Assessing discrepancies in estimates of road traffic deaths in Brazil.

Introduction: The First UN Decade of Action for Road Safety (2011-2020) ended with most low/middle-income countries (LMICs) failing to reduce road traffic deaths. In contrast, Brazil reported a strong decline starting in 2012. However, comparisons with global health statistical estimates suggest that official statistics from Brazil under-report traffic deaths and overestimate declines.

Association between hospital safety-net burden and receipt of trimodality therapy and survival for patients with esophageal cancer.

Background: To examine the relationship between hospital safety-net burden and (1) receipt of surgery after chemoradiation (trimodality therapy) and (2) survival in esophageal cancer patients.

Methods: The National Cancer Database was queried to identify 22,842 clinical stage II to IVa esophageal cancer patients diagnosed in 2004 to 2015. The treatment facilities were categorized by proportion of uninsured/Medicaid-insured patients into percentiles.

Addressing discrepancies in estimates of road traffic deaths and injuries in Ethiopia.

Background: There are large discrepancies between official statistics of traffic injuries in African countries and estimates from the Global Burden of Disease (GBD) study and WHO's Global Status Reports on Road Safety (GSRRS). We sought to assess the magnitude of the discrepancy in Ethiopia, its implications and how it can be addressed.

Methods: We systematically searched for nationally representative epidemiological data sources for road traffic injuries and vehicle ownership in Ethiopia and compared estimates with those from GBD and GSRRS.

Estimates of road traffic deaths in Tanzania.

Introduction: There is considerable uncertainty in estimates of traffic deaths in many sub-Saharan African countries, with the Global Burden of Disease (GBD) and the Global Status Report on Road Safety (GSRRS) reporting widely differing estimates. As a case study, we reviewed and compared estimates for Tanzania.

Methods: We estimated the incidence of traffic deaths and vehicle ownership in Tanzania from nationally representative surveys.

Sex-based outcomes in surgical repair of acute type A aortic dissection: A meta-analysis and meta-regression.

Objective: Epidemiologic variation with respect to sex has been established in aortic dissection. However, current literature on sex-based outcomes in patients with aortic dissection is conflicting. In this study we aimed to compare perioperative outcomes according to sex in patients treated surgically for acute type A aortic dissection.
