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.

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.

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.

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).

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.

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.

Determine the relationship between inflammatory/neural plasticity markers and cognitive functioning in MDD patients and healthy controls.

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.

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.

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%.

To describe a case of Psychosis produced by Levetirazetam

Retrospective review of clinical records and complementary test, including psychiatry, electrophysiology and neurology. Diagnosis schales such as Salamanca Questionnaire were used as suport.

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

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.

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.

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.

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).

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.

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.

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.

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).

Cognitive reserve and neurocognition are related to functioning, and social cognition mediates in this relationship.

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.

1. - Establish clinical-socio-demographic profile and risk factors for psychotic people with autolytic behaviors.

2. - Determine frequency of suicides in psychotic disorders in our area of care.

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.

1. - The sample includes 191 patients:41(21%) have attempted suicide.

2. - 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.

3. - 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).

:

1. - 21% of hospitalized psychotic patients have presented some autolytic attempt.

2. - 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.

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.

Retrospective study(13-month) of patients admitted to UPD of Leon Hospital from its inception to date. Data are collected from medical histories.

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.

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.

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.

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).

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.

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.

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.

Plasma concentrations of endocannabinoids and congeners will be analyzed in 69 patients with depression from primary care and 47 controls using mass spectrometry analysis.

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.

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.

The objective of this work is to characterize the plasma levels of endocannabinoids and congeners in a sample of patients with bipolar disorders.

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).

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.

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.

To describe the clinical and therapeutic management of inpatients admitted to Leganés National Asylum between 1900 and 1931.

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.

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.

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.

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.

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.

– Dysthymia (F34.1).

– Mixed and other personality disorders (F61.0).

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.

To describe the sociodemographic and hospitalization characteristics of the patients who were admitted to Leganés National Asylum between 1900 and 1931.

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.

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.

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.

The aim of the present study was to evaluate the interactions between mephedrone and ethanol in humans.

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).

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.

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.

Despite multiple clinical and preclinical studies investigating schizophrenia, the neurobiological basis of this disease is still unknown. The dysregulation of the serotonergic system, in particular the 5-HT2A receptor and the endocannabinoid system have been postulated as possible causes of schizophrenia.

The aim of this study is to evaluate the expression of CB1-5-HT2A receptor heteromers in primary cultures of pro-neurons from the olfactory epithelium in schizophrenia patients and control subjects.

We recruited a group of 10 healthy volunteers and 10 patients diagnosed with schizophrenia, who were treated with atypical antipsychotics, were clinically stable and had an illness duration range from 1 up to 15 years. The patients were diagnosed with schizophrenia from the medical record and confirmed by the structured clinical interview for DSM disorders. The expression of CB1-5-HT2A receptor heteromers in primary cultures of pro-neurons from the olfactory epithelium was quantified using proximity ligation assays and confocal microscopy.

Olfactory epithelium pro-neurons were viable and expressed the neuronal marker, III-β tubulin. We also established the presence and the functionality of CB1-5-HT2A receptor heteromers in these cells using the proximity ligation and cAMP activity assays, respectively. Heteromer expression was significantly increased in schizophrenia patients with respect to controls.

This highly innovative methodology will allow the noninvasive, low-cost study of new biomarkers for schizophrenia in a model closely related to the central nervous system.
