Axion condensate as a model for dark matter halos

AbstractLocalized solutions of an axion-like scalar model with a periodic self-interaction are analyzed as a model of dark matter halos. It is shown that such a cold Bose–Einstein type condensate can provide a substantial contribution to the observed rotations curves of galaxies, as well provide a soliton type interpretation of the dark matter ‘bullets’ observed via gravitational lensing in merging clusters

Enhancement of synchronized vortex lattice motion in hybrid magnetic/amorphous superconducting nanostructures

Superconducting a-Mo_(3)Si and Nb films have been grown on arrays of Ni nanodots. We have studied the vortex lattice dynamics close to critical temperatures. Different vortex lattice configurations are obtained with the same array unit cell. These different vortex lattices occur at matching conditions between the vortex lattice and the array unit cell. The interplay between the random intrinsic pinning of the superconducting films and the periodic pinning of the array govern the vortex lattice configurations. Different vortex lattice configurations and enhancement of synchronized vortex lattice motion are obtained by increasing the periodic pinning strength and decreasing the random pinning strength

Immigrant women living with HIV in Spain: a qualitative approach to encourage medical follow-up

Abstract Background: Immigrant women living with HIV generally have worse adherence to medical treatment and follow-up when compared to native women and immigrant or native men. The general aim of this study was to improve healthcare services for HIV-positive women and to better understand why some of them discontinue treatment. The specific objectives were: (1) to explore the barriers and facilitators to medical follow-up among women and (2) to use the findings to create a guide for healthcare professionals with strategies and tools to encourage the immigrant women to continue with their healthcare treatment. Methods: We conducted a qualitative, patient-centred research based on semi-structured interviews in order to understand the drivers and barriers for HIV positive immigrant women to adhere to medical follow-up. A total of 26 women in active or discontinued treatment (from sub-Saharan Africa (10), Latin America (8) and Spain (8)) were interviewed in 2012 using a purposive sampling methodology. The semi-structured interviews were transcribed and analysed based on the grounded theory approach and the framework method. Three researchers took part in the triangulation of results. The study was approved by the Ethical Committee of the Hospital Universitario Ramón y Cajal

Imported cysticercosis in Spain: A retrospective case series from the +REDIVI Collaborative Network

Neurocysticercosis (NCC) is the most common parasitic neurological disease worldwide and a major cause of epilepsy. Spain is the country reporting the highest number of NCC imported cases in Europe. Retrospective case series of NCC patients registered in the +REDIVI Network from October 1, 2009 to July 2018. A specific questionnaire, including clinical and diagnostic characteristics, was created and sent to the collaborator centers. 46 cases were included in the analysis. 55% were male, mean age of 40 years. 95.6% were migrants. The median duration since migration from an endemic area was 10 years. Predominant nationalities were Ecuadorians (50%) and Bolivians (30.4%). Frequent locations were parenchymal (87%), subarachnoid (26.1%) and intraventricular cysts (10.9%). Serological analysis was performed in 91.3%, being 54.8% positive. Most prevalent clinical manifestations were persistent headache (60.9%), epilepsy (43.5%) and visual changes (13%). Patients were mainly treated with albendazole (76.1%), corticosteroids (67.4%), and anticonvulsionants (52.2%). 82.5% had a favorable clinical outcome. Most NCC cases were long-standing migrants. Few clinical differences were observed depending on the cysticerci location. The treatment was often not according to current recommendations, and no uniform criteria were followed when it came to the therapeutic regimen. NCC case management in Spain (including clinician awareness and laboratory capacity improvements) needs to be strengthened.We would thanks María Jesús Perteguer from the National Center of Microbiology for the information and update on NCC lab techniques currently performed in Spain.

Imported Infectious Diseases in Mobile Populations, Spain

Health screening of immigrant populations is needed to ensure early diagnosis and treatment

Neglected Tropical Diseases outside the Tropics

Neglected Tropical Diseases (NTDs) have been targeted due to their prevalence and the burden of disease they cause globally, but there has been no significant focus in the literature on the subject of NTDs as a group in immigrants and travelers, and no specific studies on the emerging phenomenon of imported NTDs. We present the experience of a Tropical Medicine Unit in a major European city, over a 19-year period, describing and comparing NTDs diagnosed amongst immigrants, travelers and travelers visiting friends and relatives (VFRs). NTDs were diagnosed outside tropical areas and occurred more frequently in immigrants, followed by VFR travelers and then by other travelers. The main NTDs diagnosed in immigrants were onchocerciasis, Chagas disease and ascariasis; most frequent NTDs in travelers were schistosomiasis, onchocerciasis and ascariasis, and onchocerciasis and schistosomiasis in VFRs. Issues focusing on modes of transmission outside endemic areas and how eradication programs for some NTDs in endemic countries may have an impact in non-tropical Western countries by decreasing disease burden in immigrants, are addressed. Adherence to basic precautions such as safe consumption of food/water and protection against arthropod bites could help prevent many NTDs in travelers

Autoantibodies against the immunodominant sCha epitope discriminate the risk of sudden death in chronic Chagas cardiomyopathy

In Chagas disease (ChD) caused by Trypanosoma cruzi, new biomarkers to predict chronic cardiac pathology are urgently needed. Previous studies in chagasic patients with mild symptomatology showed that antibodies against the immunodominant R3 epitope of sCha, a fragment of the human basic helix-loop-helix transcription factor like 5, correlated with cardiac pathology. To validate sCha as a biomarker and to understand the origin of anti-sCha antibodies, we conducted a multicenter study with several cohorts of chagasic patients with severe cardiac symptomatology. We found that levels of antibodies against sCha discriminated the high risk of sudden death, indicating they could be useful for ChD prognosis. We investigated the origin of the antibodies and performed an alanine scan of the R3 epitope. We identified a minimal epitope MRQLD, and a BLAST search retrieved several T. cruzi antigens. Five of the hits had known or putative functions, of which phosphonopyruvate decarboxylase showed the highest cross-reactivity with sCha, confirming the role of molecular mimicry in the development of anti-sCha antibodies. Altogether, we demonstrate that the development of antibodies against sCha, which originated by molecular mimicry with T. cruzi antigens, could discriminate electrocardiographic alterations associated with a high risk of sudden death.Ministerio de Economía y competitividad and Fondo Europeo de Desarrollo Regional (SAF2015-63868-R (MINECO/FEDER) to N.G., and SAF2016-75988-R (MINECO/FEDER) to M.F.); Ministerio de Ciencia, Innovación y Universidades-Agencia Estatal de Investigación and Fondo Europeo de Desarrollo Regional (PGC2018-096132-BI00 (MICINN/FEDER) to N.G.); Universidad Autónoma de Madrid-Banco de Santander Inter-University Cooperation Grant with Latin América (CEAL-AL/2015-12 to N.G.); Red de Investigación de Centros de Enfermedades Tropicales (RICET RD12/0018/0004 to M.F.); and Comunidad de Madrid (S-2010/BMD-2332 to M.F.).

Foro 18 de Historia y Crítica de la Arquitectura Moderna.

Grupo de Investigación Aprendizaje en el hábitat Comunitario.Selección de textos del Foro 18 de Historia y Crítica de la Arquitectura Moderna. Libro núm. 7 de la colección de libros del ForoEn un contexto histórico en donde es clara la relación de la humanidad con la arquitectura, en tanto nos han aportado un inmenso legado ético y estético, y que, sin embargo, en la situación actual de la arquitectura se muestra en contradicción ya que prevalece el interés económico y la pronta ganancia por sobre el cuidado de la naturaleza, la sustentabilidad en las ciudades, la identificación estética de la arquitectura y el encuentro social a través del espacio público, se podría tener una primera caracterización de la arquitectura de emergencia. Los once trabajos aquí presentados colocan al centro el quehacer arquitectónico y desde ese punto ofrecen un contexto y diversidad de prácticas y respuestas. Dichos textos cuentan con reflexiones teóricas, exposición de búsquedas a manera de prácticas y valoraciones críticas de ejercicios de distintas escalas. Destaca en esta ocasión la práctica profesional del ejercicio “Reconstrucción de la vivienda Chiapas... una reflexión”, misma que nace del ejercicio mismo, de la búsqueda de soluciones en campo y no del ejercicio de investigación.Día 1: https://youtu.be/Vacp2el_N2ADía 2: https://youtu.be/ujfc8JZsbQwDía 3: https://youtu.be/vD2NxcFjLy

ClinPrior: an algorithm for diagnosis and novel gene discovery by network-based prioritization

BackgroundWhole-exome sequencing (WES) and whole-genome sequencing (WGS) have become indispensable tools to solve rare Mendelian genetic conditions. Nevertheless, there is still an urgent need for sensitive, fast algorithms to maximise WES/WGS diagnostic yield in rare disease patients. Most tools devoted to this aim take advantage of patient phenotype information for prioritization of genomic data, although are often limited by incomplete gene-phenotype knowledge stored in biomedical databases and a lack of proper benchmarking on real-world patient cohorts.MethodsWe developed ClinPrior, a novel method for the analysis of WES/WGS data that ranks candidate causal variants based on the patient's standardized phenotypic features (in Human Phenotype Ontology (HPO) terms). The algorithm propagates the data through an interactome network-based prioritization approach. This algorithm was thoroughly benchmarked using a synthetic patient cohort and was subsequently tested on a heterogeneous prospective, real-world series of 135 families affected by hereditary spastic paraplegia (HSP) and/or cerebellar ataxia (CA).ResultsClinPrior successfully identified causative variants achieving a final positive diagnostic yield of 70% in our real-world cohort. This includes 10 novel candidate genes not previously associated with disease, 7 of which were functionally validated within this project. We used the knowledge generated by ClinPrior to create a specific interactome for HSP/CA disorders thus enabling future diagnoses as well as the discovery of novel disease genes.ConclusionsClinPrior is an algorithm that uses standardized phenotype information and interactome data to improve clinical genomic diagnosis. It helps in identifying atypical cases and efficiently predicts novel disease-causing genes. This leads to increasing diagnostic yield, shortening of the diagnostic Odysseys and advancing our understanding of human illnesses
