Catatonic postpartum paternal depression as a first debut of a bipolar disorder: a case report.

Paternal postpartum depression (PD) is considered an affective disorder that affects fathers during the months following childbirth. Interestingly, it has been observed that during these months the chances of a male parent suffering from depression are double that for a non-parent male counterpart. We present the case of a 34-year-old man with no relevant medical history in who, overlapping her daughter's birth, several depressive symptoms emerged, such as fatigue, lack of concentration, sleeping disturbances and abandonment of care of the newborn. Prior to consultation, patient refused to eat and open his eyes, and his speech became progressively more parsimonious until reaching mutism. The patient was diagnosed with a severe depressive disorder with catatonia. Given the lack of improvement with pharmacological treatment and due to the evidence of electroconvulsive therapy (ECT)'s effectiveness on patients with catatonia, acute ECT treatment was indicated and started. It should be noted that PD is an important entity to consider in our differential diagnosis of young parents who present a depressive episode. Few cases of relatively young patients presenting with such clinical presentation have been described and, although this case presents some of the characteristics described in the epidemiology of PD, other clinical aspects are not typical of this entity. Informed consent was obtained from the patient for the purpose of publication.

Neuropsychiatric symptoms in a patient under cystic fibrosis transmembrane conductance regulator modulators treatment: a case report.

In recent times, some research has focused on the study of potential treatments for cystic fibrosis (CF), such as cystic fibrosis transmembrane conductance regulator (CFTR) modulators. These treatments have been reported to produce neuropsychiatric symptoms in a few patients, even though there is still no clear correlation nor underlying mechanism proposed. We present the case of a 23-year-old woman with CF and no previous psychiatric history who was admitted to our inpatient psychiatric unit presenting a wide range of neuropsychiatric symptoms, such as disorganized speech, bizarre poses or persecutory delusional ideation, after going under CFTR modulators treatment. After several diagnostic tests, other possible organic causes were ruled out. Multiple antipsychotic treatments were tested during her admission, with poor tolerance and scarce response. Finally, symptomatic remission was only observed after electroconvulsive therapy was initiated. The final diagnostic hypothesis was unspecified psychosis. This case highlights the relevance of considering the possibility of neuropsychiatric symptoms appearing in patients under CFTR modulators treatment.

The polygenic basis of relapse after a first episode of schizophrenia.

Little is known about genetic predisposition to relapse. Previous studies have linked cognitive and psychopathological (mainly schizophrenia and bipolar disorder) polygenic risk scores (PRS) with clinical manifestations of the disease. This study aims to explore the potential role of PRS from major mental disorders and cognition on schizophrenia relapse. 114 patients recruited in the 2EPs Project were included (56 patients who had not experienced relapse after 3 years of enrollment and 58 patients who relapsed during the 3-year follow-up). PRS for schizophrenia (PRS-SZ), bipolar disorder (PRS-BD), education attainment (PRS-EA) and cognitive performance (PRS-CP) were used to assess the genetic risk of schizophrenia relapse.Patients with higher PRS-EA, showed both a lower risk (OR=0.29, 95% CI [0.11-0.73]) and a later onset of relapse (30.96± 1.74 vs. 23.12± 1.14 months, p=0.007. Our study provides evidence that the genetic burden of neurocognitive function is a potentially predictors of relapse that could be incorporated into future risk prediction models. Moreover, appropriate treatments for cognitive symptoms appear to be important for improving the long-term clinical outcome of relapse.

Effects of malnutrition on length of stay in patients hospitalized in an acute psychiatric ward.

INTRODUCTION: Psychiatric patients are considered at risk for malnutrition due to pharmacological treatments, lifestyle habits and the mental illness by itself. Even though metabolic risk factors have been related to worse outcomes in certain conditions, the evidence regarding the nutritional status and its impact on the length of stay in psychiatric inpatients is scarce. This study aims to characterize the nutritional status in acute psychiatric patients, to correlate it with the length of stay, and to find specific potential indicators of malnutrition. METHODS: Adult patients admitted to the Hospital Clínic of Barcelona acute psychiatric ward throughout a 1-year period were included in this cross-sectional study. Sociodemographic and clinical variables were registered, including length of stay and the nutritional status measured with the CONUT score. RESULTS: Malnutrition was observed in 42.5% of patients. Plasmatic transferrin saturation, protein and iron levels were inversely correlated with length of stay, having low iron levels an association with longer hospitalizations. The length of stay was not influenced by diagnosis or treatment. Negative correlations with the nutritional status were found in: BMI, cholesterol, triglycerides, albumin, total proteins, prealbumin, iron, lymphocytes and zinc levels, and transferrin saturation. The multivariate analysis showed a significant association for cholesterol and zinc levels, lymphocyte count, and BMI. CONCLUSIONS: Our results suggest that nutritional status might influence the course of psychiatric admissions. Cholesterol and zinc levels, lymphocyte count, and BMI might be factors strongly associated with malnutrition. This consideration might allow the identification of profiles in which lifestyle interventions could be implemented.

Exploring Digital Biomarkers of Illness Activity in Mood Episodes: Hypotheses Generating and Model Development Study.

BACKGROUND: Depressive and manic episodes within bipolar disorder (BD) and major depressive disorder (MDD) involve altered mood, sleep, and activity, alongside physiological alterations wearables can capture. OBJECTIVE: Firstly, we explored whether physiological wearable data could predict (aim 1) the severity of an acute affective episode at the intra-individual level and (aim 2) the polarity of an acute affective episode and euthymia among different individuals. Secondarily, we explored which physiological data were related to prior predictions, generalization across patients, and associations between affective symptoms and physiological data. METHODS: We conducted a prospective exploratory observational study including patients with BD and MDD on acute affective episodes (manic, depressed, and mixed) whose physiological data were recorded using a research-grade wearable (Empatica E4) across 3 consecutive time points (acute, response, and remission of episode). Euthymic patients and healthy controls were recorded during a single session (approximately 48 h). Manic and depressive symptoms were assessed using standardized psychometric scales. Physiological wearable data included the following channels: acceleration (ACC), skin temperature, blood volume pulse, heart rate (HR), and electrodermal activity (EDA). Invalid physiological data were removed using a rule-based filter, and channels were time aligned at 1-second time units and segmented at window lengths of 32 seconds, as best-performing parameters. We developed deep learning predictive models, assessed the channels' individual contribution using permutation feature importance analysis, and computed physiological data to psychometric scales' items normalized mutual information (NMI). We present a novel, fully automated method for the preprocessing and analysis of physiological data from a research-grade wearable device, including a viable supervised learning pipeline for time-series analyses. RESULTS: Overall, 35 sessions (1512 hours) from 12 patients (manic, depressed, mixed, and euthymic) and 7 healthy controls (mean age 39.7, SD 12.6 years; 6/19, 32% female) were analyzed. The severity of mood episodes was predicted with moderate (62%-85%) accuracies (aim 1), and their polarity with moderate (70%) accuracy (aim 2). The most relevant features for the former tasks were ACC, EDA, and HR. There was a fair agreement in feature importance across classification tasks (Kendall W=0.383). Generalization of the former models on unseen patients was of overall low accuracy, except for the intra-individual models. ACC was associated with "increased motor activity" (NMI>0.55), "insomnia" (NMI=0.6), and "motor inhibition" (NMI=0.75). EDA was associated with "aggressive behavior" (NMI=1.0) and "psychic anxiety" (NMI=0.52). CONCLUSIONS: Physiological data from wearables show potential to identify mood episodes and specific symptoms of mania and depression quantitatively, both in BD and MDD. Motor activity and stress-related physiological data (EDA and HR) stand out as potential digital biomarkers for predicting mania and depression, respectively. These findings represent a promising pathway toward personalized psychiatry, in which physiological wearable data could allow the early identification and intervention of mood episodes.

The Effect of Clozapine and Novel Glutamate Modulator JNJ-46356479 on Nitrosative Stress in a Postnatal Murine Ketamine Model of Schizophrenia.

Schizophrenia (SZ) is a heterogeneous mental disorder, affecting ~1% of the worldwide population. One of the main pathophysiological theories of SZ is the imbalance of excitatory glutamatergic pyramidal neurons and inhibitory GABAergic interneurons, involving N-methyl-D-aspartate receptors (NMDAr). This may lead to local glutamate storms coupled with excessive dendritic pruning and subsequent cellular stress, including nitrosative stress, during a critical period of neurodevelopment, such as adolescence. Nitrosative stress is mediated by nitric oxide (NO), which is released by NO synthases (NOS) and has emerged as a key signaling molecule implicated in SZ. Regarding glutamatergic models of SZ, the administration of NMDAr antagonists has been found to increase NOS levels in the prefrontal cortex (PFC) and ventral hippocampus (HPC). We hypothesized that suboptimal NOS function in adolescence could be a target for early treatments, including clozapine (CLZ) and the novel metabotropic glutamate receptor modulator JNJ-46356479 (JNJ). We analyzed the protein levels of NOS isoforms in adult PFC and HPC of a postnatal ketamine induced murine model of SZ receiving CLZ or JNJ during adolescence by western blot. Endothelial NOS and neuronal NOS increased under ketamine administration in PFC and decreased in CLZ or JNJ treatments. The same trends were found in the HPC in neuronal NOS. In contrast, inducible NOS was increased under JNJ treatment with respect to ketamine induction in the HPC, and the same trends were found in the PFC. Taken together, our findings suggest a misbalance of the NOS system following NMDAr antagonist administration, which was then modulated under early CLZ and JNJ treatments.

Psychotropic drug repurposing for COVID-19: A Systematic Review and Meta-Analysis.

Several psychotropic drugs, including antidepressants (AD), mood stabilizers, and antipsychotics (AP) have been suggested to have favorable effects in the treatment of COVID-19. The aim of this systematic review and meta-analysis was to collect evidence from studies concerning the scientific evidence for the repurposing of psychotropic drugs in COVID-19 treatment. Two independent authors searched PubMed-MEDLINE, Scopus, PsycINFO, and ClinicalTrials.gov databases, and reviewed the reference lists of articles for eligible articles published up to 13th December 2021. All computational, preclinical and clinical (observational and/or RCTs) studies on the effect of any psychotropic drug on Sars-CoV-2 or patients with COVID-19 were considered for inclusion. We conducted random effect meta-analyses on clinical studies reporting the effect of AD or AP on COVID-19 outcomes. 29 studies were included in the synthesis: 15 clinical, 9 preclinical, and 5 computational studies. 9 clinical studies could be included in the quantitative analyses. AD did not increase the risk of severe COVID-19 (RR= 1.71; CI 0.65-4.51) or mortality (RR=0.94; CI 0.81-1.09). Fluvoxamine was associated with a reduced risk of mortality for COVID-19 (OR=0.15; CI 0.02-0.95). AP increased the risk of severe COVID-19 (RR=3.66; CI 2.76-4.85) and mortality (OR=1.53; CI 1.15-2.03). Fluvoxamine might be a possible candidate for psychotropic drug repurposing in COVID-19 due to its anti-inflammatory and antiviral potential, while evidence on other AD is still controversial. Although AP are associated with worse COVID-19 outcomes, their use should be evaluated case to case and ongoing treatment with antipsychotics should be not discontinued in psychiatric patients.

Systematic Review of the Therapeutic Role of Apoptotic Inhibitors in Neurodegeneration and Their Potential Use in Schizophrenia.

Schizophrenia (SZ) is a deleterious brain disorder affecting cognition, emotion and reality perception. The most widely accepted neurochemical-hypothesis is the imbalance of neurotransmitter-systems. Depleted GABAergic-inhibitory function might produce a regionally-located dopaminergic and glutamatergic-storm in the brain. The dopaminergic-release may underlie the positive psychotic-symptoms while the glutamatergic-release could prompt the primary negative symptoms/cognitive deficits. This may occur due to excessive synaptic-pruning during the neurodevelopmental stages of adolescence/early adulthood. Thus, although SZ is not a neurodegenerative disease, it has been suggested that exaggerated dendritic-apoptosis could explain the limited neuroprogression around its onset. This apoptotic nature of SZ highlights the potential therapeutic action of anti-apoptotic drugs, especially at prodromal stages. If dysregulation of apoptotic mechanisms underlies the molecular basis of SZ, then anti-apoptotic molecules could be a prodromal therapeutic option to halt or prevent SZ. In fact, risk alleles related in apoptotic genes have been recently associated to SZ and shared molecular apoptotic changes are common in the main neurodegenerative disorders and SZ. PRISMA-guidelines were considered. Anti-apoptotic drugs are commonly applied in classic neurodegenerative disorders with promising results. Despite both the apoptotic-hallmarks of SZ and the widespread use of anti-apoptotic targets in neurodegeneration, there is a strikingly scarce number of studies investigating anti-apoptotic approaches in SZ. We analyzed the anti-apoptotic approaches conducted in neurodegeneration and the potential applications of such anti-apoptotic therapies as a promising novel therapeutic strategy, especially during early stages.

Identifying neurocognitive heterogeneity in Older Adults with Bipolar Disorder: a cluster analysis.

BACKGROUND: Cognitive profiles of BD patients show a demonstrated heterogeneity among young and middle-aged patients, but this issue has not yet deeply explored in Older Adults with bipolar disorder (OABD). The aim of the present study was to analyze cognitive variability in a sample of OABD. METHODS: A total of 138 OABD patients and 73 healthy controls were included in this study. A comprehensive neuropsychological assessment was administered. We performed a k-means cluster analysis method based on the neurocognitive performance to detect heterogeneous subgroups. Demographic, clinical, cognitive and functional variables were compared. Finally, univariate logistic regressions were conducted to detect variables associated with the severity of the cognitive impairment. RESULTS: We identified three distinct clusters based on the severity of cognitive impairment: (1) a preserved group (n = 58; 42%) with similar cognitive performance to HC, (2) a group showing mild cognitive deficits in all cognitive domains (n = 64; 46%) and, finally, (3) a group exhibiting severe cognitive impairment (n = 16; 12%). Older age, late onset, higher number of psychiatric admissions and lower psychosocial functioning were associated with the greatest cognitive impairment. Lower age, more years of education and higher estimated IQ were associated with a preserve cognitive functioning. LIMITATIONS: The small sample size of the severely impaired group. CONCLUSIONS: Cognitive heterogeneity remains at late-life bipolar disorder. Demographic and specific illness factors are related to cognitive dysfunction. Detecting distinct cognitive subgroups may have significant clinical implications for tailoring specific intervention strategies adapted to the level of the impairment and also to prevent cognitive decline.

[Methamphetamine use in chemsex and its consequences on mental health: a descriptive study.] / Uso de metanfetamina en el contexto chemsex y sus consecuencias en la salud mental: un estudio descriptivo.

OBJECTIVE: Chemsex is a term applicable to the use of drugs related to sex among men who have sex with men (MSM). Because it is a recent trend, there is little information about its management and consequences. The aim of the study was to describe the clinical profile of a sample of chemsex users who consulted for treatment. METHODS: This is a longitudinal and retrospective study of 53 patients who consulted for chemsex in an addiction unit of a general hospital in Barcelona, from January 2017 to June 2019. Data was collected from electronic medical records and a descriptive analysis was performed by calculating proportions and means. RESULTS: The most common drug used in chemsex was methamphetamine (81.1%; n=43) and 67.4% (n=29) of these used at least other two drugs. The prevalence of HIV infection was high (71.2%; n=37) and 72.1% (n=41) had psychiatric comorbidity, being the most common psychosis (37.2%; n=16). CONCLUSIONS: Methamphetamine was the most common drug chemsex user's seeked for treatment. Furthermore, there is a high prevalence of HIV diagnosis in this population. Both conditions can enhance the risk of suffering from psychosis and may explain why psychiatric comorbidity is so high in the sample.

OBJETIVO: El fenómeno chemsex es una práctica de consumo de sustancias asociada a las relaciones sexuales en hombres que tienen sexo con hombres. Debido a la novedad que supone, disponemos de poca información en cuanto a su abordaje y pronóstico desde el punto de vista de la salud mental. El objetivo de este estudio fue describir el perfil de una muestra de usuarios de chemsex que solicitaron tratamiento para abandonar el consumo. METODOS: Se realizó un estudio longitudinal retrospectivo de una muestra de 53 sujetos que consultaron en la unidad de adicciones de un hospital de Barcelona en el período entre enero de 2017 y junio de 2019 por consumo de drogas en contexto de chemsex. Los datos se recogieron a través de una revisión de historias clínicas y se realizó un análisis estadístico de tipo descriptivo mediante el cálculo de proporciones y medias. RESULTADOS: La metanfetamina fue la droga principal por la que más frecuentemente se solicitaba tratamiento (81,1%; n=43). De éstos, el 67,4% (n=29) consumía además, como mínimo, otras dos sustancias. El 71,2% (n=37) presentaba infección por VIH. El 72,1% (n=41) de los sujetos presentó comorbilidad psiquiátrica, siendo lo más frecuente la sintomatología psicótica (37,2%; n=16). CONCLUSIONES: Un porcentaje elevado de usuarios de chemsex presentan diagnóstico de VIH y la droga principal más utilizada y por la que más consultaron fue la metanfetamina. Ambas condiciones podrían estar relacionadas con la elevada prevalencia de sintomatología psicótica.

Psychiatric Clinical Profiles and Pharmacological Interactions in COVID-19 Inpatients Referred to a Consultation Liaison Psychiatry Unit: a Cross-Sectional Study.

The Coronavirus Disease 2019 (COVID-19) can affect mental health in different ways. There is little research about psychiatric complications in hospitalized patients with COVID-19. The aim of the study was to describe the psychiatric clinical profile and pharmacological interactions in COVID-19 inpatients referred to a Consultation-Liaison Psychiatry (CLP) unit. This is a cross-sectional study, carried out at a tertiary hospital in Spain, in inpatients admitted because of COVID-19 and referred to our CLP Unit from March 17,2020 to April 28,2020. Clinical data were extracted from electronic medical records. The patients were divided in three groups depending on psychiatric diagnosis: delirium, severe mental illness (SMI) and non-severe mental illness (NSMI). Of 71 patients included (median [ICR] age 64 [54-73] years; 70.4% male), 35.2% had a delirium, 18.3% had a SMI, and 46.5% had a NSMI. Compared to patients with delirium and NSMI, patients with SMI were younger, more likely to be institutionalized and were administered less anti-COVID19 drugs. Mortality was higher among patients with delirium (21.7%) than those with SMI (0%) or NSMI (9.45%). The rate of side effects due to interactions between anti-COVID19 and psychiatric drugs was low, mainly drowsiness (4.3%) and borderline QTc prolongation (1.5%). Patients affected by SMI were more often undertreated for COVID-19. However, the rate of interactions was very low, and avoidable with a proper evaluation and drug-dose adjustment. Half of the patients with SMI were institutionalized, suggesting that living conditions in residential facilities could make them more vulnerable to infection.
