AIM: To assess the prognostic value of APACHE II and SAPS II scales to predict brain death evolution of neurocritical care patients. PATIENTS AND METHODS: Retrospective observational study performed in a tertiary hospital. Include 508 patients over 16 years old, hospitalized in ICU for at least 24 hours. The variables of interest were: demographic data, risk factors, APACHE II, SAPS II and outcome. RESULTS: Median age: 41 years old (IR: 25-57). Males: 76.2%. Most frequent reason for admission: trauma (55.3%). Medians: Glasgow Coma Scale (GCS), 10 points; APACHE II, 13 points; SAPS II, 31 points; and ICU stay, 5 days. Mortality in the ICU was 28.5% (n = 145) of whom 44 (8.7%) evolved to brain death. Univariate logistic regression analysis showed that GCS, APACHE II and SAPS II scores, as well as ICU stay days behaved as predictors of brain death evolution. However, the multivariate analysis performed including APACHE II and SAPS II scores showed that only APACHE II maintained statistical significance, despite the good discrimination of both scores. CONCLUSION: Transplant coordinators might use the APACHE II score as a tool to detect patients at risk of progression to brain death, minimizing the loss of potential donors.
TITLE: APACHE II y SAPS II como predictores de evolucion a muerte encefalica en pacientes neurocriticos.Objetivo. Evaluar si las escalas pronosticas APACHE II (Acute Physiology and Chronic Health Evaluation II) y SAPS II (Simplified Acute Physiology Score II) son capaces de predecir la evolucion a muerte encefalica en pacientes neurocriticos. Pacientes y metodos. Estudio retrospectivo, observacional, realizado en un hospital de tercer nivel. Se incluyo a 508 pacientes mayores de 16 años, ingresados con patologia neurocritica aguda, con estancia en la unidad de cuidados intensivos de al menos 24 horas. Las variables de interes fueron: datos demograficos, factores de riesgo, APACHE II, SAPS II y resultado pronostico. Resultados. Mediana de edad: 41 años (rango intercuartilico: 25-57). Varones: 76,2%. Motivo de ingreso mas frecuente: traumatismo (55,3%). Medianas: escala de coma de Glasgow (GCS), 10 puntos; APACHE II, 13 puntos; SAPS II, 31 puntos; y estancia en cuidados intensivos, cinco dias. La mortalidad en la unidad de cuidados intensivos fue de 145 (28,5%). De ellos, 44 (8,7%) evolucionaron a muerte encefalica. El analisis de regresion logistica univariante mostro que la GCS, las escalas APACHE II y SAPS II, y los dias de estancia en la unidad de cuidados intensivos se comportaron como variables predictoras de evolucion a muerte encefalica. Sin embargo, en el analisis multivariante realizado con APACHE II y SAPS II, se evidencio que solo APACHE II mantiene significacion estadistica, a pesar de la buena discriminacion de ambas escalas. Conclusion. Los coordinadores de trasplantes podrian usar la escala APACHE II como una herramienta para detectar pacientes con riesgo de evolucion a muerte encefalica, minimizando la perdida de potenciales donantes.

Recent research in kidney transplantation has revealed differences in the evolution of renal function among patients transplanted from 2 alternative programs for donation after circulatory death (DCD). A retrospective, observational, single-center study was carried out from 2013 to 2016 at a level III hospital intensive care unit (ICU) to assess the progression of kidney recipients after transplants from uncontrolled DCD (uDCD) or controlled DCD (cDCD). The following variables were collected for data analysis: demographics, comorbidities, type of donation, lactate, hemoglobin and glucose levels at ICU admission, creatinine concentration at ICU admission, at-hospital ward transfer, at-hospital discharge, radioisotope imaging results, ICU and in-hospital length of stay, and mortality. There were 87 patients eligible for analysis, 42.5% of which were uDCD recipients. Improvement in kidney function was significantly delayed after uDCD compared with cDCD. A multivariate analysis showed that both uDCD and lactate levels at ICU admission increase the risk of poor outcome after renal transplantation. No deaths were registered in either patient group. Our results suggest that kidney transplantation recipients from uDCD recover renal function at a slower rate than patients transplanted from cDCD, a factor that does not affect mortality.

OBJECTIVE: To investigate the characteristics and evolution of controlled donation after circulatory death (DCD) type III. MATERIALS AND METHODS: Observational and retrospective study of controlled DCD type III of donors conducted from 2014 to 2016. Clinical data, intensive care unit (ICU) stay, cause of death, warm ischemia time, and total time were collected. Delayed graft function (DGF) and survival of renal transplant were also registered. Qualitative variables are described as frequencies and absolute values and quantitative variables as medians and interquartile ranges. RESULTS: A total of 21 donors were collected; 71% (15) were males, median age was 55 years (interquartile range [IR] 48-72), and median ICU stay was 7 days (IR 4-12). The main cause of death was anoxic encephalopathy (57%, 12), followed by intracerebral hemorrhage (28%, 6). In 48%, withdrawal of life support occurred in the operating room, and 98% of donors were preserved by abdominal super-rapid cannulation technique. Average warm ischemia time was 20 minutes (IR 16-24), and total ischemia time was 26 minutes (IR 23-34). Of the donations, 57% were livers and 90% were kidneys. Out of 42 kidneys donated, 54% (23) of them were valid. Median renal transplant hospital stay was 18 days (IR 6-24), and 46% develop DGF. Survival at discharge was 100%. CONCLUSION: DCD type III ensures a source of organs. The main cause of death was anoxic encephalopathy. Most donors were able to donate some solid organ.

In recent years, the broadening of indications for renal transplantation, together with the progressive reduction of donations following brain stem death, has led to living donation being considered in increasing numbers of cases for renal transplantation. To investigate this further, it is necessary to assess the impact it has on the postoperative outcomes in the intensive care unit (ICU). Our group conducted a retrospective, observational, single-center study from 2013 to 2016 to evaluate differences in outcomes between living and cadaveric kidney donation both during ICU admission and total hospitalization. We compared differences in characteristics between living and deceased graft recipients including demographics, comorbidities, analytical data, radioisotope imaging test results, complications, ICU and hospital ward length of stay, and mortality. In all, 387 patients were eligible for analysis, and 13% received living donor grafts. Our results demonstrate that this group had significantly fewer complications, shorter length of hospital stay, and reduced mortality in comparison with recipients of cadaveric donor grafts. The better postoperative outcomes from living donor grafts could result from careful selection of the donor and less inflammatory injury, minimizing risk in the postoperative period.

OBJECTIVE: This study aims to compare a shorter cold ischemia time with the present one in relation to the complications developed in liver transplantations. DESIGN: This is a retrospective, observational study of orthotopic liver transplantations performed with grafts from brain-dead donors during 12 months at a University Hospital (Seville). We compare incidence rates of complications (reperfusion syndrome, arterial and biliary complications, and prostaglandin requirements) between two groups according to cold ischemia times (group A < 6 hours; group B > 6 hours). RESULTS: Sixty cases were included. There were more males in both groups as donors (55.5%) and recipients (75%). The median age was higher in group B in two cases. The Model for End-stage Liver Disease score was higher in patients with a shorter cold ischemia time, with a median of 20 hours (range, 16 to 26.5 hours). We observed that reperfusion syndrome (3.4% vs. 13.3%; P = .353), vascular complications (6.9% vs. 24.1%; P = .144), biliary tract complications (13.8% vs. 20.7%; P = .730), and prostaglandin requirements (3.4% vs. 20.7%; P = .102) were more common in group B, although without reaching statistical significance. After uni- and multivariate analyses, cold ischemia time longer than 6 hours was the only risk factor to develop complications (odds ratio: 3.578; 95% confidence interval: 1.125 to 11.374, P = .031). CONCLUSION: According to the results of our analysis, cold ischemia times longer than 6 hours, as tends to be the usual procedure in most centers, imply higher rates of complications after liver transplantation.

OBJECTIVE: This study aims to determine if donor grafts of patients older than 65 years develop more post-transplantation complications than those of younger patients. DESIGN: This is a retrospective, observational study of liver transplant recipients during 12 months in Virgen del Rocio University Hospital. We compare incidence rates of reperfusion syndrome, acute kidney injury, and need for intra- and postoperative red blood cell transfusions in two donor age groups in which group A is <65 years old and group B is ≥65 years old. RESULTS: Sixty cases were included. Reperfusion syndrome, acute kidney injury, and both intra- and postoperative red blood cell transfusion were more frequent in group A than group B (11.4% vs. 4%, P = .390; 44% vs. 32%, P = .423; 68.8% vs. 48%, P = .120; and 70.6% vs. 64%, P = .779, respectively). Six recipients (17.1%) died at 12 months from group A whereas there were no deaths register in group B during that time (P = .036). CONCLUSION: Our results showed that including elderly donors does not aggravate incidence of complications, emphasizing that advanced age should not be an exclusion criteria for liver transplantation.

OBJECTIVE: The objective of this study is to assess the S100B protein serum concentrations from brain dead (BD) donors to understand whether its level could provide clinical information during BD diagnosis as a potential confirmatory test. METHODS: During 12 months, 26 patients declared BD were prospectively included in this study. Once the diagnosis of BD was achieved, serum S100B protein levels were measured using an electrochemiluminescence assay. For analytical purposes, we selected the maximum S100B serum value reached during the first 5 days of evolution from a historical cohort of 124 survived patients after a severe brain injury (SBI), as well as from 18 healthy donors (HD) and a subgroup of patients who had severe traumatic brain injuries (TBIs) without extracranial injuries. RESULTS: Mean age was 53.48 years (SD, 18.91 years). The BD group had significantly higher S100B serum levels (1.44 µg/L; interquartile ratio [IR], 0.63-3.68) than the SBI (0.34 µg/L; IR, 0.21-0.60) and HD groups (0.06 µg/L; IR, 0.03-0.07; P < .001). Analysis of S100B levels depending on the main cause responsible for BD development showed significant differences between subgroups (P = .012). S100B serum levels were higher in the isolated TBI BD group (P = .004). The S100B value showed an odds ratio for BD diagnosis of 8.38 (95% confidence interval [CI], 1.16-60.45; P = .035). Reciever operating characteristic analysis revealed an area under the curve of 0.92 (95% CI, 0.79-1.00; P = .007). We set a cut-off value of 2 µg/L in S100B serum concentrations. At this level, the diagnostic properties of S100B would reach 100% of specificity and positive predictive value (PPV), and sensitivity and negative predictive value (NPV) of 60% and 86.7%, respectively. CONCLUSION: This preliminary analysis shows for the very first time that BD is associated with higher S100B serum levels, compared with other neurocritical care patients. We also found that the cause of BD development must be considered. Specifically, S100B serum levels in severe isolated TBI patients-with clinical exploration compatible with BD-could be used in a future as confirmatory test.

BACKGROUND AND PURPOSE: Heart transplantation is a procedure with a high mortality rate. Altered kidney function (AKF) after a heart transplant is common. The purpose of this study was to determine the incidence of and associated factors for renal dysfunction among patients who underwent heart transplantation in our hospital between January 2006 and November 2008. PATIENTS AND METHODS: This retrospective observational study was performed on all patients receiving a heart transplant between January 1, 2006 and November 15, 2008. The following variables were recorded: patient comorbidities, indication, presurgical urea and creatinine levels, donor variables, surgical procedure, and postoperative features. RESULTS: A total of 54 heart transplantations were performed with 68.5% of patients being male. The average age at transplant was 49.52 years (±13.45 y) and the mean weight 72.5 kg (±14.8 kg). Overall mortality was 28.30%. Of the 54 patients, 70.4% showed AKF during the first week after transplantation; 30.61% were in stage III according to the Acute Kidney Injury classification. There were no statistically significant differences between the group of patients with versus without renal failure, except for the extracorporeal surgery time, which was significantly longer among those patients who had AKF, and glycemia, which was also higher in the immediate postoperative period. Analysis of patient mortality showed no significant differences for the patients with AKF (80% vs 68.4%; P=31). CONCLUSIONS: The rate of acute kidney failure was high (70.4%), as was the use of chronic renal replacement therapy (28.85%), but it decreased considerably when followed over time.
