Govern de les dades associades al cicle de vida dels Sistemes d'Informació gestionats pel CTTI i el seu impacte com a dada mestra corporativa de la Generalitat.

Una dada no és res més que un element informatiu que acostuma a tenir una interpretació directa. Ara bé, si es reuneix un conjunt de dades fiables i de qualitat i s'explota la informació que se n'obté, poden arribar a ser un dels actius més importants d'una organització, ja que facilita que es conegui millor i pugui prendre decisions basades en fets i no subjectivitats. Des de fa uns mesos el CTTI es troba en una etapa de transformació digital i un dels principals eixos estratègics que es desenvolupa és el govern de la dada. L'objectiu d'aquest projecte és dur a terme una primera iteració sobre els termes de negoci que requereix aquest eix de treball per gestionar el cicle de vida dels sistemes d'informació i es distingeix quins d'aquests termes de negoci han de formar part de l'entitat mestra de la Generalitat, així com l'impacte que tenen en aquesta organització. A més a més, s'analitzen els requisits de l'empresa per a escollir una eina que permeti governar certs aspectes de tot el programari que gestiona i es presenta una proposta.A datum is nothing more than an informative element that tends to have a direct interpretation. However, if a set of reliable and high-quality data is gathered and the information obtained is exploited, it may become one of the most important assets of an organization, as it makes it easier for it to be better known and to make decisions based on facts and not subjectivity. For some months now, the CTTI has been in a phase of digital transformation and one of the main strategic axes being developed is data governance. The aim of this project is to conduct a first iteration on the business terms that this work axis requires to manage the life cycle of information systems and it is distinguished which of these business terms should be part of the master entity of the Generalitat, as well as the impact they have on it. In addition, an analysis of the company's requirements for choosing a tool permitting the management of all the software it manages and a proposal are presented

Newborn Screening for SCID: Experience in Spain (Catalonia)

Linfocitos T; Cribado de recién nacidos; Inmunodeficiencia combinada severaLimfòcits T; Cribratge de nounats; Immunodeficiència combinada severaT-lymphocytes; Newborn screening; Severe combined immunodeficiencyNewborn screening (NBS) for severe combined immunodeficiency (SCID) started in Catalonia in January-2017, being the first Spanish and European region to universally include this testing. In Spain, a pilot study with 5000 samples was carried out in Seville in 2014; also, a research project with about 35,000 newborns will be carried out in 2021–2022 in the NBS laboratory of Eastern Andalusia. At present, the inclusion of SCID is being evaluated in Spain. The results obtained in the first three and a half years of experience in Catalonia are presented here. All babies born between January-2017 and June-2020 were screened through TREC-quantification in DBS with the Enlite Neonatal TREC-kit from PerkinElmer. A total of 222,857 newborns were screened, of which 48 tested positive. During the study period, three patients were diagnosed with SCID: an incidence of 1 in 74,187 newborns; 17 patients had clinically significant T-cell lymphopenia (non-SCID) with an incidence of 1 in 13,109 newborns who also benefited from the NBS program. The results obtained provide further evidence of the benefits of early diagnosis and curative treatment to justify the inclusion of this disease in NBS programs. A national NBS program is needed, also to define the exact SCID incidence in Spain

First universal newborn screening program for severe combined immunodeficiency in Europe: two-years' experience in Catalonia (Spain)

Early detection of this condition speeds up the establishment of appropriate treatment and increases the patient's life expectancy. Newborn screening for SCID started in January 2017 in Catalonia, the first Spanish and European region to universally include this testing. The results obtained in the first 2 years of experience are evaluated here. All babies born between January 2017 and December 2018 were screened. TREC quantification in DBS (1.5 mm diameter) was performed with the Enlite Neonatal TREC kit from PerkinElmer (Turku, Finland). In 2018, the retest cutoff in the detection algorithm was updated based on the experience gained in the first year, and changed from 34 to 24 copies/μL. This decreased the retest rate from 3.34 to 1.4% (global retest rate, 2.4%), with a requested second sample rate of 0.23% and a positive detection rate of 0.02%. Lymphocyte phenotype (T, B, NK populations), expression of CD45RA/RO isoforms, percentage and intensity of TCR αβ and TCR γδ, presence of HLA-DR+ T lymphocytes, and in vitro lymphocyte proliferation were studied in all patients by flow cytometry. Of 130,903 newborns screened, 30 tested positive, 15 of which were male. During the study period, one patient was diagnosed with SCID: incidence, 1 in 130,903 births in Catalonia. Thirteen patients had clinically significant T-cell lymphopenia (non-SCID) with an incidence of 1 in 10,069 newborns (43% of positive detections). Nine patients were considered false-positive cases because of an initially normal lymphocyte count with normalization of TRECs between 3 and 6 months of life, four infants had transient lymphopenia due to an initially low lymphocyte count with recovery in the following months, and three patients are still under study. The results obtained provide further evidence of the benefits of including this disease in newborn screening programs. Longer follow-up is needed to define the exact incidence of SCID in Catalonia

Early Diagnosis and Treatment of Purine Nucleoside Phosphorylase (PNP) Deficiency through TREC-Based Newborn Screening

Purine nucleoside phosphorylase (PNP) deficiency is a rare inherited disorder, resulting in severe combined immunodeficiency. To date, PNP deficiency has been detected in newborn screening only through the use of liquid chromatography tandem mass spectrometry. We report the first case in which PNP deficiency was detected by TREC analysis

Awake prone positioning for COVID-19 acute hypoxaemic respiratory failure: a randomised, controlled, multinational, open-label meta-trial

The risk of COVID-19 death is much greater and age dependent with type I IFN autoantibodies

International audienceSignificance There is growing evidence that preexisting autoantibodies neutralizing type I interferons (IFNs) are strong determinants of life-threatening COVID-19 pneumonia. It is important to estimate their quantitative impact on COVID-19 mortality upon SARS-CoV-2 infection, by age and sex, as both the prevalence of these autoantibodies and the risk of COVID-19 death increase with age and are higher in men. Using an unvaccinated sample of 1,261 deceased patients and 34,159 individuals from the general population, we found that autoantibodies against type I IFNs strongly increased the SARS-CoV-2 infection fatality rate at all ages, in both men and women. Autoantibodies against type I IFNs are strong and common predictors of life-threatening COVID-19. Testing for these autoantibodies should be considered in the general population
