Neuropsychological (NP) tests are increasingly computerized, which automates testing, scoring, and administration. These innovations are well-suited for use in resource-limited settings, such as low- to middle- income countries (LMICs), which often lack specialized testing resources (e.g., trained staff, forms, norms, equipment). Despite this, there is a dearth of research on their acceptability and usability which could affect performance, particularly in LMICs with varying levels of access to computer technology. NeuroScreen is a tablet-based battery of tests assessing learning, memory, working memory, processing speed, executive functions, and motor speed. This study evaluated the acceptability and usability of NeuroScreen among two groups of LMIC adolescents with and without HIV from Cape Town, South Africa and Kampala, Uganda.

Adolescents in Cape Town (n=131) and Kampala (n=80) completed NeuroScreen and questions about their use and ownership of, as well as comfort with computer technology and their experiences completing NeuroScreen. Participants rated their technology use -comfort with and ease-of-use of computers, tablets, smartphones, and NeuroScreen on a Likert-type scale: (1) Very Easy/Very Comfortable to (6) Very Difficult/Very Uncomfortable. For analyses, responses of Somewhat Easy/Comfortable to Very Easy/Comfortable were collapsed to codify comfort and ease. Descriptive statistics assessed technology use and experiences of using the NeuroScreen tool. A qualitative question asked how participants would feel receiving NeuroScreen routinely in the future; responses were coded as positive, negative, or neutral (e.g., “I would enjoy it”). Chi-squares assessed for group differences.

South African adolescents were 15.42 years on average, 50.3% male, and 49% were HIV-positive. Ugandan adolescents were 15.64 years on average, 50.6% male, and 54% HIVpositive. South African participants were more likely than Ugandan participants to have ever used a computer (71% vs. 49%; p<.005), or tablet (58% vs. 40%; p<.05), whereas smartphone use was similar (94% vs 87%). South African participants reported higher rates of comfort using a computer (86% vs. 46%; p<.001) and smartphone (96% vs. 88%; p<.05) compared to Ugandan participants. Ugandan adolescents rated using NeuroScreen as easier than South African adolescents (96% vs. 87%; p<.05).). Regarding within-sample differences by HIV status, Ugandan participants with HIV were less likely to have used a computer than participants without HIV (70% vs. 57%; p<.05, respectively).The Finger Tapping test was rated as the easiest by both South African (73%) and Ugandan (64%) participants. Trail Making was rated as the most difficult test among Ugandan participants (37%); 75% of South African participants reported no tasks as difficult followed by Finger Tapping as most difficult (8%). When asked about completing NeuroScreen at routine doctor’s visits, most South Africans (85%) and Ugandans (72%) responded positively.

This study found that even with low prior tablet use and varying levels of comfort in using technology, South African and Ugandan adolescents rated NeuroScreen with high acceptability and usability. These data suggest that scaling up NeuroScreen in LMICs, where technology use might be limited, may be appropriate for adolescent populations. Further research should examine prior experience and comfort with tablets as predictors NeuroScreen test performance.

Cardiometabolic diseases are responsible for the majority of premature deaths in people with schizophrenia. This study aimed to quantify the fatal burden of ischaemic heart disease (IHD), stroke and diabetes attributable to schizophrenia.

Comparative Risk Assessment methodology from the Global Burden of Disease (GBD) study was used to calculate attributable burden; pooled relative risks (RRs) for IHD, stroke and diabetes were estimated via meta-regression, which were combined with GBD schizophrenia prevalence estimates to calculate the deaths and years of life lost (YLLs) caused by these health outcomes that were attributable to schizophrenia. The proportion of explained all-cause fatal burden and corresponding unexplained burden was also calculated.

The pooled RRs for IHD, stroke and diabetes mortality were 2.36 [95% uncertainty interval (UI) 1.77 to 3.14], 1.86 (95% UI 1.36 to 2.54) and 4.08 (95% UI 3.80 to 4.38) respectively. Schizophrenia was responsible for around 50 000 deaths and almost 1.5 million YLLs globally in 2019 from these health outcomes combined. IHD, stroke and diabetes together explained around 13% of all deaths and almost 11% of all YLLs attributable to schizophrenia, resulting in 320 660 (95% UI 288 299 to 356 517) unexplained deaths and 12 258 690 (95% UI 10 925 426 to 13 713 646) unexplained YLLs.

Quantifying the physical disease burden attributable to schizophrenia provides a means of capturing the substantial excess mortality associated with this disorder within the GBD framework, contributing to an important evidence base for healthcare planning and practice.

Bipolar disorder (BD) is a psychiatric disorder characterized by alternating episodes of high mood and low mood similar to depression. To differentiate BD patients from unipolar (UN) depressed patients remains a challenge and the clinical scales available failed to distinguish these 2 populations. ALCEDIAG developed EDIT-B, the first blood test able to make a differential diagnosis of BD. Based on RNA editing modifications measurement and AI, the test requires a simple blood draw and equipment available in most central laboratories. A first study on 160 UN and 95 BD patients allowed a differential diagnosis with an AUC of 0.935 and high specificity (Sp=84.6%) and sensitivity (Se=90.9%). A multicentric clinical study has been set up to validate these performances.

The objective of this project is to run a multicentric clinical study in Europe and assess the performances of the test.

The EDIT-B project, led by Alcediag, is supported by EIT-Health grant (European institute of Innovation and Technology) and gathers 4 clinical centers in 3 countries (France, Spain, Danemark), a CRO for the clinical study management (Aixial), a CRO for the development of a diagnostic kit (Veracyte), a diagnostic lab for molecular biology analyses (Synlab), and a regulatory company (PLG).

At the end of the study, the EDIT-B performance will be confirmed and the test will be CE-marked.

This test will address the needs of millions of patients suffering from misdiagnosis and therefore allow them to receive the correct treatment.

There is currently little nationally representative diagnostic data available to quantify how many Aboriginal and Torres Strait Islander people may need a mental health service in any given year. Without such information, health service planners must rely on less direct indicators of need such as service utilisation. The aim of this paper is to provide a starting point by estimating the prevalence ratio of 12-month common mental disorders (i.e. mood and anxiety disorders) for Indigenous peoples compared to the general Australian population.

Analysis of the four most recent Australian Indigenous and corresponding general population surveys was undertaken. Kessler-5 summary scores by 10-year age group were computed as weighted percentages with corresponding 95% confidence intervals. A series of meta-analyses were conducted to pool prevalence ratios of Indigenous to general population significant psychological distress by 10-year age groups. The proportion of respondents with self-reported clinician diagnoses of mental disorders was also extracted from the most recent survey iterations.

Indigenous Australians are estimated to have between 1.6 and 3.3 times the national prevalence of anxiety and mood disorders. Sensitivity analyses found that the prevalence ratios did not vary across age group or survey wave.

To combat the current landscape of inequitable mental health in Australia, priority should be given to populations in need, such as Indigenous Australians. Having a clear idea of the current level of need for mental health services will allow planners to make informed decisions to ensure adequate services are available.

There is little or no information comparing working experience, including burnout, amongst psychiatry residents internationally. We present preliminary findings from six of the first countries to complete data collection.

To obtain data from psychiatric residents in over twenty countries regarding rates of burnout, depression and suicidality and their associations with working conditions and personality traits.

An online survey incorporating the Maslach Burnout Inventory General Survey (MBI-GS), Areas of Work Life Survey (AWLS), Patient Health Questionnaire-9 (PHQ-9), Suicide Ideation and Behaviour Questionnaire (SIBQ), Big Five Inventory - 10 (BFI-10) and questions on demographics and working circumstances was designed, and checked by national co-ordinators for suitability in each participating country, prior to agreeing the final version. This was then translated and back-translated before being sent to participants. A stratified hierarchy sample methodology was developed and used to obtain the best possible study population in each country. This allowed us to maximise participation despite major differences in ease of access to residents across the study countries. The aim of studying the whole resident population was achieved in a large number of countries. Data was then analysed by the study statistician using SPSS. No funding was received for the study.

Data from Croatia (n=106), France (n=374), Hungary (n=81), Italy (n=180), Romania (n=52) and United Kingdom (n>2000) revealed marked differences between countries in the factors studied including in working circumstances, rates of burnout and suicidality. The associations discovered may help further improve psychiatric training experience internationally.

The diagnostic boundaries of social anxiety disorder (SAD) are still controversial and recent evidence suggests that the condition could be better understood as a continuum of severity, rather than a strictly circumscribed entity. Current neuroanatomical theories on SAD support the involvement of limbic structures in its pathophysiology, with an emphasis on the amygdala. Thus, the objective of this study was to investigate the hypothesis of volumetric alterations in the amygdala of subjects in different points of the social anxiety spectrum.

The sample consisted of patients with generalized SAD (n=17), subthreshold SAD (increased social anxiety without avoidance; n=13), and healthy controls (n=15). Participants underwent structural magnetic resonance scans and the volume of the bilateral amygdala was manually determined.

Significantly greater volumes of bilateral amygdala were found in socially anxious individuals. Amygdala volumes of subthreshold SAD participants fell between the values found for generalized SAD and healthy controls.

Individuals suffering from SAD have greater amygdala volumes compared to controls and this difference seems to be in agreement with the theoretical conception of SAD as a severity continuum and not as a circumscribed nosological entity.

There is little published literature on medical student exchanges in psychiatry.

To use a two-week student exchange between Modena, Italy and Norwich, UK to highlight some of the meaningful differences in psychiatric practice between the centers.

White coats - English doctors in general and especially psychiatrists do not wear white coats; in Italy these are almost always worn. Psychiatric nurses in English hospitals likewise do not wear any uniform.

Locations of services - Italian acute psychiatric wards are sited in general hospitals; in England they are usually in a separate location.

Nursing role - Psychiatric nurses in English hospitals are required to play a significant role in decision making around patient care. For example, nurses make almost all decisions regarding admission to hospital. It is also common for nurses to challenge doctors on decisions regarding patient treatments. The role of nurses in Italy is often not a decision-making one, but rather following doctors' orders and providing information.

Wearing white coats can promote a sense of professionalism and help orient patients in a hospital environment, but without these the ward may look less like a hospital and be more comfortable for patients.

Locating psychiatric wards within general hospitals makes consultation between specialties straightforward and may help reduce stigma, but psychiatry-only hospitals may create opportunities for economic efficiencies and improved facilities.

Enhanced nursing roles may be perceived as a possible threat by psychiatrists, yet may strengthen mental health teams and enhance quality of care.

There is a little of awareness about the existence of different methods for teaching undergraduate psychiatry in European countries.

To compare two methods of teaching psychiatry through a medical student's eyes during a student exchange.

Comparison of personal experience with traditional education at Modena (Modena University, Italy) and experience with Problem Based Learning (PBL) classes and didactic teaching in Norwich (UEA - Norwich,UK).

Group size- The traditional education system prefers lectures: one professor usually teaches more than 100 students. The PBL model assigns one tutor per group of 10 students. Intensity of work during the year - The traditional education system requires efforts to be concentrated on exams since clinical sessions and lessons can be attended passively. The PBL course requires that each student produce written work and teach this to the other group members weekly. Skill development- Facing comprehensive oral exams forces students in traditional education to focus learning sources and time. The PBL approach enhances debating abilities and improves skills in team working.

Professors' role- Traditional education professors are usually highly qualified in their subject. PBL professors do not necessarily have to be specialists in the subject because their role is mostly as supervisors of the peer-group learning process.

Although at the moment there is no evidence that interactive education methods are more effective in changing doctors' performance it is undeniable that PBL based courses offers more experience in teamwork and in working with a wide range of different colleagues.

While there is suggestion that early onset of psychosis is a determinant of outcome; knowledge regarding correlates of later onset age is more limited. This study explores the characteristics of patients developing psychosis after age 26, towards the end of the usual age range of early intervention programs, in order to identify potential specific needs of such patients.

Two hundred and fifty-six early psychosis patients aged 18–35 were followed-up prospectively over 36 months. Patients with onset after 26 (“later onset”, LO) were compared to the rest of the sample.

LO patients (32% of the sample) had shorter DUP, were less likely to be male, had better premorbid functioning and were more likely to have been exposed to trauma. They had greater insight at presentation and less negative symptoms overall. The trajectories for positive and depressive symptoms were similar in both groups. Evolution of functional level was similar in both groups, but while LO patients recovered faster, they were significantly less likely to return to premorbid functional level.

Later psychosis onset correlates with better premorbid functioning and higher rate of trauma exposure; the latter should therefore be a treatment focus in such patients. LO patients were less likely to return to premorbid functional level, which suggests that current treatment strategies may not be efficient to help patients maintain employment. The possibility of distinct illness mechanisms according to onset age and the more central role for trauma in patients with onset after age 26 needs to be further explored.

Postgraduate medical trainees experience high rates of burnout, but evidence regarding psychiatric trainees is missing. We aim to determine burnout rates among psychiatric trainees, and identify individual, educational and work-related factors associated with severe burnout.

In an online survey psychiatric trainees from 22 countries were asked to complete the Maslach Burnout Inventory (MBI-GS) and provide information on individual, educational and work-related parameters. Linear mixed models were used to predict the MBI-GS scores, and a generalized linear mixed model to predict severe burnout.

This is the largest study on burnout and training conditions among psychiatric trainees to date. Complete data were obtained from 1980 out of 7625 approached trainees (26%; range 17.8–65.6%). Participants were 31.9 (SD 5.3) years old with 2.8 (SD 1.9) years of training. Severe burnout was found in 726 (36.7%) trainees. The risk was higher for trainees who were younger (P < 0.001), without children (P = 0.010), and had not opted for psychiatry as a first career choice (P = 0.043). After adjustment for socio-demographic characteristics, years in training and country differences in burnout, severe burnout remained associated with long working hours (P < 0.001), lack of supervision (P < 0.001), and not having regular time to rest (P = 0.001). Main findings were replicated in a sensitivity analysis with countries with response rate above 50%.

Besides previously described risk factors such as working hours and younger age, this is the first evidence of negative influence of lack of supervision and not opting for psychiatry as a first career choice on trainees’ burnout.

Although the onset of bipolar disorder (BD) is usually estimated in early adulthood (Burke et al., 1990; Kessler et al., 1997), it is still not clear which age-specific triggering factors may contribute to the underlying vulnerability.

The present meta-analysis attempts to clarify the number of untreated years of BD, from first symptoms appearance, to first actions carried out by health services (first diagnosis, treatment and hospitalization).

A literature search of three databases PubMed, Web of Science and Psychology and Behavioral Sciences Collection was performed, looking for peer-reviewed publications in English, French, German and Italian language that reported the AOO of BD; the search string adopted was “bipolar and onset”. Standardized mean differences were calculated between (i) mean AOO, operationally defined as onset of first symptoms/episodes, and (ii) mean AOO, operationally defined according to four criteria: first contact with services, date of the diagnosis, first pharmacological treatment, or first hospitalization.

The searches yielded 8710 articles; 2424 of these articles met the inclusion criteria. A final set of 19 studies presenting multiple definitions of AOO has been analyzed, revealing an overall effect size of 6.96 of untreated years (Cohen's d = 0.65)

To our knowledge, this is the first meta-analysis that addresses the definition and the modulation of the AOO in bipolar disorder. Identifying the time-frame of untreated illness is very important for the best planning of timely interventions.
