Trends, challenges, and research pathways in emerging contaminants: a comprehensive bibliometric analysis.

Integr Environ Assess Manag

January 2025

Department of Civil and Environmental Engineering, Florida State University, Tallahassee, FL, United States.

The growing concern over environmental pollution has spurred extensive research into various contaminants impacting ecosystems and human health. Emerging contaminants (ECs), including pharmaceuticals, personal care products, endocrine-disrupting chemicals, nanomaterials, and microplastics, have garnered significant attention due to their persistence, bioaccumulation, and toxicity. This study presents a comprehensive bibliometric analysis of EC research, aiming to detail the research landscape, highlight significant contributions, and identify influential researchers and pivotal studies.

Colorectal cancer (CRC) remains a major global health burden, being one of the most prevalent cancers with high mortality rates. Despite advances in conventional treatment modalities, patients with metastatic CRC often face limited options and poor outcomes. Chimeric antigen receptor-T (CAR-T) cell therapy, initially successful in hematologic malignancies, presents a promising avenue for treating solid tumors, including CRC.

The glucocorticoid receptor (GR) is present in almost every vertebrate cell and is utilized in many biological processes. Despite an abundance of mammalian data, the structural conservation of the receptor and cross-species susceptibility, particularly for aquatic species, has not been well defined. Efforts to reduce, refine, and/or replace animal testing have increased, driving the impetus to advance development of new approach methodologies (NAMs).

Astrocytes critically shape whole-brain structure and function by forming extensive gap junctional networks that intimately and actively interact with neurons. Despite their importance, existing computational models of whole-brain activity ignore the roles of astrocytes while primarily focusing on neurons. Addressing this oversight, we introduce a biophysical neural mass network model, designed to capture the dynamic interplay between astrocytes and neurons via glutamatergic and GABAergic transmission pathways.

Temporal constructs are central to reproduction and kinship, as epitomised by the pervasive concept of the biological clock within public imaginaries. While queer scholarship has problematised linear models of kinship and reproductive temporality, the specific temporalities associated with donor-conceived families have received less scholarly attention, despite the increasing prevalence of these family structures. In this article, we explore the question: how does donor conception reconfigure temporal logics.

Importance: Cell and gene therapies are revolutionizing the treatment landscape for children and adults with rare diseases and can be life-changing for patients and their families. Successful implementation of these new therapies into clinical practice depends on their accessibility and affordability, particularly through publicly funded Medicaid agencies, which cover many children and adults with rare diseases.

Objective: To provide a framework to broadly assess cell and gene therapies, evaluate payment options, and ensure equitable access through the lens of publicly funded Medicaid programs.

Background: Several health care networks have fully adopted second-generation supraglottic airway (SGA) i-gel. Real-world evidence of enhanced patient safety after such practice change is lacking. We hypothesized that the implementation of i-gel compared to the previous LMA®-Unique™ would be associated with a lower risk of airway-related safety events.

Background And Objectives: This systematic review aims to synthesize the current literature on the association between chemotherapy (CTX) and chemotherapy-related cognitive impairment (CRCI) with functional and structural brain alterations in patients with noncentral nervous system cancers.

Methods: A comprehensive search of the PubMed/MEDLINE, Web of Science, and Embase databases was conducted, and results were reported following preferred reporting items for systematic review and meta-analyses guidelines. Data on study design, comparison cohort characteristics, patient demographics, cancer type, CTX agents, neuroimaging methods, structural and functional connectivity (FC) changes, and cognitive/psychological assessments in adult patients were extracted and reported.

Polycythemia vera (PV) is characterized by clonal hematopoietic stem or progenitor cells with constitutively active somatic mutation(s) in the Janus kinase 2 gene. Phlebotomy (Phl) and aspirin are often used alone for low-risk PV patients. However, data from the Low-PV study demonstrated that Phl and aspirin may not be adequate for patients.

Purpose: Despite robust quality improvement efforts in healthcare, learning from patient safety incidents remains difficult. Our study explores counter-vailing powers shaping learning processes and possibilities in healthcare organizations, with a focus on social, political and organizational dynamics of learning.

Design/methodology/approach: Deploying concepts of situated curriculum, boundary work and interconnected knowledge practices, we interviewed staff and physicians ( = 15) in a large Academic Health Science Centre in Canada about their experiences of incident investigations and resultant information sharing.

Staining brain slices with acetoxymethyl ester (AM) Ca dyes is a straightforward procedure to load multiple cells, and Fluo-4 is a commonly used high-affinity indicator due to its very large dynamic range. It has been shown that this dye preferentially stains glial cells, providing slow and large Ca transients, but it is questionable whether and at which temporal resolution it can also report Ca transients from neuronal cells. Here, by electrically stimulating mouse hippocampal slices, we resolved fast neuronal signals corresponding to 1%-3% maximal fluorescence changes.

Objective: The Pediatric Emergency Care Applied Research Network (PECARN) derived and externally validated a clinical prediction rule to identify children with blunt torso trauma at low risk for intraabdominal injuries undergoing acute intervention (IAI). Little is known about the risk for IAI when only one or two prediction rule variables are positive. We sought to determine the risk for IAI when either one or two PECARN intraabdominal injury rule variables are positive.

A fundamental issue in neuroscience is a lack of understanding regarding the relationship between brain function and the white matter architecture that supports it. Individuals with chronic neuropathic pain (NP) exhibit functional abnormalities throughout brain networks collectively termed the "dynamic pain connectome" (DPC), including the default mode network (DMN), salience network, and ascending nociceptive and descending pain modulation systems. These functional abnormalities are often observed in a sex-dependent fashion.

Blood-contacting medical devices, especially extracorporeal membrane oxygenators (ECMOs), are highly susceptible to surface-induced coagulation because of their extensive surface area. This can compromise device functionality and lead to life-threatening complications. High doses of anticoagulants, combined with anti-thrombogenic surface coatings, are typically employed to mitigate this risk, but such treatment can lead to hemorrhagic complications.

Am J Reprod Immunol

January 2025

State Key Laboratory of Reproductive Medicine and Offspring Health, Center for Reproductive Medicine, Institute of Women, Children and Reproductive Health, Shandong University, Jinan, Shandong, China.

Background: Alterations in lipid metabolism were reported to impact human fertility; however, there is limited evidence on the association of lipid metabolism with embryo implantation as well as the etiology of recurrent implantation failure (RIF), especially regarding arachidonic acid metabolism.

Methods: Experimental verification research (16 RIF patients and 30 control patients) based on GEO database analysis (24 RIF patients and 24 control patients). The methods in bioinformatics included differential gene screening, functional enrichment analysis, protein-protein interaction network, cluster analysis, weighted gene co-expression network analysis, and so forth.
