Cannabis use and familial vulnerability to psychosis have been associated with social cognition deficits. This study examined the potential relationship between cannabis use and cognitive biases underlying social cognition and functioning in patients with first episode psychosis (FEP), their siblings, and controls.

We analyzed a sample of 543 participants with FEP, 203 siblings, and 1168 controls from the EU-GEI study using a correlational design. We used logistic regression analyses to examine the influence of clinical group, lifetime cannabis use frequency, and potency of cannabis use on cognitive biases, accounting for demographic and cognitive variables.

FEP patients showed increased odds of facial recognition processing (FRP) deficits (OR = 1.642, CI 1.123–2.402) relative to controls but not of speech illusions (SI) or jumping to conclusions (JTC) bias, with no statistically significant differences relative to siblings. Daily and occasional lifetime cannabis use were associated with decreased odds of SI (OR = 0.605, CI 0.368–0.997 and OR = 0.646, CI 0.457–0.913 respectively) and JTC bias (OR = 0.625, CI 0.422–0.925 and OR = 0.602, CI 0.460–0.787 respectively) compared with lifetime abstinence, but not with FRP deficits, in the whole sample. Within the cannabis user group, low-potency cannabis use was associated with increased odds of SI (OR = 1.829, CI 1.297–2.578, FRP deficits (OR = 1.393, CI 1.031–1.882, and JTC (OR = 1.661, CI 1.271–2.171) relative to high-potency cannabis use, with comparable effects in the three clinical groups.

Our findings suggest increased odds of cognitive biases in FEP patients who have never used cannabis and in low-potency users. Future studies should elucidate this association and its potential implications.

An increased risk of suicide has been reported by psychiatric patients, including schizophrenia1. Numerous evidence suggests alterations in the grade of pro-inflammatory impact on suicidal behavior2, and this relation has been shown in patients with mood or anxious disorders3,4. However, the grade of inflammation impact suicidal behavior in patients with schizophrenia has hardly been investigated.

Identify peripheral blood biomarkers of suicidal behavior in patients with schizophrenia, including inflammatory and lipid profile parameters.

Secondary analysis of a cross-sectional study. Sample: 254 patients with schizophrenia, aged 18-72. Assessments: ad-hoc demographic and clinical questionnaire, PANSS, CDS, CAINS, PSP. Inflammatory and lipid parameters: C-reactive protein (PCR), interleukin 6 (IL-6); high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceridaemia (TG). Statistical analysis: Correlations, T Student, U Mann-Withney and lineal regression.

Mean age: 40.49 (13.10). Men: 64.2%.

No statistically significant differences were found between patients with suicide attempts and those without in any of the inflammatory or lipid parameters (p>0.05). However, differences were found in terms of suicide attempts (yes/no) in the PANSS negative (T=-2.217; p=0.028) and PANSS general psychopathy (T=-4.224; p< 0.001), in depressive symptoms (T =-6.967; p< 0.001), and the MAP subscale of the CAINS (T= -3.741; p<0.001).

Among patients with suicide attempts (n=42; 16.52% of the sample) (mean=1.90; sd=1.73; Range:1-7), statistically significant correlations were found with PCR (r=0.309; p=0.046), but not with cytokines and lipid parameters. On the other hand, no correlations were found with age, sex, length of illness, and any of the clinical scales.

A multiple linear regression was performed considering the number of suicide attempts as the dependent variable and as independent variables, age, sex, and those that were significant in the bivariate analysis (PCR).

A predictive model was found that explains 9.60% of the variance of number of suicide attempts (F = 4.224; p < 0.001). The variable that entered the model was PCR (β= 0.309; p=0.046).

The increase in inflammation (manifested by the elevation of PCR) is related to an increase in the number of suicides. On the contrary, no correlations were found with lipid parameters or interleukins.

Short-chain fatty acids (SCFA) are bacterial metabolites that, within microbiome-gut-brain axis, make a promising research line on etiopathology of mental diseases like schizophrenia (SZ) and major depression disorder. Besides, depressive symptoms are frequent clinical features of SZ.

• - Describe fecal SCFA concentrations in SZ patients.

• - Analyze differences in SCFA depending on:

• - Depression.

• - Clinical severity, antipsychotics and antidepressants, comorbidities (pro-inflammatory state/obesity/metabolic syndrome [MetS]), lifestyle.

Cross-sectional study of 67 outpatients [mean age=43.52±12.42, range=22-67; males=40 (59.7%)] with diagnosis (DSM-5) of SZ recruited from their mental health clinics in Oviedo (Spain).

• - Assessment:

• - Fecal SCFA (gas chromatography;μg/mL).

• - Plasmatic C-reactive protein (CPR;mg/dL).

• - PANSS, Calgary Depression (CDS), International Physical Activity (IPAQ), Mediterranean Diet Adherence (MEDAS).

• - Toxic habits (alcohol use/smoking/cannabis).

• - Chlorpromazine equivalent doses (CPZ-ED), use of antidepressants.

• - MetS (ATP-III), body mass index (BMI; kg/cm2).

• - Statistics: Spearman correlation, U Mann-Whitney, ANCOVA.

14 patients showed clinical depression (CDS≥5). There were no differences in age or sex between groups. 36 patients (53.7%) showed systemic low-grade inflammation (CPR≥0.3mg/dL) and 32 (30.8%) MetS.Table 1 shows fecal SCFA levels by depressive state. Means (SD) are ahown.Table 1

Correlations were found in Age with Butyrate (r=-0.248,p=0.043) and weekly alcohol units with Propanoate (r=0.250,p=0.041) plus trend to significance with Butyrate (r=0.232,p=0.059). It also showed a trend towards statistical relation for CPZ-ED with Propanoate (r=-0.253,p=0.039) and Total SCFA (r=-0.253,p=0.039). We found no correlation in SCFA with MetS, CGI, PANSS-N, BMI, IPAQ, MEDAS and other toxic habits.

ANCOVA was performed to Acetate and Total SCFA using depression state as independent variable and Age and CPZ-ED as covariates. There was a trend towards statistical significance for Acetate (F=3.937,p=0.052,η2=0.059) whereas Total SCFA showed no difference (F=1.350,p=2.250,η2=0.021).

There seems to be lower levels of fecal Acetate in SZ patients with depressive symptoms, considering age and antipsychotic intake. In our sample there was no relation between SFCA and clinical severity, lifestyle, comorbidities or antidepressant use.

There is a growing interest in understanding the impact of duty hours and resting times on training outcomes and the well-being of resident physicians. Psychiatry resident’s duty hours in Spain comprise a regular working schedule of 37.5h per week and a minimum of 4 mandatory on-call shifts. The most recent duty hours regulations in Spain were transposed from the European Working Time Directive (EWTD). According to Spanish Law, doctors cannot work for more than 48h per week and need to have resting times per day (at least 12h), per week (at least 36h) as well as annual leave (at least a month). However, there is practically no data on this situation in psychiatry resident physicians.

Our aim is firstly, to describe the number of shifts performed by psychiatry resident physicians in Spain. Secondly, to describe compliance with the daily and weekly rests compared to those set in national and European law. Finally, to analyse the difference by demographic variables (gender and year of residency), in both the number of on-call duty shifts and compliance with rests.

A descriptive cross-sectional study was designed through an online survey adapted from the existing literature. The target population were Spanish psychiatry resident physicians undergoing PGT who started their specialist training during the years 2018–2021. The survey was disseminated through the Spanish regional medical councils to all active psychiatry resident physicians by mail as well as through informal communication channels. The study was authorised by the Spanish Medical Organization’s General Assembly which is the highest ethical and deontological body of physicians in Spain.

55 responses were obtained, of which 61.82% identified as females. The mean number of on-call shifts in the last 3 months was 14.05. This mean was highest in women 14,32 and in the cohort of 2020 15.46 (first year of residency). Among the resident physicians surveyed, 66.07% exceeded the 48h per week limit set by the EWTD and 7% of them did not rest after a 24-h on-call shift. Furthermore, 22% of respondents did not have a day-off after a Saturday on-call shift. The mean working hours when not resting after an on-call-shift were 7 hours. The comparison by gender and year of residency of the main variables can be seen in figures 1 and 2 respectively.

Image 2:

Psychiatry resident physicians in Spain greatly exceed the established 48 h/week EWTD limit. Likewise, non-compliance with labour regulations regarding mandatory rest after on-call duty and minimum weekly rest periods are observed. Differences can be seen by gender and year of residency. The situation described could potentially create a high-risk situation for the health and psychosocial well-being of resident physicians, hinder learning outcomes and could lead to suboptimal patient care.

Factors such as physical activity and sports participation may have a positive effect on executive functioning. However, people involved in sports are at a higher risk of experiencing a concussion, which may have a detrimental effect. Previous research has yet to investigate those combined negative and positive effects while also utilizing a comprehensive assessment of executive function. This study aims precisely to examine the effects of physical activity, athletic status and concussion history on subjective (e.g., questionnaire) and objective measures (e.g., latent variables) of three well-established components of executive function (i.e., inhibiting, shifting, and updating) in young adults.

247 Canadian university students (ages 18 - 25; 83% female) completed a remote assessment of executive function involving nine computerized tasks and a behavioural self-report, in addition to demographic questionnaires and items assessing weekly physical activity, athletic status, and concussion history. A linear regression analysis was used to assess the effects of the predictor variables (age, sex, concussion history, physical activity and athletic status) on subjective reporting of executive functioning using the Executive Function Index. Furthermore, structural equation modelling (SEM) was used to predict objective executive function using a three-factor model (shifting, updating, inhibition).

The three-factor measurement model of executive function fit the data adequately: x2 = 26.10, df = 17, p = 0.07, CFI = 0.97, TLI = 0.95, RMSEA = 0.05 [90% CI: 0.00-0.09], SRMR = 0.04. Then, the three-factor SEM of executive function also fit the data adequately: X2 = 66.38, df = 51, p = 0.07, CFI = 0.95, TLI = 0.93, RMSEA = 0.04 [90% CI: 0.00-0.06], SRMR = 0.05. Using SEM, no direct relationship was found between the factors of executive function and the predictor variables (i.e., age, physical activity, concussion history, and athletic status). Sex was significantly related to inhibition (b = 0.52, p = 0.02), such that males had greater inhibition. For the regression, physical activity (b = 0.09, p < .01), concussion history (b = 3.29, p < .05) and athletic status (b = -4.01, p < .05) were found to be significant predictors for the Executive Function Index.

Concussion history, physical activity, and athletic status were all predictive of subjective but not objective measures of executive function. Interestingly, these findings align with previous research that demonstrated performance-based executive function measures often do not align with self-report measures, which may suggest they are complementary but measure slightly different aspects of the underlying executive function construct. Mixed findings in the extant literature regarding sex differences and executive function require continued research to understand better the relationship and mechanisms behind the sex differences in inhibition. In summary, these findings offer support for the differentiation between subjective and objective measures of executive function when investigating their relationship with physical activity, sport participation, concussion history, age and sex.

Negative symptoms has been classically associated with cognition, psychosocial functioning and quality of life in patients with schizophrenia. But negative symptoms are not a unitary construct, encompassing two different factors: diminished expression, and motivation and pleasure. Few works have studied the relationship between these two different negative symptoms factors and cognition (neuro and social cognition), psychosocial functioning and quality of life, jointly, in patients with a first psychotic episode of schizophrenia.

The objective of the present work was to study, in a sample of patients with a first psychotic episode of schizophrenia, the relationship between the negative symptoms (diminished expression and motivation and pleasure) and neurocognition, social cognition, functioning and quality of life.

The study was carried out with 82 outpatients with a first psychotic episode of schizophrenia from two Spanish hospitals (“12 de Octubre” University Hospital, Madrid and “Virgen de la Luz” Hospital, Cuenca). The patients were assessed with the Clinical Assessment Interview for Negative Symptoms (CAINS) for evaluating diminished expression (EXP) and motivation and pleasure (MAP) symptoms, the MATRICS Consensus Cognitive Battery (MCCB) for evaluating neurocognition and social cognition, the Social and Occupational Functioning Assessment Scale (SOFAS), and the Quality of Life Scale (QLS).

A negative correlation was found between neurocognition and the two negative symptoms subscales: CAINS-EXP (r=-0.458, p<0.001) and CAINS-MAP (r=-0.374, p<0.001); but with social cognition only CAINS-EXP was correlated (r=-0.236, p=0.033). Also, it was found a high negative correlation between SOFAS scores and CAINS-MAP (r=-0.717, p<0.001); and a medium negative correlation with CAINS-EXP (r=-0.394, p<0.001). Finally, QLS score was high correlated with both CAINS subscales: CAINS-EXP (r=-0.681, p<0.001) and CAINS-MAP (r=-0.770, p<0.001).

This study found a relationship between negative symptoms and neurocognition, social cognition, functioning and quality of life in a sample of patients with a first psychotic episode of schizophrenia. But the two different negative symptom factors, diminished expression, and motivation and pleasure, are associated differently with psychosocial functioning, but especially with social cognition where the relationship was only found with diminished expression symptoms.

One of the great challenges still to be achieved in schizophrenia is the development of a staging model that reflects the progression of the disorder. The previous models suggested have been developed from a theoretical point of view and do not include objective variables such as biomarkers, physical comorbidities, or self-reported subjective variables (Martinez-Cao et al. Transl Psychiatry 2022; 12(1) 1-11).

Develop a multidimensional staging model for schizophrenia based on empirical data.

Naturalistic, cross-sectional study. Sample: 212 stable patients with Schizophrenia (F20). Assessments: ad hoc questionnaire (demographic and clinical information); psychopathology: PANSS, CDS, OSQ, CGI-S; functioning: PSP; cognition: MATRICS; laboratory tests: C-Reactive Protein (CRP), IL-1RA, IL-6, Platelets/Lymphocytes (PLR), Neutrophils/Lymphocytes (NLR), and Monocytes/Lymphocytes (MLR) ratios. Statistical analysis: Variables selection was performed with an ad hoc algorithm developed for this research. The referred algorithm makes use of genetic algorithms (GA) to select those variables that show the best performance for the patients classification according to their global CGI-S. The objective function of the GA maximizes the individuals correct classification of a support vector machines (SVM) model that employs as input variables those given by the GA (Díez-Díaz et al. Mathematics 2021; 9(6) 654). Models performance was assessed with the help of 3-fold cross-validation and these process was repeated 10,000 times for each one of the models assessed.

Mean age(SD): 39.5(13.54); men: 63.5%; secondary education: 59.50%. Most patients in our sample had never been married (74.10%), and more than a third received disability benefits due to schizophrenia (37.70%). The mean length of the disease was 11.98(12.02) years. The best SVM model included the following variables: 1)Clinical: number of hospitalizations, positive, negative, depressive symptoms and general psychopathology; 2)Cognition: speed of processing, visual learning and social cognition; 3)Functioning: PSP total score; 4)Biomarkers: PLR, NLR and MLR. This model was executed again 100,000 times applying again 3-fold cross-validation. In 95% of the algorithm executions more than a 53.52% of the patients were classfied in the right CGI-S category. On average the right classification was of 61.93%. About specificity and sensitivity the average values obtained were of 0.85 and 0.64 respectively.

Our staging model is a robust method that appropriately distributes patients according to the severity of the disorder. Highlights the importance of clinical, functional and cognitive factors to classify patients. Finally, the inflammatory parameters PLR, NLR and MLR have also emerged as potential biomarkers for staging schizophrenia.

Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis.

The sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene–Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use.

After controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1–3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2–2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (β = −2.3; p ⩽ 0.001; 95% CI [−3.7 to −0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0–1.8]); however, these results were no longer significant after controlling for cannabis use.

Tobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

The potential impact of the COVID-19 pandemic on suicidal behavior has generated predictions anticipating an increase in suicidal tendencies. The aim of this research is to study its influence on the incidence of hospital-treated suicide attempts throughout the year 2020 in Oviedo, Spain.

Data were collected on all patients admitted to the emergency department of Central University Hospital of Asturias in Oviedo for attempted suicide during 2020. Incidence rates were calculated for three lockdown periods. Suicide attempt trends in 2020 were compared with a non-COVID-19 year (2009) to avoid seasonal variations bias. Chi-square and Fisher’s exact tests were performed. The influence of COVID-19 incidence in Oviedo was analyzed using Spearman’s correlation coefficient.

The cumulative incidence rate of attempted suicide per 100,000 person-years was 136.33 (pre-lockdown), 115.15 (lockdown), and 90.25 (post-lockdown) in adults (over 19 years old), and 43.63 (pre-lockdown), 32.72 (lockdown), and 72.72 (post-lockdown) in adolescents (10–19 years old). No association was found with COVID-19 incidence rates (Spearman’s rho −0.222; p = 0.113). Comparing the years 2020 and 2009, statistically significant differences were observed in adolescents (Fisher’s exact test; p = 0.024), but no differences were observed in adults (chi-square test = 3.0401; p = 0.218).

Hospital-treated suicide rates attempted during the COVID-19 outbreak in Oviedo, Spain showed a similar trend compared with a non-COVID-19 year. In contrast, the number of adolescents hospital-treated for attempted suicide increased during lockdown, suggesting more vulnerability to COVID-19 restrictions after the initial lockdown period in this age group.

Bipolar disorder is related with functional impairment in euthymia. The contribution of biological functions such as sleep, sexual functioning; or the presence of obesity on this loss remain understudied.

The aim of this work was to study the influence of biological determinants in context with clinical and demographical determinants of functioning in a 3-year cohort of euthymic BD patients.

In this multicentric study 67 euthymic adult bipolar outpatients were followed during three years. Functioning was assessed with FAST, insomnia severity with Oviedo Sleep Questionnaire (OSQ) and, sexual functioning with Changes on Sexual Functioning Questionnaire (CSFQ-14) and obesity was expressed as body mass index (BMI). The basal effect of sleep, sexual functioning and obesity (Time 0) on FAST (Time 3) was analyzed with a mixed ordinal regression model including time effect, age, sex, number of manic and depressive episodes, euthymia length, and comorbidity with personality disorder. Change in functioning (Time 3 to 0) was analyzed in another mixed model also considering the difference in biological determinants (Time 3 to 0) and the presence of mood episodes during the period.

A basal worse sexual functioning, a higher severity of insomnia and a higher BMI predicted a worse functioning at three years (p=0.005, p=0.043, p=0.05 respectively). Regarding FAST difference from Time0 to 3, only having a manic episode related to an impairment on functioning (p=0.027).

Sexual functioning, quality of sleep and BMI are predictors of functioning in euthymia in BD. Manic episodes in the following contribute to impairments on functioning more than depressive episodes.

According to the World Health Organization (2016), adolescence is one of the most important transitional steps in the life of a human being, recognized by an accelerated rate of growth and changes in behavior. Adolescents from Colombia have reached this step, immersed in a context with a history of social, interpersonal and economic violence. In this sense, study of constructs such as empathy and aggressive behaviors are crucial to appease a healthy school coexistence and thus, contribute to a peace cultur

Analyze the relationship between empathy and aggressive levels from adolescents.

This study was done through a cross-sectional study of correlational scope in 240 (N= 240) students. The Prosocial Behavior Questionnaire developed by Martorell and Gonzalez (1922) and the Aggressive questionnaire, developed by Buss and Perry (1992) were applied. The first one was used to measure empathy and the latter to appraise aggressiveness.

There was evidenced of adequate levels of empathy and a great percentage of medium levels of verbal and physical aggressiveness. (Graph 1). In addition, there was a significant statistical correlation of negative magnitude between these variables (Table 1).

It was concluded that the higher the optimal levels of empathy, the lower the aggressive behavior presented by teenagers.

To examine the cross-sectional and longitudinal (2-year follow-up) associations between dietary diversity (DD) and depressive symptoms.

An energy-adjusted dietary diversity score (DDS) was assessed using a validated FFQ and was categorised into quartiles (Q). The variety in each food group was classified into four categories of diversity (C). Depressive symptoms were assessed with Beck Depression Inventory-II (Beck II) questionnaire and depression cases defined as physician-diagnosed or Beck II >= 18. Linear and logistic regression models were used.

Spanish older adults with metabolic syndrome (MetS).

A total of 6625 adults aged 55–75 years from the PREDIMED-Plus study with overweight or obesity and MetS.

Total DDS was inversely and statistically significantly associated with depression in the cross-sectional analysis conducted; OR Q4 v. Q1 = 0·76 (95 % CI (0·64, 0·90)). This was driven by high diversity compared to low diversity (C3 v. C1) of vegetables (OR = 0·75, 95 % CI (0·57, 0·93)), cereals (OR = 0·72 (95 % CI (0·56, 0·94)) and proteins (OR = 0·27, 95 % CI (0·11, 0·62)). In the longitudinal analysis, there was no significant association between the baseline DDS and changes in depressive symptoms after 2 years of follow-up, except for DD in vegetables C4 v. C1 = (β = 0·70, 95 % CI (0·05, 1·35)).

According to our results, DD is inversely associated with depressive symptoms, but eating more diverse does not seem to reduce the risk of future depression. Additional longitudinal studies (with longer follow-up) are needed to confirm these findings.

INTRODUCTION Facebook is the world’s leading social network with 2,449 million users. Around 22 million of those users are registered in Spain, and 30% of them are aged between 16 and 31. Pro-Ana and Pro-Mia pages have found a space to promote Eating Disorders (ED) as a ‘lifestyle’ using their own code.

OBJECTIVE To study the characteristics of Pro-Ana and Pro-Mia Facebook profiles in Spanish.

METHODS A non-computerized research of Facebook pages related to ED advocacy was conducted. The opened time, publications, photos, type of profiles (public/private) and link to a WhatsApp group of 58 Facebook pages were analyzed. A qualitative and descriptive analysis was carried out.

RESULTS From Facebook profiles: 62.07% contained ‘Ana’ in their profile name; 18.97% had been opened for more than 3 years; 79.31% had been shared; 48.28% mentioned Whatsapp groups; 91.38% were public profiles; 50% named other social networks; 75.86% added text to their publications; 25.86% had shared more than 20 photos on their profiles.

CONCLUSIONS On platforms like Facebook, people with ED can: advocate for their disease, set up networks, share tips/tricks and encourage other users to become part of their community. Technological developments have made it easier to access to this type of resources. Despite the platform’s policy, there are still these kind of profiles that make a case for ED.

Concerns have been raised about ecological momentary assessment (EMA) acceptability among patients with schizophrenia spectrum disorders (SSD), which is of major relevance during the e-Mental health-focused COVID-19 pandemic.

To investigate i) the levels of adherence to a passive smartphone-based EMA tool, the Evidence-Based Behavior (eB2), among SSD patients; and ii) putative predictors of this.

Sample: SSD (F20-29-ICD10) outpatients, age 18-64, without financial incentives, recruited over 17/06/2019-11/03/2020 at the Hospital Universitario Fundación Jiménez Díaz (Madrid, Spain). Those who accepted the eB2 installation -users- and those who did not -non-users- were compared in sociodemographic, clinical, premorbid adjustment, neurocognitive, psychopathological, insight and metacognitive variables by a multivariable binary logistic regression model.

Sample (N=77): n=41 males; age: 47.69±9.76 years, n=24 users (31.2%). n=14 users (70%) had the eB2 installed at follow-up (median=14.50 weeks).

X2=25.296,df=6,p<0.001. Nagelkerke-R2=44.7%. Correctly classified: 76.9%, users:54.5%, non-users:88.4%.

Acceptability of a smartphone-based EMA application among SSD patients was low. Age (young) and good premorbid adjustment predicted acceptability. e-Mental Health methods need to be tailored for patients with SSD. Otherwise, these highly vulnerable individuals may be neglected by e-health-based services in the post-COVID-19 years ahead.

It has been shown that long-acting treatments can significantly improve adherence, control symptom, and reduce the risk of relapse compared to oral drugs. However, limited real world evidence is available as to whether there are differences among the various formulations marketed.

This study aims to assess the impact on several prognosis variables of PP1M,PP3M,AOM and OAP drugs.

All adults (≥18 years) with schizophrenia who were initiated on PP1M, PP3M, AOM, or OAP treatment (chlorpromazine,levomepromazine,fluphenazine,haloperidol,ziprasidone,zuclopenthixol,olanzapine,quetiapine,asenapine,amisulpride, risperidone,aripiprazole,paliperidone) between 2017 and 2018 were identified in IQVIA’s database(1.8M of inhabitants from 4 Spanish areas). The rate of hospitalizations, emergency room visits, and treatment persistence was calculated using the Kaplan-Meier method. Survival curves were compared using the log-rank test (Sidak-adjustment),and Cox´s Hazard Ratios (HR) were used for the comparison between groups.

Data from 2275 patients were analyzed (PP1M= 387;PP3M=490;AOM=75;OAP=1323).The mean age of patients was 46.8(14.95) years, and 62.9% were male. The hospitalization rate at 12 months was significantly lower (p<0.01) for PP3M (8.3%) than for AOM (21.2%), PP1M (22.1%),and OAP (29.4%).When compared with PP3M use, the HRs were 2.17 for PP1M, 2.22 for AOM,and 2.90 for OAP. Emergency room visits rate at 12 months was also significantly lower (p<0. 01) for PP3M (23%) than for PP1M (36.9%), OAP (43.5%),and AOM (46.2%). Persistence rates were higher for PP3M (91%) than for any other treatment (p<0.01).

Our results outline that patients treated with PP3M experienced fewer relapses and decompensations compared to all other treatments analyzed, which might help improve the prognosis and quality of life of patients.

Relapse prevention is a key objetive for patients with a First Episode Psychosis (FEP) and the low adherence to antipsychotic (AP) treatment is the main reason for relapse after a FEP.

There are no clear recommendations about the early use of long-acting injectables (LAIs) in FEP. We review the impact on hospitalization rates of the early use (earlier than 1 year after the inclusion in our Early Intervention Service “Lehenak”) of LAI paliperidone in a FEP sample.

We evaluated in a naturalistic study a sample (N=384) of patients with a FEP. We carried out a mirror-design study to compare the numer of hospitalizations before and after the introduction of LAI paliperidone (1 and 3 monthly) in early users (<1 year) vs late users (>1 year).

A total of 384 FEP patients with LAI paliperidone were assessed.

There was no difference between the early and late introduction of LAI Paliperidone in the number of hospitalizations after treatament. There was a trend to present more previous hospitalizations and days in hospital in late users. This could support an earlier use of paliperidone LAI to prevent an excess of hospitalizations due to late introduction.

Eating Disorders are a frequent pathology, particularly among teenagers, a group characterized by its vulnerability and body dissatisfaction. Social networks (SN) can be a gateway to ED, mainly with Pro-Ana and Pro-Mia resources. Despite the aforementioned, SN can also be helpful for professionals, either as a tool of approach to vulnerable groups or as a way of interaction in patients already diagnosed.

To study the relationship between ED and SN, using the open access evidence available in Pubmed over the last 5 years.

A single-phase computerised search was carried out in Pubmed. The search terms were: (“Anorexia Nervosa”[Mesh] OR “Bulimia Nervosa”[Mesh] OR “Feeding and Eating Disorders”[Mesh] OR “Eating Disorders”[Tiab] OR “Eating Disorder”[Tiab] OR “Disorder, Eating”[Tiab] OR “Disorders, Eating”[Tiab] OR “Anorexia”[Tiab] OR “Bulimia”[Tiab]) AND (“blogging”[Mesh] OR “social media”[Mesh]). The filters applied were: “free Full Text” and publications for the last 5 years.

36.84% studied SN as a positive tool for ED. 47.37% revealed negative influence, only 44.44% focused on Pro-Ana and Pro-Mia. 15.79% provided both positive and negative arguments. The most studied SN were Twitter and Facebook.

Despite the known negative effect that SN can have on ED, they can also be used as a supportive recovery framework. They can be used to identify dangerous behaviours and intervene or as a prevention tool.

Eating Disorders (ED) have increased both in number of cases and diagnoses in recent years, partly due to the ease of searching on the Internet. This “community” as they call themselves has a proper language, which makes them easier to connect.

To know the search frequency of Pro-Ana and Pro-Mia terms in Spanish in the Google search engine.

A manual screening was carried out based on the word analysis of Pro-Ana and Pro-Mia blogs to obtain their search frequency in Spanish. Using the Google Trends tool, a total of 19 word combinations related to ED and their advocacy were reviewed in the time period from 01/01/2019 to 01/12/20. Some of them such as: “carrera de kilos” (kilos race), “princesa de cristal” (glass princess), “princesa de porcelana” (porcelain princess) and “dieta ABC” (ABC diet) among other terms.

From 2019 to 2020 there has been an increase in the searches related to Eating Disorders (41.63%), ABC diet (9.72%), porcelain princess (25.52%) and kilos race (38.53%). There has also been a decrease in the search for thinspo ana (30.9%), tips ana (4.15%), blog mia (13.09%) or blog ana (0.79%).

Search trends change over time as they meet the evolving needs. In several media we can find a clear increase in ED during this 2020 due to the confinement related to COVID-19. This is something that we can also relate to this increase in searches for some terms.
