Abstract
Purpose It is now known that traumatic injury initiates a complex and dynamic immune response on the first day. It is believed that in patients with polytrauma, these immune responses contribute to the development of infectious complications. Therefore, understanding the immune response to trauma is critical to improving patient outcomes through the development of new therapies and improved resuscitation strategies. The purpose of this study is to examine the parameters of immunity in patients with severe polytrauma at the stages of surgical treatment (the nearest post-traumatic period and long-term periods) in the absence and presence of purulent-inflammatory complications. Methods We retrospectively enrolled 188 patients after severely injured trauma and 210 control group at two Level-1 Trauma Centers. Peripheral blood was collected upon presentation to the hospital and at the following time points: 1, 3, 7, 14, 21, 30, 60 and 90 days, and daily during intensive care unit admission. T-lymphocytes analyses performed using a Beckman Coulter EPICS XL flow cytometer (USA) with monoclonal antibodies (Immunotech, France). Analyses of protein levels of cytokines/chemokines, immunoglobulins, and circulating immune complexes was using ELISA. Results Under the influence of trauma, the content of T lymphocytes decreased due to the population of T-helpers. However, the number of B lymphocytes increased. The most pronounced activation of humoral immunity was observed by the 30th day of the post-traumatic period. Concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-a), interleukin-10 (IL-10) on day 1 after injury were the highest. Later, in the post-traumatic period, a gradual decrease in the initially elevated cytokines was noted. Conclusions As we continue to extrapolate new information on immune response factors associated with polytrauma, we will be better equipped to develop new therapeutic strategies to treat this serious clinical and social problem. In addition, individually adjusted immune control is an important interactive concept in polytrauma management.

Abstract
RESUMO Objetivo identificar a prevalência de doença crítica crônica e fatores associados em pacientes hospitalizados por trauma em Unidade de Terapia Intensiva. Método estudo de caso-controle, com dados de prontuários de adultos hospitalizados por trauma em uma Unidade de Terapia Intensiva, entre 2013 e 2019. Os dados foram coletados do livro de admissão de pacientes, do prontuário eletrônico e das fichas do Serviço de Controle de Infecção Hospitalar. A variável dependente foi a ocorrência de doença crítica crônica e as variáveis independentes relacionavam-se às características sociodemográficas, comorbidades, trauma, atendimento pré-hospitalar, índices prognósticos, procedimentos e complicações. Realizou-se análise de regressão logística múltipla, que estimou o Ods Ratio (OR) e respectivos intervalos de confiança (IC). Resultados a doença crítica crônica ocorreu em 150 pacientes (24,2%), dos 619 estudados. Os fatores associados à DCC foram disfunção orgânica (OR=1,09) e complicações gastrointestinais (OR=2,71). Os pacientes com doença crítica crônica, além de demandarem por procedimentos cirúrgicos, desenvolveram disfunções orgânicas em diferentes sistemas, apresentando altas pontuações nos índices de prognósticos, ou seja, um pior prognóstico, além de desenvolverem complicações. Conclusão a identificação das complicações gastrointestinais e o aumento da disfunção orgânica como fatores associados ao paciente crítico crônico tornam-se úteis para compor perfil clínico de pacientes e para planejar a assistência intensiva ao traumatizado, contribuindo, assim, para a prevenção e o manejo desses pacientes pelo enfermeiro.

Abstract
ABSTRACT Objective to identify the prevalence of chronic critical disease and associated factors in patients hospitalized for trauma in the Intensive Care Unit. Method case-control study, with data from medical records of adults hospitalized for trauma in an Intensive Care Unit, between 2013 and 2019. Data were collected from the patient admission book, the electroni cmedical records and the records of the Hospital Infection Control Service. The dependent variable was the occurrence of chronic critical disease, and the independent variables were related to sociodemographic characteristics, comorbidities, trauma, pre-hospital care, prognostic indices, procedures and complications. Multiple logistic regression analysis was performed, which estimated the Ods Ratio (OR) and respective confidence intervals (CI). Results chronic critical disease occurred in 150 patients (24.2%), of the 619 patients studied. The factors associated with CCD were organic dysfunction (OR=1.09) and gastrointestinal complications (OR=2.71). Patients with chronic critical disease, in addition to proseeding for surgical procedures, developed organic dysfunctions in different systems, presenting high scores in prognostic indexes, i.e., a worse prognosis, in addition to developing complications. Conclusion the identification of gastrointestinal complications and the increase in organic dysfunction as factors associated with chronic critical patients become useful to compose the clinical profile of patients and to plan intensive care for the traumatized patients, thus contributing to the prevention and management of these patients by nurses.

Abstract
Elimination of the posttraumatic inflammatory response and recovery of homeostasis are crucial for the positive prognosis of trauma patients. Myeloid-derived suppressor cells (MDSCs) are known to play a regulatory role in the posttraumatic immune response in mice, but their induction source and involved potential mechanism are poorly understood. Here, we report that polymorphonuclear MDSCs (PMN-MDSCs) are activated after trauma and are closely associated with the progression of the posttraumatic inflammatory response. In humans, lectin-type oxidized LDL receptor 1 (LOX1) was used to specifically characterize LOX1+ PMN-MDSCs. Trauma patients showed high intracellular reactive oxygen species (ROS) production, as well as activation of LOX1+ PMN-MDSCs. These MDSCs contribute to the anti-inflammatory immune response by regulating the Treg/Th17 and Th2/Th1 balances after trauma, increasing the levels of anti-inflammatory factors, and decreasing the levels of proinflammatory factors. The number of LOX1+ PMN-MDSCs was positively correlated with the positive clinical prognosis of trauma patients with infection. Activation of LOX1+ PMN-MDSCs is mediated by NF-κB signal, and TGF-β1 may be as an important inducer for LOX1+ PMN-MDSCs in the posttraumatic cytokine environment. In a pseudofracture trauma mouse model, we also observed the activation of PMN-MDSCs, accompanying high levels of intracellular ROS production, NF-κB phosphorylation, and changes in the inflammatory environment, in particularly by regulating the Treg/Th17 and Th2/Th1 balance. And more significantly, posttraumatic inflammation was alleviated in mice after transferring trauma-derived PMN-MDSCs, but aggravated after injecting with Gr1 agonistic antibody. These findings provide evidence for the specific role of PMN-MDSCs in the regulation of posttraumatic inflammation.
