Background: Cardiac surgery can lead to dysregulation with a pro-inflammatory state, resulting in adverse outcomes. Hemadsorption using the AN69 membrane (Oxiris membrane) has the properties to chelate inflammatory cytokines. We hypothesized that in patients at high risk of inflammation, the use of the Oxiris membrane could decrease inflammation, preserve endothelial function, and improve postoperative outcomes.

Article Synopsis
  • Intestinal ischemia-reperfusion injury can lead to both large-scale (macrocirculatory) and small-scale (microcirculatory) blood flow failures, and the study aimed to test if combining a vasoconstrictor (norepinephrine) with a vasodilator (ilomedin) improves blood pressure and circulation after injury.
  • The research was conducted on 21 pigs, with three groups receiving different treatments before and after a 2-hour induced small bowel ischemia followed by reperfusion, measuring various circulatory parameters and biomarkers.
  • Results showed no significant differences in mean arterial pressure or cardiac index between the groups, but the combination therapy group had notably better microcirculation performance immediately after and two

Background: Invasive candidiasis/candidemia (IC/C) is associated with a substantial health economic burden driven primarily by prolonged hospital stay. The once-weekly IV echinocandin, rezafungin acetate, has demonstrated non-inferiority to caspofungin in the treatment of IC/C. This paper reports a post hoc pooled exploratory analysis of length of stay (LoS) for hospital and intensive care unit (ICU) stays in two previously published clinical trials (ReSTORE [NCT03667690] and STRIVE [NCT02734862], that compared rezafungin with daily IV caspofungin (stable patients in the caspofungin group who met relevant criteria could step down to fluconazole after 3 days or more).

Article Synopsis
  • Non-steroidal anti-inflammatory drugs (NSAIDs) are often used for managing acute postoperative pain after surgery, but their use in cardiac procedures raises concerns about risks like increased bleeding and kidney injury.
  • The KETOPAIN trial aims to evaluate the effectiveness and safety of ketoprofen in treating postoperative pain in cardiac surgery patients, involving 238 participants randomized to receive either ketoprofen or a placebo after the procedure.
  • The study will assess various outcomes, including pain intensity at 24 hours post-surgery, opioid consumption, complications, and quality of life up to three months afterward.

Article Synopsis
  • Rezafungin, a new once-weekly echinocandin, showed similar effectiveness to caspofungin in treating candidemia and invasive candidiasis in the ReSTORE trial, particularly in terms of day 30 all-cause mortality and day 14 global cure rates.
  • The study involved patients aged 18 and older, comparing the outcomes of those receiving rezafungin to those on caspofungin, with specific focus on patients who had a positive culture close to the time of treatment randomization.
  • Results indicated comparable safety and efficacy between the two treatments, with rezafungin showing potential advantages in early mycological response, suggesting it could be an effective option for treatment.

Background: Postoperative complications, particularly respiratory complications, are of significant clinical concern in patients undergoing elective thoracic surgery. Dexamethasone (DXM), commonly administered to prevent postoperative nausea and vomiting (PONV), has potential anti-inflammatory effects that might be beneficial in reducing these complications. We aimed to investigate whether intraoperative DXM administration could mitigate the occurrence of respiratory complications following elective thoracic surgery.

Background: Post-induction anaesthesia often promotes intraoperative hypotension (IOH) that can worsen postoperative outcomes. This study aims to assess the benefit of norepinephrine versus ephedrine at the induction of anaesthesia to prevent postoperative complications following major abdominal surgery by preventing IOH.

Methods And Analysis: The EPON STUDY is a prospective single-centre randomised controlled trial with the planned inclusion of 500 patients scheduled for major abdominal surgery at the Amiens University Hospital.

Objectives: Serratus anterior plane block (SAPB) and paravertebral block (PVB) are well known to reduce pain levels after video-assisted thoracoscopic surgery (VATS). However, the relative efficacies of each block and a combination of the 2 have not been fully characterized. The objective of the present study was to assess the efficacy of PVB alone, SAPB alone and the combination of PVB and SAPB with regard to the occurrence and intensity of pain after VATS.

Purpose: The present study aimed at assessing the prevalences of post-traumatic stress disorder (PTSD) (main objective), anxiety, depression, and burnout syndrome (BOS) and their associated factors in intensive care unit (ICU) staff workers in the second year of the COVID-19 pandemic.

Materials And Methods: An international cross-sectional multicenter ICU-based online survey was carried out among the ICU staff workers in 20 ICUs across 3 continents. ICUs staff workers (both caregivers and non-caregivers) were invited to complete PCL-5, HADS, and MBI questionnaires for assessing PTSD, anxiety, depression, and the different components of BOS, respectively.

Background: Right ventricle dilatation (RVD) is a common complication of non-intubated COVID-19 pneumonia caused by pro-thrombotic pneumonitis, intra-pulmonary shunting, and pulmonary vascular dysfunction. In several pulmonary diseases, RVD is routinely measured on computed tomography pulmonary angiogram (CTPA) by the right ventricle-to-left ventricle (LV) diameter ratio > 1 for predicting adverse events.

Objective: The aim of the study was to evaluate the association between RVD and the occurrence of adverse events in a cohort of critically ill non-intubated COVID-19 patients.

Clinical presentation and mortality of patients treated with extracorporeal membrane oxygenation (ECMO) for COVID-19 acute respiratory distress syndrome (CARDS) were different during the French epidemic waves. The management of COVID-19 patients evolved through waves as much as knowledge on that new viral disease progressed. We aimed to compare the mortality rate through the first three waves of CARDS patients on ECMO and identify associated risk factors.
