Background
Globally, stigma associated with mental, neurological and substance use (MNS) disorders is rampant and a barrier to good health and overall well-being of people with these conditions. Person-centred digital approaches such as participatory video may reduce stigma, but evidence on their effectiveness in Africa is absent.
AimsTo evaluate the effectiveness of participatory video in reducing mental health-related stigma in a resource-limited setting.
MethodWe evaluated the effectiveness of using participatory video and face-to-face interaction between people with MNS disorders and a target audience in lowering stigma among 420 people living in Kilifi, Kenya. Changes in knowledge, attitudes and behaviour (KAB) were measured by comparing baseline scores with scores immediately after watching the participatory videos and 4 months after the intervention. Sociodemographic correlates of stigma scores were examined using multivariable linear regression models.
ResultsCompared with baseline, KAB scores significantly improved at both time points, suggesting reduced stigma levels. At 4 months, the changes in scores were: knowledge (β = 0.20, 95% CI 0.16–0.25; P < 0.01), liberal attitude (β = 1.08, 95% CI 0.98–1.17; P < 0.01), sympathetic attitude (β = 0.52, 95% CI 0.42–0.62; P < 0.01), tolerant attitude (β = 0.72, 95% CI 0.61–0.83; P < 0.01) and behaviour (β = 0.37, 95% CI 0.31–0.43; P < 0.01). Sociodemographic variables were significantly correlated with KAB scores; the correlations were not consistent across the domains.
ConclusionsParticipatory video is a feasible and effective strategy in improving knowledge, attitudes and intended behaviour in a resource-limited setting. Further studies are required to understand the mechanisms through which it lowers stigma and to examine long-term sustainability and the effectiveness of multicomponent interventions.

Irritability is a transdiagnostic symptom dimension in developmental psychopathology, closely related to the Research Domain Criteria (RDoC) construct of frustrative nonreward. Consistent with the RDoC framework and calls for transdiagnostic, developmentally-sensitive assessment methods, we report data from a smartphone-based, naturalistic ecological momentary assessment (EMA) study of irritability. We assessed 109 children and adolescents (Mage = 12.55 years; 75.20% male) encompassing several diagnostic groups – disruptive mood dysregulation disorder (DMDD), attention-deficit/hyperactivity disorder (ADHD), anxiety disorders (ANX), healthy volunteers (HV). The participants rated symptoms three times per day for 1 week. Compliance with the EMA protocol was high. As tested using multilevel modeling, EMA ratings of irritability were strongly and consistently associated with in-clinic, gold-standard measures of irritability. Further, EMA ratings of irritability were significantly related to subjective frustration during a laboratory task eliciting frustrative nonreward. Irritability levels exhibited an expected graduated pattern across diagnostic groups, and the different EMA items measuring irritability were significantly associated with one another within all groups, supporting the transdiagnostic phenomenology of irritability. Additional analyses utilized EMA ratings of anxiety as a comparison with respect to convergent validity and transdiagnostic phenomenology. The results support new measurement tools that can be used in future studies of irritability and frustrative nonreward.

Introduction
A connection between balance system dysfunction and Agoraphobia (AG) in Panic Disorder (PD) has been found. Balance control of many patients with PD and AG rely mainly on visual cues (visual dependence) and moving visual stimuli in their peripheral visual field induce postural instability and anxiety. These features may maintain agoraphobic symptoms after standard treatments.
ObjectivesTo study whether balance rehabilitation with moving peripheral visual stimuli would benefit patients with PD and AG not fully responders to standard treatments.
MethodsSix patients with PD and AG were included. Inclusion criteria: 1) panic-phobic symptoms despite adequate treatments (SSRIs for at least 3 months; cognitive behavioral therapy) and 2) balance dysfunction with instability during peripheral visual stimuli (posturography with and without peripheral visual stimulation).
The patients went through 10 sessions (3 sessions/week) of balance rehabilitation: static and dynamic exercises, with movements of eyes and head, during projection of peripheral visual stimuli (video-films, 32 times-accelerated, on large lateral screens). Descriptive and non-parametric analyses were applied.
ResultsAfter rehabilitation, the patients showed significant improvement both in panic-phobic symptoms (specific psychometric scale scores) (p < 0.05) and in balance performance (post-rehabilitation posturography with and without peripheral visual stimulation) (p < 0.05).
ConclusionsBalance rehabilitation with peripheral visual stimuli may increase the efficacy of standard treatments in patients with PD and AG and visual-balance dysfunction. Mechanisms of physical and emotional habituation to environmental destabilizing stimuli may be involved. Further larger and controlled studies are warranted.

Introduction
The screen for cognitive impairment in psychiatry (SCIP) is a brief, accessible scale designed for detecting cognitive deficits in psychiatric disorders.
ObjectivesThe objective of this study is to test the SCIP's validity as a cognitive test by comparison with standard neuropsychological scale using the Pearson's correlation.
Aims Test the convergent and discriminant validity of the SCIP within the Italian SCIP validation project.
MethodsPatients between 18 and 65 years who are in a stable phase of the disease, diagnosed with schizophrenia, schizoaffective disorder or bipolar I disorder were enrolled in this study, from the community mental health department of Ferrara.
ResultsThe tests were administered to 110 patients (mean age: 45 ± 11,4) and to 86 controls (mean age: 35 ± 12,6) of both sex. SCIP presents high correlation with the R-BANS total score (P < 0.01) and the subscales (verbal learning test-immediate, working memory, verbal fluency test, verbal learning test-delayed, processing speed test, P < 0.01). There are significant differences (P < 0.01) in all SCIP dimensions between patient and control group (Table 1).
ConclusionsOur analysis confirm the results of the English, French and Spanish version of the SCIP regarding convergent and discriminant validity. The SCIP represents a valid, simple and brief screening tool for the cognitive evaluation of patients with schizophrenia-spectrum disorders.

Objective
Mental disorders can have a major impact on brain development. Peripheral blood concentrations of brain-derived neurotrophic factor (BDNF) are lower in adult psychiatric disorders. Serum BDNF concentrations and BDNF genotype have been associated with cortical maturation in children and adolescents. In 2 large independent samples, this study tests associations between serum BDNF concentrations, brain structure, and psychopathology, and the effects of BDNF genotype on BDNF serum concentrations in late childhood and early adolescence.
MethodsChildren and adolescents (7-14 years old) from 2 cities (n = 267 in Porto Alegre; n = 273 in São Paulo) were evaluated as part of the Brazilian high-risk cohort (HRC) study. Serum BDNF concentrations were quantified by sandwich ELISA. Genotyping was conducted from blood or saliva samples using the SNParray Infinium HumanCore Array BeadChip. Subcortical volumes and cortical thickness were quantified using FreeSurfer. The Development and Well-Being Behavior Assessment was used to identify the presence of a psychiatric disorder.
ResultsSerum BDNF concentrations were not associated with subcortical volumes or with cortical thickness. Serum BDNF concentration did not differ between participants with and without mental disorders, or between Val homozygotes and Met carriers.
ConclusionsNo evidence was found to support serum BDNF concentrations as a useful marker of developmental differences in brain and behavior in early life. Negative findings were replicated in 2 of the largest independent samples investigated to date.

Background
The classification of psychological distress and illness behavior in the setting of medical disease is still controversial. Current psychiatric nosology does not seem to cover the spectrum of disturbances. The aim of this investigation was to assess whether the joint use of DSM-IV categories and the Diagnostic Criteria for Psychosomatic Research (DCPR), that provide identification of syndromes related to somatization, abnormal illness behavior, irritable mood, type A behavior, demoralization and alexithymia, could yield subtyping of psychosocial variables in the medically ill.
MethodA cross-sectional assessment using both DSM-IV and the DCPR was conducted in eight medical centers in the Italian Health System. Data were submitted to cluster analysis. Participants were consecutive medical out-patients and in-patients for whom a psychiatric consultation was requested. A total of 1700 subjects met eligibility criteria and 1560 agreed to participate.
ResultsThree clusters were identified: non-specific psychological distress, irritability and affective disturbances with somatization.
ConclusionsTwo-step cluster analysis revealed clusters that were found to occur across clinical settings. The findings indicate the need of expanding clinical assessment in the medically ill to include the various manifestations of somatization, illness behavior and subclinical distress encompassed by the DCPR.

The science of extra-solar planets is one of the most rapidly changing areas of astrophysics and since 1995 the number of planets known has increased by almost two orders of magnitude. A combination of ground-based surveys and dedicated space missions has resulted in 560-plus planets being detected, and over 1200 that await confirmation. NASA's Kepler mission has opened up the possibility of discovering Earth-like planets in the habitable zone around some of the 100,000 stars it is surveying during its 3 to 4-year lifetime. The new ESA's Gaia mission is expected to discover thousands of new planets around stars within 200 parsecs of the Sun. The key challenge now is moving on from discovery, important though that remains, to characterisation: what are these planets actually like, and why are they as they are?
In the past ten years, we have learned how to obtain the first spectra of exoplanets using transit transmission and emission spectroscopy. With the high stability of Spitzer, Hubble, and large ground-based telescopes the spectra of bright close-in massive planets can be obtained and species like water vapour, methane, carbon monoxide and dioxide have been detected. With transit science came the first tangible remote sensing of these planetary bodies and so one can start to extrapolate from what has been learnt from Solar System probes to what one might plan to learn about their faraway siblings. As we learn more about the atmospheres, surfaces and near-surfaces of these remote bodies, we will begin to build up a clearer picture of their construction, history and suitability for life.
The Exoplanet Characterisation Observatory, EChO, will be the first dedicated mission to investigate the physics and chemistry of Exoplanetary Atmospheres. By characterising spectroscopically more bodies in different environments we will take detailed planetology out of the Solar System and into the Galaxy as a whole.
EChO has now been selected by the European Space Agency to be assessed as one of four M3 mission candidates.

Artificial opal films have been prepared by sedimentation of monodisperse silica spheres in water suspension. Atomic force microscope images show a triangular packing of the spheres at the surface of the films. The presence and the energy position of an optical pseudo gap in incidence-angle-dependent transmittance and reflectance spectra is observed and accounted for by theoretical calculations of the photonic band structure. These calculations indicate that the pseudo gap is due to the splitting of the photonic bands in the L point of the Brillouin zone. The spectroscopic data show additional loss structures due to both other features of the Brillouin zone and the diffraction of the light from the regular surface of the sample. The effect of the infiltration of opals with polydiacetylene solutions is also reported.

Background. Recent literature has demonstrated that psychiatric patients, particularly those with a diagnosis of schizophrenia, may be at high risk for HIV infection. In fact, HIV-risk behaviour, such as intravenous drug with sharing needles, promiscuity associated with unprotected sex and high-risk sexual activity after using drugs has been reported by a substantial proportion of mentally ill patients.
Methods. In order to examine this problem in Italy, HIV-risk taking behaviour and knowledge about HIV/AIDS was investigated among 91 schizophrenic patients by using two self-report questionnaires (HIV-Risk Behaviour Questionnaire; AIDS-Risk Behaviour Knowledge Test).
Results. One-third of the patients reported having been tested for HIV infection and one tested seropositive (prevalence 3·4%). A high proportion of patients reported HIV-risk behaviour, such as injected drugs use (22·4%) and engaging in high risk sexual activity (e.g. multiple partners, 58%; prostitutes, 45%; occasional partners, 37%). Condoms were ‘never used’ by 41% of the patients and ‘almost never used’ by another 25%. In spite of these behaviours, 65% reported no concern of HIV infection. Knowledge about AIDS was lower among psychiatric patients than a healthy control group. Patients with long-lasting illness and numerous psychiatric admissions were less acknowledgeable about HIV infection. Certain misconceptions on HIV transmission were related to HIV risk behaviour.
Conclusions. These results indicate the urgent need for HIV educational programmes within mental health community-care settings.
