Methods: The study universe included 129 bibliometric articles on nursing retrieved from Scopus.
We compared the clinical and analytical performance of Alzheimer's disease (AD) plasma biomarkers measured using the single-molecule array (Simoa) and Lumipulse platforms. We quantified the plasma levels of amyloid beta 42 (Aβ42), Aβ40, phosphorylated tau (Ptau181), and total tau biomarkers in 81 patients with mild cognitive impairment (MCI), 30 with AD, and 16 with non-AD dementia. We found a strong correlation between the Simoa and Lumipulse methods.

Background: Despite the evidence supporting the association between HWEs and job satisfaction, nursing retention, and patient outcomes, nurses still have high rates of burnout, mental health problems and intent to leave. To address this challenge, a blended training was created and piloted with the aim to highlight the relevance and impact of HWEs, enhancing its transferability to daily practice.
Gastrulation is a fundamental and critical process of animal development whereby the mass of cells that results from the proliferation of the zygote transforms itself into a recognizable outline of an organism. The last few years have seen the emergence of a number of experimental models of early mammalian embryogenesis based on Embryonic Stem (ES) cells. One of this is the Gastruloid model.

Methods: A descriptive instrumental study was conducted involving construct definition, development of the tool, analysis of the content validity, and psychometric evaluation. Consensus regarding the content was obtained through a two-round Delphi process, and the resulting tool (the NURSPeM) was administered to nursing students to examine its internal consistency, temporal stability, and construct validity, the latter through exploratory factor analysis.
A striking property of vertebrate embryos is the emergence of a conserved body plan across a wide range of organisms through the process of gastrulation. As the body plan unfolds, gene regulatory networks (GRNs) and multicellular interactions (cell regulatory networks, CRNs) combine to generate a conserved set of morphogenetic events that lead to the phylotypic stage. Interrogation of these multilevel interactions requires manipulation of the mechanical environment, which is difficult in vivo.

Previous approaches to derive embryoids either lack the physiological morphology and signaling interactions, or are unconducive to model post-gastrulation development. Here, we report a bioengineering-inspired approach aimed at addressing this gap.

Several pharmaceutical companies use animal-free in vitro models which allow a more rapid selection of lead compounds and contribute to 3Rs principles ('replace, reduce and refine') by streamlining the selection of promising compounds submitted to further regulatory studies in animals. Currently available in vitro models typically rely on adherent monolayer cultures or disorganized 3D structures, both of which lack the spatiotemporal and morphological context of the developing embryo.

Purpose: To understand the lived experience of nursing students who joined the health care workforce during the first wave of the COVID-19 outbreak (March-May 2020).
Method: Qualitative content analysis of the reflective journals of 40 nursing students in Spain.
Background: To conduct a pilot study on an alternative model for the provision of respiratory therapies in sleep apnea-hypopnea syndrome (SAHS) by internalizing the service with the purchase, monitoring and control of continuous positive airway pressure (CPAP) equipment by the hospital.
Methods: An observational, prospective pilot study of comparative cost analysis by internalizing the service to include all patients up to a budget limit of 5000 euros. The cost of internalizing the service included the acquisition of CPAP equipment and all the necessary accessories in addition to the nursing days necessary to track the patients.
Background: Recent epidemics have placed overwhelming demands on health systems, leading at times to the deployment of nursing students during the crisis. Little is known about the impact this experience has on students. Although studies have explored nursing students' knowledge about infection control, there are no specific recommendations regarding how these issues should be addressed in nurse education.

Our objective was to investigate the association between sleep and several biomarkers that reflect distinct aspects of AD physiopathology.
Methods: The cohort included 104 individuals with mild-moderate AD.
A fundamental question in developmental biology is how the early embryo establishes the spatial coordinate system that is later important for the organization of the embryonic body plan. Although we know a lot about the signaling and gene-regulatory networks required for this process, much less is understood about how these can operate to pattern tissues in the context of the extensive cell movements that drive gastrulation. In zebrafish, germ layer specification depends on the inheritance of maternal mRNAs [1-3], cortical rotation to generate a dorsal pole of β-catenin activity [4-8], and the release of Nodal signals from the yolk syncytial layer (YSL) [9-12].

Methods: One hundred and thirteen patients were consecutively recruited from April 2012 to April 2014. Measurement of CSF biomarkers (amyloid-β42 (Aβ42), total tau (t-tau) and phosphorylated tau (p-tau)) and a neuropsychological evaluation were performed for all patients.
Objective: The aim of this study was to translate into Spanish the Self Competence in Death Work Scale (SC-DWS) and to explore its psychometric properties of validity and reliability.
Method: Participants were 106 nursing professionals, who worked in units related to care at the end of life. Participants answered a questionnaire containing the Spanish forms of the Self-Competence in Death Work Scale (SC-DWS), Perceived Life Significance Scale (PLSS), Death Anxiety Inventory-Revised (DAI-R), Hospital Anxiety and Depression Scale (HADS) and General Self Efficacy Scale (GSE).
The emergence of multiple axes is an essential element in the establishment of the mammalian body plan. This process takes place shortly after implantation of the embryo within the uterus and relies on the activity of gene regulatory networks that coordinate transcription in space and time. Whereas genetic approaches have revealed important aspects of these processes, a mechanistic understanding is hampered by the poor experimental accessibility of early post-implantation stages.

While a plethora of expression data exists for ligands, receptors and pathway regulators, we know little about the spatial organization or dynamics of signaling in individual cells within populations. To this end we developed a transcriptional readout of FGF/ERK activity by targeting a histone H2B-linked Venus fluorophore to the endogenous locus of Spry4, an early pathway target, and generated Spry4 embryonic stem cells (ESCs) and a derivative mouse line.

Objective: To determine the prevalence and characteristics of MHs in Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI) patients, and to describe their potential relationship with cognition, behavioral symptoms, and use of psychoactive drugs.

The establishment of the anteroposterior (AP) axis is a crucial step during animal embryo development. In mammals, genetic studies have shown that this process relies on signals spatiotemporally deployed in the extra-embryonic tissues that locate the position of the head and the onset of gastrulation, marked by T/Brachyury () at the posterior of the embryo. Here, we use gastruloids, mESC-based organoids, as a model system with which to study this process.

By bridging scales, single-cell approaches should, in principle, galvanize our understanding of how individual cells adopt distinct fates as they build complex tissues.
