A protocol for stakeholder engagement in head and neck cancer pragmatic trials.

Meaningful engagement with stakeholders in research demands intentional approaches. This paper describes the development of a framework to guide stakeholder engagement as research partners in a pragmatic trial proposed to evaluate behavioral interventions for dysphagia in head and neck cancer patients. We highlight the core principles of stakeholder engagement including representation of all perspectives, meaningful participation, respectful partnership with stakeholders, and accountability to stakeholders; and describe how these principles were operationalized to engage relevant stakeholders throughout the course of a large clinical trial.

Cytomegalovirus Post-Prophylaxis Surveillance in High-Risk Kidney and Liver Recipients Prevents CMV End-Organ Disease and Ganciclovir-Resistance.

Purpose: Evaluate cytomegalovirus (CMV) post-prophylaxis surveillance in high-risk (D+/R-) kidney and liver transplant recipients.

Methods: Adult D+/R- patients were included if transplanted between 6/1/15 and 11/30/22 and divided into a pre-CMV-stewardship-era (6/1/15-5/31/18), CMV-stewardship-era (6/1/18-6/30/20), and a surveillance-era (7/1/2020-11/30/2022) then followed through 12 months. The primary objective was to evaluate CMV-related outcomes.

Alzheimer's disease genetic risk and changes in brain atrophy and white matter hyperintensities in cognitively unimpaired adults.

Reduced brain volumes and more prominent white matter hyperintensities on MRI scans are commonly observed among older adults without cognitive impairment. However, it remains unclear whether rates of change in these measures among cognitively normal adults differ as a function of genetic risk for late-onset Alzheimer's disease, including -ɛ4, -ɛ2 and Alzheimer's disease polygenic risk scores (AD-PRS), and whether these relationships are influenced by other variables. This longitudinal study examined the trajectories of regional brain volumes and white matter hyperintensities in relationship to genotypes ( = 1541) and AD-PRS ( = 1093) in a harmonized dataset of middle-aged and older individuals with normal cognition at baseline (mean baseline age = 66 years, SD = 9.

Investigating the In Vivo Biodistribution of Extracellular Vesicles Isolated from Various Human Cell Sources Using Positron Emission Tomography.

Positron emission tomography (PET) is a powerful tool for investigating the in vivo behavior of drug delivery systems. We aimed to assess the biodistribution of extracellular vesicles (EVs), nanosized vesicles secreted by cells isolated from various human cell sources using PET. EVs were isolated from mesenchymal stromal cells (MSCs) (MSC EVs), human macrophages (Mϕ EVs), and a melanoma cell line (A375 EVs) by centrifugation and were conjugated with deferoxamine for radiolabeling with Zr-89.

The Roles of Ovarian-Adnexal Reporting and Data System US and Ovarian-Adnexal Reporting and Data System MRI in the Evaluation of Adnexal Lesions.

The Ovarian-Adnexal Reporting and Data System (O-RADS) is an evidence-based clinical support system for ovarian and adnexal lesion assessment in women of average risk. The system has both US and MRI components with separate but complementary lexicons and assessment categories to assign the risk of malignancy. US is an appropriate initial imaging modality, and O-RADS US can accurately help to characterize most adnexal lesions.

Interactions between eosinophils and IL-5Rα-positive mast cells in nonadvanced systemic mastocytosis.

Background: Bidirectional interactions between eosinophils and mast cells (MCs) have been reported in various allergic diseases. Bone marrow (BM) eosinophilia, and to a lesser extent blood eosinophilia, is common in systemic mastocytosis (SM), but its significance remains unknown.

Objective: We described blood and BM eosinophil characteristics in SM.

Advanced Abdominal Aortic Aneurysm Modeling in Mice by Combination of Topical Elastase and Oral ß-aminopropionitrile.

The topical elastase murine model of abdominal aortic aneurysm (AAA) is enhanced when combined with ß-aminopropionitrile (BAPN)-supplemented drinking water to reliably produce true infrarenal aneurysms with behaviors that mimic human AAAs. Topically applying elastase to the adventitia of the infrarenal aorta causes structural damage to the elastic layers of the aortic wall and initiates aneurysmal dilation. Co-administering BAPN, a lysyl oxidase inhibitor, promotes sustained wall degeneration by reducing collagen and elastin crosslinking.

Perinatal Airway Management Mandibular Anomalies: A National Inpatient Cohort Analysis.

Objective: To characterize incidence of mandibular anomalies (MAs) and compare gestational age, airway interventions, and complications among individuals with MA phenotypes (isolated retrognathia, isolated micrognathia, syndromic micrognathia, micrognathia plus cleft palate/cleft lip and palate, agnathia/micrognathia plus cervical auricle/otocephaly, and agnathia/micrognathia plus microstomia) and unaffected individuals.

Methods: The Healthcare Cost and Utilization Project Kids' Inpatient Database was used to collect data over a 20-year period beginning in 2000. Interventions were classified as perinatal when performed on day of life (DOL) 0 or 1 and subsequent when performed during the birth hospitalization after DOL 1.

Biological effects of sodium phenylbutyrate and taurursodiol in Alzheimer's disease.

Introduction: Sodium phenylbutyrate and taurursodiol (PB and TURSO) is hypothesized to mitigate endoplasmic reticulum stress and mitochondrial dysfunction, two of many mechanisms implicated in Alzheimer's disease (AD) pathophysiology.

Methods: The first-in-indication phase 2a PEGASUS trial was designed to gain insight into PB and TURSO effects on mechanistic targets of engagement and disease biology in AD. The primary clinical efficacy outcome was a global statistical test combining three endpoints relevant to disease trajectory (cognition [Mild/Moderate Alzheimer's Disease Composite Score], function [Functional Activities Questionnaire], and total hippocampal volume on magnetic resonance imaging).

Cervical cancer: a new era.

Cervical cancer is a major global health issue, ranking as the fourth most common cancer in women worldwide. Depending on stage, histology, and patient factors, the standard management of cervical cancer is a combination of treatment approaches, including (fertility- or non-fertility-sparing) surgery, radiotherapy, platinum-based chemotherapy, and novel systemic therapies such as bevacizumab, immune checkpoint inhibitors, and antibody-drug conjugates. While ambitious global initiatives seek to eliminate cervical cancer as a public health problem, the management of cervical cancer continues to evolve with major advances in imaging modalities, surgical approaches, identification of histopathological risk factors, radiotherapy techniques, and biomarker-driven personalized therapies.

The neonatal Fc receptor (FcRn) is a pan-arterivirus receptor.

Arteriviruses infect a variety of mammalian hosts, but the receptors used by these viruses to enter cells are poorly understood. We identified the neonatal Fc receptor (FcRn) as an important pro-viral host factor via comparative genome-wide CRISPR-knockout screens with multiple arteriviruses. Using a panel of cell lines and divergent arteriviruses, we demonstrate that FcRn is required for the entry step of arterivirus infection and serves as a molecular barrier to arterivirus cross-species infection.

Higher Rates of Certain Autoimmune Diseases in Transgender and Gender Diverse Youth.

Purpose: The objective of this study is to determine the prevalence of certain autoimmune diseases in transgender and gender diverse (TGD) youth.

Methods: A multicenter, retrospective analysis was conducted from January 2013 to January 2019 of youth ≤26 years of age with concurrent diagnoses of gender dysphoria (GD) and at least one of the studied autoimmune diseases. Prevalence rates were calculated and compared to previously reported rates.

Development of international consensus on a standardised image acquisition protocol for diagnostic evaluation of the sacroiliac joints by MRI: an ASAS-SPARTAN collaboration.

Background: A range of sacroiliac joint (SIJ) MRI protocols are used in clinical practice but not all were specifically designed for diagnostic ascertainment. This can be confusing and no standard diagnostic SIJ MRI protocol is currently accepted worldwide.

Objective: To develop a standardised MRI image acquisition protocol (IAP) for diagnostic ascertainment of sacroiliitis.

CALMER Conflict: A Novel Curriculum for Graduating Medical Students to Manage and Defuse Patient-Provider Conflict.

Background: Workplace violence disproportionately affects healthcare workers and verbal aggression from patients frequently occurs. While verbal de-escalation is the first-line approach to defusing anger, there is a lack of consistent curricula or robust evaluation in undergraduate medical education.

Aim: To develop a medical school curriculum focused on de-escalation skills for adult patients and evaluate effectiveness with surveys and an objective structured clinical examination (OSCE).

Methodological Considerations in Evaluating Breast Cancer Screening Studies.

In evidence-based medicine frameworks, the highest level of evidence is derived from quantitative synthesis of double-masked, high-quality, randomly assigned controlled trials. Meta-analyses of randomly assigned controlled trials have demonstrated that screening mammography reduces breast cancer deaths. In the United States, every major guideline-producing organization has recommended screening mammography in average-risk women; however, there are controversies about age and frequency.

Identification of Host Proteins Involved in Hepatitis B Virus Genome Packaging.

A critical part of the hepatitis B virus (HBV) life cycle is the packaging of the pregenomic RNA (pgRNA) into nucleocapsids. While this process is known to involve several viral elements, much less is known about the identities and roles of host proteins in this process. To better understand the role of host proteins, we isolated pgRNA and characterized its protein interactome in cells expressing either packaging-competent or packaging-incompetent HBV genomes.

Temporally resolved early bone morphogenetic protein-driven transcriptional cascade during human amnion specification.

Amniogenesis, a process critical for continuation of healthy pregnancy, is triggered in a collection of pluripotent epiblast cells as the human embryo implants. Previous studies have established that bone morphogenetic protein (BMP) signaling is a major driver of this lineage specifying process, but the downstream BMP-dependent transcriptional networks that lead to successful amniogenesis remain to be identified. This is, in part, due to the current lack of a robust and reproducible model system that enables mechanistic investigations exclusively into amniogenesis.
