Nursing students' perceptions and satisfaction with a self-learning methodology in simulated environments: A mixed-methods study.

AIM: The aim of this study was to explore the perceptions and satisfaction of last-year nursing students with the Self-Learning Methodology in Simulated Environments (MAES©). BACKGROUND: As a learning method, clinical simulation uses elements that replicate real clinical practice scenarios and facilitates the acquisition of competencies and learning objectives. Simulations promote critical thinking, knowledge, techniques and teamwork in nursing students. The Self-Learning Methodology in Simulated Environments (MAES©) is a method that integrates problem-based learning with realistic clinical simulation. DESIGN: A cross-sectional mixed-method study implemented a simulation learning method as part of the mandatory nursing training practice; that was registered in Open Science Framework (Registration DOI: https://doi.org/10.17605/OSF.IO/R89PZ). METHODS: Students were invited to complete a cross-sectional questionnaire about satisfaction with the simulation and were asked to participate in an interview about their perceptions on the simulation. All data were collected in December 2023 in a mid-sized southern Spanish university. A total of 69 last-year nursing students were enrolled in the simulation course and were selected using eligibility criteria. RESULTS: Satisfaction measures showed no significant differences across gender, university access, or age (p>0.05 each). However, strong correlations were found between students' preference for the simulation method and perceived effort value (p<0.001 each). Qualitative analysis identified key themes in different stages of simulation (prebriefing, scenario, briefing, debriefing), simulation benefits (learning, usefulness, positive emotions) and challenges (difficulty, realism, time constraints). Despite some realism concerns, overall, students viewed the methodology positively. CONCLUSIONS: The findings of this study underscore the vital role of simulation-based learning in nursing education. As the field of nursing continues to evolve, so too must the educational methods we employ, with simulation-based learning standing at the forefront of this transformative journey.

The protective effect of 1400W against ischaemia and reperfusion injury is countered by transient medullary kidney endothelial dysregulation.

Renal ischaemia and reperfusion (I/R) is caused by a sudden temporary impairment of the blood flow. I/R is a prevalent cause of acute kidney injury. As nitric oxide generated by inducible nitric oxide synthase (iNOS) has detrimental effects during I/R, the pharmacological blockade of iNOS has been proposed as a potential strategy to prevent I/R injury. The aim of this study was to improve the understanding of 1400W (an iNOS inhibitor) on renal I/R as a pharmacological strategy against kidney disease. BALB/c mice received 30 min of bilateral ischaemia, followed by 48 h or 28 days of reperfusion. Vehicle or 1400W (10 mg/kg) was administered 30 min before inducing ischaemia. We found that after 48 h of reperfusion 1400W decreased the serum creatinine, blood urea nitrogen, neutrophil gelatinase-associated lipocalin and proliferating cell nuclear antigen 3 in the I/R animals. Unexpectedly, we observed mRNA upregulation of genes involved in kidney injury, cell-cycle arrest, inflammation, mesenchymal transition and endothelial activation in the renal medulla of sham animals treated with 1400W. We also explored if 1400W promoted chronic kidney dysfunction 28 days after I/R and did not find significant alterations in renal function, fibrosis, blood pressure or mortality. The results provide evidence that 1400W may have adverse effects in the renal medulla. Importantly, our data point to 1400W-induced endothelial dysfunction, establishing therapeutic limitations for its use. KEY POINTS: Acute kidney injury is a global health problem associated with high morbidity and mortality. The pharmacological blockade of inducible nitric oxide synthase (iNOS) has been proposed as a potential strategy to prevent AKI induced by ischaemia and reperfusion (I/R). Our main finding is that 1400W, a selective and irreversible iNOS inhibitor with low toxicity that is proposed as a therapeutic strategy to prevent kidney I/R injury, produces aberrant gene expression in the medulla associated to tissue injury, cell cycle arrest, inflammation, mesenchymal transition and endothelial activation. The negative effect of 1400W observed in the renal medulla at 48 h from drug administration, is transient as it did not translate into a chronic kidney disease condition.

Alcohol use among children and adolescents with chronic pain. Scoping review.

AIM: To examine and map alcohol consumption in children and adolescents with chronic pain (CP). METHOD: A scoping review of international databases (CINAHL, WOS, PubMed, PsycINFO, Scopus, Embase, and MEDLINE) and grey literature was conducted between September 2022 and February 2023. Documents addressing the relationship between alcohol consumption and CP in children and adolescents, published in English and Spanish between 2012 and 2023, were included. Those papers with a population suffering from CP derived from neurodegenerative diseases, chronic infectious diseases or cognitive impairment were excluded. We assessed the level of evidence (LE) and the degree of recommendation (DR) of the studies included in accordance with the Scottish Intercollegiate Guidelines Network. Finally, 11 documents were considered out of the 479 reviewed. RESULTS: The relationship between substance consumption and CP in adolescents is a scarcely investigated topic. While there is a trend towards lower rates of alcohol consumption in youth with pain, there is evidence suggesting an association, particularly in cases of intense pain. The use of various substances, both legal and illegal, for pain management underscores the importance of comprehensively addressing this phenomenon in this population. CONCLUSIONS: Further research is needed to assess the relationship between alcohol consumption in children and adolescents with CP.

Low-Chloride Diet Prevents the Development of Arterial Hypertension and Protects Kidney Function in Angiotensin II-Infused Mice.

INTRODUCTION: A comprehensive pathophysiological mechanism to explain the relationship between high-salt intake and hypertension remains undefined. Evidence suggests that chloride, as the accompanying anion of sodium in dietary salt, is necessary to develop hypertension. We evaluated whether reducing dietary Cl- while keeping a standard Na+ intake modified blood pressure, cardiac hypertrophy, renal function, and vascular contractility after angiotensin II (AngII) infusion. METHODS: C56BL/6J mice fed with standard Cl- diet or a low-Cl- diet (equimolar substitution of Cl- by a mixture of Na+ salts, both diets with standard Na+ content) received AngII (infusion of 1.5 mg/kg/day) or vehicle for 14 days. We measured systolic blood pressure (SBP), glomerular filtration rate (GFR), natriuretic response to acute saline load, and contractility of aortic rings from mice infused with vehicle and AngII, in standard and low-Cl- diet. RESULTS: The mice fed the standard diet presented increased SBP and cardiac hypertrophy after AngII infusion. In contrast, low-Cl- diet prevented the increase of SBP and cardiac hypertrophy. AngII-infused mice fed a standard diet presented hampered natriuretic response to saline load, meanwhile the low-Cl- diet preserved natriuretic response in AngII-infused mice, without change in GFR. Aortic rings from mice fed with standard diet or low-Cl- diet and infused with AngII presented a similar contractile response. CONCLUSION: We conclude that the reduction in dietary Cl- as the accompanying anion of sodium in salt is protective from AngII pro-hypertensive actions due to a beneficial effect on kidney function and preserved natriuresis.

Fragment-Based Screening Identifies New Quinazolinone-Based Inositol Hexakisphosphate Kinase (IP6K) Inhibitors.

A high-throughput fragment-based screen has been employed to discover a series of quinazolinone inositol hexakisphosphate kinase (IP6K) inhibitors. IP6Ks have been studied for their role in glucose homeostasis, metabolic disease, fatty liver disease, chronic kidney disease, blood coagulation, neurological development, and psychiatric disease. IP6Ks phosphorylate inositol hexakisphosphate (IP6) to form pyrophosphate 5-diphospho-1,2,3,4,6-pentakisphosphate (IP7). Molecular docking studies and investigation of structure-activity relationships around the quinazolinone core resulted in compounds with submicromolar potency and interesting selectivity for IP6K1 versus the closely related IP6K2 and IP6K3 isoforms.

Discovery of MK-8768, a Potent and Selective mGluR2 Negative Allosteric Modulator.

Glutamate plays a key role in cognition and mood, and it has been shown that inhibiting ionotropic glutamate receptors disrupts cognition, while enhancing ionotropic receptor activity is pro-cognitive. One approach to elevating glutamatergic tone has been to antagonize presynaptic metabotropic glutamate receptor 2 (mGluR2). A desire for selectivity over the largely homologous mGluR3 motivated a strategy to achieve selectivity through the identification of mGluR2 negative allosteric modulators (NAMs). Extensive screening and optimization efforts led to the identification of a novel series of 4-arylquinoline-2-carboxamides. This series was optimized for mGluR2 NAM potency, clean off-target activity, and desirable physical properties, which resulted in the identification of improved C4 and C7 substituents. The initial lead compound from this series was Ames-positive in a single strain with metabolic activation, indicating that a reactive metabolite was likely responsible for the genetic toxicity. Metabolic profiling and Ames assessment across multiple analogs identified key structure-activity relationships associated with Ames positivity. Further optimization led to the Ames-negative mGluR2 negative allosteric modulator MK-8768.

Reduced gravity effects on gait coordinative structures.

Humans have stepped on the Lunar surface for less than 80 h of Extravehicular Activity, providing a narrow understanding of Lunar gait patterns. NASA's Human-crewed Artemis missions are quickly approaching; understanding how fractional gravity affects gait patterns will be critical for the Moon's and Mars' long-term habitation. This study examined gait patterns under 1.0 g (Earth), simulated 0.38 g (Martian), and 0.17 g (Lunar). Participants walked and ran on a treadmill supported by ARGOS (Active Response Gravity Offload System), simulating fractional gravity. Vicon motion capture data and principal component analysis software were used to capture and quantify coordinated gait structures. There were found to be significant differences (p < 0.05) in the coordinative gait structures for ambulation between fractional gravity conditions. Additionally, there were significantly higher asymmetric gait components for Lunar conditions. Finally, a skipping coordinative structure was identified within Lunar and Martian running.

Lamellar Ionenes with Highly Dissociative, Anionic Channels Provide Lower Barriers for Cation Transport.

Solid polymer electrolytes have the potential to enable safer and more energy-dense batteries; however, a deeper understanding of their ion conduction mechanisms, and how they can be optimized by molecular design, is needed to realize this goal. Here, we investigate the impact of anion dissociation energy on ion conduction in solid polymer electrolytes via a novel class of ionenes prepared using acyclic diene metathesis (ADMET) polymerization of highly dissociative, liquid crystalline fluorinated aryl sulfonimide-tagged ("FAST") anion monomers. These ionenes with various cations (Li+, Na+, K+, and Cs+) form well-ordered lamellae that are thermally stable up to 180 °C and feature domain spacings that correlate with cation size, providing channels lined with dissociative FAST anions. Electrochemical impedance spectroscopy (EIS) and differential scanning calorimetry (DSC) experiments, along with nudged elastic band (NEB) calculations, suggest that cation motion in these materials operates via an ion-hopping mechanism. The activation energy for Li+ conduction is 59 kJ/mol, which is among the lowest for systems that are proposed to operate via an ion conduction mechanism that is decoupled from polymer segmental motion. Moreover, the addition of a cation-coordinating solvent to these materials led to a >1000-fold increase in ionic conductivity without detectable disruption of the lamellar structure, suggesting selective solvation of the lamellar ion channels. This work demonstrates that molecular design can facilitate controlled formation of dissociative anionic channels that translate to significant enhancements in ion conduction in solid polymer electrolytes.

High-CO2 Levels Rather than Acidification Restrict Emiliania huxleyi Growth and Performance.

The coccolithophore Emiliania huxleyi shows a variety of responses to ocean acidification (OA) and to high-CO2 concentrations, but there is still controversy on differentiating between these two factors when using different strains and culture methods. A heavily calcified type A strain isolated from the Norwegian Sea was selected and batch cultured in order to understand whether acclimation to OA was mediated mainly by CO2 or H+, and how it impacted cell growth performance, calcification, and physiological stress management. Emiliania huxleyi responded differently to each acidification method. CO2-enriched aeration (1200 µatm, pH 7.62) induced a negative effect on the cells when compared to acidification caused by decreasing pH alone (pH 7.60). The growth rates of the coccolithophore were more negatively affected by high pCO2 than by low pH without CO2 enrichment with respect to the control (400 µatm, pH 8.1). High CO2 also affected cell viability and promoted the accumulation of reactive oxygen species (ROS), which was not observed under low pH. This suggests a possible metabolic imbalance induced by high CO2 alone. In contrast, the affinity for carbon uptake was negatively affected by both low pH and high CO2. Photochemistry was only marginally affected by either acidification method when analysed by PAM fluorometry. The POC and PIC cellular quotas and the PIC:POC ratio shifted along the different phases of the cultures; consequently, calcification did not follow the same pattern observed in cell stress and growth performance. Specifically, acidification by HCl addition caused a higher proportion of severely deformed coccoliths, than CO2 enrichment. These results highlight the capacity of CO2 rather than acidification itself to generate metabolic stress, not reducing calcification.

Fundamental Science and Engineering Questions in Planetary Cave Exploration.

Nearly half a century ago, two papers postulated the likelihood of lunar lava tube caves using mathematical models. Today, armed with an array of orbiting and fly-by satellites and survey instrumentation, we have now acquired cave data across our solar system-including the identification of potential cave entrances on the Moon, Mars, and at least nine other planetary bodies. These discoveries gave rise to the study of planetary caves. To help advance this field, we leveraged the expertise of an interdisciplinary group to identify a strategy to explore caves beyond Earth. Focusing primarily on astrobiology, the cave environment, geology, robotics, instrumentation, and human exploration, our goal was to produce a framework to guide this subdiscipline through at least the next decade. To do this, we first assembled a list of 198 science and engineering questions. Then, through a series of social surveys, 114 scientists and engineers winnowed down the list to the top 53 highest priority questions. This exercise resulted in identifying emerging and crucial research areas that require robust development to ultimately support a robotic mission to a planetary cave-principally the Moon and/or Mars. With the necessary financial investment and institutional support, the research and technological development required to achieve these necessary advancements over the next decade are attainable. Subsequently, we will be positioned to robotically examine lunar caves and search for evidence of life within Martian caves; in turn, this will set the stage for human exploration and potential habitation of both the lunar and Martian subsurface.

Discovery and Evaluation of Novel Angular Fused Pyridoquinazolinonecarboxamides as RNA Polymerase I Inhibitors.

RNA polymerase I (Pol I) transcribes ribosomal DNA (rDNA) into the 47S ribosomal RNA (rRNA) precursor. Further processing produces the 28S, 5.8S, and 18S rRNAs that are assembled into mature ribosomes. Many cancers exhibit higher Pol I transcriptional activity, reflecting a need for increased ribosome biogenesis and protein synthesis and making the inhibition of this process an attractive therapeutic strategy. Lead molecule BMH-21 (1) has been established as a Pol I inhibitor by affecting the destruction of RPA194, the Pol I large catalytic subunit. A previous structure-activity relationship (SAR) study uncovered key pharmacophores, but activity was constrained within a tight chemical space. This work details further SAR efforts that have yielded new scaffolds and improved off-target activity while retaining the desired RPA194 degradation potency. Pharmacokinetic profiling was obtained and provides a starting point for further optimization. New compounds present additional opportunities for the development of Pol I inhibitory cancer therapies.

An Animation- Versus Text-Based Computer-Tailored Game Intervention to Prevent Alcohol Consumption and Binge Drinking in Adolescents: Study Protocol.

The purpose of this paper is to describe the protocol for the design, implementation, and evaluation of an animation- versus text-based computer tailoring game intervention aimed at preventing alcohol consumption and binge drinking (BD) in adolescents. A cluster-randomized controlled trial (CRCT) is carried out in students aged 14-19 enrolled in 24 high schools from Andalusia (Spain), which are randomized either to experimental (EC-1, EC-2) or waiting-list control conditions (CC). EC-1 receives an online intervention (Alerta Alcohol) with personalized health advice, using textual feedback and several gamification techniques. EC-2 receives an improved version (Alerta Alcohol 2.0) using animated videos and new gamification strategies. Both programs consist of nine sessions (seven taking place at high school and two at home): session 1 or baseline, sessions 2 and 3 that provide tailored advice based on the I-Change Model; sessions 4, 5, 7, and 8 are booster sessions, and sessions 6 and 9 are follow-up questionnaires at six and twelve months. The CC completes the baseline and the evaluation questionnaires. The primary outcome is BD within 30 days before post-test evaluations, and as secondary outcomes we assess other patterns of alcohol use. The findings should help the development of future alcohol drinking prevention interventions in adolescents.

Occurrence of recently diagnosed atrial fibrillation in the immediate postoperative period of myocardial revascularization surgery. Although common, a devalued complication.

Atrial fibrillation (AF) is the most common arrhythmia in the postoperative period of cardiac surgery, with a prevalence between 15-40% after coronary artery bypass surgery (CABG). Several strategies have been tested for the prevention and management of AF postoperatively. Previous studies and analysis of records have shown higher rates of hospitalization and clinical outcomes associated with this entity, including increased mortality in the short- and long-term. This perspective reviews the topic, and offers recommendations for the management of this arrhythmia in the postoperative period of CABG, with a special focus on anticoagulation strategies.

Assessment of patients with acute respiratory symptoms during the COVID-19 pandemic by Telemedicine: clinical features and impact on referral.

OBJECTIVE: To characterize variables associated with referral to the emergency department following Telemedicine consultation during the COVID-19 pandemic. METHODS: Cross-sectional retrospective study conducted between March and May 2020, with a sample of 500 adult patients. The inclusion criterion was the manifestation of respiratory symptoms, regardless of type. RESULTS: The mean age of patients was 34.7±10.5 years, and 59% were women. Most patients (62.6%) perceived their own health status as malaise and some (41.4%) self-diagnosed COVID-19. Cough (74.4%), rhinorrhea (65.6%), sore throat (38.6%) and sneezing (20.6%) were the most common infection-related symptoms. Overall, 29.4% and 16% of patients reported dyspnea and chest pain, respectively. The Roth score was calculated for a sizeable number of patients (67.6%) and was normal, moderately altered or severely altered in 83.5%, 10.7% and 5.6% of patients, respectively. The percentage of suspected COVID-19 cases was 67.6%. Of these, 75% were managed remotely and only one quarter referred for emergency assessment. CONCLUSION: Telemedicine assessment is associated with reclassification of patient's subjective impression, better inspection of coronavirus disease 2019 and identification of risk patients. Referral is therefore optimized to avoid inappropriate in-person assessment, and low-risk patients can be properly guided. Telemedicine should be implemented in the health care system as a cost-effective strategy for initial assessment of acute patients.

Early life trophodynamic influence on daily growth patterns of the Alboran Sea sardine (Sardina pilchardus) from two distinct nursery habitats (bays of málaga and almería) in the western Mediterranean Sea.

The Alborán Sea sardine (Sardina pilchardus) is the most abundant small pelagic fish in the Mediterranean Sea. Along the northern coast of the Alborán Sea, Málaga and Almería Bay are two important nursery grounds with contrasting oceanographic characteristics. Post-larval stages of S. pilchardus were collected during the late autumn and late winter along with the mesozooplankton community. We examined the influence of feeding behavior on larval growth using environmental variables, daily growth metrics, otolith biometry, stable isotope analysis and trophodynamics. Trophic positions were calculated using mesoozooplankton as potential prey for S. pilchardus. During both seasons, we observed faster growth in larger otoliths that also corresponded to higher trophic positions. Our results indicate that the isotopic signature of larvae is highly influenced by the mesozooplankton community structure. Moreover, the trophic variables showed a significant linear relationship with the estimated ages for all larvae indicating dietary changes throughout ontogenic development.

RESUMO Objetivo: Caracterizar as variáveis associadas ao encaminhamento à emergência após consulta de Telemedicina durante a pandemia de COVID-19. Métodos: Estudo transversal e retrospectivo, realizado entre março e maio de 2020, com amostra de 500 pacientes adultos. O critério de inclusão foi apresentação de sintomas respiratórios, independente do tipo. Resultados: A média de idade dos pacientes foi de 34,7±10,5 anos, e 59% eram do sexo feminino. A maioria dos pacientes (62,6%) se classificou subjetivamente como tendo um mal-estar, e alguns (41,4%) autodiagnosticaram COVID-19. Tosse (74,4%), rinorreia (65,6%), dor de garganta (38,6%) e espirros (20,6%) foram os sintomas mais comuns relacionados à infecção. Dispneia e dor torácica foram relatados por 29,4% e 16% dos pacientes, respectivamente. Foi calculado o escore de Roth de um número considerável de pacientes (67,6%), obtendo resultado normal em 83,5%, moderadamente alterado em 10,7% e grave em 5,6%. A percentagem de casos suspeitos de COVID-19 foi de 67,6%, e 75% desses foram gerenciados remotamente, com apenas um quarto sendo encaminhado para avaliação imediata na emergência. Conclusão: A avaliação da Telemedicina está associada à reclassificação da impressão subjetiva do paciente, melhor inspeção da COVI-19 e identificação de pacientes de risco. O encaminhamento é otimizado, para evitar avaliação presencial inadequada, e permite que os pacientes de baixo risco sejam orientados de forma apropriada. A Telemedicina deve ser implementada no sistema de saúde como estratégia com boa relação custo-efetividade para a avaliação inicial de pacientes agudos.
