We present an empirically benchmarked framework for sex-specific normative modeling of brain morphometry that can inform about the biological and behavioral significance of deviations from typical age-related neuroanatomical changes and support future study designs. This framework was developed using regional morphometric data from 37,407 healthy individuals (53% female; aged 3-90 years) following a comparative evaluation of eight algorithms and multiple covariate combinations pertaining to image acquisition and quality, parcellation software versions, global neuroimaging measures, and longitudinal stability. The Multivariate Factorial Polynomial Regression (MFPR) emerged as the preferred algorithm optimized using nonlinear polynomials for age and linear effects of global measures as covariates. The MFPR models showed excellent accuracy across the lifespan and within distinct age-bins, and longitudinal stability over a 2-year period. The performance of all MFPR models plateaued at sample sizes exceeding 3,000 study participants. The model and scripts described here are freely available through CentileBrain (https://centilebrain.org/).

Importance: It is unclear whether the duration of amyloid-β (Aβ) pathology is associated with neurodegeneration and whether this depends on the presence of tau.
Objective: To examine the association of longitudinal atrophy with Aβ positron emission tomography (PET)-positivity (Aβ+) and the estimated duration of Aβ+ (Aβ+ duration), controlling for tau-positivity.
Design, Setting, And Participants: Data for this longitudinal cohort study were drawn from the Wisconsin Registry for Alzheimer Prevention and the Wisconsin Alzheimer Disease Research Center Clinical Core Study.

Background: Conventional top-down health interventions often exclude adolescents and community stakeholders from service design and implementation, resulting in low uptake and a mismatch with young people's needs. The CAFFP-PAC initiative in Northern Uganda sought to explore how a community-led, adolescent-centered inception process could support integration of adolescent-friendly family planning and post-abortion care into primary healthcare services.
Methods: A participatory qualitative design was employed during an inception meeting in Lira City on April 1, 2025, guided by principles of community-based participatory research and citizen science.

While BAG3 has been identified as a causative gene for dilated cardiomyopathy, the major pathological events in BAG3-related cardiomyopathy that could be targeted for therapeutic benefit remain to be discovered. Here, we aim to uncover novel pathological events through genetic studies in a zebrafish bag3 cardiomyopathy model. Given the known cardioprotective effects of mtor inhibition and the fact that transcription factor EB (tfeb) encodes a direct downstream phosphorylation target of mTOR signaling, we generated a cardiomyocyte-specific transgenic line overexpressing tfeb (Tg[cmlc2:tfeb]).

High-risk eating behavior, including the consumption of rare hamburgers and undercooked chicken as gourmet dishes, is a public health concern. Identifying the factors associated with such consumers' risky-eating behaviors is necessary to develop effective risk communication strategies. However, previous studies have primarily focused on undercooked meat resulting from mishandling during preparation, with few addressing the consumption of risky foods and its determinants.
