Background/Purpose APS ACTION Registry was created to study the natural course of antiphospholipid syndrome (APS) over 10 years in persistently antiphospholipid antibody (aPL) positive patients with or without systemic autoimmune rheumatic diseases (SARDs). Our primary objective was to compare the characteristics of aPL-positive patients with or without thrombocytopenia (TP) and/or autoimmune hemolytic anemia (AIHA). Methods The registry inclusion criteria are positive aPL based on the Revised Sapporo APS Classification Criteria, tested at least twice within 1 year prior to enrollment. For the primary comparison of demographic, clinical, and serologic characteristics in this retrospective study, we divided patients into two groups: TP/AIHA ever and never. Thrombocytopenia was defined as a platelet count of <100,000 x 10 9 /L tested twice at least 12 weeks apart, and AIHA was defined as anemia with hemolysis and a positive direct antiglobulin test (DAT). For the secondary analysis, we compared patients with TP versus AIHA, and the immunosuppressive use stratified by systemic lupus erythematosus (SLE) classification. Results As of April 2022, of 1,039 patients (primary aPL/APS: 618 [59%]; SLE classification: 334 [31%]) included in the registry, 228 (22%) had baseline (historical or current) TP and/or AIHA (TP only: 176 [17%]; AIHA only: 35 [3%], and both: 17 [2%]). Thrombocytopenia and/or AIHA was significantly associated with Asian race, SLE classification, cardiac valve disease, catastrophic/microvascular APS, triple aPL (lupus anticoagulant, anticardiolipin antibody, and anti-β 2 -glycoprotein-I antibody) positivity, and SLE-related serologic and inflammatory markers. When 101/618 (16%) primary aPL/APS patients and 101/334 (34%) SLE patients with TP and/or AIHA were compared, azathioprine and mycophenolate mofetil were more commonly reported in lupus patients, however corticosteroid, intravenous immunoglobulin, and rituximab use were similar between groups. Conclusion In our large multi-center international cohort of persistently aPL-positive patients, approximately one-fifth had active or historical TP and/or AIHA at registry entry; half of these patients had additional SLE. Cardiac valve disease, catastrophic/microvascular APS, and triple aPL-positivity were aPL-related clinical and laboratory manifestations associated with TP and/or AIHA, suggesting a more severe APS clinical phenotype in aPL-patients with TP and/or AIHA.

Abstract Background Adults with congenital heart disease (ACHD) frequently experience gaps in lifelong ACHD specialty care, leading to preventable complications, hospitalizations, and premature mortality. However, effective, scalable, accessible, and sustainable strategies to reduce these gaps are lacking. Digital health offers potential solutions but requires a rigorous scientific approach in its design to address the needs of the target population. Objective To describe the development of a theory-based, community co-designed digital health intervention to improve lifelong ACHD care. Methods We integrated theory-based behavioral frameworks, semi-structured qualitative interviews with patients and clinicians, and a community-engaged approach to develop a digital health intervention for ACHD. The primary behavioral target was completing an ACHD specialist appointment. We conducted Capability, Opportunity, Motivation, and Behavior (COM-B)-guided semi-structured interviews with ACHD patients and clinicians to identify barriers to specialized care amenable to a digital intervention and patient-centered goals for the digital tool. The community partners helped develop key intervention objectives, create a theory-driven framework, and specify how each intervention component targets specific COM-B barriers. Results We interviewed 54 participants (37 ACHD patients and 17 clinicians) and engaged 21 community partners representing 4 advocacy organizations. Design objectives emphasized addressing patient loneliness, ensuring accessibility and credibility, and enabling scalability while centering patient perspectives. Participants identified four priorities: providing credible resources, uplifting patient voices, customizing to patient needs, and centering positivity and joy. The digital tool, named by community partners as Empower My Congenital Heart (EMCH), was designed within the web- and mobile-based, Apple- and Android-compatible, Eureka Digital Research platform (University of California, San Francisco). Key intervention components included educational modules, peer support, appointment planning nudges, and a digital medical passport. The EMCH’s theory-driven framework specifies how each intervention component targets specific COM-B barriers to specialized ACHD care. Conclusions The theory-driven, community co-designed EMCH digital tool is a rapidly scalable approach to improve guideline-recommended specialized ACHD care. Future studies will evaluate the acceptability, feasibility, effectiveness, and implementation outcomes to provide insight into a novel tool to reduce preventable morbidity and mortality in ACHD. Trial Registration The National Clinical Trial number for this study is NCT06581484 .

Chronic pain is common with aging. Yet, little is known about the attitudes, beliefs, and experiences of older adults with chronic pain regarding opioids, particularly in regard to effects on daily functioning and cognition. This qualitative analysis employed semi-structured interviews in 25 community-dwelling older adults with chronic pain and current or recent prescription opioid use. Interviews focused on perceptions, beliefs, and experiences of living with chronic pain, use of prescription opioids, and the impact of opioids on pain control, cognition, and daily function. Older adults display adaptability and acceptance in living with chronic pain, desire person-centered pain care, approach the risks-benefits of opioids with regards to cognition differently, and perceive stigma as a barrier to effective partnership with clinicians.

Objectives/Goals: Aspiration causes or aggravates lung diseases. While bedside swallow evaluations are not sensitive/specific, gold standard tests for aspiration are invasive, uncomfortable, expose patients to radiation, and are resource intensive. We propose the development and validation of an AI model that analyzes voice to noninvasively predict aspiration. Methods/Study Population: Retrospectively recorded [i] phonations from 163 unique ENT patients were analyzed for acoustic features including jitter, shimmer, harmonic to noise ratio (HNR), etc. Patients were classified into three groups: aspirators (Penetration-Aspiration Scale, PAS 6–8), probable (PAS 3–5), and non-aspirators (PAS 1–2) based on video fluoroscopic swallow (VFSS) findings. Multivariate analysis evaluated patient demographics, history of head and neck surgery, radiation, neurological illness, obstructive sleep apnea, esophageal disease, body mass index, and vocal cord dysfunction. Supervised machine learning using five folds cross-validated neural additive network modelling (NAM) was performed on the phonations of aspirator versus non-aspirators. The model was then validated using an independent, external database. Results/Anticipated Results: Aspirators were found to have quantifiably worse quality of sound with higher jitter and shimmer but lower harmonics noise ratio. NAM modeling classified aspirators and non-aspirators as distinct groups (aspirator NAM risk score 0.528+0.2478 (mean + std) vs. non-aspirator (control) risk score of 0.252+0.241 (mean + std); p Discussion/Significance of Impact: We report the use of voice as a novel, noninvasive biomarker to detect aspiration risk using machine learning techniques. This tool has the potential to be used for the safe and early detection of aspiration in a variety of clinical settings including intensive care units, wards, outpatient clinics, and remote monitoring.

BACKGROUND Malignant peripheral nerve sheath tumors (MPNSTs) are rare and highly malignant tumors of neural crest origin. No matter their anatomical location, they are difficult to treat and carry a poor prognosis. OBSERVATIONS This report highlights the complexities of the diagnosis and management of a patient with MPNST of the cauda equina. The tumor retained the expression of H3K27me3, which is expected in spinal MPNSTs but uncommon in most sporadic and neurofibromatosis type 1–driven MPNSTs. LESSONS The described diagnostic nuance should be taken into consideration in patients with suspected MPNST of the cauda equina, as these tumors require swift neurosurgical intervention in order to maintain neurological function. Additional treatment modalities include neoadjuvant and adjuvant chemotherapy and radiotherapy. Although improvements in local control and progression-free survival have been reported, the role of radiation therapy and chemotherapy has been underinvestigated due to the rarity of MPNSTs presenting in this region. https://thejns.org/doi/10.3171/CASE24723

Background Over half of ICU survivors experience post intensive care syndrome (PICS). Few PICS clinics were operational in the United States at the onset of the COVID-19 pandemic. Here we describe early experience of such a clinic at a large academic medical center. Our objective was to describe the (a) model of care (b) clinic interventions (c) short-term cognitive, psychiatric, and functional outcomes (d) one-year outcomes of COVID-19 ICU survivors at the Cleveland Clinic post-ICU recovery clinic (PIRC). Methods We conducted a retrospective cohort study through a chart review of all patients seen in PIRC from April 2020 – December 2020. A total of 59 patients completed the visit with 49% being virtual, and 51% being in-person. The cohort was predominantly white (50.8%), and male (57.6%) with a median age of 58.2 years. We screened for cognitive and psychiatric impairments using several different validated questionnaires. Functional impairments were self-reported and detected after assessment by a physical therapist. Quantifiable clinic interventions were referrals, pharmacy medication reconciliation, and vaccine administration. One-year outcomes were health care utilization, and death. Results In our cohort, 36%, 39.6%, and 17% of patients screened positive for cognitive impairment, anxiety and/or depression, and PTSD respectively. 42.3% of patients had lower extremity mobility impairment. 57.6% of patients required at least one referral after clinic. Of the 67.9% of patients who were working and 93.9% driving prior to hospitalization, only 24.6% and 73.2% had returned to those activities, respectively. The most common pharmacy intervention was discontinuation of a medication no longer in use. By one year, 34% of patients had hospital re-admissions with 5% requiring the ICU. There were no deaths. Conclusions Adult survivors of COVID-19 critical illness have impairments in all PICS domains as well as high health care utilization in the first year after hospital discharge. MeSH Terms Post intensive care syndrome, COVID-19 Key Points/Summary Adult survivors of COVID-19 critical illness have impairments in all PICS domains as well as high health care utilization in the first year after hospital discharge. Post-ICU recovery clinics can help survivors with recovery.

Background: Preventing infections associated with cardiac implantable electronic devices (CIED) and neurostimulators is essential to optimizing patient outcomes. This study aimed to evaluate the antimicrobial performance of a biologic CIED envelope incorporating a bioabsorbable disc infused with rifampin and minocycline. Methods: The antimicrobial activity was evaluated in a rabbit model and in vitro elution tests. Based on in vivo–in vitro correlation studies, a modified AATCC-100 method was used to quantitatively assess antibacterial activity across seven bacterial strains relevant to CIED infections. Results: Pharmacokinetic analysis showed a biphasic elution profile, with rapid initial release followed by more gradual elution over 14 days. The AATCC results showed no bacterial recovery for any tested species, with complete eradication in all replicates. Conclusions: These results support the use of antibiotic-eluting bioenvelopes as an effective strategy for preventing bacterial infections associated with CIED. The modified AATCC-100 test and in vivo–in vitro correlation studies provide new tools for the evaluation of the antibiotic activity of implantable biomaterials.

Abstract “Nonclassical” myeloproliferative neoplasms (MPNs) and myelodysplastic/myeloproliferative neoplasms (MDS/MPNs) represent a heterogeneous group of malignancies characterized by a wide range of clinical manifestations. Unlike classical MPNs, there is no standardized management approach for these conditions, particularly concerning the indications for and management of allogeneic hematopoietic cell transplantation. To address this gap, the European Society for Blood and Marrow Transplantation (EBMT) Practice Harmonization and Guidelines (PH&G) Committee and the Chronic Malignancies Working Party (CMWP) have collaborated to develop shared guidelines aimed at optimizing the selection and management of patients with these rare forms of neoplasms. A comprehensive review of the literature from the publication of the revised fourth edition of the (2016) World Health Organization classification onward was conducted. A multidisciplinary group of experts in the field convened to produce this document, which was developed through multiple rounds of draft circulation. Key recommendations include the early identification of potential transplant candidates, particularly in cases of chronic neutrophilic leukemia, chronic eosinophilic leukemia (CEL)/CEL, not otherwise specified (CEL-NOS), myeloid/lymphoid neoplasm with eosinophilia and tyrosine kinase gene fusions with FGFR1, JAK2, ABL1, and FLT3 rearrangements, MDS/MPN with neutrophilia/atypical chronic myeloid leukemia, and MDS/MPN, NOS. For patients with MPN, NOS/MPN unclassifiable, standard recommendations for myelofibrosis should be applied. Similarly, in MDS/MPN with thrombocytosis, transplantation is recommended on the basis of established MDS guidelines. Given the current lack of robust evidence, this document will serve as a valuable resource to guide future research activities, providing a framework for addressing critical unanswered questions and advancing the field.
