Seudomicetoma dermatofítico en un gato persa : aspectos clínicos, patológicos y evolutivos

En este trabajo presentamos los aspectos clínicos, anatomopatológicos y evolutivos de un caso de dermatitis piogranulomatosa múltiple causada por hongos del género Microsporum, también conocida como seudomicetoma dermatofítico, en un gato persa, no castrado, de un año de edad al comienzo de la enfermedad. Las lesiones se caracterizaron macroscópicamente por la formación de numerosos nódulos de diferentes tamaños, localizados en la cabeza y antebrazo derecho, extendiéndose posteriormente a zona dorso lateral del tronco. La evolución de estos nódulos, que se generalizaron en algo menos de un mes, era hacia la coalescencia y fistulización, con descarga de un material grumoso blanco-grisáceo. El estudio histopatológico reveló una dermatitis piogranulomatosa, supeficial y profunda, caracterizada por presentar en el centro de los granulomas agregados de hongos septados inmersos en una matriz acidófila. La extirpación quirúrgica de un gran número de nódulos proporcionó mejorías transitorias, aunque reaparecieron nuevas lesiones. En este trabajo se describe la evolución tras dos años de seguimiento clínico. Tras el tratamiento con griseofulvina no se detectan nuevas lesiones después de 6 meses de su aplicación y seguimiento.This paper reports the clinical and histopathological features of a case of pyogranulomatous dermatitis caused by Microsporum fungi, a condition also known as dermatophyte pseudomycetoma, in a eneyear-old Persian cat. Grossly apparent fistulized nodules of varying sizes displaying a granular discharge were localized on the head, back, elbow and tail. Microscopic analysis revealed a deep piogranulomatous dermatitis characterized by centrally-located clusters of fungi within an acidophilic matrix. In just under a month, nodules had beco me generalized. Partial surgical excision and non-specific treatment provided temporary improvement, but new lesions subsequentlyappeared

Reducing MYC's transcriptional footprint unveils a good prognostic gene signature in melanoma

MYC; Omomyc; MelanomaMYC; Omomyc; MelanomaMYC; Omomyc; MelanomaMYC's key role in oncogenesis and tumor progression has long been established for most human cancers. In melanoma, its deregulated activity by amplification of 8q24 chromosome or by upstream signaling coming from activating mutations in the RAS/RAF/MAPK pathway—the most predominantly mutated pathway in this disease—turns MYC into not only a driver but also a facilitator of melanoma progression, with documented effects leading to an aggressive clinical course and resistance to targeted therapy. Here, by making use of Omomyc, the most characterized MYC inhibitor to date that has just successfully completed a phase I clinical trial, we show for the first time that MYC inhibition in melanoma induces remarkable transcriptional modulation, resulting in severely compromised tumor growth and a clear abrogation of metastatic capacity independently of the driver mutation. By reducing MYC's transcriptional footprint in melanoma, Omomyc elicits gene expression profiles remarkably similar to those of patients with good prognosis, underlining the therapeutic potential that such an approach could eventually have in the clinic in this dismal disease.M.F.Z.-F. was supported by the Juan de la Cierva Programme of the Spanish Ministry of Economy and Competitiveness (IJCI-2014-22403) and Fundació La Marató de TV3 (grant 474/C/2019); F.G. was supported by Spanish Ministry of Science and Innovation Contratos Predoctorales de Formación en Investigación en Salud (PFIS; FI20/00274); I.G.-L. was supported by a grant from the University Teacher Training Program (FPU), Ministry of Universities (FPU20/04812); and S.M.-M. was supported by the Generalitat de Catalunya “Contractació de Personal Investigador Novell (FI-DGR)” 2016 fellowship (2016FI_B 00592).

Adecuación en España a las recomendaciones terapéuticas de la guía de la ESC sobre insuficiencia cardiaca: ESC Heart Failure Long-term Registry

[Abstract] Introduction and objectives. To estimate the percentage of heart failure patients in Spain that received the European Society of Cardiology recommended treatments, and in those that did not, to determine the reasons why. Methods. The study included 2834 consecutive ambulatory patients with heart failure from 27 Spanish hospitals. We recorded general information, the treatment indicated, and the reasons why it was not prescribed in some cases. In patients who met the criteria to receive a certain drug, true undertreatment was defined as the percentage of patients who, without justification, did not receive the drug. Results. In total, 92.6% of ambulatory patients with low ejection fraction received angiotensin converting enzyme inhibitors or angiotensin receptor blockers, 93.3% beta-blockers, and 74.5% mineralocorticoid receptor antagonists. The true undertreatment rates were 3.4%, 1.8%, and 19.0%, respectively. Target doses were reached in 16.2% of patients receiving angiotensin converting enzyme inhibitors, 23.3% of those with angiotensin receptor blockers, 13.2% of those prescribed beta-blockers, and 23.5% of those with mineralocorticoid receptor antagonists. Among patients who could benefit from ivabradine, 29.1% received this drug. In total, 36% of patients met the criteria for defibrillator implantation and 90% of them had received the device or were scheduled for implantation, whereas 19.6% fulfilled the criteria for resynchronization therapy and 88.0% already had or would soon have the device. In patients who met the criteria, but did not undergo device implantation, the reasons were not cost-related. Conclusions. When justified reasons for not administering heart failure drugs were taken into account, adherence to the guideline recommendations was excellent. Exclusive use of the percentage of treated patients is a poor indicator of the quality of healthcare in heart failure. Measures should be taken to improve the attainment of optimal dosing in each patient.[Resumen] Introducción y objetivos. Estimar la proporción de pacientes con insuficiencia cardiaca atendidos en España que reciben los tratamientos recomendados por la Sociedad Europea de Cardiología y razones de que no los reciban, en su caso. Métodos. Se incluyó a 2.834 pacientes ambulatorios consecutivos con insuficiencia cardiaca de 27 hospitales españoles. Se recogió información general, tratamiento indicado y causas de que no lo recibiera, en su caso. De los pacientes que cumplen criterios para recibir tratamiento, infratratamiento real es la proporción que, sin justificación, no lo recibe. Resultados. El 92,6% de los pacientes ambulatorios con fracción de eyección reducida recibieron inhibidores de la enzima de conversión de la angiotensina o antagonistas del receptor de la angiotensina II; el 93,3%, bloqueadores beta y el 74,5%, antagonistas del receptor mineralocorticoideo. El infratratamiento real es del 3,4, el 1,8 y el 19,0% respectivamente. Alcanzan dosis objetivo de inhibidores de la enzima de conversión de la angiotensina el 16,2% de los pacientes; de antagonistas de los receptores de la angiotensina II, el 23,3%; de bloqueadores beta, el 13,2% y de antagonistas del receptor mineralocorticoideo, el 23,5%. El 29,1% de los pacientes que podrían beneficiarse de ivabradina la reciben; el 36% cumple criterios para implantar desfibrilador; de ellos, el 90% lo tienen ya implantado o programado; las cifras correspondientes en resincronización son el 19,6 y el 88,0%; el porcentaje restante no se debe a causas económicas. Conclusiones. Considerando razones justificadas para no administrar fármacos a estos pacientes, el cumplimiento de las guías es excelente. Utilizar solo la proporción de pacientes tratados es un mal indicador de calidad de la asistencia en insuficiencia cardiaca. Es necesario introducir medidas que mejoren el logro de la dosis óptima para cada paciente

ADVANCE system testing: Can safety studies be conducted using electronic healthcare data? An example using pertussis vaccination

Introduction: The Accelerated Development of Vaccine benefit-risk Collaboration in Europe (ADVANCE) public-private collaboration, aimed to develop and test a system for rapid benefit-risk monitoring of vaccines using healthcare databases in Europe. The objective of this proof-of-concept (POC) study was to test the feasibility of the ADVANCE system to generate incidence rates (IRs) per 1000 person-years and incidence rate ratios (IRRs) for risks associated with whole cell- (wP) and acellular- (aP) pertussis vaccines, occurring in event-specific risk windows in children prior to their pre-school-entry booster. Methods: The study population comprised almost 5.1 million children aged 1 month to <6 years vaccinated with wP or aP vaccines during the study period from 1 January 1990 to 31 December 2015. Data from two Danish hospital (H) databases (AUH and SSI) and five primary care (PC) databases from, UK (THIN and RCGP RSC), Spain (SIDIAP and BIFAP) and Italy (Pedianet) were analysed. Database-specific IRRs between risk vs. non-risk periods were estimated in a self-controlled case series study and pooled using random-effects meta-analyses. Results: The overall IRs were: fever, 58.2 (95% CI: 58.1; 58.3), 96.9 (96.7; 97.1) for PC DBs and 8.56 (8.5; 8.6) for H DBs; convulsions, 7.6 (95% CI: 7.6; 7.7), 3.55 (3.5; 3.6) for PC and 12.87 (12.8; 13) for H; persistent crying, 3.9 (95% CI: 3.8; 3.9) for PC, injection-site reactions, 2.2 (95% CI 2.1; 2.2) for PC, hypotonic hypo-responsive episode (HHE), 0.4 (95% CI: 0.4; 0.4), 0.6 (0.6; 0.6) for PC and 0.2 (0.2; 0.3) for H; and somnolence: 0.3 (95% CI: 0.3; 0.3) for PC. The pooled IRRs for persistent crying, fever, and ISR, adjusted for age and healthy vaccinee period were higher after wP vs. aP vaccination, and lower for convulsions, for all doses. The IRR for HHE was slightly lower for wP than aP, while wP was associated with somnolence only for dose 1 and dose 3 compared with aP. Conclusions: The estimated IRs and IRRs were comparable with published data, therefore demonstrating that the ADVANCE system was able to combine several European healthcare databases to assess vaccine safety data for wP and aP vaccination

IgA Vasculitis: Influence of CD40, BLK and BANK1 Gene Polymorphisms

CD40, BLK and BANK1 genes involved in the development and signaling of B-cells are identified as susceptibility loci for numerous inflammatory diseases. Accordingly, we assessed the potential influence of CD40, BLK and BANK1 on the pathogenesis of immunoglobulin-A vasculitis (IgAV), predominantly a B-lymphocyte inflammatory condition. Three genetic variants within CD40 (rs1883832, rs1535045, rs4813003) and BLK (rs2254546, rs2736340, rs2618476) as well as two BANK1 polymorphisms (rs10516487, rs3733197), previously associated with inflammatory diseases, were genotyped in 382 Caucasian patients with IgAV and 955 sex- and ethnically matched healthy controls. No statistically significant differences were observed in the genotype and allele frequencies of CD40, BLK and BANK1 when IgAV patients and healthy controls were compared. Similar results were found when CD40, BLK and BANK1 genotypes or alleles frequencies were compared between patients with IgAV stratified according to the age at disease onset or to the presence/absence of gastrointestinal or renal manifestations. Moreover, no CD40, BLK and BANK1 haplotype differences were disclosed between patients with IgAV and healthy controls and between patients with IgAV stratified according to the clinical characteristics mentioned above. Our findings indicate that CD40, BLK and BANK1 do not contribute to the genetic background of IgAV

Abundance ratios and IMF slopes in the dwarf elliptical galaxy NGC 1396 with MUSE

Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (MV = −16.60, Mass ~4 × 10^8 M�), located in the Fornax cluster, have been performed with the VLT/ MUSE spectrograph in the wavelength region from 4750 − 9350 Å. In this paper we present a stellar population analysis studying chemical abundances, the star formation history (SFH) and the stellar initial mass function (IMF) as a function of galacto-centric distance. Different, independent ways to analyse the stellar populations result in a luminosity-weighted age of ∼ 6 Gyr and a metallicity [Fe/H]∼ −0.4, similar to other dEs of similar mass. We find unusually overabundant values of [Ca/Fe] ∼ +0.1, and under-abundant Sodium, with [Na/Fe] values around −0.1, while [Mg/Fe] is overabundant at all radii, increasing from ∼ +0.1 in the centre to ∼ +0.2 dex. We notice a significant metallicity and age gradient within this dwarf galaxy. To constrain the stellar IMF of NGC 1396, we find that the IMF of NGC 1396 is consistent with either a Kroupa-like or a top-heavy distribution, while a bottom-heavy IMF is firmly ruled out. An analysis of the abundance ratios, and a comparison with galaxies in the Local Group, shows that the chemical enrichment history of NGC 1396 is similar to the Galactic disc, with an extended star formation history. This would be the case if the galaxy originated from a LMC-sized dwarf galaxy progenitor, which would lose its gas while falling into the Fornax cluster

Pension systems compared : a polarised perspective, a diverse reality

Production of INCASI Project H2020-MSCA-RISE-2015 GA 691004Globalisation and international competition have a spillover effect on the reforms of pension systems that imposes a similar pattern of dismantling, hardening access to pensions, reducing expenditure and retrenchment in said reforms. The comparative analysis of four countries with different pension systems: two liberal (United Kingdom and Chile) and another two with contributory-proportional systems (Spain and Argentina) serves to determine the details of the reform processes, which discursively seem to have a shared pattern recommended by the international financial and economic institutions. But the reality of the four case studies shows considerable differences in the implementation of the pension reform policies. The reforms depend on the societal context, institutions, history, the role of unions, the government in power, demographic factors and economic perspectives, among other matters. Many countries need to sustain pension systems because they are associated with many pensioners' political vote. Therefore, the spillover effect of globalisation and the convergence in certain uniform patterns of reforms is far from reality in the four countries, and as such, the measures adopted are specific for each country

Burden of paediatric Rotavirus Gastroenteritis (RVGE) and potential benefits of a universal Rotavirus vaccination programme with a pentavalent vaccine in Spain

<p>Abstract</p> <p>Background</p> <p>Rotavirus is the most common cause of gastroenteritis in young children worldwide. The aim of the study was to assess the health outcomes and the economic impact of a universal rotavirus vaccination programme with RotaTeq, the pentavalent rotavirus vaccine, versus no vaccination programme in Spain.</p> <p>Methods</p> <p>A birth cohort was followed up to the age of 5 using a cohort model. Epidemiological parameters were taken from the REVEAL study (a prospective epidemiological study conducted in Spain, 2004-2005) and from the literature. Direct and indirect costs were assessed from the national healthcare payer and societal perspectives by combining health care resource utilisation collected in REVEAL study and unit costs from official sources. RotaTeq per protocol efficacy data was taken from a large worldwide rotavirus clinical trial (70,000 children). Health outcomes included home care cases, General Practioner (GP)/Paediatrician, emergency department visits, hospitalisations and nosocomial infections.</p> <p>Results</p> <p>The model estimates that the introduction of a universal rotavirus vaccination programme with RotaTeq (90% coverage rate) would reduce the rotavirus gastroenteritis (RVGE) burden by 75% in Spain; 53,692 home care cases, 35,187 GP/Paediatrician visits, 34,287 emergency department visits, 10,987 hospitalisations and 2,053 nosocomial infections would be avoided. The introduction of RotaTeq would avoid about 76% of RVGE-related costs from both perspectives: €22 million from the national health system perspective and €38 million from the societal perspective.</p> <p>Conclusions</p> <p>A rotavirus vaccination programme with RotaTeq would reduce significantly the important medical and economic burden of RVGE in Spain.</p
