Objective: Non-valvular atrial fibrillation (NVAF), a common cardiac arrhythmia, is associated with high morbidity and carries a substantial economic burden. Historically, vitamin K antagonists (VKAs; e.g. warfarin) have been used for therapy of NVAF, but recently several direct oral anticoagulants (DOACs) have been approved for prevention of stroke in patients with NVAF. This review summarizes the real-world evidence (RWE) for healthcare resource utilization (HRU) in patients receiving oral anticoagulants (VKAs and/or DOACs) for therapy of NVAF. ⋯ Bleed-related mortality in patients receiving oral anticoagulation for treatment of NVAF were low across all DOACs and warfarin. Conclusions: The limited available evidence for HRU burden among patients receiving oral anticoagulation for NVAF suggests that DOACs (particularly apixaban and dabigatran) offer some degree of benefit in terms of HRU outcomes, compared with warfarin. Further work is required to understand HRU outcomes in patients receiving DOACs.

Objective: To systematically assess benefits and harm of non-pharmacologic interventions for diabetic peripheral neuropathy (DPN) symptoms. Methods: MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from 1966 to May 24, 2016 for randomized controlled trials. Two reviewers evaluated studies for eligibility, serially abstracted data, evaluated risk of bias, and graded strength of evidence (SOE) for critical outcomes (pain and quality-of-life). ⋯ Conclusions: Alpha-lipoic acid and spinal cord stimulation were effective for pain; studies were short-term with quality deficits. Spinal cord stimulation had serious adverse events. Further research should address long-term outcomes and other non-pharmacologic treatments.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice and is associated with increased cardiovascular morbidity and mortality. Epicardial adipose tissue (EAT) serves as a biologically active organ with important endocrine and inflammatory function. Review An accumulating body of evidence suggests that EAT is associated with the initiation, perpetuation, and recurrence of AF, but the precise role of EAT in AF pathogenesis is not completely elucidated. Pathophysiological mechanisms involve adipocyte infiltration, profibrotic and pro-inflammatory paracrine effects, oxidative stress, neural mechanisms, and genetic factors. ⋯ Notably, EAT accumulation seems to be associated with stroke and adverse cardiovascular outcomes in AF. Weight loss, specific medications and ablation of ganglionated plexi (GP) seem to be potential therapies in this setting.

A systematic literature review was conducted comparing different approaches estimating persistence and adherence in chronic diseases with polypharmacy of oral and subcutaneous treatments. ⋯ Decisions on what method to use should be based on considerations of the route of medication administration, the resources available, setting and aim of the assessment. Combining different methods may provide wider insights into adherence and persistence, including patient behavior.

To assess the comparative efficacy and safety of cladribine tablets versus alternative disease modifying treatments (DMTs) in patients with active relapsing-remitting multiple sclerosis (RRMS), and in a subgroup with high disease activity (HRA + DAT), using systematic literature review (SLR) and network meta-analysis (NMA). ⋯ In this first NMA to consider cladribine tablets, ocrelizumab and daclizumab for treatment of RRMS, cladribine tablets are a comparatively effective and safe alternative to other DMTs in both active RRMS and HRA + DAT populations.
