Life during COVID-19 lockdown in Italy: the influence of cognitive state on psychosocial, behavioral and lifestyle profiles of older adults.

Few studies have examined lockdown effects on the way of living and well-being of older adults stratified by cognitive state. Since cognitive deficits are common in this population, we investigated how cognition influenced their understanding of the pandemic, socio-behavioral responses and lifestyle adaptations during lockdown, and how these factors affected their mood or memory.Telephone-based survey involving 204 older adults ≥65 y/o (median: 82) with previous assessments of cognitive state: 164 normal-old (NOLD), 24 mild-neurocognitive disorder (mild-NCD), 18 mild-moderate dementia. A structured questionnaire was developed to assess psychological and socio-behavioral variables. Logistic regression was used to ascertain their effects on mood and memory.With increasing cognitive deficits, understanding of the pandemic and the ability to follow lockdown policies, adapt to lifestyle changes, and maintain remote interactions decreased. Participants with dementia were more depressed; NOLDs remained physically and mentally active but were more bored and anxious. Sleeping and health problems independently increased the likelihood of depression (OR: 2.29; CI: 1.06-4.93;NOLD and mild-NCD groups showed similar mood-behavioral profiles suggesting better tolerance of lockdown. Those with dementia were unable to adapt and suffered from depression and cognitive complaints. To counteract lockdown effects, physical and mental activities and digital literacy should be encouraged

La sinistra:italiana una commedia in tre atti.

L’entrata nella seconda Repubblica è stata scandita dalla marcia trionfale della sinistra in predicato di vincere le elezioni politiche. I risultati elettorali più gratificanti della sinistra sono stati la traballante vittoria del 1996 e le non vittorie (sostanziali pareggi) del 2006 e del 2013, al contrario erano certe nelle previsioni e nei fatti le vittorie berlusconiane del 2001 e del 2008

Balancing efficacy and tolerability of first-line systemic therapies for advanced hepatocellular carcinoma: a network metanalysis

Background: Atezolizumab+Bevacizumab represents the current standard of care for first-line treatment of advanced HCC. However, direct comparison with other combination treatments including immune-checkpoint inhibitors(ICI)+tyrosine-kinase inhibitors(TKIs) are lacking. Objectives: This network meta-analysis(NMA) aims to indirectly compare the efficacy and the safety of first-line systemic therapies for unresectable-advanced HCC. Method:A literature search of MEDLINE, EMBASE and SCOPUS databases was conducted up to 31st October, 2022. Phase III randomized controlled trials(RCTs) testing TKIs, including Sorafenib and Lenvatinib, or ICIs reporting overall survival(OS) and progression-free survival(PFS) were included. Individual survival data were extracted from OS and PFS curves to calculate restricted mean survival time (RMST). A Bayesian NMA was performed to compare treatments in terms of efficacy(15- and 30-month OS, 6-month PFS) and safety, represented by grade≥3(severe)adverse events(SAEs). The incremental safety-effectiveness ratio(ISER) as measure of net health benefit was calculated as the difference in SAEs probability divided by survival difference between the 2 most effective treatments. Results:Nine RCTs enrolling 6600 patients were included. Atezolizumab plus bevacizumab showed the highest probability(88%)of achieving the 30-month OS landmark. Lenvatinib showed a probability of 86% of achieving best PFS outcomes. ICI monotherapies ranked as most tolerable. Atezolizumab plus Bevacizumab showed the best net health benefit for OS, compared to Durvalumab plus Tremelimumab. When evaluating the net health benefit for PFS, at a willingness-to-risk threshold of 10% of SAEs for life-month gained, Atezolizumab plus Bevacizumab was favored in 78% of cases, while at threshold of 30% of SAEs for life-month gained, Lenvatinib was favored in 76% of cases. Conclusions: Atezolizumab plus Bevacizumab is the best treatment in terms of net benefit and therefore it should be recommended as standard of care. Compared to Atezolizumab plus Bevacizumab, Lenvatinib monotherapy had the best net benefit for PFS when physicians and patients are available to accept a higher risk of toxicity

Multicentre Italian study of SARS-CoV-2 infection in children and adolescents, preliminary data as at 10 April 2020

Data on features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children and adolescents are scarce. We report preliminary results of an Italian multicentre study comprising 168 laboratory-confirmed paediatric cases (median: 2.3 years, range: 1 day-17.7 years, 55.9% males), of which 67.9% were hospitalised and 19.6% had comorbidities. Fever was the most common symptom, gastrointestinal manifestations were frequent; two children required intensive care, five had seizures, 49 received experimental treatments and all recovered

OltreMare - Un progetto per il futuro della Biodiversità del Mediterraneo

Osservatorio e comunicazione. Questo progetto narra dello sguardo degli artisti dell’Accademia di Belle Arti di Palermo sul lavoro di ricerca portato avanti dall’IAS - CNR (ex IAMC) riguardo all’osservazione e alla tutela della Biodiversità e costituisce uno strumento eccellente di comunicazione per un pubblico quanto mai ampio. La divulgazione della scienza è un’attività complessa e sicuramente necessita di competenze e attitudini multidisciplinari oltreché di motivazione ed entusiasmo. La comunicazione delle tematiche scientifiche, di per sè ostiche nella traduzione al grande pubblico, grazie alla forza e all’immediatezza tipica dell’espressione artistica diventa prodigioso spunto di riflessione e di osservazione, sia per i giovani che per la comunità intera. Grazie al progetto Osservatorio della Biodiversità Siciliana, sono state realizzate da partners con competenze istituzionali complementari , quali l’Accademia di Belle Arti di Palermo e l’IAS - CNR di Capo Granitola, delle azioni didattiche e creative di valore scientifico espresse con straordinaria forza e bellezza. La sinergia creata, nata da un rapporto consolidato ormai da tempo, ha portato ad uno scambio tra ricercatori e professori che si sono messi in gioco in uno sforzo congiunto per avvicinare le proprie competenze. In seguito ad un’intensa attività di coordinamento e pianificazione dei lavori, si è riusciti a portare avanti un progetto ambizioso e imponente, coinvolgendo moltissimi ambiti scientifici e altrettante cattedre, sensibilizzando così gli artisti ai temi della Biodiversità. Le opere prodotte, accompagnate da schede scientifiche, hanno dunque acquisito un valore, oltreché artistico, didattico, e restano come testimonianze oggettive, nel percorso culturale, per i visitatori dell’Osservatorio. Questa collaborazione conferma l’importanza e l’opportunità di unire arte e scienza per esaltare la percezione della ricerca scientifica da parte della comunità e ,ancora una volta, si conferma come, per fare “cose straordinarie”, siano più importanti i rapporti umani piuttosto che le competenze tecniche. A tal proposito, un ringraziamento sentito al Prof. Calogero Piro che, con passione e dedizione, ha reso possibile questa esperienza, e al gruppo di Comunicazione EDU Lab dell’IAS - CNR, che è stato, per me, un supporto indispensabile per la realizzazione di questo complesso progetto

The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase

The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile observatory designed to address the Hot and Energetic Universe science theme, selected in November 2013 by the Survey Science Committee. Based on a large format array of Transition Edge Sensors (TES), it aims to provide spatially resolved X-ray spectroscopy, with a spectral resolution of 2.5 eV (up to 7 keV) over an hexagonal field of view of 5 arc minutes (equivalent diameter). The X-IFU entered its System Requirement Review (SRR) in June 2022, at about the same time when ESA called for an overall X-IFU redesign (including the X-IFU cryostat and the cooling chain), due to an unanticipated cost overrun of Athena. In this paper, after illustrating the breakthrough capabilities of the X-IFU, we describe the instrument as presented at its SRR, browsing through all the subsystems and associated requirements. We then show the instrument budgets, with a particular emphasis on the anticipated budgets of some of its key performance parameters. Finally we briefly discuss on the ongoing key technology demonstration activities, the calibration and the activities foreseen in the X-IFU Instrument Science Center, and touch on communication and outreach activities, the consortium organisation, and finally on the life cycle assessment of X-IFU aiming at minimising the environmental footprint, associated with the development of the instrument. Thanks to the studies conducted so far on X-IFU, it is expected that along the design-to-cost exercise requested by ESA, the X-IFU will maintain flagship capabilities in spatially resolved high resolution X-ray spectroscopy, enabling most of the original X-IFU related scientific objectives of the Athena mission to be retained.

We then show the instrument budgets, with a particular emphasis on the anticipated budgets of some of its key performance parameters, such as the instrument efficiency, spectral resolution, energy scale knowledge, count rate capability, non X-ray background and target of opportunity efficiency. Finally, we briefly discuss the ongoing key technology demonstration activities, the calibration and the activities foreseen in the X-IFU Instrument Science Center, touch on communication and outreach activities, the consortium organisation and the life cycle assessment of X-IFU aiming at minimising the environmental footprint, associated with the development of the instrument.

The X-IFU will be provided by an international consortium led by France, The Netherlands and Italy, with ESA member state contributions from Belgium, Czech Republic, Finland, Germany, Poland, Spain, Switzerland, with additional contributions from the United States and Japan.The French contribution to X-IFU is funded by CNES, CNRS and CEA.

Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. For example, a key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process versus those that measure fl ux through the autophagy pathway (i.e., the complete process including the amount and rate of cargo sequestered and degraded). In particular, a block in macroautophagy that results in autophagosome accumulation must be differentiated from stimuli that increase autophagic activity, defi ned as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (inmost higher eukaryotes and some protists such as Dictyostelium ) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the fi eld understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. It is worth emphasizing here that lysosomal digestion is a stage of autophagy and evaluating its competence is a crucial part of the evaluation of autophagic flux, or complete autophagy. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. Along these lines, because of the potential for pleiotropic effects due to blocking autophagy through genetic manipulation it is imperative to delete or knock down more than one autophagy-related gene. In addition, some individual Atg proteins, or groups of proteins, are involved in other cellular pathways so not all Atg proteins can be used as a specific marker for an autophagic process. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field

Visita all'Osservatorio della Biodiversità marina e terrestre della Regione Sicilia - ORBS

Con il taglio inaugurale del nastro il 16 dicembre 2015, prende vita la struttura museale permanente dell'Osservatorio della Biodiversità marina e terrestre della Regione Sicilia che porta lo stesso nome del Progetto di Ricerca "ORBS – Sistema di comunicazione, informazione e diffusione dell'Osservatorio Regionale della Sicilia", intitolata il 21 dicembre 2018 al Dott. Sandro Fiorelli. Ad oggi, la struttura, è operativa presso la Sede Secondaria dell'Istituto per lo studio degli impatti Antropici e Sostenibilità in ambiente marino del Consiglio Nazionale delle Ricerche (IAS – CNR) di Capo Granitola. Il progetto ORBS, finanziato da Regione Siciliana - Assessorato alla Cooperazione, Commercio, Artigianato e Pesca - Dipartimento Pesca, con periodo di attività 2013 - 2015, si è concluso proprio con la realizzazione della struttura museale; l'Osservatorio è stato istituito dall'Assessorato del Territorio e dell'Ambiente della Regione Siciliana nell'ambito di un accordo quadro con ARPA, ISPRA e CNR. Grazie al progetto ORBS, docenti e allievi dell'Accademia di Belle Arti di Palermo e il personale CNR – IAS (ex IAMC) S. S. di Capo Granitola, hanno collaborato sinergicamente permettendo di realizzare delle azioni didattiche e creative di valore scientifico espresse con straordinaria forza e bellezza. Ricercatori e professori si sono confrontati al fine di combinare le proprie competenze riuscendo nel progetto ambizioso di coinvolgere e fondere i diversi ambiti scientifici sensibilizzando gli artisti ai temi della Biodiversità. Le opere prodotte, corredate da schede scientifiche, hanno oltre al valore artistico un aggiunto valore didattico. L'apertura della sezione espositiva dedicata alla diffusione e alla comunicazione della biodiversità rappresenta da un lato l'importante tappa conclusiva del progetto, dall'altro l'inizio di un percorso mirato alla diffusione della biodiversità verso il mondo giovanile, le scuole e per tutto il territorio. Questa strepitosa collaborazione "CNR – Accademia di Belle Arti di Palermo" conferma l'importanza e l'opportunità di unire arte e scienza per esaltare la percezione della ricerca scientifica da parte della comunità. La divulgazione della scienza è un'attività complessa e sicuramente necessita di competenze e attitudini multidisciplinari oltreché di motivazione ed entusiasmo. La comunicazione delle tematiche scientifiche, di per sé ardua nella traduzione al grande pubblico, grazie alla forza esplicativa dell'arte, diviene opportunità di riflessione, osservazione, confronto per le comunità di visitatori. Il coordinamento delle visite delle scuole di ogni ordine e grado, Enti Pubblici, Comunità Scientifica, Cariche Istituzionali, Delegazioni di Politici Italiani e Stranieri, Associazioni Culturali, Associazioni No-Profit di Volontariato, Associazioni di Promozione Sociale, Organizzazioni di Volontariato, Onlus, pubblico in generale, presso ORBS, è affidato al qualificato personale (tecnici, tecnologi e ricercatori) dell'IAS – CNR S. S. di Capo Granitola, che gestisce in prima persona i visitatori nel percorso didattico e promuove il valore della divulgazione scientifica perseguendo la terza missione degli Enti di Ricerca, attraverso l'applicazione diretta, la valorizzazione e l'impiego della conoscenza
