    Il presente studio è stato effettuato alfine di stimare parte della qualità ambientale in alcuni parchi della città di Roma. Per tale indagine sono stati utilizzati muschi, suoli superficiali raccolti nei parchi di Villa Borghese, Villa Ada e Villa Doria Pamphili. Queste aree sono state scelte perché adiacenti a strade ad alto traffico veicolare. Complessivamente sono state approntate 11 stazioni di prelievo. Sono state valutate le concentrazioni di metalli pesanti quali Al, Cd, Cr, Cu, Hg, Ni, Pb, V, Zn, Pt e Rh in suoli e muschi, i valori ottenuti hanno permesso di osservare l¿andamento spaziale e identificare l¿origine delle ricadute degli elementi. In aggiunta su un campione composito di suolo per ogni "villa" è stata stimata la concentrazione di IPA, PCBs e Organoclorurati. Per una indagine più approfondita sono stati altresì utilizzati indicatori microbiologici, biochimici e molecolari della qualità del suolo al fine di valutare l¿effetto delle deposizioni al suolo di inquinanti presenti nell¿aria nei confronti della popolazione microbica e dei cicli biogeochimici. L¿insieme dei dati ottenuti ha permesso di valutare parte dello stato di salute dei tre parchi romani; l¿indagine andrebbe allargata sia agli altri parchi romani sia ai parchi di altre città italiane ed estere utilizzando la stessa metodica per una comparazione dei risultati e per conoscere la qualità dei parchi cittadini al fine di una corretta gestione.

    Automatic Recognition of Prosodic Patterns in Semantic Verbal Fluency Tests - an Animal Naming Task for Edutainment Applications

    Get PDF
    This paper automatically detects prosodic patterns in the domain of semantic fluency tests. Verbal fluency tests aim at evaluating the spontaneous production of words under constrained conditions. Mostly used for assessing cognitive impairment, they can be used in a plethora of domains, as edutainment applications or games with educational purposes. This work discriminates between list effects, disfluencies, and other linguistic events in an animal naming task. Recordings from 42 Portuguese speakers were automatically recognized and AuToBI was applied in order to detect prosodic patterns, using both European Portuguese and English models. Both models allowed to differentiate list effects from the other events, mostly represented by the tunes: L* H/L(-%) (English models) or L*+H H/L(-%) (Portuguese models). However, English models proved to be more suitable because they rely in substantial more training material.info:eu-repo/semantics/publishedVersio

    Assessment of Parkinson’s disease medication state through automatic speech analysis

    Get PDF
    Parkinson’s disease (PD) is a progressive degenerative disorder of the central nervous system characterized by motor and nonmotor symptoms. As the disease progresses, patients alternate periods in which motor symptoms are mitigated due to medication intake (ON state) and periods with motor complications (OFF state). The time that patients spend in the OFF condition is currently the main parameter employed to assess pharmacological interventions and to evaluate the efficacy of different active principles. In this work, we present a system that combines automatic speech processing and deep learning techniques to classify the medication state of PD patients by leveraging personal speech-based bio-markers. We devise a speakerdependent approach and investigate the relevance of different acoustic-prosodic feature sets. Results show an accuracy of 90.54% in a test task with mixed speech and an accuracy of 95.27% in a semi-spontaneous speech task. Overall, the experimental assessment shows the potentials of this approach towards the development of reliable, remote daily monitoring and scheduling of medication intake of PD patients.info:eu-repo/semantics/publishedVersio

    Factors associated with increased suicide risk in obsessive-compulsive disorder

    Get PDF
    Objectives: Obsessive-Compulsive Disorder (OCD) is in itself at greater risk for suicide (suicidal ideation, suicide attempts and completed suicide) as compared to the general population. However, the majority of individuals with OCD do not have current or lifetime suicidal ideation nor did attempt suicide in their lifetime. Methods: The present paper aims to provide an updated review on factors (socio-demographic and personal factors, OCD-related variables, comorbidities, emotion-cognitive factors, and biological variables) contributing to the increased suicide risk in patients with OCD. Results: Several factors have been found to be strongly associated with suicide risk in patients with OCD, such as the severity of OCD, the unacceptable thoughts symptom dimension, having a comorbid Axis I disorder (Bipolar Disorder, Major Depressive Disorder, Substance Use Disorder), the severity of comorbid depressive and anxiety symptoms, a previous history of suicide attempts, having high levels of alexithymia and hopelessness. Conclusions: Several contributing factors should be evaluated and identified in the clinical practice in order to improve early detection of suicide risk. Risk identification and stratification of risk remain essential components of suicide prevention and should guide the clinical approach to patients with OCD. Whether and how these risk factors for suicide in patients with OCD work together, and whether the specific factors act as moderators or mediators, remains to be fully clarified

    Prenatal genetic counselling: issues and perspectives for pre-conceptional health care in Emilia Romagna (Northern Italy)

    Get PDF
    Background: there are many reasons why a couple may seek specialist genetic counselling about foetal risk. The referral for prenatal genetic counselling of women with a known risk factor during pregnancy has many disadvantages. Despite this, 10-20% of women seek counselling when already pregnant. Methods: data on 804 pregnant women out of 2 158 (37.3%) referred for genetic counselling in 2010 to three Clinical Genetic Services were retrospectively analysed. Patients referred only for advanced maternal age were analysed in a separate study. Results: the 804 pregnant women were referred for 932 counselling issues. 325 issues (34.9%) were identified during pregnancy and 607 (65.1%) were pre-existing. 81.2% of Italians compared to 41.8% of the non-Italians (P<0.01) had access to counselling before 13 weeks of gestation for risk factors present before pregnancy. An accurate genetic diagnosis was available in 25.0% of cases. In 21.7% of the cases an elevated a priori risk of >10% for the unborn child was established. Conclusions: genetic services provide 37.3% of counselling to pregnant women. Referral for genetic counselling during pregnancy can require considerable resources and pose significant ethical and organizational challenges. New models of pregnancy care in the community need to be developed. General practitioners and gynaecologists have an important role in the referral and in the defence of equity of access and a more structured approach to the participation of medical geneticists to primary practice should be considered

    Building a neurocognitive profile of suicidal risk in severe mental disorders

    Background Research on the influence of neurocognitive factors on suicide risk, regardless of the diagnosis, is inconsistent. Recently, suicide risk studies propose applying a trans-diagnostic framework in line with the launch of the Research Domain Criteria Cognitive Systems model. In the present study, we highlight the extent of cognitive impairment using a standardized battery in a psychiatric sample stratified for different degrees of suicidal risk. We also differentiate in our sample various neurocognitive profiles associated with different levels of risk. Materials and methods We divided a sample of 106 subjects into three groups stratified by suicide risk level: Suicide Attempt (SA), Suicidal Ideation (SI), Patient Controls (PC) and Healthy Controls (HC). We conducted a multivariate Analysis of Variance (MANOVA) for each cognitive domain measured through the standardized battery MATRICS Consensus Cognitive Battery (MCCB). Results We found that the group of patients performed worse than the group of healthy controls on most domains; social cognition was impaired in the suicide risk groups compared both to HC and PC. Patients in the SA group performed worse than those in the SI group. Conclusion Social cognition impairment may play a crucial role in suicidality among individuals diagnosed with serious mental illness as it is involved in both SI and SA; noteworthy, it is more compromised in the SA group fitting as a marker of risk severity

    Lifestyle Interventions and Prevention of Suicide

    Get PDF
    Over the past years, there has been a growing interest in the association between lifestyle psychosocial interventions, severe mental illness, and suicide risk. Patients with severe mental disorders have higher mortality rates, poor health states, and higher suicide risk compared to the general population. Lifestyle behaviors are amenable to change through the adoption of specific psychosocial interventions, and several approaches have been promoted. The current article provides a comprehensive review of the literature on lifestyle interventions, mental health, and suicide risk in the general population and in patients with psychiatric disorders. For this purpose, we investigated lifestyle behaviors and lifestyle interventions in three different age groups: adolescents, young adults, and the elderly. Several lifestyle behaviors including cigarette smoking, alcohol use, and sedentary lifestyle are associated with suicide risk in all age groups. In adolescents, growing attention has emerged on the association between suicide risk and internet addiction, cyberbullying and scholastic and family difficulties. In adults, psychiatric symptoms, substance and alcohol abuse, weight, and occupational difficulties seems to have a significant role in suicide risk. Finally, in the elderly, the presence of an organic disease and poor social support are associated with an increased risk of suicide attempt. Several factors may explain the association between lifestyle behaviors and suicide. First, many studies have reported that some lifestyle behaviors and its consequences (sedentary lifestyle, cigarette smoking underweight, obesity) are associated with cardiometabolic risk factors and with poor mental health. Second, several lifestyle behaviors may encourage social isolation, limiting the development of social networks, and remove individuals from social interactions; increasing their risk of mental health problems and suicide

    Full text link
    [EN] Query-by-example Spoken Term Detection (QbE STD) aims to retrieve data from a speech repository given an acoustic (spoken) query containing the term of interest as the input. This paper presents the systems submitted to the ALBAYZIN QbE STD 2016 Evaluation held as a part of the ALBAYZIN 2016 Evaluation Campaign at the IberSPEECH 2016 conference. Special attention was given to the evaluation design so that a thorough post-analysis of the main results could be carried out. Two different Spanish speech databases, which cover different acoustic and language domains, were used in the evaluation: the MAVIR database, which consists of a set of talks from workshops, and the EPIC database, which consists of a set of European Parliament sessions in Spanish. We present the evaluation design, both databases, the evaluation metric, the systems submitted to the evaluation, the results, and a thorough analysis and discussion. Four different research groups participated in the evaluation, and a total of eight template matching-based systems were submitted. We compare the systems submitted to the evaluation and make an in-depth analysis based on some properties of the spoken queries, such as query length, single-word/multi-word queries, and in-language/out-of-language queries.This work was partially supported by Fundacao para a Ciencia e Tecnologia (FCT) under the projects UID/EEA/50008/2013 (pluriannual funding in the scope of the LETSREAD project) and UID/CEC/50021/2013, and Grant SFRH/BD/97187/2013.

    Lo scopo di tale indagine è stato quello di valutare il livello di contaminazione, l'estensione e l'entità di contaminanti presenti nei suoli superficiali a suo tempo riscontrati mediante il Progetto Pavia. Il monitoraggio ambientale ha interessato un'area di circa 12 ettari che si trova nel comune di Carpiano. Complessivamente sono state identificate 33 aree di campionamento dove sono stati prelevati campioni di suolo sino alla profondità di 30 cm. In ciascun campione di suolo, dopo adeguati trattamenti, è stata valutata la concentrazione di metalli pesanti, metalloidi, macroelementi, sostanza organica, pH, densità apparente, contenuto d'acqua. In alcuni campioni, precisamente 11, si è analizzata la concentrazione di diossine e furani e si è approntato uno studio che ha visto l'utilizzo dei batteri e dei loro prodotti. Lo studio condotto attraverso l'uso dei batteri ha evidenziato anomalie in alcuni punti ad elevata contaminazione. I risultati analitici ottenuti hanno identificato la presenza di una importante contaminazione di metalli pesanti, metalloidi, diossine e furani che interessa un area di alcuni ettari. Tale livello di contaminazione, per la presenza di sostanza organica e per valori ridotti di acidità dei suoli stessi, potrà arrecare danni ingenti all'ambiente.JRC.DDG.H.7-Land management and natural hazard
