Relationship between Static Lung Compliance and Extubation Failure in Postoperative Cardiac Surgery Patients. / Relação entre a Complacência Pulmonar Estática e a Falha de Extubação em Pacientes Pós-Operatório de Cirurgia Cardíaca.

BACKGROUND: Static lung compliance, which is seriously affected during surgery, can lead to respiratory failure and extubation failure, which is little explored in the decision to extubate after cardiac surgery. OBJECTIVE: To evaluate static lung compliance in the postoperative period of cardiac surgery and relate its possible reduction to cases of extubation failure in patients submitted to the fast-track method of extubation. METHODS: Patients undergoing cardiac surgery using cardiopulmonary bypass (CPB) at a state university hospital admitted to the ICU under sedation and residual block were included. Their static lung compliance was assessed on the mechanical ventilator using software that uses least squares fitting (LSF) for measurement. Within 48 hours of extubation, the patients were observed for the need for reintubation due to respiratory failure. The level of significance adopted for the statistical tests was 5%, i.e., p<0.05. RESULTS: 77 patients (75.49%) achieved successful extubation and 25 (24.51%) failed extubation. Patients who failed extubation had lower static lung compliance compared to those who succeeded (p<0.001). We identified the cut-off point for compliance through analysis of the Receiver Operating Characteristic Curve (ROC), with the cut-off point being compliance <41ml/cmH2O associated with a higher probability of extubation failure (p<0.001). In the multiple regression analysis, the influence of lung compliance (divided by the ROC curve cut-off point) was found to be 9.1 times greater for patients with compliance <41ml/cmH2O (p< 0.003). CONCLUSIONS: Static lung compliance <41ml/cmH2O is a factor that compromises the success of extubation in the postoperative period of cardiac surgery.

FUNDAMENTO: Pouco explorada na decisão de extubação no pós-operatório de cirurgia cardíaca, a complacência pulmonar estática seriamente afetada no procedimento cirúrgico pode levar à insuficiência respiratória e à falha na extubação. OBJETIVO: Avaliar a complacência pulmonar estática no pós-operatório de cirurgia cardíaca e relacionar sua possível redução aos casos de falha na extubação dos pacientes submetidos ao método fast-track de extubação. MÉTODOS: Foram incluídos pacientes que realizaram cirurgia cardíaca com uso de circulação extracorpórea (CEC) em um hospital universitário estadual admitidos na UTI sob sedação e bloqueio residual. Tiveram sua complacência pulmonar estática avaliada no ventilador mecânico por meio do software que utiliza o least squares fitting (LSF) para a medição. No período de 48 horas após a extubação os pacientes foram observados respeito à necessidade de reintubação por insuficiência respiratória. O nível de significância adotado para os testes estatísticos foi de 5%, ou seja, p<0,05. RESULTADOS: Obtiveram sucesso na extubação 77 pacientes (75,49%) e falharam 25 (24,51%). Os pacientes que falharam na extubação tiveram a complacência pulmonar estática mais baixa quando comparados aos que tiveram sucesso (p<0,001). Identificamos o ponto de corte para complacência por meio da análise da curva Receiver Operating Characteristic Curve (ROC) sendo o ponto de corte o valor da complacência <41ml/cmH2O associado com maior probabilidade de falha na extubação (p<0,001). Na análise de regressão múltipla, verificou-se a influência da complacência pulmonar (dividida pelo ponto de corte da curva ROC) com risco de falha 9,1 vezes maior para pacientes com complacência <41ml/cmH2O (p< 0,003). CONCLUSÕES: A complacência pulmonar estática <41ml/cmH2O é um fator que compromete o sucesso da extubação no pós-operatório de cirurgia cardíaca.

Effect of the hybridization of social and personal responsibility model and sport education model on physical fitness status and physical activity practice.

Physical activity patterns, sedentary habits and obesity levels among children and teenagers are indicators of a worrying reality which has been aggravated by the COVID-19 pandemic. In this context, this study has analysed the impact that new methodologies in Physical Education have on physical health aspects. Two teaching methods, namely, Teaching Personal and Social Responsibility and Sport Education Model, were hybridized, in a Secondary School in Murcia (Spain). Controlled quasi-experimental research was completed with a sample of 76 Secondary Education students aged 12-14 (male: 32; female: 44), developing a hybridization of both models in the experimental group. The Physician-based Assessment and Counselling for Exercise (PACE) questionnaire and Eurofit and Alpha Fitness motor tests were run to collect the results. Those showed significant improvement in standing long jump and speed-agility results in the control group. In the experimental group, on the contrary, no significant improvement was registered for either test, but out-of-school physical activity rates were higher. Following this research, it is concluded that both models have positive influence on physical activity habits, but the teaching time devoted to the subject of Physical Education is not enough to improve them.

Trial design of the MOTheR HDx study: a multicenter, open-label, prospective, randomized study to explore the morbidity and mortality in patients dialyzed with the Theranova HDx in comparison with online hemodiafiltration.

Background: Dialysis patients have been maintaining a high rate of cardiovascular morbidity and mortality. For this reason, it is to introduce necessary new technical advances in clinical practice. There is a relation between toxins retention and inflammation, mortality and morbidity. Medium cut-off (MCO) membranes are a new generation of membranes that allow the removal of a greater number of medium-sized molecules compared with high-flux hemodialysis (HF-HD), but retaining albumin. MCO membranes have an increased permeability and the presence of internal filtration. Because of these special properties, MCO generated a new concept of therapy called expanded HD (HDx). Until now, online hemodiafiltration (OL-HDF) has demonstrated its superiority, in terms of survival, compared with HF-HD. However, the comparison between OL-HDF and HDx remains an unsolved question. Methods: The MOTheR HDx study trial (NCT03714386) is an open-label, multicenter, prospective, 1:1 randomized, parallel-group trial designed to evaluate the efficacy and safety of HDx compared with OL-HDF in patients treated for dialysis in Spain for up to 36 months. The main endpoint is to determinate whether HDx is non inferior to OL-HDF at reducing the combined outcome of all-cause death and stroke (ischemic or hemorrhagic), acute coronary syndrome (angina and myocardial infarction), peripheral arterial disease (amputation or revascularization) and ischemic colitis (mesenteric thrombosis). Results: The trial has already started.

A Bidens pilosa L. Non-Polar Extract Modulates the Polarization of Human Macrophages and Dendritic Cells into an Anti-Inflammatory Phenotype.

Different communities around the world traditionally use Bidens pilosa L. for medicinal purposes, mainly for its anti-inflammatory, antinociceptive, and antioxidant properties; it is used as an ingredient in teas or herbal medicines for the treatment of pain, inflammation, and immunological disorders. Several studies have been conducted that prove the immunomodulatory properties of this plant; however, it is not known whether the immunomodulatory properties of B. pilosa are mediated by its ability to modulate antigen-presenting cells (APCs) such as macrophages (MØs) and dendritic cells (DCs) (through polarization or the maturation state, respectively). Different polar and non-polar extracts and fractions were prepared from the aerial part of B. pilosa. Their cytotoxic and immunomodulatory effects were first tested on human peripheral blood mononuclear cells (PBMCs) and phytohemagglutinin (PHA)-stimulated PBMCs, respectively, via an MTT assay. Then, the non-cytotoxic plant extracts and fractions that showed the highest immunomodulatory activity were selected to evaluate their effects on human MØ polarization and DC maturation (cell surface phenotype and cytokine secretion) through multiparametric flow cytometry. Finally, the chemical compounds of the B. pilosa extract that showed the most significant immunomodulatory effects on human APCs were identified using gas chromatography coupled with mass spectrometry. The petroleum ether extract and the ethyl acetate and hydroalcoholic fractions obtained from B. pilosa showed low cytotoxicity and modulated the PHA-stimulated proliferation of PBMCs. Furthermore, the B. pilosa petroleum ether extract induced M2 polarization or a hybrid M1/M2 phenotype in MØs and a semi-mature status in DCs, regardless of exposure to a maturation stimulus. The immunomodulatory activity of the non-polar (petroleum ether) extract of B. pilosa on human PBMC proliferation, M2 polarization of MØs, and semi-mature status in DCs might be attributed to the low-medium polarity components in the extract, such as phytosterol terpenes and fatty acid esters.

Epidemiology and disease burden of patients requiring neurocritical care: a Brazilian multicentre cohort study.

Acute neurological emergencies are highly prevalent in intensive care units (ICUs) and impose a substantial burden on patients. This study aims to describe the epidemiology of patients requiring neurocritical care in Brazil, and their differences based on primary acute neurological diagnoses and to identify predictors of mortality and unfavourable outcomes, along with the disease burden of each condition at intensive care unit admission. This prospective cohort study included patients requiring neurocritical care admitted to 36 ICUs in four Brazilian regions who were followed for 30 days or until ICU discharge (Aug-Sep in 2018, 1 month). Of 4245 patients admitted to the participating ICUs, 1194 (28.1%) were patients with acute neurological disorders requiring neurocritical care and were included. Patients requiring neurocritical care had a mean mortality rate 1.7 times higher than ICU patients not requiring neurocritical care (17.21% versus 10.1%, respectively). Older age, emergency admission, higher number of potential secondary injuries, and worse APACHE II, SAPS III, SOFA, and Glasgow coma scale scores on ICU admission are independent predictors of mortality and poor outcome among patients with acute neurological diagnoses. The estimated total DALYs were 4482.94 in the overall cohort, and the diagnosis with the highest DALYs was traumatic brain injury (1634.42). Clinical, epidemiological, treatment, and ICU outcome characteristics vary according to the primary neurologic diagnosis. Advanced age, a lower GCS score and a higher number of potential secondary injuries are independent predictors of mortality and unfavourable outcomes in patients requiring neurocritical care. The findings of this study are essential to guide education policies, prevention, and treatment of severe acute neurocritical diseases.

FINAL CONSIDERATIONS: in the perception of nurses, supervision influences quality indicators in nursing care.

Postoperative Period of Myocardial Revascularization Surgery: Retrospective Cohort Study of a Single Center.

INTRODUCTION: Risk factors and postoperative complications can worsen the condition of patients undergoing coronary artery bypass grafting; some of these factors and complications are closely related to mortality rate. OBJECTIVE: To describe clinical factors and outcomes related to mortality of patients undergoing coronary artery bypass grafting and on invasive mechanical ventilation. METHODS: This is a single-center retrospective data analysis of patients who underwent coronary artery bypass grafting on invasive mechanical ventilation between 2013 and 2019. Data regarding clinical characteristics, postoperative complications, intensive care unit and mechanical ventilation time, and their relationship with mortality were analyzed. RESULTS: Four hundred seventy-two patients who underwent coronary artery bypass grafting entered the study. Their mean age was 62.3 years, and mean body mass index was 27.3. The mortality rate was 4%. Fifty percent of the patients who had ventilator-associated pneumonia died. Considering the patients who underwent hemotherapy and hemodialysis, 20% and 33% died, respectively. Days of intensive care unit stay and high Acute Physiology and Chronic Health Evaluation score and Simplified Acute Physiology Score were significantly related to death. CONCLUSION: Factors and clinical conditions such as the patients' age, associated comorbidities, the occurrence of ventilator-associated pneumonia, length of stay in the intensive care unit, and mechanical ventilation time are related to higher mortality in patients undergoing coronary artery bypass grafting.

Relative enhancement index can be used to quantify liver function in cirrhotic patients that undergo gadoxetic acid-enhanced MRI.

OBJECTIVES: To evaluate MRI with gadoxetic acid to quantify liver function in cirrhotic patients using the relative enhancement index (REI) compared with Child-Pugh score (CPS), MELD score, and indocyanine green plasma disappearance rate (ICG-PDR) and to establish cutoffs for REI to stratify cirrhotic patients into good and poor liver function groups. METHODS: We prospectively evaluated 60 cirrhotic patients and calculated CPS, MELD score, ICG-PDR, and REI for each patient. Spearman's correlation coefficient was used to assess correlation between REI, CPS, MELD, and ICG-PDR. Good and poor liver function groups were created by k-means clustering algorithm using CPS, MELD, and ICG-PDR. ROC curve analysis was performed and optimal cutoff was identified for group differentiation. RESULTS: Good correlations were found between REI and other liver function biomarkers: REI and CPS (rho = - 0.816; p < 0.001); REI and MELD score (rho = - 0.755; p < 0.001); REI and ICG-PDR (rho = 0.745; p < 0.001)]. REI correlation was stronger for patients with Child-Pugh A (rho = 0.642, p = 0.002) and B (rho = 0.798, p < 0.001) than for those with Child-Pugh C (rho = 0.336, p = 0.148). REI is significantly lower in patients with poor liver function (p < 0.001). ROC curve showed an AUC 0.94 to discriminate patients with poor liver function (REI cutoff < 100; 100% sensitivity; 76% specificity). CONCLUSIONS: REI is a valuable non-invasive index for liver function quantification that has good correlations with other liver function biomarkers. REI can be easily calculated and can be used to estimate liver function in clinical practice in the routine evaluation of cirrhotic patients that undergo MR imaging with gadoxetic acid contrast. KEY POINTS: • REI is a valuable non-invasive index for liver function quantification that has good correlations with other liver function biomarkers. • REI can be easily calculated in the routine evaluation of cirrhotic patients that undergo gadoxetic acid-enhanced MRI. • The REI enables stratification of cirrhotic patients into good and poor liver function groups and can be used as additional information, together with morphological and focal liver lesion evaluation.

Riesgo cardiovascular en pacientes recuperados de COVID-19 a corto y mediano plazo: ¿qué concluye la evidencia actual?

El riesgo y enfermedades cardiovasculares en pacientes recuperados de COVID-19 es un campo de análisis reciente en la literatura médica mundial y de vital importancia, porque existe una gran cantidad de pacientes con complicaciones una vez terminada la fase aguda de la enfermedad. El gran espectro del daño al miocardio en esta enfermedad puede variar desde una elevación asintomática de los niveles de troponinas cardíacas, hasta la aparición de una miocarditis fulminante y/o shock circulatorio, lo que puede dejar secuelas significativas. A pesar de que no existe una estrategia clara para abordar los eventos cardíacos que aparecen durante la COVID-19, y teniendo en cuenta que el manejo se hace principalmente para controlar los síntomas del paciente a medida que surgen, el objetivo de este trabajo fue conocer y recopilar la evidencia actual en esta temática, de tal manera que se pueda ofrecer al lector una guía de consulta en español que contribuya al desarrollo de su profesión sanitaria. La metodología utilizada fue una búsqueda de literatura en bases de datos como Medline, Scopus, Science Direct, con una ventana de tiempo entre 2019 y 2022. Los principales resultados revelaron que dentro de los mecanismos moleculares y fisiopatológicos implicados en este síndrome pos-COVID, se encuentra la afectación del sistema renina-angiotensina-aldosterona, al estar ligado el tropismo del SARS-Cov-2 a la enzima convertidora de angiotensina 2. Esto ocasiona una alteración de la respuesta neuro-humoral del sistema cardiovascular, renal y digestivo, lo que genera déficit en las vías de señalización y ocasiona lesión directa sobre corazón, pulmones y otros órganos. El síndrome pos-COVID-19, en general, se define como la aparición o persistencia de los síntomas posteriores a 3 o 4 semanas de aparecida la fase aguda de la enfermedad. Entonces, esta podría considerarse como una ventana de tiempo de riesgo y seguimiento estricto, para valorar de forma personalizada el riesgo entre los distintos grupos de pacientes, sobre todo de aquellos con antecedentes personales de enfermedad cardiovascular. Los principales resultados revelaron la presencia de trastornos como la insuficiencia cardiaca, las arritmias, la pericarditis y la miocarditis, que requieren de detección precoz y que se presentan días e incluso semanas posteriores a la fase aguda de la COVID-19.

Cardiovascular risk and diseases among patients recovered from COVID-19 is a recent field of study in the world medical literature and is also of vital importance because a large number of patients develop complications once the acute phase of the disease is over. The broad spectrum of myocardial injury in cardiovascular diseases can range from the asymptomatic elevation of cardiac troponin levels to the development of fulminant myocarditis and/or circulatory shock, which can leave significant sequelae. Despite the fact that there is no clear strategy to treat cardiac events that occur during COVID-19 infection and taking into account that treatment is mainly aimed at relieving patients' symptoms as they arise, the objective of this work was to find out and collect current evidence on this subject, so that readers can be offered a reference guide in Spanish that contributes to the development of their health profession. The methodology used was a literature search in databases including Medline, Scopus and ScienceDirect within a time window between 2019 and 2022. The main results revealed that the molecular and pathophysiological mechanisms involved in post-COVID-19 syndrome include the renin-angiotensin-aldosterone system since SARS-CoV-2 tropism is linked to angiotensin-converting enzyme 2. This causes an alteration of the neurohumoral response of the cardiovascular, renal and digestive systems, generating deficits in the signaling pathways and causing direct damage to the heart, lungs and other organs. PostCOVID-19 syndrome, in general, is defined as the occurrence or persistence of symptoms three or four weeks after the acute phase of the disease. This could then be considered as a time window of risk and strict follow-up to assess in a personalized way the risk among the different groups of patients, especially those with a past history of cardiovascular disease. The main results revealed disorders such as heart failure, arrhythmias, pericarditis and myocarditis, which require early detection and occur days or even weeks after the acute phase of COVID-19.

Relapsing-remitting and primary progressive multiple sclerosis treated with ocrelizumab: A comparative study.

OBJECTIVES: To compare the clinical and radiological effectiveness of ocrelizumab in primary progressive multiple sclerosis (PPMS) and relapsing-remitting multiple sclerosis (RRMS) in a clinical practice setting and describe its tolerability and adverse events. METHODS: A retrospective observational cohort study was conducted comparing clinical and magnetic resonance imaging (MRI) data of all patients with (pw)PPMS and RRMS who had received treatment with ocrelizumab at least one cycle and have been followed up for one year at minimum. RESULTS: 42 patients (27 women) treated with ocrelizumab: 29 had RRMS and 13 PPMS. The follow-up period was 26.4 ± 8.4 months. The proportion of pwRRMS with no evidence of disease activity (NEDA) in the first year was 69.2% and in the second was 80%. In the first year, radiological activity was reduced by 80.0% in pwRRMS and 91.7% in pwPPMS. In the second year, radiological activity was completely reduced in both groups. A statistically significant difference (p<0.05) was observed between the pre-ocrelizumab rate of disability progression vs. the first year rate of progression for pwRRMS and pwPPMS. However, an increase in the disability progression rate in the second year of treatment was found in pwPPMS. Ocrelizumab was mostly well tolerated and some adverse effects were reported: infusion-related reactions (IRRs) were the most frequent adverse event, followed by infections and hematological side effects. Discontinuations were due to infections, hematological complications, and perception of ineffectiveness. CONCLUSIONS: Ocrelizumab was very effective in reducing relapses and MRI activity. The rate of progression was slowed down; however, the effect was more evident for pwRRMS than for pwPPMS over time.

Ecological Aspects of the Phlebotominae Fauna (Diptera: Psychodidae) among Forest Fragments and Built Areas in an Endemic Area of American Visceral Leishmaniasis in João Pessoa, Paraíba, Brazil.

Sand flies are dipterans of medical importance, as some species are vectors of American visceral leishmaniasis (AVL). The municipality of João Pessoa (Paraíba, northeastern Brazil), is an endemic region for AVL, having high rates of human and canine cases. The main objective was to evaluate the sand fly fauna among forest fragments and built areas, and its relationship with environmental conditions. HP light traps were placed in the studied areas from March 2019 to July 2021. A total of 2141 specimens of phlebotomines were captured, comprising nine genera and ten species. Temperature and humidity were significant and positive only in built areas. The diversity composition among forest fragments and built areas was different and the AVL vector, Lutzomyia longipalpis, was the most prevalent species in built areas. The study showed that the built areas present differences in their richness and diversity of sand flies in relation to forest fragments, concluding that the conservation of forest areas, even if urban fragments, favors the diversity of phlebotomine species.

Competências Emocionais nos Enfermeiros de Saúde Mental: Contributos da implementação de um modelo de supervisão clínica / Emotional Competences in Mental Health Nurses: Contributions of a clinical supervision model implementation / Competencias Emocionales en Enfermeros de Salud Mental: Aportaciones a la implementación de un modelo de supervisión clínica

Resumo Contexto: A Competência Emocional (CE) é definida como um conjunto de conhecimentos, capacidades, habilidades e atitudes necessárias para compreender, expressar e regular de forma apropriada os fenómenos emocionais, bem como realizar diversas atividades com elevado nível de qualidade e eficácia. No contexto de Saúde Mental, esta competência assume relevância pela sua natureza inerente ao exercício profissional, com ação privilegiada a nível das competências interpessoais e relação terapêutica. O desenvolvimento e implementação destas competências no contexto da prática, permite aumentar os ganhos para a organização, cliente de cuidados e saúde mental dos enfermeiros. Existem poucos estudos que avaliam a utilização da supervisão clínica como estratégia de suporte formal para o desenvolvimento destas competências nos enfermeiros quer a nível do contexto da formação inicial ou contínua. Objetivo: Avaliar a implementação do Modelo SafeCare no desenvolvimento de competências emocionais nos enfermeiros de um serviço de Saúde Mental. Métodos: Estudo misto caracterizado pela triangulação concomitante, contemplando um estudo quantitativo descritivo, seguido de realização de entrevistas semiestruturadas. Resultados: Não existem diferenças estatisticamente significativas entre os dois momentos. Na análise de conteúdo efetuada, os enfermeiros identificam mudanças positivas ao nível do seu desenvolvimento pessoal e profissional, comunicação em equipa, gestão de conflitos e dos relacionamentos em grupo. Reportam ainda alterações na qualidade de cuidados e na organização. Conclusões: A implementação do Modelo SafeCare mostrou ter contribuído para o desenvolvimento das competências emocionais nos enfermeiros num contexto de Saúde Mental, contudo, futuros estudos serão necessários para aprofundar a eficácia da implementação do modelo.

Abstract Background: Emotional Competence (EC) is defined as a set of knowledge, skills, abilities and attitudes necessary to understand, express and adequately regulate emotional phenomena, as well as perform various activities with a high level of quality and effectiveness. This competence is highly relevant in mental health environments, strongly influencing interpersonal competencies and the therapeutic relationship. The development and implementation of these competencies in clinical practice produces gains to the organization, patient and nurses' mental health. There are few studies assessing clinical supervision as a formal support strategy to the development of these competencies in nurses either at an initial or continuing training. Aim: To evaluate the implementation of the SafeCare Model in the development of the emotional competence of nurses of a Mental Health service. Methods: Mixed study characterized by concomitant triangulation, including a descriptive quantitative study, followed by semi-structured interviews. Results: No statistically significant differences were found between the two moments. In the content analysis nurses identified positive changes in their personal and professional development, team communication, conflict management and relationships between groups. They also reported changes in the quality of care and in the organizations. Conclusions: The implementation of the SafeCare Model has very likely contributed to the development of nurses' emotional competence in a Mental Health context. However, further research is needed to improve efficacy of the model implementation.

Resumen Contexto: De la Competencia Emocional (CE) forman parte un conjunto de conocimientos, capacidades, habilidades y actitudes necesarias para comprender, expresar y controlar de forma adecuada aspectos emocionales, así como realizar distintas actividades con un gran nivel de eficacia. De acuerdo con la Salud Mental, esta competencia adquiere importancia por su naturaleza inherente al ejercicio profesional, con acción privilegiada a nivel de las relaciones interpersonales y relaciones terapéuticas. El desarrollo y la implementación de esas competencias en perspectiva práctica, permite mejorar la organización, los cuidados con el enfermo y la salud mental de los enfermeros. Hay pocos estudios que evalúan la supervisión clínica como proceso regulable para el desarrollo de las destrezas en los enfermeros en un nivel inicial y en un nivel avanzado. Objetivo(s): Evaluar la eficacia del Modelo SafeCare en el desarrollo de las competencias emocionales de los enfermeros en la Salud Mental. Metodología: Estudio mixto que privilegia un estudio cuantitativo descriptivo y entrevistas semiestructuradas. Resultados: No existen diferencias estadísticas significativas entre los dos momentos. Teniendo en cuenta el análisis del contenido, los enfermeros identifican cambios positivos a nivel de su desarrollo personal y profesional, comunicación en equipo, gestión de conflictos y relaciones grupales. Refieren también alteraciones en la calidad de los cuidados ofrecidos y en la organización. Conclusiones: La implementación del Modelo SafeCare contribuyó para el desarrollo de las competencias emocionales en los enfermeros en el contexto de Salud Mental, sin embargo, serán necesarios más estudios que nos permitan además demostrar la eficacia de la implementación del modelo.
