RESUMO
OBJECTIVES: Severe acute kidney injury (AKI) requiring postoperative renal replacement therapy (RRT) is associated with increased morbidity and mortality rate following cardiac surgery. Our study was aimed to analyze patients requiring postoperative RRT in a population undergoing isolated coronary artery surgery. METHODS: Following exclusions, we analyzed 124,944 consecutive patients in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry), scheduled for isolated coronary artery surgery between January 2010 and December 2019. Patients who underwent preoperative chronic dialysis were excluded from the study. Data of patients requiring postoperative RRT and patients without postoperative RRT were compared. RESULTS: In the analyzed population, 1,668 patients (1.3%) developed AKI requiring RRT. In-hospital mortality among patients with and without postoperative RRT were 40.1% and 1.6%, respectively (P<0.001). Patients requiring postoperative RRT had significantly more preoperative co-morbidities and more frequent postoperative complications. Preoperative chronic renal failure and cardiogenic shock were the two most prominent independent risk factors for postoperative RRT in these patients (OR: 5.0, 95%CI: 3.9-6.4, P<0.001 and OR: 3.9, 95%CI: 2.8-5.6, P<0.001, respectively). CONCLUSION: Severe acute kidney injury (AKI) requiring postoperative RRT dramatically increases in-hospital mortality and is associated with the development of serious postoperative complications. The need for postoperative RRT is clearly associated with the presence of preoperative co-morbidities. Preoperative chronic renal failure and cardiogenic shock were particularly related with the development of this complication.
RESUMO
CONTEXT.: Extracorporeal membrane oxygenation (ECMO) is increasingly used in the treatment of respiratory and cardiac failure, but data describing lung histopathology in ECMO recipients are limited. OBJECTIVE.: To examine pulmonary histopathologic findings in patients who underwent venovenous (VV) ECMO for pulmonary reasons, or venoarterial (VA) ECMO for cardiac indications shortly before death, and to determine if the pulmonary changes provided insights into therapy that may prevent complications and improve outcome. DESIGN.: We conducted a retrospective study of lung autopsies, from VV and VA ECMO recipients and patients with acute respiratory distress syndrome (ARDS) and non-ECMO treatment, between 2008 and 2020 in Silesia Center for Heart Diseases in Zabrze, Poland. RESULTS.: Among 83 ECMO patients (42-64 years; male, 57 [68.7%]), the most common histopathologic findings were bronchopneumonia (44 [53.0%]), interstitial edema (40 [48.2%]), diffuse alveolar damage (DAD; 32 [38.6%]), hemorrhagic infarct (28 [33.7%]), and pulmonary hemorrhage (25 [30.1%]). DAD was associated with longer ECMO treatment and longer hospital stay. The use of VV ECMO was a predictor of DAD in patients with ARDS and undergoing ECMO, but it also occurred in 21 of 65 patients (32.3%) in the VA ECMO group, even though VA ECMO was used for heart failure. CONCLUSIONS.: Although DAD was significantly more common in lung autopsies of VV ECMO patients, one-third of VA ECMO patients had histopathologic changes characteristic of ARDS. The presence of DAD in lung autopsies of patients treated with VA ECMO indicates that in these patients, protective lung ventilation should be considered.
RESUMO
INTRODUCTION: Lactate levels have been recognized as a reliable tool for monitoring critically ill patients requiring venoarterial extracorporeal membrane oxygenation (VA ECMO) or venovenous extracorporeal membrane oxygenation (VV ECMO) but the reasons behind the overproduction of lactate are different and the influance for survival remains controversial. We analyzed the lactate values and lactate clearance in adult patients in these two forms of extracorporeal support. METHODS: Patient demographics, ECMO duration, 30-day mortality, lactate values and lactate clearance at 24, 48 and 72 h from ECMO initiation of patients supported with VV and VA ECMO at Silesian Centre for Heart Deasese, between January 2011 and April 2020 were retrospectively analyzed. The changes in lactate levels were analyzed using the non-parametric U Mann-Whitney tests and Chi-square test. The ROC curves were draw and the area under the curve was calculated. RESULTS: The study comprised 91 adult patients, Mortality in the first 30 days from initiation of VV and VA ECMO was 39% and 66%, respectively. Lactate levels were significantly higher in non-survivors that received VV and VA ECMO (p < .001), while lactate clearance was similar (p = .256 and p = 1.000, respectively). Survival curves for patients with elevated (>2.0 mmol/L) vs normal (≤2.0 mmol/L) lactate levels at 72 h were significantly different for VV ECMO (p = .007) and VA ECMO (p = .037) but in both groups of ECMO, lactate levels above 2.0 mmol/L at 72 h from ECMO initiation predicted 30 day-mortality. CONCLUSION: This results emphasized the importance of lactate levels below 2.0 mmol/L at 72 h from both VV and VA ECMO initiation.

BACKGROUND: This single-centre study investigated factors influencing death in coronavirus disease 2019 (COVID-19) patients treated in an intensive care unit (ICU). METHODS: Data of 113 consecutive patients with a severe form of COVID-19 infection, who completed their ICU stay in a large COVID-19-dedicated hospital in the Silesian Region of Poland during one year of the pandemic (between 10 March, 2020 and 10 March, 2021), were reviewed. Comprehensive comparison of all available ICU pre-admission, admission and treatment variables was performed. Variables that independently influenced ICU death were identified. RESULTS: ICU mortality in the whole group was 64.6%. Mean age was higher in non-survivors (64.6 ± 9.5 vs. 60.0 ± 12.8 years, P = 0.036), but the distribution of sex and body mass index was similar in both groups. Non-survivors had a marginally higher mean Charlson Comorbidity Index (5.9 ± 3.6 vs. 4.5 ± 4.1 points, P = 0.063), and significantly higher mean Clinical Frailty Score (4.8 ± 1.5 vs. 3.9 ± 1.4 points, P = 0.004), admission APACHE II score (22.9 ± 7.9 vs. 19.1 ± 7.8 points, P = 0.017) and SAPS II score (62.1 ± 18.1 vs. 54.0 ± 16.7 points, P = 0.023). Factors that independently influenced ICU death were limited to: admission total protein 2.0 ng mL-1 (OR = 11.3, P = 0.026) and lactate level > 2.0 mmol L-1 (OR = 4.2, P = 0.003) as well as Clinical Frailty Score ≥ 5 points (OR = 3.1, P = 0.021). CONCLUSIONS: The presence of low total protein, frailty and increased procalcitonin and lactate levels at ICU admission are associated with ICU death in patients with severe COVID-19 infection.

Analysis of patients with alcohol dependence (AD) treated in intensive care units has never been performed in Poland. Data from 25,416 adult patients identified in a Silesian Registry of Intensive Care Units were analysed. Patients with AD were identified, and their data were compared with the remaining population. Preadmission and admission variables that independently influenced ICU death in these patients were identified. Among 25,416 analysed patients, 2285 subjects (9.0%) were indicated to have AD among their comorbidities. Patients with AD were significantly younger (mean age: 53.3 ± 11.9 vs. 62.2 ± 15.5 years, p < 0.001) but had a higher mean APACHE II score at admission and were more frequently admitted to the ICU due to trauma, poisonings, acute pancreatitis, and severe metabolic abnormalities. ICU death and unfavourable outcomes were more frequent in these patients (47.8% vs. 43.0%, p < 0.001 and 54.1% vs. 47.0%, p < 0.001, respectively). Multiorgan failure as the primary cause of ICU admission was among the most prominent independent risk factors for ICU death in these patients (OR: 3.30, p < 0.001). Despite the younger age, ICU treatment of patients with AD was associated with higher mortality and a higher percentage of unfavourable outcomes.

BACKGROUND: Lung transplantation remains the only feasible option for certain patients with end-stage lung disease. Lifelong immunosuppression increases the risk of infection, including fungal infections. The aim of this study was to assess the effect of antifungal prophylaxis and treatment among lung transplant recipients in the early postoperative stage. METHODS: This retrospective analysis included 127 patients who underwent lung transplantation between 2014 and 2021 in the lung transplant ward, 65.35% of whom were males. The most common indication for lung transplantation was cystic fibrosis (n = 59; 46.46%). All of the patients were receiving inhaled amphotericin B. Within this group there were patients who also were treated with intravenous caspofungin, intravenous/oral voriconazole, or both. RESULTS: The difference in the efficacy against Candida spp. between caspofungin and voriconazole in the early post-transplant period was not statistically significant (χ2 = 0.5, P = .477). Moreover, the difference in the efficacy against Candida spp. between itraconazole and voriconazole during the first post-transplant year was not statistically significant (χ2 = 0.46, P = .496). CONCLUSION: Caspofungin and voriconazole are proper and relatively efficient antifungal prophylaxis and treatment options after lung transplantation. There was no significant difference between voriconazole and caspofungin as antifungal agents used in the early post-transplant stage. There was no significant difference between voriconazole and itraconazole as antifungal agents used during the first post-transplant year. Further research on this issue is required.

BACKGROUND: Life-long immunosuppression after lung transplantation increases the risk of bacterial infections, hence broad-spectrum antibiotics can be implemented after transplant. The aim of this study is to assess various aspects of bacterial infections in the early postoperative stage among lung transplant recipients on broad-spectrum antibiotics at a single center. METHODS: This retrospective study consists of 134 primary lung transplant recipients transplanted between 2014 and 2021 at a single center. Study analyzed the occurrence of de novo bacterium in bronchoalveolar lavage sampled 2 to3 weeks after lung transplantation, as well as survival and the occurrence of bacterial sepsis. Studied antibiotics include linezolid, meropenem, tobramycin, and cloxacillin. RESULTS: None of the patients from the broad-spectrum antibiotics developed bacterial sepsis within the first 30 postoperative days. In-hospital mortality due to bacterial sepsis among patients in the broad-spectrum group was 1.89%. The most common new pathogen in first couple of days after lung transplantation was Burkholderia multivorans (42%). After its occurrence, Ceftazidime was administered. It significantly reduced the occurrence of hospital-acquired B multivorans after 2 to 3 weeks post-transplant (χ2 = 8.01, P = .005). CONCLUSION: Broad-spectrum antibiotics seem to be an efficient approach against bacterial infections for lung transplant recipients in the early post-transplant period, as patients treated this way very rarely develop fatal bacterial infections in the studied period. Ceftazidime proved efficient for treatment for B multivorans among the studied group. Patients, who acquired new pathogen during post-transplant hospital stay presented comparable lung function at discharge in comparison to those who were not.

BACKGROUND: In Poland, the clinical characteristics and outcomes of patients with COVID-19 requiring extracorporeal membrane oxygenation (ECMO) remain unknown. This study aimed to answer these unknowns by analyzing data collected from high-volume ECMO centers willing to participate in this project. METHODS: This retrospective, multicenter cohort study was completed between March 1, 2020, and May 31, 2021 (15 months). Data from all patients treated with ECMO for COVID-19 were analyzed. Pre-ECMO laboratory and treatment data were compared between non-survivors and survivors. Independent predictors for death in the intensive care unit (ICU) were identified. RESULTS: There were 171 patients admitted to participating centers requiring ECMO for refractory hypoxemia due to COVID-19 during the defined time period. A total of 158 patients (mean age: 46.3 ± 9.8 years) were analyzed, and 13 patients were still requiring ECMO at the end of the observation period. Most patients (88%) were treated after October 1, 2020, 77.8% were transferred to ECMO centers from another facility, and 31% were transferred on extracorporeal life support. The mean duration of ECMO therapy was 18.0 ± 13.5 days. The crude ICU mortality rate was 74.1%. In the group of 41 survivors, 37 patients were successfully weaned from ECMO support and four patients underwent a successful lung transplant. In-hospital death was independently associated with pre-ECMO lactate level (OR 2.10 per 1 mmol/L, p = 0.017) and BMI (OR 1.47 per 5 kg/m2, p = 0.050). CONCLUSIONS: The ICU mortality rate among patients requiring ECMO for COVID-19 in Poland was high. In-hospital death was independently associated with increased pre-ECMO lactate levels and BMI.

PURPOSE: A significant percentage of patients are discharged from intensive care units (ICU) with disorders of counciousness (DoC). The aim of this retrospective, case-control study was to compare patients discharged from the ICU in a vegetative state (VS) or minimally conscious state (MCS) and the rest of ICU survivors, and to identify independent predictors of DoC among ICU survivors. METHODS: Data from 14,368 adult ICU survivors identified in a Silesian Registry of Intensive Care Units (active in the Silesian Region of Poland between October 2010 and December 2019) were analyzed. Patients discharged from the ICU in a VS or MCS were compared to the remaining ICU survivors. Pre-admission and admission variables that independently influence ICU discharge with DoC were identified. RESULTS: Among the 14,368 analyzed adult ICU survivors, 1,064 (7.4%) were discharged from the ICU in a VS or MCS. The percentage of patients discharged from the ICU with DoC was similar in all age groups. Compared to non- DoC ICU patients, they had a higher mean APACHE II and SAPS III score at admission. Independent variables affecting ICU discharge with DoC included unconsciousness at ICU admission, cardiac arrest and craniocerebral trauma as primary cause of ICU admission, as well as a history of previous chronic neurological disorders and cerebral stroke (p<0.001). CONCLUSION: Discharge in a VS and MCS was relatively frequent among ICU survivors. Discharge with DoC was more likely among patients who were unconscious at admission and admitted to the ICU due to cardiac arrest or craniocerebral trauma.

BACKGROUND Data on the outcomes of patients with coronavirus disease 2019 (COVID-19) requiring Intensive Care Unit (ICU) care in Poland are limited. There are no data on critically ill patients with COVID-19 who did not meet criteria for ICU admission. MATERIAL AND METHODS We analyzed patients admitted to the ICU and those ineligible for ICU admission in a large COVID-19-dedicated hospital, during the first 3 months of the pandemic in Poland. Data from 67 patients considered for ICU admissions due to COVID-19 infection, treated between 10 March and 10 June 2020, were reviewed. Following exclusions, data on 32 patients admitted to the ICU and 21 patients ineligible for ICU admission were analyzed. RESULTS In 38% of analyzed patients, symptoms of COVID-19 infection occurred during a hospital stay for an unrelated medical issue. The mean age of ICU patients was 62.4 (10.4) years, and the majority of patients were male (69%), with at least one comorbidity (88%). The mean admission APACHE II and SAPS II scores were 20.1 (8.1) points and 51.2 (15.3) points, respectively. The Charlson Comorbidity Index and Clinical Frailty Scale were lower in ICU patients compared with those disqualified: 5.9 (4.3) vs. 9.1 (3.5) points, P=0.01, and 4.7 (1.7) vs. 6.9 (1.2) points, P<0.01, respectively. All ICU patients required intubation and mechanical ventilation. ICU mortality was 67%. Hospital mortality among patients admitted to the ICU and those who were disqualified was 70% and 79%, respectively. CONCLUSIONS Patients with COVID-19 requiring ICU admission in our studied population were frail and had significant comorbidities. The outcomes in this group were poor and did not seem to be influenced by ICU admission.

BACKGROUND: According to the medical literature, both on-pump and off-pump coronary artery surgery is safe and effective in octogenarians. OBJECTIVES: The aim of our study was to examine the epidemiology, in-hospital outcomes and long-term follow-up results in octogenarians undergoing off-pump and on-pump coronary artery surgery utilizing nationwide registry data. METHODS: All octogenarians (≥ 80 years) enrolled in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry), who underwent isolated coronary surgery between January 2006 and September 2017 were identified. Preoperative data, perioperative complications, hospital mortality and long-term mortality were analyzed. Unadjusted and propensity-matched comparisons were performed between octogenarians undergoing off-pump and on-pump coronary artery bypass surgery. RESULTS: Octogenarians accounted for 4.1% of the total population undergoing coronary artery surgery in Poland during the analyzed period (n = 152,631) and this percentage is increasing. Among 6,006 analyzed patients, 2,744 (45.7%) were operated on-pump and 3,262 (54.3%) were operated off-pump. Propensity-matched analysis revealed that patients operated on-pump were more often reoperated due to postoperative bleeding and their in-hospital mortality was higher (6.6% vs 4.5%, p = 0.006 and 8.7% vs 5.8%, p = 0.001, respectively). Long-term all-cause mortality was lower among patients operated off-pump (p = 0.013). CONCLUSION: On the basis of our findings we suggest that off pump technique should be considered as perfectly acceptable in octogenarians.

INTRODUCTION: The postmortem interrogation of cardiac implantable electronic devices (CIEDs) has not been regularly practiced yet. We presumed that it can provide data not only on the mechanism of the patient's death but also on possible device malfunctions contributing to its occurrence. OBJECTIVES: The study aimed to determine the usefulness of the explantation and interrogation of CIEDs after the patient's death in routine clinical practice, when combined with autopsy findings and clinical followup starting from the time after device implantation. PATIENTS AND METHODS: Between August 24, 2008 and August 30, 2018, all patients who underwent autopsy in the tertiary cardiovascular center or partner facilities had the device explanted and interrogated by the qualified electrophysiologist. Clinical characteristics obtained at the time of device implantation and patients' death were obtained from medical records. Device interrogation results were then combined with autopsy report and clinical data. RESULTS: Out of 1200 autopsied patients, the device was removed and analyzed in 61 individuals. Clinical characteristics from the time of implantation and patients' death were available in 53 (86.7%) and 49 (80.3%) patients, respectively. Devicerelated concerns, undetected during patients' hospital stay, were noted in 6 cases (6.1%) and included 3 programming and 3 hardware issues. CONCLUSIONS: To our knowledge, this is the first study to date to combine the clinical followup of patients before death and on admission at the end of life, autopsy results, and postmortem CIED interrogation. Having implemented the device interrogation, we found 6 CIEDrelated events potentially associated with patients' death, which were not detected before its occurrence.

The current investigation aimed to evaluate long-term survival in patients undergoing isolated and combined coronary artery bypass grafting (CABG) with concomitant surgical ablation for atrial fibrillation (AF). Procedural data from KROK (Polish National Registry of Cardiac Surgery Procedures) were retrospectively collected. Eleven thousand three hundred sixteen patients with baseline AF (72.4% men, mean age 69.6 ± 7.9) undergoing isolated and combined CABG surgery between 2006-2019 in 37 reference centers across Poland and included in the registry were analyzed. The median follow-up was four years (3.7 IQR 1.3-6.8). Over a 12-year study period, there was a significant survival benefit (Hazard Ratio (HR) 0.83; (95% Confidence Interval (CI): 0.73-0.95); p = 0.005) with concomitant ablation as compared to no concomitant ablation. After rigorous propensity matching (LOGIT model, 432 pairs), concomitant surgical ablation was associated with over 25% improved survival in the overall analysis: HR 0.74; (95% CIs: 0.56-0.98); p = 0.036. The benefit of concomitant ablation was maintained in the subgroups, yet the most benefit was appraised in low-risk patients (EuroSCORE < 2, p = 0.003) with the three-vessel disease (p < 0.001) and without other comorbidities. Ablation was further associated with significantly improved survival in patients undergoing CABG with mitral valve surgery (HR 0.62; (95% CIs: 0.52-0.74); p < 0.001) and in patients in whom complete revascularization was not achieved: HR 0.43; (95% CIs: 0.24-0.79); p = 0.006.
RESUMO
BACKGROUND: No single randomized study has ever before addressed the safety of On-Pump coronary artery bypass grafting (CABG) vs Off-Pump CABG in the setting of atrial fibrillation (AF) and data from small observational samples remain inconclusive. METHODS AND FINDINGS: Procedural data from KROK (Polish National Registry of Cardiac Surgery Procedures) were retrospectively collected. Of initial 188,972 patients undergoing CABG, 7,913 presented with baseline AF (76.0% men, mean age 69.1±8.2) and underwent CABG without concomitant valve surgery between 2006-2019 in 37 reference centers across Poland. Mean follow-up was 4.7±3.5 years (median 4.3 IQR 1.7-7.4). Cox proportional hazards models were used for computations. Of included patients, 3,681 underwent On-Pump- (46.52%) as compared to 4,232 (53.48%) who underwent Off-Pump CABG. Patients in the latter group less frequently were candidates for complete revascularization (P<0.001). In an unadjusted comparison, On-Pump surgery was associated with significantly worse survival at 30 days: HR: 1.28; 95%CIs: (1.07-1.53); P = 0.007. Along the 13-year study period, the trend shifted in favor of On-Pump CABG: HR: 0.92; 95%CIs: (0.83-0.99); P = 0.005. After rigorous propensity matching, 636 pairs were identified. The direction and magnitude of treatment effects was sustained with HRs of 3.58; (95%CIs: 1.34-9.61); p = 0.001 and 0.74; [95%CIs: 0.56-0.98]; p = 0.036) for 30-day and late mortality respectively. CONCLUSIONS: Off-Pump CABG offered 30-day survival benefit to patients undergoing CABG surgery and presenting with underlying AF. On-Pump CABG was associated with significantly improved survival at long term.

BACKGROUND: Various factors can contribute to high mortality rates in intensive care units (ICUs). Here, we intended to define a population of patients readmitted to general ICUs in Poland and to identify independent predictors of ICU readmission. METHODS: Data derived from adult ICU admissions from the Silesian region of Poland were analyzed. First-time ICU readmissions (≤30 days from ICU discharge after index admissions) were compared with first-time ICU admissions. Pre-admission and admission variables that independently influenced the need for ICU readmission were identified. RESULTS: Among the 21,495 ICU admissions, 839 were first-time readmissions (3.9%). Patients readmitted to the ICU had lower mean APACHE II (21.2 ± 8.0 vs. 23.2 ± 8.8, p < 0.001) and TISS-28 scores (33.7 ± 7.4 vs. 35.2 ± 7.8, p < 0.001) in the initial 24 h following ICU admission, compared to first-time admissions. ICU readmissions were associated with lower mortality vs. first-time admissions (39.2% vs. 44.3%, p = 0.004). Independent predictors for ICU readmission included the admission from a surgical ward (among admission sources), chronic respiratory failure, cachexia, previous stroke, chronic neurological diseases (among co-morbidities), and multiple trauma or infection (among primary reasons for ICU admission). CONCLUSIONS: High mortality associated with first-time ICU admissions is associated with a lower mortality rate during ICU readmissions.

INTRODUCTION: Mortality in Polish intensive care units (ICU) is excessively high. Only a few patients do not require intubation and invasive ventilation throughout the whole ICU treatment period. We aimed to define this population, as pre-emptive admissions of such patients may increase the population which benefits from ICU admission and reduce excessive mortality in Polish ICUs. MATERIAL AND METHODS: Data on 20 651 patients from the Silesian Registry of Intensive Care Units were analysed. Patients who did not require intubation and invasive ventilation (referred to as non-ventilated patients) were identified and compared to the remaining ICU population. Independent variables that influence being non-intubated in the ICU were identified. RESULTS: Among 20 368 analyzed adult patients, only 1233 (6.1%) were in the non-ventilated group. Non-ventilated patients were younger, with fewer comorbidities and a lower APACHE II score at admission (13.0 ±7.1 vs. 23.7 ±8.6 points, p < 0.001). Patients with cardiac arrest prior to admission were particularly rare in this group (2.6% vs. 26.8%, p < 0.001). The ICU mortality among non-ventilated patients was 6 to 7 times lower (7.0% vs. 46.7%, p < 0.001). Independent variables that influenced the ICU stay in non-ventilated patients were: obstetric complications as the primary cause of ICU admission, presence of a systemic autoimmune disease, invasive monitoring as the primary cause of ICU admission, ICU readmission and the presence of cancer. CONCLUSIONS: Non-ventilated patients have a high potential for a favourable outcome. Preemptive ICU admissions have a potential to reduce mortality in Polish ICUs.
RESUMO
Extracorporeal membrane oxygenation (ECMO) is a technique involving oxygenation of blood and elimination of carbon dioxide in patients with life-threatening, but potentially reversible conditions. Thanks to the modification of extracorporeal circulation used during cardiac surgeries, this technique can be used in intensive care units. Venovenous ECMO is used as a respiratory support, while venoarterial ECMO as a cardiac and/or respiratory support. ECMO does not cure the heart and/or lungs, but it gives the patient a chance to survive a period when these organs are inefficient. In addition, extracorporeal membrane oxygenation reduces or eliminates the risk of lung damage associated with invasive mechanical ventilation in patients with severe ARDS (acute respiratory distress syndrome). ECMO is a very invasive therapy, therefore it should only be used in patients with extremely severe respiratory failure, who failed to respond to conventional therapies. According to the Extracorporeal Life Support Organization (ELSO) Guidelines, inclusion criteria are: PaO2 / FiO2 < 80 for at least 3 hours or pH < 7.25 for at least 3 hours. Proper ECMO management requires advanced medical care. This article discusses the history of ECMO development, clinical indications, contraindications, clinical complications and treatment outcomes.
