Purpose: Fever is frequent after extracorporeal membrane oxygenation (ECMO) decannulation. We aimed to evaluate the incidence of post-decannulation fever and describe its causes.

Methods: Adult ECMO patients who were successfully weaned from ECMO were retrospectively included.

Senescent cells within tumors and their stroma exert complex pro- and anti-tumorigenic functions. However, the identities and traits of these cells, and the potential for improving cancer therapy through their targeting, remain poorly characterized. Here, we identify a senescent subset within previously-defined cancer-associated fibroblasts (CAFs) in pancreatic ductal adenocarcinomas (PDAC) and in premalignant lesions in mice and humans.

Article Synopsis
  • High-risk pulmonary embolism (PE) patients can experience hemodynamic instability despite treatment; VA-ECMO is explored as a life-saving intervention, but pre-treatment with systemic thrombolysis poses risks of bleeding.
  • A study covering 72 patients assessed ECMO complications and survival rates, revealing similar 90-day survival rates and bleeding incidents between those treated with systemic thrombolysis and those without.
  • Long-term quality of life for survivors was found to be acceptable, indicating that recent systemic thrombolysis shouldn't be deemed a contraindication for VA-ECMO in high-risk PE cases.

Article Synopsis
  • Right ventricular failure (RVF) is a critical issue leading to high mortality rates shortly after heart transplantation, and the study explores how isoproterenol (Iso) can help improve heart function in these patients.
  • A retrospective study over one year evaluated the hemodynamic effects of Iso in 25 patients with early RVF, comparing no Iso treatment to low and high doses of Iso.
  • Results showed that Iso significantly increased heart rate and cardiac index, indicating improved heart function, while its effects on pulmonary pressures were minimal, highlighting its potential as a beneficial treatment for RVF post-heart transplant.

Introduction: Out-of-hospital cardiac arrest (OHCA) is a leading cause of mortality. Despite decades of intensive research and several technological advancements, survival rates remain low. The integration of extracorporeal cardiopulmonary resuscitation (ECPR) has been recognized as a promising approach in refractory OHCA.

  • The study investigates how VA-ECMO affects early renal recovery in patients with acute kidney injury (AKI) and cardiogenic shock, focusing on those who experienced AKI before ECMO treatment.
  • Out of 145 patients, 43% experienced early renal recovery within 7 days of starting VA-ECMO, while 57% did not.
  • Factors like use of nephrotoxic antibiotics, fluid balance, the severity of pre-ECMO AKI, and vasoactive-inotropic scores were identified as key indicators influencing the likelihood of early renal recovery.

Introduction: Delirium is a severe complication that is associated with short-term adverse events, prolonged hospital stay and neurological sequelae in survivors. Automated pupillometry is an easy-to-use device that allows for accurate objective assessment of the pupillary light responses in comatose patients in the intensive care unit (ICU). Whether automated pupillometry might predict delirium in critically ill patients is not known.

Background: Extracorporeal membrane oxygenation (ECMO) is an effective cardiorespiratory support technique in refractory cardiac arrest (CA). In patients under veno-arterial ECMO, the use of an Impella device, a microaxial pump inserted percutaneously, is a valuable strategy through a left ventricular unloading approach. ECMELLA, a combination of ECMO with Impella, seems to be a promising method to support end-organ perfusion while unloading the left ventricle.

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is an established rescue therapy in the management of refractory acute respiratory distress syndrome (ARDS). Although ECMO played an important role in previous respiratory viral epidemics, concerns about the benefits and usefulness of this technique were raised during the coronavirus disease 2019 (COVID-19) pandemic. Indeed, the mortality rate initially reported in small case series from China was concerning and exceeded 90%.

The SARS-CoV-2 pandemic has overwhelmed health care systems worldwide since its first wave. Intensive care units have been under a significant amount of pressure as patients with the most severe form of the disease presented with acute respiratory distress syndrome (ARDS). A proportion of them experienced refractory acute respiratory failure and had to be supported with veno-venous extracorporeal membrane oxygenation (VV-ECMO).

Background: Acute Kidney Injury (AKI) is a very frequent condition, occurring in about one in three patients admitted to an intensive care unit (ICU). AKI is a syndrome defined as a sudden decrease in glomerular filtration rate. However, this unified definition does not reflect the various mechanisms involved in AKI pathophysiology, each with its own characteristics and sensitivity to therapy.

Article Synopsis
  • The study investigates the outcomes of critically ill pregnant women with severe ARDS who underwent ECMO, focusing on whether the timing of delivery (before or after ECMO) affects maternal and fetal health.
  • Out of 563 women, those whose delivery was performed after ECMO faced higher rates of major bleeding, while fetal survival rates were significantly better when ECMO was started post-delivery.
  • Despite risks, overall maternal survival rates were high, and newborns showed no severe complications or long-term health issues, indicating the need for careful decision-making regarding delivery timing in these critical cases.

Introduction: Although viruses are an underestimated cause of community-acquired pneumonias (CAP) and hospital-acquired pneumonias (HAP)/ventilator-associated pneumonias (VAP) in intensive care unit (ICU) patients, they have an impact on morbidity and mortality.

Areas Covered: In this perspective article, we discuss the available data regarding the management of severe influenza CAP and herpesviridae HAP/VAP. We review diagnostic and therapeutic strategies in order to give clear messages and address unsolved questions.

Cellular senescence forms a barrier to tumorigenesis, by inducing cell cycle arrest in damaged and mutated cells. However, once formed, senescent cells often emit paracrine signals that can either promote or suppress tumorigenesis. There is evidence that, in addition to cancer cells, subsets of tumor stromal cells, including fibroblasts, endothelial cells, and immune cells, undergo senescence.

Pulmonary embolism (PE) is a common disease with an annual incidence rate ranging from 39-115 per 100,000 inhabitants. It is one of the leading causes of cardiovascular mortality in the USA and Europe. While the clinical presentation and severity may vary, it is a life-threatening condition in its most severe form, defined as high-risk or massive PE.

Background: Indeterminate randomized controlled trials (RCTs) in ARDS may arise from sample size misspecification, leading to abandonment of efficacious therapies.

Research Questions: If evidence exists for sample size misspecification in ARDS RCTs, has this led to rejection of potentially beneficial therapies? Does evidence exist for prognostic enrichment in RCTs using mortality as a primary outcome?

Study Design And Methods: We identified 150 ARDS RCTs commencing recruitment after the 1994 American European Consensus Conference ARDS definition and published before October 31, 2020. We examined predicted-observed sample size, predicted-observed control event rate (CER), predicted-observed average treatment effect (ATE), and the relationship between observed CER and observed ATE for RCTs with mortality and nonmortality primary outcome measures.

Introduction: Plasma free hemoglobin is the gold standard for monitoring hemolysis in extracorporeal membrane oxygenation (ECMO) but its routine use has some limitations. Carboxyhemoglobin (HbCO) is also a marker of intravascular hemolysis. We aimed to investigate HbCO as a marker of both hemolysis and oxygenator dysfunction in patients supported by ECMO.

Objectives: Sepsis is a common condition in the ICU. Despite much research, its prognosis remains poor. In 2017, a retrospective before/after study reported promising results using a combination of thiamine, ascorbic acid, and hydrocortisone called "metabolic resuscitation cocktail" and several randomized controlled trials assessing its effectiveness were performed.
