Abstract
This paper provides a summary of the role of nitric oxide (NO) and hormones in the development of chronic stress, anxiety, depression, and post-traumatic stress disorder (PTSD). These mental health conditions are prevalent globally and involve complex molecular interactions. Although there is a significant amount of research and therapeutic options available, the underlying mechanisms of these disorders are still not fully understood. The primary pathophysiologic processes involved in chronic stress, anxiety, depression, and PTSD include dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, the intracellular influence of neuronal nitric oxide synthase (nNOS) on transcription factors, an inflammatory response with the formation of nitrergic oxidative species, and reduced serotonergic transmission in the dorsal raphe nucleus. Despite the extensive literature on this topic, there is a great need for further research to clarify the complexities inherent in these pathways, with the primary aim of improving psychiatric care.

Pharmacol Biochem Behav 2024; 242:173819.

Abstract
This report evaluates the effects of chlordiazepoxide, a benzodiazepine commonly prescribed to manage anxiety-related disorders in adolescent/pediatric populations, on elevated plus maze (EPM) performance in juvenile mice. This approach was taken because chlordiazepoxide produces anxiolytic-like effects in multiple models in adult rodents, however, less is known about the behavioral effects of this benzodiazepine in juveniles. Thus, we administered a single intraperitoneal injection of chlordiazepoxide (0, 5, or 10 mg/kg) to postnatal day 35 male C57BL/6 mice. Thirty minutes later, mice were allowed to explore the EPM for 5-min. We found that chlordiazepoxide-treated mice (5 and 10 mg/kg) spent more time exploring the open arms of the EPM. No differences in velocity (cm/s) or distance traveled (cm) were observed between the groups. These results indicate that chlordiazepoxide induces anxiolytic-related behavior in adolescent male mice.

Prog Neuropsychopharmacol Biol Psychiatry 2024; 134:111080. [PMID: 38950840 DOI: 10.1016/j.pnpbp.2024.111080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 06/27/2024] [Accepted: 06/28/2024] [Indexed: 07/03/2024]
Abstract
Growing evidence supports dopamine's role in aversive states, yet systematic reviews focusing on dopamine receptors in defensive behaviors are lacking. This study presents a systematic review of the literature examining the influence of drugs acting on dopamine D2-like receptors on unconditioned and conditioned fear in rodents. The review reveals a predominant use of adult male rats in the studies, with limited inclusion of female rodents. Commonly employed tests include the elevated plus maze and auditory-cued fear conditioning. The findings indicate that systemic administration of D2-like drugs has a notable impact on both innate and learned aversive states. Generally, antagonists tend to increase unconditioned fear, while agonists decrease it. Moreover, both agonists and antagonists typically reduce conditioned fear. These effects are attributed to the involvement of distinct neural circuits in these states. The observed increase in unconditioned fear induced by D2-like antagonists aligns with dopamine's role in suppressing midbrain-mediated responses. Conversely, the reduction in conditioned fear is likely a result of blocking dopamine activity in the mesolimbic pathway. The study highlights the need for future research to delve into sex differences, explore alternative testing paradigms, and identify specific neural substrates. Such investigations have the potential to advance our understanding of the neurobiology of aversive states and enhance the therapeutic application of dopaminergic agents.

J Affect Disord 2024; 358:163-174. [PMID: 38718944 DOI: 10.1016/j.jad.2024.05.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 05/03/2024] [Accepted: 05/04/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND Individuals with prenatal alcohol exposure (PAE) commonly experience co-occurring diagnoses, which are often overlooked and misdiagnosed and have detrimental impacts on accessing appropriate services. The prevalence of these co-occurring diagnoses varies widely in the existing literature and has not been examined in PAE without an FASD diagnosis. METHOD A search was conducted in five databases and the reference sections of three review papers, finding a total of 2180 studies. 57 studies were included in the final analysis with a cumulative sample size of 29,644. Bayesian modeling was used to determine aggregate prevalence rates of co-occurring disorders and analyze potential moderators. RESULTS 82 % of people with PAE had a co-occurring diagnosis. All disorders had a higher prevalence in individuals with PAE than the general population with attention deficit hyperactivity disorder, learning disorder, and intellectual disability (ID) being the most prevalent. Age, diagnostic status, and sex moderated the prevalence of multiple disorders. LIMITATIONS While prevalence of disorders is crucial information, it does not provide a direct representation of daily functioning and available supports. Results should be interpreted in collaboration with more individualized research to provide the most comprehensive representation of the experience of individuals with PAE. CONCLUSIONS Co-occurring diagnoses are extremely prevalent in people with PAE, with older individuals, females, and those diagnosed with FASD being most at risk for having a co-occurring disorder. These findings provide a more rigorous examination of the challenges faced by individuals with PAE than has existed in the literature, providing clinicians with information to ensure early identification and effective treatment of concerns to prevent lifelong challenges.

Abstract
Some mental health problems such as depression and anxiety are more common in females, while others such as autism and attention deficit/hyperactivity (AD/H) are more common in males. However, the neurobiological origins of these sex differences are poorly understood. Animal studies have shown substantial sex differences in neuronal and glial cell structure, while human brain imaging studies have shown only small differences, which largely reflect overall body and brain size. Advanced diffusion MRI techniques can be used to examine intracellular, extracellular, and free water signal contributions and provide unique insights into microscopic cellular structure. However, the extent to which sex differences exist in these metrics of subcortical gray matter structures implicated in psychiatric disorders is not known. Here, we show large sex-related differences in microstructure in subcortical regions, including the hippocampus, thalamus, and nucleus accumbens in a large sample of young adults. Unlike conventional T1-weighted structural imaging, large sex differences remained after adjustment for age and brain volume. Further, diffusion metrics in the thalamus and amygdala were associated with depression, anxiety, AD/H, and antisocial personality problems. Diffusion MRI may provide mechanistic insights into the origin of sex differences in behavior and mental health over the life course and help to bridge the gap between findings from experimental, epidemiological, and clinical mental health research.

Abstract
BACKGROUND Mental health during armed conflicts is of paramount importance, as such situations often lead to increased risks of anxiety and depression symptoms among civilians. The military conflict between the Sudanese army and Rapid Support Forces, which began on April 15, 2023, is currently ongoing mainly in Khartoum State. Despite the significant impact of the conflict on the region, there is a lack of data regarding the mental health status of the residents. The aim of this study is to assess anxiety and depression symptoms among residents of Khartoum State during the first months of the 2023 military conflict. METHOD We conducted a cross-sectional study among residents of Khartoum State between May 27 and June 19 using an online questionnaire. We used standardized screening questionnaires, namely the Generalized Anxiety Disorder (GAD-7) for anxiety and the Patient Health Questionnaire (PHQ-9) for depression. Multiple logistic regression was used to identify sociodemographic factors that are associated with anxiety and depression symptoms. RESULTS Out of the 393 participants in the study, 70% had symptoms suggestive of depression and 57.3% suffered from anxiety symptoms. Both anxiety and depression were associated with being female (p < 0.001). Being married was a predictor of anxiety (p = 0.028) but not depression (p = 0.3). Other predictors were not significant (p > 0.05). CONCLUSION High levels of anxiety and depression symptoms were prevalent among Khartoum residents during the conflict, with females and married individuals at higher risk. Immediate medical assessment is essential for identifying cases and providing support. Mental health services should be integrated into emergency response efforts, particularly focusing on vulnerable groups. Future research should address study limitations and explore coping strategies for anxiety and depression in Sudanese adults.

Abstract
PURPOSE We examined the correlates of disability among people with non-communicable diseases (NCDs) and comorbid common mental disorders (CMDs) from rural India. METHODS The sample comprised 2,486 participants enrolled in a cluster randomized trial (cRCT), Healthier OPtions through Empowerment (HOPE). Participants were 30 years or older, with a diagnosis of major depressive disorder, dysthymia, generalized anxiety disorder, and/or panic disorder on the MINI-International Neuropsychiatric Interview, with hypertension, diabetes, dsylipidemia and/ or ischemic heart disease. Disability was measured with the 12-item version of WHODAS 2.0. The severity of depression and anxiety was measured using the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Scale (GAD-7), respectively. Multiple linear regression analyses were used to examine associations. RESULTS The mean age was 59 ± 10.0 years, three quarters (1864) of the participants were female, and 64.0% were married. More than half of the participants had no formal education (57.9%). Most of the participants had two or more chronic medical conditions (73.0%). The mean disability score was 24.3. The mean depression score was 8.5, and the mean anxiety score was 6.7. Higher levels of disability were reported by participants ≥ 60 years of age, those with moderate and severe depression, and moderate anxiety. Among female participants, being unmarried was associated with greater disability. Male participants without formal education reported greater levels of disability. CONCLUSION Higher severity of CMDs is significantly associated with higher levels of disability. For women, being unmarried and for men having no formal education was associated with higher levels of disability.

Abstract
Sex differences in the effect of prolonged sitting time on anxiety symptoms have not yet been explored. This study examined the sex-specific association between prolonged sitting time and anxiety prevalence in Korean adults. Community-dwelling adults aged >18 years who underwent a cross-sectional structured study survey of physical activity and mental health tests were enrolled as part of the Kangbuk Samsung Hospital Cohort Study from 2012 to 2019. The prevalence of anxiety was evaluated using the Clinically Useful Anxiety Outcome Scale (CUXOS) questionnaire. The mean daily sitting time was 7.9 ± 3.4 h in men and 6.8 ± 3.6 h in women. After adjustments for possible confounding factors, the adjusted mean CUXOS score was the highest in participants sitting for ≥10 h, followed by 5-9 h, and <5 h, in that order. In the post-hoc Bonferroni analysis, there were significant differences in the adjusted mean CUXOS scores in group comparisons. A multivariate logistic regression analysis was conducted after adjusting for potential confounding factors. A prolonged sitting time was positively associated with an increased prevalence of anxiety in both men and women, with stronger associations in women than in men. It is necessary to prevent anxiety by adjusting or reducing sitting time in adults, especially women.

Abstract
The Multifactorial Memory Questionnaire (MMQ; Troyer & Rich, [2002]. Psychometric properties of a new metamemory questionnaire for older adults. The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 57(1), P19-P27) is a widely used measure of subjective memory consisting of three scales: Satisfaction, Ability, and Strategies. Although subjective memory complaints are prevalent across different age groups, the factor structure and psychometric properties of the MMQ have yet to be examined in young adults. Here, we independently replicated the original MMQ factor structure in N = 408 young adults (YA) recruited from undergraduate courses and N = 327 older adults (OA) and, for the first time, assessed the age-invariance of the scale using measurement invariance testing. YAs made significantly higher ratings than OAs on MMQ-Satisfaction and MMQ-Strategies, indicating greater satisfaction with their memory and greater use of strategies, but the groups were similar on MMQ-Ability. The original MMQ factor structure was replicated in OAs but not in YAs, and age invariance was not supported. Future studies seeking to compare young and older adults could therefore consider either requesting modification of the MMQ for use with young adults or using a different scale.

Abstract
The human brain stands as an intricate organ, embodying a nexus of structure, function, development, and diversity. This review delves into the multifaceted landscape of the brain, spanning its anatomical intricacies, diverse functional capacities, dynamic developmental trajectories, and inherent variability across individuals. The dynamic process of brain development, from early embryonic stages to adulthood, highlights the nuanced changes that occur throughout the lifespan. The brain, a remarkably complex organ, is composed of various anatomical regions, each contributing uniquely to its overall functionality. Through an exploration of neuroanatomy, neurophysiology, and electrophysiology, this review elucidates how different brain structures interact to support a wide array of cognitive processes, sensory perception, motor control, and emotional regulation. Moreover, it addresses the impact of age, sex, and ethnic background on brain structure and function, and gender differences profoundly influence the onset, progression, and manifestation of brain disorders shaped by genetic, hormonal, environmental, and social factors. Delving into the complexities of the human brain, it investigates how variations in anatomical configuration correspond to diverse functional capacities across individuals. Furthermore, it examines the impact of neurodegenerative diseases on the structural and functional integrity of the brain. Specifically, our article explores the pathological processes underlying neurodegenerative diseases, such as Alzheimer's, Parkinson's, and Huntington's diseases, shedding light on the structural alterations and functional impairments that accompany these conditions. We will also explore the current research trends in neurodegenerative diseases and identify the existing gaps in the literature. Overall, this article deepens our understanding of the fundamental principles governing brain structure and function and paves the way for a deeper understanding of individual differences and tailored approaches in neuroscience and clinical practice-additionally, a comprehensive understanding of structural and functional changes that manifest in neurodegenerative diseases.

Abstract
Genetics research has potential to alleviate the burden of mental disorders in low- and middle-income-countries through identification of new mechanistic pathways which can lead to efficacious drugs or new drug targets. However, there is currently limited genetics data from Africa. The Uganda Genome Resource provides opportunity for psychiatric genetics research among underrepresented people from Africa. We aimed at determining the prevalence and correlates of major depressive disorder (MDD), suicidality, post-traumatic stress disorder (PTSD), alcohol abuse, generalised anxiety disorder (GAD) and probable attention-deficit hyperactivity disorder (ADHD) among participants of the Uganda Genome Resource. Standardised tools assessed for each mental disorder. Prevalence of each disorder was calculated with 95% confidence intervals. Multivariate logistic regression models evaluated the association between each mental disorder and associated demographic and clinical factors. Among 985 participants, prevalence of the disorders were: current MDD 19.3%, life-time MDD 23.3%, suicidality 10.6%, PTSD 3.1%, alcohol abuse 5.7%, GAD 12.9% and probable ADHD 9.2%. This is the first study to determine the prevalence of probable ADHD among adult Ugandans from a general population. We found significant association between sex and alcohol abuse (adjusted odds ratio [AOR] = 0.26 [0.14,0.45], p < 0.001) and GAD (AOR = 1.78 [1.09,2.49], p = 0.019) respectively. We also found significant association between body mass index and suicidality (AOR = 0.85 [0.73,0.99], p = 0.041), alcohol abuse (AOR = 0.86 [0.78,0.94], p = 0.003) and GAD (AOR = 0.93 [0.87,0.98], p = 0.008) respectively. We also found a significant association between high blood pressure and life-time MDD (AOR = 2.87 [1.08,7.66], p = 0.035) and probable ADHD (AOR = 1.99 [1.00,3.97], p = 0.050) respectively. We also found a statistically significant association between tobacco smoking and alcohol abuse (AOR = 3.2 [1.56,6.67], p = 0.002). We also found ever been married to be a risk factor for probable ADHD (AOR = 2.12 [0.88,5.14], p = 0.049). The Uganda Genome Resource presents opportunity for psychiatric genetics research among underrepresented people from Africa.

Neurosci Biobehav Rev 2024; 164:105789.

Abstract
Anxiety fluctuates across the human menstrual cycle, with symptoms worsening during phases of declining or low ovarian hormones. Similar findings have been observed across the rodent estrous cycle, however, the magnitude and robustness of these effects have not been meta-analytically quantified. We conducted a systematic review and meta-analysis of estrous cycle effects on anxiety-like behaviour (124 articles; k = 259 effect sizes). In both rats and mice, anxiety-like behaviour was higher during metestrus/diestrus (lower ovarian hormones) than proestrus (higher ovarian hormones) (g = 0.44 in rats, g = 0.43 in mice). There was large heterogeneity in the data, which was partially accounted for by strain, experimental task, and reproductive status. Nonetheless, the effect of estrous cycle on anxiety-like behaviour was highly robust, with the fail-safe N test revealing the effect would remain significant even if 21,388 additional studies yielded null results. These results suggest that estrous cycle should be accounted for in studies of anxiety in females. Doing so will facilitate knowledge about menstrual-cycle regulation of anxiety disorders in humans.

The effects of brain serotonin deficiency on the behavioral and neurogenesis-promoting effects of voluntary exercise in tryptophan hydroxylase 2 (R439H) knock-in mice. Neuropharmacology 2024; 258:110082.

Abstract
Exercise is known to reduce depression and anxiety symptoms. Although the cellular and molecular mechanisms underlying this effect remain unknown, exercise-induced increases in neurotransmitter release and hippocampal neurogenesis have been hypothesized to play key roles. One neurotransmitter that has been implicated in both antidepressant-like effects and the regulation of hippocampal neurogenesis is serotonin (5-HT). Complete loss of function of the brain 5-HT synthesis enzyme (tryptophan hydroxylase 2, Tph2) has been reported to prevent exercise-induced increases in neurogenesis and to block a subset of antidepressant-like responses to selective serotonin reuptake inhibitors (SSRIs), but whether partial loss of Tph2 function blocks the behavioral and neurogenic effects of exercise has not been established. This study used four tests that are predictive of antidepressant efficacy to determine the impact of 5-HT deficiency on responses to exercise in male and female mice. Our results demonstrate that low 5-HT impairs the behavioral effects of exercise in females in the forced swim and novelty-suppressed feeding tests. However, genetic reductions in 5-HT synthesis did not significantly impact exercise-induced alterations in cellular proliferation or immature neuron production in the hippocampus in either sex. These findings highlight the importance of brain 5-HT in mediating behavioral responses to exercise and suggest that individual differences in brain 5-HT synthesis could influence sensitivity to the mental health benefits of exercise. Furthermore, the observed disconnect between neurogenic and behavioral responses to exercise suggests that increased neurogenesis is unlikely to be the primary driver of the behavioral effects of exercise observed here.

Abstract
Previous studies showed that glucose has beneficial effects on memory function and can enhance contextual fear learning. To derive potential therapeutic interventions, further research is needed regarding the effects of glucose on fear extinction. In two experimental studies with healthy participants (Study 1: N = 68, 39 females; Study 2: N = 89, 67 females), we investigated the effects of glucose on fear extinction learning and its consolidation. Participants completed a differential fear conditioning paradigm consisting of acquisition, extinction, and return of fear tests: reinstatement, and extinction recall. US-expectancy ratings, skin conductance response (SCR), and fear potentiated startle (FPS) were collected. Participants were pseudorandomized and double-blinded to one of two groups: They received either a drink containing glucose or saccharine 20 min before (Study 1) or immediately after extinction (Study 2). The glucose group showed a significantly stronger decrease in differential FPS during extinction (Study 1) and extinction recall (Study 2). Additionally, the glucose group showed a significantly lower contextual anxiety at test of reinstatement (Study 2). Our findings provide first evidence that glucose supports the process of fear extinction, and in particular the consolidation of fear extinction memory, and thus has potential as a beneficial adjuvant to extinction-based treatments. Registered through the German Clinical Trials Registry (https://www.bfarm.de/EN/BfArM/Tasks/German-Clinical-Trials-Register/_node.html; Study 1: DRKS00010550; Study 2: DRKS00018933).

Spectrum of psychiatric adverse reactions to cyclin-dependent kinases 4/6 inhibitors: A pharmacovigilance analysis of the FDA adverse event reporting system. CNS Neurosci Ther 2024; 30:e14862. [PMID: 39009505 PMCID: PMC11250168 DOI: 10.1111/cns.14862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 06/19/2024] [Accepted: 06/24/2024] [Indexed: 07/17/2024] Open
Abstract
BACKGROUND The emergence of cyclin-dependent kinases 4/6 inhibitors (CDK4/6i) represented a major breakthrough in the treatment of breast cancer over the past decade. In both clinical trials and real-world settings, it was observed that patients using CDK4/6i might experience psychiatric adverse events (PAEs). Herein, we conducted a pharmacovigilance study to comprehensively assess the correlation between CDK4/6i and PAEs. METHOD We obtained individual case safety reports submitted to the FDA Adverse Events Reporting System (FAERS) during the period from January 2015 to December 2023. In disproportionality analysis, the reporting odds ratio (ROR) and information component (IC) values were calculated for each adverse event-drug combination. Univariate logistic regression analysis was utilized to explore factors associated with PAEs following CDK4/6i treatment. RESULTS A total of 95,591 reports related to CDK4/6i were identified, with 6.72% reporting PAEs, and this proportion exhibited an annual upward trend. Based on the ROR and IC values, 17 categories of PAEs were defined as CDK4/6i-related PAEs. Among these PAEs, insomnia, stress, eating disorder, depressed mood, and sleep disorder were very common, each accounting for over 10% of CDK4/6i reports. Ribociclib showed the highest risk signal of CDK4/6i-related PAEs (ROR = 1.89[1.75-2.04], IC025 = 0.79), followed by palbociclib (ROR = 1.47[1.41-1.53], IC025 = 0.49), while abemaciclib did not exhibit a significant signal (ROR = 0.52[0.44-0.62], IC025 = -1.13). Female sex, younger age and weight exceeding 80 kg were significant risk factors for the incidence of CDK4/6i-related PAEs. CONCLUSIONS Using data from a real-world, large-scale spontaneous reporting system for adverse drug reactions, our study delineated the spectrum of PAEs to CDK4/6i. This potentially offered valuable insights for healthcare professionals to manage the risk of PAEs in patients receiving CDK4/6i treatment, particularly those with psychiatric disorders.

Abstract
OBJECTIVES To evaluate associations between self-rated health (SRH) and care outcomes among United States adults with diagnosed HIV infection. DESIGN We analyzed interview and medical record data collected during June 2020-May 2021 from the Medical Monitoring Project, a complex, nationally representative sample of 3692 people with HIV (PWH). Respondents reported SRH on a 5-point Likert type scale (poor to excellent), which we dichotomized into "good or better" and "poor or fair". We computed weighted percentages with 95% confidence intervals (CIs) and age-adjusted prevalence ratios (aPRs) to investigate associations between SRH and HIV outcomes and demographic, psychosocial, and behavioral characteristics. RESULTS Nationally, 72% of PWH reported "good or better" SRH. PWH with the following characteristics had a lower prevalence of "good or better" SRH, compared with those without: any missed HIV care appointment in the last 12 months (aPR 0.86, 95% CI: 0.81-0.91), symptoms of moderate or severe depression (aPR 0.51, 95% CI: 0.43-0.59) and anxiety (aPR 0.60, 95% CI: 0.54-0.68), unstable housing or homelessness (aPR 0.77, 95% CI: 0.71-0.82), and hunger or food insecurity (aPR 0.74, 95% CI: 0.69-0.80), as well as having a mean CD4 count <200 cells/mm 3 vs. CD4 + >500 cells/mm 3 (aPR 0.70, 95% CI: 0.57-0.86). CONCLUSIONS Though SRH is a holistic measure reflective of HIV outcomes, integrated approaches addressing needs beyond physical health are necessary to improve SRH among PWH in the United States. Modifiable factors like mental health, unstable housing or homelessness, and food insecurity warrant further study as potential high-yield targets for clinical and policy interventions to improve SRH among PWH.

Unpredictable Mixed-Valence Outcomes Induce a Chronic and Reversible Generalized Anxiety-like Phenotype in Male Mice. BIOLOGICAL PSYCHIATRY GLOBAL OPEN SCIENCE 2024; 4:100318.

Abstract
Background Clinical anxiety is a generalized state characterized by feelings of apprehensive expectation and is distinct from momentary responses such as fear or stress. In contrast, most laboratory tests of anxiety focus on acute responses to momentary stressors. Methods Apprehensive expectation was induced by subjecting mice (for 18 days) to manipulations in which a running response (experiment 1) or a conditioned stimulus (experiment 2) were unpredictably paired with reward (food) or punishment (footshock). Before this treatment, the mice were tested in an open field and light/dark box to assess momentary responses that are asserted to reflect state anxiety. After treatment, the mice were assessed for state anxiety in an elevated plus maze, social interaction test, startle response test, intrusive object burying test, and stress-induced corticosterone elevations. In experiment 3, we treated mice similarly to experiment 1, but after mixed-valence training, some mice received either no additional training, additional mixed-valence training, or were shifted to consistent (predictable) reinforcement with food. Results We consistently observed an increase in anxiety-like behaviors after the experience with mixed-valence unpredictable reinforcement. This generalized anxiety persisted for at least 4 weeks after the mixed-valence training and could be reversed if the mixed-valence training was followed by predictable reinforcement with food. Conclusions Results indicate that experience with unpredictable reward/punishment can induce a chronic state analogous to generalized anxiety that can be mitigated by exposure to stable, predictable conditions. This learned apprehension protocol provides a conceptually valid model for the study of the etiology and treatment of anxiety in laboratory animals.

Abstract
OBJECTIVE This study examined whether college students with and without depression or anxiety differed in subjective cognitive concerns, academic self-efficacy, and cognitive strategy use. PARTICIPANTS Participants included 582 college students (M = 19.0 ± 1.0 years-old, 79.4% women, 81.9% White). METHODS Participants completed online self-report questionnaires on subjective cognitive functioning, academic self-efficacy, cognitive strategy use, and depression and anxiety symptoms, which were used to categorize participants as having anxiety or depression based on established clinical cutoffs. RESULTS Participants with anxiety or depression reported greater subjective cognitive concerns and lower academic self-efficacy compared to participants without anxiety or depression, but these groups differed only modestly in cognitive strategy use. CONCLUSIONS Despite greater cognitive concerns, participants with anxiety or depression reported only modestly greater cognitive strategy use. Future research should evaluate interventions to increase strategy use among college students with anxiety or depression, tailoring these interventions for modern students by incorporating telehealth approaches and smartphone use.

Abstract
The aim of this study was to assess age- and sex-related differences in multiple sleep latency test (MSLT) results and in the performance of the Epworth Sleepiness Scale (ESS) at classifying objective hypersomnia (mean sleep latency (MSL) ≤ 8 min). We studied 480 consecutive adults (39.3 ± 15.3 years old [18-93], 67.7% female) who underwent hypersomnia evaluation. We fit linear regression models to investigate associations between age and sex and sleep latencies (mean and for every nap), after adjusting for total sleep time and sleep efficiency (on polysomnography), and REM-suppressing antidepressant effect. A logistic regression was performed to assess whether age and sex were associated with sleep-onset REM period (SOREMP) occurrence. ROC analysis assessed the diagnostic performance of ESS scores to identify a MSL ≤ 8 min in different age/sex groups. For every 10 years of age, there was 0.41 (95% CI 0.11-0.72, p = 0.008) min reduction in MSL. Objectively (MSL ≤ 8 min) sleepy patients had shortening of latencies in naps 4 and 5 with aging. Female sex was associated with a higher MSL only in patients with MSL > 8 min. A 2.4% reduction in the odds of SOREMP occurrence was observed for every year of age in objectively sleepy patients (p = 0.045). ESS scores had a better diagnostic performance in older (≥ 50 years old) men than younger (< 50 years old) women (p < 0.05). Older patients with objectively confirmed hypersomnia may be sleepier in later naps, possibly due to less restorative naps and/or circadian rhythm factors. Self-reported sleepiness is more predictive of objective sleepiness in older men than younger women.

Abstract
Research suggests that estradiol may moderate fear extinction. It is unclear whether these results generalize to exposure therapy. The aim of the current study was to determine whether estradiol moderates outcomes in exposure therapy among women with anxiety disorders. Participants were 35 women with a primary diagnosis of an anxiety disorder who participated in the study as part of routine care at an anxiety specialty clinic. Endogenous estradiol was assessed via saliva. They provided subjective distress ratings before (pre) and after (post) an exposure session, as well as after a brief delay (recall). Contrary to predictions, there were no significant differences in exposure outcomes between the high and low estradiol groups. However, among participants with primary obsessive-compulsive disorder (OCD), results were partially consistent with the hypotheses. Women with lower estradiol initially demonstrated more improvement in subjective distress from pre- to post-exposure, but after the delay, significantly greater distress (attenuated extinction recall). Results suggest that women with lower estradiol may respond less favorably to exposure therapy for OCD relative to women with higher estradiol. These findings await replication in larger samples with longer recall delays. Should replication occur, these results may inform the use of estradiol to augment exposure therapy.

Abstract
The aim of this study is to investigate the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) treatment in adolescents with panic disorder (PD). This follow-up study consists of 30 adolescents with PD without agoraphobia, aged 14-17 (15.53 ± .97). They were evaluated with Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children Present, also the Panic and Agoraphobia Scale (PAS) and Beck Anxiety Inventory (BAI) were administered at baseline, at the end of the 4th and 12th weeks of treatment. EMDR therapy which is an eight-phase treatment approach composed of standardized protocols and procedures was applied for 12 weeks, one session per week. The baseline mean of the total PAS score decreased from 40.06 to 13.13 at fourth week and 1.2 at the end of 12th week of treatment. In addition, BAI score decreased significantly from 33.67 to 13.83 at 4 weeks and 5.31 at the end of 12th week of treatment. Overall, our results underscore the effectiveness of EMDR in adolescents with PD. Moreover, the current study suggests that EMDR may represent an effective intervention technique for PD in adolescents to protect against relapses and to overcome a fear of future attacks.

Abstract
Chronic stress is a significant risk factor for the development and recurrence of anxiety disorders. Chronic stress impacts the immune system, causing microglial functional alterations in the medial prefrontal cortex (mPFC), a brain region involved in the pathogenesis of anxiety. High mobility group box 1 protein (HMGB1) is an established modulator of neuronal firing and a potent pro-inflammatory stimulus released from neuronal and non-neuronal cells following stress. HMGB1, in the context of stress, acts as a danger-associated molecular pattern (DAMP), instigating robust proinflammatory responses throughout the brain, so much so that localized drug delivery of HMGB1 alters behavior in the absence of any other forms of stress, i.e., social isolation, or behavioral stress models. Few studies have investigated the molecular mechanisms that underlie HMGB1-associated behavioral effects in a cell-specific manner. The aim of this study is to investigate cellular and molecular mechanisms underlying HMGB1-induced behavioral dysfunction with regard to cell-type specificity and potential sex differences. Here, we report that both male and female mice exhibited anxiety-like behavior following increased HMGB1 in the mPFC as well as changes in microglial morphology. Interestingly, our results demonstrate that HMGB1-induced anxiety may be mediated by distinct microglial MyD88-dependent mechanisms in females compared to males. This study supports the hypothesis that MyD88 signaling in microglia may be a crucial mediator of the stress response in adult female mice.

Abstract
Microglia modulate synaptic refinement in the central nervous system (CNS). We have previously shown that a mouse model with innate high anxiety-related behavior (HAB) displays higher CD68+ microglia density in the key regions of anxiety circuits compared to mice with normal anxiety-related behavior (NAB) in males, and that minocycline treatment attenuated the enhanced anxiety of HAB male. Given that a higher prevalence of anxiety is widely reported in females compared to males, little is known concerning sex differences at the cellular level. Herein, we address this by analyzing microglia heterogeneity and function in the HAB and NAB brains of both sexes. Single-cell RNA sequencing revealed ten distinct microglia clusters varied by their frequency and gene expression profile. We report striking sex differences, especially in the major microglia clusters of HABs, indicating a higher expression of genes associated with phagocytosis and synaptic engulfment in the female compared to the male. On a functional level, we show that female HAB microglia engulfed a greater amount of hippocampal vGLUT1+ excitatory synapses compared to the male. We moreover show that female HAB microglia engulfed more synaptosomes compared to the male HAB in vitro. Due to previously reported effects of minocycline on microglia, we finally administered oral minocycline to HABs of both sexes and showed a significant reduction in the engulfment of synapses by female HAB microglia. In parallel to our microglia-specific findings, we further showed an anxiolytic effect of minocycline on female HABs, which is complementary to our previous findings in the male HABs. Our study, therefore, identifies the altered function of synaptic engulfment by microglia as a potential avenue to target and resolve microglia heterogeneity in mice with innate high anxiety.

Abstract
Cognitive behavioral therapies have been identified as evidence-based treatments for anxiety-related disorders. However, data supporting the effectiveness of these treatments have been largely collected from participants with majoritized identities, potentially limiting the extent to which they can be considered "evidence-based" for clients from minoritized groups. The current review examined sociodemographic representation and quality of sociodemographic reporting in randomized controlled trials for anxiety-related disorders in the U.S. between 1993 and 2023. We conducted a systematic literature review of U.S.-based randomized controlled trials of cognitive behavioral therapies for anxiety-related disorders, extracted data on sociodemographic variables, and rated quality of reporting. Data from 55 eligible studies (N = 4492) indicated that white and female identities were overrepresented relative to the U.S. population, with variables like disability status, sexual orientation, and religious identification consistently ignored. In addition, quality of reporting was generally poor (mean = 3.6 out of 10), with many studies failing to account for demographic variables in their analyses or description of study limitations. Publication year, sample size, and NIH funding status did not significantly predict gender representation (% women), ethnoracial representation (% white), or quality of reporting. These findings underscore the importance of critically evaluating to whom "evidence-based" treatments apply and increasing diversity of clinical samples, to ensure that evidence-based treatments are inclusive. Recommendations for future research, clinical implications, and limitations are discussed.

Abstract
BACKGROUND/OBJECTIVES Mental health conditions are a leading cause of morbidity and mortality worldwide, with a 13% rise within the last decade. This study aimed to investigate the factors associated with mental illness in patients presenting to a primary healthcare center in the Kingdom of Saudi Arabia (KSA). METHODS Data were extracted from the electronic health records of 46 primary care centers in Riyadh, Saudi Arabia from March 2022 to March 2023. A total of 2418 age-matched mental health cases and controls were evaluated. Descriptive and logistic regression analyses were performed to examine the distribution and association of relevant risk factors. A total of 1209 cases were age-matched to 1209 controls presenting to a primary clinic. RESULTS The odds of mental illness in females were 2.2 times that of males. Clinical conditions associated with mental illness were stroke, diabetes, and obesity. Neurodegenerative disorders were also associated with mental illness. CONCLUSIONS Primary clinics in the KSA can serve as focal points in removing the barriers to mental healthcare. There is an urgent need to spread awareness, remove the stigma, and provide appropriate care and referrals for mental health conditions in the KSA.

Abstract
Stress, which triggers numerous physiological and behavioral responses in the organism, is a significant risk factor that contributes to the development of psychiatric disorders such as depression and anxiety. This study aimed to investigate the inflammation, oxidative stress status, anxiety, and depression-like behaviors of adolescent rodents exposed to chronic intermittent cold stress. Adolescent male rats were subjected to a modified chronic intermittent cold stress model (21 days, 1 hour/day, 4 °C). Depression-like behaviors were evaluated using the sucrose preference and forced swimming tests, while anxiety-like behaviors were assessed using the open field, elevated plus maze, and light-dark box tests. We measured levels of cortisol, tumor necrosis factor-α, interleukin-1β, brain-derived natriuretic factor, reactive oxygen species, malondialdehyde, total oxidants and antioxidants, and other chemicals in the prefrontal cortex, thalamus, striatum, and hippocampus brain regions of rats using ELISA and colorimetric methods. Data were analyzed using Student's t-test and Pearson correlation analysis. After the cold stress treatment, both anxiety and depression-like behaviors increased remarkably in the subjects. Our study revealed significant changes in various brain regions among the stress-exposed subjects. Cold stress resulted in decreased BDNF levels in the prefrontal cortex and striatum (p < 0.05), increased cortisol levels in the prefrontal cortex (p < 0.05), increased IL-1β levels in the hippocampus and thalamus (p < 0.05), increased protein carbonyl levels in the striatum (p < 0.05), and decreased TAS in the prefrontal cortex and thalamus (p < 0.05). Adolescent rats exposed to cold exhibit both anxiety- and depression-like behaviors. This study observed an increase in inflammation in various brain regions, yet the responses to stress varied. Our findings suggest that adolescence is a period of heightened sensitivity to stress, which can lead to dramatic consequences.

Abstract
PURPOSE This study aimed to assess the reliability and validity of the Italian translation of the Unhelpful Thoughts and Beliefs about Stuttering (UTBAS) scales for adults who stutter, as there are no assessment tools currently available in Italy. The UTBAS scales provide a comprehensive stuttering-specific measure of the unhelpful thoughts and beliefs that can be used to screen for indicators of social anxiety in adults who stutter. Additionally, the UTBAS scales also allow the identification of negative thoughts and beliefs that negatively impact speech treatment outcomes. METHOD The translation of the UTBAS scales into Italian (UTBAS-ITA) was completed using the forward-backward translation process and it was administered to 98 adults who stutter (AWS) and 98 adults who do not stutter (AWNS). Both groups were matched for gender and age. We also administered the UTBAS-ITA to 76 AWS a second time within a two-week interval to assess test-retest reliability. Additionally, we administered the State-Trait Anxiety Inventory and the Fear of Negative Evaluation Scale to 20 AWS to assess concurrent validity. RESULTS The UTBAS-ITA showed good power of discrimination between AWS and AWNS, high internal validity, high internal consistency, good construct validity, and good test-retest reliability. CONCLUSION Since there is a scarcity of clinical assessment tools for adults who stutter in Italy, the UTBAS-ITA could serve as an assessment tool and outcome measure for clinical and research environments.

Abstract
BACKGROUND Exposure to stress during childhood and adolescence is a risk factor for alcohol use disorder (AUD) and comorbid conditions, including posttraumatic stress disorder (PTSD). We previously established an adolescent social isolation (SI) model that leads to the emergence of a wide range of behavioral risk factors for AUD, including increased anxiety-like behavior, locomotor activity, and ethanol consumption in male and female rats. Here, we sought to test the hypothesis that SI may increase vulnerability to single prolonged stress (SPS), a rodent model of PTSD. METHODS Female Long Evans rats (n = 8/group) were either single-housed or group-housed (GH) (4/cage) on postnatal day 21. One week later, rats underwent testing in the open field test (OFT), elevated plus-maze (EPM), and successive alleys test (SAT). Following initial behavioral testing, a subset of SI/GH rats were exposed to SPS. All rats were then tested on the novelty-suppressed feeding test (NSFT) followed by fear conditioning and home cage two-bottle choice to assess ethanol consumption. RESULTS SI significantly increased activity in the OFT and anxiety-like behavior on the SAT, but not the EPM. While SI and SPS alone had no effect on the NSFT, exposure to both stressors significantly increased approach latency. Complex effects of stress history were observed across a 3-day fear conditioning paradigm and no group differences were observed with home cage ethanol consumption, regardless of prior ethanol exposure. CONCLUSIONS The results from this study provide novel evidence that SI interacts with SPS in female rats to influence behavior in assays of unconditioned anxiety-like behavior (NSFT) and conditioned fear. Surprisingly, stress exposure had no effect on home cage ethanol consumption. Ultimately, these models provide useful avenues to examine the interaction between stressful experiences, alcohol exposure, biological sex, and the neurobiological adaptations underlying potential risk factors for psychiatric conditions.

Abstract
BACKGROUND The psychological burden of cutaneous malignant melanoma (CM) is all-encompassing, affecting treatment adherence, recurrence and mortality. However, the prevalence and risk factors of anxiety and depression in CM remain unclear. OBJECTIVES To establish a benchmark pooled prevalence of anxiety and depression in CM, to provide magnitudes of association for clinical, therapeutic and demographic correlates, and to elucidate temporal trends in anxiety and depression from the time of diagnosis. METHODS This review followed the MOOSE guidelines. MEDLINE, Embase, PsychINFO, Web of Science and the Cochrane Library were queried from database inception to 24 August 2023. Study selection, data extraction and quality assessment were performed by two independent authors, utilizing both the Joanna Briggs Institute (JBI) and National Institutes of Health risk-of-bias tools for the latter. The GRADE approach was used to rate the certainty of evidence. Prevalence rates, 95% confidence intervals (CIs) and prediction intervals (PIs) were derived using a random-effects model and estimating between- and within-study variance. RESULTS Nine longitudinal and 29 cross-sectional studies were included (7995 patients). Based on the JBI and NIH tools, respectively, quality assessment found 20 and 17 to be at low risk of bias, 12 and 15 to be at moderate risk and 6 and 5 to be at high risk of bias. The prevalence of anxiety [30.6% (95% CI 24.6-37.0; PI 18-47%)] and depression [18.4% (95% CI 13.4-23.9; PI 10-33%)] peaked during treatment, declining to pretreatment levels after 1 year [anxiety: 48% vs. 20% (P = 0.005); depression: 28% vs. 13% (P = 0.03)]. Female sex [odds ratio (OR) 1.8, 95% CI 1.4-2.3; P < 0.001], age < 60 years (OR 1.5, 95% CI 1.2-2.0; P = 0.002) and low educational level (OR 1.5, 95% CI 1.2-2.0; P < 0.001) were likely to result in a large increase in the odds of anxiety. Depression was 12.3% higher in those with stage IV vs. those with stage I CM (P = 0.05). Relative to immune checkpoint inhibition, the rates of depression were 22% (P = 0.002) and 34% (P < 0.001) higher among patients with advanced-stage CM receiving interferon-α and chemotherapy, respectively. A significant reduction in self-reported depression scores was demonstrated over time (P = 0.003). CONCLUSIONS Notably, anxiety and depression in CM affect women, those younger than 60 years of age and the less educated, with up to 80% higher odds of anxiety in these groups. Anxiety and depression surge during chemotherapy and interferon treatment, especially in advanced CM. Our findings facilitate risk stratification and underscore the need for multidisciplinary vigilance.

Abstract
OBJECTIVE This study examined the prevalence and correlates of generalized anxiety disorder (GAD) among primary care outpatients. METHOD A multicenter, cross-sectional study was conducted that included 707 primary care outpatients being seen at 20 primary healthcare centers in Tunis and Sfax, Tunisia. The Mini International Neuropsychiatric Interview was used to identify a diagnosis of GAD. The Beck Depression Inventory was used to assess depressive symptom severity, and the Sheehan Disability Scale (SDS) was used to measure functional impairment. RESULTS The prevalence of GAD was 11%. GAD was positively correlated with female gender (P = .005), family history of psychiatric disorder (P < .001), personal history of suicide attempt (P = .019), and depressive symptoms (P < .001). Based on the SDS, severe to very severe functional limitations were reported at work, in social life, and family life (56.4%, 60.2%, and 73.1%, respectively) among GAD patients. CONCLUSION This study indicated a relatively high prevalence of GAD among primary care patients in Tunisia. Risk factors were also determined that may help to identify these patients. This information may help primary care physicians recognize this diagnosis and provide timely referrals to mental health professionals to prevent complications and preserve quality of life.

Abstract
BACKGROUND Despite the high burden of anxiety and hypertension in Hispanic/Latino adults, little is known about their association in this population. PURPOSE To examine the associations of anxiety symptoms with 6-year changes in blood pressure (BP) and incident hypertension in Hispanic/Latino adults. METHODS We examined data from a probability sample of 10,881 Hispanic/Latino persons aged 18-74 who attended visits 1 (V1; 2008-2011) and 2 (V2; 2014-2017) of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a prospective cohort study. Anxiety symptoms were assessed at V1 using the 10-item Spielberger Trait Anxiety Scale (M = 17.1; Range = 10-40) and dichotomized using a cut-point of 20, the highest quartile in this cohort. BP was measured at both visits using a standardized protocol. RESULTS Adults with elevated anxiety symptoms had a 1.02 mm Hg greater increase in systolic (p = .02) and a 0.75 mm Hg greater increase in diastolic BP (p = .02) over 6.1 years than those with lower symptoms, after adjusting for sociodemographic and clinical covariates. These associations differed by sex. Elevated anxiety was associated with a greater increase in systolic and diastolic BP in men only. Among persons without hypertension at V1 (N = 7,412), those with elevated anxiety symptoms at V1 had a 22% higher incidence of hypertension (p = .02) 6.1 years later. CONCLUSIONS Our findings underscore the importance of screening for and treating elevated anxiety symptoms to help prevent hypertension. Further research on the role of sex and underlying mechanisms is warranted.

Abstract
The population of most countries in the world is increasing and understanding risk factors that can influence the health of the older population is critical. Older adults consume alcohol often in a risky, binge manner. Previous work has demonstrated that aged rats are more sensitive to many of the effects of acute ethanol. In the current project aged, adult, and adolescent female and male rats were tested on the elevated plus maze and open field following either a 1.0 g/kg alcohol injection or a saline injection. We report sex- and age-dependent effects whereas aged female rats, but not aged male rats, showed an increased anxiolytic effect of alcohol in the elevated plus maze while aged male rats, but not aged female rats, showed increased stimulatory movement in the open field. In addition, significant age effects were found for both female and male rats. It is proposed that the sex- and age-dependent effects reported in the current studies may be due to differential levels of alcohol-induced allopregnanolone for the anxiolytic effects and differential levels of alcohol-induced dopamine for the stimulatory effects. The current work provides insights into factors influencing alcohol consumption in older adults.

Abstract
ABSTRACT Injuries and poisoning are associated with mental disorders. The association may be stronger if comorbid mental illness is involved. This study explores whether selected mental disorders (stress, anxiety, depression, attention deficit hyperactivity disorder [ADHD], bipolar, obsessive-compulsive disorder [OCD], schizophrenia) are associated with injuries and poisoning and if the presence and frequency of comorbid mental illness affect these associations. Analyses utilize medical claims data for adult employees of a large corporation during 2017-2021. Approximately half or more of the index mental disorders experience comorbid mental illness. Odds of injury and poisoning are significantly greater for each mental disorder and tend to be significantly greater when comorbid mental illness exists ( vs . the mental disorder alone), especially for the associations involving poisoning. Schizophrenia alone and in combination with other mental illness has the strongest associations with injury and poisoning. OCD is only associated with injury and poisoning, and ADHD is only associated with poisoning, if accompanied by comorbid mental illness.

Abstract
The majority of lifetime smokers begin using nicotine during adolescence, a critical period of brain development wherein neural circuits critical for mood, affect and cognition are vulnerable to drug-related insults. Specifically, brain regions such as the medial prefrontal cortex (mPFC), the ventral tegmental area (VTA), nucleus accumbens (NAc) and hippocampus, are implicated in both nicotine dependence and pathological phenotypes linked to mood and anxiety disorders. Clinical studies report that females experience higher rates of mood/anxiety disorders and are more resistant to smoking cessation therapies, suggesting potential sex-specific responses to nicotine exposure and later-life neuropsychiatric risk. However, the potential neural and molecular mechanisms underlying such sex differences are not clear. In the present study, we compared the impacts of adolescent nicotine exposure in male vs. female rat cohorts. We performed a combination of behavioral, electrophysiological and targeted protein expression analyses along with matrix assisted laser deionization imaging (MALDI) immediately post-adolescent exposure and later in early adulthood. We report that adolescent nicotine exposure induced long-lasting anxiety/depressive-like behaviors, disrupted neuronal activity patterns in the mPFC-VTA network and molecular alterations in various neural regions linked to affect, anxiety and cognition. Remarkably, these phenotypes were only observed in males and/or were expressed in the opposite direction in females. These findings identify a series of novel, sex-selective biomarkers for adolescent nicotine-induced neuropsychiatric risk, persisting into adulthood.

The lived experiences and treatment needs of women with opioid use disorder and posttraumatic stress symptoms: A mixed methods study. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2024; 161:209344. [PMID: 38492805 PMCID: PMC11146521 DOI: 10.1016/j.josat.2024.209344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 02/07/2024] [Accepted: 03/12/2024] [Indexed: 03/18/2024]
Abstract
INTRODUCTION Women show a gender-specific risk for co-occurring opioid use disorder (OUD) and posttraumatic stress disorder (PTSD). Expert groups have called for the development of integrated treatments for women with OUD/PTSD, but there remains limited information on such interventions. METHODS This mixed-methods study interviewed and surveyed 10 women with current or past OUD and co-occurring posttraumatic stress symptoms (PTSS) and 16 providers who work with these women. Interviews and surveys queried patient participants' and providers' experiences of OUD/PTSS and how to best design an integrated, trauma-focused treatment for OUD/PTSD. RESULTS Patient participants (90 % white, 90 % mothers, Mage = 45.70) met criteria for severe, lifetime OUD and 40 % met a provisional diagnosis for PTSD. Four themes emerged for participants' experiences of OUD/PTSS: 1) numerous stressors; 2) shame; 3) multiple motivations to use opioids; and 4) a cycle of trauma and opioid use. Four themes emerged regarding patient participants' perceptions on the development of an OUD/PTSD treatment: 1) mixed attitudes towards medications for OUD; 2) barriers to treatment (e.g., insufficient treatments and contextual factors); 3) treatment facilitators (e.g., social support); and 4) preferences in treatment (e.g., trauma-focused, gender-focused, family content, ambivalence around group therapy). Providers (Mage = 38.94) were primarily white women (76.5 %). Two themes emerged from their experiences working with women with OUD/PTSS: 1) perceiving women to use opioids to regulate emotions and 2) gender differences in trauma types. Three themes emerged for providers' perceptions on the development of an OUD/PTSD treatment: 1) barriers to treatment (e.g., chaotic lives, contextual factors, family); 2) treatment facilitators (e.g., trust and external motivations); and 3) desired treatment modifications (e.g., stabilization, early skills in therapy, flexibility in therapy, social supports, safety guidelines, and assistance in identifying an index trauma). Most participants (90.0 %) and providers (93.5 %) preferred working on OUD/PTSD symptoms simultaneously rather than separately. CONCLUSIONS Findings demonstrate the need to modify integrated treatments to meet the preferences of providers and women with OUD/PTSS and OUD/PTSD. Treatments should consider therapeutic content, structure, contextual factors, social support, and PTSD severity to enhance uptake and reach.

Abstract
BACKGROUND Eosinophilic oesophagitis (EoE) is a chronic, immune-mediated disease of the oesophagus. Eosinophilic oesophagitis is associated with a substantial disease burden affecting the quality of life and affecting mental health. There are limited data describing the incidence of psychiatric disorders and the use of psychotropic drugs (PDs) in EoE patients. OBJECTIVES The aim was to investigate whether EoE patients in Denmark have higher use of PDs, contacts with the department of psychiatry, and attempts of suicide or intentional self-harm compared with the general population after being diagnosed with EoE. METHODS This study was a nationwide, population-based register study including 3367 EoE patients and 16,835 age- and sex-matched comparators. A register-based EoE definition was used to identify cases. Incident PD use was extracted from the prescription register and information regarding psychiatric contacts was retrieved from the Danish Psychiatric Central Research Register. RESULTS The 5-year incidence of PD use in EoE patients was 13.8% compared to 7.1% of the matched comparators (Hazard ratio 1.83; confidence interval 1.6-2.0; p ≤ 0.001). Antidepressants were the most frequently prescribed PD, whereas antipsychotics were the least prescribed PD. Increasing age, lower educational level, and comorbidity (Charlson Comorbidity Index score ≥1) were associated with the prescription of PDs. The risk of PD use was lower in men than in women with EoE. CONCLUSION Treatment with PDs were more common in EoE patients after they were diagnosed than in the general Danish population, indicating that EoE patients have an increased risk of psychiatric disorders.

Abstract
INTRODUCTION Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition with a worldwide prevalence between 6% and 9%, and more common in the female than in the male sex. The aim of this paper is to review and comment on the different factors that might explain the discrepancies in the pharmacological management of women and men. AREAS COVERED The available literature shows that there exists a vulnerability of women to develop PTSD that may depend on neurobiological as well as environmental/cultural factors. These variables might influence the clinical picture, the outcome and the response to specific treatments, given their consequences on the pharmacokinetics of commonly prescribed drugs. Women suffering from PTSD are more prone to consult and receive more prescriptions of psychotropic drugs than men. However, it is evident that the particular stages of a women's life such as pregnancy or breastfeeding might require a specific evaluation and care. EXPERT OPINION It is necessary to explore the pharmacokinetics of compounds highlighting sex-related differences, and their safety during pregnancy and lactation. Taking care of differences between women and men should represent a main focus of research, while being a primary target towards a really tailored pharmacological treatment of PTSD.

Abstract
BACKGROUND Mental health problems among adolescents is a global challenge. During the transition to adolescence, physiological, psychological, and social changes occur, leading to increased vulnerability. Thus, adolescent boys are less likely to seek help for mental health problems, which makes them an undetected group. The aim of this study was to gain a deeper understanding of adolescent boys' experiences of mental health and school health service. METHODS An inductive, qualitative design was chosen using three focus group interviews and three individual interviews. The study included 18 adolescent boys in 7th grade, in a school located in a medium-sized municipality in Norway. The interviews were analysed with qualitative content analysis. The consolidated criteria for reporting qualitative research (COREQ) were followed in this study. RESULTS The overall theme "barriers towards seeking help", and three categories- navigating stigma and privacy concerns; perceptions of self-responsibility; and lacking knowledge of mental health problems and help-seeking-described the adolescent boys experiences. The awareness and willingness to seek help were present, but there are barriers preventing the adolescent boys from acting on that willingness. CONCLUSIONS Lack of knowledge and a non-permissive culture for mental health problems among adolescents contributes to decreased help-seeking behaviour among adolescent boys. The school health service is the most related health service for adolescents and should focus on being available and strengthening empowerment and mental health literacy through the development and implementation of interventions to promote mental health.

Abstract
Introduction Originally published in the United States of America in 1991, the Personality Assessment Inventory (PAI) has been translated and adapted to a growing number of countries, but Portugal had yet to study its adequacy to the Portuguese population. Methods The current study aimed to investigate the Portuguese normative data, the predictive effect of sociodemographic variables on the PAI scores, and the reliability of the Portuguese version of the PAI. Additionally, results were compared with other international versions of the PAI. The sample was comprised of 900 participants (age: M = 43.13, SD = 14.28, range = 18-75), recruited from various regions of Portugal. Results Findings showed that the Portuguese sample scored higher than the U.S. and other international versions of the PAI in most scales. Sociodemographic variables (e.g., gender, age, and educational level) were significant predictors on PAI scores. The internal consistency of the Portuguese sample revealed lower values on the validity scales, but adequate on the clinical, treatment, and interpersonal scales. Overall, the Portuguese PAI revealed adequate psychometric properties, with normative results often superior to other international versions of the inventory. Discussion It is a crucial step into the Portuguese adaptation and validation of this instrument, a measure with considerable potential in clinical, forensic, and research contexts. This adaptation may lead to the growth and development of the psychological assessment field in Portugal, and the opportunity to develop future cross-cultural studies with other international versions of the PAI.

Clinical Features and Disease Activity in Psoriatic Arthritis: A Sex-Related Perspective on Leptin and Comorbidity. J Clin Med 2024; 13:2959. [PMID: 38792501 PMCID: PMC11121807 DOI: 10.3390/jcm13102959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 05/04/2024] [Accepted: 05/16/2024] [Indexed: 05/26/2024] Open
Abstract
Background/Objectives: Many studies have addressed the sex differences in patients with psoriatic arthritis, although these are aimed more at describing the phenotype than at investigating the causes underlying these differences. The aims of our study were to assess the presence of clinical features in relation to sex, and to measure the effect on disease activity of different comorbidities in each sex. Methods: This was a cross-sectional study in which the following factors were measured: the clinical features of the disease, disease activity, the physical function and the disease impact. We measured serum leptin levels, to eliminate the effect of obesity on leptin levels, and a leptin/BMI ratio was calculated. The comorbid conditions evaluated included anxiety and depression, and sleep quality. Results: A total of 203 patients participated in this study. The mean age was 54.6 ± 11.3, and 46.8% of the patients were women. Women less frequently presented axial involvement (8% vs. 28%; p < 0.001) and more commonly had enthesitis (2 vs. 0.3; p < 0.001). They also had higher DAPSA (16.4 vs. 13.4; p < 0.001) and PsAID12 scores (4.1 vs. 2.9; p < 0.001), worse HAQ results (0.8 vs. 0.5; p < 0.001), and greater FACIT-F scores (32.7 vs. 38.1; p < 0.001). As for the comorbid conditions, women presented a higher leptin/BMI ratio (0.8 vs. 0.2; p < 0.001), higher levels of HADS-A (6.9 vs. 4.7; p < 0.001) and HADS-D (4.9 vs. 3.4; p < 0.001), and poorer ISI (9.3 vs. 7.0; p < 0.001). By sex, pain affecting women was associated with the leptin/BMI ratio (β: 0.29; p < 0.004; 95%CI: 0.3-1.6) and sleep quality (β: 0.31; p < 0.004; 95%CI: 0.04-0.25; R2: 0.26). The leptin/BMI ratio was not associated with pain in men (p = 0.46). Conclusions: Sex was associated with several clinical manifestations. Leptin/BMI ratio levels were associated with pain in women, but not in men.

Abstract
The Anxiety Scale for Autism-Adults (ASA-A) captures the autistic anxiety experience, but we do not know whether it is structurally equivalent for men and women, or non-autistic people. Measurement invariance analysis considered gender and diagnostic status (342 cis-gender autistic men (N = 105) and women (N = 237), 316 cis-gender non-autistic men (N = 104) and women (N = 212)). Strict invariance was achieved between autistic men and women and between non-autistic men and women, but the ASA-A structure is quantitatively different in autistic compared to non-autistic adults. Therefore, this tool cannot be used to directly compare anxiety between these groups. Autistic women scored significantly higher on the ASA-A than autistic men and Uncertainty was the highest scoring factor for autistic participants. Future research should include alternative gender identities.

Abstract
Introduction During the COVID-19 pandemic individuals with mental illnesses faced challenges accessing psychiatric care. Our study aimed to describe patient characteristics and compare admissions and length of stay (LOS) for psychiatric-related hospitalizations before and during the COVID-19 pandemic. Methods We conducted a retrospective analysis using health administrative data comparing individuals with an acute psychiatric admission between two time periods: 1st March 2019 to 31st December 2019 (pre-COVID) and 1st March 2020 to 31st December 2020 (during-COVID). Multivariable negative binomial regression was used to model the association between most responsible diagnosis type and the two-time periods to hospital LOS, reporting the Rate Ratio (RR) as the measure of effect. Results The cohort comprised 939 individuals who were predominately male (60.3%) with a severe mental illness (schizophrenia or mood-affective disorder) (72.7%) and a median age of 38 (IQR: 28.0, 52.0) years. In the multivariable analysis, anxiety disorders (RR: 0.63, CI: 0.4, 0.99) and personality disorders (RR: 0.52, CI: 0.32, 0.85) were significantly associated with a shorter LOS when compared to individuals without those disorders. Additionally, when compared to hospital admissions for non-substance related disorders the LOS for patients with substance-related disorders were significantly shorter during the COVID period (RR: 0.45, CI: 0.30, 0.67) and pre-COVID period (RR: 0.31, CI: 0.21, 0.46). Conclusions We observed a significant difference in the type and length of admissions for various psychiatric disorders during the COVID-19 period. These findings can support systems of care in adapting to utilization changes during pandemics or other global health events.

Abstract
Obesity, associated with the intake of a high-fat diet (HFD), and anxiety are common among those living in modern urban societies. Recent studies suggest a role of microbiome-gut-brain axis signaling, including a role for brain serotonergic systems in the relationship between HFD and anxiety. Evidence suggests the gut microbiome and the serotonergic brain system together may play an important role in this response. Here we conducted a nine-week HFD protocol in male rats, followed by an analysis of the gut microbiome diversity and community composition, brainstem serotonergic gene expression (tph2, htr1a, and slc6a4), and anxiety-related defensive behavioral responses. We show that HFD intake decreased alpha diversity and altered the community composition of the gut microbiome in association with obesity, increased brainstem tph2, htr1a and slc6a4 mRNA expression, including in the caudal part of the dorsomedial dorsal raphe nucleus (cDRD), a subregion previously associated with stress- and anxiety-related behavioral responses, and, finally, increased anxiety-related defensive behavioral responses. The HFD increased the Firmicutes/Bacteroidetes ratio relative to control diet, as well as higher relative abundances of Blautia, and decreases in Prevotella. We found that tph2, htr1a and slc6a4 mRNA expression were increased in subregions of the dorsal raphe nucleus in the HFD, relative to control diet. Specific bacterial taxa were associated with increased serotonergic gene expression in the cDRD. Thus, we propose that HFD-induced obesity is associated with altered microbiome-gut-serotonergic brain axis signaling, leading to increased anxiety-related defensive behavioral responses in rats.

Abstract
Background: A water extract (CAW) of the Ayurvedic plant Centella asiatica administered in drinking water has been shown to improve cognitive deficits in mouse models of aging and neurodegenerative diseases. Here the effects of CAW administered in drinking water or the diet on cognition, measures of anxiety and depression-like behavior in healthy aged mice are compared. Methods: Three- and eighteen-month-old male and female C57BL6 mice were administered rodent AIN-93M diet containing CAW (0, 0.2, 0.5 or 1% w/w) to provide 0, 200 mg/kg/d, 500 mg/kg/d or 1,000 mg/kg/d CAW for a total of 5 weeks. An additional group of eighteen-month-old mice were treated with CAW (10 mg/mL) in their drinking water CAW for a total of 5 weeks to deliver the same exposure of CAW as the highest dietary dose (1,000 mg/kg/d). CAW doses delivered were calculated based on food and water consumption measured in previous experiments. In the fourth and fifth weeks, mice underwent behavioral testing of cognition, anxiety and depression (n = 12 of each sex per treatment group in each test). Results: Aged mice of both sexes showed cognitive deficits relative to young mice while only female aged mice showed increased anxiety compared to the young female mice and no differences in depression were observed between the different ages. CAW (1,000 mg/kg/d) in the drinking water improved deficits in aged mice in learning, executive function and recognition memory in both sexes and attenuated the increased measures of anxiety observed in the aged female mice. However, CAW in the diet only improved executive function in aged mice at the highest dose (1,000 mg/kg/d) in both sexes and did so less robustly than when given in the water. There were no effects of CAW on depression-like behavior in aged animals regardless of whether it was administered in the diet or the water. Conclusions: These results suggest that CAW can ameliorate age-related changes in measures of anxiety and cognition and that the mode of administration is important for the effects of CAW on resilience to these age-related changes.

Abstract
Background: Anxiety disorders are prevalent mental health conditions often accompanied by various comorbidities. The association between anxiety and liver disease, as well as fluctuations in blood sugar levels, highlights the importance of carefully evaluating patients with anxiety undergoing antidepressant therapy. The aim of this study was to conduct a comparative assessment of liver function and blood glucose levels in patients diagnosed with anxiety disorders while considering potential gender-specific differences. Methods: An analysis was conducted over a 24-month period. This study included 88 patients diagnosed with anxiety disorders, with symptoms severe enough to require hospitalization, aged 18 or older, undergoing antidepressant monotherapy, without any additional pathologies. Liver enzymes (AST, ALT, GGT), AST/ALT ratio, and blood glucose levels were measured and compared. Results: While no significant differences were found between antidepressant classes, increased GGT levels were observed in men older than 40 years compared to women of the same age, suggesting that alcohol consumption may be a coping mechanism for anxiety. This gender difference was not observed among young patients. Conclusions: Early detection of alcohol consumption is essential in patients with anxiety disorders in order to prevent alcohol-related liver damage and to adjust the management of both conditions accordingly.

Abstract
This review aims to argue how using probiotics can improve anxiety and depressive behaviour without adverse effects, also exploring the impact of postbiotics on it. Specifically, probiotics have drawn more attention as effective alternative treatments, considering the rising cost of antidepressant and anti-anxiety drugs and the high risk of side effects. Depression and anxiety disorders are among the most common mental illnesses in the world's population, characterised by low mood, poor general interest, and cognitive or motor dysfunction. Thus, this study analysed published literature on anxiety, depression, and probiotic supplementation from PubMed and Scopus, focusing on the last twenty years. This study focused on the effect of probiotics on mental health as they have drawn more attention because of their extensive clinical applications and positive impact on various diseases. Numerous studies have demonstrated how the gut microbiota might be critical for mood regulation and how probiotics can affect host health by regulating the gut-brain axis. By comparing the different works analysed, it was possible to identify a strategy by which they are selected and employed and, at the same time, to assess how the effect of probiotics can be optimised using postbiotics, an innovation to improve mental well-being in humans.

Doll‐Lee J, Passarotto E, Altenmüller E, Lee A. Gender Differences in Task Specific Dystonia: What Can we Learn from Musician's Dystonia? Mov Disord Clin Pract 2024; 11:526-533. [PMID: 38469936 PMCID: PMC11078487 DOI: 10.1002/mdc3.14015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 01/07/2024] [Accepted: 02/13/2024] [Indexed: 03/13/2024] Open
Abstract
BACKGROUND Musician's Dystonia (MD) is a task specific, focal dystonia which usually occurs only at the instrument. The pathophysiology is not fully understood, but several risk factors like over-practice and genetic predisposition are known. Interestingly, 80% of those affected are men, which stands in contrast to the gender distribution in other focal dystonias, such as cervical dystonia. OBJECTIVES Our aim was to evaluate the difference in women and men with regard to risk factors leading to MD. METHODS We investigated known risk factors for MD in a large cohort of 364 MD patients by retrospectively collecting data on practice behavior and family history. RESULTS In line with previous studies, we found a ratio of ~4:1 men to women. Age at onset of MD was significantly lower in women; however, subsequent analysis revealed that it was a positive family history (FH+) and not gender that was associated with a lower age at onset. Furthermore, we found that those with negative family history had accumulated more practice time until onset of MD. CONCLUSIONS These results imply that the earlier age at onset in women did not depend on gender but was due to the higher proportion of a positive family history. In contrast, men were less likely to have a positive family history, suggesting that genetic factors may not be the primary reason for the higher prevalence of MD in men. Instead, differences in practice behaviors between men and women may contribute to this gender disparity.

Dorsal peduncular cortex activity modulates affective behavior and fear extinction in mice. Neuropsychopharmacology 2024; 49:993-1006. [PMID: 38233571 PMCID: PMC11039686 DOI: 10.1038/s41386-024-01795-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 12/27/2023] [Accepted: 12/28/2023] [Indexed: 01/19/2024]
Abstract
The medial prefrontal cortex (mPFC) is critical to cognitive and emotional function and underlies many neuropsychiatric disorders, including mood, fear and anxiety disorders. In rodents, disruption of mPFC activity affects anxiety- and depression-like behavior, with specialized contributions from its subdivisions. The rodent mPFC is divided into the dorsomedial prefrontal cortex (dmPFC), spanning the anterior cingulate cortex (ACC) and dorsal prelimbic cortex (PL), and the ventromedial prefrontal cortex (vmPFC), which includes the ventral PL, infralimbic cortex (IL), and in some studies the dorsal peduncular cortex (DP) and dorsal tenia tecta (DTT). The DP/DTT have recently been implicated in the regulation of stress-induced sympathetic responses via projections to the hypothalamus. While many studies implicate the PL and IL in anxiety-, depression-like and fear behavior, the contribution of the DP/DTT to affective and emotional behavior remains unknown. Here, we used chemogenetics and optogenetics to bidirectionally modulate DP/DTT activity and examine its effects on affective behaviors, fear and stress responses in C57BL/6J mice. Acute chemogenetic activation of DP/DTT significantly increased anxiety-like behavior in the open field and elevated plus maze tests, as well as passive coping in the tail suspension test. DP/DTT activation also led to an increase in serum corticosterone levels and facilitated auditory fear extinction learning and retrieval. Activation of DP/DTT projections to the dorsomedial hypothalamus (DMH) acutely decreased freezing at baseline and during extinction learning, but did not alter affective behavior. These findings point to the DP/DTT as a new regulator of affective behavior and fear extinction in mice.

Abstract
Trait anxiety is a major risk factor for stress-induced and anxiety disorders in humans. However, animal models accounting for the interindividual variability in stress vulnerability are largely lacking. Moreover, the pervasive bias of using mostly male animals in preclinical studies poorly reflects the increased prevalence of psychiatric disorders in women. Using the threat imminence continuum theory, we designed and validated an auditory aversive conditioning-based pipeline in both female and male mice. We operationalised trait anxiety by harnessing the naturally occurring variability of defensive freezing responses combined with a model-based clustering strategy. While sustained freezing during prolonged retrieval sessions was identified as an anxiety-endophenotype behavioral marker in both sexes, females were consistently associated with an increased freezing response. RNA-sequencing of CeA, BLA, ACC, and BNST revealed massive differences in phasic and sustained responders' transcriptomes, correlating with transcriptomic signatures of psychiatric disorders, particularly post-traumatic stress disorder (PTSD). Moreover, we detected significant alterations in the excitation/inhibition balance of principal neurons in the lateral amygdala. These findings provide compelling evidence that trait anxiety in inbred mice can be leveraged to develop translationally relevant preclinical models to investigate mechanisms of stress susceptibility in a sex-specific manner.

BIOLOGY 2024; 13:303.

Abstract
Stress is an important risk factor for the onset of anxiety and depression. The ability to cope with stressful events varies among different subjects, probably depending on different genetic variants, sex and previous life experiences. The Val66Met variant of Brain-Derived Neurotrophic Factor (BDNF), which impairs the activity-dependent secretion of BDNF, has been associated with increased susceptibility to the development of various neuropsychiatric disorders. Adult male and female wild-type Val/Val (BDNFV/V) and heterozygous Val/Met (BDNFV/M) mice were exposed to two sessions of forced swimming stress (FSS) per day for two consecutive days. The mice were behaviorally tested 1 day (short-term effect) or 11 days (long-term effect) after the last stress session. Protein and mRNA levels were measured in the hippocampus 16 days after the end of stress exposure. Stressed mice showed a higher anxiety-like phenotype compared to non-stressed mice, regardless of the sex and genotype, when analyzed following the short period of stress. In the prolonged period, anxiety-like behavior persisted only in male BDNFV/M mice (p < 0.0001). Interestingly, recovery in male BDNFV/V mice was accompanied by an increase in pCREB (p < 0.001) and Bdnf4 (p < 0.01) transcript and a decrease in HDAC1 (p < 0.05) and Dnmt3a (p = 0.01) in the hippocampus. Overall, our results show that male and female BDNF Val66Met knock-in mice can recover from subchronic stress in different ways.
