La psoriasis es una enfermedad que se caracteriza por un proceso inflamatorio crónico y exagerado local y sistémico. Se ha encontrado en la literatura una relación entre la psoriasis y el desarrollo de patologías como diabetes mellitus tipo 2 y el mal control de estas patologías, lo cual aumenta la morbimortalidad de estos pacientes. El presente estudio mostró que no se encontró asociación entre psoriasis y el control de la DM2 , y que la variable mas significativa sobre el control es la adherencia al tratamiento hipoglicemiante.

El riesgo cardiovascular, definido como la probabilidad de presentar un evento en un periodo determinado, se puede determinar con base a un estudio muy utilizado, el estudio de Framingham. Se llevó a cabo un estudio corte transversal en 102 conductores para establecer la relación entre actividad física, y el riesgo de desarrollar enfermedad coronaria y diabetes mellitus. Se exploraron posibles asociaciones entre variables, utilizando la prueba de independencia Chi cuadrado de Mantel-Haenszel, y el test exacto de Fisher. Se encontró un riesgo de presentar un evento coronario en su mayoría bajo con un 77% de la población, se evidenció en un riesgo no mayor a 3% (bajo) representado por el 78% de la población. Sin embargo, 22 trabajadores del total, tienen un grado mayor al 3% de riesgo de desarrollar diabetes mellitus a 8 años. En la actualidad el impacto de la actividad física en la prevención y tratamiento de enfermedades cardiovasculares y de la diabetes mellitus es consistente, por lo que se debe enfatizar la promoción de la actividad física como parte fundamental de los esquemas terapéuticos para dichas enfermedades

Knowledge of the differences between the amounts and types of protein that are expressed in diseased compared to healthy subjects may give an understanding of the biological pathways that cause disease. This is the reasoning behind the presented protocol, which uses difference gel electrophoresis to discover up‐ or down‐regulated proteins between mice of different genotypes, or of those fed on different diets, that may thus be prone to develop diabetes‐like phenotypes. Subsequent analysis of these proteins by tandem mass spectrometry typically facilitates their identification with a high degree of confidence.

Peroxisome proliferator-activated receptor-gamma2 (PPARG2) is a nuclear hormone receptor of ligand-dependent transcription factor involved in adipogenesis and a molecular target of the insulin sensitizers thiazolidinediones. We addressed the question of whether the 3 variants (-1279G/A, Pro12Ala, and His478His) in the PPARG2 gene are associated with type 2 diabetes mellitus and its related traits in a South Indian population. The study subjects (1000 type 2 diabetes mellitus and 1000 normal-glucose-tolerant subjects) were chosen randomly from the Chennai Urban Rural Epidemiology Study, an ongoing population-based study in southern India. The variants were screened by single-stranded conformational variant, direct sequencing, and restriction fragment length polymorphism. Linkage disequilibrium was estimated from the estimates of haplotypic frequencies. The -1279G/A, Pro12Ala, and His478His variants of the PPARG2 gene were not associated with type 2 diabetes mellitus. However, the 2-loci analyses showed that, in the presence of Pro/Pro genotype of the Pro12Ala variant, the -1279G/A promoter variant showed increased susceptibility to type 2 diabetes mellitus (odds ratio, 2.092; 95% confidence interval, 1.22-3.59; P = .008), whereas in the presence of 12Ala allele, the -1279G/A showed a protective effect against type 2 diabetes mellitus (odds ratio, 0.270; 95% confidence interval, 0.15-0.49; P < .0001). The 3-loci haplotype analysis showed that the A-Ala-T (-1279G/A-Pro12Ala-His478His) haplotype was associated with a reduced risk of type 2 diabetes mellitus (P < .0001). Although our data indicate that the PPARG2 gene variants, independently, have no association with type 2 diabetes mellitus, the 2-loci genotype analysis involving -1279G/A and Pro12Ala variants and the 3-loci haplotype analysis have shown a significant association with type 2 diabetes mellitus in this South Indian population.

Genes play an important role in the development of diabetes mellitus. Putative susceptibility genes could be the key to the development of diabetes. Type 1 diabetes mellitus is one of the most common chronic diseases of childhood. A combination of genetic and environmental factors is most likely the cause of Type 1 diabetes. The pathogenetic sequence leading to the selective autoimmune destruction of islet beta-cells and development of Type 1 diabetes involves genetic factors, environmental factors, immune regulation and chemical mediators. Unlike Type 1 diabetes mellitus, Type 2 diabetes is often considered a polygenic disorder with multiple genes located on different chromosomes being associated with this condition. This is further complicated by numerous environmental factors which also contribute to the clinical manifestation of the disorder in genetically predisposed persons. Only a minority of cases of type 2 diabetes are caused by single gene defects such as maturity onset diabetes of the young (MODY), syndrome of insulin resistance (insulin receptor defect) and maternally inherited diabetes and deafness (mitochondrial gene defect). Although Type 2 diabetes mellitus appears in almost epidemic proportions our knowledge of the mechanism of this disease is limited. More information about insulin secretion and action and the genetic variability of the various factors involved will contribute to better understanding and classification of this group of diseases. This article discusses the results of various genetic studies on diabetes with special reference to Indian population.

Diabetes mellitus is the most common endocrine disturbance of domestic carnivores and can cause autonomic neurological disorders, although these are still poorly understood in veterinary medicine. There is little information available on the quantitative adaptation mechanisms of the sympathetic ganglia during diabetes mellitus in domestic mammals. By combining morphometric methods and NADPH-diaphorase staining (as a possible marker for nitric oxide producing neurons), type I diabetes mellitus-related morphoquantitative changes were investigated in the celiac ganglion neurons in dogs. Twelve left celiac ganglia from adult female German shepherd dogs were examined: six ganglia were from non-diabetic and six from diabetic subjects. Consistent hypertrophy of the ganglia was noted in diabetic animals with increase of 55% in length, 53% in width, and 61.5% in thickness. The ordinary microstructure of the ganglia was modified leading to an uneven distribution of the ganglionic units and a more evident distribution of axon fascicles. In contrast to non-diabetic dogs, there was a lack of NADPH-diaphorase perikarial labelling in the celiac ganglion neurons of diabetic animals. The morphometric study showed that both the neuronal and nuclear sizes were significantly larger in diabetic dogs (1.3 and 1.39 times, respectively). The profile density and area fraction of NADPH-diaphorase-reactive celiac ganglion neurons were significantly larger (1.35 and 1.48 times, respectively) in non-diabetic dogs compared to NADPH-diaphorase-non-reactive celiac ganglion neurons in diabetic dogs. Although this study suggests that diabetic neuropathy is associated with neuronal hypertrophy, controversy remains over the possibility of ongoing neuronal loss and the functional interrelationship between them. It is unclear whether neuronal hypertrophy could be a compensation mechanism for a putative neuronal loss during the diabetes mellitus. (C) 2007 Elsevier Ltd. All rights reserved.

Background. Microencapsulation of pancreatic islets with polymeric compounds constitutes an attractive alternative therapy for type 1 diabetes mellitus. The major limiting factor is the availability of a biocompatible and mechanically stable polymer. We investigated the potential of Biodritin, a novel polymer constituted of alginate and chondroitin sulfate, for islet microencapsulation. Methods. Biodritin microcapsules were obtained using an air jet droplet generator and gelated with barium or calcium chloride. Microencapsulated rat insulinoma RINm5F cells were tested for viability using the [3-(4,5-dimetyl-thiazol-2-yl)-2,5-diphenyl-tetrazoliumbromide] [MTT] colorimetric assay. Microencapsulated rat pancreatic islets were coincubated with macrophages derived from mouse peritoneal liquid to assess the immunomodulatory potential of the microcapsules, using quantitative real time-PCR (qPCR). Biodritin biocompatibility was demonstrated by subcutaneous injection of empty microcapsules into immunocompetent Wistar rats. Insulin secretion by microencapsulated human pancreatic islets was evaluated using an electrochemoluminescent assay. Microencapsulated human islets transplanted into chemically induced diabetic mice were monitored for reversal of hyperglycemia. Results. The metabolic activity of microencapsulated RINm5F cells persisted for at least 15 days. Interleukin-1 beta expression by macrophages was observed during coculture with islets microencapsulated with Biodritin-CaCl2, but not with Biodritin-BaCl2. No statistical difference in glucose-stimulated insulin secretion was observed between nonencapsulated and microencapsulated islets. Upon microencapsulated islet transplantation, the blood glucose level of diabetic mice normalized; they remained euglycemic for at least 60 days, displaying normal oral glucose tolerance tests. Conclusion. This study demonstrated that Biodritin can be used for islet microencapsulation and reversal of diabetes; however, further investigations are required to assess its potential for long-term transplantation.

Syftet med denna studie har varit att beskriva hur barn med diagnosen diabetes mellitus typ 1 upplever sin sjukdom samt vilken betydelse sjuksköterskan kunde ha i omvårdnaden av dessa barn. Studien har utförts som en systematisk litteraturstudie och tillvägagångssättet har varit att systematiskt söka, kritiskt granska och sammanställa resultat inom det valda ämnesområdet från olika studier. Sökningen har skett i databaserna Elin@Dalarna, Cinahl och Blackwell Synergy. Sökorden som har använts var: diabetes mellitus type 1, diabetes mellitus, children, adolescents, experiences, perspective, nurs* och care i olika kombinationer. Sammanställningen från resultatet visade att barn med diagnosen diabetes mellitus typ 1 upplever sin sjukdom olika utifrån sina egna förutsättningar, kön eller ålder. Det framkom även att sjuksköterskan hade en viktig roll när det gällde att fånga upp barnens upplevelser kring den förändrade livssituationen som uppstått och utifrån detta kartlägga barnens resurser att hantera denna situation. Att då kunna bemöta barnen och deras familjer utifrån egna förutsättningar och att motivera dessa till att sköta den livslånga behandlingen, kan vara avgörande för att få en bra kontroll över diabetes och på så sätt en ökad livskvalité och ett gott välbefinnande.

Syfte: Syftet med denna studie var att undersöka hur patienter upplevde patient-undervisningen samt hur sjuksköterskans roll såg ut i patientundervisningen. Metod: Uppsatsen har genomförts som en systematisk litteraturstudie. Artiklar har sökts i databaserna ELIN samt Cinahl. Artiklar publicerade mellan 1999-2009 och som var tillgängliga i fulltext inkluderades i resultatdelen som omfattade 14 kvalitativa studier samt en litteraturstudie. Resultat: I resultatet framgick att patienterna upplevde att gruppundervisning var ett bra alternativ till enskild undervisning då de kunde ta del av andras erfarenheter och på det sättet få mer kunskap om sjukdomen. Dessutom upplevde de att det var givande att träffa personer med samma sjukdom. I studien framgick att enskild undervisning var önskvärt från både patienter och sjuksköterskor då det kunde upplevas lättare att ta upp de frågor de hade där. Sjuksköterskan kunde vara ett stort stöd för patienten. Förutom att förmedla sina kunskaper och undervisa patienten var lyssna, uppmuntra och stötta något som sjuksköterskorna ansåg vara viktigt i mötet med patienten. Något som togs upp av patienter och sjuksköterskorna var att de ansåg att det vore bra om patienterna under besöken träffade samma personer då det skulle underlätta uppföljningarna.
