Approach to illness and death of Vadinienses in roman Hispania (I-IV centuries)

Los vadinienses fueron un pueblo cántabro que habitó entre los siglos I y IV en el norte de la península ibérica -noreste de la actual provincia de León y la parte correspondiente de la actual Asturias-. En este trabajo se estudian las posibles causas de enfermedad y muerte de la población vadiniense representada en sus lápidas funerarias. Dos terceras partes de los vadinienses, según los datos de sus epitafios, murieron entre los 20-30 años, hallazgo que no se interpreta como representativo de la edad de muerte habitual en la época. Se consideran como las causas de muerte más probables las infecciones y las muertes violentas en competiciones deportivas o en accidentes laborales. Cuando se analiza de modo independiente al sexo femenino, casi la mitad de las fallecidas lo hicieron antes de los 20 años de edad, valorando como principales posibilidades las muertes relacionadas con embarazos y partos en edades muy precoces.The Vadinienses were a Cantabrian people who lived between the first and fourth centuries in the north of the Iberian Peninsula, northeast of the present province of León and the corresponding part of the current territory of Asturias. In this paper we study the possible causes of illness and death of the Vadinienses represented in their gravestones. The analysis of Vadinienses epitaphs shows that two-thirds of the deaths occurred in people between the ages of 20-30, a finding that is not interpreted as representative of the usual age of death at that time. The most likely causes of death are infections and violent deaths in sports competitions or work accidents. Analyzing females independently, almost half of the deceased were under the age of 20, being the main possibilities the deaths related to pregnancy and childbirth at very early ages

Endocarditis protésica precoz por un germen atípico, absceso perivalvular mitral: rocking motion

80 year-old patient with an incidental finding of thrombotic mitral valve disease. Prosthetic mitral endocarditis probably as a complication of the previous finding (B. hanselae). This cause is unique due to the unusual clinical presentation and the cause of the infection. The new multimodality imaging techniques were a key factor to establish a correct diagnosis.Paciente de 80 años de edad con afectación trombótica sobre válvula mitral prótesica diagnósticada de forma incidental, que posteriormente desarrolló una endocarditis precoz (B. Hanselae) sobre la misma zona. El germen causante de la infección es atípico y cursó como una endocarditis con cultivo negativo. Las técnicas de imagen fueron clave para poder establecer un diagnóstica y tratamiento adecuados

Proyectiles en ventrículo derecho. ¿Sin puerta de entrada?

The presence of intracardiac foreign bodies and their treatment are still a controversial issue given the variety of locations, the different clinical manifestations and the prognostic implications. The number of published cases in which there is no direct entrance site of the foreign body to the cardiac cavities, diagnosing or assuming theirembolization, is much more limited. We present the case of an adult male with cervical firearm wound, and two foreign bodies in the right ventricle without a direct entry door.La presencia de cuerpos extraños intracardiacos y su tratamiento suponen todavía un tema controvertido dada la variedad de localizaciones en las que se puede presentar y las diferentes manifestaciones clínicas e implicaciones pronósticas de cada una de ellas. El número de casos publicados en los que no existe puerta de entrada directa del cuerpo a las cavidades cardiacas, diagnosticando o asumiendo su embolización a distancia, es mucho más reducido. Presentamos el caso de un varón adulto con herida cervical por arma de fuego y dos cuerpos extraños alojados en ventrículo derecho sin puerta de entrada directa

Micellar Promoted Multi-Component Synthesis of 1,2,3-Triazoles in Water at Room Temperature

Micellar media in water provide a simple and efficient environment to favor the multi-component synthesis of 1,2,3-triazoles from organic bromides, sodium azide and terminal alkynes in the presence of [Cu(IMes)Cl] 1 catalyst at room temperature within few hours. The micellar medium favors both the in situ formation of the organic azide and its metal promoted cycloaddition with the alkyneMicellar media in water provide a simple and efficient environment favoring the multi-component synthesis of 1,2,3-triazoles from organic bromides, sodium azide and terminal alkynes in the presence of [Cu(IMes)Cl] 1 catalyst at room temperature within a few hours.

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Occurrence of SARS-CoV-2 viremia is associated with genetic variants of genes related to COVID-19 pathogenesis

IntroductionSARS-CoV-2 viral load has been related to COVID-19 severity. The main aim of this study was to evaluate the relationship between SARS-CoV-2 viremia and SNPs in genes previously studied by our group as predictors of COVID-19 severity.Materials and methodsRetrospective observational study including 340 patients hospitalized for COVID-19 in the University Hospital La Princesa between March 2020 and December 2021, with at least one viremia determination. Positive viremia was considered when viral load was above the quantifiable threshold (20 copies/ml). A total of 38 SNPs were genotyped. To study their association with viremia a multivariate logistic regression was performed.ResultsThe mean age of the studied population was 64.5 years (SD 16.6), 60.9% patients were male and 79.4% white non-Hispanic. Only 126 patients (37.1%) had at least one positive viremia. After adjustment by confounders, the presence of the minor alleles of rs2071746 (HMOX1; T/T genotype OR 9.9 p &lt; 0.0001), rs78958998 (probably associated with SERPING1 expression; A/T genotype OR 2.3, p = 0.04 and T/T genotype OR 12.9, p &lt; 0.0001), and rs713400 (eQTL for TMPRSS2; C/T + T/T genotype OR 1.86, p = 0.10) were associated with higher risk of viremia, whereas the minor alleles of rs11052877 (CD69; A/G genotype OR 0.5, p = 0.04 and G/G genotype OR 0.3, p = 0.01), rs2660 (OAS1; A/G genotype OR 0.6, p = 0.08), rs896 (VIPR1; T/T genotype OR 0.4, p = 0.02) and rs33980500 (TRAF3IP2; C/T + T/T genotype OR 0.3, p = 0.01) were associated with lower risk of viremia.ConclusionGenetic variants in HMOX1 (rs2071746), SERPING1 (rs78958998), TMPRSS2 (rs713400), CD69 (rs11052877), TRAF3IP2 (rs33980500), OAS1 (rs2660) and VIPR1 (rs896) could explain heterogeneity in SARS-CoV-2 viremia in our population

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe
