Treatment of Venous Thromboembolism with Edoxaban over 18 Months: Results from ETNA-VTE Europe.

Background:  The benefits and risks of extending anticoagulant treatment beyond the first 3 to 6 months in patients with venous thromboembolism (VTE) in clinical practice are not well understood.

Methods:  ETNA-VTE Europe is a prospective, noninterventional, post-authorization study in unselected patients with VTE treated with edoxaban in eight European countries for up to 18 months. Recurrent VTE, major bleeding, and all-cause death were the primary study outcomes.

Complexity and recurrence of body surface electrocardiograms correlate with estimated reentrant atrial activity using electrocardiographic imaging in atrial fibrillation patients.

Background: Complexity and signal recurrence metrics obtained from body surface potential mapping (BSPM) allow quantifying atrial fibrillation (AF) substrate complexity. This study aims to correlate electrocardiographic imaging (ECGI) detected reentrant patterns with BSPM-calculated signal complexity and recurrence metrics.

Methods: BSPM signals were recorded from 28 AF patients (17 male, 11 women, 62.

Intranasally administrated fusion-inhibitory lipopeptides block SARS-CoV-2 infection in mice and enable long-term protective immunity.

We have assessed antiviral activity and induction of protective immunity of fusion-inhibitory lipopeptides derived from the C-terminal heptad-repeat domain of SARS-CoV-2 spike glycoprotein in transgenic mice expressing human ACE2 (K18-hACE2). The lipopeptides block SARS-CoV-2 infection in cell lines and lung-derived organotypic cultures. Intranasal administration in mice allows the maintenance of homeostatic transcriptomic immune profile in lungs, prevents body-weight loss, decreases viral load and shedding, and protects mice from death caused by SARS-CoV-2 variants.

International consensus guidelines on the implementation and monitoring of vosoritide therapy in individuals with achondroplasia.

Achondroplasia is the most common genetic form of short-limbed skeletal dysplasia (dwarfism). Clinical manifestations and complications can affect individuals across the lifespan, including the need for adaptations for activities of daily living, which can affect quality of life. Current international guidelines focus on symptomatic management, with little discussion regarding potential medication, as therapeutic options were limited at the time of their publication.

Establishing bio-logging data collections as dynamic archives of animal life on Earth.

Rapid growth in bio-logging-the use of animal-borne electronic tags to document the movements, behaviour, physiology and environments of wildlife-offers opportunities to mitigate biodiversity threats and expand digital natural history archives. Here we present a vision to achieve such benefits by accounting for the heterogeneity inherent to bio-logging data and the concerns of those who collect and use them. First, we can enable data integration through standard vocabularies, transfer protocols and aggregation protocols, and drive their wide adoption.

The spatially informed mFISHseq assay resolves biomarker discordance and predicts treatment response in breast cancer.

Current assays fail to address breast cancer's complex biology and accurately predict treatment response. On a retrospective cohort of 1082 female breast tissues, we develop and validate mFISHseq, which integrates multiplexed RNA fluorescent in situ hybridization with RNA-sequencing, guided by laser capture microdissection. This technique ensures tumor purity, unbiased whole transcriptome profiling, and explicitly quantifies intratumoral heterogeneity.

Prevention of Stroke in Intracerebral Haemorrhage Survivors with Atrial Fibrillation: Rationale and Design for PRESTIGE-AF Trial.

Adequate secondary prevention in survivors of intracerebral hemorrhage (ICH) who also have atrial fibrillation (AF) is a long-standing clinical dilemma because these patients are at increased risk of recurrent ICH as well as of ischemic stroke. The efficacy and safety of oral anticoagulation, the standard preventive medication for ischemic stroke patients with AF, in ICH patients with AF are uncertain. PRESTIGE-AF is an international, phase 3b, multi-center, randomized, open, blinded end-point assessment (PROBE) clinical trial that compared the efficacy and safety of direct oral anticoagulants (DOACs) with no DOAC (either no antithrombotic treatment or any antiplatelet drug).

The monogenic landscape of human infectious diseases.

The spectrum of known monogenic inborn errors of immunity is growing, with certain disorders underlying a specific and narrow range of infectious diseases. These disorders reveal the core mechanisms by which these infections occur in various settings, including inherited and acquired immunodeficiencies, thereby delineating the essential mechanisms of protective immunity to the corresponding pathogens. These findings also have medical implications, facilitating diagnosis and improving the management of individuals at risk of disease.

The secondary purposes were to analyze clinical and technical factors that may affect accuracy and testing the method in a realistic setting, with MR-guided Laser ablation on an ex vivo muscle sample.

Materials And Methods: An ex vivo muscle sample was subjected to Laser ablation while using a two-dimensional multislice segmented echo planar imaging sequence for MR thermometry.

A Machine Learning Model to Harmonize Volumetric Brain MRI Data for Quantitative Neuroradiologic Assessment of Alzheimer Disease.

Purpose To extend a previously developed machine learning algorithm for harmonizing brain volumetric data of individuals undergoing neuroradiologic assessment of Alzheimer disease not encountered during model training. Materials and Methods Neuroharmony is a recently developed method that uses image quality metrics as predictors to remove scanner-related effects in brain-volumetric data using random forest regression. To account for the interactions between Alzheimer disease pathology and image quality metrics during harmonization, the authors developed a multiclass extension of Neuroharmony for individuals with and without cognitive impairment.

Taxonomic revision of Mozambique dung beetle species in the genus Diastellopalpus van Lansberge, 1886 (Coleoptera: Scarabaeidae: Scarabaeinae).

Recently, there has been growing attention paid to the Mozambican dung beetle fauna, including the description of several new species. In this paper, we revise the taxonomy of species recorded from Mozambique in the genus Diastellopalpus van Lansberge, 1886, including the description of Diastellopalpus scholtzi Daniel, Strümpher, Josso & Davis, new species. We also report a new country record for Diastellopalpus neavei (d'Orbigny, 1914).

Global epidemiology of serogroup Y invasive meningococcal disease: a literature review.

Serogroup epidemiology of invasive meningococcal disease (IMD) is constantly evolving, varying by time and location. Surveillance reports have indicated a rise in meningococcal serogroup Y (MenY) in some regions in recent years. This systematic literature review explores the evolving epidemiology of MenY IMD globally based on review of recent articles and national surveillance reports published between 1 January 2010 and 25 March 2021.

Raising the bar in ulcerative colitis management.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by growing incidence and prevalence around the world in the last few decades. The range of available existing treatment and strategies for its management is being implemented. Given the introduction of newly developed molecules and the lack of specific guidelines, drug positioning may represent a tough clinical challenge.

Incidence of SARS-CoV-2 Infection Among European Healthcare Workers and Effectiveness of the First Booster COVID-19 Vaccine, VEBIS HCW Observational Cohort Study, May 2021-May 2023.

European countries have included healthcare workers (HCWs) among priority groups for COVID-19 vaccination. We established a multi-country hospital network to measure the SARS-CoV-2 incidence and effectiveness of COVID-19 vaccines among HCWs against laboratory-confirmed SARS-CoV-2 infection. HCWs from 19 hospitals in 10 countries participated in a dynamic prospective cohort study, providing samples for SARS-CoV-2 testing at enrolment and during weekly/fortnightly follow-up.

Heterogeneous intratumor irradiation: a new partner for immunotherapy.

We recently demonstrated that a heterogeneous tumor irradiation strategy, combining high-dose and low-dose radiotherapy (RT) within the same tumor volume, can synergize with immunotherapy in mice. Our findings indicate that heterogeneous RT doses may promote the spatial diversification of the antitumor immune response. Spatial fractionation of the RT dose has the potential to enhance the therapeutic index of RT/IO combinations, particularly in scenarios where irradiating the entire tumor volume is unfeasible or excessively harmful to the patient.

Catheter Ablation or Antiarrhythmic Drugs for Ventricular Tachycardia.

Background: Patients with ventricular tachycardia and ischemic cardiomyopathy are at high risk for adverse outcomes. Catheter ablation is commonly used when antiarrhythmic drugs do not suppress ventricular tachycardia. Whether catheter ablation is more effective than antiarrhythmic drugs as a first-line therapy in patients with ventricular tachycardia is uncertain.

Structural variation in the pangenome of wild and domesticated barley.

Pangenomes are collections of annotated genome sequences of multiple individuals of a species. The structural variants uncovered by these datasets are a major asset to genetic analysis in crop plants. Here we report a pangenome of barley comprising long-read sequence assemblies of 76 wild and domesticated genomes and short-read sequence data of 1,315 genotypes.

Multi-strain modeling of influenza vaccine effectiveness in older adults and its dependence on antigenic distance.

Influenza vaccine effectiveness (VE) varies seasonally due to host, virus and vaccine characteristics. To investigate how antigenic matching and dosage impact VE, we developed a mechanistic knowledge-based mathematical model. Immunization with a split vaccine is modeled for exposure to A/H1N1 or A/H3N2 virus strains.

Multimodal Assessment of the Origin of Myoclonus in Lance-Adams Syndrome.

Background And Objectives: Lance-Adams syndrome (LAS), or chronic posthypoxic myoclonus, is a long-term disabling neurologic disorder occurring in survivors of anoxia. The cortical or subcortical origin of this myoclonus is unclear. We aimed to identify the neuroanatomical origin of myoclonus in LAS.

Development and validation of the post-CAR prognostic index for large B-cell lymphoma patients after CAR-T progression in third or later line treatment.

Chimeric antigen receptor (CAR) T-cell therapy fails to achieve durable responses in over 60% of relapsed/refractory (R/R) large B-cell lymphoma (LBCL) patients in the third or later line setting. After CAR-T failure, survival outcomes are heterogeneous and a prognostic model in this patient population is lacking. A training cohort of 216 patients with progressive disease (PD) after CAR-T from 12 Spanish centers was used to develop the Post-CAR Prognostic Index (PC-PI); primary endpoint was overall survival (OS) from CAR-T progression.

Deciphering the effects of STN DBS on neuropsychiatric fluctuations in Parkinson's disease.

The impact of subthalamic nucleus (STN) deep brain stimulation (DBS) on neuropsychiatric fluctuations in Parkinson´s disease (PD) remains unclear. The Neuropsychiatric Fluctuations Scale (NFS) can help to fill this gap, directly measuring fluctuations between the OFF- and ON-medication conditions. The NFS provides NFS-plus (hyperdopaminergic) and NFS-minus (hypodopaminergic) sub-scores.

Duration of anticoagulation for venous thromboembolism in pediatric patients: Evaluation of the Duration of Therapy for Thrombosis in Children (Kids-DOTT) trial outcomes at 2 years.

Background: The Multicenter Evaluation of the Duration of Therapy for Thrombosis in Children multinational, randomized clinical trial revealed noninferiority of a 6-week vs 3-month duration of anticoagulation for the treatment of provoked venous thromboembolism (VTE) in patients <21 years old in regard to net clinical benefit at 1 year.

Objectives: To evaluate noninferiority at 2 years.

Methods: Patients whose repeat imaging 6 weeks after VTE diagnosis did not show complete veno-occlusion were randomized to discontinue anticoagulation vs receive a total 3-month course and followed for 2 years for the occurrence of symptomatic recurrent VTE (efficacy outcome) and clinically relevant bleeding (safety outcome).
