Abstract Introduction Cannabidiol has been shown to exert significant anti-inflammatory effects and has demonstrated efficacy in murine models of autoimmune myocarditis, pericarditis, and heart failure. The ARCHER Study assessed whether a pharmaceutically produced cannabidiol formulation showed beneficial effects on cardiac magnetic resonance (CMR) endpoints known to predict prognosis in this patient population. Methods In a multicentre international double-blind placebo-controlled phase 2 study, we randomly assigned 109 patients within 10 days of CMR confirmed diagnosis of acute myocarditis to 12 weeks of pharmaceutically produced oral cannabidiol (active) or placebo. Dose was titrated up to 10 mg/kg of body weight twice daily. Primary endpoints were the difference in extracellular volume (ECV) and global longitudinal strain (GLS) measured by CMR at week 12. Other CMR endpoints included left-ventricular ejection fraction (LVEF), LV mass, intracellular volume (ICV), LV end-diastolic and end-systolic volumes (LVEDV, LVESV), and left-atrial end-systolic volume (LAESV). Results All randomized patients (56 active/53 placebo) completed the study with no loss to follow-up. Study drug appeared safe and well tolerated. Baseline mean ECV 38.9 ± 10.9 ml, GLS −15.3 ± 3.6%, and LVEF 60.6 ± 9.9% were consistent with mild to moderate myocarditis and predominantly intact LV function. Week 12 mean ECV was 33.6 ml in the active group and 37.3 ml in the placebo group, a difference of −3.7 ml, confidence interval (CI): −7.4 to 0.1; P = .0538; GLS was −16.0% in the active group and −15.9% in the placebo group, difference of −0.1, CI: −1.2 to 1.1; P = .90. Left ventricular mass was significantly reduced in the active group at 121.1 g compared to placebo 130.3 g, a difference of −9.2, CI: −16.4 to −2.1; P = .0117. In terms of remodelling, LAESV was significantly reduced in the active group (−8.1 ml; P = .0376) while the reduction in LVEDV failed to reach significance (−7.4 ml; P = .098). Conclusion In mild-to-moderate acute myocarditis, treatment with pharmaceutically manufactured cannabidiol was not associated with a statistically significant change in myocardial ECV or GLS, although a trend towards reduction in ECV was observed. In addition, improvement in other potential markers of myocardial recovery, including a significant reduction in LV mass, was seen in the active treatment group. Further investigation of the therapeutic potential of this therapy in inflammatory cardiac conditions is warranted.

Abstract Background Bedaquiline, pretomanid, and linezolid with or without moxifloxacin (BPaL/M) are recommended oral 6-month treatment regimens for multidrug- or rifampin-resistant (MDR/RR) tuberculosis (TB). Since the US rollout of these regimens in 2019, the US Centers for Disease Control and Prevention (CDC) and partners have identified patients who failed or relapsed on these regimens. Methods Here, we report a case series of US patients with TB treated with BPaL/M-containing regimens, who experienced adverse outcomes during the period 2022‒2024, including drug resistance, relapse, and treatment failure. Results Clinical and public health outcomes were significant for US patients reported. There were 8 patients identified (n = 8). 5 (62.5%) were male, with a median age 57 years, 2 (25%) were previously treated for TB, and 8 (100%) presented with cavitary disease. This included a patient who died from infectious TB with acquired resistance after exposing over 100 healthcare workers, a waitress who was found to have highly infectious TB at the time of her relapse, and a son who contracted Mycobacterium tuberculosis (Mtb) with reduced activity to bedaquiline from his mother in a household transmission event. Conclusions These patients highlight consequences, both for the individual and public health, of relapse and treatment failure in real-life operational settings that may not be readily evident in well-controlled and well-resourced clinical trials. Despite the advent of shorter and better tolerated bedaquiline-based regimens, US clinicians continue to face challenges in managing drug-resistant TB. These data support the need for expert management of these patients beyond routine TB care, as well as the need for close monitoring and follow-up months after treatment completion.

Abstract Caregivers for people with neurodegenerative disease (PWNDs) often experience mental and physical health problems, especially when caring for PWNDs who have deficits in emotional functioning. We studied 65 PWNDs and their caregivers both during active caregiving and after caregiving had ended to determine: (a) how caregiver health changes after caregiving ends; and (b) whether PWNDs’ emotional functioning predicts these changes. PWND emotional functioning was assessed in the laboratory by measuring their generation of preparatory physiological activity (e.g., increased heart rate) to an upcoming emotional event (i.e., emotion eliciting films). Caregiver mental and physical health were measured using the Short-Form Health Survey (SF36) during active caregiving and again after caregiving had ended. Results indicated that, overall, caregivers reported increases in mental health, (t(36) = 2.58, p = .014, 95% CI [1.31, 10.93]) but decreases in physical health (t(36) = -2.35, p = .025, 95% CI [-7.26, -0.53]) across the two measurement periods. Using latent change score models, PWNDs’ preparatory physiological response impairments were associated with better caregiver mental health trajectories (β = -0.37, SE = 0.04, p = .003) such that smaller PWND preparatory responses predicted greater improvements in caregiver mental health (β = 9.92, SE = 2.84, p < .001). There was no association with changes in caregiver physical health. Smaller preparatory physiological responses in PWNDs may indicate diminished emotional responding, which is linked with lower caregiver mental health during active caregiving. Once caregiving ends, these caregivers may be most likely to “rebound” and show improvements in mental health.

Abstract As a group, family caregivers of people with dementia (PWDs) have substantially elevated levels of depression and anxiety, compared to same-aged non-caregiving adults. However, there is striking variation in mental health among individual caregivers. Previous research on predictors of the sources of these individual differences has focused on characteristics of individual caregivers and PWDs (rather than on the caregiver-PWD relationship), self-report measures (rather than behavioral measures), and negative emotion (rather than positive emotion). We examined 185 caregiver-PWD dyads who had an unrehearsed 10-minute conversation about an area of conflict in the laboratory. Video recordings were coded for Behavioral Indicators of Positivity Resonance (BIPR), which derives from Positivity Resonance Theory and assesses dyad-level behavioral expressions of positive affect, mutual warmth, and synchrony. Caregivers reported their level of depression, anxiety, and emotional well-being and PWDs underwent a comprehensive neurological and neuropsychological evaluation. Pearson’s correlations revealed that greater dyad-level BIPR was associated with caregivers’ higher emotional well-being (r(181) = .19, p = .008), lower depression (r(179) = -.17, p = .025), and lower anxiety (r(180) = -.15, p = .045). Regression analyses revealed that these associations were still obtained after controlling for caregiver age and sex and PWD dementia severity, cognitive impairment, and neuropsychiatric behavior (emotional well-being ß = .18, p = .012; depression ß = -.15, p = .039; anxiety ß = -.15, p = .044). Future studies should determine whether interventions that increase co-experienced positive emotions among caregiver-PWD dyads help buffer caregivers from adverse mental health consequences.

Background This study aimed to evaluate outcomes of different antibiotic durations in patients with severe diverticulitis. Methods Initial electronic medical record review identified 2437 adult patients who underwent sigmoid colectomy. Manual chart review identified 133 patients who underwent sigmoid resection and proximal diversion for Hinchey stage 3 or 4 diverticulitis. Patients who received a short antibiotic course (SAC, ≤5 days) were compared with those who received a long antibiotic course (LAC, >5 days). The primary composite outcome included superficial, incisional, organ-space infections or death within 30 days post procedure. Results A total of 53 SAC patients and 55 LAC patients were identified. The composite outcome occurred more frequently in LAC patients than in SAC patients (40% vs 15%; P = .005). Organ-space infection occurred more frequently in LAC patients than in SAC patients (31% vs 13%; P = .04). Conclusions Extended duration of antibiotics after adequate source control does not improve outcomes even in the setting of extensive intra-abdominal contamination.

ABSTRACT Introduction Metabolic dysfunction‐associated steatotic liver disease (MASLD) and steatohepatitis (MASH) represent a spectrum of liver conditions that can gradually progress to cirrhosis. Sodium‐glucose co‐transporter‐2 (SGLT‐2) inhibitors have shown benefits in reducing hepatic steatosis and liver‐related events in MASLD. This study aims to assess whether SGLT‐2 inhibitors are associated with a reduced risk of all‐cause mortality and disease‐specific outcomes in patients with MASH cirrhosis and type 2 diabetes (T2D). Methods A retrospective cohort study was performed using TriNetX. Patients with T2D and MASH cirrhosis on SGLT‐2 inhibitors were matched 1:1 with other glucose‐lowering drugs (oGLDs) based on demographics, comorbidities and medications. Primary outcomes included all‐cause mortality, hepatic decompensation and major adverse liver outcomes (MALO). Cox‐proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence interval (CI). Results A total of 51 427 patients with MASH cirrhosis and T2D were identified, of which 6833 (13.28%) were on SGLT‐2 inhibitors. Patients on SGLT‐2 inhibitors ( n = 6449, mean age 63.7 years, 52.9% female) were matched with 6449 individuals (mean age 63.9 years, 53.5% female) on oGLDs. The SGLT‐2 inhibitors cohort had statistically significantly lower risk of all‐cause mortality (HR: 0.58, 95% CI: 0.53–0.63), hepatic decompensation (HR: 0.85, 95% CI: 0.81–0.90) and MALO (HR: 0.88, 95% CI: 0.83–0.93). Conclusion SGLT‐2 inhibitors are associated with a reduced risk of all‐cause mortality in patients with MASH cirrhosis and T2DM, which may be partly attributable to a lower risk of hepatic decompensation and subsequent events. Further studies are warranted as SGLT‐2 inhibitors may serve as an adjunctive therapy for patients with MASH cirrhosis.

Abstract Background Prior studies of Alzheimer's disease (AD) biomarker disclosure have answered important questions about individuals’ experiences learning amyloid results. In comparison, the experiences of individuals performing AD biomarker disclosure have been under characterized. The present study examines the clinician experience disclosing amyloid positron emission tomography (PET) results within the Alzheimer's Disease Neuroimaging Initiative's ADNI‐4 study. Methods The ADNI‐4 longitudinal cohort study includes a pragmatic process for amyloid PET disclosure for participants across the cognitive spectrum. Disclosing clinicians complete a short questionnaire after each disclosure session, reporting on the visit length, the clinician's rating of participant and study partner understanding and emotional reactions, topics discussed, challenges, assessment of the visit overall, and any feedback about the process. Results Across the first 100 disclosures (48 cognitively normal, 35 Mild Cognitive Impairment (MCI), 17 dementia) in ADNI‐4, visits lasted an average of 29.4 minutes (SD 13.9, range 10‐90). Most cognitively impaired participants had a loved one present at the disclosure visit (dementia 94%, MCI 80%) but the majority of cognitively normal participants (73%) did not. Clinicians rated understanding of the result as adequate for all study partners and the vast majority (94%) of participants. Clinicians reported feeling “very confident” in their ability to assess readiness to receive result (70%), disclose (73%), and answer questions (77%). Clinicians rated all visits as “good” or better, with two‐thirds (65%) rated as “excellent.” Frequently discussed topics included meaning of result (99%), other risk factors (72%), and emotional impact of result (49%). Stigma and discrimination were rarely discussed, coming up in 12% and 3% of disclosure sessions, respectively. Challenges were infrequent (7%) and primarily included desire for additional information and challenges related to the participant's impairment. Clinicians provided the study team feedback about the disclosure process for 25% of disclosure visits. Comments included the desire for additional information or resources, positive feedback, and the importance of the study partner. Conclusions Clinicians disclosing amyloid PET results in ADNI‐4 report high confidence, adequate participant and study partner understanding, and few challenges. These data from clinicians, in combination with participant data, will inform future disclosure practices in both research and care.

Abstract Background The quantification of Neurofilament Light chain (NfL) in blood and cerebrospinal fluid (CSF) has proven valuable for diagnosing and prognosing various neurological disorders, including Alzheimer's disease, frontotemporal dementia, amyotrophic lateral sclerosis, parkinsonism, multiple sclerosis, and ischemic damage. However, there is considerable variability in clinical and laboratory practices between centers, primarily due to different contexts of use (COU), analytical methods, and the application of cutoffs or scales. Additionally, for the same biochemical profile, the interpretation and reporting of results may vary from one center to another, raising concerns about the commutability of the tests. To date, no consensus has been reached among laboratories to define the most appropriate use of cutoffs or conclusions/comments based on NfL profiles. Method This international project involves 38 laboratories across 18 countries, all specialized in the biochemical diagnosis of neurological disorders. Using a questionnaire, we obtained descriptions from each center regarding their COU, pre‐analytical and analytical protocols (including the biological fluid and methods used to quantify NfL). Through a consensus approach, we developed a harmonized strategy for the use and reporting of NfL results across different centres according to their respective COU. Results Among the centers, 63% quantified NfL in the CSF, 87% in blood and 53% in both fluids. COU were as follow: frontotemporal dementia (71%), Alzheimer disease (71%), multiple sclerosis (61%), amyotrophic lateral sclerosis (61%), psychiatric syndrome (45%), Creutzfeldt‐Jakob disease (32%), Parkinson disease (39%), peripheral neuropathy (29%), traumatic brain injury (21%), Huntington's disease (13%), amyloid transthyretin related (11%) and cardiac arrest (8%). Most of the centers define pathological cutoffs based on publications (50%) and take age into account for this purpose (42%). Reporting is mostly transmitted through numeric results (95%). Conclusion Harmonizing cutoffs, reporting, and interpretation across various clinical contexts will facilitate the incorporation of this biomarker into routine clinical practice.

Evidence-based practice is critical to providing high-quality hospice and palliative nursing care. Professional organizations, such as the Hospice and Palliative Nurses Association (HPNA), play a critical role in shaping the future of the hospice and palliative nursing field by identifying gaps in the science and fostering collaborative research efforts to inform evidence-based practices. One such driver is the tri-annual HPNA Research Agenda, which outlines key research priorities in hospice and palliative nursing, ultimately aiming to accelerate translation of research into practice and practice improvements. In this article, 6 emerging research scholars in the field and present and former co-chairs of the HPNA Emerging Research Scholar Special Interest Group reflect on the experiences that led them to pursue research careers in hospice and palliative nursing. Through a process of collective self-assessment, these scholars articulated their shared progress toward addressing the research priorities outlined in the 2023–2026 HPNA Research Agenda as a means of generating insights to direct future research efforts in the field.
