In vivo base editing extends lifespan of a humanized mouse model of prion disease.

Prion disease is a fatal neurodegenerative disease caused by the misfolding of prion protein (PrP) encoded by the PRNP gene. While there is currently no cure for the disease, depleting PrP in the brain is an established strategy to prevent or stall templated misfolding of PrP. Here we developed in vivo cytosine and adenine base strategies delivered by adeno-associated viruses to permanently modify the PRNP locus to achieve PrP knockdown in the mouse brain.

Catheter Tip Migration in Female Patients With Breast Cancer: A Retrospective Comparative Study of Right- and Left-Sided Chest Ports.

Chest ports are typically inserted via the right internal jugular vein with the left side being utilized in certain patient populations. The purpose of this study was to evaluate the dynamic position of the chest port and catheter tip, comparing a demographically matched cohort of female breast cancer patients with right- or left-sided chest ports. 142 female patients with breast cancer requiring chest port insertion for chemotherapy and imaging confirming catheter tip position initially with supine fluoroscopy and follow-up with erect chest radiography over a 5-year period were identified.

Grain engineering for efficient near-infrared perovskite light-emitting diodes.

Metal halide perovskites show promise for next-generation light-emitting diodes, particularly in the near-infrared range, where they outperform organic and quantum-dot counterparts. However, they still fall short of costly III-V semiconductor devices, which achieve external quantum efficiencies above 30% with high brightness. Among several factors, controlling grain growth and nanoscale morphology is crucial for further enhancing device performance.

'The upside-down' healthcare professional students' experiences of delirium: an all-Ireland focus group study.

Background: Delirium is a complex neuropsychiatric syndrome characterised by an acute state of confusion, with a substantial impact on medical inpatients. Despite its growing recognition as a global healthcare concern, delirium remains underdiagnosed, partly due to a lack of awareness among healthcare professionals. The aim of this study was to explore how healthcare professional students experience caring for individuals experiencing delirium, the influence of their current pre-registration healthcare education, and importance of interprofessional teamwork in their role.

Embolisation of an acquired uterine arteriovenous malformation.

A G5P2+2 woman in her 30s presented to hospital with per vaginum (PV) bleeding, approximately 2 weeks post electric vacuum aspiration (EVA) for retained products of conception. Ultrasound and MRI demonstrated a large vascular myometrial lesion, suggestive of a uterine arteriovenous malformation (UAVM). She underwent digital subtraction angiography (DSA) with interventional radiology and simultaneous uterine artery embolisation (UAE).

The ClinGen Syndromic Disorders Gene Curation Expert Panel: Assessing the Clinical Validity of 111 Gene-Disease Relationships.

Purpose: The Clinical Genome Resource (ClinGen) Gene Curation Expert Panels (GCEPs) have historically focused on specific organ systems or phenotypes; thus, the ClinGen Syndromic Disorders GCEP (SD-GCEP) was formed to address an unmet need.

Methods: The SD-GCEP applied ClinGen's framework to evaluate the clinical validity of genes associated with rare syndromic disorders. 111 Gene-Disease Relationships (GDRs) associated with 100 genes spanning the clinical spectrum of syndromic disorders were curated.

Impact of low FODMAP sourdough bread on gut microbiota using an colonic fermentation model.

This study explores the development of whole-grain sourdough bread with reduced FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) content to offer dietary solutions for individuals with irritable bowel syndrome (IBS). Three sourdough breads were prepared using different lactic acid bacteria (LAB) strains including FST1.7 (SD-FST1.

Nurses' experiences of working with robotic assisted surgery in an Irish healthcare setting: A qualitative descriptive design.

Aim: To explore the experiences of nurses working with robotic assisted surgery patients.

Background: Robotic assisted surgery has grown considerably since its introduction in the 1980's with more than 6500 da Vinci robots installed worldwide and over 55,000 surgeons trained to use these machines. Nurses play a major role in the successful completion of robotic surgery; however, minimal research has been conducted in the literature to date surrounding robotic assisted surgery nurses' experiences working in the perioperative department and beyond.

A Pyrrole Modified 3,4-Propylenedioxythiophene Conjugated Polymer as Hole Transport Layer for Efficient and Stable Perovskite Solar Cells.

Despite the outstanding electric properties and cost-effectiveness of poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives, their performance as hole transport layer (HTL) materials in conventional perovskite solar cells (PSCs) has lagged behind that of widely used spirobifluorene-based molecules or poly(triaryl amine). This gap is mainly from their poor solubility and energy alignment mismatch. In this work, the design and synthesis of a pyrrole-modified HTL (PPr) based on 3,4-propylenedioxythiophene (ProDOT) are presented for efficient and stable PSCs.

Distinct Longitudinal Changes in EEG Measures Reflecting Functional Network Disruption in ALS Cognitive Phenotypes.

Amyotrophic lateral sclerosis (ALS) is characterised primarily by motor system degeneration, with clinical evidence of cognitive and behavioural change in up to 50% of cases. We have shown previously that resting-state EEG captures dysfunction in motor and cognitive networks in ALS. However, the longitudinal development of these dysfunctional patterns, especially in networks linked with cognitive-behavioural functions, remains unclear.

Two-dimensional-lattice-confined single-molecule-like aggregates.

Intermolecular distance largely determines the optoelectronic properties of organic matter. Conventional organic luminescent molecules are commonly used either as aggregates or as single molecules that are diluted in a foreigner matrix. They have garnered great research interest in recent decades for a variety of applications, including light-emitting diodes, lasers and quantum technologies, among others.

CRISPR Screening of Transcribed Super-Enhancers Identifies Drivers of Triple-Negative Breast Cancer Progression.

Triple-negative breast cancer (TNBC) is the most therapeutically recalcitrant form of breast cancer, which is due in part to the paucity of targeted therapies. A systematic analysis of regulatory elements that extend beyond protein-coding genes could uncover avenues for therapeutic intervention. To this end, we analyzed the regulatory mechanisms of TNBC-specific transcriptional enhancers together with their noncoding enhancer RNA (eRNA) transcripts.

Changing the food environment in secondary school canteens to promote healthy dietary choices: a qualitative study with school caterers.

Background: Typical adolescent diets do not meet current dietary recommendations. There is a need to address these dietary patterns to reduce the risk of obesity and other diet-related diseases. Schools provide an opportune setting to do so, as students consume a substantial proportion of their daily dietary intake whilst at school.

Digital education about delirium for health care professional students: a mixed methods systematic review.

Background: Competence in delirium care begins with pre-registration education for health care professionals. Although a common complication for hospitalised patients, delirium is avoidable and reversible. Delirium requires early recognition in person-centred care.

Co-design and mixed methods evaluation of an interdisciplinary digital resource for undergraduate health profession students to improve the prevention, recognition, and management of delirium in Ireland: a study protocol.

Background: Delirium is a common symptom of acute illness which is potentially avoidable with early recognition and intervention. Despite being a growing concern globally, delirium remains underdiagnosed and poorly reported, with limited understanding of effective delirium education for undergraduate health profession students. Digital resources could be an effective approach to improving professional knowledge of delirium, but studies utilising these with more than one profession are limited, and no evidence-based, interdisciplinary, digital delirium education resources are reported.

Inhibition of Clinical MRSA Isolates by Coagulase Negative Staphylococci of Human Origin.

is frequently highlighted as a priority for novel drug research due to its pathogenicity and ability to develop antibiotic resistance. Coagulase-negative staphylococci (CoNS) are resident flora of the skin and nares. Previous studies have confirmed their ability to kill and prevent colonization by through the production of bioactive substances.

Effectiveness of workplace interventions with digital elements to reduce sedentary behaviours in office employees: a systematic review and meta-analysis.

Background: Digital interventions are potential tools for reducing and limiting occupational sedentary behaviour (SB) in sedentary desk-based jobs. Given the harmful effects of sitting too much and sitting for too long while working, the aim of this systematic review and meta-analysis was to examine the effectiveness of workplace interventions, that incorporated digital elements, to reduce the time spent in SB in office workers.

Methods: Randomised control trials that evaluated the implementation of workplace interventions that incorporated digital elements for breaking and limiting SB among desk-based jobs were identified by literature searches in six electronic databases (PubMed, Web of Science, Scopus, CINAHL, PsycINFO and PEDro) published up to 2023.
