- Impact of intensive glycemic control on acute renal injury: a randomized clinical trial(2019) SANTANA-SANTOS, Eduesley; KANKE, Patricia Hatanaka; VIEIRA, Rita de Cassia Almeida; OLIVEIRA, Larissa Bertacchini de; FERRETTI-REBUSTINI, Renata Eloah de Lucena; MENEZES, Andreia Freire de; BARRETO, Ikaro Daniel de Carvalho; HAJJAR, Ludhmila AbrahaoObjective: To evaluate the impact of intensive glycemic control on the reduction of the incidence of acute renal injury in adult patients undergoing cardiac surgery. Methods: Randomized clinical trial, evaluating 95 patients undergoing two glycemic control strategies. Patients were randomized to the intervention n group (IG), with the goal of maintaining postoperative glycemia between 90 and 110 mg/dl. For patients allocated into the conventional group (CG) the goal was to maintain glycaemia between 140 and 180 mg/dl. The insulin dose adjustment was based on undiluted arterial blood glucose measurements at one hour intervals, by means of a blood glucose and beta-ketone monitoring system. Results: The incidence of acute kidney injury was 53.7% (KDIGO stages 1, 2 or 3). There was no significant difference between the groups regarding the primary outcome (p=0.294). However, a greater frequency of complete renal function recovery (p = 0.010), ICU discharge (p = 0.028), and hospital discharge (p = 0.048) was found among patients undergoing conventional glycemic control. The use of intensive glycemic control was associated with longer ICU stay (p=0.031). The number of episodes of hypoglycemia was similar in both groups (1.6 +/- 0.9 vs. 1.3 +/- 0.6, p=0.731), demonstrating the safety of the strategies used. Conclusion: The impact of intensive glycemic control on reducing the incidence of acute kidney injury was not observed. In contrast, patients treated in the CG had a higher frequency of complete renal function recovery.
conferenceObject Endovascular Therapeutic Hypothermia Is Feasible as an Adjuvant Therapy in Acute ST-Segment Elevation Myocardial Infarction Patients Without Delay in Door-to-Balloon Time(2019) DALLAN, Luis; GIANNETTI, Natali; DAE, Michael; POLASTRI, Thatiane; ROCHITTE, Carlos Eduardo; NOMURA, Cesar Higa; HAJJAR, Ludhmila Abrahao; BERNOCHE, Claudia; LAGE, Silvia; LIMA, Felipe; NICOLAU, Jose Carlos; TAVARES JR., Mucio; RIBEIRO, Expedito; KALIL JR., Roberto; LEMOS, Pedro A.; TIMERMAN, SergioconferenceObject Effects of Aerobic and Inspiratory Training on Skeletal Muscle Microrna-1 and Downstream-Associated Pathways in Patients With Systolic Heart Failure(2019) ANTUNES-CORREA, Ligia M.; TREVIZAN, Patricia; BACURAU, Aline V.; FERREIRA-SANTOS, Larissa; GOMES, Joao L.; URIAS, Ursula; OLIVEIRA, Patricia; ALVES, Maria-Janieire N.; ALMEIDA, Dirceu R.; BRUM, Patricia C.; OLIVEIRA, Edilamar M.; HAJJAR, Ludhmila; KALIL FILHO, Roberto; NEGRAO, Carlos E.- Dynamic cerebral autoregulation: A marker of post-operative delirium?(2019) CALDAS, Juliana R.; PANERAI, Ronney B.; BOR-SENG-SHU, Edson; FERREIRA, Graziela S. R.; CAMARA, Ligia; PASSOS, R. H.; DE-LIMA-OLIVEIRA, Marcelo; GALAS, Filomena R. B. G.; ALMEIDA, Juliano P.; NOGUEIRA, Ricardo C.; MIAN, Natalia; GAIOTTO, Fabio A.; ROBINSON, Thompson G.; HAJJAR, Ludhmila A.Objective: We investigated the potential association of cerebral autoregulation (CA) with postoperative delirium (PD), a common complication of cardiac surgery with cardiopulmonary bypass (CPB). Methods: In patients undergoing coronary artery bypass graft (CABG) surgery with CPB, cerebral blood flow velocity (CBFV) and blood pressure (BP) were continuously recorded during 5-min preoperatively (T1), after 24 h (T2), and 7 days after procedure (T3). Prospective multivariate logistic regression analysis was performed to determine the independent risk factors of PD. Autoregulation index (ARI) was calculated from the CBFV response to a step change in BP derived by transfer function analysis. Results: In 67 patients, mean age 64.3 +/- 9.5 years, CA was depressed at T2 as shown by values of ARI (3.9 +/- 1.7), compared to T1 (5.6 +/- 1.7) and T3 (5.5 +/- 1.8) (p < 0.001). Impaired CA was found in 37 (55%) patients at T2 and in 7 patients (20%) at T3. Lower ARI at T1 and T2 were predictors of PD (p = 0.003). Conclusion: Dynamic CA was impaired after CABG surgery with CPB and was a significant independent risk factor of PD. Significance: Assessment of CA before and after surgery could have considerable potential for early identification of patients at risk of PD, thus reducing poor outcomes and length of stay.
- Pregnancy in Women with Complex Congenital Heart Disease. A Constant Challenge(2019) AVILA, Walkiria Samuel; RIBEIRO, Veronica Martins; ROSSI, Eduardo Giusti; BINOTTO, Maria Angelica; BORTOLOTTO, Maria Rita; TESTA, Carolina; FRANCISCO, Rossana; HAJJAR, Ludhmilla Abraao; MIURA, NanaBackground: The improvement in surgical techniques has contributed to an increasing number of childbearing women with complex congenital heart disease (CCC). However, adequate counseling about pregnancy in this situation is uncertain, due to a wide variety of residual cardiac lesions. Objectives: To evaluate fetal and maternal outcomes in pregnant women with CCC and to analyze the predictive variables of prognosis. Methods: During 10 years we followed 435 consecutive pregnancies in patients (pts) with congenital heart disease. Among of them, we selected 42 pregnancies in 40 (mean age of 25.5 +/- 4.5 years) pts with CCC, who had been advised against pregnancy. The distribution of underlying cardiac lesions were: D-Transposition of the great arteries, pulmonary atresia, tricuspid atresia, single ventricle, double-outlet ventricle and truncus arteriosus. The surgical procedures performed before gestation were: Fontan, Jatene, Rastelli, Senning, Mustard and other surgical techniques, including Blalock, Taussing, and Glenn. Eight (20,0%) pts did not have previous surgery. Nineteen 19 (47.5%) pts had hypoxemia. The clinical follow-up protocol included oxygen saturation recording, hemoglobin and hematocrit values; medication adjustment to pregnancy, anticoagulation use, when necessary, and hospitalization from 28 weeks, in severe cases. The statistical significance level considered was p < 0.05. Results: Only seventeen (40.5%) pregnancies had maternal and fetal uneventful courses. There were 13 (30.9%) maternal complications, two (4.7%) maternal deaths due to hemorrhage pos-partum and severe pre-eclampsia, both of them in women with hypoxemia. There were 7 (16.6%) stillbirths and 17 (40.5%) premature babies. Congenital heart disease was identified in two (4.1%) infants. Maternal and fetal complications were higher (p < 0.05) in women with hypoxemia. Conclusions: Pregnancy in women with CCC was associated to high maternal and offspring risks. Hypoxemia was a predictive variable of poor maternal and fetal outcomes. Women with CCC should be advised against pregnancy, even when treated in specialized care centers.
- Vasopressin in septic shock: an individual patient data meta-analysis of randomised controlled trials(2019) NAGENDRAN, Myura; RUSSELL, James A.; WALLEY, Keith R.; BRETT, Stephen J.; PERKINS, Gavin D.; HAJJAR, Ludhmila; MASON, Alexina J.; ASHBY, Deborah; GORDON, Anthony C.PurposeWe performed an individual patient data meta-analysis to investigate the possible benefits and harms of vasopressin therapy in adults with septic shock both overall and in pre-defined subgroups.MethodsOur pre-specified study protocol is published on PROSPERO, CRD42017071698. We identified randomised clinical trials up to January 2019 investigating vasopressin therapy versus any other vasoactive comparator in adults with septic shock. Individual patient data from each trial were compiled. Conventional two-stage meta-analyses were performed as well as one-stage regression models with single treatment covariate interactions for subgroup analyses.ResultsFour trials were included with a total of 1453 patients. For the primary outcomes, there was no effect of vasopressin on 28-day mortality [relative risk (RR) 0.98, 95% CI 0.86-1.12] or serious adverse events (RR 1.02, 95% CI 0.82-1.26). Vasopressin led to more digital ischaemia [absolute risk difference (ARD) 1.7%, 95% CI 0.3%-3.2%] but fewer arrhythmias (ARD -2.8%, 95% CI -0.2% to -5.3%). Mesenteric ischaemia and acute coronary syndrome events were similar between groups. Vasopressin reduced the requirement for renal replacement therapy (RRT) (RR 0.86, 95% CI 0.74-0.99), but this finding was not robust to sensitivity analyses. There were no statistically significant interactions in the pre-defined subgroups (baseline kidney injury severity, baseline lactate, baseline norepinephrine requirement and time to study inclusion).ConclusionsVasopressin therapy in septic shock had no effect on 28-day mortality although the confidence intervals are wide. It appears safe but with a different side effect profile from norepinephrine. The finding on reduced RRT should be interpreted cautiously. Future trials should focus on long-term outcomes in select patient groups as well as incorporating cost effectiveness analyses regarding possible reduced RRT use.
- Microcirculation in Cardiovascular Diseases(2019) SLOVINSKI, Augusto Passoni; HAJJAR, Ludhmila Abrahao; INCE, CanMicrocirculation is a system composed of interconnected microvessels, which is responsible for the distribution of oxygenated blood among and within organs according to regional metabolic demand. Critical medical conditions, e.g., sepsis, and heart failure are known triggers of microcirculatory disturbance, which usually develops early in such clinical pictures and represents an independent risk factor for mortality. Therefore, hemodynamic resuscitation aiming at restoring microcirculatory perfusion is of paramount importance. Until recently, however, resuscitation protocols were based on macrohemodynamic variables, which increases the risk of under or over resuscitation. The introduction of hand-held video-microscopy (HVM) into clinical practice has allowed real-time analysis of microcirculatory variables at the bedside and, hence, favored a more individualized approach. In the cardiac intensive care unit scenario, HVM provides essential information on patients' hemodynamic status, e.g., to classify the type of shock, to adequate the dosage of vasopressors or inotropes according to demand and define safer limits, to guide fluid therapy and red blood cell transfusion, to evaluate response to treatment, among others. Nevertheless, several drawbacks have to be addressed before HVM becomes a standard of care.

METHODS We conducted a pragmatic, multicenter, single-blind, controlled trial at 36 centers in 13 countries. Patients scheduled to undergo elective CABG were randomly assigned to an intraoperative anesthetic regimen that included a volatile anesthetic (desflurane, isoflurane, or sevoflurane) or to total intravenous anesthesia. The primary outcome was death from any cause at 1 year. RESULTS A total of 5400 patients were randomly assigned: 2709 to the volatile anesthetics group and 2691 to the total intravenous anesthesia group. On-pump CABG was performed in 64% of patients, with a mean duration of cardiopulmonary bypass of 79 minutes. The two groups were similar with respect to demographic and clinical characteristics at baseline, the duration of cardiopulmonary bypass, and the number of grafts. At the time of the second interim analysis, the data and safety monitoring board advised that the trial should be stopped for futility. No significant difference between the groups with respect to deaths from any cause was seen at 1 year (2.8% in the volatile anesthetics group and 3.0% in the total intravenous anesthesia group; relative risk, 0.94; 95% confidence interval [CI], 0.69 to 1.29; P=0.71), with data available for 5353 patients (99.1%), or at 30 days (1.4% and 1.3%, respectively; relative risk, 1.11; 95% CI, 0.70 to 1.76), with data available for 5398 patients (99.9%). There were no significant differences between the groups in any of the secondary outcomes or in the incidence of prespecified adverse events, including myocardial infarction. CONCLUSIONS Among patients undergoing elective CABG, anesthesia with a volatile agent did not result in significantly fewer deaths at 1 year than total intravenous anesthesia.
- A Systematic Review and International Web-Based Survey of Randomized Controlled Trials in the Perioperative and Critical Care Setting: Interventions Reducing Mortality(2019) SARTINI, Chiara; LOMIVOROTOV, Vladimir; PIERI, Manna; LOPEZ-DELGADO, Juan Carlos; REDAELLI, Martina Baiardo; HAJJAR, Ludhmila; PISANO, Antonio; LIKHVANTSEV, Valery; FOMINSKIY, Evgeny; BRADIC, Nikola; CABRINI, Luca; NOVIKOV, Maxim; AVANCINI, Daniele; RIHA, Hynek; LEMBO, Rosalba; GAZIVODA, Gordana; PATERNOSTER, Gianluca; WANG, Chengbin; TAMA, Simona; ALVARO, Gabriele; WANG, Chew Yin; ROASIO, Agostino; RUGGERI, Laura; YONG, Chow-Yen; PASERO, Daniela; SEVERI, Luca; PASIN, Laura; MANCINO, Giuseppe; MURA, Paolo; MUSU, Mario; SPADARO, Savino; CONTE, Massimiliano; LOBREGLIO, Rosetta; SILVETTI, Simona; VOTTA, Carmine Domenico; BELLETTI, Alessandro; FRAJA, Diana Di; CORRADI, Francesco; BRUSASCO, Claudia; SAPORITO, Emanuela; D'AMICO, Alessandro; SARDO, Salvatore; ORTALDA, Alessandro; RIEFOLO, Claudio; FABRIZIO, Monaco; ZANGRILLO, Alberto; BELLOMO, Rinaldo; LANDONI, GiovanniThe authors aimed to identify interventions documented by randomized controlled trials (RCTs) that reduce mortality in adult critically ill and perioperative patients, followed by a survey of clinicians' opinions and routine practices to understand the clinicians' response to such evidence. The authors performed a comprehensive literature review to identify all topics reported to reduce mortality in perioperative and critical care settings according to at least 2 RCTs or to a multicenter RCT or to a single-center RCT plus guidelines. The authors generated position statements that were voted on online by physicians worldwide for agreement, use, and willingness to include in international guidelines. From 262 RCT manuscripts reporting mortality differences in the perioperative and critically ill settings, the authors selected 27 drugs, techniques, and strategies (66 RCTs, most frequently published by the New England Journal of Medicine [13 papers], Lancet [7], and Journal of the American Medical Association [5]) with an agreement >= 67% from over 250 physicians (46 countries). Noninvasive ventilation was the intervention supported by the largest number of RCTs (n = 13). The concordance between agreement and use (a positive answer both to ""do you agree"" and ""do you use"") showed differences between Western and other countries and between anesthesiologists and intensive care unit physicians. The authors identified 27 clinical interventions with randomized evidence of survival benefit and strong clinician support in support of their potential life-saving properties in perioperative and critically ill patients with noninvasive ventilation having the highest level of support. However, clinician views appear affected by specialty and geographical location.
- Vasopressin Versus Norepinephrine for the Management of Septic Shock in Cancer Patients: The VANCS II Randomized Clinical Trial*(2019) HAJJAR, Ludhmila Abrahao; ZAMBOLIM, Cristiane; BELLETTI, Alessandro; ALMEIDA, Juliano Pinheiro de; GORDON, Anthony C.; OLIVEIRA, Gisele; PARK, Clarice Hyesuk Lee; FUKUSHIMA, Julia Tizue; RIZK, Stephanie Itala; SZELES, Tais Felix; SANTOS NETO, Nestor Cordeiro dos; KALIL FILHO, Roberto; GALAS, Filomena Regina Barbosa Gomes; LANDONI, GiovanniObjectives: Previous trials suggest that vasopressin may improve outcomes in patients with vasodilatory shock. The aim of this study was to evaluate whether vasopressin could be superior to norepinephrine to improve outcomes in cancer patients with septic shock. Design: Single-center, randomized, double-blind clinical trial, and meta-analysis of randomized trials. Setting: ICU of a tertiary care hospital. Patients: Two-hundred fifty patients 18 years old or older with cancer and septic shock. Interventions: Patients were assigned to either vasopressin or norepinephrine as first-line vasopressor therapy. An updated meta-analysis was also conducted including randomized trials published until October 2018. Measurements and Main Results: The primary outcome was all-cause mortality at 28 days after randomization. Prespecified secondary outcomes included 90-days all-cause mortality rate; number of days alive and free of advanced organ support at day 28; and Sequential Organ Failure Assessment score 24 hours and 96 hours after randomization. We also measure the prevalence of adverse effects in 28 days. A total of 250 patients were randomized. The primary outcome was observed in 71 patients (56.8%) in the vasopressin group and 66 patients (52.8%) in the norepinephrine group (p = 0.52). There were no significant differences in 90-day mortality (90 patients [72.0%] and 94 patients [75.2%], respectively; p = 0.56), number of days alive and free of advanced organ support, adverse events, or Sequential Organ Failure Assessment score. Conclusions: In cancer patients with septic shock, vasopressin as first-line vasopressor therapy was not superior to norepinephrine in reducing 28-day mortality rate.
