Infecção natural pelo Trypanosoma cruzi em cães de áreas endêmicas da República Argentina

The population dynamics and the prevalence of chagasic infection of 352 dogs living in 108 rural houses infested by triatomines were studied. The region was divided into three sections according to increasing distances to an urban area. Each animal was identified by means of its particular characteristics and built, and its owners gave information about its habits. By means of xenodiagnosis, serology and ECG studies, prevalences of infection, parasitological-serological correlation, percentage of altered electrocardiographic outlines and percentage of houses with parasitemic dogs, were determined. The rural area showed a characteristic T. cruzi infection pattern and differences in the canine population parameters with respect to the other areas were observed: a higher proportion of puppies than adult dogs, a more sedentary population, higher prevalences of infection, as measured by xenodiagnosis, in dogs, and the highest proportion of bedroom insects infected with T. cruzi. It is assumed that the sedentary characteristics of the human population in that rural area impinge in the blood offer to the triatomine population, and the high percentage of parasitemic dogs of the area, contribute to the rise of "kissing ougs" infected with T. cruzi found in bedrooms.Estudou-se a dinâmica populacional e a prevalência de infecção chagásica de 352 cães vivendo em 108 moradias rurais infestadas por triato-míneos. A área foi dividida em três setores de acordo com suas crescentes distâncias em relação a um povoado urbano. Cada animal foi identificado mediante suas características particulares, e seus donos deram informações a respeito de seus hábitos. As prevalências de infecção foram determinadas por sorologia, correlação parasitológica-sorológica, percentual de traçados eletrocardiográficos alterados e o percentual de moradias com cães parasitados. A área rural mostrou um padrão característico de infecção por T. cruzi e observaram-se diferenças nos parâmetros de população canina em relação às restantes áreas: maior proporção de filhotes, maior população humana e canina sedentárias, maiores prevalências de infecção por xenodiagnóstico em cães e maior proporção de barbeiros infectados com T. cruzi nos cômodos da casa. Supõe-se que as características sedentárias da população humana desta área rural é fundamental para a oferta de sangue para as populações triatomíneas, e a elevada porcentagem de cães parasitêmicos dessa área contribui para o aumento de barbeiros infectados com T. cruzi encontrados nos quartos de dormir

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

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
