Pharmacologic interventions for infantile hemangioma: a meta-analysis.
The objective of this report was to meta-analyze studies of pharmacologic interventions for children with infantile hemangiomas (IH). It concluded that propranolol was effective at reducing IH size compared with placebo, observation, and other treatments including steroids in most studies. Corticosteroids demonstrated moderate effectiveness at reducing IH size/volume.

The comparative harms of open and robotic prostatectomy in population based samples.
Using population cohort data,the researchers examined sexual and urinary function in men undergoing open radical prostatectomy vs those undergoing robotic assisted radical prostatectomy. They found that men undergoing robotic assisted radical prostatectomy likely experience less decline in early urinary continence and sexual function than those undergoing open radical prostatectomy.

Effectiveness and safety of aldosterone antagonist therapy use among older patients with reduced ejection fraction after acute myocardial infarction.
The purpose of this paper is to describe how aldosterone antagonist treatment is used among older myocardial infarction (MI) patients in routine practice. They found that aldosterone antagonist use was not associated with lower mortality except in symptomatic HF patients, and risks of hyperkalemia were low at 30 days, but significantly higher among patients prescribed aldosterone antagonists, as was risk of acute renal failure compared with patients not prescribed aldosterone antagonists. They concluded that these results underscore the importance of close post-discharge monitoring of this patient population.

Meta-analysis of studies with bivariate binary outcomes: a marginal beta-binomial model approach.
In this paper, the researchers propose a marginal beta-binomial model for the meta-analysis of studies with binary outcomes. This model is based on the composite likelihood approach and has several attractive features compared with the existing models such as bivariate generalized linear mixed model (Chu and Cole, 2006) and Sarmanov beta-binomial model (Chen et al., 2012).

Average effect estimates remain similar as evidence evolves from single trials to high-quality bodies of evidence: a meta-epidemiologic study.
The objective of this study was to use a diverse sample of medical interventions to assess empirically whether first trials rendered substantially different treatment effect estimates than reliable, high-quality bodies of evidence. It concluded that results of first trials often change, but the magnitude of change, on average, is small. Exceptions are first trials that present large treatment effects, which often dissipate as new evidence accrues.

Baseline disability and poor functioning in bipolar disorder predict worse outcomes: results from the Bipolar CHOICE study.
This study examined the effects of treatment on functioning impairments and quality of life and assessed baseline functioning and employment status as predictors of treatment response in symptomatic individuals from the Bipolar Clinical Health Outcomes Initiative in Comparative Effectiveness (Bipolar CHOICE) study. It found that prior disability status was associated with a worse treatment response and prospective illness course.

Bipolar CHOICE (Clinical Health Outcomes Initiative in Comparative Effectiveness): a pragmatic 6-month trial of lithium versus quetiapine for bipolar disorder.
The purpose of this trial was to compare lithium and second-generation antipsychotics. The investigators found that outcomes with lithium + APT and quetiapine + APT were not significantly different across 6 months of treatment for bipolar disorder.

Comparative effectiveness of implantable cardioverter defibrillators for primary prevention in women.
The researchers examined clinical practice data to compare survival rates among women with heart failure with or without a primary prevention implantable cardioverter defibrillator (ICD). Theyn found that among patients with heart failure with reduced left ventricular ejection fraction, a primary prevention ICD was associated with a significant survival advantage among women and among men.

Comparative risk of hospitalized infection associated with biologic agents in rheumatoid arthritis patients enrolled in Medicare.
The aim of this study was to determine whether the associated risk of hospitalized infections differed between specific biologic agents used to treat rheumatoid arthritis (RA). It concluded that RA patients with prior exposure to a biologic agent, exposure to etanercept, infliximab, or rituximab was associated with a greater 1-year risk of hospitalized infection compared with the risk associated with exposure to abatacept.

Comparative short-term safety of sodium ferric gluconate versus iron sucrose in hemodialysis patients.
Despite different pharmacologic properties, little is known about the comparative safety of sodium ferric gluconate versus iron sucrose in hemodialysis patients. This study found that, overall, the 2 iron formulations studied exhibited similar safety profiles; however, ferric gluconate was associated with a slightly decreased risk for infection-related outcomes compared to iron sucrose among patients with a hemodialysis catheter.

Diagnostic performance of cardiac magnetic resonance imaging and echocardiography in evaluation of cardiac and paracardiac masses.
The researchers evaluated the predictive value of echocardiography and cardiac magnetic resonance (CMR) imaging parameters to identify tumors and malignancy and to provide histopathologic diagnosis of cardiac masses. They found that CMR identified 6 masses missed on transthoracic echocardiography (4 of which were outside the heart) and provided significantly more correct histopathologic diagnoses compared to echocardiography (77 percent vs 43 percent).

Impact of hematopoietic growth factors on blood transfusion needs, incidence of neutropenia, and overall survival among elderly advanced ovarian cancer patients treated with chemotherapy.
The researchers sought to determine the effectiveness of erythropoietin-stimulating agent (ESA) and granulocyte colony-stimulating factor (CSF) in reducing blood transfusion needs and neutropenia incidence in community-dwelling elderly ovarian cancer patients. They found that erythropoietin-stimulating agents were effective in reducing blood transfusion need. Granulocyte colony-stimulating factors were effective in lowering neutropenia incidence and also were associated with improved survival in elderly ovarian cancer patients.

The comparative effectiveness of diabetes prevention strategies to reduce postpartum weight retention in women with gestational diabetes mellitus: the gestational diabetes' effects on moms (GEM) cluster randomized controlled trial.
The researchers compared the effectiveness of diabetes prevention strategies addressing postpartum weight retention for women with gestational diabetes mellitus (GDM) delivered at the health system level: mailed recommendations (usual care) versus usual care plus a Diabetes Prevention Program (DPP)-derived lifestyle intervention. They found that a DPP-derived lifestyle intervention modestly reduced postpartum weight retention and increased vigorous-intensity physical activity.
