The identification of predictors of treatment response is crucial for improving treatment outcome for children with anxiety disorders. Machine learning methods provide opportunities to identify combinations of factors that contribute to risk prediction models.

A machine learning approach was applied to predict anxiety disorder remission in a large sample of 2114 anxious youth (5–18 years). Potential predictors included demographic, clinical, parental, and treatment variables with data obtained pre-treatment, post-treatment, and at least one follow-up.

All machine learning models performed similarly for remission outcomes, with AUC between 0.67 and 0.69. There was significant alignment between the factors that contributed to the models predicting two target outcomes: remission of all anxiety disorders and the primary anxiety disorder. Children who were older, had multiple anxiety disorders, comorbid depression, comorbid externalising disorders, received group treatment and therapy delivered by a more experienced therapist, and who had a parent with higher anxiety and depression symptoms, were more likely than other children to still meet criteria for anxiety disorders at the completion of therapy. In both models, the absence of a social anxiety disorder and being treated by a therapist with less experience contributed to the model predicting a higher likelihood of remission.

These findings underscore the utility of prediction models that may indicate which children are more likely to remit or are more at risk of non-remission following CBT for childhood anxiety.

Poor oral feeding is a known contributor to growth challenges in neonates with complex CHD who require early surgery. Almost 60% of these infants do not achieve full oral feeding by hospital discharge. This study’s objective was to identify predictors of the inability to achieve full oral feeding by discharge in neonates with complex CHD following surgical intervention with cardiopulmonary bypass.

A retrospective analysis of a prospective study of 192 full-term neonates with complex CHD was performed. A stepwise selection logistic regression model was developed to predict oral feeding status at hospital discharge. Univariate subgroup analysis was performed with groups determined based on a CHD classification system.

58% of neonates (112/192) failed to achieve full oral feeding by hospital discharge. A logistic regression model identified duration of deep hypothermic circulatory arrest and reintubation as predictors of the inability to achieve full oral feeding. Among neonates who achieved full oral feeding by discharge (42%), only 7.5% did so after postoperative day 10. Brain maturation, brain injury, and preoperative oral feeding were not predictors of full postoperative oral feeding.

Many infants with CHD fail to achieve full oral feeding by time of hospital discharge. Longer duration of deep hypothermic circulatory arrest and increased number of intubations were predictive of poor feeding after surgery. Prolonging hospitalisation solely to achieve full oral feeding after postoperative day ten is of limited utility; earlier discharge should be promoted to avoid negative impacts on neonatal neurodevelopment as unintended consequences of lengthy hospitalisations.

Surgical-site infections (SSIs) can be catastrophic. Bundles of evidence-based practices can reduce SSIs but can be difficult to implement and sustain.

We sought to understand the implementation of SSI prevention bundles in 6 US hospitals.

Qualitative study.

We conducted in-depth semistructured interviews with personnel involved in bundle implementation and conducted a thematic analysis of the transcripts.

The study was conducted in 6 US hospitals: 2 academic tertiary-care hospitals, 3 academic-affiliated community hospitals, 1 unaffiliated community hospital.

In total, 30 hospital personnel participated. Participants included surgeons, laboratory directors, clinical personnel, and infection preventionists.

Bundle complexity impeded implementation. Other barriers varied across services, even within the same hospital. Multiple strategies were needed, and successful strategies in one service did not always apply in other areas. However, early and sustained interprofessional collaboration facilitated implementation.

The evidence-based SSI bundle is complicated and can be difficult to implement. One implementation process probably will not work for all settings. Multiple strategies were needed to overcome contextual and implementation barriers that varied by setting and implementation climate. Appropriate adaptations for specific settings and populations may improve bundle adoption, fidelity, acceptability, and sustainability.

Psychiatric home hospitalisation is a service aiming to support people with mental illnesses in their acute stage at their own home. This care model has been recently implemented in our territory with the main objective of avoiding hospital admissions.

Our goal is to describe a cohort of patients followed up over 2-years in the context of a pilot mental health program within a community-based model (Mutua Terrassa University Hospital).

We conducted a prospective longitudinal study including 125 patients attended from 01/11/2020 to 09/11/2022 in our reference area of 250,000 inhabitants. The team was formed by 1 psychiatrist and 1 mental health nurse. DSM-5 diagnoses, socio-demographic variables, mean stay and care trajectories were collected.

One-hundred twenty-five patients were attended (women: 70). Mean age at consultation: 38.3 years-old. Mean stay: 24 days. The most frequent diagnoses: non-affective psychotic disorders (58%), affective disorders (30%), followed by anxiety and personality disorders. Referrals from Community Mental Health Outpatient Services (CMHS) (72%), Acute Inpatient Unit (25%), and Psychiatric Emergency Service (3%). Referrals after discharge: CMHS (83%), Adult Acute Inpatient Unit (13%), others (4%). Individualized mental health plans were carried out in all cases, in coordination with community mental health services. Follow-up adherence after discharge was about 95%. Patients with first-episode of psychosis showed the highest degree of satisfaction (N=46).

Patients with emerging psychosis were the profile of users who showed the highest benefit of our service. Women showed higher adherence, and loss to follow-up was lower than we expected.

Our study aimed to (1) identify trajectories on different mental health components during a two-year follow-up of the COVID-19 pandemic and contextualise them according to pandemic periods; (2) investigate the associations between mental health trajectories and several exposures, and determine whether there were differences among the different mental health outcomes regarding these associations.

We included 5535 healthy individuals, aged 40–65 years old, from the Barcelona Brain Health Initiative (BBHI). Growth mixture models (GMM) were fitted to classify individuals into different trajectories for three mental health-related outcomes (psychological distress, personal growth and loneliness). Moreover, we fitted a multinomial regression model for each outcome considering class membership as the independent variable to assess the association with the predictors.

For the outcomes studied we identified three latent trajectories, differentiating two major trends, a large proportion of participants was classified into ‘resilient’ trajectories, and a smaller proportion into ‘chronic-worsening’ trajectories. For the former, we observed a lower susceptibility to the changes, whereas, for the latter, we noticed greater heterogeneity and susceptibility to different periods of the pandemic. From the multinomial regression models, we found global and cognitive health, and coping strategies as common protective factors among the studied mental health components. Nevertheless, some differences were found regarding the risk factors. Living alone was only significant for those classified into ‘chronic’ trajectories of loneliness, but not for the other outcomes. Similarly, secondary or higher education was only a risk factor for the ‘worsening’ trajectory of personal growth. Finally, smoking and sleeping problems were risk factors which were associated with the ‘chronic’ trajectory of psychological distress.

Our results support heterogeneity in reactions to the pandemic and the need to study different mental health-related components over a longer follow-up period, as each one evolves differently depending on the pandemic period. In addition, the understanding of modifiable protective and risk factors associated with these trajectories would allow the characterisation of these segments of the population to create targeted interventions.

While adult outcome in autism spectrum disorder (ASD) is generally measured using socially valued roles, it could also be understood in terms of aspects related to health status – an approach that could inform on potential gender differences.

We investigated gender differences in two aspects of outcome related to health-status, i.e. general functioning and self-perceived health status, and co-occurring health conditions in a large multi-center sample of autistic adults. Three hundred and eighty-three participants were consecutively recruited from the FondaMental Advanced Centers of Expertise for ASD cohort (a French network of seven expert centers) between 2013 and 2020. Evaluation included a medical interview, standardized scales for autism diagnosis, clinical and functional outcomes, self-perceived health status and verbal ability. Psychosocial function was measured using the Global Assessment of Functioning scale.

While autistic women in this study were more likely than men to have socially valued roles, female gender was associated with poorer physical and mental health (e.g. a 7-fold risk for having three or more co-occurring physical health conditions) and a poorer self-perceived health status. Psychosocial function was negatively associated with depression and impairment in social communication. Half of the sample had multiple co-occurring health conditions but more than 70% reported that their visit at the Expert Center was their first contact with mental health services.

To improve objective and subjective aspects of health outcome, gender differences and a wide range of co-occurring health conditions should be taken into account when designing healthcare provision for autistic adults.

Adolescence: a state of mental fragility, where psychiatric disorders may debut, where have been reported several cases of toxidermy, encephalopathy and neuropsychiatric disorder related to ivermectin treatment (excluding organicity, substance abuse or medication) (1). It has effect on the dopaminergic system with an alteration on glycoprotein P leading to high levels of ivermectin causing neurotoxicity (2). In this poster, we discuss the case of a 14 y/o´s psychosis to ivermectin

Presentation of a clinical report

14 years old woman. Background: father with schizophrenia. Comorbility: None. Initially, presented to ER with 2 week of treatment to ivermectin 6mg for pediculosis; presenting first psychotic episode. She presented first clinical outbreak of psychosis characterized by mystical-religious, erotomaniac, harm and reference delusions, auditory and visual hallucinations adding isolation, abulia, apathy, dialogued soliloquies, and spontaneous crying. No prior psychiatric treatment.

In hospitalization: elevated indirect and direct bilirubins and hiponatremia; neuroimaging studies are reported normal. Haloperidol 7.5 mg/day is indicated and parkinsonism is presented. Treatment is changed to olanzapine 15mg/day with notorious improvement. Diagnostic impression: Acute polymorphic psychotic disorder with symptoms of schizophrenia

Possible causes were analyzed, finding a relationship with ivermectin treatment. This case makes evident the importance of conducting in-depht evaluations and finding risks factors for psychosis.

Childhood maltreatment (CM) is one of the best described environmental risk factors for developing any psychiatric disorder, while it also confers increased odds for obesity, cardiometabolic disorders and all-cause mortality. Inflammation has been suggested to mediate the widespread clinical effects of CM. Previously, Ligthart et al. (2016) identified a polyepigenetic signature of circulating CRP levels, a measure of chronic low-grade inflammation, that has been reliably associated with a wide array of complex disorders. The study of this biomarker could dilucidate the mechanistic relationship between CM and psychiatric outcomes.

Thus, CRP-associated epigenetic modifications were explored regarding proximal exposure to CM.

Genomic DNA was extracted from peripheral blood mononuclear cells of 157 children and adolescents (7 to 17 years old). Exposure to CM was assessed following the TASSCV criteria. Genome-wide DNA methylation was assessed by means of the EPIC array. Fifty-two out of the 58 original CRP-associated CpG sites surpassed quality control and were included in the analysis. Age, sex, psychopathological status and cell type proportions were included as covariates.

DNA methylation at 12 out of 52 CpG sites (23%) was significantly associated with exposure to CM (p < .05); 8 of these associations survived correction for multiple testing (q < .05).

This is the first study to date to explore the relationship between childhood maltreatment and an epigenetic signature of chronic low-grade inflammation. Our findings underscore the presence of immune dysregulation early after exposure to CM; further studies are needed to assess the long-term clinical implications of this signature in psychiatric patients.

Gerstmann syndrome is a rare neurological disorder that consist primarily of 4 neuropsychological signs that include acalculia (impairment in performing calcultaions), digital agnosia (dificulty discriminating their own fingers), agraphia (impairment or dificulty to write by hand); and left-right disorientation (impairment of distinguishing left from right.

Presentation of a case report of a patient with Gertsmann syndrome secondary to breast cancer metastasis.

We analyze the case of a 79 years-old female with a history of breast cancer in remission, with a severe depressive episode of 8 months of evolution, dysphoria, apathy, decrease in the ability to carry out basic activities of daily life, acute personality changes and sleep disruption. 15 days previous to the first examination the patient suffers gait disturbances, falling from her own height, memory impairment, suicide ideation and nomination aphasia.

At the examination we encounter digital agnosia, acalculia, agraphia, right-left disorientation, right hemiparesis. MRI are taken founding 3 tumor lesions in the left and right frontal lobe, 2 solid lesions with a necrotic appearance in the right parietal lobe, one of them in the angular gyrus of the parietal cortex. CT scan found a solid tumor-like lesion in the left pulmonary apex. CA-125 antigen 429.5 U/mL. She was sent to continue her treatment with oncology, receiving radiotherapy.

The psychiatric abnormalities secondary to Gerstmann syndrome make the relatives of this patient seek psychiatric care, requiring multidisciplinary work to reach an accurate diagnosis. Gerstmann syndrome is a rare neurological condition that can mimic lots of other clinical pictures.

To evaluate the attitudes of infectious diseases (ID) and critical care physicians toward antimicrobial stewardship in the intensive care unit (ICU).

Anonymous, cross-sectional, web-based surveys.

Surveys were completed in March–November 2017, and data were analyzed from December 2017 to December 2019.

ID and critical care fellows and attending physicians.

We included 10 demographic and 17 newly developed, 5-point, Likert-scaled items measuring attitudes toward ICU antimicrobial stewardship and transdisciplinary collaboration. Exploratory principal components analysis (PCA) was used for data reduction. Multivariable linear regression models explored demographic and attitudinal variables.

Of 372 respondents, 315 physicians had complete data (72% attendings, 28% fellows; 63% ID specialists, and 37% critical care specialists). Our PCA yielded a 3-item factor measuring which specialty should assume ICU antimicrobial stewardship (Cronbach standardized α = 0.71; higher scores indicate that ID physicians should be stewards), and a 4-item factor measuring value of ICU transdisciplinary collaborations (α = 0.62; higher scores indicate higher value). In regression models, ID physicians (vs critical care physicians), placed higher value on ICU collaborations and expressed discomfort with uncertain diagnoses. These factors were independently associated with stronger agreement that ID physicians should be ICU antimicrobial stewards. The following factors were independently associated with higher value of transdisciplinary collaboration: female sex, less discomfort with uncertain diagnoses, and stronger agreement with ID physicians as ICU antimicrobial stewards.

ID and critical care physicians endorsed their own group for antimicrobial stewardship, but both groups placed high value on ICU transdisciplinary collaborations. Physicians who were more uncomfortable with uncertain diagnoses reported preference for ID physicians to coordinate ICU antimicrobial stewardship; however, physicians who were less uncomfortable with uncertain diagnoses placed greater value on ICU collaborations.
