RESUMEN
Discovery of CARF (Collaborator of ARF)/CDKN2AIP as an ARF-interacting protein that promotes ARF-p53-p21WAF1 signaling and cellular senescence, initially established its role in genomic stress. Multiple reports further unraveled its role in regulation of senescence, growth arrest, apoptosis, or malignant transformation of cells in response to a variety of stress conditions in cultured human cells. It has been established as an essential protein. Whereas CARF-compromised cells undergo apoptosis, its enrichment has been recorded in a variety of cancer cells and has been associated with malignant transformation. We earlier demonstrated its role in stress-induced cell phenotypes that ranged from growth arrest, apoptosis, or malignant transformation. In the present study, we assessed the molecular mechanism of quantitative impact of change in CARF expression level on these cell fates. Stress-induced changes in CARF expression were assessed quantitatively with proteins involved in proteotoxicity, oxidative, genotoxic, and cytotoxic stress. These comparative quantitative analyses confirmed that (i) CARF responds to diverse stresses in a quantitative manner, (ii) its expression level serves as a reliable predictive measure of cell fates (iii) it correlates more with the DNA damage and MDA levels than the oxidative and proteotoxic signatures and (iv) CARF-expression based quantitative assay may be recruited for stress diagnostic applications.

Acute coronary syndrome (ACS) is a leading cause of mortality worldwide. Despite optimal antiplatelet therapy recommendation after ischemic events, recurrent thrombotic complications rate remains high. The recurrent events maybe in part due to increased thrombin levels during ACS which may underscore the need for an additional anticoagulation therapy. Given the advantages of non-vitamin K antagonist oral anticoagulants (NOACs) over warfarin, they have the potential to prevent thrombus formation, in the presence or absence of atrial fibrillation, but at the cost of increased risk of bleeding. NOACs have also shown a promising efficacy in managing left ventricular thrombus and a potential benefit in avoiding stent thrombosis after percutaneous coronary revascularization. Taken as a whole, NOACs are increasingly used for off-licence indications, and continue to evolve as essential therapy in preventing and treating thrombotic events. Herein, this review discusses NOACs off-label indications in the setting of ischemic coronary disease.
RESUMEN
INTRODUCTION: Off-pump coronary artery bypass grafting (OPCABG) was introduced many years ago aiming to reduce the known complications of conventional on-pump coronary surgeries. Heparin is required during the procedures, but the available protocols have diverse dosage regimens. The primary objective of this systematic review is to examine the effect of different heparin doses on the outcomes of OPCABG. EVIDENCE ACQUISITION: MEDLINE and EMBASE were searched. Four reviewers identified eligible clinical trials. Two reviewers extracted data and independently assessed the risk of bias using Cochrane tool. The primary outcome was the activated clotting time (ACT) at three minutes. The secondary outcomes were proportion of patients requiring blood products and the length of hospital stay. An aggregate data approach was used. EVIDENCE SYNTHESIS: Three single-center randomized studies recruiting 256 patients were included. The studies compared low-dose (1.5-2 mg/kg) and high-dose (3 mg/kg) heparin boluses. The overall mean difference for ACT after three minutes between low- and high-dose heparin is - 126.16 (95% CI: - 142.19, - 110.14). The proportion of patients requiring blood products after surgery [odd ratio 1.27 (95% CI: 0.69, 2.32)] or the overall length of stay [mean difference -0.15 (95% CI: -0.84, 0.53)] did not differ between the heparin doses. CONCLUSIONS: In OPCABG, high-dose compared with low-dose heparin did not affect the utilization of more blood products or increased the overall length of stay. Unsurprisingly, ACT values were higher in the high-dose heparin group. Larger and adequately powered randomized clinical trials are indicated to resolve the uncertainty.
RESUMEN
OBJECTIVES: We aim at identifying the changes in venous blood saturation values that associates intra-aortic balloon pump (IABP) in cardiac surgery patients with reduced left ventricular function (LVF). METHODS: A retrospective observational study was conducted in a cardiothoracic intensive care unit (CTICU) in a tertiary cardiac center over 5 years in Qatar. A total of 114 patients with at least moderate impairment of LVF with ejection fraction (EF) less than 40% were enrolled. According to the association of IABP, patients were segregated into two groups with and without IABP (groups 1, 40 patients and group 2, 74 patients). Sequential arterial and venous blood gases were analyzed. The primary outcome was to analyze the changes in the central venous saturation (ScvO2) in both groups and the secondary outcome was to analyze whether these changes affect the overall outcome in terms of intensive care unit (ICU) length of stay. RESULTS: There was no significant difference between both groups with regard to age, preoperative EF, hemoglobin, and arterial oxygen saturation (SaO2) in blood gases. Patients with IABP have a higher cScvO2 when compared to the other group (71.5 ± 12.5 vs 63.5 ± 9.3, 68.3 ± 12.6 vs 60.1 ± 9.5, 62.7 ± 10.8 vs 55.63 ± 8.1, and 60.6 ± 7.6 vs 54.9 ± 8.1; p = 0.04, 0.05, 0.03, and 0.5, respectively). However, generalized estimating equations (GEE) analysis showed that compared with the participants showing that there is a decreasing trend in mean levels within the groups during follow-ups, overall difference between both groups' mean levels was not statistically significant. CONCLUSIONS: In this study, we observed that after cardiac surgeries, patients with IABP had non-significant higher ScvO2 when compared with a corresponding group with moderate impairment of LVF. Further prospective studies are required to validate these findings.

Despite the many accomplishments since the introduction of percutaneous dilational (PDT) tracheostomy, we continue to observe emerging complications as we forge ahead in intensive care practice. As a result of this, we provide a new technique that could avoid some complications, notably posterior tracheal wall injury, bronchoscopic or endotracheal tube puncture, and false track. The new technology was evaluated on a 75-year-old Caucasian male cadaver was selected for a novel PDT technique. A wire with a sharp terminal end passed through the bronchoscopic channel and punctured the trachea from inside towards the skin. The wire was pulled and directed towards the mediastinum. The rest of the technique was carried out like a routine procedure. The procedure was technically feasible; further clinical trials are required to confirm the validity of this technique.

We sought to synthesize the available evidence regarding safety and efficacy of intermittent levosimendan (LEVO) infusions in ambulatory patients with end-stage heart failure (HF). Safety and efficacy of ambulatory intermittent LEVO infusion in patients with end-stage HF are yet not established. We systematically searched MEDLINE, EMBASE, SCOPUS, Web of Science, and Cochrane databases, from inception to January 30, 2021 for studies reporting outcome of adult ambulatory patients with end-stage HF treated with intermittent LEVO infusion. Fifteen studies (8 randomized and 7 observational) comprised 984 patients (LEVO [N = 727] and controls [N = 257]) met the inclusion criteria. LEVO was associated with improved New York Heart Association (NYHA) functional class (weighted mean difference [WMD] -1.04, 95%CI: -1.70 to -0.38, p < 0.001, 5 studies, I2 = 93%), improved left ventricular (LV) ejection fraction (WMD 4.0%, 95%CI: 2.8% to 5.3%, p < 0.001, 6 studies, I2 = 9%), and reduced BNP levels (WMD -549 pg/mL, 95%CI -866 to -233, p < 0001, 3 studies, I2 = 66%). All-cause death was not different (RR 0.65, 95%CI: 0.38 to 1.093, p = 0.10, 6 studies, I2 = 0), but cardiovascular death was lower on LEVO (RR 0.34, 95%CI: 0.13 to 0.87, p = 0.02, 3 studies, I2 = 0) compared to controls. Furthermore, health-related quality of life (HRQoL) was improved alongside with reduced LV size following LEVO infusions. Major adverse events were not different between LEVO and placebo. In conclusion, intermittent LEVO infusions in ambulatory patients with end-stage HF is associated with less frequent cardiovascular death alongside with improved NYHA class, quality of life, BNP levels, and LV function. However, the current evidence is limited by heterogeneous and relatively small studies.

BACKGROUND: Burnout syndrome (BOS) is a job-related stress disorder featured by three main cardinal manifestations: emotional exhaustion (EE), reduced personal accomplishment (PA), and depersonalization (DP). AIM: We aimed to report the prevalence of burnout and the impact of leadership and work condition on the burnout among respiratory therapists (RT) are front-line practitioners in many critical settings. METHODS: We surveyed RT in eight intensive care units (ICU) at five tertiary hospitals, under one medical corporation, using three instruments: the Maslach Burnout Inventory Human Services Survey for Medical Personnel, Condition of Work Effectiveness Questionnaire (CWEQ), and Leadership behaviours scale. We used a group of other health care practitioners (ie, physicians and nurses) as the control group. RESULTS: Of a sampling frame of 1222 ICU practitioners, 445 (36.4%) responded with completed surveys. Eighty-four (17.3%) and 361 (82.7%) participants were in the RT and the control group, respectively. The overall burnout score was significantly lower in the RT group (53.6% vs. 67%, p = 0.02). The EE and DP scores were significantly lower in the RT group [(26.2% vs. 37.7, p = 0.048) and (9.5% vs. 19.9%, p = 0.025), respectively], but the PA score did not show significant difference between the groups. A significant negative relationship was found between CWEQ score and both EE and DP scores (rs = -0. 0.557, p < 0.001) and (rs = -0.372, p < 0.001), respectively, while a significant positive correlation was found between CWEQ and the PA score (rs = 0.225, p < 0.042). A significant negative relationship was found between the leadership attitude and EE scores (rs = -0.414, p < 0.001). CONCLUSION: The results of this study suggest a high burnout rate among RT. The reported rate was significantly correlated to work conditions and leadership behaviours. Organizational efforts should be directed to combating burnout through the identification and adequate management of the key precipitating factors. CLINICALTRIALS.GOV IDENTIFIER: NCT04620005.

OBJECTIVE: The aim was to look at the Cardiac Surgery Score (CASUS) assessment after cardiac surgery, and compare it with the intensive care unit (ICU) mortality and morbidity, in a racially diverse group of patients, in a single center. DESIGN: Clinical retrospective study analyzing data from 319 patients over a 1-year duration. SETTING: Cardiothoracic intensive care unit (CTICU) of a tertiary care center. PARTICIPANTS: All patients who underwent cardiac surgery between January 1 and December 31, 2017. INTERVENTIONS: Review of electronic patient records. MEASUREMENTS AND RESULTS: Daily CASUS assessments (calculated on an online application and recorded on patient electronic records) were retrieved. The variables of CASUS used for the study were CASUS value on postoperative day 1 (POD1-CASUS), on death/discharge from CTICU (Dis-CASUS), mean of all CASUS values during CTICU stay (M-CASUS), and differential CASUS (Dif- CASUS) [CASUS POD 1 - CASUS on discharge]. The receiver operating characteristic (ROC) curve for the diagnostic level of POD 1-CASUS, indicating mortality, was calculated. A value of >6.5 for POD 1 CASUS had 80% sensitivity and 84% specificity, with area under the curve value 0.756 (95% confidence interval: 0.46 to 1). The mean values of POD1-CASUS (8.6 ± 6), M-CASUS (8.2 ± 5.2), and Dis-CASUS (7.8 ± 5.7) were significantly higher in cases of mortality, compared to the others. POD1-CASUS, M-CASUS, and Dis-CASUS were found to be statistically significantly elevated in patients with acute kidney injury (AKI) and postoperative stroke, and in those who were readmitted to the CTICU after initial discharge. Patients with POD1-CASUS ≥6.5 had a statistically significant association with mortality and postoperative morbidity (p < 0.05). Findings from multivariate logistic regression indicated that body mass index (BMI), ICU readmission, length of mechanical ventilation, and length of ICU stay remained associated significantly with POD1 CASUS ≥6.5. CONCLUSION: This study found that CASUS on POD 1, mean values of CASUS during CTICU stay, and CASUS at death/discharge from CTICU predicted ICU mortality after cardiac surgery in this racially diverse group. The CASUS derivatives can be used to predict unfavorable outcomes after cardiac surgery. A POD1-CASUS value of 6.5 or more could signify mortality and postoperative morbidity.

OBJECTIVES: This study aimed at investigating the effects of an extracorporeal membrane oxygenation (ECMO) service on Burnout syndrome (BOS) development in the intensive care unit (ICU). DESIGN: The authors conducted a cross-sectional descriptive study. SETTINGS: Eight ICUs within 5 tertiary hospitals in 1 country. PARTICIPANTS: Intensive care practitioners (nurses, physicians, and respiratory therapists). INTERVENTION: Using an online questionnaire, the Maslach Burnout Inventory Human Services Survey for Medical Personnel. In addition, demographic variables, workload, salary satisfaction, and caring for COVID-19 patients were assessed. Participants were divided based on working in an ICU with ECMO (ECMO-ICU) and without (non-ECMO-ICU) ECMO service, and burnout status (burnout and no burnout). MEASUREMENTS AND MAIN RESULTS: The response rate for completing the questionnaire was 36.4% (445/1,222). Male patients represented 53.7% of the participants. The overall prevalence of burnout was 64.5%. The overall burnout prevalence did not differ between ECMO- and non-ECMO-ICU groups (64.5% and 63.7, respectively). However, personal accomplishment (PA) score was significantly lower among ECMO-ICU personnel compared with those in a non-ECMO-ICU (42.7% v 52.6, p = 0.043). Significant predictors of burnout included profession (nurse or physician), acquiring COVID-19 infection, knowing other practitioners who were infected with COVID-19, salary dissatisfaction, and extremes of workload. CONCLUSION: Burnout was equally prevalent among participants from ECMO- and non-ECMO-ICU, but PA was lower among participants in the ICU with an ECMO service. The reported high prevalence of burnout, and its predictors, requires special attention to try to reduce its occurrence.

Mechanical circulatory support (MCS) devices, especially veno-arterial extracorporeal membrane oxygenation (VA-ECMO) devices, are increasingly used to shore complex cardiac procedures in high-risk patients. We are reporting two cases where patients underwent coronary artery bypass grafting (CABG) under support of VA-ECMO in the setting of cardiogenic shock complicating acute myocardial infarction. The patients had different courses, but both survived the initial insult and were weaned successively from VA-ECMO. Our report indicates that VA-ECMO can be used instead of the cardiopulmonary bypass machine (CPB) to support the circulation during CABG surgery in patients with complex coronary anatomy and unstable haemodynamics. Future studies focusing on the long-term outcomes of such patients will probably help to establish the optimal management of this type of patients.

OBJECTIVES: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides a temporary support system for patients with cardiogenic shock refractory to conventional medical therapies. It has been reported that levosimendan may facilitate VA-ECMO weaning and improve survival. The primary objective of this review was to examine the effect of levosimendan use on VA-ECMO weaning and mortality in critically ill patients on VA-ECMO. DESIGN: MEDLINE, EMBASE, and CENTRAL were searched. A pair of reviewers identified eligible clinical trials. Two reviewers extracted data and independently assessed the risk of bias. A random-effect model was used to combine data. The primary outcome was the success of weaning from VA-ECMO. MEASUREMENTS AND MAIN RESULTS: Seven studies of observational design, including a total of 630 patients, were selected in the final analysis. The sample size ranged from ten-to-240 patients, with a mean age between 53 and 65 years, and more than half of them underwent cardiac surgeries. The VA-ECMO durations varied between four and 11.6 days. Overall, levosimendan use was significantly associated with successful weaning compared with control (odds ratio [OR] 2.89, 95% CI, 1.53-5.46; poverall effect = 0.001); I2â¯=â¯49%). For survival, six studies (nâ¯=â¯617) were included in the meta-analysis involving 326 patients in the levosimendan group and 291 in the comparator group. Pooled results showed a significantly higher survival rate in the levosimendan group (OR 0.46, 95% CI, 0.30-0.71; poverall effect = 0.0004; I2â¯=â¯20%). CONCLUSIONS: Levosimendan therapy was significantly associated with successful weaning and survival benefit in patients with cardiogenic or postcardiotomy shock needing VA-ECMO support for severe cardiocirculatory compromise. To date, there is limited literature and absence of evidence from randomized trials addressing the use of levosimendan in VA-ECMO weaning. This study may be considered a hypothesis-generating research for randomized controlled trials to confirm its findings.

Glucagon-like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors produce some beneficial and deleterious effects in diabetic patients not mediated by their glycemic lowering effects, and there is a need for better understanding of the molecular basis of these effects. They possess antioxidant and anti-inflammatory effects with some direct vasodilatory action (animal and human trial data) that may indirectly influence heart failure (HF). Unlike GLP-1R agonists, signaling for HF adverse effects was observed with two DPP-4 inhibitors, saxagliptin and alogliptin. Accordingly, these drugs should be used with caution in heart failure patients.

OBJECTIVES: Postoperative atrial fibrillation (POAF) remains a major risk after cardiac surgery. Twelve percent patients admitted to this unit postcardiac surgery experienced POAF, which led to hemodynamic instability, increased risk of stroke, and increased length of postoperative intensive care unit stay. Our aim was to decrease the incidence of POAF in the cardiothoracic intensive care unit by the end of April 2014. METHODS: Design-Retrospective data analysis. Settings-Postcardiac surgery intensive care in a tertiary hospital. PARTICIPANTS: Postcardiac surgery patients. Intervention-A clinical practice guideline (CPG) was developed to promote early prevention and to improve adherence to POAF prophylaxis recommendations. Patient's charts were our key performance indicator. Primary outcome measure-Percentage of patients who developed episodes of POAF within the first 24 hours of cardiac surgery. Process measures-compliance with the newly developed CPG and early postoperative patient assessment. Balance measure-early administration of ß-blocker. RESULTS: We were able to decrease POAF to 8% after intervention. Compliance with early assessment improved from 25% to 87%. Compliance with adherence to the CPG was 80%. Adherence to the newly developed paper form was the major challenge that could be overcome by an electronic form. We hope to decrease the incidence of POAF to 6% and develop an electronic form by the end of December 2014. CONCLUSION: This quality improvement project changed the strategy and succeeded in decreasing the incidence of POAF after cardiac surgery. It also improved early assessment of risk factors.

The purpose of this study was to evaluate the ability of radiographic densitometry in detecting the early demineralization of human enamel and cementum in irradiated and non-irradiated teeth. Sixty extracted teeth were divided into two groups: irradiated group and non-irradiated group. After irradiation, the groups were subjected to demineralization-remineralization (PH) cycling. Radiographic densitometric measurements (gray values) of a selected area of interest in the enamel and in the cementum of each tooth were performed at baseline and after PH cycling. After PH cycling, there was a significant reduction in gray values for both groups. The difference between "baseline" and "after PH cycling" values represents the reduction in the mineral content of the hard tissue, i.e., the demineralization. Results show that the demineralization of irradiated tooth enamel and cementum was significantly higher compared to that of non-irradiated tissues as determined by gray-level values. It is concluded that densitometric measurements by means of digital radiographs allow for the detection of demineralization of enamel and cementum, and can be used successfully for diagnosis of the early carious lesions in patients who received head and neck radiotherapy. This will allow implementation of remineralizing therapy and avoid the risk of progression of radiation caries. Furthermore, it is concluded that gamma irradiation with typical therapeutic doses for head and neck carcinoma is a direct cause of demineralization of tooth enamel and cementum.

BACKGROUND: The value of cardiac troponin as a risk assessment tool for cardiac disease in the setting of end-stage renal diseases (ESRD) is not equivalent to its value in those with normal renal function. This consideration had not been studied in settings of acute kidney injury (AKI). We aim to explore the diagnostic value of high sensitive troponin T (hsTnT) in the settings of cardiac surgery-induced AKI. METHODS: Single center observational retrospective study. Based on the AKI Network, patients divided into 2 groups, group I without AKI (259 patients) and group II with AKI (100 patients) where serial testing of hsTnT and creatine kinase (CK)-MB were followed in both groups. Patients with (ESRD) were excluded. RESULTS: The mean age in our study was 55.1 ± 10.2 years. High association of AKI (27.8%) was found in our patients. Both groups were matched regarding the age, gender, body mass index, the association of diabetes or hypertension, and Euro score. AKI group had significantly higher mortality 5% vs group I 1.1% (p = 0.03). The hsTnt showed a significant sustained rise in the AKI group as compared to the non-AKI group, however CK-MB changes were significant initially but not sustained. The AKI group was more associated with heart failure 17.9% vs 4.9% (p = 0.001); and post-operative atrial fibrillation, 12.4% vs 2.9% (p = 0.005). Lengths of ventilation, stays in ICU and in hospital were significantly higher in the AKI group. CONCLUSIONS: Unlike the CK-MB profile, the hsTnT showed significant changes between both groups all over the course denoting possible delayed clearance in patients with AKI.

BACKGROUND: The importance of optimal postoperative glycemic control in cardiac patients remains unclear. Various glycemic targets have been prescribed to reduce wound infection and overall mortality rates. AIM OF THE WORK: To assess glucose control, as determined by time in range (TIR), in patients with glycemic targets of 6.0 to 8.1 mmol/L, and to determine factors related to poor control. METHODS: This prospective descriptive study evaluated 227 consecutive patients, 100 with and 127 without diabetes, after cardiac surgery. Patients received insulin to target glucose concentrations of 6.0 to 8.1 mmol/L. Data analyzed included patient age, gender, race, Euro score, cardiopulmonary bypass time (CPB), aortic cross clamp time (ACC), length of ventilation, stay in the intensive care unit (ICU) and stay in the hospital. Patients were divided into two groups, those who maintained > 80% and < 80% TIR. Outcome variables were compared in diabetics and non-diabetics. RESULTS: Patients with >80% and <80% TIR were matched in age, sex, gender, and Euro score. Failure to maintain target glycemia was significantly more frequent in diabetics (p = 0.001), in patients with glycated hemoglobin (HbA1c) > 8% (p = 0.0001), and in patients taking dopamine (p = 0.04) and adrenaline (p = 0.05). Times of CPB and ACC, length of stay in the ICU and ventilation were significantly higher in patients with TIR <80% than >80%. Rates of hypoglycemia, acute kidney injury, and in-hospital mortality were similar in the two groups, although the incidence of wound infection was higher in patients with TIR <80%. Both diabetics and non-diabetics with low TIR had poorer outcomes, as shown by length of stay and POAF. No significant differences were found between the two ethnic groups (Arabs and Asians). CONCLUSION: Patients with >80% TIR, whether or not diabetics, had better outcomes than those with <80% TIR, as determined by wound infection, lengths of ventilation and ICU stay. Additionally, they were not subject to frequent hypoglycemic events. Preoperatively high HbA1C is likely a good predictor of poor glycemic control.

BACKGROUND: Dissatisfaction with the intensive care unit may threaten medical care. Clarifying treatment preferences can be useful in these settings, where physician direction may influence decision making and therefore medical treatment. This study aimed to evaluate whether fast-track discharge from intensive care units affects the satisfaction of family members. METHODS: We used a single-center non-randomized trial, with all eligible family members involved. To evaluate family satisfaction, we used the Society of Critical Care Family Needs Assessment questionnaire (SCCMFNAQ). We hypothesized that those discharged within 24 h of intensive care unit admission and their families would have higher levels of satisfaction. Patients were scored using the therapeutic interventions scoring system (TISS) and additive EuroSCORE. RESULTS: Two-hundred fifty-five family members were enrolled. The mean patient age was 53 years, and 92 % were male. The median satisfaction level among family members was 17.9 (range 14-31). Patients were divided into two groups, one receiving fast-track discharge (116 patients), and one whose members stayed longer (139 patients). The overall satisfaction was affected significantly by quality of the delivered care and dissatisfaction increased by lack of comfort in hospital settings, including the waiting room. No significant differences were seen between the two groups for overall satisfaction (p = 0.546) and individual components of the questionnaire. Higher satisfaction was linked to higher levels of education among family members (p = 0.045) and information being relayed by a senior physician p = 0.03 (two-tailed test). CONCLUSIONS: Fast-track discharge from intensive care did not influence family satisfaction as hypothesized. Satisfaction relied on family members' level of education and the level of seniority of the physician relaying information.

Several factors are implicated in the increased vulnerability of multiple trauma victims to infection, especially in intensive care units. The incidence of EVD related infections ranges from 5 to 20%. To assess the accuracy of serum procalcitonin (PCT) in predicting central nervous system (CNS) infection in patients with EVDs. Thirty-six adult patients with severe head trauma were enrolled in this prospective study, after exclusion of other causes of fever; patients were subjected to sampling of C-reactive protein (CRP), PCT, and cerebrospinal fluid (CSF) cultures every other day. Five patients developed ventriculostomy-related infections, and all had an elevated serum PCT concentration. Patients with negative CSF cultures had mean serum PCT <2.0 ng/ml, while patients with positive culture had early elevation of serum PCT with mean of 4.18 ng/ml, CRP did not show similar early changes. Patients who acquire CNS infection had prolonged length of stay in hospital and length of ventilation. In absence of other nosocomial infections, early high serum PCT concentrations appear to be a reliable indicator of bacterial CNS infection in patients with EVD.

BACKGROUND: Cardiac arrest remains a critical condition with high mortality and catastrophic neurological impact. Extracorporeal cardiopulmonary resuscitation (ECPR) has been introduced as an adjunct in cardiopulmonary resuscitation modalities. However, survival with good neurological outcomes remains a major concern. This study aims to explore our early experience with ECPR and identify the factors associated with survival in patients presenting with refractory cardiac arrest. METHODS: This is a retrospective cohort study analyzing 6-year data from a tertiary center, the country reference for ECPR. This study was conducted at a national center of ECPR. Participants of this study were adult patients who experienced witnessed refractory cardiopulmonary arrest and were supported by ECPR. ECPR was performed for eligible patients as per the local service protocols. RESULTS: Data from 87 patients were analyzed; of this cohort, 62/87 patients presented with in-hospital cardiac arrest (IHCA) and 25/87 presented with out-of-hospital cardiac arrest (OHCA). Overall survival to decannulation and hospital discharge rates were 26.4% and 25.3%, respectively. Among survivors (n = 22), 19 presented with IHCA (30.6%), while only 3 survivors presented with OHCA (12%). A total of 15/87 (17%) patients were alive at 6-month follow-up. All survivors had good neurological function assessed as Cerebral Performance Category 1 or 2. Multivariate logistic regression to predict survival to hospital discharge showed that IHCA was the only independent predictor (odds ratio: 5.8, P = 0.042); however, this positive association disappeared after adjusting for the first left ventricular ejection fraction after resuscitation. CONCLUSIONS: In this study, the use of ECPR for IHCA was associated with a higher survival to discharge compared to OHCA. This study demonstrated a comparable survival rate to other established centers, particularly for IHCA. Neurological outcomes were comparable in both IHCA and OHCA survivors. However, large multicenter studies are warranted for better understanding and improving the outcomes.
