BACKGROUND: The Hokusai Venous Thromboembolism (VTE) Cancer trial demonstrated that edoxaban was noninferior to dalteparin for the treatment of cancer-associated venous VTE.
OBJECTIVES: We reanalyzed the trial using the win ratio, an approach that evaluates a composite of outcomes in a hierarchical order.
METHODS: Forty-nine thrombosis experts ranked 10 outcomes in order of clinical importance from all-cause death (most important) to clinically relevant nonmajor bleeding (least important). We performed unmatched pairwise comparisons between participants on edoxaban and those on dalteparin at 6- and 12-month follow-up. Within each pair, edoxaban was assigned a win, loss, or tie according to the hierarchy …

Age-associated reduced motivation is a hallmark of neuropsychiatric disorders in the elderly. In our rapidly aging societies, it is critical to keep motivation levels high enough to promote healthspan and lifespan. However, how motivation is reduced during aging remains unknown. Here, we used multiple mouse models to evaluate motivation and related affective states in young and old mice. We also compared the effect of social isolation, a common stressor in aged populations, to those of aging. We found that both social isolation and aging decreased motivation in mice, but that Bdnf expression in the ventral tegmental area (VTA) was selectively …

Background: Apolipoprotein E (APOE) alleles are well-established genetic risk factors for Alzheimer's disease (AD), but their effects on AD biomarkers (amyloid beta [Aβ]42/40, phosphorylated tau [p-tau]181, neurofilament light chain [NfL], and glial fibrillary acidic protein [GFAP]) may vary across populations due to ancestry-, age-, and sex-related differences. We hypothesized that these effects vary across Hispanic/Latino background groups with distinct ancestral admixture.
Methods: We analyzed ε2 and ε4 allele associations with AD biomarkers using survey-weighted linear regression models, adjusting for demographic covariates. Secondary analyses examined genetic analysis group- and ancestry-specific effects.
Results: ε4 was associated with lower Aβ42/40 and higher p-tau181and …

Background: There is growing interest in understanding the link between early life exposures to ambient air pollution and childhood blood pressure; however, existing findings, largely from single site/cohort studies, are inconclusive.
Methods: We examined the association between exposures to fine particulate matter (PM2.5) and nitrogen dioxide (NO2) and blood pressure measured at age 5-12 years in 4863 U.S. children from 20 pregnancy cohorts of the NIH ECHO cohort. Point-based residential exposures were derived from spatiotemporal models with a biweekly resolution and averaged over each trimester, the whole pregnancy, and child age 0-2 years. We converted systolic (SBP) and diastolic blood …

OBJECTIVE: Clinical frailty is associated with reduced long-term survival after fenestrated and branched endovascular aortic repair (F/BEVAR). This study assesses the impact of phenotypic clinical frailty on perioperative outcomes and cause of death following F/BEVAR for thoracoabdominal aortic aneurysm.
METHODS: Patients who underwent F/BEVAR at a single institution from 2012 to 2024 were identified. The clinical frailty scale (CFS) was used to determine phenotypic frailty. Patients with a preoperative CFS of ≥4 (vulnerable) and a CFS of < 4 were compared. We used χ
RESULTS: We included 233 patients; 60 (25.8%) had a CFS of ≥4 and 173 (74.2%) had a CFS of < 4. Patients with a CFS of ≥4 were more likely to have chronic obstructive pulmonary disease (53% vs 27%) and were treated for slightly larger aneurysms (72 mm vs 68 mm; P = .04). There were no differences in symptomatic presentation, aneurysm extent, or operative complexity between patient groups. Additionally, there were no differences in perioperative complications including 30-day mortality, stroke, and spinal cord ischemia. Patients with a CFS of ≥4 had an increased length of hospitalization (11.3 days vs 6.9 days; P < .01) and were less likely to return to preoperative functional status (62.7% vs 86.1%; P < .01). The 3-year all-cause and aortic-related mortality rates were 35.2% and 5.7%, respectively. Patients with a CFS of ≥4 had a lower survival at 1 year (74% vs 89%), 3 years (39% vs 73%), and 5 years (25% vs 56%), compared with patients with a CFS of < 4 (P < .01). The most common causes of death among both groups were pulmonary comorbidities (14.0%), oncologic conditions (14.0%), cardiovascular comorbidities (11.2%), and procedure-related complications (11.2%). Patients with a CFS of ≥4 were more likely to die from aortic-related mortality (10.3% vs 5.9%; P = .02), pulmonary comorbidities (15.4 vs 13.2%; P = .04), systemic decline (7.7% vs 1.5%; P = .02), and infection (12.8% vs 7.4%; P = .03). Aortic-related mortality for the entire patient cohort was 2.2% and 5.7% at 1 year and 3 years, respectively. Aortic-related deaths among clinically frail patients were often due to an inability to tolerate further aortic operations (eg, arch repair), and secondary to follow-up nonadherence in patients with a CFS of < 4.

Background: Although oral pre-exposure prophylaxis (PrEP) has been instrumental in decreasing HIV incidence, its daily dosing regimen poses adherence challenges. Using an agent-based network model informed by empirical data, we simulate the impact of introducing long-acting injectable (LAI) PrEP among young Black men who have sex with men (YBMSM) in Los Angeles County, a group disproportionately affected by HIV.
Setting: Computer simulations using an agent-based network model.
Methods: We modeled HIV transmission among YBMSM over 10 years under scenarios varying the proportion of PrEP users opting for LAI instead of oral medications and adherence levels to LAI retention. The model …

We explored gaming elements as a tool to promote engagement in HIV prevention services among Latino men who have sex with men. We conducted thematic content analysis of semistructured interview data that we collected from 12 Latino men who have sex with men (April-August 2022) in South Florida. Themes emerged related to intervention delivery, components, and perceptions. Our findings will guide the development of a game-based intervention to improve preexposure prophylaxis and HIV prevention engagement among Latino men who have sex with men.

PURPOSE: Osteosarcoma is the most common primary bone tumor in childhood and adolescence. Many patients face long-term impairments in their mobility and function after treatment, leading to a decrease in their quality of life. Exercise has been shown to improve functional recovery and improve quality of life in patients with cancer, though data specific to children with osteosarcoma are sparse. Exercise has also been shown to be feasible in patients undergoing chemotherapy, with numerous potential benefits to health and quality of life. To design the most effective exercise interventions for children and adolescents with osteosarcoma, we must first understand the …

Population stratification is one of the source of inflation in epigenome-wide association studies (EWAS) when not properly accounted for. To address this, we developed methylation population scores (MPSs) to predict genetic principal components (GPCs) using a feature selection approach. We used multi-ethnic DNA methylation data from Illumina EPIC arrays across five cohorts, including MESA (n = 929), CARDIA (n = 1123), JHS (n = 1365), ARIC (n = 2338), and HCHS/SOL (n = 1475), randomly splitting participants into training (85%) and test (15%) sets. Within each cohort, associations between GPCs and CpG sites were estimated using linear regression adjusting for …

The Brown Foundation: Institute of Molecular Medicine
Repeated ethanol exposure during adolescence increases adult anxiety risk, but the underlying mechanisms remain unclear. The paraventricular nucleus of the thalamus (PVT) has been considered a hub for controlling anxiety and is affected by experiences from early life. Thus, this study investigated how adolescent intermittent repeated ethanol exposure (AIE) affects the PVT activities and anxiety-related behaviors in adulthood. We found that AIE triggers anxiety-like behaviors and parallelly exhibited elevated firing rates and increased calcium signaling in the PVT neurons compared to control counterpart mice. Chemogenetic inhibition of PVT neurons reduced anxiety-like behaviors in AIE-treated animals, confirming PVT's role in adolescent …

INTRODUCTION: Transcranial ultrasound stimulation (TUS) shows great promise for inducing neuroplastic changes that persist long after stimulation. Evidence of stimulation-locked (online) neural changes would enable the development of closed-loop application of TUS. However, such responses have been difficult to distinguish from coincident neural activity caused by auditory and somatosensory effects of TUS.
METHODS: To dissociate genuine online neuromodulatory effects from peripheral confounds, we leveraged the contralateral retinotopic organization of the early visual cortex in nineteen subjects. Using a hemifield visual stimulation paradigm combined with high-precision, functional MRI-guided TUS, we applied TUS to the left early visual cortex while participants viewed …

Background: While substantial research has focused on first-line (1L) therapies for advanced-stage non-small cell lung cancer (aNSCLC), less is known about the effectiveness of second-line (2L) treatments following disease progression on 1L. The poor prognosis after 1L progression, limited guidance for 2L treatment, and constraints of clinical trials in addressing these questions underscore the need for real-world comparative effectiveness research.
Methods: We conducted a retrospective analysis to compare real-world overall survival (rwOS) associated with 2L treatments among patients with disease progression during 1L. Eligible patients were selected from Flatiron Health's nationwide electronic health record (EHR)-derived de-identified database. 1L and 2L …

Background: Prenatal exposure to tobacco smoke may impair neurodevelopment in children. However, accurately characterizing this exposure remains challenging.
Methods: We pursued two objectives in this large population study. First, in 1708 pregnant women from the Environmental Influences on Child Health Outcomes (ECHO) cohort, we constructed Receiver Operating Characteristic (ROC) curves to determine urinary cotinine cut-offs to classify firsthand (FHS), environmental (ETS), and no exposure, and further distinguished secondhand (SHS) from thirdhand smoke (THS) exposure within ETS. Second, among 1593 participants in three pregnancy cohorts nested in ECHO, we fit multivariable linear regressions to examine the association between the newly defined …

Given the morbidity and mortality associated with colorectal cancer (CRC), novel biomarkers are clearly warranted, especially for early detection. An antibody-based screen of 2000 proteins was utilized to identify stool proteins that were elevated in patients with CRC, compared with healthy controls (HCs). Thirty-seven lead candidates were selected for ELISA validation in three independent cohorts comprised of CRC patients, advanced adenoma patients, and HCs, drawn from two different ethnicities. Of the 2000 proteins interrogated, 116 were differentially expressed in CRC stool, with 45 being elevated at twofold or higher; 37 of these proteins were selected for ELISA validation in three …

Introduction: Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects 5 to 8% of youth and 2.5 to 4% of adults. Pharmacological treatments are among the most effective when treating ADHD, yet adherence to medication is still sub-optimal. We reviewed the literature on clinical and socio demographic factors that may influence adherence and compared it to our clinical data.
Methods: We conducted a targeted literature review on factors associated with ADHD medication adherence. These factors were compared within our sample of patients aged 3-18 with ADHD at the Child and Adolescent Mood Disorders Program (ChAMP) at (UT Health) - Houston. …

Stroke is associated with autonomic dysfunction and reduced acetylcholine (ACh), a neurotransmitter critical for cognition. ACh signals in part through the alpha-7 nicotinic acetylcholine receptor (α7nAChR), a ligand-gated ion channel involved in synaptic plasticity, learning, and memory. Impaired α7nAChR signaling has been linked to heightened neuroinflammation and poor acute stroke recovery. Here, we investigated whether α7nAChR contributes to post-stroke cognitive recovery in young male mice. Wild-type (WT) and α7nAChR knockout (α7n0KO) mice underwent 60-min middle cerebral artery occlusion (MCAO). In a pharmacology cohort, the α7nAChR agonist GTS-21 was administered immediately after reperfusion and then daily for 20 days. Cognitive performance …

The COMMANDS trial established luspatercept as a first‐line treatment for anemia in transfusion‐dependent lower‐risk (LR) myelodysplastic syndromes (MDS). Here we report red blood cell (RBC) transfusion response analysis based on somatic mutations profile and disease risk for patients treated with luspatercept or epoetin alfa in the COMMANDS trial. Of 350 evaluable patients, 238 (68.0%) had MDS with multiple lineage dysplasia and ring sideroblasts (RS) according to World Health Organization 2016 criteria, and 320 (91.4%) had somatic mutations in ≥ 1 gene (median, 2) with median variant allele frequencies (VAF) of 2%–59%. Mutation profiles were similar in the treatment groups. Luspatercept …
