Epidemiology of bacterial biofilms on polyps and normal tissues in a screening colonoscopy cohort.

Background: Invasive bacterial biofilms are implicated in colorectal cancer. However, their prevalence on histologically normal tissues and polyps is not well established, and risk factors of biofilms have not been previously investigated. Here we evaluated potential procedural and demographic risk factors associated with biofilm status using a cross-sectional observational cohort.

A Closer Look: Examining Cultural-Contextual Influences on Weight Management Through Focus Groups With Church-Going African American Women.

Chronic diseases continue to rise among African American women making lifestyle programs a critical aspect of risk reduction and disease prevention. Weight management programs often have a reduced impact among African American women compared to White women, in part due to interactions between individual, social, and environmental factors. A secondary analysis of focus group data evaluated how cultural elements and contextual factors identified by church-going African American women influence intervention design, approaches for cultural adaptation, and solutions to weight management.

Experiences participating in federal nutrition assistance programs during the early months of the COVID-19 pandemic: an investigation in Vermont.

Background: Federal nutrition assistance programs serve as safety nets for many American households, and participation has been linked to increased food security and, in some instances, improved diet quality and mental health outcomes. The COVID-19 pandemic brought new and increased economic, social, and psychological challenges, necessitating inquiry into how nutrition assistance programs are functioning and associated with public health outcomes.

Methods: Using data from a representative statewide survey administered in Vermont (n = 600) between July and September 2020, we examined participant experiences with major federal nutrition assistance programs: the Supplemental Nutrition Assistance Program (SNAP), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and school meal programs.

Multinational evaluation of genetic diversity indicators for the Kunming-Montreal Global Biodiversity Framework.

Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed, two of which focus on processes contributing to genetic diversity conservation: maintaining genetically distinct populations and ensuring populations are large enough to maintain genetic diversity. The major advantage of these indicators is that they can be estimated with or without DNA-based data.

Diaper need in the United States: A nationally representative study during the COVID-19 pandemic.

Background: Diapers represent a unique financial burden for those with young children. Pre-pandemic, approximately one in three U.S.

Higher rates of food insecurity and stress experienced by food systems workers during the first year of the COVID-19 pandemic.

Introduction: The present study examined the prevalence of food insecurity and perceived stress among food system workers relative to other members of the population during the first year of the COVID-19 pandemic. It also explored perspectives on the role of food system workers during the pandemic and their experiences working during this time.

Methods: Data were collected via an online survey in spring 2021.

Ex situ conservation of two rare oak species using microsatellite and SNP markers.

Plant collections held by botanic gardens and arboreta are key components of ex situ conservation. Maintaining genetic diversity in such collections allows them to be used as resources for supplementing wild populations. However, most recommended minimum sample sizes for sufficient ex situ genetic diversity are based on microsatellite markers, and it remains unknown whether these sample sizes remain valid in light of more recently developed next-generation sequencing (NGS) approaches.

On the benefits of the tryptophan metabolite 3-hydroxyanthranilic acid in Caenorhabditis elegans and mouse aging.

Tryptophan metabolism through the kynurenine pathway influences molecular processes critical to healthy aging including immune signaling, redox homeostasis, and energy production. Aberrant kynurenine metabolism occurs during normal aging and is implicated in many age-associated pathologies including chronic inflammation, atherosclerosis, neurodegeneration, and cancer. We and others previously identified three kynurenine pathway genes-tdo-2, kynu-1, and acsd-1-for which decreasing expression extends lifespan in invertebrates.

Contraception-related knowledge, attitude, belief contexts among US women experiencing homelessness: A scoping review.

Contraception provision may help reduce undesired pregnancies, but women experiencing homelessness may have low health literacy, specific attitudes, and certain beliefs that influence contraception uptake. This scoping review identifies what is known about pregnancy prevention and contraception knowledge, attitudes, and beliefs among US women experiencing homelessness. This review examined English articles that measured the context of knowledge, attitudes, and beliefs related to contraceptive use for avoiding pregnancy among US women experiencing homelessness.

What's theory got to do with it: measuring effects of theory on lifestyle behaviors and weight in the Better Me Within Randomized Trial.

Background: Knowing which theoretical constructs work best to design effective interventions is essential for populations with increased disease burden. African American women (AAW) experience greater prevalence of chronic diseases and fewer benefits from weight loss interventions compared to White women.

Purpose: To examine how theoretical constructs were associated with lifestyle behaviors and weight outcomes in the Better Me Within (BMW) Randomized Trial.

Non-Intentional N-Acetylcysteine Overdose Associated with Cerebral Edema and Brain Death.

N-acetylcysteine is the established treatment for acetaminophen toxicity. This medication's complex dosing schedule engenders a high incidence of medication errors. While nuisance side effects are common, only rare case reports describe serious outcomes associated with N-acetylcysteine administration, all of which take place in the setting of non-intentional N-acetylcysteine overdose.

Implementation of the Texas Community-Engaged Statewide Consortium for the Prevention of COVID-19.

The Community Engagement Alliance (CEAL) Against COVID-19 Disparities aims to conduct community-engaged research and outreach. This paper describes the Texas CEAL Consortium's activities in the first year and evaluates progress. The Texas CEAL Consortium comprised seven projects.

Deliberating enhanced weathering: Public frames, iconic ecosystems and the governance of carbon removal at scale.

Meeting goals for 'net zero' emissions may require the removal of previously emitted carbon dioxide from the atmosphere. One proposal, enhanced rock weathering, aims to speed up the weathering processes of rocks by crushing them finely and spreading them on agricultural land. Public perceptions of enhanced rock weathering and its wider social and environmental implications will be a critical factor determining its potential; we use six 2-day deliberative workshops in England, Wales and Illinois to understand public views.

Assessing ex situ genetic and ecogeographic conservation in a threatened but widespread oak after range-wide collecting effort.

Although the genetic diversity and structure of in situ populations has been investigated in thousands of studies, the genetic composition of ex situ plant populations has rarely been studied. A better understanding of how much genetic diversity is conserved ex situ, how it is distributed among locations (e.g.

Size Doesn't Matter: Integrative Taxonomy Shows and Have Overlapping Shell Sizes and Broadly Concordant Distributions.

AbstractThe calyptraeids and , both direct developers, are abundant in the shallow waters of the northeastern Pacific. They have long been considered as two allopatric species that live on different hosts and differ in body size. In this study, we rigorously test this historical hypothesis by assessing molecular taxonomy, museum records, new morphological and host observations, and population genetic structure along the northeast Pacific coast.

The Texas Community-Engagement Research Alliance Against COVID-19 in Disproportionately Affected Communities (TX CEAL) Consortium.

The coronavirus disease 2019 (COVID-19) pandemic requires urgent implementation of effective community-engaged strategies to enhance education, awareness, and inclusion of underserved communities in prevention, mitigation, and treatment efforts. The Texas Community-Engagement Alliance Consortium was established with support from the United States' National Institutes of Health (NIH) to conduct community-engaged projects in selected geographic locations with a high proportion of medically underserved minority groups with a disproportionate burden of COVID-19 disease and hospitalizations. The purpose of this paper is to describe the development of the Consortium.

Macrophage Migration Inhibitory Factor (MIF) Makes Complex Contributions to Pain-Related Hyperactivity of Nociceptors after Spinal Cord Injury.

Neuropathic pain is a major, inadequately treated challenge for people with spinal cord injury (SCI). While SCI pain mechanisms are often assumed to be in the CNS, rodent studies have revealed mechanistic contributions from primary nociceptors. These neurons become chronically hyperexcitable after SCI, generating ongoing electrical activity that promotes ongoing pain.

Adult-Attained Height and Colorectal Cancer Risk: A Cohort Study, Systematic Review, and Meta-Analysis.
