Randomized Controlled Trial Multicenter Study
A randomized, double-blind, placebo-controlled, dose ranging study to assess the efficacy and safety of eltrombopag in patients receiving carboplatin/paclitaxel for advanced solid tumors.
Eltrombopag, an oral, nonpeptide thrombopoietin receptor agonist, has been shown to increase platelet counts in adults with chronic immune thrombocytopenia and chronic hepatitis C. This multicenter phase 2 study assessed the efficacy and safety of eltrombopag in patients receiving first-line carboplatin/paclitaxel for the treatment of advanced solid tumors. ⋯ This study provides preliminary information that eltrombopag does increase platelets in patients receiving chemotherapy for advanced solid tumors. Further investigation is needed to identify the optimal dose(s) and schedule of eltrombopag in patients receiving myelosuppressive chemotherapy.

Postherpetic neuralgia and painful diabetic peripheral neuropathy are common chronic neuropathic pain conditions associated with sleep disturbances. Pregabalin is indicated in the treatment of neuropathic pain. The objective of this review is to summarize the efficacy and safety of pregabalin in painful diabetic peripheral neuropathy and postherpetic neuralgia and the effect of pregabalin on sleep interference in these patients. ⋯ In addition to an analgesic benefit, pregabalin may decrease pain-related sleep interference in patients with painful diabetic peripheral neuropathy and postherpetic neuralgia.

Randomized Controlled Trial Multicenter Study
Diclofenac potassium liquid-filled soft gelatin capsules for the treatment of postbunionectomy pain.
Diclofenac potassium liquid-filled soft gelatin capsule (DPSGC) is a rapidly absorbed formulation of diclofenac approved for the treatment of mild to moderate acute pain in adults (≥18 years of age). The objective of this study was to investigate the efficacy and safety of DPSGC 25 mg in a multicenter, randomized, double-blind, placebo-controlled study in patients experiencing pain following first metatarsal bunionectomy. ⋯ These results indicate that DPSGC reduced pain in patients who underwent bunionectomy and this novel formulation of diclofenac potassium may be a practical option for treating mild to moderate acute pain.

While several studies have examined adherence to controller medications for the treatment of COPD, few systematic reviews have taken the translational step to identifying important and necessary areas for further research. The objective of this study was to review data on the outcomes of adherence to various controller therapies in patients with COPD in an effort to help prescribers understand adherence properties for each therapy. ⋯ Characteristics of the medication used (i.e. dosing schedule, formulation, etc.) as well as patient characteristics affect the adherence/persistence to medications for the treatment of COPD. Further patient education is necessary in order to effectively improve disease management and patient outcomes in COPD. There is a need for future research and educational efforts to improve adherence in COPD and more clearly identify specific behavioral and treatment characteristics associated with specific COPD medications that can facilitate adherence.

Randomized Controlled Trial
Impact of solifenacin on diary-recorded and patient-reported urgency in patients with severe overactive bladder (OAB) symptoms.
It is widely recognized that patient perception of overactive bladder (OAB) symptoms can vary considerably from mild to severe bother. This post hoc analysis reports outcomes in patients with severe OAB symptoms at baseline taken from the VESIcare Efficacy and Safety in PatieNts with Urgency Study (VENUS). ⋯ VENUS was a 12-week, randomized, double-blind, placebo-controlled trial of solifenacin (5 or 10 mg/day, flexibly dosed) in OAB patients. The primary endpoint in VENUS was mean change from baseline to study end in urgency episodes/day using 3-day bladder diaries. Secondary endpoints included other diary endpoints (frequency, incontinence, and nocturia), warning time (WT; time between first sensation of urgency to voiding), and patient-reported outcome (PRO) measures of urgency (the Indevus Urgency Severity Scale [IUSS] and Urgency Perception Scale [UPS]) and of symptom bother and health-related quality of life (HRQL) (the Patient Perception of Bladder Condition [PPBC] and Overactive Bladder Questionnaire). For this analysis, severe OAB was defined as baseline PPBC score ≥5 (1 = no problems, 6 = many severe problems).
