The present paper proposes a hierarchical, multi-unidimensional two-parameter logistic item response theory (2PL-MUIRT) model extended for a large number of groups. The proposed model was motivated by a large-scale integrative data analysis (IDA) study which combined data (N = 24,336) from 24 independent alcohol intervention studies. IDA projects face unique challenges that are different from those encountered in individual studies, such as the need to establish a common scoring metric across studies and to handle missingness in the pooled data. To address these challenges, we developed a Markov chain Monte Carlo (MCMC) algorithm for a hierarchical 2PL-MUIRT model for multiple groups in which not only were the item parameters and latent traits estimated, but the means and covariance structures for multiple dimensions were also estimated across different groups. Compared to a few existing MCMC algorithms for multidimensional IRT models that constrain the item parameters to facilitate estimation of the covariance matrix, we adapted an MCMC algorithm so that we could directly estimate the correlation matrix for the anchor group without any constraints on the item parameters. The feasibility of the MCMC algorithm and the validity of the basic calibration procedure were examined using a simulation study. Results showed that model parameters could be adequately recovered, and estimated latent trait scores closely approximated true latent trait scores. The algorithm was then applied to analyze real data (69 items across 20 studies for 22,608 participants). The posterior predictive model check showed that the model fit all items well, and the correlations between the MCMC scores and original scores were overall quite high. An additional simulation study demonstrated robustness of the MCMC procedures in the context of the high proportion of missingness in data. The Bayesian hierarchical IRT model using the MCMC algorithms developed in the current study has the potential to be widely implemented for IDA studies or multi-site studies, and can be further refined to meet more complicated needs in applied research.
Suicide behaviour is a complex and multifactor concept that includes different risk factors. According with literature a dimensional concept of illness could help to understand this complexity and clarify clinical aspects of suicide risk.
Objectives
The aim of this study is to identify different profiles of symptoms in a sample of suicide attempters and the relationship between this profiles and suicide behaviour in terms of outcome: presence and intensity of suicidal ideation, presence and number of attempts and severity of the medical damage in the current attempt.
Methods
634 patients were recruited at the psychiatry emergency of eight public general hospitals in Spain between November 2020 until February 2022 in the SURVIVE protocol. The patients were assessed in 15 days using a battery of clinical tools that includes Brief Symptom Inventory, a sociodemographic interview, Mini Clinical Interview and C-SSRS, ACSS and BIS-11 scales. Latent profile analysis was applied to obtain profile symptoms. Logistic and multivariant regression was used to obtain data about outcome.
Results
Three clinical profiles of psychiatric symptoms were described in suicide attempters (p < 0.01): high symptoms (HS) (45.02%), moderate symptoms (MS) (42.5 %) and low symptoms (LS) (12.48%). Significant differences were found between classes in four symptom domains (Figure 1): anxiety, obsessive-compulsive, sensitivity, and somatization (p < 0.01). Participants of the HS class showed higher values in relation with the BSI summary indexes, and more diagnoses, higher levels of suicidal ideation and suicidal related behaviour as well as higher acquired capability for suicide. Participants of the LS class were more likely to be women, older and unemployed and was related, according the analysis, with severe medical damage when compared with other groups (P< 0.01).

Conclusions
According with the predictive model the study suggests different symptom-frequency clusters related with suicide attempt outcomes. Suicide ideation presence and intensity is related with HS class and acquired capability of suicide. Suicide ideation intensity is also related with number of diagnosis and number of previous attempts. Suicide behaviours presence is associated with being student and number with HS profile. Both presence and number were related with number of diagnosis as well as number of previous attempts (the higher all these clinical factors, the more intense of ideation in the last month). Finally, the severity of medical damage was related with LS profile and unemployed/retired work status. The dimensional symptom profile could be useful to predict suicide attempt outcome. Further study is needed to clarify this relation.
Migratory birds are implicated in dispersing haemosporidian parasites over great geographic distances. However, their role in sharing these vector-transmitted blood parasites with resident avian host species along their migration flyway is not well understood. We studied avian haemosporidian parasites in 10 localities where Chilean Elaenia, a long-distance Neotropical austral migrant species, spends part of its annual cycle to determine local parasite transmission among resident sympatric host species in the elaenia's distributional range across South America. We sampled 371 Chilean Elaenias and 1,818 birds representing 243 additional sympatric species from Brazilian wintering grounds to Argentinian breeding grounds. The 23 haemosporidian lineages found in Chilean Elaenias exhibited considerable variation in distribution, specialization, and turnover across the 10 avian communities in South America. Parasite lineage dissimilarity increased with geographic distance, and infection probability by Parahaemoproteus decreased in localities harbouring a more diverse haemosporidian fauna. Furthermore, blood smears from migrating Chilean Elaenias and local resident avian host species did not contain infective stages of Leucocytozoon, suggesting that transmission did not take place in the Brazilian stopover site. Our analyses confirm that this Neotropical austral migrant connects avian host communities and transports haemosporidian parasites along its distributional range in South America. However, the lack of transmissive stages at stopover site and the infrequent parasite lineage sharing between migratory host populations and residents at breeding and wintering grounds suggest that Chilean Elaenias do not play a significant role in dispersing haemosporidian parasites, nor do they influence local transmission across South America.
Inflammation and neural plasticity play a significant role in major depressive disorder (MDD) pathogenesis and cognitive dysfunction. The olfactory neuroepithelium (ON), closely related to the central nervous system (CNS), allows a non-invasive, low-cost study of neuropsychiatric disorders. However, few studies have used ON cells to ascertain them as biomarkers for MDD.
Objectives
Determine the relationship between inflammatory/neural plasticity markers and cognitive functioning in MDD patients and healthy controls.
Methods
Sample: 9 MDD patients and 7 healthy controls. Exclusion criteria: other Axis I mental disorders (patients) or any mental disorder (controls) and any inflammatory, autoimmune, or CNS diseases. Assessment: sociodemographic, clinical, and cognitive variables (CANTAB) were recorded. mRNA was isolated from ON cells and MAPK14, IL6, TNF-α, Mecp2, BDNF, GSK3, GRIA2, and FosB gene expression levels were quantified using quantitative polymerase chain reaction.
Results
MDD patients showed decreased levels of BDNF (p=0.022), GSK3 (p=0.027), and working memory (p=0.024) compared with healthy controls. In healthy controls, planning was positively correlated with NRF2, BDNF, and MAPK14 gene expression. In MDD patients no correlation between cognitive parameters and inflammation/neural plasticity biomarkers was found.
Conclusions
These results reveal that: (1) Plasticity biomarkers such as BDNF and GSK3 could be useful diagnostic tools for MDD (2) MDD is associated with working memory deficits; (3) no association could be determined between planning and NRF2, BDNF, and MAPK14 gene expression in MDD and (4) the ON is a promising model in the study of neuropsychiatric disorders.
Levetirazetam is an antiepileptic drug with psychiatric adverse reactions. It includes psychosis, paranoia or hallucinations. The frequency is less than 1%.
Objectives
To describe a case of Psychosis produced by Levetirazetam
Methods
Retrospective review of clinical records and complementary test, including psychiatry, electrophysiology and neurology. Diagnosis schales such as Salamanca Questionnaire were used as suport.
Results
A 42-year-old woman diagnosed with tuberous sclerosis and undergoing treatment with levetirazetam acudes to the emergency department for behavioral disorders. She has presented an episode of aggression against a relative threatening him with a kitchen knife. The family reports that since the change in antiepilepticus 1 month ago, the patient has presented strange behaviors. Te Patient is conscious, uncooperative. Barely Approachable. Suspicious of her surroundings, with psychomotor restlessness, self-reference ideas and sparse speech. Auditory hallucinations seem to be present, as well as depressed and irritable mood. Psychic and somatic anxiety is found.
Levetirazetam is discontinued, being replaced by valproic acid. Risperidone is started at a 3 mg dose. Treatment is well tolerated, and clinical stability is achived. Cluster A personality traits are found. Complementary test Blood and Urine simples, Imaging tests (CT and MRI), electroencephalogram and Electrocardiogram show no alterations
Conclusions
Levetirazetam can cause psychiatric adverse effects. it is important to make a proper diagnosis before a first psychotic outbreak in later life. Drugs that can produce psychiatric side effects should be identified and patients should be inform.
Neuroimaging findings have reported aberrant functional connectivity in brain regions involved reward system in individuals with anorexia nervosa (AN) altering hedonic processing over food. Likewise, endocannabinoids such as Anandamide (AEA) and 2-Arachidonoylglycerol (2-AG) have been involved in rewarding aspects of food intake.
Objectives
To identify nucleus accumbens (NAcc) functional connectivity with whole-brain comparing between individuals with AN and controls. Furthermore, in a sub-study, to explore the interaction between NAcc functional connectivity and peripheral AEA and 2-AG levels.
Methods
A total of 60 adult women (18 to 56 years of age) took part in the present study. Twenty-six individuals belonged to the AN group (BMI<18) and 34 to the HC group (BMI=18-24.99). All participants underwent functional magnetic resonance in resting-state, and blood samples were obtained in fasting.
Results
Negative functional connectivity was observed in the AN group compared with the control group between the NAcc and the cerebellum (pFWE<.001), between the NAcc and the insula (pFWE<.001), between the NAcc and the supramarginal gyrus (pFWE=.019), and between the NAcc and the postcentral gyrus (pFWE=.010). Analyses exploring the association between NAcc functional connectivity and peripheral endocannabinoids levels displayed altered NAcc-cerebellum functional connectivity was negatively associated with peripheral 2-AG levels in the AN group (r= -.553; p=.011).
Conclusions
Understanding the interaction between the reward system and peripheral endocannabinoids in patients with AN could contribute to better elucidate the pathophysiology of this disorder. Future studies will need to further investigate the clinical and therapeutic implications of these findings in patients with AN.
Social cognition has been associated with functional outcome in patients with first episode psychosis (FEP). Social cognition has also been associated with neurocognition and cognitive reserve. Although cognitive reserve, neurocognitive functioning, social cognition, and functional outcome are related, the direction of their associations is not clear.
Objectives
The aim of the study was to analyze the influence of social cognition as a mediator between cognitive reserve and cognitive domains on functioning in FEP both at baseline and at 2 years.
Methods
The sample of the study was composed of 282 FEP patients followed up for 2 years. To analyze whether social cognition mediates the influence of cognitive reserve and cognitive domains on functioning, a path analysis was performed. The statistical significance of any mediation effects was evaluated by bootstrap analysis.
Results
At baseline, as neither cognitive reserve nor the cognitive domains studied were related to functioning, the conditions for mediation were not satisfied. Nevertheless, at 2 years of follow-up, social cognition acted as a mediator between cognitive reserve and functioning. Likewise, social cognition was a mediator between verbal memory and functional outcome. The results of the bootstrap analysis confirmed these significant mediations (95% bootstrapped CI (−10.215 to −0.337) and (−4.731 to −0.605) respectively).
Conclusions
Cognitive reserve and neurocognition are related to functioning, and social cognition mediates in this relationship.

ABSTRACT IMPACT: Current practice guidelines offer a variety of treatment options for sternal reconstruction but complications and infections remain a serious surgical problem. This work seeks to provide a comprehensive picture of the com-morbidities and reconstructive methods that lead to success and improve patient outcomes. OBJECTIVES/GOALS: Patients that undergo cardiac surgery via the median sternotomy approach are at risk of wound complications that require repair. We seek to evaluate how outcomes of sternal reconstruction are influenced by patient comorbidities, flap usage and internal mammary artery grafts and methods of sternal closure. METHODS/STUDY POPULATION: We identified patients between 2005 and 2020 who underwent sternotomy followed by debridement and flap coverage at our institution. Comorbidities, method of reconstruction, demographic data, surgical history, and other factors pertaining to mortality and morbidity were collected. The data will then be analyzed to identify population characteristics using logistic regression variables to determine univariate and adjusted multivariable measures of association with mortality. We present the pre-liminary data analyzed using chi-square and one-way anova in R. RESULTS/ANTICIPATED RESULTS: In this study we present a preliminary characterization of one institution’s sternal reconstruction patient outcomes with a variety of reconstruction methods including pectoralis advancement flaps, omental flaps and latissumus dorsi flaps. Notable preoperative comorbidities include 50% of patients > age 60, 18% with diabetes mellitus, 18 % with diagnosed hypertension, 18% with COPD, and 9% with a smoking history DISCUSSION/SIGNIFICANCE OF FINDINGS: In an evolving cardiothoracic landscape, clinical characteristics of patients being treated for sternal reconstructive surgery present a moving target. Understanding current risk factors, preoperative management and timing for aggressive surgical treatment offers an opportunity to update treatment protocol and maximize successful outcomes.
Describe Attention Deficit Hyperactive Disorder's (ADHD) prevalence in Bipolar Disorders (BD) and relatives.
Methods
78 admissions for Bipolar Disorder (DSM-IV) in Impatient Psychiatric Unit, in Hospital Clínico Universitario of Valladolid (Spain). Only 36/78 patients participate in study. Demographic, social and clinical information were registered. ADHD symptomatology was evaluated from patient and descendant (Conners short version).
Results
ADHD symptomatology suggestive in childhood/adolescence were detected in 13,9% (5/36). Conners score were negative (below 15) in all case.
ADHD symptomatology suggestive in their children were detected in 6,25% (n=3). Conner score were positive in 2,1%. Family psychiatry history in 72,2% (n=26), affective disorder in 60,52% (n=23). No family history with ADHD diagnosis. Only one case (2,8%) with symptomatology suggestive of ADHD in relatives.
Conclusions
The ADHD prevalence in our sample of BD and relatives weren’t higher than general population.

Fiction films offer unexplored opportunities of rehabilitation for schizophrenia and other psychoses. Schizophrenia produces deficits y distortions in the perception and comprehension of reality, also expressed in the perception and comprehension of films. After a year of an “ad hoc” experience, the following technique was developed:
1) Selecting a fiction film for its narrative, affective, cognitive and social cognitive content
2) Briefly presenting of the film to a group of 8-16 patients with diverse psychosis.
3) Screening of the film to the patients and the therapeutic team.
4) Summarizing of the plot by a patient. Group correcting of distortions and deficits caused by problems of attention and working memory, as well as positive, negative, affective and social cognitive symptoms (emotional perception, theory of mind, attributive style)
5) Selecting 1-2 sequences by each patient, and group commenting using the same technique.
6) Field recording of all the commentaries obtained.
7) Second screening of the film two days after, repeating points 2 to 6.
8) Comparing both field records.
An experimental study using this technique is presented. 8 patients with schizophrenia and other psychoses watched 4 fiction films (“The 39 Steps”, “Charade”, “M”, “The General”). The differences founded in both viewings by two external evaluators (using CGI and analogical scales of the main variables) are presented and commented. An evaluation of the perceived usefulness and satisfaction of the participants was included.
Suicide is one of the most frequent causes of death. In 1993, Bleuler emphasized its importance in his “Suicidal behavior is the most serious symptom of schizophrenia”. Since then, various studies have confirmed importance of suicide in schizophrenia, and today it's clear that his research and knowledge is one of the great challenges of psychiatry.
Objectives
- Establish clinical-socio-demographic profile and risk factors for psychotic people with autolytic behaviors.
- Determine frequency of suicides in psychotic disorders in our area of care.
Material and methods
Retrospective study(3 years evolution) that includes psychotic patients(diagnosed according DSM IV-TR) admitted to the HCU of Valladolid. With data provided by hospital medical records, analyzed socio-demographic variables and clinics. Study consists of two groups:group of cases(those patients who have suicidal behavior) and control group (those that haven't autolytic gesture during the study period). Statistical evaluation was performed with SPSS.
Results
- The sample includes 191 patients:41(21%) have attempted suicide.
- Of them:73% are males;88% singles;51% have basic studies;61% we re unemployed;37% were 31-40 aged;54% started disease 21-30 aged and 63.5% are schizophrenic.
- Considering statistical study we find that suicidal patient profile is male(p = 0.039),diagnosed with schizophrenia(p = 0.033),with previous suicide attempts(p = 0.009)and lack of social support(p = 0.007).
Conclusions
:
- 21% of hospitalized psychotic patients have presented some autolytic attempt.
- Profile of suicidal psychotic patient is a male, single, 21-40 aged, primary education, unemployed, with a primary diagnosis of schizophrenia, particularly paranoid, with ten years evolution,without acceptable social support, number of revenues higher than non-suicidal psychotic and a personal history of previous autolytic attempts.
UPD is a regional referral hospital psychiatric care unit, endowed with multidisciplinary equipment. It provides care to people with light/moderate/severe intellectual incapacity coexisting with mental disease and/or severe behavioral disorders. It offers attention to patients who need a protected therapeutical environment for correcting behavior disorders. It was opened in September 2008.
Objectives
Description of:therapeutic goals, inclusion/exclusion criteria, admission protocol and psychotherapeutic/pharmacological interventions.
Analysis of inpatients's sociodemographic/clinical characteristics and preliminary assessment of therapy goals.
Methodology
Retrospective study(13-month) of patients admitted to UPD of Leon Hospital from its inception to date. Data are collected from medical histories.
Results
47 referrals have been received,5 of them have been rejected not to fulfill criteria. We’ve 16 patients on waiting list.32 incomes have been realized and 22 discharges have occurred.
19 of the incomes correspond to Mild,6 to Moderate,6 to Severe and 1 to Profound mental Retardation.
Regarding co-morbidity:22 patients presented serious behavioral disorder. From this group, 2 met criteria for autistic disorder, 5 had schizophrenia or unspecific psychotic disorders, 5 presented Personality Disorder and one ADHD.
10 patients did’nt present any important behavioral disturbance. From this group 2 were diagnosed with OCD,3 presented problems due to Alcohol and Substance-related Disorders,3 had Psychotic Disorders, one met criteria for Impulse Control Disorder and one presented Mood Disorder.
Before admission, 12 patients resided in specific handicappeds center, 5 intermittently at selected centers and in family, and 15 lived with family.
Conclusions
Psychotherapeutic intervention and treatment were useful in most cases. It was particularly helpful in treatment of behavioral disturbances. Now we must determine effectiveness in maintenance of improvement when they return to their community.
Neuropsychological and neuroimaging studies of response inhibition in cannabis users have reported inconsistent results. The age of onset of cannabis use and individual genetic differences may play a critical role in the regulation of inhibition in cannabis users.
Aims:
We examine the influence of COMT Val158Met functional polymorphism on the response inhibition brain network in a group of early-onset chronic cannabis users compared with healthy controls.
Methods:
fMRI data was acquired from 27 chronic cannabis users who began use cannabis before 16 years of age, and 29 non-using control subjects matched in terms of age, educational level and intelligence quotient while undergoing the Multi-Source Interference Task (MSIT). Participants were male, Caucasians aged between 18 and 30 years. All were assessed by a structured psychiatric interview (PRISM) to exclude any lifetime Axis-I disorder (DSM-IV). COMT genotyping was performed and resonance imaging data was analysed by voxel-based morphometry (VBM).
Results:
Both groups did not differ on their behavioural performance and brain responses during the MSIT task. A significant group-by-genotype interaction was observed on task-related brain activation (and on MSIT reaction times), in which met carrier load was associated with increased activation in cannabis users and val carrier load with increased activation in controls. The interaction pattern included the medial frontal cortex, ACC, inferior frontal gyrus, ventral striatum, anterior mesencephalon, inferior parietal and superior temporal cortices and the PCC.
Conclusion:
Chronic cannabis exposure interacts with the genetically driven dopamine function in the modulation of the neural mechanisms related to response inhibition.
Endocannabinoid system has been highlighted as one of the most relevant research topics by neurobiologists, pharmacists, basic scientists and clinicians. The association between endocannabinoids and its congeners and mood disorders is relatively recent. However, evidence from both clinical and preclinical studies is increasing and many researchers point out endocannabinoid system and particularly endocannabinoids and congeners as promising pharmacological targets.
Aims and objectives
The main objective of this study is to compare the plasma concentrations of endocannabinoids and congeners between a sample of patients with depression and a sample of control subjects, and the influence of variables such as age, body mass index, gender, severity of symptoms, and antidepressant medication.
Method
Plasma concentrations of endocannabinoids and congeners will be analyzed in 69 patients with depression from primary care and 47 controls using mass spectrometry analysis.
Results
Statistically significant differences in 2-arachidonoylglycerol and monoacylglycerols were found between both samples. Somatic symptoms of depression seems to be more related to these compounds that to cognitive-affective symptoms. In addition, differences between mildly and moderately depressed patients were found in concentrations of AEA, LEA, DGLEA and POEA. Patients with antidepressant medication showed higher levels of 2-AG, DGLEA and OEA.
Conclusions
The results of this study provide evidence supporting the hypothesis that in depression there is a dysregulation of the inflammatory signaling and, consequently the immune system. The results of this study could also support the realization of translational research to better understand the mechanisms of this widely distributed system.

Endocannabinoid System (ECS) has been highlighted as one of the most relevant research topics by neurobiologists, pharmacists, basic scientists and clinicians (Skaper and Di Marzo, 2012). Recent work has associated major depressive disorder with the ECS (Ashton and Moore, 2011). Despite the close relationship between depression and bipolar disorders, as far as we know, there is no characterization of ECS and congeners in a sample of patients with bipolar disorders.
Aims and objectives
The objective of this work is to characterize the plasma levels of endocannabinoids and congeners in a sample of patients with bipolar disorders.
Method
The clinical group was composed by 19 patients with a diagnosis of bipolar disorders using SCID-IV (First et al., 1999). The control group was formed by 18 relatives of first- or second-degree of the patients.
The following endocannabinoids and congeners were quantified: N-palmitoleoylethanolamide (POEA), N-palmitolylethanolamide (PEA), N-oleoylethanolamide (OEA), N-stearoylethanolamide (SEA), N-arachidonoylethanolamide (AEA), N-dihomo-γ-linolenoylethanolamide (DGLEA), N-docosatetraenoylethanolamide (DEA), N-linoleoylethanolamide (LEA), N-docosahexaenoylethanolamide (DHEA), 2-arachidonoylglycerol (2-AG), 2-linoleoylglycerol (2-LG), and 2-oleoylglycerol (2-OG).
Results
The result showed statistically significant lower levels of AEA, DEA and DHEA in clinical sample. Previous research also identified lower levels of AEA in depressed women (Hill et al., 2008, 2009). Until date, it is unknown if DEA and DHEA have some effect on EC receptors, and whether they have some direct effects on endocannabinoids.
Conclusions
It would be necessary to carry our other research with a larger sample, which could allow the control of potential confounding variables.

Leganés Psychiatric Hospital has been the subject of several studies about its institutional history and clinical activity. The first decades of the twentieth century are the less explored years; however, important events for the development and establishment of the discipline of psychiatry happened in Spain during this period.
Objectives/aims
To describe the clinical and therapeutic management of inpatients admitted to Leganés National Asylum between 1900 and 1931.
Material and methods
This is a retrospective case series study. We reviewed medical records found in the Historical Archives of Psychiatric Institute, Germany (n = 1043) of inpatients admitted between 1900 and 1931. We analyzed clinical care variables, mainly related to diagnosis and treatment, of the patients who were admitted during this period (n = 1043) with SPSS v21. We consulted bibliography, such as asylum documents and diverse primary and secondary literature.
Results
The diagnosis of mania was very common in the early twentieth century. Lypemania nearly disappeared after 1910 and monomania was not observed in any patient. Delusions decreased after 1905. The first patient diagnosed with schizophrenia was admitted on 19th November 1921. From that moment, the use of this term increased significantly. Only 4.4% of patients admitted underwent treatment.
Conclusions
We confirmed the predominance of French nosology in the early twentieth century. From 1920, an increase in German nosography was observed. The application of treatments was rare.

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.

Leganés Psychiatric Hospital has been the subject of several studies about its institutional history, clinical activity and demography of its institutionalized population. The first decades of the twentieth century are the less explored years; however, important events for the development and establishment of the discipline of psychiatry happened in Spain during this period.
Objectives/aims
To describe the sociodemographic and hospitalization characteristics of the patients who were admitted to Leganés National Asylum between 1900 and 1931.
Methods
This is a retrospective case series study. We reviewed medical records found in the Historical Archives of Psychiatric Institute Germain (n = 1043) of inpatients admitted between 1900 and 1931. We analyzed sociodemographic and hospitalization related variables of medical records with SPSS v21. We consultedbibliography, such as asylum documents and diverse primary and secondary literature.
Results
Most inpatients were male, single, with an average age of 38 years, came from home and were admitted as fee-paying boarders. Circa 64% of them remained in the institution until death and the average stay was 7.92 years.
Conclusions
Even though the Leganés Asylum was born amidst debate on the asylum model, it did not meet the expectations. Among other reasons, it presented serious architectural deficiencies and was unable to classify inpatients according to the French tradition (agitated, dirty, quiet) or to separate populations, such as minors or criminal inpatients, thus becoming a charity institution asylum instead of a therapeutic mental hospital.

Mephedrone is a synthetic cathinone derivative included in the class of “New-Novel Psychoactive Substances”. Synthetic cathinones are marketed as “bath salts” or “plant food” and gained notable popularity for similar effects to 4-methylenedioxymethamphetamine (MDMA, ecstasy), or amphetamines. Mephedrone is commonly consumed simultaneously with alcohol.
Objectives and aims
The aim of the present study was to evaluate the interactions between mephedrone and ethanol in humans.
Methods
Twelve healthy male, recreational users of psychostimulants participated as outpatients in four experimental sessions. They received a single oral dose of mephedrone (200 mg) and alcohol (0.8 g/kg), mephedrone placebo and alcohol (0.8 g/kg), mephedrone (200 mg) and placebo alcohol, and both placebos. Design was double-blind, double-dummy, randomized, cross-over and controlled with placebo. Study variables included: vital signs (blood pressure, heart rate, temperature, and pupil diameter), subjective effects (visual analogue scales-VAS, ARCI-49 item short form, and VESSPA questionnaire).
Results
The combination produced an increase in the cardiovascular effects of mephedrone and induced more intense feeling of euphoria and well-being in comparison to mephedrone and alcohol. Mephedrone reduced the drunkenness and sedation produced by alcohol.
Conclusions
These results are similar to those obtained with the combination of other psychostimulants as amphetamines and MDMA. Abuse liability of the combination is greater that induced by mephedrone.
