Exposure therapy consortium: Outcomes of the proof-of-principle study.

Background: This paper reports on the outcomes of a proof-of-principle study for the Exposure Therapy Consortium, a global network of researchers and clinicians who work to improve the effectiveness and uptake of exposure therapy. The study aimed to test the feasibility of the consortium's big-team science approach and test the hypothesis that adding post-exposure processing focused on enhancing threat reappraisal would enhance the efficacy of a one-session large-group interoceptive exposure therapy protocol for reducing anxiety sensitivity.

Methods: The study involved a multi-site cluster-randomized controlled trial comparing exposure with post-processing (ENHANCED), exposure without post-processing (STANDARD), and a stress management intervention (CONTROL) in students with elevated anxiety sensitivity.

Nursing staff adherence to guidelines on nutritional management for critically ill patients with cancer: A service evaluation.

Background: Critically ill patients with cancer are at high risk of developing malnutrition, negatively affecting their outcome.

Aim: To critically analyse nursing staff's adherence to nutrition management guidelines for critically unwell patients with cancer and identify barriers which prevent this. Two areas of nutrition management were evaluated: early initiation (<48 h from admission) of enteral nutrition (EN) and continuation of EN without interruption.

Caveat emptor: Mental health specialty certifications and the public's preferences for clinical care.

Appropriate training and continuing education for mental health professionals are designed to ensure that clinicians provide effective and ethical care. Mental health consumers may depend upon these credentials to judge the level of a professional's competence, but whether these activities and credentials provide a valid indicator of knowledge and skills is subject to debate. The present study was designed to examine preferences for mental health clinicians among potential consumers and factors that may inform these preferences, specifically comparing preferences for doctoral-level mental health clinicians and masters-level clinicians with and without specialty certification for treating anxiety symptoms.

Augmenting the efficacy of benzodiazepine taper with telehealth-delivered cognitive behavioral therapy for anxiety disorders in patients using prescription opioids: A pilot randomized controlled trial.

The risks of concomitant benzodiazepine (BZ) and opioid use are significant. Despite the urgent need to reduce BZ use among patients taking opioids, no treatment intervention research to our knowledge has addressed treatment for this concurrent, high-risk use. The current study will evaluate the efficacy of augmenting BZ taper procedures with CBT for anxiety disorders that has been adapted specifically for patients with concomitant BZ and opioid use (either use as prescribed or misuse), a high-risk patient population.

CO reactivity as a biomarker of exposure-based therapy non-response: study protocol.

Background: Exposure-based therapy is an effective first-line treatment for anxiety-, obsessive-compulsive, and trauma- and stressor-related disorders; however, many patients do not improve, resulting in prolonged suffering and poorly used resources. Basic research on fear extinction may inform the development of a biomarker for the selection of exposure-based therapy. Growing evidence links orexin system activity to deficits in fear extinction and we have demonstrated that reactivity to an inhaled carbon dioxide (CO) challenge-a safe, affordable, and easy-to-implement procedure-can serve as a proxy for orexin system activity and predicts fear extinction deficits in rodents.

Initial assessment of the feasibility and efficacy of a scalable digital CBT for generalized anxiety and associated health behaviors in a cardiovascular disease population.

Generalized anxiety disorder (GAD) is a significant yet modifiable risk factor for worse cardiovascular disease (CVD) outcomes. The treatment of GAD in an accessible manner represents an unmet need in CVD, given that patients with CVD experience numerous barriers to in-person treatment engagement. This paper presents the rationale and design for an investigation of a strategy to enhance care for patients with CVD by introducing a scalable, affordable, and system-friendly digital intervention that targets a prominent modifiable risk factor (generalized anxiety and associated worry) for negative health behaviors in CVD.

Worrying But Not Acting: The Role of Intolerance of Uncertainty in Explaining the Discrepancy in COVID-19-Related Responses.

Unlabelled: Research indicates that Intolerance of Uncertainty (IU) is associated with COVID-19 emotional responses, but not necessarily with engaging in COVID-19 preventative behaviors. The current study was designed to further evaluate this discrepancy. Participants (N = 454) completed self-report forms about COVID-19 emotional responses (i.

Acceptability of telehealth CBT during the time of COVID-19: Evidence from patient treatment initiation and attendance records.

The COVID-19 pandemic provided unique conditions for examining outpatient psychotherapy clinics' rapid transition to telehealth. The current study utilized data from a large, specialty CBT clinic to investigate attendance and treatment engagement changes when services were provided via telehealth versus in-person. Results indicate that, following a complete transition to telehealth services, clinic referrals were maintained.

"Something is just not right with my hearing": early experiences of adults living with hearing loss.

Objective: To understand the psychosocial process of how adults experience hearing loss; specifically, their readiness to accept that they may have hearing loss, and the challenges and coping strategies associated with it.

Design: A grounded theory methodology guided the research. A patient-orientated research approach informed the study.

WNT as a Driver and Dependency in Cancer.

The WNT signaling pathway is a critical regulator of development and adult tissue homeostasis and becomes dysregulated in many cancer types. Although hyperactivation of WNT signaling is common, the type and frequency of genetic WNT pathway alterations can vary dramatically between different cancers, highlighting possible cancer-specific mechanisms for WNT-driven disease. In this review, we discuss how WNT pathway disruption contributes to tumorigenesis in different organs and how WNT affects the tumor cell and immune microenvironment.

Procalcitonin (PCT) Level in the Emergency Department Identifies a High-Risk Cohort for All Patients Treated for Possible Sepsis.

What Is Already Known?: The benefits of measuring PCT in the Emergency Department (ED) are not yet fully characterised.PCT is widely used in the intensive care setting to guide antimicrobial prescribing.

What This Adds?: Measurement of PCT as a routine in the emergency department for all patients treated for possible sepsis identifies a high-risk cohort.

An Allelic Series Reveals Distinct Phenotypes of Common Oncogenic Variants.

is the most frequently mutated oncogene in cancer, yet there is little understanding of how specific KRAS amino acid changes affect tumor initiation, progression, or therapy response. Using high-fidelity CRISPR-based engineering, we created an allelic series of new mutant mice, reflecting codon 12 and 13 mutations that are highly prevalent in lung (KRAS), pancreas (KRAS), and colon (KRAS) cancers. Induction of each allele in either the murine colon or pancreas revealed striking quantitative and qualitative differences between KRAS mutants in driving the early stages of transformation.

Platelet activating factor receptor acts to limit colitis-induced liver inflammation.

Liver inflammation is a common extraintestinal manifestation in inflammatory bowel disease (IBD), yet, the mechanisms driving gut-liver axis inflammation remain poorly understood. IBD leads to a breakdown in the integrity of the intestinal barrier causing an increase in portal and systemic gut-derived antigens, which challenge the liver. Here, we examined the role of platelet activating factor receptor (PAFR) in colitis-associated liver damage using dextran sulfate sodium (DSS) and anti-CD40-induced colitis models.

Perfectly imperfect: The use of cognitive bias modification to reduce perfectionism.

Background And Objectives: Perfectionism is a transdiagnostic risk and maintenance factor for psychopathology. The current study developed and evaluated a cognitive bias modification, interpretation retraining (CBM-I) intervention targeting maladaptive perfectionistic beliefs.

Methods: Participants were undergraduate students randomized to complete the perfectionism CBM-I (n = 33) or control condition task (n = 36) at two time points.

Evaluating the Indirect Effects of Trait Mindfulness Facets on State Tripartite Components Through State Rumination and State Experiential Avoidance.

The present study investigated whether specific trait mindfulness facets indirectly influenced state negative affect (NA), positive affect (PA), and physiological hyperarousal (PH) through state rumination and state experiential avoidance. Participants (n = 360, 68% female) rated trait mindfulness facets, then completed an interview task about life experiences intended to elicit state NA, PA, and PH. After the interview task, participants completed measures of state NA, PA, and PH, and state measures of rumination and experiential avoidance.

Examining the Relation Between Adolescent Social Anxiety and Positive Affect Regulation: Self-Report vs. Observation.

Social anxiety symptomatology is associated with disruptions in positive affect, though no study has examined deficits in responses to positive affect related to adolescent social anxiety symptoms. The present study tested whether adolescents' self-reported and observed social anxiety symptoms were uniquely associated with specific responses to positive affect. Moreover, we examined whether adolescent gender moderated these relations.

Mutation burden and other molecular markers of prognosis in colorectal cancer treated with curative intent: results from the QUASAR 2 clinical trial and an Australian community-based series.

Background: Molecular indicators of colorectal cancer prognosis have been assessed in several studies, but most analyses have been restricted to a handful of markers. We aimed to identify prognostic biomarkers for colorectal cancer by sequencing panels of multiple driver genes.

Methods: In stage II or III colorectal cancers from the QUASAR 2 open-label randomised phase 3 clinical trial and an Australian community-based series, we used targeted next-generation sequencing of 82 and 113 genes, respectively, including the main colorectal cancer drivers.

Haploinsufficiency Impairs Catalytic Activity of PARP1 and Promotes Chromosome Instability and Growth of Intestinal Tumors.

ADP-ribosylation is an important posttranslational protein modification that regulates diverse biological processes, controlled by dedicated transferases and hydrolases. Here, we show that frequent deletions (∼30%) of the mono-ADP-ribosylhydrolase locus in human colorectal cancer cause impaired PARP1 transferase activity in a gene dosage-dependent manner. haploinsufficiency alters DNA repair and sensitivity to DNA damage and results in chromosome instability.

Lymphocytic response to tumour and deficient DNA mismatch repair identify subtypes of stage II/III colorectal cancer associated with patient outcomes.

Objective: Tumour-infiltrating lymphocyte (TIL) response and deficient DNA mismatch repair (dMMR) are determinants of prognosis in colorectal cancer. Although highly correlated, evidence suggests that these are independent predictors of outcome. However, the prognostic significance of combined TIL/MMR classification and how this compares to the major genomic and transcriptomic subtypes remain unclear.

Mindfulness Facets, Social Anxiety, and Drinking to Cope with Social Anxiety: Testing Mediators of Drinking Problems.

This cross-sectional study tested social anxiety symptoms, trait mindfulness, and drinking to cope with social anxiety as potential predictors and/or serial mediators of drinking problems. A community-based sample of individuals with co-occurring social anxiety symptoms and alcohol dependence were recruited. Participants ( = 105) completed measures of social anxiety, drinking to cope with social anxiety, and alcohol use and problems.

Body Dysmorphic, Obsessive-Compulsive, and Social Anxiety Disorder Beliefs as Predictors of In Vivo Stressor Responding.

This study tested the potential transdiagnostic nature of body dysmorphic disorder (BDD), obsessive-compulsive disorder (OCD), and social anxiety disorder (SAD) beliefs, in addition to testing the specificity of those beliefs, in predicting how individuals responded to symptom-specific stressors. Participants included 127 adults (75% women) with a broad range of symptom severity. Path analysis was used to evaluate whether specific maladaptive beliefs predicted distress in response to symptom-relevant stressors over and above other beliefs and baseline distress.

Evaluating Change in Beliefs About the Importance/Control of Thoughts as a Mediator of CBM-I and Responses to an ICT Stressor.

This study evaluated an adaptation of a Cognitive Bias Modification-Interpretation (CBM-I) procedure designed to shift interpretations of intrusive thoughts related to beliefs about the Importance and Control of Thoughts (ICT). Individuals high in the ICT belief domain were randomly assigned to one of two conditions: (a) a positive (n = 38) condition in which scenarios about intrusive thoughts were repeatedly paired with benign interpretations; or (b) a control (n = 39) condition in which scenarios about intrusive thoughts were paired with 50% benign and 50% threatening interpretations. Further, participants engaged in an ICT stressor task.
