[Adjuvant treatments to invasive mechanical ventilation in the management of acute respiratory distress syndrome secondary to COVID-19]. / Tratamientos coadyuvantes a la ventilación mecánica invasiva en el manejo del síndrome de distrés respiratorio agudo secundario a covid-19.

Introduction: This bibliographic review is carried out in order to obtain answers about aspects related to techniques and treatments, as well as care associated with the critically ill patient diagnosed with COVID-19. Objective: To analyze the available scientific evidence on the effectiveness of the use of invasive mechanical ventilation together with other adjuvant techniques, in reducing the mortality rate in patients with acute respiratory distress syndrome and clinical trial of COVID-19 treated in intensive care units. Methodology: A systematized bibliographic review was carried out in the PubMed, CUIDEN, LILACS, Medline, CINAHL and Google Scholar databases, using MeSH terms (adult respiratory distress syndrome, mechanical ventilation, prone position, nitric oxide, extracorporeal membrane oxygenation, nursing care) and the corresponding Boolean operators. The selected studies underwent a critical reading carried out between December 6, 2020 and March 27, 2021 using the Critical Appraisal Skills Program tool in Spanish and a cross-sectional epidemiological studies evaluation instrument. Results: A total of 85 articles were selected. After performing the critical reading, a total of 7 articles were included in the review, 6 being descriptive studies and one a cohort study. After analyzing these studies, it appears that the technique that has obtained the best results is extracorporeal membrane oxygenation, with the care provided by qualified and trained nursing staff being very important. Conclusion: Mortality from COVID-19 increases in patients treated with invasive mechanical ventilation compared to patients treated with extracorporeal membrane oxygenation. Nursing care and specialization can have an impact on improving patient outcomes.

Curcumin ameliorates autoimmune diabetes. Evidence in accelerated murine models of type 1 diabetes.

Type 1 diabetes (T1DM) is a T cell-mediated autoimmune disease that selectively destroys pancreatic ß cells. The only possible cure for T1DM is to control autoimmunity against ß cell-specific antigens. We explored whether the natural compound curcumin, with anti-oxidant and anti-inflammatory activities, might down-regulate the T cell response that destroys pancreatic ß cells to improve disease outcome in autoimmune diabetes. We employed two accelerated autoimmune diabetes models: (i) cyclophosphamide (CYP) administration to non-obese diabetic (NOD) mice and (ii) adoptive transfer of diabetogenic splenocytes into NODscid mice. Curcumin treatment led to significant delay of disease onset, and in some instances prevented autoimmune diabetes by inhibiting pancreatic leucocyte infiltration and preserving insulin-expressing cells. To investigate the mechanisms of protection we studied the effect of curcumin on key immune cell populations involved in the pathogenesis of the disease. Curcumin modulates the T lymphocyte response impairing proliferation and interferon (IFN)-γ production through modulation of T-box expressed in T cells (T-bet), a key transcription factor for proinflammatory T helper type 1 (Th1) lymphocyte differentiation, both at the transcriptional and translational levels. Also, curcumin reduces nuclear factor (NF)-κB activation in T cell receptor (TCR)-stimulated NOD lymphocytes. In addition, curcumin impairs the T cell stimulatory function of dendritic cells with reduced secretion of proinflammatory cytokines and nitric oxide (NO) and low surface expression of co-stimulatory molecules, leading to an overall diminished antigen-presenting cell activity. These in-vitro effects correlated with ex-vivo analysis of cells obtained from curcumin-treated mice during the course of autoimmune diabetes. These findings reveal an effective therapeutic effect of curcumin in autoimmune diabetes by its actions on key immune cells responsible for ß cell death.

Adjuvant treatments to invasive mechanical ventilation in the management of acute respiratory distress syndrome secondary to COVID-19.

INTRODUCTION: This bibliographic review is carried out in order to obtain answers about aspects related to techniques and treatments, as well as care associated with the critically ill patient diagnosed with Covid-19. OBJECTIVE: To analyze the available scientific evidence on the effectiveness of the use of invasive mechanical ventilation together with other adjuvant techniques, in reducing the mortality rate in patients with Acute Respiratory Distress Syndrome and clinical trial of Covid-19 treated in intensive care units. METHODOLOGY: A systematized bibliographic review was carried out in the Pubmed, Cuiden, Lilacs, Medline, Cinahl and Google Scholar databases, using MeSH terms (Adult Respiratory Distress Syndrome, Mechanical Ventilation, Prone Position, Nitric Oxide, Extracorporeal Membrane Oxygenation, Nursing Care) and the corresponding Boolean operators. The selected studies underwent a critical reading carried out between December 6, 2020 and March 27, 2021 using the Critical Appraisal Skills Program tool in Spanish and a cross-sectional epidemiological studies evaluation instrument. RESULTS: A total of 85 articles were selected. After performing the critical reading, a total of 7 articles were included in the review, 6 being descriptive studies and 1 cohort study. After analyzing these studies, it appears that the technique that has obtained the best results is ECMO, with the care provided by qualified and trained nursing staff being very important. CONCLUSION: Mortality from Covid-19 increases in patients treated with invasive mechanical ventilation compared to patients treated with extracorporeal membrane oxygenation. Nursing care and specialization can have an impact on improving patient outcomes.

[Knowledge and attitudes of health care professionals in advance healthcare directives]. / Conocimientos y actitudes sobre voluntades anticipadas en profesionales sanitarios.

BACKGROUND AND OBJECTIVE: The advanced healthcare directive is a new style of health care relationship, based on the respect of the patients autonomous decisions: as well as a valuable tool that enables a proper management of the decisions made at the end of life. The objective of this study was to explore the knowledge and attitudes of the health care professionals regarding the advance directives, as well as the resources for advanced care planning in a municipality of Madrid during 2016-2017. MATERIAL AND METHODS: A cross-sectional descriptive study was carried out on a population of Health care professionals of Primary and Specialised Care. The knowledge and attitudes questionnaire about the advance directives was used. Sociodemographic and knowledge variables related to resources for the advanced care planning. Statistical-descriptive analysis was performed. RESULTS: A total of 431 professionals were included, with a mean age of 44.55 years (SD: 11.1). As regards knowledge about advance directives, the mean score was 5.08 (SD 2.4), with statistically significant differences being found between professional groups. A small percentage (4.6%) of the professionals had their document of Advance directives ready, and 42% of professionals did not know if they were regulated by the Community of Madrid. Less than half (41.5%) of the professionals knew the palliative resources of their institution. CONCLUSIONS: The health care professional's knowledge about advance directives, as well as the resources for the advanced care planning, show deficiencies at training and information level. Almost half of the professionals did not know if these are regulated in the Community of Madrid. They also believe that it would be useful to plan, and very useful to have the Advance directives document ready.
