Extraction and Classification of Acoustic Features from Italian Speaking Children with Autism Spectrum Disorders

Autism Spectrum Disorders (ASD) are a group of complex developmental conditions whose effects and severity show high intraindividual variability. However, one of the main symptoms shared along the spectrum is social interaction impairments that can be explored through acoustic analysis of speech production. In this paper, we compare 14 Italian-speaking children with ASD and 14 typically developing peers. Accordingly, we extracted and selected the acoustic features related to prosody, quality of voice, loudness, and spectral distribution using the parameter set eGeMAPS provided by the openSMILE feature extraction toolkit. We implemented four supervised machine learning methods to evaluate the extraction performances. Our findings show that Decision Trees (DTs) and Support Vector Machines (SVMs) are the best-performing methods. The overall DT models reach a 100% recall on all the trials, meaning they correctly recognise autistic features. However, half of its models overfit, while SVMs are more consistent. One of the results of the work is the creation of a speech pipeline to extract Italian speech biomarkers typical of ASD by comparing our results with studies based on other languages. A better understanding of this topic can support clinicians in diagnosing the disorder

Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition)

The third edition of Flow Cytometry Guidelines provides the key aspects to consider when performing flow cytometry experiments and includes comprehensive sections describing phenotypes and functional assays of all major human and murine immune cell subsets. Notably, the Guidelines contain helpful tables highlighting phenotypes and key differences between human and murine cells. Another useful feature of this edition is the flow cytometry analysis of clinical samples with examples of flow cytometry applications in the context of autoimmune diseases, cancers as well as acute and chronic infectious diseases. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid. All sections are written and peer‐reviewed by leading flow cytometry experts and immunologists, making this edition an essential and state‐of‐the‐art handbook for basic and clinical researchers.DFG, 389687267, Kompartimentalisierung, Aufrechterhaltung und Reaktivierung humaner Gedächtnis-T-Lymphozyten aus Knochenmark und peripherem BlutDFG, 80750187, SFB 841: Leberentzündungen: Infektion, Immunregulation und KonsequenzenEC/H2020/800924/EU/International Cancer Research Fellowships - 2/iCARE-2DFG, 252623821, Die Rolle von follikulären T-Helferzellen in T-Helferzell-Differenzierung, Funktion und PlastizitätDFG, 390873048, EXC 2151: ImmunoSensation2 - the immune sensory syste

Gender differences in heroin addiction and treatment: results from the VEdeTTE cohort

Background: Gender differences strongly affect heroin addiction, from risk factors to patterns of consumption, access to treatments, and outcomes. Objectives: To investigate gender differences in the VEdeTTE cohort of heroin addicts. Methods: VEdeTTE is a cohort of 10,454 heroin users enrolled between 1998 and 2001 in 115 public drug treatment centres in Italy. Clinical and personal information were collected at intake through a structured interview. Treatments were recorded using a standardized form. Gender differences were explored with regard to characteristics at intake, treatments, and retention in methadone maintenance and therapeutic community. Cox Proportional models were carried out to identify risk factors for treatment abandon. Results: Compared with men, at their first access to treatment women with drug addiction were younger, more frequently married, legally separated, divorced or widow, unemployed though better educated, HIV+; more frequently they lived with their partner and sons. They reported a higher use of sedatives, but a lower use of alcohol; more frequently they had psychiatric comorbidity, including depression, self-injuries, and suicide attempts. Psychotherapy was more frequently prescribed to women, pharmacological treatments to men. Methadone maintenance was less frequently abandoned by women. Drug abuse severity factors predicted abandon of methadone among women. High methadone doses and the combination with psychotherapy improved treatment retention in both genders. Low education level and severity factors among women and young age among men predicted abandon of therapeutic community. Conclusions: Gender differences in the VEdeTTE cohort suggest the need of a gender sensitive approach to improve treatment outcomes among heroin addicts

Paediatric anti-N-methyl-D-aspartate receptor encephalitis: The first Italian multicenter case series

Given the rarity of this condition, especially in children, there is a paucity of large reported paediatric case series of anti-N-methyl-d-aspartate receptor encephalitis.METHODS:To contribute to define the features of this condition, we describe retrospectively a new nationwide case series of 20 children (50% females), referred by 13 Italian centres.RESULTS:Mean age at onset was 8 years (range 3-17). Prodromal symptoms were reported in 31.6%; onset was with neurological symptoms in 70%, and with behavioural/psychiatric disturbances in 30%. Most patients developed a severe clinical picture (90%), and 41% experienced medical complications; children 12-18 years old seemed to be more severe and symptomatic than younger patients. All children received first-line immune therapy; second-line treatment was administered to 45%. Relapses occurred in 15%. At last follow-up (mean 23.9 months, range 5-82), 85% patients had mRS 0-1; this rate was higher among older patients, and in those receiving first immune therapy within 1 month.CONCLUSIONS:Our case series confirms a symptomatologic core of paediatric anti-N-methyl-d-aspartate receptor encephalitis, even though displaying some distinctive features that may be explained by a specific genetic background or by the limited number of patients. The growing incidence of this condition, the relative age-dependent variability of its manifestations, the availability of immunotherapy and the possible better outcome with early treatment impose a high index of clinical suspicion be maintained. In the absence of data suggesting other specific etiologies, paediatricians should consider this diagnosis for children presenting with neurological and/or behavioural or psychiatric disturbances, regardless of age and gender
