REVERSE MODELLING PROCESS TO SUPPORT OF A FLEMISH WOODEN ALTARPIECE PHYSICAL RESTORATION

This study focuses on digital Computer Aided Restoration procedures to guide the complex physical restoration of an artwork, innovating and implementing traditional survey methods. As a case study some results are presented of a complex and articulated conservative restoration project on a sculpted and painted wing altar, preserved in the Regional Gallery of Sicily in Palazzo Abatellis, Palermo. The application of non-invasive and high information density 3D survey methodologies allowed to record and integrate into a unique digital platform (designed within the UnReal Engine) a wide quantity of heterogeneous data which document the work's state (diagnostic analyses, graphical annotation, historical information). The multidisciplinary investigation process is aimed to guide the disassembly of the various components, to tell the long process of activity in the laboratory and to experiment the realization and integration of missing parts. The innovative application of 3D digital technologies shows how the integrated use of the new technology can be a useful tool for improving the conservation of a work of art. The data processed have permitted a better interpretative reading, implementing the knowledge of the scholars, and a more effective communication and fruition to the audience

Epidemiology of enuresis: a large number of children at risk of low regard

Aim: To describe the epidemiological aspects of nocturnal enuresis (NE). In this study we identify the prevalence and the familial conditions in a large, representative sample of children with monosymptomatic NE (MNE) and nonmonosyptomatic NE (NMNE). Material and methods: In this descriptive-analytic study the Italian Society of Pediatrics (SIP) promoted a prevalence study of NE using a questionnaire involved 320 primary care Pediatricians from Northern, Central and Southern Italy, from January 2019 to July 2019, with a total of 130,000 children analyzed by questionnaire related to epidemiology and type of NE, familiarity, quality of sleep, eating and drinking habits, pharmacological and psychological/behavioural interventions and family involvement. Results: 270/320 (84.4%) Paediatrician replied to our questionnaire. We enrolled a total of 9307/130,000 (7.2%) children with NE, aged between 5 and 14 years: 2141 diagnosed with MNE and 7176 qualified as NMNE. Poor quality of sleep were reported in 7064 patients; 90% of children did not consider a dietary and drinking recommendation. Pediatrician reported a total of 54.1% of parents who declared to have a negative reaction to their children because of the bedwetting. A percentage of 71.4% of parents declared to use or to have used alternative therapies and not to prefer, at first, a pharmacological intervention. Conclusion: The choice of treatment should include psychological/behavioural interventions in all cases to improve the therapeutic outcome. All primary care Pediatricians should be aware of the all aspects of NE to choose the best way to treat every patient

Impact of COVID-19 pandemic on 2-[18F]FDG PET/CT imaging work-flow in a single medical institution: comparison among the three Italian waves

Purpose: To compare the impact of COVID-19 pandemic on 2-[18F]FDG PET/CT imaging work-flow during the three waves in a medical institution of southern of Italy. Methods: We retrospectively reviewed the numbers and results of 2-[18F]FDG PET/CT studies acquired during the following three periods of the COVID-19 waves: 1) February 3-April 30, 2020; 2) October 15, 2020–January 15, 2021; and 3) January 18-April 16, 2021. Results: A total of 861 PET/CT studies in 725 patients (388 men, mean age 64 +/- 4 years) was acquired during the three waves of COVID-19 pandemic. The majority (94%) was performed for diagnosis/staging (n = 300) or follow-up (n = 512) of neoplastic diseases. The remaining 49 studies (6%) were acquired for non-oncological patients. The distribution of number and type of clinical indications for PET/CT studies in the three waves were comparable (p < 0.06). Conversely, the occurrence of patients positive for COVID-19 infection progressively increased (p < 0.0001) from the first to third wave; in particular, patients with COVID-19 had active infection before PET/CT study as confirmed by molecular oro/nasopharyngeal swab. Conclusion: Despite the restrictive medical measures for the emergency, the number of 2-[18F]FDG PET/CT studies was unchanged during the three waves guaranteeing the diagnostic performance of PET/CT imaging for oncological patients

Immunometabolic interference between cancer and COVID-19

Even though cancer patients are generally considered more susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, the mechanisms driving their predisposition to severe forms of coronavirus disease 2019 (COVID-19) have not yet been deciphered. Since metabolic disorders are associated with homeostatic frailty, which increases the risk of infection and cancer, we asked whether we could identify immunometabolic pathways intersecting with cancer and SARS-CoV-2 infection. Thanks to a combined flow cytometry and multiomics approach, here we show that the immunometabolic traits of COVID-19 cancer patients encompass alterations in the frequency and activation status of circulating myeloid and lymphoid subsets, and that these changes are associated with i) depletion of tryptophan and its related neuromediator tryptamine, ii) accumulation of immunosuppressive tryptophan metabolites (i.e., kynurenines), and iii) low nicotinamide adenine dinucleotide (NAD+) availability. This metabolic imbalance is accompanied by altered expression of inflammatory cytokines in peripheral blood mononuclear cells (PBMCs), with a distinctive downregulation of IL-6 and upregulation of IFNγ mRNA expression levels. Altogether, our findings indicate that cancer not only attenuates the inflammatory state in COVID-19 patients but also contributes to weakening their precarious metabolic state by interfering with NAD+-dependent immune homeostasis
