The macro-social and environmental conditions in which people live, such as the level of a country’s development or inequality, are associated with brain-related disorders. However, the relationship between these systemic environmental factors and the brain remains unclear. We aimed to determine the association between the level of development and inequality of a country and the brain structure of healthy adults.

We conducted a cross-sectional study pooling brain imaging (T1-based) data from 145 magnetic resonance imaging (MRI) studies in 7,962 healthy adults (4,110 women) in 29 different countries. We used a meta-regression approach to relate the brain structure to the country’s level of development and inequality.

Higher human development was consistently associated with larger hippocampi and more expanded global cortical surface area, particularly in frontal areas. Increased inequality was most consistently associated with smaller hippocampal volume and thinner cortical thickness across the brain.

Our results suggest that the macro-economic conditions of a country are reflected in its inhabitants’ brains and may explain the different incidence of brain disorders across the world. The observed variability of brain structure in health across countries should be considered when developing tools in the field of personalized or precision medicine that are intended to be used across the world.

Achieving sustainability on the ground poses a challenge in decoding globally defined goals, such as sustainable development goals, and aligning them with local perspectives and realities. This decoding necessitates the understanding of the multifaceted dimensions of the sustainability challenges in a given context, including their underlying causes. In case studies from Brazilian drylands, we illustrate how an enhanced multiscale participatory method, combined with systems thinking tools, can shed light on systemic structures that currently entrench unsustainable development trajectories. This method offers insights into co-designing potential pathways toward sustainable futures and unlocking transformative capacities of the local population.

Translating United Nations global sustainable development goals (SDGs) into actions that address local realities and aspirations is an urgent challenge. It requires new thinking and approaches that foster the discussion about the main challenges to implementing the SDGs at multiple levels. This paper presents a novel multiscale participatory approach that combines the popular Three Horizons diagram with the formalism of causal loop diagrams in systems thinking. We present results from six multi-stakeholder dialogues held across drylands in Brazil with a focus on desired futures aligned with SDGs. Focusing on identifying the root causes and systemic structures of unsustainability, participants identified lock-ins, leverage points, and interventions for how these could be changed. The core lock-ins are the discontinuity of public policies, and the historical land and power concentration reinforced by the current expansion of large-scale agricultural, mining, and energy projects. The proposed interventions are structural and – if implemented – would contribute to achieving SDGs in an integrated manner. The unique approach developed in this study can provide leverage as it bridges the inclusivity of participatory visioning with the change potential of systems thinking tools to tackle root causes and unleash societal transformations.

We are not achieving SDGs. Understanding root causes of unsustainability is critical to move toward sustainable and just futures.

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

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

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

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

Mental Health problems and substance misuse during pregnancy constitute a serious social problem due to high maternal-fetal morbidity (Cook et al, 2017; JOCG, 39(10) ,906-915) and low detection and treatment rates (Carmona et al. Adicciones. 2022;34(4):299-308)

Our study aimed to develop and test the feasibility and acceptability of a screening and treatment clinical pathway in pregnancy, based on the combination of e-Health tools with in-person interventions and, secondly, describe the prevalence of mental illness and substance use problems in this population.

1382 pregnant women undergoing her first pregnancy visit were included in a tailored clinical pathway and sent a telematic (App) autoapplied questionnaire with an extensive battery of measures (WHO (Five) Well-Being [WHO-5],Patient Health Questionnaire [PHQ-9], General Anxiety Disorder [GAD-7], Alcohol Use Disorders Identification Test [AUDIT], Drug Abuse Screening Test [DAST], Columbia Suicide Severity Rating Scale [C-SSRS] and specifically designed questions on self-harm and psychopharmacological drugs).

Patients who did not respond to the questionnaire on their own received a counseling call.

Based on the screening results, patients were classified into five groups according to severity (Figure 1) and assigned a specific action pathway (Figure 2) that included a range of intervention intensity that goes from an individual psychiatric appointment to no intervention.

Of the 1382 women included in the clinical pathway, 565(41%) completed the evaluation questionnaires. Of these, 205 (36%) were screened as positive (Grades III,IV or V. Table 1) and 3(0.5%) were classified as needing urgent care. Of the patients offered on-line groups (100), 40% (40) were enrolled in them.Table 1:

Grade distribution of those screened as positives

Concerning prevalence rates, 73 (12,9%) patients endorsed at least moderate anxiety according to GAD-7 (≥10), 65 (11,5%) endorsed at least moderate depression according to PHQ-9 (≥ 10), 17 were positive on DAST (3%) and 63 (11%) patients scored above the threshold in AUDIT-C(≥ 3) for alcohol use.

High prevalence rates suggest that effective detection and treatment mechanisms should be integrated into usual care. The use of standardized clinical pathways can help with this aim, allowing better clinical management and referral to treatment, but still face challengues to increase retention. The use of e-health tools offers the opportunity to improve accessibility and therapeutic outcomes through online interventions.

Suicide attempts (SA) leading to highly lethal consequences have been associated with heightened suicide planning (Barker et al., 2022), along with deficits in social cognition (Levi-Belz et al., 2022). Hypomentalizing, characterized by excessive uncertainty regarding mental states, may contribute to heightened social withdrawal and an increased risk of SA (Nestor & Sutherland, 2022). Although certain studies have identified a connection between hypomentalizing profiles and self-harm (Badoud et al., 2015), research into the lethality of SA remains limited.

This study aimed to explore the association between hypomentalizing and SA lethality.

Our study encompassed a cohort of 1,371 patients who committed a SA. We conducted assessments of mentalizing using the RFQ-8 instrument, and evaluations of suicidal ideation and behavior employing the CSRSS questionnaire. Demographic and clinical characteristics were compared using the T-student and Chi-square tests. To investigate the relationship between hypomentalizing and the SA lethality, we employed logistic regression models.

Descriptive date are presented in Table 1. Our results show that hypomentalizing do not predict a higher SA lethality. Additionally, hypomentalizing increased the risk of SA planning (p≤0.001, B=-0.182), and SA planning predicted a higher SA lethality (see Table 2).Table 1.

Means Comparison for low and high lethality (N=1371)

While the association between hypomentalizing and high SA lethality was not significant, a discernible trend toward such relationship can be noted. Further studies examining the moderating effects of planning in the association between hypomentalizing and SA lethality are required.

Burnout was reclassified in 2019 as an occupational phenomenon in ICD-11. The new condition includes the classic tridimensional definition with symptoms in areas of fatigue/energy depletion, mental distance/cinism and sense of ineffectiveness/lack of accomplishment.

To evaluate the knowledge and perceptions of psychiatrists regarding new ICD-11 burnout definition.

To analyse the frequency of burnout symptoms in the psychiatric consultations and among the psychiatrists as healthcare professionals.

An online survey (designed with Microsoft® Forms) was sent in June 2023 to psychiatrists from three regions of Spain, contacted form local scientific societies. Psychiatrists, currently working, had to consent and answer a brief survey (average time: 2 min 32 sec) of 9 questions regarding the definition of burnout, their experience in clinical practice, their own symptoms and symptoms observed in colleagues.

164 psychiatrists answered, 114 females (69.5%), mean age: 43.61 ± 11.28 years. 48.2% assured they had never used the term Burnout or the ICD codes Z73.0/QD85, whereas a 9.1% used them frequently in clinical practice. 58.5% considered burnout just a condition related to work and a 38.4% either a syndrome or a disorder.

Most psychiatrists referred that their patients exhibited symptoms of the three dimensions. Fatigue was the most common, attended frequently by 79.5% of the surveyed, followed by ineffectiveness (73.1%) and cinism (65.3%).

When reporting their own symptoms, only 16.5% psychiatrists referred not suffering any symptom. The most frequently involved was fatigue (66.5%), then ineffectiveness (56.1%) and cinism (41.5%). 28,7% reported concomitant symptoms of the three dimensions.

70.7% recognized fatigue symptoms in their colleagues, 61% ineffectiveness, 72.6% cinism and 45,5% recognized symptoms from the three dimensions. Only a 7.3% did not identify any of them.

A younger age was related to higher probability of suffering cinism (T:2.546; p=0.012) and ineffectiveness (T:2.900; p=0.004) and to a higher probability of recognizing cinism (T=3,293; p=0,001) an ineffectiveness in others (T=2.355; p=0.020)

Females showed a higher frequency of ineffectiveness symptoms (61.4% vs 44%; χ2:4.274; p=0,029).

Psychiatrists’ concept of burnout is diverse but the main construct is convergent with ICD definition, not a medical illness but a condition related to work.

The three classic dimensions of burnout are common in clinical conditions and also in the laboral environment of psychiatrists themselves. Psychiatrists tend to recognized more easily burnout in other colleagues, particularly cinism symptoms. Cinism and ineffectiveness appear to be related to younger age that can be associated to an imbalance between work demands and individual resources.

These results highlight the challenge of preventing, detecting and addressing burnout syndrome in psychiatric services.

Exercise and other lifestyles are key treatment strategies to improve diabetes outcome, prevent cardiovascular risk and may also result in further results in quality if life and emotional symptoms.

To evaluate the effectiveness of an exercise intervention program for people with diabetes or cardiovascular risk.

To evaluate the influence of previous metal health and quality of life status in the results.

61 people with a type 2 diabetes or cardiovascular risk factors were recruited from health primary health centers in Ponferrada (EL Bierzo), including patients from the mental health association. After informed consent they were included in a 20 week, twice a week supervised walking training program to improve exercise and other lifestyles. A poster used for advertisement of the adtivity (“the way/walk to change diabetes”) is displayed in image 1). Baseline and after 20 weeks BMI and Waist perimeter were assessed, quality of life was evaluated with EQ-5D-5L and WHO-5 scales and the weekly steps walked were recorded previously and after the intervention with the subject usual mobile device.

Differences in the variables were compared with Paired Ts and repeated ANCOVAs measures adjusted by gender, age and initial steps.

46 subjects (75.4%) completed more than 90% of the sessions and 3 more 70-90%. The 19.7% that did not complete had worse scores in SF-12 Role Physical (t 2.261, p=0.041) and Role Emotional (t:2.048, p=0.045) and Mental Component Summary (t:2,313; p=0,036) and WHO5 Total Score (t:2.101; p=0,040) at Baseline. Main reasons for dropout (Image 2) were health related problems (50%) and adherence to exercise and motivation problems (31.25%).

Those who completed the training improve number of weekly steps (baseline: 42022,92 +- 18836,35, final: 66448.06 +-28914,58; t:5.038; p<0.001), BMI (29.45 +-4.66 to 28.25 +-4.09 kg/m2; t:5.629; p<0.001), waist (from 107,34 + 9.98 to 102,88 +9,79 cm; t:6,840; p<0.001) and the EoQ-5D-EL VAS (form 72.88 to 82.42; t:6.122; p<0.001, image 3). The increase in the steps correlated directly with the improvement in the EoQ VAS (r:0.308; p=0.033).

Exercise and lifestyle supervised intervention programs appear to be useful to improve physical health, wellbeing, emotional symptoms and quality of life in people with diabetes and cardiovascular risk.

Factors associated to higher dropout rates were previous limited quality of life scores and mental health worse status. These could be related with limited motivation and adherence to the program and may be of interest to develop specific strategies for these high-risk groups.

Studies focused on the long-term effect of the program are warranted.

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. Group therapy has been included in several programs for chemsex users.

To describe and to compare the different group therapy treatments for problematic chemsex users in NGOs community treatment settings in Spain.

We conducted several interviews with key informants from 5 NGO in Spain. A qualitative analysis of the different group therapy treatments for problematic chemsex was performed.

Different models of groups were described including: psychoeducational, support, interpersonal process, harm reduction and mindfulness-based cognitive groups. Most of the group interventions developed were support and psychoeducational based. There were fewer interpersonal group and relapse prevention group therapy. The different models of group intervention were considered useful and necessary for deliver information in a culturally sensitive context and for reducing drug use, social isolation and loneliness.

Chemsex is a phenomenon that needs a multidisciplinary approach, including individual and group therapy. Group therapy for problematic chemsex has several advantages over individual model treatments, including the reduction of sense of isolation, loneliness, information and feedback from peers. More research is needed to analyze the implementation and efficacy of group therapy for chemsex users in different contexts.

The present study aims to determine the prevalence estimates of MBI and specific MBI domains in a large sample of the general population, by degree of cognitive impairment (CI).

A representative community sample of individuals aged 55+ (n=4803) (ZARADEMP Study) was studied. MBI, and specific MBI domains, were assessed according to ISTAART-AA MBI criteria, using the Geriatric Mental State (GMS). In accordance with these criteria, clinically significant anxiety, depression, and dementia were excluded. For the standardized degree of CI Perneczky et al. ́s criteria were applied: normal (MMSE 30), questionable (MMSE 26-29), mild CI (MMSE 21-25), moderate-severe CI (MMSE <21).

The prevalence of MBI, and specifically the domain Decrease Motivation (DM), increased progressively and significantly by degree of CI, the differences being significant between all cognitive groups. After control by age and education, DM was 2- and 4.5-times more frequent in subjects with mild CI (10.6%) and moderate-severe CI (18.3%), respectively, than in cognitive normal (5.8%). Affective Dysregulation (AD) was 1.7-times more frequent in mild CI (26.4%) (vs 20.4% in normal). Impulsive Dyscontrol (ID) was 2- and 7.9-times more frequent in mild CI (8%) and moderate-severe CI (23.5%) than in cognitive normal (4.7%). And Abnormal Perception and Thoughts (APT) was 6-times more frequent in moderate-severe CI (10%) (vs 1.4% in cognitive normal).

Our results confirm an increase of MBI prevalence across the spectrum of CI. However, each specific domain of MBI shows a different pattern of association with CI. Our results support the relevance of studying MBI domains independently.

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.

The 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.

About 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.

The 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.

The coronavirus disease 2019 (COVID-19) has serious physiological and psychological consequences. The long-term (>12 weeks post-infection) impact of COVID-19 on mental health, specifically in older adults, is unclear. We longitudinally assessed the association of COVID-19 with depression symptomatology in community-dwelling older adults with metabolic syndrome within the framework of the PREDIMED-Plus cohort.

Participants (n = 5486) aged 55–75 years were included in this longitudinal cohort. COVID-19 status (positive/negative) determined by tests (e.g. polymerase chain reaction severe acute respiratory syndrome coronavirus 2, IgG) was confirmed via event adjudication (410 cases). Pre- and post-COVID-19 depressive symptomatology was ascertained from annual assessments conducted using a validated 21-item Spanish Beck Depression Inventory-II (BDI-II). Multivariable linear and logistic regression models assessed the association between COVID-19 and depression symptomatology.

COVID-19 in older adults was associated with higher post-COVID-19 BDI-II scores measured at a median (interquartile range) of 29 (15–40) weeks post-infection [fully adjusted β = 0.65 points, 95% confidence interval (CI) 0.15–1.15; p = 0.011]. This association was particularly prominent in women (β = 1.38 points, 95% CI 0.44–2.33, p = 0.004). COVID-19 was associated with 62% increased odds of elevated depression risk (BDI-II ≥ 14) post-COVID-19 when adjusted for confounders (odds ratio; 95% CI 1.13–2.30, p = 0.008).

COVID-19 was associated with long-term depression risk in older adults with overweight/obesity and metabolic syndrome, particularly in women. Thus, long-term evaluations of the impact of COVID-19 on mental health and preventive public health initiatives are warranted in older adults.

Electroconvulsive therapy (ECT) is a procedure performed under general anaesthesia involving triggering an intentional brief seizure through small electrical currents through the brain. The anaesthetic depth should be adequate prior to shock and measured with BIS, a processed electroencephalogram (EEG) monitor. Adjusting the hypnotic dose allows to decrease the ictal threshold and thus improve the response to treatment and decrease side effects.

Our goal is detecting elements such as spontaneous epileptiform activity after ECT without tonic-clonic activity with the spectral density matrix (SDM).

Our patient: an 87-year-old woman, diagnosed with F20.2 catatonic schizophrenia and under antipsychotic treatment since her youth. She has required multiple hospital admissions due to psychopathological decompensations until starting monthly maintenance ECT sessions in 2014. Since then she no new hospital admissions have been required.

Images 1D and 1E shows the SDM, a spectrogram of the EEG. The X axis show time (minutes), the Y axis shows the frequency (Hz) and the Z axis shows the energy or intensity of that electrical activity in the frequency bands replaced by colors: warm colors (red) reflecting high intensity electroencephalographic activity and cool colors (yellow, blue and green), low activity. Images 2 and 3’s EDM shows spontaneous epileptiform activity after electroconvulsive therapy without tonic-clonic activity. We observed an initial EDM of an awake patient, with warm colours in practically all frequency bands, including the beta band (13-30 Hz), characteristic of waking states. Around 9:50 anaesthetic induction occurs, activity increases in slow frequencies (red colours in alpha, theta and delta), plus an increase of cold colours in beta, reflecting the disappearance of brain activity in that frequency. The asterisk reflects the EEG response to the electrical discharge, followed by a postcritical state with brain activity exclusively in slow waves and high amplitude (delta and some theta) and absence of activity in other frequencies (blue colour in the beta and alpha bands) around 9:57. At about 10:00 there is an abrupt appearance of high intensity brain activity (warm colours) in beta and alpha and delta, mainly, reflecting spontaneous epileptiform activity after treatment and clinically reflected as a patient absent and disconnected from the environment, but without tonic-clonic activity. New postcritical state in which blue colour predominates, reflecting little brain activity, and warmer colours reappear in all frequency bands, including beta, reflecting the progressive recovery of wakefulness.

Psychiatric pathology can be reflected in the SDM, which allows to observe changes in the EEG, correcting the electrical stimulus of the shock and the dose of anesthetic appropriate to the patient to trigger an intentional brief seizure under general anesthesia.

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).

Characterizing ER stress and UPR in SCH and BD.

We 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).

ER 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).

Our 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.

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).

To 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).

Through 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.

During 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).

Our 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.

To describe IMP-type carbapenemase-producing Pseudomonas aeruginosa outbreaks at Galdakao University Hospital between March 2021 to December 2021.

Outbreak report.

Galdakao University Hospital is a tertiary-care hospital in the Basque Country (northern Spain).

All patients with a positive IMP-type carbapenemase producing Pseudomonas aeruginosa (IMP-PA) culture were included in this study, both colonization and infection cases.

An outbreak investigation was conducted, in which molecular epidemiology analysis [pulsed-field gel electrophoresis and whole-genome sequencing (WGS)] and environmental screenings were performed.

Between March and December 2021, 21 cases of IMP-PA were detected in Galdakao University Hospital: 18 infection cases and 3 colonization cases. In total, 4 different pulsotypes were detected belonging to 4 clones according to WGS: ST175 (n = 14), ST633 (n = 3), ST179 (n = 3), and ST348 (n = 1). IMP-13 was detected in most isolates belonging to the ST175 clone and in all ST179 and ST348 clones, whereas IMP-29 was detected in isolates belonging to the ST633 clone. Clinical isolates belonging to the ST175 clone were isolated mainly from patients admitted to the respiratory ward, and isolates belonging to the ST633 clone from patients admitted to the ICU. Two environmental isolates belonging to the ST175 clone were detected in the respiratory ward.

Molecular and genomic epidemiology revealed that there had been 2 independent IMP-PA outbreaks, one of long duration in the respiratory ward and the other more limited in the ICU.
