RESUMO

Background and Aim: This study investigates temporal trends in gastrointestinal cancer-related mortality in the United States between 1999 and 2020, focusing on differences by sex, age, and race. Methods: We investigated the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research multiple causes of death database (Years 1999-2020) for gastrointestinal cancer-related mortality with a focus on the underlying cause of death. Results: A total of 3 115 243 gastrointestinal cancer-related deaths occurred from 1999 to 2020. The overall age-adjusted mortality rate decreased from 46.7 per 100 000 in 1999 to 38.4 per 100 000 in 2020. The average annual percent change (AAPC) for the study period was -0.9% (95% CI: -1.0%, -0.9%, P < 0.001), with no significant difference in AAPC between the sexes but some difference between races and related to individual cancers. African Americans and Asian Americans, and Pacific Islanders experienced a greater decrease in mortality compared with Whites. Mortality rates for American Indian and Alaskan Native populations also decreased significantly from 1999 to 2020 (P < 0.001). There were significant declines in esophageal, stomach, colon, rectal, and gallbladder cancer-related mortality but increases in the small bowel, anal, pancreatic, and hepatic cancer-related mortality (P < 0.001), with variation across different sexes and racial groups. Conclusion: While overall gastrointestinal cancer-related mortality declined significantly in the United States from 1999 to 2020, mortality from some cancers increased. Furthermore, differences between sexes and racial groups underscore crucial differences in gastrointestinal cancer mortality, highlighting areas for future research.

RESUMO

PURPOSE: Breast cancer molecular subtypes show significant differences in different ethnic groups in the United States, but no study has evaluated genetic ancestry in breast cancer in Brazilian women. METHODS: Breast cancer patients from distinct parts of Brazil were evaluated. Molecular subtypes were determined by immunohistochemistry. Genetic ancestry was evaluated using a panel of 46 AIMs (ancestry informative markers), which classified genetic ancestry as European, African, Asian, and Amerindian. PCR products were subjected to capillary electrophoresis and analyzed using GeneMapper 4.0 software. Ancestry was evaluated with Structure v.2.3.3 software. Ancestry was tested for correlations with geographic region and molecular subtype. The chi-square test and ANOVA with Bonferroni adjustment were applied. RESULTS: Genetic ancestry and clinical data were evaluated in 1127 patients. Higher rates of self-reported white ethnicity, European ancestry, and HER-2- luminal tumors were identified in the South region, which may influence age at diagnosis and result in a higher rate of early tumors. Conversely, higher rates of African ancestry in the North and Northeast regions, self-reported nonwhite ethnicity, HER-2+ tumors, and triple-negative tumors were noted. Triple-negative and HER-2+ tumors were associated with higher advanced and metastatic disease rates at diagnosis, with triple-negative tumors being more frequent in young women. CONCLUSION: Differences in genetic ancestry, self-reported ethnicity, and molecular subtype were found between Brazilian demographic regions. Knowledge of these features may contribute to a better understanding of age at diagnosis and the molecular distribution of breast cancer in Brazil.

RESUMO

Machine learning models are often trained on sociodemographic features to predict mental health outcomes. Biases in the collection of race-related data can limit the development of useful and fair models. To assess the current state of this data in mental health research, we conducted a rapid review guided by Critical Race Theory. Findings reveal limitations in the measurement and reporting of race and ethnicity, potentially leading to models that amplify health inequities.

RESUMO

Resumo Fundamento Aparentemente, a pior resposta a algumas classes de anti-hipertensivos, especialmente inibidores da enzima conversora da angiotensina e bloqueadores de receptor de angiotensina, pela população negra, explicaria, pelo menos parcialmente, o pior controle da hipertensão entre esses indivíduos. Entretanto, a maioria das evidências vêm de estudos norte-americanos. Objetivos Este estudo tem o objetivo de investigar a associação entre raça/cor da pele autorrelatadas e controle de PA em participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) utilizando várias classes de anti-hipertensivos em monoterapia. Métodos O estudo envolveu uma análise transversal, realizada com participantes da linha de base do ELSA-Brasil. O controle de pressão arterial foi a variável de resposta, participantes com valores de PA ≥140/90 mmHg foram considerados descontrolados em relação aos níveis de pressão arterial. A raça/cor da pele foi autorrelatada (branco, pardo, negro). Todos os participantes tiveram que responder perguntas sobre uso contínuo de medicamentos. A associação entre o controle de PA e raça/cor da pele foi estimada por regressão logística. O nível de significância adotado nesse estudo foi de 5%. Resultados Do total de 1.795 usuários de anti-hipertensivos em monoterapia na linha de base, 55,5% se declararam brancos, 27,9%, pardos e 16,7%, negros. Mesmo depois de padronizar em relação a variáveis de confusão, negros em uso de inibidores da enzima conversora de angiotensina (IECA), bloqueadores de receptor de angiotensina (BRA), diuréticos tiazídicos (DIU tiazídicos) e betabloqueadores (BB) in monoterapia tinham controle de pressão arterial pior em comparação a brancos. Conclusões Os resultados deste estudo sugerem que, nesta amostra de brasileiros adultos utilizando anti-hipertensivos em monoterapia, as diferenças de controle de pressão arterial entre os vários grupos raciais não são explicadas pela possível eficácia mais baixa dos IECA e BRA em indivíduos negros.


Abstract Background It seems that the worst response to some classes of antihypertensive drugs, especially angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, on the part of the Black population, would at least partially explain the worse control of hypertension among these individuals. However, most of the evidence comes from American studies. Objectives This study aims to investigate the association between self-reported race/skin color and BP control in participants of the Longitudinal Study of Adult Health (ELSA-Brasil), using different classes of antihypertensive drugs in monotherapy. Methods The study involved a cross-sectional analysis, carried out with participants from the baseline of ELSA-Brasil. Blood pressure control was the response variable, participants with BP values ≥140/90 mmHg were considered out of control in relation to blood pressure levels. Race/skin color was self-reported (White, Brown, Black). All participants were asked about the continuous use of medication. Association between BP control and race/skin color was estimated through logistic regression. The level of significance adopted in this study was of 5%. Results Of the total of 1,795 users of antihypertensive drugs in monotherapy at baseline, 55.5% declared themselves White, 27.9% Brown, and 16.7% Black. Even after adjusting for confounding variables, Blacks using angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blocker (ARB), thiazide diuretics (thiazide DIU), and beta-blockers (BB) in monotherapy had worse blood pressure control compared to Whites. Conclusions Our results suggest that in this sample of Brazilian adults using antihypertensive drugs in monotherapy, the differences in blood pressure control between different racial groups are not explained by the possible lower effectiveness of ACEIs and ARBs in Black individuals.

RESUMO

BACKGROUND: Black individuals have high incident diabetes risk, despite having paradoxically lower triglyceride and higher HDL (high-density lipoprotein) cholesterol levels. The basis of this is poorly understood. We evaluated the participants of SPRINT (Systolic Blood Pressure Intervention Trial) to assess the association of estimated European genetic ancestry with the risk of incident diabetes in self-identified Black individuals. METHODS: Self-identified non-Hispanic Black SPRINT participants free of diabetes at baseline were included. Black participants were stratified into tertiles (T1-T3) of European ancestry proportions estimated using 106 biallelic ancestry informative genetic markers. The multivariable-adjusted association of European ancestry proportion with indices of baseline metabolic syndrome (ie, fasting plasma glucose, triglycerides, HDL cholesterol, body mass index, and blood pressure) was assessed. Multivariable-adjusted Cox regression determined the risk of incident diabetes (fasting plasma glucose ≥126 mg/dL or self-reported diabetes treatment) across tertiles of European ancestry proportion. RESULTS: Among 2466 Black SPRINT participants, a higher European ancestry proportion was independently associated with higher baseline triglyceride and lower HDL cholesterol levels (P<0.001 for both). European ancestry proportion was not associated with baseline fasting plasma glucose, body mass index, and blood pressure (P>0.05). Compared with the first tertile, those in the second (hazard ratio, 0.64 [95% CI, 0.45-0.90]) and third tertiles (hazard ratio, 0.61 [95% CI, 0.44-0.89]) of the European ancestry proportion had a lower risk of incident diabetes. A 5% point higher European ancestry was associated with a 29% lower risk of incident diabetes (hazard ratio, 0.71 [95% CI, 0.55-0.93]). There was no evidence of a differential association between the European ancestry proportion tertiles and incident diabetes between those randomized to intensive versus standard blood pressure treatment. CONCLUSIONS: The higher risk of incident diabetes in Black individuals may have genetic determinants in addition to adverse social factors. Further research may help understand the interplay between biological and social determinants of cardiometabolic health in Black individuals.

RESUMO

BACKGROUND: Vitamin E (vitE) is hypothesized to attenuate age-related decline in pulmonary function. OBJECTIVES: We investigated the association between change in plasma vitE (∆vitE) and pulmonary function decline [forced expiratory volume in the first second (FEV1)] and examined genetic and nongenetic factors associated with ∆vitE. METHODS: We studied 1144 men randomly assigned to vitE in SELECT (Selenium and Vitamin E Cancer Prevention Trial). ∆vitE was the difference between baseline and year 3 vitE concentrations measured with GC-MS. FEV1 was measured longitudinally by spirometry. We genotyped 555 men (vitE-only arm) using the Illumina Expanded Multi-Ethnic Genotyping Array (MEGAex). We used mixed-effects linear regression modeling to examine the ∆vitE-FEV1 association. RESULTS: Higher ∆vitE was associated with lower baseline α-tocopherol (α-TOH), higher baseline γ-tocopherol, higher baseline free cholesterol, European ancestry (as opposed to African) (all P < 0.05), and the minor allele of a missense variant in cytochrome P450 family 4 subfamily F member 2 (CYP4F2) (rs2108622-T; 2.4 µmol/L higher ∆vitE, SE: 0.8 µmol/L; P = 0.0032). Higher ∆vitE was associated with attenuated FEV1 decline, with stronger effects in adherent participants (≥80% of supplements consumed): a statistically significant ∆vitE × time interaction (P = 0.014) indicated that a 1-unit increase in ∆vitE was associated with a 2.2-mL/y attenuation in FEV1 decline (SE: 0.9 mL/y). The effect size for 1 SD higher ∆vitE (+4 µmol/mmol free-cholesterol-adjusted α-TOH) was roughly one-quarter of the effect of 1 y of aging, but in the opposite direction. The ∆vitE-FEV1 association was similar in never smokers (2.4-mL/y attenuated FEV1 decline, SE: 1.0 mL/y; P = 0.017, n = 364), and current smokers (2.8-mL/y, SE: 1.6 mL/y; P = 0.079, n = 214), but there was little to no effect in former smokers (-0.64-mL/y, SE: 0.9 mL/y; P = 0.45, n = 564). CONCLUSIONS: Greater response to vitE supplementation was associated with attenuated FEV1 decline. The response to supplementation differed by rs2108622 such that individuals with the C allele, compared with the T allele, may need a higher dietary intake to reach the same plasma vitE concentration.

RESUMO

BACKGROUND AND PURPOSE: Coronavirus disease 2019 (COVID-19) may be associated with increased risk for ischemic stroke. We present prevalence and characteristics of strokes in patients with laboratory-confirmed severe acute respiratory syndrome coronavirus-2 infection enrolled in the American Heart Association COVID-19 Cardiovascular Disease Registry. METHODS: In this quality improvement registry study, we examined demographic, baseline clinical characteristics, and in-hospital outcomes among hospitalized COVID-19 patients. The primary outcomes were ischemic stroke or transient ischemic attack (TIA) and in-hospital death. RESULTS: Among 21 073 patients with COVID-19 admitted at 107 hospitals between January 29, 2020, and November 23, 2020, 160 (0.75%) experienced acute ischemic stroke/TIA (55.3% of all acute strokes) and 129 (0.61%) had other types of stroke. Among nonischemic strokes, there were 44 (15.2%) intracerebral hemorrhages, 33 (11.4%) subarachnoid hemorrhages, 21 (7.3%) epidural/subdural hemorrhages, 2 (0.7%) cerebral venous sinus thromboses, and 24 (8.3%) strokes not otherwise classified. Asians and non-Hispanic Blacks were overrepresented among ischemic stroke/TIA patients compared with their overall representation in the registry, but adjusted odds of stroke did not vary by race. Median time from COVID-19 symptom onset to ischemic stroke was 11.5 days (interquartile range, 17.8); median National Institutes of Health Stroke Scale score was 11 (interquartile range, 17). COVID-19 patients with acute ischemic stroke/TIA had higher prevalence of hypertension, diabetes, and atrial fibrillation compared with those without stroke. Intensive care unit admission and mechanical ventilation were associated with higher odds of acute ischemic stroke/TIA, but older age was not a predictor. In adjusted models, acute ischemic stroke/TIA was not associated with in-hospital mortality. CONCLUSIONS: Ischemic stroke risk did not vary by race. In contrast to the association between older age and death from COVID-19, ischemic stroke risk was the highest among middle-aged adults after adjusting for comorbidities and illness severity, suggesting a potential mechanism for ischemic stroke in COVID-19 independent of age-related atherosclerotic pathways.

RESUMO

OBJECTIVE: To determine differences in obesity, type 2 diabetes, and hypertension in Black patients compared with White patients with multiple sclerosis (MS). DESIGN: Cross-sectional database review. SETTING: Large academic medical center research records database. PARTICIPANTS: A total of 3191 patient cases (N=3191; 77% female, 34% Black) identified by MS diagnosis within the medical record. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Diagnosis codes for type 2 diabetes and hypertension. Body mass index (BMI), race, age, and sex were collected. Analysis of variance (continuous variables) and chi-square analyses (categorical variables) were conducted to determine differences in obesity, diabetes, and hypertension between race and sex. Logistic regression was conducted to determine odds ratios (ORs) of developing diabetes and hypertension based on race, sex, BMI, and age. RESULTS: Black patients were more than twice as likely to be diagnosed as having diabetes (OR, 2.15 [95% CI, 1.70-2.72]; P<.0001) or hypertension (OR, 2.44 [95% CI, 2.05-2.91], P<.0001) compared with White patients. Sex did not present a greater likelihood of being diagnosed as having diabetes; however, men were 1.22 times more likely be diagnosed as having hypertension compared with women (95% CI, 1.01-1.49; P=.0439). Increased age and BMI were also significantly associated with likelihood of diagnosis of diabetes and hypertension (age: diabetes OR, 1.05 [95% CI, 1.04-1.06], P<.0001; hypertension OR, 1.06 [95% CI, 1.05-1.06], P<.0001; BMI: diabetes obese vs normal: OR, 2.11 [95% CI, 1.43-3.11], P=.0002; hypertension: obese vs normal: OR, 1.72 [95% CI, 1.39-2.13], P<.0001). CONCLUSIONS: Black patients with MS are significantly more likely to have cardiometabolic conditions than White patients. These conditions have been associated with poorer health outcomes for people with MS and may have some effect on the differences in MS disease course reported in Black patients.

RESUMO

ABSTRACT Objectives: to discuss the influence of urban poverty on the context of violence among adolescents from an intersectional perspective. Methods: the original research, of the action research type, analyzed data from 13 workshops. The participants were adolescents from both sexes, from 15 to 17 years old, from a public school in a peripheral neighborhood of São Paulo, SP. The methodological proposition of intersectional analysis guided the interpretation of the empirical material. Results: the intersection of class and gender may increase the (re)production of violence in some men. The intersection of race/color, social class, and territory contributes to the construction of narratives that naturalize inequality and, thus, justify discrimination. Final Considerations: there is necessity of new public policies that consider the social contexts and experiences of the subjects that stem from the articulation of social markers.

RESUMO

RESUMO O número de mulheres pesquisadoras tem crescido mundialmente. No entanto, as desigualdades de gênero persistem em quatro aspectos: as mulheres ainda representam parcela minoritária na ciência mundial; concentram-se em determinadas áreas de conhecimento; predominam nos níveis iniciais da carreira e são sub-representadas em posições deliberativas da política científica e tecnológica. No Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), apesar do aumento de mulheres bolsistas de Produtividade em Pesquisa (PQ) nas últimas décadas, as assimetrias permanecem. Este estudo visou discutir as assimetrias de gênero e raça nas diferentes áreas do conhecimento, em particular na psicologia, tomando como analisador a distribuição de bolsas (PQ) do CNPq. Utilizaram-se dados disponibilizados pelo CNPq e coletados por meio de SurveyMonkey. As desigualdades de gênero na ciência persistem no sistema científico brasileiro: as mulheres são minoria entre os bolsistas PQ/CNPq, concentram-se em guetos disciplinares e enfrentam dificuldades tanto para acessar o sistema PQ quanto para alcançar as modalidades de bolsa de maior prestígio científico. Na psicologia, apesar da presença em todas as modalidades de bolsa, ocupam proporcionalmente menos posições no topo da carreira. Ademais, há invisibilidade de mulheres negras e indígenas, a qual tem suas raízes no projeto moderno colonial.


ABSTRACT The number of women researchers has grown worldwide. However, gender inequalities persist in four aspects: women still represent a minority share in world science; they are concentrated in certain fields of knowledge; they predominate in early career levels; and they are underrepresented in deliberative positions of science and technology policies. At the National Council for Scientific and Technological Development (CNPq), despite the increase in women Research Productivity Scholars (PQ) in recent decades, the asymmetries remain. This study aims to discuss the asymmetries of gender and race in different fields of knowledge, particularly in Psychology, taking as an analyzer the distribution of grants (PQ) by the CNPq. Data made available by the CNPq and collected through SurveyMonkey were used. Gender inequalities in science persist in the Brazilian scientific system: women are a minority among the PQ/CNPq fellows, they are concentrated in disciplinary ghettos and face difficulties both to access the PQ system, and to reach the most prestigious scientific fellowships. In Psychology, despite their presence in all the scholarship modalities, they occupy proportionally fewer positions at the top of the career. In addition, there is the invisibility of black and indigenous women, which has its roots in the modern colonial project.

RESUMO

BACKGROUND: The objective of this study was to evaluate the association between self-identified race and overall survival (OS), progression-free survival (PFS), and response to therapy among patients enrolled in the randomized Cancer and Leukemia Group B (CALGB)/SWOG 80405 trial. METHODS: Patients with advanced or metastatic colorectal cancer who were enrolled in the CALGB/SWOG 80405 trial were identified by race. On the basis of covariates (treatment arm, KRAS status, sex, age, and body mass index), each Black patient was exact matched with a White patient. The association between race and OS and PFS was examined using a marginal Cox proportional hazard model for matched pairs. The interaction between KRAS status and race was tested in the model. The association between race and response to therapy and adverse events were examined using a marginal logistic regression model. RESULTS: In total, 392 patients were matched and included in the final data set. No difference in OS (hazard ratio [HR], 0.92; 95% confidence interval [CI], 0.73-1.16), PFS (HR, 0.97; 95% CI, 0.78-1.20), or response to therapy (odds ratio [OR], 1.00; 95% CI, 0.65-1.52) was observed between Black and White patients. Patients with KRAS mutant status (HR, 1.31; 95% CI, 1.02-1.67), a performance statusscore of 1 (reference, a performance status of 0; HR, 1.49; 95% CI, 1.18-1.88), or ≥3 metastatic sites (reference, 1 metastatic site; HR, 1.67; 95% CI, 1.22-2.28) experienced worse OS. Black patients experienced lower rates and risk of grade ≥3 fatigue (6.6% vs 13.3%; OR, 0.46; 95% CI, 0.24-0.91) but were equally likely to be treated with a dose reduction (OR, 1.09; 95% CI, 0.72-1.65). CONCLUSIONS: No difference in OS, PFS, or response to therapy was observed between Black patients and White patients in an equal treatment setting of the CALGB/SWOG 80405 randomized controlled trial. LAY SUMMARY: Despite improvements in screening and treatment, studies have demonstrated worse outcomes in Black patients with colorectal cancer. The purpose of this study was to determine whether there was a difference in cancer-specific outcomes among Black and White patients receiving equivalent treatment on the CALGB/SWOG 80405 randomized clinical trial. In this study, there was no difference in overall survival, progression-free survival, or response to therapy between Black and White patients treated on a clinical trial. These findings suggest that access to care and differences in treatment may be responsible for racial disparities in colorectal cancer.

RESUMO

BACKGROUND: Individuals of South Asian ancestry represent 23% of the global population, corresponding to 1.8 billion people, and have substantially higher risk of atherosclerotic cardiovascular disease compared with most other ethnicities. US practice guidelines now recognize South Asian ancestry as an important risk-enhancing factor. The magnitude of enhanced risk within the context of contemporary clinical care, the extent to which it is captured by existing risk estimators, and its potential mechanisms warrant additional study. METHODS: Within the UK Biobank prospective cohort study, 8124 middle-aged participants of South Asian ancestry and 449 349 participants of European ancestry who were free of atherosclerotic cardiovascular disease at the time of enrollment were examined. The relationship of ancestry to risk of incident atherosclerotic cardiovascular disease-defined as myocardial infarction, coronary revascularization, or ischemic stroke-was assessed with Cox proportional hazards regression, along with examination of a broad range of clinical, anthropometric, and lifestyle mediators. RESULTS: The mean age at study enrollment was 57 years, and 202 405 (44%) were male. Over a median follow-up of 11 years, 554 of 8124 (6.8%) individuals of South Asian ancestry experienced an atherosclerotic cardiovascular disease event compared with 19 756 of 449 349 (4.4%) individuals of European ancestry, corresponding to an adjusted hazard ratio of 2.03 (95% CI, 1.86-2.22; P<0.001). This higher relative risk was largely consistent across a range of age, sex, and clinical subgroups. Despite the >2-fold higher observed risk, the predicted 10-year risk of cardiovascular disease according to the American Heart Association/American College of Cardiology Pooled Cohort equations and QRISK3 equations was nearly identical for individuals of South Asian and European ancestry. Adjustment for a broad range of clinical, anthropometric, and lifestyle risk factors led to only modest attenuation of the observed hazard ratio to 1.45 (95% CI, 1.28-1.65, P<0.001). Assessment of variance explained by 18 candidate risk factors suggested greater importance of hypertension, diabetes, and central adiposity in South Asian individuals. CONCLUSIONS: Within a large prospective study, South Asian individuals had substantially higher risk of atherosclerotic cardiovascular disease compared with individuals of European ancestry, and this risk was not captured by the Pooled Cohort Equations.

RESUMO

Racial/ethnic discrimination may contribute to the risk of type 2 diabetes mellitus (T2DM), but few studies have prospectively examined this relationship among racially/ethnically diverse populations. We analyzed prospective data from 33,833 eligible Sister Study participants enrolled from 2003 to 2009. In a follow-up questionnaire (2008-2012), participants reported their lifetime experiences of everyday and major forms of racial/ethnic discrimination. Self-reported physician diagnoses of T2DM were ascertained through September 2017. Hazard ratios and 95% confidence intervals were estimated using Cox proportional hazards models, overall and by race/ethnicity. Mean age at enrollment was 54.9 (standard deviation, 8.8) years; 90% of participants self-identified as non-Hispanic (NH) White, 7% as NH Black, and 3% as Hispanic/Latina. Over an average of 7 years of follow-up, there were 1,167 incident cases of T2DM. NH Black women most frequently reported everyday (75%) and major (51%) racial/ethnic discrimination (vs. 4% and 2% of NH White women, respectively, and 32% and 16% of Hispanic/Latina women, respectively). While everyday discrimination was not associated with T2DM risk, experiencing major discrimination was marginally associated with higher T2DM risk overall (hazard ratio = 1.26, 95% confidence interval: 0.99, 1.61) after adjustment for sociodemographic characteristics and body mass index. Associations were similar across racial/ethnic groups; however, racial/ethnic discrimination was more frequently reported among racial/ethnic minority women. Antidiscrimination efforts may help mitigate racial/ethnic disparities in T2DM risk.

RESUMO

BACKGROUND: Increased left ventricular (LV) mass is associated with adverse cardiovascular events including heart failure (HF). Both increased LV mass and HF disproportionately affect Black individuals. To understand the underlying mechanisms, we undertook a proteomic screen in a Black cohort and compared the findings to results from a White cohort. METHODS: We measured 1305 plasma proteins using the SomaScan platform in 1772 Black participants (mean age, 56 years; 62% women) in JHS (Jackson Heart Study) with LV mass assessed by 2-dimensional echocardiography. Incident HF was assessed in 1600 participants. We then compared protein associations in JHS to those observed in White participants from FHS (Framingham Heart Study; mean age, 54 years; 56% women). RESULTS: In JHS, there were 110 proteins associated with LV mass and 13 proteins associated with incident HF hospitalization with false discovery rate <5% after multivariable adjustment. Several proteins showed expected associations with both LV mass and HF, including NT-proBNP (N-terminal pro-B-type natriuretic peptide; ß=0.04; P=2×10-8; hazard ratio, 1.48; P=0.0001). The strongest association with LV mass was novel: LKHA4 (leukotriene-A4 hydrolase; ß=0.05; P=5×10-15). This association was confirmed on an alternate proteomics platform and further supported by related metabolomic data. Fractalkine/CX3CL1 (C-X3-C Motif Chemokine Ligand 1) showed a novel association with incident HF (hazard ratio, 1.32; P=0.0002). While established biomarkers such as cystatin C and NT-proBNP showed consistent associations in Black and White individuals, LKHA4 and fractalkine were significantly different between the two groups. CONCLUSIONS: We identified several novel biological pathways specific to Black adults hypothesized to contribute to the pathophysiologic cascade of LV hypertrophy and incident HF including LKHA4 and fractalkine.

RESUMO

PURPOSE: We reviewed the available evidence regarding health disparities in kidney stone disease to identify knowledge gaps in this area. MATERIALS AND METHODS: A literature search was conducted using PubMed®, Embase® and Scopus® limited to articles published in English from 1971 to 2020. Articles were selected based on their relevance to disparities in kidney stone disease among adults in the United States. RESULTS: Several large epidemiological studies suggest disproportionate increases in incidence and prevalence of kidney stone disease among women as well as Black and Hispanic individuals in the United States, whereas other studies of comparable size do not report racial and ethnic demographics. Numerous articles describe disparities in imaging utilization, metabolic workup completion, analgesia, surgical intervention, stone burden at presentation, surgical complications, followup, and quality of life based on race, ethnicity, socioeconomic status and place of residence. Differences in urinary parameters based on race, ethnicity and socioeconomic status may be explained by both dietary and physiological factors. All articles assessed had substantial risk of selection bias and confounding. CONCLUSIONS: Health disparities are present in many aspects of kidney stone disease. Further research should focus not only on characterization of these disparities but also on interventions to reduce or eliminate them.

RESUMO

OBJECTIVE: Significant racial/ethnic disparities in poststroke function exist, but whether these disparities vary by stroke subtype is unknown. Study goals were to (1) determine if racial/ethnic disparities in the recovery of poststroke function varied by stroke subtype and (2) identify confounding factors associated with these racial/ethnic disparities. DESIGN: Secondary analysis of the 1-year Stroke Recovery in Underserved Populations Cohort Study. SETTING: Eleven inpatient rehabilitation facilities (IRFs) across the United States. PARTICIPANTS: A total of 1066 patients (n=868 with ischemic stroke and n=198 with hemorrhagic stroke, N=1066) who self-identified as White (n=813), Black (n=183), or Hispanic (n=70). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM scores at IRF admission, discharge, 3 months, and 12 months were modeled using multivariable mixed effects longitudinal regression. RESULTS: Compared with White patients, Black (-6.1 and -4.6) and Hispanic (-10.1 and -9.9) patients had significantly lower FIM scores at 3 and 12 months, respectively. A significant (P<.01) 3-way interaction (race/ethnic*subtype*time) indicated that disparities varied by stroke subtype. The stroke subtype differences were most prominent for Black-White disparities because disparities in hemorrhagic stroke were present at IRF admission (vs 3 months for ischemic stroke). Additionally, at 12 months, the magnitude of Black-White disparities was over 3 times larger for hemorrhagic stroke (-10.4) than ischemic stroke (-3.1). Age primarily influenced Black-White disparities (especially for hemorrhagic stroke), but factors that influenced Hispanic-White disparities were not identified. Sensitivity analyses showed that there were stroke subtype differences in racial/ethnic disparities for cognitive (but not motor) function, and results were robust to adjustments for missing data because of attrition. CONCLUSIONS: There are significant differences between stroke subtypes in the timing and magnitude of Black-White disparities in poststroke function. Age was a major confounding factor for Black-White disparities (particularly for hemorrhagic stroke). Overall, Hispanic patients had the lowest levels of poststroke function, and more work is needed to identify significant factors that influence Hispanic-White disparities.
