    Abstract Background: Epigenetic mechanisms, including DNA methylation, histone modifications, and chromatin remodeling, are highly involved in the regulation of hepatocyte viability, proliferation, and plasticity. We have previously demonstrated that repression of H3K27 methylation in differentiated hepatic HepaRG cells by treatment with GSK-J4, an inhibitor of JMJD3 and UTX H3K27 demethylase activity, changed their phenotype, inducing differentiated hepatocytes to proliferate. In addition to the epigenetic enzymatic role in the regulation of the retro-differentiation process, emerging evidence indicate that microRNAs (miRNAs) are involved in controlling hepatocyte proliferation during liver regeneration. Hence, the aim of this work is to investigate the impact of H3K27 methylation on miRNAs expression profile and its role in the regulation of the differentiation status of human hepatic progenitors HepaRG cells.
    Methods: A miRNA-sequencing was carried out in differentiated HepaRG cells treated or not with GSK-J4. Target searching and Gene Ontology analysis were performed to identify the molecular processes modulated by differentially expressed miRNAs. The biological functions of selected miRNAs was further investigated by transfection of miRNAs inhibitors or mimics in differentiated HepaRG cells followed by qPCR analysis, albumin ELISA assay, CD49a FACS analysis and EdU staining.
    Results: We identified 12 miRNAs modulated by GSK-J4; among these, miR-27a-3p and miR- 423-5p influenced the expression of several proliferation genes in differentiated HepaRG cells. MiR-27a-3p overexpression increased the number of hepatic cells reentering proliferation. Interestingly, both miR-27a-3p and miR-423-5p did not affect the expression levels of genes involved in the differentiation of progenitors HepaRG cells.
    Conclusions: Modulation of H3K27me3 methylation in differentiated HepaRG cells, by GSK-J4 treatment, influenced miRNA' s expression profile pushing liver cells towards a proliferating phenotype. We demonstrated the involvement of miR-27a-3p in reinducing proliferation of differentiated hepatocytes suggesting a potential role in liver plasticity.

    Abstract Patient suicide is one of the most frequent incidents in healthcare facilities to be reported to the National Observatory of Sentinel Events in Italy. Despite national initiatives, in Tuscany potentially preventable patient suicides still occur in both acute and community care settings. We describe here an aggregated qualitative analysis of 14 patient suicides that took place in public health services between 2017 and 2018. We outline the methodology and results of an improvement action we enacted in the healthcare system that involved reviewing and reinforcing relevant managerial strategies and clinical activities, with the aim of reducing potentially preventable patient suicides.

    Abstract Study design: An observational study based on an online survey to explore if the participant had experienced (1) cancellation or delay of scheduled health services (2) reduction of assistance provided by a caregiver (3) barriers to social participation and recreational activities. Three validated questionnaires to investigate well-being and symptoms of anxiety and depression were also administered.
    Objectives: Our main aim was to quantify the obstacles experienced by adults living with SCI in Italy during COVID-19 pandemic, to explore the presence of depression and anxiety symptoms and to quantify subjective well-being.
    Setting: Outpatient clinic of a Spinal Unit in Italy.
    Methods: Online survey via direct contact and by e-mail lists.
    Results: In total, 101 individuals completed the survey. Of, 82.2% participants reported a history of deferment or cancellation of non-COVID-19 health services. The majority (56.4%) revealed that, at least seldom, they have chosen to reduce their usual everyday activities and more than one third (37.6%) affirmed that they had been forced to renounce to one or more of their occupations. Discontinuation of assistance by caregivers was uncommon. The median score of questionnaires measuring depression and anxiety symptoms do not differ significatively when compared with prior studies. The variable that explored the limitations experienced in everyday activities showed a significant correlation with the results of the questionnaires measuring well-being and symptoms of anxiety.
    Conclusions: We believe that our results could contribute to the discussion ongoing inside our community on how to answer to the new challenges of this pandemic period and of the post-pandemic future.

    Abstract Background: Lymph node metastasis in oral squamous cell carcinoma (OSCC) is associated with poor prognosis. The 8th edition of TNM has implemented new nodal staging criteria. We assess the prognostic utility of the lymph node ratio (LNR) and compare it to that of pN in the TNM 8th edition.
    Methods: One hundred and forty-two patients with OSCC were retrospectively studied. Nodal staging was performed using the TMN 8th edition and the prognostic value of the LNR in terms of overall survival (OS) and disease-free survival (DFS) was evaluated.
    Results: Fifty-seven patients were eligible for inclusion. The LNR was independently prognostic of OS (p = 0.02). Instead N classification was not significantly predictive of OS (p = 0.10). High LNRs resulted in decreases in OS of approximately 40% within 6 months after surgery.
    Conclusions: The LNR identifies patients with poor outcomes better than N classification. The lack of reliable LNR cutoffs compromises its utility in clinical practice.

    Abstract Background: Subjective Cognitive Decline (SCD) is a self-experienced decline in cognitive capacity with normal performance on standardized cognitive tests, showing to increase risk of Alzheimer's Disease (AD). Cognitive reserve seems to influence the progression from SCD to Mild Cognitive Impairment (MCI) and to AD. The aim of our study was to investigate gender differences in cognitive reserve evaluating how sex might modulate the role of cognitive reserve on SCD.
    Methods: We included 381 SCD patients who underwent clinical evaluation, neuropsychological assessment, evaluation of premorbid intelligence by the Test di Intelligenza Breve (TIB), cognitive complaints by the Memory Assessment Clinics Questionnaire (MAC-Q), and apolipoprotein E (APOE) genotyping.
    Results: The proportion between women and men was significantly different (68.7% [95% CI 63.9-73.4 vs 31.4%, 95% CI 26.6-36.0]). Women were younger than men at onset of SCD and at the baseline visit (p = 0.021), had lower years of education (p = 0.007), lower TIB scores (p < 0.001), and higher MAC-Q scores (p = 0.012). TIB was directly associated with age at onset of SCD in both women and men, while years of education was inversely associated with age at onset only in women. Multivariate analysis showed that sex influences TIB independently from years of education. TIB was directly associated with MAC-Q in men.
    Conclusions: Sex interacts with premorbid intelligence and education level in influencing the age at onset and the severity of SCD. As the effect of education was different between men and women, we speculated that education might act as a minor contributor of cognitive reserve in women.

    Abstract Background: An increased risk of contracting HIV infection, suboptimal adherence, and a loss to follow-up have been observed in migrants, particularly if those individuals are transgender or sex workers. A clear picture of the HIV epidemic among migrants is complex due to the lack of specific national data.
    Aims: We developed a qualitative study that describes the barriers and facilitators (cultural, social, and personal) in HIV testing and the continuum of care for a group of migrant transgender women who are sex workers.
    Methods: A semi-structured interview was conducted with a group of migrant transgender women who are sex workers living with HIV or with unknown HIV serostatus residing in the Florentine metropolitan area.
    Results: We included 12 participants: 3 had unknown HIV serostatus and 9 were living with HIV in follow-up at the Clinic of Infectious and Tropical Diseases, Careggi University hospiral, Florence, Italy. Among barriers, the perceived stigma due to their identity as migrants and transgender people, the language lack of ability and the legal position in the host country played a significant role. Moreover, the interviewees claimed having no alternative to sex work: for those individuals, changing their lifestyle condition is perceived as difficult or impossible due to social prejudices. Conversely, the interviewees considered support services, such as cultural mediators/interpreters and street units, as facilitators to HIV testing, access to care, and continuum of care. Having regular and accessible ART and the availability of a more consistent health care system, represent reasons for HIV-positive migrants living with HIV to move to Italy.
    Conclusions: Knowledge of this population's personal experience regarding the barriers and factors that facilitate access to the HIV care system is essential for planning public health interventions capable of responding to the real needs of patients.

    Abstract Hepatic steatosis represents a metabolic dysfunction that results from an accumulation of triglyceride-containing lipid droplets in hepatocytes. Excessive fat accumulation leads to non-alcoholic fatty liver disease (NAFLD), which is potentially reversible and may evolve into non-alcoholic steatohepatitis (NASH) and eventually cirrhosis and hepatocellular carcinoma (HCC). The molecular mechanisms linking lipid accumulation in hepatocytes with the progression to NASH, irreversible liver damage, fibrosis, cirrhosis, and even HCC still remains unclear. To this end, several in vitro and in vivo models have been developed to elucidate the pathological processes that cause NAFLD. In the present study, we describe a cellular model for the induction of liver vesicular steatosis that consists of DMSO-differentiated human hepatic HepaRG cells treated with the fatty acid salt sodium oleate. Indeed, sodium oleate-treated HepaRG cells accumulate lipid droplets in the cytoplasm and show typical features of steatosis. This in vitro human model represents a valuable alternative to in vivo mice models as well as to the primary human hepatocytes. We also present a comparison of several methods for the quantification and evaluation of fat accumulation in HepaRG cells, including Oil Red O staining, cytofluorimetric Bodipy measurement, metabolic gene expression analysis by qPCR, and coherent anti-Stokes Raman scattering (CARS) microscopy. CARS imaging combines the chemical specificity of Raman spectroscopy, a chemical analysis technique well-known in materials science applications, with the benefits of high-speed, high-resolution non-linear optical microscopies to allow precise quantification of lipid accumulation and lipid droplet dynamics. The establishment of an efficient in vitro model for the induction of vesicular steatosis, alongside an accurate method for the quantification and characterization of lipid accumulation, could lead to the development of early stage diagnosis of NAFLD via the identification of molecular markers, and to the generation of new treatment strategies.
