Objective: To implement and evaluate a regional prepregnancy care program in women with type 1 and type 2 diabetes.Research Design and Methods: Prepregnancy care was promoted among patients and health professionals and delivered across 10 regional maternity units. A prospective cohort study of 680 pregnancies in women with type 1 and type 2 diabetes was performed. Primary outcomes were adverse pregnancy outcome (congenital malformation, stillbirth, or neonatal death), congenital malformation, and indicators of pregnancy preparation (5 mg folic acid, gestational age, and A1C). Comparisons were made with a historical cohort (n = 613 pregnancies) from the same units during 1999-2004.Results: A total of 181 (27%) women attended, and 499 women (73%) did not attend prepregnancy care. Women with prepregnancy care presented earlier (6.7 vs. 7.7 weeks; P < 0.001), were more likely to take 5 mg preconception folic acid (88.2 vs. 26.7%; P < 0.0001) and had lower A1C levels (A1C 6.9 vs. 7.6%; P < 0.0001). They had fewer adverse pregnancy outcomes (1.3 vs. 7.8%; P = 0.009). Multivariate logistic regression confirmed that in addition to glycemic control, lack of prepregnancy care was independently associated with adverse outcome (odds ratio 0.2 [95% CI 0.05-0.89]; P = 0.03). Compared with 1999-2004, folic acid supplementation increased (40.7 vs. 32.5%; P = 0.006) and congenital malformations decreased (4.3 vs. 7.3%; P = 0.04).Conclusions: Regional prepregnancy care was associated with improved pregnancy preparation and reduced risk of adverse pregnancy outcome in type 1 and type 2 diabetes. Prepregnancy care had benefits beyond improved glycemic control and was a stronger predictor of pregnancy outcome than maternal obesity, ethnicity, or social disadvantage. [ABSTRACT FROM AUTHOR]

Objective: To determine whether using the chronic care model (CCM) in an underserved community leads to improved clinical and behavioral outcomes for people with diabetes.Research Design and Methods: This multilevel, cluster-design, randomized controlled trial examined the effectiveness of a CCM-based intervention in an underserved urban community. Eleven primary care practices, along with their patients, were randomized to three groups: CCM intervention (n = 30 patients), provider education only (PROV group) (n = 38), and usual care (UC group) (n = 51).Results: A marked decline in HbA(1c) was observed in the CCM group (-0.6%, P = 0.008) but not in the other groups. The magnitude of the association remained strong after adjustment for clustering (P = 0.01). The same pattern was observed for a decline in non-HDL cholesterol and for the proportion of participants who self-monitor blood glucose in the CCM group (non-HDL cholesterol: -10.4 mg/dl, P = 0.24; self-monitor blood glucose: +22.2%, P < 0.0001), with statistically significant between-group differences in improvement (non-HDL cholesterol: P = 0.05; self-monitor blood glucose: P = 0.03) after adjustment. The CCM group also showed improvement in HDL cholesterol (+5.5 mg/dl, P = 0.0004), diabetes knowledge test scores (+6.7%, P = 0.07), and empowerment scores (+2, P = 0.02).Conclusions: These results suggest that implementing the CCM in the community is effective in improving clinical and behavioral outcomes in patients with diabetes.

Objective: To evaluate the safety and efficacy of closed-loop insulin delivery in well-controlled pregnant women with type 1 diabetes treated with continuous subcutaneous insulin infusion (CSII).Research Design and Methods: A total of 12 women with type 1 diabetes (aged 32.9 years, diabetes duration 17.6 years, BMI 27.1 kg/m(2), and HbA(1c) 6.4%) were randomly allocated to closed-loop or conventional CSII. They performed normal daily activities (standardized meals, snacks, and exercise) for 24 h on two occasions at 19 and 23 weeks' gestation. Plasma glucose time in target (63-140 mg/dL) and time spent hypoglycemic were calculated.Results: Plasma glucose time in target was comparable for closed-loop and conventional CSII (median [interquartile range]: 81 [59-87] vs. 81% [54-90]; P = 0.75). Less time was spent hypoglycemic (<45 mg/dL [0.0 vs. 0.3%]; P = 0.04), with a lower low blood glucose index (2.4 [0.9-3.5] vs. 3.3 [1.9-5.1]; P = 0.03), during closed-loop insulin delivery.Conclusions: Closed-loop insulin delivery was as effective as conventional CSII, with less time spent in extreme hypoglycemia.

Objective: To assess random venous blood glucose (RBG) measurement at antenatal booking to detect "overt diabetes in pregnancy" (ODIP).Research Design and Methods: A retrospective analysis of regional hospital obstetric data from 2004-2008 was performed. Universal RBG screening was included at booking. Oral glucose tolerance test (OGTT) was administered if RBG >7.0 mmol/L or other indications, e.g., if a 50-g glucose challenge test was >7.7 mmol/L at 26-28 weeks. ODIP was based upon World Health Organization plasma glucose criteria for diabetes.Results: RBG data were collected from 17,852/26,369 (67.7%) pregnancies around the initial antenatal visit; 3,007 women had an OGTT. The receiver operator curve area under the curve for RBG to detect ODIP was 0.86 (0.80-0.92) (assuming women without an OGTT did not have ODIP).Conclusions: RBG at booking may provide a sufficiently sensitive screening tool for the detection of ODIP. We recommend further studies and comparison with fasting glucose and HbA(1c). [ABSTRACT FROM AUTHOR]
