Exposure-response analyses of efzofitimod in patients with pulmonary sarcoidosis.

Background: Preliminary evidence for efficacy in pulmonary sarcoidosis has been shown for efzofitimod. Here we present supportive evidence of efficacy based on an exposure-response analysis. Methods: Data from two studies (Phase 1, N = 24, single dose in healthy volunteers, and Phase 1b/2a, N = 25, multiple doses over 24 weeks in participants with pulmonary sarcoidosis) were used to build a population pharmacokinetic model. Using this model, the relationship between efzofitimod exposure and three prespecified efficacy parameters [mean daily oral corticosteroid (OCS) dose, percent-predicted forced vital capacity (ppFVC) and King's Sarcoidosis Questionnaire-Lung (KSQ-Lung) score] was explored. Linear regression described the relationship of efzofitimod exposure and OCS reduction, ppFVC and KSQ-Lung score. Logistic regression related efzofitimod exposure to the probability of achieving a minimal clinically important difference for ppFVC and KSQ-Lung score. Due to the small study size, trends (not statistical significance) in relationships are reported. Results: In patients with pulmonary sarcoidosis, as efzofitimod exposure increased, the mean daily OCS dose decreased, and ppFVC and KSQ-Lung score improved over baseline. The slope for all the endpoints by both linear and logistic regression showed an improving trend with increased exposure. Conclusion: These preliminary findings of a positive exposure-response across multiple efficacy endpoints support the claim that proof of concept has been established for the use of efzofitimod in pulmonary sarcoidosis.

Feedback of aggregate patient-reported outcomes (PROs) data to clinicians and hospital end users: findings from an Australian codesign workshop process.

OBJECTIVES: Patient-reported outcomes (PROs) are increasingly used to measure the patient's perspective of their outcomes following healthcare interventions. The aim of this study was to determine the preferred formats for reporting service-level PROs data to clinicians, researchers and managers to support greater utility of these data to improve healthcare and patient outcomes. SETTING: Healthcare professionals receiving PRO data feedback at the health service level. PARTICIPANTS: An interdisciplinary Project Working Group comprised of clinicians participated in three workshops to codesign reporting templates of summarised PRO data (modified Rankin Scale, EuroQol Five Dimension Descriptive System, EuroQol Visual Analogue Scale and Hospital Anxiety and Depression Scale) using a modified Delphi process. An electronic survey was then distributed to short list the preferred templates among a broad sample of clinical end users. A final workshop was undertaken with the Project Working Group to review results and reach consensus on the final templates. PRIMARY AND SECONDARY OUTCOME MEASURES: The recommendation of preferred PRO summary data feedback templates and guiding principles for reporting aggregate PRO data to clinicians was the primary outcome. A secondary outcome was the identification of perceived barriers and enablers to the use of PRO data in hospitals. For each outcome measure, quantitative and qualitative data were summarised. RESULTS: 31 Working Group members (19 stroke, 2 psychology, 1 pharmacy, 9 researchers) participated in the workshops, where 25/55 templates were shortlisted for wider assessment. The survey was completed by 114 end users. Strongest preferences were identified for bar charts (37/82 votes, 45%) and stacked bar charts (37/91 votes, 41%). At the final workshop, recommendations to enhance communication of PROs data for comparing health service performance were made including tailoring feedback to professional roles and use of case-mix adjustment to ensure fair comparisons. CONCLUSIONS: Our research provides guidance on PROs reporting for optimising data interpretation and comparing hospital performance.

Risk of intracranial hemorrhage with direct oral anticoagulants vs low molecular weight heparin in glioblastoma: A retrospective cohort study.

BACKGROUND: Glioblastoma (GBM) is associated with a high incidence of venous thromboembolism (VTE), but there are little data to guide anticoagulation in patients with GBM, in whom the risks of VTE must be balanced against the risk of intracranial hemorrhage (ICH). METHODS: We performed a single-institution retrospective cohort study of patients with GBM diagnosed with VTE from 2014 to 2021 who were treated with low molecular weight heparin (LMWH) or a direct oral anticoagulant (DOAC). The incidence of ICH was compared between the LMWH and DOAC groups. The primary outcome was clinically relevant ICH within the first 30 days of anticoagulation, defined as any ICH that was fatal, symptomatic, required surgical intervention, and/or led to cessation of anticoagulation. Secondary outcomes included clinically relevant ICH within 6 months, fatal ICH within 30 days and 6 months, and any bleeding within 30 days and 6 months. RESULTS: One hundred twenty-one patients were identified in the cohort for 30-day outcome analyses (DOAC, n = 33; LMWH, n = 88). For 6-month outcome analyses, the cohort included only patients who were maintained on their initial anticoagulant (DOAC, n = 32; LMWH, n = 75). The incidence of clinically relevant ICH at 30 days was 0% in the DOAC group and 9% in the LMWH group (P = .11). The cumulative incidence of clinically relevant ICH at 6 months was 0% in the DOAC group and 24% in the LMWH group (P = .001), with 4 fatal ICHs in the LMWH group. CONCLUSIONS: DOACs are associated with a lower incidence of clinically relevant ICH in patients with GBM-associated VTE compared to LMWH.

Patient preferences using telehealth during the COVID-19 pandemic in four Victorian tertiary hospital services.

BACKGROUND: The Coronavirus disease 2019 (COVID-19) pandemic has had a major impact on healthcare services with many changes to telehealth care delivery. More information is needed about the patient perspective of telehealth in hospital services and the potential costs and benefits for patients. AIM: To measure patients' evaluation of telehealth, preferences for telehealth versus in-person appointments, and potential cost savings by patient characteristics. METHODS: A cross-sectional online survey (including patient and appointment characteristics, telehealth evaluation, preferences for care and costs) of adult patients using video telehealth in four metropolitan tertiary hospital services in Melbourne, Victoria. RESULTS: A total of 1045 patients (median age 44 years; interquartile range 29-59) participated with an overall response rate of 9.2%. For 98.7% patients, telehealth was convenient, 96.4% stated that it saved time, 95.9% found telehealth acceptable to receive care and 97.0% found that telehealth improved their access to care. Most (62.6%) preferred in-person consultations, although 86.9% agreed that telehealth was equivalent to an in-person consultation. Those in regional and rural areas were less likely to prefer in-person consultations. Patients attending for medical reasons were less likely to prefer in-person consultation compared with patients with surgical reasons. Patient preference to telehealth was independent of level of education, appointment type, self-rated health status and socio economic status. Patients saved an average of A$120.9 (standard deviation A$93.0) per appointment, with greater cost savings for patients from low and middle socio economic areas and regional or rural areas. CONCLUSION: Telehealth video consultations were largely evaluated positively with most patients considering the service to be as good as in-person. Understanding patient preference is critical to consider when implementing telehealth as mainstream across hospital health services.

Serious Illness Communication Practices in Glioblastoma: An Institutional Perspective.

Background: Early, high-quality advance care planning discussions are essential for supporting goal-concordant care among glioblastoma (GBM) patients. Objective: Using mixed methods, we sought to characterize current serious illness (SI) communication practices at our institution. Methods: The electronic medical records of 240 deceased GBM patients cared for at the Abramson Cancer Center in Philadelphia, PA between 2017 and 2019 were systematically reviewed for documented SI conversations about four domains: prognosis, goals, end-of-life planning, and code status. Patient outcomes and SI conversation characteristics were analyzed using descriptive statistics. Standardized interviews about GBM care were held with five clinicians. Interview transcripts were analyzed using grounded-theory coding to identify emergent themes. Results: Nearly all patients (96%) had at least one documented SI conversation (median: 4, interquartile range [IQR] 2-7), mostly outpatient with medical oncology physicians. Median timing of first SI conversation was 360 days before death. SI conversations were not significantly associated with patient outcomes, including inpatient death and hospice enrollment. Seven themes emerged from clinician interviews: balancing hope and reality, anticipatory guidance, neglect of the "big picture," need for earlier conversations, care coordination, the role of clinical expertise, and communication training. Conclusion: SI conversations were documented early and often in our sample, but their quality was difficult to assess. Contrary to our quantitative findings, interviewees reported that SI conversations were late, infrequent, inadequate, and fragmented across specialties, failing to explore critical issues such as prognosis and functional decline.

Reflective practice facilitation within occupational therapy supervision processes: A mixed method study.

INTRODUCTION: Supervisors of occupational therapists play a key role facilitating reflective practice with their supervisees. Through reflective practice, supervisees can optimise their skills in professional reasoning and decision making. The aim of this study was to describe to what degree reflective practice is facilitated within occupational therapy supervision processes. METHODS: A mixed methods study design was used, collecting data via online surveys and focus groups. Quantitative data were initially analysed using descriptive statistics. Qualitative and quantitative data were then thematically analysed to identify hindering and enabling mechanisms to reflective practice facilitation. RESULTS: Eighteen supervisees and 17 supervising occupational therapists completed the surveys and 14 supervisors participated in a focus group. Half of the supervisees reported that reflective practice was facilitated through supervision only "rarely" or "sometimes." A hindering mechanism to reflective practice facilitation was the awareness of reflective practice models. Enabling mechanisms for reflective practice facilitation included understanding the benefits of reflective practice; recognising the attributes of a reflective practice practitioner; setting up an optimal supervision environment; and flexibly facilitating reflective practice. CONCLUSION: Findings suggest that reflective practice is not always regularly facilitated through supervision. This may limit opportunities for supervisees to optimise the development of their professional reasoning and clinical skills in the early stages of their careers.

Learned pacing for adults with chronic pain: A randomised controlled trial feasibility study.

INTRODUCTION: Chronic pain can significantly impact on an individual's occupational performance and quality of life. Pacing is a pain management strategy regularly used in occupational therapy practice; however, evidence for its effectiveness has not been established. OBJECTIVES: To determine the feasibility of a future randomised controlled trial to investigate the effectiveness of a learned pacing intervention on occupational performance and satisfaction for adults with chronic pain. METHODS: A randomised controlled trial feasibility study was conducted with participants randomly assigned to a learned pacing intervention or a waitlist control group. The primary outcome measure was the Canadian Occupational Performance Measure. RESULTS: One hundred and twenty-eight people were screened for eligibility over 36 weeks, with 74 people invited to participate. Twelve were randomly assigned, eight to the learned pacing group and four to the control group. Those receiving the learned pacing intervention had clinically important changes in occupational performance and occupational satisfaction. Participants in the waitlist control group also had clinically important changes in occupational satisfaction. The method design was deemed feasible; however, several improvements would increase the rate of participant recruitment and reduce attrition. Recruitment from multiple sites is required to obtain an adequate sample size of 60. CONCLUSION: Undertaking a future randomised controlled trial is feasible and warranted to establish the effectiveness of a learned pacing intervention on occupational performance and satisfaction for adults with chronic pain.

Effectiveness of Pacing as a Learned Strategy for People With Chronic Pain: A Systematic Review.

IMPORTANCE: Pacing is a key pain management strategy used by occupational therapy practitioners when working with people with chronic pain. However, there is a paucity of evidence and a lack of consensus regarding the effectiveness of pacing as a pain management strategy for people with chronic pain. OBJECTIVE: To evaluate the evidence for the effectiveness of pacing as a learned strategy for people with chronic pain. DATA SOURCES: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to undertake a systematic review. Six databases were searched in March 2016 for randomized controlled trials (RCTs). Combinations of keywords and MeSH terms were used as search terms. STUDY SELECTION AND DATA COLLECTION: We sought intervention studies that included participants using pacing as a strategy. Studies were assessed for eligibility on the basis of predetermined criteria. Of the 2,820 articles located, 7 RCTs met inclusion criteria. FINDINGS: Pacing does not reduce the severity of pain or alter psychological traits; however, it can assist in lessening joint stiffness and the interference of fatigue and in decreasing the variability of physical activity. CONCLUSIONS AND RELEVANCE: Current evidence supports the delivery of a learned pacing intervention to reduce the interference of fatigue, reduce joint stiffness, and decrease physical activity variability but does not support the use of learned pacing to reduce pain severity. Future research should investigate the effectiveness of pacing as a pain management strategy within the International Classification of Functioning, Disability and Health domains of activity and participation. WHAT THIS ARTICLE ADDS: This systematic review examines existing research on pacing as a learned intervention strategy. The findings will support the clinical reasoning of occupational therapy practitioners, to determine when a learned pacing strategy is indicated, and considerations for how it may be delivered.

Bidirectional activity-dependent regulation of neuronal ion channel phosphorylation.

Activity-dependent dephosphorylation of neuronal Kv2.1 channels yields hyperpolarizing shifts in their voltage-dependent activation and homoeostatic suppression of neuronal excitability. We recently identified 16 phosphorylation sites that modulate Kv2.1 function. Here, we show that in mammalian neurons, compared with other regulated sites, such as serine (S)563, phosphorylation at S603 is supersensitive to calcineurin-mediated dephosphorylation in response to kainate-induced seizures in vivo, and brief glutamate stimulation of cultured hippocampal neurons. In vitro calcineurin digestion shows that supersensitivity of S603 dephosphorylation is an inherent property of Kv2.1. Conversely, suppression of neuronal activity by anesthetic in vivo causes hyperphosphorylation at S603 but not S563. Distinct regulation of individual phosphorylation sites allows for graded and bidirectional homeostatic regulation of Kv2.1 function. S603 phosphorylation represents a sensitive bidirectional biosensor of neuronal activity.
