The Loss of the Nurse as an Individual: Nursing, Well-Being and Existentialism.

Research into how existentially aware nurses and nursing interventions have highlighted the benefits to patients and patient outcomes. Less is known about how existentially based training affects nurses themselves. This project sought to understand if and how a training programme developed to improve nurses' knowledge of existential theory would affect their well-being.

Group B Streptococcal Membrane Vesicles Induce Proinflammatory Cytokine Production and Are Sensed in an NLRP3 Inflammasome-Dependent Mechanism in a Human Macrophage-like Cell Line.

Group B (GBS) is a major cause of fetal and neonatal mortality worldwide. Many of the adverse effects of invasive GBS are associated with inflammation; therefore, understanding bacterial factors that promote inflammation is of critical importance. Membrane vesicles (MVs), which are produced by many bacteria, may modulate host inflammatory responses.

De Novo Hypercalcaemia in a Patient With Chronic Hypoparathyroidism.

Calcium Homeostasis in the human body is regulated by hormones, including parathyroid hormone and vitamin D3. Dysfunction in the form of hypoparathyroidism causes hypocalcaemia. In patients treated for primary hypoparathyroidism with activated vitamin D replacement, iatrogenic hypercalcaemia can occur.

Structured pre-delivery huddles enhance confidence in managing newborns with critical congenital heart disease in the delivery room.

Background: Newborns with critical congenital heart disease (CCHD) require specialized delivery room management, but varying experience and knowledge can reduce confidence and impact care.

Methods: A pre-delivery, structured huddle checklist was introduced, addressing team roles, expected physiology, and management plans. PDSA cycles incorporated guidelines and simulation-based education to improve confidence in specialized resuscitation strategies.

Evaluating the use of 3D skin models as simulation-based educational tools among nursing students: A quasi-experimental study.

Background: Teaching dermatology is challenging because of its' highly visible and tactile nature. While images improve visual memory and are valuable teaching aids, even high-quality photographs have limitations in what they can convey.

Aim: Our aim is to validate the use of silicone-based 3D skin models as simulation-based educational tools by assessing their impact on recognition of various skin conditions among nursing students.

Selection of antibiotic-resistant bacterial populations in the dairy cow gut following intramuscular ceftiofur treatment for metritis.

Third-generation cephalosporins such as ceftiofur are critically important antibiotics because human pathogens with resistance to these drugs contribute to high mortality rates. These antibiotics are also frequently given to dairy cattle for treating infections, emphasizing the critical role they play in both human and veterinary medicine. To investigate the effect of intramuscular ceftiofur treatment on the concentration of resistant bacteria in the gut, we focused on cows with metritis, a common bacterial infection that frequently requires antibiotic intervention.

GPTs are GPTs: Labor market impact potential of LLMs.

Research is needed to estimate how jobs may be affected.

Untargeted metabolomics and metagenomics reveal signatures for intramammary ceftiofur treatment and lactation stage in the cattle hindgut.

The gut microbiota in cattle is essential for protein, energy, and vitamin production and hence, microbiota perturbations can affect cattle performance. This study evaluated the effect of intramammary (IMM) ceftiofur treatment and lactation stage on the functional gut microbiome and metabolome. Forty dairy cows were enrolled at dry-off.

Shifts in the functional capacity and metabolite composition of the gut microbiome during recovery from enteric infection.

While enteric pathogens have been widely studied for their roles in causing foodborne infection, their impacts on the gut microbial community have yet to be fully characterized. Previous work has identified notable changes in the gut microbiome related to pathogen invasion, both taxonomically and genetically. Characterization of the metabolic landscape during and after enteric infection, however, has not been explored.

The Associations between Snack Intake and Cariogenic Oral Microorganism Colonization in Young Children of a Low Socioeconomic Status.

Cariogenic microorganisms are crucial pathogens contributing to the development of early childhood caries. Snacks provide fermentable carbohydrates, altering oral pH levels and potentially affecting microorganism colonization. However, the relationship between snack intake and cariogenic microorganisms like and in young children is still unclear.

The Drosophila Hippo pathway transcription factor Scalloped and its co-factors alter each other's chromatin binding dynamics and transcription in vivo.

The Hippo pathway is an important regulator of organ growth and cell fate. The major mechanism by which Hippo is known to control transcription is by dictating the nucleo-cytoplasmic shuttling rate of Yorkie, a transcription co-activator, which promotes transcription with the DNA binding protein Scalloped. The nuclear biophysical behavior of Yorkie and Scalloped, and whether this is regulated by the Hippo pathway, remains unexplored.

Improving connections to early childhood systems of care via a universal home visiting program in Massachusetts.

Welcome Family is a universal, short-term nurse home visiting program designed to promote optimal maternal and infant physical and mental well-being and provide an entry point into the early childhood system of care to all families with newborns up to 8 weeks old living in defined communities in Massachusetts. The present study examines whether: 1) Welcome Family meets its goal of successfully connecting families to two early childhood programs-evidence-based home visiting (EBHV) and early intervention (EI)-relative to families with similar background experiences who do not participate in Welcome Family, and 2) whether these impacts are conditional on families' race and ethnicity and their primary language-two characteristics that are related to structural racism and health inequities. The study used coarsened exact matching (CEM) based on birth certificate data to match Welcome Family participants who enrolled during 2013-2017 to mothers and their infants living in the home visiting catchment areas who did not receive home visiting during the study period.

Intrapartum antibiotic prophylaxis selects for mutators in group B streptococci among persistently colonized patients.

Through vaginal colonization, GBS causes severe pregnancy outcomes including neonatal sepsis and meningitis. Although intrapartum antibiotic prophylaxis (IAP) has reduced early-onset disease rates, persistent GBS colonization has been observed in patients following prophylaxis. To determine whether IAP selects for genomic signatures that enhance GBS survival and persistence in the vaginal tract, whole-genome sequencing was performed on 97 isolates from 58 patients before (prenatal) and after (postpartum) IAP/childbirth.

Patient Perspectives on the Use of Artificial Intelligence in Health Care: A Scoping Review.

Purpose: Artificial intelligence (AI) technology is being rapidly adopted into many different branches of medicine. Although research has started to highlight the impact of AI on health care, the focus on patient perspectives of AI is scarce. This scoping review aimed to explore the literature on adult patients' perspectives on the use of an array of AI technologies in the health care setting for design and deployment.

Environmental Factors Impacting the Development of Toxic Cyanobacterial Proliferations in a Central Texas Reservoir.

Cyanobacterial harmful algal proliferations (cyanoHAPs) are increasingly associated with dog and livestock deaths when benthic mats break free of their substrate and float to the surface. Fatalities have been linked to neurotoxicosis from anatoxins, potent alkaloids produced by certain genera of filamentous cyanobacteria. After numerous reports of dog illnesses and deaths at a popular recreation site on Lady Bird Lake, Austin, Texas in late summer 2019, water and floating mat samples were collected from several sites along the reservoir.
