OBJECTIVE: We aimed to quantify the risk of future maternal T2DM in women with GDM based on the type and number of abnormal 75g-OGTT values and the diagnostic criteria used for the diagnosis of GDM. <p>RESEARCH DESIGN AND METHODS: We conducted a population-based retrospective cohort study of all nulliparous women with a live singleton birth who underwent testing for GDM using a 75g-OGTT in Ontario, Canada (2007-2017). We estimated the incidence rates (per 1000 person years), overall risk (expressed as adjusted hazard ratio [aHR]), and risk at 5-year post the index pregnancy of future maternal T2DM. Estimates were stratified by the type and number of abnormal OGTT values, as well as by the diagnostic criteria for GDM (Diabetes Canada vs. IADPSG criteria). </p> <p>RESULTS: A total of 55,361 women met the study criteria. The median duration of follow-up was 4.4 (IQR 2.8-6.3, maximum 10.3) years. Using women without GDM as reference (incidence rate 2.18 per 1000py), women with GDM were at an increased risk of future T2DM, with the risk being higher for the Diabetes Canada compared with the IADPSG criteria (incidence rate 18.74 [95%-CI 17.58-19.90] vs. 14.07 [95%-CI 13.24-14.91] per 1000py, respectively). The risk of future maternal T2DM increased with the number of abnormal OGTT values, and was highest for women with 3 abnormal values (incidence rate 49.93 per 1000py; aHR 24.57 [95%-CI 21.26-28.39]). The risk of future T2DM was also affected by the type of OGTT abnormality: women with an abnormal fasting value had the greatest risk while women with an abnormal 2-hour value had the lowest risk for future T2DM (aHR 14.09 [95%-CI 12.46-15.93) vs. 9.22 [95%-CI 8.19-10.37]), respectively). <a></a><a>Similar findings to those described above were observed when the risk of T2DM at a fixed time point of 5-years post the index pregnancy was considered as the outcome of interest</a>.</p> <p>CONCLUSION: In women with GDM, individualized information regarding the future risk of T2DM can be provided based on the type and number of abnormal OGTT values, as well as the diagnostic criteria used for the diagnosis of GDM. </p>

Background To compare current guidelines for diagnosis of gestational diabetes mellitus (GDM) and to identify the ones that are the most relevant for application among pregnant Bulgarian population. Methods A total of 800 pregnant women at high risk for GDM underwent 75 g oral glucose tolerance test between 24 and 28 weeks of gestation as antenatal screening. The results were interpreted and classified according to the guidelines of the International Association of Diabetes and Pregnancy Study Groups (IADPSG), American Diabetes Association (ADA), Australasian Diabetes in Pregnancy Society, Canadian Diabetes Association, European Association for the Study of Diabetes, New Zealand Society for the study of Diabetes and World Health Organization. Results The application of different diagnostic criteria resulted in prevalences of GDM between 10.8% and 31.6%. Using any two sets of criteria, women who were classified differently varied between 0.1% and 21.1% ( P < 0.001).The IADPSG criteria were the most inclusive criteria and resulted in the highest prevalence of GDM. There was a significant difference in the major metabolic parameters between GDM and control groups, regardless of which of the diagnostic criteria applied. GDM diagnosed according to all criteria resulted in increased proportion of delivery by caesarean section (CS). However, only ADA and IADPSG criteria identified both increased macrosomia (odds ratio, 2.36; 2.29) and CS rate. Conclusion The need for GDM screening is indisputable. In our view, the new IADPSG guidelines offer a unique opportunity for a unified national and global approach to GDM.

The aim of the study was to assess the postpartum risk for glucose intolerance since the introduction of the ‘International Association of Diabetes and Pregnancy Study Groups’ (IADPSG) criteria for gestational diabetes mellitus (GDM). Studies published since 2010 were included, which evaluated the risk for type 2 diabetes mellitus (T2DM), impaired glucose tolerance (IGT), and cardiovascular (CV) events in women with previous GDM compared to normal glucose tolerant women. We included forty-three studies, evaluating 4,923,571 pregnant women of which 5.8% (284,312) had a history of GDM. Five studies used IADPSG criteria (n = 6174 women, 1314 with GDM). The overall pooled relative risk (RR) for postpartum T2DM was 7.42 (95% CI: 5.99–9.19) and the RR for postpartum T2DM with IADPSG criteria was 6.45 (95% CI: 4.74–8.77) compared to the RR of 9.08 (95% CI: 6.96–11.85; p = 0.17) for postpartum T2DM based on other diagnostic criteria. The RR for postpartum IGT was 2.45 (95% CI: 1.92–3.13), independent of the criteria used. None of the available studies with IADPSG criteria evaluated the risk for CV events. Women with a history of GDM based on the IADPSG criteria have a similarly increased risk for postpartum glucose intolerance compared to GDM based on other diagnostic criteria. More studies with GDM based on the IADPSG criteria are needed to increase the quality of evidence concerning the long-term metabolic risk.

(1) Background: Breastfeeding has been shown to support glucose homeostasis in women after a pregnancy complicated by gestational diabetes mellitus (GDM) and is potentially effective at reducing long-term diabetes risk. (2) Methods: Data from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) study were analyzed to understand the influence of breastfeeding duration on long-term dysglycemia (prediabetes and diabetes) risk in women who had GDM in the index pregnancy. GDM and dysglycemia four to seven years postpartum were determined by the oral glucose tolerance test (OGTT). A Poisson regression model with a robust error variance was used to estimate incidence rate ratios (IRRs) for dysglycemia four to seven years post-delivery according to groupings of the duration of any breastfeeding (<1, ≥1 to <6, and ≥6 months). (3) Results: Women who had GDM during the index pregnancy and complete breastfeeding information and OGTT four to seven years postpartum were included in this study (n = 116). Fifty-one women (44%) had postpartum dysglycemia. Unadjusted IRRs showed an inverse association between dysglycemia risk and ≥1 month to <6 months (IRR 0.91; 95% confidence interval [CI] 0.57, 1.43; p = 0.68) and ≥6 months (IRR 0.50; 95% CI 0.27, 0.91; p = 0.02) breastfeeding compared to <1 month of any breastfeeding. After adjusting for key confounders, the IRR for the ≥6 months group remained significant (IRR 0.42; 95% CI 0.22, 0.80; p = 0.008). (4) Conclusions: Our results suggest that any breastfeeding of six months or longer may reduce long-term dysglycemia risk in women with a history of GDM in an Asian setting. Breastfeeding has benefits for mothers beyond weight loss, particularly for those with GDM.

The risk of major amputation is higher after urgently planned endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients with diabetes mellitus (DM). The aim of this nationwide cohort study was to compare outcomes between patients with and without DM following urgently planned open revascularization for CLTI from 2010 to 2014. Out of 1537 individuals registered in the Swedish Vascular Registry, 569 were registered in the National Diabetes Register. A propensity score adjusted Cox regression analysis was conducted to compare outcome between the groups with and without DM. Median follow-up was 4.3 years and 4.5 years for patients with and without DM, respectively. Patients with DM more often had foot ulcers ( p = 0.034) and had undergone more previous amputations ( p = 0.001) at baseline. No differences in mortality, cardiovascular death, major adverse cardiovascular events (MACE), or major amputation were observed between groups. The incidence rate of stroke was 70% higher (95% CI: 1.11–2.59; p = 0.0137) and the incidence rate of acute myocardial infarction (AMI) 39% higher (95% CI: 1.00–1.92; p = 0.0472) among patients with DM in comparison to those without. Open vascular surgery remains a first-line option for a substantial number of patients with CLTI, especially for limb salvage in patients with DM. The higher incidence rates of stroke and AMI among patients with DM following open vascular surgery for infrainguinal CLTI require specific consideration preoperatively with the aim of optimizing medical treatment to improve cardiovascular outcome postoperatively.

IntroductionThis study aimed to assess the validity of applying the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria for the diagnosis of gestational diabetes mellitus (GDM) at any time during pregnancy.Research design and methodsThis multicenter cohort study was conducted at five Japanese facilities from January 2018 to April 2019. The study cohort included women at a high risk of GDM who met one or more of the following IADPSG criteria during early pregnancy: fasting plasma glucose (FPG) ≥92 mg/dL and 75 g oral glucose tolerance test (OGTT) value of ≥180 mg/dL at 1 hour, or ≥153 mg/dL at 2 hour (hereafter early-onset GDM). Women diagnosed with early-onset GDM were followed up without therapeutic intervention and underwent the 75 g OGTT again during 24–28 weeks of gestation. Those exhibiting the GDM patterns on the second 75 g OGTT were diagnosed with true GDM and treated, whereas those exhibiting the normal patterns were diagnosed with false positive early GDM and received no therapeutic intervention.ResultsOf the 146 women diagnosed with early-onset GDM, 69 (47%) had normal 75 g OGTT values at 24–28 weeks of gestation, indicating a false-positive result. FPG levels were significantly higher in the first 75 g-OGTT test than in the second 75 g-OGTT test (93 mg/dL and 87.5 mg/dL, respectively; p<0.001). FPG levels were high in 86 (59%) women with early-onset GDM during early pregnancy but in only 39 (27%) women during mid-pregnancy. Compared with false positive early GDM, true GDM was more frequently associated with adverse pregnancy outcomes.ConclusionsAlthough women with early-onset GDM were followed up without treatment, the results of repeated 75 g OGTT during mid-pregnancy were normal in about 50%. Our data did not support the adoption of IADPSG thresholds for the diagnosis of GDM prior to 20 weeks of gestation.

BackgroundAlthough mild cognitive impairment is associated with an increased risk of developing dementia, there has been little work on its incidence and prevalence.AimsTo report age-specific prevalence, incidence and predictive validities for four diagnostic concepts of mild cognitive impairment.MethodA community sample of 1045 dementia-free individuals aged 75 years and over was examined by neuropsychological testing in a three-wave longitudinal study.ResultsPrevalence rates ranged from 3% to 20%, depending on the concept applied. The annual incidence rates applying different case definitions varied from 8 to 77 per 1000 person-years. Rates of conversion to dementia over 2.6 years ranged from 23% to 47%.ConclusionsMild cognitive impairment is frequent in older people. Prevalence, incidence and predictive validities are highly dependent on the diagnostic criteria applied.

Peripheral spondyloarthritis is a variant of spondyloarthritis which usually has a chronic course. There is an increased risk of cardiovascular diseases among patients with chronic inflammatory diseases in general. Coexisting diabetes mellitus can potentially add to the risk. The objective of this study was to determine the frequency of glucose intolerance in patients with spondyloarthritis The study was conducted among 35 participants with peripheral spondyloarthritis who visited the Department of Rheumatology, Enam Medical College & Hospital, Savar, Dhaka, Bangladesh from September, 2018 to January, 2020. The participants underwent either oral glucose tolerance test or estimation of HbA1C. The mean age of participants was 43.96 years. The majority (80%) of them were young to muddle-aged (≤40 years). 22.9% of the participants were prediabetic. Diabetes mellitus was found to be present in 37.1% of the participants. There was no significant difference between the study population and the general population in terms of frequency of prediabetes. But the frequency of diabetes in the study population was higher than that in the general population. There was no significant difference between males and females with regard to the frequencies of prediabetes and DM. Moreover, there was no significant difference in the frequencies of prediabetes and DM between young and middle-aged to elderly population. Considering the greater burden of DM among patients with peripheral spondyloarthritis across all age groups, routine screening for DM may be indicated in these individuals.

Abstract Background Individuals with established cardiovascular disease (CVD) and risk factors such as age, smoking, hypertension, and diabetes mellitus are at an increased risk of recurrent cardiovascular events and death. The incidence rate of recurrent CVD events varies between countries and populations. The United Arab Emirates (UAE) has one of the highest age-standardized death rates for CVD worldwide. The aim of our study was to estimate the incidence rates and determine the predictors of recurrent CVD events among UAE nationals. Methods We investigated an outpatient-based cohort of patients with a history of CVD visiting Tawam Hospital between April 1, 2008 and December 31, 2008. They were followed-up until July 31, 2018. Univariable and multivariable Cox proportional hazards regression models were used to determine the association between major CVD risk factors and the risk of CVD recurrence. Results A total of 216 patients (167 males, 49 females) with a history of CVD were included. They were followed for a median (interquartile range) of 8.1 (5.5–9.3) years, with a total of 1184 patient-years of follow-up. The overall incidence rate of recurrent CVD events was 92.1 per 1000 patient-years. The 8-year cumulative incidence was 73.7%. Age, female sex, and diabetes mellitus were significant predictors of recurrent CVD events, where females had a 1.96 times higher risk of recurrent CVD events than males. Conclusion Significant predictors of recurrent CVD events are older age, female sex, and diabetes mellitus. The incidence rate of recurrent CVD events was 92.1 per 1000 patient-years. Preventive measures, based on international guidelines for CVD management, may improve CVD morbidity and mortality in the UAE population.

Abstract Background Chronic inflammatory diseases have been linked to increased risk of atherothrombotic events, but the risk associated with inflammatory bowel disease (IBD) is conflictive. We, therefore, examined the risk of and risk factors for myocardial infarction (MI) and stroke in patients with IBD in Quebec. Methods We used the public health administrative database from the Province of Québec to identify newly diagnosed IBD patients between 1996 and 2015 with established case ascertainment algorithm. Incidence and prevalence of stroke and myocardial infarction were defined using ICD codes found in primary, secondary care visits or admission. Comorbidity analysis was performed by both using a logistic regression or a Poisson model with outcome rates for 1000 person-years adjusted for age and sex along with one comorbidity of interest, or with medical therapy as a time-varying variable. Significant variables (p &lt; 0.05) were added to a multivariable models along with age and sex. Analyses were run overall and stratified by disease type. Incidence rate ratios, 95% CIs and p-values were computed. Results In total, 34 644 newly diagnosed IBD patients (CD: 59.5%) were identified. The prevalence but not incidence rates of MI was higher in IBD (prevalence at the end on 2013: 3.98%, OR:2.03 95% CI: 1.92–2.15, incidence: 0.234 per 1000 patient-years) compared with the background Canadian rates (prevalence in 2012–2013: 2.0%, incidence: 0.220 per 1000 patient-years), while the prevalence and incidence rates of stroke were not significantly higher in IBD (prevalence in 2012–2013: 2.98%, OR: 1.15 95% CI:1.08–1.23, incidence: 0.122 per 1000 patient-years vs Canadian rates: (prevalence in 2012–2013: 2.60%, incidence: 0.297 per 1000 patient-years). We identified age, sex, hyperlipidaemia and hypertension (p &lt; 0.001 for each) as risk factors for developing MI and stroke in both CD and UC. Diabetes was identified as an additional risk factor for MI in CD and stroke in UC. Exposure to biologicals was associated with a higher incidence of MI compared with the non-treatment group (IRR: 1.51, 95% CI: 0.82–2.76, p = 0.07) in the insured IBD population. Conclusion Increased prevalence but not incidence of MI and no increased risk of stroke was identified in this population-based IBD cohort from Quebec. Risk factors for both MI and stroke included age, sex, hyperlipidaemia, hypertension and diabetes in IBD. Exposure to biologicals, reflecting disease severity in administrative databases, was associated with a higher incidence rate ratio for MI in IBD.
