e16076 Background: Gastric cancer is the fourth leading cause of global cancer deaths. Despite declining incidence and mortality, it remains a significant contributor to the global disease burden. This study analyzes regional gastric cancer DALYs and mortality trends from 1990-2021 using the GBD database. Methods: The regional DALYs and mortality rates per 100,000 individuals aged 70+ from GBD 2021 were analyzed, with trends from 1990 to 2021 evaluated using AAPC, and statistical significance assessed by p-values. Results: In 2021, the greatest Age-standardized DALYs rates were recorded in Andean Latin America, with 3068.04 per 100,000; the lowest was found in High-income North America with 386.08 per 100,000. The most significant increase of DALYs rate from 1990 to 2021 was in Southern Sub-Saharan Africa, (AAPC = -0.3068%; 95% CI: -0.3852 to -0.2234; p < 0.000001), while in Western Europe, the largest decline was noted (AAPC = -2.9999%; 95% CI: -3.0164 to -2.9841; p < 0.000001). Andean Latin America was the region with the highest Age-standardized mortality rates (ASMRs) in 2021, at 207.58 per 100,000 while High-income North America had the lowest at 27.18 per 100,000. In Western Sub-Saharan Africa, the ASMRs were rising with an AAPC of -0.2601% (95% CI: -0.2872 to -0.2368; p < 0.000001), while Western Europe had the highest decline with an AAPC of -2.7658% (95% CI: -2.7895 to -2.7471; p < 0.000001). Conclusions: The global burden of diseases from 1990 to 2021 is regional in nature. In 2021, DALYs and mortality were predominantly high in Andean Latin America and East Asia and notably low in High-income North America. DALYs have risen across Southern Sub-Saharan Africa over three decades, and mortality increased over Western Sub-Saharan Africa, while both declined sharply in Western Europe. These trends underscore the importance of regionalized health solutions. DALY per 100,000.

Managing persistent atrial fibrillation (AF) remains challenging due to its complex arrhythmic substrate, and pulmonary vein isolation through catheter ablation remains the primary treatment. This meta-analysis aims to compare the efficacy and safety outcomes of cryoballoon ablation (CBA) and radiofrequency ablation (RFA) in patients with persistent AF to provide evidence-based insights for clinical decision-making. A systematic search of PubMed, Embase, and Cochrane Central was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) comparing CBA and RFA in persistent AF were included. Data on efficacy, safety, and procedural outcomes were pooled in the form of odds ratios (ORs) or mean differences (MDs) with corresponding 95% confidence intervals (CIs) using the random effects model in the Review Manager (RevMan) software. Four RCTs comprising 899 patients were included in our analysis. There were no significant differences between CBA and RFA in terms of AF recurrence, atrial tachycardia/flutter recurrence, or any arrhythmia recurrence during a mean follow-up period of 18 months after ablation. Procedure time was significantly shorter with CBA (MD: −44.85 minutes, 95% CI: −56.46 to −32.24, P < 0.01), while fluoroscopy time was comparable between the 2 groups (MD: 4.31 minutes, 95% CI: −1.79 to 10.40, P = 0.17). Safety outcomes, including overall complications, phrenic nerve palsy, access-site complications, and pericardial effusion, showed no significant differences between the 2 groups. CBA and RFA show similar rates of atrial arrhythmia recurrence and periprocedural complications in the treatment of persistent AF, while CBA offers the advantage of a shorter procedure time.

Abstract Aims Aortic regurgitation (AR) arises from leaflet disease and/or dilatation of the functional aortic annulus complex. Understanding the mechanisms of AR informs surgical planning of valve and aorta repair. This study investigates the mechanisms, aetiologies, and outcomes of isolated native severe AR in a consecutive cohort of patients. Methods and results Patients with moderate-to-severe (3+)/severe (4+) native valve AR, identified from our institutional echocardiography database (2014–2018), were included. Exclusions were significant concomitant valve disease, endocarditis, or aortic dissection. AR was classified per the El-Khoury system: Type I (normal leaflet motion: Ia–ascending aorta/sinotubular junction dilatation, Ib–aortic root dilation, Ic–aortic annular dilation), Type II (leaflet prolapse), and Type III (leaflet restriction). Valve anatomy and clinical outcomes, including mortality and surgical intervention, were analyzed. Of 282 patients (77.3% male), 58.5% had multiple AR mechanisms. Type II (leaflet prolapse) was most common (48.6%), followed by Type III (36.2%). Bicuspid aortic valve (BAV) represented 35.5% of the population, with leaflet prolapse observed in 72%. Multiple mechanisms were more frequent in BAV (77% vs. 48%, P &lt; 0.001). After a median follow-up of 4.7 years (available for 97.5% of patients), 158 (57.5%) underwent an intervention with 48.7% having an aortic valve repair or valve-sparing aortic root replacement. Conclusion Although leaflet prolapse (Type II) was the pre-dominant AR mechanism, multiple contributing mechanisms were often present, particularly in BAV patients. Aortic valve repair accounted for nearly half of surgical interventions, underscoring the importance of mechanism identification to optimize repair and avoid valve replacement.

Background: The safety and cost of concomitant atrial fibrillation (AF) ablation and left atrial appendage occlusion (LAAO) procedure remain unknown. Objective: The study sought to determine real-world outcomes of AF patients who underwent LAAO with ablation. Methods: The National Inpatient Sample and International Classification of Diseases–Tenth Revision codes were used to identify patients who underwent LAAO with and without AF ablation during the years 2016-2022. The outcomes assessed included procedural complications and resource utilization. Results: LAAO with AF ablation was associated with a higher rate of overall complications (odds ratio [OR] 1.54, 95% confidence interval [CI] 1.37-1.74), major complications (OR 1.38, 95% CI 1.18-1.60), non-home discharge (OR 1.55, 95% CI 1.23-1.96), prolonged length of stay >1 day (OR 3.21, 95% CI 2.92-3.52), and increased hospitalization costs as defined by median cost >$25,926 (OR 19.42, 95% CI 16.21-23.25) when compared to LAAO alone after adjustment for potential confounding variables. Patients who underwent LAAO with ablation were also more likely to receive pacemaker implantation (3.6 % vs 0.2%, P < 0.001) and experience acute kidney injury (3.9% vs 2.1%, P < 0.001) and non-ST elevation myocardial infarction (3.7% vs 1.5%, P < 0.001). Conclusion: In a large, contemporary, real-world study of LAAO procedures in the United States, concomitant AF ablation was associated with a higher rate of overall and major complications and an increased resource utilization.

ABSTRACTBackground and AimsWe aimed to assess the impact of setons on perianal fistula outcomes in patients with perianal fistulising Crohn's disease (PFCD) treated with anti‐TNF therapy.MethodsWe included patients treated with their first anti‐TNF therapy for PFCD after undergoing a pelvic MRI between 2005 and 2022 from 6 North American centres. Our exposure was one or more setons at the time of anti‐TNF therapy. Our primary outcome was major adverse fistula outcome (MAFO), a composite of repeat local surgical intervention, hospitalisation, or faecal diversion for PFCD, and our secondary outcome was fistula remission defined clinically. We used 1:1 cardinality matching and propensity score weighting to control for fistula severity based on centrally read MRIs, luminal characteristics, and concomitant therapies.ResultsOur analysis included 221 patients: 81 with setons and 140 without setons. After cardinality matching, our cohorts were balanced (standardised difference < 0.1 for all covariates). Patients with setons had similar rates of MAFO (HR 1.23; 95% CI, 0.68–2.21) and fistula remission at 6 months (OR, 0.81; 95% CI, 0.41–1.59) and 12 months (OR, 0.63; 95% CI, 0.31–1.27) compared to patients without setons. Our results remained stable when analysed by propensity score weighting and in a sensitivity analysis of patients who underwent an exam under anaesthesia. In patients with abscesses, there were lower rates of MAFO (HR, 0.49; 95% CI, 0.19–1.25) but not statistically significant in patients with setons.ConclusionsIn this multicentre, setons were not associated with improved fistula outcomes. Future prospective controlled studies are warranted.

ABSTRACT Background Cardiac implantable electronic device (CIED) infections are a serious complication associated with significant morbidity, mortality, and healthcare costs. Despite guideline recommendations for complete device removal, disparities in healthcare access and resource availability between urban and rural settings may influence patient outcomes. This study aims to evaluate rural–urban disparities in the management and outcomes of patients hospitalized with CIED infections. Methods A retrospective cohort analysis was conducted using the National Readmissions Database (NRD) from 2016 to 2021. Patients aged ≥ 18 years hospitalized with CIED infections were identified using ICD‐10 codes. Hospital location was categorized as urban or rural based on the Urban Influence Codes. Baseline characteristics, complications, and outcomes were compared using chi‐square and t ‐tests, and a multivariable logistic regression model was employed to assess the independent association of hospital settings with transvenous lead removal (TLR) utilization. Results A total of 288,402 patients were hospitalized for CIED infections, with 94.9% treated in urban hospitals and 5.1% in rural hospitals. Urban hospital patients had a higher prevalence of key comorbidities, including heart failure, valvular heart disease, atrial fibrillation and peripheral vascular disorders. In‐hospital mortality was significantly higher in urban hospitals (6.2% vs. 4.8%, p < 0.01) likely due to higher burden of comorbidities and higher rates of acute complications such as stroke (3.1% vs. 1.8%, p < 0.01) and systemic embolism (1.4% vs. 0.7%, p < 0.01). TLR was more frequently performed in urban hospitals (20.1% vs. 9.6%, p < 0.01), with rural hospitals exhibiting 59% lower odds of receiving TLR (OR: 0.41, 95% CI: 0.36–0.47, p < 0.01). TLR was associated with reduced in‐hospital mortality, 30‐day mortality, and 30‐day readmission rates across both hospital settings. Conclusion Our study highlights significant rural–urban disparities in CIED infection management. Despite rural hospitals admitting patients with a lower comorbidity burden, TLR utilization was significantly lower, potentially due to limited access to specialized expertise and procedural resources. Given TLR's association with improved survival and reduced readmissions, regardless of the hospital setting, targeted interventions are needed to enhance access to specialized care in rural settings. Further research is warranted to explore strategies for bridging these disparities and optimizing CIED infection outcomes nationwide.

Importance High-quality evidence regarding suppressive valacyclovir treatment in herpes zoster ophthalmicus (HZO) is necessary to guide care. Objective To determine whether suppressive valacyclovir compared with placebo delays the occurrence of new or worsening stromal keratitis (SK), endothelial keratitis (EK), iritis, or dendriform epithelial keratitis (DEK) during 12 months of treatment and if treatment benefit persisted at 18 months (secondary end point). Design, Setting, and Participants The Zoster Eye Disease Study (ZEDS) was a randomized clinical trial conducted in 95 sites from November 2017 to June 2024. Immunocompetent, nonpregnant adults with a history of an HZO rash, documented active keratitis or iritis within 1 year, and an estimated glomerular filtration rate of 45 mL/min/1.73 m 2 or greater were eligible. After determined to be eligible, participants were randomized in 4 strata: age at onset (&amp;lt;60 years vs ≥60 years) and disease duration (&amp;lt;6 months vs ≥6 months). Interventions A total of 12 months of double-masked daily valacyclovir, 1000 mg, or placebo. Main Outcomes and Measures The primary outcome was time to first occurrence within 12 months of new or worsening SK, EK, iritis, or DEK. Results A total of 527 participants (median [IQR] age, 60 [50-68] years; 266 female [50.5%]; 266 in the valacyclovir group; 261 in the placebo group) were randomized in 4 strata; 481 completed 12 months, and 460 completed 18 months. Data were analyzed by intention to treat. At 12 months, primary end points occurred in 86 participants (33%) assigned to placebo and 74 (28%) assigned to valacyclovir, and at 18 months in 104 participants (40%) assigned to placebo and 86 (32%) assigned to valacyclovir. The hazard ratio (HR) of the primary end point at 12 months was 0.77 for participants taking valacyclovir vs placebo (HR, 0.77; adjusted 95% CI, 0.56-1.05; P = .09) and 0.73 at the secondary end point at 18 months (HR, 0.73; adjusted 95% CI, 0.55-0.97; P = .03). There was a reduction of multiple other secondary end points at 12 months (HR, 0.70; 95% CI, 0.52-0.95; P = .02) and 18 months (HR, 0.72; 95% CI, 0.55-0.95; P = .02). Conclusions and Relevance Although the primary outcome did not show a benefit of suppressive valacyclovir treatment, secondary study outcomes showed treatment superiority at the 18-month end point and reduced number of multiple episodes of keratitis or iritis at both 12 and 18 months. These results support consideration of 1 year of suppressive valacyclovir treatment for HZO. Trial Registration ClinicalTrials.gov Identifier: NCT03134196

Importance Evidence regarding suppressive valacyclovir treatment on postherpetic neuralgia is necessary to guide care. Objective To test the hypothesis that suppressive treatment with 1000 mg/d of oral valacyclovir for 12 months reduces the prevalence, severity, and duration of postherpetic neuralgia compared with placebo at 12 and 18 months in participants with herpes zoster ophthalmicus (HZO). Design, Setting, and Participants Multicenter, placebo-controlled randomized clinical trial including 527 immunocompetent, nonpregnant adults with history of HZO rash, documented keratitis, or iritis within 1 year and an estimated glomerular filtration rate of 45 mL/min/1.73 m 2 or greater. The study was conducted at 95 participating sites (in Canada, New Zealand, and the US) from November 2017 to June 2024 and participant visits occurred every 3 months. Intervention Treatment with 1000 mg/d of valacyclovir or placebo for 12 months. Main Outcomes and Measures Prevalence of postherpetic neuralgia, severity as determined by pain score (a score of ≥3 on a scale of 1-10), pain duration (≥3 months after HZO onset), and total daily dose of pain medication. Results Of the 527 participants (490 completed 12 months of treatment and 460 completed 18 months), 73 (14%) had postherpetic neuralgia and were analyzed by age at HZO onset (&amp;lt;60 years or ≥60 years) and disease duration (recent [&amp;lt;6 months] or chronic [≥6 months]). Of the 73 participants with postherpetic neuralgia (34 in the valacyclovir group and 39 in the placebo group), the mean age was 62.4 years (SD, 13.6 years), 59% were female, 5% were Black or African American, and 10% were Hispanic. The prevalence of postherpetic neuralgia at 12 months was not reduced by valacyclovir (12/32 [38%]) compared with placebo (14/35 [40%]) (between-group difference, 2.5% [95% CI, −20.8% to 25.8%]; P &amp;gt;.99). The participants who were younger than 60 years at HZO onset and had a chronic disease duration had lower pain scores in the valacyclovir group (mean score, 0.3 [SD, 0.9]) vs the placebo group (mean score, 0.8 [SD, 1.9]) at 12 months ( P = .045) and at 18 months (mean score, 0.2 [SD, 0.9] vs 1.0 [SD, 2.3], respectively; P = .02). There was a decrease in pain duration in the valacyclovir group at 18 months (mean, 13.6 [SD, 11.4] months) vs the placebo group (mean, 18.7 [SD, 29.5] months) (linear mixed-effects model between-group difference, −3.39 months [95% CI, −6.73 to −0.04 months]; P = .046). The total daily dose of neuropathic pain medication was lower in the valacyclovir group (mean, 271.4 [SD, 593.8] mg/d) vs the placebo group (mean, 363.4 [SD, 592.2] mg/d) at 12 months (linear mixed-effects model P = .006) and at 18 months (mean, 209.0 [SD, 412.8] mg/d vs 286.2 [SD, 577.9] mg/d, respectively; linear mixed-effects model P = .01). Conclusions and Relevance One year of suppressive treatment with valacyclovir was associated with a lower dosage of neuropathic pain medication. Participants in the valacyclovir group, who were younger at HZO onset and had a chronic disease duration, had lower pain scores. These secondary outcomes support consideration of 1 year of suppressive treatment with valacyclovir to reduce dosage of pain medications and pain due to HZO.
