Ethnobotanical knowledge on non-conventional food plants and medicinal plants in Extractivist Reserve in the Brazilian Amazon / Conocimiento etnobotánico sobre plantas alimenticias no convencionales y plantas medicinales en una Reserva Extractivista en la Amazonía Brasileña

Information on the knowledge and ways of using food and medicinal plants by traditional populations, family farmers and Brazilian native population in the Amazon is essential to guarantee the food sovereignty of these groups. This study was conducted using semi-structured interviews applied to local respondents. A total of 269 species of both non-conventional food plants and medicinal plants were identified, distributed in 83 botanical families and 198 genera. The Arecaceae and Lamiaceae families had the highest species richness (11 and 7, respectively). The Shannon-Wiener (H') and Pielou (J') diversity indices were considered high (5.02 and 0.9, respectively) when compared to other ethnobotanical works. In the environment in which these families are found, these species become the only food and medicinal resources available.

La información sobre los saberes y formas de uso de las plantas alimenticias y medicinales por parte de las poblaciones tradicionales, agricultores familiares e indígenas brasileños en la Amazonía es fundamental para garantizar la soberanía alimentaria de estos grupos. Este estudio se realizó utilizando entrevistas semiestructuradas aplicadas a encuestados locales. Se identificaron un total de 269 especies tanto de plantas alimenticiasno convencionales como de plantas medicinales, distribuidas en 83 familias botánicas y 198 géneros. Las familias Arecaceae y Lamiaceae tuvieron la mayor riqueza de especies (11 y 7, respectivamente). Los índices de diversidad de Shannon-Wiener (H') y Pielou (J') fueron considerados altos (5,02 y 0,9, respectivamente) en comparación con otros trabajos etnobotánicos. En el ambiente en que se encuentran estas familias, estas especies se convierten en los únicos recursos alimenticios y medicinales disponibles.

EEG and fNIRS datasets based on Stroop task during two weeks of high-altitude exposure in new immigrants.

Maintaining sufficient cerebral oxygen metabolism is crucial for human survival, especially in challenging conditions such as high-altitudes. Human cognitive neural activity is sensitive to fluctuations in oxygen levels. However, there is a lack of publicly available datasets on human behavioural responses and cerebral dynamics assessments during the execution of conflicting tasks in natural hypoxic environments. We recruited 80 healthy new immigrant volunteers (males, aged 20 ± 2 years) and employed the Stroop cognitive conflict paradigm. After a two-week exposure to both high and low-altitudes, the behavioural performance, prefrontal oxygen levels, and electroencephalography (EEG) signals were recorded. Comparative analyses were conducted on the behavioural reaction times and accuracy during Stroop tasks, and statistical analyses of participants' prefrontal oxygen levels and EEG signals were performed. We anticipate that our open-access dataset will contribute to the development of monitoring devices and algorithms, designed specifically for measuring cerebral oxygen and EEG dynamics in populations exposed to extreme environments, particularly among individuals suffering from oxygen deficiency.

A scoping review of racial, ethnic, socioeconomic, and geographic disparities in the outcomes of older adults with cancer.

INTRODUCTION: Cancer health disparities are widespread. Nevertheless, the disparities in outcomes among diverse survivors of cancer ages 65 years and older ("older") have not been systematically evaluated. METHODS: We conducted a scoping review of original research articles published between January 2016 and September 2023 and indexed in Medline (Ovid), Embase, Scopus, and CINAHL databases. We included studies evaluating racial, ethnic, socioeconomic disadvantaged, geographic, sexual and gender, and/or persons with disabilities disparities in treatment, survivorship, and mortality among older survivors of cancer. We excluded studies with no a priori aims related to a health disparity, review articles, conference proceedings, meeting abstracts, studies with unclear methodologies, and articles in which the disparity group was examined only as an analytic covariate. Two reviewers independently extracted data following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis reporting guidelines. RESULTS: After searching and removing duplicates, 2573 unique citations remained and after screening 59 articles met the inclusion criteria. Many investigated more than one health disparity, and most focused on racial and ethnic (n = 44) or socioeconomic (n = 25) disparities; only 10 studies described geographic disparities, and none evaluated disparities in persons with disabilities or due to sexual and gender identity. Research investigating disparities in outcomes among diverse older survivors of cancer is increasing gradually-68% of eligible articles were published between 2020 and 2023. Most studies focused on the treatment phase of care (n = 28) and mortality (n = 26), with 16 examined disparities in survivorship, symptoms, or quality of life. Most research was descriptive and lacked analyses of potential underlying mechanisms contributing to the reported disparities. CONCLUSION: Little research has evaluated the effect of strategies to reduce health disparities among older patients with cancer. This lack of evidence perpetuates cancer inequities and leaves the cancer care system ill equipped to address the unique needs of the rapidly growing and increasingly diverse older adult cancer population.

Maternal Migration, Prenatal Stress and Child Autistic Traits: Insights From a Population-Based Cohort Study.

OBJECTIVE: There is emerging evidence for an increased prevalence of autism in children of mothers with a migration background. To date, the mechanisms underlying this relationship are poorly understood. We investigated whether prenatal stress exposure mediates the association between maternal migration and child autistic traits, assessing first- and second-generation migrant mothers in the Netherlands and their children. METHOD: The study was embedded in the prospective population-based Generation R cohort. Of the 4,727 participants, 1,773 mothers (38%) had a migration background. Prenatal stress was assessed using questionnaires related to stressful life events, family functioning, self-esteem, long-lasting difficulties, symptoms of psychopathology, social support, and perceived discrimination. Autistic traits were measured at age 6 years with the parent-reported Social Responsiveness Scale exclusively. Longitudinal multiple mediation analyses were performed. Analyses were stratified by migration origin (Europe and outside Europe) because of differences in migration characteristics. RESULTS: Maternal migration background was associated with more experienced stress and with higher child autistic trait scores (Europe: mean = 0.42, SD = 0.25; outside Europe: mean = 0.50, SD = 0.24) compared to no migration background (Netherlands: mean = 0.38, SD = 0.23; both p < .01). Prenatal stress, especially perceived discrimination and maternal psychopathology, accounted for up to half of the total effect of maternal migration, which remained after adjusting for sociodemographic factors (Bindirect = 0.035, 95% CI = 0.027, 0.043, Btotal = 0.074). CONCLUSION: Stress during pregnancy mediated the association between maternal migration status and child autistic traits. Future research should focus on early interventions to assess whether reducing prenatal stress exposure among women with a migration background can result in lower offspring autistic traits. DIVERSITY & INCLUSION STATEMENT: We worked to ensure that the study questionnaires were prepared in an inclusive way. We worked to ensure sex and gender balance in the recruitment of human participants. We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants. We actively worked to promote sex and gender balance in our author group. The author list of this paper includes contributors from the location and/or community where the research was conducted who participated in the data collection, design, analysis, and/or interpretation of the work.

[Syndromic approach in migrant patients: Fever, diarrhea, anemia, eosinophilia and chronic cough]. / Abordaje sindrómico en el paciente inmigrante: fiebre, diarrea, anemia, eosinofilia y tos crónica.

Migrant patients share the same diseases as natives, but biological or environmental differences may lead to distinct prevalence and manifestations of certain syndromes. Some common conditions in Primary Care stand out, such as fever, diarrhea, anemia, eosinophilia, and chronic cough, where it is important to have a special consideration. Fever may indicate a serious imported illness, and malaria should always be ruled out. Diarrhea is generally of infectious origin, and in most cases, management is outpatient. Anemia may indicate malnutrition or malabsorption, while eosinophilia may indicate a parasitic infection. Lastly, chronic cough may be a sign of tuberculosis, especially in immigrants from endemic areas. Family medicine holds a privileged position for the comprehensive, culturally sensitive, and person-centered approach to these conditions.

Disparities in Tuberculosis Incidence by Race and Ethnicity Among the U.S.-Born Population in the United States, 2011 to 2021 : An Analysis of National Disease Registry Data.

BACKGROUND: Elevated tuberculosis (TB) incidence rates have recently been reported for racial/ethnic minority populations in the United States. Tracking such disparities is important for assessing progress toward national health equity goals and implementing change. OBJECTIVE: To quantify trends in racial/ethnic disparities in TB incidence among U.S.-born persons. DESIGN: Time-series analysis of national TB registry data for 2011 to 2021. SETTING: United States. PARTICIPANTS: U.S.-born persons stratified by race/ethnicity. MEASUREMENTS: TB incidence rates, incidence rate differences, and incidence rate ratios compared with non-Hispanic White persons; excess TB cases (calculated from incidence rate differences); and the index of disparity. Analyses were stratified by sex and by attribution of TB disease to recent transmission and were adjusted for age, year, and state of residence. RESULTS: In analyses of TB incidence rates for each racial/ethnic population compared with non-Hispanic White persons, incidence rate ratios were as high as 14.2 (95% CI, 13.0 to 15.5) among American Indian or Alaska Native (AI/AN) females. Relative disparities were greater for females, younger persons, and TB attributed to recent transmission. Absolute disparities were greater for males. Excess TB cases in 2011 to 2021 represented 69% (CI, 66% to 71%) and 62% (CI, 60% to 64%) of total cases for females and males, respectively. No evidence was found to indicate that incidence rate ratios decreased over time, and most relative disparity measures showed small, statistically nonsignificant increases. LIMITATION: Analyses assumed complete TB case diagnosis and self-report of race/ethnicity and were not adjusted for medical comorbidities or social determinants of health. CONCLUSION: There are persistent disparities in TB incidence by race/ethnicity. Relative disparities were greater for AI/AN persons, females, and younger persons, and absolute disparities were greater for males. Eliminating these disparities could reduce overall TB incidence by more than 60% among the U.S.-born population. PRIMARY FUNDING SOURCE: Centers for Disease Control and Prevention.

Moral injury, race-related stress and post-traumatic stress disorder in a trauma-exposed Black population.

BACKGROUND: Race-related stress (RRS) is an unrecognized source of moral injury (MI)-or the emotional and/or spiritual suffering that may emerge after exposure to events that violate deeply held beliefs. Additionally, MI has not been explored as a mechanism of risk for post-traumatic stress disorder (PTSD) in trauma-exposed civilians. We examined relations among exposure to potentially morally injurious events (moral injury exposure, MIE), related distress (moral injury distress, MID), and RRS in Black Americans. Potential indirect associations between RRS and PTSD symptoms via MID were also examined. METHODS: Black Americans (n = 228; 90.4% female; Mage = 31.6 years. SDage = 12.8 years) recruited from an ongoing study of trauma completed measures assessing civilian MIE and MID, RRS, and PTSD. Bivariate correlations were conducted with MIE and MID, and mediation analysis with MID, to examine the role of MI in the relationship between RRS and PTSD symptom severity. RESULTS: MIE was significantly correlated with cultural (r = 0.27), individual (r = 0.29), and institutional (r = 0.25) RRS; MID also correlated with cultural (r = 0.31), individual (r = 0.31), and institutional (r = 0.26) RRS (ps < 0.001). We found an indirect effect of RRS on PTSD symptoms via MID (ß = 0.10, p < 0.005). CONCLUSIONS: All types of RRS were associated with facets of MI, which mediated the relationship between RRS and current PTSD symptoms. MI may be a potential mechanism through which RRS increases the risk for PTSD in Black individuals.

Race and indigeneity in human microbiome science: microbiomisation and the historiality of otherness.

This article reformulates Stephan Helmreich´s the ¨microbiomisation of race¨ as the historiality of otherness in the foundations of human microbiome science. Through the lens of my ethnographic fieldwork of a transnational community of microbiome scientists that conducted a landmark human microbiome research on indigenous microbes and its affiliated and first personalised microbiome initiative, the American Gut Project, I follow and trace the key actors, experimental systems and onto-epistemic claims in the emergence of human microbiome science a decade ago. In doing so, I show the links between the reinscription of race, comparative research on the microbial genetic variation of human populations and the remining of bioprospected data for personalised medicine. In these unpredictable research movements, the microbiome of non-Western peoples and territories is much more than a side project or a specific approach within the field: it constitutes the nucleus of its experimental system, opening towards subsequent and cumulative research processes and knowledge production in human microbiome science. The article demonstrates that while human microbiome science is articulated upon the microbial 'makeup' of non-wester(nised) communities, societies, and locales, its results and therapeutics are only applicable to medical conditions affecting rich nations (i.e., inflammatory, autoimmune, and metabolic diseases). My reformulation of ¨microbiomisation of race¨ as the condition of possibility of human microbiome science reveals that its individual dimension is sustained by microbial DNA data from human populations through bioprospecting practices and gains meaning through personalised medicine initiatives, informal online networks of pseudoscientific and commodified microbial-related evidence.

Climate change and health: The case of mapping droughts and migration pattern in Iran (2011-2016).

INTRODUCTION: Migration and mobility of population have been reported as a common reaction to drought. There is historical evidence to suggest the health effects of droughts and human migration linkage in Iran. This study aimed to map the drought and migration patterns in Iran in 2011 and 2016 and explore their possible health impacts. METHODS: This sequential explanatory mixed-method study was done in two stages of spatial analysis and qualitative study. Data mapping was conducted through the equal interval classification and using drought, migration, and agriculture occupation data based on provincial divisions in Iran in 2011 and 2016. This qualitative study was conducted using the content analysis approach. RESULTS: The in-migration rate was higher in 2011 rather than 2016. Migration to cities was much higher than migration to villages in both years. The frequency of male migrants was higher than females in all provinces in 2011 and 2016. Physical and mental diseases as well as economic, sociocultural, education, and environment effects on health were extracted from the qualitative data. CONCLUSION: A holistic picture of droughts and migration issues in Iran and their health consequences were achieved by the present research. Further research is needed to explore the determinants of health impacts of climate change in vulnerable groups. Public health problems can be prevented by adaptive and preventive policy-making and planning. This can improve the coping capacity of the population facing droughts and enforced migration.

Did the Affordable Care Act Promote Racial Equity in Pregnancy-Related Health? A Scoping Review.

In the United States, there are profound and persistent racial and ethnic disparities in pregnancy-related health, emphasizing the need to promote racial health equity through public policy. There is evidence that the Affordable Care Act (ACA) increased health insurance coverage, access to health care, and health care utilization, and may have affected some pregnancy-related health outcomes (eg, preterm delivery). It is unclear, however, whether these impacts on pregnancy-related outcomes were equitably distributed across race and ethnicity. Thus, the objective of this study was to fill that gap by summarizing the peer-reviewed evidence regarding the impact of the ACA on racial and ethnic disparities in pregnancy-related health outcomes. The authors conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR), using broad search terms to identify relevant peer-reviewed literature in PubMed, Web of Science, and EconLit. The authors identified and reviewed n = 21 studies and found that the current literature suggests that the ACA and its components were differentially associated with contraception-related and fertility-related outcomes by race/ethnicity. Literature regarding pregnancy health, birth outcomes, and postpartum health, however, was sparse and mixed, making it difficult to draw conclusions regarding the impact on racial/ethnic disparities in these outcomes. To inform future health policy that reduces racial disparities, additional work is needed to clarify the impacts of contemporary health policy, like the ACA, on racial disparities in pregnancy health, birth outcomes, and postpartum health.

Pigeonholes and Johari windows: Rehumanising ethnicity categorisation in health care.

CATEGORISATION CAN BRING CLARITY: Categorisation is just what we do in health care. It allows for definitions to be shared, so conditions can be targeted and treatments standardised. It allows for concepts and constructs to become testable objects of research. And, with the increasing push for diversity and inclusion, it allows for disparities to be identified to evidence progress and enable accountability. CATEGORISATION CAN ALSO CONFOUND: But could these distinctions be doing as much harm as good? In this article, I review work from the field of inclusive education, focusing particularly on "awarding gaps" and "differential attainment" (i.e. differences in the proportions of degrees with higher grades awarded to some groups of learners compared with others). In doing so, I draw attention to the paradox inherent in empirically studying these topics: increasing recognition of unfairness is dependent on categorising individuals into groups of students, which risks reinforcing negative, reductive associations and alienating those who cannot relate to their designation. CATEGORISATION REQUIRES CARE: Using the case of ethnicity categorisation (and mixed ethnicity categories in particular), I use this paper to explore this unwelcome impact of categorisation in more detail. I acknowledge how difficult it would be to overhaul our system of categorisation and finish with thoughts on how we might mitigate its impact in our practice.

The Association of Race, Ethnicity, and Insurance Status with the Visual Acuity of Retinoblastoma Survivors in the IRIS® Registry.

PURPOSE: To identify sociodemographic factors associated with the visual outcomes of retinoblastoma survivors. METHODS: Retrospective cohort study using a US-based clinical data registry. All individuals < 18 years of age with a history of retinoblastoma in the Intelligent Research in Sight (IRIS®) Registry (1/1/2013-12/31/2020). The primary outcome was visual acuity below the threshold for legal blindness (20/200 or worse) in at least one eye. Multivariable logistic regression was used to evaluate the association between visual outcomes and age, sex, laterality, race, ethnicity, type of insurance, and geographic location. RESULTS: This analysis included 1545 children with a history of retinoblastoma. The median length of follow-up was 4.1 years (IQR, 2.2-5.9 years) and the median age at most recent clinical visit was 12 years (IQR, 8-16 years). Retinoblastoma was unilateral in 54% of cases. Poor vision in at least one eye was identified in 78% of all children and poor vision in both eyes in 17% of those with bilateral disease. Poor visual outcomes were associated with unilateral diagnosis (OR, 1.55; 95% CI,1.13-2.12; p = .007), Black race (OR, 2.03; 95% CI, 1.19-3.47; p = .010), Hispanic ethnicity (OR, 1.65; 95% CI, 1.16-2.37; p = .006), and non-private insurance (OR, 1.47; 95% CI, 1.02-2.10; p = .037). CONCLUSIONS: Poor visual outcomes appear to be more common among Black, Hispanic, and publicly insured children with a history of retinoblastoma, raising concerns regarding healthcare inequities. Primary care physicians should ensure that young children receive red reflex testing during routine visits and consider retinoblastoma in the differential diagnosis of abnormal eye exams.

Racial Diversity of Patient Population Represented on United States Plastic Surgeons' Webpages.

ABSTRACT: Current literature demonstrates a lack of racial diversity in plastic surgery media. However, to our knowledge, no study has yet examined the racial diversity of Webpage content as if from a patient-search perspective. The objective of this study is to determine if there is a racial discrepancy between the US Census, American Society of Plastic Surgeons (ASPS) statistics, and the media featuring implied patients on US plastic surgeons' Webpages from a patient-focused approach. A Google search was completed using the term "(state) plastic surgeon." The first 10 relevant Web sites were collected for each state, and homepages were analyzed. In line with previous studies, the implied patients in media were classified into 1 of 6 skin tone categories: I, ivory; II, beige; III, light brown; IV, olive; V, brown; and VI, dark brown. These correlate to Fitzpatrick phototypes; however, the Fitzpatrick scale measures skin's response to UV exposure. Skin tone was used as a guide to measure racial representation in the media, with the caveat that skin tone does not absolutely correlate to racial identity. Categories I-III were further classified as "white" and IV-VI as "nonwhite." These data were compared with the 2020 ASPS demographics report and US Census. Four thousand eighty individuals were analyzed from 504 Webpages, the majority of which were those of private practice physicians. A total of 91.62% of individuals were classified as "white" and 8.38% "nonwhite." The distribution by category was as follows: I = 265, II = 847, III = 2626, IV = 266, V = 71, and VI = 5. Using χ2 analyses, a statistically significant difference was found between the racial representation within this sample and that of the 2020 US Census nationally (P < 0.001), regionally (P < 0.001), and subregionally (P < 0.001); the 2020 ASPS Cosmetic Summary Data (P < 0.001); and the 2020 ASPS Reconstructive Summary Data (P < 0.001). This study highlights the significant difference between racial representation on plastic surgeons' Webpages and the demographics of patients they serve. Further analyses should identify the impact of these representational disparities on patient care and clinical outcomes, as well as examine how best to measure racial diversity and disparities in patient-oriented media.

Hospice Knowledge, Attitudes, and Preference among Older Chinese Immigrants in the United States.

Racial disparities in hospice use are a longstanding concern in the U.S. Asian Americans are among the least likely to receive hospice care and to be included in studies on this topic. This study examined the knowledge, attitudes, and preferences related to hospice care among older Chinese immigrants and associated factors. A sample of 262 Chinese immigrants age 60+ was recruited from six older adult centers in NYC. In-person interviews were conducted in Mandarin and Cantonese. Non-English-speaking older Chinese immigrants had very limited knowledge about hospice care. Only 26% of respondents had heard of hospice, and a few could correctly define any components. After receiving a comprehensive definition of hospice care, study participants expressed a positive attitude and a strong willingness to use hospice if near the end of life. Notably, some respondents still held misconceptions about hospice and were less positive in their attitude and preference for hospice care. These findings underscore the necessity for clear and accessible information about hospice among this population throughout the trajectory from good health to end of life. Further research is needed to identify the range of factors that influence the attitudes and preferences of older Chinese immigrants toward hospice care.

Stigma salience increases loneliness among ethnic minorities.

Research shows that ethnic minorities are at increased risk of loneliness compared to the general population of the United Kingdom. We hypothesized that stigma salience increases loneliness among ethnic minorities, conducting two experimental studies with ethnic minorities (Study 1: N = 134, Study 2: N = 267) in which participants were randomly assigned to a stigma salience (recalling a personal experience of discrimination based on ethnicity) or control condition (recalling a past meal in Study 1 and the experience of reading a book in Study 2). Across these two studies, we demonstrated that stigma salience consistently increased self-reported loneliness relative to the control conditions. Study 1 additionally showed evidence for an indirect effect of stigma salience on loneliness through feelings of anxiety. Study 2 replicated the effect of self-relevant (but not non-self-relevant) stigma salience on loneliness and provided suggestive evidence for a more specific indirect effect through identity-related social anxiety.

Estimating migration timing and abundance in partial migratory systems by integrating continuous antenna detections with physical captures.

Many populations migrate between two different habitats (e.g. wintering/foraging to breeding area, mainstem-tributary, river-lake, river-ocean, river-side channel) as part of their life history. Detection technologies, such as passive integrated transponder (PIT) antennas or sonic receivers, can be placed at boundaries between habitats (e.g. near the confluence of rivers) to detect migratory movements of marked animals. Often, these detection systems have high detection probabilities and detect many individuals but are limited in their ability to make inferences about abundance because only marked individuals can be detected. Here, we introduce a mark-recapture modelling approach that uses detections from a double-array PIT antenna system to imply movement directionality from arrays and estimate migration timing. Additionally, when combined with physical captures, the model can be used to estimate abundances for both migratory and non-migratory groups and help quantify partial migration. We first test our approach using simulation, and results indicate our approach displayed negligible bias for total abundance (less than ±1%) and slight biases for state-specific abundance estimates (±1%-6%). We fit our model to array detections and physical captures of three native fishes (humpback chub [Gila cypha], flannelmouth sucker [Catostomus latipinnis] and bluehead sucker [Catostomus discobolus]) in the Little Colorado River (LCR) in Grand Canyon, AZ, a system that exhibits partial migration (i.e. includes residents and migrants). Abundance estimates from our model confirm that, for all three species, migratory individuals are much more numerous than residents. There was little difference in movement timing between 2021 (a year without preceding winter/spring floods) and 2022 (a year with a small flood occurring in early April). In both years, flannelmouth sucker arrived in mid-March whereas humpback chub and bluehead sucker arrivals occurred early- to mid-April. With humpback chub and flannelmouth sucker, movement timing was influenced by body size so that large individuals were more likely to arrive early compared to smaller individuals. With more years of data, this model framework could be used to evaluate ecological questions pertaining to flow cues and movement timing or intensity, relative trends in migrants versus residents and ecological drivers of skipped spawning.

Prevalence and Associations Between Metabolic Syndrome Components and Hyperuricemia by Race: Findings from US population, 2011 - 2020.

OBJECTIVE: We explored the trend in prevalence of hyperuricemia and metabolic syndrome in the US populations and investigated associations between components of metabolic syndrome and hyperuricemia by race. METHODS: We analyzed data from the four most recent NHANES cycles (2011 to March 2020), comprising 10,175 participants. Hyperuricemia is defined as serum urate > 7.0 mg/dL (men) or > 5.7 mg/dL (women), following the NHANES III guideline. Definition of metabolic syndrome follows National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) guideline. We estimated the prevalence of metabolic syndrome and hyperuricemia in each cycle and performed subgroup analyses with logistic regression to investigate the patterns of associated components of metabolic syndrome with hyperuricemia. RESULTS: In the most recent cycle (2017-March 2020), the prevalence of metabolic syndrome was 45.9% and that of hyperuricemia was 20.7%. Over the 2011-2020 period, a significant rise in metabolic syndrome prevalence was observed among Hispanic and Asian populations, and the prevalence of hyperuricemia has increased significantly only in Hispanic. After adjustment for confounding factors, subjects with metabolic syndrome exhibited a higher hyperuricemia in women than in men. Elevated BP was the strongest factor with hyperuricemia. The association was the weakest in Asian population. Waist circumference was the only significant factor associated with hyperuricemia in Asian. CONCLUSION: The prevalence of metabolic syndrome has increasing pattern, but there was no specific decadal trend in prevalence of hyperuricemia. There is an ethnic-specific association of metabolic syndrome and hyperuricemia, especially in Asian.

Racial Differences in Plasma Microbial Translocation and Plasma Microbiome, Implications in Systemic Lupus Erythematosus Disease Pathogenesis.

OBJECTIVE: Black groups have increased prevalence and accelerated pathogenicity of systemic lupus erythematosus (SLE) compared to other ethnic/racial groups. The microbiome and systemic microbial translocation are considered contributing factors to SLE disease pathogenesis. However, racial differences in the plasma microbiome and microbial translocation in lupus remain unknown. METHODS: In the current study, we investigated plasma levels of microbial translocation (lipopolysaccharide [LPS] and zonulin) and the plasma microbiome using microbial 16S RNA sequencing of Black and White patients with SLE and Black and White healthy controls. RESULTS: Plasma microbial translocation was increased in Black patients versus in White patients and in patients with SLE versus healthy controls regardless of race. Compared to sex, age, and disease status, race had the strongest association with plasma microbiome differences. Black groups (Black controls and Black patients) had lower α-diversity than White groups (White controls and White patients) and more distinct ß-diversity. Black and White patients demonstrated differences in plasma bacterial presence, including Staphylococcus and Burkholderia. Compared to White patients, Black patients had higher SLE Disease Activity Index (SLEDAI) scores and urinary protein levels as well as a trend for increased anti-double-stranded DNA (dsDNA) antibody levels consistent with the known increased severity of lupus in Black patients overall. Certain plasma bacteria at the genus level were identified that were associated with the SLEDAI score, urinary protein, and anti-dsDNA antibody levels. CONCLUSION: This study reveals racial differences in both quality and quantity of plasma microbial translocation and identified specific plasma microbiome differences associated with SLE disease pathogenesis. Thus, this study may provide new insights into future potential microbiome therapies on SLE pathogenesis.
