Adult Ascaris suum were dissected to obtain different worm components (body wall, body fluid, ovaries, uterus and oesophagus) which were used as antigens when testing 95 sera of naturally A. suum-infected Iberian pigs by enzyme-linked immunosorbent assay (ELISA) and Western blot (WB). Pigs with patent Ascaris infections had significantly lower ELISA optical density values than pigs without adult worms when using the body fluid and the body wall as antigens. A poor negative correlation was found between adult intestinal worm burden or eggs in faeces and specific antibody responses, measured by ELISA and WB using all antigens. By WB, the recognition of specific bands was variable, but three groups of bands with molecular weights of 97 kDa, 54–58 kDa and 42–44 kDa were generally recognized by sera from naturally infected pigs as well as from hyperimmunized pigs when using the five antigen extracts. The ELISA and WB techniques may be used for immunodiagnosis, using somatic adult worm antigens, to declare young pigs to be Ascaris-free but cannot be used for individual Ascaris-diagnosis in adult Iberian pigs.

OBJECTIVES/GOALS: * Patients with skin of color (SOC) are disproportionately affected by systemic lupus erythematosus (SLE) and cutaneous lupus erythematosus (CLE). In this study, we aim to address this disparity and characterize the real-world efficacy and tolerability of anifrolumab in CLE patients using validated disease activity instruments. METHODS/STUDY POPULATION: This single-center, prospective observational cohort study includes SLE patients with severe or refractory CLE who have received ≥ 1 dose of anifrolumab. Cutaneous disease activity is assessed periodically at 2, 6, 9, 12, and 18 months using the Cutaneous Lupus Disease Area and Severity Index (CLASI). Adverse events and concurrent treatments are also routinely evaluated. To date, 22 patients have been enrolled, with 6-month follow-up data available for 15. At the time of anifrolumab initiation, 95% of participants had discoid LE (DLE), 60% had mucosal DLE, and 13% had subacute CLE. Nine patients identified as SOC, two as White, and four did not report race/ethnicity. RESULTS/ANTICIPATED RESULTS: A Friedman test showed statistically significant changes over time in CLASI activity score (CLASI-A) (χ2(2) =20, p<0.0001) (Figure 1) and CLASI damage score (CLASI-D) (χ2(2) =9.5789, p=0.0083) (Figure. To estimate effect sizes, we employed linear mixed models, which demonstrated statistically significant reductions in the CLASI-A score from baseline by an average of 14 points at 2 months (p<0.001) and 18 points at 6 months (p<0.001); notably, a reduction in CLASI-A of 4 is considered clinically meaningful. At 2 months, 20% of patients experienced a 50% or more reduction in CLASI, which increased to 60% of patients at 6 months. Patients on systemic corticosteroids could taper off. Adverse events were minimal and did not lead to treatment discontinuation.

Effective treatments for refractory CLE are elusive. Our study represents the largest single-center cohort of CLE patients treated with anifrolumab and suggests that it is a promising therapeutic option for patients with SOC.

We studied the relationships between functional alpha and beta diversities of fleas and their small mammalian hosts in 4 biogeographic realms (the Afrotropics, the Nearctic, the Neotropics and the Palearctic), considering 3 components of alpha diversity (functional richness, divergence and regularity). We asked whether (a) flea alpha and beta diversities are driven by host alpha and beta diversities; (b) the variation in the off-host environment affects variation in flea alpha and beta diversities; and (c) the pattern of the relationship between flea and host alpha or beta diversities differs between geographic realms. We analysed alpha diversity using modified phylogenetic generalized least squares and beta diversity using modified phylogenetic generalized dissimilarity modelling. In all realms, flea functional richness and regularity increased with an increase in host functional richness and regularity, respectively, whereas flea functional divergence correlated positively with host functional divergence in the Nearctic only. Environmental effects on the components of flea alpha diversity were found only in the Holarctic realms. Host functional beta diversity was invariantly the best predictor of flea functional beta diversity in all realms, whereas the effects of environmental variables on flea functional beta diversity were much weaker and differed between realms. We conclude that flea functional diversity is mostly driven by host functional diversity, whereas the environmental effects on flea functional diversity vary (a) geographically and (b) between components of functional alpha diversity.

We demonstrate the importance of radio selection in probing heavily obscured galaxy populations. We combine Evolutionary Map of the Universe (EMU) Early Science data in the Galaxy and Mass Assembly (GAMA) G23 field with the GAMA data, providing optical photometry and spectral line measurements, together with Wide-field Infrared Survey Explorer (WISE) infrared (IR) photometry, providing IR luminosities and colours. We investigate the degree of obscuration in star-forming galaxies, based on the Balmer decrement (BD), and explore how this trend varies, over a redshift range of $0<z<0.345$. We demonstrate that the radio-detected population has on average higher levels of obscuration than the parent optical sample, arising through missing the lowest BD and lowest mass galaxies, which are also the lower star formation rate (SFR) and metallicity systems. We discuss possible explanations for this result, including speculation around whether it might arise from steeper stellar initial mass functions in low mass, low SFR galaxies.

Objective:
A commonly used confrontation naming task used in the United States is The Boston Naming Test (BNT). Performance differences has been found in Caucasian and ethnic minorities on the BNT. The Cordoba Naming Test (CNT) is a 30-item confrontation naming task developed in Argentina. Past research has shown acculturation levels can influence cognitive performance. Furthermore, one study evaluated geriatric gender differences on CNT performance in Spanish. Researchers reported that older male participants outperformed female participants on the CNT. To our knowledge, researchers have not evaluated ethnic differences on the CNT using a geriatric sample. The purpose of the present study was to examined CNT performance and acculturation in a Latinx and Caucasian geriatric sample. It was predicted the Caucasian group would outperform the Latinx group on the CNT. Moreover, the Caucasian group would report higher acculturation levels on the Abbreviated Multidimensional Acculturation Scale (AMAS) compared to the Latinx group.
Participants and Methods:The sample consisted of 9 Latinx and 11 Caucasian participants with a mean age of 66.80 (SD =6.10), with an average of 14.30 (SD = 2.00) years of education. All participants were neurologically and psychologically healthy and completed the CNT and the AMAS in English. Acculturation was measured via the AMAS English subscales (i.e., English Language, United States. Identity, United States, Competency). A series of ANCOVAs, controlling for years of education completed and gender, was used to evaluate CNT performance and acculturation.
Results:The ethnic groups were not well demographically matched (i.e., years of education and gender).We found that the Caucasian group outperformed the Latinx group on CNT performance p = .012, ηp 2 = .34. Furthermore, the Caucasian group reported higher acculturation levels (i.e., English Language, United States, Identity, United States, Competency) compared to the Latinx group p’s < .05, ηps2 = .42-.64.
Conclusions:To our knowledge, this is the first study to evaluate CNT performance between ethnic groups with a geriatric sample. As expected the Caucasian group outperformed the Latinx group on the CNT. Also, as expected the Caucasian group reported higher English acculturation levels compared to the Latinx group. Our findings are consistent with past studies showing ethnic differences on confrontational naming performance (i.e., The Boston Naming Test), favoring Caucasians. A possible explanation for group differences could have been linguistic factors (e.g., speaking multiple languages) in our Latinx group. Therefore, since our Latinx group reported lower levels of English Language, United States identity, and United States competency the Latinx group assimilation towards United States culture might of influence their CNT performance. Future studies with different ethnic groups (e.g., African-Americans) and a larger sample size should examine if ethnic differences continue to cross-validate in a geriatric sample.

Objective:
A 30-item confrontation naming test was developed in Argentina for Spanish speakers, The Cordoba Naming Test (CNT). The Boston Naming Test is an established confrontation naming task in the United States. Researchers have used the Boston Naming Test to identify individuals with different clinical pathologies (e.g., Alzheimer’s disease). The current literature on how Spanish speakers across various countries perform on confrontational naming tasks is limited. To our knowledge, one study investigated CNT performance across three Spanish-speaking countries (i.e., Argentina, Mexico, and Guatemala). Investigators found that the Guatemalan group underperformed on the CNT compared to the Argentine and Mexican groups. The purpose of this study was to extend the current literature and investigate CNT performance across five Spanish-speaking countries (i.e., Argentina, Mexico, Guatemala, Colombia, United States). We predicted that the Argentine group would outperform the other Spanish-speaking countries.
Participants and Methods:The present study sample consisted of 502 neurologically and psychologically healthy participants with a mean age of 29.06 (SD = 13.41) with 14.75 years of education completed (SD = 3.01). Participants were divided into five different groups based on their country of birth and current country residency (i.e., United States, Mexico, Guatemala, Argentina, & Colombia). All participants consented to voluntary participation and completed the CNT and a comprehensive background questionnaire in Spanish. The CNT consisted of 30 black and white line drawings, ranging from easy to hard in difficulty. An ANCOVA, controlling for gender, education, and age, was used to evaluate CNT performance between the five Spanish-speaking country groups. Meanwhile, a Bonferroni post-hoc test was utilized to evaluate the significant differences between Spanish-speaking groups. We used a threshold of p < .05 for statistical significance.
Results:Results revealed significant group differences between the five Spanish speaking groups on the CNT, p = .000, np2 = .48. Bonferroni post-hoc test revealed that the United States group significantly underperformed on the CNT compared to all the Spanish-speaking groups. Next, we found the Guatemalan group underperformed on the CNT compared to the Argentinian, Mexican, and Colombian groups. Additionally, we found the Argentinian group outperformed the Mexican, Guatemalan, and United States groups on the CNT. No significant differences were found between the Argentinian group and Colombian group or the Mexican group and Colombian group on the CNT.
Conclusions:As predicted, the Argentinian group outperformed all the Spanish-speaking groups on the CNT except the Colombian group. Additionally, we found that the United States group underperformed on the CNT compared to all the Spanish-speaking groups. A possible explanation is that Spanish is not the official language in the United States compared to the rest of the Spanish-speaking groups. Meanwhile, a possible reason why the Argentinian and Colombian groups demonstrated better CNT performances might have been that it was less culturally sensitive than the United States, Mexican, and Guatemalan groups. Further analysis is needed with bigger sample sizes across other Spanish-speaking countries (e.g., Costa Rica, Chile) to evaluate what variables, if any, are influencing CNT performance.

Aim
To investigate the occurrence of traumatic stress symptoms (TSS) among healthcare workers active during the COVID-19 pandemic and to obtain insight as to which pandemic-related stressful experiences are associated with onset and persistence of traumatic stress.
MethodsThis is a multicenter prospective cohort study. Spanish healthcare workers (N = 4,809) participated at an initial assessment (i.e., just after the first wave of the Spain COVID-19 pandemic) and at a 4-month follow-up assessment using web-based surveys. Logistic regression investigated associations of 19 pandemic-related stressful experiences across four domains (infection-related, work-related, health-related and financial) with TSS prevalence, incidence and persistence, including simulations of population attributable risk proportions (PARP).
ResultsThirty-day TSS prevalence at T1 was 22.1%. Four-month incidence and persistence were 11.6% and 54.2%, respectively. Auxiliary nurses had highest rates of TSS prevalence (35.1%) and incidence (16.1%). All 19 pandemic-related stressful experiences under study were associated with TSS prevalence or incidence, especially experiences from the domains of health-related (PARP range 88.4–95.6%) and work-related stressful experiences (PARP range 76.8–86.5%). Nine stressful experiences were also associated with TSS persistence, of which having patient(s) in care who died from COVID-19 had the strongest association. This association remained significant after adjusting for co-occurring depression and anxiety.
ConclusionsTSSs among Spanish healthcare workers active during the COVID-19 pandemic are common and associated with various pandemic-related stressful experiences. Future research should investigate if these stressful experiences represent truly traumatic experiences and carry risk for the development of post-traumatic stress disorder.

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

Introduction
Pathologic grooming disorders can lead to clinically significant distress and functional impairment. Various psychopharmacological and nonpharmacological treatments have been used to ameliorate the symptoms of these disorders. N-Acetylcysteine (NAC) is a newer modality in the treatment of these disorders and has shown promise in treatment of obsessive-compulsive and related disorders.
ObjectivesTo determine whether NAC is useful in the treatment of body-focused repetitive behavior disorders.
MethodsA literature review was carried out in PubMed using the descriptors: “body-focused repetitive behaviour disorders” “grooming disorders” AND “N-Acetylcysteine”.
Six results were obtained when using the time limit of 5 years. We selected two of them for their relevance to the PICO question. Subsequently, the search was repeated using the same descriptors and the time limit in the Cochrane Library, Epistemokinos and Tripdatabase, in which no additional results were found.
ResultsOverall, thirty-three articles were included in these systematic reviews that we studied, which consisted of 23 case reports, one case series, and seven randomized controlled trials. Dosing of oral NAC ranged from 450 to 3,000 mg per day, and treatment periods lasted from 1 to 8 months. Side effects were uncommon, mild, and usually gastrointestinal in nature, with severe aggression reported in one child. Two randomized controlled trials showed a significant improvement in trichotillomania and excoriation disorder in adults. The other two were performed in pediatric population, showing no statistical difference. Two randomized controlled trials and six case reports studying the effects of NAC in patients suffering from trichotillomania (one performed in adults and the other one in infants) were included. Only the one performed in adults showed improvement when adding NAC to the treatment using the Massachusetts General Hospital, Hairpulling Scale (MGH-HPS). Four case reports and two randomized controlled trials included patients with excoriation disorder showed statistical differences in all of them. Three case reports and one randomized controlled trial in patients with onicotylomania showed a difference that wasn’t consistent after two months of treatment.
ConclusionsThere are multiple case reports an several clinical trials supporting both the safety and efficacy of NAC in the treatment of body-focused repetitive behavior disorders. Based on these positive preliminary results and the absence of serious adverse effects, carrying out a therapeutical trial with NAC is a plausible option in the management of this pathology, especially in those in which other therapeutic options have not been effective. Further studies are needed to develop a treatment algorithm and elucidate the difference in the efficacy of NAC between children and adults with this disorder.

Introduction
In the last decade, the prevalence of THC use is increasing among adolescents and adults. There is also strong evidence to suggest that cannabis use is associated with psychiatric comorbidities. The strongest evidence is found between cannabis use and psychotic disorder. However, the literature shows that those who have used cannabis in the past or for a large part of their lives are at higher risk of mood disorders, anxiety, personality disorder or other drug use than those who do not use cannabis in a harmful way.
ObjectivesTo provide an overview of the association between cannabis use and the different mental pathologies presented by the patients admitted during the study period. To describe the prevalence of THC use in the study according to the mental pathology presented by the patient.
MethodsA retrospective observational descriptive study was developed for 3 months, of all patients admitted to the acute unit of the psychiatric hospital. No exclusion criteria were included.
ResultsDuring the period of study 172 patients were admitted to the hospital, classified according to the main diagnosis we have: 49 patients suffer from schizophrenia, 26 bipolar affective disorder, 20 with depressive disorder, 20 with personality disorder, 19 with substance use disorder, 18 with other unspecified disorders and 20 patients with no known previous diagnosis. The prevalence of THC use in the study sample according to diagnosis, would be schizophrenia 16%, Bipolar affective disorder 19%, Depressive disorder 5%, Personality disorder 45%, Substance use disorder 21%, Unspecified disorders 11% and patients with no known previous diagnosis 10%.
ConclusionsThe results obtained in the study in terms of THC use are in agreement with those obtained in the literature. In our study, we observed that cannabis use is associated with psychotic disorders as well as with mood, personality and substance abuse disorders. Given that the frequency of use has increased and there is a strong association with different comorbid psychiatric diagnoses, guidance on modifications in medication strategies might be necessary.

Introduction
Patients with mental disorders frequently become non-adherent during their long term prescribed treatment. This situation frequently triggers clinical worsening and hospital admission. Therefore, non-adherence may result in poorer long term clinical outcomes and has economic implications for health-care providers (Carlos De las Cuevas et al. Neuropsychopharmacol Hung 2021; 23(4):347-362).
Objectives- To describe the adherence to oral and long acting injectable treatment in the sample of patients that were admitted to the short stay hospital unit during the period of study.
- To describe the adherence to treatment amongst psychiatric diagnosis in the sample of study.
MethodsIt was a retrospective observational study with a duration of three months. Data was collected from all patients admitted to the short stay hospital unit during the period of study and there were no specific exclusion criteria. Descriptive statistics were performed. To assess the adherence to pharmachological treatment the patient report, the family report and the pharmacy dispensation according to the existent informatic prescription platform was considered. Regarding the long acting injectable treatment the formulary of administration in the clinical history was checked.
ResultsDuring the period of study 172 patients were admitted to the short stay hospital unit. Of those, 146 patients had a previous pharmacologic prescription. Data of treatment was not possible to obtain in 7 patients. In the sample of study, 83.5% were on oral and 16.5% on long acting injectable treatment. The general adherence to treatment in the sample was 61.87%. In the oral treatment group the adherence was 58.4% and in the long acting injectable treatment group was 65.2%.
Amongst the different psychiatric diagnoses the outcomes of adherence to treatment were: 60.4% in schizophrenia and related psychosis, 62.5% in bipolar disorder, 78.6% in depression, 58.3% in personality disorders and 62% in addictive disorders.
ConclusionsIn our descriptive study adherence to treatment was higher in the long acting injectable treatment group, agreeing with the existent scientific literature.
The results of adherence for schizophrenia and bipolar disorder are similar to the ones found in scientific literature but differ from the ones for depression, being higher in our sample (Judit Lazary et al. Neuropsychopharmacol Hung 2021;23(4): 347-362). Moreover, in scientific literature it is found a similar prevalence of adherence across diagnosis (for schizophrenia, bipolar disorder and depression) whereas in our sample patients with depression showed a different and higher adherence to treatment (Judit Lazary et al. Neuropsychopharmacol Hung 2021;23(4): 347-362). In our sample, patients with personality disorders had the lowest adherence to treatment.

Introduction
The intentional use of drugs before or during sexual intercourse (chemsex) is a phenomenon of special importance in the MSM (men who have sex with men) population due to its impact on mental, physical and sexual health. Sexual health issues related to chemsex practice have been described such as difficulties in achieving sober sex, erectile dysfunction or problems with sexual desire.
ObjectivesThe objective of this study was to understand the impact of chemsex on sexual health and sexual response by the participantes of a sexual health program for chemsex users in two Substance Use Disorder Clinics in Madrid.
MethodsQualitative research approach. We analyze an anonymous survey with chemsex users with open answer questions about the impact of chemsex practice on sexual response and sexual health. Data analysis was based on thematic analysis of content.
ResultsSeveral differences were identifed between chemsex and sober sex. In sober sex it can take longer to feel aroused, sexual desire is more context-dependent and more easyly controled. They connect easily with other people needs when they had sober sex. They described difficulties with consent with some sexual practices when they were on drugs. Shame and guilt was associated with chemsex. They describe more arousal, more independent of the erotic context, longer sexual intercourse and delayed ejaculation when they had sex under the influence of drugs.
ConclusionsChemsex is a phenomenon that needs a multidisciplinary approach and mental and sexual health must be taken into account including sexological perspective. Interventions that provide sexual counselling and sexual therapy for chemsex users must be developped.

Introduction
Patients with mental disorders have a decreased life expectancy, being the main reason the cardiovascular disease. An important proportion of patients present a comorbid drug consumption. Amongst drugs, alcohol is the most frequent, and it is associated with a higher cardiovascular risk. The metabolic syndrome is one of the most employed tools to assess cardiovascular risk.
Objectives- To describe the demographic characteristics of the patients with an active alcohol consumption that were admitted to the hospital during the period of study.
- To describe the prevalence of metabolic syndrome in the sample, according to the Adult Treatment Panel III (ATP-III) criteria.
MethodsRetrospective observational study of three months duration. Data was collected from all patients admitted to the hospital during the period of study, with no specific exclusion criteria. Descriptive statistics were performed.
ResultsDuring the period of study 172 patients were admitted to the hospital (56.4% women and 43.6% men). A 44.8% presented alcohol consumption (25% sporadically, 6.4% weekly and 13.4% daily). Amongst women, 1% presented daily and 1% weekly consumption. Amongst men, 21.3% presented daily and 5.3% weekly consumption.
The prevalence of metabolic syndrome in the study sample was 29.11%. In the alcohol consumption group, the prevalence was 24.7% and differed according to the pattern of consumption: 43.5% in the daily consumption group, 27.3% in the weekly and 14% in the sporadically consumption group.
ConclusionsOn the one hand, in the sample of study a higher percentage of men present an active alcohol consumption, compared to women. It is remarkable the high percentage of daily alcohol consumption amongst men in our sample.
On the other hand, the prevalence of metabolic syndrome in our sample is similar to the one found in scientific literature regarding patients with mental disorders. It is noteworthy in our sample the increased prevalence of metabolic syndrome found in patients with a daily alcohol consumption, and a decreased prevalence in those with a sporadic pattern.

Introduction
Schizophrenia (SCH) and bipolar disorder (BD) are severe mental disordes, which have high incidence (Whiteford et al. Lancet 2013; 381 1575-86) and are the main causes of diasibility in young people (WHO 2022; https://www.who.int/news-room/fact-sheets/detail/mental-disorders).
Psycological stress appears in different mental disorders, and this is directly related to oxidative stress (Moller et al. Chem Biol Interact. 1996; 102 17-36)(Pupic-Bakrac et al. 2020; Psychiatr Danub. 32 412-9). Oxidative stress causes reticulum edoplasmic stress (ER stress) and this produces high levels of misfolded proteins. Defective proteins are degraded by the proteasome, but but when the density of misfolded proteins exceeds the capacity of the proteosome, the Unfolded and Misfolded Protein Response (UPR) is triggered through three main pathways: Inositol-requiring enzyme 1α (IRE1α); transcription factor 6 alpha (ATF6α) and protein kinase RNA-Like ER kinase (PERK), trying to recover normal protein synthesis capacity (Bermejo-Millo et al. 2018; Mol Neurobiol. 55 7973-86) (González-Blanco et al. 2022; J Cachexia Sarcopenia Muscle 13 919-31).
ObjectivesCharacterizing ER stress and UPR in SCH and BD.
MethodsWe studied ER stress and UPR in peripheral blood mononuclear cells (PBMC) from 50 patients with SCH and an equal number of patients with BD compared to their corresponding controls in order to achieve our objectives.
Western Blot assay were performed following classical procedure () and the results was normalized to Ponceau as loanding control (Nie et al. 2017; BiochemByophys Resp 12 10-13) (Sander et al. 2019; Anal Biochem 575 44-53). Proteasome activity was assessed using Proteasome Activity Assay Kit (ab107921, Abcam, Cambridge, UK).
ResultsER stress was evaluated with BiP/GRP78. Our results showed significantly increased expression in SCH (p<0,01) and BD (p<0,05), being more increased in SCH. Proteasome activity was increased in SCH and BD, being only statistically significant in SQZ (p<0,05). UPR study showed IRE1a cascade significantly activated in SCH (p<0,001) and only slight increased in BD showed without statistical differences. ATF6a pathway is measured by cleavage to active protein (50-kDa). Results showed higher expression in SCH than in BD and controls (p<0,001). In addition, PERK pathway showed higher statistical levels of p-eIF2a/eiF2a ratio in SCH than in BD and control respectively (p<0,05 and p<0,01).
ConclusionsOur results showed a greater alteration in SCH than in BD at the level of protein synthesis, which implies a greater toxicity at the cellular level and, therefore, a clear risk for the survival of cells in this pathology.

Introduction
More than 700,000 people die by suicide in 2019 globally (World Health Organitation 2021). Mental health problems constitute a risk factor for suicidal behavior and death by suicide (Hoertel et al. Mol Psychiatry 2015; 20 718–726). Different mental disorders have been related to different forms of suicidal ideation and behavior (Conejero et al. Curr Psychiatry Rep 2018; 20, 33) (Quevedo et al. Compr Psychiatry 2020; 102 152194). However, little is known on comorbidity profiles among suicide attempters.
ObjectivesThe aim of our work was to identify the psychiatric comorbidity profiles of individuals who were admitted a hospital emergency department due to a suicide attempt. Moreover, it intended to know their clinical characteristics according to comorbidity profile.
MethodsA sample of 683 attempters (71.30% female; M age= 40.85, SD= 15.48) from the SURVIVE study was used. Patients were assessed within the 15 days after emergency department admission. Sociodemographic (i.e., sex, age, marital status and employment status) and clinical data were collected. The International Neuropsychiatric Interview (MINI) was used to assess DSM-V Axis 1 mental health diagnoses and the Columbia Suicide Rating Scale (C-SSRS) to assess suicidal ideation and behavior. The Acquired Capacity for Suicide-Fear of Death Scale (ACSS-FAD), the Patient Health Questionnaire (PHQ-9) to assess the frequency of depressive symptoms during the past 2 weeks, and the General Anxiety Disorder-7 (GAD-7) scale to assess symptoms of worry and anxiety were also conducted. For the identification of comorbidity profiles, latent class analysis framework was followed considering diagnosis to each individual disorder as clustering variables. On the other hand, binary logistic regression was used to study the relationship between comorbidity profile membership and clinical factors.
ResultsTwo classes were found (Class I= mild symptomatology class, mainly featured by emotional disorder endorsement; and Class II= high comorbidity class, featured by a wide amount of endorsed diagnoses) (see figure 1). Individuals from the High comorbidity class were more likely to be female (OR= 0.98, p<.05), younger in age (OR= 0.52, p< .01), with more depressive symptoms (OR=1.09, p<.001) and have greater impulsivity (OR= 1.01, p<.05).

ConclusionsWe found two profiles of people with suicidal behavior based on the presence of mental disorders. Each of the suicidal subtypes had different associated risk factors. They also had a different profile of suicidal behavior.

Introduction
The SARS-CoV-2 pandemic has produced an unprecedented clinical situation, causing a direct and indirect impact on the physical and mental health of the population. In Spain, between March 15 and June 21 of 2020, it was decreed a home confinement that caused the interruption of the daily life of millions of people. However, there are few studies that analyze the changes produced in psychiatric care in the Emergency Department (ED).
ObjectivesTo analyze the changes produced in psychiatric emergencies, subanalysing paediatric population, during the first year of the pandemic (COV1/Y-COV1) compared to the previous year (NOCOV/Y-NOCOV1). To analyze the clinical features of patients attended during the lockdown period of the pandemic (LOCK) and compare it to the period of the pandemic after the lockdown (NOLOCK).
MethodsThrough the registry of computerized medical records, patients who attended the psychiatric hospital emergency department between 03/01/2019 and 02/28/2021 were identified. We also identified all attendances from 15/03 to 21/06 in 2019 and in 2020 to obtain variables from the lockdown period.
ResultsDuring period of this study, 2694 psychiatric visits made in the ED (1744 patients - 54.3% women, and 69.5% were between 25 and 64 years-), 1537 in NOCOV and 1157 in COV1. Significant differences were found between COV1 and NOCOV in sociodemographic variables, such as employment status and number of offspring. At a clinical level, in COV1, we observed an increase in attendance due to heteroaggressive behaviors, mania, insomnia and problems due to substance use. An increase in the prescription and/or modification of treatment was observed (59.3% vs 54.3%). During COV1, in terms of discharge follow-up in the month following the ED visit, telematic assistance increased (11.4% vs. 5.3%). During the period of study, 282 ED attendances were performed, 153 in Y-NOCOV and 129 in Y-COV1. At a clinical level, during Y-COV1, a decrease in attendances related to substance use was found significant. The sub-analysis carried out for LOCK and NOLOCK yields similar data to those obtained in the COV1 vs. NOCOV1 comparison. During lockdown, the face-to-face follow-up in the month following the ED was significantly lower (39,5% vs 57,1%) regarding telematic follow-up (24,4% vs 5,8%) In this period, an increase of adolescents without previous mental health follow-up was observed (44% LOCK vs. 22% NOLOCK).
ConclusionsOur work supports the hypothesis that the COVID-19 pandemic caused a change in psychiatric care in the ED. It also shows how lockdown changed the attendance in psychiatric emergencies, and also in the later community care attendance. Changes are detected in emergency care for adolescents during the pandemic compared to the previous year. Strikingly, our study does not reflect a quantitative increase in the demand. It would be of interest to continue collecting data after the time of the present project.

Introduction
Patients affected by mental disorders are known to have a decreased life expectancy.
One of the main reasons are cardiovascular diseases. It is known that tobacco and hypertension are risk factors to develop them. WHO estimates that hypertension is diagnosed and treated in less than half of adults with hypertension, and even less in patients with severe mental illness.
ObjectivesTo describe the demographic characteristics of patients with tobacco comsumption and hypertension admitted to a short-term hospitalization unit.
MethodsA three-month retrospective observational study. Data were collected by interviewing incoming patients and performing a blood pressure measurement, with no exclusion criteria.
ResultsOf 172 patients admitted, 100 were smokers of whom 49 were men and 51 were women. Among the smokers, a total of 18 patients were diagnosed with hypertension and 79 were not diagnosed. Within the group of patients not diagnosed with hypertension, elevated blood pressure was recorded in 5 of them. A total of 67 patients were non-smokers, 23 of whom were male and 44 female. Among the non-smokers, 19 were diagnosed with hypertension and 48 were not, despite which elevated blood pressure levels were recorded in 4 of them. No data were collected from 5 patients.
ConclusionsThe prevalence of smokers in our sample was 58%. The prevalence of patients diagnosed with hypertension was 21,51% which is coherent with the existent literature. We did not find a higher percentage of hypertensive patients among the smokers admitted. There were patients who suffered from hypertension and were not diagnosed or treated previously.

Introduction
Thyroid disorders can present with psychiatric symptons similar to depression, and, at the same time, certain treatments, like litio, can cause changes in thyroid function. Given, therefore, the importance for the treatment and care of patients, the study of thyroid function is one of the parametres that should be requested in patients with psychiatric pathology.
ObjectivesTo study the frequency of thyroid disorders in patients who where admitted to a psychiatric short stay unit.
MethodsRetrospective descriptive observational study is carried out in the acute stay unit of a psychiatric hospital. As a sample, all patients admitted to the unit over a period of three months. During admission, their sociodemographic data, the treatment they receive and their diagnosis are recorded. Secondly, blood test are performed whith differents parameters, including TSH values.
ResultsIn the total sample of 172 patients, 8 of them have TSH abnormalities. 7 of them, all women, present hypothyroidism values.
A single male patient presented values of hyperthryroidism.
ConclusionsAccording to the present study, 4,6% of the patients present alterations at the TSH at admission, although except in one case, the values were not markedly altered.
The thyroid study at admission allows detecting cases of altered TSH that are amenable to treatment and monitoring.

ResultsDifferent qualitative studies have examined the motivations for engaging in chemsex. The participants identified two main raisons: pleasure and losing inhibitions. We analyed the inhibitions described by participants: difficulties with arousal, ejaculation, social interaction in sexual context, difficulties in situations that require intimacy, sexual practices that make them feel guilt/shame (for example BDSM) problems with “erotic” self-esteem: rejection of non-normative bodies or towards non- normative gender expression perceived as undesirable.
ConclusionsUnderstanding the sexual motivations for engaging in chemsex seems necessary to develop and multidisciplinary approach. Mental health proffesionals should consider sexual counselling and sexual therapy for chemsex users in their treatment.
