SINBAD electronic models of the interface and control system for the NOMAD spectrometer on board of ESA ExoMars Trace Gas Orbiter mission

NOMAD is a spectrometer suite: UV-visible-IR spectral ranges. NOMAD is part of the payload of ESA ExoMars Trace Gas Orbiter Mission. SINBAD boards are in charge of the communication and management of the power and control between the spacecraft and the instrument channels. SINBAD development took four years, while the entire development and test required five years, a very short time to develop an instrument devoted to a space mission. The hardware of SINBAD is shown in the attached poster: developed boards, prototype boards and final models. The models were delivered to the ESA in order to testing and integration with the spacecraft

Multiancestry analysis of the HLA locus in Alzheimer’s and Parkinson’s diseases uncovers a shared adaptive immune response mediated by HLA-DRB1*04 subtypes

Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson’s disease (PD) and Alzheimer’s disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1*04 subtypes best accounted for the association, strongest with HLA-DRB1*04:04 and HLA-DRB1*04:07, and intermediary with HLA-DRB1*04:01 and HLA-DRB1*04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased Aβ42. Protective HLA-DRB1*04 subtypes strongly bound the aggregation-prone tau PHF6 sequence, however only when acetylated at a lysine (K311), a common posttranslational modification central to tau aggregation. An HLA-DRB1*04-mediated adaptive immune response decreases PD and AD risks, potentially by acting against tau, offering the possibility of therapeutic avenues

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Association of type I choledochal cyst, type III esophageal atresia, evanescent testicle, and clinodactyly: A case report

Introduction: Choledochal cyst is a congenital anomaly of the bile duct without associated pathology as compared to esophageal atresia, whose pathology is usually part of the VACTERL association list (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities). In addition to these core component features, patients may also have other congenital anomalies. Case presentation: A single case of the association of type 1 choledochal cyst (Todani), type III esophageal atresia (Ladd-Gross), evanescent testicle, and clinodactyly of both little fingers, is reported for the first time. A cytogenetic study reports an apparently normal male with a 46 XY karyotype, GTG bands, 400–550 band resolution, and extended exome sequencing without alterations. Esophageal plasty, hepatic-duodenal bypass in early childhood, and resection of the evanescent testicle with fixation of the contralateral testicle were performed at one year of age. We observed a satisfactory evolution after four years and four months of follow-up. Conclusion: In this report, we present this novel case of the association of type 1 choledochal cyst (Todani), type III esophageal atresia (Ladd-Gross), evanescent testicle, and clinodactyly of both little fingers, which has not been previously reported in the literature

NOMAD spectrometer on the ExoMars trace gas orbiter mission: part 1—design, manufacturing and testing of the infrared channels

NOMAD is a spectrometer suite on board ESA’s ExoMars trace gas orbiter due for launch in January 2016. NOMAD consists of two infrared channels and one ultraviolet and visible channel allowing the instrument to perform observations quasi-constantly, by taking nadir measurements at dayside and nightside, and during solar occultations. In this paper, the design, manufacturing, and testing of the two infrared channels are described. We focus upon the optical working principle in these channels, where an echelle grating, used as a diffractive element, is combined with an acousto-optical tunable filter, used as a diffraction order sorter

Comprensión y Producción de Lenguaje I - HU543 - 202101

Descripción: Comprensión y Producción de Lenguaje 1 es un curso de primer ciclo, que busca desarrollar las habilidades vinculadas con la comprensión lectora y la redacción de textos escritos formales y adecuados a una situación comunicativa determinada. Por ello, durante el curso, las actividades posibilitarán que el estudiante reflexione sobre cómo el lenguaje es una herramienta que nos permite entender la realidad (comprensión) y comunicar adecuadamente nuestras ideas sobre ella (producción). Esta reflexión se realizará con énfasis en el uso del lenguaje en las redes sociales, espacio que se ha constituido como un nuevo lugar para la divulgación de asuntos diversos: desde temas de ocio o entretenimiento hasta temas académicos, científicos y políticos. En ese sentido, este curso propone que el alumno asuma el rol de un ciudadano crítico, es decir, aquella persona que no solo consume información, sino que produce contenido a partir de una investigación en fuentes confiables. Considerando lo explicado, nuestros alumnos no solo serán capaces de redactar un texto escrito formal de acuerdo con las necesidades comunicativas del ámbito universitario y de la sociedad actual, sino que podrán transformarlo en un texto multimodal (el cual involucra diferentes medios de comunicación: visual, auditivo, imagen, texto, entre otros) que tenga sentido en las redes sociales, lugar de interacción real con sus lectores. Estos productos comunicativos deberán presentar una organización conveniente, un desarrollo sólido y suficiente (lo que implica una lectura crítica de las fuentes de información), y una escritura acorde con la normativa vigente. 3 Propósito: El curso desarrolla la competencia de comunicación escrita, en el nivel 1; es decir, el estudiante es capaz de construir mensajes coherentes y sólidos que se adecúan a la situación y propósito comunicativo. Este desarrollo le permite la generación y construcción de nuevas ideas, lo cual es relevante para su vida académica y profesional. La actual sociedad de la información y el conocimiento, caracterizada por la disrupción, la innovación y la complejidad en las formas de comunicación mediadas por la tecnología, enfrenta al estudiante y al profesional a nuevos retos en las maneras de comunicar aquello que conoce y que construye. En este escenario, la competencia comunicativa escrita adquiere protagonismo como herramienta para transmitir el conocimiento creado. El curso se alinea con esta exigencia, pues contribuye a que el estudiante responda exitosamente a las demandas comunicativas del contexto académico, y a que el egresado pueda desenvolverse idóneamente en el campo profesional y laboral
