Impact of Switching to Fingolimod Versus Injectable Disease-Modifying Therapy Cycling on Risk of Multiple Sclerosis-Related Relapses: A Retrospective Analysis.

Background: Clinical and real-world studies have shown significant reductions in multiple sclerosis (MS) relapses with fingolimod versus injectable disease-modifying therapies (DMTs). Multiple sclerosis relapse rate and incidence were compared in patients switching from an injectable DMT to fingolimod and those cycling from one injectable DMT to another or remaining on their original injectable DMT.

Methods: Retrospective analysis was performed using Commercial and Medicare Supplemental claims data (July 1, 2010, to June 30, 2016) of adults with MS receiving ≥1 injectable DMT.

Time to treatment failure following initiation of fingolimod versus teriflunomide for multiple sclerosis: a retrospective US claims study.

Disease modifying therapies (DMTs) for multiple sclerosis (MS) aim to delay progression and reduce relapses. Evidence is limited on the comparative effectiveness of the oral DMTs fingolimod and teriflunomide. This study evaluated time to treatment failure among patients with MS who initiated fingolimod versus teriflunomide in real-world settings.

A Review of Available Treatments, Clinical Evidence, and Guidelines for Diagnosis and Treatment of Pediatric Multiple Sclerosis in the United States.

Pediatric multiple sclerosis is associated with challenges in prompt diagnosis and uncertainty regarding optimal treatment. This review aimed to identify treatment guidelines or consensus statements for pediatric patients with multiple sclerosis, US Food and Drug Administration (FDA)-approved treatment options for pediatric multiple sclerosis, and any randomized controlled trials and observational studies examining available pharmacologic treatments in the pediatric multiple sclerosis population. Literature searches were performed in MEDLINE (1946-2016), EMBASE (1974-2016), and the Cochrane Central Register of Controlled Trials to identify treatment guidelines or consensus statements, pediatric multiple sclerosis treatment approvals, and randomized controlled trials and observation studies that examine the safety and effectiveness of available disease-modifying therapies.

Real-world durability of relapse rate reduction in patients with multiple sclerosis receiving fingolimod for up to 3 years: a retrospective US claims database analysis.

Objective: To assess real-world durability of reduction in relapse rates among patients with multiple sclerosis (MS) receiving fingolimod therapy over a longer-term period of follow-up.

Methods: Patients with MS who initiated fingolimod were identified from a US claims database (January 1, 2009 to September 30, 2016) and followed for 3 years post-initiation. Annualized relapse rates (ARRs) were calculated during the 1-year pre-initiation period, and during each year over the 3-year follow-up period.

Real-world persistence with fingolimod for the treatment of multiple sclerosis: A systematic review and meta-analysis.

Objective: To systematically review reports of fingolimod persistence in the treatment of relapsing-remitting multiple sclerosis (RRMS) across data sources and practice settings, and to develop a consensus estimate of the 1-year real-world persistence rate.

Methods: A systematic literature review was conducted (MEDLINE, EMBASE, and abstracts from selected conferences [2013-2015]) to identify observational studies reporting 1-year fingolimod persistence among adult patients with RRMS (sample size ≥50). A random-effects meta-analysis was performed to estimate a synthesized 1-year persistence rate and to assess heterogeneity across studies.

Cognitive and Functional Decline among Individuals 50 Years of Age or Older in Cambé, Paraná, Brazil: A Population-Based Study.

Aims: To identify the frequency of cognitive and functional decline (CFD) among adults 50 years of age and older by a population-based study.

Methods: Cognitive function was analyzed by the Mini-Mental State Examination, and the functional conditions were based on instrumental activities of daily living (IADL). Cases of CFD included individuals with cognitive decline and 2 or more compromised IADL.

Synthesis, antiproliferative activity and molecular properties predictions of galloyl derivatives.

The present study was designed to investigate the in vitro antiproliferative activity against ten human cancer cell lines of a series of galloyl derivatives bearing substituted-1,3,4-oxadiazole and carbohydrazide moieties. The compounds were also assessed in an in silico study of the absorption, distribution, metabolism and excretion (ADME) in the human body using Lipinski's parameters, the topological polar surface area (TPSA) and percentage of absorption (%ABS). In general, the introduction of N'-(substituted)-arylidene galloyl hydrazides 4-8 showed a moderate antitumor activity, while the 2-methylthio- and 2-thioxo-1,3,4-oxadiazol-5-yl derivatives 9 and 10 led to increased inhibition of cancer cell proliferation.
