The study assessed the interactions and the impact of specialist mobile community care teams (assertive outreach teams or AOTs) implemented in the mental health (MH) system of Bizkaia (Spain) using a methodology derived from an ecosystem perspective.
Methods
First, the experts assessed the system’s services and codified them according to an international classification system. Second, following an iterative methodology for expert-knowledge elicitation, a clients’ flow diagram showing the inter-dependencies of the system’s components was developed. It included variables and their relationships represented in a causal model. Third, the system elements where the AOTs had a major impact (stress nodes) were identified. Fourth, three scenarios (variable combinations representing the ‘stress points’ of the system) were modelled to assess its relative technical efficiency (technical performance indicator).
Results
The classification system identified the lack of fidelity of the AOTs to the original assertive community treatment model, categorizing them as non-acute low-intensity mobile care. The causal model identified the following elements of the system as ‘stress nodes’ in relation to AOT: users’ families; social services (outside of the healthcare system); acute hospitals; non-acute residential facilities and, to a lesser extent, acute hospital day care services. When the stress nodes inside the healthcare system were modelled separately, acute and non-acute hospital care services resulted in a large deterioration in the system performance, while acute day hospital care had only a small impact.
Conclusions
The development of the expert-knowledge-based causal model from an ecosystem perspective was helpful in combining information from different levels, from nano to macro, to identify the components in the system likely to be most affected by a potential policy intervention, such as the closure of AOTs. It was also able to illustrate the interaction between the MH system components over time and the impact of the potential changes on the technical performance of the system. Such approaches have potential future application in assisting with service planning and decision-making in other health systems and socio-economic contexts.
The concept of “Recovery” in the context of psychiatric rehabilitation has undergone significant evolution throughout history. This abstract delves into the question of the truth or falsity of this concept, examining diverse perspectives and arguments surrounding its application.
Objectives
The primary aim of this abstract is to critically analyze the concept of “Recovery” in psychiatric rehabilitation and ACT from both favorable and critical perspectives, considering its historical evolution, and highlighting key distinctions between the theories of Mike Slade and William Anthony.
Furthermore, it addresses the significance of measuring and evaluating the fidelity of healthcare practices to this mode
Methods
To conduct this analysis, an exhaustive review of current scientific literature was undertaken. Emphasis was placed on the importance of measuring and evaluating the fidelity of healthcare practices to this model.
Results
Slade and Anthony’s theories emphasize different aspects of recovery, while implementation models translate these theories into clinical practice and services. Additionally, the discussion highlights the significance of measuring and evaluating the fidelity of healthcare practices to this model.
Assertive Community Treatment (ACT) programs have increasingly recognized the importance of the “recovery” concept in promoting the empowerment and self-determination of individuals with severe mental illnesses. This discussion examines how ACT programs have adopted recovery-oriented principles, the ways in which they implement these principles, and the potential benefits and challenges associated with their integration.
Conclusions
The distinctions between Mike Slade and William Anthony’s theories and the implementation models underscore the importance of a precise and differentiated understanding within the field of psychiatric rehabilitation.
The integration of the “recovery” concept within Assertive Community Treatment (ACT) represents a significant shift towards person-centered care in psychiatric rehabilitation. Further research and evaluation are essential to assess the effectiveness and long-term impact of this integration.

Obesity is highly prevalent and disabling, especially in individuals with severe mental illness including bipolar disorders (BD). The brain is a target organ for both obesity and BD. Yet, we do not understand how cortical brain alterations in BD and obesity interact.
Methods:
We obtained body mass index (BMI) and MRI-derived regional cortical thickness, surface area from 1231 BD and 1601 control individuals from 13 countries within the ENIGMA-BD Working Group. We jointly modeled the statistical effects of BD and BMI on brain structure using mixed effects and tested for interaction and mediation. We also investigated the impact of medications on the BMI-related associations.
Results:
BMI and BD additively impacted the structure of many of the same brain regions. Both BMI and BD were negatively associated with cortical thickness, but not surface area. In most regions the number of jointly used psychiatric medication classes remained associated with lower cortical thickness when controlling for BMI. In a single region, fusiform gyrus, about a third of the negative association between number of jointly used psychiatric medications and cortical thickness was mediated by association between the number of medications and higher BMI.
Conclusions:
We confirmed consistent associations between higher BMI and lower cortical thickness, but not surface area, across the cerebral mantle, in regions which were also associated with BD. Higher BMI in people with BD indicated more pronounced brain alterations. BMI is important for understanding the neuroanatomical changes in BD and the effects of psychiatric medications on the brain.
The aim of this study was to investigate the psychometric properties of the Spanish version of the Stigma of Occupational Stress Scale for Doctors (SOSS-D) and the factors associated with Physician Burnout in Paraguay.
Methods:
Participants included 747 Paraguayan healthcare workers, aged 24–77 years old, of both sexes. SOSS-D was translated into Spanish and validated through an exploratory and confirmatory factor analysis. Participants were also scored with the Oldenburg Burnout Inventory (OLBI), the CAGE questionnaire, and the stigma subscale of the Perceived Barriers to Psychological Treatment (PBPT) measure.
Results:
Three factors had a raw eigenvalue greater than 1, and explained 61.7% of total variance. The confirmatory analysis confirmed that the scale is three-dimensional. The model adjustment was good, according to all fit indices. OLBI results indicate clinically significant disengagement in 85.9% and clinically significant exhaustion in 91.6% of participants. Of the 747 participants, 57.6% reported alcoholic beverage consumption and among those, 19.3% had problematic alcohol consumption according to the CAGE questionnaire. The correlation between SOSS-D and the stigma subscale of the PBPT was statistically significant (r = 0.245, p < 0.001).
Conclusions:
The Spanish version of the SOSS-D was found to have good psychometric properties and adequately reproduces the three-dimensional model of the original English version.
Family studies provide the opportunity to investigate endophenotypes as a powerful neurobiological platform to better understand the underlying neurobiological mechanisms of schizophrenia spectrum disorders. Shared features between the patients and their first-degree relatives may shed some light on the path to identify potential causes of psychosis, and to implement preventive and therapeutic interventions.
Objectives
This study aimed to explore and compare neuropsychological measures in first episodes of psychosis (FEP) patients, their first-degree relatives and healthy controls (HC), participants on the PAFIP-FAMILIES project.
Methods
Statistical analyses were performed using one-way ANOVA, followed by multiple comparisons test where appropriate. Age, sex and years of education were introduced as covariates.
Results
From 387 eligible FEP patients enrolled in a previous cohort, 133 were included. In addition, 244 of their first-degree relatives (146 parents and 98 siblings) and 202 HC participated in this study (see Figure 1). In general, relatives showed an intermediate neuropsychological performance between the HC and the FEP patients (see Figure 2). Specifically, siblings performed similar to HC in the domains verbal memory, visual memory, working memory, motor dexterity and theory of mind, since their values practically overlap those of HC. The parents presented significant deficits, similar to that of the affected individuals, in executive functions and attention domains.
Conclusions
These findings suggest that executive and attention dysfunction might have a greater family aggregation and could be a relevant cognitive endophenotype for psychotic disorders. The study shows the potential of exploring intra-family neuropsychological performance supporting neurobiological and genetic research in schizophrenia.
The Intensity Interferometry technique consists of measuring the spatial coherence (visibility) of an object via its intensity fluctuations over a sufficient range of telescope separations (baselines). This allows us to study the size, shape and morphology of stars with an unprecedented resolution. Cherenkov telescopes have a set of characteristics that coincidentally allow for Intensity Interferometry observations: very large reflective surfaces, sensitivity to individual photons, temporal resolution of nanoseconds and the fact that they come in groups of several telescopes. In the recent years, the MAGIC Collaboration has developed a deadtime-free Intensity Interferometry setup for its two 17 m diameter Cherenkov telescopes that includes a 4-channel GPU-based real-time correlator, 410–430 nm filters and new ways of splitting its primary mirrors into submirrors using Active Mirror Control (AMC). With this setup, MAGIC can operate as a long-baseline optical interferometer in the baseline range 40–90 m, which translates into angular resolutions of 0.5-1 mas. Additionally, thanks to its AMC, it can simultaneously measure the zero-baseline correlation or, by splitting into submirrors, access shorter baselines under 17 m in multiple u-v plane orientations. The best candidates to observe with this technique are relatively small and bright stars, in other words, massive stars (O, B and A types). We will present the science cases that are currently being proposed for this setup, as well as the prospects for the future of the system and technique, like the possibility of large-scale implementation with CTA.
The aim of this study is to test the psychometric properties of the Spanish validation of the Fear of COVID-19 Scale (FCV-19S) in a Paraguayan population.
Methods:
Participants were recruited through an Internet-based survey. All participants whose scores in the Hospital Anxiety and Depression Scale (HADS) and The Fear Questionnaire (FQ) were greater than zero were included. 1245 subjects responded voluntarily: 1077 subjects, scoring >0, were considered.
Results:
To establish construct validity of the FCV-19S, an exploratory factor analysis was performed using the KMO test, which was adequate, and the Bartlett sphericity test, which was significant (p <.0001). The CFI, NFI, GFI, TLI and RMSEA indices were used to evaluate the model and showed good adjustment. Cronbach’s α showed valid internal consistency (α = 0.86). This validation was supported by significant correlation (p <.001) with the HADS scale for anxiety and depression and with the FQ scale for specific phobia.
Conclusions:
The Spanish version of the FCV-19S is a 7-item scale with two dimensions, psychological symptoms and physiological symptoms, which demonstrated robust psychometric properties in a Paraguayan population.
This project will work closely with existing service partners involved in street level services and focus on testing and evaluating three approaches for street level interventions for youth who are homeless and who have severe or moderate mentally illness. Youth will be asked to choose their preferred service approach:
Housing First related initiatives focused on interventions designed to move youth to appropriate and available housing and ongoing housing supports.
Treatment First initiatives to provide Mental Health/Addiction supports and treatment solutions, and; Simultaneous attention to both Housing and Treatment Together
Our primary objective is to understand the service delivery preferences of homeless youth and understand the outcomes of these choices. Our research questions include:
1. Which approaches to service are chosen by youth?
2. What are the differences and similarities between groups choosing each approach?
3. What are the critical ingredients needed to effectively implement services for homeless youth from the perspectives of youth, families and service providers?
Focus groups with staff and family members will occur to assist in understanding the nature of each of service approach, changes that evolve within services, & facilitators and barriers to service delivery. This work will be important in determining which approach is chosen by youth and why. Evaluating the outcomes with each choice will provide valuable information about outcomes for the service options chosen by youth. This assist in better identifying weaknesses in the services offered and inform further development of treatment options that youth will accept.
Psychedelic drugs were used extensively in psychotherapy in the 1950s to lower psychological defences and facilitate emotional insight. Thousands of research participants were administered hallucinogens in the context of basic clinical research or therapeutic clinical research, resulting in hundreds of publications. Results across studies were ultimately inconclusive due to such variations in methods and a lack of modern controls and experimental rigour. The growing controversy and sensationalism resulted in increasing restrictions on access to hallucinogens throughout the 1960s (ultimately resulting in the placement of the most popular hallucinogens into Schedule I of the 1970 Controlled Substances Act in the United States).
Aims
Renewed human administration research began in the 1990s. Recent clinical studies have administered hallucinogens to evaluate their safety and efficacy in the treatment of psychiatric disorders: specifically, anxiety related to advanced-stage cancer (Grob, 2005), obsessive-compulsive disorder (Moreno, et al., 2006), heroin dependence (Krupitsky, et al., 2007), personal meaning and spiritual significance (Griffiths, et al., 2008), and a meta-analysis of randomized controlled trials of LSD for alcoholism (Krebs,et al., 2012).
Results
Psychedelic-assisted psychotherapy utilizes the acute psychological effects of psychedelic drugs to enhance the normal mechanisms of psychotherapy. The effects of psychedelic psychotherapy are often very pronounced within several days or weeks after a treatment session, but then these effects quickly decline. This phenomenon was termed a “psychedelic afterglow”.
Conclusions
Fhurther research, blinded, randomized, placebo-controlled, methodology should explore the efficacy of hallucinogens.
Recently, a renaissance of interest in ‘negative symptoms’ as emotional withdrawal or blunted affect, has occurred. Some investigators believe that these symptoms are important indicators of outcome, of response to treatment and of a distinct underlying pathologic process.
Research on the negative-symptom syndrome in schizophrenia has been handicapped until recently.
Aims:
This research aims at studying whether acute phase proteins, precisely, Alpha1-glycoprotein, can be considered as a marker of negativesymptom in Schizophrenia.
Methods:
29 chronic schizophrenics were assessed by the Positive and Negative Syndrome Scale (PANSS). A routine blood test including Alpha1-glycoprotein levels was carried out.
Results:
Alpha1-glycoprotein shows a positive correlation, according to Pearson correlation coefficient, with the Negative Scale at an almost significant level (p=.05), and at a significant level in the following items, Blunted affect (p=.03), Passive/apathetic Social Withdrawal (p=.01) of the Negative spectrum and Poor Attention (p=.02) of the General Psychopathology Scale.
Conclusions:
There is a significant correlation with two Negative variables and an almost significant one, spite of the small sample, with the Negative Scale. Further studies with bigger samples are needed in order to consider alpha1-glycoprotein as a schizophrenia negative psychopathology marker.
Tuberous Sclerosis Complex (TSC) is a genetic inherited disease characterized by hamartomatous growths in several organs as brain, skin, kidneys, hearth and eyes. The estimated incidence is approximately 1:6000 live births. The diagnosis is made clinically. Seizures are present in 87% of patients. Psychiatric comorbidity has been reported.
Objectives:
We report the clinical course of two patients with previous diagnosis of TSC. Psychiatric symptoms start in the adulthood without seizures history and absence of Subependimal Giant Cells Tumor (SGCT). The evolution and clinical features are described.
Methods:
Patient 1
Married 33-years-old woman with two children affected with TSC. She was diagnosed after headache presentation in 2011. Initial MRI showed periventricular glioneuronal hamartomas. In January 2013 start with self-injurious (swallowing of objects) and autistic behaviours as well as several hospital urgency room visits. In addition, the patient presented with dull mood, emotional indifference and intellectual impairment, with no response to medication.
Patient 2
Married 43-years-old woman with a daughter affected with TSC. Diagnosis was made in 1999 and psychotic symptoms (delusional beliefs and auditory hallucinations) started in 2011 without previous psychiatric history. The MRI in 2013 shown subependymal nodules. Treatment with risperidone was effective.
Results:
Psychiatric symptoms are very often associated to the physical findings on TSC, even in adulthood diagnoses.
Conclusions:
Psychiatric comorbidities are well described in literature. about 10-20% adult patients with TSC present clinically significant behavioral problems as self-injuries, frequently associated with SGCT. The European Expert Panel recommended regular assessment of cognitive development and behaviour and symptomatic treatment.
Dysthymia is defined as a chronic mood disorder that persists for at least two years in adults, and one year in adolescents and children. It is important to distinguish it from other types of depression, as early as possible. The therapeutic management of dysthymia is similar to the one used in major depressive disorder.
Objectives
We report the case of a female patient aged 45, diagnosed with depressive disorder not otherwise specified since she was 20. Her psychopathological progress has gradually become aggravated, having now longer periods of depressive mood and an important tendency towards isolation.
Methodology
The patient is admitted to the Psychiatric Day Hospital presenting with important depressive symptoms. After various antidepressants were withdrawn, lithium salts were introduced. It is then that the patient starts improving her mood.
Results
– Dysthymia (F34.1).
– Mixed and other personality disorders (F61.0).
Conclusions
In spite of having an appropriate pharmacological, unfortunately, antidepressants improve dysthymia just in 50–70% of patients. Antidepressants resistant dysthymia cases have been studied. In those cases, it has been necessary to add lithium or thyroxine. This confirms that, when it comes to this disorder, there are many neurochemical mechanisms involved, given the positive response to the combination of drugs, notwithstanding the severity of the adverse effects.

Opioids are the most powerful drugs commercialised for acute and chronic pain relief. The main emerging problem in our midst is the abuse and addiction to synthetic opioids iatrogenically established in general population.
Objectives
We report the case of a female patient aged 48 admitted to the Acute Psychiatric Unit after a suicide attempt. She refers she finds herself more irritable and depressed since she began a treatment with oxycodone after she was diagnosed with fibromyalgia. She has lost a lot of weight, is not able to get to sleep and has become socially isolated.
Methodology
During the first few days, the patient is uncooperative and shows a marked self-referentiality and verbalises delusional ideation related to her immediate surroundings. Once the treatment with opioids was withdrawn and we had prescribed paliperidone ER, she seemed more cooperative and calmed. She was discharged from the Psychiatric Day Hospital showing a good evolution.
Results
Paranoid personality disorder (F60); mental and behavioural disorders due to use of opioids (F11); recurrent depressive disorder, current episode moderate (F33.1); fibromyalgia (M79.7).
Conclusions
The use of synthetic opioids (tramadol, fentanyl, oxycodone) in easy-to-use formats (patches, pills, dispersible tablets, lollipops) and their dissemination in pain treatment, is leading to an increase of problems related to it, both their side effects (psychotic symptoms) and the generation of misuse and addiction. We should pay greater attention to the prescription of opioids to patients with dysfunctional personality traits.

To assess the prescription of benzodiazepines (BZD) in elderly patients, and to explore any gender differences.
Methods
Six hundred and fifty-four patients (≥ 65) admitted in an emergency service of a general hospital due to a fall. BZD use information was collected (dose, half-life profile).
Results
BZD are significantly more prescribed to women (47.6%) than men (36.1%) (X2 = 8.097, P = 0.004). We conducted a logistic regression analysis using as dependent variable taking or not BZD and sex as the independent one, covariating the model by age. We noted that sex remains significant despite enter the age variable in the model (OR = 1.5, P = 0.013). A total of 21.6% of patients consumed intermediate or long half-life BZDs, appearing a greater tendency to prescribe such BZD to women (X2 = 3.606, P = 0.058). In the 58.0% of prescriptions, prescribed dose was higher than the recommended for the elderly. The percentage is significantly higher for men (70.0%) than women (53.1%). Furthermore, a total of 54 prescriptions (15.8%) were even higher than the recommended adult dose, with no significant differences between men and women.
Conclusions
We found evidence of a higher prescription of BZD in women independently of age. Despite not being recommended, prescription of intermediate or long half-life BZD continues, in a slightly higher manner in women. BZD are prescribed above the recommended dose for elderly in a large number of patients, especially in men. A considerable proportion of elderly patients (15.8%) consume BZD doses even higher than the recommended for adults.

Although both obesity and ageing are risk factors for cognitive impairment, there is no evidence in Chile on how obesity levels are associated with cognitive function. Therefore, the aim of the present study was to investigate the association between adiposity levels and cognitive impairment in older Chilean adults. This cross-sectional study includes 1384 participants, over 60 years of age, from the Chilean National Health Survey 2009–2010. Cognitive impairment was evaluated using the Mini-Mental State Examination. BMI and waist circumference (WC) were used as measures of adiposity. Compared with people with a normal BMI, the odds of cognitive impairment were higher in participants who were underweight (OR 4·44; 95 % CI 2·43, 6·45; P < 0·0001), overweight (OR 1·86; 95 % CI 1·06, 2·66; P = 0·031) and obese (OR 2·26; 95 % CI 1·31, 3·21; P = 0·003). The associations were robust after adjustment for confounding variables. Similar results were observed for WC. Low and high levels of adiposity are associated with an increased likelihood of cognitive impairment in older adults in Chile.
We study the behaviour of the dynamical and stellar mass inside the effective radius as function of local density for early-type galaxies (ETGs). We use several samples of ETGs - ranging from 19000 to 98000 objects - from the ninth data release of the Sloan Digital Sky Survey. We consider Newtonian dynamics, different light profiles and different initial mass functions (IMF) to calculate the dynamical and stellar mass. We assume that any difference between these two masses is due to dark matter and/or a non-universal IMF. The main results are: (i) the amount of dark matter (DM) inside ETGs depends on the environment; (ii) ETGs in low-density environments span a wider DM range than ETGs in dense environments; (iii) the amount of DM inside ETGs in the most dense environments will be less than approximately 55-65 per cent of the dynamical mass; (iv) the accurate value of this upper limit depends on the impact of the IMF on the stellar mass estimation.
The purpose of this paper was to prepare purified Na- bentonite with improved properties for use in the pharmaceutical industry. Calcium bentonite from the Shagia region of Karak district, Pakistan, was activated with various proportions of sodium carbonate (2, 3, 5 and 8 wt.%) and purified by sedimentation to remove impurities, especially quartz. X-ray diffraction (XRD), and swelling volume confirmed the conversion of raw bentonite to sodium bentonite by using 5% Na2CO3. The sodium bentonite (K5) obtained by activation met the chemical and microbiological requirements set by the pharmacopeias regarding the toxic trace elemental content (Pb and As), absence of E. coli, total aerobic microbial contents and physicochemical properties such as swelling volume, pH and sedimentation volume. Therefore K5 bentonite could be designated as potentially suitable for pharmaceutical applications. The CEC, surface area, porosity, pH, gel formation and swelling volume indicated that K5 bentonite could be used in the formulation of oral suspension and in topical application.
The Radiocarbon Laboratory of the Universidade Federal Fluminense, in Brazil, has been successfully applying the zinc reduction method for graphitization of carbon samples since the development of its early protocols in 2009. Successive methodological research aiming to improve and, ultimately, optimize the precision and accuracy of our results indicates that graphitization temperatures as low as 460°C promote erratic 13C isotopic fractionation, but an approximately constant fractionation of about –5‰ is achieved at 520°C. In this work, we present isotope ratio mass spectrometry (IRMS) δ13C results for 14C reference materials graphitized at 550°C with variable amounts of zinc. Based on the results obtained from the addition of 20, 35, and 50 mg of zinc, we conclude that a slightly lower variation in 13C isotope fractionation during graphitization is obtained with less zinc. Moreover, the average isotopic fractionation is not altered by increasing the graphitization temperature from 520°C to 550°C.
A new final fish host (Stromateus brasiliensis) for the digenean parasite Monascus filiformis from the continental shelf of Patagonia Argentina in the South-western Atlantic Ocean is reported. This demersal-pelagic fish (commonly denominated pampanito) is exclusively a jellyfish consumer. It is well known that larval stages of Monascus filiformis mostly use medusae as secondary hosts. Therefore, the pampanito likely acquires this parasite when it predates upon some species of parasitized medusae in the area. This work improves the knowledge about the final hosts of this parasite and infers which species of medusa may be involved in their life cycle.
