A Visualization and Radiation Treatment Plan Quality Scoring Method for Triage in a Population-Based Context.

Purpose: Our purpose was to develop a clinically intuitive and easily understandable scoring method using statistical metrics to visually determine the quality of a radiation treatment plan. Methods and Materials: Data from 111 patients with head and neck cancer were used to establish a percentile-based scoring system for treatment plan quality evaluation on both a plan-by-plan and objective-by-objective basis. The percentile scores for each clinical objective and the overall treatment plan score were then visualized using a daisy plot. To validate our scoring method, 6 physicians were recruited to assess 60 plans, each using a scoring table consisting of a 5-point Likert scale (with scores ≥3 considered passing). Spearman correlation analysis was conducted to assess the association between increasing treatment plan percentile rank and physician rating, with Likert scores of 1 and 2 representing clinically unacceptable plans, scores of 3 and 4 representing plans needing minor edits, and a score of 5 representing clinically acceptable plans. Receiver operating characteristic curve analysis was used to assess the scoring system's ability to quantify plan quality. Results: Of the 60 plans scored by the physicians, 8 were deemed as clinically acceptable; these plans had an 89.0th ± 14.5 percentile value using our scoring system. The plans needing minor edits or deemed unacceptable had more variation, with scores falling in the 62.6nd ± 25.1 percentile and 35.6th ± 25.7 percentile, respectively. The estimated Spearman correlation coefficient between the physician score and treatment plan percentile was 0.53 (P < .001), indicating a moderate but statistically significant correlation. Receiver operating characteristic curve analysis demonstrated discernment between acceptable and unacceptable plan quality, with an area under the curve of 0.76. Conclusions: Our scoring system correlates with physician ratings while providing intuitive visual feedback for identifying good treatment plan quality, thereby indicating its utility in the quality assurance process.

Does smoking cessation reduce other substance use, psychiatric symptoms, and pain symptoms? Results from an emulated hypothetical randomized trial of US veterans.

BACKGROUND: Quitting smoking may lead to improvement in substance use, psychiatric symptoms, and pain, especially among high-risk populations who are more likely to experience comorbid conditions. However, causal inferences regarding smoking cessation and its subsequent benefits have been limited. METHODS: We emulated a hypothetical open-label randomized control trial of smoking cessation using longitudinal observational data of HIV-positive and HIV-negative US veterans from 2003-2015 in the Veterans Aging Cohort Study. We followed individuals from the first time they self-reported current cigarette smoking (baseline). We categorized participants as quitters or non-quitters at the first follow-up visit (approximately 1 year after baseline). Using inverse probability weighting to adjust for confounding and selection bias, we estimated odds ratios for improvement of co-occurring conditions (unhealthy alcohol use, cannabis use, illicit opioid use, cocaine use, depressive symptoms, anxiety symptoms, and pain symptoms) at second follow-up (approximately 2 years after baseline) for those who quit smoking compared to those who did not, among individuals who had the condition at baseline. RESULTS: Of 4,165 eligible individuals (i.e., current smokers at baseline), 419 reported no current smoking and 2,330 reported current smoking at the first follow-up. Adjusted odds ratios (95% confidence intervals) for associations between quitting smoking and improvement of each condition at second follow-up were: 2.10 (1.01, 4.35) for unhealthy alcohol use, 1.75 (1.00, 3.06) for cannabis use, 1.10 (0.58, 2.08) for illicit opioid use, and 2.25 (1.20, 4.24) for cocaine use, 0.78 (0.44, 1.38) for depressive symptoms, 0.93 (0.58, 1.49) for anxiety symptoms, and 1.31 (0.84, 2.06) for pain symptoms. CONCLUSIONS: While a causal interpretation of our findings may not be warranted, we found evidence for decreased substance use among veterans who quit cigarette smoking but none for the resolution of psychiatric conditions or pain symptoms. Findings suggest the need for additional resources combined with smoking cessation to reduce psychiatric and pain symptoms for high-risk populations.

A multi-iron enzyme installs copper-binding oxazolone/thioamide pairs on a nontypeable Haemophilus influenzae virulence factor.

The multinuclear nonheme iron-dependent oxidases (MNIOs) are a rapidly growing family of enzymes involved in the biosynthesis of ribosomally synthesized, posttranslationally modified peptide natural products (RiPPs). Recently, a secreted virulence factor from nontypeable Haemophilus influenzae (NTHi) was found to be expressed from an operon, which we designate the hvf operon, that also encodes an MNIO. Here, we show by Mössbauer spectroscopy that the MNIO HvfB contains a triiron cofactor. We demonstrate that HvfB works together with HvfC [a RiPP recognition element (RRE)-containing partner protein] to perform six posttranslational modifications of cysteine residues on the virulence factor precursor peptide HvfA. Structural characterization by tandem mass spectrometry and NMR shows that these six cysteine residues are converted to oxazolone and thioamide pairs, similar to those found in the RiPP methanobactin. Like methanobactin, the mature virulence factor, which we name oxazolin, uses these modified residues to coordinate Cu(I) ions. Considering the necessity of oxazolin for host cell invasion by NTHi, these findings point to a key role for copper during NTHi infection. Furthermore, oxazolin and its biosynthetic pathway represent a potential therapeutic target for NTHi.

Radar for Europa Assessment and Sounding: Ocean to Near-Surface (REASON).

The Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) is a dual-frequency ice-penetrating radar (9 and 60 MHz) onboard the Europa Clipper mission. REASON is designed to probe Europa from exosphere to subsurface ocean, contributing the third dimension to observations of this enigmatic world. The hypotheses REASON will test are that (1) the ice shell of Europa hosts liquid water, (2) the ice shell overlies an ocean and is subject to tidal flexing, and (3) the exosphere, near-surface, ice shell, and ocean participate in material exchange essential to the habitability of this moon. REASON will investigate processes governing this material exchange by characterizing the distribution of putative non-ice material (e.g., brines, salts) in the subsurface, searching for an ice-ocean interface, characterizing the ice shell's global structure, and constraining the amplitude of Europa's radial tidal deformations. REASON will accomplish these science objectives using a combination of radar measurement techniques including altimetry, reflectometry, sounding, interferometry, plasma characterization, and ranging. Building on a rich heritage from Earth, the moon, and Mars, REASON will be the first ice-penetrating radar to explore the outer solar system. Because these radars are untested for the icy worlds in the outer solar system, a novel approach to measurement quality assessment was developed to represent uncertainties in key properties of Europa that affect REASON performance and ensure robustness across a range of plausible parameters suggested for the icy moon. REASON will shed light on a never-before-seen dimension of Europa and - in concert with other instruments on Europa Clipper - help to investigate whether Europa is a habitable world.

Defect-Driven Configurational Entropy in the High-Entropy Oxide Li1.5MO3-δ.

Layered lithiated oxides are promising materials for next generation Li-ion battery cathode materials; however, instability during cycling results in poor performance over time compared to the high capacities theoretically possible with these materials. Here we report the characterizations of a Li1.47Mn0.57Al0.13Fe0.095Co0.105Ni0.095O2.49 high-entropy layered oxide (HELO) with the Li2MO3 structure where M = Mn, Al, Fe, Co, and Ni. Using electron microscopy and X-ray spectroscopy, we identify a homogeneous Li2MO3 structure stabilized by the entropic contribution of oxygen vacancies. This defect-driven entropy would not be attainable in the LiMO2 structure sometimes observed in similar materials as a secondary phase owing to the presence of fewer O sites and a 3+ oxidation state for the metal site; instead, a Li2-γMO3-δ is produced. Beyond Li2MO3, this defect-driven entropy approach to stabilizing novel compositions and phases can be applied to a wide array of future cathode materials including spinel and rock salt structures.

Intravenous ketamine for emergency department treatment of suicidal ideation in a paediatric population: protocol for a double-blind, randomised, placebo-controlled, parallel-arm pilot trial (KSI study).

INTRODUCTION: Suicidal ideation (SI) is a common and severe cause of morbidity in adolescents. Patients frequently present to the emergency department (ED) for care, yet there is no acute therapeutic intervention for SI. A single dose of intravenous ketamine has demonstrated efficacy in rapidly reducing SI in adults; however, ketamine has not been studied in paediatrics. We aim to determine the feasibility of a trial of a single intravenous ketamine dose to reduce SI for patients in the paediatric ED. METHODS AND ANALYSIS: This will be a single-centre, double-blind, randomised, placebo-controlled, parallel-arm pilot trial of intravenous ketamine for ED treatment of SI in a paediatric population. INTERVENTION: one intravenous dose of 0.5 mg/kg of ketamine (max 50 mg), over 40 min. Placebo: one intravenous dose of 0.5 mL/kg (max 50 mL) of normal saline, over 40 min. Participants will be randomised in a 1:1 ratio. SI severity will be measured at baseline, 40 min, 80 min, 120 min, 24 hours and 7 days. We aim to recruit 20 participants. The primary feasibility outcome is the proportion of eligible patients who complete the study protocol. We will pilot three SI severity tools and explore the efficacy, safety and tolerability of the intervention. ETHICS AND DISSEMINATION: This study will be conducted according to Canadian Biomedical Research Tutorial, international standards of Good Clinical Practice and the Health Canada, Food and Drug Act, Part C, Division 5. The study documents have been approved by the CHEO Research Institute Research Ethics Board (CHEO REB (23/02E)). Participants must provide free and informed consent to participate. If incapable due to age, assenting participants with parental/legal guardian consent may participate. On completion, we will endeavour to present results at international conferences, and publish the results in a peer-reviewed journal. Participants will receive a results letter. TRIAL REGISTRATION NUMBER: NCT05468840.

Connectome-based Brain Marker Moderates the Relationship between Childhood Adversity and Transdiagnostic Psychopathology during Early Adolescence.

Importance: Identifying brain-based markers of resiliency that reliably predict who is and is not at elevated risk for developing psychopathology among children who experience adverse childhood experiences (ACEs) is important for improving our mechanistic understanding of these etiological links between child adversity and psychopathology and guiding precision medicine and prevention efforts for reducing psychiatric impact of ACEs. Objective: To examine associations between ACEs and transdiagnostic psychopathology during the transition from preadolescence to early adolescence and test whether these associations are moderated by a hypothesized resilience factor, a previously identified connectome variate (CV) that is associated with higher cognitive function and lower psychopathology. Design Setting and Participants: This study was conducted in a longitudinal design based on multicenter data from a community cohort of U.S. youth aged of 9-11 at baseline, who participated in the Adolescent Brain Cognitive Development (ABCD) study (N=7,382 at baseline and 6,813 at 2-year follow-up). Linear regression models and moderation analyses were used to characterize concurrent and prospective associations between lifetime ACEs and number of DSM-5 psychiatric disorders (indexing transdiagnostic psychopathology) and to determine if individual variations in these associations were moderated by the CV derived from resting-state fMRI at baseline. Main Outcomes and Measures: Cumulative number of current DSM-5 psychiatric disorders assessed using the computerized self-admin version Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) and lifetime ACEs assessed from child and parent reports at baseline (9-10 years) and 2-year-follow-up (11-12 years). Results: ACE total scores correlated positively with the cumulative number of current DSM-5 psychiatric disorders at both baseline (r =.258, p < .001) and 2-year follow-up (r =.257, p < .001). The baseline CV score moderated the ACE-disorder associations at baseline (B = -0.021, p < .001) and at 2-year follow-up (B = -0.018, p = .008), as well as the association between the changes in ACE and in the number of disorders from baseline to year 2 (B = -0.012, p = .045). Post-hoc analyses further showed that the moderation effect of CV on ACE-psychopathology associations was specific to the threat-related ACEs and to female youth. Conclusions and Relevance: These findings provide preliminary evidence for a connectome-based resiliency marker and suggest that functional connectivity strength in a broad system including frontal-parietal cortices and subcortical nuclei relevant to cognitive control may protect preadolescents who have experienced lifetime ACEs--especially females and those experiencing threat-related ACEs--from developing transdiagnostic psychopathology.

Variable and Large Losses of Diagnostic Biomarkers After Simulated Cosmic Radiation Exposure in Clay- and Carbonate-Rich Mars Analog Samples.

Mars has been exposed to ionizing radiation for several billion years, and as part of the search for life on the Red Planet, it is crucial to understand the impact of radiation on biosignature preservation. Several NASA and ESA missions are looking for evidence of ancient life in samples collected at depths shallow enough that they have been impacted by galactic cosmic rays (GCRs). In this study, we exposed a diverse set of Mars analog samples to 0.9 Megagray (MGy) of gamma radiation to mimic 15 million years of exposure on the Martian surface. We measured no significant impact of GCRs on the total organic carbon (TOC) and bulk stable C isotopes in samples with initial TOC concentration > 0.1 wt. %; however, diagnostic molecular biosignatures presented a wide range of degradation that didn't correlate to factors like mineralogy, TOC, water content, and surface area. Exposure dating suggests that the surface of Gale crater has been irradiated at more than five times our dose, yet using this relatively low dose and "best-case scenario" geologically recalcitrant biomarkers, large and variable losses were nevertheless evident. Our results empasize the importance of selecting sampling sites at depth or recently exposed at the Martian surface.

Effects of cannabidiol, with and without ∆9-tetrahydrocannabinol, on anxiety-like behavior following alcohol withdrawal in mice.

Introduction: Alcohol use disorder (AUD) is commonly associated with anxiety disorders and enhanced stress-sensitivity; symptoms that can worsen during withdrawal to perpetuate continued alcohol use. Alcohol increases neuroimmune activity in the brain. Our recent evidence indicates that alcohol directly modulates neuroimmune function in the central amygdala (CeA), a key brain region regulating anxiety and alcohol intake, to alter neurotransmitter signaling. We hypothesized that cannabinoids, such as cannabidiol (CBD) and ∆9-tetrahydrocannabinol (THC), which are thought to reduce neuroinflammation and anxiety, may have potential utility to alleviate alcohol withdrawal-induced stress-sensitivity and anxiety-like behaviors via modulation of CeA neuroimmune function. Methods: We tested the effects of CBD and CBD:THC (3:1 ratio) on anxiety-like behaviors and neuroimmune function in the CeA of mice undergoing acute (4-h) and short-term (24-h) withdrawal from chronic intermittent alcohol vapor exposure (CIE). We further examined the impact of CBD and CBD:THC on alcohol withdrawal behaviors in the presence of an additional stressor. Results: We found that CBD and 3:1 CBD:THC increased anxiety-like behaviors at 4-h withdrawal. At 24-h withdrawal, CBD alone reduced anxiety-like behaviors while CBD:THC had mixed effects, showing increased center time indicating reduced anxiety-like behaviors, but increased immobility time that may indicate increased anxiety-like behaviors. These mixed effects may be due to altered metabolism of CBD and THC during alcohol withdrawal. Immunohistochemical analysis showed decreased S100ß and Iba1 cell counts in the CeA at 4-h withdrawal, but not at 24-h withdrawal, with CBD and CBD:THC reversing alcohol withdrawal effects.. Discussion: These results suggest that the use of cannabinoids during alcohol withdrawal may lead to exacerbated anxiety depending on timing of use, which may be related to neuroimmune cell function in the CeA.

Examining Identity Functioning in Anorexia Nervosa Across Illness and Recovery Stages.

OBJECTIVE: Research suggests that identity functioning (i.e., sense of self) issues may be a core feature of anorexia nervosa (AN). We aimed to investigate differences in identity functioning among women with AN at varying illness and recovery stages, and women with no history of eating disorders (non-ED controls). It was hypothesized that those with current AN (AN-C), weight-restored (AN-WR), and partial recovered individuals (AN-PR) would show poorer identity functioning than fully recovered individuals (AN-FR) and non-ED controls. METHOD: Women (334) with AN-C (n = 74), AN-WR (n = 90), AN-PR (n = 19), AN-FR (n = 22), and non-ED controls (n = 129) completed online self-report measures of identity functioning and ED symptom severity. RESULTS: The AN-C group showed significantly poorer overall identity functioning, poorer consolidated identity, and significantly worse disturbed and lack of identity, than the AN-PR, AN-FR, and non-ED Control groups. The AN-WR group showed significantly poorer overall identity function, and worse lack of identity, than the AN-FR and non-ED Controls, and poorer consolidated identity and disturbed identity than non-ED Controls. Identity scores did not significantly differ between AN-PR, AN-FR, and non-ED Controls. DISCUSSION: Differences in identity functioning are identifiable among individuals at different AN recovery stages, and thus may represent an important state-based feature of AN, making it an important area of consideration in treatment.

Thriving Together: An Innovative Approach to Cultivating Wellness, Emotional Health, and Lifelong Success in Graduate Nursing Students.

ABSTRACT: The rigors of graduate nursing education create significant stress for nurse anesthesia students. The taxing background of an intensive care nurse, especially during the COVID-19 pandemic, compounds the inherent pressures of doctoral study. Students often experience symptoms of burnout, complicating their ability to learn and retain critical information. We created the Thrive initiative to encourage the development of emotional wellness. Thrive's success is attributed to the blend of relevant information including emotional intelligence skills and racial sensitivity support, engaged student participation, and the desire to help the next generation of graduate nurses develop sustainable emotional health.

Body image and psychosocial outcomes in youth and young adults with differences of sex development: a multi-method study.

OBJECTIVE: Differences of sex development (DSD) can affect the physical health, appearance, and psychosocial functioning of affected individuals, but little is known about how subjective appearance perceptions (body image) impact psychosocial outcomes. This study evaluated body image and its associations with psychosocial outcomes including quality of life, resilience, and psychosocial adjustment. METHODS: This cross-sectional, multi-method study assessed body image and psychosocial outcomes including quality of life, adjustment, and resilience in 97 youth and young adults with DSD (mean age = 17 ± 3.7 years; 56% assigned female in infancy) using psychometrically sound instruments. A subsample (n = 40) completed qualitative interviews. RESULTS: Quantitative results indicated that overall, participants were satisfied with their physical appearance, although less so with their primary sex characteristics. Body image dissatisfaction was associated with poorer psychosocial adjustment, quality of life, and resilience. Qualitatively, youth and young adults reported a variety of perceptions, both positive and negative, related to their body image and the impact of living with a DSD condition. Themes identified included appearance management; effects of DSD on body image; diagnostic factors and features; attitudes about diagnosis; and treatment. CONCLUSIONS: Body image is significantly associated with psychosocial outcomes in youth and young adults with DSD, with qualitative findings highlighting both positive and negative body image experiences. Results have implications for clinical care including screening for appearance concerns, normalization of appearance variations, and intervention development to better support healthy body image and psychosocial functioning in youth and young adults with DSD.

Heterologous SARS-CoV-2 booster vaccine for individuals with hematological malignancies after a primary SARS-CoV-2 mRNA vaccine series.

Heterologous COVID-19 vaccine boosters have not been evaluated for patients with hematological malignancies. A Novavax booster was administered for 56 individuals with hematological malignancies who had received a primary COVID-19 series and prior boosters with mRNA vaccines only. Blood specimens were obtained at baseline (pre-vaccine), 28 days, and 168 days after vaccination with the Novavax booster. The median fold change of anti-Spike IgG was 1.02 (IQR 0.79, 1.3) between baseline and Day 28. Circulating Spike protein-specific B cells increased 1.4-fold at Day 28 (p < 0.05). Increases in antibody and T cell responses were modest without significance, with a waning of humoral and cellular responses at 168 days after vaccination.

Spatial and temporal analysis on the impact of ultra-low volume indoor insecticide spraying on Aedes aegypti household density.

BACKGROUND: Aedes aegypti is the primary mosquito vector for several arboviruses, such as dengue, chikungunya and Zika viruses, which cause frequent outbreaks of human disease in tropical and subtropical regions. Control of these outbreaks relies on vector control, commonly in the form of insecticide sprays that target adult female mosquitoes. However, the spatial coverage and frequency of sprays needed to optimize effectiveness are unclear. In this study, we characterize the effect of ultra-low-volume (ULV) indoor spraying of pyrethroid insecticides on Ae. aegypti abundance within households. We also evaluate the effects of spray events during recent time periods or in neighboring households. Improved understanding of the duration and distance of the impact of a spray intervention on Ae. aegypti populations can inform vector control interventions, in addition to modeling efforts that contrast vector control strategies. METHODS: This project analyzes data from two large-scale experiments that involved six cycles of indoor pyrethroid spray applications in 2 years in the Amazonian city of Iquitos, Peru. We developed spatial multi-level models to disentangle the reduction in Ae. aegypti abundance that resulted from (i) recent ULV treatment within households and (ii) ULV treatment of adjacent or nearby households. We compared fits of models across a range of candidate weighting schemes for the spray effect, based on different temporal and spatial decay functions to understand lagged ULV effects. RESULTS: Our results suggested that the reduction of Ae. aegypti in a household was mainly due to spray events occurring within the same household, with no additional effect of sprays that occurred in neighboring households. Effectiveness of a spray intervention should be measured based on time since the most recent spray event, as we found no cumulative effect of sequential sprays. Based on our model, we estimated the spray effect is reduced by 50% approximately 28 days after the spray event. CONCLUSIONS: The reduction of Ae. aegypti in a household was mainly determined by the number of days since the last spray intervention in that same household, highlighting the importance of spray coverage in high-risk areas with a spray frequency determined by local viral transmission dynamics.

Understanding benign breast disease and subsequent breast cancer in Hispanic white females; a step closer to evidence-based management.

Background While Hispanic white females (HW) have lower incidence of breast cancer (BC) than non-Hispanic white females (NHW), BC risk is unclear for HW females after benign breast disease (BBD). Methods We compared BBD characteristics and subsequent BC risk among HW and NHW females in New Mexico using a population-based collection of benign breast biopsies (1996-2007). BBD was categorized as non-proliferative disease (NPD), proliferative disease without atypia (PDWA), or atypical hyperplasia (AH). BC risk was assessed as absolute risk (AR) using cumulative incidence and relative risk (RR) by comparing the number of BC events in BBDs to non-BBD. Results This study included 3,684 HW and 6,587 NHW females with BBD. HW females had similar proportions of NPD (58.6%vs.54.3%), PDWA (21.4%vs.23.5%), and AH (3.6%vs.3.3%) as NHW. BC risk among all females with BBD was higher than population-based expected rates (RR=1.87) and was similar for HW and NHW subgroups (RR=1.99vs.1.84). As expected, BC risk increased with increasing BBD severity, both overall [RR=1.81 (NPD), 1.85 (PDWA) and 3.10 (AH)] and in the HW and NHW subgroups. Adjusted AR of BC at 5 years also increased with the severity of BBD (HW vs. NHW;NPD: 1.4 vs. 2.1%; PDWA: 1.5 vs. 2.7%; AH: 6 vs. 4.8%). Conclusions We found similar BC RRs and ARs in HW and NHW. Risk counseling should ensure that HW females receive breast cancer clinical management warranted by their similar absolute risks. Impact The present population-based provides evidence for clinical management of HW females with BBD for the prevention of BC.

The Training to Improve Dyspnoea Study- Patient Experiences of Using a High Frequency Airway Oscillating Device.

Introduction: The High Frequency Airway Oscillating device (HFAO) was developed to help patients with COPD feel less breathless through flow resistive respiratory muscle training and fixed rate oscillations. Previous work has demonstrated that this device can improve inspiratory muscle strength over and above a sham device. Both groups improved their breathlessness and preserved clinical benefits though there were no statistically significant differences seen over and above the sham device. It is important to understand patient perceptions of using a device and how this may influence their treatment and therefore a qualitative analysis was conducted to understand participant experiences of a HFAO device. Methods: This was an exploratory qualitative analysis involving participants recruited to the Training to Improve Dyspnoea (TIDe) study. Participants completed a satisfaction survey and were invited to take part in a focus group. Focus groups were conducted by a researcher independent to the randomised controlled trial. Data was analysed independently by two researchers using inductive thematic analysis, and themes/sub-themes were agreed jointly. Data is presented in themes and sub themes and triangulated with survey response data. Results: Fourteen participants were recruited to two focus groups (71% male, mean [SD] age 64[9] years). The key themes were patient selection, device use, and investment. Patient selection explores the disease characteristics, emotional impact and management of care. Device use explores the device prescription and usage, routine and lifestyle and effectiveness. Investment covers accessibility, understanding, benefits vs participation and overall perceptions of the device. Conclusion: This research demonstrates the complexity of device interventions and that key considerations should be given to patient selection, the device use itself and, the time and cost investment required for participants to successfully implement the device into daily life.

Predictors of Criminal Sentiments Scale-Modified Scores in Outpatients with Legal System Involvement.

The Criminal Sentiments Scale-Modified (CSS-M) has been widely used as a measure of criminal attitudes. This analysis examined CSS-M scores in a large sample of outpatients with serious mental illnesses and a criminal legal system history. We compared total and subscale scores in our sample to scores from two other previously published U.S. studies in which the CSS-M was used, and evaluated associations between total CSS-M score and nine variables (age, educational attainment, gender, race, marital status, employment status, diagnostic category, substance use disorder comorbidity, and adverse childhood experiences (ACE) score). Scores were higher than in two prior U.S. studies involving other types of samples. Independently significant predictors of higher CSS-M scores included being younger (P < .001), having a higher ACE score (P < .001), being male (P = 03), not identifying as White (P < 001), not having a psychotic disorder (P < 001), and having a comorbid substance use disorder (P = 002). Future research should test the hypothesis that these factors increase risk for arrest and that arrest events, and subsequent criminal legal system involvement, are characterized by negative experiences and perceptions of poor procedural justice, which in turn underpin the negative opinions referred to as "criminal sentiments" or criminal attitudes.
