Summary
We utilize asset-based frameworks to examine how college-aspiring multilingual, mainly Latina/o and African American, adolescent students from immigrant backgrounds negotiate college-related pressures and constraints and employ college knowledge when mentoring emerging bilingual immigrant peers. Using interviews, post-mentoring reflections, and critical qualitative inquiry, we highlight the mentors’ agency, constraints, and lack of institutional support as they navigated college and financial-aid processes for themselves and their immigrant peers. We discuss policy implications and the need for future research on peers in supporting tailored college guidance and in empowering students from immigrant, low-income backgrounds given their institutional constraints.

OBJECTIVES/GOALS: Women and healthcare providers from underserved rural and urban communities participated in Community Engagement (CE) studios to offer perspectives for increasing research participation of women from diverse backgrounds prior to initiating recruitment for a randomized-controlled trial comparing treatments for urgency urinary incontinence. METHODS/STUDY POPULATION: CE studios are listening sessions to gather patient or community input on specific study areas of interest before implementation. Ten CE studios were held via Zoom at five study sites (Rhode Island, Washington DC, Alabama, New Mexico, and Southern California). Each site held two studios: 1) women living with urgency urinary incontinence, 2) clinicians providing care in their areas. Participants gave recommendations on ways to increase study participation of women from diverse racial and ethnic backgrounds with a focus on recruitment and retention, identification of barriers to participation, and suggested approaches to overcome those barriers. Summaries were compiled from each CE studio to identify similar and contrasting recommendations across sites. RESULTS/ANTICIPATED RESULTS: A total of 80 participants (47 community women experiencing urgency urinary incontinence, and 33 healthcare professionals) participated across all sites. Studio participants discussed anticipated barriers for participant recruitment and retention with a focus on solutions to those barriers. Based on these suggestions, we created recruitment materials using pictures, videos, and simple terminology. We created educational content to help providers with current best practices for urinary urgency incontinence. We have allowed most study visits to be conducted virtually, identified affiliated clinics in various locations to improve proximity to undeserved communities, and have earmarked additional funds to help offset travel costs including gas, public transportation, and childcare. DISCUSSION/SIGNIFICANCE: CE studios have provided pragmatic patient- and provider-centered recommendations that have been incorporated into functional strategies to improve research participation and diversity. CTSA CE core expertise can support successful CE studio planning and implementation.

This paper compares the texture of palygorskite after acid leaching with that of the product after extraction silica is removed. These effects were evaluated on the basis of nitrogen adsorption-desorption and mercury penetration porosimetry. Acid leaching at reflux temperature with 2 N HCl resulted in an increase in surface area from 138 to 399 m2/g, due to a partial (~50%) dissolution of the octahedral sheet and the creation of microporosity. This microporosity disappeared if the silica generated by the leaching was removed. The surface area also decreased from 399 to 214 m2/g, and the pore volume decreased from 0.538 to 0.507 cm3/g. The microporosity must therefore have been due to texture development in the generated silica.

Healthcare workers (HCWs) were at increased risk for mental health problems during the COVID-19 pandemic, with prior data suggesting women may be particularly vulnerable. Our global mental health study aimed to examine factors associated with gender differences in psychological distress and depressive symptoms among HCWs during COVID-19. Across 22 countries in South America, Europe, Asia and Africa, 32,410 HCWs participated in the COVID-19 HEalth caRe wOrkErS (HEROES) study between March 2020 and February 2021. They completed the General Health Questionnaire-12, the Patient Health Questionnaire-9 and questions about pandemic-relevant exposures. Consistently across countries, women reported elevated mental health problems compared to men. Women also reported increased COVID-19-relevant stressors, including insufficient personal protective equipment and less support from colleagues, while men reported increased contact with COVID-19 patients. At the country level, HCWs in countries with higher gender inequality reported less mental health problems. Higher COVID-19 mortality rates were associated with increased psychological distress merely among women. Our findings suggest that among HCWs, women may have been disproportionately exposed to COVID-19-relevant stressors at the individual and country level. This highlights the importance of considering gender in emergency response efforts to safeguard women’s well-being and ensure healthcare system preparedness during future public health crises.

The chemical and the mineralogical composition of a group of pumiceous tuffs associated with recent salic volcanic episodes from Tenerife (Canary Islands) have been studied. The investigation focused on the two main types of pyroclastic deposits of the zone: ash-flows and ash-falls. The samples can be classified chemically as trachytic and phonolitic rocks with an intermediate silica content and a high percentage of alkali cations (Na+ and K+). The mineralogical composition, determined by X-ray diffraction, scanning electron microscopy, and optical microscopy, shows the occurrence of zeolites (mainly phillipsite, with lesser chabazite and analcime), associated with the parent glass. K-feldspar (sanidine) and calcite are accessory minerals. Zeolites are significantly more abundant in the ash-flow deposits. Zeolite formation by hydrothermal weathering in closed-system conditions varies according to the nature and the origin of the pyroclastic deposits. Tenerife phillipsites differ from typical diagenetic, lacustrine, and deep-sea phillipsites, both in chemical and mineralogical features. Alkali cations exceed divalent cations in the unit-cell that, assuming a monoclinic symmetry, has the following parameters: a = 8.46–10.55 Å, b = 14.21–14.40 Å, c = 7.80–8.70 Å, and β = 105°–110°.

Background
The prevalence of medical illnesses is high among patients with psychiatric disorders. The current study aimed to investigate multi-comorbidity in patients with psychiatric disorders in comparison to the general population. Secondary aims were to investigate factors associated with metabolic syndrome and treatment appropriateness of mental disorders.
MethodsThe sample included 54,826 subjects (64.73% females; 34.15% males; 1.11% nonbinary gender) from 40 countries (COMET-G study). The analysis was based on the registration of previous history that could serve as a fair approximation for the lifetime prevalence of various medical conditions.
ResultsAbout 24.5% reported a history of somatic and 26.14% of mental disorders. Mental disorders were by far the most prevalent group of medical conditions. Comorbidity of any somatic with any mental disorder was reported by 8.21%. One-third to almost two-thirds of somatic patients were also suffering from a mental disorder depending on the severity and multicomorbidity. Bipolar and psychotic patients and to a lesser extent depressives, manifested an earlier (15–20 years) manifestation of somatic multicomorbidity, severe disability, and probably earlier death. The overwhelming majority of patients with mental disorders were not receiving treatment or were being treated in a way that was not recommended. Antipsychotics and antidepressants were not related to the development of metabolic syndrome.
ConclusionsThe finding that one-third to almost two-thirds of somatic patients also suffered from a mental disorder strongly suggests that psychiatry is the field with the most trans-specialty and interdisciplinary value and application points to the importance of teaching psychiatry and mental health in medical schools and also to the need for more technocratically oriented training of psychiatric residents.

Objective:
The accurate assessment of instrumental activities of daily living (iADL) is essential for those with known or suspected Alzheimer's disease or related disorders (ADRD). This information guides diagnosis, staging, and treatment planning, and serves as a critical patient-centered outcome. Despite its importance, many iADL measures used in ADRD research and practice have not been sufficiently updated in the last 40-50 years to reflect how technology has changed daily life. For example, digital technologies are routinely used by many older adults and those with ADRD to perform iADLs (e.g., online financial management, using smartphone reminders for medications.) The purpose of the current study was to a) asses the applicability of technology-related iADL items in a clinical sample; b) evaluate whether technology-based iADLs are more difficult for those living with ADRD than their traditional counterparts; and c) test if adding technology-based iADL items changes the sensitivity and specificity of iADL measures to ADRD.
Participants and Methods:135 clinically referred older adults (mean age 75.5 years) undergoing neuropsychological evaluation at a comprehensive multidisciplinary memory clinic were included in this study [37% with mild cognitive impairment (MCI) and 51.5% with dementia]. Collateral informants completed the Functional Activities Questionnaire (FAQ; Pfeffer, 1982) as well as 11 items created to parallel the FAQ wording that assessed technology-related iADLs such as digital financial management (i.e. online bill pay), everyday technology skills (i.e. using a smartphone; remembering a password), and other technology mediated activities (i.e. visiting internet sites; online shopping).
Results:Care partners rated tech iADLs items as applicable for the majority of items. For example, technology skill items were applicable to 90.4% of the sample and online financial management questions were applicable for 76.4% of participants. Applicability ratings were similar across patients in their 60's and 70's, and lower in those over age 80. Care partners indicated less overall impairment on technology-related iADLs (M =1.22, SD =.88) than traditional FAQ iADLs (M =1.36, SD = .86), t(129) = 3.529, p =.001). A composite of original FAQ paperwork and bill pay items (M = 1.62, SD = 1.1) was rated as more impaired than digital financial management tasks (M = 1.30, SD = 1.09), t(122) = 4.77, p <.001). In terms of diagnostic accuracy, tech iADL items (AUC= .815, 95% CI [.731, -.890]) appeared to perform comparably to slightly better than the traditional FAQ (AUC =.788, 95% CI [.705, .874]) at separating MCI and dementia, though the difference between the two was not statistically significant in this small pilot sample.
Conclusions:Technology is rapidly changing how older adults and those with ADRD perform a host of iADLs. This pilot study suggests broad applicability of tech iADL to the lives of those with ADRD and highlights how measurement of these skills may help identify trends in iADL habits that may help to mitigate the impact of ADRD on daily functions. Further, this data suggests the need to refine and improve upon existing iADL measures to validly capture the evolving technological landscape of those living with ADRD.

Objective:
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder commonly associated with relative impairments on processing speed, working memory, and/or executive functioning. Anxiety commonly co-occurs with ADHD and may also adversely affect these cognitive functions. Additionally, language status (i.e., monolingualism vs bilingualism) has been shown to affect select cognitive domains across an individual’s lifespan. Yet, few studies have examined the potential effects of the interaction between anxiety and language status on various cognitive domains among people with ADHD. Thus, the current study investigated the effects of the interaction of anxiety and language status on processing speed, working memory, and executive functioning among monolingual and bilingual individuals with ADHD.
Participants and Methods:The sample comprised of 407 consecutive adult patients diagnosed with ADHD. When asked about their language status, 67% reported to be monolingual (English). The Mean age of individuals was 27.93 (SD = 6.83), mean education of 15.8 years (SD = 2.10), 60% female, racially diverse with 49% Non-Hispanic White, 22% Non-Hispanic Black, 13% Hispanic/Latinx, 9% Asian/Pacific Islander, and 6% other race/ethnicity. Processing speed, working memory, and executive function were measured via the Wechsler Adult Intelligence Scale-Fourth Edition Processing Speed Index, Working Memory Index, and Trail Making Test B, respectively. Anxiety was measured via the Beck Anxiety Inventory (BAI). Three separate linear regression models examined the interaction between anxiety (moderator) and cognition (processing speed, working memory, and executive function) on language. Models included sex/gender and education as covariates with Processing Speed Index and Working Memory Index as the outcomes. Age, sex/gender, and education were used as covariates when Trail Making Test B was the outcome.
Results:Monolingual and bilingual patients differed in mean age (p < .05) but did not differ in level of anxiety, education, or sex/gender. Overall, anxiety was not associated with processing speed, working memory, and executive function. However, the interaction between anxiety and language status was significantly associated with processing speed (ß = -0.37, p < .05), and executive functioning (ß = 0.82, p < .05). No associations were found when anxiety was added as a moderator for the associations between language and working memory.
Conclusions:This study found that anxiety moderated the relationship between language status and select cognitive domains (i.e., processing speed and executive functioning) among individuals with ADHD. Specifically, anxiety had a greater association on processing speed and executive functioning performance for bilinguals rather than monolinguals. Future detailed studies are needed to better understand how anxiety modifies the relationship between language and cognitive performance outcomes over time amongst a linguistically diverse sample.

Objective:
Individuals with chronic pain frequently report diminished cognitive functioning. Prior cross-sectional studies have demonstrated strong associations between chronic pain and neurocognitive impairment, most notably in memory, attention, processing speed, and executive functioning. However, there is a paucity of research evaluating visual learning and memory abilities in this population. Further, while current practice standards advocate for the use of performance validity tests (PVTs) to assess the credibility of neuropsychological test performance, they have infrequently been incorporated into studies examining chronic pain samples, despite a higher observed rate of noncredible performance in the literature. This study aimed to compare visual learning and memory performance between a mixed neuropsychiatric (MNP) group and a chronic pain group in a validity-controlled sample.
Participants and Methods:The study consisted of 371 adults referred for outpatient neuropsychological evaluation. Between groups, various PVTs were administered, which included, at minimum, one freestanding and four embedded PVTs. All patients were administered the Brief Visuospatial Memory Test-Revised (BVMT-R) as part of a comprehensive neuropsychological evaluation. Only patients classified as valid performers (<1 PVT fails; n=295) were included in the analyses (Pain: n=109; MNP: n=186). The overall sample was 69% female and racially diverse (22% non-Hispanic Black, 43% non-Hispanic White, 30% Hispanic, 3% Asian/Pacific Islander, and 2% other race/ethnicities), with a mean age of 46.8 (SD=14.8) and mean education of 13.7 years (SD=2.7). Independent samples t-tests were performed to investigate the differences in visual learning and memory abilities between the chronic pain and MNP groups.
Results:Chi-square analyses revealed significant differences between the pain and MNP groups on race, with more non-Hispanic White and Hispanic patients represented in the MNP group. There were also modest group differences in age and education. For the chronic pain group, patients scored lower on both BVMT-R Total T-Score (mean difference = 9.65T, p<.001) and BVMT Delayed Recall T-Score (mean difference = 8.97T, p<.001). The effect size was robust for both for Total T-Score (d = 0.682) and Delayed Recall T-Score (d = 0.632). In contrast, the difference in BVMT Recognition Discriminability was not statistically significant.
Conclusions:This study demonstrated significant differences in performance between mixed neuropsychiatric and chronic pain patients. Preliminary evidence indicated that chronic pain patients displayed lower visual mediated encoding and retrieval performance, although their recognition is comparable. Although the nature of this study was targeted toward visual learning and retrieval, it is likely that the known impact of chronic pain on attention, working memory, and processing speed accounts for this relationship. Future studies will benefit from further elucidating these potential mechanisms and better inform clinical decision-making and neuropsychological testing performance in patients with chronic pain.

Objective:
The influence of prior knowledge on new learning is well established. However, there has been less research dedicated to teasing apart the key components of prior knowledge’s structure that contribute to memory enhancement. In the current study, we focused on event structures, which include various relations, such as associative, causal, and temporal. Given that events possess attributes relevant to numerous cognitive memory processes, we were most interested in exploring how event structures that possess causal relations enhance new memory formation. Specifically, we examined whether events that exhibit causal associative relations provide an additional boost to new learning compared to event structures with non-causal associative relations.
Participants and Methods:Forty-six undergraduate students took part in the study. Participants’ learning of the content of image pairs that exhibit everyday, real-world events were measured using a cued recall paradigm. The stimuli consisted of 60 image pairs that illustrated two events that were related causally and associatively (i.e., causal pairs); related only associatively (i.e., non-causal pairs); or not related at all (i.e., unrelated pairs). During an encoding phase, image pairs were presented one at a time, and after the presentation of each image pair, participants answered an encoding question that focused on the relationship between the two images. After the encoding phase and a short filler task, participants were shown a cue image (always the first picture from the pair) and were asked to provide a brief written description of the content of the second presented image from each pair. Also, as a manipulation check, we asked subjects to rate each image pair on causal direction and association strength after completion of the cued recall memory task.
Results:We found that, relative to unrelated pairs, events that possess associative relations (i.e., both causal and non-causal items) benefit learning of new information. In addition, causal relations provided an additional boost to new learning. Specifically, cued recall performance is best for causal pairs, followed by non-causal pairs and unrelated pairs. Moreover, causal direction ratings significantly predict overall itemlevel accuracy above and beyond general associative relations that exist in events. We also examined recall accuracy for specific content information within each event (i.e., agent, action, object) and found that causal relations uniquely contribute to recall performance of objects and actions.
Conclusions:Overall, the present study’s findings suggest that prior event knowledge structures possessing causal and non-causal associative relations support new learning, especially compared to image pairs with no relations. Of interest, causality provides an additional boost to new learning above and beyond general associative relations. By focusing on the role of causality in event structures, our findings informed our understanding of how prior knowledge supports new learning. Considering that the effect of prior knowledge on new episodic learning is especially evident in older adults, since they more readily rely on their schematic knowledge, a future direction would entail investigating how causal links influence new memory formation in older adults.

Introduction
S100B is a calcium-binding astrocyte-specific cytokine, that is considered a biomarker of neurodegeneration; which may be involved in the imbalance of the inflammatory response observed in several brain disorders, including major depression and schizophrenia. Two meta-analyses have reported higher serum levels of S100B in patients with schizophrenia respect to healthy controls.
Different studies have described circadian and seasonal variations of biological variables, such as melatonin or cortisol. It has been reported that there is not circadian rhythm of S100B blood levels in healthy subjects. However, it is not known whether there are circadian oscillations in S100B blood concentrations in patients with schizophrenia.
ObjectivesThe aim of this study is to describe S100B serum levels in patients with schizophrenia and to analyse whether they follow a circadian rhythm.
MethodsOur sample consists in 47 patients in acute phase and stabilized status. Blood samples were collected at 12:00 and 00:00 hours by venipuncture. Serum levels of Protein S100B were measured three times: at admission, discharge and three months after discharge. Protein S100B was measured by means of ELISA (Enzyme-linked immunosorbent assay) techniques.
Results12:00 24:00 P ADMISSION 132,95±199,27 85,85±121,44 0,004 DISCHARGE 73,65±71,744 75,80±123,628 0,070 CONTROL 43,49±34,60 40,14±23,08 0,47 P global P Admission Vs. Discharge P Admission Vs. Control P Discharge Vs. Control 0,97 There is a significance difference between 12:00 and 24:00 at admission for the Protein S100B.However, these difference did not occur at discharge and at three months after discharge.It can be interpreted as there is a circadian rhythm of Protein S100B when the patient has got a psychotic outbreak and disappears at discharge and when is psychopathologically stable.
ConclusionsWith respect to our results we can hypothesize that schizophrenic patients in acute relapse present circadian S100B rhythm that is not present when the patients are clinically stable.Furthermore, the decrease of serum protein S100B levels at discharge is indicative of a reduction of the cerebral inflammation, thus it can be a biomarker of cerebral inflammation and this reduction can be the effect of the treatment. Finally, its circadianity could be a guide of this process and clinical improvement.

Introduction
There are no conclusive findings about the possible protective role of religion on students’ mental health during the COVID-19 pandemic. Therefore, more research is needed.
ObjectivesThe purpose of this study was to assess the relationship between the level of emotional distress and religiosity among students from 7 different countries during the COVID-19 pandemic.
MethodsData were collected by an online cross-sectional survey that was distributed amongst Polish (N = 1196), Bengali (N = 1537), Indian (N = 483), Mexican (N = 231), Egyptian (N = 565), Philippine (N = 2062), and Pakistani (N = 506) students (N = 6642) from 12th April to 1st June 2021. The respondents were asked several questions regarding their religiosity which was measured by The Duke University Religion Index (DUREL), the emotional distress was measured by the Depression, Anxiety, and Stress Scale-21 (DASS-21).
ResultsEgypt with Islam as the dominant religion showed the greatest temple attendance (organizational religious activity: M=5.27±1.36) and spirituality (intrinsic religiosity: M=5.27±1.36), p<0.0001. On another hand, Egyptian students had the lowest emotional distress measured in all categories DASS-21 (depression: M=4.87±10.17, anxiety: M=4.78±10.13, stress: M=20.76±11.46). Two countries with the dominant Christian religion achieved the highest score for private religious activities (non-organizational religious activity; Mexico: M=3.94±0.94, Poland: M=3.63±1.20; p<0.0001) and experienced a moderate level of depressive symptoms, anxiety, and stress. Students from Mexico presented the lowest attendance to church (M=2.46±1,39) and spirituality (M=6.68± 3.41) and had the second highest level of depressive symptoms (M=19.13±13.03) and stress (M=20.27±1.98). Philippines students had the highest DASS-21 score (depression: M=22.77±12.58, anxiety: M=16.07±10.77, stress: M=4.87±10.08) and their level of religiosity reached average values in the whole group. The performed regression analysis confirmed the importance of the 3 dimensions (organizational religious activity, non-organizational religious activity, intrinsic religiosity) of religiosity for the well-being of students, except for the relationship between anxiety and private religious activities. The result was as presented for depression: R2=0.0398, F(3.664)=91.764, p<0.0001, SE of E: 12.88; anxiety: R2=0.0124, F(3.664)=27.683, p<0.0001, SE of E: 10,62; stress: R2= 0.0350, F(3.664)=80.363, p<0.0001, SE of E: 12.30.
ConclusionsThe higher commitment to organizational religious activity, non-organizational religious activity, and intrinsic religiositywas correlated with the lower level of depressive symptoms, stress, and anxiety among students during the COVID-19 pandemic, but taking into account factors related to religiosity explains the level of emotional well-being to a small extent.

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

Introduction
Network analysis has been used to explore the interplay between psychopathology and functioning in psychosis, but no study has used dedicated statistical techniques to focus on the bridge symptoms connecting these domains.
ObjectivesThe current study aims to estimate the network of depressive, negative, and positive symptoms, general psychopathology, and real-world functioning in people with first-episode schizophrenia or schizophreniform disorder, focusing on bridge nodes.
MethodsBaseline data from the OPTiMiSE trial were analysed. The sample included 446 participants (age 40.0±10.9 years, 70% males). The network was estimated with a Gaussian graphical model (GGM), using scores on individual items of the Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS), and the Personal and Social Performance (PSP) scale. Stability, strength centrality, expected influence (EI), predictability, and bridge centrality statistics were computed. The top 20% scoring nodes on bridge strength were selected as bridge nodes.
ResultsNodes from different rating scales assessing similar psychopathological and functioning constructs tended to cluster together in the estimated network (Fig. 1). The most central nodes (EI) were Delusions, Emotional Withdrawal, Depression, and Depressed Mood. Bridge nodes included Depression, Conceptual Disorganisation, Active Social Avoidance, Delusions, Stereotyped Thinking, Poor Impulse Control, Guilty Feelings, Unusual Thought Content, and Hostility. Most of the bridge nodes belonged to the general psychopathology subscale of the PANSS. Depression (G6) was the bridge node with the highest value.

ConclusionsThe current study provides novel insights for understanding the complex phenotype of psychotic disorders and the mechanisms underlying the development and maintenance of comorbidity and functional impairment after psychosis onset.

Introduction
Antidepressants (AD) are one of the most prescribed pharmacological treatments in developed countries. AD efficacy is well-proven in anxiety, depressive and other mental disorders, but their use is also common in individuals without psychiatric health conditions. Indeed, recent evidence reported an increase in AD prescription over the latest years. Concern has been raised on the overuse of AD in several countries, and societal policies and national guidelines have been developed to regulate their use in the general population.
Several factor might be used to explain this increase, including the more safety profile of new AD classes (i.e. SSRI, or vortioxetine) compared to old AD, a possible overall increase in the incidence of depressive and anxiety disorders, or their inappropriate prescription in mild conditions which could be managed without pharmacological treatment as first-step option in primary care (PC).
ObjectivesExplore AD prescription patterns in relation to mental health diagnoses and identify the most relevant factors involved in PC health systems. Understanding the variables influencing AD prescription would allow designing strategies and guidelines to make appropriate use of this pharmacological group in PC. As part of the PRESTO project (www.prestoclinic.cat), here we investigated the changes in frequency and the variables associated with AD prescription in a population-representative sample of people attending PC between 2010 –2019 in Catalonia, Spain.
MethodsWe retrieved AD prescription, sociodemographic, and health-related data using individual electronic health records from a population-representative sample (N=947.698) attending PC between 2010-2019. Prescription of AD was calculated using DHD (Defined Daily Doses per 1,000 inhabitants/day). We compared cumulative changes in DHD with cumulative changes in diagnoses with an indication for AD during the study period. We used Poisson regression to examine sociodemographic and health-related variables associated with AD prescription.
ResultsBoth AD prescription and mental health diagnoses with an indication for AD gradually increased. At the end of the study period, DHD of AD prescriptions and mental health diagnoses with an indication for AD reached cumulative increases of 404% and 49% respectively. Female sex (incidence rate ratio (IRR)= 2.83), older age (IRR = 25.43), and lower socio-economic status (IRR= 1.35) were significantly associated with increased risk of being prescribed an AD.
ConclusionsOur results from a large and representative cohort of patients confirm a steady increase of AD prescriptions that is not explained by a parallel increase in mental health diagnoses with an indication for AD. A trend on AD off-label and over-prescriptions in the PC system in Catalonia can be inferred from this dissociation.

Introduction
Intensive home treatment (IHT) for people experiencing a mental health crisis has been progressively established in many western countries as an alternative to in-ward admission. But is this a real alternative? We previously reported that patients treated in our IHT unit only differ from those voluntarily admitted to hospital in suicidal risk and severe behaviour disorders (not in other factors such as clinical severity) (Martín-Blanco et al., Rev Psiquiatr Salud Ment 2022;15:213-5). Now we are interested in disentangle if those patients who used to require inward management can be successfully treated at home.
ObjectivesTo describe subsequent treatment trajectories of the first 1000 admissions to our IHT unit and to compare clinical characteristics among the different groups of trajectories.
MethodsRetrospective cohort study. Subsequent treatment trajectories were collected from December 2016 to October 2022 and classified: absence, hospital, IHT, and mixed (hospital and IHT). Statistical significance was tested by means of ANOVA or Kruskal-Wallis test for quantitative variables (corrected for multiple comparisons) and chi-square tests for qualitative variables.
ResultsTables 1 shows the characteristics of the whole sample. Of the 1000 IHT admissions, 12.1% needed subsequent hospital admission(s), 12.7% IHT admission(s), and 9.3% mixed admission(s). There were no differences among these groups in median severity at IHT admission, but there were differences in the number of previous admissions (p=0.0001): the group with no subsequent admissions had less previous admissions than the other groups (pBonf<0.0001), and the group with subsequent IHT admissions had less than the group with mixed admissions (pBonf=0.0123). There were differences between groups regarding distribution of diagnoses (p<0.0001) (Fig. 1). When considering subsequent admissions by diagnosis, there were differences in severity at IHT admission (p=0.0068) and in number of previous hospitalizations (p<0.0001) (Fig. 2).

Introduction
We present the case of a sixty-seven-year-old woman who is examined for the first time in the emergency room because of a nine-month clinical picture that involves psychotic symptoms. The patient exhibits persecutory delusions that started after she shared some private information on social media. These symptoms also entail emotional distress and behavioral disturbances. She has never experienced hallucinations, but she does present delusional interpretations of the environment. Her clinical history reveals abnormalities of premorbid personality, including paranoid and immature features.
Objectives(1) We will be carrying out a differential diagnosis of late onset psychotic symptoms. We will as well be exploring the concept of Paraphrenia and analyzing its differential features in order to stablish the most suitable diagnosis for the case.
(2) The relationship between abnormalities in premorbid personality and psychotic symptoms will be covered, reviewing the available literature on this matter, and relating it to the patient’s symptomatology.
MethodsA review of the patient’s clinical history will be carried out, considering her biography, the testimony of her family and the complementary tests performed during the hospitalization period.
A bibliographic review of the available scientific literature will also be developed involving disorders that could explain psychotic symptoms in the elderly, as well as the term Paraphrenia, which describes specific features in a psychotic episode but is not included in the diagnostic manuals.
Results(1) The symptomatology that our patient exhibits may be considered atypical given the late stage of its onset and its specific features.
(2) The case could be explained under the category of Delusional Disorder. From a psychopathological point or view, it could also fit under de diagnosis of Paraphrenia as described by Ravindran et al.
(3) Pathological personality traits were assessed in premorbid personality which included paranoid and immature features.
ConclusionsIt could be useful to review the concept of the “paranoid spectrum” as proposed by some authors regarding some patient’s psychotic symptoms that don’t exactly fit any of the nowadays diagnostic categories. “Paraphrenia” could be understood as a distinct clinical entity for patients who show psychotic disorders but keep affective warmth and lack though deterioration and grossly disorganized behavior.
Most patients with late life paranoid psychoses have abnormal premorbid personalities, most usually of schizoid or paranoid type. There’s a decent amount of consensus in viewing the premorbid personality as having been abnormal as an early marker of impending psychosis.
Reformulating the way we approach diagnosis of psychotic symptoms of late onset could help us identify vulnerable patients on a premorbid stage and better classify and understand atypical entities.
