This prospective observational study aimed to explore the association between CAPA development and the incidence and prognosis of cytomegalovirus (CMV) reactivation in critically ill COVID-19 patients. Materials and Methods: We included all consecutive critically ill adult patients with confirmed COVID-19 infection who were admitted to three COVID-19 intensive care units (ICUs) in an Italian hospital from February 25, 2020, to May 8, 2022. A standardized procedure was employed for early detection of CAPA. Risk factors associated with CAPA and CMV reactivation and the association between CMV recurrence and mortality were estimated using adjusted Cox proportional hazard regression models. Results: CAPA occurred in 96 patients (16,6%) of the 579 patients analyzed. Among the CAPA population 40 (41,7%) patients developed CMV blood r...

This observational pre-post study included adult patients requiring invasive mechanical ventilation (IMV) for severe respiratory failure related to SARS-CoV-2 admitted in three COVID-19 intensive care units (ICUs) in an Italian hospital from 22 February 2020 to 8 March 2022. Selective digestive decontamination (SDD) was introduced from the end of April 2021 in the structured protocol for VAP prevention. The SDD consisted of a tobramycin sulfate, colistin sulfate, and amphotericin B suspension applied in the patient’s oropharynx and the stomach via a nasogastric tube. Three-hundred-and-forty-eight patients were included in the study. In the 86 patients (32.9%) who received SDD, the occurrence of VAP ...

This paper aims to describe a cases series of the inflammatory cytokine levels before and after hemadsorption during normothermic reperfusion in DCD donors of liver and kidneys. In this observational pilot paper, we describe 8 DCD donors of liver or kidneys in our center from the year 2018 to 2019. All DCD donor subjects had similar age, were younger than 60 years, without evident critical conditions, no liver or kidney dysfunction known, and they presented with poor neurological outcomes instrumentally and clinically documented. We observed in our patients an interesting reduction of IL-10 and TNF-α levels during the normothermic reperfusion with hemadsorption. We transplanted all livers and kidneys from DCD donors without significant compliances.

However, EEG interpretation requires the presence of an experienced neurophysiologist and is time-consuming. Aim of this study was to evaluate whether parameters derived from an automated pupillometer (AP) might help to assess the degree of cerebral dysfunction in critically ill patients.MethodsProspective study conducted in the Department of Intensive Care of Erasme University Hospital in Brussels, Belgium. Pupillary assessments were performed using the AP in three subgroups of patients, concomitantly monitored with continuous EEG: “anoxic brain injury”, “Non-anoxic brain injury” and “other diseases”. An independent neurologist blinded to patient's history and AP results scored the degree of encephalopathy and reactivity on EEG using a standardized scale. The mean value of Neurologic Pupil Index (NPi), pupillary size, constriction rate, constriction and dilation velocity (CV and DV) and la...

The purpose of the study was to compare the pupillary response and skin conductance to pain stimulation in critically ill unconscious patients. Methods: This observational study included adult patients admitted to the intensive care unit (ICU) with acute brain injury (Glasgow Coma Scale < 9 with a motor response < 5) and/or requirements for deep level of sedation. Automated pupillometry (Algiscan, ID-MED, Marseille, France) was used to determine pupillary reflex dilation during tetanic stimulation. The maximum intensity of the stimulation value allowed the determination of a pupillary pain index score ranging from 1 (no nociception) to 9 (high nociception): a pupillary pain index (PPI) score of ≤4 was used to reflect adequate pain control. For skin conductance (SC), the number of SC peaks per second (NSCF) was collected ...

Brain tissue oxygenation (PbtO2) can be measured as a part of a neurological multimodal neuromonitoring Low PbtO2 has been associated with poor neurologic recovery. There is scarce data on the impact of PbtO2 guided-therapy on patients’ outcome. Methods This single-center cohort study (June 2014-March 2020) included all patients admitted to the ICU after SAH who required multimodal monitoring. Patients with imminent brain death were excluded. Our primary goal was to assess the impact of PbtO2-guided therapy on neurological outcome. Secondary outcome included the association of brain hypoxia with outcome. Results Of the 163 patients that underwent ICP monitoring, 62 were monitored with PbtO2 and 54 (87%) had at least one episode of brain hypoxia. In patients that required treatment based on neuromonitoring strategies, PbtO2-guided therapy ...

Methods: Retrospective analysis of patients admitted to our hospital with suspicion of COVID-19. Demographic, clinical and laboratory data were collected on admission. Eosinopenia was defined as eosinophils < 100 cells/mm3. The outcomes of this study were the association between eosinophils count on admission and positive real-time reverse transcription polymerase chain reaction (rRT-PCR) test and with suggestive chest computerized tomography (CT) of COVID-19 pneumonia. Results: A total of 174 patients was studied. Of those, 54% had positive rRT-PCR for SARS-CoV-2. A chest CT-scan was performed in 145 patients; 71% showed suggestive findings of COVID-19. Eosinophils on admission had a high predictive accuracy for positive rRT-PCR and suggestive chest CT-scan (area under the receiver operating characteristic—ROC curve, 0.84 (95% CIs 0.78–0.90) and 0.84 (95% CIs 0.77–0.91)...

METHODS In this retrospective study, we enrolled adult cirrhotic patients admitted to the Intensive Care Unit undergoing automated pupillometry assessment within the first 72 h since ICU admission. Encephalopathy was assessed with West-Haven classification and Glasgow Coma Scale. Pupillometry-derived variables were also correlated with biological variables, including ammonium, renal function or inflammatory parameters, measured on the day of pupillary assessment. RESULTS A total of 62 critically ill cirrhotic patients (Age 61 [52-68] years; 69% male) were included. Median GCS and West-Haven classification were 14 [11-15] and 1 [0-3], respectively. There was a significant although weak correlation between GCS and constriction velocity (CV; R2 = 0.1; p = 0.017). We observed significant differences in CV and DV values among different levels of West-Haven classification. When only patients with encephalopathy (n = 42) or severe HE (n = 18) were considered, a weak correlation between GCS and worst CV was observed. When patients receiving sedatives or opioids were excluded, no significant correlation between pupillometry and clinical variables was observed. CONCLUSIONS Pupillary function assessed by the automated pupillometry was poorly associated with encephalopathy scales in cirrhotic patients.

We aimed to assess the prognostic role of serial blood lactate measurements on hospital mortality and neurological outcomes at 3 months after SAH. We reviewed all SAH patients admitted to the intensive care unit from 2007 to 2019 and recorded the highest daily arterial lactate concentration for the first 6 days. Patients with no lactate concentration were excluded. Hyperlactatemia was defined as a blood lactate concentration >2.0 mmol/L. A total of 456 patients were included: 158 (35%) patients died in hospital and 209 (46%) had an unfavorable outcome (UO) at 3 months. The median highest lactate concentration was 2.7 (1.8–3.9) mmol/L. Non-survivors and patients with UO had significantly higher lactate concentrations compared to other patients. Hyperlactatemia increased the chance of ...

Design: Retrospective analysis of prospectively collected data on coronavirus disease 2019 patients, included between March 10, and April 30, 2020. Setting: ICU of an University Hospital in Belgium. Patients and Interventions: Critically ill adult mechanically ventilated coronavirus disease 2019 patients were eligible if they underwent a CT pulmonary angiography, as part of the routine management in case of persistent hypoxemia or respiratory deterioration. The primary endpoint of this study was the occurrence of pulmonary embolism according to the use of standard thromboprophylaxis (i.e. subcutaneous enoxaparin 4,000 international units once daily) or high regimen thromboprophylaxis (i.e. subcutaneous enoxaparin 4,000 international units bid or therapeutic unfractioned heparin). Measurements and Main Results: Of 49 mechanically ventilated coron...

Main characteristics and behaviours were compared to gain insights into the NEET condition in Italy. The sample included 111 NEETs (males = 73) and 117 EETs (males = 106) aged 16 to 23 years, belonging to comparable socio-demographic backgrounds. A self-report questionnaire was prepared to gain general information and investigate psychological well-being and behaviours. Most of the sample reported good relationships with parents. Education level and addictive behaviours were significantly different between NEETs and EETs while psychological well-being was not significantly different in relation to thoughts of suicide, unpleasant thoughts, weakness in the morning and nervousness. The heterogeneity of NEETs and the role of socio-cultural background in their psychophysical discomfort were highlighted. However, differently from reported in the literature, NEET adolescents sampled in this study, particularly those without social or family problems, did not show higher percentages of health or psychological problems when compared to their peer EETs. Furthermore, NEETs did not focus on the problem of their status, which also reflects a vague idea of the future.

High Interleukin-6 (IL-6) levels in COVID-19 patients suggest that a cytokine storm may play a major role in the pathophysiology and are considered as a relevant parameter in predicting most severe course of disease. The aim of this study was to assess repeated IL-6 levels in critically ill COVID-19 patients admitted to our Intensive Care Unit (ICU) and to evaluate their relationship with patient’s severity and outcome. Methods We conducted a retrospective study on patients admitted to the ICU with a diagnosis of COVID-19 between March 10 (i.e. the date of the first admitted patients) and April 30, 2020. Demographic, clinical and laboratory data were collected at admission. On the day of IL-6 blood concentration measurement, we also collected results of D-Dimers, C-Reactive Protein, white blood cells and lymphocytes count, lactate dehydrogenase (LDH) and ferritin as w...
