Severe complication by irregular use of industrial silicone in a transsexual patient: a case report

The use of industrial liquid silicone as a material for aesthetic modification of body contour is a practice that has been carried out clandestine for about 60 years. Currently, most reports come from countries in Asia and South America, and the victims are mainly women and transsexuals. Due to the large number of cases with complications, the use of industrial silicone for aesthetic purposes has never been approved. However, it continues to be applied alone or associated with other products, determining severe local and systemic complications. We report a case of death of a transsexual patient after injecting industrial silicone in the thighs and buttocks

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

Sistema para calibração comparativa de transdutores em baixa frequência

3 f. : il.Este artigo apresenta um sistema desenvolvido no Laboratório de Vibrações do Inmetro para a calibração comparativa de transdutores de vibração em baixas frequências. Este sistema é baseado em um excitador eletrodinâmico, um acelerômetro de referência, uma placa de aquisição de dados e um software de automação. O sistema permite a realização de calibrações em conformidade com a norma internacional ISO 16063-21[1] na faixa de frequências entre 1 Hz e 160 Hz.

A new system for primary interferometric calibration of vibration transducers at low frequencies

5 p.: il.This paper presents a primary interferometric calibration system that was developed in the Vibration Laboratory at INMETRO for the calibration of vibration transducers and measuring instruments at low frequencies. This system is based on a long-stroke air bearing shaker, and on a data acquisition board. It has been used for calibration of accelerometers and servo-accelerometers within the frequency range from 0,4 Hz to 160 Hz. Optionally, the system can be adapted to calibrate laser vibrometers for their further use as comparison reference transducers. Fully automated calibrations are carried out in compliance with the international standard ISO 16063-11 employing the fringe counting method. Some experimental results obtained with this system will be presented herein

Biotechnological potential of yeast isolates from cachaça: the brazilian spirit

This study identified phenotypic traits appropriate for biotechnological applications of 118 yeasts isolated from cachaça distilleries. Different properties were verified: capacity to use alternative carbon sources; ability to tolerate high concentrations of sucrose, ethanol, methanol, aluminum and zinc as well as different pH values and foam production. Pichia guilliermondii and Pichia anomala strains were identified as the most promising ones for application in the second-generation biofuel industry, showing ability to grow on high glycerol concentrations. Other isolates, identified as Saccharomyces cerevisiae, produced bioethanol comparable to the industrial strains, and were therefore ideal for use in the first-generation ethanol industry. Some of these strains also showed high resistance to aluminum, as observed in sugarcane juice, and to inter-cycle washings with diluted sulphuric acid, as performed in the industrial bioethanol production process. In summary, yeast isolates from cachaça distilleries displayed robustness and phenotypic plasticity, which makes them interesting for biotechnological applications.This work was supported by grants from Fundação de Capacitação de Pessoal de Nível Superior from the Ministry of Education, CAPES/Brazil (PNPD 2755/2011; PCF-PVE 021/2012) and from Universidade Federal de Ouro Preto, Fundação de Amparo à Pesquisa do Estado de Minas Gerais, FAPEMIG (Process APQ-00263-10) and a research fellowship from Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq (Brazil) Process 304815/2012.

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
