Spectroscopic study of rock art paintings from the Cueva de Tito Bustillo (Ribadesella, Asturias)

Tres pictografías de la Cueva de Tito Bustillo se han estudiado por microespectroscopía Raman, espectroscopía infrarroja, difracción de rayos X, espectroscopía fotoelectrónica y microscopía electrónica y espectrometría de dispersión de energía de rayos X. Todas ellas se relacionan con las fases antiguas de la decoración de la cueva. Hematites de dos tamaños de grano (<1 y <10 µm) es el principal componente de las pictografías. Hidroxiapatito, anatasa y carbón amorfo aparecen como componentes adicionales en algunas de ellas. Calcita, cuarzo-α y minerales arcillosos se usan como materiales de relleno. No se han detectado aglutinantes orgánicos. Considerando los componentes principales, tamaño de grano y fases secundarias de los materiales pictóricos, se concluye que la veta de ocre de la cueva no se usó para hacer las pinturas de esta cronología. Dos de las pictografías analizadas parecen haber sido pintadas con un mismo tipo de pintura.Three pictographs from the Tito Bustillo cave have been studied by Raman microspectroscopy, infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy and scanning electronic microscopy combined with energy dispersive X-ray spectrometry. All the samples can be associated with the oldest cave decoration phases. Haematite of two granular sizes (<1 and <10 µm) is the main component of the pictographs. Hydroxyapatite, anatase and amorphous carbon appear as additional components in some of them. Calcite, α-quartz and clay minerals are used as filler materials. No organic binders have been detected. Considering the main components, granular size, and secondary phases of the pigments it is concluded that the ochre quarry of the cave was not used to make the paintings of this chronology. Two of the analysed figures of this cave seem to have been painted with the same type of paint

A Common Variant in the MC1R Gene (p.V92M) is associated with Alzheimer's Disease Risk.

Despite the recent identification of some novel risk genes for Alzheimer's disease (AD), the genetic etiology of late-onset Alzheimer's disease (LOAD) remains largely unknown. The inclusion of these novel risk genes to the risk attributable to the APOE gene accounts for roughly half of the total genetic variance in LOAD. The evidence indicates that undiscovered genetic factors may contribute to AD susceptibility. In the present study, we sequenced the MC1R gene in 525 Spanish LOAD patients and in 160 controls. We observed that a common MC1R variant p.V92M (rs2228479), not related to pigmentation traits, was present in 72 (14%) patients and 15 (9%) controls and confers increased risk of developing LOAD (OR: 1.99, 95% CI: 1.08-3.64, p = 0.026), especially in those patients whose genetic risk could not be explained by APOE genotype. This association remains and even increased in the subset of 69 patients with typical AD cerebrospinal fluid profile (OR: 3.40 95% CI: 1.40-8.27, p = 0.007). We did not find an association between p.V92M and age of onset of AD. Further studies are necessary to elucidate the role of MC1R in brain cells through the different MC1R pathways

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Impact of Pneumococcal Vaccination in the Nasopharyngeal Carriage of Streptococcus pneumoniae in Healthy Children of the Murcia Region in Spain.

An epidemiological study of Streptococcus pneumoniae nasopharyngeal carriage in healthy children was carried out five years after the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13). Study the impact of pediatric vaccination with PCV13, and other associated epidemiological factors on the status of nasopharyngeal carriage, the circulating pneumococcal serotypes, and the antibiotic susceptibility to more frequently used antibiotics. A multi-center study was carried out in Primary Health Care, which included 1821 healthy children aged 1 to 4 years old. All isolates were sent to the Spanish Pneumococcal Reference Laboratory for serotyping and antimicrobial susceptibility testing. At least one dose of PCV13 had been received by 71.9% of children and carriage pneumococcal prevalence was 19.7%. The proportion of PCV13 serotypes was low (14.4%), with an observed predominance of non-vaccine serotypes, 23B, 11A, 10A, 35B/F, and 23A were the five most frequent. A high rate of resistance to penicillin, erythromycin, and trimethoprim sulfamethoxazole was found. A low proportion of PCV13 serotypes were detected, confirming the impact of pediatric vaccination for reducing the serotypes vaccine carriage. High resistance rates to clinically important antibiotics were observed.This work was supported by Ministerio de Economía, Industria y Competitividad (MINECO)[grant SAF2017-83388].S

Resilience and psychological distress in pregnant women during quarantine due to the COVID-19 outbreak in Spain: a multicentre cross-sectional online survey

Purpose To examine the prevalence of depressive and anxiety symptoms and the corresponding risk factors among pregnant women during the confinement due to the COVID-19 outbreak in Spain. Materials and methods Between 15 April and 14 May 2020, a multicentre cross-sectional survey was performed to study depression, anxiety and resilience in a sample of Spanish pregnant women during the lockdown set up by the Government in response to COVID-19 pandemic outbreak. We designed an anonymous online self-administered questionnaire (https://bit.ly/34RRpq1) that included the Spanish validated versions of the Edinburgh Postpartum Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI) and the Connor-Davidson Resilience 10-items Scale (CD-RISC-10). Results A total of 514 pregnant women completed the survey. 72.8% had been confined < 40 days and 27.2% between 41 and 60 days. 182 (35.4%) participants scored over 10, with 21.3% scoring over 13 (75th Percentile) in depressive symptoms rates. We found high trait and anxiety scores, with 223 (43.4%) and 227 (44.2%) pregnant women scoring over the trait and state mean scores. Neither depression, anxiety or resilience levels showed any significant correlation with the length of confinement. We found low CD-RISC-10 scores. Conclusions We found a high prevalence of depression and anxiety symptoms during the quarantine, although we did not find an increased prevalence of psychological distress according to length of home confinement. Resilience correlated negatively with depression and anxiety
