Multicenter Study Clinical Trial
An open-label multicenter study to assess the safety of dextromethorphan/quinidine in patients with pseudobulbar affect associated with a range of underlying neurological conditions.
Pseudobulbar affect (PBA) is associated with neurological disorders or injury affecting the brain, and characterized by frequent, uncontrollable episodes of crying and/or laughing that are exaggerated or unrelated to the patient's emotional state. Clinical trials establishing dextromethorphan and quinidine (DM/Q) as PBA treatment were conducted in patients with amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS). This trial evaluated DM/Q safety in patients with PBA secondary to any neurological condition affecting the brain. ⋯ DM/Q was generally well tolerated over this 52 week trial in patients with PBA associated with a wide range of neurological conditions.

Comparative Study
A mixed treatment comparison of gabapentin enacarbil, pramipexole, ropinirole and rotigotine in moderate-to-severe restless legs syndrome.
A mixed treatment comparison (MTC) was performed to investigate the relative efficacy and safety of licensed pharmaceuticals for moderate-to-severe restless legs syndrome (RLS). ⋯ This MTC confirmed the superiority of gabapentin enacarbil, pramipexole, ropinirole, and rotigotine above placebo in alleviating RLS symptoms. Compared to ropinirole, rotigotine showed some additional benefit in terms of change in IRLS at Week 12. Choice of RLS drugs requires careful evaluation of effectiveness and safety profiles in clinical practice. Due to lack of head-to-head trials, inconsistency could not be assessed in our analysis. Head-to-head trials on a more homogeneous population are needed to validate the MTC results.

To assess differences in psychological outcomes as well as risk and protective factors for these outcomes among several USA ethnic groups and identify correlates of these psychological outcomes among adults with diabetes in the second Diabetes Attitudes, Wishes and Needs (DAWN2 * ) study. ⋯ Ethnic groups differ in their psychological outcomes. The risk/protective factors for psychological outcomes differ across ethnic groups and different ethnic groups are more/less sensitive to their influence. These findings can aid the development of strategies to overcome the most prominent and influential psychosocial barriers to optimal diabetes care within each ethnic group.

To evaluate diabetes management in the real world, examining adherence to the American Diabetic Association (ADA) guidelines on frequency of glycated hemoglobin A1c (A1C) testing and antidiabetic treatment modifications in patients with type 2 diabetes and measuring the impact of adherence to the guidelines for achieving an A1C target <7%. ⋯ This study, based on real-world data from a large type 2 diabetes patient population, demonstrated that adherence to ADA guidelines for A1C testing frequency and drug treatment modifications was extremely low. Achievement of glycemic control (A1C <7%) was significantly associated with adherence to both A1C testing frequency and antidiabetic treatment modification guidelines. Limitations of this study include the retrospective nature, lack of important patient clinical information, and issues with incomplete source data.
