Relationship Between the Quorum Network (Sensing/Quenching) and Clinical Features of Pneumonia and Bacteraemia Caused by A. baumannii
Acinetobacter baumannii (Ab) is one of the most important pathogens associated
with nosocomial infections, especially pneumonia. Interest in the Quorum network,
i.e., Quorum Sensing (QS)/Quorum Quenching (QQ), in this pathogen has grown
in recent years. The Quorum network plays an important role in regulating diverse
virulence factors such as surface motility and bacterial competition through the
type VI secretion system (T6SS), which is associated with bacterial invasiveness.
In the present study, we investigated 30 clinical strains of A. baumannii isolated in
the “II Spanish Study of A. baumannii GEIH-REIPI 2000-2010” (Genbank Umbrella
Bioproject PRJNA422585), a multicentre study describing the relationship between the
Quorum network in A. baumannii and the development of pneumonia and associated
bacteraemia. Expression of the aidA gene (encoding the AidA protein, QQ enzyme) was
lower (P < 0.001) in strains of A. baumannii isolated from patients with bacteraemic
pneumonia than in strains isolated from patients with non-bacteraemic pneumonia.
Moreover, aidA expression in the first type of strain was not regulated in the presence
of environmental stress factors such as the 3-oxo-C12-HSL molecule (substrate of AidA
protein, QQ activation) or H2O2 (inhibitor of AidA protein, QS activation). However, in the
A. baumannii strains isolated from patients with non-bacteraemic pneumonia, aidA gene
expression was regulated by stressors such as 3-oxo-C12-HSL and H2O2. In an in vivo
Galleria mellonella model of A. baumannii infection, the A. baumannii ATCC 17978 strain
was associated with higher mortality (100% at 24 h) than the mutant, abaI-deficient, strain (carrying a synthetase enzyme of Acyl homoserine lactone molecules) (70% at 24 h).
These data suggest that the QS (abaR and abaI genes)/QQ (aidA gene) network affects
the development of secondary bacteraemia in pneumonia patients and also the virulence
of A. baumannii.National Plan for Scientific ResearchTechnological Development and Innovation PI16/01163ISCIII-Deputy General Directorate for Evaluation and Promotion of Research-European Regional Development Fund A way of Making EuropeInstituto de Salud Carlos IIIMiguel Servet Research Programme SERGAS and ISCIIIXunta de Galicia (GAIN, Axencia de Innovación
La Imagen y la Narrativa como Herramientas para el Abordaje Psicosocial en Escenarios de Violencia. Departamentos de Boyacá y Caldas
Para esta última fase del proceso formativo, se tuvo en cuenta cada uno de los recursos teóricos y audiovisuales sugeridos en el entorno de conocimiento. De igual forma y con la intención de lograr mejores resultados que ayuden a fortalecer las bases conceptuales y prácticas ya adquiridas, se indagaron fuentes adicionales permitiendo así, un abordaje y óptica más integral. Las víctimas del conflicto armado han vivido momentos difíciles y en ocasiones, esto ha conducido a situaciones de crisis a corto, mediano y largo plazo. Sin embargo, dichos sucesos han permitido en las víctimas, oportunidades para reconocer sus valores, capacidades, habilidades y recursos, dando paso a un adecuado proceso de adaptación social.
En este documento encontrarán diferentes ejercicios académicos derivados del diplomado de profundización en acompañamiento psicosocial en escenarios de violencia, aspectos relacionados con historias de vida de víctimas del conflicto armado, lo que permite una reflexión académica en torno a las acciones psicosociales vinculando aspectos como la subjetividad y la interacción de actores. De igual modo, hace parte de este proceso la imagen y la narrativa; la herramienta de foto voz; el diseño y estructura de preguntas; el reconocimiento de impactos psicosociales y la formulación de estrategias para el abordaje psicosocial en escenarios de violencia.For the training process last phase, each one of the theoretical and audiovisual resources suggested in the knowledge environment were considered. Similarly, and with the intention of achieving better results which help to strength the conceptual and practical bases already acquired, additional sources were researched, allowing a more comprehensive approach and perspective.
The victims of the armed conflict have lived through difficult times and, at times, this has led to crisis situations in the short, medium and long term. However, these events have allowed to the victims the opportunities to recognize their values, capacities, abilities and resources, giving way to an adequate process of social adaptation.
In this paper you will find different academic exercises derived from the diploma deepening course in psychosocial accompaniment in violence scenarios, aspects related to victims life stories of armed conflict, which allows an academic reflection around the psychosocial actions linking aspects such as subjectivity and the actors interaction. In the same way, image and narrative are part of this process; the photo voice tool; the design and structure of questions; the recognition of psychosocial impacts and the formulation of strategies for the psychosocial approach in violence scenarios

Research of effectiveness and approval criteria for treatments with medications for patients with cancer: a review
Several malignant disorders of human tissues affect a large proportion of people in Colombia and worldwide, which has led to an increase in pharmacological treatments for these diseases, without the real benefit being clear to the patients who receive them. Furthermore, there are doubts about the quality of the evidence on which the institutions that support anticancer treatments with medications are based, such as the Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Our objective was to know how efficacy studies are carried out and how treatments with medications offered to people with cancer are approved. A narrative review was carried out, which was based on the formulation of questions that guided the development of the topics that were included. The search strategy was done in PubMed in a structured but non-systematic way. Articles published in english and spanish were included, without
restriction by publication date
Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)
Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters.
Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs).
Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001).
Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

XVI International Congress of Control Electronics and Telecommunications: "Techno-scientific considerations for a post-pandemic world intensive in knowledge, innovation and sustainable local development"
Este título, sugestivo por los impactos durante la situación de la Covid 19 en el mundo, y que en Colombia lastimosamente han sido muy críticos, permiten asumir la obligada superación de tensiones sociales, políticas, y económicas; pero sobre todo científicas y tecnológicas.
Inicialmente, esto supone la existencia de una capacidad de la sociedad colombiana por recuperar su estado inicial después de que haya cesado la perturbación a la que fue sometida por la catastrófica pandemia, y superar ese anterior estado de cosas ya que se encontraban -y aún se encuentran- muchos problemas locales mal resueltos, medianamente resueltos, y muchos sin resolver: es decir, habrá que rediseñar y fortalecer una probada resiliencia social existente - producto del prolongado conflicto social colombiano superado parcialmente por un proceso de paz exitoso - desde la tecnociencia local; como lo indicaba Markus Brunnermeier - economista alemán y catedrático de economía de la Universidad de Princeton- en su libro The Resilient Society…La cuestión no es preveerlo todo sino poder reaccionar…aprender a recuperarse rápido.This title, suggestive of the impacts during the Covid 19 situation in the world, and which have unfortunately been very critical in Colombia, allows us to assume the obligatory overcoming of social, political, and economic tensions; but above all scientific and technological.
Initially, this supposes the existence of a capacity of Colombian society to recover its initial state after the disturbance to which it was subjected by the catastrophic pandemic has ceased, and to overcome that previous state of affairs since it was found -and still is find - many local problems poorly resolved, moderately resolved, and many unresolved: that is, an existing social resilience test will have to be redesigned and strengthened - product of the prolonged Colombian social conflict partially overcome by a successful peace process - from local technoscience; As Markus Brunnermeier - German economist and professor of economics at Princeton University - indicates in his book The Resilient Society...The question is not to foresee everything but to be able to react...learn to recover quickly.Bogot

narrativos a partir de los relatos de vida de personas que sufrieron traumas por culpa de la
violencia, a partir de la construcción colaborativa se realizarán preguntas, estratégicas, circulares
y reflexivas con su respectiva justificación, donde se resolverán y se generará un debate
participativo y argumentativo que aporte desde las teorías.
También se analizará el caso Pandurí, donde su temática hace referencia a los procesos de
violencia que son sometidas algunas poblaciones de nuestro país, planteando varias estrategias
de abordaje psicosocial que faciliten la potenciación de recursos de afrontamiento a la situación
expresada en dicho caso.The present work has as purpose to carry out a conceptual approach to the approaches
narratives from the life stories of people who suffered traumas because of the
violence, from the collaborative construction will be asked questions, strategic, circular
and reflective with their respective justification, where they will be resolved and a debate will be generated
participatory and argumentative that contributes from theories.
The Pandurí case will also be analyzed, where its subject matter refers to the processes of
violence that some populations of our country are subjected to, proposing several strategies
of psychosocial approach that facilitate the empowerment of coping resources to the situation
expressed in that case
