Angiosperm carpels are closed (sometimes barely so) saclike structures, sometimes with a long ventral stigmatic crest. Interpretation of winteraceous carpels, particularly those of Tasmannia (synonym Drimys sect. Tasmannia) piperita, has been critical to both ontogenetic and phylogenetic theories regarding general carpel development. Results from developmental studies in several Tasmannia species have suggested that, in this genus, carpels are congenitally fused. I investigated carpel development in Tasmannia insipida, a species closely related to T. piperita, using a replica technique to produce scanning electron micrographs indirectly from living material and anatomical sections from the same material after fixation; thus a surface and internal view of one and the same organ were obtained. Contrary to a previous report, I find that in T. insipida, carpel closure occurs late in development and is postgenital. The significant of having two different modes of carpel development in a single genus is discussed. 23 refs., 3 figs.

Aim To examine the phylogeography of Ficus insipida subsp. insipida in order to investigate patterns of spatial genetic structure across the Neotropics and within Amazonia. Location Neotropics. Methods Plastid DNA (trnH–psbA; 410 individuals from 54 populations) and nuclear ribosomal internal transcribed spacer (ITS; 85 individuals from 27 populations) sequences were sampled from Mexico to Bolivia, representing the full extent of the taxon's distribution. Divergence of plastid lineages was dated using a Bayesian coalescent approach. Genetic diversity was assessed with indices of haplotype and nucleotide diversities, and genetic structure was examined using spatial analysis of molecular variance (SAMOVA) and haplotype networks. Population expansion within Amazonia was tested using neutrality and mismatch distribution tests. Results trnH–psbA sequences yielded 19 haplotypes restricted to either Mesoamerica or Amazonia; six haplotypes were found among ITS sequences. Diversification of the plastid DNA haplotypes began c. 14.6 Ma. Haplotype diversity for trnH–psbA was higher in Amazonia. Seven genetically differentiated SAMOVA groups were described for trnH–psbA, of which two were also supported by the presence of unique ITS sequences. Population expansion was suggested for both markers for the SAMOVA group that contains most Amazonian populations. Main conclusions Our results show marked population genetic structure in F. insipida between Mesoamerica and Amazonia, implying that the Andes and seasonally dry areas of northern South America are eco-climatic barriers to its migration. This pattern is shared with other widespread pioneer species affiliated to wet habitats, indicating that the ecological characteristics of species may impact upon large-scale phylogeography. Ficus insipida also shows genetic structure in north-western Amazonia potentially related to pre-Pleistocene historical events. In contrast, evident population expansion elsewhere in Amazonia, in

The response of whole-plant water-use efficiency, termed transpiration efficiency (TE), to variation in soil fertility was assessed in a tropical pioneer tree, Ficus insipida Willd. Measurements of stable isotope ratios (delta(13)C, delta(18)O, delta(15)N), elemental concentrations (C, N, P), plant growth, instantaneous leaf gas exchange, and whole-plant water use were used to analyse the mechanisms controlling TE. Plants were grown individually in 19 l pots with non-limiting soil moisture. Soil fertility was altered by mixing soil with varying proportions of rice husks, and applying a slow release fertilizer. A large variation was observed in leaf photosynthetic rate, mean relative growth rate (RGR), and TE in response to experimental treatments; these traits were well correlated with variation in leaf N concentration. Variation in TE showed a strong dependence on the ratio of intercellular to ambient CO(2) mole fractions (c(i)/c(a)); both for instantaneous measurements of c(i)/c(a) (R(2)=0.69, P <0.0001, n=30), and integrated estimates based on C isotope discrimination (R(2)=0.88, P <0.0001, n=30). On the other hand, variations in the leaf-to-air humidity gradient, unproductive water loss, and respiratory C use probably played only minor roles in modulating TE in the face of variable soil fertility. The pronounced variation in TE resulted from a combination of the strong response of c(i)/c(a) to leaf N, and inherently high values of c(i)/c(a) for this tropical tree species; these two factors conspired to cause a 4-fold variation among treatments in (1-c(i)/c(a)), the term that actually modifies TE. Results suggest that variation in plant N status could have important implications for the coupling between C and water exchange in tropical forest trees.

Tropospheric ozone (O3) is a major air pollutant and greenhouse gas, affecting carbon dynamics, ecological interactions, and agricultural productivity across continents and biomes. Elevated [O3] has been documented in tropical evergreen forests, the epicenters of terrestrial primary productivity and plant-consumer interactions. However, the effects of O3 on vegetation have not previously been studied in these forests. In this study, we quantified ambient O3 in a region shared by forests and urban/commercial zones in Panama and found levels two to three times greater than in remote tropical sites. We examined the effects of these ambient O3 levels on the growth and chemistry of seedlings of Ficus insipida, a regionally widespread tree with high stomatal conductance, using open-top chambers supplied with ozone-free or ambient air. We evaluated the differences across treatments in biomass and, using UPLC-MS-MS, leaf secondary metabolites and membrane lipids. Mean [O3] in ambient air was below the levels that induce chronic stress in temperate broadleaved trees, and biomass did not differ across treatments. However, leaf secondary metabolites - including phenolics and a terpenoid - were significantly downregulated in the ambient air treatment. Membrane lipids were present at lower concentrations in older leaves grown in ambient air, suggesting accelerated senescence. Thus, in a tree species with high O3 uptake via high stomatal conductance, current ambient [O3] in Panamanian forests are sufficient to induce chronic effects on leaf chemistry.

Global warming and associated increases in the frequency and amplitude of extreme weather events, such as heat waves, may adversely affect tropical rainforest plants via significantly increased tissue temperatures. In this study, the response to two temperature regimes was assessed in seedlings of the neotropical pioneer tree species, Ficus insipida. Plants were cultivated in growth chambers at strongly elevated daytime temperature (39°C), combined with either close to natural (22°C) or elevated (32°C) nighttime temperatures. Under both growth regimes, the critical temperature for irreversible leaf damage, determined by changes in chlorophyll a fluorescence, was approximately 51°C. This is comparable to values found in F. insipida growing under natural ambient conditions and indicates a limited potential for heat tolerance acclimation of this tropical forest tree species. Yet, under high nighttime temperature, growth was strongly enhanced, accompanied by increased rates of net photosynthetic CO2 uptake and diminished temperature dependence of leaf-level dark respiration, consistent with thermal acclimation of these key physiological parameters.
Essential facts Type 1 and type 2 diabetes affect 3.2 million people in the UK. Diabetes is associated with serious complications, including heart disease and stroke, which can lead to disability and premature death. It is the leading cause of preventable sight loss in people of working age in the UK. A quarter of people with diabetes will have kidney disease at some point in their lives, and the condition increases the risk of amputation. Good diabetes management has been shown to reduce the incidence of these serious complications.
Pancreatologists have often divided research of the pancreas based upon the origin of the function or disease, namely the endocrine or exocrine pancreas. In fact, as a result, many of our meetings and conferences have followed separate paths. Interestingly, among patients with chronic pancreatitis and pancreatic cancer, both disorders of the exocrine pancreas, diabetes is common. However, the clinical features of the diabetes associated with these two differ. Peripheral insulin resistance and hyperinsulinemia are the predominant diabetic traits in pancreatic cancer, while reduced islet cell mass and impaired insulin secretion are observed more often in chronic pancreatitis. The causal relationship between diabetes and pancreatic cancer remains an intriguing but unanswered question. Since diabetes often precedes pancreatic cancer, it is regarded as a potential risk factor for malignancy. On the other hand, there remains the possibility that pancreatic cancer secretes diabetogenic factors. Regardless of how the science ultimately illuminates this issue, there is increasing interest in utilizing screening for diabetes to aid early detection of pancreatic tumor lesions. Therefore, in this issue of Pancreatology and the Web, we explore the topic of diabetes to keep us alert to this very important association, even if we study diseases of the exocrine pancreas.
A new study shows that statin therapy before diagnosis of diabetes mellitus is not associated with an increased risk of microvascular disease and might even be beneficial for retinopathy and neuropathy. These data suggest a potential protective effect of statins in specific complications, which should be further investigated in randomized controlled trials. PMID:25366041

Diabetic nephropathy without diabetes (DNND), previously known as idiopathic nodular glomerulosclerosis, is an uncommon entity and thus rarely suspected; diagnosis is histological once diabetes is discarded. In this study we describe two new cases of DNND and review the literature. We analyzed all the individualized data of previous publications except one series of attached data. DNND appears to be favored by recognized cardiovascular risk factors. However, in contrast with diabetes, apparently no factor alone has been demonstrated to be sufficient to develop DNND. Other factors not considered as genetic and environmental factors could play a role or interact. The most plausible hypothesis for the occurrence of DNND would be a special form of atherosclerotic or metabolic glomerulopathy than can occur with or without diabetes. The clinical spectrum of cardiovascular risk factors and histological findings support this theory, with hypertension as one of the characteristic clinical features. PMID:26239683

Diabetic neuropathy (DN) is the most common and troublesome complication of diabetes mellitus, leading to the greatest morbidity and mortality and resulting in a huge economic burden for diabetes care. The clinical assessment of diabetic peripheral neuropathy and its treatment options are multifactorial. Patients with DN should be screened for autonomic neuropathy, as there is a high degree of coexistence of the two complications. A review of the clinical assessment and treatment algorithms for diabetic neuropathy, painful neuropathy, and autonomic dysfunction is provided.

Diabetes mellitus is a group of diseases characterized by high levels of blood glucose resulting from defects in insulin production, insulin action, or both. Diabetes is a serious health concern. The number of cases of diabetes mellitus is estimated to grow at a rate of 50% between 2000 and 2010. There are several types of diabetes: type 1 diabetes, type 2 diabetes, gestational diabetes, and other specific types of diabetes. Beta cell dysfunction plays a key role in the physiopathology of diabetes, even when insulin resistance, which is often present in several diabetes-related diseases, is considered among the causes of hyperglycemic type 2 diabetes. The prolonged hyperglycemia that is peculiar to all kind of diabetes has long term complications on several organs and systems. The diagnosis of diabetes is based on the evaluation of glucose plasma levels performed under fasting conditions or two hours after the oral ingestion of 75 grams of glucose. Currently, achieving and maintaining normal plasma levels of glucose are the aims of therapy for both type 1 and type 2 diabetes. Particularly, the therapy for type 1 diabetes is based on the administration of insulin, whereas that of type 2 diabetes changes over the time: diet and physical activity are the first treatments; oral hypoglycemic drugs are used as a second therapeutic step; and the administration of insulin is the last therapeutic option. The principal therapeutic innovation of the past ten years is represented by the tight and flexible control of glucose plasma level obtained by using the insulin analogues produced by recombinant DNA technology.

Diabetes is the most common cause of peripheral neuropathy in the world. Both type 1 (insulin-dependent) and type 2 diabetes are commonly complicated by peripheral nerve disorders. Two main types of neuropathy are observed: the most common is a nerve fiber length-dependent, distal symmetrical sensory polyneuropathy with little motor involvement but frequent, and potentially life threatening, autonomic dysfunction. Alteration of temperature and pain sensations in the feet is an early manifestation of diabetic polyneuropathy. The second pattern is a focal neuropathy, which more commonly complicates or reveals type 2 diabetes. Poor diabetic control increases the risk of neuropathy with subsequent neuropathic pains and trophic changes in the feet, which can be prevented by education of patients.

During the past several decades, the number of both business and tourist travels has greatly increased. Among them are persons suffering from chronic diseases, including diabetics for whom travels pose the additional health-hazard. Irrespective of better education, self-control and constantly improving quality of specialistic equipment available, diabetics still are the group of patients requiring particular attention. In the case of travelling diabetics, problems may occur concerning the transport and storage of insulin, as well as control of glycaemia, all caused by irregularity of meals, variable diet, physical activity, stress, kinetosis (sea voyages), and the change of time zones. The travel may as well evoke ailments caused by the change of climate and concomitant diseases such as traveller's diarrhoea, malaria, etc. Apart from avoiding glycaemia fluctuations, important for retaining health of diabetics is the prevention of other diseases and carrying the necessary drugs.

Diabetic neuropathy (DN) refers to symptoms and signs of neuropathy in a patient with diabetes in whom other causes of neuropathy have been excluded. Distal symmetrical neuropathy is the commonest accounting for 75% DN. Asymmetrical neuropathies may involve cranial nerves, thoracic or limb nerves; are of acute onset resulting from ischaemic infarction of vasa nervosa. Asymmetric neuropathies in diabetic patients should be investigated for entrapment neuropathy. Diabetic amyotrophy, initially considered to result from metabolic changes, and later ischaemia, is now attributed to immunological changes. For diagnosis of DN, symptoms, signs, quantitative sensory testing, nerve conduction study, and autonomic testing are used; and two of these five are recommended for clinical diagnosis. Management of DN includes control of hyperglycaemia, other cardiovascular risk factors; α lipoic acid and L carnitine. For neuropathic pain, analgesics, non‐steroidal anti‐inflammatory drugs, antidepressants, and anticonvulsants are recommended. The treatment of autonomic neuropathy is symptomatic. PMID:16461471

Diabetes insipidus is an uncommon disorder of water-electrolyte balance characterized by the excretion of abnormally large volumes of diluted urine (polyuria) and increased fluid intake (polydipsia). The disease may result from the insufficient production of vasopressin, its increased degradation, an impaired response of kidneys to vasopressin, or may be secondary to excessive water intake. Patients with severe and uncompensated symptoms may develop marked dehydration, neurologic symptoms and encephalopathy, and therefore diabetes insipidus can be a life-threatening condition if not properly diagnosed and managed. Patients with diabetes insipidus require treatment with desmopressin or drugs increasing sensitivity of the distal nephron to vasopressin, but this treatment may be confusing because of the disorder's variable pathophysiology and side-effects of pharmacotherapy. This review summarizes the current knowledge on different aspects of the pathophysiology, classification, clinical presentation, diagnosis, and management of diabetes insipidus. The reader is also provided with some practical recommendations on dealing with patients suffering from this disease.

Diabetic dyslipidemia is characterized by elevated fasting and postprandial triglycerides, low HDL-cholesterol, elevated LDL-cholesterol and the predominance of small dense LDL particles. These lipid changes represent the major link between diabetes and the increased cardiovascular risk of diabetic patients. The underlying pathophysiology is only partially understood. Alterations of insulin sensitive pathways, increased concentrations of free fatty acids and low grade inflammation all play a role and result in an overproduction and decreased catabolism of triglyceride rich lipoproteins of intestinal and hepatic origin. The observed changes in HDL and LDL are mostly sequence to this. Lifestyle modification and glucose control may improve the lipid profile but statin therapy mediates the biggest benefit with respect to cardiovascular risk reduction. Therefore most diabetic patients should receive statin therapy. The role of other lipid lowering drugs, such as ezetimibe, fibrates, omega-3 fatty acids, niacin and bile acid sequestrants is less well defined as they are characterized by largely negative outcome trials. This review examines the pathophysiology of diabetic dyslipidemia and its relationship to cardiovascular diseases. Management approaches will also be discussed.

Disruption of water and electrolyte balance is frequently encountered in clinical medicine. Regulating water metabolism is critically important. Diabetes insipidus (DI) presented with excessive water loss from the kidney is a major disorder of water metabolism. To understand the molecular and cellular mechanisms and pathophysiology of DI and rationales of clinical management of DI is important for both research and clinical practice. This chapter will first review various forms of DI focusing on central diabetes insipidus (CDI) and nephrogenic diabetes insipidus (NDI ) . This is followed by a discussion of regulatory mechanisms underlying CDI and NDI , with a focus on the regulatory axis of vasopressin, vasopressin receptor 2 (V2R ) and the water channel molecule, aquaporin 2 (AQP2 ). The clinical manifestation, diagnosis and management of various forms of DI will also be discussed with highlights of some of the latest therapeutic strategies that are developed from in vitro experiments and animal studies.

This paper describes the importance of diabetic retinopathy in the loss of visual function. We exposed the most important risk factors, such as diabetes duration, poor metabolic control, pregnancy, puberty, hypertension, poor control of blood lipids, renal disease, and sleep apnea syndrome. We describe the pathogenesis of the disease, small retinal vessel microangiopathies which produce extravasation, edema and ischemia phenomena. We put special emphasis on the vascular endothelial growth factor (VEGF) and its pathogenic importance. They are also described the main clinical symptoms as microaneurysms, intraretinal hemorrhages, hard and soft exudates, intraretinal microvascular abnormalities (IRMA), venous disorders, formation of new vessels and diabetic macular edema (the latter being the most common cause of vision loss). Finally we describe the latest diagnostic techniques and eye treatment, with special emphasis on obesity surgery importance as more important preventive factor to eliminate the predisposing and precipitating disease symptoms.

Thalassemia is a group of disorders characterized by deficient production of the β-globin sub unit of hemoglobin. The mandatory blood transfusions in patients with thalassemia to maintain adequate erythrocyte levels, leads to iron overload. The prevalence of diabetes in patients with thalassemia varies from 6 to 14%. We here by present a known case of thalassemia major in an 18 year old boy. He was diagnosed with thalassemia before the age of one year and is on regular blood transfusion every two weeks since then. The repeated blood transfusion is one of the common causes for haemochromatosis. Iron overload initially leads to glucose abnormalities such as insulin resistance and hyperinsulinemia, which is followed by impaired secretion of insulin. Diagnosed as a case of bronze diabetes, this patient is on insulin therapy for the last two years. Currently the patient is on iron chelation therapy at Kasturba Medical College Hospital, Mangalore, Karnataka, India.

OBJECTIVE To determine the relationships among large, small, and autonomic fiber neurophysiological measures in a cross-sectional study of patients with diabetes. RESEARCH DESIGN AND METHODS We assessed 130 individuals: 25 healthy subjects and 105 subjects with diabetes. Subjects were classified by the presence or absence of neuropathy by physical examination. All subjects underwent autonomic testing, nerve conduction studies, quantitative sensory testing, and nerve-axon reflex vasodilation in addition to quantifiable neurological examination and symptom scores. Correlation and cluster analysis were used to determine relationships between and among different neurophysiological testing parameters. RESULTS Results of neurophysiological tests were abnormal in patients with clinical evidence of diabetic neuropathy compared with results in healthy control subjects and in those without neuropathy (P < 0.01, all tests). The correlations among individual tests varied widely, both within (r range <0.5–>0.9, NS to <0.001) and between test groups (r range <0.2–>0.5, NS to <0.01). A two-step hierarchical cluster analysis revealed that neurophysiological tests do not aggregate by typical “small,” “large,” or “autonomic” nerve fiber subtypes. CONCLUSIONS The modest correlation coefficients seen between the different testing modalities suggest that these techniques measure different neurophysiological parameters and are therefore not interchangeable. However, the data suggest that only a small number of neurophysiological tests are actually required to clinically differentiate individuals with neuropathy from those without. The natural clustering of both patients and healthy control subjects suggests that variations in the population will need to be considered in future studies of diabetic neuropathy. PMID:20805259

The precision medicine approach of tailoring treatment to the individual characteristics of each patient or subgroup has been a great success in monogenic diabetes subtypes, MODY and neonatal diabetes. This review examines what has led to the success of a precision medicine approach in monogenic diabetes (precision diabetes) and outlines possible implications for type 2 diabetes. For monogenic diabetes, the molecular genetics can define discrete aetiological subtypes that have profound implications on diabetes treatment and can predict future development of associated clinical features, allowing early preventative or supportive treatment. In contrast, type 2 diabetes has overlapping polygenic susceptibility and underlying aetiologies, making it difficult to define discrete clinical subtypes with a dramatic implication for treatment. The implementation of precision medicine in neonatal diabetes was simple and rapid as it was based on single clinical criteria (diagnosed <6 months of age). In contrast, in MODY it was more complex and slow because of the lack of single criteria to identify patients, but it was greatly assisted by the development of a diagnostic probability calculator and associated smartphone app. Experience in monogenic diabetes suggests that successful adoption of a precision diabetes approach in type 2 diabetes will require simple, quick, easily accessible stratification that is based on a combination of routine clinical data, rather than relying on newer technologies. Analysing existing clinical data from routine clinical practice and trials may provide early success for precision medicine in type 2 diabetes.

Diabetes is a serious disease. It means that one's blood glucose, also called blood sugar, is too high. Having too much glucose in a person's blood is not healthy. This paper offers tips for managing diabetes.
Diabetes insipidus is a heterogeneous condition characterized by polyuria and polydipsia caused by a lack of secretion of vasopressin, its physiological suppression following excessive water intake, or kidney resistance to its action. In many patients, it is caused by the destruction or degeneration of the neurons that originate in the supraoptic and paraventricular nuclei of the hypothalamus. Known causes of these lesions include: germinoma or craniopharyngioma; Langerhans cell histiocytosis and sarcoidosis of the central nervous system; local inflammatory, autoimmune or vascular diseases; trauma following surgery or accident; and, rarely, genetic defects in vasopressin biosynthesis inherited as autosomal dominant or X-linked recessive traits. Thirty to fifty percent of cases are considered idiopathic. Magnetic resonance imaging (MRI) allows identification of the posterior pituitary hyperintensity and of hypothalamic-pituitary abnormalities. Thickening of the pituitary stalk is the second most common finding on MRI scans in several local inflammatory pathologies and autoimmune diseases or germinoma, but it is not specific to any single subtype. A progressive increase in the size of the anterior pituitary gland should alert physicians to the possibility that a germinoma is present, whereas a decrease can suggest the presence of an inflammatory or autoimmune process. Most children with acquired central diabetes insipidus and a thickened pituitary stalk have anterior pituitary hormone deficiencies during follow-up. Biopsy of enlarged pituitary stalk should be reserved for patients with a hypothalamic-pituitary mass and progressive thickening of the pituitary stalk, since spontaneous recovery may occur.

The case of a 36‐year‐old male professional bodybuilder is reported. He presented to the accident and emergency department with right upper quadrant pain. This was on the background of a 15‐year history of anabolic steroid and growth hormone misuse. Examination revealed mild hepatomegaly and a random blood sugar of 30.2 mmol/l. There was no evidence of ketonuria or acidosis. Biochemical evidence of hepatitis was found, and the patient was in acute renal failure. He was given a sliding scale of insulin and an intravenous infusion of crystalloid. The hepatitis and hyperglycaemia settled with conservative treatment. It is believed that this is the first reported case of frank diabetes precipitated by supraphysiological recreational growth hormone misuse. PMID:17324962

Diabetes mellitus is a chronic metabolic disease characterized by sustained hyperglycemia leading to macro and microvascular complications. The eye is one of the main organs affected by this disease, being diabetic retinopathy the most well-known microvascular complication and the leading cause of blindness in the working age population. However, diabetic ocular disease is not only characterized by diabetic retinopathy. Other important ocular manifestations of diabetes mellitus include cataract, glaucoma, ischemic optic neuropathy, cranial nerve palsies and recurrent corneal erosion syndrome. Here, we emphasize diabetic retinopathy as the most important and characteristic complication of diabetes mellitus, but also review less well-known complications with the aim to alert and sensitize non-ophthalmologist clinicians that treat diabetic individuals, in order to promote an early diagnosis and treatment of the sight-threatening complications of diabetes.

Diabetes mellitus is the commonest cause of an autonomic neuropathy in the developed world. Diabetic autonomic neuropathy causes a constellation of symptoms and signs affecting cardiovascular, urogenital, gastrointestinal, pupillomotor, thermoregulatory, and sudomotor systems. Several discrete syndromes associated with diabetes cause autonomic dysfunction. The most prevalent of these are: generalized diabetic autonomic neuropathy, autonomic neuropathy associated with the prediabetic state, treatment-induced painful and autonomic neuropathy, and transient hypoglycemia-associated autonomic neuropathy. These autonomic manifestations of diabetes are responsible for the most troublesome and disabling features of diabetic peripheral neuropathy and result in a significant proportion of the mortality and morbidity associated with the disease.

The increasing prevalence of diabetes especially type 2 diabetes worldwide is indisputable. Diabetics suffer increased morbidity and mortality, compared to their non-diabetic counterparts, not only because of vascular complications, but also because of an increased fracture incidence. Both types 1 and 2 diabetes and some medications used to treat it are associated with osteoporotic fractures. The responsible mechanisms remain incompletely elucidated. In this review, we evaluate the role of glycemic control in bone health, and the effect of anti-diabetic medications such as thiazolidinediones, sulfonylureas, DPP-4 inhibitors, and GLP-1 agonists. In addition, we examine the possible role of insulin and metformin as anabolic agents for bone. Lastly, we identify the current and future screening tools that help evaluate bone health in diabetics and their limitations. In this way we can offer individualized treatment, to the at-risk diabetic population.

This review is a succinct description of the relationship between herpes zoster and diabetes. It makes a strong case for screening for diabetes in all patients of herpes zoster, and for using insulin to achieve optimal glycaemic control in persons with concomitant diabetes and herpes zoster. It highlights potential impact of dipeptidyl peptidase 4 inhibitor therapy and statin usage on herpes zoster incidence.

Diabetes in whites of European descent with hemochromatosis was first attributed to pancreatic siderosis. Later observations revealed that the pathogenesis of diabetes in HFE hemochromatosis is multifactorial and its clinical manifestations are heterogeneous. Increased type 2 diabetes risk in HFE hemochromatosis is associated with one or more factors, including abnormal iron homeostasis and iron overload, decreased insulin secretion, cirrhosis, diabetes in first-degree relatives, increased body mass index, insulin resistance, and metabolic syndrome. In p.C282Y homozygotes, serum ferritin, usually elevated at hemochromatosis diagnosis, largely reflects body iron stores but not diabetes risk. In persons with diabetes type 2 without hemochromatosis diagnoses, serum ferritin levels are higher than those of persons without diabetes, but most values are within the reference range. Phlebotomy therapy to achieve iron depletion does not improve diabetes control in all persons with HFE hemochromatosis. The prevalence of type 2 diabetes diagnosed today in whites of European descent with and without HFE hemochromatosis is similar. Routine iron phenotyping or HFE genotyping of patients with type 2 diabetes is not recommended. Herein, we review diabetes in HFE hemochromatosis and the role of iron in diabetes pathogenesis in whites of European descent with and without HFE hemochromatosis. PMID:28331855

The worldwide burden of diabetes and its complications in children continues to increase due to the rise in type 1 and type 2 diabetes. Although overt diabetic neuropathy is rarely present in children and adolescents with diabetes, subclinical diabetic neuropathy has been estimated to occur in approximately half of all children with type 1 diabetes with a duration of 5 years or longer and up to 25% of pediatric patients with newly diagnosed diabetes have abnormal findings on nerve conduction studies. The present review on the state of pediatric diabetic neuropathy covers the definition, prevalence, pathogenesis, diagnosis, risk factors, and possible treatment approaches specific to children and adolescents with diabetes. It also highlights the many unknowns in this field. Nonetheless, new emerging interventions that can either prevent or delay the progression of diabetic microvascular and macrovascular complications may become available in the near future. Until specific interventions for diabetic neuropathy are available for use in children, it will be hard to justify screening for neuropathy other than through clinical assessment. Meanwhile, the search for quicker, easily administered, and quantifiable tests for diabetic neuropathy and efforts to establish valid pediatric norms for well-established measures used in adults will need to continue.

There is a global diabetes epidemic correlating with an increase in obesity. This coincidence may lead to a rise in the prevalence of type 2 diabetes. There is also an as yet unexplained increase in the incidence of type 1 diabetes, which is not related to adiposity. Whilst improved diabetes care has substantially improved diabetes outcomes, the disease remains a common cause of working age adult-onset blindness. Diabetic retinopathy is the most frequently occurring complication of diabetes; it is greatly feared by many diabetes patients. There are multiple risk factors and markers for the onset and progression of diabetic retinopathy, yet residual risk remains. Screening for diabetic retinopathy is recommended to facilitate early detection and treatment. Common biomarkers of diabetic retinopathy and its risk in clinical practice today relate to the visualization of the retinal vasculature and measures of glycemia, lipids, blood pressure, body weight, smoking, and pregnancy status. Greater knowledge of novel biomarkers and mediators of diabetic retinopathy, such as those related to inflammation and angiogenesis, has contributed to the development of additional therapeutics, in particular for late-stage retinopathy, including intra-ocular corticosteroids and intravitreal vascular endothelial growth factor inhibitors ('anti-VEGFs') agents. Unfortunately, in spite of a range of treatments (including laser photocoagulation, intraocular steroids, and anti-VEGF agents, and more recently oral fenofibrate, a PPAR-alpha agonist lipid-lowering drug), many patients with diabetic retinopathy do not respond well to current therapeutics. Therefore, more effective treatments for diabetic retinopathy are necessary. New analytical techniques, in particular those related to molecular markers, are accelerating progress in diabetic retinopathy research. Given the increasing incidence and prevalence of diabetes, and the limited capacity of healthcare systems to screen and treat

Diabetes insipidus (DI) is a hereditary or acquired condition which disrupts normal life of persons with the condition; disruption is due to increased thirst and passing of large volumes of urine, even at night. A systematic search of literature for DI was carried out using the PubMed database for the purpose of this review. Central DI due to impaired secretion of arginine vasopressin (AVP) could result from traumatic brain injury, surgery, or tumors whereas nephrogenic DI due to failure of the kidney to respond to AVP is usually inherited. The earliest treatment was posterior pituitary extracts containing vasopressin and oxytocin. The synthetic analog of vasopressin, desmopressin has several benefits over vasopressin. Desmopressin was initially available as intranasal preparation, but now the oral tablet and melt formulations have gained significance, with benefits such as ease of administration and stability at room temperature. Other molecules used for treatment include chlorpropamide, carbamazepine, thiazide diuretics, indapamide, clofibrate, indomethacin, and amiloride. However, desmopressin remains the most widely used drug for the treatment of DI. This review covers the physiology of water balance, causes of DI and various treatment modalities available, with a special focus on desmopressin. PMID:26904464

Diagnosis of glomerulonephritis (GN) is rare among diabetics and few data relevant to this issue can be found in literature. In Institute of Pathology of "Szent-Györgyi Albert" University of Medicine the presence of GN was found in cases during the examination of renal biopsy material of 36 diabetics. All patients have suffered from diabetes mellitus of 2nd type and of less than 10 year existence, requiring no insulin treatment. In 2 cases diffuse diabetic glomerulosclerosis associated with GN. It is emphasized that kidney biopsy and its complex--light and electronmicroscopic and immunhistological--examination are essential to the diagnosis of GN of diabetics.

Diabetic retinopathy, a common and sight-threatening microvascular complication of diabetes mellitus, is a leading cause of blindness among working-aged adults. Medical therapies including intensive control of hyperglycemia and hypertension have been shown to reduce the incidence and progression of diabetic retinopathy. The association of dyslipidemia and treatment with statins with diabetic retinopathy is inconsistent in epidemiologic studies. However, two recent randomized clinical trials have demonstrated beneficial effects of systemic fenofibrate therapy in reducing the progression of diabetic retinopathy independently of serum lipid levels. These findings suggest that fenofibrate may be an effective strategy for reducing the progression of diabetic retinopathy, thus reducing the large and growing public health burden of treating the sight-threatening complications of diabetic retinopathy.
The diabetic foot presents a complex interplay of neuropathic, macrovascular, and microvascular disease on an abnormal metabolic background, complicated by an increased susceptibility to mechanical, thermal, and chemical injury and decreased healing ability. The abnormalities of diabetes, once present, are not curable. But most severe foot abnormalities in the diabetic are due to neglect of injury and are mostly preventable. The physician must ensure that the diabetic patient learns the principles of good foot care. If time for teaching is limited, this task must be delegated to a podiatrist or a diabetes nurse educator in a diabetes day centre. It is the physician's responsibility to confirm foot care by personal inspection of the feet of all diabetic patients at every visit. PMID:21234002

Diabetes insipidus (DI) is characterized by hypotonic polyuria greater than 3 liters/24 hours in adults and persisting even during water deprivation. It is mostly due to a defect in arginin-vasopressin (AVP) synthesis (central DI); other causes are: AVP resistance (nephrogenic DI), abnormal thirst regulation (primary polydipsia) or early destruction of AVP by placental enzymes (gestational DI). A thorough medical history is warranted to investigate nocturnal persistence of polyuria (night waking being a good sign of its organic nature) to specify the onset and duration of the trouble, the medication use and the potential hereditary nature of the disorder. The next step is based on weight and blood pressure measurements and especially the quantification of beverages and diuresis over a 24-hour cycle. Assessment of signs of dehydration, bladder distention, pituitary hormone hyper- or hyposecretion, tumor chiasmatic syndrome, granulomatosis and cancer is required. The diagnosis is based on biological assessment, pituitary magnetic resonance imaging (MRI) and results of a desmopressin test. In severe forms of DI, urine osmolality remains below 250 mOsmol/kg and serum sodium greater than 145 mmol/L. In partial forms of DI (urine osmolality between 250 and 750), the water deprivation test demonstrating the incapacity to obtain a maximal urine concentration is valuable, together with vasopressin or copeptin measurement. The pituitary MRI is done to investigate the lack of spontaneous hyperintensity signal in the posterior pituitary, which marks the absence of AVP and supports the diagnosis of central DI rather than primary polydipsia (although not absolute); it can also recognize lesions of the pituitary gland or pituitary stalk. Acquired central DI of sudden onset should suggest a craniopharyngioma or germinoma if it occurs before the age of 30 years, and metastasis after the age of 50 years. Fifteen to 20% of head trauma lead to hypopituitarism, including DI in 2% of

Diabetes education and self management has gained a critical role in diabetes care. Patient empowerment aims to actively influence the course of the disease by self-monitoring and treatment modification, as well as integration of diabetes in patients' daily life to achieve changes in lifestyle accordingly.Diabetes education has to be made accessible for all patients with the disease. To be able to provide a structured and validated education program adequate personal as well as space, organizational and financial background are required. Besides an increase in knowledge about the disease it has been shown that structured diabetes education is able to improve diabetes outcome measured by parameters like blood glucose, HbA1c, blood pressure and body weight in follow-up evaluations. Modern education programs emphasize the ability of patients to integrate diabetes in everyday life and stress physical activity besides healthy eating as a main component of lifestyle therapy and use interactive methods in order to increase the acceptance of personal responsibility.

Diabetic retinopathy and diabetic macular edema result from chronic damage to the neurovascular structures of the retina. The pathophysiology of retinal damage remains uncertain but includes metabolic and neuroinflammatory insults. These mechanisms are addressed by intensive metabolic control of the systemic disease and by the use of ocular anti-inflammatory agents, including vascular endothelial growth factor inhibitors and corticosteroids. Improved understanding of the ocular and systemic mechanisms that underlie diabetic retinopathy will lead to improved means to diagnose and treat retinopathy and better maintain vision.

In keeping with the already known high prevalence of diabetes among residents of the Jewish Home for the Aged, Toronto, annual screening disclosed an average incidence of 25.5% of abnormal glucose tolerance (two-hour post-glucose blood sugars above 140 mg./100 ml.) in residents not known to be diabetic. Forty-five (47%) of the 94 residents with abnormal screening values were considered subsequently to be diabetic according to our criteria. Long-term follow-up, particularly of 81 residents initially normoglycemic in 1964-5, confirmed that the natural course of glucose tolerance in this population was one of progressive deterioration. By contrast, improvement amounting to remission has been demonstrated in nine out of 20 residents several years after they had been declared diabetic, and is thought to have been induced by dietotherapy. Moderate hyperglycemia per se did not cause symptoms in these almost always keto-resistant and usually aglycosuric aged diabetics, who often claimed they felt better when hyperglycemic. Hypoglycemia was an ever present danger when anti-diabetic medication was used; it was the main reason for undertreatment. So far, data from our long-term study have not shown morbidity to be markedly increased in the diabetics, and mortality was found to be evenly distributed among diabetic and non-diabetic male residents. However, in the females there was a clear correlation between mortality rate and the diminished glucose tolerance. What may appear as overdiagnosis of diabetes in the aged is recommended in the hope that early institution of dietary treatment will delay the development of clinical diabetes and the need for anti-diabetic agents. This, in turn, would prevent iatrogenic hypoglycemia. It would also reduce the severity and frequency of spontaneous hypoglycemia which, we believe, occurs more commonly in the early phase of diabetes in the aged than is generally realized. PMID:5476778
Diabetes is known to increase the risk of infection and the commonest amongst them are the ones involving the genitourinary tract. The infections in a diabetic patient are unique in that they are recurrent, more severe, requiring hospitalization, and also have higher mortality than nondiabetics. Some infections are exclusively found in diabetics like the emphysematous pyelonephritis while others have their natural history complicated due to hyperglycemia. Asymptomatic bacteriuria may lead to albuminuria and urinary tract infection and may need to be treated in diabetics. Not just this certain organisms have a predilection for the genitourinary tract of the diabetic patient. All of the above makes the diabetic patient vulnerable to infections and therefore early diagnosis and appropriate treatment is mandatory. PMID:24251228

Under physiological conditions, fluid and electrolyte homoeostasis is maintained by the kidney adjusting urine volume and composition according to body needs. Diabetes Insipidus is a complex and heterogeneous clinical syndrome affecting water balance and characterized by constant diuresis, resulting in large volumes of dilute urine. With respect to the similarly named Diabetes Mellitus, a disease already known in ancient Egypt, Greece and Asia, Diabetes Insipidus has been described several thousand years later. In 1670s Thomas Willis, noted the difference in taste of urine from polyuric subjects compared with healthy individuals and started the differentiation of Diabetes Mellitus from the more rare entity of Diabetes Insipidus. In 1794, Johann Peter Frank described polyuric patients excreting nonsaccharine urine and introduced the term of Diabetes Insipidus. An hystorical milestone was the in 1913, when Farini successfully used posterior pituitary extracts to treat Diabetes Insipidus. Until 1920s the available evidence indicated Diabetes Insipidus as a disorder of the pituitary gland. In the early 1928, De Lange first observed that some patients with Diabetes Insipidus did not respond to posterior pituitary extracts and subsequently Forssman and Waring in 1945 established that the kidney had a critical role for these forms of Diabetes Insipidus resistant to this treatment. In 1947 Williams and Henry introduced the term Nephrogenic Diabetes Insipidus for the congenital syndrome characterized by polyuria and renal concentrating defect resistant to vasopressin. In 1955, du Vigneaud received the 1955 Nobel Prize in chemistry for the first synthesis of the hormone vasopressin representing a milestone for the treatment of Central Diabetes Insipidus.

Aging is associated with body composition changes that lead to glucose intolerance and increased risk of diabetes. The incidence of diabetes increases with aging, and the prevalence has increased because of the increased life expectancy of the population. Lifestyle modifications through nutrition and exercise in combination with medications are the main components of diabetes management. The potential benefits of nutrition and exercise intervention in older people with diabetes are enormous. Nutrition and exercise training are feasible even in frail older people living in care homes and should take into consideration individual circumstances, cultural factors, and ethnic preferences.

On the basis of evidence from animal and human studies, vitamin D has emerged as a potential risk modifier for type 1 and type 2 diabetes (type 1 diabetes and type 2 diabetes). Vitamin D is thought to have both direct (through activation of the vitamin D receptor) and indirect (via regulation of calcium homeostasis) effects on various mechanisms related to the pathophysiology of both types of diabetes, including pancreatic beta cell dysfunction, impaired insulin action and systemic inflammation. Observational case-control studies have shown that vitamin D supplementation in pregnancy or early childhood is associated with reduced risk of incident type 1 diabetes. There are no trials on the effect of vitamin D (ergocalciferol or cholecalciferol) on type 1 diabetes. An association between vitamin D insufficiency and incident type 2 diabetes has been reported in longitudinal observational studies, but the association is not consistent. Results from small underpowered trials and post-hoc analyses of data from larger trials designed for bone-specific outcomes show no effect of vitamin D supplementation on glycemia in healthy adults but vitamin D may retard the progression to diabetes in adults with glucose intolerance. Because vitamin D is an excellent marker of general health status, the positive results reported in some observational studies might reflect unmeasured and unaccounted confounding. Therefore, the hypothesis that vitamin D may modify diabetes risk needs to be confirmed in trials specifically designed for that purpose. PMID:20304061

Medical nutrition therapy (MNT) is a key component of diabetes management. The importance of balancing macronutrients, reducing carbohydrate load, lowering glycemic index, and implementing an overall healthy dietary pattern are emerging as better approaches for MNT in diabetes. Recent research points to improved glycemic control, reduction in body weight, and improvement in many cardiovascular risk factors when these approaches are provided by registered dietitians or health care providers. This review article discusses the current evidence about the role of sensible nutrition in diabetes management. Specific eating plans for weight reduction and for patients with type 1 diabetes are also discussed.

Diabetes is a worldwide epidemic, and associated neuropathy is its most costly and disabling complication. Given the rising prevalence of painful diabetic neuropathy, it is increasingly important that we understand the best ways to diagnose and treat this condition. Diagnostic tests in this field are evolving rapidly. These include the use of skin biopsies to measure small unmyelinated fibers, as well as even newer techniques that can measure both small unmyelinated fibers and large myelinated fibers in the same biopsy. The main treatments for painful diabetic neuropathy remain management of the underlying diabetes and drugs for the relief of pain. However, emerging evidence points to major differences between type 1 and type 2 diabetes, including the ability of glycemic control to prevent neuropathy. Enhanced glucose control is much more effective at preventing neuropathy in patients with type 1 diabetes than in those with type 2 disease [corrected]. This dichotomy emphasizes the need to study the pathophysiologic differences between the two types of diabetes, because different treatments may be needed for each condition. The impact of the metabolic syndrome on neuropathy in patients with type 2 diabetes may account for the difference between the two types of diabetes and requires further study. Finally, neuropathic pain is under-recognized and undertreated despite an ever evolving list of effective drugs. Evidence exists to support several drugs, but the optimal sequence and combination of these drugs are still to be determined.

Diabetic kidney disease (DKD), which belongs to the triad of diabetic microvascular complications, is currently the main cause of end-stage renal disease in developed countries. DKD usually simultaneously leads to a deteriorated long-term control of glucose metabolism and blood pressure, and to the development of diabetic retinopathy, neuropathy and atherosclerotic complications, which are the main causes of patients' mortality. Screening of the initial stages of DKD is to be based on the detection of increased albumin leak into the urine, microalbuminuria, and the reduction of renal function by means of estimates of glomerular filtration rate based on the serum creatinine level. The main objective of the prophylactic and treatment measures is to prevent the onset of DKD, or at least to stop its transition into an irreversible, progressive stage characterised by a permanent, often nephrotic proteinuria. The basic procedures in the prevention and treatment of DKD are maintaining the optimal metabolic control of diabetes and intensive hypertension treatment based on the inhibition of the renin-angiotensin system. Reaching the stage of progressive renal insufficiency (serum creatinine level approximately > or = 200 micromol/l) is an indication for further follow-up in the nephrology department, which will then take the necessary preparatory measures for dialysis treatment. The optimal method of kidney function replacement for patients with DKD is kidney transplantation, or combined kidney-pancreas transplantation in patients with type 1 diabetes.

With the continuing expansion in international air travel, increasing numbers of diabetic patients consult physicians for advice before going abroad. Careful planning is required taking into account climatic and medical conditions at the destination. Diabetic travelers should pack an appropriate treatment kit and contract special insurance coverage for medical evacuation. Precautions are necessary to limit the effects of motion sickness and time differences on diabetes control and especially the risk of hypoglycemia. Special attention is needed to avoid digestive problems and prevent foot injuries which can lead to serious complications in diabetic patients. Diabetic patients cannot forget their health problem during vacation and must be especially cautious when traveling. However with proper training, the risks of foreign travel can be reduced to acceptable levels.
Growing epidemiologic evidence has suggested that people with diabetes mellitus are at an increased risk for the development of dementia. However, the results for the subtypes of dementia are inconsistent. This review examines the risk of dementia in people with diabetes mellitus, and discusses the possible mechanism underpinning this association. Diabetes mellitus is associated with a 1.5- to 2.5-fold greater risk of dementia among community-dwelling elderly people. Notably, diabetes mellitus is a significant risk factor for not only vascular dementia, but also Alzheimer's disease. The mechanisms underpinning the association are unclear, but it may be multifactorial in nature, involving factors such as cardiovascular risk factors, glucose toxicity, changes in insulin metabolism and inflammation. The optimal management of these risk factors in early life may be important to prevent late-life dementia. Furthermore, novel therapeutic strategies will be needed to prevent or reduce the development of dementia in people with diabetes mellitus.

Health disparities in diabetes and its complications and co-morbidities exist globally. A recent Endocrine Society Scientific Statement described the Health Disparities in several endocrine disorders, including type 2 diabetes. In this review we summarize that statement and provide novel updates on race/ethnic differences in children and adults with type 1 diabetes, children with type 2 diabetes and in Latino subpopulations. We also review race/ethnic differences in the epidemiology of diabetes, prediabetes, and diabetes complications and mortality in the United States and globally. Finally we discuss biological, behavioral, social, environmental, and health system contributors to diabetes disparities in order to identify areas for future preventive interventions. PMID:24037313

Diabetes mellitus during pregnancy could result in severe or fatal complications to mother or the unborn product, like polyhydramnios, preeclampsia, abortion, neonatal asphyxia, macrosomia, stillbirth, and others, therefore is very important the early detection and treatment of diabetes. Gestacional Diabetes Mellitus (GDM) is the carbohydrate intolerance of variable severity first recognized during pregnancy. The screening test consist of 50 g of oral glucose and a plasma glucose measurement at one hour, regardless of the time of the last meal, and this may do in all pregnancies between 24 and 28 weeks of gestation. If plasma glucose level above 140 mg/dl results, a oral glucose tolerance test with 100 g must be done. This is the GDM diagnostic test. The risk factors for gestacional diabetes (older than 30 years of age, obesity, arterial hypertension, glucosury, previous GDM, family history of diabetes, family history of macrosomia) identify only 50% of pregnancies with gestacional diabetes, therefore, is necessary to screen all pregnancies who become pregnant, a strict control before pregnant is indispensable, with aim to slow congenital malformations probability and another complications. Gestacional diabetes prevalence in hispanic women in the U.S.A. is 12.3 percent. Diabetes mellitus prevalence in Mexico is about 2-6 percent. The goal of management of diabetes during pregnancy is the maintainance of fasting plasma glucose 105 mg/dl and 120 mg/dl two hours after meals. Treatment consist in diabetes education, diet with caloric needs calculation, exercise, and occasionally insulin. Is necessary the prenatal monitoring, the supervision of delivery or cesarean metabolic changes, and the postnatal monitoring of the mother and product.

Catalpol, isolated from the roots of Rehmanniaglutinosa, Chinese foxglove, is an iridoid glycoside with antioxidant, anti-inflammatory and anti-hyperglycemic agent. The present study was to investigate the effects of catalpol on diabetic atherosclerosis in alloxan-induced diabetic rabbits. Diabetes was induced in rabbits by a hyperlipidemic diet and intravenous injection of alloxan (100 mg/kg). Rabbits were treated for 12 weeks. The fasting blood glucose, insulin, homeostasis model of insulin resistance, total cholesterol and triglyceride were measured. The thoracic aorta was excised for histology. The plasma and vascular changes including some markers of oxidative stress, inflammatory cytokines and fibrosis factors were examined. Plasma levels of fasting blood glucose, insulin and homeostasis model of insulin resistance were significantly decreased in catalpol group. Catalpol treatment ameliorated diabetic atherosclerosis in diabetic rabbits as demonstrated by significantly inhibited neointimal hyperplasia and macrophages recruitment. Catalpol treatment also enhanced the activities of superoxide dismutase, glutathione peroxidase, and increased the plasma levels of total antioxidant status, meanwhile reduced the levels of malondialdehyde, protein carbonyl groups and advanced glycation end product. Furthermore, catalpol also reduced circulating levels of tumor necrosis factor-α, monocyte chemotactic protein-1 and vascular cell adhesion molecule-1. Catalpol also decreased transforming growth factor-β1 and collagen IV mRNA and protein expressions in the vessels. Catalpol exerts an ameliorative effect on atherosclerotic lesion in alloxan-induced diabetic rabbits. The possible mechanisms may be related to inhibition of oxidative stress inflammatory response and anti-fibrosis and reduced aggregation of extracellular matrix. PMID:27830011

This article focuses on (a) identifying obesity and other risk factors for developing type 2 diabetes, (b) differentiating between pediatric type 1 diabetes and type 2 diabetes, and (c) treating pediatric type 2 diabetes. Obesity has significant implications on a child's health, including an increased risk for insulin resistance and progression to type 2 diabetes. Type 2 diabetes in children, characterized by insulin resistance and relative pancreatic b-cell failure due to the increased demand for insulin production, has now reached epidemic proportions. Longitudinal research on pediatric type 2 diabetes, however, is lacking because this epidemic is relatively new. Treatment of type 2 diabetes in children is focused on lifestyle modification with weight management/increased physical activity, and pharmacological management through oral medication or insulin therapy. Because children with type 2 diabetes are at risk for developing diabetes-related complications earlier in life, they need to be closely monitored for comorbidities.

Synopsis There has been increasing evidence suggesting that vitamin D may play an important role in modifying risk of diabetes. In this regard, Vitamin D has both direct and indirect effects, the latter via regulation of calcium effects on various mechanisms related to the pathophysiology of type 2 diabetes, including pancreatic beta cell dysfunction, impaired insulin action and systemic inflammation. The human evidence comes primarily from many cross-sectional and prospective observational studies, most of which showed an inverse association between vitamin D status and prevalence or incidence of type 2 diabetes. The effect of vitamin D supplementation on glycemia or incident type 2 diabetes has been reported in several trials with mixed results. The present article describes the biological plausibility behind the potential association between vitamin D and type 2 diabetes and summarizes the current evidence supporting a relation between vitamin D and type 2 diabetes and briefly reports on the potential association between vitamin D and type 1 diabetes.

Preexisting type-I-diabetes (incidence 0.8%) and gestational diabetes (3-5%) are the two manifestations of disturbed carbohydrate metabolism in pregnancy. Maternal hyperglycemia and the resulting excessive glucose supply for the fetus leads to fetal hyperinsulinism which is responsible for the complications in the offspring. The most important clinical manifestations are the excessive growth of the fetus (macrosomia), the risk of intrauterine death and the neonatal morbidity caused by hypoglycemia and the delay of maturation of lungs and liver. Women with type-I-diabetes require preconception counseling and optimizing of glucose control to reduce the rate of abortion and of congenital anomalies of the offspring. Furthermore kidney function and retinopathia should be evaluated preconceptionally. The management of diabetic pregnancies requires a tight cooperation of obstetricians and diabetologists. Blood glucose levels have to be lower than outside pregnancy. Gestational diabetes is diagnosed by a screening test with 50 g glucose for all women followed by a regular 75 g oGTT when the glucose value is > or = 140 mg%. In most of the women euglycemia can be achieved by diet and exercise. Women after pregnancies with gestational diabetes should be retested postnatally and counseled about their increased risk to develop diabetes in later life.
The contributions to our present knowledge and understanding of diabetes insipidus are briefly surveyed. Though a disease presenting with polyuria and thirst had been recognized since Antiquity, it was not until the 17. Century the distinction was made between diabetes insipidus and diabetes mellitus. At the beginning of the 20. Century almost nothing was known about the function of the pituitary. It was generally believed that diabetes insipidus was a renal disease. Two clinical observations in 1912 suggested an association between the hypophysis and diabetes insipidus. This view was supported by the recognition in 1913 that extract of the posterior lobe of the pituitary was effective in diabetes insipidus. Despite much evidence to the contrary, it was assumed that the antidiuretic hormone was produced in the intermediate lobe of the pituitary. Around 1950 it was finally established that 'the posterior lobe hormones' are in fact secreted in the hypothalamus. At the same time the antidiuretic hormone was isolated and synthesized. More recently, progress within genetics has made it possible to characterize in details other rare types of diabetes insipidus.
People with type 2 diabetes are at increased risk of many complications, which are mainly due to complex and interconnected mechanisms such as hyperglycemia, insulino-resistance, low-grade inflammation and accelerated atherogenesis. Cardi-cerebrovascular disease are frequently associated to type 2 diabetes and may become life threatening, particularly coronaropathy, stroke and heart failure. Their clinical picture are sometimes atypical and silencious for a long time. Type 2 diabetes must be considered as an independent cardiovascular risk factor. Nephropathy is frequent in type 2 diabetes but has a mixed origin. Now it is the highest cause of end-stage renal disease. Better metabolic and blood pressure control and an improved management of microalbuminuria are able to slowdown the course of the disease. Retinopathy which is paradoxically slightly progressive must however be screened and treated in these rather old patients which are globally at high ophthalmologic risk. Diabetic foot is a severe complication secondary to microangiopathy, microangiopathy and neuropathy. It may be considered as a super-complication of several complications. Its screening must be done on a routine basis. Some cancer may be considered as an emerging complication of type 2 diabetes as well as cognitive decline, sleep apnea syndrome, mood disorders and bone metabolism impairments. Most of the type 2 diabetes complications may be prevented by a strategy combining a systematic screening and multi-interventional therapies.
Diabetes mellitus, particularly type 2 diabetes, is a risk factor for dementia and this holds true for incident vascular dementia and Alzheimer's disease. Cerebrovascular complications of diabetes and chronic mild inflammation in insulin resistant states partly account for this increased risk. In addition, cellular resistance to the trophic effects of insulin on neurons and glial cells favor the accumulation of toxic metabolic products, such as amyloid and hyperphosphorylated tau protein (pTau). Weight loss frequently precedes overt cognitive symptoms of Alzheimer's disease. This results in an increased risk of hypoglycemic episodes in stable diabetic patients who are on suitably adjusted doses of oral insulin or insulinotropic antidiabetic drugs. In turn, hypoglycemic episodes may induce further damage in the vulnerable brains of type 2 diabetes patients. Patients with unexplained weight loss, hypoglycemic episodes and subjective memory complaints must be screened for dementia. Once dementia has been diagnosed the goals of diabetes management must be reevaluated as prevention of hypoglycemia becomes more important than tight metabolic control. As weight loss accelerates the rate of cognitive decline, nutritional goals must aim at stabilizing body weight. There is no available evidence on whether drug treatment of diabetes in middle-aged persons can help to prevent dementia; however, physical exercise, mental activity and higher education have preventive effects on the risk of dementia in later life. In addition, nutritional recommendations that are effective in preventing cardiovascular events have also been shown to reduce the risk of dementia.
The prevalence of diabetes is increasing globally, particularly in Asia. According to the 2013 Diabetes Atlas, an estimated 366 million people are affected by diabetes worldwide; 36% of those affected live in the Western Pacific region, with a significant proportion in East Asia. The reasons for this marked increase in the prevalence of diabetes can be extrapolated from several distinct features of the Asian region. First, the two most populated countries, China and India, are located in Asia. Second, Asians have experienced extremely rapid economic growth, including rapid changes in dietary patterns, during the past decades. As a result, Asians tend to have more visceral fat within the same body mass index range compared with Westerners. In addition, increased insulin resistance relative to reduced insulin secretory function is another important feature of Asian individuals with diabetes. Young age of disease onset is also a distinctive characteristic of these patients. Moreover, changing dietary patterns, such as increased consumption of white rice and processed red meat, contributes to the deteriorated lifestyle of this region. Recent studies suggest a distinctive responsiveness to novel anti-diabetic agents in Asia; however, further research and efforts to reverse the increasing prevalence of diabetes are needed worldwide.

The concept of bioreactors in biochemical engineering is a well-established process; however, the idea of applying bioreactor technology to biomedical and tissue engineering issues is relatively novel and has been rapidly accepted as a culture model. Tissue engineers have developed and adapted various types of bioreactors in which to culture many different cell types and therapies addressing several diseases, including diabetes mellitus types 1 and 2. With a rising world of bioreactor development and an ever increasing diagnosis rate of diabetes, this review aims to highlight bioreactor history and emerging bioreactor technologies used for diabetes-related cell culture and therapies.

The bone mineral status of fifty-one children with diabetes mellitus was studied by single photon absorptiometry. The mean bone mineral content was 13% below values predicted by age, sex, height, and weight. Those children whose diabetes was one year or less in duration were as osteopenic as those whose diabetes was of longer duration. The demineralized children received a higher daily insulin dose than others. No association was noted between the degree of skeletal demineralization and sex, statural growth, renal function, and serum calcium and phosphorus. No significant changes in bone mineral content were noted longitudinally.

Type 2 diabetes mellitus is characterized by hyperglycemia, insulin resistance, and relative impairment in insulin secretion and its possible long term complications. Its pathogenesis is poorly understood, but both genetic and environmental factors, such as obesity and aging, play a key role. "Diabesity" is a new term which refers to diabetes occurring in the context of obesity. In this article, we will discuss the epidemiology and impact of diabetes and obesity and will also outline the components of the metabolic syndrome and the studies that demonstrate that screening and prevention are possible in an attempt to control this epidemic.

Multiple myeloma is a malignant plasma cell disorder that accounts for approximately 10% of all hematologic cancers. It is characterized by accumulation of clonal plasma cells, predominantly in the bone marrow. The prevalence of type 2 diabetes is increasing; therefore, it is expected that there will be an increase in the diagnosis of multiple myeloma with concomitant diabetes mellitus. The treatment of multiple myeloma and diabetes mellitus is multifaceted. The coexistence of the two conditions in a patient forms a major challenge for physicians. PMID:22363889

Diabetic nephropathy, the most common etiology for end-stage renal disease, complicates approximately 5% of insulin-dependent diabetic pregnancies. Assessment for vasculopathy is important before pregnancy because nephropathy can increase perinatal risks including potential for preeclampsia and preterm birth. Counseling women receiving renoprotective medications including angiotensin converting enzyme inhibitors has recently become complicated in light of new information suggesting a teratogenic risk for these agents. Most reproductive age women with overt diabetic nephropathy have preserved renal function and do not seem to have the progression of their disease affected by pregnancy. Perinatal outcomes are excellent for these women who have received care in tertiary institutions. However, there are relatively few women with significant renal impairment included in case series of pregnancies complicated by diabetic nephropathy. For these women, adverse perinatal outcomes are more common, and the effect of pregnancy on the course of their disease is less certain.

This study of 168 diabetic children from Tyneside and Teeside aimed to record what the children actually ate and to compare this with both their prescribed diet and current recommendations. The amounts of energy consumed were similar to those expected of non-diabetic children, but the components of the diabetic children's diets were different, consisting of more fat and fibre, but less sugars and carbohydrates. They ate more carbohydrate than prescribed but less than current recommendations as there was a shortfall between the amount prescribed and that suggested in the recommendations. Diabetic control was related to the amount of fibre consumed and to compliance with the prescribed diet, but not to the proportion of energy taken as carbohydrate. The insulin dose was slightly lower in those children eating more fibre. PMID:3006604

The first diabetes technology meeting organized by the European Diabetes Association covers the range from regulatory aspects, patient safety, about registries to clinical studies. After an intensive discussion about the evidence required for registration and reimbursement on new medical devices and in vitro diagnostics it becomes clear that more and better clinical trials will be required in the future. This was also highlighted by representatives of the American Diabetes Association. The 2 associations will be active in this field of research by a joint committee. This meeting is intended not to become a large-scale meeting focused on education but to provide a platform for an open discussion of experts involved in all areas that are relevant to achieve a meaningful usage of diabetes technology.

Peripheral neuropathy is common complication of diabetes. The prevalence of peripheral neuropathy among diabetic patients on the basis of loss of vibration sensation had been studied. Detailed clinical history of each patient including age, gender, duration of diabetes, foot ulcer and biothesiometry was recorded in 211 diabetic patients between 20 and 80 years of age. It was observed that all patients under 30 years age (n = 8) felt vibration below 15 volts (no risk zone); 77% (24 out of 31) of the patients in the age group of 30-39 years were in the no risk zone, and 23% (n = 7) had mild peripheral neuropathy. Sixty per cent of the patients between 40 and 50 years (n = 44) were in the no risk zone, while 32% (n = 24) had mild peripheral neuropathy, 5% (n = 4) had moderate neuropathy and 3% (n = 2) had severe peripheral neuropathy. Amongst patients above 50 years of age, 31% (n = 31) were in no risk zone, 34% (n = 34) had mild peripheral neuropathy, 22% (n = 20) had moderate peripheral neuropathy and 13% (n = 13) had severe peripheral neuropathy. Of the patients with diabetes for less than 5 years, 58% had no neuropathy, and only 3% had severe neuropathy. Of the patients with diabetes for 5 to 15 years, 50% had no neuropathy, 30% had mild, and 10% had severe peripheral neuropathy. When patients with diabetes for over 15 years were studied, only 6% had no neuropathy and 19% had severe peripheral neuropathy. The study re-establishes that the severity of peripheral neuropathy increases with age and vibration perception decreses progressively with increased duration of diabetes. Vibration perception threshold testing helps to identify the high risk subjects who require special counselling and education to protect their feet.

Research suggests a possible link between type 2 diabetes and several malignancies. Animal models have shown that hyperinsulinemic state underlying diabetes promotes tumor formation through stimulation of insulin-IGF-1 pathway; a possible role of inflammation is also proposed. One such link which has been under considerable study for years is that between diabetes and pancreatic cancer. Although epidemiological evidence points towards a reciprocal link between the two, the cause-effect relationship still remains unclear. This link was the subject of a large German epidemiological study presented at the American Society of Clinical Oncology Annual Meeting 2014 (Abstract #1604), which underscored the link between diabetes and some cancers. Schmidt et al. performed a retrospective database analysis over a 12 year period and reported an increased risk of certain types of cancer in diabetic patients. The most significant association (HR 2.17) was found for pancreatic cancer. Given the high mortality of pancreatic cancer, prevention through timely screening could play an important role in improving prognosis. Older subjects with recent-onset diabetes represent a high-risk group and hence are potential targets for pancreatic cancer screening thereby enabling its early diagnosis at a curable stage.
Bichet, Daniel Georges
Nephrogenic diabetes insipidus which can be inherited or acquired, is characterized by an inability to concentrate urine despite normal or elevated plasma concentrations of the antidiuretic hormone, arginine-vasopressine (AVP). Polyuria, with hyposthenuria and polydipsia are the cardinal clinical manifestations of the disease. Hypercalcemia, hypokaliemia, lithium administration and chronic renal failure are the principal causes of acquired nephrogenic diabetes insipidus. About 90 percent of patients with congenital nephrogenic diabetes insipidus are males with X-linked recessive nephrogenic diabetes insipidus who have mutations in the arginine-vasopressin receptor 2 (AVPR2) gene that codes for the vasopressin V2 receptor. The gene is located in chromosome region Xq28. In about 10 percent of the families studied, congenital nephrogenic diabetes insipidus has an autosomal recessive or autosomal dominant mode of inheritance. In these cases, mutations have been identified in the aquaporin-2 gene (AQP2), which is located in chromosome region 12q13 and codes for the vasopressin-sensitive water channel. Other inherited disorders with mild, moderate or severe inability to concentrate urine include Bartter's syndrome and Cystinosis. Identification of the molecular defect underlying congenital nephrogenic diabetes insipidus is of immediate clinical significance because early diagnosis and treatment of affected infants can avert the physical and mental retardation associated with episodes of dehydration.

Diabetes is a chronic illness that has an effect on multiple organ systems. Frailty is a state of increased vulnerability to stressors and a limited capacity to maintain homeostasis. It is a multidimensional concept and a dynamic condition that can improve or worsen over time. Frailty is either physical or psychological or a combination of these two components. Sarcopenia, which is the age-related loss of skeletal muscle mass and strength, is the main attributor to the physical form of frailty. Although the pathophysiology of diabetes is commonly focused on impaired insulin secretion, overload of gluconeogenesis and insulin resistance, newer insights broaden this etiologic horizon. Immunologic factors that create a chronic state of low-grade inflammation--'inflammaging'--have an influence on both the ageing process and diabetes. Persons with diabetes mellitus already tend to have an accelerated ageing process that places them at greater risk for developing frailty at an earlier age. The development of frailty--and sarcopenia--is multifactorial and includes nutritional, physical and hormonal elements; these elements are interlinked with those of diabetes. A lower muscle mass will lead to poorer glycaemic control through lower muscle glucose uptake. This leads to higher insulin secretion and insulin resistance, which is the stepping stone for diabetes itself.

Corneal epithelial lesions can be found in approximately one-half of asymptomatic patients with diabetes mellitus. These lesions are transient and clinically resemble the keratopathy seen in staphylococcal keratoconjunctivitis. Staphylococcal organisms, however, can be isolated in equal percentages from diabetic patients without keratopathy. Diabetic peripheral neuropathy was found to be related to the presence of diabetic keratopathy after adjusting for age with analysis of covariance. The strongest predictor of both keratopathy and corneal fluorescein staining was vibration perception threshold in the toes (P less than 0.01); and the severity of keratopathy was directly related to the degree of diminution of peripheral sensation. Other predictors of keratopathy were: reduced tear breakup time (P less than 0.03), type of diabetes (P less than 0.01), and metabolic status as indicated by c-peptide fasting (P less than 0.01). No significant relationships were found between the presence of keratopathy and tear glucose levels, endothelial cell densities, corneal thickness measurements, the presence of S epidermidis, or with duration of disease. It is our conclusion that asymptomatic epithelial lesions in the nontraumatized diabetic cornea can occur as a manifestation of generalized polyneuropathy and probably represent a specific form of corneal neuropathy.

We recently investigated two patients with diabetes and elevated serum prolactin levels in whom no cause of hyperprolactinaemia could be found. For this reason we measured fasting serum prolactin levels in 72 diabetic males and compared the results with those of 63 healthy males and 90 nondiabetic males attending an Impotence Clinic. The diabetic group had significantly higher serum prolactin levels (13.1 +/- 0.9 ng/ml) than the two control groups (9.9 +/- 0.6 ng/ml for normal males and 7.7 +/- 0.3 ng/ml for the non-diabetic impotent group). Eighteen percent of the diabetics studied had serum prolactin levels above the normal range for males (greater than 20 ng/ml). There was no correlation between serum prolactin levels and duration of diabetes, glycosylated haemoglobin level or presence of clinically apparent retinopathy. The correlation between serum prolactin level and fasting plasma glucose was weak though statistically significant (r = 0.26, P less than 0.05). PMID:3991396

Zinc (Zn) is an important nutrient that is involved in various physiological metabolisms. Zn dyshomeostasis is often associated with various pathogeneses of chronic diseases, such as metabolic syndrome, diabetes, and related complications. Zn is present in ocular tissue in high concentrations, particularly in the retina and choroid. Zn deficiencies have been shown to affect ocular development, cataracts, age-related macular degeneration, and even diabetic retinopathy. However, the mechanism by which Zn deficiency increases the prevalence of diabetic retinopathy remains unclear. In addition, due to the negative effect of Zn deficiency on the eye, Zn supplementation should prevent diabetic retinopathy; however, limited available data do not always support this notion. Therefore, the goal of this paper was to summarize these pieces of available information regarding Zn prevention of diabetic retinopathy. Current theories and possible mechanisms underlying the role of Zn in the eye-related diseases are discussed. The possible factors that affect the preventive effect of Zn supplementation on diabetic retinopathy were also discussed. PMID:23671870

There is a groving number of women with pregestational diabetes mellitus. Additionaly, nowadays therapy of diabetes mellitus type I allows gravidity even in patients in whom diabetes manifested itself during their early childhood. Presence of chronic complications of diabetes increases risk of complications during pregnancy. There is incerasing number of patients with DM type II and appearence of it shifts into younger age group. Perinatal mortality and morbidity of children of mothers with pregestional diabets is higher than in comparison with common population and pregnancy planning is important measure to their decrease.Key words: pregnancy - diabetes mellitus - embryopathy - fetopathy.

There is strong evidence that diabetes mellitus increases the risk of cognitive impairment and dementia. Insulin signaling dysregulation and small vessel disease in the base of diabetes may be important contributing factors in Alzheimer’s disease and vascular dementia pathogenesis, respectively. Optimal glycemic control in type 1 diabetes and identification of diabetic risk factors and prophylactic approach in type 2 diabetes are very important in the prevention of cognitive complications. In addition, hypoglycemic attacks in children and elderly should be avoided. Anti-diabetic medications especially Insulin may have a role in the management of cognitive dysfunction and dementia but further investigation is needed to validate these findings. PMID:27660698

A large literature has developed around methylglyoxal (MG) concerning its role in diabetes mellitus (DM) and in the development of diabetic complications. This is related to the observation that levels of reactive aldehydes, especially 2-oxoaldehydes such as MG, are elevated in DM. There are numerous metabolic origins of MG that are accentuated in DM. MG has effects on insulin secretion from pancreatic beta-cells and is a major precursor of advanced glycation endproducts (AGE). Consequently, MG has a role in primary DM as well in the etiology of long-term complications. There is an extensive literature concerning the enzymes involved in the metabolism of MG, especially the glyoxalase system and aldose reductase. In addition, there is a rapidly developing literature on the direct and indirect effects of MG on signaling pathways that impact DM. This review attempts to integrate this DM-associated literature related to MG.

Rheumatological manifestations of Diabetes Mellitus may be classified in: non articular, articular and bone conditions. Among non articular conditions, diabetic cheiroarthropathy, frequent in type I diabetes, the most important disorder related to limited joint mobility, results in stiff skin and joint contractures. Adhesive capsulitis of the shoulder, flexor tenosynovitis, and Duputryen's and Peyronie's diseases are also linked to limited joint mobility. Diffuse skeletal hyperostosis, due to calcification at entheses, is frequent and early, particularly in type 2 diabetes. Neuropathies cause some non articular conditions, mainly neuropathic arthritis, a destructive bone and joint condition more common in type I diabetes. Algodistrophy, shoulder-hand and entrapment syndromes are also frequent. Mononeuropathy causes diabetic amyotrophy, characterised by painless muscle weakness. Among muscle conditions, diabetic muscle infarction is a rare, sometimes severe, condition. Among articular conditions, osteoarthritis is frequent and early in diabetes, in which also chondrocalcinosis and gout occur. Rheumatoid arthritis (RA) and diabetes I have a common genetic background and the presence of diabetes gives to RA an unfavourable prognosis. Among bone conditions, osteopenia and osteoporosis may occur early in type 1 diabetes. Contrarily, in type 2 diabetes, bone mineral density is similar or, sometimes, higher than in non diabetic subjects, probably due to hyperinsulinemia.

We aimed to summarize the etiology, clinical characteristics, diagnosis, and possible treatment options of sexual dysfunction in diabetic patients of both sexes. Details of dysfunction in diabetic women are less conclusive than in men due to the lack of standardized evaluation of sexual function in women. Male sexual dysfunction is a common complication of diabetes, including abnormalities of orgasmic/ejaculatory function and desire/libido in addition to penile erection. The prevalence of erectile dysfunction (ED) among diabetic men varies from 35% to 75%. Diabetes-induced ED has a multifactorial etiology including metabolic, neurologic, vascular, hormonal, and psychological components. ED should be regarded as the first sign of cardiovascular disease because it can be present before development of symptomatic coronary artery disease, as larger coronary vessels better tolerate the same amount of plaque compared to smaller penile arteries. The diagnosis of ED is based on validated questionnaires and determination of functional and organic abnormalities. First-, second- and third-line therapy may be applied. Phosphodiesterase-5 (PDE-5) inhibitor treatment from the first-line options leads to smooth muscle relaxation in the corpus cavernosum and enhancement in blood flow, resulting in erection during sexual stimulus. The use of PDE-5 inhibitors in the presence of oral nitrates is strictly contraindicated in diabetic men, as in nondiabetic subjects. All PDE-5 inhibitors have been evaluated for ED in diabetic patients with convincing efficacy data. Second-line therapy includes intracavernosal, trans- or intraurethral administration of vasoactive drugs or application of a vacuum device. Third-line therapies are the implantation of penile prosthesis and penile revascularization.

Hyperlipidemia is common in diabetic patients. While our understanding of lipid and lipoprotein metabolism in diabetes is incomplete, a pathophysiologic approach to this problem is presented. It is based on the recognition that diabetes is metabolically heterogeneous. Thus the roles of insulin deficiency, insulin resistance, obesity, and genetic factors are discussed in relation to their effects on lipoprotein production and catabolism. The most important defect in insulin-deficient subjects appears to be a deficiency of lipoprotein lipase, which is responsible for the removal of the triglyceride-rich lipoproteins. In non-insulin-dependent subjects there is evidence for a removal defect as well as, in some patients, for overproduction of VLDL-triglyceride. Cholesterol levels may be elevated and it is important to distinguish between VLDL, LDL, and HDL as the causes for these increases. HDL-cholesterol levels may be increased in insulin-dependent subjects, whereas they may be decreased in obese non-insulin-dependent patients. Mild elevations of LDL-cholesterol may occur in inadequately controlled type I and II diabetic patients, while elevated VLDL may raise the serum cholesterol in addition to the triglyceride levels. The rationale for therapy is based on the complications of severe hypertriglyceridemia and the risk of occlusive atherosclerosis. Management is directed at improving glycemic control, altering dietary composition, and reducing calories in obese patients. Improved glycemic control is effective in reducing triglyceride and cholesterol levels in insulin-deficient subjects. The response of the non-insulin-dependent diabetic patient to improved control may be complicated by associated obesity or familial hyperlipidemia. The advantages and disadvantages of fat versus carbohydrate restriction in the diet are discussed. Finally, resistant hyperlipidemia may require drug therapy. Diabetic hyperlipidemia should be viewed as resulting from an interaction between

Introduction Up to one third of people with type 1 or 2 diabetes will develop microalbuminuria or macroalbuminuria after 20 years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in people with type 1 diabetes and early nephropathy? What are the effects of treatments in people with type 1 diabetes and late nephropathy? What are the effects of treatments in people with type 2 diabetes and early nephropathy? What are the effects of treatments in people with type 2 diabetes and late nephropathy? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers, glycaemic control, protein restriction, and tight control of blood pressure.

Exercise is frequently recommended in the management of type 1 and 2 diabetes mellitus and can improve glucose uptake by increasing insulin sensitivity and lowering body adiposity. Both alone and when combined with diet and drug therapy, physical activity can result in improvements in glycaemic control in type 2 diabetes. In addition, exercise can also help to prevent the onset of type 2 diabetes, in particular in those at higher risk, and has an important role in reducing the significant worldwide burden of this type of diabetes. Recent studies have improved our understanding of the acute and long term physiological benefits of physical activity, although the precise duration, intensity, and type of exercise have yet to be fully elucidated. However, in type 1 diabetes, the expected improvements in glycaemic control with exercise have not been clearly established. Instead significant physical and psychological benefits of exercise can be achieved while careful education, screening, and planning allow the metabolic, microvascular, and macrovascular risks to be predicted and diminished.

Free clinics across the country provide free or reduced fee healthcare to individuals who lack access to primary care and are socio-economically disadvantaged. This study examined perceived health status among diabetic and non-diabetic free clinic patients and family members of the patients. Diabetes self-efficacy among diabetic free clinic patients was also investigated with the goal of developing appropriate diabetes health education programs to promote diabetes self-management. English or Spanish speaking patients and family members (N = 365) aged 18 years or older completed a self-administered survey. Physical and mental health and diabetes self-efficacy were measured using standardized instruments. Diabetic free clinic patients reported poorer physical and mental health and higher levels of dysfunction compared to non-diabetic free clinic patients and family members. Having a family history of diabetes and using emergency room or urgent care services were significant factors that affected health and dysfunction among diabetic and non-diabetes free clinic patients and family members. Diabetic free clinic patients need to receive services not only for diabetes, but also for overall health and dysfunction issues. Diabetes educational programs for free clinic patients should include a component to increase diabetes empowerment as well as the knowledge of treatment and management of diabetes. Non-diabetic patients and family members who have a family history of diabetes should also participate in diabetes education. Family members of free clinic patients need help to support a diabetic family member or with diabetes prevention.

Any adult with diabetes in the tropics with hand cellulitis, infection and gangrene qualifies for tropical diabetic hand syndrome (TDHS). We reviewed a 39-year-old woman with a 3-week history of swelling of the left index finger following an insect bite. The swelling progressively increased in size, was very painful, and extended to the palm. There was no history or symptoms suggestive of chronic complications of diabetes. Random blood sugar on presentation was above 600 mg/dl using a glucometer. Examination revealed an edematous left palm draining pus from multiple sinuses, necrotic and gangrenous left index finger extending down to just above the thenar eminence. A diagnosis of TDHS in a patient with hyperosmolar state was made. She was managed accordingly and subsequently underwent aggressive debridement and desloughing. Two fingers were amputated and the wound was allowed to heal by secondary intention. PMID:27057390
Studies of patients going into diabetes remission after gastric bypass surgery have demonstrated the important role of the gut in glucose control. The improvement of type 2 diabetes after gastric bypass surgery occurs via weight dependent and weight independent mechanisms. The rapid improvement of glucose levels within days after the surgery, in relation to change of meal pattern, rapid nutrient transit, enhanced incretin release and improved incretin effect on insulin secretion, suggest mechanisms independent of weight loss. Alternatively, insulin sensitivity improves over time as a function of weight loss. The role of bile acids and microbiome in the metabolic improvement after bariatric surgery remains to be determined. While most patients after bariatric surgery experienced sustained weight loss and improved metabolism, small scale studies have shown weight regain and diabetes relapse, the mechanisms of which remain unknown. PMID:22386248
Exercise has a beneficial effect on metabolic parameters affecting cardiovascular risk, such as lipids and blood glucose, and is a key component in both the prevention and the management of type 2 diabetes. Glycaemic control improves with both aerobic and resistance exercise in type 2 diabetes, but no glycaemic benefit is seen in type 1 diabetes. This probably results from glucose fluctuations commonly seen with exercise. Low and moderate intensity exercise are generally associated with a fall in blood glucose, and high intensity exercise can be associated with a rise in blood glucose. Trial evidence is suggestive of a reduction in cardiovascular risk with exercise, although evidence from prospective, randomised controlled trials is certainly not conclusive.

The prevalence of overt diabetes mellitus (DM) in liver cirrhosis is about 30%. However, DM or impaired glucose tolerance can be observed in 90% after an oral glucose tolerance test in patients with normal fasting plasma glucose. Type 2 DM may produce cirrhosis, whereas DM may be a complication of cirrhosis. The latter is known as «hepatogenous diabetes». Overt and subclinical DM is associated with liver complications and death in cirrhotic patients. Treating diabetes is difficult in cirrhotic patients because of the metabolic impairments due to liver disease and because the most appropriate pharmacologic treatment has not been defined. It is also unknown if glycemic control with hypoglycemic agents has any impact on the course of the liver disease.

Diabetes causes a number of metabolic and physiologic abnormalities in the retina, but which of these abnormalities contribute to recognized features of diabetic retinopathy (DR) is less clear. Many of the molecular and physiologic abnormalities that have been found to develop in the retina in diabetes are consistent with inflammation. Moreover, a number of anti-inflammatory therapies have been found to significantly inhibit development of different aspects of DR in animal models. Herein, we review the inflammatory mediators and their relationship to early and late DR, and discuss the potential of anti-inflammatory approaches to inhibit development of different stages of the retinopathy. We focus primarily on information derived from in vivo studies, supplementing with information from in vitro studies were important. PMID:21635964

Methylglyoxal (MG) is a highly reactive compound derived mainly from glucose and fructose metabolism. This metabolite has been implicated in diabetic complications as it is a strong AGE precursor. Furthermore, recent studies suggested a role for MG in insulin resistance and beta-cell dysfunction. Although several drugs have been developed in the recent years to scavenge MG and inhibit AGE formation, we are still far from having an effective strategy to prevent MG-induced mechanisms. This review summarizes the mechanisms of MG formation, detoxification, and action. Furthermore, we review the current knowledge about its implication on the pathophysiology and complications of obesity and diabetes.

Recent increases in the incidence of both type 1 (T1D) and type 2 diabetes (T2D) in children and adolescents point to the importance of environmental factors in the development of these diseases. Metabolomic analysis explores the integrated response of the organism to environmental changes. Metabolic profiling can identify biomarkers that are predictive of disease incidence and development, potentially providing insight into disease pathogenesis. This review provides an overview of the role of metabolomic analysis in diabetes research and summarizes recent research relating to the development of T1D and T2D in children. PMID:26420304

Diabetic patients are concerned with foot complications when a peripheral neuropathy is present. Screening of predisposed patients may be annually assessed using monofilament testing. Peripheral arterial disease, when associated, increases amputation risk. Ideal treatment requires a multidisciplinary approach with a first-line medical treatment including an optimal off-loading of the diabetic ulcer, ulcer dertersion, glycemic control, and if necessary antibiotic therapy. In case of associated osteomyelitis, a limited surgical resection of the infected bone may be performed. In case of associated arterial disease, a revascularization procedure precede bone resection.

Gestational diabetes (GDM) is defined as any degree of glucose intolerance with onset during pregnancy and is associated with increased feto-maternal morbidity as well as long-term complications in mothers and offspring. Women detected to have diabetes early in pregnancy receive the diagnosis of overt, non-gestational, diabetes. GDM is diagnosed by an oral glucose tolerance test (OGTT) or fasting glucose concentrations (> 92 mg/dl). Screening for undiagnosed type 2 diabetes at the first prenatal visit (Evidence level B) is recommended in women at increased risk using standard diagnostic criteria (high risk: history of GDM or pre-diabetes (impaired fasting glucose or impaired glucose tolerance); malformation, stillbirth, successive abortions or birthweight > 4,500 g in previous pregnancies; obesity, metabolic syndrome, age > 45 years, vascular disease; clinical symptoms of diabetes (e.g. glucosuria). Performance of the OGTT (120 min; 75 g glucose) may already be indicated in the first trimester in some women but is mandatory between 24 and 28 gestational weeks in all pregnant women with previous non-pathological glucose metabolism (Evidence level B). Based on the results of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study GDM is defined, if fasting venous plasma glucose exceeds 92 mg/dl or 1 h 180 mg/dl or 2 h 153 mg/dl after glucose loading (OGTT; international consensus criteria). In case of one pathological value a strict metabolic control is mandatory. All women should receive nutritional counseling and be instructed in blood glucose self-monitoring. If blood glucose levels cannot be maintained in the normal range (fasting < 95 mg/dl and 1 h after meals < 140 mg/dl) insulin therapy should be initiated. Maternal and fetal monitoring is required in order to minimize maternal and fetal/neonatal morbidity and perinatal mortality. After delivery all women with GDM have to be reevaluated as to their glucose tolerance by a 75 g OGTT (WHO criteria) 6

Diabetes mellitus has been linked to disorders of bones and joints, including neuroarthropathy, limited joint mobility, and hyperostosis. Some of the relations have known pathogenic mechanisms, but most are based on epidemiologic findings. This article reviews the associations between diabetes mellitus and its putative rheumatologic manifestations, and proposes a classification composed of four categories: consequences of diabetic complications, consequences of metabolic derangements inherent to diabetes, syndromes that may share etiologic mechanisms with microvascular disease, and probable associations. This approach may facilitate a clearer understanding of the musculoskeletal conditions that are prevalent in patients with diabetes mellitus.

A sample of 54 patients with diabetes mellitus were subjects to detailed assessment of periodontal disease levels using standard indices. In order to determine whether the severity of periodontal disease was related to the severity of diabets mellitus, a series of parameters of the diabetes mellitus population was simultaneously studied. There were no significant relationships between the levels of periodontal disease and the duration of diabetes, the type of treatment and the frequency of systemic complications. Periodontal disease in the diabetic appeared to the affected by the same etiologic factors [plaque, calculus, neglect] as would be expected in nondiabetic patients. Further studies with larger population samples would be appropriate.

Diabetes is the leading cause of peripheral neuropathy globally. Duration of diabetes, glycemic control, and preexisting cardiovascular risk factors independently correlate with the development and progression of diabetic peripheral neuropathy as well as cardiovascular autonomic neuropathy. The pathogenesis of diabetic neuropathy remains unclear, although insulin resistance, oxidative stress, mitochondrial dysfunction, abnormal glucose metabolism, advanced glycation end products, neurotrophic factors, and protein kinase C activation all may play a role. Strict glycemic control remains the only available treatment option, although other treatments are in development. Multiple options are available for symptom management. In this article, we review factors associated with development and progression of diabetic neuropathy and discuss available treatment options.

Monogenic diabetes represents a heterogeneous group of disorders resulting from defects in single genes. Defects are categorized primarily into two groups: disruption of β-cell function or a reduction in the number of β-cells. A complex network of transcription factors control pancreas formation, and a dysfunction of regulators high in the hierarchy leads to pancreatic agenesis. Dysfunction among factors further downstream might cause organ hypoplasia, absence of islets of Langerhans or a reduction in the number of β-cells. Many transcription factors have pleiotropic effects, explaining the association of diabetes with other congenital malformations, including cerebellar agenesis and pituitary agenesis. Monogenic diabetes variants are classified conventionally according to age of onset, with neonatal diabetes occurring before the age of 6 months and maturity onset diabetes of the young (MODY) manifesting before the age of 25 years. Recently, certain familial genetic defects were shown to manifest as neonatal diabetes, MODY or even adult onset diabetes. Patients with neonatal diabetes require a thorough genetic work-up in any case, and because extensive phenotypic overlap exists between monogenic, type 2, and type 1 diabetes, genetic analysis will also help improve diagnosis in these cases. Next generation sequencing will facilitate rapid screening, leading to the discovery of digenic and oligogenic diabetes variants, and helping to improve our understanding of the genetics underlying other types of diabetes. An accurate diagnosis remains important, because it might lead to a change in the treatment of affected subjects and influence long-term complications.

Neuropathy is the most common and debilitating complication of diabetes and results in pain, decreased motility, and amputation. Diabetic neuropathy encompasses a variety of forms whose impact ranges from discomfort to death. Hyperglycemia induces oxidative stress in diabetic neurons and results in activation of multiple biochemical pathways. These activated pathways are a major source of damage and are potential therapeutic targets in diabetic neuropathy. Though therapies are available to alleviate the symptoms of diabetic neuropathy, few options are available to eliminate the root causes. The immense physical, psychological, and economic cost of diabetic neuropathy underscores the need for causally targeted therapies. This review covers the pathology, epidemiology, biochemical pathways, and prevention of diabetic neuropathy, as well as discusses current symptomatic and causal therapies and novel approaches to identify therapeutic targets.

Diabetes has become one of the largest global health-care problems of the 21 (st) century. According to the Centers for Disease Control and Prevention, the population prevalence of diabetes in the US is approaching 10% and is increasing by 5% each year. Diabetic neuropathy is the most common complication associated with diabetes mellitus. Diabetes causes a broad spectrum of neuropathic complications, including acute and chronic forms affecting each level of the peripheral nerve, from the root to the distal axon. This review will focus on the most common form, distal symmetric diabetic polyneuropathy. There has been an evolution in our understanding of the pathophysiology and the management of diabetic polyneuropathy over the past decade. We highlight these new perspectives and provide updates from the past decade of research.

Diabetes mellitus (DM) frequency is a growing problem worldwide, because of long life expectancy and life style modifications. In old age (≥60–65 years old), DM is becoming an alarming public health problem in developed and even in developing countries as for some authors one from two old persons are diabetic or prediabetic and for others 8 from 10 old persons have some dysglycemia. DM complications and co-morbidities are more frequent in old diabetics compared to their young counterparts. The most frequent are cardiovascular diseases due to old age and to precocious atherosclerosis specific to DM and the most bothersome are visual and cognitive impairments, especially Alzheimer disease and other kind of dementia. Alzheimer disease seems to share the same risk factors as DM, which means insulin resistance due to lack of physical activity and eating disorders. Visual and physical handicaps, depression, and memory troubles are a barrier to care for DM treatment. For this, old diabetics are now classified into two main categories as fit and independent old people able to take any available medication, exactly as their young or middle age counterparts, and fragile or frail persons for whom physical activity, healthy diet, and medical treatment should be individualized according to the presence or lack of cognitive impairment and other co-morbidities. In the last category, the fundamental rule is “go slowly and individualize” to avoid interaction with poly medicated elder persons and fatal iatrogenic hypoglycemias in those treated with sulfonylureas or insulin.

Type 2 diabetes mellitus (T2DM) is increasingly common worldwide. Related complications account for increased morbidity and mortality, and enormous healthcare spending. Knowledge of the pathophysiological derangements involved in the occurrence of diabetes and related complications is critical for successful prevention and control solutions. Epidemiologic studies have established an association between inflammatory biomarkers and the occurrence of T2DM and complications. Adipose tissue appears to be a major site of production of those inflammatory biomarkers, as a result of the cross-talk between adipose cells, macrophages, and other immune cells that infiltrate the expanding adipose tissue. The triggering mechanisms of the inflammation in T2DM are still ill-understood. Inflammatory response likely contributes to T2DM occurrence by causing insulin resistance, and is in turn intensified in the presence of hyperglycemia to promote long-term complications of diabetes. Targeting inflammatory pathways could possibly be a component of the strategies to prevent and control diabetes and related complications.

With a global prevalence of 9%, diabetes is the direct cause of millions of deaths each year and is quickly becoming a health crisis. Major long-term complications of diabetes arise from persistent oxidative stress and dysfunction in multiple metabolic pathways. The most serious complications involve vascular damage and include cardiovascular disease as well as microvascular disorders such as nephropathy, neuropathy, and retinopathy. Current clinical analyses like glycated hemoglobin and plasma glucose measurements hold some value as prognostic indicators of the severity of complications, but investigations into the underlying pathophysiology are still lacking. Advancements in biotechnology hold the key to uncovering new pathways and establishing therapeutic targets. Metabolomics, the study of small endogenous molecules, is a powerful toolset for studying pathophysiological processes and has been used to elucidate metabolic signatures of diabetes in various biological systems. Current challenges in the field involve correlating these biomarkers to specific complications to provide a better prediction of future risk and disease progression. This review will highlight the progress that has been made in the field of metabolomics including technological advancements, the identification of potential biomarkers, and metabolic pathways relevant to macro- and microvascular diabetic complications.

Diabetes is considered to be a genetically and environmentally based chronic metabolic and vascular syndrome caused by a partial or total insulin deficiency with alteration in the metabolism of lipids, carbohydrates and proteins culminating with different manifestations in different organisms. In humans hyperglycemia is the main consequence of defects in the secretion and/or action of insulin, and its deregulation can produce secondary lesions in various organs, especially kidneys, eyes, nerves, blood vessels and immune systems. Periodontal disease is an entity of localized infection that involves tooth-supporting tissues. The first clinical manifestation of periodontal disease is the appearance of periodontal pockets, which offer a favorable niche for bacterial colonization. The etiology of periodontal disease is multifactorial, being caused by interactions between multiple micro-organisms (necessary but not sufficient primary etiologic factors), a host with some degree of susceptibility and environmental factors. According to current scientific evidence, there is a symbiotic relationship between diabetes and periodontitis, such that diabetes is associated with an increased incidence and progression of periodontitis, and periodontal infection is associated with poor glycaemic control in diabetes due to poor immune systems. Hence, for a good periodontal control it is necessary to treat both periodontal disease and glycaemic control.

Improved life expectancy in cystic fibrosis (CF) has led to an expanding population of adults with CF, now representing almost 50 % of the total CF population. This creates new challenges from long-term complications such as diabetes mellitus (DM), a condition that is present in 40 %-50 % of adults with CF. Cystic fibrosis-related diabetes (CFRD) results from a primary defect of insulin deficiency and although sharing features with type 1 (DM1) and type 2 diabetes (DM2), it is a clinically distinct condition. Progression to diabetes is associated with poorer CF clinical outcomes and increased mortality. CFRD is not associated with an increased risk of cardiovascular disease and the prevalence of microvascular complications is lower than DM1 or DM2. Rather, the primary goal of insulin therapy is the preservation of lung function and optimization of nutritional status. There is increasing evidence that appropriate screening and early intervention with insulin can reverse weight loss and improve pulmonary function. This approach may include targeting postprandial hyperglycemia not detected by standard diagnostic tests such as the oral glucose tolerance test. Further clinical research is required to guide when and how much to intervene in patients who are already dealing with the burden of one chronic illness.

New literature data and the results of own researches concerning the role of excessive body weight and the development of type 2 diabetes mellitus in humans are presented in the analytical review. Inaccordance with current insights, obesity and type 2 diabetes are considered diseases of inflammatory nature, characterized by systemic chronic low-grade inflammation, where different kinds of cytokines are cardinally involved. Unfavourable life style, i.e. excessive, high-energy, and irrational nutrition--an excessive consumption of animal fats and foods containing the high amount of glucose and starch with an insufficient use of high fiber vegetables, fish and vitamin D, and also sedentary, inactive life style leads to adipocyte hypertrophy and migration of M1 macrophages into the adipose tissue (AT). As a result, there is a low-grade inflammation accompanied by an increased production of proinflammatory cytokines (IL-1, IL-6, TNF-α, etc.), adipokines (leptin, resistin, visfatin etc.) and chemokines (CCL2, CCL5, CCL26 and CX3C). Under the influence of these cytokines, on the one hand, IR "is emerged", and on the other--there is apoptosis of the β-cells, that should be followed by the occurrence of clinically diagnosed type 2 diabetes. However, there is also the opposite system in humans, protecting the organism from the development of type 2 diabetes, and including an increase in the formation of M2 macrophages and the increased formation of secretion of antidiabetic cytokines (IL-4, IL-10, IL-13, etc.) and adiponectin.

Here we review 18 articles that describe the design and evaluation of 1 or more games for diabetes from technical, methodological, and theoretical perspectives. We undertook searches covering the period 2010 to May 2015 in the ACM, IEEE, Journal of Medical Internet Research, Studies in Health Technology and Informatics, and Google Scholar online databases using the keywords “children,” “computer games,” “diabetes,” “games,” “type 1,” and “type 2” in various Boolean combinations. The review sets out to establish, for future research, an understanding of the current landscape of digital games designed for children with diabetes. We briefly explored the use and impact of well-established learning theories in such games. The most frequently mentioned theoretical frameworks were social cognitive theory and social constructivism. Due to the limitations of the reported evaluation methodologies, little evidence was found to support the strong promise of games for diabetes. Furthermore, we could not establish a relation between design features and the game outcomes. We argue that an in-depth discussion about the extent to which learning theories could and should be manifested in the design decisions is required. PMID:26337753
The present generation of women of childbearing age more frequently suffer from overweight, obesity, initial as well as fully established metabolic syndrome, which together with postponing motherhood until the third decade in life plays an important role in the increasing incidence of gestational diabetes (GDM) that currently affects about 1/5 of pregnant women. However the causal link between diabetes during pregnancy and metabolic diseases in the whole population is mutual. By way of epigenetic changes, maternal diabetes unfavourably programmes metabolism of the offspring, who tend to transfer the disorder to the next generations. Gestational diabetes is therefore an important link fitting into the accumulation curve of the incidence of overweight, obesity, metabolic syndrome and consequently also T2DM among the whole population. Genetic as well as epigenetic factors play a great role in the GDM pathogenesis, which is shown by the fact that this complication also affects women with normal BMI. When it comes to diagnosing GDM, we will need to manage also in future with establishing fasting glycemia and glycemia following glucose challenge (OGTT) that may include a considerable degree of measurement inaccuracy. It is therefore necessary to observe pre-analytical and analytical conditions of measurements in order to obtain a reliable result. It is a positive sign that the Czech professional associations have adopted new international criteria for diagnosing GDM which, as opposed to those valid earlier, better reflect the risk of pregnancy-related and perinatal complications.The care for gestational patients with diabetes at a low risk (due to satisfactory glycemic control through a diet or small pharmacotherapeutic doses, with an eutrophic fetus and without associated complications) is provided by an outpatient gynecologist and a diabetes specialist, they can give birth in standard maternity hospitals.

Diabetic peripheral neuropathy is the most common peripheral neuropathy in the developed world; however, not all patients with diabetes and peripheral nerve disease have a peripheral neuropathy caused by diabetes. Several (although not all) studies have drawn attention to the presence of other potential causes of a neuropathy in individuals with diabetes; 10% to 50% of individuals with diabetes may have an additional potential cause of a peripheral neuropathy and some may have more than one cause. Neurotoxic medications, alcohol abuse, vitamin B(12) deficiency, renal disease, chronic inflammatory demyelinating neuropathy, inherited neuropathy, and vasculitis are the most common additional potential causes of a peripheral neuropathy in these series. The most common disorders in the differential diagnosis of a generalized diabetic peripheral neuropathy are discussed in this article. Prospective studies to investigate the prevalence of other disorders that might be responsible for a peripheral neuropathy in individuals with diabetes are warranted.

There is currently an epidemic of diabetes in the world, principally type 2 diabetes that is linked to changing lifestyle, obesity, and increasing age of the population. Latest estimates from the International Diabetes Federation (IDF) forecasts a rise from 366 million people worldwide to 552 million by 2030. Type 1 diabetes is more common in the Northern hemisphere with the highest rates in Finland and there is evidence of a rise in some central European countries, particularly in the younger children under 5 years of age. Modifiable risk factors for progression of diabetic retinopathy (DR) are blood glucose, blood pressure, serum lipids, and smoking. Nonmodifiable risk factors are duration, age, genetic predisposition, and ethnicity. Other risk factors are pregnancy, microaneurysm count in an eye, microaneurysm formation rate, and the presence of any DR in the second eye. DR, macular edema (ME), and proliferative DR (PDR) develop with increased duration of diabetes and the rates are dependent on the above risk factors. In one study of type 1 diabetes, the median individual risk for the development of early retinal changes was 9.1 years of diabetes duration. Another study reported the 25 year incidence of proliferative retinopathy among population-based cohort of type 1 patients with diabetes was 42.9%. In recent years, people with diabetes have lower rates of progression than historically to PDR and severe visual loss, which may reflect better control of glucose, blood pressure, and serum lipids, and earlier diagnosis.

Experimentally diabetic rats have low serum 1,25-dihydroxyvitamin D, intestinal malabsorption of calcium, secondary hyperparathyroidism, and bone loss. To examine the hypothesis that abnormalities similar to those in the diabetic rat might explain human diabetic osteopenia, we studied calcium metabolism in 40 healthy control and 82 diabetic patients aged 18--75 yr [47 untreated: fasting plasma glucose (mean +/- SE), 267 +/- 8 mg/dl; 19 treated but hyperglycemic: glucose 305 +/- 24 mg/dl; 16 treated and in better control: glucose, 146 +/- 8 mg/dl]. Serum total calcium, ionic calcium, immunoreactive parathyroid hormone (Arnaud method, GP-1M and CH-12M antisera), 25-hydroxyvitamin D (Haddad method), and 1,25-dihydroxyvitamin D (Lambert method) concentrations were normal in all 3 groups of diabetics and were not significantly different from values in the control group. We determined absorption of calcium from the intestine by a double isotope method (100 mg Ca carrier; normal range, 40--80%) in 11 control and 13 untreated, uncontrolled diabetics (mean plasma glucose, 285 +/- 17 mg/dl). Absorption of calcium in controls was 60 +/- 3% and in diabetics was 56 +/- 3% (not significantly different). We have found no derangement of calcium metabolism in adults with insulin-requiring juvenile- and adult-onset diabetes regardless of treatment status. The experimental diabetic rat model does not appear to be useful for determining the pathogenesis of adult human diabetic osteopenia.

Diabetic nephropathy is the kidney disease that occurs as a result of diabetes. Cardiovascular and renal complications share common risk factors such as blood pressure, blood lipids, and glycemic control. Thus, chronic kidney disease may predict cardiovascular disease in the general population. The impact of diabetes on renal impairment changes with increasing age. Serum markers of glomerular filtration rate and microalbuminuria identify renal impairment in different segments of the diabetic population, indicating that serum markers as well as microalbuminuria tests should be used in screening for nephropathy in diabetic older people. The American Diabetes Association and the National Institutes of Health recommend Estimated glomerular filtration rate (eGFR) calculated from serum creatinine at least once a year in all people with diabetes for detection of kidney dysfunction. eGFR remains an independent and significant predictor after adjustment for conventional risk factors including age, sex, duration of diabetes, smoking, obesity, blood pressure, and glycemic and lipid control, as well as presence of diabetic retinopathy. Cystatin-C (Cys C) may in future be the preferred marker of diabetic nephropathy due differences in measurements of serum creatinine by various methods. The appropriate reference limit for Cys C in geriatric clinical practice must be defined by further research. Various studies have shown the importance of measurement of albuminuria, eGFR, serum creatinine and hemoglobin level to further enhance the prediction of end stage renal disease. PMID:21537427

Diabetes mellitus due to its high prevalence and associated complications is a major socioeconomic health problem. Diabetes is characterized by multiple macro- and microvascular complications (e.g. diabetic nephropathy, cardiomyopathy, neuropathy, retinopathy). Research efforts aim to elucidate pathophysiological mechanisms contributing to the disease process. MicroRNAs are endogenous small single stranded molecules regulating targets through mRNA cleavage or translational inhibition. MicroRNAs regulate many biological cellular functions and are often deregulated during diseases. The aim of the present article is to summarize the current knowledge of the impact of microRNAs on the development of diabetes and its associated complications including endothelial and vascular smooth muscle cell dysfunction, diabetic cardiomyopathy, diabetic nephropathy, regulation of pancreatic beta cell function as well as skeletal muscle and hepatic involvement.

Objective The study objective was to examine the association between menopause status and diabetes risk among women with glucose intolerance and to determine if menopausal status modifies response to diabetes prevention interventions. Methods The study population included women in premenopause (n=708), natural postmenopause (n=328), and bilateral oophorectomy (n=201) in the Diabetes Prevention Program (DPP), a randomized placebo-controlled trial of lifestyle intervention and metformin among glucose intolerant adults. Associations between menopause and diabetes risk were evaluated using Cox proportional hazard models that adjusted for demographic variables (age, race/ethnicity, family history of diabetes, history of gestational diabetes mellitus), waist circumference, insulin resistance and corrected insulin response. Similar models were constructed after stratification by menopause type and hormone therapy (HT) use. Results After adjustment for age, there was no association between natural menopause or bilateral oophorectomy and diabetes risk. Differences by study arm were observed in women who reported bilateral oophorectomy. In the lifestyle arm, women with bilateral oophorectomy had a lower adjusted hazard for diabetes (HR 0.19, 95% CI 0.04, 0.94), although observations were too few to determine if this was independent of HT use. No significant differences were seen in the metformin (HR 1.29, 95% CI 0.63, 2.64) or placebo arms (HR 1.37, 95% CI 0.74, 2.55). Conclusions Among women at high-risk for diabetes, natural menopause was not associated with diabetes risk and did not affect response to diabetes prevention interventions. In the lifestyle intervention, bilateral oophorectomy was associated with decreased diabetes risk. PMID:21709591

Exocrine and endocrine components of pancreas are interrelated anatomically and functionally. Exocrine pancreatic dysfunction often accompanies endocrine pancreatic impairment and vice versa. Diabetes mellitus resulting from alterations of exocrine pancreas, such as acute or chronic pancreatitis, is known as pancreatic diabetes. Hyperglycemia during acute pancreatitis (AP) can be due to abnormalities in insulin secretion, increase in counterregulatory hormones release, or decrease in glucose utilization by peripheral tissues. Causal association is suggested between diabetic ketoacidosis and AP and is attributed to alternation in metabolism of triglycerides. High blood glucose levels are associated with severe AP and constitute factor of worst prognosis. Some patients are discharged with diabetes after AP episode, while others develop diabetes during first year of follow-up. Origin and frequency of glycemic abnormalities associated with AP have not been settled yet accurately. Also, predictive factors for diabetes development and persistence after AP have not been recognized to date.

The spectrum of renal disease in patients with diabetes encompasses both diabetic kidney disease (including albuminuric and non-albuminuric phenotypes) and non-diabetic kidney disease. Diabetic kidney disease can manifest as varying degrees of renal insufficiency and albuminuria, with heterogeneity in histology reported on renal biopsy. For patients with diabetes and proteinuria, the finding of non-diabetic kidney disease alone or superimposed on the changes of diabetic nephropathy is increasingly reported. It is important to identify non-diabetic kidney disease as some forms are treatable, sometimes leading to remission. Clinical indications for a heightened suspicion of non-diabetic kidney disease and hence consideration for renal biopsy in patients with diabetes and nephropathy include absence of diabetic retinopathy, short duration of diabetes, atypical chronology, presence of haematuria or other systemic disease, and the nephrotic syndrome.
Total health care expenditure in 2006 was $2.1 trillion. This figure is estimated to double within the next few years as the cost of treating diabetes and other chronic conditions continues to rise. Moreover, the baby boomer demographic is anticipated to place an enormous burden on the health care system and employer-based health insurance premiums were increased at rates as high as 10% per year in 2006. The quest to address these challenges has also created opportunities for investment, particularly in the fields of telemedicine, health care information technology, and medical technology. The author shares his business perspective, informed by years of experience as a physician and astronaut at NASA, and describes new applications of exciting technologies that deliver effective and efficient health care to diabetes patients, no matter where they may be.

An explosion of work over the last decade has produced insight into the multiple hereditary causes of a nonimmunological form of diabetes diagnosed most frequently within the first 6 months of life. These studies are providing increased understanding of genes involved in the entire chain of steps that control glucose homeostasis. Neonatal diabetes is now understood to arise from mutations in genes that play critical roles in the development of the pancreas, of β-cell apoptosis and insulin processing, as well as the regulation of insulin release. For the basic researcher, this work is providing novel tools to explore fundamental molecular and cellular processes. For the clinician, these studies underscore the need to identify the genetic cause underlying each case. It is increasingly clear that the prognosis, therapeutic approach, and genetic counseling a physician provides must be tailored to a specific gene in order to provide the best medical care.

Gestational diabetes (GDM) is defined as any degree of glucose intolerance with onset during pregnancy and is associated with increased feto-maternal morbidity as well as long-term complications in mothers and offspring. Women detected to have diabetes early in pregnancy receive the diagnosis of overt, non-gestational, diabetes (glucose: fasting > 126 mg/dl, spontaneous > 200 mg/dl or HbA1c > 6.5 % before 20 weeks of gestation). GDM is diagnosed by an oral glucose tolerance test (OGTT) or fasting glucose concentrations (> 92 mg/dl). Screening for undiagnosed type 2 diabetes at the first prenatal visit (Evidence level B) is recommended in women at increased risk using standard diagnostic criteria (high risk: history of GDM or pre-diabetes (impaired fasting glucose or impaired glucose tolerance); malformation, stillbirth, successive abortions or birth weight > 4,500 g in previous pregnancies; obesity, metabolic syndrome, age > 45 years, vascular disease; clinical symptoms of diabetes (e. g. glucosuria)). Performance of the OGTT (120 min; 75 g glucose) may already be indicated in the first trimester in some women but is mandatory between 24 and 28 gestational weeks in all pregnant women with previous non-pathological glucose metabolism (Evidence level B). Based on the results of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study GDM is defined, if fasting venous plasma glucose exceeds 92 mg/dl or 1 h 180 mg/dl or 2 h 153 mg/dl after glucose loading (OGTT; international consensus criteria). In case of one pathological value a strict metabolic control is mandatory. This diagnostic approach was recently also recommended by the WHO. All women should receive nutritional counseling and be instructed in blood glucose self-monitoring and to increase physical activity to moderate intensity levels- if not contraindicated. If blood glucose levels cannot be maintained in the normal range (fasting < 95 mg/dl and 1 h after meals < 140 mg/dl) insulin

The objective of the present study is to review hemorheological disorders in diabetes mellitus. Several key hemorheological parameters, such as whole blood viscosity, erythrocyte deformability, and aggregation, are examined in the context of elevated blood glucose level in diabetes. The erythrocyte deformability is reduced, whereas its aggregation increases, both of which make whole blood more viscous compared to healthy individuals. The present paper explains how the increased blood viscosity adversely affects the microcirculation in diabetes, leading to microangiopathy. PMID:19885302

Several dermatoses are routinely associated with diabetes mellitus, especially in patients with chronic disease. This relationship can be easily proven in some skin disorders, but it is not so clear in others. Dermatoses such necrobiosis lipoidica, granuloma annulare, acanthosis nigricans and others are discussed in this text, with an emphasis on proven link with the diabetes or not, disease identification and treatment strategy used to control those dermatoses and diabetes.

Diabetic embryopathy is a theoretical enigma and a clinical challenge. Both type 1 and type 2 diabetic pregnancy carry a significant risk for fetal maldevelopment, and the precise reasons for the diabetes-induced teratogenicity are not clearly identified. The experimental work in this field has revealed a partial, however complex, answer to the teratological question, and we will review some of the latest suggestions. PMID:27117607

Diabetes mellitus entails significant health problems worldwide. The pathogenesis of diabetes is multifactorial, resulting from interactions of both genetic and environmental factors that trigger a complex network of pathophysiological events, with metabolic and hemodynamic alterations. In this context, inflammation has emerged as a key pathophysiology mechanism. New pathogenic pathways will provide targets for prevention or future treatments. This review will focus on the implications of inflammation in diabetes mellitus, with special attention to inflammatory cytokines. PMID:25126391

Background Diabetes self-management is complex and demanding, and isolation and burnout are common experiences. The Internet provides opportunities for people with diabetes to connect with one another to address these challenges. The aims of this paper are to introduce readers to the platforms on which Diabetes Online Community (DOC) participants interact, to discuss reasons for and risks associated with diabetes-related online activity, and to review research related to the potential impact of DOC participation on diabetes outcomes. Methods Research and online content related to diabetes online activity is reviewed, and DOC writing excerpts are used to illustrate key themes. Guidelines for meaningful participation in DOC activities for people with diabetes, families, health care providers, and industry are provided. Results Common themes around DOC participation include peer support, advocacy, self-expression, seeking and sharing diabetes information, improving approaches to diabetes data management, and humor. Potential risks include access to misinformation and threats to individuals’ privacy, though there are limited data on negative outcomes resulting from such activities. Likewise, few data are available regarding the impact of DOC involvement on glycemic outcomes, but initial research suggests a positive impact on emotional experiences, attitudes toward diabetes, and engagement in diabetes management behaviors. Conclusion The range of DOC participants, activities, and platforms is growing rapidly. The Internet provides opportunities to strengthen communication and support among individuals with diabetes, their families, health care providers, the health care industry, policy makers, and the general public. Research is needed to investigate the impact of DOC participation on self-management, quality of life, and glycemic control, and to design and evaluate strategies to maximize its positive impact.

Problems of the diabetic foot are frequent. The magnitude of the clinical picture and morbidity mirrors the severity and complexity of the underlying pathobiology. The three pathogenetic mechanism involved are ischemia, neuropathy and infection. Seldom do these mechanisms work in isolation, rather most foot problems result from a complex interplay among all three. The clinical picture of the diabetic foot reaches from the neuropathic deformity with diminished or absent sensation of pain to limited gangrene or superficial ulcer. The polymicrobial infection leads to extensive tissue destruction (plantarphlegmone) with osteomyelitis. The patients often notes no pain and may become aware of the infection only through the presence of drainage or a foul odor. These infections are usually more extensive than would be predicted by clinical signs and symptoms. These lesions must be debrided and drained promptly and completely. This often requires amputations of one or more toes, combined with an incision along the entire course of the infected track on the plantar or dorsal aspect of the foot. Cultures should be taken from the depth of the wound. Initial treatment should be with broad-spectrum antibiotics, with subsequent adjustment based on culture results. The diabetic foot is a clinical problem that can be solved with a high degree of success when the approached by an interdisciplinary team (specialists in infectious and vascular disease, podiatry and diabetology). Arterial reconstruction should be designed to restore maximum perfusion to the foot. The most effective result can be obtained with infra-inguinal vein bypass with distal anastomosis to the most proximal artery with direct continuity to the ischemic territory. The single most important factor in the achievement of the reduction of amputation is the autologous vein bypass. The overall outcome in the diabetic patient in terms of graft patency and limb salvage is equal to that in the nondiabetic.
Cystic fibrosis related diabetes (CFRD) is a common complication of cystic fibrosis, caused by a fall in insulin secretion with age in individuals with pancreatic insufficiency. CFRD is associated with worse clinical status and increased mortality. Treatment of CFRD with insulin results in sustained improvements in lung function and nutrition. While clinical experience with insulin treatment in CF has increased, the selection of who to treat and glycaemic targets remain unclear.

Diabetes insipidus (DI) is one of the common disorders affecting sodium and water homeostasis, and results when ADH is either inadequately produced, or unable to negotiate its actions on the renal collecting tubules through aquaporins. The diagnostic algorithm starts with exclusion of other causes of polyuria and establishing low urine osmolality in the presence of high serum osmolality. In this paper, we have reviewed the diagnosis, etiology and management of DI in children, with special emphasis on recent advances in the field.

Pirfenidone is an oral antifibrotic agent that benefits diabetic nephropathy in animal models, but whether it is effective for human diabetic nephropathy is unknown. We conducted a randomized, double-blind, placebo-controlled study in 77 subjects with diabetic nephropathy who had elevated albuminuria and reduced estimated GFR (eGFR) (20 to 75 ml/min per 1.73 m2). The prespecified primary outcome was a change in eGFR after 1 year of therapy. We randomly assigned 26 subjects to placebo, 26 to pirfenidone at 1200 mg/d, and 25 to pirfenidone at 2400 mg/d. Among the 52 subjects who completed the study, the mean eGFR increased in the pirfenidone 1200-mg/d group (+3.3 ± 8.5 ml/min per 1.73 m2) whereas the mean eGFR decreased in the placebo group (−2.2 ± 4.8 ml/min per 1.73 m2; P = 0.026 versus pirfenidone at 1200 mg/d). The dropout rate was high (11 of 25) in the pirfenidone 2400-mg/d group, and the change in eGFR was not significantly different from placebo (−1.9 ± 6.7 ml/min per 1.73 m2). Of the 77 subjects, 4 initiated hemodialysis in the placebo group, 1 in the pirfenidone 2400-mg/d group, and none in the pirfenidone 1200-mg/d group during the study (P = 0.25). Baseline levels of plasma biomarkers of inflammation and fibrosis significantly correlated with baseline eGFR but did not predict response to therapy. In conclusion, these results suggest that pirfenidone is a promising agent for individuals with overt diabetic nephropathy. PMID:21511828

Gestational diabetes (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy and is associated with increased feto-maternal morbidity as well as long-term complications in mothers and offspring. GDM is diagnosed by an oral glucose tolerance test (OGTT) or fasting glucose concentrations in the diabetic range. In case of a high risk for GDM/type 2 diabetes (history of GDM or prediabetes [impaired fasting glucose or impaired glucose tolerance]; malformation, stillbirth, successive abortions or birth-weight > 4500 g in previous pregnancies) performance of the OGTT (120 min; 75 g glucose) is recommended already in the first trimester and--if normal--the OGTT should be repeated in the second/third trimester. In case of clinical symptoms of diabetes (glucosuria, macrosomia) the test has to be performed immediately. All other women should undergo a diagnostic test between 24 and 28 gestational weeks. If fasting plasma glucose exceeds 95 mg/dl, 1 h 180 mg/dl and 2 hrs 155 mg/dl after glucose loading (OGTT) the woman is classified as GDM (one pathological value is sufficient). In this case a strict metabolic control is mandatory. All women should receive nutritional counseling and be instructed in blood glucose self-monitoring. If blood glucose levels cannot be maintained in the normal range (fasting < 95 mg/dl and 1 h after meals < 130 mg/dl) insulin therapy should be initiated. Maternal and fetal monitoring is required in order to minimize maternal and fetal/neonatal morbidity and perinatal mortality. After delivery all women with GDM have to be reevaluated as to their glucose tolerance by a 75 g OGTT (WHO criteria).

OBJECTIVE: To evaluate the clinical, electrophysiologic, autonomic, and neuropathologic characteristics and the natural history of subacute diabetic proximal neuropathy and its response to immunotherapy. MATERIAL AND METHODS: For the 12-year period from 1983 to 1995, we conducted a retrospective review of medical records of Mayo Clinic patients with diabetes who had subacute onset and progression of proximal weakness. The responses of treated versus untreated patients were compared statistically. RESULTS: During the designated study period, 44 patients with subacute diabetic proximal neuropathy were encountered. Most patients were middle-aged or elderly, and no sex preponderance was noted. The proximal muscle weakness often was associated with reduced or absent lower extremity reflexes. Associated weight loss was a common finding. Frequently, patients had some evidence of demyelination on nerve conduction studies, but it invariably was accompanied by concomitant axonal degeneration. The cerebrospinal fluid protein concentration was usually increased. Diffuse and substantial autonomic failure was generally present. In most cases, a sural nerve biopsy specimen suggested demyelination, although evidence of an inflammatory infiltrate was less common. Of 12 patients who received treatment (with prednisone, intravenous immune globulin, or plasma exchange), 9 had improvement of their conditions, but 17 of 29 untreated patients (59%) with follow-up also eventually had improvement, albeit at a much slower rate. Improvement was usually incomplete. CONCLUSION: We suggest that the entity of subacute diabetic proximal neuropathy is an extensive and severe variant of bilateral lumbosacral radiculoplexopathy, with some features suggestive of an immune-mediated cause. It differs from chronic inflammatory demyelinating polyradiculoneuropathy in that most cases have a more restricted distribution and seem to be monophasic and self-limiting. The efficacy of immunotherapy is unproved

Neonatal diabetes mellitus is a rare condition (1/90,000 to 1/260,000 live births) defined as mild-to-severe hyperglycemia within the first year of life. Permanent neonatal diabetes mellitus requires lifelong therapy, whereas transient form resolves early in life but may relapse later on. Two main physiopathological mechanisms may explain this disease: β cell functional impairment or absence (pancreas agenesis or β cells destruction). The main genetic causes of β cells impairment are 6q24 abnormalities and mutations in ABCC8 or KCNJ11 potassium channel (KATP channel) genes. Compared to the KATP subtype, the 6q24 subtype had specific features: developmental defects involving the heart, kidneys, or urinary tract, intrauterine growth restriction, and early diagnosis. Remission of neonatal diabetes mellitus occurred in 51% of probands at a median age of 17 weeks. Recurrence was common at pubertal age, with no difference between the 6q24 and KATP-channel groups (82% vs 86%, p=0.36, respectively). Patients with mutations in ABCC8 or KCNJ11 genes had developmental delay with or without epilepsy but also developmental coordination disorder (particularly visual-spatial dyspraxia) or attention deficits in all of those who underwent in-depth neuropsychomotor investigations.

Diabetes insipidus is an uncommon pathology; its incidence varies from two to six cases in 100,000 pregnancies. It has multiple etiologies and it is classified in central and neurogenic. Patients with diabetes insipidus generally show intense thirst, polyuria, neurologic symptoms and hypernatremia. It does not seem to alter the patient's fertility. Diabetes insipidus is usually associated with pre-eclampsia, HELLP syndrome, and fatty liver disease of pregnancy. This is a report of a case seen at the Hospital General de Cholula, in Puebla, Mexico. A 19 year-old female, with 37.2 weeks of pregnancy, had a history of Langerhans cell histiocytosis since she was four years. Patient was treated with intranasal desmopressin until 2005. She went to an obstetric evaluation; laboratory and cabinet studies were obtained. A healthy 1900 g female was obtained through vaginal delivery, with a 7/9 Apgar score. We should be familiarized with this uncommon pathology because of its association with several obstetric emergencies.

Molecular cascades responsible for Ca(2+) homeostasis and Ca(2+) signalling could be assembled in highly plastic toolkits that define physiological adaptation of cells to the environment and which are intimately involved in all types of cellular pathology. Control over Ca(2+) concentration in different cellular compartments is intimately linked to cell metabolism, because (i) ATP production requires low Ca(2+), (ii) Ca(2+) homeostatic systems consume ATP and (iii) Ca(2+) signals in mitochondria stimulate ATP synthesis being an essential part of excitation-metabolic coupling. The communication between the ER and mitochondria plays an important role in this metabolic fine tuning. In the insulin resistance state and diabetes this communication has been impaired leading to different disorders, for instance, diminished insulin production by pancreatic β cells, reduced heart and skeletal muscle contractility, reduced NO production by endothelial cells, increased glucose production by liver, increased lipolysis by adipose cells, reduced immune responses, reduced cognitive functions, among others. All these processes eventually trigger degenerative events resulting in overt diabetes due to reduction of pancreatic β cell mass, and different complications of diabetes, such as retinopathy, nephropathy, neuropathy, and different cardiovascular diseases.

Vitamin D deficiency has been linked to the onset of diabetes. This review summarizes the role of Vitamin D in maintaining the normal release of insulin by the pancreatic beta cells (β-cells). Diabetes is initiated by the onset of insulin resistance. The β-cells can overcome this resistance by releasing more insulin, thus preventing hyperglycaemia. However, as this hyperactivity increases, the β-cells experience excessive Ca(2+) and reactive oxygen species (ROS) signalling that results in cell death and the onset of diabetes. Vitamin D deficiency contributes to both the initial insulin resistance and the subsequent onset of diabetes caused by β-cell death. Vitamin D acts to reduce inflammation, which is a major process in inducing insulin resistance. Vitamin D maintains the normal resting levels of both Ca(2+) and ROS that are elevated in the β-cells during diabetes. Vitamin D also has a very significant role in maintaining the epigenome. Epigenetic alterations are a feature of diabetes by which many diabetes-related genes are inactivated by hypermethylation. Vitamin D acts to prevent such hypermethylation by increasing the expression of the DNA demethylases that prevent hypermethylation of multiple gene promoter regions of many diabetes-related genes. What is remarkable is just how many cellular processes are maintained by Vitamin D. When Vitamin D is deficient, many of these processes begin to decline and this sets the stage for the onset of diseases such as diabetes.

ABSTRACT The effects of type 1 and type 2 diabetes on the body's physiological response to thermal stress is a relatively new topic in research. Diabetes tends to place individuals at greater risk for heat-related illness during heat waves and physical activity due to an impaired capacity to dissipate heat. Specifically, individuals with diabetes have been reported to have lower skin blood flow and sweating responses during heat exposure and this can have important consequences on cardiovascular regulation and glycemic control. Those who are particularly vulnerable include individuals with poor glycemic control and who are affected by diabetes-related complications. On the other hand, good glycemic control and maintenance of aerobic fitness can often delay the diabetes-related complications and possibly the impairments in heat loss. Despite this, it is alarming to note the lack of information regarding diabetes and heat stress given the vulnerability of this population. In contrast, few studies have examined the effects of cold exposure on individuals with diabetes with the exception of its therapeutic potential, particularly for type 2 diabetes. This review summarizes the current state of knowledge regarding the impact of diabetes on heat and cold exposure with respect to the core temperature regulation, cardiovascular adjustments and glycemic control while also considering the beneficial effects of maintaining aerobic fitness.

Cats are one of the few species that develop a form of diabetes mellitus that is clinically and histologically analogous to human type 2 diabetes mellitus. Figure 9 summarizes the etiologic factors thought to be involved in the development of feline and human type 2 diabetes. The main metabolic characteristics of type 2 diabetes mellitus are impaired insulin secretion and resistance to the action of insulin in its target tissues. Impaired beta cell function occurs before histologic changes become evident. The characteristic histologic finding in cats with type 2 diabetes is deposition of amyloid in pancreatic islets. Amyloid deposition occurs before the onset of clinical signs, but does not seem to be the primary defect. Pancreatic amyloid is derived form the recently discovered pancreatic hormone amylin. Amylin is synthesized in pancreatic beta cells, and is co-stored and co-secreted with insulin. Amylin has been postulated to be involved in the pathogenesis of feline diabetes mellitus both through its metabolic effects, which include inhibition of insulin secretion and induction of insulin resistance, and via progressive amyloid deposition and beta cell degeneration. Increased amylin concentration has been documented intracellularly in cats with impaired glucose tolerance and in the plasma of diabetic cats, and supports the hypothesis that amylin is involved in the pathogenesis of type 2 diabetes. Obesity is a common finding in diabetic felines and is a contributing factor to the insulin resistance present in type 2 diabetes. Clinical signs of diabetes develop once total insulin secretion decreases to 20% to 25% of normal levels. Many diabetic cats have been treated successfully with oral hypoglycemics, but 50% to 70% of diabetic cats are insulin dependent. Based on histologic evidence, this is the result of extensive amyloid deposition and subsequent beta cell degeneration, rather than autoimmune destruction of pancreatic beta cells associated with type 1
Sexual dysfunction is common in patients with diabetes mellitus. Vascular, neurological and hormonal alterations are involved in this complication. Many studies showed altered endothelium-dependent and neurogenic relaxations in corpus cavernosum from diabetic patients with erectile dysfunction (ED). This finding has been associated with a lack of nitric oxyde (NO) production and a significant increase in NO synthase (NOS) binding sites in penile tissues, induced by diabetes. Advanced glycation endproducts (AGEs) concur to diabetic vascular complications by quenching NO activity and by increasing the expression of mediators of vascular damage such as vascular endothelial growth factor (VEGF), possessing permeabilizing and neoangiogenic effects, and endothelin-1 (ET-1), with vaso-constricting and mitogenic action. Moreover, the differential gene expression for various growth factors in penile tissues may be involved in the pathophysiology of ED associated with diabetes. Neuropathy is also likely to be an important cause of diabetic ED: morphological alterations of autonomic nerve fibers in cavernosal tissue of patients with diabetic ED have been demonstrated. Finally, androgens enhance nNOS gene expression in the penile corpus cavernosum of rats, suggesting that they play a role in maintaining NOS activity. However, sexual dysfunctions in women with diabetes has received less attention in clinical research. Several studies suggest an increased prevalence of deficient vaginal lubrication, making sexual intercourse unpleasant. Sexual dysfunction is associated with lower overall quality of marital relation and more depressive symptoms in diabetic women.

Diabetes mellitus (DM) is a disease of increasing incidence and prevalence. Arterial baroreceptors are stretch-sensitive receptors, which in a reflex manner are involved in the homeostatic control of arterial blood pressure. Diabetic subjects have depressed baroreflex sensitivity (BRS), although the exact pathomechanisms are unclear. In this review, we discuss the features, clinicaland prognostic implications of reduced BRS for diabetic patients and the potential involvement of cardiovascular autonomic neuropathy and atherosclerosis. Finally, we demonstrate evidence on interventions (e.g. pioglitazone, alpha-lipoic acid, leptin, fluvastatin, physicaltraining etc.) which could improve BRS and ameliorate cardiovascular autonomic dysfunction in diabetic patients.

Gallbladder emptying and filling was studied in eight diabetic and six normal control patients. None of the patients had gallstones. Cholescintigraphy was performed using (/sup 99m/Tc)disofenin, and gallbladder emptying was studied using a 45-min i.v. infusion of the octapeptide of cholecystokinin (OP-CCK) 20 ng/kg X hr. The peak filling rate was greater in diabetic than in normal subjects; however, emptying of the gallbladder in response to OP-CCK was significantly less in the diabetic subjects (51.6 +/- 10.4% compared with 77.2 +/- 4.9%). When the diabetic group was subdivided into obese and nonobese diabetics, the obese diabetics had a much lower percentage of emptying than the nonobese diabetics (30.0 +/- 10.4% compared with 73.1 +/- 9.3%). These findings suggest that obese diabetics may have impaired emptying of the gallbladder even in the absence of gallstones. The more rapid rate of gallbladder filling in obesity may indicate hypotonicity of the gallbladder. The combination of these abnormalities may predispose the obese diabetic to the development of gallstones.
Diabetes mellitus is known to have late complications including micro vascular and macro vascular disease. This review focuses on another possible area of complication regarding diabetes; bone. Diabetes may affect bone via bone structure, bone density, and biochemical markers of bone turnover. The aim of the present review is to examine in vivo from humans on biochemical markers of bone turnover in diabetics compared to non-diabetics. Furthermore, the effect of glycemic control on bone markers and the similarities and differences of type 1- and type 2-diabetics regarding bone markers will be evaluated. A systematic literature search was conducted using PubMed, Embase, Cinahl, and SveMed+ with the search terms: "Diabetes mellitus," "Diabetes mellitus type 1," "Insulin dependent diabetes mellitus," "Diabetes mellitus type 2," "Non-insulin dependent diabetes mellitus," "Bone," "Bone and Bones," "Bone diseases," "Bone turnover," "Hemoglobin A Glycosylated," and "HbA1C." After removing duplicates from this search 1,188 records were screened by title and abstract and 75 records were assessed by full text for inclusion in the review. In the end 43 records were chosen. Bone formation and resorption markers are investigated as well as bone regulating systems. T1D is found to have lower osteocalcin and CTX, while osteocalcin and tartrate-resistant acid are found to be lower in T2D, and sclerostin is increased and collagen turnover markers altered. Other bone turnover markers do not seem to be altered in T1D or T2D. A major problem is the lack of histomorphometric studies in humans linking changes in turnover markers to actual changes in bone turnover and further research is needed to strengthen this link.

The Malaysian Ministry of Health has undertaken various campaigns on healthy lifestyle and health promotion over the years. The impact of these campaigns has been mixed and not well documented. This cross-sectional study evaluated the knowledge level of patients with and without diabetes in a large urban polyclinic using a 41-item questionnaire. One hundred and forty-nine adults (83 with diabetes, 66 without diabetes) participated in this study. Patients with diabetes had higher overall knowledge scores than those without diabetes (81.8% vs 64.0%, p < 0.001). While the overall knowledge of patients without diabetes appeared to be acceptable, several areas of knowledge deficiency were identified in this group--areas that should be filled by the on-going health promotion activities.

Autonomic neuropathy, once considered to be the Cinderella of diabetes complications, has come of age. The autonomic nervous system innervates the entire human body, and is involved in the regulation of every single organ in the body. Thus, perturbations in autonomic function account for everything from abnormalities in pupillary function to gastroparesis, intestinal dysmotility, diabetic diarrhea, genitourinary dysfunction, amongst others. "Know autonomic function and one knows the whole of medicine!" It is now becoming apparent that before the advent of severe pathological damage to the autonomic nervous system there may be an imbalance between the two major arms, namely the sympathetic and parasympathetic nerve fibers that innervate the heart and blood vessels, resulting in abnormalities in heart rate control and vascular dynamics. Cardiac autonomic neuropathy (CAN) has been linked to resting tachycardia, postural hypotension, orthostatic bradycardia and orthostatic tachycardia (POTTS), exercise intolerance, decreased hypoxia-induced respiratory drive, loss of baroreceptor sensitivity, enhanced intraoperative or perioperative cardiovascular lability, increased incidence of asymptomatic ischemia, myocardial infarction, and decreased rate of survival after myocardial infarction and congestive heart failure. Autonomic dysfunction can affect daily activities of individuals with diabetes and may invoke potentially life-threatening outcomes. Intensification of glycemic control in the presence of autonomic dysfunction (more so if combined with peripheral neuropathy) increases the likelihood of sudden death and is a caveat for aggressive glycemic control. Advances in technology, built on decades of research and clinical testing, now make it possible to objectively identify early stages of CAN with the use of careful measurement of time and frequency domain analyses of autonomic function. Fifteen studies using different end points report prevalence rates of 1% to 90

Background Women with diabetes have a worse survival after breast cancer diagnosis compared to women without diabetes. This may be due to a different etiological profile, leading to the development of more aggressive breast cancer subtypes. Our aim was to investigate whether insulin and non-insulin treated women with diabetes develop specific clinicopathological breast cancer subtypes compared to women without diabetes. Methods and Findings This cross-sectional study included randomly selected patients with invasive breast cancer diagnosed in 2000–2010. Stratified by age at breast cancer diagnosis (≤50 and >50 years), women with diabetes were 2:1 frequency-matched on year of birth and age at breast cancer diagnosis (both in 10-year categories) to women without diabetes, to select ~300 patients with tumor tissue available. Tumor MicroArrays were stained by immunohistochemistry for estrogen and progesterone receptor (ER, PR), HER2, Ki67, CK5/6, CK14, and p63. A pathologist scored all stains and revised morphology and grade. Associations between diabetes/insulin treatment and clinicopathological subtypes were analyzed using multivariable logistic regression. Morphology and grade were not significantly different between women with diabetes (n = 211) and women without diabetes (n = 101), irrespective of menopausal status. Premenopausal women with diabetes tended to have more often PR-negative (OR = 2.44(95%CI:1.07–5.55)), HER2-negative (OR = 2.84(95%CI:1.11–7.22)), and basal-like (OR = 3.14(95%CI:1.03–9.60) tumors than the women without diabetes, with non-significantly increased frequencies of ER-negative (OR = 2.48(95%CI:0.95–6.45)) and triple negative (OR = 2.60(95%CI:0.88–7.67) tumors. After adjustment for age and BMI, the associations remained similar in size but less significant. We observed no evidence for associations of clinicopathological subtypes with diabetes in postmenopausal women, or with insulin treatment in general. Conclusions We found no

The term "brittle" is used to describe an uncommon subgroup of patients with type I diabetes whose lives are disrupted by severe glycaemic instability with repeated and prolonged hospitalization. Psychosocial problems are the major perceived underlying causes of brittle diabetes. Aim of this study is a systematic psychopathological and personological assessment of patients with brittle diabetes in comparison with subjects without brittle diabetes, using specific parameters of general psychopathology and personality disorders following the multi-axial format of the current DSM-IV-TR (Diagnostic and Statistical manual of Mental Disorders - IV Edition - Text Revised) diagnostic criteria for mental disorders. Patients comprised 42 subjects with brittle diabetes and a case-control group of 42 subjects with stable diabetes, matched for age, gender, years of education, and diabetes duration. General psychopathology and the DSM-IV-TR personality disorders were assessed using the Symptom Checklist-90-Revised (SCL-90-R) and the Structured Clinical Interview for axis II personality Disorders (SCID-II). The comparison for SCL-90-R parameters revealed no differences in all primary symptom dimensions and in the three global distress indices between the two groups. However, patients with brittle diabetes showed higher percentages in borderline, histrionic, and narcissistic personality disorder. In this study, patients with brittle diabetes show no differences in terms of global severity of psychopathological distress and specific symptoms of axis I DSM-IV-TR psychiatric diagnoses in comparison with subjects without brittle diabetes. Differently, individuals with brittle diabetes are more frequently affected by specific DSM-IV-TR cluster B personality disorders.

A patient-centered interdisciplinary diabetes care model was implemented at Vidant Medical Center in Greenville, N.C., a 909-bed tertiary care teaching hospital, for the purpose of providing all patients with diabetes clear and concise instructions on diabetes survival skills. Survival skills education during hospitalization is needed for safe transition to community resources for continued and expanded diabetes self-management education. This article describes the process used to develop, implement, and evaluate the model. This initiative achieved substantial cost savings, with no significant changes in length of stay (LOS) or diabetes readmission rates. This patient-centered model demonstrates how a team of interdisciplinary health care professionals can integrate services in providing care for a large population of patients with chronic disease.

Background: The metabolic complications and pathologic changes that occur in diabetes mellitus (DM) influence the occurrence of various dermatoses. Aim: To study the impact of control of diabetes on the pattern of cutaneous disorders. Materials and Methods: A cross-sectional descriptive study of patients attending diabetic clinic in a tertiary care hospital. A total of 500 consecutive patients were studied. Detailed history, clinical examination and relevant investigations were done to diagnose diabetic complications and cutaneous disorders. Dermatoses with or without known pathogenesis were correlated with age, gender, fasting plasma glucose (FPG), duration of diabetes, and complications of DM. Statistical analysis was carried out using Student “t” test and Chi-square test with 5% confidence interval (P value 0.05). Results: Majority of patients had well-controlled (FPG<130 mg/ml, 60%) type 2 DM (98.8%). No statistically significant difference (P>0.05) between the patients with or without DM specific cutaneous disorders was noticed with reference to age and gender distribution, duration of DM and FPG. Signs of insulin resistance, acrochordon (26.2%), and acanthosis nigricans (5%) were common, followed by fungal (13.8%) and bacterial (6.8%) infections. Eruptive xanthoma (0.6%), diabetic foot (0.2%), diabetic bulla (0.4%), diabetic dermopathy (0.2%), generalized granuloma annulare (0.2%), and insulin reactions (6.2%) and lipodystrophy (14%) were also seen. Conclusion: Well-controlled diabetes decreases the prevalence of DM-specific cutaneous disorders associated with chronic hyperglycemia. It is necessary to have a dermatologist in the diabetic clinic for early detection of potentially grave or predisposing conditions. PMID:21716540

Aim of database To monitor the development of diabetic eye disease in Denmark and to evaluate the accessibility and effectiveness of diabetic eye screening programs with focus on interregional variations. Target population The target population includes all patients diagnosed with diabetes. Denmark (5.5 million inhabitants) has ~320,000 diabetes patients with an annual increase of 27,000 newly diagnosed patients. The Danish Registry of Diabetic Retinopathy (DiaBase) collects data on all diabetes patients aged ≥18 years who attend screening for diabetic eye disease in hospital eye departments and in private ophthalmological practice. In 2014–2015, DiaBase included data collected from 77,968 diabetes patients. Main variables The main variables provide data for calculation of performance indicators to monitor the quality of diabetic eye screening and development of diabetic retinopathy. Data with respect to age, sex, best corrected visual acuity, screening frequency, grading of diabetic retinopathy and maculopathy at each visit, progression/regression of diabetic eye disease, and prevalence of blindness were obtained. Data analysis from DiaBase’s latest annual report (2014–2015) indicates that the prevalence of no diabetic retinopathy, nonproliferative diabetic retinopathy, and proliferative diabetic retinopathy is 78%, 18%, and 4%, respectively. The percentage of patients without diabetic maculopathy is 97%. The proportion of patients with regression of diabetic retinopathy (20%) is greater than the proportion of patients with progression of diabetic retinopathy (10%). Conclusion The collection of data from diabetic eye screening is still expanding in Denmark. Analysis of the data collected during the period 2014–2015 reveals an overall decrease of diabetic retinopathy compared to the previous year, although the number of patients newly diagnosed with diabetes has been increasing in Denmark. DiaBase is a useful tool to observe the quality of screening

Diabetes mellitus affects virtually every organ system in the body and the degree of organ involvement depends on the duration and severity of the disease, and other co-morbidities. Gastrointestinal (GI) involvement can present with esophageal dysmotility, gastro-esophageal reflux disease (GERD), gastroparesis, enteropathy, non alcoholic fatty liver disease (NAFLD) and glycogenic hepatopathy. Severity of GERD is inversely related to glycemic control and management is with prokinetics and proton pump inhibitors. Diabetic gastroparesis manifests as early satiety, bloating, vomiting, abdominal pain and erratic glycemic control. Gastric emptying scintigraphy is considered the gold standard test for diagnosis. Management includes dietary modifications, maintaining euglycemia, prokinetics, endoscopic and surgical treatments. Diabetic enteropathy is also common and management involves glycemic control and symptomatic measures. NAFLD is considered a hepatic manifestation of metabolic syndrome and treatment is mainly lifestyle measures, with diabetes and dyslipidemia management when coexistent. Glycogenic hepatopathy is a manifestation of poorly controlled type 1 diabetes and is managed by prompt insulin treatment. Though GI complications of diabetes are relatively common, awareness about its manifestations and treatment options are low among physicians. Optimal management of GI complications is important for appropriate metabolic control of diabetes and improvement in quality of life of the patient. This review is an update on the GI complications of diabetes, their pathophysiology, diagnostic evaluation and management. PMID:23772273

Diabetes mellitus is one of the most common serious metabolic diseases that results in hyperglycemia due to defects of insulin secretion or insulin action or both. The present review focuses on the alterations to the diabetic neuronal tissues and skeletal muscle, including stem cells in both tissues, and the preventive effects of physical activity on diabetes. Diabetes is associated with various nervous disorders, such as cognitive deficits, depression, and Alzheimer's disease, and that may be caused by neural stem cell dysfunction. Additionally, diabetes induces skeletal muscle atrophy, the impairment of energy metabolism, and muscle weakness. Similar to neural stem cells, the proliferation and differentiation are attenuated in skeletal muscle stem cells, termed satellite cells. However, physical activity is very useful for preventing the diabetic alteration to the neuronal tissues and skeletal muscle. Physical activity improves neurogenic capacity of neural stem cells and the proliferative and differentiative abilities of satellite cells. The present review proposes physical activity as a useful measure for the patients in diabetes to improve the physiological functions and to maintain their quality of life. It further discusses the use of stem cell-based approaches in the context of diabetes treatment. PMID:26075247

Diabetes mellitus is a heterogenous disorder characterized by chronic hyperglycemia and induced by a large number of etiopathogenic conditions. Beside type 1 and type 2 diabetes, which account for almost 90% of all cases, practitioners may encounter patients with more infrequent forms of diabetes, as those induced by mutations of a single gene, atypical immune disorders or neonatal diabetes. Monogenic diabetes is represented by genetic disorders in the structure of the beta-cell (the MODY syndromes and the mutations of mitochondrial DNA) or in the insulin's action (type A insulin resistance syndrome, Rabson-Mendenhall syndrome, leprechaunism, lipodystrophies). The rare forms of immune diabetes are determined by antibodies against insulin or insulin receptor or appear as a component of the "stiff man syndrome". Neonatal diabetes is induced by mutations in genes that control beta-cell development and function and may have a transient or permanent nature. Knowledge of the uncommon forms of diabetes mellitus enables physicians to apply the optimal treatment, to estimate the evolution of the patient and to apply a complete family screening in order to diagnose all other blood relatives as soon as possible.

The increasing prevalence of diabetes, the drive to develop community services for diabetes and the Quality and Outcomes Framework for diabetes have led to improvements in the management of diabetes in primary care settings, with services traditionally provided only in specialist care now provided for many patients with diabetes by non-specialists. Consequently, there is a need to redefine roles, responsibilities and components of a specialist diabetes service to provide for the needs of patients in the National Health Service (NHS) today. The delivery of diabetes care is complex and touches on almost every aspect of the health service. It is the responsibility of those working within commissioning and specialist provider roles to work together with people with diabetes to develop, organize and deliver a full range of integrated diabetes care services. The local delivery model agreed within the local diabetes network, comprising specialist teams, primary care teams, commissioners and people with diabetes, should determine how the diabetes specialist services are organizsed. It should identify the roles and responsibilities of provider organizations to ensure that the right person provides the right care, at the right time, and in the right place. We summarize a report entitled 'Commissioning Diabetes Specialist Services for Adults with Diabetes', which has been produced, as a 'Task and Finish' group activity within Diabetes UK, to assist managers, commissioners and healthcare professionals to provide advice on the structure, roles and components of specialist diabetes services for adults.

Better understanding of the physiological role of the vitamin-D system, in particular its potential effects on inflammatory and autoimmune conditions as well as on insulin secretion and possibly also on insulin resistance, increased the interest in its potential role in prevention and control of the diabetic condition, both type-1 and -2 diabetes. Both these conditions are associated with inflammation and type-1 diabetes also with an autoimmune pathology. Indeed, animal and human studies support the notion that adequate vitamin-D supplementation may decrease the incidence of type-1 and possibly also of type-2 diabetes mellitus and may improve the metabolic control in the diabetes state. However, the exact mechanisms by which vitamin-D and calcium supplementation exert their beneficial effects are not clear and need further investigation.

Already at the time of diagnosis of juvenile onset diabetes mellitus, there are morphological and functional changes in the kidney. The kidneys and the individual glomeruli are considerably enlarged, and the glomerular filtration increased. In experimental diabetes mellitus the metabolism of the glomerular basement membrane is increased. These abnormalities are reversible by meticulous metabolic control. Their relationship to the diabetic glomerulosclerosis that causes uremia twenty to thirty years later is not clear. Carefully analyzed extensive clinical experience confirms that good metabolic control delays the onset of symptomatic diabetic renal disease, as expected from experimental studies. Normalization of even a slightly elevated blood pressure may be important to slow the progression of the renal insufficiency. Better methods for the management of the diabetic state and better education of the patients may be important to postpone the heroic endeavours of renal or pancreatic transplantation or dialysis.

Diabetes devices are increasingly connected wirelessly to each other and to data-displaying reader devices. Threats to the accurate flow of information and commands may compromise the function of these devices and put their users at risk of health complications. Sound cybersecurity of connected diabetes devices is necessary to maintain confidentiality, integrity, and availability of the data and commands. Diabetes devices can be hacked by unauthorized agents and also by patients themselves to extract data that are not automatically provided by product software. Unauthorized access to connected diabetes devices has been simulated and could happen in reality. A cybersecurity standard designed specifically for connected diabetes devices will improve the safety of these products and increase confidence of users that the products will be secure.

Diabetic patients frequently develop a constellation of electrolyte disorders. These disturbances are particularly common in decompensated diabetics, especially in the context of diabetic ketoacidosis or nonketotic hyperglycemic hyperosmolar syndrome. These patients are markedly potassium-, magnesium- and phosphate-depleted. Diabetes mellitus (DM) is linked to both hypo- and hyper-natremia reflecting the coexistence of hyperglycemia-related mechanisms, which tend to change serum sodium to opposite directions. The most important causal factor of chronic hyperkalemia in diabetic individuals is the syndrome of hyporeninemic hypoaldosteronism. Impaired renal function, potassium-sparing drugs, hypertonicity and insulin deficiency are also involved in the development of hyperkalemia. This article provides an overview of the electrolyte disturbances occurring in DM and describes the underlying mechanisms. This insight should pave the way for pathophysiology-directed therapy, thus contributing to the avoidance of the several deleterious effects associated with electrolyte disorders and their treatment.

Despite intensive research efforts over the past few decades, the mechanisms underlying the etiology of sporadic Alzheimer's disease (AD) remain unknown. This fact is of major concern because the number of patients affected by this medical condition is increasing exponentially and the existing treatments are only palliative in nature and offer no disease modifying affects. Interestingly, recent epidemiological studies indicate that diabetes significantly increases the risk of developing AD, suggesting that diabetes may play a causative role in the development of AD pathogenesis. Therefore, elucidating the molecular interactions between diabetes and AD is of critical significance because it might offer a novel approach to identifying mechanisms that may modulate the onset and progression of sporadic AD cases. This review highlights the involvement of several novels pathological molecular mechanisms induced by diabetes that increase AD pathogenesis. Furthermore, we discuss novel findings in animal model and clinical studies involving the use of anti-diabetic compounds as promising therapeutics for AD.

Neuropathy is a common complication of diabetes mellitus (DM) with a wide clinical spectrum that encompasses generalized to focal and multifocal forms. Entrapment neuropathies (EN), which are focal forms, are so frequent at any stage of the diabetic disease, that they may be considered a neurophysiological hallmark of peripheral nerve involvement in DM. Indeed, EN may be the earliest neurophysiological abnormalities in DM, particularly in the upper limbs, even in the absence of a generalized polyneuropathy, or it may be superimposed on a generalized diabetic neuropathy. This remarkable frequency of EN in diabetes is underlain by a peculiar pathophysiological background. Due to the metabolic alterations consequent to abnormal glucose metabolism, the peripheral nerves show both functional impairment and structural changes, even in the preclinical stage, making them more prone to entrapment in anatomically constrained channels. This review discusses the most common and relevant EN encountered in diabetic patient in their epidemiological, pathophysiological and diagnostic features. PMID:27660694

Diabetic retinopathy remains a major cause of worldwide preventable blindness. The vitreo-retinal interface plays a critical role in the pathogenesis of diabetic retinopathy. The term pharmacologic vitreolysis refers to the use of enzymes to liquefy the vitreous gel, and to induce posterior vitreous detachment (PVD). Intravitreal ovine hyaluronidase injection was effective in clearing vitreous hemorrhage. Several human case series demonstrated that intravitreal injection of autologous plasmin enzyme was a safe and effective adjunct to vitreous surgery for the treatment of diabetic macular edema and proliferative diabetic retinopathy. Recently, it was shown that intravitreal injection of plasmin enzyme without the performance of vitrectomy induced complete PVD and reduced macular thickening due to refractory diabetic macular edema.

Diabetes devices are increasingly connected wirelessly to each other and to data-displaying reader devices. Threats to the accurate flow of information and commands may compromise the function of these devices and put their users at risk of health complications. Sound cybersecurity of connected diabetes devices is necessary to maintain confidentiality, integrity, and availability of the data and commands. Diabetes devices can be hacked by unauthorized agents and also by patients themselves to extract data that are not automatically provided by product software. Unauthorized access to connected diabetes devices has been simulated and could happen in reality. A cybersecurity standard designed specifically for connected diabetes devices will improve the safety of these products and increase confidence of users that the products will be secure.

Psychiatric disorders and psychological problems are common in patients with diabetes mellitus. There is a twofold increase in depression which is associated with suboptimal glycemic control and increased morbidity and mortality. Other psychiatric disorders with a higher incidence of diabetes mellitus are cognitive impairment, dementia, disturbed eating behaviour, anxiety disorders, schizophrenia, bipolar disorders and borderline personality disorder. The coincidence of mental disorders and diabetes mellitus has unfavourable influences on metabolic control and micro- and macroangiopathic late complications. Improvement of therapeutic outcome is a challenge in the modern health care system. The intentions behind this position paper are to rise awareness of this special set of problems, to intensify cooperation between involved health care providers and to reduce incidence of diabetes mellitus as well as morbidity and mortality from diabetes in this patient group.

People with diabetes mellitus are at increased risk of cognitive dysfunction. This review explores the relation between caffeine intake, diabetes, cognition and dementia, focusing on type 2 diabetes (T2DM). Epidemiological studies on caffeine/coffee intake and T2DM risk are reviewed. Next, the impact of T2DM on cognition is addressed. Finally, the potential for caffeine to modulate the risk of cognitive decline in the context of diabetes is explored. The conclusion is that, although epidemiological studies indicate that coffee/caffeine consumption is associated with a decreased risk of T2DM and possibly also with a decreased dementia risk, we can at present not be certain that these associations are causal. For now, recommendations for coffee consumption in individuals with T2DM or pre-diabetic stages are therefore difficult to establish, but it should be acknowledged that caffeine does appear to have several properties that warrant further investigations in this field.
The development of type I diabetes in the nonobese diabetic (NOD) mouse is under the control of multiple genes, one or more of which is linked to the major histocompatibility complex (MHC). The MHC class II region has been implicated in disease development, with expression of an I-E transgene in NOD mice shown to provide protection from insulitis and diabetes. To examine the effect of expressing an I-E+ or I-E- non-NOD MHC on the NOD background, three I-E+ and three I-E- NOD MHC congenic strains (NOD.H-2i5, NOD.H-2k, and NOD.H-2h2, and NOD.H-2h4, NOD.H-2i7, and NOD.H-2b, respectively) were developed. Of these strains, both I-E+ NOD.H-2h2 and I-E- NOD.H-2h4 mice developed insulitis, but not diabetes. The remaining four congenic strains were free of insulitis and diabetes. These results indicate that in the absence of the NOD MHC, diabetes fails to develop. Each NOD MHC congenic strain was crossed with the NOD strain to produce I-E+ and I-E- F1 mice; these mice thus expressed one dose of the NOD MHC and one dose of a non-NOD MHC on the NOD background. While a single dose of a non-NOD MHC provided a large degree of disease protection to all of the F1 strains, a proportion of I-E+ and I-E- F1 mice aged 5-12 mo developed insulitis and cyclophosphamide-induced diabetes. When I-E+ F1 mice were aged 9-17 mo, spontaneous diabetes developed as well. These data are the first to demonstrate that I-E+ NOD mice develop diabetes, indicating that expression of I-E in NOD mice is not in itself sufficient to prevent insulitis or diabetes. In fact, I-E- F1 strains were no more protected from diabetes than I-E+ F1 strains, suggesting that other non-NOD MHC- linked genes are important in protection from disease. Finally, transfer of NOD bone marrow into irradiated I-E+ F1 recipients resulted in high incidences of diabetes, indicating that expression of non-NOD MHC products in the thymus, in the absence of expression in bone marrow- derived cells, is not sufficient to provide protection

The optical coherence tomography (OCT), a noninvasive and noncontact diagnostic method, was introduced in 1995 for imaging macular diseases. In diabetic macular edema (DME), OCT scans show hyporeflectivity, due to intraretinal and/or subretinal fluid accumulation, related to inner and/or outer blood-retinal barrier breakdown. OCT tomograms may also reveal the presence of hard exudates, as hyperreflective spots with a shadow, in the outer retinal layers, among others. In conclusion, OCT is a particularly valuable diagnostic tool in DME, helpful both in the diagnosis and follow-up procedure.

Diabetes mellitus is one of the most common diagnoses made by family physicians. Uncontrolled diabetes can lead to blindness, limb amputation, kidney failure, and vascular and heart disease. Screening patients before signs and symptoms develop leads to earlier diagnosis and treatment, but may not reduce rates of end-organ damage. Randomized trials show that screening for type 2 diabetes does not reduce mortality after 10 years, although some data suggest mortality benefits after 23 to 30 years. Lifestyle and pharmacologic interventions decrease progression to diabetes in patients with impaired fasting glucose or impaired glucose tolerance. Screening for type 1 diabetes is not recommended. The U.S. Preventive Services Task Force recommends screening for abnormal blood glucose and type 2 diabetes in adults 40 to 70 years of age who are overweight or obese, and repeating testing every three years if results are normal. Individuals at higher risk should be considered for earlier and more frequent screening. The American Diabetes Association recommends screening for type 2 diabetes annually in patients 45 years and older, or in patients younger than 45 years with major risk factors. The diagnosis can be made with a fasting plasma glucose level of 126 mg per dL or greater; an A1C level of 6.5% or greater; a random plasma glucose level of 200 mg per dL or greater; or a 75-g two-hour oral glucose tolerance test with a plasma glucose level of 200 mg per dL or greater. Results should be confirmed with repeat testing on a subsequent day; however, a single random plasma glucose level of 200 mg per dL or greater with typical signs and symptoms of hyperglycemia likely indicates diabetes. Additional testing to determine the etiology of diabetes is not routinely recommended.

Burgeoning levels of diabetes are a major concern for dialysis services, as diabetes is now the most common cause of end-stage renal disease in most developed nations. With the rapid rise in diabetes prevalence in developing countries, the burden of end stage renal failure due to diabetes is also expected to rise in such countries. Diabetic patients on dialysis have a high burden of morbidity and mortality, particularly from cardiovascular disease, and a higher societal and economic cost compared to non-diabetic subjects on dialysis. Tight glycaemic and blood pressure control in diabetic patients has an important impact in reducing risk of progression to end stage renal disease. The evidence for improving glycaemic control in patients on dialysis having an impact on mortality or morbidity is sparse. Indeed, many factors make improving glycaemic control in patients on dialysis very challenging, including therapeutic difficulties with hypoglycaemic agents, monitoring difficulties, dialysis strategies that exacerbate hyperglycaemia or hypoglycaemia, and possibly a degree of therapeutic nihilism or inertia on the part of clinical diabetologists and nephrologists. Standard drug therapy for hyperglycaemia (eg, metformin) is clearly not possible in patients on dialysis. Thus, sulphonylureas and insulin have been the mainstay of treatment. Newer therapies for hyperglycaemia, such as gliptins and glucagon-like peptide-1 analogues have become available, but until recently, renal failure has precluded their use. Newer gliptins, however, are now licensed for use in 'severe renal failure', although they have yet to be trialled in dialysis patients. Diabetic patients on dialysis have special needs, as they have a much greater burden of complications (cardiac, retinal and foot). They may be best managed in a multidisciplinary diabetic-renal clinic setting, using the skills of diabetologists, nephrologists, clinical nurse specialists in nephrology and diabetes, along with

Aims To determine if the presence of diabetes autoantibodies predicts the development of diabetes among participants in the Diabetes Prevention Program. Methods A total of 3050 participants were randomized into three treatment groups: intensive lifestyle intervention, metformin and placebo. Glutamic acid decarboxylase (GAD) 65 autoantibodies and insulinoma-associated-2 autoantibodies were measured at baseline and participants were followed for 3.2 years for the development of diabetes. Results The overall prevalence of GAD autoantibodies was 4.0%, and it varied across racial/ethnic groups from 2.4% among Asian-Pacific Islanders to 7.0% among non-Hispanic black people. There were no significant differences in BMI or metabolic variables (glucose, insulin, HbA1c, estimated insulin resistance, corrected insulin response) stratified by baseline GAD antibody status. GAD autoantibody positivity did not predict diabetes overall (adjusted hazard ratio 0.98; 95% CI 0.56–1.73) or in any of the three treatment groups. Insulinoma-associated-2 autoantibodies were positive in only one participant (0.033%). Conclusions These data suggest that ‘diabetes autoimmunity’, as reflected by GAD antibodies and insulinoma-associated-2 autoantibodies, in middle-aged individuals at risk for diabetes is not a clinically relevant risk factor for progression to diabetes.

Diabetes mellitus (DM) is a metabolic disorder in the endocrine system resulting from a defect in insulin secretion, insulin action or both of them. Adverse side effects of chemical drugs for treatment of diabetes persuaded the using of medical plants. Cherry as a traditionally used plant for treatment of diabetes, is packed with powerful plant pigments called anthocyanins. They give cherries their dark red color and are one of the richest antioxidant sources which lower the blood sugar and bear other beneficial health effects. The purpose of this study is to evaluate the effect of ethanolic extract of cherry fruit on alloxan induced diabetic rats. In this study 36 Male Wistar rats, body weight of 150-200gr were divided into 6 groups. Diabetes was induced by intra peritoneal injection of 120 mg/kg Alloxan. The duration of the cherries treatment was 30 days in which single dose of extracts (200mg/kg) were oral administered to diabetic rats. Blood glucose levels were estimated with glucometer before treatment, 2h and 1- 4 weeks after administration of extracts. Treatment with extracts of the cherries resulted in a significant reduction in blood glucose and urinary microalbumin and an increase in the creatinine secretion level in urea. Extract of this plant is useful in controlling the blood glucose level. Cherries appear to aid in diabetes control and diminution of the complications of the disease. Some relevant patents are also outlined in this article.

Epidemiologic evidence suggests that cancer incidence is associated with diabetes as well as certain diabetes risk factors and treatments. This consensus statement of experts assembled jointly by the American Diabetes Association and the American Cancer Society reviews the state of science concerning 1) the association between diabetes and cancer incidence or prognosis; 2) risk factors common to both diabetes and cancer; 3) possible biologic links between diabetes and cancer risk; and 4) whether diabetes treatments influence the risk of cancer or cancer prognosis. In addition, key unanswered questions for future research are posed.
Management of patients with Type 2 diabetes mellitus (T2DM) demands a comprehensive approach which includes diabetes education, an emphasis on life style modification, achievement of good glycemic control, minimization of cardiovascular risk, and avoidance of drugs that can aggravate glucose or lipid metabolism, and screening for diabetes complications. Comprehensive diabetes management can delay the progression of complication and maximize the quality of life. Acquiring knowledge about diabetes is an essential part of diabetes management, and even more important is to make the patient aware of this chronic disease. "For a diabetic patient, knowledge and understanding are not a part of treatment--they are the treatment".

Platelet activation plays a key role in atherothrombosis in type 2 diabetes mellitus (T2DM) and increased in vivo platelet activation with enhanced thromboxane (TX) biosynthesis has been reported in patients with impairment of glucose metabolism even in the earlier stages of disease and in the preclinical phases. In this regards, platelets appear as addresses and players carrying and transducing metabolic derangement into vascular injury. The present review critically addresses key pathophysiological aspects including (i) hyperglycemia, glycemic variability and insulin resistance as determinants and predictors of platelet activation, (ii) inflammatory mediators derived from platelets, such as soluble CD40 ligand, soluble CD36, Dickkopf-1 and probably soluble receptor for advanced glycation-end-products (sRAGE), which expand the functional repertoire of platelets from players of hemostasis and thrombosis to powerful amplifiers of inflammation by promoting the release of cytokines and chemokines, cell activation, and cell-cell interactions; (iii) molecular mechanisms underpinning the less-than-expected antithrombotic protection by aspirin (ASA), despite regular antiplatelet prophylaxis at the standard dosing regimen, and (iv) stratification of patients deserving different antiplatelet strategies, based on the metabolic phenotype. Taken together, these pathophysiological aspects may contribute to the development of promising mechanism-based therapeutic strategies to reduce the progression of atherothrombosis in diabetic subjects.

Diabetic autonomic neuropathy (DAN) is a serious and common complication of diabetes. Despite its relationship to an increased risk of cardiovascular mortality and its association with multiple symptoms and impairments, the significance of DAN has not been fully appreciated. The reported prevalence of DAN varies widely depending on the cohort studied and the methods of assessment. In randomly selected cohorts of asymptomatic individuals with diabetes, approximately 20% had abnormal cardiovascular autonomic function. DAN frequently coexists with other peripheral neuropathies and other diabetic complications, but DAN may be isolated, frequently preceding the detection of other complications. Major clinical manifestations of DAN include resting tachycardia, exercise intolerance, orthostatic hypotension, constipation, gastroparesis, erectile dysfunction, sudomotor dysfunction, impaired neurovascular function, "brittle diabetes," and hypoglycemic autonomic failure. DAN may affect many organ systems throughout the body (e.g., gastrointestinal [GI], genitourinary, and cardiovascular). GI disturbances (e.g., esophageal enteropathy, gastroparesis, constipation, diarrhea, and fecal incontinence) are common, and any section of the GI tract may be affected. Gastroparesis should be suspected in individuals with erratic glucose control. Upper-GI symptoms should lead to consideration of all possible causes, including autonomic dysfunction. Whereas a radiographic gastric emptying study can definitively establish the diagnosis of gastroparesis, a reasonable approach is to exclude autonomic dysfunction and other known causes of these upper-GI symptoms. Constipation is the most common lower-GI symptom but can alternate with episodes of diarrhea. Diagnostic approaches should rule out autonomic dysfunction and the well-known causes such as neoplasia. Occasionally, anorectal manometry and other specialized tests typically performed by the gastroenterologist may be helpful. DAN is also
Background A 2.5-month diabetes education training for community health workers (CHWs) was developed, implemented, and evaluated. Methods Training methods used included case studies, role-playing, and lectures. Exams were used throughout the training for its evaluation. Teaching was delivered by different ways: a one day American Diabetes Association (ADA) course; a five day Diabetes Self-Management Program (DSMP); Conversation Maps; and a series of seven National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) diabetes education booklets. Results Qualitative and quantitative evaluative methods were used during and after the training. The CHWs’ diabetes knowledge was evaluated by a pre- and post-test Diabetes Knowledge Questionnaire (DKQ). The post-test was conducted one week after completing the training. The findings showed that the diabetes knowledge of the CHWs increased. Conclusions Diabetes competencies and evaluative tools need to be developed specific for CHWs as a way to standardize all CHW diabetes trainings. PMID:27110434

Obesity and Type 2 Diabetes are nowadays summarized as "diabesity". That is due to the fact that obesity is frequently preceding and the most important risk factor in the increase of Type 2 Diabetes. The body mass index (BMI) is a crude measure of body fatness. Even normal weight persons can have lack in muscles (sarcopenia), which leads to the recommendation to measure waist und body fatness (e.g. BIA). Lifestyle management including nutrition and physical activity are important for diabetes prevention. In the therapy of Type 2 Diabetes body weight is increasingly used as secondary target. Also the choice of the anti-diabetic medication and concomitant medications is increasingly influenced by body weight. The significance of anti-obesity medications in the therapy of type 2 diabetes will have to be clarified by future studies. Bariatric surgery is at present indicated with a BMI above BMI > 35 kg/m(2) and can lead at least to partial diabetes remission but has to be part of a lifelong care concept.

Although majority of diabetes in children is type1 diabetes, childhood type2 diabetes prevalence is rapidly increasing due to changing lifestyle. Most patients can be definitely grouped into either of the two but some present diagnostic difficulty due to overlapping and non specific clinical features and laboratory findings. MODY and several other diseases affecting the pancreas also result in childhood diabetes. Treatment of diabetes in children presents unique challenges and primary prevention is of prime importance.

There are more than 29 million people in the United States with diabetes; it is estimated that by 2050, one in 3 individuals will have the disease. At least 50% of patients with diabetes are expected to undergo surgery in their lifetime. Complications from uncontrolled diabetes can impact multiple organ systems and affect perioperative risk. In this review, the authors discuss principles in diabetes management that will assist the perioperative clinician in caring for patients with diabetes.

Diabetic foot (DF) is the most common chronic complication, which depends mostly on the duration and successful treatment of diabetes mellitus. Based on epidemiological studies, it is estimated that 25% of persons with diabetes mellitus (PwDM) will develop the problems with DF during lifetime, while 5% do 15% will be treated for foot or leg amputation. The treatment is prolonged and expensive, while the results are uncertain. The changes in DF are influenced by different factors usually connected with the duration and regulation of diabetes mellitus. The first problems with DF are the result of misbalance between nutritional, defensive and reparatory mechanisms on the one hand and the intensity of damaging factors against DF on the other hand. Diabetes mellitus is a state of chronic hyperglycemia, consisting of changes in carbohydrate, protein and fat metabolism. As a consequence of the long duration of diabetes mellitus, late complications can develop. Foot is in its structure very complex, combined with many large and small bones connected with ligaments, directed by many small and large muscles, interconnected with many small and large blood vessels and nerves. Every of these structures can be changed by nutritional, defensive and reparatory mechanisms with consequential DE Primary prevention of DF includes all measures involved in appropriate maintenance of nutrition, defense and reparatory mechanisms.First, it is necessary to identify the high-risk population for DF, in particular for macrovascular, microvascular and neural complications. The high-risk population of PwDM should be identified during regular examination and appropriate education should be performed. In this group, it is necessary to include more frequent and intensified empowerment for lifestyle changes, appropriate diet, regular exercise (including frequent breaks for short exercise during sedentary work), regular self control of body weight, quit smoking, and appropriate treatment of glycemia

Pancreatic β cells contain the highest amount of zinc among cells within the human body, and hence, the relationship between zinc and diabetes has been a topic of great interest. While many studies demonstrating possible involvement of zinc deficiency in diabetes have been reported, precise mechanisms how zinc regulates glucose metabolism are still far from understood. Recent studies revealed that zinc can transmit signals that are driven by a variety of zinc transporters in a tissue and cell-type specific manner and deficiency in some zinc transporters may cause human diseases. Here, we review the role of zinc in metabolism particularly focusing on the emerging role of zinc transporters in diabetes.

Accumulating evidence suggests that low-carbohydrate, high-fat diets are safe and effective to reduce glycemia in diabetic patients without producing significant cardiovascular risks. Most of these studies have been carried out specifically restricting carbohydrates, which tends to lead to increased protein intake, thus reducing the ketosis. However, diets that limit protein as well as carbohydrates, entailing a composition very high in fat, appear even more effective to reduce glucose and whole-body glucose metabolism in humans. In animal models, low-carbohydrate, high-protein diets do not produce ketosis or reduce glycemia but rather cause obesity. However, limiting both protein and carbohydrates as in a classic ketogenic diet remarkably reduces blood glucose in animal models of type 1 and type 2 diabetes and reverses diabetic nephropathy. Future studies should assess if ketogenic diets would be effective to reverse diabetic complications in humans.

Abstract We investigated the factors that might influence the development of diabetic foot ulcers (DFUs) in type 2 diabetes patients without diabetic polyneuropathy (DPN). From January 2000 to December 2005, a total of 595 patients who had type 2 diabetes without DPN between the ages of 25 and 75 years, and had no prior history of DFUs were consecutively enrolled in the study. A cardiovascular autonomic function test was performed to diagnose cardiovascular autonomic neuropathy (CAN) using heart rate variability parameters. The median follow-up time was 13.3 years. Among the 449 (75.4%) patients who completed the follow-up evaluation, 22 (4.9%) patients developed new ulcers, and 6 (1.3%) patients underwent the procedure for lower extremity amputations. The patients in the DFUs group had a longer duration of diabetes, higher baseline HbA1c levels, higher rates of nephropathy, and CAN. A Cox hazard regression analysis results revealed that the development of DFUs was significantly associated with the presence of CAN (normal vs definite CAN; HR, 4.45; 95% confidence interval, 1.29–15.33) after adjusting for possible confounding factors. The development of DFUs was independently associated with CAN in patients with type 2 diabetes without DPN. We suggested the importance of CAN as a predictor of DFUs even in the patients without DPN, and the need to pay attention to patients with definite CAN and type 2 diabetes. PMID:27015188
In recent decades, diabetes care has undergone fundamental changes that have influenced the manner in which any type of diabetic patients are managed: (i) acceptance of tight metabolic control; (ii) recognition of primary care management; (iii) focus on quality improvement: and (iv) emphasis on cost containment. Then, the role of a diabetes care team has been recognized and acted upon to a far greater extent than before. Treatment of diabetes consists of two principal components: metabolic control and intervention to prevent complications. The former is a part of the primary health care scheme in which the indication for education, as well as care and treatment, frequently depend of the data produced by patients; the latter pertaining to hospital-based care. In 2001 in Japan, the number of the diabetes specialists is about 2500, and the certified diabetes educators certified are about 4300. However, the accessibility of the patients to the specialists still remains poor. Nurses, dietitians, medical technologists, pharmacists and physical therapists are eligible to take the examination of certified diabetes educator. They must be skilled at identifying the background of patients to improve care and health through life-style modification. Education for care and treatment consists of medical and educational models. In both of these, here are specific processes of diagnosis and therapy: along with medical diagnosis and treatment, through physical and laboratory examinations, assessment of the patient for indication of a curriculum by test of knowledge, skill and attitude for adequate educational therapy is necessary.

Diabetes mellitus is a metabolic disorder that is characterized by high blood glucose level, and body cannot produce enough insulin, or does not respond to the produced insulin. In spite of the diabetes education campaigns and programmes, a large number of people in the United Kingdom are living with diabetes. The main objective of the study is to evaluate the role of knowledge and awareness of diabetes in fighting against diabetes and to interpret to which extent is diabetes education successful. The systematic review to be carried out will include literature from 2001 to 2011 in the United Kingdom regarding awareness of diabetes among UK population and effectiveness of diabetes education. Literature will be accessed using search database, British medical journals, and library. Good quality papers will be used for the systematic review. Previous studies about diabetes education will consulted and assessed. This study is going to summarize the efficacy of diabetes education campaigns and programmes which are promising to enhance the awareness The outcome of the review will be the guideline for the government, education centres, researchers, and campaigns to implement more diabetic education programmes and easily accessible diabetes services and education interventions to increase the awareness of risk factors and complications of diabetes to overcome the increasing epidemic of diabetes in the United Kingdom.

In recent years, type 2 diabetes mellitus has evolved as a rapidly increasing epidemic that parallels the increased prevalence of obesity and which markedly increases the risk of cardiovascular disease across the globe. While ischemic heart disease represents the major cause of death in diabetic subjects, diabetic cardiomyopathy (DC) summarizes adverse effects of diabetes mellitus on the heart that are independent of coronary artery disease (CAD) and hypertension. DC increases the risk of heart failure (HF) and may lead to both heart failure with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF). Numerous molecular mechanisms have been proposed to underlie DC that partially overlap with mechanisms believed to contribute to heart failure. Nevertheless, the existence of DC remains a topic of controversy, although the clinical relevance of DC is increasingly recognized by scientists and clinicians. In addition, relatively little attention has been attributed to the fact that both underlying mechanisms and clinical features of DC may be partially distinct in type 1 versus type 2 diabetes. In the following review, we will discuss clinical and preclinical literature on the existence of human DC in the context of the two different types of diabetes mellitus. PMID:27999359
Background Diabetes and its complications are among the present and future challenges of the Turkish health care system. The objective of this paper is to discuss the current situation of diabetes and its management in Turkey with special emphasis on the changing policy environment. Methods A literature review in databases such as PUBMED was performed from 2000 to 2011. This synthesis was complemented by grey literature, personal communication and contact with national and provincial health authorities and experts in diabetes from Turkey. Results The literature review and expert consultations indicated a growing policy emphasis on diabetes. Both the public and private sectors, non-governmental organizations have initiated policy papers to shape the outlook of diabetes care in the future. This is in line with the current dynamics of the healthcare system. Conclusions Diabetes care will be high on the agenda in future. Evidence based policy-making is the key to implement the policies adopted so far and a supportive environment is needed. PMID:23597065

Diabetic retinopathy (DR) and diabetic macular edema (DME) are leading causes of blindness in the working-aged population of most developed countries. The increasing number of persons with diabetes worldwide suggests that DR/DME will continue to be major contributors to vision loss and associated functional impairment for years to come. Early detection of retinopathy in persons with diabetes is critical in preventing visual loss, but current methods of screening fail to identify a sizable number of high-risk patients. The control of diabetes-associated metabolic abnormalities (ie, hyperglycemia, hyperlipidemia, and hypertension) is also important in preserving visual function, as these conditions have been identified as risk factors for both the development and progression of DR/DME. The non-pharmacologic interventions for DR/DME, laser photocoagulation and vitrectomy, only target advanced stages of disease. Several biochemical mechanisms, including increased vascular endothelial growth factor production, protein kinase C beta activation, oxidative stress, and accumulation of intracellular sorbitol and advanced glycosylation end products, may contribute to the vascular disruptions that characterize DR/DME. The inhibition of these pathways holds the promise of the intervention for diabetic retinopathy with higher success rate and also at earlier, non-sight-threatening stages.

This study aims to estimate if diabetic women were more likely to experience postpartum depression symptoms than women without diabetes. This was a prospective cohort of women who received prenatal care at a hospital-affiliated prenatal clinic serving low-income women in Chicago, Illinois. For the primary analysis, women were divided by diabetes status (i.e., no diabetes or either gestational diabetes or pre-pregnancy diabetes). Postpartum depression was defined as a positive screen on the Patient Health Questionnaire-9. Rates of postpartum depression were compared, stratified by diabetic status. A multivariable logistic regression was performed to control for potential confounders. A planned secondary analysis compared women with pre-pregnancy diabetes to those without pre-pre-pregnancy diabetes. Three hundred and five women consented to participate of whom 100 (30.5 %) had gestational diabetes mellitus (GDM) and 33 (10.8 %) had pre-pregnancy diabetes. Compared to women without any diabetes, women with diabetes (either GDM or pre-pregnancy diabetes) had similar rates of antenatal [(OR) 0.69, 95 % CI) 0.44-1.08] and postpartum depression (OR 0.74, 95 % CI 0.33-1.66). However, postpartum depression was more common among women with pre-pregnancy diabetes (34.8 %) compared to non-diabetic women (16.7 %) (OR 2.67, 95 % CI 1.05-6.78). This association persisted even after adjusting for potential confounders (aOR 2.67, 95 % CI 1.05-9.79). Gestational diabetes was not associated with increased rates of depression. However, women with pre-pregnancy diabetes are more likely to experience postpartum depression compared to women without pre-pregnancy diabetes, even after adjusting for related comorbidities.
Obesity is a relatively new and serious world-wide epidemic. Obesity is a stronger predictor in mortality than either poverty or smoking, and obesity is also now more prevalent than malnutrition. The prevalence of obesity continues to increase, ironically, the rate of increase of obesity is highest amongst the morbidly obesity. Obesity is the result of many factors resulting in concert, including poor dietary habits, reduced physical activity and genetic predisposition. With the rapid increase in obesity there has been a pronounced increase in obesity-related metabolic disorders including type 2 diabetes, hyperlipidemia, hypertension and many others. These co-morbidities are responsible for more than 2.5 million deaths, worldwide. The loss of life expectancy due to obesity is profound. In comparison to a normal weight individual Caucasian, a 25-year-old morbidly obese man has a 22% reduction in the expected remaining life span, representing an approximate loss of 12 years of life.

Subclinical central diabetes insipidus (CDI) can be the outcome of a number of diseases that affect the hypothalamus-infundibulum-post hypophysis axis. One of the most common forms of subclinical CDI is linked to an autoimmune pathogenesis even if other causes may be also responsible. Among these, pregnancy, traumatic and surgical brain injury and some infiltrative, vascular, infectious and neoplastic diseases have been reported with increasing frequency. The natural history of autoimmune CDI seems to evolve through 4 functional stages according to the presence of antibodies to vasopressin-secreting cells (AVPcAb) and the relationship between their behavior overtime, the variations of posterior pituitary function and the characteristics of hypothalamic-hypophyseal region on magnetic resonance imaging. This staging is of crucial importance for the therapeutic strategy, taking into account that some stages could be still reversible. Several medical treatments have been suggested to interrupt the progression toward clinical CDI but the results are still discussed.

Diabetes insipidus (DI) is a rare complication of pregnancy. It is usually transient, being due to increased placental production of vasopressinase that inactivates circulating vasopressin. Gestational, transient DI occurs late in pregnancy and disappears few days after delivery. Acquired central DI can also occur during pregnancy, for example in a patient with hypophysitis or neuroinfundibulitis during late pregnancy or postpartum. Finally, pre-existing central or nephrogenic DI may occasionally be unmasked by pregnancy. Treatment with dDAVP (desmopressin, Minirin(®)) is very effective on transient DI of pregnancy and also on pre-existing or acquired central DI. Contrary to vasopressin, dDAVP is not degraded by vasopressinase. Nephrogenic DI is insensitive to dDAVP and is therefore more difficult to treat during pregnancy if fluid intake needs to be restricted.

Gestational diabetes mellitus (GDM) is the most common medical complication of pregnancy. It is associated with maternal and neonatal adverse outcomes. Maintaining adequate blood glucose levels in GDM reduces morbidity for both mother and baby. There is a lack of uniform strategies for screening and diagnosing GDM globally. This review covers the latest update in the diagnosis and management of GDM. The initial treatment of GDM consists of diet and exercise. If these measures fail to achieve glycemic goals, insulin should be initiated. Insulin analogs are more physiological than human insulin, and are associated with less risk of hypoglycemia, and may provide better glycemic control. Insulin lispro, aspart, and detemir are approved to be used in pregnancy. Insulin glargine is not approved in pregnancy, but the existing studies did not show any contraindications. The use of oral hypoglycemic agents; glyburide and metformin seems to be safe and effective in pregnancy. PMID:25828275

This article describes the primary health care offered to 8118 service users with diabetes in Brazil based on data from the PMAQ (Program to Improve Primary Care Access and Quality) first survey. Structure, access, service organization and management, and clinical care quality were analyzed. Prevalence of self-reported receipt of appropriate treatment was 14.3% (95% confidence interval [CI]: 13.4-15.2). Following adjustment, it was 26% higher (prevalence ratio [PR] = 1.26; 95% CI: 1.04-1.54) when primary health care centers had all the structure items investigated, it was 13% higher (PR = 1.13; 95% CI: 1.00-1.29) when the teams' work process for service organization and management was adequate and it was 14% higher (PR = 1.14; 95% CI: 1.00-1.30) when the teams' clinical practice was adequate.

Patients with diabetes mellitus are believed to be suspected to be immunocompromized hosts. Many reports have pointed out that diabetic patients are susceptible to certain infections such as surgical site infections, malignant otitis externa, mucormycosis, and necrotizing fasciitis. But their etiology seems to be non-uniform, heterogenous and individualized. Above all, obesity-related infections are also increasing accompanied with the recent rising incidence of obesity. Further studies should be addressed about the relationships between infections and diabetes which include the factors of body mass index, life style, degree of diabetes complications, and poor glycemic control duration. They could live a normal life the same as healthy subjects if good glycemic control is achieved without hypoglycemia.
Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

Gestational diabetes mellitus (GDM) is increasing in prevalence in tandem with the dramatic increase in the prevalence of overweight and obesity in women of childbearing age. Much controversy surrounds the diagnosis and management of gestational diabetes, emphasizing the importance and relevance of clarity and consensus. If newly proposed criteria are adopted universally a significantly growing number of women will be diagnosed as having GDM, implying new therapeutic challenges to avoid foetal and maternal complications related to the hyperglycemia of gestational diabetes. This review provides an overview of clinical issues related to GDM, including the challenges of screening and diagnosis, the pathophysiology behind GDM, the treatment and prevention of GDM and the long and short term consequences of gestational diabetes for both mother and offspring.

Diabetes mellitus is a devastating disease and the World Health Organization (WHO) expects that the number of diabetic patients will increase to 300 million by the year 2025. Patients with diabetes experience decreased insulin secretion that is linked to a significant reduction in the number of islet cells. Type 1 diabetes is characterized by the selective destruction of pancreatic β cells caused by an autoimmune attack. Type 2 diabetes is a more complex pathology that, in addition to β cell loss caused by apoptotic programs, includes β cell de-differentiation and peripheric insulin resistance. The success achieved over the last few years with islet transplantation suggests that diabetes can be cured by the replenishment of deficient β cells. These observations are proof of the concept and have intensified interest in treating diabetes or other diseases not only by cell transplantation but also by stem cells. An increasing body of evidence indicates that, in addition to embryonic stem cells, several potential adult stem/progenitor cells derived from the pancreas, liver, spleen, and bone marrow could differentiate into insulin-producing cells in vitro or in vivo. However, significant controversy currently exists in this field. Pharmacological approaches aimed at stimulating the in vivo/ex vivo regeneration of β cells have been proposed as a way of augmenting islet cell mass. Overexpression of embryonic transcription factors in stem cells could efficiently induce their differentiation into insulin-expressing cells. A new technology, known as protein transduction, facilitates the differentiation of stem cells into insulin-producing cells. Recent progress in the search for new sources of β cells has opened up several possibilities for the development of new treatments for diabetes.

Diabetic nephropathy is a leading cause of end-stage renal failure worldwide. Its morphologic characteristics include glomerular hypertrophy, basement membrane thickening, mesangial expansion, tubular atrophy, interstitial fibrosis and arteriolar thickening. All of these are part and parcel of microvascular complications of diabetes. A large body of evidence indicates that oxidative stress is the common denominator link for the major pathways involved in the development and progression of diabetic micro- as well as macrovascular complications of diabetes. There are a number of macromolecules that have been implicated for increased generation of reactive oxygen species (ROS), such as, NAD(P)H oxidase, advanced glycation end products (AGE), defects in polyol pathway, uncoupled nitric oxide synthase (NOS) and mitochondrial respiratory chain via oxidative phosphorylation. Excess amounts of ROS modulate activation of protein kinase C, mitogen-activated protein kinases, and various cytokines and transcription factors which eventually cause increased expression of extracellular matrix (ECM) genes with progression to fibrosis and end stage renal disease. Activation of renin-angiotensin system (RAS) further worsens the renal injury induced by ROS in diabetic nephropathy. Buffering the generation of ROS may sound a promising therapeutic to ameliorate renal damage from diabetic nephropathy, however, various studies have demonstrated minimal reno-protection by these agents. Interruption in the RAS has yielded much better results in terms of reno-protection and progression of diabetic nephropathy. In this review various aspects of oxidative stress coupled with the damage induced by RAS are discussed with the anticipation to yield an impetus for designing new generation of specific antioxidants that are potentially more effective to reduce reno-vascular complications of diabetes.

Background: Diabetes mellitus affects individuals of all ages and socioeconomic status. Skin is affected by the acute metabolic derangements as well as by chronic degenerative complications of diabetes. Aims: To evaluate the prevalence of skin manifestations in patients with diabetes mellitus. To analyze the prevalence and pattern of skin disorders among diabetic patients from this region of Western Himalayas. Materials and Methods: One hundred consecutive patients with the diagnosis of diabetes mellitus and having skin lesions, either attending the diabetic clinic or admitted in medical wards were included in this study. Results: The common skin disorders were: Xerosis (44%), diabetic dermopathy (36%), skin tags (32%), cutaneous infections (31%), and seborrheic keratosis (30%). Conclusion: Skin is involved in diabetes quite often and the manifestations are numerous. High prevalence of xerosis in our diabetic population is perhaps due to cold and dry climatic conditions in the region for most of the time in the year. PMID:20418975
Populations are aging and the prevalence of diabetes mellitus is increasing tremendously. The number of older people with diabetes is increasing unexpectedly. Aging and diabetes are both risk factors for functional disability. Thus, increasing numbers of frail or disabled older patients with diabetes will increase both direct and indirect health-related costs. Diabetes has been reported as an important risk factor of developing physical disability in older adults. Older people with diabetes have lower muscle mass and weaker muscle strength. In addition, muscle quality is poorer in diabetic patients. Sarcopenia and frailty have a common soil and may share a similar pathway for multiple pathologic processes in older people. Sarcopenia is thought to be an intermediate step in the development of frailty in patients with diabetes. Thus, early detection of sarcopenia and frailty in older adults with diabetes should be routine clinical practice to prevent frailty or to intervene earlier in frail patients. PMID:27098509

Diabetic nephropathy is a leading cause of end-stage renal failure all over the world. Advanced human diabetic nephropathy is characterized by the presence of specific lesions including nodular lesions, doughnut lesions, and exudative lesions. Thus far, animal models precisely mimicking advanced human diabetic nephropathy, especially nodular lesions, remain to be fully established. Animal models with spontaneous diabetic kidney diseases or with inducible kidney lesions may be useful for investigating the pathogenesis of diabetic nephropathy. Based on pathological features, we previously reported that diabetic glomerular nodular-like lesions were formed during the reconstruction process of mesangiolysis. Recently, we established nodular-like lesions resembling those seen in advanced human diabetic nephropathy through vascular endothelial injury and mesangiolysis by administration of monocrotaline. Here, in this review, we discuss diabetic nodular lesions and its animal models resembling human diabetic kidney lesions, with our hypothesis that endothelial cell injury and mesangiolysis might be required for nodular lesions.

Adhesion molecules play a significant role in leukocyte migration across the endothelium and are also involved in regulating immune system. It is shown that diabetic patients have an increase of soluble adhesion molecules (sICAM-1, sICAM-2, sVCAM-1, sE-selectin, sL-selectin, sP-selectin) considered an integral part of inflammatory state. This inflammation is responsible for the increased cardiovascular risk of these patients. There is a close link between hyperglycemia, oxidative stress, coagulopathy and inflammation and between these factors and the vascular damage. Various studies have showed the potential role of adhesion molecules in the pathogenesis of diabetic vasculopathy. They promote leukocyte recruitment, which is one of the initial steps in the genesis of atherosclerotic plaque. Adhesion molecules are also involved in the pathogenesis of diabetes mellitus type 1; sICAM-1 would have a particular immunomodulatory role in the process of destroying beta-cells and could be used as a subclinical marker of insulitis. Plasma levels of soluble adhesion molecules correlate with hyperglycemia, insulin resistance, dyslipidemia and obesity; they are associated with the development of nephropathy, retinopathy, myocardial infarction, stroke and obliterant peripheral arterial disease in diabetic type 1 and 2. Given the role of these molecules in endothelial dysfunction genesis and tissue damage associated with diabetes, they could constitute a therapeutic target for the prevention of genesis and progression of chronic complications of diabetic disease.
Diabetes and its complications impose significant economic consequences on individuals, families, health systems, and countries. The control of diabetes is an interdisciplinary endeavor, which includes significant components of modeling, signal processing and control. Models: first, I will discuss the minimal (coarse) models which describe the key components of the system functionality and are capable of measuring crucial processes of glucose metabolism and insulin control in health and diabetes; then, the maximal (fine-grain) models which include comprehensively all available knowledge about system functionality and are capable to simulate the glucose-insulin system in diabetes, thus making it possible to create simulation scenarios whereby cost effective experiments can be conducted in silico to assess the efficacy of various treatment strategies - in particular I will focus on the first in silico simulation model accepted by FDA as a substitute to animal trials in the quest for optimal diabetes control. Signals: I will review metabolic monitoring, with a particular emphasis on the new continuous glucose sensors, on the crucial role of models to enhance the interpretation of their time-series signals, and on the opportunities that they present for automation of diabetes control. Control: I will review control strategies that have been successfully employed in vivo or in silico, presenting a promise for the development of a future artificial pancreas and, in particular, I will discuss a modular architecture for building closed-loop control systems, including insulin delivery and patient safety supervision layers.

Diabetic retinopathy remains one of the most debilitating chronic complications, but despite extensive research in the field, the exact mechanism(s) responsible for how retina is damaged in diabetes remains ambiguous. Many metabolic pathways have been implicated in its development, and genes associated with these pathways are altered. Diabetic environment also facilitates epigenetics modifications, which can alter the gene expression without permanent changes in DNA sequence. The role of epigenetics in diabetic retinopathy is now an emerging area, and recent work has shown that genes encoding mitochondrial superoxide dismutase (Sod2) and matrix metalloproteinase-9 (MMP-9) are epigenetically modified, activates of epigenetic modification enzymes, histone lysine demethylase 1 (LSD1), and DNA methyltransferase are increased, and the micro RNAs responsible for regulating nuclear transcriptional factor and VEGF are upregulated. With the growing evidence of epigenetic modifications in diabetic retinopathy, better understanding of these modifications has potential to identify novel targets to inhibit this devastating disease. Fortunately, the inhibitors and mimics targeted towards histone modification, DNA methylation, and miRNAs are now being tried for cancer and other chronic diseases, and better understanding of the role of epigenetics in diabetic retinopathy will open the door for their possible use in combating this blinding disease.

Although pathologic classifications exist for several renal diseases, including IgA nephropathy, focal segmental glomerulosclerosis, and lupus nephritis, a uniform classification for diabetic nephropathy is lacking. Our aim, commissioned by the Research Committee of the Renal Pathology Society, was to develop a consensus classification combining type1 and type 2 diabetic nephropathies. Such a classification should discriminate lesions by various degrees of severity that would be easy to use internationally in clinical practice. We divide diabetic nephropathy into four hierarchical glomerular lesions with a separate evaluation for degrees of interstitial and vascular involvement. Biopsies diagnosed as diabetic nephropathy are classified as follows: Class I, glomerular basement membrane thickening: isolated glomerular basement membrane thickening and only mild, nonspecific changes by light microscopy that do not meet the criteria of classes II through IV. Class II, mesangial expansion, mild (IIa) or severe (IIb): glomeruli classified as mild or severe mesangial expansion but without nodular sclerosis (Kimmelstiel-Wilson lesions) or global glomerulosclerosis in more than 50% of glomeruli. Class III, nodular sclerosis (Kimmelstiel-Wilson lesions): at least one glomerulus with nodular increase in mesangial matrix (Kimmelstiel-Wilson) without changes described in class IV. Class IV, advanced diabetic glomerulosclerosis: more than 50% global glomerulosclerosis with other clinical or pathologic evidence that sclerosis is attributable to diabetic nephropathy. A good interobserver reproducibility for the four classes of DN was shown (intraclass correlation coefficient = 0.84) in a test of this classification.

Diabetic nephropathy (DN) is a leading cause of mortality and morbidity in patients with diabetes. This complication reflects a complex pathophysiology, whereby various genetic and environmental factors determine susceptibility and progression to end-stage renal disease. DN should be considered in patients with type 1 diabetes for at least 10 years who have microalbuminuria and diabetic retinopathy, as well as in patients with type 1 or type 2 diabetes with macroalbuminuria in whom other causes for proteinuria are absent. DN may also present as a falling estimated glomerular filtration rate with albuminuria as a minor presenting feature, especially in patients taking renin–angiotensin–aldosterone system inhibitors (RAASi). The pathological characteristic features of disease are three major lesions: diffuse mesangial expansion, diffuse thickened glomerular basement membrane, and hyalinosis of arterioles. Functionally, however, the pathophysiology is reflected in dysfunction of the mesangium, the glomerular capillary wall, the tubulointerstitium, and the vasculature. For all diabetic patients, a comprehensive approach to management including glycemic and hypertensive control with RAASi combined with lipid control, dietary salt restriction, lowering of protein intake, increased physical activity, weight reduction, and smoking cessation can reduce the rate of progression of nephropathy and minimize the risk for cardiovascular events. This review focuses on the latest published data dealing with the mechanisms, diagnosis, and current treatment of DN. PMID:26894033

The natural history of diabetic nephropathy offered an average survival of only 5-7 years. During the past decades, multiple changes in therapy and lifestyle have occurred. The prognosis of diabetic nephropathy after implementing stricter control of blood pressure (including increased use of long-term renin-angiotensin system inhibition), lipids, and glycemia, along with less smoking and other lifestyle and treatment advancements, is inadequately analyzed. To clarify this, we studied 497 patients with type 1 diabetes and diabetic nephropathy at the Steno Diabetes Center and compared them with previous data, obtained using identical criteria at our hospital. The glomerular filtration rate, measured yearly by 51Cr-EDTA plasma clearance, was a mean of 71 ml/min per 1.73 m2 at baseline. The mean glomerular filtration rate decline was significantly reduced by 19% (95% confidence interval 5-34) from previously 4.0 to 3.3 ml/min per 1.73 m2/year. During a median follow-up of 9.1 years, 29% of participants doubled their plasma creatinine or developed end-stage renal disease. Mortality risk was similar to our prior study (hazard ratio 1.05 (0.76-1.43). However, after age adjustment, as both diabetes and nephropathy onset occurred later in life, mortality was reduced by 30%. Risk factors for decline in glomerular filtration rate, death, and other renal end points were generally in agreement with prior studies. Thus, with current treatment of nephropathy in type 1 diabetes, the prognosis and loss of renal function has improved along with better control of modifiable risk factors.
Diabetes mellitus comprises of a group of heterogeneous disorders, which have an increase in blood glucose concentrations in common. The current classifications for diabetes mellitus type 1-4 are described and the main features of type 1 and type 2 diabetes are compared to allow for better discrimination between these diabetes types. Furthermore, the criteria for the correct biochemical diagnosis during fasting and oral glucose tolerance tests as well as the use of hemoglobin A1c (HbA1c) are summarized. These data form the basis of the recommendations of the Austrian Diabetes Association for the clinical praxis of diabetes treatment.

Background The impact of diabetes mellitus in patients with multiple system injuries remains obscure. This study was designed to increase knowledge of outcomes of polytrauma in patients who have diabetes mellitus. Methods Data from the Trauma Audit and Research Network was used to identify patients who had suffered polytrauma during 2003 to 2011. These patients were filtered to those with known outcomes, then separated into those with diabetes, those known to have other co-morbidities but not diabetes and those known not to have any co-morbidities or diabetes. The data were analyzed to establish if patients with diabetes had differing outcomes associated with their diabetes versus the other groups. Results In total, 222 patients had diabetes, 2,558 had no past medical co-morbidities (PMC), 2,709 had PMC but no diabetes. The diabetic group of patients was found to be older than the other groups (P <0.05). A higher mortality rate was found in the diabetic group compared to the non-PMC group (32.4% versus 12.9%), P <0.05). Rates of many complications including renal failure, myocardial infarction, acute respiratory distress syndrome, pulmonary embolism and deep vein thrombosis were all found to be higher in the diabetic group. Conclusions Close monitoring of diabetic patients may result in improved outcomes. Tighter glycemic control and earlier intervention for complications may reduce mortality and morbidity.

We examined the bone mineral density (BMD) of the proximal region and the mid-diaphysis of the femur using dual energy X-ray absorption (DXA), the blood osteocalcin level and the blood glucose level every five weeks from 8 to 23 weeks old in KK-Ay diabetic mice. The BMD of the proximal region after 18 weeks old was significantly lower when compared with that at 8 weeks old (p<0.05), whereas there was no significant difference in the BMD of the mid-diaphysis at each week. The BMD of the proximal region at 18 weeks old was significantly lower than that in ddY mice, used as controls (p<0.05). The blood osteocalcin level at 18 weeks old was significantly lower than that at 8 weeks old and that in 18-week-old ddY mice (p<0.05). There was significant negative correlation between the blood glucose level and the BMD of the proximal region (r=-0.64, p<0.05). These results suggest that type 2 diabetes exerts an influence only on spongy bone, not on cortical bone, and that the BMD in the proximal region of the femur seems to be affected by blood glucose level, parallel with the progression of diabetes, through the blood osteocalcin level. In the present study, we show the characteristics of diabetic osteopenia in KK-Ay mice, an animal model of type 2 diabetes.

OBJECTIVE--To develop a simple, economically viable, and effective means of population screening for diabetes mellitus. DESIGN--A postal request system for self testing for glycosuria with foil wrapped dipsticks. Preprandial and postprandial tests were compared with a single postprandial test. The subjects were instructed how to test, and a result card was supplied on which to record and return the result. All those recording a positive test result and 50 people recording a negative result were invited for an oral glucose tolerance test. SETTING--General practice in east Suffolk, list size 11534. PATIENTS--All subjects aged 45-70 years registered with the practice were identified by Suffolk Family Health Services Authority (n = 3057). The 73 subjects known to have diabetes from the practice's register were excluded, leaving 2984 subjects, 2363 (79.2%) of whom responded. 1167 subjects completed the single test and 1196 the two tests. MAIN OUTCOME MEASURES--Response rate and number of patients with glycosuria. Sensitivity, specificity, and positive predictive value of a single postprandial test and preprandial and postprandial tests. Number of new cases of diabetes identified and cost of screening. RESULTS--Of the patients completing the single postprandial test, 29 had a positive result, an oral glucose tolerance test showed that eight (28%) had diabetes, six (21%) impaired glucose tolerance, and 14 (48%) normal glucose tolerance. 44 of the group who tested before and after eating had a positive result; nine (20%) had diabetes, five (11%) impaired tolerance, and 26 (11%) normal tolerance. Screening cost 59p per subject and 81 pounds per case detected. Of the 17 people with previously undiagnosed diabetes, eight were asymptomatic and 11 had not visited their general practitioner in the past three months. CONCLUSIONS--A postal request system for self testing for postprandial glycosuria in people aged 45-70 is a simple and effective method of population screening for

Infection plays a pivotal role in enhancing a diabetic foot at risk toward amputation. Effective antibiotic therapy against the offending pathogens is an important component of treatment of diabetic foot infections. Recognition of the pathogen is always difficult as the representative deep tissue sample for culture is surrounded by ulcer surface harbouring colonies of organisms frequently labelled as skin commensals. The emergent of resistant strains represents a compounding problem standing against efforts to prevent amputation. This study was undertaken to identify the pathogens associated with diabetic foot infection in terms of their frequency and sensitivity against certain commonly used antibiotics. Forty-four consecutive patients with open diabetic foot infections had wound swab taken for culture and sensitivity testing. Cultures positive were observed in 89% of the cases with Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeroginosa encountered in 20%, 14% and 14% of cases respectively. Mixed growths were isolated in 6% of cultures. All Staphylcoccus aureus isolates were resistant to Penicillin but 80% were sensitive to Erythromycin and Co-trimoxazole. Klebsiella pneumoniae isolates were sensitive to Methicillin and Gentamycin in 80% and 60% of cases respectively, and resistant to Ampicillin and Ceftazidime in 83% and 50% respectively. All Pseudomonas aeroginosa isolates were sensitive to Amikacin and Ciprofloxacin but 50% were resistant to Gentamycin. There was no single antibiotic possessing good coverage for all common organisms isolated from diabetic foot lesions. Staphylococcus aureus remains the predominant cause of diabetic foot infections followed by Klebsiela pneumonia and Pseudomonas aeroginosa. Most infections are monomicrobial. The emergence of multiresistant organisms is a worrying feature in diabetic foot infections.

Diuretic antihypertensive therapy is recommended as first choice by many guidelines, often in combination with beta-blockers. However, such recommendations are based on relatively short-term trials, whereas treatment for hypertension is often a lifetime process. A meta-analysis of seven studies in 58,010 individuals, showed that the 'new' therapies, namely angiotensin-converting enzyme (ACE) inhibitors, angiotensin II type 1 receptor blockers (ARBs) and calcium channel blockers (CCBs) provoke less new diabetes than the conventional 'old' therapies (diuretics and beta-blockers). ACE inhibitors/ARBs decreased new diabetes by 20% (P < 0.001), whereas CCBs decreased new diabetes by 16% (P < 0.001). The number needed to treat for approximately 4 years by new rather than old conventional therapy to avoid one case of new diabetes is about 60-70. Other factors contributing to increased coronary risk are increased metabolic syndrome, blood lipid changes and hypokalaemia. It is not certain whether it is the new therapy that provides protection against new diabetes or the conventional therapy that precipitates new diabetes. However, when compared with placebo, ACE inhibition by ramipril or by the ARB, candesartan, both decrease the incidence of new diabetes, raising the hypothesis that these agents actually prevent the changes leading to insulin resistance, possibly by lessening the adverse effects of angiotensin II on the endothelium. Conversely, lipid abnormalities with conventional treatment could exert adverse effects on the endothelium. Therefore endothelial changes could help to explain the benefits of 'modern' treatment compared with the defects of conventional therapy.
The prevalence and impact of type 2 diabetes are reaching epidemic proportions in the United States. Data suggest that effective management can reduce the risk for both microvascular and macrovascular complications of diabetes. In treating patients with diabetes, physicians must be prepared not only to tailor the initial treatment to the individual and his or her disease severity but also to advance treatment as necessary and in step with disease progression. The majority of patients with diabetes are not at goal for glycated hemoglobin A1C, fasting plasma glucose, or postprandial plasma glucose levels. Although lifestyle changes based on improved diet and exercise practices are basic elements of therapy at every stage, pharmacologic therapy is usually necessary to achieve and maintain glycemic control. Oral antidiabetic agents may be effective early in the disease but, eventually, they are unable to compensate as the disease progresses. For patients unable to achieve glycemic control on 2 oral agents, current guidelines strongly urge clinicians to consider the initiation of insulin as opposed to adding a third oral agent. Recent research suggests that earlier initiation of insulin is more physiologic and may be more effective in preventing complications of diabetes. Newer, longer-lasting insulin analogs and the use of simplified treatment plans may overcome psychological resistance to insulin on the part of physicians and patients. This article summarizes the risks associated with uncontrolled fasting and postprandial hyperglycemia, briefly reviews the various treatment options currently available for type 2 diabetes, presents case vignettes to illustrate crossroads encountered when advancing treatment, and offers guidance to the osteopathic physician on the selection of appropriate treatments for the management of type 2 diabetes.

Periodontal disease (PD) is one of the most commonly known human chronic disorders. The relationship between PD and several systemic diseases such as diabetes mellitus (DM) has been increasingly recognized over the past decades. Objective: The purpose of this review is to provide the reader with knowledge concerning the relationship between PD and DM. Many articles have been published in the english and Portuguese literature over the last 50 years examining the relationship between these two chronic diseases. Data interpretation is often confounded by varying definitions of DM, PD and different clinical criteria were applied to determine the prevalence, extent and severity of PD, levels of glycemic control and diabetes-related complications. Methods: This paper provides a broad overview of the predominant findings from research conducted using the BBO (Bibliografia Brasileira de Odontologia), MEDLINE, LILACS and PubMed for Controlled Trials databases, in english and Portuguese languages published from 1960 to October 2012. Primary research reports on investigations of relationships between DM/DM control, PD/periodontal treatment and PD/DM/diabetes-related complications identified relevant papers and meta-analyses published in this period. Results: This paper describes the relationship between PD and DM and answers the following questions: 1- The effect of DM on PD, 2- The effects of glycemic control on PD and 3- The effects of PD on glycemic control and on diabetes-related complications. Conclusions: The scientific evidence reviewed supports diabetes having an adverse effect on periodontal health and PD having an adverse effect on glycemic control and on diabetes-related complications. Further research is needed to clarify these relationships and larger, prospective, controlled trials with ethnically diverse populations are warranted to establish that treating PD can positively influence glycemic control and possibly reduce the burden of diabetes

Nonenzymatic glycation of macromolecules in diabetes mellitus (DM) is accelerated due to persistent hyperglycemia. Reducing sugar such as glucose reacts non enzymatically with free €-amino groups of proteins through series of reactions forming Schiff bases. These bases are converted into Amadori product and further into AGEs. Non enzymatic glycation has the potential to alter the biological, structural and functional properties of macromolecules both in vitro and in vivo. Studies have suggested that amadori as well as AGEs are involved in the micro-macro vascular complications in DM, but most studies have focused on the role of AGEs in vascular complications of diabetes. Recently putative AGE-induced patho-physiology has shifted attention from the possible role of amadori-modified proteins, the predominant form of the glycated proteins in the development of the diabetic complications. Human serum albumin (HSA), the most abundant protein in circulation contains 59 lysine and 23 arginine residues that could, in theory be involved in glycation. Albumin has dual nature, first as a marker of intermediate glycation and second as a causative agent of the damage of tissues. Among the blood proteins, hemoglobin and albumin are the most common proteins that are glycated. HSA with a shorter half life than RBC, appears to be an alternative marker of glycemic control as it can indicate blood glucose status over a short period (2-3 weeks) and being unaffected by RBCs life span and variant haemoglobin, anemia etc which however, affect HbA1c. On the other hand, Amadori albumin may accumulate in the body tissues of the diabetic patients and participate in secondary complications. Amadori-albumin has potential role in diabetic glomerulosclerosis due to long term hyperglycaemia and plays an important role in the pathogenesis of diabetic nephropathy. This review is an approach to compile both the nature of glycated albumin as a damaging agent of tissues and as an intermediate

In Brief Limited diabetes numeracy may be an important factor affecting diabetes care and treatment adherence. This study assessed the relationship between the Diabetes Numeracy Test (DNT-15 score) and patient and treatment variables. Patients who had type 1 diabetes and those who received care from specialty centers had higher levels of numeracy, but this did not translate into improved glucose control. PMID:25646940

A better understanding of pathogenic mechanisms is required in order to treat diseases. However, the mechanisms of diabetes mellitus and diabetic complications are extremely complex. Immune reactions are involved in the pathogenesis of diabetes and its complications, while diabetes influences immune reactions. Furthermore, both diabetes and immune reactions are influenced by genetic and environmental factors. To address these issues, animal models are useful tools. So far, various animal models of diabetes have been developed in rats, which have advantages over mice models in terms of the larger volume of tissue samples and the variety of type 2 diabetes models. In this review, we introduce rat models of diabetes and summarize the immune reactions in diabetic rat models. Finally, we speculate on the relationship between immune reactions and diabetic episodes. For example, diabetes-prone Biobreeding rats, type 1 diabetes model rats, exhibit increased autoreactive cellular and inflammatory immune reactions, while Goto-Kakizaki rats, type 2 diabetes model rats, exhibit increased Th2 reactions and attenuation of phagocytic activity. Investigation of immunological abnormalities in various diabetic rat models is useful for elucidating complicated mechanisms in the pathophysiology of diabetes. Studying immunological alterations, such as predominance of Th1/17 or Th2 cells, humoral immunity, and innate immune reactions, may improve understanding the structure of amplification circuits for diabetes in future studies.

Erythropoietin (EPO) is a 30.4 kDa growth factor and cytokine that governs cell proliferation, immune modulation, metabolic homeostasis, vascular function, and cytoprotection. EPO is under investigation for the treatment of variety of diseases, but appears especially suited for the treatment of disorders of metabolism that include diabetes mellitus (DM). DM and the complications of this disease impact a significant portion of the global population leading to disability and death with currently limited therapeutic options. In addition to its utility for the treatment of anemia, EPO can improve cardiac function, reduce fatigue, and improve cognition in patients with DM as well as regulate cellular energy metabolism, obesity, tissue repair and regeneration, apoptosis, and autophagy in experimental models of DM. Yet, EPO can have adverse effects that involve the vasculature system and unchecked cellular proliferation. Critical to the cytoprotective capacity and the potential for a positive clinical outcome with EPO are the control of signal transduction pathways that include protein kinase B, the mechanistic target of rapamycin, Wnt signaling, mammalian forkhead transcription factors of the O class, silent mating type information regulation 2 homolog 1 (Saccharomyces cerevisiae), and AMP activated protein kinase. Therapeutic strategies that can specifically target and control EPO and its signaling pathways hold great promise for the development of new and effective clinical treatments for DM and the complications of this disorder.

Nephrogenic diabetes insipidus (NDI), which can be inherited or acquired, is characterized by an inability to concentrate urine despite normal or elevated plasma concentrations of the antidiuretic hormone arginine vasopressin (AVP). Polyuria, with hyposthenuria, and polydipsia are the cardinal clinical manifestations of the disease. About 90% of patients with congenital NDI are males with X-linked recessive NDI (OMIM 304800) who have mutations in the arginine-vasopressin receptor 2 (AVPR2) gene that codes for the vasopressin V2 receptor. In about 10% of the families studied, congenital NDI has an autosomal recessive or autosomal dominant mode of inheritance (OMIM 222000 and 125800). In these families, mutations have been identified in the aquaporin-2 gene (AQP2) (OMIM 107777), which codes for the vasopressin-sensitive water channel. Most missense AVPR2 mutations lead to receptors that are trapped intracellularly; a few mutant receptors reach the cell surface but are unable to bind AVP or to properly trigger an intracellular cyclic adenosine monophosphate signal. Similarly, most AQP2 mutant proteins are also misrouted. Prior knowledge of AVPR2 or AQP2 mutations in NDI families and perinatal mutation testing is of direct clinical value because early diagnosis and treatment can avert the physical and mental retardation associated with repeated episodes of dehydration.

ABSTRACT Central diabetes insipidus (CDI), characterized by polyuria and polydipsia, is caused by deficiency of arginine vasopressin (AVP), an antidiuretic hormone which acts on V2 receptors in kidney to promote reabsorption of free water. CDI is classified into three subtypes; idiopathic, secondary and familial. A previous study suggests that infundibulo-neurohypophysitis might be an underlying cause of idiopathic CDI. Among secondary CDI, the tumors in the central nervous system such as craniopharyngioma and germ cell tumors are the most frequent causes. Familial CDI is inherited mostly in an autosomal dominant mode, and the number of causal mutations in the AVP gene locus reported so far exceeds 80. CDI is treated with desmopressin, an analogue of vasopressin, and the tablet is preferred to the nasal form because it is easier to administer. It is also shown that the oral disintegrating tablet formula increases QOL and decreases the incidence of hyponatremia in CDI patients. In some CDI patients, the osmoreceptors in the hypothalamus do not function and patients do not sense thirst. These adipsic CDI patients are treated with desmopressin and adjusting the amount of daily water intake based on body weight measurement; but controlling the water balance is extremely difficult, and morbidity and mortality are shown to be high in these patients.

Nephrogenic diabetes insipidus is a rare hereditary disease, characterized by a resistance of the renal collecting duct to the action of the antidiuretic hormone, arginine vasopressin, responsible for the inability of the kidney to concentrate urine. More than 90% of the patients are males and have the X-linked recessive form of the disease usually presenting with polyuria and polydipsia in infancy. This mode of inheritance is related to mutations in the V(2) receptor gene, located in the Xq28 chromosomal region. Less than 10% of the patients have an autosomal-recessive or an autosomal-dominant mode of inheritance with clinical manifestations occurring in males and females, related to mutations in the aquaporin-2 gene, located in chromosome region 12q13. The aim of the treatment is to avoid chronic and acute dehydration episodes. It remains symptomatic, mainly based on an hypoosmotic diet and the use of hydrochlorothiazide and indomethacin. Recent findings showed that pharmacological chaperones, such as V(2) nonpeptide antagonists, are able to rescue some of the V(2) receptor mutants and could be useful tools for treatment in the future.

This review is focused on the materials and methods used to fabricate closed-loop systems for type 1 diabetes therapy. Herein, we give a brief overview of current methods used for patient care and discuss two types of possible treatments and the materials used for these therapies–(i) artificial pancreases, comprised of insulin producing cells embedded in a polymeric biomaterial, and (ii) totally synthetic pancreases formulated by integrating continuous glucose monitors with controlled insulin release through degradable polymers and glucose-responsive polymer systems. Both the artificial and the completely synthetic pancreas have two major design requirements: the device must be both biocompatible and be permeable to small molecules and proteins, such as insulin. Several polymers and fabrication methods of artificial pancreases are discussed: microencapsulation, conformal coatings, and planar sheets. We also review the two components of a completely synthetic pancreas. Several types of glucose sensing systems (including materials used for electrochemical, optical, and chemical sensing platforms) are discussed, in addition to various polymer-based release systems (including ethylene-vinyl acetate, polyanhydrides, and phenylboronic acid containing hydrogels).

Traditionally, diabetes education has relied on written materials, with limited resources available for children with diabetes. Mobile games can be effective and motivating tools for the promotion of children's health. In our earlier work, we proposed a novel approach for designing computer games aimed at educating children with diabetes. In this article, we apply our game design to a mobile Android game (Mario Brothers). We also introduce four heuristics that are specifically designed for evaluating the mobile game, by adapting traditional usability heuristics. Results of a pilot study (n = 12) to evaluate gameplay over 1-week showed that the children found the game engaging and improved their knowledge of healthy diet and lifestyle.

Diabetic retinopathy, an oculardisease, is governed by systemic as well as local ocular factors. These include primarily chronic levels of blood glucose. Individuals with chronically elevated blood glucose levels have substantially more, and more severe, retinopathy than those with lower blood glucose levels. The relationship of blood glucose to retinopathy is continuous, with no threshold although individuals with hemoglobin A1c levels (a measure of chronic glycemia) <6.5%, generally develop little or no retinopathy. Blood pressure levels have been claimed to influence retinopathy development and progression, but multiple controlled clinical trials of antihypertensive agents in diabetic subjects have produced only weak evidence of benefit from blood pressure lowering on the incidence and progression of diabetic retinopathy. Elevated blood lipids seem to play a role in the progression of retinopathy, and two trials of fenofibrate, a lipid-lowering agent that has not proved effective in preventing cardiovascular disease, have shown benefit in preventing retinopathy progression. The mechanism of this effect may not, however, be directly related to the reduction in blood lipids. Finally, there is strong, but only circumstantial, evidence for a genetic or epigenetic influence on the pathogenesis of diabetic retinopathy. Despite the power of large-scale epidemiologic studies and modern molecular biological and computational techniques, the gene or genes, which predispose or protect against the development and progression of diabetic retinopathy remain elusive.

Diabetes mellitus is a multi-faceted metabolic disorder where there is increased oxidative stress that contributes to the pathogenesis of this debilitating disease. This has prompted several investigations into the use of antioxidants as a complementary therapeutic approach. Alpha lipoic acid, a naturally occurring dithiol compound which plays an essential role in mitochondrial bioenergetic reactions, has gained considerable attention as an antioxidant for use in managing diabetic complications. Lipoic acid quenches reactive oxygen species, chelates metal ions, and reduces the oxidized forms of other antioxidants such as vitamin C, vitamin E, and glutathione. It also boosts antioxidant defense system through Nrf-2-mediated antioxidant gene expression and by modulation of peroxisome proliferator activated receptors-regulated genes. ALA inhibits nuclear factor kappa B and activates AMPK in skeletal muscles, which in turn have a plethora of metabolic consequences. These diverse actions suggest that lipoic acid acts by multiple mechanisms, many of which have only been uncovered recently. In this review we briefly summarize the known biochemical properties of lipoic acid and then discussed the oxidative mechanisms implicated in diabetic complications and the mechanisms by which lipoic acid may ameliorate these reactions. The findings of some of the clinical trials in which lipoic acid administration has been tested in diabetic patients during the last 10 years are summarized. It appears that the clearest benefit of lipoic acid supplementation is in patients with diabetic neuropathy. PMID:22125537

Compelling evidence is accumulating pointing to a pathophysiological role of the serum-and-glucocorticoid-inducible-kinase-1 (SGK1) in the development and complications of diabetes. SGK1 is ubiquitously expressed with exquisitely high transcriptional volatility. Stimulators of SGK1 expression include hyperglycemia, cell shrinkage, ischemia, glucocorticoids and mineralocorticoids. SGK1 is activated by insulin and growth factors via phosphatidylinositol-3-kinase, 3-phosphoinositide dependent kinase PDK1 and mTOR. SGK1 activates ion channels (including ENaC, TRPV5, ROMK, KCNE1/KCNQ1 and CLCKa/Barttin), carriers (including NCC, NKCC, NHE3, SGLT1 and EAAT3), and the Na+/K+-ATPase. It regulates the activity of several enzymes (e.g. glycogen-synthase-kinase-3, ubiquitin-ligase Nedd4-2, phosphomannose-mutase-2), and transcription factors (e.g. forkhead-transcription-factor FOXO3a, β-catenin, nuclear-factor-kappa-B NFκB). A common SGK1 gene variant (~3–5% prevalence in Caucasians, ~10% in Africans) is associated with increased blood pressure, obesity and type 2 diabetes. In patients suffering from type 2 diabetes, SGK1 presumably contributes to fluid retention and hypertension, enhanced coagulation, and increased deposition of matrix proteins leading to tissue fibrosis such as diabetic nephropathy. Accordingly, targeting SGK1 may favourably influence occurrence and course of type 2 diabetes. PMID:19764891

Until recently, type 2 diabetes was seen as a disease caused by an impaired ability of insulin to promote the uptake and utilisation of glucose. Work on forkhead box protein O (FOXO) transcription factors revealed new aspects of insulin action that have led us to articulate a liver- and beta cell-centric narrative of diabetes pathophysiology and treatment. FOXO integrate a surprisingly diverse subset of biological functions to promote metabolic flexibility. In the liver, they controls the glucokinase/glucose-6-phosphatase switch and bile acid pool composition, directing carbons to glucose or lipid utilisation, thus providing a unifying mechanism for the two abnormalities of the diabetic liver: excessive glucose production and increased lipid synthesis and secretion. Moreover, FOXO are necessary to maintain beta cell differentiation, and diabetes development is associated with a gradual loss of FOXO function that brings about beta cell dedifferentiation. We proposed that dedifferentiation is the main cause of beta cell failure and conversion into non-beta endocrine cells, and that treatment should restore beta cell differentiation. Our studies investigating these proposals have revealed new dimensions to the pathophysiology of diabetes that can be leveraged to design new therapies. PMID:26248647

Abstract The aim of this article is to briefly review available data regarding changes in the structure of microvessels observed in patients with diabetes mellitus, and possible correction by effective treatment. The development of structural changes in the systemic vasculature is the end result of established hypertension. In essential hypertension, small arteries of smooth muscle cells are restructured around a smaller lumen and there is no net growth of the vascular wall, although in some secondary forms of hypertension, a hypertrophic remodelling may be detected. Moreover, in non-insulin-dependent diabetes mellitus a hypertrophic remodelling of subcutaneous small arteries is present. Indices of small resistance artery structure, such as the tunica media to internal lumen ratio, may have a strong prognostic significance in hypertensive and diabetic patients, over and above all other known cardiovascular risk factors. Therefore, regression of vascular alterations is an appealing goal of antihypertensive treatment. Different antihypertensive drugs seem to have different effect on vascular structure. In diabetic hypertensive patients, a significant regression of structural alterations of small resistance arteries with drugs blocking the renin–angiotensin system (angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers) was demonstrated. Alterations in the microcirculation represent a common pathological finding, and microangiopathy is one of the most important mechanisms involved in the development of organ damage as well as of clinical events in patients with diabetes mellitus. Renin–angiotensin system blockade seems to be effective in preventing/regressing alterations in microvascular structure. PMID:20646125
Diabetes is a condition of multifactorial origin, involving several molecular mechanisms related to the intestinal microbiota for its development. In type 2 diabetes, receptor activation and recognition by microorganisms from the intestinal lumen may trigger inflammatory responses, inducing the phosphorylation of serine residues in insulin receptor substrate-1, reducing insulin sensitivity. In type 1 diabetes, the lowered expression of adhesion proteins within the intestinal epithelium favours a greater immune response that may result in destruction of pancreatic β cells by CD8+ T-lymphocytes, and increased expression of interleukin-17, related to autoimmunity. Research in animal models and humans has hypothesized whether the administration of probiotics may improve the prognosis of diabetes through modulation of gut microbiota. We have shown in this review that a large body of evidence suggests probiotics reduce the inflammatory response and oxidative stress, as well as increase the expression of adhesion proteins within the intestinal epithelium, reducing intestinal permeability. Such effects increase insulin sensitivity and reduce autoimmune response. However, further investigations are required to clarify whether the administration of probiotics can be efficiently used for the prevention and management of diabetes. PMID:24939063
The concept that excess superoxide production from mitochondria is the driving, initial cellular response underlying diabetes complications has been held for the past decade. However, results of antioxidant-based trials have been largely negative. In the present review, the data supporting mitochondrial superoxide as a driving force for diabetic kidney, nerve, heart, and retinal complications are reexamined, and a new concept for diabetes complications—mitochondrial hormesis—is presented. In this view, production of mitochondrial superoxide can be an indicator of healthy mitochondria and physiologic oxidative phosphorylation. Recent data suggest that in response to excess glucose exposure or nutrient stress, there is a reduction of mitochondrial superoxide, oxidative phosphorylation, and mitochondrial ATP generation in several target tissues of diabetes complications. Persistent reduction of mitochondrial oxidative phosphorylation complex activity is associated with the release of oxidants from nonmitochondrial sources and release of proinflammatory and profibrotic cytokines, and a manifestation of organ dysfunction. Restoration of mitochondrial function and superoxide production via activation of AMPK has now been associated with improvement in markers of renal, cardiovascular, and neuronal dysfunction with diabetes. With this Perspective, approaches that stimulate AMPK and PGC1α via exercise, caloric restriction, and medications result in stimulation of mitochondrial oxidative phosphorylation activity, restore physiologic mitochondrial superoxide production, and promote organ healing.

Objectives: To investigate and establish the relationship between the use of statin therapy and the risk of development of diabetes. Methods: PubMed and the Cochrane Central Register of Controlled Trials was searched for randomized controlled end-point trials of statins, with more than 1000 subjects and a minimum of one-year follow-up period, published until August 2015. The odds ratio (OR) of diabetes incidence with overall statin therapy as well as with different statins in question was calculated through random effect meta-analysis model. Results: Fourteen studies were included in the analysis with a total of 94,943 participants. Of these, 2392 subjects developed incident diabetes in the statin and 2167 in the placebo groups during a 4-year follow-up. The OR of diabetes incidence with statin therapy was significantly higher as compared with the placebo group (OR=1.11; 95% confidence interval = 1.0 to 1.2; p=0.007). There was an insignificant level of heterogeneity between the included trials (Cochran Q= 19.463, p=0.109, I2=33.20). Subgroup analysis showed that only 2 statins namely, atorvastatin (OR= 1.29; p=0.042) and rosuvastatin (OR = 1.17; px=0.01) were significantly associated. Conclusion: Statin therapy can slightly increase risk of incident diabetes in subjects with hypercholesterolemia. PMID:27652354

The rising global prevalence of diabetes mellitus is accompanied by an increasing burden of morbidity and mortality that is attributable to the complications of chronic hyperglycaemia. These complications include blindness, renal failure and cardiovascular disease. Current therapeutic options for chronic hyperglycaemia reduce, but do not eradicate, the risk of these complications. Success in defining new preventative and therapeutic strategies hinges on an improved understanding of the molecular processes involved in the development of these complications. This Review explores the role of human genetics in delivering such insights, and describes progress in characterizing the sequence variants that influence individual predisposition to diabetic kidney disease, retinopathy, neuropathy and accelerated cardiovascular disease. Numerous risk variants for microvascular complications of diabetes have been reported, but very few have shown robust replication. Furthermore, only limited evidence exists of a difference in the repertoire of risk variants influencing macrovascular disease between those with and those without diabetes. Here, we outline the challenges associated with the genetic analysis of diabetic complications and highlight ongoing efforts to deliver biological insights that can drive translational benefits.

Few attempts have been made to model mathematically the progression of type 2 diabetes. A realistic representation of the long-term physiological adaptation to developing insulin resistance is necessary for effectively designing clinical trials and evaluating diabetes prevention or disease modification therapies. Writing a good model for diabetes progression is difficult because the long time span of the disease makes experimental verification of modeling hypotheses extremely awkward. In this context, it is of primary importance that the assumptions underlying the model equations properly reflect established physiology and that the mathematical formulation of the model give rise only to physically plausible behavior of the solutions. In the present work, a model of the pancreatic islet compensation is formulated, its physiological assumptions are presented, some fundamental qualitative characteristics of its solutions are established, the numerical values assigned to its parameters are extensively discussed (also with reference to available cross-sectional epidemiologic data), and its performance over the span of a lifetime is simulated under various conditions, including worsening insulin resistance and primary replication defects. The differences with respect to two previously proposed models of diabetes progression are highlighted, and therefore, the model is proposed as a realistic, robust description of the evolution of the compensation of the glucose-insulin system in healthy and diabetic individuals. Model simulations can be run from the authors' web page.

We undertook a prospective cohort study to assess risk factors associated with hallux ulceration, and to determine the incidence of healing or amputation, in consecutive patients with diabetes mellitus who were treated over the observation period extending from September 2004 to March 2005, at the Jabir Abu Eliz Diabetic Centre, Khartoum City, Sudan. There were 122 diabetic patients in the cohort (92 males and 30 females) with an overall mean age of 58 +/- 9 years. Fifty-three percent of patients had complete healing within 8 weeks and 43% healed within 20 weeks. The overall mean time to healing was 16 +/- 8 weeks. In 32 (26.2%) patients, osteomyelitic bone was removed, leaving a healed and boneless hallux. The hallux was amputated in 17 (13.9%) patients; in 2 (1.6%) patients it was followed by forefoot amputation and in 7 (5.7%) patients by below-the-knee amputation. In 90 (73.8%) patients the initial lesion was a blister. In conclusion, hallux ulceration is common in patients with diabetes mellitus and is usually preceded by a blister. Neuropathy, foot deformity, and wearing new shoes are common causative factors; and ischemia, osteomyelitis, any form of wound infection, and the size of the ulcer are main outcome determinants. Complete healing occurred in 103 (85%) of diabetic patients with a hallux ulcer. Vascular intervention is important relative to limb salvage when ischemia is the main cause of the ulcer.

Diabetes is a condition of multifactorial origin, involving several molecular mechanisms related to the intestinal microbiota for its development. In type 2 diabetes, receptor activation and recognition by microorganisms from the intestinal lumen may trigger inflammatory responses, inducing the phosphorylation of serine residues in insulin receptor substrate-1, reducing insulin sensitivity. In type 1 diabetes, the lowered expression of adhesion proteins within the intestinal epithelium favours a greater immune response that may result in destruction of pancreatic β cells by CD8+ T-lymphocytes, and increased expression of interleukin-17, related to autoimmunity. Research in animal models and humans has hypothesized whether the administration of probiotics may improve the prognosis of diabetes through modulation of gut microbiota. We have shown in this review that a large body of evidence suggests probiotics reduce the inflammatory response and oxidative stress, as well as increase the expression of adhesion proteins within the intestinal epithelium, reducing intestinal permeability. Such effects increase insulin sensitivity and reduce autoimmune response. However, further investigations are required to clarify whether the administration of probiotics can be efficiently used for the prevention and management of diabetes.
Background Language barrier is an important determinant of health care access and health. We examined the associations of English proficiency with type-2 diabetes (T2DM) and diabetic retinopathy (DR) in Asian Indians living in Singapore, an urban city where English is the predominant language of communication. Methods This was a population-based, cross-sectional study. T2DM was defined as HbA1c ≥6.5%, use of diabetic medication or a physician diagnosis of diabetes. Retinal photographs were graded for the severity of DR including vision-threatening DR (VTDR). Presenting visual impairment (VI) was defined as LogMAR visual acuity > 0.30 in the better-seeing eye. English proficiency at the time of interview was assessed. Results The analyses included 2,289 (72.1%) English-speaking and 885 (27.9%) Tamil- speaking Indians. Tamil-speaking Indians had significantly higher prevalence of T2DM (46.2 vs. 34.7%, p < 0.001) and, among those with diabetes, higher prevalence of DR (36.0 vs. 30.6%, p < 0.001), VTDR (11.0 vs. 6.5%, p < 0.001), and VI (32.4 vs. 14.6%) than English speaking Indians. Oaxaca decomposition analyses showed that the language-related discrepancies (defined as the difference in prevalence between persons speaking different languages) in T2DM, DR, and VTDR could not be fully explained by socioeconomic measures. Conclusions In an English dominant society, Tamil-speaking Indians are more likely to have T2DM and diabetic retinopathy. Social policies and health interventions that address language-related health disparities may help reduce the public health impact of T2DM in societies with heterogeneous populations. PMID:22974298

Diabetes mellitus is one of the major risk factors for cardiovascular disease which is the leading cause of death in the U.S. Increasing prevalence of diabetes and diabetic atherosclerosis makes identification of molecular mechanisms by which diabetes promotes atherogenesis an important task. Targeting common pathways may ameliorate both diseases. This review focuses on well known as well as newly discovered mechanisms which may represent promising therapeutic targets. PMID:18695749

It is well established that osteoporosis and diabetes are prevalent diseases with significant associated morbidity and mortality. The relationship between diabetes and bone disease is less well defined but recent data seem to suggest that diabetes and the complications associated with it can be detrimental to bone health. Furthermore, it appears that thiazolidinediones, medications used in the treatment of diabetes, can also cause bone loss and increase the risk of fracture. This article will review the relationship between diabetes and bone health.

Twenty-one families were selected from the published reports in which the propositus had the triad of juvenile diabetes mellitus, diabetes insipidus, and optic atrophy. The data were consistent with the hypothesis of an autosomal gene which, in the homozygote, causes juvenile diabetes mellitus and one or more of diabetes insipidus, optic atrophy, and nerve deafness. Heterozygotes appear to have an increased probability of developing juvenile diabetes mellitus. PMID:881709

Background: Empowerment of people with diabetes means integrating diabetes with identity. However, others’ stigmatization can influence it. Although diabetes is so prevalent among Iranians, there is little knowledge about diabetes-related stigma in Iran. The present study explored diabetes-related stigma in people living with type 1 diabetes in Isfahan. Materials and Methods: A conventional content analysis was used with in-depth interview with 26 people with and without diabetes from November 2011 to July 2012. Results: A person with type 1 diabetes was stigmatized as a miserable human (always sick and unable, death reminder, and intolerable burden), rejected marriage candidate (busy spouse, high-risk pregnant), and deprived of a normal life [prisoner of (to must), deprived of pleasure]. Although, young adults with diabetes undergo all aspects of the social diabetes-related stigma; in their opinion they were just deprived of a normal life Conclusion: It seems that in Isfahan, diabetes-related stigma is of great importance. In this way, conducting an appropriate intervention is necessary to improve the empowerment process in people with type 1 diabetes in order to reduce the stigma in the context. PMID:23983731

The rising prevalence of diabetes estimated at 3.6 million people in the UK represents a major public health and socioeconomic burden to our National Health Service. Diabetes and its associated complications are of a growing concern. Diabetes-related foot complications have been identified as the single most common cause of morbidity among diabetic patients. The complicating factor of underlying peripheral vascular disease renders the majority of diabetic foot ulcers asymptomatic until latter evidence of non-healing ulcers become evident. Therefore, preventative strategies including annual diabetic foot screening and diabetic foot care interventions facilitated through a multidisciplinary team have been implemented to enable early identification of diabetic patients at high risk of diabetic foot complications. The National Diabetes Foot Care Audit reported significant variability and deficiencies of care throughout England and Wales, with emphasis on change in the structure of healthcare provision and commissioning, improvement of patient education and availability of healthcare access, and emphasis on preventative strategies to reduce morbidities and mortality of this debilitating disease. This review article aims to summarise major risk factors contributing to the development of diabetic foot ulcers. It also considers the key evidence-based strategies towards preventing diabetic foot ulcer. We discuss tools used in risk stratification and classifications of foot ulcer.

Diabetes mellitus and cancer are common conditions, and their co-diagnosis in the same individual is not infrequent. The relative risks associated with type 2 diabetes are greater than twofold for hepatic, pancreatic, and endometrial cancers. The relative risk is somewhat lower, at 1.2-1.5-fold for colorectal, breast, and bladder cancers. In comparison, the relative risk of lung cancer is less than 1. The evidence for other malignancies (e.g. kidney, non-Hodgkin lymphoma) is inconclusive, whereas prostatic cancer occurs less frequently in male patients with diabetes. The potential biologic links between the two diseases are incompletely understood. Evidence from observational studies suggests that some medications used to treat hyperglycemia are associated with either increased or reduced risk of cancer. Whereas anti-diabetic drugs have a minor influence on cancer risk, drugs used to treat cancer may either cause diabetes or worsen pre-existing diabetes. If hyperinsulinemia acts as a critical link between the observed increased cancer risk and type 2 diabetes, one would predict that patients with type 1 diabetes would have a different cancer risk pattern than patients with type 2 diabetes because the former patients are exposed to lower levels of exogenous administered insulin. Obtained results showed that patients with type 1 diabetes had elevated risks of cancers of the stomach, cervix, and endometrium. Type 1 diabetes is associated with a modest excess cancer risk overall and risks of specific cancers that differ from those associated with type 2 diabetes.

The social and economic burden of diabetes is large and growing. Diabetes is a significant public health issue in the Appalachian region; women constitute approximately 50% of those diagnosed with diabetes. This cross-sectional study examined the relationship among sociodemographic, anthropometric, lifestyle, and psychosocial factors (cognitive and affective representations) and perceived risk of diabetes in non-diabetic, non-elderly (21-50 years) Appalachian women residing in West Virginia (N = 202). Participants were recruited through social media, flyers, and a newsletter from the West Virginia University Extension. The final survey was conducted from March 2015 to June 2015. Bivariate analyses were used to examine unadjusted relations among sociodemographic, anthropometric, lifestyle, and psychosocial factors and comparative perceived risk of diabetes. In a multivariable logistic regression model, we found that younger age, higher body mass index, non-White race, greater diabetes knowledge, personal control, and moderate amounts of physical activity were significantly, positively associated with higher diabetes risk perception (p < .05). Our results indicated that diabetes knowledge, personal control, and physical activity were related to diabetes risk perception among Appalachian women. Understanding perceived diabetes-related risk may aid in the development of effective intervention strategies to reduce the burden of diabetes among Appalachian and other populations. These cross-sectional findings need further evaluation in longitudinal studies.

Diabetes mellitus (DM) is a rapidly growing epidemic in the United States, and it is expected to affect 592 million individuals within the next 20 years. Diabetic retinopathy (DR) and diabetic macular edema (DME) are the 2 most common ophthalmic complications of DM. DR is the leading cause of blindness among working-age adults around the world, and development of DR is tied to DM disease duration. With the only identifier of early markers of DR being a complete ophthalmic exam, early signs of the disease are asymptomatic. Yearly, or at least every other year, ophthalmic exams are recommended for all patients with DM; but often, individuals with DM have not undergone screening exams and do not have regular eye exams until vision loss has occurred. With spending estimates of $490 million to treat the vision complications of DM, it is clear that DR and DME impose a substantial burden for patients, caregivers, and healthcare systems.

Introduction: Sodium-glucose co-transporter 2 (SGLT-2) inhibitors are relatively new antihyperglycemic agents that lower renal glucose reabsorption. They are used as adjunctive therapy to standard diabetes treatment. Case Report: We present the case of a 62-year-old woman with a past medical history of type 2 diabetes mellitus and sudden-onset diabetic ketoacidosis (DKA). Use of canagliflozin, a SGLT-2 inhibitor, was determined to be the cause of the DKA. The patient ultimately recovered after 5 days in the intensive care unit. She was changed to long- and short-acting insulins and instructed to avoid canagliflozin. Conclusion: Although SGLT-2 inhibitors are effective at lowering a patient’s hemoglobin A1C, physicians must be aware of the rare but dangerous potential adverse effect of inducing DKA. This article reports an illustrative case and presents a review of the literature. PMID:27635409

Pathologic study of a disease provides insights into the precise mechanisms and targets of damage and may provide insights into new therapies. The main targets in diabetic neuropathy are myelinated and unmyelinated fibers as dysfunction and damage to them explains the symptoms of painful neuropathy and the major end points of foot ulceration and amputation as well as mortality. Demyelination and axonal degeneration are established hallmarks of the pathology of human diabetic neuropathy and were derived from pioneering light and electronmicroscopic studies of sural nerve biopsies in the late 1960s and early 1970s. Additional abnormalities, which are relevant to the pathogenesis of human diabetic neuropathy, include pathology of the microvessels and extracellular space. Intraepidermal and sudomotor nerve quantification in skin biopsies provides a minimally invasive means for the detection of early nerve damage. Studies of muscle biopsies are limited and show significant alterations in the expression of neurotrophins, but limited changes in muscle fiber size and capillary density.

Cell activation or apoptosis leads to plasma membrane blebbing and microparticles (MPs) release in the extracellular space. MPs are submicron membrane vesicles, which harbour a panel of oxidized phospholipids and proteins specific to the cells they derived from. MPs are found in the circulating blood of healthy volunteers. MPs levels are increased in many diseases, including cardiovascular diseases with high thrombotic risk. Exposure of negatively charged phospholipids and tissue factor confers a procoagulant potential to MPs. Elevation of plasma MPs levels, particularly those of endothelial origin, reflects cellular injury and appears now as a surrogate marker of vascular dysfunction. Recent studies demonstrate an elevation of circulating levels of MPs in diabetes. MPs could also be involved in the development of vascular complications in diabetes for they stimulate pro-inflammatory responses in target cells and promote thrombosis, endothelial dysfunction and angiogenesis. Thus, these studies provide new insight in the pathogenesis and treatment of vascular complications of diabetes.

Type 1 diabetes mellitus (T1D) and type 2 diabetes (T2D) mellitus are on the increase in children and adolescents. An increase in T2D is linked to the increasing rates of obesity in children. Usually, in both children and adults, T1D is treated with insulin while T2D is treated with metformin. There are other classes of drugs that are under assessment for their safety and efficacy in relation to pediatric patients. Most of these new drugs, however, have not been studied in children. Thus, the repertoire of drugs that are available to treat diabetes in children is limited. In this review, we outline the current pathology and treatment and future therapies of T1D mellitus and T2D mellitus in children. PMID:27073417

In primary health care, the specific contribution nurses make to the community they serve manifests itself clearly when treating individuals suffering from chronic illnesses, with whom nurses basically fulfill an educational role. In the control of diabetics, a nurse plays a fundamental role in their periodical check-ups and their education about diabetes. Nonetheless, it is not a common practice to provide an adequate treatment for these pathologies nor oral hygiene self methods during these office visits, when the time requirements are not extensive and when the information available highlights the need to contemplate oral hygiene in both educational aspects and check-ups for diabetics, regardless of his/her age or the degree of metabolic control.
Diabetic nephropathy (DN) is a chronic complication of diabetes and the most common cause of end-stage kidney disease. It has been reported that multiple factors are involved in the pathogenesis of DN, while the molecular mechanisms that lead to DN are still not fully understood. Numerous risk factors for the development of diabetic nephropathy have been proposed, including ethnicity and inherited genetic differences. Recently, with the development of high-throughput technologies, there is emerging evidence that suggests the important role of epigenetic mechanisms in the pathogenesis of DN. Epigenetic regulations, including DNA methylation, noncoding RNAs, and histone modifications, play a pivotal role in DN pathogenesis by a second layer of gene regulation. All these findings can contribute to developing novel therapies for DN.

The National Institute of Diabetes and Digestive and Kidney Diseases-supported Kidney Research National Dialogue (KRND) asked the scientific community to formulate and prioritize research objectives that would improve our understanding of kidney function and disease. Several high-priority objectives for diabetic nephropathy were identified in data and sample collection, hypothesis generation, hypothesis testing, and translation promotion. The lack of readily available human samples linked to comprehensive phenotypic, clinical, and demographic data remains a significant obstacle. With data and biological samples in place, several possibilities exist for using new technologies to develop hypotheses. Testing novel disease mechanisms with state-of-the-art tools should continue to be the foundation of the investigative community. Research must be translated to improve diagnosis and treatment of people. The objectives identified by the KRND provide the research community with future opportunities for improving the prevention, diagnosis, and treatment of diabetic nephropathy.

In view of the alarming increase in the incidence of diabetes mellitus in Malaysia, we conducted a study to assess the awareness of complications of diabetes among the diabetics attending the peripheral clinics in Melaka. The study period was from January 2007 to December 2007. 351 patients were included in the study. 79.8% were aware of the complications of diabetes mellitus and 87.2% were aware that diabetes can affect the eyes. However, only 50% of the patients underwent an ophthalmological evaluation. Although awareness was good, the motivation to undergo the assessment was poor.
A variety of treatment options are available for the treatment of diabetic macular edema. They include laser photocoagulation, anti-VEGF drugs, intravitreal steroids, and vitrectomy with or without release of vitreoretinal traction. A full understanding of the physiological mechanisms of these treatment modalities allows sensible combination of treatment options. Retinal photocoagulation has repeatedly been shown to improve retinal oxygenation, as does vitrectomy. Oxygen naturally reduces VEGF production and thereby decreases leakage of plasma proteins from capillaries into the tissue. In addition, vitrectomy allows faster clearance of cytokines, such as VEGF, from the retina into the vitreous cavity. The VEGF-lowering effect of photocoagulation and vitrectomy can be augmented with anti-VEGF drugs and corticosteroids reduce the effect of VEGF on capillary permeability. Starling's law explains vasogenic edema, which is controlled by osmotic and hydrostatic gradients between vessel and tissue. It explains how VEGF-induced vascular permeability causes plasma protein to leak into the tissue interstitial space, thus decreasing the osmotic pressure gradient between vessel and tissue, resulting in water accumulation, i.e. edema. This is reversed by reducing VEGF production, which is achieved with laser treatment; or by removing VEGF with antibodies or vitrectomy; or by reducing the permeability effect with steroids. At the same time, Starling's law takes into account hemodynamic changes that affect the hydrostatic gradient. High arterial blood pressure and hypoxic vasodilatation increase the hydrostatic pressure in the microcirculation, which increases water flux from vessel to tissue and induce edema. Treatment of arterial hypertension or reversal of retinal hypoxia with laser reverses this pathophysiology and reduces edema. Newton's third law explains, that vitreoretinal traction decreases hydrostatic tissue pressure in the retina, increases the pressure gradient

Diabetic and sickle retinopathy have features in common--for example, venous dilatation, microaneurysms, and capillary closure preceding neovascularisation. Bearing in mind that haemoglobin in poorly controlled diabetes is abnormal and that extremely low oxygen tensions (known to cause sickling) exist in the healthy cat retina, we wished to explore the possibility that diabetic blood, like that of sickle cell disease, may become more viscous when deoxygenated. To do this we measured whole blood viscosity, under oxygenated and deoxygenated conditions, of 23 normal persons, 23 diabetic patients without retinopathy, and 34 diabetic patients with retinopathy. The shear rate used was 230 s-1, which is similar to that thought to prevail in the major retinal veins. The viscosity of blood from normal persons, corrected for packed cell volume, did not change significantly on deoxygenation: mean 4.54 (SD 0.38) cps, versus, 4.57 (0.39) paired t test, p = 0.66. Similarly the blood from diabetics without retinopathy showed no change: 4.42 (0.45) versus 4.42 (0.30), p = 0.98; whereas the blood from patients with retinopathy changed from 4.82 (0.48) to 4.95 (0.63), p = 0.027. The hypoxic viscosity ratio (deoxygenated divided by oxygenated viscosity) correlated with total serum cholesterol (r = 0.44, p = 0.018) but not with HbA1, serum glucose, triglycerides, or age. A disproportionate increase in venous viscosity relative to arterial viscosity would lead to increased intraluminal and transmural pressure and therefore exacerbate leakage across capillary walls.

Women with normal glucose tolerance pre-gravid and developing gestational diabetes in late gestation have subclinical metabolic dysfunction prior to conception compared with women with normal glucose tolerance. Because of the 60 % decrease in insulin sensitivity with normal pregnancy, these women develop clinical hyperglycaemia/gestational diabetes in late gestation. The metabolic dysfunction includes impaired insulin response, decreased hepatic suppression of glucose production during insulin infusion and decreased insulin-stimulated glucose uptake in skeletal muscle, i.e. peripheral insulin resistance. The insulin resistance in normal glucose tolerance pregnancy is related to a decrease in the post-receptor insulin signalling cascade, specifically decreased insulin receptor substrate 1 tyrosine phosphorylation. In women with normal glucose tolerance this is reversed post-partum. In contrast, in gestational diabetes, in addition to the decrease in insulin receptor substrate 1 tyrosine phosphorylation, there is an additional decrease in tyrosine phosphorylation of the intracellular portion of the insulin receptor that is not related to the insulin receptor protein content. Post-partum women with gestational diabetes, who had retention of gestational weight gain, had no significant improvement in insulin sensitivity and increased inflammation expressed as increased plasma and skeletal muscle tumour necrosis factor alpha. The increased inflammation or meta-inflammation is a hallmark of obesity and during pregnancy develops in both white adipose tissue and placenta. Last gene array studies of placenta were associated with alterations in gene expression relating primarily to lipid in contrast to glucose metabolic pathways in gestational diabetes compared with Type 1 diabetes. Future studies are directed at decreasing inflammation prior to and during pregnancy using various lifestyle and nutritional interventions. PMID:24341419
Diabetics are no longer concerned with scheduling activities around peaking insulin levels since the use of an external pump from Pacesetter Systems, Inc. used to deliver insulin continuously at a preprogrammed individually adjusted rate. The pump wearer can lead a more normal existence, even participate in sports or travel, and there is an even greater benefit. Research indicates that infusion of "short acting" insulin in tiny amounts over a long period - instead of "long- acting" insulin has helped many diabetics achieve better control of blood sugar levels, thereby minimizing the possibility of complications and, in some cases, even halting the progression of complications.

Diabetes mellitus (DM) is a important health problem that induces ernestful complications and it causes significant morbidity owing to specific microvascular complications such as, retinopathy, nephropathy and neuropathy, and macrovascular complications such as, ischaemic heart disease, and peripheral vasculopathy. It can affect children, young people and adults and is becoming more common. Ocular complications associated with DM are progressive and rapidly becoming the world’s most significant cause of morbidity and are preventable with early detection and timely treatment. This review provides an overview of five main ocular complications associated with DM, diabetic retinopathy and papillopathy, cataract, glaucoma, and ocular surface diseases. PMID:25685281
During the last years, a contribution of antipsychotic drugs in the increase of diabetes prevalence in schizophrenic population has been repetitively suggested. The debate focused mainly on the second-generation antipsychotics. The analysis of the scientific literature indicates however that this discussion is not recent and an increase of diabetes prevalence in schizophrenic populations was already described before the introduction of neuroleptics. Then, after the introduction of the first neuroleptics in the 1950s, an increase of diabetes prevalence was reported among treated patients and the same alarms occurred in the 1990s after the introduction of second-generation antipsychotics. These treatments were related to an increase of glucose tolerance impairment, type II diabetes and diabetic acidoketosis. Recent epidemiological studies have confirmed the increase prevalence of diabetes in schizophrenic patients, particularly in schizophrenic patients before any antipsychotic treatment. Among the suggested mechanisms, there are sedentary life (due to hospitalisation and sedative effects of neuroleptics), food imbalance, shared genetic factors for diabetes and schizophrenia. Moreover, the frequency of the metabolic syndrome is increased in schizophrenic populations. This syndrome associates blood glucose increase, lipid metabolism disorders and android obesity. This could explain--via an increase of the cortisol production--the increase of mortality due to cardiovascular diseases observed in schizoprhenic patients. Thus, it seems well established that schizophrenia is associated with an increased risk for diabetes. It is however more difficult to evaluate the role of antipsychotic treatment as a causative factor of diabetes. Indeed, there are many published case reports or diabetes or diabetic acidoketosis after an antipsychotic treatment, but the level of evidence in controlled trials is low. Many studies were performed on large databases, but were retrospective

Diabetes is the fastest growing chronic condition in Australia, affecting 1.7 million Australians, requiring daily self-care, and known to reduce quantity and quality of life. On average, people with diabetes experience greater emotional distress than those without diabetes. One source of distress can be the language used to refer to diabetes, its management and the person with diabetes. The way verbal and written language is used reflects and shapes people's thoughts, beliefs and behaviours. Language has the power to persuade, change or reinforce beliefs and stereotypes - for better or worse. Words do more than reflect people's reality: they create reality and affect how people view the world and their diabetes. Language needs to engage people with diabetes and support their self-care efforts. Importantly, language that de-motivates or induces fear, guilt or distress needs to be avoided and countered. Diabetes Australia believes optimal communication increases the motivation, health and well-being of people with diabetes, and that careless or negative language can be de-motivating, is often inaccurate, and can be harmful. Diabetes Australia developed this position statement to encourage greater awareness of the language surrounding diabetes and provide recommendations for more careful and positive language use.

Diabetic nephropathy is one of the most frequent and serious complications of diabetes mellitus. Soybeans have been shown to reduce urinary albumin excretion and total cholesterol in non-diabetic patients with nephrotic syndrome. However, reports focusing specifically on diabetic nephropathy are scarce and the available results are inconsistent. It was reported that soybean consumption reduced urinary protein excretion in type 1 diabetic patients with diabetic nephropathy, whereas it was found to elicit an increase in urinary protein excretion when soybeans were consumed by type 2 diabetic patients. This study aims to investigate the effects of soybean in diabetic nephropathy, particularly the effects of consuming soybeans on the histopathology of diabetic nephropathy, using aquaporin (AQP) and osteopontin (OPN) expression as diagnostic markers. Male Sprague-Dawley rats were assigned to one of three groups: control, diabetic with red chow diet and diabetic with soybean diet. For histological examination, the expression of OPN and AQP, renal function and hemoglobin A1c were evaluated at the end of the study. Improvements in glomerular and tubulointerstitial lesions were demonstrated in the diabetic rat group given a soybean diet. OPN and AQP expression were suppressed in the kidney specimens of diabetic rats with the soybean diet. In conclusion, soybeans may prevent the weight loss and morphological disruption of the kidney associated with diabetes mellitus. Soybeans also may improve glycemic control. It seems likely that long-term control of blood glucose levels using a soybean diet could prevent the progression of diabetes mellitus, and therefore, nephropathy could be prevented. PMID:18955330

Colorectal cancer is associated with diabetes mellitus and both of these common conditions are often managed together by a surgeon. The surgical focus is usually upon cancer treatment rather than diabetes management. The relationship between colorectal cancer and diabetes is a complex one and can raise problems in both diagnosis and the management of patients with both conditions. This literature review explores the relationship between diabetes, diabetic treatment and colorectal cancer and addresses the issues that arise in diagnosing and treating this patient group. By highlighting these difficulties, this review aims to improve understanding and to provide clearer insight into both surgical and non-surgical management. PMID:24334910

The prevalence of new cases of diabetes continues to increase, and the health burden for those with diabetes remains high. This is attributable, in part, to low adoption of evidence-based interventions for diabetes prevention and control. Law is a critical tool for health improvement, yet assessments reported in this paper indicate that federal, state, and local laws give only partial support to guidelines and evidence-based interventions relevant to diabetes prevention and control. Public health practitioners and policymakers who are concerned with the human, fiscal, and economic costs of the epidemic can explore new ways to translate the evidence base for diabetes prevention and control into effective laws and policies.

The number of people with diabetes mellitus is increasing and cataracts are one of the most common causes of visual impairment in these subjects. Advances in cataract surgical techniques and instrumentation have generally improved the outcomes; however,surgery may not be safe and effective in certain individuals with pre-existing retinal pathology or limited visual potential. This review article aims to address different aspects surrounding cataracts in diabetic patients. In a computerized MEDLINE search,relevant studies were selected by two authors using the keywords “diabetes mellitus”, “cataract”, “diabetic retinopathy” and “diabetic maculopathy”. PMID:23479523

The epidemic nature of diabetes mellitus in different regions is reviewed. The Middle East and North Africa region has the highest prevalence of diabetes in adults (10.9%) whereas, the Western Pacific region has the highest number of adults diagnosed with diabetes and has countries with the highest prevalence of diabetes (37.5%). Different classes of diabetes mellitus, type 1, type 2, gestational diabetes and other types of diabetes mellitus are compared in terms of diagnostic criteria, etiology and genetics. The molecular genetics of diabetes received extensive attention in recent years by many prominent investigators and research groups in the biomedical field. A large array of mutations and single nucleotide polymorphisms in genes that play a role in the various steps and pathways involved in glucose metabolism and the development, control and function of pancreatic cells at various levels are reviewed. The major advances in the molecular understanding of diabetes in relation to the different types of diabetes in comparison to the previous understanding in this field are briefly reviewed here. Despite the accumulation of extensive data at the molecular and cellular levels, the mechanism of diabetes development and complications are still not fully understood. Definitely, more extensive research is needed in this field that will eventually reflect on the ultimate objective to improve diagnoses, therapy and minimize the chance of chronic complications development.

Diabetes and diabetic kidney diseases have continually exerted a great burden on our society. Although the recent advances in medical research have led to a much better understanding of diabetic kidney diseases, there is still no successful strategy for effective treatments for diabetic kidney diseases. Recently, treatment of diabetic kidney diseases relies either on drugs that reduce the progression of renal injury or on renal replacement therapies, such as dialysis and kidney transplantation. On the other hand, searching for biomarkers for early diagnosis and effective therapy is also urgent. Discovery of microRNAs has opened to a novel field for posttranscriptional regulation of gene expression. Results from cell culture experiments, experimental animal models, and patients under diabetic conditions reveal the critical role of microRNAs during the progression of diabetic kidney diseases. Functional studies demonstrate not only the capability of microRNAs to regulate expression of target genes, but also their therapeutic potential to diabetic kidney diseases. The existence of microRNAs in plasma, serum, and urine suggests their possibility to be biomarkers in diabetic kidney diseases. Thus, identification of the functional role of microRNAs provides an essentially clinical impact in terms of prevention and treatment of progression in diabetic kidney diseases as it enables us to develop novel, specific therapies and diagnostic tools for diabetic kidney diseases.

Periodontal disease is a high prevalent disease. In the United States 47.2% of adults ≥ 30 years old have been diagnosed with some type of periodontitis. Longitudinal studies have demonstrated a two-way relationship between diabetes and periodontitis, with more severe periodontal tissue destruction in diabetic patients and poorer glycemic control in diabetic subjects with periodontal disease. Periodontal treatment can be successful in diabetic patients. Short term effects of periodontal treatment are similar in diabetic patients and healthy population but, more recurrence of periodontal disease can be expected in no well controlled diabetic individuals. However, effects of periodontitis and its treatment on diabetes metabolic control are not clearly defined and results of the studies remain controversial. PMID:26185600

Diabetes mellitus is the main health problem affecting Mexico's population. The mechanisms by which susceptibility to it is acquired and diabetes develops are topics of ongoing research. In order to prevent type 2 diabetes, one of the challenges is to fully understand gestational diabetes and the hormonal changes and altered carbohydrate metabolism that are associated with it during fetal development. A recent study by the Instituto Nacional de Perinatología found a 12.9% prevalence of gestational diabetes; if the current criteria suggested by the American Diabetes Association were applied, this figure would rise to almost 30%. Identifying mothers and children at high risk of developing diabetes mellitus and its comorbid conditions will help facilitate the timely implementation of preventive measures. This will be a rational use of economic resources in Mexico that will vitally benefit public health.

The worksite presents special challenges not only for employees with diabetes, but also for their supervisors. Supervisors wonder whether certain behaviors are willful misconduct or indicative of health problems, as well as if and how to accommodate employees with diabetes to meet the needs of the employees and the company, within the law. The purpose of this research was to pilot test an innovative educational program for supervisors of employees with diabetes to benefit employees' health and diabetes control while meeting the legal requirements of the Americans with Disabilities Act (ADA). Nine supervisors completed a 6-hour program that included innovative teaching strategies--"living the life" of a person with diabetes for 2 days and case studies to practice decision making according to the ADA. The program increased supervisors' reported self-efficacy for supervising employees with diabetes and should improve work life for employees with diabetes, ultimately decreasing employers' health care costs.

The clinical significance of type 2 diabetes mellitus is not confined to metabolic disorders. A serious problem is also affective pathology that occurs in the majority (30-70%) of patients. However, diagnostics and correction of anxiety and depressive disorders associated with diabetes are often given insufficient attention. Many studies showed relationship between affective disorders and low adherence to the prescribed treatment resulting in general deterioration of clinical prognosis of diabetes. This review article describes the basic mechanisms behind the interrelation of affective disorders and diabetes. The role of persistent subclinical inflammation in diabetes and depression is discussed. The influence of emotional stress on the activation of the hypothalamic-pituitary-adrenal axis on the overproduction of cortisol is emphasized. The similarity of some structural changes in the brain tissue in diabetes and depression is discussed. Effect of endocrine disruption in the emotional sphere is demonstrated. Mechanisms responsible for the development of diabetes and its complications provoked by depression are considered.

Type 2 diabetes mellitus (T2DM) has been described as a new epidemic. Approximately 285 million people worldwide suffer from diabetes, and this number is predicted to increase by about 50% by year 2030.This article will review oral health manifestations of diabetes, and discuss associations between periodontal disease and diabetes. Although there is a strong body of evidence that supports the relationship between oral health and T2DM, oral health awareness is lacking among patients with diabetes and other health professionals. There is a need for the treating physician to be educated about the various oral manifestations of diabetes so that they can be diagnosed early and timely referrals to oral health specialists can be made. The established link between periodontitis and diabetes calls for an increased need to study ways to control both diseases, particularly among populations with health disparities and limited access to oral and health care.

Diabetes was induced in adult male albino rats by a single intravenous injection of streptozotocin (75 mg/kg body weight). The diabetes was allowed to stabilize for at least 15 days, whereafter the testicular and seminal vesicle histology was studied at various time intervals. Reduction in testis weights and tubule diameters was significant after 2 weeks of diabetes. The changes in seminiferous tubules ranged from premature sloughing of epithelium to total cessation of spermatogenesis. The testicular histology of diabetic animals frequently greatly simulated the situation described following hypophysectomy. By subjective visual assessment the number of Leydig cells was found to be normal or reduced in all of the diabetic animals. Diabetes was also demonstrated to induce seminal vesicle atrophy, which did not show any correlation with the degree of testicular lesions. The possible etiology of testicular damage in diabetic animals is discussed.

Cysteine is arguably the most reactive amino acid in protein. A wide range of cysteine derivatives is formed in vivo, resulting from oxidation, nitrosation, alkylation and acylation reactions. This review describes succination of proteins, an irreversible chemical modification of cysteine by the Krebs cycle intermediate, fumarate, yielding S-(2-succinyl)cysteine (2SC). Intracellular fumarate concentration and succination of proteins are increased by hyperpolarization of the inner mitochondrial membrane and develop in concert with mitochondrial and oxidative stress in diabetes. Increased succination of glyceraldehyde-3-phosphate dehydrogenase explains the loss in specific activity of this enzyme in muscle of streptozotocin-diabetic rats and increased succination of adiponectin may explain the decreased secretion of adiponectin from adipose tissue in type 2 diabetes. In addition to GAPDH and adiponectin, other succinated proteins identified in adipocytes include cytoskeletal proteins (tubulin, actin) and chaperone proteins in the endoplasmic reticulum. Succination of adipocyte protein in vitro is inhibited by uncouplers of oxidative phosphorylation and by inhibitors of ER stress. 2SC serves as a biomarker of mitochondrial stress and recent studies suggest that succination is the mechanistic link between mitochondrial and ER stress in diabetes.

The control of diabetes is an interdisciplinary endeavor, which includes a significant biomedical engineering component, with traditions of success beginning in the early 1960s. It began with modeling of the insulin-glucose system, and progressed to large-scale in silico experiments, and automated closed-loop control (artificial pancreas). Here, we follow these engineering efforts through the last, almost 50 years. We begin with the now classic minimal modeling approach and discuss a number of subsequent models, which have recently resulted in the first in silico simulation model accepted as substitute to animal trials in the quest for optimal diabetes control. We then review metabolic monitoring, with a particular emphasis on the new continuous glucose sensors, on the analyses of their time-series signals, and on the opportunities that they present for automation of diabetes control. Finally, we review control strategies that have been successfully employed in vivo or in silico, presenting a promise for the development of a future artificial pancreas and, in particular, discuss a modular architecture for building closed-loop control systems, including insulin delivery and patient safety supervision layers. We conclude with a brief discussion of the unique interactions between human physiology, behavioral events, engineering modeling and control relevant to diabetes.

Recent advances in fluorescence spectroscopy of the lens reveal the potential of a non-invasive device and methodology to sensitively measure changes in the lens of the eye associated with diabetes mellitus. The system relies on the detection of the spectrum of fluorescence emitted from a selected volume (approximately 1/10 mm3) of the lens of living human subjects using low power excitation illumination from monochromatic light sources. The sensitivity of this technique is based on the measurement of the fluorescence intensity in a selected region of the fluorescence spectrum and normalization of this fluorescence with respect to attenuation (scattering and absorption) of the incident excitation light. The amplitude of the unshifted Rayleigh line, measured as part of the fluorescence spectrum, is used as a measure of the attenuation of the excitation light in the lens. Using this methodology we have demonstrated that the normalized lens fluorescence provides a more sensitive discrimination between diabetic and non-diabetic lenses than more conventional measurements of fluorescence intensity from the lens. The existing instrumentation will be described as well as the proposed design for a commercial version of the instrument expected to be ready for FDA trials by late 1992. The results from clinical measurements are used to describe a relationship between normalized lens fluorescence and hemoglobin A1c levels in diabetic patients.

Activities of erythrocyte aldose reductase were compared in 34 normal subjects, 45 diabetic patients, and nine young men following immersion in water at 25, 39, and 42° C. Mean basal enzyme activity was 1.11 (SEM 0.12) U/g Hb and 2.07 (SEM 0.14) U/g Hb in normal controls and diabetic patients, respectively ( P<0.0001). Activities of the enzyme showed a good correlation with hemaglobin A1 (HbA1) concentrations ( P<0.01) but not with fasting plasma glucose concentrations. After immersion at 42° C for 10 min, enzyme activity was increased by 37.6% ( P<0.01); however, the activity decreased by 52.2% ( P<0.005) after immersion for 10 min at 39° C and by 47.0% ( P<0.05) at 25° C. These changes suggest that heat stress might aggravate diabetic complications, and body exposure to hot environmental conditions is not recommended for diabetic patients.

Use of technology in diabetes management is rapidly advancing and has the potential to help individuals with diabetes achieve optimal glycemic control. Over the past 40 years, several devices have been developed and refined, including the blood glucose meter, insulin pump, and continuous glucose monitor. When used in tandem, the insulin pump and continuous glucose monitor have prompted the Artificial Pancreas initiative, aimed at developing control system for fully automating glucose monitoring and insulin delivery. In addition to devices, modern technology, such as the Internet and mobile phone applications, have been used to promote patient education, support, and intervention to address the behavioral and emotional challenges of diabetes management. These state-of-the-art technologies not only have the potential to improve clinical outcomes, but there are possible psychological benefits, such as improved quality of life, as well. However, practical and psychosocial limitations related to advanced technology exist and, in the context of several technology-related theoretical frameworks, can influence patient adoption and continued use. It is essential for future diabetes technology research to address these barriers given that the clinical benefits appear to largely depend on patient engagement and consistence of technology use.

Diabetes is one of the foremost public health issues worldwide that can lead to complications in many organ systems, and has become a significant cause of morbidity and mortality in Korea. According to data from the National Health Insurance Service (NHIS), about 2.7 million Koreans (8.0%) aged 30 years or older had type 2 diabetes mellitus (T2DM) in 2013. The prevalence of T2DM increased with age and rose from 5.6% in 2006 to 8.0% in 2013. Using data based on The Health Screening Service of the NHIS, 25% of Korean adults were reported to have prediabetes in 2013. The prevalence of an impaired fasting glucose tended to increase over time from 21.5% in 2006 to 25.0% in 2013. Even though nationwide health screening has been regularly conducted as a public service, the proportion of undiagnosed cases of diabetes was still reported to be on the higher side in the latest study. Based on the results of these epidemic studies, further actions will be needed to effectively implement lifestyle changes on a social level and increase measures for the early detection of diabetes to stem the tide of the epidemic.

Painful diabetic neuropathy (PDN) is one of several clinical syndromes in patients with diabetic peripheral neuropathy (DPN) and presents a major challenge for optimal management. The epidemiology of PDN has not been extensively studied. On the basis of available data, the prevalence of pain ranges from 10% to 20% in patients with diabetes and from 40% to 50% in those with diabetic neuropathy. Neuropathic pain can be disabling and devastating, with a significant impact on the patient's quality of life and associated healthcare cost. Pathophysiologic mechanisms underlying PDN are similar to other neuropathic pain disorders and broadly invoke peripheral and central sensitization. The natural course of PDN is variable, with the majority of patients experiencing spontaneous improvement and resolution of pain. Quantifying neuropathic pain is difficult, especially in clinical practice, but has improved recently in clinical trials with the development of neuropathic pain-specific tools, such as the Neuropathic Pain Questionnaire and the Neuropathic Pain Symptom Inventory. Hyperglycemia-induced pathways result in nerve dysfunction and damage, which lead to hyperexcitable peripheral and central pathways of pain. Glycemic control may prevent or partially reverse DPN and modulate PDN.

Diabetes Mellitus (DM) is one of the most prevalent metabolic disorders characterized by increased blood glucose levels and improper primary metabolism resulting from the defects in insulin secretion, insulin action, or both. It is one of the most common health problems worldwide, and the prevalence of this disease is rapidly increasing, leading to microvascular (retinopathy, neuropathy and nephropathy) and macrovascular (heart attack, stroke and peripheral vascular disease) complications (Umar et al., 2010). The number of individuals with diabetes is increasing due to population growth, aging, urbanization and increasing prevalence of obesity and physical inactivity. According to recent estimates, the greatest absolute increase in the number of patients with diabetes will be in India and the total number is projected to 79.4 million in 2030. It is expected that about 366 million are likely to be diabetic by the year 2030 (Rahman and Zaman, 1989). Medicinal plants are the main source of organic compounds such as polyphenols, tannins, alkaloids, carbohydrates, terpenoids, steroids and flavonoids. These organic compounds represent a source for the discovery and development of new types of antidiabetic molecules. Many compounds isolated from plant sources have been reported to show antidiabetic activity. The key messages summarize some recent information in the field of antidiabetic phytochemicals.

Diabetes and the ageing process independently increase the risk for cardiovascular disease (CVD). Since incidence of diabetes increases as people get older, the diabetic older adults represent the largest population of diabetic subjects. This group of patients would potentially be threatened by the development of CVD related to both ageing and diabetes. The relationship between CVD, ageing and diabetes is explained by the negative impact of these conditions on vascular function. Functional and clinical evidence supports the role of vascular inflammation induced by the ageing process and by diabetes in vascular impairment and CVD. Inflammatory mechanisms in both aged and diabetic vasculature include pro-inflammatory cytokines, vascular hyperactivation of nuclear factor-кB, increased expression of cyclooxygenase and inducible nitric oxide synthase, imbalanced expression of pro/anti-inflammatory microRNAs, and dysfunctional stress-response systems (sirtuins, Nrf2). In contrast, there are scarce data regarding the interaction of these mechanisms when ageing and diabetes co-exist and its impact on vascular function. Older diabetic animals and humans display higher vascular impairment and CVD risk than those either aged or diabetic, suggesting that chronic low-grade inflammation in ageing creates a vascular environment favouring the mechanisms of vascular damage driven by diabetes. Further research is needed to determine the specific inflammatory mechanisms responsible for exacerbated vascular impairment in older diabetic subjects in order to design effective therapeutic interventions to minimize the impact of vascular inflammation. This would help to prevent or delay CVD and the specific clinical manifestations (cognitive decline, frailty and disability) promoted by diabetes-induced vascular impairment in the elderly.

Although distinguishing features of masked hypertension in diabetics are well known, the significance of antihypertensive treatment on clinical practice decisions has not been fully explored. We analyzed 9691 subjects from the population-based 11-country International Database on Ambulatory Blood Pressure in Relation to Cardiovascular Outcomes. Prevalence of masked hypertension in untreated normotensive participants was higher (P<0.0001) among 229 diabetics (29.3%, n=67) than among 5486 nondiabetics (18.8%, n=1031). Over a median of 11.0 years of follow-up, the adjusted risk for a composite cardiovascular end point in untreated diabetic-masked hypertensives tended to be higher than in normotensives (hazard rate [HR], 1.96; 95% confidence interval [CI], 0.97–3.97; P=0.059), similar to untreated stage 1 hypertensives (HR, 1.07; CI, 0.58–1.98; P=0.82), but less than stage 2 hypertensives (HR, 0.53; CI, 0.29–0.99; P=0.048). In contrast, cardiovascular risk was not significantly different in antihypertensive-treated diabetic-masked hypertensives, as compared with the normotensive comparator group (HR, 1.13; CI, 0.54–2.35; P=0.75), stage 1 hypertensives (HR, 0.91; CI, 0.49–1.69; P=0.76), and stage 2 hypertensives (HR, 0.65; CI, 0.35–1.20; P=0.17). In the untreated diabetic-masked hypertensive population, mean conventional systolic/diastolic blood pressure was 129.2±8.0/76.0±7.3 mm Hg, and mean daytime systolic/diastolic blood pressure 141.5±9.1/83.7±6.5 mm Hg. In conclusion, masked hypertension occurred in 29% of untreated diabetics, had comparable cardiovascular risk as stage 1 hypertension, and would require considerable reduction in conventional blood pressure to reach daytime ambulatory treatment goal. Importantly, many hypertensive diabetics when receiving antihypertensive therapy can present with normalized conventional and elevated ambulatory blood pressure that mimics masked hypertension.

To assess the feasibility and acceptability of a diabetes education program tailored to patients with type 2 diabetes in communities and the preliminary outcomes of the intervention. Methods: Two-phase, one group, mixed-method study design was used. Modified American Association of Diabetes Educators (AADE) diabetes education curriculum was used as the framework for the program. Patients with diabetes participated in classes and diabetes conversation map discussion. Feasibility and acceptability of the program were evaluated by the ability to recruit and retain participants and their satisfaction with the program. Diabetes knowledge test and the summary of diabetes self-care activities (SDSCA) were used to evaluate the knowledge and behavior changes of the patients. Results: 40 patients completed the program and the attrition rate was 11.1%. All participants were “very satisfied” with the program. Significant improvement in diabetes knowledge and blood glucose monitoring and foot care were reported. Conclusion: The diabetes education program based on modified AADE diabetes education curriculum combined with diabetes conversation map may be effective in patients with type 2 diabetes. Practice Implications: Flexible time schedule and a control group should be designed in the future study. PMID:24753774

Diabetic nephropathy accounts for the most serious microvascular complication of diabetes mellitus. It is suggested that the prevalence of diabetic nephropathy will continue to increase in future posing a major challenge to the healthcare system resulting in increased morbidity and mortality. It occurs as a result of interaction between both genetic and environmental factors in individuals with both type 1 and type 2 diabetes. Genetic susceptibility has been proposed as an important factor for the development and progression of diabetic nephropathy, and various research efforts are being executed worldwide to identify the susceptibility gene for diabetic nephropathy. Numerous single nucleotide polymorphisms have been found in various genes giving rise to various gene variants which have been found to play a major role in genetic susceptibility to diabetic nephropathy. The risk of developing diabetic nephropathy is increased several times by inheriting risk alleles at susceptibility loci of various genes like ACE, IL, TNF-α, COL4A1, eNOS, SOD2, APOE, GLUT, etc. The identification of these genetic variants at a biomarker level could thus, allow the detection of those individuals at high risk for diabetic nephropathy which could thus help in the treatment, diagnosis and early prevention of the disease. The present review discusses about the various gene variants found till date to be associated with diabetic nephropathy.

Diabetes mellitus is one of the most common chronic diseases in nearly all countries. It has been associated with sexual dysfunction, both in males and in females. Diabetes is an established risk factor for sexual dysfunction in men, as a threefold increased risk of erectile dysfunction was documented in diabetic men, as compared with nondiabetic men. Among women, evidence regarding the association between diabetes and sexual dysfunction are less conclusive, although most studies have reported a higher prevalence of female sexual dysfunction in diabetic women as compared with nondiabetic women. Female sexual function appears to be more related to social and psychological components than to the physiological consequence of diabetes. Hyperglycemia, which is a main determinant of vascular and microvascular diabetic complications, may participate in the pathogenetic mechanisms of sexual dysfunction in diabetes. Moreover, diabetic people may present several clinical conditions, including hypertension, overweight and obesity, metabolic syndrome, cigarette smoking, and atherogenic dyslipidemia, which are themselves risk factors for sexual dysfunction, both in men and in women. The adoption of healthy lifestyles may reduce insulin resistance, endothelial dysfunction, and oxidative stress – all of which are desirable achievements in diabetic patients. Improved well-being may further contribute to reduce and prevent sexual dysfunction in both sexes. PMID:24623985

Several abnormalities of the respiratory function have been reported in patients with type 1 and type 2 diabetes. These abnormalities concern lung volume, pulmonary diffusing capacity, control of ventilation, bronchomotor tone, and neuroadrenergic bronchial innervation. Many hypotheses have emerged, and characteristic histological changes have been described in the "diabetic lung", which could explain this abnormal respiratory function. Given the specific abnormalities in diabetic patients, the lung could thus be considered as a target organ in diabetes. Although the practical implications of these functional changes are mild, the presence of an associated acute or chronic pulmonary and/or cardiac disease could determine severe respiratory derangements in diabetic patients. Another clinical consequence of the pulmonary involvement in diabetes is the accelerated decline in respiratory function. The rate of decline in respiratory function in diabetics has been found to be two-to-three times faster than in normal non-smoking subjects, as reported in longitudinal studies. This finding, together with the presence of anatomical and biological changes similar to those described in the aging lung, indicates that the "diabetic lung" could even be considered a model of accelerated aging. This review describes and analyses the current insight into the relationship of diabetes and lung disease, and suggests intensifying research into the lung as a possible target organ in diabetes.

Background and objectives: There is evidence that the incidence of solid tumors is markedly increased in patients with diabetes mellitus. In the current study, we investigate the association between diabetes and renal cancer. Patients and Methods: A single-center retrospective analysis of 473 patients who underwent nephrectomy for renal cell carcinoma (RCC) was performed. Diabetic RCC patients were screened for age, gender, ethnicity, HgA1C, glucose levels and renal function. Results: Of the 473 cases with RCC, we identified 120 patients (25.4%) with a history of diabetes. The incidence of diabetes in RCC patients was higher in female than male subjects and in Hispanic compared to White and Other ethnic backgrounds. At diagnosis, the majority of diabetic RCC patients were 50-59 years of age. In diabetic RCC cases, clear cell type histology (92.0%), nuclear grade 2 (56.1%) and tumor size range from 1-5 cm (65.7%) were the most common in each category. Conclusion: Our findings indicate that diabetic RCC patients have a predominance of localized, small clear cell RCC. In addition, females with a history of RCC have a higher frequency of diabetes compared to males. This is the first report of clinical and histopathological features of RCC associated with diabetes.

Diabetes is characterized by increased fracture risk and by reduced bone strength for a given density. Contributing factors may include lower bone turnover and accumulation of advanced glycation endproducts. There are concerns that the pharmacological therapies for osteoporosis, particularly anti-resorptive therapies that suppress bone turnover, may not be as effective in the setting of diabetes. This review considers clinical trials and observational studies that have assessed the efficacy of anti-resorptive and anabolic therapies in diabetic patients. Post hoc analyses of randomized trials indicate that raloxifene has similar efficacy for prevention of vertebral fractures in diabetic compared with non-diabetic patients. Evidence from randomized clinical trials is lacking for anti-fracture efficacy of other osteoporosis therapies in diabetes. However, observational studies suggest that bisphosphonates are effective in preventing fractures in diabetic patients. The great majority of diabetic patients in studies to date have been type 2, and efficacy of osteoporosis therapies in type 1 diabetic patients remains to be addressed. Further evaluation of the efficacy of osteoporosis therapies in the setting of diabetes is needed to provide optimal fracture prevention for this population.
Recent census figures in Turkey show that out of a population of 76.6 million, 22.7 million (29.7%) are younger than 18 years old. The great majority (>95%) of pediatric cases of diabetes in Turkey are type 1 diabetes mellitus (T1DM). In recent years, with increase in number of pediatric endocrine centers around the country, the important issue of care for diabetic children and adolescents has been revived and major steps have been taken for improvement in pediatric care and its outreach to all diabetic children. The Childhood Diabetes Group continues its activities in cooperation with the Turkish Ministry of Health. A list of areas of interest of the Group include “School programs”, “Incidence/prevalence studies and national registry system”, “Educational guidelines for diabetes in children”, “Increasing the numbers of camps and summer schools for diabetic children”, “Organization of educational programs for the health team”, “National guidelines for transition of diabetic children to adult clinics”, “Improvement of school canteens”, “Educational spots” to improve awareness of diabetes. The activities of the Childhood Diabetes Group will be discussed in detail in this article. PMID:25800469

Background: Diabetes has a high prevalence in Iran, and its incidence is estimated to increase from 3.5 million adults in 2005 to 5.1 million by 2025. Given the high prevalence of diabetes in Iranians, it is surprising that little is known about understanding of diabetes in the general population. This study aimed to explore how people without diabetes interpreted the disease. Materials and Methods: This study was conducted as a qualitative content analysis, using unstructured and in-depth interviews, with the participation of 21 individuals without diabetes (13 women and 8 men), 18-61 years old, who were selected for this purpose from the cities of Isfahan and Tehran from October 2010 to May 2011. The data were analyzed using latent content analysis method. Results: The participants had different beliefs and ideas about diabetes and most of them gave a negative and black image of diabetes. Although a small number of individuals considered diabetes better than AIDS and cancer, they often took diabetes as blackness, end of romances, and a gradual death. Conclusion: However, the study sample was small. The findings show that the participants’ perspective on diabetes is negative and destructive. It seems shaping a new identity in the path of empowerment could be difficult within the social and cultural context. These findings can give an insight to health care providers to realize how important it is to find the public perception about diabetes. They are responsible to change or modify the public view on diabetes by introducing the disease with the help of prominent people and educating individuals in the society on all aspects of living with diabetes, not simply the symptoms and disabilities it brings along.

Diabetic nephropathy is a serious complication of diabetes and the leading cause of end-stage renal disease. Studies indicate both environmental and genetic factors contribute to the development and progression of diabetic nephropathy. In particular, epidemiological evidence shows a familial clustering of nephropathy in siblings with diabetes, supporting an important role of genetic susceptibility in the pathogenesis of diabetic nephropathy. A common approach in genetic research is assessment of candidate gene polymorphisms using case-control analysis; a number of studies have evaluated predictable candidate genes for diabetic nephropathy. In contrast, only a few studies have used a whole genome approach, such as scanning of micro-satellite markers, in the assessment of genetic susceptibility to diabetic nephropathy. A whole genome linkage analysis using families of Pima Indians showed susceptibility loci for diabetic nephropathy on chromosome 3, 7, and 20. Another linkage analysis using discordant sib-pairs of Caucasian families with type 1 diabetes identified a critical area on chromosome 3q. However, these results have been inconclusive and further investigation is required. Recently, a genome-wide, case-control analysis identifying susceptibility genes for diabetic nephropathy was performed. As a result, a single nucleotide polymorphism in exon 23 of the solute carrier family 12 (sodium-chloride cotransporter) member 3 gene was found to be strongly associated with diabetic nephropathy. Although further assessment of this polymorphism is needed, this strategy offers great promise in the identification of genetic factors predisposing patients to diabetic nephropathy. Identification of genetic susceptibility markers may offer new hope in the diagnosis and treatment of diabetic nephropathy.

Background Non-healing foot ulcers are the most common cause of non-traumatic amputation and hospitalization amongst diabetics in the developed world. Impaired wound neovascularization perpetuates a cycle of dysfunctional tissue repair and regeneration. Evidence implicates defective mobilization of marrow-derived progenitor cells (PCs) as a fundamental cause of impaired diabetic neovascularization. Currently, there are no FDA-approved therapies to address this defect. Here we report an endogenous PC strategy to improve diabetic wound neovascularization and closure through a combination therapy of AMD3100, which mobilizes marrow-derived PCs by competitively binding to the cell surface CXCR4 receptor, and PDGF-BB, which is a protein known to enhance cell growth, progenitor cell migration and angiogenesis. Methods and Results Wounded mice were assigned to 1 of 5 experimental arms (n = 8/arm): saline treated wild-type, saline treated diabetic, AMD3100 treated diabetic, PDGF-BB treated diabetic, and AMD3100/PDGF-BB treated diabetic. Circulating PC number and wound vascularity were analyzed for each group (n = 8/group). Cellular function was assessed in the presence of AMD3100. Using a validated preclinical model of type II diabetic wound healing, we show that AMD3100 therapy (10 mg/kg; i.p. daily) alone can rescue diabetes-specific defects in PC mobilization, but cannot restore normal wound neovascularization. Through further investigation, we demonstrate an acquired trafficking-defect within AMD3100-treated diabetic PCs that can be rescued by PDGF-BB (2 μg; topical) supplementation within the wound environment. Finally, we determine that combination therapy restores diabetic wound neovascularization and accelerates time to wound closure by 40%. Conclusions Combination AMD3100 and PDGF-BB therapy synergistically improves BM PC mobilization and trafficking, resulting in significantly improved diabetic wound closure and neovascularization. The success of this

Boundaries between monogenic and complex genetic diseases are becoming increasingly blurred, as a result of better understanding of phenotypes and their genetic determinants. This had a large impact on the way complex disease genetics is now being investigated. Starting with conventional approaches like familial linkage, positional cloning and candidate genes strategies, the scope of complex disease genetics has grown exponentially with scientific and technological advances in recent times. Despite identification of multiple loci harboring common and rare variants associated with complex diseases, interpreting and evaluating their functional role has proven to be difficult. Information from monogenic diseases, especially related to the intermediate traits associated with complex diseases comes handy. The significant overlap between traits and phenotypes of monogenic diseases with related complex diseases provides a platform to understand the disease biology better. In this review, we would discuss about one such complex disease, type 2 diabetes, which shares marked similarity of intermediate traits with different forms of monogenic diabetes.
GDM develops in 1-3% of all pregnancies. Women with GDM are characterized by a relatively diminished insulin secretion coupled with a pregnancy-induced insulin resistance primary located in skeletal muscle tissue. The cellular background for this insulin resistance is not known. The binding of insulin to its receptor and the subsequent activation of the insulin receptor tyrosine kinase have significant importance for the cellular effect of insulin. Thus, the pathogenesis to the insulin resistance was studied by investigating insulin receptor binding and tyrosine kinase activity in skeletal muscle biopsies from women with GDM and pregnant controls. No major abnormalities were found in GDM wherefore it is likely that the insulin resistance is caused by intracellular defects distal to the activation of the tyrosine kinase. Glucose tolerance returns to normal postpartum in the majority of women with GDM. However, previous studies, in populations quite different from a Danish population, have shown that women with previous GDM have a high risk of developing overt diabetes mellitus later in life. Hence, we aimed to investigate the prognosis of women with previous GDM with respect to subsequent development of diabetes and also to identify predictive factors for the development of overt diabets in these women. A follow-up study of diet treated GDM women diagnosed during 1978 to 1985 at the Rigshospital, Copenhagen was performed. Glucose tolerance was evaluated in 241 women (81% of the GDM population) 2-11 years after pregnancy. Abnormal glucose tolerance was found in 34.4% of the women (3.7% IDDM, 13.7% NIDDM, 17% IGT) in contrast to a control group where none had diabetes and 5.3% had IGT. Logistic regression analysis identified the following independent risk factors for later development of diabetes: a high fasting glucose level at diagnosis of GDM, a delivery more than 3 weeks before term, and an abnormal OGTT 2 months postpartum. Low insulin secretion at diagnosis of
