Background The Severe Acute Respiratory Syndrome Coronavirus 2 pandemic has exposed surgeons to hazardous working conditions, imposing the need for personal protective equipment (PPE) use during surgery. The use of such equipment may affect their non-technical skills, augment fatigue, and affect performance. This study aimed to assess the surgeons' perceptions of the impact of wearing PPE during emergency surgery throughout the pandemic. Methods An international cooperation group conducted an anonymous online survey among surgeons from over 30 countries, to assess perceptions about the impact of PPE use on non-technical skills, overall comfort, decision making, and surgical performance during emergency surgery on COVID-19 patients.Results Responses to the survey (134) were received from surgeons based on 26 countries. The vast majority (72%) were males. More than half of the respondents (54%) felt that their surgical performance was hampered with PPE. Visual impairment was reported by 63%, whereas 54% had communication impediments. Less than half (48%) felt protected with the use of PPE, and the same proportion perceived that the use of such equipment influenced their decision making. Decreased overall comfort was cited by 66%, and 82% experienced increased surgical fatigue. Conclusions Surgeons perceived impediment for both visibility and communication, and other non-technical skills while using PPE on emergency surgery in COVID-19 patients. Their perceived lack of protection and comfort and increased fatigue may have inhibited their optimal surgical performance. More attention should be placed in the design of more user-friendly equipment, given the possibility of a second wave of the pandemic.

Background: The pyogenic liver abscess has an incidence of 1.1/1,000 habitants. Mortality can reach 100%. The use of less invasive procedures diminish morbidity and hospital stay. Aim: Identify risk factors in patients who underwent percutaneous drainage guided by ultrasound as treatment. Method: Were analyzed 10 patients submitted to the method. Epidemiological characteristics, laboratory markers and imaging exams (ultrasound and CT) were evaluated. Results: The majority of the patients were men with mean age of 50 years old. Liver disease, alcoholism and biliary tract disease were the most common prodromes. Abdominal pain (90%), fever (70%) and jaundice (40%) were the most common clinical manifestations. Mortality of 20% was observed in this series. Hypoalbuminemia and days of hospitalization had a statistically significant positive association with death. Conclusion: The pyogenic liver abscess has subacute evolution which makes the diagnosis difficult. Image exams have high sensitivity in diagnosis, particularly computed tomography. Percutaneous drainage associated with antibiotic therapy is safe and effective therapeutic resource.

Introdução: a pandemia provocada pelo 2019 Novel Coronavírus (COVID-19) provocou um desafio global de saúde pública, com repercussões em diversos setores da sociedade. As práticas médicas necessitaram adaptar-se no atendimento ao doente portador do COVID-19 ou suspeito. Métodos: realizou-se pesquisa bibliográfica de publicações e de diretrizes de sociedades médicas em relação às abordagens cirúrgicas de emergência nesta atual pandemia. Resultados: o material bibliográfico ainda é escasso, indefinido e de baixa evidência, mas são adequados neste momento inicial de enfrentamento do COVID-19 no Brasil. Conclusão: para reduzir o risco de contaminação dos profissionais de saúde, as técnicas e decisões cirúrgicas precisam adaptar-se ao cenário de pandemia do COVID-19.

Global software development projects are passing through the boundaries of a company or a country. In order to manage global teams effectively, it is necessary to define a software process adapted to different organizational cultures. A global software process gives all team members a common language to define tasks and activities allowing the better understanding of the business domain terms and the project milestones in spite of their differences in terms of culture and organizational structures. This paper presents the practices adopted to define a global software process for a distributed environment and the factors that impacted in the process definition. Lessons learned are also presented.

Many methodologies, practices, techniques and tools have been suggested for process improvement, among them knowledge management and agile methodologies, which are the focus of this study. Systematic reviews published on knowledge management and agile methodologies have significantly contributed to detailed and deep discussions surrounding these issues. Nevertheless, we realised that there was a gap between these two areas that needed further clarification. Therefore, the objective of this study was to raise the main topics that emerge from knowledge management in agile methodologies. The research method used in this paper is based on a systematic review. We reviewed studies of knowledge management and agile methodologies, published in major software engineering journals and conference proceedings. The search strategy identified 2879 studies, of which 25 were selected as primary studies. The main topics were taken from these 25 works and, in order for them to be discussed; meta-analysis techniques were used to group these topics. The main discussion generated around these analyses was the preferential use of tacit knowledge, instead of explicit knowledge, and its influence on agile projects. This situation has implications for communication, human and social factors, software development cycle and artifacts, tools for knowledge management and knowledge representation forms.

The coronavirus pandemic led society to adopt measures to contain its spread that generate impacts in the social, economic and psychological spheres, mainly due to social isolation. Some authors point out that social changes have generated changes in the various forms of trauma and violence. For this study, data collection for the years 2019 and 2020 was carried out on DATASUS - TABNET and on the website of the Secretariat of Public Security - SSP, considering various types of trauma and violence, with subsequent correlation analysis using the Kendall coefficient and correlation test. There was statistical significance, allowing a correlation with the negative pandemic for the rates of body injury due to traffic accidents, gunshot injuries, stab wounds, sexual violence, bodily injuries and interpersonal violence. As factors possibly associated with a reduction in the incidence of these variables, the literature presents some changes resulting from the pandemic, such as adherence to isolation, with a reduction in the flow of people on the street, and a decrease in reports of violence. The present study indicates that the findings may serve as a warning for future changes and for the adoption of preventive measures, however they represent the initial situation of the pandemic in São Paulo and, therefore, further investigations must be carried out with the course of the pandemic, which still remains.
