Optimal dosage regimens of cefiderocol administered by short, prolonged or continuous infusion: a PK/PD simulation study.

Background And Objectives: Cefiderocol approved dosages are based on a prolonged infusion (PI) of 3 h that may not be adequate in all settings The objective of this study was to identify alternative cefiderocol dosage regimens based on short infusion (SI) or continuous infusion (CI).

Methods: We performed 1000-patient pharmacokinetic/pharmacodynamic (PK/PD) simulations based on a reference population model. Drug penetration into the epithelial lining fluid (ELF) was considered for pneumonia.

Factors influencing the turnover of nurses in French intensive care unit - A multicenter interview survey.

Background: Nurse retention is a major concern in healthcare settings, especially among intensive care units (ICU), in which nurses are highly specialized. The objective was to describe the nurse courses after their entrance into the ICU, their motivation for leaving the ICU, and to identify the independent factors that influenced the nurse resignation from their units.

Methods: In 3 different centers, every ICU nurse working between 2013 and 2023 was telephonically contacted and was asked to describe their career and, when appropriate, the reasons that influenced their resignation from their units; they rated on a Likert scale of 14 factors that influenced their decision.

Mycotic aneurysm due to Magnusiomyces capitatus complicating a second liver transplant in a colonized patient.

This report presents an extremely rare case of fungal mycotic aneurysm due to Magnusiomyces capitatus in a 51-year-old immunocompromised woman. The diagnosis was based on multiple CT-scans and various samples positive for the pathogen identified by sequencing of the Internal Transcribed Spacer region. Long-term treatment using caspofungin for previous candidemia would have promoted the dissemination of this intrinsically echinocandin-resistant fungus, from colonization sites in the lung and rectal areas.

The Acute Ingestion of Yerba Mate (Ilex paraguariensis) Infusion Does Not Modify Endothelial Function, Hemodynamics, or Heart Rate Variability: A Randomized Crossover Clinical Trial.

Background And Aims: Herbal plants may contribute to reducing the incidence of cardiovascular disease. Yerba mate (YM) emerges as a candidate to improve endothelial function, hemodynamics, and heart rate variability (HRV) due to its antioxidant and anti-inflammatory properties, potentially decreasing cardiovascular risk. Therefore, studies are needed to assess the effect of YM ingestion on these parameters.

Perioperative methadone compared to placebo in elderly hip fracture patients: a study protocol for a randomized controlled trial (MetaHip trial).

Background: Hip fractures are a source of severe pain among the elderly population and pose challenges due to limited analgesic tolerance. Perioperative methadone has shown promise in our pilot study suggesting a safe dose of 0.10 mg/kg, prompting further investigation into its benefits for elderly hip fracture patients.

Human Endogenous Retroviruses Expression in Autoimmunity.

In relation to ancient infections, a substantial number of retroviral sequences with persistent immunogenic potential were integrated within the human genome (HERVs). Under physiological conditions, coding sequences from HERVs can participate in cell/tissue homeostasis and physiological functions in an epigenetically controlled manner. However, HERV expression is susceptible to contribute to various pathologies, including autoinflammatory and autoimmune disorders, when reprogrammed by exogenous stimuli such as drugs or microbial infections.

Changes in Respiratory Syncytial Virus-Associated Hospitalisations Epidemiology After Nirsevimab Introduction in Lyon, France.

Background: Respiratory Syncytial Virus (RSV) is a major health concern, particularly for infants. In France, Nirsevimab, a long-acting monoclonal antibody to prevent RSV-associated lower respiratory tract infections (LRTI) was available from September 2023. We described RSV-associated LRTI hospitalisations during the 2023-2024 season among infants younger than six months born at the Hospices Civils de Lyon (HCL), and evaluated the effectiveness of Nirsevimab against RSV-LRTI hospitalisation.

Acute Effects of Slow-Paced Breathing on Measures of HRV in Hospitalized Patients With Bilateral COVID-19 Pneumonia: A Secondary Analysis of a Randomized Clinical Trial.

Objective: Slow-paced breathing (SPB) with prolonged exhalation is assumed to stimulate vagal reflexes, which is represented by increased heart rate variability (HRV) values. However, most trials were conducted in healthy participants. We sought to evaluate the feasibility of SPB in hospitalized patients with confirmed bilateral COVID-19 pneumonia with major respiratory impairment and to investigate if SPB shows acute increasing effects on HRV measures in these severely ill patients with distinctly reduced vagal tone.

Process evaluation of an individually tailored complex intervention to improve activities and participation of older nursing home residents with joint contractures (JointConEval): a mixed-methods study.

Background: Older people with joint contractures in nursing homes often experience severe restrictions in their activities and participation. The effectiveness of an individually tailored complex intervention to improve residents' activities and participation by incorporating the biopsychosocial perspective into nursing care using a structured facilitator approach could not be established in the JointConEval cluster-randomised controlled trial. This process evaluation aimed to systematically identify factors influencing implementation and effectiveness.

Engineered packaging cell line for the enhanced production of baboon-enveloped retroviral vectors.

The baboon endogenous retrovirus (BaEV) glycoprotein is superior to the commonly used vesicular stomatitis virus glycoprotein (VSVg) for retroviral gene transfer into resting hematopoietic stem cells and lymphocyte populations. The derivative BaEVRLess (lacking the R domain) produces higher viral titers compared with wild-type BaEV, but vector production is impaired by syncytia formation and cell death of the HEK293T cells due to the high fusogenic activity of the glycoprotein. This lowers viral titers, leads to increased batch-to-batch variability, and impedes the establishment of stable packaging cell lines essential for the economical production of viral supernatants.

Reference Ranges and Determinants of Thyroid Function and TSH Receptor Antibodies During Early Pregnancy in Nepal.

The aims of this study were to (1) define population-based pregnancy-specific reference ranges for thyroid dysfunction during early pregnancy in Nepal and assess the impact of antibody positivity, (2) quantify the diagnostic impact of population-based reference ranges compared with current practice and (3) assess the determinants of thyroid function and antibody positivity.

Methods: A total of 800 healthy pregnant women aged 20-40 years in the Bhaktapur municipality were included.

Heterogeneity of Clinical Phenotypes in Severe Acute Respiratory Infections due to Respiratory Syncytial Virus: A Need to Look Beyond Hospitalization.

Objective: To use a pre-COVID-19 birth cohort database to describe the clinical heterogeneity of severe acute respiratory infections (SARI) cases of the past seasons as a basis to investigate further distribution of clinical phenotypes in the era of immunization for respiratory syncytial virus (RSV).

Study Design: Infants with RSV-SARI were identified from a 2014 through 2019 birth cohort in a tertiary care center in Lyon, France, and their medical records extensively reviewed. Using the criteria of the World Health Organization severity definitions, we classified SARI as having nutritional (inability to feed), respiratory (SpO<93%), or neurological (failure to respond, apneas) impairments.

Targeting metabolic dysfunction of CD8 T cells and natural killer cells in cancer.

The importance of metabolic pathways in regulating immune responses is now well established, and a mapping of the bioenergetic metabolism of different immune cell types is under way. CD8 T cells and natural killer (NK) cells contribute to cancer immunosurveillance through their cytotoxic functions and secretion of cytokines and chemokines, complementing each other in target recognition mechanisms. Several immunotherapies leverage these cell types by either stimulating their activity or redirecting their specificity against tumour cells.

Material And Methods: Our study was carried out on a laboratory strain and two BPI-related clinical strains, one of which surprisingly induced clinical symptoms of inflammation in the patient.

Text message intervention delivered from Australian general practices to improve breast cancer survivors' physical activity and cardiovascular risk factors: protocol for the EMPOWER-SMS-GP effectiveness implementation randomised controlled trial.

Introduction: Australian breast cancer survivors are at increased risk of cardiovascular disease and mortality, partly due to behavioural risk factors, including unhealthy diet and physical inactivity. Guidelines recommend health promotion delivered by general practitioners (GPs), but resources (ie, time and funding) are limited. Text message interventions sent from general practice to survivors may offer a low-resource solution but have not been evaluated.

A Large-Scale Serological Survey in Pets From October 2020 Through June 2021 in France Shows Significantly Higher Exposure to SARS-CoV-2 in Cats Compared to Dogs.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has the potential to infect various animals, including domestic pets like dogs and cats. Many studies have documented infection in companion animals by molecular and serological methods. However, only a few have compared seroprevalence in cats and dogs from the general population, and these studies were limited by small sample sizes and collections over short periods.

Current evidence gaps to support systematic cytomegalovirus screening in pregnancy.

The benefits of screening for cytomegalovirus (CMV) infection during pregnancy remain a topic of debate. To date, no randomized trial has compared the impact of screening versus routine management on the prevention of severe sequelae in newborns. Furthermore, it is unclear what actions can be taken in case of a positive screening given that there is limited evidence of effective interventions as no treatments showed significant effect on the frequency of congenital cytomegalovirus infections and, as additional challenge, the window for effective treatment initiation after maternal infection is narrow, estimated to be as short as five weeks.

Better cardiometabolic/inflammatory profile is associated with differences in the supraclavicular adipose tissue activity of individuals with T2DM.

Purpose: Brown adipose tissue (BAT), located in the supraclavicular region, has been associated with a better cardiometabolic profile and reduced risk of developing non-communicable chronic diseases (NCD), in addition to being associated with a healthier phenotype in obesity. However, it is unknown whether greater supraclavicular adipose tissue activity could be associated with a healthier metabolic profile in people already diagnosed with type 2 diabetes (T2DM). Thus, the present work evaluated if supraclavicular adipose tissue activity is associated with metabolic and molecular markers in individuals with T2DM.

Discovery and functional analysis of a novel ALPK1 variant in ROSAH syndrome.

Retinal dystrophy, optic nerve oedema, splenomegaly, anhidrosis and migraine headache (ROSAH) syndrome is an autosomal dominant disorder and to date is known to be caused by either the Thr237Met or Tyr254Cys variant in the protein kinase ALPK1. Here, we identify a family in which ROSAH syndrome is caused by a novel variant in which Ser277 is changed to Phe. All six patients examined display ocular inflammation and optic nerve elevation, four have retinal degeneration and four are registered blind.

Targeting n-myristoyltransferases promotes a pan-Mammarenavirus inhibition through the degradation of the Z matrix protein.

Several Old World and New World Mammarenavirus are responsible for hemorrhagic fever in humans. These enveloped viruses have a bi-segmented ambisense RNA genome that encodes four proteins. All Mammarenavirus identified to date share a common dependency on myristoylation: the addition of the C14 myristic acid on the N-terminal G2 residue on two of their proteins.
