Background The American Heart Association's Life's Essential 8 (LE8) are 8 risk factors for cardiovascular disease, with poor attainment across all racial, ethnic, and socioeconomic groups. Attainment is lowest among Americans of low socioeconomic status (SES). Evidence suggests the association of SES with LE8 may vary by race and ethnicity. Methods and Results The association of 4 SES categories (education, income‐to‐poverty line ratio, employment, insurance) with LE8 was computed in age‐adjusted linear regression models, with an interaction term for race and ethnicity, using National Health and Nutrition Examination Survey data, years 2011 to 2018. The sample (n=13 529) had a median age of 48 years (51% female) with weighting to be representative of the US population. The magnitude of positive association of college education (relative to ≤high school) with LE8 was greater among non‐Hispanic White Americans (NHWA) compared with non‐Hispanic Black Americans, Hispanic Americans, and non‐Hispanic Asian Americans (all interactions P <0.001). NHWA had a greater magnitude of positive association of income‐to‐poverty line ratio with LE8, compared with non‐Hispanic Black Americans, Hispanic Americans, and non‐Hispanic Asian Americans (all interactions P <0.001). NHWA with Medicaid compared with private insurance had a greater magnitude of negative association with LE8 compared with non‐Hispanic Black Americans, non‐Hispanic Asian Americans, or Hispanic Americans (all interactions P <0.01). NHWA unemployed due to disability or health condition (compared with employed) had a greater magnitude of negative association with LE8 than non‐Hispanic Black Americans, non‐Hispanic Asian Americans, or Hispanic Americans (all interactions P <0.05). Conclusions The magnitude of association of SES with LE8 is greatest among NHWA. More research is needed on SES's role in LE8 attainment in minority group populations.

AbstractBackgroundGastroparesis is defined by delayed gastric emptying (GE) without obstruction. Studies suggest targeting heme oxygenase‐1 (HO1) may ameliorate diabetic gastroparesis. Upregulation of HO1 expression via interleukin‐10 (IL‐10) in the gastric muscularis propria is associated with reversal of delayed GE in diabetic NOD mice. IL‐10 activates the M2 cytoprotective phenotype of macrophages and induces expression of HO1 protein. Here, we assess delivery of HO1 by recombinant adeno‐associated viruses (AAVs) in diabetic mice with delayed GE.MethodsC57BL6 diabetic delayed GE mice were injected with 1 × 1012 vg scAAV9‐cre, scAAV9‐GFP, or scAAV9‐HO1 particles. Changes to GE were assessed weekly utilizing our [13C]‐octanoic acid breath test. Stomach tissue was collected to assess the effect of scAAV9 treatment on Kit, NOS1, and HO1 expression.Key ResultsDelayed GE returned to normal within 2 weeks of treatment in 7/12 mice receiving scAAV9‐cre and in 4/5 mice that received the scAAV9‐GFP, whereas mice that received scAAV9‐HO1 did not respond in the same manner and had GE that took significantly longer to return to normal (6/7 mice at 4–6 weeks). Kit, NOS1, and HO1 protein expression in scAAV9‐GFP‐treated mice with normal GE were not significantly different compared with diabetic mice with delayed GE.Conclusions and InferencesInjection of scAAV9 into diabetic C57BL6 mice produced a biological response that resulted in acceleration of GE independently of the cargo delivered by the AAV9 vector. Further research is needed to determine whether use of AAV mediated gene transduction in the gastric muscularis propria is beneficial and warranted.

BACKGROUND: Global collaboration in cardio-oncology is needed to understand the prevalence of cancer therapy-related cardiovascular toxicity in different risk groups, practice settings, and geographic locations. There are limited data on the socioeconomic and racial/ethnic disparities that may impact access to care and outcomes. To address these gaps, we established the Global Cardio-Oncology Registry, a multinational, multicenter prospective registry. METHODS: We assembled cardiologists and oncologists from academic and community settings to collaborate in the first Global Cardio-Oncology Registry. Subsequently, a survey for site resources, demographics, and intention to participate was conducted. We designed an online data platform to facilitate this global initiative. RESULTS: A total of 119 sites responded to an online questionnaire on their practices and main goals of the registry: 49 US sites from 23 states and 70 international sites from 5 continents indicated a willingness to participate in the Global Cardio-Oncology Registry. Sites were more commonly led by cardiologists (85/119; 72%) and were more often university/teaching (81/119; 68%) than community based (38/119; 32%). The average number of cardio-oncology patients treated per month was 80 per site. The top 3 Global Cardio-Oncology Registry priorities in cardio-oncology care were breast cancer, hematologic malignancies, and patients treated with immune checkpoint inhibitors. Executive and scientific committees and specific committees were established. A pilot phase for breast cancer using Research Electronic Data Capture Cloud platform recently started patient enrollment. CONCLUSIONS: We present the structure for a global collaboration. Information derived from the Global Cardio-Oncology Registry will help understand the risk factors impacting cancer therapy-related cardiovascular toxicity in different geographic locations and therefore contribute to reduce access gaps in cardio-oncology care. Risk calculators will be prospectively derived and validated.

Abstract Dynamic measures of resilience—the ability to resist and recover from a challenge—may be informative of the rate of aging before overt manifestations such as chronic disease, disability, and frailty. From this perspective mid-life resilience may predict longevity and late-life health. To test this hypothesis, we developed simple, reproducible, clinically relevant challenges, and outcome measures of physical resilience that revealed differences between and within age groups of genetically heterogeneous mice, and then examined associations between mid-life resilience and both lifespan and late-life measures of physiological function. We demonstrate that time to recovery from isoflurane anesthesia and weight change following a regimen of chemotherapy significantly differed among young, middle-aged, and older mice, and were more variable in older mice. Females that recovered faster than the median time from anesthesia (more resilient) at 12 months of age lived 8% longer than their counterparts, while more resilient males in mid-life exhibited better cardiac (fractional shortening and left ventricular volumes) and metabolic (glucose tolerance) function at 24 months of age. Moreover, female mice with less than the median weight loss at Day 3 of the cisplatin challenge lived 8% longer than those that lost more weight. In contrast, females who had more weight loss between Days 15 and 20 were relatively protected against early death. These data suggest that measures of physical resilience in mid-life may provide information about individual differences in aging, lifespan, and key parameters of late-life health.

AbstractObjectiveInternal nasal valve dysfunction is a prevalent cause of nasal obstruction. This systematic review, along with a Meta‐analysis, evaluated the efficacy of temperature‐controlled radiofrequency device (RFD) treatment in alleviating nasal obstruction by rectifying nasal valve collapse.Data SourcesA comprehensive review of studies retrieved from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases (up to December 2022) was conducted.Review MethodsWe included studies that evaluated the quality of life and nasal obstruction scores before and after RFD treatment. In addition, sham‐controlled studies were analyzed.ResultsIn total, 451 patients across 8 studies were included in the analysis. Patients who underwent RFD treatment reported a significantly enhanced quality of life 24 months after treatment compared to pretreatment scores. The rates of clinically improved states and positive responses regarding quality of life after treatment were 82% and 91%, respectively. Moreover, the disease‐specific quality of life, as assessed by the Nasal Obstruction Symptom Evaluation score, significantly improved.ConclusionRFD may help improve nasal obstruction symptoms. Further randomized clinical studies on larger cohorts are essential to substantiate its efficacy in enhancing nasal valve function.

AbstractBackgroundBladder cancer is a significant malignancy in humans and canines, with high death rates and devastating clinical symptoms. Despite significant advances in therapeutic management over the years, only a small fraction of bladder cancer patients respond to immunotherapies as a second line of treatment. Since immunotherapies act on various cellular and molecular targets in the bladder cancer tumour microenvironment (TME), a greater understanding of the various types of immune cells, immune checkpoint molecules and cytokines involved in antitumour immunity will help to improve the success rate of current and novel immunotherapies, therefore enhancing the patients quality of life. Accumulating evidence shows fundamental similarities between human and canine muscle‐invasive bladder cancer (MIBC) in their clinical, histological and molecular features.AimThis review focuses on comparative aspects of MIBC in both species, highlighting the role that canines can play as a model for studying MIBC. Additionally, we discuss the various types of immune cells within bladder cancer TME that can influence the prognosis and response to immunotherapy and chemotherapy in both species.ConclusionIt remains challenging to recapitulate the heterogeneity and complexity of the bladder cancer tumour microenvironment using in vivo and in vitro models, such as zebrafish and 3D organoids models. Optimization of these techniques to create a more representative translational model has been facilitated through in vitro immune‐oncology cocultures, which are considered promising tools to help select the ideal individualized treatment options and predict disease prognosis.

Rare familial spontaneous coronary artery dissection (SCAD) kindreds implicate genetic disease predisposition and provide a unique opportunity for candidate gene discovery. Whole-genome sequencing was performed in fifteen probands with non-syndromic SCAD who had a relative with SCAD, eight of whom had a second relative with extra-coronary arteriopathy. Co-segregating variants and associated genes were prioritized by quantitative variant, gene, and disease-level metrics. Curated public databases were queried for functional relationships among encoded proteins. Fifty-four heterozygous coding variants in thirteen families co-segregated with disease and fulfilled primary filters of rarity, gene variation constraint, and predicted-deleterious protein effect. Secondary filters yielded 11 prioritized candidate genes in 12 families, with high arterial tissue expression (n = 7), high-confidence protein-level interactions with genes associated with SCAD previously (n = 10), and/or previous associations with connective tissue disorders and aortopathies (n = 3) or other vascular phenotypes in mice or humans (n = 11). High-confidence associations were identified among 10 familial SCAD candidate-gene-encoded proteins. A collagen-encoding gene was identified in five families, two with distinct variants in COL4A2. Familial SCAD is genetically heterogeneous, yet perturbations of extracellular matrix, cytoskeletal, and cell–cell adhesion proteins implicate common disease-susceptibility pathways. Incomplete penetrance and variable expression suggest genetic or environmental modifiers.

Abstract Tumor-related epilepsy (TRE) is a frequent and major consequence of brain tumors. Management of TRE is required throughout the course of disease and a deep understanding of diagnosis and treatment is key to improving quality of life. Gross total resection is favored from both an oncologic and epilepsy perspective. Shared mechanisms of tumor growth and epilepsy exist, and emerging data will provide better targeted therapy options. Initial treatment with antiseizure medications (ASM) in conjunction with surgery and/or chemoradiotherapy is typical. The first choice of ASM is critical to optimize seizure control and tolerability considering the effects of the tumor itself. These agents carry a potential for drug–drug interactions and therefore knowledge of mechanisms of action and interactions is needed. A review of adverse effects is necessary to guide ASM adjustments and decision-making. This review highlights the essential aspects of diagnosis and treatment of TRE with ASMs, surgery, chemotherapy, and radiotherapy while indicating areas of uncertainty. Future studies should consider the use of a standardized method of seizure tracking and incorporating seizure outcomes as a primary endpoint of tumor treatment trials.
