Abdi A, Kohansal K, Khalili D, Azizi F, Hadaegh F. The difference between 2-hour post-challenge and fasting plasma glucose associates with the risk of cardiovascular disease in a normoglycemic population: the Tehran lipid and glucose study. Nutr Metab (Lond) 2024; 21:10. [PMID: 38389086 PMCID: PMC10882815 DOI: 10.1186/s12986-024-00782-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 02/06/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND Elevated fasting plasma glucose (FPG) and 2-hour post-challenge glucose (2hPG) levels are known to be independent risk factors for cardiovascular disease (CVD). However, there is limited data on the association of the difference between these measures and the risk of CVD. This study aims to investigate this association in normoglycemic Iranian adults, particularly in those with low-normal FPG levels. METHODS This prospective cohort study included 4,594 30-65-year-old participants from the Tehran Lipid and Glucose Study. Using multivariable Cox proportional hazards regression models adjusting for age, sex, body mass index, hypertension, hypercholesterolemia, smoking, education level and FPG, hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated for the association between 2hPG-FPG, both as continuous and categorical variables, and the CVD risk. Analyses of receiver operating characteristic curves were undertaken to determine the optimal 2hPG-FPG cut-off value. RESULTS During a median of 17.9 years of follow-up, 459 CVD events occurred. A one-unit increase in 2hPG-FPG was significantly associated with an elevated risk of cardiovascular disease in both normoglycemic (HR 1.10, 95% CI (1.01-1.19)) and low-normal FPG individuals (HR 1.16, 95% CI (1.04-1.30)); this association resisted adjustment for Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) among normoglycemic individuals. However, those with 2hPG levels greater than FPG levels had a non-significant increased risk of incident CVD compared to those with 2hPG levels of less than or equal to FPG, with corresponding HR values of 1.18 (95% CI: 0.95-1.46) in normoglycemic and 1.32 (95% CI: 0.98-1.79) in low-normal FPG, respectively. For incident CVD, the optimal cut-off value for the 2hPG-FPG was found to be 1.06 mmol/L, which was applicable for both normoglycemic and low FPG populations; using this criterion, the corresponding risks for incident CVD were 1.36 (95% CI: 1.12-1.64) and 1.57 (95% CI: 1.22-2.03), respectively. CONCLUSIONS The difference between 2hPG and FPG levels within the normoglycemic range is related to an increased risk of CVD, an issue that was independent of HOMA-IR. A cut-off point for 2hPG-FPG > 1.06 mmol/L may stratify persons at higher risk. These findings were particularly notable in those with low-normal FPG.

Abstract
BACKGROUND Significant racial and gender differences exist in the prevalence of CVD in the United States. The goal of this study is to evaluate the prevalence of CVD among Black American women, the relationship between CVD and some medical conditions, and significant sociodemographic factors. METHODS The researchers in this study used data from four cycles of the NHANES, carried out by the NCHS. 2011 to 2012, 2013 to 2014, 2015 to 2016, and 2017 to 2020 were the cycles that were chosen. The researchers used the survey package in the R programming language to examine the data. RESULTS People with CVD problems 20 years of age and older were included in the analyses. Black American women experienced a considerable prevalence of CVD from 2011 to 2020. These women were more likely to report having completed no more schooling than the ninth grade, being widowed/divorced/separated, and having undergone a hysterectomy, as well as having a history of diabetes, asthma, obesity, arthritis, and depression. Black American women with CVD had a 3.8-fold increased risk of diabetes and a 5.6-fold increased risk of arthritis. CONCLUSION This study shows that Black American women with CVD are more likely to have chronic illnesses such as hysterectomy, diabetes, asthma, obesity, arthritis, and depression. Black American women's cardiovascular risk profiles can be updated using the data from this study.

Abstract
Background Cardiovascular diseases are the first leading cause of mortality in the world. Practical guidelines recommend an accurate estimation of the risk of these events for effective treatment and care. The UK Prospective Diabetes Study (UKPDS) has a risk engine for predicting CHD risk in patients with type 2 diabetes, but in some countries, it has been shown that the risk of CHD is poorly estimated. Hence, we assessed the external validity of the UKPDS risk engine in patients with type 2 diabetes identified in the national diabetes program in Iran. Methods The cohort included 853 patients with type 2diabetes identified between March 21, 2007, and March 20, 2018 in Lorestan province of Iran. Patients were followed for the incidence of CHD. The performance of the models was assessed in terms of discrimination and calibration. Discrimination was examined using the c-statistic and calibration was assessed with the Hosmer-Lemeshow χ2 statistic (HLχ2) test and a calibration plot was depicted to show the predicted risks versus observed ones. Results During 7464.5 person-years of follow-up 170 first Coronary heart disease occurred. The median follow-up was 8.6 years. The UKPDS risk engine showed moderate discrimination for CHD (c-statistic was 0.72 for 10-year risk) and the calibration of the UKPDS risk engine was poor (HLχ2 = 69.9, p < 0.001) and the UKPDS risk engine78% overestimated the risk of heart disease in patients with type 2 diabetes identified in the national diabetes program in Iran. Conclusion This study shows that the ability of the UKPDS Risk Engine to discriminate patients who developed CHD events from those who did not; was moderate and the ability of the risk prediction model to accurately predict the absolute risk of CHD (calibration) was poor and it overestimated the CHD risk. To improve the prediction of CHD in patients with type 2 diabetes, this model should be updated in the Iranian diabetic population.

Abstract
Chronic diseases such as cardiovascular disease (CVD), atherosclerosis, chronic liver disease, and neurodegenerative diseases are major causes of mortality. These diseases have gained much attention due to their complications, and therefore novel approaches with fewer side effects are an important research topic. Free radicals and oxidative stress are involved in the molecular mechanisms of several diseases. Antioxidants can scavenge free radicals and mitigate their adverse effects. One of the most important antioxidant enzymes are paraoxonases (PONs). These enzymes perform a wide range of physiological activities ranging from drug metabolism to detoxification of neuroleptics. Paraoxonase-1 (PON1) is produced in the liver and then transferred to the bloodstream. It has been demonstrated that PON1 could have beneficial effects in numerous diseases such as atherosclerosis, CVD, diabetes mellitus, and neurodegenerative diseases by modulating relevant signalling pathways involved in inflammation and oxidative stress. These pathways include peroxisome proliferator-activated receptor gamma (PPAR-γ) and protein kinase B/nuclear factor kappa-light-chain-enhancer of activated B cells (AKT/NF-κB)-dependent signalling pathways. Increasing PON1 could potentially have protective effects and reduce the incidence of various diseases by modulating these signalling pathways. Several studies have reported that dietary factors are able to modulate PON1 expression and activity. This review aimed at summarizing the state of the art on the effects of dietary phytochemicals on PON1 enzyme activity and the relevant signalling pathways in different diseases.

Abstract
OBJECTIVES The aim of this study was to identify risk factors of in-hospital mortality among diabetic patients infected with COVID-19. STUDY DESIGN This is a retrospective cohort study. METHODS Using logistic regression analysis, the independent association of potential prognostic factors and COVID-19 in-hospital mortality was investigated in three models. Model 1 included demographic data and patient history; model 2 consisted of model 1, plus vital signs and pulse oximetry measurements at hospital admission; and model 3 included model 2, plus laboratory test results at hospital admission. The odds ratios (ORs) and 95% confidence intervals (95% CIs) were reported for each predictor in the different models. Moreover, to examine the discriminatory powers of the models, a corrected area under the receiver-operating characteristic curve (AUC) was calculated. RESULTS Among 560 patients with diabetes (men = 291) who were hospitalised for COVID-19, the mean age of the study population was 61.8 (standard deviation [SD] 13.4) years. During a median length of hospitalisation of 6 days, 165 deaths (men = 93) were recorded. In model 1, age and a history of cognitive impairment were associated with higher mortality; however, taking statins, oral antidiabetic drugs and beta-blockers was associated with a lower risk of mortality (AUC = 0.76). In model 2, adding the data for respiratory rate (OR 1.07 [95% CI 1.00-1.14]) and oxygen saturation (OR 0.95 [95% CI 0.92-0.98]) slightly increased the AUC to 0.80. In model 3, the data for platelet count (OR 0.99 [95% CI 0.99-1.00]), lactate dehydrogenase (OR 1.002 [95% CI 1.001-1.003]), potassium (OR 2.02 [95% CI 1.33-3.08]) and fasting plasma glucose (OR 1.04 [95% CI 1.02-1.07]) significantly improved the discriminatory power of the model to AUC 0.86 (95% CI 0.83-0.90). CONCLUSIONS Among patients with type 2 diabetes, a combination of past medical and drug history and pulse oximetry data, with four non-expensive laboratory measures, was significantly associated with in-hospital COVID-19 mortality.

Relationship between Indices of Vascular Function and Presence of Overt Cardiovascular Disease among Persons with Poorly Controlled Type 2 Diabetes. J Cardiovasc Dev Dis 2021; 8:jcdd8120185. [PMID: 34940540 PMCID: PMC8704649 DOI: 10.3390/jcdd8120185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 12/12/2021] [Accepted: 12/13/2021] [Indexed: 11/16/2022] Open
Abstract
The aim of this study was to assess the factors associated with impaired vascular function in patients with poorly controlled type 2 diabetes (DM2) with and without overt cardiovascular disease (CVD). Ninety-five patients with DM2 and poor glycemic control were recruited and divided into two groups: Group 1, with known CVD (n = 38), and Group 2, without CVD (n = 57). Patients in Group 2 were further subdivided into those with short (<5 years, group 2b) and long (>5 years, group 2a) diabetes duration. Subclinical markers of atherosclerosis were assessed. Glycemic control was similar in the two groups (HbA1c: 9.2% (1.5) vs. 9.4% (1.8), p = 0.44). In Group 1, lower FMD (3.13 (2.16)% vs. 4.7 (3.4)%, p < 0.05) and higher cIMT (1.09 (0.3) mm vs. 0.96 (0.2) mm, p < 0.05) was seen compared with Group 2, whereas PWV was similar (12.1 (3.4) vs. 11.3 (3.0) m/s, p = 0.10). Patients in Group 2b had significantly lower PWV and cIMT and higher FMD compared to Group 1 (p < 0.05). Among patients with poorly controlled T2D, more pronounced vascular dysfunction was present in those with overt macrovascular disease. In patients with T2D without known CVD, vascular dysfunction was associated with disease duration. The use of vascular indices for cardiovascular risk stratification in patients with T2D requires further study.

Abstract
OBJECTIVE We examined diabetes mellitus (DM) as a cardiovascular disease (CVD) risk equivalent based on diabetes severity and other CVD risk factors. RESEARCH DESIGN AND METHODS We pooled 4 US cohorts (ARIC, JHS, MESA, FHS-Offspring) and classified subjects by baseline DM/CVD. CVD risks between DM+/CVD- vs. DM-/CVD+ were examined by diabetes severity and in subgroups of other CVD risk factors. We developed an algorithm to identify subjects with CVD risk equivalent diabetes by comparing the relative CVD risk of being DM+/CVD- vs. DM-/CVD+. RESULTS The pooled cohort included 27,730 subjects (mean age of 58.5 years, 44.6% male). CVD rates per 1000 person-years were 16.5, 33.4, 43.2 and 71.4 among those with DM-/CVD-, DM+/CVD-, DM-/CVD+ and DM+/CVD+, respectively. Compared with those with DM-/CVD+, CVD risks were similar or higher for those with HbA1c ≥ 7%, diabetes duration ≥10 years, or diabetes medication use while those with less severe diabetes had lower risks. Hazard ratios (95%CI) for DM+/CVD- vs. DM-/CVD+ were 0.96(0.86-1.07), 0.97(0.88-1.07), 0.96(0.82-1.13), 1.18(0.98-1.41), 0.93(0.85-1.02) and 1.00(0.89-1.13) among women, white race, age <55 years, triglycerides ≥2.26 mmol/L, hs-CRP ≥ 2 mg/L and eGFR<60 mL/min/1.73m2, respectively. In DM+/CVD- group, 19.1% had CVD risk equivalent diabetes with a lower risk score but a higher observed CVD risk. CONCLUSION Diabetes is a CVD risk equivalent in one-fifth of CVD-free adults living with diabetes. High HbA1c, long diabetes duration, and diabetes medication use were predictors of CVD risk equivalence. Diabetes is a CVD risk equivalent for women, white people, those of younger age, with higher triglycerides or CRP, or reduced kidney function.

[PMID: 34344986 PMCID: PMC8333266 DOI: 10.1038/s41598-021-95210-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Accepted: 07/20/2021] [Indexed: 02/07/2023] Open
Abstract
Sudden cardiac death (SCD) is described as death within one hour, if observed, from the onset of symptoms, and within 24 h of being alive and well if not observe. Study population includes 3705 men and 4446 women, aged ≥ 30 years. Multivariable Cox proportional hazard models were used to determine the risk factors associated with SCD. After a median follow-up of 17.9 years, 244 SCD (165 in males) occurred. The age-standardized incidence rate (95% confidence intervals (CI)) of SCD was 2.3 (2.1–2.7) per 1000 person-year. Current smoking [Hazard ratio (HR): 2.43, 95% CI: 1.73–3.42], high waist circumference [1.49: 1.04–2.12], hypertension [1.39: 1.05–1.84], type 2 diabetes mellitus [2.78: 2.09–3.69], pulse rate ≥ 90 beats per/minute [1.72: 1.22–2.42] and prevalent cardiovascular disease [1.75: 1.26–2.45] were significant risk factors. The corresponding population attributed fractions (PAF) were 14.30, 16.58, 14.03, 19.60, 7.62, and 8.30, respectively. Being overweight [0.58: 0.40–0.83] and obese [0.61: 0.38–0.98] decreased the risk of SCD. After excluding known diabetes cases from our data analysis, the newly diagnosed diabetes still showed an HR of 2.0 (1.32–3.00) with a PAF of 7.15% in the full adjustment model. To deal with sudden death as a catastrophic outcome, multi-component strategies by policy health makers are suggested.

Abstract
OBJECTIVE We investigated the cumulative burden and linear rates of change of major metabolic risk factors (MRFs) among Iranian adults in whom type 2 diabetes did and did not develop. RESEARCH DESIGN AND METHODS We included 7,163 participants (3,069 men) aged 20-70 years at baseline with at least three examinations during 1999-2018. Individual growth curve modeling was used for data analysis. Statistical interactions for sex by diabetes status were adjusted for age, family history of diabetes, smoking status, and physical activity level. RESULTS Study sample included 743 (316 men) new case subjects with diabetes. In both men and women, compared with individuals in whom diabetes did not develop, individuals in whom diabetes developed had a higher burden of all MRFs and a greater rate of change in BMI, fasting plasma glucose (FPG), systolic blood pressure (SBP), and diastolic blood pressure; however, the differences in burden and rate of change between those who did and did not develop diabetes were greater in women than in men. During the transition to diabetes, women experienced more adverse change in BMI, FPG, triglyceride, and HDL cholesterol (HDL-C) (diabetes-sex interaction P values <0.05) and faster rates of change in BMI, FPG, HDL-C, and total cholesterol (interaction P values <0.01) and SBP (interaction P = 0.055) than men. CONCLUSIONS The greater exposure of women to and burden of MRFs before onset of diabetes may have implications for implementing sex-specific strategies in order to prevent or delay diabetes complications.

Sex-specific prevalence of coronary heart disease among Tehranian adult population across different glycemic status: Tehran lipid and glucose study, 2008-2011. BMC Public Health 2020; 20:1510. [PMID: 33023566 PMCID: PMC7539419 DOI: 10.1186/s12889-020-09595-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 09/22/2020] [Indexed: 02/07/2023] Open
Abstract
Background Coronary heart disease (CHD) is one of the leading causes of death. Alarmingly Iranian populations had a high rank of CHD worldwide. The current study aimed to assess the prevalence of CHD across different glycemic categories. Methods This study was conducted on 7718 Tehranian participants (Men = 3427) aged ≥30 years from 2008 to 2011. They were categorized based on glycemic status. The prevalence of CHD was calculated in each group separately. CHD was defined as hospital records adjudicated by an outcome committee. The association of different glycemic categories with CHD was calculated using multivariate logistic regression, compared with normal fasting glucose /normal glucose tolerance (NFG/NGT) group as reference. Results The age-standardized prevalence of isolated impaired fasting glucose (iIFG), isolated impaired glucose tolerance (iIGT), both impaired fasting glucose and impaired glucose tolerance (IFG/IGT), newly diagnosed diabetes mellitus (NDM), and known diabetes mellitus (KDM) were 14.30% [95% confidence interval (CI): 13.50–15.09], 4.81% [4.32–5.29], 5.19% [4.71–5.67], 5.79% [5.29–6.28] and 7.72% [7.17–8.27], respectively. Among a total of 750 individuals diagnosed as cases of CHD (398 in men), 117 (15.6%), 453 (60.4%), and 317 (42.3%) individuals had a history of myocardial infarction (MI), cardiac procedure, and unstable angina, respectively. The age-standardized prevalence of CHD for the Tehranian population was 7.71% [7.18–8.24] in the total population, 8.62 [7.81–9.44] in men and 7.19 [6.46–7.93] in women. Moreover, among diabetic participants, the age-standardized prevalence of CHD was 13.10 [9.83–16.38] in men and 10.67 [8.90–12.44] in women, significantly higher than corresponding values for NFG/NGT and prediabetic groups. Across six levels of glycemic status, CHD was associated with IFG/IGT [odds ratio (OR) and 95% CI: 1.38 (1.01–1.89)], NDM [1.83 (1.40–2.41)], and KDM [2.83 (2.26–3.55)] groups, in the age- and sex-adjusted model. Furthermore, in the full-adjusted model, only NDM and KDM status remained to be associated with the presence of CHD by ORs of 1.40 (1.06–1.86) for NDM and 1.91 (1.51–2.43) for KDM. Conclusion The high prevalence of CHD, especially among diabetic populations, necessitates the urgent implementation of behavioral interventions in the Tehranian population, according to evidence-based guidelines for the clinical management of diabetic patients.

Abstract
OBJECTIVE Although glucose abnormality status (GAS), prior coronary artery disease (CAD), and other traditional risk factors affect the incidence of subsequent CAD, their impact in the same cohort has been scantly studied. RESEARCH DESIGN AND METHODS We analyzed data from a nationwide claims database in Japan that was accumulated during 2008-2016 involving 138,162 men aged 18-72 years. Participants were classified as having normoglycemia, borderline glycemia, or diabetes mellitus (DM) with prior CAD (CAD+) or without prior CAD (CAD-). Cox regression model identified variables related to the incidence of CAD. RESULTS Among CAD-, management of traditional risks differed from those with and without subsequent CAD events. On the other hand, such differences were weaker in borderline glycemia and DM CAD+, and the influence of traditional risk factors on subsequent CAD was not observed. Cox regression model showed that borderline glycemia and DM confer approximately 1.2- and 2.8-fold excess risks of CAD, respectively, compared with CAD- with normoglycemia. CAD+ confers approximately a 5- to 8-fold increased risk. The impacts of DM and prior CAD additively reached a hazard ratio (HR) of 15.74 (95% confidence interval [CI]: 11.82-21.00). However, the HR in those with borderline glycemia and CAD+ was 7.20 (95% CI: 5.01-10.34), which was not different from those with normoglycemia and CAD+. CONCLUSION Control status of traditional risk factors and impact on subsequent CAD differ among categories of glycemic status with and without prior CAD. Individualizing treatment strategies is needed in consideration of risk factors, such as GAS and CAD+.

Abstract
BACKGROUND Several publications and guidelines designate diabetes mellitus (DM) as a coronary artery disease (CAD) risk equivalent. The aim of this investigation was to examine DM cardiac risk equivalence from the perspective of stress SPECT myocardial perfusion imaging (MPI). METHODS AND RESULTS We examined cardiovascular outcomes (cardiac death or nonfatal MI) of 17,499 patients referred for stress SPECT-MPI. Patients were stratified into four categories: non-DM without CAD, non-DM with CAD, DM without CAD, and DM with CAD, and normal or abnormal perfusion. Cardiac events occurred in 872 (5%), with event-free survival best among non-DM without CAD, worst in DM with CAD, and intermediate in DM without CAD, and non-DM with CAD. After multivariate adjustment, risk remained comparable between DM without CAD and non-DM with CAD [AHR 1.0 (95% CI 0.84-1.28), P =0.74]. Annualized event rates for normal subjects were 1.4% and 1.6% for non-DM with CAD and DM without CAD, respectively (P = 0.48) and 3.5% (P = 0.95) for both abnormal groups. After multivariate adjustment, outcomes were comparable within normal [AHR 1.4 (95% CI 0.98-1.96) P = 0.06] and abnormal [AHR 1.1 (95% CI 0.83-1.50) P = 0.49] MPI. CONCLUSIONS Diabetic patients without CAD have comparable risk of cardiovascular events as non-diabetic patients with CAD after stratification by MPI results. These findings support diabetes as a CAD equivalent and suggest that MPI provides additional prognostic information in such patients.

Abstract
CONTEXT We summarized findings from Tehran lipid and glucose study (TLGS) about different aspects of type 2 diabetes (T2D) over the span of nearly 2 decades. EVIDENCE ACQUISITION A review was undertaken to retrieve papers related to all aspects of T2D from the earliest date available up to January 30, 2018. RESULTS An annual crude incidence rate of 10 per 1000 person-years of follow-up was found for T2D in adult participants. Overall incidence rate of pre-diabetes/T2D was 36.3 per 1000 person-years or about 1% each year among youth. Diabetes was associated with increased risk of CVD [hazard ratio (HR): 1.86, 95% confidence interval (95% CI): 1.57 - 2.27] and mortality [HR: 2.56; 95% CI: 2.08 - 3.16] in the total population. Compared with non-diabetic men and women, their diabetic counterparts survived 1.4 and 0.7 years shorter, respectively, during 15 years of follow-up. Wrist circumference, hyperinsulinaemia, 25-hydroxy vitamin D and increase in alanin aminotranferase provided incremental prognostic information beyond the traditional risk factors for incident T2D in adults. Using decision tree algorithms, a number of high risk groups were found for incident T2D. A probability of 84% was found for incidence of T2D among a group of men with fasting plasma glucose (FPG) > 5.3 mmol/L and waist to height ratio (WHtR) > 0.56, and women with FPG > 5.2 mmol/L and WHtR > 0.56. CONCLUSIONS Original TLGS studies have contributed greatly to clarify important evidence regarding the epidemiology and risk factors for T2D among Iranian population.

Optimal cut-points of different anthropometric indices and their joint effect in prediction of type 2 diabetes: results of a cohort study. BMC Public Health 2018; 18:691.

Abstract
Background To determine the anthropometric indices that would predict type 2 diabetes (T2D) and delineate their optimal cut-points. Methods In a cohort study, 7017 Iranian adults, aged 20–60 years, free of T2D at baseline were investigated. Using Cox proportional hazard models, hazard ratios (HRs) for incident T2D per 1 SD change in body mass index (BMI), waist circumference (WC), waist to height ratio (WHtR), waist to hip ratio (WHR), and hip circumference (HC) were calculated. The area under the receiver operating characteristics (ROC) curves (AUC) was calculated to compare the discriminative power of anthropometric variables for incident T2D. Cut-points of each index were estimated by the maximum value of Youden’s index and fixing the sensitivity at 75%. Using the derived cut-points, joint effects of BMI and other obesity indices on T2D hazard were assessed. Results During a median follow-up of 12 years, 354 men, and 490 women developed T2D. In both sexes, 1 SD increase in anthropometric variables showed significant association with incident T2D, except for HC in multivariate adjusted model in men. In both sexes, WHtR had the highest discriminatory power while HC had the lowest. The derived cut-points for BMI, WC, WHtR, WHR, and HC were 25.56 kg/m2, 89 cm, 0.52, 0.91, and 96 cm in men and 27.12 kg/m2, 87 cm, 0.56, 0.83, and 103 cm in women, respectively. Assessing joint effects of BMI and each of the obesity measures in the prediction of incident T2D showed that among both sexes, combined high values of obesity indices increase the specificity for the price of reduced sensitivity and positive predictive value. Conclusions Our derived cut-points differ between both sexes and are different from other ethnicities.

Abstract
BACKGROUND To examine the trend of cardiovascular diseases (CVD) risk factors among a Middle Eastern population with prevalent CVD during a median follow up of 12 years. METHODS Patients with prevalent CVD (n = 282, men = 167), with a mean age of 60.76 years were evaluated in four study phases of the TLGS (Tehran lipid glucose study), 2002-2005, 2005-2008, 2008-2011, and 2011-2014. Trends of CVD risk factors were estimated using generalized estimation equation (GEE) models, by adjusting for gender, age and propensity scores. RESULT The adjusted prevalence of general and central adiposity, diabetes and physical inactivity at baseline was 25.18, 60.14, 25.03 and 43.74%, respectively and had increasing trends during the study period, reaching 41.32, 66.74, 43.20 and 50.32%, respectively, at the last visit. Although systolic, but not diastolic blood pressure, decreased from 134.88 to 129.86 mmHg, the prevalence of hypertension did not decrease (64.21% vs 68%, p value = 0.326). The prevalence of low high density lipoprotein cholesterol (HDL-C), hypertriglyceridemia and high non-HDL-C at baseline was 74.54, 59.89 and 96.53%, respectively, and showed improved trends reaching 44.87, 47.12 and 96.06% respectively; however, the favorable trend was not observed for high low density cholesterol. Significant increasing trends were observed in the consumption of anti-hypertensive, lipid and glucose lowering medications, but not for aspirin. The prevalence of current smoking (11.05 vs 16.83%, p value = 0.042) and chronic kidney disease (44.16 vs 51.65%, p value = 0.054) increased during follow up. CONCLUSION Except for lipid profile status, dangerous trends for other CVD risk factors were demonstrated among CVD patients, which can be a harbinger for high rates of CVD mortality; these findings highlight the need for urgent implementation of multicomponent interventions to control CVD risk factors among these patients.

Impact Of Hypertension versus Diabetes on Cardiovascular and All-cause Mortality in Iranian Older Adults: Results of 14 Years of Follow-up. Sci Rep 2017; 7:14220. [PMID: 29079827 PMCID: PMC5660198 DOI: 10.1038/s41598-017-14631-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Accepted: 10/12/2017] [Indexed: 12/25/2022] Open
Abstract
To evaluate the joint effect of hypertension (HTN) and diabetes (DM) on coronary heart disease (CHD), and stroke event, all-cause, and cardiovascular disease (CVD) mortality in Middle Eastern older adults, 2747 people (1436 women) aged ≥ 50 years, free of CVD at baseline, were categorized into four groups (HTN−/DM−, HTN+/DM−, HTN−/DM+, HTN+/DM+). Multivariate Cox proportional hazard models were run for different outcomes. To compare the impact of HTN versus DM, HTN+/DM− was considered as reference. In a median of 13.9 years, incidence rate of CHD, and stroke event, all-cause and CVD mortality in total population were 19.0, 4.7, 13.5, and 6.4 per 1000 person-years, respectively. The multivariate sex-adjusted hazard ratios (HRs) of HTN−/DM+ for CHD, stroke, all-cause mortality and CVD mortality were 1.19 (confidence interval (CI): 0.9–1.57), 1.07 (CI: 0.63–1.82), 1.62 (CI: 1.2–2.18), and 1.28 (CI: 0.83–1.97); the corresponding HRs for HTN+/DM+ were 1.96 (CI: 1.57–2.46), 1.66 (CI: 1.1–2.52), 2.32 (CI: 1.8–2.98), and 2.6 (CI: 1.85–3.65) respectively. The associations between HTN/DM status with stroke incidence and all-cause mortality were stronger among men than in women (P for interaction <0.05). Compared to HTN+/DM−, HTN−/DM+ increases all-cause mortality by 62%, however, they are not considerably different regarding CHD, stroke incidence and CVD mortality.

[PMID: 28848610 PMCID: PMC5556326 DOI: 10.5812/ijem.42713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2016] [Revised: 02/27/2017] [Accepted: 04/09/2017] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND High-risk individuals for CHD could be diagnosed by some non-invasive and low-priced techniques such as Minnesota ECG coding and rose angina questionnaire (RQ). OBJECTIVES The present study aimed at determining the risk of incident CHD according to ECG and RQ besides diabetes and other metabolic risk factors in our population. METHODS Participants comprised of 5431 individuals aged ≥ 30 years within the framework of Tehran lipid and glucose study. Based on their status on history of CHD, ECG, and RQ at baseline, all participants were classified to 5 following groups: (1) History-Rose-ECG- (the reference group); (2) History-Rose+ECG-; (3) History-Rose-ECG+; (4) History-Rose+ECG+; and (5) History+. We used Cox regression model to find the role of ECG and RQ on CHD, independent of other risk factors. RESULTS Overall, 562 CHD events were detected during the median of 10.3 years follow-up. CHD incidence rates were 55.9 and 9.09 cases per 1000 person-year for participants with and without history of CHD, respectively. Hazard ratios (HRs) (95% CIs) were 4.11 (3.27 - 5.11) for History + and 2.18 (1.63 - 2.90), 1.92 (1.47 - 2.51), and 2.48 (1.46 - 4.20) for History-Rose+ECG-, History-Rose-ECG+, and History-Rose+ECG+, respectively. RQ and ECG had the same HRs as high as those for hypertension and hypercholesterolemia; however, diabetes showed statistically and clinically more effects on CVD than RQ and ECG. CONCLUSIONS RQ in general and, ECG especially in asymptomatic patients, were good predictors for CHD events in both Iranian males and females; however, their predictive powers were lower than that of diabetes.

Prevalence of cardio-metabolic risk factors in a nationally representative sample of Iranian adolescents: The CASPIAN-III Study. J Cardiovasc Thorac Res 2017; 9:12-20. [PMID: 28451083 PMCID: PMC5402022 DOI: 10.15171/jcvtr.2017.02] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2016] [Accepted: 02/17/2017] [Indexed: 12/28/2022] Open
Abstract
Introduction: The aim of the present study is to explore the prevalence and mean of cardiometabolic
risk factors and liver enzymes of Iranian adolescents living in regions with different
socioeconomic status (SES). To the best of our knowledge this is the first study reporting these
data at sub-national level in Iran.
Methods: This multi-centric study was performed in 2009-2010 on a stratified multi-stage
probability sample of 5940 students aged 10-18 years, living in urban and rural areas of 27
provinces of Iran. Trained healthcare professionals measured anthropometric indices, systolic
and diastolic blood pressures (SBP, DBP) according to standard protocols. Fasting venous blood
was examined for fasting blood sugar (FBS), lipid profile and liver enzymes including alanine
aminotransferase (ALT) and aspartate aminotransferase (AST). We classified the country into
four sub-national regions based on criteria of the combination of geography and SES. Mean and
frequency of risk factors were compared across these regions.
Results: The mean of body mass index had linear rise with increase in the regions’ SES (P for trend <0.001). The mean levels of DBP, total cholesterol (TC), high-density lipoproteincholesterol (HDL-C), triglycerides (TG), FBS, ALT, and AST had linear association with regions’ SES in the whole population and in both genders (P for trend < 0.05), whereas the corresponding figure was statistically significant for the mean SBP only in girls (P for trend: 0.03) and for the mean of LDL-C in the whole population and in boys (P for trend <0.001). In total and in both genders, there was an escalating trend in the prevalence of elevated FBS, TC and liver enzymes, low HDL-C, and metabolic syndrome by increase in the SES of the region(P for trend <0.01).
Conclusion: This study proposes that in addition to national health policies on preventing
cardiometabolic risk factors, specific interventions should be considered according to the regional
SES level.

Risk Factors for Incidence of Cardiovascular Diseases and All-Cause Mortality in a Middle Eastern Population over a Decade Follow-up: Tehran Lipid and Glucose Study. PLoS One 2016; 11:e0167623. [PMID: 27930696 PMCID: PMC5145170 DOI: 10.1371/journal.pone.0167623] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Accepted: 11/17/2016] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND To examine the association between potentially modifiable risk factors with cardiovascular disease (CVD) and all-cause mortality and to quantify their population attributable fractions (PAFs) among a sample of Tehran residents. METHODS Overall, 8108 participants (3686 men) aged≥30 years, were investigated. To examine the association between risk factors and outcomes, multivariate sex-adjusted Cox proportional hazard regression analysis were conducted, using age as time-scale in two models including general/central adiposity: 1)adjusted for different independent variables including smoking, education, family history of CVD and sex for both outcomes and additionally adjusted for prevalent CVD for all-cause mortality 2)further adjusted for obesity mediators (hypertension, diabetes, lipid profile and chronic kidney disease). Separate models were used including either general or central adiposity. RESULTS During median follow-up of >10 years, 827 first CVD events and 551 deaths occurred. Both being overweight (hazard ratio (HR), 95%CI: 1.41, 1.18-1.66, PAF 13.66) and obese (1.51, 1.24-1.84, PAF 9.79) played significant roles for incident CVD in the absence of obesity mediators. Predicting CVD, in the presence of general adiposity and its mediators, significant positive associations were found for hypercholesterolemia (1.59, 1.36-1.85, PAF 16.69), low HDL-C (1.21, 1.03-1.41, PAF 12.32), diabetes (1.86, 1.57-2.27, PAF 13.87), hypertension (1.79, 1.46-2.19, PAF 21.62) and current smoking (1.61, 1.34-1.94, PAF 7.57). Central adiposity remained a significant positive predictor, even after controlling for mediators (1.17, 1.01-1.35, PAF 7.55). For all-cause mortality, general/central obesity did not have any risk even in the absence of obesity mediators. Predictors including diabetes (2.56, 2.08-3.16, PAF 24.37), hypertension (1.43, 1.11-1.84, PAF 17.13), current smoking (1.75, 1.38-2.22, PAF 7.71), and low education level (1.59, 1.01-2.51, PAF 27.08) were associated with higher risk, however, hypertriglyceridemia (0.83, 0.68-1.01) and being overweight (0.71, 0.58-0.87) were associated with lower risk. CONCLUSIONS Modifiable risk factors account for more than 70% risk for both CVD and mortality events.

Abstract
BACKGROUND To identify risk factors for cardiovascular disease (CVD) and mortality events in patients with type 2 diabetes and to calculate their population attributable fraction among a representative Iranian population. METHODS A total of 1198 patients with type 2 diabetes (504 men and 694 women), aged ≥30 years, without prevalent CVD, with a median follow-up of 10 years were included in current study. To examine the association between risk factors and their outcomes, multivariate sex-adjusted Cox proportional hazard regression models were used. RESULTS During the study, 281 and 172 participants experienced CVD and all-cause mortality events, respectively. Regarding CVD events, fasting plasma glucose (FPG) level of 7.22-<10 mmol/L [hazard ratio (HR): 1.46, 95% CI 1.12-1.96], FPG level ≥10 mmol/L (HR 2.04, 1.53-2.72), hypertension (HR 1.65, 1.28-2.13), hypercholesterolaemia (HR 1.96, 1.40-2.75) and high waist to hip ratio (HR 1.30, 0.99-1.70; p = 0.051) were significant predictors, and corresponding population attributable fractions were 9.76, 17.84, 23.26, 41.63 and 14.76%, respectively. Considering all-cause mortality events, hypertension (HR 1.70, 1.23-2.36), FPG level ≥10 mmol/L (HR 2.31, 1.55-3.20) and smoking (HR 1.45, 1.03-2.04) were significant predictors, and corresponding population attributable fractions were 25.81, 20.88 and 11.18%, respectively. Meanwhile, being overweight or obese was associated with lower all-cause and CVD mortality events. CONCLUSIONS Among modifiable risk factors in patients with type 2 diabetes, hypercholesterolaemia and central adiposity for CVD, smoking for mortality events and hypertension and poor glycaemic control for both outcomes need to be paid most attention by healthcare professionals.

Abstract
INTRODUCTION To examine the associations between smoking and cardiovascular disease (CVD) / coronary heart disease (CHD) and all-cause mortality events in men with and without type 2 diabetes (T2D) in a Middle Eastern cohort during a median follow-up of 12 years. METHODS The study population included 2230 subjects aged ≥ 40 years, free from CVD, comprised of 367 participants with diabetes (21.2% current smokers) and 1863 without (27.3% current smokers). Multivariate Hazard ratios (HR) and 95% confidence intervals (CI) were calculated for smoking (considering different definitions) for those with and without diabetes. Potential confounding factors including age, body mass index, estimated Glomerular Filtration Rate, hypertension, hypercholesterolemia and educational level were entered in the multivariate analysis. RESULTS In men with diabetes, the HR (95% CI) of comparing current and non-smokers was 1.25 (0.74-2.12) for incident CHD, 1.52 (0.96-2.40) for CVD and 2.10 (1.27-3.47) for mortality events; the corresponding values for men without diabetes were 1.65 (1.24-2.20), 1.70 (1.30-2.22) and 1.72 (1.14-2.58), respectively (all P values for interactions > 0.46). After pooling past smokers with current smokers, among diabetic individuals there was no significant risk for CVD [1.29 (0.89-1.86)] or mortality events [1.25 (0.81-1.92)]; however, among non-diabetic individuals the HRs of current/past smokers reached significant levels for CVD [1.53 (1.23-1.91)] but not for mortality outcomes (all P values for interactions > 0.51). CONCLUSIONS The strength of the associations between smoking habits and incident CVD/CHD and mortality events from all causes did not differ significantly among diabetic and non-diabetic participants. Therefore, a comprehensive community-based smoking prevention program is important, given the increasing trend of smoking among the Iranian population regardless of diabetes status.

Abstract
Patients with type2 diabetes mellitus have a high to very high cardiovascular risk, and often have other associated risk factors, such as hypertension, obesity and dyslipidaemia. Cardiovascular disease is the leading cause of morbidity and mortality in this population. An integrated control of all risk factors in patients with diabetes is essential for minimising the risk of macrovascular complications. Given the benefits of the multifactorial intervention strategies for cardiovascular prevention in diabetic patients, a review is presented on the therapeutic goals established for each risk factor in diabetes and the benefits of their control.

Abstract
Reports from recent studies suggest that diabetes confers a higher risk of cardiovascular disease in women compared to men. Larger studies, including meta-analyses, report that women with diabetes have a 44 % greater risk of incident coronary heart disease and a 27 % greater risk of incident stroke compared to men with diabetes. In this article, we summarize results from longitudinal studies that examine sex differences in risk factors for and rates of macrovascular complications from diabetes. We also discuss possible mechanisms for increased cardiovascular risk associated with diabetes in women compared to men, including the clustering of hypertension, obesity, and elevated triglycerides, the possible contribution of hormonal differences, and sex differences in the prescription of and adherence to pharmacologic treatment. In conclusion, diabetes is associated with a slightly higher risk of cardiovascular disease in women compared to men. Future studies should further explore the reasons underlying imperfect use of medications that lower cardiovascular risk in both women and men with diabetes.

Abstract
BACKGROUND Animal studies have shown antioxidant effects of Royal Jelly (RJ) and its effect on insulin resistance as the most common complication of Type 2 diabetes. This study was conducted to determine the effect of RJ intake on serum total antioxidant capacity, Malondialdehyde and insulin resistance in T2DM. METHODS In this randomized controlled trial, forty-six type 2 diabetic patients, aged 25-65 years, with BMI of 20-30 kg/m(2), and HbA1c of 6-8% were included. The patients were randomly assigned to receive 1000 mg of RJ supplement or placebo, 3 times daily for 8 weeks. HOMA-IR, anthropometric measurements, fasting blood glucose, serum insulin, total antioxidant capacity and malondialdehyde level were measured. RESULTS In comparison with placebo, HOMA-IR decreased (P=0.015) while serum total antioxidant capacity increased significantly in RJ group (P=0.016). No significant difference was detected for serum insulin and MDA in two groups. CONCLUSIONS RJ intake may have favorable effects on serum TAC and HOMA-IR in diabetic patients.

Resveratrol ameliorates high glucose-induced oxidative stress injury in human umbilical vein endothelial cells by activating AMPK. Life Sci 2015; 136:94-9. [PMID: 26188290 DOI: 10.1016/j.lfs.2015.07.008] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2015] [Revised: 06/22/2015] [Accepted: 07/07/2015] [Indexed: 12/13/2022]
Abstract
AIMS To investigate the effects of resveratrol on high glucose (HG)-induced vascular injury, and to establish the mechanism(s) underlying these effects. MAIN METHODS Human umbilical vein endothelial cells (HUVECs) were treated with glucose, and then incubated with resveratrol in the presence or absence of Compound C, an AMP-activated protein kinase (AMPK) inhibitor. Cell viability was determined using the Cell Counting Kit-8 (CCK-8) method. Reactive oxygen species, malondialdehyde, and superoxide dismutase were detected by flow cytometry, thiobarbituric acid reaction, and the nitroblue tetrazolium method, respectively. Protein levels of total and phosphorylated AMPKα and acetyl-CoA carboxylase were detected by immunoblotting. KEY FINDINGS Resveratrol significantly ameliorated HG-induced decreases in cell viability and superoxide dismutase levels and increases in reactive oxygen species and MDA levels. Moreover, resveratrol significantly reversed HG-induced dephosphorylation of AMPKα and acetyl-CoA carboxylase. However, treatment with Compound C curtailed the beneficial effects of resveratrol on HG-treated HUVECs. SIGNIFICANCE Resveratrol ameliorates HG-induced injury in HUVECs by activation of AMPKα, leading to increased cellular reductive reactions and decreased oxidative stress. These results provide further evidence for resveratrol-mediated activation of AMPKα.

[PMID: 26053222 PMCID: PMC4459959 DOI: 10.1371/journal.pone.0128627] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2015] [Accepted: 04/29/2015] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Whether diabetic patients without a history of coronary heart disease (CHD) have the same risk of CHD events as non-diabetic patients with a history of CHD remains controversial. This study aimed to determine whether type 2 diabetes mellitus (T2DM) is a coronary heart disease (CHD) equivalent in the need for coronary revascularization procedures (RVs) in the Korean population. METHODOLOGY/PRINCIPAL FINDINGS We followed 2,168,698 subjects who had oral anti-diabetic drugs (OADs)-taking T2DM in 2008 and/or CHD in 2007-2008 (i.e., recent CHD). We used systematic datasets from the nationwide claims database of the Health Insurance Review and Assessment service of Korea, which is representative of the whole population of Korea, from January 2007 to December 2012. The primary study endpoint was the development of need for RVs (i.e., incident CHD) after January 2009 among three groups based on their status of T2DM and recent CHD, i.e., T2DM only, recent CHD only, and both T2DM and recent CHD. After adjustment for age and sex, patients with recent CHD only had 2.14 times the risk of incident CHD (95% CI, 2.11-2.18, P<0.001) compared with patients with T2DM only. Patients with both T2DM and recent CHD demonstrated approximately 2-fold increased risk of incident CHD compared with subjects with recent CHD only (95% CI, 1.75-1.82), while 4-fold increased risk compared with subjects with T2DM only (95% CI, 3.71-3.87). The risk of incident CHD also differed according to sex and age. CONCLUSIONS/SIGNIFICANCE This analysis of data from the nationwide claims database revealed that T2DM did not have a recent CHD equivalent risk in the Korean population. These results suggest that an appropriate strategy for the CHD risk stratification in diabetic patients should be adopted to manage this population.

Abstract
AIMS/HYPOTHESIS To investigate secular trends in cardiovascular disease (CVD) risk factors during a decade of follow-up in a Middle Eastern cohort, and to compare observed trends between diabetic and non-diabetic populations. METHODS In a population of 6181 participants (2622 males and 3559 females), diabetes status and CVD risk factors were evaluated in 4 study phases from 1999-2011. 1045 subjects had type 2 diabetes mellitus at baseline and 5136 participants were diabetes-free. To examine the trends of CVD risk factors, generalized estimation equation models were constructed. The interaction between the diabetes status and each phase of the study was checked in a separate model. RESULTS During the follow-up period diabetic females significantly gained better control of their blood pressure, serum low density lipoprotein cholesterol and general and central obesity measures compared to non-diabetic counterparts, although 60% of them had high BP and 64% had high serum LDL-C levels till the end of the study. Diabetic males however, experienced significantly better control on their serum LDL-C and general and central obesity measures compared to their non-diabetic controls; but 24% of them were still smoker, 63% had high BP and 60% had high serum LDL-C levels at the end of the follow-up (all Ps interaction <0.05). Use of lipid-lowering and antihypertensive medications increased consistently in both diabetic and non-diabetic populations. CONCLUSIONS/INTERPRETATION Although CVD risk factors have been controlled to some extent among diabetic population in Iran, still high numbers of people with diabetes have uncontrolled CVD risk factors that prompt more attention.

Abstract
Context: Gender differences in the risk of developing non-communicable diseases (NCD) are a matter of debate. The susceptibility of a woman to NCD should be evaluated taking into consideration the social factors that limit the physical activity among women. It will be interesting to note what will happen if women are allowed to take part in physical exercise to the extent of men. Aims: To find out the gender difference in the pattern of the clinical and biochemical indices related to NCD in young adults with comparable daily physical activity. Settings and Design: This is an institution-based cross-sectional study and the setting was Lekshmibhai National College for Physical Education (LNCPE), Thiruvananthapuram, Kerala, India. Materials and Methods: The study participants were students who were regularly involved in more than three hours of physical exercise daily at least for the previous one year. The information on socio-demography, anthropometry, and blood pressure was recorded. Blood samples were taken for laboratory examination. Results: Out of 150 students registered, 126 (84%) in the age group of 17 to 25 years who fulfilled the eligibility criteria were studied. Fifty-five (43.7%) of them were women. Systolic blood pressure, fasting blood sugar, and low-density lipoprotein were found significantly lower in women. No significant difference was noted in the case of diastolic blood pressure and total cholesterol. Conclusion: Gender differences exist for NCD risk factors among young adults with comparable physical activity and physical exertion seems to be more protective for females.

Abstract
This article reviews the relationship between dyslipidemia, chronic kidney disease, and cardiovascular diseases in patients with diabetes. Diabetes mellitus is associated with complications in the cardiovascular and renal system, and is increasing in prevalence worldwide. Modification of the multifactorial risk factors, in particular dyslipidemia, has been suggested to reduce the rates of diabetes-related complications. Dyslipidemia in diabetes is a condition that includes hypertriglyceridemia, low high-density lipoprotein levels, and increased small and dense low-density lipoprotein particles. This condition is associated with higher cardiovascular risk and mortality in diabetic patients. Current treatment guidelines focus on lowering the low-density lipoprotein cholesterol level; multiple trials have confirmed the cardiovascular benefits of treatment with statins. Chronic kidney disease also contributes to dyslipidemia, and dyslipidemia in turn is related to the occurrence and progression of diabetic nephropathy. Different patterns of dyslipidemia are associated with different stages of diabetic nephropathy. Some trials have shown that treatment with statins not only decreased the risk of cardiovascular events, but also delayed the progression of diabetic nephropathy. However, studies using statins as the sole treatment of hyperlipidemia in patients on dialysis have not shown benefits with respect to cardiovascular risk. Diabetic patients with nephropathy have a higher risk of cardiovascular events than those without nephropathy. The degree of albuminuria and the reduction in estimated glomerular filtration rate are also correlated with the risk of cardiovascular events. Treatment with angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers to reduce albuminuria in diabetic patients has been shown to decrease the risk of cardiovascular morbidity and mortality.

Abstract
OBJECTIVE To evaluate the risk of cardiovascular events in diabetes defined by isolated post-challenge hyperglycaemia (IPH). METHODS We followed 3794 subjects aged ≥40 years without known history of diabetes or cardiovascular disease (CVD) at baseline for CVD events. Participants were categorized as subjects without diabetes [fasting plasma glucose (FPG) < 126 mg/dL and 2-h post-challenge plasma glucose (2-hPG) < 200 mg/dL], IPH (FPG < 126 mg/dL and 2-h PG ≥ 200 mg/dL) and fasting hyperglycaemia (fasting blood glucose (FBS) ≥ 126 mg/dL). Hazard ratios (HRs) were calculated with the use of Cox proportional-hazards regression models to evaluate the risk of CVD events. RESULTS At baseline, of 486 subjects with newly diagnosed diabetes, 190 (39%) had IPH. Over the next 8 years, age and sex-adjusted HR for incident CVD was 1.77 (95% confidence interval (CI): 1.19-2.64; p = 0.005) in subjects with IPH compared with subjects without diabetes. After further adjustment for potential confounders, the HR for CVD was not significant [1.32 (95% CI: 0.88-1.99; p = 0.2)]. CONCLUSIONS IPH in middle-aged adults adds nothing for identifying CVD risks when other risk factors are taken into account. Associated metabolic risk factors seem to be more important than hyperglycaemia per se.

Abstract
Type 2 diabetes increases the risk of cardiovascular disease (CVD) from two- to four-fold. In our large Finnish population-based study published in 1998 subjects with medication for type 2 diabetes had as high a risk of fatal and nonfatal myocardial infarction (MI) during the 7- year follow-up as non-diabetic subjects with a prior MI, suggesting that type 2 diabetes is a CVD equivalent. In another large study, including all 3.3 million residents of Denmark, subjects requiring glucose-lowering therapy exhibited a CVD risk similar to that of non-diabetic subjects with a prior MI. Subsequent studies have not systematically replicated aforementioned results. Some studies have supported the concept that type 2 diabetes is a CVD equivalent only in some subgroups, and many studies have reported negative findings. This is likely to be due to many differences across the studies published, for example ethnicity, gender, age and other demographic factors of the populations involved, study design, validation of diabetes status and CVD events, statistical analyses (adjustments for confounding factors), duration of diabetes, and treatment of hyperglycemia among diabetic participants. Varying results reflect the fact that not all diabetic patients are at a similar risk for CVD. Therefore, CVD risk assessment and the tailoring of preventive measures should be done individually, taking into consideration each patient's long-term risk of developing cardiovascular events.

Abstract
Aims. To provide a yardstick for physicians/patients to efficiently communicate/measure incident diabetes risk. Methods. We included data on 5,960 (3,438 women) diabetes-free adults, aged ≥20 years at baseline who either developed diabetes during two consecutive examinations or completed the followup. Age, systolic blood pressure, family history of diabetes, waist-to-height ratio (WHtR), triglyceride-to-high-density lipoprotein cholesterol ratio (TG/HDLD-C), and fasting plasma glucose (FPG) were introduced into an accelerated failure time regression model. Results. Annual diabetes incidence rate was 0.85/1000-person (95% CIs 0.77–0.94). Point-score-system incorporated age (1 point for >65 years), family history of diabetes (4 points), systolic blood pressure (−1 to 3 points), WHtR (−4 to 6 points), TG/HDL-C (1 point for ≥1.5), and FPG (0 to 27 points). Harrell's C statistic = 0.830 (95% CIs 0.808–0.852) and Hosmer-Lemeshow χ2 = 9.7 (P for lack of fitness = 0.462) indicated good discrimination and calibration. We defined beta-cell age as chronological age of a person with the same predicted risk but all risk factors at the normal levels (i.e., WHtR 0.50, no family history of diabetes, Ln (TG/HDL-C) = 0.531, and FPG = 4.9 (mmol·L−1)). Conclusion. Hereby, we have made it also possible to estimate wide ranges of “beta-cell age” for most chronological ages to assist clinician with risk communication.

Abstract
The utility of a risk function in clinical practice is an important concept that has received insufficient attention. The authors evaluated the clinical usefulness of the Framingham risk function (FRF) for cardiovascular disease in a Middle Eastern population (2,640 men and 3,584 women aged 30-74 years) free of cardiovascular disease at baseline in 1999. They calculated the net benefit fraction for treatment of subjects with an estimated 10-year risk of ≥10% and also ≥20%, where the net benefit fraction is a weighted sum of true-positive and false-positive rates divided by incidence, as estimated by Kaplan-Meier analysis. The authors drew a decision curve by plotting the net benefit fraction against a wide range of risk thresholds for treatment. The cumulative incidence of cardiovascular disease was 7.6% and 12.3% in women and men, respectively. The FRF had a C index of 0.832 in women and 0.785 in men with a reasonable calibration. On the basis of the net benefit fraction, about 50% of the incidence in men and women could be appropriately treated by using the 10% threshold; however, the FRF was not useful at the 20% threshold, especially in women. In both genders, usefulness of the FRF was as good as the function derived directly from Tehrani data with the same variables; however, it could be useful in low thresholds for treatment.

Abstract
BACKGROUND AND OBJECTIVE The aim of this cross-sectional study was to compare the prevalence of target organ damage (TOD) and established cardiovascular disease (CVD) in a cohort of nondiabetic hypertensive patients with 3 or more cardiovascular risk factors (CVRF) against a group of hypertensives with type 2 diabetes. PATIENTS AND METHOD We included 4,725 hypertensive patients, 62% male, mean age 64 (SD 12) years, with type 2 diabetes mellitus, independently of the number of associated CVRF (N=2,608), or non-diabetics, in which case we required the presence of 3 CVRF (N=2,117). The prevalence of established CVD (clinical interview) and TOD (left ventricular hypertrophy by electrocardiogram, microalbuminuria and estimated glomerular filtration rate) were estimated. RESULTS Hypertensive patients with type 2 diabetes had an older age and more marked obesity. Furthermore, these patients showed a higher prevalence of micro- and macroalbuminuria, renal failure, left ventricular hypertrophy, atherosclerotic plaques in carotid arteries and CVD compared with nondiabetic hypertensive patients with 3 or more CVRF. Multivariate analysis showed that the risk of TOD or established CVD were associated independently with the presence of diabetes. CONCLUSION Hypertensive patients with type 2 diabetes have a higher prevalence of LOD and CVD compared to nondiabetic hypertensive patients with 3 or more CVRF. Although both situations are included in the high cardiovascular risk stratum, it would be expected an increased incidence of cardiovascular complications in hypertensive diabetic patients.

Abstract
BACKGROUND Type 2 diabetic patients are faced with a higher risk of dyslipidemia and cardiovascular disorders. This study was undertaken to assess the effect of consumption of 1 cup cranberry juice by type 2 diabetic patients on serum paraoxonase-1 (PON-1) activity, apoA-1, apoB, glucose, and Lp(a). METHODS In a double-blind randomized clinical trial, 58 type 2 diabetic male patients were randomly divided to receive 1 cup cranberry juice (CJ) or placebo drink daily for 12 weeks. Fasting blood were obtained at beginning and at the end of study (12(th) week). Serum glucose and PON-1 activity were measured by enzymatic and colorimetric methods, respectively. ApoB, apoA-I, and Lp(a) were determined immunoturbidimetrically. The data were analyzed by SPSS version 16. RESULTS There were significant decrease in serum glucose and apoB (P>0.05 and P>0.01, respectively) and significant increase in serum apoA-1 and PON-1 activity (P>0.05 and P<0.01, respectively) at the end of study in CJ group compared with control group. In CJ group at the end of study, there were significant decrease in serum glucose and apoB (P<0.01 and P<0.01, respectively) and significant increase in serum apo A-1 and PON-1 activity (P<0.01 and P<0.01, respectively) compared with initial values. In CJ group, there was no significant change in Lp(a) at the end of study compared with initial values and also compared with control group. CONCLUSION 1 cup CJ for 12 weeks is effective in reducing serum glucose and apoB and increasing apoA-1 and PON-1 activity, so may have favorite effects on reducing CVD risk factors in type 2 diabetic male patients.

Abstract
OBJECTIVE Diabetes mellitus type 2 (DM2) is a risk factor for coronary heart disease (CHD). While there is a clear correlation of fasting blood glucose (FBG) and 2 h post-challenge blood glucose values (2h-BG) with microvascular complications, the risk for CHD conferred by glucose dysregulation antecedent to DM2 is less clear. Therefore, we investigated associations of FBG and 2h-BG values with the prevalence of CHD assessed by coronary angiography as the most sensitive diagnostic tool. RESEARCH DESIGN AND METHODS Coronary angiography was performed in 1394 patients without known DM. Capillary blood glucose was analyzed before and 2 h after an oral glucose tolerance test. Associations between FBG as well as 2h-BG levels and the risk for CHD were assessed by logistic regression analysis. RESULTS 1064 (75%) of patients were diagnosed with CHD. 204 (15%) were diagnosed with so far unknown DM2, 274 (20%) with isolated impaired fasting glucose (IFG), 188 (13%) with isolated impaired glucose tolerance (IGT) and 282 (20%) with both, IGT and IFG. We found a continuous increase in the risk for CHD with fasting and post-challenge blood glucose values even in the subdiabetic range. This correlation did however not suggest clear cut-off values. The increase in risk for CHD reached statistical significance at FBG levels of > 120 mg/dl (Odds Ratio of 2.7 [1.3-5.6] and 2h-BG levels > 140 mg/dl (141-160 mg/dl OR 1.8 [1.1-2.9], which was however lost after adjusting for age, sex and BMI. CONCLUSIONS In our study population we found a continuous increased risk for CHD at fasting and 2h-BG levels in the sub-diabetic glucose range, but no clear cut-off values for cardiovascular risk.

Comparing the outcomes of open surgical procedure and percutaneously peritoneal dialysis catheter (PDC) insertion using laparoscopic needle: A two month follow-up study. JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2011; 16:463-8. [PMID: 22091260 PMCID: PMC3214349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2010] [Accepted: 03/05/2011] [Indexed: 11/19/2022]
Abstract
BACKGROUND This study was performed to compare the outcomes of open surgical procedure and percutaneously peritoneal dialysis catheter (PDC) insertion using laparoscopic needle. METHODS This randomized clinical trial study was conducted in the Nephrology Department in Noor Hospital, Isfahan, Iran between 2009 and 2010. 64 uremic patients were randomized into two study groups using random allocation software. Thirty four catheters were inserted percutaneously (P group) and 30 catheters were placed surgically (S group). Collected information included demographic data, body mass index, and cause of renal disease, duration of operation and length of hospitalization. Outcomes were considered as mechanical and infectious complications. RESULTS There were no significant differences in age, gender, the mean of body mass index, having history of hemodialysis, diabetes mellitus, hypertension, ischemic heart disease, and length of hospitalization. Hemopenitoneom was more frequent in S group than P group (13.3% versus 3.2%; p < 0.0001). There was no significant difference between two groups in early peritonitis, early leakage, hernia, hollow viscous perforation, catheter obstruction, and malpositioning and the time of peritoneal dialysis onset. Outflow failure and the exit site infection were more frequent in S group than P group (p < 0.0001). Mean of the operative time was longer in S group than P group (27.70 ± 2.79 minutes versus 10.48 ± 1.91 minutes, p < 0.001). CONCLUSIONS Percutaneous catheter insertion has fewer rate of complications and is less time consuming in comparison with surgical method.
