    Sleep is a fundamental human need, as essential to health as eating, drinking, and breathing. Contrary to the historical conception that sleep constitutes a passive condition of brain inactivity, it is understood to be a dynamic process regulated by active modulating pathways. During the sleep period, the brain exhibits various patterns of activity, including slow-wave sleep and rapid eye movement (REM) sleep. These patterns are closely linked to a range of physiological mechanisms in the body, spanning from hormonal and immune regulation to information processing and memory consolidation. The scientific community has shown interest in sleep and its related aspects. Thus, this research aims to explore and understand the interaction of sleep with memory, seeking to identify the involved systems and their implications for cognitive functioning. The adopted methodology consists of an exploratory and qualitative research approach using literature reviews. Information retrieval was conducted on reliable academic and scientific platforms, using specific descriptors to guide the careful selection of studies. The research results indicate that ensuring appropriate sleep quality, both in terms of adequate duration and timing, is crucial for preserving mental and physical health, quality of life, and safety. Moreover, it plays a supportive role in memory consolidation.Dormir é uma necessidade humana fundamental, tão essencial para a saúde quanto comer, beber e respirar. Contrariamente à concepção histórica de que o sono constitui uma condição passiva de inatividade cerebral, compreende-se que é um processo dinâmico e regulado por vias moduladoras ativas. Durante o momento do sono, o cérebro exibe diversos padrões de atividade, incluindo o sono de ondas lentas e o sono paradoxal. Esses padrões estão intimamente ligados a uma série de mecanismos fisiológicos do organismo, abrangendo desde a regulação hormonal e imunológica até o processamento de informações e a consolidação da memória. A comunidade científica tem manifestado interesse a respeito do sono e aos seus aspectos correlatos. Assim, esta pesquisa busca explorar e compreender a interação do sono com a memória, visando identificar os sistemas envolvidos e suas implicações no funcionamento cognitivo. A metodologia adotada consiste em uma pesquisa de natureza exploratória e qualitativa utilizando revisões de literatura. A busca por informações foi realizada em plataformas acadêmicas e científicas confiáveis, utilizando descritores específicos para orientar a seleção criteriosa de estudos. Os resultados da pesquisa indicam que garantir uma qualidade de sono apropriada, tanto em termos de duração adequada quanto nos momentos apropriados, é essencial para preservar a saúde mental, física, qualidade de vida e segurança, além de desempenhar uma função auxiliar na consolidação da memória

    Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
