Randomized Controlled Trial Multicenter Study
Efficacy of different photoprotection strategies in preventing actinic keratosis new lesions after photodynamic therapy. The ATHENA study: a two-center, randomized, prospective, assessor-blinded pragmatic trial.
Background: Treatment of actinic keratosis (AK) and field cancerization with photodynamic therapy (PDT) is an effective therapeutic approach with a significant reduction in the number of AK lesions (-75% or more) associated with a significant cosmetic improvement of the photodamaged skin. Recently, also, the daylight PDT (DL-PDT) has proven to be as effective as the conventional PDT (C-PDT), but with a better tolerability. After C-PDT and DL-PDT it is advised to use photoprotection strategies to improve the clinical evolution and prevent the appearance of new AK lesions that usually appear 3-6 months after the last phototherapy session. ⋯ The percentage of subjects with an IGA score of 4/3 (very good or good) was 81% in the ACTX and 55% in the SS group (p = 0.06). Conclusion: In subjects with AK treated with C-PDT or DL-PDT, a "medicalized" photoprotection treatment is associated with a favorable clinical outcome with progressive reduction of lesions. In contrast to a very high photoprotection (SPF50+ or SPF100+/photolyase), the use of piroxicam 0.8%/SPF 50+ is associated with a significantly greater improvement in clinical evolution of AK lesions.

Randomized Controlled Trial Multicenter Study
Specific hypertension smartphone application to improve medication adherence in hypertension: a cluster-randomized trial.
Introduction: Digital interventions, such as smartphone applications (apps), are becoming an increasingly common way to support medication adherence and self-management in chronic illness. Aim: To evaluate the effectiveness of the intervention in pharmacological therapeutic adherence in mild to moderate arterial hypertension (AHT), through an app installed on a mobile phone, as well as the degree of control reached by the patient with this tool. Methods: Prospective, randomized controlled trial, full study and multicenter study. ⋯ The number of patients needed to treat to avoid non-adherence (NNT) was 4.23 patients. Conclusions: The intervention with an app installed on the mobile phones of hypertensive patients favors pharmacological therapeutic adherence and improves the percentage of hypertensive patient control. Trial registration: Spanish Agency of Medicine: EPA-SP UN-HTA-2015-01.

Randomized Controlled Trial Comparative Study
Comparative efficacy of first-line ceritinib and crizotinib in advanced or metastatic anaplastic lymphoma kinase-positive non-small cell lung cancer: an adjusted indirect comparison with external controls.
Objective: In the absence of head-to-head trials, this study indirectly compared progression free survival (PFS) and overall survival (OS) between ceritinib and crizotinib among patients with previously untreated advanced anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). Methods: A matching-adjusted indirect comparison method was implemented to adjust for cross-trial differences in patient characteristics between ASCEND-4 and PROFILE 1014 trials. Patient-level data from ASCEND-4 and published summary data from PROFILE 1014 were used. ⋯ Compared to crizotinib, ceritinib was associated with a significantly longer PFS (hazard ratio [95% confidence interval] (HR [CI]) = 0.64 [0.47-0.87]; median PFS: 25.2 vs 10.8 months, log-rank p-value = 0.003). OS did not differ significantly, with a HR of 0.82 [0.54-1.27] for ceritinib compared to crizotinib. Conclusions: In the adjusted indirect comparison with external controls, the second generation ALK inhibitor, ceritinib, was associated with a significantly prolonged PFS compared to crizotinib as first-line treatment for ALK-positive NSCLC.
