This rapid review presents the evidence base for CBT for people with COPD and describes 1) the nature of CBT interventions and comparators in controlled trials (high or low resource intensity); and 2) factors influencing intervention effects on health outcomes (anxiety, depression, breathlessness, quality of life and exercise capacity). Primary studies reporting CBT interventions in adults with COPD were identified with data extracted by a single reviewer (20% of studies checked for data accuracy). Studies were synthesized descriptively with meta-analyses (random effects models) of controlled trials undertaken to report mean standardized effect sizes (95% CI) for health outcomes. Random effects meta-regression models explored whether CBT target, intervention dosage, intensity, facilitator profession, delivery mode, clinically significant anxiety/depression, trial design/quality and sample size predicted effect size. The search identified 33 primary studies published between 1996 and 2019 (controlled trials n=24, single group cohort n=6, case exemplars n=2, phenomenological n=1). Controlled trials frequently compared high-intensity CBT interventions against enhanced/usual care (n=12) or high-intensity CBT interventions against high-intensity comparators (n=11). When all controlled studies were included, small, significant improvements favoring CBT were evident across all health outcomes (SMD ranged from − 0.27 to 0.35, p< 0.05). When intensity dyads were considered, significant improvements were evident only when high-intensity CBT interventions were compared to enhanced usual care/usual care (SMDs ranged from − 0.45 to 0.54, p < 0.05). No other variable consistently predicted intervention effect sizes across all health outcomes. Overall, the evidence base supports the use of CBT for a range of health outcomes in people with COPD. Consistent benefits were evident when high-resource-intensive CBT interventions were compared to usual care. Low-resource-intensity CBT warrants further investigation in settings where cost of comprehensive care is prohibitive.Keywords: cognitive behavioral therapy, chronic obstructive pulmonary disease, rapid review

Marie T Williams,1 Tanja W Effing,2,3 Catherine Paquet,4 Carole A Gibbs,5 Hayley Lewthwaite,1 Lok Sze Katrina Li,6 Anna C Phillips,6 Kylie N Johnston6 1Health and Alliance for Research in Exercise, Nutrition and Activity (ARENA), School of Health Sciences, Sansom Institute for Health Research, University of South Australia, 2Department of Respiratory Medicine, Repatriation General Hospital, 3School of Medicine, Flinders University, 4Division of Health Sciences, Centre for Population Health Research, School of Health Sciences, Sansom Institute for Health Research, 5Library, University of South Australia, 6Division of Health Sciences, School of Health Sciences, Sansom Institute for Health Research, University of South Australia, Adelaide, SA, Australia Abstract: Counseling has been suggested as a promising approach for facilitating changes in health behavior. The aim of this systematic review of counseling interventions for people with COPD was to describe: 1) counseling definitions, 2) targeted health behaviors, 3) counseling techniques and 4) whether commonalities in counseling techniques were associated with improved health behaviors. Ten databases were searched for original randomized controlled trials which included adults with COPD, used the term “counseling” as a sole or component of a multifaceted intervention and were published in the previous 10 years. Data extraction, study appraisal and coding for behavior change techniques (BCTs) were completed by two independent reviewers. Data were synthesized descriptively, with meta-analysis conducted where possible. Of the 182 studies reviewed as full-text, 22 were included. A single study provided a definition for counseling. Two key behaviors were the main foci of counseling: physical activity (n=9) and smoking cessation (n=8). Six studies (27%) reported underlying models and/or theoretical frameworks. Counseling was the sole intervention in 10 studies and part of a multicomponent intervention in 12. Interventions targeting physical activity included a mean of 6.3 (±3.1) BCTs, smoking cessation 4.9 (±2.9) BCTs and other behaviors 6.5 (±3.9) BCTs. The most frequent BCTs were social support unspecified (n=22; 100%), goal setting behavior (n=11), problem-solving (n=11) and instructions on how to perform the behavior (n=10). No studies shared identical BCT profiles. Counseling had a significant positive effect for smoking cessation and positive but not significant effect for physical activity. Counseling for health behavior change was rarely defined and effectiveness varied by target behavior. Provision of specific details when reporting studies of counseling interventions (definition, BCTs, dosage) would allow clarification of the effectiveness of counseling as an approach to health behavior change in people with COPD.

Consequently, adult offspring of parents with COPD may be at a greater risk of developing COPD. The aim of this study was to review the prevalence of co-occurrence of COPD in adult offspring with one or both parents having COPD independent of specific genetic variations.Methods: In total, five databases were searched for original studies in which prevalence of COPD was reported in both offspring (children) and one or both parents. Studies were excluded if COPD was not clearly defined, COPD was linked to specific genetic variations, COPD was combined with other chronic respiratory conditions, or estimates included other first-degree relatives. Data extraction (ie, sample characteristics, prevalence of COPD, and odds ratio [OR] if reported) was completed by two independent reviewers. A meta-analysis of prevalence and OR was conducted, where possible. Results: Of the 3,382 citations, 129 full texts were reviewed to include eight studies (six case–control, one cross-sectional, and one cohort) reflecting either prevalence of COPD in offspring of parents with COPD (descendent approach, n=3), which ranged from 0% to 17.3%, or prevalence of people with COPD reporting positive parental history of COPD (antecedent approach, n=5), for which the pooled prevalence was 28.6%. Offspring of people with COPD had 1.57 times greater odds (95% confidence interval =1.29–1.93; P

RG is a rare optical complication of femtosecond laser-assisted in situ keratomileusis that results in patients seeing an array of spectral bands surrounding point sources of light under mesopic and scotopic conditions. The mechanism is thought to be a consequence of the formation of a transmissive diffraction grating on the posterior surface of the corneal flap created by the FS laser. RG has a good prognosis and is usually self-limiting. Persistent RG with concomitant residual refractive error may warrant lifting the flap and photoablating the posterior surface of the flap. Patients with persistent RG and no residual refractive error should be considered candidates for phototherapeutic keratectomy on the posterior flap surface.

Toby Hunt,1,2 Sarah Madigan,2 Marie T Williams,3 Tim S Olds1 1Alliance for Research in Exercise, Nutrition and Activity (ARENA), Sansom Institute for Health Research, School of Health Sciences, University of South Australia, City East Campus, Adelaide, SA, Australia; 2Respiratory Clinical Research Unit, Repatriation General Hospital, Daw Park, SA, Australia; 3School of Population Health, University of South Australia, City East Campus, Adelaide, SA, Australia Abstract: “Physical inactivity” and “sedentary lifestyles” are phrases often used when describing lifestyles of people with chronic obstructive pulmonary disease (COPD). Evidence suggests activity types, independent of energy expenditure, influence health outcomes, so understanding patterns of time use is important, particularly in chronic disease. We aimed to identify reports of time use in people with COPD. Predefined search strategies were used with six electronic databases to identify individual activity reports (including frequencies and/or durations) in which community-dwelling people with COPD engaged. Eligible studies were assessed independently against predefined criteria and data were extracted by two reviewers. Data synthesis was achieved by aggregating activity reports into activity domains (sports/exercise, screen time, transport, quiet time, self-care, sociocultural, work/study, chores, and sleep). Twenty-six publications reported 37 specific daily activities. People with COPD were found to spend extended periods in sedentary behaviors (eg, standing [194 min/day]; sitting [359 min/day]; lying [88 min/day]), have limited engagement in physical activity (eg, walking [51 min/day]; exercising [1.2 episodes per week {ep/w}, 13 min/day]), have high health care needs (medical appointments [1.0 ep/w]), and experience difficulties associated with activities of daily living (eg, showering [2.5 ep/w, 60 minutes per episode]; preparing meals [4.7 ep/w]). Little data could be found describing how people with COPD use their time, and data synthesis was problematic because of variations in methodologies, population differences, and research emphases. Identified data largely referred to posture and were skewed according to country, assessment methods, and disease severity. Comparisons with age-matched population data showed people with COPD spent less time engaged in personal-care activities (self-care and sleeping) and chores than people in similar age groups. The incorporation of time-use outcomes in future research designs should be encouraged. Ideally, these tools should use consistent frameworks and comparable outcome measures in order to provide clearer descriptions of time use in chronic disease.

Background: Several studies have identified discrete symptom dimensions in obsessive-compulsive disorder (OCD), derived from factor analyses of the individual items or symptom categories of the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist (YBOCS-SC). This study aims to extend previous work on the relationship between obsessions and compulsions by specifically including mental compulsions and reassurance-seeking. Because these compulsions have traditionally been omitted from prior factor analytic studies, their association to what have been called "pure obsessions" may have been overlooked.Method: Participants (N = 201) were recruited from two multi-site randomized clinical treatment trials for OCD. The YBOCS-SC was used to assess OCD symptoms, as it includes a comprehensive list of obsessions and compulsions, arranged by content category. Each category was given a score based on whether symptoms were present and if the symptom was a primary target of clinical concern, and a factor analysis was conducted. Mental compulsions and reassurance-seeking were considered separate categories for the analysis.Results: Using an orthogonal geomin rotation of 16 YBOCS-SC categories/items, we found a five-factor solution that explained 67% of the total variance. Inspection of items that composed each factor suggests five familiar constructs, with mental compulsions and reassurance-seeking included with sexual, aggressive, and religious obsessions (unacceptable/taboo thoughts).Conclusions: This study suggests that the concept of the "pure obsessional" (e.g., patients with unacceptable/taboo thoughts yet no compulsions) may be a misnomer, as these obsessions were factorially associated with mental compulsions and reassurance-seeking in these samples. These findings may have implications for DSM-5 diagnostic criteria. [ABSTRACT FROM AUTHOR]

Electrophysical agents have been a core part of physiotherapy practice since the establishment of the profession. However, significant changes in the health arena over the last 20 years have challenged the place of electrophysical agents as a core aspect of physiotherapy practice. The development of manual techniques and a greater focus on exercise therapies and evidence based practice have led to a shift in the way physiotherapists view and use electrophysical agents. At the same time, the types and complexity of electrophysical equipment has increased considerably. These changes create difficulties in determining which electrophysical agents should be included in entry level physiotherapy curricula. Using electrophysical agents as an example, this paper presents the challenges facing the profession in terms of what and how decisions concerning entry-level physiotherapy curricula may be made. A framework for integrating both clinical practice trends and research evidence is presented as a means for determining entry level physiotherapy curricula in the next ten years.

Health Related Quality of Life (HRQOL) is an important outcome in the delivery of health care. Research on the HRQOL in young people with cerebral palsy (CP) has relied on proxy-reports from parents. The purpose of this study was to investigate the self-reported HRQOL of young people with CP. A survey was mailed to 229 adolescents with CP in South Australia, of which 118 responded (51.5%). Seventy-one participants 11 to 17 years of age, self-reported HRQOL on the Pediatric Quality of Life Inventory 4.0 (PedsQL). Thirty-eight youth were deemed by their parent/guardian as having insufficient cognitive ability to self-report HRQOL and nine respondents returned their surveys incomplete. The mean PedsQL Physical Function score was 57.3 (SD = 24.3), the mean Psychosocial Function score was 64.5 (SD = 15.9), and the Overall PedsQL score was 62.0 (SD = 16.7). Compared to norms for children without disabilities, 67% of participants had an Overall PedsQL score greater than I SD below the mean. PedsQL scores were related to gross motor function classification level (Spearman's rho = -0.54), number of health issues (rho = -0.51), and socioeconomic status (rho = 0.28), but not age, gender, quality of sleep, or whether parent assistance was needed to complete the PedsQL. The results have implications for policy and efforts to identify and address barriers to full and satisfying participation in main-stream schools and community activities. [ABSTRACT FROM AUTHOR]

Questions: What is the volume, quality, consistency, and generalisability of the evidence for breathing control? What is the effect on outcomes related to the target and mechanism of breathing control, as well as physiological and clinical outcomes? Design: Systematic review with meta-analysis. Participants: People with chronic respiratory disease, post-surgical, or asymptomatic individuals. Intervention: Breathing control (relaxed basal, diaphragmatic, or abdominal breathing) as the sole intervention. Outcome measures: All outcome measures providing continuous data. Results: Twenty studies were included within the meta-analysis. A beneficial effect was found for abdominal movement (SMD 1.36, 95% CI 0.42 to 2.31), diaphragm excursion (SMD 1.39, 95% CI 1.00 to 1.77), respiratory rate (SMD -0.84, 95% CI -1.09 to -0.60), tidal volume (SMD 0.98, 95% CI 0.71 to 1.25), arterial oxygen saturation (SMD 0.63, 95% CI 0.25 to 1.02) and percutaneous oxygen (SMD 1.48, 95% CI 0.85 to 2.11). Breathing control had a detrimental effect on the work of breathing (SMD 1.06, 95% CI 0.52 to 1.60) and dyspnoea (SMD 1.47, 95% CI 0.88 to 2.05). Conclusion: When used as a sole intervention, there was a beneficial effect on outcomes related to the mechanism of breathing control as well as on short-term physiological outcomes. In people with severe respiratory disease, breathing control resulted in a detrimental effect on dyspnoea and work of breathing. There was no clear evidence of an effect on ventilation or long-term physiological outcomes related to gas exchange or the energy cost of breathing. Overall, evidence was satisfactory with studies demonstrating poor consistency, good generalisability, and satisfactory volume and quality. [ABSTRACT FROM AUTHOR]

Objectives. To compare mean angles of anterior pelvic tilt (APT) and variability of APT angles in elite cyclists and matched non-cyclists.Design. Observation, cross-sectional, matched pairs.Participants: Seventeen elite cyclists Australian Institute of Sport Track Cycling Squad (AISTCS) (23 +/- 4.2 years, 15 males) age and gender matched with 17 non-cyclists (23 +/- 4.1 years, 15 males).Setting: Laboratory within the University of South Australia. The APT was assessed in long-sitting position with chest as close to thighs as voluntarily possible and measured using a digital inclinometer over L5-S1 intervertebral space.Main outcome measures: APT in elite and non-cyclists. Unpaired t-tests and F-tests were used to analyze difference and variability of APT angles between groups with p

Decisions about curricular content in entry-level health professional programs are influenced by a variety of external and internal factors. However, little is known about how lecturers make decisions about the curricular content to be included or excluded from entry-level programs. This study aimed to explore the factors influencing such decision making regarding curricular content in entry-level Australian and New Zealand programs for physiotherapy, as well as how evidence-based practice (EBP) is integrated into the teaching and learning framework. Thirteen lecturers from 13 institutions (100% response rate) responsible for teaching a core part of physiotherapy practice, electrophysical agents, participated in a semistructured telephone interview. Decision making for curricular content involved an overall democratic process with the program team, but the day-to-day content was determined by the lecturer. Factors that lecturers reported as impacting on the choice of curriculum were current clinical practice, evidence, and accreditation or registration requirements. Thematic analysis of open-ended questions identified four main themes relating to the integration of the EBP paradigm within teaching: resource materials, use of broad definitions of evidence, inclusion of specific instructional strategies, and context of curriculum. Lecturers used a variety of research methodologies as a backdrop for the presentation of techniques and interventions that are used commonly in clinical practice despite limitations in the evidence base. The results highlighted tensions that exist when designing entry-level curricula with the need to prepare competent and safe practitioners while working within an EBP paradigm.

Attitudes and outcomes of sex education received by North American women are examined via an Internet survey (N = 1,400). Mean age was 19.5, with 24% reporting one or more unplanned pregnancies. Women were more satisfied with sex education from informal sources than from parents, schools, and physicians. Those receiving sex education from parents or schools reported fewer pregnancies and abortions. In school, women receiving a combination of contraceptive and abstinence education and those receiving primarily abstinence education were least likely to experience unplanned pregnancy. Religious identification was significantly related to unplanned pregnancy and type of sex education received from parents. These factors seem to play a significant role in reducing unplanned pregnancy and abortion. [ABSTRACT FROM AUTHOR]

The aim of this study was to determine the current curricula content of courses in electrophysical agents, and the factors that are perceived to impact on the choice of that content, in Australian and New Zealand entry-level physiotherapy programs. A semi-structured interview, including open and closed ended questions, was developed, piloted and conducted on 13 participants representing all 18 entry level physiotherapy programs (100 per cent response rate) in Australia and New Zealand between May and July 2004. Results of this semi-structured interview indicate that similarities exist between programs in the structure, assessment and content taught. Differences mainly occur in the content of practical electrophysical agents teaching with some modalities having a reduced emphasis and emerging forms of electrophysical agents, such as real time ultrasound for biofeedback, being included. The results of this study present a snap shot of the current status of electrophysical agents' curricula in entry level physiotherapy programs in Australia and New Zealand. This is the first published study to have evaluated curricular content in Australian and New Zealand entry level physiotherapy programs and as such provides a portrait, not only of current electrophysical agents' curricula, but also of program demographics in these two countries.

Despite racism being widespread and research evidence of racial disparities growing, those who lack the lived experience of racial oppression often find it difficult to acknowledge this specific phenomena due to in-group bias and social learning, among other reasons. The devaluing of this research topic within psychology and greater scientific skepticism around the construct continues to undermine research on racism and microaggressions. The science of microaggressions has advanced significantly in conceptual and theoretical clarity over the last 15 years. Many initial assumptions about the nature of microaggressions have since been found to be incorrect. This state of the science review addresses these concerns by reviewing the concept, validated measures, physical and mental health impacts, critiques and misinformation, recommended strategies and interventions, and clinical implications. We propose future research directions to help advance the scientific study of racial microaggressions., (Copyright © 2024 Association for Behavioral and Cognitive Therapies.

As clinical trials for psychedelics move into phase III in the USA, Europe must address its lag in integrating professional education around psychedelic-assisted therapy (PAT) and supporting psychedelic drug research. This paper evaluates the necessary frameworks for implementing PAT in Germany, emphasizing the nation's potential leadership role within the European Union. With Australia having already approved MDMA and psilocybin for mental health indications, the Ukrainian government exploring MDMA treatment for war-related PTSD, and initial clinical trials involving MDMA and LSD with patients in Switzerland which restarted the restricted medical use of these substances around 2014, the medical authorization of psychedelics in these countries establishes precedent showcasing both the promise and challenges of researching and implementing PAT in nations where the substances were formally scheduled as illicit substances. Key challenges include establishing rigorous standards for practitioner training, accessibility, and defining regulatory oversight. This paper focuses on the development of robust infrastructure in Germany, which will support the roll out of PAT, and details ethical considerations, training protocols, and governmental roles in the formulation of treatment frameworks. This approach aims not only to guide Germany in adopting PAT but also to influence broader European policy, ensuring that patients receive ethically sound and proficient care. The findings suggest pathways for Europe to reclaim its historical lead in psychiatric and therapeutic innovation., (© 2024. The Author(s).)

Background: Explanations provided by healthcare professionals contribute to patient beliefs. Little is known about how healthcare professionals explain chronic breathlessness to people living with this adverse sensation., Methods: A purpose-designed survey disseminated via newsletters of Australian professional associations (physiotherapy, respiratory medicine, palliative care). Respondents provided free-text responses for their usual explanation and concepts important to include, avoid, or perceived as difficult to understand by recipients. Content analysis coded free text into mutually exclusive categories with the proportion of respondents in each category reported., Results: Respondents ( n = 61) were predominantly clinicians (93%) who frequently (80% daily/weekly) conversed with patients about breathlessness. Frequent phrases included within usual explanations reflected breathlessness resulting from medical conditions (70% of respondents) and physiological mechanisms (44%) with foci ranging from multifactorial to single-mechanism origins. Management principles were important to include and phrases encouraging maladaptive beliefs were important to avoid. The most frequent difficult concept identified concerned inconsistent relationships between oxygenation and breathlessness. Where explanations included the term 'oxygen', a form of cognitive shortcut (heuristic) may contribute to erroneous beliefs., Conclusions: This study presents examples of health professional explanations for chronic breathlessness as a starting point for considering whether and how explanations could contribute to adaptive or maladaptive breathlessness beliefs of recipients.

This article addresses gaps in cognitive-behavioral therapy (CBT) when it comes to integrating racial issues that affect racialized patients' mental health. Traditional adaptations of CBT focused on social, religious, and linguistic challenges but neglected the critical aspects of interpersonal, institutional and systemic racism, internalized racism and complex racial trauma. This oversight has resulted in less effective outcomes for racialized individuals. The article proposes clear, applicable guidelines for clinicians to provide anti-racist CBT interventions. They cover clinical self-development, re-design the CBT triangular (thoughts, feelings, behaviors) theoretical framework, provide practical tools and tips to facilitate antiracist CBT interventions. Clinicians are encouraged to engage in self-assessment to understand their own racial biases and develop competencies to address racial issues and dynamics in therapy. CBT theoretical framework is re-envisioned to include environmental factors that impact the lives of racialized people, acknowledging the pervasive effects of racism on mental and physical health. The article also highlights the importance of creating a culturally safe therapeutic environment for racialized children, adolescents, and families, and emphasizes the need for specialized training to effectively serve these groups. The proposed guidelines aim to transform CBT practice, increase confidence of racialized individuals in mental health care, and ultimately decolonize CBT interventions., Competing Interests: Declaration of competing interest None, (Copyright © 2024 Elsevier B.V.

Polyethylene glycol (PEG) is a flexible, nontoxic polymer commonly used in biological and medical research, and it is generally regarded as biologically inert. PEG molecules of variable sizes are also used as crowding agents to mimic intracellular environments. A recent study with PEG crowders revealed decreased catalytic activity of Escherichia coli prolyl-tRNA synthetase (Ec ProRS), where the smaller molecular weight PEGs had the maximum impact. The molecular mechanism of the crowding effects of PEGs is not clearly understood. PEG may impact protein conformation and dynamics, thus its function. In the present study, the effects of PEG molecules of various molecular weights and concentrations on the conformation and dynamics of Ec ProRS were investigated using a combined experimental and computational approach including intrinsic tryptophan fluorescence spectroscopy, atomic force microscopy, and atomistic molecular dynamic simulations. Results of the present study suggest that lower molecular weight PEGs in the dilute regime have modest effects on the conformational dynamics of Ec ProRS but impact the catalytic function primarily via the excluded volume effect; they form large clusters blocking the active site pocket. In contrast, the larger molecular weight PEGs in dilute to semidilute regimes have a significant impact on the protein's conformational dynamics; they wrap on the protein surface through noncovalent interactions. Thus, lower-molecular-weight PEG molecules impact protein dynamics and function via crowding effects, whereas larger PEGs induce confinement effects. These results have implications for the development of inhibitors for protein targets in a crowded cellular environment.

Sexual orientation and gender identity/expression change efforts (SOGIECEs) are discredited practices that are associated with serious negative effects and incompatible with modern standards for clinical practice. Despite evidence linking SOGIECEs with serious iatrogenic effects, and despite support for LGBTQ+-affirmative care alternatives, SOGIECE practices persist. In the 1970s and 1980s, Behavior Therapy published articles testing and/or endorsing SOGIECEs, thereby contributing to their overall development, acceptance, and use. The Behavior Therapy Task Force on SOGIECEs was assembled to conduct a rigorous review of the SOGIECE articles published in Behavior Therapy and to decide whether, and what, formal action(s) should be taken on these articles. This report provides a detailed review of the historic SOGIECE literature published in Behavior Therapy and outlines the Task Force's deliberative and democratic processes resulting in actions to: (1) add prominent advisory information to k = 24 SOGIECE papers in the form of digital "black box" disclaimers that caution readers that the SOGIECE practices tested or described in these papers are inconsistent with modern standards, (2) offset organizational financial benefits from the publication of these papers, and (3) promote LGBTQ+-affirmative practices. SOGIECEs are not the only concerning practices across the field's history, and the pages of today's scientific journals include practices that will be at odds with tomorrow's moral standards and ethical guidelines. This report calls for precautionary measures and editorial safeguards to minimize the future likelihood and impact of problematic published scholarship, including the need to fully include those with relevant lived experiences in all aspects of clinical science and peer review., (Copyright © 2024 Association for Behavioral and Cognitive Therapies.

The Dimensional Obsessive-Compulsive Scale (DOCS) is widely used to measure obsessive-compulsive disorder (OCD) severity across four broad symptom dimensions (i.e., contamination, responsibility for harm, unacceptable thoughts, symmetry). Despite its proven utility, there is reason to suspect that the unacceptable thoughts subscale conflates different types of unacceptable thoughts that are meaningfully distinct from one another. In the current study, we first evaluated the psychometric properties of a newly developed DOCS violent and/or aggressive thoughts subscale. We then examined the factor structure, psychometric properties, and diagnostic sensitivity of a seven-factor version of the DOCS that includes the four original DOCS subscales and three more-specific versions of the unacceptable thoughts scale (i.e., sexually intrusive thoughts, violent and/or aggressive thoughts, and scrupulous or religious thoughts). The sample included 329 residential and intensive outpatients, the majority of which had a diagnosis of OCD (75.2%). The new unacceptable thoughts subscales demonstrated convergent and discriminant validity with unique associations between the subscales and depression, suicide, and perceived threat from emotions that were not present in the broader unacceptable thoughts subscale. The seven-factor version of the DOCS demonstrated slightly lower levels of diagnostic sensitivity than the original DOCS. Thus, the four-factor version of the DOCS is recommended for screening purposes. A score of 40 or higher on the seven-factor version of the DOCS best predicted a diagnosis of OCD. Overall, the three additional unacceptable thoughts subscales appear to be distinct factors that have potential value in research and clinical settings., (Copyright © 2024.

Racial stress and racial trauma refer to psychological, physiological, and behavioral responses to race-based threats and discriminatory experiences. This article reviews the evidence base regarding techniques for coping with racial stress and trauma. These techniques include self-care, self-compassion, social support, mindfulness, cognitive restructuring, cognitive defusion, identity-affirming practices and development of racial/ethnic identity, expressive writing, social action and activism, and psychedelics. These strategies have shown the potential to mitigate psychological symptoms and foster a sense of empowerment among individuals affected by racial stress and trauma. While the ultimate goal should undoubtedly be to address the root cause of racism, it is imperative to acknowledge that until then, implementing these strategies can effectively provide much-needed support for individuals affected by racism.

Introduction: Surgical oncology patients have a high symptom burden and increased risk of morbidity. The aim of palliative care is to evaluate and treat the patient in a holistic manner focusing on the unique attributes of each patient. This goal-concordant approach could help surgical patients cope with the stress and uncertainty that often accompany serious illness and surgery, improving overall outcomes. This qualitative analysis sought to explore whether unmet specialist palliative care or end-of-life needs exist in this population., Methods: Qualitative interviews were completed with a subset of participants in a randomized, controlled trial of a specialist palliative care intervention for patients undergoing abdominal oncologic surgery. The interview guide sought to elicit respondents' perceptions of palliative care and end-of-life needs perioperatively and postoperatively. Recurring themes were identified by two independent coders., Results: Analysis of 47 interview transcripts revealed few serious concerns about end-of-life issues, however appreciation for the supportive presence offered by palliative care was present. Among participants who received specialist palliative care, many found the intervention helpful, but few were able to articulate issues that the intervention improved., Conclusion: These findings suggest low levels of unmet palliative care needs among this population, which is consistent with the results of the parent trial. Targeting patients with a higher symptom burden perioperatively may allow for improved symptom management and better adherence to the treatment plan postoperatively, as well as be a more focused use of specialist palliative care clinicians' efforts., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Importance: As government agencies around the globe contemplate approval of the first psychedelic medicines, many questions remain about their ethical integration into mainstream medical practice., Objective: To identify key ethics and policy issues related to the eventual integration of psychedelic therapies into clinical practice., Evidence Review: From June 9 to 12, 2023, 27 individuals representing the perspectives of clinicians, researchers, Indigenous groups, industry, philanthropy, veterans, retreat facilitators, training programs, and bioethicists convened at the Banbury Center at Cold Spring Harbor Laboratory. Prior to the meeting, attendees submitted key ethics and policy issues for psychedelic medicine. Responses were categorized into 6 broad topics: research ethics issues; managing expectations and informed consent; therapeutic ethics; training, education, and licensure of practitioners; equity and access; and appropriate role of gatekeeping. Attendees with relevant expertise presented on each topic, followed by group discussion. Meeting organizers (A.L.M., I.G.C., D.S.) drafted a summary of the discussion and recommendations, noting points of consensus and disagreement, which were discussed and revised as a group., Findings: This consensus statement reports 20 points of consensus across 5 ethical issues (reparations and reciprocity, equity, and respect; informed consent; professional boundaries and physical touch; personal experience; and gatekeeping), with corresponding relevant actors who will be responsible for implementation. Areas for further research and deliberation are also identified., Conclusions and Relevance: This consensus statement focuses on the future of government-approved medical use of psychedelic medicines in the US and abroad. This is an incredibly exciting and hopeful moment, but it is critical that policymakers take seriously the challenges ahead.

Developmental stress, including low socioeconomic status (SES), can induce dysregulation of the hypothalamic-pituitary-adrenal axis and result in long-term changes in stress reactivity. Children in lower SES conditions often experience more stress than those in other SES groups. There are multiple model systems of early environmental stress (EES), one of which is reduced cage bedding. Here we tested the effects of both prenatal and lactational EES in rats on a range of long-term behavioral and cognitive outcomes. There were persistent reductions in body weight in the EES rats in both sexes. The behavioral results showed no effects on learning and memory using tests of spatial learning or cognitive flexibility in the Morris water maze, egocentric learning in the Cincinnati water maze, or working memory in the radial-arm maze. There were no effects on basic open-field activity, elevated zero-maze, or forced swim test, but EES rats had reduced time in the dark side of the light/dark test. When rats were drug challenged in the open-field with d-amphetamine or MK-801, there were no differential responses to d-amphetamine, but the EES group under responded compared with the drug-induced hyperactivity in the control group in both males and females. The objective was to establish a developmental stress model that induced cognitive deficits and to the extent that this method did not cause such effects it was not the model we sought. However, the data showed several long-term effects of EES, including the reduced response to the irreversible NMDA antagonist MK-801. This effect merits further investigation., Competing Interests: Declaration of competing interest The authors declare no conflict of interest connected to this research., (Copyright © 2024 Elsevier Inc.

Borrelia burgdorferi , the spirochetal agent of Lyme disease, utilizes a variety of strategies to evade and suppress the host immune response, which enables it to chronically persist in the host. The resulting immune response is characterized by unusually strong IgM production and a lack of long-term protective immunity. Previous studies in mice have shown that infection with B. burgdorferi also broadly suppresses host antibody responses against unrelated antigens. Here, we show that mice infected with B. burgdorferi and concomitantly immunized with recombinant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein had an abrogated antibody response to the immunization. To further define how long this humoral immune suppression lasts, mice were immunized at 2, 4, and 6 weeks post-infection. Suppression of host antibody production against the SARS-CoV-2 spike protein peaked at 2 weeks post-infection but continued for all timepoints measured. Antibody responses against the SARS-CoV-2 spike protein were also assessed following antibiotic treatment to determine whether this immune suppression persists or resolves following clearance of B. burgdorferi . Host antibody production against the SARS-CoV-2 spike protein returned to baseline following antibiotic treatment; however, anti-SARS-CoV-2 IgM remained high, comparable to levels found in B. burgdorferi -infected but untreated mice. Thus, our data demonstrate restored IgG responses following antibiotic treatment but persistently elevated IgM levels, indicating lingering effects of B. burgdorferi infection on the immune system following treatment., Competing Interests: The authors declare no conflict of interest.

Pre-mRNA splicing is a precise regulated process and is crucial for system development and homeostasis maintenance. Mutations in spliceosomal components have been found in various hematopoietic malignancies (HMs) and have been considered as oncogenic derivers of HMs. However, the role of spliceosomal components in normal and malignant hematopoiesis remains largely unknown. Pre-mRNA processing factor 31 (PRPF31) is a constitutive spliceosomal component, which mutations are associated with autosomal dominant retinitis pigmentosa. PRPF31 was found to be mutated in several HMs, but the function of PRPF31 in normal hematopoiesis has not been explored. In our previous study, we generated a prpf31 knockout (KO) zebrafish line and reported that Prpf31 regulates the survival and differentiation of retinal progenitor cells by modulating the alternative splicing of genes involved in mitosis and DNA repair. In this study, by using the prpf31 KO zebrafish line, we discovered that prpf31 KO zebrafish exhibited severe defects in hematopoietic stem and progenitor cell (HSPC) expansion and its sequentially differentiated lineages. Immunofluorescence results showed that Prpf31-deficient HSPCs underwent malformed mitosis and M phase arrest during HSPC expansion. Transcriptome analysis and experimental validations revealed that Prpf31 deficiency extensively perturbed the alternative splicing of mitosis-related genes. Collectively, our findings elucidate a previously undescribed role for Prpf31 in HSPC expansion, through regulating the alternative splicing of mitosis-related genes., Competing Interests: Conflict of interest The authors declare that they have no conflicts of interest with the contents of this article., (Copyright © 2024 The Authors.
