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.

A Pensão dos Idosos e a Protecção na Velhice Caso dos Idosos de Santa Catarina de Santiago

Para a realização do presente trabalho, intitulado“A Pensão dos Idosos e a Protecção na Velhice” Caso dos Idosos de Santa Catarina de Santiago, analisou-se a problemática da 3ª idade, as dificuldades enfrentadas no dia-a-diados idosos em Santa Catarina, as vulnerabilidades, o tratamento que lhes é dado no seio familiar, no meio social, assim como o impacto que a pensão social tem nas suas vidas. Foi utilizado a metodologia de recolha documental, bem como a análise e tratamento de dados disponibilizados pelo Instituto Nacional de Estatística, Câmara Municipal de Santa Catarina, Instituto Nacional de Previdência Social, Centro de Desenvolvimento Social e Centro Nacional de Pensão Social. Realizou-se ainda entrevistas, com base num guião semi-estruturado e laborado para o efeito. Este estudo realça a realidade dos pensionistas de Santa Catarina, tantoos do regimecontributivo como os do regime não contributivo. A maioria dos idosos usufruem de umapensão, em que no regime geral temos 130 pessoas que recebem através do INPS, 64 delesrecebem uma pensão por velhice, cerca de 14 pessoas recebem uma pensão por invalidez, 51 pessoas recebem uma pensão de sobrevivência e apenas uma tem uma pensão complementar.Temos cerca de 1.614que são pensionistas de convenção, (trabalhadores migrantes), e um total de 2.054 pensionistas, pertencente ao regime não contributivo. A discussão e análise dos resultados confirmam as hipóteses, concluindo que as políticas sociais que sustentam a pensão dos idosos têm tido um forte impacto na família e na sociedade ajudando a combater a pobreza, exclusão e desigualdades sociais, melhorando a qualidade de vida destes e dando-lhes mais segurança e protecção.

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.

O enfermeiro e o amputado: a qualidade de vida do utente amputado o membro inferior

O presente estudo foi elaborado no âmbito da disciplina de Seminários Avançados em Enfermagem I e Investigação Científica. Desenvolveu-se uma investigação de cariz qualitativa, cujo objectivo geral foi o de analisar se as intervenções de enfermagem promovem a qualidade de vida do utente amputado o membro inferior no serviço da Cirurgia do Hospital Baptista de Sousa, recorrendo-se para o efeito a entrevistas semiestruturadas e a observação participante a sete enfermeiros do serviço. O conceito amputação veio sofrendo transformações desde a antiguidade, onde a prática do procedimento era feita de forma rudimentar, baseada apenas numa cirurgia sem nenhum cuidado. Surge então o interesse em tentar compreender e identificar o significado da qualidade de vida nas pessoas sujeitas a uma amputação e verificar a interferência dos cuidados sobre a qualidade de vida das mesmas durante o período de internamento na perspectiva do enfermeiro. Várias são as causas que podem levar a amputação do membro inferior e uma das principais é a Diabetes Mellitus, sendo que esta era considerada uma doença dos idosos, porque atingia mais a camada idosa. No entanto o que se verifica é que hoje esta doença tem vindo a atingir cada vez mais os jovens devido aos comportamentos de risco, como o tabagismo, o uso abusivo do álcool, o sedentarismo, entre outros. Com a presente investigação chegou-se a conclusão que de facto os enfermeiros do serviço de Cirurgia detêm conhecimentos técnicos e científicos para cuidar do utente amputado, conhecem os preceitos ligados a temática qualidade de vida, mas no entanto nos cuidados diários não se evidencia uma qualidade máxima na sua prestação. Os cuidados são básicos de forma geral, não havendo uma especificação quando o cuidar é para uma pessoa amputada o membro inferior. Salienta-se também que o espaço do serviço revela-se insuficiente para garantir uma maximização dessa qualidade de vida durante o internamento, bem como os recursos materiais e humanos. Todavia graças ao sistema, designada enfermagem de proximidade, os enfermeiros têm tarefas específicas, acabando por ficar mais tempo junto dos utentes, o que facilita na melhoria futura dessa qualidade de vida dos utentes internados.

Assistência de enfermagem aos idosos com fractura do colo do fémur

O presente trabalho intitulado “Assistência de enfermagem ao idoso com fractura do colo do fémur” tem como objectivo geral “Verificar se os cuidados de enfermagem prestados aos idosos com fracturas do colo do fémur internados no serviço de orto-traumatologia no Hospital Baptista de Sousa satisfazem as necessidades desses utentes. Sentiu-se a necessidade de expor este tema visto que é um acontecimento que afecta sobretudo os idosos, e leva-nos a entender melhor os cuidados a ter com eles, visto que com o avançar da idade ficam predispostos a várias doenças. Com o avançar dos anos a esperança média de vida vem aumentando, e as novas tecnologias ganhando grandes avanços, podendo proporcionar aos idosos um cuidado de qualidade. O método utilizado foi a entrevista semiestruturada, tratando-se de uma abordagem qualitativa de carácter fenomenológico. Foi entrevistado 7 enfermeiros, e com as entrevistas feitas notou-se que alguns enfermeiros que trabalham no serviço de Orto-traumatologia devido aos vários anos de experiencia obtêm um vasto conhecimento sobre a área. Os resultados da pesquisa apontam que os enfermeiros entrevistados têm conhecimento de como prestar uma boa assistência de enfermagem aos idosos com fractura do colo do fémur, mas devido as limitações dos recursos materiais e humanos não conseguem garantir a satisfação das necessidades humanas desses idosos na totalidade, visto que o tempo e o número de enfermeiros é insuficiente para garantir um cuidado de qualidade onde frisam satisfazer parcialmente essas necessidades. Ainda a outros enfermeiros que afirmam que se tivesse pelo menos mais alguns profissionais de saúde poderiam dar melhores respostas a essas necessidades, no entanto fazem o melhor com os recursos que tem.

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).

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.

Fuel metabolism during exercise in euglycaemia and hyperglycaemia in patients with type 1 diabetes mellitus--a prospective single-blinded randomised crossover trial.

Aims/hypothesis We assessed systemic and local muscle fuel metabolism during aerobic exercise in patients with type I diabetes at euglycaemia and hyperglycaemia with identical insulin levels.Methods This was a single-blinded randomised crossover study at a university diabetes unit in Switzerland. We studied seven physically active men with type I diabetes (mean +/- SEM age 33.5 +/- 2.4 years, diabetes duration 20.1 +/- 3.6 years, HbA(1c) 6.7 +/- 0.2% and peak oxygen uptake [VO2peak] 50.3 +/- 4.5 ml min(-1) kg(-1)). Men were studied twice while cycling for 120 min at 55 to 60% of VO2peak, with a blood glucose level randomly set either at 5 or 11 mmol/l and identical insulinaemia. The participants were blinded to the glycaemic level; allocation concealment was by opaque, sealed envelopes. Magnetic resonance spectroscopy was used to quantify intramyocellular glycogen and lipids before and after exercise. Indirect calorimetry and measurement of stable isotopes and counter-regulatory hormones complemented the assessment of local and systemic fuel metabolism.Results The contribution of lipid oxidation to overall energy metabolism was higher in euglycaemia than in hyperglycaemia (49.4 +/- 4.8 vs 30.6 +/- 4.2%; p<0.05). Carbohydrate oxidation accounted for 48.2 +/- 4.7 and 66.6 +/- 4.2% of total energy expenditure in euglycaemia and hyperglycaemia, respectively (p<0.05). The level of intramyocellular glycogen before exercise was higher in hyperglycaemia than in euglycaemia (3.4 +/- 0.3 vs 2.7 +/- 0.2 arbitrary units [AU]; p<0.05). Absolute glycogen consumption tended to be higher in hyperglycaemia than in euglycaemia (1.3 +/- 0.3 vs 0.9 +/- 0.1 AU). Cortisol and growth hormone increased more strongly in euglycaemia than in hyperglycaemia (levels at the end of exercise 634 52 vs 501 +/- 32 nmol/l and 15.5 +/- 4.5 vs 7.4 +/- 2.0 ng/ml, respectively; p<0.05).Conclusions/interpretation Substrate oxidation in type I diabetic patients performing aerobic exercise in euglycaemia is similar to that in healthy individuals revealing a shift towards lipid oxidation during exercise. In hyperglycaemia fuel metabolism in these patients is dominated by carbohydrate oxidation. Intramyocellular glycogen was not spared in hyperglycaemia.

No consistent association between processes-of-care and health-related quality of life among patients with diabetes : a missing link?

PURPOSE: Health-related quality of life (HRQoL) is considered a representative outcome in the evaluation of chronic disease management initiatives emphasizing patient-centered care. We evaluated the association between receipt of processes-of-care (PoC) for diabetes and HRQoL. METHODS: This cross-sectional study used self-reported data from non-institutionalized adults with diabetes in a Swiss canton. Outcomes were the physical/mental composites of the short form health survey 12 (SF-12) physical composite score, mental composite score (PCS, MCS) and the Audit of Diabetes-Dependent Quality of Life (ADDQoL). Main exposure variables were receipt of six PoC for diabetes in the past 12 months, and the Patient Assessment of Chronic Illness Care (PACIC) score. We performed linear regressions to examine the association between PoC, PACIC and the three composites of HRQoL. RESULTS: Mean age of the 519 patients was 64.5 years (SD 11.3); 60% were male, 87% reported type 2 or undetermined diabetes and 48% had diabetes for over 10 years. Mean HRQoL scores were SF-12 PCS: 43.4 (SD 10.5), SF-12 MCS: 47.0 (SD 11.2) and ADDQoL: -1.6 (SD 1.6). In adjusted models including all six PoC simultaneously, receipt of influenza vaccine was associated with lower ADDQoL (β=-0.4, p≤0.01) and foot examination was negatively associated with SF-12 PCS (β=-1.8, p≤0.05). There was no association or trend towards a negative association when these PoC were reported as combined measures. PACIC score was associated only with the SF-12 MCS (β=1.6, p≤0.05). CONCLUSIONS: PoC for diabetes did not show a consistent association with HRQoL in a cross-sectional analysis. This may represent an effect lag time between time of process received and health-related quality of life. Further research is needed to study this complex phenomenon.

Diabète et insuffisance rénate terminate. Evolution en huit ans dans le canton de Vaud [Diabetes and end stage renal disease. Eight year progression in the Canton de Vaud, Switzerland].

Diabetic nephropathy is the first cause of endstage renal disease. The demographic expansion, the increase in the incidence of diabetes and the prolonged survival rates explain the steep increase observed these last 30 years. In the United States, improved treatment has brought to a decline in the incidence of end-stage renal disease in the diabetic population since the mid nineties. We examined the change in prevalence of diabetics on dialysis from 2001 and 2009 in the Canton de Vaud, Switzerland. The prevalence of diabetics on dialysis increased from 18% to 31% in dialysis centers and increased from 1.1/1000 to 1.9/1000 in the diabetic population. These are strong indicators that efforts are needed to improve the renal outcome of patients with diabetic nephropathy.

Mortality associated with diabetes mellitus in comparison with history of cardiovascular disease in older women.

BACKGROUND: Women with diabetes mellitus have an increased risk of cardiovascular disease (CVD) mortality and current treatment guidelines consider diabetes to be equivalent to existing CVD, but few data exist about the relative importance of these risk factors for total and cause-specific mortality in older women. METHODS: We studied 9704 women aged ≥65 years enrolled in a prospective cohort study (Study of Osteoporotic Fractures) during a mean follow-up of 13 years and compared all-cause, CVD and coronary heart disease (CHD) mortality among non-diabetic women without and with a prior history of CVD at baseline and diabetic women without and with a prior history of CVD. Diabetes mellitus and prior CVD (history of angina, myocardial infarction or stroke) were defined as self-report of physician diagnoses. Cause of death was adjudicated from death certificates and medical records when available (>95% deaths confirmed). Ascertainment of vital status was 99% complete. Log-rank tests for the rates of death and multivariate Cox hazard models adjusted for age, smoking, physical activity, systolic blood pressure, waist girth and education were used to compare mortality among the four groups with non-diabetic women without CVD as the referent group. Results are reported as adjusted hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: At baseline mean age was 71.7±5.3 years, 7.0% reported diabetes mellitus and 14.5% reported prior CVD. 4257 women died during follow-up, 36.6% were attributed to CVD. The incidence of CVD death per 1000 person-years was 9.9 and 21.6 among non-diabetic women without and with CVD, respectively, and 23.8 and 33.3 among diabetic women without and with CVD, respectively. Compared to nondiabetic women without prior CVD, the risk of CVD mortality was elevated among both non-diabetic women with CVD (HR=1.82, CI: 1.60-2.07, P<0.001) and diabetic women without prior CVD (HR=2.24, CI: 1.87-2.69, P<0.001). CVD mortality was highest among diabetic women with CVD (HR=3.41, CI: 2.61-4.45, P<0.001). Compared to non-diabetic women with CVD, diabetic women without prior CVD had a significantly higher adjusted HR for total and CVD mortality (P<0.001 and P<0.05 respectively). CHD mortality did not differ significantly between non-diabetic women with CVD and diabetic women without prior CVD. CONCLUSION: Older diabetic women without prior CVD have a higher risk of all-cause and CVD mortality and a similar risk of CHD mortality compared to non-diabetic women with pre-existing CVD. For older women, these data support the equivalence of prior CVD and diabetes mellitus in current guidelines for the prevention of CVD.
