La fauna del pleistoceno inferior de la sierra de Quibas (Abanilla, Murcia)

El yacimiento kárstico cuaternario de la Sierra de Quibas (Abanilla, Murcia) ha proporcionado una amplia lista faunística constituida por 53 especies repartidas entre gasterópodos, miriápodos, anfibios, reptiles, aves y mamíferos. En el conjunto de los gasterópodos destaca Palaeoglandina, un género que se extingue en el resto de Europa durante el Plioceno y que se mantiene como relicto en el Pleistoceno de la Península Ibérica. Dos de las especies de aves determinadas, Gypaetus barbatus y Gerontieus eremita, y una de las serpientes, Elaphe cf. E. sealaris, apenas se hallan representadas en el registro fósil. Hay además varias especies de aves cuya aparición en Quibas supone la primera cita en el Pleistoceno inferior de la Península Ibérica. Entre los mamíferos posee una especial relevancia la presencia del cercopitécido Macaca sylvanus. La asociación de los taxones Arvieola deuealíon, Castillomys rivas rivas, Elíomys intermedius, Equus altidens y Capra sp. aff. C. alba permite la correlación con Plines 1, Orce 3 y Venta Micena, entre otros. El yacimiento de Quibas puede situarse, por tanto, antes del final del Pleistoceno inferior, con una antigüedad entre 1.3 y 1 Ma. Por lo que se refiere a las condiciones paleoclimáticas, podemos inferir a partir de la asociación faunística un régimen xerófilo, muy semejante al actual en el área geográfica, aunque quizás con valores de humedad y temperatura algo superiores. El entorno de la cavidad kárstica estaba formado por roquedo calcáreo con áreas abiertas de matorral, pero en las proximidades se desarrollaron humedales y zonas arboladas, como así lo atestigua la presencia de aves y micromamíferos típicos de estos hábitats.The Quaternary karstic site of Sierra de Quibas (Abanilla, Murcia, Spain) has provided a wide faunallist with 53 species distributed among gastropods, myriapods, amphibians, reptiles, birds and mammals. Especially interesting among the gastropods is Palaeoglandina that became extinct in Europe during the Pliocene. It remains as a relict genus in the Pleistocene of the Iberian Peninsula. Two of the birds, Gypaetus barbatus and Geronticus eremita, and a snake, Elaphe cf. E. sealaris, are scarcely represented in the fossil record. For several birds, it is the first record in the Lower Pleistocene of the Iberian Peninsula. Among the mammals, the presence of the Cercopithecine Macaca sylvanus is especially relevant. The assemblage of the taxa Arvicola deucalion, Castillomys rivas rivas, Eliomys intermedius, Equus altidens and Capra sp. aff. C. alba allows the correlation with Plines 1, Orce 3 and Venta Micena, among other sites. Therefore Quibas can be clated before the end of Lower Pleistocene, between 1.3 and 1 Ma. A dry paleoclimatic regime, very similar to the current climate in the geographical area, though perhaps slightly wetter and warmer, can be inferred from the faunal assemblage. The environment of the karstic cavity was a rocky place with open brushwood areas, but in the proximities there were wetlands and woodlands, as can be inferred from the presence of birds and micromammals characteristic of these [email protected] [email protected]

Effects of a Mediterranean Diet Intervention on Maternal Stress, Well-Being, and Sleep Quality throughout Gestation-The IMPACT-BCN Trial

Stress and anxiety are frequent occurrences among pregnant women. We aimed to evaluate the effects of a Mediterranean diet intervention during pregnancy on maternal stress, well-being, and sleep quality throughout gestation. In a randomized clinical trial, 1221 high-risk pregnant women were randomly allocated into three groups at 19-23 weeks' gestation: a Mediterranean diet intervention, a Mindfulness-Based Stress Reduction program, or usual care. All women who provided self-reported life-style questionnaires to measure their anxiety (State Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS)), well-being (WHO Five Well Being Index (WHO-5)), and sleep quality (Pittsburgh sleep quality index (PSQI)) at enrollment and at the end of the intervention (34-36 weeks) were included. In a random subgroup of 106 women, the levels of cortisol and related metabolites were also measured. At the end of the intervention (34-36 weeks), participants in the Mediterranean diet group had significantly lower perceived stress and anxiety scores (PSS mean (SE) 15.9 (0.4) vs. 17.0 (0.4), p = 0.035; STAI-anxiety mean (SE) 13.6 (0.4) vs. 15.8 (0.5), p = 0.004) and better sleep quality (PSQI mean 7.0 ± 0.2 SE vs. 7.9 ± 0.2 SE, p = 0.001) compared to usual care. As compared to usual care, women in the Mediterranean diet group also had a more significant increase in their 24 h urinary cortisone/cortisol ratio during gestation (mean 1.7 ± SE 0.1 vs. 1.3 ± SE 0.1, p < 0.001). A Mediterranean diet intervention during pregnancy is associated with a significant reduction in maternal anxiety and stress, and improvements in sleep quality throughout gestation.

Fungal microbiota dynamics and its geographic, age and gender variability in patients with cystic fibrosis

[Objectives] In cystic fibrosis (CF), there is a predisposition to bronchial colonization by potentially pathogenic microorganisms, such as fungi. Our aims were to describe the dynamics of respiratory mycobiota in patients with CF and to evaluate the geographic, age and gender variability in its distribution.[Methods] Cohort study in which 45 patients with CF from four hospitals in three Spanish cities were followed up during a 1-year period, obtaining spontaneous sputum samples every 3 to 6 months. Fungal microbiota were characterized by Internal Transcribed Spacer sequencing and Pneumocystis jirovecii was identified by nested PCR in a total of 180 samples.[Results] The presence of fungi were detected in 119 (66.11%) of the 180 samples and in 44 (97.8%) of the 45 patients: 19 were positive and 1 negative throughout all follow-ups and the remaining 25 presented alternation between positive and negative results. A total of 16 different genera were identified, with Candida spp. (50/180, 27.78%) and Pneumocystis spp. (44/180, 24.44%) being the most prevalent ones. The distribution of fungal genera was different among the evaluated centres (p < 0.05), by age (non-adults aged 6–17 years vs. adults aged ≥18 years) (p < 0.05) and by gender (p < 0.05).[Discussion] A high prevalence of fungal respiratory microbiota in patients with CF was observed, whose dynamics are characterized by the existence of multiple cycles of clearance and colonization, reporting the existence of geographic, age and gender variability in the distribution of fungal genera in this disease.The study was supported by the Spanish Ministry of Science and Innovation (grant number FIS-PS09/00957), by Plan Andaluz de Investigación, Desarrollo e Innovación, Consejería de Economía Conocimiento, Empresas y Universidad de la Junta de Andalucía (grant number PS20_00894), and by Consejería de Salud y Familia, Junta de Andalucía (grant number CSyF Exp.

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

Detailed stratified GWAS analysis for severe COVID-19 in four European populations

Given the highly variable clinical phenotype of Coronavirus disease 2019 (COVID-19), a deeper analysis of the host genetic contribution to severe COVID-19 is important to improve our understanding of underlying disease mechanisms. Here, we describe an extended genome-wide association meta-analysis of a well-characterized cohort of 3255 COVID-19 patients with respiratory failure and 12 488 population controls from Italy, Spain, Norway and Germany/Austria, including stratified analyses based on age, sex and disease severity, as well as targeted analyses of chromosome Y haplotypes, the human leukocyte antigen region and the SARS-CoV-2 peptidome. By inversion imputation, we traced a reported association at 17q21.31 to a ~0.9-Mb inversion polymorphism that creates two highly differentiated haplotypes and characterized the potential effects of the inversion in detail. Our data, together with the 5th release of summary statistics from the COVID-19 Host Genetics Initiative including non-Caucasian individuals, also identified a new locus at 19q13.33, including NAPSA, a gene which is expressed primarily in alveolar cells responsible for gas exchange in the lung.S.E.H. and C.A.S. partially supported genotyping through a philanthropic donation.

In vitro activity of Etanidazole against the protozoan parasite Trypanosoma cruzi

We investigated the in vitro action of an hydrosoluble 2-nitroimidazole, Etanidazole (EZL), against Trypanosoma cruzi, the etiologic agent of Chagas disease. EZL displayed lethal activity against isolated trypomastigotes as well as amastigotes of T. cruzi (RA strain) growing in Vero cells or J774 macrophages, without affecting host cell viability. Although not completely equivalent to Benznidazole (BZL), the reference drug for Chagas chemotherapy, EZL takes advantage in exertingits anti-T. cruzi activity for longer periods without serious toxic side effects, as those recorded in BZL-treated patients. Our present results encourage further experiments to study in depth the trypanocidal properties of this drug already licensed for use in human cancers

Cross-sectional study of the healthcare provided by a medicalized helicopter from Extremadura (Spain)

[Objective]: To analyze geographic dispersion, demographic factors, clinical features of patients attended and response times of a helicopter emergency medical service in a region of Spain. [Methods]: According to the principles of the Declaration of Helsinki and to the standards of Good Clinical Practice, a cross-sectional observational study from January 2014 to December 2016 was carried out. Socio-demographic, clinical and transfer related variables were analyzed from an anonymized database loaned by the service.[Results]: 642 missions were flown (on average 0.59 flights per day). The patients were 65.6% males (they were significantly younger than women were) and 79% older than 45. Primary transfers composed 68.8% of cases. Medical pathologies were the most prevalent (74.9%), followed by traumatic pathologies (19.8%). Cardiovascular pathologies took up 68.8% of attended medical pathologies and 51.56% of the total of recorded cases. The accident rate was 20.25% and the response time in 75% of cases was under 32 min. Twenty deceased patients were registered (70% males).[Conclusions]: This study reports for the international community the features of several Spanish HEMS and profile of patients attended. Adult men are a common profile and cardiovascular issues have replaced traumatic issues as main healthcare demand. However, it should be confirmed because it could be due to differences in local profile of patients. Men had higher risk of road traffic and occupational accidents as well as a higher mortality than women did. Socio-demographical and organizational aspects have been provided that could be taken into consideration to implement new air emergency services

Pneumocystis jirovecii en recién nacidos pretérmino: prevalencia y posibles implicaciones clínicas

1 página. IX Jornadas de Salud Investiga. Cádiz 20-22 octubre, 2010.Pneumocystis jirovecii, conocido previa-mente como Pneumocystis carinii sp. f. hominis, es un hongo oportunista atípico, no cultivable, que infecta exclusivamente al ser humano y del que se desconocen aún muchos aspectos de su epidemiología y fisiopatología. La vía aérea se supone la forma de transmisión más importante en la especie humana, pero recientemente se ha podido comprobar su capacidad de transmisión transplacentaria. En modelos animales la infección por Pneumocystis produce disminución de las proteínas B y C del surfactante pulmonar, sustancia tensoactiva cuyo déficit constituye la base del síndrome de distrés respiratorio neonatal (SDRN). El objetivo de nuestro trabajo fue conocer la prevalencia de infección por P. jirovecii en neonatos prematuros y su posible relación con el SDRN.Peer reviewe
