To investigate the association between nonadherence to diabetes treatment and the occurrence of diabetes complications. Our study retrospectively identified adherence and nonadherence to diabetes treatment in patients during the first year of observation after new diagnoses of type 2 diabetes enrolled in commercial database from 52 health insurers in Japan. Participants were insurance enrollees with type 2 diabetes who received healthcare between 2005 and 2013, and who could be tracked for more than 12months from the initiation of diabetes treatment. We compared the occurrence of diabetes-related complications (retinopathy, nephropathy, neuropathy, ischemic heart disease, cerebrovascular disease, and chronic arterial occlusion) and all-cause healthcare expenditure during the second to eighth years. We identified 1784 nonadherent patients and 9547 adherent patients. Cox proportional hazard models showed that the occurrence of microvascular complications was significantly higher in the nonadherent group: the hazard ratios (95% confidence intervals) for retinopathy, nephropathy, and neuropathy were 2.04 (1.57-2.66), 1.91 (1.35-2.72), and 1.83 (1.02-3.27), respectively. However, no significant differences were observed between the adherent and nonadherent groups for the macrovascular complications (ischemic heart disease, cerebrovascular disease, and chronic arterial occlusion). In addition, the nonadherent group had a significantly higher cumulative healthcare expenditure than the adherent group during the second-to-fifth-year period (p=0.029) and the second-to-sixth-year period (p=0.009) after treatment initiation. Nonadherence in the first year of diabetes may increase the incidence of complications and result in higher expenditures for patients and payers. Copyright © 2016 Elsevier Ireland Ltd.

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

Risk factors for cardiovascular complications in Japanese patients with diabetes have not been fully elucidated. Our objective was to determine incidence of and risk factors for coronary heart disease (CHD) and stroke in Japanese diabetic patients. We conducted a prospective study at 59 hospitals throughout Japan. Patients included 940 men and 831 women with type 2 diabetes (mean age, 58.2 yr) without a history of cardiovascular complications who were followed for a median of 7.86 yr. This was an observational study. Incidence of CHD and stroke was evaluated. Incidences of CHD and stroke per 1000 person-years were 9.59 and 7.45, respectively, whereas those of myocardial and brain infarctions were 3.84 and 6.29, respectively. Multivariate Cox analysis revealed that the serum log-transformed triglyceride level was a potent and independent predictor of CHD [hazard ratio (HR) = 1.54; 95% confidence interval (CI) = 1.22-1.94 per 1 sd increase), comparable to low-density lipoprotein (LDL) cholesterol (HR = 1.49; 95% CI = 1.25-1.78 per 1 sd increase). Triglycerides and LDL cholesterol linearly and continuously increased CHD risk, and subjects in the top third for both had markedly high risks of CHD, and their effects were possibly additive. However, serum triglycerides worked independently of blood pressure levels. Systolic blood pressure was the only significant predictor for stroke except for age (HR = 1.31; 95% CI = 1.04-1.65, per 1 sd increase). In Japanese patients with type 2 diabetes, the serum triglyceride level was a leading predictor of CHD, comparable to LDL cholesterol. Because the serum triglyceride level is not a leading predictor of CHD in diabetic subjects in Western countries, ethnic group-specific strategies for prevention of diabetic macroangiopathy may be indicated.

Diabetic nephropathy, leading to end-stage renal disease, has a considerable impact on public health and the social economy. However, there are few national registries of diabetic nephropathy in Japan. The aims of this prospective cohort study are to obtain clinical data and urine samples for revising the clinical staging of diabetic nephropathy, and developing new diagnostic markers for early diabetic nephropathy. The Japanese Society of Nephrology established a nationwide, web-based, and prospective registry system. On the system, there are two basic registries; the Japan Renal Biopsy Registry (JRBR), and the Japan Kidney Disease Registry (JKDR). In addition to the two basic registries, we established a new prospective registry to the system; the Japan Diabetic Nephropathy Cohort Study (JDNCS), which collected physical and laboratory data. We analyzed the data of 321 participants (106 female, 215 male; average age 65 years) in the JDNCS. Systolic and diastolic blood pressure was 130.1 and 72.3 mmHg, respectively. Median estimated glomerular filtration rate (eGFR) was 33.3 ml/min/1.73 m(2). Proteinuria was 1.8 g/gCr, and serum levels of albumin were 3.6 g/dl. The majority of the JDNCS patients presented with preserved eGFR and low albuminuria or low eGFR and advanced proteinuria. In the JRBR and JKDR registries, 484 and 125 participants, respectively, were enrolled as having diabetes mellitus. In comparison with the JRBR and JKDR registries, the JDNCS was characterized by diabetic patients presenting with low proteinuria with moderately preserved eGFR. There are few national registries of diabetic nephropathy to evaluate prognosis in Japan. Future analysis of the JDNCS will provide clinical insights into the epidemiology and renal and cardiovascular outcomes of type 2 diabetic patients in Japan.

The purpose of this exploratory, descriptive, correlational study was to describe the perceived risk for diabetes complications among urban African American adults (18-75 years old) with type 2 diabetes and to explore the interrelationships among illness perception, well-being, perceptions of risk for diabetes complications, and selected physiologic measures of diabetes risk: hemoglobin A1C, blood pressure, and microalbuminuria. Urban African American adults with type 2 diabetes (N = 143) were recruited from 3 Chicago city public health clinics. They completed a demographic survey and 3 instruments: the Risk Perception Survey-Diabetes Mellitus, the 12-item Well-being Questionnaire, and the Revised Illness Perception Questionnaire. Physiologic measures included blood pressure, urine for microalbuminuria, and capillary blood for A1C. There was low perception of risk for diabetes complications, which was incongruent with the physiologic measures of risk. Less than 33% of participants saw themselves as being at high risk for developing any complications of diabetes, with the exception of vision problems (39%), despite the fact that physiologic measures of risk for diabetes complications were high in this sample. Risk perception was associated with well-being, perception of negative consequences, number of symptoms, and negative emotions related to diabetes. Risk perception was not in line with risk, as indicated by physiologic measures; thus, it is necessary to heighten this population's perception of risk for diabetes complications.

The Japan Diabetes Complications Study (JDCS), a nation-wide, multicenter, prospective study of patients with type 2 diabetes, reported that hemoglobin A 1c (HbA 1c ), systolic blood pressure, and smoking were risk factors for the onset of macroalbuminuria. This study explored the risk factors for glomerular filtration rate (GFR) decline in the JDCS patients. We examined the 1407 JDCS patients (667 women, mean age 59years, 974 normoalbuminuria, 433 microalbuminuria) whose urinary albumin-to-creatinine ratio (UACR) and estimated GFR (eGFR) were determined at baseline with an 8-year follow-up. We divided all the patients into four groups according to baseline eGFR: G1 (120≤eGFR), G2 (90≤eGFR<120), G3 (60≤eGFR<90), G4 (eGFR<60). The eGFRs in groups G1 and G2 decreased at follow-up compared to those at the baseline. The risk of annual eGFR decline rate≥3ml/min/1.73m 2 (rapid decliners) increased as the baseline eGFR increased. Advanced age, high HbA 1c , and UACR, or diabetic retinopathy at baseline were risk factors for the rapid decliners. Especially the G1 group had a significant risk for the rapid decliners. The frequency of the patients with GFR<60ml/min/1.73m 2 at the follow-up amounted to 31.1% in the rapid decliners, which was higher than 12% in the non-rapid decliners. In normo- and microalbuminuric patients with type 2 diabetes, extra careful attention should be paid to patients with eGFR ≥120ml/min/1.73m 2 to detect cases with rapidly decreased GFR under the normal range.

Long term hyperglycemia leads to development of complications associated with diabetes. Diabetic complications are now a global health problem without effective therapeutic approach. Hyperglycemia and oxidative stress are important components for the development of diabetic complications. Over the past few decades, herbal medicines have attracted much attention as potential therapeutic agents in the prevention and treatment of diabetic complications due to their multiple targets and less toxic side effects. This review aims to assess the current available knowledge of medicinal herbs for attenuation and management of diabetic complications and their underlying mechanisms. Bibliographic investigation was carried out by scrutinizing classical text books and peer reviewed papers, consulting worldwide accepted scientific databases (SCOPUS, PUBMED, SCIELO, NISCAIR, Google Scholar) to retrieve available published literature. The inclusion criteria for the selection of plants were based upon all medicinal herbs and their active compounds with attributed potentials in relieving diabetic complications. Moreover, plants which have potential effect in ameliorating oxidative stress in diabetic animals have been included. Overall, 238 articles were reviewed for plant literature and out of the reviewed literature, 127 articles were selected for the study. Various medicinal plants/plant extracts containing flavonoids, alkaloids, phenolic compounds, terpenoids, saponins and phytosterol type chemical constituents were found to be effective in the management of diabetic complications. This effect might be attributed to amelioration of persistent hyperglycemia, oxidative stress and modulation of various metabolic pathways involved in the pathogenesis of diabetic complications. Screening chemical candidate from herbal medicine might be a promising approach for new drug discovery to treat the diabetic complications. There is still a dire need to explore the mechanism of action of

Much is written about how difficult it is to deal with diabetes during adolescence, and rightly so. Less is understood as to how puberty may be an accelerator of vascular complications. With the increase in childhood diabetes, complication risks need to be revisited in relation to puberty and the secular increase in adiposity. Recent data suggest greater risk for severe vascular complications in those with diabetes during puberty, compared with young people who develop diabetes after puberty. It is also widely recognized that higher hemoglobin A1c (HbA1c) results are often seen during the pubertal period. This article will review complication outcomes in relation to puberty and examine mechanisms by which puberty may modify risk above glycemic exposure, and possible gender disparities in the risk of complications in the adolescent period. © 2014 John Wiley & Sons A/S.

Oxidative stress and inflammation play critical roles in the development of diabetes and its complications. Recent studies provided compelling evidence that the newly discovered lipid signaling system (ie, the endocannabinoid system) may significantly influence reactive oxygen species production, inflammation, and subsequent tissue injury, in addition to its well-known metabolic effects and functions. The modulation of the activity of this system holds tremendous therapeutic potential in a wide range of diseases, ranging from cancer, pain, neurodegenerative, and cardiovascular diseases to obesity and metabolic syndrome, diabetes, and diabetic complications. This review focuses on the role of the endocannabinoid system in primary diabetes and its effects on various diabetic complications, such as diabetic cardiovascular dysfunction, nephropathy, retinopathy, and neuropathy, particularly highlighting the mechanisms beyond the metabolic consequences of the activation of the endocannabinoid system. The therapeutic potential of targeting the endocannabinoid system and certain plant-derived cannabinoids, such as cannabidiol and Δ9-tetrahydrocannabivarin, which are devoid of psychotropic effects and possess potent anti-inflammatory and/or antioxidant properties, in diabetes and diabetic complications is also discussed.

Lack of health insurance can adversely affect access to medical care which leads to poor disease outcome. Few studies examine the effects of no insurance on the development of diabetes complications. The objective of this study was to determine if there is an association between health insurance status and the outcome of complications among a group of diabetic patients admitted to a teaching hospital on the Texas-Mexico border. A retrospective case-control study was conducted over a one-year period. Multiple imputations were used to address missing values. We examined 82 diabetics who had one or more complications and 83 diabetic controls without complications. A complication was defined as a current skin or soft-tissue infection or a limb amputation. The main exposure was health insurance status, a three-level variable: no health insurance, Medicaid, and other insurance (referent). Logistic regression was used to calculate health insurance odds ratios (OR) adjusted for age, sex, and a history of recent trauma. Patients with no health insurance were twice as likely to have a diabetic complication as patients in the referent category: adjusted OR = 2.22, P = 0.03. An association between Medicaid status and complications was not detected (adjusted OR = 1.16, P = 0.78). Not having health insurance was a risk factor for developing diabetic complications in a group of predominantly Hispanic patients.

Role of crystallins in diabetic complications.

Crystallins are the major structural proteins of vertebrate eye lens responsible for maintaining the refractive index of the lens. However, recent studies suggest that they also have a functional significance in non-lenticular tissues. Prolonged uncontrolled diabetes results in the development of macro and microvascular complications that are the leading causes of morbidity and mortality in diabetic patients all over the world. Recent studies have shown that crystallins play an instrumental role in diabetes and its complications. Therefore, this review highlights the current data on the impact of chronic hyperglycemia on expression, distribution, glycation, phosphorylation, chaperone-like function and, anti-apoptotic activity of crystallins. Furthermore, we discussed the insights for developing therapeutic strategies for diabetic complications including natural agents, peptides, and pharmacological chaperones that modulate or mimic chaperone activity of α-crystallins. Upregulation of crystallins appears to be a common feature of chronic diabetes. Further, chronic hyperglycemia induces the glycation and phosphorylation of crystallins, mainly α-crystallins and thereby alters their properties. The disturbed interaction of αB-crystallin with various apoptotic mediators including Bax and caspases is also an important factor for increased cell death in diabetes. Numerous dietary agents, peptides, and chemical chaperones prevent apoptosis and the loss of chaperone activity in diabetes. Understanding the role of crystallins will aid in developing therapeutic strategies for alleviating pathophysiological conditions such as protein aggregation, inflammation, oxidative stress and apoptosis associated with chronic complications of diabetes including cataract, retinopathy, and cardiomyopathy.

Magnesium ion, as important cation in the human body, involved in various enzymatic reactions, glucose transport and insulin release. Now diabetes mellitus and diabetic complications have become important public health problems around the world. This paper explores the association between concentration levels of serum magnesium and common complications and comorbidities of diabetes mellitus and other biochemical indexes. There are 1217 eligible patients selected from 14,317 cases of diabetic hospitalization patients from January 2010 to December 2011. Random forest algorithm was applied to assess the importance of various biochemical indexes and to perform diabetic complications prediction. The research results showed that low concentration of serum magnesium and four common diabetic complications - diabetic retinopathy, diabetic nephropathy, diabetic neuropathy and diabetic macroangiopathy - exists association, but no obvious correlation with other comorbidities like hypertension. The specific factors of four common diabetic complications were selected from the biochemical indexes to provide a reference direction for further research.

Protein O-GlcNAcylation in diabetes and diabetic complications

2014-01-01

The post-translational modification of serine and threonine residues of proteins by O-linked β-N-acetylglucosamine (O-GlcNAc) is highly ubiquitous, dynamic and inducible. Protein O-GlcNAcylation serves as a key regulator of critical biological processes including transcription, translation, proteasomal degradation, signal transduction and apoptosis. Increased O-GlcNAcylation is directly linked to insulin resistance and to hyperglycemia-induced glucose toxicity, two hallmarks of diabetes and diabetic complications. In this review, we briefly summarize what is known about protein O-GlcNAcylation and nutrient metabolism, as well as discuss the commonly used tools to probe changes of O-GlcNAcylation in cultured cells and in animal models. We then focus on some key proteins modified by O-GlcNAc, which play crucial roles in the etiology and progression of diabetes and diabetic complications. Proteomic approaches are also highlighted to provide a system view of protein O-GlcNAcylation. Finally, we discuss how aberrant O-GlcNAcylation on certain proteins may be exploited to develop methods for the early diagnosis of pre-diabetes and/or diabetes. PMID:23992419

Preventing microvascular complications in type 1 diabetes mellitus

PubMed Central

Viswanathan, Vijay

2015-01-01

Patients with complications of diabetes such as retinopathy, nephropathy, and cardiovascular complications have increased hospital stay with greater economic burden. Prevention of complications should be started before the onset of type 1 diabetes mellitus (T1DM) by working on risk factors and thereafter by intervention upon confirmatory diagnosis which can prevent further damage to β-cells. The actual risk of getting microvascular complications like microalbuminuria and retinopathy progression starts at glycated hemoglobin (HbA1c) level of 7%. As per the American Diabetes Association, a new pediatric glycemic control target of HbA1c <7.5% across all ages replaces previous guidelines that had called for different targets by age. Evidence shows that prevalence of microvascular complications is greater in patients with age >20 years as compared to patients <10 years of age. Screening of these complications should be done regularly, and appropriate preventive strategies should be followed. Angiotensin converting enzyme inhibitors and angiotensin II receptor blocker reduce progression from microalbuminuria to macroalbuminuria and increase the regression rate to normoalbuminuria. Diabetic microvascular complications can be controlled with tight glycemic therapy, dyslipidemia management and blood pressure control along with renal function monitoring, lifestyle changes, including smoking cessation and low-protein diet. An integrated and personalized care would reduce the risk of development of microvascular complications in T1DM patients. The child with diabetes who receives limited care is more likely to develop long-term complications at an earlier age. Screening for subclinical complications and early interventions with intensive therapy is the need of the hour. PMID:25941647

Hypertension complicating diabetic pregnancies: pathophysiology, management, and controversies.

Sullivan, Shannon D; Umans, Jason G; Ratner, Robert

2011-04-01

Hypertensive disorders of pregnancy (HDP), including pre-existing hypertension, gestational hypertension, and preeclampsia, further complicate already high-risk pregnancies in women with diabetes mellitus (DM). Women with both pre-existing and gestational diabetes are at increased risk for HDP, leading to higher maternal and fetal morbidity. Further, particularly in diabetic women and women with a history of gestational diabetes, HDP significantly increases the risk for future cardiovascular events. For clinicians, women with hypertension and diabetes during pregnancy pose a management challenge. Specifically, preconception management should stress strict control of glycemia, blood pressure, and prevention of diabetic complications, specifically nephropathy, which specifically increases the risk for preeclampsia. During gestation, clinicians must be aware of potential maternal and fetal complications associated with various anti-hypertensive therapies, including known fetotoxicity of ACE inhibitors and ARBs when given in the 2nd or 3rd trimester, and the risks and benefits of expectant management versus delivery in cases of severe gestational hypertension or preeclampsia. Indeed, diabetic women must be followed closely prior to conception and throughout gestation to minimize the risk of HDP and its associated complications. © 2011 Wiley Periodicals, Inc.

Objective We introduced a new information technology-based diabetes management system, called the Internet-based glucose monitoring system (IBGMS), and demonstrated its short-term and long-term favorable effects. However, there has been no report on clinical effects of such a new diabetes management system on the development of diabetic complications so far. This study was used to simulate the complication reducing effect of the IBGMS, given in addition to existing treatments in patients with type 2 diabetes. Research Design and Methods The CORE Diabetes Model, a peer-reviewed, published, validated computer simulation model, was used to project long-term clinical outcomes in type 2 diabetes patients receiving the IBGMS in addition to their existing treatment. The model combined standard Markov submodels to simulate the incidence and progression of diabetes-related complications. Results The addition of IBGMS was associated with improvements in reducing diabetic complications, mainly microangiopathic complications, including diabetic retinopathy, diabetic neuropathy, diabetic nephropathy, and diabetic foot ulcer. The IBGMS also delayed the development of all diabetic complications for more than 1 year. Conclusions This study demonstrated that the simulated IBGMS, compared to existing treatment, was associated with a reduction of diabetic complications. As a result, it provides valuable evidence for practical application to the public in the world. PMID:19885180

The increasing prevalence of diabetes in South Asians has significant health and economic implications. South Asians are predisposed to the development of diabetes due to biologic and lifestyle factors. Furthermore, they experience significant morbidity and mortality from complications of diabetes, most notably coronary artery disease, cerebrovascular disease and chronic kidney disease. Therefore, understanding the pathophysiology and genetics of diabetes risk factors and its associated complications in South Asians is paramount to curbing the diabetes epidemic. With this understanding, the appropriate screening, preventative and therapeutic strategies can be implemented and further developed. In this review, we discuss in detail the biologic and lifestyle factors that predispose South Asians to diabetes and review the epidemiology and pathophysiology of microvascular and macrovascular complications of diabetes in South Asians. We also review the ongoing and completed diabetes prevention and management studies in South Asians. PMID:24643902

An increase in the rates of morbidity and mortality associated with diabetic complications is a global concern. Glycemic control is important to prevent the development and progression of diabetic complications. Various classes of anti-diabetic agents are currently available, and their pleiotropic effects on diabetic complications have been investigated. Incretin-based therapies such as dipeptidyl peptidase (DPP)-4 inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RA) are now widely used in the treatment of patients with type 2 diabetes. A series of experimental studies showed that incretin-based therapies have beneficial effects on diabetic complications, independent of their glucose-lowering abilities, which are mediated by anti-inflammatory and anti-oxidative stress properties. Based on these findings, clinical studies to assess the effects of DPP-4 inhibitors and GLP-1RA on diabetic microvascular and macrovascular complications have been performed. Several but not all studies have provided evidence to support the beneficial effects of incretin-based therapies on diabetic complications in patients with type 2 diabetes. We herein discuss the experimental and clinical evidence of incretin-based therapy for diabetic complications. PMID:27483245

The purpose of this study was to identify and report the complications associated with the use of circular ring fixation in diabetic patients, and to compare the frequency of complications in patients without diabetes. We hypothesized that complications with circular ring fixation occurred more frequently in patients with diabetes than patients without diabetes. Institutional Review Board approval was obtained and patient charts were retrospectively reviewed from June 2004 and February 2007. Fifty six consecutive patients undergoing midfoot, hindfoot and/or ankle surgery were treated with circular ring fixation which included 33 diabetic patients in the study group and 23 non-diabetic patients in the control group. Patient demographics, the duration of treatment with the external fixator, and complications were recorded. Males had a greater number of complications compared to females (p = 0.0014). The total number of complications was statistically greater in diabetic patients (study group) versus non-diabetic patients (control group) (p = 0.003). In multivariate logistic regression, diabetes and male sex were the only significant variables associated with wire complications (OR 7.35, 95% CI 1.93-28.04 and OR 0.22, 95% CI 0.05-8584111, respectively). Women are protected from wire complications with a risk reduction of 78% compared to males. Diabetics have a 7-fold risk for any wire complication compared to patients without diabetes. We found no adverse effects of BMI, obesity, age, smoking, neuropathy, or Charcot neuroarthropathy on a satisfactory recovery.

We also review the ongoing and completed diabetes prevention and management studies in South Asians.

Microvascular complications and the diabetic pregnancy.

Without strict glycemic control, diabetic pregnancies are frequently complicated by spontaneous abortion, stillbirth, or congenital malformation. Retrospective studies have been largely reassuring that pregnancy does not accelerate morbid outcomes in women with diabetic vascular disease. Improved outcomes of high-risk pregnancy in women with pregestational, type 1, or type 2 diabetes mellitus remain challenging, depending on a comprehensive and multidisciplinary team approach and extensive preconception counseling.

Context Diabetes is a global health challenge. Although large prospective clinical trials have shown that intensive control of blood glucose or blood pressure reduces the risk for development and progression of vascular complications in diabetes, a substantial number of diabetic patients still experience renal failure and cardiovascular events, which could account for disabilities and high mortality rate in these subjects. Objective Sulphoraphane is a naturally occurring isothiocyanate found in widely consumed cruciferous vegetables, such as broccoli, cabbage and Brussels sprouts, and an inducer of phase II antioxidant and detoxification enzymes with anticancer properties. We reviewed here the protective role of sulphoraphane against diabetic vascular complications. Methods In this review, literature searches were undertaken in Medline and in CrossRef. Non-English language articles were excluded. Keywords [sulphoraphane and (diabetes, diabetic nephropathy, diabetic retinopathy, diabetic neuropathy, diabetic complications, vascular, cardiomyocytes, heart or glycation)] have been used to select the articles. Results There is accumulating evidence that sulphoraphane exerts beneficial effects on vascular damage in both cell culture and diabetic animal models via antioxidative properties. Furthermore, we have recently found that sulphoraphane inhibits in vitro formation of advanced glycation end products (AGEs), suppresses the AGE-induced inflammatory reactions in rat aorta by reducing receptor for AGEs (RAGE) expression and decreases serum levels of AGEs in humans. Conclusion These findings suggest that blockade of oxidative stress and/or the AGE-RAGE axis by sulphoraphane may be a novel therapeutic strategy for preventing vascular complications in diabetes.

To determine which barriers to care are associated with type 2 diabetes complications in an area in rural East England. 3649 individuals with type 2 diabetes from 62 general practices were contacted via postal invitation which included a 33 item Barriers-to-Diabetes-Care Survey. Barriers were grouped into five priori major categories: educational, physical, psychological, psychosocial, and systems. The associations of reported barriers, both individually and as a group, with self-reported complications were assessed using logistic regression. 39.5% of participants had self-reported diabetes complications. Physical health barriers (OR = 3.3; 95%CI: 2.7, 4.0), systems barriers (OR = 1.6; 95%CI: 1.3, 2.0) and psychological barriers (OR = 1.3 (95%CI: 1.1, 1.5) were associated with diabetes complications. In subcategories, presence of comorbidities (OR = 4.8; 95%CI: 3.9, 5.9), financial difficulties (OR = 1.7; 95%CI: 1.3, 2.1), absence of services (OR = 2.0; 95%CI: 1.4, 3.0), feeling others should bear more financial responsibility for their care (OR = 1.6 (95%CI: 1.1, 2.1), no access to diabetes service (OR = 1.3; 95%CI: 1.1, 1.5), feeling worried about their diabetes (OR = 1.5; 95%CI: 1.2, 2.0) and lack of readiness to exercise (OR = 1.4; 95%CI: 1.2, 1.7) were associated with diabetes complications. Barriers to self-care are significantly more common among those with, than those without, diabetes complications. Systematic identification and management of different barriers to self-care could help personalise care for those with diabetes related complications. Copyright © 2018 Elsevier B.V.

Diabetes mellitus (DM), an endocrine disorder, will be one of the leading causes of death world-wide in about two decades. Cellular injuries and disorders of energy metabolism are two key factors in the pathogenesis of diabetes, which also become the important causes for the process of diabetic complications. AMPK is a key enzyme in maintaining metabolic homeostasis and has been implicated in the activation of autophagy in distinct tissues. An increasing number of researchers have confirmed that autophagy is a potential factor to affect or induce diabetes and its complications nowadays, which could remove cytotoxic proteins and dysfunctional organelles. This review will summarize the regulation of autophagy and AMPK in diabetes and its complications, and explore how AMPK stimulates autophagy in different diabetic syndromes. A deeper understanding of the regulation and activity of AMPK in autophagy would enhance its development as a promising therapeutic target for diabetes treatment. PMID:26904395

OBJECTIVE The development of periarticular thickening of skin on the hands and limited joint mobility (cheiroarthropathy) is associated with diabetes and can lead to significant disability. The objective of this study was to describe the prevalence of cheiroarthropathy in the well-characterized Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) cohort and examine associated risk factors, microvascular complications, and the effect of former DCCT therapy (intensive [INT] vs. conventional [CONV]) on its development. RESEARCH DESIGN AND METHODS This cross-sectional analysis was performed in 1,217 participants (95% of the active cohort) in EDIC years 18/19 after an average of 24 years of follow-up. Cheiroarthropathy—defined as the presence of any one of the following: adhesive capsulitis, carpal tunnel syndrome, flexor tenosynovitis, Dupuytren's contracture, or a positive prayer sign—was assessed using a targeted medical history and standardized physical examination. A self-administered questionnaire (Disabilities of the Arm, Shoulder and Hand [DASH]) assessed functional disability. RESULTS Cheiroarthropathy was present in 66% of subjects (64% of the INT group and 68% of the CONV group; P = 0.1640) and was associated with age, sex, diabetes duration, skin intrinsic fluorescence, HbA1c, neuropathy, and retinopathy (P < 0.005 for each). DASH functional disability scores were worse among subjects with cheiroarthropathy (P < 0.0001). CONCLUSIONS Cheiroarthropathy is common in people with type 1 diabetes of long duration (∼30 years) and is related to longer duration and higher levels of glycemia. Clinicians should include cheiroarthropathy in their routine history and physical examination of patients with type 1 diabetes because it causes clinically significant functional disability.

Diabetes mellitus (DM) is a metabolic disease defined by elevated blood glucose (BG). DM is a global epidemic and the prevalence is anticipated to continue to increase. The ocular complications of DM negatively impact the quality of life and carry an extremely high economic burden. While systemic control of BG can slow the ocular complications they cannot stop them, especially if clinical symptoms are already present. With the advances in biodegradable polymers, implantable ocular devices can slowly release medication to stop, and in some cases reverse, diabetic complications in the eye. In this review we discuss the ocular complications associated with DM, the treatments available with a focus on localized treatments, and what promising treatments are on the horizon. PMID:27119078

2008-03-01

Ankle fractures in patients with diabetes mellitus have long been recognized as a challenge to practicing clinicians. Complications of impaired wound healing, infection, malunion, delayed union, nonunion, and Charcot arthropathy are prevalent in this patient population. Controversy exists as to whether diabetic ankle fractures are best treated noninvasively or by open reduction and internal fixation. Patients with diabetes are at significant risk for soft-tissue complications. In addition, diabetic ankle fractures heal, but significant delays in bone healing exist. Also, Charcot ankle arthropathy occurs more commonly in patients who were initially undiagnosed and had a delay in immobilization and in patients treated nonsurgically for displaced ankle fractures. Several techniques have been described to minimize complications associated with diabetic ankle fractures (eg, rigid external fixation, use of Kirschner wires or Steinmann pins to increase rigidity). Regardless of the specifics of treatment, adherence to the basic principles of preoperative planning, meticulous soft-tissue management, and attention to stable, rigid fixation with prolonged, protected immobilization are paramount in minimizing problems and yielding good functional outcomes.

Circulating levels of N-terminal fragment of probrain natriuretic peptide (NT-proBNP) are established as a risk factor for cardiovascular disease and mortality in patients with diabetes, as well as in the general population. We sought to examine the possibility of NT-proBNP as a biomarker of microvascular complications in patients with type 2 diabetes. In total, 277 outpatients with type 2 diabetes were consecutively enrolled as a hospital cohort. Two hundred and seventeen of these patients (132 males; mean age, 63.4 years) were designated as cases with any of the diabetic complications (retinopathy, neuropathy, nephropathy, ischemic heart disease, strokes, peripheral artery disease), and 60 (42 males; mean age, 54.1 years) were set as controls without clinical evidence of diabetic complications. Diabetic complications were evaluated by medical record and routine laboratory examinations. NT-proBNP was measured and investigated with regard to the associations with diabetic complications. Mean NT-proBNP levels were significantly higher in patients with any of the diabetic complications (59 versus 33 pg/mL; P<0.0001). In logistic regression analysis, NT-proBNP levels >79 pg/mL, which was the highest tertile, were independently associated with a 5.04 fold increased risk of all complications (P<0.0051) compared to the lowest tertile (NT-proBNP levels <31 pg/mL). Odd ratios of cardiovascular disease and nephropathy, neuropathy, and retinopathy were 9.33, 6.23, 6.6 and 13.78 respectively, in patients with NT-proBNP values in the highest tertile (>79 pg/mL), independently of age, sex, duration of diabetes or other risk factors, such as body mass index or hemoglobin A1c. In addition, NT-proBNP levels were associated with surrogate markers of atherosclerosis, such as brachial-ankle pulse wave velocity (r=0.449, P<0.0001) and left ventricular hypertrophy (r=0.212, P<0.001). In this hospital-based cohort of type 2 diabetes, the NT-proBNP levels were associated with systemic

The Spontaneously Diabetic Torii (SDT) rat is an inbred strain of Sprague-Dawley rat and recently is established as a nonobese model of type 2 diabetes (T2D). Male SDT rats show high plasma glucose levels (over 700 mg/dL) by 20 weeks. Male SDT rats show pancreatic islet histopathology, including hemorrhage in pancreatic islets and inflammatory cell infiltration with fibroblasts. Prior to the onset of diabetes, glucose intolerance with hypoinsulinemia is also observed. As a result of chronic severe hyperglycemia, the SDT rats develop profound complications. In eyes, retinopathy, cataract, and neovascular glaucoma are observed. Proliferative retinopathy, especially, resulting from retinal neovascular vessels is a unique characteristic of this model. In kidney, mesangial proliferation and nodular lesion are observed. Both peripheral neuropathy such as decreased nerve conduction velocity and thermal hypoalgesia and autonomic neuropathy such as diabetic diarrhea and voiding dysfunction have been reported. Osteoporosis is another complication characterized in SDT rat. Decreased bone density and low-turnover bone lesions are observed. Taking advantage of these features, SDT rat has been used for evaluating antidiabetic drugs and drugs/gene therapy for diabetic complications. In conclusion, the SDT rat is potentially a useful T2D model for studies on pathogenesis and treatment of diabetic complications in humans. PMID:23691526

Advanced Glycation End Products and Diabetic Complications

PubMed Central

Singh, Varun Parkash; Bali, Anjana; Singh, Nirmal

2014-01-01

During long standing hyperglycaemic state in diabetes mellitus, glucose forms covalent adducts with the plasma proteins through a non-enzymatic process known as glycation. Protein glycation and formation of advanced glycation end products (AGEs) play an important role in the pathogenesis of diabetic complications like retinopathy, nephropathy, neuropathy, cardiomyopathy along with some other diseases such as rheumatoid arthritis, osteoporosis and aging. Glycation of proteins interferes with their normal functions by disrupting molecular conformation, altering enzymatic activity, and interfering with receptor functioning. AGEs form intra- and extracellular cross linking not only with proteins, but with some other endogenous key molecules including lipids and nucleic acids to contribute in the development of diabetic complications. Recent studies suggest that AGEs interact with plasma membrane localized receptors for AGEs (RAGE) to alter intracellular signaling, gene expression, release of pro-inflammatory molecules and free radicals. The present review discusses the glycation of plasma proteins such as albumin, fibrinogen, globulins and collagen to form different types of AGEs. Furthermore, the role of AGEs in the pathogenesis of diabetic complications including retinopathy, cataract, neuropathy, nephropathy and cardiomyopathy is also discussed. PMID:24634591

Vitamin D and Diabetic Complications: True or False Prophet?

Vitamin D deficiency is now recognized as a condition of increasing prevalence worldwide. Vitamin D has an established role in calcium and bone metabolism; however, more recently associations with vitamin D deficiency and risk of developing diabetes, diabetes complications, and cardiovascular disease have all been acknowledged. The vitamin D receptor is ubiquitously expressed, and experimental, in vitro, and in vivo studies strongly suggest a role in regulating the transcription of multiple genes beyond calcium homeostasis. These include antiproliferative, immunomodulatory, angiogenic, inhibition of the renin-angiotensin-aldosterone system, and neurotrophic factor expression. Observational studies report a strong association between vitamin D deficiency and cardiovascular and metabolic disorders; however, there remains a paucity of large long-term randomized clinical trials showing a benefit with treatment. An increasing body of literature suggests a possible pathogenetic role of vitamin D in the long-term complications of diabetes and vitamin D deficiency may also exacerbate symptoms of painful diabetic peripheral neuropathy. It remains unknown if supplementation of vitamin D to normal or non-deficient levels alters pathogenetic processes related to diabetic microvascular complications. With the high prevalence of vitamin D deficiency in patients with diabetes and putative mechanisms linking vitamin D deficiency to diabetic complications, there is a compelling argument for undertaking large well-designed randomized controlled trials of vitamin D supplementation.

To investigate whether 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor (statin) use is associated with an increased risk of diabetes mellitus and hyperglycemia, we performed a nested case-control study using a postmarketing surveillance database in Japan. The database cohort included 26,849 cases of statin use and 5308 cases of other lipid-lowering drug use in patients with hyperlipidemia. Participants received at least 1 type of statin, had a clear medication history of statin use, and had no complications of diabetes mellitus. Cases were defined as onset of diabetes mellitus or hyperglycemia during statin intake. For each case, 20 controls were randomly selected and matched by time point. The factors associated with an increased risk of diabetes mellitus and hyperglycemia during statin intake examined included sex, age, body mass index, statin use duration, complications, concomitant medication, and clinical laboratory tests. Statin-associated diabetes mellitus or hyperglycemia was identified based on abnormal elevation of blood glucose concentrations beyond the reference range. A total of 19,868 patients met the inclusion criteria, of whom 24 were patients in the case group. Two complicating factors, fatty liver (adjusted odds ratio 16.10) and hyperuricemia (adjusted odds ratio 28.96), were extracted for onset of diabetes mellitus or hyperglycemia. Nonalcoholic fatty liver was associated with diabetes mellitus, obesity, and insulin resistance, and hyperuricemia was associated with lifestyle. This study suggested that the onset of diabetes mellitus or hyperglycemia might be increased with statin use in patients with complications of fatty liver and hyperuricemia. © 2018, The American College of Clinical Pharmacology.

The prevalence of both hypertension and diabetes mellitus is increasing worldwide. Both diseases lead to severe complications such as cardiovascular and chronic kidney diseases, which increase the risk of death over a long period of time. Therefore, the prevention and aggravation of hypertension and diabetes mellitus are major challenges. Because few review articles have focused on the epidemiological perspective of hypertension and diabetes mellitus, we reviewed major observational studies mainly from Japan and from Western countries that have reported on the prevalence of hypertension and diabetes mellitus, the binominal risk of hypertension and diabetes mellitus, and the risk of their coexistence. Our investigation found that approximately 50% of diabetic patients had hypertension, and approximately 20% of hypertensive patients had diabetes mellitus. Those with either hypertension or diabetes mellitus had a 1.5- to 2.0-fold higher risk of having both conditions. These results were similar for both Japan and Western countries. Although comparing the results between Japan and Western countries was difficult because the risks were estimated using widely varying statistical analyses, it was revealed that the coexistence of hypertension and diabetes mellitus certainly increased the risk of complications regardless of the country. The definition, prevalence and medical treatment of hypertension and diabetes mellitus will change in the future. For early intervention based on the latest evidence to prevent severe complications, it is important to accumulate epidemiological knowledge of hypertension and diabetes mellitus and to update the evidence for both Japan and other countries.

Type 2 Diabetes (T2D) is a chronic disease associated with a number of micro- and macrovascular complications that increase the morbidity and mortality of patients. The risk of diabetic complications has a strong genetic component. To this end, we sought to evaluate the association of 40 single nucleotide polymorphisms (SNPs) in 21 candidate genes with T2D and its vascular complications in 503 T2D patients and 580 healthy controls. The genes were chosen because previously reported to be associated with T2D complications and/or with the aging process. We replicated the association of T2D risk with I GF2BP rs4402960 and detected novel associations with TERT rs2735940 and rs2736098. The addition of these SNPs to a model including traditional risk factors slightly improved risk prediction. After stratification of patients according to the presence/absence of vascular complications, we found significant associations of variants in the CAT , FTO , and UCP1 genes with diabetic retinopathy and nephropathy. Additionally, a variant in the ADIPOQ gene was found associated with macrovascular complications. Notably, these genes are involved in some way in mitochondrial biology and reactive oxygen species regulation. Hence, our findings strongly suggest a potential link between mitochondrial oxidative homeostasis and individual predisposition to diabetic vascular complications.

Bioactive Compounds and Their Neuroprotective Effects in Diabetic Complications

Hyperglycemia, hyperlipidemia and impaired insulin signaling during the development of diabetes can cause diabetic complications, such as diabetic neuropathy, resulting in significant morbidity and mortality. Although various therapeutics are available for the treatment of diabetic neuropathy, no absolute cure exists, and additional research is necessary to comprehensively understand the underlying pathophysiological pathways. A number of studies have demonstrated the potential health benefits of bioactive compounds, i.e., flavonoids and vitamins, which may be effective as supplementary treatments for diabetes and its complications. In this review, we highlight the most recent reports about the mechanisms of action of bioactive compounds (flavonoids and vitamins) possessing potential neuroprotective properties in diabetic conditions. Additional clinical studies are required to determine the appropriate dose and duration of bioactive compound supplementation for neuroprotection in diabetic patients. PMID:27483315

[Pentosidine: a new biomarker in diabetes mellitus complications].

PubMed

Morales, Sonia; García-Salcedo, José A; Muñoz-Torres, Manuel

2011-03-19

Diabetes mellitus causes an increase of morbidity and mortality. Advanced glycosilation end products (AGE) are formed by non-enzymatic glycation between proteins and reducing sugars as glucose. Oxidative reactions (glycoxidations) are essential for the formation of some AGE, for example pentosidine. Increased concentrations of pentosidine can be found in pathological conditions associated with hyperglycaemia and also related to increased oxidative stress. In individuals with diabetes mellitus, pentosidine formation and accumulation is developed at an accelerated rate in cells without insulin control for glucose uptake. Pentosidine has a pivotal role in diabetic complications, probably as a consequence of the diverse properties of this compound, which alters the structure and function of molecules in biological systems. The following review discusses the alterations in the concentration of pentosidine in the body, particularly in relation to changes occurring in diabetes and its complications such as vascular and bone disease, nephropathy, neuropathy and retinopathy. Novel therapeutic approaches which can prevent or ameliorate the toxic effects of AGE in the initiation and progression of diabetic complications are reviewed. Copyright © 2009 Elsevier España, S.L.

C-peptide and Central Nervous System Complications in Diabetes

PubMed Central

Li, Zhen-guo

2004-01-01

Substantial evidence collected from clinical data and experimental studies has indicated that CNS is not spared from diabetes complications. Impairments in CNS function are well documented in both type 1 and type 2 diabetic patients as well as in various animal models of diabetes, in terms of alterations in cognition, neuropsychology, neurobehavior, electrophysiology, structure, neurochemistry and apoptotic activities. These data suggest that primary diabetic encephalopathy exists as a definable diabetic complication. The mechanisms underlying this CNS complication are not clear. Experimental studies have suggested that neuronal apoptosis may play an important role in neuronal loss and impaired cognitive function. In diabetes multiple factors are responsible for neuronal apoptosis, such as a perturbed IGF system, hyperglycemia and the aging process itself. Recent data suggest that insulin/C-peptide deficiency may exert an eminent role. Administration of C-peptide partially corrects the perturbed IGF system in the brain and prevents neuronal apoptosis in hippocampus of type 1 diabetes. In neuroblastoma SH-SY5Y cells C-peptide provides a dose-dependent stimulation on cell proliferation and an anti-apoptotic effect as well. These studies provide a basis for administration of C-peptide as a potentially effective therapy for type 1 diabetes. PMID:15198373

While in non-diabetic people the risk for cardiovascular disease is higher in men, diabetes completely reverts this sex-gender difference conferring to women a greater burden of cardiovascular complications. Additionally, all risk factors associated with cardiovascular disease appear to be more active in diabetic females than in their male counterparts. The reasons of this different impact of diabetes between genders are not completely clear. The aim of this review is trying to clarify these issues in a sex and gender perspective. Both genetic and hormonal factors are at the basis of sex-gender differences in diabetes, even do not explain the totality of data. Possibly women arrive later and in worse conditions to the diagnosis of diabetes, receive both diagnostic and therapeutic supports in a lesser measure and, finally, reach therapeutic goals as recommended by guidelines in a lesser extent. Further aspects of sex-gender differences in diabetic complications are represented by a more frequent prevalence of drug side effects in women, as well as by increased resistance to the action of drugs used in prevention or in the therapy of cardiovascular diseases. As to microvascular complications, the issue of sex-gender differences is even more complex, with some important differences emerging in experimental models 'in vitro', as well as in human pathology 'in vivo'. The main problem, however, also in this case, is that it is difficult to differentiate how common pathogenetic mechanisms acting in diabetes may differently impact between genders. In conclusion what is evident is that diabetes represents a 'risk magnifier' for the damage of both micro and macrovessels differently in men and in women. This issue deserves, therefore, a more careful approach from people involved in both clinical aspects and research regarding diabetes and its complications, in a sex-gender oriented perspective.

Although thermal imaging can be a valuable technology in the prevention and management of diabetic foot disease, it is not yet widely used in clinical practice. Technological advancement in infrared imaging increases its application range. The aim was to explore the first steps in the applicability of high-resolution infrared thermal imaging for noninvasive automated detection of signs of diabetic foot disease. The plantar foot surfaces of 15 diabetes patients were imaged with an infrared camera (resolution, 1.2 mm/pixel): 5 patients had no visible signs of foot complications, 5 patients had local complications (e.g., abundant callus or neuropathic ulcer), and 5 patients had diffuse complications (e.g., Charcot foot, infected ulcer, or critical ischemia). Foot temperature was calculated as mean temperature across pixels for the whole foot and for specified regions of interest (ROIs). No differences in mean temperature >1.5 °C between the ipsilateral and the contralateral foot were found in patients without complications. In patients with local complications, mean temperatures of the ipsilateral and the contralateral foot were similar, but temperature at the ROI was >2 °C higher compared with the corresponding region in the contralateral foot and to the mean of the whole ipsilateral foot. In patients with diffuse complications, mean temperature differences of >3 °C between ipsilateral and contralateral foot were found. With an algorithm based on parameters that can be captured and analyzed with a high-resolution infrared camera and a computer, it is possible to detect signs of diabetic foot disease and to discriminate between no, local, or diffuse diabetic foot complications. As such, an intelligent telemedicine monitoring system for noninvasive automated detection of signs of diabetic foot disease is one step closer. Future studies are essential to confirm and extend these promising early findings. © 2013 Diabetes Technology Society.

With the evolution of diabetes technology, those living with Type 1 diabetes are given a wider arsenal of tools with which to achieve glycaemic control and improve patient-reported outcomes. Furthermore, the use of these technologies may help reduce the risk of acute complications, such as severe hypoglycaemia and diabetic ketoacidosis, as well as long-term macro- and microvascular complications. In addition, diabetes technology can have a beneficial impact on psychosocial health by reducing the burden of diabetes. Unfortunately, diabetes goals are often unmet and people with Type 1 diabetes too frequently experience acute and long-term complications of this condition, in addition to often having less than ideal psychosocial outcomes. Increasing realization of the importance of patient-reported outcomes is leading to diabetes care delivery becoming more patient-centred. Diabetes technology in the form of medical devices, digital health and big data analytics have the potential to improve clinical care and psychosocial support, resulting in lower rates of acute and chronic complications, decreased burden of diabetes care, and improved quality of life. © 2018 Diabetes UK.

Nonalcoholic fatty liver disease and chronic vascular complications of diabetes mellitus.

PubMed

Targher, Giovanni; Lonardo, Amedeo; Byrne, Christopher D

2018-02-01

Nonalcoholic fatty liver disease (NAFLD) and diabetes mellitus are common diseases that often coexist and might act synergistically to increase the risk of hepatic and extra-hepatic clinical outcomes. NAFLD affects up to 70-80% of patients with type 2 diabetes mellitus and up to 30-40% of adults with type 1 diabetes mellitus. The coexistence of NAFLD and diabetes mellitus increases the risk of developing not only the more severe forms of NAFLD but also chronic vascular complications of diabetes mellitus. Indeed, substantial evidence links NAFLD with an increased risk of developing cardiovascular disease and other cardiac and arrhythmic complications in patients with type 1 diabetes mellitus or type 2 diabetes mellitus. NAFLD is also associated with an increased risk of developing microvascular diabetic complications, especially chronic kidney disease. This Review focuses on the strong association between NAFLD and the risk of chronic vascular complications in patients with type 1 diabetes mellitus or type 2 diabetes mellitus, thereby promoting an increased awareness of the extra-hepatic implications of this increasingly prevalent and burdensome liver disease. We also discuss the putative underlying mechanisms by which NAFLD contributes to vascular diseases, as well as the emerging role of changes in the gut microbiota (dysbiosis) in the pathogenesis of NAFLD and associated vascular diseases.

Diabetes is a disease, which has assumed vital public health importance because of the complications associated with it. Various mechanisms including polyol pathway along with a complex integrating paradigm have been implicated in glucose-mediated complications. Though polyol pathway was established as a major mechanism, precise pathogenesis of these complications is not yet completely elucidated. Thus research focus was shifted towards key enzyme, aldose reductase in the pathway. Even though various compounds with aldose reductase inhibitory activity were synthesised, a very few compounds are under clinical use. However, studies on these compounds were always under conflicting results and an attempt has been made to review various natural substances with aldose reductase inhibitory activity and their role in management of diabetic complications.

India is one of the epicentres of the global diabetes mellitus pandemic. Rapid socioeconomic development and demographic changes, along with increased susceptibility for Indian individuals, have led to the explosive increase in the prevalence of diabetes mellitus in India over the past four decades. Type 2 diabetes mellitus in Asian Indian people is characterized by a young age of onset and occurrence at low levels of BMI. Available data also suggest that the susceptibility of Asian Indian people to the complications of diabetes mellitus differs from that of white populations. Management of this disease in India faces multiple challenges, such as low levels of awareness, paucity of trained medical and paramedical staff and unaffordability of medications and services. Novel interventions using readily available resources and technology promise to revolutionise the care of patients with diabetes mellitus in India. As many of these challenges are common to most developing countries of the world, the lessons learnt from India's experience with diabetes mellitus are likely to be of immense global relevance. In this Review, we discuss the epidemiology of diabetes mellitus and its complications in India and outline the advances made in the country to ensure adequate care. We make specific references to novel, cost-effective interventions, which might be of relevance to other low-income and middle-income countries of the world.

Diabetes mellitus, part 1: physiology and complications.

PubMed

Nair, Muralitharan

In part 1 of this 2-part article the author discusses the physiology and complications of diabetes mellitus (DM), a chronic and progressive disorder which affects all ages of the population. The number of people diagnosed with diabetes is approximately 1.8 million and an estimated further 1 million are undiagnosed (Department of Health, 2005). In the UK, 1-2% of the population have diabetes and among school children this is approximately 2 in 1000 (Watkins, 1996). There are two main types of diabetes--type 1 and type 2 (Porth, 2005). The aetiology of DM is unknown; however, genetic and environmental factors have been linked to its development. Type 1 results from the loss of insulin production in the beta cells of the pancreas, and type 2 from a lack of serum insulin or poor uptake of glucose into the cells. Diabetes causes disease in many organs in the body, which may be life-threatening if untreated. Complications such as heart disease, vascular disease, renal failure and blindness (Roberts, 2005) have all been reported. The increased prevalence may be caused by factors such as environmental aspects, diet, an ageing population and low levels of physical exercise.

In Arabic folk medicine, the seeds of Phoenix dactylifera L. (Arecaceae) have been used to manage diabetes for many years. Few studies have reported the antidiabetic effect of P. dactylifera seeds; however, their effect on diabetic complications is still unexplored. The present study investigates the protective effect of P. dactylifera seeds against diabetic complications in rats. The aqueous suspension of P. dactylifera seeds (aqPDS) (1 g/kg/d) was orally administered to streptozotocin-induced diabetic rats for 4 weeks. The serum biochemical parameters were assessed spectrophotometrically. Furthermore, oxidative stress was examined in both liver and kidney tissues by assessment of thiobarbituric acid reactive substances (TBARS), nitric oxide (NO), reduced glutathione, superoxide dismutase (SOD), glutathione S-transferase, and catalase. Oral administration of aqPDS significantly ameliorated the elevated levels of glucose (248 ± 42 versus 508 ± 60 mg/dl), urea (32 ± 3.3 versus 48.3 ± 5.6 mg/dl), creatinine (2.2 ± 0.35 versus 3.8 ± 0.37 mg/dl), ALT (29.6 ± 3.9 versus 46.4 ± 5.9 IU/l), and AST (73.3 ± 13 versus 127.8 ± 18.7 IU/l) compared with the untreated diabetic rats. In addition to significant augmentation in the activities of antioxidant enzymes, there was reduction in TBARS and NO levels and improvement of histopathological architecture of the liver and kidney of diabetic rats. The aqPDS showed potential protective effects against early diabetic complications of both liver and kidney. This effect may be explained by the antioxidant and free radical scavenging capabilities of P. dactylifera seeds.

The role of the family doctor in fundamental in the prevention of diabetic complications, because these complications will be minor if there is good glycemic control during life. Determine the frequency of late complications of diabetes mellitus (DM) among IMSS-insured population in Ciudad Obregón, Sonora, México. A retrospective analysis included 252 diabetic patients selected by a systematized and stratified randomized sampling including all patient files available in the Family Medicine Unit 1 in Ciudad Obregón, Sonora. The information was taken from the clinical charts got by family physicians and specialists. We used descriptive statistics and correlation of Pearson looking for the association between glicemia's level and enough time to produce complications. Arterial hypertension was found in 168 cases (67%), hypertriglyceridemia in 148 (59.4%), neuropathy in 106 (42.6%), hypercholesterolemia in 89 (35.7%), retinopathy in 69 (27.5%), nephropathy in 51 (20.5%), diabetic foot in 27 (10.8%), ischemic cardiopathy in 25 (10%), cerebral thrombosis in 11 (4.4%). The period between DM diagnosis and the appearance of complications was 3.2 to 13.1 years. The correlations were high and significant in every complication. The frequency of DM complications in this study was very high, with an increasing tendency of developing complications throughout the time.

Background Although thermal imaging can be a valuable technology in the prevention and management of diabetic foot disease, it is not yet widely used in clinical practice. Technological advancement in infrared imaging increases its application range. The aim was to explore the first steps in the applicability of high-resolution infrared thermal imaging for noninvasive automated detection of signs of diabetic foot disease. Methods The plantar foot surfaces of 15 diabetes patients were imaged with an infrared camera (resolution, 1.2 mm/pixel): 5 patients had no visible signs of foot complications, 5 patients had local complications (e.g., abundant callus or neuropathic ulcer), and 5 patients had diffuse complications (e.g., Charcot foot, infected ulcer, or critical ischemia). Foot temperature was calculated as mean temperature across pixels for the whole foot and for specified regions of interest (ROIs). Results No differences in mean temperature >1.5 °C between the ipsilateral and the contralateral foot were found in patients without complications. In patients with local complications, mean temperatures of the ipsilateral and the contralateral foot were similar, but temperature at the ROI was >2 °C higher compared with the corresponding region in the contralateral foot and to the mean of the whole ipsilateral foot. In patients with diffuse complications, mean temperature differences of >3 °C between ipsilateral and contralateral foot were found. Conclusions With an algorithm based on parameters that can be captured and analyzed with a high-resolution infrared camera and a computer, it is possible to detect signs of diabetic foot disease and to discriminate between no, local, or diffuse diabetic foot complications. As such, an intelligent telemedicine monitoring system for noninvasive automated detection of signs of diabetic foot disease is one step closer. Future studies are essential to confirm and extend these promising early findings. PMID:24124937

Objective To examine the association between processes measures of diabetes care and time to progression for four complications of diabetes - Coronary Artery Disease (CAD), Stroke, Heart Failure (HF), and Renal Disease (RD). Study Design This retrospective study followed outcomes from 2003 through 2009 in a cohort of 1,797 employees with diabetes who worked for a large US manufacturer and were enrolled in the same health insurance plan. Methods Quality of care was measured by consensus standards for testing A1C, lipids and microalbuminuria. Employees with diabetes who received all three measures of care in the baseline year (2003) were compared to those who received less complete testing. Cox proportional hazard regression models were used to assess potential associations between diabetes care and time to complication, controlling for potential confounders. Results Observed differences between the two groups in time-to-event were significant for two of the four complications: HF (HR 0.39, 95% CI [0.19 – 0.81], p = 0.0117), and RD (HR 0.48, 95% CI [0.24 – 0.95], p = 0.0339) and any of the four complications (HR 0.66, 95% CI [0.48 – 0.91], p = 0.0101). Differences in time to complication for CAD (HR 0.70, 95% CI [0.49 – 1.02], p = 0.0635) and Stroke (HR 0.63, 95% CI [0.38 – 1.07], p = 0.0891) showed the same trend but were not significant. Conclusions In this cohort, employees with diabetes who received all three quality measures experienced reduced complication risk - adjusting for other factors. These results provide support for the importance of care quality and its assessment. PMID:24512164

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.

To estimate the prevalence of diabetic foot complications among patients at a specialist diabetes clinic in Jamaica and identify factors associated with foot complications. A stratified random sample of 188 patients were interviewed and examined between 2009 and 2010. Trained nurses obtained demographic and clinical data, measured anthropometrics and performedfoot examinations including inspection for amputations, ulcers or infection and assessment of pain, vibration and pressure perception. Participants included 143 women and 45 men (mean age 56years; mean diabetes duration 16 years). The prevalence of amputations was 8.5% (95% CI 4.5, 12.5%) and was higher among men (22.2%) compared to women (4.2%, p < 0.05). Prevalence of current ulcers and current foot infections was 4.3% and 3.7%, respectively. Overall, 12% ofpatients had at least one of these foot complications. Foot complications were more prevalent among men, patients with high blood pressure (BP > or = 130/80 mmHg) or peripheral neuropathy In multivariable logistic regression models, factors associated with foot complications were: neuropathy (OR 9.3 [95% CI 2.8, 30.3]), high BP (OR 7.9 [1.3, 49.7]) and diabetes duration (OR 1.32 [1.02, 1.72]). Approximately one of every eight patients in this specialist clinic had a major foot complication. Associated factors were neuropathy, high blood pressure and longer duration of diabetes.

Diabetes, whether or not it is insulin deficient, is frequently associated with vascular complications during pregnancies. It is accepted nowadays that the uterine artery velocity waveform is predictive concerning pregnancy-induced hypertension (PIH) and its complications. It thus seemed interesting to analyse the predictivity of vascular complications of diabetes by using uterine artery velocity waveforms. We have thus explored 37 diabetic patients [group 1: insulin-deficient diabetes (IDD), n = 10; group 2: gestational IDD, n = 6; and gestational non-IDD, n = 21). We have found vascular complications for 10 patients, divided between all 2 groups: 2 pre-eclampsia, 2 fetal suffering before any labour, 2 cases of intra-uterine growth retardation (including a trisomy 18) and 5 PIH. The uterine artery velocimetry measurement has been found to be pathological 5 times, and always in patients who later developed vascular complications. Among this selected population and excluding the trisomy 18, the sensitivity is of 44.5%, the specificity of 100%, the positive predictive value of 100%, and the negative predictive value of 84.3%. If these results are confirmed, this examination could be an excellent marker of the vascular risk and thus would have its place during systematic survey of pregnancies complicated by diabetes.

Although microvascular complications of diabetes (retinopathy, neuropathy, and nephropathy) affect different organs, they are strongly correlated to each other. Based on recent data, their onset and progression could be directly monitored, focusing our attention only on the eye. When confirmed and standardized, this approach could allow one to simplify the way in which we follow the progression of different diabetic complications, and thus establish new strategies aimed at preventing, treating and, hopefully, inducing the remission of microvascular complications of diabetes. © 2017 S.

Taiwan's National Health Insurance medical claims. 4007 patients newly diagnosed with type 1 diabetes were identified during 1999-2012. Acute complications included diabetic ketoacidosis (DKA) and hypoglycaemia. Chronic complications were cardiovascular diseases (CVD), retinopathy, neuropathy and nephropathy. The incidence density of retinopathy was greatest (97.74 per 1000 person-years), followed by those of nephropathy (31.36), neuropathy (23.93) and CVD (4.39). Among acute complications, the incidence density of DKA was greatest (121.11 per 1000 person-years). The cumulative incidences of acute complications after 12 years following diagnosis were estimated to be 52.1%, 36.1% and 4.1% for DKA, outpatient hypoglycaemia and hospitalised hypoglycaemia, respectively. For chronic complications, the cumulative incidence of retinopathy after 12 years following diagnosis was greatest (65.2%), followed by those of nephropathy (30.2%), neuropathy (23.7%) and CVD (4.1%). Females with late-onset diabetes were greatly affected by advanced retinopathy (ie, sight-threatening diabetic retinopathy) and hospitalised hypoglycaemia, whereas those with early-onset diabetes were more vulnerable to DKA. Chronic complications were more commonly seen in late-onset diabetes, whereas early-onset diabetes were most affected by acute complications. Ethnic Chinese patients with type 1 diabetes were greatly affected by DKA and retinopathy. The incidence of diabetes-related complications differed by age at diagnosis and sex. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Diabetes mellitus (DM) appears to be a global epidemic and an increasingly major non-communicable disease threatening both affluent and non-affluent society. The study aimed to determine the knowledge of diabetic complications among diabetes mellitus clients visiting the Diabetic Clinical at Sampa Government Hospital, Ghana. This questionnaire-based descriptive study recruited a total 630 patients visiting the Diabetes Clinic at the Sampa Government Hospital. Structured questionnaire was used to obtain information such as socio-demographic and knowledge on complications of diabetes. Out of a total of 630 participants, 325 (51.5 %) knew diabetic foot as the most common complication followed by hypertension 223(35.4 %), neuropathy 184 (29.2 %), hypoactive sexual arousal 160(25.4 %), arousal disorder 135(21.5 %), eye diseases 112(17.7 %), heart disease 58(9.2 %), and renal disease 34(5.4 %). Comprehensive assessment of level of knowledge on the complications showed that majority 378(60.0 %) of T2D patients did not have knowledge on diabetes complications, 169(26.9 %) had inadequate knowledge on diabetics complication while 82(13.1 %) had adequate knowledge. The risk factors associated with the level of knowledge of diabetic complications were female gender adjusted odd ratio (AOR) =2.31 (1.56-3.41) married participants AOR = 3.37 (1.44-7.93), widowed AOR = 2.98 (1.10-8.08), basic level of education AOR =0.18 (0.082-0.50), Junior High School (JHS) and above of education level AOR = 0.035(0.017-0.75), 5-9 years of T2D duration AOR = 0.31(0.018-0.57), ≥10 years T2D duration AOR = 0.042 (0.02-0.10) and urban dwellers AOR = 0.36 (0.22-0.68) respectively.

People with diabetes are at risk of developing complications that contribute to substantial morbidity and mortality. In 2011, the American Association of Diabetes Educators convened an invitational Reducing Risks Symposium, during which an interdisciplinary panel of 11 thought leaders examined current knowledge about the reduction and prevention of diabetes-related risks and translated evidence into diabetes care and self-management education. Symposium participants reviewed findings from the literature and engaged in a moderated roundtable discussion. This report summarizes the discussion and presents recommendations to incorporate into practice to improve outcomes. The objective of the symposium was to develop practical advice for diabetes educators and other members of the diabetes care team regarding the reduction of diabetes-related risks. Optimal diabetes management requires patients to actively participate in their care, which occurs most effectively with a multidisciplinary team. Diabetes education is an integral part of this team approach because it not only helps the patient understand diabetes, its progression, and possible complications, but also provides guidance and encouragement to the patient to engage in proactive risk-reduction decisions for optimal health. A variety of tools are available to help the diabetes educator develop an individualized, patient-centered plan for risk reduction. More research is needed regarding intervention efficacy, best practices to improve adherence, and quantification of benefits from ongoing diabetes support in risk reduction. Diabetes educators are urged to stay abreast of evolving models of care and to build relationships with health care providers both within and beyond the diabetes care team.

Statin use is associated with increased incidence of diabetes and possibly with increased body weight and reduced exercise capacity. Data on the long-term effects of these associations in healthy adults, however, are very limited. In addition, the relationship between these effects and diabetic complications has not been adequately studied. To examine the association between statin use and new-onset diabetes, diabetic complications, and overweight/obesity in a cohort of healthy adults. This was a retrospective cohort study. Subjects were Tricare beneficiaries who were evaluated between October 1, 2003 and March 1, 2012. Patients were divided into statin users and nonusers. We excluded patients who, at baseline, had a preexisting disease indicative of cardiovascular diseases, any positive element of the Charlson comorbidity index (including diabetes mellitus), or life-limiting chronic diseases. Using 42 baseline characteristics, we generated a propensity score to match statin users and nonusers. Outcomes assessed included new-onset diabetes, diabetic complications, and overweight/obesity. A total of 25,970 patients (3982 statin users and 21,988 nonusers) were identified as healthy adults at baseline. Of these, 3351 statins users and 3351 nonusers were propensity score-matched. Statin users had higher odds of new-onset diabetes (odds ratio [OR] 1.87; 95 % confidence interval [95 % CI] 1.67-2.01), diabetes with complications (OR 2.50; 95 % CI 1.88-3.32), and overweight/obesity (OR 1.14; 95 % CI 1.04-1.25). Secondary and sensitivity analyses demonstrated similar findings. Diabetes, diabetic complications, and overweight/obesity were more commonly diagnosed among statin-users than similar nonusers in a healthy cohort of adults. This study demonstrates that short-term clinical trials might not fully describe the risk/benefit of long-term statin use for primary prevention.

The Protective Effect of Antioxidants Consumption on Diabetes and Vascular Complications

Obesity and diabetes is generally accompanied by a chronic state of oxidative stress, disequilibrium in the redox balance, implicated in the development and progression of complications such as micro- and macro-angiopathies. Disorders in the inner layer of blood vessels, the endothelium, play an early and critical role in the development of these complications. Blunted endothelium-dependent relaxation and/or contractions are quietly associated to oxidative stress. Thus, preserving endothelial function and oxidative stress seems to be an optimization strategy in the prevention of vascular complications associated with diabetes. Diet is a major lifestyle factor that can greatly influence the incidence and the progression of type 2 diabetes and cardiovascular complications. The notion that foods not only provide basic nutrition but can also prevent diseases and ensure good health and longevity is now attained greater prominence. Some dietary and lifestyle modifications associated to antioxidative supply could be an effective prophylactic means to fight against oxidative stress in diabesity and complications. A significant benefit of phytochemicals (polyphenols in wine, grape, teas), vitamins (ascorbate, tocopherol), minerals (selenium, magnesium), and fruits and vegetables in foods is thought to be capable of scavenging free radicals, lowering the incidence of chronic diseases. In this review, we discuss the role of oxidative stress in diabetes and complications, highlight the endothelial dysfunction, and examine the impact of antioxidant foods, plants, fruits, and vegetables, currently used medication with antioxidant properties, in relation to the development and progression of diabetes and cardiovascular complications.

To assess the impact of diabetes and diabetes-related complications on two measures of productivity for people in the labour force and out of it, namely "being afraid health limits ability to work before retirement" and "volunteering". Logistic regressions were run to test the impact of diabetes and its complications on the probability of being afraid health limits work and being a formal volunteer. The longitudinal sample for the former outcome includes 53,631 observations, clustered in 34,393 individuals, aged 50-65 years old whereas the latter consists of 45,384 observations, grouped in 29,104 individuals aged 65 and above across twelve European countries taken from the Survey of Health, Ageing and Retirement in Europe, from 2006 to 2013. Diabetes increased the probability of being afraid health limited work by nearly 11% points, adjusted by clinical complications, and reduced the likelihood of being a formal volunteer by 2.7% points, additionally adjusted by mobility problems. We also found that both the probability of being afraid health limits work and the probability of being a formal volunteer increased during and after the crisis. Moreover, having diabetes had a larger effect on being afraid health limits work during the year 2010, possibly related to the financial crisis. Our findings show that diabetes significantly affects the perception of people regarding the effects of their condition on work, increasing the fear that health limits their ability to work, especially during the crisis year 2010, as well as the participation in volunteering work among retired people.

Vascular complications are the leading cause of morbidity and mortality among patients with type 1 and type 2 diabetes mellitus. These vascular abnormalities result of a chronic hyperglycemic state, which leads to an increase in oxidative stress and inflammatory responses. This review addresses the relationships among endothelial dysfunction, hypercoagulability and inflammation and their biomarkers in the development of vascular complications in type 1 and type 2 diabetes. Inflammation, endothelial dysfunction, and hypercoagulability are correlated to each other, playing an important role in the development of vascular complications in diabetic patients. Moreover, it has been observed that several endothelial, inflammatory and pro-coagulant biomarkers, such as VWF, IL-6, TNF-α, D-dimer and PAI-1, are increased in diabetic patients who have microvascular and macrovascular complications, including nephropathy or cardiovascular disease. It is promising the clinical and laboratory use of endothelial, inflammatory and pro-coagulant biomarkers for predicting the risk of cardiovascular and renal complications in diabetic patients and for monitoring these patients.

Endothelin (ET) peptides perform several physiological, vascular, and nonvascular functions and are widely distributed in a number of tissues. They are altered in several disease processes including diabetes. Alteration of ETs have been demonstrated in organs of chronic diabetic complications in both experimental and clinical studies. The majority of the effects of ET alteration in diabetes are due to altered vascular function. Furthermore, ET antagonists have been shown to prevent structural and functional changes induced by diabetes in animal models. This review discusses the contribution of ETs in the pathogenesis and the potential role of ET antagonism in the treatment of chronic diabetic complications. PMID:12546275

2016-01-01

Diabetes causes many complications, including retinopathy and peripheral neuropathy, which are well understood as contributing to gait instability and falls. A less understood complication of diabetes is the effect on the vestibular system. The vestibular system contributes significantly to balance in static and dynamic conditions by providing spatially orienting information. It is noteworthy that diabetes has been reported to affect vestibular function in both animal and clinical studies. Pathophysiological changes in peripheral and central vestibular structures due to diabetes have been noted. Vestibular dysfunction is associated with impaired balance and a higher risk of falls. As the prevalence of diabetes increases, so does the potential for falls due to diabetic complications. The purpose of this perspective article is to present evidence on the pathophysiology of diabetes-related complications and their influence on balance and falls, with specific attention to emerging evidence of vestibular dysfunction due to diabetes. Understanding this relationship may be useful for screening (by physical therapists) for possible vestibular dysfunction in people with diabetes and for further developing and testing the efficacy of interventions to reduce falls in this population.

Cardiovascular complications are the major causes of mortality among diabetic population. Poly(ADP-ribose) polymerase-1 enzyme (PARP-1) is activated by oxidative stress leading to cellular damage. We investigated the implication of PARP-1 in diabetic cardiac complications. Type 2 diabetes was induced in rats by high fructose-high fat diet and low streptozotocin dose. PARP inhibitor 4-aminobenzamide (4-AB) was administered daily for ten weeks after diabetes induction. At the end of study, surface ECG, blood pressure and vascular reactivity were studied. PARP-1 activity, reduced glutathione (GSH) and nitrite contents were assessed in heart muscle. Fasting glucose, fructosamine, insulin, and tumor necrosis factor alpha (TNF-α) levels were measured in serum. Finally, histological examination and collagen deposition detection in rat ventricular and aortic sections were carried out. Hearts isolated from diabetic animals showed increased PARP-1 enzyme activity compared to control animals while significantly reduced by 4-AB administration. PARP-1 inhibition by 4-AB alleviated cardiac ischemia in diabetic animals as indicated by ECG changes. PARP-1 inhibition also reduced cardiac inflammation in diabetic animals as evidenced by histopathological changes. In addition, 4-AB administration improved the elevated blood pressure and the associated exaggerated vascular contractility, endothelial destruction and vascular inflammation seen in diabetic animals. Moreover, PARP-1 inhibition decreased serum levels of TNF-α and cardiac nitrite but increased cardiac GSH contents in diabetic animals. However, PARP-1 inhibition did not significantly affect the developed hyperglycemia. Our findings prove that PARP-1 enzyme plays an important role in diabetic cardiac complications through combining inflammation, oxidative stress, and fibrosis mechanisms. Copyright © 2016.

Diabetes mellitus has been linked with a variety of perioperative adverse events across surgical disciplines. There is a paucity of studies systematically examining risk factors, including diabetes, and complications of aesthetic surgical procedures. The purpose of this study was to compare incidence and type of complications between diabetic and non-diabetic patients undergoing various aesthetic surgical procedures, to identify specific procedures where diabetes significantly increases risk of complications, and to study diabetes as an independent risk factor for major complications following aesthetic surgery. A prospective cohort of 129,007 patients who enrolled into the CosmetAssure insurance program and underwent cosmetic surgical procedures between May 2008 and May 2013 were reviewed. Diabetes was evaluated as risk factor for major complications, requiring hospital admission, emergency room visit, or a reoperation within 30 days after surgery. Multivariate regression analysis was performed controlling for the effects of age, smoking, obesity, gender, type of procedures, and surgical facility. Overall, 2506 patients (1.9%) had a major complication. Diabetics had significantly more complications compared to non-diabetics (3.1% vs 1.9%, P < 0.01). In univariate analysis, infectious (1.1% vs 0.5%, P < 0.01) and pulmonary (0.3% vs 0.1%, P < 0.01) complications were significantly higher among diabetics. Notably, diabetics had higher risks of complication in body cases (4.3% vs 2.6%, P < 0.01) and specifically abdominoplasty (6.1% vs 3.0%, P < 0.01). In multivariate analysis, diabetes was found to be an independent risk factor of any complication (relative risk 1.31, P = 0.03) and infection (relative risk 1.70, P < 0.01). Diabetes is an independent risk factor of major complications, particularly infection, after aesthetic surgical procedures. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Laughter has been used for centuries to alleviate pain in morbid conditions. It was not until 1976 that scientists thought about laughter as a form of therapy that can modulate hormonal and immunological parameters that affect the outcome of many serious diseases. Moreover, laughter therapy was shown to be beneficial in type 2 diabetes mellitus (T2DM) by delaying the onset of many diabetic complications. Laughter is also described to influence the cardiovascular and endothelial functions and thus may protect against diabetic cardiovascular complications. In this review, we outline the different biochemical, physiological and immunological mechanisms by which laughter may influence the overall state of wellbeing and enhance disease prognosis. We also focus on the biological link between laughter therapy and diabetic cardiovascular complications as well as the underlying mechanisms involved in T2DM. Reviewing all the essential databases for "laughter" and "type 2 diabetes mellitus". Although laughter therapy is still poorly investigated, recent studies show that laughter may retard the onset of diabetic complications, enhance cardiovascular functions and rectify homeostatic abnormalities associated with T2DM. Laughter therapy is effective in delaying diabetic complications and should be used as an adjuvant therapy. Copyright © 2017 Elsevier B.V. All rights reserved.

The telomere-telomerase system plays an important role in the pathogenesis and disease progression of diabetes mellitus as well as in its vascular complications. Recent studies suggest that telomere shortening and abnormal telomerase activity occur in patients with diabetes mellitus, and targeting the telomere-telomerase system has become a prospective treatment for diabetes mellitus and its vascular complications. This review highlights the significance of the telomere-telomerase system and supports its role as a possible therapeutic target for patients with diabetes mellitus and its vascular complications Areas covered: This review covers the advances in understanding the telomere-telomerase system over the last 30 years and its significance in diabetes mellitus. In addition, it provides knowledge regarding the significance of the telomere-telomerase system in diabetes mellitus and its vascular complications as well as its role and mechanisms in oxidative stress, cell therapy and antioxidant activity Expert opinion: The telomere-telomerase system may be a potential therapeutic target that can protect against DNA damage and apoptosis in patients with diabetes mellitus and its vascular complications. DNA damage and apoptosis are associated with oxidative stress and are involved in the dysfunction of pancreatic β cells, insulin resistance, and its vascular complications. Abnormalities in the telomere-telomerase system may be associated with diabetes mellitus and its vascular complications. Therapies targeting telomere-telomerase system, telomerase reverse transcriptase transfection and alterative telomere lengthening must be identified before gene therapy can commence.

Abstract Conventional stroke risk prediction tools used in atrial fibrillation (AF) incorporate the presence of diabetes mellitus (DM) as a risk factor. However, it is unknown whether this risk is homogenous or dependent on the presence of diabetic microvascular complications, such as diabetic retinopathy, nephropathy, and neuropathy. The present study examined the risk of ischemic stroke in diabetic patients with and without microvascular complications. The present study used the National Health Insurance Research Database in Taiwan with detailed healthcare data on all-comers to the Taiwanese medical system from January 1, 1996 to December 31, 2011. AF and DM were identified when listed as discharge diagnoses or confirmed more than twice in the outpatient department. Patients on antithrombotic agents were excluded. The clinical endpoint was ischemic stroke. Among the 50,180 AF patients with DM, the majority had no microvascular complications (72.7%), while 2.6% had diabetic retinopathy, 8.4% had diabetic nephropathy, and 16.1% had diabetic neuropathy. Ischemic stroke occurred in 6003 patients, with a 4.74% annual risk of ischemic stroke. When compared with DM patients without microvascular complications, those with diabetic retinopathy, nephropathy, or neuropathy had higher incidences of ischemic stroke (4.65 vs 5.07, 4.77, or 5.20 per 100 person-years, respectively). However, after adjusting for confounding factors, the differences were no longer significant. In a large nationwide AF cohort with DM, risk of ischemic stroke was similar between patients with and without microvascular complications, suggesting that risk stratification of these patients does not require inclusion of diabetic retinopathy, nephropathy, and neuropathy.

This pictorial review aims to illustrate the various manifestations of the diabetic foot on magnetic resonance (MR) imaging. The utility of MR imaging and its imaging features in the diagnosis of pedal osteomyelitis are illustrated. There is often difficulty encountered in distinguishing osteomyelitis from neuroarthropathy, both clinically and on imaging. By providing an accurate diagnosis based on imaging, the radiologist plays a significant role in the management of patients with complications of diabetic foot. PMID:25640096

Background Nephrogenic diabetes insipidus (NDI) is a rare disease whose complications include polyuria, renal dysfunction, growth disorder and mental retardation. The details of NDI’s clinical course have been unclear. To address this uncertainty, we performed a large investigation of the clinical course of NDI in Japan. Methods Between December 2009 and March 2011, we provided a primary questionnaire to 26,282 members of the Japan Endocrine Society, the Japanese Urological Association, the Japanese Society for Pediatric Endocrinology, the Japanese Society for Pediatric Nephrology, the Japanese Society of Nephrology, the Japanese Society of Neurology and the Japanese Society of Pediatric Urology. In addition, we provided a secondary questionnaire to 121 members who reported experience with cases of NDI. We asked about patient’s age at onset, diagnosis, complications, effect of treatment and patient’s genotype. Results We enrolled 173 patients with NDI in our study. Of these NDI patients, 143 were congenital and 30 were acquired. Of the 173, 73 patients (42%) experienced urologic complications. Among the 143 with congenital NDI, 20 patients (14%) had mental retardation. Patients with NDI mainly received thiazide diuretics, and some patients responded to treatment with desmopressin acetate (DDAVP). Gene analyses were performed in 87 patients (61%) with congenital NDI, revealing that 65 patients had an arginine vasopressin receptor type 2 (AVPR2) gene mutation and that 8 patients (9.2%) had an aquaporin 2 (AQP2) gene mutation. Patients with the AVPR2 mutation (D85N) generally showed a mild phenotype, and we found that DDAVP was generally an effective treatment for NDI among these patients. Conclusion We suggest that adequate diagnosis and treatment are the most important factors for improving prognoses. We further suggest that gene analysis should be performed for optimal treatment selection and the early detection of NDI among siblings. PMID:25324589

Many African Americans (AA) have both sickle cell trait (SCT) and diabetes mellitus. The objective of this study was to determine whether individuals with diabetes mellitus and SCT have higher rates of microvascular complications relative to those without SCT. This was a retrospective study comparing albuminuria, estimated GFR (eGFR), and microvascular complications in AA with diabetes on the basis of presence of SCT. The study included 821 outpatients who underwent hemoglobin A1c (HbA1c) testing, and presence of SCT was determined using the HbA1c assay. Medical record review and telephone interviews were performed for AA participants. Data were obtained on 376 AA patients (110 with SCT, 245 with neither SCT nor hemoglobin C trait, and 21 with hemoglobin C trait) and 445 European Americans. The mean eGFR and urinary protein excretion were similar between the three AA subgroups. Analysis revealed that 36.3% of AA nontrait and 22.7% of AA SCT participants had retinopathy, peripheral vascular disease, or end-stage kidney disease (P = 0.01). After adjustment for diabetes duration, age, insulin use, and gender, differences in the prevalence of microvascular complications were not observed. SCT does not increase the risk of microvascular complications in AA with diabetes mellitus.

The study was designed to investigate whether the hamilton rating scale for depression (24-items) (HAM-D 24 ) can be used to predict the diabetic microvascular complications in type 2 diabetes mellitus (T2DM) patients. 288 hospitalized patients with T2DM were enrolled. Their diabetic microvascular complications including diabetic nephropathy, diabetic retinopathy, diabetic peripheral neuropathy and diabetic foot as well as demographic, clinical data, blood samples and echocardiography were documented. All the enrolled patients received HAM-D 24 evaluation. The HAM-D 24 score and incidence of depression in T2DM patients with each diabetic microvascular complication were significantly higher than those in T2DM patients without each diabetic microvascular complication. After the adjustment of use of insulin and hypoglycemic drug, duration of T2DM, mean platelet volume, creatinine, albumin, fasting glucose, glycosylated hemoglobin type A1C, left ventricular ejection fraction, respectively, HAM-D 24 score was still significantly associated with diabetic microvascular complications (OR = 1.188-1.281, all P < 0.001). The AUC of HAM-D 24 score for the prediction of diabetic microvascular complication was 0.832 (0.761-0.902). 15 points of HAM-D 24 score was considered as the optimal cutoff with the sensitivity of 0.778 and specificity of 0.785. In summary, HAM-D 24 score may be used as a novel predictor of diabetic microvascular complications in T2DM patients. Copyright © 2017 Elsevier B.V. All rights reserved.

This paper examines how to develop a Model for Knowledge Management System (KMS) for diabetes complication diseases. People with diabetes have a higher risk of developing a series of serious health problems. Each patient has different condition that could lead to different disease and health problem. But, with the right information, patient could have early detection so the health risk could be minimized and avoided. Hence, the objective of this research is to propose a conceptual framework that integrates social network model, Knowledge Management activities, and content based reasoning (CBR) for designing such a diabetes health and complication disease KMS. The framework indicates that the critical knowledge management activities are in the process to find similar case and the index table for algorithm to fit the framework for the social media. With this framework, KMS developers can work with healthcare provider to easily identify the suitable IT associated with the CBR process when developing a diabetes KMS.

Diabetes mellitus is a vastly prevalent metabolic disorder with escalating global health concerns. Particularly when mismanaged, chronic micro- and macrovascular complications may highly impair physiological systems while immunodeficiency disposes us to infection. We investigate infections, localized complications, and neoplasms of the genitourinary system secondary to the chronic complications of diabetes mellitus in males and females. A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and the genitourinary system. Pathogen-friendly environments may implicate the sequelae of urinary tract and genital mycotic infections, potentially generating necrosis, abscess, and other inflammatory complications, which may present concomitantly with neurogenic and/or vasculogenic dysfunction to further exacerbate an existing genitourinary condition. Manifestations of the adrenal, renal, and genital organs and tissues are discussed as they relate to vascular, immunodeficient, and other hyperglycemic complications of the diabetic state. Among those, chronic kidney disease and cystopathy are the most prevailing and detrimental. Though studies have connected diabetes to either an increased risk of developing or poor prognosis of bladder, renal, prostate, endometrial, and cervical cancers, the explicit biological relationships are as of yet inconclusive. Despite the availability of precise treatments to ameliorate most presently reviewed conditions, particularly urinary tract and genital mycotic infection-related sequelae, reversing permanent vascular damage remains a great challenge. Leading a healthier lifestyle and managing diabetes mellitus with a patient-centric approach from the outset are the most putative methods for preventing critical long-term genitourinary manifestations of diabetes mellitus.

Some previous studies suggested that patients suffering from Wolfram syndrome or DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness) might be relatively preserved from diabetic retinopathy and nephropathy. However, these data were not conclusive because either observations were only anecdotic or did not match with control type 1 diabetic populations. A group of 26 French diabetic patients with DIDMOAD was compared with a population of 52 patients with common type 1 diabetes matched for age at diabetes diagnosis (8.62 +/- 1.84 vs. 8.27 +/- 1.30 years; P = NS) and diabetes duration (12.88 +/- 1.58 vs. 12.87 +/- 1.13 years; P = NS) to study the quality of glycemic control and the incidence of microvascular complications. Glycemic control was significantly better in the DIDMOAD group than in the type 1 diabetic group (A1C: 7.72 +/- 0.21 vs. 8.99 +/- 0.25%, respectively; P = 0.002), with significant lower daily insulin requirements (0.71 +/- 0.07 vs. 0.88 +/- 0.04 UI x kg(-1) x day(-1), respectively; P = 0.0325). The prevalence of microvascular complications in the DIDMOAD group was half that observed in the type 1 diabetic group, but the difference was not significant. Diabetes in DIDMOAD patients is more easily controlled despite the presence of other handicaps. This better glycemic control could explain the trend to decreased microvascular diabetes complications observed in previous studies.

We investigated whether erythrocyte aggregation (EA) is enhanced in type 2 diabetic patients who have developed microvascular or macrovascular complications. EA rates at high and low shear rates were analysed in 141 patients with type 2 diabetes who were further divided into 4 subgroups according to the status of diabetic complications and degree of metabolic control. Groups 1 (n = 43) and 2 (n = 23) consisted of well-controlled patients without and with clinically evident late complications, while groups 3 (n = 33) and 4 (n = 42) represented poorly controlled patients without and with these complications, respectively. 124 healthy subjects served as the control group. Mean EA rate was comparable between control subjects and group 1 both at high (2.05 +/- 0.03 vs. 2.14 +/- 0.07, respectively) and low (6.96 +/- 0.02 vs. 7.04 +/- 0.06, respectively) shear rates. Mean EA rate was also comparable between groups 2 and 4 at high (2.76 +/- 0.09 vs. 2.94 +/- 0.07, respectively) and low (8.18 +/- 0.13 vs. 8.41 +/- 0.1, respectively) shear rates. However, EA at both shear rates in groups 2 and 4 were significantly higher than control subjects, group 1 (p < 0.0001) and group 3 (high shear rate EA: 2.76 +/- 0.09 and low shear rate EA: 7.48 +/- 0.07 (p < 0.01). In group 3, EA rates were significantly higher than control subjects and group 1 (p < 0.05) at both shear rates. No significant correlation was found between EA at high and low shear rates and fibrinogen levels in diabetic subgroups and control subjects. The data suggest that patients with type 2 diabetes who had developed clinically evident late complications have enhanced EA regardless of the degree of metabolic control. Whether enhanced EA is a primary phenomenon contributing to the development of these complications or it occurs secondary to their development remains to be clarified.

The aim of the present study was to investigate hospitalization costs, diabetes complications, and their relationships using a large dataset in Beijing, China. Data for 2006-10 from the 38 top-ranked (Grade 3 A) hospitals in Beijing, obtained from electronic Hospitalization Summary Reports (HSRs), were analyzed for hospitalization costs and diabetic complications. Patient demographics, types of costs, and length of hospital stay (LOS) were also evaluated. During the period evaluated, 62 523 patients with diabetes were hospitalized, of which 41 875 (67.0 %) had diabetes-associated complications. The median cost of hospitalization for diabetic patients was 7996.11 RMB. Prescribed drugs and laboratory tests were two major contributors to hospitalization costs, accounting for 36.2 % and 22.4 %, respectively. Hospitalization costs were significantly associated with LOS, number of complications, age, year of admission, admission status, sex, and medical insurance (P < 0.001). Both hospitalization costs and LOS increased substantially with an increase in the number of complications (P < 0.001). The highest hospitalization costs were seen in those diabetic patients with foot complications. Diabetic complications have a significant effect on increases in hospitalization costs and LOS in patients with type 2 diabetes mellitus. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Heat Shock Proteins in Vascular Diabetic Complications: Review and Future Perspective

PubMed Central

Bellini, Stefania; Barutta, Federica; Imperatore, Luigi; Bruno, Graziella; Gruden, Gabriella

2017-01-01

Heat shock proteins (HSPs) are a large family of proteins highly conserved throughout evolution because of their unique cytoprotective properties. Besides assisting protein refolding and regulating proteostasis under stressful conditions, HSPs also play an important role in protecting cells from oxidative stress, inflammation, and apoptosis. Therefore, HSPs are crucial in counteracting the deleterious effects of hyperglycemia in target organs of diabetes vascular complications. Changes in HSP expression have been demonstrated in diabetic complications and functionally related to hyperglycemia-induced cell injury. Moreover, associations between diabetic complications and altered circulating levels of both HSPs and anti-HSPs have been shown in clinical studies. HSPs thus represent an exciting therapeutic opportunity and might also be valuable as clinical biomarkers. However, this field of research is still in its infancy and further studies in both experimental diabetes and humans are required to gain a full understanding of HSP relevance. In this review, we summarize current knowledge and discuss future perspective. PMID:29240668

It is known that diabetes causes some complications including alterations in lipid profile, hepatic enzyme levels but also it causes oxidative stress. Limonene, a major component of Citrus oils, has important health beneficial effects in lowering the level of oxidative stress due to its antioxidant activity. The aim of this study was to investigate the effects of D-limonene on streptozotocin (STZ)-induced diabetes in Wistar albino rats. For this purpose, DNA damage was evaluated by alkaline comet assay. Changes in the activities of catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR) and glutathione peroxidase (GSHPx) and the levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), total glutathione (GSH), malondialdehyde (MDA), insulin, total bilirubin and BCA protein, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT), high density lipoprotein (HDL), low density lipoprotein (LDL), total cholesterol and triglyceride were also evaluated. D-limonene treatment was found to significantly decrease DNA damage, GR enzyme activities and MDA levels and significantly increase GSH levels and CAT, SOD and GSH-Px enzyme activities and altered lipid and liver enzyme parameters in diabetic rats. According to our results, it seems that D-limonene might have a role in the prevention of the complication of diabetes in rats. Copyright © 2017 Elsevier Ltd. All rights reserved.

Foot complications are considered to be a serious consequence of diabetes mellitus, posing a major medical and economical threat. Identifying the extent of this problem and its risk factors will enable health providers to set up better prevention programs. Saudi National Diabetes Registry (SNDR), being a large database source, would be the best tool to evaluate this problem. This is a cross-sectional study of a cohort of 62,681 patients aged ≥ 25 years from SNDR database, selected for studying foot complications associated with diabetes and related risk factors. The overall prevalence of diabetic foot complications was 3.3% with 95% confidence interval (95% CI) of (3.16%-3.44%), whilst the prevalences of foot ulcer, gangrene, and amputations were 2.05% (1.94%-2.16%), 0.19% (0.16%-0.22%), and 1.06% (0.98%-1.14%), respectively. The prevalence of foot complications increased with age and diabetes duration predominantly amongst the male patients. Diabetic foot is more commonly seen among type 2 patients, although it is more prevalent among type 1 diabetic patients. The Univariate analysis showed Charcot joints, peripheral vascular disease (PVD), neuropathy, diabetes duration ≥ 10 years, insulin use, retinopathy, nephropathy, age ≥ 45 years, cerebral vascular disease (CVD), poor glycemic control, coronary artery disease (CAD), male gender, smoking, and hypertension to be significant risk factors with odds ratio and 95% CI at 42.53 (18.16-99.62), 14.47 (8.99-23.31), 12.06 (10.54-13.80), 7.22 (6.10-8.55), 4.69 (4.28-5.14), 4.45 (4.05-4.89), 2.88 (2.43-3.40), 2.81 (2.31-3.43), 2.24 (1.98-2.45), 2.02 (1.84-2.22), 1.54 (1.29-1.83), and 1.51 (1.38-1.65), respectively. Risk factors for diabetic foot complications are highly prevalent; they have put these complications at a higher rate and warrant primary and secondary prevention programs to minimize morbidity and mortality in addition to economic impact of the complications.

The discovery of endothelial progenitor cells (EPCs) in human peripheral blood advanced the field of cell-based therapeutics for many pathological conditions. Despite the lack of agreement about the existence and characteristics of EPCs, autologous EPC populations represent a novel treatment option for complications requiring therapeutic revascularization and vascular repair. Patients with diabetic complications represent a population of patients that may benefit from cellular therapy yet their broadly dysfunctional cells may limit the feasibility of this approach. Diabetic EPCs have decreased migratory prowess and reduced proliferative capacity and an altered cytokine/ growth factor secretory profile that can accelerates deleterious repair mechanisms rather than support proper vascular repair. Furthermore, the diabetic environment poses additional challenges for the autologous transplantation of cells. The present review is focused on correcting diabetic EPC dysfunction and the challenges involved in the application of cell-based therapies for treatment of diabetic vascular complications. In addition, ex vivo and in vivo functional manipulation(s) of EPCs to overcome these hurdles are discussed. PMID:20299675

The recognition of the importance of diabetes in vascular disease has greatly increased lately. Common risk factors for diabetes-related vascular disease include hyperglycemia, insulin resistance, dyslipidemia, inflammation, hypercoagulability, hypertension, and atherosclerosis. All of these factors contribute to the endothelial dysfunction which generates the diabetic complications, both macro and microvascular. Knowledge of diabetes-related vascular complications and of associated mechanisms it is becoming increasingly important for therapists. The discovery of microparticles (MPs) and their associated microRNAs (miRNAs) have opened new perspectives capturing the attention of basic and clinical scientists for their potential to become new therapeutic targets and clinical biomarkers. MPs known as submicron vesicles generated from membranes of apoptotic or activated cells into circulation have the ability to act as autocrine and paracrine effectors in cell-to-cell communication. They operate as biological vectors modulating the endothelial dysfunction, inflammation, coagulation, angiogenesis, thrombosis, subsequently contributing to the progression of macro and microvascular complications in diabetes. More recently, miRNAs have started to be actively investigated, leading to first exciting reports, which suggest their significant role in vascular physiology and disease. The contribution of MPs and also of their associated miRNAs to the development of vascular complications in diabetes was largely unexplored and undiscussed. In essence, with this review we bring light upon the understanding of impact diabetes has on vascular biology, and the significant role of MPs and MPs associated miRNAs as novel mediators, potential biomarkers and therapeutic targets in vascular complications in diabetes.

Youth with type 1 diabetes face long-term risks of health complications of the disease. Little is known about patients' and parents' knowledge, acquisition of information, and family communication regarding these complications. This paper reports qualitative analyses of parental focus-group discussions of this topic. A total of 47 participants (30 mothers, 14 fathers, and 3 others) representing 33 children between the ages of 8 and 18 years with type 1 diabetes participated in 1 of 13 focus groups. Open-ended questions focused on the type and amount of information about long-term complications presented to parents by health care professionals at different time points, as well as the way that information was presented. Questions also elicited details about parent-child communication and exposure to misconceptions about diabetes complications. Qualitative analysis of the transcribed focus groups revealed that participants experienced significant anxiety about diabetes complications, with a shift from concern about daily management tasks to concern about long-term complications over time. Participants desired a flexible, collaborative educational approach, especially regarding the timing and type of information, relative to the child's age and duration of diabetes. Many parents wanted more sensitive communication and emotional support from health care providers. Motivating children appeared to be a particular challenge; family burnout with regard to diabetes care over time was reported. Knowledge was gained in many ways, yet misinformation was uncommon. Obtaining information about long-term complications is an important process that changes over the course of the disease and with the child's developmental level. More research is needed, especially regarding youth knowledge, learning, and beliefs about diabetes complications.

The incidence of diabetes mellitus has increased drastically over the past few decades. This oxidant-antioxidant imbalance resulting in complication of diabetes mellitus includes macro- and microvascular complications. Resistance to conventional treatment and patient compliance has paved the way to the usage of effective natural products and supplements. Momordica charantia (bitter gourd) is widely consumed in many parts of Malaysia as a vegetable. Momordica charantia (MC) is mainly used in the management of diabetes mellitus. The present review discusses the literature concerning the antidiabetic and antioxidant properties of MC focusing on the complication of diabetes mellitus along with its mode of delivery. We found that among the whole part of MC, its fruit extract has been widely studied, therapeutically. The evidence based analysis of the beneficiary effects of MC on the different organs involved in diabetes complication is also highlighted. This review elucidated an essential understanding of MC based drug delivery system in both clinical and experimental studies and appraised the great potential of the protein based MC extract against diabetes mellitus. The review paper is believed to assist the researchers and medical personnel in treating diabetic associated complications.

Rubio Cabezas, O; Argente Oliver, J

2007-03-01

Diabetes is one of the most common chronic diseases. Type 1, or autoimmune, diabetes accounts for more than 95 % of cases in children and adolescents. Chronic hyperglycemia per se is responsible for the development of several microvascular (retinopathy, nephropathy, neuropathy) and macrovascular complications (ischemic heart disease, cerebrovascular disease, and peripheral vascular disease). Other autoimmune diseases are also more frequent in type 1 diabetic patients. The present review aims to provide an update on some recent advances in this field to aid early detection of these complications and prevent or delay their progression through improved metabolic control.

Diabetic neuropathy and painful diabetic neuropathy: Cinderella complications in South East Asia.

2018-01-01

The most common and debilitating microvascular complication of diabetes is diabetic peripheral neuropathy (DPN), affecting 50-90% of people with diabetes. The major manifestations of DPN are painful (pDPN) and painless diabetic peripheral neuropathy. Painful symptoms, occur in the feet and are worse at night and whilst they alert both the patient and physician, are often misdiagnosed and mismanaged. The devastating presentation of painless neuropathy with loss of sensation is foot ulceration and Charcot foot. The explosion of diabetes, especially in the South East Asian (SEA) region will result in an increasing prevalence of both painful and painless diabetic peripheral neuropathy. PubMed, EMBASE, Medline and Google Scholar databases were searched between 1990 and 2017. This highlights the widely varying prevalence of DPN and pDPN in the World Health Organization (WHO) defined SEA countries and the dearth of published studies, especially in pDPN. We believe this will provide new direction for future research on DPN in the SEA region.

To assess the prevention by primary health care providers of chronic complications of diabetes mellitus according to the complex thinking theoretical approach. Evaluative research based on the complex thinking theoretical approach. The following techniques for data collection were used: interviews with 38 participants; observation in collective and individual appointments; and analysis of medical records of people with diabetes. The triangulation applied for data analysis was the ATLAS.ti software. The prevention and management of chronic complications of diabetes did not meet the requirements set forth by ministerial public policies aimed at this population. Systematic monitoring to prevention of chronic complications showed significant gaps. Primary health care did not consider preventive actions for diabetes mellitus complications. This context was marked by disjunctive, fragmented, and dissociated practices types of care targeted to the totality of the assisted people.

Ethnicity is an important factor in diabetes care. The understanding of its effect in this country may help to improve diabetes care, glycaemic control and diabetic complication rates. This study was to determine the diabetes control profile in relation to complication rates between the three main ethnics group in Malaysia. This nested cross-sectional study was part of the Audit of Diabetes Control and Management (ADCM), an ongoing cohort patient registry focused on diabetes control and management in the primary care setting in Malaysia. This registry registers all diabetes patients aged 18 years old and above. Demographic data, diabetes duration, treatment modalities, as well as various risk factors and diabetes complications are reported. Data was handled by statisticians using STATA version 9. A total of 20330 patients from 54 health centers were registered at the time of this report. The majority were type 2 diabetics (99.1%) of whom 56.6% were female. The mean age was 57.9 years (SD 11.58). Malay accounted for 56.3%, Chinese 19.5% and Indian 22.5%. There were 30.3% who attained HbA1c < 7%. Among three main races more Chinese had HbA1c < 6.5% (Chi-square: X2 = 71.64, p < 0.001), but did not show less complications of nephropathy (Indian suffered significantly more nephropathy, Chi-square: X2 = 168.76, p < 0.001), ischaemic heart disease (Chi-square: X2 = 5.67, p = 0.532) and stroke (Chi-square: X2 =15.38, p = 0.078). This study has again emphasized the existence of ethnic differences in glycaemic control and complication profiles. The Chinese diabetics suffer as many diabetes-related complications despite better glycaemic control. Further studies will need to look into other socio-genetic factors in order to provide a more personalized effective diabetes care.

Background Mexico has been experiencing some of the most rapid shifts ever recorded in dietary and physical activity patterns leading to obesity. Diabetes mellitus has played a crucial role causing nearly 14% of all deaths. We wanted to make a comprehensive study of the role of diabetes in terms of burden of disease, prevalence, cost of diabetes, cost of complications and health policy. Method We review the quantitative data that provides evidence of the extent to which the Mexican health economy is affected by the disease and its complications. We then discuss the current situation of diabetes in Mexico with experts in the field. Results There was a significant increase in the prevalence of diabetes from 1994 to 2006 with rising direct costs (2006: outpatient USD$ 717,764,787, inpatient USD$ 223,581,099) and indirect costs (2005: USD$ 177,220,390), and rising costs of complications (2010: Retinopathy USD$ 10,323,421; Cardiovascular disease USD$ 12,843,134; Nephropathy USD$ 81,814,501; Neuropathy USD$ 2,760,271; Peripheral vascular disease USD$ 2,042,601). The health policy focused on screening and the creation of self-support groups across the country. Conclusions The increasing diabetes mortality and lack of control among diagnosed patients make quality of treatment a major concern in Mexico. The growing prevalence of childhood and adult obesity and the metabolic syndrome suggest that the situation could be even worse in the coming years. The government has reacted strongly with national actions to address the growing burden posed by diabetes. However our research suggests that the prevalence and mortality of diabetes will continue to rise in the future. PMID:23374611

2010-08-01

Diabetes-related microvascular and macrovascular complications, as retinopathy, nephropathy and neuropathy are life-threatening complications in children and adolescents with type 1 diabetes mellitus (T1DM). Risk factors for the development of complications are longer duration of diabetes, older age and puberty. Further risk factors include smoking, hypertension, higher body mass index and dyslipoproteinaemia. Therefore prevention and screening for complications is an important part in the care of children and adolescents with T1DM. Target levels to reduce the risk of microvascular and macrovascular complications in children and adolescents with T1DM are the following: HbA1c<7.5%, lipids in normal range, blood pressure<90th percentile by age, sex and height, BMI<95th percentile, no smoking and physical activity. Screening for retinopathy and microalbuminuria should start from 11 years with two years diabetes duration and from 9 years with 5 years duration and after 2 years diabetes duration in an adolescent. Thereafter screening should be performed annually. Blood pressure should be measured at least annually. Screening for fasting blood lipids should be performed soon after diagnosis in all children with T1DM aged over 12 years. If normal results are obtained, this should be repeated every 5 years.

Background Foot complications are considered to be a serious consequence of diabetes mellitus, posing a major medical and economical threat. Identifying the extent of this problem and its risk factors will enable health providers to set up better prevention programs. Saudi National Diabetes Registry (SNDR), being a large database source, would be the best tool to evaluate this problem. Methods This is a cross-sectional study of a cohort of 62,681 patients aged ≥25 years from SNDR database, selected for studying foot complications associated with diabetes and related risk factors. Results The overall prevalence of diabetic foot complications was 3.3% with 95% confidence interval (95% CI) of (3.16%–3.44%), whilst the prevalences of foot ulcer, gangrene, and amputations were 2.05% (1.94%–2.16%), 0.19% (0.16%–0.22%), and 1.06% (0.98%–1.14%), respectively. The prevalence of foot complications increased with age and diabetes duration predominantly amongst the male patients. Diabetic foot is more commonly seen among type 2 patients, although it is more prevalent among type 1 diabetic patients. The Univariate analysis showed Charcot joints, peripheral vascular disease (PVD), neuropathy, diabetes duration ≥10 years, insulin use, retinopathy, nephropathy, age ≥45 years, cerebral vascular disease (CVD), poor glycemic control, coronary artery disease (CAD), male gender, smoking, and hypertension to be significant risk factors with odds ratio and 95% CI at 42.53 (18.16–99.62), 14.47 (8.99–23.31), 12.06 (10.54–13.80), 7.22 (6.10–8.55), 4.69 (4.28–5.14), 4.45 (4.05–4.89), 2.88 (2.43–3.40), 2.81 (2.31–3.43), 2.24 (1.98–2.45), 2.02 (1.84–2.22), 1.54 (1.29–1.83), and 1.51 (1.38–1.65), respectively. Conclusions Risk factors for diabetic foot complications are highly prevalent; they have put these complications at a higher rate and warrant primary and secondary prevention programs to minimize morbidity and mortality in addition to economic impact

In this paper, we show surface-enhanced Raman spectra (SERS) of serums from type II diabetes mellitus and diabetic complication (coronary disease, glaucoma and cerebral infarction), and analyze the SERS through the multivariate statistical methods of principal component analysis (PCA). In particular, we find that there exist many adenines in these serums, which maybe come from DNA (RNA) damage. The relative intensity of the band at 725±2 cm-1 assigned to adenine is higher for patients than for the healthy volunteers; therefore, it can be used as an important ‘fingerprint’ in order to diagnose these diseases. It is also shown that serums from type II diabetes mellitus group, diabetic complication group and healthy volunteers group can be discriminated by PCA.

Fisetin Lowers Methylglyoxal Dependent Protein Glycation and Limits the Complications of Diabetes

2011-01-01

The elevated glycation of macromolecules by the reactive dicarbonyl and α-oxoaldehyde methylglyoxal (MG) has been associated with diabetes and its complications. We have identified a rare flavone, fisetin, which increases the level and activity of glyoxalase 1, the enzyme required for the removal of MG, as well as the synthesis of its essential co-factor, glutathione. It is shown that fisetin reduces two major complications of diabetes in Akita mice, a model of type 1 diabetes. Although fisetin had no effect on the elevation of blood sugar, it reduced kidney hypertrophy and albuminuria and maintained normal levels of locomotion in the open field test. This correlated with a reduction in proteins glycated by MG in the blood, kidney and brain of fisetin-treated animals along with an increase in glyoxalase 1 enzyme activity and an elevation in the expression of the rate-limiting enzyme for the synthesis of glutathione, a co-factor for glyoxalase 1. The expression of the receptor for advanced glycation end products (RAGE), serum amyloid A and serum C-reactive protein, markers of protein oxidation, glycation and inflammation, were also increased in diabetic Akita mice and reduced by fisetin. It is concluded that fisetin lowers the elevation of MG-protein glycation that is associated with diabetes and ameliorates multiple complications of the disease. Therefore, fisetin or a synthetic derivative may have potential therapeutic use for the treatment of diabetic complications. PMID:21738623

We compared the utility of glycated hemoglobin (HbA 1c ) and oral glucose tolerance (oGTT) in non-diabetic patients for identifying incident diabetes; all-cause mortality; cardiovascular disease (CVD) mortality; CVD, coronary heart disease (CHD), and ischemic stroke events; and diabetes microvascular complications. Data from a New Zealand community setting were prospectively linked to hospitalization, mortality, pharmaceutical and laboratory test results data. After applying exclusion criteria (prior laboratory diagnosis or history of drug treatment for diabetes or hospitalization for diabetes or CVD event), there were 31,148 adults who had an HbA 1c and 2-h 75g oGTT. HbA 1c was measured by ion-exchange high-performance liquid chromatography, and glucose using a commercial enzymatic method. We compared glycemic measures and outcomes using multivariable Cox proportional hazards regression. The median follow-up time was 4years (range 0 to 13). The mean age was 57·6years and 53·0% were male. After adjusting for other glycemic measures (fasting glucose, 2-h glucose and/or HbA 1c where relevant) in addition to age, sex, ethnicity and smoking habit, the hazard ratios for incident diabetes and diabetes complications of retinopathy and nephropathy were highest for 2-h glucose levels, followed by HbA 1c and lastly by fasting glucose. However, all-cause mortality and CHD were significantly associated with HbA 1c concentrations only, and ischemic stroke and CVD events with 2-h glucose only. Circulatory complications showed a stronger association with HbA 1c . Apart from neuropathy, HbA 1c showed stronger associations with outcomes compared to fasting glucose and provides a convenient alternative to an oGTT. Copyright © 2017 Elsevier Inc.

To assess clinical profiles of patients with type 2 diabetes in the United Arab Emirates (UAE), including patterns, frequencies, and risk factors of microvascular and macrovascular complications. Four hundred and ninety patients with type 2 diabetes were enrolled from two major hospitals in Abu Dhabi. The presence of microvascular and macrovascular complications was assessed using logistic regression, and demographic, clinical and laboratory data were collected. Significance was set at p<0.05. Hypertension (83.40%), obesity (90.49%) and dyslipidemia (93.43%) were common type 2 diabetes comorbidities. Most of the patients had relatively poor glycemic control and presented with multiple complications (83.47% of patients had one or more complication), with frequent renal involvement. The most frequent complication was retinopathy (13.26%). However, the pattern of complications varied based on age, where in patients <65 years, a single pattern presented, usually retinopathy, while multiple complications was typically seen in patients >65 years old. Low estimated glomerular filtration rate in combination with disease duration was the most significant risk factor in the development of a diabetic-associated complication especially for coronary artery disease, whereas age, lipid values and waist circumference were significantly associated with the development of diabetic retinopathy. Patients with type 2 diabetes mellitus in the UAE frequently present with comorbidities and complications. Renal disease was found to be the most common comorbidity, while retinopathy was noted as the most common diabetic complication. This emphasizes the need for screening and prevention program toward early, asymptomatic identification of comorbidities and commence treatment, especially for longer disease duration.

This study examined relations between elevated body mass index (BMI) and time to diagnosis with type 2 diabetes mellitus and its complications among older adults in the United States. Data came from the Medicare Current Beneficiary Survey, 1991-2010. A Cox proportional hazard model was used to assess relations between excess BMI at the first Medicare Current Beneficiary Survey interview and time to diabetes mellitus diagnosis, complications, and insulin dependence among Medicare beneficiaries, older than 65 years of age with no prior diabetes mellitus diagnosis, and who were not enrolled in Medicare Advantage (N = 14,657). Among individuals diagnosed as having diabetes mellitus, elevated BMIs were associated with a progressively higher risk of complications from diabetes mellitus. For women with a BMI ≥40, the risk of insulin dependence (hazard ratio [HR] 3.57; 95% confidence interval [CI] 2.36-5.39) was twice that for women with 25 ≤ BMI < 27.5 (HR 1.77; 95% CI 1.33-2.33). A similar pattern was observed in risk of cardiovascular (25 ≤ BMI < 27.5: HR 1.34; 95% CI 1.15-1.54; BMI ≥40: HR 2.45; 95% CI 1.92-3.11), cerebrovascular (25 ≤ BMI < 27.5: HR 1.30; 95% CI 1.06-1.57; BMI ≥40: HR 2.00; 95% CI 1.42-2.81), renal (25 ≤ BMI < 27.5: HR 1.31; 95% CI 1.04-1.63; BMI ≥40: HR 2.23; 95% CI 1.54-3.22), and lower extremity complications (25 ≤ BMI < 27.5: HR 1.41; 95% CI 1.22-1.61; BMI ≥40: HR 2.95; 95% CI 2.35-3.69). Any increase in BMI above normal weight levels is associated with an increased risk of being diagnosed as having complications of diabetes mellitus. For men, the increased risk of these complications occurred at higher BMI levels than in women. Ocular complications occurred at higher BMI levels than other complication types in both men and women.

Diabetes mellitus constitutes a major disease burden globally, and the prevalence of diabetes continues to increase worldwide. We aimed to estimate the burden of cancer associated with type 2 diabetes mellitus in Japan between 2010 and 2030. In this study, we estimated the population attributable fraction of cancer risk associated with type 2 diabetes in 2010 and 2030 using the prevalence estimates of type 2 diabetes in Japan from 1990 to 2030, summary hazard ratios of diabetes and cancer risk from a pooled analysis of eight large-scale Japanese cohort studies, observed incidence/mortality of cancer in 2010 and predicted incidence/mortality for 2030 derived from the age-period-cohort model. Our results showed that between 2010 and 2030, the total numbers of cancer incidence and mortality were predicted to increase by 38.9% and 10.5% in adults aged above 20 years, respectively. In the number of excess incident cancer cases associated with type 2 diabetes, an increase of 26.5% in men and 53.2% in women is expected between 2010 and 2030. The age-specific analysis showed that the population attributable fraction of cancer will increase in adults aged >60 years over time, but will not change in adults aged 20-59 years. In conclusion, this study suggests a modest but steady increase in cancers associated with type 2 diabetes. © 2016 The Authors.

2015-08-01

Gestational diabetes insipidus (GDI) is a rare, self-limited complication of pregnancy. As it is related to excess placental vasopressinase enzyme activity, which is metabolized in the liver, GDI is more common in pregnancies complicated by conditions associated with liver dysfunction. We present a case of a 41-year-old woman at 38 weeks' gestation who presented with pre-eclampsia with severe features, including impaired liver function and renal insufficiency. Following cesarean section she was diagnosed with GDI, which was further complicated by cerebral vasoconstriction as demonstrated by magnetic resonance angiography. This case raises the possibility that cerebral vasoconstriction may be related to the cause of GDI. A high index of suspicion of GDI should be maintained in patients who present with typical signs and symptoms, especially in the setting of pregnancy complications associated with liver dysfunction. © 2015 The Authors.

Aims The control of blood glucose levels, blood pressure (BP), and low-density lipoprotein cholesterol (LDL-C) levels reduces the risk of diabetes complications; however, data are scarce on control status of these factors among workers with diabetes. The present study aimed to estimate the prevalence of participants with diabetes who meet glycated hemoglobin (HbA1c), BP, and LDL-C recommendations, and to investigate correlates of poor glycemic control in a large working population in Japan. Methods The Japan Epidemiology Collaboration on Occupational Health (J-ECOH) Study is an ongoing cohort investigation, consisting mainly of employees in large manufacturing companies. We conducted a cross-sectional analysis of 3,070 employees with diabetes (2,854 men and 216 women) aged 20–69 years who attended periodic health examinations. BP was measured and recorded using different company protocols. Risk factor targets were defined using both American Diabetes Association (ADA) guidelines (HbA1c < 7.0%, BP < 140/90 mmHg, and LDL-C < 100 mg/dL) and Japan Diabetes Society (JDS) guidelines (HbA1c < 7.0%, BP < 130/80 mmHg, and LDL-C < 120 mg/dL). Logistic regression models were used to explore correlates of poor glycemic control (defined as HbA1c ≥ 8.0%). Results The percentages of participants who met ADA (and JDS) targets were 44.9% (44.9%) for HbA1c, 76.6% (36.3%) for BP, 27.1% (56.2%) for LDL-C, and 11.2% (10.8%) for simultaneous control of all three risk factors. Younger age, obesity, smoking, and uncontrolled dyslipidemia were associated with poor glycemic control. The adjusted odds ratio of poor glycemic control was 0.58 (95% confidence interval, 0.46–0.73) for participants with treated but uncontrolled hypertension, and 0.47 (0.33–0.66) for participants with treated and controlled hypertension, as compared with participants without hypertension. There was no significant difference in HbA1c levels between participants with treated but uncontrolled hypertension and

The Diabcare-Asia project was initiated to study the status of diabetes care and prevalence of diabetic complications in Asia and this study was done to evaluate the above in public hospitals in Malaysia and compare to a similar study done in 1998. A total of 19 public hospitals participated in this study from which a total of 1099 patients were included and analysed. The majority of patients (94.8%) had type 2 diabetes mellitus and 66.5% were overweight or obese. As for glycaemic control only 41.0% of the patients had HbA1c < 7% and 18% had FPG < 6.1 mmol/L. As for lipid levels, only 32.0% of the patients had total cholesterol < 4.8 mmol/L; 59.6% had HDL-cholesterol > 1.1 mmol/L and 51.1% had triglycerides < 1.7 mmol/L. Despite the high proportion of patients having dyslipidaemia, only 52.8% of the patients were on lipid lowering therapy. As for blood pressure, 15.0% of the patients had blood pressure < 130/80 mmHg. Although 75.9% of the patients were on antihypertensive medication only 11.3% had blood pressure < 130/80 mmHg. Only 54.8% of patients admitted to adhering to a diabetic diet regularly and 38.9% exercised regularly. As for glucose monitoring, only 26.8% of the patients did home blood glucose monitoring and 1.8% did home urine glucose testing. There was also a high complication rate with the commonest being neuropathy (19.0%) followed by albuminuria (15.7%), background retinopathy (11.1%) and microalbuminuria (6.6%). Compared to the 1998 study, there was some improvement in the percentage of patients achieving target levels and a reduction in the prevalence of complications. In conclusion, the majority of diabetic patients treated at the public hospitals were still not satisfactorily controlled and this was still associated with a high prevalence of complications. There is still an urgent need to educate both patients and health care personnel on the importance of achieving the clinical targets and greater effort must be made to achieve these targets.

Diabetes mellitus (diabetes) increases the risk of acute myocardial infarction, which can result in cardiogenic shock. Data on the relation of diabetes and the occurrence and prognosis of cardiogenic shock postacute myocardial infarction are scant. Among the National Inpatient Sample patients aged ≥18 years and hospitalized for acute myocardial infarction during the 2012-2014 period, we examined the association between diabetes and the incidence and outcomes of cardiogenic shock complicating acute myocardial infarction, using multivariable logistic and linear regression models. Of 1,332,530 hospitalizations for acute myocardial infarction, 72,765 (5.5%) were complicated by cardiogenic shock. In acute myocardial infarction patients, cardiogenic shock incidence was higher among those with vs without diabetes (5.8% vs 5.2%; adjusted odds ratio [aOR] 1.14; 95% confidence interval [CI], 1.11-1.19; P < .001), with 42.8% (n = 31,135) of patients with acute myocardial infarction and cardiogenic shock having diabetes. Diabetic patients were less likely to undergo revascularization (percutaneous coronary intervention or coronary artery bypass grafting) (67.1% vs 68.7%; aOR 0.88; 95% CI, 0.80-0.96; P = .003). Diabetes was associated with higher in-hospital mortality in patients with acute myocardial infarction and cardiogenic shock (37.9% vs 36.8%; aOR 1.18; 95% CI, 1.09-1.28; P < .001). Among survivors, patients with diabetes had a longer hospital stay (mean ± SEM: 11.6 ± 0.16 vs 10.9 ± 0.16 days; adjusted estimate 1.12; 95% CI, 1.06-1.18; P < .001) and were more likely to be discharged to a skilled nursing home or with home health care (56.0% vs 50.5%; aOR 1.19; 95% CI, 1.07-1.33; P = .001). In a large cohort of acute myocardial infarction patients, preexisting diabetes was associated with an increased risk of cardiogenic shock and worse outcomes in those with cardiogenic shock.

Current International Diabetes Federation guidelines recommend a target HbA1c <7.0%, but many people with diabetes worldwide find this difficult to achieve, increasing their risk of developing complications. This publication examines the prevalence of diabetes complications and its association with baseline characteristics in people with type 2 diabetes who participated in the A1chieve study. A1chieve was a 24-week, multinational, open-label, observational study of 66,726 people with type 2 diabetes who had begun using biphasic insulin aspart 30, insulin aspart, or insulin detemir in routine clinical care. Participants were enrolled from 28 countries across four continents (Asia, Africa, Europe and South America). Baseline measurements of disease characteristics included: glycated haemoglobin (HbA1c), fasting (FPG) and post-prandial plasma glucose (PPG), high- and low-density lipoprotein cholesterol (H- or LDL-C), systolic blood pressure (SBP), and body mass index (BMI). Data on complications and use of vascular disease preventative drugs were collected. Complication rates were high (27.2% had macrovascular complications and 53.5% had microvascular complications), particularly in Russia, and use of vascular disease preventative drugs was lower than expected. Age, BMI, diabetes duration, LDL-C, and SBP were positively associated, and HDL-C negatively associated, with macro- and microvascular complications (all p < 0.05). HbA1c and FPG were negatively associated with macrovascular complications (both p < 0.05), which may be linked to the cross-sectional study design. These results suggest a worldwide failure to achieve glycaemic targets. Better diabetes management with earlier initiation and optimisation of insulin regimens (e.g., with insulin analogues in the A1chieve population) may reduce the prevalence of vascular complications, improve the lives of people with diabetes and reduce the burden on healthcare systems.

The prevalence of diabetes mellitus is rising worldwide. When diabetes is uncontrolled, it has dire consequences for health and well-being. However, the role of diet in the origin of diabetes complications is not understood well. This study identifies major dietary patterns among type 2 diabetes patients and its association with diabetes complications in Gaza Strip, Palestine. This cross sectional study was conducted among 1200 previously diagnosed type 2 diabetes mellitus (both genders, aged 20-64 years), patients receiving care in primary healthcare centers in Gaza Strip, Palestine. Dietary patterns were evaluated using a validated semi-quantitative food frequency questionnaire. Additional information regarding demographic and medical history variables was obtained with an interview-based questionnaire. Statistical analysis was performed using SPSS version 20. Two major dietary patterns were identified by factor analysis: Asian-like pattern and sweet-soft drinks-snacks pattern. After adjustment for confounding variables, patients in the lowest tertile of the Asian-like pattern characterized by a high intake of whole grains, potatoes, beans, legumes, vegetables, tomatoes and fruit had a lower odds for (High BP, kidney problems, heart problems, extremities problems and neurological problems), (OR 0.710 CI 95% (.506-.997)), (OR 0.834 CI 95% (.700-.994)), (OR 0.730 CI 95% (.596-.895)), (OR 0.763 CI 95% (.667-.871)) and (OR 0.773 CI 95% (.602-.991)) respectively, (P value <0.05 for all). No significant association was found between the sweet-soft drinks snacks pattern with diabetes complications. The Asian-like pattern may be associated with a lower prevalence of diabetes complications among type 2 diabetes patients.

The effective treatment of diabetes and the prevention of diabetic complications may be improved by a better understanding of the antioxidant function of intracellular defences against oxidative stress. Polymorphisms in antioxidant genes may determine cellular oxidative stress levels as a primary pathogenic role in diabetes and/or in its complications. SOD-2 was investigated in patients with type 1 diabetes mellitus (T1DM) to ascertain if specific genotypes have any protective influences in the pathogenic mechanisms in diabetes and/or in several different complications, including retinopathy, nephropathy and diabetic controls compared to normal healthy controls. 278 (136M:142F) T1DM patients and 135 (72M:63F) normal, healthy controls were investigated for SOD-2 polymorphism in the mitochondrial targeting sequence with Ala/Val (C-9T) substitution. A significant difference in the C-9-T genotype was observed between patients and normal controls but not between diabetic controls and patients with complications. There were significantly more of the diabetic control (DC, n=62) group (11.3%) than the patients with diabetic nephropathy (DN, n=73) (1.4%) with the CC genotype (p=0.03 and χ(2)=4.27, OR=9.16 (1.08complication groups after correction for the number of groups. All groups were in Hardy Weinberg equilibrium. The SNP in SOD-2 results in a substitution of C to T, which causes an amino acid change from alanine to valine. The variation in the SOD-2 leader signal affects the processing efficiency of the enzyme. A significantly greater proportion of the diabetic control group had the CC genotype suggesting antioxidant protection against diabetic nephropathy. The healthy

In Egypt, data on the prevalence of chronic diabetic complications, which are essential for the adjustment of policies and practices related to diabetes care, are scarce. Therefore, the aim of this study was to determine the frequency of chronic complications of diabetes; namely neuropathy, diabetic kidney disease (DKD), retinopathy and peripheral arterial disease (PAD) in newly-diagnosed versus known type 2 diabetic patients. This is a cross-sectional study that is based on a previous household survey conducted on a representative sample of the population of Alexandria, Egypt. This study included 506 consecutive subjects with type 2 diabetes; 323 patients with previously known T2DM and 183 patients with newly diagnosed T2DM (discovered during the survey). For each participant, a focused history was taken. Comprehensive clinical examination was done including fundus examination, foot examination and assessment of ankle brachial index. Laboratory tests included HbAlc, lipids profile, serum creatinine and urinary albumin creatinine ratio (UACR). Peripheral neuropathy was detected in 20% of the studied patients; 29.4% of known patients and 3.3% of newly diagnosed patients (p<0.001). Diabetic kidney disease was detected in 33.2% of the studied patients; 46.1% of known patients and 10.4% of newly diagnosed patients (p<0.001). Diabetic retinopathy was detected in 34.6% of the studied patients; 48.3% of known patients and 10.4% of newly diagnosed patients (p<0.001). Peripheral arterial disease was detected in 32.6% of the studied patients; 45.5% of known patients and 9.8% of newly diagnosed patients (p<0.001). In patients with known diabetes, the presence of any of the studied complications (neuropathy, diabetic kidney disease, retinopathy or PAD) was significantly associated with the presence of all other complications (p< 0.001). In patients with newly-diagnosed diabetes, the presence of diabetic kidney disease was significantly associated with the presence of

Background. Dendrobium officinale (DO) Kimura et Migo is a precious Chinese herb that is considered beneficial for health due to its antioxidant and antidiabetes properties, and so on. In this research, we try to determine the preventive effect of DO on the early complications of STZ-induced diabetic rats. Methods. Type 1 diabetic rats were produced with a single intraperitoneal injection of STZ (50 mg/kg). DO (1 g/kg/day) was then orally administered for 5 weeks. Blood glucose, TC, TG, BUN, CREA, and GSH-PX levels were determined, and electroretinographic activity and hypoalgesia were investigated. Pathological sections of the eyes, hearts, aortas, kidneys, and livers were analyzed. Results. Treatment with DO significantly attenuated the serum levels of TC, TG, BUN, and CREA, markedly increased the amplitudes of ERG a- and b-waves and Ops, and reduced the hypoalgesia and histopathological changes of vital organs induced by hyperglycemia. The protective effect of DO in diabetic rats may be associated with its antioxidant activity, as evidenced by the marked increase in the serum level of glutathione peroxidase. However, DO had no significant effect on blood glucose levels and bodyweight of diabetic rats. Conclusions. DO supplementation is an effective treatment to prevent STZ-induced diabetic complications.

To obtain epidemiological data on the prevalence of predefined stages of diabetic microvascular complications from a representative cross-section of patients with existing microvascular complications of type 1 or type 2 diabetes in Germany. A cross-sectional, retrospective study of medical records of 705 type 1 and 1910 type 2 adult diabetic patients with a diagnosis of retinopathy and/or peripheral neuropathy and/or nephropathy before 2002 and treated in 2002 in Germany. Of 376 patients with type 1 diabetes having retinopathy, 59.3% had mild or moderate non-proliferative retinopathy without macular oedema, 27.1% had macular oedema, and 13.6% had severe retinopathy without macular oedema. In 862 patients with type 2 diabetes, the distribution of retinopathy/maculopathy classes was 56.8%, 35.5%, and 7.7%, respectively. Of 381 type 1 diabetes patients with observed peripheral neuropathy, 81.4% had sensorimotor neuropathy, 8.9% had diabetic foot conditions, and 9.7% had lower extremity amputations because of diabetes. In 1005 patients with type 2 diabetes, the distribution of neuropathy classes was 78.2%, 12.1%, and 9.7%, respectively. The proportions of patients with renal insufficiency in type 1 and type 2 diabetes groups were 15.3% versus 13.5%, respectively. The study suggests that there are considerable proportions of patients with progressive stages of microvascular complications related to type 1 and type 2 diabetes in Germany. This underlines the importance of improvement of optimal quality of care and frequent screening for preventing late diabetic microvascular complications and the necessity of effective intervention strategies to tackle this major public health problem.

Gestational diabetes mellitus and pregestational diabetes mellitus constitute carbohydrate metabolism disorders, which, if not diagnosed and adequately treated, lead to serious and often life-threatening pregnancy complications. According to a recently formulated hypothesis, some diabetes-related complications, such as fetal macrosomia, may be the result of disturbances in the transplacental transport of nutrients-in particular, excessive maternal-fetal glucose transfer. Throughout pregnancy, glucose flux across the placenta is mediated by the group of facilitative glucose transporters (GLUT), the expression of which in different placental compartments is the precondition for effective glucose uptake from maternal blood and its subsequent transfer to the fetal circulation. In diabetes-complicated pregnancies, the location, expression and activity of glucose transporters are modified to an extent that results in alterations in the maternal-fetal glucose exchange, potentially leading to an excessive supply of energy substrates to the fetus. This paper reviews the literature on the expression and activity of glucose transporter proteins-GLUT-1, GLUT-3, GLUT-4, GLUT-8, GLUT-9 and GLUT-12-in the human placenta, with a special focus on diabetes-complicated pregnancy. The characteristics of transporters in conditions of maternal normoglycemia and modifications occurring in the diabetic placenta are summarized, and the factors responsible for the regulation of the expression of selected isoforms are described. Finally, the impact of alterations in the placental expression of the aforementioned members of the GLUT family on intrauterine fetal development in pregnancies complicated by diabetes mellitus is discussed.

Significant morbidity and mortality among patients with diabetes mellitus result largely from a greatly increased incidence of microvascular complications. Proliferative diabetic retinopathy (PDR) and end stage renal disease (ESRD) are two of the most common and severe microvascular complications of diabetes. A high concordance exists in the development of PDR and ESRD in diabetic patients, as well as strong familial aggregation of these complications, suggesting a common underlying genetic mechanism. However, the precise gene(s) and genetic variant(s) involved remain largely unknown. Erythropoietin (EPO) is a potent angiogenic factor observed in the diabetic human and mouse eye. By a combination of case–control association and functional studies, we demonstrate that the T allele of SNP rs1617640 in the promoter of the EPO gene is significantly associated with PDR and ESRD in three European-American cohorts [Utah: P = 1.91 × 10−3; Genetics of Kidneys in Diabetes (GoKinD) Study: P = 2.66 × 10−8; and Boston: P = 2.1 × 10−2]. The EPO concentration in human vitreous body was 7.5-fold higher in normal subjects with the TT risk genotype than in those with the GG genotype. Computational analysis suggests that the risk allele (T) of rs1617640 creates a matrix match with the EVI1/MEL1 or AP1 binding site, accounting for an observed 25-fold enhancement of luciferase reporter expression as compared with the G allele. These results suggest that rs1617640 in the EPO promoter is significantly associated with PDR and ESRD. This study identifies a disease risk-associated gene and potential pathway mediating severe diabetic microvascular complications. PMID:18458324

Chronic or intermittent hyperglycemia is associated with the development of diabetic complications. Several signaling pathways can be altered by having hyperglycemia in different tissues, producing oxidative stress, the formation of advanced glycation end products (AGEs), as well as the secretion of the pro-inflammatory cytokines and cellular death (pathological autophagy and/or apoptosis). However, the signaling pathways that are directly triggered by hyperglycemia appear to have a pivotal role in diabetic complications due to the production of reactive oxygen species (ROS), oxidative stress, and cellular death. The present review will discuss the role of cellular death in diabetic complications, and it will suggest the cause and the consequences between the hyperglycemia-induced signaling pathways and cell death. The signaling pathways discussed in this review are to be described step-by-step, together with their respective inhibitors. They involve diacylglycerol, the activation of protein kinase C (PKC) and NADPH-oxidase system, and the consequent production of ROS. This was initially entitled the "dangerous metabolic route in diabetes". The historical usages and the recent advancement of new drugs in controlling possible therapeutical targets have been highlighted, in order to evaluate the evolution of knowledge in this sensitive area. It has recently been shown that the metabolic responses to stimuli (i.e., hyperglycemia) involve an integrated network of signaling pathways, in order to define the exact responses. Certain new drugs have been experimentally tested-or suggested and proposed-for their ability to modulate the possible biochemical therapeutical targets for the downregulation of retinopathy, nephropathy, neuropathy, heart disease, angiogenesis, oxidative stress, and cellular death. The aim of this study was to critically and didactically evaluate the exact steps of these signaling pathways and hence mark the indicated sites for the actions of such

We examined changes in prevalence of diabetic microvascular/macrovascular complications and diabetes care indicators for adults in Japan with type 2 and type 1 diabetes over one decade. Two independent cohorts were recruited with the same inclusion criteria in 2004 (cohort 1: 3319 with type 2 and 286 with type 1 diabetes) and in 2014 (cohort 2: 3932 with type 2 and 308 with type 1 diabetes). Prevalence of complications and care indicators including achieving treatment targets for glycemia, blood pressure, lipid control, body mass index (BMI), and smoking were compared. In addition, patients in cohort 1 were re-examined in 2014 and their data were compared with the baseline data of each cohort. In type 2 diabetes, the prevalence of nephropathy, retinopathy, neuropathy, chronic kidney disease, current smoking and stroke significantly decreased, with improvements in achieving treatment target rates in cohort 2 two as compared with cohort 1. In type 1 diabetes, the prevalence of nephropathy, retinopathy, chronic kidney disease, and hemoglobin A 1C values significantly decreased. Decreases in prevalence of microvascular complications in type 2 diabetes were similarly found in each age-matched and sex-matched group, whereas younger patients exhibited marked increase in BMI and lower treatment target achieving rates compared with elderly patients. Regarding normoalbuminuric renal impairment, only a slight increase in the prevalence was observed both in type 2 and type 1 diabetes. In cohort 1, re-examined in 2014, care indicators were significantly improved from 2004, while complications increased with getting 10 years older. We observed declining trends of diabetic microvascular complications with improvement in diabetes care indicators in type 2 and type 1 diabetes. Younger patients with type 2 diabetes exhibited marked increase in BMI and lower rates of achieving treatment targets compared with elderly patients, which remains a concern.

A number of metabolic conditions, including hypoglycemia, high blood pressure (HBP), dyslipidemia, nerve damage and amputation, and vision problems, occur as a result of uncontrolled blood glucose levels over a prolonged period of time. The different components of diabetic complications are not independent but rather interdependent of each other, rendering the disease difficult to diagnose and control. The underlying pathogenesis of those components cannot be easily elucidated because of the heterogeneous, polygenic, and multifactorial nature of the disease. Metabonomics offers a snapshot of distinct biochemical variations that may reflect the unique metabolic phenotype under pathophysiological conditions. Here we report a mass-spectrometry-based metabonomic study designed to identify the distinct metabolic changes associated with several complications of type 2 diabetes mellitus (T2DM). The 292 patients recruited in the study were divided into five groups, including T2DM with HBP, T2DM with nonalcoholic fatty liver disease (NAFLD), T2DM with HBP and NAFLD, T2DM with HBP and coronary heart disease (CHD), and T2DM with HBP, NAFLD, and CHD. Serum differential metabolites were identified in each group of T2DM complication, mainly involving bile acid, fatty acid, amino acid, lipid, carbohydrate, steroids metabolism, and tricarboxylic acids cycle. These broad-spectrum metabolic changes emphasize the complex abnormalities present among these complications with elevated blood glucose levels, providing a novel strategy for stratifying patients with T2DM complications using blood-based metabolite markers.

Diabetes mellitus is estimated to affect ∼24 million people in the United States and more than 150 million people worldwide. There are numerous end organ complications of diabetes, the onset of which can be delayed by early diagnosis and treatment. Although assays for diabetes are well founded, tests for its complications lack sufficient specificity and sensitivity to adequately guide these treatment options. In our study, we employed a streptozotocin-induced rat model of diabetes to determine changes in urinary protein profiles that occur during the initial response to the attendant hyperglycemia (e.g. the first two months) with the goal of developing a reliable and reproducible method of analyzing multiple urine samples as well as providing clues to early markers of disease progression. After filtration and buffer exchange, urinary proteins were digested with a specific protease, and the relative amounts of several thousand peptides were compared across rat urine samples representing various times after administration of drug or sham control. Extensive data analysis, including imputation of missing values and normalization of all data was followed by ANOVA analysis to discover peptides that were significantly changing as a function of time, treatment and interaction of the two variables. The data demonstrated significant differences in protein abundance in urine before observable pathophysiological changes occur in this animal model and as function of the measured variables. These included decreases in relative abundance of major urinary protein precursor and increases in pro-alpha collagen, the expression of which is known to be regulated by circulating levels of insulin and/or glucose. Peptides from these proteins represent potential biomarkers, which can be used to stage urogenital complications from diabetes. The expression changes of a pro-alpha 1 collagen peptide was also confirmed via selected reaction monitoring. PMID:19497846

Transsphenoidal surgery (TSS) has emerged as the standard approach for pituitary resection due to its minimally invasive nature. There has been little analysis examining the impact of diabetes mellitus (DM) on patients undergoing TSS. In this study, we characterize DM's association with postoperative TSS complications. In addition to analysis of associated charges and patient demographics, we performed comparison of complication rates between DM and non-DM patients who have undergone TSS in recent years. The Nationwide Inpatient Sample, a database encompassing nearly 8 million inpatient hospitalizations, was evaluated for patients undergoing TSS from 2002 to 2010. Of 12,938 TSS patients, 2,173 (16.8%) had a DM diagnosis. The non-DM cohort was younger (50.1 y ± 16.6SD vs. 56.8 y ± 14.1; P < 0.001) and had shorter hospitalizations and lesser charges. DM patients had a greater incidence of pulmonary, cardiac, urinary/renal, and fluid/electrolyte complications, and had a lesser incidence of diabetes insipidus (P < 0.05). Upon controlling for age, the greater incidence of pulmonary and fluid/electrolyte complications was present only among patients < 60 years of age. Higher occurrence of cerebrospinal fluid rhinorrhea was noted among black diabetics when compared to non-DM blacks. DM is associated with greater length of stay and hospital charges among TSS patients. DM patients undergoing TSS have a significantly greater incidence of pulmonary and fluid/electrolyte complications among patients under the age of 60, and greater risk for urinary/renal complications across all ages. Despite a theoretical concern due to an impaired wound-healing in DM patients, association with cerebrospinal fluid rhinorrhea was only noted among black diabetics. 2C. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

The mechanisms underlying progression of type 2 diabetes are complex and varied. Recent studies indicated that oxidative stress provided a new sight. To further assess the relationship between nucleic acid oxidation and complications in patients with type 2 diabetes and explore its possible molecular mechanisms, we studied 1316 subjects, including 633 type 2 diabetes patients and 683 age- and sex-matched healthy controls. Urinary levels of DNA oxidation marker 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) and RNA oxidation marker 8-oxo-7,8-dihydroguanosine (8-oxoGuo) were measured by ultraperformance liquid chromatography and mass spectrometry (UPLC-MS/MS). Serum glucose, HbA1c, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides (TG) were also determined. The results showed significantly elevated levels of both the urinary 8-oxodGuo and 8-oxoGuo in diabetes patients with/without complications compared with age-matched healthy control subjects (p = 0.02 and p < 0.001, resp.). Patients with complications, especially macrovascular complications, exhibited higher levels of 8-oxoGuo than those without complications, while there was no difference in the concentrations of serum glucose and lipids. The finding indicates the role for oxidative damage to DNA and RNA, as a molecular mechanism contributing to the progression of type 2 diabetes. Elevated levels of 8-oxoGuo may be a risk factor for type 2 diabetes complications, especially in diabetic macrovascular complications.

To evaluate the frequency of periodontal disease in a group of patients with type 1 diabetes mellitus and its relationship with diabetic metabolic control, duration and complications. A comparison was made of periodontal parameters (plaque index, bleeding index, pocket depth and attachment loss) in a group of diabetic patients versus a group of non-diabetics (n=20). Statistical analysis was performed to evaluate the relationship between periodontal parameters and degree of metabolic control, the duration of the disease and the appearance of complications. Diabetics had greater bleeding index (p<0.001), probing pocket depth (p<0.001) and clinical attachment level (p=0.001). Patients diagnosed for diabetes for shorter duration of time (4-7 years) showed bleeding index-disease severity correlation to be 1.760 ± 0.434. Patients with type 1 diabetes have increased periodontal disease susceptibility. Periodontal inflammation is greatly increased in subjects with longer disease course, poor metabolic control and diabetic complications. Copyright © 2013 Diabetes India. Published by Elsevier Ltd.

The goal of this study was to identify association between the continuity of ambulatory care of diabetes patients in South Korea (hereafter Korea) and the incidence of macrovascular complications of diabetes, using claims data compiled by the National Health Insurance Services of Korea. This study was conducted retrospectively. The subjects of the study were 43 002 patients diagnosed with diabetes in 2007, who were over 30 years of age, and had insurance claim data from 2008. The macrovascular complications of diabetes mellitus were limited to ischemic heart disease and ischemic stroke. We compared the characteristics of the patients in whom macrovascular complications occurred from 2009 to 2012 to the characteristics of the patients who had no such complications. Multiple logistic regression was used to assess the effects of continuity of ambulatory care on diabetic macrovascular complications. The continuity of ambulatory diabetes care was estimated by metrics such as the medication possession ratio, the quarterly continuity of care and the number of clinics that were visited. Patients with macrovascular complications showed statistically significant differences regarding sex, age, comorbidities, hypertension, dyslipidemia and continuity of ambulatory diabetes care. Visiting a lower number of clinics reduced the odds ratio for macrovascular complications of diabetes. A medication possession ratio below 80% was associated with an increased odds ratio for macrovascular complications, but this result was of borderline statistical significance. Diabetes care by regular health care providers was found to be associated with a lower occurrence of diabetic macrovascular complications. This result has policy implications for the Korean health care system, in which the delivery system does not work properly.

Potential of Dietary Non-Provitamin A Carotenoids in the Prevention and Treatment of Diabetic Microvascular Complications12

Diabetes is a chronic metabolic disease that affects a substantial part of the population around the world. Whether type I or type II, this disease has serious macro- and microvascular complications that constitute the primary cause of death in diabetic patients. Microvascular complications include diabetic retinopathy, nephropathy, and neuropathy. Although these complications are clinically and etiologically diverse, they share a common factor: glucose-induced damage. In the progression of diabetic complications, oxidative stress, inflammation, and the formation of glycation end products play an important role. Previous studies have shown that a healthy diet is vital in preventing these complications; in particular, the intake of antioxidants has been studied for their potential effect in ameliorating hyperglycemic injuries. Carotenoids are lipid-soluble pigments synthesized by plants, bacteria, and some kinds of algae that are responsible for the yellow, red, and orange colors in food. These compounds are part of the antioxidant machinery in plants and have also shown their efficacy in quenching free radicals, scavenging reactive oxygen species, modulating gene expression, and reducing inflammation in vitro and in vivo, showing that they can potentially be used as part of a preventive strategy for metabolic disorders, including diabetes and its related complications. This review highlights the potential protective effects of 4 non-provitamin A carotenoids—lutein, zeaxanthin, lycopene, and astaxanthin—in the development and progression of diabetic microvascular complications.

A lower incidence of cardiovascular events has been reported in type 2 diabetes patients treated with insulin analogs (IAs). Corresponding data on people affected by type 1 diabetes are not available yet. We investigated demographic and clinical data from 509 type 1 diabetics, who were treated in an outpatient clinic from 2006 to 2012. Multiple logistic regression was used to investigate the relationship between the type of insulin treatment and the prevalence of cardiovascular (CV) complications, that is, presence of coronary heart, cerebrovascular and peripheral arterial diseases, adjusting for potential confounders. Results from multiple logistic regression revealed that patients with impaired renal function [estimated glomerular filtration rate (eGFR) < 90 ml/min] show lower CV complication rates when treated with IAs (25%) compared with patients treated with human insulin (HI; 28%) and HI/IA (38%, p = 0.06). CV complication rates in the complete patient collective amounted to 17% (IA), 21% (HI) and 21% (HI/IA, p = 0.08). Examination of CV complications according to the type of IA revealed the lowest complication rates in type 1 diabetics treated with insulin lispro (5.9%) and glargine (16%). However, complication rate differences among insulin treatments did not reach statistical significance. The present cross-sectional study shows a borderline significantly lower CV morbidity in people with type 1 diabetes and impaired renal function when treated with IA compared with HI treatment after adjustment for multiple potential confounders [odds ratio (OR) = 0.78, which translates into a 22% lower complication rate]. Validation of these preliminary findings in confirmatory, prospective studies may have important clinical implications.

To determine the association of verbal intelligence, a core constituent of health literacy, with diabetic complications and walking speed in people with Type 2 diabetes. This study was performed in 228 people with Type 2 diabetes participating in the Maastricht Study, a population-based cohort study. We examined the cross-sectional associations of score on the vocabulary test of the Groningen Intelligence Test with: 1) determinants of diabetic complications (HbA 1c , blood pressure and lipid level); 2) diabetic complications: chronic kidney disease, neuropathic pain, self-reported history of cardiovascular disease and carotid intima-media thickness; and 3) walking speed. Analyses were performed using linear regression and adjusted in separate models for potential confounders and mediators. Significant age- and sex-adjusted associations were additionally adjusted for educational level in a separate model. After full adjustment, lower verbal intelligence was associated with the presence of neuropathic pain [odds ratio (OR) 1.18, 95% CI 1.02;1.36], cardiovascular disease (OR 1.14, 95% CI 1.01;1.30), and slower walking speed (regression coefficient -0.011 m/s, 95% CI -0.021; -0.002 m/s). These associations were largely explained by education. Verbal intelligence was not associated with blood pressure, glycaemic control, lipid control, chronic kidney disease or carotid intima-media thickness. Lower verbal intelligence was associated with the presence of some diabetic complications and with a slower walking speed, a measure of physical functioning. Educational level largely explained these associations. This implies that clinicians should be aware of the educational level of people with diabetes and should provide information at a level of complexity tailored to the patient. © 2016 Diabetes UK.

Protective Role of Sodium-Glucose Co-Transporter 2 Inhibition Against Vascular Complications in Diabetes.

PubMed

Yamagishi, Sho-ichi; Matsui, Takanori

2016-04-01

Diabetic micro- and macroangiopathy are devastating vascular complications that could account for disabilities and high mortality rate in patients with diabetes. Indeed, diabetic nephropathy and retinopathy are the leading causes of end-stage renal failure and acquired blindness, respectively, and atherosclerotic cardiovascular diseases (CVD) accounts for about 60% of death in diabetic subjects. As a result, the average life span of diabetic patients is about 10-15 years shorter than that of non-diabetic subjects. Furthermore, tight blood glucose control might have no more than a marginal impact on CVD in general and on all-cause mortality in particular in diabetes. Therefore, therapeutic strategies that target vascular complications in diabetes need to be developed. Recently, selective inhibition of sodium-glucose co-transporter 2 (SGLT2) has been proposed as a potential therapeutic target for the treatment of patients with diabetes because of low risk of hypoglycemia and no weight gain. Because 90% of glucose filtered by the glomerulus is reabsorbed by a low-affinity/high-capacity SGLT2 expressed in the S1 and S2 segments of the proximal tubule, blockade of SGLT2 promotes urinary glucose excretion and as a result improves hyperglycemia in an insulin-independent manner. Moreover, we have shown that SGLT2-mediated glucose overload to tubular cells could elicit inflammatory and pro-apoptotic reactions in this cell, being directly involved in diabetic nephropathy. In addition, several clinical studies have also shown that SGLT2 inhibitors could reduce blood pressure, body weight, and serum uric acid levels and ameliorate cardiovascular risk in patients with diabetes. This review summarizes the pathophysiological role of SGLT2 in vascular complications in diabetes and its potential therapeutic interventions.

The Epidemiology of Diabetes Interventions and Complications (EDIC) study, an observational follow-up of the Diabetes Control and Complications Trial (DCCT) type 1 diabetes cohort, measured coronary artery calcification (CAC), an index of atherosclerosis, with computed tomography (CT) in 1,205 EDIC patients at ~7–9 years after the end of the DCCT. We examined the influence of the 6.5 years of prior conventional versus intensive diabetes treatment during the DCCT, as well as the effects of cardiovascular disease risk factors, on CAC. The prevalences of CAC >0 and >200 Agatston units were 31.0 and 8.5%, respectively. Compared with the conventional treatment group, the intensive group had significantly lower geometric mean CAC scores and a lower prevalence of CAC >0 in the primary retinopathy prevention cohort, but not in the secondary intervention cohort, and a lower prevalence of CAC >200 in the combined cohorts. Waist-to-hip ratio, smoking, hypertension, and hypercholesterolemia, before or at the time of CT, were significantly associated with CAC in univariate and multivariate analyses. CAC was associated with mean HbA1c (A1C) levels before enrollment, during the DCCT, and during the EDIC study. Prior intensive diabetes treatment during the DCCT was associated with less atherosclerosis, largely because of reduced levels of A1C during the DCCT. PMID:17130504

The purpose of this study was to analyze the outcomes of major lower extremity amputations (MLEAs) in a series, including diabetic patients, with the aim to study whether diabetes mellitus is a risk factor of in-hospital mortality and perioperative complications. A retrospective analysis of 283 MLEAs (221 of these patients were diabetic and 62 were nondiabetic) performed between January 1, 1998, and December 31, 2008, at the General Surgery Department and Diabetic Foot Unit of La Paloma Hospital in Las Palmas de Gran Canaria (Canary Islands) was done. The significant risk factors of mortality were >" xbd="324" xhg="301" ybd="1481" yhg="1446"/>75 years of age (odds ratio [OR] = 4.1, 95% confidence interval [CI] = 1.4-11.7), postoperative cardiac complications (OR = 12.3, 95% CI = 3.7-40.2) and postoperative respiratory complications (OR = 3.8, 95% CI = 1.0-13.3). No statistically significant risk factors were found related to the presence of systemic and wound-related complications. In diabetic patients, the significant risk factors of mortality were postoperative cardiological complications (OR = 13.6, 95% CI = 3.1-59.6), postoperative respiratory complications (OR = 5.9, 95% CI = 1.0-35.5), and first episode of amputation (OR = 5.9, 95% CI = 1.4-24.3). There were no statistically significant differences in the outcome of major amputations between diabetic and nondiabetic patients. Hospital stay was significantly longer in diabetic patients (P < .01) though when the patients with diabetic foot infections were excluded, this difference was not found.

Matricaria chamomilla L., known as "chamomile", has been used as an herbal tea or supplementary food all over the world. We investigated the effects of chamomile hot water extract and its major components on the prevention of hyperglycemia and the protection or improvement of diabetic complications in diabetes mellitus. Hot water extract, esculetin (3) and quercetin (7) have been found to show moderate inhibition of sucrase with IC50 values of 0.9 mg/mL and 72 and 71 microM, respectively. In a sucrose-loading test, the administration of esculetin (50 mg/kg body weight) fully suppressed hyperglycemia after 15 and 30 min, but the extract (500 mg/kg body weight) and quercetin (50 mg/kg body weight) were less effective. On the other hand, a long-term feed test (21 days) using a streptozotocin-induced rat diabetes model revealed that the same doses of extract and quercetin showed significant suppression of blood glucose levels. It was also found that these samples increased the liver glycogen levels. Moreover, chamomile extract showed potent inhibition against aldose reductase (ALR2), with an IC50 value of 16.9 microg/mL, and its components, umbelliferone (1), esculetin (3), luteolin (6), and quercetin (7), could significantly inhibit the accumulation of sorbitol in human erythrocytes. These results clearly suggested that daily consumption of chamomile tea with meals could contribute to the prevention of the progress of hyperglycemia and diabetic complications.

Type 2 Diabetes Mellitus is a serious health problem. In the year 2030 it will affect 366 million people around the world. Evaluate the effectiveness of a mixed intervention and reducing the amount and seriousness of acute complications in diabetics from our Health Area. Protocols of action as well as information documents were produced. Diabetes Unit coordinated educational activities in the different support levels of the Area VII of Murcia. Information talks were provided for the people in charge of the Diabetes Unit in every Care Center and Service of the Health Area. Personalized training was provided for patients treated in the different Care levels. The study comprised three stages. Information leaflets were spread and talks offered to the patient regarding in house handling of hypo and hyper glycemia. A reduction of 39% of the emergencies due to acute non complicated diabetes was achieved, as well as a reduction of 47.6% of hospital admissions. There was a reduction of 67.8% of the amount of total hospital stays for the group of patients under 35 years who were admitted into the hospital due to type 1 or 2 diabetes mellitus that didn't show any complications (GRD295). There was a reduction of more than thirty percent in the emergencies due to acute decompensations in the disease and a significant reduction in the avoidable hospital stays in the young adult, thus improving the patients' life quality and reducing the social cost of the diabetic patient.

Costs associated with diabetes represent a large burden for patients and the health-care system. However, few studies examined the costs for diabetes treatment in adults with type 1 diabetes (T1DM). This analysis was aimed to assess the costs of treatment associated with T1DM among adults in Italy from the national health-care system perspective. Data were collected using a questionnaire assessing resource consumption retrospectively (drugs, visits, diagnostics, hospitalisations and self-monitoring of blood glucose (SMBG)). One-year costs were calculated for the 12 months preceding the survey. Cost estimation, referred to 2006, was carried out using univariate and multivariate Poisson regression models. Fifty-eight centres enrolled 1193 patients (49.5% women; aged between 18 and 55 years, average diabetes duration was 16.1 ± 9.8 years). The average annual cost for an adult patient with TDM1 was € 2450 (95% confidence interval (CI): 2358-2544). Insulin therapy and SMBG accounted together for 71.2% of total costs (35.6% and 35.6%, respectively); the remainder was shared by hospitalisations (18%), visits (4.0%), diagnostics (3.9%) and other drugs (2.9%). Univariate analyses showed that the presence of complications was associated with excess of costs, mainly related to the hospitalisation and drugs. Multivariate analyses confirmed these results showing that the presence of micro-vascular plus macrovascular complications doubles the cost of treatment. Strategies of care for T1DM that can improve disease management and prevent or delay the onset of complications could represent the most important tool to reduce costs in the long term while improving clinical outcomes and quality of life.

There have been differences of opinion among authors concening in the levels of red cell 2,3-diphosphoglycerate (2,3-DPG) and nucleotides in nonacidotic diabetic patients. Our data suggest that abnormal levels of 2, 3-DPG in diabetic patients are related to the presence of vascular complications and not to the duration of the disease per sec. 2,3-DPG levels are normal in diabetic patients with no evidence of vascular complications (group A). In ambulatory patients with vascular complications (group B), significantly higher levels of 2,3-DPG are found than in normal subjects and patients in group A. In hospitalized diabetic patients with active peripheral vascular complications (group C), levels of 2,3-DPG are likewise significantly increased over those of normal subjects and patients of group A. 2,3-DPG was found to be significantly elevated in patients of group C as compared with group B. 2,3-DPG levels in venous blood from infected legs as compared with those of the peripheral venous blood were not significantly different, thereby ruling out local factors. There were no differences in the blood lactate levels in any of the group studied. The elevation of the 2,3-DPG levels may be a reflection of attempted red blood cell compensation for tissue hypoxia in the diabetic with vascular disease.

To assess the prevalence of microvascular and macrovascular complications of type 2 diabetes (T2DM) among Palestinians. 1308 diagnosed T2DM attending four main Primary Health Care Clinics on the Southern West Bank of Palestine examined by a Mobile Diabetes Clinic team. All diabetes patients visiting the clinics during a one-month period for each clinic were included. Interviews, anthropometric measurements, physical examination, and laboratory tests: HbA1c, lipid profile, and kidney function tests analyzed in a central laboratory were obtained RESULTS: 1308 diabetes patients, including 839 females (64%), with a mean age of 57 years (SD=8.7), and mean diabetes duration 7.1 years(SD=6.25), participated. 95.3% presented as overweight (BMI >25kg/m 2 ) or obese (BMI>30kg/m 2 ) with mean BMI of 33.46 (SD=5.95). The mean HbA1c (tested in 1221 patients) was 9.21(SD=2). Only 16.1% had HbA1c <7.0%. Hypertension (blood pressure>140/90mmHg) were found in 23%, and dyslipidemia (total cholesterol>200mg/dl) was present in 37.3% of patients. 213(16.3%) had a history of the macrovascular disease (previous myocardial infarction or stroke), and 290 (25.9%) had microvascular complications. Moreover, 40 (4.9%) had advanced kidney disease with serum creatinine>1.4mg/dl. The present cross-sectional study shows poor glycemic control in Palestine, while blood pressure and lipids are less poorly controlled. The study emphasizes the need to optimize the glucose-lowering treatment and to implement diabetes care program that could face the challenge of high uncontrolled diabetes as well as complications of diabetes.

To assess the association of anthropometric measurements with neonatal complications in macrosomic newborns of non-diabetic mothers. Retrospective cohort study. All liveborn, singleton, full term newborns with birth weight ≥4000 g born to non-diabetic mothers at a tertiary medical centre in 1995-2005 (n=2766, study group) were matched to the next born, healthy, full term infant with a birth weight of 3000-4000 g (control group). Exclusion criteria were multiple birth, congenital infection, major malformations and pregnancy complications. Data collection by file review. Complication rates were compared between study and control groups and between symmetric and asymmetric macrosomic newborns, defined by weight/length ratio (WLR), Body Mass Index and Ponderal Index. The 2766 non-diabetic macrosomic infants identified were matched to 2766 control infants. The macrosomic group had higher rates of hypoglycaemia (1.2% vs 0.5%, p=0.008), transient tachypnoea of the newborn (1.5% vs 0.5%, p<0.001), hyperthermia (0.6% vs 0.1%, p=0.012), and birth trauma (2% vs 0.7%, p<0.001), with no cases of symptomatic polycythaemia, and only one case of hypoglycaemia. Hypoglycaemia was positively associated with birth weight. It was significantly higher in the asymmetric than the symmetric macrosomic newborns, defined by WLR (1.7% vs 0.3%, p<0.001). Macrosomic infants of non-diabetic mothers are at increased risk of neonatal complications. However, routine measurements of haematocrit and calcium may not be necessary. Symmetric macrosomic infants (by WLR) have a similar rate of hypoglycaemia as normal-weight infants. Thus, repeat glucose measurements in symmetric macrosomic infants are not justified.

In this Meta-analysis, we aimed to quantify the incidence of complications of different methods of bariatric surgery on diabetic patients. Type 2 Diabetes mellitus (T2DM) is increasing worldwide specifically in obese cases. Additionally, obesity worsens T2DM. Complications of each bariatric surgery method were assessed separately; but, meta-analysis of these complications and comparison between procedures in T2DM patients has not been investigated previously. The result of this study will help surgeons to choose the most appropriate surgical technique, considering individual conditions for a diabetic patient. We searched PubMed, Scopus, and ISI for original papers including bariatric surgical procedures for diabetic population and the reported consequences. Data analyses were done using Stata software. Mortality percentage between diabetic and non-diabetic patients was statistically non-significant (P = 0.987). Early and late complications were higher in diabetic group in comparison with non-diabetic (6.0% vs. 1.8%, P = 0.024 and 0.6% vs. 0.3%, P = 0.04, respectively). Most prevalent findings in malabsorptive (7.8%, P < 0.001) and restrictive procedures (80%, P < 0.001) were major complications and hypoglycemic episodes, respectively. As our study showed, most of the complications are not necessarily higher in diabetic population but dependent on the method of surgery.

Japan Congenital Cardiovascluar Surgical Database (JCCVSD) is a nationwide registry whose data are used for health quality assessment and clinical research in Japan. We evaluated the completeness of case registration and the accuracy of recorded data components including postprocedural mortality and complications in the database via on-site data adjudication. We validated the records from JCCVSD 2010 to 2012 containing congenital cardiovascular surgery data performed in 111 facilities throughout Japan. We randomly chose nine facilities for site visit by the auditor team and conducted on-site data adjudication. We assessed whether the records in JCCVSD matched the data in the source materials. We identified 1,928 cases of eligible surgeries performed at the facilities, of which 1,910 were registered (99.1% completeness), with 6 cases of duplication and 1 inappropriate case registration. Data components including gender, age, and surgery time (hours) were highly accurate with 98% to 100% concordance. Mortality at discharge and at 30 and 90 postoperative days was 100% accurate. Among the five complications studied, reoperation was the most frequently observed, with 16 and 21 cases recorded in the database and source materials, respectively, having a sensitivity of 0.67 and a specificity of 0.99. Validation of JCCVSD database showed high registration completeness and high accuracy especially in the categorical data components. Adjudicated mortality was 100% accurate. While limited in numbers, the recorded cases of postoperative complications all had high specificities but had lower sensitivity (0.67-1.00). Continued activities for data quality improvement and assessment are necessary for optimizing the utility of these registries.

Introduction This study aimed to investigate the influence of obesity on pregnancy complications and neonatal outcomes in diabetic and nondiabetic women. Materials and Methods This retrospective case control study was conducted on 1193 pregnant women and their neonates at a tertiary level maternity hospital between March 2007 and 2011. The pregnant women were classified into 2 groups according to the presence of diabetes mellitus. Six hundred and seven patients with gestational diabetes or pregestational diabetes formed the diabetic group (study group) and 586 patients were in the nondiabetic group (control group). Demographic characteristics, body mass index, gestational weight gain, obstetric history, smoking status, type of delivery, gestational ages, pregnancy complications, neonatal outcomes were recorded for each patient. Multivariable logistic regression analysis was performed to evaluate the effect of obesity and diabetes on the pregnancy complications and neonatal outcomes. Results The mean age and pre-pregnancy body mass indices of women with diabetes mellitus were significantly higher than the control groupʼs (p < 0.001). Gestational weight gain and number of smokers were similar among the groups. Multiparity and obesity were more prevalent in the diabetic group compared to controls (both p < 0.001). Although gestational age at birth was earlier in the diabetic group, birth weights were higher in this group than in the control group (both p < 0.001). Cesarean delivery rates, the incidence of macrosomia, and neonatal intensive care unit admission rates were significantly higher in the diabetes group both with normal and increased body mass index (all p < 0.001). However, adverse pregnancy outcomes were comparable between the groups (p = 0.279). Multivariable logistic regression analysis showed that obesity is a significant risk factor for pregnancy complications (OR = 1.772 [95% CI, 1.283 – 2.449], p = 0.001) but not for

A nonenzymatic reaction between reducing sugars and amino groups of proteins, lipids and nucleic acids contributes to the aging of macromolecules and subsequently alters their structural integrity and function. This process has been known to progress at an accelerated rate under hyperglycemic and/or oxidative stress conditions. Over a course of days to weeks, early glycation products undergo further reactions such as rearrangements and dehydration to become irreversibly cross-linked, fluorescent and senescent macroprotein derivatives termed advanced glycation end products (AGEs). There is a growing body of evidence indicating that interaction of AGEs with their receptor (RAGE) elicits oxidative stress generation and as a result evokes proliferative, inflammatory, thrombotic and fibrotic reactions in a variety of cells. This evidence supports AGEs' involvement in diabetes- and aging-associated disorders such as diabetic vascular complications, cancer, Alzheimer's disease and osteoporosis. Therefore, inhibition of AGE formation could be a novel molecular target for organ protection in diabetes. This report summarizes the pathophysiological role of AGEs in vascular complications in diabetes and discusses the potential clinical utility of measurement of serum levels of AGEs for evaluating organ damage in diabetes.

Mental health issues decrease diabetes-specific quality of life independent of glycaemic control and complications: findings from Australia’s living with diabetes cohort study

Background While factors associated with health-related quality of life for people with chronic diseases including diabetes are well researched, far fewer studies have investigated measures of disease-specific quality of life. The purpose of this study is to assess the impact of complications and comorbidities on diabetes-specific quality of life in a large population-based cohort of type 2 diabetic patients. Methods The Living with Diabetes Study recruited participants from the National Diabetes Services Scheme in Australia. Data were collected via a mailed self-report questionnaire. Diabetes-specific quality of life was measured using the Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire. The analyses are for 3609 patients with type 2 diabetes. Regression models with adjustment for control variables investigated the association of complications and comorbidities with diabetes-specific quality of life. Next, the most parsimonious model for diabetes-specific quality of life after controlling for important covariates was examined. Results The expected associations with better diabetes-specific quality of life were evident, such as increased income, not on insulin, better glycaemic control and older age. However, being single and having been diagnosed with cancer were also associated with better ADDQoL. Additionally, poorer diabetes-specific quality of life was strongly sensitive to the presence of diabetes complications and mental health conditions such as depression, anxiety and schizophrenia. These relationships persisted after adjustment for gender, age, duration of diabetes, treatment regimen, sampling region and other treatment and socio-demographic variables. Conclusions A greater appreciation of the complexities of diabetes-specific quality of life can help tailor disease management and self-care messages given to patients. Attention to mental health issues may be as important as focusing on glycaemic control and complications. Therefore

Diabetic ketoacidosis has been described in the literature as a rare possible initial presentation of acromegaly before a diagnosis of acromegaly is eventually made. Indeed, diabetic ketoacidosis is a recognised complication of acromegaly. There are a number of factors that can predispose patients with acromegaly to diabetes as well as to diabetic ketoacidosis. These include high levels of growth hormone and insulin-like growth factor 1 in acromegaly and the effect on glycaemia by medications used in the management of acromegaly. Ketoacidosis has been described in patients with acromegaly even without the presence of an underlying autoimmune diabetes. Patients with acromegaly and ketoacidosis often respond to treatment and may not require long-term insulin. Copyright © 2017. Published by Elsevier B.V.

With the recent widespread use of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), there have been occasional reports on complications associated with its use. Previous reviews on EBUS-TBNA have been limited to studies by skilled operators, thus the results may not always be applicable to recent clinical practice. To assess the safety of EBUS-TBNA for the staging and diagnosis of lung cancer in Japan, a nationwide survey on its current usage status and complications associated with its use was conducted by the Japan Society for Respiratory Endoscopy (JSRE). A questionnaire about EBUS-TBNA performed between January 2011 and June 2012 was mailed to 520 JSRE-accredited facilities. Responses were obtained from 455 facilities (87.5%). During the study period, EBUS-TBNA was performed in 7,345 cases in 210 facilities (46.2%) using a convex probe ultrasound bronchoscope, for 6,836 mediastinal and hilar lesions and 275 lung parenchymal lesions. Ninety complications occurred in 32 facilities. The complication rate was 1.23% (95% confidence interval, 0.97%-1.48%), with hemorrhage being the most frequent complication (50 cases, 0.68%). Infectious complications developed in 14 cases (0.19%) (Mediastinitis, 7; pneumonia, 4; pericarditis, 1; cyst infection, 1; and sepsis, 1). Pneumothorax developed in 2 cases (0.03%), one of which required tube drainage. Regarding the outcome of the cases with complications, prolonged hospitalization was observed in 14 cases, life-threatening conditions in 4, and death in 1 (severe cerebral infarction) (mortality rate, 0.01%). Breakage of the ultrasound bronchoscope occurred in 98 cases (1.33%) in 67 facilities (31.9%), and that of the puncture needle in 15 cases (0.20%) in 8 facilities (3.8%). Although the complication rate associated with EBUS-TBNA was found to be low, severe complications, including infectious complications, were observed, and the incidence of device breakage was high. Since the use of EBUS-TBNA is

Objective. To observe the clinical prophylactic and therapeutic efficacy of Liuwei Dihuang Pills and Ginkgo Leaf Tablets for type 2 diabetic vascular complications. Methods. It was a randomized, double-blind and placebo-controlled clinical trial. 140 outpatients with type 2 diabetes were recruited and randomly divided into the treatment group and control group. The two groups were given basic therapy (management of blood sugar, blood pressure, etc.). Additionally, the treatment group was given Liuwei Dihuang Pills and Ginkgo Leaf Tablets, while the control group was given Liuwei Dihuang Pills and Ginkgo Leaf Tablets placebos. All subjects were followed up for consecutive 36 months and observed monthly. The clinical data as urinary microalbumin to urinary creatinine ratio (Umalb/cr), carotid intima-media thickness (IMT), diabetic nephropathy (DN) and diabetic retinopathy (DR) prevalence, cardiovascular and cerebrovascular events, blood glucose, and blood pressure were collected and analyzed statistically. Results. After 36-month treatment, the Umalb/cr level and DN and DR prevalence in treatment group were all significantly lower than control group ( P < 0.05). However, the IMT level and the incidence of cardiovascular and cerebrovascular events were not significantly different between the two groups ( P > 0.05). Conclusions. Liuwei Dihuang Pills and Ginkgo Leaf Tablets are beneficial to diabetic microvascular complications, while the efficacy to diabetic macrovascular complications needs more observations.

Reduced deformability of red blood cells (RBCs) may play an important role on the pathogenesis of chronic vascular complications of diabetes mellitus. However, available techniques for measuring RBC deformability often require washing process after each measurement, which is not optimal for day-to-day clinical use at point of care. The objectives of the present study are to develop a device and to delineate the correlation of impaired RBC deformability with diabetic nephropathy. We developed a disposable ektacytometry to measure RBC deformability, which adopted a laser diffraction technique and slit rheometry. The essential features of this design are its simplicity (ease of operation and no moving parts) and a disposable element which is in contact with the blood sample. We studied adult diabetic patients divided into three groups according to diabetic complications. Group I comprised 57 diabetic patients with normal renal function. Group II comprised 26 diabetic patients with chronic renal failure (CRF). Group III consisted of 30 diabetic subjects with end-stage renal disease (ESRD) on hemodialysis. According to the renal function for the diabetic groups, matched non-diabetic groups were served as control. We found substantially impaired red blood cell deformability in those with normal renal function (group I) compared to non-diabetic control (P = 0.0005). As renal function decreases, an increased impairment in RBC deformability was found. Diabetic patients with chronic renal failure (group II) when compared to non-diabetic controls (CRF) had an apparently greater impairment in RBC deformability (P = 0.07). The non-diabetic cohort (CRF), on the other hand, manifested significant impairment in red blood cell deformability compared to healthy control (P = 0.0001). The newly developed slit ektacytometer can measure the RBC deformability with ease and accuracy. In addition, progressive impairment in cell deformability is associated with renal function loss in all

Advances in understanding diabetes mellitus (DM) through basic and clinical research have helped clarify and reunify a disease state fragmented into numerous etiologies and subtypes. It is now understood that a common pathophysiology drives the diabetic state throughout its natural history and across its varied clinical presentations, a pathophysiology involving metabolic insults, oxidative damage, and vicious cycles that aggravate and intensify organ dysfunction and damage. This new understanding of the disease requires that we revisit existing diagnostics and treatment approaches, which were built upon outmoded assumptions. 'The Common Pathophysiologic Origins of Diabetes Mellitus and its Complications Construct' is presented as a more accurate, foundational, and translatable construct of DM that helps make sense of the hitherto ambiguous findings of long-term outcome studies.

-meal hyperglycemia of Type 2 diabetes. Epalrestat (Ono Yakuhin Co., 1992) is effective for diabetic neuropathy by reducing the formation of sorbitol. These anti-DM drugs were recently studied and developed in Japan. 4) The Japan Diabetes Society proposed a guideline on diagnostic criteria and treatment of diabetes mellitus (DM) in 1999 and revised it in 2002. DM is classified as insulin-dependent DM (Type l) and non-insulin dependent DM (Type 2). Type 1, juvenile onset DM, requires insulin therapy to prevent ketosis and to sustain life. Treatment of type 2, adult onset DM, is recommended as a step-by-step method, starting with dietary-exercise therapy, followed by oral hypoglycemic drugs and then insulin therapy. DM patients with complications should have a therapy devised to match their circumstances. 5) Epidemiological aspects: The mortality rate of DM compared to the time of drug appearance was traced from 1920 to 2000. The curve goes down slowly in the time frame of World War II, but rises from 1950 to 1970. The elevation could not be suppressed by the appearance of SUs, BGs or improved insulin preparations. The curve runs flat from 1980 to 1990, which might be related to the use of purified insulin or human insulin therapy. The mortality rate of DM indicates that death by hyperglycemic coma and other deaths resulting from complications are excluded. The survey of the principal cause of death by DM during the period of 1981-1990 indicates that the death rate due to hyperglycemic coma is only 1.7% of the total deaths caused by DM. The effect of drug therapy on all of the death resulting from DM is not detected. Hospital visitation and admission rates of the DM patients have been recorded since 1952 in Japan. This curve is rising continuously, and none of the antidiabetic drugs has been able to suppress it. These data show that the antidiabetic drugs relieve DM symptoms through their effective hypoglycemic actions, but that they cannot suppress the mortality rate of DM. It is

Scope Recently, many publicly funded healthcare organizations suffered from an economical crisis. This forced some organizations to utilize less costly alternatives where possible. Insulin cartridges and vials are examples. Many patients are questioning the difference between the two alternatives as they contain the same active ingredient. Objective To find out if insulin cartridges really provide a lower risk of potential diabetes complications than traditional vials. Method A questionnaire was used to ask two random samples of diabetic patients about the development of some diabetes complications. The first sample (n = 41) consisted of patients using cartridges; the second sample (n = 40) consisted of patients using vials. Patients were randomly selected from the endocrine clinic and the out-patient pharmacy in Al-Hussein Hospital in King Hussein Medical Center in Amman- Jordan. Results 44% of respondents in the first sample did not suffer from any complication; on the other hand, the percentage was only 15% of respondents in the second sample. All respondents (100%) in the first sample suffered from only 2 complications or less; however, 25% of the respondents in the second sample suffered from 3 or more complications. Nephropathy complications, were slightly higher in the first sample; 22% compared to 15% in the second sample. On the other hand, all complications reported in the second sample were higher; 30% for neuropathy, 65% for retinopathy complications and 42.5% for extremities damage compared to only 9.7%, 7.3% and 26.8% respectively in the first sample. Conclusion In general, respondents who were using cartridges reported a lesser incidence of diabetes complications. Although many organizations suffered from an economical crisis, the cost-effectiveness aspect should be taken into consideration when purchasing medical alternatives. This will provide higher quality of life for patients and eventually lower hidden and future costs for the organizations

Performance of people with diabetes in the labor market: An empirical approach controlling for complications.

This paper introduces a framework for modelling the impact that diabetes has on employment status and wages, improving the existing literature by controlling for diabetes-related complications. Using the last wave of the Spanish National Health Survey, we find that 1710 adults out of the original sample of 36,087 have diabetes, reporting higher rates of unemployment. Our empirical results suggest that persons with diabetes, compared with non-diabetic persons, have poorer labor outcomes in terms of length of unemployment and lower income. However, diabetes is not significantly associated with unemployment probabilities, suggesting that the burden of diabetes on employment is mediated by lifestyle factors and clinical and functional complications. In addition, there are mixed outcomes to this econometric approach, depending on age and gender, among other factors. This interesting finding has several implications for research and policy on strategies to get lower health inequalities. Copyright © 2017 Elsevier B.V. All rights reserved.

Nerve decompression and neuropathy complications in diabetes: Are attitudes discordant with evidence?

Nickerson, D. Scott

2017-01-01

ABSTRACT External neurolysis of the nerve at fibro-osseous tunnels has been proprosed to treat or prevent signs, symptoms, and complications in the lower extremity of diabetes patients with sensorimotor polyneuropathy. Nerve decompression is justified in the presence of symptomatic compressed nerves in the several fibro-osseous tunnels of the extremities, which are known to be frequent in diabetes. Quite a body of literature has accumulated reporting results after such nerve decompression in the leg, describing pain relief and sensibility improvement, as well as balance recovery, diabetic foot ulcer prevention, curtailed ulcer recurrence risk, and amputation avoidance. Historical academic hesitance to endorse surgical treatments for pain and numbness in diabetes was based primarily on the early retrospective reports’ potential for bias and placebo effects, and that the hypothetical basis for surgery lies outside the traditional etiology paradigm of length-dependent axonopathy. This reticence is here critiqued in view of recent studies using objective, measured outcome protocols which nullify such potential confounders. Pain relief is now confirmed with Level 1 studies, and Level 2 prospective information suggests protection from initial diabetic foot ulceration and most neuropathic ulcer recurrences. In view of the potential for nerve decompression to be useful in addressing some of the more difficult, expensive, and life altering complications of diabetic neuropathy, this secondary compression thesis and operative treatment methodology may deserve reassessment.

A balanced diet is crucial for healthy development and prevention of musculoskeletal related diseases. Diets high in fat content are known to cause obesity, diabetes and a number of other disease states. Our group and others have previously reported that activity of the urea cycle enzyme arginase is involved in diabetes-induced dysregulation of vascular function due to decreases in nitric oxide formation. We hypothesized that diabetes may also elevate arginase activity in bone and bone marrow, which could lead to bone-related complications. To test this we determined the effects of diabetes on expression and activity of arginase, in bone and bone marrow stromal cells (BMSCs). We demonstrated that arginase 1 is abundantly present in the bone and BMSCs. We also demonstrated that arginase activity and expression in bone and bone marrow is up-regulated in models of diabetes induced by HFHS diet and streptozotocin (STZ). HFHS diet down-regulated expression of healthy bone metabolism markers (BMP2, COL-1, ALP, and RUNX2) and reduced bone mineral density, bone volume and trabecular thickness. However, treatment with an arginase inhibitor (ABH) prevented these bone-related complications of diabetes. In-vitro study of BMSCs showed that high glucose treatment increased arginase activity and decreased nitric oxide production. These effects were reversed by treatment with an arginase inhibitor (ABH). Our study provides evidence that deregulation of L-arginine metabolism plays a vital role in HFHS diet-induced diabetic complications and that these complications can be prevented by treatment with arginase inhibitors. The modulation of L-arginine metabolism in disease could offer a novel therapeutic approach for osteoporosis and other musculoskeletal related diseases. PMID:26704078

Despite being featured as metabolic disorder, diabetic patients are largely affected by hyperglycemia-induced vascular abnormality. Accumulated evidence has confirmed the beneficial effect of endothelial progenitor cells (EPCs) in coronary heart disease. However, antivascular endothelial growth factor (anti-VEGF) treatment is the main therapy for diabetic retinopathy and nephropathy, indicating the uncertain role of EPCs in the pathogenesis of diabetic microvascular disease. In this review, we first illustrate how hyperglycemia induces metabolic and epigenetic changes in EPCs, which exerts deleterious impact on their number and function. We then discuss how abnormal angiogenesis develops in eyes and kidneys under diabetes condition, focusing on "VEGF uncoupling with nitric oxide" and "competitive angiopoietin 1/angiopoietin 2" mechanisms that are shared in both organs. Next, we dissect the nature of EPCs in diabetic microvascular complications. After we overview the current EPCs-related strategies, we point out new EPCs-associated options for future exploration. Ultimately, we hope that this review would uncover the mysterious nature of EPCs in diabetic microvascular disease for therapeutics.

Diabetic complications including diabetic nephropathy, retinopathy, and neuropathy are as major causes of morbidity and mortality in diabetes individuals worldwide and current therapies are still unsatisfactory. One of the reasons for failure to develop effective treatment is the lack of fundamental understanding for underlying mechanisms. Genetic studies are powerful tools to dissect disease mechanism. The heritability (h2) was estimated to be 0.3-0.44 for diabetic nephropathy and 0.25-0.50 for diabetic retinopathy respectively. Previous linkage studies for diabetic nephropathy have identified overlapped linkage regions in 1q43-44, 3q21-23, 3q26, 10p12-15, 18q22-23, 19q13, 22q11-12.3 in multiple ethnic groups. Genome-wide association studies (GWAS) of diabetic nephropathy have been conducted in several populations. However, most of the identified risk loci could not be replicated by independent studies with a few exceptions including those in ELMO1, FRMD3, CARS, MYO16/IRS2, and APOL3-MYH9 genes. Functional studies of these genes revealed the involvement of cytoskeleton reorganization (especially non-muscle type myosin), phagocytosis of apoptotic cells, fibroblast migration, insulin signaling, and epithelial clonal expansion in the pathogenesis of diabetic nephropathy. Linkage analyses of diabetic retinopathy overlapped only in 1q36 region and current results from GWAS for diabetic retinopathy are inconsistent. Conclusive results from genetic studies for diabetic neuropathy are lacking. For now, small sample sizes, confounding by population stratification, different phenotype definitions between studies, ethnic-specific associations, the influence of environmental factors, and the possible contribution of rare variants may explain the inconsistencies between studies.

The number of individuals with prediabetes is expected to grow substantially and estimated to globally affect 482 million people by 2040. Therefore, effective methods for diagnosing prediabetes will be required to reduce the risk of progressing to diabetes and its complications. The current biomarkers, glycated hemoglobin (HbA1c), fructosamine, and glycated albumin have limitations including moderate sensitivity and specificity and are inaccurate in certain clinical conditions. Therefore, identification of additional biomarkers is being explored recognizing that any single biomarker will also likely have inherent limitations. Therefore, combining several biomarkers may more precisely identify those at high risk for developing prediabetes and subsequent progression to diabetes. This review describes recently identified biomarkers and their potential utility for addressing the burgeoning epidemic of dysglycemic disorders. PMID:28860833

Many non-European ethnic groups have an increased risk for diabetes; however, the published literature demonstrates considerable uncertainty about the rates of diabetes complications among minority populations. The objective of this study was to determine the risks of cardiovascular complications and of mortality after diabetes diagnosis for South Asian and Chinese patients, compared with European patients. A population-based cohort study identified all 491,243 adults with newly diagnosed diabetes in Ontario, Canada, between April 2002 and March 2009. Subjects were followed until March 2011 for the first occurrence of any cardiovascular complication of diabetes (coronary artery disease, stroke, or lower-extremity amputation) and for all-cause mortality. Median follow-up was 4.7 years. The crude incidence of cardiovascular complications after diabetes diagnosis was 17.9 per 1,000 patient-years among European patients, 12.0 among South Asian patients, and 7.7 among Chinese patients. After adjusting for baseline characteristics, the cause-specific hazard ratios (HRs) for cardiovascular complications relative to European patients were 0.95 (95% CI 0.90-1.00; P = 0.056) and 0.50 (0.46-0.53; P < 0.001) for South Asian and Chinese patients, respectively. Mortality was lower for both minority groups (adjusted HR for South Asian patients 0.56 [95% CI 0.52-0.60]; P < 0.001; for Chinese patients 0.58 [0.55-0.62]; P < 0.001). Chinese patients were at substantially lower risk than European patients for cardiovascular complications after diabetes diagnosis, whereas South Asian patients were at comparable risk. Mortality after diabetes diagnosis was markedly lower for both minority populations.

This study estimates health utilities (HU) in Sweden for a range of type 2 diabetes-related complications using EQ-5D and two alternative tariffs (UK and Swedish) from 1757 patients with type 2 diabetes from the Swedish National Diabetes Register (NDR). Ordinary least squares were used for statistical analysis. Lower HU was found for female gender, younger age at diagnosis, higher BMI, and history of complications. Microvascular and macrovascular complications had the most negative effect on HU among women and men, respectively. The greatest decline in HU was associated with kidney disorders (−0.114) using the UK tariff and stroke (−0.059) using the Swedish tariff. Multiple stroke and non-acute ischaemic heart disease had higher negative effect than a single event. With the UK tariff, each year elapsed since the last microvascular/macrovascular complication was associated with 0.013 and 0.007 units higher HU, respectively. We found important heterogeneities in effects of complications on HU in terms of gender, multiple event, and time. The Swedish tariff gave smaller estimates and so may result in less cost-effective interventions than the UK tariff. These results suggest that incorporating subgroup-specific HU in cost-utility analyses might provide more insight for informed decision-making. PMID:24810579

Type 1 diabetes mellitus (T1DM) is a major disease affecting a large number of young patients. In the recent years, retinal vascular imaging has provided an objective assessment of vascular health in patients with T1DM. Our study aimed to review the current literature on retinal vascular parameters in young patients with T1DM in order to understand the following: (i) How retinal vessels are affected in T1DM (ii) How such vascular changes can be predictive of future diabetic microvascular complications METHODS: We performed a systematic review and extracted relevant data from 17 articles. We found significant correlations between retinal vessel changes and diabetes-related risk factors (eg, hypertension, hyperlipidemia, and obesity), diabetes-related features (eg, diabetes duration and glycemic control), and diabetes-related microvascular complications (eg, diabetic retinopathy, nephropathy, and neuropathy). Our findings suggest that retinal microvasculature is associated with both disease severity and complications in young patients with T1DM. © 2016 John Wiley & Sons Ltd.

Postprandial and basal hyperglycaemia in type 2 diabetes: Contributions to overall glucose exposure and diabetic complications.

PubMed

Monnier, L; Colette, C

2015-12-01

Both postprandial and fasting (basal) hyperglycaemia contribute to overall hyperglycaemia (ambient hyperglycaemia) in type 2 diabetes (T2D). Postprandial glucose is the main contributor in fairly well controlled individuals, whereas basal hyperglycaemia becomes the preponderant contributor in poorly controlled patients. A more generally acceptable description of the contribution of postprandial glucose is to simply say that the absolute impact of postprandial glucose to HbA1c remains constant at approximately 1% across the entire HbA1c spectrum of non-insulin-treated patients with T2D. While epidemiological and pathophysiological studies seem to indicate that excessive postprandial glucose excursions play a role in or are predictors of cardiovascular diseases, there is still currently a lack of clinical evidence that correcting post-meal hyperglycaemia can improve clinical outcomes. However, even in the absence of consensus, there are many reasons for thinking that excessive postprandial glucose might be an independent risk factor for diabetic complications as it contributes to both overall glucose exposure and glycaemic variability, especially in those who have HbA1c levels < 7.5-8%. Given that excessive glucose fluctuations from peaks to nadirs activate oxidative stress, it seems reasonable to consider that a key player in the pathogenesis of diabetic complications, according to the latest IDF guidelines, is post-meal glucose, thereby warranting its assessment and treatment when found at abnormally elevated levels. Nevertheless, healthcare professionals should bear in mind that targeting both post-meal and basal plasma glucose, giving equal consideration to both of them, is probably the best strategy for achieving optimal glycaemic control and thus preventing or reducing the risk of diabetic complications.

Type 2 diabetes (T2D) in young adults is associated with a high risk of diabetes complications. To investigated the demography and the emergence of complications of young adults with T2D in the central Auckland region where there has been substantial immigration. In total, 310 young adults with T2D (<40 years) were registered with the Auckland Diabetes Centre in 2015. We documented demographic, anthropometric and metabolic variables and prevalence and the emergence of complications. Three demographic groups accounted for 243 participants (78%): 135 (44%) were migrants of Asian or Pacific Island origin, diagnosed a median 9 years after migration at a mean age of 28 ± 6 years; 88 (29%) were New Zealand-born Pāsifika descent, with a high prevalence of morbid obesity and 37 (12%) had major mental illness or intellectual disability. At diagnosis, the median HbA1c was 80 mmol/mol, and in 28%, it was ≥100 mmol/mol. A median 6 years after diagnosis, 56% had some degree of retinopathy, with the prevalence related both to the duration of diabetes and glycaemic control (P = 0.001). Forty-four percent of subjects had abnormal albuminuria at diagnosis (12% with macroalbuminuria). Increased albuminuria was strongly associated with obesity (P = 0.002). The development of CKD stages 4-5 was related both to the severity of retinopathy and degree of albuminuria at diagnosis (P = 0.0001). Major cardiovascular events were related to the severity of retinopathy at diagnosis (P = 0.0001). New migrants, New Zealand-born Pāsifika and patients with mental illness or an intellectual disability comprise the bulk of young onset T2D. The disease is aggressive, and by the age of 40, patients are already developing advanced complications. © 2017 Royal Australasian College of Physicians.

Women with type 1 diabetes have increased risk of infertility compared to women without diabetes even after adjustment for irregular menses, but aetiologies are incompletely understood. Our aim was to examine the prevalence of abnormalities in ovarian markers consistent with polycystic ovary syndrome in women with type 1 diabetes and associations with irregular menses and diabetes-specific variables. We conducted a secondary analysis of women in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study (DCCT/EDIC), a randomized trial and observational follow-up of intensive insulin therapy for type 1 diabetes. We included women with anti-Müllerian hormone (AMH) measurements among women not using oral contraceptives (n = 187). Initial AMH and testosterone measures were performed between EDIC years 1 and 4. History of irregular menses was assessed annually. The median age of women was 35 (interquartile ratio 29, 40) years; 133 (35%) had elevated AMH and 62 (17%) reported irregular menses. Twelve per cent of women had relative elevations in total testosterone. In multivariable models, lower insulin dosages were associated with higher AMH concentrations (P = .0027), but not diabetes duration, glycemic control, body mass index or irregular menses. Neither irregular menses nor diabetes-specific variables were associated with testosterone concentrations. Among women with type 1 diabetes in their thirties, abnormalities in ovarian markers are common and not associated with irregular menses and thus may partially account for decreased fecundity in women with type 1 diabetes. © 2018 John Wiley & Sons Ltd.

Diabetes self-management education is not associated with a reduction in long-term diabetes complications: an effectiveness study in an elderly population.

The efficacy of diabetes self-management education on glycaemic control, self-care behaviour and knowledge has been established by short-term studies in experimental settings. The objective of this study was to assess its effectiveness to improve quality of care and reduce the risk of long-term diabetes complications in unselected older patients with recently diagnosed diabetes in routine clinical care. Using population-level health care administrative databases and registries, all patients aged ≥66 years in Ontario, Canada with diabetes for <5 years were identified. Self-management education programme attendees (n = 8485) in 2006 were matched with non-attendees using high-dimensional propensity scores, creating extremely well-balanced study arms. Quality of care measures and the long-term risk of diabetes complications were compared. Self-management programme attendees were more likely than non-attendees to achieve process measures of quality of care such as retinal screening examinations (75.3% versus 70.3%, adjusted relative risk 1.05, 99% confidence interval 1.03-1.08), and ≥2 glycated haemoglobin tests (57.5% versus 53.3%, adjusted relative risk 1.08, 99% confidence interval 1.05-1.11). However, with a median follow-up of 5.3 years, diabetes complications and mortality were not different between arms. In real-world clinical care, self-management education for older patients with recently diagnosed diabetes was associated with modest improvements in quality of care, but no reductions in long-term clinical events. © 2015 John Wiley & Sons, Ltd.

Frailty and sarcopenia - newly emerging and high impact complications of diabetes.

PubMed

Sinclair, Alan J; Abdelhafiz, Ahmed H; Rodríguez-Mañas, Leocadio

Diabetes increases the risk of physical dysfunction and disability. Diabetes-related complications and coexisting morbidities partially explain the deterioration in physical function. The decline in muscle mass, strength and function associated with diabetes leads to sarcopenia, frailty and eventually disability. Frailty acts as a mediator in the pathogenesis of disability in older people with diabetes and its measurement in routine daily practice is recommended. Frailty is a dynamic process which progresses from a robust condition to a pre-frail stage then frailty and eventually disability. Therefore, a multimodal intervention which includes adequate nutrition, exercise training, good glycaemic control and the use of appropriate hypoglycemic medications may help delay or prevent the progression to disability.

Advances in diabetes for the millennium: vitamins and oxidant stress in diabetes and its complications.

PubMed

Chertow, Bruce

2004-11-01

Hyperinduced oxidant stress may have a role in the pathogenesis of diabetes and its micro- and macrovascular complications. Attaining euglycemia and the use of antioxidant vitamins could reduce oxidant stress and complications. In general, evidence does not support the use of supplements, and supplements are not recommended unless patients are deficient. Use of vitamins in excess may have adverse effects. Vitamin supplements are indicated in patients deficient in vitamins due to inadequate dietary intake or intestinal disease. Treatment with proper amounts of vitamins and antioxidants is best accomplished with a balanced diet including 3 servings of vegetables and 2 servings of fruits. Regarding supplementation of specific vitamins: carotene cannot be recommended in view of the possible harm and lack of benefit in clinical studies. Vitamin A (retinol) and Vitamin D should be repleted if deficient by laboratory assay. Excesses should be avoided. Vitamin A supplements, particularly in pregnancy, should not exceed 10,000 IU daily or a supplement should not exceed 25,000 units weekly. Vitamin E (alpha-tocopherol) alone in doses of 400 units is of questionable value, and larger doses may cause intracranial hemorrhage or interact negatively with lipid-lowering drugs. Vitamin E should not be used in patients who have bleeding disorders or patients on anticoagulants or acetylsalicylic acid (ASA). Vitamin C (ascorbic acid) losses in urine may be excessive in diabetic patients and may require repletion to 200 mg in nonsmokers and 250 mg in smokers. Further studies are needed testing: (1) vitamin supplementation in subgroups of patients at high risk for specific complications using tissue-specific indicators of oxidative stress; (2) the role of oxidative stress in nephropathy, diabetic myocardiopathy, dermopathy, joint limitation syndromes, peripheral edema, metabolic bone disease, and pregnancy; (3) the impact of renal failure on oxidative stress; and (4) the effects of

Wound Bioburden and Infection-Related Complications in Diabetic Foot Ulcers

Gardner, Sue E.; Frantz, Rita A.

2013-01-01

The identification and diagnosis of diabetic foot ulcer (DFU) infections remains a complex problem. Because inflammatory responses to microbial invasion may be diminished in persons with diabetes, clinical signs of infection are often absent in persons with DFUs when infection is limited to localized tissue. In the absence of these clinical signs, microbial load is believed to be the best indicator of infection. Some researchers, however, believe microbial load to be insignificant and type of organism growing in the ulcer to be most important. Previous studies on the microbiology of DFUs have not provided enough evidence to determine the microbiological parameters of importance. Infection-related complications of DFUs include wound deterioration, osteomyelitis, and amputation. Risk factors for amputation include age, peripheral vascular disease, low transcutaneous oxygen, smoking, and poor glycemic control. These risk factors are best measured directly with physiological measures of arterial perfusion, glycemic control, sensory neuropathy, plantar pressures, and activity level and by controlling off-loading. DFU bioburden has not been examined as a risk factor for infection-related complications. To address the relationship between wound bioburden and the development of infection-related complications in DFUs, tightly controlled prospective studies based on clearly defined, valid measures of wound bioburden and wound outcomes are needed. This article reviews the literature and proposes a model of hypothesized relationships between wound bioburden—including microbial load, microbial diversity, and pathogenicity of organisms—and the development of infection-related complications.

Diabetic complications in the lower extremity are associated with significant morbidity and mortality, and impact heavily upon the public health system. Early and accurate recognition of these abnormalities is crucial, enabling the early initiation of treatments and thus avoiding or minimizing deformity, dysfunction and amputation. Following careful clinical assessment, radiological imaging is central to the diagnostic and follow-up process. We aim to provide a comprehensive review of diabetic lower limb complications designed to assist radiologists and to contribute to better outcomes for these patients. PMID:26111070

Sodium glucose cotransporter 2 (SGLT2) inhibitors have been available for the treatment of type 2 diabetes (T2DM) in Japan since April 2014. The prescription rate in Japan is low in comparison to Western countries. We summarize the results obtained from the phase 3 clinical trials and clinical studies involving Japanese T2DM patients. We also discuss the current situation and the future prospects of SGLT2 inhibitors in Japan. Unexpected adverse events, such as cerebral infarction and diabetic ketoacidosis have been reported from clinics shortly after the initiation of SGLT2 inhibitor treatment. However, the reductions in blood glucose levels and body weight have been demonstrated in phase 3 trials using 6 types of SGLT2 inhibitors, while observational studies of Japanese T2DM patients, which were performed in the clinical setting, showed that the incidence of adverse drug reactions, such as severe hypoglycemia, was low. SGLT2 inhibitors are also considered to be effective for treating Japanese patients with T2DM. When prescribing SGLT2 inhibitors, it is necessary to ensure that they are used appropriately because the Japanese T2DM patient population has a high proportion of elderly individuals and a high incidence of cerebrovascular disease.

Diabetes in Algeria and challenges for health policy: a literature review of prevalence, cost, management and outcomes of diabetes and its complications

PubMed Central

2014-01-01

Background Diabetes has become an increasingly prevalent and severe public health issue in Algeria. This article investigates the prevalence, the cost and the management of this disease. Its first objective is to better understand the burden (both from an epidemiological and economic perspective) and management of diabetes. The second objective is to understand the health policy strategy adopted by Algeria in order to respond to the disease. Methods We conducted a literature review of prevalence, costs, management and outcomes of diabetes and its complications. This was complemented by data compilations and results of expert consultations. Results The epidemiology of diabetes is continually evolving and is becoming more problematic. The national evidence suggests that the prevalence of diabetes in Algeria has increased from 6.8% in 1990 to 12.29% in 2005, but is quite higher among certain groups and areas of the country. This disease affects all population groups, especially 35–70 year olds, who constitute a large segment of the working population. There are very few estimates of the cost of diabetes. These include a 1998 study on the total cost of type 1 diabetes (USD 11.6 million, which, inflated to 2013 value, totals to USD 16.6 million), a study on the cost of complications in 2010 (at 2013 value, ranging from USD 141 for first-year treatment of peripheral vascular disease to USD 30,441 for first-year cost of renal transplantation) and the 2013 IDF estimates of total cost of type 1 and type 2 diabetes (USD 513 million). Conclusions As the prevalence of diabetes continues to increase, the financial burden will increasingly weigh heavily on social security resources and the government budget. Future priorities must focus on empowering general practitioners in treating type 2 diabetes, improving screening of diabetes and its complications, tackling the growing obesity epidemic, strengthening health information systems and implementing the national diabetes

Metabolic memory and chronic diabetes complications: potential role for epigenetic mechanisms.

PubMed

Intine, Robert V; Sarras, Michael P

2012-10-01

Recent estimates indicate that diabetes mellitus currently affects more than 10 % of the world's population. Evidence from both the laboratory and large scale clinical trials has revealed that prolonged hyperglycemia induces chronic complications which persist and progress unimpeded even when glycemic control is pharmaceutically achieved via the phenomenon of metabolic memory. The epigenome is comprised of all chromatin modifications including post translational histone modification, expression control via miRNAs and the methylation of cytosine within DNA. Modifications of these epigenetic marks not only allow cells and organisms to quickly respond to changing environmental stimuli but also confer the ability of the cell to "memorize" these encounters. As such, these processes have gained much attention as potential molecular mechanisms underlying metabolic memory and chronic diabetic complications. Here we present a review of the very recent literature published pertaining to this subject.

Acute Pancreatitis Complicated with Diabetic Ketoacidosis in a Young Adult without Hypertriglyceridemia: A Case Report.

Kim, Jung Hyun; Oh, Myung Jin

2016-11-25

Systemic complications related to acute pancreatitis include acute respiratory distress syndrome, multiple organ dysfunction syndrome, disseminated intravascular coagulation, hypocalcemia, hyperglycemia, and insulin dependent diabetes or diabetic ketoacidosis. In practice, the development of diabetic ketoacidosis induced by acute pancreatitis is rare and generally associated with hypertriglyceridemia. However, herein we report a case of a 34-year-old female without hypertriglyceridemia, who was diagnosed with acute pancreatitis complicated with diabetic ketoacidosis. The patient was admitted with complaints of febrile sensation, back pain, and abdominal pain around the epigastric area. Levels of serum amylase and lipase were elevated to 663 U/L and 3,232 U/L. Contrast-enhanced abdominal CT showed pancreatic swelling, peri-pancreatic fat infiltration and fluid collection. The patient was initially diagnosed with simple acute pancreatitis. Though the symptoms were rapidly relieved after initiation of treatment, severe hyperglycemia (575 mg/dL), severe metabolic acidosis (pH 6.9), and ketonuria developed at four days after hospitalization. However, serum triglyceride levels remained within the normal range (134 mg/dL). Finally, the patient was diagnosed with acute pancreatitis complicated with diabetic ketoacidosis unrelated to hypertriglyceridemia. She recovered through insulin and fluid therapy, and receives insulin therapy at the outpatient clinic.

Effects of Silymarin on Diabetes Mellitus Complications: A Review.

Diabetes mellitus is a common metabolic disorder that is caused by a deficit in the production of (type 1) or response to (type 2) insulin. Diabetes mellitus is characterized by a state of chronic hyperglycemia and such symptoms as weight loss, thirst, polyuria, and blurred vision. These disturbances represent one of the major causes of morbidity and mortality nowadays, despite available treatments, such as insulin, insulin secretagogues, insulin sensitizers, and oral hypoglycemic agents. However, many efforts have been made to discover new drugs for diabetes treatment, including medicinal plant extracts. Silymarin is a powder extract of the seeds from Silybum marianum, a plant from the Asteraceae family. The major active ingredients include four isomers: silybin, isosilybin, silychristin, and silydianin. Silymarin is indicated for the treatment of hepatic disorders, such as cirrhosis, chronic hepatitis, and gallstones. Moreover, several studies of other pathologies, including diabetes, sepsis, osteoporosis, arthritis, hypercholesterolemia, cancer, viral infections, and Alzheimer's and Parkinson's diseases, have tested the effects of silymarin and reported promising results. This article reviews data from clinical, in vivo, and in vitro studies on the use of silymarin, with a focus on the complications of diabetes, including nephropathy, neuropathy, healing delays, oxidative stress, hepatotoxicity, and cardiomyopathy.

Saving the limb in diabetic patients with ischemic foot lesions complicated by acute infection.

PubMed

Clerici, Giacomo; Faglia, Ezio

2014-12-01

Ischemia and infection are the most important factors affecting the prognosis of foot ulcerations in diabetic patients. To improve the outcome of these patients, it is necessary to aggressively treat 2 important pathologies--namely, occlusive arterial disease affecting the tibial and femoral arteries and infection of the ischemic diabetic foot. Each of these 2 conditions may lead to major limb amputation, and the presence of both critical limb ischemia (CLI) and acute deep infection is a major risk factor for lower-extremity amputation. Thus, the management of diabetic foot ulcers requires specific therapeutic approaches that vary significantly depending on whether foot lesions are complicated by infection and/or ischemia. A multidisciplinary team approach is the key to successful treatment of a diabetic foot ulcer: ischemic diabetic foot ulcers complicated by acute deep infection pose serious treatment challenges because high levels of skill, organization, accuracy, and timing of intervention are required to maximize the chances of limb salvage: these complex issues are better managed by a multidisciplinary clinical group. © The Author(s) 2014.

It has been hypothesized that insulin resistance may be involved in the development of type 1 diabetes complications and early diagnosis would be important for their prevention. Our aim was to study insulin resistance in our population of children with type 1 diabetes and to identify associated early risk factors for micro- and macrovascular complications. A descriptive, cross-sectional study was conducted including 150 children with type 1 diabetes. Anthropometric, bioelectric impedance, carotid Doppler ultrasonography, electromyography, and conduction velocity studies were performed. Baseline plasma glucose, lipid profile, uric acid, plasma thyrotropin, glycosylated hemoglobin A1C, and microalbuminuria were assessed. More insulin-resistant patients were defined as those having an estimated glucose disposal rate (eGDR) value below the first quartile. Clinically manifest microvascular complications were not found in any of the patients. More insulin-resistant patients had a greater sub scapular fold thickness, a higher incidence of obesity (12% vs. 1.7% p 0.007), higher fructosamine levels (496 vs. 403 p<0.00019, and a higher incidence of altered lipid metabolism (70% vs. 39% p 0.0007). In the subgroup of patients with lower eGDR there were more children with lipid disorders, obesity, and worse diabetic control, which, if not corrected, may lead to development of micro- and macrovascular complications.

The aim of this study was to investigate the effects of high-advanced glycation end products (AGEs) diet on diabetic vascular complications. The Streptozocin (STZ)-induced diabetic mice were fed with high-AGEs diet. Diabetic characteristics, indicators of renal and cardiovascular functions, and pathohistology of pancreas, heart and renal were evaluated. AGEs/RAGE/ROS pathway parameters were determined. During the experiments, the diabetic mice exhibited typical characteristics including weight loss, polydipsia, polyphagia, polyuria, high-blood glucose, and low-serum insulin levels. However, high-AGEs diet effectively aggravated these diabetic characteristics. It also increased the 24-h urine protein levels, serum levels of urea nitrogen, creatinine, c-reactive protein (CRP), low density lipoprotein (LDL), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in the diabetic mice. High-AGEs diet deteriorated the histology of pancreas, heart, and kidneys, and caused structural alterations of endothelial cells, mesangial cells and podocytes in renal cortex. Eventually, high-AGEs diet contributed to the high-AGE levels in serum and kidneys, high-levels of reactive oxygen species (ROS) and low-levels of superoxide dismutase (SOD) in serum, heart, and kidneys. It also upregulated RAGE mRNA and protein expression in heart and kidneys. Our results showed that high-AGEs diet deteriorated vascular complications in the diabetic mice. The activation of AGEs/RAGE/ROS pathway may be involved in the pathogenesis of vascular complications in diabetes. Copyright © 2016 China Pharmaceutical University. Published by Elsevier B.V.

The world's Indigenous peoples are experiencing an unprecedented epidemic of type 2 diabetes [T2DM] but little has been published describing the complications burden. The objective of this paper was to conduct a systematic review of T2DM complications in Indigenous populations worldwide. A literature review was conducted using PubMed and EMBASE to examine available complications data. Country, Indigenous population, authors, publication year, total sample size, Indigenous sample size, age, methodology, and prevalence of nephropathy, end-stage renal disease, retinopathy, neuropathy, lower extremity amputations, cardiovascular disease, hospitalizations and mortality due to diabetes were recorded. One-hundred and eleven studies were selected. Results revealed a disproportionate burden of disease complications among all Indigenous peoples regardless of their geographic location. Complication rates were seen to vary widely across Indigenous groups. Gaps were found in the published literature on complications among Indigenous populations, especially those living in underdeveloped countries. These gaps may be in part due to the challenges caused by varying operational practices, research methodologies, and definitions of the term Indigenous, making documentation of rates among these peoples problematic. Comprehensive surveillance applying standardized definitions and methodologies is needed to design targeted prevention and disease management strategies for Indigenous peoples with T2DM.

Oxidative Stress in Diabetes: Implications for Vascular and Other Complications

PubMed Central

Pitocco, Dario; Tesauro, Manfredi; Alessandro, Rizzi; Ghirlanda, Giovanni; Cardillo, Carmine

2013-01-01

In recent decades, oxidative stress has become a focus of interest in most biomedical disciplines and many types of clinical research. Increasing evidence shows that oxidative stress is associated with the pathogenesis of diabetes, obesity, cancer, ageing, inflammation, neurodegenerative disorders, hypertension, apoptosis, cardiovascular diseases, and heart failure. Based on these studies, an emerging concept is that oxidative stress is the “final common pathway” through which the risk factors for several diseases exert their deleterious effects. Oxidative stress causes a complex dysregulation of cell metabolism and cell–cell homeostasis; in particular, oxidative stress plays a key role in the pathogenesis of insulin resistance and β-cell dysfunction. These are the two most relevant mechanisms in the pathophysiology of type 2 diabetes and its vascular complications, the leading cause of death in diabetic patients. PMID:24177571

The effectiveness of annual eye examinations in diabetic children is unclear. We sought to determine the prevalence and onset of ocular pathology in children with diabetes mellitus (DM), identify risk factors for ocular disease, and recommend a screening regimen for asymptomatic children. Retrospective, consecutive cohort study. Children aged less than 18 years with type 1 or 2 DM examined over a 4-year period. All children underwent a complete eye examination, including dilated fundoscopy and cycloplegic refraction. A literature review was performed, identifying the youngest reported age and shortest reported duration of DM before the diagnosis of diabetic retinopathy (DR). Prevalence of DR, cataract, high refractive error, and strabismus. A total of 370 children (mean age, 11.2 years; range, 1-17.5 years) had 693 examinations, with a mean DM duration of 5.2 years (range, 0.1-16.2 years) and a mean hemoglobin A1c (HbA1c) of 8.6 (range, 5-≥14). No children had DR. A total of 12 children had cataract; 5 required extraction but were identified by decreased vision, not diabetic screening. A total of 19 children had strabismus; only 1 was microvascular paralytic strabismus. A total of 41 children had high refractive error. There were no associations between these conditions and duration or control of DM. In the literature, the youngest age at diagnosis of severe DR was 15 years, and the shortest duration of disease was 5 years. Diabetic retinopathy is rare in children regardless of duration and control of DM. On the basis of our study and literature review, screening examinations for type 1 diabetes could begin at age 15 years or at 5 years after the diagnosis of DM, whichever occurs later, unless the child is judged by the endocrinologist as being at unusually high risk. Other ocular complications are identifiable through existing amblyopia screening methods. Copyright © 2015 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.

U.S. Complicity and Japan's Wartime Medical Atrocities: Time for a Response.

PubMed

Devolder, Katrien

2015-01-01

Shortly before and during the Second World War, Japanese doctors and medical researchers conducted large-scale human experiments in occupied China that were at least as gruesome as those conducted by Nazi doctors. Japan never officially acknowledged the occurrence of the experiments, never tried any of the perpetrators, and never provided compensation to the victims or issued an apology. Building on work by Jing-Bao Nie, this article argues that the U.S. government is heavily complicit in this grave injustice, and should respond in an appropriate way in order to reduce this complicity, as well as to avoid complicity in future unethical medical experiments. It also calls on other U.S. institutions, in particular the Presidential Commission for the Study of Bioethical Issues, to urge the government to respond, or to at least inform the public and initiate a debate about this dark page of American and Japanese history.

Role of AMPK in Diabetic Cardiovascular Complications: An Overview.

Kumar, Ashutosh; Nellaiappan, Karthika; Yerra, Veera Ganesh

2018-05-07

Macrovascular complications of diabetes like cardiovascular diseases appear to be one of the leading causes of mortality. Current therapies aimed at counteracting the adverse effects of diabetes on cardiovascular system are found to be inadequate. Hence, there is growing need in search of novel targets. Adenosine monophosphate activated protein kinase (AMPK) is one such promising target, as a plethora of evidences point to its cardioprotective role in pathological milieu like cardiac hypertrophy, atherosclerosis and heart failure. AMPK is a serine-threonine kinase, which gets activated in response to a cellular depriving energy status. It orchestrates cellular metabolic response to energy demand and is, therefore, often referred to as "metabolic master switch" of the cell. In this review, we provide an overview of patho-mechanisms of diabetic cardiovascular disease; highlighting the role of AMPK in the regulation of this condition, followed by a description of extrinsic modulators of AMPK as potential therapeutic tools.

Carotenoids are a large class of natural antioxidants that occur in many vegetables, foods and other natural sources. To date, a large number of biological properties have been reported from carotenoids, particularly protective effects against diabetes mellitus (DM), cancer, and neurodegenerative, metabolic and cardiovascular diseases. However, recent studies including clinical evidences, have shown that carotenoids play a role in the treatment of diabetes via enhancing insulin sensitivity. They are also able to protect the body from long-term consequences of diabetes including infectious diseases, nephropathy, neuronal and eye abnormalities. In this review, we try to discuss the mechanisms behind the biological effects of carotenoids for the prevention and treatment of DM and its complications. The authors believe that carotenoids will have a prominent place in the treatment of DM and its complications in the future. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

The increasing prevalence of diabetes and its related complications is raising the need for effective methods to predict patient evolution and for stratifying cohorts in terms of risk of developing diabetes-related complications. In this paper, we present a novel approach to the simulation of a type 1 diabetes population, based on Dynamic Bayesian Networks, which combines literature knowledge with data mining of a rich longitudinal cohort of type 1 diabetes patients, the DCCT/EDIC study. In particular, in our approach we simulate the patient health state and complications through discretized variables. Two types of models are presented, one entirely learned from the data and the other partially driven by literature derived knowledge. The whole cohort is simulated for fifteen years, and the simulation error (i.e. for each variable, the percentage of patients predicted in the wrong state) is calculated every year on independent test data. For each variable, the population predicted in the wrong state is below 10% on both models over time. Furthermore, the distributions of real vs. simulated patients greatly overlap. Thus, the proposed models are viable tools to support decision making in type 1 diabetes. Copyright © 2015 Elsevier Inc. All rights reserved.

Low Peripheral Nerve Conduction Velocities and Amplitudes Are Strongly Related to Diabetic Microvascular Complications in Type 1 Diabetes

OBJECTIVE Slow nerve conduction velocity and reduction in response amplitude are objective hallmarks of diabetic sensorimotor polyneuropathy. Because subjective or clinical indicators of neuropathy do not always match well with the presence of abnormal nerve physiology tests, we evaluated associations to nerve conduction in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS Nerve conduction studies were performed in the distal sural and ulnar sensory nerves and the peroneal motor nerve in 456 individuals with type 1 diabetes who participated in the follow-up visit of the EURODIAB Prospective Complications Study (EPCS). We used multivariate regression models to describe associations to decreased nerve conduction measures. RESULTS In addition to an effect of duration of diabetes and A1C, which were both associated with low nerve conduction velocity and response amplitude, we found that the presence of nephropathy, retinopathy, or a clinical diagnosis of neuropathy was associated with low nerve conduction velocity and amplitude. In the case of nonproliferative retinopathy, the odds ratio (OR) for being in lowest tertile was 2.30 (95% CI 1.13–4.67) for nerve conduction velocity. A similar OR was found for each 2% difference in A1C (2.39 [1.68–3.41]). CONCLUSIONS We show that the presence of other microvascular diabetes complications, together with diabetes duration and A1C, are associated with low nerve conduction velocity and amplitude response and that cardiovascular disease or risk factors do not seem to be associated with these measures.

Diabetic complications is a complex metabolic disorder developed primarily due to prolonged hyperglycemia in the body. The complexity of the disease state as well as the unifying pathophysiology discussed in the literature reports exhibited that the use of multi-targeted agents with multiple complementary biological activities may offer promising therapy for the intervention of the disease over the single-target drugs. In the present study, novel thiazolidine-2,4-dione analogues were designed as multi-targeted agents implicated against the molecular pathways involved in diabetic complications using knowledge based as well as in-silico approaches such as pharmacophore mapping, molecular docking etc. The hit molecules were duly synthesized and biochemical estimation of these molecules against aldose reductase (ALR2), protein kinase Cβ (PKCβ) and poly (ADP-ribose) polymerase 1 (PARP-1) led to identification of compound 2 that showed good potency against PARP-1 and ALR2 enzymes. These positive results support the progress of a low cost multi-targeted agent with putative roles in diabetic complications. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective. Treating complications associated with diabetes and hypertension imposes significant costs on health care systems. This study estimated the hospitalization costs for inpatients in a public hospital in Zimbabwe. Methods. The study was retrospective and utilized secondary data from medical records. Total hospitalization costs were estimated using generalized linear models. Results. The median cost and interquartile range (IQR) for patients with diabetes, $994 (385–1553) mean $1319 (95% CI: 981–1657), was higher than patients with hypertension, $759 (494–1147) mean $914 (95% CI: 825–1003). Female patients aged below 65 years with diabetes had the highest estimated mean costs ($1467 (95% CI: 1177–1828)). Wound care had the highest estimated mean cost of all procedures, $2884 (95% CI: 2004–4149) for patients with diabetes and $2239 (95% CI: 1589–3156) for patients with hypertension. Age below 65 years, medical procedures (amputation, wound care, dialysis, and physiotherapy), the presence of two or more comorbidities, and being prescribed two or more drugs were associated with significantly higher hospitalization costs. Conclusion. Our estimated costs could be used to evaluate and improve current inpatient treatment and management of patients with diabetes and hypertension and determine the most cost-effective interventions to prevent complications and comorbidities.

Neurological complications of diabetic ketoacidosis are considered to be very serious clinical problem. The most common complication is cerebral edema. However this group includes also less common syndromes such as ischemic or hemorrhagic stroke, cerebral venous and sinus thrombosis or very rare peripheral neuropathy. We present a case of 9-year old girl with new onset type 1 diabetes, diabetic ketoacidosis, cerebral edema, multifocal vasogenic brain lesions and lower limbs peripheral paresis. The patient developed polydipsia and polyuria one week before admission to the hospital. In laboratory tests initial blood glucose level 1136 mg/dl and acidosis (pH 7.1; BE-25.9) were noted. She was admitted to the hospital in a critical condition and required treatment in intensive care unit. Computed tomography scan showed brain edema and hipodense lesion in the left temporal region. Brain MRI revealed more advanced multifocal brain lesions Nerve conduction studies demonstrated damage of the motor neuron in both lower extremities with dysfunction in both peroneal nerves and the right tibial nerve. As a result of diabetological, neurological treatment and physiotherapy patient's health state gradually improved. Acute neuropathy after ketoacidosis is rare complication and its pathomechanism is not clear. Patients with DKA require careful monitoring of neurological functions even after normalization of glycemic parameters.

Cinnamic Acid and Its Derivatives: Mechanisms for Prevention and Management of Diabetes and Its Complications.

2017-02-21

With recent insight into the development of dietary supplements and functional foods, search of effective phytochemical compounds and their mechanisms involved in prevention and management of diabetes and its complications are now being assessed. Cinnamic acid and its derivatives occur naturally in high levels of plant-based foods. Among various biological activities, cinnamic acid and its derivatives are associated with a beneficial influence on diabetes and its complications. The aim of the review is to summarize the potential mechanisms of these compounds for prevention and management of diabetes and its complications. Based on several in vitro studies and animal models, cinnamic acid and its derivatives act on different mechanism of actions, including stimulation of insulin secretion, improvement of pancreatic β-cell functionality, inhibition of hepatic gluconeogenesis, enhanced glucose uptake, increased insulin signaling pathway, delay of carbohydrate digestion and glucose absorption, and inhibition of protein glycation and insulin fibrillation. However, due to the limited intestinal absorption being a result of low bioavailability of cinnamic acid and its derivatives, current improvement efforts with entrapping into solid and liquid particles are highlighted. Further human clinical studies are needed to clarify the effects of cinnamic acid and its derivatives in diabetic patients.

The objective of this study was to assess the current relationship between certain demographics and chemical factors, and the risk of cardiovascular complications, within a Puerto Rican population with diabetes mellitus. A total of 2075 patients with diabetes mellitus were retrospectively evaluated to determine the influence of certain demographics and chemical variables on the appearance of cardiovascular complications. A group of demographic and laboratory variables were analyzed. Our sample was obtained, based on convenience, from an endocrinologist's office in an area of about 250 000 people. All the patients met the American Diabetes Association (ADA) definitions for diabetes mellitus. The study covered a time period of 8 years. The patients signed an informed consent document at their first office visit. Data were obtained by the endocrinologist in charge. We considered the demographic variables of sex, age, time with diabetes, lipid profile, metabolic control (measured with glycated hemoglobin levels), and microalbumin renal excretion. Cardiovascular complications were more prevalent in patients with poor metabolic control, those with prolonged disease duration, men, and patients who were more than 50 years of age. We found no relationship between cardiovascular disease, systolic blood pressure over 130 mm Hg, body mass index and low-density lipoprotein cholesterol levels over 100 mg/dL. In Puerto Rican patients with diabetes mellitus, there is a statistically significant relationship between patient's gender, age, disease duration, glycemic control and increased kidney microalbumin excretion with cardiovascular complications.

We present a computerized system for the assessment of the long-term risk of developing diabetes-related complications. The core of the system consists of a set of predictive models, developed through a data-mining/machine-learning approach, which are able to evaluate individual patient profiles and provide personalized risk assessments. Missing data is a common issue in (electronic) patient records, thus the models are paired with a module for the intelligent management of missing information. The system has been deployed and made publicly available as Web service, and it has been fully integrated within the diabetes-management platform developed by the European project REACTION. Preliminary usability tests showed that the clinicians judged the models useful for risk assessment and for communicating the risk to the patient. Furthermore, the system performs as well as the United Kingdom Prospective Diabetes Study (UKPDS) Risk Engine when both systems are tested on an independent cohort of UK diabetes patients. Our work provides a working example of risk-stratification tool that is (a) specific for diabetes patients, (b) able to handle several different diabetes related complications, (c) performing as well as the widely known UKPDS Risk Engine on an external validation cohort.

To investigate the distribution features of Chinese medical constitutions in hypertension complicated diabetes patients. Recruited were 251 primary hypertension inpatients at the Department of Neurology and the Department of Cardiology, Mindong Hospital of Ningde City from October 2010 to March 2011. They were assigned to two groups according to whether they were complicated with diabetes, i.e., the primary hypertension complicated diabetes (as the case group, 78 cases) and the primary hypertension without complicated diabetes (as the control group, 173 cases). The constitution types were investigated by questionnaire. The constitution type distribution was compared between the two groups. The data including gender, age, and the distribution of the constitution type were compared between the two groups. The levels of TG, TC, LDL-C, Hb, FPG, and ALB were detected on the 2nd day after admission. The levels of TG, TC, LDL-C, Hb, and ALB were compared be- tween the two groups in patients of yin deficiency constitution, phlegm dampness constitution, and qi deficiency constitution. There was no statistical difference in the hypertension grading, the disease course, and chronic disease complications between the two groups (P > 0.05). The main constitution types were yin deficiency (accounting for 26.0%), phlegm dampness (accounting for 19.1%), and qi deficiency (accounting for 19.1%) in the control group. The main constitution types were yin deficiency (accounting for 32.1%), phlegm dampness (accounting for 30.8%), and qi deficiency (accounting for 17.9%) in the case group. The ratio of phlegm dampness type in the case group was higher than that in the control group with statistical difference (P = 0.041). There was no statistical difference in the constitution distribution in the same gender between the two groups (P > 0.05). There was no statistical difference in the constitution distribution in those younger than 80 years between the two groups (P > 0.05). Compared

The association between time spent walking and risk of diabetes was investigated in a Japanese population-based cohort. Data from the Japan Public Health Center-based Prospective Diabetes cohort were analyzed. The surveys of diabetes were performed at baseline and at the 5-year follow-up. Time spent walking per day was assessed using a self-reported questionnaire (<30 minutes, 30 minutes to <1 hour, 1 to <2 hours, or ≥2 hours). A cross-sectional analysis was performed among 26 488 adults in the baseline survey. Logistic regression was used to examine the association between time spent walking and the presence of unrecognized diabetes. We then performed a longitudinal analysis that was restricted to 11 101 non-diabetic adults who participated in both the baseline and 5-year surveys. The association between time spent walking and the incidence of diabetes during the 5 years was examined. In the cross-sectional analysis, 1058 participants had unrecognized diabetes. Those with time spent walking of <30 minutes per day had increased odds of having diabetes in relation to those with time spent walking of ≥2 hours (adjusted odds ratio [OR] 1.23; 95% CI, 1.02-1.48). In the longitudinal analysis, 612 participants developed diabetes during the 5 years of follow-up. However, a significant association between time spent walking and the incidence of diabetes was not observed. Increased risk of diabetes was implied in those with time spent walking of <30 minutes per day, although the longitudinal analysis failed to show a significant result.

To study the impact of glycaemic control on urinary incontinence in women who participated in the Diabetes Control and Complications Trial (DCCT; 1983-1993) and its observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC; 1994-present). Study participants were women who completed, at both years 10 (2003) and 17 (2010) of the EDIC follow-up, the urological assessment questionnaire (UroEDIC). Urinary incontinence was defined as self-reported involuntary leakage of urine that occurred at least weekly. Incident urinary incontinence was defined as weekly urinary incontinence present at EDIC year 17 but not at EDIC year 10. Multivariable regression models were used to examine the association of incident urinary incontinence with comorbid prevalent conditions and glycaemic control (mean HbA 1c over the first 10 years of EDIC). A total of 64 (15.3%) women with Type 1 diabetes (mean age 43.6 ± 6.3 years at EDIC year 10) reported incident urinary incontinence at EDIC year 17. When adjusted for clinical covariates (including age, DCCT cohort assignment, DCCT treatment arm, BMI, insulin dosage, parity, hysterectomy, autonomic neuropathy and urinary tract infection in the last year), the mean EDIC HbA 1c was associated with increased odds of incident urinary incontinence (odds ratio 1.03, 95% CI 1.01-1.06 per mmol/mol increase; odds ratio 1.41, 95% CI 1.07-1.89 per % HbA 1c increase). Incident urinary incontinence was associated with higher HbA 1c levels in women with Type 1 diabetes, independent of other recognized risk factors. These results suggest the potential for women to modify their risk of urinary incontinence with improved glycaemic control.

Background Foot ulceration is a major health problem for people with diabetes. To minimise the risk of ulceration, patients are advised to perform preventive foot self-care. Aim To explore beliefs about diabetic foot complications and everyday foot self-care practices among people with type 2 diabetes. Design of study Qualitative study using one-to-one interviews. Setting A suburban primary care health centre. Method Semi-structured interviews with a purposive sample of adults with type 2 diabetes but with no experience of foot ulceration. Results Most participants were unsure of what a foot ulcer is and unaware of the difficulties associated with ulcer healing. Prevention of accidental damage to the skin was not considered a priority, as few participants knew that this is a common cause of foot ulceration. Although it was recognised that lower-limb amputation is more common in people with diabetes, this was perceived to be predominantly caused by poor blood supply to the feet and unrelated to foot ulceration. Therefore, preventive foot care focused on stimulating blood circulation, for example by walking barefoot. Consequently, some of the behaviours participants considered beneficial for foot health could potentially increase the risk of ulceration. In some cases the uptake of advice regarding preventive foot care was hampered because participants found it difficult to communicate with health professionals. Conclusion Patients with type 2 diabetes may have beliefs about foot complications that differ from medical evidence. Such illness beliefs may play a role in foot-related behaviours that have previously been unrecognised. Health professionals need to explore and address the beliefs underlying patients' foot self-care practices. PMID:18682014

The naturally inspired treatment options for several disease conditions and human-health related disorders such as diabetes mellitus have gained considerable research interest. In this context, naturally occurring plants and herbs with medicinal functionalities have gained special place than ever before in the current medicinal world. The objective of this review is to extend the current knowledge in the clinical field related to the diabetic complications. A special focus has also been given to the anti-diabetic potentialities of ethnomedicinal plants. Herein, we reviewed and compiled salient information from the authentic bibliographic databases including PubMed, Scopus, Elsevier, Springer, Bentham Science and other scientific databases. The patents were searched and reviewed from http://www.freepatentsonline.com. Diabetes mellitus is a group of metabolic disorders associated with the endocrine system that resulted in hyperglycemic conditions. Metabolic disorders can cause many complications such as neuropathy, retinopathy, nephropathy, ischemic heart disease, stroke, and microangiopathy. Traditional botanical therapies have been used around the world to treat diabetes. Among several medications and different medicines, various herbs are known to cure and control diabetes; also have no side effects. History has shown that medicinal plants have long been used for traditional healing around the world to treat diabetes. More than 800 plants around the world are shown by ethnobotanical information as traditional remedies for the treatment of diabetes. Several parts of these plants have been evaluated and appreciated for hypoglycemic activity. Medicinal plants have been found to be more effective than conventional drug compounds with no/fewer side effects and relatively inexpensive. In this review paper, we have reviewed plants with anti-diabetic and related beneficial medicinal effects. This review may be helpful for researchers, diabetic patient and decision makers

Patient preferences for diabetes-related complications in Taiwan.

As the prevalence of diabetes mellitus (DM) continues to increase rapidly, there has been a rising need not only to assess the clinical outcomes but also the impact of DM on the health-related quality of life (HRQoL) of affected individuals. Most previous studies have found that having complications is strongly associated with decreased HRQoL in DM patients. As such, it is crucial to measure individuals' preferences for DM-related complications in order to assess the magnitude of complications' effect on overall HRQoL. In addition, preference scores are an essential component of cost-utility analyses (CUAs), which studies can incorporate healthcare costs, HRQoL and clinical outcomes of DM into one analysis. The aims of this study were to assess the preference scores of DM-related complications using both the standard gamble (SG), a choice-based method, and visual analogue scale (VAS), a scaling method. We also aimed to assess several possible factors that might be associated with the preference scores of the complications. This is a cross-sectional interview-administered survey, and 213 patients with type 2 DM were interviewed. The respondents' preference scores of eleven DM-related complications were obtained using VAS and SG techniques. Demographic information, clinical characteristics and risk attitudes were also collected to explore factors that may affect patients' preference scores. Nearly one quarter of participants in Taiwan ranked at least one of the complications worse than death. The mean VAS scores ranged from 0.004 (amputation) to 0.47 (nocturnal hypoglycemia) while the mean adjusted SG scores ranged from 0.30 (blindness) to 0.66 (nocturnal hypoglycemia). There were significant differences in all of the complications' preference scores depending on risk attitudes. Both the VAS and SG methods were used to elicit the preference scores of DM-related complications, and the preference scores derived could be useful for future cost utility analyses.

There is little data on the incidence of diabetes complications in young onset type 1 diabetes (T1DM) and type 2 diabetes (T2DM) in non European populations. From a tertiary diabetes centre, Chennai, India, we recruited 108 T1DM (defined by abrupt onset of symptoms or diabetic ketoacidosis, absent insulin reserve requiring insulin treatment) and 90 T2DM participants (defined by absence of ketosis, good beta-cell reserve, and good response to oral agents) who were diagnosed between the ages of 10 and 25years, and without any evidence of diabetes complications at diagnosis. We estimated the incidence of various complications (median follow up of five years); retinopathy was defined by presence of at least one definite microaneurysm by retinal photography, nephropathy by urinary albumin excretion ⩾30μg/mg of creatinine, neuropathy by vibration perception threshold ⩾20V on biothesiometry, peripheral vascular disease by an ankle-brachial index <0.9, and ischemic heart disease (IHD) by history of myocardial infarction or coronary revascularization or Q waves on ECG or on drug treatment for IHD. The mean ages at diagnosis of T1DM and T2DM participants were 17.1±4.2vs. 21.6±3.6years respectively. The incidence of various complications reported in numbers/1000 person years of follow up of T1DM and T2DM were: retinopathy 77.4vs. 78.0/1000 person years, nephropathy, 62.0vs. 58.8, neuropathy 7.8 vs. 13.9 and ischemic heart disease 1.2vs. 5.4. In Cox regression analysis, after adjustment for age, glycated hemoglobin, systolic blood pressure and serum cholesterol, T2DM participants had 2.11 times (95%CI: 1.27-3.51) higher risk of developing any diabetes complication, compared to T1DM. Young-onset T2DM have a more aggressive disease course than T1DM. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

2015-01-01

Lithium-associated hyperparathyroidism is the leading cause of hypercalcemia in lithium-treated patients. Lithium may lead to exacerbation of pre-existing primary hyperparathyroidism or cause an increased set-point of calcium for parathyroid hormone suppression, leading to parathyroid hyperplasia. Lithium may cause renal tubular concentration defects directly by the development of nephrogenic diabetes insipidus or indirectly by the effects of hypercalcemia. In this study, we present a female patient on long-term lithium treatment who was evaluated for hypercalcemia. Preoperative imaging studies indicated parathyroid adenoma and multinodular goiter. Parathyroidectomy and thyroidectomy were planned. During the postoperative course, prolonged intubation was necessary because of agitation and delirium. During this period, polyuria, severe dehydration, and hypernatremia developed, which responded to controlled hypotonic fluid infusions and was unresponsive to parenteral desmopressin. A diagnosis of nephrogenic diabetes insipidus was apparent. A parathyroid adenoma and multifocal papillary thyroid cancer were detected on histopathological examination. It was thought that nephrogenic diabetes insipidus was masked by hypercalcemia preoperatively. A patient on lithium treatment should be carefully followed up during or after surgery to prevent life-threatening complications of previously unrecognized nephrogenic diabetes insipidus, and the possibility of renal concentrating defects on long-term lithium use should be sought, particularly in patients with impaired consciousness.

Aims To define and agree a practical educational framework for delivery by all healthcare professionals managing patients with diabetes, particularly those at low risk of developing foot complications. Methods A consensus meeting of a multidisciplinary expert panel. Prior to the meeting, relevant clinical papers were disseminated to the panel for review. The consensus was largely based upon the experts’ clinical experience and judgement. Results Four main health behaviours were identified for those at low risk of developing foot complications, namely:, control of blood glucose levels; attendance at annual foot screening examination; reporting of any changes in foot health immediately; and the engagement in a simple daily foot care routine. Conclusion There is currently little evidence-based literature to support specific foot care practices. Patients with diabetes at low risk of developing complications should be encouraged to undertake a basic foot care regimen to reduce their likelihood of developing complications. PMID:21219423

To evaluate the use of live volumetric (4D) intraoperative swept-source microscope-integrated optical coherence tomography in vitrectomy for proliferative diabetic retinopathy complications. In this prospective study, we analyzed a subgroup of patients with proliferative diabetic retinopathy complications who required vitrectomy and who were imaged by the research swept-source microscope-integrated optical coherence tomography system. In near real time, images were displayed in stereo heads-up display facilitating intraoperative surgeon feedback. Postoperative review included scoring image quality, identifying different diabetic retinopathy-associated pathologies and reviewing the intraoperatively documented surgeon feedback. Twenty eyes were included. Indications for vitrectomy were tractional retinal detachment (16 eyes), combined tractional-rhegmatogenous retinal detachment (2 eyes), and vitreous hemorrhage (2 eyes). Useful, good-quality 2D (B-scans) and 4D images were obtained in 16/20 eyes (80%). In these eyes, multiple diabetic retinopathy complications could be imaged. Swept-source microscope-integrated optical coherence tomography provided surgical guidance, e.g., in identifying dissection planes under fibrovascular membranes, and in determining residual membranes and traction that would benefit from additional peeling. In 4/20 eyes (20%), acceptable images were captured, but they were not useful due to high tractional retinal detachment elevation which was challenging for imaging. Swept-source microscope-integrated optical coherence tomography can provide important guidance during surgery for proliferative diabetic retinopathy complications through intraoperative identification of different complications and facilitation of intraoperative decision making.

to study peculiarities of primary and recurrent disability due to ocular complications of diabetes in Tashkent over the years 2003-2012 and to assess the impact of risk factors on the effectiveness of laser photocoagulation of the retina. A total of 347 disability examination reports of diabetic patients with ocular complications were copied and 48 case histories of patients with type II diabetes who underwent laser photocoagulation of the retina - retrospectively analyzed. Stabilization of visual function was used as the effectiveness criterion. The rate of new cases of disability over the studied decade averaged 0.55 per 100,000 population per year, while that of recurrent disability was 1.8 times higher - 0.97. The overall rate of disability was not high - 1.53; at that, severe disability (i.e. grade I and II) prevailed. Both recurrent and primary disability groups were made up by middle-aged patients and those in their retirement age; however, in the recurrent disability group the number of young disabled people was 4.5 times higher than in the primary disability group. Studies of the effectiveness of laser photocoagulation of the retina in relation to the compensation of diabetes and blood pressure level showed that unstable general condition was associated with not only significant deterioration of visual function, but also complications, including severe. The rate of disability due to ocular complications of diabetes is generally not high, however, grades I and II disabilities that require greater social support has been found to prevail in both groups. Most of disabled people are middle-aged (working-age population), which also causes economic damage. In cases of decompensated diabetes and unstable blood pressure, the effectiveness of laser photocoagulation of the retina is reduced.

Traditional Chinese medicine (TCM) is an important complementary strategy for treating diabetes mellitus (DM) in China. Traditional Chinese blood circulation activating drugs are intended to guide an overall approach to the prevention and treatment of microvascular complications of DM. The core mechanism is related to the protection of the vascular endothelium and the basement membrane. Here, we reviewed the scientific evidence underpinning the use of blood circulation activating drugs to prevent and treat DM-induced microvascular complications, including diabetic nephropathy (DN), diabetic peripheral neuropathy (DPN), and diabetic retinopathy (DR). Furthermore, we summarized the effects and mechanism of TCM on improving blood rheology, inhibiting aggregation of platelet, forming advanced glycation end products (AGEs), regulating oxidative stress, reducing blood fat, and improving lipid metabolism. The paper provides a new theoretical basis for the clinical practice of TCM in the prevention and treatment of DM and its microvascular complications.

Background The aim of this study was to determine the incidence of complications associated with primary closure in surgical procedures performed for diabetic foot osteomyelitis compared to those healed by secondary intention. In addition, further evaluation of the surgical digital debridement for osteomyelitis with primary closure as an alternative to patients with digital amputation was also examined in our study. Methods Comparative study that included 46 patients with diabetic foot ulcerations. Surgical debridement of the infected bone was performed on all patients. Depending on the surgical technique used, primary surgical closure was performed on 34 patients (73.9%, Group 1) while the rest of the 12 patients were allowed to heal by secondary intention (26.1%, Group 2). During surgical intervention, bone samples were collected for both microbiological and histopathological analyses. Post-surgical complications were recorded in both groups during the recovery period. Results The average healing time was 9.9±SD 8.4 weeks in Group 1 and 19.1±SD 16.9 weeks in Group 2 (p=0.008). The percentage of complications was 61.8% in Group 1 and 58.3% in Group 2 (p=0.834). In all patients with digital ulcerations that were necessary for an amputation, a primary surgical closure was performed with successful outcomes. Discussion Primary surgical closure was not associated with a greater number of complications. Patients who received primary surgical closure had faster healing rates and experienced a lower percentage of exudation (p=0.05), edema (p<0.001) and reinfection, factors that determine the delay in wound healing and affect the prognosis of the surgical outcome. Further research with a greater number of patients is required to better define the cases for which primary surgical closure may be indicated at different levels of the diabetic foot. PMID:23050062

This study investigated the relationship among β-cell function, metabolic control, and diabetic microvascular complications in patients with type 2 diabetes mellitus (T2DM). In total, 885 patients with type 2 diabetes mellitus (DM) were recruited from January 2012 to January 2014 and grouped into three groups according to the area under the curve of C-peptide [AUC(C-pep)] during the 75-g oral glucose tolerance test. Logistic regression analyses were used to evaluate the association between C-peptide and microvascular complications. The prevalence of diabetic microvascular complications decreased from the first to the third AUC(C-pep) tertile (P < 0.01 for all), whereas the rates of nonalcoholic fatty liver disease (NAFLD) was positively associated with AUC(C-pep) values. Patients with lower AUC(C-pep) tertile exhibited higher levels of glycosylated hemoglobin and high-density lipoprotein cholesterol and longer duration of DM; however, levels of triglycerides, fasting C-peptide, 2-h C-peptide, body mass index, and homeostasis model assessment of insulin resistance index were lower compared with the third tertile. Comparison among patients with a similar DM duration showed a higher level of AUC(C-pep) was inversely associated with prevalence of microvascular complications. The odds ratios for nephropathy, retinopathy, and neuropathy in the lowest versus the highest AUC(C-pep) tertile were 3.10 (95% confidence interval, 2.01-4.78), 2.83 (1.73-4.64), and 2.04 (1.37-3.04) after adjustment for confounding factors. Higher AUC(C-pep) levels were associated with a decreased prevalence of microvascular complications and a good level of glycemic control, whereas higher endogenous insulin levels were linked to the components of metabolic syndrome and increased rates of NAFLD.

We estimated the cumulative risk of type 2 diabetes from age 30 to 65 years in a large working population in Japan. We used data from the Japan Epidemiology Collaboration on Occupational Health Study. Participants (46,065 men and 7,763 women) were aged 30-59 years, free of diabetes at baseline, and followed up for a maximum of 7 years. Incident type 2 diabetes was defined based on fasting and casual glucose, glycated hemoglobin, and current medical treatment for type 2 diabetes. We calculated the sex-specific cumulative risk of type 2 diabetes using the Practical Incidence Estimator macro, which was created to produce several estimates of disease incidence for prospective cohort studies based on a modified Kaplan-Meier method. During 274,349 person-years of follow-up, 3,587 individuals (3,339 men and 248 women) developed type 2 diabetes. The cumulative risk was 34.7% (95% confidence interval, 33.1-36.3%) for men and 18.6% (95% confidence interval, 15.5-21.7%) for women. In BMI-stratified analysis, obese (BMI ≥30 kg/m 2 ) and overweight (BMI 25-29.9 kg/m 2 ) men and women had a much higher cumulative risk of type 2 diabetes (obese: 77.3% for men and 64.8% for women; overweight: 49.1% and 35.7%, respectively) than those with BMI <25 kg/m 2 (26.2% and 13.4% for men and women, respectively). The present data highlight the public health burden of type 2 diabetes in the working population. There is a need for effective programs for weight management and type 2 diabetes screening, especially for young obese employees, to prevent or delay the development of type 2 diabetes.

Objective To investigate whether there is a difference in balance function between older persons with and without diabetes mellitus (DM), and to identify whether mediating factors, such as diabetic complications, Instrumental Activities of Daily Living (IADL) score, Mini-Mental State Examination (MMSE) score, as well as hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein (LDL), are associated with balance function in older persons with DM. Methods In this cross-sectional study, a total of 208 older persons were divided into a DM group (n=80) and a control group who did not have DM (n=128). Balance function was evaluated with the Tinetti performance-oriented mobility assessment (POMA), which includes balance and gait subscales. Activities of daily living (ADL), IADL, and the MMSE were also measured. Fall incidents in last 12 months, the use of walking aids, fear of falling, comorbidities, and polypharmacy were recorded. Diabetic complications were recorded, and HbA1c, FPG, TC, TG, and LDL were measured in the patients of the DM group. Results Fall incidents in last 12 months were higher in the DM group than in the control group (P<0.01). POMA score as well as ADL and IADL scores were lower in the diabetic group than the control group (P<0.05). Within the diabetic group, the POMA score was positively related to the ADL score (odds ratio [OR], 11.7; 95% confidence interval [CI], 3.076–44.497; P<0.01), IADL score (OR, 16.286; 95% CI, 4.793–55.333; P<0.01), and MMSE score (OR, 10.524; 95% CI, 2.764–40.074; P<0.01), but was negatively related to age (OR, 7.707; 95% CI, 2.035–29.185; P<0.01) and diabetic complication (OR, 6.667; 95% CI, 2.279–19.504; P<0.01). Also, within the DM group, the decreased POMA score was associated with multiple diabetic complications (OR, 5.977; 95% CI, 1.378–25.926; P<0.05), decreased IADL score (OR, 10.288; 95% CI, 2.410–43.915; P<0.01), and MMSE

The relationship between skin diseases and extracutaneous complications in diabetes mellitus (DM) is unclear. We aimed to investigate the relationship between skin disorders and diabetic neuropathy, nephropathy, and retinopathy in patients with DM. A total of 750 patients with DM were prospectively enrolled. Demographic and clinical features, skin disorders, glycosylated hemoglobin (HbA1c) levels, and presence of nephropathy, neuropathy, and retinopathy were noted. Of the patients, 38.0% had neuropathy, 23.3% had nephropathy, and 22.9% had retinopathy. Any skin disorder was present in 79.2% (n = 594) of patients. The most common skin manifestations were cutaneous infections (47.5%), xerosis (26.4%), and inflammatory skin diseases (20.7%). The frequency of cutaneous infections, fungal infections, diabetic foot, rubeosis faciei, and pigmented purpuric dermatitis was higher in patients with nephropathy than in those without nephropathy. Cutaneous infections, diabetic foot, rubeosis faciei, and diabetic dermopathy were more common in patients with neuropathy. Fungal infections, diabetic foot, rubeosis faciei, diabetic dermopathy, and pigmented purpuric dermatitis were more frequent in patients with retinopathy. Patients with HbA1c ≥8 mmol/mL had more skin disorders than those with HbA1c <8 mmol/mL (P < 0.05 for all). Skin disorders may be clues to the presence of associated microvascular complications of DM.

Objectives To evaluate the clinical management of type 2 diabetes in the Eeyou Istchee communities of northern Quebec. Study design Retrospective quality assurance audit. Methods Patients with diabetes were identified using the Cree Diabetes Information System. Charts of eligible patients were audited for healthcare visits, glycemic control, blood pressure, lipid profile, pharmacological treatment and complications for the 2006 calendar year. Analyses were performed to assess the association of disease duration, age, target glycemic and blood pressure control with diabetes complications. Results Half of the patients (49.7%) achieved target HbA1c, 53.6% had a blood pressure of ≤130/80 and 58.7% had an LDL of ≤2.5 mmol/L. The proportion of patients meeting all 3 targets was low at 17.1%. The mean number of diabetes-related clinic visits was high, with an average of 3.9 visits to a physician and an average of 8.7 visits to a registered nurse. Of patients with a documented diabetic complication, 39.4% of patients were not being managed with an ACE/ARB and 48.2% of patients were not prescribed a statin. Conclusions These findings suggest a possible treatment gap for risk factors and complications management. To circumvent further increases in diabetes-related complications, emphasis should be placed on improved healthcare worker training, greater use of clinical management and patient education tools and improved communication during the diabetes-related clinical visits. Development of a culturally appropriate multidisciplinary approach towards improved understanding of diabetes and multifactorial risk management for diabetic patients is essential for the prevention of diabetic complications.

Increased lipoprotein (a) serum concentrations seems to be a cardiovascular risk factor; this has not been confirmed in extracoronary atherosclerosis complications. We therefore wished to gain a deeper insight into relationship between the plasma concentrations of lipoprotein (a) and the micro- and macro-vascular complications of type 2 diabetes mellitus and to identify possible differences in this association. This is a descriptive observational cross-sectional study. Two-hundred and seventeen elderly patients with type 2 diabetes mellitus were included from the internal medicine outclinic. Anthropometric data, analytical data (insulin reserve, basal and postprandial peptide C, glycosylated hemoglobin, renal parameters, lipid profile and clinical data as hypertension, obesity, micro- and macrovascular complications were collected. Patients were grouped according to the type 2 diabetes mellitus time of evolution. The mean plasma concentration of lipoprotein (a) was 22.2 ± 17.3 mg/dL (22.1 ± 15.9 mg/dL for males, and 22.1 ± 18.4 mg/dL for females). Patients with hypertension, coronary heart disease, cerebrovascular accident, microalbuminuria and proteinuria presented a statistically significant increased level of lipoprotein (a). Similarly, the patients with hyperlipoprotein (a) (≥ 30 mg/dL) presented significantly increased levels of urea and total cholesterol. In the multivariate regression model, the level of lipoprotein (a) is positively correlated with coronary heart disease and diabetic nephropathy (P < 0.01 and P < 0.005, respectively). The elevation of plasma levels of lipoprotein (a) are associated with the development of coronary heart disease and diabe tic nephropathy. Therefore, we consider that the determination of lipoprotein (a) may be a prognostic marker of vascular complications in patients with type 2 diabetes mellitus.

The aim of the present study was to test a hypothesis that a history of having a macrosomic infant (≥ 4000 g) is associated with the risk of diabetes. Data on the Japan Public Health Center-based Prospective diabetes cohort were analyzed, which is a population-based cohort study on diabetes. The survey of diabetes was performed at baseline and at the 5-year follow-up. A history of having a macrosomic infant was assessed using a self-administered questionnaire. A cross-sectional analysis was performed among 12,153 women who participated in the 5-year survey of the cohort. Logistic regression was used to examine the relationship between a history of having a macrosomic infant and the presence of diabetes. A longitudinal analysis was also conducted among 7,300 women without diabetes who participated in the baseline survey. Logistic regression was used to investigate the relationship between a history of having a macrosomic infant and the incidence of diabetes between the baseline survey and the 5-year survey. In the cross-sectional analysis, parous women with a positive history were more likely to have diabetes in relation to parous women without (OR = 1.44, 95% CI = 1.13-1.83). The longitudinal analysis showed a modest but non-significant increased risk of developing diabetes among women with a positive history (OR = 1.24, 95% CI = 0.80-1.94). An increased risk of diabetes was implied among women with a history of having a macrosomic infant although the longitudinal analysis showed a non-significant increased risk.

The risk of cardiovascular events in humans increases in the presence of type 1 or type 2 diabetes mellitus, in large part due to exacerbated atherosclerosis. Genetically engineered mouse models have begun to elucidate cellular and molecular mechanisms responsible for diabetes-exacerbated atherosclerosis. Research on these mouse models has revealed that diabetes independently accelerates initiation and progression of lesions of atherosclerosis and also impairs the regression of lesions following aggressive lipid lowering. Myeloid cell activation in combination with proatherogenic changes allowing for increased monocyte recruitment into arteries of diabetic mice has emerged as an important mediator of the effects of diabetes on the three stages of atherosclerosis. The effects of diabetes on atherosclerosis appear to be dependent on an interplay between glucose and lipids, as well as other factors, and result in increased recruitment of monocytes into both progressing and regressing lesions of atherosclerosis. Importantly, some of the mechanisms revealed by mouse models are now being studied in human subjects. This Perspective highlights new mechanistic findings based on mouse models of diabetes-exacerbated atherosclerosis and discusses the relevance to humans and areas in which more research is urgently needed in order to lessen the burden of macrovascular complications of type 1 and type 2 diabetes mellitus.

We measured the health-related quality of life (HRQL) of diabetes mellitus patients using the Japanese version of EQ-5D, and examined the relationship between clinical condition and health status. A study was conducted on 220 patients with type 2 diabetes mellitus at a hospital in Saitama Prefecture on the day of their visit from November 17 to December 24, 1998. Patients evaluated their health status using five dimensions (5D) and a visual analog scale (VAS). The EQ-5D score was calculated based on the 5D responses using the Japanese version of the value set. There were no responses of "extreme problem." The frequency of "some problem" was significantly higher in patients with complications than in those without for mobility (27.4% and 14.4%) and anxiety/depression (25.7% and 13.5%). The mean EQ-5D score was 0.846 (95% confidence interval [CI] 0.817-0.874) in patients with complications versus 0.884 (95% CI 0.855-0.914) in those without complications. There was no statistically significant difference between VAS scores according to the presence or absence of diabetic complications, but a significant difference in VAS scores was seen according to the presence or absence of retinopathy. These findings suggest the value of measuring health status in diabetes mellitus patients, because it is able to comprehensively evaluate the patient's health condition, and add another dimension to the subjective symptoms and laboratory data.

Insulin therapy is often required to achieve good glycemic control for the patients with type 2 diabetes mellitus (T2DM), while protraction of glycemic control without insulin therapy may be preferable for patients. To determine the characteristics of and therapeutic regimen in outpatients with T2DM who were able to stop insulin therapy with satisfactory glycemic control in a real clinical practice setting in Japan by a case-control study. The present study was performed on 928 patients with T2DM who started insulin therapy in 2007. Data regarding age, sex, body mass index, duration of diabetes, HbA1c, postprandial plasma glucose, plasma fasting C-peptide immunoreactivity and treatment modality were compared between patients who were able to stop insulin therapy and those who continued with insulin. Of the 928 patients, 37 had stopped insulin therapy within 1 year. In the patients who stopped insulin therapy, the duration of diabetes was significantly shorter and the daily insulin dosage at initiation and the prevalence of sulfonylurea pretreatment significantly lower compared with patients who continued on insulin. In conclusion, almost 4% of T2DM patients were able to stop insulin therapy with satisfactory glycemic control in a real clinical practice setting in Japan. Shorter duration of diabetes and disuse of sulfonylureas prior to insulin may associate with stopping insulin therapy as a near-normoglycemic remission in outpatients with T2DM in Japan.

Functional foods are the most natural and safest source of health ingredients, providing health benefits beyond basic nutrition, and hence can be used as supplements for the prevention of secondary complications in diabetes. Persistent diabetes may cause glycation of various tissue proteins such as of those in lens, kidney, blood, and brain, which may further lead to the development of pathological conditions such as cataract and cardiovascular diseases. This study on adult rats was designed to assess if the functional food supplements A and B (proprietary blends of antioxidant rich plant materials) can reduce secondary complications such as cataract, dyslipidemia, and oxidative stress under severe diabetic conditions. After nine weeks of intervention of the supplements, it was found that the % HbA1c levels in the formulation group B significantly (p < 0.05) lowered (10.9%) followed by those in group A (11.1%) as compared to those in the diabetic fructose control (DFC) group (15.1%); moreover, plasma insulin levels were significantly (p < 0.01) improved in the formulation B group (9.8 mU L -1 ) as compared to those in the DFC group (8.5 mU L -1 ). The significantly higher level of plasma TEAC in group B (27.5 mg dL -1 ) (p < 0.02) and group A (26.6 mg dL -1 ) (p < 0.05) indicates an improved plasma antioxidants status as compared to that in DFC group (21.7 mg dL -1 ). Both the formulation groups A and B showed a decrease in AGEs and tryptophan fluorescence, which suggests amelioration of the glycation of lens proteins as compared to that in the DFC group. The present results indicate that the formulations A and B exhibit antiglycating and antioxidant potentials by inhibiting the high fructose-induced glycation in diabetic rats; hence, they may have therapeutic value as functional foods in the effective management of secondary complications associated with severe diabetic conditions.

SGLT2 inhibitors provide an effective therapeutic option for diabetes complicated with insulin antibodies.

Diabetes mellitus complicated with insulin antibodies is rare in clinical practice but usually difficult to control. A high amount of insulin antibodies, especially with low affinity and high binding capacity, leads to unstable glycemic control characterized by hyperglycemia unresponsive to large volume of insulin and unanticipated hypoglycemia. There are several treatment options, such as changing insulin preparation, immunosupression with glucocorticoids, and plasmapheresis, most of which are of limited efficacy. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a novel class of drug which decrease renal glucose reabsorption and lowers plasma glucose level independent of insulin action. We report here a case with diabetes complicated with insulin antibodies who was effectively controlled by an SGLT2 inhibitor. A 47-year-old man with type 2 diabetes treated with insulin had very poor glycemic control characterized by postprandial hyperglycemia unresponsive to insulin therapy and repetitive hypoglycemia due to insulin antibodies. Treatment with ipragliflozin, an SGLT2 inhibitor, improved HbA1c from 8.4% to 6.0% and glycated albumin from 29.4% to 17.9%. Continuous glucose monitoring revealed improvement of glycemic profile (average glucose level from 212 mg/dL to 99 mg/dL and glycemic standard deviation from 92 mg/dL to 14 mg/dL) with disappearance of hypoglycemic events. This treatment further ameliorated the characteristics of insulin antibodies and resulted in reduced insulin requirement. SGLT2 inhibitors may offer an effective treatment option for managing the poor glycemic control in diabetes complicated with insulin antibodies.

Diabetic foot, one of the most common and debilitating manifestations of type 2 diabetes mellitus (T2DM), is the leading cause of worldwide non-traumatic lower extremity amputations. Diabetics who are at risk of ulceration are currently mainly identified by a thorough clinical examination of the feet, which typically does not show clear symptoms during the early stages of disease progression. In this study, we used a non-linear dynamics tool, gait entropy (GaitEN), in addition to traditional linear gait analysis methods, to investigate gait alterations amongst diabetic patients with combinations of three types of T2DM related complications: retinopathy, diabetic peripheral neuropathy (DPN) and nephropathy. Peak plantar pressure (PPP) was not significantly different in the group with DPN as compared to the control group (diabetics with no complications, CONT) in the forefoot region (DPN: mean±SD: 396±69.4kPa, CONT: 409±68.9kPa), although it was significantly lower in the heel region (DPN: mean±SD: 285±43.1.4kPa, CONT: 295±61.8kPa). On the other hand, gait entropy was significantly lower for the DPN compared to CONT group (DPN: 0.95±0.34, CONT: 1.03±0.28, p<0.05). The significant low entropy was maintained when neuropathy was combined with either retinopathy or nephropathy. For the group with all three complications (ALL-C), the entropy was higher than CONT (ALL-C: 1.07±0.26). This may indicate an intrinsic sensorimotor feedback mechanism for the DPN patients to regulate their gait. However, this feedback gets weaker as patients develop multiple complications. Further analysis with longer walking time and different speeds is needed to verify the entropy results. Copyright © 2017 Elsevier B.V. All rights reserved.

[Low-dose aspirin in patients with diabete melitus: risks and benefits regarding macro and microvascular complications].

Aspirin is recommended as cardiovascular disease prevention in patients with diabetes mellitus. Due to the increased risk of bleeding and because of the hypothesis that there could be a worsening of microvascular complications related to aspirin, there has been observed an important underutilization of the drug. However, it is now known that aspirin is not associated with a deleterious effect on diabetic retinopathy and there is evidence indicating that it also does not affect renal function with usual doses (150 mg/d). On the other hand, higher doses may prove necessary, since recent data suggest that diabetic patients present the so called "aspirin resistance". The mechanisms of this resistance are not yet fully understood, being probably related to an abnormal intrinsic platelet activity. The employment of alternative antiplatelet strategies or the administration of higher aspirin doses (150-300 mg/d) should be better evaluated regarding effective cardiovascular disease prevention in diabetes as well as the possible effects on microvascular complications.

Adipose tissue, an endocrine organ of the body, is involved in some obesity-related disease states such as insulin resistance, diabetes mellitus, and atherosclerosis. Vaspin is a novel adipocyte with insulin sensitizing effects. In this study, we planned to estimate serum vaspin concentrations as related to glycemic status and the presence of macrovascular complications among elderly patients with type-2 diabetes mellitus (T2DM). A total of 230 elderly patients with T2DM were evaluated. These patients were divided into two groups: patients without complications (T2DM group, n = 110), and patients with macrovascular complications (T2DM + MC group, n = 120). In addition, 60 healthy elderly subjects were enrolled and assigned into the control group (NC group). Relevant parameters were matched for age and gender ratio. Serum vaspin concentrations were measured by Enzyme-linked immunosorbent assay (ELISA). Anthropometric measurements, plasma glucose and HbA 1C levels, insulin concentration, liver and kidney functions, and lipid profile were measured for each participant. Serum vaspin concentrations were significantly higher in the T2DM group than in the T2DM + MC group (F = 13.122, P < 0.01). These concentrations were also significantly higher among females, compared to males (T = 3.567, P < 0.05). Logistic regression analysis revealed that serum vaspin concentration, systolic blood pressure, HDL-C and T2DM duration were independent influencing factors for diabetic macrovascular complications. Serum vaspin may be considered as a potential marker to assess the status of elderly patients with T2DM and the risk of developing serious macrovascular complications. Further prospective studies are warranted. ChiCTR-OPC-14005698 , retrospectively registered on 20 Dec. 2014.

Risk scoring methods are effective for identifying persons at high risk of Type 2 diabetes mellitus, but such approaches have not yet been established in Japan. A total of 1935 subjects of a derivation cohort were followed up for 14 years from 1988 and 1147 subjects of a validation cohort independent of the derivation cohort were followed up for 5 years from 2002. Risk scores were estimated based on the coefficients (β) of Cox proportional hazards model in the derivation cohort and were verified in the validation cohort. In the derivation cohort, the non-invasive risk model was established using significant risk factors; namely, age, sex, family history of diabetes, abdominal circumference, body mass index, hypertension, regular exercise and current smoking. We also created another scoring risk model by adding fasting plasma glucose levels to the non-invasive model (plus-fasting plasma glucose model). The area under the curve of the non-invasive model was 0.700 and it increased significantly to 0.772 (P < 0.001) in the plus-fasting plasma glucose model. The ability of the non-invasive model to predict Type 2 diabetes was comparable with that of impaired glucose tolerance, and the plus-fasting plasma glucose model was superior to it. The cumulative incidence of Type 2 diabetes was significantly increased with elevating quintiles of the sum scores of both models in the validation cohort (P for trend < 0.001). We developed two practical risk score models for easily identifying individuals at high risk of incident Type 2 diabetes without an oral glucose tolerance test in the Japanese population. © 2011 The Authors.

To report the incidence, etiology, and treatments of diabetes insipidus-like state that complicate percutaneous transluminal renal stenting (PTRS) for transplant renal artery stenosis (TRAS). Data from 7 patients on whom PTRS for TRAS was performed between October 2008 and March 2012 were reviewed retrospectively. The parameters investigated included blood flow velocity, blood pressure, and creatinine levels before and after the intervention. The procedural success rate was 100%. Three cases developed a diabetes insipidus-like state in the immediate postprocedural period. Urine output returned to normal within 2 weeks after treatment. The median blood flow velocity was significantly reduced from 4.51 m/sec (4.31-4.61 m/sec) at the time of TRAS diagnosis to 1.33 m/sec (1.31-1.51 m/sec) at the most recent follow-up of the group with a diabetes insipidus-like state. The ratio of median blood flow velocity before and after stenting in the group with a diabetes insipidus-like state was significantly higher than that in the group without a diabetes insipidus-like state (3.39 vs. 1.93). Diabetes insipidus-like state that complicates PTRS for TRAS is not an uncommon event, but appears to be underreported in the medical literature. A high ratio of pre- and poststenting median blood flow velocity may be a predictor for a postprocedural diabetes insipidus-like state. The most probable cause may be the marked increase in renal arterial flow. Early recognition of the condition is essential to avoid dehydration and electrolyte imbalance.

Complications and inferior outcomes of fractures in the setting of diabetes mellitus (DM) are well documented. The incidence of DM is increasing rapidly, particularly in an aging and obese population. Thus, the combination of DM and fracture is becoming a serious health problem worldwide. As many fractures are relatively uncomplicated in the healthy patient population, a concerted effort to improve outcomes of fractures in patients with DM is warranted. In this article, we review relevant studies and examine the pathobiological mechanisms influencing fracture outcomes, including complications related to bone and soft-tissue healing, and infection.

Previous studies have related poor glycemic control and/or some diabetes complications to low socioeconomic status. Some aspects of socioeconomic status have not been assessed in these studies. In the present study, we used an individual index of deprivation, the Evaluation de la Précarité et des Inégalités de santé dans les Centres d'Examens de Santé (Evaluation of Precarity and Inequalities in Health Examination Centers [EPICES]) score, to determine the relationship among glycemic control, diabetes complications, and individual conditions of deprivation. We conducted a cross-sectional prevalence study in 135 consecutive diabetic patients (age 59.41 +/- 13.2 years [mean +/- SD]) admitted in the hospitalization unit of a French endocrine department. Individual deprivation was assessed by the EPICES score, calculated from 11 socioeconomic questions. Glycemic control, lipid levels, blood pressure, retinopathy, neuropathy, and nephropathy were assessed. HbA(1c) level was significantly correlated with the EPICES score (r = 0.366, P < 0.001). The more deprived patients were more likely than the less deprived patients to have poor glycemic control (beta = 1.984 [SE 0.477], P < 0.001), neuropathy (odds ratio 2.39 [95% CI 1.05-5.43], P = 0.037), retinopathy (3.66 [1.39-9.64], P = 0.009), and being less often admitted for 1-day hospitalization (0.32 [0.14-0.74], P = 0.008). No significant relationship was observed with either nephropathy or cardiovascular risk factors. Deprivation status is associated with poor metabolic control and more frequent microvascular complications, i.e., retinopathy and neuropathy. The medical and economic burden of deprived patients is high.

The incidence of type 1 diabetes complications appears to be decreasing, but relative contributions of risk factors are unclear. We thus estimated the effect of modifiable risk factors on the incidence of a composite end point, major outcomes of diabetes (MOD). The Pittsburgh Epidemiology of Diabetes Complications (EDC) Study was used to derive two cohorts based on diabetes diagnosis year (1960-1969 and 1970-1980). Baseline exam data in the current analysis for the 1960s group were collected in 1986-1988 and for the 1970s in 1996-1998. Each group was followed for 8 years for MOD incidence (diabetes-related death, myocardial infarction, revascularization procedure/blockage ≥50%, stroke, end-stage renal disease, blindness, and amputation). Assessed risk factors include the following: HbA1c, hypertension, microalbuminuria, BMI, hypercholesterolemia, and smoking. Accelerated failure time models were used to estimate the acceleration factor. MOD incidence decreased in the 1970s cohort (15.8% [95% CI 11.6-21.4]) compared with the 1960s (22.6% [17.0-29.1]) over the 8-year follow-up (P = 0.06). Hypertension and microalbuminuria were associated with significantly accelerated MOD incidence in both cohorts (P < 0.01 for both). High HbA1c (P = 0.0005), hypercholesterolemia (P = 0.01), and current smoking (P = 0.003) significantly accelerated the incidence of MOD in the 1960s but not 1970s cohort. BMI was not associated with MOD in either cohort. These results suggest that hypertension and microalbuminuria remain important predictors of complications that are not being adequately addressed.

Objective To assess the sociodemographic patterning of changes in glycaemic control of patients with diabetes affected by the 2011 triple disaster in Japan (earthquake, tsunami and nuclear accident). Methods A retrospective cohort study was undertaken with 404 patients with diabetes at a public hospital in Minamisoma City, Fukushima Prefecture. Glycated haemoglobin (HbA1c) levels were measured in 2010, 2011 and 2012 to capture changes in glycaemic control postdisaster. Age, sex, urban/rural residency, evacuation status and medication use were also assessed. Results There was an overall deterioration in glycaemic control after the disaster, with the mean HbA1c rising from 6.77% in 2010 to 6.90% in 2012 (National Glycohemoglobin Standardization Program, NGSP). Rural residency was associated with a lower likelihood of deteriorating control (OR 0.34, 95% CI 0.13 to 0.84), compared with urban residency. Older age (OR 0.95, 95% CI 0.91 to 0.98) was also slightly protective against increased HbA1c. Evacuation and sex were not significant predictors. Conclusions Patients with diabetes who were affected by Japan's triple disaster experienced a deterioration in their glycaemic control following the disasters. The extent of this deterioration was mediated by sociodemographic factors, with rural residence and older age protective against the effects of the disaster on glycaemic control. These results may be indicative of underlying social determinants of health in rural Japan. PMID:27388360

To investigate the mechanism of diabetes insipidus complicated with skeletal fluorosis and the surgical treatment of spinal canal stenosis caused by skeletal fluorosis. From January 2000 to November 2011, 5 patients with diabetes insipidus complicated with skeletal fluorosis were treated with drug and cervical or thoracic posterior decompression including 2 males and 3 females with age of 35, 45, 47, 49, 55 years old respectively. The symptoms was mainly limb motor sensory disturbance accompanied by polyuria and polyuria. Imaging showed that cervical and thoracic multi-segmental continuous spinal stenosis. It was diagnosed with diabetes insipidus according to the symptoms and laboratory tests. According to the symptoms, the vertebral with problems were located and treated by posterior laminectomy decompression or the expansive open-door laminectomy. The recovery of neurological symptoms were recorded and the operation result were evaluate by JOA score improvement rate. The wound healed well in 5 cases, and 1 case of cervical axial pain was improved after symptomatic treatment. Five patients were followed up for 2 to 6 years with an average of 4 years. Numbness of limb and weakness symptoms of follow-up patients were significantly improved, muscle strength and acupuncture hypothyroidism were significantly improved compared with preoperative, the JOA score was significantly improved. At the final follow-up, the improvement rate got excellent results in 2 cases, good in 2 and fair in 1. Long-term high intake of fluoride can cause skeletal fluorosis in patients with diabetes insipidus. The posterior decompression is effective for the majority of spinal canal stenosis caused by skeletal fluorosis.

The aim of this study was to assess the efficacy of glyburide in the treatment of gestational diabetes mellitus and to compare the maternal and fetal outcome between two groups treated either with insulin or glyburide. Women with gestational diabetes not responding to diet control were randomized into two groups: (i) the control group receiving insulin (n = 32); and (ii) the study group receiving glyburide (n = 32). Primary outcome was assessed in terms of achievement of glycemic control and secondary outcome was assessed by the incidence of maternal and fetal complications in the insulin and glyburide treated groups. The achievement of glycemic control between the insulin and the glyburide treated groups showed no significant difference (97.1%, 93.8%). The occurrence of maternal complications (P = 0.87) and fetal complications (P = 0.32) were comparable between the insulin and glyburide treated groups. Glyburide was found to be as efficacious as insulin in achieving euglycemia in the treatment of gestational diabetic women who require treatment beyond diet control. © 2013 The Authors.

Microvascular function in patients with type 1 diabetes without chronic complications was assessed using skin capillary recruitment during post-occlusive reactive hyperemia (PORH). Structural (maximal) capillary density was evaluated during venous occlusion. The study included 48 consecutive outpatients aged 26.3 ± 10.8 years with type 1 diabetes (duration of 9.5 years) without chronic complications and 34 control subjects. Intravital capillary video-microscopy was used in the dynamic study of skin capillaries in the dorsum of the fingers and toes. Capillary recruitment during PORH (% increase in mean capillary density, MCD) was significantly higher in the controls than the patients in both the fingers (p < 0.001) and toes (p < 0.001). During venous occlusion, MCD increase was also higher in the controls than the patients in both the fingers (p < 0.05) and toes (p < 0.0001). In patients, no difference was found between MCD at baseline and after venous occlusion in the fingers but a decrease was observed in the toes (p < 0.001). It is concluded that skin capillary function is significantly impaired in both fingers and toes of patients with type 1 diabetes without chronic complications. Moreover, capillary density during venous occlusion did not increase in either extremity in the patients, suggesting that their capillaries at rest are already maximally recruited. PMID:17823692

Role of Superoxide Dismutase 2 Gene Ala16Val Polymorphism and Total Antioxidant Capacity in Diabetes and its Complications

Diabetes Mellitus (DM) is a chronic heterogeneous disorder and oxidative stress is a key participant in the development and progression of it and its complications. Anti-oxidant status can affect vulnerability to oxidative damage, onset and progression of diabetes and diabetes complications. Superoxide dismutase 2 (SOD2) is one of the major antioxidant defense systems against free radicals. SOD2 is encoded by the nuclear SOD2 gene located on the human chromosome 6q25 and the Ala16Val polymorphism has been identified in exon 2 of the human SOD2 gene. Ala16Val (rs4880) is the most commonly studied SOD2 single nucleotide polymorphism (SNP) in SOD2 gene. This SNP changes the amino acid at position 16 from valine (Val) to alanine (Ala), which has been shown to cause a conformational change in the target sequence of manganese superoxide dismutase (MnSOD) and also affects MnSOD activity in mitochondria. Ala16Val SNP and changes in the activity of the SOD2 antioxidant enzyme have been associated with altered progression and risk of different diseases. Association of this SNP with diabetes and some of its complications have been studied in numerous studies. This review evaluated how rs4880, oxidative stress and antioxidant status are associated with diabetes and its complications although some aspects of this line still remain unclear. PMID:27141263

Experimental evidence for curcumin and its analogs for management of diabetes mellitus and its associated complications.

Diabetes mellitus is a serious world health problem and one of the most studied diseases; a major concern about its treatment is that β-cell mass and functionality is hard to restore. In addition, it is frequently associated with severe complications, such as diabetic nephropathy and cardiomyopathy. The anti-inflammatory, anti-oxidative and anti-apoptotic properties of curcumin have made it a promising molecule for the treatment of this pathology; however, its solubility and bioavailability problems are still the subject of multiple studies. To cope with those difficulties, several approaches have been evaluated, such as the development of pharmaceutical formulations and curcumin analogs. This review discusses some of the studied therapeutic targets for curcumin in diabetes as well as the structural characteristics and targets of its analogs. The shortening of the central seven-carbon chain of curcumin has given rise to compounds without glucose-lowering effects but potentially useful for the treatment of diabetes complications; whereas preserving this chain retains the glucose-lowering properties. Most of the analogs discussed here have been recently synthesized and tested in animal models of type 1 diabetes; more studies in models of type 2 diabetes are needed. Copyright © 2015 Elsevier B.V.

Sex and Gender Differences in Risk, Pathophysiology and Complications of Type 2 Diabetes Mellitus.

2016-06-01

The steep rise of type 2 diabetes mellitus (T2DM) and associated complications go along with mounting evidence of clinically important sex and gender differences. T2DM is more frequently diagnosed at lower age and body mass index in men; however, the most prominent risk factor, which is obesity, is more common in women. Generally, large sex-ratio differences across countries are observed. Diversities in biology, culture, lifestyle, environment, and socioeconomic status impact differences between males and females in predisposition, development, and clinical presentation. Genetic effects and epigenetic mechanisms, nutritional factors and sedentary lifestyle affect risk and complications differently in both sexes. Furthermore, sex hormones have a great impact on energy metabolism, body composition, vascular function, and inflammatory responses. Thus, endocrine imbalances relate to unfavorable cardiometabolic traits, observable in women with androgen excess or men with hypogonadism. Both biological and psychosocial factors are responsible for sex and gender differences in diabetes risk and outcome. Overall, psychosocial stress appears to have greater impact on women rather than on men. In addition, women have greater increases of cardiovascular risk, myocardial infarction, and stroke mortality than men, compared with nondiabetic subjects. However, when dialysis therapy is initiated, mortality is comparable in both males and females. Diabetes appears to attenuate the protective effect of the female sex in the development of cardiac diseases and nephropathy. Endocrine and behavioral factors are involved in gender inequalities and affect the outcome. More research regarding sex-dimorphic pathophysiological mechanisms of T2DM and its complications could contribute to more personalized diabetes care in the future and would thus promote more awareness in terms of sex- and gender-specific risk factors.

Background Diabetes imposes a substantial burden globally in terms of premature mortality, morbidity, and health care costs. Estimates of economic outcomes associated with diabetes are essential inputs to policy analyses aimed at prevention and treatment of diabetes. Our objective was to estimate and compare event rates, hospital utilization, and costs associated with major diabetes-related complications in high-, middle-, and low-income countries. Methods and Findings Incidence and history of diabetes-related complications, hospital admissions, and length of stay were recorded in 11,140 patients with type 2 diabetes participating in the Action in Diabetes and Vascular Disease (ADVANCE) study (mean age at entry 66 y). The probability of hospital utilization and number of days in hospital for major events associated with coronary disease, cerebrovascular disease, congestive heart failure, peripheral vascular disease, and nephropathy were estimated for three regions (Asia, Eastern Europe, and Established Market Economies) using multiple regression analysis. The resulting estimates of days spent in hospital were multiplied by regional estimates of the costs per hospital bed-day from the World Health Organization to compute annual acute and long-term costs associated with the different types of complications. To assist, comparability, costs are reported in international dollars (Int$), which represent a hypothetical currency that allows for the same quantities of goods or services to be purchased regardless of country, standardized on purchasing power in the United States. A cost calculator accompanying this paper enables the estimation of costs for individual countries and translation of these costs into local currency units. The probability of attending a hospital following an event was highest for heart failure (93%–96% across regions) and lowest for nephropathy (15%–26%). The average numbers of days in hospital given at least one admission were greatest for

Diabetic nephropathy is a serious complication in patients with type 2 diabetes. The aim of this study was to explore the factors associated with the progression of this complication in elderly patients with type 2 diabetes. This retrospective study of a subgroup of patients registered with the Japanese Elderly Diabetes Intervention Trial included 621 Japanese patients with type 2 diabetes mellitus (age ≥ 65 years, 346 with normoalbuminuria, 190 with microalbuminuria and 85 with overt proteinuria). Multivariate Cox proportional hazard regression model with a backward stepwise procedure was applied to select factors with significant effects on worsening of nephropathy stage and the doubling of serum creatinine. During the follow up (median 52 months), 21% of patients progressed from normoalbuminuria and microalbuminuria to a worse nephropathy stage. Aging, female sex and high-density lipoprotein cholesterol were identified as independent and significant factors that worsen nephropathy stage. Also, 6.1% of patients showed doubling of serum creatinine during follow up. A positive history of cardiovascular disease, hyperuricemia and conventional therapy were identified as significant factors involved in the doubling of serum creatinine. The cumulative incidence of the doubling of serum creatinine was significantly lower in the intensive therapy group than the conventional therapy group (P = 0.016), although that of progression of nephropathy stage was similar in the two groups. We identified several factors associated with the progression of diabetic nephropathy in elderly patients with type 2 diabetes. The results suggest that multiple risk factor intervention seems important in preventing deterioration of renal dysfunction. © 2012 Japan Geriatrics Society.

Endothelial dysfunction is a central pathomechanism in diabetes-associated complications. We hypothesized a pathogenic role in this dysfunction of cathepsin S (Cat-S), a cysteine protease that degrades elastic fibers and activates the protease-activated receptor-2 (PAR2) on endothelial cells. We found that injection of mice with recombinant Cat-S induced albuminuria and glomerular endothelial cell injury in a PAR2-dependent manner. In vivo microscopy confirmed a role for intrinsic Cat-S/PAR2 in ischemia–induced microvascular permeability. In vitro transcriptome analysis and experiments using siRNA or specific Cat-S and PAR2 antagonists revealed that Cat-S specifically impaired the integrity and barrier function of glomerular endothelial cells selectively through PAR2. In human and mouse type 2 diabetic nephropathy, only CD68+ intrarenal monocytes expressed Cat-S mRNA, whereas Cat-S protein was present along endothelial cells and inside proximal tubular epithelial cells also. In contrast, the cysteine protease inhibitor cystatin C was expressed only in tubules. Delayed treatment of type 2 diabetic db/db mice with Cat-S or PAR2 inhibitors attenuated albuminuria and glomerulosclerosis (indicators of diabetic nephropathy) and attenuated albumin leakage into the retina and other structural markers of diabetic retinopathy. These data identify Cat-S as a monocyte/macrophage–derived circulating PAR2 agonist and mediator of endothelial dysfunction–related microvascular diabetes complications. Thus, Cat-S or PAR2 inhibition might be a novel strategy to prevent microvascular disease in diabetes and other diseases. PMID:26567242

Diabetes is one of the top priorities in medical science and health care management, and an abundance of data and information is available on these patients. Whether data stem from statistical models or complex pattern recognition models, they may be fused into predictive models that combine patient information and prognostic outcome results. Such knowledge could be used in clinical decision support, disease surveillance, and public health management to improve patient care. Our aim was to review the literature and give an introduction to predictive models in screening for and the management of prevalent short- and long-term complications in diabetes. Predictive models have been developed for management of diabetes and its complications, and the number of publications on such models has been growing over the past decade. Often multiple logistic or a similar linear regression is used for prediction model development, possibly owing to its transparent functionality. Ultimately, for prediction models to prove useful, they must demonstrate impact, namely, their use must generate better patient outcomes. Although extensive effort has been put in to building these predictive models, there is a remarkable scarcity of impact studies. © 2015 Diabetes Technology Society.

Hyperketonemia and ketosis increase the risk of complications in type 1 diabetes

PubMed Central

2016-01-01

Diets that boost ketone production are increasingly used for treating several neurological disorders. Elevation in ketones in most cases is considered favorable, as they provide energy and are efficient in fueling the body’s energy needs. Despite all the benefits from ketones, the above normal elevation in the concentration of ketones in the circulation tend to illicit various pathological complications by activating injurious pathways leading to cellular damage. Recent literature demonstrates a plausible link between elevated levels of circulating ketones and oxidative stress, linking hyperketonemia to innumerable morbid conditions. Ketone bodies are produced by the oxidation of fatty acids in the liver as a source of alternative energy that generally occurs in glucose limiting conditions. Regulation of ketogenesis and ketolysis plays an important role in dictating ketone concentrations in the blood. Hyperketonemia is a condition with elevated blood levels of acetoacetate (AA), 3-β-hydroxybutyrate (BHB), and acetone. Several physiological and pathological triggers, such as fasting, ketogenic diet, and diabetes cause an accumulation and elevation of circulating ketones. Complications of the brain, kidney, liver, and microvasculature were found to be elevated in diabetic patients who had elevated ketones compared to those diabetics with normal ketone levels. This review summarizes the mechanisms by which hyperketonemia and ketoacidosis cause an increase in redox imbalance and thereby increasing the risk of morbidity and mortality in patients.

The aim of this study was to develop a discrete-time simulation model for people with type 1 diabetes mellitus, to estimate and compare mean life expectancy and quality-adjusted life-years (QALYs) over a lifetime between intensive and conventional blood glucose treatment groups. We synthesized evidence on type 1 diabetes patients using several published sources. The simulation model was based on 13 equations to estimate risks of events and mortality. Cardiovascular disease (CVD) risk was obtained from results of the DCCT (diabetes control and complications trial). Mortality post-CVD event was based on a study using linked administrative data on people with diabetes from Western Australia. Information on incidence of renal disease and the progression to CVD was obtained from studies in Finland and Italy. Lower-extremity amputation (LEA) risk was based on the type 1 diabetes Swedish inpatient registry, and the risk of blindness was obtained from results of a German-based study. Where diabetes-specific data were unavailable, information from other populations was used. We examine the degree and source of parameter uncertainty and illustrate an application of the model in estimating lifetime outcomes of using intensive and conventional treatments for blood glucose control. From 15 years of age, male and female patients had an estimated life expectancy of 47.2 (95 % CI 35.2-59.2) and 52.7 (95 % CI 41.7-63.6) years in the intensive treatment group. The model produced estimates of the lifetime benefits of intensive treatment for blood glucose from the DCCT of 4.0 (95 % CI 1.2-6.8) QALYs for women and 4.6 (95 % CI 2.7-6.9) QALYs for men. Absolute risk per 1,000 person-years for fatal CVD events was simulated to be 1.37 and 2.51 in intensive and conventional treatment groups, respectively. The model incorporates diabetic complications risk data from a type 1 diabetes population and synthesizes other type 1-specific data to estimate long-term outcomes of CVD, end-stage renal

Chrysin (CH) is a natural flavonoid with pharmacological influences. The purpose of the current study was the assessment of possible protective effects of CH against oxidative damage in the serum, liver, brain, and pancreas of streptozotocin (STZ)- induced diabetic rats. In the present study, the rats were divided into the following groups of 8 animals each: control, untreated diabetic, 3 CH (20, 40, 80 mg/kg/day)-treated diabetic groups. To find out the modulations of cellular antioxidant defense systems, malondialdehyde (MDA) level and antioxidant enzymes including glutathione-S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT) activities were determined in the serum, liver, brain, and pancreas. STZ caused an elevation of glucose, MDA, TG, TC, LDL-C and with reduction of HDL-C, total protein, SOD, CAT, and GST in the serum, liver, brain, and pancreas (p < 0.01). The findings showed that the significant elevation in the glucose, MDA, TG, TC, LDL-C and reduction of HDL-C, total protein, SOD, CAT, and GST were ameliorated in the CH-treated diabetic groups versus to the untreated groups, in a dose dependent manner (p < 0.05). The current study offers that CH may be recovered diabetes and its complications by modification of oxidative stress.

As skin autofluorescence (AF) can assess subcutaneous accumulation of fluorescent advanced glycation end-products (AGEs), this study aimed to investigate whether it was linked to glycaemic control and complications in patients with type 1 diabetes mellitus (T1DM). Using the AGE Reader™, AF was measured in T1DM patients referred to Haut-Levêque Hospital (Bordeaux, France); data on their HbA1c levels measured every 6months as far back as the last 5years were also collected. The association of AF with the patients' past glucose control, based on their latest HbA1c values, and the means of the last five and 10 HbA1c values, and with diabetic complications was also examined by linear regression analysis. The sample included 300 patients: 58% were male; the mean age was 49 (SD 17) years and the mean diabetes duration was 21 (SD 13) years. The median skin AF measurement was 2.0 [25th-75th percentiles: 1.7-2.4] arbitrary units (AU), and this was associated with age (β=0.15 per 10years, P<0.001) and diabetes duration (β=0.17 per 10years, P<0.001). After adjusting for age and estimated glomerular filtration rate (eGFR), the skin AF measurement was also related to the means of the last five and 10 HbA1c values (β=0.10 per 1% of HbA1c, P=0.005, and β=0.13 per 1% of HbA1c, P=0.001, respectively). In addition, the skin AF was associated with retinopathy (P<0.001), albuminuria (P<0.001) and decreased eGFR (P<0.001). In conclusion, the skin AF is related to the long-term glucose control and diabetic complications. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

OBJECTIVE To investigate the relationship between fasting insulin levels and metabolic risk factors (MRFs) in type 2 diabetic patients at the first clinic/hospital visit in Japan over the years 2000 to 2009. RESEARCH DESIGN AND METHODS In total, 4,798 drug-naive Japanese patients with type 2 diabetes were registered on their first clinic/hospital visits. Conventional clinical factors and fasting insulin levels were observed at baseline within the Japan Diabetes Clinical Data Management (JDDM) study between consecutive 2-year groups. Multiple linear regression analysis was performed using a model in which the dependent variable was fasting insulin values using various clinical explanatory variables. RESULTS Fasting insulin levels were found to be decreasing from 2000 to 2009. Multiple linear regression analysis with the fasting insulin levels as the dependent variable showed that waist circumference (WC), BMI, mean blood pressure, triglycerides, and HDL cholesterol were significant, with WC and BMI as the main factors. ANCOVA after adjustment for age and fasting plasma glucose clearly shows the decreasing trend in fasting insulin levels and the increasing trend in BMI. CONCLUSIONS During the 10-year observation period, the decreasing trend in fasting insulin was related to the slight increase in WC/BMI in type 2 diabetes. Low pancreatic β-cell reserve on top of a lifestyle background might be dependent on an increase in MRFs. PMID:22665215

The formation of Maillard products is increased in the diabetes mellitus. These advanced glycated end products (AGEs) alter metabolic functions of macromolecules and increase free radical formation while decreasing free radical-scavenging enzyme activity. The elimination of AGEs is insured by the macrophage cells equipped with appropriate receptors (RAGE) and cleared by kidneys. The knowledge of these molecular mechanisms had allowed the emergence of biochemical analytes such as 3-deoxyglucosone, pentosidine, and carboxymethyl-lysine, as markers of the ris of micro- and macro-angiopathy, the main chronic complications of the diabetes mellitus.

To identify the principal sociodemographic, clinical, and behavioral characteristics of patients participating in diabetic care programs in the city of Medellín, Colombia, and to evaluate progress toward the goal of metabolic control and diabetic care standards. A cross-sectional, descriptive study was done, analyzing the clinical records of patients who had been participating for at least 6 months in the diabetic care programs of nine health care centers in Medellín. The study period ran from January 2001 to December 2003. The following data were collected: sociodemographic (age and sex), clinical (time since disease onset, diabetes type and treatment, and concurrent illnesses and their treatment), lifestyle habits (exercise routine, smoking, and sugar and fat consumption), chronic complications, and laboratory test results from the prior year. Questionable or missing data were categorized as unavailable. Of the 3 583 clinical histories evaluated, we were able to confirm the form of diabetes for 3 554 patients. Of those 3 554, 95.1% had type 2 diabetes. Overall, 56.9% (95% confidence interval (95% CI): 55.2% to 58.6%) of the patients exercised regularly, 15.1% (95% CI: 13.9% to 16.3%) were current smokers, 17.7% (95% CI: 16.4% to 19.0%) were former smokers, and 67.2% (95% CI: 65.6% to 68.8%) had never smoked. In all, 21.0% (95% CI: 19.6% to 22.5%) of the patients consumed sugar regularly, while 24.8% (95% CI: 23.3% to 26.3%) consumed fats and only 19.5% (95% CI: 17.8% to 21.3%) were self-monitoring their glucose levels at least weekly. Among the type 2 diabetics, 68.8% had high blood pressure, and 98.2% had dyslipidemia. The average body mass index was 28.0 kg/m(2) (95% CI: 27.8 to 28.2). The average number of medications that the patients were taking to treat type 2 diabetes was 1.3; to treat high blood pressure, 1.9; and to treat dyslipidemia, 0.6. There were no data on low-density lipoprotein (LDL) cholesterol in 44.8% of the clinical records, and no data on

Pharmacologic management of types 1 and 2 diabetes mellitus and their complications in women of childbearing age.

The numbers of women of childbearing age with pregestational diabetes mellitus (diabetes existing before pregnancy) are increasing, primarily because more patients are developing type 2 diabetes at younger ages. The teratogenicity associated with hyperglycemia in early pregnancy is well documented, and tight glucose control minimizes the risk of congenital malformation. Preconception planning is essential; thus contraception that does not worsen complications of diabetes is desirable. In addition, because contraceptives are not 100% effective, the treatment of elevated blood glucose levels, hypertension, and dyslipidemia in these women requires consideration of unplanned pregnancy. We summarized the literature to aid clinicians in choosing individualized treatment that minimizes risk in case pregnancy occurs and maximizes benefit in preventing the complications of diabetes. In women with well-controlled diabetes without vascular disease, all contraceptive methods are safe. Intrauterine devices are recommended due to their minimal effects on risk factors for diabetic complications and their lack of reliance on patient adherence for efficacy. Among insulins, the insulin analogs-insulin lispro, insulin aspart, and insulin detemir-offer patients greater convenience than regular insulin and NPH insulin, and they are safe in case of unplanned pregnancy. Of the noninsulin agents, glyburide and metformin are the safest during pregnancy, but many of the other agents pose minimal risk as long as they are withdrawn during early pregnancy. The risks and benefits of angiotensin-converting enzyme inhibitors in women with compelling indications must be weighed individually. In hypertensive patients at a high risk for unplanned pregnancy, nifedipine should be considered due to literature supporting its safety during early pregnancy. Pravastatin is recommended for women with dyslipidemia who are using effective contraception because there have been no reports of birth defects with

Role of antioxidants in redox regulation of diabetic cardiovascular complications.

Cardiovascular dysfunction is leading cause for the mortality of diabetic individuals, in part due to a specific cardiomyopathy, and due to altered endothelial dependent/independent vascular reactivity. Cardiovascular complications result from multiple parameters including glucotoxicity, lipotoxicity, fibrosis and mitochondrial uncoupling. Oxidative stress arises from an imbalance between the production of reactive oxygen and nitrogen species (ROS and RNS) and the capability of biological system to readily detoxify reactive intermediates. Several studies have reported beneficial effects of a therapy with antioxidant agents, including trace elements and other antioxidants, against the cardiovascular system dysfunction due to the diabetes. Antioxidants act through different mechanisms to prevent oxidant-induced cell damages acting either directly or indirectly. They can reduce the generation of ROS, scavenge ROS, or interfere with ROS-induced alterations. Modulating mitochondrial activity is an important possibility to control ROS production. Hence, the use of PPARα agonist to reduce fatty acid oxidation and of trace elements such as selenium as antioxidant and other antioxidants such as vitamins E and C, contribute to the prevention of diabetes-induced cardiovascular dysfunction. The paradigm that, inhibiting the overproduction of superoxides and peroxides would prevent cardiac dysfunction in diabetes has been difficult to verify using conventional antioxidants like vitamins E and C. That led to use of catalytic antioxidants such as SOD/CAT mimetics. Hence, well-tuned, balanced and responsive antioxidant defence systems are vital for proper prevention against diabetic damage. Myocardial cell death is observed in the hearts of diabetic patients and animal models; however, its importance in the development of diabetic cardiomyopathy is not completely understood. This review aims to summarize our present knowledge on various strategies to control oxidative stress and

To assess the sociodemographic patterning of changes in glycaemic control of patients with diabetes affected by the 2011 triple disaster in Japan (earthquake, tsunami and nuclear accident). A retrospective cohort study was undertaken with 404 patients with diabetes at a public hospital in Minamisoma City, Fukushima Prefecture. Glycated haemoglobin (HbA1c) levels were measured in 2010, 2011 and 2012 to capture changes in glycaemic control postdisaster. Age, sex, urban/rural residency, evacuation status and medication use were also assessed. There was an overall deterioration in glycaemic control after the disaster, with the mean HbA1c rising from 6.77% in 2010 to 6.90% in 2012 (National Glycohemoglobin Standardization Program, NGSP). Rural residency was associated with a lower likelihood of deteriorating control (OR 0.34, 95% CI 0.13 to 0.84), compared with urban residency. Older age (OR 0.95, 95% CI 0.91 to 0.98) was also slightly protective against increased HbA1c. Evacuation and sex were not significant predictors. Patients with diabetes who were affected by Japan's triple disaster experienced a deterioration in their glycaemic control following the disasters. The extent of this deterioration was mediated by sociodemographic factors, with rural residence and older age protective against the effects of the disaster on glycaemic control. These results may be indicative of underlying social determinants of health in rural Japan. Published by the BMJ Publishing Group Limited.

The role played by serine proteases in the development and worsening of vascular complications in type 1 diabetes mellitus.

Finotti, Paola

2006-08-01

Much attention has been given to the role played by serine proteases in the development and worsening of vascular complications in Type 1 diabetes mellitus. A generalized increase in proteolytic activity, either due to a true increase in concentration of specific proteases or defects of their protease inhibitors, represents an early marker of diabetes. However, the precise molecular mechanism whereby an unopposed proteolytic activity leads to overt vascular alterations has not fully been elucidated as yet. The picture is further complicated by the fact that, although sharing the same function, serine proteases constitute a structurally heterogeneous class of molecules. Besides classical proteases, for most part belonging to coagulative and fibrinolytic systems, other unrelated molecules exhibit serine-like protease activity and are capable of triggering both inflammatory and immune reactions. The specific role of these non classical serine proteases in the complex pathogenesis of diabetes and its vascular complications is attracting a new investigative interest, as these molecules may represent additional therapeutic targets. This review will focus on most recent acquisitions on this issue relevant to Type 1 diabetes.

Background Endometriosis, which occurs in approximately 10% of women of reproductive age, is defined as the presence of endometrial tissue outside the uterus. Women with endometriosis are more likely to have difficulty conceiving and tend to receive infertility treatment, including assisted reproductive technology (ART) therapy. There has not yet been a prospective cohort study examining the effects of endometriosis on pregnancy outcome in pregnant Japanese women. Methodology This was a prospective cohort study of the incidence of obstetrical complications in women with endometriosis using data of the Japan Environment & Children’s Study (JECS). Included in this study were 9,186 pregnant women in the JECS with or without a history of endometriosis who gave birth or stillbirth or whose pregnancy was terminated with abortion between February and December 2011. Main Outcome Measures The effects of endometriosis on pregnancy outcome. Results Of the 9,186 pregnant women in the JECS, 4,119 (44.8%) had obstetrical complications; 330 participants reported a diagnosis of endometriosis before pregnancy, and these women were at higher risk for complications of pregnancy than those without a history of endometriosis (odds ratio (OR) = 1.50; 95% confidence interval (CI) 1.20 to 1.87). Logistic regression analyses showed that the adjusted OR for obstetrical complications of pregnant women who conceived naturally and had a history of endometriosis was 1.45 (CI 1.11 to 1.90). Among pregnant women with endometriosis, the ORs of preterm premature rupture of the membranes (PROM) and placenta previa were significantly higher compared with women never diagnosed with endometriosis who conceived naturally or conceived after infertility treatment, except for ART therapy (OR 2.14, CI 1.03–4.45 and OR 3.37, CI 1.32–8.65). Conclusions This study showed that endometriosis significantly increased the incidence of preterm PROM and placenta previa after adjusting for confounding of the

Prolonged Effect of Intensive Therapy on the Risk of Retinopathy Complications in Patients With Type 1 Diabetes Mellitus

2009-01-01

Objective To examine the persistence of the original treatment effects 10 years after the Diabetes Control and Complications Trial (DCCT) in the follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) study. In the DCCT, intensive therapy aimed at near-normal glycemia reduced the risk of microvascular complications of type 1 diabetes mellitus compared with conventional therapy. Methods Retinopathy was evaluated by fundus photography in 1211 subjects at EDIC year 10. Further 3-step progression on the Early Treatment Diabetic Retinopathy Study scale from DCCT closeout was the primary outcome. Results After 10 years of EDIC follow-up, there was no significant difference in mean glycated hemoglobin levels (8.07% vs 7.98%) between the original treatment groups. Nevertheless, compared with the former conventional treatment group, the former intensive group had significantly lower incidences from DCCT close of further retinopathy progression and proliferative retinopathy or worse (hazard reductions, 53%-56%; P<.001). The risk (hazard) reductions at 10 years of EDIC were attenuated compared with the 70% to 71% over the first 4 years of EDIC (P<.001). The persistent beneficial effects of former intensive therapy were largely explained by the difference in glycated hemoglobin levels during DCCT. Conclusion The persistent difference in diabetic retinopathy between former intensive and conventional therapy (“metabolic memory”) continues for at least 10 years but may be waning. PMID:19064853

Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is one of the most common human genetic abnormalities, with a high prevalence in Sardinia, Italy. Evidence indicates that G6PD-deficient patients are protected against vascular disease. Little is known about the relationship between G6PD deficiency and diabetes mellitus. The purpose of this study was to compare G6PD deficiency prevalence in Sardinian diabetic men with severe retinal vascular complications and in age-matched non-diabetic controls and ascertain whether G6PD deficiency may offer protection against this vascular disorder. Erythrocyte G6PD activity was determined using a quantitative assay in 390 diabetic men with proliferative diabetic retinopathy (PDR) and 390 male non-diabetic controls, both aged ≥50 years. Conditional logistic regression models were used to investigate the association between G6PD deficiency and diabetes with severe retinal complications. G6PD deficiency was found in 21 (5.4 %) diabetic patients and 33 (8.5 %) controls (P=0.09). In a univariate conditional logistic regression model, G6PD deficiency showed a trend for protection against diabetes with PDR, but the odds ratio (OR) fell short of statistical significance (OR=0.6, 95% confidence interval=0.35-1.08, P=0.09). In multivariate conditional logistic regression models, including as covariates G6PD deficiency, plasma glucose, and systemic hypertension or systolic or diastolic blood pressure, G6PD deficiency showed no statistically significant protection against diabetes with PDR. The prevalence of G6PD deficiency in diabetic men with PDR was lower than in age-matched non-diabetic controls. G6PD deficiency showed a trend for protection against diabetes with PDR, but results were not statistically significant.

Aldehyde dehydrogenase 2 (ALDH2) detoxifies aldehyde produced during ethanol metabolism and oxidative stress. A genetic defect in this enzyme is common in East Asians and determines alcohol consumption behaviors. We investigated the impact of genetically determined ALDH2 activity on diabetic microvascular and macrovascular complications in relation to drinking habits in Japanese patients with type 2 diabetes mellitus. An ALDH2 single-nucleotide polymorphism (rs671) was genotyped in 4,400 patients. Additionally, the relationship of clinical characteristics with ALDH2 activity (ALDH2 *1/*1 active enzyme activity vs. *1/*2 or *2/*2 inactive enzyme activity) and drinking habits (lifetime abstainers vs. former or current drinkers) was investigated cross-sectionally (n = 691 in *1/*1 abstainers, n = 1,315 in abstainers with *2, n = 1,711 in *1/*1 drinkers, n = 683 in drinkers with *2). The multiple logistic regression analysis for diabetic complications was adjusted for age, sex, current smoking habits, leisure-time physical activity, depressive symptoms, diabetes duration, body mass index, hemoglobin A1c, insulin use, high-density lipoprotein cholesterol, systolic blood pressure and renin-angiotensin system inhibitors use. Albuminuria prevalence was significantly lower in the drinkers with *2 than that of other groups (odds ratio [95% confidence interval (CI)]: *1/*1 abstainers as the referent, 0.94 [0.76–1.16] in abstainers with *2, 1.00 [0.80–1.26] in *1/*1 drinkers, 0.71 [0.54–0.93] in drinkers with *2). Retinal photocoagulation prevalence was also lower in drinkers with ALDH2 *2 than that of other groups. In contrast, myocardial infarction was significantly increased in ALDH2 *2 carriers compared with that in ALDH2 *1/*1 abstainers (odds ratio [95% CI]: *1/*1 abstainers as the referent, 2.63 [1.28–6.13] in abstainers with *2, 1.89 [0.89–4.51] in *1/*1 drinkers, 2.35 [1.06–5.79] in drinkers with *2).

The Japan Diabetes Society (JDS) has recommended target levels of glycemic control based on guidelines for the management of diabetes mellitus (DM). The Japan Society of Ningen Dock created a database of subjects receiving annual health examinations nationwide. Using this database, we evaluated the efficacy of current treatment for patients with DM based on the JDS recommendations. This multicenter, retrospective study was conducted using data obtained from 21 institutions across Japan. In order to assess the level of glycemic control in the Japanese population, we analyzed previously obtained measurements of HbA1c in 7,180 patients 20 to 79 years of age (mean age: 57.9 ± 8.7 years, 6,007 men and 1,173 women) taking DM medications. According to the JDS guidelines, 44.7% of the patients fell into the good glycemic control group, with an HbA1c level of <7.0% while 22.4% were classified into the poor glycemic control group, with an HbA1c level of ≥ 8.0%. The control of other arteriosclerosis risk factors deteriorated as the glycemic control deteriorated. Lifestyle factors were strongly found to be associated with glycemic control in the patients receiving DM treatment. Aggressive lifestyle modification is needed to improve glycemic control in patients with DM.

The objective of this analysis is to project the long-term impacts on life expectancy and occurrence over 5, 10, and 40 years of microvascular and macrovascular complications of diabetes when using different haemoglobin A1c (HbA1c) thresholds for intensifying treatment of type 2 diabetes. A flexible, discrete-event simulation model has been developed to evaluate alternative treatment strategies based on the United Kingdom Prospective Diabetes Study Outcomes Model. In the present analysis, the model is used to investigate the impact of alternative HbA1c thresholds for treatment intensification ranging from 7.0 to 9.0%. For each intensification strategy, the model is run using 80 simulated patients for each of 1224 patient profiles from the Real-Life Effectiveness and Care Patterns of Diabetes Management study (for a total of 97,920 simulated patients) to project the number of patients who will experience diabetes-related complications over time. The use of lower HbA1c thresholds for intensifying treatment is associated with improved long-term outcomes. When the HbA1c threshold for intensifying therapy from oral treatment to basal insulin (T1) is 7.0% and the threshold for intensifying basal insulin to multiple-dose insulin (T2) is 7.0%, simulated patients spend 54% of their time with HbA1c >7.0%, but 95% of their time with HbA1c >7.0% if T1 and T2 are set to 9.0%. More aggressive or proactive treatment postures are projected to reduce clinical events, including diabetes-related deaths and diabetes-related complications, particularly myocardial infarctions (MIs). When T1 and T2 are set to 7.0%, there are 592 fewer diabetes-related deaths in the first 5 years of the simulation and 3740 fewer deaths over 40 years compared with the results when T1 and T2 are set to 9.0%. These decreases in deaths were also associated with a 0.35 year gain in projected life expectancy. Compared with an aggressive strategy with both T1 and T2 being 7%, 644 more patients are projected to

We have recently reported that the attitude of patients toward risk could be a factor in the progression of diabetic complications. In general, risk preference is closely related to socioeconomic status (SES), which includes factors such as age, sex, income, and educational attainment. We aimed to determine the effect of SES and behavioral propensity on the progress of diabetic complications in patients with type 2 diabetes mellitus (T2DM). We conducted a survey of 238 patients with difficult-to-control T2DM treated at a hospital in Japan using a modified behavioral economics questionnaire that included questions related to SES. The patients had been referred by general practitioners or other departments in the hospital because of poor metabolic control or unstable complications. Educational attainment was significantly associated with progression of retinopathy in patients <65 years of age. Educational attainment of a high school diploma (12 years of education) or lower was a significant risk factor, but there were no differences among levels of attainment beyond high school (13-16 years or more of education). Behavioral propensities were also weakly associated with complications, but not as much as educational attainment. Personal income level and economic status did not show an association with the retinopathy levels. Lower educational attainment is a strong risk factor for diabetic retinopathy, and it is independent of the economic status. The result suggests that cognitive function may play an important role in the progression of diabetic retinopathy in patients with T2DM.

Endoscopic third ventriculostomy (ETV) has become the procedure of choice for the treatment of obstructive hydrocephalus in children and adults. Endocrinological complications of ETV in children are rare. Diabetes insipidus (DI) is the most common and accounts for only 0.5% of complications from ETV. The majority of documented cases are transient. To date, there are no documented cases of multiple pituitary hormone deficiencies. We present here a 6-year-old girl with growth hormone deficiency and permanent DI which developed as a complication of ETV. This patient is unique in both demonstrating multiple pituitary hormone deficiencies and the classical triphasic response of DI after ETV. We postulate that these complications were caused by compression of the pituitary stalk and hypothalamic injury during the procedure. We compare our case presentation to experimental studies conducted in rats.

Intensive treatment (INT) of type 1 diabetes reduces the incidence of cardiovascular disease (CVD) events compared with conventional treatment (CONV), but it also results in more weight gain. Our objective was to examine whether excessive weight gain from INT of type 1 diabetes is independently associated with subsequent CVD events. Quartiles (Q) of weight gain in 1,213 participants aged 18 years and older at enrollment in the Diabetes Control and Complications Trial (DCCT) were determined within randomized treatment groups (INT vs. CONV) using change in BMI from baseline to the closeout DCCT visits. Effects of this weight gain on CVD risk factors and outcomes during an additional 20 years of observational follow-up were then determined. The Q4 INT group experienced greater proportional weight gain (median change in BMI, 6.08 kg/m 2 ), increases in CVD risk factors, and need for medications for hypertension and lipids compared with the Q1-3 INT and comparable CONV groups. Over a mean of 26 years of follow-up, the numbers of major and total CVD events were not statistically different in Q4 compared with Q1-3 of either the INT or CONV group. By year 14, however, the incident CVD event curve became significantly higher in the Q4 INT group than in the Q1-3 INT groups ( P = 0.024) and was similar to that for the CONV group. For the first 13 years after DCCT, INT for type 1 diabetes reduced macrovascular events compared with CONV, even when excessive weight gain occurred. After this, total CVD events significantly increased in the Q4 INT group, becoming equivalent to those in the CONV group. Longer follow-up is needed to determine whether this trend continues and results in more major CVD events. © 2017 by the American Diabetes Association.

We present a post hoc analysis of 17,530 questionnaires collected as part of the 2012 screening for neuropathy using Norfolk Quality of Life tool in patients with diabetes in Romania, to assess the impact on foot complications of time between the onset of symptoms of diabetes/its complications and the physician visit. Odds ratios (ORs) for self-reporting neuropathy increased from 1.16 (95% CI: 1.07–1.25) in those who sought medical care in 1–6 months from symptoms of diabetes/its complications onset to 2.27 in those who sought medical care >2 years after symptoms onset. The ORs for having a history of foot ulcers were 1.43 (95% CI: 1.26–1.63) in those who sought medical care in 1–6 months and increased to 3.08 (95% CI: 2.59–3.66) in those who sought medical care after >2 years from symptoms of diabetes/its complications onset. The highest ORs for a history of gangrene (2.49 [95% CI: 1.90–3.26]) and amputations (2.18 [95% CI: 1.60–2.97]) were observed in those who sought medical care after >2 years following symptoms onset. In conclusion, we showed that waiting for >1 month after symptoms onset dramatically increases the risk of diabetic foot complications. These results show the need for accessible educational programs on diabetes and its chronic complications and the need to avoid delays in reporting. PMID:28018920

To study the time and cost involved in the care of newly registered outpatients with Type 2 diabetes mellitus (DM), compared with patients with hypertension and/or hyperlipidaemia (HTL). A total of 313 patients with DM and 58 patients with HTL without diabetes were registered on their first visits to 11 diabetes clinics across Japan. The time and cost involved in their care was recorded over the following 5 months. In the first 3 months, there was an extensive time commitment to both groups. The time spent by physicians was 1.5 times longer for DM than for HTL. The total care time spent by all the care providers for DM was twice that for HTL. The cost of DM care was twice that for HTL, with the cost of medicines excluded. However, half of the cost for DM was for laboratory tests. When these were excluded, and the remaining cost divided by the time spent, the amount for DM was half of that for HTL. Over the 5 months, mean glycated haemoglobin (HbA(1c)) in DM patients improved from 8.0% to 6.5%, and 72% of DM patients achieved the glycaemic target of HbA(1c) < or = 6.5%. DM care in a diabetes clinic requires a great deal more time and resources than HTL to achieve the best outcome. An educational system for self care, presently lacking in the primary care setting in Japan, would improve glycaemic control for DM patients in the community.

Aflibercept is the most recently approved vascular endothelial growth factor (anti-VEGF) inhibitor for the management of diabetic macular edema and diabetic retinopathy. The purpose of this article is to review the efficacy and safety of aflibercept in the management of diabetic eye complications and to describe its place in therapy. Anti-VEGF agents have been noted in clinical trials to be superior to laser photocoagulation, the standard therapy ( P < .0001, P ≤ .0085, respectively). Aflibercept has been comparatively studied with other anti-VEGF agents, namely, bevacizumab and ranibizumab, and noted to be equally efficacious and safe in patients with mild visual acuity loss ( P > .50). However, in the treatment of patients with diabetic macular edema having moderate to severe visual acuity loss, aflibercept outperformed the other 2 anti-VEGF agents (aflibercept vs bevacizumab, P < .001; aflibercept vs ranibizumab, P = .003). However, additional studies are needed to fully appreciate the long-term safety and efficacy of aflibercept and the anti-VEGF therapy class.

The effects of intensive glucose control on cardiovascular events in patients with long-standing type 2 diabetes mellitus remain uncertain. We randomly assigned 1791 military veterans (mean age, 60.4 years) who had a suboptimal response to therapy for type 2 diabetes to receive either intensive or standard glucose control. Other cardiovascular risk factors were treated uniformly. The mean number of years since the diagnosis of diabetes was 11.5, and 40% of the patients had already had a cardiovascular event. The goal in the intensive-therapy group was an absolute reduction of 1.5 percentage points in the glycated hemoglobin level, as compared with the standard-therapy group. The primary outcome was the time from randomization to the first occurrence of a major cardiovascular event, a composite of myocardial infarction, stroke, death from cardiovascular causes, congestive heart failure, surgery for vascular disease, inoperable coronary disease, and amputation for ischemic gangrene. The median follow-up was 5.6 years. Median glycated hemoglobin levels were 8.4% in the standard-therapy group and 6.9% in the intensive-therapy group. The primary outcome occurred in 264 patients in the standard-therapy group and 235 patients in the intensive-therapy group (hazard ratio in the intensive-therapy group, 0.88; 95% confidence interval [CI], 0.74 to 1.05; P=0.14). There was no significant difference between the two groups in any component of the primary outcome or in the rate of death from any cause (hazard ratio, 1.07; 95% CI, 0.81 to 1.42; P=0.62). No differences between the two groups were observed for microvascular complications. The rates of adverse events, predominantly hypoglycemia, were 17.6% in the standard-therapy group and 24.1% in the intensive-therapy group. Intensive glucose control in patients with poorly controlled type 2 diabetes had no significant effect on the rates of major cardiovascular events, death, or microvascular complications with the exception of

Background To estimate the incidence of complications, life expectancy and diabetes related mortality in the Mexican diabetic population over the next two decades using data from a nation-wide, population based survey and the United Kingdom Prospective Diabetes Study (UKPDS) outcome model Methods The cohort included all patients with type 2 diabetes evaluated during the National Health and Nutrition Survey (ENSANut) 2006. ENSANut is a probabilistic multistage stratified survey whose aim was to measure the prevalence of chronic diseases. A total of 47,152 households were visited. Results are shown stratified by gender, time since diagnosis (> or ≤ to 10 years) and age at the time of diagnosis (> or ≤ 40 years). Results The prevalence of diabetes in our cohort was 14.4%. The predicted 20 year-incidence for chronic complications per 1000 individuals are: ischemic heart disease 112, myocardial infarction 260, heart failure 113, stroke 101, and amputation 62. Furthermore, 539 per 1000 patients will have a diabetes-related premature death. The average life expectancy for the diabetic population is 10.9 years (95%CI 10.7-11.2); this decreases to 8.3 years after adjusting for quality of life (CI95% 8.1-8.5). Male sex and cases diagnosed after age 40 have the highest risk for developing at least one major complication during the next 20 years. Conclusions Based on the current clinical profile of Mexican patients with diabetes, the burden of disease related complications will be tremendous over the next two decades. PMID:21214916

This case-control study investigated the associations of a history of hypertension, hypercholesterolemia, and diabetes mellitus with the risk of Parkinson's disease (PD) in Japan. Included were 249 cases within 6 years of onset of PD. Controls were 368 inpatients and outpatients without a neurodegenerative disease. Data on the vascular risk factors and confounders were obtained from a self-administered questionnaire. The vascular risk factors were defined based on drug treatment. Adjustment was made for sex, age, region of residence, pack-years of smoking, years of education, leisure-time exercise, body mass index, dietary intake of energy, cholesterol, vitamin E, alcohol, and coffee and the dietary glycemic index. The proportions of hypertension, hypercholesterolemia, and diabetes mellitus prior to the onset of PD were 23.7%, 9.6%, and 4.0%, respectively, in cases. Hypertension, hypercholesterolemia, and diabetes mellitus were significantly associated with a decreased risk of PD: the adjusted ORs were 0.43 (95% CI: 0.29-0.64), 0.58 (95% CI: 0.33-0.97), and 0.38 (95% CI: 0.17-0.79), respectively. No significant differences were observed in the association of vascular risk factors with the risk of PD between men and women. We found evidence of significant inverse associations of hypertension, hypercholesterolemia, and diabetes mellitus with the risk of PD in Japan. Further well-designed investigations of the association of vascular risk factors with the risk of PD are needed, particularly large-scale prospective studies in Asia. Copyright 2010 Elsevier B.V.

Reduced physical activity and high calories up-take along with carbohydrates based diet are considered to be a leading cause of diabetes mellitus rise in western countries. Together with rise in DM morbidity, increase of complicated diabetes is also observed. Pancreas transplantation occurred to be a milestone in diabetic patient management. Guine pig pancreatic islets isolation performed for the first time by Moskalewski in 1965 and updates of his method have given an opportunity to introduce allogenic isolated islets transplantation to clinical usage. For the first time in Poland clinical allotransplantation of isolated pancreatic islets took place in Department of General Surgery and Transplantology of Medical University of Warsaw in 12's June 2008. Unfortunately, unsatisfying results of islet transplantation, specially short period of insulin independence after successful transplantation related with multifactor islet function lost, reduce clinical indications. In this publication we have analyzed known and potential factors of islet lost and we have tried to find way to prevent them, with a long period insulin-independence after transplantation as a main goal.

Highlights: {yields} Telmisartan, an angiotensin receptor blocker, acts as a partial PPAR{gamma} agonist. {yields} The protective effects of telmisartan against diabetic vascular injury were associated with attenuation of vascular NF{kappa}B activation and TNF {alpha}. {yields} PPAR{gamma} activity of telmisartan was involved in the normalization of vascular PPAR{gamma} downregulation in diabetic mice. {yields} We provided the first evidence indicating that PPAR{gamma} activity of telmisartan contributed to the protective effects of telmisartan against diabetic vascular complication. -- Abstract: Experimental and clinical data support the notion that peroxisome proliferator-activated receptor {gamma} (PPAR{gamma}) activation is associated with anti-atherosclerosis as well as anti-diabetic effect. Telmisartan,more » an angiotensin receptor blocker (ARB), acts as a partial PPAR{gamma} agonist. We hypothesized that telmisartan protects against diabetic vascular complications, through PPAR{gamma} activation. We compared the effects of telmisartan, telmisartan combined with GW9662 (a PPAR{gamma} antagonist), and losartan with no PPAR{gamma} activity on vascular injury in obese type 2 diabetic db/db mice. Compared to losartan, telmisartan significantly ameliorated vascular endothelial dysfunction, downregulation of phospho-eNOS, and coronary arterial remodeling in db/db mice. More vascular protective effects of telmisartan than losartan were associated with greater anti-inflammatory effects of telmisartan, as shown by attenuation of vascular nuclear factor kappa B (NF{kappa}B) activation and tumor necrosis factor {alpha}. Coadministration of GW9662 with telmisartan abolished the above mentioned greater protective effects of telmisartan against vascular injury than losartan in db/db mice. Thus, PPAR{gamma} activity appears to be involved in the vascular protective effects of telmisartan in db/db mice. Moreover, telmisartan, but not losartan, prevented the downregulation

Traditionally, basal rate profiles in continuous subcutaneous insulin infusion therapy are individually adapted to cover expected insulin requirements. However, whether this approach is indeed superior to a more constant BR profile has not been assessed so far. This study analysed the associations between variability of BR profiles and acute and chronic complications in adult type 1 diabetes mellitus. BR profiles of 3118 female and 2427 male patients from the "Diabetes-Patienten-Verlaufsdokumentation" registry from Germany and Austria were analysed. Acute and chronic complications were recorded 6 months prior and after the most recently documented basal rate. The "variability index" was calculated as variation of basal rate intervals in percent and describes the excursions of the basal rate intervals from the median basal rate. The variability Index correlated positively with severe hypoglycemia (r = .06; p<0.001), hypoglycemic coma (r = .05; p = 0.002), and microalbuminuria (r = 0.05; p = 0.006). In addition, a higher variability index was associated with higher frequency of diabetic ketoacidosis (r = .04; p = 0.029) in male adult patients. Logistic regression analysis adjusted for age, gender, duration of disease and total basal insulin confirmed significant correlations of the variability index with severe hypoglycemia (β = 0.013; p<0.001) and diabetic ketoacidosis (β = 0.012; p = 0.017). Basal rate profiles with higher variability are associated with an increased frequency of acute complications in adults with type 1 diabetes.

Epidemiological evidence of type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease in Japan.

PubMed

Saito, Isao

2012-01-01

Although epidemiological studies in the US and Europe have confirmed that type 2 diabetes mellitus (DM) is associated with an increased risk of cardiovascular disease (CVD) events, evidence is limited in Japan. Earlier studies in Japan showed that hypertension has a major effect on atherosclerosis in relatively lean subjects, with type 2 DM contributing more to CVD events, because of a decline in blood pressure levels in both sexes and an increase in body mass index in men. Recent cohort studies in Japan using baseline assessments carried out during the 1990s have confirmed that type 2 DM is associated with an increased risk of coronary heart disease (CHD) and all types of stroke, except hemorrhagic stroke. In addition, the metabolic syndrome, a constellation of metabolic risk factors, was shown to predict CVD events in Japanese people, independent of the presence or absence of obesity. The strong association of type 2 DM with CHD (hazard ratio: 1.5-4) and ischemic stroke (hazard ratio: 2-4) events was confirmed in Japanese adults. Individuals with impaired glucose tolerance or impaired fasting glucose were also shown to have an increased risk of a CHD event, but not a stroke.

This investigation was made with reference to the changes of serum angiotensin converting enzyme (SACE) activity in type 2 diabetes and its vascular complications. SACE activity was studied in 127 type 2 diabetic patients and 90 healthy persons by using a spectrophotometric assay. The results showed SACE activity was obviously higher in diabetic patients (459.51 +/- 175.85 U) than in healthy persons (321.14 +/- 121.27 U); SACE activity was significantly higher in type 2 diabetic patients with diabetic nephropathy (548.27 +/- 166.60 U) than in patients without diabetic nephropathy (383.2 +/- 139.00 U), but there was no difference between patients with microalbuminuria and macroalbuminuria; no statistical difference was detected in SACE activity between diabetic patients with diabetic retinopathy (465.64 +/- 178.93 U) and without retinopathy (449.07 +/- 170.04 U); SACE activity was not associated with the course of diabetes, blood pressure, blood lipid and blood glucose. These data suggest that raised SACE activity might only play a role in the initiation of type 2 diabetes and diabetic nephropathy, but not relate to the progress of diabetic nephropathy, the onset of diabetic retinopathy and hypertension.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disorder of the liver. The relationship between NAFLD and type 2 diabetes remains largely unknown. The aim of the present study was to determine the incidence of complications arising from the interaction between NAFLD and type 2 diabetes. A total of 212 individuals with type 2 diabetes were included in the study. The presence of NAFLD was determined in individuals using abdominal ultrasonography for the diagnosis of fatty liver disease. Patients were divided into three groups based on the duration of diabetes and NAFLD diagnosis. Type 2 diabetes patients were placed in group A; patients with type 2 diabetes longer than NAFLD were placed in group B; and patients with NAFLD longer than type 2 diabetes were placed in group C. All individuals had undergone electrocardiogram, blood pressure measurements, and thorough medical history and physical examinations (Doppler ultrasound, electrophysiology, fundoscopy, cardiac computed tomography). Laboratory measurements included fasting blood glucose, glycated hemoglobin, oral glucose tolerance test, liver and renal function, lipid profile, and urinary albumin excretion. Compared with groups A and B, the patients of group C showed a higher prevalence of significant coronary artery disease and hypertension (P < 0.05). Compared with groups A and B, the patients of group C showed a lower prevalence of diabetic retinopathy and diabetic peripheral neuropathy (P < 0.05). There was no significant difference in the prevalence of diabetic nephropathy among the three groups (P > 0.05). NAFLD combined with type 2 diabetes is associated with the presence of significant coronary artery disease and hypertension. © 2016 The Authors.

Genome-wide association studies have resulted in the identification of the FTO gene as an important genetic determinant of diabetes mellitus. The aim of this study was to confirm the role of this gene in the development of DM in the Czech-Slavonic population and to analyse whether this gene is associated with common DM complications. Two groups of patients (814 with T1DM and 848 with T2DM) and a group of healthy controls (2339 individuals) - both of Czech origin - were genotyped for the FTO rs17817449 SNP. ANOVA and logistic regression were used for the statistical evaluations. The frequency of the GG genotype was significantly higher in T2DM (25.4% vs. 16.7%, P<0.0005) but not in T1DM patients (19.3% vs. 16.7%, P=0.20) than in controls. The increased risk of development of diabetic nephropathy was observed both for T1DM patients (GG vs. TT homozygotes, P<0.01) and T2DM patients (G carriers vs. TT homozygotes, P<0.05). FTO genotype predicted the development of diabetic neuropathy (GG vs. TT comparison; P<0.01) in the T2DM patients only. No association between FTO genotype and development of retinopathy was detected. All presented values are after adjustment for age, sex, BMI and duration of diabetes. We confirm the association between the FTO rs17817449 SNP and susceptibility to T2DM in the Czech-Slavonic population. The same variant is associated with a spectrum of chronic complications in both types of diabetes. Copyright © 2017 Elsevier B.V. All rights reserved.

HNF1A gene mutations are the most common cause of maturity-onset diabetes of the young (MODY) in the UK. Persons with HNF1A-MODY display sensitivity to sulphonylurea therapy; however, the long-term efficacy is not established. There is limited literature as to the prevalence of micro- and macrovascular complications in this unique cohort. The aim of this study was to determine the natural progression and clinical management of HNF1A-MODY diabetes in a dedicated MODY clinic. Sixty patients with HNF1A-MODY and a cohort of 60 BMI-, age-, ethnicity- and diabetes duration-matched patients with Type 1 diabetes mellitus participated in the study. All patients were phenotyped in detail. Clinical follow-up of the HNF1A-MODY cohort occurred on a bi-annual basis. Following a genetic diagnosis of MODY, the majority of the cohort treated with sulphonylurea therapy remained insulin independent at 84-month follow-up (80%). The HbA1c in the HNF1A-MODY group treated with sulphonylurea therapy alone improved significantly over the study period [from 49 (44-63) mmol/mol, 6.6 (6.2-7.9)% to 41 (31-50) mmol/mol, 5.9 (5-6.7)%; P = 0.003]. The rate of retinopathy was significantly lower than that noted in the Type 1 diabetes mellitus group (13.6 vs. 50%; P = 0.0001).There was also a lower rate of microalbuminuria and cardiovascular disease in the HNF1A-MODY group compared with the Type 1 diabetes mellitus group. This study demonstrates that the majority of patients with HNF1A-MODY can be maintained successfully on sulphonylurea therapy with good glycaemic control. We note a significantly lower rate of micro- and macrovascular complications than reported previously. The use of appropriate therapy at early stages of the disorder may decrease the incidence of complications. © 2015 Diabetes UK.

Information on the prevalence of gestational diabetes mellitus is scarce on national and international level. On July 1st, 2013, a general two-step screening was implemented in Germany harmonizing gestational diabetes diagnoses. We aim to provide prevalence estimates for gestational diabetes and pregnancy-related complications for the large region of North Rhine for the 12 months before and after introduction of the general screening. Routine care data covering all outpatient diagnoses of more than 150,000 pregnancies per 12-month period in women aged 15-55 years was used to determine cases of gestational diabetes. Gestational diabetes diagnosis and pregnancy-related complications were assessed according to the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Relative Risks for pregnancy-related complications were calculated in pregnancies with and without gestational diabetes. Before the screening, diagnosis of gestational diabetes was made in 6.02% of pregnancies and in 6.81% after this date (other types of diabetes mellitus: 1.67% and 1.76% respectively). The prevalence of GDM increased with age and was highest at age 36-40 years (8.45%). The relative increase in prevalence after introduction of the screening was highest in the age group≤25 years (24.9%). The frequency of pregnancy-related complications such as hypertension, pre-eclampsia, cesarean section was increased in pregnancies with gestational diabetes in comparison to those without independent of observation period. We found a high prevalence of gestational diabetes, which has relatively increased by 13.12% after the introduction of the general screening. Copyright © 2016 Elsevier Ireland Ltd.

The Aboriginal and Torres Strait Islander community has an increased risk of developing chronic illnesses including diabetes. Among people with diabetes, foot complications are common and make a significant contribution to the morbidity and mortality associated with this disease. The aim of this review was to systematically evaluate the literature comparing the rates of diabetes related foot complications in Aboriginal and Torres Strait Islander Australians to non-Indigenous Australians. MEDLINE, EMBASE, The Cochrane Library; PUBMED and CINAHL were searched from inception until August 2016. Inclusion criteria were: published cross-sectional or longitudinal studies reporting the prevalence of diabetes related foot complications in both a cohort of Aboriginal and Torres Strait Islander Australians and a cohort of one other Australian population of any age with diabetes. Risk of bias was assessed using the STROBE tool. Eleven studies including a total of 157,892 participants were included. Studies were set in Queensland, the Northern Territory and Western Australia, primarily in rural and remote areas. Aboriginal and Torres Strait Islander Australians experienced substantially more diabetes related foot complications with the mean age up to 14 years younger than non-Indigenous Australians. Aboriginality was associated with increased risk of peripheral neuropathy, foot ulceration and amputation. In several studies, Aboriginal and Torres Strait Islander Australians accounted for the vast majority of diabetes related foot complications (up to 91%) while comprising only a small proportion of the regional population. Reporting quality as assessed with the STROBE tool showed underreporting of: methods, sample description and potential sources of bias. There are no data available for some Australian states and for specific types of diabetes related foot complications. Aboriginal and Torres Strait Islander Australians have a 3-6 fold increased likelihood of experiencing a

More women are entering pregnancy with pre-existing diabetes. Disease severity, glycaemic control, and predictors of pregnancy complications may differ by race/ethnicity or educational attainment, leading to differences in adverse pregnancy outcomes. We used linked New York City hospital record and birth certificate data for 6291 singleton births among women with pre-existing diabetes between 1995 and 2003. We defined maternal race/ethnicity as non-Hispanic white, non-Hispanic black, Hispanic, South Asian, and East Asian, and education level as <12, 12, and >12 years. Our outcomes were pre-eclampsia, preterm birth (PTB) (<37 weeks gestation and categorised as spontaneous or medically indicated), as well as small-for-gestational age (SGA) and large-for-gestational age (LGA). Using multivariable binomial regression, we estimated the risk ratios for pre-eclampsia, SGA, and LGA. We used multivariable multinomial regression to estimate odds ratios (OR) for PTB. Compared with non-Hispanic white women with pre-existing diabetes, non-Hispanic black and Hispanic women with pre-existing diabetes had a 1.50-fold increased risk of pre-eclampsia compared with non-Hispanic whites with pre-existing diabetes, after full adjustment. Non-Hispanic black and Hispanic women with pre-existing diabetes had adjusted ORs of 1.72 [adj. 95% confidence interval (CI) 1.38, 2.15] and 1.65 [adj.95% CI 1.32, 2.05], respectively, for medically indicated PTB. South Asian women with pre-existing diabetes had the highest risk for having an SGA infant [adj. OR: 2.29; adj. 95% CI 1.73, 3.03]. East Asian ethnicity was not associated with these pregnancy complications. Non-Hispanic black, Hispanic, and South Asian women with pre-existing diabetes may benefit from targeted interventions to improve pregnancy outcomes. © 2013 The Authors.

Patients with type 2 diabetes (T2DM) demonstrate low dietary adherence and this is further aggravated with comorbid obesity. The aim of the present study was to assess diet quality in patients with T2DM and comorbid obesity compared to patients with T2DM alone and to examine the associations between comorbidities and diet quality. The sample consisted of 59 adult patients with diabesity (T2DM and comorbid obesity) and 94 patients with T2DM alone. All diabetes comorbidities and complications were recorded and diet quality was assessed with the Healthy Eating Index (HEI). Mean raw HEI of the diabese subjects was 81.9±7.1 and the diabetic subjects was 80.2±6.9. When HEI was adjusted to the sex, age and weight status, the diabese demonstrated a higher HEI. Among comorbidities, only renal disease decreased HEI. According to the principal component analysis of the total sample, adequate diet quality was explained by cardiovascular disease, cigarette smoking, alcohol consumption, peptic ulcer, sex, diabesity and diabetic foot syndrome. In the diabese, adequate HEI was explained by diabetic foot syndrome, smoking, drinking alcohol and having a family history of diabetes. Adult patients with T2DM demonstrate adequate diet quality. Different factors are associated with the adoption of a high quality diet between the diabese and the T2DM alone. Copyright © 2011 SEEN. Published by Elsevier Espana. All rights reserved.

The present study was planned to assess the possible protective effect of geraniol on cardiovascular complications in an animal model with diabetes. Diabetes was induced in rats by a single streptozotocin injection. In the treated group, geraniol (150mgkg -1 day -1 ) was administered orally starting from the 15th day after induction of diabetes, and ending after 7 weeks; diabetic control rats were given vehicle for the same period. At the end of the study, cardiac contractility was assessed by using a Millar microtip catheter in anesthetised rats, and cardiac conductivity determined by a surface ECG. Serum levels of glucose, cholesterol, triglyceride and adiponectin as well as urine 8-isoprostane were determined. In addition, cardiac superoxide dismutase (SOD) and catalase activity were measured. Geraniol administration significantly alleviated the attenuated cardiac systolic function associated with diabetes as indicated by inhibiting the decrease in the rate of rise (dP/dt max ) in ventricular pressure and the increase in systolic duration observed in diabetic rats. In addition, geraniol alleviated impaired diastolic function as shown by inhibiting the decrease in the rate of fall (dP/dt min ) in ventricular pressure and increased isovolumic relaxation constant (Tau) observed in diabetic rats. ECG recordings showed that geraniol prevented any increase in QTc and T-peak-T-end intervals, and markers of LV ischemia and arrhythmogenesis, seen in diabetic animals. Geraniol suppressed the exaggerated oxidative stress as evidenced by preventing the increase in 8-isoprotane. In diabetic heart tissue, geraniol prevented the inhibition in catalase activity but did not affect the heart SOD. Geraniol partially reduced hyperglycemia, prevented the hypercholesterolemia, but did not affect the serum level of adiponectin in diabetic animals. Results obtained in this study suggest that geraniol provides a potent protective effect against cardiac dysfunction induced by diabetes

Diabetes and its cardiovascular complications have been a major public health issue. These complications are mainly attributable to a severe imbalance between free radical and reactive oxygen species production and the antioxidant defense systems. Nuclear factor E2-related factor 2 (Nrf2) is a transcription factor that controls the basal and inducible expression of a battery of antioxidant enzyme genes and other cyto-protective phase II detoxifying enzymes. As a result, Nrf2 has gained great attention as a promising drug target for preventing diabetic cardiovascular complications. And while animal studies have shown that several Nrf2 activators manifest a potential to efficiently prevent the diabetic complications, their use in humans has not been approved due to the lack of substantial evidence regarding safety and efficacy of the Nrf2 activation. We provide here a brief review of a few clinically-used drugs that can up-regulate Nrf2 with the potential of extending their usage to diabetic patients for the prevention of cardiovascular complications and conclude with a closer inspection of dimethyl fumarate and its mimic members.

We aimed to investigate the association between serum 25-hydroxyvitamin D (25[OH]D) and microvascular complications in type 2 diabetes mellitus (T2DM) patients. It was hypothesized that lower 25(OH)D would be associated with increased microvascular complications in T2DM. A total of 257 T2DM patients (111 men, 146 women) who underwent diabetic microvascular complication (peripheral neuropathy, nephropathy, retinopathy) studies were recruited. Patients were categorized into 3 groups according to vitamin D status: vitamin D sufficient (n = 41, 25[OH]D ≥ 20 ng/mL), vitamin D insufficient (n = 132, 10 ≤ 25[OH]D < 20 ng/mL), and vitamin D deficient (n = 84, 25[OH]D < 10 ng/mL). In men, the prevalence of diabetic peripheral neuropathy (DPN) was significantly higher in patients with vitamin D deficiency than in those with insufficiency or sufficiency (38%, 11.7%, and 10%, respectively; P = .005). In addition, the prevalence of diabetic nephropathy (DN) was significantly higher in women with vitamin D deficiency than in the other 2 groups (40%, 20.6%, and 0%; P = .007). Compared with men in the vitamin D-sufficient group (reference), men in the vitamin D-deficient group had an increased risk of DPN after adjusting for confounding factors (odds ratio, 7.79; 95% confidence interval, 1.52-40.05). For women, when the vitamin D-sufficient group was used as a reference, those in the vitamin D-deficient group had an increased risk of DN after adjusting for confounding factors (odds ratio, 4.27; 95% confidence interval, 1.58-11.56). This present study found that a serum 25(OH)D level less than 10 ng/mL is independently associated with increased DPN in male patients and increased DN in female patients with T2DM.

As the associations between actinic keratosis (AK) and diabetes complications in patients with diabetes mellitus (DM) have never been investigated, this study aimed to evaluate any such associations in patients with DM. This retrospective cohort study analyzed clinical data for DM patients aged>40 years who had undergone the health examination recommended by the South Korea National Health Insurance Program between 2009 and 2012 (n=2,056,580). All of these patients were classified according to the presence of diabetic retinopathy (DR), end-stage renal disease (ESRD) and history of DVD; myocardial infarction, stroke, transient ischaemic attacks. Newly diagnosed AK was identified using claims data from baseline to the date of diagnosis or 31 December 2015, whichever came first. Of the 2,056,580 patients with DM, 6404 (0.31%) developed AK. Those patients in the DR, ESRD and CVD groups were more likely to be diagnosed with AK (P<0.001, by log-rank test). After adjusting for age and gender, the risks for AK were significantly higher in the DR, ESRD and CVD groups: HR (95% CI): 1.29 (1.21-1.39), HR: 4.24 (3.28-5.47) and HR: 1.22 (1.13-1.31), respectively. This study has revealed that the incidence of AK is higher in diabetes patients with ocular, renal and cardiovascular complications. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Background Health of migrants is a major public health challenge faced by governments and policy makers. Asian Indians are among the fastest growing migration groups across Asia and the world, but the impact of migration and acculturation on diabetes and diabetes-related eye complications among Indians living in urban Asia remains unclear. Methodologies/Principal Findings We evaluated the influence of migration and acculturation (i.e., migration status and length of residence) on the prevalence of type-2 diabetes mellitus (T2DM) and diabetes-related eye complications (diabetic retinopathy (DR) and cataract), among first-generation (defined as participant born in India with both parents born in India, n = 781) and second-generation (participants born in Singapore with both parents born in India, n = 1,112) Indian immigrants from a population-based study of Adult Indians in Singapore. Diabetes was defined as HbA1c≥6.5%, use of diabetic medication or a physician diagnosis of diabetes. Retinal and lens photographs were graded for the presence of DR and cataract. Compared to first generation immigrants, second generation immigrants had a higher age- and gender-standardized prevalence of T2DM (34.4% versus 29.0%, p<0.001), and, in those with T2DM, higher age- and gender-standardized prevalence of DR (31.7% versus 24.8%, p<0.001), nuclear cataract (13.6% versus 11.6%, p<0.001), and posterior sub-capsular cataract (6.4% versus 4.6%, p<0.001). Among first generation migrants, longer length of residence was associated with significantly younger age of diagnosis of diabetes and greater likelihood of having T2DM and diabetes-related eye complications. Conclusion Second generation immigrant Indians and longer length of residence are associated with higher prevalence of diabetes and diabetes-related complications (i.e., DR and cataract) among migrant Indians living in Singapore. These data highlight potential worldwide impacts of migration patterns on the risk and

Work-related factors associated with self-care and psychological health among people with type 2 diabetes in Japan.

This study on individuals with type 2 diabetes living in Japan aimed to examine work-related factors that influence self-care and psychological health among people. A cross-sectional survey was conducted among 121 working adults with type 2 diabetes. A self-report questionnaire assessed demographics, work characteristics, self-disclosure of diabetes, support in the workplace, work-related difficulties due to diabetes, and workplace conformity. Dietary self-care, exercise, depression, and emotional distress were also evaluated. The results indicated statistically significant influence of working night shifts, self-disclosure of diabetes, and workplace conformity on dietary self-care. Work-related difficulties due to diabetes had negative effects on depression and emotional distress, and job control and support in the workplace were found to be correlated with emotional distress. These findings suggest that work-related factors have an impact on some forms of self-care activities and psychological health and that it is important to increase understanding of these issues and provide appropriate support for workers through education and counseling and adjustments in the workplace. © 2012 Wiley Publishing Asia Pty Ltd.

Epidemiology, management, complications and costs associated with type 2 diabetes in Brazil: a comprehensive literature review

PubMed Central

2013-01-01

Background With an estimated 74% of all deaths attributable to non-communicable diseases (NCDs) in 2010, NCDs have become a major health priority in Brazil. The objective of the study was to conduct a comprehensive literature review on diabetes in Brazil; specifically: the epidemiology of type 2 diabetes, the availability of national and regional sources of data (particularly in terms of direct and indirect costs) and health policies for the management of diabetes and its complications. Methods A literature search was conducted using PubMed to identify articles containing information on diabetes in Brazil. Official documents from the Brazilian government and the World Health Organization, as well as other grey literature and official government websites were also reviewed. Results From 2006 to 2010, an approximate 20% increase in the prevalence of self-reported diabetes was observed. In 2010, it was estimated that 6.3% of Brazilians aged 18 years or over had diabetes. Diabetes was estimated to be responsible for 278,778 years of potential life lost for every 100,000 people. In 2013, it is estimated that about 7% of patients with diabetes has had one or more of the following complications: diabetic foot ulcers, amputation, kidney disease, and fundus changes. The estimated annual direct cost of diabetes was USD $3.952 billion in 2000; the estimated annual indirect cost was USD $18.6 billion. The two main sources of data on diabetes are the information systems of the Ministry of Health and surveys. In the last few years, the Brazilian Ministry of Health has invested considerably in improving surveillance systems for NCDs as well as implementing specific programmes to improve diagnosis and access to treatment. Conclusions Brazil has the capacity to address and respond to NCDs due to the leadership of the Ministry of Health in NCD prevention activities, including an integrated programme currently in place for diabetes. Strengthening the surveillance of NCDs is a

Sick individuals and children are exempted from fasting Ramadan. Fasting by type 1 diabetes patients might predispose to acute complications. There are no guidelines on fasting safety or its impact on diabetes control in children and adolescents. We aim to assess patients' attitude towards fasting, frequency of complications and impact on glycemic control in children with type 1 diabetes. 65 children with type 1 diabetes were enrolled. The study involved 2 hospital visits. Questionnaires were filled in each visit and HbA1c was recorded. Log books indicating symptomatic hypoglycemia and hyperglycemia leading to breaking fast were obtained. Majority of subjects were willing to fast and 75% were encouraged by parents to do. 57% and 26% fasted more than half and all through the month respectively. 52% had, at least, one episode of hypoglycemia and 29% had hyperglycemia with one episode of ketoacidosis. All patients broke fast in response to symptomatic hypoglycemia/hyperglycemia. There was no significant difference between the frequency of complications in the pump or the Multiple Daily Injection (MDI) groups. Mean HbA1c increased from 70mmol/mol to 73mmol/mol. The difference was not statistically significant. Children and adolescents with type 1 diabetes are keen to fast Ramadan and they are able to fast a significant number of days. Hypoglycemia and hyperglycemia are not uncommon with no difference between Pump or in MDI users. Breaking fast on occurrence of complications makes fasting safe. Glycemic control might deteriorate during the month and the following Eid. Copyright © 2017 Elsevier B.V. All rights reserved.

To investigate whether obesity, hypertension, and diabetes mellitus (DM) would increase post-nephrectomy complication rates using standardized classification method. We retrospectively included 843 patients from March 2006 to November 2012, of whom 613 underwent radical nephrectomy (RN) and 229 had partial nephrectomy (PN). Modified Clavien classification system was applied to quantify complication severity of nephrectomy. Fisher's exact or chi-square test was used to assess the relationship between complication rates and obesity, hypertension, as well as DM. The prevalence of obesity, hypertension, and DM was 11.51%, 30.84%, 8.78%, respectively. The overall complication rate was 19.31%, 30.04%, 35.71% and 36.36% for laparoscopic radical nephrectomy (LRN), open-RN, LPN and open-PN respectively. An increasing trend of low grade complication rate as BMI increased was observed in LRN (P=.027) and open-RN (P<.001). Obese patients had greater chance to have low grade complications in LRN (OR=4.471; 95% CI: 1.290-17.422; P=0.031) and open-RN (OR=2.448; 95% CI: 1.703-3.518; P<.001). Patients with hypertension were more likely to have low grade complications, especially grade ii complications in open-RN (OR=1.526; 95% CI: 1.055-2.206; P=.026) and open PN (OR=2.032; 95% CI: 1.199-3.443; P=.009). DM was also associated with higher grade i complication rate in open-RN (OR=2.490; 95% CI: 331-4.657; P=.016) and open-PN (OR=4.425; 95% CI: 1.815-10.791; P=.013). High grade complication rates were similar in comparison. Obesity, hypertension, and DM were closely associated with increased post-nephrectomy complication rates, mainly low grade complications.

The Big Entity of New RNA World: Long Non-Coding RNAs in Microvascular Complications of Diabetes.

PubMed

Raut, Satish K; Khullar, Madhu

2018-01-01

A major part of the genome is known to be transcribed into non-protein coding RNAs (ncRNAs), such as microRNA and long non-coding RNA (lncRNA). The importance of ncRNAs is being increasingly recognized in physiological and pathological processes. lncRNAs are a novel class of ncRNAs that do not code for proteins and are important regulators of gene expression. In the past, these molecules were thought to be transcriptional "noise" with low levels of evolutionary conservation. However, recent studies provide strong evidence indicating that lncRNAs are (i) regulated during various cellular processes, (ii) exhibit cell type-specific expression, (iii) localize to specific organelles, and (iv) associated with human diseases. Emerging evidence indicates an aberrant expression of lncRNAs in diabetes and diabetes-related microvascular complications. In the present review, we discuss the current state of knowledge of lncRNAs, their genesis from genome, and the mechanism of action of individual lncRNAs in the pathogenesis of microvascular complications of diabetes and therapeutic approaches.

[The Role of GRK2 and Its Potential as a New Therapeutic Target in Diabetic Vascular Complications].

PubMed

Taguchi, Kumiko

A decrease in nitric oxide (NO) production may induce pathological conditions associated with endothelial dysfunction and diabetes. Although a decrease in NO production caused by impaired Akt/endothelial nitric oxide synthesis (eNOS) signaling has been demonstrated at the aorta in the presence of diabetic vascular complications, little is known regarding the details of the mechanism. We identified G-protein-coupled receptor kinase 2 (GRK2) as a critical factor in diabetic endothelial dysfunction. GRK2 plays a role in many physiological functions including regulation of G-protein-coupled receptors (GPCRs). We found that the vasculature affected by type 2 diabetes expresses high levels of GRK2, which may induce endothelial dysfunction caused by impaired Akt/eNOS signaling. GRK2 activation also induces changes in the subcellular localization of GRK2 and β-arrestin 2, a downstream protein, from the cytosol to membrane. In mouse aorta GRK2 may be, on translocation, a key negative regulator and an important regulator of β-arrestin 2/Akt/eNOS signaling, which has been implicated in diabetic endothelial dysfunction. Furthermore, in the aortic membrane of type 2 diabetic model mice under insulin stimulation, the impaired Akt/eNOS signaling was improved by a selective GRK2 inhibitor. These results suggest that in diabetes the GRK2 inhibitor ameliorates vascular endothelial dysfunction via Akt/eNOS signaling by inhibiting GRK2 activity and enhancing β-arrestin 2 translocation to the membrane under GPCR or non-GPCR stimulation, thereby contributing to blood pressure- and blood glucose-lowering effects. We propose that the GRK2 inhibitor may be a promising therapeutic target for cardiovascular complications in type 2 diabetes.

Physicians have long recognized the association between diabetes mellitus and several pathologic conditions of the hand. The most commonly recognized maladies are limited joint mobility (LJM), Dupuytren's disease (DD), trigger finger (TF), and carpal tunnel syndrome (CTS). Incidence of these hand disorders has increased in the setting of diabetes. Collectively, these are described as diabetic hand syndrome. The aims were to find out the prevalence of hand disorders in diabetic patients, and to study the relation of these hand disorders with microvascular complications. This is an observational cross-sectional case-control study done over a period of 1 year Patients of type 2 DM, of age < 65 years, who visited Gandhi Memorial Hospital, Lucknow were enrolled and were described as cases. Age- and sex-matched nondiabetic individuals were taken in the control group. The data were analyzed using software SPSS. SPSS Inc. Released 2008. SPSS Statistics for Windows, Version 17.0. Chicago: SPSS Inc. Means and standard deviations were computed; the Student t-test and Chi-square (χ(2)) test were used as appropriate. A total of 400 subjects were studied, 200 each in the case and control groups. Of total 200 diabetic patients, 30% (60/200) patients had neuropathy, 37.5% (75/200) had nephropathy, and 44.5% (89/200) patients had retinopathy. In the study population, 67% patients were having one or more hand disorders, in which LJM was found in 40.5% (81/200) patients, DD was found in 19% (38/200) patients, TF in 16.5% (33/200), and CTS in 14% (28/200) patients. This study shows a high prevalence of hand disorders in diabetic patients and also correlates with the duration of type 2 DM, LJM being the most common hand disorder and more common in patients who have microvascular complications.

To test the hypothesis that non-invasive skin autofluorescence, a measure of advanced glycation end products, would provide a surrogate measure of long-term glycaemia and be associated with early markers of microvascular complications in adolescents with Type 1 diabetes. Forearm skin autofluorescence (arbitrary units) was measured in a cross-sectional study of 135 adolescents with Type 1 diabetes [mean ± sd age 15.6 ± 2.1 years, diabetes duration 8.7 ± 3.5 years, HbA 1c 72 ± 16 mmol/mol (8.7 ± 1.5%)]. Retinopathy, assessed using seven-field stereoscopic fundal photography, was defined as ≥1 microaneurysm or haemorrhage. Cardiac autonomic function was measured by standard deviation of consecutive RR intervals on a 10-min continuous electrocardiogram recording, as a measure of heart rate variability. Skin autofluorescence was significantly associated with age (R 2 = 0.15; P < 0.001). Age- and gender-adjusted skin autofluorescence was associated with concurrent HbA 1c (R 2 = 0.32; P < 0.001) and HbA 1c over the previous 2.5-10 years (R 2 = 0.34-0.43; P < 0.002). Age- and gender-adjusted mean skin autofluorescence was higher in adolescents with retinopathy vs those without retinopathy [mean 1.38 (95% CI 1.29, 1.48) vs 1.22 (95% CI 1.17, 1.26) arbitrary units; P = 0.002]. In multivariable analysis, retinopathy was significantly associated with skin autofluorescence, adjusted for duration (R 2 = 0.19; P = 0.03). Cardiac autonomic dysfunction was also independently associated with skin autofluorescence (R 2 = 0.11; P = 0.006). Higher skin autofluorescence is associated with retinopathy and cardiac autonomic dysfunction in adolescents with Type 1 diabetes. The relationship between skin autofluorescence and previous glycaemia may provide insight into metabolic memory. Longitudinal studies will determine the utility of skin autofluorescence as a non-invasive screening tool to predict future microvascular complications. © 2016 Diabetes UK.

To date no clinical trials have evaluated the role of dietary patterns on the incidence of microvascular diabetes complications. We hypothesized that a nutritional intervention based on the Mediterranean diet (MedDiet) would have greater protective effect on diabetic retinopathy and nephropathy than a low-fat control diet. This was a post hoc analysis of a cohort of patients with type 2 diabetes participating in the PREvención con DIeta MEDiterránea (PREDIMED) study, a multicenter randomized nutritional intervention trial conducted in a population at high cardiovascular risk. Individuals with type 2 diabetes who were free of microvascular complications at enrollment (n = 3,614, aged 55-80 years) were randomly assigned to one of three dietary interventions: MedDiet supplemented with extravirgin olive oil (MedDiet+EVOO), MedDiet supplemented with mixed nuts (MedDiet+Nuts), or a low-fat control diet. Two independent outcomes were considered: new onset of diabetic retinopathy and nephropathy. Hazard ratios (HRs) were calculated using multivariable-adjusted Cox regression. During a median follow-up of 6.0 years, we identified 74 new cases of retinopathy and 168 of nephropathy. Compared with the control diet, multivariable-adjusted HRs for diabetic retinopathy were 0.56 (95% CI 0.32-0.97) for the MedDiet+EVOO and 0.63 (0.35-1.11) for the MedDiet+Nuts. No between-group differences were found for nephropathy. When the yearly updated information on adherence to the MedDiet was considered, the HR for retinopathy in the highest versus the lowest quintile was 0.34 (0.13-0.89; P = 0.001 for trend). No significant associations were found for nephropathy. A MedDiet enriched with EVOO may protect against diabetic retinopathy but not diabetic nephropathy. © 2015 by the American Diabetes Association.

Epidemiologic evidence on long working hour and diabetes has been conflicting. We examined the association between overtime work and prevalence of diabetes among Japanese workers. The subjects were 40,861 employees (35,170 men and 5,691 women), aged 16 to 83 years, of 4 companies in Japan. Hours of overtime were assessed using self-reported questionnaires. Diabetes was defined as a fasting plasma glucose ≥126 mg/dl (7.0 mmol/l), hemoglobin A1c ≥6.5% (48 mmol/mol), or current use of anti-diabetic drug. Multiple logistic regression analysis was used to calculate odds ratio of diabetes for each category of overtime. After adjustment for age, sex, company, smoking, and BMI, there was a suggestion of U-shaped relationship between overtime work and prevalence of diabetes (P for quadratic trend = 0.07). Compared with those who worked <45 hours of overtime per month, the adjusted odds ratios (95% confidence interval) of diabetes were 0.86 (0.77-0.94), 0.69 (0.53-0.89), and 1.03 (0.72-1.46) for those who worked 45-79, 80-99, and ≥100 hours of overtime per month, respectively. In one company (n = 33,807), where other potential confounders including shift work, job position, type of department, alcohol consumption, sleep duration, leisure time physical activity, and family history of diabetes was additionally adjusted for, similar result was obtained (P for quadratic trend = 0.05). Long hours of overtime work may not be associated with increased prevalence of diabetes among Japanese workers.

To test the hypothesis that scores of a validated measure of physician empathy are associated with clinical outcomes for patients with diabetes mellitus. This retrospective correlational study included 20,961 patients with type 1 or type 2 diabetes mellitus from a population of 284,298 adult patients in the Local Health Authority, Parma, Italy, enrolled with one of 242 primary care physicians for the entire year of 2009. Participating physicians' Jefferson Scale of Empathy scores were compared with occurrence of acute metabolic complications (hyperosmolar state, diabetic ketoacidosis, coma) in diabetes patients hospitalized in 2009. Patients of physicians with high empathy scores, compared with patients of physicians with moderate and low empathy scores, had a significantly lower rate of acute metabolic complications (4.0, 7.1, and 6.5 per 1,000 patients, respectively, P < .05). Logistic regression analysis showed physicians' empathy scores were associated with acute metabolic complications: odds ratio (OR) = 0.59 (95% confidence interval [CI], 0.37-0.95, contrasting physicians with high and low empathy scores). Patients' age (≥69 years) also contributed to the prediction of acute metabolic complications: OR = 1.7 (95% CI, 1.2-1.4). Physicians' gender and age, patients' gender, type of practice (solo, association), geographical location of practice (mountain, hills, plain), and length of time the patient had been enrolled with the physician were not associated with acute metabolic complications. These results suggest that physician empathy is significantly associated with clinical outcome for patients with diabetes mellitus and should be considered an important component of clinical competence.

We aimed to examine the effects of bariatric surgery on microvascular complications in patients with type 2 diabetes using objective measures. Prospective case-control study of 70 obese surgical patients with type 2 diabetes undergoing gastric bypass surgery matched for age, sex and duration of diabetes to 25 medical patients treated using international guidelines. Microvascular complications were assessed before and 12-18 months after intervention using urine albumin creatinine ratio (ACR) measurements, two-field digital retinal images and peripheral nerve conduction studies (in the surgical group only). Urine ACR decreased significantly in the surgical group but increased in the medical group. There were no significant differences between the surgical and medical groups in the changes in retinopathy. There were no changes in the nerve conduction variables in the surgical group. In the short term, bariatric surgery may be superior to medical care in the treatment of diabetic nephropathy, but not retinopathy or neuropathy.

We are currently facing several attempts aimed at marketing genetic data for predicting multifactorial diseases, among which diabetes mellitus is one of the more prevalent. The present document primarily aims at providing to practicing physicians a summary of available data regarding the role of genetic information in predicting diabetes and its chronic complications. Firstly, general information about characteristics and performance of risk prediction tools will be presented in order to help clinicians to get acquainted with basic methodological information related to the subject at issue. Then, as far as type 1 diabetes is concerned, available data indicate that genetic information and counseling may be useful only in families with many affected individuals. However, since no disease prevention is possible, the utility of predicting this form of diabetes is at question. In the case of type 2 diabetes, available data really question the utility of adding genetic information on top of well performing, easy available and inexpensive non-genetic markers. Finally, the possibility of using the few available genetic data on diabetic complications for improving our ability to predict them will also be presented and discussed. For cardiovascular complication, the addition of genetic information to models based on clinical features does not translate in a substantial improvement in risk discrimination. For all other diabetic complications genetic information are currently very poor and cannot, therefore, be used for improving risk stratification. In all, nowadays the use of genetic testing for predicting diabetes and its chronic complications is definitively of little value in clinical practice.

Diabetic complications, and in particular diabetic foot ulcers (DFUs), are associated with low health-related quality of life (HRQoL). We evaluated whether the presence of diabetic complications also influenced the improvement of HRQoL during DFU treatment. 1088 patients presenting for DFU treatment at the centers participating in the Eurodiale study were followed prospectively up to one year. HRQoL was measured both at presentation and after healing or at end of follow up, using EQ-5D: a standardized instrument consisting of five domains and a summary index. The influence of diabetic comorbidity on the course of HRQoL was evaluated for each of the EQ-5D outcomes in multi-level linear regression analyses, adjusting for baseline characteristics. HRQoL improved in all EQ-5D outcomes over the course of treatment for those DFUs that healed. The few significant differences in the development of HRQoL between patients with and without comorbidity showed a more beneficial development for patients with comorbidity in DFUs that did not heal or healed slowly. Comorbidity does not hamper improvement of HRQoL in DFU treatment. On the contrary, HRQoL improved sometimes more in patients with certain comorbidity with hard-to-heal ulcers.

Diabetes mellitus (DM) has reached pandemic status and shows no signs of abatement. It can severely impair people's quality of life and affects patients all over the world. Since it is a serious, chronic metabolic disease, it can bring about many kinds of complications, which can in turn increase mortality. In recent decades, more and more studies have shown that oxidative stress and inflammatory reactions play critical roles in the pathogenesis of DM. There is an increasing demand for natural antidiabetic medicines that do not have the same side effects as modern drugs. Curcumin, a phytochemical found in the spice turmeric, has been used in India for centuries, and it has no known side effects. It has been shown to have some beneficial effects against various chronic illnesses. Many of these therapeutic actions can be attributed to its potent anti-oxidant and anti-inflammatory activities. In view of the oxidative stress and inflammatory mechanisms of DM, curcumin can be considered suitable for the prevention and amelioration of diabetes. In this review, we summarize the nosogenesis of DM, giving primary focus to oxidative stress and inflammation. We discuss the anti-oxidant and anti-inflammatory activities of curcumin in DM and its ability to mitigate the effects on DM and its associated complications in detail.

Objectives To determine risk factors for and long-term effects of glycemic control on urinary incontinence among women with type 1 diabetes enrolled in the Epidemiology of Diabetes Interventions and Complications (EDIC) study. Methods The Diabetes Control and Complications Trial (1982 to 1993) cohort follow-up, EDIC, began in 1994. In 2004, women participants (N=550), completed a self-administered questionnaire on incontinence. Our primary outcome was ≥ weekly incontinence, overall and by type. Multivariable regression models were used to determine independent predictors of weekly UI, both overall and by type. Results Overall, 38% of women reported any incontinence and 17% reported ≥ weekly incontinence. Increasing body mass index (Odds Ratio (OR) 1.1 per kg/m2, 95% Confidence Interval (CI) 1.1−1.2) was significantly associated with weekly incontinence, overall and by type. Advancing age and two or more urinary tract infections in the prior year were associated with weekly urge incontinence (OR 1.4, 95% CI 1.0−2.0 per 5 years; OR 4.9, 95% CI 1.8−13.5, respectively). There was weaker evidence for increased risk with age for overall weekly incontinence (22% per 5 years, p=0.06) and stress incontinence (21 % per 5 years, p=0.08) Conclusions Urinary incontinence is common among women with type 1 diabetes and risk factors including advancing age, increased weight, and prior urinary tract infection are important. Weight reduction and treatment of urinary tract infections may have the additional benefit of preventing incontinence or reducing its severity. PMID:19362350

There are no reports of very long follow-up studies of pregnant women with type 2 diabetes after delivery. Here we describe cases of Japanese women whom we treated for 20 to 50 years after deliveries to investigate the relationship between blood glucose control and diabetic complications. In Japan, the prevalence of type 1 diabetes is very low, and we have very few long-term follow-up cases with type 1 diabetes. Therefore, we chose to describe subjects with type 2 diabetes only. We present data on a total of 80 deliveries, 68 cases, treated by one of us (Y.O.) for more than a 50-year period. They are divided into 4 groups based on duration of treatment after delivery: more than 50 years (1 delivery, 1 patient), 40 to 49 years (13 deliveries, 11 patients), 30 to 39 years (19 deliveries, 16 patients), and 20 to 29 years (47 deliveries, 40 patients). Their present average ages in these 4 groups are 77, 72.4, 65.9, and 55.5 years, respectively. Their average HbA1c levels at last visit, in May 2014, are 8.2%, 7.6%.,7.2%, and 8.3%, respectively. Despite elevated HbA1c levels, they had relatively few complications: 40% (no retinopathy), 43.8% (simple retinopathy), and 12.5% (treated with photocoagulation); 67.5% (no albuminuria), 26.3% (albuminuria), and 6.3% (treated with renal transplantation or hemodialysis). Therefore, even if glycemic control is not ideal, nonstop treatment of Japanese women for type 2 diabetes after deliveries is effective to prevent diabetic complications. Long-term attention to care of diabetes after pregnancy may be preventive of diabetic complications in other populations as well. Copyright © 2016 John Wiley & Sons, Ltd.

This study aimed to develop a risk stratification strategy for evaluating the relationship between complications of diabetes and the risk of diabetic-related hospitalization to accurately classify diabetes severity. The study used administrative health records for 40,624 individuals with diabetes aged ≥18years in Western Australian. The adapted Diabetes Complication Severity Index (DCSI), socio-demographic and clinical characteristics were used in random effects negative binomial and threshold effect models to determine the optimal stratification strategy for diabetes severity based on the homogeneity of the risk of hospitalization in response to variation of the DCSI. The optimal stratification of people with diabetes was specified by four sub-populations. The first sub-population was no complications with an inverse association with the risk of hospitalizations (coefficient-0.247, SE 0.03). Further three sub-populations with DCSI at one (coefficient 0.289, SE 0.01), two (coefficient 0.339, SE 0.01) and three or more (coefficient 0.381, SE 0.01) were used to accurately describe the impact of DCSI on the risk of hospitalization. A stratification into four subpopulations based on the homogeneous impact of diabetes DCSI on the risk of hospitalization may be more suitable for evaluating health care interventions and planning health care provision.

Japanese diets contain a relatively high amount of carbohydrates, and its high dietary glycemic index and glycemic load may raise the risk of diabetes in the Japanese population. The current study evaluated the associations between the dietary glycemic index, glycemic load, and the risk of type 2 diabetes in a population based cohort in Japan. We observed 27,769 men and 36,864 women (45-75 y) who participated in the second survey of the Japan Public Health Center-based Prospective Study. The dietary glycemic index and glycemic load were estimated using a food-frequency questionnaire. The development of diabetes was reported in a questionnaire administered five years later, and the associations were analyzed using logistic regression after controlling for age, area, total energy intake, smoking status, family history of diabetes, physical activity, hypertension, BMI, alcohol intake, magnesium, calcium, dietary fiber and coffee intake, and occupation. The dietary glycemic load was positively associated with the risk of diabetes among women: the multivariable-adjusted odds ratio comparing the highest vs. the lowest quartile was 1.52 (95% CI, 1.13-2.04; P-trend = 0.01). The association was implied to be stronger among women with BMI < 25 than the women with BMI ≥ 25. The dietary glycemic index was positively associated with the risk of diabetes among men with a high intake of total fat: the multivariable-adjusted odds ratio comparing the highest vs. the lowest quartile was 1.46 (95% CI, 0.94-2.28; P-trend = 0.04). Among women with a high total fat intake, those in the first and second quartiles of the dietary glycemic index had a significant reduced risk of diabetes, compared with those in the first quartile who had a lower total fat level (multivariable-adjusted odds ratio = 0.59 with 95% CI, 0.37-0.94, and odds ratio = 0.63 with 95% CI, 0.40-0.998 respectively). The population-based cohort study in Japan indicated that diets with a high

Epidemiological studies carried out on a large sample (3191 elderly and 640 centenarians) with identical criteria and applying the actual diagnostic standards, have evidenced a high, statistically significant prevalence of diabetes mellitus type 2 (DMT2) (18.84%) in the elderly, as compared to the centenarians (7.50%). This aspect is correlated with the major frequency of maturity onset diabetes in elderly (MODE), compared to the centenarians, correlated also to the mortality of diabetes mellitus (DM) of long duration. The DMT2 and the aging interact in the determinism of vascular alterations, i.e., of the hypertension, and related cardio-cerebrovascular complications. The most frequently occurring hypertension in both the elderly and centenarians was always the systolic-isolated one. The prevalence of hypertension and acute myocardial infarction (AMI) was statistically significantly higher in diabetics, compared to the normoglycemic patients, in both the elderly and the centenarians. In addition, in a group of 914 elderly patients, being diabetics or normoglycemic at the start of the studies, but having neither AMI nor stroke at the baseline studies, after 5 years, these complications were more prevalent, significantly in statistical terms, in the diabetic subjects, compared to the normoglycemic ones. The increase of life-span causes an increase of the age when the aging phenomena appear, resulting in that the equal-age elderly people today are of better clinical conditions, compared to the previous periods. The increased life span with a consequent progressive aging of the population causes a worse general clinical state of the elderly population, characterized by polypathologies, frailty, and appearance of cognitive deficits or incapabilities for performing manual or instrumental activities.

Mechanisms of metabolic memory and renal hypoxia as a therapeutic target in diabetic kidney disease.

PubMed

Hirakawa, Yosuke; Tanaka, Tetsuhiro; Nangaku, Masaomi

2017-05-01

Diabetic kidney disease (DKD) is a worldwide public health problem. The definition of DKD is under discussion. Although the term DKD was originally defined as 'kidney disease specific to diabetes,' DKD frequently means chronic kidney disease with diabetes mellitus and includes not only classical diabetic nephropathy, but also kidney dysfunction as a result of nephrosclerosis and other causes. Metabolic memory plays a crucial role in the progression of various complications of diabetes, including DKD. The mechanisms of metabolic memory in DKD are supposed to include advanced glycation end-products, deoxyribonucleic acid methylation, histone modifications and non-coding ribonucleic acid including micro ribonucleic acid. Regardless of the presence of diabetes mellitus, the final common pathway in chronic kidney disease is chronic kidney hypoxia, which influences epigenetic processes, including deoxyribonucleic acid methylation, histone modification, and conformational changes in micro ribonucleic acid and chromatin. Therefore, hypoxia and oxidative stress are appropriate targets of therapies against DKD. Prolyl hydroxylase domain inhibitor enhances the defensive mechanisms against hypoxia. Bardoxolone methyl protects against oxidative stress, and can even reverse impaired renal function; a phase 2 trial with considerable attention to heart complications is currently ongoing in Japan. © 2017 The Authors.

The aim of the study was to determine the feasibility, and to evaluate the effect of, a cardiovascular self-management support program by applying the 5A's self-management support program on preventing cardiovascular complication behaviors and to assess the clinical outcomes in the elderly with poorly controlled type 2 diabetes mellitus (DM). This pilot study used a quasi-experimental study design. Twelve elderly persons with poorly controlled type 2 DM were assigned into either a control or experimental group, with six participants in each group. The Preventing Cardiovascular Complication Behaviors (PCCB) was measured by the Preventing Cardiovascular Complication Behaviors Questionnaire, while the clinical outcomes were measured by clinical devices that were provided. These measurements were conducted and compared at baseline and 6 weeks after the completion of the program. The self-management support program was a 6 week program with several implementation methods, based on the 5A's self-management support program. The participants who received the cardiovascular self-management support program reported a significant improvement in their PCCB and clinical outcomes, compared to those receiving the usual care. This study revealed that a cardiovascular self-management support program that applies the 5A's self-management support program is feasible for implementation. © 2018 Japan Academy of Nursing Science.

Oxidative Stress and NLRP3-Inflammasome Activity as Significant Drivers of Diabetic Cardiovascular Complications: Therapeutic Implications

It is now increasingly appreciated that inflammation is not limited to the control of pathogens by the host, but rather that sterile inflammation which occurs in the absence of viral or bacterial pathogens, accompanies numerous disease states, none more so than the complications that arise as a result of hyperglycaemia. Individuals with type 1 or type 2 diabetes mellitus (T1D, T2D) are at increased risk of developing cardiac and vascular complications. Glucose and blood pressure lowering therapies have not stopped the advance of these morbidities that often lead to fatal heart attacks and/or stroke. A unifying mechanism of hyperglycemia-induced cellular damage was initially proposed to link elevated blood glucose levels with oxidative stress and the dysregulation of metabolic pathways. Pre-clinical evidence has, in most cases, supported this notion. However, therapeutic strategies to lessen oxidative stress in clinical trials has not proved efficacious, most likely due to indiscriminate targeting by antioxidants such as vitamins. Recent evidence now suggests that oxidative stress is a major driver of inflammation and vice versa, with the latest findings suggesting not only a key role for inflammatory pathways underpinning metabolic and haemodynamic dysfunction in diabetes, but furthermore that these perturbations are driven by activation of the NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome. This review will address these latest findings with an aim of highlighting the interconnectivity between oxidative stress, NLRP3 activation and inflammation as it pertains to cardiac and vascular injury sustained by diabetes. Current therapeutic strategies to lessen both oxidative stress and inflammation will be emphasized. This will be placed in the context of improving the burden of these diabetic complications.

Long-term effects of lifestyle intervention or metformin on diabetes development and microvascular complications over 15-year follow-up: the Diabetes Prevention Program Outcomes Study.

PubMed

2015-11-01

Effective prevention is needed to combat the worldwide epidemic of type 2 diabetes. We investigated the long-term extent of beneficial effects of lifestyle intervention and metformin on diabetes prevention, originally shown during the 3-year Diabetes Prevention Program (DPP), and assessed whether these interventions reduced diabetes-associated microvascular complications. The DPP (1996-2001) was a randomised trial comparing an intensive lifestyle intervention or masked metformin with placebo in a cohort selected to be at very high risk of developing diabetes. All participants were offered lifestyle training at the end of the DPP. 2776 (88%) of the surviving DPP cohort were followed up in the DPP Outcomes Study (DPPOS, Sept 1, 2002, to Jan 2, 2014) and analysed by intention to treat on the basis of their original DPP assignment. During DPPOS, the original lifestyle intervention group was offered lifestyle reinforcement semi-annually and the metformin group received unmasked metformin. The primary outcomes were the development of diabetes and the prevalence of microvascular disease. For the assessment of microvascular disease, we used an aggregate microvascular outcome, composed of nephropathy, retinopathy, and neuropathy. During a mean follow-up of 15 years, diabetes incidence was reduced by 27% in the lifestyle intervention group (hazard ratio 0·73, 95% CI 0·65-0·83; p<0·0001) and by 18% in the metformin group (0·82, 0·72-0·93; p=0·001), compared with the placebo group, with declining between-group differences over time. At year 15, the cumulative incidences of diabetes were 55% in the lifestyle group, 56% in the metformin group, and 62% in the placebo group. The prevalences at the end of the study of the aggregate microvascular outcome were not significantly different between the treatment groups in the total cohort (placebo 12·4%, 95% CI 11·1-13·8; metformin 13·0%, 11·7-14·5; lifestyle intervention 11·3%, 10·1-12·7).

The GERODIAB study is a multicenter prospective observational study performed over 5 years in French patients aged 70 years or above with type 2 diabetes. This report deals with their cardiovascular complications and their relationship with survival. Consecutive patients ( n = 987, median age = 77 years) were included from 56 diabetes centers over 1 year. Individual characteristics, history and complications of diabetes, geriatric factors, and clinical and biological parameters were recorded. Survival was analyzed using the Kaplan-Meier method and proportional hazards regression models. The frequency of cardiovascular complications increased from 47% at inclusion to 67% at 5 years. The most frequent complications were coronary heart disease (increasing from 30% to 41%) and vascular disease of the lower limbs (25% to 35%) and of the cerebral vessels (15% to 26%). Heart failure was less common, but its frequency doubled during the follow-up (9% to 20%). It was strongly associated with poor survival ( P < 0.0001), as was vascular disease of the lower limbs ( P = 0.0004), whereas coronary heart disease ( P = 0.0056) and vascular disease of cerebral vessels ( P = 0.026) had mild associations. Amputation ( P < 0.0001) and foot wounds ( P < 0.0001) were strongly associated with survival. In multivariate models, heart failure was the strongest predictor of poor survival (hazard ratio [HR] 1.96 [95% CI 1.45-2.64]; P < 0.0001). It remained significant when other factors were considered simultaneously (HR 1.92 [95% CI 1.43-2.58]; P < 0.0001). Cardiovascular complications are associated with poor survival in elderly patients with type 2 diabetes, especially heart failure. © 2017 by the American Diabetes Association.

To determine the impact of an integrated diabetes service involving specialist outreach and primary health care teams on risk factors for micro- and macrovascular diabetes complications in three remote Indigenous Australian communities over a 12-month period. Quantitative, retrospective evaluation. Primary health care clinics in remote Indigenous communities in Australia. One-hundred-and-twenty-four adults (including 123 Indigenous Australians; 76.6% female) with diabetes living in remote communities. Glycosylated haemoglobin, lipid profile, estimated glomerular filtration rate, urinary albumin : creatinine ratio and blood pressure. Diabetes prevalence in the three communities was high, at 32.8%. A total of 124 patients reviewed by the outreach service had a median consultation rate of 1.0 by an endocrinologist and 0.9 by a diabetes nurse educator over the 12-month period. Diabetes care plans were made in collaboration with local primary health care services, which also provided patients with diabetes care between outreach team visits. A significant reduction was seen in median (interquartile range) glycosylated haemoglobin from baseline to 12 months. Median (interquartile range) total cholesterol was also reduced. The number of patients prescribed glucagon-like peptide-1 analogues and dipeptidyl peptidase-4 inhibitors increased over the 12 months and an increase in the number of patients prescribed insulin trended towards statistical significance. A collaborative health care approach to deliver diabetes care to remote Indigenous Australian communities was associated with an improvement in glycosylated haemoglobin and total cholesterol, both important risk factors, respectively, for micro- and macrovascular diabetes complications. © 2018 National Rural Health Alliance Ltd.

Objective: To determine the association of educational status (ES), as marker of socioeconomic status, with the prevalence of microvascular complications in diabetes. Methods: Successive patients (n = 1214) presenting to our center were evaluated for sociodemographic, anthropometric, clinical, and therapeutic variables. Subjects were classified according to ES into Group 1 (illiterate, 216); Group 2 (≤ primary, 537), Group 3 (≤ higher secondary, 312), and Group 4 (any college, 149). Descriptive statistics is reported. Results: Mean age of patients was 52 ± 10 years, duration of diabetes 7 ± 7 years and 55% were men. Prevalence of various risk factors was smoking/tobacco 25.5%, obesity body mass index ≥25 kg/m2 64.0%, abdominal obesity 63.4%, hypertension 67.5%, high fat diet 14.5%, low fruits/vegetables 31.8%, low fiber intake 60.0%, high salt diet 16.9%, physical inactivity 27.5%, coronary or cerebrovascular disease 3.0%, and microvascular disease (peripheral, ocular or renal) in 20.7%. Microvascular disease was significantly greater in illiterate (25.9%) and low (23.6%) compared to middle (15.0%) and high (14.7%) ES groups (P < 0.05). Age- and sex-adjusted logistic regression analysis revealed that in illiterate and low ES groups respectively, prevalence of smoking/tobacco use (odds ratio 3.84, confidence interval: 09–7.05 and 2.15, 1.36–3.41); low fruit/vegetable (2.51, 1.53–4.14 and 1.99, 1.30–3.04) and low fiber intake (4.02, 2.50–6.45 and 1.78, 1.23–2.59) was greater compared to high ES. Poor diabetes control (HbA1c >.0%) was significantly greater in illiterate (38.0%), low (46.0%), and middle (41.0%) compared to high (31.5%) ES subjects (P < 0.05). Conclusions: There is a greater prevalence of the microvascular disease in illiterate and low ES diabetes patients in India. This is associated with the higher prevalence of smoking/tobacco use, poor quality diet, and sub-optimal diabetes control. PMID:26693427

Objective Epidemiologic evidence on long working hour and diabetes has been conflicting. We examined the association between overtime work and prevalence of diabetes among Japanese workers. Methods The subjects were 40,861 employees (35,170 men and 5,691 women), aged 16 to 83 years, of 4 companies in Japan. Hours of overtime were assessed using self-reported questionnaires. Diabetes was defined as a fasting plasma glucose ≥126 mg/dl (7.0 mmol/l), hemoglobin A1c ≥6.5% (48 mmol/mol), or current use of anti-diabetic drug. Multiple logistic regression analysis was used to calculate odds ratio of diabetes for each category of overtime. Results After adjustment for age, sex, company, smoking, and BMI, there was a suggestion of U-shaped relationship between overtime work and prevalence of diabetes (P for quadratic trend = 0.07). Compared with those who worked <45 hours of overtime per month, the adjusted odds ratios (95% confidence interval) of diabetes were 0.86 (0.77–0.94), 0.69 (0.53–0.89), and 1.03 (0.72–1.46) for those who worked 45–79, 80–99, and ≥100 hours of overtime per month, respectively. In one company (n = 33,807), where other potential confounders including shift work, job position, type of department, alcohol consumption, sleep duration, leisure time physical activity, and family history of diabetes was additionally adjusted for, similar result was obtained (P for quadratic trend = 0.05). Conclusions Long hours of overtime work may not be associated with increased prevalence of diabetes among Japanese workers. PMID:24787995

Because diabetes mellitus (DM) is a multifactorial metabolic disease, its prevention and treatment has been a constant challenge for basic and clinical investigators focused on translating their discoveries into clinical treatment of this complex disorder. In this review, we highlight recent experimental and clinical evidences of potential coadjuvants in the management of DM, such as polyphenols (quercetin, resveratrol and silymarin), cultured probiotic microorganisms and drugs acting through direct/indirect or pleiotropic effects on glycemic control in DM. Among several options, we highlight new promising therapeutic coadjuvants, including chemical scavengers, the probiotic kefir and the phosphodiesterase 5 inhibitors, which besides the reduction of hyperglycemia and ameliorate insulin resistance, they reduce oxidative stress and improve endothelial dysfunction in the systemic vascular circulation. In the near future, experimental studies are expected to clear the intracellular pathways involving coadjuvants. The design of clinical trials may also contribute to new strategies with coadjuvants against the harmful effects of diabetic complications. PMID:27527163

In diabetes, angiogenesis is disturbed, contributing to proliferative retinopathy, nephropathy and neuropathy. Kallistatin, a serine proteinase inhibitor, has anti-angiogenic effects. We assessed serum kallistatin in children and adolescents with type 1 diabetes as a potential marker for microvascular complications and its relation to carotid intima media thickness (CIMT). Sixty patients with type 1 diabetes were divided into two groups according to the presence of microvascular complications and compared with 30 healthy controls. High-sensitivity C-reactive protein (hs-CRP), HbA1c, urinary albumin creatinine ratio (UACR), kallistatin levels and CIMT were assessed. Kallistatin levels were significantly higher in patients with microvascular complications (9.9 ± 2.38 ng/mL) and those without complications (5.0 ± 1.5 ng/mL) than in healthy controls (1.39 ± 0.55 ng/mL; p<0.001). Kallistatin was increased in patients with microalbuminuria compared with the normoalbuminuric group (p<0.001). Positive correlations were found between kallistatin and disease duration, fasting blood glucose, HbA1c, triglycerides, total cholesterol, hs-CRP, UACR and CIMT (p<0.05). A kallistatin cut-off value at 6.1 ng/mL could differentiate patients with and without microvascular complications, with a sensitivity of 96.87% and specificity of 93.75%. Increased kallistatin levels in type 1 diabetes and its relation with CIMT may reflect vascular dysfunction and suggest a link between micro- and macro-angiopathy. © The Author(s) 2015.

Disturbances in carbohydrate metabolism during pregnancy may result in harmful fetal and neonatal consequences. To assess the fetal and neonatal complications of pregnancy in mothers with gestational and pregestational diabetes during a 10-year period in a county hospital in Hungary. Retrospective analysis of infants of diabetic mothers admitted to the neonatal unit between 2001 and 2010. 32% of the infants were transferred to the neonatal unit. Neonatal macrosomia (birth weight >90 centile) was observed in one quarter of the infants. 39% of the infants developed hypoglycemia (blood glucose <2.6 mmol/l), in the majority of the cases within the first 8 hours. Hypoglycaemia was symptomatic in 55% of the infants. Hypocalcemia was observed in 17%, hyperviscosity in 23%, hyperbilirubinaemia in 32%, respiratory distress syndrome and/or transient tachypnoe in 22% and cardiac complications in 13% of the infants. 10% of the inafnts were affected with birth injuries. Congenital anomalies were seen in 17% of the cases, and severe malformations were present in 4% of the infants. Despite modern diabetes management, there is still a higher incidence of fetal macrosomia, adverse neonatal outcomes and a higher rate of severe congenital malformations in neonates of diabetic mothers.

Diabetes mellitus and hypertension diseases are frequently found in the same patient, which if untreated predispose to atherosclerotic and kidney diseases. The objective of this study was to identify potential biomarkers in the urine of diabetic and hypertensive patients through dispersive near-infrared Raman spectroscopy. Urine samples were collected from patients with diabetes and hypertension but no complications (LG), high degree of complications (HG), and control ones: one fraction was submitted to biochemical tests and another one was stored frozen (-20°C) until spectral analysis. Samples were warmed up and placed in an aluminum sample holder for Raman spectra collection using a dispersive spectrometer (830 nm wavelength, 300 mW laser power and 20 s exposure time). Spectra were then submitted to Principal Components Analysis. The PCA loading vectors 1 and 3 revealed spectral features of urea/creatinine and glucose, respectively; the PCA scores showed that patients with diabetes/hypertension (LG and HG) had higher amount of glucose in the urine compared to the normal group (p < 0.05), which can bring serious consequences to patients. Also, the PCA scores showed that the amount of urea decreased in the groups with diabetes/hypertension (p < 0.05), which generates the same concern as it is a marker that has a strong importance in the metabolic changes induced by such diseases. These results, applied to the analysis of urine of patients with diabetes/hypertension, can lead to early diagnostic information of complications and a possible disease prognosis in the patients where no complications from diabetes and hypertension were found.
