    The rational use and management of energy is considered a key societal and technological challenge. Home energy management systems (HEMS) have been introduced especially in private home domains to support users in managing and controlling energy consuming devices. Recent studies have shown that informing users about their habits with appliances as well as their usage pattern can help to achieve energy reduction in private households. This requires instruments able to monitor energy consumption at fine grain level and provide this information to consumers. While the most existing approaches for load disaggregation and classification require high-frequency monitoring data, in this paper we propose an approach that exploits low-frequency monitoring data gathered by meters (i.e., Smart Plugs) displaced in the home. Moreover, while the most existing works dealing with appliance classification delegate the classification task to a remote central server, we propose a distributed approach where data processing and appliance recognition are performed locally in the Home Gateway. Our approach is based on a distributed load monitoring system made of Smart Plugs attached to devices and connected to a Home Gateway via the ZigBee protocol. The Home Gateway is based on the OSGi platform, collects data from home devices, and hosts both data processing and user interaction logic

    L\u2019Aquila, 6 aprile 2009: la gestione dell\u2019emergenza, la promozione della coesione e della salute sociale

    Il presente lavoro nasce nell\u2019ambito del Progetto Vela, che si pone come obiettivo generale "la promozione della salute\u201d in comunit\ue0 colpite da emergenza sia naturale che umanitaria. Il Progetto \ue8 un\u2019iniziativa elaborata da un gruppo di ricercato- ri afferenti all\u2019Universit\ue0 degli Studi di Padova (dipartimento FISPPA \u2013 Filosofia, Sociologia, Pedagogia e Psicologia Applicata), nato nell\u2019ottobre 2011 con l\u2019obietti- vo di indagare quali siano state le ricadute negli assetti interattivi della comunit\ue0 aquilana, ossia come essa configuri la propria realt\ue0 sociale, in seguito al sisma del 6 aprile 2009. L\u2019incipit dell\u2019articolo consiste in una riflessione teorico-conoscitiva sulla relazione tra \u201ccatastrofe\u201d, \u201csalute\u201d ed \u201cemergenza\u201d, che ha porta-to ad assumere la rilevanza di indagarli per come sono configurati dai membri della comunit\ue0, anzich\ue9 considerarli entit\ue0 statiche di per s\ue9. Coerentemente con questi assunti, attraverso appositi protocolli di indagine, sono state indagate le modalit\ue0 discorsive che configurano la "salute" del territorio aquilano prima del sisma, nelle ore di urgenza del post-sisma, allo stato attuale e in proiezione futura. I protocolli sono stati somministrati a diversi ruoli (cittadini, commercianti, insegnanti, forze dell\u2019ordine, operatori della protezione civile, medici e psicologi), in modo da raccogliere il testo di tutte le voci della comunit\ue0 aquilana. Quanto emerso ha mostrato che gli aquilani tuttora configurano la loro comunit\ue0 come "catastrofica" e dunque associata all\u2019evento sismico; dunque quest\u2019ultimo ha pervaso, e pervade, la biografia della comunit\ue0 aquilana (sia in prospettiva passata, che presente, che futura) con alto tasso di potenziale disgregazione sociale

    Spirituality for Late Adolescents Coping with Grief and Loss

    Get PDF
    Experiencing the death of a loved one is often life changing, and learning ways to cope is an important part of the healing process. Such a change can be particularly difficult for late adolescents (individuals between 18 and 25 years of age) who are already going through significant life changes. Spirituality and mental health has received increasing scholarly attention in recent years, and the Association for Spirituality, Ethics, and Religious Values in Counseling has developed competencies for counselors to use when working with clients who wish to incorporate spirituality in their treatment. Despite increased interest in the field, there is little scholarly literature on the use of spirituality in counseling late adolescents who are experiencing grief and loss. The purpose of this hermeneutic phenomenological study was to explore the meaning and role of spirituality and spiritual practices in the grieving processes of late adolescents. Existential theory provided the framework for the study. Participants were recruited from a local grief center, college, and university as well as CESnet and ASERVIC listservs. Seven late adolescents took part in semistructured interviews regarding their grieving process. Lindseth and Norberg\u27s phenomenological hermeneutical method was used to analyze the data consisting of naïve reading, structural analysis, and comprehensive understanding. Themes included experiences with death, surviving the loss, and changes. Findings indicated that spiritual practices were beneficial in helping grieving late adolescents cope with the death of a loved one. Results may provide counselors with additional ways to work with this population during their grieving process

    Antimicrobial activity of four essential oils against pigmenting Pseudomonas fluorescens and biofilm-producing Staphylococcus aureus of dairy origin

    Essential oils (EOs) are mixtures of secondary metabolites of plant origin with many useful properties, among which the antimicrobial activity is also of interest for the food industry. EOs can exert their antimicrobial potential both directly, in food products and active packaging, and indirectly, as sanitizing and anti-biofilm agents of food facility surfaces. Aim of this research was to evaluate the antimicrobial activity of four EOs (bergamot, cinnamon, manuka and thyme) against Pseudomonas fluorescens and Staphylococcus aureus isolated from mik and dairy products. The chemical composition of EOs was evaluated by Gas Chromatography-Mass Spectrometry analysis. Minimum Inhibitory Concentration values were determined by a microplate method against 9 Ps. fluorescens from marketed mozzarella with blue discoloration defect, and 3 biofilm-producing S. aureus from milk. Reference ATCC strains were included. Pigment production activity by Ps. fluorescens was assessed both in culture and in cheese. EOs of manuka (leptospermone 23%) and thyme (carvacrol 30%, p-cymene 20%, thymol 15%) showed the highest antimicrobial activity against S. aureus, MIC values were 0.012%-0.024% and 0.024% v/v, respectively; meanwhile EOs from thyme and cinnamon (cinnamaldheyde 55%) exhibited the best activity against Ps. fluorescens with MIC values of 0.098%-0.195% and 0.195%-0.391% v/v, respectively. The antimicrobial activity of these EOs is promising and they coul be exploited in the dairy production chain

    Granulocytic myeloid-derived suppressor cells increased in early phases of primary HIV infection depending on TRAIL plasma level

    Background It has been demonstrated that Myeloid Derived Suppressor Cells (MDSC) are expanded in HIV-1 infected individuals and correlated with disease progression. The phase of HIV infection during which MDSC expansion occurs, and the mechanisms that regulate this expansion remain to be established. In this study we evaluated the frequency of MDSC in patients during primary HIV infection, and factors involved in MDSC control. Methods Patients with primary (PHI) and chronic (CHI) HIV infection were enrolled. PHI staging was performed according to Fiebig classification, and circulating MDSC frequency and function were evaluated by flow cytometry. Cytokine levels were evaluated by Luminex technology. Results We found that granulocytic MDSC (Gr-MDSC) frequency was higher in PHI compared to healthy donors, but lower than CHI. Interestingly, Gr-MDSC expansion was observed in the early phases of HIV infection (Fiebig II/III), but it was not associated to HIV viral load and CD4 T cell count. Interestingly, in PHI Gr-MDSC frequency was inversely correlated with plasmatic level of TRAIL, while a direct correlation was observed in CHI. Further, lower level of GMCSF was observed in PHI compared with CHI. In vitro experiments demonstrated that, differently from CHI, recombinant TRAIL induced apoptosis of Gr-MDSC from PHI, can effect that can be abrogated by GM-CSF. Conclusion We found that Gr-MDSC are expanded early during primary HIV infection and may be regulated by TRAIL and GM-CSF levels. These findings shed light on the fine mechanisms regulating the immune system during HIV infection, and open new perspectives for immune-based strategies

    Updated incidence data of acute Delta virus hepatitis (HDV) are lacking worldwide. Our aim was to evaluate incidence of and risk factors for acute HDV in Italy after the introduction of the compulsory vaccination against hepatitis B virus (HBV) in 1991. Data were obtained from the National Surveillance System of acute viral hepatitis (SEIEVA). Independent predictors of HDV were assessed by logistic-regression analysis. The incidence of acute HDV per 1-million population declined from 3.2 cases in 1987 to 0.04 in 2019, parallel to that of acute HBV per 100,000 from 10.0 to 0.39 cases during the same period. The median age of cases increased from 27 years in the decade 1991-1999 to 44 years in the decade 2010-2019 (p < .001). Over the same period, the male/female ratio decreased from 3.8 to 2.1, the proportion of coinfections increased from 55% to 75% (p = .003) and that of HBsAg positive acute hepatitis tested for by IgM anti-HDV linearly decreased from 50.1% to 34.1% (p < .001). People born abroad accounted for 24.6% of cases in 2004-2010 and 32.1% in 2011-2019. In the period 2010-2019, risky sexual behaviour (O.R. 4.2; 95%CI: 1.4-12.8) was the sole independent predictor of acute HDV; conversely intravenous drug use was no longer associated (O.R. 1.25; 95%CI: 0.15-10.22) with this. In conclusion, HBV vaccination was an effective measure to control acute HDV. Intravenous drug use is no longer an efficient mode of HDV spread. Testing for IgM-anti HDV is a grey area requiring alert. Acute HDV in foreigners should be monitored in the years to come

    Host genetics and COVID-19 severity: increasing the accuracy of latest severity scores by Boolean quantum features

    Get PDF
    The impact of common and rare variants in COVID-19 host genetics has been widely studied. In particular, in Fallerini et al. (Human genetics, 2022, 141, 147–173), common and rare variants were used to define an interpretable machine learning model for predicting COVID-19 severity. First, variants were converted into sets of Boolean features, depending on the absence or the presence of variants in each gene. An ensemble of LASSO logistic regression models was used to identify the most informative Boolean features with respect to the genetic bases of severity. After that, the Boolean features, selected by these logistic models, were combined into an Integrated PolyGenic Score (IPGS), which offers a very simple description of the contribution of host genetics in COVID-19 severity.. IPGS leads to an accuracy of 55%–60% on different cohorts, and, after a logistic regression with both IPGS and age as inputs, it leads to an accuracy of 75%. The goal of this paper is to improve the previous results, using not only the most informative Boolean features with respect to the genetic bases of severity but also the information on host organs involved in the disease. In this study, we generalize the IPGS adding a statistical weight for each organ, through the transformation of Boolean features into “Boolean quantum features,” inspired by quantum mechanics. The organ coefficients were set via the application of the genetic algorithm PyGAD, and, after that, we defined two new integrated polygenic scores (IPGSph1 and IPGSph2). By applying a logistic regression with both IPGS, (IPGSph2 (or indifferently IPGSph1) and age as inputs, we reached an accuracy of 84%–86%, thus improving the results previously shown in Fallerini et al. (Human genetics, 2022, 141, 147–173) by a factor of 10%

    Rischio cardiovascolare e alterazioni metaboliche nell'iperaldosteronismo primario: valutazione clinica e potenziale ruolo patogenetico del tessuto adiposo

    No full text
    L’iperaldosteronismo primario (PA) è una patologia caratterizzata da ipertensione arteriosa e da una serie di complicanze che coinvolgono cuore, vasi, rene e metabolismo. I meccanismi patogenetici che sottendono la relazione tra PA e lo sviluppo delle sue complicanze non sono ancora noti e il tessuto adiposo potrebbe avere un ruolo chiave. Lo scopo del lavoro è stato: 1) valutare il rischio cardiovascolare (CVR) secondo le Linee Guida ESH-ESC su 102 pazienti affetti da PA alla diagnosi e dopo terapia, confrontandolo con 132 ipertesi essenziali (EH) di pari età, sesso e durata di malattia; 2) studiare l’espressione di geni coinvolti nel metabolismo glico-lipidico e nell’infiammazione nel tessuto adiposo omentale di pazienti con adenoma aldosterone secernente (APA) sottoposti a surrenectomia. Per lo studio clinico, oltre al grado di ipertensione, abbiamo valutato l’assetto lipidico, la glicemia a digiuno e dopo carico, la circonferenza vita, la funzionalità renale, la familiarità, il fumo, le comordità ed eseguito ecocardiogramma e ecodoppler vasi epiaortici. Per lo studio molecolare abbiamo effettuato un'analisi microarray seguita poi da real time-PCR su adipe di 16 pazienti con APA e di 10 pazienti con adenoma surrenalico noniperfunzionante, per quantificare l’espressione di alcuni geni selezionati (esochinasi 1, IL-1R1, IL- 6, colesterolo-25-idrossilasi, lipoprotein lipasi, omentina, visfatina). Il CVR è risultato essere più elevato nei PA rispetto agli EH per la presenza di più elevati valori pressori, maggiore prevalenza di iperglicemia, sindrome metabolica, abitudine tabagica e ipertrofia ventricolare sinistra. Dopo terapia, il CVR si è ridotto in entrambe le popolazioni ed è diventato sovrapponibile tra PA ed EH, nonostante i PA presentassero valori di pressione arteriosa più alti, grazie ad una riduzione di alcuni fattori di rischio ed una parziale regressione del danno d’organo. E’ stata inoltre rilevata un’aumentata espressione del gene dell’interleuchina 6, una citochina proinfiammatoria coinvolta nello sviluppo di insulino-resistenza e di patologie vascolari, a livello del tessuto adiposo omentale di pazienti con APA, che potrebbe, almeno in parte, contribuire alla patogenesi della sindrome cardiometabolica e all’elevato rischio cardiovascolare che caratterizza questi soggetti
