RT-PCR multiplex para la detección simultánea de las mutaciones FLT3-ITD/NPM-1/AML1-ETO asociadas a Leucemia Mieloide Aguda
La Leucemia Mieloide Aguda (LMA) representa un grupo de neoplasias muy heterogéneo. Las aberraciones citogenéticas detectadas en el momento del diagnóstico son el marcador pronóstico más comúnmente utilizado. Sin embargo, el 20% de los casos de LMA presentan un cariotipo normal. Dentro de este grupo de pacientes la presencia de mutaciones del tipo FLT3-ITD se considera de mal pronóstico. Sin embargo, la presencia de la mutación NMP1 o AML1-ETO se asocia a un mejor pronóstico. En este contexto, el objetivo de este trabajo es el desarrollo de una técnica de diagnóstico molecular hematológico, que permita la detección simultánea de mutaciones para estos tres genes. Hemos desarrollado un método basado en la reacción en cadena de la polimerasa (PCR) que permite amplificar y visualizar simultáneamente estos 3 marcadores tanto desde ARN (un paso) como desde ADNc (dos pasos). De las 28 muestras analizadas, 6 (21,42 %) muestras fueron positivas para FLT3-ITD, 7 para NPM-1 (25%) y otras 4 (14,28) para AML1-ETO. Al comparar ambos métodos (ADNc vs ARN) con métodos convencionales los resultados de las 28 muestras estudiadas fue equivalente en el 100% de los casos, demostrando la robustez de los mismos.Acute Myeloid Leukemia (AML) is a heterogeneous group of neoplasms. The cytogenetic aberrations detected at the time of diagnosis are most commonly used as prognostic marker. However, 20% of AML patients exhibit a normal karyotype. Within this group of patients the presence of FLT3 -ITD mutations type is considered of poor prognosis. However, the presence of AML1 –ETO or NMP-1 or mutation is associated with a better prognosis. In this context, the aim of this work is to develop a technique of molecular diagnostic in hematology, allowing the simultaneous detection of mutations for these three genes. We have developed a method based on PCR that simultaneously amplifies and visualizes these three molecular markers both from RNA (one- step) and from cDNA (step two). Of the 28 samples tested, 6 (21.42%) samples were positive for FLT3 -ITD, 7 for NPM- 1 (25% ) and 4 ( 14,28 ) for AML1 -ETO . When comparing the two methods (cDNA vs RNA) by conventional techniques the obtained results from the 28 samples tested was equivalent in 100% of cases, demonstrating the robustness of this development

Effect of the aniline fragment in Pt(II) and Pt(IV) complexes as anti-proliferative agents. Standard reduction potential as a more reliable parameter for Pt(IV) compounds than peak reduction potential
The problems of resistance and side effects associated with cisplatin and other chemotherapeutic drugs have boosted research aimed at finding new compounds with improved properties. The use of platinum(IV) prodrugs is one alternative, although there is some controversy regarding the predictive ability of the peak reduction potentials. In the work described here a series of fourteen chloride Pt(II) and Pt(IV) compounds was synthesised and fully characterised. The compounds contain different bidentate arylazole heterocyclic ligands. Their cytotoxic properties against human lung carcinoma (A549), human breast carcinoma (MCF7) and human colon carcinoma (HCT116 and HT29) cell lines were studied. A clear relationship between the type of ligand and the anti-proliferative properties was found, with the best results obtained for the Pt(II) compound that contains an aniline fragment, (13), thus evidencing a positive effect of the NH2 group. Stability and aquation studies in DMSO, DMF and DMSO/water mixtures were carried out on the active complexes and an in-depth analysis of the two aquation processes, including DFT analysis, of 13 was undertaken. It was verified that DNA was the target and that cell death occurred by apoptosis in the case of 13. Furthermore, the cytotoxic derivatives did not exhibit haemolytic activity. The reduction of the Pt(IV) compounds whose Pt(II) congeners were active was studied by several techniques. It was concluded that the peak reduction potential was not useful to predict the ability for reduction. However, a correlation between the cytotoxic activity and the standard reduction potential was found.This work has been funded by the Spanish Ministerio de Ciencia, Innovación y Universidades (MCIU), Agencia Estatal de Investigación (AEI) and Fondo Europeo de Desarrollo Regional (FEDER) (RTI2018-100709-B-C21 to BRM, RTI2018-100709-B-C22 to AM, RTI2018-094093-B-I00 to RSP), Junta de Comunidades de Castilla-La Mancha-FEDER (JCCM) (grant SBPLY/19/180501/000260 to BRM), Ministerio de Economía y Competitividad (Project PID2019-104381GB-I00 to GC), Fundación Leticia Castillejo Castillo to MJRH, Junta de Castilla y León, Consejería de Educación y Cultura y Fondo Social Europeo (Projects BU263P18 and BU087G19 to JVC) as well as UCLM-FEDER (grants 2019-GRIN-27183 and 2019-GRIN-27209 to BRM) and University of Girona (MPCUdG2016/076 to AM)

COVID-19 outbreaks in a transmission control scenario: challenges posed by social and leisure activities, and for workers in vulnerable conditions, Spain, early summer 2020
Severe acute respiratory syndrome coronavirus 2 community-wide transmission declined in Spain by early May 2020, being replaced by outbreaks and sporadic cases. From mid-June to 2 August, excluding single household outbreaks, 673 outbreaks were notified nationally, 551 active (>6,200 cases) at the time. More than half of these outbreaks and cases coincided with: (i) social (family/friends’ gatherings or leisure venues) and (ii) occupational (mainly involving workers in vulnerable conditions) settings. Control measures were accordingly applied

Predictive Power of the "Trigger Tool" for the detection of adverse events in general surgery: a multicenter observational validation study
Background
In spite of the global implementation of standardized surgical safety checklists and evidence-based practices, general surgery remains associated with a high residual risk of preventable perioperative complications and adverse events. This study was designed to validate the hypothesis that a new “Trigger Tool” represents a sensitive predictor of adverse events in general surgery.
Methods
An observational multicenter validation study was performed among 31 hospitals in Spain. The previously described “Trigger Tool” based on 40 specific triggers was applied to validate the predictive power of predicting adverse events in the perioperative care of surgical patients. A prediction model was used by means of a binary logistic regression analysis.
Results
The prevalence of adverse events among a total of 1,132 surgical cases included in this study was 31.53%. The “Trigger Tool” had a sensitivity and specificity of 86.27% and 79.55% respectively for predicting these adverse events. A total of 12 selected triggers of overall 40 triggers were identified for optimizing the predictive power of the “Trigger Tool”.
Conclusions
The “Trigger Tool” has a high predictive capacity for predicting adverse events in surgical procedures. We recommend a revision of the original 40 triggers to 12 selected triggers to optimize the predictive power of this tool, which will have to be validated in future studies
