Introduction: First-line oxygenation strategy in patients with acute hypoxaemic respiratory failure consists in standard oxygen or high-flow nasal oxygen therapy. Clinical practice guidelines suggest the use of high-flow nasal oxygen rather than standard oxygen. However, findings remain contradictory with a low level of certainty.

Article Synopsis
  • Endotracheal intubation (ETI) is crucial for critically ill patients
  • , but it has risks like hypoxemia; preoxygenation is used to enhance safety but can have unreliable monitoring through standard pulse oximeters (SpO2).
  • The Oxygen Reserve Index (ORI)
  • is proposed as a more reliable continuous measure during preoxygenation, targeting an ORI value of at least 0.6 over one minute instead of the standard SpO2 100% goal to improve outcomes.
  • A trial with 950 critically ill adults
  • will compare ORI monitoring against standard SpO2 monitoring during ETI; outcomes include the lowest SpO2 during intubation and cognitive

Background: Due to the low number of individuals with HIV-2, no randomised trials of HIV-2 treatment have ever been done. We hypothesised that a non-comparative study describing the outcomes of several antiretroviral therapy (ART) regimens in parallel groups would improve understanding of how differences between HIV-1 and HIV-2 might lead to different therapeutic approaches.

Methods: This pilot, phase 2, non-comparative, open-label, randomised controlled trial was done in Burkina Faso, Côte d'Ivoire, Senegal, and Togo.

In various applications, multiscale entropy (MSE) is often used as a feature to characterize the complexity of the signals in order to classify them. It consists of estimating the sample entropies (SEs) of the signal under study and its coarse-grained (CG) versions, where the CG process amounts to (1) filtering the signal with an average filter whose order is the scale and (2) decimating the filter output by a factor equal to the scale. In this paper, we propose to derive a new variant of the MSE.

Background: Recent studies identified coronavirus disease 2019 (COVID-19) as a risk factor for invasive pulmonary aspergillosis (IPA) but produced conflicting data on IPA incidence and impact on patient outcomes. We aimed to determine the incidence and outcomes of COVID-19-associated pulmonary aspergillosis (CAPA) in mechanically ventilated patients.

Methods: We performed a multicenter retrospective observational cohort study in consecutive adults admitted to 15 French intensive care units (ICUs) in 2020 for COVID-19 requiring mechanical ventilation.

  • International guidelines suggest keeping body temperature below 37.8 °C for unconscious patients after out-of-hospital cardiac arrest (OHCA), but targeting 33 °C may yield better results for patients with a nonshockable rhythm.
  • The study aimed to determine if inducing hypothermia at 33 °C leads to higher survival rates and better functional outcomes compared to maintaining normal body temperature (normothermia).
  • Data was gathered from two clinical trials involving unconscious OHCA patients with nonshockable rhythms, comparing those treated with hypothermia versus normothermia for a minimum of 24 hours, analyzing various factors influencing outcomes.*

  • Out-of-hospital cardiac arrest (OHCA) varies in cause and prognosis, prompting a study to assess the effectiveness of the Cardiac Arrest Prognosis (CAHP) Score compared to traditional methods (Utstein style criteria) for predicting patient outcomes.
  • The study collected data from 24 ICUs in France and Belgium on comatose patients with OHCA who had a stable return of spontaneous circulation, aiming to evaluate various predictive scores and their accuracy in anticipating neurological outcomes after 90 days.
  • Among the 658 patients analyzed, results showed a 63% mortality rate and noted that while Utstein criteria had moderate predictive capability (AUROC of 0.79), other scores demonstrated a range of performance, with some showing

  • Patients with severe COVID-19 in ICUs have a high risk of blood clots, prompting a study to compare the effects of intermediate-dose versus standard-dose anticoagulation.
  • The study included 1,174 patients and found no significant difference in 90-day mortality or ICU stay length between the two dosing groups, but intermediate-dose patients had fewer venous thrombo-embolism (VTE) incidents.
  • Both groups experienced similar rates of bleeding complications, indicating that while the doses impacted blood clot rates, they did not affect overall survival or safety.

Background And Objectives: To report the prevalence of acute encephalopathy and outcomes in patients with severe coronavirus disease 2019 (COVID-19) and to identify determinants of 90-day outcomes.

Methods: Data from adults with severe COVID-19 and acute encephalopathy were prospectively collected for patients requiring intensive care unit management in 31 university or university-affiliated intensive care units in 6 countries (France, United States, Colombia, Spain, Mexico, and Brazil) between March and September of 2020. Acute encephalopathy was defined, as recently recommended, as subsyndromal delirium or delirium or as a comatose state in case of severely decreased level of consciousness.

Nowadays, there is an increasing use of digital technologies and Artificial Intelligence (AI) such as Machine Learning (ML) models that leverage data to optimize the performances of systems in almost all activity sectors, including ML models for optimizing solutions related to CO2 capture from the atmosphere or CO2 emissions reduction from human activities. However, on the other hand, the use of AI models is leading to an increasing energy consumption that also raises environmental issues (in terms of CO2 emissions) which are less studied in the literature. This then raises the new question of a more realistic estimate of the carbon footprint (CO2 emissions in particular) of AI models in general, and particularly AI models aimed at reducing CO2 emissions.
