Sex and gender influence disease mechanisms and outcomes, yet their integration into medical curricula remains limited. Faculty knowledge and confidence are essential for effective incorporation. This study assessed baseline sex- and gender-specific health (SGSH) knowledge, attitudes, and comfort among medical school educators and delivered a multi-format faculty development intervention. A survey adapted from prior SGSH assessments was distributed to medical school block leaders before the intervention, measuring SGSH knowledge, comfort differentiating sex and gender, awareness of SGSH resources, and readiness to integrate SGSH content. The intervention included virtual and in-person grand rounds, distribution of How Sex and Gender Impact Clinical Practice , and a screening of Ms. Diagnosed . Of the 103 invited to participate, 68 educators (66% response rate) completed the baseline survey. Forty percent reported no prior SGSH training, and only 13.2% felt very comfortable with SGSH concepts. Although 94.1% correctly identified gender as a social construct and sex assignment at birth, 22% remained uncomfortable distinguishing the two. More than 80% were neutral or uncomfortable identifying SGSH resources. Comfort with curriculum integration varied: 45.6% felt comfortable, 32.4% neutral, and 22.1% uncomfortable, with differences observed across specialties. These findings reveal significant gaps in medical educators’ SGSH knowledge and comfort regardless of experience, with SGSH content narrowly confined to reproductive health topics. Simply providing resources is insufficient; educators need structured guidance on integration. By outlining baseline gaps and an intervention model, this study offers a framework for institutions seeking to enhance SGSH integration through interactive, longitudinal, multi-format faculty development approaches.

Abstract Background Strongyloides stercoralis is an intestinal parasitic nematode with a 2% - 7% prevalence in the United States. Immunosuppression can predispose to disseminated infection, concurrent bacterial sepsis and significant morbidity and mortality. We sought to review positive Strongyloides serology (PSS) results across 3 academic medical centers. Methods Electronic medical records of patients with PSS were reviewed between 2012 and 2023. Extracted data included demographics, country of origin, travel history, testing indication, clinical presentation, treatment regimen and duration. Patients were classified into chronic infection (PSS without additional clinical manifestations), hyper infection syndrome (cutaneous, gastrointestinal tract, or lung involvement), and disseminated infection (evidence of involvement of distant sites beyond hyper infection such as the brain, liver, kidneys, or bloodstream). Results Overall PSS rate across the 3 sites was 5.5%. A total of 412 patients with PSS were identified with a mean age of 56.7 years (SD ±14.2); 272 (66%) were male. The primary indication for testing was transplant evaluation in 230 (56%), eosinophilia workup in 84 (20%), suspicion of active infection in 74 (18%), travel history in 27 (7%), and pre-immunosuppression screening in 27 (7%). 401 (97.3%) were categorized as chronic infection,10 (2%) as hyper infection, and one patient (0.2%) as disseminated infection. Treatment was administered to 366 (89.3%) patients: 226 (61.7%) received 2 doses of Ivermectin on consecutive days, 94 (25.7%) received a single dose, 26 (7.1%) received 2 doses repeated 2 weeks later, and 20 (5.5%) received alternative regimens. The patient with disseminated infection received 2 weeks of Ivermectin followed by monthly dosing. Conclusion Majority of the patients with PSS were asymptomatic, and treatment regimens were not uniform. Screening should be considered for patients currently receiving or initiating long-term immunosuppression that can potentiate Strongyloides dissemination. Developing a targeted testing algorithm based on epidemiologic factors, clinical suspicion, laboratory parameters and nature of immunosuppression can help identify at-risk patients who can receive pre-emptive therapy if infected.

Introduction: Cardiac involvement in patients with systemic sclerosis (SSc) can present variably from being asymptomatic to manifesting with heart failure, conduction abnormalities, pulmonary hypertension, and pericardial effusion. Symptomatic cardiac involvement portends a poor prognosis and worse overall survival. Sacubitril/valsartan (SV), an angiotensin receptor neprilysin inhibitor, has been shown to significantly reduce hospitalization rates and morbidity in patients with heart failure with reduced ejection fraction (HFrEF). This study aimed to investigate the effects of SV treatment in patients with SSc and heart failure. Methods: A retrospective analysis of patients with SSc was conducted using an electronic data capture tool. Patients with SSc treated with SV between January 2015 and August 2023 were identified. Comprehensive clinical phenotyping and longitudinal data analysis were performed to characterize the sub-type of patients and evaluate clinical outcomes, including hospitalizations and mortality, laboratory markers, and echocardiographic findings. Results: Twenty-four patients with SSc were treated with SV for a mean duration of 20.6 months. HFrEF was the primary indication for SV use in 91% of patients, primarily due to non-ischemic cardiomyopathy (87.5%). There was a significant reduction in systolic blood pressure from 128 mmHg to 114 mmHg (p < 0.001) and NT-proBNP levels from 15,130 pg/mL to 5082 pg/mL (p = 0.046). In the 19 patients with baseline and follow-up echocardiograms, there was a significant improvement in LVEF from 40.3% to 47.7% (p = 0.014). Hypotension was a common side effect leading to discontinuation of SV (n = 4, 16.7%). Serum creatinine had trends of improvement (1.9 mg/dL to 1.3 mg/d), though it did not reach statistical significance (p = 0.057). Conclusions: This study showed that SV effectively improved cardiac symptoms and function in patients with SSc presenting with HFrEF. Further prospective studies are needed to confirm these findings and explore the role of SV in the treatment of other manifestations of SSc.

Abstract Introduction: Multiple myeloma (MM) is a B-cell-derived malignancy associated with immune dysregulation. Anti-CD38 monoclonal antibodies (mAbs) therapies have shown improved outcomes in patients with MM. Silbermann et al. showed that anti-CD38 mAb-containing therapies lead to profound hypogammaglobulinemia and reduction in Ig gene repertoire. The effect of modern therapies such as CAR-T and bispecific antibodies (BsAbs) on B-cell repertoire has not been well described. In this study, we sought to investigate the effect of these therapies on B-cell repertoire in patients with MM. Methods: This is a single-institution retrospective observational study evaluating MM patients treated with anti-BCMA CAR-T and BsAbs. Baseline characteristics, laboratory data, treatment history, were extracted from medical records. Total unique sequences (TUS) and total sequences of IgH, IgK, and IgL were identified and quantified using clonoSEQ. Patients were classified in two groups: CAR-T and BsAbs. The primary objectives were (1) characterize changes in TUS and total sequences within IgH, IgK, and IgL before and after treatment, and (2) examine how the sequences evolve over time following CAR-T. Results: 76 MM patients received CAR-T or BsAbs. Among those, 22 CAR-T and 5 BsAbs patients had pre- and post-treatment sequences available. Median age at initiation of treatment was 66 years in the CAR-T group (42-81 y) and 65 years in the BsAbs group (48-71 y). Based on mSMART v3 criteria, 72% of CAR-T and 60% of BsAbs recipients were classified as high-risk. Median number of prior lines of therapy was 5 (2-8) in the CAR-T group and 6 (5-13) in the BsAbs group.CAR-T recipients were classified into early (&lt;40 days) and late (&gt;40 days), based on when the post-CAR-T treatment clonoSEQ assay was performed. Changes in TUS and total sequences of IgH, IgK, and IgL were calculated, and the averages were assessed independently. The mean early and late change in total unique IgH sequences were (-75, 586 and 131, 038, p=0.052), unique IgK (-57, 797 and 52, 586, p=0.020), and unique IgL (-22, 354 and 25, 056, p=0.011). A subgroup of 8 patients with sequential MRD reports post-CAR-T therapy were identified, six patients showed improvement in B-cell sequence dynamics and two patients showed a decrease over time. For patients who received BsAbs, results indicated a similar pattern, with an early decrease in B-cell repertoires, characterized by reductions in sequence diversity and quantity. Conclusions: Our analysis of B-cell repertoires following CAR-T revealed changes before and after treatment. Patients receiving CAR-T therapy showed a decline in the number of TUS and total sequences of IgH, IgK, and IgL, likely due to the lymphodepletion regimen, followed by a gradual restoration reflecting immune recovery. Longer follow-up and a larger cohort will be necessary to assess the implications of these B-cell repertoire changes on patient outcomes.

Abstract Introduction: Pragmatic trials aim to speed translation to practice by integrating study procedures in routine care settings. This study evaluated implementation outcomes related to clinician and patient recruitment and participation in a trial of community paramedicine (CP) and presents successes and challenges of maintaining pragmatic study features. Methods: Adults in the pre-hospital setting, emergency department (ED), or hospital being considered for referral to the ED/hospital or continued hospitalization for intermediate-level care were randomized 1:1 to CP care or usual care. Referral and enrollment data were tracked administratively, and patient characteristics were abstracted from the electronic health record (EHR). Enrolled patients completed baseline surveys, and a subset of intervention patients were interviewed. All CPs and a sample of clinicians and administrators were invited to complete a survey and interview. Results: Between January 2022 and February 2023, 240 enrolled patients (42% rural) completed surveys, and 22 completed an interview; 63 staff completed surveys and 20 completed an interview. Ninety-three clinicians in 27 departments made at least one referral. Factors related to referrals included program awareness and understanding the CP practice scope. Most patients were enrolled in the hospital, but characteristics were similar to the primary care population and included older and medically complex patients. Challenges to achieving representativeness included limited EHR infrastructure, constraints related to patient consenting, and clinician concerns about patient randomization disrupting preferred care. Conclusion: Future pragmatic trials in busy clinical settings may benefit from regulatory policies and EHR capabilities that allow for real-world study conduct and representative participation.

INTRODUCTION: We examined autoimmunity markers (AIM) and autonomic dysfunction in patients with chronic neurogastroenterological symptoms and their relationship to joint hypermobility/hypermobility spectrum disorder (JH/HSD). METHODS: AIM positivity was defined as a diagnosis of known autoimmune/autoinflammatory disorder with at least 1 positive seromarker of autoimmunity or at least 2 positive seromarkers by themselves. Three cohorts were studied: (i) retrospective (n = 300), (ii) prospective validation cohort (n = 133), and (iii) treatment cohort (n = 40), administered open-label intravenous immunoglobulin (IVIG). RESULTS: AIM positivity was found in 40% and 29% of the retrospective and prospective cohorts, the majority of whom (71% and 69%, respectively) had autoinflammatory disorder. Significantly more patients with AIM had elevations of C-reactive protein (31% vs 15%, P < 0.001) along with an increased proportion of cardiovascular autonomic dysfunction (48% vs 29%; P < 0.001), small fiber neuropathy (20% vs 9%; P = 0.002), and HLADQ8 positivity (24% vs 13%, P = 0.01). Patients with JH/HSD were more likely to have AIM (43% vs 15%, P = 0.001) along with more severe autonomic and gastrointestinal (GI) symptom scores. IVIG treatment was associated with robust improvement in pain, GI, and autonomic symptoms, but adverse events were experienced by 62% of patients. DISCUSSION: Autoimmune markers and autonomic dysfunction are common in patients with unexplained GI symptoms, especially in those with JH/HSD. Many patients seem to respond to IVIG treatment, but this needs to be confirmed by controlled trials. These results highlight the need for vigilance for autoimmune and autonomic factors and JH/HSD in patients with neurogastroenterological disorders. Clinicaltrials.gov, NCT04859829.

Abstract Background Chronic migraine exerts substantial negative impacts on daily functioning. Efforts to manage impaired functioning may result in medication overuse, which contributes to the worsening profile and chronification of migraine. The Migraine Functional Impact Questionnaire (MFIQ) is a recently developed measure assessing the impact of migraine on physical, social, and emotional function. Objective The objective of this analysis was to assess changes in MFIQ scores following initiation or modification of migraine preventive medication and determine if changes in function are associated with changes in other aspects of migraine burden, such as headache frequency, headache intensity, and symptoms of anxiety and depression. Methods This is a secondary analysis of data from the Medication Overuse Treatment Strategy (MOTS) trial, a prospective pragmatic clinical trial that investigated two treatment strategies for those with chronic migraine and medication overuse. Data from both treatment arms were pooled and analyzed using a pre–post design. Prior to and 12 weeks following initiation or modification of migraine preventive medication, participants completed a series of questionnaires that captured migraine characteristics, medication use, migraine‐related physical impairment (MFIQ), anxiety (Generalized Anxiety Disorder‐7), and depression (Patient Health Questionnaire 9 [PHQ‐9]) symptoms. Changes from baseline in all measures were assessed using the paired t ‐test. Relationships between changes in MFIQ scores and other measures were assessed using linear regression. Multivariable modeling was performed to determine which additional variables contributed to the change in MFIQ beyond that already explained by an individual variable. Model terms were selected by using elastic net regularization. Only those participants who completed the baseline and 12‐week MFIQ were included in this analysis. Results Of the 537 patients, 88.2% were female, and the average age was 45 years (standard deviation 13). The mean frequency of days with moderate‐to‐severe headache improved 39.2% from 13.5 per 30 days at baseline to 8.1 per 30 days at week 12. The mean MFIQ Usual Activities Global score improved by 15.0 points (on a 100‐point scale). All five domains (Usual Activities Global, Usual Activities, Social Function, Emotional Function, Physical Function) of the MFIQ improved by a mean of at least 13.0 points. Changes in PHQ‐9 score, followed by changes in headache frequency, had the strongest associations with change in all domains of the MFIQ. Conclusions The negative impact of chronic migraine with medication overuse on physical, social, and emotional functioning substantially lessened following initiation or modification of migraine preventive medication. Improved functioning, as measured by the MFIQ, was most strongly associated with reductions in depression scores and headache frequency, highlighting the importance of recognizing and monitoring changes in depressive symptoms, in addition to headache frequency and functional impairment, when evaluating response to preventive medications.
