TL;DR: The new standards set by the American Diabetes Association in 2011 recommend universal screening at 24–28 weeks of gestation and an oral glucose tolerance test with a diagnostic fasting plasma glucose of ≥92 mg/dL (4.5 mmol/L) (much lower than the World Health Organization criteria).
Abstract: How to screen and treat gestational diabetes mellitus (GDM) has always been controversial for clinicians and decision makers. The problem is complex, and the evidence is limited. The new standards set by the American Diabetes Association (ADA) in 2011 (1) recommend 1 ) universal screening at 24–28 weeks of gestation (2010 ADA standards recommended selective screening based on risk factors) and 2 ) an oral glucose tolerance test with a diagnostic fasting plasma glucose of ≥92 mg/dL (4.5 mmol/L) (much lower than the World Health Organization [WHO] criteria of ≥126 mg/dL [7.0 mmol/L] commonly used in clinical practice in Europe). Furthermore, diabetes is diagnosed when only one abnormal value is detected (whereas in the 2010 standards two …

TL;DR: Glycaemia and diabetes are rising globally, driven both by population growth and ageing and by increasing age-specific prevalences, and effective preventive interventions are needed, and health systems should prepare to detect and manage diabetes and its sequelae.

TL;DR: Although saxagliptin improves glycemic control, other approaches are necessary to reduce cardiovascular risk in patients with diabetes, and DPP-4 inhibition with saxgliptin did not increase or decrease the rate of ischemic events, though the rates of hospitalization for heart failure was increased.
Abstract: Background The cardiovascular safety and efficacy of many current antihyperglycemic agents, including saxagliptin, a dipeptidyl peptidase 4 (DPP-4) inhibitor, are unclear. Methods We randomly assigned 16,492 patients with type 2 diabetes who had a history of, or were at risk for, cardiovascular events to receive saxagliptin or placebo and followed them for a median of 2.1 years. Physicians were permitted to adjust other medications, including antihyperglycemic agents. The primary end point was a composite of cardiovascular death, myocardial infarction, or ischemic stroke. Results A primary end-point event occurred in 613 patients in the saxagliptin group and in 609 patients in the placebo group (7.3% and 7.2%, respectively, according to 2-year Kaplan–Meier estimates; hazard ratio with saxagliptin, 1.00; 95% confidence interval [CI], 0.89 to 1.12; P=0.99 for superiority; P<0.001 for noninferiority); the results were similar in the “on-treatment” analysis (hazard ratio, 1.03; 95% CI, 0.91 to 1.17).

TL;DR: A diagnosis of gestational diabetes mellitus (GDM) (diabetes diagnosed in the second or third trimester of pregnancy that is not clearly overt diabetes) or chemical-induced diabetes (such as in the treatment of HIV/AIDS or after organ transplantation)
Abstract: 1. Type 1 diabetes (due to b-cell destruction, usually leading to absolute insulin deficiency) 2. Type 2 diabetes (due to a progressive insulin secretory defect on the background of insulin resistance) 3. Gestational diabetes mellitus (GDM) (diabetes diagnosed in the second or third trimester of pregnancy that is not clearly overt diabetes) 4. Specific types of diabetes due to other causes, e.g., monogenic diabetes syndromes (such as neonatal diabetes and maturity-onset diabetes of the young [MODY]), diseases of the exocrine pancreas (such as cystic fibrosis), and drugor chemical-induced diabetes (such as in the treatment of HIV/AIDS or after organ transplantation)

TL;DR: In this paper, the authors compared a lifestyle intervention with metformin to prevent or delay the development of Type 2 diabetes in nondiabetic individuals. And they found that the lifestyle intervention was significantly more effective than the medication.
Abstract: Background Type 2 diabetes affects approximately 8 percent of adults in the United States. Some risk factors — elevated plasma glucose concentrations in the fasting state and after an oral glucose load, overweight, and a sedentary lifestyle — are potentially reversible. We hypothesized that modifying these factors with a lifestyle-intervention program or the administration of metformin would prevent or delay the development of diabetes. Methods We randomly assigned 3234 nondiabetic persons with elevated fasting and post-load plasma glucose concentrations to placebo, metformin (850 mg twice daily), or a lifestyle modification program with the goals of at least a 7 percent weight loss and at least 150 minutes of physical activity per week. The mean age of the participants was 51 years, and the mean body-mass index (the weight in kilograms divided by the square of the height in meters) was 34.0; 68 percent were women, and 45 percent were members of minority groups. Results The average follow-up was 2.8 years. The incidence of diabetes was 11.0, 7.8, and 4.8 cases per 100 person-years in the placebo, metformin, and lifestyle groups, respectively. The lifestyle intervention reduced the incidence by 58 percent (95 percent confidence interval, 48 to 66 percent) and metformin by 31 percent (95 percent confidence interval, 17 to 43 percent), as compared with placebo; the lifestyle intervention was significantly more effective than metformin. To prevent one case of diabetes during a period of three years, 6.9 persons would have to participate in the lifestyle-intervention program, and 13.9 would have to receive metformin. Conclusions Lifestyle changes and treatment with metformin both reduced the incidence of diabetes in persons at high risk. The lifestyle intervention was more effective than metformin.

TL;DR: The results indicate strong, continuous associations of maternal glucose levels below those diagnostic of diabetes with increased birth weight and increased cord-blood serum C-peptide levels.
Abstract: Background It is controversial whether maternal hyperglycemia less severe than that in diabetes mellitus is associated with increased risks of adverse pregnancy outcomes Methods A total of 25,505 pregnant women at 15 centers in nine countries underwent 75-g oral glucose-tolerance testing at 24 to 32 weeks of gestation Data remained blinded if the fasting plasma glucose level was 105 mg per deciliter (58 mmol per liter) or less and the 2-hour plasma glucose level was 200 mg per deciliter (111 mmol per liter) or less Primary outcomes were birth weight above the 90th percentile for gestational age, primary cesarean delivery, clinically diagnosed neonatal hypoglycemia, and cord-blood serum C-peptide level above the 90th percentile Secondary outcomes were delivery before 37 weeks of gestation, shoulder dystocia or birth injury, need for intensive neonatal care, hyperbilirubinemia, and preeclampsia Results For the 23,316 participants with blinded data, we calculated adjusted odds ratios for adverse pregnancy outcomes associated with an increase in the fasting plasma glucose level of 1 SD (69 mg per deciliter [04 mmol per liter]), an increase in the 1-hour plasma glucose level of 1 SD (309 mg per deciliter [17 mmol per liter]), and an increase in the 2-hour plasma glucose level of 1 SD (235 mg per deciliter [13 mmol per liter]) For birth weight above the 90th percentile, the odds ratios were 138 (95% confidence interval [CI], 132 to 144), 146 (139 to 153), and 138 (132 to 144), respectively; for cord-blood serum C-peptide level above the 90th percentile, 155 (95% CI, 147 to 164), 146 (138 to 154), and 137 (130 to 144); for primary cesarean delivery, 111 (95% CI, 106 to 115), 110 (106 to 115), and 108 (103 to 112); and for neonatal hypoglycemia, 108 (95% CI, 098 to 119), 113 (103 to 126), and 110 (100 to 112) There were no obvious thresholds at which risks increased Significant associations were also observed for secondary outcomes, although these tended to be weaker Conclusions Our results indicate strong, continuous associations of maternal glucose levels below those diagnostic of diabetes with increased birth weight and increased cord-blood serum C-peptide levels
