Objective Patients with chronic illness share their experiences in online communities and generate rich data on pain management. This study applied natural language processing methods, including large language models (LLMs), to Reddit discussions from lupus communities to characterize multidimensional pain experiences framed in the biopsychosocial model. Methods We extracted Reddit posts from the r/Lupus and r/LupusSupport subreddits posted from June 9, 2010, through December 31, 2023. Pain‐related posts were identified using a clinically informed pain lexicon. Topic modeling was used to identify thematic patterns, which were then compared with structured summaries generated by LLM instructions that were fine‐tuned using the biopsychosocial model of pain. Two reviewers conducted content analysis of the LLM‐generated summaries, evaluating thematic accuracy and coverage. Results Data from Reddit included 31,785 posts from 10,857 authors. We identified common pain complaints, management strategies, and sociocultural, affective, and nociplastic dimensions of pain. Instruction fine‐tuned LLMs produced structured summaries with an average thematic accuracy score of 3.1 of 4 (kappa = .09) and content coverage score of 2.9 of 4 (kappa = .38). Sociocultural features presented in 123 posts (33.8%), including peer support and validation (n = 106) and provider interactions or access issues (n = 35). Nociplastic pain presented in 205 posts (56.3%). Conclusion Natural language processing methods can be used to extract rich, multidimensional insights into pain experiences from online communities focused on lupus. These approaches highlight the psychological, social, and cultural facets of pain that may be underrepresented in clinical settings, supporting more patient‐centered approaches to care in rheumatology.

Background Immune-related adverse events (irAEs) remain largely unpredictable, potentially affecting multiple organ systems and occurring at almost any point during and even occasionally after immune checkpoint inhibitor (ICI) treatment. To identify populations at risk for these immune-mediated toxicities, we analyzed genetic characteristics and immune markers associated with clinically significant irAEs. Methods We carried out a genome-wide association study on 373 white patients receiving ICI treatment. We identified single nucleotide polymorphisms associated with irAEs. Blood cytokine profiling and peripheral blood mononuclear cell RNA sequencing were performed at pretreatment baseline and 6–8 weeks after ICI initiation. Findings were validated in two external cohorts. Results We identified genetic haplotypes in VWA8 (Von Willebrand Factor A Domain Containing 8) , OSBPL6 (Oxysterol Binding Protein Like 6), and ADAMTS9-AS2 (ADAM Metallopeptidase With Thrombospondin Type 1 Motif 9 Antisense RNA 2) associated with grade ≥2 irAEs. Patients carrying risk haplotypes for one or more genes exhibited significantly greater rates of grade ≥2 (OR 3.02; 95% CI 1.83 to 5.02; p<0.001), grade ≥3 (OR 3.59; 95% CI 1.93 to 6.64; p<0.001), and multiple type irAE (OR 2.60; 95% CI 1.53 to 4.39; p<0.001). Serum CCL3 levels were significantly elevated in individuals carrying risk haplotypes (p=0.03). Gene expression analysis demonstrated activated autoimmune and inflammatory pathways in the genetic risk group. Conclusions Novel polymorphisms in VWA8, OSBPL6, and ADAMTS9-AS2 may impact immune pathways, promote inflammation, potentiate autoimmune phenotypes, and convey risk of irAE in ICI-treated patients.

Abstract Introduction Obesity, defined as an elevated Body Mass Index (BMI) &gt;30, is a prevalent public health concern with far-reaching implications for various medical procedures and outcomes. In the context of inflatable penile prosthesis placement (IPP), where patient well-being and surgical success are of paramount importance, the impact of obesity on postoperative and intraoperative complications warrants thorough investigation. Objective Our study aimed to investigate the impact of BMI on both postoperative and intraoperative complications in an international, multi-institutional cohort of patients who underwent IPP placement. Methods We performed a retrospective chart review of 4398 cases. These cases were divided into two distinct groups based on BMI: less than 30 (n = 2260) and greater than or equal to 30 (n = 2138). The study assessed various surgical factors as well as complications, including overall complications, corporal scarring, incontinence, intraoperative complications, proximal perforation, distal perforation, proximal crossover, distal crossover, and urethral injury. Results Our analysis revealed that there were no statistically significant differences in intraoperative or postoperative complications between the two BMI categories. Notably, proximal corporal measurement was significantly higher for &gt;30 BMI group (9.55 +/−2.18) compared to &lt;30 BMI group (9.14 +/−2.19), (p = &lt; 0.001). The incidence rates for overall complications (30.2% vs. 28.7%; p = 0.164), corporal scarring (18.2% vs. 16.7%; p = 0.36), incontinence (3.53% vs. 3.13%; p = 0.076), intraoperative complications (1.94% vs. 1.68%; p = 0.253), and specific complications all exhibited no significant differences. Similarly, post-operative complications, including both non- infectious (6.99% vs. 6.22%; p = 0.215) and infectious (2.61% vs. 1.87%; p = 0.165) complications, did not significantly vary between BMI categories. Conclusions Our findings indicate that BMI does not exert a statistically significant influence on postoperative and intraoperative complications in the context of high-volume prosthetic urology. In the absence of any other differences between patients of differing BMIs, surgeons may need to be mindful of pump tubing length concerns in obese patients.

Introduction: Conditions that disrupt the adrenal glands' typical function are known as adrenal gland ailments or diseases. This study examines the distribution of adrenal disorders across various demographic and geographic groups in the United States, including gender, census region, race, age groups, and urbanization levels. Our objective was to identify disparities and trends to inform targeted interventions and resource allocation. Methods: From 1999 to 2020, mortality statistics for adrenal diseases were extracted from the CDC-WONDER database. Age, sex, race, location, urbanization status, and place of death were used to stratify the age-adjusted mortality rates (AAMRs) and crude mortality rates (CMRs) per 100,000. We calculated the average annual percentage change (APC) using Joinpoint regression software. Results: A total of 31,028 fatalities were reported due to adrenal disorders from 1999-2020 (AAPC: 1.277; 95% CI, -0.032 to 2.6032, p=0.055916). An initial rising trend was observed from 1999-2003 (APC: 2.4799), followed by a declining trend from 2003-2013 (APC: -3.0094), then a modest rise from 2013-2018 (APC: -0.9188), and finally a sharp increase from 2018-2020 (APC: 2.9445). Males had a higher AAMR (6.8) than females (6.4). The West census region had the highest AAMR (7.2), followed by the Midwest (7.1), South (6.3), and Northeast (5.6). The highest crude mortality rate was observed in individuals aged 85+ years (52.2). Several disparities were noted when stratified by urbanization and race, including the highest AAMR in Non Core (Nonmetro) regions (7.9) and among American Indian or Alaska Native populations (8.2). The highest percentage of deaths occurred in medical facilities. Conclusions: The findings underscore the need for tailored public health strategies to address disparities in adrenal disorders among vulnerable populations. Specific attention should be directed towards the male gender, West census region, American Indian or Alaska Native populations, and the geriatric population. Future research should explore underlying causes and interventions to mitigate these disparities. Presentation: Monday, July 14, 2025

Background Antibiotic use may alter gut microbiota, which could be associated with various diseases, including cardiovascular disease (CVD). Accordingly, further epidemiological evidence is needed to clarify the potential risk of CVD associated with antibiotic exposure. We evaluated the association between long‐term antibiotic exposure and CVD risk in South Korea. Methods and Results This nationwide retrospective cohort study used data from the Korean National Health Insurance Service database. A total of 2 159 965 individuals aged 40 to 79 years who had no history of antibiotic prescriptions from 2004 to 2005 were included and followed through December 31, 2021. Antibiotic exposure was defined as the cumulative days of antibiotic prescriptions from 2006 to 2010. The primary end point was incident CVD with 2 or more days of hospitalization from 2011 to 2021. Adjusted hazard ratios (aHR) and 95% CIs for CVD according to antibiotic exposure were estimated using multivariable Cox proportional hazards models, adjusting for a range of covariates. Longer cumulative antibiotic prescription days were associated with an increased risk of CVD. The aHRs for CVD associated with 1 to 14, 15 to 90, 91 to 180, 181 to 364, and ≥365 days of antibiotic exposure were 0.98 (95% CI, 0.96–1.01), 1.01 (95% CI, 0.99–1.03), 1.05 (95% CI, 1.03–1.08), 1.06 (95% CI, 1.04–1.09), and 1.10 (95% CI, 1.07–1.13) compared with those with no antibiotic prescriptions. Conclusions In this large population‐based cohort study of Korean adults, long‐term antibiotic exposure may be associated with a higher risk of CVD. Further research is warranted to establish causality and elucidate the underlying mechanisms for this association.

Stereotactic radiosurgery was associated with a higher obliteration rate compared with embolization in patients with eloquent brain arteriovenous malformations, whereas there was no evidence of a difference in functional outcomes or complications after adjustment.

Mutations in BRCA1 and BRCA2 genes, whether inherited or somatically acquired, cause homologous recombination deficiency (HRD) in tumor cells. The timing of HRD onset in the emerging tumor lineage is unknown. Here, we present HRDTimer, an algorithm to infer the onset of HRD-driven mutagenesis prior to cancer diagnosis. We estimate that HRD arises at 34% of SBS1-based molecular time---corresponding to a median of 8.3 years (IQR 7.1--10.4) prior to diagnosis in triple-negative breast cancers, and 15.0 years (IQR 12.0--20.6) in ER-positive breast cancers. Bulk sequencing reveals accelerated SBS1 accumulation following neoplastic transformation compared to normal tissue, influencing the estimated age of HRD onset. Single-cell duplex sequencing confirms SBS1 acceleration in tumors and further shows that non-tumor cells largely lack the HRD signature, indicating that HRD is rare in pre-malignant cells, even in BRCA1/2 mutation carriers. Together, our analysis pinpoints the onset of HRD before diagnosis, defining a window for detection and potential interception.

Introduction: Excess sodium intake is strongly linked with hypertension and cardiovascular disease (CVD); people with narcolepsy (PwN) have increased CV risk. Hypothesis: Switching from high-sodium oxybate (SXB; Xyrem ® ; 6–9 g for ≥6 wks) to low-sodium oxybate (LXB; Xywav ® ; same regimen) reduces mean 24-hr ambulatory systolic blood pressure (ASBP) after ≈6 wks in PwN, regardless of antihypertensive (anti-HTN) use and site type. Methods: XYLO, an open-label, single-arm study (NCT05869773), assessed PwN aged 18−70 y with office SBPs of 130−155 mmHg. The primary and key secondary endpoints were changes from baseline (BL) to end-of treatment (EOT) in mean 24-hr ASBP and seated resting (“office”) SBP (OSBP), respectively; exploratory endpoints were diastolic BP (DBP) changes. Changes are baseline adjusted. Prespecified subgroup analyses explored BL anti-HTN use and participation site (ie, site-based [at study site] vs decentralized [at-home]). Results: In 43 PwN (mean age, 45 y; female, 65%; anti-HTN, 33%), mean±SD BL OSBP and DBP were 138.0±5.7 and 85.2±6.6 mmHg, respectively. Mean±SD total SXB vs LXB dosages were 8.0±1.1 vs 8.1±1.1 g/night, reflecting 1457±206 vs 118±16 mg sodium (difference: ≈1339 mg); median 24-hr urinary sodium was 4232 mg/d at BL and 2703 mg/d at EOT (median change: 1288 mg/d). Mean change in 24-hr ASBP (least squares mean [95% CI]) was −4.1 (−6.9, −1.4; 1-sided P =0.0019) mmHg (Fig 1) ; mean change in OSBP was −9.2 (−11.9, −6.5; 1-sided P <0.0001). Mean changes in 24-hr ambulatory and office DBP were −2.3 (−4.1, −0.5; 2-sided P =0.0118; nominal) and −3.8 (−6.0, −1.6; 2-sided P =0.0014; nominal) mmHg, respectively. In subgroups, mean change in 24-hr ASBP was −4.6 (−9.6, 0.3) mmHg with BL anti-HTN use and −3.9 (−7.3, −0.5) mmHg without BL anti-HTN use; changes in OSBP were −11.8 (−16.5, −7.1) and −7.9 (−11.1, −4.6) mmHg. Mean change in 24-hr ASBP was −3.6 (−8.0, 0.9) mmHg for site-based and −4.5 (−8.1, −1.0) mmHg for decentralized participation. Corresponding changes in OSBP were −9.0 (−13.3, −4.6; site-based) and −9.3 (−12.8, −5.8; decentralized) mmHg with a downward trend over 6 wks ( Fig 2 ). Treatment-emergent adverse events (all mild/moderate) occurred in 40% of PwN (N=67). Conclusions: Switching from SXB to LXB reduced daily medication-related sodium intake in PwN and was associated with clinically meaningful BP reductions overall and across subgroups, consistent with evidence on dietary and medication-related sodium effects.

ABSTRACT Background Advanced therapies increase the risk of shingles in inflammatory bowel diseases (IBD). Aim To compare the risk of shingles with different advanced therapies in patients with IBD. Methods We identified patients with IBD who initiated treatment with tumour necrosis factor (TNF) antagonists, anti‐integrins, anti‐interleukins, Janus kinase (JAK) inhibitors, or sphingosine‐1 phosphate receptor (S1PR) modulators between 2016 and 2022 and had follow‐up for at least 1 year before and after treatment initiation. We estimated the incidence rate (IR per 100 person‐year [PY]) of shingles (overall and complicated) and compared the risk with different advanced therapies through multinomial propensity score‐based inverse probability of treatment weighting (IPTW), with propensity scores estimated through generalised boosted models, accounting for disease characteristics, healthcare utilisation, comorbidities and prior and concomitant medications. Weighted Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for multiple treatment comparisons. Results We included 21,675 patients followed over 27 months. IRs per 100 PY of shingles and complicated shingles were: TNF antagonists 1.0/0.3, anti‐integrin agents 1.4/0.4, anti‐interleukins 1.2/0.5, JAK inhibitors 3.3/0.9 and S1PR modulators 2.0/1.0. After adjusting for confounding variables, JAK inhibitors were associated with higher risks of shingles than TNF antagonists (HR 2.19; 1.28–3.75), anti‐integrins (HR 1.87; 1.12–3.14) and anti‐interleukins (HR 1.70; 0.98–2.96). Conclusions JAK inhibitors were associated with 1.7–2.2‐fold higher risk of shingles than other advanced therapies.

BACKGROUND: People with narcolepsy are at increased risk for hypertension and cardiovascular disease; excessive sodium intake is linked to both. METHODS: We studied patients with narcolepsy and office systolic blood pressures (BPs) of 130 to 155 mm Hg taking twice-nightly high-sodium oxybate for ≥6 weeks who switched to low-sodium oxybate at the same dosage. The primary end point was the change from baseline in mean 24-hour ambulatory systolic BP at the end of treatment (≈6 weeks after switching). Secondary and exploratory end points included changes in diastolic BP, office BP, and 24-hour sodium excretion. RESULTS: Patients (n=43) had a mean age of 45 years, were 65% female, 33% on antihypertensives, with baseline mean (SD) office BP of 138.0/85.2 (5.7/6.6). Mean (SD) total high- and low-sodium oxybate dosages of 8.0 (1.1) and 8.1 (1.1) g/night, respectively, represented 1456.5 (206.2) and 117.8 (16.3) mg of sodium. The median 24-hour urinary sodium was 4278 mg/d at baseline and 2703 mg/d at the end of treatment (median change, 1288 mg/d). Mean (SE) 24-hour ambulatory systolic BPs at baseline and study end were 132.3 (1.8) and 128.2 (1.8) mm Hg (least-squares mean change, −4.1 [95% CI, −6.9 to −1.4] mm Hg; 1-sided P =0.0019). BP changes by narcolepsy subtype, sex, body mass index, baseline office BP, and baseline antihypertensive use were consistent with the overall effect size. CONCLUSIONS: People with narcolepsy switching from high- to low-sodium oxybate showed substantially reduced daily medication-related sodium intake and significant 24-hour BP reductions. These results demonstrate the importance of reducing pharmaceutical sodium content in this elevated cardiovascular risk patient population.
