SUMMARY OBJECTIVE: In-hospital cardiac arrest is a critical medical emergency. Knowledge of prognostic factors could assist in cardiopulmonary resuscitation decision-making. Frailty and functional status are emerging risk factors and may play a role in prognostication. The objective was to evaluate the association between reduced mobility and in-hospital cardiac arrest outcomes. METHODS: This retrospective cohort study included patients over 18 years of age with in-hospital cardiac arrest in Botucatu, Brazil, from April 2018 to December 2021. Exclusion criteria were patients with a do-not-resuscitate order or patients with recurrent in-hospital cardiac arrest. Reduced mobility was defined as the need for a bed bath 48 h before in-hospital cardiac arrest. The outcomes of no return of spontaneous circulation and in-hospital mortality were evaluated. RESULTS: A total of 387 patients were included in the analysis. The mean age was 65.4±14.8 years; 53.7% were males and 75.4% had reduced mobility. Among the evaluated outcomes, the no return of spontaneous circulation rate was 57.1%, and in-hospital mortality was 94.3%. In multivariate analysis, reduced mobility was associated with no return of spontaneous circulation when adjusted by age, gender, initial shockable rhythm, duration of cardiopulmonary resuscitation, and epinephrine administration. However, in multiple logistic regression, there was no association between reduced mobility and in-hospital mortality. CONCLUSION: In patients with in-hospital cardiac arrest, reduced mobility is associated with no return of spontaneous circulation. However, there is no relation to in-hospital mortality.

RESUMO OBJETIVO: Avaliar a concentração da peptidilarginina deiminase 4 (PAD4) e os polimorfismos de PADI4, como preditores de desenvolvimento de lesão renal aguda, necessidade de terapia renal substitutiva (TRS) e mortalidade em pacientes com choque séptico. MÉTODOS: Foram incluídos indivíduos com idade ≥18 anos, com diagnóstico de choque séptico na admissão na Unidade de Terapia Intensiva (UTI). Amostras de sangue foram coletadas nas primeiras 24 horas após a admissão do paciente para determinar a concentração sérica de PAD4 e seus polimorfismos PADI4 (rs11203367) e (rs874881). Os pacientes foram acompanhados durante a internação na UTI e tiveram avaliados desenvolvimento da lesão renal aguda séptica (Sepsis-induced acute kidney injury - Saki), necessidade TRS e mortalidade. RESULTADOS: Foram avaliados 99 pacientes; 51,5% desenvolveram Saki e, desses, 21,5% necessitaram de TRS e 80% morreram na UTI. Não houve diferença entre a concentração de PAD4 (p=0,116) e seus polimorfismos rs11203367 (p=0,910) e rs874881 (p=0,769) entre os pacientes. No entanto, o PAD4 apresentou correlação positiva com a concentração plasmática de ureia (r=0,269; p=0,007) e creatinina (r=0,284; p=0,004). A concentração de PAD4 e os polimorfismos da PADI4 também não foram associados à TRS e à mortalidade em pacientes com Saki. CONCLUSÕES: A concentração de PAD4 e seus polimorfismos não foram associados ao desenvolvimento de Saki, à necessidade de TRS ou à mortalidade em pacientes com choque séptico. No entanto, as concentrações de PAD4 foram associadas às concentrações de creatinina e ureia nesses pacientes.

SUMMARY BACKGROUND: The aim of this study is to evaluate the peptidylarginine deiminase 4 (PAD 4) concentration and PADI4 polymorphisms as predictors of acute kidney injury (AKI) development, the need for renal replacement therapy (RRT), and mortality in patients with septic shock. METHODS: We included all individuals aged ≥ 18 years, with a diagnosis of septic shock at ICU admission. Blood samples were taken within the first 24 hours of the patient's admission to determine serum PAD4 concentration and its PADI4 polymorphism (rs11203367) and (rs874881). Patients were monitored during their ICU stay and the development of SAKI was evaluated. Among the patients in whom SAKI developed, mortality and the need for RRT were also evaluated. RESULTS: There were 99 patients, 51.5% of whom developed SAKI and of these, 21.5% needed RRT and 80% died in the ICU. There was no difference between PAD4 concentration (p = 0.116) and its polymorphisms rs11203367 (p = 0.910) and rs874881 (p = 0.769) in patients in whom SAKI did or did not develop. However, PAD4 had a positive correlation with plasma urea concentration (r = 0.269 and p = 0.007) and creatinine (r = 0.284 and p = 0.004). The PAD4 concentration and PADI4 polymorphisms were also not associated with RRT and with mortality in patients with SAKI. CONCLUSION: PAD4 concentration and its polymorphisms were not associated with SAKI development, the need for RRT, or mortality in patients with septic shock. However, PAD4 concentrations were associated with creatinine and urea levels in these patients.

RESUMO OBJETIVO Avaliar a performance do escore de risco de Framingham (ERF) e do escore proposto pela American College of Cardiology/American Heart Association (ER ACC/AHA) em predizer a mortalidade em pacientes dez anos após síndrome coronariana aguda (SCA). MÉTODOS Trata-se de um estudo de coorte retrospectivo que incluiu pacientes com idade ≥18 anos, com SCA, que estiveram internados na Unidade de Terapia Intensiva Coronariana (UTI) do Hospital das Clínicas de Botucatu, no período de janeiro de 2005 a dezembro de 2006. RESULTADOS Foram avaliados 447 pacientes. Destes, 118 foram excluídos, pois a mortalidade em dez anos não foi obtida. Logo, 329 pacientes com idade de 62,9±13,0 anos foram estudados. Dentre eles, 58,4% eram homens e 44,4% morreram no período de dez anos após a internação. A mediana do ERF foi de 16 (14-18)%, e do ER ACC/AHA foi 18,5 (9,1-31,6)%. Os pacientes que evoluíram a óbito apresentaram maiores valores dos escores. No entanto, quando classificamos os pacientes em alto risco cardiovascular, apenas o ER ACC/AHA foi associado com a mortalidade (p<0,001). Na análise de regressão logística, ambos os escores foram associados com a mortalidade em dez anos (p<0,001). CONCLUSÕES Tanto o ERF quanto o ER ACC/AHA foram associados com a mortalidade. No entanto, para os pacientes classificados como alto risco, apenas o ER ACC/AHA foi associado com a mortalidade em dez anos.

SUMMARY BACKGROUND The objective of this study was to evaluate the performance of the Framingham risk score (FRS) and risk score by the American College of Cardiology/American Heart Association (SR ACC/AHA) in predicting mortality of patients ten years after acute coronary syndrome (ACS). METHODS This is a retrospective cohort study that included patients aged ≥ 18 years with ACS who were hospitalized at the Coronary Intensive Care Unit (ICU) of the Botucatu Medical School Hospital from January 2005 to December of 2006. RESULTS A total of 447 patients were evaluated. Of these, 118 were excluded because the mortality in 10 years was not obtained. Thus, 329 patients aged 62.9 ± 13.0 years were studied. Among them, 58.4% were men, and 44.4% died within ten years of hospitalization. The median FRS was 16 (14-18) %, and the ACC/AHA RS was 18.5 (9.1-31.6). Patients who died had higher values of both scores. However, when we classified patients at high cardiovascular risk, only the ACC/AHA RS was associated with mortality (p <0.001). In the logistic regression analysis, both scores were associated with mortality at ten years (p <0.001). CONCLUSIONS Both FRS and SR ACC/AHA were associated with mortality. However, for patients classified as high risk, only the ACC/AHA RS was associated with mortality within ten years.

RESUMO Acidentes vasculares cerebrais (AVC) embólicos de fonte indeterminada (ESUS) é um grupo importante de pacientes com AVC criptogênico que estão em evidência devido a recentes ensaios clínicos. Foram revisados os prontuários médicos na alta da unidade de AVC de todos os pacientes que preencheram os critérios para ESUS atendidos em nossa instituição entre fevereiro de 2016 e julho de 2017. Entre 550 AVCs, 51 eram pacientes com ESUS. Hipertensão (60%), diabetes mellitus (34%) e tabagismo (36%) foram os fatores de risco mais prevalentes. Os escores médios do National Institutes of Health Stroke Scale (NIHSS) foram 7 na admissão e 4 na alta, enquanto os escores médios na escala de Rankin modificada (mRs) foram 0 e 2 na admissão e alta, respectivamente. Nossa amostra teve idade, prevalência de fatores de risco, escores NIHSS na admissão e alta, quando comparados com coortes europeias e norte-americanas semelhantes. Apesar de ser uma pequena coorte, nosso estudo sugere que a população ESUS é semelhante em países com diferentes níveis de financiamento em saúde.

ABSTRACT Embolic stroke of undetermined source (ESUS) is an important group of cryptogenic strokes that are in evidence due recent ongoing trials. We reviewed medical records at discharge from the stroke unit of all patients who met ESUS criteria and attended our institution between February 2016 and July 2017. Among 550 stroke patients, 51 had ESUS. We found that hypertension (60%), diabetes mellitus (34%), and smoking (36%) were the most prevalent risk factors. The mean National Institutes of Health Stroke Scale (NIHSS) scores were 7 at admission and 4 at discharge, while median scores on the modified Rankin scale were 0 and 2 at admission and discharge, respectively. Our sample had similar ages, risk factors prevalence and NIHSS scores at admission and discharge when compared with European and North American cohorts. Although a small cohort, our study suggests that the ESUS population is similar in countries with different health financing.

Resumo Introdução: Apesar da diminuição da mortalidade por infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAM-ST) no mundo, a doença ainda acarreta elevados custos e morbidade. Muitas medidas contribuem para a redução da mortalidade, dentre elas a criação de unidades intensivas coronarianas (UCO). Objetivo: Avaliar o impacto da criação de uma UCO na prescrição de tratamentos preconizados e na mortalidade em 30 dias em pacientes com IAM-ST. Método: Foi realizado estudo retrospectivo e foram coletados dados de prontuários de pacientes internados na UCO de 2005 a 2006 (grupo depois). Esses dados foram comparados com dados do serviço de 2000 a 2002, previamente à criação da UCO (grupo antes). Resultados: Havia 101 e 143 pacientes nos grupos depois e antes, respectivamente. Não houve diferenças em relação às características populacionais e às características do infarto entre os períodos. Observamos aumento na prescrição de iECA, clopidogrel e estatinas. Apesar da ausência de mudanças no número de pacientes que receberam terapia de reperfusão, houve aumento de angioplastias primárias em detrimento ao uso de trombolíticos no período posterior à criação da UCO. Não observamos diminuição da mortalidade em 30 dias após IAM-ST (antes: 10,5%; depois: 8,9%; p=0,850), mas a prescrição de tratamentos preconizados foi alta em ambos os períodos. O uso de iECA e de betabloqueador diminuiu o risco de morte em 4,4 e 4,9 vezes, respectivamente. Conclusão: Em pacientes com IAM-ST, a criação da UCO não reduziu a mortalidade em 30 dias, mas houve aumento na prescrição de tratamentos preconizados.

Summary Introduction: The mortality rate attributed to ST-segment elevation myocardial infarction (STEMI) has decreased in the world. However, this disease is still responsible for high costs for health systems. Several factors could decrease mortality in these patients, including implementation of cardiac intensive care units (CICU). The aim of this study was to evaluate the effect of CICU implementation on prescribed recommended treatments and mortality 30 days after STEMI. Method: We performed a retrospective study with patients admitted to CICU between 2005 and 2006 (after group) and between 2000 and 2002, before CICU implementation (before group). Results: The after group had 101 patients, while the before group had 143 patients. There were no differences in general characteristics between groups. We observed an increase in angiotensin-converting enzyme inhibitors, clopidogrel and statin prescriptions after CICU implementation. We did not find differences regarding number of patients submitted to reperfusion therapy; however, there was an increase in primary percutaneous angioplasty compared with thrombolytic therapy in the after group. There was no difference in 30-day mortality (before: 10.5%; after: 8.9%; p=0.850), but prescription of recommended treatments was high in both groups. Prescription of angiotensin-converting enzyme inhibitors and beta-blocker decreased mortality risk by 4.4 and 4.9 times, respectively. Conclusion: CICU implementation did not reduce mortality after 30 days in patients with STEMI; however, it increased the prescription of standard treatment for these patients.
