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

Herniorrafia inguinal com anestesia local em regime ambulatorial

OBJETIVO: Comprovar a viabilidade da técnica de herniorrafia inguinal com anestesia local, em regime ambulatorial, com segurança, eficácia e curta curva de aprendizado. MÉTODOS: Analisamos prospectivamente 454 pacientes submetidos à herniorrafias inguinais sob anestesia local em regime ambulatorial entre novembro de 2004 e agosto de 2008. Do total de hérnias tratadas cirurgicamente neste período, 285 foram operadas à direita, 163 à esquerda e seis bilaterais. Foram utilizados critérios clínicos, cirúrgicos e psicossociais para inclusão no procedimento. Os parâmetros para exclusão foram hérnia complexa ou irredutível, hérnia recidivada, obesidade (IMC maior que 30 Kg/m²), recusa do paciente e pacientes psiquiátricos. Todos os pacientes foram operados eletivamente e analisados quanto ao resultado cirúrgico, suas complicações e tempo de internação hospitalar. RESULTADOS: Todas as operações foram concluídas com êxito. Em nenhum dos casos foi necessário a mudança do método anestésico. O tempo cirúrgico foi semelhante ao realizado com outros métodos de anestesia, não havendo casos de efeitos adversos dos anestésicos locais. As complicações intra-operatórias totalizaram aproximadamente 2,64% (12/454) dos casos. Não houve necessidade de internações hospitalares superiores ao período de 24 horas. CONCLUSÃO: O procedimento é viável sem dor per - operatória significativa, com segurança, podendo ser realizada por residentes sob supervisão, com satisfatória aceitação pelos pacientes, com complicações semelhantes às observadas em uma herniorrafia convencional, possibilitando um tempo e custo de internação menor e acesso mais rápido dos pacientes ao tratamento

A voz do Brasil: Miguel Pereira e o discurso sobre o "imenso hospital" The voice of Brazil: Miguel Pereira and his speech on the "enormous hospital"

Este trabalho reproduz e comenta importante fonte primária muito citada nos estudos em história da saúde no Brasil, mas pouco conhecida em sua integralidade. Trata-se do discurso do médico Miguel Pereira, proferido em outubro de 1916, e no qual se referiu à zona rural do país como 'um imenso hospital'. A interpretação consagrada dessa fonte é a de que sua repercussão teve persistente e decisiva influência em políticas públicas de saúde na primeira metade do século XX. Neste texto, aprofundo o conhecimento das circunstâncias históricas que geraram a elaboração dessa expressão-síntese dos 'males do Brasil', sobretudo no que se refere às discussões, então em curso, a respeito do recrutamento militar obrigatório e do Exército como 'escola de civismo'.<br>The article reproduces and comments on an important primary source that is often cited in studies on Brazil's history of health but which few are familiar with in its entirety: the October 1916 speech by physician Miguel Pereira, in which he referred to rural Brazil as an "enormous hospital." The standard interpretation is that this source had a steady, decisive influence on public health policies in the first half of the twentieth century. In this text, I endeavor to deepen our knowledge of the historical circumstances which produced this expression that synthesized the 'evils of Brazil', especially in regard to the era's discussion of mandatory military recruitment and of the army as a 'civics school'

A Transcript Finishing Initiative for Closing Gaps in the Human Transcriptome

We report the results of a transcript finishing initiative, undertaken for the purpose of identifying and characterizing novel human transcripts, in which RT-PCR was used to bridge gaps between paired EST clusters, mapped against the genomic sequence. Each pair of EST clusters selected for experimental validation was designated a transcript finishing unit (TFU). A total of 489 TFUs were selected for validation, and an overall efficiency of 43.1% was achieved. We generated a total of 59,975 bp of transcribed sequences organized into 432 exons, contributing to the definition of the structure of 211 human transcripts. The structure of several transcripts reported here was confirmed during the course of this project, through the generation of their corresponding full-length cDNA sequences. Nevertheless, for 21% of the validated TFUs, a full-length cDNA sequence is not yet available in public databases, and the structure of 69.2% of these TFUs was not correctly predicted by computer programs. The TF strategy provides a significant contribution to the definition of the complete catalog of human genes and transcripts, because it appears to be particularly useful for identification of low abundance transcripts expressed in a restricted set of tissues as well as for the delineation of gene boundaries and alternatively spliced isoforms

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2

The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios
