Identifying the Molecular Signatures of Organic Matter Leached from Land-Applied Biosolids via 21 T FT-ICR Mass Spectrometry.

Intensification of wastewater treatment residual (i.e., biosolid) applications to watersheds can alter the amount and composition of organic matter (OM) mobilized into waterways.

Complementary Peptide Interactions Support the Ultra-Rigidity of Polymers of De Novo Designed Click-Functionalized Bundlemers.

Computationally designed 29-residue peptides yield tetra-α-helical bundles with symmetry. The "bundlemers" can be bifunctionally linked via thiol-maleimide cross-links at their N-termini, yielding supramolecular polymers with unusually large, micrometer-scale persistence lengths. To provide a molecularly resolved understanding of these systems, all-atom molecular modeling and simulations of linked bundlemers in explicit solvent are presented.

A Granzyme B-Cleavable T Cell-Targeted Bispecific Cell Vesicle Connector for Reversing New-Onset Type 1 Diabetes.

Type 1 diabetes (T1D) is an autoimmune disorder in which pancreatic β-cells are destroyed by CD8 T cells. Anti-CD3 antibody effectively treats early-stage T1D when β-cell autoantibodies are detected but before symptoms appear. However, it impairs the immune system temporarily, exposing individuals to infection.

Identifying the Strongest Correlates of Condom Use Among US Adolescents: A Systematic Review and Meta-Analysis.

Importance: Condoms are effective at preventing sexually transmitted infections and pregnancy; however, only 52% of sexually active US adolescents used a condom at last intercourse.

Objective: To examine (1) the association between 36 psychosocial variables and adolescent condom use to determine the strongest correlates of condom use behavior across the literature, (2) heterogeneity of these effects, and (3) the moderating roles of age, gender/sex, race/ethnicity, sexual orientation, and year of study.

Data Sources: A systematic search was conducted of studies published between January 2000 and February 2024 using Medline, CINAHL, PsycINFO, and Communication Source databases, plus relevant review articles and unpublished data.

Exploring Maternal Resilience among Predominantly Low-Income and Minoritized Women.

Background: Research has increasingly explored maternal resilience or protective factors that enable women to achieve healthier maternal and child outcomes. However, it has not adequately examined maternal resilience using a culturally-relevant, socio-ecological lens or how it may be influenced by early-life stressors and resources. The current study contributes to the literature on maternal resilience by qualitatively exploring the salient multi-level stressors and resources experienced over the lifecourse by predominantly low-income and minoritized women.

Seeing Into the Future: Adults' Accuracy Predicting the Vocabulary of Early Symbolic Communicators Who Use Augmentative and Alternative Communication.

Purpose: Vocabulary access is important for individuals who use augmentative and alternative communication (AAC), especially for children in the early stages of language learning. This study sought to understand how accurate speech-language pathologists (SLPs), teachers, and parents are in predicting the vocabulary needed by early symbolic communicators who use AAC in three contexts.

Method: Ten groups, each with a child who used AAC as their primary mode of communication and who was classified as an early symbolic communicator and their parent, teacher, and SLP, participated.

A Rise in Reactive Criminal Thinking Over the Course of a 10-Week Prison-Based Programme Predicts Increased Criminal Propensity: Testing the Exportation Hypothesis.

Background: The importation model holds that inmate behaviour is a function of behaviours and thought patterns offenders bring with them into prison from the community. It may also be that offenders export behaviours and thought patterns they develop or refine in prison when they return to the community.

Aims: The purpose of this study was to determine whether an increase in reactive criminal thinking in prisoners predicts recidivism following release.

Mesonephric and Mesonephric-like Adenocarcinomas of the Gynecologic Tract: A Case Series and a Review of the Literature.

We sought to present and describe all cases of mesonephric adenocarcinoma (MNAC) and mesonephric-like adenocarcinomas (MLAs) at our institution. These cancers are rare, morphologically similar tumors of the female reproductive tract. In this case series, we present 13 new cases of MNAC/MLA that were identified at St.

Strength of Genetic Associations with Thyrotropin Values Differs Between Populations with Similarity to African and European Reference Populations.

Epidemiological data suggest the population distribution of thyrotropin (TSH) values is shifted toward lower values in self-identified Black non-Hispanic individuals compared with self-identified White non-Hispanic individuals. It is unknown whether genetic differences between individuals with genetic similarities to African reference populations (GSA) and those with similarities to European reference populations (GSE) contribute to these observed differences. We aimed to compare genome-wide associations with TSH and putative causal TSH-associated variants between GSA and GSE groups.

Exploring the role of T cells in Alzheimer's and other neurodegenerative diseases: Emerging therapeutic insights from the T Cells in the Brain symposium.

This proceedings article summarizes the inaugural "T Cells in the Brain" symposium held at Columbia University. Experts gathered to explore the role of T cells in neurodegenerative diseases. Key topics included characterization of antigen-specific immune responses, T cell receptor (TCR) repertoire, microbial etiology in Alzheimer's disease (AD), and microglia-T cell crosstalk, with a focus on how T cells affect neuroinflammation and AD biomarkers like amyloid beta and tau.

Investigation of Genomic and Transcriptomic Risk Factors of Clopidogrel Response in African Americans.

Clopidogrel, an anti-platelet drug, is used to prevent thrombosis after percutaneous coronary intervention. Clopidogrel resistance results in recurring ischemic events, with African Americans (AA) suffering disproportionately. The aim of this study was to discover novel biomarkers of clopidogrel resistance in African Americans using genome and transcriptome data.

Functional independence trajectories over 5 years in older veterans with traumatic brain injury: A model systems study.

Background: Research on older adults who sustain a traumatic brain injury (TBI) has predominantly been on civilian, nonveteran populations. Military populations experience higher rates of TBI and often experience the additive effects of TBI and other comorbid disorders, including posttraumatic stress disorder and/or substance use that may increase disability over time.

Objective: To investigate predictors of functional independence trajectories over the 5 years after TBI in veterans 55 years or older at injury.

Genetic Services in Appalachia Conference Series.

This study examined the data generated as part of a seven-session webinar series that focused on genetics care provision in the medically underserved, rural Appalachian region and examined how these services have adapted to challenging practice environments. Barriers and facilitators to care in our region were considered. Data included a baseline survey of registrants, transcripts of sessions, and feedback about sessions.

Beyond Food Assistance: A Scoping Review Examining Associations of Nonfood Social Safety Net Programs in the United States With Food Insecurity and Nutrition Outcomes.

Objective: To conduct a scoping review to summarize the state of the evidence on associations between participation in nonfood social safety net programs (eg, income assistance, housing assistance) in the United States and food- and nutrition insecurity-related outcomes.

Background: Food and nutrition insecurity are persistent public health challenges in the United States that increase chronic disease risk and exacerbate health disparities. Several food assistance programs enhance food and nutrition security.

Evaluating the Impact of a Safe Exercise Training on Clinician Knowledge and Self-Efficacy in Managing Dysfunctional Exercise in an Eating Disorder Treatment Setting.

Introduction: Dysfunctional exercise (DEX) is common among individuals with an eating disorder (ED) and poses significant challenges to treatment and recovery. While safe and nutritionally supported physical activity can enhance treatment outcomes without hindering weight restoration, clinicians often hesitate to address DEX with their patients. This mixed-method study aimed to evaluate the impact of a Safe Exercise at Every Stage (SEES) informed training on clinician knowledge and self-efficacy in managing DEX during ED treatment.

A neuropathology case report of a woman with Down syndrome who remained cognitively stable: Implications for resilience to neuropathology.

Introduction: Aging adults with Down syndrome (DS) accumulate Alzheimer's disease (AD) neuropathology, including amyloid beta plaques and neurofibrillary tangles, by age 40.

Methods: We present findings from an individual with DS who remained cognitively stable despite AD neuropathology. Clinical assessments, fluid biomarkers, neuroimaging, and neuropathological examinations were conducted to characterize her condition.

Medication Use Quality and Safety in Older Adults: 2023 Update.

Improving the quality of medication use and medication safety are important priorities for healthcare providers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2023. We selected high-quality studies that advanced this field of research.

A multi-cohort study of longitudinal and cross-sectional Alzheimer's disease biomarkers in cognitively unimpaired older adults.

Introduction: The generalizability of neuroimaging and cognitive biomarkers in their sensitivity to detect preclinical Alzheimer's disease (AD) and power to predict progression in large, multisite cohorts remains unclear.

Method: Longitudinal demographics, T1-weighted magnetic resonance imaging (MRI), and cognitive scores of 3036 cognitively unimpaired (CU) older adults (amyloid beta [Aβ]-negative/positive [A-/A+]: 1270/1558) were included. Cross-sectional and longitudinal cognition and medial temporal lobe (MTL) structural measures were extracted.

Four targets: an enhanced framework for guiding causal inference from observational data.

Observational studies play an increasingly important role in estimating causal effects of a treatment or an exposure, especially with the growing availability of routinely collected real-world data. To facilitate drawing causal inference from observational data, we introduce a conceptual framework centered around "four targets"-target estimand, target population, target trial, and target validity. We illustrate the utility of our proposed "four targets" framework with the example of buprenorphine dosing for treating opioid use disorder, explaining the rationale and process for employing the framework to guide causal thinking from observational data.
