Importance A greater proportion of older patients (age ≥65 years) are undergoing thyroidectomy amidst an aging population. Given the elusive results in the literature, clarifying whether older patients face different thyroidectomy safety profiles is crucial for optimizing risk assessment and patient counseling. Objective To evaluate the association between older age (age ≥65 years) and thyroidectomy safety by comparing endocrine-related complications, including recurrent laryngeal nerve injury, hypocalcemia, hematoma, and mortality in older compared with younger patients. Data Sources Ovid MEDLINE, CINAHL, Ovid Embase, and the Cochrane Library were systematically searched from inception to May 29, 2025; only English-language studies were included. Study Selection Cohort studies comparing thyroidectomy outcomes between older and younger patients and reporting endocrine-related complications were included. Two independent reviewers screened abstracts and full texts. Of 3192 studies identified, 11 met inclusion criteria. Data Extraction and Synthesis Two independent reviewers extracted data following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Risk of bias across studies was evaluated using the ROBINS-I (Risk of Bias in Nonrandomized Studies of Interventions) tool. Random-effects models were used to pool data. Main Outcomes and Measures Incidence of recurrent laryngeal nerve injury, hypocalcemia, and hematoma; odds ratios (ORs) with 95% CIs were calculated. Results The analysis included 11 studies with a total of 427 886 patients of whom 104 232 (24.4%) were older adults (≥65 years). Older adults had greater odds of overall recurrent laryngeal nerve injury (2.3% vs 1.0%; OR, 1.58; 95% CI, 1.15-2.16; I 2 = 76%), hematoma (2.4% vs 1.0%; OR, 2.32; 95% CI, 1.70-3.16; I 2 = 0%), and mortality at last follow-up (0.3% vs 0.01%; OR, 11.09; 95% CI, 1.77-69.52; I 2 = 90%) compared with younger patients. However, rates of overall hypocalcemia (OR, 0.80; 95% CI, 0.61-1.05; I 2 = 71%) and wound complications (OR, 1.38; 95% CI, 0.92-2.06; I 2 = 0%) were similar. Conclusions and Relevance This systematic review and meta-analysis found that thyroidectomy is safe in older patients, with only small absolute increases in recurrent laryngeal nerve injury, hematoma, and mortality despite statistical significance. These findings support individualized counseling and perioperative planning while acknowledging the overall safety of thyroidectomy in this population.

Abstract Aims Heart failure (HF) continues to portend significant morbidity and mortality within the USA. Data regarding the efficacy of mineralocorticoid receptor antagonists (MRAs) in HF with preserved ejection fraction (HFpEF) remains unclear. Finerenone, a non-steroidal MRA, has demonstrated reduction in hospitalizations in this population. However, the comparative efficacy of different MRA classes in these patients remains elusive. Methods and results We conducted a retrospective observational cohort study using the TriNetX research network. We applied 1:1 propensity score matching (PSM) to compare patients with HFpEF initiated on finerenone vs. spironolactone. We examined 1-year risks of HF exacerbation, acute kidney injury (AKI), electrolyte derangements, and cardiovascular outcomes. We identified 254,417 patients with HFpEF and MRA use. After PSM, each cohort contained 491 patients. Analysis revealed that finerenone use was associated with a significantly lower risk of HF exacerbation (hazard ratio [HR] = 0.63 [95% confidence interval [CI]: 0.54, 0.74], P < 0.001), all-cause mortality (HR = 0.38 [95% CI: 0.23, 0.64], P < 0.001), and hypokalaemia (HR = 0.58 [95% CI: 0.40, 0.85], P = 0.001). The aforementioned results, along with a reduction in AKI risk, were statistically significant after stratified subgroup analysis by diabetes mellitus and chronic kidney disease. Conclusion In this large real-world HFpEF cohort, finerenone use was associated with lower risks of HF exacerbation and all-cause mortality compared with spironolactone. These observational findings are hypothesis-generating and warrant confirmation in randomized trials.

Background: Transradial artery access (TRA) is the favored approach for percutaneous coronary intervention (PCI) and coronary angiography (CAG). However, transulnar artery access (TUA) has emerged as an alternative, particularly when TRA is not feasible. This systematic review and meta-analysis aims to compare the efficacy and safety of TUA versus TRA in patients undergoing PCI and CAG. Methods: From inception to August 2025, a systematic search of electronic databases was conducted. Data were synthesized using a random-effects model, and heterogeneity was assessed using the I 2 statistic. Results: Nine RCTs involving 6089 patients were included. Meta-analysis revealed no significant difference in procedural success between TUA and TRA (RR: 0.93, 95% CI: 0.82–1.06, P = 0.28, I 2 = 99%). Similarly, puncture success rates were comparable (RR: 0.95, 95% CI: 0.91–1.00, P = 0.06, I 2 = 83%). Secondary outcomes showed no significant differences in puncture attempts or hematoma incidence, but TRA was associated with a shorter procedure time (MD: 0.89, 95% CI: 0.27–1.50, P = 0.005). Conclusion: TUA provides a viable alternative to TRA, with similar success rates and complication profiles. However, TRA remains superior in terms of procedure time. Further large-scale RCTs are warranted to confirm these findings and refine clinical guidelines.

Abstract Background Measurement of cardiac troponin (cTn) using high-sensitivity assays is recommended for the diagnosis of myocardial infarction. We determined sex-specific and uniform 99th percentile upper reference limits (URLs) using the new Elecsys® Troponin T high-sensitivity Gen 6 assay in a global, healthy reference range cohort. Methods Lithium-heparin plasma and serum samples were prospectively collected from apparently healthy individuals aged ≥20 years across 34 global sites in the United States, Europe, China, and Japan. cTnT was measured using the Troponin T high-sensitivity Gen 6 assay on the Cobas® e 801 analyzer. Exclusion criteria were defined according to the 2022 IFCC guidance. Uniform and sex-specific 99th percentile URLs and nonparametric 95% CIs were determined in plasma and serum separately and combined. Results The final study population comprised 4147 participants (52.5% female) with a median (25th–75th percentiles) age of 48.0 (33.0–59.0) years; 45.8%, 47.9%, 5.2%, and 1.1% were White, Asian, Black, and other/unknown, respectively. For sample matrices combined (n = 8294), 81.0% and 99.2% of cTnT values were above the limit of detection in females and males, respectively. Sex-specific 99th percentile URLs (95% CI) were 18 (16–23) ng/L for females and 32 (28–35) ng/L for males; the uniform 99th percentile URL was 27 (24–31) ng/L. URLs were comparable in plasma and serum samples. Conclusions This study determined sex-specific and uniform 99th percentile URLs for the Troponin T high-sensitivity Gen 6 assay that were comparable irrespective of the matrix used in a large, global, healthy reference population.

Abstract Background Ventricular arrhythmias (VAs) are a proximate mechanism of sudden cardiac death, yet national patterns in place of death (POD) and their determinants remain sparsely described. We quantified 25-year trends and factors associated with POD among UAs decedents in the United States. Methods We analyzed CDC WONDER Multiple Cause of Death data (1999–2024) for adults ≥25 years with ventricular arrhythmias (ICD-10 I47.2, I49.0) as underlying cause. POD was categorized as inpatient, outpatient/emergency department (ED), home, hospice/nursing, or other/unknown. Covariates included age, sex, race, Hispanic origin, and urbanization. We calculated Annual and Average Annual Percent Changes (AAPCs and APC) using Age-Adjusted Mortality Rates (AAMRs), and fit multinomial logistic regression (reference = inpatient) to obtain adjusted odds ratios (ORs, 95% CIs). Results Among 433,988 ventricular arrhythmia (VA) deaths, POD was inpatient 62.0%, outpatient/ED 18.1%, home 11.1%, hospice/nursing 5.8%, other 3.1%. Inpatient deaths increased from 57.8% (1999) to 66.1% (2024). AAMRs declined sharply from 13.3 per 100,000 in 1999 to 6.3–6.5 during 2010–2019, then rose to 7.4 in 2021 and fell to 6.8 in 2024. In home vs inpatient: ≥85 years, medium/small metropolitan counties and rural counties had higher odds of VA deaths, whereas younger age groups, females, Black, American Indian, Asian/Pacific Islander individuals and Hispanic individuals had lower odds. In outpatient/ED vs inpatient: 25–44 years, 45–64 years, males, Black, American Indian and Asian/Pacific Islander individuals had higher odds, whereas ≥85 years and females had lower odds. In hospice/nursing facilities: ≥85 years, females, Whites, non-Hispanic individuals, medium/small metropolitan counties and rural counties had higher odds of VA deaths, whereas younger age groups, Black, American Indian, Asian/Pacific Islander individuals and Hispanic individuals had markedly lower odds. Conclusion From 1999–2024, VA deaths shifted toward hospitals. Persistent disparities by age, sex, race/ethnicity, and rurality highlight the need to expand equitable advance care planning and device deactivation discussions.

Despite advances in percutaneous coronary procedures, in-stent restenosis remains a significant challenge. Although sirolimus- and paclitaxel-coated balloons are promising alternatives, their comparative safety and efficacy remain uncertain. PubMed, Embase, and Cochrane databases were searched using relevant keywords from inception until August 2025. A total of 11 studies (7 randomized controlled trials and 4 observational cohort studies) were included, comprising 3633 participants overall. The primary outcomes assessed were target lesion revascularization and target lesion failure. Meanwhile, the Secondary outcomes included stent thrombosis, all-cause mortality, myocardial infarction, major adverse cardiovascular events, survival, binary restenosis, and angiographic endpoints (acute gain, diameter stenosis, in-segment late lumen loss, in-lesion late lumen loss, and in-segment minimal lumen diameter). Interstudy heterogeneity was assessed using I ² and X ² statistics ( I ²>50% = significant heterogeneity). Interstudy heterogeneity was low for most outcomes, including all primary clinical endpoints, with moderate heterogeneity observed only for select angiographic measures (notably in-segment late lumen loss and diameter stenosis). Statistical analysis was conducted using R software and RStudio (version 4.4.2), with a P value of < 0.05 indicating statistical significance. This meta-analysis examined studies that compared paclitaxel-coated balloon (PCB) versus standard balloon [sirolimus-coated balloon (SCB)] angioplasty. Regarding primary outcomes, there were no notable variations in target lesion failure [risk ratio (RR), 1.08, 95% CI, 0.90–1.29, P = 0.36] or target lesion revascularization (RR, 1.16, 95% CI, 0.98–1.37, P = 0.08). With all aggregated estimates being nonsignificant, secondary outcomes such as stent thrombosis, all-cause mortality, myocardial infarction, major adverse cardiovascular events, and survival were similar between groups. Angiographic endpoints revealed no discernible variations in late lumen loss (in-lesion and in-segment), acute gain, or diameter stenosis. Nonetheless, the SCB group’s minimal lumen diameter was significantly smaller than that of the PCB group (MD, −0.08 mm, 95% CI, −0.14 to −0.01, P = 0.02). In treating coronary in-stent restenosis, SCB and PCBs show similar overall safety and effectiveness; lesion-specific angiographic variations indicate that customized selection may improve patient outcomes.

Abstract Aims Heart failure (HF) continues to be a major cause of morbidity and mortality worldwide, placing a significant burden on healthcare systems. Differences in the outcomes of HF hospitalizations for adults in teaching vs. non-teaching hospitals in urban settings are uncertain. We evaluated outcomes of HF hospitalizations in patients hospitalized in urban teaching vs. non-teaching hospitals in the United States. Methods and results HF hospitalizations were abstracted from the 2016 through 2022 Nationwide Readmissions Database and stratified into urban teaching vs. urban non-teaching hospital settings. Propensity-score matching was used to control for baseline differences between teaching and non-teaching hospital cohorts. Logistic regression and lognormal models were estimated to assess differences in inpatient mortality, length of stay (LOS), total costs, complications, and 30-day and 90-day all-cause readmissions. A total of 7 558 299 weighted HF hospitalizations were included in the analysis, of which 76.3% involved urban teaching hospitalizations. Compared to urban non-teaching, HF hospitalizations in urban teaching hospitals were associated with significantly higher odds of inpatient mortality (OR 1.19, 95% confidence interval [CI]: 1.16–1.22), complications including cardiogenic shock, cardiac arrest, Intra-aortic balloon pump, cardiopulmonary resuscitation, extracorporeal membrane oxygenation and mechanical ventilation use as well as more extended hospital LOS, higher total costs, palliative care consultation and readmissions rates (all P &lt; 0.001). 30-day and 90-day all-cause readmission rates were also statistically higher in teaching hospitals, though the difference was clinically non-significant. Conclusion HF hospitalizations in urban teaching hospitals were associated with higher inpatient mortality, complication rates, resource utilization, and palliative care consult rates than urban non-teaching hospitals.

Abstract Aims Coronary angiography might contain clinically relevant information, beyond its traditional role in delineating coronary artery disease. We sought to explore the role of deep learning (DL) in detecting right ventricular dysfunction from routinely acquired cine images during coronary angiography. Methods and results 3D-convolutional neural networks (CNN) were trained to identify right ventricle (RV) dysfunction from diagnostic angiography of the right coronary artery (RCA). The model’s input was two cine angiograms from LAO and RAO projections. The model’s output was normal vs. abnormal RV function. Ground truth on RV function was obtained from the nearest transthoracic echocardiogram to the coronary angiogram. Two analyses were performed to identify (i) any RV dysfunction (≥mild) and (ii) significant RV dysfunction (≥mild–moderate). A total of 10 336 coronary angiograms from 9849 patients (mean age 66, 36% women) were included. The cohort was split into training (70%), validation (15%), and testing (15%) sets. In the testing sets, the models attained an area under the ROC curve (AUC), sensitivity, and specificity of 0.82 (95% CI: 0.80–0.84), 0.75, and 0.74, for detecting any RV dysfunction, and 0.83 (95% CI: 0.80–0.86), 0.82, and 0.70 for detecting significant (≥mild–moderate) RV dysfunction. Combining an ECG-driven AI model with the angio-driven model improved the AUC values to 0.83 and 0.87 for detecting any or advanced RV dysfunction, respectively. Conclusion A novel deep learning algorithm yielded acceptable classification accuracy in detecting RV dysfunction from routine cine angiography of the RCA. The model’s performance improved further by adding ECG to its inputs.

837 Background: A recent randomized trial suggested that CR may influence ICI activity in patients with lung cancer. However, the same has not been established in GI cancers, where reports have shown mixed results with variable definitions of 'early' vs 'late' IT. We evaluated multiple approaches to assess the impact of CR on first-line ICI in GI malignancies. Methods: This retrospective study included patients from three Mayo Clinic sites (N=455). Both previously reported IT cutoffs and a new cutoff derived from ROC analysis were evaluated. Patients were categorized by the median of all ITs, the median of the first four ITs, and whether ≥20% of ITs occurred before the identified cutoff. Univariate and multivariate Cox regression (adjusting for age, MSI status, type of cancer, metastasis status, number of cycles, and receipt of chemotherapy with ICI) assessed associations with OS. KM analyses were performed to illustrate survival differences. The primary endpoint was OS. Results: When patients were categorized based on whether ≥20% of infusions occurred before 14:00 (ROC-derived cutoff), a significant association with OS was observed. On univariate analysis, early infusion timing was associated with improved survival (HR 2.30, 95% CI 1.58–3.32, p <0.001). This remained significant after multivariable adjustment (HR 2.11, 95% CI 1.41–3.16, p < 0.001). Median OS was 14.2 months in the early group vs 3.8 months in the late group (log-rank p < 0.001). Using previously defined cutoffs, categorization by the median IT of all infusions or the median of the first four infusions did not demonstrate a significant association with OS in either univariate or multivariate Cox regression analyses. Conclusions: These findings highlight the potential role of infusion timing as a chronotherapy factor in GI cancers. Given the retrospective design and heterogeneous population, prospective studies are warranted to validate this signal and clarify its clinical relevance.
