Val/Met BDNF as a genetic risk for a false sense of security in post-discharge suicide risk. J Affect Disord 2024; 354:98-103. [PMID: 38447916 DOI: 10.1016/j.jad.2024.03.001] [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: 11/15/2023] [Revised: 02/14/2024] [Accepted: 03/03/2024] [Indexed: 03/08/2024]
Abstract
BACKGROUND The time after discharge from psychiatric inpatient care is one of the most dangerous periods in terms of suicide risk. Predicting who is at higher risk could help with resource allocation to assure patients at high risk of suicide attempts are most closely followed. We previously showed that inpatients who improve their suicide ideation levels faster while in inpatient treatment are the ones with highest rates of post-discharge suicide. Here, we studied the possible genetic underpinnings associated with such risk. METHOD We recorded the slope of suicide ideation recovery of 710 psychiatric inpatients from which we studied two genetic variants likely associated with suicide risk: The serotonin transporter variant 5-HTTLPR, and the BDNF gene variant Val66Met. RESULTS We found that inpatients carrying the BDNF Met variant (hypothesized as conferring higher suicide risk) improved their suicide ideation scores faster than Val/Val carrying inpatients. No significant association was found for 5-HTTLPR. LIMITATIONS The present sample was genetically homogenous, and future research should replicate these findings on a more diverse sample. CONCLUSIONS In conclusion, we found a paradoxical result: Carrying the BDNF Met variant allows inpatients to improve faster, which was shown to confer higher risk at the post-discharge period. This may explain some inconsistencies in the literature in terms of the role of BDNF in suicide ideation and attempts.

Difficulties in emotion regulation moderates the relationship between mood symptoms and nightmares in an inpatient psychiatric sample. J Affect Disord 2024; 351:179-183. [PMID: 38286228 DOI: 10.1016/j.jad.2024.01.244] [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: 06/09/2023] [Revised: 01/16/2024] [Accepted: 01/26/2024] [Indexed: 01/31/2024]
Abstract
BACKGROUND Emotional processing and regulation of affect are often impaired in psychiatric patients. Nightmares could be considered a manifestation of problems with this process. In the present study, we examined how depression, anxiety and suicidal risk related to difficulties in emotion regulation and nightmares over the course of inpatient treatment. We also explored whether emotion regulation problems moderated the relationship between changes in depression, anxiety, and suicide risk to changes in nightmares from admission to discharge. METHODS The present study included 1215 adults admitted to an inpatient psychiatric hospital ranging from 18 to 87 years of age (M = 37.18, SD = 16.14). Mood symptoms, emotion regulation difficulties, nightmares and suicide risk were assessed at admission and discharge. Moderation analyses were calculated using Model 1 of the PROCESS Macro (Hayes, 2013). RESULTS Moderation analyses showed the associations between depression and nightmares (b = 0.25, p < .001) and suicide and nightmares (b = 0.34, p < .001) were strongest when patients had high levels of emotion regulation difficulties. Emotion regulation difficulties did not, however, moderate the relationship between anxiety and nightmares. Furthermore, improvement in depression and nightmares was significantly related to improvement in emotion regulation difficulties. LIMITATIONS The homogeneity of the sample limits the generalizability of the results. Furthermore, the use of self-report measures, especially sleep related assessments, can bias the data more than objective measures. CONCLUSIONS These findings provide clinical implications when treating psychiatric patients such as a need for emotion regulation skills building.

Abstract
Transgender youth are at an increased risk of suicide, substance use, experiencing violent assaults, and reporting major depressive episodes and greater psychological distress compared to their cisgender counterparts. This study examined mental health symptom severity in adolescents admitted to an inpatient psychiatric hospital who wished they were of a different gender compared to those who did not. A group of 180 adolescents admitted to an inpatient psychiatric hospital completed assessments to measure mental health symptom severity at admission. Gender diverse (n = 90) and cisgender (n = 90) groups were established. Analyses of variance (ANOVA) were used to examine between group (gender diverse vs. cisgender) difference on depression, anxiety, suicide risk, nighttime sleep quality, and emotion regulation problems. Results revealed significant differences in emotion regulation difficulties at admission, specifically in nonacceptance and awareness. There were no significant differences on measures of depression, anxiety, suicide risk, and nighttime sleep quality at admission. This study is one of the first to measure mental health symptom severity in gender diverse adolescents while admitted to an inpatient psychiatric setting. Adolescents in the gender diverse group had significantly higher level of difficulty with emotion regulation, which may indicate an increased risk of developing psychiatric symptoms such as depression and anxiety. This paper demonstrates the importance of using targeted interventions to address difficulties with emotion regulation in at-risk adolescents.

Abstract
STUDY OBJECTIVES The Disturbing Dream and Nightmare Severity Index (DDNSI) has been used widely in research and clinical practice without psychometric evidence supporting its use in clinical samples. The present study aimed to explore and confirm the factor structure of the DDNSI in an inpatient sample. We also sought to test the measure's construct validity. METHODS Two samples of U.S. inpatients including adult (N = 937) and adolescent (N = 274) participants provided data on nightmares (i.e. DDNSI), sleep quality (i.e. the Pittsburgh Sleep Quality Index) and related psychopathology symptoms (e.g. depression, posttraumatic stress disorder, anxiety). RESULTS Exploratory and confirmatory factor analyses found the six original items of the DDNSI to load onto a single latent factor. CONCLUSIONS The DDNSI was found to be a valid measure of nightmare frequency and distress, as it was significantly correlated with the items related to disturbing dreams, and the DDNSI was able to differentiate between nightmares and psychopathology symptoms. Though this research comes nearly two decades after the initial creation and use of the DDNSI, it provides a foundation for the scientific rigor of previous and future studies on nightmares using the DDNSI.

Abstract
OBJECTIVE To assess whether anterior cingulate cortex (ACC) abnormalities contribute to suicide risk in major depressive disorder and bipolar disorder, the investigators compared resting-state functional connectivity (rsFC) of ACC subdivisions between individuals with major depressive or bipolar disorder with and without a lifetime history of suicidal behavior. METHODS Forty-two inpatients with and 26 inpatients without a history of suicidal behavior (SB+ and SB-, respectively) associated with major depressive or bipolar disorder and 40 healthy control (HC) participants underwent rsFC neuroimaging. RsFC of the subgenual, perigenual, rostral, dorsal, and caudal subdivisions of the ACC was calculated. Possible confounders, such as psychosis and severity of depression, were controlled for, seed-to-voxel and post hoc region of interest (ROI)-to-ROI analyses were performed, and the accuracy of rsFC in classifying suicidal behavior was studied. RESULTS Compared with individuals in the SB- and HC groups, patients in the SB+ group had higher rsFC between the left rostral and right dorsal ACC seeds and visual cortex clusters. Conversely, rsFC between the left rostral and right dorsal ACC seeds and cingulate and frontal clusters was lower in the SB+ group than in the HC group. Left rostral ACC to left Brodmann's area 18 connectivity showed up to 75% discriminative accuracy in distinguishing SB+ from SB- patients. CONCLUSIONS A history of suicidal behavior among individuals with major depressive disorder or bipolar disorder was associated with altered rsFC of the rostral and caudal ACC, regions involved in conflict detection and error monitoring. Replication of these findings is needed to further explore the involvement of the ACC in the neurobiology of suicidal behavior and suicidal ideation.

Relationship between parental attachment styles and suicide in adolescents and adults admitted to an inpatient psychiatric hospital. J Affect Disord 2023; 341:170-175.

Abstract
BACKGROUND Suicide is among one of the leading causes of death in the United States affecting individuals of all ages. METHODS We examined the relationship between suicide risk and parental attachment among an inpatient psychiatric sample of 690 adolescents and 1000 adults. Participants completed self-report measures of suicide risk and attachment. RESULTS We found that both adolescents and adults with insecure (i.e., preoccupied, dismissive, fearful) maternal and paternal attachment are at a significantly higher risk of suicide compared to those with secure maternal and paternal attachment. Adolescents who endorsed a previous suicide attempt (27.2 %) were less likely to have a secure maternal attachment, while adults who endorsed a previous suicide attempt (28.9 %) were less likely to have secure paternal attachment. LIMITATIONS Our sample had limited racial and ethnic diversity which may limit the generalizability of the results to a broader population. CONCLUSIONS The present study provides evidence of the importance of parental attachment styles as a predictor of suicide-related behaviors across both adolescents and adults who are admitted inpatient. This suggests the importance of utilizing family-based interventions in order to reduce the risk of suicide.

Abstract
Prior research has demonstrated the strong link between sleep disturbance and mental health outcomes, including the importance of examining nighttime sleep quality and daytime sleepiness as separate constructs in relation to mental health outcomes. As such, the current study examined patients' self-reported nighttime sleep quality and daytime sleepiness trajectories over the course of inpatient treatment and how these trajectories related to treatment outcomes. Participants were 1,500 adults who voluntarily admitted to an inpatient psychiatric hospital. Mental health outcomes measured were emotion regulation problems, anxiety severity, depression severity, nightmare severity, and suicide risk. Group-based trajectory modeling was used to determine nighttime sleep quality and daytime sleepiness trajectory groups. Multivariate analyses of covariance (MANCOVA) were used to determine between group differences on mental health outcomes. Patients fit into distinct groups based on their trajectories of nighttime sleep quality and daytime sleepiness across inpatient psychiatric treatment: Low, Moderate, and High. Individuals with greater nighttime sleep disturbance and greater daytime sleepiness throughout treatment (High group) demonstrated significantly increased suicide risk, higher nightmare severity, more anxiety, more depression, and more emotion regulation difficulties at discharge. Results suggest an important connection exists between nighttime sleep quality and excessive daytime sleepiness and mental health outcomes for inpatient psychiatry.

An Examination of the Treatment Utility of the MMPI-2-RF: Prediction of Post-Treatment Depressive Symptoms and Increased Understanding of the Therapeutic Alliance in an Inpatient Mood Disorder Treatment. J Pers Assess 2023; 105:667-678.

Abstract
The study examined the ability of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) substantive scales to predict depressive symptoms in a psychiatric inpatient setting. The indirect effect of patient-rated alliance with their treatment team on these relationships was also investigated. Participants included 678 (52.5% female, 97.1% White) inpatients diagnosed with a mood disorder. MMPI-2-RF scales, Patient Health Questionnaire (PHQ-9) at intake and discharge, and Working Alliance Inventory-Short at discharge were used to test study hypotheses regarding MMPI-2-RF predictive utility and the influence of alliance. Jacobson and Truax's (1991) reliable change index (RCI) was calculated to identify those who did (74% of the sample) and did not (24%) make reliable and clinically significant depressive symptom change, and the predictive utility of MMPI-2-RF scores in distinguishing these groups was examined. MMPI-2-RF scales assessing internalizing and somatic dysfunction accounted for an additional 2% to 8% of the variance in depressive symptoms reported at discharge, above and beyond depressive symptoms reported at intake. Somatic scales were also able to differentiate groups based on clinically significant change on the PHQ-9 (small-sized effect). The relationship between MMPI-2-RF scales and depressive symptoms at discharge was indirect through alliance in 64% of models. Clinical implications are discussed.

Reward Processing in Psychiatric Inpatients With Depression. BIOLOGICAL PSYCHIATRY. COGNITIVE NEUROSCIENCE AND NEUROIMAGING 2023; 8:731-740.

Abstract
BACKGROUND Previous neuroimaging studies have investigated reward-processing dysfunction in major depressive disorder and have led to the common finding that major depressive disorder is associated with reduced reward responses within the reward circuit. Yet it is unclear whether such reward-processing dysfunction is specifically associated with the severity of depressive symptoms in major depressive disorder or is associated with common comorbidities. METHODS We investigated reward-processing differences using a classic juice-delivery functional magnetic resonance imaging experiment to compare psychiatric patients with severe depressive symptoms (DEPs) to both psychiatric control subjects (PCs) and healthy control subjects. In this study, the DEPs (n = 108) were matched to healthy control subjects (n = 62) for demographic characteristics and to the PCs (n = 108) for demographics and comorbid psychiatric diagnoses. An a priori region of interest, the left putamen, was selected using previous studies. An exploratory whole-brain analysis was performed to explore for nonhypothesized regions. RESULTS Relative to the PCs and healthy control subjects, the DEP group showed smaller responses to reward stimulus in the left putamen. Whole-brain exploratory analysis revealed that DEPs had significantly lower responses to reward stimulus in the bilateral dorsal striatum (putamen and caudate), middle frontal gyrus, left precentral gyrus, and middle cingulate cortex than PCs. CONCLUSIONS Our findings suggest that DEPs may have a lesser ability to modulate behavior as a function of reward, especially in those individuals who experience the most severe depressive symptoms. In both DEPs and PCs, the severity of depressive symptoms was related to reduced reward responses in the left putamen.

miR-124-3p target genes identify globus pallidus role in suicide ideation recovery in borderline personality disorder. NPJ MENTAL HEALTH RESEARCH 2023; 2:8.

Abstract
Borderline personality disorder (BPD) is characterized by patterns of unstable affect, unstable interpersonal relationships, and chronic suicidal tendencies. Research on the genetics, epigenetics, and brain function of BPD is lacking. MicroRNA-124-3p (miR-124-3p) was recently identified in a Genome-Wide Association Study as likely associated with BPD. Here, we identified the anatomical brain expression of genes likely modulated by miR-124-3p and compared morphometry in those brain regions in BPD inpatients vs. controls matched for psychiatric comorbidities. We isolated lists of targets likely modulated by miR-124-3p from TargetScan (v 8.0) by their preferentially conserved targeting (Aggregate PCT > 0.99, see Supplementary Table 1). We applied Process Genes List (PGL) to identify regions of interest associated with the co-expression of miR-124-3p target genes. We compared the gray matter volume of the top region of interest co-expressing those genes between BPD inpatients (n = 111, 46% female) and psychiatric controls (n = 111, 54% female) at The Menninger Clinic in Houston, Texas. We then correlated personality measures, suicidal ideation intensity, and recovery from suicidal ideation with volumetrics. Gene targets of miR-124-3p were significantly co-expressed in the left Globus Pallidus (GP), which was smaller in BPD than in psychiatric controls. Smaller GP volume was negatively correlated with agreeableness and with recovery from suicidal ideation post-treatment. In BPD, GP volume may be reduced through miR-124-3p regulation and suppression of its target genes. Importantly, we identified that a reduction of the GP in BPD could serve as a potential biomarker for recovery from suicidal ideation.

Abstract
Cluster B personality disorders (PDs) share specific traits that can result in interpersonal conflict. As therapeutic working alliance has a strong relationship with improved outcomes, there is interest in understanding the relationship between PDs, working alliance, and clinical outcomes. This is especially compelling in inpatient populations, where symptoms are severe, and patients are working with a treatment team. The aims of this study were to (a) assess whether higher team working alliance is associated with lower depressive symptoms, (b) assess whether patients with Cluster B PD traits have worse working alliance with their team than patients without those Cluster B PD traits, and (c) assess whether higher team working alliance is associated with lower depressive symptoms when Cluster B PD traits are present. Team working alliance was measured at baseline and at discharge for 3,406 inpatients at a psychiatric hospital. Improved team working alliance was associated with lower depression scores at discharge. Patients with borderline personality disorder traits had worse team working alliance, whereas patients with narcissistic personality disorder and antisocial personality disorder traits had similar working alliance scores as other patients. Borderline personality disorder and antisocial personality disorder traits moderated the association between team working alliance and depressive symptoms differently. Findings suggest that team working alliance works similarly to therapist working alliance. Of clinical importance is the finding that team working alliance and its relationship with depression symptoms differ based on Cluster B PD traits, and the importance of strong working alliance regardless of interpersonal challenges due to personality pathology.

Abstract
As sleep problems have been identified as an important, yet understudied, predictor of suicide risk, the present study analyzed the relationship between daytime sleepiness and nighttime sleep disturbance in a high-risk population of adults admitted to an inpatient psychiatric hospital. Objectives were to (1) examine the time course of subjective daytime sleepiness, nighttime sleep disturbance, and suicide risk throughout inpatient psychiatric treatment, (2) examine pre- to post-treatment changes in sleep disturbance with treatment as usual in an inpatient psychiatric setting, and (3) investigate whether daytime sleepiness and nighttime sleep disturbance predicted suicide risk above and beyond anxiety and depression. Participants were 500 consecutively admitted adults admitted to an intermediate length of stay (4-6 weeks) inpatient psychiatric hospital (47% female; 18-87 years of age). Measures of sleep, suicide risk, depression, and anxiety were completed at admission, weeks 1 through 4, and at discharge. Latent growth curve modeling (LGM) and hierarchal linear modeling (HLM) were conducted. The LGM analysis demonstrated that daytime sleepiness, nighttime sleep disturbance, and suicide risk all improved throughout inpatient treatment. Further, HLM showed that daytime sleepiness predicted suicide risk above and beyond symptoms of anxiety, depression, major sleep medications, and prior suicidal ideation and attempts, while nighttime sleep disturbance predicted suicide risk above and beyond symptoms of anxiety, major sleep medications, and prior suicidal ideation and attempts. Findings indicate the need to reevaluate safety protocols that may impact sleep, particularly that may increase daytime sleepiness, and to develop evidence-based sleep interventions for individuals admitted to inpatient psychiatric hospitals.

Abstract
While the negative effects of Coronavirus Disease-2019 (COVID-19) on general mental health are well-established, less is known about the impact on those with severe mental illness. Thus, this study examined symptom severity among psychiatric inpatients admitted prior to versus during the COVID pandemic. Self-reported anxiety (GAD-7), depression (PHQ-9), emotional dysregulation (DERS-SF), sleep quality (PSQI), nightmares (DDNSI), and suicidal ideation (SBQ-R) were examined in 470 adults (n = 235 admitted pre-pandemic) and 142 children and adolescents (n = 65 admitted pre-pandemic) at admission. Adults also completed measures of disability (WHODAS) and substance use (WHOASSIST). Adults admitted during the COVID pandemic reported significantly higher levels of anxiety [p < .001, partial η2=0.18], depression [p < .001, partial η2=0.06], emotion dysregulation [p < .001, partial η2=0.05], nightmares [p = .013, partial η2=0.01], and disability [p < .001, partial η2=0.04] compared to adults admitted pre-COVID. Levels of anxiety [p = .005, partial η2=0.05], depression [p = .005, partial η2=0.06], and sleep quality [p = .011, partial η2=0.05] were significantly higher among adolescents admitted during COVID compared to pre-COVID. The findings help identify areas of prioritization for future mental health prevention/intervention efforts for future disease outbreaks.

Abstract
Emerging adulthood is a critical developmental period characterized by emotional growth and unstructured living. To date, there is little research on emerging adults-defined as those 18 to 25 years old-with serious mental illnesses and even less on emerging adults in psychiatric hospitals. This study analyzed therapeutic alliance with the clinical team and change in anxiety symptoms in emerging adult psychiatric inpatients with the goal of establishing whether emotion regulation could serve as a mediator between these 2 constructs. Participants were 913 emerging adults (46.7% female; 18 to 25 y of age) who were voluntarily admitted to an intermediate length-of-stay (6 to 8 wk) inpatient psychiatric hospital. Each patient completed measures assessing anxiety symptoms, emotion regulation strategies, and working alliance as an assessment of therapeutic alliance. The results indicated that working alliance had significant indirect effects on change in anxiety symptoms through emotion dysregulation and lack of awareness, limited access to emotion regulation strategies, and lack of emotional clarity. This study emphasizes the need to understand emerging adults and the difficulties characteristic of this developmental period, and that clinicians should be aware that cognitive factors involved in emotion regulation may impact anxiety symptoms in emerging adult populations.

Abstract
Digital transformation is the adoption of digital technologies by an entity in an effort to increase operational efficiency. In mental health care, digital transformation entails technology implementation to improve the quality of care and mental health outcomes. Most psychiatric hospitals rely heavily on "high-touch" interventions or those that require in-person, face-to-face interaction with the patient. Those that are exploring digital mental health care interventions, particularly for outpatient care, often copiously commit to the "high-tech" model, losing the crucial human element. The process of digital transformation, especially within acute psychiatric treatment settings, is in its infancy. Existing implementation models outline the development of patient-facing treatment interventions within the primary care system; however, to our knowledge, there is no proposed or established model for implementing a new provider-facing ministration tool within an acute inpatient psychiatric setting. Solving the complex challenges within mental health care demands that new mental health technology is developed in concert with a use protocol by and for the inpatient mental health professional (IMHP; the end user), allowing the "high-touch" to inform the "high-tech" and vice versa. Therefore, in this viewpoint article, we propose the Technology Implementation for Mental-Health End-Users framework, which outlines the process for developing a prototype of an IMHP-facing digital intervention tool in parallel with a protocol for the IMHP end user to deliver the intervention. By balancing the design of the digital mental health care intervention tool with IMHP end user resource development, we can significantly improve mental health outcomes and pioneer digital transformation nationwide.

Abstract
OBJECTIVE Postdischarge from inpatient psychiatry is the highest risk period for suicide, thus better understanding the predictors of death by suicide during this time is critical for improving mortality rates after inpatient psychiatric treatment. As such, we sought to determine whether there were predictable patterns in suicide ideation in hospitalized psychiatric patients. METHOD We examined a sample of 2,970 adult's ages 18-87 admitted to an extended length of stay (LOS) inpatient psychiatric hospital. We used group-based trajectory modeling via the SAS macro PROC TRAJ to quantitatively determine four suicide ideation groups: nonresponders (i.e., high suicide ideation throughout treatment), responders (i.e., steady improvement in suicide ideation across treatment), resolvers (i.e., rapid improvement in suicide ideation across treatment), and no-suicide ideation (i.e., never significant suicide ideation in treatment). Next, we compared groups to clinical and suicide-specific outcomes, including death by suicide. RESULTS Resolvers were the most likely to die by suicide postdischarge relative to all other suicide ideation groups. Resolvers also demonstrated significant improvement in all clinical outcomes from admission to discharge. CONCLUSION There are essential inpatient psychiatry clinical implications from this work, including that clinical providers should not be lulled into a false sense of security when hospitalized adults rapidly improve in terms of suicide ideation. Instead, inpatient psychiatric treatment teams should increase caution regarding the patient's risk level and postdischarge treatment planning.

Abstract
The impact of COVID-19 changed the use and delivery of health care services, requiring an abrupt shift in treatment and staffing models 1,2. This is particularly salient in youth acute and intensive treatment services (AITS), including inpatient psychiatric hospitals (IPH), intensive outpatient programs (IOP), and partial hospitalization programs (PHP), because of challenging issues of maintaining high-quality care and a safe therapeutic milieu during increased demand for acute services,3 all while limiting transmission of COVID-19 on locked units, in close quarters, and for youths traveling back and forth to day-programs. Over the past year, AITS adapted and evolved without the ability to pause services and plan, increase staffing, or allocate additional resources. This article discusses themes of changes made based on more than 20 facilities across the United States through the American Psychological Association Child and Adolescent Psychology Division's Acute, Intensive, and Residential Service Special Interest Group.4 These facilities include psychiatric inpatient units and day-treatment programs. We discuss lessons learned from these changes, the need for evaluating these changes, and application of these lessons in future crises.

Sleep disturbance in patients in an inpatient hospital mediates relationship between PTSD and suicidal ideation. J Psychiatr Res 2021; 133:174-180.

Abstract
A common reason for admission to inpatient psychiatric units is suicidal ideation. Growing evidence of the link between sleep disturbance and suicidal ideation brings an interest in greater clarity of the pathways; this paper focused on post-traumatic stress disorder (PTSD), which carries increased risk for both sleep disturbance and suicidal ideation, as well as sex differences in those pathways. Patients were 2822 inpatients studied at admission to an inpatient psychiatric hospital and mediation analyses were used to examine pathways of interest. There was an indirect effect of PTSD on suicidal ideation through sleep disturbances for the entire sample and for men and women separately. The effect for men was larger than that for women, suggesting a stronger effect for sleep disturbance in the relationship for men. For women only, the direct effect between PTSD and suicidal ideation remained significant after mediation. Sleep disturbance plays an important role in the relationship between PTSD and suicidal ideation. Early identification of sleep disturbance in inpatients and targeted focus of sleep in conjunction with resolving trauma-related symptoms may help reduce suicidal ideation. This may be especially true of men; the indirect effect was smaller for women, suggesting that sleep disturbance should be addressed in conjunction with other PTSD symptoms likely leading to suicidal ideation.

Abstract
Early discharge or reduced length of stay for inpatient psychiatric patients is related to increased readmission rates and worse clinical outcomes including increased risk for suicide. Trajectories of mental illness outcomes have been identified as an important method for predicting the optimal length of stay but the distinguishing factors that separate trajectories remain unclear. We sought to identify the distinct classes of patients who demonstrated similar trajectories of mental illness over the course of inpatient treatment, and we explore the patient characteristics associated with these mental illness trajectories. We used data (N = 3406) from an inpatient psychiatric hospital with intermediate lengths of stay. Using growth mixture modeling, latent mental illness scores were derived from six mental illness indicators: psychological flexibility, emotion regulation problems, anxiety, depression, suicidal ideation, and disability. The patients were grouped into three distinct trajectory classes: (1) High-Risk, Rapid Improvement (HR-RI); (2) Low-Risk, Gradual Improvement (LR-GI); and (3) High-Risk, Gradual Improvement (HR-GI). The HR-GI was significantly younger than the other two classes. The HR-GI had significantly more female patients than males, while the LR-GI had more male patients than females. Our findings indicated that younger females had more severe mental illness at admission and only gradual improvement during the inpatient treatment period, and they remained in treatment for longer lengths of stay, than older males.

Association of TPH1 and serotonin transporter genotypes with treatment response for suicidal ideation: a preliminary study. Eur Arch Psychiatry Clin Neurosci 2020; 270:633-642.

Abstract
Variants in three genes coding for components of the serotonergic system, the tryptophan hydroxylase 1 (TPH1) rs1799913, serotonin transporter (SLC6A4) 5-HTTLPR, and serotonin receptor 2A (HTR2A) rs6311, were evaluated for association with suicidal ideation (SI) and with recovery from SI in a psychiatric inpatient population. Five hundred and eighty-two adult inpatients, including 390 patients who had SI, collected from December 2012 to April 2016 were assessed. SI recovery, calculated as change in SI between the first two-week period after admission and weeks 5 and 6, was appraised for association with the three variants. In this preliminary study, both TPH1 and 5-HTTLPR genotypes were associated with recovery (TPH1: recessive model, increased recovery with AC genotype, P = 0.026; additive model, increased recovery with AC genotype, P = 0.037; 5-HTTLPR: recessive model, increased recovery with AC, P = 0.043). When patients with comorbid alcohol use disorder (AUD) were removed, given that TPH1 has been associated with alcoholism, the associations of those recovered from SI with TPH1 rs1799913 remained significant for the additive (increased recovery with AC, P = 0.045) and recessive (increased recovery with C-carriers, P = 0.008) models, and with 5-HTTLPR using the dominant model (increased recovery with S'S', P = 0.016). In females, an association of SI recovery with TPH1 rs1799913 was found using a recessive model (increased recovery with C-carriers, P = 0.031), with 5-HTTLPR using additive (increased recovery with L'S', P = 0.048) and recessive (increased recovery with S'S', P = 0.042) models. Additionally, an association of SI with TPH1 rs1799913 was found in females using both additive (increased risk in AC, P = 0.033) and recessive (increased risk in C-carriers, P = 0.043) models, and with 5-HTTLPR using a recessive model (increased risk in S'S', P = 0.030). This study provides evidence that variation in the TPH1 and serotonin transporter genes play key roles in moderating recovery from SI during treatment in an inpatient psychiatric clinic.

Objective measurement of sleep, heart rate, heart rate variability, and physical activity in suicidality: A systematic review. J Affect Disord 2020; 273:318-327. [PMID: 32421619 PMCID: PMC7306422 DOI: 10.1016/j.jad.2020.03.096] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2019] [Revised: 01/27/2020] [Accepted: 03/28/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND Emerging literature suggests that the arousal and regulatory systems as measured by sleep-wakefulness, heart rate (HR) and heart rate variability (HRV) may be powerful objective warning signs of suicidality. However, there is no systematic literature review examining the association between objective measurements of these variables with suicide and suicidal behavior. METHODS A web-based, systematic literature search using PubMed and EMBASE was conducted for articles that measured sleep-wakefulness and HR/HRV quantitatively in association with suicide. Search results were limited to human subjects and articles published in peer-reviewed journals in English. There were no restrictions for age, sex, settings and durations of measurements, types of mental illnesses, or comorbidity. RESULTS Twenty-three studies were included in the current systematic review. Across the studies, consistent patterns of disturbed sleep-wakefulness such as greater sleep onset latency and lower sleep efficiency were related to suicide. In addition, higher HR and lower variance of R-R intervals was an indicator of risk of suicide. LIMITATIONS Studies that used different equipment for sleep studies (i.e., polysomnography, electroencephalogram, actigraphy) were combined, and potential differences in their findings due to the different equipment were not considered. CONCLUSIONS Findings provide initial evidence for consistent patterns of sleep-wakefulness and HR/HRV possibly associated with suicidality; however, more studies are needed in order to identify the precise objective variables (e.g., sleep onset latency, high-frequency HRV), as well as time-varying patterns in these variables, that are related to acute suicide risk.

Abstract
BACKGROUND Linking human genetics and brain imaging data is extremely challenging, among other reasons because both fields suffer from multiple comparison problems. NEW METHOD ProcessGeneLists (PGL) links genetics and human brain imaging by using genes associated with a disease and calculating a normalized mRNA expression average of those genes in each brain region. Brain regions in which those genes are most co-expressed become regions of interest (ROIs) to perform brain imaging in participants with and without the disease, decreasing multiple comparisons. Once a region is identified as "imaging-relevant", the genes most responsible for that ROI being highlighted can be genotyped in the imaged sample. This allows to re-analyze imaging data under the light of likely relevant genetics, to study possible brain imaging/gene variant interactions. RESULTS As proof-of-concept, we created two lists of genes expressed in the habenula and the striatum, to verified that PGL would highlight those regions. Next, we used a list of genes likely important in alcohol abuse from the literature, which identified several brain regions previously associated with alcohol abuse such as the striatum, habenula, and hippocampus. COMPARISON WITH EXISTING METHODS To our knowledge there is no current method to obtain brain regions of interest from genetics data. CONCLUSIONS Genetics typically asks "which genes are associated with a disease?" while human brain imaging typically asks "which brain regions are associated with a disease?" PGL asks "which genes, via modulation within specific brain regions, are found to be associated with a disease?".

Abstract
BACKGROUND As there has been a demonstrated link between sleep disturbance and suicide, the present study investigated the relationship between self-reported sleep disturbance during inpatient psychiatric treatment and clinical outcomes at discharge and six months post-discharge. METHODS Participants were 2,970 adults receiving care in a long-term inpatient psychiatric hospital. Greater than 90% of inpatients reported at least mild sleep disturbance throughout treatment. Group-based trajectory modeling was used to determine patterns of sleep disturbance changes over time. RESULTS Participants fit into distinct categories based on their trajectories of sleep problems across treatment: No Sleep Problems (10.3% of participants, no sleep problems endorsed over the course of inpatient psychiatric treatment), Resolvers (sleep problems completely resolved over the course of inpatient psychiatric treatment; 10.6%), Non-Responders (did not respond to inpatient psychiatric treatment; 35.7%) and Responders (sleep problems decreased but did not fully resolve over the course of inpatient psychiatric treatment; 43.4%). Individuals with comorbid major depressive disorder and generalized anxiety disorder were significantly more likely to demonstrate higher rates of sleep disturbance throughout inpatient psychiatric treatment and their sleep problems did not respond to treatment as usual (Non-Responders). Further, patients in the Non-Responder group had significantly more suicidal ideation and worse clinical outcomes (higher anxiety, more disability, and lower well-being) at discharge and six months post-discharge, as well as were on more medication including hypnotics throughout treatment. CONCLUSIONS Findings indicate the urgent need to design and implement inpatient psychiatry sleep protocols to not only improve sleep and clinical outcomes, but also reduce the risk for suicide post-discharge.

Abstract
Serious mental illness (SMI) is disabling, and current interventions are ineffective for many. This exploratory study sought to demonstrate the feasibility of applying topological data analysis (TDA) to resting-state functional connectivity data obtained from a heterogeneous sample of 235 adult inpatients to identify a biomarker of treatment response. TDA identified two groups based on connectivity between the prefrontal cortex and striatal regions: patients admitted with greater functional connectivity between these regions evidenced less improvement from admission to discharge than patients with lesser connectivity between them. TDA identified a potential biomarker of an attenuated treatment response among inpatients with SMI. Insofar as the observed pattern of resting-state functional connectivity collected early during treatment is replicable, this potential biomarker may indicate the need to modify standard of care for a small, albeit meaningful, percentage of patients.

Abstract
Social impairments in autism spectrum disorder (ASD), a hallmark feature of its diagnosis, may underlie specific neural signatures that can aid in differentiating between those with and without ASD. To assess common and consistent patterns of differences in brain responses underlying social cognition in ASD, this study applied an activation likelihood estimation (ALE) meta-analysis to results from 50 neuroimaging studies of social cognition in children and adults with ASD. In addition, the group ALE clusters of activation obtained from this was used as a social brain mask to perform surface-based cortical morphometry (SBM) in an empirical structural MRI dataset collected from 55 ASD and 60 typically developing (TD) control participants. Overall, the ALE meta-analysis revealed consistent differences in activation in the posterior superior temporal sulcus at the temporoparietal junction, middle frontal gyrus, fusiform face area (FFA), inferior frontal gyrus (IFG), amygdala, insula, and cingulate cortex between ASD and TD individuals. SBM analysis showed alterations in the thickness, volume, and surface area in individuals with ASD in STS, insula, and FFA. Increased cortical thickness was found in individuals with ASD, the IFG. The results of this study provide functional and anatomical bases of social cognition abnormalities in ASD by identifying common signatures from a large pool of neuroimaging studies. These findings provide new insights into the quest for a neuroimaging-based marker for ASD. Hum Brain Mapp 37:3957-3978, 2016. © 2016 Wiley Periodicals, Inc.

Abstract
OBJECTIVE This study investigated variants of tryptophan hydroxylase (TPH)1, TPH2, and SLC6A4 in the moderation of the subjective effects of cocaine. METHODS Non-treatment-seeking cocaine-dependent individuals (N=66) were intravenously administered saline and cocaine (40 mg) in a randomized order. Participants self-reported subjective effects of cocaine using a visual analog scale starting before administration of saline or cocaine (-15 min) to up to 20 min after infusion. Self-report ratings on the visual analog scale ranged from 0 (no effect) to 100 (greatest effect). Participants were genotyped for the TPH1 rs1799913, TPH2 rs4290270, and SLC6A4 5-HTTLPR variants. Repeated-measures analysis of covariance was used to examine changes in subjective effect scores over time while controlling for population structure. RESULTS Participants carrying the TPH1 rs1799913 A allele reported greater subjective response to cocaine for 'stimulated' and 'access' relative to the CC genotype group. Those carrying the TPH2 rs4290270 A allele reported higher 'good effect' and lower 'depressed' effect relative to the TT genotype group. Those carrying the SLC6A4 5-HTTLPR S' allele reported greater 'desire' and 'access' compared with the L'L' genotype group. CONCLUSION These findings indicate that TPH1, TPH2, and SLC6A4 variants moderate the subjective effects of cocaine in non-treatment-seeking cocaine-dependent participants.

Abstract
OBJECTIVE Distinguishing depressive episodes due to bipolar disorder (BD) or major depressive disorder (MDD) solely on clinical grounds is challenging. We aimed at comparing resting-state functional connectivity (rsFC) of regions subserving emotional regulation in similarly depressed BD and MDD. METHOD We enrolled 76 in-patients (BD, n = 36; MDD, n = 40) and 40 healthy controls (HC). A seed-based approach was used to identify regions showing different rsFC with the insula and the amygdala. Insular and amygdalar parcellations were then performed along with diagnostic accuracy of the main findings. RESULTS Lower rsFC between the left insula and the left mid-dorsolateral prefrontal cortex and between bilateral insula and right frontopolar prefrontal cortex (FPPFC) was observed in BD compared to MDD and HC. These results were driven by the dorsal anterior and posterior insula (PI). Lower rsFC between the right amygdala and the left anterior hippocampus was observed in MDD compared to BD and HC. These results were driven by the centromedial and laterobasal amygdala. Left PI/right FPPC rsFC showed 78% accuracy differentiating BD and MDD. CONCLUSION rsFC of amygdala and insula distinguished between depressed BD and MDD. The observed differences suggest the possibility of differential pathophysiological mechanisms of emotional dysfunction in bipolar and unipolar depression.

Abstract
BACKGROUND This study assessed the incremental validity of the Personality Inventory for DSM-5 (PID-5) beyond the impact of demographic, burden of illness, five-factor model of personality, and DSM-5 personality disorder criteria with respect to associations with admission psychiatric symptoms and functional disability. METHODS Psychiatric inpatients (N = 927) were administered the Big Five Inventory, PID-5, and personality disorder criteria counts. Prior treatment utilization, as well as baseline depression, anxiety, emotion regulation, and functional disability were administered within two days of the personality measures. Hierarchical regression models were used to explore the association of personality functioning with symptom functioning, emotion regulation and disability. RESULTS Neuroticism was associated with all symptom measures, providing further support for its relevance in clinical populations. Personality trait domains (negative affect, detachment, and psychoticism) from the PID-5 demonstrated incremental validity in predicting baseline symptom and disability functioning over and above demographic, burden of illness, and psychiatric comorbidity and five-factor model (FFM) personality traits. CONCLUSIONS Dimensional measures of personality functioning were consistently associated with baseline symptom functioning, supporting the relevance of personality functioning as it relates to psychiatric symptoms. The PID-5 uniquely contributed to the prediction of baseline symptom functioning, thus providing incremental validity over gold-standard personality trait measures.

Abstract
Two classification systems are now at the forefront of clinical psychiatric research: (1) Diagnostic and Statistical Manual, Fifth Edition and (2) the National Institutes of Mental Health Research Domain Criteria. Herein, we propose that these two classification systems are complementary rather than mutually exclusive, and when combined provide important information for understanding aspects of the pathophysiology related to Generalized Anxiety Disorder (GAD). The neurobiological literature for GAD and one relevant research domain criteria component, sustained threat, are reviewed from multiple units of analysis (genetic, neuroimaging, neuroendocrine, and psychophysiological). It is hypothesized that generating a comprehensive, biologically based understanding of the relationship between GAD, sustained threat, and the measureable units of analysis will provide information critical to design the most effective treatments.

Abstract
Exome sequencing and copy number variation analyses continue to provide novel insight to the biological bases of autism spectrum disorder (ASD). The growing speed at which massive genetic data are produced causes serious lags in analysis and interpretation of the data. Thus, there is a need to develop systematic genetic data mining processes that facilitate efficient analysis of large datasets. We report a new genetic data mining system, ProcessGeneLists and integrated a list of ASD-related genes with currently available resources in gene expression and functional connectivity of the human brain. Our data-mining program successfully identified three primary regions of interest (ROIs) in the mouse brain: inferior colliculus, ventral posterior complex of the thalamus (VPC), and parafascicular nucleus (PFn). To understand its pathogenic relevance in ASD, we examined the resting state functional connectivity (RSFC) of the homologous ROIs in human brain with other brain regions that were previously implicated in the neuro-psychiatric features of ASD. Among them, the RSFC of the VPC with the medial frontal gyrus (MFG) was significantly more anticorrelated, whereas the RSFC of the PN with the globus pallidus was significantly increased in children with ASD compared with healthy children. Moreover, greater values of RSFC between VPC and MFG were correlated with severity index and repetitive behaviors in children with ASD. No significant RSFC differences were detected in adults with ASD. Together, these data demonstrate the utility of our data-mining program through identifying the aberrant connectivity of thalamo-cortical circuits in children with ASD.

Abstract
Substance use disorders have significant personal, familial, and societal consequences. Despite the serious consequences of substance use, only a few therapies are effective in treating substance use disorders, thus highlighting a need for improved treatment practices. Substance use treatment response depends on multiple factors such as genetic, biological, and social factors. It is essential that each component is represented in treatment plans. The dopaminergic system plays a critical role in the pharmacotherapy for addictions, and an understanding of the role of variation of genes involved in this system is essential for its success. This review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guidelines. A computerized literature search was conducted using PubMed and Scopus (all databases). Articles published up to April 2015 that examined the role of dopaminergic gene variation in the pharmacotherapy of alcohol, opioid, and cocaine use disorders were reviewed. Search terms were dopamine, gene, polymorphism, substance abuse, treatment, and response. Polymorphisms of the DRD2, ANKK1, DAT1, DBH, and DRD4 genes have been found to moderate the effects of pharmacotherapy of alcohol, opioid, and cocaine use disorders. The integration of genetic information with clinical data will inform health professionals of the most efficacious pharmacotherapeutic intervention for substance use disorders. More studies are needed to confirm and extend these findings.

Altered Medial Frontal and Superior Temporal Response to Implicit Processing of Emotions in Autism. Autism Res 2015; 9:55-66.

Abstract
Interpreting emotional expressions appropriately poses a challenge for individuals with autism spectrum disorder (ASD). In particular, difficulties with emotional processing in ASD are more pronounced in contexts where emotional expressions are subtle, automatic, and reflexive-that is, implicit. In contrast, explicit emotional processing, which requires the cognitive evaluation of an emotional experience, appears to be relatively intact in individuals with ASD. In the present study, we examined the brain activation and functional connectivity differences underlying explicit and implicit emotional processing in age- and IQ-matched adults with (n = 17) and without (n = 15) ASD. Results indicated: (1) significantly reduced levels of brain activation in participants with ASD in medial prefrontal cortex (MPFC) and superior temporal gyrus (STG) during implicit emotion processing; (2) significantly weaker functional connectivity in the ASD group in connections of the MPFC with the amygdala, temporal lobe, parietal lobe, and fusiform gyrus; (3) No group difference in performance accuracy or reaction time; and (4) Significant positive relationship between empathizing ability and STG activity in ASD but not in typically developing participants. These findings suggest that the neural mechanisms underlying implicit, but not explicit, emotion processing may be altered at multiple levels in individuals with ASD.

Abstract
The current study examined depression and physiological reactivity to a sexual threat task as longitudinal predictors of sexual revictimization in women with sexual victimization histories. The sample included 14 young adult women (M(age) = 19.15) who reported child sexual abuse. Heart rate and root mean square of the successive differences were measured at baseline and during the presentation of sexual victimization-related words during an Emotional Stroop task. Results indicated that women who reported a greater history of childhood sexual abuse and adult sexual victimization were at increased risk for sexual revictimization 6 months after initial data collection. Furthermore, even after accounting for their childhood and adult sexual victimization histories and depression symptoms, women who exhibited reduced, or blunted, physiological activity during the sexual victimization stimuli of the Stroop task were more likely to report sexual revictimization during the 6-month follow-up. The findings suggest that sexual victimization survivors may benefit from interventions that address physiological blunting and the recognition of sexual threat cues in their environment.

Broad implications for respiratory sinus arrhythmia development: associations with childhood symptoms of psychopathology in a community sample. Dev Psychobiol 2014; 57:120-30.

Abstract
Replicating the group-based developmental trajectory methodology from our prior study (Patriquin, Lorenzi, Scarpa, & Bell. 2014. Developmental Psychobiology, 56, 317-326), the current study examines the development of baseline respiratory sinus arrhythmia (RSA) across a new, larger cohort of typically developing children at 5, 10, 24, 36, and 48 months of age and examines the trajectory relationship with symptoms of childhood psychopathology. Group-based developmental trajectory modeling replicated our prior findings of a two-group model fit: a "High RSA" and "Low RSA" group. The "Low RSA" group, which demonstrated lower baseline RSA across all time points, had significantly more childhood problems at 48 months, namely increased withdrawal, aggressive behavior, pervasive developmental problems, and oppositional defiant problems. All participants for whom there were developmental or autism spectrum concerns (n = 6; based on maternal report at 48 months) were allocated to the Low RSA trajectory group. These results suggest that consistent developmental trajectories of RSA may point to protective factors (i.e., high RSA) against developing symptoms of childhood psychopathology.

Abstract
This study investigated the psychometric properties of the modified checklist for autism in toddlers (M-CHAT) in a diverse rural American low-socioeconomic status (SES) sample. Four hundred and forty-seven English (n = 335) and Spanish (n = 112) speaking caregivers completed the M-CHAT during their toddler's 18- or 24-month well visit in a Southwest Virginia pediatric clinic. The M-CHAT did not show acceptable internal consistency in groups with low maternal education or minority status. Caregivers reporting low maternal education and minority status were more likely to endorse items suggestive of autism. These results indicate that the M-CHAT may require modifications to be more internally consistent and accurate across ethnic and educational groups in rural areas with low levels of SES. Recommendations to increase the utility of the M-CHAT are discussed.

Abstract
The present longitudinal study examined relations between respiratory sinus arrhythmia (RSA) development and social responsiveness characteristics associated with autism spectrum disorders. Group-based developmental trajectory modeling was used to characterize RSA development patterns in 106 typically developing children across 5, 10, 24, 36, and 48 months of age. A two-group model fit of RSA development was found: a "typically" and "atypically" developing group. The typical group gradually increased in RSA across 5-48 months of age. The atypical group, however, increased in RSA from 5 to 24 months and demonstrated a plateau or "delay" in RSA development from 24 to 48 months. The atypical RSA development group also demonstrated more difficulties in parent-reported social responsiveness at 48 months. The results support current literature that identifies RSA as a marker of social functioning level.

Thought control strategies as mediators of trauma symptoms in young women with histories of child sexual abuse. Behav Res Ther 2009; 47:809-13.

Abstract
The current retrospective study examined thought control strategies, or cognitive techniques individuals use to deal with unpleasant thoughts following stressful events, as potential mediators of adjustment in young women with histories of child sexual abuse (CSA). In a sample of 76 undergraduate women who self-reported on abuse experiences, thought control strategies, and current trauma symptoms, several key findings emerged: (i) Greater severity of the CSA event was associated with greater reported use of worry and punishment strategies and less use of social control strategies; (ii) Increased use of worry and punishment strategies following the CSA event was associated with greater levels of trauma symptoms, while increased use of social control strategies following the CSA event was associated with lower levels of trauma symptoms; and (iii) Worry, punishment, and social control strategies served as mediators between CSA severity and trauma symptoms. The results suggest that thought control strategies, specifically increased worry and punishment, and decreased social control, play a vital role in understanding adjustment after CSA. Future research should examine the roles of these cognitive control strategies as possible avenues of intervention following CSA.
