Sarcopenia in patients receiving TIPS is independently associated with increased risk of complications and mortality.

Background: Sarcopenia is an acknowledged risk factor for individuals with chronic liver disease, however, the influence on outcomes in patients receiving transjugular intrahepatic portosystemic shunt (TIPS) remains underexplored.

Aims: This study aimed to investigate the association between sarcopenia and incidence of complications and mortality post-TIPS.

Methods: A retrospective analysis was performed on 175 patients who underwent TIPS between 2011-2021 at a Belgian tertiary care center.

The Toulouse algorithm identifies patients with increased risk of cardiac decompensation only in patients with TIPS for refractory ascites.

Introduction And Objectives: TIPS placement is an effective, possibly life-saving, treatment for complications of portal hypertension. The pressure shift induced by the stent can lead to cardiac decompensation (CD). We investigated the incidence of CD, possible variables associated with CD and the validity of the Toulouse algorithm for risk prediction of CD post-TIPS.

Transcatheter arterial embolization for small-bowel bleeding: technical and clinical outcomes and risk factors for early recurrent bleeding.

Background: This study evaluated the technical and clinical outcomes of transcatheter arterial embolization (TAE) in patients with acute small-bowel bleeding (SBB) and aimed to identify potential risk factors for early recurrent bleeding after TAE.

Methods: Thirty-one patients with SBB managed with TAE between January 2006 and December 2021 were included. Technical and clinical success was defined as angiographic occlusion of the bleeding artery and disappearance of clinical or laboratory signs of persistent bleeding without major complications.

Evaluation of the QIAstat-Dx Respiratory SARS-CoV-2 Panel for detection of pathogens in nasopharyngeal and lower respiratory tract specimens.

This study evaluates the performance of the QIAstat-Dx Respiratory SARS-CoV-2 Panel (RS2P) for the detection of respiratory pathogens. RS2P testing was performed on 440 specimens, including 82 negatives and 358 specimens positive for 1 or more targets (520 targets initially detected). Initial testing was performed on multiple platforms during routine laboratory workflow.

Profiling Bacteria in the Lungs of Patients with Severe Influenza Versus COVID-19 with or without Aspergillosis.

The influence of the lung bacterial microbiome, including potential pathogens, in patients with influenza-associated pulmonary aspergillosis (IAPA) or coronavirus disease (COVID-19)-associated pulmonary aspergillosis (CAPA) has yet to be explored. To explore the composition of the lung bacterial microbiome and its association with viral and fungal infection, immunity, and outcome in severe influenza versus COVID-19 with or without aspergillosis. We performed a retrospective study in mechanically ventilated patients with influenza and COVID-19 with or without invasive aspergillosis in whom BAL for bacterial culture (with or without PCR) was obtained within 2 weeks after ICU admission.

Distinct immunometabolic signatures in circulating immune cells define disease outcome in acute-on-chronic liver failure.

Background And Aims: Acute-on-chronic liver failure (ACLF) is a complication of cirrhosis characterized by multiple organ failure and high short-term mortality. The pathophysiology of ACLF involves elevated systemic inflammation leading to organ failure, along with immune dysfunction that heightens susceptibility to bacterial infections. However, it is unclear how these aspects are associated with recovery and nonrecovery in ACLF.

Nutritional support in the cardiac intensive care unit.

Optimal care of critically ill patients in the cardiac intensive care unit includes adequate nutritional support. This review highlights the high prevalence of malnutrition in acute heart failure, acute coronary syndrome, cardiogenic shock, and post-cardiac arrest and its adverse impact on prognosis. There is a lack of robust evidence regarding appropriate nutritional support in this patient population.

Lower respiratory tract single-cell RNA sequencing and neutrophil extracellular trap profiling of COVID-19-associated pulmonary aspergillosis: a single centre, retrospective, observational study.

Background: COVID-19-associated pulmonary aspergillosis (CAPA) is a severe superinfection with the fungus Aspergillus affecting patients who are critically ill with COVID-19. The pathophysiology and the role of neutrophil extracellular traps (NETs) in this infection are largely unknown. We aimed to characterise the immune profile, with a focus on neutrophils and NET concentrations, of critically ill patients with COVID-19, with or without CAPA.

Tight Blood-Glucose Control without Early Parenteral Nutrition in the ICU.

Background: Randomized, controlled trials have shown both benefit and harm from tight blood-glucose control in patients in the intensive care unit (ICU). Variation in the use of early parenteral nutrition and in insulin-induced severe hypoglycemia might explain this inconsistency.

Methods: We randomly assigned patients, on ICU admission, to liberal glucose control (insulin initiated only when the blood-glucose level was >215 mg per deciliter [>11.

High Burden of COVID-19-Associated Pulmonary Aspergillosis in Severely Immunocompromised Patients Requiring Mechanical Ventilation.

Background: Coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) is a frequent superinfection in critically ill patients with COVID-19 and is associated with increased mortality rates. The increasing proportion of severely immunocompromised patients with COVID-19 who require mechanical ventilation warrants research into the incidence and impact of CAPA during the vaccination era.

Methods: We performed a retrospective, monocentric, observational study.

Factors influencing outcome of angiographic embolization for gastroduodenal hemorrhage related to peptic ulceration.

Purpose: Long-term outcome and prognostic factors of transcatheter embolization for gastroduodenal peptic ulcer bleeding are unknown. This study was conducted to evaluate the clinical outcome and factors associated with early recurrent bleeding and 30-day mortality of transcatheter arterial embolization (TAE) for severe, upper gastroduodenal hemorrhage associated with peptic ulcer and refractory to medical and endoscopic therapy.

Methods: A monocenter, retrospective study from 2005 to 2020 including 76 consecutive patients who underwent TAE as first-line therapy for bleeding gastroduodenal peptic ulcers refractory to endoscopic therapy.

A Pathology-based Case Series of Influenza- and COVID-19-associated Pulmonary Aspergillosis: The Proof Is in the Tissue.

Invasive pulmonary aspergillosis has emerged as a frequent coinfection in severe coronavirus disease (COVID-19), similarly to influenza, yet the clinical invasiveness is more debated. We investigated the invasive nature of pulmonary aspergillosis in histology specimens of influenza and COVID-19 ICU fatalities in a tertiary care center. In this monocentric, descriptive, retrospective case series, we included adult ICU patients with PCR-proven influenza/COVID-19 respiratory failure who underwent postmortem examination and/or tracheobronchial biopsy during ICU admission from September 2009 until June 2021.

Evaluation of the Aptima BV and CV/TV assays compared to conventional laboratory based testing methods for the diagnosis of vaginitis.

Purpose: Vaginitis is caused by bacterial vaginosis (BV), Candida vaginitis (CV) and Trichomonas vaginalis (TV). This retrospective study evaluates the performance of the Aptima CV/TV, and BV assays on the automated Panther system.

Methods: Two hundred forty-two multitest swabs were tested on the CV/TV assay and 422 on the BV assay.

Severe ARDS due to Ruxolitinib discontinuation syndrome: case presentation and literature review.

Objective: Discontinuation of Ruxolitinib (RUX), a JAK1/JAK2 inhibitor, can induce symptom-relapse and even life-threatening adverse events. Due to increasing use of RUX, this so-called RUX discontinuation syndrome (RDS) is becoming more prevalent. To create better awareness for this potentially fatal syndrome, we present a case of an adult male who developed a fatal RDS.

Do Cerebral Cortex Perfusion, Oxygen Delivery, and Oxygen Saturation Responses Measured by Near-Infrared Spectroscopy Differ Between Patients Who Fail or Succeed in a Spontaneous Breathing Trial? A Prospective Observational Study.

Background: Alterations in perfusion to the brain during the transition from mechanical ventilation (MV) to a spontaneous breathing trial (SBT) remain poorly understood. The aim of the study was to determine whether changes in cerebral cortex perfusion, oxygen delivery (DO), and oxygen saturation (%StiO) during the transition from MV to an SBT differ between patients who succeed or fail an SBT.

Methods: This was a single-center prospective observational study conducted in a 16-bed medical intensive care unit of the University Hospital Leuven, Belgium.

Impact of BMI on outcomes in respiratory ECMO: an ELSO registry study.

Purpose: The impact of body mass index (BMI) on outcomes in respiratory failure necessitating extracorporeal membrane oxygenation (ECMO) has been poorly described. We aimed to assess: (i) whether adults with class II obesity or more (BMI ≥ 35 kg/m) have worse outcomes than lean counterparts, (ii) the form of the relationship between BMI and outcomes, (iii) whether a cutoff marking futility can be identified.

Methods: A retrospective analysis of the Extracorporeal Life Support Organization (ELSO) Registry from 1/1/2010 to 31/12/2020 was conducted.

Atypical Hemolytic Uremic Syndrome Occurring After Receipt of mRNA-1273 COVID-19 Vaccine Booster: A Case Report.

Atypical hemolytic uremic syndrome (aHUS) is a subtype of thrombotic microangiopathy (TMA) characterized by a dysregulation of the alternative complement pathway. Here, we report a previously healthy 38-year-old woman in whom aHUS developed after a COVID-19 vaccine booster. One day after receipt of a booster dose of mRNA-1273 vaccine, she felt ill.

Modulation of thromboinflammation in hospitalized COVID-19 patients with aprotinin, low molecular weight heparin, and anakinra: The DAWn-Antico study.

Background: Thromboinflammation plays a central role in severe COVID-19. The kallikrein pathway activates both inflammatory pathways and contact-mediated coagulation. We investigated if modulation of the thromboinflammatory response improves outcomes in hospitalized COVID-19 patients.

Impact of tight blood glucose control within normal fasting ranges with insulin titration prescribed by the Leuven algorithm in adult critically ill patients: the TGC-fast randomized controlled trial.

Background: It remains controversial whether critical illness-related hyperglycemia should be treated or not, since randomized controlled trials (RCTs) have shown context-dependent outcome effects. Whereas pioneer RCTs found improved outcome by normalizing blood glucose in patients receiving early parenteral nutrition (PN), a multicenter RCT revealed increased mortality in patients not receiving early PN. Although withholding early PN has become the feeding standard, the multicenter RCT showing harm by tight glucose control in this context has been criticized for its potentially unreliable glucose control protocol.

Lung epithelial and myeloid innate immunity in influenza-associated or COVID-19-associated pulmonary aspergillosis: an observational study.

Background: Influenza-associated pulmonary aspergillosis (IAPA) and COVID-19-associated pulmonary aspergillosis (CAPA) affect about 15% of critically ill patients with influenza or COVID-19, respectively. These viral-fungal coinfections are difficult to diagnose and are associated with increased mortality, but data on their pathophysiology are scarce. We aimed to explore the role of lung epithelial and myeloid innate immunity in patients with IAPA or CAPA.
