Pediatric Long COVID has been associated with a wide variety of symptoms, conditions, and organ systems, but distinct clinical presentations, or subphenotypes, are still being elucidated. In this exploratory analysis, we identified a cohort of pediatric (age <21) patients with evidence of Long COVID and no pre-existing complex chronic conditions using electronic health record data from 38 institutions and used an unsupervised machine learning-based approach to identify subphenotypes. Our method, an extension of the Phe2Vec algorithm, uses tens of thousands of clinical concepts from multiple domains to represent patients' clinical histories to then identify groups of patients with similar presentations. The results indicate that cardiorespiratory presentations are most common (present in 54% of patients) followed by subphenotypes marked (in decreasing order of frequency) by musculoskeletal pain, neuropsychiatric conditions, gastrointestinal symptoms, headache, and fatigue.

OBJECTIVES/OBJECTIVE:Numerous real-world evidence (RWE) guidance documents have been published by many regulatory agencies, health technology assessment agencies, and academic groups.These guidances are largely focused on generating unbiased treatment effect estimates from real-world data (RWD) for use in approval and coverage decisions. One of the most prominently cited documents, is a joint ISPOR/ISPE Task Force guidance on the use of RWD for Hypothsis Evaluating Treatment Effectiveness (HETE) Studies. However there are a variety of uses of RWD that existing guidance does not explicitly address. Our goal was to assess existing guidance for its relevance to a range of non-HETE analyses. METHODS:In this paper, we delineate categories of non-HETE applications of RWD. This range of applications includes various types of non-HETE RWD analyses as well as the use of RWD as inputs into other types of analyses such as health economic modeling or simulation studies that are not typically considered RWD studies. We then map existing guidance documents to the categories of non-HETE studies to help identify existing resources for analysts interested in conducting these types of analyses. RESULTS:We identified 13 published guidance documents for detailed review, including documents that outline best practices, provide checklists, or are structured templates. They were selected for their prominence, recency, specific reference to "fit-for-purpose" RWE generation, or their relevance to specific analysis categories. CONCLUSIONS:We conclude that existing guidance documents, even though they were largely developed for HETE studies, are highly useful for the broad range of non-HETE RWD analyses as well.

Racial/ethnic disparities in COVID-19 morbidity and mortality are serious in the United States, particularly among African American/Black and Latine (AABL) populations. Staying up-to-date on COVID-19 vaccination is essential for mitigating risk, but AABL vaccination rates are low. The present qualitative study explores perspectives on COVID-19 among AABL persons at high-risk for exposure to the SARS-CoV- 2 virus: frontline essential workers engaged in public-facing professions (e.g., retail). From a larger study of AABL frontline essential workers not up-to-date on COVID-19 vaccination, N = 50 participants were purposively sampled for maximum variability. Participants engaged in semi-structured qualitative interviews in English or Spanish that were audio-recorded, professionally transcribed, and translated into English as needed. Data were analyzed using a directed content analysis approach that was both inductive and theory-driven. Participants were 37 years old, on average, and most (65%) were men. Approximately half (56%) were Latine/Hispanic and 44% were African American/Black. Occupations included food preparation (40%), retail (28%), construction (12%), in-home health care (8%), and building maintenance and personal services (12%). Approximately a third (38%) had received ≥ 1 COVID-19 vaccine dose. We found COVID-19 vaccination perspectives were grounded in a larger context of medical and institutional distrust and past/ongoing systemic racism. In this context, results were organized into the following themes: general perspectives on COVID-19; barriers/facilitators related to race/ethnicity, social class, and community; specific aspects of the COVID-19 vaccine as barriers; mandates, incentives, and pressures to be vaccinated; and mixed effects of public health initiatives. Overall, participants were knowledgeable about COVID-19. Social norms reduced vaccine intentions but altruism and community/family concern could motivate it. Aspects of the public health response (e.g., advertisement campaigns targeting AABL populations) increased distrust and reduced vaccination willingness. However, at least some ambivalence about vaccination was common (participants would consider it). Yet there was a large gap between considering and receiving vaccination. Thus, barriers to COVID-19 vaccination for AABL frontline essential workers operate at multiple levels of influence, but are addressable. The present study yields recommendations to improve vaccination, including increasing the trustworthiness of systems and institutions, reducing systemic/structural barriers, harnessing social forces, and engaging AABL communities in program planning.

PURPOSE/OBJECTIVE:Patient/parent perceptions of poor-quality prognostic disclosure have not been well described, and these data offer important lessons to shape clinical practice and communication skills training. In this study, we aimed to characterize patient/parent negative experiences with prognostic communication to inform future efforts to improve how clinicians disclose prognosis. PATIENTS AND METHODS/METHODS:Semistructured interviews were conducted with a purposeful sample of pediatric cancer patients (n = 25) and parents (n = 40) across different timepoints in the progressive illness course extending into bereavement. Interviews were audio-recorded, transcribed, and de-identified for rapid qualitative analysis, in which multiple analysts used a standardized episode summary template to extract raw data specific to patient/parent narratives about prognostic disclosure experiences. Analysts engaged independently and collaboratively as a team in reflexive memo writing to identify negative experiences with prognostic communication, followed by team discussion to generate concepts and synthesize those concepts into themes. RESULTS:More than half of participants (59%) described negative experiences with prognostic disclosure, with parents highlighting distressing communication experiences more often than patients (parents: 32/40, 80% vs. patients: 6/25, 24%). Across patient/parent narratives, three main themes underpinned the perception of poor-quality prognostic communication: (1) insufficient information, (2) overwhelming or contradictory information, and (3) absence of person-centered connection. CONCLUSION/CONCLUSIONS:Many patients/parents perceived prognostic disclosure to be suboptimal and identified specific features underpinning poor-quality prognostic communication. These findings will inform future collaborative research with patients, parents, and multidisciplinary clinicians to codesign an intervention that individualizes prognostication to align with patient/parent preferences for receiving information and fostering connection.

OBJECTIVE:Demonstrate a successful laparoscopic removal of endometriosis from within the inguinal canal via a step-by-step video explanation, underscore the importance of pre-operative MRI imaging, and provide education on anatomy and surgical technique. DESIGN/METHODS:Video case presentation of a successful laparoscopic removal of endometriosis from within the inguinal canal. SUBJECTS/METHODS:A single patient with MRI imaging revealing endometriosis invasion into the inguinal canal and local vasculature. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. EXPOSURE/METHODS:The patient's abdomen was entered and vasculature was identified to prevent major bleeding. Appropriate exposure was achieved by transecting the round ligament to provide a landmark for the inguinal canal. The endometriosis was identified and dissected off the external iliac vasculature and the abdominal wall using the squeeze technique. The endometriosis was then dissected out of the inguinal canal, off the femoral artery, and then removed from the abdomen. Post-operatively, the patient was started on norethindrone acetate to suppress any residual disease and prevent recurrence. MAIN OUTCOME MEASURE/METHODS:Patient's pain and quality of life post-operatively. RESULTS:The patient noted immediate pain relief in the recovery room. One year post-operatively, the patient continued to endorse pain relief and no signs of hernia. CONCLUSION/CONCLUSIONS:Inguinal canal endometriosis is of rare occurrence. It typically presents as a groin lump or pain that is worse with menstruation. As the endometriosis is in close proximity to the abdominal wall and local vasculature, MRI imaging, as well as general surgery and vascular surgery consultation, are necessary for proper surgical planning. These are difficult operations that require proper understanding of pelvic and inguinal canal anatomy.

BACKGROUND:Limited literature exists on labor and delivery outcomes after bariatric surgery. This study assesses the impact of prior bariatric surgery on peripartum outcomes. METHODS:We queried the National Inpatient Sample (2016-2020) for labor and delivery admissions, categorizing them into three cohorts: prior bariatric surgery (BaS), obesity without prior bariatric surgery, and controls without obesity. We used a multivariate regression model, adjusting for confounders, to compare peripartum outcomes. RESULTS:We identified 22,685 BaS cases, 2.1 million pregnant controls with obesity, and 16.37 million pregnant controls without obesity. Compared to controls with obesity, the BaS cohort had lower rates of cesarean delivery [43% vs 46.8%, adjusted odds ratio (aOR) 0.72, p < 0.001], fetal distress [aOR 0.79, p < 0.001), post-partum hemorrhage (aOR 0.67, p < 0.001), fetal disproportion (aOR 0.36, p < 0.001), and premature rupture of membranes (aOR 0.88, p = 0.04). Compared to controls without obesity, the BaS group had higher rates of cesarean delivery (43% vs 29.57%, aOR 1.43, p < 0.001), breech presentation (aOR 1.4, p < 0.001), thromboembolic events (aOR 2.47, p = 0.01), and pregnancy termination (aOR 1.59, p = 0.048), but lower rates of assisted delivery (aOR 0.54, p < 0.001), fetal disproportion (aOR 0.56, p = 0.025), PROM (aOR 0.87, p = 0.024), and placenta previa (aOR 0.63, p = 0.019). The BaS group had longer hospitalizations (3.11 vs 2.56 days, p < 0.001) and higher hospitalization charges ($25,941 vs $20,760, p < 0.001) compared to controls without obesity. CONCLUSION/CONCLUSIONS:Pregnancy after bariatric surgery is associated with lower odds of cesarean delivery and postpartum complications, relative to the general population with obesity. This underscores the positive impact of bariatric surgery on peripartum outcomes.

Seizures associated with low-grade tumors in pediatric patients can be drug resistant and associated with significant morbidity. There are several low-grade tumor types associated with epilepsy in this population with the majority localized to the temporal lobe and some extra-temporal locations (frontal, parietal, and occipital lobes). The primary treatment of low-grade epilepsy-associated tumors is surgical resection, though the surgical approach and the use of intraoperative techniques remain controversial. Newer treatments are under investigation as primary and/or adjunctive therapy, including non-invasive surgical options and gene-targeted therapy. A multimodal approach to treatment may improve long-term outcomes and quality of life.

OBJECTIVE:The purpose of this study is to characterize patients who work professionally as musical performers and undergo potassium titanyl phosphate (KTP) laser ablation of vocal fold lesions in the outpatient setting. METHODS:A retrospective chart review of patients who are vocal performers and underwent in-office KTP laser ablation of benign vocal fold lesions at a single academic institution between 2012 and 2023 was conducted. Demographics including occupation, were descriptively reviewed. Acoustic measures, including cepstral peak prominence (CPP) and mean fundamental frequency variance (F0CoV), were analyzed. Vocal fold vibratory amplitude and mucosal wave were evaluated on videostroboscopy utilizing the voice vibratory assessment with laryngeal imaging. Preablation and postablation outcome measures were compared via Wilcoxon signed rank and McNemar's test. RESULTS:26 patients who identified as singers successfully underwent single-treatment in-office KTP laser ablation of vocal fold polyps. Ten patients (38.5%) identified as professional performers, and all patients continued their occupation after ablation. 84.2% of patients had either complete recovery or mildly reduced mucosal wave and amplitude of the treated vocal fold following KTP laser ablation. Additionally, CPP vowel improved following in-office KTP laser ablation, and F0CoV decreased following the ablation. All patients were able to continue their occupation in the same capacity. CONCLUSION/CONCLUSIONS:In-office KTP ablation is a valuable, safe, and feasible intervention for professional performers with benign vocal fold polyps. This study provides insight into vocal outcomes in the largest cohort of professional performers with apt follow-up.
