DIAGNÓSTICO QUALI-QUANTITATIVO DA ARBORIZAÇÃO URBANA DO BAIRRO PANTANAL DO MUNICÍPIO DE MACAPÁ-AP
Este trabalho teve como objetivo realizar um inventário quali-quantitativo da arborização urbana do bairro Pantanal, Macapá, AP. Portanto, foram avaliados as condições arbóreas através dos parâmetros: porte arbóreo das espécies identificadas, disposição do fuste, presença de fios elétricos sob as árvores e calçamento adequada, por meio de índices de diversidade de Shannom e Simpsom foram avaliados a riqueza de espécies, e foi delimitada a área das copas e a cobertura arbórea por rua. Foram identificados 144 indivíduos arbóreo, sendo 17 espécies, pertencentes a 9 famílias botânicas. As espécies Mangifera indica L. e Cocos nucifera L. totalizaram 59% de indivíduos. A maioria dos indivíduos apresentam altura de até 5 m. Foi observado que 67,36 % dos indivíduos apresentaram fuste reto. Quanto que 68,06% estão com calçamento inadequado. Constatou-se que 77,78% da população vegetal encontra-se livre de fiação elétrica. O índice de Shannon (1,94) foi considerado baixo e o índice Simpson (0,79) indicou alta dominância de uma única espécie. A arborização em relação as copas foram insuficientes para proporcionar conforto térmico e sombreamento adequado. Conclui-se que arborização do bairro Pantanal encontra-se no estado juvenil, a maioria da vegetação no bairro é de espécies exóticas, a maioria das árvores não apresentam problemas fisionômicos.

Quali-quantitative diagnosis of urban arborization in the Pantanal Neighborhood of the municipality of Macapá, Amapá, Brazil
ABSTRACT: This study aimed to conduct a qualitative and quantitative inventory of urban afforestation in the Pantanal neighborhood, Macapá, AP. Therefore, the tree conditions were evaluated through the parameters: tree size of the identified species, stem arrangement, presence of electrical wires under the trees and adequate pavement, using Shannom and Simpsom diversity indexes, the species richness was evaluated, and the crown area and the tree cover per street were delimited. 144 tree species were identified, 17 species, belonging to 9 botanical families. The species Mangifera indica L. and Cocos nucifera L. totaled 59% of individuals. Most individuals are up to 5 m tall. It was observed that 67.36% of the individuals had a straight shaft. As 68.06% are with inadequate paving. It was found that 77.78% of the plant population is free of electrical wiring. The Shannon index (1.94) was considered low and the Simpson index (0.79) indicated high dominance of a single species. The afforestation in relation to the crowns was insufficient to provide thermal comfort and adequate shading. It is concluded that the afforestation of the Pantanal neighborhood is in the juvenile state, most of the vegetation in the neighborhood is of exotic species, most of the trees do not present physiognomic problems.

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)
