Mucosal administration of anti-bacterial antibodies provide long-term cross-protection against Pseudomonas aeruginosa respiratory infection.

Bacterial respiratory infections, either acute or chronic, are major threats to human health. Direct mucosal administration, through the airways, of therapeutic antibodies (Abs) offers a tremendous opportunity to benefit patients with respiratory infections. The mode of action of anti-infective Abs relies on pathogen neutralization and crystallizable fragment (Fc)-mediated recruitment of immune effectors to facilitate their elimination.

Critically ill severe hypothyroidism: a retrospective multicenter cohort study.

Background: Severe hypothyroidism (SH) is a rare but life-threatening endocrine emergency. Only a few data are available on its management and outcomes of the most severe forms requiring ICU admission. We aimed to describe the clinical manifestations, management, and in-ICU and 6-month survival rates of these patients.

Awake prone positioning for patients with COVID-19-induced acute hypoxemic respiratory failure.

Whereas prone positioning of intubated patients suffering from acute respiratory distress syndrome represents the standard of care, proning non-intubated patients, so-called "awake prone positioning (APP)," has only recently gained popularity and undergone scientific evaluation. In this review, we summarize current evidence on physiological and clinical effects of APP on patients' centered outcomes, such as intubation and mortality, the safety of the technique, factors and predictors of success, practical issues for optimal implementation, and future areas of research. Current evidence supports using APP among patients suffering from acute hypoxemic respiratory failure due to COVID-19 and undergoing advanced respiratory support, such as high-flow nasal cannula, in an intensive care unit setting.

Poly-L-Lysine to Fight Antibiotic Resistances of .

is a major hospital-associated pathogen that can cause severe infections, most notably in patients with cystic fibrosis (CF) or those hospitalized in intensive care units. Given its remarkable ability to resist antibiotics, eradication has grown more challenging. Therefore, there is an urgent need to discover and develop new strategies that can counteract -resistant strains.

Continued enteral nutrition until extubation compared with fasting before extubation in patients in the intensive care unit: an open-label, cluster-randomised, parallel-group, non-inferiority trial.

Background: Fasting is frequently imposed before extubation in patients in intensive care units, with the aim to reduce risk of aspiration. This unevaluated practice might delay extubation, increase workload, and reduce caloric intake. We aimed to compare continued enteral nutrition until extubation with fasting before extubation in patients in the intensive care unit.

Oral supplementation with yeast -glucans improves the resolution of -associated inflammatory responses independently of monocyte/macrophage immune training.

Introduction: Confronted with the emerging threat of antimicrobial resistance, the development of alternative strategies to limit the use of antibiotics or potentiate their effect through synergy with the immune system is urgently needed. Many natural or synthetic biological response modifiers have been investigated in this context. Among them, β-glucans, a type of soluble or insoluble polysaccharide composed of a linear or branched string of glucose molecules produced by various cereals, bacteria, algae, and inferior (yeast) and superior fungi (mushrooms) have garnered interest in the scientific community, with not less than 10,000 publications over the last two decades.

Prone positioning of nonintubated patients with acute hypoxemic respiratory failure.

Purpose Of Review: Since the early pandemic, prone positioning has been broadly utilized for nonintubated patients (so-called 'awake prone positioning, APP') with coronavirus disease 2019 (COVID-19) induced acute hypoxemic respiratory failure (AHRF).

Recent Findings: Numerous clinical studies have been conducted to investigate the effects of APP on oxygenation, intubation, and mortality. However, several questions remain unclear, such as the patient populations who benefit most from APP, the best length of daily duration on APP, how to improve adherence to APP, and the mechanisms of APP efficacy.

[Sotorasib treatment in KRAS G12C-mutated non-small cell lung cancer: Experience in the Tours university hospital].

Following the CodeBreak 100 study, since 2021 sotorasib has been available in France, with authorization for early access in treatment of non-small cell lung cancer with a KRAS G12C mutation. Our retrospective observational study was designed to determine the efficacy and safety of sotorasib under real-life conditions in patients treated at the Tours CHRU. Our study of 15 patients showed sotorasib to be effective in 47% of cases, with overall survival of 4 months and median progression-free survival of 5.

CD1 and MR1: An update after a long-awaited reunion.

CD1 molecules and the MHC-related protein 1 (MR1) present lipid and small molecule antigens, respectively, for T cell surveillance. The biology of these molecules, the antigens they present, and the T cells that respond to them were recently discussed during the 12 International CD1-MR1 Meeting held in Gothenburg, Sweden.

1-year mortality in lung cancer in France according to key timepoints of care pathways.

Background: It is unclear whether delays in care affect prognosis of patients with lung cancer. The primary objective of this study was to describe the care pathway of patients diagnosed with lung cancer in a French region. Secondary objectives were to identify markers associated with 1) time from imaging to treatment and 2) with 1-year survival.

Inhaled IgG1 antibodies: The buffering system is an important driver of stability during mesh-nebulization.

In the past decade, oral inhalation has been a thriving focus of research to administer antibody directly to the lungs as an aerosol, for local treatment of respiratory diseases. Formulation of inhaled antibodies is central for the stability of antibody, lung safety and to ensure inhaler performances. Surfactants have already been shown to prevent antibody degradation during aerosolization, but little is known about the impact of other components of liquid formulations on the structural stability of antibodies.

Spontaneous-Breathing Trials with Pressure-Support Ventilation or a T-Piece.

Background: Spontaneous-breathing trials can be performed with the use of either pressure-support ventilation (PSV) or a T-piece. Whether PSV trials may result in a shorter time to tracheal extubation than T-piece trials, without resulting in a higher risk of reintubation, among patients who have a high risk of extubation failure is unknown.

Methods: In this multicenter, open-label trial, we randomly assigned patients who had a high risk of extubation failure (i.

Different epidemiology of bloodstream infections in COVID-19 compared to non-COVID-19 critically ill patients: a descriptive analysis of the Eurobact II study.

Background: The study aimed to describe the epidemiology and outcomes of hospital-acquired bloodstream infections (HABSIs) between COVID-19 and non-COVID-19 critically ill patients.

Methods: We used data from the Eurobact II study, a prospective observational multicontinental cohort study on HABSI treated in ICU. For the current analysis, we selected centers that included both COVID-19 and non-COVID-19 critically ill patients.

Outcomes of mild-to-moderate postresuscitation shock after non-shockable cardiac arrest and association with temperature management: a post hoc analysis of HYPERION trial data.

Background: Outcomes of postresuscitation shock after cardiac arrest can be affected by targeted temperature management (TTM). A post hoc analysis of the "TTM1 trial" suggested higher mortality with hypothermia at 33 °C. We performed a post hoc analysis of HYPERION trial data to assess potential associations linking postresuscitation shock after non-shockable cardiac arrest to hypothermia at 33 °C on favourable functional outcome.

Assessing oral comprehension with an eye tracking based innovative device in critically ill patients and healthy volunteers: a cohort study.

Purpose: Communication of caregivers and relatives to patients is a major difficulty in intensive care units (ICU). Patient's comprehension capabilities are variable over time and traditional comprehension tests cannot be implemented. Our purpose was to evaluate an oral comprehension test adapted for its automatic implementation using eye-tracking technology among ICU patients.

Alternative Routes of Administration for Therapeutic Antibodies-State of the Art.

Background: For the past two decades, there has been a huge expansion in the development of therapeutic antibodies, with 6 to 10 novel entities approved each year. Around 70% of these Abs are delivered through IV injection, a mode of administration allowing rapid and systemic delivery of the drug. However, according to the evidence presented in the literature, beyond the reduction of invasiveness, a better efficacy can be achieved with local delivery.
