No association was identified between prior influenza vaccine and bacterial coinfection in patients admitted to the ICU due to severe influenza. Post influenza vaccination studies are necessary to continue evaluating the possible benefits.

No association was identified between prior influenza vaccine and bacterial coinfection in patients admitted to the ICU due to severe influenza. Post influenza vaccination studies are necessary to continue evaluating the possible benefits.Healthcare utilisation and expenditure are highly concentrated in hospital inpatient services, in particular in end-of-life care with the peak occurring in the very last year of life, regardless of patient age. Few scientific studies have investigated hospital costs and stays of patients at the end of life, and even fewer studies have analysed their evolution over time. In this paper, we exploit hospitalisation data for the Lombardy region of Italy with the aim of studying the evolution of hospital casemix, costs and stays of chronic patients, and compare the last year of life of two cohorts of patients who died in 2005 and 2014. Despite an overall three-year increase in the age at death, the results showed a significant decrease in hospital costs and use due to reduced interventions and length of hospital stays. However, this was not associated with an increase in quality of life/conditions (as indicated by clinical casemix as a proxy) for end-of-life patients; patients' casemix characteristics and clinical condition, as measured by the number of comorbidities, disease severity, prevalence of pulmonary disease and heart failure diagnosis, significantly worsened over the decade. This gives rise to important health policy concerns on how to identify effective policies and possible changes in healthcare system organisation to move from hospital-centred care to a community-centred approach whose value has been demonstrated during the COVID-19 pandemic.

Blau syndrome (BS) is an autoinflammatory disease associated with mutations in nucleotide-binding oligomerization domain 2. Although treatments with anti-TNF agents have been reported to be effective, the underlying molecular mechanisms remain unclear.

We aimed to elucidate the mechanisms of autoinflammation in patients with BS and to clarify how anti-TNF treatment controls the disease phenotype at the cellular level in clinical samples.

Macrophages were differentiated from monocytes of 7 BS patients, and global transcriptional profiles of 5 patients were analyzed with or without IFN-γ stimulation. Macrophages were also generated from BS-specific induced pluripotent stem cells (iPSCs), and their transcriptome was examined for comparison.

Aberrant inflammatory responses were observed upon IFN-γ stimulation in macrophages from untreated BS patients, but not in those from patients treated with anti-TNF. iPSC-derived macrophages carrying a disease-associated mutation also showed IFN-γ-dependent acceleratenally similar cytokines inducing NF-κB-driven proinflammatory signaling during macrophage development is a prerequisite for accelerated inflammatory responses upon IFN-γ stimulation in BS.

Glass ionomer cements (GIC) can be used to protect dentine following caries removal. However, GIC have little biological activity on biological repair processes, which means that neo-dentine formation remains reliant on limited endogenous regenerative processes. Wnt/β-catenin signalling is known to play a central role in stimulating tertiary dentine formation following tooth damage and can be stimulated by a range of glycogen synthase kinase (GSK3) antagonists, including lithium ions.

Here, we created lithium-containing bioactive glass (BG) by substituting lithium for sodium ions in 45S5 BG. We then replaced between 10 and 40% of the powder phase of a commercial GIC with the lithium-substituted BG to create a range of formulations of 'LithGlassGIC'. In vitro physical properties of the resulting glasses were characterised and their ability to stimulate reactionary dentine formation in mouse molars in vivo was tested.

Lithium release from LithGlassGIC increased with increasing lithium content in the cement. In common with unmodified commercial GIC, all formations of LithGlassGIC showed in vitro toxicity when measured using an indirect cell culture assay based on ISO109935, precluding direct pulp contact. However, in a murine non-exposed pulp model of tooth damage, LithGlassGIC quickly released lithium ions, which could be transiently detected in the saliva and blood. LithGlassGIC also enhanced the formation of tertiary dentine, resulting in a thickening of the dentine at the damage site that restored lost dentine volume. Dentine regeneration was likely mediated by upregulation of Wnt/β-catenin activity, as LithGlassGIC placed in TCF/LefH2B-GFP reporter mice showed enhanced GFP activity.

We conclude that LithGlassGIC acts as a biological restorative material that promotes tertiary dentine formation and restores tooth structure.

Clinically used bioceramics have been characterized previously with different kinds of methods and comparison of results have proven to be difficult due to varieties of the material properties of interest. Therefore, in this study we compared clinically commonly used bioceramics of hydroxyapatite and carbonate apatite, two bioactive glasses 45S5 and S53P4, and alumina with respect of properties which according to the present knowledge are significant for bone biology.

Physicochemical properties of the materials were characterized by various methods. Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) was used to analyze the material vibrational features. X-ray Power Diffraction (XRD) was used to characterize the material crystal structure and scanning electron microscopy-energy-dispersive x-ray analysis (SEM-EDXA) was used to evaluate the morphology and size of the materials and to calculate their oxide content. Dihexa The dissolution behavior of the materials, ion release and pH changes in Tris buffer in a continuous flow-through reaction for 24-hours were determined.
