Comparative Risk of Harm Associated With the Use of Targeted Immunomodulators: A Systematic Review.

Objective: To systematically compare the risk of adverse events (AEs) for 13 targeted immunomodulators (TIMs) indicated for ankylosing spondylitis (AS), inflammatory bowel diseases, juvenile idiopathic arthritis, plaque psoriasis, psoriatic arthritis (PsA), or rheumatoid arthritis (RA).

Methods: We searched electronic databases through July 2015 to retrieve randomized controlled trials (RCTs) and observational studies comparing AEs between 2 or more TIMs head-to-head. We reported on the following outcomes: number of AEs, discontinuation due to AEs, serious AEs, mortality, serious infections, tuberculosis, herpes zoster, and malignancies.

Information overload in healthcare: too much of a good thing?

The rapidly growing production of healthcare information - both scientific and popular - increasingly leads to a situation of information overload affecting all actors of the healthcare system and threatening to impede the adoption of evidence-based practice. In preparation for the 2015 Cochrane Colloquium in Vienna, we discuss the issues faced by three major actors of this system: patients, healthcare practitioners, and systematic reviewers. We analyze their situation through the concept of "filter failure", positing that the main problem is not that there is "too much information", but that the traditional means of managing and evaluating information are ill-suited to the realities of the digital age.

Barriers to and facilitators of interventions to counter publication bias: thematic analysis of scholarly articles and stakeholder interviews.

Background: When the nature and direction of research results affect their chances of publication, a distortion of the evidence base - termed publication bias - results. Despite considerable recent efforts to implement measures to reduce the non-publication of trials, publication bias is still a major problem in medical research. The objective of our study was to identify barriers to and facilitators of interventions to prevent or reduce publication bias.

A case study of pooled-studies publications indicated potential for both valuable information and bias.

Objectives: Pooled-studies publications (PSPs) present statistical analyses of multiple randomized controlled trials without a systematic literature search or critical appraisal. We explored the characteristics of PSPs and their potential impact on a systematic review (SR).

Study Design And Setting: We systematically evaluated PSPs excluded from an SR of second-generation antidepressants.

Adjunct ultrasonography for breast cancer screening in women at average risk: a systematic review.

Background: Screening with mammography has the ability to detect breast cancer at an early stage but misses some cancers. Supporters of adjunct ultrasonography to the screening regimen argue that it might be a safe and inexpensive approach to reduce the false-negative rates of screening. Critics are concerned that adjunct ultrasonography will also increase the rate of false-positive findings and can lead to unnecessary biopsies and treatments in women at average risk.

Comparative effectiveness of second-generation antidepressants for accompanying anxiety, insomnia, and pain in depressed patients: a systematic review.

Background: Patients with major depressive disorder (MDD) often suffer from accompanying symptoms that influence the choice of pharmacotherapy with second-generation antidepressants (SGAs). We conducted a systematic review to determine the comparative effectiveness of citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, desvenlafaxine, duloxetine, venlafaxine, bupropion, mirtazapine, nefazodone, and trazodone, for accompanying anxiety, insomnia, and pain in patients with MDD.

Methods: We conducted searches in multiple databases including MEDLINE®, Embase, the Cochrane Library, International Pharmaceutical Abstracts, and PsycINFO, from 1980 through August 2011 and reviewed reference lists of pertinent articles.
