ABSTRACT

OBJECTIVE: To identify factors associated with non-treatment with biologic and non-biologic disease modifying anti-rheumatic drugs (DMARDs) during the 12 months after initial inflammatory arthritis (IA) diagnosis. METHODS: We identified Veterans with incident IA diagnosed in 2007-2019. We assessed time to treatment with Kaplan-Meier curves. We identified associations between non-treatment and factors relating to patients, providers, and the health system with multivariate Generalized Estimation Equation (GEE) log-Poisson. Subgroup analyses included IA subtypes (rheumatoid arthritis [RA], psoriatic arthritis [PsA], and ankylosing spondylitis [AS]) and timeframes of the initial IA diagnosis (2007-11, 2012-15, and 2016-19). RESULTS: Of 18,318 study patients, 40.7 % did not receive treatment within 12 months after diagnosis. In all patients, factors associated with non-treatment included Black race (hazard ratio, 95 % confidence interval: 1.13, 1.08-1.19), Hispanic ethnicity (1.14, 1.07-1.22), Charlson Comorbidity Index ≥2, (1.15, 1.11-1.20), and opiate use (1.09, 1.05-1.13). Factors associated with higher frequency of DMARD treatment included married status (0.86, 0.81-0.91); erosion in joint imaging report (HR: 0.86, 0.81-0.91); female diagnosing provider (0.90, CI: 0.85-0.96), gender concordance between patient and provider (0.91, CI: 0.86-0.97), and diagnosing provider specialty of rheumatology (0.53, CI: 0.49-0.56). CONCLUSION: A high proportion of Veterans with IA were not treated with a biologic or non-biologic DMARD within one year after their initial diagnosis. A wide range of factors were associated with non-treatment of IA that may represent missed opportunities for improving the quality of care through early initiation of DMARDs.

ABSTRACT

The first experimental study of the low-temperature kinetics of the gas-phase reaction between NH2 and NO has been performed. A pulsed laser photolysis-laser-induced fluorescence technique was used to create and monitor the temporal decay of NH2 in the presence of NO. Measurements were carried out over the temperature range of 24-106 K, with the low temperatures achieved using a pulsed Laval nozzle expansion. The negative temperature dependence of the reaction rate coefficient observed at higher temperatures in the literature continues at these lower temperatures, with the rate coefficient reaching 3.5 × 10-10 cm3 molecule-1 s-1 at T = 26 K. Ab initio calculations of the potential energy surface were combined with rate theory calculations using the MESMER software package in order to calculate and predict rate coefficients and branching ratios over a wide range of temperatures, which are largely consistent with experimentally determined literature values. These theoretical calculations indicate that at the low temperatures investigated for this reaction, only one product channel producing N2 + H2O is important. The rate coefficients determined in this study were used in a gas-phase astrochemical model. Models were run over a range of physical conditions appropriate for cold to warm molecular clouds (10 to 30 K; 104 to 106 cm-3), resulting in only minor changes (<1%) to the abundances of NH2 and NO at steady state. Hence, despite the observed increase in the rate at low temperatures, this mechanism is not a dominant loss mechanism for either NH2 or NO under dark cloud conditions.

ABSTRACT

OBJECTIVES: Compulsory mental health care includes compulsory hospitalisation and outpatient commitment with medication treatment without consent. Uncertain evidence of the effects of compulsory care contributes to large geographical variations and a controversy on its use. Some argue that compulsion can rarely be justified and should be reduced to an absolute minimum, while others claim compulsion can more frequently be justified. The limited evidence base has contributed to variations in care that raise issues about the quality/appropriateness of care as well as ethical concerns. To address the question whether compulsory mental health care results in superior, worse or equivalent outcomes for patients, this project will utilise registry-based longitudinal data to examine the effect of compulsory inpatient and outpatient care on multiple outcomes, including suicide and overall mortality; emergency care/injuries; crime and victimisation; and participation in the labour force and welfare dependency. METHODS: By using the natural variation in health providers' preference for compulsory care as a source of quasi-randomisation we will estimate causal effects of compulsory care on short- and long-term trajectories. CONCLUSIONS: This project will provide valuable insights for service providers and policy makers in facilitating high quality clinical care pathways for a high risk population group.

ABSTRACT

The first experimental study of the low-temperature kinetics of the gas-phase reaction of NH2 with acetaldehyde (CH3CHO) has been performed. Experiments were carried out using laser-flash photolysis and laser-induced fluorescence spectroscopy to create and monitor the temporal decay of NH2 in the presence of CH3CHO. Low temperatures relevant to the interstellar medium were achieved using a pulsed Laval nozzle expansion. Rate coefficients were measured over the temperature and pressure range of 29-107 K and 1.4-28.2 × 1016 molecules per cm3, with the reaction exhibiting a negative temperature dependence and a positive pressure dependence. The yield of CH3CO from the reaction has also been determined at 67.1 and 35.0 K, by observing OH produced from the reaction of CH3CO with added O2. Ab initio calculations of the potential energy surface (PES) were combined with Rice-Rampsberger-Kessel-Marcus (RRKM) calculations to predict rate coefficients and branching ratios over a broad range of temperatures and pressures. The calculated rate coefficients were shown to be sensitive to the calculated density of states of the stationary points, which in turn are sensitive to the inclusion of hindered rotor potentials for several of the vibrational frequencies. The experimentally determined rate coefficients and yields have been used to fit the calculated PES, from which low-pressure limiting rate coefficients relevant to the ISM were determined. These have been included in a single-point dark cloud astrochemical model, in which the reaction is shown to be a potential source of gas-phase CH3CO radicals under dark cloud conditions.

ABSTRACT

In our article, "How much does that cost? Examining the economic costs of crime in North America attributable to people with psychopathic personality disorder" (Gatner et al., 2023, pp. 391-400), we estimated that psychopathic personality disorder (PPD) was associated with substantial crime costs, using a top-down approach of national costs in the United States and Canada. Verona and Joyner (2023) raised several concerns about our findings. Although we think some of their points help to map directions for future research, we disagree with others they raised related to the conceptualization of PPD, the problem of undetected crimes, and their concerns with putative national comparisons. We strongly welcome debate about the societal impacts of PPD in the hope that it spurs increased attention and innovation regarding the treatment and management of PPD.

ABSTRACT

BACKGROUND: The objective of this post-hoc analysis was to assess the efficacy and safety of upadacitinib in psoriatic arthritis (PsA) patients with axial involvement. METHODS: Post-hoc analysis of SELECT-PsA 1 and SELECT-PsA 2 in patients randomized to upadacitinib 15 mg (UPA15), placebo (switched to UPA15 at week 24), or adalimumab 40 mg (ADA; SELECT-PsA 1 only). Axial involvement was determined by investigator judgement (yes or no; based on the totality of available clinical information, such as duration and characteristics of back pain, age of onset, and previous lab investigations and imaging, if available) alone, or investigator judgement and patient-reported outcome (PRO)-based criteria (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] ≥ 4 and BASDAI Q2 ≥ 4). Efficacy outcomes that describe axial disease activity, including BASDAI endpoints, such as change from baseline in the overall BASDAI score or proportion of patients achieving BASDAI50 (≥ 50% improvement from baseline), as well as Ankylosing Spondylitis Disease Activity Score (ASDAS) endpoints, such as mean change from baseline in overall ASDAS or proportion of patients achieving ASDAS inactive disease or low disease activity, were evaluated at weeks 12, 24, and 56, with nominal P-values shown. Treatment-emergent adverse events (TEAEs) are summarized through week 56. RESULTS: 30.9% of patients in SELECT-PsA 1 and 35.7% in SELECT-PsA 2 had axial involvement by investigator judgement alone; 22.6% (SELECT-PsA 1) and 28.6% (SELECT-PsA 2) had axial involvement by investigator judgement and PRO-based criteria. Greater proportions of patients achieved BASDAI50 with UPA15 versus placebo using either criterion, and versus ADA using investigator judgement alone, at week 24 in SELECT-PsA 1 (investigator alone: UPA15, 59.0%, placebo, 26.9%, P < 0.0001, ADA, 44.1%, P = 0.015; investigator and PRO-based: UPA15, 60.4%, placebo, 29.3%, P < 0.0001, ADA, 47.1%, P = 0.074), with comparable findings in SELECT-PsA 2. Similar results were observed with UPA15 for additional BASDAI and ASDAS endpoints at weeks 12 and 24, with improvements maintained at week 56. Rates of TEAEs were generally similar across sub-groups irrespective of axial involvement status. CONCLUSIONS: PsA patients with axial involvement determined by predefined criteria showed greater BASDAI and ASDAS responses with UPA15 versus placebo, and numerically similar/greater responses versus ADA. Safety results were generally comparable between patients with or without axial involvement. TRIAL REGISTRATION: ClinicalTrials.gov: SELECT-PsA 1, NCT03104400; SELECT-PsA 2, NCT0310437.

ABSTRACT

The current prospective risk assessment study evaluated the application of the Chinese translation of the Historical-Clinical-Risk Management-20 Version 3 (HCR-20V3 ) in a sample of 152 offenders with mental disorders and civil psychiatric patients. The ratings of the presence and relevance of risk factors were compared, as well as summary risk ratings (SRRs), both across offenders and civil psychiatric patients, and across male and female sub-samples. Interrater reliability was consistently "excellent" for the presence and relevance of risk factors and for SRRs. Concurrent validity analyses indicated that HCR-20V3 was strongly correlated with Violence Risk Scale (from r = 0.53 to 0.71). The results of predictive validity analyses provided strong support for the bivariate associations between the main indices of HCR-20V3 and violence within 6 weeks, 7-24 weeks, and 6 months; SRRs added incrementally to both relevance and presence ratings across three follow-up lengths.

ABSTRACT

Assessing violence risk amongst forensic patients is a vital legal and clinical task. The field of violence risk assessment has developed considerably over the past two decades but remains primarily risk focused. Despite this, growing attention to and work on protective factors or strengths has occurred. In this prospective naturalistic study with repeated observer-rated measures of 27 forensic patients, we tested the role of three potentially important but understudied dynamic protective factors: hope, insight, and resilience, along with a history of criminality, in terms of their impact on violence. Main effects models indicated that higher hopelessness and past criminal convictions were predictive of violence acts; higher resilience was associated with lower violence. In interaction models, hopelessness remained predictive. Importantly, there were significant interactions between resilience and past criminal convictions, with higher levels of resilience leading to lower violence, most amongst those with criminal convictions, and between resilience and hopelessness related emotional distress, in that higher resilience at high levels of patient acknowledged emotional distress due to hopelessness led to lower violence. Findings indicate the importance of focusing on strengths or protective factors in the assessment of risk and treatment planning for forensic patients. Despite the small sample, the repeated measures design was feasible and informative.

ABSTRACT

Cost of illness research has established that mental disorders lead to significant social burden and massive financial costs. A significant gap exists for the economic burden of many personality disorders, including psychopathic personality disorder (PPD). In the current study, we used a top-down prevalence-based cost of illness approach to estimate bounded crime cost estimates of PPD in the United States and Canada. Three key model parameters (PPD prevalence, relative offending rate of individuals with PPD, and national costs of crime for each country) were informed by existing literature. Sensitivity analyses and Monte Carlo simulations were conducted to provide bounded and central tendency estimates of crime costs, respectively. The estimated PPD-related costs of crime ranged from $245.50 billion to $1,591.57 billion (simulated means = $512.83 to $964.23 billion) in the United States and $12.14 billion to $53.00 billion (simulated means = $25.33 to $32.10 billion) in Canada. These results suggest that PPD may be associated with a substantial economic burden as a result of crime in North America. Recommendations are discussed regarding the burden-treatment discrepancy for PPD, as the development of future effective treatment for the disorder may decrease its costly burden on health and justice systems.

ABSTRACT

Section III of the fifth iteration of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes an alternative model of personality disorder diagnosis that conceptualizes antisocial personality disorder as an interpersonal, rather than behavioral, construct. However, the diagnostic specifier for psychopathy has been met with recent controversy due to its conceptual and empirical overlap with triarchic boldness, which has been debated as a necessary and sufficient domain of psychopathy. This study examined the concurrent, convergent, and discriminant validity of the specifier using canonical correlation analysis in samples of undergraduate students (N = 224) and community adults with prior criminal involvement (N = 306). Findings highlight the specifier as a multidimensional construct with divergent associations across its three facets. There was limited validity evidence for two of the three facets, raising concerns regarding the clinical utility of the psychopathy specifier.

ABSTRACT

The rate constants of many reactions currently considered to be important in the atmospheric chemistry of mercury remain to be measured in the laboratory. Here we report the first experimental determination of the rate constant of the gas-phase reaction between the HgBr radical and ozone, for which a value at room temperature of k(HgBr + O3) = (7.5 ± 0.6) × 10-11 cm3 molecule s-1 (1σ) has been obtained. The rate constants of two reduction side reactions were concurrently determined: k(HgBr + O) = (5.3 ± 0.4) × 10-11 cm3 molecule s-1 and k(HgBrO + O) = (9.1 ± 0.6) × 10-11 cm3 molecule s-1. The value of k(HgBr + O3) is slightly lower than the collision number, confirming the absence of a significant energy barrier. Considering the abundance of ozone in the troposphere, our experimental rate constant supports recent modelling results suggesting that the main atmospheric fate of HgBr is reaction with ozone to form BrHgO.

ABSTRACT

INTRODUCTION: Low disease activity (LDA)/remission is the target of treatment in patients with psoriatic arthritis (PsA). We assessed the proportions of patients with PsA receiving upadacitinib who achieved LDA/remission over 1 year. METHODS: This was a post hoc analysis of the double-blind, placebo-controlled SELECT-PsA 1 (also adalimumab-controlled) and SELECT-PsA 2 trials. Treatment targets assessed included LDA/remission defined by Disease Activity in Psoriatic Arthritis (≤ 14/ ≤ 4) and Psoriatic Arthritis Disease Activity Scores (≤ 3.2/ ≤ 1.9), as well as minimal disease activity (MDA)/very low disease activity (VLDA) states (5/7 and 7/7 components, respectively, of MDA criteria). Targets were assessed at 24 and 56 weeks. For binary outcomes, non-responder imputation was used for missing data. Data from patients receiving upadacitinib 30 mg was not included in the analysis. RESULTS: Overall, 1386 patients were analyzed. Disease control (i.e., LDA/MDA) was achieved at 24 weeks in upadacitinib 15 mg-treated patients across both studies: LDA/MDA was achieved by 25-48% of patients receiving upadacitinib 15 mg versus 2-16% of patients receiving placebo, and remission/VLDA rates were 7-14% with upadacitinib 15 mg versus 0-4% with placebo. The proportions of patients achieving treatment targets were numerically similar to upadacitinib 15 mg and adalimumab. All responses were sustained at 56 weeks. CONCLUSIONS: Remission and LDA are feasible targets with upadacitinib treatment in patients with PsA. TRIAL REGISTRATION: ClinicalTrial.gov identifiers NCT03104400 (SELECT-PsA 1) and NCT03104374 (SELECT-PsA 2).


Psoriatic arthritis is a disease that causes inflammation of the skin and joints. Doctors measure how bad a patient's disease is by measuring signs and symptoms of the disease, and using these to make a "score." The aim of treatment is to reduce the score to low levels (known as "low disease activity") or very low levels ("remission"). This study looked at results from two clinical trials that compared upadacitinib, a medicine used to treat psoriatic arthritis, with no medicine (placebo) to see how many patients had low disease activity or were in remission after 1 year of treatment. The results showed that more patients who were taking upadacitinib had low disease activity or were in remission after the first 6 months of treatment compared with those who took placebo. This difference between upadacitinib and placebo could still be seen after 1 year of treatment. These results show that treatment with upadacitinib is effective enough for some patients with psoriatic arthritis to achieve low disease activity or remission and to stay at this level, even after more than 1 year of treatment.

ABSTRACT

OBJECTIVE: Despite advances in developing structured risk assessment instruments, there is currently no instrument to assess and manage the risk of intimate partner violence perpetration among adolescents. Given the empirical link between many forms of antisocial behavior, we tested whether structured tools commonly used by professionals to evaluate adolescents' risk of engaging in general violence and offending could be used to identify adolescents at risk for perpetrating intimate partner violence. HYPOTHESES: Because researchers have not yet examined whether risk assessment tools for general violence and offending predict intimate partner violence perpetration, we did not have a priori hypotheses regarding the predictive validity of these tools for this purpose. METHOD: Research assistants rated 156 adjudicated youth on the Structured Assessment of Violence Risk in Youth (SAVRY), Youth Level of Service/Case Management Inventory (YLS/CMI), and Psychopathy Checklist: Youth Version (PCL:YV) and recorded charges for intimate partner violence perpetration, any violent reoffending, and any reoffending over a 2-year follow-up period. RESULTS: Receiver operating characteristic analysis indicated that total scores and summary risk ratings on the SAVRY and YLS/CMI and total scores on the PCL:YV were significantly predictive of any violent reoffending and any reoffending, with moderate to large effect sizes, but were nonsignificantly associated with intimate partner violence perpetration. Further, penalized logistic regression analysis indicated that the SAVRY, YLS/CMI, and PCL:YV did not significantly add incremental validity to age, gender, race/ethnicity, and prior intimate partner violence perpetration and victimization for predicting future intimate partner violence perpetration. CONCLUSIONS: These findings suggest that the SAVRY, YLS/CMI, and PCL:YV could have limitations for assessing and managing intimate partner violence perpetration among adolescents.

ABSTRACT

The Comprehensive Assessment of Psychopathic Personality-Lexical Rating Scale (CAPP-LRS) is a self-report instrument designed to index psychopathy according to the CAPP psychopathy framework. Developed with the expressed goal of advancing the state of knowledge regarding the specific features of psychopathy, the CAPP model and associated instruments have garnered increasing attention and support in the field. Despite the conceptual strength of the CAPP model, the advanced lexical structure of its primary research tool (the CAPP-LRS) has led researchers to question the utility of the instrument for use with some populations of interest (e.g., forensic/correctional and adolescent/young adult samples). The aim of the present work was to address this issue by creating a lexically simplified, though functionally equivalent, version of the CAPP-LRS to increase accessibility to critically relevant populations. A set of two studies (N = 602) describes the adaptation protocol and the initial validation of the modified instrument.

ABSTRACT

Reports an error in "Examining the incremental and interactive effects of boldness with meanness and disinhibition within the triarchic model of psychopathy" by Dylan T. Gatner, Kevin S. Douglas and Stephen D. Hart (Personality Disorders: Theory, Research, and Treatment, 2016[Jul], Vol 7[3], 259-268). In the original article, there were several errors in the reporting of data from the Social Emotional Questionnaire. In the "Outcome Measures" section of the Method, under the "Social and emotional functioning" heading, the Sociability subscale was incorrectly identified as the Social Conformity scale. The sentence referencing the data should have read, "However, the Antisocial Behavior (α = .39, MIC = .14) and Sociability (α = -.09, MIC = .02) subscales had poor internal consistency; the Sociability subscale was removed from our analyses." In the last paragraph of the "Research Question 2: Incremental Value of Boldness" section in the Results, the data for the Sociability scale have been replaced with the data for the Social Conformity scale. Additionally, the data reported for the Sociability scale in Tables 2 and 3 have been replaced with the data reported for the Social Conformity scale. (The following abstract of the original article appeared in record 2016-13473-001). The triarchic model of psychopathy (Patrick, Fowles, & Krueger, 2009) comprises 3 phenotypic domains: Meanness, Disinhibition, and Boldness. Ongoing controversy surrounds the relevance of Boldness in the conceptualization and assessment of psychopathy. In the current study, undergraduate students (N = 439) completed the Triarchic Psychopathy Measure (Patrick, 2010) to examine the association between Boldness and a host of theoretically relevant external criteria. Boldness was generally unrelated to either prosocial or harmful criteria. Boldness rarely provided incremental value above or interacted with Meanness and Disinhibition with respect to external criteria. Curvilinear effects of Boldness rarely emerged. The findings suggest that Boldness might not be a central construct in the definition of psychopathic personality disorder. Implications for the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 2013) psychopathic specifier are discussed.

ABSTRACT

Genetic differences in cerebellar sensitivity to alcohol (EtOH) influence EtOH consumption phenotype in animal models and contribute to risk for developing an alcohol use disorder in humans. We previously determined that EtOH enhances cerebellar granule cell (GC) tonic GABAAR currents in low EtOH consuming rodent genotypes, but suppresses it in high EtOH consuming rodent genotypes. Moreover, pharmacologically counteracting EtOH suppression of GC tonic GABAAR currents reduces EtOH consumption in high alcohol consuming C57BL/6J (B6J) mice, suggesting a causative role. In the low EtOH consuming rodent models tested to date, EtOH enhancement of GC tonic GABAAR currents is mediated by inhibition of neuronal nitric oxide synthase (nNOS) which drives increased vesicular GABA release onto GCs and a consequent enhancement of tonic GABAAR currents. Consequently, genetic variation in nNOS expression across rodent genotypes is a key determinant of whether EtOH enhances or suppresses tonic GABAAR currents, and thus EtOH consumption. We used behavioral, electrophysiological, and immunocytochemical techniques to further explore the relationship between EtOH consumption and GC GABAAR current responses in C57BL/6N (B6N) mice. B6N mice consume significantly less EtOH and achieve significantly lower blood EtOH concentrations than B6J mice, an outcome not mediated by differences in taste. In voltage-clamped GCs, EtOH enhanced the GC tonic current in B6N mice but suppressed it in B6J mice. Immunohistochemical and electrophysiological studies revealed significantly higher nNOS expression and function in the GC layer of B6N mice compared to B6Js. Collectively, our data demonstrate that despite being genetically similar, B6N mice consume significantly less EtOH than B6J mice, a behavioral difference paralleled by increased cerebellar nNOS expression and opposite EtOH action on GC tonic GABAAR currents in each genotype.

ABSTRACT

The Comprehensive Assessment of Psychopathic Personality (CAPP) is a lexically based conceptual model of psychopathy. Despite widespread use in research settings, the Lexical Rating Scale for the CAPP (CAPP-LRS) requires an advanced reading level for completion. The present study is the first to evaluate the content validity of the CAPP-Basic, a lexically simplified version of the CAPP-LRS designed for use with individuals possessing lower verbal skills. Symptoms were rated by mental health professionals (N = 121). Findings were largely in line with results of previous studies, indicating good content validity of the CAPP-Basic at the domain and symptom level.

ABSTRACT

The research evidence is very strong for high recidivism rates of violence after discharge from forensic facilities. Big data research has found that a substantial proportion of the forensic population with relapse into violence has a psychosis diagnosis and a criminal record. However, more research on the association between psychotic symptoms and violence may inform and enhance risk assessment, prevention, and treatment. We conducted a prospective naturalistic study with a repeated measures design in a sample of 22 psychotic patients during follow-up after discharge from forensic mental health facilities. We had three aims: to test the predictive validity of three psychotic symptom scales for violence, to analyze main and interaction effects between psychotic symptoms and previous criminal conviction, and to explore the feasibility and potential benefit of the repeated measures design for prospective follow-up research. Interpreted within the limitation of the small sample size, the results were promising for all scales, particularly for adjusted effects without interaction. Two scales remained significant when their interaction with criminal conviction was adjusted. This indicates that risk judgment of psychotic patients with criminal conviction can be improved by adding measurement of fluctuations in psychotic symptoms. The repeated measures design was instrumental in this research.
