Inundações no município do Porto em janeiro de 2023: avaliação baseada numa revisão de literatura

Neste trabalho, foram analisadas as inundações ocorridas no Porto - Portugal em 7 de janeiro de 2023, que resultaram em um intenso escoamento superficial devido à forte precipitação. Para entender melhor as causas dessas inundações, realizamos uma revisão da literatura. Através de pesquisas em plataformas Google Scholar e Science Direct, identificamos 14 referências relevantes, incluindo artigos científicos e dissertações de mestrado, que abordam estratégias de mitigação e prevenção de inundações urbanas. Essas estratégias envolvem melhorias na infraestrutura de drenagem, planejamento urbano sustentável, sistemas de alerta precoce e conscientização pública sobre os riscos. No dia 7 de janeiro de 2023, a cidade enfrentou uma série de inundações que resultaram em danos materiais significativos. As áreas mais afetadas incluíram não apenas a rua Mouzinho da Silveira, mas também a rua Barão de Forrester e a rua dos Clérigos. Essas regiões foram particularmente atingidas pelo avanço das águas, causando danos consideráveis e prolongando os efeitos das inundações na cidade. As estratégias propostas, como a limpeza dos detritos das obras do metro, estudos hidrológicos e melhorias nas infraestruturas e sistemas de drenagem, podem ajudar a prevenir inundações futuras. Também é importante conscientizar a população sobre o risco de inundações e promover a participação de todos na definição e implementação das estratégias. Conclui-se que a implementação integrada dessas estratégias pode fortalecer a resiliência do Porto às inundações, minimizando danos materiais e riscos à segurança.In this work, we analyzed the floods that occurred in Porto - Portugal on January 7, 2023, which resulted in intense surface runoff due to heavy precipitation.To better understand the causes of these floods, we conducted a literature review. Through searches on Google Scholar and Science Direct platforms, we identified 14 relevant references, including scientific articles and master theses, that address mitigation and prevention strategies for urban flooding. These strategies involve improvements in drainage infrastructure, sustainable urban planning, early warning systems and public awareness of the risks. On January 7, 2023, the city faced a series of floods that resulted in significant material damage. The most affected areas included not only Mouzinho da Silveira Street but also Barão de Forrester Street and Cl�\xA9rigos Street. These regions were particularly impacted by the advancing waters, causing considerable damage and prolonging the effects of the floods in the city. The proposed strategies, such as cleaning debris from the metro works, hydrological studies and improvements in infrastructure and drainage systems, can help prevent future flooding. It is also important to make the population aware of the risk of flooding and to promote everyone's participation in defining and implementing the strategies. It is concluded that the integrated implementation of these strategies can strengthen the Porto's resilience to flooding, minimizing material damage and safety risks. The adaptation of these strategies to local characteristics and the collaboration between government authorities, urban planning experts and local communities are essential to address the challenges and promote effective flood management in Porto

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

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)
