Abstract
DNA in living beings is constantly damaged by exogenous and endogenous agents. However, in some cases, DNA photodamage can have interesting applications, as it happens in photodynamic therapy. In this work, the current knowledge on the photophysics of 4-thiouracil has been extended by further quantum-chemistry studies to improve the agreement between theory and experiments, to better understand the differences with 2-thiouracil, and, last but not least, to verify its usefulness as a photosensitizer for photodynamic therapy. This study has been carried out by determining the most favorable deactivation paths of UV-vis photoexcited 4-thiouracil by means of the photochemical reaction path approach and an efficient combination of the complete-active-space second-order perturbation theory//complete-active-space self-consistent field (CASPT2//CASSCF), (CASPT2//CASPT2), time-dependent density functional theory (TDDFT), and spin-flip TDDFT (SF-TDDFT) methodologies. By comparing the data computed herein for both 4-thiouracil and 2-thiouracil, a rationale is provided on the relatively higher yields of intersystem crossing, triplet lifetime and singlet oxygen production of 4-thiouracil, and the relatively higher yield of phosphorescence of 2-thiouracil.

Abstract
The study of peripheral blood mononuclear cells (PBMCs) in immune-mediated diseases, such as celiac disease (CD), is important to uncover pathogenesis, find new biomarkers and discover and evaluate new treatments. Many studies have been published about the use and value of PBMCs in CD such as those including enzyme-linked immunospot (ELISPOT) assays, flow cytometry, peptide-MHC tetramers, genetic and proteomic analyses, and in vitro and proliferation assays. We present here and easy and efficient method for isolation of PBMCs using density gradient centrifugation. We also describe a simple way to freeze PBMCs in order to preserve their number and viability and a thawing procedure leading to high rates of viability of the cryopreserved cells to be used in subsequent applications.

Abstract
The Clinical and Translational Science Award (CTSA) Program recognizes that advancing diversity, equity, inclusion, and accessibility (DEIA) requires moving beyond statements of commitment to transformative actions. In 2021, the CTSA Program created a Task Force (TF) to initiate work in support of structural and transformational initiatives that advance DEIA for the consortium and its individual hubs. We describe the process of forming the expertise-driven (DEIA) TF and our activities to date. We 1) developed and adopted the DEIA Learning Systems Framework to guide our approach; 2) defined a set of recommendations across four focus areas (Institutional; Programmatic; Community-Centered; and Social, Cultural, Environmental); and 3) designed and disseminated a survey to capture the CTSA Program's baseline demographic, community, infrastructural, and leadership diversity. The CTSA Consortium also elevated the TF to a standing Committee to extend our understanding, development, and implementation of DEIA approaches to translational and clinical science. These initial steps provide a foundation for collectively fostering environment that support DEIA across the research continuum.

Abstract
Accurate celiac disease (CD) diagnosis must be performed in individuals following a gluten containing diet. Diagnostic procedures for individuals already on a gluten-free diet (GFD) avoiding long gluten reintroductions are still challenging. To deal with this issue, we developed an accurate but simple method that requires only a 3-day gluten challenge and circumvents the main limitations of previously suggested proposals such as requirement of specific peptides and unusual specialized lab facilities or high cost. In an attempt to standardize this methodology to be used in daily clinical practice, we describe here an optimized protocol for assessing activated gut-homing CD8+ T cells in blood combined with a short gluten challenge. Details about the amount and type of gluten antigen and the starting material are included, as well as the strategy to easily characterize and identify the cells of interest using flow cytometry. This methodology constitutes a diagnostic tool for CD diagnosis of high specificity and sensitivity for seropositive disease (>95%) as an alternative to long-term gluten challenge and open new possibilities to test the response to gluten in research and clinical trials.

Abstract
In addition to restrictions on conducting research, COVID-19-related travel bans and scientific meeting cancellations have negatively affected scholars in the Clinical and Translational Science Award (CTSA) Mentored Career Development Award (KL2) program. In response, a national virtual visiting scholar program was developed to provide opportunity for KL2 scholars to be virtual visiting professors at another CTSA hub, meet faculty and scholars, and expand networks and build collaborations. This article describes the design and short-term outcomes of the virtual CTSA Visiting Scholar Program. In 2020, a working group designed core program elements and developed an application and selection process. Anonymized surveys were sent to scholars post visit and to scholars and program directors 6 months post visit to evaluate their experience and solicit suggestions for improvements. Between November 2020 and May 2021, 56 KL2 scholars and 27 hubs participated. Forty-five (80.4%) participating scholars responded to the initial survey. Nearly all scholars (44, 97.7%) agreed their experience was valuable. All respondents indicated they would recommend the program to other KL2 scholars. For the 6-month survey, the response rate was 87.5% (49/56). Within 6 months of their visit, 36 (73.5%) respondents had contacted at least one person at the host hub and for 17 (34.7%) respondents, new collaborations with the host hub ensued. Twenty-five of 27 (92.6%) host hubs responded to the survey. Most (21, 84.0%) agreed that hearing visiting scholar talks was valuable to their own scholars and 23 (92%) indicated likelihood of their hub participating in future round of the program. The virtual Visiting Scholar Program provided KL2 scholars an opportunity to virtually visit another CTSA hub, present their research, and meet with faculty and other scholars to expand their networks. Although geared to KL2 scholars, this model is potentially generalizable to other nationally coordinated career development programs.

Abstract
BACKGROUND The diagnosis of coeliac disease (CD) in individuals that have started a gluten-free diet (GFD) without an adequate previous diagnostic work-out is a challenge. Several immunological assays such as IFN-γ ELISPOT have been developed to avoid the need of prolonged gluten challenge to induce the intestinal damage. We aimed to evaluate the diagnostic accuracy of activated gut-homing CD8+ and TCRγδ+ T cells in blood after a 3-day gluten challenge and to compare it with the performance of IFN-γ ELISPOT in a HLA-DQ2.5 subsample. METHODS A total of 22 CD patients and 48 non-CD subjects, all of them following a GFD, underwent a 3-day 10-g gluten challenge. The percentage of two T cell subsets (CD8+ CD103+ β7hi CD38+/total CD8+ and TCRγδ+ CD103+ β7hi CD38+/total TCRγδ+) in fresh peripheral blood drawn baseline and 6 days after the challenge was determined by flow cytometry. IFN-γ ELISPOT assays were also performed in HLA-DQ2.5 participants. ROC curve analysis was used to assess the diagnostic performance of the CD8+ T cell response and IFN-γ ELISPOT. RESULTS Significant differences between the percentage of the two studied subsets of CD8+ and TCRγδ+ cells at days 0 and 6 were found only when considering CD patients (p < 10-3 vs. non-CD subjects). Measuring activated CD8+ T cells provided accurate CD diagnosis with 95% specificity and 97% sensitivity, offering similar results than IFN-γ ELISPOT. CONCLUSIONS The results provide a highly accurate blood test for CD diagnosis in patients on a GFD of easy implementation in daily clinical practice.

Abstract
Aquaculture is a potential source of microplastics (MPs) that could be strong stressors for marine organisms. In this study, we evaluated the effects of MPs derived from aquaculture in antioxidant defences and oxidative stress markers in gills of Mytilus galloprovincialis. Mussels were distributed in three areas with different impacts: inside aquaculture cages, Control 1 (located inside Andratx harbour) and Control 2 (located in a no-anthropized area). Samples were obtained along three different time periods in May (T0), July (T60) and in September (T120). At each sampling period, mussels' biometric measurements were taken, and tissue samples were kept frozen for biochemical determinations and to determine the intake of MPs. An increase in MPs intake was detected throughout the study, and this increase was significantly higher in samples from the aquaculture cages. Similarly, antioxidant enzyme activities (catalase, superoxide dismutase, glutathione reductase and glutathione peroxidase) were significantly higher in samples from cages at T120. Additionally, a similar tendency was observed in glutathione-s-transferase, with a higher activity in the aquaculture cages at T60 and T120. Malondialdehyde and carbonyl protein derivates as a marker of oxidative damage were also measured and samples from aquaculture cages presented higher oxidative stress markers, mainly in T120. In conclusion, living in environments exposed to aquaculture activities at sea may imply a higher intake of MPs which in turn might cause an antioxidant response in M. galloprovincialis which is not enough to avoid oxidative damage.

Abstract
Severe malaria (SM) is a major public health problem in malaria-endemic countries. Sequestration of Plasmodium falciparum–infected erythrocytes in vital organs and the associated inflammation leads to organ dysfunction. MicroRNAs (miRNAs), which are rapidly released from damaged tissues into the host fluids, constitute a promising biomarker for the prognosis of SM. We applied next-generation sequencing to evaluate the differential expression of miRNAs in SM and in uncomplicated malaria (UM. Six miRNAs were associated with in vitro P. falciparum cytoadhesion, severity in children, and P. falciparum biomass. Relative expression of hsa-miR-4497 quantified by TaqMan-quantitative reverse transcription PCR was higher in plasma of children with SM than those with UM (p<0.048) and again correlated with P. falciparum biomass (p = 0.033). These findings suggest that different physiopathological processes in SM and UM lead to differential expression of miRNAs and pave the way for future studies to assess their prognostic value in malaria.

Abstract
Luminol is a popular molecule that is currently gaining further interest due to its potential role for non-invasive cancer treatments. Design of more efficient derivatives in this context would benefit from a clear knowledge on the origin of the distinct intensity and spectroscopic properties in protic and aprotic solvents observed experimentally, which are still not rationalized. By efficiently combining molecular dynamics, quantum methodologies based on density functional theory and multiconfigurational quantum chemistry and hybrid approaches, and developing herein a computational approach for accurately determining "molar negative extinction (or gain) coefficients of emission", we firstly demonstrate that the amino and imino forms of the 3-aminophthalate dianion are responsible for the chemiluminescence in protic and aprotic medium, respectively. Secondly, we show that the coupling between the adjacent amino and carboxylate groups of luminol existing in aprotic solvents must be kept in aqueous solution to increase the chemiexcitation and emission intensity. Thirdly, modifications of luminol are proposed and simulated showing improved performances as compared to the parent molecule (stronger emission electronic transition and longer emission wavelengths) under the physiological conditions of relevance in biological and medical applications.

Abstract
Neutrophils are detected in inflamed colon in Crohn's disease (CD). However, whether the frequency and/or activation of circulating or gut tissue neutrophils correlate with endoscopic severity remains to be investigated. A cohort of 73 CD patients was prospectively enrolled according to endoscopic severity and treatment history. Individuals with active disease were stratified using the Montreal classification. Harvey-Bradshaw Index (HBI) and Simple Endoscopic Score for Crohn's Disease (SES-CD) were performed at the time of ileocolonoscopy. Frequency of neutrophils and their expression of CD66b and CD64 were assessed in paired blood and colonic biopsies using flow cytometry. The percentage of neutrophils increased in inflamed colon and correlated with SES-CD in the entire cohort of patients examined, as well as in the subgroup with inflammatory (B1) active disease. SES-CD further correlated with neutrophil CD66b expression in mucosa but not blood and, conversely, with neutrophil CD64 expression in blood but not mucosa. However, the evaluation of neutrophil activation in mucosa when compared to blood reflected disease activity more clearly. Finally, a neutrophil activation power index (CD66b in mucosa X CD64 in blood) that correlated with SES-CD discriminated between patients with mild and severe disease. In conclusion, the frequency and activation of colonic neutrophils correlated with SES-CD, highlighting that mucosal neutrophils are associated with disease severity in CD.

Abstract
<p>La ciudad de Córdoba inauguró el 22 de abril de 1997 el Obsevatorio Ambiental Municipal. Hasta el año 2001 la ciudad contó con una red automática de monitoreo de contaminación atmosférica que generaba mediciones continuas de contaminantes criterio (NO2, SO2, CO, O3 y PM10). Otros contaminantes atmosféricos no convencionales como los Compuestos Orgánicos Volátiles (COV´s), también fueron medidos pero en campañas esporádicas y poco consistentes. Este trabajo parte de la necesidad de disponer de mediciones de concentración ambiente de COV´s para la evaluación de riesgo en salud y para la toma de decisiones en políticas públicas y privadas, ya que las mismas requieren información sobre los niveles de exposición de la población al contaminante, el número de personas expuestas, el tiempo de exposición<br />y el conocimiento de las relaciones cuantitativas entre exposición y efectos en la salud. En esta comunicación breve informamos sobre los resultados de un año de monitoreo continuo de COV´s realizado en el microcentro de la ciudad de Córdoba.</p>

Abstract
Circulating small RNAs, including miRNAs but also isomiRs and other RNA species, have the potential to be used as non-invasive biomarkers for communicable and non-communicable diseases. This study aims to characterize and compare small RNA profiles in human biofluids. For this purpose, RNA was extracted from plasma and breast milk samples from 15 healthy postpartum mothers. Small RNA libraries were prepared with the NEBNext® small RNA library preparation kit and sequenced in an Illumina HiSeq2000 platform. miRNAs, isomiRs and clusters of small RNAs were annotated using seqBuster/seqCluster framework in 5 plasma and 10 milk samples that passed the initial quality control. The RNA yield was 81 ng/mL [standard deviation (SD): 41] and 3985 ng/mL (SD: 3767) for plasma and breast milk, respectively. Mean number of good quality reads was 4.04 million (M) (40.01% of the reads) in plasma and 12.5M (89.6%) in breast milk. One thousand one hundred eighty two miRNAs, 12,084 isomiRs and 1,053 small RNA clusters that included piwi-interfering RNAs (piRNAs), tRNAs, small nucleolar RNAs (snoRNA) and small nuclear RNAs (snRNAs) were detected. Samples grouped by biofluid, with 308 miRNAs, 1,790 isomiRs and 778 small RNA clusters differentially detected. In summary, plasma and milk showed a different small RNA profile. In both, miRNAs, piRNAs, tRNAs, snRNAs, and snoRNAs were identified, confirming the presence of non-miRNA species in plasma, and describing them for the first time in milk.

Abstract
The gametocytes of Plasmodium falciparum, responsible for the transmission of this malaria parasite from humans to mosquitoes, accumulate and mature preferentially in the human bone marrow. In the 10 day long sexual development of P. falciparum, the immature gametocytes reach and localize in the extravascular compartment of this organ, in contact with several bone marrow stroma cell types, prior to traversing the endothelial lining and re-entering in circulation at maturity. To investigate the host parasite interplay underlying this still obscure process, we developed an in vitro tridimensional co-culture system in a Matrigel scaffold with P. falciparum gametocytes and self-assembling spheroids of human bone marrow mesenchymal cells (hBM-MSCs). Here we show that this co-culture system sustains the full maturation of the gametocytes and that the immature, but not the mature, gametocytes adhere to hBM-MSCs via trypsin-sensitive parasite ligands exposed on the erythrocyte surface. Analysis of a time course of gametocytogenesis in the co-culture system revealed that gametocyte maturation is accompanied by the parasite induced stimulation of hBM-MSCs to secrete a panel of 14 cytokines and growth factors, 13 of which have been described to play a role in angiogenesis. Functional in vitro assays on human bone marrow endothelial cells showed that supernatants from the gametocyte mesenchymal cell co-culture system enhance ability of endothelial cells to form vascular tubes. These results altogether suggest that the interplay between immature gametocytes and hBM-MSCs may induce functional and structural alterations in the endothelial lining of the human bone marrow hosting the P. falciparum transmission stages.

Abstract
Purpose To detect retinal pigment epithelium (RPE) tears in predominantly classic choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) treated with intravitreal bevacizumab injections. Methods Forty consecutive patients with predominantly classic CNV secondary to AMD were treated with 1.25 mg of intravitreal bevacizumab. Patients were evaluated with visual acuity (VA) measured with Early Treatment Diabetic Retinopathy Study charts, optical coherence tomography, and fluorescein angiography. Results Three patients developed a RPE tear after the first injection. The first patient had been treated with verteporfin therapy and VA remained unchanged. In the other two cases the CNV was naïve and VA improved since the foveal center was not involved by the tear and macular edema was reduced. Conclusions RPE tears can occur following intravitreal bevacizumab injections in patients with predominantly classic CNV although VA is not always affected.

Abstract
SummaryThis study aims to establish the relative effectiveness and safety of low molecular weight heparin in elderly patients with venous thrombosis in order to find an alternative to oral anticoagulant therapy with less bleeding complications in the long-term treatment of deep venous thrombosis (DVT).One hundred consecutive elderly patients (>75 years old) with venographically demonstrated proximal DVT were included in a randomized trial. All patients were treated for ten days with adjusted doses of intravenous heparin. Informed consent was obtained and on the eight day, patients were randomly allocated to receive acenocoumarol (INR 2.0-3.0) or subcutaneous enoxaparin (4000 anti-Xa units once a day) for three months. All patients were followed-up clinically and venographically for a one year period. The results were analyzed with Fisher’s exact test or chi-square test as appropriate.During the treatment and surveillance period, 6 of the 50 patients (12%) who received acenocoumarol and 8 of the 50 patients (16%) who received enoxaparin had new episodes of venous thromboembolism confirmed by objective testing (p = 0.6; 95% CI for the difference: −19.5 to 11.5). Hemorrhagic complications occurred in six of the 50 patients (12%) who received acenocoumarol and in one (2%) of those on enoxaparin (p = 0.1; 95% CI for the difference: -1.8 to 21.8). Vertebral fractures developed in 2 patients (4%) in the enoxaparin group (p = 0.5; 95% CI for the diference: −11.4 to 3.4).These results show that fixed dose enoxaparin seems to be effective and safe in the long-term treatment of proximal DVT in the elderly. In comparison with oral anticoagulants, the findings are inconclusive due to the wide confidence intervals for differences between outcomes, however they suggest that the former may have less bleeding complications with similar efficacy.

Abstract
OBJECTIVE This trial evaluates the impact of psychosocial and esthetic self-perceptions of patients undergoing nonvital tooth bleaching using the walking bleach technique. We also assessed the clinical effectiveness of bleaching tooth discoloration. METHODS Fifty volunteers with nonvital tooth discoloration were enrolled. Teeth were randomized into two groups: 35% hydrogen peroxide (n=25) and 37% carbamide peroxide (n=25). Intracoronal bleaching was performed over four sessions using the walking bleach technique. Tooth color was evaluated at each session to measure total color variation. The shade guide was arranged from highest (B1) to lowest (C4) values to assess the color and calculate the color change in the number of shade guide units. Subjective and objective assessments were compared with the tooth counterpart. Esthetic self-perception and psychosocial factors were assessed before and after treatment. RESULTS Color change was 15.48<5.17 for hydrogen peroxide and 14.02<4.85 for carbamide peroxide. There was no significant difference at any time point (p>0.05) except at sessions 3 and 4 (p<0.05). Overall, whitened teeth values were similar to those of counterpart teeth (p>0.05). There was a decrease in Oral Health Impact Profile and Psychosocial Impact of Dental Esthetics questionnaire scores after treatment compared with baseline (p<0.05). CONCLUSION The walking bleach technique was highly effective on nonvital teeth and had a positive effect on self-esthetic perception and psychological impact for the patients.

Abstract
The goal of this study was to develop an evaluation method of antiretroviral treatment adherence from a hospital pharmacy and to identify one or more factors that influenced this adherence, such as patient or treatment characteristics. The HIV patients included in this study were based, for the major part, in Saint-André hospital and collected their medication from this hospital pharmacy. They were all delivered a renewable prescription that should have comprised two successive delivery stamps. A total of 186 patients was included. For the adherence analysis, the delay between two successive deliveries was measured. We have specified three different categories of patients: adherent, non-adherent and intermediate, according to a definition of adherence accepted by many authors. We have demonstrated that the only antiretroviral therapeutic class associated with poor adherence was the protease inhibitors, in particular nelfinavir, which requires food to be taken at the time of administration. This can pose difficulties for those patients who lunch at their workplace and consequently affect adherence. This study allowed us to demonstrate that a less subjective adherence evaluation can be easily carried out from a hospital pharmacy.

Abstract
Severe burn patients are one subset of critically patients in which the burn injury increases the risk of infection, systemic inflammatory response and sepsis. The infections are usually related to devices and to the burn wound. Most infections, as in other critically ill patients, are preceded by colonization of the digestive tract and the preventative measures include selective digestive decontamination and hygienic measures. Early excision of deep burn wound and appropriate use of topical antimicrobials and dressings are considered of paramount importance in the treatment of burns. Severe burn patients usually have some level of systemic inflammation. The difficulty to differentiate inflammation from sepsis is relevant since therapy differs between patients with and those without sepsis. The delay in prescribing antimicrobials increases morbidity and mortality. Moreover, the widespread use of antibiotics for all such patients is likely to increase antibiotic resistance, and costs. Unfortunately the clinical usefulness of biomarkers for differential diagnosis between inflammation and sepsis has not been yet properly evaluated. Severe burn injury induces physiological response that significantly alters drug pharmacokinetics and pharmacodynamics. These alterations impact antimicrobials distribution and excretion. Nevertheless the current available literature shows that there is a paucity of information to support routine dose recommendations.

Abstract
Symptoms caused by bacterial, viral and malarial infections usually overlap and aetiologic diagnosis is difficult. Patient management in low-resource countries with limited laboratory services has been based predominantly on clinical evaluation and syndromic approaches. However, such clinical assessment has limited accuracy both for identifying the likely aetiological cause and for the early recognition of patients who will progress to serious or fatal disease. Plasma-detectable biomarkers that rapidly and accurately diagnose severe infectious diseases could reduce morbidity and decrease the unnecessary use of usually scarce therapeutic drugs. The discovery of microRNAs (miRNAs) has opened exciting new avenues to identify blood biomarkers of organ-specific injury. This review assesses current knowledge on the relationship between malaria disease and miRNAs, and evaluates how future research might lead to the use of these small molecules for identifying patients with severe malaria disease and facilitate treatment decisions.

Abstract
BACKGROUND AND OBJECTIVES The decriminalisation of euthanasia and assisted medical suicide has generated a continuous debate. The terminological confusion is one of the main difficulties in obtaining medical practice consensus. The objective of this study was to determine whether the terms of Euthanasia and physician assisted suicide are used with the same meaning by doctors in Extremadura (Spain). MATERIAL AND METHOD A qualitative study was conducted using two focus groups in which doctors from different specialties who attended a large number of terminal patients participated. No other focus group was required due to saturation. The sessions were tape recorded and transcribed by two experts in qualitative methodology. Atlas.ti software was used for the analysis. We were advised by the "Health Care at the end of life" Group of the Organizacion Médica Colegial of Spain. RESULTS Terminological confusion was verified in: 1) The mixture of etymological, functional and social concepts, 2) the term Passive Euthanasia, 3) the association between euthanasia and physician assisted suicide, 4) the confusion with the equivalent "wish to hasten death", and 5) the difficulty of differentiating sedation with Euthanasia. There was consensus on some aspects: a) Full voluntariness, b) the condition of terminal illness, and c) the condition of unbearable symptoms. CONCLUSIONS Conceptual variability persists in relation to the concept of Euthanasia, and is particularly noticeable in the persistence of the concept of passive euthanasia. It would be desirable to achieve a common language to assign a precise meaning to these words to help doctors in their professional practice.

Abstract
In the central nervous system, tissue-type plasminogen activator (tPA) has been associated with both pro-death and prosurvival actions on neurons. In most cases, this has been related to exogenous tPA. In the present study, we addressed the influence of endogenous tPA. We first observed an increased transcription of tPA following either in vivo global brain ischemia in rats or in vitro oxygen glucose deprivation (OGD) on mice and rats hippocampal slices. Hippocampal slices from tPA-deficient mice were more sensitive to OGD than wild-type slices. Pharmacological approaches targeting the known receptors of tPA revealed that only the inhibition of phosphorylation of epidermal growth factor receptors (EGFRs) prevented the neuroprotective effect of endogenous tPA. This study shows that ischemic hippocampal neurons overproduce endogenous tPA as an intend to protect themselves from ischemic death, by a mechanism involving an activation of EGFRs. Thus, strategies contributing to promote either endogenous production of tPA or its associated EGFR-linked signaling pathway may have beneficial effects following brain injuries such as stroke.

Abstract
OBJECTIVES To estimate the incremental cost per life-year gained (LYG) of aflibercept in combination with FOLFIRI as second-line treatment in metastatic colorectal cancer (mCRC) patients previously treated with oxaliplatin. METHODS Based on clinical trial VELOUR results, a three-state Markov model (stable disease, progression and death) with 2-week cycle duration was designed. Transition to health state «progression» implied the interruption of second-line treatment and administration of a third-line treatment (post-second line chemotherapy). Cost estimation included disease management cost (pharmaceutical, adverse event management, administration costs, etc.). Both cost and outcomes were discounted (3% annually). Sensitivity analyses (SA) were performed to test model robustness. RESULTS Administration of aflibercept + FOLFIRI as second-line treatment provided 1.78 LYG (21 life-months gained). With FOLFIRI 1.43 LYG (17 months) were obtained. The cost of the clinical management of aflibercept + FOLFIRI implied an additional investment of Euros 13,564 compared with FOLFIRI for a lifetime horizon, being total costs for aflibercept + FOLFIRI of Euros 38,346, compared to Euros 24,782 with FOLFIRI. In the cost-effectiveness analysis Euros 38,931/LYG was obtained with aflibercept in combination with FOLFIRI versus FOLFIRI. CONCLUSION Aflibercept in combination with FOLFIRI increased overall survival versus FOLFIRI, so it is an effective strategy in the treatment of patients with mCRC. Aflibercept in combination with FOLFIRI is an efficient strategy for second-line mCRC treatment from the National Health System perspective.

Abstract
Preoperative use of levosimendan in cardiac surgery patients is one of the most attractive therapeutic alternatives in subjects with left or right ventricular dysfunction. Our review explores the pharmacological bases and clinical evidence for the use of levosimendan, with the intention of making a series of recommendations regarding its use in preoperative optimization prior to cardiac surgery. We carried out a survey of 102 Spanish anesthesiologists in order to shed light on the grey areas regarding the use of this drug prior to surgery. Our findings suggest that levosimendan is recommended for patients with severe left or right ventricular dysfunction, moderate left ventricular dysfunction in which Intra-aortic Balloon Counterpulsation (IABC) is necessary and severe pulmonary hypertension. Administration of levosimendan prior to surgical cardiac intervention without an initial bolus reduces the likelihood of complications.

Abstract
In Drosophila melanogaster, miR-8-3p regulates mRNA levels of atrophin, a factor involved in neuromotor coordination, and we found that Blattella germanica with suppressed atrophin showed motor problems. Bionformatic predictions and luciferase-reporter tests indicated that B. germanica atrophin mRNA contains target sites for miR-8-3p and miR-8-5p. Suppression of miR-8-3p or miR-8-5p appeared to increase atrophin mRNA. The effects of suppression of Argonaute (AGO) 1 or AGO2 expression on miR-8-3p and miR-8-5p suggested that miR-8-3-p might predominantly bind to AGO1, whereas miR-8-5p might bind to a moderate extent to both AGO1 and AGO2 in the respective RNA-induced silencing complexes (RISCs). We propose that the interplay of miR-8-3p, miR-8-5p, AGO1 and AGO2, maintain the appropriate levels of atrophin mRNA. This would be the first example of two strands of the same miRNA precursor regulating a single transcript.

Abstract
In most insect species, the microRNA (miRNA) let-7 clusters with miR-100 and miR-125 in the same primary transcript. The three miRNAs are involved in developmental timing in the nematode Caenorhabditis elegans and in the fly Drosophila melanogaster. In the cockroach Blattella germanica, the expression of these miRNAs increases dramatically in the wing pads around the molting peak of 20-hydroxyecdysone (20E) of the last instar nymph. When let-7 and miR-100 were depleted with specific anti-miRNAs in this instar, the resulting adults showed wings reduced in size (when miR-100 was depleted) or with malformed vein patterning (when let-7 and miR-100 were depleted). Depletion of miR-125 induced no apparent effects. Interestingly, the wing phenotype obtained after depleting let-7 and miR-100 is similar to that resulting from silencing the expression of Broad-Complex (BR-C) transcription factors with RNA interference (hindwings with a short CuP vein, with the vein/inter-vein pattern disorganized in the anterior part and showing anomalous bifurcations of the A-veins in the posterior part).
