Int J Mol Sci 2024; 25:5431. [PMID: 38791468 PMCID: PMC11122116 DOI: 10.3390/ijms25105431] [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: 03/26/2024] [Revised: 04/24/2024] [Accepted: 04/29/2024] [Indexed: 05/26/2024] Open
Abstract
Maternal type 2 diabetes mellitus (T2DM) has been shown to result in foetal programming of the hypothalamic-pituitary-adrenal (HPA) axis, leading to adverse foetal outcomes. T2DM is preceded by prediabetes and shares similar pathophysiological complications. However, no studies have investigated the effects of maternal prediabetes on foetal HPA axis function and postnatal offspring development. Hence, this study investigated the effects of pregestational prediabetes on maternal HPA axis function and postnatal offspring development. Pre-diabetic (PD) and non-pre-diabetic (NPD) female Sprague Dawley rats were mated with non-prediabetic males. After gestation, male pups born from the PD and NPD groups were collected. Markers of HPA axis function, adrenocorticotropin hormone (ACTH) and corticosterone, were measured in all dams and pups. Glucose tolerance, insulin and gene expressions of mineralocorticoid (MR) and glucocorticoid (GR) receptors were further measured in all pups at birth and their developmental milestones. The results demonstrated increased basal concentrations of ACTH and corticosterone in the dams from the PD group by comparison to NPD. Furthermore, the results show an increase basal ACTH and corticosterone concentrations, disturbed MR and GR gene expression, glucose intolerance and insulin resistance assessed via the Homeostasis Model Assessment (HOMA) indices in the pups born from the PD group compared to NPD group at all developmental milestones. These observations reveal that pregestational prediabetes is associated with maternal dysregulation of the HPA axis, impacting offspring HPA axis development along with impaired glucose handling.

[PMID: 37867630 PMCID: PMC10590134 DOI: 10.2147/dmso.s433112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 10/04/2023] [Indexed: 10/24/2023] Open
Abstract
Purpose The incidence of prediabetes mellitus (pre-DM) is increasing among young individuals. Whether pre-DM can predict adverse cardiovascular events in acute coronary syndrome (ACS) patients remains controversial. This study aimed to investigate the impact of pre-DM on the long-term clinical outcomes of patients aged≤ 45 years with new-onset ACS. Patients and methods A total of 1113 patients with new-onset ACS (aged≤ 45 years) who underwent percutaneous coronary intervention (PCI) were enrolled in this study. Patients were divided into three groups according to their glycemic status or history: normal glucose metabolism (NGM), prediabetes (pre-DM), and diabetes mellitus (DM). The primary endpoint was defined as a composite of major adverse cardiovascular events (MACE) including all-cause death, myocardial infarction (MI), stroke, or unplanned repeat revascularization. Multivariate Cox regression analysis was performed to explore the association between abnormal glycemic status and MACE. Results The prevalence of NGM, pre-DM, and DM were 45.9% (n=511), 27.0% (n=301), and 27.0% (n=301), respectively. During a median follow-up of 65 months, MACE occurred in 23.5% (n=120) of NGM, 29.2% (n=88) of pre-DM, and 34.6% (n=104) of DM (P=0.003). After multivariate adjustment, both pre-DM and DM significantly increased the risk of MACE compared with the NGM group (pre-DM: HR1.38, CI95% 1.05-1.83, P=0.023; DM: HR1.65, CI95% 1.27-2.16, P<0.001). Moreover, pre-DM had a similar impact on MACE as DM in young patients with ACS (P=0.162). Conclusion Pre-DM was common among patients aged≤ 45 years with new-onset ACS. Pre-DM was associated with an increased risk of future MACE compared to NGM.

Association of LDL:HDL ratio with prediabetes risk: a longitudinal observational study based on Chinese adults. Lipids Health Dis 2022; 21:44. [PMID: 35570291 PMCID: PMC9107720 DOI: 10.1186/s12944-022-01655-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 05/06/2022] [Indexed: 12/14/2022] Open
Abstract
Background Low-density lipoprotein:high-density lipoprotein cholesterol ratio (LDL:HDL ratio) has a good performance in identifying diabetes mellitus (DM) and insulin resistance. However, it is not yet clear whether the LDL:HDL ratio is associated with a high-risk state of prediabetes. Methods This cohort study retrospectively analyzed the data of 100,309 Chinese adults with normoglycemia at baseline. The outcome event of interest was new-onset prediabetes. Using multivariate Cox regression and smoothing splines to assess the association of LDL:HDL ratio with prediabetes. Results During an average observation period of 37.4 months, 12,352 (12.31%) subjects were newly diagnosed with prediabetes. After adequate adjustment for important risk factors, the LDL:HDL ratio was positively correlated with the prediabetes risk, and the sensitivity analysis further suggested the robustness of the results. Additionally, in stratified analysis, we discovered significant interactions between LDL:HDL ratio and family history of DM, sex, body mass index and age (all P-interaction < 0.05); among them, the LDL:HDL ratio-related prediabetes risk decreased with the growth of body mass index and age, and increased significantly in women and people with a family history of DM. Conclusions The increased LDL:HDL ratio in the Chinese population indicates an increased risk of developing prediabetes, especially in women, those with a family history of DM, younger adults, and non-obese individuals.

Front Endocrinol (Lausanne) 2022; 13:965545. [PMID: 36387884 PMCID: PMC9648615 DOI: 10.3389/fendo.2022.965545] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 10/14/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE There is still limited evidence regarding the relationship between the estimated glomerular filtration rate (eGFR) and pre-diabetes. For that reason, our research aims to survey the association of eGFR with pre-diabetes. METHODS This study was a retrospective cohort study, which consecutively and non-selectively collected a total of 173301 participants from Rich Healthcare Group in China from January 2010 to 2016. We then used the Cox proportional-hazards regression model to explore the relationship between baseline eGFR and pre-diabetes risk. Using a Cox proportional hazards regression with cubic spline function and smooth curve fitting (cubical spline smoothing), we were able to determine the non-linear relationship between eGFR and pre-diabetes. Additionally, we also conducted a series of sensitivity analyses and subgroup analyses. The DATADRYAD website was updated with data. RESULTS The mean age of the included individuals was 40.95 ± 11.94 years old, and 92318 (53.27%) were male. The mean baseline eGFR was 111.40 ± 14.77 ml/min per 1.73 m2. During a median follow-up time of 3.0 years, 18333 (10.58%) people experienced pre-diabetes. As a result of adjusting for covariates, eGFR had a negative association with incident pre-diabetes (HR=0.993, 95%CI: 0.992-0.995). There was also a U-shaped curve relationship between eGFR and pre-diabetes, and the inflection point of eGFR was 129.793 ml/min per 1.73 m2. HRs on the left and right sides of the inflection point were respectively 0.993 (0.991-0.994) and 1.023 (1.010- 1.037). Our results were robust in the sensitivity analysis. Subgroup analyses indicated that eGFR was strongly associated with the risk of pre-diabetes among participants who were younger than 30 years and 40-70 years, as well as among those who had never smoked. In contrast, the association of eGFR with the risk of pre-diabetes was attenuated among participants who were 30-40 years of age and 70 years of age or older, and among those who currently smoked. CONCLUSION This study demonstrates a negative and U-shaped curve association between eGFR and the risk of pre-diabetes among the general Chinese population. Either reduced renal function or glomerular hyperperfusion status may be associated with an increased risk of prediabetes.

Abstract
The skeletal muscle is the largest organ in the body, by mass. It is also the regulator of glucose homeostasis, responsible for 80% of postprandial glucose uptake from the circulation. Skeletal muscle is essential for metabolism, both for its role in glucose uptake and its importance in exercise and metabolic disease. In this article, we give an overview of the importance of skeletal muscle in metabolism, describing its role in glucose uptake and the diseases that are associated with skeletal muscle metabolic dysregulation. We focus on the role of skeletal muscle in peripheral insulin resistance and the potential for skeletal muscle-targeted therapeutics to combat insulin resistance and diabetes, as well as other metabolic diseases like aging and obesity. In particular, we outline the possibilities and pitfalls of the quest for exercise mimetics, which are intended to target the molecular mechanisms underlying the beneficial effects of exercise on metabolic disease. We also provide a description of the molecular mechanisms that regulate skeletal muscle glucose uptake, including a focus on the SNARE proteins, which are essential regulators of glucose transport into the skeletal muscle. © 2020 American Physiological Society.

Abstract
Objective: Early identification and management of prediabetes is critical to prevent progression to diabetes. We aimed to assess whether prediabetes is appropriately recognized and managed among patients with impaired fasting glucose (IFG). Methods: We carried out an observational study of Olmsted County residents evaluated at the Mayo Clinic between 1999-2017. We randomly selected 108 subjects with biochemical criteria of IFG and 105 normoglycemic subjects. We reviewed their health records at baseline (1999-2004) and during follow up (2005-2017) collecting demographic and clinical data including vitals, diagnoses, laboratory, and medications associated with cardiovascular comorbidities. The main outcome was documentation of any recognition of prediabetes and management recommendations (lifestyle changes and/or medications). Results: At baseline (1999-2004), 26.85% (29/108) of subjects with IFG were recognized as having prediabetes, and of these 75.86% (22/29) received management recommendations with 6.9% (2/29) getting metformin. During follow-up (2005-2017), 26.67% (28/105) of initial cohort of normoglycemic subjects developed incident IFG and of these, 85.71% (24/28) were recognized as having prediabetes, and 58.33% (14/24) received management recommendations. During the entire study period, 62.50% (85/136) were recognized as having prediabetes of which 75.29% (64/85) had documented management recommendations. High body mass index (BMI) (≥35) was associated with increased recognition (odds ratio [OR] 3.66; confidence interval [CI] 1.065, 12.500; P = .0395), and normal BMI (<25) was associated with a lack of recognition (OR 0.146; CI 0.189, 0.966; P = .0413). Conclusion: Despite evidence supporting the efficacy of lifestyle changes and medications in managing prediabetes, this condition is not fully recognized in routine clinical practice. Increased awareness of diagnostic criteria and appropriate management are essential to enhance diabetes prevention.

Abstract
Communication of risk is not solely the transfer of information; it is an interaction and exchange of ideas between concerned individuals. Health care provider communication about type 2 diabetes risk status may influence individual participation in behaviours that prevent or delay the disease, which is concerning from a public health perspective. The term prediabetes is used to convey risk status and little is known about how health care providers view or use the term. In this article, we describe health care provider use and perceptions of the term prediabetes drawing on data from a survey conducted between August and November 2011 of 15 health care providers practicing in Southeast Wyoming and Northern Colorado USA. We used a grounded theory research design to guide data collection and analysis and in the interviews invited providers to describe their use and perception of the term prediabetes. We found that providers use of the term 'prediabetes' depended on their view of the term's meaning (such as, whether patients were likely to understand or be confused by it) and impact (in terms of motivating patients to mitigate risk). We found there were differences in providers' perceptions of the negative and positive associations of the term and this influenced whether or not they used it. These findings are not surprising given the lack of consensus over definitions and diagnosis criteria for prediabetes. Given this this lack of agreement, there are difficulties about the use of the term prediabetes and its use should take place within effective risk communication. Health care providers must consider essential aspects of risk communication in order to enable individuals at risk of type 2 diabetes to mitigate the risk and by doing so reduce incidence and prevalence rates of the disease.

Abstract
AIMS To examine the abilities of HbA1c and fasting plasma glucose (FPG) criteria predicting 5-year progression rate to diabetes in Korean adults with prediabetes. METHODS Participants included 17,971 Koreans (aged 20-79years) who underwent routine medical check-ups at a mean interval of 5.2years (3.1-6.7years). Prediabetes was defined as FPG 5.6-6.9mmol/l or HbA1c 5.7-6.4% (39-46mmol/mol). Incident diabetes was defined as FPG⩾7.0mmol/l, HbA1c⩾6.5% (48mmol/mol), or initiation of antidiabetic medications. RESULTS At baseline, the prevalence of prediabetes was 30.6% (n=5495) by FPG and 20.4% (n=3664) by HbA1c criteria. The 5-year progression rate to diabetes was significantly higher in prediabetes identified by HbA1c than by FPG tests (14.7% vs. 10.4%, P<0.001). Of individuals diagnosed with prediabetes by only one test, those by HbA1c alone had a higher risk of progression to diabetes than those diagnosed by FPG alone (6.0% vs. 3.9%, P<0.001). Receiver operating characteristic curve analysis showed that area under the curve was greater for HbA1c (0.855, 95% CI 0.840-0.870) than for FPG (0.830, 0.813-0.846) (P=0.016). After adjustment for conventional risk factors, the odds ratio (OR) of developing diabetes was higher in participants with prediabetes identified by HbA1c (OR 9.91, 8.24-11.9) than by FPG (OR 7.29, 5.97-8.89) (P=0.026). CONCLUSIONS Although fewer individuals with prediabetes were identified by HbA1c than by FPG criteria, the ability to predict progression to diabetes was stronger for HbA1c than for FPG in Koreans.

Abstract
BACKGROUND Abnormalities in the glucose metabolism cause nervous and organic damage and are a cardiovascular risk factor. They could be a main cause for the increased morbidity and mortality rates found in patients with bipolar disorders. The exact prevalence of diabetes and pre-diabetic abnormalities, however, is not clear. METHODS 85 euthymic outpatients with bipolar disorders from two university hospitals in Germany underwent an oral glucose tolerance test, laboratory screening and clinical measurements. Socio-demographic data, medication, severity of illness, global functioning and life quality were assessed. RESULTS Diabetes mellitus was found in 7% of the patients, pre-diabetic abnormalities in 27%. The group of patients with abnormalities in the glucose metabolism had significantly lower quality of life and global functioning. Higher BMI, leptin, triglycerides and CRP levels significantly increased the likelihood for pre-diabetes/diabetes. LIMITATIONS The low sample size did only allow limited assessment of impact of medication on the results. No healthy controls were assessed. CONCLUSIONS One-third of the patients with bipolar disorders showed abnormalities in the glucose metabolism and this was associated with impaired global functioning and lower quality of life. Early detection and intervention strategies fitting the needs of patient with bipolar disorder are needed to improve both physical and mental health.

Abstract
OBJECTIVE Discordance between HbA1c and OGTT in screening pre-diabetes may occur because of lack of laboratory standardization, distinct underlying pathophysiological processes or different ethnicity. We evaluated HbA1c efficacy for screening OGTT-defined IFG and IGT conditions in a large Caucasian population using the newly revised IFCC protocol. RESEARCH DESIGN AND METHODS A total of 501 consecutive subjects were screened for pre-diabetic conditions with OGTT with 75 g of glucose. Testing for HbA1c, lipid profile and fasting insulin levels was also performed. For detecting differences between continuous variables, ANOVA followed by Tukey's honestly significant difference (HSD) post hoc test was used. Logistic regression and ROC curve analysis were also performed for assessing HbA1c screening efficacy. RESULTS ROC curve analysis showed that optimal HbA1c cut-off for detecting IFG was 5.6 % (sensitivity of 78 % and specificity of 63 %), while for IGT, the optimal cut-off was 5.9 % (sensitivity of 46 % and specificity of 84 %), with AUCs < 0.8. Screening with HbA1c identified 53.4 % of the 193 patients with IFG and/or IGT diagnosed at OGTT. As regards surrogate markers of insulin resistance, we observed a trend towards higher values of HOMA-IR and lower QUICKI values in subjects with IFG than in those with IGT. Patients with pre-diabetes at both tests had similar values of HOMA and QUICKI, compared with those with altered OGTT only. CONCLUSIONS IFCC-aligned HbA1c assay proved scarcely effective in detecting IFG and/or IGT in a large Caucasian population, identifying only half of the patients with abnormal OGTT. Moreover, adding HbA1c screening to OGTT may be of little benefit in identifying subjects with a worse metabolic profile.

Abstract
AIM To evaluate the association between health-related quality of life and glucose metabolism status in a study population in Qazvin, Iran. METHODS This cross-sectional study was conducted in 1044 people (aged 20-78 years old) between September 2010 and April 2011 in Qazvin, Iran. An oral glucose tolerance test was performed for each participant who had never been diagnosed with diabetes. Participants were characterized as having normal glucose metabolism, pre-diabetes or diabetes according to American Diabetes Association criteria. The short-form 36 questionnaire was used to measure quality of life. Data were analysed using a chi-squared test, anova and ancova. RESULTS A total of 530 (51.7%) of the participants were women, and 24.1 and 11.6% of the participants were categorized as having prediabetes and diabetes mellitus, respectively. Except for the role emotional domain, there was a gradual decrease in the mean scores of every domain of the short-form 36 scale across the three study groups. The mean scores in the physical domains were significantly different among the participants with normal glucose metabolism and those with diabetes. After adding age as covariate, there were no significant differences between the categories in any of the domains. CONCLUSION There is no association between quality of life domains and glucose metabolism status in Iranian subjects. More longitudinal studies are necessary to investigate the natural history of pre-diabetes, diabetes and quality of life.

[PMID: 24800183 PMCID: PMC4007341 DOI: 10.4103/2277-9175.129364] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2012] [Accepted: 06/09/2012] [Indexed: 01/13/2023] Open
Abstract
Background: The global prevalence of diabetes mellitus is increasing rapidly. Measurement of glycated hemoglobin, predominantly HbA1c, is fundamental to the management of patients with diabetes. HbA1c is used to monitor long-term glycemic control, adjust therapy, assess the quality of diabetes care and predict the risk for the development of complications. While HbA1c is the standard method for long-term glycemic control in diabetic patients, there are different methods for measurement of HbA1c and all laboratories do not use the reference method (high-performance liquid chromatography [HPLC]). The objective of this study is comparison of three different methods with HPLC to find out which method has an acceptable concordance and correlation with the reference method. Materials and Methods: Fifty-eight diabetic patients were assessed in this study. The blood sample of each patient was checked with Diazyme (enzymatic assay), Nycocard (boronate-affinity binding) and Biosystem (micro column chromatography). The values of HbA1c of each method were compared with the Knauer-HPLC results. Results: The means of the differential values between each method and HPLC in the ANOVA test are as follows: M = 1.8, SD = 1.09 for Nycocard-HPLC; M = 1.5, SD = 1.08 for biosystem-HPLC; M = 1.3, SD = 1.2 for Diazyme-HPLC. Pearson's correlation coefficient between HPLC and Nycocard; 0.76, HPLC and Diazyme; 0.75 and between HPLC and Biosystem was 0.68. Linear regression parameters for each method with HPLC were also determined. Conclusion: Diazyme had a better performance and showed a greater concordance with HPLC among others, although it was not an ideal alternative for HPLC.

Abstract
PURPOSE This article reports the results of a community-based, culturally tailored diabetes prevention program for overweight Mexican American adults on weight loss, waist circumference, diet and physical activity self-efficacy, and diet behaviors. METHODS The intervention used content from the Diabetes Prevention Program but culturally tailored the delivery methods into a community-based program for Spanish-speaking adults of Mexican descent. The design was a randomized controlled trial (N = 58) comparing the effects of a 5-month educational intervention with an attention control group. The primary study outcome was weight loss. Secondary outcomes included change in waist circumference, body mass index, diet self-efficacy, and physical activity self-efficacy. RESULTS There were significant intervention effects for weight, waist circumference, body mass index, and diet self-efficacy, with the intervention group doing better than the control group. These effects did not change over time. CONCLUSIONS Findings support the conclusion that a community-based, culturally tailored intervention is effective in reducing diabetes risk factors in a 5-month program.

Abstract
UNLABELLED We aimed to explore the association of advanced oxidation and advanced glycation of proteins, and their interrelations with endothelial nitric oxide synthesis, oxidative stress, metabolic profile as well as other atherosclerotic risk markers in prediabetic and diabetic elderly subjects. Advanced glycation end products (AGEs), advanced oxidation protein products (AOPPs), low-density lipoprotein susceptibility to oxidation (oxLDL) and nitric oxide metabolic pathway products (NOx) were assessed in subjects with impaired fasting glucose (prediabetes, IFG; n=90), and type 2 diabetes mellitus (T2DM, n=95) versus control subjects (n=88). Higher levels of AOPPs, AGEs, oxLDL, NOx, atherosclerosis risk markers, and insulin resistance were pointed out in IFG and T2DM groups compared with control. Strong positive associations (p<0.01) of AGEs with fasting glucose and HbA1c were found in both hyperglycemic groups, whereas AOPPs were significantly correlated (p<0.01) only in T2DM. In T2DM, AGEs and AOPPs significantly (p<0.01) correlated with insulin resistance index HOMA-IR, oxLDL and small LDL particle size (TG/HDL-C), and positively with NOx. Direct associations of AGEs and AOPPs with TC/HDL-C and oxLDL/HDL-C, and AGEs-AOPPs interrelations (p<0.01) were identified in IFG and T2DM groups. AGEs and AOPPs in combination with oxLDL and NOx could be important biomarkers for evaluating the association between diabetes and atherosclerotic disorders in aging diabetic patients. BIOLOGICAL SIGNIFICANCE In the present study we have made an attempt to approach the biological and clinical significance of the oxidative and glycoxidative protein damage, in subjects with prediabetes and type-2 diabetes mellitus. AGEs and AOPPs in combination with oxLDL and NOx appear to be important biomarkers for evaluating the association between diabetes and atherosclerotic disorders in aging diabetic patients. More importantly, this cluster of biomarkers that links the short term, "real time" metabolic impairment parameters (NOx, serum glucose, HOMA-IR, serum lipid profile) and the "metabolic memory" markers resulting from the long-term hyperglycemia and hyperlipidemia-induced oxidative stress (HbA1c, AGEs, AOPPs and oxLDL), could be valuable in predicting not only vascular complications in T2DM, but also the onset of diabetes, hence enabling therapeutic interventions from the early stages of diabetes. This article is part of a Special Issue entitled: Posttranslational Protein modifications in biology and Medicine.

Abstract
AIM OF THE STUDY In the present work, the objective was to evaluate the influence of a dietary sodium restriction on cardiovascular morphology changes associated with insulin-resistance. ANIMALS AND PROTOCOL At 8 weeks of age, rats were fed for 12 weeks a 60%-fructose diet containing a regular sodium content (0.64%) or totally lacking in sodium chloride (<0.01%). A group of rats fed a wheat starch-based diet with regular sodium content served as control group. RESULTS Elevated HOMA index and plasma insulin confirm the presence of insulin-resistance in fructose-fed rats. Concomitantly, an increase in cardiac mass and in cardiac collagen (Sirius red staining) was detected without obvious change in arterial pressure or cardiac aldosterone synthase mRNA expression. In addition, cross-sectional area of the carotid artery was higher in fructose-fed rats. Production of superoxide anion, equated with dihydroethidium (DHE) staining, was enhanced in cardiac tissue of rats with insulin-resistance. Withdrawal of sodium from the fructose diet prevented all the cardiovascular effects of fructose consumption, including DHE staining. CONCLUSION These results are in favor of the participation of oxidative stress normalization in the beneficial influence of dietary sodium deprivation on cardiovascular remodeling in this model of insulin-resistance in rats.
