We present the Pilot Survey Phase 2 data release for the Wide-field ASKAP L-band Legacy All-sky Blind surveY (WALLABY), carried-out using the Australian SKA Pathfinder (ASKAP). We present 1760 H i detections (with a default spatial resolution of 30′′) from three pilot fields including the NGC 5044 and NGC 4808 groups as well as the Vela field, covering a total of $\sim 180$ deg$^2$ of the sky and spanning a redshift up to $z \simeq 0.09$. This release also includes kinematic models for over 126 spatially resolved galaxies. The observed median rms noise in the image cubes is 1.7 mJy per 30′′ beam and 18.5 kHz channel. This corresponds to a 5$\sigma$ H i column density sensitivity of $\sim 9.1\times10^{19}(1 + z)^4$ cm$^{-2}$ per 30′′ beam and $\sim 20$ km s$^{-1}$ channel and a 5$\sigma$ H i mass sensitivity of $\sim 5.5\times10^8 (D/100$ Mpc)$^{2}$ M$_{\odot}$ for point sources. Furthermore, we also present for the first time 12′′ high-resolution images (“cut-outs”) and catalogues for a sub-sample of 80 sources from the Pilot Survey Phase 2 fields. While we are able to recover sources with lower signal-to-noise ratio compared to sources in the Public Data Release 1, we do note that some data quality issues still persist, notably, flux discrepancies that are linked to the impact of side lobes associated with the dirty beams due to inadequate deconvolution. However, in spite of these limitations, the WALLABY Pilot Survey Phase 2 has already produced roughly a third of the number of HIPASS sources, making this the largest spatially resolved H i sample from a single survey to date.
We present the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) Pilot Phase I Hi kinematic models. This first data release consists of Hi observations of three fields in the direction of the Hydra and Norma clusters, and the NGC 4636 galaxy group. In this paper, we describe how we generate and publicly release flat-disk tilted-ring kinematic models for 109/592 unique Hi detections in these fields. The modelling method adopted here—which we call the WALLABY Kinematic Analysis Proto-Pipeline (WKAPP) and for which the corresponding scripts are also publicly available—consists of combining results from the homogeneous application of the FAT and 3DBarolo algorithms to the subset of 209 detections with sufficient resolution and $S/N$ in order to generate optimised model parameters and uncertainties. The 109 models presented here tend to be gas rich detections resolved by at least 3–4 synthesised beams across their major axes, but there is no obvious environmental bias in the modelling. The data release described here is the first step towards the derivation of similar products for thousands of spatially resolved WALLABY detections via a dedicated kinematic pipeline. Such a large publicly available and homogeneously analysed dataset will be a powerful legacy product that that will enable a wide range of scientific studies.
Long-acting injectable (LAI) antipsychotics have been used as an alternative to oral antipsychotic formulations.
Aims:
to evaluate the impact of switching to a LAI second-generation antipsychotic (SGA) in terms of changes in patient's psychopathology, subjective experience of drug and quality of life.
Methods:
18 adult outpatients diagnosed with Schizoaffective disorder (by means of the SCID-I/P) and attending the Psychiatric Unit of the University of Florence were recruited. All patients were under a stabilized therapy with a single oral SGA (either olanzapine or paliperidone) and were switched to its corresponding LAI formulation (olanzapine pamoate or paliperidone palmitate). Patients were assessed by means of the following questionnaires: MADRS, YMRS, PANSS, DAI-10, SWN and SF-36 at enrolment (T0) and after 6 months (T1).
Results:
A significant reduction was found between T0 and T1 (p<.05) in PANSS total, negative and general psychopathology mean scores, as well as in mean MADRS and YMRS total scores. No difference was found for positive PANSS mean scores. We observed a significant increase of mean DAI-10 and SWN total scores between T0 and T1 (p<.05). A reduction of side effects like sedation and blunted affect between T0 and T1 (p<.05) was confirmed by significant increases in mean SF-36 subscales scores, such as: general health (p<.01) change in health (p<.01) and social integration (p<.05).
Conclusions:
Treatment with LAI SGAs seems to be a valid alternative in patients with Schizoaffective disorder. Our preliminary data suggest an improvement in patient's subjective experience of pharmacological therapy and health-related quality of life, together with a similar efficacy on psychopathology.
Aberrant salience consists of the unusual or incorrect assignment of salience, significance or value to different innocuous stimuli. It has been hypothesized that subjects with an aberrant salience could be proneness to develop psychosis. Despite the importance of this concept in psychosis, only few instruments assess aberrant salience.
Objectives and aims
To evaluate aberrant salience processing in a clinical trans-diagnostic sample and its relationship with psychotic symptoms.
Methods
Thirty-six outpatient subjects attending the Psychiatric Unit of the University of Florence were recruited: 9 with Major Depression Disease (MDD), 8 with Schizophrenia (SC), 19 with Bipolar Disorder (BD). Patients were assessed by means of a clinical interview (SCID-I/P) and several questionnaires, including the Aberrant Salience Inventory (ASI).
Results
The three groups showed significant differences in the lifetime presence of psychotic symptoms, with higher frequency in BD and SC patients (p< 0.01). Significant differences in ASI scores were found between MDD and BD (p< 0.01), and SC and BD (p< 0.01), while any difference between BD and SC was observed. Subjects with positive ASI (cut-off>14) reported more frequently past and lifetime psychotic symptoms (p< 0.01) and constituted a distinct cluster from patients with ASI score < 14.
Conclusion
Aberrant salience is significantly associated to lifetime psychotic symptoms. Thus it represents a relevant psychopathologic dimension that requires a careful investigation in patients with an history of psychotic events. The ASI could represent an useful instrument to evaluate the proneness of clinical and pre-clinical samples to develop psychotic symptoms.
Aberrant salience is the incorrect assignment of salience, significance or value to different innocuous stimuli. It seems closely related with dysregulation of the dopamine system that in turn relates with proneness to develop psychosis.
Objectives
To evaluate aberrant salience processing in a clinical trans-diagnostic sample, its relationship with anamnestic psychotic symptoms and current psychopathology, and possible variations of aberrant salience after three months of clinical-based treatment.
Methods
Twenty inpatient subjects attending the Psychiatric Unit (Florence University) were recruited: 3 with Major Depression Disease, 6 with Schizophrenia, 3 with Bipolar Disorder, 4 with Obsessive-Compulsive Disorder, 4 with Eating Disorders. Patients were assessed by means of a clinical interview (SCID-I/P) and several questionnaires (AMDP, MADRS, HAM-A, MRS, PANSS and Aberrant Salience Inventory-ASI) at enrolment (T0) and after an individual and clinical-based treatment lasting 3 months (T1).
Results
At T0 subjects with positive ASI (cut-off>14) reported more frequently past and lifetime psychotic symptoms (p<0.05) and constituted a distinct cluster from patients with ASI score < 14. A positive anamnesis of psychotic symptoms was significantly correlated with AMDP susbscales (delusions and perception disturbances), PANSS pos, PANSS neg, PANSS tot scores (p<0.05). A significant reduction of mean MADRS, PANSS tot and HAM scores between T0 and T1 was found (p<0.05). No differencesin ASI scores between T0 and T1 were observed.
Conclusion
Aberrant salience is significatively associated to lifetime psychotic symptoms. It represents a relevant psychopathologic dimension that, unlike other symptoms, seems not to significatively modify after pharmacological treatment and could represent a stable lifetime.
The relationships between Eating Disorders (EDs) and sexuality are complex, and of interest for researchers and clinicians.
Objective
To identify psychopathological and clinical factors associated with restoration of regular menses and sexual function in EDs patients.
Aims
To evaluate the role of sexuality as a moderator of the recovery process after an individual Cognitive Behavioural Therapy (CBT).
Methods
39 Anorexia Nervosa (AN) and 40 Bulimia Nervosa (BN) female patients were evaluated by means of a face-to-face interview, self-reported questionnaires, including Eating Disorder Examination Questionnaire and Female Sexual Function Index, and blood sample for hormonal levels and biomarkers. The assessments were repeated at baseline, at one year follow up, and at three years follow up.
Results
After CBT, both AN and BN patients showed a significant improvement of sexual functioning, which was associated with a reduction of core psychopathology. AN patients who recovered regular menses demonstrated a better improvement across time of psychopathological and clinical features, and were more likely to maintain these improvements at follow up. Recovery of regular menses and improvement of sexuality at the end of CBT were associated with a higher probability to have a full recovery at three years follow up.
Conclusions
These results challenge a concept of recovery in EDs exclusively based on weight restoration or behavioral changes. An assessment including sexual functioning and core psychopathology might identify the residual pathological conditions, and it is able to provide information regarding the long term recovery process.

The process whereby objects and representations come to be attention grabbing and capture thought and behaviour is called salience, and it is defined as aberrant when a significance is allocated to neutral stimuli. The Aberrant Salience Inventory (ASI) is a scale to measure aberrant salience, characterized by 29 dichotomic items. By now, a correlation between aberrant salience and eating disorders is unknown. Aim of this study is to evaluate an alteration of salience in patients with anorexia nervosa, to estimate the existance of a correlation between aberrant salience and the experience of body shape.
Methods
Twenty-six female patients with AN (diagnosed using DSM-5) were enrolled at the Psychiatry Department of Florence. Psychopathological features were assessed at the time of enrollment using the following scales: SCL-90-R, BUT, EDE-Q. Salience alteration was assessed by the means of the ASI. Statistical analysis were realized using SPSS 20.0 with Spearman bivariate correlation.
Results
Mean age was (mean ± SD) 26.2 ± 8.72 and mean Body Mass Index (BMI) 16.1 ± 2.46. Global Severity Index (GSI), Positive Symptom Total (PST) and Positive Symptom Distress Symptom Index (PSDI) were estimated for BUT and SCL-90-R and compared to total value of ASI. Thus, we found a statistical significant (P < 0.05) direct correlation between ASI and BUTpsdi and ASI and SCL-90-Rgsi (correlation coefficient of 0.446 and 0.398, respectively).
Conclusion
In this study, we found a significant direct correlation between Aberrant Salience Inventory (ASI) values and one dimension of body uneasiness in anorexic patients. These preliminary data need further studies with a wider sample to confirm the above-mentioned data.

Background:ATP8A2 mutations have only recently been associated with human disease. We present the clinical features from the largest cohort of patients with this disorder reported to date. Methods: An observational study of 9 unreported and 2 previously reported patients with biallelic ATP8A2 mutations was carried out at multiple centres. Results: The mean age of the cohort was 9.4 years old (range: 2.5-28 yrs). All patients demonstrated developmental delay, severe hypotonia and movement disorders: chorea/choreoathetosis (100%), dystonia (27%) or facial dyskinesia (18%). Hypotonia was apparent at birth (70%) or before 6 months old (100%). Optic atrophy was observed in 75% of patients who had a funduscopic examination. MRI of the brain was normal for most patients with a small proportion showing mild cortical atrophy (30%), delayed myelination (20%) and/or hypoplastic optic nerves (20%). Epilepsy was seen in two older patients. Conclusions:ATP8A2 gene mutations have emerged as a cause of a novel phenotype characterized by developmental delay, severe hypotonia and hyperkinetic movement disorders. Optic atrophy is common and may only become apparent in the first few years of life, necessitating repeat ophthalmologic evaluation. Early recognition of the cardinal features of this condition will facilitate diagnosis of this disorder.
