Characteristics and risk factors for 28-day mortality of hospital acquired fungemias in ICUs: data from the EUROBACT study.

BACKGROUND: To characterize and identify prognostic factors for 28-day mortality among patients with hospital-acquired fungemia (HAF) in the Intensive Care Unit (ICU). METHODS: A sub-analysis of a prospective, multicenter non-representative cohort study conducted in 162 ICUs in 24 countries. RESULTS: Of the 1156 patients with hospital-acquired bloodstream infections (HA-BSI) included in the EUROBACT study, 96 patients had a HAF. Median time to its diagnosis was 20 days (IQR 10.5-30.5) and 9 days (IQR 3-15.5) after hospital and ICU admission, respectively. Median time to positivity of blood culture was longer in fungemia than in bacteremia (48.7 h vs. 38.1 h; p = 0.0004). Candida albicans was the most frequent fungus isolated (57.1%), followed by Candida glabrata (15.3%) and Candida parapsilosis (10.2%). No clear source of HAF was detected in 33.3% of the episodes and it was catheter-related in 21.9% of them. Compared to patients with bacteremia, HAF patients had a higher rate of septic shock (39.6% vs. 21.6%; p = 0.0003) and renal dysfunction (25% vs. 12.4%; p = 0.0023) on admission and a higher rate of renal failure (26% vs. 16.2%; p = 0.0273) at diagnosis. Adequate treatment started within 24 h after blood culture collection was less frequent in HAF patients (22.9% vs. 55.3%; p < 0.001). The 28-day all cause fatality was 40.6%. According to multivariate analysis, only liver failure (OR 14.35; 95% CI 1.17-175.6; p = 0.037), need for mechanical ventilation (OR 8.86; 95% CI 1.2-65.24; p = 0.032) and ICU admission for medical reason (OR 3.87; 95% CI 1.25-11.99; p = 0.020) were independent predictors of 28-day mortality in HAF patients. CONCLUSIONS: Fungi are an important cause of hospital-acquired BSI in the ICU. Patients with HAF present more frequently with septic shock and renal dysfunction on ICU admission and have a higher rate of renal failure at diagnosis. HAF are associated with a significant 28-day mortality rate (40%), but delayed adequate antifungal therapy was not an independent risk factor for death. Liver failure, need for mechanical ventilation and ICU admission for medical reason were the only independent predictors of 28-day mortality.

Early sedation and clinical outcomes of mechanically ventilated patients: a prospective multicenter cohort study.

INTRODUCTION: Sedation overuse is frequent and possibly associated with poor outcomes in the intensive care unit (ICU) patients. However, the association of early oversedation with clinical outcomes has not been thoroughly evaluated. The aim of this study was to assess the association of early sedation strategies with outcomes of critically ill adult patients under mechanical ventilation (MV). METHODS: A secondary analysis of a multicenter prospective cohort conducted in 45 Brazilian ICUs, including adult patients requiring ventilatory support and sedation in the first 48 hours of ICU admissions, was performed. Sedation depth was evaluated after 48 hours of MV. Multivariate analysis was used to identify variables associated with hospital mortality. RESULTS: A total of 322 patients were evaluated. Overall, ICU and hospital mortality rates were 30.4% and 38.8%, respectively. Deep sedation was observed in 113 patients (35.1%). Longer duration of ventilatory support was observed (7 (4 to 10) versus 5 (3 to 9) days, P = 0.041) and more tracheostomies were performed in the deep sedation group (38.9% versus 22%, P = 0.001) despite similar PaO2/FiO2 ratios and acute respiratory distress syndrome (ARDS) severity. In a multivariate analysis, age (Odds Ratio (OR) 1.02; 95% confidence interval (CI) 1.00 to 1.03), Charlson Comorbidity Index >2 (OR 2.06; 95% CI, 1.44 to 2.94), Simplified Acute Physiology Score 3 (SAPS 3) score (OR 1.02; CI 95%, 1.00 to 1.04), severe ARDS (OR 1.44; CI 95%, 1.09 to 1.91) and deep sedation (OR 2.36; CI 95%, 1.31 to 4.25) were independently associated with increased hospital mortality. CONCLUSIONS: Early deep sedation is associated with adverse outcomes and constitutes an independent predictor of hospital mortality in mechanically ventilated patients.

Ascending Flaccid Paralysis Secondary to Hypokalemia in A Cancer Patient using Abiraterone - A Case Report.

BACKGROUND: Prostate cancer (PC) is the most common type of neoplasm in men and the fourth leading cause of mortality in Brazil. The prostate cancer refractory metastatic castration can be treated with abiraterone acetate (AA). CASE PRESENTATION: Its use has been associated with increased survival. However, there are also side effects associated with the use of this drug, such as severe electrolyte disturbances. CONCLUSION: The objective is to report the clinical case of a patient with castration-resistant metastatic prostate cancer who developed ascending flaccid paralysis secondary to severe hypokalemia, probably due to hyperaldosteronism secondary to the use of Abiraterone Acetate, despite the use of Prednisone.

Highly active antiretroviral therapy for critically ill HIV patients: A systematic review and meta-analysis.

INTRODUCTION: It is unclear whether the treatment of an HIV infection with highly active antiretroviral therapy (HAART) affects intensive care unit (ICU) outcomes. In this paper, we report the results of a systematic review and meta-analysis performed to summarize the effects of HAART on the prognosis of critically ill HIV positive patients. MATERIALS AND METHODS: A bibliographic search was performed in 3 databases (PubMed, Web of Science and Scopus) to identify articles that investigated the use of HAART during ICU admissions for short- and long-term mortality or survival. Eligible articles were selected in a staged process and were independently assessed by two investigators. The methodological quality of the selected articles was evaluated using the Methodological Index for Non-Randomized Studies (MINORS) tool. RESULTS: Twelve articles met the systematic review inclusion criteria and examined short-term mortality. Six of them also examined long-term mortality (≥90 days) after ICU discharge. The short-term mortality meta-analysis showed a significant beneficial effect of initiating or maintaining HAART during the ICU stay (random effects odds ratio 0.53, p = 0.02). The data analysis of long-term outcomes also suggested a reduced mortality when HAART was used, but the effect of HAART on long-term mortality of HIV positive critically ill patients remains uncertain. CONCLUSIONS: This meta-analysis suggests improved survival rates for HIV positive patients who were treated with HAART during their ICU admission.

Defining and treating acute kidney injury patients in Brazilian intensive care units: Results from a cross-sectional nationwide survey.

PURPOSE: The purpose of the study is to characterize the practices of Brazilian intensivists toward acute kidney injury (AKI) definition and management. METHODS: A cross-sectional survey was conducted among 36 Brazilian hospitals. RESULTS: Of 731 ICU physicians invited to participate, 310 (42%) responded to the survey. Nearly half of the intensive care unit (ICU) physicians (146/310) do not apply AKIN and/or RIFLE definitions to their ICU patients. Most of the respondents prescribe intravenous fluids as a first-line therapeutic intervention for AKI patients. Although 38% of the surveyed physicians considered worsening of respiratory parameters to be the main criterion for stopping fluid infusion, only 15% considered daily net fluid balance as a criterion. Most of the respondents believed in the benefits of early renal replacement therapy (RRT) and considered worsening acidosis the most important criteria for starting early RRT. The main reason for a nephrologist referral was an urgently needed RRT. CONCLUSIONS: Despite recent advances in AKI definition and management, most of the surveyed ICU physicians in Brazil have not incorporated them in their clinical practice. Important differences in the management of AKI patients were observed among Brazilian ICU physicians, which is relevant for educational interventions and future research.

Clinical Profiles and Factors Associated with Death in Adults with Dengue Admitted to Intensive Care Units, Minas Gerais, Brazil.

The purpose of our study was to describe the clinical profile of dengue-infected patients admitted to Brazilian intensive care units (ICU) and evaluate factors associated with death. A longitudinal, multicenter case series study was conducted with laboratory-confirmed dengue patients admitted to nine Brazilian ICUs situated in Minas Gerais state, southeastern Brazil from January 1, 2008, to December 31, 2013. Demographic, clinical and laboratory data; disease severity scores; and mortality were evaluated. A total of 97 patients were studied. The in-ICU and in-hospital mortality rates were 18.6% and 19.6%, respectively. Patients classified as having severe dengue according to current World Health Organization classifications showed an increased risk of death in a univariate analysis. Nonsurvivors were older, exhibited lower serum albumin concentrations and higher total leukocyte counts and serum creatinine levels. Other risk factors (vomiting, lethargy/restlessness, dyspnea/respiratory distress) were also associated with death in a univariate analysis. Multivariate analysis indicated that in-hospital mortality was significantly associated with Acute Physiology and Chronic Health Evaluation II and the Sequential Organ Failure Assessment score. The ICU and in-hospital mortality observed in this study were higher than values reported in similar studies. An increased frequency of ICU admission due to severe organ dysfunction, higher severity indices and scarcity of ICU beds may partially explain the higher mortality.

Revisão sistemática de fatores prognósticos a curto prazo de pacientes HIV internados em uma unidade de cuidados intensivos / Systematic review of short-term prognostic factors of HIV patients admitted to an intensive care unit

Conhecer os fatores prognósticos de curto prazo de pacientes HIV, criticamente doentes, na era de terapia antirretroviral combinada, é importante para adoção de medidas preventivas e mais efetivas de tratamento. Para identificar os fatores mais significativos e comuns que determinam a mortalidade a curto prazo, uma revisão sistemática da literatura mais relevante foi conduzida. Método: Uma busca na internet foi conduzida em 3 bases de dados de artigos científicos indexados (PubMed, Scopus e Web of Science) para estudos que investigaram fatores prognósticos de mortalidade ou sobrevivência a curto prazo (em UTIs, ou em outros setores do hospital, seguindo a internação na UTI) de pacientes HIV criticamente enfermos. Os artigos foram selecionados de acordo com critérios pré-estabelecidos e avaliados independentemente por 2 pesquisadores. As variáveis coletadas foram autor, ano, local e tipo do estudo, número de pacientes com HIV, mortalidade, fatores significativos em regressão logística simples e múltipla, principais causas de admissão e critérios de inclusão. Resultados: Vinte e seis artigos foram selecionados para revisão sistemática. Quinze lidaram com fatores que determinavam mortalidade na UTI, 9 com mortalidade hospitalar após internação em UTI, e 2 com ambos. Conclusões: Fatores associados à gravidade de doença aguda, como escores prognósticos, albumina e disfunção orgânica (choque e insuficiência respiratória) parecem ser mais importantes como determinantes da mortalidade a curto prazo que aqueles associados ao HIV.

Knowing the short-term prognostic factors of critically ill HIV patients admitted to intensive care units (ICUs) in the era of combination antiretroviral therapy (cART) is important for the adoption of preventive measures and more effective treatment. To identify the most significant and common factors that determine short-term mortality, a systematic review of the relevant literature was carried out. Method: An internet search was conducted in three databases indexing scientific articles (PubMed, Scopus, and Web of Science) for studies investigating the prognostic factors of mortality or short-term survival (in ICUs and elsewhere in hospitals following ICU admission) of critically ill HIV-infected patients. The articles were selected according to pre-established criteria and evaluated independently by two researchers. The variables collected were author, year, study location, study type, number of patients with HIV, mortality, significant factors in simple logistic regression and multiple regression, main causes of admission, and inclusion criteria. Results: Twenty-six articles were selected for systematic review. Fifteen dealt with factors that determine mortality in the ICU, nine with hospital mortality following ICU admission, and two with both. Conclusions: Factors associated with the severity of acute disease, such as prognostic scores, albumin, and organ failure (shock and respiratory failure), seem to be more important as determinants of short-term mortality than those associated with HIV

Guidelines for potential multiple organ donors (adult). Part III: organ-specific recommendations. / Diretrizes para manutenção de múltiplos órgãos no potencial doador adulto falecido: Parte III. Recomendações órgãos específicas.

Brain death (BD) alters the pathophysiology of patients and may damage the kidneys, the lungs, the heart and the liver. To obtain better quality transplant organs, intensive care physicians in charge of the maintenance of deceased donors should attentively monitor these organs. Careful hemodynamic, ventilatory and bronchial clearance management minimizes the loss of kidneys and lungs. The evaluation of cardiac function and morphology supports the transplant viability assessment of the heart. The monitoring of liver function, the management of the patient's metabolic status and the evaluation of viral serology are fundamental for organ selection by the transplant teams and for the care of the transplant recipient.

Diretrizes para avaliação e validação do potencial doador de órgãos em morte encefálica / Guidelines for the assessment and acceptance of potential brain-dead organ donors

RESUMO O transplante de órgãos é a única alternativa para muitos pacientes portadores de algumas doenças terminais. Ao mesmo tempo, é preocupante a crescente desproporção entre a alta demanda por transplantes de órgãos e o baixo índice de transplantes efetivados. Dentre as diferentes causas que alimentam essa desproporção, estão os equívocos na identificação do potencial doador de órgãos e as contraindicações mal atribuídas pela equipe assistente. Assim, o presente documento pretende fornecer subsídios à equipe multiprofissional da terapia intensiva para o reconhecimento, a avaliação e a validação do potencial doador de órgãos.

ABSTRACT Organ transplantation is the only alternative for many patients with terminal diseases. The increasing disproportion between the high demand for organ transplants and the low rate of transplants actually performed is worrisome. Some of the causes of this disproportion are errors in the identification of potential organ donors and in the determination of contraindications by the attending staff. Therefore, the aim of the present document is to provide guidelines for intensive care multi-professional staffs for the recognition, assessment and acceptance of potential organ donors.

Study of resuscitated in- and out-hospital cardiorespiratory arrest patients undergoing therapeutic hypothermia. / Estudo de pacientes reanimados pós-parada cardiorrespiratória intra e extra-hospitalar submetidos à hipotermia terapêutica.

OBJECTIVE: To determine the characteristics of patients undergoing standard institutional protocol for management of resuscitated patients after a cardiac arrest episode, including therapeutic hypothermia. METHODS: This was a retrospective analysis of 26 consecutive patients admitted following cardiac arrest, between January 2007 and November 2008. RESULTS: All cases underwent therapeutic hypothermia. Average age was 63 years, and the patients were predominantly male. Cardiac arrest event was out-of-hospital in 8 cases, in the emergency room in 3 cases, in the wards in 13 cases and in the operation room in 2 cases. The cardiac arrest rhythm was ventricular fibrillation in seven patients, asystolia in 11, pulseless electrical activity in 5 cases, and was undetermined in 3 patients. The interval between the cardiac arrest and return of spontaneous circulation was 12 minutes (SD ± 5 min). The time to reach the target temperature was 5 ± 4 hours, the hypothermia time was 22 ± 6 hours and time to rewarming 9 ± 5.9 hours. Fourteen patients died in the intensive care unit, a 54% mortality, and three patients died during the in-hospital stay, a 66% in-hospital mortality. There was statistically significant reduction in hemoglobin (p<0.001), leukocytes (p=0.001), platelets (p<0.001), lactate (p<0.001) and potassium (p=0.009), values and increased C reactive protein (p=0.001) and INR (p=0.004) after hypothermia. CONCLUSIONS: The creation of a standard operative protocol for therapeutic hypothermia in post cardiac arrest patients management resulted in a high use of therapeutic hypothermia. The clinical results of this protocol adapted from randomized studies are similar to the literature.

Diretrizes para manutenção de múltiplos órgãos no potencial doador adulto falecido: Parte III. Recomendações órgãos específicas / Guidelines for potential multiple organ donors (adult). Part III: organ-specific recommendations

A morte encefálica induz várias alterações fisiopatológicas que podem causar lesões em rins, pulmões, coração e fígado. Portanto, a atuação do intensivista durante a manutenção do potencial doador falecido exige cuidados específicos com estes órgãos visando sua maior viabilidade para transplantes. O manejo hemodinâmico cuidadoso, os cuidados ventilatórios e de higiene brônquica minimizam a perda de rins e pulmões para o transplante. A avaliação da condição morfológica e funcional do coração auxilia na avaliação do potencial transplantável deste órgão. Por fim, a avaliação da função hepática, assim como o controle metabólico e a realização de sorologias virais são fundamentais para a orientação das equipes transplantadoras na seleção do órgão a ser doado e no cuidado com o receptor.

Ventilação mecânica não invasiva em pacientes com síndrome respiratória aguda grave, suspeitos de infecção por influenza A - H1N1: relato de casos / Non invasive mechanical ventilation in acute lung injury and swine-origin influenza A H1N1 suspicion: case report

Objetivo: Apresentar, através de relato de caso, a aplicação da ventilação mecânica não invasiva (VMNI) em pacientes com Síndrome Respiratória Aguda Grave (SRAG), suspeitos de H1N1, internados no Centro de Terapia Intensiva (CTI) do Hospital Eduardo de Menezes (HEM). Materiais e Métodos: Quatro mulheres com idades entre 16 e 50 anos, com SRAG, foram submetidas à VMNI em ventiladores micro processados utilizando a máscara full face, com parâmetros mínimos a fim de melhorar a taquidispnéia e a queda da saturação de oxigênio, conforme protocolo criado pela equipe do CTI do HEM. Resultado: após aplicação da VMNI houve melhora do padrão respiratório e da saturação, observados clinicamente e através de gasometria e RX, menor permanência no CTI (3-5 dias), e não houve necessidade de intubação orotraqueal, diminuindo complicações e custos da mesma. Conclusão: Embora a VMNI tenha sido evidenciada como uma pratica controversa para os pacientes sob investigação de H1N1, neste relato de caso mostrou-se eficaz quando aplicado criteriosamente e bem indicado.(AU)

Objectives: To present, in a series of case reports, the use of non invasive ventilation (NIV) in patients with acute lung injury (ALI) and swine-origin influenza A H1N1 suspicion, in Intensive Care Unit of Eduardo de Menezes Hospital (HEM). Materials and Methods: Four women, aged between 16 and 50, with ALI, underwent a protocol of NIV in micro processed ventilators, using full face mask and minimal parameters to obtain an improvement of tachidispnoea and drop of oxygen saturation; according to protocol created by UCI team. Results: There was an improvement of respiratory pattern and saturation, seen clinically and through arterial blood gas analyses and chest radiography; shorter stay in UCI (3-5 days), and there was no need of endotracheal intubation, decreasing complications and costs. Conclusion: Although NIV has been a controversial practice to patients under suspicion of swine-origin influenza, this case report showed efficacy when carefully applied and indicated.(AU)

Management of septic shock.

Severe sepsis is a common disease process affecting some 2-11% of hospital admissions in the US. Severe sepsis and septic shock are associated with considerable morbidity and mortality, and account for a large part of intensive care unit costs. Until recently, the management of septic shock relied on the treatment of underlying infection with antimicrobial agents and surgical removal of any infectious source, and individual support of failing organs. However, in the last few years we have seen huge strides being made in our understanding of the pathophysiology of the sepsis response, and in our ability to manipulate that response. In the last couple of years these advances have come to fruition with the development of a drug, drotrecogin alfa, which specifically reduces mortality from this all too often fatal disease. While intensive early resuscitation remains the cornerstone of management, new approaches are beginning to form part of sepsis management protocols and will lead to improved outcomes for patients with this disease process.

Estudo de pacientes reanimados pós-parada cardiorrespiratória intra e extra-hospitalar submetidos à hipotermia terapêutica / Study of resuscitated in- and out-hospital cardiorespiratory arrest patients undergoing therapeutic hypothermia

OBJETIVO: Conhecer as características dos pacientes submetidos a um protocolo operacional padrão institucional de atendimento a pacientes reanimados após episódio de parada cardiorrespiratória incluindo a aplicação de hipotermia terapêutica. MÉTODOS: Foram analisados retrospectivamente 26 pacientes consecutivos após episódio de parada cardiorrespiratória de janeiro de 2007 a novembro de 2008. RESULTADOS: Todos os casos foram submetidos a hipotermia terapêutica. Idade média de 63 anos, predominantemente do sexo masculino. O local da parada cardiorrespiratória foi extra-hospitalar em 8 casos, pronto socorro em 3, durante internação fora da unidade de terapia intensiva em 13 casos e o bloco cirúrgico em 2 casos. O ritmo de parada foi fibrilação ventricular em sete pacientes, assistolia em 11, atividade elétrica sem pulso em 5 casos e não foi determinado em 3 pacientes. O intervalo entre a parada e o retorno à circulação espontânea foi de 12 ± 5 minutos. O tempo requerido para alcançar a temperatura alvo foi de 5 ± 4 horas, o tempo de hipotermia foi de 22 ± 6 horas e para o reaquecimento usaram-se 9 ± 5,9 horas. Catorze pacientes evoluíram a óbito na unidade de terapia intensiva, representando uma mortalidade de 54 por cento, e três pacientes tiveram o mesmo desfecho durante a internação, determinando uma mortalidade intra-hospitalar de 66 por cento. Houve redução estatisticamente significativa dos valores de hemoglobina (p <0,001), leucócitos (p=0,001), plaquetas (p<0,001), lactato (p<0,001) e potássio (p=0,009), e aumento de proteína C reativa (p=0,001) e RNI (p=0,004) após aplicação de hipotermia. CONCLUSÕES: A elaboração de protocolo operacional padrão de hipotermia terapêutica para o tratamento de pacientes com parada cardiorrespiratória, utilizando-se das rotinas adaptadas de estudos randomizados, resultou em elevada aderência e seus resultados assemelham-se aos dados publicados na literatura.
