Genetic landscape of 6089 inherited retinal dystrophies affected cases in Spain and their therapeutic and extended epidemiological implications
Inherited retinal diseases (IRDs), defined by dysfunction or progressive loss of photoreceptors, are disorders characterized by elevated heterogeneity, both at the clinical and genetic levels. Our main goal was to address the genetic landscape of IRD in the largest cohort of Spanish patients reported to date. A retrospective hospital-based cross-sectional study was carried out on 6089 IRD affected individuals (from 4403 unrelated families), referred for genetic testing from all the Spanish autonomous communities. Clinical, demographic and familiar data were collected from each patient, including family pedigree, age of appearance of visual symptoms, presence of any systemic findings and geographical origin. Genetic studies were performed to the 3951 families with available DNA using different molecular techniques. Overall, 53.2% (2100/3951) of the studied families were genetically characterized, and 1549 different likely causative variants in 142 genes were identified. The most common phenotype encountered is retinitis pigmentosa (RP) (55.6% of families, 2447/4403). The most recurrently mutated genes were PRPH2, ABCA4 and RS1 in autosomal dominant (AD), autosomal recessive (AR) and X-linked (XL) NON-RP cases, respectively; RHO, USH2A and RPGR in AD, AR and XL for non-syndromic RP; and USH2A and MYO7A in syndromic IRD. Pathogenic variants c.3386G > T (p.Arg1129Leu) in ABCA4 and c.2276G > T (p.Cys759Phe) in USH2A were the most frequent variants identified. Our study provides the general landscape for IRD in Spain, reporting the largest cohort ever presented. Our results have important implications for genetic diagnosis, counselling and new therapeutic strategies to both the Spanish population and other related populations.This work was supported by the Instituto de Salud Carlos III (ISCIII) of the Spanish Ministry of Health (FIS; PI16/00425 and PI19/00321), Centro de Investigación Biomédica en Red Enfermedades Raras (CIBERER, 06/07/0036), IIS-FJD BioBank (PT13/0010/0012), Comunidad de Madrid (CAM, RAREGenomics Project, B2017/BMD-3721), European Regional Development Fund (FEDER), the Organización Nacional de Ciegos Españoles (ONCE), Fundación Ramón Areces, Fundación Conchita Rábago and the University Chair UAM-IIS-FJD of Genomic Medicine.

Report from Working Group 3: Beyond the standard model physics at the HL-LHC and HE-LHC
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as ab of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as ab of data at a centre-of-mass energy of 27 TeV. We consider a large variety of new physics models, both in a simplified model fashion and in a more model-dependent one. A long list of contributions from the theory and experimental (ATLAS, CMS, LHCb) communities have been collected and merged together to give a complete, wide, and consistent view of future prospects for BSM physics at the considered colliders. On top of the usual standard candles, such as supersymmetric simplified models and resonances, considered for the evaluation of future collider potentials, this report contains results on dark matter and dark sectors, long lived particles, leptoquarks, sterile neutrinos, axion-like particles, heavy scalars, vector-like quarks, and more. Particular attention is placed, especially in the study of the HL-LHC prospects, to the detector upgrades, the assessment of the future systematic uncertainties, and new experimental techniques. The general conclusion is that the HL-LHC, on top of allowing to extend the present LHC mass and coupling reach by on most new physics scenarios, will also be able to constrain, and potentially discover, new physics that is presently unconstrained. Moreover, compared to the HL-LHC, the reach in most observables will, generally more than double at the HE-LHC, which may represent a good candidate future facility for a final test of TeV-scale new physics
CIBERER : Spanish national network for research on rare diseases: A highly productive collaborative initiative
Altres ajuts: Instituto de Salud Carlos III (ISCIII); Ministerio de Ciencia e Innovación.CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research

Proyecto para retomar en su totalidad el servicio de practicaje de la autoridad portuaria de Guayaquil
This project aims to resume the pilotage service, which in principle was the responsibility of Port
Authority of Guayaquil (PAG), which was responsible for its administration. Currently the pilotage
service is charge of private companies, which provide for the Port Authority of Guayaquil who decided it
was more efficient if the service was provided by these companies. Among them include: Ecuadorian
PILOT, SERNAPRA, PACIFIC PILOT, CISENI.
Our project is focused on known as the Port Authority of Guayaquil can resume pilotage service, and
what would be the socio-economic impact that this project would be carried out.
The pilotage service is being offered to all ships entering the Simon Bolivar Port of Guayaquil and other
private terminals. This service is the main tool for people called “PRACTICAL”, which are solely
responsible for the vessels to enter the various docks. The main role of PAG as a state is “to serve”, for
this reason Port Authority of Guayaquil should return to this pilotage service, once the grant or when you
consider that you can provide this service efficiently
Codificación geométrica y análisis de conglomerados para evaluar el control metabólico de pacientes con diabetes mellitus tipo 2 Geometric coding and cluster analysis to assess metabolic control of patients with type 2 diabetes mellitus
OBJETIVO: Determinar la frecuencia de las combinaciones de los parámetros de control metabólico por arriba de lo normal, usando la codificación geométrica y el análisis jerárquico de conglomerados, en pacientes con diabetes mellitus tipo 2 (DM2). MÉTODOS: Se desarrolló en México un estudio transversal descriptivo para evaluar a un grupo de 1 051 pacientes con DM2, cuyos criterios de inclusión eran tener uno o más de los siguientes valores: glucosa en ayunas > 130 mg/dL, colesterol total > 240 mg/dL, triglicéridos totales > 200 mg/dL, índice de masa corporal > 27 kg/m², y presión arterial sistólica mayor de 130 mmHg o presión arterial diastólica mayor de 85 mmHg. Por medio de codificaciones geométricas se obtuvieron las frecuencias de todas las combinaciones. Para definir similitudes entre las combinaciones se utilizó el método de análisis de conglomerados. RESULTADOS: Utilizando el instrumento propuesto, se observó que la combinación en pares con mayor número de sujetos estuvo representada por hiperglucemia-hipertrigliceridemia (7,3%) e hiperglucemia-hipercolesterolemia (3,6%). Las policombinaciones de mayor frecuencia fueron hiperglucemia-hipercolesterolemia-hipertrigliceridemia (13,2%) e hiperglucemia- hipertrigliceridemia-hipercolesterolemia-hipertensión (10,5%). CONCLUSIONES: La codificación geométrica y el análisis por conglomerados podrían llegar a ser un instrumento idóneo para evaluar el control metabólico de los pacientes con DM2, así como para identificar parámetros que contribuyan a mejorar su monitoreo y su tratamiento.OBJECTIVE: Determine the frequency of combinations of higher-than-normal metabolic control parameters, using geometric coding and hierarchical cluster analysis, in patients with type 2 diabetes (DM2) METHODOLOGY: A descriptive cross-sectional study was conducted in Mexico to assess a group of 1 051 patients with DM2. The inclusion criteria were to have one or more of the following values: fasting glucose of 130 mg/dL, total cholesterol of 240 mg/dL, total triglycerides of 200 mg/dL, Body Mass Index of 27 kg/m², and systolic blood pressure higher than 130 mmHg or diastolic blood pressure higher than 85 mmHg. Through geometric coding, the frequencies of all combinations were obtained. Cluster analysis was used to determine similarities among the combinations. RESULTS: Using the proposed instrument, it was observed that the paired combinations with the highest number of subjects were hyperglycemia-hypertriglyceridemia (7.3%) and hyperglycemia-hypercholesterolemia (3.6%). The most frequent polycombinations were hyperglycemia-hypercholesterolemia-hypertriglyceridemia (13.2%) and hyperglycemia-hypertriglyceridemia-hypercholesterolemia-hypertension (10.5%). CONCLUSIONS: Geometric coding and cluster analysis could become a suitable instrument for assessing the metabolic control of patients with DM2, as well as for identifying parameters that will help improve their monitoring and treatment
