Socioeconomic position (SEP) in childhood and beyond may influence the gut microbiome, with implications for disease risk. Studies evaluating the relationship between life-course SEP and the gut microbiome are sparse, particularly among Hispanic/Latino individuals, who have a high prevalence of low SEP. We use the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a population-based cohort study conducted in four field centers in the United States (U.S.), to evaluate the association between life-course SEP and gut microbiome composition. Life-course SEP indicators included parental education (proxy of childhood SEP), current SEP (n = 2174), and childhood (n = 988) and current economic hardship (n = 994). Shotgun sequencing was performed on stool samples. Analysis of Compositions of Microbiomes was used to identify associations of life-course SEP indicators with gut microbiome species and functions. Parental education and current SEP were associated with the overall gut microbiome composition; however, parental education and current education explained more the gut microbiome variance than the current SEP. A lower parental education and current SEP were associated with a lower abundance of species from genus Bacteroides. In stratified analysis by nativity, we found similar findings mainly among foreign-born participants. Early-life SEP may have long-term effects on gut microbiome composition underscoring another biological mechanism linking early childhood factors to adult disease.

People with HIV are at increased risk of cardiovascular events; thus, care delivery strategies that increase access to comprehensive cardiovascular disease (CVD) risk management are a priority. We report the results of a multi-component telemedicine-based strategy to improve blood pressure control among people with HIV-Assess and Adapt to the Impact of COVID-19 on CVD Self-Management and Prevention Care in Adults Living with HIV (AAIM-High). The AAIM High strategy is a virtual adaptation of our previously published EXTRA-CVD strategy and consisted of hypertension education and six components: nurse-led care coordination (delivered by teleconference or telephone), home systolic blood pressure (SBP) monitoring, evidence-based treatment algorithms, electronic health records tools, technology coach, and communication preferences assessment. People with HIV (n = 74) with comorbid hypertension at three academic medical centers were enrolled in a single arm implementation study from January 2021 to December 2022. Over 12 months, the average patient-performed home SBP decreased by 7.7 mmHg (95% CI -11.5, -3.9). The percentage of patients at treatment goal, defined as average SBP <130 mmHg, increased from 46.0% to 72.5% at 12 months. By adapting to the growing use of telemedicine in healthcare delivery, our study effectively improved hypertension control in people with HIV through a virtual, nurse-led intervention.

BACKGROUND/UNASSIGNED:Systematic screening individuals with non-invasive devices may improve diagnosis of atrial fibrillation (AF) and reduce adverse clinical events. We systematically reviewed the existing literature to determine the yield of new AF diagnosis associated with systematic AF screening, the relative increase in yield of new AF diagnosis with systematic screening compared to usual care, and the effect of systematic AF screening on clinical outcomes compared with usual care. METHODS/UNASSIGNED:The Medline, Embase, Web of Science and Cochrane Library databases were searched from inception through 1st February 2025 for prospective cohort studies or randomised clinical trials (RCTs) of systematic AF screening with the outcome of incidence of previously undiagnosed AF from screening. Incidence rates (IR) and relative risks were calculated and random effects meta-analysis performed to synthesise rates of AF in prospective cohort studies and RCTs, as well as outcomes in RCTs. FINDINGS/UNASSIGNED:From 3806 unique records we included 32 studies representing 735,542 participants from 8 RCTs and 24 prospective cohorts. The diagnosis rate for incident AF in prospective cohorts was 2.75% (95% CI 1.87-3.62), and the pooled relative risk in RCTs was 2.22 (95% CI 1.41-3.50). The use of age and NT-proBNP (IR 4.36%, 95% CI 3.77-5.08) or AF risk score classification (4.79%, 95% CI 3.62-6.29) led to higher new AF diagnosis yields than age alone (0.93%, 95% CI 0.28-2.99). Pooled data from RCTs did not demonstrate an effect of screening on death (RR 1.01, 95% CI 0.97-1.05), cardiovascular hospitalisation (1.00, 95% CI 0.97-1.03), stroke (0.95, 95% CI 0.87-1.04) or bleeding (1.08, 95% CI 0.91-1.29). INTERPRETATION/UNASSIGNED:Systematic screening for AF using non-invasive devices is associated with increased diagnosis of AF, but not reduced adverse clinical events. Screening studies of AF utilising alternative risk stratifications and outcome measures are required.

AIMS/OBJECTIVE:To characterize trends in obesity and prescriptions for glucagon-like peptide-1 receptor agonists (GLP-1RAs) across body mass index (BMI) categories among US youth and adults with type 1 diabetes (T1D) from 2008 to 2023. MATERIALS AND METHODS/METHODS:Patients with T1D were identified using a validated algorithm using de-identified electronic health record (EHRs) data from 33 US health systems. BMI categories were based on age- and sex-specific percentiles for youth (2-19 years) and World Health Organization cut points for adults (≥20 years). Trends in obesity and GLP1-RA prescriptions were characterized by BMI categories among youth and adults with T1D from 2008-2011 to 2020-2023. RESULTS:From 2008-2011 to 2020-2023, the prevalence of obesity among youth with T1D increased from 18.1% (95% confidence interval [CI], 17.3%-18.9%) to 26.0% (25.2%-26.8%) (p-for-trend < 0.001). Among adults with T1D, the prevalence of obesity rose from 30.5% (30.0%-31.0%) in 2008-2011 to 38.1% (37.8%-38.5%) in 2020-2023 (p-for-trend < 0.001). Obesity was highest in Black and Hispanic youth and adults, and racial and ethnic disparities persisted over time. Over the last 15-year period, GLP-1RA prescriptions significantly increased across all BMI categories in a dose-response manner among both youth and adults with T1D (all p-for-trend < 0.001). CONCLUSIONS:Over the last 15-year period, obesity has reached epidemic levels in US youth and adults with T1D, with significant disparities among racial and ethnic minoritized populations. These findings, coupled with the increase in GLP-1RA prescriptions, underscore the urgent need for data on GLP-1RAs' safety and effectiveness and guidance for obesity management in T1D.

BACKGROUND AND OBJECTIVES/OBJECTIVE:Disturbances in brain catecholamine activity may be associated with symptoms after exposure to repetitive head impacts (RHIs) or related chronic traumatic encephalopathy (CTE). In this article, we studied CSF catecholamines in former professional and college American football players and examined the relationship with football proxies of RHI exposure, CTE probability, cognitive performance, neuropsychiatric symptoms, and parkinsonism. METHODS:In this observational cross-sectional study, we examined male former American football players, professional ("PRO") or college ("COL") level, and asymptomatic unexposed male ("UE") individuals from the DIAGNOSE CTE Research Project. Catecholamines-norepinephrine (NE) and its metabolite, 3,4-dihydroxyphenylglycol (DHPG), and dopamine (DA) and its precursor, 3,4-dihydroxyphenylalanine (l-DOPA), and metabolite, 3,4-dihydroxyphenylacetic acid (DOPAC)-were measured in CSF with high-performance liquid chromatography and compared across groups with analysis of covariance. Multivariable linear regression models tested the relationship between CSF catecholamines and proxies of RHI exposure (e.g., total years of playing American football), factor scores for cognition, and neurobehavioral dysregulation (explosivity, emotional dyscontrol, impulsivity, affective lability), as well as depressive/anxiety symptoms, measured with the Beck Depression/Anxiety Inventories. CTE probability and parkinsonism were assessed using the National Institute of Neurological Disorders and Stroke consensus diagnostic criteria for traumatic encephalopathy syndrome (TES), and biomarkers were compared among different diagnostic groups. RESULTS:The cohort consisted of 120 former American football players (85 PRO players, 35 COL players) and 35 UE participants (age 45-75). Former players had significantly lower levels of NE (mean difference = -0.114, 95% CI -0.190 to -0.038), l-DOPA (-0.121, 95% CI -0.109 to -0.027), and DOPAC (-0.116, 95% CI -0.177 to -0.054) than UE participants. For NE and DOPAC, these overall group differences were primarily due to differences between the PRO and UE cohorts. No significant differences were found across TES-CTE probability subgroups or TES-parkinsonism diagnostic groups. Within the COL cohort, tested as post hoc analyses, higher CSF NE and l-DOPA were associated with higher neurobehavioral dysregulation factor scores, BAI total score, and worse executive functioning and processing speed. CSF DHPG and DOPAC were associated with impulsivity only in this subgroup. DISCUSSION/CONCLUSIONS:We observed reduced CSF catecholamine concentrations in former elite American football players, although the relationship with degree of RHI exposure and the clinical impact needs further study.

PURPOSE/OBJECTIVE:This study evaluated how frequently patients with early onset colorectal cancer received fertility counseling and whether patient characteristics affected the likelihood of receiving such counseling. METHODS:We conducted a single-center retrospective review of all new patients seen by medical oncology for colorectal cancer who were age 55 years or younger for men and 50 years or younger for women. Associations between patient demographics and clinical characteristics with receipt of fertility counseling were explored using univariate analyses and multivariable logistical regression analyses. RESULTS:A total of 194 patients were included, of whom 15.5% received fertility counseling. Using multivariate analysis, we found that age < 40 (OR 15.587, p < 0.0001, 95% CI 4.841-50.191) and female sex (OR 3.979, p = 0.0292, 95% CI 1.150-13.770) were correlated with increased likelihood of fertility counseling. Patients living in areas of higher household income were more likely to receive fertility counseling, with a statistically significant difference between the 3rd and 1st quartiles of income (p = 0.0369, 95% CI 1.161-115.940). CONCLUSION/CONCLUSIONS:A majority of patients with EOCRC did not receive fertility counseling despite the known toxicities of CRC treatment modalities on fertility. Older age, male sex, and residence in areas of lower income were associated with decreased likelihood of receiving fertility counseling.

INTRODUCTION/BACKGROUND:Research has demonstrated that food insecurity during childhood is associated with worse physical and mental health in childhood. However, little is known about how food insecurity during childhood impacts health outcomes in young adulthood. METHODS:This study analyzed data from the Future of Families and Child Wellbeing Study (2024), a longitudinal birth cohort study of children born in 1998-2000. Childhood food insecurity trajectory groups from age 3 to 15 years were identified using group-based trajectory modeling. Associations between childhood food insecurity trajectory groups and young adult weight (BMI, overweight status, and obese status) and high self-reported health (good/excellent) at age 22 were modeled with multivariate linear and logistic regression. RESULTS:Three trajectories were identified among 4,296 participants: 66.9% were food secure, 7.5% were food insecure, and 25.6% transitioned from being food insecure-to-secure throughout childhood. In adjusted analyses, young adults assigned to the food insecure-to-secure trajectory group as children had higher BMI (B 0.82, 95% CI [0.07-1.58]) and higher odds of overweight status (OR 1.24, 95% CI [1.01-1.52]) than young adults assigned to the food secure trajectory group as children. Young adults in the food insecure trajectory group as children had lower odds of high self-reported health than those in the food secure trajectory group as children (OR 0.65, 95% CI [0.48-0.89]). CONCLUSIONS:Food insecurity in childhood is associated with high weight status and poor self-reported health in young adulthood. These findings highlight the importance of childhood food insecurity screening and interventions to promote health throughout the life course.

OBJECTIVES/OBJECTIVE:To study the impact of an educational intervention on obstetrician-gynecologist clinicians' knowledge of racial and ethnic disparities in the menopause experience. METHODS:Twenty-five obstetrician-gynecologist physicians (residents, fellows, and attendings) at an academic medical center in New York, NY, completed the Achieving Menopausal Health Equity Network course, a brief web-based intervention consisting of four modules delivered through narrated didactic videos and interactive tools, a 10-item pretest and posttest, and a course evaluation survey. The primary outcome was a change in knowledge scores after the completion of the educational intervention. Item analysis was also performed to assess item discrimination, item difficulty, and response frequency. Feedback on modules was obtained, and thematic analysis was performed. RESULTS:In this study, 25 participants completed the educational intervention. There was a statistically significant increase in mean test scores after participation (pretest mean score=7.1/10 vs. posttest mean score=8.1/10, P =0.0021). The following themes emerged in thematic analysis: knowledge building with potential for practical application for clinicians and non-clinicians, clarity and relevance, and opportunities for growth for future iterations of the modules. CONCLUSIONS:This brief, online educational curriculum focused on racial and ethnic disparities in menopause significantly improved the knowledge of obstetrician-gynecologist clinicians at various levels of training and provides a useful model for introducing more formal training on menopause medicine for obstetrician-gynecologist clinicians.

BACKGROUND:The Tobacco, Alcohol, Prescription Medication, and Other Substance (TAPS) tool is a screening and brief assessment instrument to identify unhealthy tobacco, alcohol, drug use, and prescription medication use in primary care patients. This secondary analysis compares the TAPS tool to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) for alcohol screening. METHODS:Adult primary care patients (1124 female, 874 male) completed the TAPS tool followed by AUDIT-C. Performance of each instrument was evaluated against a reference standard measure, the modified World Mental Health Composite International Diagnostic Interview, to identify problem use and alcohol use disorder (AUD). Area under the curve (AUC) appraised discrimination, and sensitivity and specificity were calculated for Youden optimal score thresholds. RESULTS:For identifying problem use: On the AUDIT-C, AUC was 0.90 (95% Confidence Interval: 0.86-0.92) for females and 0.91 (0.89-0.93) for males. Sensitivity and specificity for females were 0.89 (0.83-0.93) and 0.78 (0.75-0.80), respectively, and for males were 0.84 (0.79-0.88) and 0.82 (0.79-0.85). On the TAPS tool, AUC was 0.82 (0.79-0.86) for females and 0.81 (0.78-0.84) for males. Sensitivity and specificity for females were 0.78 (0.72-0.84) and 0.78 (0.75-0.81), respectively, and for males were 0.76 (0.71-0.81) and 0.76 (0.72-0.79). For AUD: On the AUDIT-C, AUC was 0.90 (0.88-0.93) for both females and males. Sensitivity and specificity for females were 0.83 (0.74-0.90) and 0.83 (0.80-0.85), respectively, while for males, they were 0.81 (0.74-0.87) and 0.84 (0.81-0.87). On the TAPS tool, AUC was 0.84 (0.80-0.89) for females and 0.82 (0.78-0.86) for males. Sensitivity and specificity for females were 0.73 (0.63-0.81) and 0.85 (0.83-0.88), respectively, while for males, they were 0.75 (0.68-0.81) and 0.84 (0.81-0.86). CONCLUSION/CONCLUSIONS:The AUDIT-C performed somewhat better than the TAPS tool for alcohol screening. However, the TAPS tool had an acceptable level of performance for alcohol screening and may be advantageous in practice settings seeking to identify alcohol and other substance use with a single instrument.
