BDNF signaling in context: From synaptic regulation to psychiatric disorders.

Brain-derived neurotrophic factor (BDNF) is a neuropeptide that plays numerous important roles in synaptic development and plasticity. While its importance in fundamental physiology is well established, studies of BDNF often produce conflicting and unclear results, and the scope of existing research makes the prospect of setting future directions daunting. In this review, we examine the importance of spatial and temporal factors on BDNF activity, particularly in processes such as synaptogenesis, Hebbian plasticity, homeostatic plasticity, and the treatment of psychiatric disorders. Understanding the fundamental physiology of when, where, and how BDNF acts and new approaches to control BDNF signaling in time and space can contribute to improved therapeutics and patient outcomes.

Discontinuation of psychotropic medication: a synthesis of evidence across medication classes.

Pharmacotherapy is an effective treatment modality across psychiatric disorders. Nevertheless, many patients discontinue their medication at some point. Evidence-based guidance for patients, clinicians, and policymakers on rational discontinuation strategies is vital to enable the best, personalized treatment for any given patient. Nonetheless, there is a scarcity of guidelines on discontinuation strategies. In this perspective, we therefore summarize and critically appraise the evidence on discontinuation of six major psychotropic medication classes: antidepressants, antipsychotics, benzodiazepines, mood stabilizers, opioids, and stimulants. For each medication class, a wide range of topics pertaining to each of the following questions are discussed: (1) Who can discontinue (e.g., what are risk factors for relapse?); (2) When to discontinue (e.g., after 1 year or several years of antidepressant use?); and (3) How to discontinue (e.g., what's the efficacy of dose reduction compared to full cessation and interventions to mitigate relapse risk?). We thus highlight how comparing the evidence across medication classes can identify knowledge gaps, which may pave the way for more integrated research on discontinuation.

Incidence of oncogenic HPV infection in women with and without mental illness: A population-based cohort study in Sweden.

BACKGROUND: Women with mental illness experience an increased risk of cervical cancer. The excess risk is partly due to low participation in cervical screening; however, it remains unknown whether it is also attributable to an increased risk of infection with human papillomavirus (HPV). We aimed to examine whether women with mental illness had an increased infection rate of HPV compared to women without mental illness. METHODS AND FINDINGS: Using a cohort design, we analyzed all 337,116 women aged 30 to 64 and living in Stockholm, who had a negative test result of 14 high-risk HPV subtypes in HPV-based screening, during August 2014 to December 2019. We defined women as exposed to mental illness if they had a specialist diagnosis of mental disorder or had a filled prescription of psychotropic medication. We identified incident infection of any high-risk HPV during follow-up and fitted multivariable Cox models to estimate hazard ratios (HR) with 95% confidence intervals (CI) for HPV infection. A total of 3,263 women were tested positive for high-risk HPV during follow-up (median: 2.21 years; range: 0 to 5.42 years). The absolute infection rate of HPV was higher among women with a specialist diagnosis of mental disorder (HR = 1.45; 95% CI [1.34, 1.57]; p < 0.001) or a filled prescription of psychotropic medication (HR = 1.67; 95% CI [1.55, 1.79]; p < 0.001), compared to women without such. The increment in absolute infection rate was noted for depression, anxiety, stress-related disorder, substance-related disorder, and ADHD, and for use of antidepressants, anxiolytics, sedatives, and hypnotics, and was consistent across age groups. The main limitations included selection of the female population in Stockholm as they must have at least 1 negative test result of HPV, and relatively short follow-up as HPV-based screening was only introduced in 2014 in Stockholm. CONCLUSIONS: Mental illness is associated with an increased infection rate of high-risk HPV in women. Our findings motivate refined approaches to facilitate the WHO elimination agenda of cervical cancer among these marginalized women worldwide.

Prolonged increase in psychotropic drug use among young women following the COVID-19 pandemic: a French nationwide retrospective study.

BACKGROUND: The COVID-19 pandemic has had a significant impact on mental health, with evidence suggesting an enduring mental health crisis. Studies worldwide observed increased usage of antidepressants, anxiolytics, and hypnotics during the pandemic, notably among young people and women. However, few studies tracked consumption post-2021. Our study aimed to fill this gap by investigating whether the surge in the number psychotropic drug consumers in France persisted 2 years after the first lockdown, particularly focusing on age and gender differences. METHODS: We conducted a national retrospective observational study based on the French national insurance database. We retrieved all prescriptions of anxiolytics, hypnotics, and antidepressants dispensed in pharmacies in France for the period 2015-2022. We performed interrupted time series analyses based on Poisson models for five age classes (12-18; 19-25; 26-50; 51-75; 76 and more) to assess the trend before lockdown, the gap induced and the change in trend after. RESULTS: In the overall population, the number of consumers remained constant for antidepressants while it decreased for anxiolytics and hypnotics. Despite this global trend, a long-term increase was observed in the 12-18 and 19-25 groups for the three drug classes. Moreover, for these age classes, the increases were more pronounced for women than men, except for hypnotics where the trends were similar. CONCLUSIONS: The number of people using antidepressants continues to increase more than 2 years after the first lockdown, showing a prolonged effect on mental health. This effect is particularly striking among adolescents and young adults confirming the devastating long-term impact of the pandemic on their mental health.

Psychotropic Medication Use and Polypharmacy Among Children and Adolescents Initiating Intensive Behavioral Therapy for Severe Challenging Behavior.

OBJECTIVE: To evaluate the prevalence, trends, and factors associated with psychotropic medication use and polypharmacy among children and adolescents initiating intensive behavioral therapy for severe challenging behavior over a 10-year period. STUDY DESIGN: In this retrospective observational study, we examined data from caregiver interviews and patient medical records on the number and types of psychotropic medications prescribed to patients initiating intensive behavioral therapy between January 1, 2013, and December 31, 2022. Trends in medication use and polypharmacy across the 10-year period were analyzed using regression analysis, while differences in demographics and clinical factors for patients with use and polypharmacy were analyzed using nonparametric statistical analysis with odds ratios presented for significant factors. RESULTS: Data from all 302 pediatric patients initiating intensive behavioral therapy across the 10-year period were analyzed. Among all patients and all years, 83.8% were taking at least 1 psychotropic medication and 68.2% experienced polypharmacy. There were no changes in the prevalence of use, mean number of medications taken, or polypharmacy across the 10-year period. Patients diagnosed with attention-deficit/hyperactivity disorder or anxiety disorder, as well as those exhibiting self-injurious behavior had higher use of psychotropic medication and polypharmacy and were taking more medications overall. CONCLUSIONS: Psychotropic medication use and polypharmacy were extremely high for children and adolescents with severe challenging behavior, but use and polypharmacy did not change over the 10-year period of data collection. Further research is needed to establish the generality of these findings to other regions of the US.

Mental health and use of psychotropic prescription drugs in adult patients with primary immune thrombocytopenia: a nationwide population-based cohort study.

Patients with primary immune thrombocytopenia (ITP) suffer from reduced survival and quality of life, but the underlying reasons for this are largely undescribed. Mental health and the use of psychotropic drugs in ITP is unknown. We investigated the risk of hospital-registered mental health events including fatigue and the use of psychotropic drugs in adult patients with ITP compared with the general population, using nationwide registry-data. We identified 3,749 patients with ITP and 149,849 age- and sex-matched general population comparators in the Danish Health Registries in the period 1997-2016. The median age was 60 years (interquartile range [IQR], 40-73) and 53% were women. We followed the individuals for incident mental health events and estimated the use of psychotropic drugs over calendar-years and in temporal relation to diagnosis of ITP. The first year cumulative incidence of any mental health event was 2.3% (95% confidence interval [CI]: 1.9-2.9) in patients and 0.7% (95% CI: 0.6-0.7) in comparators, yielding an adjusted cause-specific hazard ratio (csHR) of 3.57 (95% CI: 2.84-4.50). The corresponding estimates for depression were 1.2% (95% CI: 0.9-1.6) and 0.3% (0.3-0.4) respectively, with an adjusted csHR of 3.53 (95% CI: 2.56-4.85). We found similar findings for anxiety and fatigue, but risks generally diminished after 1-5 years. The use of opioids, antidepressants, and benzodiazepines increased in temporal relation to diagnosis of ITP. The risk of mental health events and the use of psychotropic drugs is higher in adult patients with ITP compared with the general population, and has a temporal relation to diagnosis of ITP emphasizing that mental health in ITP is a concern.

A Narrative Review on Pharmacogenomics in Psychiatry: Scientific Definitions, Principles, and Practical Resources.

PURPOSE/BACKGROUND: Pharmacogenetics (PGx) studies the genetic factors underlying interindividual variability in drug response. Only a few countries around the world are already using PGx testing in psychiatric clinical practice, whereas others are still far from adopting it. The main barrier to the clinical adoption of PGx testing seems to be the limited knowledge among psychiatrists regarding the clinical relevance of specific genetic variants to personalize therapies and the accessibility of PGx data. This review aims at further highlighting the importance of PGx-driven clinical decision making for psychotropic medications and raising psychiatrists' awareness of the value of PGx testing in psychiatry. METHODS/PROCEDURES: We summarize the genes for which substantial evidence exists about the clinical utility of integrating their PGx testing in psychiatry. Specifically, we systematically describe the functional role of clinically relevant allelic variants, their frequency across different ethnic groups, and how they contribute to classify patients in relation to their capability in metabolizing psychotropic drugs. FINDINGS/RESULTS: Briefly, clinical guidelines recommend considering PGx testing of the cytochrome class 2 C9 (CYP2C9), C19 (CYP2C19), and D6 (CYP2D6) genes and the human leukocyte antigen (HLA)-A and -B genes for several psychotropic drugs. IMPLICATIONS/CONCLUSIONS: Extensive studies have been carried out to provide a solid rationale for the inclusion of PGx testing in psychiatry. Comprehensive clinical guidelines are readily accessible to support health care providers in tailoring the prescription of psychotropic drugs based on patient's genotype information. This approach presents a tangible opportunity to significantly improve individual responses to psychiatric medications.

Clinical diagnosis of psychiatric comorbidities, performance of screening tests and pattern of psychotropic medication use in patients with chronic pancreatitis.

BACKGROUND: Psychiatric comorbidity measured by screening instruments is common in patients with chronic pancreatitis (CP) but whether this accurately reflects clinical diagnosis of psychiatric comorbidity is unknown and the prevalence of psychotropic medication prescription in CP remains largely unexplored. METHODS: Adult patients (≥18 years) with definite CP were enrolled and completed the Hospital Anxiety and Depression Scale (HADS). Demographics, clinical characteristics and medications were retrieved from case report forms and the electronic health record (EHR). Clinical diagnosis of depression or anxiety was determined by presence of ICD-10 code or inclusion in the patient's EHR problem list or treatment plan. Comparisons were made between patients with and without clinical psychiatric comorbidity. RESULTS: Total of 81 patients (48, 59.3% male; mean age 57.6 ± 14.3 years) were included. Clinical diagnoses of anxiety and depression were each noted in 47 (58%) patients, with overlap in 42 (51.9%). Compared to clinical diagnoses, the sensitivity and specificity of a positive screen for anxiety (HADS >7) were 76.6% and 91.2%; for depression 55.3% and 88.2%. Patients with anxiety and/or depression were more frequently female (51.9% v 20.7%), younger (53.6 v 64.9 years), and had alcohol etiology (51.9% v 27.6%) (all p < 0.01). In those with psychiatric comorbidity, 42 (80.8%) were prescribed psychotropic medication, most commonly gabapentinoid (24, 57.1%), selective serotonin reuptake inhibitor (n = 22, 52.4%) or benzodiazepine (n = 20, 47.6%). CONCLUSIONS: Psychiatric comorbidities are common among CP patients and many receive psychotropic medications. Further studies are needed to evaluate the impact of these medications on CP symptoms.

Temporal trends in medication and service use patterns for mental health issues among men with prostate cancer.

OBJECTIVE: Prostate cancer can significantly impact mental wellbeing, creating uncertainty and morbidity. This study described patterns of psychotropic medication and mental health service use, as a proxy measure for mental health problems, 5 years before and 5 years after prostate cancer diagnosis. METHODS: Population-based registry data were linked with Pharmaceutical Benefits Scheme and Medicare Benefits Schedule data for all prostate cancer patients diagnosed in South Australia between 2012 and 2020 (n = 13,693). We estimated the proportion and rates of psychotropic medication and mental health service use before and after diagnosis. Multivariable adjusted interrupted time series analyses (ITSA) were conducted to uncover temporal patterns. RESULTS: Fifteen percent of men commenced psychotropic medications and 6.4% sought out mental health services for the first time after diagnosis. Psychotropic medication use rose from 34.5% 5 years before to 40.3% 5 years after diagnosis, including an increase in use of antidepressants (from 20.7% to 26.0%) and anxiolytics (from 11.3% to 12.8%). Mental health service use increased from 10.2% to 12.1%, with the increase mostly being general practice mental health visits (from 7.8% to 10.6%). Multivariable ITSA indicated a significant rise in medication and service utilisation immediately before and in the first 2 years following prostate cancer diagnosis. CONCLUSION: There is a clear increase in psychotropic medication use and mental health service use around the time of prostate cancer diagnosis. Mental health outcomes of men with prostate cancer may be improved with early mental health screening, particularly during the diagnosis process, to enable early intervention.

Demographics, Symptoms, Psychotropic Use, and Caregiver Distress in Patients With Early vs Late Onset Dementia.

BACKGROUND: Understanding experiences and challenges faced by persons living with Early-Onset Dementia (EOD) compared to individuals diagnosed with Late-Onset Dementia (LOD) is important for the development of targeted interventions. OBJECTIVE: Describe differences in sociodemographic, neuropsychiatric behavioral symptoms, caregiver characteristics, and psychotropic use. DESIGN, SETTING, PARTICIPANTS: Cross-sectional, retrospective study including 908 UCLA Alzheimer's Dementia Care Program participants (177 with EOD and 731 with LOD). MEASUREMENTS: Onset of dementia was determined using age at program enrollment, with EOD defined as age <65 years and LOD defined as age >80 years. Sociodemographic and clinical characteristics were measured once at enrollment. Behavioral symptoms were measured using the Neuropsychiatric Inventory Questionnaire (NPI-Q) severity score and caregiver distress was measured using the NPI-Q distress score. Medications included antipsychotic, antidepressant, benzodiazepines and other hypnotics, antiepileptics, and dementia medications. RESULTS: EOD compared to LOD participants were more likely men, college graduates, married, live alone, and have fewer comorbidities. EOD caregivers were more often spouses (56% vs 26%, p <0.01), whereas LOD caregivers were more often children (57% vs 10%, p <0.01). EOD was associated with lower odds of being above the median (worse) NPI-Q severity (adjusted odds ratio [aOR], 0.58; 95% CI 0.35-0.96) and NPI-Q distress scores (aOR, 0.53; 95% CI 0.31-0.88). Psychotropic use did not differ between groups though symptoms were greater for LOD compared to EOD. CONCLUSION: Persons with EOD compared to LOD had sociodemographic differences, less health conditions, and fewer neuropsychiatric symptoms. Future policies could prioritize counseling for EOD patients and families, along with programs to support spousal caregivers of persons with EOD.

Impact of the early COVID-19 pandemic on adult mental health-related dispensed medications, hospitalizations and specialist outpatient visits in Norway and Sweden: Interrupted time series analysis.

AIMS: Norway and Sweden had different early pandemic responses that may have impacted mental health management. The aim was to assess the impact of the early COVID-19 pandemic on mental health-related care. METHODS: We used national registries in Norway and Sweden (1 January 2018-31 December 2020) to define 2 cohorts: (i) general adult population; and (ii) mental health adult population. Interrupted times series regression analyses evaluated step and slope changes compared to prepandemic levels for monthly rates of medications (antidepressants, antipsychotics, anxiolytics, hypnotics/sedatives, lithium, opioid analgesics, psychostimulants), hospitalizations (for anxiety, bipolar, depressive/mood, eating and schizophrenia/delusional disorders) and specialist outpatient visits. RESULTS: In Norway, immediate reductions occurred in the general population for medications (-12% antidepressants to -7% hypnotics/sedatives) except for antipsychotics; and hospitalizations (-33% anxiety disorders to -17% bipolar disorders). Increasing slope change occurred for all medications except psychostimulants (+1.1%/month hypnotics/sedatives to +1.7%/month antidepressants); and hospitalization for anxiety disorders (+5.5%/month), depressive/mood disorders (+1.7%/month) and schizophrenia/delusional disorders (+2%/month). In Sweden, immediate reductions occurred for antidepressants (-7%) and opioids (-10%) and depressive/mood disorder hospitalizations (-11%) only with increasing slope change in psychostimulant prescribing of (0.9%/month). In contrast to Norway, increasing slope changes occurred in specialist outpatient visits for depressive/mood disorders, eating disorders and schizophrenia/delusional disorders (+1.5, +1.9 and +2.3%/month, respectively). Similar changes occurred in the pre-existing mental health cohorts. CONCLUSION: Differences in early COVID-19 policy response may have contributed to differences in adult mental healthcare provision in Norway and Sweden.

Psychotherapy duration and work disability: A prospective Finnish register study.

INTRODUCTION: The influence of psychotherapy duration on common mental disorder (CMD) outcomes remains a topic of ongoing debate. Whereas most research has focused on CMD symptom change, the evidence on the psychotherapy duration of subsequent CMD-related work disability and the change in psychotropic drug purchases is scarce. METHODS: We used a register-based cohort representing 33% of the Finnish population. The participants included working-age individuals (N = 12,047, 76% women, mean age = 36) who initiated long-term psychotherapy, between 2014 and 2017. They were followed from 2011 to 2021 and psychotherapy duration ranged from less than a year to over 3 years. We used an interrupted time series design to analyze the psychotherapy duration-dependent changes in CMD-related work disability (primary outcome, operationalized as depression or anxiety-related sickness absence, SA, days) and the annual number of psychotropic drug purchases or distinct drugs purchased (secondary outcomes). RESULTS: There were no differences in the levels of work disability or drug purchases before the psychotherapy. We observed a decreasing level and trend in all outcomes across all psychotherapy duration groups. The largest decline in level was observed in the <1-year duration group (88% decline for SA and 43%-44% for drug purchases) while the smallest decline was in the 3+ years duration group (73% for SA and 27% for drug purchases). CONCLUSION: Work disability outcomes and duration varied among individuals, even with similar initial mental health-related work disability or use of auxiliary psychotropic treatments. Compared to longer psychotherapy, shorter psychotherapy was associated with sharper improvements.

Changes in Psychotropic Drug Concentrations Across the Menstrual Cycle: A Pilot Study.

BACKGROUND: The escalating prescription of psychopharmacological medications to women of reproductive age underscores the growing significance of sex-specific variations in pharmacotherapy. Despite this, clinical trials have largely overlooked these differences. Preliminary data indicate sex-specific variations in the neurobiology of affective disorders and in the metabolism, pharmacodynamics, and kinetics of therapeutic drugs. This underscores the imperative for a more nuanced exploration of menstrual cycle-dependent fluctuations in psychotropic drugs. This pilot study aimed to investigate drug and hormone fluctuations in female patients with affective disorders, aiming to enhance comprehension of the interplay between cycle-related hormone fluctuations and pharmacokinetics. The ultimate goal is to facilitate more effective and safer pharmacological therapy in the future. METHODS: Blood samples were collected from 27 patients and 27 age-matched control participants at 3 distinct time points (early follicular phase, ovulation, and late luteal phase) during each menstrual cycle. Depressive and manic symptoms were assessed, and hormone concentrations were measured in the entire sample, while drug concentrations were assessed solely in the affective disorder sample using mass spectrometry. RESULTS: Significant variations in drug concentration were observed throughout the menstrual cycle for bupropion, with a trend toward altered concentration for venlafaxine. Moreover, notable differences in hormone concentrations were identified between patients and controls, even after accounting for the impact of contraceptive use, diagnoses, and medication. CONCLUSIONS: This pilot study reinforces previously reported data, underscoring the significance of sex-specific pharmacological therapy approaches. It provides further evidence supporting the interaction among sex hormones, drugs, and symptoms of affective disorders.

Behind the Curtain: Therapeutic Drug Monitoring of Psychotropic Drugs from a Laboratory Analytical Perspective.

PURPOSE: Therapeutic drug monitoring (TDM) is a well-established tool for guiding psychopharmacotherapy and improving patient care. Despite their established roles in the prescription of psychotropic drugs, the "behind the curtain" processes of TDM requests are invariably obscure to clinicians, and literature addressing this topic is scarce. METHODS: In the present narrative review, we provide a comprehensive overview of the various steps, starting from requesting TDM to interpreting TDM findings, in routine clinical practice. Our goal was to improve clinicians' insights into the numerous factors that may explain the variations in TDM findings due to methodological issues. RESULTS: We discussed challenges throughout the TDM process, starting from the analyte and its major variation forms, through sampling procedures and pre-analytical conditions, time of blood sampling, sample matrices, and collection tubes, to analytical methods, their advantages and shortcomings, and the applied quality procedures. Additionally, we critically reviewed the current and future advances in the TDM of psychotropic drugs. CONCLUSIONS: The "behind the curtain" processes enabling TDM involve a multidisciplinary team, which faces numerous challenges in clinical routine. A better understanding of these processes will allow clinicians to join the efforts for achieving higher-quality TDM findings, which will in turn improve treatment effectiveness and safety outcomes of psychotropic agents.

Patterns and factors associated with the prescription of psychotropic medications after diagnosis of cancer in Chinese patients: A population-based cohort study.

PURPOSE: Patients with cancer may be prescribed psychotropic medications to address their psychiatric symptoms and disorders. This study examined the patterns and factors associated with the prescription of psychotropics after cancer diagnosis using a population-based database in Hong Kong. METHODS: Patients who were diagnosed with malignant cancer and had no documented psychiatric diagnosis or psychotropic medications prior to cancer diagnosis, were included. Multivariable log-binomial models were used to explore the associations between predictive factors and psychotropic medications use. RESULTS: Among 9337 patients, 1868 patients (20.0%) were newly prescribed with psychotropic medications after cancer diagnoses, most commonly hypnotics (50.3%) and antidepressants (32.8%). About one-third (31.4%) were prescribed chronic psychotropics (≥90 days). Approximately 48.3% of patients who were prescribed psychotropic medications received their prescriptions within 1 year after diagnosed with cancer. Only 18.6% of those prescribed psychotropic medications had a registered psychiatric diagnosis. Patients with multiple comorbidities (adjusted risk ratio[aRR] = 2.74; CI = 2.46-3.05) and diagnosed with oral (aRR = 1.89; CI = 1.52-2.35) or respiratory cancers (aRR = 1.62; CI = 1.36-1.93) were more likely to be prescribed psychotropics. CONCLUSIONS: The use of psychotropic medication is common (20%) among patients with cancer. Our findings highlight the importance of identification and documentation of psychiatric needs among patients with cancer.

Why do patients want medication free treatment for psychosis? An explorative study on reasons for applying to medication free programs.

BACKGROUND: A focus on patient's and service user's perspectives regarding long-term antipsychotic treatment led to a declaration from the Norwegian Ministry of Health in 2015 to offer treatment without psychotropic medication in mental health as a voluntary option in all four health care regions. In the northernmost region, a 6-bed inpatient ward unit was established, uniquely designed to give people with severe mental illness the possibility to choose such treatment. Only voluntary admissions were accepted. The aim of the present study was to explore the motivation for applying for medication free treatment among patients with several years of treatment history due to psychosis. METHOD: We performed nineteen semi-structured, in-depth interviews with persons having at least one admission at the medication free treatment ward during the period 01.01.17 - 17.10.2021. The interviews were recorded, transcribed and analysed using computer-assisted qualitative data analysis software (NVivo). Systematic Text Condensation was applied, with analysis of data from the first interview. Exploration of connections, similarities and nuances was performed through axial coding with continuous comparison of data and memo writing, followed by focused coding identifying core concepts. RESULTS: All participants had a diagnosis of severe mental illness and a history of use of antipsychotics throughout many years. The motivation to apply for medication free treatment was complex. Negative experiences with medication were described, but also positive. Many had tried to taper off before, but described this as a lonely and difficult process. Five core concepts were formed and developed from the participants' narratives: 1) Medication experiences, 2) Developing illness, 3) Treatment in general, 4) Social life and 4) Growing up. CONCLUSION: The concept of medication free treatment represents a salutogenetic hope for change, closely linked to self-efficacy and an experience of mastery. Potential conflicts concerning guidelines or evidence on medication does not come forward as important. Support from family and professionals is crucial, in contrast to the feeling of being alone when hoping for change. Motivational factors are closely linked to the concept of recovery, where interaction happens on both an individual and a structural level.

Association of Four Medication Classes and Non-suicidal Self-injury in Adolescents with Affective Disorders - A Retrospective Chart Review.

BACKGROUND: Non-suicidal self-injury (NSSI) behaviour is frequently observed in children and adolescents with psychiatric conditions. Affected individuals are regularly treated with psychotropic drugs, although the impact of these agents on NSSI behaviour remains elusive. METHODS: We performed a retrospective chart review from clinical routine data in a large cohort (N=1140) of adolescent inpatients with primary affective and non-affective psychiatric disorders according to ICD-10 (mean age=15.3±1.3 years; 72.6% female). Four separate mixed regression models compared the frequency of NSSI between treatment periods without any medication and four medication categories (benzodiazepines, selective serotonin reuptake inhibitors (SSRIs), high- and low-potency antipsychotics). RESULTS: In those individuals with affective disorders as the primary diagnosis, periods without medication were associated with significantly lower NSSI/day compared to all four other medication conditions (benzodiazepines p<10-8, antidepressants/SSRIs p=0.0004, high-potency antipsychotics p=0.0009, low-potency antipsychotics p<10 -4). In individuals with a primary diagnosis other than an affective disorder, NSSI was significantly lower during the period without medication compared to the treatment periods with benzodiazepines (p=0.005) and antidepressants/SSRIs (p=0.01). However, NSSI rates in the no-medication condition were comparable to NSSI rates under high-potency (p=0.89) and low-potency antipsychotics (p=0.53). CONCLUSIONS: The occurrence of NSSI correlates with the treatment with a psychotropic drug in children and adolescents with psychiatric disorders. Due to the retrospective design, it remains elusive to what extent psychotropic drugs might alter the frequency of NSSI in adolescents or if NSSI might indicate a transdiagnostic feature of more pronounced disease severity.

Comparable Psychotropic Prescription Rates After Hospital Discharge Between Patients with COVID-19 and Those With Non-COVID-19-Related Respiratory Infection.

INTRODUCTION: Whether psychiatric symptoms after recovery from coronavirus disease 2019 (COVID-19) are specific to this illness remains unclear. METHODS: In this retrospective study, the Diagnosis Procedure Combination data and outpatient clinic data were used for patients who received inpatient treatment in Saiseikai-affiliated hospitals for COVID-19 or other respiratory tract infections (non-COVID) from 2020 to 2022. The primary outcome was new prescriptions of psychotropic drugs after discharge (i. e., prescriptions of psychotropics to patients who had not received them before or during their hospitalization). Values of interest were compared between groups using the chi-square test or Fisher's exact test. A COX proportional-hazards model was used to examine factors associated with psychotropic prescriptions after discharge in age- and sex-matched COVID-19 and non-COVID patients. RESULTS: Of 31,993 chart records, 19,613 were excluded due to a positive history with psychiatric disorders (n=2,445), prescriptions of psychotropics (n=744), and no follow-ups (n=16,424). Thus, 3,648 COVID-19 and 8,732 non-COVID patients were included (mean [range] duration of follow-up, days: 146.9 [1-727] and 239.2 [1-729], respectively). Two hundred and four (5.6%) of the 3,648 patients with COVID-19 received psychotropic prescriptions after discharge. No statistically significant differences were observed in the prescription rates of any psychotropic category between the COVID-19 and non-COVID groups. An increase in severity during hospitalization was significantly associated with more frequent psychotropic prescriptions (hazard ratio 1.83, p<0.001). DISCUSSION: The development of psychiatric symptoms should be closely observed, especially in patients who experienced increased severity during hospitalization, regardless of whether they suffered from COVID-19.

Overview of late-onset psychoses.

BACKGROUND: Several etiologies can underlie the development of late-onset psychosis, defined by first psychotic episode after age 40 years. Late-onset psychosis is distressing to patients and caregivers, often difficult to diagnose and treat effectively, and associated with increased morbidity and mortality. METHODS: The literature was reviewed with searches in Pubmed, MEDLINE, and the Cochrane library. Search terms included "psychosis," "delusions," hallucinations," "late onset," "secondary psychoses," "schizophrenia," bipolar disorder," "psychotic depression," "delirium," "dementia," "Alzheimer's," "Lewy body," "Parkinson's, "vascular dementia," and "frontotemporal dementia." This overview covers the epidemiology, clinical features, neurobiology, and therapeutics of late-onset psychoses. RESULTS: Late-onset schizophrenia, delusional disorder, and psychotic depression have unique clinical characteristics. The presentation of late-onset psychosis requires investigation for underlying etiologies of "secondary" psychosis, which include neurodegenerative, metabolic, infectious, inflammatory, nutritional, endocrine, and medication toxicity. In delirium, psychosis is common but controlled evidence is lacking to support psychotropic medication use. Delusions and hallucinations are common in Alzheimer's disease, and hallucinations are common in Parkinson's disease and Lewy body dementia. Psychosis in dementia is associated with increased agitation and a poor prognosis. Although commonly used, no medications are currently approved for treating psychosis in dementia patients in the USA and nonpharmacological interventions need consideration. CONCLUSION: The plethora of possible causes of late-onset psychosis requires accurate diagnosis, estimation of prognosis, and cautious clinical management because older adults have greater susceptibility to the adverse effects of psychotropic medications, particularly antipsychotics. Research is warranted on developing and testing efficacious and safe treatments for late-onset psychotic disorders.

French Society for Biological Psychiatry and Neuropsychopharmacology and French-speaking Marcé Society guidelines for the management of mood disorders in women before, during, and after pregnancy.

PURPOSE: The French Society for Biological Psychiatry and Neuropsychopharmacology and the French-speaking Marcé Society have joined forces to establish expert recommendations on the prescription of psychotropic drugs before, during, and after pregnancy in women with major depressive disorder (MDD) and bipolar disorder (BD). METHODS: To elaborate recommendations, we used the RAND/UCLA Appropriateness Method, which combines scientific evidence and expert clinicians' opinions. A written survey was completed by 48 psychiatrists, who have expertise in the management of mood disorders and/or in perinatal psychiatry. Key recommendations are provided by the scientific committee based on data analysis and interpretation of the results of the survey. RESULTS: The recommendations address the following three areas that are deemed essential in women with mood disorders, with an emphasis on screening, treatment options, and monitoring: (i) management of mood disorders in women of childbearing age, (ii) management during pregnancy, (iii) management during the post-partum period. As first-line strategies, experts recommend treating mood symptoms during pregnancy and maintaining a pharmacological treatment, even in euthymic or stabilized patients. First-line options include only medications with no teratogenic risk, and during breastfeeding, only medications without evidence of adverse effects in nursing infants. CONCLUSION: The expert consensus guidelines will help facilitate treatment decisions for clinicians in the daily assessment and management of mood disorders in women of childbearing age, during pregnancy, and in the post-partum period.
