SRP induced bacteraemia associated with anaerobic bacteria, especially in patients with periodontal disease.

Geographic regions do not influence the microbiota, but the microbiota may vary by geographic region. P. gingivalis, T. forsythensis, and C. rectus are the most prevalent periodontophatic microorganisms in Colombia. A. actinomycetemcomitans was more common in AgP, and a large percentage of the population studied had enteric rods in the subgingival plaque.

Introducción. Los microorganismos involucrados en la periodontitis varían en cada región dependiendo de diferentes factores. Por ello cada país debe establecer su propio perfil microbiológico con el objeto de proponer esquemas adecuados de prevención y tratamiento. Objetivo. Investigar la presencia y concentración subgingival de Porphyromonas gingivalis, Tannerella forsythia, Actinobacillus actinomycetemcomitans, Prevotella intermedia/Prevotella nigrescens, Eikenella corrodens, Campylobacter rectus, Micromonas micros, Fusobacterium spp, Dialister pneumosintes y bacilos entéricos en pacientes con periodontitis en una población colombiana considerando edad, género y nivel socioeconómico. Materiales y métodos. Participaron 183 pacientes: 84 con periodontitis crónica, 59 con periodontitis agresiva y 40 individuos sanos. De cada paciente se obtuvo un grupo de muestras de los seis sitios con mayor profundidad de bolsa que se procesaron por cultivo para el aislamiento e identificación de las bacterias. Resultados. En periodontitis crónica y agresiva se detectaron con alta y similar frecuencia P. gingivalis, T. forsythia, P. intermedia/P. nigrescens, C. rectus, Fusobacterium spp y E. corrodens y con menor y similar frecuencia, M. micros, A. actinomycetemcomitans, D. pneumosintes y bacilos entéricos, principalmente de la tribu Klebsielleae. En los sujetos sanos se encontraron con frecuencia elevada P. intermedia/P. nigrescens, C. rectus y Fusobacterium spp y con frecuencia moderada, M. micros y E. corrodens. Conclusión. Los resultados indican que P. gingivalis, T. forsythia, P. intermedia/P. nigrescens, C. rectus, Fusobacterium spp y E. corrodens constituyen parte importante del perfil microbiológico de las periodontitis en la población colombiana. En la periodontitis agresiva, P. gingivalis se encontró más frecuentemente que A. actinomycetemcomitans.Palabras clave: periodontitis/epidemiología, Porphyromonas gingivalis, bacterias anaerobias, Enterobacteriaceae, Pseudomonadaceae.Subgingival microbiota in chronic and aggressive periodontitis in Bogotá, Colombia: an epidemiological approach Introduction. Periodontitis-associated microbiotas differ in regions around the world and vary with a variety of factors. This suggests that each country must establish its own dental microbiobiotic profile in order to formulate adequate prevention measures and more specific treatments. Objective. The prevalence and proportions of the following microorganisms were investigated: Porphyromonas gingivalis, Tannerella forsythia, Actinobacillus actinomycetemcomitans, Prevotella intermedia/Prevotella nigrescens, Eikenella corrodens, Campylobacter rectus, Micromonas micros, Fusobacterium spp, Dialister pneumosintes and enteric rods. The patients selected had been diagnosed with chronic periodontitis and aggressive periodontitis from clinical populations in Bogotá, Colombia. The variables of age, gender and socioeconomic level were included in the comparisons. Materials and methods. 183 patients were classified in two groups, chronic periodontit...

The Eurobarometer report from December 2019 revealed that 80% of European Union (EU) citizens believe that industry is doing too little to protect the environment and that more work needs to be done to help companies transition to a more sustainable economic model. In recent years, the EU has made the Circular Economy (CE) a priority, and an environmental management system based on the EMAS Regulation can help companies achieve this goal by assisting them in analysing and measuring an efficient and sustainable use of resources. Thus, this study analyses EMAS companies’ environmental statements in order to identify and quantify the CE practices they have implemented. Findings identify 23 circular practices and show that the majority of companies focus their efforts on reducing emissions by optimizing the materials cycle and improving internal production processes. Eco-design stands out as the main driver amongst the circular transformation practices. This study has also detected a lack of uniformity in the way companies quantify the various circular practices currently operating, or how they communicate this information. These results may be useful to companies, professionals and administrations responsible for promoting the CE, and it can also provide guidance on what information to include in future environmental statements.
