ABSTRACT
OBJECTIVE: To identify how stress measured by salivary cortisol during clinical simulation-based education, or simulation and another teaching method, impacts performance. METHOD: Systematic review of the association between cortisol and performance in simulations. The following databases were used: PubMed, LIVIVO, Scopus, EMBASE, Latin American and Caribbean Health Sciences Literature (LILACS) and Web of Science. Additional searches of gray literature were carried out on Google Scholar and Proquest. The searches took place on March 20, 2023. The risk of bias of randomized clinical trials was assessed using the Cochrane Collaboration Risk of Bias Tool (RoB 2). Inclusion criteria were: simulation studies with salivary cortisol collection and performance evaluation, published in any period in Portuguese, English and Spanish. RESULTS: 11 studies were included which measured stress using salivary cortisol and were analyzed using descriptive synthesis and qualitative analysis. CONCLUSION: Some studies have shown a relationship between stress and performance, which may be beneficial or harmful to the participant. However, other studies did not show this correlation, which may not have been due to methodological issues.

OBJECTIVE: to analyze the effectiveness of peripherally inserted central catheter insertion techniques in preventing the occurrence of complications related to this device in newborns. METHOD: a paired and network systematic literature review and meta-analysis, with its search carried out in seven databases and in the Grey Literature, including randomized and non-randomized clinical trials. The risk of bias was assessed using the Cochrane Risk of Bias 2 and Risk of Bias In Non-randomized Studies of Interventions tools. Certainty of the evidence was assessed by means of the Grading of Recommendations Assessment, Development and Evaluation. A meta-analysis was carried out with the aid of the R statistical program. RESULTS: eight studies with 1,126 newborns were included and six insertion techniques were identified: intracavitary electrocardiogram; intracavitary electrocardiogram associated with ultrasound; ultrasound; formula; anatomical landmark; and modified anatomical landmark. Five techniques significantly decreased primary tip malpositioning when compared to the control ( p <0.05). Intracavitary electrocardiogram significantly and more effectively reduced arrhythmias, general complications and phlebitis; the technique that used a formula also reduced general complications. Infection, infiltration, secondary tip malpositioning, catheter rupture, thrombosis, occlusion and catheter-associated skin lesion were not significantly preventable events. CONCLUSION: intracavitary electrocardiogram and use of the formula were the most effective techniques in reducing complications.

Introdução: As Disfunções temporomandibulares (DTM) incluem desordens dos músculos da mastigação, das articulações temporomandibulares e da inervação local, frequentemente associadas a dor orofacial e que resultam em mioartropatias do Sistema Mastigatório. A tendência atual tende a começar com tratamento conservador e progredir a procedimentos mais invasivos na falha dos tratamentos iniciais. Relato de caso: O presente relato visa mostrar o resultado de uma técnica invasiva para o tratamento de uma DTM grave, com a aplicação do ácido hialurônico e de corticoide através de uma punção guiado por ultrassonografia. A paciente apresentava dor crônica e perda importante de peso devido a limitação da abertura da boca. A RM demonstrou disfunção das ATMs, com sinais de deslocamento parcial do disco direito anteromedialmente. Foi realizada a aplicação bilateral intra-articular de ácido hialurônico e de corticoide através de uma punção guiado por ultrassonografia. Considerações Finais: A associação destas classes na punção de ATMs ainda não está bem estabelecida havendo necessidade de estudos complementares para avaliar eficácia, como este relato de caso, que se mostrou favorável com grande melhora clínica da paciente...

Introduction: Temporomandibular dysfunctions (TMD) include disorders of the masticatory muscles, temporomandibular joints, and local innervation, often associated with orofacial pain and resulting in myoarthropathies of the masticatory system. The current trend tends to begin with conservative treatment and progress to more invasive procedures if the initial treatments fail. Case Report: The present report aims to show the result of an invasive technique for the treatment of a severe TMD, with the application of hyaluronic acid and corticoid through an ultrasound-guided puncture. The patient presented with chronic pain and significant weight loss due to limited mouth opening. MRI demonstrated TMJ dysfunction, with signs of partial anteromedial dislocation of the right disc. Bilateral intra-articular application of hyaluronic acid and corticoid was performed through an ultrasound guided puncture.

OBJECTIVE: to assess nursing students' emotions undergoing maternal-child clinical simulation. METHODS: an observational study, carried out between June and July 2019. The Focus Group technique was used, with 28 nursing students, randomly distributed into three groups, with qualitative (Bardin technique) and quantitative data (Artificial Intelligence) analysis, to analyze emotions through facial expressions, tone of voice and description of speeches. RESULTS: we defined two categories: "It was not easy, it was very stressful"; and "Very valuable experience". In Artificial Intelligence, emotional distribution between face, voice and speech revealed a prevalence of negative valence, medium-high degree of passivity, medium power to control the situation and medium-high degree of obstruction in task accomplishment. FINAL CONSIDERATIONS: this study revealed an oscillation between positive and negative emotions, and shows to the importance of recognizing them in the teaching-learning process in mother-child simulation.

The aims of this study were to perform pre-surgery miRNA profiling of patients who develop Vasoplegic syndrome (VS) after coronary artery bypass grafting (CABG) and identify those miRNAs that could be used as VS prognostic tools and biomarkers. The levels of 754 microRNAs (miRNAs) were measured in whole blood samples from a cohort of patients collected right before the coronary artery bypass grafting (CABG) surgery. We compared the miRNA levels of those who developed VS (VASO group) with those who did not (NONVASO group) after surgery. Six miRNAs (hsa-miR-548c-3p, -199b-5p, -383-5p -571 -183-3p, -30d-5p) were increased and two (hsa-1236-3p, and hsa-miR770-5p) were decreased in blood of VASO compared to NONVASO groups. Receiver Operating Characteristic (ROC) curve analysis revealed that a combination of the miRNAs, hsa-miR-30d-5p and hsa-miR-770-5p can be used as VS predictors (AUC = 0.9615, p < 0.0001). The computational and functional analyses were performed to gain insights into the potential role of these dysregulated miRNAs in VS and have identified the "Apelin Liver Signaling Pathway" as the canonical pathway containing the most target genes regulated by these miRNAs. The expression of the combined miRNAs hsa-miR-30d and hsa-miR-770-5p allowed the ability to distinguish between patients who could and could not develop VS, representing a potential predictive biomarker of VS.

ABSTRACT
AIMS: Optimize the production of Aspergillus brasiliensis endoglucanase in a solid-phase bioprocess using cupuaçu shell as substrate. METHODS AND RESULTS: The shells were supplemented with nitrogen and phosphorous and used as a substrate. The centesimal and inorganic composition of the residue was determined, and found to be rich in fibres, and possessed essential elements for fungal growth. In the initial cultivation of A. brasiliensis, endoglucanase activity of 7.35 U g-1 was obtained. A factorial experimental design was used to determine the most significant variables for the bioprocess. The interactions between moisture, temperature and nitrogen source were noteworthy (p < 0.05). From the rotational central composite design, the optimization of temperature and nitrogen supplementation was obtained, and this reached 40.50 U g-1 , which is an increase of more than five times the value obtained initially. The enzymatic extract was applied as the biocatalyst in the hydrolysis of cupuaçu shells and, after 48 h, it was possible to observe the production of reducing sugars. CONCLUSIONS: Cupuaçu shell can be used as a substrate for endoglucanase production by A. brasiliensis. The process was optimized for the cultivation temperature and the nitrogen source. The enzymatic extract can be applied in the hydrolysis of lignocellulosic biomass. SIGNIFICANCE AND IMPACT OF THE STUDY: Cupuaçu shells can be used to produce cellulases, a product of high added value that can generate economic and environmental benefits for communities and companies producing derivatives of the cupuaçu fruit.

ABSTRACT
ABSTRACT Purpose: to compare the effect of two tongue coupling approaches on the electrical activity of the suprahyoid musculature in young women. Methods: the sample comprised 47 women aged 18 to 27 years, distributed into groups, according to exercise training time - 10 and 15 seconds. They answered an initial questionnaire and were submitted to speech-language-hearing clinical assessment, body mass index calculation, and electromyographic assessment. Two electrodes were positioned bilaterally on the skin in the region of the suprahyoid musculature to pick up the electromyographic signal. The women performed the tests with resting periods and maximum voluntary contraction, coupling the tongue with the hard palate as strongly as possible, followed by three training series coupling the tongue with the palate. The collected data regarding amplitude and frequency of the myoelectrical activity were analyzed, by comparing the performance within the two groups and one another with the Friedman and One-Way ANOVA tests, and Mann-Whitney U test, at the 5% significance level. Results: no statistical significance was observed between the groups when comparing their performance in the series, neither was there any decrease in the median frequency in each group while performing the three series. Conclusion: no effect on the electrical activity of the suprahyoid musculature was found in young women when they performed isometric tongue coupling exercise training.

ABSTRACT
BACKGROUND: Worldwide, patient safety has been a widely discussed topic and has currently become one of the greatest challenges for health institutions. This concern is heightened when referring to children. OBJECTIVE: The goal of this study was to develop a virtual learning environment for medication administration, as a tool to facilitate the training process of undergraduate nursing students. METHODS: Descriptive research and methodological development with a quantitative and qualitative approach were used with stages of design-based research as methodological strategies. For the development of the virtual environment, 5 themes were selected: rights of medication administration, medication administration steps, medication administration routes, medication calculation, and nonpharmacological actions for pain relief. After development, 2 groups-expert judges in the field of pediatrics and neonatology for environment validation and undergraduate nursing students for the assessment-were used to assess the virtual learning environment. For the validation of the virtual learning environment by expert judges, the content validity index was used, and for the evaluation of the students, the percentage of agreement was calculated. RESULTS: The study included 13 experts who positively validated the virtual environment with a content validity index of 0.97, and 26 students who considered the content suitable for nursing students, although some adjustments are necessary. CONCLUSIONS: The results show the benefit of the virtual learning environment to the training of nursing students and professional nurses who work in health care. It is an effective educational tool for teaching medication administration in pediatrics and neonatology and converges with the conjectures of active methodologies.
ABSTRACT
Chagas disease discovered more than a century ago remains an incurable disease. The objective of this work was to investigate the therapeutic potential of cardiomyocytes derived from mouse embryonic stem cells (CM-mESC) in a model of chronic Chagasic cardiomyopathy (CCC). Mouse embryonic stem cells (mESC) were characterized, transduced with luciferase, and submitted to cardiac differentiation. CM-mESC were labeled with superparamagnetic iron oxide particles. To induce CCC, mice were infected with Brazil strain trypomastigotes. At 150 days post-infection (dpi), infected animals were treated with CM-mESC or PBS. Cells were detected by magnetic resonance imaging (MRI) and bioluminescence. Cardiac function was evaluated by MRI and electrocardiogram at 150 and 196 dpi. CCC mice showed significant differences in MRI and ECG parameters compared to non-infected mice. However, no differences were observed in contractile and electrical parameters between cell and PBS injected groups, 45 days after cell transplantation. Cells were detected 24 h after transplantation by MRI. CM-mESC bioluminescence tracking demonstrated over 90% decrease in signal 8 days after treatment. Nevertheless, the Infected + CM-mESC group showed a significant reduction in the percentage of collagen fibers when compared to the Infected + PBS group. In conclusion, CM-mESC therapy was not effective in reversing cardiac functional changes induced by Chagas disease despite some improvement in myocardial fibrosis.

Background: The failure to translate preclinical results to the clinical setting is the rule, not the exception. One reason that is frequently overlooked is whether the animal model reproduces distinctive features of human disease. Another is the reproducibility of the method used to measure treatment effects in preclinical studies. Left ventricular (LV) function improvement is the most common endpoint in preclinical cardiovascular disease studies, while echocardiography is the most frequently used method to evaluate LV function. In this work, we conducted a robust echocardiographic evaluation of LV size and function in dogs chronically infected by Trypanosoma cruzi. Methods and Results: Echocardiography was performed blindly by two distinct observers in mongrel dogs before and between 6 and 9 months post infection. Parameters analyzed included end-systolic volume (ESV), end-diastolic volume (EDV), ejection fraction (EF), and fractional shortening (FS). We observed a significant LVEF and FS reduction in infected animals compared to controls, with no significant variation in volumes. However, the effect of chronic infection in systolic function was quite variable, with EF ranging from 17 to 66%. Using the cut-off value of EF ≤ 40%, established for dilated cardiomyopathy (DCM) in dogs, only 28% of the infected dogs were affected by the chronic infection. Conclusions: The canine model of CCC mimics human disease, reproducing the percentage of individuals that develop heart failure during the chronic infection. It is thus mandatory to establish inclusion criteria in the experimental design of canine preclinical studies to account for the variable effect that chronic infection has on systolic function.
