Background: Airway clearance impairment has a significant impact on self-care and quality of life. Identifying clinical data, nursing diagnoses, and nursing interventions is essential to clinical reasoning and enhancing nursing care. This study aims to map the existing evidence on clinical data, nursing diagnoses, and nursing interventions addressing the nursing focus on "airway clearance"., Methods: Research was conducted based on Joanna Briggs's Scoping Review Methodology. We searched four databases for published studies until December 2023., Results: From the initial 1854 studies identified, 123 were included in the review. The findings highlighted two areas of nursing attention: one related to signs and symptom management, and the other related to education and coping strategies. The data that led to nursing diagnoses were divided into cognitive and clinical data. The nursing diagnoses were mostly related to secretion retention, excessive mucus production, and airway obstruction. The most commonly identified nursing interventions were educational interventions assembled into predesigned education programs rather than patient-tailored programs., Conclusions: Findings can add substantial value for systematizing the nursing process related to "airway clearance", improving nursing decision-making and care quality. This study was prospectively registered with the Open Science Framework (OSF) on 02 December 2022, with the registration number wx5ze.

The development of construction materials with the integration of phase change materials (PCMs) has been a topic of wide interest in the scientific community, especially in recent years, due to its positive impact on temperature regulation inside buildings. However, little is known about the behavior of materials doped with PCMs when exposed to accidental or severe environments. Currently, a large area of the planet experiences seasonal freeze-thaw effects, which impact the durability and performance of construction materials. Accordingly, the main objective of this study was to evaluate the damage caused by cyclic freeze-thaw actions on the behavior of a cement mortar, including a PEG-based form-stable PCM. An experimental methodology was developed based on the physical and mechanical characterization of mortars under normal operating conditions and after being subjected to freeze-thaw cycles. The results indicated that, under normal exposure conditions, the incorporation of aggregate functionalized with PCM led to a decrease in the mortar's water absorption capacity, compressive strength, and adhesion. However, its applicability has not been compromised. Exposure to freeze-thaw cycles caused a loss of mass in the specimens and a decrease in the compressive strength and adhesion capability of the mortar.

Organizers are specialized cell populations that orchestrate cell patterning and axon guidance in the developing nervous system. Although non-human models have led to fundamental discoveries about the organization of the nervous system midline by the floor plate, an experimental model of human floor plate would enable broader insights into regulation of human neurodevelopment and midline connectivity. Here, we have developed stem cell-derived organoids resembling human floor plate (hFpO) and assembled them with spinal cord organoids (hSpO) to generate midline assembloids (hMA). We demonstrate that hFpO promote Sonic hedgehog-dependent ventral patterning of human spinal progenitors and Netrin-dependent guidance of human commissural axons, paralleling non-human models. To investigate evolutionary-divergent midline regulators, we profiled the hFpO secretome and identified 27 evolutionarily divergent genes between human and mouse. Utilizing the hMA platform, we targeted these candidates in an arrayed CRISPR knockout screen and reveal that GALNT2 , a gene involved in O-linked glycosylation, impairs floor plate-mediated guidance of commissural axons in humans. This novel platform extends prior axon guidance discoveries into human-specific neurobiology with implications for mechanisms of nervous system evolution and neurodevelopmental disorders.

Background: The literature review notes that people in need of care from Rehabilitation Programs do not always see their continuity ensured., Objective: This study aim to analyze the perspective of Specialists Nurse in Rehabilitation Nursing in relation to the organization and specialized intervention of transitional care for older people in need of rehabilitation programs., Methods: This is a qualitative study within the interpretivist paradigm. A focus group with 8 nurses and 13 interviews with Portuguese nurses were carried out between April 2022 and February 2023. Content analysis was carried out., Results: The triangulation of the data made it possible to identify 3 categories: Coordination of a transitional care program; Empowering the person to self-manage the transitional care process and Empowering the Informal Caregiver., Conclusions: It is imperative to promote the coordination of transitional care, increase the functional capacity of the person and empower the informal caregiver., (© 2024.

Timothy syndrome (TS) is a severe, multisystem disorder characterized by autism, epilepsy, long-QT syndrome and other neuropsychiatric conditions 1 . TS type 1 (TS1) is caused by a gain-of-function variant in the alternatively spliced and developmentally enriched CACNA1C exon 8A, as opposed to its counterpart exon 8. We previously uncovered several phenotypes in neurons derived from patients with TS1, including delayed channel inactivation, prolonged depolarization-induced calcium rise, impaired interneuron migration, activity-dependent dendrite retraction and an unanticipated persistent expression of exon 8A 2-6 . We reasoned that switching CACNA1C exon utilization from 8A to 8 would represent a potential therapeutic strategy. Here we developed antisense oligonucleotides (ASOs) to effectively decrease the inclusion of exon 8A in human cells both in vitro and, following transplantation, in vivo. We discovered that the ASO-mediated switch from exon 8A to 8 robustly rescued defects in patient-derived cortical organoids and migration in forebrain assembloids. Leveraging a transplantation platform previously developed 7 , we found that a single intrathecal ASO administration rescued calcium changes and in vivo dendrite retraction of patient neurons, suggesting that suppression of CACNA1C exon 8A expression is a potential treatment for TS1. Broadly, these experiments illustrate how a multilevel, in vivo and in vitro stem cell model-based approach can identify strategies to reverse disease-relevant neural pathophysiology., (© 2024.
