Aim: Tacrolimus, an immunosuppressant used to prevent organ rejection in renal transplant patients, exhibits high inter-patient variability, necessitating therapeutic drug monitoring. Early post-transplant tacrolimus exposure in Hispanics is understudied. Although genotypic information is linked to pharmacokinetic differences, its clinical application remains limited. This study aimed to use a real-world data-driven, pharmacokinetic model-based approach for tacrolimus in Hispanics to determine a suitable initial dose and design an optimal dose titration strategy by simulations to achieve plasma trough concentration target levels of 10-12 ng/mL at the earliest. Methods: Sparse concentration-time data of tacrolimus were obtained from electronic medical records for self-identified Hispanic subjects following renal transplant. Rich pharmacokinetic literature data was leveraged to estimate structural pharmacokinetic model parameters, which were then fixed in the current analysis. Only apparent clearance was estimated with the sparse tacrolimus data and potential covariates were identified. Simulations of various starting doses and different dose titration strategies were then evaluated. Results: The analysis included 121 renal transplant patients with 2,215 trough tacrolimus concentrations. A two-compartment transit absorption model with allometrically scaled body weight and time-varying hematocrit on apparent clearance adequately described the data. The estimated apparent clearance was 13.7 L/h for a typical patientweighing 70 kg and at 30%hematocrit, demonstrating a 40% decrease in clearance compared to other patient populations. Model based simulations indicated the best initial dose for the Hispanic population is 0.1mg/kg/day. The proposed titration strategy, with three dose adjustments based on trough levels of tacrolimus, increased the proportion of patients within the target range (10-12 ng/mL) more than 2.5-fold and decreased the proportion of patients outside the therapeutic window by 50% after the first week of treatment. Conclusion: Hispanic renal transplant population showed an estimated 40% decrease of apparent clearance in the typical patient compared to other populations with similar characteristics. The proposed dose adjustment attained the target range rapidly and safely. This study advocates for tailored tacrolimus dosing regimens based on population pharmacokinetics to optimize therapy in Hispanic renal transplant recipients. [ABSTRACT FROM AUTHOR]

The USDA Thrifty Food Plan (TFP) is a federal estimate of a healthy diet at lowest cost for US population groups defined by gender and age. The present goal was to develop a version of the TFP that was more tailored to the observed dietary patterns of self-identified Hispanic participants in NHANES 2013–16. Analyses used the same national food prices and nutrient composition data as the TFP 2021. Diet quality was measured using the Healthy Eating Index 2015. The new Hispanic TFP (H-TFP) was cost-neutral with respect to TFP 2021 and fixed at $186/week for a family of four. Two H-TFP models were created using a quadratic programming (QP) algorithm. Fresh pork was modeled separately from other red meats. Hispanic NHANES participants were younger, had lower education and incomes, but had similar or higher HEI 2015 scores than non-Hispanics. Their diet included more pulses, beans, fruit, 100% juice, grain-based dishes, and soups, but less pizza, coffee, candy, and desserts. The H-TFP market basket featured more pork, whole grains, 100% fruit juice, and cheese. The second TFP model showed that pork could replace both poultry and red meat, while satisfying all nutrient needs. A vegetarian H-TFP proved infeasible for most age–gender groups. Healthy, affordable, and culturally relevant food plans can be developed for US population subgroups. [ABSTRACT FROM AUTHOR]

Among the many social determinants linked to adolescent alcohol use and depression, racial and ethnic discrimination is a prevalent determinant among Latinx adolescents and adults that is largely overlooked in preventive interventions. This study explored the influence of perceived racial and ethnic discrimination on depressive symptoms and alcohol use intentions among Latinx adolescents. Additionally, the study explored the cross-generational effects of how mothers' perceived discrimination impacts the depressive symptoms and alcohol use of the adolescent. The study used a sample of 800 inner-city Dominican and Puerto Rican adolescent–mother dyads (adolescent mean age = 12.42 years, SD = 0.81; mother mean age = 40.55 years, SD = 8.70). Employing a five-wave panel design that followed adolescents from 8th grade to 10th grade, the study found statistically significant mediation pathways which showed that adolescents' self-reported racial and ethnic discrimination experiences were associated with increases in their immediate and long-term depressive symptoms, which in turn were associated with stronger intentions to use alcohol in the future. Further, perceived racial and ethnic discrimination experienced by Latinx mothers was associated with increases in adolescents' intentions to drink alcohol in the future, mediated by the mothers' depressive symptoms and subsequently the adolescents' depressive symptoms. As discussed, these findings have wide-ranging implications for alcohol use prevention programs targeting inner-city Latinx adolescents. [ABSTRACT FROM AUTHOR]

Serendipity, curiosity, and lived experience shaped my career as a social demographer and my interests in social policy. I transitioned from the humanities to sociology and demography as a graduate student at the University of Texas at Austin, where I discovered my affinity for quantitative research. My interest in Latin American demography gave way to domestic concerns as new opportunities arose at each of the three institutions where I have had the privilege to work—the University of Wisconsin-Madison, the University of Chicago, and Princeton University. That all three institutions hosted vibrant demography and policy programs facilitated my research about the Hispanic population, family structure, urban poverty, college access, and myriad aspects of socioeconomic inequality and immigrant integration. Superb colleagues and talented graduate student collaborators deserve major credit for my career accomplishments. I attribute numerous opportunities to serve on philanthropic and corporate boards to the strength of weak ties. [ABSTRACT FROM AUTHOR]

As the U.S Hispanic population has increasingly grown throughout the years, the growing population has indicated that there will be change in the makeup of the cultural fabric of the country. The Hispanic population growth has led to the increase in numbers of English Learner (EL) students in both private and public schools in the U.S. which has subsequently led to the need to adapt and improve the U.S. education system for EL students. As the transformation in our counties cultural fabric continues to change the same change needs to be reflected on the student's education. This narrative will explain and rationalize the pedagogical practices that are in place to improve and embrace multilingualism and multiculturalism in education from early childhood development to higher education. The narrative found that a key indicator that influences the success of Hispanic students is early childhood development and education, this includes having access to necessary resources, being in culturally stimulating environment and training in English proficiency. The narrative also found that early education should not be limited to just schools but also needs the cooperation from the student's family and cultural centers. If early childhood development is not established the student will not be on the same level as other students and will be attempting to catch up to the education level other students are at. As the student gets older practices such as the ones being practiced in early childhood development should expand throughout the student's education. [ABSTRACT FROM AUTHOR]

Low health literacy (LHL) significantly impacts patients' ability to participate actively in their healthcare. Registered nurses (RNs) play a crucial role in identifying LHL and addressing patient knowledge gaps and skill deficits. This correlational study examined the relationship between RNs' predictions of patients' health literacy levels (HLL) and the actual HLL of a predominately Hispanic patient population. In addition, personal factors (i.e., demographics) were analyzed to determine their influence on the nurse's predictions and patients' HLL. Data were collected from 84 participant patient–nurse couplets admitted to a medical-surgical unit in a rural setting located on the United States–Mexico border. In addition to demographic information collected via survey, RNs were asked to predict their patient's health literacy abilities while the Newest Vital Sign, a health literacy assessment tool, was deployed to determine the actual HLL of patients participating in the study. Data were analyzed using descriptive statistics, t -tests, and chi-square tests while a Spearman correlational model was used to examine the relationship between predicted HLL and actual HLL. Finally, a logistic regression model was used to analyze the relationship between personal factors and HL data for RNs and patients. Analysis of the data revealed that RNs consistently overestimated patients' abilities, as evidenced by the disparity between patients' actual HLL (mean 1.71) and predicted HLL (mean 4.26) by RNs, with a moderately strong positive relationship (rs =.418). Notably, higher academic preparation and years of experience did not enhance the RNs' ability to identify LHL while the highest level of education completed was the only statistically significant predictor of adequate health literacy in the patient population sampled. These findings emphasize the need to prioritize effective health literacy education in RN academic preparation and clinical practice to support the detection of LHL when a standardized health literacy assessment tool is not utilized in the clinical setting. By recognizing the presence of LHL, healthcare professionals can better support patients' needs and bridge the knowledge gap, ultimately improving patient outcomes. [ABSTRACT FROM AUTHOR]

There are three major microvascular complications of diabetes, retinopathy, nephropathy, and neuropathy, among which diabetic retinopathy (DR) is the most common. Several studies suggest that the Hispanic/LatinX population exhibit the highest cases of both diabetes and DR. Strategies aimed at reducing risk factors that could minimize the likelihood of DR development or progression could be beneficial. This retrospective study assessed DR in the Hispanic/LatinX population in pharmacist-managed cardiovascular risk reduction services. A chart review was conducted for 60 individuals who visited clinics led by both a pharmacist and a primary care physician (intervention group) and 178 individuals who saw physicians only (control group). Demographics, metabolic parameters, DR severity, and pharmacist appointment data were collected. The highest benefit of pharmacist intervention was observed in terms of a greater but insignificant decrease in HbA1c; however, there was no benefit of pharmacist's intervention on DR in general, likely due to the longer duration of diabetes and higher HbA1c at the beginning of the study. When the DR progression was examined based on the frequency of pharmacy visits, individuals who met a pharmacist more than two times per year showed more stable and lesser worsening of DR. Overall, our studies suggest that pharmacist intervention could benefit retinopathy outcome; however, well-known determinants of DR such as good glycemic control and duration of diabetes still play a critical role, in addition to challenges in receiving healthcare by the Hispanic/LatinX population. Future strategies in a prospective manner could help retinopathy outcomes in these at-risk patient populations. [ABSTRACT FROM AUTHOR]

Hispanics in the USA, particularly those of Caribbean descent, experience high levels of diet-related diseases and dietary risk factors. Restaurants are an increasingly important yet understudied source of food and may present opportunities to positively influence urban food environments. We sought to explore food environments further, by examining the association between neighborhood characteristics and restaurant consumer nutrition environments within New York City's Hispanic Caribbean (HC) restaurant environments. We applied an adapted version of the Nutrition Environment Measurements Survey for Restaurants (NEMS-R) to evaluate a random sample of HC restaurants (n=89). NEMS-HCR scores (continuous and categorized as low, medium, and high based on data distribution) were examined against area sociodemographic characteristics using bivariate and logistic regression analysis. HC restaurants located in Hispanic geographic enclaves had a higher proportion of fried menu items (p6), compared with their medium (aOR: 6.6, 95% CI: 1.8-24.6) and large counterparts (aOR: 5.6, 95% CI: 1.5-21.4). This research is the first to examine the association between restaurant location and consumer nutrition environments, providing information to contribute to future interventions and policies seeking to improve urban food environments in communities disproportionately affected by diet-related conditions, as in the case of HC communities in New York City.

BackgroundObesity and related comorbidities are major health concerns among many US immigrant populations. Emerging evidence suggests a potential involvement of the gut microbiome. Here, we evaluated gut microbiome features and their associations with immigration, dietary intake, and obesity in 2640 individuals from a population-based study of US Hispanics/Latinos.ResultsThe fecal shotgun metagenomics data indicate that greater US exposure is associated with reduced ɑ-diversity, reduced functions of fiber degradation, and alterations in individual taxa, potentially related to a westernized diet. However, a majority of gut bacterial genera show paradoxical associations, being reduced with US exposure and increased with fiber intake, but increased with obesity. The observed paradoxical associations are not explained by host characteristics or variation in bacterial species but might be related to potential microbial co-occurrence, as seen by positive correlations among Roseburia, Prevotella, Dorea, and Coprococcus. In the conditional analysis with mutual adjustment, including all genera associated with both obesity and US exposure in the same model, the positive associations of Roseburia and Prevotella with obesity did not persist, suggesting that their positive associations with obesity might be due to their co-occurrence and correlations with obesity-related taxa, such as Dorea and Coprococcus.ConclusionsAmong US Hispanics/Latinos, US exposure is associated with unfavorable gut microbiome profiles for obesity risk, potentially related to westernized diet during acculturation. Microbial co-occurrence could be an important factor to consider in future studies relating individual gut microbiome taxa to environmental factors and host health and disease.

Abstract Introduction: Latinx populations are underrepresented in clinical research. Asking Latinx research participants about their research experiences, barriers, and facilitators could help to improve research participation for these populations. Methods: The Salud Estres y Resilencia (SER) Hispano cohort study is a longitudinal cohort study of young adult Latinx immigrants whose design and conduct were tailored for their study population. We administered the Research Participant Perception Survey (RPPS) to SER Hispano participants to assess their experiences in the study. We describe overall results from the RPPS and compare results of surveys administered to SER Hispano participants via email versus telephone. Results: Of 340 participants who were contacted with the RPPS, 142 (42%) responded. Among respondents, 53 (37%) responded by initial email contact; and 89 (63%) responded by subsequent phone contact. The majority of respondents were between 35 and 44 years of age (54%), female (76%), and of Cuban origin (50%). Overall, research participants expressed high satisfaction with their research experience; 84% stated that they would “definitely” recommend research participation to friends and family, with no significant difference by method of survey administration (P = 0.45). The most common factor that was chosen that would influence future research participation was having summary results of the research shared with them (72%). Conclusion: We found that culturally tailored studies can be good experiences for Latinx research participants; and we found that use of the RPPS can be administered successfully, particularly when administered by more than one method, including telephone, to evaluate and to improve research experiences for this population.

BackgroundGastric signet ring cell carcinoma (GSRC) is a rare but increasingly prevalent tumor histotype whose clinical features and natural history are poorly understood, particularly in the USA and minorities.AimsTo examine the occurrence, clinico-demographic characteristics, oncologic features, treatment, and outcomes of GSRC in a predominantly minority county hospital setting and benchmark them against data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program.MethodsWe queried biopsy-proven GSRC cases at a Los Angeles County hospital, from 2004 to 2017. Clinical characteristics, treatment, and survival data were collected and compared to SEER data.ResultsWe identified 63 patients with GSRC. Compared to SEER, our cohort was significantly younger (52.6 vs. 63.5 years, p

Alzheimer's disease (AD), a main cause of dementia, is commonly seen in aging populations with a strong genetic component. AD is one of the most common neurodegenerative disorders; it is a genetically and clinically heterogeneous disease. Specific demographic factors and genetic variants have been identified in non-Hispanic populations; however, limited studies have observed the Hispanic population. Therefore, we focused on investigating a known gene, APOE, associated with AD-related phenotypes and two psychiatric diseases (depression and anxiety) within the U.S. Hispanic population in our current study. A total of 1382 subjects were studied based on data collected from the Texas Alzheimer's Research and Care Consortium (TARCC, N = 1320) and the Initial Study of Longevity and Dementia from the Rio Grande Valley (ISLD-RGV, N = 62). Questionnaires regarding demographics, medical history, and blood/saliva samples were collected. We genotyped the APOE gene. The current findings indicated that APOE-ε4 was associated with not only AD (p < 0.0001) but also with anxiety (p < 0.0001) and depression (p = 0.0004). However, APOE-ε3 was associated with depression (p = 0.002) in the Hispanic population. We provide additional evidence in which APOE-ε4 increased the risk for AD in Hispanics. For the first time, APOE alleles show increased risks for anxiety and depression in Hispanics. Further research is warranted to confirm the current findings. [ABSTRACT FROM AUTHOR]

Abstract Background The human genome presents variation at distinct levels, copy number variants (CNVs) are DNA segments of variable lengths that range from several base pairs to megabases and are present at a variable number of copies in human genomes. Common CNVs have no apparent influence on the phenotype; however, some rare CNVs have been associated with phenotypic traits, depending on their size and gene content. CNVs are detected by microarrays of different densities and are generally visualized, and their frequencies analysed using the HapMap as default reference population. Nevertheless, this default reference is inadequate when the samples analysed are from people from Mexico, since population with a Hispanic genetic background are minimally represented. In this work, we describe the variation in the frequencies of four common CNVs in Mexican-Mestizo individuals. Results In a cohort of 147 unrelated Mexican-Mestizo individuals, we found that the common CNVs 2p11.2 (99.6%), 8p11.22 (54.5%), 14q32.33 (100%), and 15q11.2 (71.1%) appeared with unexpectedly high frequencies when contrasted with the HapMap reference (ChAS). Yet, while when comparing to an ethnically related reference population, these differences were significantly reduced or even disappeared. Conclusion The findings in this work contribute to (1) a better description of the CNVs characteristics of the Mexican Mestizo population and enhance the knowledge of genome variation in different ethnic groups. (2) emphasize the importance of contrasting CNVs identified in studied individuals against a reference group that—as best as possible—share the same ethnicity while keeping this relevant information in mind when conducting CNV studies at the population or clinical level.

BackgroundHispanics living in the USA may have unrecognized potential birthplace and lifestyle influences on the gut microbiome. We report a cross-sectional analysis of 1674 participants from four centers of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), aged 18 to 74 years old at recruitment.ResultsAmplicon sequencing of 16S rRNA gene V4 and fungal ITS1 fragments from self-collected stool samples indicate that the host microbiome is determined by sociodemographic and migration-related variables. Those who relocate from Latin America to the USA at an early age have reductions in Prevotella to Bacteroides ratios that persist across the life course. Shannon index of alpha diversity in fungi and bacteria is low in those who relocate to the USA in early life. In contrast, those who relocate to the USA during adulthood, over 45 years old, have high bacterial and fungal diversity and high Prevotella to Bacteroides ratios, compared to USA-born and childhood arrivals. Low bacterial diversity is associated in turn with obesity. Contrasting with prior studies, our study of the Latino population shows increasing Prevotella to Bacteroides ratio with greater obesity. Taxa within Acidaminococcus, Megasphaera, Ruminococcaceae, Coriobacteriaceae, Clostridiales, Christensenellaceae, YS2 (Cyanobacteria), and Victivallaceae are significantly associated with both obesity and earlier exposure to the USA, while Oscillospira and Anaerotruncus show paradoxical associations with both obesity and late-life introduction to the USA.ConclusionsOur analysis of the gut microbiome of Latinos demonstrates unique features that might be responsible for health disparities affecting Hispanics living in the USA.

(1) Background: Due to their high nutritional value, we aimed to characterize the frequency and amount of maternal consumption of beans during pregnancy and their associations with diet quality and nutrient intake. (2) Methods: We conducted a secondary data analysis of US pregnant women (n = 1444) from the Infant Feeding Practices Study II, a longitudinal study that followed mother–infant pairs from late pregnancy to 1 year postpartum. Maternal bean intake (food types [dried beans, chili, and bean soup], frequency, serving size, and amount), diet quality (Healthy Eating Index [HEI]), and nutrient intake were estimated with a Food Frequency Questionnaire taken in the third trimester of pregnancy. Associations of bean consumption with diet quality and nutrient intake were examined with analysis of variance, Fisher's least significant difference tests, correlation coefficients, and coefficients of determination. (3) Results: In general, maternal bean consumption was low during pregnancy: 0.31 cups/week of dried beans, 0.37 cups/week of chili, and 0.10 cups/week of bean soup. Maternal bean consumption varied by socio-demographics and geographic regions. In comparison with those who never consumed dried beans, mothers who ate dried beans ≥ 1 time per week had a higher mean HEI score (67.5 vs. 63.6), intake of total fiber (24.4 vs. 17.4 g/day), and protein (93.4 vs. 79.9 g/day), but a lower percentage of energy from added sugar (12.6 vs. 15.2%). Higher dried bean consumption had weak-to-moderate correlations with intake of total fiber (correlation coefficient, 0.320), insoluble fiber (0.316), soluble fiber (0.310), and folate (0.286). Similar but less extensive correlations were observed for chili and bean soup consumption. (4) Conclusions: In this US cohort of pregnant women, bean consumption was low. Increased intake of beans (≥1 time per week) may improve maternal diet quality during pregnancy. [ABSTRACT FROM AUTHOR]

The Internet is a major source of patient information on medical subjects. Several studies have evaluated the content of English medical material for patient use. However, few have focused on evaluating other languages, an important gap in a growing Spanish-speaking population. The aim of this study is to evaluate and compare English and Spanish online content related to pancreatic cancer treatment. We conducted a Google web search in English and Spanish using the following terms "pancreatic cancer treatment" and "tratamiento cancer de pancreas." The first 15 educational patient-directed websites for each language were included. Two independent reviewers assessed materials for quality and understandability using the DISCERN and the Patient Education Materials Assessment Tool (PEMAT)–validated tools. Readability was measured using two standardized tests. Wilcoxon rank sum test and unpaired Student's T-test were used for comparisons. Overall, websites in Spanish and English were understandable and had moderate to high quality. There were no significant differences in quality (p = 0.712) and understandability (p = 0.069) between languages. Readability level was significantly higher in English (p < 0.001) with content being at the university level, while Spanish was at the 12th grade level. Patient-directed online content on pancreatic cancer treatments exceeds the recommended reading level in both languages. Material is understandable with reasonable quality. Health content creators should acknowledge readability for information to be easily comprehended by those with lower health literacy. [ABSTRACT FROM AUTHOR]

Background Hispanic populations are more likely to develop diabetes and its related diseases than non‐Hispanic White populations. Little evidence exists to support whether the cardiovascular and renal benefits of sodium‐glucose cotransporter 2 inhibitors and glucagon‐like peptide‐1 receptor agonists are generalizable to the Hispanic populations. Methods and Results We included the cardiovascular and renal outcome trials (up to March 2021) that reported the major adverse cardiovascular events (MACEs), cardiovascular death/hospitalization for heart failure, and composite renal outcomes by ethnicity in individuals with type 2 diabetes (T2D), calculated pooled hazard ratios (HRs) with 95% CIs using fixed‐effects models, and tested the differences between Hispanic and non‐Hispanic populations (P for interaction [Pinteraction]). In 3 sodium‐glucose cotransporter 2 inhibitor trials, there was a statistically significant difference between Hispanic (HR, 0.70 [95% CI, 0.54–0.91]) and non‐Hispanic (HR, 0.96 [95% CI, 0.86–1.07]) groups in treatment effects on MACE risk (Pinteraction=0.03), except for risks of cardiovascular death/hospitalization for heart failure (Pinteraction=0.46) and composite renal outcome (Pinteraction=0.31). In 5 glucagon‐like peptide‐1 receptor agonist trials, there was no statistically significant difference in treatment effect on MACE risk between Hispanic (HR, 0.82 [95% CI, 0.70–0.96]) and non‐Hispanic (HR, 0.92 [95% CI, 0.84–1.00]) populations (Pinteraction=0.22). In 3 dipeptidyl peptidase‐4 inhibitor trials, the HR for MACE risk appeared greater in Hispanic (HR, 1.15 [95% CI, 0.98–1.35]) than non‐Hispanic (HR, 0.96 [95% CI, 0.88–1.04]) populations (Pinteraction=0.045). Conclusions Compared with non‐Hispanic individuals, Hispanic individuals with T2D appeared to obtain a greater benefit of lowered MACE risk with sodium‐glucose cotransporter 2 inhibitors.

Abstract Pulmonary arterial hypertension (PAH) is a cardiovascular disease with high mortality rate. Current guidelines propose initiation and escalation of PAH‐targeted treatment based on a goal‐directed approach targeting hemodynamic, functional, and biochemical variables. This approach has been successfully validated in large Caucasian cohorts. However, given the low number of Hispanic patients enrolled in large PAH trials and registries, it is unknown if the same prognostic tools can be applied to this patient population. We analyzed a single‐center outpatient cohort that consisted of 135 Hispanic patients diagnosed with PAH. Baseline characteristics were calculated based on COMPERA, COMPERA 2.0 and REVEAL 2.0 risk scores before the initiation of PAH‐targeted therapies. The survival rate at 1 year after diagnosis was 88% for the entire cohort. The three established risk scores to predict PAH outcomes yielded similar results with reasonable discrimination of mortality in the different risk strata (all p

Results: In a cohort of 147 unrelated Mexican-Mestizo individuals, we found that the common CNVs 2p11.2 (99.6%), 8p11.22 (54.5%), 14q32.33 (100%), and 15q11.2 (71.1%) appeared with unexpectedly high frequencies when contrasted with the HapMap reference (ChAS). Yet, while when comparing to an ethnically related reference population, these differences were significantly reduced or even disappeared. Conclusion: The findings in this work contribute to (1) a better description of the CNVs characteristics of the Mexican Mestizo population and enhance the knowledge of genome variation in different ethnic groups. (2) emphasize the importance of contrasting CNVs identified in studied individuals against a reference group that—as best as possible—share the same ethnicity while keeping this relevant information in mind when conducting CNV studies at the population or clinical level.

Reflex human papilloma virus (HPV) testing with "atypical squamous cells, cannot exclude high-grade squamous lesion (ASC-H)" cytologic diagnosis is not recommended by American Society for Colposcopy and Cervical Pathology guidelines. Studies have shown human papillomavirus (HPV)-negative ASC-H patients of increased age are low risk for cervical intraepithelial neoplasia 2 or worse (CIN2+) lesions on colposcopic follow-up. We retrospectively assessed the efficacy of reflex HPV testing in postmenopausal women with ASC-H in the Los Angeles County hospitals and clinics in a 5-year period. Of a total 85 clinically postmenopausal women with ASC-H, 31 (36.5%) women were found to have CIN2+ lesions on follow-up biopsy and five of them were HPV-negative. Of the women with CIN2+ lesions and positive HPV, 13 (41.9%) were high-risk HPV (hrHPV) 16/18/45 positive and 13 (41.9%) were hrHPV-other subtype positive. Women with positive HPV had an over 3-fold increased risk of developing CIN2+ lesions (P = 0.008). Relative risk of hrHPV16/18/45 was 1.79-fold higher than that of hrHPV-other subtype. The positive predictive value and negative predictive value of hrHPV were 49.1% and 84.4%, respectively. CIN2+ detection rate in Hispanic women with positive hrHPV was higher than in non-Hispanic women (53.8% versus 35.7%). Overall, postmenopausal women with ASC-H cytology result and negative hrHPV were less likely to develop CIN2+ lesions, whereas about half of ASC-H postmenopausal women develop CIN2+ lesions if hrHPV positive, especially if hrHPV 16/18/45 positive. Therefore, triaging ASC-H postmenopausal women with cotesting or, ideally, hrHPV genotyping should be considered as optimal clinical practice to avoid overtreatment. • The participants in our study are Los Angeles (LA) County patients who are predominantly Hispanic women and for whom routine cervical cancer screening program is sometimes difficult to be implemented. • The LA county system is considering to human papillomavirus (HPV) testing as primary for cervical cancer screening, however, from the results of our study that negative HPV testing misses small groups of high-grade cervical lesions, cotesting would be an optimal and safe practice to avoid overtreatment, especially for postmenopausal women.

Thus, our study explores this novel connection in Texas border hospitals using a non-experimental longitudinal study design.Materials and Methods: Using longitudinal panel data (2013∼ 2016) drawn from the American Hospital Association Annual Survey Database, Hospital Compare, and Area Health Resource File, a random-effects linear regression analysis was performed to quantify the impact of border location on the readmission rates of the same sample at multiple timed points.Results: We found a positive relationship between border location and 30-day hospital readmission rates for heart failure and pneumonia in Texas. Border hospitals in Texas had approximately a 4.17% higher heart failure readmission rate and a 3.46% higher pneumonia readmission rate than non-border hospitals. We also identified several hospital organizational and market factors associated (eg, registered nurse [RN]-to-patient ratio) with hospital readmission rates.Conclusion: The results suggest that improving RN staffing levels can be the most feasible action to lower the readmission rates among border Texas hospitals. Decreasing readmission rates by increasing RN staffing levels would also help them avoid reimbursement reduction under the Hospital Readmission Reduction Program (HRRP) and enhance overall health in Texas border communities. Further, to improve border health in Texas, decision-makers in state and local governments must consider incentivizing border hospitals to improve RN staffing levels and modulating the market factors affecting hospital readmission rates that are mostly beyond the control of hospitals.Keywords: U.S.-Mexico border, hospital, quality of care, readmission, registered nurse, nurse staffing, hospital characteristics, Hispanic population, county, market factors

Abstract Background Obesity and related comorbidities are major health concerns among many US immigrant populations. Emerging evidence suggests a potential involvement of the gut microbiome. Here, we evaluated gut microbiome features and their associations with immigration, dietary intake, and obesity in 2640 individuals from a population-based study of US Hispanics/Latinos. Results The fecal shotgun metagenomics data indicate that greater US exposure is associated with reduced ɑ-diversity, reduced functions of fiber degradation, and alterations in individual taxa, potentially related to a westernized diet. However, a majority of gut bacterial genera show paradoxical associations, being reduced with US exposure and increased with fiber intake, but increased with obesity. The observed paradoxical associations are not explained by host characteristics or variation in bacterial species but might be related to potential microbial co-occurrence, as seen by positive correlations among Roseburia, Prevotella, Dorea, and Coprococcus. In the conditional analysis with mutual adjustment, including all genera associated with both obesity and US exposure in the same model, the positive associations of Roseburia and Prevotella with obesity did not persist, suggesting that their positive associations with obesity might be due to their co-occurrence and correlations with obesity-related taxa, such as Dorea and Coprococcus. Conclusions Among US Hispanics/Latinos, US exposure is associated with unfavorable gut microbiome profiles for obesity risk, potentially related to westernized diet during acculturation. Microbial co-occurrence could be an important factor to consider in future studies relating individual gut microbiome taxa to environmental factors and host health and disease.

Background: Hispanic individuals have a disproportionately higher incidence and mortality for stomach, cervix, and liver cancers compared to Non-Hispanic White people. Since disparities in cancer incidence are influenced by multiple factors including immigration, elucidating the effect of birthplace and exposure to risk factors on the prevalence of these cancers is crucial for identifying high-risk populations and target risk reduction interventions.Methods: The National Institutes of Health All of Us Research Program is a prospective, multidimensional biomedical data resource of underrepresented, minoritized people. The Registered Tier Dataset v5 was utilized to evaluate the prevalence and risk of stomach, cervix, and liver cancers among United States (US) born and non-US born Hispanic participants.Results: Of over 434 000 current participants, 60 540 are Hispanic; 30 803 (50.9%) reported being US born and 29 294 (48.4%) non-US born. Non-US born Hispanic participants had significantly higher prevalence (.39% vs .21%, P < .001) and associated risk (OR 1.84, 95% CI 1.29-2.64, P < .001) of liver cancer, and trend towards higher prevalence of stomach (.14% vs .09%, P = .076) and cervix cancers (.27% vs .20%, P = .083) compared to US born counterparts. US born Hispanic patients with these 3 cancers were significantly younger than non-US born cohort (mean age 56.8 vs 61.7 years, P < .001).Discussion: This is the first report using All of Us data to show that non-US born Hispanic participants have a higher risk of liver cancer compared to US born participants. Further analyses, including genomic studies, are necessary to understand these differences and identify targets for risk reduction interventions. [ABSTRACT FROM AUTHOR]

The cytogenetic and molecular heterogeneity of acute myeloid leukemia (AML) is characterized as a contributing factor in the disparity of treatment outcomes and clinical outcomes seen among ethnic and racial groups. In this study, we have retrospectively evaluated the karyotypes of 800 adult Hispanic AML patients from Puerto Rico (PR). Acute promyelocytic leukemia with PML-RARA is the most common recurrent cytogenetic abnormality, compatible with previously published results. Among these AML patients, 163 patients had 21 gene panels performed. Twenty-six (15.95%) patients showed no detectable mutations, and 137 patients (84.05%) showed at least one mutation. Compared with previously published data from other examined Hispanic AML populations in the United States, mutational frequencies of these 21 genes, except for ASXL1 , WT1 , and KRAS , show no significant difference. This is the largest study to date about the landscape of cytogenetic and molecular abnormalities in Hispanic AML patients and a first report regarding the frequencies of these abnormalities in Puerto Rican Hispanic AML patients., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Arthrofibrosis is the most common postoperative complication of anterior cruciate ligament (ACL) reconstruction. It is caused by an exaggerated immune reaction to a pro-inflammatory trigger that causes abnormal periarticular fibrosis and joint stiffness. The shoulder, elbow, and knee are especially prone to this condition, often following trauma, surgery, or adhesive capsulitis. We describe the case of a 25-year-old Hispanic female who presented to the clinic with knee instability after experiencing a twisting and popping sensation in her left knee while playing tennis. Physical examination revealed increased anterior tibial translation, and imaging confirmed a torn ACL. She subsequently underwent ACL reconstruction using the bone-patellar tendon-bone graft technique. However, during her follow-up appointments, she reported persistent difficulties with active and passive range of motion in both flexion and extension despite undergoing appropriate physical therapy. Now, three months post-operation, she continues to experience limited knee range of motion. To our knowledge, there are only a few reports of arthrofibrosis in this particular age group and demographic undergoing this procedure. Our objective is to contribute this case to the scientific community, aiming to encourage future studies and gather epidemiological data on this topic., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Abstract Purpose To report normal values of macular and choroidal thickness obtained from a healthy Hispanic population using Optovue (Optovue Inc, Freemont CA, USA) spectral domain optical coherence tomography (SD-OCT). Design Observational, cross-sectional, correlation study. Methods A total of 290 eyes (145 healthy subjects) were included; 69% of subjects were female. The median age was 39 ± 29 years (IQR), with a range between 18 and 89 years. The study sample was stratified into three age groups: Group 1, 18–40 years (50.3%), Group 2, 41–60 years (30.7%), and Group 3, older than 61 years (19%). Central macular, perifoveal (inner quadrants), and parafoveal (outer quadrants) thicknesses were estimated. In addition, central and peripheral choroidal thicknesses were estimated. Data analysis was performed to calculate the standardized mean difference according to the variance (Student’s t-test) and its differences with Epidat 4.1. Results Median macular central thickness was 250 ±30 µm (IQR) with Optovue. Median central choroidal thickness was 263 ± 48 µm (IQR). Median central choroidal thickness was greater than mean peripheral thickness. Macular evaluation showed a statistically significant difference in central, perifoveal, and parafoveal thicknesses, with lower values being recorded for the study sample compared with the manufacturer’s data. Conclusions SD-OCT has become a useful tool to obtain high-resolution images of the macula and choroid. This method allows precise assessment of the retinal and choroidal layers to diagnose and follow up posterior segment diseases. We are reporting normal cut-off values of macular and choroidal thicknesses in healthy Hispanic subjects evaluated with Optovue SD-OCT as new diagnostic normal parameters for research and clinical activities.

Colorectal cancer (CRC) is a major public health problem, and its incidence is rising in developing countries. However, studies characterizing CRC clinicopathological features in cases from developing countries are still lacking. The goal of this study was to evaluate clinicopathological and demographic features in one of the largest CRC studies in Latin America.The study involved over 1525 CRC cases recruited in a multicenter study in Colombia between 2005 and 2014 as part of ongoing genetic and epidemiological studies. We gathered clinicopathological data such as age at diagnosis, sex, body mass index, tobacco and alcohol consumption, family history of cancer, and tumor features including location, histological type, and stage. Statistical analyses were performed to test the association between age of onset, sex, and clinical manifestations.The average age at CRC diagnosis was 57.4 years, with 26.5% of cases having early-onset CRC (diagnosed by age 50 years). Most cases were women (53.2%; P = 0.009), 49.2% were overweight or obese, 49.1% were regular alcohol drinkers, 52% were smokers/former smokers, and 12.2% reported relatives with cancer. Most tumors in the study were located in the rectum (42.7%), were adenocarcinomas (91.5%), and had advanced stage (T3-T4, 79.8%). Comparisons by sex found that male cases were more likely to be obese (36.5% vs 31.1%; P = 0.001), less likely to have a family history of cancer (9.7% vs 15.3%; P = 0.016), and more likely to have advanced-stage tumors (83.9% vs 76.1%; P = 0.036). Comparisons by age of onset found that early-onset cases were more likely to be women (59.3% vs 51.0%; P = 0.005) and report a family history of cancer (17.4% vs 10.2%; P = 0.001).To our knowledge, our study is the largest report of clinicopathological characterization of Hispanic CRC cases, and we suggest that further studies are needed to understand CRC etiology in diverse Hispanic populations.

Pediatric obesity and Attention Deficit Hyperactivity Disorder (ADHD) are rising health concerns in the United States, especially among Hispanic children and adolescents. Research on Hispanic children and adolescents indicates disproportionately higher prevalence rates of obesity in this community but scant data on ADHD prevalence rates. In contrast, a plethora of research studies across the general population examines the relationship between childhood obesity and ADHD. In addition, there is a lack of research that examines the role of ethnicity and sub-ethnic group correlations in ADHD, particularly in the Hispanic population. Existing studies in the general population indicate ADHD may be a risk factor for being overweight compared to normal controls. The objective of the present study is to examine the prevalence of obesity in children with ADHD compared to children in the general population in a predominately Hispanic sample on the US-Mexico border. A total of 7,270 pediatric medical records were evaluated. The retrospective analysis included Body Mass Index (BMI) and related health variables, and ethnicity and showed that children with ADHD are more likely to be underweight. In conclusion, no significant relationship existed between obesity and ADHD among Hispanic children on the US-Mexico Border, and instead we found the opposite correlation. [ABSTRACT FROM AUTHOR]

Abstract Background Most studies among Hispanics have focused on individual risk factors of obesity, with less attention on interpersonal, community and environmental determinants. Conducting community based surveys to study these determinants must ensure representativeness of disparate populations. We describe the use of a novel Geographic Information System (GIS)-based population based sampling to minimize selection bias in a rural community based study. Methods We conducted a community based survey to collect and examine social determinants of health and their association with obesity prevalence among a sample of Hispanics and non-Hispanic whites living in a rural community in the Southeastern United States. To ensure a balanced sample of both ethnic groups, we designed an area stratified random sampling procedure involving three stages: (1) division of the sampling area into non-overlapping strata based on Hispanic household proportion using GIS software; (2) random selection of the designated number of Census blocks from each stratum; and (3) random selection of the designated number of housing units (i.e., survey participants) from each Census block. Results The proposed sample included 109 Hispanic and 107 non-Hispanic participants to be recruited from 44 Census blocks. The final sample included 106 Hispanic and 111 non-Hispanic participants. The proportion of Hispanic surveys completed per strata matched our proposed distribution: 7% for strata 1, 30% for strata 2, 58% for strata 3 and 83% for strata 4. Conclusion Utilizing a standardized area based randomized sampling approach allowed us to successfully recruit an ethnically balanced sample while conducting door to door surveys in a rural, community based study. The integration of area based randomized sampling using tools such as GIS in future community-based research should be considered, particularly when trying to reach disparate populations.

Hereditary hemorrhagic telangiectasia (HHT), also known as Olser-Weber-Rendu, is a genetic disorder characterized by abnormal blood vessel formations. Inherited in an autosomal dominant pattern, the condition manifests through symptoms such as nosebleeds (epistaxis), spider-like blood vessels (telangiectasias) in mucous membranes often appearing as spots or lesions, and abnormal connections between arteries and veins. Here we present the case of a 66-year-old male who came to the emergency department (ED) with symptoms consistent with a respiratory tract infection. Relevant lab tests revealed a pattern of iron deficiency anemia, leading to a referral for management. Further investigation uncovered a long history of spontaneous nosebleeds, prompting a referral for genetic sequencing and analysis in the hopes of ruling out bleeding disorders. The test results were positive for a heterozygous pathogenic variant in the ACVRL1 gene, a gene associated with HHT and pulmonary arterial hypertension (PAH). Hereditary hemorrhagic telangiectasia is considered a relatively common disorder; however, there is a notable lack of comprehensive data regarding its prevalence within the Puerto Rican and broader Hispanic populations. This knowledge gap is significant because it hampers the ability to understand the full scope of the condition's impact and how it might present differently in diverse genetic backgrounds. Our goal is to enhance the understanding of HHT's prevalence and manifestations in these populations. This contribution is intended to support and stimulate further research, which could lead to more accurate epidemiological data, improved diagnosis, and a better understanding of the condition., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background Obese patients are at an increased risk of obstructive sleep apnea (OSA). Bariatric surgery or weight loss surgery is an important therapeutic measure in obese patients for the management of weight and comorbidities. Data are scarce in inner-city Hispanic and Black patients who undergo bariatric surgery, which eventually leads to health disparity in this minority population. Differences between patients with and without OSA have not been assessed in this population. This study aims to answer these questions. Methodology The study was conducted in a high-volume hospital in the Bronx, New York. Before bariatric surgery, patients underwent a preoperative evaluation that included a variety of blood tests, a sleep study, esophagogastroduodenoscopy, and echocardiography. They also underwent basic anthropometric measurements, such as weight, height, and body mass index (BMI), before surgery and 6 months and 12 months postoperatively. Additional calculations were made using these anthropometric measures, namely, total weight loss, excess weight loss, and delta BMI. Results Most patients were Hispanic (85.2%), with a mean age of 41.9 ± 10.8 years. We found that of the 108 patients included in the study, 69.4% (70/108) had OSA. Preoperative BMI in the study was 43.9 ± 13 kg/m 2 . Postoperatively, the mean decrease in BMI was 12.3 ± 14.5 kg/m 2 . Total weight loss and excess weight loss were 30.2 ± 14.3 and 52.6 ± 16.6, respectively. Conclusions In this study, no significant difference was noted in patients with or without OSA in either the laboratory or anthropometric parameters., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background and objective The incidence of hypertension is growing at an alarming rate globally. In the United States, nearly half of the adult population suffers from hypertension, a disease potentially associated with long-term dire consequences and comorbidities. While Internet access has proliferated, and free Internet-based education resources for healthy lifestyles have exponentially increased over the past two decades, little is known about whether Internet-based information can be or is used as a self-learning tool for hypertension management in a community setting. With almost no published data, if and to what degree Internet-based, self-directed learning tools are used for hypertension management needs to be assessed. In light of this, we aimed to evaluate the prevalence of Internet use as a source of information in patients with known diagnoses of hypertension who presented to our Internal Medicine clinic at Texas Tech University Health Sciences Center, El Paso. Materials and methods We conducted a single-center, cohort-based observational study at our teaching hospital's internal medicine clinic. A survey questionnaire was distributed to all adults aged more than 18 years with a known diagnosis of hypertension. Consent for participation was obtained from all participants. Of the total studied population, 93.6% (190/203) were of Hispanic descent. Moreover, 67.5% (137/203) identified as female. Of note, 22.7% (46/203) reported using the Internet to learn about hypertension. Internet users were younger, with a mean age of 61.4 years compared to 68.7 (p=0.02) years for non-Internet users, attended institutions of a higher grade of education, and mostly received information regarding hypertension from their families (91.3% vs 2.5%, p<0.001). While most patients used the Internet for making treatment decisions and were satisfied with their choices, more than a quarter felt confused and anxious after using Internet-based resources. Results Most patients in the study were found to not use the Internet as a resource tool for hypertension management (157/203; 77.3%). Among the 22.7% of patients who used the Internet for hypertension management, the most commonly utilized resource was Google.com, as an initial step to hypertension research (26/46, 58.6%, p<0.001), followed by multiple resources within a predetermined list on the provided survey (14/46, 30.4%). The survey also assessed the reasons for using Internet-based resources, with the primary reason being evaluating treatment options (19/46, 41.5%), followed by developing coping skills (13/46, 28.2%), and lastly aiding in decision-making (10/46, 21.5%). Conclusions Internet-based educational tools are mushrooming as the Internet is becoming more pervasive. This study shows that within this predominant Hispanic population, nearly one-quarter of patients with hypertension are using Internet-based, self-learning tools. This highlights a slow shift in medical education which providers have to be prepared for as patients will be using these tools as secondary information sources for medical decision-making more frequently going forward. Further studies need to be conducted to evaluate the current and longitudinal impact of these new information sources., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Hispanics make up 19% of the U.S. population and are experiencing rising rates of cancer, primarily due to an increase in infection-related cancers (gastric, hepatic, cervical) and advanced cancers secondary to delayed screening (colorectal, cervical, breast). There is an increased incidence of gastric cancer (associated with infection, obesity, alcohol, and tobacco use) in Hispanics, especially at a young age, highlighting the need to consider ethnicity as a risk factor., Methods: This study utilized the 2016-2019 National Inpatient Sample database to examine all patients admitted with gastric cancer. Individuals were stratified by race, age, and comorbidities, including modifiable risk factors that are associated with gastric cancer., Results: There were 5,785 (7.44%) patients aged 18-44, 28,370 (36.49%) aged 45-64, and 43,590 (56.07%) over 65 years of age. Notably, 34.3% of the youngest group were Hispanic, contrasted with 19.7% and 12.9% in the older groups, respectively. Younger Hispanic patients showed a higher prevalence of H. pylori infection (8.6%) compared with older Hispanics (3.6% in the middle age group and 2.1% in the oldest, p<0.01). There was a high prevalence of obesity, tobacco use, and gastric ulcers in this cohort. Other risk factors such as alcohol use and gastric polyps were present at a lesser prevalence., Conclusions: This study reveals that Hispanic patients tend to have a younger age of onset of gastric cancer, coupled with an increased incidence of H. pylori infection at a younger age. This finding underscores the potential benefit of H. pylori screening among asymptomatic young Hispanics with the aim of reducing gastric cancer morbidity and mortality in this population., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

Abstract Background Hispanics living in the USA may have unrecognized potential birthplace and lifestyle influences on the gut microbiome. We report a cross-sectional analysis of 1674 participants from four centers of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), aged 18 to 74 years old at recruitment. Results Amplicon sequencing of 16S rRNA gene V4 and fungal ITS1 fragments from self-collected stool samples indicate that the host microbiome is determined by sociodemographic and migration-related variables. Those who relocate from Latin America to the USA at an early age have reductions in Prevotella to Bacteroides ratios that persist across the life course. Shannon index of alpha diversity in fungi and bacteria is low in those who relocate to the USA in early life. In contrast, those who relocate to the USA during adulthood, over 45 years old, have high bacterial and fungal diversity and high Prevotella to Bacteroides ratios, compared to USA-born and childhood arrivals. Low bacterial diversity is associated in turn with obesity. Contrasting with prior studies, our study of the Latino population shows increasing Prevotella to Bacteroides ratio with greater obesity. Taxa within Acidaminococcus, Megasphaera, Ruminococcaceae, Coriobacteriaceae, Clostridiales, Christensenellaceae, YS2 (Cyanobacteria), and Victivallaceae are significantly associated with both obesity and earlier exposure to the USA, while Oscillospira and Anaerotruncus show paradoxical associations with both obesity and late-life introduction to the USA. Conclusions Our analysis of the gut microbiome of Latinos demonstrates unique features that might be responsible for health disparities affecting Hispanics living in the USA.

Purpose: To examine the burden and cost of diabetes among fee-for-service Medicare beneficiaries. Methods: Medicare 5% File data for type 1 diabetes (T1D) and type 2 diabetes (T2D) consisting of 1,397,933 enrollees in fee-for-service without Medicare Advantage during the period 2012?2013 were analyzed by race and ethnicity. Results: Although non-Hispanic whites (nHWs) comprised most of this population (86%), prevalence of T1D and T2D was higher for Hispanics than nHWs (3.4% vs. 1.8%, p=0.0006, for T1D and 33.4% vs. 21.9%, p

Purpose: Breast cancer remains the leading cause of cancer-related death in US Hispanic women. When present, lower health literacy levels potentially within this patient population require tailored materials to address health disparities. We aim to evaluate and compare Spanish and English online health care informative resources on preventive mastectomy. Methods: A Google web search using "preventive mastectomy" and "mastectomía preventiva" was conducted. The first ten institutional/organizational websites in each language were selected. Assessment of mean reading grade level, cultural sensitivity, understandability, and actionability was carried out utilizing validated tools. Results: The mean reading grade level for English materials was 14.69 compared with 11.3 for Spanish, both exceeding the recommended grade level established by the AMA and NIH. The mean cultural sensitivity score for English information was 2.20 compared with 1.88 for Spanish information, both below the acceptability benchmark of 2.5. English webpages scored 65% and 35% for understandability and actionability, respectively, while Spanish webpages scored 47% and 18%. Conclusions: Online English and Spanish preventive mastectomy materials were written at an elevated reading level and lacked cultural sensitivity. Spanish language information demonstrated inferior understandability, actionability, and cultural sensitivity. Addressing these issues provides an opportunity to help resolve health literature disparities regarding preventive mastectomy for US Hispanic women. [ABSTRACT FROM AUTHOR]

The inclusion of diverse populations in clinical trial research is a social justice imperative. Creating the communicative tools that can support cancer patients across varied cultural backgrounds in processing complex clinical trial information, to achieve informed consent, has been a challenge. This study sought to evaluate specific clinical trial multimedia-a website, four animations, and a decision aid-to meet the decision-making and informational needs of Hispanic patients. The multimedia content was positively evaluated by Hispanic cancer patients. However, the discussions also yielded important steps for culturally adapting these tools to account for particular informational needs and cultural values that would be important to incorporate into these, and future, clinical trial multimedia interventions that target Hispanic populations.

Objective: To determine the factors that might limit Hispanic patients from participating in dermatological clinical trials., Methods: From January 2022 to July 2022, we administered a 31-item, in-person questionnaire to patients recruited in the waiting area of the Caridad Center, one of the largest free clinics in the United States with a predominately Hispanic population, and a nearby private primary care clinic., Results: Overall, Hispanic patients agreed significantly more with statements in the domain of attitude and behavioral beliefs compared to non-Hispanic survey respondents. The Hispanic ethnicity was associated with increased odds of agreeing with the following statements: "My community would really benefit from skin cancer clinical trials" (OR=0.52; 95% CI 0.30, 0.92), "My participation in a skin cancer study would be very good" (OR=0.59; 95% CI 0.35, 0.99), and "I like to do good for others" (OR=0.41; 95% CI 0.22, 0.77)., Conclusion: While the United States population is composed of 18.5% Hispanics, they only account for 1% of patients enrolled in clinical trials. This study helps identify potential motivational factors for Hispanic patients to participate in skin cancer clinical trials., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Andrade et al.)

Design: Observational, cross-sectional, correlation study. Methods: A total of 290 eyes (145 healthy subjects) were included; 69% of subjects were female. The median age was 39 ± 29 years (IQR), with a range between 18 and 89 years. The study sample was stratified into three age groups: Group 1, 18–40 years (50.3%), Group 2, 41–60 years (30.7%), and Group 3, older than 61 years (19%). Central macular, perifoveal (inner quadrants), and parafoveal (outer quadrants) thicknesses were estimated. In addition, central and peripheral choroidal thicknesses were estimated. Data analysis was performed to calculate the standardized mean difference according to the variance (Student's t-test) and its differences with Epidat 4.1. Results: Median macular central thickness was 250 ±30 µm (IQR) with Optovue. Median central choroidal thickness was 263 ± 48 µm (IQR). Median central choroidal thickness was greater than mean peripheral thickness. Macular evaluation showed a statistically significant difference in central, perifoveal, and parafoveal thicknesses, with lower values being recorded for the study sample compared with the manufacturer's data. Conclusions: SD-OCT has become a useful tool to obtain high-resolution images of the macula and choroid. This method allows precise assessment of the retinal and choroidal layers to diagnose and follow up posterior segment diseases. We are reporting normal cut-off values of macular and choroidal thicknesses in healthy Hispanic subjects evaluated with Optovue SD-OCT as new diagnostic normal parameters for research and clinical activities.
