Hospital utilization and disposition among patients with malignant bowel obstruction: a population-based comparison of surgical to medical management.
In this study, the investigators sought to compare clinically meaningful outcomes in malignant bowel obstruction (MBO) patients treated with surgical versus medical management using population-based data. In this population-based analysis, medical management was associated with less hospital utilization at 30- and 90-days, fewer in-hospital deaths, and more frequent discharges to home. The authors suggest that these data underscore the potential benefits of medical management for MBO patients at the end-of-life.

Interventions for preventing thromboembolic events in patients with atrial fibrillation: a systematic review.
The purpose of this review was to compare the effectiveness of therapies to prevent thromboembolic events and bleeding complications in adults with nonvalvular atrial fibrillation (AF). Two independent reviewers screened citations in order to identify comparative studies of treatments to prevent stroke in adults with nonvalvular AF who reported thromboembolic or bleeding complications, then abstracted data from 220 selected articles, assessed study quality and applicability, and rated the strength of evidence. The article concludes that available direct-acting oral anticoagulants (DOACs) are at least as effective and safe as warfarin for patients with nonvalvular AF and had similar benefits across several patient subgroups.

Serum and plasma brain-derived neurotrophic factor and response in a randomized controlled trial of riluzole for treatment resistant depression.
In this paper, the authors report serum brain-derived neurotrophic factor (BDNF) and plasma BDNF levels from a randomized controlled, adjunctive, sequential parallel comparison design trial of riluzole in major depressive disorder. The investigators noted that preliminary evidence suggested that lower baseline BDNF may be associated with better clinical response to riluzole.

Performance of between-study heterogeneity measures in the Cochrane Library.
The growth in comparative effectiveness research and evidence-based medicine has increased attention to systematic reviews and meta-analyses. Assessing heterogeneity is critical for performing a meta-analysis and interpreting results. This article evaluates two heterogeneity measures. To evaluate these measures' performance empirically, the investigators applied them to 20,599 meta-analyses in the Cochrane Library.

Treatments of primary basal cell carcinoma of the skin: a systematic review and network meta-analysis.
The purpose of the study was to evaluate the comparative effectiveness and safety of treatments of primary basal cell carcinoma (BCC) in adults. The investigators concluded that surgical treatments and external-beam radiation have low recurrence rates for the treatment of low-risk BCC, but substantial uncertainty exists about their comparative effectiveness versus other treatments. Gaps remain regarding high-risk BCC subtypes and important outcomes, including costs.

Assessment of outcomes of treatment with oral anticoagulants in patients with atrial fibrillation and multiple chronic conditions: a comparative effectiveness analysis.
The purpose of this retrospective comparative effectiveness analysis was to determine whether there are differences in efficacy and safety of dabigatran, rivaroxaban, and warfarin regarding stroke prevention and bleeding rates, respectively, in elderly patients with atrial fibrillation (AF) with multiple chronic conditions (MCC). The investigators concluded that oral anticoagulants were similarly effective in stroke prevention among patients with AF with MCC. However, the indicate that dabigatran and rivaroxaban use may be associated with lower rates of mortality in patients with MCC.

Contemporary prostate cancer radiation therapy in the United States: patterns of care and compliance with quality measures.
This study measured compliance with quality measures for radiation therapy treatment of prostate cancer. The Comparative Effectiveness Analysis of Surgery and Radiation Study enrolled men who were treated for localized prostate cancer from 2011 and 2012. Medical records were reviewed, and patients completed surveys. Researchers concluded that men who received external beam radiation therapy (EBRT) were treated more appropriately than those treated with brachytherapy (BT). White men were also more likely to receive appropriate treatment than African-American and other minorities.

Long-term outcomes from repeated smoking cessation assistance in routine primary care.
This study assessed the importance of primary care support for smokers trying to quit. This retrospective, observational cohort study followed over 33,000 patients at six diverse health systems over 4 years. Long-term quit (LTQ) status (longer than 365 days) was measured, and it was determined that frequent visits (more than 75% of visits) had almost 3 times the success than patients who visited less than 25%.

Minimally invasive lung cancer surgery performed by thoracic surgeons as effective as thoracotomy.
The study authors hypothesized that the minimally invasive video-assisted thoracic surgery (VATS) approach to lobectomy for stage I lung cancer resulted in a longitudinal outcome that was not inferior to thoracotomy. After conducting their study, they concluded that the long-term efficacy of lobectomy for stage I lung cancer performed using the VATS approach by board-certified thoracic surgeons does not seem to be inferior to that of thoracotomy.

Effect of prostate cancer severity on functional outcomes after localized treatment: comparative effectiveness analysis of surgery and radiation study results.
The purpose of this study was to determine whether differences in predicted function over time between radical prostatectomy (RP) or external beam radiotherapy (EBRT) for localized cancer varied by risk group. Patient-reported, disease-specific function was measured using the Expanded Prostate Index Composite and predicted function was estimated using regression models, compared by disease risk. The study found that sexual function was similar between surgery and radiation for patients with high-risk disease, and the authors conclude that high-risk patients undergoing radiation therapy should be counseled that their sexual function may not be as good as low-risk patients also undergoing radiation.

Effectiveness of respiratory syncytial virus immunoprophylaxis in reducing bronchiolitis hospitalizations among high-risk infants.
This retrospective cohort study examined the effectiveness of respiratory syncytial virus (RSV) prophylaxis for infants born between 1996 and 2008. The infants were enrolled in the Kaiser Permanente Northern California integrated health system. Infants who ever received RSV immunoprophylaxis had a 32% decreased risk of bronchiolitis hospitalization and finants with chronic lung disease (CLD) had a 52% decreased risk. The 2014 American Academy of Pediatrics (AAP) guidelines changed recommendations for RSV immunoprophylaxis which made 48% of infants no longer eligible but nearly all infants with CLD would remain eligible.

Second arterial versus venous conduits for multi-vessel coronary artery bypass surgery in California.
This study sought to determine whether a second arterial conduit improves outcomes after multi-vessel coronary artery bypass grafting. It concluded that second arterial conduit use in California is low and declining, but arterial grafts were associated with significantly lower mortality and fewer cardiovascular events. A right internal thoracic artery graft offered no benefit over that of a radial artery, but did increase risk of sternal wound infection.

Association of inhaled corticosteroids and long-acting beta-agonists as controller and quick relief therapy with exacerbations and symptom control in persistent asthma: a systematic review and meta-analysis.
The authors conducted a systematic review and meta-analysis of the effects of single maintenance and reliever therapy (SMART) in patients with persistent asthma. They found that in patients with persistent asthma, the use of single maintenance and reliever therapy compared with inhaled corticosteroids as the controller therapy (with or without a long-acting beta-agonist) and short-acting beta-agonists as the relief therapy was associated with a lower risk of asthma exacerbations.

Generalized boosted modeling to identify subgroups where effect of dabigatran versus warfarin may differ: an observational cohort study of patients with atrial fibrillation.
The purpose of this study was to explore generalized boosted modeling (GBM) as a method for identifying subgroups with greater benefit or harm with dabigatran versus warfarin for treatment of atrial fibrillation. The investigators concluded that dabigatran's superiority to warfarin at prevention of thromboembolism may be greater in secondary than primary prevention. They indicated that in practice, secondary prevention patients are more often treated with warfarin.
