RESUMO

The microbial compositions from concurrent peri-implant and periodontal lesions were compared, since the results reported in the literature on the etiological relationship between these oral pathologies are contradictory. Microbial compositions from nine patients were evaluated using Illumina MiSeq sequencing of 16S rRNA gene amplicons and Principal Components Analysis. Comparisons between the use of curettes or paper points as collection methods and between bacterial composition in both pathologies were performed. Paper points allowed the recovery of a higher number of bacterial genera. A higher bacterial diversity was found in peri-implantitis compared to periodontal samples from the same patient, while a greater number of operational taxonomic units (OTUs) were present in the corresponding periodontal samples. A higher abundance of oral pathogens, such as Porphyromonas or Treponema, was found in peri-implantitis sites. The opposite trend was observed for Aggregatibacter abundance, which was higher in periodontal than in peri-implantitis lesions, suggesting that both oral pathologies could be considered different but related diseases. Although the analysis of a higher number of samples would be needed, the differences regarding the microbial composition provide a basis for further understating the pathogenesis of peri-implant infections.

RESUMO

Background: In cervical cancer (CC), miR-218-5p, -124-3p, and -23b-3p act as tumor suppressors. These miRNAs have specific and common target genes that modulate apoptosis, proliferation, invasion, and migration; biological processes involved in cancer. Methods: miR-218-5p, -124-3p, and -23b-3p mimics were transfected into C-33A and CaSki cells, and RT-qPCR was used to quantify the level of each miRNA and NACC1. Proliferation was assessed by BrdU and apoptosis by Annexin V/PI. In the TCGA and The Human Protein Atlas databases, the level of NACC1 mRNA and protein (putative target of the three miRNAs) was analyzed in CC and normal tissue. The relationship of NACC1 with the overall survival in CC was analyzed in GEPIA2. NACC1 mRNA and protein levels were higher in CC tissues compared with cervical tissue without injury. Results: An increased expression of NACC1 was associated with lower overall survival in CC patients. The levels of miR-218-5p, -124-3p, and -23b-3p were lower, and NACC1 was higher in C-33A and CaSki cells compared to HaCaT cells. The increase of miR-218-5p, -124-3p, and -23b-3p induced a significant decrease in NACC1 mRNA. The transfection of the three miRNAs together caused more drastic changes in the level of NACC1, in the proliferation, and in the apoptosis with respect to the individual transfections of each miRNA. Conclusion: The results indicate that miR-218-5p, -124-3p, and -23b-3p act synergistically to decrease NACC1 expression and proliferation while promoting apoptosis in C-33A and CaSki cells. The levels of NACC1, miR-218-5p, -124-3p, and -23b-3p may be a potential prognostic indicator in CC.

RESUMO

BRAFV600E is the most prevalent mutation in thyroid cancer and correlates with poor prognosis and therapy resistance. Although selective inhibitors of BRAFV600E have been developed, more advanced tumors such as anaplastic thyroid carcinomas show a poor response in clinical trials. Therefore, the study of alternative survival mechanisms is needed. Since metabolic changes have been related to malignant progression, in this work we explore metabolic dependencies of thyroid tumor cells to exploit them therapeutically. Our results show that respiration of thyroid carcinoma cells is highly dependent on fatty acid oxidation and, in turn, fatty acid mitochondrial availability is regulated through macroautophagy/autophagy. Furthermore, we show that both lysosomal inhibition and the knockout of the essential autophagy gene, ATG7, lead to enhanced lipolysis; although this effect is not essential for survival of thyroid carcinoma cells. We also demonstrate that following inhibition of either autophagy or fatty acid oxidation, thyroid tumor cells compensate oxidative phosphorylation deficiency with an increase in glycolysis. In contrast to lipolysis induction, upon autophagy inhibition, glycolytic boost in autophagy-deficient cells is essential for survival and, importantly, correlates with a higher sensitivity to the BRAFV600E selective inhibitor, vemurafenib. In agreement, downregulation of the glycolytic pathway results in enhanced mitochondrial respiration and vemurafenib resistance. Our work provides new insights into the role of autophagy in thyroid cancer metabolism and supports mitochondrial targeting in combination with vemurafenib to eliminate BRAFV600E-positive thyroid carcinoma cells.Abbreviations: AMP: adenosine monophosphate; ATC: anaplastic thyroid carcinoma; ATG: autophagy related; ATP: adenosine triphosphate; BRAF: B-Raf proto-oncogene, serine/threonine kinase; Cas9: CRISPR-associated protein; CREB: cAMP responsive element binding protein; CRISPR: clustered regularly interspaced short palindromic repeats; 2DG: 2-deoxyglucose; FA: fatty acid; FAO: fatty acid oxidation; FASN: fatty acid synthase; FCCP: trifluoromethoxy carbonyl cyanide phenylhydrazone; LAMP1: lysosomal associated membrane protein 1; LIPE/HSL: lipase E, hormone sensitive type; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; OCR: oxygen consumption rate; OXPHOS: oxidative phosphorylation; PRKA/PKA: protein kinase cAMP-activated; PTC: papillary thyroid carcinoma; SREBF1/SREBP1: sterol regulatory element binding transcription factor 1.

RESUMO

BACKGROUND: The reimbursement of erenumab in Spain and other European countries is currently restricted because of the cost of this novel therapy to patients with migraine who have experienced previous failures to traditional preventive treatments. However, this reimbursement policy should be preferably based on cost-effectiveness studies, among other criteria. This study performed a cost-effectiveness analysis of erenumab versus topiramate for the prophylactic treatment of episodic migraine (EM) and versus placebo for chronic migraine (CM). METHODS: A Markov model with a 10-year time horizon, from the perspective of the Spanish National Healthcare System, was constructed based on data from responder and non-responder patients. A responder was defined as having a minimum 50% reduction in the number of monthly migraine days (MMD). A hypothetical cohort of patients with EM with one or more prior preventive treatment failures and patients with CM with more than two treatment failures was considered. The effectiveness score was measured as an incremental cost per quality-adjusted life year (QALY) gained and cost per migraine day (MD) avoided. Data from clinical outcomes and patient characteristics were obtained from erenumab clinical trials (NCT02066415, STRIVE, ARISE, LIBERTY and HER-MES). Deterministic and probabilistic sensitivity analyses were performed to validate the robustness of the model. RESULTS: After a 10-year follow-up, the estimated QALYs were 5.88 and 6.11 for patients with EM treated with topiramate and erenumab, respectively. Erenumab showed an incremental cost per patient of €4,420 vs topiramate. For CM patients, erenumab resulted in 0.756 QALYs gained vs placebo; and an incremental cost of €1,814. Patients treated with erenumab achieved reductions in MD for both EM and CM (172 and 568 MDs, respectively). The incremental cost per QALY gained with erenumab was below the Spanish threshold of €30,000/QALY for both health and societal perspectives (EM €19,122/QALY and CM €2,398/QALY). CONCLUSIONS: Erenumab is cost-effective versus topiramate as a preventive treatment for EM and versus placebo for patients with CM from the perspective of the Spanish National Health System.

RESUMO

In Spain, the advances in medicine and pharmacology, technology, etc., together with the low birth rates (a product of various social phenomena that occurred during the 20th century), cause an unprecedented population aging, a situation that extends to the rest of the countries. Europeans. This circumstance leads to an increase in the number of elderly people in a situation of dependency, entailing challenges such as the increase in chronic diseases and palliative stages, the management of informal care, the economic cost of formal care and unwanted loneliness (SND). , among other. Regarding this last challenge, and its consequences, it can be said that: it is a silent problem of a new order that affects more and more people in Spain, Europe and the world; It represents a source of suffering for those who suffer from it and a limitation of the right to participate in society; causes negative consequences for health and emotional well-being; It is associated with certain social and economic costs. Today it is estimated that in our country 13.4% of people suffer from SND, that those who suffer from it have been in this situation for approximately six years and that 22.9% experience this feeling of loneliness throughout the day. Likewise, in Europe as a whole, around thirty million people frequently feel lonely. Considering the sex variable, it is women who suffer from this problem with the highest prevalence (14.8% in the case of women and 12.1% in the case of men). Among the factors associated with this trend is life expectancy at birth. It should be said in this regard that, in recent decades, our country has experienced an increase in life expectancy by almost five years, being greater in the case of women. By 2022 this increase amounts to 83.08 years (women=85.7/men=80.3), a fact that places Spain in tenth place in the classification of the 194 countries that publish their life expectancy.


En España los avances de la medicina y la farmacología, la tecnología, etc., unidos a los bajos índices de natalidad (producto de diversos fenómenos sociales acaecidos durante el siglo XX), originan un envejecimiento poblacional sin precedentes, situación extendida al resto de países europeos. Tal circunstancia lleva aparejada un incremento de personas mayores en situación de dependencia, conllevando desafíos como pueden ser el aumento de las enfermedades crónicas y los estadios paliativos, la gestión del cuidado informal, el coste económico del cuidado formal y la soledad no deseada (SND), entre otras. Respecto de este último desafío, y sus consecuencias, se puede decir que: se trata de un problema silente de nuevo orden que afecta cada vez a más personas en España, Europa y el mundo; supone una fuente de sufrimiento para quien la padece y una limitación del derecho de participación en la sociedad; provoca consecuencias negativas para la salud y el bienestar emocional; lleva asociada ciertos costes sociales y económicos. Hoy día se estima que en nuestro país un 13,4% de las personas sufren SND, que quienes la padecen llevan aproximadamente seis años en dicha situación y que el 22,9% experimenta este sentimiento de soledad durante todo el día.

RESUMO

Introduction: Atherosclerotic cardiovascular disease (ASCVD) is one of the main causes of morbidity and mortality in developed countries and entails high resources use and costs for health systems. The risk of suffering future cardiovascular (CV) events and the consequent resources use is higher in those patients who have already had a previous cardiovascular event. The objective of the study was to determine the average annual cost of patients with a new or recurrent atherosclerotic CV event during the 2 years after the event. Methodology: Retrospective observational study of electronic medical records of patients from the BIG-PAC® database (7 integrated health areas of 7 Autonomous Communities; n = 1.8 million). Patients with a new or recurrent episode of ASCVD (angina, acute myocardial infarction, transient ischemic attack, stroke, or peripheral arterial disease) between 1-Jan-2017 and 31-Dec-2018 were included. The resources use within two years of the diagnosis was estimated in order to estimate the average cost of patient follow-up. Results: A total of 26,976 patients with an ASCVD episode were identified during the recruitment period; Out of them, 6,798 had a recurrent event during the follow-up period and 2,414 died. The average costs per patient were €11,171 during the first year and €9,944 during the second year. Discussion: Patients with ASCVD represent a significant economic burden for the health system and for society. Despite the perception that drug costs in the follow-up of chronic patients imply a high percentage of the costs, these accounted for only one tenth of the total amount. Implementing preventive programs and increasing the control of cardiovascular risk factors may have a significant social and health impact by helping to reduce mortality and costs for the Spanish National Health System. The costs derived from pharmacological treatments were obtained from the NHS pricing nomenclator database (https://www.sanidad.gob.es/profesionales/nomenclator.do).

RESUMO

Sudden cardiac death due to ventricular fibrillation (VF) during ST-elevation acute myocardial infarction (STEAMI) significantly contributes to cardiovascular-related deaths. Although VF has been linked to genetic factors, variations in copy number variation (CNV), a significant source of genetic variation, have remained largely unexplored in this context. To address this knowledge gap, this study performed whole exome sequencing analysis on a cohort of 39 patients with STEAMI who experienced VF, aiming to elucidate the role of CNVs in this pathology. The analysis revealed CNVs in the form of duplications in the PARP2 and TTC5 genes as well as CNVs in the form of deletions in the MUC15 and PPP6R1 genes, which could potentially serve as risk indicators for VF during STEAMI. The analysis also underscores notable CNVs with an average gene copy number equal to or greater than four in DEFB134, FCGR2C, GREM1, PARM1, SCG5, and UNC79 genes. These findings provide further insight into the role of CNVs in VF in the context of STEAMI.

RESUMO

cAMP has been reported to be an essential driver of sperm capacitation. In bovine sperm cAMP efflux through multidrug resistance-associated protein 4 (MRP4) has been suggested to maintain intracellular cAMP homeostasis and generate extracellular signaling able to regulate capacitation. The aim of this work was to determine whether extracellular cAMP may influence in vitro pig sperm capacitation and acquisition of fertilizing ability and to evaluate the role of MRP4. In vitro sperm capacitation and gamete coincubation were performed in Brackett and Oliphant's medium (BO) in presence of caffeine (Ctr+) or in BO without caffeine (Ctr-) supplemented with 0, 8, 9, 10 mM cAMP. Despite the percentage of capacitated sperm, assayed by immunolocalization of tyrosine-phosphorylated proteins, was significantly lower in Ctr- compared to Ctr+, it increased supplementing 10 mM cAMP to Ctr- reaching values similar to Ctr+. The absence of caffeine during gamete coincubation reduced the fertilization rate compared to Ctr+, while 10 mM cAMP supplementation to Ctr- increased the fertilization rate reaching values similar to Ctr + . The presence of MRP4 in pig spermatozoa was detected for the first time by western blot and immunohistochemistry assays. To evaluate MRP4 role on pig sperm capacitation, in vitro capacitation and gamete coincubation were performed in Ctr + in presence of MK571, a MRP4 selective inhibitor. MK571 reduced the percentage of capacitated cells and the fertilization rate, while cAMP addition fully reversed MRP4 blockade consequences. Present findings suggest that, under our in vitro conditions, extracellular cAMP and MRP4 activity influence pig sperm capacitating events.

RESUMO

The Mitochondrial distribution pattern or MDP in mammalian oocytes serves as an indicator of their cytoplasmic maturity, with a heterogeneous pattern associated with mature cytoplasm. Currently, MDP assessment involves fluorescent labelling of mitochondria followed by visual evaluation, as no quantitative method exists. Our objective was to develop a quantitative approach to assess MDP in mature equine oocytes. Equine oocytes, obtained by ovum pick up (OPU) were matured in vitro, and only metaphase II oocytes were used in the study (n = 56). Following denudation, oocytes were fixed, stained with MitoTracker™ Red CMXRos (50 nM in TCM-199 with Hank´s salts and 10% FBS) for 15 min at 38 °C, and then incubated with 2.5 µg/ml Hoechst 33342 for 10 min at 38 °C. Confocal microscope images were acquired, and the oocyte's MDP was visually classified as either homogeneous (HoD; n = 17) or heterogeneous (HeD; n = 39). For quantitative analysis, Fiji-ImageJ software was employed. Background subtraction was performed, and a 1-pixel line along the diameter was drawn to calculate the intensity profile. Fluorescence intensities were normalized, and ratios of peripheral to central fluorescence intensity were determined. Student´s t-test was used for comparations; MDP ratio was (mean ± standard error of the mean): 0.8 ± 0.02 for HoD and 0.3 ± 0.02 for HeD (p < 0.001). These results demonstrate concordance between quantitative and qualitative MDP assessment in mature equine oocytes. Our study describes a new approach to quantify mitochondrial distribution pattern and cytoplasmic maturation in mature equine oocytes.

RESUMO

In this research work, a series of 16 quinazoline derivatives bearing ibuprofen and an amino acid were designed as inhibitors of epidermal growth factor receptor tyrosine kinase domain (EGFR-TKD) and cyclooxygenase-2 (COX-2) with the intention of presenting dual action in their biological behavior. The designed compounds were synthesized and assessed for cytotoxicity on epithelial cancer cells lines (AGS, A-431, MCF-7, MDA-MB-231) and epithelial non-tumorigenic cell line (HaCaT). From this evaluation, derivative 6 was observed to exhibit higher cytotoxic potency (IC50 ) than gefitinib (reference drug) on three cancer cell lines (0.034 µM in A-431, 2.67 µM in MCF-7, and 3.64 µM in AGS) without showing activity on the non-tumorigenic cell line (>100 µM). Furthermore, assessment of EGFR-TKD inhibition by 6 showed a discreet difference compared to gefitinib. Additionally, 6 was used to conduct an in vivo anti-inflammatory assay using the 12-O-tetradecanoylphorbol-3-acetate (TPA) method, and it was shown to be 5 times more potent than ibuprofen. Molecular dynamics studies of EGFR-TKD revealed interactions between compound 6 and M793. On the other hand, one significant interaction was observed for COX-2, involving S531. The RMSD graph indicated that the ligand remained stable in 50 ns.

RESUMO

The tumor immune microenvironment of thyroid cancer is the heterogeneous histological space in which tumor cells coexist with host cells. Published data from this review were identified by search and selection database of Pubmed, Elsevier, and Science Direct. Searching was made in two steps using different keywords. In thyroid pathology, the inflammatory response is very important, and might have a key role finding new diagnostic and therapeutic methods, particularly in thyroid cancer. Different immune cells may be more or less present in different types of thyroid cancer and may even have different functions, hence the importance of knowing their presence in different thyroid tumor pathologies. Cancer-related inflammation could be a useful target for new diagnostic and therapeutic strategies by analyzing peritumoral and intratumoral immune cells in different types of thyroid tumors. Moreover, novel strategies for thyroid cancer treatments, such as monoclonal antibodies targeting checkpoint inhibitors, are emerging as promising alternatives.

RESUMO

INTRODUCTION: The implementation of Information and Communication Technology (ICT) in daily healthcare practice has become standardized. In relation to education within the nursing degree, ICTs make it possible to carry out practical immersion training from the" classroom or from any other place with an Internet connection, as evidenced by circumstances that have occurred in recent years, such as the pandemic caused by COVID-19. OBJECTIVE: Design and assess a didactic simulation program for the training of the nursing process that promotes learning in the nursing care METHODOLOGY: The methodological approach is quantitative and it is a descriptive cross-sectional study. The sampling method used was non-probabilistic by convenience. RESULTS: When observing the comparison of the averages of student satisfaction with respect to the didactic simulator, it is worth mentioning that all the items are above 2.80 on a score in which "0" is the minimum value and "5" the maximum value. The results of the use of the computer tool by the students, we highlight as significant data that all the items present an average equal to or lower than 3.04 out of 7, where "1" corresponds to a lot of use and "7" to little use. CONCLUSION: The implication of ICT in the teaching-learning process among Nursing Degree students, it is considered optimal. when analyzing the answers obtained in the items that refer to a higher ease in the execution of development of Care plans, a fundamental work in Nursing performance.

RESUMO

Many bioinformatics tools are available for the quantitative analysis of proteomics experiments. Most of these tools use a dedicated statistical model to derive absolute quantitative protein values from mass spectrometry (MS) data. Here, we present iSanXoT, a standalone application that processes relative abundances between MS signals and then integrates them sequentially to upper levels using the previously published Generic Integration Algorithm (GIA). iSanXoT offers unique capabilities that complement conventional quantitative software applications, including statistical weighting and independent modeling of error distributions in each integration, aggregation of technical or biological replicates, quantification of posttranslational modifications, and analysis of coordinated protein behavior. iSanXoT is a standalone, user-friendly application that accepts output from popular proteomics pipelines and enables unrestricted creation of quantification workflows and fully customizable reports that can be reused across projects or shared among users. Numerous publications attest the successful application of diverse integrative workflows constructed using the GIA for the analysis of high-throughput quantitative proteomics experiments. iSanXoT has been tested with the main operating systems. Download links for the corresponding distributions are available at https://github.com/CNIC-Proteomics/iSanXoT/releases.

RESUMO

While reperfusion, or restoration of coronary blood flow in acute myocardial infarction, is a requisite for myocardial salvage, it can paradoxically induce a specific damage known as ischemia/reperfusion (I/R) injury. Our understanding of the precise pathophysiological molecular alterations leading to I/R remains limited. In this study, we conducted a comprehensive and unbiased time-course analysis of post-translational modifications (PTMs) in the post-reperfused myocardium of two different animal models (pig and mouse) and evaluated the effect of two different cardioprotective therapies (ischemic preconditioning and neutrophil depletion). In pigs, a first wave of irreversible oxidative damage was observed at the earliest reperfusion time (20 min), impacting proteins essential for cardiac contraction. A second wave, characterized by irreversible oxidation on different residues and reversible Cys oxidation, occurred at late stages (6-12 h), affecting mitochondrial, sarcomere, and inflammation-related proteins. Ischemic preconditioning mitigated the I/R damage caused by the late oxidative wave. In the mouse model, the two-phase pattern of oxidative damage was replicated, and neutrophil depletion mitigated the late wave of I/R-related damage by preventing both Cys reversible oxidation and irreversible oxidation. Altogether, these data identify protein PTMs occurring late after reperfusion as an actionable therapeutic target to reduce the impact of I/R injury.

RESUMO

BACKGROUND: Current polymer-based drug-eluting stents (DESs) have fundamental issues about inflammation and delayed re-endothelializaton of the vessel wall. Substance-P (SP), which plays an important role in inflammation and endothelial cells, has not yet been applied to coronary stents. Therefore, this study compares poly lactic-co-glycolic acid (PLGA)-based everolimus-eluting stents (PLGA-EESs) versus 2-methacryloyloxyethyl phosphorylcholine (MPC)-based SP-eluting stents (MPC-SPs) in in-vitro and in-vivo models. METHODS: The morphology of the stent surface and peptide/drug release kinetics from stents were evaluated. The in-vitro proliferative effect of SP released from MPC-SP is evaluated using human umbilical vein endothelial cell. Finally, the safety and efficacy of the stent are evaluated after inserting it into a pig's coronary artery. RESULTS: Similar to PLGA-EES, MPC-SP had a uniform surface morphology with very thin coating layer thickness (2.074 µm). MPC-SP showed sustained drug release of SP for over 2 weeks. Endothelial cell proliferation was significantly increased in groups treated with SP (n = 3) compared with the control (n = 3) and those with everolimus (n = 3) (SP: 118.9 ± 7.61% vs. everolimus: 64.3 ± 12.37% vs. the control: 100 ± 6.64%, p < 0.05). In the animal study, the percent stenosis was higher in MPC-SP group (n = 7) compared to PLGA-EES group (n = 7) (MPC-SP: 28.6 ± 10.7% vs. PLGA-EES: 16.7 ± 6.3%, p < 0.05). MPC-SP group showed, however, lower inflammation (MPC-SP: 0.3 ± 0.26 vs. PLGA-EES: 1.2 ± 0.48, p < 0.05) and fibrin deposition (MPC-SP: 1.0 ± 0.73 vs. PLGA-EES: 1.5 ± 0.59, p < 0.05) around the stent strut. MPC-SP showed more increased expression of cluster of differentiation 31, suggesting enhanced re-endothelialization. CONCLUSION: Compared to PLGA-EES, MPC-SP demonstrated more decreased inflammation of the vascular wall and enhanced re-endothelialization and stent coverage. Hence, MPC-SP has the potential therapeutic benefits for the treatment of coronary artery disease by solving limitations of currently available DESs.

RESUMO

AIM: To determine the factors related with the perception of feeling safe during pre-hospital emergency care. METHODS: A multi-centred, cross-sectional study. Data collection from April 2021 to March 2022, in the Centro de Emergencias Sanitarias 061 (Andalusia, Spain). INCLUSION CRITERIA: witnesses of health care by emergency medical services. EXCLUSION CRITERIA: minors, or communication barriers. OUTCOME VARIABLE: Witness Perceived Safety Scale ESPT10. The variables studied were related with sociodemographic data, the request for health care, the patient, the hospital transfer and patient safety incidents. A multivariate linear regression model was constructed for the dependent variable. The study followed STROBE statement. RESULTS: Responses were obtained from 1400 witnesses. The linear regression model showed that the score on the scale increased as the witnesses felt more satisfied (B = 1.302; p < 0.001). On the contrary, the score was lower when the witness reported a patient safety incident (B = -2.856; p < 0.001 and B = -3.166; p < 0.001), or when the assistance took place in a public space (B = -0.722; p = 0.017). CONCLUSIONS: The level of satisfaction, the occurrence of a patient safety incident, and the place of health care are related factors with the perception of the witnesses. The Witness Perceived Safety Scale ESPT10 could be considered a valid and useful patient safety indicator.

RESUMO

Objetivos: Conocer los factores que se relacionan con la percepción de los pacientes de sentirse seguros en emergencias extrahospitalarias. Método: Estudio observacional descriptivo, transversal, multicéntrico, en los equipos de emergencias 061 de Andalucía. Se recogieron los datos desde abril 2021 hasta marzo 2022. Criterios de inclusión fueron pacientes asistidos y trasladados por equipos de emergencias, y los criterios de exclusión fueron menores de edad, deterioro cognitivo, alteración de consciencia, o barreras comunicativas. Se calculó un tamaño muestral mínimo de 644 sujetos. La variable resultado fue la puntuación de la Escala de Seguridad Percibida (ESP16). Se estudiaron variables sociodemográficas y relacionadas con la demanda asistencial, el paciente y el traslado. Además, se recogieron notificaciones de incidentes relacionados con la seguridad del paciente (IRSP). Se construyó un modelo de regresión lineal multivariable para la variable dependiente. Se siguieron las recomendaciones STROBE. Resultados: Se obtuvieron 1.756 respuestas. La puntuación media en la ESP16 fue 77,7 (DE 5,6), con mediana de 80. El modelo de regresión lineal mostró que el nivel de satisfacción (B = 2,799; p < 0,001), la notificación de error, caída, daño o lesión (B = –6,097; p < 0,001), la notificación de cualquier otro IRSP (B = –2,742; p < 0,001), la transferencia protocolizada (B = 2,538; p = 0,001), el tipo de recurso asistencial (B = 1,157; p < 0,001), un diagnóstico final cardiológico (B = 0,726; p = 0,014) y un nivel de dolor intenso (B = 1,195; p = 0,003) influían en la escala ESP16. Conclusiones: La percepción de seguridad del paciente es muy alta, y está condicionada por el nivel de satisfacción, la notificación de IRSP, la transferencia protocolizada, el recurso asistencial, el diagnóstico final y el nivel de dolor.

Aim: To identify factors related to patients’ feeling of safety during prehospital emergencies. Methods: Descriptive, multicenter cross-sectional study in the context of “061” emergency response services of Andalusia, Spain. Data were collected from April 2021 to March 2022. Patients attended and transported by emergency responders were eligible for inclusion. Patients were excluded if they were minors or in an altered state of consciousness, or had cognitive impairment or any barrier to communication. We calculated that a minimum sample size of 644 patients would be required. The outcome variable was the score on a 16-item scale of patient-perceived safety (ESP16, as abbreviated in Spanish). Sociodemographic, emergency service response, patient, and hospital transfer variables were studied in relation to ESP16 score. We also collected patient safety incident reports.Multivariate linear regression was used to analyze associations between the independent variables and the dependent outcome variable. Guidelines for Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) were followed. Results: We received 1756 responses. The mean (SD) ESP16 score was 77.7 (5.6); the median score was 80. The b coefficients derived from the linear regression model were as follows for the variables associated with the ESP16 score: 2.799 (P < .001) for satisfaction; –6.097 (P < .001) for incident reports of errors, falls, harm, or injury; –2.742 (P < .001) for reports of any other incident during attendance; 2.538 (P = .001) for use of the transport protocol; 1.157 (P < .001) for type of emergency transport used; 0.726 (P = .014) for a cardiology diagnosis; and 1.195 (P = .003) for pain intensity. Conclusions: Patients’ perception of safety is very high, as reflected by level of satisfaction, incident reports, use of a transport protocol, means of transport used, diagnosis, and pain level.

RESUMO

Fundamento. El objetivo de este estudioes compararlos resulta-dos obtenidos en escolares formados en RCP por progenitores en el ambiente familiar y por profesores en el ambiente educativo. Método. Estudio aleatorizado del aprendizaje de RCP en escolares de Educación Primaria (1º y 2º curso) de la Región de Murcia. Los progenitores (grupo familia, GF) y profesores (grupo maestros, GM) han participado como formadores a través de un material di-dáctico adaptado para escolares (un cuento y un vídeo de dibujos animados) de la serie educativa Jacinto y sus Amigos©. Se evaluaron ocho conocimientos y cinco habilidades prácticas.Resultados. Se seleccionaron 160 escolares y terminaron el estudio 116; el GF presentó 51,3% de pérdidas. Los escolares formados por el GM obtuvieron puntuaciones medianas significativamente ma-yores tanto en conocimiento teórico (6,7; RIC=1,8 vs 4,7; RIC=3,1; p<0,001) como en todas las habilidades prácticas a excepción de reconocer un situación de emergencia. En el GF, la enseñanza sobre RCP con un cuento y un vídeo de dibujos animados logró puntua-ciones significativamente mejores en cinco conocimientos y en cuatro habilidades que con solo un cuento.Conclusiones. La implementación de recursos educativos no tec-nológicos, cómo cuentos y dibujos animados, en la enseñanza de la RCP en escolares de primaria aumenta los conocimientos y habili-dades. Los escolares formados por los maestros en el ámbito edu-cativo han aprendido significativamente más que los formados por la familia y, dentro del ámbito familiar, la enseñanza sobre RCP fue más eficaz mediante un cuento y un vídeo de dibujos animados que cuando simplemente disponen del cuento (AU)


Background. We compared the outcome of training schoolchil-dren how to perform CPR by parents/legal guardians in the family environment versus by teachers at school.Methods. Randomized study of CPR learning in primary school children (1st and 2nd grades) in the Region of Murcia. Parents/legal guardians (family group) and teachers (teacher group) trained the children using didactic material adapted for that age population (one story and one cartoon video) from the educational series Jacinto y sus Amigos©. We evaluated eight theoretical knowledge questions and five practical skills.Results. One hundred and sixty schoolchildren were selected and 116 completed the study; in the family group, 51.3% did not fin-ish the study. Children trained by teachers obtained significantly higher median scores in comparison with the family group both in theoretical knowledge (6.7; IQR=1.8 vs 4.7; IQR=3.1, respective-ly; p < 0.001) and in all practical skills except for “recognizing an emergency situation”. Children in the family group, learning CPR with one story and one cartoon video achieved significantly better scores in five theoretical knowledge questions and four skills than with only the story.Conclusions. Using non-technological educational resources, e.g., stories and animated cartoons for teaching CPR to primary school students, increases their knowledge and skills. Schoolchildren trained in the educational environment acquired more knowledge and skills than those trained by parents. Within the family environ-ment, CPR teaching was more effective through one story and one cartoon video than when only the story was used (AU)

RESUMO

BACKGROUND: We compared the outcome of training schoolchildren how to perform CPR by parents/legal guardians in the family environment versus by teachers at school. METHODS: Randomized study of CPR learning in primary school children (1st and 2nd grades) in the Region of Murcia. Parents/legal guardians (family group) and teachers (teacher group) trained the children using didactic material adapted for that age population (one story and one cartoon video) from the educational series Jacinto y sus Amigos©. We evaluated eight theoretical knowledge items and five practical skills. RESULTS: One hundred and sixty schoolchildren were selected and 116 completed the study; in the family group, 51.3% did not finish the study. Children trained by teachers obtained significantly higher median scores in comparison with the family group both in theoretical knowledge (6.7; IQR=1.8 vs 4.7; IQR=3.1, respectively; p < 0.001) and in all practical skills except for "recognizing an emergency situation". Children in the family group, learning CPR with one story and one cartoon video achieved significantly better scores in five theoretical knowledge items and four skills than with only the story. CONCLUSIONS: Using non-technological educational resources, e.g., stories and animated cartoons for teaching CPR to primary school students, increases their knowledge and skills. Schoolchildren trained in the educational environment acquired more knowledge and skills than those trained by parents. Within the family environment, CPR teaching was more effective through one story and one cartoon video than when only the story was used.
