INOVAÇÃO SOCIAL E SUSTENTABILIDADE: CONSUMO DE ENERGIA ELÉTRICA EM COMUNIDADES CARENTES NO BRASIL

This study aims to understand the universalization of electricity consumption by poor communities in Brazil and raise the legal aspects and the universalization of electricity sector. The methodological procedures were based on qualitative strategy and documents analisys of two cases. Was used indicators of disadvantaged communities and sustainable energy development. The results show a tendency to make the power sector more socially inclusive, particularly for services universalization.Este trabalho objetiva compreender a universalização do consumo de energia elétrica por comunidades carentes no Brasil, levantar os aspectos legais e a universalização do setor de energia elétrica. Os procedimentos metodológicos basearam-se em estratégia qualitativa de base documental de dois casos estudados. Foram utilizados indicadores de comunidades desfavorecidas e de desenvolvimento energético sustentável. Tem-se uma tendência de tornar o setor elétrico socialmente mais inclusivo, principalmente pela universalização dos serviços

Increase of invasive meningococcal serogroup W disease in Europe, 2013 to 2017

Background: The total incidence of invasive meningococcal disease (IMD) in Europe has been declining in recent years; however, a rising incidence due to serogroup W (MenW), predominantly sequence type 11 (ST-11), clonal complex 11 (cc11), was reported in some European countries. Aim: The aim of this study was to compile the most recent laboratory surveillance data on MenW IMD from several European countries to assess recent trends in Europe. Methods: In this observational, retrospective study, IMD surveillance data collected from 2013–17 by national reference laboratories and surveillance units from 13 European countries were analysed using descriptive statistics. Results: The overall incidence of IMD has been stable during the study period. Incidence of MenW IMD per 100,000 population (2013: 0.03; 2014: 0.05; 2015: 0.08; 2016: 0.11; 2017: 0.11) and the proportion of this serogroup among all invasive cases (2013: 5% (116/2,216); 2014: 9% (161/1,761); 2015: 13% (271/2,074); 2016: 17% (388/2,222); 2017: 19% (393/2,112)) continuously increased. The most affected countries were England, the Netherlands, Switzerland and Sweden. MenW was more frequent in older age groups (≥ 45 years), while the proportion in children (< 15 years) was lower than in other age groups. Of the culture-confirmed MenW IMD cases, 80% (615/767) were caused by hypervirulent cc11. Conclusion: During the years 2013–17, an increase in MenW IMD, mainly caused by MenW cc11, was observed in the majority of European countries. Given the unpredictable nature of meningococcal spread and the epidemiological potential of cc11, European countries may consider preventive strategies adapted to their contexts.info:eu-repo/semantics/publishedVersio

Outcomes from elective colorectal cancer surgery during the SARS-CoV-2 pandemic

This study aimed to describe the change in surgical practice and the impact of SARS-CoV-2 on mortality after surgical resection of colorectal cancer during the initial phases of the SARS-CoV-2 pandemic

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

One-year evaluation of inactive occlusal enamel lesions in children and adolescents.

OBJECTIVES: The aims of this study were to compare caries incidence and progression on sound occlusal surfaces and on surfaces presenting inactive enamel lesions in children and adolescents over 1 year and to estimate the risk of caries incidence and progression on these surfaces. METHODS: This prospective cohort study followed 200 7-15-year-old caries-inactive schoolchildren over 1 year. Stage of eruption, occlusal plaque, and occlusal caries were recorded on permanent molars. Statistical analysis was performed using generalized estimating equations with a logistic link function. RESULTS: Twenty-two children (11 %) presented "caries progression" (at least one active lesion on molar teeth). At site level, no difference was observed in caries incidence and progression between sites classified either sound (2.6 %) or with inactive enamel lesion (3.9 %) at the baseline examination (χ (2) test, p = 0.48). Adjusted for plaque, stage of eruption, type of molar and dental arch, inactive enamel lesions presented a similar risk for caries progression than sound occlusal surfaces (OR = 0.98, 95 % CI = 0.40-2.38). CONCLUSION: Within the limitations of this study, no difference was observed in caries incidence, progression, and risk on sound occlusal sites in comparison with sites presenting inactive enamel lesions. CLINICAL RELEVANCE: Occlusal surfaces harboring inactive caries lesions did not require additional attention than the one normally given to sound occlusal surfaces over a 1-year period
