Purpose of review: This review discusses the current and projected landscape of psychedelic-assisted therapy (PAT), with a focus on clinical, legal, and implementation considerations in Department of Defense (DoD) and Department of Veterans Affairs (VA) healthcare systems.

Recent findings: 3,4-Methylenedioxymethamphetamine (MDMA)- and psilocybin-assisted therapy have shown promising outcomes in efficacy, safety, tolerability, and durability for PTSD and depression, respectively. MDMA-assisted therapy is already approved by the Food and Drug Administration (FDA) on an Expanded Access ("compassionate use") basis for PTSD, with full approval projected for 2024. Psilocybin-assisted therapy is projected to be FDA-approved for depression soon thereafter. Other psychedelics are in earlier stages of development. The VA is currently conducting PAT clinical trials. Although there are clear legal pathways for the VA and DoD to conduct PAT trials, a number of implementation barriers exist, such as the very high number of clinical hours necessary to treat each patient, resource requirements to support treatment infrastructure, military-specific considerations, and the high level of evidence necessary for PAT to be recommended in clinical practice guidelines. Ongoing considerations are whether and how PAT will be made available to VA and DoD beneficiaries, feasibility and cost-effectiveness, and ethical safeguards that must be implemented to prioritize access to PAT given the likelihood of extremely limited initial availability. However, with imminent FDA approval of PATs and considerable national interest in these treatments, DoD and VA policymakers must be prepared with clearly delineated policies and plans for how these healthcare systems will approach PAT.

Purpose of review: We systematically reviewed and meta-analyzed the literature on the relationship between early maladaptive schemas (EMSs) and Cluster C personality disorders (PDs). Our aim was to clarify which of the 18 EMSs exhibit the strongest associations and are most frequently endorsed in clinical and non-clinical samples with Cluster C PDs and traits.

Recent findings: After initially screening 2622 records, 12 studies were selected with 5310 participants. Meta-analyses of the raw correlation coefficients for each EMS-Cluster C PD link (3-8 studies per meta-analysis) indicated that the 18 EMSs were significantly related to all three Cluster C PDs with r's ranging from .13 to .63. However, when considering endorsement rates among multiple regression studies that controlled for the EMSs intercorrelations and the effects of other PD traits and demographics, specific EMS constellations emerged for each Cluster C PD. Overall, the findings of the current paper suggest that Cluster C PDs might be conceptualized on the basis of a hybrid EMS model, in which all EMSs contribute to global personality dysfunction whereas specific EMS patterns reflect unique personality disorder style expressions. Longitudinal research with appropriate methodology is needed to draw more definite conclusions on the EMSs-Cluster C PDs relationships.

Purpose of review: To summarize current literature available on sleep in 22q11.2 Deletion Syndrome (22q11.2DS; Velocardiofacial or DiGeorge Syndrome), a neurogenetic disorder caused by a hemizygous deletion in a genomic region critical for neurodevelopment. Due to the greatly increased risk of developmental psychiatric disorders (e.g., autism and schizophrenia) in 22q11.2DS, this review focuses on clinical correlates of sleep disturbances and potential neurobiological underpinnings of these relationships.

Recent findings: Sleep disturbances are widely prevalent in 22q11.2DS and are associated with worse behavioral, psychiatric, and physical health outcomes. There are reports of sleep architecture and sleep neurophysiology differences, but the literature is limited by logistical challenges posed by objective sleep measures, resulting in small study samples to date. Sleep disturbances in 22q11.2DS are prevalent and have a substantial impact on well-being. Further investigation of sleep in 22q11.2DS utilizing multimodal sleep assessments has the potential to provide new insight into neurobiological mechanisms and a potential trans-diagnostic treatment target in 22q11.2DS.

Purpose of review: Pregnancy denial is the lack of awareness of being pregnant. The aim of the review is to understand why the affected women do not recognize the signs of pregnancy.

Recent findings: Twelve case reports of pregnancy denial were published in the last ten years. While in five cases the women had an underlying mental disorder, the rest of the cases involved women who either exhibited no physical symptoms or perceived themselves to be not pregnant despite the symptoms (i.e., repression mechanisms). Pregnancy denial is considered to be a pathological issue, a likely consequence of trauma, the wish to not have a child, or a psychiatric problem. However, it appears that the majority of cases cannot be linked to any of the above reasons. We argue, therefore, that, in most cases, pregnancy denial is not associated with mental or physiological problems. Under certain circumstances, it can affect any woman.

Purpose of review: This article seeks to provide a broad overview of the workplace mental health literature, highlight practical implications of current research, and formulate key recommendations for stakeholders. Various aspects of disability related to mental health disorders, their associated financial costs, and the impact of stigma are covered. This article also discusses key strategies for assessing mental health problems among employees and reviews different types of interventions in the workplace.

Recent findings: Workplace mental health is an evolving area, particularly in the wake of the pandemic. While established national workplace mental health standards do not currently exist, mental illness continues to have a severe impact on the health of organizations, employees, and the economy. Additional research is needed to fully understand and address the diversity of mental health needs among the broad range of employees and organizations across the USA. Employers have a responsibility and an opportunity to create workplaces that support the whole person, not just the employee. While research in the area has increased in the last decade, there is still much to learn in terms of the most effective ways to support our workforce.

Purpose of review: While there are reports of differences in emotion processing in autism, it is less understood whether the emotion of disgust, in particular, plays a significant role in these effects. Here, we review literature on potential disgust processing differences in autism and its possible associations with autistic traits.

Recent findings: In autism, there is evidence for differences in physical disgust processing, pica behaviors, attention away from other's disgust facial expressions, and differences in neural activity related to disgust processing. In typically developing individuals, disgust processing is related to moral processing, but modulated by individual differences in interoception and alexithymia. Autistic individuals may experience atypical disgust, which may lead to difficulty avoiding contaminants and affect socio-emotional processing. In autism, such outcomes may lead to increased occurrences of illness, contribute to gastrointestinal issues, diminish vicarious learning of disgust expression and behaviors, and potentially contribute to differences in processes related to moral reasoning, though further research is needed.

Purpose of review: To review recent research regarding cognitive problems during perimenopause, including which menopause-related symptoms, demographic variables, stress exposures, and neural biomarkers are associated with cognitive problems and which interventions demonstrate efficacy at improving cognitive performance.

Recent findings: Cognitive problems are common during perimenopause and have a significant impact on a substantial proportion of women. Evidence continues to indicate that verbal learning and verbal memory are the cognitive functions that are most negatively affected during perimenopause, and new research suggests that perimenopause may also be associated with deficits in processing speed, attention, and working memory. Recent research suggests that the cognitive profiles of women transitioning through perimenopause are heterogenous - with some showing strengths and others demonstrating weaknesses in particular cognitive domains. Depression, sleep problems, and vasomotor symptoms in perimenopause may be associated with cognitive difficulties. Recent neuroimaging studies are identifying changes in activity patterns within brain regions that correlate with cognitive performance in perimenopause, but future causal studies are needed to understand the neural mechanisms of cognitive problems during this time. Although clinical treatment studies for cognitive concerns have historically focused on postmenopause, some small trials in perimenopausal samples have been conducted recently but are frequently underpowered. Current guidelines from the North American Menopause Society do not support the use of hormone therapy at any age for cognitive problems. Animal research demonstrates that estradiol and levonorgestrel combined may alleviate working memory problems. Much progress has been made in understanding how perimenopause impacts cognition, and more research is needed to better identify who is at highest risk and how to meaningfully prevent and alleviate cognitive problems during this reproductive stage. Larger-scale randomized intervention trials specifically during perimenopause are urgently needed to address cognitive concerns in this population of women. More consistent reproductive staging, inclusion of covariates, and analyses examining perimenopause specifically would improve study quality and the ability to draw clear conclusions from this research.

Purpose of review: The purpose of this review is to summarize factors contributing to the current state of pediatric mental health access in ED settings and synthesize the existing literature on the use of telepsychiatry to extend access to care, with particular focus on feasibility and sustainability.

Recent findings: Children are presenting to emergency departments (EDs) with mental health concerns at an increasing rate, while ED capacity to treat psychiatric needs in children remains insufficient. This growing problem is compounded by decreased access to outpatient care and inpatient psychiatric beds, resulting in exorbitantly long waiting times, or "boarding," of children in crisis. Telepsychiatry has emerged as a strategy to decrease boarding of pediatric patients in ED settings by utilizing remote psychiatric professionals to provide consultation and assessment. Telepsychiatry in ED settings is an effective strategy to increase access to care and decrease length of stay for pediatric patients.

Purpose of review: This systematic review aimed to distil recent literature investigating psychosocial factors which may account for the association between personality disorder (PD) and suicide attempt or suicide death.

Recent findings: Suicide risk is particularly elevated in people with PD compared to those with no, or many other, mental health diagnoses. Despite this, suicide prevention strategies for PD populations have not progressed markedly in recent years. It is critical, therefore, to identify additional factors associated with suicide in PD populations. Of the 34 studies included in this review, most identified a relationship between personality disorder and suicide attempt and/or death. Historical interpersonal factors (e.g., childhood trauma), drug and alcohol use, and ideation-to-enaction factors were commonly associated with suicide-related outcomes. Interventions that provide interpersonal support may reduce suicide attempts. Limitations of the review include the heterogeneity of studies and small sample sizes.
