OBJECTIVETo evaluate factors associated with successful use of continuous glucose monitoring (CGM) among participants with intensively treated type 1 diabetes in the Juvenile Diabetes Research Foundation Continuous Glucose Monitoring Randomized Clinical Trial.RESEARCH DESIGN AND METHODSThe 232 participants randomly assigned to the CGM group (165 with baseline A1C ≥7.0% and 67 with A1C <7.0%) were asked to use CGM on a daily basis. The associations of baseline factors and early CGM use with CGM use ≥6 days/week in the 6th month and with change in A1C from baseline to 6 months were evaluated in regression models.RESULTSThe only baseline factors found to be associated with greater CGM use in month 6 were age ≥25 years (P < 0.001) and more frequent self-reported prestudy blood glucose meter measurements per day (P < 0.001). CGM use and the percentage of CGM glucose values between 71 and 180 mg/dl during the 1st month were predictive of CGM use in month 6 (P < 0.001 and P = 0.002, respectively). More frequent CGM use was associated with a greater reduction in A1C from baseline to 6 months (P < 0.001), a finding present in all age-groups.CONCLUSIONSAfter 6 months, near-daily CGM use is more frequent in intensively treated adults with type 1 diabetes than in children and adolescents, although in all age-groups near-daily CGM use is associated with a similar reduction in A1C. Frequency of blood glucose meter monitoring and initial CGM use may help predict the likelihood of long-term CGM benefit in intensively treated patients with type 1 diabetes of all ages.

In a double-blind multicentre trial in general practice, 144 patients with primary anxiety received daily treatment with mianserin or chlordiazepoxide, 30-60 mg, or placebo. There were no statistically significant differences in efficacy between the three treatments in the 106 patients who completed the 6-week trial. However, there was a substantial trend in favour of mianserin (P = 0.1), but not chlordiazepoxide, over placebo as assessed by the difference in overall improvement on the Hamilton Anxiety Scale. This trend may be clinically significant since more patients dropped out from the placebo group because of lack of effect or deterioration than did from the active treatment groups, particularly during the latter part of the trial. Side effects occurred to a similarly low extent with all treatments, except that mianserin caused more weight gain and, initially, more drowsiness than placebo, while placebo produced more nausea and vomiting. Taken together with the evidence from previous trials in patients with anxiety, these results support the notion that mianserin has anxiolytic properties.
