Neuropathological and cerebrospinal fluid correlates of choroid plexus inflammation in progressive multiple sclerosis.

Among the intrathecal inflammatory niches where compartmentalized inflammation persists and plays a pivotal role in progressive multiple sclerosis (MS), choroid plexus (CP) has recently received renewed attention. To better characterize the neuropathological/molecular correlates of CP in progressive MS and its potential link with other brain inflammatory compartments, such as perivascular spaces and leptomeninges, the levels, composition and phenotype of CP immune infiltration in lateral ventricles of the hippocampus were examined in 40 post-mortem pathologically confirmed MS and 10 healthy donors, using immunochemistry/immunofluorescence and in-situ sequencing. Significant inflammation was detected in the CP of 21 out of the 40 MS cases (52%).

Tools, techniques, and challenges in preparing cytology specimens for ancillary studies: results of the ASC Optimizing Cytology and Small Biopsy Specimen Processing for Ancillary Studies task force survey.

Introduction: Ancillary testing on cytopathology and other small biopsy specimens is crucial for diagnosis and provides critical information to clinicians. Testing is dependent on preanalytic factors and would benefit from standardization of specimen collection protocols across laboratories. To assess institutional practices and areas of need for evidence-based standards, we surveyed current practices across cytopathology laboratories.

Multifrequency-STD NMR unveils the first Michaelis complex of an intramolecular trans-sialidase from Ruminococcus gnavus.

RgNanH is an intramolecular trans-sialidase expressed by the human gut symbiont Ruminococcus gnavus, to utilise intestinal sialylated mucin glycan epitopes. Its catalytic domain, belonging to glycoside hydrolase GH33 family, cleaves off terminal sialic acid residues from mucins, releasing 2,7-anhydro-Neu5Ac which is then used as metabolic substrate by R. gnavus to proliferate in the mucosal environment.

Analyzing assisted reproductive treatment representations in Italy and Spain through newspapers.

With the increase in infertility cases recorded over the last 20 years, there is a considerable demand for assisted reproductive treatments (ART). However, there is significant variation in the availability of such treatments across different countries. Legislation on assisted reproduction is influenced by various cultural expressions, making it seemingly impossible to create a single representation adaptable to different contexts.

Non-binary narratives: subjectivation and lived experiences in contemporary Italy.

This paper explores the processes of individual and collective subjectivation experienced by non-binary individuals living in contemporary Italy. Using qualitative methods, the study, which was conducted between July and September 2021, involved a sample of twenty-six young adults aged between eighteen and thirty years. Starting from participants' narratives, the thematic analysis revealed the significance of both physical and virtual support environments in the subjectivation process, taking into account the diverse micro-contexts in which people live.

The role of new inflammatory indices in the prediction of endoscopic and histological activity in inflammatory bowel disease patients.

Background And Aim: Inflammatory indices are promising indicators that can be used to evaluate inflammation in inflammatory bowel diseases (IBDs). The present study aimed to investigate the test accuracy of several inflammatory indices to identify endoscopic, and histological activity in a cohort of IBD patients.

Study: All IBD patients who underwent colonoscopy and blood examination (within 4 weeks and without therapeutic change) were included.

Chemosensory assessment and impact on quality of life in neurosensorial cluster of the post COVID 19 syndrome.

COVID-19 pandemic brought chemosensory impairment to the forefront of medicine, revealing gaps in the knowledge of pathophysiological mechanisms, true prevalence and preventive/therapeutic alternatives. This is a sub-study of the ORCHESTRA cohort focusing on post-COVID-19 chemosensory symptoms. Risk factors for neurosensorial cluster of post-COVID-19 syndrome (NSc-PCS) were assessed through multivariable analysis.

IBD Patients with Primary or Secondary Nonresponse to Ustekinumab Benefit from Dose Escalation or Reinduction.

Ustekinumab is a monoclonal antibody approved for the treatment of IBD. This drug has a well-established efficacy; however, patients may not respond or lose response. The availability of other biological therapies prompts the need for comparative data between different agents to suggest first- or second-line strategies.

Fast Quantitative Validation of 3D Models of Low-Affinity Protein-Ligand Complexes by STD NMR Spectroscopy.

Low-affinity protein-ligand interactions are important for many biological processes, including cell communication, signal transduction, and immune responses. Structural characterization of these complexes is also critical for the development of new drugs through fragment-based drug discovery (FBDD), but it is challenging due to the low affinity of fragments for the binding site. Saturation transfer difference (STD) NMR spectroscopy has revolutionized the study of low-affinity receptor-ligand interactions enabling binding detection and structural characterization.

The cultural representations and symbolizations emerging from Italian psychologists working in multidisciplinary assisted reproduction teams: A linguistic analysis with the emotional text mining.

This study aims to explore the perspectives of Italian psychologists who work in assisted reproductive treatment (ART) centres regarding their roles within multidisciplinary teams. Twenty-eight psychologists were interviewed, recorded and their transcribed text was analysed using emotional text mining. The analysis revealed four clusters representing the psychologists' cultural symbolizations of their works: 'Clinical Practice with the patient', 'Placing Psychology within the Treatment', 'Psychologist's Loneliness' and; 'Collusion with Medicine'.

Computational scoring and experimental evaluation of enzymes generated by neural networks.

In recent years, generative protein sequence models have been developed to sample novel sequences. However, predicting whether generated proteins will fold and function remains challenging. We evaluate a set of 20 diverse computational metrics to assess the quality of enzyme sequences produced by three contrasting generative models: ancestral sequence reconstruction, a generative adversarial network and a protein language model.

Benchmarking cytology support for ROSE during endoscopic and bronchoscopic procedures.

Introduction: There has been an increase in endoscopic and bronchoscopic biopsies as minimally invasive methods to obtain specimens from gastrointestinal (GI) or pancreatobiliary lesions and thoracic or mediastinal lesions, respectively. As hospitals undertake more of these procedures, it is important to consider the staffing implications that this has on cytopathology laboratories with respect to support for rapid on-site evaluation (ROSE).

Materials And Methods: Volume and time data from endoscopic ultrasound and bronchoscopic procedures (including endobronchial ultrasound-guided transbronchial needle aspirations and small biopsies with touch preparation) in the GI suite, bronchoscopy suite, or operating room were reviewed for 2 months at 2 different medical centers with ROSE services provided by cytologists or fellows physically present at the procedure and cytopathologists located remotely using telecytology.

COVID-19 post-traumatic stress disorder: the role of ACEs, alexithymia, and attachment in the Italian population.

Objective: The COVID-19 pandemic is considered a collective traumatic event. Several studies have highlighted high levels of post-traumatic stress disorder (PTSD) symptoms among the general population during the pandemic. The general aim of this research is to explore the role of adverse childhood experiences (ACEs), alexithymia, and anxiety and avoidance attachment dimensions as risk factors that are making individuals more vulnerable to PTSD-COVID-related symptoms.

Cluster analysis and visualisation of electronic health records data to identify undiagnosed patients with rare genetic diseases.

Rare genetic diseases affect 5-8% of the population but are often undiagnosed or misdiagnosed. Electronic health records (EHR) contain large amounts of data, which provide opportunities for analysing and mining. Data mining, in the form of cluster analysis and visualisation, was performed on a database containing deidentified health records of 1.
