Purpose: To assess safety and outcome of radiofrequency ablation (RFA) and microwave ablation (MWA) as compared to systemic chemotherapy and partial hepatectomy (PH) in the treatment of colorectal liver metastases (CRLM)., Methods: MEDLINE, Embase and the Cochrane Library were searched. Randomized trials and comparative observational studies with multivariate analysis and/or matching were included. Guidelines from National Guideline Clearinghouse and Guidelines International Network were assessed using the AGREE II instrument., Results: The search revealed 3530 records; 328 were selected for full-text review; 48 were included: 8 systematic reviews, 2 randomized studies, 26 comparative observational studies, 2 guideline-articles and 10 case series; in addition 13 guidelines were evaluated. Literature to assess the effectiveness of ablation was limited. RFA + systemic chemotherapy was superior to chemotherapy alone. PH was superior to RFA alone but not to RFA + PH or to MWA. Compared to PH, RFA showed fewer complications, MWA did not. Outcomes were subject to residual confounding since ablation was only employed for unresectable disease., Conclusion: The results from the EORTC-CLOCC trial, the comparable survival for ablation + PH versus PH alone, the potential to induce long-term disease control and the low complication rate argue in favour of ablation over chemotherapy alone. Further randomized comparisons of ablation to current-day chemotherapy alone should therefore be considered unethical. Hence, the highest achievable level of evidence for unresectable CRLM seems reached. The apparent selection bias from previous studies and the superior safety profile mandate the setup of randomized controlled trials comparing ablation to surgery.

Background: Understanding the effectiveness of treatment for depression in both the short term and long term is essential for clinical decision making. The present meta-analysis examined treatment effects on depression and quality of life in acute-phase psychotherapeutic interventions compared to no treatment control groups for adult depression at 6 months or longer postrandomization., Methods: A systematic literature search resulted in 44 randomized controlled trials with 6,096 participants. Acute-phase psychotherapy was compared to control groups at 6-month or longer postrandomization. Odds ratios of a positive outcome were calculated., Results: Psychotherapy outperformed control groups at 6 months or longer postrandomization (OR = 1.92, 95% CI: 1.60-2.31, P < .001). Heterogeneity was moderate (I²: 65, 95% CI: 53-74, P < .001). However, effects significantly decreased with longer follow-up periods. Additionally, a small positive effect of psychotherapy was observed for quality of life, while similar effects were obtained in separate analyses of each type of psychotherapy, with the exception of nondirective supportive therapy. Studies that provided booster sessions had better treatment results compared with studies that did not provide any further sessions. Finally, we found that trials on psychotherapy aimed at major depressive disorder (MDD) had better outcomes than those that were aimed at elevated depressive symptoms., Conclusions: There is substantial evidence that acute-phase psychotherapy results in a better treatment effects on depression and quality of life in the long term for adult patients with depression., (© 2016 Wiley Periodicals, Inc.)

Background: Birth weight of children born at term may theoretically be associated with risk of adverse events from immunization., Methods: We analyzed data on children born between April 1st 2002 and March 31st 2009 in the province of Ontario. Using the self-controlled case series design, we examined the risk of the combined endpoint of emergency room visit and hospital admission in the immediate three days post vaccination at 2 months of age compared to a control period 9-18 days after vaccination. In term children, we conducted 4 comparisons of relative incidence (RI) of events: (1) 4 lower birth weight quintiles compared to the largest quintile (2) SGA10 infants compared to non SGA10 infants, (3) low birth weight infants (<2500g) compared to non low birth weight infants and (4) SGA10 infants vaccinated before 60 days compared to those vaccinated after 60 days., Results: There was a significant trend towards increasing relative incidence of the combined endpoint with decreasing birth weight quintile (p=0.016). There was an increased relative incidence of events in SGA10 versus non SGA10 infants (RI 1.25 (95% CI 1.09-1.44)) and in SGA10 children vaccinated before 60 days of age compared to after 60 days of age (RI 1.57 (95% CI 1.14-2.18)). No significant effect was observed in low birth weight children. The impact of birth weight was primarily mediated through an increase in ER visits in the 24h following vaccination., Conclusion: Lower birth weight appears to be correlated with an increased risk of emergency room visits within 24h of vaccination. The absolute risk is small and there was no impact on admissions or death., (Copyright © 2011 Elsevier Ltd. All rights reserved.)

Introduction: The effectiveness of pandemic vaccine campaigns such as the H1N1 vaccine rollout is dependent on both the vaccines' effectiveness and the general public's willingness to be vaccinated. It is therefore critical to understand the factors that influence the decision of members of the public whether to get vaccinated with new, emergently released vaccines., Methods: A systematic review of English language quantitative surveys was conducted to identify consistent predictors of the decision to accept or decline any (pre)pandemic vaccine, including the H1N1 influenza A vaccine. A total of ten studies were included in this review and all pertained to the 2009 H1N1 influenza A pandemic. Respondents' willingness to receive a pandemic vaccine ranged from 8%-67% across the ten studies. The factors reported to be consistent predictors of the intention to vaccinate were: risk of infection, proximity or severity of the public health event, severity of personal consequences resulting from the illness, harm or adverse events from the vaccine, acceptance of previous vaccination, and ethnicity. Age and sex were the demographic variables examined most frequently across the ten studies and there was no consistent association between these variables and the intention to accept or reject a pandemic vaccine., Conclusion: Some predictors of the intention to accept or decline a (pre)pandemic vaccine or the H1N1 influenza A vaccine are consistently identified by surveys. Understanding the important factors influencing the acceptance of a pandemic vaccine by individual members of the public may help inform strategies to improve vaccine uptake during future pandemics.
