Asymptomatic aortic regurgitation (AR) has traditionally been managed conservatively until symptom onset or overt left ventricular systolic dysfunction. However, adverse myocardial remodeling—detected by myocardial strain, volumetric cardiac magnetic resonance, and fibrosis imaging—often precedes current guideline thresholds for interventions and may be irreversible. Advances in multimodal imaging now enable earlier risk stratification beyond conventional metrics. In parallel, intervention strategies are evolving, including valve repair, valve-sparing root replacement, Ross procedure, and transcatheter aortic valve replacement in selected high-risk patients. This narrative review summarizes contemporary advances in imaging and intervention for asymptomatic AR, while critically appraising current evidentiary and technical limitations that constrain earlier intervention. The review is based on a narrative synthesis of the contemporary literature, drawing from recent clinical studies, imaging advances, and guideline documents rather than a systematic evidence search.

Background Older adults undergoing percutaneous coronary intervention (PCI) face unique challenges due to complex anatomy and comorbidities. Intravascular imaging [including intravascular ultrasound (IVUS) and optical coherence tomography (OCT)] has been shown to improve PCI outcomes, but its benefits in older adults are less well established. We conducted a meta-analysis of randomized controlled trials (RCTs) to compare intravascular imaging with angiography alone to guide PCI in older adults. Methods Cochrane, PubMed, and Scopus were searched for RCTs comparing intravascular imaging (IVUS or OCT) vs. angiography alone in adults aged ≥65 years. The outcome of interest was major adverse cardiovascular events (MACE) at the longest follow-up, as defined by each trial. Subgroup analyses were performed based on intravascular imaging modality, age group, and lesion complexity. Data were pooled using random-effects models, and heterogeneity was assessed using Higgins’ I ² statistic. Results Nine RCTs ( n = 7164, intravascular imaging = 3703, angiography alone = 3461) met the inclusion criteria. Intravascular imaging significantly reduced MACE compared with angiography alone [relative risk (RR) 0.66, 95% confidence interval (CI) 0.56–0.77; P < 0.001; I ² = 0%]. IVUS demonstrated superiority over angiography alone (RR 0.55, 95% CI 0.43–0.72; P < 0.001; I ² = 0%), while OCT demonstrated only a trend toward MACE reduction (RR 0.80, 95% CI 0.62–1.02). Subgroup analyses indicated consistent benefits with intravascular imaging for adults aged ≥65 and ≥70 years, respectively, and among those with complex coronary lesions (RR 0.65, 95% CI 0.53–0.79; P < 0.001). Conclusion Intravascular imaging guidance, especially IVUS, reduces MACE in older adults undergoing PCI compared with angiography alone.

ABSTRACT We conducted a USA claims‐based cohort study in 20,705 patients with inflammatory bowel diseases (IBD) on advanced therapies to estimate the overall and comparative risk of tuberculosis between advanced therapies using inverse probability of treatment weighted Cox proportional hazards model. The incidence rate (IR, per 100,000 person‐years) of tuberculosis with TNF antagonists ( n = 9378) and non‐TNF‐targeting biologics (anti‐integrins [ n = 5877], anti‐interleukins [ n = 5450]) was similar (38 [95% CI, 8–69] vs. 33[7–59]). Adjusting for covariates, risk of tuberculosis was similar (HR, 1.16 [0.41–3.31]). In low incidence regions like USA, the incidence of tuberculosis after starting advanced therapies for IBD is very low, and comparable across advanced therapies.

INTRODUCTION: We conducted a retrospective cohort study comparing the safety of advanced therapies in patients with ulcerative colitis (UC). METHODS: Using an administrative claims database (OptumLabs Data Warehouse), we identified patients with UC who initiated treatment with tumor necrosis factor-α (TNF) antagonists, anti-integrin agents, anti-interleukin, Janus kinase inhibitors (JAK), or sphingosine-1 phosphate receptor modulators between 2016 and 2022 and had followed up for at least 1 year before and after treatment initiation. We compared the risk of serious infections, venous thromboembolism, and major adverse cardiovascular events through multinomial propensity score-based inverse probability weighting, with propensity scores estimated through generalized boosted models that accounted for disease characteristics, healthcare utilization, comorbidities, and previous and concomitant medications, and the competing risk of mortality. We calculated cause-specific hazard ratios (HR) and 95% confidence intervals for multiple treatment comparisons. RESULTS: We included 9,430 patients with UC treated with TNF antagonists (n = 4,111), anti-integrins (n = 3,165), anti-ILs (n = 1,342), JAK inhibitors (n = 701), or sphingosine-1 phosphate receptor modulators (n = 111), followed over median 27 months. After adjusting for confounding variables, anti-ILs were associated with a lower risk of serious infections compared with TNF antagonists (HR, 0.66 [95% confidence interval, 0.51–0.87]) and anti-integrins (HR, 0.75 [0.57–0.98]). JAK inhibitors were associated with a lower risk of serious infections compared with TNF antagonists (HR, 0.66 [0.46–0.94]). The incidence of venous thromboembolism (incidence rate, 1.4–2.0 per 100 py) and major adverse cardiovascular event (0.5–1.0 per 100 py) was very low, without any significant differences across agents. DISCUSSION: In a real-world cohort of patients with UC, anti-ILs and JAK inhibitors were associated with a lower risk of serious infections and may offer net benefit, especially in patients with previous TNF antagonist exposure.

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.

Abstract Objectives Emotional impairments in people with dementia can be taxing for family caregivers. However, caregivers differ in their resilience to these challenges. We previously found that, compared to healthy controls and people with Alzheimer’s disease, people with frontotemporal lobar degeneration (FTLD) have smaller physiological responses when anticipating upcoming emotional stimuli. This impairment may leave these people with FTLD unprepared for upcoming emotional stimuli because they cannot mount responses needed for appropriate behaviors, which may create stress and difficulties for caregivers. We examined (a) whether smaller preparatory physiological responses in people with dementia are associated with lower emotional well-being and physical functioning in caregivers; and (b) whether these associations are moderated by the dyads’ relationship quality. Methods A total of 158 individuals with FTLD or Alzheimer’s disease and their family caregivers participated. Preparatory physiological responses in people with dementia were quantified as decreases in cardiac interbeat intervals from baseline to an instruction period, during which they were told they would be watching an upcoming emotional film. Caregivers self-reported their emotional well-being, physical functioning, and relationship quality with the people with dementia. Results Smaller preparatory physiological responses in people with dementia were associated with lower emotional well-being (but not physical functioning) in caregivers. This association was moderated by relationship quality (i.e., weakened for caregivers in higher-quality relationships). Discussion Findings advance understanding of risk and resilience factors for negative caregiver outcomes. Positive interpersonal processes in high-quality relationships (e.g., positive appraisal of aberrant behaviors) may buffer caregivers from the impact of emotional impairments in people with dementia.

Abstract Background Lung adenocarcinoma in never-smokers is a major public health burden, especially among East Asian women. Polygenic risk scores (PRSs) are promising for risk stratification but are primarily developed in European-ancestry populations. We aimed to develop and validate single- and multi-ancestry PRSs for East Asian never-smokers to improve lung adenocarcinoma risk prediction. Methods PRSs were developed using genome-wide association study summary statistics from East Asian (8002 cases; 20 782 controls) and European (2058 cases; 5575 controls) populations. Single-ancestry models included a PRS with 25 single nucleotide variants (PRS-25), PRS clumping and thresholding (CT), and LDpred2; multi-ancestry models included LDpred2 plus European PRS-128, PRS-CSx, and clumping and thresholding, super learning, empirical Bayes (CT-SLEB). Performance was evaluated in independent East Asian data from the Female Lung Cancer Consortium and externally validated in the Nanjing Lung Cancer Cohort. We assessed predictive accuracy via area under the curve operating procedure (AUC), with 10-year and (ages 30-80 years) absolute risks estimates. Results The best multi-ancestry PRS, using East Asian and European data via CT-SLEB, outperformed the best East Asian-only (LDpred2; AUC = 0.629, 95% confidence interval [CI] = 0.618 to 0.641), achieving an AUC of 0.640 (95% CI = 0.629 to 0.653) and odds ratio of 1.71 (95% CI = 1.61 to 1.82) per standard deviation increase. Nanjing Lung Cancer Cohort validation confirmed robust performance (AUC = 0.649, 95% CI = 0.623 to 0.676). The top 20% PRS group had a 3.92-fold higher lung adenocarcinoma risk than the bottom 20%. Further, the top 5% PRS group reached a 6.69% lifetime absolute risk. Notably, this group reached the average population 10-year lung adenocarcinoma risk at age 50 years (0.42%) by age 41 years, 9 years earlier. Conclusions Multi-ancestry PRS approaches enhance lung adenocarcinoma risk stratification in East Asian never-smokers, with consistent external validation, suggesting future clinical utility.

Importance Monoclonal gammopathy of undetermined significance (MGUS) is associated with an increased risk of cardiovascular disease. Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) have demonstrated cardiorenal benefits in patients with type 2 diabetes, but their effectiveness in patients with MGUS remains unexplored. Objective To assess the effectiveness of GLP-1 RAs for primary prevention of major adverse cardiovascular and cerebrovascular events (MACCE) in patients with MGUS and diabetes. Design, Setting, and Participants This retrospective cohort study used a propensity score–matched analysis of data from the TriNetX Global Database, encompassing patients diagnosed with diabetes and MGUS between January 1, 2018, and January 13, 2023. Patients with prior heart failure (HF), ischemic heart disease, coronary revascularization, or stroke or transient ischemic attack before MGUS diagnosis were excluded. The cohort was divided into 2 groups: GLP-1 RA users and nonusers at baseline. After 1:1 propensity score matching, GLP-1 RA users and nonusers were compared up to 5 years from the MGUS diagnosis date. Data analyses were completed January 19, 2025. Exposure GLP-1 RA use within 1 year before MGUS diagnosis. Main Outcomes and Measures The primary end point was MACCE, defined as a composite of all-cause mortality, new-onset HF, acute coronary syndrome, and stroke or transient ischemic attack. Secondary end points included individual MACCE components, decompensated HF, and acute kidney injury or end-stage kidney disease. Results A total of 4871 patients with MGUS (mean [SD] age, 68.9 [10.1] years; 2366 [48.5%] male) were included (473 GLP-1 RA users and 4398 non-users). A total of 460 users were matched to 460 nonusers, with balanced characteristics (mean [SD] age, 65.0 [10.6] vs 65.1 [11.0] years; 229 [49.7%] male vs 234 [50.8%] male), including 14 patients (3.0%) vs 13 patients (2.8%) identifying as Asian, 8 (21.3%) vs 92 (20.0%) as Black or African American, 25 patients (5.4%) vs 20 patients (4.3%) as Hispanic or Latino, and 243 patients (52.8%) vs 250 patients (54.3%) as White. GLP-1 RA use was associated with a significantly lower risk of MACCE (hazard ratio [HR], 0.75; 95% CI, 0.60-0.93). Significant reductions were also observed in all-cause mortality (HR, 0.57; 95% CI, 0.37-0.87), new-onset HF (HR, 0.69; 95% CI, 0.54-0.90), decompensated HF (HR, 0.60; 95% CI, 0.43-0.84), and acute kidney injury or end-stage kidney disease (HR, 0.73; 95% CI, 0.57-0.92). Conclusions and Relevance The findings of this cohort study of GLP-1 RA use vs no use in patients with MGUS and diabetes suggest the potential of GLP-1 RA for primary prevention of MACCE. These findings warrant further investigation in prospective randomized trials.
