A mixed meal effectively elevates postprandial glycemia after 4-6 h. Dual-wave insulin bolus, in which insulin is calculated for both the carbohydrates and fat proteins, is effective in controlling postprandial glycemia.

Continuous subcutaneous insulin infusion vs. multiple daily injections in children with type 1 diabetes: a systematic review and meta-analysis of randomized control trials. Pediatric Diabetes 2009: 10: 52-58.Objective: To investigate potential effects of continuous subcutaneous insulin infusion (CSII) compared with multiple daily injections (MDI) on glycemic control in children with type 1 diabetes mellitus (T1DM). Study design: Meta-analysis and systematic review of randomized control studies (RCTs). The electronic databases MEDLINE, Cochrane Library, and EMBASE were searched through October 2007. Results: Six RCTs involving 165 participants with T1DM met our predefined inclusion criteria. Combined data from all trials showed that the CSII group compared with the MDI group experienced a significant reduction in the level of glycosylated hemoglobin. The pooled weighted mean difference (WMD) was 20.24% [95% confidence interval (95% CI) 20.41 to 20.07, p , 0.001] with a fixed model and remained significant in the random effect model. This effect was reached by slightly decreasing insulin requirement [three RCTs, n ¼ 74, WMD 20.22 IU/kg/d (95% CI 20.31 to 20.14, p , 0.001)]. No differences in the incidences of ketoacidosis and severe hypoglycemic events were found. Conclusions: In short-term insulin therapy, CSII compared with MDI is a more effective form of metabolic control and allows reducing the daily insulin requirement. Yet, no conclusions have been made so far whether this effect holds in later years. These results should be approached with caution because of the methodological limitations of the analyzed studies.

Patients using at least one D-W/S-W bolus per day achieved a recommended level of HbA1c. Paediatric patients with type 1 diabetes mellitus were found to be able to apply D-W/S-W boluses in daily self-treatment process based on food counting.

Bolus calculators are effective tools in controlling blood glucose levels in patients treated with insulin. Diabetics is a new software devised for patients to facilitate and improve self-managing for prandial insulin dosing and for better controlling food intake. This device contains two integral parts: a nutrition database and a bolus calculator. The algorithm is based on a formula in which carbohydrate (CHO) and either fat and/or protein (FP) products are engulfed in insulin. The insulin dose setting is programmed individually for CHO in a normal bolus (N-W) and for FP in a square-wave bolus (S-W). The device calculates the dose of insulin for N-W or S-W, suggests the optimal kind of bolus, and indicates the timing in hours for an S-W bolus. In addition, this calculator, which contains a nutrition database and insulin dosing software, helps determine the correct type of necessary boluses for selected foods.

The use of the Diabetics software by patients educated at the WPTS is safe and reduces 2-h postprandial BGL's and glucose variability.
