Predictive Value of Myocardial injury in Patients with COVID-19 Admitted to a Quaternary Hospital in the City of Rio de Janeiro

Abstract Background In Brazil the factors involved in the risk of death in patients with COVID-19 have not been well established. Objective To analyze whether elevations of high-sensitivity troponin I (hTnI) levels influence the mortality of patients with COVID-19. Methods Clinical and laboratory characteristics of hospitalized patients with COVID-19 were collected upon hospital admission. Univariate and binary logistic regression analyzes were performed to assess the factors that influence mortality. P-value<0.05 was considered significant. Results This study analyzed192 patients who received hospital admission between March 16 and June 2, 2020 and who were discharged or died by July 2, 2020. The mean age was 70±15 years, 80 (41.7%) of whom were women. In comparison to those who were discharged, the 54 (28.1%) who died were older (79±12 vs 66±15years; P=0.004), and with a higher Charlson´s index (5±2 vs 3±2; P=0.027). More patients, aged≥60years (P <0.0001), Charlson´s index>1 (P=0.004), lung injury>50% in chest computed tomography (P=0.011), with previous coronary artery disease (P=0.037), hypertension (P=0.033), stroke (P=0.008), heart failure (P=0.002), lymphocytopenia (P=0.024), high D-dimer (P=0.024), high INR (P=0.003), hTnI (P<0.0001), high creatinine (P<0.0001), invasive mechanical ventilation (P<0.0001), renal replacement therapy (P<0.0001), vasoactive amine (P<0.0001), and transfer to the ICU (P=0.001), died when compared to those who were discharged. In logistic regression analysis, elevated hTnI levels (OR=9.504; 95% CI=1.281-70.528; P=0.028) upon admission, and the need for mechanical ventilation during hospitalization (OR=46.691; 95% CI=2.360-923.706; P=0.012) increased the chance of in-hospital mortality. Conclusion This study suggests that in COVID-19 disease, myocardial injury upon hospital admission is a harbinger of poor prognosis.

O exercício físico funcional para idosos institucionalizados: um novo olhar para as atividades da vida diária / The functional exercise for older institutionalized: a new look at the activities of daily living

A expectativa de vida do ser humano tem alcançado marcas elevadas em função da evolução de vários benefícios para sua qualidade de vida. Isso faz com que o quadro geral de idosos aumente substancialmente. Vários profissionais da saúde, nas suas especializações, desenvolvem recursos para a manutenção de uma vida mais saudável para esses idosos. O profissional de Educação Física contribui especificamente no desempenho das habilidades motoras. Porém, percebeu-se que os estudos sobre o desenvolvimento de atividades físicas para idosos institucionalizados em casas de acolhimento não estão acompanhando o desenvolvimento em outros espaços dessa área de conhecimento. Essa defasagem é causada pelas dificuldades de lidar com esse idoso; pelos paradigmas fundamentais que orientam as ações intervencionistas do profissional; pela inatividade decorrente das políticas públicas voltadas para grupo social, dentre outras. Fica evidente a caracterização de um problema no qual se percebe que idosos são “depositados” em um local à espera de seu fim. Nesse sentido, este estudo propôs verificar se a prática de movimento corporal, baseada no exercício físico funcional, pode provocar melhoras na autoestima e, consequentemente, na qualidade de vida desse idoso institucionalizado. Os resultados foram levantados por meio de uma pesquisa qualitativa descritiva. Os idosos responderam à prática do exercício sistemático e apontaram indicadores interessantes para melhoria de ações nas suas vidas diárias.(AU)

The life expectancy of human beings has achieved high marks in the light of various benefits to their quality of life. This makes the overall picture of elderly will increase substantially. Several health professionals in their specializations develop resources for maintaining a healthy life for these seniors. The Physical Education professional contributes specifically in the performance of motor skills. However, it was noted that studies on the development of physical activities for the institutionalized elderly in shelters are not watching the developments in other areas of this field. This gap is caused by the difficulties of dealing with this elderly; fundamental paradigms that guide the actions of professional interventionists; inactivity caused by public policies aimed at social group, among others. It is evident characterization of a problem in which one realizes that seniors are “deposited” in a place waiting for your order. Thus, this study aimed to verify whether the practice of body movement, based on functional exercise may cause improvements in self-esteem and consequently the quality of life of institutionalized elderly. The results were collected through a descriptive qualitative research. The seniors responded to the practice of systematic and interesting indicators pointed to improvement actions in their daily lives.(AU)

Central venous saturation: a prognostic tool in cardiac surgery patients.

BACKGROUND: Central venous oxygen saturation (ScvO(2)) is a valuable prognostic marker in sepsis. However, its value in cardiac surgery has not been assessed yet. This study aimed at evaluating ScvO(2) as a tool for predicting short-term organ dysfunction (OD) after cardiac surgery. METHODS: A prospective cohort including cardiac surgery patients submitted to a goal-oriented therapy to maintain ScvO(2) above 70% was studied. Postoperative blood samples collected at 30 minutes (T1), 6 hours (T2), and 24 hours (T3) for ScvO(2) measurement were selected to further analysis. Two groups were formed according to the absence (G0) or presence (G1) of OD defined as a Sequential Organ Failure Assessment (SOFA) score >or=5 on the third postoperative day. A logistic regression analysis was performed to identify the variables independently associated with OD on the third postoperative day. RESULTS: From the 246 patients included, 54 (22%) developed OD and were defined as G1. The mortality rates in G0 and G1 were 1.6% and 31.5%, respectively (P < .001). In the comparative analysis between G0 and G1, the ScvO(2) values were remarkably lower in G1 at T1 (66.2 +/- 9.2 vs 62.3 +/- 11.6; P = .009), T2 (69.6 +/- 5.9 vs 63.5 +/- 9.4; P

Adult extracorporeal life support: a failed or forgotten concept?

BACKGROUND: The extracorporeal membrane oxygenation (ECMO) has been used in the neonatal and childhood periods with excellent results. The adult experience has been modest with inferior immediate results. The intermediate survival, however, has been promising. We have been using the extracorporeal membrane oxygenation for temporary mechanical circulatory support of adults that present with acute refractory cardiogenic shock in our institution. There is no other published experience of the use of this system in this scenario in Brazil. OBJECTIVE: To describe our experience with the use of the extracorporeal membrane oxygenation for circulatory support in adults. METHODS: Retrospective analysis of the medical files of patients submitted to the implant of extracorporeal membrane oxygenation system for circulatory assistance in acute and refractory cardiogenic shock. RESULTS: Eleven patients (63,5 yo; 45,5% male) were considered for analysis from 2005 to 2007. Median support time was 77 hours (10-240 h) and 5 patients have survived 30 days (45,5%). Two patients were subsequently submitted to prolonged paracorporeal circulatory assistance. Mortality on ECMO (6 patients) was due to multiple organ failure (66,6%) and refractory bleeding (33,4%). CONCLUSION: ECMO system is an option to be used in acute refractory cardiogenic shock as a bridge to recovery or selecting patients that might benefit from prolonged paracorporeal assist devices (bridge to bridge).

Assistência circulatória com oxigenação por membrana extracorpórea (ECMO) no adulto: um conceito falido ou esquecido? / Adult extracorporeal life support: a failed or forgotten concept?

FUNDAMENTO: A oxigenação por membrana extracorpórea (ECMO) em recém-nascidos e crianças tem resultados excelentes. A experiência em adultos é mais modesta e os resultados imediatos são inferiores. Entretanto, a sobrevida em cinco anos de pacientes que sobrevivem a esse método é bastante promissora. Não há relato na literatura brasileira de experiências com esse sistema nesse contexto. OBJETIVO: Relatar a experiência com o uso da oxigenação por membrana extracorpórea no adulto que se apresenta em choque cardiogênico agudo e refratário. MÉTODOS: Análise retrospectiva de prontuários médicos de pacientes submetidos a implante do sistema de oxigenação por membrana extracorpórea para a assistência circulatória no choque cardiogênico agudo e refratário. RESULTADOS: Onze pacientes (63,5 anos; 45,5 por cento homens) foram considerados para análise no período de 2005 a 2007. O tempo médio de suporte circulatório foi de 77 horas (10-240h) e cinco pacientes estavam vivos em 30 dias (45,5 por cento). Dois pacientes foram subseqüentemente submetidos a implante de assistência circulatória prolongada após um período de ressuscitação em ECMO, um dos quais foi submetido ao transplante cardíaco. As causas de morte durante a assistência com ECMO (seis pacientes) incluíram falência multiorgânica (66,6 por cento) ou sangramento refratário (33,4 por cento). CONCLUSÃO: O sistema ECMO é uma opção de assistência circulatória temporária para pacientes adultos com falência cardíaca aguda refratária, podendo ser utilizado como ponte para a recuperação ou com o intuito de selecionar candidatos à assistência circulatória prolongada (ponte para a ponte).

Indicators of healthcare quality in isolated coronary artery bypass graft surgery performed at a tertiary cardiology center.

BACKGROUND: Quality indicators (QI) for cardiac surgery are important instruments for measuring healthcare quality in hospital centers and allow comparison with high-quality healthcare centers. OBJECTIVE: To evaluate QIs in isolated myocardial revascularization procedures (CABG) performed at a tertiary cardiology center. METHODS: One hundred and forty-four consecutive patients who had undergone isolated CABG were evaluated between October 2005 and March 2007. One hundred and eight patients were men (75%), the mean age was 65+/-11, and the EuroSCORE was 4+/-3. The following QIs were measured: time elapsed between the surgery date-setting appointment and the actual day of the CABG (TDC); surgery cancellation rate (SCR) due to problems in hospital infrastructure; length of hospital stay (LOS); operative mortality (OM) and rate of readmission (RHR) for infection in the surgical wound. RESULTS: The TDC (n=98) was 4+/-3 days (median: 4 days) and the SCR was zero. The OM recorded of 4.9% (95% confidence interval [CI] = 2.2 - 9.87%) was lower than the expected OM of 5.1% (95% CI = 1.4% to 14.37%), but with no statistical significance (p=0.65). The area under the ROC curve of the EuroSCORE for the OM was 0.702 (95% CI = 0.485 - 0.919). LOS was 11+/-9 days. The area under the ROC curve of the EuroSCORE for the LOS was 0.764 (95% CI = 0.675 - 0.852). The RHR recorded was 2.1%. CONCLUSION: The measurement of the QIs showed that, in a medical center with a low annual volume of CABG, the results were compatible with the risk profile of the population involved.

Indicadores de qualidade assistencial na cirurgia de revascularização miocárdica isolada em centro cardiológico terciário / Indicators of healthcare quality in isolated coronary artery bypass graft surgery performed at a tertiary cardiology center

FUNDAMENTO: Indicadores de qualidade (IQ) em cirurgia cardíaca são importantes instrumentos de avaliação da assistência médica em centros hospitalares. OBJETIVO: Avaliar os IQ da cirurgia de revascularização miocárdica (CRVM) isolada em centro terciário cardiológico. MÉTODOS: Foram avaliados 144 pacientes consecutivos submetidos a CRVM isolada entre outubro de 2005 e março de 2007: 108 pacientes eram do sexo masculino (75 por cento), com média de idade de 65±11 anos e EuroSCORE de 4±3. Os IQ avaliados foram: intervalo de tempo entre a marcação e a realização da cirurgia (TMC); taxa de cancelamento (TxC) decorrentes de problemas ligados à infra-estrutura hospitalar; tempo de permanência hospitalar (TPH); mortalidade operatória (MO) e taxa de reinternação hospitalar por infecção em ferida cirúrgica (TxRH). RESULTADOS: O TMC (n=98) foi de 4±3 dias (mediana de 4 dias) e a TxC foi zero. A MO observada de 4,9 por cento (Intervalo de Confiança [IC] 95 por cento = 2,2 - 9,87 por cento) foi menor do que a MO esperada de 5,1 por cento (IC 95 por cento = 1,4 por cento a 14,37 por cento), mas sem significância estatística (p=0,65). A área sob a curva ROC do EuroSCORE para MO observada foi de 0,702 (IC 95 por cento = 0,485 - 0,919). O TPH foi de 11±9 dias. A área sob a curva ROC do EuroSCORE para TPH foi de 0,764 (IC 95 por cento = 0,675 - 0,852). A TxRH observada foi de 2,1 por cento. CONCLUSÃO: A avaliação dos IQ demonstrou que, em um centro com baixo número anual de CRVM, os resultados alcançados foram compatíveis com o perfil de risco da população envolvida.

O edema agudo de pulmão do tipo cardiogênico é o mais comum na sala de emergência. Tem entre as suas causas mais freqüentes a isquemia do miocárdio, arritmias cardíacas, hipertensão arterial e doença valvular. O quadro clínico inclui taquidispnéia, tosse com expectoração rósea e espumosa, sinais de esforço respiratório e cianose. O diagnóstico e a abordagem terapêutica precoce do quadro são fundamentais para reduzir a morbidade e a mortalidade.

Circulating inflammatory mediators and organ dysfunction after cardiovascular surgery with cardiopulmonary bypass: a prospective observational study.

INTRODUCTION: Cardiovascular surgery with cardiopulmonary bypass (CPB) has improved in past decades, but inflammatory activation in this setting is still unpredictable and is associated with several postoperative complications. Perioperative levels of macrophage migration inhibitory factor (MIF) and other inflammatory mediators could be implicated in adverse outcomes in cardiac surgery. METHODS: Serum levels of MIF, monocyte chemoattractant protein (MCP)-1, soluble CD40 ligand, IL-6 and IL-10 from 93 patients subjected to CPB were measured by enzyme-linked immunosorbent assay and compared with specific and global postoperative organ dysfunctions through multiple organ dysfunction score (MODS) and sequential organ failure assessment (SOFA). RESULTS: Most of the cytokines measured had a peak of production between 3 and 6 hours after CPB, but maximum levels of MIF occurred earlier, at the cessation of CPB. Among specific organ dysfunctions, the most frequent was hematological, occurring in 82% of the patients. Circulatory impairment was observed in 73.1% of the patients, and 51% of these needed inotropics or vasopressors within the first 24 hours after surgery. The third most frequent dysfunction was pulmonary, occurring in 48.4% of the patients. Preoperative levels of MIF showed a relevant direct correlation with the intensity of global organ dysfunction measured by SOFA (rho = 0.46, p < 0.001) and MODS (rho = 0.50, p < 0.001) on the third day after surgery. MCP-1 production was associated with postoperative thrombocytopenia, and MIF was related to the use of a high dose of vasopressors in patients with cardiovascular impairment and also to lower values of the ratio of partial arterial oxygen tension (PaO2) to fraction of inspired oxygen (FiO2) registered in the first 24 hours after CPB. CONCLUSION: Despite the multifactorial nature of specific or multiple organ dysfunctions, MIF should be explored as a predicting factor of organ dysfunction, or even as a potential therapeutic target in decreasing postoperative complications.
