BACKGROUND:Cardiovascular disease is the most common cause of morbidity and mortality in kidney transplant recipients. Screening for coronary disease is frequently required prior to kidney transplantation, but coronary intervention has not been shown to be beneficial except in complex coronary artery disease. The likelihood of finding significant coronary artery disease and the benefits of routine pre-transplant screening are uncertain. METHODS:We performed a systematic review and meta-analysis. Medline & Embase were searched to identify manuscripts published between 1998 and 2024 reporting the results of pre-transplant screening. The primary endpoints were the frequency of detecting significant coronary lesions for which there are AHA class 1 indications for revascularization: a) >50% left main stenosis; or b) multi-vessel disease with ejection fraction < 35% during pre-kidney transplant screening. Secondary endpoints included frequency of detecting multivessel disease, proximal left anterior descending artery (LAD) disease, and number of patients who underwent invasive coronary angiography. Meta-regression was used to explore outcome heterogeneity according to the presence of hypertension, diabetes, and age. RESULTS:We identified 1273 studies out of which 44 met eligibility criteria. The mean prevalence of class 1 indications was 2%, although the heterogeneity was high with estimates ranging from 0% to 17%. Estimated prevalence of proximal LAD disease was 2% and left main stenosis was 1%, whereas 10% of patients had multi-vessel coronary artery disease, and 35% were referred for invasive angiography. There was no evidence of significant heterogeneity according to sex of the population or prevalence of diabetes or hypertension. CONCLUSIONS:Identification of class I indications for revascularization during pre-transplant coronary screening was rare.

OBJECTIVE:People with migraine have a higher prevalence and severity of insomnia. We examined the relationship between insomnia severity and migraine-related disability (MIDAS) and migraine-specific quality of life (MSQv2.1). METHODS:We conducted a post-hoc analysis of a pilot randomized controlled study assessing the RELAXaHEAD application in those with insomnia and comorbid migraine. Descriptive statistics were used to summarize demographic and clinical characteristics. Linear mixed model analysis was conducted to evaluate Insomnia Severity Index (ISI) as a predictor of each MSQv2.1 domain and MIDAS. RESULTS:Forty-two participants completed baseline and at least one follow-up survey. Mean age was 43.8 years (SD 12.6) and the majority (85.7%) were female. Most participants (81.0%) had severe migraine-related disability (median baseline MIDAS, 32 (IQR 52)). Over half (54.8%) of participants had moderate clinical insomnia (mean baseline ISI, 18.5 (SD 4.6)). Baseline median MSQv2.1 scores were 44.3 (IQR 31.4) for Role Function-Restrictive (RFR), 65.0 (IQR 45.0) for Role Function-Preventive (RFP), and 46.7 (IQR 46.7) for Emotional Function (EF). The effect of ISI on MIDAS was statistically significant (rate ratio (RR)=1.10, p < 0.05, 95%CI [1.028, 1.171], meaning each one-point increase in ISI was associated with a 10% higher MIDAS score). Additionally, a 1-point increase in ISI was associated with a decrease of 1.2 points in MSQ-RFR (B=-1.205, p = 0.001),1.0 point in MSQ-RFP (B=-0.981, p = 0.020), and 1.4 points in MSQ-EF (B=-1.66, p = 0.001). CONCLUSIONS:Our study revealed significant associations between insomnia severity and migraine-related disability and quality of life, highlighting the importance of prevention and sleep intervention for patients with migraine.

IMPORTANCE/UNASSIGNED:Colorectal cancer screening rates in the US remain suboptimal, particularly among low-income and minoritized populations, despite the availability of effective, low-cost options such as the fecal immunochemical test (FIT). Scalable outreach strategies are needed to improve uptake and reduce staff burden in safety-net settings. OBJECTIVE/UNASSIGNED:To evaluate whether a behavioral economics-informed, automated text messaging strategy was associated with increased FIT completion compared with nurse-led telephone call outreach. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This quality improvement randomized clinical trial was conducted from April 7 to June 24, 2025, at 8 Federally Qualified Health Centers (FQHCs) in Brooklyn, New York, within the Family Health Centers at NYU Langone. Participants included adults (aged ≥18 years) with a new FIT order who listed English, Spanish, or Chinese (Mandarin or Cantonese) as their preferred language and had not opted out of text messaging. INTERVENTION/UNASSIGNED:Patients were randomized 1:1 to receive either 3 automated, 1-way text message reminders on days 2, 5, and 8 (intervention) or a single nurse-led telephone call reminder on day 8 (usual care). MAIN OUTCOMES AND MEASURES/UNASSIGNED:The primary outcome was FIT completion within 21 days of the test order, assessed from the electronic health record. Secondary outcomes included completion at 7 and 14 days. FIT completion at 7, 14, and 21 days was compared between groups using χ2 tests. RESULTS/UNASSIGNED:Among 1275 eligible randomized participants, 649 were assigned to the text group (418 female participants [64.4%]; mean [SD] age, 56.4 [9.3] years) and 626 to the telephone group (398 female participants [63.6%]; mean [SD] age, 56.7 [9.6] years). FIT completion within 21 days was higher in the text group (382 of 649 participants [58.9%]) compared with the telephone group (312 of 626 participants [49.8%]) with an absolute difference of 9.0 percentage points (95% CI, 3.6-14.5 percentage points; P = .001). Post hoc analyses found no evidence of differential effectiveness by age, sex, race and ethnicity, or patient portal use. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this quality improvement randomized clinical trial, a behaviorally informed text messaging strategy was associated with significantly improved FIT completion compared with usual nurse-led telephone outreach. Automated messaging may offer a scalable, low-cost strategy to promote preventive care and reduce staff burden in underserved populations.

IMPORTANCE/UNASSIGNED:Syringe services programs (SSPs) are evidence-based interventions that reduce bloodborne infections and injection-related harms among people who inject drugs, yet access remains limited and geographically uneven across the US. OBJECTIVE/UNASSIGNED:To quantify the travel time, distance, and cost required to reach the nearest SSP from population-weighted census tracts nationwide and to examine differences by urbanicity, state, and SSP legality. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This cross-sectional geospatial study linked all known SSP locations as of August 2024 to the population-weighted centroids of census tracts in the 50 US states and the District of Columbia. Analyses were conducted between December 2024 and February 2026. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Population-weighted mean and median driving time, distance, and cost to access the nearest SSP, stratified by National Center for Health Statistics urban-rural county category and SSP legal status. Costs were estimated using 2024 Internal Revenue Service (IRS) medical mileage deduction rates and 2022 state-specific gasoline prices. RESULTS/UNASSIGNED:In 1338 SSPs across 83 780 census tracts, the population-weighted mean 1-way driving time to the nearest SSP was 46.1 minutes (95% CI, 45.7-46.5 minutes) and the median was 23.3 minutes (IQR, 12.2-58.5 minutes). Altogether, 23.1% of the population lived more than 60 minutes from an SSP and 12.6% lived over 120 minutes away. The mean 1-way driving distance was 41.8 miles (95% CI, 41.3-42.2 miles). The mean 1-way driving cost was $8.77 (95% CI, $8.68-$8.86) using the 2024 IRS mileage rate and $6.91 (95% CI, $6.84-$6.98) using state mean gasoline prices in 2022. In states where SSPs were legal, mean driving time was 30.1 minutes (95% CI, 29.8-30.4 minutes) and mean cost by IRS mileage rates was $4.94 (IQR, $4.88-$5.00), compared with 110.7 minutes (95% CI, 109.6-111.8 minutes) and $24.19 (IQR, $23.92-$24.46) in states where SSPs were illegal. CONCLUSIONS AND RELEVANCE/UNASSIGNED:This cross-sectional study of travel burden to SSPs found substantial geographic and financial barriers to accessing SSPs across the US, particularly in nonmetropolitan areas. Targeting new SSPs to areas with the greatest travel burden could improve utilization and reduce drug-related morbidity.

IMPORTANCE/UNASSIGNED:The association between stroke severity and dementia is well established. However, reports on trajectories of cognitive decline comparing stroke survivors with individuals without stroke in large cohorts are insufficient. OBJECTIVES/UNASSIGNED:To examine associations of ischemic stroke incidence and severity with cognitive decline and dementia risk and to explore whether vascular risk factors modify these associations. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This cohort study pooled longitudinal data on cognitive function of participants aged 45 years or older and without stroke and dementia at baseline from 3 US prospective cohorts: the Atherosclerosis Risk in Communities study (1987-2019), Framingham Offspring Study (1971-2019), and Reasons for Geographic and Racial Differences in Stroke study (2003-2019). First definite ischemic strokes were reported in each cohort using consistent protocols, with severity defined using the National Institutes of Health Stroke Scale (NIHSS). The data analysis was completed February 27, 2026. EXPOSURE/UNASSIGNED:Incident ischemic stroke categorized as minor (NIHSS 0-5), mild to moderate (NIHSS 6-10), or moderate to severe (NIHSS ≥11). MAIN OUTCOMES AND MEASURES/UNASSIGNED:The primary outcomes were decline in global cognition and incident dementia. Secondary outcomes were changes in memory and executive function. Multivariable linear mixed-effects models were used to test the association of stroke incidence and severity with cognitive decline. RESULTS/UNASSIGNED:A total of 42 342 participants from the pooled cohorts were included (mean [SD] age, 61.3 [9.8] years; 55.0% female). Longitudinal cognitive testing data were available for a median of 11.1 years (range, 0-29.7 years) with 397 344 person-years of observation for dementia incidence. Stroke severity data were available for 1055 of 1505 first-ever ischemic stroke survivors (70.1%). Compared with participants with no stroke, adjusted hazard ratios for incident dementia were 1.93 (95% CI, 1.52-2.45) for NIHSS 0 to 5, 3.26 (95% CI, 1.93-5.53) for NIHSS 6 to 10, and 5.06 (95% CI, 2.71-9.45) for NIHSS 11 or higher. Over the follow-up, higher stroke severity was associated with progressively steeper cognitive declines across all domains, with more prevalent dose-response associations for global cognition (ranging from a mean -0.18 [95% CI, -0.19 to -0.18] points per year for no stroke to -0.58 [95% CI, -0.73 to -0.42] points per year for moderate to severe stroke) and memory (ranging from a mean -0.15 [95% CI, -0.16 to -0.14] points per year for no stroke to -0.36 [95% CI, -0.51 to -0.21] points per year for moderate to severe stroke) than for executive function (ranging from a mean -0.33 [95% CI, -0.34 to -0.32] points per year for no stroke to -0.52 [95% CI, -0.66 to -0.39] points per year for moderate to severe stroke). CONCLUSIONS AND RELEVANCE/UNASSIGNED:This large cohort study of participants from 3 prospective cohorts found that greater stroke severity was associated with substantially elevated dementia risk and accelerated decline in global cognition, memory, and executive function. These findings underscore the critical importance of stroke prevention, particularly severe stroke, and identifying mechanisms that may link stroke to cognitive decline.

INTRODUCTION/BACKGROUND:Neutrophil-to-lymphocyte ratio (NLR), a marker of systemic inflammation, has been linked to dementia risk, but prior studies were limited by small sample sizes. METHODS:We assessed the association between baseline NLR and incident Alzheimer's disease (AD) and Alzeimer's disease and related dementias (AD/ADRD) using electronic health records from New York University (NYU) (n = 284,530) and the Veterans Health Administration [VA] (n = 85,836) Hospitals from 2011 to 2023. AD/ADRD diagnoses were identified via International Classification of Diseases (ICD) codes ≥6 months post-baseline. Cox models and cumulative incidence functions (CIFs) adjusted for demographic and clinical variables, with death as a competing risk. RESULTS:Higher NLR was associated significantly with increased AD/ADRD risk in both cohorts (NYU hazard ratio [HR] = 1.07, 95% confidence interval [CI] 1.02-1.15; VA HR = 1.21, 95% CI 1.10-1.34). Spline analysis further confirmed a continuous dose-response relationship, and subgroup analyses showed higher risk among female and Hispanic patients. DISCUSSION/CONCLUSIONS:Elevated NLR is independently associated with higher AD/ADRD risk across diverse populations, highlighting the role of systemic inflammation and neutrophil-mediated pathways in neurodegeneration.

Household chaos has been shown to be an important predictor across multiple domains of children's development, with both direct associations and indirect associations through changes in parenting practices. Yet, little is known about these associations among immigrant families. Data from the Children, Community, and Caregivers (C3) Study of the larger Together Growing Strong place-based initiative among predominantly Chinese and Latine immigrant families in the Sunset Park neighborhood of Brooklyn, New York were used to examine cross-sectional associations between household chaos and child behavior and receptive vocabulary at child ages 4 and 6 (N = 187). The STROBE checklist for cross-sectional research was adhered to. Linear regression models were used to examine unique contributions of variables, as well as structural equation modeling to examine mediation through parenting stress. As a supplemental exploratory analysis, differences in associations between household chaos and child behavior and language by race/ethnicity were further examined. There were significant positive associations between household chaos and parental reports of children's problem behavior (β = 0.21, 95% CI [0.07-0.35]) and significant negative associations between household chaos and direct assessments of children's receptive vocabulary (β=-0.21, 95% CI [-0.37 - -0.04]). Further, there were indirect associations of household chaos through parenting stress for child problem behavior only (β = 0.11, 95% CI [0.05-0.17]). The results for the main linear regression models and mediation models were primarily driven by Chinese families. Implications for predictors of child development in immigrant populations and the enduring salience of household chaos are discussed.

BACKGROUND:Sugary drink taxes have been implemented in several U.S. jurisdictions, but we know little about the impact of taxes on calories purchased in restaurants. The impact may differ in restaurant (vs. non-restaurant) settings because restaurant consumers may be less likely to travel to other jurisdictions for a single meal, choose no beverage or non-taxed beverages, decrease their beverage size, or order combo meals where the drink is bundled with other items at a single price. METHODS AND FINDINGS/RESULTS:We used six years of transaction-level sales data (2015-2020) from 7,341 Taco Bell restaurant locations to estimate the association of sugary drink policies with beverage calories purchased in the drive-through setting of fast food restaurants over time. Taco Bell restaurants represents a large sample size of data from several U.S. jurisdictions across a long follow-up period, which is unique in the literature. We defined the treatment group as restaurants in five jurisdictions where taxes were ever implemented (Albany, CA; Cook County, IL; Oakland, CA; Philadelphia, PA; Seattle, WA) (n = 60 restaurants). We identified a group of comparison restaurants where taxes were never implemented using synthetic control methods (n = 60 restaurants). We used a difference-in-differences design with calendar month and restaurant fixed effects to compare changes in outcomes between groups between the baseline (3-14 months prior to tax implementation) and 3- to 24-month follow-up periods, overall and by jurisdiction. Our primary outcome measure was beverage calories per transaction, from individually-purchased beverages and combo meals (separately). In the baseline period, average beverage calories per transaction were 51.1 (SD = 8.6) in the tax group and 42.3 (SD = 7.4) in the comparison group; and 119.5 (SD = 15.3) and 115.0 (SD = 23.0) beverage calories per transaction in combo meals. Overall, we observed no association between taxes and changes in beverage calories per transaction between groups during the follow-up period, including from individual beverage items (difference-in-differences = -0.3 (95% CI [-0.8, 1.2]) and combo meals (difference-in-differences = -4.3 (95% CI [-13.5, 5.0]). We observed similar results by location, except in Oakland, CA, where customers purchased 16.8 (95% CI 19.6, 14.1) fewer beverage calories per transaction from combo meals; the association was null after conditioning on the purchase of a beverage (difference-in-differences = -1.01 [-4.93, 2.92)]). The main limitations of our study methodology include the exclusion of beverage calorie data from in-store transactions and that the majority of the restaurants in our sample were located in Cook County. CONCLUSIONS:Though we observed differences in certain jurisdictions, overall our findings suggest that sugary drink taxes may not be effective in reducing beverage calorie consumption in fast food restaurants.
