Coronary angiography after cardiac arrest: Rationale and design of the COACT trial.

BACKGROUND: Ischemic heart disease is a major cause of out-of-hospital cardiac arrest. The role of immediate coronary angiography (CAG) and percutaneous coronary intervention (PCI) after restoration of spontaneous circulation following cardiac arrest in the absence of ST-segment elevation myocardial infarction (STEMI) remains debated. HYPOTHESIS: We hypothesize that immediate CAG and PCI, if indicated, will improve 90-day survival in post-cardiac arrest patients without signs of STEMI. DESIGN: In a prospective, multicenter, randomized controlled clinical trial, 552 post-cardiac arrest patients with restoration of spontaneous circulation and without signs of STEMI will be randomized in a 1:1 fashion to immediate CAG and PCI (within 2 hours) versus initial deferral with CAG and PCI after neurological recovery. The primary end point of the study is 90-day survival. The secondary end points will include 90-day survival with good cerebral performance or minor/moderate disability, myocardial injury, duration of inotropic support, occurrence of acute kidney injury, need for renal replacement therapy, time to targeted temperature control, neurological status at intensive care unit discharge, markers of shock, recurrence of ventricular tachycardia, duration of mechanical ventilation, and reasons for discontinuation of treatment. SUMMARY: The COACT trial is a multicenter, randomized, controlled clinical study that will evaluate the effect of an immediate invasive coronary strategy in post-cardiac arrest patients without STEMI on 90-day survival.

The impact of high versus standard enteral protein provision on functional recovery following intensive care admission (PRECISE trial): study protocol for a randomized controlled, quadruple blinded, multicenter, parallel group trial in mechanically ventilated patients.

BACKGROUND: Critically ill patients are subject to severe skeletal muscle wasting during intensive care unit (ICU) stay, resulting in impaired short- and long-term functional outcomes and health-related quality of life. Increased protein provision may improve functional outcomes in ICU patients by attenuating skeletal muscle breakdown. Supporting evidence is limited however and results in great variety in recommended protein targets. METHODS: The PRECISe trial is an investigator-initiated, bi-national, multi-center, quadruple-blinded randomized controlled trial with a parallel group design. In 935 patients, we will compare provision of isocaloric enteral nutrition with either a standard or high protein content, providing 1.3 or 2.0 g of protein/kg/day, respectively, when fed on target. All unplanned ICU admissions with initiation of invasive mechanical ventilation within 24 h of admission and an expected stay on ventilator support of at least 3 days are eligible. The study is designed to assess the effect of the intervention on functional recovery at 1, 3, and 6 months following ICU admission, including health-related quality of life, measures of muscle strength, physical function, and mental health. The primary endpoint of the trial is health-related quality of life as measured by the Euro-QoL-5D-5-level questionnaire Health Utility Score. Overall between-group differences will be assessed over the three time points using linear mixed-effects models. DISCUSSION: The PRECISe trial will evaluate the effect of protein on functional recovery including both patient-centered and muscle-related outcomes. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04633421 . Registered on November 18, 2020. First patient in (FPI) on November 19, 2020. Expected last patient last visit (LPLV) in October 2023.

Cost Analysis From a Randomized Comparison of Immediate Versus Delayed Angiography After Cardiac Arrest.

Background In patients with out-of-hospital cardiac arrest without ST-segment elevation, immediate coronary angiography did not improve clinical outcomes when compared with delayed angiography in the COACT (Coronary Angiography After Cardiac Arrest) trial. Whether 1 of the 2 strategies has benefits in terms of health care resource use and costs is currently unknown. We assess the health care resource use and costs in patients with out-of-hospital cardiac arrest. Methods and Results A total of 538 patients were randomly assigned to a strategy of either immediate or delayed coronary angiography. Detailed health care resource use and cost-prices were collected from the initial hospital episode. A generalized linear model and a gamma distribution were performed. Generic quality of life was measured with the RAND-36 and collected at 12-month follow-up. Overall total mean costs were similar between both groups (EUR 33 575±19 612 versus EUR 33 880±21 044; P=0.86). Generalized linear model: (ß, 0.991; 95% CI, 0.894-1.099; P=0.86). Mean procedural costs (coronary angiography and percutaneous coronary intervention, coronary artery bypass graft) were higher in the immediate angiography group (EUR 4384±3447 versus EUR 3028±4220; P<0.001). Costs concerning intensive care unit and ward stay did not show any significant difference. The RAND-36 questionnaire did not differ between both groups. Conclusions The mean total costs between patients with out-of-hospital cardiac arrest randomly assigned to an immediate angiography or a delayed invasive strategy were similar during the initial hospital stay. With respect to the higher invasive procedure costs in the immediate group, a strategy awaiting neurological recovery followed by coronary angiography and planned revascularization may be considered.

Should we abandon corticosteroids during septic shock? No.

PURPOSE OF REVIEW: With the publication of the results of the recent CORTICUS trial, stress ('low') doses of corticosteroids for the treatment of vasopressor-dependent septic shock in adults can still be considered controversial. The purpose of this narrative review is to elaborate the pros and cons of this treatment in clinical practice and to formulate clinical and research directions. RECENT FINDINGS: The recent CORTICUS study only shows a beneficial effect of stress doses of corticosteroids in the time interval to shock reversal and not on mortality, potentially explained by an increased risk for superinfection. The mortality in the placebo arm was relatively low and lower than in earlier randomized studies in which stress doses of corticosteroids had a favorable hemodynamic effect and conferred a survival benefit in septic shock. SUMMARY: Treatment by stress doses of corticosteroids should not be abandoned during septic shock. Additional studies are needed, however, to better delineate the patient group with the highest likelihood to benefit from this therapy, as a function of severity of illness, response to adrenocorticotrophic hormone testing or both. For now, results of the CORTICUS study should not change current clinical practice of administering 200-300 mg of hydrocortisone daily (in divided doses) in case of fluid and vasopressor-insensitive septic shock and rapid tapering of this treatment on the basis of a hemodynamic response.

Impact of single room design on the spread of multi-drug resistant bacteria in an intensive care unit.

BACKGROUND: Cross-transmission of nosocomial pathogens occurs frequently in intensive care units (ICU). The aim of this study was to investigate whether the introduction of a single room policy resulted in a decrease in transmission of multidrug-resistant (MDR) bacteria in an ICU. METHODS: We performed a retrospective study covering two periods: between January 2002 and April 2009 (old-ICU) and between May 2009 and March 2013 (new-ICU, single-room). These periods were compared with respect to the occurrence of representative MDR Gram-negative bacteria. Routine microbiological screening, was performed on all patients on admission to the ICU and then twice a week. Multi-drug resistance was defined according to a national guideline. The first isolates per patient that met the MDR-criteria, detected during the ICU admission were included in the analysis. To investigate the clonality, isolates were genotyped by DiversiLab (bioMérieux, France) or Amplified Fragment Length Polymorphism (AFLP). To guarantee the comparability of the two periods, the 'before' and 'after' periods were chosen such that they were approximately identical with respect to the following factors: number of admissions, number of beds, bed occupancy rate, per year and month. RESULTS: Despite infection prevention efforts, high prevalence of MRD bacteria continue to occur in the original facility. A marked and sustained decrease in the prevalence of MDR-GN bacteria was observed after the migration to the new ICU, while there appear to be no significant changes in the other variables including bed occupancy and numbers of patient admissions. CONCLUSION: Single room ICU design contributes significantly to the reduction of cross transmission of MRD-bacteria.

Pulmonary leucostasis syndrome presented by unilateral pulmonary infiltrates.

A 48-year-old woman presented with suspected acute myelogenous leukaemia with a leucocyte count of 80×10(9)/L. On admission, she had high fever and shortness of breath. Chest X-ray demonstrated unilateral consolidations of right lung suggestive for pneumonia and broad spectrum antibiotics were started. Her condition rapidly deteriorated and despite the clinical diagnosis of pulmonary leucostasis and treatment with leucapheresis the patient died within 2 days after admission from progressive respiratory failure and multiorgan failure. Autopsy showed diffuse leucostasis in the pulmonary capillaries. The present case illustrates that pulmonary leucostasis may be presented by unilateral chest X-ray abnormalities and without clear neurological symptoms (headache and blurred vision). Clinicians should be aware of this since delayed treatment may increase mortality.
