Typical phenotypes of patients with acute respiratory failure with and without COVID-19 and their relationship with outcomes: a cohort study / Fenótipos característicos em pacientes com insuficiência respiratória aguda com e sem COVID-19 e sua relação com os desfechos: um estudo de coorte

ABSTRACT Objective: To compare, within a cohort of patients with acute respiratory failure, the phenotypes of patients with and without COVID-19 in the context of the pandemic and evaluate whether COVID-19 is an independent predictor of intensive care unit mortality. Methods: This historical cohort study evaluated 1001 acute respiratory failure patients with suspected COVID-19 admitted to the intensive care unit of 8 hospitals. Patients were classified as COVID-19 cases and non-COVID-19 cases according to real-time polymerase chain reaction results. Data on clinical and demographic characteristics were collected on intensive care unit admission, as well as daily clinical and laboratory data and intensive care unit outcomes. Results: Although the groups did not differ in terms of APACHE II or SOFA scores at admission, the COVID-19 group had more initial symptoms of fever, myalgia and diarrhea, had a longer duration of symptoms, and had a higher prevalence of obesity. They also had a lower PaO2/FiO2 ratio, lower platelet levels than non-COVID-19 patients, and more metabolic changes, such as higher levels of blood glucose, C-reactive protein, and lactic dehydrogenase. Patients with non-COVID-19 acute respiratory failure had a higher prevalence of chronic obstructive pulmonary disease/asthma and cardiopathy. Patients with COVID-19 stayed in the hospital longer and had more complications, such as acute kidney failure, severe acute respiratory distress syndrome and severe infection. The all-cause mortality rate was also higher in this group (43.7% in the COVID-19 group versus 27.4% in the non-COVID-19 group). The diagnosis of COVID-19 was a predictor of intensive care unit mortality (odds ratio, 2.77; 95%CI, 1.89 - 4.07; p < 0.001), regardless of age or Charlson Comorbidity Index score. Conclusion: In a prospective cohort of patients admitted with acute respiratory failure, patients with COVID-19 had a clearly different phenotype and a higher mortality than non-COVID-19 patients. This may help to outline more accurate screening and appropriate and timely treatment for these patients.

RESUMO Objetivo: Comparar, em uma coorte de pacientes com insuficiência respiratória aguda, os fenótipos de pacientes com e sem COVID-19, no contexto da pandemia, e avaliar se a COVID-19 é um preditor independente de mortalidade na unidade de terapia intensiva. Métodos: Este estudo de coorte histórico avaliou 1.001 pacientes com insuficiência respiratória aguda e suspeita de COVID-19 internados na unidade de terapia intensiva de oito hospitais. Os pacientes foram classificados como casos com e sem COVID-19 segundo os resultados da RT-PCR. Foram coletados dados sobre características clínicas e demográficas na admissão à unidade de terapia intensiva, bem como dados clínicos e laboratoriais diários e desfechos da unidade de terapia intensiva. Resultados: Embora os grupos não tenham diferido nos escores APACHE II ou SOFA na admissão, o grupo COVID-19 apresentou mais sintomas iniciais de febre, mialgia e diarreia e teve maior duração dos sintomas e maior prevalência de obesidade. Eles também apresentaram menor relação PaO2/FiO2 e níveis mais baixos de plaquetas do que os pacientes sem COVID-19 e mais alterações metabólicas, como níveis mais altos de glicemia, proteína C-reativa e desidrogenase lática. Os pacientes com insuficiência respiratória aguda sem COVID-19 apresentaram maior prevalência de doença pulmonar obstrutiva crônica/asma e cardiopatia. Os pacientes com COVID-19 permaneceram mais tempo no hospital e tiveram mais complicações, como insuficiência renal aguda, síndrome do desconforto respiratório agudo grave e infecção grave. A taxa de mortalidade por todas as causas também foi maior nesse grupo (43,7% no grupo com COVID-19 versus 27,4% no grupo sem COVID-19). O diagnóstico de COVID-19 foi um preditor de mortalidade na unidade de terapia intensiva (razão de chances de 2,77; IC95% 1,89 - 4,07; p < 0,001), independentemente da idade ou da pontuação do Índice de Comorbidade de Charlson. Conclusão: Em uma coorte prospectiva de pacientes admitidos com insuficiência respiratória aguda, os pacientes com COVID-19 apresentaram fenótipo claramente diferente e uma mortalidade mais alta do que os pacientes sem COVID-19. Isso pode ajudar a traçar uma triagem mais precisa e um tratamento adequado e oportuno para esses pacientes.

Accuracy of the persistent AKI risk index in predicting acute kidney injury in patients admitted to the intensive care unit for acute respiratory failure.

OBJECTIVE: To evaluate the accuracy of the persistent AKI risk index (PARI) in predicting acute kidney injury within 72 hours after admission to the intensive care unit, persistent acute kidney injury, renal replacement therapy, and death within 7 days in patients hospitalized due to acute respiratory failure. METHODS: This study was done in a cohort of diagnoses of consecutive adult patients admitted to the intensive care unit of eight hospitals in Curitiba, Brazil, between March and September 2020 due to acute respiratory failure secondary to suspected COVID-19. The COVID-19 diagnosis was confirmed or refuted by RT-PCR for the detection of SARS-CoV-2. The ability of PARI to predict acute kidney injury at 72 hours, persistent acute kidney injury, renal replacement therapy, and death within 7 days was analyzed by ROC curves in comparison to delta creatinine, SOFA, and APACHE II. RESULTS: Of the 1,001 patients in the cohort, 538 were included in the analysis. The mean age was 62 ± 17 years, 54.8% were men, and the median APACHE II score was 12. At admission, the median SOFA score was 3, and 83.3% had no renal dysfunction. After admission to the intensive care unit, 17.1% had acute kidney injury within 72 hours, and through 7 days, 19.5% had persistent acute kidney injury, 5% underwent renal replacement therapy, and 17.1% died. The PARI had an area under the ROC curve of 0.75 (0.696 - 0.807) for the prediction of acute kidney injury at 72 hours, 0.71 (0.613 - 0.807) for renal replacement therapy, and 0.64 (0.565 - 0.710) for death. CONCLUSION: The PARI has acceptable accuracy in predicting acute kidney injury within 72 hours and renal replacement therapy within 7 days of admission to the intensive care unit, but it is not significantly better than the other scores.

Epidemiology and disease burden of patients requiring neurocritical care: a Brazilian multicentre cohort study.

Acute neurological emergencies are highly prevalent in intensive care units (ICUs) and impose a substantial burden on patients. This study aims to describe the epidemiology of patients requiring neurocritical care in Brazil, and their differences based on primary acute neurological diagnoses and to identify predictors of mortality and unfavourable outcomes, along with the disease burden of each condition at intensive care unit admission. This prospective cohort study included patients requiring neurocritical care admitted to 36 ICUs in four Brazilian regions who were followed for 30 days or until ICU discharge (Aug-Sep in 2018, 1 month). Of 4245 patients admitted to the participating ICUs, 1194 (28.1%) were patients with acute neurological disorders requiring neurocritical care and were included. Patients requiring neurocritical care had a mean mortality rate 1.7 times higher than ICU patients not requiring neurocritical care (17.21% versus 10.1%, respectively). Older age, emergency admission, higher number of potential secondary injuries, and worse APACHE II, SAPS III, SOFA, and Glasgow coma scale scores on ICU admission are independent predictors of mortality and poor outcome among patients with acute neurological diagnoses. The estimated total DALYs were 4482.94 in the overall cohort, and the diagnosis with the highest DALYs was traumatic brain injury (1634.42). Clinical, epidemiological, treatment, and ICU outcome characteristics vary according to the primary neurologic diagnosis. Advanced age, a lower GCS score and a higher number of potential secondary injuries are independent predictors of mortality and unfavourable outcomes in patients requiring neurocritical care. The findings of this study are essential to guide education policies, prevention, and treatment of severe acute neurocritical diseases.

Adaptation and validation of the Brazilian version of the Measure of Moral Distress for Healthcare Professionals (MMD-HP BR) in the context of palliative care.

BACKGROUND: The Measure of Moral Distress for Health Care Professionals (MMD-HP) scale corresponds to the update of the globally recognized Moral Distress Scale-Revised (MDS-R). Its purpose is to measure moral distress, which is a type of suffering caused in a professional prevented from acting according to one's moral convictions due to external or internal barriers. Thus, this study has the objective to translate, culturally adapt, and validate the Brazilian version of the MMD-HP BR in the context of Palliative Care (PC). METHODS: The study had the following steps: translation, cross-cultural adaptation and validation. The MMD-HP BR is composed of 27 Likert-rated items for frequency and intensity of moral distress. In total, 332 health professionals who work in PC participated in the study, 10 in the pre-test stage, and 322 in the validation stage. RESULTS: It was possible to identify six factors, which together explain 64.75% of the model variation. The reliability of Cronbach's alpha was 0.942. In addition, the score was higher in those who are considering or have already left their positions due to moral distress, compared to those who do not or have never had such an intention. CONCLUSIONS: MMD-HP BR is a reliable and valid instrument to assess moral distress in the PC context. It is suggested that the scale be standardized in other healthcare contexts, such as clinical settings. In addition, further research on moral distress is encouraged to identify and reduce the phenomenon and its consequences.

O PARI apresentou área sob a curva ROC de 0,75 (0,696 - 0,807) para predição de injúria renal aguda em 72 horas, 0,71 (0,613 - 0,807) para terapia de substituição renal e 0,64 (0,565 - 0,710) para mortalidade. Conclusão: O PARI tem acurácia aceitável na predição de injúria renal aguda em 72 horas e terapia de substituição renal em até 7 dias da admissão na unidade de terapia intensiva, porém sem diferença significativa dos demais escores.

Dysglycemias in patients admitted to ICUs with severe acute respiratory syndrome due to COVID-19 versus other causes - a cohort study.

BACKGROUND: Dysglycemias have been associated with worse prognosis in critically ill patients with COVID-19, but data on the association of dysglycemia with COVID-19 in comparison with other forms of severe acute respiratory syndrome are lacking. This study aimed to compare the occurrence of different glycemic abnormalities in patients with severe acute respiratory syndrome and COVID-19 admitted to intensive care units versus glycemic abnormalities in patients with severe acute respiratory syndrome from other causes, to evaluate the adjusted attributable risk associated with COVID-19 and dysglycemia and to assess the influence of these dysglycemias on mortality. METHODS: We conducted a retrospective cohort of consecutive patients with severe acute respiratory syndrome and suspected COVID-19 hospitalized in intensive care units between March 11 and September 13, 2020, across eight hospitals in Curitiba-Brazil. The primary outcome was the influence of COVID-19 on the variation of the following parameters of dysglycemia: highest glucose level at admission, mean and highest glucose levels during ICU stay, mean glucose variability, percentage of days with hyperglycemia, and hypoglycemia during ICU stay. The secondary outcome was the influence of COVID-19 and each of the six parameters of dysglycemia on hospital mortality within 30 days from ICU admission. RESULTS: The sample consisted of 841 patients, of whom 703 with and 138 without COVID-19. Comparing patients with and without COVID-19, those with COVID-19 had significantly higher glucose peaks at admission (165 mg/dL vs. 146 mg/dL; p = 0.002) and during ICU stay (242 mg/dL vs. 187md/dL; p < 0.001); higher mean daily glucose (149.7 mg/dL vs. 132.6 mg/dL; p < 0.001); higher percentage of days with hyperglycemia during ICU stay (42.9% vs. 11.1%; p < 0.001); and greater mean glucose variability (28.1 mg/dL vs. 25.0 mg/dL; p = 0.013). However, these associations were no longer statistically significant after adjustment for Acute Physiology and Chronic Health Evaluation II scores, Sequential Organ Failure Assessment scores, and C-reactive protein level, corticosteroid use and nosocomial infection. Dysglycemia and COVID-19 were each independent risk factors for mortality. The occurrence of hypoglycemia (< 70 mg/dL) during ICU stay was not associated with COVID-19. CONCLUSION: Patients with severe acute respiratory syndrome due to COVID-19 had higher mortality and more frequent dysglycemia than patients with severe acute respiratory syndrome due to other causes. However, this association did not seem to be directly related to the SARS-CoV-2 infection.

Associations between Lifestyle and Sociodemographic Factors in Medical Students: A Cross Sectional Study.

Background: Identifying lifestyle characteristics in higher education can lead to effective interventions that benefit both individuals and communities. Methods: This cross-sectional survey-based study was conducted on medical students of a private university using the Fantastic Lifestyle Questionnaire (FLQ) to assess healthy lifestyles, as well as a custom sociodemographic questionnaire. Additionally, correlations among sociodemographic factors and alcohol intake, activity, tobacco and toxins, family and friends, insight, nutrition, type of behavior, career, sleep, seatbelt, stress, and safe sex domains were assessed. Results: This study assessed 188 lifestyle profiles, of which 148 have complete data for evaluating the total FLQ score. The majority of evaluated lifestyles were characterized as "good (42.5%)" and "very good (35.8%)", and correlations were identified between the total FLQ score and between the preclinical and later course phases, the 18-20 years and older age brackets, and any romantic relationship and being single. Additional associations were observed for the other domains with other sociodemographic factors. Conclusion: Medical students frequently present with a lifestyle that may be improved through various targeted interventions.

Analysis of primary care of victims of interpersonal and self inflicted violence during the COVID-19 pandemic.

OBJECTIVES: to analyze the epidemiological profile of aggression victims admitted at the emergency room on a trauma hospital during the COVID-19 pandemic, to compare these data in different restriction periods and with prepandemic data from the same service. METHODS: cross-sectional study with probabilistic sampling using medical records of patients who were victims of aggression admitted at the hospital between June 2020 and May 2021. In addition to the epidemiological variables, other variables collected were the current restriction level, mechanism of aggression, resulting injuries and the Revised Trauma Score (RTS). The data was compared between the three restriction levels and the proportion of attendances during the study period was compared with the pre-pandemic study (December 2016 to February 2018). RESULTS: the average age was 35.5 years, 86.1% of the patients were male and 61.6% of the attendances were due to blunt injury. The highest average of attendances per day occurred during the "yellow" restriction level (2.9), however there was no significant difference when comparing the restriction periods two by two. There was also no significant difference either in the analysis of the standardized residuals of the proportions of aggressions or the mechanism of aggression in the pre-pandemic and pandemic periods. CONCLUSIONS: there was a predominance of attendances due to blunt trauma and in young male patients. There was no significant difference between the average daily attendance for aggression during the three restriction levels and between the proportion of attendances in the pre-pandemic and pandemic period.

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.

Diagnostic accuracy of a set of clinical and radiological criteria for screening of COVID-19 using RT-PCR as the reference standard.

BACKGROUND: The gold-standard method for establishing a microbiological diagnosis of COVID-19 is reverse-transcriptase polymerase chain reaction (RT-PCR). This study aimed to evaluate the accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of a set of clinical-radiological criteria for COVID-19 screening in patients with severe acute respiratory failure (SARF) admitted to intensive care units (ICUs), using reverse-transcriptase polymerase chain reaction (RT-PCR) as the reference standard. METHODS: Diagnostic accuracy study including a historical cohort of 1009 patients consecutively admitted to ICUs across six hospitals in Curitiba (Brazil) from March to September, 2020. The sample was stratified into groups by the strength of suspicion for COVID-19 (strong versus weak) using parameters based on three clinical and radiological (chest computed tomography) criteria. The diagnosis of COVID-19 was confirmed by RT-PCR (referent). RESULTS: With respect to RT-PCR, the proposed criteria had 98.5% (95% confidence interval [95% CI] 97.5-99.5%) sensitivity, 70% (95% CI 65.8-74.2%) specificity, 85.5% (95% CI 83.4-87.7%) accuracy, PPV of 79.7% (95% CI 76.6-82.7%) and NPV of 97.6% (95% CI 95.9-99.2%). Similar performance was observed when evaluated in the subgroups of patients admitted with mild/moderate respiratory disfunction, and severe respiratory disfunction. CONCLUSION: The proposed set of clinical-radiological criteria were accurate in identifying patients with strong versus weak suspicion for COVID-19 and had high sensitivity and considerable specificity with respect to RT-PCR. These criteria may be useful for screening COVID-19 in patients presenting with SARF.

Epidemiological and clinical characteristics predictive of ICU mortality of patients with traumatic brain injury treated at a trauma referral hospital - a cohort study.

BACKGROUND: Traumatic brain injury (TBI) has substantial physical, psychological, social and economic impacts, with high rates of morbidity and mortality. Considering its high incidence, the aim of this study was to identify epidemiological and clinical characteristics that predict mortality in patients hospitalized for TBI in intensive care units (ICUs). METHODS: A retrospective cohort study was carried out with patients over 18 years old with TBI admitted to an ICU of a Brazilian trauma referral hospital between January 2012 and August 2019. TBI was compared with other traumas in terms of clinical characteristics of ICU admission and outcome. Univariate and multivariate analyses were used to estimate the odds ratio for mortality. RESULTS: Of the 4816 patients included, 1114 had TBI, with a predominance of males (85.1%). Compared with patients with other traumas, patients with TBI had a lower mean age (45.3 ± 19.1 versus 57.1 ± 24.1 years, p < 0.001), higher median APACHE II (19 versus 15, p < 0.001) and SOFA (6 versus 3, p < 0.001) scores, lower median Glasgow Coma Scale (GCS) score (10 versus 15, p < 0.001), higher median length of stay (7 days versus 4 days, p < 0.001) and higher mortality (27.6% versus 13.3%, p < 0.001). In the multivariate analysis, the predictors of mortality were older age (OR: 1.008 [1.002-1.015], p = 0.016), higher APACHE II score (OR: 1.180 [1.155-1.204], p < 0.001), lower GCS score for the first 24 h (OR: 0.730 [0.700-0.760], p < 0.001), greater number of brain injuries and presence of associated chest trauma (OR: 1.727 [1.192-2.501], p < 0.001). CONCLUSION: Patients admitted to the ICU for TBI were younger and had worse prognostic scores, longer hospital stays and higher mortality than those admitted to the ICU for other traumas. The independent predictors of mortality were older age, high APACHE II score, low GCS score, number of brain injuries and association with chest trauma.

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.

Analysis of primary care of victims of interpersonal and self inflicted violence during the COVID-19 pandemic / Análise do atendimento primário de pacientes vítimas de violência interpessoal e autodirigida durante a pandemia da COVID-19

ABSTRACT Objectives: to analyze the epidemiological profile of aggression victims admitted at the emergency room on a trauma hospital during the COVID-19 pandemic, to compare these data in different restriction periods and with prepandemic data from the same service. Methods: cross-sectional study with probabilistic sampling using medical records of patients who were victims of aggression admitted at the hospital between June 2020 and May 2021. In addition to the epidemiological variables, other variables collected were the current restriction level, mechanism of aggression, resulting injuries and the Revised Trauma Score (RTS). The data was compared between the three restriction levels and the proportion of attendances during the study period was compared with the pre-pandemic study (December 2016 to February 2018). Results: the average age was 35.5 years, 86.1% of the patients were male and 61.6% of the attendances were due to blunt injury. The highest average of attendances per day occurred during the "yellow" restriction level (2.9), however there was no significant difference when comparing the restriction periods two by two. There was also no significant difference either in the analysis of the standardized residuals of the proportions of aggressions or the mechanism of aggression in the pre-pandemic and pandemic periods. Conclusions: there was a predominance of attendances due to blunt trauma and in young male patients. There was no significant difference between the average daily attendance for aggression during the three restriction levels and between the proportion of attendances in the pre-pandemic and pandemic period.

RESUMO Objetivo: analisar o perfil epidemiológico dos pacientes vítimas de agressão admitidos na sala de emergência de um hospital de trauma durante a pandemia da COVID-19, comparar tais dados entre os diferentes períodos de restrição e com os dados de um estudo pré-pandêmico do mesmo hospital. Métodos: estudo transversal com amostragem probabilística utilizando prontuários de pacientes vítimas de agressão admitidos no referido hospital entre junho de 2020 e maio de 2021. Além das variáveis epidemiológicas, coletou-se o nível de restrição vigente, o mecanismo de agressão, as lesões resultantes e o Revised Trauma Score (RTS). Os dados foram comparados entre os três níveis e a proporção de atendimentos no período do estudo foi comparada com a do estudo pré-pandêmico (dezembro de 2016 a fevereiro de 2018). Resultados: a média etária foi de 35,5 anos, 86,1% dos pacientes eram do sexo masculino. e 61,6% dos atendimentos corresponderam a agressão física por ferimento contuso. A maior média de atendimentos por dia ocorreu durante o nível amarelo (2,9), contudo não houve diferença significativa nos atendimentos quando comparados os períodos de restrição dois a dois. Também não houve diferença significativa tanto na análise dos resíduos padronizados das proporções de agressões quanto em cada mecanismo de agressão nos períodos pré-pandêmico e pandêmico. Conclusões: houve predominância de atendimentos por agressão por trauma contuso e em pacientes jovens do sexo masculino. Não houve diferença significativa entre a média diária de atendimentos por agressão durante os três níveis de restrição implementados e entre a proporção de atendimentos do período pré-pandemico e pandêmico.

Typical phenotypes of patients with acute respiratory failure with and without COVID-19 and their relationship with outcomes: a cohort study.

OBJECTIVE: To compare, within a cohort of patients with acute respiratory failure, the phenotypes of patients with and without COVID-19 in the context of the pandemic and evaluate whether COVID-19 is an independent predictor of intensive care unit mortality. METHODS: This historical cohort study evaluated 1001 acute respiratory failure patients with suspected COVID-19 admitted to the intensive care unit of 8 hospitals. Patients were classified as COVID-19 cases and non-COVID-19 cases according to real-time polymerase chain reaction results. Data on clinical and demographic characteristics were collected on intensive care unit admission, as well as daily clinical and laboratory data and intensive care unit outcomes. RESULTS: Although the groups did not differ in terms of APACHE II or SOFA scores at admission, the COVID-19 group had more initial symptoms of fever, myalgia and diarrhea, had a longer duration of symptoms, and had a higher prevalence of obesity. They also had a lower PaO2/FiO2 ratio, lower platelet levels than non-COVID-19 patients, and more metabolic changes, such as higher levels of blood glucose, C-reactive protein, and lactic dehydrogenase. Patients with non-COVID-19 acute respiratory failure had a higher prevalence of chronic obstructive pulmonary disease/asthma and cardiopathy. Patients with COVID-19 stayed in the hospital longer and had more complications, such as acute kidney failure, severe acute respiratory distress syndrome and severe infection. The all-cause mortality rate was also higher in this group (43.7% in the COVID-19 group versus 27.4% in the non-COVID-19 group). The diagnosis of COVID-19 was a predictor of intensive care unit mortality (odds ratio, 2.77; 95%CI, 1.89 - 4.07; p < 0.001), regardless of age or Charlson Comorbidity Index score. CONCLUSION: In a prospective cohort of patients admitted with acute respiratory failure, patients with COVID-19 had a clearly different phenotype and a higher mortality than non-COVID-19 patients. This may help to outline more accurate screening and appropriate and timely treatment for these patients.

An open-label randomized controlled trial evaluating the efficacy of chloroquine/hydroxychloroquine in severe COVID-19 patients.

Despite several studies designed to evaluate the efficacy of chloroquine and hydroxychloroquine in the treatment of coronavirus disease 2019 (COVID-19), there is still doubt about the effects of these drugs, especially in patients with severe forms of the disease. This randomized, open-label, controlled, phase III trial assessed the efficacy of chloroquine or hydroxychloroquine for five days in combination with standard care compared to standard care alone in patients hospitalized with severe COVID-19. Chloroquine 450 mg BID on day 1 and 450 mg once daily from days 2 to 5 or hydroxychloroquine 400 mg BID on day 1 and 400 mg once daily from days 2 to 5 were administered in the intervention group. Patients were enrolled from April 16 to August 06, 2020, in 6 hospitals in southern Brazil. The primary outcome was the clinical status measured on day 14 after randomization with a 9-point ordinal scale. The main secondary outcomes were all-cause mortality; invasive mechanical ventilation use; the incidence of acute renal dysfunction in 28 days; and the clinical status of patients on days 5, 7, 10 and 28. All patients with a positive RT-PCR result for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were analyzed (modified intention to treat (mITT) population). Arrythmias and cardiovascular complications were assessed as safety outcomes. A total of 105 patients were enrolled and followed for 28 days. The trial was stopped before reaching the planned sample size due to harmful effects. Patients in the intervention group had a worse clinical outcome on the 14th day (odds ratio (OR) 2.45 [1.17 to 4.93], p = 0.016) and on the 28th day (OR 2.47 [1.15 to 5.30], p = 0.020). Moreover, the intervention group had higher incidences of invasive mechanical ventilation use (risk ratio (RR) 2.15 [1.05 to 4.40], p = 0.030) and severe renal dysfunction (KDIGO stage 3) (RR 2.24 [1.01 to 4.99], p = 0.042) until the 28th day of follow-up. No significant arrythmia was noted. In patients with severe COVID-19, the use of chloroquine/hydroxychloroquine added to standard treatment resulted in a significant worsening of clinical status, an increased risk of renal dysfunction and an increased need for invasive mechanical ventilation.Trial Registration: ClinicalTrials.gov, NCT04420247.

Application of the refinements of ICF linking rules to the Visual Analogue Scale, Roland Morris questionnaire and SF-36. / Aplicação do refinamento das regras de ligação da CIF à Escala Visual Analógica e aos questionários Roland Morris e SF-36.

The Visual Analogue Scale (VAS), Roland Morris Disability Questionnaire (RMDQ), Short Form Health Survey (SF-36) are broadly used and had their content linked to ICF by the linking rules of 2002 and 2005. In 2016 were refined and were not applied yet. To apply the refinements of ICF linking rules to VAS, RMDQ, and SF-36. Two health professionals identified the meaningful concepts and linked to the most precise ICF categories and a third triggered in divergences. The degree of agreement was calculated by kappa statistic. There was almost perfect agreement (Kappa=0.93 p<0,001). The main concept of VAS was linked to ICF category b280, the 24 main concepts of RMDQ linked to b28013, and 27 additional linked to other categories. The SF-36 had 36 main concepts and 30 additional concepts identified which 27 were definable by the ICF and 17 do not. From the total of ICF linked concepts, 39 refer to Body Functions, 57 to Activities and Participation and 4 to Environmental Factors. The refinements of linking rules propitiated more clarity in the process to identify, to link instruments content with ICF and to expose the results. Thus, increased the number of identified and linked concepts as well as the categories in the instruments.

A Escala Visual Analógica (EVA), o Questionário de Incapacidade de Roland Morris (RMDQ) e Questionário de Qualidade de Vida SF-36, amplamente utilizados, tiveram seu conteúdo conectado à CIF por regras propostas em 2002 e 2005. Em 2016 foram refinadas e ainda não foram aplicadas. Aplicar as regras de conexão de conteúdo refinadas para os instrumentos EVA, RMDQ e SF-36. Dois profissionais de saúde identificaram os conceitos significativos e vincularam às categorias mais específicas da CIF, um terceiro arbitrou divergências. O grau de concordância foi dado pelo coeficiente kappa. Houve alto grau de concordância (Kappa=0,93 p<0,001). O conceito principal da EVA foi conectado à categoria b280, os 24 conceitos principais do RMDQ, à categoria b28013 e os 27 adicionais a outras categorias. O SF-36 teve 36 conceitos principais e 30 adicionais identificados, do total, 17 não foram definíveis pela CIF. Dos conceitos conectados dos 3 instrumentos 39 referem-se à Funções do Corpo, 57 à Atividades e Participação e 4 à Fatores Ambientais. O refinamento das regras propiciou mais clareza no processo de identificar, relacionar o conteúdo dos instrumentos à CIF e expor os resultado e aumentou o número de conceitos identificados e categorias contempladas pelos instrumentos.

RESUMO A prática clínica tem sido subsidiada por instrumentos que permitem acessar e registrar informações de funcionalidade e saúde dos indivíduos. Uma forma de conhecer qual conteúdo da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) os instrumentos contemplam é usá-la como referência para auxiliar o profissional na escolha do mais adequado para acessar informações biopsicossociais. O objetivo foi identificar instrumentos da prática clínica em saúde que tiveram seu conteúdo ligado com a CIF e a existência de versão na língua portuguesa deles. Para tanto foi realizada uma revisão sistemática nas bases de dados SciELO Brasil, Lilacs e PubMed com os descritores "CIF", "questionário" e "regra de ligação" em português e inglês. Três pesquisadores independentes realizaram a seleção, e o nível de concordância foi obtido pelo coeficiente Kappa. Os critérios de elegibilidade foram: estudos primários de ligação de conteúdo de questionários, escalas, índices e checklists com a CIF publicados após 2001 em língua portuguesa ou inglesa. Foram incluídos 61 artigos, sendo 19 de origem brasileira. Dos 250 instrumentos ligados à CIF, 158 (63,2%) apresentaram versão em português sendo que dos 37 que mais se repetiram nos estudos, dois não apresentam essa versão. O coeficiente Kappa mostrou concordância entre moderada e boa (p<0,001). Este estudo apresentou um panorama da ligação de conteúdo de instrumentos da prática clínica à CIF identificando quais têm versão em língua portuguesa, o que contribuirá para o potencial fortalecimento da abordagem biopsicossocial dos profissionais de saúde.

RESUMEN La práctica clínica ha sido subsidiada por instrumentos que permiten acceder y registrar informaciones de funcionalidad y salud de los individuos. Una forma de conocer qué contenidos de la Clasificación Internacional de Funcionalidad, Incapacidad y Salud (CIF) los instrumentos contemplan es usarla como referencia para auxiliar al profesional en la elección del más adecuado para acceder a informaciones biopsicosociales. Lo objetivo fue identificar los instrumentos de la práctica clínica en la salud que tuviesen su contenido vinculado con el CIF y la disponibilidad de la versión en el idioma portugués. Para ello se realizó una revisión sistemática en las bases de datos SciELO Brasil, Lilacs y PubMed con las palabras clave "CIF", "cuestionario" y "reglas de vinculación "en portugués e inglés. Tres investigadores independientes realizaron la selección, y el nivel de concordancia fue obtenido por el coeficiente Kappa. Los criterios de elegibilidad fueron: estudios primarios de vinculación del contenido de cuestionarios, escalas, índices y listas de control con CIF publicados después de 2001 en el idioma portugués o Ingles. Fueron incluidos 61 artículos, siendo 19 de origen brasilero. De los 250 instrumentos con contenido relacionado a CIF, 158 (63,2%) presentaron versión en portugués, siendo que de los 37 que más se repitieron en los estudios dos no presentaron esta versión. El coeficiente Kappa mostró concordancia entre moderada y buena (p <0,001). Se ha delineado un panorama de la vinculación del contenido de instrumentos de la práctica clínica a la CIF identificando cuáles tienen versión en la lengua portuguesa y su potencial fortalecimiento del enfoque biopsicosocial.

ABSTRACT Clinical practice has been subsidized by instruments that record and allow access to information on functionality and health of individuals. One way to approach the content of the International Classification of Functioning, Disability and Health (ICF) is to use it as a reference to aid the professional in choosing the most appropriate instrument to access biopsychosocial information. We intend to identify health assessment instruments that had their content linked to the contents of the ICF and the presence of the Portuguese version of them. A systematic review was conducted of the SciELO Brazil, Lilacs and PubMed databases with the descriptors "ICF", "questionnaire" and "linking rules" in Portuguese and English. Three independent researchers performed the papers' selection, and the level of agreement was obtained by the kappa coefficient. The eligibility criteria were primary studies for questionnaires, scales, indices and checklists content linking to ICF published after 2001 in Portuguese or English. A total of 61 articles were included, of which 19 were of Brazilian origin. Given the totality of 250 instruments with ICF-related content, 158 (63.2%) presented a Portuguese-language version; just two of the 37 most cited works presented a Portuguese version. The Kappa coefficient showed significative agreement between moderate and good. This study provided an overview of the content connection between clinical practice instruments to ICF, identifying which instruments have Portuguese translation and its potential for strengthening the biopsychosocial approach.

Effects of Kinesio Taping on postural balance in patients with low back pain, a randomized controlled trial.

PURPOSE: to identify postural balance changes in subjects with low back pain after the application of Kinesio Taping, which is then compared to a no treatment control group, using baropodometric evaluation. METHODS: This randomized controlled trial was carried out on 50 individuals (both sexes) with chronic low back pain. They were then randomized into two groups: an experimental group - EG (treated with Kinesio Taping in the lumbar region) and a control group - CG (no intervention). Both groups underwent a baropodometric evaluation (mean plantar pressure, peak plantar pressure, plantar surface, mass distribution on right foot and left foot, mass distribution on forefoot and rear foot and base width) at four different moments: pre-intervention, 10 minutes, 48 hours, and 10 days after the intervention on the EG. The level of statistical significance was established at 5%. RESULTS: Significant changes were observed in the EG compared to the CG. In the EG, peak pressure reduced on both right and left foot after Kinesio Taping application; the right base width was reduced, and the mass distribution between the forefoot and the rear foot normalized towards the ideal 50% distribution. These changes happened 48 hours after the Kinesio Taping application, with effects lasting up to 10 days. CONCLUSION: The use of Kinesio Taping in the lumbar region of subjects with chronic low back pain improved postural balance. This is proved by changes in peak plantar pressure, plantar surface, and mass distribution 48 h after Kinesio Taping application, with effects lasting up to 10 days.
