Training in flexible intensive insulin therapy improves quality of life, decreases the risk of hypoglycaemia and ameliorates poor metabolic control in patients with type 1 diabetes.

AIM: Intensified insulin therapy has evolved to be the standard treatment of type 1 diabetes. However, it has been reported to increase significantly the risk of hypoglycaemia. We studied the effect of structured group teaching courses in flexible insulin therapy (FIT) on psychological and metabolic parameters in patients with type 1 diabetes. METHODS: We prospectively followed 45 type 1 diabetic patients of our outpatient clinic participating in 5 consecutive FIT teaching courses at the University Hospital of Basel. These courses consist of 7 weekly ambulatory evening group sessions. Patients were studied before and 1, 6, and 18 months after the course. Main outcome measures were glycated haemoglobin (HbA1c), severe hypoglycaemic events, quality of life (DQoL), diabetes self-control (IPC-9) and diabetes knowledge (DWT). RESULTS: Quality of life, self-control and diabetes knowledge improved after the FIT courses (all p<0.001). The frequency of severe hypoglycaemic events decreased ten-fold from 0.33 episodes/6 months at baseline to 0.03 episodes/6 months after 18 months (p<0.05). Baseline HbA1c was 7.2+/-1.1% and decreased in the subgroup with HbA1c > or = 8% from 8.4% to 7.8% (p<0.05). CONCLUSIONS: In an unselected, but relatively well-controlled population of type 1 diabetes, a structured, but not very time consuming FIT teaching programme in the outpatient setting improves psychological well-being and metabolic parameters.

Killing by lung cancer or by diabetes? The trade-off between smoking and obesity

As the prevalence of smoking has decreased to below 20%, health practitioners interest has shifted towards theprevalence of obesity, and reducing it is one of the major health challenges in decades to come. In this paper westudy the impact that the final product of the anti-smoking campaign, that is, smokers quitting the habit, had onaverage weight in the population. To these ends, we use data from the Behavioral Risk Factors Surveillance System,a large series of independent representative cross-sectional surveys. We construct a synthetic panel that allows us tocontrol for unobserved heterogeneity and we exploit the exogenous changes in taxes and regulations to instrumentthe endogenous decision to give up the habit of smoking. Our estimates, are very close to estimates issued in the 90sby the US Department of Health, and indicate that a 10% decrease in the incidence of smoking leads to an averageweight increase of 2.2 to 3 pounds, depending on choice of specification. In addition, we find evidence that the effectovershoots in the short run, although a significant part remains even after two years. However, when we split thesample between men and women, we only find a significant effect for men. Finally, the implicit elasticity of quittingsmoking to the probability of becoming obese is calculated at 0.58. This implies that the net benefit from reducingthe incidence of smoking by 1% is positive even though the cost to society is $0.6 billions.

Traitements des facteurs de risque cardiovasculaire et dépistage de la maladie coronarienne dans le diabète de type 2 [Treatments for cardiovascular risk factors and screening for coronary artery disease in type 2 diabetes mellitus]

The recent ACCORD and DIAD studies revealed results which could modify treatments and the screening of diabetes vascular complications. Indeed, ACCORD shows no benefit on the prevention of diabetes vascular complications by aggressive treatment of hypertension or the combined treatment of the dyslipidemia. The intensive treatment of the blood glucose, if associated with severe hypoglycemias, increases mortality. DIAD revealed 20% of silent myocardial ischaemia in diabetic patients but no beneficial effect on the cardiovascular mortality. A careful reading of these studies in the light of long term studies such as UKPDS and STENO reveals that these negative results are generated by a too short follow-up and too aggressive objectives. The long term studies reveal that more realistic objectives remain beneficial.

Diabétologie [Diabetes].

The new recommendations on the pharmacological treatment of type 2 diabetes have introduced two important changes. The first is to have common strategies between European and American diabetes societies. The second, which is certainly the most significant, is to develop a patient centred approach suggesting therapies that take into account the patient's preferences and use of decision support tools. The individual approach integrates six factors: the capacity and motivation of the patient to manage his illness and its treatment, the risks of hypoglycemia, the life expectancy, the presence of co-morbidities and vascular complications, as well as the financial resources of the patient and the healthcare system. Treatment guidelines for cardiovascular risk reduction in diabetic remains the last point to develop.

Baseline data of a population-based cohort of patients with diabetes in Switzerland (CoDiab-VD)

QUESTIONS UNDER STUDY: To describe a population-based sample of patients with diabetes and the quality of their care in the canton of Vaud, Switzerland, as a baseline measure for the evaluation of the "Programme cantonal Diabète". METHODS: We conducted a self-administered paper-based questionnaire survey. Non-institutionalised adult (aged ≥18 years) patients with diabetes diagnosed for at least 1 year and residing in the canton of Vaud were recruited by community pharmacies. Women with gestational diabetes, people with obvious cognitive impairment or people not sufficiently fluent in French were excluded. Primary outcomes were recommended processes-of-care and outcomes of care (glycosylated haemoglobin [HbA1c], generic and disease-specific health-related quality of life (HRQoL), overall care score in relation to the Chronic Care Model). Other measures included diabetes education, self-management support and self-efficacy, health status, health behaviour and demographics. RESULTS: A total of 519 patients with diabetes were included. Whereas the mean HbA1c level was 7.3% (n = 177, 95% confidence interval 7.1-7.5), diabetes-specific processes-of-care and influenza vaccination were reported by less than two-thirds of the patients. Physical activity and diet recommendations results mirrored patients' difficulties with their management in daily life and diabetes-specific HRQoL was worst in the dimensions relative to diet (eating and drinking) and sex life. A minority of patients reported ever having participated in diabetes education courses (32.8%). Overall, patients were satisfied with their care and the support they received. CONCLUSIONS: This study provides a broad picture of the experiences of people living with diabetes in the canton of Vaud. It shall guide the development of targeted interventions within the "Programme cantonal Diabète".

History of diabetes and risk of head and neck cancer: a pooled analysis from the international head and neck cancer epidemiology consortium.

BACKGROUND: A history of diabetes is associated with an increased risk of several types of cancers. Whether diabetes is a risk factor for head and neck cancer (HNC) has received little attention. METHODS: We pooled data from 12 case-control studies including 6,448 cases and 13,747 controls, and estimated odds ratios (OR) and 95% confidence intervals (CI) for the associations between diabetes and HNC, adjusted for age, education level, sex, race/ethnicity, study center, cigarette smoking, alcohol use and body mass index (BMI). RESULTS: We observed a weak association between diabetes and the incidence of HNC overall (OR, 1.09; 95% CI, 0.95-1.24). However, we observed a modest association among never smokers (OR, 1.59; 95% CI, 1.22-2.07), and no association among ever smokers (OR, 0.96; 95% CI, 0.83-1.11); likelihood ratio test for interaction p=0.001. CONCLUSIONS: A history of diabetes was weakly associated with HNC overall, but we observed evidence of effect modification by smoking status, with a positive association among those who never smoked cigarettes. Impact: This study suggests that glucose metabolism abnormalities may be a HNC risk factor in subgroups of the population. Prospective studies incorporating biomarkers are needed to improve our understanding of the relationship between diabetes and HNC risk, possibly providing new strategies in the prevention of HNC.

Efeitos da Fisioterapia na Qualidade de Vida da mulher durante o Período Gestacional: Revisão Sistemática

Durante o período gestacional, a mulher passa por várias alterações anatómicas, fisiológicas e emocionais, que podem resultar em desconforto ou até mesmo dor, causando-lhe limitações durante a execução das suas atividades de vida diária, interferindo diretamente na sua qualidade de vida. É nesse contexto que a atuação fisioterapêutica assume uma grande importância, principalmente na diminuição dos desconfortos músculoesqueléticos presentes, contribuindo na preparação do corpo para o parto e no bem-estar geral. O presente estudo tem como objetivo analisar, através de uma revisão sistemática, os efeitos da fisioterapia na qualidade de vida de gestantes. Esta revisão consistiu numa busca de artigos publicados nas bases de dados PubMed, SciELO, MEDLINE e LILACS. Foram considerados como critérios de inclusão estudos experimentais e observacionais do tipo transversal e caso controlo, publicados em inglês ou português, entre 2002 a 2012, que abordam assuntos relacionados com o tema em referência. Durante a pesquisa foram localizados 56 títulos. Desses, apenas 15 artigos foram selecionados, sendo os mesmos submetidos à etapa de extração e análise de dados. A maioria dos artigos analisados apresentou relatos de melhoria na qualidade de vida, embora, isso não tenha sido estaticamente significativo em alguns estudos. Pode inferir-se que o acompanhamento fisioterapêutico durante a gestação parece reduzir a incidência de algias, controlar a ansiedade, melhorar a autoestima, também há indícios que pode trazer diversos benefícios músculoesqueléticos, podendo influenciar de uma forma positiva a QV de uma gestante. Vale salientar que é preciso aprimorar e desenvolver futuras pesquisas a respeito do papel da fisioterapia na atenção à saúde da mulher, com um rigor metodológico maior para que possa afirmar a sua efetividade especificamente na QV de gestantes.

Perception et communication du risque: du diabète à la maladie cardiovasculaire [Risk perception and communication: from diabetes to cardiovascular diseases].

Evidence-based medicine has enabled to approach disease in a more rational and scientific way. Clinical research has identified behaviours and risk factors that could cause disease often "silent" at the beginning, such as diabetes. Despite the clear impact of these evidences on public health, it seems that the individual risk perception level remains weak. To mention as well, the health professionals very often have a different views, which makes it difficult to communicate the risk with patients. In this article we describe the principles of risk perception, the diabetes related risk perception concerning cardiovascular complications, and suggest some practical strategies and tools which could improve risk communication in the everyday practice.

Perfil dos portadores de diabetes mellitus da Associação de Diabetes da Ilha de São Vicente

Sendo a Diabetes Mellitus (DM) uma patologia muito estigmatizada em todo o mundo, Cabo Verde não foge a regra, uma vez que esta patologia está presente no país em várias faixas etárias e classes sociais. Antigamente havia uma grande lacuna a nível de compreensão e entendimento da patologia, mas hoje porém, devido aos avanços da ciência médica em relação ao tratamento e ao seguimento, houve melhorias consideráveis. A DM constitui um grande problema de saúde pública a nível mundial não só pela crescente incidência das suas formas mais prevalentes, como também pela elevada morbilidade e mortalidade que lhe está associada. O objetivo principal do trabalho consente em descrever o perfil dos portadores da Diabetes na ilha de São Vicente, tendo em conta a saúde como um bem primário e fundamental, independentemente da condição social de qualquer portador. De entre as classificações da diabetes a DM2 é a mais prevalente, apresentando os fatores de riscos como a obesidade e mesmo naqueles com peso normal acarreta um maior controlo, evitando alterações de humor, profunda tristeza e nas complicações clínicas que poderão prejudicar o indivíduo. A metodologia utilizada neste trabalho foi qualitativa, através da realização de dezasseis entrevistas semiestruturadas, realizadas há dezasseis portadores da diabetes de ambos sexos e de faixas etárias diferentes na Associação de Diabetes de São Vicente. Destas entrevistas realizadas, foi possível constatar que os portadores da DM adquiram baixas habilitações académicas, o que interfere muito no conhecimento, na compreensão da sua patología e no baixo custo socioeconómico que não os ajuda no bom controlo da patología. Deste estudo vido constatar que a intervenção de enfermagem é crucial porque o enfermeiro surge como um agente transformador da consciência no quotidiano, na realização da prevenção e no tratamento da diabetes, possibilitando a continuação das actividades e da melhoria da Saúde. No ano de 2006 foi criado na Ilha de São Vicente a Associação da Diabetes com o propósito de auxiliar na prevenção, no tratamento e no controle dos portadores da DM, onde são inscritos cerca de 77 portadores, em que 29 do género masculino e 44 do género feminino, oriundos de diversas localidades da ilha (anexo I).

Hipoglucèmia neonatal en fills de mares que han presentat diabetis gestacional

La hipoglucèmia neonatal (HN) és un problema de salut freqüent en les primeres hores de vida del recent nascut (RN) especialment de mares que pateixen diabetis mellitus (DM) durant l’embaràs, més coneguda com a diabetis gestacional (DG). La diabetis gestacional és un dels principals factors de risc que condiciona a un nadó a presentar hipoglucèmia en les hores posteriors al naixement, per això, els professionals d’infermeria necessiten conèixer la millor manera d’atendre a la dona embarassada que pateix DG amb l’objectiu d’ensenyar-li unes cures personals especifiques per intentar disminuir la incidència de recent nascuts (RN) que presenten hipoglucèmia.

The gene MAPK8IP1, encoding islet-brain-1, is a candidate for type 2 diabetes.

Type 2 diabetes is a polygenic and genetically heterogeneous disease . The age of onset of the disease is usually late and environmental factors may be required to induce the complete diabetic phenotype. Susceptibility genes for diabetes have not yet been identified. Islet-brain-1 (IB1, encoded by MAPK8IP1), a novel DNA-binding transactivator of the glucose transporter GLUT2 (encoded by SLC2A2), is the homologue of the c-Jun amino-terminal kinase-interacting protein-1 (JIP-1; refs 2-5). We evaluated the role of IBi in beta-cells by expression of a MAPK8IP1 antisense RNA in a stable insulinoma beta-cell line. A 38% decrease in IB1 protein content resulted in a 49% and a 41% reduction in SLC2A2 and INS (encoding insulin) mRNA expression, respectively. In addition, we detected MAPK8IP1 transcripts and IBi protein in human pancreatic islets. These data establish MAPK8IP1 as a candidate gene for human diabetes. Sibpair analyses performed on i49 multiplex French families with type 2 diabetes excluded MAPK8IP1 as a major diabetogenic locus. We did, however, identify in one family a missense mutation located in the coding region of MAPK8IP1 (559N) that segregated with diabetes. In vitro, this mutation was associated with an inability of IB1 to prevent apoptosis induced by MAPK/ERK kinase kinase 1 (MEKK1) and a reduced ability to counteract the inhibitory action of the activated c-JUN amino-terminal kinase (JNK) pathway on INS transcriptional activity. Identification of this novel non-maturity onset diabetes of the young (MODY) form of diabetes demonstrates that IB1 is a key regulator of 3-cell function.

Connexins, diabetes and the metabolic syndrome.

Diabetes and the related metabolic syndrome are multi system disorders that result from improper interactions between various cell types. Even though the underlying mechanism remains to be fully understood, it is most likely that both the long and the short distance range cell interactions, which normally ensure the physiologic functioning of the pancreas, and its relationships with the insulin-targeted organs, are altered. This review focuses on the short-range type of interactions that depend on the contact between adjacent cells and, specifically, on the interactions that are dependent on connexins. The widespread distribution of these membrane proteins, their multiple modes of action, and their interactions with conditions/molecules associated to both the pathogenesis and the treatment of the 2 main forms of diabetes and the metabolic syndrome, make connexins an essential part of the chain of events that leads to metabolic diseases. Here, we review the present state of knowledge about the molecular and cell biology of the connexin genes and proteins, their general mechanisms of action, the roles specific connexin species play in the endocrine pancreas and the major insulin-targeted organs, under physiological and patho-physiological conditions.
