life (patients with tertiary versus primary education reported better health-related quality of life: Audit of Diabetes-Dependent Quality of Life: β=0.6 [95% CI, 0.2-0.97]; SF-12 mean physical component summary score: β=3.6 [95% CI, 0.9-6.4]). CONCLUSION: Our results suggest the presence of educational inequalities in quality of diabetes care. These findings may help health professionals focus on individuals with increased needs to decrease health inequalities.

Patterns of Subject Mix in Higher Education Institutions : A First Empirical Analysis Using the AQUAMETH Database

Teaching and research are organised differently between subject domains: attempts to construct typologies of higher education institutions, however, often do not include quantitative indicators concerning subject mix which would allow systematic comparisons of large numbers of higher education institutions among different countries, as the availability of data for such indicators is limited. In this paper, we present an exploratory approach for the construction of such indicators. The database constructed in the AQUAMETH project, which includes also data disaggregated at the disciplinary level, is explored with the aim of understanding patterns of subject mix. For six European countries, an exploratory and descriptive analysis of staff composition divided in four large domains (medical sciences, engineering and technology, natural sciences and social sciences and humanities) is performed, which leads to a classification distinguishing between specialist and generalist institutions. Among the latter, a further distinction is made based on the presence or absence of a medical department. Preliminary exploration of this classification and its comparison with other indicators show the influence of long term dynamics on the subject mix of individual higher education institutions, but also underline disciplinary differences, for example regarding student to staff ratios, as well as national patterns, for example regarding the number of PhD degrees per 100 undergraduate students. Despite its many limitations, this exploratory approach allows defining a classification of higher education institutions that accounts for a large share of differences between the analysed higher education institutions.

Contribution of physical education to overall physical activity.

For many children, physical activity (PA) during physical education (PE) lessons provides an important opportunity for being physically active. Although PA during PE has been shown to be low, little is known about the contribution of PA during PE to overall PA. The aim was therefore to assess children's PA during PE and to determine the contribution of PE to overall PA with special focus on overweight children. Accelerometer measurements were done in 676 children (9.3 ± 2.1 years) over 4-7 days in 59 randomly selected classes. Moderate-and-vigorous PA (MVPA; ≥ 2000 counts/min) during PE (MVPA(PE) ), overall MVPA per day (MVPA(DAY) ), and a comparison of days with and without PE were calculated by a regression model with gender, grade, and weight status (normal vs overweight) as fixed factors and class as a random factor. Children spent 32.8 ± 15.1% of PE time in MVPA. Weight status was not associated to MVPA(PE) . MVPA(PE) accounted for 16.8 ± 8.5% of MVPA(DAY) , and 17.5 ± 8.2% in overweight children. All children were more active on days with PE than on days without PE (differences: 16.1 ± 29.0 min of MVPA(DAY) ; P ≤ 0.001; 13.7 ± 28.0 min for overweight children). Although MVPA(PE) was low, PE played a considerable role in providing PA and was not compensated by reducing extracurricular MVPA.

Immunomodulation nutritionnelle chez les patients atteints de mucoviscidose

SUMMARY Pulmonary Pulmonary disease is the primary cause of morbidity and mortality in cystic fibrosis patients (CF). Airways of CF patients are early colonized by various bacteriae, and an intense inflammatory response participates to airways destruction. Accumulation of neutrophils releasing proteolytic enzymes and free radicals induce progressive lung tissue destruction in CF. Among several inflammatory mediators implicated in this process, chemotactic factors such as leukotriene B4 (LTB4), product of arachidonic omega-6 polyunsaturated fatty acid (PUFA), plays an important role. Many anti-inflammatory therapies including corticosteroids, ibuprofen, macrolides, antioxidants and antiproteinases have been proposed in CF over the last 20 years. In complement to these various approaches, dietary supplementation with polyunsaturated fatty acids (PUFA) omega-3, known to favor the synthesis of less inflammatory leukotriene B5 (LTB5), could also represent a potential. therapy. The objective of this thesis was to assess the impact of this nutritional approach on several CF neutrophil functions. In addition, we have also examined the influence of this approach on various clinical parameters, to assess the feasibility of future studies specifically oriented towards clinical effects. To that endeavour, a high performance liquid chromatography method has been developed and validated, allowing the simultaneous determination of LTB4 and LTB5 produced by stimulated human polymorphonuclear leukocytes. This method was applied for the analysis of samples collected from CF patients taking part to a double-blind, randomized, crossover placebo-controlled clinical trial aiming at evaluating in these patients the immunomodulatary effect of a liquid supplementation enriched in omega-3 PUFA in CF. This study has shown that omega-3 PUFA are incorporated in CF neutrophil membranes and results into a modulation of leucotrienes B production, as testified by a three fold decrease in LTB4/LTB5 ratio after omega-3 PUFA supplementation. However, no clinical improvement was observed upon omega-3 supplementation, very reproducible results observed allow to be optimistic for a future larger trial focused on clinical outcomes. In conclusion, even if the results show that omega-3 PUFA are absorbed by CF patients and that the subsequent decrease in LTB4/LTB5 ratio suggests that in such conditions, neutrophils may produce less pro-inflammatory mediators, the clinical relevance of those observations remains to be demonstrated. Future multicentric studies focusing on clinical endpoints are still warranted to determine the importance of omega-3 PUFA in CF therapeutics. RÉSUMÉ Les patients atteints de mucoviscidose (patients CF) souffrent d'infections pulmonaires récurrentes. Celles-ci provoquent un afflux permanent de neutrophiles dans le poumon, neutrophiles qui libèrent des enzymes protéolytiques et des radicaux libres responsables à long terme de la destruction du tissu pulmonaire et, finalement, de l'insuffisance respiratoire, première cause de morbidité et de mortalité chez ces patients. La réponse inflammatoire ainsi induite peut être réduite par divers traitements anti-inflammatoires, tels que corticoïdes, anti-inflammatoires non stéroïdiens ou azithromycine. L'apport oral en acides gras polyinsaturés (AGPI) oméga-3 pourrait être une autre approche thérapeutique intéressante. Ces nutriments sont décrits comme possédant des propriétés anti-inflammatoires notamment en favorisant la synthèse d'eicosanoïdes pourvus d'une activité inflammatoire moindre par rapport à ceux issus d'une autre famille d'AGPI, les oméga-6. Ce travail de thèse a pour objectif premier d'évaluer l'impact de cette approche nutritionnelle sur diverses fonctions du neutrophile chez des patients CF. Cependant un intérêt de nature prospective a également été porté à certains paramètres cliniques, afin d'évaluer la faisabilité d'une future étude axée sur des effets cliniques. Pour ce faire, une méthode de chromatographie liquide à haute performance couplée à un spectromètre de masse a été développée et validée. Cette analyse devait permettre le dosage simultané de deux eicosanoïdes, le leucotriène B4 (LTB4) issu des AGPI oméga-6 et le leucotriène B5 (LTB5) issu des AGPI oméga-3. Puis, une étude clinique, double aveugle, randomisée, croisée sans période de washout, mais contrôlée avec un placebo, a été mise au point pour évaluer l'effet immunomodulateur de ces AGPI oméga-3 donnés sous la forme d'un liquide nutritif chez des patients CF. Les résultats de cette étude ont permis de démontrer l'absorption intestinale des AGPI oméga-3 par les patients. De plus, leur administration a permis de modifier la production de teucotriène B. En effet, le ratio LTB4/LTB5 a été diminué de près de trois fois sous liquide nutritif enrichi en AGPI oméga-3. Enfin aucune différence n'a pu être notée pour les paramètres cliniques; toutefois les résultats reproductibles observés permettent d'envisager qu'une future étude multicentrique axée sur des effets cliniques est faisable. En conclusion, la modification de la composition en AGPI membranaires du neutrophile observée durant cette étude laisse penser que ces nutriments sont absorbés par les patients CF. La modulation de la production en LTBs qui en découle permet d'envisager un potentiel effet anti-inflammatoire. Toutefois, la relevance clinique de ces observations restent à être démontrée. A l'heure actuelle, une étude multicentrique, focalisée sur des paramètres cliniques, est nécessaire avant de pouvoir se prononcer sur l'utilisation des AGPI oméga-3 chez les patients CF.

Accompagnement thérapeutique : le chemin du suivi à long terme [Patient education: the way for long-term follow up]

L'éducation thérapeutique du patient est maintenant parfaitement intégrée dans les soins. Son champ d'application se situe essentiellement dans le domaine des maladies chroniques pour l'acquisition de compétences dans la gestion du traitement, en coopération avec les professionnels. En médecine ambulatoire, patients et soignants se heurtent actuellement aux difficultés du suivi avec sa part d'incertitude, lassitude et de pression économique. La médecine fondée sur les preuves (EBM) et les différents modèles en psychologie de la santé ne nous éclairent que partiellement le chemin. Un nouveau type de démarche réflexive est en train d'émerger. Cette réflexion devrait placer en son centre la notion de relation thérapeutique : entre science et existence. Nous résumons ici ce processus réflexif en cours d'une équipe interdisciplinaire regroupant sciences humaines, art et médecine. Therapeutic education is now perfectly integrated in caring and medicine. Its field of application is primarily in chronic diseases for the acquisition of competences in the management of treatments, in co-operation with health professionals. In ambulatory medicine, patients and health professionals are currently running up against the difficulties of the long-term follow-up with its part of uncertainty, lassitude and economic pressure. EBM and the various models of health psychology light us only partially the way. A new type of reflexive step is emerging. This way of thinking should place in its center the concept of therapeutic relation: between science and being. We summarize here our reflexive process in the course of an interdisciplinary team gathering social sciences, art and medicine

Potential of education-based insulin therapy for achievement of good metabolic control: a real-life experience.

Diabet. Med. 28, 539-542 (2011) ABSTRACT: Aims  Achievement of good metabolic control in Type 1 diabetes is a difficult task in routine diabetes care. Education-based flexible intensified insulin therapy has the potential to meet the therapeutic targets while limiting the risk for severe hypoglycaemia. We evaluated the metabolic control and the rate of severe hypoglycaemia in real-life clinical practice in a centre using flexible intensified insulin therapy as standard of care since 1990. Methods  Patients followed for Type 1 diabetes (n = 206) or those with other causes of absolute insulin deficiency (n = 17) in our outpatient clinic were analysed in a cross-sectional study. Mean age (± standard deviation) was 48.9 ± 15.7 years, with diabetes duration of 21.4 ± 14.4 years. Outcome measures were HbA(1c) and frequency of severe hypoglycaemia. Results  Median HbA(1c) was 7.1% (54 mmol/mol) [interquartile range 6.6-7.8 (51-62 mmol/mol)]; a good or acceptable metabolic control with HbA(1c) < 7.0% (53 mmol/mol) or 7.5% (58 mmol/mol) was reached in 43.5 and 64.6% of the patients, respectively. The frequency of severe hypoglycaemic episodes was 15 per 100 patient years: 72.3% of the patients did not experience any such episodes during the past 5 years. Conclusions  Good or acceptable metabolic control is achievable in the majority of patients with Type 1 diabetes or other causes of absolute insulin deficiency in routine diabetes care while limiting the risk for severe hypoglycaemia.

The function of natural killer cells: education, reminders and some good memories.

The effector response of natural killer (NK) cells is determined by opposing signals received through activating and inhibitory receptors. A process termed NK cell education, which is guided by the recognition of Major Histocompatibility Complex class I (MHC-I) molecules, determines how efficiently activating receptors respond to stimulation. This ensures NK cell tolerance to healthy tissues while allowing robust responses to diseased host cells. It was thought that NK cells are educated during their development in the bone marrow and that education fixes the NK cells' functional properties. However, recent findings suggest that the function of mature peripheral NK cells can adapt to changes in their environment and that the persistent exposure to normal-self is essential to maintain NK cell reactivity. Notwithstanding, NK cell stimulation in the context of inflammation can stably improve the functional properties of NK cells.
