RESUMEN

The objective of this study was to determine whether exposure to structural racism-related state laws is associated with cardiovascular health among a racially and ethnically diverse sample of US adults. Data were from the Database of Structural Racism-Related State Laws and the Behavioral Risk Factor Surveillance System (BRFSS). The sample included 958,019 BRFSS 2011 and 2013 respondents aged 18+ from all 50 US states. The exposure was a summary index of 22 state laws related to the criminal legal system, economics and labor, education, healthcare, housing, immigration, and political participation. The outcome was the American Heart Association's Life's Simple 7 (LS7), a summary index of seven cardiovascular health indicators. Linear regression models included fixed effects for year and state to control for time trends and unmeasured time-invariant state-level contextual factors. In the full sample, a one standard deviation increase in the structural racism state legal index was associated with a 0.06-unit decrease in the LS7 (b=-0.06; 95% CI:-0.09, 0.02; p=0.001), controlling for individual- and state-level covariates. Contrary to expectations, stratified models revealed no statistically significant differences by race and ethnicity in the association between the structural racism state legal index and the LS7.

RESUMEN

Importance: Racial disparities in cardiovascular health, including sudden cardiac death (SCD), exist among both the general and athlete populations. Among competitive athletes, disparities in health outcomes potentially influenced by social determinants of health (SDOH) and structural racism remain inadequately understood. This narrative review centers on race in sports cardiology, addressing racial disparities in SCD risk, false-positive cardiac screening rates among athletes, and the prevalence of left ventricular hypertrophy, and encourages a reexamination of race-based practices in sports cardiology, such as the interpretation of screening 12-lead electrocardiogram findings. Observations: Drawing from an array of sources, including epidemiological data and broader medical literature, this narrative review discusses racial disparities in sports cardiology and calls for a paradigm shift in approach that encompasses 3 key principles: race-conscious awareness, clinical inclusivity, and research-driven refinement of clinical practice. These proposed principles call for a shift away from race-based assumptions towards individualized, health-focused care in sports cardiology. This shift would include fostering awareness of sociopolitical constructs, diversifying the medical team workforce, and conducting diverse, evidence-based research to better understand disparities and address inequities in sports cardiology care. Conclusions and Relevance: In sports cardiology, inadequate consideration of the impact of structural racism and SDOH on racial disparities in health outcomes among athletes has resulted in potential biases in current normative standards and in the clinical approach to the cardiovascular care of athletes. An evidence-based approach to successfully address disparities requires pivoting from outdated race-based practices to a race-conscious framework to better understand and improve health care outcomes for diverse athletic populations.

RESUMEN

We sought to evaluate the acceptability and feasibility of a culturally tailored food box intervention for improving blood pressure (BP), food security and Body Mass Index (BMI) among Chickasaw Nation adults with uncontrolled hypertension. As part of the Chickasaw Healthy Eating Environments Research Study (CHEERS), we administered a group randomized pilot study in four tribal communities (two intervention, two control). Participants in the intervention communities received six heart-healthy food boxes, culturally tailored to traditional Chickasaw diet and current food context. Outcomes were measured over 6 months. We enrolled 262 participants, and 204 with complete data on key variables were included in the analysis. The food boxes were very popular, and we achieved high retention for follow-up data collection. Intervention community participants had 2.6 mmHg lower mean systolic BP and improved diet quality and BMI compared with control participants, although, as expected for a pilot study, the differences were not statistically significant. The culturally tailored diet intervention and randomized trial study design were acceptable and feasible for Chickasaw Nation adults with uncontrolled hypertension. Our findings support the value of tribal-food bank partnerships as a potential approach for reducing food insecurity and hypertension-related disparities in Native American communities.

RESUMEN

BACKGROUND: Black women with peripartum cardiomyopathy (PPCM) have a higher prevalence of hypertensive disorders of pregnancy (HDP) and worse clinical outcomes compared with non-Black women. We examined the impact of HDP on myocardial recovery in Black women with PPCM. METHODS: A total of 100 women were enrolled into the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study. Left ventricular ejection fraction (LVEF) was assessed by echocardiography at entry, 6, and 12-months post-partum (PP). Women were followed for 12 months postpartum and outcomes including persistent cardiomyopathy (LVEF≤35%), left ventricular assist device, (LVAD), cardiac transplantation, or death were examined in subsets based on race and the presence of HDP. RESULTS: Black women with HDP were more likely to present earlier compared to Black women without HDP (days PP HDP: 34±21 vs 54±27 days, P=0.03). There was no difference in LVEF at study entry for Black women based on HDP, but better recovery with HDP at 6 (HDP:52±11% vs no HDP: 40±14%, P=0.03) and 12-months (HDP:53±10% vs no HDP:40±16%, P=0.02). At 12-months, Black women overall had a lower LVEF than non-Black women (P<0.001), driven by less recovery in Black women without HDP compared to non-Black women (P<0.001). In contrast, Black women with HDP had a similar LVEF at 12 months compared to non-Black women (P=0.56). CONCLUSIONS: In women with PPCM, poorer outcomes evident in Black women were driven by women without a history of HDP. In Black women, a history of HDP was associated with earlier presentation and recovery which was comparable to non-Black women.

RESUMEN

Notch proteins are single pass transmembrane receptors that are activated by proteolytic cleavage, allowing their cytosolic domains to function as transcription factors in the nucleus. Upon binding, Delta/Serrate/LAG-2 (DSL) ligands activate Notch by exerting a "pulling" force across the intercellular ligand/receptor bridge. This pulling force is generated by Epsin-mediated endocytosis of ligand into the signal-sending cells, and results in cleavage of the force-sensing Negative Regulatory Region (NRR) of the receptor by an ADAM10 protease [Kuzbanian (Kuz) in Drosophila ]. Here, we have used chimeric Notch and DSL proteins to screen for other domains that can substitute for the NRR in the developing Drosophila wing. While many of the tested domains are either refractory to cleavage or constitutively cleaved, we identify several that mediate Notch activation in response to ligand. These NRR analogues derive from widely divergent source proteins and have strikingly different predicted structures. Yet, almost all depend on force exerted by Epsin-mediated ligand endocytosis and cleavage catalyzed by Kuz. We posit that the sequence space of protein domains that can serve as force-sensing proteolytic switches in Notch activation is unexpectedly large, a conclusion that has implications for the mechanism of target recognition by Kuz/ADAM10 proteases and is consistent with a more general role for force dependent ADAM10 proteolysis in other cell contact-dependent signaling mechanisms. Our results also validate the screen for increasing the repertoire of proteolytic switches available for synthetic Notch (synNotch) therapies and tissue engineering.

RESUMEN

PURPOSE: We aimed to describe RAS mutations in gynecologic cancers as they relate to clinicopathologic and genomic features, survival, and therapeutic implications. EXPERIMENTAL DESIGN: Gynecologic cancers with available somatic molecular profiling data at our institution between February 2010 and August 2022 were included and grouped by RAS mutation status. Overall survival was estimated by the Kaplan-Meier method, and multivariable analysis was performed using the Cox proportional hazard model. RESULTS: Of 3,328 gynecologic cancers, 523 (15.7%) showed any RAS mutation. Patients with RAS-mutated tumors were younger (57 vs. 60 years nonmutated), had a higher prevalence of endometriosis (27.3% vs. 16.9%), and lower grades (grade 1/2, 43.2% vs. 8.1%, all P < 0.0001). The highest prevalence of KRAS mutation was in mesonephric-like endometrial (100%, n = 9/9), mesonephric-like ovarian (83.3%, n = 5/6), mucinous ovarian (60.4%), and low-grade serous ovarian (44.4%) cancers. After adjustment for age, cancer type, and grade, RAS mutation was associated with worse overall survival [hazard ratio (HR) = 1.3; P = 0.001]. Specific mutations were in KRAS (13.5%), NRAS (2.0%), and HRAS (0.51%), most commonly KRAS G12D (28.4%) and G12V (26.1%). Common co-mutations were PIK3CA (30.9%), PTEN (28.8%), ARID1A (28.0%), and TP53 (27.9%), of which 64.7% were actionable. RAS + MAPK pathway-targeted therapies were administered to 62 patients with RAS-mutated cancers. While overall survival was significantly higher with therapy [8.4 years [(95% confidence interval (CI), 5.5-12.0) vs. 5.5 years (95% CI, 4.6-6.6); HR = 0.67; P = 0.031], this effect did not persist in multivariable analysis. CONCLUSIONS: RAS mutations in gynecologic cancers have a distinct histopathologic distribution and may impact overall survival. PIK3CA, PTEN, and ARID1A are potentially actionable co-alterations. RAS pathway-targeted therapy should be considered.

RESUMEN

BACKGROUND: Dietary interventions are used for the treatment of hypertension. We evaluated the cost-efficacy of delivering boxes of healthy, culturally tailored foods and checks that can only be spent on produce in a Native American population. METHODS: We conducted a group randomized controlled trial from 2018 to 2020 with N = 2 treatment counties and N = 2 control counties and a total of N = 160 Native American adults with baseline stage 1 or stage 2 hypertension. Participants in the intervention group received monthly boxes of food that adheres to the Dietary Approaches to Stop Hypertension diet as well as checks that could only be spent on produce for 6 months. We measured blood pressure and quality of life at baseline and at a 6-month follow-up in both intervention and control groups. We used ordered logistic regression to estimate the effect of treatment on probability of blood pressure improvements. We then conducted a cost-efficacy analysis. RESULTS: We found that treatment was effective in reducing blood pressure in women with stage 1 hypertension at baseline. Based on this finding, we also estimate that this intervention satisfies normative cost-effectiveness thresholds, even when lifetime treatment is needed to preserve the impact, so long as treatment is only continued in those who respond to treatment. CONCLUSIONS: Direct delivery of healthy foods and checks that can only be spent on produce are a potentially cost-effective intervention for the management of hypertension among Native American women with stage 1 hypertension. Further research is needed to understand why we found an impact only for this group.

RESUMEN

Previous studies have shown the clinical benefit of rechallenging the RAF pathway in melanoma patients previously treated with BRAF inhibitors. 44 patients with multiple tumors harboring RAF alterations were rechallenged with a second RAF inhibitor, either as monotherapy or in combination with other therapies, after prior therapy with a first RAF inhibitor. This retrospective observational study results showed that rechallenging with RAFi(s) led to an overall response rate of 18.1% [PR in thyroid (1 anaplastic; 3 papillary), 1 ovarian, 2 melanoma, 1 cholangiocarcinoma, and 1 anaplastic astrocytoma]. The clinical benefit rate was 54.5%; more than 30% of patients had durable responses with PR and SD lasting > 6 months. The median progression-free survival on therapy with second RAF inhibitor in the rechallenge setting either as monotherapy or combination was shorter at 2.7 months (0.9-30.1 m) compared to 8.6 months (6.5-11.5 m) with RAF-1i. However, the median PFS with RAF-2i responders (PFS-2) improved at 12.8 months compared to 11.4 months with RAF-1i responders. The median OS from retreatment with RAF-2i was 15.5 months (11.1-30.8 m). Further prospective studies are needed to validate these results and expand targeted therapy options for RAF-aberrant cancers.

RESUMEN

Background: Transcatheter aortic valve replacement (TAVR) are not offered equitably to vulnerable population groups. Adequate levels of insurance may narrow gaps among patients with higher social vulnerability index (SVI). Among a national population of individuals with commercial or Medicare insurance, we sought to determine whether SVI was associated with urgency of receipt of TAVR for aortic stenosis. Methods and results: Using Optum's de-identified Clinformatics Data Mart Database (CDM), we identified admissions for TAVR with aortic stenosis between January 2018 and March 2022. Admission urgency was identified by CDM claims codes. SVI was cross-referenced to patient zip codes and grouped into quintiles. Generalized linear mixed effects models were used to predict the probability of a TAVR admission being urgent based on SVI quintiles, adjusting for patient and hospital-level covariates. Results: Among 6680 admissions for TAVR [median age 80 years (interquartile range 75-85), 43.9 % female], 8.5 % (n = 567) were classified as urgent. After adjusting for patient and hospital-level variables, there were no significant differences in the odds of urgent admission for TAVR according to SVI quintiles [OR 5th (greatest social vulnerability) vs 1st quintile (least social vulnerability): 1.29 (95 % CI: 0.90-1.85)]. Conclusions: Among commercial or Medicare beneficiaries with aortic stenosis, SVI was not associated with admission urgency for TAVR. To clarify whether cardiovascular care delivery is improved across SVI with higher paying beneficiaries, future investigation should identify whether relationships between SVI and TAVR urgency vary for Medicaid beneficiaries compared to commercial beneficiaries.

RESUMEN

Unintentional overdose is a leading driver of maternal death in Colorado. The high volume of maternal deaths from preventable causes lends questions to failures in our clinical and community-based care for pregnant and postpartum people. The Colorado Maternal Mortality Review Committee identified 3 main contributors including stigma in the community and health care system, fragmentation of the health care system, and the need for more clinician training. The Colorado Perinatal Care Quality Collaborative led a 3-pronged intervention to address these challenges and improve perinatal care. The first intervention, the Colorado Alliance for Innovation on Maternal Health Substance Use Disorder quality improvement initiative, partnered with birthing hospitals statewide to institute universal screening and timely referral for individuals at risk of substance use disorder (SUD) and perinatal mood and anxiety disorders. The second intervention, the Improve Perinatal Access, Coordination, and Treatment for Behavioral Health initiative, established a perinatal support network within communities. This program assists individuals with SUD, perinatal mood and anxiety disorders, or social needs to navigate the perinatal period. The third intervention, the Colorado Maternal Overdose Matters Plus program, has enhanced in-hospital access to pharmacotherapy for pregnant and postpartum individuals with SUD through training and technical support. These collaborative initiatives aim to minimize barriers to care by integrating inpatient screening, treatment referrals, pharmacotherapy access, and community care support to mitigate maternal mortality in Colorado.

RESUMEN

The neighborhoods where individuals reside shape environmental exposures, access to resources, and opportunities. The inequitable distribution of resources and opportunities across neighborhoods perpetuates and exacerbates cardiovascular health inequities. Thus, interventions that address the neighborhood environment could reduce the inequitable burden of cardiovascular disease in disenfranchised populations. The objective of this scientific statement is to provide a roadmap illustrating how current knowledge regarding the effects of neighborhoods on cardiovascular disease can be used to develop and implement effective interventions to improve cardiovascular health at the population, health system, community, and individual levels. PubMed/Medline, CINAHL, Cochrane Library reviews, and ClinicalTrials.gov were used to identify observational studies and interventions examining or targeting neighborhood conditions in relation to cardiovascular health. The scientific statement summarizes how neighborhoods have been incorporated into the actions of health care systems, interventions in community settings, and policies and interventions that involve modifying the neighborhood environment. This scientific statement presents promising findings that can be expanded and implemented more broadly and identifies methodological challenges in designing studies to evaluate important neighborhood-related policies and interventions. Last, this scientific statement offers recommendations for areas that merit further research to promote a deeper understanding of the contributions of neighborhoods to cardiovascular health and health inequities and to stimulate the development of more effective interventions.

RESUMEN

Many plant species exhibit strong seed dormancy. This attribute benefits the species' long-term survival but can impede restoration when rapid establishment is required. Soaking seeds in gibberellic acid (GA3) can overcome dormancy and increase germination but this treatment may not be effective outside the laboratory. An easier and potentially more effective method to apply this hormone is to coat seeds with a GA3-impregnated polymer. Seed dormancy can also be mitigated by creating a favorable microsite with increased soil moisture. We compared the emergence and establishment of penstemon seeds coated with GA3 to those of uncoated seeds planted in shallow drill rows versus deep, U-shaped furrows. Overall, 6 times more Palmer's penstemon (Penstemon palmeri; p < 0.01) and 21 times more thickleaf penstemon (P. pachyphyllus; p < 0.001) established when coated with GA3, but GA3 coating did not affect the establishment of firecracker penstemon (P. eatonii; p = 1). Establishment was higher from deep furrows than shallow rows (p < 0.001). These results indicate that GA3 seed coating and deep, U-shaped furrows may improve the restoration success of some native forbs by breaking dormancy and providing a favorable microsite. Land managers could use these techniques to restore native forbs in dry, disturbed areas.

RESUMEN

The current literature supports the positive relationship between time in nature and the improvement in children's health and identifies early childhood education (ECE) settings as an avenue for intervention. Unfortunately, access to both outdoor time and ECE opportunities is lower in communities facing economic adversity. Efforts are needed to identify the best approaches to incorporate outdoor time in ECE settings, especially in communities facing socioeconomic adversity. The objectives of this research were to use a mixed methods approach to identify (1) barriers and solutions to the integration of outdoor time in ECE settings, (2) if outdoor time is a priority in ECE settings compared to other ECE priorities, and (3) how socioeconomic status influences ECE priorities and barriers for outdoor time, and health outcomes. Fourteen focus groups were conducted (n = 50) in the United States (US) with participants from three stakeholder groups: outdoor educators, parents of children attending outdoor preschool, and community members with children. Participants completed a survey (n = 49) to evaluate demographics, views on ECE and outdoor time, and health characteristics. Exploratory analyses of F as an effect modifier were conducted. The survey results showed that parents prioritized social and emotional learning and outdoor time when selecting an ECE setting for their child. The barriers identified include financial challenges and the limited availability of ECE programs. The solutions discussed included increased availability and financial support. Low income was correlated with higher rates of anxiety and increased outdoor time was a potential protective factor. These insights inform interventions to enhance outdoor time in ECE settings, with the goal of reducing disparities and promoting children's overall health.

RESUMEN

A growing body of literature suggests that outdoor time is beneficial for physical and mental health in childhood. Profound disparities exist in access to outdoor spaces (and the health benefits thereof) for children in communities of color. The objectives of this research were to: (1) identify challenges and solutions to outdoor time for children; (2) assess the importance of outdoor time for children; and (3) evaluate results stratified by race/ethnicity. Using a convergent mixed methods approach, we conducted a thematic analysis from 14 focus groups (n = 50) with outdoor educators, parents with children attending outdoor preschools, and community members with children. In addition, 49 participants completed a survey to identify challenges and solutions, perceived importance, and culturally relevant perspectives of outdoor time. The main challenges identified for outdoor time were safety concerns, inclement weather, lack of access to outdoor spaces, and parent work schedules. The primary proposed solution was integrating outdoor time into the school day. Nearly all participants, independent of racial identity, reported that outdoor time improved physical and mental health. Overall outdoor time was lower in participants from communities of color (~8 h/week) compared to their White counterparts (~10 h/week). While 50% of people of color (POC) reported that outdoor time was an important cultural value, only 18% reported that people in their respective culture spent time outside. This work contributes to accumulating knowledge that unique barriers to outdoor time exist for communities of color, and the children that live, learn, and play in these communities. Increasing outdoor time in school settings offers a potential solution to reduce identified barriers and to promote health equity in childhood.

RESUMEN

Background Patients experience atrial fibrillation (AF) as a complex disease given its adversity, chronicity, and necessity for long-term treatments. Few studies have examined the experience of rural individuals with AF. We conducted qualitative assessments of patients with AF residing in rural, western Pennsylvania to identify barriers and facilitators to care. Methods and Results We conducted 8 semistructured virtual focus groups with 42 individuals living in rural western Pennsylvania using contextually tailored questions to assess participant perspectives. We inductively analyzed focus group transcripts using paragraph-by-paragraph and focused coding to identify themes with the qualitative description approach. We used Krippendorff α scoring to determine interreviewer reliability. We harnessed investigator triangulation to augment the reliability of our findings. We reached thematic saturation after coding 8 focus groups. Participants were 52.4% women, with a median age of 70.9 years (range, 54.5-82.0 years), and most were White race (92.9%). Participants identified medication costliness, invisibility of AF to others, and lack of emergent transportation as barriers to care. Participants described interpersonal support and use of technology as important for AF self-care, and expressed ambivalence about how relationships with health care providers affected AF care. Conclusions Focus group participants described multiple social and structural barriers to care for AF. Our findings highlight the complexity of the experience of individuals with AF residing in rural western Pennsylvania.

RESUMEN

BACKGROUND: Black patients with peripartum cardiomyopathy (PPCM) have disproportionately worse outcomes than White patients, possibly related to variable involvement of cardiovascular specialists in their clinical care. We sought to determine whether race was associated with cardiology involvement in clinical care during inpatient admission and whether cardiology involvement in care was associated with higher claims of guideline-directed medical therapy (GDMT) a week after hospital discharge. METHODS: Using Optum's de-identified Clinformatics® Data Mart (CDM), we included Black and White patients' first hospital admission for PPCM from 2008 to 2021. Cardiology involvement in clinical care was defined as the receipt of attending care from a cardiovascular specialist during admission. GDMT included beta-blockers (BB) for all patients and triple therapy (BB, angiotensin-responsive medications, and mineralocorticoid receptor antagonists) for non-pregnant patients. Logistic regression was used to determine the associations between cardiology involvement in clinical care during admission and (1) patient race and (2) GDMT prescription, adjusting for age and comorbidities. RESULTS: Among 668 patients (32.6% Black, 67.4% White, 93.3% commercially insured), there was no significant difference in the odds of cardiology involvement in clinical care by race (aOR: 1.41; 95%CI: 0.87-2.33, P=0.17). Inpatient cardiology care was associated with 2.75 times increased odds of having a prescription claim for GDMT (BB) for White patients (aOR: 2.75; 95%CI 1.50-5.06, P=0.001), and the estimated effect size was similar but not statistically significant for Black patients (aOR: 2.20, 95% CI, 0.84-5.71, P=0.11). The interaction between race and cardiology involvement in clinical care was not statistically significant for the receipt of BB prescription. Among 274 non-pregnant patients with PPCM (37.2% Black, 62.8% White), 5.8% received triple GDMT. Of these, none of the Black patients lacking cardiology care had triple GDMT. However, cardiology involvement in care was not significantly associated with triple GDMT for either race. CONCLUSIONS: Among a commercially insured population within PPCM, race was not associated with cardiology involvement in clinical care during hospitalization. However, cardiology involvement in care was associated with significantly higher odds of prescription claims for BB for only White patients. Additional strategies are needed to support equitable GDMT prescription.

RESUMEN

Over the past 15 years, rapid progress has been made in developmental therapeutics, especially regarding the use of matched targeted therapies against specific oncogenic molecular alterations across cancer types. Molecular tumour boards (MTBs) are panels of expert physicians, scientists, health-care providers and patient advocates who review and interpret molecular-profiling results for individual patients with cancer and match each patient to available therapies, which can include investigational drugs. Interpretation of the molecular alterations found in each patient is a complicated task that requires an understanding of their contextual functional effects and their correlations with sensitivity or resistance to specific treatments. The criteria for determining the actionability of molecular alterations and selecting matched treatments are constantly evolving. Therefore, MTBs have an increasingly necessary role in optimizing the allocation of biomarker-directed therapies and the implementation of precision oncology. Ultimately, increased MTB availability, accessibility and performance are likely to improve patient care. The challenges faced by MTBs are increasing, owing to the plethora of identifiable molecular alterations and immune markers in tumours of individual patients and their evolving clinical significance as more and more data on patient outcomes and results from clinical trials become available. Beyond next-generation sequencing, broader biomarker analyses can provide useful information. However, greater funding, resources and expertise are needed to ensure the sustainability of MTBs and expand their outreach to underserved populations. Harmonization between practice and policy will be required to optimally implement precision oncology. Herein, we discuss the evolving role of MTBs and current and future considerations for their use in precision oncology.

Each year, new drugs are introduced to the market, representing structures that have affinity for biological targets implicated in human diseases and conditions. These new chemical entities (NCEs), particularly small molecules and antibody-drug conjugates, provide insight into molecular recognition and serve as potential leads for the design of future medicines. This annual review is part of a continuing series highlighting the most likely process-scale synthetic approaches to 35 NCEs that were first approved anywhere in the world during 2021.
