Material And Methods:  Plasma and serum samples from V617F MPN patients with (n=26) or without (n=7) thrombotic debut and different treatments, were obtained (n=33).

Exploring the Relationship Between Humoral and Cellular T Cell Responses Against SARS-CoV-2 in Exposed Individuals From Emilia Romagna Region and COVID-19 Severity.

COVID-19 remains a significant global health problem with uncertain long-term consequences for convalescents. We investigated the relationships between anti-N protein antibody levels, severe acute respiratory syndrome (SARS)-CoV-2-associated TCR repertoire parameters, HLA type and epidemiological information from three cohorts of 524 SARS-CoV-2-infected subjects subgrouped in acute phase, seronegative and seropositive convalescents from the Emilia Romagna region. Epidemiological information and anti-N antibody index were associated with TCR repertoire data.

A sweeping view of avian mycoplasmas biology drawn from comparative genomic analyses.

Background: Avian mycoplasmas are small bacteria associated with several pathogenic conditions in many wild and poultry bird species. Extensive genomic data are available for many avian mycoplasmas, yet no comparative studies focusing on this group of mycoplasmas have been undertaken so far.

Results: Here, based on the comparison of forty avian mycoplasma genomes belonging to ten different species, we provide insightful information on the phylogeny, pan/core genome, energetic metabolism, and virulence of these avian pathogens.

Comparison of nasal swabs and handmade foam cubes for detecting equine herpesvirus 5 (EHV-5) by quantitative polymerase chain reaction (qPCR).

The control of equine respiratory infections is a biosecurity challenge. Respiratory viruses are often rapidly detected using quantitative polymerase chain reaction (qPCR) on nasal swabs. In the past, some laboratories developed handmade techniques to increase the amount of nasal secretions collected, without comparing them with nasal swabs when qPCR replaced the use of viral culture.

Circulating extracellular vesicles and neutrophil extracellular traps contribute to endothelial dysfunction in preeclampsia.

Background: Preeclampsia (PE) is a pregnancy complication characterized by hypertension, proteinuria, endothelial dysfunction, and complement dysregulation. Placenta-derived extracellular vesicles (EVs), necessary in maternal-fetal communication, might contribute to PE pathogenesis. Moreover, neutrophil extracellular traps (NETs) play a pathogenic role in other complement-mediated pathologies, and their contribution in PE remains unexplored.

24-hour isolated aortic systolic hypertension phenotype and its association with carotid and cardiac damage: the SAFAR study.

The prevalence of systolic hypertension phenotypes based on simultaneous 24-h brachial (br) and aortic (ao) ambulatory blood pressure monitoring (ABPM) remains unknown. We sought to describe their prevalence and associations with hypertension mediated organ damage (HMOD). Participants with 24-h br and ao ABPM, carotid ultrasound and echocardiography data were categorized into 4 systolic hypertension phenotypes: sustained systolic br and ao normotension (SSN), isolated br systolic hypertension (IbrSH), isolated ao systolic hypertension (IaoSH) and sustained br and ao systolic hypertension (SSH).

ESR Essentials: Image evaluation of patients with seizures and epilepsy-practice recommendations by the European Society of Neuroradiology.

Epilepsy, a neurological disorder characterised by recurrent seizures, poses significant challenges in diagnosis, treatment, and management. Understanding the underlying causes and identifying precise anatomical locations of epileptogenic foci are critical for effective management strategies, particularly in drug-resistant patients. Neuroimaging techniques, particularly magnetic resonance (MR), play a pivotal role in the evaluation of epilepsy patients, offering insights into structural abnormalities, epileptogenic lesions, and functional alterations within the brain.

Burden of Cardio-Cerebrovascular and Renal Diseases Attributable to Systolic Hypertension in France in 2021.

Background: Hypertension is the most common chronic disease and a major modifiable risk factor for cardio-cerebrovascular and renal diseases. This study estimated the national burden of hypertension, defined as systolic blood pressure ≥140 mm Hg, on morbidity and mortality in 2021 in France.

Methods: For all diseases causally associated with hypertension (cardiovascular diseases, chronic kidney diseases, and dementia), the number and proportion of cases attributable to hypertension in adults aged ≥35 years were estimated using population attributable fractions.
