Quality of emergency oncological surgery: time for advanced oncological life support.

OBJECTIVE: In the emergency care of cancer patients, in addition to cancer-related factors, two aspects influence the outcome: (1) where the patient is treated and (2) who will perform the surgery. In Brazil, a significant proportion of patients with surgical oncological emergencies will be operated on in general hospitals by surgeons without training in oncological surgery. OBJECTIVE: The objective was to discuss quality indicators and propose the creation of an urgent oncological surgery advanced life support course. METHODS: Review of articles on the topic. RESULTS: Generally, nonelective resections are associated with higher rates of morbidity and mortality, as well as lower rates of cancer-specific survival. In comparison to elective procedures, the reduced number of harvested lymph nodes and the higher rate of positive margins suggest a compromised degree of radicality in the emergency scenario. CONCLUSION: Among modifiable factors is the training of the emergency surgeon. Enhancing the practice of oncological surgery in emergency settings constitutes a formidable undertaking that entails collaboration across various medical specialties and warrants endorsement and support from medical societies and educational institutions. It is time to establish a national registry encompassing oncological emergencies, develop quality indicators tailored to the national context, and foster the establishment of specialized training programs aimed at enhancing the proficiency of physicians serving in emergency services catering to cancer patients.

Influence of the COVID-19 pandemic on the epidemiological profile of the initial care of victims of falls.

OBJECTIVE: to assess the epidemiological profile of trauma patients from fall from the same level (FSL) and fall from an elevated level (FEL) during the COVID-19 pandemic, and to compare it with data from different levels of restriction (flags) and data prior to the pandemic. METHOD: a cross-sectional study with a probability sample of the medical records of patients aged 18 years or older admitted to the emergency room due to falls, from June 2020 to May 2021. Epidemiological data, such as sex, age and injuries were analyzed, as well the current level of restriction. The three restriction periods were compared between then and the proportion of admissions due to falls was compared with the period from December 2016 to February 2018. RESULTS: a total of 296 admissions were evaluated, 69.9% were victims of FSL and 30.1% of FEL. The mean age was 57.6 years, and 45.6% were over 60 years old. Admissions among men predominated, and 40.2% of patients required hospitalization. During the red flag period, there were proportionally more injuries to the head and neck (p=0.016), injuries to extremities (p=0.015) and neurological trauma (p<0.001). An average of 6.1, 6.3 and 5.2 admissions per day was obtained during the yellow, orange and red flag, respectively. There was a relative increase in falls when compared to the pre-pandemic period. CONCLUSIONS: there was an absolute reduction in admissions of victims of falls in midst of the most restrictive period during the pandemic. However, when compared to pre-pandemic data, there was a relative increase in falls.

RESUMO Objetivo: avaliar o perfil epidemiológico do trauma por quedas de mesmo nível (QMN) e quedas de nível elevado (QNE) durante a pandemia da COVID-19, realizar a comparação dos dados entre os níveis de restrição (bandeiras) e comparar com dados prévios à pandemia. Método: estudo transversal com amostragem probabilística de prontuários de pacientes com 18 anos ou mais admitidos na sala de emergência devido a quedas de junho de 2020 a maio de 2021. Foram avaliados dados epidemiológicos, como sexo, idade e lesões resultantes, além da bandeira vigente. Os três períodos de restrição foram comparados entre si e a proporção de atendimentos por quedas foi comparada com o período de dezembro de 2016 a fevereiro de 2018. Resultados: avaliou-se 296 atendimentos, sendo 69,9% vítimas de QMN e 30,1% de QNE. A média de idade foi 57,6 anos, sendo que 45,6% apresentavam idade superior a 60 anos. Sexo masculino predominou e 40,2% dos pacientes necessitaram internamento hospitalar. Durante a bandeira vermelha proporcionalmente ocorreram mais lesões em cabeça e pescoço (p=0,016), trauma em extremidades (p=0,015) e neurológico (p<0,001). Obteve-se uma média de 6,1, 6,3 e 5,2 atendimentos/dia durante a bandeira amarela, laranja e vermelha respectivamente. Ocorreu um aumento significativo da ocorrência de quedas quando comparado ao período prévio à pandemia. Conclusões: durante o período pandêmico, verificou-se uma redução absoluta de atendimentos de vítimas de quedas na bandeira mais restritiva. Porém, quando comparado ao período pré-pandêmico, verifica-se um aumento significativo das quedas.

Impact of the COVID-19 pandemic on the epidemiology of traffic accidents: a cross-sectional study.

OBJECTIVE: to assess the epidemiological profile of traffic accident victims in the setting of the Coronavirus Disease 2019 (COVID-19) pandemic and analyze the admissions throughout the different levels of restriction (flags), as well as compare the results with the pre-pandemic period. METHODS: a cross-sectional study was performed, with probability sampling, in a trauma center in Brazil. Medical records of patients involved in traffic accidents from June 2020 to May 2021 were evaluated. Aside from epidemiological characteristics, variables such as the current flag, the trauma mechanism, the resulting injuries, and the Revised Trauma Score (RTS) were also considered. Data were compared between three different flag periods and the proportion of consultations during the pandemic was compared with that from pre-pandemic time (December 2016 to February 2018). RESULTS: it was observed that 62.2% of the patients were victims of motorcycle accidents, 77.5% were male, and the mean age was 33 ± 12.4 years. The mean and median RTS were 7.5 and 7.8, respectively. Statistical difference was stated when comparing the number of visits per day between the yellow and red flags (p=0.001) and orange and red flags (p=0.016). A significantly lower number of consultations for traffic accidents was observed in the pandemic when compared to the pre-pandemic period. CONCLUSIONS: the epidemiological profile of the study consisted mostly of young men who were victims of motorcycle accidents. There was a lower incidence of admissions during red flag periods and a lower proportion of consultations throughout the survey when compared to the pre-pandemic period.

RESUMO Introdução: avaliar o perfil epidemiológico das vítimas de acidentes de trânsito no contexto da pandemia da doença do coronavírus 2019 (COVID-19), analisar os atendimentos entre os níveis de restrição implementados (bandeiras) e comparar os dados com o período pré-pandêmico. Métodos: trata-se de um estudo transversal, com amostragem probabilística, realizado em um hospital de trauma no sul do Brasil utilizando prontuários de pacientes vítimas de acidente de trânsito entre junho de 2020 a maio de 2021. Além das variáveis epidemiológicas, coletou-se a bandeira vigente, o mecanismo de trauma, as lesões resultantes e o Revised Trauma Score (RTS). Os dados foram comparados entre as três bandeiras e a proporção de atendimentos do período pandêmico foi comparada com a do período pré-pandêmico (dezembro de 2016 a fevereiro de 2018). Resultados: observou-se que 62,2% dos pacientes foram vítimas de acidentes com motocicletas, 77,5% da amostra era do sexo masculino e que a média etária foi de 33 ± 12,4 anos. A média e mediana do RTS foram 7,5 e 7,8, respectivamente. Houve diferença significativa ao comparar o número de atendimentos ao dia entre as bandeiras amarela e vermelha (p=0,001) e laranja e vermelha (p=0,016). Constatou-se um número significativamente menor de atendimentos por acidentes de trânsito no período pandêmico quando comparado com o período pré-pandêmico. Conclusões: o perfil epidemiológico do estudo foi composto em sua maioria por homens jovens vítimas de acidentes com motocicleta. Houve menor incidência de admissões na bandeira vermelha e menor proporção de atendimentos no período da pesquisa quando comparado ao pré-pandêmico.

Trauma in Curitiba: multifactorial assessment of victims admitted to a university hospital. / Trauma em Curitiba: avaliação multifatorial de vítimas admitidas em um hospital universitário.

OBJECTIVE: to describe the epidemiological profile of trauma patients admitted to a referral hospital in Curitiba (PR). Also, to investigate trauma mechanisms and to evaluate trauma severity scores. METHODS: descriptive observational cross-sectional study. Data were collected by applying a questionnaire to victims admitted in the emergency room from December 2016 to February 2018. RESULTS: a total of 1354 trauma victims were included in the study, of which 60% were transported by SIATE and 40% by SAMU. Regarding gender, 70% of the patients were male. The mean age was 39.48 years. About the time and day of the calls, the largest proportion was concentrated on Friday night. In relation to the mechanism of trauma, in patients transported by SIATE, the most frequent in men was motorcycle collision (34.3%), while in women was same-level fall (21.42%). In SAMU, the most frequent mechanism regardless of gender was same-level fall (20.06% and 40.66%, respectively). Analyzing the severity scores, it was observed that 95.5% of the patients were classified as mild by the Glasgow Coma Scale. CONCLUSION: the profile of trauma victims analyzed in this large study is quite similar to what other national smaller studies have already described: young men victims of traffic accidents. Therefore, the economically active population is the most affected, reflecting in high cost to society.

OBJETIVO: descrever o perfil epidemiológico das vítimas de trauma atendidas em um hospital de referência no município de Curitiba (PR), bem como investigar os mecanismos do trauma, além de avaliar os escores de gravidade. MÉTODOS: estudo descritivo observacional transversal, cujos dados foram obtidos através da aplicação de questionário em vítimas atendidas na sala de emergência, entre dezembro de 2016 e fevereiro de 2018. RESULTADOS: foram incluídos no estudo 1354 vítimas de trauma, das quais 60% tiveram como transporte pré-hospitalar o Serviço Integrado de Atendimento ao Trauma em Emergência (SIATE), e 40%, o Serviço de Atendimento Móvel de Urgência (SAMU). Quanto ao sexo, 70% dos pacientes eram do sexo masculino. A média de idade foi de 39,48 anos. Sobre o horário e dia dos atendimentos, a maior proporção se concentrou no período noturno na sexta-feira. Quanto ao mecanismo do trauma, nos pacientes atendidos pelo SIATE, o mais frequente em homens foi a colisão de motocicleta (34,3%), enquanto que em mulheres foi a queda de mesmo nível (21,42%). Já no SAMU, o mecanismo mais frequente independentemente do sexo foi queda de mesmo nível (20,06% e 40,66%, respectivamente). Analisando-se os escores de gravidade, observou-se que 95,5% dos pacientes eram classificados como leves pela escala de coma de Glasgow. CONCLUSÕES: o perfil das vítimas analisadas neste grande estudo muito se assemelha a outros estudos nacionais menores: homens, jovens, vítimas de acidentes de trânsito. A população economicamente ativa, portanto, é a mais afetada, refletindo em alto custo para a sociedade.

The recommendations of the Brazilian College of Surgeons and the Brazilian Bariatric and Metabolic Surgery Societies on the return of bariatric and metabolic operations in geographic regions of the country where the procedures have been allowed by local policies, in the period of COVID-19 pandemic.

Prioritizing surgical procedures aims at facilitating patient's access according to the clinical needs, maximizing access equity, and minimizing the damage from delayed access. Previous categorization of elective bariatric surgery have been adapted to define an objective prioritizing system that reflects those principles for bariatric and metabolic operations. Given the factors that contribute to the morbidity and mortality of obese and type 2 diabetes patients, surgical prioritization should be based on clinical risk stratification. For patients with type 2 diabetes, we suggest that the operation may be prioritized for those with a higher risk of morbidity and mortality in a relatively short term. Likewise, it is necessary to guide the surgical team regarding the necessary care both in the pre, per and postoperative periods of bariatric and metabolic surgery. These recommendations aim to reduce the risk of in-hospital contamination of the surgical team among health professionals and between health professionals and patients. In summary, these recommendations have been shaped after a thorough analysis of the available literature and are extremely important to mitigate the harm related to the clinical complications of obesity and its comorbidities while keeping healthcare providers' and patients' safety.

Elective surgeries in the "new normal" post-COVID-19 pandemic: to test or do not test?

The new coronavirus (SARS-CoV-2) pandemic has been wreaking havoc all over the planet. In a precautionary measure, populations have been forced and kept under quarantine to contain the outbreak of the COVID-19 disease. The quarantine primary goal is to avoid the overload to the hospitals, which should be available for the care of COVID-19 patients. However, the virus does not have a uniform spread throughout the planet, and Brazil is no different. Although all the world's attention is now on the COVID-19 pandemic, there is no similar pattern of spread, and other diseases are still a real problem. Given the risks of transmission between patients and healthcare providers, there is a great challenge for healthcare institutions who must balance resources to assure safe care to patients and professionals while they take care of other disease patients, and perform surgical procedures that need to be carried out. Under such circumstances, as COVID-19 can also present pre- or asymptomatic transmission, it can be challenging to identify patients who are carrying and spreading the virus. Studies and information on mandatory testing for who are candidates to undergo elective surgery are scarce. Thus, the authors have reviewed the literature, and discuss the need to test these patients under the current context.

RESUMO A pandemia do novo coronavírus (SARS-CoV-2) vem causando estragos em todo o planeta. As populações estão sendo forçadas a quarentena - e assim mantidas - como medida de precaução para conter o surto da doença COVID-19. O principal objetivo da quarentena é evitar a sobrecarga dos hospitais, o que pode ser determinante para o atendimento aos pacientes COVID-19. O vírus não tem propagação uniforme pelo planeta, e no Brasil não é diferente. Contudo, as pessoas continuam a adoecer por outras causas não relacionadas ao SARS-CoV-2, demandando atendimento médico-hospitalar. Assim, os governos estão avaliando e liberando regiões para a realização de cirurgias eletivas em Estados e Municípios onde a COVID-19 está sob controle. Nesse contexto, há preocupação inerente à transmissão SARS-CoV-2 entre pacientes e prestadores de serviços de saúde, uma vez que há poucas informações sobre testes obrigatórios a serem realizados em pacientes com indicação cirúrgica. Esse problema é causado principalmente porque todos os pacientes durante o período de incubação são assintomáticos e, portanto, difíceis de serem avaliados. Assim sendo, os autores avaliam a literatura pertinente à microbiologia do SARS-CoV-2 e discutem a necessidade de testar esses pacientes com testes mais utilizados até o momento.

RESUMO A priorização de qualquer operação eletiva visa facilitar o acesso do paciente de acordo com as necessidades clínicas, maximizando a equidade de acesso e minimizando os danos causados pelo atraso. As categorias de operações eletivas foram adaptadas para definir sistema de priorização objetiva que reflete esses princípios para operações bariátricas e metabólicas. Em razão dos fatores que contribuem para a morbidade e mortalidade da obesidade e do diabetes tipo 2, a priorização cirúrgica deve ser baseada na estratificação de risco clínico. Para pacientes com diabetes tipo 2, sugerimos que a operação possa ser priorizada para aqueles com maior risco de morbidade e mortalidade, em prazo relativamente curto. Da mesma forma, é necessário orientar a equipe cirúrgica quanto aos cuidados necessários tanto no pré, per e pós-operatório da cirurgia bariátrica e metabólica. As recomendações visam reduzir o risco de contágio hospitalar da equipe cirúrgica tanto entre profissionais de saúde quanto entre profissionais de saúde e pacientes. Em resumo, estas recomendações foram moldadas após análise minuciosa da literatura disponível e são extremamente importantes para mitigar os danos das complicações clínicas, sensíveis a doença obesidade e comorbidades, mantendo a segurança dos profissionais de saúde e dos pacientes.

Analysis of the Revised Trauma Score (RTS) in 200 victims of different trauma mechanisms.

OBJECTIVE:: to analyze the epidemiological profile and mortality associated with the Revised Trauma Score (RTS) in trauma victims treated at a university hospital. METHODS:: we conducted a descriptive, cross-sectional study of trauma protocols (prospectively collected) from December 2013 to February 2014, including trauma victims admitted in the emergency room of the Cajuru University Hospital. We set up three groups: (G1) penetrating trauma to the abdomen and chest, (G2) blunt trauma to the abdomen and chest, and (G3) traumatic brain injury. The variables we analyzed were: gender, age, day of week, mechanism of injury, type of transportation, RTS, hospitalization time and mortality. RESULTS:: we analyzed 200 patients, with a mean age of 36.42 ± 17.63 years, and 73.5% were male. The mean age was significantly lower in G1 than in the other groups (p <0.001). Most (40%) of the visits occurred on weekends and the most common pre-hospital transport service (58%) was the SIATE (Emergency Trauma Care Integrated Service). The hospital stay was significantly higher in G1 compared with the other groups (p <0.01). Regarding mortality, there were 12%, 1.35% and 3.95% of deaths in G1, G2 and G3, respectively. The median RTS among the deaths was 5.49, 7.84 and 1.16, respectively, for the three groups. CONCLUSION:: the majority of patients were young men. RTS was effective in predicting mortality in traumatic brain injury, however failing to predict it in patients suffering from blunt and penetrating trauma. OBJETIVO:: analisar o perfil epidemiológico e a mortalidade associada ao escore de trauma revisado (RTS) em vítimas de trauma atendidas em um hospital universitário. MÉTODOS:: estudo transversal descritivo de protocolos de trauma (coletados prospectivamente) de dezembro de 2013 a fevereiro de 2014, incluindo vítimas de trauma admitidas na sala de emergência do Hospital Universitário Cajuru. Três grupos foram criados: (G1) trauma penetrante em abdome e tórax, (G2) trauma contuso em abdome e tórax, e (G3) trauma cranioencefálico. As variáveis analisadas foram: sexo, idade, dia da semana, mecanismo de trauma, tipo de transporte, RTS, tempo de internamento e mortalidade. RESULTADOS:: analisou-se 200 pacientes, com média de idade de 36,42 ± 17,63 anos, sendo 73,5% do sexo masculino. A média de idade no G1 foi significativamente menor do que nos demais grupos (p <0,001). A maioria (40%) dos atendimentos ocorreu nos finais de semana e o serviço de transporte pré-hospitalar mais frequente (58%) foi o SIATE (Serviço Integrado de Atendimento ao Trauma em Emergência). O tempo de internamento foi significativamente maior no G1, em comparação aos demais grupos (p <0,01). Quanto à mortalidade, houve 12%, 1,35% e 3,95% de óbitos nos grupos G1, G2 e G3, respectivamente. A mediana do RTS entre os óbitos foi 5,49, 7,84 e 1,16, respectivamente, para os três grupos. CONCLUSÃO:: a maioria dos pacientes eram homens jovens. O RTS mostrou-se efetivo na predição de mortalidade no trauma cranioencefálico, entretanto falhou ao analisar pacientes vítimas de trauma contuso e penetrante.

O tempo de internamento foi significativamente maior no G1, em comparação aos demais grupos (p <0,01). Quanto à mortalidade, houve 12%, 1,35% e 3,95% de óbitos nos grupos G1, G2 e G3, respectivamente. A mediana do RTS entre os óbitos foi 5,49, 7,84 e 1,16, respectivamente, para os três grupos. Conclusão: a maioria dos pacientes eram homens jovens. O RTS mostrou-se efetivo na predição de mortalidade no trauma cranioencefálico, entretanto falhou ao analisar pacientes vítimas de trauma contuso e penetrante.

Effects of low intensity laser in in vitro bacterial culture and in vivo infected wounds.

OBJECTIVE: to compare the effects of low intensity laser therapy on in vitro bacterial growth and in vivo in infected wounds, and to analyze the effectiveness of the AsGa Laser technology in in vivo wound infections. METHODS: in vitro: Staphylococcus aureus were incubated on blood agar plates, half of them being irradiated with 904 nm wavelength laser and dose of 3J/cm² daily for seven days. In vivo: 32 male Wistar rats were divided into control group (uninfected) and Experimental Group (Infected). Half of the animals had their wounds irradiated. RESULTS: in vitro: there was no statistically significant variation between the experimental groups as for the source plates and the derived ones (p>0.05). In vivo: there was a significant increase in the deposition of type I and III collagen in the wounds of the infected and irradiated animals when assessed on the fourth day of the experiment (p=0.034). CONCLUSION: low-intensity Laser Therapy applied with a wavelength of 904 nm and dose 3J/cm² did not alter the in vitro growth of S. aureus in experimental groups; in vivo, however, it showed significant increase in the deposition of type I and III collagen in the wound of infected and irradiated animals on the fourth day of the experiment.

OBJETIVO: comparar os efeitos da terapia a laser de baixa intensidade no crescimento bacteriano in vitro e em feridas infectadas in vivo, e analisar a efetividade da tecnologia Laser AsGa, em feridas infectadas in vivo. MÉTODOS: in vitro: cepas de Staphylococcus aureus foram incubadas em placas de agar-sangue e irradiadas com laser de 904nm de comprimento de onda e dose de 3J/cm2, diariamente durante sete dias. In vivo: 32 ratos machos Wistar foram distribuídos em Grupo Controle (Não Infectado) e Grupo Experimental (Infectados). Metade dos ratos tiveram suas feridas irradiadas e a outra metade não irradiada, como realizado no estudo in vitro. RESULTADOS: in vitro: não houve variação estatística significativa entre os grupos experimentais, considerando as placas matrizes e derivadas (p>0,05). In vivo: houve aumento significativo na deposição de colágeno tipo I e III na cicatriz do grupo dos animais infectados e irradiados, quando avaliados no quarto dia de experimento (p=0,034). CONCLUSÃO: a Low-Intensity Laser Therapy aplicada com comprimento de onda de 904nm e dose de 3J/cm2, in vitro: não alterou o crescimento de S. aureus nos grupos experimentais. In vivo: mostrou aumento significativo na deposição de colágeno tipo I e III na cicatriz no grupo dos animais infectados e irradiados no quarto dia de experimento. .

Short-term effect of gastric bypass in obese diabetic patients.

OBJECTIVE: To study the effect of gastric bypass on blood glucose levels and the use of antidiabetic medication in obese patients with diabetes. METHODS: We carried out a retrospective cohort study with 44 obese patients with DM2, from 469 patients undergoing gastric bypass from December 2001 to March 2009. The primary endpoints evaluated were fasting glucose and the need for antidiabetic medication. RESULTS: The study population consisted of ten (22.7%) men and 34 (77.3%) women, with a mean age of 45.3 (±8.23) years and a body mass index of 40.9 (±5.03) kg/m². The average time to progression of DM2 was 63.6 (±60.9) months. Of the 40 patients who used medication to control type 2 diabetes, 20 (50%) had their medication discontinued at discharge and 13 (32.5%), until nine months later. In one patient it was not possible to evaluate the use of medication, this being the only exception. Insulin was suspended in ten (100%) patients who used it, six (60%) at discharge. Fasting plasma glucose levels decreased throughout the study period (p <0.05) when compared with preoperative values, and values below 100mg/dl were achieved within seven to nine months. CONCLUSION: Obese patients with DM2 undergoing gastric bypass showed improved glycemic control and reduced use of hypoglycemic agents in the short-term.

O efeito em curto prazo do bypass gástrico sobre pacientes obesos diabéticos / Short-term effect of gastric bypass in obese diabetic patients

OBJETIVO: estudar o efeito do bypass gástrico sobre a glicemia e o uso de medicação antidiabética em pacientes obesos portadores de diabetes. MÉTODOS: estudo de coorte retrospectivo com 44 pacientes obesos portadores de DM2, provenientes de 469 pacientes submetidos ao bypass gástrico no período de dezembro de 2001 a março de 2009. Os desfechos primários avaliados foram: glicemia em jejum e a necessidade de medicação antidiabética. RESULTADOS: a população foi composta de dez (22,7%) homens e 34 (77,3%) mulheres, com média de idade de 45,3 (±8,23) anos e índice de massa corporal de 40,9 (±5,03) kg/m². O tempo médio de evolução do DM2 foi 63,6 (±60,9) meses. Dos 40 pacientes que utilizavam medicação para controle do DM2, 20 (50%) tiveram sua medicação suspensa na alta hospitalar e 13 (32,5%) até nove meses depois. Em uma paciente não foi possível avaliar o uso de medicação, sendo essa a única exclusão. A insulina foi suspensa nos dez (100%) pacientes que a utilizavam, sendo seis (60%) na alta hospitalar. Houve redução (P<0,05) da glicemia em jejum, em todo o período estudado, em comparação com o valor pré-operatório, e foram atingidos valores inferiores a 100mg/dl no período de sete a nove meses. CONCLUSÃO: Pacientes obesos portadores de DM2, submetidos ao bypass gástrico, apresentaram melhora do controle glicêmico e redução do uso de hipoglicemiantes em curto prazo.
