The relationship of glycosylated hemoglobin A1c and Apolipoprotein A‑1 ratio on short-term prognosis in STEMI patients following PCI: a retrospective study. Sci Rep 2025; 15:14110. [PMID: 40269200 PMCID: PMC12018918 DOI: 10.1038/s41598-025-99003-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2024] [Accepted: 04/16/2025] [Indexed: 04/25/2025] Open
Abstract
The ST segment elevation myocardial infarction (STEMI) patients tend to experience cardiovascular events following percutaneous coronary intervention (PCI), and the prognosis remains suboptimal. The objective of this investigation was to examine the correlation between the ratio of glycosylated hemoglobin A1c/Apolipoprotein A1 (HbA1c/ApoA-1) and the short-term prognosis in STEMI patients following PCI. This study conducted a retrospective analysis of the clinical data of 182 patients diagnosed with STEMI following PCI and admitted to our hospital between January 2022 and June 2023. The patients were categorized into two groups based on the occurrence of major adverse cardiovascular events (MACEs), and a comparative analysis of baseline characteristics was performed. The significant correlation between HbA1c/ApoA-1 with short-term MACEs in STEMI patients post-PCI were determined through univariate and multivariate logistic regression analysis. Different models and Subgroup analysis demonstrated that HbA1c/ApoA-1 was independent risk factor for MACEs in STEMI patients post-PCI and exhibited high stability. Receiver operating characteristic (ROC) curve and area under curve (AUC) value were utilized to validate the predictive value of HbA1c/ApoA-1 in forecasting outcomes among STEMI patients post-PCI, with an AUC of 0.752 (95% CI: 0.68-0.86), sensitivity of 85.7%, and specificity of 56.8%. Restricted cubic spline (RCS) was employed to evaluate the potential non-linear relationship between HbA1c/ApoA-1 levels and MACEs in STEMI patients post-PCI. Our results demonstrated high and significant correlation between HbA1c/ApoA-1 and short-term prognosis, and indicated that HbA1c/ApoA-1 was independent risk factor for MACEs in STEMI patients following PCI and possessed significant predictive value, facilitating the early identification of high-risk cohorts and the anticipation of MACEs.

Abstract
BACKGROUND Previous studies have reported that abnormal glucose metabolism is associated with poor cancer outcomes. Glycated hemoglobin A1c (HbA1c) is an important indicator of glucose metabolism. This study aimed to investigate the relationship between nondiabetic HbA1c levels and cancer-related mortality. METHODS This was a retrospective cohort study of Koreans who attended an annual or biennial health checkup program. The study group was categorized based on the quintile of HbA1c level (Q1, 3.0-5.1%; Q2, 5.2-5.3%; Q3, 5.4%; Q4, 5.5-5.6%, Q5, 5.7-6.4%). Cancer-related mortality was determined using the mortality data from the Korea National Statistical Office. Participants with an established diagnosis of diabetes or cancer were excluded. Cancer-related mortality was assessed depending on each HbA1c level with adjustment for factors that could influence mortality. RESULTS A total of 589,457 participants were included in this study. During a median follow-up duration of 6.99 years, 1712 cancer-related deaths were reported. The risk of cancer-related mortality was significantly higher in the Q5 group (hazard ratio (HR) 1.23, range 1.02-1.47 in model 1; HR 1.25, range 1.04-1.50 in model 2). HbA1c levels were linearly associated with cancer-related deaths (Ptrend = 0.021 in model 1; 0.013 in model 2). HbA1c level and colorectal, stomach, and lung cancer mortality exhibited a positive relationship, whereas liver cancer-related mortality showed an inverse relationship with HbA1c level (Ptrend = 0.001). CONCLUSIONS Our study showed that abnormal glucose metabolism is significantly associated with cancer-related mortality, and its relationship varies with each type of cancer.

Effects of aerobic and resistance exercise on glycosylated hemoglobin (HbA1c) concentrations in non-diabetic Taiwanese individuals based on the waist-hip ratio. PLoS One 2022; 17:e0267387. [PMID: 35511934 PMCID: PMC9071154 DOI: 10.1371/journal.pone.0267387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 04/07/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Glycosylated hemoglobin (HbA1c) reflects the average blood sugar over the past eight to twelve weeks. Several demographic and lifestyle factors are known to affect HbA1c levels. We evaluated the association of HbA1c with aerobic and resistance exercise in non-diabetic Taiwanese adults based on the waist-hip ratio (WHR). METHODS We conducted this study based on TWB data collected from 90,958 individuals between 2008 and 2019. We estimated the Beta (β) coefficient and 95% confidence intervals (CI) for HbA1c using multivariate regression models. RESULTS Based on the multivariate analysis, lower HbA1c levels were associated with both resistance exercise (β-coefficient = -0.027, 95% CI -0.037 to -0.017) and aerobic exercise (β-coefficient = 0.018, 95% CI, -0.023 to -0.013). Higher HbA1c levels were associated with abnormal WHR compared to normal WHR (β-coefficient = 0.091, 95% CI, 0.086 to 0.096). We detected an interaction between exercise and WHR (p for interaction = 0.0181). To determine the magnitude of the interaction, we performed additional analyses (with the reference group being 'abnormal WHR with no exercise') and observed substantial decreases in HbA1c regardless of the WHR and exercise category. However, the largest reduction occurred in the 'normal WHR and resistance exercise' group (β = -0.121, 95% CI, -0.132 to -0.109). CONCLUSIONS We found that normal resistance exercise, coupled with a normal WHR was significantly associated with lower HbA1c levels among non-diabetic individuals in Taiwan.

Abstract
PURPOSE OF REVIEW Prediabetes, or dysglycemia in the absence of diabetes, is a prevalent condition typically defined by a glycated hemoglobin (HgbA1c) of 5.7- < 6.5%. This article reviews current contemporary data examining the association between prediabetes and cardiovascular disease (CVD) as well as HgbA1c as a continuous measure of cardiovascular risk across the glycemic spectrum. RECENT FINDINGS Dysglycemia in the prediabetic range is associated with an increased risk of both subclinical and clinical CVD, including atherosclerotic CVD, chronic kidney disease, and heart failure. Several recent large, prospective studies demonstrate roughly linear risk with increasing HgbA1c, even below the threshold for prediabetes. "High-risk" patients with prediabetes have similar CVD risk as those with diabetes. HgbA1c below the threshold for diabetes stratifies CVD risk. Use of HgbA1c as a continuous measure, rather than simply dichotomized, may inform current and future prevention strategies. Given the high population attributable risk associated with prediabetes, targeted prevention strategies in this population warrant dedicated study.

Abstract
UNLABELLED Despite the improvement of treatment methods, survival of patients with glioblastoma is still low. Glioblastoma is the most common brain tumor. OBJECTIVE To study carbohydrate metabolism in patients with glioblastoma during adjuvant external beam radiation therapy and its impact on survival. MATERIAL AND METHODS The study included 66 patients with glioblastoma (Karnofsky score ≥80%) who underwent hypofractionated adjuvant external beam radiation therapy (single focal dose 2.5-3Gr). Patients received dexamethasone 4-8 mg daily throughout the entire course of irradiation. RESULTS High level of glycated hemoglobin (HbA1c) was observed in 33.3% of patients with glioblastoma undergoing irradiation. Cumulative survival was 17 months (95% CI 13.7-20.3). Two indicators had a significant negative impact on cumulative survival: age of patients (HR 1.04; 95% CI 1.01-1.08; p=0.02) and level of HbA1c (HR 1.94; 95% CI 1.23-3.06; p=0.005). Cumulative survival was significantly (p=0.022) higher in patients younger 53 years compared to older people (18 months and 14 months, respectively). Cumulative survival was 20 months among patients whose HbA1c did not exceed the upper reference value (<5.8%). Survival was higher (p=0.017) in these ones compared to patients with HbA1c ≥5.8% (13 months). According to multivariate Cox regression model, high HbA1c was the only significant negative predictor of cumulative survival (HR 3.35; 95% CI 1.14-9.81; p=0.027). CONCLUSION High HbA1c is unfavorable predictor of cumulative survival in patients with glioblastoma and Karnofski score ≥80% undergoing adjuvant hypofractionated irradiation regardless their age.

Abstract
OBJECTIVES To estimate the prevalence of prediabetes in individuals with moderate or severe periodontitis and to verify the association between periodontitis and glycated hemoglobin levels. MATERIAL AND METHODS A cross-sectional study was conducted including individuals age 18-93 years from a representative sample residing in rural Southern Brazil. Data collection included full mouth periodontal clinical examinations, laboratory screens, and structured questionnaires. Glycemic levels were based on glycated hemoglobin. Periodontitis case definition was based on criteria established by the Centers for Disease Control and Prevention and the American Academy of Periodontology. A logistic regression model adjusted for body mass index was used to estimate odds ratios (OR) and 95% confidence intervals (CI). The association between periodontal parameters and changes in glycated hemoglobin levels was evaluated using linear regression models. RESULTS A higher prevalence of prediabetes was observed among individuals with moderate (39.6%) and severe periodontitis (49.7%) than in individuals with mild (23.8%) or no periodontitis (27.8%). Adjusting for body mass index, individuals with severe periodontitis exhibited a 2.5 greater chance of being prediabetic (OR=2.5; 95% CI: 1.3-4.9) that was significantly associated with an increase of 0.10% in HbA1c. CONCLUSION Severe periodontitis was associated with elevated blood glucose levels. Individuals with this condition having a higher percentage HbA1c are more likely to be prediabetic. CLINICAL RELEVANCE This study highlights the importance of the clinicians' awareness of the association between severe periodontitis and prediabetes allowing its early detection in the dental office.

Abstract
BACKGROUND Because limited data are available, the present study investigated 2-year major clinical outcomes after angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II type 1 receptor blockers (ARBs) therapy in patients with acute myocardial infarction (AMI) and prediabetes after successful implantation of newer-generation drug-eluting stents (DESs). METHODS Overall, 2932 patients with AMI and prediabetes were classified into two groups - the ACEIs group (n = 2059) and the ARBs group (n = 873). The primary endpoint was the occurrence of patient- -oriented composite outcome (POCO), defined as all-cause death, recurrent myocardial infarction (Re-MI), or any repeat revascularization. The secondary endpoint was definite or probable stent thrombosis (ST). RESULTS The cumulative incidences of POCO (adjusted hazard ratio [aHR]: 1.020; 95% confidence interval [CI]: 0.740-1.404; p = 0.906), all-cause death (aHR: 1.394; 95% CI: 0.803-2.419; p = 0.238), Re-MI (aHR: 1.210; 95% CI: 0.626-2.340; p = 0.570), any repeat revascularization (aHR: 1.150; 95% CI: 0.713-1.855; p = 0.568), and ST (aHR: 1.736; 95% CI: 0.445-6.766; p = 0.427) were similar between the groups. These results were confirmed after propensity score-adjusted analysis. CONCLUSIONS In this study, patients with AMI and prediabetes who received ACEIs or ARBs showed comparable clinical outcomes during the 2-year follow-up period.

Abstract
BACKGROUND AND AIMS Glucose and lipid metabolism are major prognostic indicators of coronary heart disease. The ratio of plasma glycosylated hemoglobin A1c (HbA1c) to apolipoprotein A-l (ApoA-l) is an indirect measure of insulin resistance. The study aimed to evaluate whether the HbA1c/ApoA-1 ratio can predict the prognosis in patients with the acute coronary syndrome (ACS). METHODS AND RESULTS A total of 476 ACS patients diagnosed by coronary angiography were enrolled in this longitudinal, observational, retrospective study. Plasma HbA1c, fasting blood glucose and lipid profile were measured. Patients were stratified according to the tertiles of HbA1c/ApoA-l levels. Cox proportional hazard model was used to examine the predictive value of HbA1c/ApoA-l for study endpoints. The association between the Log HbA1c/ApoA-l ratio and major adverse cardiovascular events (MACEs) was estimated using multiple logistic regression. Baseline characteristics showed a mean age of 66 ± 8 years, and 52.5% were hypertensive, 26.8% diabetic, and 54.5% current or prior smokers. During a mean follow-up period of 22.3 ± 1.7 months, 59 deaths occurred. After adjusting for age, gender, smoking, hypertension, diabetes, and coronary artery disease severity, patients in the highest HbA1c/ApoA-l ratio tertile had a 4.36-fold increased risk of mortality compared with those in the lowest tertile. The multivariate logistic regression showed that the Log HbA1c/ApoA-l ratio was associated with MACEs (Odds ratio 2.95, p = 0.013). CONCLUSION After adjusting for traditional cardiovascular risk factors and ACS severity scores, the HbA1c/ApoA-1 ratio remained an independent predictor of all-cause mortality and MACEs in the ACS patients undergoing angiography.

Abstract
OBJECTIVES This study aimed to investigate the association between preoperative glycated hemoglobin (HbA1c) levels and the treatment outcomes of oral cavity squamous cell carcinoma (OSCC). METHODS Three hundred and fifty-eight OSCC patients were consecutively enrolled between July 2004 and July 2016. Clinicopathological parameters and survival outcomes were analyzed following HbA1c stratification of 6.5% (HbA1c ≥ 6.5%: n = 74, 20.6%) and 7.0% (HbA1c ≥ 7.0%: n = 53, 14.8%). RESULTS Higher HbA1c levels were associated with elevated body mass index, lower albumin levels, wider surgical margins, and prolonged hospital stays (HbA1c 6.5%: p = .001, .048, .030, .009, respectively; HbA1c 7.0%: p = .092, .032, .009, .015, respectively). Survival rates stratified by HbA1c 6.5% were as follows: locoregional recurrence-free survival, p = .014; distant metastasis-free survival, p = .013; second primary cancer-free survival, p = .015; overall survival, p = .014; disease-specific survival, p = .002 and HbA1c 7.0%: locoregional recurrence-free survival, p = .013; distant metastasis-free survival, p = .013; second primary cancer-free survival, p = .014; overall survival, p = .015; disease-specific survival, p = .004. Multivariate analyses identified HbA1c as an independent prognostic factor for overall and disease-specific survival (HbA1c 6.5%: p = .014 and .002, respectively; HbA1c 7.0%: p = .036 and .013, respectively). CONCLUSIONS Oral squamous cell carcinoma patients with higher preoperative HbA1c levels had longer hospitalization and worse survival outcomes.

Abstract
Background To determine whether the pro-inflammatory cytokine interleukin (IL)-1beta, as a marker of the nucleotide binding and oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation, can be used to predict cardiovascular disease (CVD) risk in patients with newly diagnosed, drug-naïve type 2 diabetes mellitus (T2DM). Methods A total of 110 subjects with no history of diabetes were enrolled and divided into control subjects (non-DM group, n=52) and patients with newly diagnosed, drug-naïve T2DM (DM group, n=58). Results Serum IL-1beta levels were not different between the two groups. The Framingham CVD risk score (F-score) was positively correlated with the serum IL-1beta level in the DM group. Multivariate regression analyses showed that the F-score was independently associated with the serum IL-1beta level in the DM group. Patients with an intermediate to high CVD risk (F-score ≥10%) also had significantly higher serum IL-1beta levels than did those with a low CVD risk (F-score <5%). Smokers in the DM group had higher IL-1beta levels than did those in the non-DM group, regardless of the F-score. Conclusions These results suggest that serum IL-1beta levels might be useful as an independent risk factor predicting CVD risk in patients with newly diagnosed, drug naïve T2DM, particularly those who smoke.

AUST HEALTH REV 2019; 43:85-91. [PMID: 28923165 DOI: 10.1071/ah16298] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2016] [Accepted: 08/14/2017] [Indexed: 11/23/2022]
Abstract
Objectives The aim of the present study was to determine the association between area-level socioeconomic disadvantage and glycaemic-related risk in health service users in the Illawarra-Shoalhaven region of New South Wales, Australia. Methods HbA1c values recorded between 2010 and 2012 for non-pregnant individuals aged ≥18 years were extracted from the Southern.IML Research (SIMLR) database. Individuals were assigned quintiles of the Socioeconomic Indices for Australia (SEIFA) Index of Relative Socioeconomic Disadvantage (IRSD) according to their Statistical Area 1 of residence. Glycaemic risk categories were defined as HbA1c 5.0-5.99% (lowest risk), 6.0-7.49% (intermediate risk) and ≥7.5% (highest risk). Logistic regression models were fit with glycaemic risk category as the outcome variable and IRSD as the study variable, adjusting for age and sex. Results Data from 29064 individuals were analysed. Higher disadvantage was associated with belonging to a higher glycaemic risk category in the fully adjusted model (most disadvantaged vs least disadvantaged quintile; odds ratio 1.74, 95% confidence interval 1.58, 1.93; P<0.001). Conclusion In this geocoded clinical dataset, area-level socioeconomic disadvantage was a significant correlate of increased glycaemic-related risk. Geocoded clinical data can inform more targeted use of health service resources, with the potential for improved health care equity and cost-effectiveness. What is known about the topic? The rapid increase in the prevalence of Type 2 diabetes (T2D), both globally and nationally within Australia, is a major concern for the community and public health agencies. Individual socioeconomic disadvantage is a known risk factor for abnormal glucose metabolism (AGM), including T2D. Although small-area-level socioeconomic disadvantage is a known correlate of AGM in Australia, less is known of the association of area-level disadvantage and glycaemic-related risk in individuals with AGM. What does this paper add? This study demonstrates a robust association between small-area-level socioeconomic disadvantage and glycaemic-related risk in regional New South Wales. The study demonstrates that it is feasible to use geocoded, routinely collected clinical data to identify communities at increased health risk. What are the implications for practitioners? The identification of at-risk populations is an essential step towards targeted public health policy and programs aimed at reducing the burden of AGM, its complications and the associated economic costs. Collaboration between primary care and public health in the collection and use of data described in the present study has the potential to enhance the effectiveness of both sectors.

Abstract
BACKGROUND Studies have confirmed that the low Ankle Brachial Index (ABI) and high glycated hemoglobin (HbA1c) level were both risk factors of cardiovascular disease (CVD). However, the association has rarely been explored between ABI and HbA1c. This study was to evaluate the independent relationship between HbA1c and low ABI. METHODS A total of 3102 subjects (male 1539, female 1563, aged 67.72±10.69 years) were enrolled into the study from 2010 to 2018. The odds ratio (OR) and linear regression coefficient of low ABI group (defined as ABI≤0.9) and ABI value in associations with the HbA1c were modelled using multivariable logistic and linear regression analyses by adjusting for possible confounders. RESULTS Compared with participants with normal ABI, those presenting the low ABI showed a significantly older age, smoking rate, higher level of heart rate (HR), systolic blood pressure (SBP), pulse pressure (PP), fasting plasma glucose (FPG), triglyceride (TG), highly sensitive C-reactive protein (hs-CRP), HbA1c and carotid femoral pulse wave velocity (CF-PWV); and higher prevalence rate of hypertension, diabetes, coronary artery disease (CAD); and higher rate on medication of statins, diabetes drug and cardiovascular drug (all P<0.001). After multiple adjustment for age, sex, smoke, FPG, blood lipids, hs-CRP, SBP, diastolic blood pressure (DBP), PP, CF-PWV, hypertension, diabetes, CAD and medications, the OR of HbA1c for low ABI was of statistical significance (95% CI: 1.204-1.410, P<0.001). After further multivariate adjustment analysis by linear regression, with left and right ABI as dependent variables, the results showed that HbA1c was independently linearly correlated to left and right ABI (all P<0.001). CONCLUSIONS HbA1c was an independent associated factor of lower ABI and linearly correlated to ABI level independent of fasting plasma glucose and other cardiovascular factors. We should not only focus on the HbA1c in diabetes mellitus patients, but also people with lower ABI.

Abstract
INTRODUCTION Cinnamon has been used as a dietary component and in the management of diabetes mellitus. This study systematically reviewed and synthesized evidence on the efficacy of cinnamon for the treatment of type 2 diabetes mellitus (T2DM) and pre-diabetes patients. METHODS Databases of Web of Sciences, the Cochrane library, PubMed, CINAHL and SCOPUS were searched. Stata version 13 (College Station, Texas 77845 USA) and RevMan var. 5.3 software were used for meta-analysis. Heterogeneity was assessed using Chi-square and I2 tests. RESULTS Sixteen randomized controlled studies were included in the meta-analysis. Cinnamon significantly reduced fasting blood glucose (FBG) and homeostatic model assessment for insulin resistance (HOMA-IR) level compared to placebo with weighted mean difference (WMD) of -0.545 (95% CI: -0.910, -0.18) mmol/L, I2 = 83.6% and -0.714(-1.388, -0.04), I2 = 84.4% respectively. There was no significant change in weighted mean difference of glycosylated hemoglobin A1C (HbA1c) % and lipid profiles (mmol/L). Meta-regression did not show any factor significantly affecting the treatment response. CONCLUSION Cinnamon reduced FBG and HOMA-IR, level in T2DM and pre-diabetes patients compared to placebo. High heterogeneity observed among included studies warrants further clinical trials after standardization of cinnamon formulation.

Abstract
The association between hyperglycemia and prostate cancer risk is inconsistent, and its association with prostate cancer mortality is understudied. Thus, we investigated the association between hyperglycemia and prostate cancer risk and mortality using multiple biomarkers simultaneously to classify hyper- and normoglycemia. We conducted a prospective analysis of 5,162 cancer-free men attending visit 2 (1990-1992) of the Atherosclerosis Risk in Communities (ARIC) study followed for total (N = 671) and lethal (N = 69) prostate cancer incidence and prostate cancer mortality (N = 64) through 2012. Men without diagnosed diabetes were classified as normo- or hyperglycemic using joint categories of fasting glucose, glycated hemoglobin, and glycated albumin (or fructosamine) defined by clinical or research cutpoints. We evaluated the multivariable-adjusted association of hyperglycemia with prostate cancer incidence and mortality using Cox proportional hazards regression; men with diagnosed diabetes were included as a separate exposure category. Among 4,753 men without diagnosed diabetes, 61.5% were classified as having hyperglycemia (high on ≥1 biomarker). HbA1c and glycated albumin together classified 61.9% of 1,736 men with normal fasting glucose as normoglycemic. Compared with men who were normal on all three biomarkers, men who were high on ≥1 biomarker had an increased risk of lethal [HR, 2.50; 95% confidence interval (CI), 1.12-5.58] and fatal (HR, 3.20; 95% CI, 1.26-8.48) disease, but not total prostate cancer incidence (HR, 0.98; 95% CI, 0.81-1.20); associations were similar including fructosamine instead of glycated albumin. Our findings indicate hyperglycemia is associated with an increased risk of lethal and fatal prostate cancer, but not total prostate cancer incidence.

Abstract
OBJECTIVES To explore the clinical utility of glycated hemoglobin (A1C) levels as an early marker of albuminuria, macrovascular disease and subclinical cardiovascular disease in comparison to fasting and postprandial glucose levels in a well-characterized Chinese population with no history of diabetes. METHODS The study population consisted of 1223 individuals who were enrolled in the Guangzhou Biobank Cohort Study, Cardiovascular Disease Subcohort, and who had undergone oral glucose tolerance tests. The associations between each glycemic measure and albuminuria, carotid intima-media thickness (CIMT) and CIMT-based presence of carotid plaques and aortic arch calcification were assessed by chest radiographs. RESULTS The overall prevalence of albuminuria, carotid plaque and any aortic arch calcification was 20.6%, 22.8% and 25.8%, respectively. All 3 glycemia indices were significantly associated with albuminuria, but only 1 (fasting glucose) was associated with carotid plaques. No significant difference was detected among them in the area under the curve for albuminuria (chi-square test; p=0.84), carotid plaques (p=0.28) or calcifications (p=0.29). In sensitivity analysis, adjusted for age and sex, the above findings remained unchanged. CONCLUSIONS Although there was evidence suggesting differential associations, the performance of the glycemic indices was similar, and their association with macrovascular disease and albuminuria was modest.

Associations of mid-pregnancy HbA1c with gestational diabetes and risk of adverse pregnancy outcomes in high-risk Taiwanese women. PLoS One 2017; 12:e0177563.

Abstract
BACKGROUND The objective of this study was to investigate the associations among the mid-pregnancy glycated hemoglobin A1c (HbA1c) level, gestational diabetes (GDM), and risk of adverse pregnancy outcomes in women without overt diabetes and with positive 50-g, 1-h glucose challenge test (GCT) results (140 mg/dL or greater). METHODS This prospective study enrolled 1,989 pregnant Taiwanese women. A two-step approach, including a 50-g, 1-h GCT and 100-g, 3-h oral glucose tolerance test (OGTT), was employed for the diagnosis of GDM at weeks 23-32. The mid-pregnancy HbA1c level was measured at the time the OGTT was performed. A receiver operating characteristic (ROC) curve was used to determine the relationship between the mid-pregnancy HbA1c level and GDM. Multiple logistic regression models were implemented to assess the relationships between the mid-pregnancy HbA1c level and adverse pregnancy outcomes. RESULTS An ROC curve demonstrated that the optimal mid-pregnancy HbA1c cut-off point to predict GDM, as diagnosed by the Carpenter-Coustan criteria using a two-step approach, was 5.7%. The area under the ROC curve of the mid-pregnancy HbA1c level for GDM was 0.70. Compared with the levels of 4.5-4.9%, higher mid-pregnancy HbA1c levels (5.0-5.4, 5.5-5.9, 6.0-6.4, 6.5-6.9, and >7.0%) were significantly associated with increased risks of gestational hypertension or preeclampsia, preterm delivery, admission to the neonatal intensive care unit, low birth weight, and macrosomia (the odds ratio [OR] ranges were 1.20-9.98, 1.31-5.16, 0.88-3.15, 0.89-4.10, and 2.22-27.86, respectively). CONCLUSIONS The mid-pregnancy HbA1c level was associated with various adverse pregnancy outcomes in high-risk Taiwanese women. However, it lacked adequate sensitivity and specificity to replace the two-step approach in the diagnosis of GDM. The current study comprised a single-center prospective study; thus, additional, randomized control design studies are required.

Abstract
AIM To identify the relationship between HbA1c and cancers in people with or without diabetes. BACKGROUND Cancer is a major public health problem, accounting for 8.2 million deaths worldwide in 2012. HbA1c level has been associated with the risk of developing certain cancers, although the existing evidence is conflicting. METHODS EMBASE, MEDLINE, CINAHL and the Cochrane Library were searched. Eligible articles included randomized controlled trials, cohort studies, case-control studies, systematic reviews and meta-analyses. Participants of either sex, with or without Type 1 or 2 diabetes, were included. The studies were assessed using the Scottish Intercollegiate Guidelines Network (SIGN) criteria by two independent assessors. No meta-analysis was performed because of the heterogeneity of results. RESULTS A total of 19 studies from 1006 met the inclusion criteria, of which 14 were cohort studies and five were nested case-control studies. Eight studies investigated outcomes for all cancer sites. Four of these studies reported that higher HbA1c levels were associated with higher incidence and/or mortality risk for all cancers. One study observed a U-shaped relationship between HbA1c and cancer incidence and mortality. Increasing HbA1c levels were associated with increasing risk of developing colorectal, pancreatic, respiratory and female genital tract cancers. No increased risk was observed for breast cancer, gastrointestinal or urological malignancies. CONCLUSION HbA1c appears to be associated with cancer incidence and/or cancer mortality, but further studies are needed to fully understand the complex relationship between HbA1c and cancer.

Glycated hemoglobin and long-term prognosis in patients with suspected stable angina pectoris without diabetes mellitus: a prospective cohort study. Atherosclerosis 2015; 240:115-20. [PMID: 25770690 DOI: 10.1016/j.atherosclerosis.2015.02.053] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2014] [Revised: 01/23/2015] [Accepted: 02/23/2015] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Associations of glycated hemoglobin A1c (HbA1c) levels to incident coronary and cardiovascular events among non-diabetic patients with coronary artery disease are unclear. We investigated relations of HbA1c to long-term prognosis in such patients. METHODS A prospective cohort of 2519 patients undergoing elective coronary angiography for suspected stable angina pectoris (SAP) was divided into pre-defined categories according to HbA1c (%) levels (<5.0, 5.0-5.6 (reference), 5.7-6.4), and followed for median 4.9 years. The primary end-point was major coronary events (including non-fatal and fatal acute myocardial infarctions, and sudden cardiac death). Secondary end-points were death from cardiovascular disease (CVD) and all-cause mortality. Hazard ratios (HRs) (95% confidence intervals [CIs]) were obtained by Cox regression. RESULTS Median age at inclusion was 62 years, 73% were males, median HbA1c was 5.6% and random plasma-glucose 5.4 mmol/L. After multivariate adjustment, HbA1c levels within the pre-diabetic range were not associated with risk of major coronary events, HR (95% CI): 1.13 (0.79-1.62); P=0.49, death from CVD or all-cause mortality HR (95% CI): 0.95 (0.55-1.66) and 1.04 (0.70-1.53), respectively; P≥0.85. Similarly, there was no significant association between HbA1c values within the lowest category and risk of study outcomes, (P≥0.18). CONCLUSION In non-diabetic patients with suspected SAP, there was no overall association between HbA1c levels and prognosis, questioning an independent role of glycemia in the pathogenesis of atherosclerotic complications in these patients.

Abstract
Background To investigate relationship between glycated hemoglobin (HbA1c) level and coronary artery disease (CAD) severity. Methods Observational study was conducted and 573 participants were enrolled and baseline characteristics were collected. Clinical presentations in terms of stable angina, unstable angina or acute myocardial infarction were diagnosed. All participants were performed coronary angiography to figure out the numbers of coronary artery stenosis in terms of none-stenosis (< 50% stenosis), single or multiple vessels stenoses (≥ 50% stenosis). All participants were divided into subgroups according to two categories in terms of severity of clinical presentation (stable angina, unstable angina, or acute myocardial infarction) and the number of coronary artery stenosis (none, single, and multiple vessels). Primary endpoint was to evaluate relationship between baseline HbA1c value and CAD severity. Results Consistent to previous studies, participants with CAD had more risk factors such as elderly, smoking, low HDL-C and high CRP levels. Notably, HbA1c level was more prominent in CAD group than that without CAD. As compared to stable angina subgroup, HbA1c levels were gradually increased in unstable angina and acute myocardial infarction groups. Similar trend was identified in another category in terms of higher HbA1c level corresponding to more vessels stenoses. Multivariate regression analyses showed that after adjusted for traditional risk factors as well as fasting blood glucose, HbA1c remained strongly associated with the severity of CAD. Nonetheless, there was no significant association when CRP was accounted for. Conclusion HbA1c may be a useful indicator for CAD risk evaluation in non-diabetic adults.

Abstract
This study examined whether glycated hemoglobin A1C (HbA1C) and chronic liver diseases are associated with hepatocellular carcinoma (HCC) risk in Type 2 diabetic patients. A retrospective cohort study consisting of 51,705 patients with Type 2 diabetes aged 30 and over enrolled in the National Diabetes Care Management Program before 2004 was used in Cox proportional hazards models. HbA1C was independently associated with HCC incidence, and multivariate-adjusted hazard ratio (HR) of HCC was 1.20 (95% confidence interval, CI: 1.02-1.41) for patients with a level of HbA1c ≥ 9% compared with patients with a level of HbA1c <7% after multivariate adjustment. We observed a significant linear trend in HCC incidence with increasing HbA1c (p for trend = 0.02, HR = 1.07, 95% CI = 1.01-1.12 for every 1% increment in HbA1c). We observed significant HRs of HCC for patients with a level of HbA1c ≥ 9% with alcoholic liver damage, liver cirrhosis, HBV, HCV and any one of chronic liver diseases compared with patients with a level of HbA1c <9% and no counterpart comorbidity in the entire sample (HR = 8.63, 95% CI = 1.41-52.68; HR = 5.02, 95% CI = 3.10-8.12; HR = 2.53, 95% CI = 1.10-5.85; HR = 1.79, 95% CI = 1.01-3.17; and HR = 3.59, 95% CI = 2.56-5.02, respectively). Our results suggest significant joint associations of HbA1c ≥ 9% and chronic liver diseases. Lifestyle or treatment interventions such as maintaining a satisfactory glycemic control and chronic liver diseases may reduce the burden of HCC.

Abstract
BACKGROUND Elevated glycated hemoglobin (HbA1c) is associated with increased risk of cardiovascular disease (CVD) and mortality but little is known about potential mechanisms underlying the reported associations. METHODS We used data from 1798 non-diabetic participants from the population-based cohort Study of Health in Pomerania (SHIP) to investigate cross-sectional and longitudinal associations of HbA1c with subclinical atherosclerosis (common carotid artery intima-media thickness [CCA-IMT]), cardiac structure (left ventricular mass [LVM]), and cardiac function (fractional shortening). RESULTS Cross-sectional analyses revealed a positive association between HbA1c and mean CCA-IMT with a 0.02 mm (95% confidence interval: 0.01-0.04) increase in CCA-IMT per 1% increase in HbA1c, and a similar positive trend across HbA1c quartiles (overall p-value <0.01). We also observed a graded association between HbA1c and high CCA-IMT (>75th percentile) with an odds ratio of 1.42 (95% CI: 1.11-1.81) per 1% increase in HbA1c. Longitudinal analyses showed no consistent associations of baseline HbA1c with mean follow-up CCA-IMT. There were no consistent associations of HbA1c with cardiac remodeling in cross-sectional and longitudinal analyses, respectively. CONCLUSIONS The association between HbA1c and CCA-IMT in non-diabetic adults may be a crucial link between high-normal HbA1c levels and an increased risk of CVD and mortality.

Abstract
OBJECTIVE We investigated the cardiovascular risk profile in subjects with prediabetes and new-onset type 2 diabetes identified by glycated hemoglobin A1c (HbA(1c)) according to the new American Diabetes Association criteria. RESEARCH DESIGN AND METHODS Arterial stiffness, intima-media thickness (IMT), soluble receptor for advanced glycation end products (sRAGEs), and oral glucose tolerance test (OGTT) were evaluated in 274 subjects without a previous history of diabetes. The subjects were stratified into three groups according to the HbA(1c) levels. RESULTS The subjects with prediabetes (n = 117, HbA(1c) 5.7-6.4% [39-46 mmol/mol]) showed a higher augmentation (Aug), augmentation index (AugI), and IMT compared with those with lower HbA1c; however, these values were similar to those of subjects with HbA(1c) >6.5% (48 mmol/mol). When we further analyzed the subjects with prediabetes but included only subjects with normal glucose tolerance (NT) in the analysis, AugI and IMT still remained significantly higher than their levels in control subjects with HbA(1c) <5.7% (39 mmol/mol). After multiple regression analyses including several cardiovascular risk factors, only HbA(1c), age, and sRAGE were significantly correlated with the IMT, whereas age and 1-h postload glucose were the major determinants of AugI. CONCLUSIONS Our data show that subjects with prediabetes according to HbA1c, but with both NT according to the OGTT and normal fasting glycemia, have an altered IMT and AugI. These data suggest that a simple, reproducible, and less expensive marker such as HbA1c may be better able to identify prediabetic subjects at high cardiovascular risk compared with fasting glycemia or OGTT alone.

Abstract
Objectives Glycated hemoglobin (HbA1c) is associated with an increased risk of cardiovascular disease. The aim of this study was to examine the relationship between HbA1c levels and the complexity of coronary artery lesions among the older patients with diabetes mellitus (DM). Methods This retrospective study enrolled a total of 3805 consecutive type 2 DM patients aged 60 years and older who underwent their first elective coronary angiography and had their HbA1c levels measured at the Chinese PLA General Hospital between December 2005 and December 2012.The complexity of the coronary artery lesions was evaluated using the Syntax score, and the subjects were divided into three groups according to their HbA1c levels. Logistic regression and Pearson correlation were used to analyze the association between the measured HbA1c levels and Syntax score. Results The mean age was 72.3±10.6 years. The higher HbA1c levels were significantly associated with higher Syntax score (p<0.001). The unadjusted correlation coefficient of HbA1c levels and the Syntax score was 0. 371 (p<0.001). In addition, the higher HbA1c categories were able to independently predict patients with intermediate or high Syntax score (Syntax score ≥23) after adjustment for age, sex, hypertension, smoking, dyslipidemia and creatinine levels in the logistic regression analysis. Conclusion HbA1c is significantly associated with the complexity of coronary lesions among older patients with DM. A higher HbA1c value is an independent predictor of the prevalence of complex coronary lesions. Further prospective multi-centre studies are needed to confirm this finding.

Abstract
BACKGROUND Admission glucose levels have proven to be a predictor in patients with acute myocardial infarction and elevated glycosylated hemoglobin A1c (HbA1c) is associated with an increased risk of cardiovascular disease, even in patients without diabetes. However, the effect of both admission glucose and HbA1c levels on clinical outcomes in non-diabetic patients with acute coronary syndrome (ACS) has not been fully elucidated. We evaluated the combined effect of admission glucose and HbA1c values on long-term clinical outcomes in non-diabetic patients with ACS treated with percutaneous coronary intervention (PCI). METHODS AND RESULTS This was an observational study of 452 consecutive non-diabetic patients with ACS who underwent PCI between January 1997 and December 2006. The patients were assigned to four groups according to the median values of admission glucose and HbA1c. The primary endpoint comprising a composite of all-cause death and non-fatal MI was compared among the four groups. The primary endpoint occurred in 13.3% of the participants during a median follow-up period of 4.7 years. The cumulative incidence rate of primary endpoint significantly differed among the groups (p=0.048). Multivariable Cox regression analysis showed that the combination of elevated admission glucose and HbA1c was independently associated with long-term clinical outcomes. CONCLUSIONS Combined admission glucose and HbA1c values were independently associated with clinical outcomes in non-diabetic patients with ACS treated with PCI.

Abstract
OBJECTIVE To explore the relationship between glycated haemoglobin A1C (HbA1C) and subclinical atherosclerosis as assessed by carotid intima-media thickness (cIMT) in Chinese Han obese children and adolescents without diabetes. METHODS A total of 524 obese children and adolescents without diabetes were analysed. All participants underwent HbA1C measurements, oral glucose tolerance tests and ultrasound measurements of cIMT. The logistic regression models were implemented to evaluate the adjusted OR of HbA1C for increased cIMT. RESULTS In obese boys, HbA1C was associated with increased cIMT independently of age, measurements of anthropometry, blood pressure, plasma lipid and lipoprotein, fasting plasma glucose, 2 h postchallenge glucose, uric acid and hepatic function. After adjustment for all these risk factors, the OR of increased cIMT for every 1% (11 mmol/mol) increase in HbA1C was 2.702 (95% CI 1.640 to 4.452). However, in girls, the major risk factor independently associated with cIMT was measurement of abdominal obesity instead of HbA1C. CONCLUSIONS Our research suggests that the adoption of HbA1C as a diagnostic criterion of prediabetes and diabetes in obese boys may help to identify early macrovascular complications.

Abstract
A change in the American Diabetes Association guidelines added hemoglobin A1c (HbA1c) to the assays for diabetes diagnosis, but evidence suggests that glucose vs. HbA1c criteria may identify different segments of the affected population. We previously demonstrated that oral findings offer an opportunity for the detection of undiagnosed abnormal fasting plasma glucose (FPG) among dental patients who present with diabetes risk factors. In this new cross-sectional study, we sought to extend these observations. The first goal, using data from 591 new participants, was to assess our previously identified hyperglycemia detection models when HbA1c is used for case definition. The second goal, using data from our total cohort of 1,097 participants, was to evaluate the models’ performance regardless of whether an FPG or an HbA1c is used for diagnosis. The presence of ≥ 26% teeth with deep pockets or ≥ 4 missing teeth correctly identified 72% of pre-diabetes or diabetes cases in the HbA1c sample and 75% in the total population. The addition of a point-of-care HbA1c ≥ 5.7% increased correct identification to 87% and 90%, respectively. These results demonstrate the validity of our prediction models regardless of the test used for diabetes or pre-diabetes diagnosis in the clinical setting and underscore the contribution dentists can make.

Abstract
BACKGROUND Connecting peptide (C-peptide) plays a role in early atherogenesis in patients with diabetes mellitus and may be a marker for cardiovascular morbidity and mortality in patients without diabetes. We investigated whether serum C-peptide levels are associated with all-cause, cardiovascular-related and coronary artery disease-related mortality in adults without diabetes. METHODS We used data from the Third Nutrition and Health Examination Survey (NHANES III) and the NHANES III Linked Mortality File in the United States. We analyzed mortality data for 5902 participants aged 40 years and older with no history of diabetes and who had available serum C-peptide levels from the baseline examination. We grouped the participants by C-peptide quartile, and we performed Cox proportional hazards regression analysis. The primary outcome was all-cause, cardiovascular-related and coronary artery disease-related mortality. RESULTS The mean serum C-peptide level in the study sample was 0.78 (± standard deviation 0.47) nmol/L. The adjusted hazards ratio comparing the highest quartile with the lowest quartile was 1.80 (95% confidence interval [CI] 1.33-2.43) for all-cause mortality, 3.20 (95% CI 2.07-4.93) for cardiovascular-related mortality, and 2.73 (95% CI 1.55-4.82) for coronary artery disease-related mortality. Higher C-peptide levels were associated with increased mortality among strata of glycated hemoglobin and fasting serum glucose. INTERPRETATION We found an association between serum C-peptide levels and all-cause and cause-specific mortality among adults without diabetes at baseline. Our finding suggests that elevated C-peptide levels may be a predictor of death.

Abstract
BACKGROUND Several studies have suggested that elevated levels of hemoglobin A1c (HbA1c) are associated with cardiovascular disease (CVD) in nondiabetic individuals. However, it is unclear whether HbA1c levels can serve as a simple screening marker for increased CVD risk in nondiabetic individuals. Our objective was to evaluate the relationship between HbA1c levels and CVD risk using the Framingham risk score (FRS) in older, apparently healthy nondiabetic Korean adults. METHODS We retrospectively studied 2,879 Korean adults between the ages of 40 and 79 who underwent voluntary health check-ups at the Health Promotion Center of our hospital from July 2009 to June 2011. Subjects were subdivided based on their HbA1c levels into four groups: tertiles within the HbA1c normal tolerance range and a group for subjects with an increased risk for diabetes (IRD). RESULTS The mean FRS for the upper tertile (9.6±3.8) group was significantly higher than that of the middle tertile (8.4±4.0) and lower tertile (7.6±3.8) groups. In addition, FRS was highest in the IRD group (10.5±3.7). Multiple linear regression analysis demonstrated that HbA1c levels exhibited a significant positive correlation with FRS when adjusted for confounding variables in all subjects (β±standard error [SE], 0.018±0.002; R (2), 0.131), women (β±SE, 0.023±0.003; R (2), 0.170), and men (β±SE, 0.016±0.004; R (2), 0.109). CONCLUSION HbA1c levels were positively correlated with FRS in older, apparently healthy nondiabetic Korean adults. We propose that HbA1c levels may reflect CVD risk in nondiabetic individuals.

Abstract
OBJECTIVE C-peptide is a proinsulin cleavage product released from the pancreas in amounts equimolar to insulin, and elevated levels of C-peptide have been found in patients with insulin resistance and early type 2 diabetes mellitus. Recent data suggest that C-peptide could play a causal role in the pathophysiology of vascular disease, but nothing is known about the prognostic value of C-peptide concentrations in the circulation. RESEARCH DESIGN AND METHODS We examined whether C-peptide is associated with cardiovascular and total mortality in 2,306 patients from the Ludwigshafen Risk and Cardiovascular Health Study who underwent coronary angiography at baseline (1997-2000). RESULTS During a mean follow-up of 7.6 years, 440 deaths (19.1%) occurred, 252 (10.9%) of which were due to cardiovascular causes. Age- and sex-adjusted hazard ratios (HRs) in the third compared with the first tertile of C-peptide were 1.46 (95% CI 1.15-1.85; P = 0.002) for all cause and 1.58 (1.15-2.18; P = 0.005) for cardiovascular mortality. After further adjustment for common risk factors as well as markers of glucose metabolism, these HRs remained significant at 1.46 (1.10-1.93; P = 0.008) and 1.55 (1.07-2.24; P = 0.022), respectively. Moreover, patients in higher tertiles of C-peptide exhibited higher levels of markers of endothelial dysfunction and atherosclerosis as well as a more severe extent of coronary lesions. CONCLUSIONS In patients undergoing coronary angiography, C-peptide levels are independently associated with all cause and cardiovascular mortality as well as presence and severity of coronary artery disease. Further studies are needed to examine a potential causal role of C-peptide in atherogenesis in humans.

Abstract
BACKGROUND Impaired glucose metabolism has been linked with increased cancer risk, but the association between serum glucose and cancer risk remains unclear. We used repeated measurements of glucose and fructosamine to get more insight into the association between the glucose metabolism and risk of cancer. METHODS We selected 11,998 persons (>20 years old) with four prospectively collected serum glucose and fructosamine measurements from the Apolipoprotein Mortality Risk (AMORIS) study. Multivariate Cox proportional hazards regression was used to assess standardized log of overall mean glucose and fructosamine in relation to cancer risk. Similar analyses were performed for tertiles of glucose and fructosamine and for different types of cancer. RESULTS A positive trend was observed between standardized log overall mean glucose and overall cancer risk (HR= 1.08; 95% CI: 1.02-1.14). Including standardized log fructosamine in the model resulted in a stronger association between glucose and cancer risk and aninverse association between fructosamine and cancer risk (HR = 1.17; 95% CI: 1.08-1.26 and HR: 0.89; 95% CI: 0.82-0.96, respectively). Cancer risks were highest among those in the highest tertile of glucose and lowest tertile of fructosamine. Similar findings were observed for prostate, lung, and colorectal cancer while none observed for breast cancer. CONCLUSION The contrasting effect between glucose, fructosamine, and cancer risk suggests the existence of distinct groups among those with impaired glucose metabolism, resulting in different cancer risks based on individual metabolic profiles. Further studies are needed to clarify whether glucose is a proxy of other lifestyle-related or metabolic factors.

Abstract
OBJECTIVE Although metabolic syndrome (MS) is considered to be a predictor of diabetes and cardiovascular disease, its value for predicting diabetes beyond the levels of fasting glucose (FG) and hemoglobin A1c (HbA1c) remains questionable. In this study, we evaluated the usefulness of MS and Japanese MS (JMS) as predictors of diabetes. METHODS This study is a longitudinal study using data for 2,034 subjects who visited our Medical Check-up Center in both 2008 and 2011 and were free from diabetes at baseline. The odds ratios (ORs) of developing diabetes in 2011 for MS and JMS were calculated after being adjusted for FG, age, sex and antihypertensive and antihyperlipidemic medication use, then further adjusted for HbA1c. The optimal cutoff points for FG, HbA1c and body mass index (BMI) to discriminate the development of diabetes and their sensitivities/specificities were obtained from receiver operating characteristic curves. These sensitivities/specificities were compared with the sensitivities/specificities of MS and JMS. RESULTS The ORs (95% confidence intervals (CIs)) of developing diabetes for MS and JMS were 1.36 (0.57-3.23) (p=0.484) and 3.23 (1.25-8.36) (p=0.016), respectively, after being adjusted for FG and 1.06 (0.39-2.86) (p=0.915) and 2.34 (0.79-6.95) (p=0.126), respectively, after being further adjusted for HbA1c. The sensitivities/specificities of FG, HbA1c, BMI, MS and JMS were 0.625/0.897, 0.828/0/919, 0.625/0.734, 0.375/0.911, and 0.375/0.941, respectively. CONCLUSION MS and JMS were found to be poor predictors of diabetes in a Japanese health screening population.

Abstract
BACKGROUND Reports on the determinants of morbidity in coronary artery bypass graft surgery (CABG) have focused on outcome measures such as length of postoperative stay in the Intensive Care Unit (ICU). We proposed that major comorbidities in the ICU hampered the prognostic effect of other weaker but important preventable risk factors with effect on patients' length of hospitalization. So we aimed at evaluating postoperative length of stay in the ICU and surgical ward separately. METHODS We studied isolated CABG candidates who were not dialysis dependent. Preoperative, operative, and postoperative variables as well as all classic risk factors of coronary artery disease were recorded. Using multivariate analysis, we determined the independent predictors of length of stay in the ICU and in the surgical ward. RESULTS Independent predictors of extended length of stay in the surgical ward ( > 3 days) were a history of peripheral vascular disease, total administered insulin during a 24-hour period after surgery, glycosylated hemoglobin (HbA1c), last fasting blood sugar of the patients before surgery, and inotropic usage after cardiopulmonary bypass. The area under the Receiver Operating Characteristic Curve (AUC) was found to be 0.71 and Hosmer-Lemeshow (HL) goodness of fit statistic p value was 0.88. Independent predictors of extended length of stay in the ICU ( > 48 hours) were surgeon category, New York Heart Association functional class, intra-aortic balloon pump, postoperative arrhythmias, total administered insulin during a 24-hour period after surgery, and mean base excess of the first 6 postoperative hours (AUC = 0.70, HL p value = 0.94). CONCLUSION This study revealed that the indices of glycemic control were the most important predictors of length of stay in the ward after cardiac surgery in all patients, diabetic or non-diabetic. However, because HbA1c level did not change under the influence of perioperative events, it could be deemed a valuable measure in predicting outcome in CABG candidates.

Abstract
AIMS The GERODIAB study is the first French multicentre, prospective, observational study that aims, through a 5-year cohort follow-up, to evaluate the link between glycaemic control and morbidity/mortality of type 2 diabetic (T2D) patients aged 70 years and older. This first report describes the study population at inclusion. PATIENTS AND METHODS A total of 987 T2D autonomous patients, aged ≥70 years, were recruited between June 2009 and July 2010 at 56 investigator centres. Their general parameters, diabetes characteristics and standard geriatric parameters were recorded. RESULTS The patients' mean age was 77±5 years, with 65.2% aged 75 years or more. The mean BMI was close to 30 kg/m(2). Hypertension was found in 89.7% of patients, and 85.0% had at least one cholesterol abnormality. The mean duration of the diabetes was around 18 years, and the mean HbA(1c) level was about 7.5%. During the previous six months, 33.6% of patients had experienced one or several hypoglycaemias. Also, 26% of patients presented with diabetic retinopathy, 37.3% had a GFR<60 mL/min, 31.2% had coronary insufficiency, 10.1% had heart failure, 15.8% had cerebrovascular involvement and 25.6% had peripheral vascular disease of the lower extremities. In addition, 30.5% of patients had orthostatic hypotension, 12.4% had malnutrition and 28.8% had cognitive impairment, all of which were often diagnosed at inclusion. Three-quarters of patients were taking an oral antidiabetic drug and nearly six in every 10 patients were using insulin. CONCLUSION This population can be considered representative of elderly, autonomous T2D patients, and its follow-up should clarify the link between glycaemic control and mortality/morbidity.

Impact of current treatments on liver disease, glucose metabolism and cardiovascular risk in non-alcoholic fatty liver disease (NAFLD): a systematic review and meta-analysis of randomised trials. Diabetologia 2012; 55:885-904.

Abstract
AIMS/HYPOTHESIS Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum ranging from simple steatosis to non-alcoholic steatohepatitis (NASH): NAFLD causes an increased risk of cardiovascular disease, diabetes and liver-related complications (the latter confined to NASH). The effect of proposed treatments on liver disease, glucose metabolism and cardiovascular risk in NAFLD is unknown. We reviewed the evidence for the management of liver disease and cardio-metabolic risk in NAFLD. METHODS Publications through November 2011 were systematically reviewed by two authors. Outcomes evaluated though standard methods were: histological/radiological/biochemical features of NAFLD, variables of glucose metabolism and cardiovascular risk factors. Seventy-eight randomised trials were included (38 in NASH, 40 in NAFLD): 41% assessed post-treatment histology, 71% assessed glucose metabolism and 88% assessed cardiovascular risk factors. Lifestyle intervention, thiazolidinediones, metformin and antioxidants were most extensively evaluated. RESULTS Lifestyle-induced weight loss was safe and improved cardio-metabolic risk profile; a weight loss ≥7% improved histological disease activity, but was achieved by <50% patients. Statins and polyunsaturated fatty acids improved steatosis, but their effects on liver histology are unknown. Thiazolidinediones improved histological disease activity, glucose, lipid and inflammatory variables and delayed fibrosis progression. Pioglitazone also improved blood pressure. Weight gain (up to 4.8%) was common. Antioxidants yielded mixed histological results: vitamin E improved histological disease activity when administered for 2 years, but increased insulin resistance and plasma triacylglycerols. CONCLUSIONS/INTERPRETATION Weight loss is safe, and improves liver histology and cardio-metabolic profile. For patients not responding to lifestyle intervention, pioglitazone improves histological disease activity, slows fibrosis progression and extensively ameliorates cardio-metabolic endpoints. Further randomised controlled trials (RCTs) of adequate size and duration will assess long-term safety and efficacy of proposed treatments on clinical outcomes.

Abstract
Diabetes is a risk factor for many cancers; chronic hyperglycemia is hypothesized to be, in part, explanatory. We evaluated the association between glycated hemoglobin, a time-integrated glycemia measure, and cancer incidence and mortality in nondiabetic and diabetic men and women. We conducted a prospective study of 12,792 cancer-free participants attending the second visit (1990-1992) of the Atherosclerosis Risk in Communities (ARIC) Study. We measured glycated hemoglobin in whole-blood samples using HPLC. Incident cancers were ascertained from registries and hospital records through 2006. We estimated multivariable-adjusted hazard ratios (HR) of cancer incidence and mortality for nondiabetic participants with values ≥ 5.7% (elevated), nondiabetic participants with <5.0% (low) and diabetic participants all compared with nondiabetic participants with 5.0-5.6% (normal). We ascertained 2,349 incident cancer cases and 887 cancer deaths. Compared with nondiabetic women with normal glycated hemoglobin, nondiabetic women with elevated values had an increased risk of cancer incidence (HR:1.24; 95% CI:1.07,1.44) and mortality (HR:1.58; 95% CI:1.23,2.05) as did diabetic women (incidence, HR:1.30; 95% CI:1.06,1.60, mortality, HR:1.96; 95% CI:1.40,2.76). Nondiabetic women with low values also had increased risk. Diabetic women with good glycemic control (<7.0%) had a lower cancer risk than those with higher values. Glycated hemoglobin in nondiabetic and diabetic men, and diabetes were not statistically significantly associated with total cancer risk. Our findings support the hypothesis that chronic hyperglycemia, even in the nondiabetic range, increases cancer risk in women. Maintaining normal glycated hemoglobin overall, and good glycemic control among diabetic adults, may reduce the burden of cancer, especially in women.

Abstract
Cardiovascular disease accounts for nearly 70% of morbidity and mortality in patients with diabetes mellitus. Strides made in diabetes care have indeed helped prevent or reduce the burden of microvascular complications in both type 1 and type 2 diabetes. However, the same cannot be said about macrovascular disease in diabetes. Several prospective trials so far have failed to provide conclusive evidence of the superiority of glycemic control in reducing macrovascular complications or death rates in people with advanced disease or those with long duration of diabetes. There are trends that suggest that benefits are restricted to those with lesser burden and shorter duration of disease. Furthermore, it is also suggested that benefits might accrue but it would take a longer time to manifest. Clinicians are faced with the challenge to decide how to triage patients for intensified care vs less intense care. This review focuses on evidence and attempts to provide a balanced view of the literature that has radically affected how physicians treat patients with macrovascular disease. It also takes cognizance of the fact that the natural course of the disease may be changing as well, possibly related to better overall awareness and possibly improved access to information about better individual healthcare. The review further takes note of some hard held notions about the pathobiology of the disease that must be interpreted with caution in light of new and emerging data. In light of recent developments ADA and EASD have taken step to provide some guidance to clinicians through a joint position statement. A lot more research would be required to figure out how best to manage macrovascular disease in diabetes mellitus. Glucocentric stance would need to be reconsidered, and attention paid to concurrent multifactorial interventions that seem to be effective in reducing vascular outcomes.

Abstract
OBJECTIVE To study the prognosis of people with newly diagnosed type 2 diabetes as per the American Diabetes Association (ADA) 2010 definition but without diabetes as per the ADA 2009 definition. RESEARCH DESIGN AND METHODS A total of 2,002 participants of the Ludwigshafen Risk and Cardiovascular Health (LURIC) study without a history of diabetes were studied. RESULTS During the follow-up of a mean duration ± SD of 7.7 ± 2.0 years, 346 people died (202 cardiovascular deaths). Subjects with type 2 diabetes as per the ADA 2009 definition (n = 468) had significantly increased all-cause and cardiovascular mortality compared with people without diabetes as per the ADA 2010 definition (both P ≤ 0.003). Subjects with type 2 diabetes as per the ADA 2010 definition but without diabetes as per the ADA 2009 definition (n = 150) were at significantly increased risk to die of cardiovascular diseases (P = 0.029). CONCLUSIONS Use of the ADA 2010 diabetes definition may be instrumental in improving cardiovascular risk stratification in people undergoing coronary angiography.
