Background: One factor considered essential to successful implementation is organizational readiness. The purpose of this study was to explore ways to improve the measurement of organizational readiness, and in particular to refine a preliminary measure based on the Readiness = Motivation x innovation Specific Capacity x General Capacity (R = MC2) heuristic. We assessed the experiences of staff in Federally Qualified Health Centers (FQHC) implementing evidence-based interventions (EBIs) designed to increase colorectal cancer screening (CRCS) who previously completed the survey and aimed to understand their perspectives on why our data were positively skewed.

In low- and middle-income countries (LMICs), barriers such as low system readiness, contextual mismatches, and resource limitations impede effective implementation of evidence-based interventions. This commentary offers insights into overcoming these challenges with a case study of the PRISM project, designed to reduce behavioral and psychological symptoms of dementia in older adults living in Thailand. The case highlights how combining two evidence-based models - the clinical intervention and the implementation science process enhances program success.

The vaginal microbiome's role in risk, progression, and treatment of female cancers has been widely explored. Yet, there remains a need to develop methods to understand the interaction of microbiome factors with host cells and to characterize their potential therapeutic functions. To address this challenge, we developed a systems biology framework we term the Pharmacobiome for microbiome pharmacology analysis.

Food insecurity may predict poorer body image, which is associated with increased risk of mental health problems. However, minimal attention has been given to the food insecurity-body image link and to factors that may influence this link, such as assigned sex; importantly, females are more likely to experience both food insecurity and body dissatisfaction. The present study used data from the 2017 to 2018 Canadian Community Health Survey ( = 32,017) to investigate the effects of food insecurity and sex on body satisfaction via generalized ordered logistic regression.

Astrocytes express ionotropic receptors, including N-methyl-D-aspartate receptors (NMDARs). However, the contribution of NMDARs to astrocyte-neuron interactions, particularly in vivo, has not been elucidated. Here we show that a knockdown approach to selectively reduce NMDARs in mouse cortical astrocytes decreases astrocyte Ca transients evoked by sensory stimulation.

While the Department of Defense (DoD) has given increased attention and priority to preventing sexual assault and sexual harassment (SA/SH), it remains a problem. To build its prevention capacity, DoD piloted Getting To Outcomes (GTO) from 2019 to 2022 at 10 military installations. GTO is an evidence-based planning and implementation support that has been used in many civilian contexts but has only recently been adapted for military SA/SH.

Article Synopsis
  • Cervicovaginal inflammation can lead to serious reproductive health issues like HIV acquisition and cervical cancer, but its relationship with the vaginal microbiome remains underexplored.
  • This study analyzed samples from 43 Canadian women to uncover the links between inflammation and changes in the microbiome, identifying lower levels of beneficial bacteria (L. crispatus) and higher levels of immune cells (APCs) in inflamed samples.
  • Findings suggested that inflammation affects bacterial metabolism and immune protein levels, indicating a need for further research on how these factors might impact reproductive health, including HIV transmission and cancer risk.

Bacterial vaginosis (BV) is characterized by depletion of Lactobacillus and overgrowth of anaerobic and facultative bacteria, leading to increased mucosal inflammation, epithelial disruption, and poor reproductive health outcomes. However, the molecular mediators contributing to vaginal epithelial dysfunction are poorly understood. Here we utilize proteomic, transcriptomic, and metabolomic analyses to characterize biological features underlying BV in 405 African women and explore functional mechanisms in vitro.

Neutrophil recruitment and activation within the female genital tract are often associated with tissue inflammation, loss of vaginal epithelial barrier integrity, and increased risk for sexually transmitted infections, such as HIV-1. However, the direct role of neutrophils on vaginal epithelial barrier function during genital inflammation in vivo remains unclear. Using complementary proteome and immunological analyses, we show high neutrophil influx into the lower female genital tract in response to physiological surges in progesterone, stimulating distinct stromal, immunological, and metabolic signaling pathways.

Implementing evidence-based interventions remains slow in federally qualified health centers (FQHCs). The purpose of this study is to qualitatively examine the R = MC (Readiness = motivation × innovation specific capacity × general capacity) heuristic subcomponents in the context of implementing general and colorectal cancer screening (CRCS)-related practice changes in FQHCs. We conducted 17 interviews with FQHC employees to examine (1) experiences with successful or unsuccessful practice change efforts, (2) using approaches to promote CRCS, and (3) opinions about R = MC subcomponents.

Shiga toxins (Stxs) produced by ingested can induce hemolytic uremic syndrome after crossing the intact intestinal barrier, entering the bloodstream, and targeting endothelial cells in the kidney. The method(s) by which the toxins reach the bloodstream are not fully defined. Here, we used two polarized cell models to evaluate Stx translocation: (i) a single-layer primary colonic epithelial cell model and (ii) a three-cell-layer model with colonic epithelial cells, myofibroblasts, and colonic endothelial cells.

Background: Organizational readiness is a key factor for successful implementation of evidence-based interventions (EBIs), but a valid and reliable measure to assess readiness across contexts and settings is needed. The R = MC heuristic posits that organizational readiness stems from an organization's motivation, capacity to implement a specific innovation, and its general capacity. This paper describes a process used to examine the face and content validity of items in a readiness survey developed to assess organizational readiness (based on R = MC) among federally qualified health centers (FQHC) implementing colorectal cancer screening (CRCS) EBIs.

Accruing evidence reveals best practices for how to help individuals living with Sickle Cell Disease (SCD); yet, the implementation of these evidence-based practices in healthcare settings is lacking. The Sickle Cell Disease Implementation Consortium (SCDIC) is a national consortium that uses implementation science to identify and address barriers to care in SCD. The SCDIC seeks to understand how and why patients become unaffiliated from care and determine strategies to identify and connect patients to care.

Organizational readiness is essential for high-quality implementation of innovations (programs, policies, practices, or processes). The = MC heuristic describes three readiness components necessary for implementation-the general functioning of the organization (general capacities), the ability to deliver a particular innovation (innovation-specific capacities), and the motivation to implement the innovation. In this article, we describe how we used the for assessing, prioritizing, and improving readiness and , a systematic process for planning implementation strategies, to build organizational readiness for implementation of sexual assault prevention evidence-based interventions (EBIs).

Sexual violence affects millions of Americans, and approximately one out of every three women and one out of every four men have experienced sexual violence during their lifetime. While prevention efforts have focused on implementing specific programmatic approaches, there has been relatively little focus on developing comprehensive and effective approaches to reduce sexual assault prevention across an organization. This study describes the development of the Prevention Evaluation Framework, an assessment targeting organizational best practices for comprehensive sexual assault prevention across multiple domains including human resources, collaborative relationships and infrastructure, use of evidence-informed approaches, quality implementation and continuous evaluation of programs/policies.

Background: The microbiota of the lower female genital tract plays an important role in women's health. Microbial profiling using the chaperonin60 (cpn60) universal target (UT) improves resolution of vaginal species associated with negative health outcomes compared to the more commonly used 16S ribosomal DNA target. However, the choice of DNA extraction and PCR product purification methods may bias sequencing-based microbial studies and should be optimized for the sample type and molecular target used.

Now more than ever, the lack of racial and ethnic diversity must be addressed within the health care system, specifically in occupational therapy. This change starts with the successful completion of educational programs by underrepresented minority (URM) occupational therapy students. To increase diversity in the profession, accrediting bodies should mandate support for students of all backgrounds to be successful in higher education.

Whole slide imaging (WSI) scanners produce tissue slide images with a large field of view and a high resolution for pathologists to use in diagnoses. Color performance tests of these color imaging devices are necessary and can use stained tissue slides if the color truth is established using a hyperspectral imaging microscopy system (HIMS). The purpose of this study was to estimate the reproducibility uncertainty of CIELAB coordinates for a reference tissue slide measured by both the HIMS and a WSI scanner.

An important goal of personalized medicine is to identify heterogeneity in treatment effects and then use that heterogeneity to target the intervention to those most likely to benefit. Heterogeneity is assessed using the predicted individual treatment effects framework, and a permutation test is proposed to establish if significant heterogeneity is present given the covariates and predictive model or algorithm used for predicted individual treatment effects. We first show evidence for heterogeneity in the effects of treatment across an illustrative example data set.
