Background and Purpose: Antipsychotics such as olanzapine are associated with significant metabolic dysfunction, attributed to gut microbiome dysbiosis. A recent notion that most psychotropics are detrimental to the gut microbiome has arisen from consistent findings of metabolic adverse effects. However, unlike olanzapine, the metabolic effects of lurasidone are conflicting. Thus, this study investigates the contrasting effects of olanzapine and lurasidone on the gut microbiome to explore the hypothesis of 'gut neutrality' for lurasidone exposure. Experimental Approach: Using Sprague–Dawley rats, the effects of olanzapine and lurasidone on the gut microbiome were explored. Faecal and blood samples were collected weekly over a 21‐day period to analyse changes to the gut microbiome and related metabolic markers. Key Results: Lurasidone triggered no significant weight gain or metabolic alterations, instead positively modulating the gut microbiome through increases in mean operational taxonomical units (OTUs) and alpha diversity. This novel finding suggests an underlying mechanism for lurasidone's metabolic inertia. In contrast, olanzapine triggered a statistically significant decrease in mean OTUs, substantial compositional variation and a depletion in short‐chain fatty acid abundance. Microbiome depletion correlated with metabolic dysfunction, producing a 30% increase in weight gain, increased pro‐inflammatory cytokine expression, and increased blood glycaemic and triglyceride levels. Conclusion and Implications: Our results challenge the notion that all antipsychotics disrupt the gut microbiome similarly and highlights the potential benefits of gut‐neutral antipsychotics, such as lurasidone, in managing metabolic side effects. Further research is warranted to validate these findings in humans to guide personalised pharmacological treatment regimens for schizophrenia. [ABSTRACT FROM AUTHOR]

AbstractPsychedelic compounds continue gaining scientific and regulatory traction as potential new treatments for psychiatric disorders. While most psychiatrists will likely not work directly with these compounds, psychedelic research practices provide insights that may improve conventional psychiatric care. Through its emphasis on ‘set and setting’ (mindset and environment, respectively), psychedelic research highlights the importance of non-pharmacologic factors maximizing therapeutic outcomes. While psychedelics and serotonergic antidepressants are distinctly different in their subjective experience, new findings suggest mechanistic overlap between them. Both have been found to modulate neurotrophins, enhance neuroplasticity, and reopen critical periods of learning, molded by the environmental context in which they are administered.This paper will argue that by integrating insights from psychedelic research (particularly set and setting), depression treatment outcomes in traditional psychiatric settings can improve by optimizing non-pharmacological factors in treatment, including the provision of high-quality psychotherapy.

Patients with epilepsy often require long‐term treatment with antiseizure medications, and their impact on daily activities, particularly driving, is of significant concern. The recently published “Guideline for Evaluating Effects of Psychotropic Drugs on the Performance to Drive a Motor Vehicle” in Japan provides a framework that can be referred to for not only the evaluation of new drugs but also the reevaluation of approved drugs. This study conducted a literature review regarding the effects of carbamazepine, valproate, lamotrigine, lacosamide, and levetiracetam, which are frequently prescribed for epilepsy, on driving performance following the guideline's tiered evaluation approach. Analyses of pharmacological, pharmacodynamic, and adverse events suggested that these drugs primarily affect arousal function. Driving studies showed that acute administration of carbamazepine, but not chronic monotherapy with carbamazepine, valproate, lamotrigine, and levetiracetam, significantly impairs driving performance. Epidemiological studies have not identified a definitive association between these drugs and traffic accidents. Initial administration of these five antiseizure medications may affect driving performance, warranting special attention, but the influence appears to diminish with continued use. Nevertheless, while long‐term administration of these five drugs may not have a clinically meaningful effect on driving performance, safe driving is not guaranteed for each individual patient, and appropriate individualized guidance is important in clinical practice.

Background: Medication non-adherence (MNA) presents a significant obstacle that negatively impacts treatment effectiveness in mental health disorders. The objective of this review is to study different types of MNA and interventions designed to enhance medication adherence among individuals with mental health disorders. Methods: We conducted an electronic search on PubMed and Google Scholar using keywords such as adherence, non-adherence, compliance, non-compliance, mental health disorders, psychotropic drugs, major depressive disorder (MDD), schizophrenia, anxiety disorders, and bipolar disorders (BD). From the search results, we selected studies pertinent to the objective of the review. Results: Non-adherence can be categorized into primary nonadherence (not starting medication) and secondary non-adherence (not taking the medication as directed). Generally, we can group the reasons for non-adherence into unintentional and intentional. Unintentional non-adherence (UNA) arises when patients genuinely desire to comply with their prescribed course of therapy but are hindered by factors beyond their control. When addressing UNA, interventions should simplify medication regimens, utilize long-acting injectable (LAIs) medications, offer tools to manage medication and provide follow-up reminders. When a patient deliberately decides not to follow their treatment plan, this is known as intentional non-adherence. To improve intentional non-adherence, the focus should be on patient-centred care and shared decision-making, psychoeducation, effective doctor-patient communication, cognitive-behavioral strategies, and addressing concerns related to the side effects of psychotropic drugs. Conclusion: It is crucial to understand that there is no universal solution to address non-adherence in mental health disorders. Each patient has distinct needs and characteristics, making personalized strategies and interventions of utmost significance. [ABSTRACT FROM AUTHOR]

Background/Objectives: Discussions about the possibility of psychologists prescribing medications have been ongoing for several years. The study aims to ascertain the opinion of the Polish professional community of psychologists on the right of psychologists to prescribe psychotropic drugs. Methods: The study was conducted on online forums (Porozumienie Psychologów) associated with psychologists from all over the world from 15 April 2023 to 30 September 2023. The participants were asked to fill out a Google survey consisting of 26 questions. Results: A total of 677 psychologists participated in the study, including 580 (85.7%) women and 97 (14.3%) men. The majority of the respondents were at the peak of their life activity, between 30 and 50 years of age. A large group of respondents believed that a psychologist should have the right to prescribe psychotropic drugs (46.5%) and declared their participation in activities to promote these rights (52.9%). The vast majority of respondents reported that psychologists authorized to prescribe drugs should complete additional courses as part of the pharmacology specialization (74.8%) and should pass an exam in this field (73.4%) or should complete additional courses in the field of pharmacology (74.8%). Such opinions were much more common in the group with psychological specializations. In this group, more people allowed for such a privilege for those who have completed studies, have documented five years of experience, or have a psychotherapist certificate (p < 0.0001). Conclusions: There may be many societal needs that could be successfully met by psychologists obtaining prescriptive privileges. However, psychologists ought to understand that our obligations need to transcend guild concerns and appropriate qualifications. [ABSTRACT FROM AUTHOR]

Introduction Pharmacoepidemiological data suggest that lithium prescriptions for bipolar disorder are gradually decreasing, with less attention having been paid to other indications. Methods We examined lithium prescriptions between 1994 and 2017 in data provided by the Drug Safety in Psychiatry Program AMSP, including psychiatric hospitals in Germany, Austria and Switzerland. We compared lithium use for different diagnoses before and after 2001 and in three periods (T1: 1994–2001, T2: 2002–2009, and T3: 2010–2017). Results In a total of 158,384 adult inpatients (54% female, mean age 47.4±17.0 years), we observed a statistically significant decrease in lithium prescriptions between 1994–2000 and 2001–2017 in patients with schizophrenia spectrum disorder from 7.7% to 5.1% and in patients with affective disorders from 16.8% to 9.6%. Decreases in use were also observed for diagnostic subgroups: schizoaffective disorder (ICD-10 F25: 27.8% to 17.4%), bipolar disorder (F31: 41.3% to 31%), depressive episode (F32: 8.1% to 3.4%), recurrent depression (F33: 17.9% to 7.5%, all: p<0.001) and emotionally unstable (borderline) personality disorder (6.3% to 3.9%, p=0.01). The results in T1 vs. T2 vs. T3 were for F25: 26.7% vs. 18.2% vs. 16.2%, F32: 7.7% vs. 4.2% vs. 2.7%, F33: 17.2% vs. 8.6% vs. 6.6% and for F31: 40.8% vs. 31.7% vs 30.0%, i. e. there was no further decrease for lithium use in bipolar disorder after 2002. Lithium's main psychotropic co-medications were quetiapine (21.1%), lorazepam (20.6%), and olanzapine (15.2%). Discussion In inpatients, the use of lithium has decreased in patients with bipolar disorder and also with various other psychiatric diagnoses. [ABSTRACT FROM AUTHOR]

Functional neurological disorder (FND) is common among children and adolescents, results in significant impairments in quality of life, and places a substantial burden on healthcare systems. Despite this, there is minimal literature to guide prescribing for this population. The purpose of this article is to provide common sense prescribing recommendations for providers who treat pediatric FND. A narrative review was conducted by searching PubMed using keywords related to FND and pharmacology. The narrative synthesis was guided by the objective of providing evidence for generally accepted practices and highlighting contributions and gaps in the literature. There is a dearth of evidence, and unique challenges exist in prescribing for pediatric patients with FND. Efforts should be made to limit prescribing and to discontinue, or de-prescribe, medications that may contribute to polypharmacy or overmedicalization of functional symptoms. Pediatric patients with FND require a thoughtful, multidisciplinary approach. [ABSTRACT FROM AUTHOR]

Background: The misuse of psychotropic medication has increased during the past decade, especially among adolescents. The aim of our study was to describe the prevalence and patterns of the nonmedical use of benzodiazepines (BDZ) and Z‐hypnotics among school‐aged adolescents through the lens of sex. In addition, we sought to analyze the temporal evolution of the nonmedical use of these drugs during the period 2016–2021. Methods: The temporal evolution of the nonmedical use of these drugs was analyzed based on survey data collected in 2016, 2018 and 2021, which includes the first years of the COVID‐19 pandemic. To assess the possible effect of the COVID‐19 pandemic, the year at survey was conducted was introduced as a categorical variable. We used data from the Spanish State Survey on Drug Use in Secondary Education, which covers drug use among students aged 14–18 years. Using multivariate logistic regression models, we estimated the independent effect of different variables (sociodemographic data, use of other psychoactive substances, risk perception and availability) on the nonmedical use of BDZ and Z‐hypnotics. Results: In total, survey data from 95,700 adolescents were included in our analysis. The nonmedical use of BDZ and Z‐hypnotics increased among adolescents during the study period. The adjusted odds ratio (AOR) from 2016 to 2018 was 1.11 (95% CI 0.94–1.31) and from 2018 to 2021 the AOR was 1.26 (95% CI 1.08–1.46), using 2016 and 2018, respectively, as reference years. The nonmedical use of BDZ and Z‐hypnotics was more likely in adolescent girls than boys (AOR = 2.11). The nonmedical use of prescription opioids (AOR = 3.44), novel psychoactive substances and other illicit psychoactive drugs (AOR = 4.10) were risk factors for the nonmedical use of BDZ and Z‐hypnotics in both sexes. Use of cannabis (AOR = 1.38) was a predictor of nonmedical use in female adolescents only. Conclusions: This study shows that the trend of the nonmedical use of BDZ and Z‐hypnotics among school‐aged adolescents in Spain increased between 2016 and 2021. Among adolescents aged 14 to 18, the probability of nonmedical use of these psychoactive substances was twice as high for female adolescents as for male adolescents. [ABSTRACT FROM AUTHOR]

• HiTOP is a dimensional alternative to traditional diagnostic systems. • The HiTOP approach has the potential to improve outcomes across clinical tasks. • HiTOP is consistent with other transdiagnostic approaches to treatment. • Future work should focus on dissemination and the establishment of clinical utility. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a dimensional framework for psychopathology advanced by a consortium of nosologists. In the HiTOP system, psychopathology is grouped hierarchically from super-spectra, spectra, and subfactors at the upper levels to homogeneous symptom components and maladaptive traits and their constituent symptoms, and maladaptive behaviors at the lower levels. HiTOP has the potential to improve clinical outcomes by planning treatment based on symptom severity rather than heterogeneous diagnoses, targeting treatment across different levels of the hierarchy, and assessing distress and impairment separately from the observed symptom profile. Assessments can be performed according to this framework with the recently developed HiTOP-Self-Report (HiTOP-SR). Examples of how to use HiTOP in clinical practice are provided for the internalizing spectrum, including the use of the Unified Protocol and other modularized treatments, measurement-based care, psychopharmacology, and in traditionally underserved populations. Future directions are discussed in this State of the Science review including HiTOP's use in further developing transdiagnostic treatments, extending the model to include other information such as environmental factors, establishing the treatment utility of clinical assessment for the HiTOP-SR, developing new treatments, and disseminating the model.

Objective: Treatment for anorexia nervosa (AN) remains challenging; there are no approved psychopharmacological interventions and psychotherapeutic strategies have variable efficacy. The investigation of evidence‐based treatments has so far been compounded by an underdeveloped understanding into the neurobiological changes associated with the acute stages of AN. There is converging evidence of deficiencies in neuroplasticity in AN. Method: This paper provides an overview of neuroimaging, neuropsychological, molecular and qualitative findings relating to neuroplasticity in AN, translating these findings to the identification of novel biological and psychotherapeutic strategies. Results: Novel psychopharmacological approaches that may ameliorate deficiencies in neuroplasticity include medications such as ketamine, psilocybin and human recombinant leptin. Anti‐inflammatory medications and brain‐derived neurotrophic factor mimetics may emerge as potential treatments following further research. Psychotherapeutic strategies that may target neuroplastic deficiencies, as well as having wider effects on identity, include imagery rescripting, memory specificity training, cognitive remediation therapy, exposure therapies, narrative therapies, cultural interventions (e.g. music and arts therapies) and yoga/mindfulness‐based interventions. Conclusions: Treatments specifically targeted towards mitigating the neurobiological sequalae of AN are warranted, and emerging neurobiological and neuropsychological research utilising longitudinal designs and large sample sizes, as well as initial feasibility studies, are necessitated to bolster translational efforts. Highlights: There is converging evidence from neuroimaging, neuropsychological, molecular and qualitative research suggestive of altered neuroplasticity during the acute stages of anorexia nervosa (AN), which is also a transdiagnostic feature across psychiatric disorders.Novel pharmacological treatments that are used for the treatment of other conditions in humans, and could be applied to target neuroplasticity in AN, include ketamine, psilocybin, human recombinant leptin and anti‐inflammatory medications.Psychotherapeutic strategies that may target neuroplastic deficiencies in AN, some of which have already been investigated, include those targeting cognitive problems or biases (e.g. imagery rescripting, memory specificity training, cognitive remediation therapy (CRT)), fear (e.g. exposure‐based therapies), stress (e.g. yoga/mindfulness‐based interventions) and identity (e.g. narrative therapies, cultural interventions such as arts and music‐based therapies).

This study aimed to 1) examine how psychopharmacotherapy and mindfulness-based stress reduction (MBSR) influence absenteeism and job performance among individuals with anxiety disorders and 2) compare the effectiveness of these treatments in improving work performance. Adults (N = 67) with a primary anxiety disorder were recruited to participate in the study. Participants were randomized to escitalopram, a common treatment for anxiety disorders, or MBSR. Absenteeism and job performance were measured with the Health and Work Performance (HPQ) questionnaire prior to treatment and at the week 24 follow up. At week 24, individuals in the escitalopram arm and the MBSR arm showed significant improvements in partial days of missed work due to mental/physical health problems from baseline (1.00 [0.00–2.50] to 0.00 [0.00 = 1.00], p =.034 and 0.00 [0.00–2.00] to 0.00 [0.00 = 1.00], p =.001, respectively). In the MBSR arm only, job performance increased from baseline to week 24 (65.00 [50.00–80.00] to 75.00 [67.50–82.50], p =.017). None of the outcome variables significantly varied by group at baseline or week 24. Our study finds evidence that MBSR improves work performance equivalently to SSRI medication among individuals with anxiety disorders. Given the limitations of SSRIs, MBSR should be considered as an alternative to individuals who desire improved anxiety symptoms and work outcomes. ClinicalTrials.gov Identifier: NCT03522844. • Study compares effects of meditation to medication on occupational functioning. • MBSR and escitalopram improve work-related outcomes equivalently. • MBSR is a viable treatment option for anxiety patients with occupational concerns.

Background: Benzodiazepines are frequently prescribed drugs; however, their prolonged use can lead to tolerance, dependence, and other adverse effects. Despite these risks, long-term use remains common, presenting a public health concern. This study aims to explore the beliefs and opinions held by the public regarding benzodiazepines, as understanding these perspectives may provide insights into their usage patterns. Methods: We collected public tweets published in English between January 1, 2019, and October 31, 2020, that mentioned benzodiazepines. The content of each tweet and the characteristics of the users were analyzed using a mixed-method approach, including manual analysis and semi-supervised machine learning. Results: Over half of the Twitter users highlighted the efficacy of benzodiazepines, with minimal discussion of their side effects. The most active participants in these conversations were patients and their families, with health professionals and institutions being notably absent. Additionally, the drugs most frequently mentioned corresponded with those most commonly prescribed by healthcare professionals. Conclusions: Social media platforms offer valuable insights into users' experiences and opinions regarding medications. Notably, the sentiment towards benzodiazepines is predominantly positive, with users viewing them as effective while rarely mentioning side effects. This analysis underscores the need to educate physicians, patients, and their families about the potential risks associated with benzodiazepine use and to promote clinical guidelines that support the proper management of these medications. Clinical trial number: Not applicable. Significant outcomes: • Most Twitter users consider benzodiazepines effective, with only 5% mentioning side effects. • A significant percentage of users reported combining benzodiazepines with other psychopharmacological drugs, or even with alcohol and other addictive substances. • Our results indicate an alarming minimization of the risks associated with benzodiazepine use.

The introduction of the first antipsychotic drug, chlorpromazine, was a milestone for psychiatry. The authors review the history, classification, indications, mechanism, efficacy, side effects, dosing, drug initiation, switching, and other practical issues and questions related to antipsychotics. Classifications such as first-generation/typical versus second-generation/atypical antipsychotics are neither valid nor useful; these agents should be described according to the Neuroscience-based Nomenclature (NbN). Antipsychotic drugs are not specific for treating schizophrenia. They reduce psychosis regardless of the underlying diagnosis, and they go beyond nonspecific sedation. All currently available antipsychotic drugs are dopamine blockers or dopamine partial agonists. In schizophrenia, effect sizes for relapse prevention are larger than for acute treatment. A major unresolved problem is the implausible increase in placebo response in antipsychotic drug trials over the decades. Differences in side effects, which can be objectively measured, such as weight gain, are less equivocal than differences in rating-scale-measured (subjective) efficacy. The criteria for choosing among antipsychotics are mainly pragmatic and include factors such as available formulations, metabolism, half-life, efficacy, and side effects in previous illness episodes. Plasma levels help to detect nonadherence, and once-daily dosing at night (which is possible with many antipsychotics) and long-acting injectable formulations are useful when adherence is a problem. Dose-response curves for both acute treatment and relapse prevention follow a hyperbolic pattern, with maximally efficacious average dosages for schizophrenia of around 5 mg/day risperidone equivalents. Computer apps facilitating the choice between drugs are available. Future drug development should include pharmacogenetics and focus on drugs for specific aspects of psychosis.

Objective: Antipsychotic effectiveness in preventing relapse declines around menopausal age in women with schizophrenia or schizoaffective disorder (SSD). It is not known whether systemic menopausal hormone therapy (MHT) can help to prevent psychosis relapse. Methods: A within-subject study design was used to study the effectiveness of MHT in preventing relapse in a Finnish nationwide cohort of women with SSD between 40 and 62 years of age who used MHT during follow-up (1994–2017). Hazard ratios adjusted for age and psychotropic drug use were calculated for psychosis relapse as main outcome and any psychiatric hospitalization as secondary outcome. Results: The study population comprised 3,488 women using MHT. Use of MHT was associated with a 16% lower relapse risk (adjusted hazard ratio [aHR]=0.84, 95% CI=0.78–0.90) when compared to non-use. Stratified by age, MHT was associated with decreased relapse risks when used between ages 40–49 (aHR=0.86, 95% CI=0.78–0.95) and ages 50–55 (aHR=0.74, 95% CI=0.66–0.83), but not between ages 56–62 (aHR=1.11, 95% CI=0.91–1.37). Similar effectiveness was found for estrogen alone or combined with fixed or sequential progestogens (aHRs between 0.79 and 0.86), transdermal and oral formulations (aHRs 0.75–0.87), and for most specific formulations (aHRs 0.75–0.85), except tibolone (aHR=1.04, 95% CI=0.75–1.44) and formulations with dydrogesterone (aHR=1.05, 95% CI=0.85–1.30). Similar results were observed with any psychiatric hospitalization as outcome measure. Conclusions: The findings underscore the potential value of MHT in preventing psychosis relapse among women with SSD of menopausal age. These findings translate clinical evidence on the neuroprotective effects of estrogens to real-world settings, encompassing a group of women for whom current antipsychotic treatment options may be insufficient.

The potent hallucinogen N,N-dimethyltryptamine (DMT) has garnered significant interest in recent years due to its profound effects on consciousness and its therapeutic psychopotential. DMT is an integral (but not exclusive) psychoactive alkaloid in the Amazonian plant-based brew ayahuasca, in which admixture of several β-carboline monoamine oxidase A (MAO-A) inhibitors potentiate the activity of oral DMT, while possibly contributing in other respects to the complex psychopharmacology of ayahuasca. Irrespective of the route of administration, DMT alters perception, mood, and cognition, presumably through agonism at serotonin (5-HT) 1A/2A/2C receptors in brain, with additional actions at other receptor types possibly contributing to its overall psychoactive effects. Due to rapid first pass metabolism, DMT is nearly inactive orally, but co-administration with β-carbolines or synthetic MAO-A inhibitors (MAOIs) greatly increase its bioavailability and duration of action. The synergistic effects of DMT and MAOIs in ayahuasca or synthetic formulations may promote neuroplasticity, which presumably underlies their promising therapeutic efficacy in clinical trials for neuropsychiatric disorders, including depression, addiction, and post-traumatic stress disorder. Advances in neuroimaging techniques are elucidating the neural correlates of DMT-induced altered states of consciousness, revealing alterations in brain activity, functional connectivity, and network dynamics. In this comprehensive narrative review, we present a synthesis of current knowledge on the pharmacology and neuroscience of DMT, β-carbolines, and ayahuasca, which should inform future research aiming to harness their full therapeutic potential.

The introduction of a new psychopharmaceutical medication instead of the previous one always poses a certain challenge. In the case of antipsychotics (AP), these problems are considerably more complicated and are mainly caused by the question of dose equivalents, but also by the pharmacokinetic properties of the drug. In the case of partial dopamine D2 agonists, an additional issue is the possibility of deterioration when switching from the previous D2 antagonists to these drugs. Cross-titration is therefore generally recommended. Finally, due to the capsule form, it is not possible to increase the dose of cariprazine by less than 1.5 mg during titration. In this paper, we have presented our proposal to replace the most commonly used second-generation APs with the third-generation AP cariprazine. We have taken into account the dose equivalents, the pharmacological forms of the drugs and their pharmacokinetic and pharmacodynamic properties. [ABSTRACT FROM AUTHOR]

The prevalence of obesity is increasing worldwide, resulting in various health issues such as hypertension, dyslipidemia, diabetes mellitus, heart disease, and a lower life expectancy. Importantly, several psychiatric disorders and the use of psychotropic medications have been linked to obesity, and the possible risk factors need further investigation. This study examined the prevalence of obesity and its associated factors using a self‐administered questionnaire. Participants were recruited from three outpatient clinics and individuals who met one or more of the ICD‐10 F0‐F9, G4 diagnoses were included. In total, 1384 participants completed the questionnaire about their lifestyle. Statistical analysis compared the demographic and clinical characteristics of the individuals who were obese (Body Mass Index: BMI ≥25) and those who were non‐obese (BMI <25). The results revealed that the factors associated with obesity in psychiatric outpatients were being male, prolonged treatment duration, eating out frequently, and use of both second‐ and first‐generation antipsychotics. The study emphasized the importance of closely monitoring BMI in individuals with multiple obesity‐related factors. [ABSTRACT FROM AUTHOR]

Sex-related differences in psychopharmacology present unique challenges in both clinical and research settings. Recognition of sex differences in psychopharmacological treatment has increased in recent years, but a significant research gap regarding variations between men and women still exists. Biological factors, including hormonal fluctuations, genetic factors, and brain structure differences, contribute significantly to differential drug responses. Moreover, social determinants can influence the differential burden of psychiatric disorders between the sexes and may impact treatment plans. Incorporating sex as a key variable in personalized treatment programs and plans holds the potential to optimize efficacy and minimize adverse effects in psychopharmacology. Sex-related challenges in psychopharmacology necessitate a nuanced approach to treatment. Further research is needed to fully understand these differences and to develop guidelines for personalized medication management. By addressing these challenges, clinicians can improve treatment outcomes and enhance the quality of life of patients with psychiatric disorders. [ABSTRACT FROM AUTHOR]

Background: Pharmacological resistance in severe recurrent mood and anxiety disorders remains a significant challenge in modern biological psychiatry. This case report investigates the intricate decision-making process employed by physicians when managing patients resistant to conventional pharmacotherapy. Methods: Informed consent was obtained from the patient. Following this, the case report was developed using the CARE checklist (2013) to ensure a comprehensive and systematic documentation of the treatment process and outcomes. Results: The patient's treatment history highlights the complex nature of pharmacological resistance and the impact of minor medication adjustments versus established clinical practices. A crucial aspect of this case was the patient–physician relationship, particularly addressing the patient's past grievances towards physicians, which played a significant role in the treatment process. Despite efforts to improve the physician's confidence and approach, challenges such as lack of continuity and a fragile therapeutic relationship contributed to treatment failure. Conclusions: This case underscores the importance of psychodynamic models in overcoming pharmacologic challenges. A deeper understanding of the patient–physician dynamics and addressing underlying emotional factors can enhance treatment efficacy and patient outcomes, providing valuable lessons for managing complex cases of treatment resistance.

Observational studies suggest a potential correlation between antidepressants and increased lung cancer risks. However, existing studies are limited to small sample sizes, unadjusted covariates especially smoking status, and unclear exposure duration. We performed a large-scale retrospective cohort study to re-examine the association. We analyzed non-smokers and smokers separately to eliminate the confounding effect of smoking status. We found patients with long-term antidepressant use were at a lower risk of lung cancer in both smokers and non-smokers (odds ratio (OR), 0.61; 95% CI: 0.46–0.80, OR: 0.75; 95% CI: 0.65–0.86). None of the antidepressants was associated with an increased lung cancer risk. [ABSTRACT FROM AUTHOR]

For 3000 years, psychedelics have been used in religious contexts to enhance spiritual thinking, well-being, and a sense of community. In the last few years, a renaissance in the use of psychedelic drugs for mental disorders has occurred in Western society; consequently, a pressing scientific need to elucidate the intricate mechanisms underlying their actions has arisen. Psychedelics mainly bind to serotonin (5-HT) receptors, particularly 5-HT2A receptors, but may also bind to other receptors. Unlike conventional psychotropic drugs used in psychiatry, psychedelics introduce a distinctive complexity. They not only engage in receptor activation, but also exert influence over specific neural circuits, thereby facilitating transformative cognitive experiences and fostering what many have identified as a spiritual contemplation or mystical experience. This comprehensive review describes clinical studies that have examined the propensity of psychedelics to enhance spiritual, mystical, and transcendent cognitive states. This multifaceted nature, encompassing diverse components and paradigms, necessitates careful consideration during the investigation of psychedelic mechanisms of action to avoid oversimplification. The present review endeavours to elucidate the mechanisms underlying the actions of 2 principal psychedelic substances, psilocybin and lysergic acid diethylamide (LSD), with a focus on monoamine and glutamate receptor mechanisms; molecular aspects, such as neuroplasticity and epigenetics; as well as the impact of psychedelics on brain circuits, including the default mode network and the cortico–striato–thalamo–cortical network. Given their distinctive and intricate mechanisms of action, psychedelics necessitate a novel conceptual framework in psychiatry, offering insight into the treatment of mental health disorders and facilitating the integration of the realms of brain, mind, and spirituality.

Objective: To describe how the intersectionality of race, ethnicity, and language with autism and intellectual and developmental disability (IDD) impacts mental health inequities in psychopharmacological management of youth. Method: This was a scoping review in which a series of searches were conducted in PubMed, Web of Science, Google Scholar, and manual review of the articles collected. Results: Although autism and/or IDD increases the risk for poor physical and mental health, social determinants of health such as race, ethnicity, and language account for approximately a third of poor outcomes. Minoritized children with autism/IDD experience significantly greater delays to diagnosis and misdiagnosis and are less likely to receive appropriate services. Access to psychological testing and psychosocial services is often limited by availability, skilled practitioners, a shortage of non-English-language providers or interpreters, and poor reimbursement. Conclusion: The intersectionality of autism and/or IDD with race, ethnicity, and language compounds the health inequities associated with either of these challenges independently.

In 1762, Louis-Antoine Marquis de Caraccioli (1719–1803), a prolific writer of the eighteenth century, dedicated a book to a psychological theme that medicine has forgotten: ' gaité ' in French, which we will translate as 'cheerfulness'. At the beginning of the nineteenth century, this work inspired two doctoral theses in medicine, one defended in Montpellier, the other in Paris. In their texts, Louis Monferran (1785–?) and Vincent Rémi Giganon (1794–1857) explored the therapeutic benefits of the medical prescription of cheerfulness. In addition to lifestyle recommendations, they focused on the psychotropic substances available to them: alcohol, coca, hemp and opiates. In an original and novel way, Giganon introduced and recommended ' le gaz oxydule d'azote inspiré ', or inhaled nitrous oxide gas. [ABSTRACT FROM AUTHOR]

Notably, the sentiment towards benzodiazepines is predominantly positive, with users viewing them as effective while rarely mentioning side effects. This analysis underscores the need to educate physicians, patients, and their families about the potential risks associated with benzodiazepine use and to promote clinical guidelines that support the proper management of these medications. Clinical trial number Not applicable.

BackgroundMethamphetamine use disorder (MethUD) disproportionately affects men who have sex exclusively with men or with men and women (collectively MSM/W), compared to men who have sex with women (MSW). This study is the first MethUD medication trial to compare treatment effect for these groups, hypothesizing that extended-release injectable naltrexone 380mg every 3 weeks plus oral extended-release bupropion 450mg daily would be less effective for MSM/W than MSW.MethodsData come from men (N = 246) in a multi-site, double-blind, randomized, placebo-controlled trial with sequential parallel comparison design. In Stage 1 (6-weeks), participants were randomized to active treatment or placebo. In Stage 2 (6-weeks), Stage 1 placebo non-responders were rerandomized. Treatment response was ≥3 methamphetamine-negative urine samples, out of four obtained at the end of Stages 1 and 2. Treatment effect was the active-versus-placebo between-group difference in the weighted average Stages 1 and 2 responses.ResultsMSM/W (n = 151) were more likely than MSW (n = 95) to be Hispanic, college-educated, and living with HIV. Adjusting for demographics, among MSM/W, response rates were 13.95 % (active treatment) and 2.78 % (placebo) in Stage 1; 23.26 % (active treatment) and 4.26 % (placebo) in Stage 2. Among MSW, response rates were 7.69 % (active treatment) and 5.80 % (placebo) in Stage 1; 3.57 % (active treatment) and 0 % (placebo) in Stage 2. Treatment effect was significantly larger for MSM/W (h = 0.1479) than MSW (h = 0.0227) (p = 0.04).ConclusionsFindings suggest efficacy of extended-release naltrexone plus bupropion for MSM/W, a population heavily burdened by MethUD. While a secondary outcome, this intriguing finding merits testing in prospective trials.

Objective: The COVID-19 pandemic has had a profound impact on individuals with mental health (MH) disorders and on the delivery of MH services. Few studies have examined treatment models not requiring substantial changes to the delivery of services during pandemic restrictions, such as collaborative care management (CoCM) programs. Therefore, a longitudinal retrospective cohort analysis was conducted to examine the impact of the COVID-19 pandemic on a psychopharmacological CoCM program. Method: Data were collected on all U.S. Veterans enrolled in a CoCM program at a large VA during the first 10 months of the COVID-19 pandemic and compared to a matched control group one-year prior to that date. Treatment in the program pre-COVID vs. treatment during the pandemic was compared in relation to baseline symptomatology, improvements in MH symptoms, and program adherence. Results: A total of 462 Veterans were referred during the control period, compared to 351 during the same time period during the pandemic. Veterans enrolled during the first four months of each study arm, to allow for a minimum of 6 months of follow up data, had no differences in baseline symptoms of depression or anxiety between groups. Veterans receiving care during the pandemic had higher rates of program completion than pre-pandemic controls. COVID-era Veterans also had higher rates of depression response compared to controls, but no differences were observed between groups on depression remission, anxiety response, or anxiety remission. Conclusions: Psychopharmacological CoCM treatment models can successfully manage depression and anxiety with no observed decrease in the effectiveness of this intervention even during periods of unprecedented disruptions to MH services.

Introduction: A record of 122.6 million people have sought refuge and asylum across the globe in 2024, exacerbated by emergencies in Ukraine, Sudan, Afghanistan and by the Israel–Hamas war. This number is set to rise to over 130 million people in refugee situations in 59 countries this year alone. With refugees suffering from higher rates of mental health difficulties than the general population, there is an urgent need to provide an expedient, socially just, transculturally informed pathway into humanistic psychological care services for these individuals. The objectives of this study were to explore how therapeutic practitioners are working effectively with displaced individuals presenting with embodied trauma, their experiences of transcultural approaches to therapeutic work and the impact of working alongside psychopharmacological medications in this commonly overprescribed client group. Method: A qualitative semi‐structured interview was operationalised with 12 therapeutic practitioners who have worked with displaced individuals, utilising reflexive thematic analysis of the data. Results: Findings highlight a critical need for an updated transculturally informed, humanistic, person‐centred pathway of care for each displaced individual. Discussion: This study offers facilitators and challenges to using a humanistic, transculturally updated assessment, formulation, treatment plan, and routine outcome measures for embodied trauma. It also considers the importance of working with a client's cultural context of origin, language, universally understood emotions, cultural strengths, preferences for therapy and use of a psychopharmacological review within a holistic constellation of care.

Sex-related differences in psychopharmacology present unique challenges in both clinical and research settings. Recognition of sex differences in psychopharmacological treatment has increased in recent years, but a significant research gap regarding variations between men and women still exists. Biological factors, including hormonal fluctuations, genetic factors, and brain structure differences, contribute significantly to differential drug responses. Moreover, social determinants can influence the differential burden of psychiatric disorders between the sexes and may impact treatment plans. Incorporating sex as a key variable in personalized treatment programs and plans holds the potential to optimize efficacy and minimize adverse effects in psychopharmacology. Sex-related challenges in psychopharmacology necessitate a nuanced approach to treatment. Further research is needed to fully understand these differences and to develop guidelines for personalized medication management. By addressing these challenges, clinicians can improve treatment outcomes and enhance the quality of life of patients with psychiatric disorders.

Pathological dissociation, however, continues to occur after the initial threat has passed, in response to reminders or inaccessibility of safety and security. Present across the spectrum of psychiatric diagnoses, recurrent dissociative symptoms are linked to severe trauma exposure, insecure attachment, treatment non-response, and maladaptive coping behaviors such as substance use, suicidality, and self-harm. However, empirical studies testing treatments specific to dissociative processes remain scarce. This narrative review summarizes existing studies and provides theoretical, neurobiological, and evolutionary perspectives on dissociative processes and treatments for pathological dissociation.Methods: A systematic search of five databases (MEDLINE, EMBASE, APA PsycINFO, CINAHL plus, Scopus) was conducted on April 13, 2023. Peer-reviewed clinical studies with adult participants, assessing intervention effects on dissociative symptoms, were included. Results were thematically analyzed and summarized.Results: Sixty-nine studies were identified, mainly focused on posttraumatic stress disorder, trauma-exposed populations, and borderline personality disorder. Psychotherapy was studied in 72.5% of studies; other interventions included medications and neurostimulation. The majority reported positive outcomes, despite the heterogeneous spectrum of interventions. However, treatment of dissociative symptoms was the primary objective in only a minority.&#x00A0Conclusion: Pathological dissociation is a complex phenomenon involving brain and body systems designed for perceiving and responding to severe threats, requiring an individualized approach. A literature is emerging regarding potentially evidence-based treatments to help those impacted by recurrent dissociative symptoms. When contextualized within a neurobiological and evolutionary perspective, these treatments can be understood as facilitating an internal and/or relational sense of safety, resulting in symptom reduction. Further studies are needed to explore effective treatments for dissociative symptoms.Keywords: derealization, depersonalization, posttraumatic stress disorder, psychotherapy, psychopharmacology, transcranial magnetic stimulation

Abstract Background Lisdexamfetamine dimesylate (LDX) has demonstrated safety and efficacy for treatment of Binge Eating Disorder (BED). However, to date, trials have not included participants with co-occurring psychiatric disorders. This study explores how LDX affects eating disorder psychopathology, symptoms of common psychiatric comorbidities of BED (ADHD, depression, anxiety), and psychological quality of life, in people with moderate to severe BED. Methods These are secondary analyses of an open-label LDX trial conducted in 41 adults (18–40 years) over eight-weeks. Participants received LDX titrated to 50 or 70 mg. Clinical assessments and self-report questionnaires were conducted at baseline and 8-week follow-up. Results Eating disorder psychopathology and psychological quality of life improved after 8-weeks of LDX. No significant group-level changes in depression, anxiety or ADHD severity scores were observed. However, the majority within the small subsets with elevated depression and ADHD symptoms experienced reduced depressive and inattentive symptom severity, respectively. Conclusions We provide proof-of-concept evidence that LDX may provide broader psychological benefits to individuals with BED, beyond reducing their BE frequency. Effects of LDX on anxiety should be monitored closely by clinicians. Early indications suggest that LDX may be effectively used in people with BED, with and without co-occurring psychiatric conditions, however tolerability may be lower in highly complex cases.

In the development of drugs that affect the central nervous system (CNS), it is important to determine whether they have dependence potential and if so, to establish an effective dose within a range that does not manifest dependency. Methods for evaluating drug dependence include selfadministration tests using experimental animals while assessment of the minimum effective dose (MED) involves gross behavioral observation. This study aims to examine the relationship between the most frequently self-administered dose (peak self-administered dose, PSAD) and the MED amongst different types of CNS depressants in order to optimize dose range selection for the evaluation of drug reinforcing effects. PSAD was investigated by intravenous self-administration in rhesus monkeys conducted as daily 2 hr-sessions under a fixed ratio 5 schedule with a 1-min time-out after each administration. MED was investigated by gross behavioral observation following cumulative dosing. For opiates, the PSAD was 0.016 mg/kg/infusion for morphine, 0.06 mg/kg/infusion for codeine, 0.25 mg/kg/infusion for butorphanol and 0.063 mg/kg/infusion for pentazocine. For anesthetics and sedatives, the PSAD was 0.5 mg/kg/infusion for pentobarbital, 0.25 mg/kg/infusion for thiopental, 0.06 mg/kg/infusion for ketamine and 0.063 mg/kg/infusion for midazolam. The PSAD/MED ratio was 1/63-1/32 for opiates and 1/8-1/2 for anesthetics and hypnosedatives. While previous research by Fujiwara et al. (2016) suggested that a dose range lower than the MED for gross behavioral effects should be used for intravenous self-administration in the evaluation of drug reinforcing effects, this study further indicates that the optimal dose range may vary depending on drug type.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interaction, verbal and nonverbal communication, and behaviors or interests. Besides behavioral, psychopharmacological and biomedical interventions there is increasing evidence of non-invasive treatments like neurofeedback (NFB) that can improve brain activity. In this study, we have investigated whether NFB can improve cognitive functions in children with ASD. Thirty-five children with ASD (7–17 years) were selected by purposive sampling. The subjects underwent 30 sessions of NFB training for 20 min over 10 weeks' period. Psychometric tests i.e. Childhood Autism Rating Scale (CARS), IQ scoring and Reward sensitivity tests were administered at baseline. Pre and post NFB intervention assessment of executive functions, working memory and processing speed were done by NIH Toolbox Cognition Batteries. Friedman test revealed that children showed a statistically significant improvement in the NIH Tool Box cognitive assessments, including the Flankers Inhibitory Control and Attention Test (Pre-test = 3.63, Post-test = 5.22; p = 0.00), the Dimensional Change Card Sorting Test (Pre-test = 2.88, Post-test = 3.26; p = 0.00), the Pattern Comparison Processing Speed Test (Pre-test = 6.00, Post-test = 11:00; p = 0.00) and the List Sorting Working Memory Test (Pre-test = 4.00, Post-test = 6:00; p = 0.00), and displayed a trend of improvement at 2-month follow-up (Flankers Inhibitory Control and Attention Test (Post-test = 5.11 ± 2.79, Follow-Up = 5.31 ± 2.67; p = 0.21), the Dimensional Change Card Sorting Test (Post-test = 3.32 ± 2.37, Follow-Up = 3.67 ± 2.35; p = 0.054), the Pattern Comparison Processing Speed Test (Post-test = 13.69 ± 9.53, Follow-Up = 14.42 ± 10.23 p = 0.079) and the List Sorting Working Memory Test (Post-test = 6.17 ± 4.41, Follow-Up = 5.94 ± 4.03; p = 0.334). Our findings suggest NFB intervention for 10 weeks produce improvement in executive functions (Inhibitory Control and Attention and Cognitive Flexibility), Processing Speed and Working Memory in ASD Children.

Background: Child and adolescent antidepressant use increased post-pandemic, but it is unknown if this disproportionally affected those who develop post-acute sequelae of coronavirus disease 2019 (COVID) or long COVID. This study compared the risk of antidepressant initiation among children and adolescents with long COVID with those who had COVID but did not have evidence of long COVID. Methods: Our retrospective cohort study of children and adolescents aged 3–17 years at the first evidence of COVID or long COVID from October 1, 2021 through April 4, 2022 was conducted within Komodo's Healthcare Map™ database. The index date was the earliest date of a medical claim associated with a COVID (COVID comparators) or long COVID diagnosis (long COVID cases). The baseline period was six months before the index date. The outcome was antidepressant initiation within twelve months after the index date. Due to the large number of COVID relative to long COVID cases, COVID comparators were randomly selected with a ratio of 2 COVID to 1 long COVID. We used propensity score matching to control for confounding due to imbalances in the baseline covariates. Log-binomial models estimated the relative risk (RR) of antidepressant initiation in the propensity score matched sample. We conducted several sensitivity analyses to test the robustness of our findings to several assumptions. Results: Our child and adolescent sample included 18 274 with COVID and 9137 with long COVID. Compared with those with COVID, a larger proportion of long COVID children and adolescents had psychiatric disorders, psychotropic use, medical comorbidities, were previously hospitalized, or visited the emergency department. In the propensity score-adjusted analysis, the long COVID group had a statistically significant higher risk of antidepressant initiation relative to the COVID comparator (adjusted-RR: 1.40, 95% CI = 1.20, 1.62). Our findings were robust across sensitivity analyses. Conclusions: The increased risk of antidepressant initiation following long COVID warrants further study to better understand the underlying reasons for this higher risk. Emerging evidence of long COVID's impact on child mental health has important implications for prevention and early interventions. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusion The aim of this study was to compare the clinical characteristics of childhood‐onset schizophrenia (COS) and early‐onset schizophrenia (EOS) during the first‐ episode psychosis and the stable period, to examine psychopharmacological treatment approaches, and to investigate potential predictive factors for prognosis.Demographic, clinical, and psychopharmacological therapy data for 31 patients diagnosed with COS and 66 with EOS were retrieved from the file records in this multicenter study. Symptom distribution and disease severity and course were evaluated twice, in the acute psychotic stage and in the latest stable phase, during follow‐up using the positive and negative syndrome scale (PANSS) and clinical global impression (CGI) scales.A statistically significant difference was observed between the groups' CGI improvement rates and median last stable stage PANSS positive, negative, and general psychopathology symptom scores (p = .005, p = .031, p = .005, and p = .012, respectively). Premorbid neurodevelopmental disorder and obsessive‐compulsive disorder and comorbidities were more common in the COS group (p = .025 and p = .030, respectively), and treatment required greater multiple antipsychotic use in that group (p = .013). When the independent variables affecting the difference between pre‐ and post‐treatment PANSS scores were examined using linear regression analysis, the model established was found to be statistically significant (F = 5.393; p = .001), and the group variable (p = .024), initial disease severity (p = .001), and socioeconomic level (p = .022; p = .007) emerged as predictive factors for the disease course.Although early diagnosis and treatment is an important factor in improving prognosis in schizophrenia, more specific predictors for schizophrenia need to be identified. Additionally, preventive programs and pharmacological methods need to be developed in children with neurodevelopmental problems, particularly those from low socioeconomic status families.

Bei der Einstellung von Patient:innen auf ein Psychopharmakon kann nicht sicher vorhergesagt werden, ob sie wirklich eine wirksame Medikamentenkonzentration aufbauen oder nicht. Therapeutisches Drug Monitoring kann im Sinne der personalisierten Medizin dabei helfen, individuelle Eigenschaften der Patient:innen zu berücksichtigen und so die Dosierung der angeordneten Psychopharmaka zu optimieren.

This survey assessed psychiatry residents'/early-career psychiatrists' attitudes towards the utility of therapeutic drug monitoring (TDM) of antipsychotics. A previously developed questionnaire on attitudes on TDM utility during antipsychotic treatment was cross-sectionally disseminated by national coordinators between 01/01/2022–31/12/2023. The frequency of using TDM for antipsychotics other than clozapine was the main outcome in a linear regression analysis, including sex, clinical setting, caseload, and factors generated by an exploratory factor analysis. Comparisons between residents and early-career psychiatrists, respondents working in in- and outpatient settings, and low-/middle- and high–income countries were performed. Altogether, 1,237 respondents completed the survey, with 37.9% having never used TDM for antipsychotics. Seven factors explained 41% of response variance; six of them were associated with frequency of TDM use (p < 0.05). Items with highest loadings for factors included clinical benefits of TDM (factors A and E: 0.7), negative expectations for beliefs of patients towards TDM (factor B: 0.6–0.7), weak TDM scientific evidence (factor C: 0.8), and TDM availability (factor D: −0.8). Respondents from low-/middle-income countries were less likely to frequently/almost always use TDM compared to high-income countries (9.4% vs. 21.5%, p < 0.001). TDM use for antipsychotics was poor and associated with limited knowledge and insufficient availability. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Elective amputation as a treatment for Body Integrity Identity Disorder (BIID) or Body Integrity Dysphoria (BID) where noninvasive treatments prove ineffective and the patient's distress is substantial, may permit long‐term remission of symptoms at follow‐up. We present the one‐year follow‐up post‐surgery of an ambidextrous male who sought elective amputation of his left hand's fourth and fifth fingers after an unsuccessful trial of psychotherapy and pharmacotherapy for Body Integrity Dysphoria. He had no psychiatric comorbidities. At one‐year follow‐up, his dysphoria was still in remission. He exhibited full adaptation in his social and occupational life, demonstrating increased ease in hand use compared to pre‐amputation. He reported sleeping well, happiness, good health and continued acceptance by friends and family. This one‐year post‐surgery follow‐up, at 22 years old, underscores the efficacy of amputation as a curative treatment, high patient satisfaction, and the quality of life gained through the procedure.

Cardiovascular disease is a major global burden and a leading cause of premature death among patients with severe mental illness. Over time, research and clinical practice have paid increased attention to the impact of psychiatric medications on cardiac repolarization. In a resource-limited setting, it is common for psychotropic medications to be initiated and maintained in an outpatient setting without baseline or follow up ECG. This study evaluated the determinants and predictors of QT abnormalities among patient taking psychotropic drugs. We conducted a cross-sectional study in a population of 150 psychiatric patients on psychotropics and 75 controls. We studied the effects of various psychotropic drugs on QT dispersion (QTd) and corrected QT interval (QTc) as well as correlation with the types and dosages of psychotropic drugs used. All the subjects had detailed clinical examination and resting electrocardiogram (ECG) at 25 mm/sec done. QTc was determined using Bazett formula and QTd was determined by subtracting shortest from longest QT in 12-lead ECG. The prevalence of prolonged QTc and QTd as well as the mean QTc and QTd were significantly higher in patients than the control group. The mean QTc was significantly higher in patient on typical antipsychotics compared to those on atypical antipsychotics. Age, heart rate and antipsychotic dose in chlorpromazine equivalent were predictors of QTc with the heart rate being the most powerful predictor among them. Psychotropic drugs use is associated with QTc and QTd prolongation with age, heart rate and antipsychotic dose as predictors of QTc. [ABSTRACT FROM AUTHOR]

Pregabalin is a medication primarily used in the treatment of neuropathic pain and anxiety disorders, owing to its gabapentinoid properties. Pregabalin monotherapy faces limitations due to its variable efficacy and dose-dependent adverse reactions. In this study, we conducted a comprehensive investigation into the potentiation of pregabalin's analgesic effects by dexborneol, a neuroprotective bicyclic monoterpenoid compound. We performed animal experiments where pain models were induced using two methods: peripheral nerve injury, involving axotomy and ligation of the tibial and common peroneal nerves, and incisional pain through a longitudinal incision in the hind paw, while employing a multifaceted methodology that integrates behavioral pharmacology, molecular biology, neuromorphology, and lipidomics to delve into the mechanisms behind this potentiation. Dexborneol was found to enhance pregabalin's efficacy by promoting its transportation to the central nervous system, disrupting self-amplifying vicious cycles via the reduction of HMGB1 and ATP release, and exerting significant anti-oxidative effects through modulation of central lipid metabolism. This combination therapy not only boosted pregabalin's analgesic property but also notably decreased its side effects. Moreover, this therapeutic cocktail exceeded basic pain relief, effectively reducing neuroinflammation and glial cell activation—key factors contributing to persistent and chronic pain. This study paves the way for more tolerable and effective analgesic options, highlighting the potential of dexborneol as an adjuvant to pregabalin therapy. [ABSTRACT FROM AUTHOR]

Social media data provide unprecedented access to discussions of active, naturalistic, and often real-time cannabis use in an era of cannabis policy liberalization. The aim of this study was to explore psychological and environmental correlates of cannabis effects by applying computational social science approaches to a large dataset of unprompted reports of naturalistic cannabis use with corresponding self-reported numerical ratings of subjective highness. Post title text was extracted via the Pushshift dataset from N = 328,865 posts to the r/trees Reddit community, where posters self-assess and disclose how high they feel on a scale from 1 to 10 (M = 6.9, SD = 1.8). Structural topic modelling and Linguistic Inquiry and Word Count (LIWC) dictionary-based approaches were applied to identify (1) frequently discussed topics and (2) text indicative of 5 psychological processes (affective, social, cognitive, perceptual, biological), respectively, as well as to examine relationships between subjective highness and (1) topic prevalence and (2) psychological process word counts. A 40-topic model was selected for interpretation based on semantic coherence and exclusivity. The most discussed topics in a 40-topic model were characterized by references to smoking places, social contexts, positive affect, cognitive states, as well as food and media consumed. In LIWC dictionary analyses, words mentioning affective, social, and cognitive processes were referenced more often than perceptual or body processes. Posters reported greater subjective highness when using language that referred to in-person social environments and lower subjective highness when using language that referred to online social environments and positive affect psychological states. This examination of unprompted online reports of naturalistic cannabis use identified textual content referring to affect and to other people as being associated with perceived effects of cannabis. These affective and social aspects of the cannabis use experience were salient to active posters in this online community and should be integrated into experience sampling methods and behavioral pharmacology research, as well as public health messaging.

Patients with major depression often suffer from excessive interpersonal sensitivity, although it is not typically measured in antidepressant clinical trials. Preliminary evidence suggests selective serotonin reuptake inhibitors have the capacity to reduce interpersonal sensitivity. This was a pooled analysis of data from 1709 patients in three randomized, double-blind, placebo-controlled trials of fluoxetine and paroxetine for acute major depressive disorder. Depressive symptoms were assessed with the Hamilton Depression Rating Scale. A factor from the Symptom Checklist was used to assess interpersonal sensitivity. Our outcome of interest was change from baseline scores at the last assessment (up to 8 or 12 weeks, depending on the trial). Both medications produced significantly greater reductions in interpersonal sensitivity relative to placebo. The effect of medication remained significant after controlling for depression improvement, which explained 18.5% of the variation in interpersonal sensitivity improvement among those treated with active medication. The effect of medication on depressive symptoms, relative to placebo, was not influenced by baseline interpersonal sensitivity. The outcome measured interpersonal sensitivity over the last week, and the results do not necessarily reflect changes in long-standing, trait-like patterns of interpersonal sensitivity. Only two medications were studied. Selective serotonin reuptake inhibitors are effective at treating interpersonal sensitivity in acutely depressed patients. This appears to be a unique drug effect that is not only the result of depression improvement. Future clinical trials might benefit from assessing interpersonal sensitivity more routinely. • Paroxetine and fluoxetine reduced interpersonal sensitivity more than placebo. • This effect could not be fully explained by concurrent depression improvement. • Baseline interpersonal sensitivity did not moderate the depression treatment effect.

Background: Lisdexamfetamine dimesylate (LDX) has demonstrated safety and efficacy for treatment of Binge Eating Disorder (BED). However, to date, trials have not included participants with co-occurring psychiatric disorders. This study explores how LDX affects eating disorder psychopathology, symptoms of common psychiatric comorbidities of BED (ADHD, depression, anxiety), and psychological quality of life, in people with moderate to severe BED. Methods: These are secondary analyses of an open-label LDX trial conducted in 41 adults (18–40 years) over eight-weeks. Participants received LDX titrated to 50 or 70 mg. Clinical assessments and self-report questionnaires were conducted at baseline and 8-week follow-up. Results: Eating disorder psychopathology and psychological quality of life improved after 8-weeks of LDX. No significant group-level changes in depression, anxiety or ADHD severity scores were observed. However, the majority within the small subsets with elevated depression and ADHD symptoms experienced reduced depressive and inattentive symptom severity, respectively. Conclusions: We provide proof-of-concept evidence that LDX may provide broader psychological benefits to individuals with BED, beyond reducing their BE frequency. Effects of LDX on anxiety should be monitored closely by clinicians. Early indications suggest that LDX may be effectively used in people with BED, with and without co-occurring psychiatric conditions, however tolerability may be lower in highly complex cases. Trial registration: Australian and New Zealand Clinical Trials Registry (anzctr.org.au) #ACTRN12618000623291. Plain English summary: Lisdexamfetamine dimesylate (LDX) has been shown to reduce binge eating frequency among those with Binge Eating Disorder (BED). However, little is known about how LDX affects symptoms of common co-occurring conditions (ADHD, depression, anxiety) and mental health more broadly. In this study, 41 people with BED received an 8-week course of LDX and their symptoms were monitored before and after treatment. Overall, people experienced a robust improvement in eating disorder psychopathology and psychological quality of life. For those with higher levels of depression and ADHD, LDX had the additional benefit of improving depressive symptoms and inattentive symptom severity, respectively. The effect of LDX on anxiety symptoms appears to be more complex, with an equal proportion of people experiencing a decrease or an increase in anxiety over the course of treatment. Those who experienced reductions in anxiety during treatment tended to have greater concurrent reductions in binge eating frequency. This study provides preliminary evidence that for people with BED, LDX may be effective at improving co-occurring symptoms of eating disorder psychopathology and psychological well-being, and potentially ADHD and depression symptoms when present at an elevated level. More research is needed among a larger sample to verify these findings. [ABSTRACT FROM AUTHOR]

Introduction/Purpose: There is a well-established association between preexisting depression/anxiety and greater postconcussion symptom burden, but the potential impact of antidepressant medications has not been fully explored. The primary objective of this study was to compare preinjury/baseline and postinjury concussion symptomscores and neurocognitive performance of athletes on antidepressant medications, both with healthy controls and with those with depression/anxiety not on antidepressants. Methods: This is a cross-sectional study using data collected from 49,270 junior and high school athletes from computerized neurocognitive assessments (Immediate Post-Concussion Assessment and Cognitive Test [ImPACT]) administered between 2009 and 2018 held by the Massachusetts Concussion Management Coalition. The main outcome measures were symptom scores and neurocognitive performance measures, all of which were assessed both at baseline and postinjury. Statistical analysis included analysis of variance and Tukey pairwise comparisons for continuous variables and Fisher's exact test for categorical variables. Multivariate regression models were used to adjust for potential confounding variables. Results: Both at baseline and postinjury, athletes with depression/anxiety had mean total symptom scores that were more than double that of healthy controls regardless of antidepressant use. Although there were no significant differences in neurocognitive performance at baseline, depression/anxiety was associated with small but significant decreases in postinjury visual memory and visual motor scores. Conclusions: Both at baseline and after sustaining a concussion, young athletes with depression/anxiety experience significantly greater symptom burden compared with healthy controls regardless of antidepressant use.

As access to an essential part of clozapine research from the former Union of Soviet Socialist Republics (USSR) states is very limited, quality aspects have not gained attention so far, and harmonization with modern research standards remains unclear. We performed a systematic search in PubMed, Embase and scientific indexes from former USSR states for articles published in Russian language till January 2023 (PROSPERO Reg. Number CRD42023386737) and assessed their quality using the modified Strengthening the reporting of observational studies in epidemiology (STROBE)-Checklist. We compared quality aspects for papers published before and after 2000. A total of 60 papers were considered. Conflicts of interests and funding sources were reported in 5 and 3 (8 % and 5 %) studies respectively; ethical approval was warranted in two studies (3 %). Statistical analysis was performed in 57 (95 %) studies, but statistical methods were described in 21 (35 %) studies. When comparing studies before and after 2000, there was a trend towards improvement for several aspects, with the only significant differences being the objectives' specification (43 vs 83 %, p < 0.003) and the reporting of statistical methodology (0.0 vs 46 %, p < 0.001), which were more frequently available in papers after 2000. Clozapine papers in Russian language suffered from severe methodological drawbacks limiting generalizability. Changes regarding standardization, transparency, ethics, and good scientific practice are urgently required. Using reporting checklists and predefining protocols are the first steps towards quality upgrade and accelerate the integration of science from the former USSR states into the world scientific system.

In December 2022, the Ministry of Health, Labour and Welfare (MHLW) of Japan issued and implemented the guideline for evaluating the effects of psychotropic drugs on motor vehicle driving performance. This guideline recommends the use of a tiered approach to assess clinically meaningful driving impairment. It is noted that adverse events cannot be solely explained by pharmacokinetics, as the onset and duration of these events vary. Among these adverse events, those affecting alertness, such as drowsiness caused by psychotropic drugs on driving performance, are more frequently observed during initial treatment stages and dose escalation. Hence, when evaluating the effects of psychotropic drugs on driving performance, it becomes crucial to assess the persistence of clinically meaningful impairment. Therefore, the MHLW guideline, developed by the authors, emphasizes the need to assess the temporal profile of adverse events affecting driving in all clinical trials. Additionally, the guideline states that when conducting driving studies, the timing of multiple dosing should consider not only the pharmacokinetics of the investigational drug but also its tolerance.
