Nanoparticle tracking analysis of natural hemozoin from Plasmodium parasites.

Background: Hemozoin is a byproduct of hemoglobin digestion crucial for parasite survival. It forms crystals that can be of interest as drug targets or biomarkers of malaria infection. However, hemozoin has long been considered as an amorphous crystal of simple morphology.

Patterns and determinants of cannabis use in youth visiting an urban emergency department in France.

Background: Cannabis use frequently starts during adolescence and young adulthood and can induce psychosocial and health consequences. Young people constitute hard-to-reach populations. Emergency departments could constitute a key care setting to identify cannabis use and its consequences among young people.

Restoring the Anatomy of Long Bones with Large Septic Non-Union Defects with the Masquelet Technique.

Septic non-union in long-bone fractures represents a challenging clinical entity. Management of lower extremity segmental bone defects, aiming to restore functional anatomy, remains extremely difficult and controversial. Masquelet technique is a reconstruction method for large diaphyseal bone defects, based on the notion of the induced membrane.

Effects of a physical activity and endometriosis-based education program delivered by videoconference on endometriosis symptoms: the CRESCENDO program (inCRease physical Exercise and Sport to Combat ENDOmetriosis) protocol study.

Background: Endometriosis is a chronic disease characterized by growth of endometrial tissue outside the uterine cavity which could affect 200 million women (The term "woman" is used for convenience. Individuals gendered as man or as nonbinary can also suffer from this disease) worldwide. One of the most common symptoms of endometriosis is pelvic chronic pain associated with fatigue.

ANTIFON-CLIC®, a new clinical decision support system for the treatment of invasive aspergillosis: is it clinically relevant?

Background: Invasive aspergillosis (IA) is increasing especially in new groups of patients. Despite advances in management, morbidity and mortality related to IA remain high. Thus, Clinical Decision Support System (CDSS) dedicated to IA are needed to promote the optimal antifungal for each group of patients.

Pharmacokinetic Consideration of Venetoclax in Acute Myeloid Leukemia Patients: A Potential Candidate for TDM? A Short Communication.

Background: Venetoclax (VNX)-based regimens have demonstrated significantly favorable outcomes in patients with acute myeloid leukemia (AML) and are now becoming the standard treatment. Tyrosine kinase inhibitors are administered at a fixed dose, irrespective of body surface area or weight. For such orally targeted therapies, real-world data have highlighted a larger pharmacokinetic (PK) interindividual variability (IIV) than expected.

[Inability of hospital computerised physician order entry systems to secure the use of concentrated potassium intravenous solutions].

Objectives: To determine whether hospital computerised physician order entry (CPOE) systems contribute to securing intravenous potassium chloride (KCl) prescriptions with reference to the recommendations issued by French healthcare agencies.

Methods: We sent a questionnaire to the members of the Association pour le Digital et l'Information en Pharmacie.

Results: More than three quarters of the 84 responses received involving 23 CPOE systems indicate that it is possible to: prescribe an ampoule of concentrated potassium chloride 10% 10mL intravenously without any diluents (80%); prescribe 4g of KCl in a bag of 500mL of NaCl 0,9% (98%); prescribe a solution that contains 6 grams of KCl per liter (94%); prescribe the administration of an injectable ampoule orally by means of a free text comment (83%).

Defining standard and high dosages for β-lactam agents administered by intermittent, prolonged or continuous infusion: a PK/PD simulation study.

Background: The new definitions of antimicrobial susceptibility categories proposed by EUCAST in 2020 require the definition of standard and high dosages of antibiotic. For injectable β-lactams, standard and high dosages have been proposed for short-infusion regimens only.

Objectives: To evaluate dosages for β-lactams administered by prolonged infusion (PI) and continuous infusion (CI).

[Nurses and prescribers' choice of an electric syringe pump protocol for intravenous heparin administration].

Objectives: Several protocols for administering heparin by electric syringe pump can coexist within the same hospital. This puts patients at risk of medication errors. In our hospital trust, two preparation protocols coexist (20000UI/48mL and 25000UI/50mL).

Healthcare worker protection against mpox contamination: position paper of the French Society for Hospital Hygiene.

In the context of the recent re-emergence of mpox worldwide, the French Society for Hospital Hygiene (SF2H) performed a literature review of the transmission paths and proposed specific recommendations for healthcare workers (HCWs) caring for patients with suspected or confirmed MPXV. In developed countries, the risk of contamination among HCWs in healthcare facilities seemed to be very low, limited to contamination through needle stick injuries. Two additional contamination cases were reported and not fully explained.

Daptomycin Exposure as a Risk Factor for Daptomycin-Induced Eosinophilic Pneumonia and Muscular Toxicity.

Background: High-dose daptomycin is increasingly used in patients with bone and joint infection (BJI). This raises concerns about a higher risk of adverse events (AEs), including daptomycin-induced eosinophilic pneumonia (DIEP) and myotoxicity. We aimed to examine pharmacokinetic and other potential determinants of DIEP and myotoxicity in patients with BJI receiving daptomycin.

Novel UL23 and UL30 substitutions in HSV1 and HSV2 viruses related to polymorphism or drug resistance.

Data on herpes simplex virus (HSV) polymorphism as well as acyclovir (ACV) and foscarnet (FOS) resistance mutations are not exhaustive and may hinder accurate diagnosis by next-generation sequencing (NGS). Here, we report novel UL23 and UL30 substitutions for HSV1 and HSV2 identified in immunocompromised patients treated for hematological malignancies during the last 6 years of HSV resistance surveillance at the University Hospital of Lyon. For HSV1, 35 novel UL23 substitutions and 52 novel UL30 substitutions were identified.

Chronic pain characteristics in COVID-19 survivors after an ICU stay. A cross-sectional study.

Background: The onset and characteristics of chronic pain following an intensive care unit (ICU) stay for COVID-19 have never been thoroughly investigated.

Study Design: A multicenter cohort study was conducted to describe chronic pain, according to ICD-11, among COVID-19 survivors. The chronic pain was assessed during face-to-face consultations with a pain specialist.

Screening problematic use of substances among young subjects attending an emergency department, and subsequent treatment seeking.

Introduction: Young individuals constitute a key population for the screening of problematic use of substances (PUS), but they are not likely to seek support and are hard to reach. Targeted screening programs should thus be developed in the places of care they may attend for other reasons, including emergency departments (EDs). We aimed to explore the factors associated with PUS in young people attending an ED; we measured the subsequent access to addiction care after ED screening.

Outcome of patients with cystic fibrosis colonized by Scedosporium and Lomentospora species: A longitudinal cohort study.

Scedosporium and Lomentospora species rank second among the filamentous fungi colonizing the airways of cystic fibrosis (CF) patients. These fungi could be responsible for allergic bronchopulmonary mycosis (ABPM) and bronchitis before lung transplantation and invasive infections after. However, their role in CF lung disease is debated.

IVIg therapy in the management of BK virus infections in pediatric kidney transplant patients.

BK virus-associated nephropathy (BKPyVAN) induces kidney allograft dysfunction. Although decreasing immunosuppression is the standard for managing BK virus (BKPyV) infection, this strategy is not always effective. The use of polyvalent immunoglobulins (IVIg) may be of interest in this setting.
