ObjectivesRecent studies suggest that comprehensive smoking regulations to decrease exposure to second-hand smoke reduce the rates of acute myocardial infarction (AMI). The objective of this paper is to analyse if deaths due to AMI in Spain declined after smoking prevention legislation came into force in January 2006.DesignInformation was collected on deaths registered by the Instituto Nacional de Estadística for 2004–2007. Age- and sex-specific annual AMI mortality rates with 95% CIs were estimated, as well as age-adjusted annual AMI mortality rates by sex. Annual relative risks of death from AMI were estimated with an age-standardised Poisson regression model.ResultsAdjusted AMI mortality rates in 2004 and 2005 are similar, but in 2006 they show a 9% decline for men and a 8.7% decline for women, especially among those over 64 years of age. In 2007 there is a slower rate of decline, which reaches statistical significance for men (−4.8%) but not for women (−4%). The annual relative risk of AMI death decreased in both sexes (p<0.001) from 1 to 0.90 in 2006, and to 0.86 in 2007.ConclusionThe extension of smoke-free regulations in Spain was associated with a reduction in AMI mortality, especially among the elderly. Although other factors may have played a role, this pattern suggests a likely influence of the reduction in population exposure to second-hand smoke on AMI deaths.

The centralization of rectal cancer surgery has been associated with better quality of care and conformity with clinical guidelines. However, a more integrated model of care delivery is needed to strengthen the centralization strategy.

Aim The oncological risk/benefit trade‐off for laparoscopy in rectal cancer is controversial. Our aim was to compare laparoscopic vs open surgery for resection of rectal cancer, using unselected data from the public healthcare system of Catalonia (Spain). Methods This was a multicentre retrospective cohort study of all patients who had surgery with curative intent for primary rectal cancer at Catalonian public hospitals from 2011 to 2012. We obtained follow‐up data for up to 5 years. To minimize the differences between the two groups, we performed propensity score matching on baseline patient characteristics. We used multivariate Cox proportional hazards regression analyses to assess locoregional relapse at 2 years and death at 2 and 5 years. Results Of 1513 patients with Stage I–III rectal cancer, 933 (61.7%) had laparoscopy (conversion rate 13.2%). After applying our propensity score matching strategy (2:1), 842 laparoscopy patients were matched to 517 open surgery patients. Multivariate Cox analysis of death at 2 years [hazard ratio (HR) 0.65, 95% CI 0.48, 0.87; P = 0.004] and 5 years (HR 0.61, 95% CI 0.5, 0.75; P < 0.001) and of local relapse at 2 years (HR 0.44, 95% CI 0.27, 0.72; P = 0.001) showed laparoscopy to be an independent protective factor compared with open surgery. Conclusions Laparoscopy results in lower locoregional relapse and long‐term mortality in rectal cancer in unselected patients with all‐risk groups included. Studies using long‐term follow‐up of cohorts and unselected data can provide information on clinically relevant outcomes to supplement randomized controlled trials.
