Understanding the movement ecology of threatened species is fundamental to improving management and conservation actions for their protection, mainly during the pre-adult stage and particularly when a species is subject to population reinforcement or reintroduction projects. An example is the case of the Cinereous Vulture Aegypius monachus on the Iberian Peninsula, an endangered species that has been reintroduced in different regions during the last two decades. Here, we explore differences between the spatial ecology of reintroduced pre-adult Cinereous Vultures, according to age-class, sex, and season (breeding and non-breeding). We used GPS-tag data from 51 pre-adult individuals reintroduced into Catalonia (north-east Spain) to describe their use of space, i.e. home-range size, core area, and minimum convex polygon (MCP) and movement patterns, i.e. cumulative distance, maximum displacement, maximum daily dispersal, and maximum annual dispersal. Our study showed significant variation in the use of space and movement patterns among pre-adult birds and the influences of age, sex, and season. Age was the most influential factor, determining range areas and movement patterns. Similar to other vulture species, home range and core areas increase with age, with subadult vultures exhibiting larger ranges than young first year, juveniles, and immature birds, but the MCP measures were larger for juveniles. Movement patterns were also influenced by age-class, with juveniles making longer movements, followed by immatures and subadults (with similar values), and shorter movements for birds during their first year of life. Overall, males made shorter movements and explored smaller foraging areas than females. Season had an important effect on movement patterns, and the daily and dispersal movements were longer during the breeding period (February–August). Our findings fill a knowledge gap regarding the dispersal behaviours of Cinereous Vultures, information that will enable the improvement of management and conservation decisions.

Summary
Research on creative problem solving has shown that the generation of new ideas and solutions can be impeded by existing ideas and solutions. This phenomenon, known as mental fixation, has been observed in many problem-solving contexts, including the remote associates test (RAT). In the RAT, participants are presented with three cue words and are asked to come up with a fourth word related to each of the cue words. The task can be made more difficult by exposing participants to unhelpful associates that cause mental fixation before they attempt to generate the fourth word. The current chapter reviews research on the mechanisms by which people overcome the effects of mental fixation, focusing on research using the RAT, and on the potential roles of forgetting and inhibition. The results suggest that, at least under certain conditions, the ability to forget, inhibit retrieval, or stop a response can help people overcome mental fixation and thus lead to the experience of creative insight.

Human empathy towards non-human animals (Animal Empathy; AE) has shown a strong gender bias, with women demonstrating higher levels than men. This study aimed to investigate the influence of animal experiences on AE in a male-only sample. It was hypothesised that there would be different levels of AE between men with experiences caring for pets, men with experience in animal agriculture, and men with limited animal experiences. Ninety-one Australian men (18yrs+) completed an online survey evaluating their level of AE using the Animal Empathy Scale (AES). Additionally, they were asked what in their experience they think has influenced their beliefs about how animals think and feel. As expected, AE levels differed significantly between groups, with those in the pet ownership experience group demonstrating higher AE levels than the other two groups. All three groups displayed high endorsement for direct interactions with animals in adulthood as being most influential in shaping their beliefs about how animals think and feel. However, our quantitative results support the idea that not all experiences are worth the same, with the responsibility and sacrifice involved in pet caring appearing to be most influential to the development of AE. These findings have implications for the importance of human-animal interactions in understanding animal sentience and the development of AE in males.

Summary
By the year 1000 the Andalusian caliphate constituted a highly urbanized society, where the largest cities in Europe were located, while the economy of the Christian kingdoms of Iberia was characterized by a low level of urbanization and a poor market development. Five hundred years later, the territory of al-Andalus had disappeared and its economy had been absorbed and transformed into the Christian kingdoms. The latter’s territorial expansion was marked by the growth of cities, the impact of trade on the agrarian economy and an increase in rural stratification that, at different levels, made the market important for the satisfaction of needs and peasant consumption. In the Christian kingdoms, a strong increase in noble spending, emulated by urban elites, dedicated to the conspicuous consumption of products partially purchased on the international market, occurred throughout the period. After the Black Death, with the consolidation of a rural elite, important sectors of the population were attracted by the lifestyle of the urban elites. This evolution can also be detectable in the lifestyle of vast sectors of the population, in the cities as well as in the rural areas.

Like other animals, fish have unique personalities that can affect their cognition and responses to environmental stressors. These individual personality differences are often referred to as “behavioural syndromes” or “stress coping styles” and can include personality traits such as boldness, shyness, aggression, exploration, locomotor activity, and sociability. For example, bolder or proactive fish may be more likely to take risks and present lower hypothalamo–pituitary–adrenal/interrenal axis reactivity as compared to shy or reactive individuals. Likewise, learning and memory differ between fish personalities. Reactive or shy individuals tend to have faster learning and better association recall with aversive stimuli, while proactive or bold individuals tend to learn more quickly when presented with appetitive incentives. However, the influence of personality on cognitive processes other than cognitive achievement in fish has been scarcely explored. Cognitive bias tests have been employed to investigate the interplay between emotion and cognition in both humans and animals. Fish present cognitive bias processes (CBP) in which fish’s interpretation of stimuli could be influenced by its current emotional state and open to environmental modulation. However, no study in fish has explored whether CBP, like in other species, can be interpreted as long-lasting traits and whether other individual characteristics may explain its variation. We hold the perspective that CBP could serve as a vulnerability factor for the onset, persistence, and recurrence of stress-related disorders. Therefore, studying fish’s CBP as a state or trait and its interactions with individual variations may be valuable in future efforts to enhance our understanding of anxiety and stress neurobiology in animal models and humans.

Health systems are integrating medical-legal partnerships (MLPs) into clinical care and increasingly center “complex care” patients. These patients have intersecting medical and social needs and often face systemic inequities that exacerbate their chronic health conditions. This paper describes a role for MLPs in hospital quality initiatives; examines the ethics of MLPs assisting with guardianship and institutionalization of hospital patients including marginalized groups; and advocates for MLP interventions designed to address intersectional and ethical concerns.

Summary
This volume, part of the Feminist Judgment Series, shows how feminist legal theory along with critical race theory and intersectional modes of critique might transform immigration law. Here, a diverse collection of scholars and lawyers bring critical feminist, race and intersectional insights to Supreme Court opinions that deal with the source of the power to regulate immigration, state and local regulation of immigration, citizenship law, racial discrimination, employment law, access to public education, the rights of criminal defendants, the detention of noncitizens, and more. Feminist reasoning values the perspectives of outsiders, exposes the deep-rooted bias in the legal opinions of courts, and illuminates the effects of ostensibly neutral policies that create and maintain oppression and hierarchy. One by one, the chapters in this book reimagine the norms that drive immigration policies and practices. In place of discrimination and subordination, the authors here demand welcome and equality. Where current law omits the voice and stories of noncitizens, the authors here center their lives and experiences. Collectively, they reveal how a feminist vision of immigration law could center a commitment to equality and justice and foster a country where diverse newcomers readily flourish with dignity.

People with bipolar disorder (BD) often present emotion dysregulation (ED), a pattern of emotional expression interfering with goal-directed behavior. ED is a transdiagnostic construct, and it is unclear whether it manifests itself similarly in other conditions, such as major depressive disorder (MDD) or borderline personality disorder (BPD), or has specific features in BD. The present systematic review and meta-analysis explored ED and adopted emotion regulation (ER) strategies in BD compared with other psychiatric conditions. PubMed/MEDLINE, EMBASE, Scopus, and PsycINFO databases were systematically searched from inception to April 28th, 2022. Studies implementing validated instruments assessing ED or ER strategies in BD and other psychiatric disorders were reviewed, and meta-analyses were conducted. Twenty-nine studies yielding multiple comparisons were included. BD was compared to MDD in 20 studies (n = 2451), to BPD in six studies (n = 1001), to attention deficit hyperactivity disorder in three studies (n = 232), to anxiety disorders in two studies (n = 320), to schizophrenia in one study (n = 223), and to post-traumatic stress disorder in one study (n = 31). BD patients did not differ from MDD patients in adopting most adaptive and maladaptive ER strategies. However, small-to-moderate differences in positive rumination and risk-taking behaviors were observed. In contrast, patients with BPD presented an overall higher degree of ED and more maladaptive ER strategies. There were insufficient data for a meta-analytic comparison with other psychiatric disorders. The present report further supports the idea that ED is a transdiagnostic construct spanning a continuum across different psychiatric disorders, outlining specific clinical features that could represent potential therapeutic targets.

Gramsch and Lay [8] gave spectral mapping theorems for the Dunford-Taylor calculus of a closed linear operator $T$,
\[ \widetilde{\sigma}_i(f(T)) = f(\widetilde{\sigma}_i(T)), \]for several extended essential spectra $\widetilde {\sigma }_i$. In this work, we extend such theorems for the regularized functional calculus introduced by Haase [10, 11] assuming suitable conditions on $f$. At the same time, we answer in the positive a question made by Haase [11, Remark 5.4] regarding the conditions on $f$ which are sufficient to obtain the spectral mapping theorem for the usual extended spectrum $\widetilde \sigma$. We use the model case of bisectorial-like operators, although the proofs presented here are generic, and are valid for similar functional calculi.

The wetlands of the jalca ecoregion in the Andes of northern Peru form peat and play a major role in the hydrological ecosystem services of the ecoregion. Although peat is globally valued for carbon sequestration and storage, peatlands have not yet been mapped in the jalca. In this region, the Gocta waterfall, one of the 20 highest waterfalls in the world, depends on the jalca’s wetlands ecosystem. The local population depends on tourism to the waterfall and is concerned about preserving its drainage area. To inform conservation planning, in this study we delimited the drainage area of the Gocta waterfall and identified land tenure by applying Geographic Information System (GIS), remote sensing and participatory mapping techniques. Then, by classifying optical, radar and digital elevation models data, we mapped peatland in the jalca of the Gocta drainage area with an overall accuracy of 97.1%. Our results will inform conservation strategy in this complex area of communal, private and informal land tenure systems. At a regional level, this appears to be the first attempt at mapping peatlands using remote sensing imagery in the jalca ecoregion, and it represents a milestone for future efforts to map and conserve peatlands in other tropical mountain areas of the world.

This study examined the incorporation of benzalkonium chloride into palygorskite and montmorillonite, assessing their potential as drug carriers. The aim was to evaluate the use of both clay minerals as viable options for antibacterial drug delivery. Various amounts (0.5, 1.0 and 2.0 times the cation-exchange capacity) of benzalkonium chloride were incorporated into both clay minerals, and the resulting materials were characterized using Fourier-transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction and elemental analysis using both CHNS-O elemental analysis and energy-dispersive X-ray spectroscopy. The Fourier-transform infrared spectroscopy and elemental analysis results indicate that benzalkonium chloride was incorporated successfully into the clay minerals. The X-ray diffraction traces of organo-montmorillonite indicate that the d-value increased as benzalkonium chloride content increased, confirming the intercalation of benzalkonium chloride within the montmorillonite interlayer space. By contrast, this behaviour was not observed for palygorskite. For the benzalkonium chloride-release studies, an initial burst release was found within the first 5 h, followed by a sustained release of benzalkonium chloride during the remaining testing time (24 h). Drug-release profiles were similar for modified palygorskite or montmorillonite during the testing time (24 h). Both clay minerals modified with benzalkonium chloride are promising materials for use as antibacterial fillers for several applications, including in the dental care industry.

Introduction
Psychotic disorders carry several economical, psychological and social consequences, both at individual and community levels. Early intervention programs after first-episode psychosis which combine pharmacological and psychosocial strategies are aimed at reducing symptoms, lowering costs in the use of health and non-health care resources and improving overall functioning. AGES-Mind study is based on manualized psychotherapeutic interventions for people with first-psychosis episodes.
ObjectivesThe aim of the study was to evaluate the effect of a group psychotherapeutic intervention on the clinical status and use of clinical resources in a sample of patients with first-episode psychosis at 12 and 24 months after the beginning of the intervention. This cohort will be compared to patients with first-psychosis episodes without group psychotherapeutic intervention.
MethodsLongitudinal, observational, retrospective study on a cohort of N=46 patients with first-episode psychosis within the last 5 years. Two groups of 23 patients each were formed. The participants of one of those groups received group psychotherapy in the context of the AGES-Mind study and the other group received treatment as usual without group intervention. Non-exposed patients were matched by age, gender and time elapsed since first-episode psychosis with those exposed to the intervention. Sociodemographic data, clinical status and use of clinical resources outcome variables were assessed.
ResultsNo significant differences were found in clinical status and use of resources between participants and non-participants in the psychotherapeutic group intervention after 12 and 24 months.
ConclusionsAfter controlling for potentially confounding variables as sociodemographic, age and time since first-episode, participating in a group psychotherapeutic program does not seem to improve clinical variables or use of resources. Further studies with larger samples would be necessary to explore other variables, such as symptoms, satisfaction with the intervention or social functioning.

Introduction
Early intervention on a first psychotic episode is fundamental for a more favorable prognosis, and it usually combines pharmacological treatment, which mainly affects positive psychotic symptoms, with interventions that can improve the rest of the symptoms and associated problems such as deterioration in social functioning (Harvey & Penn, 2010; Fusar-Poli, McGorry & Kane, 2017). While Mindfulness is gaining more and more prominence in the field of psychotherapy (Chan et al., 2019; Cillesen et al., 2019), social cognition and social functioning are being researched as key targets on which to intervene after a first psychotic episode (Green, Horan & Lee, 2015).
SocialMIND® is a mindfulness-based social cognition training tailor-made to improve social functioning in people who have suffered a first psychotic episode within the last five years. It is currently being compared with a group Psychoeducational Multicomponent Intervention (PMI) in a Randomized Controlled Trial (RCT) (Mediavilla et al., 2019). Both group psychotherapies include 17 sessions delivered over a 9 month period: 8 weekly sessions, 4 biweekly sessions and 5 monthly sessions.
The results of SocialMIND® at 8 weeks showed improvements in social cognition and social functioning, specifically on affective social cognition and self-care (Mediavilla et al., 2021).
ObjectivesTo evaluate the efficacy of SocialMIND® in improving social functioning, measured by the Personal and Social Functioning (PSP) scale 16 weeks after starting the intervention, in people who have suffered a first psychotic episode in the last 5 years.
MethodsRandomized, controlled pilot trial (use of a psychoeducational multicomponent intervention or PMI as active comparator) of two parallel groups (SocialMIND® and PMI) with a 1:1 ratio using a blind evaluator.
ResultsNo statistically significant differences were found in the social functioning variable between the two treatment arms. Intragroup differences are observed in other secondary variables studied (social cognition) 16 weeks after starting the interventions.
ConclusionsSocialMIND® has not been shown to be more effective than a PMI in improving social functioning at 16 weeks after starting the intervention in people who have suffered a first psychotic episode in the five years prior to being included in the study.

Introduction
Many studies have investigated whether there exist predictors of good response to antimanic drugs in bipolar disorder (BD). However, these factors predict response or only indicate benign illness course.
ObjectivesTo shed some light on the topic, we tested whether the response to antimanic drugs showed any variability beyond that expected by the effects of illness course and placebo.
MethodsWe included all double-blind, placebo-controlled RCTs of oral pharmacotherapies targeting adult patients with acute bipolar mania from 1991 to 2020. The primary outcome was the variance of the improvement in manic symptoms in treated individuals compared to placebo. The effect size was the log variability ratio (logVR). We performed a random-effects meta-analysis, including assessments of heterogeneity, sensitivity/cumulative/subgroup analyses, and meta-regression.
Results42 RCTs (46 comparisons) from a total of 8,438 BD patients with acute mania (53.7% male, mean age=39.3; 5,563 treatment/2,875 control groups) were included in the analysis. Individuals in active treatment groups did not show variability in the response beyond that observed in individuals under placebo (VR=1; 95% C.I.=0.97,1.03; p-value=0.97). No heterogeneity was detected between the studies (I2=0%; tau2=0%; Q=29.21; df=45; p-value=0.97). Results were similar in the leave-one-out/cumulative/subgroup analyses. Meta-regression did not show influences by age, sample size, sex, severity of manic symptoms at baseline, or clinical features (rapid cycling, mixed or psychotic features).
ConclusionsThis meta-analysis shows no evidence of differences in the individual response to treatments. These findings suggest that the average treatment effect is a reasonable assumption for the individual BD patient with acute mania. The presented article adds evidence to the equivalent results in schizophrenia-spectrum disorders, clinical high-risk state for psychosis, and major depressive disorder, not supporting classification in responders vs. non-responders. However, these findings should be balanced with results from other fields supporting such classification.

Introduction
Emotion dysregulation (ED) is a multidimensional construct involving the lack of awareness, understanding and acceptance of emotions, a reduced access to adaptive and appropriate strategies to modulate the intensity or duration of emotional responses, and the inability to control behaviors in accordance with desired goals when experiencing negative emotions. ED is outlined in the general population and several psychiatric disorders, including bipolar disorder (BD), and influences its clinical course and management, quality of life, and daily social functioning.
ObjectivesThe objective of this systematic review was to examine the correlations between maladaptive (i.e., positive and negative rumination, negative focus, risk taking behaviors, suppression, and dampening) and adaptive (i.e., cognitive reframing, adaptive coping, and acceptance) strategies of emotion regulation (ER) and depressive and manic symptoms of BD.
MethodsWe searched the literature from inception to April 12, 2022, and included studies focusing on ER/ED assessed with a validated scale. We conducted multiple pairwise meta-analyses for correlations between ED dimension (or overall ED) and the measures of depressive and manic symptoms of BD, and separate Bayesian network meta-analyses to examine which aspects of emotion regulation were most closely associated with depressive and manic symptoms of BD. The Pearson’s r coefficients were adjusted using sample-size weights and Fisher’s r-to-z transformed was conducted.
ResultsA total of 13,826 records was identified and, after duplicate removal and title/abstract evaluation, 442 were explored at the full text. Sixteen studies were finally included. Results from pairwise meta-analyses are shown in Figure 1, results from network meta-analyses in Figure 2 and 3. Both depressive and manic BD symptomatology were found to be related to maladaptive ER strategies, with the only difference of positive rumination, associated only to manic symptoms. Negative rumination and risk-taking behaviors were the strategies more correlated to both manic and depressive symptoms, as confirmed by both pairwise metanalyses and network metanalyses. On the other hand, depressive symptomatology appeared more correlated with decreased adaptive strategies than manic symptomatology.

ConclusionsED has a significant correlation with BD symptomatology, therefore it should be explicitly considered during clinical assessment, diagnosis, and intervention on BD, and specific treatments should be implemented. More studies, and with longitudinal design, are needed to better explore these associations and their causal direction. In addition, future studies should mainly focus on the complex interactions between cognitive, social, and cultural aspects, and biological correlates to improve knowledge on a topic that is still poorly investigated.

Introduction
Emotion regulation (ER) is the ability to assess, monitor, or modify emotional reactions to achieve a goal (Gross. Psychological inquiry 2015; 26 1-26). When ER strategies are rigidly or maladaptively applied, emotional dysregulation (ED) can occur (Thompson. Development and psychopathology 2019; 31 805-815). ED is common in people diagnosed with bipolar disorder (BD), but it can also be described in other clinical populations given its transdiagnostic nature. Numerous aspects of ED have been described in BD (De Prisco et al. Neuroscience & Biobehavioral Reviews 2022; 104914), but it is unclear whether these manifest similarly in other conditions such as major depressive disorder (MDD) or borderline personality disorder (BPD), or whether they are specific to BD.
ObjectivesThe objective of this systematic review and meta-analysis is to examine the literature comparing BD with other psychiatric disorders in terms of ED, focusing on those studies using validated clinical tools.
MethodsA systematic search from inception to April 28th, 2022, was conducted exploring the PubMed/MEDLINE,EMBASE, Scopus, and PsycINFO databases. Those studies providing quantitative data on ED in people diagnosed with BD and compared with clinical groups were eligible for inclusion. No restriction about age, sample size, or language were applied. Random effect meta-analyses were conducted, and effect sizes were calculated as standardized mean differences (SMD).
ResultsA total of 3,239 records was identified and, after duplicate removal and title/abstract evaluation, 112 were explored at the full text. Twenty-nine studies were finally included, and it was possible to perform a meta-analysis with twenty-two (145 comparisons) of them. Only studies comparing BD with MDD, and BPD provided sufficient data to perform a meta-analysis. People with BD did not differ from people with MDD in most of the comparisons considered. However, BD patients presented higher positive rumination (two comparisons: SMD=0.46; CI=0.27, 0.64; p=8.5e-07; I2=0%; and SMD=0.34; CI=0.15, 0.52; p=2.7e-04; I2=0%) and risk-taking behaviors (SMD=0.48; CI=0.27, 0.69; p=8.11e-06; I2=0%). In contrast, people with BPD displayed an overall higher degree of ED (SMD=-1.22; CI=-1.94, -0.5; p=9.1e-04; I2= 90.7) and used fewer adaptive ER strategies. Additionally, higher levels of self-blaming (SMD=-0.80; CI=-1.11, -0.50; p=2.68e-07; I2=0) and impulsive behavior (SMD=-0.76; CI=-0.89, -0.63; p=5.4e-29; I2=0) were observed.

ConclusionsED is a trans-diagnostic construct that spans a continuum of different psychiatric disorders. Outlining the specific clinical features of one disorder versus another may help future research to increase our knowledge of these issues and develop new treatment strategies to reduce the clinical burden of these patients.

Introduction
Superior mesenteric artery syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta and the overlying superior mesenteric artery. This rare, potentially life-threatening syndrome is typically caused by an angle of 6°–25° between the abdominal aorta and the superior mesenteric artery, in comparison to the normal range of 38°–56°, due to a lack of retroperitoneal and visceral fat (mesenteric fat). In addition, the aortomesenteric distance is 2–8 millimeters, as opposed to the typical 10–20. However, a narrow superior mesenteric artery angle alone is not enough to make a diagnosis with no symptoms.
Symptoms are fullness and epigastric tightness after meals, nausea and vomiting (often bilious) and pain in the middle of the abdomen that improves with the prone or knees flexed to the chest. The diagnosis is supported by imaging tests (esophagogastroduodenal transit or CT) showing dilation and stasis proximal to AMS in the third duodenal portion.
Relief from vomiting with feeding through a enteral probe placed beyond the obstruction to the proximal jejunum supports diagnosis.
Precipitating factors should be corrected first, whenever possible. Acute symptoms can be resolved with gastric decompression and intravenous fluids. Therefore, surgical correction should only be done in well-studied patients with chronic recurrent episodes of AMS syndrome. The most recommended surgical technique is a laparoscopic proximal duodenojejunostomy
ObjectivesTo describe a case of superior mesenteric artery syndrome and review in literature the organic complications and associated psychopathology of this disorder
MethodsClinical case report and brief review of literatura
Results17-year-old woman with a diagnosis of anorexia nervosa. Admitted for behavioral disorder, repeated self-harm and low mood. Presents a BMI of 16.6. Irregular rules. Progressive diet is started to which nutritional supplements are added with good initial tolerance. It presents a loss of 2kg and begins with nausea, vomiting and postprandial epigastralgia. Oral panendoscopy and abdominal ultrasound are performed showing possible mesenteric aortic clamp so naso-jejunal probe and exclusive enteral feeding is prescribed. She received enteral jejunal nutrition progressively with feedback syndrome prophylaxis that included parenteral vitamin B1. After a few days, oral supplementation began. He remained hemodynamically stable, with no signs of heart failure. It gained 3kg of weight up to 43.2kg, starting before discharge from the hospital successfully oral tolerance.
ConclusionsSuperior mesenteric artery syndrome is a serious complication in anorexia nervosa with a low incidence and an estimated mortality of 33%. A multidisplinar approach that addresses both the medical and psychological needs of these patients throughout their hospital stay is necessary.

Introduction
Psychotic disorders have a huge impact on social functioning, which is the ability to stablish and maintain social activities such as interpersonal relationships and self-care activities of daily living. Research data support that the early intervention in people who have experienced a first episode of psychosis (FEP) -based on a multidisciplinary treatment including both psychopharmacological and psychosocial treatments-, has a relevant role in a favorable evolution. AGES-Mind study is based on manualized psychotherapeutic interventions for people with first-psychosis episodes.
ObjectivesTo describe the use of rehabilitation resources and social functioning in a group of people with FEP who were included in a psychotherapeutic group program versus a control group, at 12 and 24 months since the beginning of the intervention.
MethodsLongitudinal, analytical, observational, retrospective study on a cohort of 46 patients with first-episode psychosis within the last 5 years. 23 patients received group psychotherapy in the context of the AGES-Mind study and they were compared with 23 control patients who did not receive a group intervention (treatment as usual). Controls were matched by age, gender and time elapsed since the first episode of psychosis with those exposed to the intervention. Sociodemographic data, social functioning (self-care, social activities, social relationships, and behavior) and use of rehabilitation resources outcome variables were assessed.
ResultsSignificant differences were found regarding participation in social activities in the intervention group versus control group at 24 months. No significant differences were found in other dimensions of social functioning or in the use of rehabilitation resources.

ConclusionsFurther studies with larger sample sizes are needed in order to determine if the participation in group therapy leads to an improvement in social functioning and use of rehabilitation resources for people who have experienced a first episode of psychosis.

Introduction
The intentional use of drugs before or during sexual intercourse (chemsex) is a phenomenon of special importance in the MSM (men who have sex with men) population due to its impact on mental, physical and sexual health.
ObjectivesThe objective of this study was to compare the psychopathological characteristics between users whith sexualized intravenous substance use (slamsex) versus those who did not slamsex attended by the non-govenrmental organization Apoyo Positivo in the program “Sex, Drugs and You”.
MethodsA cross-sectional descriptive analysis of a sample of users attended by the non-govenrmental organization Apoyo Positivo in the program “Sex, Drugs and You” was performed.
Results230 participants were included. Slam was associated with higher risk of having and anxiety or depressive disorder, suicidal ideation, induced psychosis and suicidal behavior, the differences were statistically significant (p<0.05) in all cases.
ConclusionsSlamsex is usually reported in our sample. Substance use disorders in slam users are usually associated with other mental disorders. This challenge requires adapt the therapeutical interventions of the professionals who work with patients with chemsex practices, specially with those who practice slamsex.

Introduction
We present a case of a 15 year-old boy diagnosed with Unspecified Personality and Beheavioral Disorder Due to Brain Damage from a Human Herpes Virus-6 Encephalitis.
ObjectivesTo describe a case of an Unspecified Organic Personality and Behavioral Disorder secondary to brain damage from Human Herpes Virus-6 (HHV-6) Encephalitis in an 11 year-old childand to review recent literature, in order to improve clinical practice.
MethodsClinical case report and brief review of literature. A bibliographic research was made in the database PubMed, using the terms “Viral Encephalitis” AND “Neuropsychiatric symptoms”; “Viral Encephalitis” AND “Behavioral Disorder”; “Long-Term Neurological Morbidity” AND “Viral Encephalitis”.
Results15 year-old boy diagnosed with Unspecified Personality and Beheavioral Disorder Due to Brain Damage from a Human Herpes Virus-6 Encephalitis, secondary to immunosupression in the context of haematopoietic progenitor transplantation (HPT) at 11 years old. MRI showed supratentorial ventriculomegaly, atrophic changes in encephalon and right hippocampus with subcortical retraction secondary to previous encephalitis. Clinically, main changes appeared in behavior, presenting a serious frontal syndrome with high disinhibition, what implied severe social and academic difficulties. During the outpatient follow-up, the behavioural disorder is being pharmacologically treated with Risperidone 1,5mg per day with a partially favorable evolution. The patient presented intolerance to olanzapine, with an episode of low level of conciuosness after taking it.
Bibliographic research results indicate that the gold standard treatment for behavioral disturbances are antipsychotics. Risperdidone is proven save for treatment in children. Results point out also the importance of an early multidisciplinar intervention, involving family training, rehabilitation resources and curricular adaptations.

ConclusionsViral encephalitis may have serious neuropsychiatric consequences, especially during childhood while the brain development is not finished. When the neurological damage affects the frontal lobes of the brain, behavioural and personality disturbances are expected and an early multidisciplinar intervention should be considered. Antypsichotics are the gold standard pharmacological treatment for behavioural disturbances. During the scholar period, special curricular adaptations should be done in order to reduce study-related stress.
