Abstract Background Right ventricular apical (RVA) pacing often leads to interventricular dyssynchrony and pacing-induced cardiomyopathy. Conduction system pacing (CSP), particularly Left Bundle Branch Area Pacing, provides a physiologic alternative. In Limited Resource Countries (LRCs) like Thailand, Cardiac Resynchronization Therapy (CRT) under-penetration persists due to high costs and a shortage of operators skilled in coronary venous anatomy. Objective To share the experience and provide clinical update of CSP as a sustainable, cost-effective physiological pacing strategy to improve access to advanced arrhythmia management in resource-constrained environments. Methods This review explores the implementation of minimalist protocols and CSP-based CRT. Scalability strategies include specialized training programs, device reprocessing, and the establishment of regional longitudinal registries to bridge infrastructure gaps. Results CSP-based CRT can reduce device costs by nearly 50% compared with traditional triple-lead systems. This modality effectively mitigates the hemodynamic risks of RVA pacing while bypassing the technical and financial barriers of conventional CRT. Discussion Despite its advantages, CSP adoption requires overcoming infrastructure challenges, specifically the lack of automated remote monitoring. Optimizing clinical outcomes in LRCs necessitates standardized training, robust data collection, and innovative resource management to ensure equitable access to life-saving technology.

ABSTRACT Background and Aims It remains unclear whether different factors influence 30‐ and 90‐day readmission rates. We identified predictors of 90‐day mortality in a global cohort of hospitalised patients with cirrhosis. Methods Variables associated with 30‐ and 90‐day post‐discharge readmission, liver transplantation (LT), and mortality were compared in prospectively enrolled, non‐electively hospitalised adult patients with cirrhosis. Results We enrolled 4208 patients from 125 centres across 37 countries. Alcohol‐related liver disease was the most common aetiology of cirrhosis (40%), followed by hepatitis B virus infection (21%); 47% were readmitted, 8% received liver transplantation (LT), and 23% died within 90 days post‐discharge. In multivariable analysis, country income was significantly associated with both 30‐ and 90‐day readmission rates, the receipt of LT, and mortality within 30 and 90 days post‐discharge (all p ‐values < 0.001). Independent predictors of higher rates of 30‐ and 90‐day readmissions, respectively, were disease severity ( p < 0.001, p = 0.003), prior ascites ( p = 0.025, p = 0.016), prior hospitalisation ( p < 0.001), hyponatremia ( p < 0.001, p = 0.008), and in‐hospital vasopressor use ( p = 0.002, p = 0.011). Prior variceal bleeding independently predicted higher 90‐day readmission rates, whereas age, disease severity, mechanical ventilation, and in‐hospital vasopressor use (all, p < 0.001) increased odds of 30‐ and 90‐day post‐discharge death. Additionally, admission ( p = 0.011) and nosocomial ( p = 0.022) infections increased the odds of 90‐day post‐discharge death. Conclusion In a global cohort of hospitalised patients with cirrhosis, patients in high‐income countries exhibited the highest rates of 30‐ and 90‐day readmission, alongside lower mortality rates and a higher incidence of LT. Variables that predict 30‐day readmission also predicted 90‐day readmission. Understanding these disparities is essential for achieving health equity.

Background: Increased arterial stiffness, a marker of cardiovascular disease (CVD), is prevalent among African American (AA) adults and contributes to persistent CVD disparities. The Cardio-Ankle Vascular Index (CAVI) is a validated measure of arterial stiffness and predictor of adverse CVD outcomes. However, its relationship with the novel American Heart Association’s Life’s Essential 8 (LE8) cardiovascular health (CVH) construct has not been examined among AAs. Hypothesis: We hypothesized that increased arterial stiffness would be associated with lower CVH among AA adults. Methods: We analyzed baseline data from AA adults in the Techquity by FAITH! Trial, a 2-arm cluster randomized controlled trial conducted across 18 AA churches in Rochester and Minneapolis–St. Paul, Minnesota. Eligible participants (age ≥18 years with suboptimal diet or physical activity [PA]) completed validated electronic surveys (e.g., PA patterns) and clinical assessments (e.g., blood pressure [BP], lipids). CAVI was summarized as mean and categorized as normal (<8), borderline (8 to <9), or abnormal (≥9). CVH was assessed using the LE8 score (range 0-100 points) and categorized as low (<50), moderate (50-79), or high (≥80). Associations between CAVI and LE8 were assessed using multivariable linear regression adjusted for age, sex, and income (continuous) and Fisher’s exact test (categorical). LE8 components were compared across CAVI categories using Kruskal–Wallis tests. Results: Among 140 participants (mean age 53.0 years [SD 14.6]; 68% female), the mean LE8 score was 62.7 (SD 14.0). Nicotine exposure LE8 score was the highest (84.6 [SD 26.6]) and diet was the lowest (40.7 [SD 13.7]). Mean CAVI was 7.9 (SD 1.5), with 50% of participants classified as normal, 22% borderline, and 28% abnormal. No association between continuous CAVI and LE8 scores was observed after adjustment (unadjusted R 2 = 3.5%). All participants with high LE8 had normal CAVI, while abnormal CAVI was more prevalent among those with low (40%) and moderate (30%) LE8 scores (p<0.001). LE8 scores differed across CAVI categories for BP (median 50 in normal CAVI vs 30 in borderline/abnormal CAVI; p=0.003) and glucose LE8 scores (median 100 vs 60; p=0.014). Conclusions: Greater arterial stiffness was associated with lower CVH categories, with notable component-level differences in BP and glucose. Although not independently associated with overall LE8, integrating CAVI and LE8 categories may improve CVD risk stratification among AAs.

Importance Currently, there are no standardized outcome domains or measures in clinical trials for facial aging. Heterogeneity in outcome domains and measurement instruments across clinical trials creates difficulty in directly comparing interventions, determining superior therapies, and developing high-quality meta-analyses. Objective To develop a core outcome set (COS) of essential domains to be reported in clinical trials evaluating the efficacy of interventions for facial aging. Evidence Review PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL were searched from September 2005 to September 2015. An updated search of the same databases was performed from September 2015 to February 2026. Studies were included if (1) they were randomized clinical trial or controlled clinical trial in design, (2) they assessed the efficacy or safety of an intervention for facial aging, (3) they were published in English, and (4) they involved human participants. Complementary sources, including patient interviews, were used to capture further relevant outcomes. Two rounds of Delphi surveys, followed by consensus meetings, were used to identify outcome domains considered most important by both patient and physician stakeholders. Findings The final COS consists of 6 outcome domains: (1) overall convenience of treatment; (2) time to return to normal work and social activity; (3) overall assessment of focused area of treatment (at the point in time when treatment is expected to provide peak benefit); (4) duration of treatment effect; (5) severity of persistent local or systemic adverse events, including pigmentary change, skin texture change, delayed healing, scarring, and serious adverse events; and (6) patient satisfaction with treatment. Conclusions and Relevance The 6 outcome domains identified through a Delphi consensus are recommended for reporting in future facial aging trials to ensure that outcomes that matter most to patients and clinicians are measured and that results are comparable across interventions.

Abstract Newer approaches to control alloreactivity may produce similar transplant outcomes using HLA-mismatched donors vs HLA-matched unrelated donors (MUD). However, prospective comparisons are lacking. BMT CTN 1702 used a donor search prognosis score to assign patients to an 8/8 HLA MUD or the center’s preference of haploidentical related donors (HAPLO), mismatched unrelated donors (MMUD), or umbilical cord blood (UCB). Outcomes of MUD were compared to HAPLO, MMUD, and UCB transplantation after adjusting for covariates. Patients (n = 1179 [93% adults]) underwent transplantation with MUD (n = 772), HAPLO (n = 254), MMUD (n = 112), and UCB (n = 41) at a median of 3.7, 3.4, 3.9, and 3.8 months from enrollment. Posttransplant cyclophosphamide (PTCy) was used in 23.9%, 83.9%, 65.2%, and 0% of MUD, HAPLO, MMUD, and UCB. In multivariate analyses, compared to MUD, survival was lower for UCB (hazard ratio [HR], 2.65; P&lt; .001) but not statistically different for HAPLO and MMUD (HRs, 1.08 and 1.18, respectively). Relapse risk was not significantly different by donor, but treatment-related mortality (HR, 3.31; P&lt; .001) and disease-free survival (HR, 1.99; P = .002) were inferior for UCB but not different for HAPLO and MMUD than MUD. In patients who received PTCy, HAPLO and MMUD were associated with increased grade 3 or 4 acute graft-versus-host disease (GVHD; HR, 2.39 [P = .017] and 2.53 [P = .038], respectively) and chronic GVHD (HR, 1.71 for both; P = .028 and .080) than MUD, but other outcomes were not different. HAPLO or MMUD may be used to expedite transplantation when finding MUD is unlikely. This study was registered at www.clinicaltrials.gov as NCT03904134.

INTRODUCTION: Nosocomial infections (NIs) in cirrhosis are associated with high mortality but could be preventable. Logistic regression (LR) models have failed to identify high-risk patients. We aimed to develop machine learning (ML) models to predict NI. METHODS: The CLEARED consortium consists of prospectively enrolled cirrhosis inpatients from >120 centers. Using day-of-admission clinical data, 3 ML approaches (random forest [RF], extreme gradient boosting, and neural networks [NNs]) were used to predict NI. Data were split 80:20 for training and testing stratified by the outcome. Models were compared using area under the receiver operating characteristic curve (AUC). RESULTS: In total, 8,263 patients (55.90 ± 13.34 years; 64.1% men) from 127 centers in 37 countries were included. NI developed in 869 (10.5%), a median of 6 (4–11) days of postadmission. Major NIs were respiratory (29.6%) and urinary tract infection (15.7%), and spontaneous bacterial peritonitis (13.5%). NIs occurred more frequently in patients from low/low-middle income countries and those with severe liver disease, alcohol etiology, and admission infections. NIs were associated with inpatient mortality (31.9% vs 8.1%, P < 0.001) and liver transplantation (4.8% vs 1.9%, P < 0.001). Although the RF model (AUC 0.69) showed good calibration (Brier score 0.09), outperforming extreme gradient boosting, neural network, and LR models (AUC 0.66 for all; LR comparison P = 0.043), no model achieved AUC ≥0.80 for clinical utility. At 10% predicted probability threshold, the RF model demonstrated only 75.4% sensitivity, 52.9% specificity, and 15.9% positive predictive value (PPV). DISCUSSION: NIs cannot be accurately predicted from day-of-admission data using ML models, even in a large, prospective, global cirrhosis cohort. Every hospitalized patient with cirrhosis should receive protocolized infection control measures.

Abstract Background: DS-8201a is a HER2-targeting antibody drug conjugate with a topoisomerase 1 (topo1) inhibitor payload. Preclinical evidence suggests that inhibiting PARP can potentiate topo1 inhibitor-induced DNA damage and cytotoxicity. However, the clinical activity of combined topo1-inhibiting chemotherapy and PARP inhibition has been limited by toxicity. We hypothesized that targeted delivery of a topo1 inhibitor via DS-8201a may reduce systemic toxicity, while maintaining synergistic cytotoxic activity in combination with olaparib (PARPi). DS-8201a + olaparib was evaluated in the ongoing CTEP #10355 trial (NCT04585958). Results from Dose Escalation are presented. Methods: Accrual was limited to pts ≥18 years old with advanced or recurrent solid tumors expressing HER2, defined as HER2 IHC ≥1+ or ERBB2 amplification by NGS or ISH (local testing allowed). DS-8201a was given Q3W across all dose escalation regimens. Olaparib dosing in continuous (Module 1 D1-21) and intermittent schedules (Module 2 D8-14; Module 3 D3-9) were explored. A 3+3 dose escalation design was followed in Mod 1 & 2 and up to 6 pts in a safety cohort were planned for Mod 3. Primary endpoints included safety as graded by CTCAE v5 and determination of an RP2D. Results: As of Oct 26, 2025, 30 pts were enrolled and 28 pts were treated. 12 pts had uterine and 16 pts had ovarian cancer; mean age was 61.6 years, median number of prior therapies was 4 (range 1-10). HER2 expression by local testing was: 4 pts IHC 1+, 17 pts IHC 2+, 6 pts IHC 3+, 1 pt ERBB2 amplification (IHC not reported). 9/10 pts enrolled in Mod 1 (continuous olaparib) were DLT-evaluable: 1/7 pts at DL1 (DS-8201a 4.4mg/kg IV Q3W + olaparib 100mg BID D1-21) and 3/3 pts at DL2 (DS-8201a 5.4mg/kg IV Q3W + olaparib 100mg BID D1-21) experienced DLTs (G4 neutropenia, febrile neutropenia, WBC decrease, colitis), halting further Mod 1 enrollment. 12/16 pts enrolled to Mod 2 (intermittent olaparib) were DLT-evaluable and only 1 pt at the highest dose level (DL3, DS-8201a 5.4mg/kg IV Q3W + olaparib 300mg BID D8-14) experienced a DLT (G3 colitis). Hematologic TRAEs were markedly attenuated in Mod 2 compared to Mod 1: 12% vs 30% G3 and 19% vs 50% G4 neutropenia; 25% vs 70% G3 anemia; 6% vs 20% G3 and 0% vs 20% G4 thrombocytopenia. 2/2 DLT-evaluable pts in Mod 3 (intermittent olaparib; DS-8201a 5.4mg/kg IV Q3W + olaparib 300mg BID D3-9) experienced DLTs (G3 diarrhea, G3 nausea & vomiting, G4 neutropenia), halting further Mod 3 enrollment. The Mod 2 DL3 regimen of DS-8201a 5.4mg/kg IV Q3W + olaparib 300mg BID D8-14 was declared the RP2D and is under further investigation in an ongoing Dose Expansion cohort enrolling HER2 IHC 1+ platinum resistant ovarian cancer. Objective responses were observed across all modules and dose levels. Conclusions: In pts with HER2-expressing advanced solid tumors, DS-8201a in combination with intermittently-dosed olaparib was tolerable. DS-8201a 5.4mg/kg IV Q3W + olaparib 300mg BID D8-14 was selected as the RP2D for further evaluation in Dose Expansion. Additional endpoints of clinical activity will be presented.

Background/Aims: Infections with drug-resistant organisms (DROs) are associated with poor outcomes in cirrhosis. Rifaximin, widely used for hepatic encephalopathy (HE), could promote cross-resistance, but data regarding clinical impact are conflicting. Aim: Determine predictors of DROs in a global cirrhosis inpatient cohort focusing on preadmission rifaximin use.Methods: From the global CLEARED consortium, we focused on cirrhosis inpatients with infections on/during admission. Clinical/demographic/medication, especially rifaximin details were recorded. The primary outcome was DRO development. Multivariable regression for DRO including clinical, medications, and country income was performed.Results: 2,949 infected inpatients (55.3 years, 62.9% male) were included. 12.2% of all and 24.4% of culture-positive infections developed DROs; these patients had higher HE (39 vs. 31%, <i>P</i>=0.003), hepatorenal syndrome (25 vs. 19%, <i>P</i>=0.006), lactulose (55 vs. 47%, <i>P</i>=0.008) and rifaximin use (34 vs. 27%, <i>P</i>=0.006) on crude comparisons but country-income distributions were similar. 29.7% were on pre-admission rifaximin, mostly HE-related; they had more advanced cirrhosis and from low/low-middle-income countries. Daptomycin was used in 1.5%, linked with DROs (5.0 vs. 1.0%, <i>P</i><0.0001) without a difference in rifaximin use (1.4 vs.1.7%, <i>P</i>=0.61). On adjusted analysis, MELD-Na (1.03, 95% CI 1.02–1.04, <i>P</i><0.001) increased, whereas male sex (0.73, 95% CI 0.58–0.92, <i>P</i>=0.008) and hepatitis-B (0.65, 95% CI 0.45–0.92, <i>P</i>=0.020) decreased DRO. Rifaximin was not associated with DROs overall (OR 1.07, 95% CI 0.80–1.43, <i>P</i>=0.65) or within income strata (high: 1.07, 95% CI 0.59–1.92, <i>P</i>=0.82, upper-middle: 1.18, 95% CI 0.74–1.85, <i>P</i>=0.49, low/low-middle: 1.04, 95% CI 0.60–1.81, <i>P</i>=0.90) despite sensitivity analyses.Conclusions: In this large global cohort of hospitalized patients with cirrhosis and infections, 12% developed infections involving DROs. 30% had pre-admission rifaximin use which was not linked with daptomycin use or with DRO development on adjusted analysis overall or across country income groups.

Abstract Spontaneous coronary artery dissection is an unusual, but increasingly recognized, cause of acute coronary syndrome. It is a potentially fatal disorder that predominantly (&gt;90% of cases) affects women, who are about 20 years younger (age 45–52 years) than those presenting with an acute coronary syndrome due to atherosclerotic coronary artery disease, and is the commonest cause of myocardial infarction associated with pregnancy. With the advent of improved coronary artery imaging modalities, including invasive coronary angiography, intravascular ultrasonography (IVUS), and optical coherence tomography (OCT), spontaneous coronary artery dissection is being increasingly diagnosed. It is typically due to a spontaneous bleed in the tunica media of an epicardial coronary artery, with or without an intimal tear, that results in an intramural haematoma; the latter, in turn causing a separation or dissection of the lamellae formed by the layers of smooth muscle cells of the tunica media, which can propagate longitudinally. Although coronary artery dissection can be due to atherosclerotic disease that may, in fact, present spontaneously, or to trauma, or guidewire-induced intimal injury, the understanding that the entity now known as spontaneous coronary artery dissection is an idiopathic disorder that is not associated with atherosclerosis or trauma, and is not iatrogenic, is one that has emerged only relatively recently (last 10–15 years). This raises the question, what is the provenance of spontaneous coronary artery dissection as it is now defined and understood? Here, this issue is addressed by a detailed consideration of the medical literature from 1800.
