Ethnic Differences in the Rates of Posterior Capsule Rupture and Long-Term Sequelae in Phacoemulsification Cataract Surgery.

Purpose The purpose of this study is to investigate the rates of posterior capsular rupture (PCR) and its sequelae during phacoemulsification across different ethnicities. Methods This is a retrospective cohort study of all consecutive phacoemulsification cases complicated by PCR that met the inclusion criteria over a four-year period at a single tertiary eye centre in the United Kingdom (UK). Results PCR occurred in 0.85% of cases overall (157/18,481). PCR rates were 1.8% (26/1485), 1.2% (51/4350), and 0.7% (75/10,927) in African-Caribbean, Indian subcontinent, and Caucasian patients, respectively (p < 0.001). Mean final corrected distance visual acuity improved (p < 0.05) in all ethnic groups (0.40 ± 0.57 logMAR) compared to pre-op (0.78 ± 0.61 logMAR). Post-operative cystoid macular oedema and unstable intraocular pressure rates following PCR did not statistically differ amongst ethnicities (p = 0.37 and p = 0.75, respectively). However, post-operative uveitis rates significantly differed at 11.5%, 15.7%, and 1.3% amongst the three ethnic groups, respectively (p = 0.01). Conclusion This is the first study to highlight a possible link between patient ethnicity and the risk of PCR during phacoemulsification cataract surgery. We observed significantly greater numbers of PCR cases amongst certain ethnic groups (highest in African-Caribbean eyes, then Indian subcontinental eyes, and lowest in Caucasian eyes) within the same multi-cultural urban population. Ethnicity may therefore be a contributing factor for PCR and should potentially be taken into consideration during preoperative risk stratification.

Satisfaction following correction of spinal deformity: Cultural and regional effects on outcome.

Corrective spine surgery for spinal deformities, such as adolescent idiopathic scoliosis (AIS) and adult spinal deformity (ASD), aims to enhance the quality of life by addressing physical impairments. However, the extent of patient satisfaction after surgery, which includes pain management, functional recovery, and psychological contentment, exhibits considerable variation across different cultural and geographical landscapes. This review describes the influence of cultural and regional disparities on postoperative satisfaction in AIS and ASD surgery with a particular emphasis on the disparities between the US and Japan. This review underscores the intricate relationship between surgical outcomes and patient-reported satisfaction metrics. The investigation reveals significant contrasts in patient satisfaction and clinical results between these 2 countries, attributed to divergent cultural expectations, lifestyle adaptations, and perceptions of bodily image. These distinctions are crucial for healthcare professionals to recognize, as they necessitate a culturally nuanced approach to patient care. This comparative review not only enhances the understanding of patient experiences across cultures but also provides valuable guidance for physicians in customizing their strategies to align with the varied expectations of their patients, thereby improving postoperative satisfaction and overall quality of life. This review emphasizes the necessity of a tailored and culturally sensitive approach to managing spinal deformities, underscoring the need to factor in cultural and regional elements to enhance patient satisfaction and surgical outcomes.

Multiple Chronic Condition Emergency Department Visits Among U.S. Adults: Disparities at the Intersection of Intellectual and Developmental Disabilities Status and Race or Ethnicity.

Background: The study aims to examine the risk of multiple chronic condition (MCC)-related emergency department (ED) visits, MCC-related hospitalization following the ED visit, and mortality after MCC-related ED visits among adults with intellectual and developmental disabilities (IDD), adults compared with nondisabled adults by race and ethnicity, using the 2020 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample. Methods: We identified IDD adults using ICD-10-CM codes, extracting 296,394 nondisabled adults and 99,538 IDD adults, of which 67,771 are white, 19,164 are black, 10,667 are Latinx, and 1936 are other race or multiple race. The control group of nondisabled adults was age-matched and sex-matched in a 1:3 case-control ratio. We conducted multilevel Poisson regression models for the binary-dependent variables and adjusted for covariates, including sociodemographic and hospital characteristics. Results: The results show that across all racial/ethnic groups, individuals with IDD have significantly higher rates of MCC-related ED visits, hospitalizations, and deaths compared with nondisabled. Moreover, the disparities are more pronounced for individuals from racial/ethnic minority groups. Black and Latinx individuals with IDD have significantly higher rates of MCC-related ED visits and poor outcomes than their white counterparts with and without IDD. Conclusions: The findings from this study highlight significant racial and ethnic disparities in the risk of MCC-related ED visits, hospitalization following the ED visit, and mortality through the ED among IDD adults. This underscores the importance of adopting a multifaceted approach that addresses the social determinants of health, enhances access to health care, improves quality of care, and enhances care coordination.

Race, ethnicity, ancestry, and aspects that impact HLA data and matching for transplant.

Race, ethnicity, and ancestry are terms that are often misinterpreted and/or used interchangeably. There is lack of consensus in the scientific literature on the definition of these terms and insufficient guidelines on the proper classification, collection, and application of this data in the scientific community. However, defining groups for human populations is crucial for multiple healthcare applications and clinical research. Some examples impacted by population classification include HLA matching for stem-cell or solid organ transplant, identifying disease associations and/or adverse drug reactions, defining social determinants of health, understanding diverse representation in research studies, and identifying potential biases. This article describes aspects of race, ethnicity and ancestry information that impact the stem-cell or solid organ transplantation field with particular focus on HLA data collected from donors and recipients by donor registries or transplant centers.

Association between Metabolic Score for Visceral Fat and the risk of hypertension in different ethnic groups: a prospective cohort study in Southwest China.

Objective: Visceral adipose tissue assessment holds significant importance in hypertension prevention. This study aimed to explore the association between the Metabolic Score for Visceral Fat (METS-VF), a new indicator based on laboratory and anthropometry measures, and hypertension risk and to further investigate the association between the METS-VF and the risk of hypertension in different ethnic groups. Methods: In this study, a total of 9,280 people from 48 townships in 12 districts (counties) of Guizhou Province were selected for the survey using a multistage cluster random sampling method, and 5,127 cases were finally included in the analysis after excluding those with missing relevant data, losing visits, dying at follow-up, those who suffered from hypertension at baseline, and those whose information on the outcome of hypertension was not clear. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) between METS-VF and incident hypertension, and an accelerated failure time (AFT) model was applied to analyze the association between METS-VF and the onset time of hypertension. Results: The total person-years (PYs) of the 5,127 subjects were 36,188.52 years, and the median follow-up time was 6.64 years. During follow-up, 1,127 patients were newly diagnosed with hypertension, and the incidence density was 31.14/1,000 PYs. After adjusting for multivariables, compared with the METS-VF first (Q1), the third (Q3) and fourth (Q4) groups of the METS-VF increased by 29.9% and 61.5%, respectively (HR = 1.299 [1.061, 1.590] and 1.615 [1.280, 2.036]). The risk of hypertension increased with higher METS-VF values (HR = 1.323 [1.167, 1.500], ptrend < 0.001). In the Han Chinese population, Q2 and Q3 increased the risk of hypertension (HR = 1.459 [1.111, 1.917], 1.999 [1.417, 2.718]), and the onset of hypertension was advanced by 0.653 (ß = -0.653 (-0.930, -0.375]) years for per 1 unit increase in METS-VF. However, these associations were not found in ethnic minorities. Conclusion: METS-VF was significantly positively associated with the risk of hypertension, and the association was different among ethnic groups.

Diversity Plans and Postmarketing Studies: First Impressions of Anticipated Diversity Requirements in the United States.

INTRODUCTION: Recent Food and Drug Administration (FDA) draft guidelines are intended to improve representation and formalize the assessment of race and ethnicity in drug development, but how regulators and industry stakeholders plan to implement and enforce new requirements is still being determined. MATERIALS AND METHODS: Here, a 10-question survey was developed to assess the experiences of industry stakeholders in developing diversity plans. These survey results informed an analysis of postmarketing studies to understand how diversity requirements have been enforced to date. RESULTS AND DISCUSSION: Among 13 survey responders, experience submitting and receiving feedback on diversity plans was limited. A variety of challenges have been associated with developing these plans, including questions regarding regulatory guidance. Sponsors have utilized several data sources, including real-world datasets, to define enrollment goals. Diversity-related postmarketing studies most commonly related to oncologic diseases, and endpoints frequently related to efficacy. Most marketing applications associated with diversity-related postmarketing studies received Orphan drug designation (ODD) and Accelerated Approval. CONCLUSIONS: These results show that industry experience with diversity plans remains limited in the absence of finalized regulatory guidance. Sponsors are beginning to develop strategies for submitting diversity plans, which include identifying key functions and data sources to support enrollment goals, although definitive conclusions were difficult to draw from the small responder pool. In the postmarketing setting, studies are already underway to improve the understanding of racial and ethnic differences in responses to approved drugs. Development programs relating to oncology, which has historically suffered from a lack of diverse representation, have been a primary focus of such studies thus far.

Ethnicity Differences in Geometric Remodeling and Myocardial Composition in Hypertension unveiled by Cardiovascular Magnetic Resonance.

AIMS: Hypertensive patients of African-ancestry (Afr-a) have higher incidences of heart failure and worse clinical outcomes than hypertensive patients of European-ancestry (Eu-a), yet the underlying mechanisms remain misunderstood. This study investigated right (RV) and left (LV) ventricular remodeling alongside myocardial tissue derangements between Afr-a and Eu-a hypertensives. METHODS AND RESULTS: Sixty-three Afr-a and forty-seven Eu-a hypertensives underwent multi-parametric cardiovascular-magnetic-resonance. Biventricular volumes, mass, function, mass/end-diastolic volume (M/V) ratios, T2- and pre/post-contrast T1-relaxation-times, synthetic-extracellular-volume (s-ECV) and myocardial fibrosis (MF) were measured. Three-dimensional shape modeling was implemented to delineate ventricular geometry.LV and RV-mass (indexed to body-surface-area) and M/V ratios were significantly greater in Afr-a than Eu-a hypertensives (67.1±21.7 vs. 58.3±16.7g/m2, 12.6±3.48 vs. 10.7±2.71g/m2, 0.79±0.21 vs. 0.70±0.14g/ml, 0.16±0.04 vs. 0.13±0.03g/ml, respectively; P<0.03) mirroring LV remodeling. Afr-a patients showed greater basal-interventricular-septum thickness than Eu-a patients, which may influence LV hypertrophy and RV cavity changes. This biventricular remodeling was associated with prolonged T2-relaxation-time (47.0±2.2 vs. 45.7±2.2ms, P=0.005) and higher prevalence (23% vs. 4%, P=0.001) and extent of MF (2.3[0.6-14.3] vs. 1.6[0.9-2.5] % of LV-mass, P=0.008) in Afr-a patients. Multivariable linear regression showed modifiable cardiovascular risk-factors and greater end-diastolic volume were independently associated with greater LV or RV-mass. Furthermore, ethnicity was independently associated with greater RV-mass, supporting our hypothesis of ethnic-specific hypertensive remodeling. CONCLUSIONS: Afr-a hypertensives had distinctive biventricular remodeling, including increased RV-mass and septal thickening, and subtle myocardial tissue abnormalities compared to Eu-a hypertensives. From this study, modifiable cardiovascular risk-factors, and ventricular geometry, but not ethnicity, were independently associated with higher LV mass.

Ethnic differences in metabolic syndrome in high-income countries: A systematic review and meta-analysis.

This review aimed to systematically quantify the differences in Metabolic Syndrome (MetS) prevalence across various ethnic groups in high-income countries by sex, and to evaluate the overall prevalence trends from 1996 to 2022. We conducted a systematic literature review using MEDLINE, Web of Science Core Collection, CINAHL, and the Cochrane Library, focusing on studies about MetS prevalence among ethnic groups in high-income countries. We pooled 23 studies that used NCEP-ATP III criteria and included 147,756 healthy participants aged 18 and above. We calculated pooled prevalence estimates and 95% confidence intervals (CI) using both fixed-effect and random-effect intercept logistic regression models. Data were analysed for 3 periods: 1996-2005, 2006-2009, and 2010-2021. The pooled prevalence of MetS in high-income countries, based on the NCEP-ATP III criteria, was 27.4% over the studied period, showing an increase from 24.2% in 1996-2005 to 31.9% in 2010-2021, with men and women having similar rates. When stratified by ethnicity and sex, ethnic minority women experienced the highest prevalence at 31.7%, while ethnic majority women had the lowest at 22.7%. Notably, MetS was more prevalent in ethnic minority women than men. Among ethnic minorities, women had a higher prevalence of MetS than men, and the difference was highest in Asians (about 15 percentage points). Among women, the prevalence of MetS was highest in Asians (41.2%) and lowest in Blacks/Africans (26.7%). Among men, it was highest in indigenous minority groups (34.3%) and lowest among in Blacks/Africans (19.8%). MetS is increasing at an alarming rate in high-income countries, particularly among ethnic minority women. The burden of MetS could be effectively reduced by tailoring interventions according to ethnic variations and risk profiles.

Neurocognition and its predictors in a linguistically and culturally diverse cohort of people with HIV.

Objective: HIV/AIDS disproportionately affects Black and Latino people in the United States, yet there is a lack of research on predictors of neurocognitive outcomes in these groups. We examined neurocognitive performance and its key predictors across White, Black, and Latino people with HIV (PWH). Method: Participants included 586 PWH of White, Black, and Latino (English- and Spanish-speaking) background. Neurocognition was assessed via demographically-adjusted Fluid Cognition Composite T-scores from the NIH-Toolbox cognition battery, and individual tests comprising this composite. Predictors examined included sociodemographic and HIV disease characteristics, and medical, psychiatric and substance comorbidities. Results: Compared to White PWH, English-speaking Latino PWH had lower T-scores on the Fluid Cognition Composite, as well as Flanker Inhibition and Picture Sequence Memory tests. While there were no other significant group differences on Fluid Cognition, both Latino PWH language groups performed worse than Black PWH on Flanker Inhibition, and Black PWH performed worse than White PWH on List Sorting. Separate multivariable linear regression models by ethnic/racial/language group showed that significant correlates of worse Fluid Cognition included depressive symptoms among White PWH; hepatitis C co-infection among Black PWH; hypertension among English-speaking Latino PWH; and higher estimated duration of HIV disease and depressive symptoms in Spanish-speaking Latino PWH. Conclusions: Findings suggest worse neurocognition among English-speaking Latino PWH compared to Whites. Predictors of neurocognitive function among PWH differ across ethnic/racial and language groups. Consideration of these HIV disease characteristics and comorbidities may be valuable in developing targeted culturally-relevant interventions aimed at ameliorating neurocognitive dysfunction among diverse PWH.

The American Society for Bone and Mineral Research Task Force on clinical algorithms for fracture risk report.

Using race and ethnicity in clinical algorithms potentially contributes to health inequities. The American Society for Bone and Mineral Research (ASBMR) Professional Practice Committee convened the ASBMR Task Force on Clinical Algorithms for Fracture Risk to determine the impact of race and ethnicity adjustment in the US Fracture Risk Assessment Tool (US-FRAX). The Task Force engaged the University of Minnesota Evidence-based Practice Core to conduct a systematic review investigating the performance of US-FRAX for predicting incident fractures over 10 years in Asian, Black, Hispanic, and White individuals. Six studies from the Women's Health Initiative (WHI) and Study of Osteoporotic Fractures (SOF) were eligible; cohorts only included women and were predominantly White (WHI > 80% and SOF > 99%), data were not consistently stratified by race and ethnicity, and when stratified there were far fewer fractures in Black and Hispanic women vs White women rendering area under the curve (AUC) estimates less stable. In the younger WHI cohort (n = 64 739), US-FRAX without bone mineral density (BMD) had limited discrimination for major osteoporotic fracture (MOF) (AUC 0.53 (Black), 0.57 (Hispanic), and 0.57 (White)); somewhat better discrimination for hip fracture in White women only (AUC 0.54 (Black), 0.53 (Hispanic), and 0.66 (White)). In a subset of the older WHI cohort (n = 23 918), US-FRAX without BMD overestimated MOF. The Task Force concluded that there is little justification for estimating fracture risk while incorporating race and ethnicity adjustments and recommends that fracture prediction models not include race or ethnicity adjustment but instead be population-based and reflective of US demographics, and inclusive of key clinical, behavioral, and social determinants (where applicable). Research cohorts should be representative vis-à-vis race, ethnicity, gender, and age. There should be standardized collection of race and ethnicity; collection of social determinants of health to investigate impact on fracture risk; and measurement of fracture rates and BMD in cohorts inclusive of those historically underrepresented in osteoporosis research.

Using race or ethnicity when calculating disease risk may contribute to health disparities. The ASBMR Task Force on Clinical Algorithms for Fracture Risk was created to understand the impact of the US Fracture Risk Assessment Tool (US-FRAX) race and ethnicity adjustments. The Task Force reviewed the historical development of FRAX, including the assumptions underlying selection of race and ethnicity adjustment factors. Furthermore, a systematic review of literature was conducted, which revealed an overall paucity of data evaluating the performance of US-FRAX in racially and ethnically diverse groups. While acknowledging the existence of racial and ethnic differences in fracture epidemiology, the Task Force determined that currently there is limited evidence to support the use of race and ethnicity­specific adjustments in US-FRAX. The Task Force also concluded that research is needed to create generalizable fracture risk calculators broadly applicable to current US demographics, which do not include race and ethnicity adjustments. Until such population­based fracture calculators are available, clinicians should consider providing fracture risk ranges for Asian, Black, and/or Hispanic patients and should engage in shared decision-making with patients about fracture risk interpretation. Future studies are required to evaluate fracture risk tools in populations inclusive of those historically underrepresented in research.

The impact of cohort relationships on BIPOC genetic counseling students: Results from a longitudinal qualitative study.

The transition to graduate school is marked by stress, with academic demands and interpersonal interactions being primary concerns for genetic counseling students. For Black, Indigenous, and People of Color (BIPOC) graduate students, additional stressors caused by the "minority tax" and microaggressions impact their sense of belonging and inclusion. This prospective longitudinal study employed a constructivist grounded theory approach to investigate the experiences of first-year BIPOC genetic counseling students as they transitioned into the first year of their graduate training. We conducted semi-structured interviews with 26 first-year genetic counseling students at three key time points during their first year and analyzed them using reflexive thematic analysis. Here, we report themes related to stressors when transitioning into the genetic counseling training environment, the role of relationships as a source of support in navigating these challenges, and the impact of cohort dynamics on the training experience. Stressors included managing academic rigor and time demands, navigating microaggressions, reactions to discussions about diversity, equity, inclusion, and justice (DEIJ), and managing mental health. Peer relationships emerge as pivotal source of support, but challenging dynamics within the cohort negatively impacted participants, highlighting the importance of fostering an inclusive training environment. Since programs have less control over the composition of each cohort with the advent of the Match system in 2018, we recommend the use of community-building and debriefing activities to strengthen healthy relationships and address problematic dynamics. We recommend that training programs be proactive in creating mentoring relationships between faculty and students rather than waiting until students ask for help. Ultimately, we advocate for a holistic approach to genetic counseling training that maintains academic rigor but also prioritizes the creation of supportive, inclusive, and culturally sensitive learning environments for all students.

Disparities in Access to a Regular Primary Care Physician Among First-Generation Migrants with Early Psychosis in Ontario, Canada.

Disparities in primary care utilization among migrants with early psychosis may be related to lack of access to a regular primary care physician. This study aimed to investigate access to a regular primary care physician among first-generation migrants with early psychosis. People aged 14-35 years with first onset non-affective psychotic disorder in Ontario, Canada were identified in health administrative data (N = 39,440). Access to a regular primary care physician through enrollment in the year prior to diagnosis was compared between first-generation migrants (categorized by country of birth) and the general population using modified Poisson regression. Most migrant groups had a lower prevalence of regular primary care physician access relative to the general population, particularly migrants from Africa (African migrants: 81% vs. non-migrants: 89%). Adjustment for sociodemographic and clinical factors attenuated these differences, although the disparities for migrants from Africa remained (PR = 0.96, 95%CI = 0.94-0.99). Interventions aimed at improving primary care physician access in migrant groups may facilitate help-seeking and improve pathways to care in early psychosis.

Impact of maternal risk factors on ethnic disparities in maternal mortality: a national population-based cohort study.

Background: Ethnic disparities in maternal mortality are consistently reported. This study aimed to investigate the contribution of known risk factors including age, socioeconomic status, and medical comorbidities to observed ethnic disparities in the United Kingdom (UK). Methods: A cohort of all women who died during or up to six weeks after pregnancy in the UK 2009-2019 were identified through national surveillance. No single denominator population included data on all risk factors, therefore we used logistic regression modelling to compare to 1) routine population birth and demographic data (2015-19) (routine data comparator) and 2) combined control groups of four UK Obstetric Surveillance System studies (UKOSS) control comparator)). Findings: There were 801 maternal deaths in the UK between 2009 and 2019 (White: 70%, Asian: 13%, Black: 12%, Chinese/Other: 3%, Mixed: 2%). Using the routine data comparator (n = 3,519,931 maternities) to adjust for demographics, including social deprivation, women of Black ethnicity remained at significantly increased risk of maternal death compared with women of white ethnicity (adjusted OR 2.43 (95% Confidence Interval 1.92-3.08)). The risk was greatest in women of Caribbean ethnicity (aOR 3.55 (2.30-5.48)). Among women of White ethnicity, risk of mortality increased as deprivation increased, but women of Black ethnicity had greater risk irrespective of deprivation. Using the UKOSS control comparator (n = 2210), after multiple adjustments including smoking, body mass index, and comorbidities, women of Black and Asian ethnicity remained at increased risk (aOR 3.13 (2.21-4.43) and 1.57 (1.16-2.12) respectively). Interpretation: Known risk factors do not fully explain ethnic disparities in maternal mortality. The impact of socioeconomic deprivation appears to differ between ethnic groups. Funding: This research is funded by the National Institute for Health and Care Research (NIHR) Policy Research Programme, conducted through the Policy Research Unit in Maternal and Neonatal Health and Care, PR-PRU-127-21202.

Video interpretation in a medical spine clinic: A descriptive study of a diverse population and intervention.

OBJECTIVES: Back pain is one of the most challenging health conditions to manage. Healthcare providers face additional challenges when managing back pain for patients with culturally diverse backgrounds including addressing linguistic barriers and understanding patients' cultural beliefs about pain and healthcare. Knowledge about patients with culturally diverse backgrounds experiencing back pain and the interventions available to them is limited. Therefore, this study aims to describe the characteristics of patients with culturally diverse backgrounds experiencing back pain and the video interpretation intervention offered to them and further to explore the clinician's perspective on this intervention. METHODS: Data were collected from the electronic medical records and the Interpreter Gateway. Four clinicians participated in a group interview, where they described and evaluated the video interpretation intervention in detail inspired by the template for intervention description and replication (TIDieR) checklist and guide. RESULTS: A total of 119 (68%) patients accepted the intervention (53% women, mean 44 years). These patients represent 24 different languages, with 50% having at least one hospital-registered diagnosis and a mean number of five outpatient contacts, 1 year before receiving the intervention. Fifty-seven patients did not accept the intervention and declined interpretation or opted to use relatives or through video conferencing equipment. The intervention was positively evaluated by the clinicians. CONCLUSIONS: The detailed description of the population and the intervention together with the clinician perspective provides a valuable foundation for developing and refining similar interventions, allocating resources, and designing future research studies. The intervention consisted of a consultation lasting up to 2 h delivered by a rheumatologist and a physiotherapist, with a remote interpreter connected.

Racial/ethnic differences in the associations between trust in the U.S. healthcare system and willingness to test for and vaccinate against COVID-19.

BACKGROUND: Trust in the healthcare system may impact adherence to recommended healthcare practices, including willingness to test for and vaccinate against COVID-19. This study examined racial/ethnic differences in the associations between trust in the U.S. healthcare system and willingness to test for and vaccinate against COVID-19 during the first year of the pandemic. METHODS: This cross-sectional study used data from the REACH-US study, a nationally representative online survey conducted among a diverse sample of U.S. adults from January 26, 2021-March 3, 2021 (N = 5,121). Multivariable logistic regression estimated the associations between trust in the U.S. healthcare system (measured as "Always", "Most of the time", "Sometimes/Almost Never", and "Never") and willingness to test for COVID-19, and willingness to receive the COVID-19 vaccine. Racial/ethnic differences in these associations were examined using interaction terms and multigroup analyses. RESULTS: Always trusting the U.S. healthcare system was highest among Hispanic/Latino Spanish Language Preference (24.9%) and Asian (16.7%) adults and lowest among Multiracial (8.7%) and Black/African American (10.7%) adults. Always trusting the U.S. healthcare system, compared to never, was associated with greater willingness to test for COVID-19 (AOR: 3.20, 95% CI: 2.38-4.30) and greater willingness to receive the COVID-19 vaccine (AOR: 2.68, 95% CI: 1.97-3.65). CONCLUSIONS: Trust in the U.S. healthcare system was associated with greater willingness to test for COVID-19 and receive the COVID-19 vaccine, however, trust in the U.S. healthcare system was lower among most marginalized racial/ethnic groups. Efforts to establish a more equitable healthcare system that increases trust may encourage COVID-19 preventive behaviors.

The role of increasing synchronous telehealth use during the COVID-19 pandemic on disparities in access to healthcare: A systematic review.

INTRODUCTION: The COVID-19 public health emergency led to an unprecedented rapid increase in telehealth use, but the role of telehealth in reducing disparities in access to care has been questioned. The objective of this study was to conduct a systematic review to summarize the available evidence on how telehealth during the COVID-19 pandemic was associated with telehealth utilization for minority groups and its role in health disparities. METHODS: We conducted a systematic review focused on health equity and access to care by searching for interventional and observational studies using the following four search domains: telehealth, COVID-19, health equity, and access to care. We searched PubMed, Embase, Cochrane CENTRAL, CINAHL, telehealth.hhs.gov, and the Rural Health Research Gateway, and included any study that reported quantitative results with a control group. RESULTS: Our initial search yielded 1970 studies, and we included 48 in our final review. The most common dimensions of health equity studied were race/ethnicity, rurality, insurance status, language, and socioeconomic status, and the telehealth applications studied were diverse. Included studies had a moderate risk of bias. In aggregate, most studies reported increased telehealth use during the pandemic, with the greatest increase in non-minority populations, including White, younger, English-speaking people from urban areas. DISCUSSION: We found that despite rapid adoption and increased telehealth use during the public health emergency, telehealth did not reduce existing disparities in access to care. We recommend that future work measuring the impact of telehealth focus on equity so that features of telehealth innovation can reduce disparities in health outcomes.

Racial and ethnic differences in plasma biomarker eligibility for a preclinical Alzheimer's disease trial.

INTRODUCTION: In trials of amyloid-lowering drugs for Alzheimer's disease (AD), differential eligibility may contribute to under-inclusion of racial and ethnic underrepresented groups. We examined plasma amyloid beta 42/40 and positron emission tomography (PET) amyloid eligibility for the ongoing AHEAD Study preclinical AD program (NCT04468659). METHODS: Univariate logistic regression models were used to examine group differences in plasma and PET amyloid screening eligibility. RESULTS: Of 4905 participants screened at time of analysis, 1724 were plasma eligible to continue in screening: 13.3% Hispanic Black, 24.7% Hispanic White, 20.8% non-Hispanic (NH) Asian, 24.7% NH Black, and 38.9% NH White. Plasma eligibility differed across groups in models controlling for covariates (odds ratio from 1.9 to 4.0 compared to the NH White reference group, P < 0.001). Among plasma eligible participants, PET eligibility did not differ by group. DISCUSSION: These results suggest that prevalence of brain amyloid pathology differed, but that eligibility based on plasma was equally effective across racial and ethnic group members. HIGHLIGHTS: Plasma amyloid eligibility is lower in underrepresented racial and ethnic groups. In plasma eligible adults, positron emission tomography eligibility rates are similar across race and ethnicity. Plasma biomarker tests may be similarly effective across racial and ethnic groups.

Serum iron Profile of Patients with Sickle Cell Disease and its Association with Socio-demographic Characteristics and Duration of Diagnosis.

BACKGROUND: Sickle cell anemia is the most common hemoglobinopathy in the world. The study aimed to evaluate the iron profile and its association with socio-demographic characteristics in patients with sickle cell disease. METHODS: A hospital-based descriptive cross-sectional study was conducted to know the iron profile and its socio-demographic association in patients with sickle cell disease. RESULTS: The average serum iron, TIBC, and transferrin saturation were 16.75 ± 6.40 mcgMole/L, 69.46 ± 16.94 mcg/dl and 25.15 ± 12.51% respectively. The serum ferritin ranged from 10.00 to 3000.00 ng/ml. The proportion of participants with normal serum iron, TIBC, serum ferritin, and transferrin saturation were 86.10%, 0.00%, 33.90% and 36.40% respectively. All of the participants of this study had low TIBC (1005), and more than half of the participants had elevated serum ferritin (56.40%). CONCLUSIONS: Iron overload is a common complication of sickle cell disease. There was no association of age and sex with iron profile. The TIBC variation between the Chaudhary ethnic group compared to other ethnic groups signifies the ethnic role in the iron profile.

Environmental and sociocultural factors are associated with pain-related brain structure among diverse individuals with chronic musculoskeletal pain: intersectional considerations.

Chronic musculoskeletal pain including knee osteoarthritis (OA) is a leading cause of disability worldwide. Previous research indicates ethnic-race groups differ in the pain and functional limitations experienced with knee OA. However, when socioenvironmental factors are included in analyses, group differences in pain and function wane. Pain-related brain structures are another area where ethnic-race group differences have been observed. Environmental and sociocultural factors e.g., income, education, experiences of discrimination, and social support influence brain structures. We investigate if environmental and sociocultural factors reduce previously observed ethnic-race group differences in pain-related brain structures. Data were analyzed from 147 self-identified non-Hispanic black (NHB) and non-Hispanic white (NHW), middle and older aged adults with knee pain in the past month. Information collected included health and pain history, environmental and sociocultural resources, and brain imaging. The NHB adults were younger and reported lower income and education compared to their NHW peers. In hierarchical multiple regression models, sociocultural and environmental factors explained 6-37% of the variance in pain-related brain regions. Self-identified ethnicity-race provided an additional 4-13% of explanatory value in the amygdala, hippocampus, insula, bilateral primary somatosensory cortex, and thalamus. In the rostral/caudal anterior cingulate and dorsolateral prefrontal cortex, self-identified ethnicity-race was not a predictor after accounting for environmental, sociocultural, and demographic factors. Findings help to disentangle and identify some of the factors contributing to ethnic-race group disparities in pain-related brain structures. Numerous arrays of environmental and sociocultural factors remain to be investigated. Further, the differing sociodemographic representation of our NHB and NHW participants highlights the role for intersectional considerations in future research.
