Decoding semiotic minimal genome: a non-genocentric approach.

The search for the minimum information required for an organism to sustain a cellular system network has rendered both the identification of a fixed number of known genes and those genes whose function remains to be identified. The approaches used in such search generally focus their analysis on coding genomic regions, based on the genome to proteic-product perspective. Such approaches leave other fundamental processes aside, mainly those that include higher-level information management. To cope with this limitation, a non-genocentric approach based on genomic sequence analysis using language processing tools and gene ontology may prove an effective strategy for the identification of those fundamental genomic elements for life autonomy. Additionally, this approach will provide us with an integrative analysis of the information value present in all genomic elements, regardless of their coding status.

Attachment styles and associated psychosocial factors in patients at ultra-high risk for psychosis: A systematic review.

BACKGROUND: Patients with an ultra-high risk of psychosis (UHR) are more likely to transition to psychosis. Attachment style has also been associated with psychosis and other symptoms. AIMS: To review attachment styles in UHR patients and to analyze related psychosocial factors. Ours is the first systematic review of attachment in this population. METHOD: We performed a systematic review of attachment and related psychosocial factors in UHR patients following the PRISMA methodology. RESULTS: We identified five studies. The results revealed high rates of insecure attachment in this population (more than 80%). The UHR sample presented high levels of depression, anxiety, social anxiety, emotional reactivity, trauma, and poor mentalization. Premorbid social adjustment was a predictor of improvement in disorganization and negative symptoms. The rate of transition to psychosis was 10%. Attachment patterns accounted for 16.8% of the variance. This vulnerability for psychosis was also associated with poor mentalization. CONCLUSION: Early detection of patients with UHR and insecure attachment is crucial, since early intervention to address symptoms, mentalization, and attachment is feasible and may lead to an improvement in the remaining associated psychosocial related factors (secure style: better global functioning and less affective and anxious symptoms).

Association of the rs5186 polymorphism of the AGTR1 gene with decreased eGFR in patients with type 2 diabetes from Mexico City.

BACKGROUND: Early biomarkers search for Diabetic Kidney Disease (DKD) in patients with Type 2 Diabetes Mellitus (T2DM), as genetic markers to identify vulnerable carriers of the disease even before Glomerular Filtration Rate (GFR) decline or microalbuminuria development, has been relevant during the last few years. The rs5186 (A116C) polymorphism of the Angiotensin II Receptor Type I gene (AGTR1), has been associated to multiple effects of renal injury risk, commonly detected in patients with Diabetes Mellitus (DM). It has been described that rs5186 could have an effect in stability proteins that assemble Angiotensin II Receptor Type I (AT1), modifying its action, which is why it should be considered as a risk factor for Chronic Kidney Disease (CKD), characterized by a GFR progressive reduction. Even though, the association between rs5186 AGTR1 gene polymorphism and DKD in patients with T2DM has been controversial, inconclusive, and even absent. This disputable issue might be as a result of association studies in which many and varied clinical phenotypes included are contemplated as CKD inductors and enhancers. Although, the sample sizes studied in patients with T2DM are undersized and did not have a strict inclusion criteria, lacking of biochemical markers or KDOQI classification, which have hindered its examination. OBJECTIVE: The aim of our study was to establish an association between rs5186 AGTR1 gene polymorphism and GFR depletion, assessed as a risk factor to DKD development in patients with T2DM. METHODS: We analyzed 297 not related patients with T2DM, divided into 221 controls (KDOQI 1) and 76 cases (KDOQI 2). Arterial pressure, anthropometric and biochemical parameters were measured. rs5186 of AGTR1 genotyping was performed by TaqMan assay real-time PCR method. Allele and genotype frequencies, and Hardy-Weinberg equilibrium were measured. Normality test for data distribution was analyzed by Shapiro-Wilk test, variable comparison by Student's t-test for continuous variables, and Chi-squared test for categorical variables; ANOVA test was used for mean comparison of more than two groups. Effect of rs5186 to DKD was estimated by multiple heritability adjustment models for risk variables of DKD. Statistical significance was indicated by p<0.05. Data was analyzed using Statistical Package STATA v11 software. RESULTS: Dominant and Over-dominant models showed a likelihood ratio to GFR depletion of 1.89 (1.05-3.39, p=0.031) and 2.01 (1.08-3.73, p=0.023) in patients with T2DM. Risk factor increased to 2.54 (1.10-5.89) in women in Over-dominant model. CONCLUSION: In clinical practice, most of nephropathies progress at a slow pace into a total breakdown of renal function, even asymptomatic. This is the first study, reporting that rs5186 polymorphism of AGTR1 gene contribution to GFR depletion, and this could be evaluated as a predisposing factor for DKD in patients with T2DM.

Asociación del polimorfismo rs5186 del gen AGTR1 con disminución de la TFGe en pacientes con diabetes tipo 2 de la Ciudad de México / Association of the rs5186 polymorphism of the AGTR1 gene with decreased eGFR in patients with type 2 diabetes from Mexico City

Antecedentes: La búsqueda de biomarcadores tempranos de enfermedad renal diabética (ERD) en pacientes con diabetes mellitus tipo 2 (DMT2), como los marcadores genéticos para identificar pacientes vulnerables de la enfermedad, incluso antes de la presencia de una disminución de la estimación de tasa de filtrado glomerular (TFGe) o presencia de microalbuminuria ha cobrado importancia en los últimos años. El polimorfismo rs5186 (A1166C) presente en el gen receptor tipo 1 de la angiotensina II (AGTR1) ha sido asociado a distintos efectos del riesgo de daño renal que suelen estar presentes en pacientes con diabetes mellitus (DM). Se ha descrito que el rs5186 podría influir en la estabilidad de las proteínas que conforman al receptor de la angiotensina II tipo 1 (AT1) alterando su actividad, por lo que podría ser considerado como un factor de riesgo a enfermedad renal crónica (ERC) caracterizada por una disminución progresiva de la TFG. Sin embargo, la asociación del polimorfismo rs5186 del gen AGTR1 con ERD en pacientes con DMT2 ha sido controversial, no concluyente, incluso nula. Las controversias podrían ser por los estudios de asociación y estimación del riesgo del rs5186 previamente reportados incluyen distintos fenotipos clínicos considerados como inductores y potenciadores de ERC, además, los tamaños de las muestras analizadas en pacientes con DMT2 eran pequeñas y no tenían un control estricto en su inclusión, careciendo incluso de marcadores bioquímicos o estadificación KDOQI que han dificultado su análisis. Objetivo: Determinar la asociación del rs5186 del gen AGTR1 con la disminución de TFGe considerada como riesgo al desarrollo de ERD en pacientes con DMT2.(AU)

Psychopathological profile before and after bariatric surgery.

Presurgical psychopathological assessment usually focuses on detecting severe mental disorders. However, mild intensity psychopathology and eating behaviour pattern may also influence postsurgical outcomes. The aim was to identify psychopathology and eating behaviour pattern in candidates prepared for bariatric surgery compared to a normative population before and after surgery. A cohort of 32 patients seeking bariatric surgery in a university hospital between March 2016 and March 2017 were evaluated with Personality Assessment Inventory (PAI), 36-item EDE-Q and BES before and after surgery. Thirty-two patients before and 26 one year after surgery were included. The PAI presurgical psychometric profile suggested a mild mixed adjustment disorder focused on somatic complaints. After surgery, patients improved in somatic complaints (p < 0.001), and depression (p = 0.04). Related eating disorders were more common than those of the normative group and improved significantly after surgery in scores for compulsive intake (BES p < 0.001) and overall key behaviours of eating disorders and related cognitive symptoms (EDE-Q/G p < 0.001). In our cohort ready for bariatric surgery a mild psychopathological profile is still present and becomes closer to that of the normative group after surgery. Further studies are needed to evaluate the effects of mild psychopathology on outcomes after bariatric surgery.

Life Satisfaction and Dental Visits in Adults Aged ≥50 Years and Living with Diabetes Mellitus: A Comparison between Urban and Rural Mexican.

Objective: To examine the association between low life satisfaction with past-year dental visits in a rural-urban national sample of 50-year-old Mexican adults with diabetes mellitus (DM). Methods: Data are drawn from the Mexican Health and Aging Study (MHAS), a cross-sectional study conducted in 2018 involving 3,592 older adults aged 50 years and older and living in urban and rural areas in Mexico. Life satisfaction was measured using the Satisfaction with Life Scale (SWLS) and past-year dental visits dichotomized as none and ≥1 dental visits. The Poisson regression analyses were used to assess the association, adjusting for confounders. Results: 62.9% were women, mean age was 65.5 (±9.6), and 16.5% lived in a rural area, while the female subjects continue to present a higher probability of visiting a dentist (PR = 1.28 (95% CI 1.08-1.51)). In terms of age, the ≥70-year group presented 28% lower possibility of visiting a dentist (PR = 0.72 (95% CI 0.60-0.86)). The interaction showed that adults ≥50 years who reside in a rural area and have low life satisfaction were 40% less likely to have visited a dentist in the last year (PR = 0.60 (95% CI 0.37-0.98)) than adults ≥50 years who reside in an urban area and have high life satisfaction. Conclusions: The present study highlights the association between low life satisfaction and past-year dental visits in rural populations. Therefore, rurality should be considered a possible confounder in analysis of life satisfaction in the older adult population.

Differences in Patterns of Stimulant Use and Their Impact on First-Episode Psychosis Incidence: An Analysis of the EUGEI Study.

BACKGROUND: Use of illegal stimulants is associated with an increased risk of psychotic disorder. However, the impact of stimulant use on odds of first-episode psychosis (FEP) remains unclear. Here, we aimed to describe the patterns of stimulant use and examine their impact on odds of FEP. METHODS: We included patients with FEP aged 18-64 years who attended psychiatric services at 17 sites across 5 European countries and Brazil, and recruited controls representative of each local population (FEP = 1130; controls = 1497). Patterns of stimulant use were described. We computed fully adjusted logistic regression models (controlling for age, sex, ethnicity, cannabis use, and education level) to estimate their association with odds of FEP. Assuming causality, we calculated the population-attributable fractions for stimulant use associated with the odds for FEP. FINDINGS: Prevalence of lifetime and recent stimulant use in the FEP sample were 14.50% and 7.88% and in controls 10.80% and 3.8%, respectively. Recent and lifetime stimulant use was associated with increased odds of FEP compared with abstainers [fully adjusted odds ratio 1.74,95% confidence interval (CI) 1.20-2.54, P = .004 and 1.62, 95% CI 1.25-2.09, P < .001, respectively]. According to PAFs, a substantial number of FEP cases (3.35% [95% CI 1.31-4.78] for recent use and 7.61% [95% CI 3.68-10.54] for lifetime use) could have been prevented if stimulants were no longer available and the odds of FEP and PAFs for lifetime and recent stimulant use varied across countries. INTERPRETATION: Illegal stimulant use has a significant and clinically relevant influence on FEP incidence, with varying impacts across countries.

A meta-analysis of cognitive interventions for patients with recent onset psychosis: are they effective for improving functioning?

The increasing popularity of cognitive interventions for patients with psychosis calls for further exploration on how these interventions may benefit functional outcomes. We conducted a meta-analysis of randomized controlled trials (RCTs) to examine the effectiveness of cognitive interventions (i.e. Cognitive Remediation, Cognitive Training, Social Cognition, and their combination) on functioning of patients with recent onset psychosis, established as the period within the first five years from the first episode. The following databases were searched: Proquest, PUBMED/MEDLINE, PsycINFO, WOS, Scopus for research published until January 2022. In total, 12 studies were eligible. The total number of participants was 759, of which 32.2% in the intervention and 30.8% in the control group were female. We extracted data to calculate the standardized mean change from pre-test to post-test comparing the intervention with the control conditions. Overall, there was no effect of any of the cognitive intervention types on functioning. None of the examined factors (intervention type, length, and modality; control condition, follow-up time; cognitive functions; medication; symptoms) seemed to moderate these findings. Our results indicate that cognitive interventions as standalone interventions do not appear to improve functioning in patients with recent onset psychosis. Given the small number of eligible studies, further RCTs with larger and more refined samples are needed to test whether these interventions should be applied as single interventions with these patients.

Experiencias psicóticas autoinformadas: diferencias según la edad y la psicopatología asociada / Self-reported psychotic experiences: differences by age and associated psychopathology

Este trabajo pretende explorar las diferencias en sintomatología psicopatológica que puede haber en la población general adulta con o sin experiencias psicóticas (EP) en función del rango de edad. Se evaluó la presencia de EP, la sintomatología psicopatológica general y diferentes características sociodemográficas y psicosociales en 216 personas sin antecedentes psiquiátricos personales. La muestra se dividió en adultos jóvenes (18-35 años) y maduros (36-60 años). Los jóvenes mostraron una mayor expresión de EP (33,6%). Los adultos maduros con EP presentaban más sintomatología psicopatológica en las dimensiones de hostilidad-ira, somatización, depresión y ansiedad que los adultos maduros sin EP. Los adultos jóvenes con EP mostraron significativamente más síntomas en las mismas dimensiones, así como también en las dimensiones de obsesión-compulsión, ideación paranoide y psicoticismo que los participantes de esta edad sin EP. Las EP son más frecuentes en personas de 18-35 años, sin embargo, pueden estar presentes en distintos rangos de edad y podrían alertar de la presencia de niveles elevados de sintomatología afectiva y de ira-hostilidad.

This study aims to explore the differences in psychopathological symptoms that may This study aims to explore the differences in psychopathological symptoms that may exist in the general adult population with or without psychotic-like experiences (PLEs), depending on the age range. The presence of PLEs, self-reported general psychopathological symptomatology, and different sociodemographic and psychosocial characteristics were assessed in 216 participants without any record of personal psychiatric antecedents. The sample was divided into young adults (18-35 years) and mature adults (36-60 years). The young adults showed a higher expression of PLEs (33.6%). The mature adults with PLEs presented more psychopathological symptoms in the dimensions of hostility-anger, somatization, depression, and anxiety than mature adults without PLEs. Young adults with PLEs showed significantly more symptoms in the same dimensions, and in the obsession-compulsion dimensions, paranoid ideation, and psychoticism, than participants of this age without PLEs. PLEs are more frequent in people between 18-35 years old; however, PLEs can be present in different age ranges and could serve as an alert to high levels of affective and anger-hostility symptoms.

Physiological and transcriptome analyses of Kluyveromyces marxianus reveal adaptive traits in stress response.

Kluyveromyces marxianus is a non-conventional yeast with outstanding physiological characteristics and a high potential for lignocellulosic ethanol production. However, achieving high ethanol productivity requires overcoming several biotechnological challenges due to the cellular inhibition caused by the inhibitors present in the medium. In this work, K. marxianus SLP1 was adapted to increase its tolerance to a mix of inhibitory compounds using the adaptive laboratory evolution strategy to study the adaptation and stress response mechanisms used by this non-Saccharomyces yeast. The fermentative and physiological parameters demonstrated that the adapted K. marxianus P8 had a better response against the synergistic effects of multiple inhibitors because it reduced the lag phase from 12 to 4 h, increasing the biomass by 40% and improving the volumetric ethanol productivity 16-fold than the parental K. marxianus SLP1. To reveal the effect of adaptation process in P8, transcriptome analysis was carried out; the result showed that the basal gene expression in P8 changed, suggesting the biological capability of K. marxianus to activate the adaptative prediction mechanism. Similarly, we carried out physiologic and transcriptome analyses to reveal the mechanisms involved in the stress response triggered by furfural, the most potent inhibitor in K. marxianus. Stress response studies demonstrated that P8 had a better physiologic response than SLP1, since key genes related to furfural transformation (ALD4 and ALD6) and stress response (STL1) were upregulated. Our study demonstrates the rapid adaptability of K. marxianus to stressful environments, making this yeast a promising candidate to produce lignocellulosic ethanol. KEY POINTS: • K. marxianus was adapted to increase its tolerance to a mix of inhibitory compounds • The basal gene expression of K. marxianus changed after the adaptation process • Adapted K. marxianus showed a better physiological response to stress by inhibitors • Transcriptome analyses revealed key genes involved in the stress response.

COVID-19 pandemic and mental health in Spain: An analysis of their relationship using Google Trends.

INTRODUCTION: This study aims to examine the public interest that exists on Internet regarding various mental health topics and its relationship with evolution of COVID-19 pandemic in Spain. MATERIALS AND METHODS: Google Trends was used to explore relative search volume (RSV) for the following terms related with mental health (TRMH): "anxiety", "depression", "stress", "insomnia" and "suicide"; between January and December 2020. The cross-correlation function was performed to assess association between new COVID-19 cases and RSV levels for TRMH. Finally, Mann-Whitney test was used to examine differences between RSV values for TRMH before and after of state of alarm declarations on March and October 2020. RESULTS: The "anxiety" term showed the highest RSV indices. A significant correlation was found between new COVID-19 cases and RSV for "anxiety" with a time-lag of +1 week (r=0.49; p<.05). Was found an increase of SRV for "anxiety" (U=0.00; p=.01) and a decrease of SRV for "depression" (U=1.00; p=.04) between 4-week period before and after state of alarm of March 2020. Regarding the state of alarm of October 2020, a higher RSV for "anxiety" (U=0.50; p=.02) was found in the four weeks after it compared with a similar previous period. CONCLUSIONS: Anxiety is the mental health topic of greatest public interest on Internet in context of COVID-19 pandemic. Public concern about anxiety rises one week after the increase in COVID-19 cases and is greater after introduction of control measures that entail any type of mobility restriction or activity limitation. There is a greater general need for information on anxiety at specific times in the pandemic evolution.

Vaccination against SARS-CoV-2 and its relationship with public interest in mental health: a study between 2020-2022 in Spain.

The possible relationship between vaccination against SARS-CoV-2 (COVID-19) and mental health has been largely unexplored. We investigated variations in public interest in mental health issues between the different periods of the vaccination campaign against SARS-CoV-2 in Spain and before the initiation of the campaign. Using Google Trends, we explored the relative search volume (RSV) for the terms 'anxiety', 'depression', 'stress', 'insomnia', and 'suicide' between 03/01/2020 and 01/15/2022. The RSV was compared for these terms with respect to four periods: the pre-vaccination pandemic period; the period running from initiation of vaccination until 50% of the population was fully vaccinated (FV); the period running from 50% FV to 70% FV; and the period after 70% FV. Differences in the RSV indices were observed between the studied periods for 'anxiety'(F = 6.07; p = 0.001; ƞ2 = 0.16), 'stress' (F = 7.77; p < 0.001; ƞ2 = 0.19), and 'insomnia' (F = 3.80; p = 0.013; ƞ2 = 0.11). A lower RSV was found for 'anxiety', 'stress', and 'insomnia' after 70% FV compared to the two previous vaccination periods. A lower RSV was also found for 'stress' after achieving the milestone of 70% FV in relation to the period prior to initiation of the campaign. In conclusion, there is less need for information on specific mental health topics in the period after 70% FV. In Spain, reaching this vaccination milestone may have had a positive impact on anxiety, stress, and insomnia levels in the population, as reflected in fewer web searches for information on these psychopathological processes. The promotion of the COVID-19 vaccination campaign could take into account the changes observed in this preliminary study with respect to public interest in stress, anxiety, and insomnia once a large percentage of the population has been vaccinated.

Efficacy of technology-based interventions in psychosis: a systematic review and network meta-analysis.

BACKGROUND: Technology-based interventions (TBIs) are a useful approach when attempting to provide therapy to more patients with psychosis. METHODS: Randomized controlled trials of outcomes of TBIs v. face-to-face interventions in psychosis were identified in a systematic search conducted in PubMed/Ovid MEDLINE. Data were extracted independently by two researchers, and standardized mean changes were pooled using a three-level model and network meta-analysis. RESULTS: Fifty-eight studies were included. TBIs complementing treatment as usual (TAU) were generally superior to face-to-face interventions (g = 0.16, p ≤ 0.0001) and to specific outcomes, namely, neurocognition (g = 0.13, p ≤ 0.0001), functioning (g = 0.25, p = 0.006), and social cognition (g = 0.32, p ≤ 0.05). Based on the network meta-analysis, the effect of two TBIs differed significantly from zero; these were the TBIs cognitive training for the neurocognitive outcome [g = 0.16; 95% confidence interval (CI) 0.09-0.23] and cognitive behavioral therapy for quality of life (g = 1.27; 95% CI 0.46-2.08). The variables educational level, type of medication, frequency of the intervention, and contact during the intervention moderated the effectiveness of TBIs over face-to-face interventions in neurocognition and symptomatology. CONCLUSIONS: TBIs are effective for the management of neurocognition, symptomatology, functioning, social cognition, and quality of life outcomes in patients with psychosis. The results of the network meta-analysis showed the efficacy of some TBIs for neurocognition, symptomatology, and quality of life. Therefore, TBIs should be considered a complement to TAU in patients with psychosis.

Psicopatología general en profesionales sanitarios españoles durante la pandemia de Covid-19 y factores sociolaborales y psicológicos asociados / General psychopathology in Spanish health professionals during the Covid-19 pandemic and associated socio-occupational and psychological factors

El objetivo del estudio fue analizar las características sociolaborales, el estrés percibido, las estrategias de afrontamiento y la sintomatología psicopatológica de profesionales sanitarios y la relación entre ellas, durante la pandemia de Covid-19. Participaron 135 sanitarios (médicos, enfermeros y otros), quienes obtuvieron valores superiores a los datos normativos en las puntuaciones medias de las medidas de estrés percibido, ansiedad fóbica y ansiedad. El grupo de médicos mostró un nivel de ansiedad y somatización más bajo que el grupo formado por otros profesionales sanitarios. Ser profesional médico, tener un menor grado de estrés subjetivo percibido, más afrontamiento activo y menos afrontamiento pasivo eran predictores significativos de la presencia de menos síntomas psicopatológicos. La descripción del perfil del profesional sanitario español con un menor riesgo de mostrar sintomatología psicopatológica puede ser de utilidad para identificar a grupos de sanitarios con mayor vulnerabilidad psicológica. Los hallazgos sugieren factores psicológicos específicos de interés a considerar en las intervenciones destinadas al abordaje de las necesidades de salud mental de esta población en el contexto sanitario generado por la Covid-19. (AU)

The objective of this study was to analyze the socio-occupational features, perceived stress, coping strategies and self-reported psychopathological symptoms of different groups of health professionals and the relationship among these variables during the Covid-19 pandemic. One hundred and thirty-five healthcare workers participated (medical staff, nursing staff and other health professionals), who obtained higher values than the normative data in the mean scores of perceived stress, phobic anxiety, and anxiety measures. The medical staff group showed a lower level of anxiety and somatization than the other group of healthcare professionals. Being a medical professional, having a lower level of perceived subjective stress, a greater proportion of active coping and lesser passive coping were significant predictors of fewer psychopathological symptoms. The description of a health professional profile with a lower risk of showing psychopathological symptoms can help identify healthcare groups with greater psychological vulnerability. The findings suggest specific psychological factors of interest to consider in interventions aimed at addressing the mental health needs of this population in the health context generated by Covid-19.

Association Between Self-Reported Health and Education with Past-year Dental Visits among Older Mexican Adults: Results of the Mexican Health and Aging Study 2018.

PURPOSE: To explore the relationship between of self-reported health (SRH) and educational attainment with pastyear dental visits in older adults in México. MATERIALS AND METHODS: For this cross-sectional study, data were derived from the Mexican Health and Aging Study 2018 (MHAS-2018), which used a nationally-representative sample of older adults (50 years or older) in Mexico (n = 14,085). Variables taken from the MHAS questionnaire included residence (rural/urban), years of education, SRH, multimorbidity, pain severity, and past-year dental visits. A logistic regression model was used to identify the association between the variables and past-year dental visits. RESULTS: While the percentage of past-year dental visits reported was 39.8%, this number declined with age [OR=0.76, p < 0.001], with older adults living in rural areas 34% less likely to report past-year dental visits than older adults living in urban areas. Older adults with no formal education were 73% less likely (OR=0.27; p < 0.001) to report past-year dental visits than older adults ≥10 years education. Older adults with poor SRH were 32% less likely (OR=0.68; p < 0.001) to report past-year dental visits than older adults with good/very good/excellent SRH. Sex, degree of multimorbidity, and pain level ([OR=1.37; p < 0.001] [OR=1.37; p < 0.001] and [OR=1.17; p < 0.001]) were all found to be positively associated with past-year dental visits in the study population. CONCLUSION: The present study highlights the association between poor SRH, a low level of educational attainment, and less frequent past-year dental visits, as well as the finding that past-year dental visits declined with age in the older adults sampled.

Neuropsychological functioning and suicidal behaviours in patients with first-episode psychosis: A systematic review.

INTRODUCTION: Suicidal behaviour is particularly frequent in patients with psychosis. Therefore, prevention is a key objective of mental health policies. The aim of the current work is to systematically review the association between neurocognitive functioning and suicidal behaviour in patients with first-episode psychosis (FEP). MATERIAL AND METHODS: Of the 3051 studies reviewed, only 7 met the inclusion criteria. Documents in English from their earliest date of coverage until January 2022 were searched for in the following databases: PubMed, Science Direct, Web of Science, Cochrane Library, PsycINFO (ProQuest), and Springerlink. We used the PICO strategy to collect and categorize the data from each selected manuscript. RESULTS: Overall, the results showed that the risk of suicidal behaviour is higher for FEP patients in the presence of a number of factors: poorer general neuropsychological functioning (except for working memory), poorer social cognition, more depressive symptoms, longer duration of untreated psychosis, higher awareness of the illness, poorer premorbid adjustment, and more frequent cannabis use. DISCUSSION: Comprehensive general neuropsychology and assessment of social cognition, together with routine clinical record keeping, may help to identify FEP patients at a greater risk of attempting suicide.
