Abstract: This research is linked to the research line of Education, Health, and Nursing Policies and Practices and to the umbrella project entitled "Multiprofessional Clinical Simulation: Creation and Validation of Models, Scenarios, and Assessment Instruments". The research was developed through the evaluation of debriefing in the simulated clinical scenario with multiple victims in the hospital environment with undergraduate nursing students, whose objective was to analyze the contribution of debriefing in learning the simulated scenario of care to multiple victims with undergraduate nursing students. The method used was quantitative with a descriptive and transversal design. The results highlight in the characterization of the participants' profile that most of them are female and aged 20-30 years. In the evaluation of the debriefing scales: Debriefing Experience Scale: it is highlighted in the agreement that the debriefing helped to analyze their thoughts; helped to make connections in learning; teacher will allow enough time to verbalize feelings before comments; that they had enough time to clarify the questions and that the teacher made a constructive evaluation of the simulation during the debriefing. In relation to the Rating scale of the debriefing associated to the simulation: it was evident that most undergraduate students agreed that the debriefing identified difficulties in the performance; that it focused on important aspects of the performance; that it reflected my skills; that it identified aspects that should be improved in future performances, and disagreed on not wanting to participate in any further simulation; on feeling disrespected, and on feeling that it was a waste of time. We conclude that the contribution from the results of the evaluation scales is important for the performance of future Nurses through good Nursing practices according to patient safety standards. The relevance of the contribution of the debriefing verified from the results of the evaluation scales is important for the development of technical and communicative skills, and care competencies in an interdisciplinary way. The innovative character of the research: use of active methodologies through clinical simulation. The replicability and social impact of the topic of multiple victim assistance in the hospital setting can be applied in new training courses through clinical simulation with undergraduate students and health professionals, so that they can obtain knowledge about care in mass care with fire and how to proceed in these eventualities.

Lessons from the Fallen: An After-Action Review of Prehospital Casualty Data during the Global War on Terror.

BACKGROUND: The US military's recent involvement in long standing conflict has caused the pioneering of many lifesaving medical advances, often made possible by data-driven research. However, future advances in battlefield medicine will likely require greater data fidelity than is currently attainable. Continuing to improve survival rates will require data which establishes the relative contributions to preventable mortality and guides future interventions. Prehospital data, particularly that from Tactical Combat Casualty Care (TCCC) Cards and TCCC After Action Reports (TCCC AARs), are notoriously inconsistent in reaching searchable databases for formal evaluation. While the military has begun incorporating more modern technology in advanced data capture over the past few years like the Air Force's Battlefield Assisted Trauma Distributed Observation Kit (BATDOK) and the Army's Medical Hands-free Unified Broadcast system (MEDHUB), more analysis weighing the advantages and disadvantages of substituting analog solutions is needed. DISCUSSION: We propose 3 changes which may aid prehospital data capture and facilitate analysis: reexamine the current format of TCCC Cards and consider reducing the number of available datapoints to streamline completion, implement a military-wide mandate for all Role 1 providers to complete a TCCC AAR within 24 hours of a casualty event, and formalize the process of requesting de-identified data from the Armed Forces Medical Examiner System (AFMES) database. CONCLUSION: Reflecting on the state of US military medicine after 20 years of war, an important focus is improving the way prehospital data is gathered and analyzed by the military. There are steps we can take now to enhance our capabilities.

An Innovative Civilian Research Model to Inform Combat-Relevant Prolonged Casualty Care.

Prolonged Casualty Care (PCC) is a major US military research focus area. PCC is defined as the need to provide patient care for extended periods when evacuation or mission requirements surpass capabilities and/or capacity. US military experts have called for more data relevant to PCC. In response, we aimed to develop an innovative research model using a tiered system of trauma care in the Western Cape of South Africa as a framework for studying relevant US military trauma care and outcomes in a natural prolonged care environment. The objective of this report is to describe the research model and to illustrate how various components of the model may be helpful to provide data relevant to US military PCC. To develop the model, we used a combination of published data, open access reports, and expert opinion to identify, define, and compare relevant components of the Western Cape trauma system suitable for researching aspects of US military PCC. Several key features of the research model are as follows: In the Western Cape, patients are referred from primary and secondary to tertiary facilities (analogous to escalating capabilities by advancing roles of care in the US military). Western Cape civilian trauma providers' capabilities range from prehospital basic life support to definitive trauma surgical and critical care (comparable to US military Tactical Combat Casualty Care to advanced definitive surgical care). Patterns of injuries (e.g., high rates of penetrating trauma and hemorrhagic shock) and prolonged times from injury to definitive surgical care in the Western Cape system have relevance to the US military. This civilian research model for studying PCC is promising and can inform US military research. Importantly, this model also fills gaps in the South African civilian system and is useful for other prolonged trauma care communities worldwide.

Mass Casualty Incident Management for Resource-Limited Settings: Lessons From Central Haiti.

OBJECTIVE: Mass casualty incidents (MCIs) have gained increasing attention in recent years due multiple high-profile events. MCI preparedness improves the outcomes of trauma victims, both in the hospital and prehospital settings. Yet most MCI protocols are designed for high-income countries, even though the burden of mass casualty incidents is greater in low-resource settings. RESULTS: Hôpital Universitaire de Mirebalais (HUM), a 300-bed academic teaching hospital in central Haiti, developed MCI protocols in an iterative process after a large MCI in 2014. Frequent MCIs from road traffic collisions allowed protocol refinement over time. HUM's protocols outline communication plans, triage, schematics for reorganization of the emergency department, clear delineation of human resources, patient identification systems, supply chain solutions, and security measures for MCIs. Given limited resources, protocol components are all low-cost or cost-neutral. Unique adaptations include the use of 1) social messaging for communication, 2) mass casualty carts for rapid deployment of supplies, and 3) stickers for patient identification, templated orders, and communication between providers. CONCLUSION: These low-cost solutions facilitate a systematic response to MCIs in a resource-limited environment and help providers focus on patient care. These interventions were well received by staff and are a potential model for other hospitals in similar settings.

Children's Health Care in Mass-Casualty Incidents: A Systematic Literature Review.

OBJECTIVES: Considering the pediatric peculiarities and the difficulty of assisting this population in mass-casualty situations, this study aims to identify the main topics regarding children's health care in mass-casualty incidents (MCIs) that are discussed in the Emergency Medicine area. METHODS: This systematic review was performed according to the recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and registered with the PROSPERO database of systematic reviews with the number CRD42021229552. The last update of the search in the databases was on May 27, 2021 and resulted in 45 documents to be analyzed. The inclusion criteria included the peer-reviewed academic papers in English, Portuguese, Spanish, and Italian languages; the databases used were PubMed, Scopus, MEDLINE/Bireme (Virtual Library of Health - VLH), and Web of Science, which execute the query on the topic, keywords, or abstracts. Also, to be included, documents that were available with full-text access through CAPES, Google, or Google Scholar. Books, non-academic research, and content in languages other than the presented ones were represented as exclusion criteria. RESULTS: From the resulting papers, 21 articles served as the basis for this analysis. Revealed were the year of publication, the first author's institution nationality, topic, and disaster management phase for each study, which allow other researchers to understand the main topics regarding children's health care in MCIs. CONCLUSIONS: The topics regarding child's health care in MCIs found in the primary studies of this review, in order of frequency, were: Disaster Response (including the following sub-topics: simulation, education, quality of care, use of technological tools, and damage analysis); Triage; and Disaster Planning. The Emergency Medicine operation was focused on harm reduction after the occurrence of an MCI. Further studies focusing on the pre-disaster and post-disaster phases are needed.

A Descriptive Analysis of Battlefield First Responder and Combat Lifesaver Interventions during the Role 1 Phase of Care.

BACKGROUND: Battlefield first responders (BFR) are the first non-medical personnel to render critical lifesaving interventions for combat casualties, especially for massive hemorrhage where rapid control will improve survival. Soldiers receive medical instruction during initial entry training (IET) and unit-dependent medical training, and by attending the Combat Lifesaver (CLS) course. We seek to describe the interventions performed by BFRs on casualties with only BFRs listed in their chain of care within the Prehospital Trauma Registry (PHTR). METHODS: This is a secondary analysis of a dataset from the PHTR from 2003-2019. We excluded encounters with a documented medical officer, medic, or unknown prehospital provider at any time in their chain of care during the Role 1 phase to isolate only casualties with BFR medical care. RESULTS: Of the 1,357 encounters in our initial dataset, we identified 29 casualties that met inclusion criteria. Pressure dressing was the most common intervention (n=12), followed by limb tourniquets (n=4), IV fluids (n=3), hemostatic gauze (n=2), and wound packing (n=2). Bag-valve-masks, chest seals, extremity splints, and nasopharyngeal airways (NPA) were also used (n=1 each). Notably absent were backboards, blizzard blankets, cervical collars, eye shields, pelvic splints, hypothermia kits, chest tubes, supraglottic airways (SGA), intraosseous (I/O) lines, and needle decompression (NDC). CONCLUSIONS: Despite limited training, BFRs employ vital medical skills in the prehospital setting. Our data show that BFRs largely perform medical interventions within the scope of their medical knowledge and training. Better datasets with efficacy and complication data are needed.

Skin Temperature of Slaughter Pigs With Tail Lesions.

The aim of this study was to assess the effect of tail lesion severity on skin temperature of slaughter pigs measured at the base of the tail and the ear by infrared thermography camera and to evaluate the association between the temperature measurements. Pigs were randomly selected in the lairage, containing ~200 pigs/pen. Tail lesions were scored according to severity, using a 0-4 scale. Tail lesion scores 0 and 1 were summed as it was difficult to distinguish healed lesions from mild lesions due to animal dirtiness. In total, 269 study pigs were imaged at the two locations. The effect of tail lesion score and sex of the pig on the highest temperature of the infrared image areas were analyzed using linear mixed models. Association between the tail base and ear base temperatures was evaluated using Pearson correlation. Skin temperature measured at the base of the tail was significantly lower for tails scored 0-1 than for all other tail lesion scores (P < 0.05). Pigs with tail lesion scored 2 had significantly lower skin temperatures at the base of the tail than pigs with tail lesion scored 3 or 4 (P < 0.05) while there was no difference in skin temperature at the base of the tail between pigs with tail lesion scored 3 and 4 (P > 0.05). Skin temperature measured at the ear base was significantly lower for pigs with tail lesion scored 0-1 than pigs of all other tail lesion scores (P < 0.05) with no difference between the other scores (P > 0.05). Furthermore, there was an association between the two measurements (r = 0.50; P < 0.001). The findings suggest that even pigs with moderate tail lesions (score 2) may have general inflammation and infection, evidenced by the elevated systemic temperature compared to pigs with none or mild tail lesion (score 0-1).

Long-Term Public Health Responses in High-Impact Weather Events: Hurricane Maria and Puerto Rico as a Case Study.

This statement responds to the public health challenges in Puerto Rico in the wake of Hurricane Maria during September 2017. As a result of Maria, and to a certain extent Hurricane Irma, the territory sustained unprecedented damage. We call for a mid- and long-term public health response and research to assess the long-term impacts of high-impact weather events, such as Maria's effects on Puerto Rico, including impacts on vulnerable populations' environmental health and well-being.

Prehospital and First Hospital System Response to a Terrorist Attack in Bogotá, Colombia.

Background: Assembling an effective medical response for an overwhelming number of casualties has become a priority worldwide. Terrorist attacks have been part of the Colombian contemporaneous history. On February 7, 2003, a terrorist car bomb explosion occurred inside a private club in Bogotá, causing the largest number of casualties of all terrorist attacks for over 15 years. The present study analyses the hospital and prehospital responses to this mass casualty event by characterizing the patterns of injury, resource allocation, and outcome in a tertiary-level hospital where most of the casualties were treated. Materials and methods: This is a retrospective chart review of the patients brought to a single hospital (La Clínica del Country), which was the nearest to the terrorist attack. Demographics, severity of injury, patterns of injury, prehospital care, and outcomes were determined from the hospital medical records and government registries. Results: Of the 240 victims, 35 died at the explosion site (immediate mortality 17%). The 205 survivors were dispersed throughout the city, of whom 63 patients came to La Clínica del Country hospital. Most of these patients were evaluated only clinically and deemed not serious. The main mechanism of trauma was blunt (81.4%). The mean injury severity score (ISS) was 5.6 ± 8.3. Ten patients required emergent surgical intervention and 14 patients were admitted. The in-hospital mortality was 20%. Conclusion: This mass casualty event was a true test for the Colombian emergency medical system and disaster preparedness. The medical response and resource optimization resulted in an overall mortality rate similar to those observed in the recent European and North American bombings. Despite the limited resources, the continuous challenge of terrorist's attacks in Colombia made the country feel the need for training and preparing the healthcare professionals, allowing effective delivery of medical care.

Introducción: La organización de una respuesta médica efectiva a un número excesivo de víctimas de ataques terroristas se ha convertido en una prioridad en el mundo. Los ataques terroristas han sido parte de la historia colombiana contemporánea.

El objetivo de este estudio es determinar la respuesta del sistema pre y hospitalario a un ataque terrorista masivo, caracterizar los patrones de lesión, utilización de recursos y desenlaces en un hospital de primer nivel, donde la mayoría de las víctimas fueron atendidas. Métodos: Este es un estudio retrospectivo de la revisión de 43 historias clínicas de 63 pacientes que fueron llevados al hospital privado más cercano después de un ataque terroristas. La información demográfica, la severidad, el patrón de las lesiones y los desenlaces fueron determinados a partir de las historias clínicas y los registros gubernamentales. Resultados: Treinta y cinco personas murieron en la escena y 205 personas fueron lesionadas (mortalidad inmediata de 17%). 63 pacientes fueron transferidos a nuestros hospitales. La mayoría de los pacientes fueron valorados clínicamente y no tenían lesiones serias. El principal mecanismos de trauma fue cerrado. El promedio de ISS fue 5.6 ± 8.3. Diez pacientes requirieron intervenciones quirúrgicas de urgencia y 14 fueron admitidos al hospital. La mortalidad crítica fue de 20%. Conclusione: Este incidente fue un verdadero examen a nuestro sistema médico de emergencias y plan de desastres hospitalario. Nuestro sistema médico optimizó los recursos resultando en una mortalidad crítica similar a la de las bombas ocurridas en Europa y Norte América. El desafío permanente de confrontar los ataques terroristas en Colombia ha proporcionado entrenamiento y preparación para asegurar un cuidado médico efectivo, aun con recursos limitados. Palabras clave: Ataque terrorista, Bomba, Evento con lesionados masivos, Respuesta medica.

Simulação de incidente com múltiplas vítimas: treinando profissionais e ensinando universitários / Multiple victims incident simulation: training professionals and university teaching

RESUMO Objetivo: descrever estratégia de ensino a partir da simulação de Incidente de Múltiplas Vítimas (IMV), discutindo e avaliando a atuação dos discentes envolvidos no atendimento inicial às vítimas de trauma. Métodos: estudo transversal com abordagem quantitativa que contemplou a execução de uma simulação realística de IMV, envolvendo discentes, docentes dos Cursos de Medicina e de Enfermagem, além de profissionais do atendimento pré-hospitalar. Resultados: a partir da análise de 17 checklists, foi possível perceber que a classificação segundo o método START (Simple Triage And Rapid Treatment) aconteceu de forma correta em 94,1% dos atendimentos. Seguindo a avaliação primária com o mnemônico ABCDE, todas as etapas foram realizadas de forma correta em 70%. Contudo, só houve oferta de oxigênio em alto fluxo em 64,7% dos atendimentos. A pesquisa por fontes de sangramento visíveis e ocultas foi realizada em 70,6% dos atendimentos. A avaliação neurológica com a escala de coma de Glasgow e avaliação pupilar ocorreu em 70,6% das vítimas. A exposição da vítima foi realizada em 70,6% dos atendimentos. Conclusão: ambientes simulados permitem a consolidação e o aperfeiçoamento de competências e habilidades profissionais, principalmente quando se trata de uma área pouco treinada na graduação, como o IMV. O treinamento precoce e o atendimento em equipe estimulam o raciocínio clínico, a integração e a comunicação, aspectos essenciais diante de situações caóticas.

ABSTRACT Objective: to describe the teaching strategy based on the Multiple Victims Incident (MVI) simulation, discussing and evaluating the performance of the students involved in the initial care of trauma victims. Methods: a cross-sectional, and quantitative study was performed. A realistic MVI simulation involving students, and professionals from nursery and medical schools, as well as a prehospital care team was performed. Results: it was possible to notice that the classification according to the START method (Simple Triage and Rapid Treatment) was correct in 94.1% of the time from the analysis of 17 preestablished checklists. Following the primary evaluation with the ABCDE mnemonic, all steps were performed correctly in 70%. However, there was only supply of oxygen in high flow in 64.7% of the examination. The search for visible and hidden bleeding was performed in 70.6% of the examination. The neurological evaluation with the Glasgow coma scale and pupillary evaluation occurred in 70.6% of the victims. The victims exposure was performed in 70.6% of the examination. Conclusion: a simulated environment allows the consolidation and improvement of professional skills, especially when we are talking about a poorly trained area during the undergraduate program, such as the MVI. Early training and teamwork encourage clinical thinking, integration and communication, essential abilities when facing chaotic situations.

Field Expedient Vasopressors During Aeromedical Evacuation: A Case Series from the Puerto Rico Disaster Response.

IntroductionEmergency physicians are using bolus-dose vasopressors to temporize hypotensive patients until more definitive blood pressure support can be established. Despite a paucity of clinical outcome data, emergency department applications are expanding into the prehospital setting. This series presents two cases of field expedient vasopressor use by emergency medicine providers for preflight stabilization during aeromedical evacuation to a hospital ship as part of the United States Navy disaster response in Puerto Rico. A critical approach and review of the literature are discussed.Case ReportTwo critically ill patients were managed in an austere environment as a result of the devastation from Hurricane Maria (Yabucoa, Puerto Rico; 2017). They both exhibited signs of respiratory distress, hemodynamic instability, and distributive shock requiring definitive airway management and hemodynamic support prior to aeromedical evacuation.DiscussionThe novel use of field expedient vasopressors prior to induction for rapid sequence intubation was successfully and safely employed in both cases. Both patients had multiple risk factors for peri-induction cardiac arrest given their presenting hemodynamics. Despite their illness severity, both patients were induced, transported, and ultimately admitted to the intensive care unit (ICU) in stable condition following administration of the field expedient vasopressors.Conclusion:Field expedient vasopressors were safely and effectively employed in an austere field environment during a disaster response. This case series contributes to the growing body of literature of safe bolus-dose vasopressor use by emergency physicians to temporize hypotensive patients in resource-constrained situations.

Cuidado de heridos en el combate táctico / Care of wounded in tactical combat

Introducción: las fuerzas armadas norteamericanas han estado desarrollando un sistema de tratamiento y evacuación médico expedicionario que permite disminuir el número de fallecidos hasta valores muy bajos. Uno de los factores que ha facilitado este resultado es el protocolo de tratamiento de las bajas sanitarias en combates tácticos conocido en inglés como Tactical Combat Casualty Care. Objetivo: brindar información actualizada sobre el origen y conceptos de este. Métodos: se revisó la literatura internacional utilizando combinaciones de palabras claves relacionadas con este tema mediante buscadores (Pubmed, Clinicalkey, Hinari, Ebsco), desde enero del 2001 hasta noviembre del 2016. Desarrollo: en el año 1984 el Coronel Ronald Bellamy del ejército de los EE.UU. en su artículo denominado Causas de muertes en el combate terrestre convencional. Implicaciones en las investigaciones sobre las bajas sanitarias, desafió a la comunidad militar para que enfrentara estas realidades, revisó las causas de muerte en escenarios combativos analizando los datos históricos sobre heridas recogidos por diferentes investigadores que se basaron en la efectividad de las diferentes municiones durante la guerra de Vietnam. Definió que durante las operaciones combativas terrestres convencionales, la mayoría de las muertes resultan por heridas catastróficas. Conclusiones: este protocolo surgió por la necesidad de disminuir las muertes prevenibles en los escenarios combativos y bajo consideraciones tácticas. Debido a su gran repercusión en el tratamiento del lesionado en los escenarios combativos se ha convertido en el documento rector de los servicios médicos de la mayoría de los ejércitos del mundo(AU)

Introduction: The United States Armed Forces have been developing an expeditionary medical treatment and evacuation system that allows to reduce the number of deaths to very low. One of the factors that has facilitated this result is the Tactical Combat Casualty Care protocol. Objective: To provide updated information on the origin and concepts of this. Methods: The international literature was reviewed using combinations of keywords related to this topic through search engines (Pubmed, Clinicalkey, Hinari, Ebsco), from January 2001 to November 2016. Body: In 1984 Colonel Ronald Bellamy of the Army of the USA in his article entitled Causes of deaths in conventional terrestrial combat. Implications of Health Disposal Investigations, challenged the military community to address these realities, reviewed causes of death in combat scenarios by analyzing historical data on injuries collected by different researchers who relied on the effectiveness of different ammunition during the Viet Nam war. He stated that during conventional ground fighting operations, most of the deaths result from catastrophic injuries. Conclusions: This protocol arose because of the need to reduce preventable deaths in combat scenarios and under tactical considerations. Due to its great impact in the treatment of the injured in the combative scenarios has become the guiding document of the medical services of the majority of the armies of the world(AU)

Estimation of the Demand for Hospital Care After a Possible High-Magnitude Earthquake in the City of Lima, Peru.

Introduction A model prepared by National Civil Defense (INDECI; Lima, Peru) estimated that an earthquake with an intensity of 8.0 Mw in front of the central coast of Peru would result in 51,019 deaths and 686,105 injured in districts of Metropolitan Lima and Callao. Using this information as a base, a study was designed to determine the characteristics of the demand for treatment in public hospitals and to estimate gaps in care in the hours immediately after such an event. METHODS: A probabilistic model was designed that included the following variables: demand for hospital care; time of arrival at the hospitals; type of medical treatment; reason for hospital admission; and the need for specialized care like hemodialysis, blood transfusions, and surgical procedures. The values for these variables were obtained through a literature search of the databases of the MEDLINE medical bibliography, the Cochrane and SciELO libraries, and Google Scholar for information on earthquakes over the last 30 years of over magnitude 6.0 on the moment magnitude scale. RESULTS: If a high-magnitude earthquake were to occur in Lima, it was estimated that between 23,328 and 178,387 injured would go to hospitals, of which between 4,666 and 121,303 would require inpatient care, while between 18,662 and 57,084 could be treated as outpatients. It was estimated that there would be an average of 8,768 cases of crush syndrome and 54,217 cases of other health problems. Enough blood would be required for 8,761 wounded in the first 24 hours. Furthermore, it was expected that there would be a deficit of hospital beds and operating theaters due to the high demand. CONCLUSION: Sudden and violent disasters, such as earthquakes, represent significant challenges for health systems and services. This study shows the deficit of preparation and capacity to respond to a possible high-magnitude earthquake. The study also showed there are not enough resources to face mega-disasters, especially in large cities. Bambarén C , Uyen A , Rodriguez M .

Response and legislative changes after the Kiss nightclub tragedy in Santa Maria/RS/Brazil: Learning from a large-scale burn disaster.

PURPOSE: A major fire occurred on January 27, 2013, at 02:30 at Kiss nightclub in the city of Santa Maria, State of Rio Grande do Sul, in Southern Brazil. In this retrospective report, we aimed to describe the nightclub fire event, its immediate consequences, and evaluated its impact on legislation. Our objective was to disseminate the lessons we learned from this large-scale nightclub fire disaster. METHODS: We conducted a literature review in PubMed and Lilacs database from 2013 to 2015 related to the nightclub Kiss, Santa Maria, fire, burns, and similar events worldwide over the past 15 years. We searched in the general press and online media information sites, and seeking legislation about this topic at the federal level in Brazil. We reported on the legislation changes that resulted from this nightclub fire. RESULTS: Current federal legislation on fire prevention and the scope of public safety, including night clubs and discos, states is the duty of the state and everyone's responsibility, pursuant to Article 144 of the Federal Constitution of Brazil. Thus, the federal union, individual states and municipalities have the power to legislate on fire prevention, and especially to ensure the security of the population. A state law called "Law Kiss", was passed in 2014, establishing standards on safety, prevention and protection against fire in buildings and areas of fire risk in the state of Rio Grande do Sul. On a national level, a law of prevention and fire fighting in Brazil was also drafted after the Santa Maria disaster (Law project no. 4923, 2013). Currently, this bill is still awaiting sanction before it can take effect. CONCLUSION: As we push for enactment of the national law of prevention and fire fighting in Brazil, we will continue emphasizing fire prevention, fire protection, fire fighting, means of escape and proper management. All similar events in this and other countries remind us that similar tragedies may occur anywhere, and that the analysis of facts, previous mistakes, during and after the incident are crucial to our understanding, and will help us lessen the chance of future occurrences.

Culture time and reagent minimization in the chemical PCC assay.

The possibility to reduce the culture time and volume of blood and reagents required for the chemical Premature Chromosome Condensation (PCC) assay is demonstrated in this work. Peripheral whole blood was exposed to gamma radiation (1-20 Gy). Lymphocytes were cultured for 40 h, using 50 µl of blood and 450 µl of culture medium. The dose-response curves were adjusted, using length ratio (LR) of the longest to the shortest chromosome piece, and the frequency of rings per cell. No statistical differences were found between the results obtained with this method and those reported with the classical PCC assay culture. The minimization of culture time and reagents in combination with the automatic measurement of the LR of the chromosome pieces, or the scoring of rings, can be a valuable biodosimetry tool in a mass casualty scenario.

Preparedness for the Rio 2016 Olympic Games: hospital treatment capacity in georeferenced areas / Preparação para os Jogos Olímpicos Rio 2016: capacidade de tratamento hospitalar em áreas georreferenciadas / La preparación para los Juegos Olímpicos de Río 2016: capacidad de tratamiento hospitalario en áreas georreferenciadas

Abstract: Recently, Brazil has hosted mass events with recognized international relevance. The 2014 FIFA World Cup was held in 12 Brazilian state capitals and health sector preparedness drew on the history of other World Cups and Brazil's own experience with the 2013 FIFA Confederations Cup. The current article aims to analyze the treatment capacity of hospital facilities in georeferenced areas for sports events in the 2016 Olympic Games in the city of Rio de Janeiro, based on a model built drawing on references from the literature. Source of data were Brazilian health databases and the Rio 2016 website. Sports venues for the Olympic Games and surrounding hospitals in a 10km radius were located by geoprocessing and designated a "health area" referring to the probable inflow of persons to be treated in case of hospital referral. Six different factors were used to calculate needs for surge and one was used to calculate needs in case of disasters (20/1,000). Hospital treatment capacity is defined by the coincidence of beds and life support equipment, namely the number of cardiac monitors (electrocardiographs) and ventilators in each hospital unit. Maracanã followed by the Olympic Stadium (Engenhão) and the Sambódromo would have the highest single demand for hospitalizations (1,572, 1,200 and 600, respectively). Hospital treatment capacity proved capable of accommodating surges, but insufficient in cases of mass casualties. In mass events most treatments involve easy clinical management, it is expected that the current capacity will not have negative consequences for participants.

Resumo: Recentemente, o Brasil sediou eventos de massa com relevância internacional reconhecida. A Copa do Mundo FIFA de 2014 foi realizada em 12 capitais estaduais e a preparação do setor da saúde contou com a história de outras Copas do Mundo e com a própria experiência do Brasil com a Copa das Confederações FIFA de 2013. O presente artigo objetivou analisar a capacidade de tratamento de instalações hospitalares em áreas georeferenciadas para eventos esportivos, nos Jogos Olímpicos de 2016, na cidade do Rio de Janeiro, com base em um modelo construído a partir da literatura. Os dados foram coletados nas bases de dados de saúde do Brasil e da página de Internet da Rio 2016. As instalações esportivas para os Jogos Olímpicos e os hospitais circundantes em um raio de 10km foram localizados por geoprocessamento; foi designada uma "área de saúde", referindo-se ao afluxo provável de pessoas a serem tratadas em caso de necessidade hospitalar. Seis fatores foram utilizados para calcular necessidades para surtos e um fator de cálculo foi usado para as desastres (20/1.000). Capacidade de tratamento hospitalar é definida pela coincidência de leitos e equipamentos de suporte de vida, ou seja, o número de monitores cardíacos (eletrocardiógrafos) e respiradores em cada unidade hospitalar. O Maracanã, seguido do Estádio Olímpico (Engenhão) e o Sambódromo, teria a maior demanda para internações (1.572, 1.200 e 600, respectivamente). A capacidade de tratamento hospitalar mostrou-se capaz de acomodar surtos, mas insuficiente em casos de vítimas em massa. Em eventos de massa, a maioria dos tratamentos envolve uma fácil gestão clínica. Espera-se que a capacidade atual não terá consequências negativas para os participantes.
