    Perinatal Assessment of Paternal Affectivity (PAPA). First validation in Italian samples. Baldoni F.1, Matthey S.2, Agostini F.1, Schimmenti A.3, Caretti V.4 1Department of Psychology, University of Bologna, Italy 2University of Sydney, Australia 3 Kore University of Enna, Italy 4 LUMSA University, Rome, Italy Background: The assessment of affective disorders in fathers during the perinatal period represents a difficult challenge for clinicians. The Perinatal Assessment of Paternal Affectivity (PAPA) (Baldoni et al., 2016) is a new self-report questionnaire for the screening of affective symptoms in fathers during the perinatal period. It has been developed in recent research on perinatal affective disorders and assesses different dimensions of paternal affective problems: anxiety, depression, hostility, relational and couple difficulties, somatic complaints, dangerous behaviors and addictions (smoke, alcohol, drugs, gambling, internet, physical or sexual compulsive and at risk behavior). The PAPA has a simple structure and is very fast and simple to complete. It also considers some ethnic and socio-cultural influences. Aim: This study presents the incoming preliminary data of a multicentric validation study of the PAPA that involved many Italian public services (AUSL Romagna, Cagliari, 15 Alta Padovana, Torino, Foggia, Roma1). Methods: Different samples of fathers and mothers (500 couples, 1000 parents) were involved in the study. All participants, at the VII-VIII months prenatal and at 3 months postnatal, completed the following questionnaires: PAPA (prenatal and postnatal versions), CES-D, SCL-90-R, Analogical Symptom Assessment (ASA), Perceived Stress Scale (PSS), Dyadic Adjustment Scale (DAS), EPDS. Statistical analyses were performed using IBM SPSS Statistics (Version 23). Results: Preliminary findings concerning the prenatal period showed significant association between PAPA total scores (P = .05) and single scale scores with many scores on CES-D, SCL-90-R, ASA, PSS and DAS. Discussion: Preliminary data of this Italian validation study confirm the PAPA as a useful tool for the screening of paternal affective disorders in the perinatal period. However, the PAPA doesn’t permit an accurate diagnosis but provides a simple and practical guide for detecting fathers at high-risk of perinatal affective alteration. In these cases, a more in-depth diagnostic assessment and a possible treatment are required. Reference: Baldoni, F., Matthey, S, Agostini, F., Schimmenti, A., & Caretti, V. (2016).

    Research in the group led by James Wilton‐Ely focuses on catalysis, imaging and sensing. All of this work involves d- and f-elements and is underpinned by the group’s wide-ranging expertise in synthesis. Collaborations with researchers in engineering, medicine and bioimaging allow these discoveries to be used to address major healthcare and sustainability challenges. Professor Wilton-Ely is the author of more than 100 publications and was the recipient of the 2021 Sir Geoffrey Wilkinson Award from the Royal Society of Chemistry for his work on metal-based carbon monoxide sensing. He has a strong interest in sustainability, having directed the MRes Green Chemistry course at Imperial College for over 12 years (2010–2022). He has published on the use of recovered metals in catalysis (1–5), the catalytic transformation of biomass to platform chemicals (6–11) and magnetically-recoverable nanoscale catalysts (12, 13). Elemental sustainability is a pressing concern for all researchers using precious metals and this has led Wilton-Ely to work with colleagues to explore the potential for using gold (3) and palladium (4, 5) complexes recovered from end-of-life products in catalysis

    THE SCREENING OF AFFECTIVE PERINATAL DISORDERS IN FATHERS: PRELIMINARY VALIDATION DATA OF THE PERINATAL ASSESSMENT OF PATERNAL AFFECTIVITY (PAPA) Baldoni Franco (1), Matthey Stephen (2), Agostini Francesca (1), Caretti Vincenzo (3), Minghetti Mattia (1), Giannotti Michele (1), D’Autilia Benedetta (1), Spelzini Federico (4), & the PAPA Team (1) Department of Psychology, University of Bologna, Italy (2) University of Sydney - South West Sydney Local Health District, Sydney, Australia (3) LUMSA University, Roma, Italy (4) Obstetrics and Gynecology Operating Unit, Infermi Hospital Rimini, AUSL Romagna, Italy [email protected] The assessment of perinatal affective disorders in fathers is a still unresolved problem, and currently no screening tool is sufficiently credited. The most common early screening instruments, like the EPDS, even when validated for fathers, do not take into account that men are usually less prone to reveal any psychological difficulty and tend to repress discomfort assuming externalizing strategies like: alcohol abuse, smoking, drug addiction or other maladjusted behaviors. As a consequence of their indefinite clinical features, these problems are often under-assessed or undiagnosed. The Perinatal Assessment of Paternal Affectivity (PAPA) (Baldoni, Matthey, Agostini, Schimmenti, & Caretti, 2016) is a new questionnaire for the screening of high-risk fathers during the perinatal period. It is the first tool for evaluating affective problems in males, considering different dimensions highlighted by recent research. It is fast and easy to administer, ethnic and socio-cultural influences are also considered. The incoming preliminary data from the Italian multicentric validation study of the PAPA, involving many public services (AUSLs Romagna, Cagliari, 15 Alta Padovana, Torino, Foggia and Roma1), will be presented. 600 couples of fathers and mothers (1200 parents) were involved in the study. All participants, at the 7th-8th month prenatal and at 3rd month postnatal, completed the following questionnaires: PAPA, CES-D, SCL-90-R, ASA, PSS, DAS and EPDS. Preliminary findings showed significant association between PAPA total and single scale scores with many scores on CES-D, SCL-90-R, ASA, PSS and DAS (P< .05). These data confirm the PAPA as a useful screening tool for the assessment of perinatal affective disorders in fathers. Despite it doesn’t allow an accurate diagnosis, it provides a simple and practical guide to the detection of high-risk fathers. In these cases, a more thorough diagnostic assessment and a possible treatment are required

    To evaluate future applications of metallic clusters in nanoscience and nanotechnology, the electronic properties of the high-nuclearity carbonyl anionic platinum cluster [Pt19(CO)22]4-were investigated using two different organic cations. In particular, N,N'-diethyl viologen dication (Vio2+) and N,N'-dimethyl-9,9'-bis-Acridinium dication (Acr2+) were employed as counterions, oxidising agents and characterisation probes. The reactions of [Pt19(CO)22]4-tetra-n-butylammonium salt, (TBA+)4([Pt19(CO)22]4-), with both (Vio2+) and (Acr2+), used as tetraphenylborate salts, yielded two new compounds, which were isolated. The stoichiometries and properties of these new compounds were determined and compared on the basis of infrared (IR) solution spectra, electron spin resonance (ESR) analyses, fl uorometric spectra, superconducting quantum interference device (SQUID) magnetometry and resistivity measurements. For Vio2+, a cation-exchange reaction produced the fi nal compound (Vio2+)2([Pt19(CO)22]4-), 'PtVio', which was structurally characterised by single crystal X-ray diffraction (XRD) analysis. However, when using Acr2+, a spontaneous redox reaction occurred and a (Acr+)(TBA+)2([Pt19(CO)22]3-) stoichiometry for the precipitated solid, 'PtAcr', was inferred from the experimental evidence, leading to an interesting 'doubly-radicalic salt'. This new type of salt, consisting of a radical anionic Pt cluster and a radical cation, is characterised by extremely simple synthesis and isolation processes and by the lowest solid-state resistivity found in high-nuclearity cluster salts with redox-Active cations (1)

    We have investigated the transport properties, resistivity and Hall effect, in a series of underdoped GdBa2Cu3Ox thin films grown by off-axis magnetron sputtering. We find a systematic correlation between the critical temperature T-c and the inverse Hall constant R-H(-1), related, in simple models, to the carrier concentration n. Our experimental thin film T-c(n) data are in good agreement with the temperature-doping phase diagram obtained for YBa2Cu3Ox, single crystals. By measuring the activation energies in the liquid vortex phase, and by using a 2-dimensional model for vortex dynamics, we have extracted the penetration depth of these samples, and studied the relation between the carrier concentration and the superfluid density to probe the role of phase fluctuations on superconductivity
