Digital Phenotypes of Mobile Keyboard Backspace Rates and Their Associations With Symptoms of Mood Disorder: Algorithm Development and Validation.

Passive sensing through smartphone keyboard data can be used to identify and monitor symptoms of mood disorders with low participant burden. Behavioral phenotyping based on mobile keystroke data can aid in clinical decision-making and provide insights into the individual symptoms of mood disorders. This study aims to derive digital phenotypes based on smartphone keyboard backspace use among 128 community adults across 2948 observations using a Bayesian mixture model. Eligible study participants completed a virtual screening visit where all eligible participants were instructed to download the custom-built BiAffect smartphone keyboard (University of Illinois). The BiAffect keyboard unobtrusively captures keystroke dynamics. All eligible and consenting participants were instructed to use this keyboard exclusively for up to 4 weeks of the study in real life, and participants' compliance was checked at the 2 follow-up visits at week 2 and week 4. As part of the research protocol, every study participant underwent evaluations by a study psychiatrist during each visit. We found that derived phenotypes were associated with not only the diagnoses and severity of depression and mania but also specific individual symptoms. Using a linear mixed-effects model with random intercepts accounting for the nested data structure from daily data, the backspace rates on the continuous scale did not differ between participants in the healthy control and in the mood disorders groups (P=.11). The 3-class model had mean backspace rates of 0.112, 0.180, and 0.268, respectively, with a SD of 0.048. In total, 3 classes, respectively, were estimated to comprise 37.5% (n=47), 54.4% (n=72), and 8.1% (n=9) of the sample. We grouped individuals into Low, Medium, and High backspace rate groups. Individuals with unipolar mood disorder were predominantly in the Medium group (n=54), with some in the Low group (n=27) and a few in the High group (n=6). The Medium group, compared with the Low group, had significantly higher ratings of depression (b=2.32, P=.008). The High group was not associated with ratings of depression with (P=.88) or without (P=.27) adjustment for medication and diagnoses. The High group, compared with the Low group, was associated with both nonzero ratings (b=1.91, P=.02) and higher ratings of mania (b=1.46, P<.001). The High group, compared with the Low group, showed significantly higher odds of elevated mood (P=.03), motor activity (P=.04), and irritability (P<.05). This study demonstrates the promise of mobile typing kinematics in mood disorder research and practice. Monitoring a single mobile typing kinematic feature, that is, backspace rates, through passive sensing imposes a low burden on the participants. Based on real-life keystroke data, our derived digital phenotypes from this single feature can be useful for researchers and practitioners to distinguish between individuals with and those without mood disorder symptoms.

Mapping a psychosocial syndemic among methamphetamine-using sexual minority men living with HIV.

While research with sexual minority men (SMM) has focused on disparities related to HIV, substance use and mental health, synergistic psychosocial pathways driving these epidemics remain underexplored. We used syndemic theory to assess how psychosocial factors sustain methamphetamine use and hinder recovery efforts for SMM living with HIV. A triangulation of network analyses and constructivist grounded theory approaches is utilised to elucidate pathways through which psychosocial factors influence methamphetamine use among this population. Survey data (N = 129) are used for quantitative analyses and a purposive sub-sample (n = 24) was recruited for semi-structured interviews for qualitative analyses. The network analysis revealed two statistically significant bivariate associations: between post-traumatic stress disorder and depression symptoms (b = 0.37, SD = 0.07, 95% confidence interval [0.23, 0.49]) and between depression symptoms and negative affect (b = 0.26, SD = 0.07, 95% confidence interval [0.12, 0.38]). Findings from the constructivist grounded theory analysis supplement the network analysis by offering a nuanced take on how negative affect, post-traumatic stress disorder, and depression symptoms operate synergistically to promote methamphetamine use and impede recovery efforts. Participants relay experiences of using methamphetamine to cope with these psychosocial factors through avoidance, escapism, mood elevation, and numbing of emotions. Findings suggest that centring these psychosocial factors may inform more effective, holistic interventions for this high-priority population.

Exploring perspectives on engagement in interactive virtual reality for chronic pain management: insights from a content analysis study

To investigate perspectives of people with chronic pain regarding aspects of immersive virtual reality (IVR) that enhance and reduce engagement and the outcomes of engagement in IVR. This content analysis was performed on data obtained through open-ended interview questions from a study aiming to understand the influence of IVR on chronic pain study at a research lab at a university. Participants included a sample of 20 adults who completed the parent study. Results highlight that presence, agency, customization, and novelty are important aspects that enhance engagement in IVR, with agency and presence being mentioned most frequently. Meanwhile, secondary effects of IVR and usability were said to reduce engagement with the IVR. Outcomes of engagement with IVR include enjoyment, mood elevation, relaxation/calming, a distraction from pain, and a loss of reality. This study provides an initial understanding of individuals’ perspectives of engagement with IVR in relation to chronic pain management. Health professionals using IVR to treat people with chronic pain can use these elements to facilitate engagement in their clients. Further research should be done to study the association between engagement in IVR and pain reduction to improve the development of IVR programs for chronic pain management.

Effects of Recreational Therapy on Anxiety Levels in Patients with Chronic Illness

Purpose: The aim of the study was to assess the effects of recreational therapy on anxiety levels in patients with chronic illness. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: The study indicated that engaging in recreational activities, such as art, music, and physical exercise, can significantly alleviate anxiety symptoms. These activities provide a distraction from pain and discomfort, enhance mood, and promote relaxation. For instance, studies have demonstrated that music therapy can lead to decreased levels of cortisol, the stress hormone, and increased production of endorphins, which are natural mood elevators. Similarly, physical activities like yoga and tai chi help in reducing tension and improving overall mental health by fostering a sense of physical well-being and empowerment. Art therapy, through creative expression, allows patients to process their emotions and experiences, leading to reduced feelings of anxiety and depression. Overall, recreational therapy offers a holistic approach to managing anxiety in chronically ill patients, contributing to improved quality of life and better mental health outcomes. Implications to Theory, Practice and Policy: Cognitive-behavioral theory, biopsychosocial model and flow theory may be used to anchor future studies on assessing the effects of recreational therapy on anxiety levels in patients with chronic illness. Practitioners should consider combining different types of recreational therapies to maximize therapeutic benefits. Policymakers should recognize the value of recreational therapy and integrate it into national healthcare guidelines and policies. This integration can promote the widespread adoption of these therapies in various healthcare settings, ensuring that patients with chronic illnesses have access to comprehensive care options.

Change in Depressive Symptoms and Longitudinal Regional Amyloid Accumulation in Unimpaired Older Adults

Depressive symptoms in older adults may be a harbinger of Alzheimer disease (AD), even in preclinical stages. It is unclear whether worsening depressive symptoms are manifestations of regional distributions of core AD pathology (amyloid) and whether cognitive changes affect this relationship. To evaluate whether increasing depressive symptoms are associated with amyloid accumulation in brain regions important for emotional regulation and whether those associations vary by cognitive performance. Participants from the Harvard Aging Brain Study, a longitudinal cohort study, underwent annual assessments of depressive symptoms and cognition alongside cortical amyloid positron emission tomography (PET) imaging at baseline and every 2 to 3 years thereafter (mean [SD] follow-up, 8.6 [2.2] years). Data collection was conducted from September 2010 to October 2022 in a convenience sample of community-dwelling older adults who were cognitively unimpaired with, at most, mild baseline depression. Data were analyzed from October 2022 to December 2023. Depression (Geriatric Depression Scale [GDS]-30-item), cognition (Preclinical Alzheimer Cognitive Composite-5 [PACC]), and a continuous measure of cerebral amyloid (Pittsburgh compound B [PiB] PET) examined in a priori-defined regions (medial orbitofrontal cortex [mOFC], lateral orbitofrontal cortex, middle frontal cortex [MFC], superior frontal cortex, anterior cingulate cortex, isthmus cingulate cortex [IC], posterior cingulate cortex, and amygdala). Associations between longitudinal GDS scores, regional amyloid slopes, and PACC slopes were assessed using linear mixed-effects models. In this sample of 154 individuals (94 [61%] female; mean [SD] age, 72.6 [6.4] years; mean (SD) education, 15.9 [3.1] years), increasing PiB slopes in the bilateral mOFC, IC, and MFC were associated with increasing GDS scores (mOFC: β = 11.07 [95% CI, 5.26-16.87]; t = 3.74 [SE, 2.96]; P = .004; IC: β = 12.83 [95% CI, 5.68-19.98]; t = 3.51 [SE, 3.65]; P = .004; MFC: β = 9.22 [95% CI, 2.25-16.20]; t = 2.59 [SE, 3.56]; P = .03). Even with PACC slope as an additional covariate, associations remained significant in these regions. In this cohort study of cognitively unimpaired older adults with, at most, mild baseline depressive symptoms, greater depressive symptoms over time were associated with amyloid accumulation in regions associated with emotional control. Furthermore, these associations persisted in most regions independent of cognitive changes. These results shed light on the neurobiology of depressive symptoms in older individuals and underscore the importance of monitoring for elevated mood symptoms early in AD.

Journeying with a bipolar disorder: The quest plot.

Many with a bipolar disorder embark on a quest, most commonly during elevated mood states, and sometimes driven by a prescient delusion. This essay draws a parallel with a prominent literary plot - the Quest. Reference to the literary plot is made and an exemplar provided, being based on the personal stories of several patients. Parallels between the literary model and the current vignette are emphasized. Manic prescience can sometimes be more than a delusion. The Quest is both a literary plot and at times may underlie manic behaviours and even illustrate its symbolic value.

Peculiarities of Stepan Budnyi’s Artistic Works: Song and Musical Aspects

The poetic, prose and memoir works of Ukrainian writer Stepan Budnyi are considered in the article. He has left a noticeable mark in the history of Ukrainian literature of the 1950s. The focus of the research includes the analysis of the song concept, used frequently by the author and designated as a genre (in his own works). Many poetic works of S. Budnyi, characterized by melodiousness, emotionally elevated mood, simplicity of expression, vivid imagery, and the presence of striking figurative details, have a musical orientation. The frequency of the poet’s use of the song lexeme is counted in the article, indicating the folk-song character of S. Budnyi’s entire poetic heritage. This is reflected particularly in the titles of poetic works, evoking musical associations simultaneously. The poet has preferred those poetic works containing musical terminology in his translations from various languages. It is revealed that S. Budnyi’s relatively small prose heritage also includes musical motifs. Similar to poetry, the song in the writer’s prose works holds a distinct place and is a leading motif throughout his entire creative output. The author’s position and understanding of the essence of beauty are traced through the expressions of the lyrical heroes in prose sketches about music, song and dance. The author’s appeals to song and music are also considered in the writer’s epistolary. Texts by S. Budnyi, set to music by various Ukrainian composers such as Yaroslav Vyshyvanyi, Oleh Herman, Bohdan Klymchuk, Bohdan and Ivan Kravchuk brothers, Faina Moldavska, Volodymyr Obukhivskyi, Mykhailo Obleshchuk, Andrii Plishka, and others, are distinguished. Attention is drawn to the linguistic features of the writer’s artistic works, emphasizing especially that the author’s neologisms, used frequently, imbue the texts with a peculiar musicality. In general, Stepan Budnyi’s poetry has an original sound, impressing with a variety of artistic means, especially the vivid metaphorical expressions.

Butyrate- and Beta-Hydroxybutyrate-Mediated Effects of Interventions with Pro- and Prebiotics, Fasting, and Caloric Restrictions on Depression: A Systematic Review and Meta-Analysis.

To examine the butyrate- and beta-hydroxybutyrate (BHB)-modulated effects of pre- and probiotic interventions, fasting, and caloric restriction interventions, a systematic literature review was carried out with a subsequent meta-analysis. Three pre-and probiotic intervention randomized control trials (RCTs) were included in the meta-analysis. A significant increase in butyrate (standardized mean difference (SMD) [confidence interval (CI)] 0.34; [0.02-0.67]) and an improvement in depression scores (SMD [CI] 0.15, [-0.35-0.70]) through pre- and probiotic interventions were shown in the meta-analysis. The intervention duration of the included studies ranged from three days to four weeks, with the examined population being healthy adults. Butyrate was measured in either plasma or feces, and the depression score was obtained under the Swedish core affect scale, the hospital anxiety and depression scale (HADS), or the depression, anxiety, and stress scale-21 items (DASS-21). In addition to butyrate, the total SCFA concentration also seems to be positively associated with pre- and probiotic administration (SMD [CI] 0.55 [0.15-0.95]). Despite the significant short-chain fatty acid (SCFA) and butyrate concentration changes, no significant correlation between butyrate and depression or between SCFAs and depression could be shown through linear regression models. Nevertheless, the regression coefficient b1 = 1.57 (p = 0.17) for butyrate suggests a strong, positive connection between butyrate and depression. Additionally, three studies were qualitatively analyzed, examining fasting as an intervention and revealing a connection between fasting, BHB, and depression. The association between fasting, BHB, and depression or mood elevation appeared to be related to BHB concentrations, which may be due to the similar biochemical properties of BHB and butyrate. Furthermore, caloric restrictions as alternatives to fasting were proposed as potential long-term interventions.

Post-Stroke Mania- A Case Series

Background: Post-stroke mania is a complex neuropsychiatric phenomenon that poses challenges in both diagnosis and management. This paper presents a detailed analysis of three distinct cases, comprising two females and one male, each exhibiting post-stroke mania following cerebrovascular events. Our study aims to provide insights into the varied clinical presentations, contributing factors, and therapeutic interventions in this unique subset of stroke survivors. Case 1: A 71-year-old female experienced a left hemispheric stroke, subsequently displaying manic symptoms characterized by elevated mood, impulsivity, and increased energy. Neuroimaging revealed damage to the parieto-occipital lobe, prompting further exploration into the neural correlates of post-stroke mania. Case 2: A 51-year-old female presented with right hemiparesis. Shortly after the stroke, he manifested manic features, including decreased need for sleep and heightened irritability. Psychosocial factors and pharmacological interventions were investigated to better understand the interplay of biological and environmental influences. Case 3: A 55-year-old male suffered a left hemispheric stroke. Poststroke, she exhibited manic symptoms such as distractibility and excessive goal-directed activity. The impact of lesion location on the manifestation of post-stroke mania was explored in this case. Conclusion: Through a comprehensive analysis of these cases, we aim to contribute to the growing body of literature on post-stroke mania, shedding light on its clinical heterogeneity and paving the way for tailored treatment approaches. Recognizing the nuanced nature of post-stroke mania is crucial for healthcare providers to optimize care strategies and improve the quality of life for stroke survivors grappling with this challenging neuropsychiatric condition

Alterations in brain network connectivity and subjective experience induced by psychedelics: a scoping review.

Intense interest surrounds current research on psychedelics, particularly regarding their potential in treating mental health disorders. Various studies suggest a link between the subjective effects produced by psychedelics and their therapeutic efficacy. Neuroimaging evidence indicates an association of changes in brain functional connectivity with the subjective effects of psychedelics. We conducted a review focusing on psychedelics and brain functional connectivity. The review focused on four psychedelic drugs: ayahuasca, psilocybin and LSD, and the entactogen MDMA. We conducted searches in databases of MEDLINE, Embase, APA PsycInfo and Scopus from inception to Jun 2023 by keywords related to functional connectivity and psychedelics. Using the PRISMA framework, we selected 24 articles from an initial pool of 492 for analysis. This scoping review and analysis investigated the effects of psychedelics on subjective experiences and brain functional connectivity in healthy individuals. The studies quantified subjective effects through psychometric scales, revealing significant experiences of altered consciousness, mood elevation, and mystical experiences induced by psychedelics. Neuroimaging results indicated alterations in the functional connectivity of psychedelics, with consistent findings across substances of decreased connectivity within the default mode network and increased sensory and thalamocortical connectivity. Correlations between these neurophysiological changes and subjective experiences were noted, suggesting a brain network basis of the psychedelics' neuropsychological impact. While the result of the review provides a potential neural mechanism of the subjective effects of psychedelics, direct clinical evidence is needed to advance their clinical outcomes. Our research serves as a foundation for further exploration of the therapeutic potential of psychedelics.

Striatal Functional Alterations Link to Distinct Symptomatology Across Mood States in Bipolar Disorder

BackgroundAs a central hub in cognitive and emotional brain circuits, the striatum is considered likely to be integrally involved in the psychopathology of bipolar disorder (BD). However, it remains unclear how alterations in striatal function contribute to distinct symptomatology of BD during different mood states. MethodsBehavioral assessment (i.e., emotional symptoms and cognitive performance) and neuroimaging data were collected from 125 participants comprising 31 (hypo)manic, 31 depressive, and 31 euthymic patients with BD, and 32 healthy control participants. We compared the functional connectivity (FC) of striatal subregions across BD mood states with healthy control participants and then used a multivariate data-driven approach to explore dimensional associations between striatal connectivity and behavioral performance. Finally, we compared the FC and behavioral composite scores, which reflect the individual weighted representation of the associations, among different mood states. ResultsPatients in all mood states exhibited increased FC between the bilateral ventral rostral putamen and ventrolateral thalamus. Bipolar (hypo)mania uniquely exhibited increased ventral rostral putamen connectivity and superior ventral striatum connectivity. One latent component was identified, whereby increased FCs of striatal subregions were associated with distinct psychopathological symptomatology (more manic symptoms, elevated positive mood, less depressive symptoms, and worse cognitive performance). Patients with bipolar (hypo)mania had the highest FC and behavioral composite scores while bipolar patients with depression had the lowest scores. ConclusionsOur data demonstrated both trait features of BD and state features specific to bipolar (hypo)mania. The findings underscored the fundamental role of the striatum in the pathophysiological processes underlying specific symptomatology across all mood states.

Ghrelin is associated with an elevated mood after an overnight fast in depression

BackgroundMajor depressive disorder (MDD) comprises subtypes with distinct symptom profiles. For example, patients with melancholic and atypical MDD differ in the direction of appetite and body weight changes as well as mood reactivity. Despite reported links to altered energy metabolism, the role of circulating neuropeptides from the gut in modulating such symptoms remains largely elusive. MethodsWe collected data from 103 participants, including 52 patients with MDD and 51 healthy control participants (HCP). After an overnight fast, we measured plasma levels of (acyl and des-acyl) ghrelin and participants reported their current metabolic and mood states using visual analog scales (VAS). Furthermore, they completed symptom-related questionnaires (i.e., STAI-T). ResultsPatients with atypical versus melancholic MDD reported less negative affect (p = 0.025). Higher levels of acyl ghrelin (corrected for BMI) were associated with improved mood (p = 0.012), specifically in patients with MDD. These associations of ghrelin were not mood-item specific and exceeded correlations with trait markers of negative affectivity. In contrast to associations with mood state, higher levels of ghrelin were not associated with increased hunger per se or changes in appetite in patients with MDD. LimitationsThe study is limited by the cross-sectional design without an intervention. ConclusionsOur results reveal potentially mood-enhancing effects of ghrelin in fasting individuals that exceed associations with metabolic state ratings. These associations with circulating neuropeptides might help explain anti-depressive effects of fasting interventions and could complement conventional treatments in patients with melancholic MDD.

Lithium Intoxication with Therapeutic Doses Following Laparoscopic Sleeve Gastrectomy: A Case Report and Review of the Literature

Introduction Lithium is a mood stabilizer often used as a first-line treatment for bipolar disorder. Its narrow therapeutic window and changes in the absorption, distribution, and elimination of the drug following bariatric surgery have important implications regarding patient safety.ObjectivesWe present a 51-year-old female patient with bipolar disorder and a medical history of morbid obesity, type 2 diabetes mellitus, hypothyroidism, hyperlipidemia, and essential hypertension. She was mentally stable on lithium 1200 mg/day, valproate 500 mg/day, and quetiapine 400 mg/day. She had undergone laparoscopic sleeve gastrectomy. After a month, she showed up to the emergency room (ER) with nausea, vomiting, diarrhea, and fatigue. Gastroenteritis was suspected until the patient started showing neurological symptoms such as delirium, dysarthria, ataxia, chorea, and athetosis.MethodsThe patient was monitored and received aggressive intravenous hydration (3000 cc of 0.9% serum isotonic) in the intensive care unit (ICU). She was prescribed intramuscular biperiden injection of 5 mg/ml/day, pheniramine 45.5 mg/2 ml/day, and lorazepam 1 mg/day. Her lithium levels were checked every six hours. She was agitated and disoriented for the first five days despite lithium levels being in the therapeutic range. On day six, her blood lithium levels dropped to 0.399 mmol/L. Her psychiatric examination revealed that she resumed cooperation and orientation, her dysarthria subsided. However, her thought content and attitude were grandiose, and she had a labile affect. We prescribed 5 mg/day of olanzapine routinely and 1 mg/day of lorazepam on a needed basis. The next day, her labile affect became calmer, and her sleep improved so she was discharged from the ICU and admitted to general surgery inpatient service, and olanzapine was titrated to 10 mg per day since she had elevated mood symptoms.ResultsAfter 7 days of intravenous hydration and supportive treatment, her neurological symptoms completely subsided except for a fine tremor, which lasted for another 3 days and then ceased. She was clinically stabilized without further need for intervention. Her lithium level was 0.206 mmol/L before her discharge.Conclusions We believe it is of utmost importance to build a consensus in guidelines and inform physicians about lithium toxicity and its symptoms after bariatric surgeries. We recommend a careful follow-up of the patient pre-and postoperatively. Preoperative psychiatric intervention includes decreasing the lithium dose gradually and discontinuing it. After the operation, lithium can be started with a much lower dose and may be increased by checking lithium levels every week for at least 6 weeks after the operation until the patient can digest solid food again, and then every 2 weeks for 6 months, and thereafter every month for one year.Disclosure of InterestNone Declared

Kambó as a drug that can induce psychotic or manic symptoms. A case report

IntroductionKambó, also known as the “frog medicine,” is a traditional Amazonian medicine derived from the secretions of the Phyllomedusa bicolor tree frog. It has gained global attention for its purported therapeutic properties, including its use in addressing mental health issues. However, the psychiatric effects of kambó remain poorly understood, particularly concerning manic symptoms or psychosis.Objectives The primary objective of this review is to comprehensively analyze and evaluate the available literature regarding the connection between kambó use and psychosis or manic symptoms. Specifically, this review seeks to determine the prevalence of psychosis among kambó users, identify potential risk factors for the development of psychosis or manic symptoms in this context, explore the mechanisms underlying any observed psychiatric effects, and provide insights into the clinical implications of kambó use.MethodsA case report of a 34-year-old man with chronic delusional disorder who presented to the emergency department with manic symptoms coinciding in time with the use of Kambó.ResultsThe findings of this bibliographical review suggest that there is limited empirical evidence to establish a direct link between kambó use and psychosis. Most available studies are anecdotal or based on qualitative reports, making it challenging to draw definitive conclusions. While some case reports and interviews suggest that kambó use may be associated with transient psychotic-like symptoms, including visual and auditory hallucinations, more rigorous research is needed to confirm and characterize these effects. Several case reports and qualitative studies suggest that individuals who have undergone kambó ceremonies may experience transient manic-like symptoms, such as elevated mood, increased energy, and impulsivity. However, these reports lack systematic assessment and standardized measurement of manic symptoms. Mechanisms underlying these effects remain speculative, with some researchers proposing altered neurotransmitter systems as a potential explanation.Conclusions In conclusion, this review underscores the scarcity of scientific literature on the potential association between kambó use and psychosis or maniac symptoms. Although anecdotal reports and qualitative studies suggest a link, there is a notable lack of robust empirical research to support or refute this claim. Future research should focus on conducting controlled studies to elucidate the psychiatric effects of kambó, including its potential to induce psychosis and maniac symptoms, while also considering cultural and individual factors that may influence outcomes. Such research would contribute to a more comprehensive understanding of kambó’s psychopharmacological profile and its implications for mental health.Disclosure of InterestNone Declared

Atypical case of anterograde amnesia after cerebral infarction and anti-NMDA encephalitis post Covid 19 infection: A complex clinical case

IntroductionOnly a few cases of primary anterograde amnesia with confabulation after severe complex brain damage have been described in the literature.ObjectivesTo describe a case of anterograde amnesia with confabulation in a patient with severe and extensive brain damage.Methodscase reportResultsCase presentation: A 48-year-old male patient with a medical history of diabetes mellitus type II, hypertension, presented to a psychiatric clinic for the first time. He was admitted to the hospital due to the manifestation of disruptive aggressive behaviour, aimless wandering, and excessive, impulsive expenditure of financial resources. At the time of hospitalization and during the hospital stay, the patient exhibited a state of elevated mood and anterograde amnesia compounded by the presence of prominent confabulation, easily irritable mood with a tendency to conflict. No physical limitations.Background: The patient is an active long-distance driver for 15 years. A year before hospitalization in psychiatric clinic, he was travelling to Moscow, he had episode of headache and unconsciousness after which hospitalization. Diagnosed with multiple infarcts of embolic origin in the right frontal lobes, both cortical and subcortical, on the right side at the level of the uncus, in the medial anterior parts of the right occipital lobe, on the left side in the insula and at the level of the capsula externa, in the anterior basal part of the left temporal lobe. After hemodynamic stabilization, he was repatriated to Latvia. Stationary positive SARS-CoV-2 PCR, O2 support therapy required. The patient develops auditory and visual hallucinations, which do not correct on antipsychotic therapy. Lumbar puncture was performed, which showed positive anti-NMDA antibodies, magnetic resonance - autoimmune limbic encephalitis with damage to the gyrus cinguli of the insula cortex of both temporal lobes and the right subfrontal part with spread throughout the right temporal lobe, bilaterally in the mediobasal structures of the temporal lobes and the right thalamus with progressive changes. The patient receives immunomodulatory therapy, plasma exchange and immune globulin. Hallucinations decrease on the background of therapy. At discharge - moderate ataxia in the legs, disorientation in time, severe short-term memory disorders.The patient in his mind lives like nothing has happened and the same life continues.Image:Image 2:ConclusionsThe long-term prognosis for the patient remains uncertain, given the multifaceted nature of the condition and the extent of brain damage. Continuous monitoring, rehabilitation, and ongoing support will be essential to assess cognitive recovery and improve the patient’s quality of life.Disclosure of InterestNone Declared

Aerobic Exercise and Endocannabinoids: A Narrative Review of Stress Regulation and Brain Reward Systems.

Aerobic exercise is a widely adopted practice, not solely for enhancing fitness and reducing the risk of various diseases but also for its ability to uplift mood and aid in addressing depression and anxiety disorders. Within the scope of this narrative review, we seek to consolidate current insights into the endocannabinoid-mediated regulation of stress and the brain's reward mechanism resulting from engaging in aerobic exercise. A comprehensive search was conducted across Medline, SPORTDiscus, Pubmed, and Scopus, encompassing data available until November 30, 2023. This review indicates that a bout of aerobic exercise, particularly of moderate intensity, markedly augments circulating levels of endocannabinoids-N-arachidonoyl-ethanolamine (AEA) and 2-acylglycerol (2-AG), that significantly contributes to mood elevation and reducing stress in healthy individuals. The current understanding of how aerobic exercise impacts mental health and mood improvement is still unclear. Moderate and high-intensity aerobic exercise modulatesstress through a negative feedback mechanism targeting both the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic nervous system, thereby facilitating stress regulation crucial role in endocannabinoid synthesis, ultimately culminating in the orchestration of negative feedback across multiple tiers of the HPA axis, coupled with its influence over cortical and subcortical brain structures. The endocannabinoid has been observed to govern the release of neurotransmitters from diverse neuronal populations, implying a universal mechanism that fine-tunes neuronal activity and consequently modulates both emotional and stress-related responses. Endocannabinoids further assume a pivotal function within brain reward mechanisms, primarily mediated by CB1 receptors distributed across diverse cerebral centers. Notably, these endocannabinoids partake in natural reward processes, as exemplified in aerobic exercise, by synergizing with the dopaminergic reward system. The genesis of this reward pathway can be traced to the ventral tegmental area, with dopamine neurons predominantly projecting to the nucleus accumbens, thereby inciting dopamine release in response to rewarding stimuli.

Mental health outcomes and suicidality in hospitalized transgender adolescents: A propensity score-matched Cross-sectional analysis of the National inpatient sample 2016–2018

Transgender adolescents have unique mental health needs. This demographic has increased rates of mood disorders, anxiety, and depression compared to their cisgender peers. Large-scale studies focused on mental health outcomes, including suicidality, in the transgender adolescent population remain unknown. This study tries to fill these gaps in the literature.Data for this study was taken from the National Inpatient Sample 2016–2018. Transgender adolescents were identified using the ICD-10 codes related to transsexualism diagnoses. These individuals were compared to adolescents without transsexualism diagnoses. To mitigate imbalances in baseline characteristics, we utilized a 1:2 nearest neighbor propensity score matching with a caliper width of 0.0001, considering variables such as age, year of hospitalization, and psychiatric disorders. Following propensity score matching, the study cohort comprised 2635 transgender and 5270 non-transgender adolescents (Mean age 15.2 years). The transgender group demonstrated a notably higher prevalence of mood disorders (91%) and anxiety disorders (65%). Furthermore, the prevalence of suicidal ideation was significantly higher in the transgender group (52.4% vs. 39.2%, p < 0.001). However, there was no significant difference in the prevalence of suicide attempts between the groups. After controlling for psychiatric comorbidities, age, and gender, the odds ratio for the composite outcome of suicidal ideation or attempt was 1.99 (95% CI 1.58–2.12, p < 0.001).Our study identifies elevated mood and anxiety disorders and suicidality rates in hospitalized transgender adolescents compared to cisgender peers. Mood disorders notably amplify the risk of suicidal attempts. These findings urgently call for targeted mental health interventions and policy changes to serve this vulnerable population in healthcare settings better.

Daydreaming and grandiose delusions: development of the Qualities of Daydreaming Scale.

Daydreaming may contribute to the maintenance of grandiose delusions. Repeated, pleasant and vivid daydreams about the content of grandiose delusions may keep the ideas in mind, elaborate the details, and increase the degree of conviction in the delusion. Pleasant daydreams more generally could contribute to elevated mood, which may influence the delusion content. We sought to develop a brief questionnaire, suitable for research and clinical practice, to assess daydreaming and test potential associations with grandiosity. 798 patients with psychosis (375 with grandiose delusions) and 4518 non-clinical adults (1788 with high grandiosity) were recruited. Participants completed a daydreaming item pool and measures of grandiosity, time spent thinking about the grandiose belief, and grandiose belief conviction. Factor analysis was used to derive the Qualities of Daydreaming Scale (QuOD) and associations were tested using pairwise correlations and structural equation modelling. The questionnaire had three factors: realism, pleasantness, and frequency of daydreams. The measure was invariant across clinical and non-clinical groups. Internal consistency was good (alpha-ordinals: realism=0.86, pleasantness=0.93, frequency=0.82) as was test-retest reliability (intra-class coefficient=0.75). Daydreaming scores were higher in patients with grandiose delusions than in patients without grandiose delusions or in the non-clinical group. Daydreaming was significantly associated with grandiosity, time spent thinking about the grandiose delusion, and grandiose delusion conviction, explaining 19.1, 7.7 and 5.2% of the variance in the clinical group data, respectively. Similar associations were found in the non-clinical group. The process of daydreaming may be one target in psychological interventions for grandiose delusions.

Herbal Approach in Premenstrual Syndrome – A Review

Premenstrual Syndrome (PMS) is a common phenomenon experienced by many women in the days leading up to their menstrual cycle. The physical and emotional symptoms can range from mild discomfort to severe disruptions in daily life. While conventional treatments exist, an increasing number of individuals are turning to herbal approaches to find relief from PMS symptoms such as Chaste Tree (Vitex agnus-castus), Evening Primrose Oil (Oenothera biennis), Dong Quai (Angelica sinensis), Ginger (Zingiber officinale), In addition to herbal remedies, lifestyle and dietary adjustments play a crucial role in managing PMS. A diet rich in whole foods, particularly fruits, vegetables, and whole grains, can contribute to overall well-being. Regular exercise has been shown to reduce PMS symptoms by promoting circulation and releasing endorphins, the body's natural mood elevators. The herbal approach to managing PMS offers a natural and holistic alternative for women seeking relief from the challenges of premenstrual syndrome. While individual responses to herbal remedies may vary, many women find comfort and support in the wisdom of nature.

How Physicians and Nursing Staff Perceive Effectiveness and Tolerability of Bryophyllum Preparations: An Online Survey in an Anthroposophic Hospital

Background: Bryophyllum preparations are widely used in anthroposophic medicine, most often for mental and behavioural disorders. Three prospective studies have revealed positive effects of Bryophyllum pinnatum on sleep quality, and various trials have shown very good tolerability. Results from animal models have indicated CNS depressant and anxiolytic effects. This survey was conducted at the hospital “Klinik Arlesheim” in Switzerland to find out how the physicians and the nursing staff perceive the effectiveness and the tolerability of the Bryophyllum preparations they most frequently use. Design: Internal, anonymous online survey of healthcare professionals (April 8–May 31, 2022). The questionnaire comprised 105 multiple-choice questions. Answering the questions was taken as consent to participate in the survey. Participants and Methods: All physicians and nursing staff with a valid email address at the hospital “Klinik Arlesheim AG” were invited via email to participate in this REDCap survey. The data were analysed descriptively. Results: Out of 266 invited participants, 48 answered some and 36 answered all questions (response rate between 18.0% and 13.5%). The participants had long experience with Bryophyllum preparations and were comprised approximately equal numbers of physicians and nursing staff. Various Bryophyllum preparations from the hospital’s own production and Wala Heilmittel GmbH (in both cases produced from the species B. daigremontianum) and from Weleda AG (species B. pinnatum) were used. The indications for which most participants had prescribed or administered Bryophyllum preparations “very frequently” were anxiety, sleep disorders, crisis situations in oncology, posttraumatic stress disorder, benzodiazepine dependence/withdrawal, and depression. Improvements such as relief from restlessness, decreased anxiety, balance, easier falling asleep, better sleeping through, increased resilience, mood elevation, and less urge to move one’s legs were reported “frequently” or “very frequently.” Almost all participants agreed that Bryophyllum can be used to reduce the intake of synthetic sedatives or psychotropic drugs, but only approximately half believed that it could replace them. The majority of participants mentioned good tolerability of the various products, but a few reported occasional stomach or intestinal irritation, daytime fatigue, drowsiness, diarrhoea, and nausea. Conclusion: Bryophyllum preparations are perceived as helpful in the treatment of various mental disorders, particularly anxiety, and are generally well tolerated. Most of these preparations are used for indications that have not yet been clinically investigated.
