A cluster of Aspergillus fumigatus donor-derived infections (DDI) was rapidly diagnosed using plasma metagenomic next-generation sequencing (mNGS) among solid organ transplant recipients. The heart recipient, experiencing marginal hemodynamics, underwent an endomyocardial biopsy, which was concerning for a fungal infection on histopathology. Plasma mNGS was performed, identifying A. fumigatus two days prior to conventional diagnostics. This timely diagnosis enabled prompt nephrectomies in the kidney recipients, who survived. This report represents the first published use of mNGS in the diagnosis of Aspergillus fumigatus DDI, highlighting the utility of this novel, underutilized assay for early diagnosis of donor-derived infections.

OBJECTIVES/UNASSIGNED:This study evaluates and enhances language access services for Limited English Proficiency (LEP) patients in a large urban health system by integrating interpreter services into the Electronic Health Record (EHR), aiming to reduce care disparities and improve the digital experience for both patients and clinicians. MATERIALS AND METHODS/UNASSIGNED:Using a descriptive evaluation approach, the project assessed barriers to interpreter service usage and developed solutions informed by stakeholder engagement. Emphasis was placed on interfacing the EHR with the vendor platform, using existing devices, tracking utilization, ensuring cost-effectiveness, and implementing the solution across multiple hospitals and outpatient settings. RESULTS DISCUSSION AND CONCLUSION/UNASSIGNED:After implementation, audio and video interpreter service use rose significantly, with calls increasing from an average of 9700 calls per month in 2022 to over 68 176 calls per month by the end of 2024. Over 14 000 clinicians used the service for more than 121 077 unique patients. Average waiting times for the top ten languages fell below 30 seconds, and user satisfaction was high, with an average interpreter rating of 4.9. Conclusion: The EHR-integrated interpreter service has improved language service access, reduced waiting times and enhanced user satisfaction, marking noteworthy progress in overcoming language barriers and potentially decreasing healthcare disparities for LEP populations. We plan to assess the impact on patient outcomes.

BACKGROUND & AIM/UNASSIGNED:Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing health issue. Identifying factors that prevent hepatic lipid accumulation could inform new MASLD prevention or treatment strategies. We previously demonstrated that adipocyte microsomal triglyceride transfer protein (MTP) regulates intracellular lipolysis by inhibiting adipose triglyceride lipase activity. The aim of this study was to investigate the impact of adipose MTP deficiency on MASLD. METHODS/UNASSIGNED: RESULTS/UNASSIGNED: CONCLUSION/UNASSIGNED:These findings highlight the importance of regulated FA flux from adipose tissue to the liver and the liver's adaptive capacity to utilize adipose-derived FAs in maintaining hepatic health. Modulation of adipocyte FA release may represent a therapeutic strategy to reduce hepatic steatosis. IMPACT AND IMPLICATIONS/UNASSIGNED:This study provides significant insights into the role of adipose-specific microsomal triglyceride transfer protein in regulating hepatic lipid metabolism and its potential implications for treating metabolic dysfunction-associated steatotic liver disease. By demonstrating that microsomal triglyceride transfer protein deficiency in adipose tissue leads to increased fatty acid oxidation and reduced hepatic steatosis through enhanced PPARα activation, the research underscores the importance of adipose-liver crosstalk in maintaining liver health. These findings suggest that targeting adipocyte fatty acid release could be a promising therapeutic strategy to mitigate hepatic lipid accumulation and combat metabolic dysfunction-associated steatotic liver disease, offering a novel approach to addressing this growing health issue.

Advocacy has long been at the core of the infectious diseases (ID) field, with clinicians and researchers advocating to ensure patients can access the care they need on an individual and global scale. The Infectious Diseases Society of America Training Program Directors' (PD) Committee met in 2024 and discussed ways that advocacy is and should be incorporated into fellowship training, as well as highlighted the role PDs play in advocating for their trainees. Policies with a negative impact on ID clinical care, public health, and research underscore the importance of mobilizing the field of ID to advocate for the patients and communities we serve, as well as for ourselves. This paper presents ideas generated at this meeting and is meant to serve as a reference for ID PDs, as well as the wider ID community, as a call to action for teaching and participating in advocacy work.

BACKGROUND/UNASSIGNED:Stenting of bifurcation and non-aorto-ostial coronary lesions presents significant challenges due to geographic miss and restenosis. Drug-coated balloons (DCBs) offer an attractive alternative to drug-eluting stents in the treatment of these lesions. METHODS/UNASSIGNED:We conducted a systematic review of studies published from 2001 to 2024 comparing DCBs with plain old balloon angioplasty and/or drug-eluting stents (DES) in de novo coronary bifurcation lesions and non-aorto-ostial (NAO) lesions. A meta-analysis was performed with target lesion failure (TLF) as the selected outcome, defined as a composite of target lesion revascularization, target vessel myocardial infarction, or cardiovascular death. RESULTS/UNASSIGNED:= .0015), respectively. CONCLUSIONS/UNASSIGNED:In our meta-analysis, DCBs were associated with a lower rate of TLF compared with plain old balloon angioplasty and DES. These findings suggest that DCBs could be preferred for the treatment of bifurcation and NAO lesions.

INTRODUCTION/BACKGROUND:Process evaluation provides insight into how interventions are delivered across varying contexts and why interventions work in some contexts and not in others. This manuscript outlines the protocol for a process evaluation embedded in a hybrid type 1 effectiveness-implementation randomised clinical trial of incremental-start haemodialysis (HD) versus conventional HD delivered to patients starting chronic dialysis (the TwoPlus Study). The trial will simultaneously assess the effectiveness of incremental-start HD in real-world settings and the implementation strategies needed to successfully integrate this intervention into routine practice. This manuscript describes the rationale and methods used to capture how incremental-start HD is implemented across settings and the factors influencing its implementation success or failure within this trial. METHODS AND ANALYSIS/METHODS:We will use the Consolidated Framework for Implementation Research (CFIR) and the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) frameworks to inform process evaluation. Mixed methods include surveys conducted with treating providers (physicians) and dialysis personnel (nurses and dialysis administrators); semi-structured interviews with patient participants, caregivers of patient participants, treating providers (physicians and advanced practice practitioners), dialysis personnel (nurses, dieticians and social workers); and focus group meetings with study investigators and stakeholder partners. Data will be collected on the following implementation determinants: (a) organisational readiness to change, intervention acceptability and appropriateness; (b) inner setting characteristics underlying barriers and facilitators to the adoption of HD intervention at the enrollment centres; (c) external factors that mediate implementation; (d) adoption; (e) reach; (f) fidelity, to assess adherence to serial timed urine collection and HD treatment schedule; and (g) sustainability, to assess barriers and facilitators to maintaining intervention. Qualitative and quantitative data will be analysed iteratively and triangulated following a convergent parallel and pragmatic approach. Mixed methods analysis will use qualitative data to lend insight to quantitative findings. Process evaluation is important to understand factors influencing trial outcomes and identify potential contextual barriers and facilitators for the potential implementation of incremental-start HD into usual workflows in varied outpatient dialysis clinics and clinical practices. The process evaluation will help interpret and contextualise the trial clinical outcomes' findings. ETHICS AND DISSEMINATION/BACKGROUND:The study protocol was approved by the Wake Forest University School of Medicine Institutional Review Board (IRB). Findings from this study will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER/BACKGROUND:NCT05828823.

Families of infants hospitalized in the neonatal intensive care unit (NICU) are at an increased risk for depression, anxiety, and trauma symptoms that often persist well beyond transition from the NICU. While NICU professionals provide vital medical care for high-risk infants, they also offer interdisciplinary support for families, including collaboration with psychosocial and psychiatric services in select settings. Despite psychosocial support systems often being present during NICU hospitalization, significant gaps remain in post-NICU mental health support for parents. Comprehensive discharge preparation and outpatient follow-up planning for infants, as well as their families, are essential to optimize both long-term outcomes and the well-being of the entire family unit. In this paper, we review current evidence regarding mental health risks for families during transitions of care and highlight practice recommendations and advocacy opportunities for enhanced family-centered, interdisciplinary follow-up care after transition from the NICU.
