Meta AnalysisEffect of Gabapentin Enacarbil on Individual Items of the International Restless Legs Study Group Rating Scale and Post-sleep Questionnaire in Adults with Moderate-to-Severe Primary Restless Legs Syndrome: Pooled Analysis of 3 Randomized Trials.
Few studies have investigated restless legs syndrome (RLS) treatment effects on individual International RLS Study Group Rating Scale (IRLS) items. We assessed the effects of gabapentin enacarbil (GEn) on individual IRLS items and their correlation with sleep disturbances in adults with moderate-to-severe primary RLS. ⋯ GEn significantly improved individual IRLS items and sleep disturbance versus placebo. Correlations between IRLS and PSQ items were moderate to strong. This was not a formal meta-analysis and was not powered to compare the GEn doses. Nevertheless, our study finds that the benefits of GEn extend to individual IRLS items and supports the importance of sleep quality in RLS treatment. ClinicalTrials.gov identifiers: NCT00298623, NCT00365352, and NCT01332305.

ReviewConcordant and Discordant EGFR Mutations in Patients With Multifocal Adenocarcinomas: Implications for EGFR-Targeted Therapy.
Adenocarcinoma remains the most common subtype of lung cancer in the United States. Most patients present with tumors that are invasive and often metastatic, but in some patients, multiple precursor in situ or minimally invasive adenocarcinoma tumors develop that can be synchronous and metachronous. These precursor lesions harbor the same spectrum of genetic mutations found in purely invasive adenocarcinomas, such as EGFR, KRAS, and p53 mutations. It is less clear, however, whether separate lesions in patients who present with multifocal disease share common underlying genetic driver mutations. ⋯ Our findings suggest that the emergence of the dominant EGFR driver alteration is often independent between lesions in patients with multifocal adenocarcinomas, and thus the same targeted therapy may not be effective for all lesions. However, genetic testing of multiple lesions can help to distinguish separate primary tumors from metastatic disease.

Randomized Controlled TrialEvaluation of Crushed Tablet for Oral Administration and the Effect of Food on Apixaban Pharmacokinetics in Healthy Adults.
These studies evaluate the relative bioavailability of crushed apixaban tablets and the effect of food on apixaban pharmacokinetic properties. ⋯ Apixaban tablets can be administered crushed or whole, with or without food. The results of these alternative methods of administration support their use in patients who have difficulty swallowing tablets. ClinicalTrials.gov identifiers: NCT02101112 and NCT01437839.
