Background Stroke has been the second major cause of death in Brazil in the last decades. A better understanding on epidemiological statistics as well as on the diseases burden is crucial for enabling stakeholders to better tackle the disease. Purpose This project aims to continuously monitor and evaluate the data sources on heart disease and stroke in Brazil to provide the most up-to-date information on the epidemiology of these diseases to Brazilian society annually. Methods This initiative is based on the Heart Disease & Stroke Statistics Update methodology of the American Heart Association, with the support of the Brazilian Society of Cardiology, the Global Burden of Diseases Brazil network and an international committee. The project incorporates official statistics provided by the Brazilian Ministry of Health and other government agencies, as well as data generated by other sources and scientific studies on heart disease, stroke, and other CVD, including GBD/IHME data. Results The age-standardized prevalence rates per 100.000 for ischemic stroke in 1990 was 1327,6 (1151.2 to 1516) and 870.1 (761.1 to 992.8) in 2019 representing a percent change of −34.5 (−36.7 to −0.3). The age-standardized prevalence rates for intracerebral hemorrhage in 1990 was 507.5 (438.9 to584.1) and 315.9 (275 to 361.4) in 2019 representing a percent change of −37.7 (−40.5 to −0.3). The age-standardized incidence rates for stroke in 1990 was 224.6 (201.6 to 251.8) and 127 (113.8 to 142.1) in 2019 representing a percent change of −43.5 (−44.7 to −0.4). the age-standardized mortality rates for stroke in 1990 was 137.8 (127.8 to 144) and 58.1 (52.6 to 61.8) in 2019 representing a percent change of −57.8 (−60.4 to −0.6). The age-standardized DALY rates for stroke in 1990 was 2959 (2829.6 to 3063) and 1219.6 (1142 to 1285.5) in 2019 representing a percent change of −58.8 (−61 to −0.6). Conclusion This project represents a fundamental step on a better understanding on the stroke epidemiology in Brazil. While we observed a significant decrease in mortality rates from 1990 to 2019, we also raise a concern on a possible shift for a plateau curve or even increased rates in the next years.

Due to their performance impact on program execution, cache replacement policies in set-associative caches have been studied in great depth. Currently, most general-purpose processors are multi-core, and among the very large corpus of research, and much to our surprise, we could not find any replacement policy that does actually take into account information relative to the sharing state of a cache way. Therefore, in this paper we propose to add, as a complement to the classical time-based related way-selection algorithms, an information relative to the sharing state and number of sharers of the ways. We propose several approaches to take this information into account, and our simulations show that LRU-based replacement policies can be slightly improved by them. Also, a much simpler policy, MRU, can be improved by our strategies, presenting up to 3.5× more IPC than baseline, and up to 82% less cache misses.
