RESUMO
BACKGROUND: Preventing or delaying the onset of psychosis requires identification of those at risk for developing psychosis. For predictive purposes, the prodrome - a constellation of symptoms which may occur before the onset of psychosis - has been increasingly recognized as having utility. However, it is unclear what proportion of patients experience a prodrome or how this varies based on the multiple definitions used. METHODS: We conducted a systematic review and meta-analysis of studies of patients with psychosis with the objective of determining the proportion of patients who experienced a prodrome prior to psychosis onset. Inclusion criteria included a consistent prodrome definition and reporting the proportion of patients who experienced a prodrome. We excluded studies of only patients with a prodrome or solely substance-induced psychosis, qualitative studies without prevalence data, conference abstracts, and case reports/case series. We searched Ovid MEDLINE, Embase (Ovid), APA PsycInfo (Ovid), Web of Science Core Collection (Clarivate), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, APA PsycBooks (Ovid), ProQuest Dissertation & Thesis, on March 3, 2021. Studies were assessed for quality using the Critical Appraisal Checklist for Prevalence Studies. Narrative synthesis and proportion meta-analysis were used to estimate prodrome prevalence. I2 and predictive interval were used to assess heterogeneity. Subgroup analyses were used to probe sources of heterogeneity. (PROSPERO ID: CRD42021239797). RESULTS: Seventy-one articles were included, representing 13,774 patients. Studies varied significantly in terms of methodology and prodrome definition used. The random effects proportion meta-analysis estimate for prodrome prevalence was 78.3% (95% CI = 72.8-83.2); heterogeneity was high (I2 97.98% [95% CI = 97.71-98.22]); and the prediction interval was wide (95% PI = 0.411-0.936). There were no meaningful differences in prevalence between grouped prodrome definitions, and subgroup analyses failed to reveal a consistent source of heterogeneity. CONCLUSIONS: This is the first meta-analysis on the prevalence of a prodrome prior to the onset of first episode psychosis. The majority of patients (78.3%) were found to have experienced a prodrome prior to psychosis onset. However, findings are highly heterogenous across study and no definitive source of heterogeneity was found despite extensive subgroup analyses. As most studies were retrospective in nature, recall bias likely affects these results. While the large majority of patients with psychosis experience a prodrome in some form, it is unclear if the remainder of patients experience no prodrome, or if ascertainment methods employed in the studies were not sensitive to their experiences. Given widespread investment in indicated prevention of psychosis through prospective identification and intervention during the prodrome, a resolution of this question as well as a consensus definition of the prodrome is much needed in order to effectively direct and organize services, and may be accomplished through novel, densely sampled and phenotyped prospective cohort studies that aim for representative sampling across multiple settings.

OBJECTIVES: To demonstrate how health technology assessment (HTA) methods can be used to support Medicare's price negotiations for apixaban and rivaroxaban. METHODS: Following the statutory outline of evidence that will be considered by Medicare, we conducted a systematic literature review, network meta-analyses (NMAs), and decision analyses to evaluate the health outcomes and costs associated with apixaban and rivaroxaban compared to warfarin and dabigatran for patients with non-valvular atrial fibrillation. Our methods inform discussions about the therapeutic impact of apixaban and rivaroxaban and suggest price premiums above their therapeutic alternatives over a range of cost-effectiveness thresholds. RESULTS: NMAs found apixaban resulted in a lower risk of major bleeding compared to warfarin and dabigatran, and a lower risk of stroke/systemic embolism compared to warfarin, but not compared to dabigatran. Rivaroxaban resulted in a lower risk of stroke/systemic embolism versus warfarin but not dabigatran, and there was no difference in major bleeding. Decision-analytic modeling of apixaban suggested annual price premiums up to $4,350 above the price of warfarin and up to $530 above the price for dabigatran at cost-effectiveness thresholds up to $200,000 per equal value of life years gained. Analyses of rivaroxaban showed an annual price premium of up to $3,920 above warfarin, and no premium above that paid for dabigatran. CONCLUSIONS: Although HTA is typically performed near the time of regulatory approval, with modifications, we produced comparative clinical and relative cost-effectiveness findings to help guide negotiations on a "fair" price for drugs on the market for over a decade.
RESUMO
OBJECTIVES: This study aimed to evaluate the diversity of clinical trials informing assessments conducted by the Institute for Clinical and Economic Review. METHODS: This was a cross-sectional study of pivotal trials included in completed Institute for Clinical and Economic Review assessments over 5 years (2017-2021). Representation of racial/ethnic minority groups, females, and older adults was compared with the disease-specific and US population, using a relative representation cutoff of 0.8 for adequate representation. RESULTS: A total of 208 trials, evaluating 112 interventions for 31 unique conditions, were examined. Race/ethnicity data were inconsistently reported. The median participant-to-disease representative ratio (PDRR) for Blacks/African Americans (0.43 [interquartile range (IQR) 0.24-0.75]), American Indians/Alaska Natives (0.37 [IQR 0.09-0.77]), and Hispanics/Latinos (0.79 [IQR 0.30-1.22]) were below the adequate representation cutoff. In contrast, Whites (1.06 [IQR 0.92-1.2]), Asians (1.71 [IQR 0.50-3.75]), and Native Hawaiian/Other Pacific Islanders (1.61 [IQR 0.77-2.81]) were adequately represented. Findings were similar when compared with the US Census, except for Native Hawaiian/Pacific Islanders, which was substantially worse. Relative to all trials, a higher proportion of US-based trials adequately represented Blacks/African Americans (61% vs 23%, P < .0001) and Hispanics/Latinos (68% vs 50%; P = .047), but a lower proportion adequately represented Asians (15% vs 67%, P < .0001). Females were adequately represented in 74% of trials (PDRR: 1.02 [IQR 0.79-1.14]). Nevertheless, older adults were adequately represented in only 20% of trials (PDRR: 0.30 [IQR 0.13-0.64]). CONCLUSIONS: The representation of racial/ethnic minorities and older adults was inadequate. Efforts are needed to enhance the diversity of clinical trials. Standardized and transparent evaluation of trial diversity should be part of the health technology assessment process.

Cannabis use is common in first-episode psychosis (FEP) but evidence is mixed about the extent to which cannabis use predicts symptoms and functional outcomes among those who seek treatment. This study sought to characterize cannabis use patterns and examine the relationship with clinical outcomes, including interactions with early intervention services (EIS). Data were drawn from the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study including FEP individuals receiving treatment at sites randomized to provide either EIS (NAVIGATE) or community care (CC). Cannabis use was assessed monthly and symptom and functioning data were collected at baseline, 6, 12, 18, and 24 months. Among the 404 participants enrolled, 334 were classified into four cannabis use groups (consistent, sporadic, stopped, and never users) based on their use during the first year. Consistent and sporadic cannabis users were younger, whereas those who had stopped using were older. Sporadic users had the highest depression and the lowest functioning at baseline and improved less during treatment in negative emotions and intrapsychic foundations (e.g., motivation and sense of purpose) than non-users. However, sporadic users who received NAVIGATE improved more in overall symptoms and functioning than those who received CC. Consistent users did not tend to differ in their trajectories from non-users. Individuals with FEP who use cannabis sporadically showed less clinical improvement than non-users. However, EIS treatment reduced the negative effects of sporadic cannabis use on clinical outcomes. Those who use cannabis sporadically may have unique needs that require attention in EIS.

BACKGROUND: Poor clinical insight has been commonly reported in those with First Episode Psychosis (FEP) and thought to be influenced by a range of factors, including neurocognition and symptoms. Clinical insight may be compromised as a result of alterations in higher-level reflective processes, such as metacognitive ability and cognitive insight. AIMS: To explore whether metacognitive ability and cognitive insight are associated with clinical insight while controlling for IQ, depression, and symptoms in FEP. METHODS: 60 individuals with FEP completed measures for clinical insight, metacognitive ability, cognitive insight, positive and negative symptoms, depression, and IQ. RESULTS: Higher levels of metacognitive ability were associated with better clinical insight, even when controlling for IQ, depression, positive and negative symptoms, and medication. Integration subscale of metacognitive ability was most strongly associated with clinical insight. Cognitive insight was associated with clinical insight when controlling for covariates. However, when including metacognitive ability and cognitive insight in the predictive model, only metacognitive ability was significantly related to clinical insight. DISCUSSION: Metacognitive ability, specifically the ability to describe one's evolving mental state to provide a coherent narrative, was significantly related to clinical insight, independent of covariates, and may be a potentially important target for intervention in FEP.

BACKGROUND: Self-defining memories (SDMs) are important for identifying one's purpose in life, achieving goals, and overcoming challenging situations. Individual studies have demonstrated differences in the characteristics of SDMs between clinical and non-clinical populations. This systematic literature review aimed to summarise and compare SDM characteristics among those with mental, substance use, cognitive, neurodevelopmental, and physical health challenges. METHODS: Peer-reviewed English-language studies were included if they evaluated SDMs in these groups. RESULTS: Thirty-five studies (N = 3123) were included. SDM content across all clinical populations tended to focus on illness themes. SDMs were generally less specific and integrated in those with mental health or substance use disorders as compared to non-clinical populations. SDM specificity and integration findings were more mixed in those with cognitive, neurodevelopmental, and physical health challenges. CONCLUSIONS: Specific differences emerged between groups of individuals which may be related to illness characteristics, recovery trajectory, and individual differences in the ability to understand and process difficult life events.

BACKGROUND: Unusual experiences in Tulpamancer and Autonomous Sensory Meridian Response (ASMR) communities are generally positive and sought after, unlike hallucinations and delusions in clinical populations. Metacognition, the ability to reflect on self-referential experiences, may aid sense-making around unusual experiences, reducing distress. This study investigated group differences in hallucination-proneness, delusion-proneness, and metacognition in these communities compared to controls, and whether metacognition predicted unusual experiences. METHODS: 243 participants reporting ASMR, Tulpamancy, or neither, with no history of psychosis, took part in an online observational study. Participants completed the Beck Cognitive Insight Scale, Metacognitions Questionnaire-30, and Brief Core Schema Scales to capture metacognition. A Tulpamancer+ (reporting ASMR) group was identified and included in analyses. ANCOVAs highlighted group differences in hallucination-proneness, with Tulpamancer+ scoring higher, and metacognitive beliefs, with Tulpamancers reporting lower metacognitive belief endorsement. There were no group differences in delusion-proneness, self-reflection, or self-schemas. Stepwise regression demonstrated metacognition does influence unusual experiences in the non-clinical population, and this influence varies across groups. CONCLUSIONS: In non-clinical populations, unusual sensory experiences are not associated with increased metacognitive beliefs, but having multiple unusual experiences is associated with higher hallucination-proneness. Results suggest improving metacognition in clinical groups may help reduce distress related to unusual sensory experiences.

Introduction: In several sub-fields of psychology, there has been a renewed focus on measurement practices. As far as we are aware, this has been absent in hallucinations research. Thus, we investigated (a) cross-study variation in how hallucinatory experiences are measured and (b) the reliability of measurements obtained using two tasks that are widely employed in hallucinations research.Method: In Study 1, we investigated to what extent there was variation in how the Launay-Slade Hallucination Scale (LSHS) has been used across 100 studies. In Study 2, we investigated the reliability of the measurements obtained through source monitoring and signal detection tasks, using data from four recent publications. Materials/data are available at doi: 10.17605/osf.io/d3gnk/.Results: In Study 1, we found substantial variation in how hallucinatory experiences were assessed using the LSHS and that descriptions of the LSHS were often incomplete in important ways. In Study 2, we reported a range of reliability estimates for the measurements obtained using source monitoring and signal discrimination tasks. Some measurements obtained using source monitoring tasks had unacceptably low levels of reliability.Conclusions: Our findings suggest that suboptimal measurement practices are common in hallucinations research and we suggest steps researchers could take to improve measurement practices.

To examine the feasibility, acceptability, and initial validity of using smartphone-based peer-supported ecological momentary assessment (EMA) as a tool to assess loneliness and functioning among adults with a serious mental illness diagnosis. Twenty-one adults with a diagnosis of a serious mental illness (i.e., schizophrenia, schizoaffective disorder, bipolar disorder, or treatment-refractory major depressive disorder) and at least one medical comorbidity (i.e., cardiovascular disease, obesity, diabetes, chronic obstructive pulmonary disease, hypertension, and/or high cholesterol) aged 18 years and older completed EMA surveys via smartphones once per day for 12-weeks. Nine peer support specialists prompted patients with SMI to complete the EMA surveys. Data were collected at baseline and 12-weeks. EMA acceptability (15.9%) was reported, and participants rated their experience with EMA methods positively. EMA responses were correlated with higher social support at 3 months. Higher levels of EMA-measured loneliness were significantly correlated with levels of social support, less hope, and less empowerment at 3 months. Lastly, those who contacted their peer specialist reported higher levels of loneliness and lower levels of functioning on that day suggesting that participants were able to use their peers for social support. Peer-supported EMA via smartphones is a feasible and acceptable data collection method among adults with SMI and appears to be a promising mobile tool to assess loneliness and functioning. These preliminary findings indicate EMA-measured loneliness and functioning are significantly predicted by baseline variables and such variables may impact engagement in EMA. EMA may contribute to future research examining the clinical utility of peer support specialists to alleviate feelings of loneliness and improve functioning.

Background: Social cognition, including emotion perception, is impaired in people with serious mental illnesses (SMI), and is associated with cognitive and community functioning. Cognitive remediation can improve neurocognition, but the impact on emotion perception has been less well studied. The current study aimed to evaluate the efficacy of a cognitive remediation programme in improving emotion perception.Methods: Thirty-seven people with SMI and a history of difficulties obtaining employment were randomised to either vocational rehabilitation only, or vocational rehabilitation combined with cognitive remediation. Participants were assessed at baseline and post-treatment on a neurocognitive battery, work history, and emotion perception.Results: The cognitive remediation group did not improve more than the vocational rehabilitation only group on either measure of emotion perception, despite significantly greater gains in cognitive functioning. Baseline emotion identification, but not discrimination, was significantly associated with cognition and work history.Conclusions: Despite associations between social and neurocognition, there was no evident transfer of cognitive gains to performance on measures of emotion perception. The findings, though limited by a small sample size, are important in expanding the research indicating that the effects of cognitive remediation tend to be limited to the specific cognitive domains targeted in the program.

Anomalous self-experiences have been described as a prerequisite for anomalous perceptual experiences. Later, these anomalous perceptual experiences may then be metacognitively appraised as distressing, maintaining these experiences and later leading to anomalous (delusional) beliefs. This model of anomalous events may potentially be driven by perceptual biases and metacognitive deficits. This cross-sectional study explored the association between perceptual biases, metacognition and anomalous self- and perceptual experiences and delusional beliefs in First Episode Psychosis (FEP) and a matched healthy control sample. Fifty-eight individuals with FEP and seventy-two healthy controls were included in the main analysis. Increased auditory perceptual biases were significantly associated with increased state and trait anomalous self-experiences, in particular alienation from surroundings and emotional numbing. No significant associations were found between metacognitive efficiency and anomalous experiences. These findings may be consistent with the minimal self-disturbance model of schizophrenia spectrum vulnerability, particularly with the hyperreflexivity concept.

Introduction The objective of this qualitative study was to assess healthcare providers' acceptability of an ongoing postpartum human papillomavirus (HPV) vaccination program in Southeast Texas and its integration into everyday clinical care. Methods In 2012, the Department of Obstetrics & Gynecology at the University of Texas Medical Branch (UTMB) began offering HPV vaccination as part of standard postpartum care to increase vaccination rates among young women in Galveston County. Initial vaccine doses were offered on the postpartum unit while subsequent doses were coordinated with postpartum and well-baby visits. Thirty months after project initiation, semi-structured interviews of physicians (n = 12) and nurses (n = 6) involved in postpartum and pediatric care at UTMB were conducted. Interview transcripts were analyzed using thematic analysis in Nvivo10. Results Overall, providers demonstrated "pro-vaccine" attitudes and stated the program was an effective strategy for vaccinating hard-to-reach women. Cancer prevention was the main perceived benefit while follow-up compliance was the primary perceived patient barrier. The initial challenges with integrating postpartum HPV vaccination included miscommunication between providers regarding vaccine orders and coordination issues with well-baby visits for follow-up doses. One novel finding was providers' beliefs that women's personal HPV vaccine practices may positively impact their decisions about later vaccinating their children against HPV. Providers' suggestions to improve the program included: enhancing postpartum HPV vaccine education for patients, offering more continuing education for providers, and increasing community awareness of HPV vaccination. Discussion These findings can help providers of postpartum care understand how to integrate postpartum HPV vaccination into their current practices and how to overcome perceived vaccination barriers.

OBJECTIVES: The topic of diversity in clinical trials is rising to the forefront of many conversations in evidence-based medicine, and efforts are being made to improve the diversity of clinical trials. However, there is little uniformity in the methods used to evaluate these efforts. In this article, we describe our Clinical trial Diversity Rating (CDR) framework and the development process, including the broader considerations for evaluating the demographic diversity of clinical trials and their implications, and demonstrate its use through an illustrative example. STUDY DESIGN AND SETTING: The development of the framework was a four-step process, including a scoping review, a cross-sectional study, creation of the tool, and integration of feedback from an advisory group. RESULTS: Our scoping review identified 110 publications that examined clinical trial diversity. Race/ethnicity, sex, and age were the most common characteristics evaluated. About 85% clearly defined the benchmark used for evaluation, but less than half (48%) used disease prevalence as the benchmark. Only 64% of studies defined what would be considered adequate representation. The cross-sectional study, which applied some of the approaches identified in the literature, helped to identify the complexities of evaluating multinational trials and certain demographic characteristics. Key decisions for the CDR framework, such as the demographic characteristics to be evaluated, the benchmark and thresholds for evaluation, and how these factors contribute to the overall rating of clinical trial diversity, were informed by the two earlier phases and feedback from an advisory group. CONCLUSION: The CDR framework provides an objective and transparent approach to evaluating clinical trial diversity. Groups such as Health Technology Assessment bodies, clinical trial regulators, policymakers, journal editors, and individual researchers can use this tool to examine, monitor, and improve diversity in clinical trials.

BACKGROUND: Hallucinations have been linked to failures in metacognitive reflection suggesting an association between hallucinations and overestimation of performance, although the cross-sectional findings are inconsistent. This inconsistency may relate to the fluctuating hallucinatory experiences that are not captured in cross-sectional studies. Ecological Momentary Assessment (EMA) captures in-the-moment experiences over time so can identify causal relationships between variables such as the associations between metacognition and hallucinatory experience in daily life and overcome problems in cross-sectional designs. METHODS: Participants (N = 41) experiencing daily hallucinations completed baseline questionnaires and smartphone surveys 7 times per day for 14 days. They were prompted to identify a task they would complete in the next 4 h and to make metacognitive predictions around the likelihood of completing the task, the difficulty of the task, and how well they would complete it (standard of completion). RESULTS: 76 % finished the 14-days of assessment with an average of 42.2 % survey completion. Less accurate metacognition was associated with more hallucinations, but less accurate likelihood and standard of completion was associated with fewer hallucinations. Using a cross-lagged analysis, metacognitive predictions around the likelihood of completion (p < .001) and standard of completion (p = .01) predicted hallucination intensity at the following timepoint, and metacognitive predictions regarding likelihood of completion (p = .02) predicted hallucination control at the following timepoint. DISCUSSION: Interventions that aim to improve metacognitive ability in-the-moment may serve to reduce the intensity and increase the control of hallucinations.

Cartilage tissue engineering aims to develop functional substitutes for treating cartilage defects and osteoarthritis. Traditional two-dimensional (2D) cell culture systems lack the complexity of native cartilage, leading to the development of 3D regenerative cartilage models. In this study, we developed a 3D model using Gelatin Methacryloyl (GelMA)-based hydrogels seeded with Y201 cells, a bone marrow mesenchymal stem cell line. The model investigated chondrogenic differentiation potential in response to Wnt3a stimulation within the GelMA scaffold and validated using known chondrogenic agonists. Y201 cells demonstrated suitability for the model, with increased proteoglycan content and upregulated chondrogenic marker expression under chondrogenic conditions. Wnt3a enhanced cell proliferation, indicating activation of the Wnt/ß-catenin pathway, which plays a role in cartilage development. GelMA hydrogels provided an optimal scaffold, supporting cell viability and proliferation. The 3D model exhibited consistent responses to chondrogenic agonists, with TGF-ß3 enhancing cartilage-specific extracellular matrix (ECM) production and chondrogenic differentiation. The combination of Wnt3a and TGF-ß3 showed synergistic effects, promoting chondrogenic differentiation and ECM production. This study presents a 3D regenerative cartilage model with potential for investigating cartilage biology, disease mechanisms, and drug screening. The model provides insights into complex cartilage regeneration mechanisms and offers a platform for developing therapeutic approaches for cartilage repair and osteoarthritis treatment.

BACKGROUND: Hospital infection control policies protect patients and healthcare workers (HCWs) and limit the spread of pathogens, but adherence to COVID-19 guidance varies. We examined hospital HCWs' enactment of social distancing and use of personal protective equipment (PPE) during the COVID-19 pandemic, factors influencing these behaviours, and acceptability and feasibility of strategies to increase social distancing. METHODS: An online, cross-sectional survey (n = 86) and semi-structured interviews (n = 22) with HCWs in two English hospitals during the first wave of the COVID-19 pandemic (May-December 2020). The Capability, Opportunity, Motivation (COM-B) model of behaviour change underpinned survey and topic guide questions. Spearman Rho correlations examined associations between COM-B domains and behaviours. Interviews were analysed using inductive and deductive thematic analysis. Potential strategies to improve social distancing were selected using the Behaviour Change Wheel and discussed in a stakeholder workshop (n = 8 participants). RESULTS: Social distancing enactment was low, with 85% of participants reporting very frequently or always being in close contact with others in communal areas. PPE use was high (88% very frequently or always using PPE in typical working day). Social distancing was associated with Physical Opportunity (e.g., size of physical space), Psychological Capability (e.g., clarity of guidance), and Social Opportunity (e.g., support from managers). Use of PPE was associated with Psychological Capability (e.g., training), Physical Opportunity (e.g., availability), Social Opportunity (e.g., impact on interactions with patients), and Reflective Motivation (e.g., beliefs that PPE is effective). Local champions and team competition were viewed as feasible strategies to improve social distancing. CONCLUSIONS: It is valuable to understand and compare the drivers of individual protective behaviours; when faced with the same level of perceived threat, PPE use was high whereas social distancing was rarely enacted. Identified influences represent targets for intervention strategies in response to future infectious disease outbreaks.

BACKGROUND: Metacognition refers to appraising one's thoughts and behaviours. Deficits in metacognition are associated with psychosis-spectrum experiences, such as hallucinations and delusions, in both clinical and non-clinical populations. Assessments of metacognitive function and abilities in clinical populations often vary in administration duration, and subjectivity of scores. This study investigates associations between different measures of metacognition and their prediction of psychosis spectrum experiences using objective and self-report measures in a cross-sectional study of psychosis-spectrum disorder (PSD) participants and controls. METHOD: Twenty-three individuals with PSD and forty-four controls were recruited online and completed in-the-moment objective ratings of metacognitive accuracy (meta-Dots Task), and retrospective self-report of metacognitive self-reflection (Beck Cognitive Insight Scale) and abilities (Metacognition Self-Assessment Scale). RESULTS: There were group differences in self-reported metacognition, with PSD participants having lower scores of metacognitive ability, but no differences in self-reflectiveness or objective metacognitive accuracy. In the PSD group, only self-reported metacognitive ability was associated with and predicted distress about, and conviction in, delusional thoughts. CONCLUSIONS: The findings demonstrate group differences in some self-reported, but not objective, measures of metacognition, and highlight that prediction of PSD experiences depends on the metacognitive construct being measured, and the type of measurement used.
