A Pooled Pharmacokinetic Analysis for Piperacillin/Tazobactam Across Different Patient Populations: From Premature Infants to the Elderly.

Background And Objectives: The pharmacokinetics (PK) of piperacillin/tazobactam (PIP/TAZ) is highly variable across different patient populations and there are controversies regarding non-linear elimination as well as the fraction unbound of PIP (f). This has led to a plethora of subgroup-specific models, increasing the risk of misusing published models when optimising dosing regimens. In this study, we aimed to develop a single model to simultaneously describe the PK of PIP/TAZ in diverse patient populations and evaluate the current dosing recommendations by predicting the PK/pharmacodynamics (PD) target attainment throughout life.

Life cycle and morphogenetic differentiation in heteromorphic cell types of a cosmopolitan marine microalga.

Gephyrocapsa huxleyi is a prevalent, bloom-forming phytoplankton species in the oceans. It exhibits a complex haplodiplontic life cycle, featuring a diploid-calcified phase, a haploid phase and a third 'decoupled' phase produced during viral infection. Decoupled cells display a haploid-like phenotype, but are diploid.

A pipeline for validation of Serendipita indica effector-like sRNA suggests cross-kingdom communication in the symbiosis with Arabidopsis.

Bidirectional communication between pathogenic microbes and their plant hosts via small (s)RNA-mediated cross-kingdom RNA interference (ckRNAi) is a key element for successful host colonisation. Whether mutualistic fungi of the Serendipitaceae family, known for their extremely broad host range, use sRNAs to colonize plant roots is still under debate. To address this question, we developed a pipeline to validate the accumulation, translocation, and activity of fungal sRNAs in post-transcriptional silencing of Arabidopsis thaliana genes.

Cost-effectiveness of ten commonly used antipsychotics in first-episode schizophrenia in the UK: economic evaluation based on a discrete event simulation model.

Background: Previous economic evidence about interventions for schizophrenia is outdated, non-transparent and/or limited to a specific clinical context.

Aims: We developed a discrete event simulation (DES) model for estimating the cost-effectiveness of interventions in schizophrenia in the UK.

Method: The DES model was developed based on the structure of previous models, populated with demographic, clinical and cost data from the UK, and antipsychotics' effects from recent network meta-analyses.

Correlation Analysis Between Cortical Structural Features and Acoustic Features in Patients With Parkinson's Disease.

Purpose: Parkinson disease (PD) is a progressive neurodegenerative disease. The aim of this study is to investigate the association between acoustic and cortical brain features in Parkinson's disease patients.

Methods: We recruited 19 (eight females, 11 males) Parkinson's disease patients and 19 (eight females, 11 males) healthy subjects to participate in the experiment.

Time to Refine Prostate Cancer Epidemiology: Defining New Endpoints for Effective Screening and Causal Epidemiological Studies.

Current epidemiological indicators reflect the prevalence of prostate-specific antigen (PSA) testing rather than the actual incidence of clinically significant prostate cancer. These indicators are also biased because of the variability of the PSA test. We therefore need to adopt new reliable criteria in causal epidemiological studies and screening programs.

[VEXAS-like auto inflammatory syndrome: 2 cases].

Introduction: VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic), recently described, due to a somatic mutation of the UBA1 gene and often associated with hemopathy, is characterized by systemic symptoms close to those described in Still's disease or relapsing polychondritis. There are also patients with hemopathy, presenting inflammatory symptoms reminiscent of those of VEXAS syndrome but without mutation of the UBA1 gene.

Case/discussion: Two male patients consulted for general signs, dermatological symptoms, arthralgia, chondritis and venous thrombosis, like patients in the French cohort suffering from VEXAS syndrome.

Acceptability patterns of hypothetic taxes on different types of foods in France.

Objective: To identify patterns of food taxes acceptability among French adults, and to investigate population characteristics associated with them.

Design: Cross-sectional data from the NutriNet-Santé e-cohort. Participants completed an ad-hoc web-based questionnaire to test patterns of hypothetical food taxes acceptability (i.

Gender and geographical bias in the editorial decision-making process of biomedical journals: a case-control study.

Objectives: To assess whether the gender (primary) and geographical affiliation (post-hoc) of the first and/or last authors are associated with publication decisions after peer review.

Design: Case-control study.

Setting: Biomedical journals.

Distinct pathophysiological pathways support stratification of Sjögren's disease based on symptoms, clinical, and routine biological data.

Objective: Recently, three distinct phenotypes of Sjögren's disease (SjD) patients have been described, based on cluster analysis: B-cell active with low symptoms (BALS), high systemic activity (HSA), and low systemic activity with high symptoms (LSAHS). We aimed to assess whether these clusters were associated with distinct biomarkers and the prognostic value of IFN signature.

Methods: The ASSESS cohort is a 20-year prospective cohort of SjD patients.

Development of a Specific Fluorescence Post-column Derivatization Method Coupled with Ion-Pair Chromatography for Phytate Analysis in Food.

Phytate in plants (inositol phosphates, InsPs) affects mineral bioavailability. However, methods for their quantification may lead to variable results, and some are nonspecific (spectrophotometric techniques). In this study, ion-pair high-performance liquid chromatography (HPLC) was coupled with post-column derivatization to allow fluorescence detection (FLD, λ324/λ364 nm) of InsPs.

A general strategy for engineering GU base pairs to facilitate RNA crystallization.

X-ray crystallography is a fundamental technique that provides atomic-level insights into RNA structures. However, obtaining crystals of RNA structures diffracting to high resolution is challenging. We introduce a simple strategy to enhance the resolution limit of RNA crystals by the selective substitution of Watson-Crick pairs by GU pairs within RNA sequences.

Heterozygous UBR5 variants result in a neurodevelopmental syndrome with developmental delay, autism, and intellectual disability.

E3 ubiquitin ligases have been linked to developmental diseases including autism, Angelman syndrome (UBE3A), and Johanson-Blizzard syndrome (JBS) (UBR1). Here, we report variants in the E3 ligase UBR5 in 29 individuals presenting with a neurodevelopmental syndrome that includes developmental delay, autism, intellectual disability, epilepsy, movement disorders, and/or genital anomalies. Their phenotype is distinct from JBS due to the absence of exocrine pancreatic insufficiency and the presence of autism, epilepsy, and, in some probands, a movement disorder.

Active biomonitoring of river pollution using an ex-situ exposure system with two model species.

In the context of increasing pollution pressure on aquatic ecosystems, it is essential to improve our knowledge of habitat quality and its suitability for organisms. It is particularly relevant to better integrate early life stages of fish into pollution biomonitoring programs, as they are reliable indicators of ecosystem integrity and because of their high sensitivity to pollutants. To avoid the influence of environmental parameters on their development, a lab-on-field approach, called the ex-situ exposure method, was developed.

The association between social comparison in social media, body image concerns and eating disorder symptoms: A systematic review and meta-analysis.

Research has found that high social media use is associated with a greater tendency to compare oneself with others, which in turn may heighten body image concerns and problematic eating behaviours. The aim of this systematic review and meta-analysis was to examine the mean association between online social comparison and body image concerns, eating disorder behaviours and positive body image. Eligible articles published between 2008 and 2024 were searched for in scientific databases.

Benefits of swaying while standing to higher selective attention in goal-directed visual tasks.

Background And Aim: Sit-stand desks allow individuals to work in either sitting or standing position. While previous studies have reported better performance on the attention network test (ANT) while standing compared to sitting, the relationship between body sway induced by these positions and ANT performance remains unclear. In this study, we aimed to test and expect benefits of body sway (in terms of magnitude and complexity) and improvements in ANT performance when standing (e.

Optimization of an analytical method based on the use of zwitterionic- phosphorylcholine -HILIC column for the determination of multiple polar emerging contaminants in reclaimed water.

The aim of this study was to optimize a Liquid Chromatography Mass Spectrometry (LC-MS) method using a zwitterionic phosphorylcholine HILIC column for the determination of several Persistent and Mobile Organic Contaminants (PMOC) in wastewater samples. An experimental design approach was implemented to both better understand the retention mechanisms of several polar compounds and to find the optimal operating conditions for their detection and quantification. Eleven PMOCs, with logD ranging from -5.

Upper airway obstructive events on noninvasive ventilation in NMD adolescents.

Home noninvasive ventilation (NIV) is expanding worldwide for pediatrics and is mainly indicated to treat nocturnal alveolar hypoventilation. Nasal mask is the most common interface used in children, but oronasal mask may be indicated in case of excessive mouth leaks or facial weakness. Obstructive events caused by the oronasal mask have been reported in a few studies on adult patients, but never in pediatrics.

Evolution of breast cancer management after mediastinal hodgkin lymphoma: Towards a breast- conserving approach.

Purpose: To analyse the clinical and histological characteristics of breast cancers (BC) occurring after Hodgkin lymphoma (HL), as well as their outcome with particular attention to the effectiveness and safety of breast-conservative surgery with radiation therapy (RT).

Materials And Methods: This is a retrospective study of 218 patients who developed stage 0 to III BC after treatment for mediastinal HL between 1951 and 2022. Comprehensive demographic, clinical, and therapeutic data were collected for HL and BC, as well as survival and locoregional control.

Homonuclear decoupled INADEQUATE NMR methods with improved sensitivity and resolution in solid-state NMR.

The two-dimensional (2D) refocused INADEQUATE NMR experiment, which correlates double-quantum (DQ) and single-quantum (SQ) coherences, is widely used to probe the chemical connectivities in solids. Nevertheless, the multiplets along the F dimension reduce the resolution and sensitivity of this experiment. The Composite-Refocusing (CR) technique with two excitation pulses has been proposed to suppress these multiplets in 2D INADEQUATE spectra of liquids.

An update on access to novel treatment for metastatic melanoma in Europe - A 2024 survey of the European melanoma registry and the European association of dermato-oncology.

Advances in cancer treatments have significantly improved their effectiveness, yet access to first-line therapies remains limited. A 2017 survey revealed that over 25 % of metastatic melanoma patients in Europe lacked access to recommended therapies. To address this, the European Association of Dermato-Oncology and the European Melanoma Registry conducted a follow-up study on the registration and reimbursement of first-line treatments.
