Plastics in the environment have moved from an “eye-sore” to a public health threat. Hospitals are one of the biggest users of single-use plastics, and there is growing literature looking at not only plastics in the environment but health care’s overall contribution to its growth.
Methods
This study was a retrospective review at a 411-bed level II trauma hospital over 47 months pre and post the last wave of COVID-19 affecting this hospital. Deidentified data were gathered: daily census in the emergency department, hospital census, and corresponding number of admitted COVID-19 patients. Additionally, for the same time frame, personal protective equipment (PPE) supply purchases and gross tonnage of nonhazardous refuse were obtained.
Results
There was a large increase in PPE purchased without a significant change in gross tonnage of weight of trash.
Conclusions
PPE is incredibly important to protect health care workers. However, single-use plastic is not sustainable for the environment or public health. Understanding the full effect of the pandemic on hospital waste production is critically important as health care institutions focus on strategies to decrease their carbon footprint and increase positive impacts on public health and the environment.
In RISE, TV46000 once monthly (q1m) or once every 2 months (q2m) significantly extended time to impending schizophrenia relapse. The current study (SHINE, NCT03893825) evaluated the long-term safety, tolerability, and effect of TV46000.
Methods
Patients completing RISE without relapse (rollover) or newly recruited (de novo) were eligible. The de novo and placebo rollover cohorts were randomized 1:1 to q1m or q2m for ≤56 weeks; the TV46000 rollover cohort continued assigned regimen. Exploratory efficacy endpoints included time to impending relapse and patient centered outcomes (PCOs) including Schizophrenia Quality of Life Scale (SQLS).
Results
334 patients were randomized and received TV46000 q1m (n=172) or q2m (n=162), for 202.3 patient-years [PY] of TV-46000 treatment. Treatment-emergent adverse events (AEs) reported for ≥5% of patients were: overall–injection site pain (event rate/100 PY, n [%]; 23.23, 16 [5%]); de novo (n=109)–injection site pain (56.10, 11 [10%]), injection site nodule (16.03, 6 [6%]), blood creatine phosphokinase increased (16.03, 8 [7%]), urinary tract infection (10.69, 7 [6%]); placebo rollover (n=53)–tremor (18.50, 5 [9%]); TV46000 rollover (n=172)–headache (7.97, n=8 [5%]). Serious AEs reported for ≥2 patients were worsening schizophrenia and hyperglycemia. Kaplan– Meier estimates for remaining relapse-free at week 56 were 0.98 (2% risk; q1m) and 0.88 (12%; q2m). SQLS improved for q1m (least-squares mean change [SE], − 2.16 [0.98]) and q2m (− 0.43 [0.98]); other PCOs (5Level EuroQoL 5Dimensions Questionnaire, Personal and Social Performance Scale, Drug Attitudes Inventory 10-item version) remained stable.
Conclusions
TV-46000 had a favorable long-term benefit–risk profile in patients with schizophrenia.
The prevalence of schizophrenia is relatively low, yet increasing globally, and the disorder imparts a substantial burden of disease on both individuals and health systems. With regard to schizophrenia treatments, including long-acting injectable antipsychotics (LAIs), social media listening provides a unique source of insight into the experiences and perceptions of healthcare professionals (HCPs), patients, and caregivers who live with and manage this disorder daily.
Objective
To gain insight into HCP and patient/caregiver perceptions of LAIs for the treatment of schizophrenia.
Methods
Publicly available online conversations in global English about LAIs for schizophrenia from May 2, 2022, to May 2, 2023, were analyzed. Posts were collected using customized search strings from social media analysis tools, including Talkwalker and Meltwater. Online forums, such as Reddit, were the main source for patient/caregiver conversations. Conversations among HCPs were examined using publicly available posts from Twitter about schizophrenia/LAIs. Random samples of posts on forums (100) and Twitter (100) were coded for primary topic, author type (patient, caregiver, or HCP), sentiment toward LAIs, and signs of LAI hesitancy. Additional topics in posts, such as barriers and benefits to LAI use, were also examined.
Results
In the analyzed samples, some differences were observed between patients/caregivers (mostly patients) and HCPs (mostly psychiatrists) in lexicon, focus, and perspective. The most common terms for LAIs among patients/caregivers were “injection” or “shot,” while HCPs used the terms “LAIs” or “injectables.” The most frequent primary topic among patients/caregivers was treatment regimen, including impact of symptoms and side effects on quality of life. HCPs focused on drug efficacy, including broader health outcomes such as relapse, hospitalization, adherence, and mortality. Patients/caregivers expressed fewer positive sentiments (11% of posts) and more negative sentiments (35%) than HCPs (34% positive, 14% negative). Both groups noted reduced relapse and improved adherence among the top treatment benefits. Barriers to LAI use commonly cited by patients/caregivers included side effects and lack of effect on negative symptoms, while common barriers cited by HCPs included patient access/cost and limited knowledge around best prescribing practices. Treatment comparisons and/or switching were more commonly mentioned among patients/caregivers (51%) than HCPs (30%), suggesting a greater interest in optimizing treatment among patients. Patients/caregivers often compared individual LAIs with oral antipsychotics (OAs) or different LAIs, whereas it was more typical for HCPs to compare LAIs with OAs than to distinguish between different LAIs.
Conclusions
Based on social media posts, patients/caregivers and HCPs had different primary treatment goals/concerns and generally used different lexicons, which may affect communication. Overall, HCPs were more positive and less negative toward LAIs than patients/caregivers. Top benefits noted (relapse and adherence) were similar between groups, while top treatment barriers differed. These differences highlight the need to improve communication between patients/caregivers and HCPs in order to increase treatment satisfaction and potentially improve treatment outcomes.
Long-acting injectable antipsychotics (LAIs) reduce relapses in schizophrenia; however, most healthcare professionals (HCPs) reserve LAIs for nonadherence to oral antipsychotics (OAs) or severe disease.
Methods
US HCPs were surveyed regarding attitudes and perceptions toward LAIs for schizophrenia and LAI selection preferences. Respondents were grouped by LAI use (high [≥31% of patients using LAIs], low [≤14% using LAIs]; mid not analyzed) and archetype based on response to, “Which of the following best fits the current way you view your use of [LAIs] for your patients with schizophrenia?” (see responses below).
Results
Respondents (106 high, 130 low LAI use) were distributed across early LAI use (n=123), severity-reserved (n=88), adherence-reserved (n=113), and LAI-hesitant (n=56) archetypes.
Across all groups, HCPs estimated OA nonadherence in their practice (21%– 32%) to be lower than for patients nationwide (50%– 56%). Overall, 27% were dissatisfied with their LAI:OA use ratio, most thinking their OA use was too high. In all groups, side effects/tolerability was ranked as most important when choosing an LAI and “preference for the molecule” was ranked least important. Overall, 71%– 77% of HCPs were somewhat/much more likely to use a particular LAI based on multiple injection site options, small/on par needle, and price, and 63%– 82% of HCPs were somewhat/much more likely to select an LAI dosed once monthly or less often compared with an LAI dosed once every 2 weeks (8%). HCPs with high LAI use or early LAI use archetype were more likely to disagree that managing patients with schizophrenia increased their stress (64% and 63% vs 27%-45%, P<.05 each) and/or left them feeling “burned out” (77% and 79% vs 50%– 64%, P<.05 each).
Compared with other groups, greater proportions with high LAI use or early LAI use archetype consistently read new LAI publications (18% and 19% vs 0%– 5%, P<.01) and were confident in key aspects of LAI treatment (ie, dosing, managing side effects, access; 67%– 74% and 59%– 70% vs 11%– 57%, P<.05 each).
HCPs with low LAI use estimated the proportion of patients who initially refuse LAIs to be higher (mean, 55%) than those with low LAI use (44%, P<.01); there were no differences among archetypes (49%– 54%). HCPs with high LAI use or early LAI use archetype were more likely to “use any means necessary to ensure that a patient is on an LAI” vs other groups (44% and 51% vs 5%– 22%, P<.01 each) or had used guardianship to assist with treatment (70% and 69% vs 32%– 56%, P<.05 each); greater proportions with high LAI use or early LAI use archetype strongly agreed it was “worth [their] time to resolve issues with the insurance company” (42% and 45% vs 16%– 30%, P<.05 each) and were confident they would be able to do so (23% and 20% vs 2%– 11%, P<.05 each). Greater proportions of HCPs with early LAI use archetype vs the severity-reserved archetype strongly agreed that they attempt to determine the patient’s/caregiver’s preferred role before involving them (43% vs 27%, P<.05) and encourage them to participate (72% vs 57%, P<.05) in shared decision-making.
Conclusions
Comparing HCPs with high LAI use or early LAI use archetype vs other groups, multiple factors (eg, attitudes, preferences, training, knowledge base) combine to influence LAI use. These results highlight considerations for developing educational materials to increase LAI use in this population.
Healthcare professionals (HCPs) face unique challenges when managing patients with schizophrenia. Educational initiatives targeting common clinical dilemmas encountered by clinicians, including partial or nonadherence, may alleviate knowledge gaps and clarify the role of long-acting injectable antipsychotic agents (LAIs) in treating this population.
Methods
4 experts in schizophrenia management used empirical evidence to identify 11 key clinical dilemmas where LAIs may be useful. These experts then developed a heuristic, educational tool (S.C.O.P.E.™: Schizophrenia Clinical Outcome Scenarios and Patient-Provider Engagement) based on empirical evidence and expert opinion for clinicians to use when encountering similar scenarios to optimize schizophrenia care.
Results
S.C.O.P.E.™ is a freely-available resource comprising an interactive digital platform providing educational materials for HCPs involved in continued care for patients with schizophrenia. S.C.O.P.E.™ provides HCPs with considerations in common clinical scenarios met in inpatient and outpatient settings, as well as questions to consider when patients present to the emergency department. The potential usefulness of LAIs is explored in each scenario. Clinical education videos prepare nurse practitioners, social workers, and case managers to address patient concerns and communicate the benefits of LAI treatment. S.C.O.P.E.™ will not replace clinical judgment, guidelines, or continuing medical education, and is not a platform for recording patient-level data, nor intended for payer negotiations or access-related questions by HCPs.
Conclusions
S.C.O.P.E.™ is an educational tool for HCPs to use alongside standard psychiatric evaluations to improve understanding of how to manage common clinical dilemmas when treating patients with schizophrenia and the role of LAIs in schizophrenia management.
Healthcare professionals (HCPs) face unique challenges when managing patients with schizophrenia. Educational initiatives targeting common clinical dilemmas encountered by clinicians, such as unfamiliarity with prescribing information for long-acting injectable antipsychotics (LAIs), may assist clinicians when treating patients with schizophrenia.
Methods
Four experts in schizophrenia management used empirical evidence to identify 11 key clinical dilemmas where LAIs may be useful. These experts then developed a heuristic, educational tool (S.C.O.P.E.™: Schizophrenia Clinical Outcome Scenarios and Patient-Provider Engagement) based on empirical evidence and expert opinion for clinicians to use when encountering similar scenarios to optimize schizophrenia care. S.C.O.P.E.™ also includes supportive elements such as an LAI selector.
Results
S.C.O.P.E.™ is a freely available resource comprising an interactive digital platform providing educational materials for HCPs involved in continued care for patients with schizophrenia. To acquaint HCPs with characteristics of common LAIs used in schizophrenia treatment, S.C.O.P.E.™ offers a selector that filters LAIs by approved indication(s), initiation regimen, reconstitution, dosing strengths and frequency, injection volumes and routes, and supply and storage information based on approved product labels. The LAI selector does not provide LAI safety and efficacy data, so HCPs should visit individual product websites for this information. Therefore, S.C.O.P.E.™ will not replace clinical judgment, guidelines, or continuing medical education, and is not a platform for recording patient-level data, nor intended for payer negotiations or access-related questions by HCPs.
Conclusions
S.C.O.P.E.™ is an educational tool for HCPs to use alongside standard psychiatric evaluations to improve understanding of how to manage common clinical dilemmas when treating patients with schizophrenia, the role of LAIs in schizophrenia management, and the product characteristics of available LAIs.
The diffusion of digital health interventions (DHIs) requires agreement on a minimum information framework to define them. The ISPOR Digital Health (DH) Special Interest Group (SIG) developed the PICOTS-ComTeC framework based upon a systematic review and a Delphi study. It is an enriched version of the traditional PICOTS widely adopted in health technology assessment (HTA). ComTeC stands for communication, technology, and context.
Methods
The PICOTS-ComTeC is based upon a review that included the Shannon–Weaver model of communication, AHRQ Quality Measures, technology, geography, and the World Health Organization classification of DHIs followed by a Delphi panel. The development process adhered to the EQUATOR guidelines. The PICOTS-ComTeC aims to be a flexible and versatile tool tested on different DHIs. The results of the testing are discussed from the HTA perspective considering the tool’s additional value, utility for and applicability to HTA. The additional value is strictly linked to the actual need for a dedicated PICOTS for DHIs and its implications for HTA assessments of DHIs.
Results
The PICOTS-ComTeC was tested internally and externally to the ISPOR DH-SIG on four DHIs for breast cancer surgery/management/patient education, one DHI for obesity, and one DHI for patients with heart failure. The testing phase demonstrated the level of detail required to use the tool, hitherto available evidence to cover all domains, and opened up discussion on implications of the PICOTS-ComTeC framework for HTA related activities (i.e., scoping, literature search, comparator selection). It emerged that there is a diffuse lack of homogeneity and details when DHIs are defined in the literature with significant implications for conducting appropriate HTAs.
Conclusions
The diffuse adoption of the PICOTS-ComTeC for patient-facing DHIs will promote a greater level of detail in order to define homogenous DHI groups. The implications for HTA range from the definition of relevant research questions to the selection of the most appropriate comparator so that assessments are geared to fulfill the needs of decision-makers.
University students often make less healthful dietary choices whilst at university however, do not typically receive advice and support to help them eat more healthily(1,2). A tool which could be provided to students to promote more favourable dietary behaviours is the eNutri web-based app which includes a food frequency questionnaire (FFQ) and delivers automated personalised nutrition advice (PNA) and a diet quality score (DQS) consisting of 11 food/nutrient components(3). The PNA includes scores and general advice for each component and, for the user’s three lowest scoring components, recommends which foods to eat more/less frequently to improve their DQS. As part of a 4-week intervention study, we aimed to explore the perceptions of the eNutri PNA in UK university students.
As part of this intervention, 14 students from the Universities of Reading and Hertfordshire completed the eNutri FFQ and received their PNA. At the end of the study, they rated how much they agreed with statements about the perceived value and benefit (if any) of the eNutri PNA tool, on a 6-point scale ranging from strongly disagree to strongly agree. The percentage of respondents reported is the total number who responded “somewhat agree”, “agree”, or “strongly agree” to each statement.
Of the 14 students, 79% were female with a mean age of 25y (range = 18-37y) and mean BMI of 24.7kg/m2 (range = 19.4-31.9kg/m2). At baseline, the average importance of a healthy diet to the participants (n = 13) was rated at 7.2 out of 10 (with 0 being ‘not important at all’ and 10 being ‘very important’). In total, 57% of respondents indicated that they felt they ‘were eating a healthier diet because of the eNutri advice received’ and only 14% reported that ‘the advice did not motivate them to make changes to their diet’. Furthermore, 64% of respondents indicated that the ‘eNutri PNA gave them confidence in their ability to make changes to their diet’ and that it ‘supported them to do so’. Half of the students agreed that ‘they would want to use eNutri long term to track their progress and receive regular PNA’. In addition, 79% agreed that ‘eNutri should be offered to all university students to help them make healthier food choices’, and that if eNutri was offered to them for free by their university, ‘it would be a valuable student benefit’ and they ‘would want to use it again’.
In general, university students indicated the eNutri PNA tool supported them to eat healthier and providing access to the wider student population would be beneficial to encourage healthy eating at university. These findings along with the quantitative data from the PNA intervention which is currently being analysed will support the development of larger, suitably-powered studies to confirm these findings.
In New York, organic production of muskmelon (Cucumis melo) and other cucurbits is limited by pests, diseases, and weeds. Among the most important pests are striped (Acalymma vittatum) and spotted (Diabrotica undecimpunctata howardi) cucumber beetles that cause damage through feeding. Cucumber beetles also transmit the bacterium, Erwinia tracheiphila, the causal agent of bacterial wilt. Mesotunnels are a modified row cover system consisting of nylon mesh netting supported by hoops approximately 1-m high, which have potential for incorporation into organic muskmelon production systems. The netting is an effective barrier for pests and insect-vectored diseases and also prevents insect-mediated pollination and in-season weed management in inter-bed areas. Two separate experiments were conducted in 2021 and 2022 to: (a) evaluate mesotunnels for organic muskmelon production and methods to control weeds in inter-bed areas (experiment 1), and (b) evaluate selected pollination treatments for integration into a mesotunnel production system (experiment 2). In experiment 1, there were four treatments: (i) landscape fabric in the inter-bed area with a mesotunnel, (ii) landscape fabric in the inter-bed area without a mesotunnel, and a (iii) ryegrass/white clover in the inter-bed area with a mesotunnel; or (iv) ryegrass cover crop in the inter-bed area with a mesotunnel. In experiment 1, mesotunnels significantly reduced cucumber beetle populations and bacterial wilt epidemic progress but did not affect the incidence of the foliar diseases, powdery mildew, or Alternaria leaf spot. In the mesotunnel and non-covered treatments, landscape fabric, applied for weed control between beds, resulted in greater fruit weight and more marketable fruit compared to mesotunnels with cover crops in the inter-bed area. In experiment 2, treatments were on/off/on (removal of netting during flowering followed by replacement), open ends (open ends during flowering), and a closed mesotunnel (with the insertion of a commercial bumblebee hive). Although the on/off/on treatment increased cucumber beetle populations and bacterial wilt epidemic progress compared to the open ends and closed treatments, it conferred significant yield benefits in both years. These findings emphasize the importance of systems-level analysis for evaluating the suitability of mesotunnels in organic muskmelon production.
Paediatric patients with heart failure requiring ventricular assist devices are at heightened risk of neurologic injury and psychosocial adjustment challenges, resulting in a need for neurodevelopmental and psychosocial support following device placement. Through a descriptive survey developed in collaboration by the Advanced Cardiac Therapies Improving Outcomes Network and the Cardiac Neurodevelopmental Outcome Collaborative, the present study aimed to characterise current neurodevelopmental and psychosocial care practices for paediatric patients with ventricular assist devices.
Method:
Members of both learning networks developed a 25-item electronic survey assessing neurodevelopmental and psychosocial care practices specific to paediatric ventricular assist device patients. The survey was sent to Advanced Cardiac Therapies Improving Outcomes Network site primary investigators and co-primary investigators via email.
Results:
Of the 63 eligible sites contacted, responses were received from 24 unique North and South American cardiology centres. Access to neurodevelopmental providers, referral practices, and family neurodevelopmental education varied across sites. Inpatient neurodevelopmental care consults were available at many centres, as were inpatient family support services. Over half of heart centres had outpatient neurodevelopmental testing and individual psychotherapy services available to patients with ventricular assist devices, though few centres had outpatient group psychotherapy (12.5%) or parent support groups (16.7%) available. Barriers to inpatient and outpatient neurodevelopmental care included limited access to neurodevelopmental providers and parent/provider focus on the child’s medical status.
Conclusions:
Paediatric patients with ventricular assist devices often have access to neurodevelopmental providers in the inpatient setting, though supports vary by centre. Strengthening family neurodevelopmental education, referral processes, and family-centred psychosocial services may improve current neurodevelopmental/psychosocial care for paediatric ventricular assist device patients.
To examine feasibility, acceptability, and preliminary effectiveness of a novel group-based telemedicine psychoeducation programme aimed at supporting psychological well-being among adolescents with Fontan-palliated CHD.
Study design:
A 5-week telemedicine psychoeducation group-based programme (WE BEAT) was developed for adolescents (N = 20; 13–18 years) with Fontan-palliated CHD aimed at improving resiliency and psychological well-being. Outcome measures included surveys of resilience (Connor–Davidson Resilience Scale), benefit finding (Benefit/Burden Scale for Children), depression, anxiety, peer relationships, and life satisfaction (National Institutes of Health Patient-Reported Outcomes Measurement Information System scales). Within-subject changes in these outcomes were compared pre- to post-intervention using Cohen’s d effect size. In addition, acceptability in the form of satisfaction measures and qualitative feedback was assessed.
Results:
Among eligible patients reached, 68% expressed interest in study participation. Of those consented, 77% have been scheduled for a group programme to date with 87% programme completion. Twenty adolescents (mean age 16.1 ± SD 1.6 years) participated across five WE BEAT group cohorts (range: 3–6 participants per group). The majority (80%) attended 4–5 sessions in the 5-session programme, and the median programme rating was a 9 out of 10 (10 = most favourable rating). Following WE BEAT participation, resiliency (d = 0.44) and perceptions of purpose in life increased (d = 0.26), while depressive symptoms reduced (d = 0.36). No other changes in assessed outcome measures were noted.
Conclusions:
These findings provide preliminary support that a group-based, telemedicine delivered psychoeducation programme to support psychological well-being among adolescents with CHD is feasible, acceptable, and effective. Future directions include examining intervention effects across diverse centres, populations, and implementation methods.
The aim of this study was to explore the perspectives of older medicinal cannabis consumers and those advising them on older Canadians’ experiences accessing cannabis and information about it, as well as how stigma may influence their experiences. A concurrent triangulation mixed methods design was used. The design was qualitatively driven and involved conducting semi-structured interviews with older adults and advisors and developing a survey for older adults. We used a Qualitative Descriptive approach for the analysis of qualitative data and descriptive statistics for quantitative survey data. Findings demonstrate that many older adults are accessing information about cannabis for medical purposes from retailers, either because they are reticent to talk to their healthcare professionals or were rebuffed when bringing up the subject. We recommend cannabis education be required for healthcare professionals working with older persons and that future research examines their perspectives on medicinal cannabis and older adults.
In response to the COVID-19 pandemic, we rapidly implemented a plasma coordination center, within two months, to support transfusion for two outpatient randomized controlled trials. The center design was based on an investigational drug services model and a Food and Drug Administration-compliant database to manage blood product inventory and trial safety.
Methods:
A core investigational team adapted a cloud-based platform to randomize patient assignments and track inventory distribution of control plasma and high-titer COVID-19 convalescent plasma of different blood groups from 29 donor collection centers directly to blood banks serving 26 transfusion sites.
Results:
We performed 1,351 transfusions in 16 months. The transparency of the digital inventory at each site was critical to facilitate qualification, randomization, and overnight shipments of blood group-compatible plasma for transfusions into trial participants. While inventory challenges were heightened with COVID-19 convalescent plasma, the cloud-based system, and the flexible approach of the plasma coordination center staff across the blood bank network enabled decentralized procurement and distribution of investigational products to maintain inventory thresholds and overcome local supply chain restraints at the sites.
Conclusion:
The rapid creation of a plasma coordination center for outpatient transfusions is infrequent in the academic setting. Distributing more than 3,100 plasma units to blood banks charged with managing investigational inventory across the U.S. in a decentralized manner posed operational and regulatory challenges while providing opportunities for the plasma coordination center to contribute to research of global importance. This program can serve as a template in subsequent public health emergencies.
Understanding variations in knowledge and attitudes of psychiatrists to psilocybin therapy is important for the collective discourse about the potential impact on clinical practice and public health in Ireland.
Methods:
A 28-item questionnaire was designed based on previous studies and distributed to psychiatrists in Ireland via online mailing lists and at in-person academic events.
Results:
151 psychiatrists completed the questionnaire (73.3% were under 40 years of age, 76.0% were trainees, and 49.0% were female). In the total sample, 81.5% agreed that psilocybin therapy shows promise in the treatment of psychiatric disorders and 86.8% supported funding research, 86.8% would be willing to refer a patient if it was licensed and indicated, and 78.1% would consider the treatment for themselves, if indicated. Conversely, 6.6% agreed that psilocybin therapy was unsafe even under medical supervision, and 21.9% thought it was potentially addictive. 15.9% of the total sample reported at least one concern including, lack of robust evidence, long-term effectiveness, superiority to current interventions, potential harmful effects, cost and accessibility, and impartiality. Less than half of respondents felt knowledgeable (40.0%) and 9.9% felt adequately prepared to participate in psilocybin therapy. Consultant psychiatrists trended towards less optimism for a potential role in bipolar depression and emotionally unstable personality disorder compared to trainee psychiatrists.
Conclusion:
Overall psychiatrists in Ireland held positive attitudes towards psilocybin therapy. However, there was a lack of knowledge evident. Addressing the knowledge gap and aligning with the best available evidence will be key if psychedelic therapy is to prevail in a clinical setting.
During 2016–2022, Medicare part D beneficiaries filled 8,674,460 clotrimazole-betamethasone dipropionate prescriptions. Annual rates were stable (30.9 prescriptions/1,000 beneficiary-years in 2022, enough for one in every 33 beneficiaries). Diagnostic testing was infrequent, particularly among internal medicine, family medicine, and general practitioners, suggesting potential opportunities to improve diagnostic and prescribing practices.
Diagnostic criteria for major depressive disorder allow for heterogeneous symptom profiles but genetic analysis of major depressive symptoms has the potential to identify clinical and etiological subtypes. There are several challenges to integrating symptom data from genetically informative cohorts, such as sample size differences between clinical and community cohorts and various patterns of missing data.
Methods
We conducted genome-wide association studies of major depressive symptoms in three cohorts that were enriched for participants with a diagnosis of depression (Psychiatric Genomics Consortium, Australian Genetics of Depression Study, Generation Scotland) and three community cohorts who were not recruited on the basis of diagnosis (Avon Longitudinal Study of Parents and Children, Estonian Biobank, and UK Biobank). We fit a series of confirmatory factor models with factors that accounted for how symptom data was sampled and then compared alternative models with different symptom factors.
Results
The best fitting model had a distinct factor for Appetite/Weight symptoms and an additional measurement factor that accounted for the skip-structure in community cohorts (use of Depression and Anhedonia as gating symptoms).
Conclusion
The results show the importance of assessing the directionality of symptoms (such as hypersomnia versus insomnia) and of accounting for study and measurement design when meta-analyzing genetic association data.
The centrifugal mirror confinement scheme incorporates supersonic rotation of a plasma into a magnetic mirror device. This concept has been shown experimentally to drastically decrease parallel losses and increase plasma stability as compared with prior axisymmetric mirrors. MCTrans++ is a dimensionless (0-D) scoping tool which rapidly models experimental operating points in the Centrifugal Mirror Fusion Experiment (CMFX) at the University of Maryland. In the low-collisionality regime, parallel losses can be modelled analytically. A confining potential is set up that is partially ambipolar and partially centrifugal. Due to the stabilizing effects of flow shear, the perpendicular losses can be modelled as classical. Radiation losses such as bremsstrahlung and cyclotron emission are taken into account. A neutrals model is included, and, in some circumstances, charge-exchange losses are found to exceed all other loss mechanisms. We use the SUNDIALS ARKODE library to solve the underlying equations of this model; the resulting software is suitable for scanning large parameter spaces, and can also be used to model time-dependent phenomena such as a capacitive discharge. MCTrans++ has been used to verify results from prior centrifugal mirrors, create an experimental plan for CMFX and find configurations for future reactor-scale fusion devices.
The study of psychological well-being and related resilient outcomes is of increasing focus in cardiovascular research. Despite the critical importance of psychological well-being and related resilient outcomes in promoting optimal cardiac health, there have been very few psychological interventions directed towards children with heart disease. This paper describes the development and theoretical framework of the WE BEAT Wellbeing Education Program, a group-based psychoeducation and coping skills training intervention designed to improve psychological well-being and resilience in adolescents with paediatric heart disease.
Methods:
Program development was informed by patient and family needs and input gathered via large, international survey methods as well as qualitative investigation, a theoretical framework, and related resilience intervention research.
Results:
An overview of the WE BEAT intervention components and structure of the programme is provided.
Conclusions:
The WE BEAT Wellbeing Education Program was developed as one of the first resiliency-focused interventions in paediatric heart disease with an overall objective to foster positive psychological well-being and resilient outcomes through a health promotion and prevention lens in an accessible format while providing access to safe, peer-to-peer community building. Feasibility pilot results are forthcoming. Future directions include mobile app-based delivery and larger-scale efficacy and implementation trials.
OBJECTIVES/GOALS: In this study, we aim to report the role of porins and blaCTX-M β-lactamases among Escherichia coli and Klebsiella pneumoniae, focusing on emerging carbapenem resistant Enterobacterales (CRE) subtypes, including non-carbapenemase producing Enterobacterales (NCPE) and ertapenem-resistant but meropenem-susceptible (ErMs) strains. METHODS/STUDY POPULATION: Whole genome sequencing was conducted on 76 carbapenem-resistant isolates across 5 hospitals in San Antonio, U.S. Among these, NCP isolates accounted for the majority of CRE (41/76). Identification and antimicrobial susceptibility testing (AST) results were collected from the clinical charts. Repeat speciation was determined through whole genome sequencing (WGS) analysis and repeat AST, performed with microdilution or ETEST®. Minimum inhibitory concentrations (MIC) were consistent with Clinical and Laboratory Standards Institute (CLSI M100, ED33). WGS and qPCR were used to characterize the resistome of all clinical CRE subtypes, while western blotting and liquid chromatography with tandem mass spectrometry (LC-MS-MS) were used to determine porin expression and carbapenem hydrolysis, respectively. RESULTS/ANTICIPATED RESULTS: blaCTX-Mwas found to be most prevalent among NCP isolates (p = 0.02). LC-MS/MS analysis of carbapenem hydrolysis revealed that blaCTX-M-mediated carbapenem hydrolysis, indicating the need to reappraise the term, “non-carbapenemase (NCP)®” for quantitatively uncharacterized CRE strains harboring blaCTX-M. Susceptibility results showed that 56% of all NCPE isolates had an ErMs phenotype (NCPE vs. CPE, p < 0.001), with E. coli driving the phenotype (E. coli vs. K. pneumoniae, p < 0.001). ErMs strains carrying blaCTX-M, had 4-fold more copies of blaCTX-M than ceftriaxone-resistant but ertapenem-susceptible isolates (3.7 v. 0.9, p < 0.001). Immunoblot analysis demonstrated the absence of OmpC expression in NCP-ErMs E. coli, with 92% of strains lacking full contig coverage ofompC. DISCUSSION/SIGNIFICANCE: Overall, this work provides evidence of a collaborative effort between blaCTX-M and OmpC in NCP strains that confer resistance to ertapenem but not meropenem. Clinically, CRE subtypes are not readily appreciated, potentially leading to mismanagement of CRE infected patients. A greater focus on optimal treatments for CRE subtypes is needed.
OBJECTIVES/GOALS: Mayo Clinic (MC) launched the Rapid Activation Trial (RAT) pilot program in 2022 to expedite the activation of high priority and high impact clinical trials. The objective was to develop a process for rapid activation through robust screening, prioritization, and project management (PM) support. METHODS/STUDY POPULATION: The project team developed a robust screening and approval process for the RAT program using a combination of an objective scoring tool (based on strategic priorities) and a diverse selection committee to screen and approve eligible trials. Sponsors had to commit to RAT program timelines. Upon approval, trials were prioritized at the highest level within each business unit involved in the activation process. The number of trials approved annually were limited to 8 to manage volume and facilitate seamless prioritization with an activation timeline goal of 6 weeks. Project management support for RAT program focused on financial, regulatory, logistical, and operational elements to open trials expeditiously. RESULTS/ANTICIPATED RESULTS: In 2022, thirteen (13) applications were received and eight (8) were approved by the RAT selection committee. The approved trials activated with a median open to enrollment time of 6.4 weeks from engaging with business units. They also aligned closely with organization’s strategic priorities, including but not limited to Investigator Initiated Trials, Multi-Site protocols, IND/IDE protocols, Rare Diseases, First in Human and Commercialization potential trials. PI and study team feedback was positive. In 2023, the RAT program was renewed due to the pilot’s significant success in 2022. The goal is to open 10 trials and 5 have been activated by the end of Q3, 2023 with a median timeline of 6 weeks. DISCUSSION/SIGNIFICANCE: Rapid activation of high priority and high impact clinical trials enables an organization to strategically prioritize and open complex clinical trials. This allows the delivery of innovative, timely cures to patients in an expeditious timeline.
