INTRODUCTION: Guidelines recommend that perioperative beta-blockade be started days to weeks before surgery. Nonetheless, all randomized trials except for the controversial DECREASE trials started treatment ≤1 day before surgery, while most observational studies did not distinguish between long-term beta-blockade versus beta-blockers started for perioperative reasons. We thus conducted a population-based cohort study of the effectiveness of beta-blockade started within a clinically sensible period (8-60 days) before surgery. METHODS: Following research ethics approval, we conducted a cohort study of patients (≥66 years) who underwent major elective noncardiac surgery from 2003 and 2012 in Ontario, Canada. Propensity-score methods were used to form a matched cohort that reduced important differences between patients who started beta-blockers 8-60 days before surgery versus controls (no beta-blockers within 1 year before surgery). We measured the association of beta-blockade with 30-day (death, MI, stroke) and 1-year (death) outcomes post-surgery. Subgroup analyses were performed based on Revised Cardiac Risk Index class and history of prior CAD. RESULTS: The cohort included 4268 beta-blocked patients and 154,357 controls. Metoprolol (median daily dose 50 mg) was prescribed to 36% of beta-blocked patients, atenolol (median 25 mg) to 26%, and bisoprolol (median 5 mg) to 37%. In the matched cohort (n=8492), beta-blockade was not associated with death (RR 0.96; CI 0.70-1.32), MI (RR 0.92; CI 0.72-1.17), and stroke (RR 1.31; CI 0.68-2.52) at 30-days, or death at 1-year (Figure). Associations with outcomes did not differ significantly across subgroups. CONCLUSIONS: Outcomes were not altered in patients who start perioperative beta-blockade within a clinically sensible period before surgery. A large randomized trial is needed to determine if the continued use of perioperative beta-blockade in clinical practice is justified.

Abstract Purpose Incidence of breast cancer (BC), particularly in young women, are rising in India. Without population-based mammography screening, rising rates cannot be attributed to screening. Investigations are needed to understand the potential drivers of this trend. Methods An international team of experts convened to discuss the trends, environmental exposures, and clinical implications associated with BC in India and outlined recommendations for its management. Results Panels were structured across three major BC themes (n = 10 presentations). The symposium concluded with a semi-structured Think Tank designed to elicit short-term and long-term goals that could address the challenges of BC in India. Conclusion There was consensus that the prevalence of late-stage BC and the high BC mortality rates are associated with the practice of detection, which is primarily through clinical and self-breast exams, as opposed to mammography. Triple-Negative BC (TNBC) was extensively discussed, including TNBC etiology and potential risk factors, the limited treatment options, and if reported TNBC rates are supported by rigorous scientific evidence. The Think Tank session yielded long-term and short-term goals to further BC reduction in India and included more regional etiological studies on environmental exposures using existing India-based cohorts and case–control studies, standardization for molecular subtyping of BC cases, and improving the public’s awareness of breast health.

Long Term Mortality

AbstractWe aimed to investigate whether elevated liver enzymes in the adult population were associated with mortality due to infection. As a population-based cohort study, data from the National Health Insurance Service Health Screening Cohort were used. Adult individuals (aged ≥ 40 years) who underwent standardized medical examination between 2002 and 2003 were included, and infectious mortality was defined as mortality due to infection between 2004 and 2015. Aspartate transaminase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γ-GTP), AST/ALT ratio, and dynamic AST/ALT ratio (dAAR) were included in multivariable Cox modeling. A total of 512,746 individuals were included in this study. Infectious mortality occurred in 2444 individuals (0.5%). In the multivariable model, moderate and severe elevation in AST was associated with 1.94-fold [hazard ratio (HR):1.94, 95% confidence interval (CI) 1.71–2.19; P < 0.001] and 3.93-fold (HR: 3.93, 95% CI 3.05–5.07; P < 0.001) higher infectious mortality respectively, compared with the normal AST group. Similar results were observed for moderate and severe elevation in ALT and mild, moderate, and severe elevation in γ-GTP. Additionally, a 1-point increase in the AST/ALT ratio and dAAR was associated with higher infection mortality. Elevated liver enzymes (AST, ALT, AST/ALT ratio, γ-GTP, and dAAR) were associated with increased infectious mortality.
