Abstract
Diabetes mellitus (DM) is the fifth-leading cause of death worldwide and contributes to leading causes of death, cancer and cardiovascular disease, including CAD, stroke, peripheral vascular disease, and other vascular disease. While glycemic management remains a cornerstone of DM care, the co-management of hypertension, atherosclerosis, cardiovascular risk reduction, and prevention of long-term consequences associated with DM are now well recognized as essential to improve long-term survival. Clinical trial evidence substantiates the importance of glycemic control, low-density cholesterol-lowering therapy, blood pressure lowering, control of albuminuria, and comprehensive approaches targeting multiple risk factors to reduce cardiovascular risk. This article presents a review of the role of DM in the pathogenesis of atherosclerosis and cardiac dysfunction, recent evidence on the degree of glycemic control and mortality, and available evidence for a multifaceted approach to improve long-term outcomes for patients.

LDL-cholesterol target values and actual values in patients with type 2 diabetes (T2D) uncontrolled on oral antidiabetic monotherapy: the lipid results of the French ESCALADE survey. ANNALES D'ENDOCRINOLOGIE 2012; 73:503-9. [PMID: 23122577 DOI: 10.1016/j.ando.2012.09.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/01/2012] [Accepted: 09/10/2012] [Indexed: 10/27/2022]
Abstract
AIM While new European guidelines have recommended much lower LDL-c target values than current 2005 French HAS guidelines, it appears that even those ones are not widely implemented. This lipid-side of the ESCALADE study was designed to determine the LDL-c target values of GPs, diabetologists (DIABs) and cardiologists (CARDIOs) and the consistency of actual values in patients with type 2 diabetes (T2D) uncontrolled on antidiabetic monotherapy. METHODS ESCALADE was a national multicentre, observational, descriptive, transversal survey. One thousand and three hundred GPs and 350 specialists (DIABs and CARDIOs) agreed to include respectively three and four patients each. For each patient, the physician had to set the LDL-c target value that was compared to the calculated HAS target value. The actual LDL-c value was recorded and compared to those target values. RESULTS A total of 412 GPs, 137 DIABs and 27 CARDIOs included respectively 699, 364 and 66 patients. Among them 19.6% had cardiovascular disease (CVD) and 56.9% were on lipid-lowering therapy (LLT). The physician's target value was in concordance with HAS value in 37.3% (GPs), 35.4% (DIABs) and 57.4% (CARDIOs) of the cases. Physicians overestimated the risk in respectively 42.7%, 54.1% and 21.3%. However, very high risk was underestimated in respectively 38.1%, 22.0% and 25.6% of the patients and the actual LDL-c value was in the target range (<100mg/dL) for only 28% of the very high-risk patients. CONCLUSION Physicians tend to overestimate the CVD risk in patients with T2D and set lower LDL-c target values than HAS calculated values. Nevertheless, patients with a very high risk are largely under-treated.

Abstract
Diabetes mellitus (DM) and congestive heart failure (HF) commonly coexist in the same patient, and the presence of DM in HF patients is associated with increased adverse events compared with patients without DM. Recent guidelines regarding glycemic control stress individualization of glycemic therapy based on patient comorbid conditions and potential adverse effects of medical therapy. This balance in glycemic control may be particularly relevant in patients with DM and HF. In this review, we address data regarding the influence that certain HF medications may have on glycemic control. Despite potential modest changes in glycemic control, clinical benefits of proven pharmacologic HF therapies extend to patients with DM and HF. In addition, we review potential benefits and challenges associated with commonly used glycemic medications in HF patients. Finally, recent data and controversies on optimal glycemic targets in HF patients are discussed. Given the large number of patients with DM and HF and the health burden of these conditions, much needed future work is necessary to define the optimal glycemic treatment in HF patients with DM.

Abstract
CONTEXT Ayurveda propounds that diseases manifest from imbalance of doshas. There, have been attempts to indicate biochemical basis of constitutional types described in Ayurveda. AIMS The study was intended to assess the association of constitutional types (Prakriti) with cardiovascular risk factors, inflammatory markers and insulin resistance in subjects with coronary artery disease (CAD). SETTINGS AND DESIGN Hospital based cross sectional study. MATERIALS AND METHODS Three hundred patients with CAD >25 years were studied. Assessment of Prakriti was done by using Ayusoft software. Biochemical parameters, inflammatory markers (hsCRP, TNF-alpha and IL-6) and insulin resistance (HOMA-IR) were measured. STATISTICAL ANALYSIS Was done using EPI INFO, version 3.5.3. RESULTS Mean age of patients was 60.97±12.5 years. Triglyceride, VLDL and LDL was significantly higher (P<0.0001, P<0.0001 and 0.0355, respectively) and HDL cholesterol (P<0.0001) significantly lower in vatta kapha (VK) Prakriti when compared with other constitution type. VK Prakriti was correlated with diabetes mellitus (r=0.169, P=0.003), hypertension (r=0.211, P≤0.0001) and dyslipidemia (r=0.541, P≤0.0001). Inflammatory markers; IL6, TNF alpha, hsCRP and HOMA IR was highest in VK Prakriti. Inflammatory markers were correlated positively with both VK and Kapha group. CONCLUSIONS There is strong relation of risk factors (diabetes, hypertension, dyslipidemia), insulin resistance, and inflammatory markers with Vata Kapha and Kapha Prakriti.

Abstract
OBJECTIVE To compare the performance of two glomerular filtration rate (GFR)-estimating equations in predicting the risk of all-cause and cardiovascular mortality in type 2 diabetic patients. RESEARCH DESIGN AND METHODS We followed 2,823 type 2 diabetic outpatients for a period of 6 years for the occurrence of all-cause and cardiovascular mortality. GFR was estimated using the four-variable Modification of Diet in Renal Disease (MDRD) study equation and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. RESULTS At baseline, an estimated GFR (eGFR) <60 mL/min/1.73 m(2) was present in 22.0 and 20.2% of patients using the MDRD study equation and the CKD-EPI equation, respectively. A total of 309 patients died during the follow-up (152 patients from cardiovascular causes). Both creatinine-based equations were associated with an increased risk of all-cause and cardiovascular mortality. However, the CKD-EPI equation provided a more accurate risk prediction of mortality than the MDRD study equation. Receiving operating characteristic curves showed that the areas under the curve (AUCs) for all-cause mortality (AUC 0.712 [95% CI 0.682-0.741]) and cardiovascular mortality (0.771 [0.734-0.808]) using eGFR(CKD-EPI) were significantly greater (P < 0.0001 by the z statistic) than those obtained by using eGFR(MDRD) (0.679 [0.647-0.711] for all-cause mortality and 0.739 [0.698-0.783] for cardiovascular mortality). CONCLUSIONS Our findings suggest that the estimation of GFR using the CKD-EPI equation more appropriately stratifies patients with type 2 diabetes according to the risk of all-cause and cardiovascular mortality compared with the MDRD study equation.

Abstract
BACKGROUND There is a need for reliable methods of glucose measurement in different environmental conditions. The objective of this in vitro study was to evaluate the performance of the Enlite® Sensor when connected to either the iPro™ Continuous Glucose Monitor recording device or the Guardian® REAL-Time transmitting device, in hypobaric and hyperbaric conditions. METHODS Sixteen sensors connected to eight iPro devices and eight Guardian REAL-Time devices were immersed in three beakers containing separate glucose concentrations: 52, 88, and 207 mg/dl (2.9, 4.9, and 11.3 mmol/liter). Two different pressure tests were conducted: a hypobaric test, corresponding to maximum 18000 ft/5500 m height, and a hyperbaric test, corresponding to maximum 100 ft/30 m depth. The linearity of the sensor signals in the different conditions was evaluated. RESULTS The sensors worked continuously, and the sensor signals were collected without interruption at all pressures tested. When comparing the input signals for glucose (ISIGs) and the different glucose concentrations during altered pressure, linearity (R(2)) of 0.98 was found. During the hypobaric test, significant differences (p < .005) were seen when comparing the ISIGs during varying pressure at two of the glucose concentrations (52 and 207 mg/dl), whereas no difference was seen at the 88 mg/dl glucose concentration. During the hyperbaric test, no differences were found. CONCLUSIONS The Enlite Sensors connected to either the iPro or the Guardian REAL-Time device provided values continuously. In hyperbaric conditions, no significant differences were seen during changes in ambient pressure; however, during hypobaric conditions, the ISIG was significantly different in the low and high glucose concentrations.

Abstract
Current treatment of diabetes in pregnancy relies on intermittent self-monitoring of blood glucoses using finger sticks to monitor capillary blood glucoses. Continuous glucose monitoring (CGM) systems are an emerging technology that allow frequent glucose measurements (every 5 min) and the ability to monitor glucose trends in real time. Although these devices are currently expensive and mildly invasive to use, there is huge potential for their use in both the research and clinical realms. From a research perspective, there is the potential to better understand glucose metabolism in pregnancy, both in patients with and without diabetes. For the treating clinician, CGM has the potential to improve detection of hyperglycemic excursions as well as asymptomatic hypoglycemia and the data to improve management of glucose levels in diabetes patients. In this article, we review current literature examining use of CGM in both research and clinical applications.

Abstract
INTRODUCTION To identify reasons why primary care physicians (PCPs) do not treat older patients newly diagnosed with type 2 diabetes mellitus (T2DM) with antihyperglycemic agents following diagnosis. METHODS US PCPs were surveyed via the internet regarding their reasons for not treating patients aged >65 years diagnosed with T2DM and had not yet initiated antihyperglycemic therapy for ≥6 months after diagnosis. PCPs were requested to provide relevant clinical information for untreated older patients and select applicable reasons for not initiating treatment from a list of 35 possibilities, grouped into five categories. RESULTS A total of 508 PCPs completed the online survey and provided complete clinical data for 770 patients. The reasons provided by the first-ranked physician for not initiating antihyperglycemic therapy were related to diet and exercise (57.5%); mild hyperglycemia (23.8%); patient's concerns (13.4%); concerns about antihyperglycemic agents (3.0%); and comorbidities and polypharmacy (2.3%). The "diet and exercise" category was the most common first-ranked non-treatment reason, regardless of recent hemoglobin A(1c) (HbA(1c)) stratum. Reasons within the "patient's concerns," "concerns related to antihyperglycemic agents," and "comorbidities and polypharmacy" categories tended to be selected more often as first-ranked reasons by physicians for patients with higher HbA(1c) values. Of the 158 patients whose physicians planned to initiate antihyperglycemic therapy within the next month, 54.4% already had a most recent HbA(1c) value above their physician-stated threshold for treatment initiation. CONCLUSION In the PCPs studied, there was a tendency to select appropriate reasons for non-treatment with antihyperglycemic agents given their patients' glycemic status. However, there was inertia related to the initiation of pharmacological therapy in some older patients with newly diagnosed T2DM. Important factors included physicians' perceptions of "mild" hyperglycemia and the HbA(1c) threshold for using antihyperglycemic agents.

Abstract
OBJECTIVE Because of the increasing incidence and prevalence of diabetes as a leading cause of end-stage renal disease (ESRD) in the aging population, we estimated the expected life-years (LYs) saved from successful prevention of ESRD in elderly patients with diabetes. RESEARCH DESIGN AND METHODS We conducted a population-based cohort study using the National Health Insurance Research Database. We identified all incidences of ESRD in the individuals >65 years of age who were receiving maintenance hemodialysis (N = 24,243) from the registry files of catastrophic illnesses in Taiwan from 1 July 1997 to 31 December 2005. We then retrospectively searched the database to determine whether there had been a diagnosis of diabetes in these cases. After the exclusion of individuals with malignancy (n = 3,423), we extrapolated the survival rates through the end of 2006 using the Monte Carlo method. Using the data of preventable ESRD cases due to diabetes and expected years of life lost (EYLL) in each age stratum, we further estimated the expected LYs saved from successful prevention of ESRD in elderly patients with diabetes. RESULTS The estimated average EYLL was 10.6-5.8 and 12.3-7.3 years for diabetic males and females, respectively, aged 65-79 years. In total, 5,430.1 LYs and 10,177 LYs could be saved by the successful prevention of ESRD in male and female elderly patients with diabetes, respectively, in a single year. CONCLUSIONS The LYs saved by successful prevention of ESRD in elderly patients with diabetes in a single year are substantial and deserve special attention, especially in elderly females.

Abstract
Studies documenting the effectiveness of medical nutrition therapy for Type 1 and Type 2 diabetes report improvements in hemoglobin A1C (A1C), as well as in other outcomes. A variety of nutrition therapy interventions are effective. Under debate is the role of carbohydrate intake on glycemic control and weight loss in individuals with Type 2 diabetes. Some studies have reported improvements in glycemic control from reducing carbohydrate intake; however, other trials have reported no significant changes in A1C with a lower carbohydrate eating pattern. Studies comparing low-carbohydrate or low-fat diets for weight loss at 12 months report similar amounts of weight loss. Evidence for the usefulness of the glycemic index concept is debatable. For the majority of people with diabetes moderate alcohol consumption with food will have minimal, if any, acute or long-term effects on glycemic control, and may have beneficial effects on insulin sensitivity and decreased risk for coronary heart disease.

Abstract
Diabetes has emerged as a disease of major public health importance in India affecting the rich and the poor alike. Conventionally, comprehensive diabetes management is aimed at preventing micro and macro vascular complications. However, morbidity and mortality due to infections are also significant. In developing countries like India, the concept of adult immunization is far from reality. Recently the H1N1 pandemic has triggered the necessity for considering immunization in all age groups for the prevention of vaccine-preventable fatal infectious diseases. Considering the economics of immunization in a developing country, providing free vaccines to all adults may not be a practical solution, although the free universal immunization program for children is in existence for several decades. There is no consensus on the use of vaccines in diabetes subjects in India. However, there are some clinics offering routine pneumococcal, influenza and other vaccinations. Patients with diabetes have a deranged immune system making them more prone for infections. Hospitalization and death due to pneumococcal disease and influenza are higher in diabetes patients. They, like other healthy individuals, have a normal humoral response to vaccination with clinically significant benefits. The American Diabetes Association, Advisory Committee on Immunization Practices, Centers for Disease Control and Prevention, World Health Organization, United Kingdom Guidelines and a number of other scientific organizations have well defined guidelines for vaccination in diabetes. In this article we make some suggestions for clinicians in India, regarding use of vaccines in subjects with diabetes.

Abstract
AIMS Care management may improve the quality of diabetes care by enhancing contact between high-risk patients and their providers. This prospective, longitudinal, randomized trial sought to investigate whether telephone or online care management improves diabetes-related outcomes over time compared with usual care supplemented with Internet access and training. SUBJECTS AND METHODS One hundred fifty-one adult subjects with type 2 diabetes mellitus and an elevated hemoglobin A1c (A1c) level (≥8.5%) were randomly assigned to online care management (n=51), telephone-based care management (n=51), or Web training (n=49) groups. Online and telephone participants interacted with a care manager through a diabetes education and care management Web site and by telephone, respectively. The Web training group was provided with online diabetes self-management resources but no care management support. The primary outcome measure was A1c measured every 3 months for a year. RESULTS A1c declined significantly and substantially in all groups over 12 months. A1c declined linearly at a rate of 0.32% (P<0.0001) per quarter for the online group, 0.36% (P<0.0001) for the telephone group, and 0.41% for the Web training group (P<0.0001). The rate of change over time did not differ significantly among groups. The groups converged at 12 months with average absolute A1c difference of -1.5%. The number of interactions with care providers was not significantly associated with the change in A1c. Blood pressure, weight, lipid levels, and diabetes distress did not differ among groups over time. CONCLUSIONS Online, telephone-based care management, and Web training for diabetes patients with elevated A1c were each associated with a substantial improvement in A1c over a 1-year period. Internet access and training alone may be as effective as care management in patients with poorly controlled diabetes.

Abstract
BACKGROUND The purpose of this study was to design and evaluate a safety system for the artificial pancreas device system (APDS). Safe operation of the APDS is a critical task, where the safety system is engaged only as needed to ensure reliable operation without positive feedback to the controller. METHODS The Health Monitoring System (HMS) was designed as a modular system to ensure the safety of the APDS and the user. It was designed using a large set of ambulatory data and evaluated in silico by inducing hypoglycemia with a missed meal [bolus for a 65 g carbohydrate (CHO) meal] and administering rescue CHOs per HMS alerting. The HMS was validated in-clinic with a real-life challenge of a subject who overdosed insulin prior to admission. RESULTS The HMS was evaluated for clinical use with a 15 min prediction horizon. Retrospectively, 93.5% of episodes were detected with 2.9 false alarms per day. During in silico evaluation, the HMS reduced the time spent <70 mg/dl from 15% to 3%. When the HMS was first tested in-clinic, the subject overdosed ~3 U of insulin prior to her arrival to a closed-loop session (against protocol). The controller reduced insulin delivery, and the HMS gave four alerts that were successfully received via clinical software and text and multimedia messages. Even with insulin reduction and CHO supplements, hypoglycemia was unavoidable but manageable due to the HMS, confirming that a safety system to detect adverse events is an essential part of the APDS. CONCLUSIONS The ability of the HMS to be an effective alert system that provides a safety layer to the APDS controller has been demonstrated in a clinical setting.

Abstract
While pharmacists have long been delivering personalized clinical patient services, recognition of pharmacists as health care providers, realization of the value of pharmacist cognitive services, and fair payment for pharmacists have been slow to evolve. This article tracks the evolution of medication therapy management (MTM) services provided by pharmacists, using the Medicare Modernization Act of 2003 as a springboard. The core elements of MTM services are discussed and reviewed, and MTM programs and services as outlined in the Medicare Part D outpatient prescription drug benefit are thoroughly examined. Pharmacist and patient perceptions of the value of MTM are outlined, and barriers to MTM implementation at the pharmacy/pharmacist level are evaluated. Key studies showing the economic and clinical benefits of MTM services are discussed, as well as important drivers that may propel MTM beyond the Medicare Part D threshold.

Abstract
OBJECTIVE To detect clinical correlates of cognitive abilities and white matter (WM) microstructural changes using diffusion tensor imaging (DTI) in young children with type 1 diabetes. RESEARCH DESIGN AND METHODS Children, ages 3 to <10 years, with type 1 diabetes (n = 22) and age- and sex-matched healthy control subjects (n = 14) completed neurocognitive testing and DTI scans. RESULTS Compared with healthy controls, children with type 1 diabetes had lower axial diffusivity (AD) values (P = 0.046) in the temporal and parietal lobe regions. There were no significant differences between groups in fractional anisotropy and radial diffusivity (RD). Within the diabetes group, there was a significant, positive correlation between time-weighted HbA(1c) and RD (P = 0.028). A higher, time-weighted HbA(1c) value was significantly correlated with lower overall intellectual functioning measured by the full-scale intelligence quotient (P = 0.03). CONCLUSIONS Children with type 1 diabetes had significantly different WM structure (as measured by AD) when compared with controls. In addition, WM structural differences (as measured by RD) were significantly correlated with their HbA(1c) values. Additional studies are needed to determine if WM microstructural differences in young children with type 1 diabetes predict future neurocognitive outcome.

Abstract
Cardiorenal metabolic syndrome (CRS) is a global health care concern in view of aging in certain populations, increased obesity, changing lifestyles, and its close association with type 2 diabetes mellitus and cardiovascular morbidity and mortality. Determining the appropriate criteria for CRS has been somewhat controversial, and efforts to fully describe and define the syndrome are still ongoing. Nonetheless, improving knowledge of the syndrome among health care professionals will help to identify patients who may require pharmacological and therapeutic lifestyle intervention, particularly with regards to addressing high-normal blood pressure and hypertension. This article reviews current clinical guidelines with a focus on the identification, especially in racial/ethnic minorities, treatment, and associated cardiovascular morbidity and mortality of high blood pressure and hypertension in patients with CRS. Efficacy and outcomes studies that provide insight into the selection of an initial antihypertensive regimen in this population will be discussed. Finally, a brief review of the benefits of olmesartan medoxomil and combination therapy and patient factors in the management of hypertension with CRS will be addressed.

Abstract
BACKGROUND/PURPOSE The impact of the introduction of newer anti-diabetic agents on the treatment pattern in the booming diabetic population remains unclear. We examined the patterns and temporal trends of anti-diabetic drug use in Taiwan, with particular emphasis on combination therapy. METHODS We searched the Taiwan National Health Insurance Database during 2000-2009 to identify outpatient prescriptions of anti-diabetic drugs, including human insulins and insulin analogues, sulfonylureas, glinides, metformin, thiazolidinediones, alpha-glucosidase inhibitors, and dipeptidyl peptidase-4 inhibitors. Glucose-lowering treatments were classified according to pattern (oral agents only, insulins only, and oral agents and insulins combined) and a number of different classes of anti-diabetic drugs. Insulin therapy and combination therapy with two oral anti-diabetic drugs (OAD) were further classified according to individual drug combination patterns. RESULTS Although metformin remained the mainstay of anti-diabetic treatment, patients receiving combination therapy of oral glucose-lowering agents, either with or without insulin, significantly increased, from approximately 40% in 2000 to 60% in 2009, particularly in relation to the newer agents, including glinides, alpha-glucosidase inhibitors, and long-acting insulin analogues. Use of sulfonylureas and thiazolidinediones decreased substantially. For insulin therapy, the most commonly prescribed drugs were premix insulin analogues and basal insulin analogues, accounting for one-third of total insulin prescriptions in 2009. CONCLUSION We found an increasing complexity of anti-diabetic therapy during the past decade in Taiwan. Further studies are needed to evaluate whether this treatment pattern will lead to improved clinical outcomes in terms of cost-effectiveness.

Abstract
BACKGROUND Given the increasing prevalence of diabetes and the lack of patients reaching recommended therapeutic goals, novel models of team-based care are emerging. These teams typically include a combination of physicians, nurses, case managers, pharmacists, and community-based peer health promoters (HPs). Recent evidence supports the role of pharmacists in diabetes management to improve glycemic control, as they offer expertise in medication management with the ability to collaboratively intensify therapy. However, few studies of pharmacy-based models of care have focused on low income, minority populations that are most in need of intervention. Alternatively, HP interventions have focused largely upon low income minority groups, addressing their unique psychosocial and environmental challenges in diabetes self-care. This study will evaluate the impact of HPs as a complement to pharmacist management in a randomized controlled trial. METHODS/DESIGN The primary aim of this randomized trial is to evaluate the effectiveness of clinical pharmacists and HPs on diabetes behaviors (including healthy eating, physical activity, and medication adherence), hemoglobin A1c, blood pressure, and LDL-cholesterol levels. A total of 300 minority patients with uncontrolled diabetes from the University of Illinois Medical Center ambulatory network in Chicago will be randomized to either pharmacist management alone, or pharmacist management plus HP support. After one year, the pharmacist-only group will be intensified by the addition of HP support and maintenance will be assessed by phasing out HP support from the pharmacist plus HP group (crossover design). Outcomes will be evaluated at baseline, 6, 12, and 24 months. In addition, program and healthcare utilization data will be incorporated into cost and cost-effectiveness evaluations of pharmacist management with and without HP support. DISCUSSION The study will evaluate an innovative, integrated approach to chronic disease management in minorities with poorly controlled diabetes. The approach is comprised of clinic-based pharmacists and community-based health promoters collaborating together. They will target patient-level factors (e.g., lack of adherence to lifestyle modification and medications) and provider-level factors (e.g., clinical inertia) that contribute to poor clinical outcomes in diabetes. Importantly, the study design and analytic approach will help determine the differential and combined impact of adherence to lifestyle changes, medication, and intensification on clinical outcomes.

Abstract
Cardiovascular disease remains a leading cause of death in the United States and the world. In this we will paper focus on type 2 diabetes mellitus as a risk factor for coronary heart disease, review the mechanisms of atherogenesis in diabetics, the impact of hypertension and the treatment goals in diabetics, the guidelines for screening, and review the epidemiologic consequences of diabetes and heart disease on a global scale. The underlying premise to consider diabetes a cardiovascular disease equivalent will be explored as well as the recommendations for screening and cardiac testing for asymptomatic diabetic patients.

Abstract
BACKGROUND We tested the concordance of the two diagnostic criteria for diabetes using fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) by the Japan Diabetes Society (JDS) and American Diabetes Association (ADA). METHODS We used data from 7,328 subjects without known diabetes who participated in a voluntary health checkup program at least twice between 1998 and 2006, at intervals ≤ 2 years. For repeat participants who attended the screening over two times, data from the first and second checkups were used for this study. At the first visit, diabetes was diagnosed both at FPG ≥ 7.0 mmol/L and HbA1c ≥ 6.5% using the JDS criteria. In addition, diabetes was diagnosed using two ADA criteria; ADA-FPG diabetes for persistent fasting hyperglycemia (FPG ≥ 7.0 mmol/L) or ADA-HbA1c diabetes for hyper-glycated hemoglominemia (HbA1c ≥ 6.5%), both at the first and second checkups. Subsequently, the concordance of diagnosis between the JDS and the ADA criteria was evaluated. RESULTS At the first checkup, 153 (2.1%) persons were diagnosed with diabetes by the JDS criteria. They had higher levels of risk factors for diabetes than non-diabetic subjects. Using the first and second checkups, 174 (2.4%) and 175 (2.4%) were diagnosed with diabetes by the ADA-FPG criteria, respectively. Among 153 subjects diagnosed with diabetes by the JDS criteria, 125 (81.7%) and 129 (84.3%) had ADA-FPG and ADA-HbA1c diabetes, respectively. The kappa coefficients of the JDS criteria with ADA-FPG and ADA-HbA1c criteria were 0.759 and 0.782 (P<0.001), respectively. In the subgroup analysis stratified by sex, the concordance was well preserved at the kappa coefficients around 0.8 (between 0.725 and 0.836). CONCLUSION The JDS diagnostic criteria for diabetes have a substantial and acceptable concordance with the ADA criteria. The JDS criteria may be a practical method for diagnosing diabetes that maintains compatibility with the ADA criteria.

Abstract
Aims/Introduction. To describe patterns of long-term glycemic control among patients with type 2 diabetes in Isfahan, Iran and identify factors associated with glycemic control. Methods. During the mean (standard deviation (SD)) follow-up period of 8.4 (4.2) (range 1-18) years, 4,582 patients with type 2 diabetes have been examined to determine glycemic changes. Their glycated hemoglobin (GHb) at the last clinic visit was compared with the initial visit data. The mean (SD) age of participants was 49.3 (9.6) years with a mean (SD) duration of diabetes of 5.0 (5.1) years at initial registration. Results. Mean (SD) GHb was 8.7% (2.3) at baseline and 7.9% (1.9) at the study end and decreased by mean of 0.8% (95% confidence interval (CI) 0.74, 0.87; P < 0.001) and varied by the severity of baseline GHb. 74.6% at the initial visit versus 64.4% at the last clinic visit had GHb values above the target level of 7.0%. Using a stepwise multiple regression models, age, higher GHb, FPG, follow-up period, and number of follow-up visits increased and higher systolic BP and female gender significantly decreased the percent glycemic change. Conclusions. This study highlights that more than 64.4% of the patients have GHb values higher than 7.0% at last clinic visit andindicatesthe difficult challenges physicians face when treating their patients with type 2 diabetes. Clinical efforts should focus on more effective methods for glycemic control in diabetic patients.

Abstract
Objective The metabolic syndrome (MetS) is a cluster of clinical indices that signals increased risk for cardiovascular disease and Type 2 diabetes. The diagnosis of MetS is typically based on cut-off points for various components, e.g. waist circumference and blood pressure. Because current MetS criteria result in racial/ethnic discrepancies, our goal was to use confirmatory factor analysis to delineate differential contributions to MetS by sub-group. Research Design and Methods Using 1999–2010 data from the National Health and Nutrition Examination Survey (NHANES), we performed a confirmatory factor analysis of a single MetS factor that allowed differential loadings across sex and race/ethnicity, resulting in a continuous MetS risk score that is sex and race/ethnicity-specific. Results Loadings to the MetS score differed by racial/ethnic and gender subgroup with respect to triglycerides and HDL-cholesterol. ROC-curve analysis revealed high area-under-the-curve concordance with MetS by traditional criteria (0.96), and with elevations in MetS-associated risk markers, including high-sensitivity C-reactive protein (0.71), uric acid (0.75) and fasting insulin (0.82). Using a cut off for this score derived from ROC-curve analysis, the MetS risk score exhibited increased sensitivity for predicting elevations in ≥2 of these risk markers as compared with traditional pediatric MetS criteria. Conclusions The equations from this sex- and race/ethnicity-specific analysis provide a clinically-accessible and interpretable continuous measure of MetS that can be used to identify children at higher risk for developing adult diseases related to MetS, who could then be targeted for intervention. These equations also provide a powerful new outcome for use in childhood obesity and MetS research.

Abstract
This study aimed to estimate the proportion of patients at the University Hospital of the West Indies (UHWI) Diabetes Clinic who engage in recommended foot care and footwear practices. Seventy-two participants from the UHWI Diabetes Clinic completed an interviewer-administered questionnaire on foot care practices and types of footwear worn. Participants were a subset of a sex-stratified random sample of clinic attendees and were interviewed in 2010. Data analysis included frequency estimates of the various foot care practices and types of footwear worn. Participants had a mean age of 57.0±14.3 years and mean duration of diabetes of 17.0±10.3 years. Fifty-three percent of participants reported being taught how to care for their feet, while daily foot inspection was performed by approximately 60% of participants. Most participants (90%) reported daily use of moisturizing lotion on the feet but almost 50% used lotion between the toes. Approximately 85% of participants reported wearing shoes or slippers both indoors and outdoors but over 40% reported walking barefoot at some time. Thirteen percent wore special shoes for diabetes while over 80% wore shoes without socks at some time. Although much larger proportions reported wearing broad round toe shoes (82%) or leather shoes (64%), fairly high proportions reported wearing pointed toe shoes (39%), and 43% of women wore high heel shoes. In conclusion, approximately 60% of patients at the UHWI diabetic clinic engage in daily foot inspection and other recommended practices, but fairly high proportions reported foot care or footwear choices that should be avoided.

Wermeling PR, Gorter KJ, van Stel HF, Rutten GEHM. Both cardiovascular and non-cardiovascular comorbidity are related to health status in well-controlled type 2 diabetes patients: a cross-sectional analysis. Cardiovasc Diabetol 2012; 11:121. [PMID: 23039172 PMCID: PMC3508839 DOI: 10.1186/1475-2840-11-121] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2012] [Accepted: 10/03/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Type 2 diabetes patients have a decreased health-related quality of life compared to healthy persons, especially regarding physical functioning and well-being. Health-related quality of life is even lower in type 2 diabetes patients when other diseases co-exist. In contrast to earlier studies, we assessed the associations between the number and type of comorbidities and health status in well-controlled type 2 diabetes patients, in whom treatment goals for HbA1c, blood pressure and cholesterol had been reached. Approximately one in five type 2 diabetes patients belongs to this group. METHODS Cross-sectional analysis was performed in 2086 well-controlled (HbA1c ≤58 mmol/mol, systolic blood pressure ≤145 mmHg, total cholesterol ≤5.2 mmol/l and not using insulin) type 2 diabetes patients in general practice. Both number and type (cardiovascular and non-cardiovascular) of comorbidities were determined for each patient. Health status was assessed with the questionnaires Short Form-36 (SF-36) and EuroQol (EQ). The SF-36 generates eight dimensions of health and a Physical and Mental Component Score (PCS and MCS), scale: 0-100. The EQ consists of two parts: EQ-5D and EQ Visual Analogue Scale. Multivariable linear regression analysis was used to assess if number and type of comorbidities were associated with health status. RESULTS Well-controlled type 2 diabetes patients with comorbidities had a much lower health status, with a decrease ranging from -1.5 for the MCS to -26.3 for role limitations due to physical problems, compared to those without. Health status decreased when the number of comorbidities increased, except for mental health, role limitations due to emotional problems, MCS and both EQ measures. In patients with both cardiovascular and non-cardiovascular comorbidity, physical functioning, role limitations due to physical problems and PCS were significantly lower than in patients with only cardiovascular comorbidity. Physical functioning was also lower compared to patients with only non-cardiovascular comorbidity. CONCLUSIONS Even acceptable values of HbA1c, blood pressure and cholesterol in type 2 diabetes patients are not necessarily related with a good health status. We have shown that comorbidities have a large impact on health status. Physicians may take into account patient's health status and integrate the impact of comorbidities into diabetes care.

Abstract
BACKGROUND Novel preventive care opportunities, such as in hospitalized patients, may merit further investigation in an Accountable Care Organization (ACO) model. As 40% of patients with diabetes are undiagnosed, diabetes screening is an urgent public health need. Screening fasting preoperative patients may present an effective means to identify patients who might otherwise remain undiagnosed. OBJECTIVE To pilot an inpatient preventive care strategy for diabetes screening that would ascertain prevalence of unrecognized inpatient diabetes (DM) and impaired fasting glucose (IFG), determine reproducibility of preoperative fasting blood glucose (FBG), and establish feasibility of inpatient preventive screening. DESIGN Prospective observational study. SETTING Large Midwestern academic medical center. PATIENTS Two hundred seventy-five elective orthopedic patients with a preoperative visit between December 1, 2007 and November 30, 2008. Most patients (96.6%) had seen their primary care provider (PCP) within 12 months, and 100% were insured. MEASUREMENTS Medical history was recorded, and hemoglobin A(1C) (Hgb A(1C) ) and FBG were drawn immediately prior to surgery. Patients with preoperative FBG ≥100 mg/dL had FBG drawn 6-8 weeks postoperatively. RESULTS Twenty-four percent (67/275) of patients had previously unrecognized DM or IFG by virtue of 2 abnormal values. Sixty-four percent of patients with FBG ≥100 mg/dL preoperatively remained elevated at ambulatory follow-up. No patients with new DM or IFG had point-of-care glucose checks ordered or had dysglycemia mentioned on discharge summary. CONCLUSIONS Inpatient undiagnosed DM and IFG is common, even in insured, elective surgery patients with recent primary care visits. Preoperative FBG can be used to screen, but results need to be conveyed to PCPs.

Abstract
In the near future, the majority of patients with diabetes will be adults aged 65 or older. Unlike young adults with diabetes, elderly diabetic people may be affected by a variety of comorbid conditions such as depression, cognitive impairment, muscle weakness (sarcopenia), falls and fractures, and physical frailty. These geriatric syndromes should be considered in the establishment of treatment goals in older adults with diabetes. Although there are several guidelines for the management of diabetes, only a few are specifically designed for the elderly with diabetes. In this review, we present specific conditions of elderly diabetes which should be taken into account in the management of diabetes in older adults. We also present advantages and disadvantages of various glucose-lowering agents that should be considered when choosing a proper regimen for older adults with diabetes.

Abstract
Despite the known benefits of a healthy lifestyle, many individuals find it hard to maintain such a lifestyle in our modern world, which facilitates sedentary behavior and overeating. As a consequence, the prevalence of type 2 diabetes mellitus is predicted to increase dramatically over the coming years. Will developments in treatments be able to counteract the resulting impact on morbidity and mortality? The various lines of research can be grouped into three main categories: technological, biological, and pharmacological. Technological solutions are focused on the delivery of insulin and glucagon via an artificial pancreas, and components of the system are already in use, suggesting this option may well be available within the next 10 years. Of the biological solutions, pancreas transplants seem unlikely to be used widely, and islet cell transplants have also been hampered by a lack of appropriate donor tissue and graft survival after transplant. However, significant progress has been made in these areas, and additional research suggests manipulating other cell types to replace beta cells may be a viable option in the longer term. The last category, pharmacological research, appears the most promising for significantly reducing the burden of type 2 diabetes mellitus. In recent years, research has concentrated on reducing blood glucose, and the increasing pace of research has been reflected in a growing number of antidiabetic agents. In the past few years, studies of the complementary approach of protecting cells from the damaging effects of high blood glucose have also been reported, as has research into the control of energy intake and energy expenditure. Evidence from studies of dietary restriction and bariatric surgery suggests it may be possible to reset metabolism to effectively cure diabetes, and research into pharmacological agents that could selectively restore energy balance is currently the most exciting prospect for future treatments for people with type 2 diabetes mellitus.

Abstract
Emerging adults with type 1 diabetes are at risk for poor glycemic control, gaps in medical care, and adverse health outcomes. With the increasing incidence in type 1 diabetes in the pediatric population, there will be an increase in the numbers of teens and young adults transferring their care from pediatric providers to adult diabetes services in the future. In recent years, the topic of transitioning pediatric patients with type 1 diabetes to adult diabetes care has been discussed at length in the literature and there have been many observational studies. However, there are few interventional studies and, to date, no randomized clinical trials. This paper discusses the rationale for studying this important area. We review both observational and interventional literature over the past several years, with a focus on new research. In addition, important areas for future research are outlined.

Abstract
Obesity is an important risk factor for type 2 diabetes mellitus (T2DM). Weight loss improves the major factors involved in the pathogenesis of T2DM, namely insulin action and beta cell function, and is considered a primary therapy for obese patients who have T2DM. Unfortunately, most patients with T2DM fail to achieve successful weight loss and adequate glycemic control from medical therapy. In contrast, bariatric surgery causes marked weight loss and complete remission of T2DM in most patients. Moreover, bariatric surgical procedures that divert nutrients away from the upper gastrointestinal tract are more successful in producing weight loss and remission of T2DM than those that simply restrict stomach capacity. Although upper gastrointestinal tract bypass procedures alter the metabolic response to meal ingestion, by increasing early postprandial plasma concentrations of glucagon-like peptide 1 and insulin, it is not clear whether these effects make an important contribution to long-term control of glycemia and T2DM once substantial surgery-induced weight loss has occurred. Nonetheless, the effects of surgery on body weight and metabolic function indicate that bariatric surgery should be part of the standard therapy for T2DM. More research is needed to advance our understanding of the physiological effects of different bariatric surgical procedures and possible weight loss-independent factors that improve metabolic function and contribute to the resolution of T2DM.

Abstract
Objective. Patient-reported outcomes (PROs) have become an essential part of the assessment of patients with rheumatoid arthritis (RA). We aimed to evaluate the agreement and correlation between PROs and the physician's measurements. Methods. This was a cross-sectional analytical study in which 135 patients with RA were clinically evaluated during two different sessions of focus group interviews. Rheumatologist recorded 28 swollen (SJCs) and tender joint counts (TJCs). The patients filled out the PROs instruments (MDHAQ, RADAI, RAPID3, 4, and 5 and self-report articular index (SAI) diagram for pain and joint swelling). DAS28 was calculated (C-reactive protein). An adjusted multiple lineal regression model was done (DAS28 as dependent variable). Results. Highly significant agreements were found between SJC and TJC registered by the physician and patient. There was moderate correlation between DAS28 with patient SJC (r = 0.52), patient TJC (r = 0.55), RADAI (r = 0.56), RAPID3 (r = 0.52), RAPID4 (r = 0.56), RAPID5 (r = 0.66), and VAS-Global (r = 0.51). Likewise, we found moderate to high correlations between CDAI and SDAI with all variable measurements done by the patients. The resulting predictive equation was DAS28(CRP) = 2.02 + 0.037 × RAPID4 + 0.042× patient SJC. Conclusion. PROs applied in focus groups interview are a useful tool for managing patients with RA regardless of gender, educational level, and duration of disease.

Abstract
Adipose tissue inflammation plays a role in cardiovascular (CV) and metabolic diseases associated with obesity, insulin resistance, and type 2 diabetes mellitus (T2DM). The interactive effects of exercise training and metformin, two first-line T2DM treatments, on adipose tissue inflammation are not known. Using the hyperphagic, obese, insulin-resistant Otsuka Long-Evans Tokushima Fatty (OLETF) rat model, we tested the hypothesis that treadmill training, metformin, or a combination of these reduces the secretion of proinflammatory cytokines from adipose tissue. Compared with Long-Evans Tokushima Otsuka (LETO) control rats (L-Sed), sedentary OLETF (O-Sed) animals secreted significantly greater amounts of leptin from retroperitoneal adipose tissue. Conversely, secretion of interleukin (IL)-10 by O-Sed adipose tissue was lower than that in L-Sed animals. Examination of leptin and IL-10 secretion from adipose tissue in OLETF groups treated with endurance exercise training (O-EndEx), metformin treatment (O-Met), and a combination of these (O-E+M) from 20 to 32 wk of age indicated that 1) leptin secretion from adipose tissue was reduced in O-Met and O-E+M, but not O-EndEx animals; 2) adipose tissue IL-10 secretion was increased in O-EndEx and O-E+M but not in O-Met animals; and 3) only the combined treatment (O-E+M) displayed both a reduction in leptin secretion and an increase in IL-10 secretion. Leptin and IL-10 concentrations in adipose tissue-conditioned buffers were correlated with their plasma concentrations, adipocyte diameters, and total adiposity. Overall, this study indicates that exercise training and metformin have additive influences on adipose tissue secretion and plasma concentrations of leptin and IL-10.

Abstract
PURPOSE The purpose of this study is to describe the development and implementation of a new diabetes prevention intervention that combines the benefits of family support with the group office model. Intensive lifestyle modification can effectively delay the onset of type 2 diabetes, yet health providers are challenged in translating these results to their patients. The group outpatient visit model can provide a means to address prevention issues in a financially sustainable manner. METHODS Materials from the Diabetes Prevention Program and a previously developed group office visit program were combined to create the Families United/Familias Unidas curriculum. The session content utilized a multiculturally tailored approach designed to help participants decrease portion size, decrease carbohydrate intake, increase physical activity, and increase resiliency. Adults aged 18 to 70 were recruited who had any diabetes risk factors but did not have diabetes. Eligible participants enlisted a support person, aged 14 to 70, to join them in the 6-month group office visit intervention. RESULTS Twenty-nine pairs (n = 58) of primary participants plus support persons were recruited. Participants' average age was 45; 74% were female; 56.9% identified themselves as white and 37.9% as Hispanic/Latino. Over one-third had 4 or more diabetes risk factors. Twelve family group office visits were delivered over 6 months. The attendance rate for those who attended at least one session was 72%. CONCLUSIONS Group office visits can provide a new sustainable model for diabetes prevention and are a natural fit for primary care physicians in collaboration with other health care professionals, such as dieticians or diabetes educators.

Abstract
OBJECTIVE While neuropathy is common in the elderly, nerve conduction (NC) reproducibility in older adults is not well-established. We sought to evaluate intraobserver reproducibility of peroneal motor NC measures in a diverse sample of older adults. METHODS We measured peroneal motor NC amplitude and velocity in a subset of participants (mean age=82.9±2.7, n=62, 50% female, 51.6% black, 35.5% DM) in the Health, Aging, and Body Composition Study. Using coefficients of variation (CVs), intraclass correlation coefficients (ICCs), and Bland Altman Plots, we compared two sets of measurements taken by the same examiner hours apart on the same day. RESULTS Low CVs (2.15-4.24%) and moderate to high ICCs (0.75-0.99) were observed. No systematic variation was found across measures. Despite small numbers in some subgroups, we found no differences in reproducibility by diabetes, race or study site. CONCLUSION NC measures have moderate to high intraobsever reproducibility in older adults and are not affected by diabetes, race, or gender. SIGNIFICANCE These data provide evidence to support use of these measures in aging research.

Abstract
PURPOSE The purpose of this study was to explore potential factors affecting the self-management behaviors of Korean immigrants with type 2 diabetes mellitus (KIT2Ds). METHODS A qualitative descriptive design guided this study. Semistructured interviews lasting 45 to 60 minutes were conducted with 20 KIT2Ds in the participants' preferred language; in all cases, this was Korean. Each interview was audiotaped, transcribed, and analyzed using conventional content analysis. Data analysis was performed in two steps. The data written in Korean were initially analyzed by 3 bilingual researchers. A qualitative researcher then participated in the analysis to refine the findings for presentation to an English-speaking audience while staying true to the data and preserving the nuanced Korean meanings. RESULTS The mean age of the sample was 64. 5 ± 11.6 years (9 men and 11 women). The mean years of staying in the United States and age at diabetes mellitus diagnosis were 23.6 ± 9.7 years and 52.5 ± 12.3 years, respectively. Three major ideas were identified: (1) issues on treatment regimen related to medications and diet, (2) resources that helped or hindered ability to manage diabetes, and (3) the physician-patient relationship. CONCLUSIONS Important cultural nuances need to be addressed to better prepare KIT2Ds to manage their diabetes more effectively. A culture-specific program should extend beyond a diabetes self-management education delivered in Korean language. Rather, content and education methods need to consider acculturation effects on diabetes management behaviors.

Abstract
BACKGROUND Whether hypoglycemia leads to death in critically ill patients is unclear. METHODS We examined the associations between moderate and severe hypoglycemia (blood glucose, 41 to 70 mg per deciliter [2.3 to 3.9 mmol per liter] and ≤40 mg per deciliter [2.2 mmol per liter], respectively) and death among 6026 critically ill patients in intensive care units (ICUs). Patients were randomly assigned to intensive or conventional glucose control. We used Cox regression analysis with adjustment for treatment assignment and for baseline and postrandomization covariates. RESULTS Follow-up data were available for 6026 patients: 2714 (45.0%) had moderate hypoglycemia, 2237 of whom (82.4%) were in the intensive-control group (i.e., 74.2% of the 3013 patients in the group), and 223 patients (3.7%) had severe hypoglycemia, 208 of whom (93.3%) were in the intensive-control group (i.e., 6.9% of the patients in this group). Of the 3089 patients who did not have hypoglycemia, 726 (23.5%) died, as compared with 774 of the 2714 with moderate hypoglycemia (28.5%) and 79 of the 223 with severe hypoglycemia (35.4%). The adjusted hazard ratios for death among patients with moderate or severe hypoglycemia, as compared with those without hypoglycemia, were 1.41 (95% confidence interval [CI], 1.21 to 1.62; P<0.001) and 2.10 (95% CI, 1.59 to 2.77; P<0.001), respectively. The association with death was increased among patients who had moderate hypoglycemia on more than 1 day (>1 day vs. 1 day, P=0.01), those who died from distributive (vasodilated) shock (P<0.001), and those who had severe hypoglycemia in the absence of insulin treatment (hazard ratio, 3.84; 95% CI, 2.37 to 6.23; P<0.001). CONCLUSIONS In critically ill patients, intensive glucose control leads to moderate and severe hypoglycemia, both of which are associated with an increased risk of death. The association exhibits a dose-response relationship and is strongest for death from distributive shock. However, these data cannot prove a causal relationship.

STUDY DESIGN Part of an intervention with 130 patients with type 2 diabetes, this observational study further looked at PA in 19 physician-patient dyads. Data Collection. Observations occurred in a teaching hospital, which served as recruiting and study site. PRINCIPAL FINDINGS PA correlated with knowledge, self-efficacy, promotion orientation, and exercise intent. Patient-reported PA did not correlate with researcher-observed or physician-reported PA behavior. Researcher-observed PA correlated with physician-observation items. CONCLUSIONS Results provide evidence for measuring different perspectives in studies of PA. When patients report they are activated in self-management, behavior does not indicate they are active in clinical communication, a critical component of collaborative decision making.

Abstract
BACKGROUND Early detection to identify people at risk of diabetes is an important approach to prevent or delay type 2 diabetes. This study aimed to implement the Diabetes Prevention Program in community pharmacy using a diabetes risk prediction tool. METHODS The program was conducted in seven pharmacies in Bangkok, Thailand. Participants were the pharmacy's clients aged ≥ 35 years without the history of diabetes. A validated risk prediction tool was used to assess individuals' diabetes risk. Educational information was offered to all participants. Those with a high risk score (≥ 9 out of 17) were offered a self-check of fasting capillary blood glucose (CBG). A referral was made for those with CBG ≥ 126 mg/dl. RESULTS During a 3-month service, 397 individuals participated in the program. Nearly half of the participants (49.4%) were at a high risk of diabetes (risk score: ≥ 9). Ninety five (48.5%) of these high risk individuals undertook fasting CBG. Elevated fasting CBG (≥ 126 mg/dl) was found in 12 persons (12.7%). Overall, two patients with diabetes were identified during the provision of the program. CONCLUSIONS The Diabetes Prevention Program in community pharmacies uncovered half of the clients who were at risk of diabetes and provided an opportunity for participants to learn more about the prevention of diabetes.

Abstract
UNLABELLED BACKGROUND The association between serum alanine aminotransferase (ALT) levels and hepatic insulin resistance (IR) has been evaluated with the hyperinsulinemic-euglycemic clamp. However, there is no information about the association of ALT with the Hepatic Insulin Resistance Index (HIRI). The aim of this study was to evaluate the association between serum ALT levels and HIRI in subjects with differing degrees of impaired glucose metabolism. METHODS This cross-sectional study included subjects that had an indication for testing for type 2 diabetes mellitus (T2DM) with an oral glucose tolerance test (OGTT). Clinical and biochemical evaluations were carried out including serum ALT level quantification. HIRI was calculated for each participant. Correlation analyses and lineal regression models were used to evaluate the association between ALT levels and HIRI. RESULTS A total of 324 subjects (37.6% male) were included. The mean age was 40.4 ± 14.3 years and the mean body mass index (BMI) was 32.0 ± 7.3 kg/m2. Individuals were divided into 1 of 5 groups: without metabolic abnormalities (n = 113, 34.8%); with the metabolic syndrome (MetS, n = 179, 55.2%), impaired fasting glucose (IFG, n = 85, 26.2%); impaired glucose tolerance (IGT, n = 91, 28.0%), and T2DM (n = 23, 7.0%). The ALT (p < 0.001) and HOMA2-IR (p < 0.001) values progressively increased with HIRI quartiles, while ISI-Matsuda (p < 0.001) progressively decreased. After adjustment for sex, age, and BMI, we identified a significant correlation between HIRI and ALT in persons with the MetS (r = 0.22, p = 0.003), IFG (r = 0.33, p < 0.001), IGT (r = 0.37, p < 0.001), and T2DM (r = 0.72, p < 0.001). Lineal regression analysis adjusting for age, HDL-C, TG and waist circumference (WC) showed an independent association between ALT and HIRI in subjects with the MetS (beta = 0.07, p = 0.01), IFG (beta = 0.10, p = 0.02), IGT (beta = 0.09, p = 0.007), and T2DM (beta = 0.31, p = 0.003). This association was not identified in subjects without metabolic abnormalities. CONCLUSIONS ALT levels are independently associated with HIRI in subjects with the MetS, IFG, IGT, and T2DM. The ALT value in these subjects may be an indirect parameter to evaluate hepatic IR.

Prediction of cardiovascular events, diabetic nephropathy, and mortality by albumin concentration in a spot urine sample in patients with type 2 diabetes. J Diabetes Complications 2012; 26:407-12. [PMID: 22677793 DOI: 10.1016/j.jdiacomp.2012.04.014] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2011] [Revised: 04/21/2012] [Accepted: 04/23/2012] [Indexed: 11/16/2022]
Abstract
AIMS To analyze in a random urine spot the predictive value of urinary albumin concentration (UAC) for cardiovascular events, diabetic nephropathy (DN), and death in patients with type 2 diabetes. METHODS In this cohort, urinary albumin (immunoturbidimetry) was measured as 24-h urinary albumin excretion (UAE) and, in a random spot urine, as UAC and albumin:creatinine ratio (ACR). Primary outcomes were: 1) cardiovascular events, 2) DN defined as a composite outcome [macroalbuminuria and/or decreased glomerular filtration rate (GFR) <60 ml/min/1.73 m²], and 3) death. RESULTS A total of 199 type 2 diabetic patients, aged 59.9 ± 9.9 years, were followed for 6.1 ± 2.7 years. UAC ≥14.4 mg/l, as determined by ROC curve, predicted DN and prediction for this and other outcomes were compared with traditional microalbuminuria cutoffs for ACR and UAE. The outcomes frequency was: cardiovascular events = 26.4%, DN = 31.7% (23.5% decreased GFR; 13.6% macroalbuminuria) and death = 8.50%. In Cox analyses, UAC ≥14 mg/l increased the risk (hazard ratio, HR) for cardiovascular events 3.25 times (95% CI 1.43-7.38; P = 0.005), 4.30 for DN composite outcome (95% CI 2.22-8.32; P <0.001), and 5.51 for death (95% CI 1.16-26.22; P = 0.032). Corresponding HRs of ACR ≥30 mg/g were: 2.89 (95% CI 1.29-6.45; P = 0.009) for cardiovascular events, 4.67 (95% CI 2.34-9.34; P <0.001) for DN composite outcome and 5.07 (95% CI 1.01-24.88; P = 0.049) for death. HRs of UAE ≥30 mg/24-h were: 2.20 (95% CI 2.08-2.49; P = 0.030) for cardiovascular events, 6.76 (95% CI 3.32-13.77; P <0.001) for DN composite outcome, and 2.47 (95% CI 0.72-8.42; P = 0.150) for death. CONCLUSIONS In conclusion, random UAC ≥14 mg/l predicted cardiovascular events, diabetic nephropathy, and mortality just as well as ACR. UAC may be used to assess cardiovascular and renal risks in patients with type 2 diabetes.

Abstract
OBJECTIVE The aim was to provide a scholarly review of the published literature on biological, clinical, and nonclinical contributors to race/ethnic and sex disparities in endocrine disorders and to identify current gaps in knowledge as a focus for future research needs. PARTICIPANTS IN DEVELOPMENT OF SCIENTIFIC STATEMENT: The Endocrine Society's Scientific Statement Task Force (SSTF) selected the leader of the statement development group (S.H.G.). She selected an eight-member writing group with expertise in endocrinology and health disparities, which was approved by the Society. All discussions regarding the scientific statement content occurred via teleconference or written correspondence. No funding was provided to any expert or peer reviewer, and all participants volunteered their time to prepare this Scientific Statement. EVIDENCE The primary sources of data on global disease prevalence are from the World Health Organization. A comprehensive literature search of PubMed identified U.S. population-based studies. Search strategies combining Medical Subject Headings terms and keyword terms and phrases defined two concepts: 1) racial, ethnic, and sex differences including specific populations; and 2) the specific endocrine disorder or condition. The search identified systematic reviews, meta-analyses, large cohort and population-based studies, and original studies focusing on the prevalence and determinants of disparities in endocrine disorders. consensus process: The writing group focused on population differences in the highly prevalent endocrine diseases of type 2 diabetes mellitus and related conditions (prediabetes and diabetic complications), gestational diabetes, metabolic syndrome with a focus on obesity and dyslipidemia, thyroid disorders, osteoporosis, and vitamin D deficiency. Authors reviewed and synthesized evidence in their areas of expertise. The final statement incorporated responses to several levels of review: 1) comments of the SSTF and the Advocacy and Public Outreach Core Committee; and 2) suggestions offered by the Council and members of The Endocrine Society. CONCLUSIONS Several themes emerged in the statement, including a need for basic science, population-based, translational and health services studies to explore underlying mechanisms contributing to endocrine health disparities. Compared to non-Hispanic whites, non-Hispanic blacks have worse outcomes and higher mortality from certain disorders despite having a lower (e.g. macrovascular complications of diabetes mellitus and osteoporotic fractures) or similar (e.g. thyroid cancer) incidence of these disorders. Obesity is an important contributor to diabetes risk in minority populations and to sex disparities in thyroid cancer, suggesting that population interventions targeting weight loss may favorably impact a number of endocrine disorders. There are important implications regarding the definition of obesity in different race/ethnic groups, including potential underestimation of disease risk in Asian-Americans and overestimation in non-Hispanic black women. Ethnic-specific cut-points for central obesity should be determined so that clinicians can adequately assess metabolic risk. There is little evidence that genetic differences contribute significantly to race/ethnic disparities in the endocrine disorders examined. Multilevel interventions have reduced disparities in diabetes care, and these successes can be modeled to design similar interventions for other endocrine diseases.

Abstract
BACKGROUND Patients with diabetes who use insulin pumps [continuous subcutaneous insulin infusion (CSII)] undergo surgeries that require postoperative hospital admission. There are no defined guidelines for CSII perioperative use. METHODS This retrospective single-institution study identified type 1 and type 2 diabetes subjects by electronically searching 2005-2010 anesthesia preoperative assessments for "pump." Surgical cases (n = 92) were grouped according to intraoperative insulin delivery method: (a) CSII continuation of basal rate with/without correctional insulin bolus(es) (n = 53); (b) conversion to intravenous insulin infusion (n = 20); and (c) CSII suspension with/without correctional insulin bolus(es) (n = 19). These groups were compared on mean intraoperative blood glucose (BG) and category of most extreme intraoperative BG. RESULTS Differences were found on baseline characteristics of diabetes duration (p = .010), anesthesia time (p = .011), proportions receiving general anesthesia (p = .013), and preoperative BG (p = .033). The conversion group had the longest diabetes duration and anesthesia time; it had a higher proportion of general anesthesia recipients and a higher mean preoperative BG than the continuation group. There was no significant difference in mean BG/surgical case between continuation (163.5 ± 58.5 mg/dl), conversion (152.3 ± 28.9 mg/dl), and suspension groups (188.3 ± 44.9 mg/dl; p = .128). The suspension group experienced a greater percentage of cases (84.2%) with one or more intraoperative BG > 179 mg/dl than continuation (45.3%) and conversion (40%) groups Figure 1 groupings (p = .034). CONCLUSIONS In this limited sample, preliminary findings are consistent with similar intraoperative glycemic control between CSII continuation and CSII conversion to intravenous insulin infusions. Continuous subcutaneous insulin infusion suspension had a greater rate of hyperglycemia. Preoperative differences between insulin delivery groups complicate interpretations of findings.

Abstract
OBJECTIVE The Zwolle Outpatient Diabetes project Integrating Available Care (ZODIAC) study was initiated in 1998 to investigate the effects of shared care for patients with type 2 diabetes mellitus (T2DM) in the Netherlands, and to reduce the number of diabetes-related complications. Benchmarking the performance of diabetes care was and is an important aspect of this study. We aimed to investigate trends in diabetes care, within the ZODIAC study for a wide variety of quality indicators during a long follow-up period (1998-2008), with special interest for different age groups. DESIGN Prospective observational cohort study. SETTING Primary care, Zwolle, The Netherlands. PARTICIPANTS Patients with T2DM. METHODS A dataset of quality measures was collected annually during the patient's visit to the practice nurse or general practitioner. Linear time trends from 1998 to 2008 were estimated using linear mixed models in which we adjusted for age and gender. Age was included in the model as a categorical variable: for each follow-up year all participants were categorised into the categories <60, 60-75 and >75 years. Differences in trends between the age categories were investigated by adding an interaction term to the model. RESULTS The number of patients who were reported to participate increased in the period 1998-2008 from 1622 to 27 438. All quality indicators improved in this study, except for body mass index. The prevalence albuminuria decreased in an 11-year-period from 42% to 21%. No relevant differences between the trends for the three age categories were observed. During all years of follow-up, mean blood pressure and body mass index were the lowest and highest, respectively, in the group of patients <60 years (data not shown). CONCLUSIONS Quality of diabetes care within the Dutch ZODIAC study, a shared care project, has considerably improved in the period 1998-2008. There were no relevant differences between trends across various age categories.
