Measures Of Symptom Severity Research Articles

Sacral nerve stimulation leads to long-term improvement in fecal incontinence and quality of life for children with functional and organic defecation disorders.

Our objective was to evaluate long-term outcomes of sacral nerve stimulation (SNS) for children with functional and organic defecation disorders. We performed a prospective study of children <21 years of age who started SNS treatment between 2012 and 2018. We recorded demographics, medical history, and diagnostic testing. We obtained measures of symptom severity and quality of life at baseline and follow up at 1, 6, 12, 24, 36, 48, and ≥60 months. Successful response was defined as bowel movements >2 times/week and fecal incontinence (FI) <1 time/week. Families were contacted to administer the Glasgow Children's Benefit Inventory and to evaluate patient satisfaction. We included 65 patients (59% female, median age at SNS 14 years, range 9-21) with median follow-up of 32 months. Thirty patients had functional constipation (FC), 15 had non-retentive FI (NRFI), and 16 had an anorectal malformation (ARM). The percentage with FI <1 time/week improved from 30% at baseline to 64% at 1 year (p < 0.001) and 77% at most recent follow-up (p < 0.001). Patients with FC, NRFI, and ARM had sustained improvement in FI (p = 0.02, p < 0.001, p = 0.02). Patients also reported fewer hard stools (p = 0.001). Bowel movement frequency did not improve after SNS. At most recent follow-up, 77% of patients with a functional disorder and 50% with an organic disorder had responded (p = 0.03). Nearly all families reported benefit. SNS led to sustained improvement in FI regardless of underlying etiology, but children with functional disorders were more likely to respond than those with organic disorders.

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

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. 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. 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. 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.

Nutritional safety and status following a 12-week strict low FODMAP diet in patients with irritable bowel syndrome.

A low FODMAP diet (LFD) is an established dietary treatment for patients with irritable bowel syndrome (IBS). However, knowledge on the extended effects of the restriction phase regarding nutrient intake, symptom severity, and quality of life (QoL) is sparse. Therefore, our objectives were to evaluate the safety of a dietitian-led 12-week strict LFD on measures of blood biochemistry, nutritional status, symptom severity, and QoL. In this open-label dietitian-led 12-week strict LFD intervention for IBS patients with predominantly diarrhea or mixed stool pattern (IBS-D/-M), we collected data on diet intake (3-day dietary record), overnight fasting routine blood samples, body weight, IBS symptoms (IBS Severity Scoring System (IBS-SSS)), and IBS-related QoL (IBS-QoL) at baseline and after 12 weeks. Thirty-six participants completed the 12-week follow-up (mean age: 37 years, 67% women, IBS-SSS: 242 (101)). All blood parameters measured were within established reference values at both time points. We found no change in intake of macro- or micronutrients, but several micronutrients were below the recommendations both before and after 12 weeks. BMI slightly decreased, primarily driven by participants with BMI >25 (p < 0.005). QoL improved among most subdomains (p ≤ 0.002), except food avoidance and social reaction. An extended dietitian-guided LFD (12 weeks) is not inferior to the participants' baseline diet, since no clinically meaningful changes in nutritionally related blood samples and no changes in macro- or micronutrient intake were observed. However, the intake of several nutrients was below the recommendations at both time points indicating low diet quality.

Analysis of convolutional neural networks for fronto-temporal dementia biomarker discovery.

Frontotemporal lobe dementia (FTD) results from the degeneration of the frontal and temporal lobes. It can manifest in several different ways, leading to the definition of variants characterised by their distinctive symptomatologies. As these variants are detected based on their symptoms, it can be unclear if they represent different types of FTD or different symptomatological axes. The goal of this paper is to investigate this question with a constrained cohort of FTD patients in order to see if the heterogeneity within this cohort can be inferred from medical images rather than symptom severity measurements. An ensemble of convolutional neural networks (CNNs) is used to classify diffusion tensor images collected from two databases consisting of 72 patients with behavioural variant FTD and 120 healthy controls. FTD biomarkers were found using voxel-based analysis on the sensitivities of these CNNs. Sparse principal components analysis (sPCA) is then applied on the sensitivities arising from the patient cohort in order to identify the axes along which the patients express these biomarkers. Finally, this is correlated with their symptom severity measurements in order to interpret the clinical presentation of each axis. The CNNs result in sensitivities and specificities between 83 and 92%. As expected, our analysis determines that all the robust biomarkers arise from the frontal and temporal lobes. sPCA identified four axes in terms of biomarker expression which are correlated with symptom severity measurements. Our analysis confirms that behavioural variant FTD is not a singular type or spectrum of FTD, but rather that it has multiple symptomatological axes that relate to distinct regions of the frontal and temporal lobes. This analysis suggests that medical images can be used to understand the heterogeneity of FTD patients and the underlying anatomical changes that lead to their different clinical presentations.

Service Dogs for Veterans and Military Members With Posttraumatic Stress Disorder

Military members and veterans (hereafter, veterans) with posttraumatic stress disorder (PTSD) increasingly seek psychiatric service dogs as a complementary intervention, yet the effectiveness of service dogs is understudied. To estimate the associations between psychiatric service dog partnership and self-reported and clinician-rated PTSD symptom severity, depression, anxiety, and psychosocial functioning after 3 months of intervention among veterans. This nonrandomized controlled trial used standardized and validated assessment instruments completed by participants and administered by blinded clinicians. Recruitment, eligibility screening, and enrollment were conducted between August 2017 and December 2019. Veterans were recruited using the database of an accredited nonprofit service dog organization with constituents throughout the US. Participants were veterans with a PTSD diagnosis; they were allocated to either the intervention group (n = 81) or control group (n = 75). Outcome assessments were performed at baseline and at the 3-month follow-up. Data analyses were completed in October 2023. Participants allocated to the intervention group received a psychiatric service dog for PTSD, whereas those allocated to the control group remained on the waiting list based on the date of application submitted to the service dog organization. Both groups had unrestricted access to usual care. The primary outcomes were PTSD symptom severity, depression, and anxiety after 3 months, and the secondary outcomes were psychosocial functioning, such as quality of life and social health. The self-reported PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was used to measure symptom severity, and the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) was used to assess PTSD diagnosis (score range for both instruments: 0-80, with higher scores indicating greater PTSD symptoms). The 156 participants included in the trial had a mean (SD) age of 37.6 (8.3) years and included 117 males (75%), 17 Black or African American individuals (11%), 30 Hispanic individuals (19%), and 117 White individuals (76%). Compared with the control group, the intervention group had significantly lower PTSD symptom severity based on the PTSD Checklist for DSM-5 mean (SD) score (41.9 [16.9] vs 51.7 [16.1]; difference in means, -11.5 [95% CI, -16.2 to -6.6]; P < .001) and the CAPS-5 mean (SD) score (30.2 [10.2] vs 36.9 [10.2]; difference in means, -7.0 [95% CI, -10.8 to -4.5]; P < .001) at 3 months. The intervention group also had significantly lower depression scores (odds ratio [OR], 0.45 [95% CI, 0.23-0.86]; difference in means, -3.3 [95% CI, -6.8 to -0.6]), anxiety (OR, 0.25 [95% CI, 0.13-0.50]; difference in means, -4.4 [95% CI, -6.9 to -2.1]), and most areas of psychosocial functioning (eg, social isolation: OR, 0.34 [95% CI, 0.18-0.64]). This nonrandomized controlled trial found that compared with usual care alone, partnership with a trained psychiatric service dog was associated with lower PTSD symptom severity and higher psychosocial functioning in veterans. Psychiatric service dogs may be an effective complementary intervention for military service-related PTSD. ClinicalTrials.gov ID: NCT03245814.

Incompleteness as a clinical characteristic and predictor of treatment outcome in obsessive-compulsive disorder

Incompleteness, that is, a feeling that things are “not just right”, is an understudied symptom of obsessive-compulsive disorder (OCD). We used data from 167 adult individuals with OCD who received internet-delivered cognitive behaviour therapy (ICBT) to examine how incompleteness was associated with clinical characteristics and treatment outcomes. Incompleteness was assessed using the Obsessive-Compulsive Trait Core Dimensions Questionnaire (OCTCDQ). Results showed that the proposed two-factor structure of the OCTCDQ had adequate model/data fit in the present sample. Incompleteness was positively associated with baseline symmetry/ordering symptoms (β = 0.52, [95% CI 0.48 to 0.56], p < 0.001), psychiatric comorbidity (β = 0.23, [95% CI 0.21 to 0.25], p < 0.05) and self-reported symptom severity (Y-BOCS-SR β = 0.35, [95% CI 0.27 to 0.43], p < 0.001; OCI-R β = 0.46, [95% CI 0.34 to 0.59], p < 0.001). Results showed that higher degree of incompleteness predicted a worse treatment outcome on clinician-rated, but not self-rated, measures of symptom severity. Participants with a high (vs. low) degree of incompleteness were less likely to be classified as responders (39% vs. 52%) and remitters (10% vs. 34%) at post-treatment. The results suggest that incompleteness is a clinically relevant feature of OCD, which may require treatment adaptations for some patients but more research is needed to confirm that the findings are not entirely due to measurement error.

Predicted Brain Age in First-Episode Psychosis: Association with Inexpressivity.

Accelerated brain aging is a possible mechanism of pathology in schizophrenia. Advances in MRI-based brain development algorithms allow for the calculation of predicted brain age (PBA) for individuals. Here, we assessed PBA in 70 first-episode schizophrenia-spectrum individuals (FESz) and 76 matched healthy neurotypical comparison individuals (HC) to determine if FESz showed advanced aging proximal to psychosis onset and whether PBA was associated with neurocognitive, social functioning, or symptom severity measures. PBA was calculated with BrainAgeR (v2.1) from T1-weighted MR scans. There were no differences in the PBAs between groups. After controlling for actual age, a "younger" PBA was associated with higher vocabulary scores among all individuals, while an "older" PBA was associated with more severe negative symptom "Inexpressivity" component scores among FESz. Female participants in both groups had an elevated PBA relative to male participants. These results suggest that a relatively younger brain age is associated with a better semantic memory performance. There is no evidence for accelerated aging in FESz with a late adolescent/early adult onset. Despite a normative PBA, FESz with a greater residual PBA showed impairments in a cluster of negative symptoms, which may indicate some underlying age-related pathology proximal to psychosis onset. Although a period of accelerated aging cannot be ruled out with disease course, it does not occur at the time of the first episode.

A Pilot Study of a Trauma Resiliency Protocol for Law Enforcement Officers With Posttraumatic Stress Disorder Symptoms.

The aim of the study is to test the efficacy of the 22ZERO Trauma Resiliency Protocol (TR-P) on posttraumatic stress disorder (PTSD) symptom severity among current and former law enforcement officers. The study used a retrospective, pre/post intervention design to test the effects of the TR-P on measures of self-reported symptom severity. One hundred twenty-eight current and former law enforcement officers were exposed to the TR-P treatment. All participants were administered the PTSD Checklist for DSM-5 PTSD Checklist and other psychological assessments before and after exposure. Participants experienced a significant reduction in symptom severity, suggesting that exposure to the TR-P reduced the effects of PTSD in this sample of law enforcement officers. The 22ZERO TR-P may be an efficacious mechanism for reducing PTSD symptom severity among current and former law enforcement officers. It should be tested using a randomized trial and a longer follow-up period.

Using recursive partitioning to predict presence and severity of suicidal ideation amongst college students

Objective Predicting the presence and severity of suicidal ideation in college students is important, as deaths by suicide amongst young adults have increased in the past 20 years. Participants We recruited college students (N = 5494) from ten universities across eight states. Method Participants answered three questionnaires related to lifetime and past month suicidal ideation, and an indicator of suicidal ideation in a DSM-5 symptom measure. We used recursive partitioning to predict the presence, absence, and severity, of suicidal ideation. Results Recursive partitioning models varied in their accuracy and performance. The best-performing model consisted of predictors and outcomes measured by the DSM-5 Level 1 Cross-Cutting Symptom Measure. Sexual orientation was also an important predictor in most models. Conclusions A single measure of DSM-5 symptom severity may help universities understand suicide severity to promote targeted interventions. Though further work is needed, as similar scaling amongst predictors could have influenced the model.

Estimating dynamic treatment regimes for ordinal outcomes with household interference: Application in household smoking cessation.

The focus of precision medicine is on decision support, often in the form of dynamic treatment regimes, which are sequences of decision rules. At each decision point, the decision rules determine the next treatment according to the patient's baseline characteristics, the information on treatments and responses accrued by that point, and the patient's current health status, including symptom severity and other measures. However, dynamic treatment regime estimation with ordinal outcomes is rarely studied, and rarer still in the context of interference - where one patient's treatment may affect another's outcome. In this paper, we introduce the weighted proportional odds model: a regression based, approximate doubly-robust approach to single-stage dynamic treatment regime estimation for ordinal outcomes. This method also accounts for the possibility of interference between individuals sharing a household through the use of covariate balancing weights derived from joint propensity scores. Examining different types of balancing weights, we verify the approximate double robustness of weighted proportional odds model with our adjusted weights via simulation studies. We further extend weighted proportional odds model to multi-stage dynamic treatment regime estimation with household interference, namely dynamic weighted proportional odds model. Lastly, we demonstrate our proposed methodology in the analysis of longitudinal survey data from the Population Assessment of Tobacco and Health study, which motivates this work. Furthermore, considering interference, we provide optimal treatment strategies for households to achieve smoking cessation of the pair in the household.

An update of palliative care in lung transplantation with a focus on symptoms, quality of life and functional outcomes.

Palliative care (PC) in lung transplantation is increasingly acknowledged for its important role in addressing symptoms, enhancing functionality, and facilitating advance care planning for patients, families, and caregivers. The present review provides an update in PC management in lung transplantation. Research confirms the effectiveness of PC for patients with advanced lung disease who are undergoing transplantation, showing improvements in symptoms and reduced healthcare utilization. Assessment tools and patient-reported outcome measures for PC are commonly used in lung transplant candidates, revealing discrepancies between symptom severity and objective measures such as exercise capacity. The use of opioids to manage dyspnea and cough in the pretransplant period is deemed safe and does not heighten risks posttransplantation. However, the integration of PC support in managing symptoms and chronic allograft dysfunction in the posttransplant period has not been as well described. Palliative care support should be provided in the pretransplant and select peri-operative and posttransplant periods to help support patient quality of life, symptoms, communication and daily function.

Abstract 6304: Seizure self-report and monitoring: Agreement between patient and clinician report and implications for care in patients with IDH-mutant and IDH-wild type gliomas

Abstract Primary brain tumor (PBT) patients commonly experience seizures, which can be measured and monitored by a variety of tools. Here, we explore the concordance between 2 tools and their use in reporting seizures over time among PBT patients enrolled in a natural history study (NCT02851706, PI: T. Armstrong). Patients complete the M.D. Anderson Symptom Inventory - Brain Tumor (MDASI-BT), which measures symptom severity (including seizure) within the last 24 hours from 0-10; and, as part of the same visit, pairs of clinicians and patients complete the Seizure Control Composite Index (RANO-SCCI), which includes the questions ‘Have you ever had a seizure’ (RANO-SCCIQ1) and ‘Have you had a seizure since your last clinic visit’ (RANO-SCCIQ2). Responses to each measure are reported in aggregate and by IDH status. Participants included 89 patients with gliomas who were primarily white (84%) males (62%) with a median age of 48 years (range: 27-78) and KPS ≥ 90 (85%). Based on patient reports, 65% endorsed ever having a seizure (RANO-SCCIQ1), 17% had a recent seizure (RANO-SCCIQ2), and 12% had a seizure within the last 24 hours (MDASI-BT). For the RANO-SCCIQ1 data, patients and clinicians generally agreed except for 6 pairs (7%) where clinicians indicated a seizure but patients did not. Of the 59 who reported recent seizures (RANO-SCCIQ2), two pairs (3%) disagreed, with patients indicating a recent seizure but clinicians not endorsing a seizure had occurred. Good overall agreement (86%) was observed between the RANO-SCCIQ2 and MDASI-BT for both clinician and patient responses, with 3 and 2 paired disagreements respectively, in which seizures were indicated in the last 24 hours but not recorded as a recent seizure on the (RANO-SCCIQ2). Comparing clinician report of seizures in those with IDH-mutated (n=39) to IDH-wildtype (n=15) tumors, 85% (33/39) versus 47% (7/15) reported ever having a seizure and 7 of 33 (21%) with IDH-mutant and 1 of 7 (14%) with IDH-wild type (IDH-WT) tumors respectively reported a seizure since the last visit. Disparities in recognition of seizures between patient and clinician highlights a need for patient education to increase awareness of events and recognition of ongoing risk. Although those with IDH-mutated tumors are at higher risk of having seizures, nearly half of those with IDH-WT reported ever having seizures, underscoring the need for all patients to be educated on recognizing and assessing seizure symptoms.

Compassion Meditation for Distressed Older Veterans: A Feasibility Study

ABSTRACT Objectives Older Veterans are at elevated risk for psychological distress and may encounter barriers to accessing mental health services. Compassion Meditation (CM) promotes positive emotions and outcomes among distressed individuals; thus, we conducted a preliminary feasibility study of CM among distressed older Veterans. Methods Participants included 25 Veterans aged 55+ (M = 69.0, SD = 10.6) with anxiety and/or depressive symptoms, recruited from primary care, mostly male (76.0%), and White (60.0%). CM consisted of 10 groups, which were transitioned from in-person to telehealth due to COVID-19. Feasibility indices included rates of intervention initiation and completion, and attendance. Participants completed measures of symptom severity and well-being pre- and post-intervention. Results Of 25 enrolled participants, 88.0% (n = 22) attended at least one session, and 52% (n = 13) completed the intervention (attended six or more sessions). Among intervention completers, the average number of sessions attended was 9.46. Seven Veterans withdrew from intervention due to difficulties engaging via telehealth. Conclusions These findings support the feasibility of CM training in older Veterans with psychological distress, though dropouts highlighted potential need for additional strategies to facilitate telehealth participation. Clinical Implications Older Veterans appear amenable to meditation-based practices, provided they are easy to access.

Urged to feel certain again: The role of emotion-related impulsivity on the relationships between intolerance of uncertainty and OCD symptom severity.

Obsessive-compulsive disorder (OCD) is a debilitating mental disorder characterized by persistent and intrusive thoughts accompanied by repetitive mental or physical acts. While both intolerance of uncertainty and emotion-related impulsivity have been consistently evidenced as cognitive risk factors of OCD, no studies have considered their joint effects. The current study examined the interaction between intolerance of uncertainty and two forms of emotion-related impulsivity-including both a behavioural and cognitive form-in predicting OCD symptoms. Cross-sectional data were collected online from community-based adult participants. Participants (N = 673) completed a battery of self-report measures of OCD symptom severity, intolerance of uncertainty, and emotion-related impulsivity. The behavioural form of emotion-related impulsivity positively moderated the relationship between intolerance of uncertainty and OCD symptoms. Elevated levels of both factors predicted the most severe symptoms, particularly checking, washing, and obsessing. This interaction effect was not found for the cognitive form of emotion-related impulsivity, which still emerged as a unique predictor of OCD symptom severity, specifically obsessing symptoms. Current findings furthered the understanding of the link between intolerance of uncertainty and OCD symptoms by highlighting the role of emotion-related impulsivity. When uncertainty triggers distress in individuals with high intolerance of uncertainty, the urge to behaviourally alleviate this distress could promote the use of maladaptive obsessions and compulsions, leading to greater OCD symptoms. Results also indicated the potentially differential effects from the behavioural versus cognitive forms of emotion-related impulsivity on different symptom domains, and the mechanistic link here is worthy of further investigation.

The Effect of Cognitive Fusion on Change in PTSD and Depression Symptom Severity in Veterans Engaged in Group Psychotherapy.

Cognitive fusion occurs when people experience their thoughts as literally true and allow them to dictate behavior. Fusion has been shown to be associated with increased symptoms of post-traumatic stress disorder (PTSD) and depression; however, the association between change in cognitive fusion, PTSD, and depression symptoms has been relatively uninvestigated. Our study aims to examine the associations between PTSD, depression symptoms, and cognitive fusion in Canadian veterans from pre- to post-treatment. Clients (N = 287) completed measures of PTSD symptom severity, depression symptom severity, and cognitive fusion at pre- and post-treatment. Our results supported that pretreatment PTSD and depression symptom severity were found to be negatively associated with changes in pre- to post-treatment cognitive fusion, while pretreatment cognitive fusion was not associated with changes in depression or PTSD symptoms. Furthermore, pretreatment depression symptoms predicted pre- to post-treatment changes in PTSD symptoms. However, pretreatment PTSD symptoms did not predict changes in depression symptoms. These findings highlight the importance of understanding the bidirectional associations between PTSD, depression, and cognitive fusion. Furthermore, our results are indicative of PTSD and depression symptoms playing a role in the change in cognitive fusion (e.g., defusion) and of depression playing a larger role in the maintenance of PTSD symptoms. Theoretical and practical implications are discussed.

Decreased uncinate fasciculus integrity in functional seizures following traumatic brain injury.

The uncinate fasciculus (UF) has been implicated previously in contributing to the pathophysiology of functional (nonepileptic) seizures (FS). FS are frequently preceded by adverse life events (ALEs) and present with comorbid psychiatric symptoms, yet neurobiological correlates of these factors remain unclear. To address this gap, using advanced diffusion magnetic resonance imaging (dMRI), UF tracts in a large cohort of patients with FS and pre-existing traumatic brain injury (TBI + FS) were compared to those in patients with TBI without FS (TBI-only). We hypothesized that dMRI measures in UF structural connectivity would reveal UF differences when controlling for TBI status. Partial correlation tests assessed the potential relationships with psychiatric symptom severity measures. Participants with TBI-only (N = 46) and TBI + FS (N = 55) completed a series of symptom questionnaires and MRI scanning. Deterministic tractography via diffusion spectrum imaging (DSI) was implemented in DSI studio (https://dsi-studio.labsolver.org) with q-space diffeomorphic reconstruction (QSDR), streamline production, and manual segmentation to assess bilateral UF integrity. Fractional anisotropy (FA), radial diffusivity (RD), streamline counts, and their respective asymmetry indices (AIs) served as estimates of white matter integrity. Compared to TBI-only, TBI + FS participants demonstrated decreased left hemisphere FA and RD asymmetry index (AI) for UF tracts (both p < .05, false discovery rate [FDR] corrected). Additionally, TBI + FS reported higher symptom severity in depression, anxiety, and PTSD measures (all p < .01). Correlation tests comparing UF white matter integrity differences to psychiatric symptom severity failed to reach criteria for significance (all p > .05, FDR corrected). In a large, well-characterized sample, participants with FS had decreased white matter health after controlling for the history of TBI. Planned follow-up analysis found no evidence to suggest that UF connectivity measures are a feature of group differences in mood or anxiety comorbidities for FS. These findings suggest that frontolimbic structural connectivity may play a role in FS symptomology, after accounting for prior ALEs and comorbid psychopathology severity.

Comparative effectiveness of pelvic floor muscle training, mirabegron, and trospium among older women with urgency urinary incontinence and high fall risk: a feasibility randomized clinical study

BackgroundUntreated, urgency urinary incontinence (UUI) and overactive bladder (OAB) can precipitate a vicious cycle of decreasing physical activity, social isolation, fear of falling, and falls. Structured behavioral interventions and medications are common initial treatment options, but they elicit their effects through very different mechanisms of action that may influence fall-related outcomes differently. This study will determine the feasibility of conducting a comparative effectiveness, three-arm, mixed methods, randomized clinical trial of a behaviorally based pelvic floor muscle training (PFMT) intervention versus two recent drug options in older women with UUI or OAB who are also at increased risk of falling.MethodsForty-eight women 60 years and older with UUI or OAB who screen positive for increased fall risk will be recruited through the urogynacology and pelvic health clinics of our university health system. Participants will be randomly assigned to one of three 12-week treatment arms: (1) a course of behavioral and pelvic floor muscle training (PFMT) provided by physical therapists; (2) the beta-3 agonist, mirabegron; and (3) the antimuscarinic, trospium chloride. Study feasibility will be established through objective metrics of evaluability, adherence to the interventions, and attrition. We will also assess relevant measures of OAB symptom severity, quality of life, physical activity, incident falls, and concern about falling.DiscussionThe proposed research seeks to ultimately determine if linkages between reduction in UI symptoms through treatment also reduce the risk of falling in this patient population.Trial registrationNCT05880862.

Validation of a measure of hypervigilance and anxiety about gastrointestinal symptoms for individuals with elevated eating pathology.

Gastrointestinal symptoms are common within eating disorders and gastrointestinal-specific anxiety is a posited maintenance factor. The present study sought to validate a modified version of an existing measure of gastrointestinal-specific anxiety and hypervigilance in a sample with elevated eating pathology. Esophageal-specific terms in the Esophageal Hypervigilance and Anxiety Scale were modified to measure any gastrointestinal symptoms as a general measure of gastrointestinal-specific anxiety and hypervigilance. Three hundred eighty-two undergraduate students (83.5% female, 87.4% White) with elevated eating pathology completed a questionnaire battery that also measured gastrointestinal symptoms, general anxiety sensitivity, and lower gastrointestinal-specific anxiety on two occasions. Analyses were preregistered at Open Science Framework. Confirmatory factor analysis indicated a two-factor solution (anxiety and hypervigilance) fit the data best. Internal consistency and 2-week test-retest reliability were good for subscale scores. Subscale scores exhibited large associations with a measure of lower gastrointestinal-specific anxiety but did not exhibit the hypothesized relationships with general anxiety sensitivity. Subscale scores were at least moderately correlated with measures of gastrointestinal symptoms and somatic symptom severity, with some exceptions (hypervigilance with nausea/vomiting, postprandial fullness/early satiety, bloating). Subscale scores exhibited negligible associations with discriminant validity measures. Results suggest that gastrointestinal-specific anxiety and hypervigilance are separable in samples with elevated eating pathology. The Anxiety and Hypervigilance subscale scores showed good reliability in a sample with elevated eating pathology. Correlations with measures of gastrointestinal symptoms and gastrointestinal-specific anxiety generally demonstrated good convergent and discriminant validity. We recommend researchers use subscale scores, rather than total score, in future research on gastrointestinal symptoms associated with eating pathology.

Proxy measures for the assessment of psychotic and affective symptoms in studies using electronic health records.

There is a lack of standardised psychometric data in electronic health record (EHR)-based research. Proxy measures of symptom severity based on patients' clinical records may be useful surrogates in mental health EHR research. This study aimed to validate proxy tools for the short versions of the Positive and Negative Syndrome Scale (PANSS-6), Young Mania Rating Scale (YMRS-6) and Montgomery-Åsberg Depression Rating Scale (MADRS-6). A cross-sectional, multicentre study was conducted in a sample of 116 patients with first-episode psychosis from 12 public hospitals in Spain. Concordance between PANSS-6, YMRS-6 and MADRS-6 scores and their respective proxies was evaluated based on information from EHR clinical notes, using a variety of statistical procedures, including multivariate tests to adjust for potential confounders. Bootstrapping techniques were used for internal validation, and an independent cohort from the Treatment and Early Intervention in Psychosis Program (TIPP-Lausanne, Switzerland) for external validation. The proxy versions correlated strongly with their respective standardised scales (partial correlations ranged from 0.75 to 0.84) and had good accuracy and discriminatory power in distinguishing between patients in and not in remission (percentage of patients correctly classified ranged from 83.9 to 91.4% and bootstrapped optimism-corrected area under the receiver operating characteristic curve ranged from 0.76 to 0.89), with high interrater reliability (intraclass correlation coefficient of 0.81). The findings remained robust in the external validation data-set. The proxy instruments proposed for assessing psychotic and affective symptoms by reviewing EHR provide a feasible and reliable alternative to traditional structured psychometric procedures, and a promising methodology for real-world practice settings.

Midfrontal theta reactivity to conflict and error are linked to externalizing and internalizing respectively.

Dimensional psychopathology scores measure symptom severity; cutting across disorder categories. Their clinical utility is high given comorbidity, but their neural basis is unclear. We used scalp electroencephalography (EEG) to concurrently assess neural activity across internalizing and externalizing traits. "Theta rhythm" (4-7Hz) spectral power at the frontal midline site Fz in specific goal conflict and action error phases within a trial of a Stop-Signal Task was extracted using process-specific contrasts. A final sample of 146 community participants (63 males, 83 females; mean age = 36; SD = 9; range = 18 - 56), oversampled for externalizing disorder (49% diagnosed with a DSM-5 externalizing disorder), also supplied psychopathology and personality data. We used the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) to measure symptoms and traits of psychopathology. An MMPI-3 measure of the higher-order internalizing psychopathology spectrum was positively correlated with action error theta. An MMPI-3 measure of the higher-order spectrum of externalizing psychopathology was negatively correlated with goal-conflict theta. We showed that goal-conflict and error theta activity are higher-order processes that index psychopathology severity. The associations extend into the nominally healthy range, and so reflect theta-related factors that apply to the general population as well as patients with sub-threshold diagnoses.
