Risk factors and trends in injury mortality in Rufiji Demographic Surveillance System, rural Tanzania from 2002 to 2007Ae-Ngibise, Kenneth Ayuurebobi 28 September 2010 (has links)
Research report in partial fulfillment for the degree of MSc (Med), Population Based Field Epidemiology, University of the Witwatersrand / Background
Worldwide, injuries are ranked among the leading causes of death and disability, killing over
5 million people and injuring over 50 million others globally. Approximately 90% of these
deaths occur in developing countries. The burden and pattern of injuries in low-income
countries are poorly known and not well studied. Few studies have been conducted on injury
mortality and therefore this study can add to the scientific literature. Analyzing injury
mortality in rural Tanzania can assist African countries to develop intervention programmes
and policy reform to reduce the burden caused by injuries.
Objectives
The objective of this study was to identify the risk factors and trend in injury mortality in the
Rufiji Demographic Surveillance Area in rural Tanzania from 2002-2007. Specifically, the
study would identify and describe the types and trends in injury mortality, calculate the crude
death rates of injury mortality by gender, SES and age groups, describe the risks factors
associated with injury mortality, and measure association between the risk factors and injury
mortality.
Methods
Rufiji HDSS data used included people aged 1 year and older from 2002-2007. Verbal
Autopsy data was used to determine the causes of death which was based on the tenth
revision of the International Classification of Diseases (ICD 10) recommended by WHO.
Injury Crude death rates (ICDR) were calculated by dividing number of deaths in each year
by person years observed and multiplying by 100,000. Principal Component Analysis (PCA)
was used to construct household wealth index using household characteristics and assets
ownership. Also trend test analysis was done to assess a linear relationship in the injury
mortality rates across the six year period. Poisson regression was used to investigate
v
association between risk factors and injury mortality and all tests for significant associations
were based on p-values at 5% significance level and a 95% confidence interval.
Results
The overall injury crude mortality rate was 33.4 per 100,000 PYO. Injuries contributed 4% of
total mortality burden with statistical significant association between gender, age and
occupation. Mortality rate was higher for males [Adjusted IRR=3.04, P=0.001, 95% CI (2.22
- 4.17)]. The elderly (65+) were 2.8 times more likely to die from injuries compared to
children [Adjusted IRR=2.83, P=0.048, 95% CI (1.01 - 7.93)]. The unemployed, casual
workers, the retired, and farmers all had an increased risk of dying from injuries compared to
students (P<0.005). Most injury deaths were due to road traffic accidents (28%), unspecified
external injuries (20%), drowning (16%), burns (9%), accidental poisoning (8%), homicidal
(8%) and animal attack (5%).
Conclusion
The contribution of injury to mortality burden in the Rufiji Demographic Surveillance Area
was relatively low. However, there is the need to institute measures that would help prevent
injuries. Life saving interventions such as road safety education, regular road maintenance,
rapid response to accidents, use of life jackets for fishermen and recreational swimmers are
very necessary in preventing injuries. Also, proper fishing practices should be imparted to the
populace as precautionary measures to reduce the burden of injury mortality.

Visceral leishmaniasis. Kala-azar. Acute kidney injury. Mortality. Risk factors. RIFLE / ManifestaÃÃes clÃnicas e fatores de risco relacionados à lesÃo renal aguda na Leishmaniose visceral e aplicaÃÃo do critÃrio RifleMichelle Jacintha Cavalcante Oliveira 10 May 2010 (has links)
Background. There are few studies of renal function evaluation in visceral leishmaniasis (Kala-azar). The aim of this study was to investigate the clinical manifest and the risk factors associated with acute kidney injury (AKI) based on RIFLE criteria in patients with visceral leishmaniasis (VL). Methods. A retrospective study of medical records from patients over 14 years old, without previous kidney disease, with VL, treated at SÃo Josà Infectious Diseases Hospital, from 2002 to 2008. Clinical manifestations and risk factors for AKI (defined by using RIFLE criteria) were studied. A multivariate analysis was performed to analyze the risk factors for AKI. Results. A total of 224 patients were included. The mean age was 36Â15 years and 76.8% were males. AKI was observed in 76 patients (33.9% of cases) and % 52.6 (40) were class F on RIFLE criteria. The main clinical symptoms were dyspnea, edema and jaundice in patients with VL and AKI (p<0.05). Oliguria was observed in 6.5% of patients with AKI. Risk factors associated with AKI were male gender (OR=2.2, 95% CI= 1.0-4.7, p=0.03), age > 40 years (OR = 1.05, 95% CI= 1.02-1.08, p < 0.001) and jaundice (OR=2.9, 95% CI= 1.5-5.8 p=0.002). There was an strong association between amphotericin B use and AKI (OR=18.4, 95% CI=7.9-42.8, p<0.0001), whereas glucantime use was associated with a lower incidence of AKI when compared to amphotericin B users (OR=0.05, 95% CI=0.02-0.12, p<0.0001). Mortality was 13.3% and it was higher in AKI patients (30.2% vs. 4.7%, p<0.0001). RIFLE criteria presented mortality 40%, 20.8% e 35% in R, I and F respective class. Conclusions. The risk factors associated with AKI in patients with VL were male gender, advanced age, jaundice and amphotericin B. The last one was the most important factor of AKI in VL. / IntroduÃÃo. Hà poucos dados na literatura que relacionam a Leishmaniose visceral (LV) à lesÃo renal aguda (LRA). O objetivo deste estudo à avaliar as manifestaÃÃes clÃnicas e fatores de risco associados à LRA em pacientes com LV e aplicar o critÃrio RIFLE. MÃtodo. Estudo retrospectivo, incluindo pacientes acima de 14 anos, sem doenÃa renal prÃvia, com diagnÃstico de LV, internados no HSJ entre 2002 e 2008. Foram avaliadas manifestaÃÃes clÃnicas e os fatores de risco relacionados à LRA (avaliada atravÃs do critÃrio RIFLE) nesses pacientes, aplicando regressÃo logÃstica multivariada. Resultados. Foram incluÃdos 224 pacientes com idade mÃdia de 36Â15 anos sendo 76,8% do gÃnero masculino. LRA foi observada em 76 pacientes (33,9%) sendo que 52,6% (40) estavam na classe F do critÃrio RIFLE. Dispneia, edema e icterÃcia foram os principais sinais e sintomas associados à LRA (p<0,05). OligÃria foi observada em 6,5% dos pacientes com LRA. Os fatores de risco associados à LRA foram gÃnero masculino (OR=2,2, 95% IC=1,0-4,7, p=0,03), idade acima de 40 anos (OR = 1,05, 95% IC = 1,02-1,08, p<0,001) e icterÃcia (OR=2,9, 95% IC=1,5-5,8, p=0,002). Foi verificada considerÃvel associaÃÃo entre o emprego de anfotericina B e LRA (OR=18,4, 95% IC=7,9-42,8, p<0,0001), contudo o uso de glucantime foi associado a menor ocorrÃncia de LRA (OR=0,05, 95% IC=0,02-0,12, p<0,0001). A mortalidade geral foi 13,3% e foi mais alta nos pacientes que desenvolveram LRA (30,2% vs. 4,7%, p<0,0001). Os percentuais de mortalidade nas classes R, I e F foram respectivamente 40%, 20,8% e 35%. ConclusÃes. Os fatores de risco preditores de LRA em pacientes com LV foram sexo masculino, anfotericina B, idade acima de 40 anos e icterÃcia. Anfotericina B foi o fator mais importante de LRA na LV.

Predictors of Post-injury Mortality in Elderly Patients with Trauma: A Master's ThesisPsoinos, Charles M. 21 July 2016 (has links)
Background: Traumatic injury remains a major cause of mortality in the US. Older Americans experience lower rates of injury and higher rates of death at lower injury severity than their younger counterparts. The objectives of this study were to explore pre-injury factors and injury patterns that are associated with post-discharge mortality among injured elderly surviving index hospitalization.
Methods: We queried a 5% random sample of Medicare beneficiaries (n=2,002,420) for any hospitalization with a primary ICD-9 diagnosis code for injury. Patients admitted without urgent/emergent admission were excluded, as well as patients presenting from inpatient hospitalization or rehabilitation. The primary endpoint was all-cause mortality. Patients were categorized into three mortality groups: death within 0-30 days, 31-90 days, or 91- 365 days post-discharge from the index hospitalization. These groups were compared with those who survived greater than one year post-discharge. Univariate tests of association and multivariable logistic regression models were utilized to identify factors associated with mortality during the 3 examined periods.
Results: 83,439 elderly patients (4.2%) were admitted with new injuries. 63,628 met inclusion criteria. 1,936 patients (3.0%) died during their index hospitalization, 2,410 (3.8%) died within 0-30 days, 3,084 (4.8%) died within 31-90 days, and 5,718 (9.0%) died within 91- 365 days after discharge. In multivariable adjusted models, advanced age, male sex, and higher Elixhauser score were associated with post-discharge mortality. The presence of critical injury had the greatest effect on mortality early after injury (0-30 days, OR 1.81, CI 1.64-2.00). Discharge to anywhere other than home without services was associated with an increased odds of dying.
Conclusions: Socio-demographic characteristics, disposition, and co-morbid factors were the strongest predictors of post-discharge mortality. Efforts to reduce injury-related mortality should focus on injury prevention and modification of co-morbidities.

Estudo de pulmões de ratos reperfundidos em um modelo experimental ex-vivo: comparação entre duas soluções de preservação (Perfadex® e Celsior®) / Study of reperfused rat lungs in an ex vivo experimental model: comparison of two preservation solutions (Perfadex® and Celsior®)Menezes, Arteiro Queiroz 21 May 2013 (has links)
INTRODUÇÃO: A lesão de isquemia-reperfusão continua sendo considerada a maior causa de mortalidade relacionada ao transplante de pulmão e sua gravidade é influenciada por diversos fatores, dentre eles, a preservação pulmonar. OBJETIVO: Comparar duas soluções de preservação pulmonar, Perfadex® e Celsior®, quanto a capacidade de preservação de tecido pulmonar isquêmico. MÉTODOS: Sessenta pulmões de ratos preservados com Perfadex®, Celsior® ou solução salina após períodos de isquemia hipotérmica de 6 ou 12 horas, foram reperfundidos com sangue homólogo em modelo experimental ex-vivo durante 60 minutos consecutivos. A cada 10 minutos os dados de gasometria, hematócrito, mecânica ventilatória, hemodinâmica e peso do bloco cardiopulmonar foram registrados. Ao final da reperfusão o pulmão esquerdo foi pesado e acondicionado por 48h a 70oC para obtenção da razão peso úmido/peso seco, bem como amostras de tecido pulmonar foram retiradas para histopatologia, microscopia eletrônica e TUNEL. A análise estatística incluiu a comparação entre as soluções e os tempos de isquemia, utilizando ANOVA e Kruskall-Wallis. O nível de significância foi de 5%. RESULTADOS: A comparação entre as complacências de pulmões preservados com Celsior® e Perfadex® nos tempos de isquemia de 6 e 12 horas não apresentou significância estatística (p=0,161 e p=0,316, respectivamente). Os pulmões submetidos a 6 horas de isquemia apresentaram complacência pulmonar superior aos de 12 horas (Perfadex® p=0,02; Celsior® p=0,019; Salina p=0,016). Os valores de pressão arterial pulmonar foram semelhantes entre as três soluções nos dois tempos de isquemia, bem como na comparação entre os tempos de 6 e 12 horas, independente da solução. A Capacidade Relativa de Oxigenação não demonstrou diferença estatística entre as três soluções, independentemente do tempo de isquemia. Na comparação entre os dois tempos de isquemia, o desempenho da oxigenação foi significativamente pior nos pulmões preservados com salina por 12 horas (p=0,001). A razão peso úmido/peso seco não apresentou diferença estatística significante entre as três soluções nos dois tempos de isquemia, porém na comparação entre os tempos de isquemia, os pulmões preservados com Perfadex® apresentaram uma relação peso úmido/peso seco maior no tempo de isquemia mais longo (p=0,001). À microscopia óptica, pulmões preservados com salina apresentaram mais edema que os demais, independentemente do tempo de isquemia. A avaliação da apoptose celular através do método de TUNEL não mostrou diferença estatisticamente significativa na comparação entre os grupos. CONCLUSÃO: Os pulmões preservados com Perfadex® e Celsior® apresentaram desempenho similar em relação às trocas gasosas e parâmetros hemodinâmicos e de mecânica ventilatória. Os pulmões preservados com Perfadex® por 12 horas apresentaram mais edema. Os achados histopatológicos não diferiram entre os grupos estudados / INTRODUCTION: Ischemia-reperfusion injury remaisn the leading cause of mortality related to lung transplantation. Its severity is influenced by several factors including lung preservation. OBJECTIVE: To compare two lung preservation solutions, Perfadex® and Celsior® and its ability to preserve ischemic lung tissue. METHODS: Sixty rat lungs were preserved with Perfadex®, Celsior® or saline after a cold ischemic period of 6 or 12 hours and were then reperfused with homologous blood in an ex vivo experimental model for 60 consecutive minutes. At 10-minute intervals during reperfusion of the heart-lung blocks, data were collected for blood gases, hematocrit, mechanical ventilation, hemodynamic and the heart-lung block weight was recorded. At the end of reperfusion, the left lung was weighed and packaged kept at 70oC for 48h to obtain the wet-to-dry weight ratio. Lung tissue samples were processed for histology, electron microscopy and TUNEL. Statistical analysis included a comparison of the solutions and ischemic times, using ANOVA and Kruskal-Wallis. The significance level was set at 5%. RESULTS: The comparison between the compliance of lungs preserved with Celsior® and Perfadex® in ischemic times of 6 and 12 hours was not statistically significant (p=0.161 and p=0.316, respectively). The lungs subjected to 6 hours of ischemia showed higher lung compliance compared to 12 hours (p=0.02 Perfadex®; Celsior® p=0.019; saline p=0.016). The pulmonary artery pressure values were similar between the three solutions in two stages of ischemia and comparing the times of 6 and 12 hours, regardless of the solution. The Relative Oxygenation Capacity showed no significant difference between the three solutions tested, regardless of the ischemic time. The comparison between the two ischemic times showed that oxygenation capacity was significantly worse in lungs preserved with saline for 12 hours (p=0.001). The wet-to-dry weight ratio showed no statistically significant difference between the three solutions in both ischemic times. However, when ischemic times were compared, Perfadex® showed greater wet-to-dry weight ratio in lungs submitted to 12 hours of ischemia (p=0.001). Light microscopy showed that lungs preserved with saline had more edema than the others, regardless of the ischemic time. Assessment of apoptosis by the TUNEL assay showed no statistically significant difference in the comparison between the groups. CONCLUSIONS: The lungs preserved with Celsior® and Perfadex® performed evenly in regards to gas exchange, hemodynamics and ventilatory mechanics. The lungs preserved with Perfadex® for 12 hours were more edematous. Histopathology findings did not differ between the groups

Avaliação de fatores de risco para injúria renal aguda (IRA) em pacientes oncológicos na UTI / Evaluation of risk factors for acute kidney injury (AKI) in cancer patients in the ICUDal Santo, Ana Cristina Martins 04 April 2014 (has links)
Introdução: Pacientes portadores de câncer estão sobrevivendo mais devido aos avanços no diagnóstico precoce e tratamento dos tumores. A diminuição da mortalidade relacionada ao câncer e o envelhecimento da população acarretaram um número crescente de pacientes oncológicos internados em UTI. Objetivos: Identificar a prevalência e os fatores de risco para IRA nos pacientes oncológicos críticos. Métodos: Foram avaliados, prospectivamente, 371 pacientes oncológicos internados nas UTIs do Instituto do Câncer do Estado de São Paulo e do Hospital AC Camargo, entre novembro de 2011 a março de 2013. Os pacientes foram avaliados na admissão, 24h e 48h da internação na UTI. Foram coletados os parâmetros demográficos, clínicos e laboratoriais os quais foram analisados para os desfechos IRA, conforme o critério AKIN (Cr > 0,3 mg/dl ou aumento de 50% sobre a Cr basal em 48h) e óbito na UTI. Os dados foram submetidos à análise bivariada e multivariada. Resultados: A incidência de IRA nos pacientes oncológicos foi de 45,1%, sendo que apenas 5,2% necessitaram de tratamento dialítico. Os pacientes com IRA apresentaram mais frequentemente admissão cirúrgica (49% IRA vs 34% sem IRA; p=0,022). Na admissão à UTI, os fatores associados ao desenvolvimento de IRA (IRA vs sem IRA) foram: ventilação mecânica (26,6% vs 16,0%; p=0,031), frequência cardíaca (88 bpm vs 82 bpm; p=0,029), balanço hídrico (575 ml vs 275 ml; p = 0,0002), lactato (19 mg/dL vs 17 mg/dL; p= 0,046) e fósforo (3,9 mg/dL vs 3,4 mg/dL; p < 0,0001). A taxa de óbito hospitalar foi de 37,3% sendo que 25,3% ocorreu na UTI. A mortalidade foi mais prevalente em pacientes com câncer hematológico (8,6% sobreviventes vs 19,5% óbitos; p = 0,008), procedentes do pronto atendimento (23,5% sobreviventes vs 34,1% óbitos; p = 0,002), admissão clínica (50,4% sobreviventes vs 84,1% óbitos; p < 0,0001) e internação não planejada (59,9% vs 86,6% óbitos; p < 0,0001). Outros fatores relacionados ao óbito foram: sinais de congestão, uso de drogas vasoativas, choque séptico e infecção respiratória (p < 0,0001). Os dias de internação prévios à admissão na UTI também se relacionaram ao óbito (6 dias óbitos vs 2 dias sobreviventes; p < 0,0001). Os exames laboratoriais que se relacionaram ao óbito foram (sobreviventes vs óbitos): hipoalbuminemia (2,7 g/dL vs 2,4 g/dL; p= 0,003), aumento do INR (1,3 vs 1,5; p < 0,0001); aumento do lactato (17 mg/dL vs 20,5 mg/dL; p = 0,037), PCR (41,8 mg/dL vs 148,4 mg/dL; p < 0,0001) e TP (69% vs 59,5%; p = 0,001). Conclusão: A IRA é frequente em pacientes oncológicos admitidos na UTI e apresenta alta mortalidade. As ocorrências de IRA e óbito encontram-se mais relacionados com a gravidade das disfunções orgânicas no momento da admissão à UTI, do que às características da neoplasia de base / Introduction: Cancer patients are currently presenting longer survival due to advances in diagnosis and treatment. Mortality reduction related to cancer and aging of population had led to an increased admission of cancer patients in the ICU. Objectives: Evaluation of the prevalence and risk factors for AKI in critically ill cancer patients. Methods: It was prospectively evaluated 371 cancer patients admitted to the ICU in Instituto do Câncer do Estado de São Paulo and Hospital AC Camargo, from November 2011 until March 2013. Patients were evaluated at admission, 24h and 48h in the ICU. Demographic, clinical and laboratory parameters were collected which were correlated with the outcome AKI (AKIN I - Cr > 0.3 mg/dL or 50% increase over baseline in 48h) and mortality in the ICU. Statistical analysis was performed using bivariate and multivariate analysis. Results: The incidence of AKI in cancer patients was 45.1% but only 5.2% were dialysed. AKI patients were more frequently admitted due to surgical admission (AKI 53% vs. 49% non-AKI, p=0.022). At ICU admission, factors associated with AKI development (AKI vs. non-AKI) were: mechanical ventilation (26.6% vs. 16%, p =0.031), heart beats (88 bpm vs. 82 bpm, p=0.029), fluid balance (575 ml vs. 275 ml, p=0.0002), lactate (19 mg/dLvs. 17 mg/dL, p=0.046) and phosphorus (3.9 mg/dL vs. 3.4 mg/dL, p < 0.0001). Hospital mortality rate was 37.3% whereas ICU mortality was 25.3%. Mortality was more prevalent in patients with hematological cancer (8.6% survivors vs. 19.5% non-survivors, p = 0.008), patients from emergency room (23.5% survivors vs. 34.1% non-survivors, p = 0.002), patients with clinical admission (50.4% survivors vs. 84.1% non-survivors, p < 0.0001) and non-elective admission (59.9% vs. 86.6% non-survivors, p < 0.0001). Other factors related to mortality were: volume overload, vasoactive drugs use, septic shock and pulmonary infection (p < 0.0001). Hospitalization period before ICU admission also correlated with mortality (6 days survivors vs. 2 days non-survivors, p 0.0001). The laboratory parameters that correlated to mortality were (survivors vs. non-survivors): hypoalbuminemia (2.7 g/dL vs. 2.4 g/dL, p=0.003), increased INR (1.3 vs. 1.5, p < 0.0001), increased lactate (17 mg/dL vs. 20.5 mg/dL, p=0.037), PCR (41.8 mg/dL vs 148.4 mg/dL, p < 0.0001) e PT (69% vs. 59.5%, p = 0.001). Conclusions: AKI is a frequent complication in cancer patients admitted to ICU, presenting high mortality rate. AKI and mortality outcomes are more related to the severity of organs dysfunction at ICU admission than the patient´s cancer disease

A mortalidade foi mais prevalente em pacientes com câncer hematológico (8,6% sobreviventes vs 19,5% óbitos; p = 0,008), procedentes do pronto atendimento (23,5% sobreviventes vs 34,1% óbitos; p = 0,002), admissão clínica (50,4% sobreviventes vs 84,1% óbitos; p < 0,0001) e internação não planejada (59,9% vs 86,6% óbitos; p < 0,0001). Outros fatores relacionados ao óbito foram: sinais de congestão, uso de drogas vasoativas, choque séptico e infecção respiratória (p < 0,0001). Os dias de internação prévios à admissão na UTI também se relacionaram ao óbito (6 dias óbitos vs 2 dias sobreviventes; p < 0,0001). Os exames laboratoriais que se relacionaram ao óbito foram (sobreviventes vs óbitos): hipoalbuminemia (2,7 g/dL vs 2,4 g/dL; p= 0,003), aumento do INR (1,3 vs 1,5; p < 0,0001); aumento do lactato (17 mg/dL vs 20,5 mg/dL; p = 0,037), PCR (41,8 mg/dL vs 148,4 mg/dL; p < 0,0001) e TP (69% vs 59,5%; p = 0,001). Conclusão: A IRA é frequente em pacientes oncológicos admitidos na UTI e apresenta alta mortalidade. As ocorrências de IRA e óbito encontram-se mais relacionados com a gravidade das disfunções orgânicas no momento da admissão à UTI, do que às características da neoplasia de base / Introduction: Cancer patients are currently presenting longer survival due to advances in diagnosis and treatment. Mortality reduction related to cancer and aging of population had led to an increased admission of cancer patients in the ICU. Objectives: Evaluation of the prevalence and risk factors for AKI in critically ill cancer patients. Methods: It was prospectively evaluated 371 cancer patients admitted to the ICU in Instituto do Câncer do Estado de São Paulo and Hospital AC Camargo, from November 2011 until March 2013. Patients were evaluated at admission, 24h and 48h in the ICU. Demographic, clinical and laboratory parameters were collected which were correlated with the outcome AKI (AKIN I - Cr > 0.3 mg/dL or 50% increase over baseline in 48h) and mortality in the ICU. Statistical analysis was performed using bivariate and multivariate analysis. Results: The incidence of AKI in cancer patients was 45.1% but only 5.2% were dialysed. AKI patients were more frequently admitted due to surgical admission (AKI 53% vs. 49% non-AKI, p=0.022). At ICU admission, factors associated with AKI development (AKI vs. non-AKI) were: mechanical ventilation (26.6% vs. 16%, p =0.031), heart beats (88 bpm vs. 82 bpm, p=0.029), fluid balance (575 ml vs. 275 ml, p=0.0002), lactate (19 mg/dLvs. 17 mg/dL, p=0.046) and phosphorus (3.9 mg/dL vs. 3.4 mg/dL, p < 0.0001). Hospital mortality rate was 37.3% whereas ICU mortality was 25.3%. Mortality was more prevalent in patients with hematological cancer (8.6% survivors vs. 19.5% non-survivors, p = 0.008), patients from emergency room (23.5% survivors vs. 34.1% non-survivors, p = 0.002), patients with clinical admission (50.4% survivors vs. 84.1% non-survivors, p < 0.0001) and non-elective admission (59.9% vs. 86.6% non-survivors, p < 0.0001). Other factors related to mortality were: volume overload, vasoactive drugs use, septic shock and pulmonary infection (p < 0.0001). Hospitalization period before ICU admission also correlated with mortality (6 days survivors vs. 2 days non-survivors, p 0.0001). The laboratory parameters that correlated to mortality were (survivors vs. non-survivors): hypoalbuminemia (2.7 g/dL vs. 2.4 g/dL, p=0.003), increased INR (1.3 vs. 1.5, p < 0.0001), increased lactate (17 mg/dL vs. 20.5 mg/dL, p=0.037), PCR (41.8 mg/dL vs 148.4 mg/dL, p < 0.0001) e PT (69% vs. 59.5%, p = 0.001). Conclusions: AKI is a frequent complication in cancer patients admitted to ICU, presenting high mortality rate. AKI and mortality outcomes are more related to the severity of organs dysfunction at ICU admission than the patient´s cancer disease
