RESUMO
INTRODUCTION: Prognostication of outcome in severe stroke patients necessitating invasive mechanical ventilation poses significant challenges. The objective of this study was to assess the prognostic significance and prevalence of early electroencephalogram (EEG) abnormalities in adult stroke patients receiving mechanical ventilation. METHODS: This study is a pre-planned ancillary investigation within the prospective multicenter SPICE cohort study (2017-2019), conducted in 33 intensive care units (ICUs) in the Paris area, France. We included adult stroke patients requiring invasive mechanical ventilation, who underwent at least one intermittent EEG examination during their ICU stay. The primary endpoint was the functional neurological outcome at one year, determined using the modified Rankin scale (mRS), and dichotomized as unfavorable (mRS 4-6, indicating severe disability or death) or favorable (mRS 0-3). Multivariable regression analyses were employed to identify EEG abnormalities associated with functional outcomes. RESULTS: Of the 364 patients enrolled in the SPICE study, 153 patients (49 ischemic strokes, 52 intracranial hemorrhages, and 52 subarachnoid hemorrhages) underwent at least one EEG at a median time of 4 (interquartile range 2-7) days post-stroke. Rates of diffuse slowing (70% vs. 63%, p = 0.37), focal slowing (38% vs. 32%, p = 0.15), periodic discharges (2.3% vs. 3.7%, p = 0.9), and electrographic seizures (4.5% vs. 3.7%, p = 0.4) were comparable between patients with unfavorable and favorable outcomes. Following adjustment for potential confounders, an unreactive EEG background to auditory and pain stimulations (OR 6.02, 95% CI 2.27-15.99) was independently associated with unfavorable outcomes. An unreactive EEG predicted unfavorable outcome with a specificity of 48% (95% CI 40-56), sensitivity of 79% (95% CI 72-85), and positive predictive value (PPV) of 74% (95% CI 67-81). Conversely, a benign EEG (defined as continuous and reactive background activity without seizure, periodic discharges, triphasic waves, or burst suppression) predicted favorable outcome with a specificity of 89% (95% CI 84-94), and a sensitivity of 37% (95% CI 30-45). CONCLUSION: The absence of EEG reactivity independently predicts unfavorable outcomes at one year in severe stroke patients requiring mechanical ventilation in the ICU, although its prognostic value remains limited. Conversely, a benign EEG pattern was associated with a favorable outcome.

OBJECTIVES: Psychological consequences of grief among relatives are insufficiently known. We reported incidence of prolonged grief among relatives of deceased patients with cancer. METHODS: Prospective cohort study of 611 relatives of 531 patients with cancer hospitalized for more than 72 hours and who died in 26 palliative care units was conducted. The primary outcome was prolonged grief in relatives 6 months after patient death, measured with the Inventory Complicated Grief (ICG > 25, range 0-76, a higher score indicates more severe symptoms) score. Secondary outcomes in relatives 6 months after patient death were anxiety and depression symptoms based on Hospital Anxiety and Depression Scale (HADS) score (range 0 [best]-42 [worst]), higher scores indicate more severe symptoms, minimally important difference 2.5. Post-traumatic stress disorder symptoms were defined by an Impact Event Scale-Revised score >22 (range 0-88, a higher score indicates more severe symptoms). RESULTS: Among 611 included relatives, 608 (99.5%) completed the trial. At 6 months, significant ICG scores were reported by 32.7% relatives (199/608, 95% CI, 29.0-36.4). The median (interquartile range ICG score) was 20.0 (11.5-29.0). The incidence of HADS symptoms was 87.5% (95% CI, 84.8-90.2%) at Days 3-5 and 68.7% (95% CI, 65.0-72.4) 6 months after patient's death, with a median (interquartile range) difference of -4 (-10 to 0) between these 2 time points. Improvement in HADS anxiety and depression scores were reported by 62.5% (362/579) relatives. SIGNIFICANCE OF RESULTS: These findings support the importance of screening relatives having risk factors of developing prolonged grief in the palliative unit and 6 months after patient's death.
RESUMO
BACKGROUND: The study aimed to describe the epidemiology and outcomes of hospital-acquired bloodstream infections (HABSIs) between COVID-19 and non-COVID-19 critically ill patients. METHODS: We used data from the Eurobact II study, a prospective observational multicontinental cohort study on HABSI treated in ICU. For the current analysis, we selected centers that included both COVID-19 and non-COVID-19 critically ill patients. We performed descriptive statistics between COVID-19 and non-COVID-19 in terms of patients' characteristics, source of infection and microorganism distribution. We studied the association between COVID-19 status and mortality using multivariable fragility Cox models. RESULTS: A total of 53 centers from 19 countries over the 5 continents were eligible. Overall, 829 patients (median age 65 years [IQR 55; 74]; male, n = 538 [64.9%]) were treated for a HABSI. Included patients comprised 252 (30.4%) COVID-19 and 577 (69.6%) non-COVID-19 patients. The time interval between hospital admission and HABSI was similar between both groups. Respiratory sources (40.1 vs. 26.0%, p < 0.0001) and primary HABSI (25.4% vs. 17.2%, p = 0.006) were more frequent in COVID-19 patients. COVID-19 patients had more often enterococcal (20.5% vs. 9%) and Acinetobacter spp. (18.8% vs. 13.6%) HABSIs. Bacteremic COVID-19 patients had an increased mortality hazard ratio (HR) versus non-COVID-19 patients (HR 1.91, 95% CI 1.49-2.45). CONCLUSIONS: We showed that the epidemiology of HABSI differed between COVID-19 and non-COVID-19 patients. Enterococcal HABSI predominated in COVID-19 patients. COVID-19 patients with HABSI had elevated risk of mortality. Trial registration ClinicalTrials.org number NCT03937245 . Registered 3 May 2019.

BACKGROUND: Data on SARS-CoV-2 load in lower respiratory tract (LRT) are scarce. Our objectives were to describe the viral shedding and the viral load in LRT and to determine their association with mortality in critically ill COVID-19 patients. METHODS: We conducted a binational study merging prospectively collected data from two COVID-19 reference centers in France and Switzerland. First, we described the viral shedding duration (i.e., time to negativity) in LRT samples. Second, we analyzed viral load in LRT samples. Third, we assessed the association between viral presence in LRT and mortality using mixed-effect logistic models for clustered data adjusting for the time between symptoms' onset and date of sampling. RESULTS: From March to May 2020, 267 LRT samples were performed in 90 patients from both centers. The median time to negativity was 29 (IQR 23; 34) days. Prolonged viral shedding was not associated with age, gender, cardiac comorbidities, diabetes, immunosuppression, corticosteroids use, or antiviral therapy. The LRT viral load tended to be higher in non-survivors. This difference was statistically significant after adjusting for the time interval between onset of symptoms and date of sampling (OR 3.78, 95% CI 1.13-12.64, p = 0.03). CONCLUSIONS: The viral shedding in LRT lasted almost 30 days in median in critically ill patients, and the viral load in the LRT was associated with the 6-week mortality.

BACKGROUND: Hospital-acquired bloodstream infections are common in the intensive care unit (ICU) and have a high mortality rate. Patients with cirrhosis are especially susceptible to infections, yet there is a knowledge gap in the epidemiological distinctions in hospital-acquired bloodstream infections between cirrhotic and non-cirrhotic patients in the ICU. It has been suggested that cirrhotic patients, present a trend towards more gram-positive infections, and especially enterococcal infections. This study aims to describe epidemiological differences in hospital-acquired bloodstream infections between cirrhotic and non-cirrhotic patients hospitalized in the ICU regarding infection sources, microorganisms and mortality. METHODS: Using prospective Eurobact-2 international cohort study data, we compared hospital-acquired bloodstream infections sources and microorganisms in cirrhotic and non-cirrhotic patients. The association between Enterococcus faecium and cirrhosis was studied using a multivariable mixed logistic regression. The association between cirrhosis and mortality was assessed by a multivariable frailty Cox model. RESULTS: Among the 1059 hospital-acquired bloodstream infections patients included from 101 centers, 160 had cirrhosis. Hospital-acquired bloodstream infection source in cirrhotic patients was primarily abdominal (35.6%), while it was pulmonary (18.9%) for non-cirrhotic (p < 0.01). Gram-positive hospital-acquired bloodstream infections accounted for 42.3% in cirrhotic patients compared to 33.2% in non-cirrhotic patients (p = 0.02). Hospital-acquired bloodstream infections in cirrhotic patients were most frequently caused by Klebsiella spp (16.5%), coagulase-negative Staphylococci (13.7%) and E. faecium (11.5%). E. faecium bacteremia was more frequent in cirrhotic patients (11.5% versus 4.5%, p < 0.01). After adjusting for possible confounding factors, cirrhosis was associated with higher E. faecium hospital-acquired bloodstream infections risk (Odds ratio 2.5, 95% CI 1.3-4.5, p < 0.01). Cirrhotic patients had increased mortality compared to non-cirrhotic patients (Hazard Ratio 1.3, 95% CI 1.01-1.7, p = 0.045). CONCLUSIONS: Critically ill cirrhotic patients with hospital-acquired bloodstream infections exhibit distinct epidemiology, with more Gram-positive infections and particularly Enterococcus faecium.
RESUMO
OBJECTIVES: Data on the impact of systemic antibiotics at the time of catheter insertion are scarce. Therefore, we assessed the association between concurrent antibiotic administration at insertion and short-term catheter-related infections. METHODS: We used individual data gathered from five large, randomized, controlled ICU trials. We analysed adult patients who required arterial, short-term central venous or dialysis catheter insertion in the ICU. The effect of antibiotics at insertion on major catheter-related infection (MCRI), catheter-related bloodstream infection (CRBSI) and colonization was estimated using multivariate marginal Cox and propensity score models. RESULTS: We included 10 269 patients and 18 743 catheters from 36 ICUs. Antibiotic use was ongoing at the time of 11 361 catheter insertions (60.6%). After adjusting for well-known risk factors for intravascular catheter infection, we observed a similar risk for MCRI (HR 0.83, 95%CI 0.62-1.10, p 0.19) and CRBSI (HR 0.85, 95%CI 0.60-1.22, p 0.38) between the antibiotic and no-antibiotic groups. A confirmatory analysis using propensity score showed consistent results. No specific antibiotic subclasses reduced the risk of MCRI. Non-fermenting Gram-negative bacilli were more frequently observed in the antibiotic group. CONCLUSIONS: Ongoing antibiotic administration at the time of catheter insertion was not associated with a decrease risk of catheter-related infections and should not be carried out for preventing such infections. Our results bring new insights to antimicrobial stewardship in critically ill patients and may direct empirical antimicrobial therapy if an intravascular catheter infection is suspected.

PURPOSE: Obesity increases the risk of nosocomial infection, but data regarding the role of body mass index (BMI) in catheter related infections are scarce. We used the data gathered from four randomized, controlled trials (RCTs) to investigate the association between body mass index (BMI) and intravascular catheter infections in critically ill obese patients. METHODS: Adult obese patients who required short-term central venous, arterial or dialysis catheter insertion in the intensive care unit (ICU) were analyzed. The association between BMI and major catheter-related infection (MCRI), catheter-related bloodstream infection (CRBSI) and catheter tip colonization was estimated using univariate and multivariate marginal Cox models. Exploratory analysis using dressing disruptions was added. RESULTS: A total of 2282 obese patients and 4275 catheters from 32 centers were included in this post-hoc analysis. Overall, 66 (1.5%) MCRI, 43 (1%) CRBSI and 399 (9.3%) catheter colonizations were identified. The hazard ratio (HR) for MCRI, CRBSI and colonization increased with BMI. After adjustment for well-known infection risk factors, the BMI ≥ 40 group had an increased risk for MCRI (HR 1.88, 95% CI 1.13-3.12, p = 0.015), CRBSI (HR 2.19, 95% CI 1.19-4.04, p = 0.012) and colonization (HR 1.44, 95% CI 1.12-1.84, p = 0.0038) compared to the BMI < 40 group. The mean dressing disruption per catheter was increased in the BMI ≥ 40 group (2.03 versus 1.68 in the BMI < 40 group, p = 0.05). CONCLUSIONS: Using the largest dataset ever collected from large multicentric RCTs, we showed that patients with BMI ≥ 40 had an increased risk for intravascular catheter infections. Targeted prevention measures should focus on this population with a particular attention to catheter care and dressing disruption.
