OBJECTIVES/OBJECTIVE:Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision-making process, we developed an evidence-based clinical practice guideline for the evaluation and management of peripheral nervous system manifestations in patients with Sjögren's disease. METHODS:A Topic Review Group (TRG), comprised of experts in rheumatology, neurology, and guideline methodology, developed Patient, Intervention, Comparison, and Outcome (PICO) questions and conducted a systematic review to identify current best evidence on management of PNS manifestations of Sjögren's disease. PubMed and Embase were searched for evidence published up to July 22, 2025. Literature screening, data extraction, and critical appraisal were performed in duplicate. Six case series, one retrospective cohort, and two prospective cohort studies lacking a comparison group met the inclusion criteria. RESULTS:We developed an aligned nomenclature of PNS terms that can be used across disciplines, 31 good practices for evaluation of suspected PNS manifestations, and 20 evidence-based treatment recommendations, the latter of which were rated as conditional or strong based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Due to the scarcity of high-level evidence, this guideline predominantly derives from expert opinion. CONCLUSION/CONCLUSIONS:This clinical practice guideline on PNS manifestations of Sjögren's disease provides clinicians a rigorous, evidence-based resource, developed through an expert consensus-based process, for the assessment, diagnosis, and treatment of peripheral neuropathy in Sjögren's patients. Recommendations were rated as strong when the benefits significantly outweighed potential harms, creating a scenario in which the majority of patients would prefer the advised action.

INTRODUCTION/BACKGROUND:Excessive salt intake is a major risk factor for cardiovascular disease (CVD) and premature mortality in China and globally. A recent cluster randomized controlled trial demonstrated the effectiveness of home cook interventions in reducing salt intake and blood pressure among participants from six provinces in China. Yet, it remains unclear whether expanding these interventions across China would be cost-effective. METHODS:The China CVD Prevention Model, a validated microsimulation model that captures the development and consequences of CVD among adults 35 years or older in China, was used to estimate lifetime averted CVD events and deaths, direct medical costs (2022 international dollar, Int$), quality-adjusted life years (QALYs) gained, and the incremental cost-effectiveness ratio (ICER) of home cook interventions versus the status quo. Costs and QALYs were discounted at 3%. RESULTS:Compared to the status quo, home cook interventions were projected to avert 1.97 million coronary heart disease (CHD) events, 3.69 million stroke events, 0.77 million deaths due to CHD, and 1.29 million deaths due to stroke in women. The interventions would also avert 1.62 million CHD events, 3.8 million stroke events, 0.6 million deaths due to CHD, and 1.15 million deaths due to stroke in men. The interventions resulted in an ICER of Int$3552/QALY in women and Int$5445/QALY in men and, thus, were cost-effective considering a willingness-to-pay threshold of Int$21,318 (one-time the gross domestic product per capita). CONCLUSIONS:Public health policymakers in China should consider widely adopting home cook interventions to better prevent CVD and reduce health care costs.

RECQL4 plays an important role in maintaining the integrity of the genome and regulating DNA replication. However, the role of RECQL4 in CNS tumors remains unknown. Sequencing data were reviewed and immunohistochemistry was performed on a variety of glial and nerve sheath tumors. Functional studies were performed in glioma (U251) and malignant peripheral nerve sheath tumors (MPNSTs) (NF90-8, ST88-14) cell lines following RECQL4 knockdown and treatment with ATR-inhibitors. Across 1580 CNS tumors, RECQL4 gene variants were identified in 71 cases (4.5%), with 21 (29.6%) of probable pathogenic significance. RECQL4 expression differed significantly across glioma subgroups (P = 0.012). Low-grade gliomas (diffuse: median H-score 57.5; circumscribed: median 130) showed lower expression than high-grade gliomas (median 145, P < 0.05). Neurofibromas displayed higher RECQL4 expression (median 160) compared with MPNSTs (median 97.5, P < 0.001). Among MPNSTs, NF1-associated cases (n = 24, median 95) expressed significantly less RECQL4 than sporadic cases (n = 8, median 162.5, P < 0.001). RECQL4 knockdown in glioma and MPNST cell lines resulted in increased apoptosis and susceptibility to ATR-inhibitors. Our findings show that RECQL4 expression has divergent patterns across tumor types and that targeting RECQL4 may dampen tumor survival and enhance susceptibility to ATR inhibitor therapy in CNS tumors.

BACKGROUND:Despite the goal of the 2018 revision to the heart allocation policy to reduce reliance on exception requests through improved granularity in status criteria, there has been a dramatic rise in exception requests. OBJECTIVES/OBJECTIVE:This study evaluated trends in exception use over the first 6 years of the updated policy, assessing associated clinical factors, temporal changes, and impact on waitlist outcomes. METHODS:This retrospective transplant registry analysis included all adult isolated heart transplant candidates from October 18, 2018, to September 30, 2024. Candidates were stratified by exception use, listing era, and region. Exception use was compared using Wilcoxon rank-sum and chi-squared tests, with multilevel logistic regression assessing independent associations. Trends over time and across UNOS (United Network for Organ Sharing) regions were evaluated, and a competing risks framework examined time to transplant and waitlist mortality. RESULTS:Among 26,330 candidates, 38.6% used exception requests, with a statistically significant increase over time, particularly in higher priority statuses. Exception use was more common among Black, non-Hispanic candidates, and candidates with blood type O, and less likely for patients with blood type A (P < 0.001). Additionally, pretransplant isolated durable left ventricular assist devices were less common in candidates who requested exceptions (19.0% vs 31.6%; P < 0.001). Overall, 39.9% of exception candidates were listed at status 1 or 2 compared to 29% of nonexception candidates, and 69.2% of exception candidates were removed from the waitlist at status 1 or 2 compared with 37% of nonexception candidates. CONCLUSIONS:The rising use of exceptions underscores ongoing limitations in allocation criteria, and disparities suggesting inequities in access to higher listing status. Policy refinements are needed to ensure a balance between medical urgency and equitable allocation.

BACKGROUND:Persistent chemotherapy-induced alopecia (pCIA) is a distressing side effect of antineoplastic agents, imposing significant psychological burdens on cancer survivors. Despite its impact, there are no standardized guidelines for diagnosis, prevention or management. OBJECTIVES/OBJECTIVE:To establish consensus-based definitions, diagnostic criteria, grading systems and management recommendations for pCIA. METHODS:A two-round Delphi method was conducted with 15 international experts in supportive oncodermatology and hair diseases from both Europe and the Americas. Statements were rated on a 5-point Likert scale, with a strong consensus defined as ≥75% agreement. Statements that did not achieve strong consensus in the first round were revised based on expert feedback and re-evaluated in a second-round survey. RESULTS:Strong consensus was reached on 47 statements (75.8%). pCIA was defined as non-scarring alopecia persisting beyond 6 months post-chemotherapy. Causes were attributed to the destruction of hair follicle stem cells, with taxanes, thiotepa and anthracyclines identified as key contributors. Consensus emphasized the importance of prevention of pCIA through scalp cooling devices, and the early intervention with topical or low-dose oral minoxidil was also recommended. Interestingly, the experts did not recommend the use of bicalutamide, oral finasteride and dutasteride (including in mesotherapy) for breast cancer patients with pCIA, citing potential safety concerns. CONCLUSIONS:This Delphi study established unified guidelines for pCIA, providing clinicians with a clear framework for diagnosis and treatment. Highlighting prevention through scalp cooling and timely interventions may improve outcomes for cancer survivors. Further research is necessary to assess new treatments and the long-term impact of chemotherapy on hair follicles.

BACKGROUND/UNASSIGNED:Movement of circulating lipids into tissues and arteries requires transfer across the endothelial cell (EC) barrier. This process allows the heart to obtain fatty acids, its chief source of energy, and apoB-containing lipoproteins to cross the arterial endothelial barrier, leading to cholesterol accumulation in the subendothelial space. Multiple studies have established elevated postprandial TRLs (triglyceride-rich lipoproteins) as an independent risk factor for cardiovascular disease. We explored how chylomicrons affect ECs and transfer their fatty acids across the EC barrier. METHODS/UNASSIGNED:C]oleate, we studied the uptake and release of this labeled by ECs. RESULTS/UNASSIGNED:]C labeled chylomicron triglycerides exited ECs primarily in phospholipids. EVs from chylomicron-treated versus untreated ECs were larger, more abundant, and contained specific microRNAs. Treatment of macrophages and naive ECs with media from chylomicron-treated ECs increased expression of inflammatory genes. CONCLUSIONS/UNASSIGNED:EC chylomicron metabolism produces EVs that increase macrophage inflammation and create LDs. Media containing these EVs also increases EC inflammation, illustrating an autocrine inflammatory process. Fatty acids within chylomicron triglycerides are converted to phospholipids within EVs. Thus, EC uptake of chylomicrons constitutes an important pathway for vascular inflammation and tissue lipid acquisition.

The rapid evolution of large-language models such as ChatGPT, Claude, and Gemini is reshaping the methodological landscape of obstetrics and gynecology (OBGYN) research. This narrative review provides a comprehensive account of generative AI capabilities, key use-cases, and recommended safeguards for investigators. First, generative AI expedites hypothesis generation, enabling researchers to interrogate vast corpora and surface plausible, overlooked questions. Second, it streamlines systematic reviews by composing optimized search strings, screening titles and abstracts, and identifying full-text discrepancies. Third, AI assistants can draft reproducible analytic code, perform preliminary descriptive or inferential analyses, and create publication-ready tables and figures. Fourth, the models support scholarly writing by suggesting journal-specific headings, refining prose, harmonizing references, and translating technical content for multidisciplinary audiences. Fifth, they augment peer-review and editorial workflows by delivering evidence-focused critiques. In educational settings, these models can create adaptive curricula and interactive simulations for trainees, fostering digital literacy and evidence-based practice early in professional development among clinicians. Integration into clinical decision-support pipelines is also foreseeable, warranting proactive governance. Notwithstanding these opportunities, responsible use demands vigilant oversight. Large-language models occasionally fabricate citations or misinterpret domain-specific data ("hallucinations"), potentially propagating misinformation. Outputs are highly prompt-dependent, creating a reliance on informed prompt engineering that may disadvantage less technical clinicians. Moreover, uploading protected health information or copyrighted text raises privacy, security, and intellectual-property concerns. We outline best-practice recommendations: maintain human verification of all AI-generated content; cross-validate references with primary databases; employ privacy-preserving, on-premises deployments for sensitive data; document prompts for reproducibility; and disclose AI involvement transparently. In summary, generative AI offers a powerful adjunct for OBGYN scientists by accelerating topic formulation, evidence synthesis, data analysis, manuscript preparation, and peer review. When coupled with rigorous oversight and ethical safeguards, these tools can enhance productivity without compromising scientific integrity. Future studies should quantify accuracy, bias, and downstream patient impact.

BACKGROUND:There are risks associated with excessive intravenous fluid (IVF) administration in critically ill children. Previous efforts have described opportunities to reduce positive cumulative fluid balance (CFB) in this population but have not been widely implemented. In the wake of Hurricane Helene, a national IVF shortage led to the implementation of IVF conservation guidelines. We sought to determine if this was associated with a reduction in IVF use and CFB. METHODS:The present study is a four-site cohort study of critically ill children utilizing a federated data collection framework to extract patient age, sex, weight, and daily fluid intake/output for days 1-4 of all admissions 28 days prior to and 28 days after the implementation of IVF conservation guidelines. Guidelines were individualized per institution. Total fluid intake, total IVF intake, % intake from IVF, and % CFB were compared between pre- and post-IVF conservation groups. RESULTS:All sites had similar conservation recommendations. There were 633 patients admitted pre- and 619 patients admitted post-IVF conservation guideline implementation, with similar age and weight distributions. There was no significant difference in IVF use pre- and post-IVF conservation; 29-35% of patients had > 5% CFB on day 1 pre-IVF conservation while 27-39% did post-conservation, with increasing numbers on day 2. CONCLUSIONS:Even in the setting of a national IVF shortage, simple recommendations without structured change were insufficient to change IVF administration practices. This indicates additional practices will be needed to reduce IVF intake and % CFB in this vulnerable population.

INTRODUCTION/BACKGROUND:Neurologic complications, including seizures, are common in pediatric patients undergoing heart surgery, especially those requiring postoperative extracorporeal membrane oxygenation (ECMO), requiring prompt, vigilant postoperative monitoring. Prolonged EEG monitoring in critically ill children presents a risk of scalp/pressure injuries. The skin's sensitivity to microcirculatory changes can also provide valuable insights into the patient's overall tissue perfusion, making it a critical component in the management of these vulnerable patients. METHODS:We initiated a quality improvement (QI) project to assess and reduce scalp injuries related to prolonged EEG monitoring in critically ill neonates and infants. The project involved reviewing baseline data, which included 2336 inpatient video EEGs performed from January 2022 to December 2024, and implementing interventions to improve skin safety during electrode placement, while incorporating best practices from ACNS and ASET guidelines. RESULTS:Five critically ill infants developed deep tissue injuries (DTIs) related to EEG electrodes, with most injuries occurring over the occipital region. The frequency of scalp injuries decreased from 0.30% in 2022 to 0% in 2024 after implementing the QI protocol, and was observed in conditions with known hypoperfusion. DISCUSSION/CONCLUSIONS:Electrode-related skin injuries are a common complication of prolonged EEG monitoring, particularly in critically ill pediatric patients. Our findings suggest that adherence to expert guidelines and tailored skin care protocols focused on skin preparation, electrode application, and monitoring parameters can reduce the risk of electrode-related skin injuries. Further research is needed to refine safety protocols and address the unique skin care challenges faced by this high-risk population.

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.
