Perceived Racial and Ethnic Discrimination, Depression, and Alcohol Use Intentions Among Inner-City Latinx Youth: Cross-Generational Effects.

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.

Omnibus or Ominous immigration laws? Immigration policy and mental health of the Hispanic population.

This study examines the impact of Omnibus Immigration Laws on the mental health of the Hispanic populations in the U.S. We use a Difference-in-Differences framework and data from the Behavioral Risk Factor Surveillance System Survey of Centers for Disease Control and Prevention for the 2000-2016 period that contains information on more than 400 thousand Hispanics residing in the U.S. We find that the most stringent provision, namely, "show me your papers" laws, adversely affects the mental health of Hispanics and contributes to an increase of 12%-16% in the number of unhealthy mental days and an increase of 13%-18% in the probability of having frequent mental distress in the states with "show me your papers" laws. OIL provisions that enforced the use of E-Verify or limited the use of public benefits to unauthorized immigrants did not have any effect on mental health. The study also examines (1) police stops, (2) physical health, insurance, and employment status, (3) co-ethnic density, and (4) immigration enforcement awareness as potential mechanisms that could lead to a deterioration in the mental health of Hispanics. The evidence indicates their vulnerability to strict immigration enforcement. The social and public health cost should be carefully evaluated when formulating and implementing immigration policies.

A Brief Report: Comparative Evaluation of Online Spanish and English Content on Pancreatic Cancer Treatment.

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.

Evaluation of online Spanish and English health materials for preventive mastectomy. are we providing adequate information?

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.

Signet Ring Cell Gastric Carcinoma: Clinical Epidemiology and Outcomes in a Predominantly Latino County Hospital Population.

BACKGROUND: Gastric 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. AIMS: To 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. METHODS: We 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. RESULTS: We identified 63 patients with GSRC. Compared to SEER, our cohort was significantly younger (52.6 vs. 63.5 years, p < 0.01), Hispanic/Latino predominant (81% vs. 20%, p < 0.01), had higher overall stage (86% vs. 69% with stage III/IV, p < 0.01), and more frequent node involvement (89% vs. 49%, p < 0.01). Lower tumor stage, Helicobacter pylori positivity, and surgical intervention were associated with significantly longer median survival (all p < 0.05), which was similar in our study compared to SEER (median 12.6 vs. 9.0 months, p = 0.26). CONCLUSIONS: Patients with GSRC within the Los Angeles County population have different clinical characteristics compared to what has been reported in SEER. Our cohort was younger, and despite having more advanced disease, did not have shorter survival. Further study is needed to better identify protective and risk factors in this population and improve understanding of the etiopathogenesis and natural history of this malignancy.

An Evaluation of Clinical Trial Multimedia to Support Hispanic Cancer Patients' Informational and Decision-Making Needs.

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.

Area based stratified random sampling using geospatial technology in a community-based survey.

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.

Identifying Associations Between Influenza Vaccination Status and Access, Beliefs, and Sociodemographic Factors Among the Uninsured Population in Suffolk County, NY.

Seasonal influenza continues to impose a substantial healthcare and economic burden in the United States each year. This study assessed influenza vaccination rates among the uninsured population, determined the need for free flu vaccines, and analyzed associations of vaccination status with access, beliefs, and sociodemographic factors. Stony Brook Outreach and Medical Education (SB HOME) free clinic offers free flu vaccinations to uninsured patients over the age of 18 living in Suffolk County, New York. All patients visiting SB HOME between October 2018 and February 2019 were offered a 10-min anonymous survey assessing demographic characteristics, self-evaluation of health status, vaccination status during the 2017-2018 and 2018-2019 flu seasons, willingness to obtain a free flu vaccine, and beliefs and barriers surrounding flu vaccines. Analysis consisted of descriptive statistics, paired t tests, and χ2 tests using a significance threshold of p < 0.05. A total of 102 participants were surveyed, 80% of whom identified as Hispanic/Latino. The majority of participants expressed positive attitudes towards the influenza vaccine. Despite these positive attitudes, 72% reported not receiving the influenza vaccination during the 2017-2018 flu season, the commonly cited reasons being fear of getting sick from the flu vaccine, high cost, and not knowing where to get the vaccine. During the 2018-2019 flu season 60% of participants elected to receive a free flu shot at SB HOME, and participants with positive attitudes towards flu vaccines were more likely to accept the vaccine when offered at no cost. Fear of getting sick from the flu vaccine remained the most common reason for participants declining a free flu vaccine. Only 17% of participants would seek vaccination at the market price of $30, compared to the 76% who would if the vaccine was offered for free. Our study highlights the need for convenient and affordable access to the flu vaccine among uninsured populations, who despite recognizing the benefits of receiving the flu vaccine are unable to overcome certain barriers. Elucidating and targeting barriers specific to uninsured populations at the local community level may improve public health strategies centered on increasing vaccination rates.

Tiempo de Vacunarte (time to get vaccinated): Outcomes of an intervention to improve HPV vaccination rates in a predominantly Hispanic community.

The purpose of this study was to evaluate effects of a culturally tailored evidence-based HPV vaccine educational intervention on psychosocial factors and vaccine completion in a largely low-income Hispanic population. Our study is a prospective community based intervention utilizing a prepost design. We recruited individual's dwelling in a border community aged 18-26 years or parents/guardians of children aged 9-17 years who had not completed the HPV vaccine series. We recruited 2380 participants between June 2015 and February 2018. We included 1796 participants in the final analysis. Mean age of the sample was 22.8 years (SD2.60). Majority of participants 63.99 were female and self-identified as Hispanic (97.4%). A total of 3192 vaccines were administered with an overall vaccine completion rate of 39.8%; 31.6% among adult participants compared to 48.7% among children. The Intervention significantly improved HPV knowledge by 61.66%, HPV awareness by 19.45%, Intention to vaccinate by 13.85%. For both adults and children being born in Mexico significantly improved the odds of vaccine completion (AOR: 2.154 95% CI: 1.439-3.224), while for adults only pre-intervention perceived benefits remained significant (AOR 1.101, CI: 1.002-1.210) and in children the main factor was parental perceived susceptibility of their child (AOR: 1.257 CI: 1.001-1.578). A Community based multicomponent HPV vaccine intervention significantly improved HPV immunization rates in a largely Hispanic population. Factors that affect completion of the HPV series are different among adults and children.

Vitamin D levels and fracture risk among Hispanic children.

PURPOSE: There is a lack of knowledge about whether low vitamin D levels increase the risk of pediatric low-energy fractures among Hispanic population. The objective of this study is to determine whether there is a direct relationship between low vitamin D levels and the incidence of low-energy fractures in Hispanic children. METHOD: Cases included all consecutive patients evaluated with low-energy fractures in the pediatric orthopedic clinic. The control group consisted of all pediatric patients evaluated, without fractures, who had bone and joint pain complaints in the general pediatric clinic. The main focus was to compare cases and controls in relation to their vitamin D levels. Cases and controls were compared using t tests for means of quantitative variables and Chi-square tests. RESULTS: A total of 201 subjects, distributed as cases (n = 107) and controls (n = 94), were included in this study. One hundred twelve (55.7%) of the total study population were males. The mean age for the study population was 8.6 years old ranging from 1 year to 18 years, and standard deviation = 4.0 years. The median age for the study population was 9 years. The mean vitamin D level for the cases was 32.6 ng/dl (SD = 10.9); the mean vitamin D level for controls was 32.3 ng/dl (SD = 13.4). This difference was not statistically significant (t = 0.18, 95% CI - 3.2 to 3.9; p = 0.854). CONCLUSION: A direct relationship between low vitamin D levels and fracture risk in a Hispanic pediatric population was not established. LEVELS OF EVIDENCE: III.

Validation of the Simplified Criteria for the Diagnosis of Autoimmune Hepatitis in Chilean-Hispanic Patients.

INTRODUCTION AND AIM: In 2008 the International autoimmune hepatitis (AIH) Group proposed the simplified diagnostic criteria for this disease. The original cohort study was performed in 11 international centers, but validation studies are scarce in Latin-America. The aim of this study is validate these criteria in Hispanic patients. MATERIAL AND METHODS: A retrospective cohort of patients undergoing percutaneous liver biopsy and follow-up of at least 12 months was recruited from a Chilean University hospital. Patients with previous immunosuppressive therapy and liver transplant recipients were excluded. The diagnostic accuracy was analyzed using as gold standard the clinical course during long-term follow-up. Sensitivity, specificity, positive and negative predictive values (PPV and NPV) and area under the ROC curve (AUROC) were calculated. RESULTS: Four hundred eighty one patients were evaluated, 294 were included. 218 (74.15%) were female, mean age 48.5 (± 12.3) years, mean follow-up 34 (± 18) months. 66 patients had AIH or overlap syndrome (22.45%), 96 (32.65%) non-alcoholic steatohepatitis, 40 (13.61%) primary biliary cholangitis, 31 (10.54%) hepatitis C, 8 (2.72%) hepatitis B, 53 (18.02%) other etiologies. The AUROC for AIH simplified criteria was 0.976. Using a cutoff ≥ 6 and ≥ 7 points, the sensitivity was 86.4% and 54.6%; specificity, 98.7% and 99.6%; PPV, 95% and 97.3%; and NPV, 96.2% and 88.6%, respectively. CONCLUSION: Simplified criteria for the diagnosis of AIH have a high accuracy in our Chilean-Hispanic cohort. The female gender is strongly associated to AIH and could help in difficult cases. Further studies with a prospective design are necessary to confirm these observations.

Cephalomedullary nails: factors associated with impingement of the anterior cortex of the femur in a Hispanic population.

INTRODUCTION: Impingement and penetration of the anterior cortex of the femur have been reported as complications after cephalomedullary nailing. The purpose of this study was to determine factors related to nail impingement in our population of Hispanic patients. MATERIALS AND METHODS: A non-matched case-control study was carried out and 156 patients who underwent cephalomedullary nailing from 2010 and 2013 were included; 78 cases with anterior cortical impingement and 78 control cases without impingement were documented. Demographic variables and specifications of the nails such as manufacture and radius of curvature were recorded. The presence of impingement, angle of incidence on radiographs--indirect measurement of the femoral bow on the sagittal plane--and nail entry site were determined. Bivariate and multivariate logistic regression analyses were performed to identify the factors associated with cortical impingement. RESULTS: The distribution by sex corresponded to 87 females (56%) and 69 males (44%) with a mean age of 75 years [SD 18.2]. Cortical impingement was presented in 78 cases (50%) and 6 (3.8%) patients evidenced penetration of the anterior cortex of the femur. On the bivariate analysis the posterior nail start site is highlighted, which showed a positive association with impingement (OR 4.3; 95% CI 1.1-36 and p = 0.04). After the multivariate analysis, the factors associated with anterior cortical impingement included female gender (OR 2.2; 95 % CI 1.1-4.6 and p ≤ 0.038), straight nails-short nails-(OR 4.9; 95% CI 2.2-10 and p ≤ 0.001) and angle of incidence ≥7° (OR 4.9; 95% CI 2.2-10 and p ≤ 0.001), the latter showing a likelihood of 57 % for impingement, increasing to 90% with an angle of incidence of 11°. CONCLUSIONS: Posterior entry site should be avoided and an anterior site should be used. Female gender, straight nails and greater angle of incidence of the femur were associated with cortical impingement. A specific intramedullary nail design is needed for the Hispanic population due to high impingement and anterior cortical penetration rates seen with conventional nails. Short curved nails and long nails with a lower radius of curvature are required.

The effect of periodontal therapy on glycaemic control in a Hispanic population with type 2 diabetes: a randomized controlled trial.

OBJECTIVE: In the Mexican-American population, the prevalence of Type 2 diabetes mellitus (T2DM) is as high as 50% of the population. This randomized controlled clinical trial was designed to elucidate how treatment of periodontal disease affects HbA1c values in this population. MATERIALS AND METHODS: One hundred and fifty-four T2DM patients with periodontal disease were enrolled in the study. The test group was treated with scaling and root planing (SRP); the control group received oral hygiene instructions. At baseline and 4-6 weeks after therapy, a complete periodontal examination was performed. Blood was collected at baseline and 4 months later for HbA1c levels. RESULTS: One hundred and twenty-six individuals completed the study. Baseline mean ± SD HbA1c for the test and control groups were 9.0 ± 2.3% and 8.4 ± 2.0% respectively. Non-significant difference in HbA1c reductions (0.6 ± 2.1% and 0.3 ± 1.7%) was found between test and control groups at 4 months. Comparisons of the periodontal clinical parameters between the test and control groups found significant differences with improved results in the test subjects. CONCLUSIONS: No statistically significant differences were found in the changes of HbA1c levels between test and control groups. Non-surgical periodontal therapy improved the magnitude of change in periodontal parameters as compared to the control subjects. ClinicalTrials.gov Identifier: NCT01128374.

Oral health status, perceptions, and access to dental care in the Hispanic population.

This article analyzes the results of a survey designed to assess self-reported oral health status, perceptions, and access to care between the Hispanic population and the general population of the United States. A nationally representative telephone survey was conducted with randomly selected participants: 1000 each from the Hispanic and the general populations. Responses of both groups were compared and statistically analyzed at a 95% confidence level (α = 0.05). The results showed significant differences between the Hispanic and the general populations. Hispanics were less likely to believe in the need for regular professional dental care, more likely to have misperceptions about oral health and conditions, and less likely to have access to care than the general population. Hispanics were less likely to have visited a dentist in the last 2 years, and significantly more Hispanics than general population participants cited cost of care and lack of dental insurance as key reasons for not seeing a dentist. More information on good oral health habits, Spanish-language information, and where to access care were identified as helpful tools by majorities of Hispanics. These data indicate disparities do exist between the Hispanic and the general populations. They highlight the need for new policies and programs-from organized dentistry to individual practices-that address the needs of the growing Hispanic population.

Knowledge, Attitudes, and Perceptions of Skin Cancer Clinical Trials in the Hispanic Population.

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.

Respiratory Tract Infection Leading to the Diagnosis of Hereditary Hemorrhagic Telangiectasia in a Puerto Rican Patient: A Case Report.

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.

Are We Missing the Mark? Understanding Health Literacy in A Rural-Border Hospital.

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.

A Severe Case of Arthrofibrosis After Anterior Cruciate Ligament (ACL) Reconstruction in a 25-Year-Old Female Hispanic Patient: A Case Report.

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.

Optimizing tacrolimus dosing in Hispanic renal transplant patients: insights from real-world data.

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 patient weighing 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 0.1 mg/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.

Nativity Disparities in Colorectal Cancer Screening Among Hispanics in the United States.

Hispanics in the United States (U.S.) have previously exhibited lower guideline-concordant colorectal cancer (CRC) screening uptake than non-Hispanic (NH) Whites, with disparities accentuated in foreign-born Hispanics, however it is unclear whether nativity-related CRC screening disparities have changed in the last two decades and whether these disparities are attenuated after adjusting for socioeconomic and demographic characteristics. We evaluated CRC screening adherence in foreign- and U.S.-born Hispanics compared to U.S.-born NH Whites. We used 2019 National Health Interview Survey data to compare the prevalence of up-to-date CRC screening per the 2019 U.S. Preventive Services Task Force recommendations among Hispanic nativity subgroups (i.e., foreign- and U.S.-born) and U.S.-born NH Whites using unadjusted and adjusted weighted log-linked binomial regression. Foreign- and U.S.-born Hispanics had a significantly lower unadjusted prevalence of up-to-date screening than U.S.-born NH Whites (47.18% and 64.18% versus 70.70%; p < 0.0001 and p = 0.0109, respectively). After adjusting for socioeconomic and demographic differences, the prevalence of up-to-date screening was lower in foreign-born Hispanics compared to U.S.-born NH Whites [adjusted prevalence ratio 0.80 (95% confidence interval 0.70-0.91)]; however, no statistically significant difference was observed between U.S.-born Hispanics and NH Whites. Our results suggest a low screening uptake in foreign-born Hispanics independent of socioeconomic and demographic differences. Future interventions should target foreign-born Hispanics to address disparities and promote early detection and prevention of CRC regardless of socioeconomic factors.
