Background Worldwide, smoking tobacco causes 7 million deaths annually, and this toll is expected to increase, especially in low-income and middle-income countries. In Latin America, smoking is a leading risk factor for death and disability, contributes to poverty, and imposes an economic burden on health systems. Despite being one of the most effective measures to reduce smoking, tobacco taxation is underused and cigarettes are more affordable in Latin America than in other regions. Our aim was to estimate the tobacco-attributable burden on mortality, disease incidence, quality of life lost, and medical costs in 12 Latin American countries, and the expected health and economic effects of increasing tobacco taxes.Methods In this modelling study, we developed a Markov probabilistic microsimulation economic model of the natural history, medical costs, and quality-of-life losses associated with the most common tobacco-related diseases in 12 countries in Latin America. Data inputs were obtained through a literature review, vital statistics, and hospital databases from each country: Argentina,

. Smoking-attributable burden of disease and costs to the health system are very high in Peru. Higher cigarette taxes could have substantial health and economic benefits for the country.

We found very low quality evidence showing that people with stable angina who received ranolazine as monotherapy had increased risk of presenting non-serious adverse events compared to those given placebo. We found low quality evidence indicating that people with stable angina who received ranolazine showed uncertain effect on the risk of cardiovascular death (for ranolazine given as monotherapy), all-cause death and non-fatal AMI, and the frequency of angina episodes (for ranolazine given as monotherapy) compared to those given placebo. Moderate quality evidence indicated that people with stable angina who received ranolazine showed uncertain effect on quality of life compared with people who received placebo. Moderate quality evidence also indicated that people with stable angina who received ranolazine as add-on therapy had fewer angina episodes but increased risk of presenting non-serious adverse events compared to those given placebo.

We found no evidence to assess the benefits and harms of early versus delayed EPO for the anaemia of ESKD.

The risk in the intervention group (and its 95% conf idence interval) is based on the assum ed risk in the com parison group and the relative effect of the intervention (and its 95% CI).CI: Conf idence interval; RR: Risk ratio GRADE Working Group grades of evidence High quality: We are very conf ident that the true ef f ect lies close to that of the estim ate of the ef f ect M oderate quality: We are m oderately conf ident in the ef f ect estim ate: The true ef f ect is likely to be close to the estim ate of the ef f ect, but there is a possibility that it is substantially dif f erent Low quality: Our conf idence in the ef f ect estim ate is lim ited: The true ef f ect m ay be substantially dif f erent f rom the estim ate of the ef f ect Very low quality: We have very little conf idence in the ef f ect estim ate: The true ef f ect is likely to be substantially dif f erent f rom the estim ate of ef f ect 4 Isolation as a strategy for controlling the transmission of hepatitis C virus (HCV) infection in haemodialysis units (Review)
